The United States is Korea's important trading partner, ranking third (13.7%) in exports of fishery products in Korea. The impact on exports to the United States is expected to be significant if the seafood import provisions under the MMPA are implemented in 2024 accordingly. It is expected that documents proving production information will be required for all items when exporting to the U.S. Therefore, this study attempted to examine the current status of exports and exporters in order to understand the actual conditions of major fishery products exported to the United States. Besides, there are currently no official system and procedures in Korea to prove production information for all fishery items, so we tried to suggest implications by examining distribution channels for major export items to the U.S. In this study, five items including seaweed and halibut as domestic aquaculture items, tuna and squid as deep-sea fishing items, and fish cake using imported raw materials were selected as the target items for distribution channel investigation. In addition, this study is meaningful in that it investigated the routes from production to processing, distribution, and export of each item and identified detailed distribution channel for major items exported to the U.S.

U. S. commercial landings of wild salmon have remained relatively stable for the past 5 years, averaging 300,000 MT. While the same period, U. S. imports of fresh salmon have increased over ten fold from 1.8 to over 19 million pounds. Over 70 percent of the new supplies of fresh salmon come from Norway. Norway exports to the United States were negligible in 1980 and 1981. However, U. S. imported 1,768 M. T. in 1983, 3,896 M. T. in 1984, and 6,272 M. T. in 1985. Over the past 5 years, import price of fresh wild salmon from Canada has declined steadily from ＄2.58 per pound to ＄1.25 per pound in 1985, while those from Norway had remained unchanged, ranging from ＄3.28 to ＄3.45 over the same period. Norway's cultured salmon entered the United States in 1985 at about ＄3.35/1b., roughly triple the price of Canadian fresh wild salmon imports. U. S. apparent consumption of fresh and frozen salmon has sharply increased from 50,000 MT in 1981 to 92,000 MT in 1985, up 86 percent over the five years. Annual per capita consumption has increased steadily from 0.47 pounds in 1981 to 0.85 pounds in 1985. The estimated demand models show that the annual wholesale price of fresh salmon in the U. S. market would be declined by increase in supplies and would be raised by increase in the U. S. GNP. The empirical results in this study show that wholesale price of fresh salmon in 1990 would remain unchanged at the 1985 level, under the following condition: 1) Norwegian production of Atlantic fresh salmon would reach 80,000 MT (176 million pounds by 1990) 2) Imports of Norwegian Atlantic fresh salmon would keep the same percentage (21%) of Norwegian productions in 1990 3) Imports from other countries and U. S. domestic production would increase and maintain the same level of 25% of U. S. total supplies in 1990 4) U. S. GNP would increase by ＄200 billion annually, slightly less than in the past years.

The aim of this paper is to study the class of ${\Lambda}$-constacyclic codes of length $2p^s$ over the finite commutative chain ring ${\mathcal{R}}_a=\frac{{\mathbb{F}_{p^m}}[u]}{{\langle}u^a{\rangle}}={\mathbb{F}}_{p^m}+u{\mathbb{F}}_{p^m}+{\cdots}+u^{a-1}{\mathbb{F}}_{p^m}$, for all units ${\Lambda}$ of ${\mathcal{R}}_a$ that have the form ${\Lambda}={\Lambda}_0+u{\Lambda}_1+{\cdots}+u^{a-1}{\Lambda}_{a-1}$, where ${\Lambda}_0,{\Lambda}_1,{\cdots},{\Lambda}_{a-1}{\in}{\mathbb{F}}_{p^m}$, ${\Lambda}_0{\neq}0$, ${\Lambda}_1{\neq}0$. The algebraic structure of all ${\Lambda}$-constacyclic codes of length $2p^s$ over ${\mathcal{R}}_a$ and their duals are established. As an application, this structure is used to determine the Rosenbloom-Tsfasman (RT) distance and weight distributions of all such codes. Among such constacyclic codes, the unique MDS code with respect to the RT distance is obtained.

This study examines whether the adoption of International Financial Reporting Standards (IFRS) has increased financial statement comparability among firms and reduced undervaluation of Korean firms in the capital market by enhancing financial statement comparability. The so-called Korea Discount, which indicates an inefficient allocation of capital, has been attributed to lack of transparency and comparability of accounting information. Therefore, an efficient distribution of capital in the market was intended when IFRS was first adopted in Korea, but such progress is based on a premise of enhancement in Korean firms' accounting information comparability. This study conducts empirical analysis by using a comparability measure by De Franco et al. (2011). More specifically, it analyzes differences among comparability of domestic firms following IFRS adoption, with firms in the EU, which adopted IFRS in 2005, and with firms in the U.S., China and Japan that do not follow IFRS. The analysis of changes in domestic firms' comparability finds that their comparability improved following IFRS adoption. Meanwhile, the examination of cross-national differences in comparability demonstrates that, although there has been no significant change in comparability with firms in the U.S. and the EU across Korean industry since IFRS adoption, comparability with China has decreased while that with Japan improved.

The purpose of this study was to examine the self-regulation in E-commerce business and review the major issues of self-regulation in several countries. This paper reviewed the legislation for the self regulation of APEC, OECD and EC, and introduced the regulation system for several countries, such as U.S. U.K and Japan. Also, we analyzed the current issues and problems of self-regulation in Korea and tried to suggest the future direction. There were three different regulations such as market forces, government regulation and self-regulation and the model of self-regulations were shaped in various types. Even though the government made the standard regulations for business sector but it was impossible to direct individual firms and their compliance of those regulations. To compensate the government regulation, the self regulation with low cost is needed and also two kinds of regulations has to be unified to enhance the regulation system in E-commerce. Industries should participate for the regulation voluntarily and consumers must give an award of legislation for self-regulation to motivate the self-regulations of industries.

Purpose - We study whether the bullwhip effect is prevalent among Korean firms and how the characteristics of it differ from the ones in other countries. Design/methodology/approach - We obtained quarterly financial and operational information on KOSPI-listed firms in manufacturing, wholesale, and retail industries from 2013 to 2019. We explore the variation of the bullwhip effect across firms and validate hypotheses. Findings - First, we find that for the KOSPI-listed firms, the bullwhip effect is more prevalent compared with the production smoothing. We provide additional findings by using sub-samples of manufacturing firms, wholesaling and retailing firms, big-sized firms, small- and medium-sized firms, domestic-sales intensive firms, and export intensive firms. Second, we show that in general, the bullwhip effect of Korean firms increases with the days in inventory or the demand seasonality ratio. However, the persistence of demand shock does not affect the bullwhip effect of Korean firms. Research implications or Originality - We compare our results with those in other studies that use information on the U.S. and Chinese firms. Our findings show that factors explaining the bullwhip effect across Korean firms have similarities and differences compared with firms in the U.S. and Chinese firms.

Despite the numerous advantages that CSR engagement can potentially offer, top managers may not always be willing to invest in CSR as they are expected to meet expectations of external constituents in the short run. Given that financial analysts' expectations are important short-term performance targets that top managers are motivated to meet, this study examines how performance relative to earnings forecasts issued by analysts affect top managers' decisions about CSR engagement. Using a sample of publicly listed U.S. firms from 2000 to 2016, we find that top managers are more likely to reduce discretionary expenditure on CSR activities as performance falls below analyst forecasts to improve financial performance in the following fiscal year. As performance exceeds analyst forecasts, top managers are motivated to reduce CSR investments in order to meet higher expectations of analysts. As financial analysts closely monitor the firms that they follow in order to publish investment advice to market participants, we find that analyst coverage weakens top managers' incentive to reduce CSR engagement. Overall, this research sheds meaningful insight into the contextual background in which the top managers are situated in when they make decisions on CSR engagement.

Now a days, U-healthcare comes into the spotlight as a new business model which combines RFID technology with medical service in the well-being era and IT popularization. U-healthcare service needs a method that can deals with hand-writing, overlap data, forgery and falsification of data, difference between information version that happen in medical process because of graft between RFID technology and u-healthcare. This paper proposes RFID based user certification protocol to protect user's privacy who gets medical service through U-healthcare. In the protocol, secret information of patient does the XOR with the secret key that is created in the hospital to reconsider the stability of security system of U-healthcare and user's data forgery and falsification and privacy and then saves it in the secret key field of patient in DB table. Also, it informs the case of illegal access to certification server and make it approved the access of u-healthcare service by differentiating whether u-healthcare is illegal or not.
