Objectives: The purpose of the study was to identify the relationships between cybersex addition, loneliness and relationship satisfaction among Korean college students. Methods: 293 students were conveniently selected. The instruments used in this study were cyber-sexual addiction index, loneliness scale and relationship assesment scale. ANOVA, t-test and Pearson correlation coefficient with SPSS 22.0 Version were used to analyze the data. Results: 8.9% of the participants had moderate or severe addiction to cybersex. The level of cybersex addiction is significantly influenced by gender, period of relationship, time taking to sexual relations, contact number of cyber pornography and contact time of cyber pornography. Significant association was observed between cybersex addition, loneliness and relationship satisfaction. Conclusions: The factors mentioned in this study as well as loneliness and relationship satisfaction were important factors. Therefore, future studies on this topics need to develope interventions to reflect cultural and physical character of college students.

본 조사대상 건축물은 부산광역시 해운대구 좌동 1366-3번지에 소재하며, 2001년 3월19일에 준공한 지하 1층, 지상 3층의 철근콘크리트조의 교육연구 및 복지시설로 시공되었다. 본 건물은 현재 내부 벽면에 부분적으로 균열이 발생하는 등 시공상의 부설과, 도면과 실제 시공과의 상이 등의 문제를 안고 있다. 따라서 본 과업은 대상 건축물에 대하여 설계도서 및 정밀 현장조사, 구조계산 등을 통하여 안전성 및 사용성을 평가하고, 부실시공 및 하자 내용을 분석하는데 그 목적이 있다.

Most structures are expected to deform beyond the limit of linearly elastic behavior when subjected to strong ground motion. Seismic evaluation of structure requires an estimation of the structural performance in terms of displacement demand imposed by earthquakes on the structure. Nonlinear time history analysis(NTHA) is the most rigorous procedure to compute seismic performance among various inelastic analysis methods. But nonlinear analysis procedures necessitate more practical and reliable tools for predicting seismic behavior of structures. This paper presents a nonlinear direct spectrum method(NDSM) to evaluate seismic performance of structures, without iterative computations, given by the structural initial elastic period and yield strength from the pushover analysis, especially for MDF(multi degree of freedom) system. The purpose of this paper is to investigate the accuracy and reliability of this method from a point of view of post-yielding stiffness factors.

Recently, a variety of methods are proposed to solve the problems shown in a existing performance-based design of structure. Among those methods, capacity spectrum method(ATC-40, FEMA-273) is one of general methods. The basis of the capacity spectrum method is the idea that the peak response of an inelastic system can be estimated as the peak response of a linear elastic system(equivalent single degree of freedom) with reduced stiffness and increased damping. However, the capacity spectrum method with equivalent SDOF systems characterizing the nonlinear response of multistory structures frequently makes iterative calculations and inaccurate results; and may potentially mislead if higher modes play a significant role in the response. Accordingly, in this study, nonlinear direct spectrum method is proposed and examined as one of methods considering the influence of higher modes to improve accuracy of analysis.
