The purpose of this study is to analyze the winning factors in male singles tennis games in Korea. The database includes 30 university and semi-professional players. This study uses Windows SPSS(Version 10.0) statistical package, which investigates service, stroke, volley, and return functions of the players in terms of scoring, success-failure rate, and scoring patterns. The findings are as follows. First, except for the service, the players mainly used strokes and balanced use of fore- and back-hand strokes contributed to winning. Second, the more often the players used net plays, the better chance of winning they got. Third, service was a crucial factor in winning and the narrower the gap of intensity between first service and second service, the better chance of winning the players got. And finally, success of first service greatly improved the chance of scoring for the server, and returning the served ball toward the opposite direction of the server's movement proved effective for the receiver. Further sports-psychological investigation is called for to better understand the winning factors and the nature of the tennis game.

This study aimed to identify worker groups that are to accidents and to track the changes in their socioeconomic status there after. We analyzed the Korean Labor and Income Panel Study (KLIPS) database(2001–2006) were recorded according to the participant’s economic activity status at the beginning of follow-up, and economic activity status was. During the follow-up period, the unemployed group experienced more accidents that resulted in disability than the economically active group. Interestingly, the unemployed group also had the highest industrial accident rate. Among the employed, daily and unpaid family workers were more vulnerable to disabilities. After the accidents, the participants tended to become economically inactive or unemployed. Compared to other worker groups, the economically inactive, unemployed, and daily and unpaid family workers experienced higher rates of accidents and faced graver conditions as a result. Although they constitute a significantly large part of society, these vulnerable workers are not currently covered by any social security measures, such as accident surveillance, training, and accident insurance. Social policy should therefore be directed toward protecting these vulnerable worker groups.

서울지역의 호흡기질환으로 입원한 환자를 대상으로 미세먼지 노출에 대한 건강영향을 평가하였다. 건강보험공단의 2002-2010년 동안 표본코호트의 만성폐쇄성 폐 질환(COPD), 천식 및 폐렴과 같은 호흡기 질환으로 입원한 13,974명의 환자를 대상자로 하였다. 추적관찰 기간동안 미세먼지 농도가 50ug/m3 이상에서 10ug/m3 증가할 때 15세 미만의 연령층에서는 1.38%, 65세 이상의 연령층에서는 1.62%, 75세 이상 연령층에서는 2.87% 호흡기질환으로 입원이 증가하였고, 폐렴환자는 1.50%, COPD 환자는 1.51%, 폐렴 및 천식환자는 1.55% 입원이 증가하였다. 또한 미세먼지가 80ug/m3 이상에서는 65세 이상 연령층에서 3.71%, 75세 이상 연령층에서 4.25% 입원환자가 증가하였다. 높은 미세먼지농도와 호흡기 질환으로 입원한 환자들과, 특히 노인에서 관련성이 높게 나타났다. 이미 호흡기 질환이 있었던 사람들, 특히 나이가 많은 환자는 고농도의 미세먼지에 노출되지 않도록 주의해야 한다. This cohort study aimed to identify the effects of daily PM10 exposure on the hospital admission of patients with respiratory diseases, during the nine-year period (2002-2010), in Seoul, Korea. The research subjects were 13,974 patients who had been hospitalized with respiratory diseases, including chronic obstructive pulmonary disease (COPD), asthma, and pneumonia. During the follow-up period, an increase of 10 ug/m3 in PM10 under the threshold of 50 ug/m3 of PM10 led to hospital admission in 1.38% of the age group younger than 15 years, 1.62% in those 65 years or older, 2.87% in patients 75 years or older and in 1.50% of pneumonia patients, 1.51% of COPD patients, and 1.55% of pneumonia and asthma patients. Under the threshold of 80 ug/m3 of PM10, there was a 3.71% increase in new patients admitted in the age group 65 years or older and 4.25% in those at least 75 years old. Our study found that high PM10 was associated with increased risk of admission of respiratory patients, especially in the elderly. People who already have a respiratory disease should refrain from exposure to particulate matter when there is a high concentration of PM10, especially older patients.
한국인 60세 이상 노년층의 황반변성과 백내장의 위험요인 - 국민건강보험공단 노인코호트 자료를 활용하여 -
박해용,이은희,박윤숙 한국융합학회 2017 한국융합학회논문지 Vol.8 No.10
연구목적: 60세 이상 인구에서 나이 관련 안질환인 백내장과 황반변성의 위험요인을 알아보고자 한다. 연구방법: 건강보험공단 노인코호트(2002년-2013년)자료를 활용하여. 연구기간동안 노년층의 대표 안질환인 백내 장(ICD-10; H25)과 나이관련 황반변성(ICD-10; H353)을 진단받은 341,588명을 대상(남: 44.18%, 여:61.887%)으 로 두 질환의 유병률 결정 요인을 Cox 확률비례위험모형을 이용하여 분석하였다. 분석결과: 백내장과 나이관련 황반변성 유병율은 여성이, 나이가 많을수록, 고소득 집단일수록, 고혈압, 심장질환, 당뇨가 있으면 더 높게 나타났다(p<0.0001). 결론: 60세 이상 노인들은 고혈압, 심장질환 및 당뇨와 같은 만성질환이 많을수록 백내장과 황반변성 유병률이 더 높았다. 눈이 건강한 고령화 사회를 만들기 위해서는 노인들의 만성질환 관리가 필수적으로 요구된다. Purpose: This study was conducted to identify factors associated with cataract and age-related macular degeneration in elders. Methods: In total, 341,588 men(44.18%,) and women(61.887%), aged over 60, were recruited from Korean National Health Insurance Service-Senior(2002-2013). We also analysed the factors which determine the prevalence of contract (ICD-10: H25) and age-related macular degeneration(ICD-10: H353) using Cox proportional hazard regression model Results: The subjects who were women, in older age, the group of higher income level, with hypertension, with heart disease, and with diabetes, the prevalence of both contract and age-related macular were increased(p<0.0001). Conclusion: The prevalence of contract and age-related macular degeneration were higher in old age of Korean who has chronic diseases such as hypertension, heart disease, and diabetes. The management of chronic diseases are essentially required in elderly for more healthy eye in aged society.
