The objective of this paper is to review the mechanics of how global e-trade practices can affect a firm's performance. It is well known that the introduction of global e-trade systems can save transaction costs at the macro level. However this study is extended at micro level by determining whether global trade transaction costs influence positively or negatively in exporting firms performances at firm level. A theoretical framework is suggested for determining the usage and performance of global e-trade with the global e-trade barriers. An empirical analysis of South Korean exporting firms has been undertaken. This paper concludes that the global e-trade has yet to overcome the barriers resulting from the transaction costs and asset specificity. In this regard, appropriate action like intensive education and training program should be implemented in order to make South Korea's global e-trade more matured.

This research verifies the effect on environmental attitude and knowledge accomplishment by t-test as producing and running programs regarding global warming which is raised as a representative environmental issue subject to 6th grade-elementary students. For this, environmental education programs about global warming for elementary students are developed and applied 15 times by reconstituting classes based on the contents regarding global warming from the text books revised as of 7th course of study. The result is as below. First, some part of contents from social study and science of 6th grade elementary curriculum of 7th course of study was able to be reconstituted to 15 education programs. Secondly, the programs about global warming improved students' environmental attitude Application of the programs about global warming showed significant difference(p<.05) on building environmental attitude as it proved those are effective on both area of recognition level and practice level. The method used on the test had .866's Cronbach alpha modulus value therefore, it obtained reliability. Thirdly, the programs regarding global warming improved students' knowledge accomplishment. As a result of test for knowledge accomplishment which was executed with same method for attitude test, the application of the programs about global warming showed significant difference(p<.05) on improving students' knowledge accomplishment on the global warming therefore, it resulted that the application of the program is effective on knowledge acquirement.

Based on the tide gauge data from the Permanent Service for Meau Sea Level (PSMSL) collected at 23 locations in the Korean coast, the long-term sea-level trend was computed using a simple linear regression fit over the recorded length of the monthly mean sea-level data. The computed sea-level trend was also corrected for the vertical land movement due to post glacial rebound(PGR) using the ICE-4G(VM2) model output. It was found that the PGR-corrected sea-level trend near Korea was 2.310 $\pm$ 2.220 mm/yr, which is higher than the global average at 1.0∼2.0mm/yr, as assessed by the Intergovernmental Panel on Climate Change(IPCC). The regional distribution of the long-term sea-level trend near Korea revealed that the South Sea had the largest sea-level rise followed by the West Sea and East Sea, respectively, supporting the results of the previous study by Seo et al. However, due to the relatively short record period and large spatial variability, the sea-level trend from the tide gauge data for the Korean coast could be biased with a steric sea-level rise by the global warming during the 20th century.

The objective of this study is to examine Korean fisheries' globalization level. For that, this paper discusses structural changes of world fisheries and level of korean fisheries' globalization. Fisheries' globalization is measured by comparison of IIT(intra-industry trade) and LIT(level of international trade) on eleven countries(Netherland, UK., USA, France, Japan, Spain, Korea, Taiwan, Thailand, Indonesia, Philipinnes). And analysis data are obtained from UN-UNCTAD PC-TAS and FAO Fishstat. As a result of measure of fisheries' globalization, Netherland is the most globalization country of eleven countries. And the next order is Spain, UK, France, Thailand, Taiwan etc. We can classify these countries into four types. Type I is 'International linkage and integration global indutstry' inculding Netherland, UK, Spain, France. Type II is 'Interantional integration global industry' including Taiwan and S. korea. Type III is 'international linkage global industry' including none of eleven countries. Finally, type IV is 'domestic demand and self-sufficient industry'including Thailand, USA, Japan. So we can name the type of korean fisheries' globalization as 'interantional integration global industry'. Usually this type is evaluated that level of international trade is not high but level of intra-industry trade is high. As a result, from now, we should consider policy directions of korean fisheries whether to decide one of four types or not.

The purpose of this article is to explore recent developments in piracy attacks at the global level. This article provides an overview of global trend of recent piracy attacks and presents global counter-piracy efforts at the international and governmental as well as industry level. The issue of piracy has been a grave concern of the globe, becoming the biggest threat to the safety and security navigation and seaborne trade. Overall, piracy attacks in recent years have greatly diminished owing to multi-faceted counter-piracy efforts. However, Southeast Asia and West Africa have reemerged as an hotspot of piracy. A worrisome trend in these regions is that many of piracy attacks are committed by militant groups for financing their activities. As a result, the level of violence and the sophistication of attacks have escalated. The problem of contemporary piracy is beyond a particular region or coastal state, but a common concern of the international community. In order to address the global piracy problem, international cooperation should be further strengthened at the global level as well as the regional level. As a way of counter-piracy measures in Southeast Asian waters, the creation of a joint regional coast guard to patrol the highly piracy concentration areas needs to be considered.

This paper presents a hierarchical fuzzy motion planner for humanoid robots in 3D uneven environments. First, we define both motion primitives and locomotion primitives of humanoid robots. A high-level planner finds a global path from a global navigation map that is generated based on a combination of 2.5 dimensional maps of the workspace. We use a passage map, an obstacle map and a gradient map of obstacles to distinguish obstacles. A mid-level planner creates subgoals that help the robot efficiently cope with various obstacles using only a small set of locomotion primitives that are useful for stable navigation of the robot. We use a local obstacle map to find the subgoals along the global path. A low-level planner searches for an optimal sequence of locomotion primitives between subgoals by using fuzzy motion planning. We verify our approach on a virtual humanoid robot in a simulated environment. Simulation results show a reduction in planning time and the feasibility of the proposed method.

In this paper, we propose an integrated algorithm for scene recognition, which has been a challenging computer vision problem, with application to mobile robot localization. The proposed scene recognition method utilizes SIFT and visual words as local-level features and GIST as a global-level feature. As local-level and global-level features complement each other, it results in improved performance for scene recognition. This improved algorithm is of low computational complexity and robust to image distortions.

국제가치사슬(Global value chain, GVC)구조가 심화되면서 중간재 무역의 중요성이 커지고 있다. 이러한 배경하에 글로벌 아웃소싱의 확대가 환경에 미치는 영향에 대한 많은 논의들이 최근까지 이어져왔다. 본 연구에서는 2004년부터 2014년까지 10개년 간 21개 제조업 부문을 대상으로 글로벌 아웃소싱이 환경에 미치는 영향을 분석하였다. 환경변수는 업종별 이산화탄소집약도를 사용하였고 글로벌 아웃소싱은 Feenstra and Hanson(1999)과 Amiti and Wei(2006)가 제안한 글로벌 아웃소싱 계측방법을 사용하였다. 글로벌 아웃소싱의 효과를 분석하기 위해 환경변화를 결정하는 요인들을 Copeland and Taylor(1994)의 이론을 기반으로 통제하였고 내생성 문제를 해결하기 위해 시스템 GMM 방법을 이용하였다. 분석결과 전체산업을 대상으로 분석했을 때 글로벌 아웃소싱의 확대가 환경에 미치는 영향을 식별할 수 없었다. 오염집약산업만을 대상으로 분석한 결과도 동일하게 나타났다. 그러나 중국과 아시아 개도국의 아웃소싱에 대해 분석한 결과는 글로벌 아웃소싱의 확대가 국내 오염수준 저감에 영향을 미치는 것으로 나타났다.

제주는 2002년 유네스코 생물권보존지역 지정을 시점으로 15년간 총 5개의 유네스코 등재와 하나의 UNFAO 세계농업유산(GIAHS)에 등재되었다. 제주가 보유한 5가지 유네스코 타이틀은 생물권보존지역(2002), 세계자연유산(2007년), 칠머리당굿 무형문화유산(2009년), 세계지질공원(2010년), 해녀무형문화유산(2016년) 이며, UNFAO의 등재는 세계농업유산 제주밭담(2014년)이다. 이런 세계적 수준의 등재는 고도의 인식과 환경 보호의 가치를 상징하며 더불어 제주방문 관광객을 증가시키고 있다. 그러나, 지금까지 이러한 세계적 유산의 중요성에 비해 제주도민과 방문객 대상의 인식 측정 연구는 매우 부족한 것이 사실이다. 이에 본 연구는 제주도민과 관광객을 대상으로 제주의 세계적인 유산에 대한 인식과 인식 경로, 그리고 로고의 인식 여부와 세계적인 유산 등재에 따른 영향인식에 대해 설문조사를 실시하였다. 그 결과, 유네스코 세계자연유산과 가장 최근에 등재된 해녀 무형문화유산에 대한 제주도민과 관광객의 인식 수준이 가장 높았으며 밭담과 제주 칠머리당 영등굿에 대한 인식 수준은 상대적으로 낮은 것으로 나타났다. 세계유산 로고에 대한 인식 여부에서는 유네스코 로고에 대한 노출이 가장 높은 것으로 나타났다. 이러한 결과를 바탕으로 제주가 보유하고 있는 세계적 자연과 유산의 지속적 보호와 더불어 올바른 홍보 방안의 모색이 필요하다.
