정부는 그동안 항공정책을 수립하고 시행함에 있어서 '항공운송'과 같은 경쟁력 있는 부문만을 특정하여 중장기적인 발전전략을 수립하여 온 것이 사실이다. 지방공항은 처음부터 물적, 인적 자원을 수송하는 규모나 주변 환경여건에 있어 국제공항을 따라갈 수 없는 일정한 한계를 가지고 있다. 지방공항의 적자문제를 국제공항의 목표치에 두는 것 자체가 이치에 맞지 않기 때문이다. 그러므로 지방공항은 국제공항과는 다른 관점의 항공 정책이 절대적으로 필요하다. 국가전체의 운송기능 향상을 위한 종합적인 대책도 지방 공항에 적용할 필요가 있지만 지방 공항 고유의 지방자치단체와의 협력을 통한 특색 있는 공항 역할을 재정립하는 것도 필요한 것이다. 한편 항공 스포츠의 역사는 60여년에 이르고 있으나 정부 관련기관의 관심 부족과 활성화 하려는 의지부족으로 여전히 침체되어 있는 것이 사실이다. 그런데 본 연구에서 항공 스포츠의 특징상 공항과의 연계성을 검토하여 보니 상당히 긍정적인 Win-Win 전략이 될 수 있을 뿐 아니라 지방공항과 항공 스포츠 양자가 실제 활성화될 수 있는 공항정책이 구체화될 수 있음을 알게 되었다. 다만 항공 스포츠에도 종목이 다양하므로 지방공항의 특성상 적정한 스포츠 항목과의 연계가 요구된다. 그리하여 본 연구는 항공 스포츠를 활용한 지방공항 활성화 방안으로 항공 스포츠에 적합한 지방공항 요건을 접근성, 안전성, 편의성으로 나누어 검토하고 지방공항과 접목 가능한 항공 스포츠를 제시하고자 하는 가설을 설정하였다. 더 나아가 항공 스포츠를 통한 지방공항 활성화의 기대효과로서 지방공항의 활성화, 지방연계산업의 활성화, 지방공항의 발전 가능성에 대한 가설을 설정하였다. 본 논문은 지방공항 활성화를 위한 전략체계를 항공스포츠 동호인 즉 조종자들의 기지선택 요인을 중심으로 실증분석을 통하여 정리하였고, 일반인들의 인식과 전문가 의견을 토대로 지방공항의 활성화를 위하여 항공스포츠와 전략적 제휴를 하고자 할 경우 관련기관들이 고려할 부분과 운영체계 개선방안을 제시함으로써 구체적인 정책적 제언이 될 수 있도록 하였다.

This study aimed to select and evaluate policy priorities for the expansion of public and semi-public systems for coastwise passenger transport services. For research methodology, the Consistent Fuzzy Preference Relations (CFPR) method was used to effectively extract expert knowledge. First, the result of the analysis on policy tasks for expanding the semi-public system for coastwise passenger transport services showed that "the establishment of public transportation fare system" was the most important task at 0.160. Second, "conversion of the subsidiary routes to a public system by the central government" was ranked next at the importance of 0.136. The factor named "support through proper allocation of budgets between national and local governments" are ranked third (0.119). The results of this study have practical implications in that it proposed the policy priorities for the expansion of the public semi-public systems for coastwise passenger transport services.

기존의 미국 식품의약국(FDA, Food and Drug Administration)규정에 따르면 어떤 식품첨가물의 기능과 안정성을 평가하는 방법은 그때 그때 각각의 경우에 맞게 설정하여 실시하게 되어 있다. 이런 평가 방법은 포괄적이기는 하지만 과잉의 기능과 안정성 시험을 실시하는 결과를 초래해 왔다. 여기서는 새로운 식품 첨가물에 대한 안정성 시험 시 그 첨가물이 사용되는 실제 조건 하에서 체계적이고 과학적인 접근 방법에 따라 시험이 되도록 할 것을 제안하고자 한다. 체계적인 방법으로 시험하기 위해서는 새로 개발된 식품첨가물들이 사용하게 될 적용 대상 식품의 여러가지조건(pH, 수분, 가공 및 저장 온도)에서 그 첨가물의 안정성에 영향을 미치는 화학적, 물리적 주요 요인들이 먼저 결정되어야 한다. 그 다음 기능성과 안전성에 관련된 요소들이 하나의 모델 시스템으로 조직화되어 주요요인들의 측정 범위가 정해져야 한다. 마지막으로 설정된 모델 시스템은 첨가물이 실제 적용받게 되는 가공,운송, 저장 조건 하에서의 사용 조건을 고려한 상태에서 첨가물을 시험하여 기능과 안정성이 입증되어야 한다. 일단 증명이 되면 그 모델 시스템은 사용 가능성이 있는 적용 범위에까지도 그 첨가물의 기능성과 안정성을 평가할 수 있게 해준다. 이 논문에서는 식품첨가물 시험방법에 대한 체계적인 접근 방법을 설명하고 아스파탐의 예를 들어서 그 방법을 조명해 보고자 한다.

In this paper, I explain the situations and problems which are focused on the rail freight system. We have a many problems, which have been showed the long freight logistics time, and inadequate fare system. And rail freight system does not have a efficient marketing system, and unit load system. Therefore rail freight has been decreased modal share, which is estimated from 9.65% in 1995 to 6.25% in 2001(ton base). Recently, EU nations and America rail freight system reveals a good outcome, which keeps the balance in the black. The main factors which go into the black, is the enlargement the investment in rail freight and efficient management focusing on the unit load system, fare system, and personnel management. I suggest the several improvement ways, which will be helpful to advance the rail freight system. Fistly, I suggest the speed up the freight rail and efficient fare system. Secondly, I propose the unit load system and the regulation the truck focusing on curtailment of the social cost. Lastly, I make an overture of establishment the comprehensive logistics system.

The Donghachong tomb from Royal Tombs at Neungsanri is composed of 15 sides including the floor, and the most highly proportion of rock, two-mica granite, are used on the 7 sides (46.6%). Also, augen gneiss consist with another 3 sides (20.0%), and each of the remaining 3 sides (6.7%) are made up of granodiorite, gneissous granite and leucocratic granite, all of which were used to comprise the tabural stone. Meanwhile, the two floors of the burial chamber and the front chamber, are made up of brick-shaped amphibole schist (13.3%). These rocks are occurred in the Buyeo area and their provenance sites are located at the side of Guemgang river. The Memorial Stone for Liu Renyuen in Tang China is a typical augen gneiss showing distinct schistosity and augen texture. This rock has the same petrographic characteristics with the rocks used to build the Donghachong tomb, Sanjikri dolmens and Setapri pagoda in Buyeo. This augen gneiss is distributed from the Jeungsanri in Buyeo to Dukjiri in Gongju as a large scaled rock body, and where currently are the quarries to produce stone aggregates, garden and landscape rocks. Thus, it is highly probable that the site around Buyeo was the source area of augen gneisses since the Bronze Age. However, while augen gneiss is easier to form into shapes it should have disadvantages when it comes to painting on the tomb wall because of their petrographic characteristics of low strength and dark color. Therefore, it is very intriguing to investigate which transportation method the people of Baekje chose with consideration of the distance and terrain, efficiency and convenience.

The Northeast Asian air cargo market has expanded tremendously as a result of the opening up of the Chinese market. The importance of the Asia-Pacific region in the global air transport has also increased. The exchange of human and material resources, services, and information in Northeast Asia, which is expected to increase in the near future, requires that the airlines operating within this region adopt a more liberalized approach. This paper introduced alternatives which can be applied to the Northeast Asian airlines industry so as to bring about the integration of regional air transport: First, this paper found a need for individual Northeast Asian nations to alter their policies towards the airlines industry. Second, each country should further liberalize their respective domestic air transport. Third, there is a need for freer air service agreements to be signed between the nations of Northeast Asia. Fourth, the strategic alliances between the airlines operating in Northeast Asia should be further strengthened. Fifth, this liberalization process should be carried out in an incremental manner, beginning with more competitive airports and routes, or with less-in-demand routes. Sixth, there is a need for a shuttle system to be put into place between the main airports in China, Korea, and Japan. Seventh, these three nations jointly develop aviation safety and security systems that are in accordance with international standards. Eighth, the liberalization process of the aviation industry should be undertaken in conjunction with other related fields. Ninth, organizations linking together civil aviation organization in the Asia-Pacific area should be formed, as should each government linking together. By doing so, these countries will be able to establish regular venues through which to exchange opinions on the integration and liberalization of the air cargo market so as to induce the gradual liberalization of the actual market. The liberalization of the air transport in Northeast Asia will prove to be a daunting task in the short term. However, if the Chinese airlines continue to exhibit continuous growth and Japanese airlines are able to complete their move towards a low-cost structure, this process could be completed earlier than expected. Over the last twenty five years the air transport has undergone tremendous changes. The most important factor behind these changes has been the increased liberalization of the market. As a result, rates have decreased while demand has increased. This has resulted in turning the air transport industry, which was long perceived as an industry in decline, into a high-growth industry. The only method of increasing regional exchanges in the air transport is to pursue further liberalization. The country which implements this liberalization process at the earliest date may very well emerge as a leading force within the air transport industry.

The Integrated Public Transport Reforms of the Seoul Metropolitan Government, which were implemented on the $1^{st}$ of July. 2004, launched a new fare allocation method. However, when a Private transit operator or a new transport system is introduced into the existing system, it will cause an allocation problem. Therefore, this study aims to Propose a rational fare allocation method which can be applicable regardless of the number of Public transportation modes or operators. To create alternatives, this study has adopted a fundamental principle of revenue allocation methods for the transit or communications sectors, and has applied it to the current transit system of Seoul. This study kas analyzed results of the cost recovery ratios and characteristics of each alternative through case studies. This study kas Presented an assessment criterion Z in order to select an optimal alternative. The criterion consists of the sum of the cost recovery ratio of each operator and the difference of the cost recovery ratio for each agency in inter-agency transit. Using the assessment criterion. the results showed that Alternative 1 is superior to the others : Alternative 1 is considering passenger-km of each operator and unit cost of passenger-km for each operator.

The purpose of this paper is to estimate economic benefits for the investment of railway transshipment system with non-powered turntable. The freight transport by railway can have decided advantages over trucks in terms of energy efficiency, emissions and cost for certain freight movements, just as transportation in the metropolitan region can have great advantages over driving truck. But the freight transport by truck should gain significant mobility benefits from a freight railway system. Thus, the railway transshipment system with non-powered turntable which is coupled railway transport advantages with load transport advantages has been developed and used in the european countries. This research has conducted the empirical analysis, by calculating the investment of railway transshipment system with non-powered turntable. The key factor for the economic benefits for the non-powered turntable is the utilizing throughputs. This demand is influenced by the throughput in the railway transshipment system. The main results of this paper are as follows: railway transshipment system with non-powered turntable does not have economic benefit for investment. We recommend that the plan for investment has to be considered the modification.
