Objective : To identify the effect of lifestyle risk factors on the daily activities and cognition of the older adults in the community using the National Health Insurance Corporation 2015 geriatric cohort database. Methods : Lifestyle risk factors were defined as body mass index (BMI), smoking, drinking, vigorous exercise, moderate exercise, and walking, and basic and instrumental activities of daily living (ADL) and cognitive function variables were included in the analysis. ADL and cognitive function according to sex and age were analyzed using a t-test and one-way ANOVA. The correlation between lifestyle risk factors, ADL, and cognitive function was analyzed using Pearson's correlation analysis, and multiple regression analysis was performed to analyze their influence. Results : The factors affecting basic ADL (BADL) were sex and walking exercises, with an explanatory power of 1.7%. Instrumental ADL (IADL) included age, drinking, and walking exercises, with an explanatory power of 2.6%. Cognitive function included sex, age, BMI, vigorous exercise, and walking, with an explanatory power of 5.3%. Conclusion : Lifestyle risk factors partially affected BADLs/IADLs and cognitive function in community-dwelling older adults. This suggests the need to systematically manage lifestyle risk factors to improve and maintain the healthy lives of older adults facing biological aging.

This paper examines the values of various library functions according to users' points of view. To execute this study, the several 'circumstance', related variables and 'condition' variables that lead to factors or functions of academic libraries were measured. Analysis was carried out in three stages. In the first, factor analysis was used on the three multi variable dimensions to ensure that the groups of variables loaded significantly and uniquely on the respective dimensions. The second phase of analysis involved the use of binary logistic regression analysis to complete research models. In the third phase, t-test was used to identify significant differences in the independent variables for additional explanation of the models. Books, competition & effectiveness and fee verses free (fee-free hereafter) are the three main factors that distinguish not only the purpose of using an academic library but also the degree of influence on knowledge, information and library facilities for the users. In addition, the fee-free factor related to digital library facilities was also uncovered.

Temporary structures provide the accessible working area when building a permanent building structure in the construction operation. Executed in a natural environment, the temporary structure is prone to the external influence factors of underground water, soil conditions, etc. These factors should be carefully considered in designing the temporary structure. The objective of this study is to apply the external influence factors in designing a more reliable earth retaining wall. The research methodology is based on the Taguchi method that has been studied to improve product quality in the industry. An orthogonal array was developed to analyze the interaction between the external influence factors and the internal influence factors. A sample case study demonstrated that the Taguchi method can be used in planning a more reliable temporary structure for earth retaining walls.

This study aims to verify the mechanism of mediated effects for protective factor among the relations of risk factor, protective factor and psychology adaptation under risky situation as functionally deficient family, and to identify the protective factors that protects adolescents with high psychology adaptation level. To achieve these goals, descriptive statistic analysis, regression analysis and logistic-regression analysis were conducted using the 5th year data of the Korea Youth Panel Study (Junior high panel) surveyed in 2008 by National Youth Policy Institute. The study results first shows that the psychology adaptation level of adolescents who experienced functionally deficient family varies depending their self-esteem and attachment to school friends. Second, it was found that there are mediated effects in the impacts of functionally deficient family on psychology adaptation. Therefore, in social work field, it is advisable to focus on the process to mitigate the risk factors or to strengthen protective factors rather than focus on the risk factors of adolescents. With this method, the negative perception of adolescents exposed to risk factors can be changed as well as the way of intervention for supporting them.

예측 기관에 따라서 B2B의 시장 규모 및 성장률에 대한 차이는 있지만 B2B 시장이 빠른 속도로 성장하고 있으며, 이 같은 추세는 계속될 것이라는 점에 대한 이견은 없는 편이다. B2B는 기업에게 비용 절감과 시간 절약, 업무 효율성 증대 등의 다양한 효과를 제공해 줄 수 있기 때문에 앞으로도 그 중요성은 더 커질 것으로 예상된다. 그러나 B2B의 중요성 및 성장세와는 별도로 아직까지 B2B에 참여하는 기업들이 큰 효과를 거두지 못하고 있는 것이 사실이다. 이에 따라 많은 학자들과 컨설팅 회사들이 B2B의 모형, 추진 전략, 성공 요인들을 다양한 각도에서 제시하고 있다. 하지만 B2B에 대한 실증적 연구가 부족하여, 기업의 실무자들이 실질적인 도움을 얻기에는 부족한 점이 있기 때문에 B2B의 성공 요인과 추진 전략에 대한 실증적 연구가 절실히 필요하다. 본 연구의 목적은 B2B 유형 중 가장 널리 활용되고 있는 MRO e-marketplace의 성공에 영향을 주는 요인들을 실증적으로 분석하는 것이다. MRO e-marketplace의 성공 요인을 환경적 특성, 제품 특성, B2B 사이트 특성 등 3 그룹으로 분류한 후, 38개 기업에서 수집된 설문지를 분석하여 MRO e-marketplace의 성공 요인을 실증적으로 분석하였다. MRO e-marketplace의 성공 요인들을 요인 분석한 결과, 기업 내부 환경 요인, 기업 외부 환경 요인, 제품 정보 요인, 제품 공급 능력 요인, 사이트 기본 기능 요인, 사이트 편의성 요인, 사이트 보안성 요인 등 총 8개 요인으로 분류되었다. 한편 MRO e-marketplace의 도입 효과를 측정한 비용 절감, 시간 절약, 업무 효율성 증대, 거래 투명성 증대 등의 4개의 문항은 하나의 요인으로 묶여, 이를 MRO e-marketplace 성공으로 정의하였다. MRO e-marketplace의 성공에 영향을 미치는 요인을 찾기 위해, 추출된 8개 요인과 MRO e-marketplace 성공 간의 상관 관계를 분석하였다. 8개 요인 중에서 기업 내부 환경 요인, 제품 공급 능력 요인, 사이트 기본 기능 요인이 MRO e-marketplace의 성공에 영향을 미치는 것으로 나타났다. 마지막으로 MRO e-marketplace 성공 요인들의 상대적 중요도를 파악하기 위해 회귀 분석을 실시하였는데, 참여 기업의 내부 환경 요인이 가장 큰 중요한 것으로 나타났고, 그 다음은 제품 공급 능력 요인과 사이트 기본 기능 요인으로 나타났다. 이 같은 실증적 결과는 MRO e-marketplace나 B2B의 성공을 위해서는 참여 기업의 내부 환경 조성이 매우 중요함을 시사해 준다. 또한 참여 기업의 제품 공급 능력 요인 역시 MRO e-marketplace의 성공에 직접적인 영향을 주기 때문에 공급기업들의 제품 공급 능력을 높이는데 노력해야 한다. 또한 MRO e-marketplace를 운영하는 기업들은 사이트의 기능을 높이는데 많은 노력을 기울여야 한다는 것을 시사하고 있다. MRO e-marketplace의 성공 요인을 실증적으로 분석한 본 연구의 결과는 MRO e-marketplace와 B2B의 추진 전략의 이론적 모형 개발에 유용하게 활용될 수 있을 것이다. 또한 본 연구의 결과는 MRO e-marketplace와 B2B의 성공을 높이기 위한 추진 전략을 수립하는데 유용하게 활용될 수 있을 것으로 기대된다.
