This study evaluated the accuracy of rainfall and flood forecasts in 8 sub-basins of Namgang Dam Basin by using numerical weather prediction of meso-scale model in the Japan Meteorological Agency. In the rainfall forecast result, we confirmed that the rainfall pattern was well predicted with the MSM updating, and corelation coefficient(CC) of Changchon, Sancheong, and Imcheon basin was close to 0.9, and MSM could catch the peak rainfall and time exactly. In the flood forecast result, CC was more than 0.7, showing the high correlation. As lead time increases, the forecast accuracy was gradually reduced, and the variability was steadily increased, but on the other hand, the forecasting accuracy became increased, and the variability also became reduced after 15 hours of the lead time. And it showed a tendency for the forecast uncertainty to be decreased as the basin area is increased. Through this study, it is considered that the MSM has a possibility to be applied to the domestic rainfall and flood forecasts, and it may be utilized as a primary data for the future basin management by providing it to the flood forecasting and warning. 본 연구에서는 일본 기상청의 메소스케일 모델(MSM)의 수치예보자료를 이용하여 남강댐 유역 내 8개 소유역에 대하여 강우 및 홍수 예측 정확도를 평가하였다. 그 결과, 강우예측의 경우 MSM이 업데이트됨에 따라 강우패턴을 잘 재현함을 알 수 있었으며, 창촌, 산청, 임천 유역의 경우 상관계수가 0.9에 가깝게 나타났고, 첨두 강우 및 시간을 정확히 재현하였다. 홍수예측의 경우 상관계수가 전체적으로 0.7이상으로 높은 상관성을 나타냈다. 선행시간이 증가함에 따라 예측 정확도가 감소하고 변동성이 증가하였으나, 선행시간이 15시간 이후에는 예측 정확도가 증가하고 변동성 역시 감소하였다. 유역 스케일에 따른 평가 결과 유역면적이 증가함에 따라 예측 불확실성이 감소하는 경향을 나타냈다. 연구를 통해 MSM은 국내의 강우 및 홍수예측에 적용가능성이 있다고 판단되며, 홍수 예·경보에 기초자료를 제공함으로서 향후 유역관리 등을 위한 기초자료로 활용 가능하다고 판단된다.

장애인고용시설설치비용융자사업 평가 및 개선방안

유완식,변민수 한국장애인고용공단 고용개발원 2011 수시과제보고서 Vol.2011 No.-

본 보고서는 한국장애인고용공단의 고용보험 위탁사업인 장애인고용시설설 치비용융자사업에 대한 효과 평가를 통해 융자제도 운영방식의 개선방안을 제시하기 위한 것이다. 공단의 융자지원DB(1993~2009)와 고용정보DB(2005~2009)를 시계열로 5개년 간 결합한 자료의 융자기업 623개와 비융자기업 13,751개를 분석한 결과 융자기업은 비융자기업보다 장애인 고용증가율이 0.95% 높은 것으로 나타났다. 그러나 융자기업의 장애인 고용증대효과는 중증장애인보다 경증장애인 고용증가에 기인하는 것으로 나타났다. 융자기간은 의무고용기간 10년 이후에도 고용효과가 커 융자사업이 장애인 고용유지에 기여하고 있고, 융자금액은 기업평균 3억원이상일 때 고용효과가 가장 높아 융자금액 지급단위 확대가 필요한 것으로 나타났다. 융자의 고용효과를 높이기 위해서는 대기업보다는 중소기업, 제조업이나 운수업보다는 이외의 업종, 장애인 고용률이 높은 기업보다는 낮은 기업에 융자하는 것이 보다 효과적인 것으로 나타났다. 이외 융자의 장애인 고용탄력성을 측정한 결과 0.29로 비탄력적인 것으로 나타났지만, 융자사업이 소기의 고용목표를 달성하고 있고, 2005년 0.23에서 2009년 0.30으로 효율성이 개선되고 있는 것으로 나타났다. 이러한 융자사업에 대한 실증분석 결과를 근거로 중증장애인 고용증가와 효과성 증대라는 두 가지 측면에서 제시한 융자제도 운영방식 개선방안은 다음과 같다. 첫째, 융자지급조건인 장애인 의무고용인원에 중증장애인 고용비중 부과, 둘째, 융자 의무고용기간 중 장애인 고용감소를 방지하기 위한 이자 납입기간 연장 또는 융자 원금상환기간 단축, 셋째, 융자지원 단위급액 확대, 넷째, 기업규모?업종?장애인 고용률에 따른 융자지원 대상기업의 다양화이다.

Purpose: There is no established treatment-related prognostic factor for gastric cancer except a curative tumor resection. This study was done to clarify the prognostic value of early postoperative intraperitoneal chemotherapy (EPIC) in patients with serosa-positive gastric cancer. Materials and Methods: We analyzed retrospectively the postoperative survival data of 209 patients with serosapositive gastric cancer treated by surgery and chemotherapy. The survival period for patients was calculated from the date of resection until cancer-related death or the last date of follow-up; Kaplan-Meier survival curves were plotted and compared by using the log-rank test. A multivariate analysis was done by using the Cox proportional hazards model. Results: Statistically significant differences in survival rates were noted based on gender, depth of invasion, lymph node metastasis, distant metastasis, stage, location of tumor, macroscopic type, extent of gastric resection, curability of surgery, and adjuvant chemotherapy. Five-year survival rates of patients who received EPIC and systemic chemotherapy were 49 per cent and 25 per cent, respectively (P=0.009). A multivariate analysis revealed that invasion of an adjacent organ, lymph node metastasis, total gastrectomy, and palliative surgery were poor independent prognostic factors. Also, EPIC had a marginal prognostic value (P=0.056). Conclusion: Perioperative intraperitoneal chemotherapy can possibly be one of the independent prognostic indicators in case of serosa-positive gastric cancer.

1. The traditional method of analyzing various problems involved in the foreign trade of a country and of determining factors of those problems is, in large part, not applicable to North Korea. The Soviet Union and East European Communist countries have, since the second half of the 1850's, shown a trend of adopting policies designed to rationalize their foreign trade: e.g.; decentralization, abolition of strict separation of trading business from industries, and extension of planning; thus relaxing the seriousness of the effects of those problems, North Korea, however, period still stands outside of this trend.<br/> 2. One of the most noteworthy factors which determines foreign trade policy of North Korea is the so-called "policy for self-supporting economy." This policy was first formulated as a result of the influence of the Stalinism which advocated that "all nations must have a certain consolidated industrial system for their own. "The emphasis on this policy has been further increased as North Korea's relations with the Soviet Union in the fields of politices, economics and military science became weak. Because of the over-exaggerated belief on autarky held by the leaders of North Korea, the profitablity in foreign trade has been disregarded, and at the same time the investment program of the country has been established without considering the profitability. The profitability in foreign trade is ignored in North Korea in proportion to the emphasis she gives to political consideration in establishing her foreign trade plans. In selecting foreign trade items and in establishing priority among them, the optimum structure for foreign trade is often desregarded because of the emphasis on the autarky policy. Throughout the period covering the Five Year Plan(1958~61) and the Seven Year Plan(1961~67) the top priority items for import have been machinery and plants. It is, however, notable that North Korea, in importing machineries and plants, is making positive efforts to approach West European countries and Japan in recent years.<br/> 3. In selecting counterpart countries for trade, North Korea considers political factors as economic factors. What is worthy of note in this respect is the fact the North Korea, which was generally contended with the bilateral trade relations with the Soviet Union in the 1950's began, from the early 1960's, openly to against the policy of depending on only one country, criticizing interference of domestic affairs by the Soviet Union, thus gradually, though there is still a limit, adopting a multi-lateral trading policy.<br/> 4. The foreign trade structure of North Korea has been modeled after that of the Soviet Union with Some modification. Therefore, the problems found in the Soviet style of trading structure are inevitably noticable in North Korea. For example, production and foreign trade are determined not by the maketing mechanism but by bureaucracies both in North Korea and the Soviet Union Various problems arise from this very fact. The most serious problems found in the foreign trade of north Korea are the facts that its program is based on unreal ground, the profitability is ignored, and there is no flexibility in implementing the program. These facts resulted from the extreme centraization in formulating trading program, separation of foreign trade from her industrial structure and from the practice of programming the plan on a short term basis. <br/> 5. The amount of foreign trade in North Korea has increased from $182,250,000(total amount of import and export) in 1949 to $ 415,680,000(estimate) in 1964. For several years following the end of the Korea War, North Korea depended entirely on the aid of the Soviet Union, Communist China and other Communist countries for her economic rehabilitation and development. Because of this the trading amount of North Kora reached pre-war level only in 1957. A relatively rapid increase in the amount of foreign trade from 1958 is attributable to
