This study is aimed to investigate the effects of foreign exchange rates on stock market returns. For the United States, the United Kingdom, Germany, Japan and Korea, the cross-correlation precedence of foreign exchange rate on stock market is found in the case of Germany and Korea. But that of stock market is not observed in any case. We performed three kinds of causality and exogeneity test of Granger test, Sims test and Geweke-Meese-Dent test. The analyses on the full period show the time-lag causal, exogeneous relation of foreign exchange rates with Granger, Sims and GMD test for Korea. The United Kingdom presents the significance with Granger and Sims test while Germany reveals the time-lag relation with Granger and GMD test. When we divide the period into two parts with the Louvre Accord, the first part give the less degree of time-lag relation. But in the second period the three kinds of causality and exogeneity test propose consistent time-lag relation with foreign exchange rates on stock markets for the United Kingdom and Korea with the three test methods. And Granger's test prove German foreign exchange market have a time-lag relation on stock market.

많은 대학에서 해외 유학생을 유치하기 위해 노력하고 있다. 우리나라의 외국 유학 중에는 지리적으로 가까운 중국학생이 가장 많은 상황이며, 향후에도 지속적으로 증가할 가능성이 있기 때문에 이를 충족시켜 줄 수 있는 다양한 서비스 제공이 필요한 시점이다. 본 연구는 대학 기숙사를 대상으로 하여, 소음요인, 음식요인 및 시설요인이 유학생들의 기숙사 생활만족도에 어떠한 영향을 주는지에 알아보기 위하여, G대학교 중국유학생을 대상으로 실증 연구를 수행하였다. 분석 결과 음식요인과 시설요인은 기숙사 생활 만족도에 유의한(+) 영향을 미치는 것으로 나타났으며, 소음요인은 유의한 영향을 미치지 않은 것으로 나타났다. 연구 결과를 토대로 외국 유학생을 유치하는 대학에서는, 기숙사에 대한 차별화 전략을 사용할 경우 시설 및 음식 요인에 초점을 맞추는 것이 좀 더 효과적이라고 판단된다.

Globalization has led to an increase in foreign banks' penetration. It is argued that the presence of foreign banks may affect the banking sector of the host countries in several ways including their competition level. It is mentioned that the presence of the foreign banks could heightened the level of competition in the banking sector. Nonetheless, the impact of the foreign banks on competition could be influenced by the degree of information sharing in the banking industry. This study investigates the role of information sharing in moderating the impact of foreign bank penetration on host banking sector competition in selected developing countries. We employ panel data samples of 54 developing countries during the period from 1998 to 2016. The estimation is carried out using the two-step system of the Generalized Method of Moments (GMM) regression technique. This technique is adopted due to its robustness to all forms of endogeneity. The findings of this study show that the presence of information sharing could affect the relationship between foreign banks' penetration and competition. They suggest that improvement in information sharing by a host country may help foreign banks to improve monitoring and reduce the moral hazard and adverse selection problem.

The import content of exports (ICE) is defined as the amount of foreign input embodied in one unit of export, and it has been used as a measure of the degree of integration into the global production network. In this paper, we suggest an alternative measure based on the decomposition of gross output and imports into the contributions of final demand terms. This measure considers the manner in which a country manages its domestic production base (gross output) and utilizes the foreign sector (imports) simultaneously and can thus be regarded as a more comprehensive measure than ICE. Korea's input-output tables in 1970-2018 are used in this paper. These tables were rearranged according to the same 26-industry classification so that these measures can be computed with time-series continuity and so that the results can be interpreted clearly. The results obtained in this paper are based on extended time-series data and are expected to be reliable and robust. The suggested indicators were applied to these tables, and, based on the results we conclude that the overall importance of the global economy in Korea's economic strategy has risen and that the degree of Korea's integration into the global production network increased over the entire period. This paper also shows that ICE incorrectly measures the movement of the degree of integration into the global production network in some periods.

The purpose of this study was to furnish data for a new curriculum of the "Bachelor's Degree Course at Junior College" in Korea. Domestic three colleges and one university were selected for comparative analysis about curriculum of the dental laboratory technology. Moreover, three colleges and three universities were selected in Australia, Canada, and USA which are preferred highly on overseas employment by the korea students of dental laboratory technology. From the six colleges and four universities, number of subjects and credit hours on special study were acquired and compared. Between domestics, an agreement on special study were compared. Transferable subjects from korea to foreign were acquired. From the number of subjects and credit hours on special study comparing, following results were obtained. The results were as follows; 1. The ratio of the number of subjects and credit hours on special study were averagely 78.2% and 83.7% in domestic college, 70.8% and 69.7% in domestic university. 2. The ratio of the number of subjects and credit hours on special study in Canada was similar to domestic but those in Australia and USA were less than domestic. 3. Between domestics, an agreement of subjects and credit hours on special study were 81.2% and 84.2% in Catholic University of Busan, 72.2% and 76.4% in Daejeon Health Science College, 71.2% and 72.8% in Gwangju Health College University, 65.1% and 65.9% in Shin Heung College University respectively. 4. Transferable subjects from Korea to Australia or Canada was more than USA. Those to Australia was similar to Canada. These results suggest that the degree of special study in domestic is more than foreign, transferable subjects from Korea to Canada should be profitable and those data is furnish for a new curriculum of the "Bachelor's Degree Course at Junior College" in Korea.

A foreign body in the airway can be a potentially life-threatening event. The diagnosis and treatment of foreign bodies in the airway are a challenge for otolaryngologists. Despite the improvements in medical care and public awareness, approximately 3,000 deaths occur each year from foreign body aspiration. A high degree of vigilance is required to ensure prompt treatment and avoid the complications of foreign body aspiration. The author encountered a case of a 77-year-old female patient who had aspirated an unknown foreign body that was fixed in her main bronchus. An initial attempt was made to remove it with a flexible bronchoscope but failed due to the patient's hypoxemic state during the procedure. Under general anesthesia, a rigid bronchoscopic examination was performed, but it was difficult to approach the object due to the bronchus curvature. Instead, a cryotherapy instrument of bronchoscopy was applied. The foreign body was frozen and removed to the carina, where a laryngoscope and laryngeal forceps were used to remove it.

본 연구는 한류 지속가능성에 한류 드라마 '시청정도'가 미치는 직접효과와 '한류호감도' 및 '문화유입수용성'의 매개효과 그리고 '경쟁의식'의 조절효과를 실증적으로 규명하였다. 표본은 중국 광서성의 계림시와 하남성의 정주시에 거주하는 대학생(N=371명)이다. 분석 결과, 한국에 대한 '경쟁의식'이 상대적으로 약한 응답자들의 경우에는, '한류 지속가능성'에 유의한 영향을 미치지는 않았지만, 경쟁의식이 상대적으로 강한 응답자들은 한국 드라마 '시청정도'가 증가할수록, 오히려 한류 지속가능성에 대해서 회의적인 입장을 표명하여 주목하게 되었고, '경쟁의식'의 조절효과가 입증되었다. 한류 드라마를 많이 시청할수록, '한류 호감도'도 증가시키지만, '문화유입 수용성'에는 유의한 영향을 미치지 않았다. '시청정도'가 증가할수록, '한류지속 가능성'에 대한 부정적인 평가를 하는 경향은 '한류 호감도'가 증가할수록 유의하게 감소될 수 있어, '한류 호감도'의 매개효과가 입증되었다. 주요 발견점을 토대로 시사점과 함의를 논의하였다.

The purpose of this study is to discuss how to introduce micro degree for innovation in convergence education in our university. To this end, the background of the introduction of micro and nano degrees and domestic and foreign applications were reviewed. The reason why the rate of students completing the multi-degree was low was that the credits required for graduation were higher than that of other domestic universities, and the difficulty of the courses offered in the convergence major did not match the students. In order to reduce the burden of students learning convergence subjects while acquiring new knowledge and skills, the introduction of a micro degree is considered to be an alternative to the current convergence education.

We present a unified explanation of the internationalization strategies of major mobile network operators (MNOs). We have developed a framework that analyzes the strategies of major international MNOs in terms of the relationship between their degree of involvement in international business operations and the degree of equity participation. The results show a positive association between these two dimensions as expected, but they also reveal some exceptional cases in which certain MNOs are actively involved in the business operations of other foreign MNOs, even with minor (or zero) equity investments. In this paper, we argue that the strategic actions of the major MNOs which are the largest shareholders of foreign MNOs are in an equilibrium status because these major MNOs derive maximum benefit from full or considerable management control and active involvement. Finally, we predict that latecomers (MNOs who are just about to enter foreign telecommunications markets) may adopt an incremental investment approach because most developed markets and deregulated emerging markets with growth potential are already preempted by major MNOs. Therefore, the window of opportunity for internationalization in those markets is currently small.

The aim of this study is to estimate the impact of ownership structure on the performance of listed firms in transition economy. Buiding upon agency theory, hypotheses on such relationship are proposed. A detailed panel data of 502 non-financial companies listed on Ho Chi Minh Stock Exchange and Hanoi Stock Exchange over the period from 2013 to 2018, and the system generalized method of moment estimation are employed to test the proposed hypotheses. To ensure the reliability of data, this study excludes companies that violate information disclosure regulations or that are subject to special supervision by the State Securities Commission of Vietnam. Some firms with inadequate information, firms that lack the financial data required for creating variable or firms that have inconsistent construction are also re-screened. We only collect the data of enterprises that have ownership structure of two or more components. Estimation results reveal that state ownership has an U-shaped relationship with the performance of Vietnamese listed firms, while foreign ownership and the degree of ownership concentration have an inverted U-shaped relationship with listed firms' performance. The article provides governance implications that Vietnamese listed firms should decrease state ownership and foreign ownership to improve firm performance in order to boost investors' confidence.
