  • This study investigated the relationship between business-to-business service quality and loyalty by applying the IMP (International/Industrial Marketing and Purchasing Group) model. The study found that six dimensions of service quality which were product exchange, financial exchange, information exchange, social exchange, cooperation, and adaptation explained B2B service quality very well. More specifically, the study found that service quality dimensions of social exchange, cooperation, and adaptation were more important than those of product exchange, financial exchange, and information exchange. The study also found a positive relationship between service quality and loyalty. In fact, organizational buyers appeared to show greater loyalty as they perceived service quality better.

  • International contractors must consider the substantial risks related to unexpected foreign exchange fluctuation incurred by conducting their business and using foreign currencies in foreign countries. Most international contractors attempt to minimize foreign exchange exposure within a manageable range because it may influence the company's fundamental financial structure, reduce market value or profit margins, or disrupt ongoing and future projects. This research provides a qualitative study of existing foreign exchange exposure (transaction, operation, and translation exposure) and current & effective foreign exchange risk management in American and Korean international contractors, as they represent both new and long-time members of the global construction market. Finally, recommendations of techniques for new and existing international contractors to minimize and better manage foreign exchange risk will be offered.

  • International exchange implementing the Internet began inevitably due to the pandemic, but it provided Digital Nomads with new experiences in their lives using the Internet. This study the possibility and challenge of international exchange implementing the Internet identified. To this end, we explored its strengths and weaknesses through interviews and descriptions of students who participated in international exchange. As a result, we identified that students were positive in the diverse aspects of communication tools and ways, whereas they were negative because they felt difficulties in the physical environment, inaccessible physical conditions especially. They were also negative in the emotional exchange, an ice-breaking which needed much more time than offline exchange. Therefore, we identified in the case of designing or conducting student activities implementing the Internet, including international exchange, the possibility of activities implementing the Internet could be much more extended if their developer various programs considered in the introduction step.

  • 본 연구에서는 형질전환된 식물세포배양으로 생산한 (hGM-CSF)를 cationic exchange resin인 CM-sepharose와 anionic exchange resin인 DEAE-sepharose에 통과키며 pH의 변화를 주었을 때 흡착 여부를 확인하였다. hGM-CSF는 pH가 5-7사이의 범위에서 가장 안정함을 보였으며 이 결과를 바탕으로 각각의 pH 범위를 결정하였다. Buffer exchange를 했을 때 cationic exchange resin인 CM-sepharose의 경우 pH 4.8에서 상대적으로 가장 높은 흡착율(77%)을 보였으며 anionic exchange resin인 DEAE-sepharose를 이용한 흡착에서는 pH 5.5에서 높은 흡착율(74%)을 보였다. 이러한 결과를 바탕으로 buffer exchange 없이 hGM-CSF가 secretion된 배지를 pH를 맞춘 후 좁은 범위에서의 흡착 실험을 수행하였다. 그 결과 pH 4.6에서 CM-sepharose를 이용했을 때 흡착율이 84%로 가장 좋았다. 이러한 결과를 이용하면 외래 단백질을 생산하는 식물세포 배양시에 가장 문제가 되는 protease에 의한 목적 단백질의 degradation을 해결할 수 있는 in situ adsorption이 가능하리라 사료된다.

  • 본 논문에서는 단단계(Single-Stage) Shuffle-Exchange 네트워크의 분할성에 대하여 연구하였다. SSEN_to_PSEN 알고리즘은 단단계 Shuffle-Exchange 네트워크를 분할 가능한 Shuffle-Exchange 네트워크로 변환하는 방법을 제안한다. 제안된 알고리즘은 네트워크의 크기가 N $\leq$ 8일 경우에는 추가적인 링크없이 네트워크가 분할성을 갖는 것을 보이며, 네트워크의 크기가 N $\geq$ 16일 경우에 단단계 Shuffle-Exchange 네트워크를 분할하기 위해서는 추가적인 링크가 필요하다. SSEN_to_PSEN 알고리즘의 시간 복잡도는 $\theta$(NlogN)이며, 하이퍼큐브 네트워크와 비교하여 분할 가능한 Shuffle-Exchange 네트워크는 적은 링크 수를 사용한다. 분할이 가능해짐에 따라서 대용량의 병렬컴퓨터에서 분할 가능한 Shuffle-Exchange 네트워크는 여러 사용자들을 위한 다양한 문제의 처리가 동시에 가능하기 때문에 컴퓨터의 처리 효율이 향상됨을 알 수 있다.

  • The research for exchange relationship in customer's perspective is meaningful especially in service, considering distinctive characteristics of service operations such as customer participation in the process whereas most of the recent related researches have been focused on employee's interaction with organization, leader, team and customer. In this study for beauty art service, the exchange party's characteristic is defined with beauty salon's reputation, staff's professionalism and customer's self-esteem. Also the exchange relation perception is classified into symbolism and interaction, Then the directional relations on customer's perspective are empirically investigated in the sequential order of the exchange party's characteristics, the exchange relation perception, the relationship quality and behavioral intention. In addition, the study examined the meditation effect via relationship quality between the exchange relation perception and the behavioral intention. Followings are confirmed from the statistical test with structural equation modelling:Symbolism is significantly caused by all of professionalism, reputation and self-esteem in the descending order of effect size whereas interaction is significantly influenced by only professionalism. The exchange relation perception has significant effect on the relationship quality, in turn which significantly affects behavioral intention. The exchange relation perception shows the significant indirect effect meditated by relationship quality and the insignificant direct effect on behavioral intention. This paper concludes with contribution of this study, managerial implication of the research findings and further research issues.

  • International capital movement has made progress at global liberalization of finance and foreign exchange, international monetary norm changing into floating exchange rate system, easiness of collection of information and trade at improvement of information communication technology from early of 1970's. Results of empirical test for relation between foreign exchange rate or various determination factors of foreign exchange rate and interest rate are followed by next sentences. First, according to relation between foreign exchange rate and interest rate, correlation for each of variables after OECD entrance is increased. But, long-term & short-term interest rate is affected by Hanbo & Kia's bankruptcy, continuous large scale corporates bankruptcy and crisis of foreign exchange. Therefore, financial instability is occured. If portfolio investment fund has been inflow as it is mollified by continuous shortage of foreign exchange and fall of country's credit rating, it is expected to have positive effect for long-term & short-term interest rate from appreciation of won against dollar. Second, results from relation between determination factor of foreign exchange rate and interest rate are followed by next sentences. If surplus of current account and goods account is continued, yield of corporate bond is to be stable. But, margin of surplus is expected to diminish after second quarter 98, and difference between external and domestic interest (after adjusting foreign exchange rate) is to be diminished. And if net inflows of foreign investor's fund (stock and bond) is diminished, it is to have negative effect for yield of corporate bond. According to foreign investor's investment movement of previous years, hedge fund were stayed at least during two years in Mexico. It means that sudden capital outflow is not to be happened at Korea. But if external factors from depreciation of yen and China's renminbi are instable, interest rate is expected to increase from capital's outflows. Third, if it is to decrease instability of foreign exchange rate from increase in surplus of future current account, credit rating's upwardness, stability of yen and renminbi, foreign exchange rate is expected to be stable. It is expected to have continuous stability from short-term interest rate to long-term interest rate in this empirical test.

  • The exchange rate volatility has been increased since the time when the floating exchange rate system was introduced in Korea. As a result, the increase of the exchange rate volatility raised the risk in international trades in Korea. The purpose of this study in to study the feature of exchange rate volatility and the main sources of its increase and to confirm whether the exchange rate volatility influence export volume and price of Korea. In the first place, I measured exchange rate volatility with two methods. The one is descriptive statistic method such as the width of daily exchange rate fluctuation and the rate of exchange rate devaluation. The other is the time varying conditional variance of exchange rate. Then, I studied the sources of exchange rate volatility. In the second place, I defined the exchange rate volatility as the time varying conditional variance and estimated it by using elastic a approach model which shows exchange rate is affected by itself and its conditional variance, I estimated its effects on export volumes and prices of electric home appliances, information & communication equal and semi-conductor. The result of this study is as follows. With presumed result EU and Korea because is not the goods which is to substantial competition relationship, The effect where the relative value change of presumed result expression anger and the dollar of import and export function goes mad to the import and export of Korea the income compared to is to export and it is appearing a lot. The EU goods is sold more expensively the Korean goods than from about length being caused by American market of the dollar and the balance of trade of Korea is visible like being visible the improvement of single breadth. Because the relationship of competition is weak but substantially there is to a short term and expression - the effect where the dollar rate fluctuation is big in Korean trade there is a possibility of saying that widely known it is not.
