Purpose - The purpose of this paper is to seek some alternative to overcome difficult shipping situations for overcapacity pursuing economy of scale, which is widely spread in world shipping. Research design, data, and methodology - The research method to be adopted is first to review evolution of larger ships in terms of theoretical overview, and shipping market is examined, and it is studied some problems and solutions in relation to larger ship as field research aspects. Results - Supply and demand of shipping market is flexible and unpredictable nature of market. Sometime fierce competition has spread out the market, and shipowner may deploy mega ship in terms of economy of scale, etc., to overcome the difficult market situations. Both carrier and shipper have their own positions in this matter concerned. However, it causes some problems in the market including port matters, etc. Therefore, it is asked to solve this problems of larger ship employed in the markets, throughout shipping alliances, etc. Conclusions - Over tonnage done by larger ship has caused some problems in the shipping markets, forming monopolistic market by small number of larger shipping companies, destroying oligopolistic nature of shipping business, therefore, the answer is strategic alliance to collaborate each other.

Distribution of fish products from Tongyoung Marine ranching can be classified by three routes such as street-stall, live fish transportation vehicles, and wholesale markets neighboring unloading ports. These methods of distribution, however, have been restricted by limited distribution right, difficulties to differentiate fish prices from other surfaces, simple marketing channels. The ratio of cultured live fish circulated in market is increasing while naturally caught live fish is decreasing and the fresh fish shows a little of increasing rate. Consumers purchasing routes mainly depend on the live fish transportation merchants. For fresh fish traditional market plays an important role in trade. Convenience for consumers and quality of products are main factors in making decision of purchases. Bargaining power, however, belongs to the live fish transportation merchants. The demand of special markets for live fish was very strong, and the convenience and quality are relatively important required factors. Catch from Tongyoung Marine ranching has very good reputation as the possibility of being a good brand. Expecting possibility of quality differentiation was higher than price differentiation specially. The possible conclusion of a contract of a supply was suspicious however. Preliminary quality evaluation revealed that the catch is better than the cultured but worse than naturally grown fish. A merchandising is to be in a better position in the formation of prices by giving $\ulcorner$brand image$\lrcorner$ to potential consumers. The target markets are retail stores such as restaurants for raw fish and final consumers. The staple markets are retail stores. Possible items of products are live fish, fresh fish for cook, and fresh fish for raw fish. It is necessary for the catch to be informed as new functional products that have been improved in safety and quality, since the product positioning is similar but not well known to consumers. To secure a brand it is required to register a trademark, eco-label product design or packing, use real name in tranction, introduce recall system, and put label. Price higher than naturally grown live fish should be targeted. Establishing broad distribution channel, wholesale market, franchise are required. To secure enough catch and control shipment of products facilities of containing live fish are necessary. Instead of dealing with live fish only, it would be better to. sell fresh fish and live fish simultaneous. Strategically promotion focuses on advertisement of Marin ranching at first and then focuses on the catch from the marine ranching.

Purpose - The aim of this study is to develop an empirical model of the effects of traditional market service quality factors on customer value, relationship quality, and behavior. The specific objectives of the study are as follows: 1) to classify study objects into cultural tourism markets and non-cultural tourism markets as well as to verify the differences in service quality among the two markets and, 2) to present practical service marketing methods that fit with the characteristics of the traditional markets by amending the five quality evaluation items of SERVQUAL (a multiple-item scale for measuring service quality)to suit the characteristics of the traditional markets and establish the relationship among customer value, relationship quality, and behavior intention. Research design, data, and methodology - The study methods of empirical investigation are as follows. First, this study selected for a study object the Suwon Paldalmun Gate Market to represent the cultural tourism market, and general traditional markets to represent the non-cultural tourism market. This study also conducted personal interviews in order to increase the response rate and collected a total of 418 responses between March 18, 2014 and April 05, 2014. The total of 418 responses used for this study excluded 14 responses that had either misleading information or missing values. Results - This study verified the perceived differences of service quality based on traditional market specialization through an independent sample t-test. It appeared that the perceived service quality of the cultural tourism market was generally higher than that of the non-cultural tourism market. This study executed a path analysis in order to examine the effects of service quality factors on customer value, relationship quality, and behavior intention. This study also comprehensively analyzed the specialized market and non-specialized market separately. Although there were some differences among the results, the overall results were uniform. It appeared that convenience, reliability, and empathy, among the service quality factors, exerted meaningful effects on customer value. On the other hand, convenience, reliability, responsiveness, and empathy, excluding the tangibles, exerted meaningful effects on the relationship quality. In addition, it appeared that all service quality factors exerted meaningful effects on the customer value, relationship quality, and behavior intention. Therefore, the study verified that all of the hypotheses formulated in the study were generally adopted. Conclusions - The implication of this study may be classified into academic and practical implication as follows. With respect to the academic implication, it seems that this study is among the early studies to verify the differences between the cultural tourism market and the non-cultural tourism market. The practical implication of this study is that the perceived service quality, such as convenience, reliability, responsiveness, and tangibles, excluding empathy, was higher in the cultural tourism market than in the non-cultural tourism market. This means that customer satisfaction is enhanced by governmental aid such as hardware, software, and information and communications technology.

Purpose - This paper investigates how the market value of the firms are impacted by distribution information technology investment in Korea over time and across markets, industries and project characteristics. This is the first empirical study on the market payoffs from the RFID investment in Korea. The purpose of this study is to provide a appropriate guideline for investors and practitioners with respect to the announcement representing RFID adoption in Korea. This reaction guideline will stimulate the practitioners to monitor and evaluate the benefits and costs of the innovative RFID technology. Research design, data, and methodology - This paper employs event study methodology to analyze the payoffs from distribution information technology investment announcements over a fifteen-year period from 2003 to 2017. Event study method is based on the assumptions such as market efficiency, unanticipated RFID invest announcements and no confounding effects in the data. This study collected the information on RFID investment announcements by using a full text search engine Bigkinds provided by Korea Press Foundation over a fifteen-year period from January 2003 through December 2017. This paper selected 88 announcements representing RFID adoption by 46 firms. This paper estimated the payoffs from RFID investment announcement through events windows by using the market model of Mcwilliams and Siegel (1997) and calculated the Z-values. Using this test statistics we could infer if RFID adoption make large differences in abnormal returns across various classifications of the firms. Results - There is significant positive market returns from the announcement representing distribution information technology investment in the pre-2009 time period, the significances of payoffs disappear in the post-2009 time period. For this reason investors or practitioners can understand the importance of market entry time and the fact that the greater rewards may belong to early innovators while late imitators cannot reap such a rewards. This paper also find that there is a large differences in the payoffs from the announcement across markets, industries and project characteristics. Conclusions - Analysing the selected sample of 88 announcements representing RFID Adoption over fifteen-year period from 2003 to 2017, this study find that there is not only significant abnormal excess returns from RFID investment announcements but also there is great differences in the abnormal returns over time and across firm sizes or affiliated markets, industries, and project characteristics. This means that there are considerable values for the investors across various firm classifications. The findings of this paper provide useful implications for the practitioners to make judicious decisions whether to adopt the innovative technologies in general or not considering the various concrete circumstances in Korea.

자본시장의 국제화를 맞이하여 국내 투자자 및 자본시장의 보호를 한층 강화할 필요가 있는 상황에서 우리 자본시장법은 동 법의 역외적용여부를 명문화하고 있다. 그 결과 특정 국외행위의 효과가 국내에 미치는경우에는 자본시장법의 관련 규정에 따라 해당 행위를 다국적 차원에서규제할 수 있다. 효율적 규제를 통한 자본시장법의 입법목적 달성은 관련법령의 집행과 불가분의 관계에 있는데, 다양한 집행 수단 가운데 공적기관에 의한 법규위반 행위의 적극적인 적발 및 제재가 현실적인 규제의첫 단계가 된다. 그렇지만 순수한 국내 거래와는 달리 국제적 거래의 규제 시에는 법령집행의 불확실성을 가중시키는 다양한 차원의 문제들이대두된다. 이 글에서는 국내 공적기관이 국제적 불공정거래행위를 규제하고자 할 때 적용되는 관련 법제의 현황을 살펴보고 몇 가지 관련 제안을하였다. 첫째, 자본시장법을 비롯한 금융실명법은 국내 감독기관인 금융위원회가 위법한 국제적 증권거래를 규제하기 위해 조사 및 증거 수집을 하는단계에서 외국의 감독기관과 협력할 수 있는 법적 근거를 마련하고 있다. 이에 근거하여 금융위원회는 외국의 감독기관과 개별적으로 MOU를 체결하거나 IOSCO의 MMOU에 가입하여 효과적인 상호협력과 정보교환을하고 있다. 금융위원회는 향후 IOSCO를 통해 지속적인 국가간 협력을 도모함으로써 집행의 효율성을 담보할 것이 요구된다. 둘째, 국제적 불공정행위에 대한 효과적인 형사제재를 위해서 국제형사사법공조 역시 필수적이다. 국내에서는 국제형사사법 공조법이 제정되었고, 다양한 국가와 형사사법공조 범죄인인도 수형자이송 등에 관한 조약을 체결하고 관련 협약에도 가입하였다. 국제적인 불공정거래의 규제와 관련하여 국제형사사법공조시 적용되는 원칙 가운데 쌍방가벌성의 요건은 완화하여 적용할 필요가 있다. 나날이 거래기법이 교묘해지는 새로운유형의 불공정행위 같은 경우에는 동일 수법이 광범위하게 활용될 수 있으므로 특정 국가의 법령상 범죄를 구성하지 않더라도 예방적 차원의 규제를 위한 공조가 요구되는 까닭이다. 셋째, 불공정거래행위의 근절을 위해서는 보다 근원적인 방안으로서 불공정거래를 통해 취득한 경제적 이익을 박탈하는 범죄수익환수를 고려하여야 한다. 현행 범죄수익규제법은 외국규제기관이 한국의 관할 내에 있는 불공정거래자의 범죄수익을 환수하고자 할 때 적용되는 국제공조에관한 규정을 두고 있다. 위법한 국제적 불공정거래로 인해 피해를 입은투자자들이 차후에 실질적으로 손해를 배상받도록 하기 위한 방안의 하나로서, 외국사법기관이 집행한 범죄수익을 국내로 환수하여 불공정거래의 피해자들에게 환부하는 제도를 마련할 필요가 있다.

In this paper, we introduce the optimal approximation by a Gaussian function for a probability density function. We show that the approximation can be obtained by solving a non-linear system of parameters of Gaussian function. Then, to understand the non-normality of the empirical distributions observed in financial markets, we consider the nearly Gaussian function that consists of an optimally approximated Gaussian function and a small periodically oscillating density function. We show that, depending on the parameters of the oscillation, the nearly Gaussian functions can have fairly thick heavy tails.

본 연구에서는 벡터오차수정모형(VECM)을 이용하여 유통단계별 감귤시장의 가격전이 메커니즘을 이해하고 가격 결정력을 지니는 유통단계를 확인하고자 하였다. 일반적으로 농 축 수산물의 유통과정은 도매시장에서 소매시장으로 가는 2단계 유통과정을 거친다. 그러나 경우에 따라서는 산지 도매시장에서 소비지 도매시장을 거쳐 소비지 소매시장으로 가는 3단계 유통과정을 거치는 경우도 있다. 이렇게 각 시장에서 형성되는 농 축 수산물의 가격은 유통마진의 격차를 두고 서로 밀접한 연관을 지니며 움직이는 것이 특징이다. 그러나 각 시장의 가격결정 과정에서 농어업인, 도소매 유통인 및 가공업자 등의 시장지배력, 소비자 또는 정부의 영향력에 따라 각 시장의 가격생성 메커니즘이 영향을 받을 것이고, 이에 따라 각 시장의 인과행태가 발생할 것이다. 제주감귤 역시 생산자 단체와 산지 유통인을 통하여 도매시장이나 대량 수요처 등으로 운송되며 도 소매시장 및 대형유통업체를 통하여 최종 소비자에게 유통되고 있어 전반적으로 도매시장에서 소매시장으로 가는 2단계 유통과정을 거치고 있다고 볼 수 있다. 본 연구의 주요 결과는 다음과 같이 요약할 수 있다. 첫째, 감귤의 도매가격과 소매가격 간의 유통단계별 수준변수 시계열에서 장기균형관계가 성립하였다. 둘째, 감귤 가격의 도매시장과 소매시장 간의 인과방향은 단기적인 측면에서 도매시장에서 소매시장으로의 일방적인 인과방향을 확인할 수 있었다. 셋째, 장기적인 측면에서 감귤 가격의 도매시장과 소매시장 간에는 서로 쌍방향적인 피드백 효과가 있는 것으로 분석되었다. 이러한 결과는 감귤 유통시장에서 도매가격이 가격형성에 가장 중심적인 역할을 하며, 감귤의 가격결정에 있어 도매시장의 영향력이 매우 크게 나타나고 있음을 의미한다고 하겠다. 결국 경쟁력 있는 감귤산업의 발전을 위해서는 산지 조직화를 통한 감귤생산의 수급조절 정책의 적극적인 추진이 필요한 것으로 사료된다.
