The present study aims to examine the relationship between self-reported sensory impairment and cognitive function among older adults in Korea. Drawn from the 2017 Survey of Living Conditions and Welfare Needs Korean Older Persons, a total of 10,082 adults aged 65 and over were included in analyses. Results from hierarchial multiple regression analysis show that those who reported greater subjective discomfort about vision, hearing, and oral function were more likely to have poor cognitive function. Results from hierarchial logistic regression analysis show. Results from logistic regression analysis show that having hearing and oral discomfort increased the a risk for dementia. Findings suggest that it is necessary to manage sensory function of the elderly at the government level and to develop self-evaluation tools to monitor changes in sensory function for older adults. Future research should target finding effective ways to improve health of older adults.

XQuery is a new recommendation for XML query. As an efforts for extending XQuery capabilities XML insertion and deletion are being studied and its standardization are going on. Initially XML databases are developed simply for XML document management. Now their functions are extending to OLTP. In this paper we are adding updating functions to XQuery processing system that is developed only for XQuery retrievals. We suggest the structure of tables, numbering schemes for hierarchical structures, and the methods for SQL translations for XQuery updates.

첨가제는 기유인 탄소와 수소로 된 유기화합물과 함께 존재하면서 윤활기능을 높여 주는 것으로써 유황, 염소와 인을 주요성분으로 하고 있다. 비록 이들 첨가제의 화학적 구조와 반응에 따라 윤활기능 및 역할을 체계적으로 연구하는 것은 매우 복잡하고 때로는 불가능 하지만 가능한 범위에서 화학적 관계와 윤활작용의 상호관계를 살펴보기로 한다.

This study examined the effects of geriatric depression and geriatric stress on cognitive impairment. In particular, the dementia groups were divided into Alzheimer's disease and vascular dementia. A normal group was used as the control group. For each group, the geriatric depression using the geriatric depression scale (GDS) and geriatric stress using the geriatric stress scale (GSS) was compared with the regression and correlation results of cognitive impairment. Statistical tests, such as descriptive statistics, Kruskall-Wallis, correlation analysis, and multiple regression analysis, were performed. For the Alzheimer's group, the GDS and GSS correlated with the cognitive impairment, but only the GDS showed a cause-and-effect relationship with cognitive impairment. In particular, the male group with Alzheimer's disease showed clear confirmation. In addition, geriatric stress was found to be associated with geriatric depression. In conclusion, geriatric depression affects the cognitive impairment directly and geriatric stress affects the cognitive ability indirectly through geriatric depression. In this study, the Alzheimer's disease, vascular dementia, and control groups had a small sample size. Therefore, the external validity in future studies can be increased using a larger sample size for each group.

This paper planned to review positively the influence of leading variables - Functional benefits, Emotional benefits, Self-expressive benefits over Consumer-brand relationship, and the structural relationship between Consumer-brand relationship and Brand attachment, Word-of-mouse. For it, we verified our hypothesis utilizing Hierarchial chi-square analysis that was available to statistically verify the size between 2 paths out of Structural models As the result of research, Emotional benefits was more influential than Functional benefits in the formation of Consumer-brand relationship. Additionally, the influential difference between Emotional benefits and Self-expressive benefits was not found in the formation of Consumer-brand relationship. In other words, both Emotional benefits and Functional benefits were proved to have a positive influence on forming Consumer-brand relationship. On the other hand, Self expressive benefits played a more influential role than Functional benefit in the formation of Consumer-brand relationship. The fact was also proved that the higher the formation level of Consumer -brand relationship was, the greater positive influence over Brand attachment and Word-of-mouse Through the above results, it is more desirable to establish brand strategy for forming Consumer-brand relationship through Emotional benefits and Self expressive benefits rather than Functional benefits. Additionally, the Consumer-brand relationship formed by Value benefit is expected not only to get the level of attachment, showing like love, toward the brand deeper, but also to achieve the effect of positive, long term communication through voluntary Word-of-mouse.

The purpose of this study was to examine whether self-differentiation mediates the relationship between adolescents' family functioning and self-esteem and to examine whether peer support and family conflicts had moderated mediating effects. For this purpose, 522 students from four high schools in Gyeonggi province were surveyed about their family functioning, self-differentiation, self-esteem, and peer support. The results were analyzed using SPSS 21.0 and PROCESS. The mediating, modulating, and moderated mediating effects were analyzed. The results of this study were as follows. First, correlation analysis showed that family functioning, self-differentiation, self-esteem, and peer support were significantly positively correlated. Second, the moderated mediating effects of peer support were as follows. First, self-differentiation had a partial mediating effect in the relationship between family functioning and self-esteem such that family functioning and self-differentiation were positively correlated and self-differentiation and self-esteem were positively correlated. Second, peer support had a moderating effect in the relationship between family functioning and self-differentiation that promoted self-differentiation. Thus, peer support affected family functioning and self-differentiation. Third, verifying the moderated mediating model of peer support by combining the mediation model of self-differentiation and the moderation model of peer support identified above showed that self-differentiation mediated the relationship between family functioning and self-esteem. Thus, family support affected self-differentiation and self-differentiation affected self-esteem. The significance of this study was as follows. First, it showed that self-differentiation significantly mediated the relationship between family functioning and self-esteem, clarifying the relationship between family functioning and self-esteem. Second, it showed that peer support moderated the relationship between family functioning and self-differentiation, identifying a mechanism that promotes self-differentiation. Third, it showed the mediation of self-differentiation of the relationship between family functioning and self-esteem depended on peer support.

동사와 기본구 사이의 문법관계 분석은 품사부착과 기본구 인식이 수행된 상태에서, 동사와 의존관계를 갖는 기본구를 찾고 각 구의 구문적, 의미적 역할을 나타내는 기능태그를 인식하는 작업이다. 본 논문에서는 바이오 문서에서 단백질과 단백질, 유전자와 유전자 사이의 상호작용관계를 자동으로 추출하기 위해서 제안한 문법관계 분석 방법을 적용하고 따라서 동사와 명사고, 전치사고, 종속 접속사의 관계만을 분석하며 기능태그도 정보추출에 유용한 주어, 목적어를 나타내는 태그들로 제한하였다. 기능태그 부착과 의존관계 분석을 통합해 수행하였으며, 지도학습 방법 중 분류문제에서 좋은 성능을 보이는 지지 벡터 기계를 분류기로 사용하였고, 메모리 기반 학습을 사용하여 자질을 추출하였으며, 자료부족문제를 완화하기 위해서 저빈도 단어는 품사 타입 또는 워드넷의 최상위 클래스의 개념을 이용해서 대체하였다. 시험 결과지지 벡터 기계를 이용한 문법관계 분석은 실제 적용시 빠른 수행시간과 적은 메모리 사용으로 상호작용관계 추출에서 효율적으로 사용될 수 있음을 보였다.

영화색채는 서사를 비롯한 영화의 다른 요소들과 동등한 기능을 하며, 표현의 독자성에 따른 텍스트적 의미를 갖는다. 일반적으로, 빨강은 시선을 집중시키는 기능을 하며, 그로부터 유발된 의미는 확산된다. 텍스트와 콘텍스트의 관계에서 집중의 기능과 확산의 의미를 제시할 수 있다. 집중과 확산의 개념은 독자적 색채, 색채와 다른 영화적 요소들의 관계, 색채들 간의 상호작용 등에 따라 구체화된다. 이를 확인하기 위해, 이 연구는 대중성을 담보한 일련의 한국영화를 선정하여, 영화색채가 어떻게 상호작용하며, 특히 빨강의 집중 기능과 확산의 의미가 무엇인지를 분석한다.
