  • BACKGROUND/OBJECTIVES: The inverse relationships of combined fruits and vegetables intake with blood pressure have been reported. However, whether there are such relationships with salty vegetables has rarely been investigated in epidemiologic studies. We evaluated the relation of combined and separate intake of fruits, vegetable intakes, and salty vegetables, as well as sodium and potassium, with blood pressure among the middle-aged and elderly populations. SUBJECTS/METHODS: The present cross-sectional analysis of a prospective cohort baseline survey was performed with 6,283 subjects (2,443 men and 3,840 women) and free of hypertension, diabetes, cardiovascular diseases, and cancer. Dietary data were collected by trained interviewers using food frequency questionnaire. RESULTS: The significantly inverse linear trend of diastolic blood pressure (DBP) was found in fruits and non-pickled vegetables (81.2 mmHg in the lowest quintile vs 79.0 mmHg in the highest quintile, P for trend = 0.0040) and fruits only (80.9 mmHg in the lowest quintile vs 79.4 mmHg in the highest quintile, P for trend = 0.0430) among men. In contrast, sodium and sodium to potassium ratio were positively related with blood pressure among men (DBP, 78.8 mmHg in the lowest quintile vs 80.6 mmHg in the highest quintile, P for trend = 0.0079 for sodium; DBP, 79.0 mmHg in the lowest quintile vs 80.7 mmHg in the highest quintile, P for trend = 0.0199 and SBP, 123.8 mmHg in the lowest quintile vs 125.9 mmHg in the highest quintile for sodium/potassium). Kimchies consumption was positively related to DBP for men (78.2 mmHg in the lowest quintile vs 80.9 mmHg in the highest quintile for DBP, P for trend = 0.0003). Among women, these relations were not found. CONCLUSION: Fruits and/or non-pickled vegetables may be inversely, but sodium, sodium to potassium, and Kimchies may be positively related to blood pressure among men.

  • Introduction: Breast cancer is the most common cancer among Jordanians. Breast cancer patients suffer from several negative consequences after treatment and these include pain, fatigue, sexual problems, appearance and body image concerns, with psychological dysfunction. This could affect the patient quality of life and psychological well-being. To the best of our knowledge, there is no published quantitative data on the quality of life and psychological well-being of breast cancer patients in Jordan. The objective of this study was to obtain such data and assess predictors with calculated scores. Methods: In this cross-sectional study conducted among breast cancer patients in Jordan diagnosed in 2009 and 2010, assessment was performed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Breast Module (QLQ-BR23) and the Hospital Anxiety and Depression Scale (HADS). Clinical, demographic and psychosocial indicators that could predict patient quality of life scores were collected. Results: The number of patients interviewed was 236 (mean age=$50.7{\pm}10.7$ years). The mean Global Health score for the QLQ-C30 was $63.7{\pm}20.2$ SD. Among functional scales, "social functioning" scored the highest ($mean=78.1{\pm}28.6$ SD), whereas "emotional functioning" scored the lowest ($mean=59.0{\pm}SD\;33.5$). For the QLQ-BR23, the worst scores within the functional scales were for "body image" ($mean=52.1{\pm}36.8$ SD) and "future perspective" ($mean=52.9{\pm}38.5$ SD). The worst symptom was "upset by hair loss" ($mean=69.8{\pm}43.0$). The mean HADS scores was $18.{\pm}9.0$ SD. Out of study participants, 53% scored abnormal on the anxiety scale and 45% on the depression scale. Severe depression and severe anxiety were detected among 8% and 14% of study participants, respectively. Statistically significant predictors for individual scores were similar to those reported in published studies, such as the presence of recurrence since baseline, family history of cancer, low educational status, current social problems, extent of the disease, presence of financial difficulties, and employment status. Conclusions and Recommendations: Breast cancer survivors in Jordan have overall good quality of life scores when compared with patients from Western countries. However, their psychological wellbeing is more impaired. There is an urgent need for psychosocial support programs and psychological screening and consultation for breast cancer patients at hospitals of the Ministry of Health in Jordan.

  • Purpose Targeting Korean companies listed on Korean securities markets (i.e., KOSPI and KOSDAQ markets), this study aims to shed lights the effects of personal information security breaches on stock prices of information security companies. Interestingly, this study is, to the best of our knowledge, the first to examine the information transfer effect on personal information security breaches of companies. Design / Methodology /Approach To examine the information transfer effect of personal information security breaches, our study employs the event study commonly used in financial studies. To this end, we investigate a variety of events of personal information security breaches of companies listed on the KOPSI stock market and the KOSDAQ market. We collect the total samples of one hundred and twelve with forty seven of events of personal information security breaches by thirty companies and sixty five of information security companies. Findings The principal findings from the empirical study are as follows. First, for companies of personal information security breaches, our event study presents the significantly negative AAR (averaged abnormal return) value on the event day at the 5 % level and the highly significant negative CAAR(cumulative averaged abnormal return) value on the event day and the day after the event day at the 1 % level. The results suggest that personal information breaches significantly contribute to an decrease in value of the information breached companies. The cross sectional regressions in this study estimate the significantly negative coefficient for the ME/BE variable, the proxy for a growth opportunity at the 5 % level. This suggests a reverse relation between the growth opportunity of companies and their value. As for the various samples of the information security companies categorized by physical security, network and system security, security application software, code authentication, system integration, we find the significantly positive AAR on the day after the event day at the 5% level, only for the network and system security-companies. This addresses that the information transfer effect followed by personal information breaches is uniquely observable for companies categorized into network and system companies. The regressions for the network and system companies estimate the significantly positive coefficient for the NS dummy variable (i.e., the dummy of the network and system security companies) at the standard level. This allows us to identify appropriate times needed to make the information transfer effect realized from personal information breached companies to information security companies.

  • 이 연구에서는 미국의 북중부 7개주를 대상으로 농촌 주거지 개발에 영향을 미치는 주요 인자들을 분석하였다. 특히, 사회경제적 요인들과 산림유형에 따른 산림환경특성을 주거지 개발의 주요 요인으로 고려하여 상대적 중요도를 살펴보았다. 먼저, 1950년 이후 미 북중부 지역에서 나타난 인구변화에 대한 실증모델을 개발하였고, 고정효과 패널모델을 이용하여 인구변화에 영향을 미치는 주요 인자들을 분석하였다. 연령별로 인구변화패턴과 거주지를 선택하는 선호 요인이 상이하게 나타나기 때문에, 실증모형을 구성할 때 연령별로 모형을 설정하였다. 다음단계로, 인구변화에 영향을 미치는 요인들이 소득과 같은 가변요인 뿐 아니라 단기간에 거의 변화가 없는 지역의 특수한 환경 요인들을 포함할 것이라는 가정하에, 패널모형의 고정효과 값을 종속변수로 설정하여 각 카운티별 인구증감의 차이가 산림환경, 수자원 등 시간불변변수들에 의해 영향을 받는 것으로 설정하여 횡단면적 모델을 추정하였다. 마지막으로, 농촌 지역의 주거지 수요를 설명하는 모델을 추정하였다. 연구결과, 이주자의 나이가 주거지 선정에 영향을 미치는 핵심 인자로 나타났고, 특히 사회경제적 요인 뿐 아니라 산림유형, 수자원 등 환경 어메니티가 주거지 수요에 미치는 상대적 중요도도 나이 계층별로 상이한 것으로 나타났다.

  • This study is a cross-sectional study for conscripts with chronic low back pain, where it is designed to investigate general characteristics that conscripts with chronic low back pain carry, and it is also aimed to analyze the correlation as well as discrepancy within pain, depression and body mass index depending on their ranks. In this study, 90 Korean conscripts with chronic low back pain participated. And in order to analyze general characteristics as well as pain, depression and body mass index of the subjects, this study adopted a survey questionnaire upon general characteristics, and it also employed Visual Analogue Scacle(VAS) and Center for Epidemiological Studies Depression(CES-D) Scale which have proven their credibility, where BMI values for the subjects were calculated based on 'Asian Pacific standard' Body Mass Index(BMI). From the general characteristics exhibited by the subjects through this study, average age and average height of the subjects were $20.78{\pm}1.41$ and $175.97{\pm}5.34$ respectively; and corporals displayed the highest ratio of 42% with the chronic low back pain while 40% of the total subjects experienced the duration of the illness less than 6 to 9 months. Moreover, 57.8% of all subjects were reportedly suffering moderate pain, and 48% exhibited depression while 49% carried BMI value between 18.5 and $22.9kg/m^2$(normal range). Based on the analysis of correlation among pain, depression, discrepancy of BMI depending on the ranks and each independent variable, it appears that there is no significant difference amongst the ranks, and there is no correlation between independent variables; however, it was obvious that all groups divided by the ranks had a moderate pain(45-74mm), depression(${\geq}16$) and BMI value in normal range(18.5-22.9).

  • The aim of this study was to investigate the relationships between eating habits and health among adolescents in Shanghai and Heze, China. A cross-sectional study was conducted in 2013 on 2,089 adolescents; 1,089 students were from Shanghai and 999 students from Heze region. Eating habits, weight, height, and nutritional knowledge were assessed using a self-administered questionnaire. Eating habits score was classified into two categories: healthy eating habits and unhealthy eating habits, based on "Korean Youth Risk Behavior Web-based Survey", for statistical data analysis. Associations between eating habits, BMI, and nutritional knowledge were examined using a general linear model with adjustment of potential confounding factors such as region, gender, age, parents' education level, and pocket money. Statistical analyses were performed using the SAS (version 9.3) program. Proportions of healthy eating habits group were 90.0% for breakfast (3-7 times/wk), 29.1% for fruit (${\geq}once/d$), 12.5% for vegetable (${\geq}3times/d$), 7.3% for milk (${\geq}2times/d$), 90.0% for fast food (<3 times/wk) consumption, respectively. The average BMI score was 20.1 (Shanghai 20.5 Heze 19.6), which is in the range of normal weight. Rates of obesity and overweight were 16.5% and 8.3% in Shanghai and Heze, respectively. There were significant negative correlations between intake frequencies of breakfast, fast food, biscuits, sugar, chocolate, and BMI score. Eating habits and nutritional knowledge score showed a significant positive correlation. These results showed better eating habits regarding eating regularity and consumption of fruits and soft drinks in Chinese adolescents compared with Korean adolescents, although cultural differences were not fully considered. This study demonstrated significant associations of BMI and nutritional knowledge with dietary behavior in Chinese adolescents in two regions of China. Further studies on Chinese adolescents from other regions in China should be considered.

  • Objectives: Mental health disorders and suicide are an important and growing public health concern in Korea. Evidence has shown that both globally and in Korea, obesity is associated with an increased risk of developing some psychiatric disorders. Therefore, we examined the association between distorted body weight perception (BWP) and suicidal ideation. Methods: Data were obtained from the 2007-2012 Korea National Health and Nutritional Evaluation Survey (KNHANES), an annual cross-sectional nationwide survey that included 14 276 men and 19 428 women. Multiple logistic regression analyses were conducted to investigate the associations between nine BWP categories, which combined body image (BI) and body mass index (BMI) categories, and suicidal ideation. Moreover, the fitness of our models was verified using the Akaike information criterion. Results: Consistent with previous studies, suicidal ideation was associated with marital status, household income, education level, and perceived health status in both genders. Only women were significantly more likely to have distorted BWP; there was no relationship among men. In category B1 (low BMI and normal BI), women (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.48 to 3.42) were more likely to express suicidal ideation than women in category B2 (normal BMI and normal BI) were. Women in overweight BWP category C2 (normal BMI and fat BI) also had an increased OR for suicidal ideation (OR, 2.25; 95% CI, 1.48 to 3.42). Those in normal BWP categories were not likely to have suicidal ideation. Among women in the underweight BWP categories, only the OR for those in category A2 (normal BMI and thin BI) was significant (OR, 1.34; 95% CI, 1.13 to 1.59). Conclusions: Distorted BWP should be considered an important factor in the prevention of suicide and for the improvement of mental health among Korean adults, especially Korean women with distorted BWPs.

  • Since growth promotion was defined by Koch(1935), many researches like Benholdt and Thomsen(1942) have conducted studies for understanding problem of puberty growth. Growth promotion means that growth is developed in puberty, and several researchers have reported that the more becomes economic growth, the more becomes growth promotion. Thereupon, this study was attempted to find Maximum Growth Age(M.G.A.), as an index of height growth promotion in Korea, which was obtained by longitudinal observations of the same group. Thus, this study can explain the earlier tendency of growth. To investigate domestic changes in M.G.A., M.G.A. was calculated with the results of cross-sectional researchs using 25 representative papers between 1940-1953 including measurements by Lee(1940) and data by Kim(1953) in this study. Based on the research data published between 1940 and 2000, height and M.G.A. of males and females who were born between 1925 and 1983 were gotten by years, and a trend of growth promotion for height in Koreans was suggested by examining study subjects. Findings of this study are as follows; 1. M.G.A. for height decreased both in males and females; for males, 14.28 years in 1940, 14.24 in 1953, 13.86 in 1967, 12.74 in 1985, and 11.71 in 2000; for females, 12.0 in 1940, 11.52 in 1965, 10.00 in 1978 and 9.77 in 2000. 2. Regression equations and standard errors of estimate concerning M.G.A. for height by years were obtained; for males, Y$_1$(M.G.A.) = 17.21 - 0.059X$_1$, S$_{Y1X1}$(standard error of estimate about the regression line) = ${\pm}$0.62; for females, Y$_2$(M.G.A.) = 13.81-0.042X$_2$, S$_{Y2X2}$(standard error of estimate about the regression line) = ${\pm}$0.64 3. As a result of finding correlation between year and M.G.A. r=-0.763 (p<0.001) for male and r=-0.699(p<0.001) for female were obtained 4. From a view that the growth promotion has been continued before 2000, M.G.A. decreased 0.6 years for male and 0.4 for female per 10 years. 5. M.G.A. for height is as shown in Table 2. 6. It is thought that the future trend of growth promotion for height will follow the progress from 1940s to now. It shall be reviewed again after development of coming several years is investigated.
