This study was designed to investigate the effects of dietary calcium. serum estrogen level and physical activity on the bone status of 116 healthy elderly women living in urban area. Current calcium intake was assessed by convenient method(refered to as Ca intake) and calcium containing food frequency method(refered to as Ca index) Daily activity record was used for the estimation of physical activity level, and serum estrogen level was measured from fasting blood of subjects. The rate of bone resorption was evaluated by the determination of hydroxyproline(Hpr) in fasting urine with correction for creatinine excretion. The results of this study are summarized as follows : 1) Average daily Ca intake of subjects was 621.4$\pm$155.8mg, which is above the Korean recommended dietary allowances. However 44.8% of the subjects consumed Ca below RDA level. Ca index score was significantly correlated with the bone status(P<0.05), Ca intake did not show significant correlation with the bone status although a positive trend of influence was evident. 2) Average serum estrogen level of subjects was 18.7$\pm$9.8pg Contrary to our anticipation. estrogen level did not show any significant relation to age and bone status. 3) Daily physical activity was classified into four categories by activity intensity : sedentary. moderate, active and severe. The average physical activity of subjects belong to moderate level. and the bone status was significantly related to the physical activity(P<0.01) 4) Among other influential factors such as age, pocket-money. family type. drinking, smoking and BMI, there was a significant difference between bone status and BMI(P<0.05). 5) Multiple regression analysis of variables showed that physical activity has greater effect than other variables when the entire subjects were taken into account. However. eliminating the subjects whose bone status rated as excellent(Hpr/cr<0.009), Ca index showed higher correlation than physical activity. These results have demonstrated that dietary calcium intake is the primary important factor for keeping good bone health and that bone status of subjects with a sufficient calcium intake is affected by various factors such as physical activity, age, smoking. BMI and others.

An investigation was conducted on the enhancement of production and purification of an oxidant and SDS-stable alkaline protease (BHAP) secreted by an alkalophilic Bacillus horikoshii, which was screened from the body fluid of a unique Korean polychaeta (Periserrula leucophryna) living in the tidal mud flats of Kwangwha Island in the Korean West Sea. A prominent effect on BHAP production was obtained by adding 2% maltose, 1% sodium citrate, 0.8% NaCl, and 0.6% sodium carbonate to the culturing medium. The optimal medium for BHAP production contained (g/l) SBM, 15; casein, 10; $K_2HPO_4$, 2; $KH_2PO_4$, 2; maltose, 20; sodium citrate, 10; $MgSO_4$, 0.06; NaCl, 8; and $Na_2CO_3$, 6. A protease yield of approximately 56,000 U/ml was achieved using the optimized medium, which is an increase of approximately 5.5-fold compared with the previous optimization (10,050 U/ml). The BHAP was homogenously purified 34-fold with an overall recovery of 34% and a specific activity of 223,090 U/mg protein using adsorption with Diaion HPA75, hydrophobic interaction chromatography (HIC) on Phenyl-Sepharose, and ion-exchange chromatography on a DEAE- and CM-Sepharose column. The purified BHAP was determined a homogeneous by SDS-PAGE, with an apparent molecular mass of 28 kDa, and it showed extreme stability towards organic solvents, SDS, and oxidizing agents. The $K_m$ and $k_{cat}$ values were 78.7 ${\mu}M$ and $217.4s^{-1}$ for N-succinyl-Ala-Ala-Pro-Phe-pNA at $37^{\circ}C$ and pH 9, respectively. The inhibition profile exhibited by PMSF suggested that the protease from B. horikoshii belongs to the family of serine proteases. The BHAP, which showed high stability against SDS and $H_2O_2$, has significance for industrial application, such as additives in detergent and feed industries.

Background: Cigarette smoking is as the leading cause of cancer mortality and other chronic diseases in males worldwide. The prevalence of cigarette smoking is different across and within countries by age, education level, occupation, and so on. This study aimed to determine the prevalence of cigarette smoking and its relationship with individuals' demographic factors and BMI in adolescent men living in Tehran, Iran. Materials and Methods: This study involved secondary analysis of the 'Urban Health Equity Assessment and Response Tool-2' survey conducted in Tehran, Iran, among men aged 20+, 2011-2012. Using a multistage sampling method, 45,990 men were included in the study. The cigarette smoking status, BMI and demographic factors measured through a self-administered questionnaire. Chi-square, t-test, and logistic regression model were used to examine the relationships between the independents variables and cigarette smoking behavior, using SPSS software version 21. Results: In the total of 45,990 men, the overall prevalence of cigarette smoking was 14.6% (CI 95%: 14.29-14.94). Age (OR=0.96; CI 95%:0.94-0.98), house ownership (OR=0.68; CI 95%: 0.64-0.72), job status (OR=0.60; CI 95%: 0.46-0.86), marital status (OR=0.42; CI 95%: 0.39-0.47) and educational levels (OR=0.50; CI95%: 0.45-0.54) were associated with the prevalence of cigarette smoking. However, associations with BMI, family size, residency years, and district were not statistically significant. Conclusions: Given the relatively high prevalence of cigarette smoking in the study population, policy interventions are required to address this major public health issue, with a focus on the population demographic influences.

Objectives : To survey college students with an Alcohol Use Disorder, and analyze the reasons for their disorder. Methods : The cross-sectional study was conducted at 60 four-year colleges within Seoul and 9 other provinces. The schools and students selected for the study provide a nationally representative sample, and the survey was conducted between May 15th and June 14th 2003. 2,385 cases were analyzed using questionnaires, which included a series of questions about students' alcohol use and associated problems, as well as an Alcohol Use Disorder Identification Test. Results : 42.3% of students were found to have an Alcohol Use Disorder. The probability of a student having an Alcohol Use Disorder was 1.30 times higher among male compared to female students. Those students not living with their parents or relatives were 1.40 times more likely to have an Alcohol Use Disorder. Those students where the father had a drinking problem and those who admitted that their parents drank heavily while they were growing up were 1.38 and 1.54 times more likely, respectively, to have an Alcohol Use Disorder. Those students attending a general university, joining a student club, attaining less than a B average credit score and those unsatisfied with their education were 1.60, 1.36, 1.41 and 1.27 times more likely, respectively, to have an Alcohol Use Disorder. Those students who had experience of drugs, smoking, binge drinking when they were in the last year of high school and the forceful consumption of mixed alcohol were 3.67, 1.95, 2.15 and 1.76 times more likely, respectively, to have an Alcohol Use Disorder. Conclusions : College students' with an Alcohol Use Disorder is a very severe and large problem within colleges. An Alcohol Use Disorder is determined by individual and family variables, the college environmental and life variables, as well as behavior variables.

Purpose: The purpose of this study was to develop a prediction model for the characteristics of older adults with depression using the decision tree method. Methods: A large dataset from the 2008 Korean Elderly Survey was used and data of 14,970 elderly people were analyzed. Target variable was depression and 53 input variables were general characteristics, family & social relationship, economic status, health status, health behavior, functional status, leisure & social activity, quality of life, and living environment. Data were analyzed by decision tree analysis, a data mining technique using SPSS Window 19.0 and Clementine 12.0 programs. Results: The decision trees were classified into five different rules to define the characteristics of older adults with depression. Classification & Regression Tree (C&RT) showed the best prediction with an accuracy of 80.81% among data mining models. Factors in the rules were life satisfaction, nutritional status, daily activity difficulty due to pain, functional limitation for basic or instrumental daily activities, number of chronic diseases and daily activity difficulty due to disease. Conclusion: The different rules classified by the decision tree model in this study should contribute as baseline data for discovering informative knowledge and developing interventions tailored to these individual characteristics.

Objectives: The purpose of this study was to identify the stages of change distributions for nine major health behaviors among poor children in underserved area, and to provide basic information for developing specific objectives and strategies for health education program. Methods: The health behavior data were obtained with a self-administered questionnaire and analysed for 3,081 poor children in 106 local children's centers nationwide. Stages of change classification were based on self-reported responses to five statements. The health behaviors included were balanced diet, safety behavior (helmet and protective device use while riding), regular exercise, smoking, alcohol use, drug use, sleep pattern, weight management and stress management. Results: Poor children were more likely in precontemplation and less frequently in action and maintenance stages for a safety behavior. 33.1% of respondents were precontemplators, 29.9% contemplators, and 6.5% in preparation stage. Only 4.3% and 9.6% were in action and maintenance stages, respectively. Gender differences were apparent. Boys were more likely to be precontemplators for nine health behaviors. Children from the lowest socioeconomic status and disrupted family were more likely to be in precontemplation for weight management and exercise behaviors. Children living with both parents were more likely to be in the action and maintenance stages for nine health behaviors. Stages of change for balanced diet and smoking were significantly related with those for other eight health behaviors. And the stage of exercise adoption was found to be significantly related with those for other seven health behaviors. Conclusion: Safety education must receive high priority in health education program for low income children. Balanced diet smoking cessation and regular exercise could be a possible gateway behavior toward healthier lifestyle practices.

이 연구는 기혼여성의 경제적 의존 수준을 국가 비교를 통해 분석함으로써, 그동안 많은 복지국가 및 소득불평등 연구에서 간과해 온 가족 내(within a family) 불균등한 권력관계를 검토하였다. 기혼여성의 경제적 의존은 가구 내에서, 그리고 전체 사회 내에서 여성들이 열악한 지위에 놓여 있게 하는 원인으로 작용한다. 가족 내 부부의 소득의 비중을 이용한 Sørensen & McLanahan(1987)의 의존 지수(Dependency Index)를 OECD 16개 국가에 대해 도출하였다. 분석 자료는 가구 내 남편과 부인 각각의 소득에 관한 정보를 제공하는 룩셈부르크 소득조사(LIS) Wave V(2000년 전후 시점)이다. 이 지수는 노동시장 참여여부, 노동시간, 임금수준을 종합적으로 고려하였다. 의존 지수는 배우자 중 한 명이 노동시장에 참여하지 않는 경우를 포함한 모든 부부를 대상으로 했을 때와 맞벌이 부부만을 포함했을 때로 구분하여 도출하였다. 분석 결과, 모든 부부를 대상으로 했을 때 의존 지수값은 스칸디나비아 국가들이 가장 낮게 나타났다. 이는 이들 국가의 높은 경제활동 참가율에 기인한다고 할 수 있다. 7세 미만 자녀가 있을 경우 기혼여성의 경제적 의존 상황은 더욱 악화되는데, 국가마다 상당한 정도의 차이가 존재하는 것으로 나타났다. 맞벌이 부부를 대상으로 한 의존 지수값의 경우, 앞의 결과와 비교하여 대부분의 국가에서 의존 지수값이 작아졌고 국가 간 편차가 다소 줄어들었다. 여성 파트타임 고용률이 높은 국가들의 경우, 여전히 의존 수준이 높게 나타나 기혼여성의 노동시장 참여가 반드시 맞벌이 가구에서의 경제적 권력관계를 변화시키는 것은 아님을 보여주었다. 마지막으로, 기혼여성의 경제적 독립수준이 높아지는데 필요한 정치 경제 제도적 조건에 대한 분석을 실시하였다. Ragin(2000)의 퍼지셋 질적비교분석(FSQCA)방법을 사용하여 필요충분조건 분석을 실시한 결과, 강력한 노동운동의 영향력, 높은 수준의 공공 부문 고용창출, 관대한 가족지원 조건이 기혼여성의 경제적 독립성에 필요한 조건임이 검증되었다.

The purpose of this study was to identify and construct a substantive theory about the experience of fatigue among the female elderly with osteoarthritis. The interviewees were 6 female elderly with osteoarthritis. Of them 3 were admitted General hospital, the remaining 3 didn't admitted hospital. The data were collected through in-depth interviews by the investigators from May 20th, 1995 to June 19th, 1995. The collected data were coded into concepts and categories according to Strauss & Corbin's grounded method. The data thus collected were analyzed immediatly after interviews and fed into next round of interviews until the data collection reaches the saturation point where no additional concepts emerge. The 35 concepts were from analyzing the grounded data. The results of this study were as follows : 'change of the health condition','change of the life pattern', 'physiologic change', 'change of the coping pattern', 'performance of homework', 'activity daily living', 'tireness', 'ache', 'change of general apperance', 'sleep disturbance', 'powerlessness'. 'Physiologic unbalance', 'change of the family dynamics', 'physical imbalance', 'loss of the control', aviodance', 'conversion', 'leaving', 'indifference', 'hesitation', 'the pursue of information and trial', 'the western therapy', 'heat therapy', 'the oriental therapy','exercise', 'weight control', 'support', 'solution', 'being as before', 'adding more'. Six categories emerged from the analysis of ground data. They were as follows : 'stimuli', 'fatigue', 'passive coping', 'active coping', 'disolution', 'remains'. 13 hypothesis were derived from the integration of categories as follows : 1. The stronger the stimulus as perceived by the subjects, the more the fatigue will exrerience. 2. The more severe the fatigue, the more severe the tireness. 3. The more severe the fatigue, the more the hardness. 4. The more severe the fatigue, the more the variability of appear will experience. 5. The more severe the fatigue, the more the pain will experience. 6. The more severe the fatigue, the more the insomnia will experience. 7. The more severe the fatigue, the more the powerless will experience. 8 The more severe the fatigue, the more the psychological unbalance will experience. 9. The more severe the fatigue, the more variability of the family dynamics will experience. 10. The more severe the fatigue, the more the physical unbalance will experience. 11. The more severe the fatigue, the more loss of control will experience. 12. The subjects who experienced the fatigue will be to show passive coping and active coping mechanism.
