This papers studies the causalities and effects on the relationship between inbound tourism(TOU) and the production amount of service industry in China, using the unit root test, the Granger causality test, the cointegration test, and VECM. we take their natural logarithm and define them as TOU and SGDP: these represent the distributed variable based the lagged values of the number of international tourists by continent and real production amount in service industry of China, respectively. The results of empirical study of this papers are as follows: Firstly, in the unit root test, we found that each time series was unstable one that has unit root. This result made me use 1st differenced data for this empirical study. Secondly, in the Granger casuality test, the study results show that there is unilateral casuality relation between DLSGDP-$DLTOU_i$ except DLSGDP-DLTOUL model for the same time, while no casuality relation between DLTOU-DLSGDP for all models of China. Thirdly, there is cointegration relation between all models for the period of 1980-2008.

The purpose of this study was to analyze the relationship between hematologic hyperlipemia index and severity of fatty liver abdominal ultrasonography. A total of 412 adults from January 1, 2017 to December 31, 2017 who underwent abdominal ultrasonography and hematologic data within 3 months of the ultrasound examination, were the target of the investigation. As a result of the study, the hematological values according to the degree of fatty liver were statistically significant in triglyceride, AST and ALT (p<.05), fatty liver was associated with gender, triglyceride, AST and ALT (p<.05). In conclusion, the degree of fatty liver was not directly related to the hematologic value of hyperlipidemia, but we confirmed the necessity of co-management with fatty liver and hyperlipidemia by confirming its relevance.

In this study, international standards in disaster management and the management of the relevant International Standards Organizations(ISO), in particular ISO / TC 292 (Security- Safety) research subcommittee to look at international standards of relevant international standards for disaster management trends, each international domestic law related to the standard were researched. National Disaster Management Authority as a Ministry of Public Safety and Security (formerly the National Emergency Management Agency) has continued to prepare a plan for applying national disaster management relevant to the international standards. As the disaster management international standard continues to be established, disaster management agencies need to continue to keep pace with the international community to find ways to introduce international standards.

This study aims at searching the global strategy which can raise the competitive power of IEC(International Express Companies) in Korea analyzing and coping with the international express companies and global factor of promotion. The global strategy varialbe for IEC- invigorating in korea is composed with nine variables which is M&A strategy, Intergrated logistics enterprise strategy, Globalized alliance strategy, SCM stratege, the third party operating strategy, Total logistic operating system strategy, Differentiated service providing strategy, Phased market entry strategy, Core capability strengthen strategy. According to the result of study, the global strategy influence for the nature of international express company's and increasing competitiveness is depend on specialization strategy and using scale of economy for globalization strategy.

Recently, countries on the Caspian Sea were had heavily interested due to instability of international resource market. These countries having been developed basing on energy exports, especially Kazakhstan have drastically grown during a decades. However economy, heavily relied on the exports of energy, is influenced on fluctuation in the international energy price as well as sometimes exposed at Dutch disease. These days, Kazakhstan, increased trade and investment with Korea, has been on the rise as new supplier for energy. Therefore, economic change in Kazakhstan can be an important issue. In this paper, we analyze relations among oil price, interest rate, and real exchange rate during sample period from January 1999 to December 2008 expanding Balasa-Samuelson model. Empirical results present that oil price, interest rate, and real exchange rate mutually keep their balance. Eventually, we find out Kazakhstan has exposed at Dutch disease since oil price and interest rate have negative impacts on real exchange rate respectively.

올해(2004년) 연말로 예정된 남북철도 연결이 동북아 지역의 물적교류에 미칠 영향에 관한 연구는 TSR, TCR. TMGR, TMR에 관한 연구와 함께 국내에 이미 상당한 수준 축척 되었지만 물적교류와 함께 동북아 교류협력에 또 한축을 이루고 있는 인적교류 즉 여객수송에 관한 연구는 거의 없는 실정이다. 본 연구에서는 인구가 조밀하고 경제성장속도가 빠른 서울↔북경 축에 국제 여객열차를 운행할 경우를 가정하여 기존의 항공$.$해운에서 철도로의 수요 전환량을 실제 설문조사를 통하여 구하고 이를 수송할 열차운행 계획을 세운다. 나아가 국제 여객열차 운영자의 입장에서 예상수입 및 비용을 현실성 있게 분석하고 수익성 여부도 유동성, 순현재 가치, 내부수익율 세가지로 검토하여 한$.$중간 국제 여객열차 운행의 가능성을 검증한다.

본 논문에서는 국제우주정거장 (International Space Station; ISS) 개발을 위한 필수 요건인 데이터 인터페이스 기술을 습득하고자, 국제우주정거장에 부착되는 탑재모듈 (Payload)과 인터페이스를 위한 요구사항을 분석/설계하였으며, 이를 검증하기 위한 시뮬레이터의 개발결과를 소개한다. 국제우주정거장과 탑재모듈간의 데이터 인터페이스를 정의하고 구현함으로써, 추후 여러 가지 탑재모듈 개발 시 표준 데이터 인터페이스에 대한 기술을 확보할 수 있으며, 탑재모듈의 특성이나 국제우주정거장의 구체적인 기능에 대한 추가 연구를 통해 탑재모듈 개발 ETB (Electrical Test Bed) 로서의 기능도 수행할 수 있을 것으로 기대된다.
