If T is an unbounded hyponormal operator on an infinite dimensional complex Hilbert space H with ${\rho}(T){\neq}{\phi}$, then it is shown that T satisfies Weyl's theorem, generalized Weyl's theorem, Browder's theorem and generalized Browder's theorem. The equivalence of generalized Weyl's theorem with generalized Browder's theorem, property (gw) with property (gb) and property (w) with property (b) have also been established. It is also shown that a-Browder's theorem holds for T as well as its adjoint $T^*$.

본 연구에서는 글로벌 경쟁시대의 기업성과향상을 위하여 수출기업에서 자기주도학습능력이 직무만족과 조직몰입에 미치는 영향을 살펴보고, 집권화와 분권화된 조직문화특성이 자기주도학습능력과 직무만족과 조직몰입에 미치는 조절효과를 살펴보았다. 연구결과는 다음과 같다. 첫째, 학습에 대한 자기주도학습능력 변수 중 학습의 책임수용성 변인만이 직무만족과 조직몰입에 정적(+)인 영향을 미치는 것으로 나타났다. 둘째, 집권화의 조직문화의 조절효과를 살펴본 결과, 학습의 책임성 수용(t=-1.934, p<0.01), 학습자적 신념(t=-1.820, p<0.001), 미래지향성(t=2.249, p<0.001) 변인들과 조직몰입 관계에 집권화가 조절효과를 나타내고 있는 것으로 나타났다. 셋째, 미래지향성(t=-1.645, p<0.01) 변인과 조직몰입 관계에 분권화가 조절효과를 나타내고 있는 것으로 나타났다. 본 연구결과를 통하여 학습자 개인적차원과 조직적 차원에서 자기주도학습능력에 대한 지원 및 분위기 조성이 전제 되어야 한다는 기존 연구결과를 수출기업에서 다시 재확인하였으며, 지식정보사회에서 조직의 역량과 성과를 향상시키기 위해 관료제적 계층조직에서 유기적 학습조직으로 적극 변화되어야 한다는 연구결과를 제시하였다.

The question of what our cultural goods might have known in a major exporting market, has intrigued investigators since 2000 year. Actually, Maybe Korean cultural assets just didn't have time to get to know International or Asia market. But now, a new euphoria can be tasted, on the lips of the small but growing Korean Contents Mania, as New Korean Wave-Crust begin to welcome the priciest contents from korea. Given Asian's surging population for our entertainment contents-drama, movie, music, character, etc., and the sense of a positive response its newly international market, it is hardly surprising. Now, Korea Wave must play an important roles in our country- economy, business, specially. This paper is seeking in OSMU on Korean Contents in East-North Asian Market, and is developing about Korean Wave study model. and It also points to a different strategy for exporting cultural contents, suggesting it should be effected for model to OSMU.

Since 1970s, there are many tries to realize electronic bills of lading(e-B/L) in the world and great attention has been shown to the question of law, international trade customs and realizing strategy concerned that instrument. However that tries, include Bolero which is most famous company serving e-B/L, don't succeed yet. Meanwhile, Korean government amended commercial code in order to realize e-B/L on August 3, 2007. Also The Korea Paperless Trade Center set to develop the e-B/L system by spring of 2008. So far, however, no definitive answer has been given to the way of realization of e-B/L in Korea. Getting bigger the importance of analysis to the ways of realization of e-B/L in Korea, in this paper the author attempt to examine the requirements after briefly outlining and analysing the results and problems of the tries and suggest thereby policy and strategy about the realization classified three categories.

Korea has been faced a difficult situation with regard to the cost of physical distribution(PD). The problem have arisen from the fact that Korean firms have far different cost structures of the PD according to its industry or business. High PD costs sometimes reduce firms' operating income and perceived competitive disadvantages not only in domestic but in world-wide business. In this research, we examine the factors affecting firm's PD cost by investigating financial and non-financial variables such as variable cost to sales ratio and number of employee of a firm. Analyses are performed to construct research models with t-test and the logistic regression estimation.

The purpose of this study is to examine the causal relationship between the exchange rate and economic growth, and to induce policy implications. In order to test whether time series data is stationary and the model is fitness or not, we put in operation unit root test, cointegration test. And we apply Granger causality based on an error correction model. The results indicate that uni-dierctional causality between exchange rate and economic growth is detected. Exchange rate impacts on economic growth, but economic growth don't impact on exchange rate. The analysis of impulse reaction function shows that the impulse of exchange rate impacts on Korean economic growth in negative direction. We can infer policy suggestion as follows: The fluctuation of exchange rate much affects economic growth, thus we must make a stable policy of exchange rate to continue economic growth.

This study shows the following results. First, the assessment items of the whole exhibition operation, workforce, counselor's ability, facility and environment were important analysis factors for exhibition recognition, quality of human operation and quality of exhibition facility and environment. Second, exhibition recognition was found to be the most significant factor that influenced exhibitor's cognitive achievement, exhibition employee operation and exhibition facility. Third, exhibitors' satisfaction simultaneously increased as exhibition recognition and employee operation quality were raised. However, exhibition facility didn't strongly influence exhibitors' satisfaction. Fourth, high exhibition recognition, employee operation and exhibition facility resulted in high cognitive achievement and exhibitor's loyalty. Fifth, exhibition recognition is a highly influential factor to mediate exhibitor's cognitive achievement and exhibitors' loyalty. It implied that exhibitors' cognitive achievement and satisfaction were significantly related to the exhibition quality factor. Moreover, it indicated the effective and efficient operational method to strengthen promotional strategy, enhance the quality of employee operation, exhibition facility and environment. Thus, the results suggest a new method to evaluate exhibitor's satisfaction in the exhibition industry.

The purpose of this study is to explore the antecedent factors to the piracy of the digital copyrights in order to provide basic data for piracy prevention policy. The findings of study revealed that most respondents had experiences to copy MP3 files illegally. And many respondents answered they didn't copy pirated material by themselves but others did piracy a lot. The feeling of quilt and anxiety against piracy is shown very low level. Low copy cost and regulation level significantly impact upon the cognitive level of other's piracy. Updated contents, the higher price of authenticated materal, piracy regulation are the significant antecedent factors to the level of piracy. The level of piracy activity and anxiety against piracy are significantly different by age. The cognitive level of other's piracy, piracy activity and anxiety are significantly different by gender.

Dispute plays a key role in maintaining the desirable performance of trade transaction. In an effort to stay competitive in a global marketplace, the Korean companies need to become more aware of alternatives to costly and time-consuming litigation. Korean companies, therefore, should be more concerned with ADR(Alternative Dispute Resolution) system and should utilize ADR to settle their disputes effectively and efficiently. ADR encompasses all process of dispute resolution as a substitute for the traditional litigation. Generally, three kinds of ADR are available in Korea: Negotiation, mediation, and arbitration. This article investigates reasons why ADR isn't used well in Korea and suggests ways how ADR can work best in international trade disputes. To expand ADR system in international trade disputes, it is very important for both the company and the scholar to recognize the concept and usefulness of ADR system. The Korean Commercial Arbitration Board also must help both Korean companies and scholars recognize the mechanism of dispute resolution and utilize ADR system in international trade disputes.

A digital cable broadcasting service is a multimedia broadcasting service that provides high definition and various supplementary services by using digital transmission. Korea implemented a complete digital broadcasting service by 2012. This study applied a choice experiment to investigate consumer preferences, and it calculated the marginal willingness to pay for this service. Moreover, we employed a multinomial probit model to relax the assumption that all respondents have the same preference for attributes being valued. The results suggest that respondents value channels, definition, video-on-demand (VOD) service, pay-per-view (PPV) service, and commerce based on TV (T-commerce). On the other hand, online gaming may be less important as an attribute for digital cable broadcasting service in Korea.
