The inflection S-shaped software reliability growth model (SRGM) proposed by Ohba(1984) is one of the most commonly used models and has been discussed by many authors. The main purpose of this paper is to estimate the parameters of Ohba's SRGM within the Bayesian framework by applying the Markov chain Monte Carlo techniques. While the maximum likelihood estimates for these parameters are well known, the Bayesian method for the inflection S-shaped SRGM have not been discussed in the literature. The proposed methods can be quite flexible depending on the choice of prior distributions for the parameters of interests. We also compare the Bayesian methods with the maximum likelihood method numerically based on the real data.

본 논문에서는 우리나라 수출입 등 통관의 전반적인 것을 담당하는 전자통관시스템의 문제점을 발굴하고 개선점을 찾아 보완하여 보다 진화된 양질의 전자통관시스템으로 개발하는 것을 목표로 하고 있다. 전자통관시스템의 문제점을 중심으로 구분하면 통관업무, 사전검증시스템, 데이터정제시스템으로 볼 수 있다. 각 부분별로 문제점을 분석한 결과 오류 데이터 전송, 자가진단 점검기능 부재, 경험치로 관리, 사후관리 체계 부재, 오류분석 기능 미활용으로 나왔으며, 이런 문제점을 해결하기 위해 개선방안에 대해 면밀히 검토하여 맞춤형 대책을 마련하여 처음 신고인이 양질의 정보를 정확히 입력할 수 있는 시스템 구축부터 검증시스템을 통해 정확한 정보를 정제하는 중간단계를 거쳐 마지막으로 최상의 결과를 도출 및 제공하기까지 시스템을 향상시켜 이용객에게 더욱 정확한 처리결과 제공 및 진화된 국가행정시스템을 구축함으로써 국가경쟁력을 강화할 수 있다.

This study analyzed the recent precedents of the Korean Supreme Court's Royalty and License fee on this issue and presented implications for future taxation of Royalty and License fee and digital content imports related to reproduction rights. If the price related to imported goods and the price not related to them are combined, it is necessary to revise the statutes to supplement the allocation method of royalty and license fee. In addition, if there is an agreement or a back contract for intellectual property rights through the headquarters or branch office other than the trading party, a method of inducing the importer to voluntarily report it when reporting imports should be considered. Whether Royalty and License fee is taxed or not must be determined after examining the various contract details and circumstances of the transaction.

This study analyzed that the effects of AEO MRA benefit on decreasing of trade cost and the strategies for expanding of trade. It uses the system GMM for effective solutions of endogenous matter with lagged dependent variable. In terms of the result of analysis, AEO MRA has a positive effect on decreasing of trade cost, especially this study proved the result of previous study AEO MRA expanded the trade through improving the time required for customs clearance and deregulation of non-tariff barriers. In conclusion, this study proposes the policy fo AEO MRA by analyzing the trade cost of AEO MRA by using the system GMM.

For customs-free and liberalization on the trade of aircraft parts, the WTO Agreement on Trade in Civil Aircraft was separately concluded as plurilateral trade agreement at the time of launching WTO in 1995, and currently 33 countries including the United States and the EU are acceded but Korea does not. Major details of the Agreement on Trade in Civil Aircraft include product coverage, the elimination of customs duties and other charges, the prohibition of government-directed procurement of civil aircraft, the application of the Agreement on Subsides and Countervailing Measures, and the consultation on issues related to this Agreement and dispute resolution. Article 89 paragraph 6 of the current Customs Act was newly established on December 31, 2018, and the tariff reduction rate for imports of aircraft parts will be reduced in stages from May 2019 and the tariff reduction system will be abolished in 2026. Accordingly, looking at the impact of the Agreement on Trade in Civil Aircraft on the aviation industry, first, as for the impact on the air transport industry, an tariff allotment of the domestic air transport industry is expected to reach about 160 billion won a year from 2026, and upon acceding to the Agreement on Trade in Civil Aircraft, the domestic air transport industry will be able to import aircraft parts at no tariff, so it will not have to pay 3 to 8 percent import duties. Second, as for the impact on the aviation MRO industry, if the tariff reduction system for aircraft parts is phased out or abolished in stages, overseas outsourcing costs in the engine maintenance and parts maintenance are expected to increase, and upon acceding to the Agreement on Trade in Civil Aircraft, the aviation MRO industry will be able to import aircraft parts at no tariff, so it will reduce overseas outsourcing costs. If the author proposes a policy direction for the trade liberalization of aircraft parts to ensure competitiveness of the aviation industry, first, as for the tariff reduction by the use of FTA, in order to be favored with the tariff reduction by the use of FTA, it is necessary to secure the certificate of origin from foreign traders in the United States and the EU, and to revise the provisions of Korea-Singapore and Korea-EU FTA. Second, as for the push of acceding to the Agreement on Trade in Civil Aircraft, it would be resonable to push the acceding to Agreement on Trade in Civil Aircraft for customs-free on the trade of aircraft parts, as the tariff reduction method by the use of FTA has limits. Third, as for the improvement of the tariff reduction system for aircraft parts under the Customs Act, it is expected that there will take a considerable amount of time until the acceding to the Agreement on Trade in Civil Aircraft, so separate improvement measures are needed to continue the tariff reduction system of aircraft parts under Article 89 paragraph 6 of the Customs Act. In conclusion, Korea should accede to the WTO Agreement on Trade in Civil Aircraft to create an environment in which our aviation industry can compete fairly with foreign aviation industries and ensure competitiveness by achieving customs-free and liberalization on the trade of aircraft parts.

Sungkyunkwan was the highest national education institute of confucianism in the Chosun dynasty. from the historical view of foodservice in Korea, Sungkyunkwan dining room(進士食堂) might be the oldest systematized school foodservice and it was thought that the Korean word of dining room(食堂) was originated from this. The Sungkyunkwan dining room was built in the period of King Tae-jong(太宗) in 1413 and developed during 500 years through the Chosun dynasty. The dining room was not only an eating place but also providing the specific food culture of students. About 200 students studied in Sungkyunkwan and they lived together, and the government of the dynasty made many rules and by-laws to regulate them. Wonjeom(圓點) regulation was one of them. Wonjeom(圓點) was recorded in the register of attendance(到記) in the dining room and the students could obtain 1 point if they attended at the dining room in the morning and the evening in one day. If the students did not obtain the certain points of Wonjeom, they were not qualified for the national examination(大科). And there were so many eating customs and self-regulations in the dining room they were referred in many literatures, such as ${\ulcorner}$the true records of the Chosun dynasty(朝鮮王朝實錄)${\lrcorner}$, ${\ulcorner}$Taehak-Ji(太學志)${\lrcorner}$ and ${\ulcorner}$Banjungiabyoung${\lrcorner}$. In this study, poems in $\boxDr$Banjungjabyoung$\boxUl$, about the Sungkyunkwan dining room and the eating customs such as the eating etiquettes, the daily 8 menu items, the special menus and the special day food, and the bestowal foods of King were reviewed.
