최근 건설공사에서 많은 물량이 투입되는 기초구조의 자재비 및 원가절감을 위해 여러 가지 기초구조시스템이 개발되고 있으나, 보편적으로 현장에 적용하기에는 다소 무리가 있는 것으로 지적받고 있다. 본 연구는 강판을 ㄷ자형으로 절곡한 기초전단보강시스템을 개발하기 위한 해석적 연구의 일환으로 진행되었다. 현행 전단머리 보강식에서는 기초판에 대한 전단내력 산정을 위한 기준식이 마련되어 있지 않으며 플랫플레이트 슬래브의 기준식에 따르도록 되어져있다. 그러나 기초판은 지반에 지지되는 구조물로 플랫플레이트 슬래브와는 경계조건이 다르다. 따라서 본 연구에서는 지반에 지지된 경우와 플랫플레이트 슬래브와 같이 모멘트 제로지점을 단순지지한 형태로 기초구조물을 모델링하여 해석을 실시하였다. 해석프로그램은 유한 요소기법이 적용된 ABAQUS를 사용하여 두 지지조건의 차이가 구조물에 미치는 영향을 비교분석하였다.

헬리컬파일은 한 개 이상의 나선형 원판이 고강도 강관 파이프에 부착된 말뚝이다. 기존의 헬리컬파일은 커플러 형태의 연결방식을 사용하였으나, 볼트 구멍과 볼트사이의 유격 및 연결소켓과 강관 사이의 유격등으로 인한 높은 지지력 기대가 힘들었다. 본 연구는 헬리컬파일 연결방식 개선을 위해 기존 커플러형식에서 플랜지 형식을 적용하였고, 정재하시험을 통해 지지력을 비교 분석 하였다. 정재하시험결과 플랜지 형태의 연결방식이 커플러 형태의 연결방식보다 높은 지지력이 발휘되었고 플랜지형태 적용시 상향식그라우팅이 가능하여 품질이 향상되었다. 또한 연결부 유격을 방지 할 수 있었다.

This paper presents the application of the technique of differential transformation to find the vibration frequencies for inhomogeneous beams with one sliding support, the other clamped and the other pinned boundary conditions. Numerical calculations are carried out. The frequencies obtained from the differential-transformation solutions are compared to published results to demonstrate the accuracy and flexibility of the method.

The purpose of this study was to investigate the actual conditions of successful ageing and the influencing factors focusing on social support from family and friends to improve elderly's quality of life. The 300 respondents, all participants in programs at facilities for the elderly, were interviewed via a questionnaire. The collected data were analyzed using SPSS 23.0. The results are as follows. First, the average score for successful ageing among the participants was above average. Second, the level of successful ageing varied according to income and religion. Third, the common variables affecting active or emotionally successful ageing were support from friends, subjective health conditions, and gender. It is suggested that the community should be informed of the importance of support from family through educational programs, as the elderly still want the support of family despite family's reduced role.

본 연구의 목적은 첫째 창업자가 창업을 함에 있어 창업준비를 통해 창업성과에 미치는 영향관계와 본질적으로 항상 내재되어 있는 실패에 대한 두려움 요인이 창업성과에 미치는 영향 관계를 실증 검증하고자 한다. 두 번째로 상반된 개념의 독립변수가 동시에 종속변수에 미치는 영향을 알아보고 이에 따라 변수간의 상관관계를 분석하고, 사회적지지를 조절변수로 하여 창업준비와 창업실패에 대한 부담감에 조절효과가 있는지 검증하고자 한다. 따라서 본 연구의 의의는 창업준비와 창업실패 부담감이 창업성과에 영향을 미치는 요인들에 규명하고 사회적지지의 조절효과 요인을 분석하는데 있다. 연구의 학문적 함의점은 주요 많은 국내문헌에서 창업실패감과 창업의지에 관한 연구중심에서 벗어나 창업준비와 실패에 대한 부담감이 창업성과에 미치는 영향을 직접적으로 검증하는데 있다. 또한 창업자들이 인식하고 있는 창업준비와 창업실패에 대한 부담감이 창업성과와의 영향관계를 파악하여 구체적인 실무적 시사점을 제공할 수 있다.

메타버스의 산업적/학술적 가치가 증대되면서, 실세계 인간과 메타버스 내 디지털 휴먼과의 상호작용 시스템 또한 큰 조명을 받고 있다. 본 논문에서는 인간과 디지털 휴먼이 상호작용할 때, 인간의 발화에 대해 감성적 지지가 가능한 디지털 휴먼 프로토타입을 소개한다. 대화의 의미에 따른 동작 생성이 가능한 아바타 구축 공개 프레임워크를 도입하고, 사전학습모델을 바탕으로 감성적 지지가 가능한 심층 대화 생성 모델 기반 대화 시스템을 여기에 통합하여 인간의 감성 상태에 따른 동작과 대화를 진행하는 감성 지지형 디지털 휴먼 프로토타입을 구현하였다. 이러한 프로토타입을 고도화 하면, 향후 메타버스 기반 정신 건강 케어 및 디지털 치료제로의 확장이 가능할 것으로 사료된다.

Objectives: This study was performed to investigate the levels of psychosocial stres and to identify its Methods: The study subjects were 1,806 adults aged 40-70 years living in Naju City, Jeollanamdo. Sociodemographic characteristics, health-related behavior, social suport and personality were collected for statistical analysis. The measurement instrument of psychosocial stress was psychosocial well-being index. The regression analysis. Results: The results showed that 16.6% of subjects were categorized as high stress, 63.4% as moderate, and 20.0% as normal. Overall, the mean value of PWI was 17.29.8 and significantly diferent by socioeconomic characteristics, health-related behavior, social suport and personality. In the case of men, the income, decreased positive social suport, increased negative social suport, type A behavior pattern, decrease of internal locus of control or poorer self-esteem. In the case of women, the PWI was significantly deteriorated in the subjects with no job, no spouse, decreased positive social suport, increased negative social support, type A behavior pattern, decrease of internal locus of control or poorer self-esteem.Conclusions: The psychosocial stres for rural residents was related with social suport and personality. Thus, these results should be considered to reduce stres levels in rural adults.

The main objective of this paper is to analyze the rectangular stiffened plates with two opposite ends elastically restrained and the others simply supported subjected to in-plane bending by Finite Element Method. Another objective is to develope Classical Method analyzing the unstiffened rectangular plates with the above boundary conditions. In order to validate finite element and classical methods, the buckling strengths of the rectangular plates with four simply supported ends, and with two simply supported and the others fixed ends by finite element method and classical method are compared with those of references. In finite element method, elastically restrained ends can be obtained as considering torsional and warping rigidities of end stiffeners. The buckling strengths of the rectangular plates with elastically restrained ends by finite element and classical methods are calculated and compared with each other. In case of stiffened plates, to validate finite element method, the buckling strengths of the rectangular stiffened plates with four simply supported ends, and with two simply supported and the others fixed ends are also compared with those of references. The buckling strengths of the rectangular stiffened plates with elastically restrained ends by finite element method are calculated as solving eigenvalue problems which are obtained as assembling rectangular plate elements and beam elements considered torsional and warping rigidities. The buckling strengths of rectangular stiffened plates according to various positions of rectangular intermediate stiffener, J and I/sub w/ of end stiffeners are also obtained, which are compared to determine the efficient position of intermediate stiffener.

This study intends to explore structural characteristics of social networks for female immigrants married to Korean men, and to analyze the relationship between the characteristics and types of social supports provided by their social networks and the differences between support-giving and support-receiving networks. Ego-centered network analysis is used for collecting network data on fifty-three migrant wives selected by a snowball sampling method. Results show that social support receiving and giving networks of female immigrants have similarities rather than differences, which implied that they play roles not only as support receivers, but also as support givers in their social networks. Also the study suggests that there are correlations between networks' characteristics, such as density and effective size of ego network, and types of supports. The result indicates that the less cohesive and less redundant ties female immigrants had, the more diverse and more informational and emotional supports they obtained from their social networks. Due to the sampling method and size, this study has a limitation to generalize the results for the whole population of female immigrants in Korea. However, it provides a basic understanding of female immigrants' social networks.

This study was to investigate the relationship among emotional intelligence, social support and parent-child communication of multicultural primary school students in rural areas. All of the students for the study were sampled from three multicultural primary schools in rural areas. About 10% among them were from multicultural family students. First, the result indicated that students' emotional intelligence was positively correlated with social support and open communication with their parents. Second, there were no significant differences between unicultural family and multicultural family in social support, parent-child communication, and emotional intelligence. Third, the result of regression analysis revealed that peer and family support were predictors of emotional intelligence of multicultural primary school students in rural areas. The implications for the improvement strategy for multicultural primary school in rural ares were suggested.
