The Earth observation imagery from satellite provide valuable informations for the central government, local governments and diverse public organizations. The analysis of applications and data, which are sold by commercial distributors of Earth observation satellite data, shows this phenomenon clearly. The Government of Republic of Korea established and carried out a national space development plan to meet the national needs for remotely sensed imagery. After this national space development plan and on behalf of Korean government KARI has developed and launched successfully the KOMPSAT-1 and operates it up to now. KARI is now to launch by the end of year 2005 another optical remote sensing satellite with very high resolution and named as KOMPSAT-2. For the application of such very high resolution remotely sensed data the product validation should be done carefully and this product validation require lots of ancillary data such as in-situ measurements. For the purpose of diverse ancillary data acquisition joint work with other nations, related institutes and international bodies is essential. In this paper the status of Korean European Cooperations will be introduced, which are derived by KARI, ARCS and ESA for the wide use of KOMPSAT data in Europe.

로티퍼는 해산어와 담수어뿐만 아니라 식용어와 관상어에 이르기까지 모든 어류의 인공 종묘 생산 과정에서 초기 먹이생물로 이용되고 있는 중요한 동물 플랑크톤이다. 그리고 로티퍼를 초기 자어의 첫 먹이로 사용하는 것을 시작으로 알테미아, 코페포다 또는 초미립자 사료 등을 사용하는 어류 인공종묘 생산 과정에서의 먹이계열이 확립되어 있다. 그러나, 사육하고자 하는 어종에 따라 초기 자어기에서 로티퍼를 섭이하는 시기와 사육 일령별 자어의 로티퍼 포식수를 알 수 있는 정확한 방법이 없다는 이유로 지금까지는 자어의 로티퍼 최초 포식 일령 및 로티퍼 포식수를 개개의 연구자들 나름대로의 방법으로 관찰하여 왔다. 일반적으로 자어가 로티퍼를 포식하였는지의 여부 및 포식수는 자어 소화기내에 존재하는 소화가 진행되기 전의 로티퍼 몸체의 수를 계수하는 방법으로 이루어졌다. 로티퍼의 체내에는 섬모환으로 모은 수중의 먹이 현탁액을 소화기계로 이동시키기 전에 먹이를 잘게 다지고 부수는 기능을 하는 저작기 (trophi)가 존재한다. 그리고 이 저작기는 로티퍼의 종에 따라서 다른 형태를 하고 있는 것으로 알려져 있다. 이 연구에서는 자어가 섭이한 로티퍼는 어류의 소화기내에서 소화가 진행되는 과정에서 로티퍼의 체 구조 중 저작기가 쉽게 소화되기 어렵고 소화기관의 연동 운동에 의해서도 쉽게 그 모양이 손상되지 않는다는 것을 발견하고 이 저작기의 수를 계수하므로서 로티퍼의 최초 섭이 일령 및 일령별 로티퍼 포식수를 계수할 수 있는 방법을 검토하였다. 그 결과, 소화기내의 잔존 로티퍼 몸체만으로 계수 관찰하던 기존 방법에 비교하여 로티퍼의 저작기를 계수하는 방법을 이용할 경우 보다 신뢰도가 높은 결과를 도출할 수 있음을 확인하였다. 경제적 가치의 우수성 때문만은 아니다. 미국은 자국의 대두 생산자들이 생산해 낸 대두를 판매하면서 조성한 자조금을 모아 대두의 생산성을 향상시키기 위한 연구 개발과 국내외 시장을 확대하기 위한 마케팅 활동에 쓰고 있다. 이런 자조 노력은 비단 미국의 대두 농민들에게만 국한된 것이 아니다. 가깝게는 일본의 수산업과 해산어 양식산업의 발전은 중앙 및 지방 정부, 수협과 같은 어민 조합 및 연근해 수산업 종사자들이 출연한 기금을 통해 이루어지고 있음을 지난 8월 북해도의 양식산업을 시찰했을 때 확인할 수 있었던 사실이다. 이제 우리나라도 국민소득 1만불 시대를 넘어 2만불 시대를 열기 위한 청사진을 그릴 만큼 모든 경제의 규모가 확대되었을 뿐 아니라 질적으로 고도화되었다. 우리에게 필요한 것은 성숙된 산업사회에 걸맞는 각 산업 주체들의 의식이다. 한국의 양식산업도 자조 정신을 갖추어 생산성 향상에 초점을 맞춘 양식기술의 개발, 환경 보전을 고려한 양식장 관리 및 소비를 확대하기 위한 유통시스템의 선진화에 스스로 투자를 해야 할 시기에 와 있다.치가 완전히 익은 15일 후에는 무첨가 김치, 0.1%, 0.2% 및 0.3% 고분자 키토산 김치의 젖산균 수는 5.4X107 cfu/g, 3.3X107 cfu/g, 8.6X106 cfu/g 및 2.6X106 cfu/g로 나타났다. 5. 발효가 진행 중에 대장균 군 수가 시간과 더불어 대장균군 수가 모든 구에 있어서 6일까지는 서서히 증가하다가 그 후부터는 대장균 군 수가 감소하였다. 즉, 발효초기에는 모든 구가 2.0X104∼4.0X105 cfu/g이었고, 6일 경에는 8.9X104∼4.5X105 cfu/g로 약간 증가하였으며 15일후에는 키토산 무첨가 김치가 2.0X

This study is to analyze Gwangju's trade structures with China, Japan and the United Sates, and to contribute, through clarification of product competitiveness, to minimizing free-trade-induced costs as well as maximizing profits from free trade. To obtain this study purpose, two export competitiveness indicators are used; they are Trade Specialization Index (TSI) and Grubel & Lloyd(GL) Index. Intra-industry trade is examined to see if there exists a technological gap between nations. Intra-industry trade is divided into two; Low Quality Vertical Intra-Industry Trade (LQVIIT) and High Quality Vertical Intra-Industry Trade (HQVIIT). Gwangju's trade with China is HQVIIT; Gwangju exports high-quality and high-priced items to China, and imports low-quality and low-priced ones. On the other hand, Gwangu's trade with Japan is mainly LQVIIT; Gwangju exports low-quality and low-priced processed stuffs to Japan, and imports high-quality and high-priced ones from Japan. While Korea-US is mainly of both high-quality and low-quality Vertical Intra-Industry Trade; Gwangju exports low-quality and low-priced items as well as high-quality and high-priced items to the USA. Based on the analysis result, export marketing strategies are presented as follows: the transition to high value-added export system, the local entry networking, government support for trade exhibition, offer of special program on local small businesses.

The purpose of this study was to compare inter-regional accident modes using the National Hospital Discharge Patient Injury Survey. In order to determine economic status of each region, 234 cities and counties were categorized as 5 groups according to their financial self-reliance ratio. The main results are as follows. First, transport accidents had increased by the age group of 25 to 44 but decreased thereafter. Second, the frequency of car accidents was the highest among several types of transport accidents. Most common site of transport accidents was roads and highways. Third, there was significant difference in the modes of transport accident among regions. Fourth, emergency admission rate was quite different according to regional groups but it was no significant difference by economic status. Lastly, there was significant difference in injury patterns by region groups. In regions which were high economic status, there were relatively less serious injury patterns such as sprain, strain, dislocation while regions which were in low economic status had experienced serious injury including fracture, stab wound, and open fracture. We could find the difference in accident modes by regional economic status. Therefore, health authority should consider different accident prevention strategies by regional groups.

Korean traditional practice that gets a gravesite for burial and reckless grave establishment not only obstructs systematic national land management and reasonable urban development, but also causes a serious factor which has a harmful effect on natural environment and residential space in reality that our country is limited in area and national and social bases for use and establishment of graves are still inadequite. Though government and local governments have tried to cope with these problems by enacting legislation on funeral and others and so forth, they still have a variety of problems due to the shortage of grave management systems and information of accumulated individual graves. This study describes about the development of a GIS-based grave management system for making administrative management for individual cemeteries the prime object. As a result of application to a pilot area, the system developed in this study was able to be applied for supporting the time-limited burial system and managing cemeteries for those who left no relatives behind by constructing the database with grave-related position/attribute information which are collected by administrative system or direct survey. In addition, it is expected that this system will be utilized as a systematic management method that can be handed down the present or the future descendants under the tradition of the family-oriented funeral culture.

The purpose of this study is to find out the operational status of regionally focused home rearing support projects. The existing rearing support policies on the government level are assessed as not capable of reflecting various requirements of each family and not practically supportive. Therefore, to overcome these limitations, this study focused on the operation case of Jinju City's child rearing comprehensive support center, which is operating various rearing support projects on the regional community level. To find out the operation status of regionally focused home rearing, this study performed literature collection related to home rearing support projects in JinjuCity, interviewed the persons in charge as well as participants, and observation by actual participation. The results show the characteristics of realization of publicity in child rearing focused on municipalities, operation of projects with consistent directionality, and creation of networks reflecting various characteristics and requirements of the community, through the operation status of regionally focused home rearing. This study will be a useful reference for the settlement and operation of the child rearing comprehensive support center, which is entering into a new transition period, and is meaningful as this study provides the basic material for the desirable direction to be pursued by the regionally focused home rearing support projects.

Recently, the incidence of flooding in Korea has decreased by the measures by central and local governments, however the scale of damage is increasing due to the improvement of living standard. One of the causes of such flood damage is natural causes such as rainfall exceeding the planned frequency of flood control under climate change. In addition, there are artificial causes such as encroachment of river spaces and management problems in upstream basins without consideration of downstream damage potential by regional development flood. In this study, in order to reduce the inundation damage caused by flooding of river, the situation at the time of inundation damage was reproduced by the detailed topographic data and 2D numerical model. Therefore, the effect of preparing various disaster prevention measures for the lowland was simulated in advance so that quantitative evaluation could be achieved. The target area is Taehwa river basin, where flooding was caused by the flooding of river waters caused by typhoon Chaba in October 2016. As a result of rainfall-discharge and two-dimensional analysis, the simulation results agree with the observed in terms of flood depth, flood arrival time and flooded area. This study examined the applicability of hydraulic analysis on river using two-dimensional inundation model, by applying detailed topographic data and it is expected to contribute to establish of disaster prevention measures.

To reduce the effects of greenhouse gas (GHG) emissions, the government has announced the special platform of technologies as parts of an effort to minimize global climate change, and the government distributed biodiesel since 2006 as the further efforts. Although there are some debates about some quality specifications and unbalanced of source (44% from palm oil), more than 400kton/year of biodiesel was produced in 2013. Moreover the amounts will be increased when the RFS is activated. To solve the unbalanced situation and to achieve the diversity of feeds, it is essential that many researches should be considered. Especially, free and bond glycerines are one of the important properties seriously affected to the combustion system in vehicle & cold properties. Previous method (KS M 2412) couldn't cover the biodiesel derived from lauric oil($C_{12:0}$) such as PKO (Palm Kernel Oil), Coconut oil because those compositions are lighter than other conventional biodiesel sources. In this study, we review the existed method and figure out the factors should improve to analysis the glycerine from PKO and Coconut oil biodiesel. Modifying the analysis conditions to enhance the resolution and change the internal standards to avoid the overlapped- peaks between Capric acid ME ($C_{10:0}$) and standard#1(1,2,4-butantriol). From this revised method, we could solve the restrictions of previous methods. And check the possibility of new method to analyze the glycerine in biodiesel regardless of sources.
