Purpose: The purpose of this study was to investigate the affect of eating behaviors on subjective health of multi-cultural adolescents in South Korea. Methods: This study is designed as cross-sectional. Using the statistics from the 15th (2019) Korea Youth Risk Behavior Web-based Survey, multiple logistic regression analysis was conducted. Overall, 711 multi-cultural adolescents were included in the analysis. Results: When analyzing the factors affecting the subjective health status of multi-cultural adolescents, normal body mass index (OR: 0.56, 95% CI: 0.35~0.89) and milk consumption (OR: 0.54, 95% CI: 0.35~0.83) showed a lower risk of being unhealthy, while skipping breakfast for 5 days (OR: 1.97, 95% CI: 1.33~2.93) and convenience store food consumption (OR: 1.59, 95% CI: 1.05~2.40) showed a higher risk of being unhealthy. Conclusion: It is necessary to form positive eating habits that influence the subjective health perception of multi-cultural adolescents. Therefore, appropriate dietary education and systematic support should be provided for multi-cultural families.

Purpose - These days, Korean society with more than 2 million foreigners has made multi-cultural society quickly. Multi-cultural society has become popular and anti multi-cultural phenomenon has grown up gradually against Korea's traditional habits. Research design, data, and methodology - European countries that were said to be multi-cultural society had suffered from terror, riot and other social conflicts. The study examined Koreans' racism and anti multi-cultural emotion to investigate the conditions and causes of anti multi-cultural emotion. Further, this study investigates a prevention of the worst case such as Norway terror and the countermeasures compared to each country's social customs. Results - Koreans are not generous to the foreigners. Foreign countries' cases after failures in multi-cultural society might give future implications on multi-cultural society in Korea. Conclusions - Korean society have not produced new one by introducing another races, nationality and culture not cognizing failure experiences of multi-culturalism like Europe. Nonetheless, Korean society shall not give up multi-culturalism. Korean society shall prepare for multi-culturalism society to lessen social conflict as much as possible and not to neglect anti culturalism emotion producing social conflict, and shall investigate the related causes to lessen anti multi-culturalism emotion and to integrate Korean style of multi-culturalism society for Korea as a tool of nation management.

The purpose of this study is to investigate specific crowding areas resulted from diverse physical factors of multi-plex theaters in a fire evacuation, and more accurately predict the evacuation route of people. To achieve these purpose, the architectural characteristics of three multi-plex theaters in Jinju have been chosen, and the evacuation experiments through the computer simulation called Simulex were carried out for each on the these theaters. The conclusions from this study are as follows: (1) Crowding usually happens cross areas between theater inside and corridors, and Crowding rate depending on the number of cross areas. (2) It is necessary to design the escape routes being employed ordinary times. And the egress routes planning should be integrated into space programming at the early stage of building design.

초기 전자악기를 만드는 사람들은 자신들이 직접 만든 터치 장치를 사운드 조절에 이용하였다. 1982년에 첫 멀티터치 시스템이 등장하면서 21세기 초까지 관련된 많은 연구가 진행되어 멀티터치 시스템의 성능은 빠른 속도로 향상되었다. 이러한 성능 향상에도 불구하고 멀티터치 인터페이스의 대중화의 길은 요원해 보였다. 그러나 2007년 애플의 아이폰을 시작으로 멀티터치 인터페이스는 큰 인기를 끌게 되었고 스마트폰을 통해서 대중들이 멀티터치 인터 페이스의 특징을 보다 쉽게 체험 할 수 있게 되었다. 이러한 흐름 속에서 멀티터치 인터페이스는 자연스럽게 사람들의 주목을 받으며 다양한 가능성을 보이고 있지만 관련 콘텐츠의 부재와 개발 인프라의 부족으로 인해 대중화의 길로 다가서기에는 여전히 부족한 현실이다. 본 논문에서는 현재의 멀티터치 인터페이스의 문제점을 지적하고 멀티터치 인터페이스 시장의 활성화와 멀티 터치 관련 콘텐츠 제작자를 위한 범용 멀티터치 인터랙션 시스템을 제안한다. 실험을 통해 제안한 시스템의 효율성을 입증하고 나아가 멀티터치 콘텐츠 시장이 발전할 수 있는 방안을 제시한다.

The finite element programs have been developed for structure, collision, flow, dynamics, heat transfer, acoustics, electromagnetism, MEMS (Micro Electro Mechanical Systems), and etc. These programs can be classified as either "package" program or "single purpose" program. Single purpose programs usually have convenient and powerful functions, but these programs have limited expandability to different fields of analysis. Therefore, the method to converter the analysis results of single purpose program to other programs is needed. In the research, multi-body data conversion methods of 1) finite element model and 2) solid model were created to convert fluid analysis result of CFD-ACE+ to ANSYS data structure. Automatic boundary condition algorithms were developed for blade, and finite element model was compared with solid model. It is expected that, by sealess data transfer, the Multi-body Data Conversion Program could reduce the development period of torque converters.

A multi-purpose sensor interface that provides dual-mode operation of fingerprint sensing and physiological signal detection is presented. The dual-mode sensing capability is achieved by utilizing inter-pixel shielding patterns as capacitive amplifier's input electrodes. A prototype readout circuit including a fingerprint panel for feasibility verification was fabricated in a $0.18{\mu}m$ CMOS process. A single-channel readout circuit was implemented and multiplexed to scan two-dimensional fingerprint pixels, where adaptive calibration capability against pixel-capacitance variations was also implemented. Feasibility of the proposed multi-purpose interface was experimentally verified keeping low-power consumption less than 1.9 mW under a 3.3 V supply.

The purpose of this paper is a study on getting proper gain set of PID controller which satisfies multi-performance specifications of the control system. The multi-objective optimization method is introduced to evaluate specifications, and the genetic algorithm is used as an optimal problem solver. To enhance the performance of genetic algorithm itself, adaptive technique is included. According to the proposed method in this paper, finding suitable gain set can be more easily accomplishable than manual gain seeking and tuning.

The water treatment by was performed to remove VOC and organic substances in the multi-stage ozone contactor. Ozone is mainly utilized to change the chemical structures of organic substance, of which finally has the purpose to degrad them. The removal efficiency of VOC has 20~60% at the ozone concentration of 3 ppm, in case of trichloroethylene, its efficiency is reduced by 85% at the ozone contact time of 8 min. Design factors such as the number of stage, ozone concentration, zone contact time are determined for optimal treatment in the multi-stage contactor.
