Recent observation of the neutron star merger event, GW170817, through both gravitational wave (GW) and electromagnetic wave (EM) observations opened a new way of exploring the universe, namely, multi-messenger astronomy (MMA). One of the keys to the success of MMA is a rapid identification of EM counterpart. We will introduce the strategy for prioritization of GW source host galaxy candidates. Our method relies on recent simulation results regarding plausible properties of GW source host galaxies and the low latency localization map from LIGO/Virgo. We will show the test results for both NS merger and BH merger events using previous events and describe observing strategy with our facilities for GW events during the ongoing LIGO/Virgo O3 run. Finally, we report the result of follow-up observation on, the first neutron star merger event, S190425z, during LIGO/VIrgo O3 run.

One of the keys to the success of MMA is a rapid identification of EM counterpart. We will introduce GW follow-up observation project in Korea for hunting GW EM counterpart rapidly and its strategy for prioritization of GW source host galaxy candidates. Our method relies on recent simulation results regarding plausible properties of GW source host galaxies and the low latency localization map from LIGO/Virgo. We will show a test result for both binary neutron star merger events using previous event and describe observing strategy with our facilities for GW events during the ongoing LIGO/Virgo O3 run. Finally, we report the results of optical/NIR follow-up observation of GW190425, the first neutron.

To find out more efficient ways of implementing health promotion programs and to determine the factors affecting the results of various interventions, we reviewed 73 articles un the effectiveness of health promotion programs. These include the papers on the smoking, alcohol, drug abuse, nutrition(obesity) and stress management etc. Specific interventions evaluated in this review are education based on the lecture or video shows, health-related event activities, modifications of policy or the environment, health risk appraisal etc. By using KIHASA Line of Korea Institute of Health and Social Affairs, National Congress Library Database MEDLINE, we identified 201 articles published from 1980 to Jun. 1979 and finally selected 73 papers which contain the implementation process, and result of each program. The factors used in the analysis of the programs are (1) characteristics of participants (2) interventions evaluated (3) research design (4) length of programs and evacuation point (7) outcome indices (6) effect of program evaluated by each author. The study results did not prove positive effect of education based on lectures or video shows etc. Rather, it was suggested that lecture-based education has negative effect on the result. Event activity such as contest or health festivals has positive effect, and policy change or environmental change is closely related to the event activity. Also, the result shows that the overall effect of programs fur the students is less than that of the programs for the others. The programs conducted over, 1-year are mere likely to have positive outcomes than shorter ones. And, the outcomes of the programs with controlled research design such as experimental or quasi-experimental study tend to be evaluated inferiorly to those with non-experimental design.

This study identified the important service quality of the emerging night market as an alternative for the revitalization of the traditional market. This study also was to analyze the effects of service quality on customers' emotions, behavior intention and local performance in night market, and to provide an effective operation plan. The collected data were analyzed by frequency analysis, factor analysis, reliability analysis and multiple regression analysis using SPSS 16.0 Version, a statistical package program, and various results were discovered. First, all the service quality factors (convenience, food, event program, physical environment) had a positive (+) effect on positive emotion, and the service quality factors except event program had a negative (-) effect on negative emotions. Second, the service quality factors had a partially positive (+) effect on behavior intention and local performance. Third, the positive and negative emotions had a effect on behavior intention, however, the positive emotions had a positive (+) effect on local performance. Consequently, the present study confirmed that service quality in the night market is important factors for emotions, behavior intention, and local performance. Therefore, the findings of this study is capable of being the basic data for revitalizing the traditional market in the future.

The purpose of this study is to consider activation methods of traditional markets in Jinju city through questionnaire and field survey. Research framework is summarized into two categories: physical environment and operation program. The results are as follows: 1) the gross profit on sales has been decreased continuously and the main causes of that have been recognized as insufficiency of parking lots and convenient facilities and deterioration of environment in spite of facilities modernization project; 2) consumers visited a traditional market because of proper price and reliance on goods, etc. However, they were not satisfied with the physical environment such as parking lots and resting spaces and the operation program such as cultural event and performance. In conclusion it was thought that activation methods of traditional market would be related to the improvement plan in the physical aspect such as parking lots, walkway, convenient and crime prevention facilities and in the operation program aspect such as cultural event, marketing, management consulting, information infrastructure, and delivery system.

이 논문에서는 병행 프로그램을 테스팅하기 위해 오토마타에 기반을 둔 새로운 결정적 수행방법을 제시한다. 이 논문에서는 제안한 방법은 부분 순서 방법에서 상태 폭발 문제를 해결하기 위해 사용되는 이벤트 독립 개념을 사용하여 주어진 이벤트 시퀸스와 의미적으로 동일한 시퀸스들을 받아들이 수 있는 오토마타를 구축한다. 따랏 프로그램이 주어진 시퀀스를 직접적으로 구현하지 않았다 할지라도 그 와 의미적으로 동일한 대안 시퀀스가 존재한다면 프로그램의 실행을 허락한다. 이 방법의 장점을 프로그램이 명세에 기술된 대로 정확하게 구현되어있지 않은 상황에서도 적용할수 있다는 점이다.

Flight data from operational quality assurance programs plays a significant role in identifying factors as one of the key data in the development of proactive and preventive aviation safety management technologies based on data. The list of events in the flight quality assurance program recommended by the FAA differs from the list set and managed by airlines themselves and is based on the frequency of occurrence rather than the severity of individual events. In this work, we compared the list of FOQA events presented by the FAA with the list of some domestic airlines. We also investigate the severity priorities of events for airline captains and conduct research on how to improve the operation of the operational quality assurance program.

Modelling and Simulation of the activation process for the myocardium is meaningful to understand special excitation conduction system in the heart and to study cardiac functions. In this paper, we propose two dimensional cellular automata model for the activation process of the myocardium and simulated by means of discrete time and discrete event algorithm. In the model, cells are classified into anatomically similar characteristic parts of heart; SA node, internodal tracks, AV node, His bundle, bundle branch and four layers of the ventricular muscle, each of which has a set of cells with preassigned properties, that is, activation time, refractory duration and conduction time between neighbor cell. Each cell in this model has state variables to represent the state of the cell and has some simple state transition rules to change values of state variables executed by state transition function. Simulation results are as follows. First, simulation of the normal and abnormal activation process for the myocardium has been done with discrete time and discrete event formalism. Next, we show that the simulation results of discrete time and discrete event cell space model is the same. Finally, we compare the simulation time of discrete event myocardium model with discrete time myocardium models and show that the discrete event myocardium model spends much less simulation time than discrete time myocardium model and conclude the discrete event simulation method Is excellent in the simulation time aspect if the interval deviation of event time is large.
