본 연구의 목적은 경중도 비만여성의 대상으로 유산소 운동의 강도 차이가 렙틴과내장지방량 변화에 차이가 있는가를 알아보는 것이다. 본 연구 피험자는 D광역시에 있는 헬스클럽에 처음으로 등록한 여성으로 BMI수준이 25∼30사이의 경중도 비만 여성을 대상으로 목표심박수를 50%, 60%, 70%로 각 집단의 운동 강도에 차이를 두어 12주간 실시한 결과 다음과 같다. 첫째 저강도(60-70%) 운동이 렙틴 감소 농도 감소에 효과가 있는 것으로 나타났으나, 운동강도에서는 차이가 없는 것으로 나타났다. 둘째 저강도 운동이 내장지방량에 효과가 있는 것으로 나타났으나 운동강도별 차이가 없는 것으로 나타났다. 이 연구 결과로서 유산소 운동은 렙틴과 내장지방량을 줄이는데 효과가 있는 것으로 나타났으나 운동강도에 따른 변화는 없는 것으로 나타났다. 선행연구와 마찬가지로 유산소 운동이 지방조직으로부터 분비되고 시상하부의 전달 물질인 렙틴이 활동함으로서 내장지방량에 영향을 미친 것으로 사료된다. 동일 칼로리 소비시 저강도 운동이 지방분해에 더 효과가 있는 것으로 판단되며, 비만해소에 효과적인 운동강도를 제시하고자 했으나 여러가지 호르몬의 변인, 영양섭취, 각 집단별 칼로리 소비 차이 등으로 인해 명확한 운동강도를 제시하지 못했다. This study aims to find out the difference of the leptin and visceral fat amount for the severity obesity women from the aerobic exercise intensity difference. The subjects of this experiment are the severity obesity women who registered in the health club for the first time in D metropolitan city, with BMI level from 25 to 30 dividing targeting heart rate 50%, 60%, and 70% of the exercise intensity difference for 12 weeks. The results are as below. First, the low intensity exercise affected to reduce the concentration of the leptin, but there was no difference depending on the exercise intensity difference. Second, the low intensity exercise affected to reduce the amount of the visceral fat, but showed no difference by the each exercise intensity. As the result of this study, the aerobic exercise affects to reduce the amount of leptin and visceral fat, but no showing the difference from the exercise intensity. As like a previous research, it is considered that aerobic exercises made the leptin which secrets from the adipose tissue and is the hypothalamic conveyance activate to affect the amount of visceral fat. When consuming the same amount of the calorie, the low intensity exercise showed better effect to resolve the f at, so the study was going to suggest the solution of the effective exercise intensity for the obesity, but we could not suggest the clear exercise intensity because of various hormones’ change factors, taking nutrition, calorie consumption differences by the each group.

The development of this study was to compare the relationship between physical characteristics, physical fitness and %body. fat use the data from senior students at a girl`s junior high school in 1994 and in 1997. The subjects of this study were junior high school girl`s in kyung pock and were composed of 30 persons in 1994 and 30 in 1997. Their heights, weights, record on the physical fitness and %body fat were measurded. The result of this study as follows: 1. Analysis of t-test revealed that there was a significant difference in height between two groups (p$lt;.001), the mean value of height in 1997 being taller (3.31Cm) than that in 1994. 2. Analysis of t-test revealed that there was a significant difference in height between two groups (p$lt;.001), the mean value of two groups in 1997 being heavier (4.02Kg) than that in 11994. 3. The comparision of %body fat showed that the mean value in 1997 was larger than that in 1994.(22.56% vs 17.95%, p$lt;.001) also, the Comparision of Lean, normal, obese in body type showed that the mean value in 1997 was 30.0%, 63.3% and 6.7%. However, The comparision of Lean body type showed that the mean value in 1997 was decreased than that in 1994. (30.0% vs 16.7%) but the comparision of normal and obese body type showed that the mean value in 199 were increased than that in 1994. (each 63.3% vs 70.0%, 6.7% vs 13.3%) 4. The result of physical fitness test was that the mean value in 1997 was slower than that in 1994. (18.14sec vs 18.36sec) and the record of sit-up was decreased from in 1994 to in 1997. (36.73times/min vs 32.51times/min) also, the record of long distance run was decline from in 1999 to in 1997. (4` 12$quot; vs 4` 15$quot;)

‘Corporate citizenship’ is an appropriate management model in a business environment where ESG issues are rapidly rising, as a company not only pursues economic profits, but also contributes to creating a better world by participating in solving social problems as a member of the social community. In order to respond to the business environment that demands more roles from companies and to acquire competitive strength, many companies are trying to learn the cases of the leading companies. This process of securing competitiveness through mutual organizational learning is called the Red Queen effect. The POSCO Group has been preemptively responding to ESG issues by declaring corporate citizenship as its management philosophy, giving it sufficient competitiveness as a leading company in consideration of the Red Queen effect. Accordingly, we intend to provide theoretical and practical implications for many companies that want to respond to ESG by analyzing the case of POSCOs corporate citizenship promotion and the mechanism that made it possible.

This study was carried out to examine the effects of difference of exercise intensity on immune function and physical fitness by dividing female oldster with over 50-year-old into three groups which are low intensity exercise group of 50~60% maximal heart rate, high intensity exercise group of 70~80% maximal heart rate, and control group, and by making them to exercise aquarobics for 12 weeks. Also, it was implemented to provide effective intensity of exercise and health improvement of hypertensive patients. The results of this study are as follow. Leukocyte count among immune material presented significantincrease in the high intensity exercise group and numerically increased in the low intensity exercise group. CD3 and CD4 were numerically increased in the high intensity exercise group. CD8 and NK-Cell was numerically decreased in the high intensity exercise group, however it was numerically increased in the low intensity exercise group. Immunoglobulin IgA was significantly increased in both low and high intensity exercise group after exercise program. IgG and IgM were significantly increased in the low intensity exercise group

인적자원관리와 기업성과와의 관계에 있어 지식공유의 조절효과 분석

김재구(Jae-Gu Kim),장용선(Yang-Sun Chang) 한국인사관리학회 2004 조직과 인사관리연구 Vol.28 No.2

최근의 기업환경은 지식정보화 사회로 빠르게 진행되고 있다. 이에 따라서 기업에서 지식근로자의 양성과 지식의 확산이 경쟁력 제고를 위한 주요 과제가 되고 있다. 조직에서 지식근로 자의 양성을 위해서는 인적자원관리 시스템이 중요한 역할을 하고, 종업원들 사이의 지식의 확산을 위해서는 지식공유가 중요한 조건이다. 즉 기업이 인적자원관리 시스템을 통하여 지식근로자를 양성하여 성과를 높이기 위해서는 지식공유가 중요한 상황요인이 될 것이다. 따라서 지식공유를 인적자원관리 시스템과 기업성과 사이의 조절변수로서 설정하였다. 지식집약 서비스 산업을 대상으로 한 회귀분석 결과 인적자원관리 시스템의 기업성과에의 영향에 대한 유의성은 입증되지 않았으나, 인적자원관리 시스템과 지식공유의 기업성과에의 상호작용 효과는 유의성 이 중명되었다. 따라서 지식집약 서비스 산업의 기업들은 지식근로자를 양성할 수 있는 인적자원관리 시스템과 함께 종업원들의 지식공유를 확산시킬 수 있는 방안을 동시에 고려하여야 할 것이다. Recently, company's environment is rapidly proceeding to knowledge information society. According to this trend, knowledge worker cultivation has become important task in the knowledge intensive service industrial organizations. Human resource management system in the organization can playa important role in cultivating knowledge workers. HRM practices dimensions appropriate for knowledge worker cultivation are selection, training, performance appraisal, incentive compensation, team work organization, information sharing. These practices can be categorized with three components of skill formation, motivation, employee participation opportunity. Firms have to induce organizational knowledge expansion as they cultivate knowledge worker through human resource management system and they enhance organizational member's knowledge sharing. Regression analysis results from only HRM system in knowledge intensive service industry firms were not significantly related to corporate performance. But our findings show that HRM systems aligned with knowledge sharing can positively influence corporate performance. Knowledge sharing moderates the relationship between HRM systems and corporate performance. Accordingly, knowledge intensive service industrial firms must consider concurrently HRM and knowledge sharing for the corporate performance.
