고하중, 저속에서의 마찰마모특징을 나타내는 건설기계의 작업장치 연결부의 핀/부싱 조인트의 개발 적용성 검토를 위해 기존의 사용방법인 표면경화처리 후 그리이스 급유하는 경우와 ESA(전기방전코팅)처리후 고체윤활제를 도포한 경우의 마찰마모특징을 시험 분석하여 기존 방법보다 ESA처리후 고체윤활제를 도포하는 경우의 마찰마모 특성이 매우 우수한 적을 확인하였다.

This study applied a home therapy convergence program to patients who had undergone mastectomy and examined its effects on their arm functions, occupational performance, quality of life, and depression. The number of subjects was 20. The subjects were those who visited an occupational therapy room as outpatients and received the intervention twice per week, forty minutes per each time, for 12 weeks. In order to look at their arm functions before and after the intervention, K-DASH was employed and their edema was measured with a tape line. In order to examine their occupational performance, quality of life, and depression before and after the intervention, COPM, FACT-B, and BDI, respectively, were utilized. After the intervention, their arm functions significantly increased, but their edema did not significantly decrease, their occupational performance and quality of life significantly improved, and their depression was significantly reduced. Thus, a home education convergence program positively affected mastectomy patients' arm functions, occupational performance, quality of life, and depression.

This study applied an occupation-centered transition program to adults, aged 18 years or more, with intellectual disabilities and residing in a local community, and examined the effects of the program on participants' self-efficacy and social participation. To obtain basic data for the program, 44 adults with intellectual disability were divided into two groups: the experimental group, to which an occupation-centered transition program was applied, and the control group, to which the program was not applied. A self-efficacy scale and the K-Community participation indicators (CPI) were used to assess self-efficacy and social participation, respectively. The results showed that the experimental group showed a greater increase in self-efficacy than the control group (p<0.05). Similarly, a greater increase in the CPI scores was observed in the experimental group than in the control group. The changes in the experimental group were significant (p<0.05), but those in the control group were not. These results suggest that an occupation-centered transition program can improve self-efficacy and social participation in adults with an intellectual disability.

Due to the aging, advancement, and complexity of chemical facilities, non-routine work such as facility inspection, repair, or maintenance work is increasing. Of the 1,483 accidents that occurred over the past 10 years at chemical product manufacturing sites subject to PSM, accidents that occurred during non-routine work accounted for 56% (932 Cases) of the total. It can be seen that more accidents occur during non-routine work than during routine work. In particular, in order to improve the economy and efficiency of factory operation, there are cases where some facilities are stopped without stopping the entire factory and then inspection, repair, or maintenance work is performed while isolated from the operating facilities. Therefore, first, a safe isolation method must be selected by establishing an isolation standard (Baseline Isolation Standard) based on the chemicals handled, operating conditions, and risk level of the equipment in the chemical plant. Second, since current domestic laws and standards do not suggest the need for specific quarantine standards, it is necessary to institutionalize the preparation of quarantine standards. Technical and institutional improvements are needed to prevent fires, explosions, and poisoning accidents caused by leaks of chemical substances.

A lateral load resisting system is a necessary structural element for the mid- to high-rise modular buildings and concrete cores are known as the most typical lateral load resisting systems in 10- to 20-story modular buildings. It is difficult to construct a concrete core simultaneously with the installation and finishing work of modular units because concrete placed using wet methods might contaminate or destroy the modular unit. Therefore, we have developed a hybrid PC (precast concrete) panel construction method that can construct a concrete core together with the installation of modular units. The hybrid PC panel is a load-bearing element in which a pair of C-shaped beams are combined at the top and bottom of a concrete wall. Concrete cores can be constructed by dry method to connect the hybrid PC panels with bolts. In this study, the details and connection of hybrid PC panels are improved to have the lateral performance comparable to reinforced concrete structural walls and are verified through FE analysis.

This study proposed two topical relevance models, simple and complex models, using EEG/ERP techniques. In the simple model regarding simple search tasks, N300 and P3b components are used. The N300 is specific to the semantic processing of pictures and the P3b reflects mechanisms involved in the decision about whether an external stimulus matches or does not match an internal representation of a specific category. In the complex model regarding complex search tasks, on the other hand, N400 and P600 components are used. The N400 reflects activation of an amodel system that integrates both image-based and conceptual representations into a context, whereas the P600 is related to complex cognitive processes. Our research results can be used as a source to design an EEG-based interactive multimedia system.

GEO-KOMPSAT2 shall be designed to produce higher quality of image than that of COMS, and this requires the ground system to provide orbit data with high accuracy; better than 2km which is sort of high accuracy when it comes to geostationary satellite. For GEO-KOMPSAT2, KARI is planning to use ranging data for orbit determination, obtained from two ranging stations located in KARI and oversea country with long longitudinal baseline. This paper estimated achievable orbit determination accuracy using covariance analysis under assumption of using two ranging stations; SOC and available secondary tracking stations located in oversea countries. In addition to covariance analysis, in order to validate the analysis, the Monte-Carlo simulation has been performed and compared to the covariance analysis.

This study aims to examine the present (Western) modern dance by analyzing the works of three choreographers who are currently at the forefront of the dance scene to identify and understand the current choreographic trend. The three selected choreographers for this study are Justin Peck (USA), Sidi Larbi Cherkaoui (Belgium) and Zach Morris (USA). These choreographers were chosen on the basis of their significant identity within the current dance scene. For analysis, one noteworthy works of each choreographer were selected for video analysis. The result of the analysis illustrates that in the current era of promoting technology convergence in the performing arts industry, the three choreographers approach convergence differently by integrating dance and other mediums in their choreography. Peck converges between ballet and the ordinary, Cherkaoui converges between dance and other cultures and Morris converges between dance and venue.
