This study explored the factors affecting the acceptance of public recording in SNS post. Using SPSS 21.0 program and AMOS 21.0 program, major results were derived through exploratory factor analysis, confirmatory factor analysis, correlation analysis, and path analysis. The results are as follows: First, the risk of personal information leakage on SNS posting has a significant negative impact on the attitude toward SNS posting. Second, the security of the SNS posting has a significant effect on the attitude toward the SNS posting. Third, the concern about privacy of SNS posting has a significant negative impact on the attitude toward SNS posting. Fourth, the attitude toward SNS posting has a significant effect on the intention to accept the SNS posting. The above results suggest that the SNS post recording should be able to collect opinions of SNS users from a long-term viewpoint.

최근 산업안전/보건분야에서 누적외상성질환(Cumulative Trauma Disorders： CTDs)과 직업성요통(Low Back Injury)과 같은 근골격계질환은 산업현장에서 어렵지 않게 발견할 수 있는 신종 산업재해의 일종이다. 특히 미국의 경우, 발생건수와 그로 인한 인적/물적 손실이 급격하게 증가되고 있는 것으로 나타나고 있다. 그러나 미국과 같이 근골격계질환의 폐해를 일찌감치 인식하고 그 해결방안을 연구해온 나라들에서는 현재 환자관리 및 인간공학적인 기준 등을 포함하는 예방지침들이 잘 정착되어 있는 실정이다. 우리나라의 경우에는 작업환경 등의 조건과 상황이 미국과 같은 구미 선전국과 비숫하고, 특히 제조업의 생산체계가 그런 나라들과 매우 유사하여 근골격계질환의 발생과 그로 인한 인적/물적 손실이 적지 않을 것이라고 예상할 수 있지만 아직까지 CTDs에 대한 전반적인 이해가 부족하고, 정확한 실태가 파악되지 못하였으며, 따라서 체계적인 관리 대책 또한 마련되어있지 않은 실정이다. 본 조사에서는 서울 근교의 수송기계관련 사업장의 작업들에 대한 작업자세에 중심을 둔 인간공학평가를 통하여 조사 작업의 근골격계질환에 대한 상대적인 위험도, 위험요인 등을 파악하고, 그에 따른 개선 대책의 방향을 제시하고자 하였다. 특히, 각 부위별 위험점수와 부위별 증상호소율의 상환분석결과, 작업자 개인적 수준에서는 통계적으로 유의한 차는 없는 것으로 분석되었으나, 부서별로 분석한 결과, 작업시 주로 사용하는 오른쪽 상지의 경우, 오른쪽 어깨, 팔꿈치, 손목 순으로 통계적으로 유의하게 관련이 있는 것으로 나타났다. 즉 증상호소율과 해당 신체부위의 위험도 점수는 서로 정적(positive)한 관계에 있는 것으로 나타났고, 상지 중 주로 사용하는 오른쪽 부담의 위험도 자세 점수와 증상호소는 비교적 높은 상관관계에 있는 것으로 나타났다. 따라서 이와 같은 인간공학적 분석결과는 향후 인간공학적인 개선대책의 개발 뿐만 아니라 의학쪽에서 근골격계질환을 접근하는 초기단계에서 매우 유용한 역할을 할 수 있으리라 생각된다.

This study examined the factors associated with recurrent falls among the community-dwelling elderly. The participants were 329 community-dwelling elderly. The data was collected from February 5, 2010 to February 14, 2010. Over the past 1 year, 14.3% of the 329 participants fall once, and 4.0% experienced recurrent falls. There was a significant difference among the non fallers, single faller and recurrent fallers with regard to the static balance(F=5.86, p=.003), dynamic balance(F=24.32, p<.001), risk of fall(F=9.94, p<.001) and compliance of prevention behavior related to falls(F=3.09, p=.047). The analysis results for the correlation between variables showed that the number of falls had a negative effect on the knee flexors muscular strength(r=-.15, p=.008), static balance(r=-.16, p=.004) and compliance of prevention behavior related to falls(r=-.12, p=.030) and a positive affect for the dynamic balance(r=.26, p<.001), depression(r=.13, p=.019) and risk of falls(r=.30, p<.001). The variables explained 36.0% of the variants in the occurrence of recurrent falls. Therefore, an effective recurrent fall prevention program should focus on multiple risk factor intervention.

본 논문에서는 공사현장 작업자의 실질적 영향을 미치는 요소들을 고려하여 인공지능기반의 실시간 위험성 추정 기법을 개발하였다. 기존 재난안전학 또는 안전공학에서는 위험성평가를 실시하여 강도·빈도에 의하여 위험성을 추정하고 도출된 값을 통해 위험한 정도를 분류하는 경우가 많다. 그러나 대부분의 공사현장에서는 정적인 위험성평가를 통해 해당 유해위험요인을 근거로 형식적인 위험성평가가 이루어지고 있기 때문에 대부분의 사고 후 증빙 자료로만 활용되고 있는 것이 현실이다. 이 위험성평가를 진행하면서 변화하는 환경의 유해위험을 실시간으로 반영할 수 없게 되고, 이는 실질적인 작업자의 안전을 보장해 주지 못하는 문제를 발생시킨다. 이러한 점에서 위험성평가와 더불어 실질적인 안전한 작업장을 만들기 위해서 작업자의 건강정보 및 실시간 공사현장의 영상정보에 기반한 위험성 추정 기법은 실질적 안전사고를 예방하는 방법론 중 하나가 될 수 있다. 작업자의 건강정보는 개개인 맞춤형 건강 데이터에 근거한 해석이 가능하고 실시간 공사현장 영상은 작업 중 발생할 수 있는 돌발상황에 대비하기위해 사용된다. 이러한 위험성 추정 방법은 다양한 공사현장의 위험성 추정 기법으로 사용될 수 있다. 이로 인해 높은 정확도의 위험성 추정 수치를 얻을 수 있으며, 이는 실질적안 안전 예방활동에 있어서 매우 중요하게 작용한다. 위험성 추정 수치 예제를 통하여 본 논문에서 제시된 위험성 추정 방법론이 타당함을 확인하였다. 본 논문에는 기존 위험성평가에 더해 작업자의 건강정보 및 공사현장 실시간 영상정보를 이용하여 실질적인 작업자 안전을 위한 예방 방법을 제시하였다.

This study is a descriptive research study conducted to understand the effects of hospital nurses' COVID-19 risk perception, media dependence, government trust, resilience, and Socio-psychological stress on COVID-19 prevention behavior. Data were collected from 200 nurses at university hospitals, and the collected data were analyzed using descriptive statistics, t-test, Pearson's correlation analysis, ANOVA, and multiple regression analysis using the SPSS 24.0 program. The average age of the subjects was 29.8 years old, the hospital experience was 6.6 years, and the prevention of COVID-19 was high with 4.3 points. COVID-19 prevention behavior showed positive correlation with COVID-19 risk perception, resilience, and media dependence and negative correlation with socio-psychological stress. Factors influencing COVID-19 prevention behavior were COVID-19 risk perception, resilience, socio-psychological stress, and media dependence. To ensure that hospital nurses' COVID-19 prevention behaviors can be continued, it is necessary to appropriately manage COVID-19 risk perception and media dependence, and to develop and apply an intervention program to strengthen resilience and reduce socio-psychological stress.

This study intends to analyze the trend of employment rate of men aged 55~64 in 15 OECD countries from 1980 to 2005. Furthermore, this study means to examine the determinants of men aged 55~64 in 15 OECD countries to support the labor force participation among them. The analysis is based on the data of OECD, ILO and LIS. The analysis method is Arellano and Bond(1981)'s difference GMM which used instrumental variables by dynamic panel model which estimates state dependency of labor market participation and individual panel's heterogeneity. The main results from this analysis are summarized in three points. First, the employment rates of men aged 55~64 had decreased until the middle of the 1990s, while that has been increasing since 1995. Second, the sate dependency strongly worked in the employment rates of 55~64 men and positive period effect was observed for 1980~2005. This study cannot find the pull effect of public pension, while labor market push effect have negatively affected. Third, temporary work rates had contributed to increase the employment rate of men aged 55~64 for 1996~2005. The poverty has become the mechanism of the labor.

The purpose of this study was to find the effects of long-term combined exercise on regional bone mineral density(BMD) and cardiovascular disease(CVD) risk factors in the elderly with osteoporosis(OP). For the purpose, the subjects of this study were separated by two groups with thirty-one elderly women, who the first group was combined exercise group(CEG, n=16) and second group was non exercise group(CON, n=15). The combined exercise program was made up of warm-up (10min), work-out (aerobic; 30~45min/HRR 40~60%, resistance; 1RM * 50-70%, 8-10 * 2set ~ 10-15 * 1set), and cool-down (10min). Exercise group of the inspection have been trained 5 times a week for 1years. The results : At first, the variables of regional BMD were significantly different to pelvis, spine, trunk and T-score in two groups. At second, the variables of CVD risk factors were significantly different to SBP and DBP as well as TC, TG, LDL-C and HDL-C in two groups. As results of these conclusion, this study have positively effect shown that CEG was superior to CON in regional BMD(pelvis, spine, trunk and T-score), blood pressure(SBP, DBP) and plasma lipids(TC, TG, and LDL-C). Especially, the long-term combined exercise was provides a striking overall health quality of life with improving BMD and reduced CVD risk factors in the elderly with OP. In the future, other researches should deal with specific measures that reduction in mortality due to chronic disease and improvement quality of life for the development of programs in multiple researches of osteoporosis and chronic diseases.
