Purpose: The purpose of this study is to identify the health promoting lifestyle of Korean immigrants and to develop the health promotion program for Korean immigrants. Method: The subject of the study were 207 adults chosen from Korean religious organizations located in Chicago area. The instrument used in this study was Health Promoting Lifestyle Profile (HPLP) by Walker. Sechrist & Pender(l995). The data were collected between August 1 and October 20. 2000 by using self-administered questionnaire. Analysis of data was done by using descriptive statistics. Pearson correlation coefficient, t-test, ANOVA. Duncan test and stepwise multiple regression with SPSS program. Result. 1) The average score of performance in the health promoting lifestyle 2.43 scores. In the subscales, the highest degree of performance was 'spiritual growth', following 'nutrition', 'interpersonal relationship', 'stress management' and 'health responsibility' and the lowest degree of performance was 'physical activity'. 2) Health promoting lifestyle was significantly correlated with such demographic variables as age (F=2.659. p=.049), family income(F=4.696. p = .027), subjective health status(F = 3.882. p=.005), the frequency of pray(F=9.442. p = .000), the frequency of reading the bible(F=8.584. p= .000) and years of residence in the US(F=4.273. p= .015). 3) Health promoting lifestyle was significantly predicted by the frequency of pray, subjective health status. current working status, taking medication, level of education and family income. These variables explained 27.4% of variance of health promoting lifestyle. Conclusion The above findings indicate that it is necessary to develop a health promotion program facilitating exercise and enhancing health responsibility for Korean immigrants. It is suggested that the comparative study to identify the differences and similarities between Korean immigrants in the U.S.A. and Korean residents in Korea.

Polyclonal antibodies labeled with a tracer have been commonly used as secondary antibodies in immunochemical assays to quantify the concentration of antibody-antigen complexes. The majority of these antibodies conjugated with a tracer are commercially available, with the exception of few untouched targets. This study focused on the production and application of mouse anti-quail IgY as an intermediate antibody to link between quail egg yolk IgY and goat anti-mouse IgG-HRP as primary and secondary antibodies, respectively. Subsequently, the produced mouse anti-quail IgY was labeled with horseradish peroxidase (HRP) and its efficiency on enzyme linked immunosorbent assay (ELISA) was compared with that of commercial rabbit anti-chicken IgY-HRP. As an intermediate antibody, mouse anti-quail IgY was successfully produced with good affinity and sensitivity (1:10,000) to the primary and secondary antibodies. Subsequently, mouse anti-quail IgY was effectively conjugated with HRP enzyme, resulting in a secondary antibody with good sensitivity (1:10,000) to quail anti-V. parahaemolyticus and V. vulnificus IgY. The detection limit was $10^5$ CFU/ml for both V. parahaemolyticus and V. vulnificus. The efficiency of the produced conjugate to detect quail IgY on ELISA was comparable to that of the commercial rabbit anti-chicken IgY-HRP, and hence the produced and labeled mouse anti-quail IgY-HRP can be used as a secondary antibody to detect any antibody produced in quail.

The inhibitory effect of IgY against Vibrio parahaemolyticus and Vibrio vulnificus responsible for seafood-borne diseases was investigated in this study. Water-soluble fractions (WSF) of protein containing IgYs were isolated from the egg yolk of hens initially immunized with formalin-inactivated V. parahaemolyticus or V. vulnificus. Protein, total and specific IgY contents of the WSF were determined. The inhibitory and protective effects of IgYs on the growth of V. parahaemolyticus and V. vulnificus were assayed in liquid medium and in mice. IgYs showed high affinity to their corresponding antigens with high titer from day 28 onwards. Protein contents and total IgY concentrations remained stable throughout the immunization period, whereas specific IgY concentrations increased steadily and reached a plateau at day 49. Specific IgY powder (150 mg/ml) significantly inhibited further multiplication of both V. parahaemolyticus and V. vulnificus in liquid medium as compared with the control IgY. The bacteria count in mice feces was lower in mice pretreated with specific IgYs than in those pretreated with PBS or control IgY. Higher survival of mice was observed in the experimental groups pretreated with either anti-V. parahaemolyticus (75% survival) or anti-V. vulnificus (87% survival) IgYs, compared with those in the control groups pretreated with PBS or nonspecific IgY. All mice in the control groups died within three days after bacteria inoculation; hence, the protective effect of specific IgYs against infection caused by V. parahaemolyticus and V. vulnificus was demonstrated.

[Purpose] Weight loss can reduce obesity-induced arterial stiffening that is attributed to decreased inflammation. Angiopoietin-like protein 2 (ANGPTL2) is a pro-inflammatory adipokine that is upregulated in obesity and is important in the progression of atherosclerosis and cardiovascular disease. The purpose of this study is to investigate the effects of dietary modification on circulating ANGPTL2 levels and arterial stiffness in overweight and obese men. [Methods] Twenty-two overweight and obese men (with mean age of 56 ± 2 years and body mass index of 28.6 ± 2.6 kg/m²) completed a 12-week dietary modification program. We measured the arterial compliance and β-stiffness index (as the indices of arterial stiffness) and serum ANGPTL2 levels before and after the program. [Results] After the 12-week dietary modification, body mass and daily energy intake were significantly reduced. Arterial compliance was significantly increased and β-stiffness index was significantly decreased after the 12-week dietary modification program. Serum ANGPTL2 levels were significantly decreased. Also, the changes in arterial compliance were negatively correlated with the changes in serum ANGPTL2 levels, whereas the changes in β-stiffness index were positively correlated with the changes in serum ANGPTL2 levels. [Conclusion] These results suggest that the decrease in circulating ANGPTL2 levels can be attributed to the dietary modification-induced reduction of arterial stiffness in overweight and obese men.

Although healthy lifestyles have been proved as an effective way of improving higher well-beings for individuals. researches on health-promoting behaviors of minority elderly with a specific ethnic heritage have been sparsely tried. This study was designed to explore health-promoting lifestyle patterns of Korean immigrant elderly living in Seattle, USA and its relationships with two associated perceptual variables, self-esteem and perceived health status. One hundred ten Korean immigrant elderly were recruited from two senior centers and interviewed with a structured questionnaire. Data were collected from October 1998 to January 1999, and analyzed using SPSS program through which t-test, ANOVA, and Pearson Correlation Coefficients were tested. As the results, the mean HPLP score of the Korean immigrant elderly was 2.54 (SD ＝ .36), showing significant differences by education (F ＝ 3.61, P ＝ .016), economic status (F ＝ 3.01, P ＝ .034), and current health status (F ＝ 3.69, p ＝ .008). In self-esteem, two socioeconomic variables showed statistical association with self-esteem : marital status (t ＝ 2.47, P ＝ .015) and living situation (F ＝ 4.03, p ＝ .021). The HPLP subscales that showed higher mean scores were nutrition (M ＝ 3.01, SD ＝ .52) and interpersonal support (M ＝ 2.65, SD ＝ .47) while lower mean scores were detected in the domain of exercise (M ＝ 1.92, SD ＝ .74) and stress management (M ＝ 2.26, SD ＝ .47). Perceived health status revealed significant positive correlation with health-promoting lifestyle patterns (r ＝ .19, P ＝ .043) and self-esteem (r ＝ .32, P ＝ .001) in the present study. It is concluded that engagement in health-promoting lifestyle patterns should be actively encouraged to enhance personal health of Korean immigrant elderly. Developing health promotion programs focused on exercise and stress management is also imperatively suggested not only for better health practices of Korean immigrant elderly population but also for enhancing their level of well-beings and life satisfaction.

This study was designed to explore health promoting lifestyle patterns (HPLP) and self-care activities and identify related variables of patients with rheumatic disease. One hundred fifty rheumatic patients were recruited from two university based rheumatic centers according to selection criteria. Collected data were analyzed using SAS program through which with a structured questionnaire. T-test. ANOVA, and Pearson correlation coefficients were tested. The results were as follows: 1. The mean HPLP score of the subjects was 2.71, showed significant differences with economic condition and educational level. The better economic condition and more educated, showed the higher HPLP score. 2. They showed the highest practices in nutrition(mean score=3.11), and the lowest practices in exercise(mean score = 1.99). 3. The mean self-care activity score of the subjects was 3.36, showed significant differences with economic condition and educational level. The better economic condition and more educated, showed the higher self-care activity score. 4. The HPLP score of the subjects showed positive correlations with self-care activity score(r= .66). Developing health promotion programs focused on exercise and stress management is recommended not only for better health practices of patients with rheumatic disease but also for enhancing their level of well-being and life satisfaction.

The purpose of this study was to investigate the eating behavior and life habits of kindergarten children 5 to 7 years old in Chuncheon area. This study was conducted in December, 1996. Anthropometric indices(height, weight, skinfold thickness, mid-arm circumference) were measured and body mass index(BMI), Rohrer index, arm fat area were calculated to estimate children’s body fatness. Also the eating behavior and life habits were determined tv using questionnaire method. The results were as follows: Body fat rate of the children was almost normal according to Rohrer index and BMI. There was significant difference in birth weight between male and female. The problems of the eating behavior were frequent skipping breakfast and eating-out. The rate of the children who took snacks 2 times a day was 46.9％. Most children tended to take sweet snacks such as ice-cream, chocolates, cookies, and they tended to prefer meats and fishes to vegetables. The rate of breast feeding was 28.3％ and the rate of weaning foods prepared at home was 61.1%. Many children preferred indoor activities such as watching TV, toy furniture play, building block to outdoor activities such as roller-skating, cycling, jogging in their spare time. The rate of the children who took exercise regularly was 15％. Children tended to eat kimbap, fried chicken, ramyeon more frequently in various instant foods. The intake rates of fruit juice and barly tea were relatively high and children's favorite fruits were watermelon and mandarin orange. From this results, skipping breakfast, frequent eating-out and the monotony of food preference appears to cause imbalance in nutrient intakes of the children and to have bad influence on children’s health. Accodgingiy, the comprehensive nutrition education and proper modification program should be needed for the children and their parents to correct the eating behavior and life habits. The reasonable exercise programs are needed to motivate outdoor activities of the children, and the importance of breast feeding and weaning foods should be emphasized to lactating women and pregnant women.
