This thesis examines the problems faced in the clearance procedures of Korea's e-customs system for which improvements are necessary, and suggests various ways of overcoming those problems. Practical implications regarding the advancement of Korea's e-customs system are as follows. First, the substructure of the e-customs clearance system, which is the basis for the establishment of a global single window, should be developed into a more modern and advanced system. Second, additional improvements in the law are required to render the broad array of Internet-based export and import documents legally binding. Third, customized services should be provided in order to improve the operating efficiency of the e-customs clearance system. Fourth, the reputation of Korea's e-customs clearance system should be raised via the strengthening of a cooperative system between concerned parties, including exporters and importers. This innovative approach to systematic improvements will come about when we can simplify current customs clearance procedures and establish a fairer customs inspection administration regime. Additionally, when we review the methods intrinsic to our customs system, we must emphasize the urgency of proper completion of related systems and arrangements in the trade business and similar fields.

For a pressurized water reactor power plant, the reactor coolant pump (RCP) is a kernel component. And for a canned motor RCP, the rotor system's properties determines its safety. The liquid coolant inside the canned motor RCP fills clearance between the metal shields of rotor and stator, forming a lengthy clearance flow. The influence of inlet preswirl on rotordynamic coefficients of clearance flow in canned motor RCP and their effects on the rotordynamic characteristics of the pump are numerically and experimentally investigated in this work. A quasi-steady state computational fluid dynamics (CFD) method has been used to investigate the influence of inlet preswirl. A vertical experiment rig has also been established for this purpose. Rotordynamic coefficients on different inlet preswirl ratios (IR) are obtained through CFD and experiment. Results show that the cross-coupled stiffness of the clearance flow would change significantly with inlet preswirl, but other rotordynamic coefficients would not change significantly with inlet preswirl. For the case of clearance flow between the stator and rotor cans, influence of inlet preswirl is not so significant as the IR is not large enough.

Import Agency Service Mall, providing customers not only with convenient shopping experiences but also with purchasing, warehousing, shipping, and customs clearance services, have been playing a significant role in rapidly transforming Korean consumers into global consumers. The consumers' great demand for foreign goods(services) has created Import Agency Service Mall(referred to hereafter as IASM) as a new business model of distribution and consumption, which seems to be grown rapidly. This empirical research investigates online shoppers for their trust dimensions for IASM. Consequences of the research are as follows: First, perceived reputation, web-site quality have influenced upon e-trust dimension of the IASM. Second, the level of e-trust consumers is more higher, and then the level of perceived risk is more lower. Third, perceived risk have not influenced upon intention to reuse the IASM. Fourth, the level of e-trust consumers is more higher, and then the level of intention to reuse the IASM is more higher. It is necessary for IASM to be developed its reputation and web-site quality in order to obtain customer's trust. Accordingly, this research will be helping IASM have insight for marketing strategies, and constantly should be studied about action and mind of consumer.

FTA체결의 증가, 식품교역 증가 및 소비자의 다양한 식품 선호도 등으로 농축수산물 및 가공식품의 수입량은 매년 증가하고 있는 추세이다. 수입식품의 안전성을 확인하는 정밀검사는 전체 수입식품건수 대비 20%정도를 차지하고 계속 증가하고 있는 반면에 정부의 수입안전관리에 필요한 예산과 인력은 그 한계점에 다다르고 있다. 수입식품 안전사고가 발생하게 되면 막대한 사회적, 경제적 손실을 야기할 수 있으므로 수입식품의 수입허용여부를 정확하게 예측하여 선제 대응하는 것은 수입안전관리의 효율성과 경제성을 획기적으로 높일 수 있게 된다. 식품분야에서는 이미 엄청난 양의 정형 데이터가 과거로부터 쌓여 왔으며 이에 대한 충분한 분석을 통한 활용은 아직은 부족한 것이 현실이다. 전체 수입건수와 중량 중에서 차지하는 가공식품의 비중은 평균 75%에 달하고 있어 식품분야에서도 빅데이터의 분석, 분석기법의 적용 등으로 다량의 데이터로부터 의미 있는 정보를 추출하는 과학적이고 자동화된 부적합탐지시스템의 연구가 절실한 상황이다. 이러한 배경에서 본 연구는 기계학습분야의 다양한 부적합 예측 모형을 적용하였으며 예측 모형의 정확도를 개선시키기 위한 방편으로 새로운 파생변수의 생성을 통한 데이터 전처리 방안을 제시하였다. 또한 본 연구에서는 기계학습분야의 일반적인 기저 분류기를 적용하여 예측 모형의 성능을 비교하였으며 여러 기저분류기 중 Gaussian Naïve Bayes예측 모형이 수입식품의 부적합을 탐지하여 예측하는 가장 좋은 성과를 보여주었다. 향후 Gaussian Naïve Bayes 예측 모형을 이용한 부적합 탐지 모형을 적용하여 수입식품의 정밀검사 비중을 낮추고 부적합률을 제고시킴으로써 수입안전관리 국가사무의 효율성과 수입통관의 신속성에 지대한 효과를 거둘 수 있으리라 기대한다.

In many countries, a Single Window system for simplifications is establishing in order to reduce works submitted double data and compliance costs. A Single Window is defined as a facility that allows parties involved in trade and transport to lodge standardized information and documents with a single entry point to fulfil all import, export, and transit-related regulatory requirements. A Single window can bring improved level of security, faster clearance and reduced compliance costs. UN/CEFACT released "Recommendation and Guidelines on establishing a Single Window to enhance the efficient exchange of information between trade and government". Also, WCO has made progress several projects to assist effective establishing a single window, i.e. CDM, UCR, ICT. Korea has being established a single window system, "e-trade platform" connected with trade, clearance, logistics, marketing and payment system. Some suggestions to establish a effective single window system in Korea are as follows. Firstly, it is necessary to clearly define roles and responsibilities of a lead agency in a single window system and form a organic relationship with PGA. Secondly, a single window system has to be progressed by stages, namely, customs clearance portal system should be established first, and later established e-trade platform. Lastly, the Korean government has to take part in CDM project to gain an advantage over other countries.
