Differences in dietary intake of Korean Americans (KA) by the length of residence in the U.S. were studied in relation to health and disease patterns in Michigan. Of 1860 questionnaires mailed, 637 (34.3%) responded with demographics, anthropometrics, self-reported disease patterns, lifestyle, and dietary patterns (93-item FFQ developed for KA). Complete responses were available for 498 people (263 men,253 women, aged 30-87 yr), who were then divided into three groups based on the number of years lived in the U.S.: 15y, 16-25y, 26y. Age-adjusted weight, height, BMI, and waist to hip ratio were within the normal ranges and did not differ among the three groups. Chronic diseases frequently reported in men and women (age-adjusted) included hypertension (14.4%, 14.1%), digestive diseases (5.4%, 8.5%), diabetes (3.6%,4.9%), and arthritis(3.3%, 12.5%), respectively. The length of residence in the U.S. was inversely associated with the age-adjusted prevalence of digestive diseases (12.4%, 6.5%, 0.4% in men, 13.0%, 11.7%, 0% in women). The length of residence was positively associated with health consciousness, receiving regular health care, taking supplements regularly, and exercising, while inversely related to smoking. The majority favored American foods for breakfast and Korean foods for dinner. Foods frequently consumed included cooked rice (w/other grains). kimchi, coffee (w/cream and sugar),bread (white and dark), citrus juice, milk (low fat and skim), lettuce and cucumber, apple, seaweed, and soda. Intake frequency of the Korean starch food group was inversely associated with the length of residence for both men and women (p<0.001), but not with the American starch food group. Fat intake did not differ by the length of residence in the U.S. The dietary changes were associated with the length of residence and chronic disease patterns for the first generation of KA, which should be further examined 'for the subsequent generation of KA.

This study was conducted with 512 students in 4 primary schools located at the inner and the outskirt of K city, Northern Kyungsang Province from November 6, 2001 to November 27, 2001(during 3 weeks). This study was a research about the difference of a bullying degree and tendency of both teasing and teased students. The purpose of the study was to help nursing teachers in charge of student consultation and treatment. The findings are as follows: First, for to whom students confess their worries, students in lower grade talked to their parents while students in higher grade talked to their close friends. The higher grader, the higher rate in solving their problems by themselves. For how many students are teased by their peers in groups, 52.0％ students answered 1 or 2 students in a class. For the reasons of bully, 37.0％ higher graders answered, very selfish and putting on airs after 29.6％ lower graders answered, ugly and bad at speaking. Second, for perception of peer relation, 81.3％ students participating in the study answered, very important. For a question whether students satisfy present relation with their friends by gender, 53.7％ boys were satisfied while 34.6％ girls were satisfied. Third, for difference in bullying by gender, boys mainly teased others by using words and physical power(p<0.000) while girls estranged others. When it goes to teased students, it was the case: boys were bullied physically(p<0.000) and linguistically while girls were hurt by estrangement. Having nothing direct to do with school achievement, nursing teacher should make good use of such an advantage that students tend to easily confess their worries to them and take care of psychological aspects of students in treatment. Furthermore, it needs to include contents of bully in the regular heath care education.

Objectives: The purpose of this study was to provide a basic data of nutrition services in home health care by analyzing hospital-based home-visit nutrition education needs of patients at discharge. Methods: Data was collected from September 11 to October 12, 2012 by administering questionnaires to 289 chronic disease patients to be discharged from a university hospital in Pusan. The home-visit nutrition education instruments used for collecting data were developed by the researcher. Results: Regarding the demands of home-visit nutrition education, 62.3% of subjects were willing to use home-visit nutrition education and 37.7% weren't. The main reason for using the home-visit nutrition education was "the effective nutrient management in consultation with an individual's doctor", 38.9% and 31.2% of patients who did not wish to use the service gave the reason for their decision as, "Just by managing the nutritional requirements of a family's diet and, the patient will be able to fully recover", respectively. As for the demand, classified with the areas of home-visit nutrition education, the demand for the area of basic nutrition (3.75/5.00) was the highest followed by, the area of educational nutrition (3.74/5.00), therapeutic nutrition (3.67/5.00), and dietary nutrition (3.55/5.00). The demand for the area of educational nutrition was high "Considering the state of dietary management, such as disease status and drugs", 73.7%. As for the relation between the characteristics of the study subjects and analysis of demand home-visit nutrition education, the characteristic of subjects, that is, "regular home-visit nutrition education", "practice of diet therapy after discharge" had a significant difference statistically (p < 0.01). As for the relation between the needs for fundamental home-visit nutrition education and the demand of home-visit nutrition education, basic nutrition, educational nutrition, therapeutic nutrition, and dietary nutrition had a significant difference statistically (p < 0.01).

호텔은 인적자원의존도가 대단히 높은 기업이다. 종사원의 고용불안은 숙련된 종사원의 이직불안으로 연결된다. 경영환경이 복잡하고 불확실할수록 조직을 유지 발전시키기 위해서는 호텔기업이 종사원으로부터 신뢰를 얻어야 하며, 조직에 대한 종사원의 신뢰 역시 중요하다. 본 연구는 관광기업 중에서도 고용불안인식이 비교적 높은 특급호텔 식음료업장 종사원의 고용불안인식과 조직 내 신뢰수준을 확인하고 고용불안이 신뢰에 미치는 영향측정을 연구목적으로 한다. 고용불안은 신뢰에 부정적인 영향을 미칠 것이라는 가설 검증결과에서 고용불안이 동료신뢰와 회사신뢰에는 유의한 영향을 미치지 못하는 것으로 나타났다. 단지 해고위험요인만이 상사신뢰에 유의한 영향을 미치는 것으로 나타났다. 즉, 해고위험이 있다고 하더라도 동료와의 신뢰에는 아무런 상관이 없다고 볼 수 있으며, 회사신뢰의 경우도 회사는 해고의 결정권자로서 해고의 직접적인 원인으로 보지는 않는다고 여겨진다. 다만 회사직원들은 해고위험과 관련하여 직접 현장에서 같이 근무하는 직장상사의 근무평가나 관계가 해고로 이어질 수 있다고 여기고 있는 것으로 유추할 수 있을 것이다. 고용불안인식에 대한 비정규직종사원, 정규직 종사원간 차이는 나타나지 않았다.

Correlations among body weight and sociodemographic factors, including life - style were tested as social determinants of health in a sample of 5,201 adults in Korea. The aim of this study was to determine the extent to which sociodemographic variables and life-style associated health behaviors explain body weight distribution. A second aim was to explain the relation of body weight and health status to stress the importance of body weight as an early risk indicator of health status. The canonical correlation between the weight distribution(underweight and overweight) and the independent variables was 0.29, 17% of the total variance was explained. Perceived health level represented the highest contribution(canonical coefficient 0.82) to body weight. Sociodemographic factors such as sex, economic status, and life-style factors such as smoking, exercise, regular meais and sleep showed comparatively high contributions to body weight. The relevance of body weight for health status including the rate of chronic disease and the rate of medical utilization was significant. Especially, underweight was clarified as being mere important than overweight to morbidity level and medical utilization. These findings suggest that perceived body weight is an important indicator of health status and is thus a valuable variable to be considered for nursing intervention and health education related to the promotion of health.

An automatic titration system using a PC-camera with a color filter on its lens was used in the $KMnO_4$ consumption test of tap water and distilled water in relation to blank tests. The very faint pink color of titration end point could be effectively detected by using a yellow cellophane paper as a color filter. The average hue value (Havg) of 192 pixels in the image of the sample solution being titrated was computed and followed up at regular time intervals during titration in order to detect the titration end point. The Havg decrease of 2 degrees from the average of first 10 Havgs was regarded as reaching the end point. The volume of 0.01N $KMnO_4$ consumed by a tap water sample was $0.728{\pm}0.022ml$ in manual titration and $0.735{\pm}0.013ml$ in automatic titration (p=0.580). The volume of 0.01N $KMnO_4$ consumed by a distilled water sample was $0.383{\pm}0.015ml$ in manual titration and $0.367{\pm}0.015ml$ in automatic titration (p=0.252). The high p-values for t-test suggested that there were good agreements between manual and automatic titration data and the automatic method proposed in this article was considered to effectively replace the manual titration.

The research on the price-volume relation in the market is very important because it examines into regular phenomenon revealed by market participants including producers and middlemen. The purpose of this study is to investigate the relationship between price and trading volume in the oyster producing market. In order to accomplish the purpose of this study, the contents of empirical analysis include the time series properties of price and trading volume, the short-term and long-term relationships between price and trading volume, and the determinants of trading volume. The data used in this study correspond to daily price and trading volume covering the time period from January 1998 to April 2001. The empirical results can be summarized as follows : First, price and trading volume follow random walks and they are integrated of order 1. The first difference is necessary for satisfying the stationary conditions. Second, price and trading volume are cointegrated. This long-run relationship is stronger from trading volume to price. Third, error correction model suggests that feedback effect exists in the long-run and that price tends to lead trading volume by about five days in the short run, that is, to be required period by digging, conveying, and peeling oystershell for selling oyster. Fourth, price and price volatility is a determinant of trading volume. In particular, trading volume is a negative function of price. It is believed that the conclusion drawn from this study would provide a useful standard for the policy makers in charge of reducing the oyster price volatility risk caused by trading volume(selling quantities).
