Stress or march fractures among military personnel, especially recruits, has been appreciated for many years. According to the classical references, the second metatarsal was one of the first sites identified as a focus for march fractures and radiological evidence of fracture appeared as late as several weeks. The purpose of this study was to document the clinical feature of march fractures in Korean infantry soldiers. From 1997 to 1998, at one infantry medical company of OO infantry corps in Korea, 15 (19cases) patients with march fracture were detected among infantry soldiers. There were some different finding in the fracture site and its clinical features from the previous foreign reports. 1. There were pain and local swelling in all cases as clinical manifestation. By physical examination, direct point tenderness on the location of the fractured metatarsal shaft was characteristic. 2. On roentgenographic examination, cortical fissuring or break was seen one week after onset of symptoms and external callus was seen from two weeks or at the least four weeks. Oblique view was more useful than AP view in the diagnosis of march fractures. 3. The third metatarsal was the most frequently involved site(7 cases, 48%). and the second metatarsal was Jess frequent(3 cases, 20%). This difference of frequent site with previous reports might be attributed to the relatively long shaft of the third metatarsal, but should be analyzed in further study. 4. The incidence of the development of march fracture was 1 per 104 infantry soldiers.

The result of this paper runs as follows: 1. The theory of preclinic phase (=mibyung) was scientifically completed as one basic philosophy in "NAEKYUNG(內經)" and on influenced in the coming generations. Two principles for mibyung is to grow good energy and to avoid etiological cause. 2. So far oriental medicine has responded to already diseases, while to recognize the importance of mibyung is to convert it into preventive medicine which study and improve health. In spite of the opinion that no disease is health and no health is disease, the contrite of medical approch by the relative importance is necessary by understanding the steps of mibyung between health and disease with subdividing the steps of the occurance therefore, the scope of oriental medicine may be recognized from every disease to mibyung, that is, health. 3. Diagnosing and treating in the step of mibyung has more important meaning than suffering step because the checkup of mibyung means early examination and treatment. Mibyung can make an opportunity that improve scientific contradiction and defect of oriental medicine. However, scince the theory and practice lack the arrangement and study, much exertion and discussion is necessary.4. The diagnosis and cure in mibyung doesn't have many methods for treating, its index and standard isn't nified, and related theory is of small quantity. But the most prominent means of solution. with combination with other sciences and through the convertion into modem clinical examination, is to accomplish moderization, objectivity and indexation, etc. 5. The representive mibyungs are a hereditary disease, immune lack, mutation, early tumor, incubation of hepatitis and each infectious diseases, stress, etc. Since every science is the product of the times, it has the historical limits. As the times develop, the desire for good health is growing. Therefore we should consider above request in this times.

Recently, polishing tile(porcelain homogeneous polished tile) was used in the construction field as a finishing material. But, there happened some problems such as tile exfoliation by construction condition in early ages. Also, for use of polishing tile in the dry wall system which used to lightweight wall, the examination of adhesive stability of polishing tile is needed. In this study, adhesive strength of Polishing tile was investigated by tile bond types on gypsum board and non asbestos board coated by tar-urethane and Polymer modified cementitious waterproofing membrane(Series I). Then, the effect of heat stress and vibration was estimated on gypsum and non asbestos board(Series II). As the result of study are the follows; (1) Polishing tile(600$\times$400mm) construction on waterproofing layer : Both laboratory estimation and spot examination sieve were happened that fall of tile because their hardening speed is late. (2) To using powder style adhesives in the dry wail with waterproofing layer : Adhesive strength of tile is Influenced by interface bond area and base side condition. (3) Shock and heat stresses : obvious decline of adhesive strength is not happened

The purpose of this study was to estimate the prevalence of hypertension, and to assess the risk factors associated with hypertension in elderly (over 65 years old) Koreans, using data from the 4th Korean National Health & Nutrition Examination Survey (the 4th KNHANES), 2007~2009. A total of 1,887 participants were analyzed for assessing the risk factors after excluding those who took hypertension medicines or underwent diet therapy (hypertension perceivers). On the other hand, in analyzing prevalence, a total of 3,526 people were analyzed, including hypertension perceivers. Hypertension was more frequently found in female (64.1%) and urban (62.0%) groups compared to male (55.6%) and rural (57.4%) groups. The mean age of the hypertensive group was significantly higher than that of normal group. The mean values of total cholesterol levels were also significantly higher in the hypertensive group, while body weight, waist circumference, fasting blood glucose, hemoglobin, hematocrit, LDL-cholesterol, and HDL-cholesterol were not. Multiple logistic regression showed that smoking was significantly related to the prevalence of hypertension, but alcohol drinking, stress, obesity, hypercholesterolemia, hypertriglyceridemia, diabetes, anemia, and nutrient intakes were not. The results of this study does not support clear relations of hypertension with chronic diseases including obesity, hyperlipidemia, anemia, and diabetes as well as nutrient intakes among a Korean elderly population. A prospective long-term research study is needed to establish the effects of these factors on hypertension.

This study identifies the factors influencing Quality of Life (QoL) in both male and female workers with diabetes mellitus and examines the differences between them. Using data from the Korea National Health and Nutrition Examination Survey (KNHANES) for 2010-2017, 1693 workers (1082 males; 611 females), aged 19 or over, with diabetes mellitus were enrolled in the study. Data were analyzed by complex sample linear regression using SPSS/WIN 23.0. The factors influencing QoL differed between males and females. The common factors included household income, education, job, stress, disease duration, and disease complications. The additional factors in males included working style, and, in females included age, marital status, drinking habits, and the treatment and control of the disease. Males had a higher QoL than females in all the sub-factors. Patients with diabetes mellitus require gender-specific intervention and governmental and social policies that can support it must be developed.

Depression is a major health problem that can lead to mortality. This study was conducted to assess the risk factors associated with depression in a group aged over 65 years by analyzing nationally representative Korean survey data. A total of 1,209 subjects were analyzed among the participants of the 2014 Korean National Health and Nutrition Examination Survey. Statistical methods for a complex sample were applied by using SPSS program(windows ver. 24.0). Depression assessments were carried out by using the 9-item depression module of the Patient Health Questionnaire-9 (PHQ-9). Depression ($PHQ-9{\geq}5$) was more frequently found in females (33.2%) compared to males (16.1%). However, there was no evidence suggesting that characteristics such as residence area, income level and age, except for educational level, were related with depression. The results of the logistic regression analysis showed that i) health habits such as smoking (OR: 2.26) and lack of aerobic physical activity (OR: 1.62), ii) mental health status such as bad self-rating of health status (OR: 4.30), more stress (OR: 8.31), and bad health-related quality of life (by EQ_5D, OR: 3.41), iii) chronic diseases such as obesity (OR: 0.66), hypercholesterolemia (OR: 1.57), anemia (OR: 1.91), and iv) low intake of energy (OR: 1.84) and calcium (OR: 1.71) were significantly associated with depression. This study suggests that certain characteristics of health habits, mental health status, chronic diseases and nutrient intake may be associated with depression. Prospective research on long-term control is needed to establish causal connections among those factors with depression.

This study was conducted to compare the nutrient intake, physical characteristics, and health status according to daily fruits and vegetables intake of adolescents using the Korean national health and nutrition examination survey for the sixth period (2013~2015). Subjects were 1,096 adolescents aged 13~18 years. The average daily intake of fruits and vegetables was $518.49{\pm}4.94g$. The two groups (insufficient, sufficient) were divided by fruits and vegetables intake (<500 g/day, ${\geq}500g/day$) and the ratio of the insufficient group was 75.9% while that of the adequate group was 24.1%. The mean of intake of energy, calcium, phosphorus, sodium, potassium, iron, thiamin, niacin, vitamin C and dietary fiber differed significantly between the insufficient and sufficient groups (P<0.01, P<0.001). However, there was no significant difference in physical characteristics between groups. The self-perceived health status was better in the sufficient group (P<0.05), while the insufficient group was aware of more stress in their daily life (P<0.05). The serum triglyceride was significantly higher in the sufficient group (P<0.05), while the total cholesterol was lower (P<0.05). As the characteristics of fruits and vegetables are different, it will be necessary to determine standards for consumption of each type. It is also necessary to consider whether a fruits and vegetables intake of 500 g would be a reasonable standard for adolescents. Nevertheless, the results of this study indicate efforts to increase fruits and vegetables intake by young people are necessary.

The purpose of this study was to examine the relationships between the nutrient intake and level of depressive symptoms. A total of 5,761 subjects with depression were selected for the main data analysis from a Korean National Health and Nutrition Examination Survey, KNHANES (2016), and were divided into low depressed and high depressed groups. The data were analyzed by descriptive analysis, ${\chi}^2-test$, logistic regression, and t-test using SPSS 24.0 statistics. The results revealed significant differences in the prevalence of depression according to sex (P<0.001), age (P<0.001), income (P<0.001), and education (P<0.001). Regarding the health behavior, higher stress levels (P<0.001) and smoking habit (P<0.001) appeared to be strongly associated with high levels of depression. On the other hand, the possibility of experiencing depressive symptoms was lower when the number of walking days per week was more than 3 days (P<0.05), when the number of working days per week was more than 5 days (P<0.01), and the rate of aerobic physical activity was higher. Based on the 'Dietary Reference Intakes for Koreans 2015', the subjects in the low depression group showed better intake of energy and 22 nutrients than the high depression group.

There is only limited evidence for the association between fruit and vegetable consumption and mental health in Korea. This study examined the relationship between fruit and vegetable consumption and mental health according to physical activity among Korean adult women. Based on data of the Korean National Health and Nutrition Examination Survey (2014-2016), a total of 5,332 participants were included in this analysis. With increasing fruits and vegetables consumption, the prevalence of depressive mood was significantly decreased (p for trend=0.0248). The prevalence of stress perception (p for trend=0.0422) and the prevalence of depressive mood (p for trend=0.0300) were decreased with increasing fruit consumption. The prevalence of depressive mood was significantly decreased when fruit and vegetable consumption (p for trend=0.0370) and fruit consumption (p for trend=0.0356) were increased for those Korean women with low intensity of physical activity. For the obesity group (Body mass index 25 kg/㎡), the prevalence of depressive mood was decreased with increasing fruit and vegetable consumption (p for trend=0.0111) and increasing fruit consumption (p for trend=0.0165). In conclusion, fruit and vegetable consumption were associated with mental health according to physical activity among Korean adult women. Further prospective studies are warranted to explore the association between fruit and vegetable consumption and mental health among Korean adult women.
