This study was performed to investigate the preference and consumption pattern on milk and milk products of middle and high school students. The subjects were 1,195 students(590 middle school and 605 high school students) living in Geochang area. The survey was conducted by using a self-administered questionnaire in November, 2004. The results were as follows. Sixty-three point four percent of the subjects liked milk, and the main reason was 'accelerate growth and development'(55.4%). Preferred tastes of milk were 'savory taste'(35.4%) and 'sweet taste' (29.9%). Banana milk, chocolate milk, strawberry milk, ice cream, yoplait and yogurt were highly preferred. General preference for different kinds of milk was significantly higher in high school students and male students than in middle school students and female ones. With regard to preference for dairy products, cream (p<0.01) and butter(p<0.05) was preferred more by male students than by female ones, ice cream(p<0.05), yoplait (p<0.05) more by female students than male ones. The score of milk intake frequency was 3.84(3~4 times a week) out of 5 points(7 times a week) for white milk, and that of chocolate milk was 1.98, banana milk 1.96, strawberry milk 1.72, coffee milk 1.65, showing that these products were drank less then once a week. In addition, the white milk intake frequency was significantly higher in middle school students and male students than in high school students and female students(p<0.001). Preference for milk showed a positive correlation with preference for dairy products (r=0.543, P<0.001) and frequency of milk intake(r=0.429, P<0.001). This suggests that those who prefer milk high tend to prefer dairy products and to show high milk intake frequency. In addition, milk intake frequency was in a high positive correlation with dairy product intake frequency(r=0.648, P<0.001).

To identify osteoporosis and examine the relationship between health behavior and the self-efficacy of middle-aged women, a descriptive survey was conducted. The subjects were 465 healthy female residents of Kyunggido, Korea, who underwent ultrasound measurement and a health examination at the Kangmeung-Ci Health Center between July and August 2000. They were 40 to 60 years old, with a mean age of 46.7 years. The subjects completed a self- reported questionnaire that consisted of seven items concerning health behavior and twelve items concerning self-efficacy related to osteoporosis. Bone density was evaluated from ultrasound measurements of the right heel. All the data were analyzed using the program SAS-PC. The study found that the mean T score related to bone density was -1.30, and ranged from -3.52 to 3.06. Based on the T score, 74.8% of the subjects were normal, 12.9% had osteopenia, and 12.3% had osteoporosis. The mean osteoporosis self-efficacy score was 41.17 and ranged from 12 to 60. Osteoporosis self-efficacy differed significantly with health behavior related to health supplementary food (t=5.63, p=.018), exercise (t=6.65, p=.010), alcohol drinking(t=10.80, p=.001), and smoking (t=10.23, p=.001). A community-based health promotion program should be developed to prevent osteoporosis in middle-aged women.

PURPOSE: The purpose of this study was to provide fundamental materials for improving school health promotion programs by investigating school nurses' awareness of the importance, performance level, and perceived competence level of school health promotion programs in Gangwon-do. METHODS: The subjects of this study were 173 school nurses who were working in Gangwon-do. The instrument for this study was a scale for awareness of importance, performance level, and perceived competence level. Data were collected on December 15, 2007 and analyzed using SPSS 13.0 for Windows. RESULTS: The mean score of awareness of importance was 3.51 (range: 1~4). The mean score of performance level and the mean score of perceived competence level were 3.35 (range: 1~4) and 3.29 (range: 1~4), respectively. The younger school nurses were (F=4.380, p=.014), the higher their awareness of importance was. The performance level was lowest in high school nurses (F=5.013, p=.008). There were significant correlations between awareness of importance, performance level, and perceived competence level in school nurses. CONCLUSION: In order to improve the effectiveness of school health promotion programs, training and education programs for school nurses' competencies and technical support systems for school nurses should be provided.

OBJECTIVE: The purpose of this study was to evaluate the effectiveness and limitations of the Risk of Malignancy Index (RMI) for discriminating malignant from benign adnexal masses. METHODS: This study was based on 382 women who have visited Korea University Hospital for surgical exploration of adnexal masses between July 2000 and December 2003. RMI was based on menopausal status, serum CA 125 levels, and ultrasound feature. A cutoff level of 200 was chosen as the threshold for discriminating malignant from benign adnexal masses. This setup was evaluated by sensitivity, specificity, positive predictive (PPV) and negative predictive values (NPV) with respect to the ability to distinguish malignant from benign adnexal masses. RESULTS: The sensitivity was 57.1%, specificity 93.3%, PPV 74.7% and NPV 86.3%. If stage I disease is considered "benign", the sensitivity was 95.1%, specificity 89.3%, PPV 52.7%, and NPV 99.3%. The statistical significance of RMI over other factors was proven. However, it had limitations of high false negative rate (68.4%) in stage 1 ovarian malignancy including borderline malignancy. Moreover, its relationship with RMI1, RMI2, and RMI3 had no statistical significance. CONCLUSION: RMI is a simple, easily applicable method for the primary evaluation of patients with adnexal masses and an effective method to selectively refer to an oncological unit for further management due to its relatively high specificity observed from this study. However this method has significant limitations in stage I ovarian malignancy including borderline malignancy. Other methods should be evaluated to increase the diagnostic accuracy.

PURPOSE: The purpose of this study was to analyze the trend of research on the use of home-based pulmonary rehabilitation. METHOD: Using Medline and CINAHL search engine, experiemental research, titled as 'home-based pulmonary rehabilitation' and 'chronic lung disease', statistics were collected. The total 29 experimental studies published between 1981 to 2000 were selected and analyzed according to the ATS guidelines. RESULT: 1) The study samples in research were mostly of men, whose lung function was moderate to severe. 2) The total period of the intervention program varied from 5 to 12 week. The program included excercise intervention and educational intervention. Psychosocial intervention was minimal. 3) The outcome of the home-based pulmonary rehabilitation had been measured mostly by physical aspects. Quality of life and cost were less frequently measured. 4) In terms of effectiveness of the home based pulmonary rehabilitation program, physiologic outcome, such as lung function and hematologic markers, there was more 'no effect' than 'positive effect', whereas there was more 'positive effect' in decreasing dyspnea, improving excercise capacity, and improving quality of life. CONCLUSION: Based on these findings, future research on home-based pulmonary rehabilitation should be emphasized and provide standardized protocol, including psychosocial intervention, and analyses on cost and quality of life.

This study was aimed at primarily to develop a tool to evaluate sexuality education and secondarily to test effectiveness through application of developed evaluation tools in elementary school. The results from this study were summarized below: 1. On the basis of targeting the lower grades (1st- 3th year) and the higher grades (4th-6th year) elementary school students' sexuality education guidebooks published by Korea Ministry of Education & Human Resources Development, 71 preliminary items targeting the lower grades, 90 preliminary items targeting the higher grades were developed. 2. Through the validity test about the contents of the preliminary items three times, the items were regulated to 65 items targeting the lower grads and 57 items targeting the higher grades. And then, the preliminary items were re-regulated to 40 items separately. Then, pre-test which targeting each 30 students was enforced. 3.Finally, the evaluation tools for sexuality education that consisted of 40 items targeting the lower grades and the higher grades were developed. 4.Reliability test of the developed tools, sexuality education evaluation tools showed alpha coefficient of internal consistency were 0.8355 (for the use of the lower grades) and 0.8881 (for the use of the higher grades). 5.To apply the developed sexuality education evaluation tools, 10-times sexuality education were carried out class unit and pre-post test were done using same questionnaire, which contains developed tool, there were significant difference in low grade (t=16.548, p=0.000), high grade (t=14.773, p=0.000). The results of this study suggest that the evaluation tool for sexuality education in elementary school may be a useful tool with a high degree of reliability and validity. In this sense, the evaluation tool for sexuality education developed by this study can be effectively utilized in Korea elementary schools.

BACKGROUND: The participation of children in clinical research requires parental permission. We designed this study to evaluate the extent to which the risk associated with a clinical study affects the parents' decision to provide permission. Simultaneously, we evaluated factors which led parents to allow or decline their child's participation in such clinical studies. METHODS: We interviewed 82 parents of children of ASA class I-II scheduled to receive general anesthesia for elective surgery. Parents were presented with either of two sham protocols: no risk (Control, n = 44), or pain (Pain, n = 38) and asked to complete a questionnaire detailing the reasons for their decision. RESULTS: There were no differences in the demographics of the two groups. Whereas comprehension of the doctor's explanation was similar in both groups, consenting rates were higher in the control group (54.5% versus 28.7%; P <0.01). The importance of the study was the primary factor in the parents' decision to consent, and the child's safety was the main concern for parents that declined. Only 4.2% of the control group and 3.7% of the risk group reported having felt pressured to consent. CONCLUSIONS: Results of this study show that the contents of study itself is an important factor that influences a parent's decision to consent to a child's participation in clinical studies. Therefore it is important that researchers produce an adequate protocol and a reasonable explanation for obtaining consent, to reduce the potential for selection bias, and to ensure that the legal and ethical rights of patients are protected.

Elderly people comprise an increasing proportion of the population, and nutritional impairments may contribute to health problems among this group. This study was conducted to evaluate the nutritional status by Mini-Nutritional Assessment (MNA) and to identify relationships among anthropometric measurements, biochemical indicators, bone Mineral Density (BMD) and MNA results among older adults (> or =65 yrs, n=98, 66.7+/-2.5 yrs; M=52, F=46, BMI 24.5+/-2.8 kg/m2) at a Health Care Center. A dietitian administered MNA and collected anthropometric measurements (weight, height, waist circumference), biochemical indicators (albumin, hemoglobin, hematocrit, TLC, glucose, lipids) and the BMD (spine, femur, F=46). Subjects were grouped into a normal nutrition group (0~2 risk factors of malnutrition) and a high risk of malnutrition group (>=3 risk factors of malnutrition) based on their risk factor status for malnutrition. The risk factors for malnutrition include age > or =65 years, PIBW <90%, albumin <3.5 g/dl, TLC <1,500%, Hgb <14 g/dl (men), Hgb <10 g/dl (women), loss of appetite and weight loss 1~3 kg/last 3 months. In addition, subjects were grouped into a normal, osteopenia and osteoporosis group by BMD. We found that 12% of the subjects were at risk of malnutrition (MNA score, 21.4+/-2.1) and that 88% were well nourished (27.3+/-1.5) according to the MNA. Full-MNA scores were positively and significantly (p<0.05) associated with BMI, mid-arm circumference (MAC), calf circumference (CC), albumin and hemoglobin, respectively. The full-MNA score of the high risk of malnutrition group (23.0+/-3.8) was lower than that of the normal nutrition group (27.0+/-2.1) (p<0.05). In addition, the Full-MNA score was negatively associated with the risk factor of malnutrition (r=-0.35, p=0.0004). We found that 39.1% of the subjects had osteoporosis, 45.7% had osteopenia and 15.2% were normal according to their BMD. The MNA score of osteoporosis group (24.58+/-3.3) was lower than that of the normal (27.4+/-1.1) and osteopenia group (26.9+/-1.5) (p<0.05). These results suggested that MNA can be useful as a nutritional screening tool of older adults in Health Care Centers.

We previously reported that the extract from cuttlebone (CB) has wound healing effect in burned lesion of rat. In present study, the main component of CB extract was analyzed and its wound healing activity was evaluated by using in vitro acute inflammation model. The extract of CB stimulated macrophages to increase the production of TNF-alpha. The extract also enhanced the production of TGF-beta and VEGF, which were involved in angiogenesis and fibroblast activation. The treatment with CB extract enhanced proliferation of murine fibroblast. CB extract also induced the activation of fibroblast to increase the secretion of matrix metalloproteases 1 (MMP1). The constituent of CB extract which has wound healing activity was identified as chitin by HPLC analysis. The mechanism that the CB extract helps to promote healing of burned lesion is associated with that chitin in CB extracts stimulated wound skins to induce acute inflammation and to promoted cell proliferation and MMP expression in fibroblast. Our results suggest that CB or chitin can be a new candidate material for the treatment of skin wound such as ulcer and burn.
