The performance-based design is highlighted as an alternative for the current design method, which cannot definitely specify the performance level that a building requires. Research on it is already in progress, however, in developed countries like the United States and Japan, to establish the basis for a performance-based design. Many studies on such design are also being conducted in South Korea, but South Korea still lags behind other countries in all-around technology. On the other hand, the column members, especially the lower external column, are affected by the variation of the axial force by overturning the moments in the case of lateral loads by earthquake. Varying the axial force can affect the time of local buckling and the ultimate behavior. Thus, in this study, the structural performance, such as the time of local buckling and the ultimate behavior, was analyzed through an experimental study on column members under varying axial force. The feasibility of a domestic study proposing a performance level with a story drift angle formed about a structural-performance-based steel structure design was also verified.

In this work, local oxidation behavior in phosphorous ion-implanted 4H-SiC has been investigated by using atomic force microscopy (AFM). The AFM-local oxidation (AFM-LO) has been performed on the implanted samples, with and without activation anneal, using an applied bias (~25 V). It has been clearly shown that the post-implantation annealing process at $1,650^{\circ}C$ has a great impact on the local oxidation rate by electrically activating the dopants and by modulating the surface roughness. In addition, the composition of resulting oxides changes depending on the doping level of SiC surfaces.

This paper introduces a numerical procedure to incorporate elasto-plastic local deformation effects in the dynamic analysis of beams. The appealing feature is that simple beam type finite elements can be used for the global model which needs not to be altered by the localized elasto-plastic deformations. An overlapping local sophisticated 2D membrane model replaces the internal forces of the beam elements in the predefined region where the localized deformations take place. An iterative coupling technique is used to perform this replacement. Comparisons with full membrane analysis are provided in order to illustrate the accuracy and efficiency of the method developed herein. In this study, the membrane formulation is able to capture the elasto-plastic material behaviour based on the von Misses yield criterion and the associated flow rule for plane stress. The Newmark time integration method is adopted for the step-by-step dynamic analysis.

In this paper, Fundamental rules governing group intelligence "arrangement" behavior of multiple number of autonomous mobile robots are represented by a small number of fuzzy rules. Complex lifelike behavior is considered as local interactions between simple individuals under small number of fundamental rules. The fuzzy rules for arrangement are generated from clustering the input-output data obtained from the arrangement algorithm. Simulation shows the fuzzy rules successfully realizes fundamental rules of the flocking group behavior.

Purposes: This research is an empirical research to analyze the effect of self-leadership on the job satisfaction and organizational citizenship behavior and the mediating effect of psychological capital. Methods: This research investigates the effect of self-leadership and psychological capital on job satisfaction and organizational citizenship behavior of public health workers. The analysis was carried out to 4 local medical staffs in Chungcheongnam-do province, which distributed 330 copies and recovered 313 copies (94.8% recovery) and analyzed 304 copies (effective response rate 92.1%). Findings: First, causality was found in self-leadership and psychological capital. Second, it was found to have a significant effect on psychological capital and job satisfaction. Third, psychological capital was found to have a significant effect on organizational citizenship behavior. Fourth, psychological capital has a positive effect on both Self-leadership's behavior-oriented strategy, natural reward strategy, and strategic thinking pattern strategy. In the job satisfaction relationship, there was a partial mediating effect. Fifth, psychological capital has a positive effect on both self-leadership and organizational citizenship behavioral behavior-oriented strategy, natural reward strategy, and strategic thinking pattern strategy. The organizational citizenship behavioral relationship was found to have a partial mediating effect. Practical Implications: Taken together, the results indicate that the members of the four public health care organizations run by Chungcheongnam-do have a high weight on the natural reward strategy of achieving job satisfaction through the pleasures of doing their favorite activities or jobs.

Information behavior played a significant role in minimizing the risks of the COVID-19 pandemic. When faced with such a situation, an individual needs information for decision-making and in order to determine the best course of action relating to their health. This study aims to explore information behavior during each phase of the COVID-19 pandemic in Indonesia, which is known for its close-knit collective culture. A sensemaking approach is used, which emphasizes the process individuals go through to understand their situation and give meaning to the information they are getting from their environment. Data was collected through in-depth interviews with 10 participants to obtain a description of their information behaviors during the pandemic. Data analysis was carried out using open, axial, and selective coding. We propose a sensemaking-based information behavior strategy framework for mitigating risk and reducing ongoing health crises. Changes in information behavior strategies, including search, prevention, and restriction of information exposure, were random at the beginning of the pandemic, but became more regular in later phases. This was influenced by the "knowledge gap fulfillment" and "use of local knowledge" among the participants throughout the pandemic. In conclusion, the participants developed a sensemaking process including an understanding of the pandemic situation and the risks that they faced. They used a number of information behavior strategies to prevent transmission, and their perception of the risks changed across the course of the pandemic, up til the situation began to be considered back to normal again in Indonesia.

This study is to analyze the Korean translation of "Goseong Chongswaerok" by O Hoeng-muk as a local governor through political ecology. It focuses on how O Hoeng-muk recognized and wrote the interrelation among weather, agriculture, local resident's life, and local policy. The results are summarized in the followings. Firstly, weather was recorded into three types of expression, simple and dynamic expression and agriculture-related expression. Its dynamics was much meaningful and important when weather was related to local resident's life and local or non-local economy and politics. Secondly, weather and local government were conflict under a particular natural condition like severe drought. And society and politics are affected by such a conflict. Thirdly, local people's demonstration was occurred under a certain condition. Bounded agency can be founded in O Hoeng-muk's behavior as a local governor like jinhyul(賑恤), rain rituals, tax collection. Fourthly, the interrelation among weather, agriculture, local people's life, and local policy implemented in a particular local like Goseong ought to be interpreted in terms of multiple scales.
