In the process of devising an efficient meal service system for the elderly, 478 elderly were interviewed at 6 different social centers with the elderly meal service program in Seoul area to monitor degree of satisfaction and/or needs of the beneficiaries regarding the program. The survey was conducted during the month of December 2002 by well-trained interviewers using self-developed questionnaire. Results were analyzed statistically using SAS package program. Most of the beneficiaries were low economic class and 76% of them had doctor diagnosed disease(s). Mean satisfaction score of the beneficiaries of congregate meal service was 3.72 out of 5. For most of the questions, female elderly and healthy elderly responded with higher score than male elderly and unhealthy elderly, respectively(p<0.05, p<0.01). On the other hand, beneficiaries of the home-delivered meal service were little bit less satisfied with the service(3.54 out of 5). Compared to the beneficiaries of congregate meal service, larger portion of beneficiaries of home-delivered meal service wanted more meats(28.5% vs. 17.1%) and vegetables(23.2% vs. 12.3%) as side dishes. On the other hand, the most preferred type of cooking and/or seasoning was stewing for both cases. Based on these findings, it is suggested that more fresh foods should be used than processed foods in the preparation of meals for the elderly and, more fish-, meat- and vegetable- dishes should be served to come up to the needs of the elderly. Onto this, mainly Korean style meals with some intermittent Western, Japanese or Chinese style meals served at the right temperature would suffice most of the elderly needs.

Land use and social, cultural and environmental safety, which are adapted to natural environment, based on the traditional agricultural society, are on the verge of collapse because our rural community was developing around economy value. Rural landscape has not been certified compared with urban and natural landscape in importance by the standard of functional aspect, economic value and use demand, so cultural, historical, traditional and agricultural landscape native to rural community are not evaluated exactly. The Purpose of the study is a efficient plan and management for a essential rural landscape. Therefore We Make out a landscape diagram for efficient landscape plan and management and Selection of the Rural Landscape Management Area.

Outsourcing is the most recent management tool to emerge in response to demands for more efficient ways to address organizational competitiveness. Organizations, recognizing that they cannot be world class in every activity and function involved in producing their products and services, are moving toward business strategies based on "core competencies". Researchers in information systems propose several reasons why firms outsource their IS, including reducing costs, generating cash, focusing on core competencies, and gaining access to technical expense. But many studies were examined into environmental factors of outsourcing success - market circumstance, uncertainty, relationship of outside vendors. This study focused on internal factors of outsourcing success - relationship between activities or functions of outsourcing and motivation, job involvement, job satisfaction of employees. I examine the relationship between outsourced job activities and job involvement of employees in information system department, based on survey from 25 firms.

강원도는 오랫동안 금속, 비금속, 석재 및 석탄과 같은 지하자원들을 공급하는 국내 주요생산지로 알려져 왔으나, 장기적인 채광과 비 계획적인 생산으로 인하여 매장량이 고갈되고 있으며, 대외적으로 생산 경쟁력 마저 잃어가고 있다. 이러한 문제점에 대한 해결방안의 일환으로 본 연구에서는 강원도내에 산재되어 있는 지하자원의 분포, 자원 생산시설 및 생산량, 경제성, 자원개발, 환경문제 등 자원관리에 필요한 제반사항을 수행할 수 있는 강원지역 자원 종합관리 GIS 시스템을 개발하였다. 이 시스템의 개발은 방대한 양의 정보 조사 및 저장, 오랜 개발기간, 많은 소요인력 및 개발 비용이 요구되기 때문에 본 연구에서는 조기에 자원관리 GIS 시스템을 개발하여 이와 관련된 생산 및 연구 분야에 조기에 적용할 수 있도록, 일차년도에는 현재 석재복합 신소재제품 연구센터의 집중적 연구대상 지역인 태백지역에 대한 탄광지역을 중심으로 자원 종합관리 GIS 시스템을 개발하였다. The Kangwon province has been well-known to be one of major underground resource producing districts which are mainly supplying metals, non-metals, stones, and coals. However, due to the long-term mining and unplanned production, the natural resource reserves have been rapidly drained and oversea production competition has been losing. In this study, we has developed a GIS system for regional resource management in the Kangwon province, which can operate, maintain, and manage the distribution of underground resources, resource production facilities, production and economic development, and environmental issues. The development of this system requires the collection, analysis, evaluation, and storage for a huge amount of research data, and in addition, the long period of time, the big research man power, and big development cost. Accordingly, to shorten the development period of time and to early apply itself to production, this stage of study has been intensively developed a regional resource GIS system for managing the mines scattered in the Tabak province, which is one of hottest RRC's research areas.

A novel Camera Calibration Method is proposed by employing the perspective transformation matrix with scale factors for the accurate Robot Vision System, where the calibrated scale factors are horizontal scale factor, computer image center coordinate, and camera lens distortion coefficient. By using those factors, the image coordinate with distortion in computer frame grabber is transformed to the undistorted coordinate, in which calibration is performed. To show the validities of the proposed method, several experimental results are illustrated with comparison of the other calibration methods.

레이저 클래딩 중첩도가 표면특성에 미치는 영향

A 4kW RS840 CO2 laser with a powder auto-feeding apparatus has been used to deposit multiple overlapping tracks of Ni-base superalloy on to low carbon steel. It was found that the surface roughness(turbulence) of an overlapped cladding layer decreased with the increase of the overlapping ratio in an oscillating manner. When the overlapping ratio had values of 0.62, the surface turbulence was lowest. Overlapping ratio offer significant potential for improvement of materials surface properties such as corrosion performance and wear resistance. This paper reports that the overlapping ratio shows best corrosion resistance. The tensile residual stresses generated at the higher overlapping ratio(>0.45) and the element concentration of Fe increased in the surface layer at the lower overlapping ratio(<0.45) may lead to worse corrosion resistance.

菜蔬栽培土壤과 菜蔬類의 有機鹽素系 殺蟲劑의 殘留量을 評價하기 爲하여 GLS로 分析하여 얻은 結果는 다음과 같다. 土壤總平均殘留量은 상치土壤(0.166ppm), 시금치土壤(0.158ppm), 마늘土壤(0.105ppm), 쑥갓土壤(0.095ppm), 고구마土壤(0.080ppm), 배추土壤(0.063ppm), 아욱土壤(0.046ppm), 토마토土壤(0.027ppm) 順으로 높았다. 菜蔬의 總平均殘留量은 상치(0.038ppm), 시금치(0.022ppm), 마늘(0.015ppm), 아욱(0.013ppm), 고구마葉(0.012ppm), 당근(0.009ppm), 오이(0.008ppm), 배추(10.007ppm), 쑥갓(0.002ppm), 토마도(0.002ppm)順으로 높았으며, 土壤中의 總平均殘留量이 菜蔬中의 總平均殘留量보다 5~10倍 높았다. 菜蔬中의 總平均殘留量은 土壤中의 總平均殘留量에 比例하였다. α-BHC, γ-BHC는 土壤試料 및 菜蔬試料 全體에서 檢出되었다. 한편 PCNB, heptachlor, p, p'-DDE, dieldrin은 土壤試料에서는 平均殘留量 範圍가 栽培作物에 따라 各各 ND~0.004ppm, 0.001~0.017ppm, T~0.031ppm, T~0.032ppm이었으나 菜蔬試料에서는 거의 檢出되지 않았다. 供試菜蔬의 BHC, DDT汚染이 廣範圍하였지만 全體的인 殘留分의 水準은 FAO/WHO가 奬勵한 食品中 BHC, DDT 殘留許容限度인 0.5ppm, 1.0~7.0ppm에는 훨씬 未達하였다. Evaluation of levels of organochlorine pesticide in vegetables and agricultural soil samples were analysed by GLC equipped with electron capture detector. The result obtained were summarized as follows; Total mean residues of organochlorine pesticide in soil increased in the order of tomato soil(0.27ppm), cucumber soil(0.042ppm), marsh mallow soil(0.046ppm), cabbage soil(0.03ppm), sweet potato soil(0.080ppm% carrot soil(0.090ppm), crown daisy soil(0.095ppm), garlic soil(0.105ppm), spinach soil(0.158ppm), and lettuce soil(0.166ppm). Total mean resideues of organochlorine pesticide in vegetables increased in the order of crown daisy(0.002ppm), tomato(0.002ppm), cabbage(0.007ppm), cucumber(0.008ppm), carrot(0;009ppm), sweet potato leaf (0.012ppm.) marsh mallow(0.013ppm) garlic(0.015 ppm) and lettuce(0.038ppm). Levels of residue in soil was 5~10 times higher than those of vegetables. The similar trend appeared between levels of residue in soil and those of vegetables. α-BHC and γ-BHC were detected in all soil and vegetable samples. The mean residue levels of PCNB, heptachlor, p, p'-DDE and dieldrin in all soil samples were ND~0.004ppm, 0.001~0.017ppm. T~0.031ppm and T~0.032ppm, respectively, but those of in vegetable samples were hardly detected. In spite of high detection frequencies of BHC and DDT in vegetables, the levels of BHC and DDT pesticide residue in vegetables were found fairly low and were far lower than the tolerences for respective vegetables recommended(0.50ppm, 1.0~7.0ppm) jointly by FAO and WHO of United States.

To evaluate the efficacy of the single agent therapy for the initial management of fever in neutropenic patients, we conducted a prospective randomized trial comparing imipenem/cilastatin alone with a combination of piperacillin and amikacin. Among 40 evauable episodes of fever, stratum A(hematologic malignancy, n=30) consisted of 15 imipenem group and 15 piperacillin plus amikacin group and stratum B consisted of 10 cases with solid tumor. There was no difference in age, sex, duration of neutropenia, initial granulocyte count and number of cases with severe neutropenia(<100/㎣) between two groups. Overall response rate to imipenem was higher(86.6%) than combination therapy group(53.5%) in stratum A, but statistical difference was not found. Overall response rate to imipenem in solid tumor was 100% whereas to combination therapy group was 40%. There was no serious toxicity on imipenem use. We conclude that imipenem monotherapy could be an effective & safe empirical therapy in the treatment of febrile neutropenic patients.
