This study reviews maritime transport policy regarding liner conference and the changes in the liner market over the decades. Liner shipping industry has long been protected from competition by block exemption. To prevent excessive competition in punctual operation and its inelastic market structure, liner shipping companies formed conferences that are protected to fix the prices under the law. In the US, deregulation in transport sector began from 80's and continuing with OSRA 1998, conferences were dissolving. On the other hand, the EU with close conference system, Regulation 4056/86 contained block exemption remained in force for unlimited time without review clause. However, in Oct 2008, the EU has announced its removal, and conferences were no longer permitted to fix the price nor exchange information. Although OSRA 1998 has already broken up conferences by allowing individual service contracts, but the repeal of the immunity for price fixing will alter significantly the rule on cooperation in the industry since it is a unilateral move by the EU, especially in transatlantic lane. There are rapid changes in shipping market getting much more complicated, and with removal of 4056/86 allowing the market to be more competitive, opening up the industry with far more diverse strategic options. Hence this paper reviews on liner shipping industry and its changes of policies over the years from protected market to open competition market of today.

Since the late 1980s, an Increasing number of neural network models have been studied in the areas of financial prediction and analysis. The purpose of this study is to Investigate the possibility of building a neural network model that is able to construct a profitable trading strategy in the Korean Stock Market. This study classifies stocks into the future market winners and losers from the publicly available accounting information and builds portfolios based on this information. The performances of the winner portfolios and the loser portfolios are compared with each other and against the market index. The empirical result of this research is consistent with the traditional fundamental analysis where it is claimed that the financial statements contain firm values that may not be fully reflected In stock prices without delay. Despite the supporting empirical evidence. It is somewhat Inconclusive as to whether or not the abnormal return in excess of market return is the result of the extra knowledge obtained in the neural network models derived from the historical accounting data. This research attempts to open another avenue using neural network models for searching for evidence against market efficiency where statistics and intuition have played a major role.

Vietnam is gaining much attention as an attractive emerging market that can replace BRICs for the corporations who are destined to always look for a new market in order to secure competitive powers in the global market. The reason for Vietnam's becoming an attractive place for production is that much uncertainty has been found in China, which has been the traditional country that absorbed the most amount of capital investment. Also, the favorable conditions of Vietnam market itself and the environmental changes such as the open-door policy of Vietnam government attract the investment of Korean companies, and Korea currently holds the most amount of cumulative investments in Vietnam. However, it is necessary to remember that Vietnam is still a socialist nation, and many required components for corporate activities are not sufficiently provided in Vietnam market. Also, many unstable environmental factors exist such as the lack of infrastructure, the lack of many required institutions, the prevalent corruption, the excessive processing time and cost for adjusting the investment, the lack of advanced work force, and the underdevelopment of part and material industry. Therefore, those companies who are planning to invest in Vietnam should take a long-term perspective in planning the investment strategies, carry out a detailed market investigation and analysis in advance, diversify the investment areas and investment sectors, carefully make a joint venture and management, carefully determine the factory location, establish a local agency, make co-investments with the part suppliers, etc.

Purpose - This study investigates the performance of investment strategies incorporating estimated stock market cycle based on a lead-lag relationship between business cycle and stock market cycle, thereby deriving empirical implications on risk management. Design/methodology/approach - The data period ranges from June 1953 to September 2022 and de-trended short rate, term spread, credit spread, stock market volatility are considered as major input variables to estimate business cycle and stock market cycle by applying probit model. Based on the estimated stock market cycle, two types of strategies are constructed and their performance relative to the benchmark is empirically examined. Findings Two types of strategies based on stock market cycle are considered: The first strategy is to long(short) on stocks when stock market stage is expected to be an expansion(a recession), and the second one is to long on stocks(bonds) when expecting an expansion(a recession). The empirical results show that the strategies based on stock market cycle outperforms a simple buy and hold strategy in both in-sample and out-of-sample investigation. Also the out-of-sample evidence suggests that the second strategy which is in line with asset allocation is more profitable than the first one. Research implications or Originality The strategies considered in this study are based on the estimated stock market cycle which only depends on a few easily available financial variables, thereby making easier to establish such a strategy. It implies that investors enhance investment performance by constructing a relatively simple trading strategies if they set their position on stocks or choose which asset class to buy conditioning on stock market cycle.

본 연구는 지난 10년간 급격하게 변화하여 온 온라인 쇼핑산업에 대해 성장의 동력을 이론적으로 확인하고, 이들에 의한 이론적 설명을 시도한 탐색적 연구이다. 이러한 과정에서 이론적으로 선점이론에 대한 검토를 통해 이 이론이 유통구조에서 온라인 유통산업에서 발생하고 있는 재중간상화와 배치됨을 확인하였고, 이에 따라서 동적 역량이론을 활용한 온라인 산업에 대한 이론적 적용모델인 NEBIC에 대한 검토를 통해 동적성장이론인 이중나선구조 모형을 제안하였다. 또한 이론의 현실적합성을 확인하기 위해 2000년에서 2008년 한국 온라인 쇼핑산업의 발전과정을 재구성하고 각 기업의 매출자료 및 총매출액을 검토하여 현재 진행 중인 온라인 유통업의 동적 성장과정에서 각 기업의 역량이 시장에 적용되어지는 과정을 확인하고 새로운 진화방향을 제시하고자 하였다. 이러한 과정을 통해 보았을 때, 오픈마켓의 주도를 통한 시장 발전은 한계에 봉착한 것으로 보인다. 따라서 향후 온라인 쇼핑몰은 자기 기반 역량 위에서 유통경로 구조 전반에 걸친 유통기능의 개발과 상품개발을 통해 경로구조를 통합하는 방향으로 발전할 것으로 잠정적 결론을 내릴 수 있을 것이다. 이러한 결론에 기반하여 오픈마켓에서 육성된 대형 판매자들의 전문몰화, 상장기업화를 유도하는 한편, 상품취급범위를 제한하는 다양한 정책 및 규제를 통합운영하고 조정하는 컨트롤 타워의 구축, 그리고 오픈마켓의 중소 상인육성기능을 강화하기 위한 인센티브의 구성과 같은 정책적 제안이 제시되었다.

Purpose - Lettuce (Lactuca sativ L.) is one of the economically important vegetable crops, which worldwide market value is over 100 billion U.S. dollar. In Korea, about 89.7 kilo ton of lettuce was produced in 3400ha in 2016, recoded as No. 1 vegetable crop in domestic green house production. However, recently, domestic lettuce production and cultivation areas are all getting decreased. Thus, novel approaches are needed to be implemented to revive the production. Research design, data and methodology - In this review paper, we first prioritized the end-user traits which are imperative to positively stimulate the domestic lettuce market and discussed relevant genomics strategies. Especially, we assessed a possibility whether school meal program would be a potential niche market. Results - The genomics technologies, which become widely applied in the crop biotechnology since 2008 when next generation sequencing method was developed, may be a good solution in the crop improvement, efficiently gathering valuable information of agriculturally useful traits. Significantly, in lettuce, the high quality whole genome sequence, based on Lactuca sativa cv. Salinas, is publically available and this genomics platform, thus, would be implemented in lettuce breeding program to innovate relevant end-user traits both for the farmers and customers, including the disease resistance to the Fusarium wilt, productivity under hot weather conditions, various nutritional qualities and so forth. These improvements will boost domestic lettuce industries in the near future. Conclusions - Due to the nutritional distinctions comparing to the western style lettuces, domestic leaf lettuces could be one of the important vegetables in the school meal programs. To make it happen, we would better devise diverse recipes to make a salad with it, instead of only using as a wrap vegetable. Meanwhile, novel lettuce varieties need to be developed, which are favorable to the students and also easy to be handled with while processing. Overall, to achieve international competence in the lettuce industries, we need to create elite lettuce varieties that satisfies domestic farmers as well as customers, suitable to various niche markets, such as school meal program. Thus, efficient breeding programs using genomics approaches should be established in advance and careful monitoring on the preference of the related customers for a niche market be continued persistently.

본 연구는 한국의 천연가스시장에 경쟁을 도입하는 정책이 사회후생에 미치는 영향을 이론적으로 분석하였다. 기존의 독점기업은 천연가스의 저장/운송을 위한 필수설비를 보유하고 있으나, 경쟁도입을 위해 신규기업 진입 시 필수설비를 공유해야 하는 의무를 지게 되었다. 독점기업이 천연가스의 가격과 필수설비 접속료를 자유롭게 설정할 수 있는 경우, 신규기업의 진입은 사회후생을 증가시킬 뿐만 아니라 독점기업의 이윤도 증가시킨다. 그러나 정부가 가격규제를 시행하는 경우, 설비 운용비용에 대한 정보의 비대칭성이 있는지의 여부에 따라 사회후생이 결정된다. 정부가 완전한 정보를 가지고 있는 경우에는 사회후생을 극대화하는 선택을 쉽게 유도할 수 있으나, 그렇지 않은 경우 정부는 불완전한 정보를 바탕으로 가격규제를 시행하게 된다. 본 연구에서는 정부와 기업들의 의사결정을 베이지안 게임을 통해 분석하여, 완전 베이지안 균형 아래서 독점기업이 공개하는 정보의 양에 따라 사회후생이 어떻게 변화하는지 살펴보았다.

As The Fourth Industrial Revolution and Intelligent Information Age came into full-scale, the policy of open government data has become a hot topic for each country. The United States, the United Kingdom, and other countries are shifting policy direction to "creating value" of open government data. Also, in the age of the digital economy where the data market is soaring, open government data is gradually being recognized as a new raw material for new business and start-ups. In addition, Korea ranked first in the OECD open government data evaluation twice in a row, and was highly evaluated in the international evaluation. However, domestic firms are still lacking in qualitative openness of government data, data is dispersed among institutions, lack of public-private data linkage, and development of app-oriented development. This study attempts to analyze major national policies for the creation of a data ecosystem that considers data lifecycle, from production to storage, distribution and utilization of data. First, the target countries were the leading public data countries among the OGP member countries, the USA, the UK, Australia and Canada. The results of this study are as follows. As a result of analyzing the results and comparing Korea's policies, it was concluded that most of Korea is superior in open government data policy. However, improvement of data quality, development of open data portal as an open platform, support for finding various users including apps and web development companies, and cultivation of open government data utilizing personnel are analyzed as policy issues. In addition, the direction of policy for the balanced ecosystem of Korea is presented together.

미국의 탈퇴 이후 불확실성이 많지만, TPP는 정부조달 시장개방에 소극적이었던 베트남, 말레이시아, 브루나이, 멕시코 등의 주요 중진국들의 정부조달 시장을 개방하는 데에 성공하였다. 본 글에서는 현재 가장 큰 규모의 세계 정부조달 시장개방 협정인 WTO GPA와 TPP의 조건들과 규정을 비교하면서 어떻게 TPP가 이 국가들의 시장을 개방하였는지에 대한 함의를 얻고자 한다. 시장개방범위 및 하한선 차원에서 TPP 정부조달 분야의 가장 큰 특징은 정부조달 시장개방에 소극적인 중진국들에게 20년까지의 전환기간을 부여하고, 하한선을 단계적으로 내리게 했다는 점이다. 또한, TPP는 GPA에 비해서 개도국 정부기관들의 행정적 부담 및 비용을 낮추어 주고자 하고 있다. 정부는 새로운 정부조달 시장개방 협상에서 정부조달 시장의 개방을 위해 위의 협상 전략을 고려할 필요가 있다.
