본 논문에서는 행렬응축기법 및 부구조기법을 이용하여 가변형 입체 복합 공간 구조물을 효율적으로 해석할 수 있는 해석기법을 제안하였다. 최근 구조공학의 발전과 더불어 다양한 사회적 경제적 요구에 의해 가변형 입체 복합 공간 구조물에 대한 연구가 진행되고 있다. 가변형 입체 복합 공간 구조물은 많은 구조부재가 필요 하며, 부재 수가 많아짐에 따라 각 절점이 가지는 자유도수가 크게 증가하여 초기 해석 과정에서 많은 시간이 요구된다. 또한 구조물이 변경되는 경우에는 변경되는 부분의 강성의 변화에 따라 전체 구조물의 강성이 변경되므로 이에 따른 전체 구조물의 재해석 과정이 필요하다. 이러한 점에서 구조물의 자유도수를 줄여주는 행렬응축기법과 반복적인 해석과정을 줄여주는 부구조기법은 가변형 입체 복합 공간구조물을 효율적으로 해석 할 수 있는 방법이 될 수 있다. 본 논문에서는 행렬응축기법과 부구조기법을 이용하여 가변형 입체 복합 공간 구조물을 효율적으로 해석할 수 있는 해석기법을 제안하고, 이를 토대로 구체적인 알고리즘을 작성하였다. 또한 알고리즘을 구체화시켜 가변형 입체 복합 공간 구조시스템에 적합한 구조해석 프로그램을 개발하여 예제 구조물에 대하여 구조해석을 수행하였으며, 구조해석 결과를 상용프로 그램의 구조해석 결과와 비교하여 해석기법에 대한 정확성 및 효율성을 검토하였다.

Hybrid disaster refers to a type of unexpectedly large-scale disaster that results from continuous or simultaneous occurrence of natural and social disasters. Since hybrid disaster is a completely new type of disaster that has simultaneity and continuity, it requires a different management method compared to the conventional disaster management method. Accordingly, this study suggested policy directions for hybrid disaster response system of Korea after reviewing hybrid disaster response systems in developed foreign nations.

전력분야에서의 정보통신의 기능은 전력 계통망과 복합되어 전력시스템 운전에 역할을 담당하고 있다. 정보화사회에서의 전력정보시스템의 중요성과 역할을 다각적으로 고찰하였다. 지금까지 전력 시스템을 지원하는 서브기능으로서 정보통신의 발전을 도모하여 왔으나 새로운 사회에서는 국내적, 국제적 여건으로 보아 공익사업의 경영다각화, 시장개방등에 적극 대처하기 위한 정보통신의 발전을 전력분야 특성에 맞도록 적극적인 추진이 있어야 한다. 이를 위한 공동적 관심 제고와 연구개발 및 설비투자가 과감히 이루어져야 될것으로 생각된다.

The development of Societal and Scientific technologies have increased risk of dysfunction caused by new technologies such as nuclear power, information technology. Also, urbanization and population density is increasing risk to high-rise building fires, traffic accidents, crime and etc. Implementation of wireless communication network on the societal security is very necessary for prevention, preparation and response against these risks. It always consists maintenance, management and the network must be maintained in an emergency. In this paper, we studied the societal security wireless communication network for prevention, preparation and response against complex disasters, and analyzed requirements(essential function, add-ons) for implementation network in the societal security wireless network.

The purpose of this study is to identify the relationships among Social maturity(SM), Self-directed learning(SDL) and Self-concept of professional nursing(SCPN), and influencing factors of SCPN of nursing students. The survey was performed on 221 nursing students in two universities. Data were collected using a structured questionnaires and analysed with PASW 22.0. Study findings revealed that SCPN has a significant correlation with SM and SDL. Major satisfaction(${\beta}=.179$), Meaning on nursing(${\beta}=.274$), SM(${\beta}=.118$) and SDL(${\beta}=.211$) about SCPN were significant predictive variables. This variables accounted for 34.4% of the variance in SCPN. The findings indicate the necessity of developing educational programs to enhance nursing students's SM and SDL for increasing positive SCPN.

Since nursing is carried out in a relationship between nurses and nursing subjects in a social context, the social problem solving ability of nursing college students is very important. The purpose of this study was to identify impact of self-leadership, caring ability and self-efficacy on social problem solving ability in nursing student's. The subjects of this study were 203 nursing college students from a university. Data was analyzed using Pearson correlation and multiple regression. The result of multiple regression indicate that caring ability(${\beta}=0.39$, p<.001) self-efficacy(${\beta}=0.28$, p<.001), self-leadership(${\beta}=0.23$, p<.001) were the most consistent predictors of social problem solving ability and explained 53.0%. It is suggested to establish an autonomy-based program and feedback system and to develop a convergence education program to balance cognitive and emotional aspects.

This study examines effective message strategies that fit with the characteristics of retargeting advertisements, based on the Construal Level Theory. First, we investigate whether the social distance that applies between interpersonal interactions can also be observable in an online environment and test the effects of social distance, depending on the type of online sites. We then examine consumers' construal level when social and temporal distances interplay, and how the effects of the messages change accordingly. As a result, social distance and message construal levels by website type were consistent with existing CLT studies. However, the hypothesis that advertising effects will be higher only when all, multidimensions' distances and construal levels of messages match, was partially supported. Also the current view, that the consumers' evaluations will show no difference to when either or both dimensions are distal, was rejected. Instead, when a discrepancy between temporal and social distance was present, the construal level of the message was more effective when congruent with the social distance out the two dimensions. Hence, it is possible to infer that the influence of psychological distance may vary depending on the dimension of distance.

This study aims to identify determinants affecting on geographic variations in the prevalence of arthritis in Korean women using data mining. Data from Korean Community Health Survey 2012 with 249 small districts were analyzed. Socio-demographic, health behavior and status, and morbidity status measures were analyzed using conventional regression model and convergence analysis method such as decision tree for convergence analysis. Rate of workers in agriculture, forestry, and fishing, salaried workers, persons higher than high school graduates, non-treatment of needing care, non-treatment of care because of economic reason, obesity, heavy drunkers, complaining persons of chewing difficulty, persons with experiencing depression, persons with perceiving stress, and persons with diagnosing hypertension and angina pectoris were variation determinants of prevalence of arthritis in 249 small districts and these districts were classified 10 area groups by decision tree model. Our finding suggest that the approach based characteristics by small area groups rather than national wide or individual level would be effective to reduce in variations of prevalence of arthritis.

This study aims to analyze related laws and institutions and identify research trends and the policy implementation status of the multifunctionalization of school facilities. Beginning in 2001 at Seoul Geumho Elementary School, the enactment of the "Act On The Establishment, Operation And Management Of Multifunction School Facilities" in 2020, was elucidated through the concept and spectrum of the multifunctionalization of school facilities. The relevant research mainly focuses on elementary schools, elderly facilities, and space planning. The Living SOC Project in 2019 acted as a trigger in promoting the multifunctionalization of school facilities as a central government policy. In 2023, the Ministry of Education announced measures and guidelines for establishing the multifunctionalization of school facilities by conducting the project with respect to the "Nulbum School" policy.
