카자흐스탄은 한국의 기술과 문화에 대해 높게 평가하고 있으며 한국을 자국 경제발전의 롤모델로 인식하고 양국 간 관계를 전략적 동반자 관계로 격상시키는 한편 협력 분야를 에너지, 자원 분야에서 기초과학과 IT 분야로 확대하고 있다. ICT는 카자흐스탄이 산업 다각화를 위해 전략적으로 육성하고자 하는 분야로 막대한 ICT 프로젝트를 제시하며 세계적인 경쟁력을 가진 우리 ICT 기업의 투자와 참여를 적극 요청하고 있다. 카자흐스탄과는 과거 (주)대우의 카작텔레콤 인수를 시작으로 ETRI의 우정, 이러닝 등 기술 지원 사업과 정책자문 등 다양한 협력 사업 경험을 가지고 있다. 그러나 양국 정부의 지원을 바탕으로 협력 사업을 진행하는 공공기관이나 충분한 자체 사업 역량을 보유한 대기업에 비해 모든 면에서 열세인 중소기업은 정확한 정보를 바탕으로 구체적인 전략을 수립하고 현지에 진출해야만 성공할 가능성이 높다. 따라서 본고에서는 우리 ICT 기업의 카자흐스탄 시장 진출을 지원하기 위한 사전 연구로서 ICT 시장 현황을 파악하고 현지 시장 진출 시 고려해야 할 요인들을 소개하고, 전략적 접근 방법을 제시하고자 한다.

This study deals with the regulatory policy of government on the convergence of broadcasting and telecommunication by applying rent seeking theory to Internet Protocal TV (IPTV). Existing literature has mainly focused on the negative implications of rent seeking since Tullock [1967], Krueger [1974] and Buchanan [1980]. We have investigated the regulatory policy along with the progress of the convergence of broadcasting and telecommunication. Regulatory policy on broadcasting, despite its impartial intent. has created the entry barrier in the industry, resulting in high rents. Meanwhile, regulatory policy in telecommunication is more geared by the encouragement of more competitive environments, resulting in reasonably low rents in the market. Regulatory policy in the age of convergence needs to improve the efficacy of the industry and welfare, while maintaining the rent at a reasonably low level. This research has contributed to emphasizing the positive aspect of rent seeking in policy concerned with the convergence of broadcasting and telecommunication, notably IPTV.

The study is based on the elaborated normative and legal documentation regulating the national security of modern Ukraine and the normative and legal documents adopted by NATO in the responding policy to the challenges that arose after 2014. The main advantages of cooperation with NATO are ensuring military security, developing army standards, improving the country's investment climate, and reducing expenditures on the army. The disadvantages of cooperation with NATO in hostilities with Russia are not highlighted. Still, defined obstacles show that Ukraine is not ready to realize entry into NATO in the short term. Such factors include weak information support, corruption, and unclear diplomatic decisions.

Aspiration, the entry of material into the airway below the true vocal folds, has been reported in various type of postsurgical head and neck patients. The important of correctly identifying the cause of aspiration in the head and neck surgical patient. Clearly each cause represents a different physiologic or anatomic disorder which requires different management strategy. We discuss about the cause of aspiration during head and neck treatment.

This study analyzes factors that affect the corporate value of Korean companies operating in Latin American countries. Primary factors are associated with characteristics of the host country, the parent company, and subsidiaries. Empirical results show that asset specificity is the main factor influencing firm value. This region is geographically far from Korea and culturally different. Therefore, the source of competitive advantage such as asset specificity should be large enough to offset liability of foreignness for successful entry into the region. This paper also found that joint ventures are more advantageous than direct investments. Joint ventures in Latin American can minimize risk, complement technology and information, and reduce trade barriers.

본 논문에서는 블록 프로그래밍 언어를 선행조직자로 하여 텍스트 프로그래밍 언어를 학습하는 도구 활용 전략을 연구하였다. 텍스트 프로그래밍 언어는 파이썬이며, 블록 프로그래밍 언어는 엔트리, 활용하는 도구는 주피터 노트북으로 선정하였다. 주피터 노트북을 활용한 블록 프로그래밍 언어 선행조직자 학습 전략은 code cell에 IPython.display.IFrame 클래스를 활용하여 결과 창에 엔트리 작업환경을 불러와 선행조직자로 제시하여 엔트리를 학습 후 code cell에서 파이썬으로 학습한다. 주피터 노트북을 통해 블록 프로그래밍 언어를 선행조직자로 제시 후 텍스트 프로그래밍 언어를 제시함으로써 텍스트 프로그래밍 언어를 학습할 때 인지적 부담을 줄어들고 긍정적 전이가 일어나 효과적인 학습이 될 것으로 기대된다.

This study investigates network effects to measure how strongly the early adopters affect the brand choice of the potential consumer. By using the Gumbel-Hougaard (GH) copula, this study checks the magnitude of network effects varied from country to country. To consider consumer heterogeneity and network effects in the growth market, this study proposes the multi-brand Gamma/Shifted-Gompertz (m-G/SG) model based on the GH copula. Out of eighteen Western European cellular phone market data and South Korea smartphone data sets, the m-G/SG model provides an improvement in the estimation accuracy over the Libai, Muller, and Peres model. The results show that network effects enhance (i) the polarization of brand choice probabilities as time elapses; (ii) the dominance of the more preferred and the earlier entered brand; and (iii) the deceleration of category-level diffusion. Potential followers can analyze their relationship with earlier entrants through the m-G/SG model and also establish an optimal market entry strategy.

International Courier Service can be used for on campus pick-up and delivery of small items on a pre-arranged basis or on call. Same day service is available for important items at a minimal fee. As e-commerce develops, effective procurement and delivery become even more critical success factors, offering great opportunities to the transportation and logistics Industry in an e-Commerce World. Much of the logistics industry has developed, or is developing systems to operate in the new e-market to capture new electronic tailer clients and enhance relationships with current customers. Supply chain solutions based on EC links will eventually become standard, leaving some companies behind. fresh opportunities and reduced entry barriers to new competitors via e-commerce pose a major threat to the present logistics industry. supply chain systems developers and industry consultants that subcontract physical transport of goods to contractors may encroach on traditional logistics industry business. In this paper I tried to explain various aspects of the physical distribution service through international courier service in an e-commerce world and survey the logistics strategy of international courier service companies against development of electronic commerce based on our companies, logistics strategy.

The importance of the Chinese fashion market is increasing; therefore, this study investigates the possibility of implementing a Word-of-Mouth (WOM) marketing strategy among Chinese students in Korea. This study examines the effects of consumer characteristics (similarity, opinion leadership, and fashion innovativeness), awareness of Korean fashion brands, satisfaction with Korean fashion products on WOM experiences and WOM behavior (off-line as well as on-line). A total of 161 responses from Chinese students in Korea were gathered and analyzed using SPSS 20.0 for descriptive statistics, factor analysis, and regression analysis. The results show that consumer characteristics (except similarity) significantly influence WOM experiences, opinion leadership influence off-line WOM behavior, and fashion innovativeness influence online WOM behavior. However, similarity has no influence on WOM experiences and WOM behavior. Second, Korean brand awareness affect both WOM experiences and behavior; however, satisfaction with Korean fashion products only affected WOM experiences. This study showed the feasibility of conducting a WOM marketing strategy using the WOM effects of Chinese students in Korea. The study may help the Korean apparel industries establish an entry strategy for the Chinese market.

This study proposes a novel option strategy by using characteristic of volatility reversion and rough set algorithm in options market. Until now, various research has been conducted on stock and future markets, but minimal research has been done in options market. Particularly, research on the option trading strategy using high frequency data is limited. This study consists of two purposes. The first is to enjoy a profit using volatility reversion model when volatility gap is occurred. The second is to pursue a more stable profit by filtering inaccurate entry point through rough set algorithm. Since options market is affected by various elements like underlying assets, volatility and interest rate, the point of this study is to hedge elements except volatility and enjoy the profit following the volatility gap.
