The purpose of this study was to compare the risk factors of pressure sores and preventive intervention strategies and to provide basic data for the management of pressure sores prevention for long-term care facilities. It was a mixed method study using a systematic literature review and focus group interviews for analysis. A PRISMA flow diagram was prepared in accordance with the research selection process for the systemic literature review. The studies were retrieved from domestic and international studies from 2010 to June, 2019. A total of 8 studies were selected according to the selection criteria. The studies were searched electronically using a search engine with the key words of 'pressure ulcers', 'bedsore', 'decubitus ulcers', 'intervention', 'prevention', 'elderly', and 'long term'. Focus group interviews were conducted through a semi-structured questionnaire for nurses who had worked for more than three years in long-care facilities. The study results suggest that position change and pressure reduction device reduced the incidence of pressure sores and were important for prevention. The use of standardized care protocols is necessary. Multidisciplinary cooperation was an important issue.

Lipid accumulation product (LAP) is a new index reflecting central lipid accumulation and is known to be a strong independent indicator for identifying the risk of cardiovascular disease (CVD) or diabetes mellitus (DM). This study was conducted to assess the relationship between the homeostasis model assessment of insulin resistance (HOMA-IR) and LAP according to the presence or absence of obesity in Korean adults. The study was carried out using data from the 2019 Korean National Health and Nutrition Examination Survey (KNHANES) and included 6,090 adults aged 20 years or older. There were several key findings. First, after adjusting for related variables, the mean of the HOMA-IR levels (M±SE, 95% confidence interval) was positively associated with the quartiles of LAP in the overall population (P<0.001), non-obese (P<0.001) or obese groups (P<0.001). Second, in all the groups (overall population, non-obese and obese groups), the mean value of the fasting blood glucose (all, P<0.001), insulin (all, P<0.001), and the metabolic syndrome score (all, P<0.001) increased with the increasing quartiles of LAP. Insulin resistance was thus positively associated with an increase in the LAP in Korean adults with or without obesity.

The purpose of this study was to analyze the effects of combined exercise on body composition and cardiovascular disease risk factors in sarcopenic obesity elderly women. The subjects for the study were 21 obesity elderly women over 65 years old. They were divided into two groups, the sarcopenic obesity group(n=9) and non-sarcopenic obesity group(n=12). The variables of body composition and CVD risk factors were measured in all the subjects before and after 16-week combined exercise. The findings of this study were as follows; In the sarcopenic obesity elderly women significantly decreased total cholesterol(TC), triglyceride(TG), and left baPWV. The non-sarcopenic obesity elderly women significantly decreased total cholesterol(TC), triglyceride(TG), low density lipoprotein-cholesterol (LDL-C), and left baPWV, but significantly increased high density lipoprotein-cholesterol(HDL-C). The most important finding in this study was that sarcopenic obesity elderly women showed delayed effects of a 16-week combined exercise on HDL, LDL-C, BP, and right baPWV compared to the non-sarcopenic obesity elderly women.

Introduction : A positive thinking has been known to affect the enhancement of performance. One of temperament characters, harm avoidance is thought to be associated with anxiety related behaviors. Golfer showed highest anxiety and lowest score of harm avoidance, compared to any other sports. We hypothesized that positive feedback and reinforcement in golfer would decrease the anxiety and improve the performance. Methods : Fifty one golfers with the age from 15 to 19 were classified into two groups; 25 golfers who used Zinsser's Changing Negative thoughts to Positive thoughts and Beswick's positive self talk when exercise and competition (P-FB) and 26 golfers who had not (controls). Harm avoidance, Spielberg's Trait and State Anxiety, and Golf scores has been assessed at baseline and 6 months later. Results : There was no significant difference in baseline harm avoidance, anxiety, and golf scores between P-FB and controls. The total golf scores in both groups have improved after 6 month later. However, P-FB group showed greater improvement of total scores and putting scores, compared to controls. The state anxiety in PFB group has been decreased, while there was no change in controls. The change in the state anxiety was correlated with harm avoidance and the change in total golf scores. Discussions : The positive thinking has enhanced performance and state anxiety. The improvement of performance and anxiety in golfers was associated with high harm avoidance. The current study showed that the regulation of anxiety with positive thinking was helpful to the performance enhancement in subject with high harm avoidance.

Recently, various alternatives for safety and efficiency of commercial vehicles have been considered, and one of the new alternatives is the application of a digital tachograph. In Korea, the installation of a digital tachograph to commercial vehicles was regulated from 2011 and Korea Transportation Safety Authority developed e-TAS to analyze the monitoring data from digital tachographs installed in the order of 100 commercial vehicles. This study performs the potential impact analysis of the DTG installation, which includes a trend of dangerous driving, a trend of traffic accidents and cost-effective analysis, a trend of fuel consumption and cost-effective analysis, a cost-effective analysis of social benefits using e-TAS data. Depending on the frequency of dangerous driving, the participants are divided into three groups; high-dangerous group, average-dangerous group and low-dangerous group. The high-dangerous driving group shows lower km/liter than the low-dangerous driving group by 15% for buses and taxis and by 30% for trucks. About $CO_2$ emission, the difference becomes bigger; 25%, 25% and 42% for buses, taxis and trucks, respectively. Although this study is a short-term period analysis, the methodology will be applicable for the long-term period analysis with larger data.

Construction has been well known as the industry in which accidents occur more often than other industries. The efforts to eliminate the accidents at construction sites need to be continuously conducted because they tend to cause the social problems such as massive loss of life and property. According to the Korea Occupational Safety and Health Agency (KOSHA), 26,570 (29.3 percent) out of 90,656 workers in total industrial accidents have been occurred in the construction industry in 2016. Particularly, the falling victims are the largest number, which is about 8,699. This number is increasing due to the increase of the large scale, high-rise, and complex construction structures and the various construction methods. In reality, there is a lack of analysis on the risk factors of safety accidents and preventive measures. Therefore, in this study, we have selected risk factors by analyzing the accident cases at construction sites. Based on the results, we conducted a safety practitioner-focused survey and had an interview with safety managers. In analyzing the cases, we have categorized them into three groups such as upper, middle, and lower and compared their statistical results. This study are expected to provide safety management guidelines with workers and safety managers to prevent previously fall accidents at construction site.

This study aimed to analyze convergently the result of the health check-up of the military workers at age of 40, a life transition period in Korea. Data of 4898 military workers who took a health check-up in 2015 was obtained from the national health insurance service and we conducted secondary analysis. As a results, the metabolic syndrome group had a greater current smoking rate, higher number of cigarettes smoked per day, longer period of smoking and higher amount of alcohol consumed. Also, the group scored higher on BMI and had a higher level of total cholesterol, AST, ALT and GGT. In conclusion, as the military workers at age of 40 usually perform important duties, effective programs of reducing smoking and drinking alcohol are needed for their age group, In order to develop health management programs, prior investigation to take into consideration specific age and military rank is necessary.

본 논문은 금융실명제가 기업에서 발표하는 회계학적 이익정보에 대한 주식가격의 변화에 미치는 영향을 분석하였다. 이는 금융실명제실시 이후에는 기업에서 창출해 내는 기업이익이 진정한 이익에 보다 더 접근을 할 것이라 예상과 채무분석가의 기업이익에 대한 예측치는 진정한 이익에 대한 예측치이므로 금융실명제 실시 이후에는 예측오차가 감소할 것이다는 일반적 예상을 검증하기 위한 것이다. 본 논문은 먼저 1992년과 1993년 12월 결산기업에 대하여 비기대이익을 계산하여 두 해에서의 차이를 분석하였고, 계산된 비기대이익과 기업이익 공시시점에서의 비정상수익율과의 관계를 회귀분석을 통하여 분석하였다. 채무분석가의 예측치로서 대우경제연구소에서 1992년과 1993년 12월에 각각 발표한 각 상장기업의 이익에 대한1992년 및 1993년의 예상치를 각각 년도의 예상기업 이익으로 사용하고 실제로 1993년과 1994년 초에 공시되는 기업이익과의 차이를 조사하였다. 비정상수익율의 계산은 시장위험조정모형과 시장조정모형을 사용하였고 일별수익율에 의하여 측정하였다. 사건 시점은 주주총회 일을 중심으로하여 여러 사건 기간을 택하여 분석을 하였다. 실증적 분석 결과를 보면, 전체표본을 대상으로한 재무분석가의 추정치에 의하여 계산된 비기대이익의 분산이 금융실명제 실시 이후가 실시 이전에 비하여 더 크게 나타났다. 이러한 결과는 금융실명제의 실시로 인하여 재무분석가의 예측이 오히려 더 부정확하게 나타난 것이라 할 수 있다. 이러한 결과는 실명제 실시에 따라서 기업이익예측에 대한 불확실성이 더 증가를 하여 기업이익 공시시점에서의 비기대이익의 측정에서의 오차가 오히려 증가하였다는 것을 알 수 있다. 그러나 전체표본을 소그룹으로 나누어서, 1부에 속한 기업들과 대형 주기업들을 대상으로한 분석에서는 이 두 소그룹에 속한 기업들이 각각 금융실명제실시 이후가 금융실명제 실시 이전보다 비기대이익의 분산이 작게 나타났다. 이러한 결과는 1부에 속한 기업들과 대형주기업들에서 는 금융실명제실시로 채무분석가들의 이익 예측치가 더 정확성을 지니게 된 것으로 해석된다. 이익반응계수의 추정에서 예상했던 바와는 반대로 금융실명제 실시 이후에 계수의 크기가 오히려 감소하였다. 소그룹으로 나누어서 분석한 결과도 마찬가지였다. 금융실명제 실시가 기업회계이익에 미친 영향은 비기대이익의 측정을 통하여 일부 가설과 일치하는 결과를 얻었고, 이익반응계수의 측정에서는 가설과 일치하는 결과를 얻지 못하였다.
