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 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.

In the 21^st century, the growing use of information and communication technologies (ICTs) and social media platforms has influenced our way of life, including international diplomacy. With the use of new interactive communication technologies such as WhatsApp, Twitter, Facebook, Instagram, video sharing website, blogs, and other social media networks, digital diplomacy has become an active diplomatic mode in modern society and plays an increasing important role in international relations. Although Indonesia has gradually realized the pivotal role of internet diplomacy and recently put it into practice, it is still lagging far behind. This paper will examine how Indonesia conducts its diplomacy in the new era of digital world. How far and in what ways does the Indonesian government make use of digital technology to conduct its diplomacy? What opportunities and challenges are confronted to develop digital diplomacy? How does it navigate diplomacy in the digital age? Unless Indonesia embraces new channels and methods of diplomacy, its foreign policy implementation may not run optimally to support its aim of attaining its objectives in the international stage.

This research examined consumption-based carbon emission reduction by nuclear energy consumption and environmental tax while considering the context of trade globalization in the highest five emitter nations from 1990 to 2020. This study used various empirical methodologies, including preliminary analysis to check the stationarity and cointegration, the CS-ARDL for long-run analysis, CCEMG, AMG for robustness, and the D-H causality test for short-term pairwise causation. The results indicated that nuclear energy consumption, environmental tax, and trade globalization help to mitigate consumption-based carbon emissions while economic growth and population density boost carbon emissions. Furthermore, the results also found two-way casual connection exists between nuclear energy consumption, population density, and consumption-based carbon emissions. Thus, the results emphasize the need for government policies that encourage nuclear energy and environmental tax as a strategy to reduce carbon emissions and achieve and maintain environmental development.

단차로 하이패스시스템의 지 정체로 인한 교통 혼잡, 안전사고, 유지보수 등 매년 발생하는 문제를 해결하기 위해 무정차 다차로 고속주행기반 시스템의 개발이 필요하게 되었다. 하이패스 통신시스템은 단차로 환경에서 선입선출 방식이므로, 다차로 환경에서 발생하는 군집주행 및 차로전환 등 다양한 주행패턴을 처리할 수 없다. 본 논문에서는, 기존의 하이패스 단말기를 수용하면서 다차로 주행이 가능한 통신시스템을 개발했다. 능동형 RF/IR 통신 안테나를 이용해 중첩 영역은 넓히고, 오류범위를 최소화 하는 기술을 구현했다. 체험도로를 다차로 실 환경처럼 구축하여 테스트한 결과 하이패스시험기준을 통과했을 뿐 아니라, 속도별, 차로별, 차로전환별 주행시험 및 단말기 위치별 시험 결과 통신 정확도도 99.9%로 하이패스시스템의 성능을 만족했다. 무정차 다차로를 위한 통신시스템은 향후 고속도로 및 유료도로에서도 사용할 수 있을 뿐 아니라, 주차장에서도 활용할 수 있을 것으로 기대한다.

The persent study aims at finding out a means of prevention cool spell damages on the hilly areas. The irrigation plots of 24 hour stored water warm water way and warm water plots, cool water way are respectively established to find out water temperature and influnce on the growing rice plants. The results obtained are summed up as follows. 1. Warm water areas consisted of $5 m^2 Q=0.93 1{\ell}/sec$, V=31 cm/sec, S=1/1, 000, L=81.6m, B=5cm, h=6cm, t=4min 33sec, drops=9 areas, are constructed to help the water temperature of $14.5^{\circ}C$ rise to that of $21.6^{\circ}C$. This indicates lower temperature than $23^{\circ}C$ of critical water temperature in irrigation facilities by $1.45^{\circ}C$ and than $26.2^{\circ}C$ of balanced water temperature of Seoul arears by $4.6^{\circ}C$. But this does not give much influance on rice plant cultivation. 2. The rising of water temperature is influened according to the temperature, solar radiation but the water temperature changes according to the heat absorption of organized materials, weather and terraces. The difference of water temperature could be found in the first growing stage. 3. Through the warm water way of water rises to the temperature of $21.6^{\circ}C$ which also rises to the temperature of around $30^{\circ}C$ in the paddy field of submerged irrigation. The rice plants are comparatively free from prolonged cool damage, reproduction abstructive damage. 4. The water temperature in rice field in proportion to temperature influence of weather condition but the water temperature approaches to that of weather in the days of later growing stage and water temperature become lower than the air temperature in the fruit stage. 5. The water in the submreged field is $10^{\circ}C$ warmer than in the warm water way during the first growing stage period but the water temperature in the warm water way is warmer in the later growing stage period. The cool water of $14.5^{\circ}C$ is warmed to $30.1^{\circ}C$ and rice plants cultivation is free from other damages. 6. The 12% increased production or 570.98kg/10a is made cool water plot by rising the temperature of water from $14.5^{\circ}C$ to $21.6^{\circ}C$ making the water run through warm water way. 7. The damage inflicted by the cool water irrigation during the first growing stage period is the obstruction of peak tillering stage and the obstruction of heading the later growing stage period and the obstruction of fruiting and number of panides per fill.

We desperately recognize from the economic situation in IMF crisis that only competive goods and serviced. It is anticipated that this difficult situation will probably be continued till 1999. Therefore, it is necessary to think over real aspects of eating=outdoors in IMF period and to provide an opportunity to confront with this crisis. Analysis a recent tendency of domestic eating-outdoors business, there appears, first of all, dual types of eating-outdoors; the one is a sort of 'Cost Sale', which provides some special menu with lowest prices, and the other is a type of 'Family Restaurant', which regards the atmosphere of the place as one of the most essential elements. Both types are getting more popular today. As the result, neither of the alternative cannot recover the current Depression. It is natural that no other conditions can compete with good tastes, fancy atmosphere, and good prices. As a matter of fact, however, it is quite difficult to run this type of bussiness adjusted the above whole conditions. Therefore owners of eating-house must decide to run either ' Cost Sale' or 'Family Restaurant' first and investigate some problems and conditions accordingly. In ane way, the owner intensively visits to some eating houses which is similar style in size and management to that of his style in size and management to that of his and look over what is good and what is bad Right after this investigation, it is efficient for he or she to improve his or her business style in size and management in a short period. It is helpful to check some complements; improvement of signboards, cleaning up of the interior, selecting suitable menu, adjusted prices, tastes, and service quality etc. Although eating-outdoors business is hard hit by IMF, We hope that it would rapidly be brisk in 2000, becaused by that time the basis of each industry would be high qualified, and rich technology would be accumulated.

바이너리 코드 수준에서 정적인 프로그램 분석을 수행한다. 소스 코드가 아닌 바이너리 코드 수준에서 분석을 수행하는 이유는 일반적으로 로컬 컴퓨터에 설치하는 실행 파일은 소스 코드 없이 단지 바이너리로 된 실행 파일만 주어지는 경우가 대부분이기 때문이다. 또한 정적으로 분석을 수행하려는 이유는 정적인 제어 흐름 분석을 통해 프로그램이 수행 시 어떤 동작을 수행하게 될지를 수행 전에 파악하기 위해서이다. 본 논문에서는 바이너리 실행 파일로부터 함수간의 실행 순서 및 제어 흐름 등의 정보를 표현할 수 있는 실행 흐름 그래프를 작성하여 사용자가 바이너리 파일의 실행 흐름과 위험한 함수의 호출 여부를 동시에 파악할 수 있도록 하며, 그래프를 통해 바이너리 파일의 분석을 용이하게 한다. 또한 실행 흐름에 대한 자동 탐색 방법을 제공하여 수행될 프로그램의 안전성을 보장하고, 수행 전에 외부에서 다운받아 설치할 프로그램이 안전한지를 판단할 수 있도록 한다.

Objectives : Shanghanlon is based on the Hwangjenaegyeong(黃帝內經)'s theory. Therefore, the contents of the Naegyeong can interpret Shanghanlon's provision, Chengwuji(成無己) followed the same way. Therefore, I studied the relationship between the symptom of Shanghanlon and the defensive Gi(衛氣), I try to prove that the Naegyeong is the theoretical basis of Shanghanlon. Methods : Naegyeong explains that defensive Gi protects the outer parts of the body, and runs the outer parts of the body. So I will explain the spontaneous sweating(自汗) aversion to cold(惡寒) pain(痛症) fever(發熱) difficulty of urination(小便不利) using the function of defensive Gi. Results & Conclusions : The defensive Gi and the nutrient Gi(營氣) run together, if the defensive Gi is weak, can not protect the nutrient Gi. If the defensive Gi does not perform the function of inducing astringency(固攝), the symptom of spontaneous sweating appears. If aversion to cold is caused by the weak of defensive Gi, we use the treatment of warming the Yang(溫陽). If aversion to cold is caused by the defensive Gi can not run, we use the treatment of activating the Yang(通陽). If the Gi and Blood(氣血) is not feeding properly, the pain occurs. In this case, we use the treatment of activating the Yang(通陽). The fever is caused by the stagnation of defensive Gi. If the defensive Gi is weak, the symptom of difficulty of urination appears.
