It has great significance to estimate CIF-FOB margins of international trade. It certainly helps develop statistics on transport costs of international trade and provides basic data for econometric analysis of transport costs. It also contributes much to our standing the correlation between the margins and trade partners' geographical distance as well as one between the margins and trading products. However, the quality issue of international trade statistics renders it very difficult to derive trustworthy CIF-FOB margin estimates. Utilizing various analytical approaches, this study intended to acquire credible estimates of CIF-FOB margins for Korea's total imports and for country/product specific imports data. Major findings are as follows. First, the average of CIF-FOB margins of Korea's total imports is 7.3% and is generally declining. Second, country level analysis provides credible estimates for CIF-FOB margins of Korea's imports from four partners (Japan, the US, Australia, and Brazil). The differences in margins among these four countries are caused by geographical distance and characteristics of traded products. Third, product level analysis reveals that the margins of gold and passenger vehicles are fairly low while those of primary products tend to be high.

The purpose of this study is as follows. First we investigate the relationship between contact with foreign managers (CFM) of host country nationals (HCNs) working at MNC subsidiaries and their organizational identification with MNC (OIM). Second we examine the moderating effect of MNC subsidiary localization (MSL) on the relationship between CFM and OIM. For this purpose, we set hypotheses on the relationship among CFM, OIM, and MSL. To verify theses hypotheses, we conducted hierarchical regression analysis on the data from 374 HCNs in 56 MNC subsidiaries. The results of this study are as follows: Frist, CFM positively affects OIM. Second, there is a significant moderating effect of MSL on the relationship between CFM and OIM. Our findings have critical implications in that a subsidiary-level variable that has a significant impact on organizational identification with MNC is presented and in that specific managerial guidelines for subsidiaries can be drawn.

Korea-specific GHG emissions should be estimated correctly in order to ensure effective measurement of climate change variables. The use of country-specific data that reflects fuel and technology characteristics is needed for accurate GHG emissions estimation. Oxidation factors are used to convert existing data into equivalent GHG emissions, and changes in these oxidation factors are directly related to changes in emissions. As such, the oxidation factor is one of the most important variables in using country-specific data to determine GHG emissions. In this study, the oxidation factor of bituminous coal in large scale boilers was estimated using 4,527 data points sampled from eight large-scale boilers that had been using bituminous coal for two years. The average oxidation factor was determined to be 0.997, which is lower than the oxidation factor of 1 that is recommended by the IPCC G/L for large scale boilers when estimating national GHG emissions. However, an oxidation factor less than 1 is assumed for fluidized bed boilers, internal combustion engines, and other small-scale boilers. Accordingly, studies on oxidation factor estimation should be continued to allow for accurate estimation of GHG emissions.

각 국가 권역별 이행실험방법에 따라 지방성 및 고온가열 식품 포장재에서의 시뮬란트별 항산화제와 DEHA의 특정이행량을 비교하였다. 고온 가열용 식품 포장재의 경우 일부 두께가 두꺼운 필름, 예를 들어 PP 필름에서는 각 국가 권역별 시뮬란트 종류와 온도 조건의 차이에 따른 항산화제의 이행량의 차이가 나타났다. 미국이나 유럽연합에서 지방성 식품의 시뮬란트를 이용하여 얻어진 실험치에 $2{\sim}5$의 reduction factor가 계산되는 것을 감안한다면 아시아 조건하에서의 이행치가 유의적으로 높아지는 결과를 초래하게 된다. 아시아의 이행 실험 조건은 해당포장재의 온도 노출 조건에 따라 다양하게 설정될 필요성이 제기되었다.

Purpose - Korean exports account for a vast proportion of Korean GDP, and large volumes of Korean products are sold in the United States. Identifying and characterizing actual and potential product hazards related to Korean products is critical to safeguard Korean export trade, as severe quality issues can impair Korea's reputation and reduce global consumer confidence in Korean products. In this study, we develop country-of-origin-based product risk analysis methods for social media with a specific focus on Korean-labeled products, for the purpose of safeguarding Korean export trade. Design/methodology - We employed two social media datasets containing consumer-generated product reviews. Sentiment analysis is a popular text mining technique used to quantify the type and amount of emotion that is expressed in the text. It is a useful tool for gathering customer opinions regarding products. Findings - We document and discuss the specific potential risks found in Korean-labeled products and explain their implications for safeguarding Korean export trade. Finally, we analyze the false positive matches that arise from the established dictionaries that were used for risk discovery and utilize these classification errors to suggest opportunities for the future refinement of the associated automated text analytic methods. Originality/value - Various studies have used online feedback from social media to analyze product defects. However, none of them links their findings to trade promotion and the protection of a specific country's exports. Therefore, it is important to fill this research gap, which could help to safeguard export trade in Korea.

본 연구는 중국기업의 '일대일로' 연선 국가에 대한 직접투자 전략과 구조를 더닝(Dunning)의 OLI 패러다임 관점에서 분석하였다. 중국기업의 '일대일로' 연선 국가에 대한 투자는 크게 두 가지 전략적 목적에서 추진 되었다. 하나는 '일대일로' 연선 국가의 자원보유 특성상 에너지자원 확보를 위한 투자이고, 또 다른 하나는 중국 국내경제의 문제인 과잉설비 문제를 해결하기 위한 이전(移轉) 투자이다. 중국기업의 이러한 '일대일로' 연선 국가에 대한 투자는 더닝이 OLI 패러다임에서 제기하고 있는 투자 결정 조건, 즉 소유권 우위와 지역특유의 우위 그리고 내부화 우위를 갖춘 가운데 투자를 진행한 것으로 평가된다. 다만 차이가 있다면, 이 지역이 갖는 특수성으로 인해 자원보유 현황 및 제도적 환경의 영향 외에 국제관계의 이해관계 구도, 종교적 갈등 문제와 문화적 이질성 그리고 이 지역 국가들의 중국기업에 대한 인식의 문제 등의 영향으로 투자국가와 투자방식 그리고 투자업종을 달리하고 있다는 점이다.

As a result of the reduction of natural aggregate, most of developed country have been studied the utilization of Blast-furnace Slag(BFS) as aggregate of concrete. bur, in korea there are only basic study about these even though other country are using Blast-furnace Slag production of Ready Mixed Concrete. According, in this study, we carried out fundamental experiments in order to know the material properties of BFS and possibilities of the BFS as fine aggregate of concrete. It is included that analysis concerning material properties of BFS as like specific gravity, absorption. unit weigth, grading including investigation of the surface shape by SEM, also, analysis concerning properties of concrete with BFS as like air-content surface slump. compressive strength .etc.

Dynamic changes in the field of labor relations have become a general trend in the world practice. These changes are due the impact of globalization and technological innovation above all. Concept of "precarization of employment" appeared due the new emerging labor relations. This term has been used for more than thirty-five years, but there is still no generally accepted definition of it. A wide range of authors' viewpoints on problem of precarization makes it vague and impossible to strictly to identify its borders. Features of its manifestations in different countries also complicate the problem. Kazakhstan is a country with export-oriented economy of raw materials. At the same time government try to solve the problem for the industrial-innovative development of the economy. These two factors bring additional specific features in the manifestation of the precarization of employment in the country. The aim of the paper is to identify the features of "precarization of employment" concept in Kazakhstan's practice, based on the proposed definition.

This paper wanted to find out research trends and its determinants on mobile commerce research reviewing 439 articles from 1999, the starting year of this field to 2012. Our analytical framework has 4 categories such as general, technology, consumer and firm, and 14 sub-categories. The results are as follows: First, studies on mobile commerce can be divided into 5 stages. Second, trends of mobile commerce are closely related to the evolution of mobile technologies such as communication technologies and devices (2G, 3G, 3G+, 4G LTE, LTE-A). Third, this field was led by USA until 2005 and has been led by Taiwan after 2006. Fourth, China, Korea, UK and Canada are also leading countries, all of which have mobile device manufacturers. Research trends of non-manufacturing countries and manufacturing countries are different from each other. In addition, the trends of leading countries are different from each other reflecting each country's business needs.
