The thesis examines the problems for improvement of clearance procedure and shows the various ways of overcoming them. Practical implications regarding the innovation of clearance procedure are as follows. First, the basis of information for customs clearance service should be built for unifying customs clearance information and imports and exports goods. Second, Customs Service need to keep on trying continuously that customs clearance system should be inter-convertible in the inside and outside of the country. Third, reliable law and execution system should be needed to revitalize customs clearance business and the government need to take measures for new system which is suitable for our own country. Finally, mutual cooperation administration system for customer in domestic and foreign country should be made for supplying high quality clearance service. As we have reviewed above contents, the customs clearance business meet the needs of innovation with new information technique to overcome lots of problems which come by when we execute simplification of customs clearance procedure and customs inspection administration fairly. As well as, when we review a few methods in the line of our customs system, we need strongly completion of related system and arrangements in trade business and similar fields. Hereafter we hope the limitation of this study should be overcome by the process of proper inspections through subsequent studies.

An automotive wheel bearing is one of the most important components to guarantee the service life of a passenger car. The endurance lift of a bearing is affected by many parameters such as material properties, heat treatment, lubrication conditions, temperature, loading conditions, geometry, internal clearance and so on. Under the same geometry and loading conditions, the internal clearance is the most effective parameters on the endurance lift of a bearing. Generally, bearings have the longest lift with a little negative internal clearance. But it is very difficult to measure and modify the internal clearance after a wheel bearing is assembled. In this paper, we analyze the effect of an assembling procedure on the clearance of wheel bearings and suggest a method to determine optimal clearance for automotive wheel bearings by selecting initial bearing clearance.

This paper discusses a clearance pricing on daily perishable products considering a reference price of consumers. The daily perishable products are sometimes sold at a discount price before closing time to stimulate demand when the number of unsold products is more than initially envisioned. The discount pricing results both in an increase of the revenue of the day and in a decrease of the disposal cost. The discounting, however, also declines a reference price of consumers which is a mental price and serves as an anchor price to judge if a current sales price is loss or gain for the consumers. An excess discounting decreases the demand for the products sold at a regular price in the future and diminishes long-term profit. This study conducts a mathematical analysis on the clearance pricing problem for a single period with stochastic variations both on demand and on the inventory level at clearance time. The expected profit function especially depends on the response of consumers to the clearing price against their reference prices. A procedure is proposed to derive an optimal clearance price when consumers are loss-neutral. A sufficient condition is shown to obtain an optimal price for loss-averse and loss-seeking consumers by an analogous procedure.

CPDLC-DCL (Controller Pilot Data Link Communications-Departure Clearance) began in 2016 with 62 Towers in the United States. The application of this procedure is to utilize equipment different from existing ACARS PDCs or ACARS-DCLs. The purpose of this study is to provide information and understanding of CPDLC-DCL operation methods. Also, B747-8 aircraft considered operational cases related to departure procedures at U.S. airports. This procedure is currently not mandatory but will be mandatory in the future. The Flight Crew Procedures for CPDLC-DCL, as an appendix, will be a useful resource for B747-8 pilots.

Globalization of consumption, expansion of cross border e-trade, increase use of internet and mobile have led to rapid growth of world e-commerce particularly in Asia and emerging markets. Impacted by Korean wave, online export is continuously increasing, yet Korea is experiencing severe e-commerce trade imbalance. Export growth rate and ratio of Korean small companies are relatively low from OECD member countries. Therefore, Korean government is currently emphasizing on vitalization of online export to China to resolve trade imbalance and to increase export of small companies. To propose detail measures to vitalize online export to China, this study is focused on export customs clearance procedure of Korea and import customs clearance procedure of China in view of online export company. Also suggested countermeasure plan and analysis for the new tax revision plan related to e-commerce which implemented on April 8th 2016. This study have grouped countermeasure plan by short term plan of firms and long term plan of the government. As for the short-term countermeasure plan for firms, first, comparison analysis of tax rate on products is need to decide type of e-commerce strategy; second, if planning to start e-commerce business to China, sales possibility and certification check is necessary; third, through preparation of customs clearance document is needed; last in order to obtain price competitiveness, new logistics strategy and packing development is required. As for the long-term countermeasure plan for the government, I have suggested cooperated bonded logistics service for small businesses and operation plan of show room for promising Korean products.

As the upending is one of the critical steps in the installation of offshore structure, datail procedure of upending operation is studied in the paper. For larger offshore structure installation, launching method is often applied. However after launching, the upending process is to be followed. To ensure successful upending operation, datail process is analysed considering various factors affecting on the operation including reserved buoyancy, free flotation position, seabed clearance, ballast and hook load. To investigate the influence of each factor on the procedure, twelve numerical jacket models with various dimensions are simulated and studied. From the study, it is revealed that the increase of buoyance and decrease of self weight generate a large seabed clearance. The law seabed clearance during flooding creates higher hook load and height. The paper also introduces a guideline for the related structure design and construction with the effects of contribution factors in the upending operation.

Recently, Electronic commerce market is growing sharply for the expansion of internet and development of means of air transportation. Import Clearance System for express consignments, introduced in Korea, confers some benefit upon express consignments, ie. prompt clearance, simplification of the clearance procedure, exemption of necessary documents. But it has some problems such as lack of social security and trade compliance. So it requires some improvements as follows. Firstly, it has no legal background to clear all articles valued at US$100 or less carried by an express consignment operator. So customs brokers, not express consignment operators, should clear that articles. Secondly, it should be presented necessary documents including commercial invoice to prevent a wrong price declaration in entering express consignments valued at US$100 or less. Thirdly, X-ray inspectors must enhance their inspection ability. Customs must provide education programs for X-ray inspectors to improve their inspection ability. Lastly, Cargo selectivity system for express consignments have to be improved to operate effectively.

지식재산권 침해여부를 판단하는 것은 전문적인 지식이 필요할 뿐만 아니라 상당한 시간이 소요되므로 신속한 통관을 추구하는 무역원활화라는 명제와 철저한 심사를 통한 사회 안전 및 권리의 보장이라는 상반된 명제를 조화롭게 아울러야 한다는 관세행정의 과제 앞에서 범죄수사와 관련이 있다면 통관절차의 일부분인 물품검사에도 형사법상의 통제가 있어야 한다는 논의가 있다. 그런데 관세법은 관련 규정들을 살펴보더라도 지식재산권 침해물품에 대하여 조사부서에 송치를 의뢰하더라도 그전에 이를 적발하기 위한 물품검사 등에 대하여는 행정적 의미에서의 조사일 뿐 형사법적 통제를 받는 검사 내지 조사는 아니라고 보는 입장인 것으로 보인다. 관세법상의 물품검사가 형사법상의 수사의 단서로서의 성격을 갖고 기능을 한다는 것은 우범성 선별검사를 포함한 통상적인 물품검사의 경우에 국한 된다고 할 수 있다. 만약 특정한 범죄정보로서 특정한 물품을 검색한다는 것은 그 자체로서도 이미 범죄의 혐의를 갖고 수사를 개시하였다고 봄이 타당하므로 해당 개장조사의 경우 수사행위로서 형사법상의 규율을 받아야 한다. 이렇게 해석해야만 관세고권에 바탕을 둔 통관절차상의 물품검사와 형사법상의 강제처분인 압수 수색간에 조화로운 운용의 묘를 찾을 수 있는 계기가 될 수 있을 것이다.
