The Long Life of the ‘Perfect’ Woman

What did happen to Elsie Scheel, the “perfect” woman mentioned in an article in Wednesday’s New York Times that described how people considered overweight had a slightly lower risk of dying than those of normal weight?

A century ago, at age 24, Miss Scheel was the subject of a spate of news media coverage after the “medical examiner of the 400 ‘co-eds’ ” at her college, Cornell University, described her as the epitome of “perfect health,” according to a 1912 New York Times article. That article and others also gave her dimensions: 5-foot-7 and 171 pounds, which would have corresponded to a body mass index of 27, putting Miss Scheel in the overweight category. Miss Scheel, it turns out, lived a long life, dying in 1979 in St. Cloud, Fla., three days shy of her 91st birthday.

But though it may be tempting to conclude that Miss Scheel’s longevity exemplifies the benefits of a not-too-low B.M.I, her case is only one anecdote, of course. And, according to family members and to hints provided in early articles, she was a person who valued being active and athletic, had a strong and confident attitude, and, as a daughter of a doctor and a mother of a doctor, may have been steeped in healthy habits that were much more relevant to her survival than her weight.

“She never took an aspirin or a Tylenol,” a granddaughter, Karen Hirsh Meredith, of Broken Arrow, Okla., said in an interview Wednesday. She kept up hobbies like stamp collecting and wrote pieces for the St. Cloud newspaper. And, Ms. Meredith said, “she was still driving late in life.”

Ms. Meredith said she did not recall her grandmother having any illnesses or being hospitalized except for shortly before she died, when she went into the hospital with stomach pain. She ended up having surgery for a perforated bowel and died the next day, Ms. Meredith said.

A death notice said Miss Scheel, who was Mrs. Hirsh when she died, had been a “practical nurse,” although Ms. Meredith said the family believed she did not work after she had children. In 1918 she married Frederick Rudolph Hirsh, an architect who supervised the building of the New York Public Library and who was a widower with two children, Frederick Jr. and Mary. He died in 1933 at 68, leaving his wife to raise a son, John, and a daughter, Elise. She moved to Florida from Mount Vernon, N.Y., in the 1940s and never remarried.

Miss Scheel’s mother, Sophie Bade Scheel, a physician educated at New York Medical College, maintained an active medical practice at a time when relatively few women did. And Miss Scheel may have benefited from good genes: her three siblings were 79, 88 and 93 when they died.

Published reports from 1912 and 1913 provide glimpses of the type of person Miss Scheel was and of her immediate-post-"perfect” experience.

She participated in many sports, playing basketball at Cornell. “I play a guard, where my weight helps,” she told a newspaper. She was a suffragette and, the Times article said, “doesn’t know what fear is.”

She ate only three meals every two days, loved beefsteak and shunned candy and caffeine. An article in The Oregonian asked her about her advice for healthy living, reporting that “Miss Scheel feels that the average girl does too much of the wrong sort of thing — too many dances and not enough good bracing tramps. I just got back from a 25-mile tramp to Enfield Falls.”

Some of the news media coverage was catty, even brutal. And it was extremely detailed. Her particulars — the size of her chest, waist and hips — were compared to the Venus de Milo.

A day after the Times article, The New York Herald ran a story about Miss Scheel above the fold on its front page: “Brooklyn Venus Much Too Large is Verdict of Physical Culturists.” These “physical culturists” claimed that Miss Scheel’s weight and height “cannot be reconciled with the accepted ideal of female beauty.”

Car Sales End Strong Year on Modest Note

DETROIT – Automakers ended 2012 with modest sales results in the United States, capping a strong year and promising more growth in 2013.

Based on early reports Thursday, analysts predicted a 10 percent increase overall for the industry for December, a gain that would put the year’s sales at about 14.5 million – the best performance since 2007.

The three Detroit car companies all posted sales gains in December, solidifying improvements made throughout year because of consumers replacing their aging cars and trucks.

General Motors, the largest American automaker, said its December sales increased 4.9 percent, primarily because of new products such as the Cadillac ATS sedan and higher incentives on its Chevrolet Silverado and GMC Sierra pickups.

The company had been losing ground in the high-profit pickup truck segment until it added discounts to the Silverado, which posted a 6.1 percent sales increase in December, and the Sierra, which was up 13.4 percent.

For the year, G.M. sold 2.59 million vehicles, an increase of 3.7 percent from 2011. That lagged the overall gains in the market, which were about 14 percent industrywide for the year.

G.M.'s head of United States sales, Kurt McNeil, said the company expects significant growth in 2013, with industry sales as high as 15.5 million. He noted that the resolution of fiscal negotiations in Washington removed some potential concerns for consumers shopping for new vehicles.

“We are especially pleased that the politicians on both sides of the aisle in Washington were able to compromise,” Mr. McNeil said in a conference call with analysts and media Thursday. “The short-term crisis has passed.”

Ford Motor Company reported a slight sales increase of 1.9 percent in December as safety recalls for its new Escape SUV and Fusion sedan depressed results.

Ford said that sales of the Fusion dropped 10.8 percent during the month and Escape sales slid 21.3 percent. The company has been plagued with multiple recalls on engines and other parts on the vehicles, which are usually among its strongest sellers.

The drop was mitigated by strong results for Ford’s two smallest cars, the Focus, which increased in sales by 58.3 percent, and the Fiesta, which was up by 52.8 percent.

For all of 2012, Ford’s United States sales increased 4.7 percent to 2.25 million vehicles. Ken Czubay, head of Ford’s domestic sales and marketing, said the company’s small-car sales were its best in more than a decade.

Ford predicted that industry sales in 2013 could reach 16 million vehicles, as more Americans replace older models with new, more fuel-efficient ones.

Chrysler, the smallest of the Detroit companies, was again the star performer in December, with a 10 percent increase.

The company’s new compact car, the Dodge Dart, showed improvement with a 36 percent gain from the prior month. In fact, much of Chrysler’s lineup – ranging from Jeep SUVs to the tiny Fiat 500 micro-car – posted sales records for the month of December.

For the year, Chrysler sold 1.65 million vehicles, a 21 percent increase from 2011.

The major foreign automakers were expected to report results later in day. In a partial report, Toyota, the biggest of the Japanese manufacturers, said that it sold 2 million vehicles in the United States during 2012, a 26.6 percent increase from the year before.

Kim Jong-un, North Korean Leader, Makes Overture to South

SEOUL, South Korea — The North Korean leader, Kim Jong-un, called for an end to the “confrontation” with rival South Korea on Tuesday in what appeared to be an overture to the incoming South Korean president as she was cobbling together South Korea’s new policy on the North.

North Korea issued a major policy statement on New Year’s Day, following a tradition set by Mr. Kim’s grandfather, the North Korean founder Kim Il-sung, and continued by his father, Kim Jong-il, who died in December 2011, bequeathing the dynastic rule to Mr. Kim.

Although Mr. Kim inherited the central policies of his father, outside analysts see him as trying to distance himself in a variety of ways from his father’s ruling style. Kim Jong-il was more feared than respected among his people, and his rule was marked by a major famine.

The most significant feature of Kim Jong-un’s speech was its marked departure of tone regarding South Korea.

“A key to ending the divide of the nation and achieving reunification is to end the situation of confrontation between the North and the South,” Mr. Kim said. “A basic precondition to improving North-South relations and advancing national reunification is to honor and implement North-South joint declarations.”

He was referring to two inter-Korean agreements, signed in 2000 and 2007, when two South Korean presidents, Kim Dae-jung and Roh Moo-hyun, were pursuing a “Sunshine Policy” of reconciliation and economic cooperation with North Korea and met Mr. Kim’s father in the North Korean capital, Pyongyang.

As a result of those agreements, billions of dollars of South Korean investment, aid and trade flowed into the North. Billions more were promised in investments in shipyards and factory parks, as the South Korean leaders believed that economic good will was the best way of encouraging North Korea to shed its isolation and hostility while reducing the economic gap between the Koreas and the cost of reunification in the future.

But that warming of ties ended when conservatives came to power in South Korea with the inauguration of President Lee Myung-bak in 2008. Mr. Lee suspended any large aid or investment because of the lack of progress toward dismantling the North’s nuclear weapons programs, and inter-Korean relations spiraled down, further aggravated by the North’s shelling of a South Korean island in 2010.Mr. Kim’s speech on Tuesday, which was broadcast through the North’s state-run television and radio stations, was another sign that the young leader was trying to emulate his grandfather, who was considered a more people-friendly leader and is still widely revered among North Koreans.

Mr. Kim returned to the tradition of Kim Il-sung, issuing the statement in a personal speech. During the rule of Kim Jong-il, the statement — which laid out policy guidelines for the new year and was studied by all branches of the party, state and military — was issued as a joint editorial of the country’s main official media.

In his speech, Kim Jong-un, echoed themes of previous New Year’s messages, emphasizing that improving the living standards of North Koreans and rejuvenating the agricultural and light industries were among the country’s main priorities.

But he revealed no details of any planned economic policy changes. He mentioned only a need to “improve economic leadership and management” and “spread useful experiences created in various work units.”

Since July, reports from various media suggest that Mr. Kim’s government has begun carrying out cautious economic incentives aimed at bolstering productivity at farms and factories. Some reports said the state was considering letting farmers keep at least 30 percent of their yield; currently, it is believed, they are allowed to sell only a surplus beyond a government-set quota that is rarely met.

Mr. Kim also vowed to strengthen his country’s military, calling for the development of more advanced weapons. But he made no mention of relations with the United States or the international efforts to halt North Korea’s nuclear weapons program. He simply reiterated that his government was willing to “expand and improve upon friendly and cooperative relationships with all countries friendly to us.”

Mr. Kim’s speech followed the successful launching of a satellite aboard a long-range rocket in December. North Korea’s propagandists have since been busy billing the launch as a symbol of what they called the North’s soaring technological might and Mr. Kim’s peerless leadership. Washington considered it a test of long-range ballistic-missile technology and a violation of United Nations Security Council resolutions banning such tests, and is seeking more sanctions to impose on the isolated country.

The incoming leader of South Korea, Park Geun-hye, who was the presidential candidate of Mr. Lee’s conservative governing party, did not immediate respond to the speech. Ms. Park is the daughter of Park Chung-hee, the former military strongman under whose rule from 1961 until 1979 a staunchly anti-Communist, pro-American political establishment took root in South Korea.

North Korea had engineered a couple of assassination attempts on Ms. Park’s father, one of which resulted in her mother’s death in 1974. But Ms. Park also traveled to Pyongyang in 2002 and discussed inter-Korean reconciliation with Kim Jong-il.

During her campaign for president, she said that if elected, she would decouple humanitarian aid from politics and try to hold a summit meeting with Kim Jong-un. She was in part reacting to widespread criticism in South Korea that Mr. Lee’s hard-line policy did little to change the North’s behavior.

During the campaign, however, Ms. Park stuck to Mr. Lee’s stance on the most contentious issue of large-scale investment, which the North considers crucial. Ms. Park, like the current president, insisted that any large-scale economic investments be preceded by the “building of trust” through progress in curbing North Korea’s nuclear weapons program.

Peace bought with “shoveling” of unrestrained aid under the Sunshine Policy was “a fake,” she said, citing the North’s long history of using military threats to win economic concessions.

Earlier, North Korea called her a “confrontational maniac” and “fascist.” But since her election, it has refrained from attacking her.

Some Companies Seek to Wean Employees From Their Smartphones

Resolutions to change behavior are common at this time of year, but they usually involve exercising more or smoking less. Now, some companies are adopting policies aimed at weaning employees from their electronic devices.

Matthew Ryan Williams for The New York Times

Michelle Barry and Mark Jacobsen of Centric Brand Anthropology strive for the elusive work-life balance.

Atos, an international information technology company, plans to phase out all e-mails among employees by the end of 2013 and rely instead on other forms of communication. And starting in the new year, employees at Daimler, the German automaker, can have incoming e-mail automatically deleted during vacations so they do not return to a flooded in-box. An automatic message tells the sender which person is temporarily dealing with the employee’s e-mail.

No one is expected to be on call at all hours of the day and night, and “switching off” after work is important, “even if you are on a business trip,” said Sabrina Schrimpf, a Daimler spokeswoman, referring to the company’s recently released report, “Balanced! — Reconciling Employees’ Work and Private Lives.”

Disconnecting can be more challenging for business travelers who frequently work across time zones.

And there is a ripple effect, said Leslie A. Perlow, a professor of leadership at Harvard Business School and the author of “Sleeping With Your Smartphone.” “These guys fly in the middle of the night and send e-mails back to colleagues” who wait up, ready to respond.

A study conducted last spring by the Pew Research Center’s Internet and American Life Project found that while mobile phones were valued as a way to stay productive, there were downsides to being available at all times. The nationwide survey of 2,254 adults found that 44 percent of cellphone owners had slept with their phone next to their bed and that 67 percent had experienced “phantom rings,” checking their phone even when it was not ringing or vibrating. Still, the proportion of cellphone owners who said they “could live without it” has gone up, to 37 percent from 29 percent in 2006.

Sam Chapman, chief executive of Empower Public Relations in Chicago, said he used to feel phantom vibrations and frequently read and sent e-mail on his BlackBerry in the middle of the night. He slept poorly, did not feel refreshed in the morning and considered himself addicted. “I wanted to make sure that what happened to me didn’t happen to my employees,” he said.

So Mr. Chapman adopted what he called a BlackBerry blackout policy. He and his staff of about 20 turn off their BlackBerrys from 6 p.m. to 6 a.m. on weekdays and completely on weekends for all work-related use, with rare exceptions. “When I’m well rested, I show up to work ready to go,” he said.

He maintains that regimen while traveling, and said the policy had increased company productivity.

Professor Perlow agreed that companies could improve their bottom line by encouraging employees to disconnect at times. “Being constantly on actually undermines productivity,” she said.

But it is not always easy. In early 2012, when Michelle Barry, Mark Jacobsen and a third partner created Centric Brand Anthropology, a Seattle-based company that advises clients on brand strategy, design and culture management, they gave serious thought to the issue.

“A huge priority for us was to have a good balance between work-life,” said Mr. Jacobsen, Centric’s vice president and creative director. “Yet we have found that very difficult to do while working with large multinational clients,” which often require international travel and constant availability.

Being a start-up compounded those challenges. “Just because you can e-mail at 2 a.m., doesn’t mean it’s a good thing,” he said.

Centric encourages employees to prepare a week before a trip, designating a colleague as backup, informing clients about their travel plans, and trying to avoid deadlines immediately after they return. Employees are also encouraged to take spouses or partners on longer assignments and to build in downtime, said Ms. Barry, the company’s president and chief executive. When traveling, she said, “I make a commitment to myself not to stay up all night answering e-mails.”

Experts say there is no firm data for how many companies have policies restricting the use of electronic devices outside the office. “The companies I know actively encourage workers to stay connected after hours and on weekends,” said Dennis J. Garritan, a managing partner of the private equity firm Palmer Hill Capital and an adjunct professor at Harvard Business School.

Employers Must Offer Family Health Care, Affordable or Not, Administration Says

WASHINGTON — In a long-awaited interpretation of the new health care law, the Obama administration said Monday that employers must offer health insurance to employees and their children, but will not be subject to any penalties if family coverage is unaffordable to workers.

The requirement for employers to provide health benefits to employees is a cornerstone of the new law, but the new rules proposed by the Internal Revenue Service said that employers’ obligation was to provide affordable insurance to cover their full-time employees. The rules offer no guarantee of affordable insurance for a worker’s children or spouse. To avoid a possible tax penalty, the government said, employers with 50 or more full-time employees must offer affordable coverage to those employees. But, it said, the meaning of “affordable” depends entirely on the cost of individual coverage for the employee, what the worker would pay for “self-only coverage.”

The new rules, to be published in the Federal Register, create a strong incentive for employers to put money into insurance for their employees rather than dependents. It is unclear whether the spouse and children of an employee will be able to obtain federal subsidies to help them buy coverage — separate from the employee — through insurance exchanges being established in every state. The administration explicitly reserved judgment on that question, which could affect millions of people in families with low and moderate incomes.

Many employers provide family coverage to full-time employees, but many do not. Family coverage is much more expensive, and the employee’s share of the premium is typically much larger.

In 2012, according to an annual survey by the Kaiser Family Foundation, premiums for employer-sponsored health insurance averaged $5,615 a year for single coverage and $15,745 for family coverage. The employee’s share of the premium averaged $951 for individual coverage and more than four times as much, $4,316, for family coverage.

Starting in 2014, most Americans will be required to have health insurance. Low- and middle-income people can get tax credits to help pay their premiums, unless they have access to affordable coverage from an employer.

In its proposal, the Internal Revenue Service said, “Coverage for an employee under an employer-sponsored plan is affordable if the employee’s required contribution for self-only coverage does not exceed 9.5 percent of the employee’s household income.”

The rules, though labeled a proposal, are more significant than most proposed regulations. The Internal Revenue Service said employers could rely on them in making plans for 2014.

In writing the law, members of Congress often conjured up a picture of employees working year-round at full-time jobs. But in drafting the rules, the I.R.S. wrestled with the complex reality of part-time, seasonal and temporary workers.

In addition, the administration expressed concern that some employers might try to evade the new requirements by firing and rehiring employees, manipulating their work hours or using temporary staffing agencies. The rules include several provisions to prevent such abuse.

The law says an employer with 50 or more full-time employees may be subject to a tax penalty if it fails to offer coverage to “its full-time employees (and their dependents).”

Employers asked for guidance, and the Obama administration provided it, saying that a dependent is an employee’s child under the age of 26.

“Dependent does not include the spouse of an employee,” the proposed rules say.

Thus, employers must offer coverage to children of an employee, but do not have to make it affordable. And they do not have to offer coverage at all to the spouse of an employee.

The administration said that the rules — which apply to private businesses, nonprofit organizations and state and local government agencies — would require changes at many work sites.

“A number of employers currently offer coverage only to their employees, and not to dependents,” the I.R.S. said. “For these employers, expanding their health plans to add dependent coverage will require substantial revisions to their plans.”

In view of this challenge, the agency said it would grant a one-time reprieve to employers who fail to offer coverage to dependents of full-time employees, provided they take steps in 2014 to come into compliance. Under the rules, employers must offer coverage to employees in 2014 and must offer coverage to dependents as well, starting in 2015.

The new rules apply to employers that have at least 50 full-time employees or an equivalent combination of full-time and part-time employees. A full-time employee is a person employed on average at least 30 hours a week. And 100 half-time employees are considered equivalent to 50 full-time employees.

Thus, the government said, an employer will be subject to the new requirement if it has 40 full-time employees working 30 hours a week and 20 half-time employees working 15 hours a week.

Scant Proof Is Found to Back Up Claims by Energy Drinks

Energy drinks are the fastest-growing part of the beverage industry, with sales in the United States reaching more than $10 billion in 2012 — more than Americans spent on iced tea or sports beverages like Gatorade.

Their rising popularity represents a generational shift in what people drink, and reflects a successful campaign to convince consumers, particularly teenagers, that the drinks provide a mental and physical edge.

The drinks are now under scrutiny by the Food and Drug Administration after reports of deaths and serious injuries that may be linked to their high caffeine levels. But however that review ends, one thing is clear, interviews with researchers and a review of scientific studies show: the energy drink industry is based on a brew of ingredients that, apart from caffeine, have little, if any benefit for consumers.

“If you had a cup of coffee you are going to affect metabolism in the same way,” said Dr. Robert W. Pettitt, an associate professor at Minnesota State University in Mankato, who has studied the drinks.

Energy drink companies have promoted their products not as caffeine-fueled concoctions but as specially engineered blends that provide something more. For example, producers claim that “Red Bull gives you wings,” that Rockstar Energy is “scientifically formulated” and Monster Energy is a “killer energy brew.” Representative Edward J. Markey of Massachusetts, a Democrat, has asked the government to investigate the industry’s marketing claims.

Promoting a message beyond caffeine has enabled the beverage makers to charge premium prices. A 16-ounce energy drink that sells for $2.99 a can contains about the same amount of caffeine as a tablet of NoDoz that costs 30 cents. Even Starbucks coffee is cheap by comparison; a 12-ounce cup that costs $1.85 has even more caffeine.

As with earlier elixirs, a dearth of evidence underlies such claims. Only a few human studies of energy drinks or the ingredients in them have been performed and they point to a similar conclusion, researchers say — that the beverages are mainly about caffeine.

Caffeine is called the world’s most widely used drug. A stimulant, it increases alertness, awareness and, if taken at the right time, improves athletic performance, studies show. Energy drink users feel its kick faster because the beverages are typically swallowed quickly or are sold as concentrates.

“These are caffeine delivery systems,” said Dr. Roland Griffiths, a researcher at Johns Hopkins University who has studied energy drinks. “They don’t want to say this is equivalent to a NoDoz because that is not a very sexy sales message.”

A scientist at the University of Wisconsin became puzzled as he researched an ingredient used in energy drinks like Red Bull, 5-Hour Energy and Monster Energy. The researcher, Dr. Craig A. Goodman, could not find any trials in humans of the additive, a substance with the tongue-twisting name of glucuronolactone that is related to glucose, a sugar. But Dr. Goodman, who had studied other energy drink ingredients, eventually found two 40-year-old studies from Japan that had examined it.

In the experiments, scientists injected large doses of the substance into laboratory rats. Afterward, the rats swam better. “I have no idea what it does in energy drinks,” Dr. Goodman said.

Energy drink manufacturers say it is their proprietary formulas, rather than specific ingredients, that provide users with physical and mental benefits. But that has not prevented them from implying otherwise.

Consider the case of taurine, an additive used in most energy products.

On its Web site, the producer of Red Bull, for example, states that “more than 2,500 reports have been published about taurine and its physiological effects,” including acting as a “detoxifying agent.” In addition, that company, Red Bull of Austria, points to a 2009 safety study by a European regulatory group that gave it a clean bill of health.

But Red Bull’s Web site does not mention reports by that same group, the European Food Safety Authority, which concluded that claims about the benefits in energy drinks lacked scientific support. Based on those findings, the European Commission has refused to approve claims that taurine helps maintain mental function and heart health and reduces muscle fatigue.

Taurine, an amino acidlike substance that got its name because it was first found in the bile of bulls, does play a role in bodily functions, and recent research suggests it might help prevent heart attacks in women with high cholesterol. However, most people get more than adequate amounts from foods like meat, experts said. And researchers added that those with heart problems who may need supplements would find far better sources than energy drinks.

The North Korean Leader, Kim Jong-un, Makes Overture to South

SEOUL, South Korea — The North Korean leader, Kim Jong-un, called for an end to the “confrontation” with rival South Korea on Tuesday in what appeared to be an overture to the incoming South Korean president as she was cobbling together South Korea’s new policy on the North.

North Korea issued a major policy statement on Tuesday, New Year’s Day, following a tradition set by Mr. Kim’s late grandfather, the North Korean founder Kim Il-sung, and his late father, Kim Jong-il, who died in December last year, bequeathing the dynastic rule to Mr. Kim.

Mr. Kim was the first supreme North Korean leader to issue the statement as his personal speech since his grandfather last did so before his death in 1994. During the rule of his reclusive father, Kim Jong-il, the statement — which laid out policy guidelines for the new year and was studied by all branches of the party, state and military — was issued as a joint editorial of the country’s main official media.

Mr. Kim’s speech on Tuesday, which was broadcast through the North’s state-run television and radio stations, was another sign that the young leader was trying to imitate his grandfather Kim Il-sung, who in life was considered a more people-friendly leader and is still widely revered among North Koreans.

Although Mr. Kim inherited the key policies of his father, outside analysts see him as trying to distance himself from the ruling style of his father, Kim Jong-il, who was more feared than respected among his people and whose rule was marked by a famine.

In his speech, Mr. Kim, echoed themes of previous New Year’s messages, emphasizing that improving the living standards of North Koreans and rejuvenating the agricultural and light industries were among the improvised country’s main priorities.

But he revealed no details of any planned economic policy changes. He only mentioned a need to “improve economic leadership and management” and “spread useful experiences created in various work units.”

Since July, various news outlets in South Korea have reported that Mr. Kim’s regime has begun carrying out cautious economic incentives aimed at bolstering productivity at farms and factories. Some reports said the state was considering letting farmers keep at least 30 percent of their yield; currently, it is believed, they are allowed to sell only a surplus beyond a government-set quota that is rarely met.

Mr. Kim also vowed to strengthen his country’s military, calling for the development of more advanced weapons. But he made no mention of relations with the United States or the international efforts to halt North Korea’s nuclear weapons program. He simply reiterated that his government was willing to “expand and improve upon friendly and cooperative relationships with all countries friendly to us.”

Mr. Kim’s speech followed the successful launching of a satellite aboard a long-range rocket in December. North Korea’s propagandists have since been busy billing the launch as a symbol of what they called the North’s soaring technological might and Mr. Kim’s peerless leadership. Washington considered it a test of long-range ballistic missile technology and a violation of United Nations Security Council resolutions banning such tests, and is seeking more sanctions to impose on the isolated country.

But it was his allusion to relations with South Korea that signified a departure in tone.

“A key to ending the divide of the nation and achieving reunification is to end the situation of confrontation between the North and the South,” Mr. Kim said. “A basic precondition to improving North-South relations and advancing national reunification is to honor and implement North-South joint declarations.”

He was referring to two inter-Korean summit agreements, signed in 2000 and 2007, when two South Korean presidents, Kim Dae-jung and Roh Moo-hyun, were pursuing a “Sunshine Policy” of reconciliation and economic cooperation with North Korea and met Mr. Kim’s father in the North Korean capital, Pyongyang.

As a result of those agreements, billions of dollars of South Korean investment, aid and trade flowed into the North. Billions more were promised in investments in shipyards and factory parks, as the South Korean leaders believed that economic good will was the best way of encouraging North Korea to shed its isolation and hostility while reducing the economic gap between the two Koreas and the cost of reunification in the future.

But that warming of ties ended when conservatives came to power in South Korea with the inauguration of President Lee Myung-bak in 2008. When Mr. Lee was president-elect, North Korea offered a similar overture as Tuesday’s. But Mr. Lee suspended any large aid or investment barring a significant progress toward dismantling the North’s nuclear weapons programs, and inter-Korean relations spiraled down, further aggravated by the North’s shelling of a South Korean island in 2010.

The incoming leader of South Korea, Park Geun-hye, who is the presidential candidate of Mr. Lee’s governing party, kept the conservatives in power by winning the Dec. 19 election. She is the daughter of Park Chung-hee, the former military strongman under whose rule from 1961 till 1979 a staunchly anti-Communist, pro-American political establishment took root in South Korea.

North Korea had engineered a couple of assassination attempts on Ms. Park’s father, one of which resulted in her mother’s death in 1974. But Ms. Park also traveled to Pyongyang in 2002 and discussed inter-Korean reconciliation with Kim Jong-il.

During her campaign for president, she said that if elected, she would decouple humanitarian aid from politics and try to hold a summit meeting with Kim Jong-un. She was in part reacting to widespread criticism in South Korea that Mr. Lee’s hard-line policy did little to change the North’s behavior.

During the campaign, however, Ms. Park stuck to Mr. Lee’s stance on the most contentious issue of large-scale investment, which the North considers crucial.

Ms. Park, like the current president, insisted that any large-scale economic investments be preceded by the “building of trust” through progress in denuclearizing North Korea.

Peace bought with “shoveling” of unrestrained aid under the Sunshine Policy was “a fake,” she said, citing the North’s long history of using military threats to win economic concessions.

North Korea called her a “confrontational maniac” and “fascist.” But since her election, it has refrained from attacking her.
