A study on severity of cerebro-vascular accident patients in Korea was conduced in order to determine the risk factors affecting the severity of stroke patients. This study was performed by interviewing a total of 477 hospitalized and ambulatory patient of CVA in Seoul, Taejon, and Taegu and Pusan areas from April 1, 1998 through June 30, 1998. The results are as follows; 1. Two hundred and sixty seven $(56\%)$ at Four hundred and seventy seven subjects were manes, md two hundred and ten $(44\%)$ were females. $28.3\%$ of the subjects' ages were 50's and $27.3\%$ were 60's and $18.5\%$ were 70's. $22.6\%$ of the subjects' occupations were home makers, $17.8\%$ were farming. $66.4\%$ of the subjects spent their childhood in urban areas and $33.1\%$in rural areas. $41.7\%$ of the subjects became violin of CVA in Spring, $35.0\%$ in Winter. 2. On physical and mental conditions of the subjects at the occurrence of CVA, $28.7\%$ of the subjects were engaged in physical activities. $22.6\%$ were in a rest stale $19.5\%$ were in sleeping and $18.9\%$ were mentally shocked. $79.4\%$ of the male subjects and $14.8\%$ of female subjects smoked cigarettes. $82\%$ of male subjects drank coffee. $81.1\%$ of the subjects did not exercise regularly. $45.9\%$ of the subjects had the systolic blood pressures in the range of 160 to 199 mmHg and $5.6\%$ of the subjects had hypertension before the occurrence of stroke and $11.7\%$ had diabetes. 3. Of the types of strokes, cerebral hemorrhage was the highest $(49.1\%)$. cerebral infarction was the second $(41.1\%)$. Severe strokes were found in cerebral hemorrhage cases $(52.0\%)$ and cerebral infarction cases $(40.1\%).\;50.9\%$. of the male subjects were moderate cases, $50.9\%$ were severe cases. In females, moderate cases were $72.4\%$, severe cases $15.2\%$. $37.5\%$ of the subjects who had preceding diseases were severe cases, and $15.6\%$ of the subjects without preceding diseases were severe cases. $50.7\%$ of the subjects whose family members had strokes had severe strokes. $34\%$ of the subjects sleeping less than 6 hours a day, $42.4\%$ of the subjects with irregular eating habits, $33.3\%$ of the subjects who liked meat, and $42.3\%$ of the subjects who liked salty foods had severe strokes. $35.9\%$ of the subjects with hot temper, $27.6\%$ of the subjects with moderate temper and $14.5\%$ of subjects with mild temper were severe cases. 4.

This study aimed to determine the effects of the blockage of visual feedback on joint dynamics of the lower extremity. Fifteen healthy male subjects(age: $24.1{\pm}2.3\;yr$, height: $178.7{\pm}5.2\;cm$, weight: $73.6{\pm}6.6\;kg$) participated in this study. Each subject performed single-legged landing from a 45 cm-platform with the eyes open or closed. During the landing performance, three-dimensional kinematics of the lower extremity and ground reaction force(GRF) were recorded using a 8 infrared camera motion analysis system (Vicon MX-F20, Oxford Metric Ltd, Oxford, UK) with a force platform(ORG-6, AMTI, Watertown, MA). The results showed that at 50 ms prior to foot contact and at the time of foot contact, ankle plantar-flexion angle was smaller(p<.05) but the knee joint valgus and the hip flexion angles were greater with the eyes closed as compared to with the eyes open(p<.05). An increase in anterior GRF was observed during single-legged landing with the eyes closed as compared to with the eyes open(p<.05). Time to peak GRF in the medial, vertical and posterior directions occurred significantly earlier when the eyes were closed as compared to when the eyes were open(p<.05). Landing with the eyes closed resulted in a higher peak vertical loading rate(p<.05). In addition, the shock-absorbing power decreased at the ankle joint(p<.05) but increased at the hip joints when landing with the eyes closed(p<.05). When the eyes were closed, landing could be characterized by a less plantarflexed ankle joint and more flexed hip joint, with a faster time to peak GRF. These results imply that subjects are able to adapt the control of landing to different feedback conditions. Therefore, we suggest that training programs be introduced to reduce these injury risk factors.

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.

To ensure the microbiological safety of food items prepared after cooking process, this study was aimed to identify the hazards related with cooked foods donated to foodbanks through quantitative microbial analysis. Five foodbanks located in Incheon and Gyeonggi area among government-dominant foodbanks were surveyed from February to June, 2007. Manager, recipient, donator, type and quantity of donated foot and facility and equipment were examined for the general characteristics of foodbank. The time and temperature of food md environment were measured at steps from after-production to before-distribution, and the microbial analysis was performed mainly with indicator organism and major pathogens. The amount of cooked foods donated to each foodbank was about 20 to 30 servings and consisted of 80% of total donated foods. Only three foodbanks had separate offices for foodbank operation and four institutions had at least one temperature-controlled vehicle. The flow of donated foods was gone through the steps; production, meal service and holding at donator, collection by foodbank, transport (or holding after transport) and distribution to recipients. It took about 3.8 to 6.5 hours at room temperature from after-production to before-distribution. Only aerobic plate counts (APC) and coliforms were found in microbial analysis. The APC after production were relatively high in $8.2{\times}10^5,\;7.4{\times}10^5,\;6.9{\times}10^5$ and $4.2{\times}10^5 CFU/g$ while $2.8{\times}10^6, \;9.4{\times}10^5,\;1.0{\times}10^6$ and $5.4{\times}10^5CFU/g$ before distribution in mixed Pimpinella brachycarpa, mixed chard mixed amaranth and mixed spinach, respectively. The levels of coliforms in mixed chard and mixed spinach were complied with the standards of the Ministry of Education and Human Resources Management The level of APC in boiled pork was increased from $< 1.0{\times}10 CFU/g$ to $4.0{\times}10^2 CFU/g$. One of delivery vessels was shown $6.2{\times}10^3 CFU/100 cm^2$ in APC, which was over the standards for environment. One of serving tables also showed the high level of $1.2{\times}10^3 CFU/100 cm^2$ in APC and $6.6{\times}10^2 CFU/100 cm^2$ in coliforms. These results suggest the sanitary management of holding at donator and the time-temperature control are key factors to ensure the safety of cooked foods donated to foodbank.

상대적으로 홍수량의 규모가 작은 지류 하천에서는 합류부 배수영향으로 제내지 침수 및 제방 범람에 의한 홍수피해의 위험이 가중되고 있다. 특히 지류 합류부에서는 본류와 지류의 홍수유하 조건에 따라 수위가 급격히 증가하므로 인명피해의 가능성 또한 높다. 따라서 본 연구에서는 비구조적 홍수피해저감대책의 일환으로 지류 합류부의 실시간 홍수위 예측기술을 개발하고자 한다. 이를 위하여 지류 합류부 수위의 주요 영향인자를 검토하였고, 잘 구축된 수리학적 모형으로부터 계산된 본류 및 지류의 유량과 합류부 수위자료를 이용하여 홍수위 예측을 위한 경험식을 개발하였다. 개발된 식에 의한 예측결과는 최대 1.0m의 수위오차를 포함하고 있었으나, 평균 0.2~0.3m의 절대오차를 나타내었고, 발생시각은 0~5 hr 앞서 예측 가능한 것으로 나타났다. 본 연구결과로부터 홍수예측 시스템이 구축되지 않은 지류 합류부에서도 쉽게 실시간 홍수예측이 가능하며, 구축된 시스템은 지류의 홍수범람 및 침수피해 예방에 활용될 수 있을 것으로 기대된다.

인류는 서비스경제시대를 맞이하였다. 새로운 경제는 새로운 경영을 필요로 한다. 새로운 경영의 핵심주체는 최고경영자다. 경영자 의사결정의 결과가 기업의 성과로 나타나며, 미래 성장동력의 기반이 된다. 본 연구는 중소 중견기업 경영자의 CEO역량, 기업가지향성, 경영성과가 서로 어떠한 영향을 미치는가를 실증분석 하였다. 연구에선 8개 변수간의 가설이 설정되었다. 또한 그동안 연구되어지지 않았던 기업가지향성과 CEO역량과의 관계도 규명하였다. CEO역량의 측정항목으로 개인효과성, 혁신의지, 기회인식, 정보인식, 관계형성, 사업관리, 리더십, 조직문화, 인적자원관리를, 기업가지향성 측정항목으로 위험감수성, 진취성, 혁신성을 설정하고 본 연구에 부합하게 조작적 정의를 한 후 분석을 진행하였다. 분석 결과 기업가지향성은 경영성과에 유의미한 결과를 도출하지 못했다. 그리고 CEO역량은 경영성과에 정(+)의 영향을 미치는 결과를 나타내었다. 이는 관리적 변인인 CEO역량이 경영성과에 긍정적인 영향을 미친 것으로 판단할 수 있다. 또한 기업가지향성과 CEO역량과의 관계에서도 유의미한 결과가 나타났다. 혁신성, 진취성, 위험감수성이 CEO역량에 긍정적인 결과를 나타낸데 시사점이 있다. 마지막으로, 기업가지향성은 CEO역량을 매개로 경영성과에 통계적으로 유의한 결과를 나타내었다. 연구 당시가 COVID19 바이러스의 세계적 대유행(펜더믹)의 발현시기라는 점에서 본 연구 결과에 주목할 만하다 하겠다. 향후 더욱 변화된 경제환경에서의 CEO관련 요인과 경영성과간의 관계에 대한 심층 연구가 필요하다.

Background: Both objective body shape and perceived body image have been known to influence the mental health. The purpose of this study was to explore the relationship of a combination between actual body mass index (BMI) status and perceived body image with anxiety depressive condition (ADC) in Korean men and women. Methods: This cross-sectional study analyzed data of 26,239 subjects ${\geq}20$ years old from the National Health and Nutrition Examination Survey (2010-2014). This study performed a Rao-Scott chi-square and multivariate logistic regression analyses reflecting survey characteristics and used a variety of independent variables such as socio-demographics and health behavior factors. Results: With all independent variables considered, people with normal weight who perceived themselves as overweight were more likely associated with ADC than a referent group with normal weight who perceived themselves as normal weight, as shown for both men (odds ratio [OR], 1.52; confidence interval [CI], 1.07-2.15) and women (OR, 1.25; CI, 1.06-1.48). Meanwhile, compared to the referent group, men with underweight who perceived themselves as underweight showed a lower association with ADC (OR, 0.63; CI, 0.41-0.97), whereas women with underweight who perceived themselves as underweight showed its higher association (OR, 1.47; CI, 1.10-1.96). Conclusion: A certain group of people categorized as a combination between actual BMI status and perceived body image showed a relatively high likelihood of having ADC, and the gender difference in the likelihood of having the condition for a group was clear. Therefore, this study suggests the need to identify the group at a high risk of ADC on the basis of actual BMI status and perceived body image and to develop an appropriate mental health management program for the group.
