As the economy and the social develope, the human desire has advanced from physical needs toward social needs. In short, unlike the past when the management might well simply compel, workers to product and pay Wages, the modern management has to come to set up institutions and facilities for workers. As a result the establishment of Welfare system become necessary, and this system has the purpose of accommodating the promotion of the living standard and Welfare of workers and approciating their economic, social, cultural position. In previous days, Welfare System was viewed as what the enterprise simply carries out the social responsibility, but nowadays. The active participation of enterprise has come to be required of late, the issue of Welfare problem is frequently being discussed in our country as well. They enterprise the Welfare System for workers should be improved in pace with the qualitative growth of economy, and point out that there are increasing claims for promotion of Welfare among Labor organization and workers. In this paper, I investigated the current state of implementing Welfare System and the degreed of the rate of Welfare expenditure to gloss Sabo and so on in D industrial Corporation in our country, analyzing the problematic point of it, then I tried to suggest to direction the which Welfare System promoted.

본 논문의 목적은 선박 연료유 가격의 결정요인을 분석하려는데 있다. 선박연료유는 전 세계적으로 년간 약 1억 5천만 톤 정도 소요되고 있으며 이는 1999년 10월 국제유가를 기준으로 하면 약 250억불 정도로 추산된다. 두차례에 걸친 국제원유가 파동 후 선박 연료유가는 시시각각 변동폭이 크고 불안정하여 거래 관련 당사자들에게 이에 따른 적절한 위험관리와 대책이 절실히 요구되는 상황이며, 한편, 이는 적극적인 의미에서는 새로운 이윤 창출의 기회를 제공해 주기도 한다. 본 연구는 이를 위하여 선박 연료유에 관한 시장과 경제성, 기술적 측면들을 문헌 자료를 이용하여 연구하였으며 이와 함께 통계 분석을 통한 실증적 연구를 하였다. 기술적 연구를 통하여 연구 모형과 가설을 설정하였고 여기에서 설정된 주요 가격 결정 요소에 대하여 상관성 분석과 회귀추정방식을 활용하여 과거 4년간 (1996-1999)의 시계열 자료를 통계 분석하였다. 상기 통계분석 결과를 요약해보면 다음과 같다. 첫째, 선박 연료유가는 본 연구에서 설정한 3가지 요인에 의하여 90%가 설명되는데 이들은 세계 원유공급량, 국제 원유가, 세계 교역량이다. 둘째, 세계 원유공급량의 회귀계수는 5% 미만의 유의수준에서 부(-)의 값을 보였고 세계 원유가의 회귀계수 역시 5% 미만의 유의수준에서 정(+)의 값을 보였다. 세계 무역량의 회귀계수는 정(+)의 값을 보였으나 유의 수준이 10% 미만으로 높게 나타났다. 즉 연료유 공급의 대리변수인 세계 원유공급량은 연료유가에 반비례하고 주요 비용 요인인 세계 원유가는 원료유가에 비례함을 보여준다. 그러나 세계 물동량의 대리변수인 세계 교역량은 그다지 큰 상관관계를 보여주지 못했다. 셋째, 각 결정요인들에 대한 가격 변동 정도(탄성치)를 보면 원유공급량과 원유가에 대한 탄성치는 각각 -1.689와 0.712로 높은 반면 세계 교역액에 대한 탄성치는 0.369로 비탄력적인 것으로 나타났다. 이상의 연구 결과들을 볼 때 다음과 같은 결론을 얻을 수 있다. 첫째, 선박 연료유 시장은 완전 경쟁적 요소와 공급자 중심의 과점적 성격을 동시에 가지면서 가격은 시장 공급 상황과 마크업(Mark-Up)에 따른 비용 요인에 의해 결정되어지고 있다. 둘째, 세계 시장에서는 선박 연료유 가격은 세계 공급량 변화에 가장 민감하게 반응하고 있으며, 비용 측면에서 국제 원유가 변동에도 크게 영향을 받고 있다. The purpose of this study is to analyze the determinants of price of international marine fuel oil(herein after marine fuel). About US$150 million metric tons of marine fuel equivalent to about US$25 billion are estimated to be traded in the world annually. The price of marine fuel has become so volatile after "Oil Crises" that it requires the transaction parties involved to improve ability to manage the price risk, and it creates a new opportunity to make a profit from fluctuation of the price. It surveys markets, economics and technical aspects of marine fuel to find out the determinants of the price. A model of study and hypothesis are established based on the survey by literature on the subject. After dominating factors have been found, the determinants were analyzed by corellation analysis and OLS regression method on time-series data for four (4) years 1996-1999. A result from the statistical analysis on correlation between the determinants and price of marine fuel is summarized as follows. (1) Price of international marine fuel is explained 90% by three(3) independent variables. Those are world crude oil price, world crude oil supply and world trade volume. (2) Co-efficient of world crude oil price shows positive(+) in less than 5% significance. Co-efficient of world crude oil supply shows negative(-) in less than 5% significance. Co-efficient of world trade volume shows positive, however, in high significance of 10%. Therefore price of marine fuel is inversely proportional to world crude oil supply, and is proportionate to world crude oil price. World trade volume as a proxy variable for demand of marine fuel is proportional to the price, even though it has low statistical significance. (3) Price elasticity to world crude oil price and world crude supply represents + 0.712 and -1.689 respectively, which seems fairly and very highly sensitive respectively. Price elasticity to world trade volume shows + 0.369, which is rather unsensitive. The results from the analysis lead to the conclusion : Firstly, in the marine fuel oil market having both element of perfect competition and that of olygopoly, the price is determined by supply side market circumstance and cost factor by mark-up. Secondly, the price of marine fuel oil reacts most sensitively to world crude oil supply, and fairly sensitively to crude oil price in terms of production cost. However, demand of marine fuel oil does not influence the price significantly.

金太植 淸州大學校 2000 국내박사

본 논문에서는 계층적 탐색 기법을 이용한 동적 배경에서의 이동물체 추적 알고리즘을 제안하였다. 제안한 알고리즘은 초기모델 생성단계와 이동물체 추적 단계로 구성되어 있다. 초기모델 생성단계는 영상에서 움직임이 있는 영역만을 분할하는 단계와 초기 정합모델 생성 단계로 구성되어 있다. 배경영상과 처음 이동물체가 진입하는 영상사이에 차영상을 추출하고, 차영상을 이진영상으로 변환한다. 이진 영상을 가지고 모폴로지 제거연산을 취하여 잡음을 제거하고, 클러스터링 기법을 이용하여 이동물체에 대한 영역을 분할한다. 초기 이동물체 진입 영상의 윤곽선 영상을 윤과선 기준 영상이라 하고, 이 윤곽선 기준영상과 이동물체에 대한 분할 영사을 가지고 논리적 AND 연산을 수행하여 정합 모델을 생성하였다 이동물체 추적 단계에서는 이동물체의 탐색시간을 줄이고 추적속도를 빠르게 하기 위해 현재영상에 대한 윤곽선 영상을 구하고, 윤곽선 영상을 1/4로 축소(Decomposition)한다. 또한, 정합모델을 1/4로 축소시켜 탐색모델을 생성시킨 후 탐색모델과 1/4로 축소된 현재 영상을 정합을 하였다. 정합된 영상에서 4근방2-D Logarithmic탐색으로 이동 물체의 면적중심 좌표를 대략적으로 탐색해 낸다. 대략적으로 탐색된 이동물체의 면적중심 좌표를 중심으로 정합모델과 현재 윤곽선 영상을 재 정합하여, 2-D Logarithmic탐색으로 정확한 이동물체의 면적 중심 좌표를 추출한다. 이전프레임에 비해 이동 거리가 큰 경우에도 안정적으로 추적할 수 있었다. 그리고, 카메라의 흔들림과 추적물체의 3차원 운동으로 인한 형태 변화에도 전체 프레임에서 효과적으로 추적을 할 수 있었고, 이동물체의 정확한 위치를 검출하여 추적시간을 단축할 수 있었다. 정합모델과 윤곽선 영상에 사이에 이동물체의 유사도 판정은 Partial Hausdorff 거리를 이용하여 평가하였다. 현재 영상에서 이동물체가 검출되면 이동물체의 움직임에 따른 형태 변화에 적응할 수 있도록 이동물체의 위치, 크기, 속도, 이동방향 등과 같은 누적정보를 이용하여 새로운 모델을 갱신하고, 이동방향을 예측하여 이동물체 추적을 수행하였다. 제안한 알고리즘의 타당성 검토를 위해 도로에서 주행하는 차량을 대상으로 이동물체 검출 및 추적 실험을 한 결과 정합회수는 평균 28.21회이고, 프레임 당 정합시간은 평균 53.21ms로 제안한 알고리즘의 우수성을 입증하였다. 추적위치와 실제위치를 비교하여 그 평균 자승오차를 계산한 결과 E=1.148임을 알 수 있었다. 차량의 크기, 색상 및 형태가 다른 경우 도로의 색과 차이가 있는 차량들은 98.66%의 추적 성능을 나타냈으며, 검정 색 또는 적색 등과 같은 차량은 흑백 영상에서 도로의 색과 유사하여 배경의 영향을 많이 받으므로 95.33%이었고, 전체 평균은 97%의 우수한 추적 성능을 나타내었다. This paper proposed a moving object tracking algorithm by using hierarchical search method in dynamic scenes. Proposed algorithm is based on two main steps: generation step of initial model from the difference picture, and tracking step of moving object under the time-varying scenes. In the generation stage of initial model, segmentation procedure which is only segmented a motion region and generation procedure of matching model are involved. These procedures are as follows. The first step in segmenting the motion region is to extract the difference picture(DP) between background image and motion image. After transforming binary image, noise is removed by using morphology operation, and moved region is segmented based on clustering scheme. Matching model is generated by performing the logical AND operation using these reference and segmented images. In the tracking moving object stage, in order to reduce search time as well as to speed tracking process edge image is decomposed by quarter size. Based on 4-neighbor 2-dimensional(2D) logarithmic search method, center of area coordinate of the moving object is calculated. With these procedure, tracking process is not only stable in the case of large distance with respect to the previous frame but also reliable in that of shape variation due to the 3-dimensional(3D) motion and camera sway, and consequently, owing to the correct position of moving object, tracking time is relatively reduced. Partial Hausdorff distance is also utilized as a estimation function to determine the similarity between model and moving object. Successive model upgrade is carried out on the basis of cumulative informations such parameter as velocity, location, scaling of moving object. In order to testify the performance of proposed method, the extraction and tracking performance have tested using some kinds of moving car in dynamic scenes. Experimental results showed that the proposed algorithm provides higher performance. Namely, matching order is 28.21 times, and considering the processing time per frame, it is 53.21ms/frame. Computation result between the tracking position and that of currently real with respect to the root-mean-square(rms) is 1.148. In the occasion of difference vehicle in terms of size, color and shape, tracking performance is 98.66%. In such case as background-dependence due to the analogy to road is 95.33%, and total average is 97%.

해양유래 방선균에서의 신물질 탐색

김태식 漢陽大學校 大學院 2001 국내석사

해양유래 미생물들은 신물질 발굴의 새로운 원천으로 떠오르고 있다. 최근 특이 구조와 생리활성을 가진 많은 대사물질들이 다양한 해양 동식물과 퇴적층에서 채집된 박테리아와 진균등에서 분리되고 있다. 해양유래의 방선균에서 새로운 구조와 생리활성을 갖는 물질의 탐색과정 중 통영만의 유기물 퇴적층에서 Genus Streptomyces를 분리해 M2750이라 명명하였다. M2750의 culture broth에서 추출한 유기물질들은 Candida albicans에 강한 항진균 활성을 나타내었다. 이 논문에서 3가지의 새로운 lactone-containing 대사물질과 이미 알려진 물질인 (-)-blastmycinolactol의 구조결정을 하였다. 이 물질들은 모두 3-hydroxy--blastmycinolactol으로서 구조적으로는 항진균제인 antimycin 계열의 물질과 유사하다. M2750은 3 L Fernbach flask에서 10일간 배양하였다. 배양액을 membrane filter로 거른 후 HP 20 adsorption chromatography를 행하였다. MeOH와 acetone으로 용출한 분획들을 혼합하여 반복적인 solvent/solvent partition에 의해 중간정도의 극성을 가진 분획들을 회수하여 LH 20 gel filtration chromatography를 한 후 이것을 다시 reversed-phase HPLC를 행하여 MKN-004A~D의 4가지 물질들을 분리하였다. 그러나 최종 분리된 물질들은 항진균 활성이 실활된 물질로서 얻어졌다. 이들 중 MKN-004A는 (-)-blastmycinolactol로서 antimycin-producing Streptomyces spp의 중간 대사물질로 알려져 있다. 그러나 antimycin이라 확신할 수 있는 물질들은 검색되지 않았다. 이러한 결과로 유추할 수 있는 것은 육상에서 antimycin을 생산하던 방선균이 연안의 환경으로 서식장소를 옮기는 과정에서 육지와는 다른 해양환경에 적응하고자 이차대사 산물생성 메커니즘을 바꾸었기 때문이 아닌가 추측된다. 이차대사는 해당 생물의 직접적인 생존에 관계되는 것이 아니기 때문에 모든 생물들에서 유사하게 나타나는 단백질이나 핵산들과는 달리 조그마한 환경의 변화에도 그 나타나는 추이는 극히 다를 수가 있다. 이러한 이유로 원래는 antimycin을 생산하던 방선균이 해양이라는 새로운 환경에 적응하면서 기존의 antimycin class의 물질들과는 좀 다른 물질들을 생산한 것으로 추정된다. Microorganisms derived from marine environments are widely recognized as an emerging source of novel natural products. In recent years, numerous metabolites possessing uncommon structures and potent bioactivity have been isolated from strains of bacteria and fungi collected from diverse marine environments, such as animals, plants, and sediments. During the course of our search for biologically active substances from marine-derived actinomycetes, we isolated a strain of the genus Streptomyces from shallow-water sediment rich with decaying organic materials collected from Tongyoung Bay, Korea. The organic extract from the culture broth of this strain exhibited significant antifungal activity (in paper disk method, inhibition zone 19 mm at the concentration of 50 μg/disk) against Candida albicans. We describe herein the structure determination of three new lactone-containing metabolites along with the previously reported (-)-blastmycinolactol. These four compounds, MKN-004A-D, are 3-hydroxy-γ-butyrolactones, structurally related to the antifungal agents of the antimycin class. The strain M2750 was fermented in a 3 L Fernbach flask for 10 days. The culture broth was filtered through a membrane and subjected to HP 20 adsorption chromatography. The fractions eluted with MeOH and acetone were combined and repeatedly solvent/solvent partitioned. The moderately polar fractions were separated by LH 20 gel filtration chromatography followed by reversed-phase HPLC to yield MKN-004A-D as pure metabolites. Both the crude extract of M2750 and LH 20 chromatographic fractions containing MKN-004A-D showed remarkable antifungal activity against C. albicans. However, the same measurement using pure metabolites revealed that the bioactivity was not attributable to butyrolactones. A plausible explanation is the presence of antimycins or related antifungal agents since literature studies revealed that (-)-blastmycinolactol was a hydration product of the potent antifungal agent antimycin A3 (=blastmycin) and both metabolites frequently occurred together. However, careful examination of the 1H NMR spectra did not indicate these metabolites to be in the crude extract or its chromatographic fractions. Furthermore, production of several novel 3-hydroxy-γ-butyrolactones distinguished the strain M2750 from the previously described antimycin-producing Streptomyces spp. and suggested the presence of another class of antifungal substances which remained to be identified.

Port redevelopment in 2009, a year in Korea as the first recorded case of Busan bukhang redevelopment marks the full launch. Total of 8.4 trillion won is estimated to have spent bukhang Busan Port Redevelopment Project with the city behind the new districts to develop and present a new model in that it harbors a big turning point for policy is considered to be the case. Past the export through the port policy of rapid economic growth as the infrastructure to support the timely expansion of port facilities has been focused on. To 1970~80's goes through the industrialization process which is sudden and the income and manufactured goods export of raw materials putting first are actualized and etc. The expansion of the port facility introduce the cargo work machine and inner wall with putting first becomes accomplished equipped the features of the harbor where is modern. Starting in the 1990s, on the process of the larger size of the cargo ship progress and containers of the freight, harbor policy where the concept of the goods is introduced in the harbor of past simple freight processing function and there was big change. In the process, Busan New Port and Gwangyang ports and a dedicated container handling facilities and the development of the site of New Port rear being developed begin with was whether the existing port that functions as a traditional pier continues to be weakened to only result was not. These sudden changes in aging port logistics environment through redevelopment and new value creation is a need. Because of the national income comes to be high recently and the augmentation of leisure activity, the harbor space which has become idleness under redeveloping boil is a situation where the demand is increasing with the environment which is comfortable. Port the planning and redevelopment projects in the following three key steps to realize a vision that is targeted. First, the old harbor Waterfront where redevelopes as social property the individual or the group which is various, the group easily will approach and will can own jointly and must be a space where is opened. Second, the harbor and surrounding area, combined with marine-oriented exchange by the redevelopment of the harbor and the city chapter of the sustainable development and coexistence should be possible. Third, create jobs and increase the value of real estate in the area by attracting new business and tourism resources by making contributions to local economic development should be updated. Above the harbor redevelopment value of the priority is on creating citizens of the rest area. The birth of the new harbor redevelopment Waterfrontsms caught sea parks, amusement parks, resort complex, recreation facilities and locations to be utilized by the citizens of the shelter, income growth, increased tourism and leisure, depending on the population is expected to be a great help in absorption.

北韓 核問題와 韓國의 對應方案에 관한 硏究 : 한국형 전략무기 확보를 중심으로

金泰湜 한성대학교 2010 국내석사

Running contrary to the opposition casted from Korean and the international community, North Korea forcefully pushed forward with their second nuclear testing at 2009, following the previous 2006 testing. Despite the opposition from all dimensions, the motive to move forward with the testing was deemed as an act to sustain the dictatorial regime led by Kim Jong Il, and attempt to achieve rapid unification under North Korean terms through surprise offensives. The challenge lies, however, on the fact that chances for success through collaborative dialogue are considered low at this time. As it was exhibited in the Six Party Dialogues from the past four years since the 2006 North Korean nuclear testing, the Dialogue itself proved ineffective due to the differences shown by each member, where even the resolutions extracted from long endeavors were interpreted differently by each participating countries. Although South Korea must exert efforts to resolve the North Korean nuclear crisis through peaceful means with the international community, South Korea must also contemplate a responsive course of action to prepare against a North Korean nuclear provocation caused by misperception or misjudgment. Also, it is considered as a principle for the military to gear up full out readiness posture against such provocative threats. Therefore, a practical preparation to such scenario is the acquisition of a South Korean style strategic weapon system. A South Korean style strategic weapon system is considered a weapon designed for massive destruction but basically deters or response to nuclear threats. Therefore, the possession itself is regarded as a strong political message to deter any aggressive intent displayed by its adversaries. Even in times of war, such system will dissuade the war fighting motive and capability of the adversary through the proper use of the system that calls in early victory or the cessation of war itself. However, the reason for acquiring such capabilities must be convincing and persuasive through cost benefit analysis. The acquisition of a strategic weapon system must not only accompany a synergetic effect to the national wealth, but also guarantee strategic superiority over its enemy. The system must also bring regional stability in Northeast Asia by balancing with its neighboring countries such as China and Japan. Although the South Korean style Strategic Weapon system is considered non-nuclear, in general it must comply with international norms and regulations. At first, it must consider the implications to the relationship with the U.S. and adjacent countries. In order to alleviate the concerns of another regional arms race, South Korea must show diplomatic efforts to ease such concern. Domestically, the government must convince the public on the need to acquire such system as well as to show efforts on other sector such as social welfare that the budget is being equally allocated to other primary areas for social need.
