The forming process of poverty region in Taegu and the feature of its spatial distribution which are reviewed hitherto can be summarized like this. 1) In the froming porcess of poverty region in Taegu, during the soverignty of Japanese Empire petty farmers became tenantry by the colonial agricultural policy of Japanes Empire and some of those came into the city and g\became urban poor class. They generally lived in poor houses or dugouts in the city, and 6.6$\circ$ of poor house and dugouts of the whole country were in Taegu and 4.9$\circ of the popolatio in Taegu resided there. During the period of disorder, because of the historic accidents, such as the restoration of independence and Korean War, the returnees from aboad and refugees converged into the big city so that those who need the country's relief stood out as new poor class. They generally made their dwellings with tents and straw-bags on vacant grounds in suburbs living form hand to mouth and shaped the poor houses area, so-clalled "Liberated Village". During the developing period, the number of those who need aid gradually decreased, but the problem of poor people by the city-concentration of the poeple who shifted from agricultrual jobs by economic development came to the front. They mostly lived in squatter area forming large poor class area, and generally located near the center of Taegu consisiting of West. South. East Ward. 2) Reviewing the the feature of spatial distribution, the proportion of poor class are highest within 1~2km from the center of the city and also high within 2~3km form the center and suburbs. The poor class area in the center of the city are mostly cleared and removed area and in suburbs by the construction of permanently leased, and leased apartments large grouped poor class areas are forming. In Taegu, 16 low-income class group residence areas and residential environement improving areas are dispersed so that they came under the so-called poor class area. But by the improvement of dewelling environment and living the poor people who lived in groups dispersed or bettered their living for themselves, so the poverty area is greatly chaning into average-levelled residence area, and on the other hand, large poor people's apartment complexes are being constructed in suburbs. 3) Up to now, the distribution of poverty area could be limited its scale to generally the area within 1~3km because the poverty region which had been in suburbs relatively came near the center of the city by the rapid urbanization and poor people preferred that area because of the living convenience facilities as well as the transportation facilities and job-hunting being near the center of the city. But now poor people's apartment complex is being constructed regardless of their zone of job sites, so the low proportion of occupation is pointed as a new problem.

This study was carried out to analyze the food intake and associated factors of the urban poor elderly by comparing poor district, Unbong rental apartment in Bansong 2 dong with other areas in Pusan. 135 elderlies(men 36, women 99) in Unbong rental apartment, 136 elderlies(men 45, women 91) in the other areas were investigated during the period of March to August in 1994. The assumption that the study area represented poor district was satisfied because the age and sex distribution was not significantly different, and the income of the study area was significantly lower than that of the control area. The variables of hospitalized in previous 12 month, gastrointestinal problem, alcohol drinking, cigarette smoking did not differ significantly. But the variables of chronic disease, take medicine, perceived health, vitamin supplement differed significantly between two groups. Therefore some factors associated with health state in the study area are worse than those of the control area. At most of all variables, nutrients intake of the study area did not reach the recommended dietary allowances(RDA) for Koreans, and that nutrient intakes of the study area were significantly lower than those of the control area. The hypothesis of this study that nutrient status depends on economical status was proved. As for the score of nutritional knowledge, the study area was significantly lower than the control area. But as for the score of nutritional behavior, two areas were not significantly different. The latter is counter result of our hypothesis, owing to the effect of the confounding factors including education etc. As for the correlation of variables, not only economic status and educational level, but the score of nutritional knowledge effects strongly on nutrient status in the study area, the poor district. Therefore, adequate nutritional education to the elderly in e poor district should be considered.

Citrullinemia type1 is an autosomal recessive disorder of the urea cycle characterized by neonatal or late onset of hyperammonemia caused by a deficiency of the enzyme argininosuccinate synthetase (ASS). An ASS1 deficiency demonstrates fatal clinical manifestations that are characterized by the neonatal metabolic coma and early death when untreated. It causes a broad spectrum of effects, ranging from a mild disorder to a severe mental retardation, epilepsy, neurologic deficits. An acute neonatal form is the most common. Infants are normal at birth followed by an acute illness characterized by vomiting, lethargy, seizures and coma. These medical problems are life-threatening in many cases. A later onset form is less frequent and may be milder than the neonatal form. This later-onset form is associated with severe headaches, visual dysfunction, motor dysfunction, and lack of energy. Citrullinemia type1 is caused by mutations in the ASS1 gene located on chromosome 9q34.1 that encodes argininosuccinate synthetase, the third enzyme of the urea cycle catalyzing the formation of argininosuccinic acid from citrulline and aspartic acid. The enzyme is distributed in tissues including liver and fibroblasts. This mutation leads to hyperammonemia, arginine deficiency and elevated citrulline level. In the urea cycle, argininosuccinate synthetase catalyses the conversion of citrulline and aspartate to argininosuccinate.. Here, we describe a female newborn patient with lethargy, rigidity and hyperammonemia who was diagnosed as citrullinemia type1 with a c.[421-2A>G], c.[1128-6_1188dup] mutation.

This paper aims at examining the indices and their weights for the evaluation of local government to allocate reconstruction charge and reviewing the availability of them simulating local governments' evaluation. There has been no specific evaluation criteria existed, while central government has to allocate the reconstruction charge to local governments by the provision 3 of Restitution of Housing Reconstruction Gains Act. The results as follows : According to a survey on evaluation indices weight and AHP analysis, the weight of 'the housing welfare improve effort' is the highest with 25.1% among 5 upper-classification indices. Following this, each weight of 'housing welfare conditions(22.7%)', 'housing SOC establishment(22.5%)', 'the achievement and planning on reconstruction charge use(15.8%)', and 'housing sector achievement such as Bogeumjari(13.9%)' are ranked. Meanwhile, Among 16 lower-classification indices, 'the rate of minimum housing standard households(11.5%)', 'public rental housing supply(8.9%)', 'reconstruction charge use achievement(8.3%)', 'reconstruction charge use planning submit(7.5%)', and 'rate of water and sewage(6.3%)' hold high rank. The analysis results show the weight of 'housing sector achievement such as Bogeumjari' on the existing provisions should be decreased(30%${\rightarrow}$13.9%) as others' weight has to be slightly increased. According to the result of the simulation, Jeonbuk, Gyeongbuk, Jeonnam, Jeju, Gyeonggi received higher scores in the comprehensive evaluation, while Daejeon, Seoul, Incheon, Daegu and Gwangju, where the housing conditions are relatively good, received lower scores. These results of the analysis correspond with the direction of reconstruction charges allocation and indicate that the evaluation criteria used in this simulation is acceptable.

For two agricultural reservoirs that are rented for fishing spots, benthic nutrient fluxes experiment were performed two times with two sediments from fishing-effective zone and one sediment from fishing-ineffective zone using laboratory core incubation in oxic and anoxic conditions. During benthic nutrient fluxes experiment, the changes in DO, EC, pH, and ORP in the supernatant were not significantly different between fishing-effective zone and fishing-ineffective zone, and were similar to the sediment-hypolimnetic diffused boundary layer in agricultural reservoir. Except for $NO_3{^-}-N$, more benthic nutrient fluxes of $NH_4{^+}-N$, T-P, and $PO{_4}^{3-}-P$ from sediment to hypolimnetic was measured in anoxic than in oxic conditions (p<0.05). As the DO concentration in hypolimnetic decreases, the microorganism-mediated ammonification is promoted, the nitrification is suppressed, and finally the $NH_4{^+}-N$ diffuses out from sediment to hypolimnetic. Also, the diffusion of T-P and $PO{_4}^{3-}-P$ from sediments to hypolimnetic is accelerated through the dissociation of the phosphorus bound to both organic matters and metal hydroxides. The difference in the benthic nutrient diffusive fluxes between fishing-effective zone and fishing-ineffective zone was not statistically significant (p>0.05). Therefore, it was found that fishing activities did not increase the benthic nutrient diffusive fluxes to a statistically significant level. Due to the short fishing activities of 10 years and the rate-limited diffusion of the laboratory core incubation, the contribution of fishing activities on sediment pollution is estimated to be low. No significant correlation was found between the total amount of nutrients in sediment and the benthic nutrient diffusive fluxes in both aerobic and anaerobic conditions. Therefore, nutrients input from various nonpoint sources of watersheds are considered to be a more dominant factor rather than fishing activities in water quality deterioration, and both aeration and water circulation in hypolimnetic were required to suppress the anoxic environment in agricultural reservoirs.

IMPACT Silver 주식회사는 Zacualpan 프로젝트의 Royal Mines(이하 로얄 광산)을 인수했다. $124.5\;km^2$에 해당하는 지역의 소유권은 두 개의 멕시코 사기업으로부터 가행중인 광산의 채굴권 구입과 운영 중인 기반시설의 임대를 조건으로 한다. 프로젝트 지역은 멕시코시티로부터 남서방향으로 100 km와 Taxco Silver 광산으로부터 북서방향으로 25 km 떨어진 지점에 위치한다. 기반시설은 비포장 도로, 충분한 전력과 물의 공급 및 숙련공들을 갖추어 우수한 평가를 받고 있다. 소유권은 멕시코인의 개인소유 하에서 무한한 매장량 혹은 자원량을 갖고 운영된 채광과 가공시설을 인수하는 것이다. 소유권 지역을 대상으로 한 IMPACT Silver사의 주 탐사목적은 이미 알려진 광화대의 확장을 위한 잠재성 평가와 다른 지역에서 신규 광상의 유망지역을 발견하는 것이다. Zacualpan 프로젝트의 로얄 광산은 남동 Guerrero terrane의 북부에 위치한다. Teloloapan subterrane은 주로 저변성 녹색편암상으로 구성된 쥬라기 후기에서 백악기 초기의 화산성 퇴적층으로 구성된다. 대부분의 유망지역은 Lower Villa de Ayala층의 중성 내지 염기성 화산성 쇄설암을 모암으로 한다. 다상의 변성작용은 지역 전반에 걸쳐 나타나고, Zacualpan 광산지역에서 수반되는 광화작용을 규제한다. Zacualpan 광산지역은 Sierra Madre del Sur로 알려진 유망 광화대에 해당한다. 이 지역은 화산성 괴상 황화광상과 천열수 맥상광상이 우세하다. 대부분의 천열수 광화작용은 3.2-3.8억 년 전 마그마의 생성이 활발한 판구조 체제 동안 발생하였다. 역사적으로 가장 주요한 지역은 Lipton Vein이다. 현재 Zacualpan 지구에서 채광량은 은 200-500 g/t 정도로 보고되고 있다. 일부 지역은 고품위 은 광화작용(은 1,000 g/t 이상)을 수반하고 있으며, 이는 탐사의 주 타겟이 되고 있다. Zacualpan에서 은 광화작용은 은이 부화된 중유황 천열수 맥상광상으로 상당히 유명하다. Fresnillo, Pachuca 및 Taxco 광산을 포함한 멕시코 소유의 대규모의 잘 알려진 광산들이 이에 해당한다. 이러한 광산들은 부산물로서 금, 아연, 연이 생산된다. 이러한 광상들은 맥상과 각력상 및 산점상 또는 망상세맥의 형태로 산출된다. 광화작용은 석영과 탄산염 맥 내에 주로 황철석과 다양한 섬아연석, 방연석, 은 혹은 금 광물들을 수반한다. 경제성을 갖는 광화작용의 수직적인 연장은 평균적으로 대략 300 m이고, 멕시코 중부에 위치한 Fresnillo의 광화작용은 100 m에서 960 m의 연장을 갖는 것으로 알려져 있다. 아주 오랫동안 Zacualpan에서 광산관계자의 관측과 IMPACT Silver에서 최근 작업의 결과를 토대로, Zacualpan 광산지역의 탐사모델은 새로운 광상의 탐사를 위한 가이드로서 개발되었다. Zacualpan 광산지역에서 가장 높은 경제성을 갖는 광화작용은 북서와 남북방향의 맥 구조를 따라 수반된다. 이러한 맥 구조들은 종종 이 지역을 가로질러 수 km까지 추적되지만, 경제성을 갖는 광화작용은 맥 구조를 따라서 구조적으로 유리한 지역에서 부광대를 형성한다. 부광대를 형성하기 위한 가장 유리한 구조적 지역은 북서와 남북방향으로 발달한 맥 구조들이 교차하는 지역이다. 지난 30년간 채광된 주요 부광대는 폭이 2-6 m 이고 수평연장은 30-150 m 그리고 수직연장은 230-300 m에 이른다. 가장 높은 생산량을 보이는 부광대는 남북방향의 이차 맥들이 Guadalupe 광산의 Lipton 맥을 가로지르는 지역에서 발달한다. 남동쪽으로 현재 Compadres 광산의 Silver Shoot No. 1으로부터 고품위 은을 생산하는 지역은 북서방향의 San Agustin 맥이 북향의 Cometa Navideno 맥에 의해 절단되는 지역에서 산출한다. 모암은 광화작용을 규제하는 또 다른 중요한 요소이다. 광산지역에서 경제성을 갖는 모든 광화작용은 중성 내지 염기성 화산암 특히 안산암과 관련 모암에 배태된다. 부광대가 셰일 혹은 편암으로 전이되는 지역에서, 맥들은 소규모의 세맥으로 나뉘어 진다. Zacualpan의 전형적인 천열수 광상에서 부광대는 상부로 가면서 은의 함량이 증가하고, 하부로 가면서 연 아연의 함량이 증가하는 수직적 대상을 보인다. 금의 함량 변화는 보다 예측이 어려우나 상당히 중요하다. Zacualpan 광산지역의 탐사모델에 사용된 토양 채취, 정밀지도제작, 트렌치 및 시추탐광은 현재 IMPACT Silver사가 이 지역을 대상으로 한 가장 효율적인 탐사방법으로 입증되었다. Zacualpan 프로젝트의 로얄 광산은 하루 500 톤을 제련하는 기반시설과 수반된 채굴권을 갖는 가행 광산들을 포함한다. 현재 IMPACT Silver사는 두 곳의 타겟 지역에서 정밀지도제작, 토양 및 암석 채취, 12공 총 1866 m의 시추탐광에 의한 사전조사로 구성된 4 단계 탐사를 수행했다. 암석 1,953개, 토양 1,631 개, 389 개의 시추코어 시료가 채집되고 분석되었다. 이러한 작업은 추가탐사를 요구하는 수많은 유망 광화대를 규명했다. Compadres 광산에서 현재 가행중인 지하갱 시료는 레벨 1에서 0.9 m의 폭을 갖는 광체에서 은 680 g/t과 금 0.3 g/t, 레벨 3에서 1.67 m의 폭을 갖는 광체에서 은 12,591 g/t과 금 12.07 g/t의 품위를 갖는 것으로 나타났다. 레벨 1에서 3까지 2-3 m의 폭과 30-40 m 연장으로 채광되었다. 시추탐광은 고품위를 갖는 몇몇의 중첩된 맥을 발견했다. Compadres 광산에서 남동방향으로 200 m지점에 위치한 Soledad 지역에서 5 개의 시추공으로부터 동일 맥 시스템이 발견되었고, 고품위 부광대의 상부로 간주되는 몇몇 중요 지점이 발견되었다. 초기 단계의 탐사는 유망 시추탐광 지역인 중간정도 내지 고품위 유망 광화대를 규명했다.

Recently, the ways in which individual communities own and manage parks have been both discussed and realized in America and England. Some benefits of these asset transfers are that local governments can reduce the financial cost of management as well as improve the service of the parks. In addition, communities can develop these parks as unique assets. Ultimately, this is a new understanding of parks as community commons. This study examines the policy of park asset transfers to communities in England. These transfers, which involve reallocating land and building management and/or ownership from the public sector to a community group, are part of a policy agenda known as "Big Society", which aims to create a "small government" within a "big society". The agenda is pursued by both the English Conservative and Unionist Party governments. Eight case studies of community park asset transfers in England were examined in this study, under three categories-transfer process, partnership among stakeholders, and financial structure-and synthesized along three issues-financial contribution, level of public transparency, and closeness of the relationship between park and community. In some cases, new community groups were created specifically to receive park assets, while in other communities, existing groups became the park trustees. For most parks, community groups raise park maintenance funding through diverse methods; however, these groups are often not entirely financially independent from local government. Thus, many park trustees have already created, or are planning to create, other assets from which parks can benefit. Second, some efforts for public transparency include trusts that are registered as charities, of which their public nature is admitted officially. These trusts resolve important decisions through boards of trustees, in an effort to promote income-generating business while not excluding users. Ultimately, a close relationship between park and community empowers the community to participate in managing and maintaining the park; in turn, the park's capacities are improved. Current struggles include the many limits involved in communities accepting ownership and management of a park, and a lack of local government experience regarding public-private management and maintenance of a public asset. This study, however, details interesting policy implications for Korean community involvement as well as diverse financial methods to facilitate park management.

Transportation enterprises should maintain constant and qualitative operation. Thus, in short period, transportation enterprises don't change supply in accordance with demand. In the result, transportation enterprises don't reduce operation in spite of management deficit at will. In freight transportation type, less-than-truckload(LTL) has more relation with above transportation feature than truckload(TL) does. Because freight transportation supply of TL is more flexible than that of LTL in correspondence of freight transportation demand. Relating to above mention, it appears that shortage of road and freight terminal of LTL is larger than that of TL. Especially in road and freight terminal comparison, shortage of freight terminal is larger than that of road. Shortage of road is the largest in 1990, and improved after-ward. But shortage of freight terminal is serious lately. So freight terminal needs more expansion than road, and shows better investment condition than road. Freight terminal expansion brings road expansion in LTL, on the contrary, freight terminal expansion substitutes freight terminal for road in TL. In transportation revenue, freight terminal's contribution to LTL is larger than that to TL. However, when we adjust quasi-fixed factor - road and freight terminal - to optimal level in the long run, in TL, diseconomies of scale becomes large, but in LTL, economies of scale becomes large. Consequently, it is necessary for TL to make counterplans to activate management of small size enterprises and owner drivers. And LTL should make use of economies of scale by solving the problem, such as nonprofit route, excess of rental freight handling of office, insufficiency of freight terminal, shortage of driver, and unpreparedness of freight insurance.

Considering the increasing trends of the consumption of livestock products in Korea, proper hygienic management and policies for ensuring their safety to protect public health and strengthen consumer confidence are demanded. It is particularly important to manage the livestock distribution processes to provide safe meat and meat products. This study was conducted to examine factors related to the hygiene management of livestock products and to check out the condition of hygienic management in meat markets. To accomplish this, 156 meat markets divided into HACCP-certified and non certified and evaluated for five factors, which received the following scores: facility and equipment management (1.00/2.0 points, 50.0%), storage and transport management (1.93/2.0 points, 96.5%), work place management (0.76/2.0 points, 38.0%), personal hygiene management (0.75/2.0 points, 37.5%), and inspection management (0.22/2.0 points, 11.0%). The results revealed that the scores of HACCP-certified meat markets were significantly higher than those of the non certified markets (p<0.05, p<0.01, p<0.001). These findings suggest that meat markets that are not HACCP-certified must improve hygienic management conditions and educate their employees to improve the safety of livestock products during distribution.

Mak-kimchi (shredded kimchi) which was prepared in a commercial factory was packed in bottle (200 g) under vacuum (560 mmHg) or atmosphere, and chemical characteristics and microbiological parameters were monitored during storage at 5, 15 and $25^{\circ}C$, respectively. Optimum ripening time of the kimchi at different temperature were 2 days at $25^{\circ}C$, 5 days at $15^{\circ}C$ and more than 60 days at $5^{\circ}C$. By vacuum treatment pH and acidity changes in kimchi were considerably retarded. The vacuum of each bottle released within 1 or 2 days at 25 or $15^{\circ}C$, respectively but the pack at $5^{\circ}C$ maintained more than 380 mmHg vacuum for 36 days and then the vacuum slowly released. The colour of kimchi (lightness, redness, yellowness) in bottle increased sharply at $25^{\circ}C$ and $15^{\circ}C$ but sustained a stable level with vacuum treatment at $5^{\circ}C$. The range of total viable count of kimchi in bottle was $10^7{\sim}10^{10}/ml$. The number decreased by storage temperature drop to $5^{\circ}C$ and even more vacuum treatment than atmosphere treatment at $5^{\circ}C$. Lactobacillus brevis, L. plantarum, L. acidophilus, Aerococcus viridans and Streptococcus faecium subsp. casseliflavus were identified in bottled kimchi and L. brevis and L. plantarum contributed to the main function during kimchi fermentation. Those main lactic acid bacteria decreased in numbers at $5^{\circ}C$ than 25 or $15^{\circ}C$ and even more declined in case of vacuum treatment.
