대구 지역의 일개 종합병원에서 실시한 1992년 건강 검진 결과 중, 20세 이상인 성인들을 연구 대상자로 하여 근로자 검진과 공무원 검진 자료에서 당뇨병 집단검진 항목 중 요당, 공복혈당 그리고 식후혈당 검사 결과와 공무원 검진 자료에서 성, 연령, 신장, 그리고 체중에 관한 자료를 수집하여 분석하였다. 당뇨병 집단검진의 효율성을 비용효과분석 기법으로 비교하기 위하여 기존의 근로자 검진 방법과 공무원 검진 방법, 기존의 근로자 검진 방법에서 2차 검사 항목 중 요당 검사를 제외한 대안 (A), 공복혈당검사만 직장에서 실시하는 대한 (B), 식후혈당검사만 직장에서 실시하는 대안 (C), 공복혈당검사를 직장에서 실시하고 음성자에게 식후 혈당검사를 직장에서 실시하는 대안 (D), 식후혈당검사를 직장에서 실시하고 음성자에게 공복혈당검사를 직장에서 실시하는 대안 (E), 그리고 요당검사만 직장에서 실시하는 대안 (F)에 대해 당뇨병 유소견자당 투입 비용을 산출하였다. 각 대안별 유소견자당 투입 비용은 기존 근로자 검진 방법이 37,767원, 기존 공무원 검진 방법이 50,441원, 대안 (A)는 37,433원, 대안 (B)가 27,645원, 그리고 공복혈당 음성일 때 식후혈당 양성인 비율을 2%로 고정한 경우의 대안 (C)가 28,541원, 대안 (D)가 38,458원, 그리고 대안 (E)는 38,488원이었다. 그런데 대안 (F)의 경우 양성예측도가 93%인 경우 유소견당 투입 비용이 18,689원으로 가장 적었지만, 양성예측도가 20%일 때는 88,106원으로 가장 많았다. 양성예측도가 64% 이상일 때 대안 (F)가 가장 비용효과적이었다. 결국 대안 (B)와 대안(F) 둘 중 하나가 가장 효율적인 검진 프로그램으로 생각되며 이는 요당 검사의 양성예측도에 의해 달라질 것이다. To evaluate the efficiency of the diabetes mellitus screening program, the records of screening examinations for general workers and official workers at a general hospital in Taegu city were analysed. Six alternatives of the diabetes mellitus screening program were compared in terms of cost-effectiveness. The screening program I which was already used in the examination for general workers, screening program II for official workers, alternative program (A) which was the same method as screening program I without urine sugar test for the second examination in a hospital, alternative program(B) with the test for fasting blood sugar(FBS) in a worksite, alternative program (C) with the test for postprandial blood sugar(PPBS) in a worksite, alternative program (D) with the first test for FBS and the second test for PPBS of negatives for FBS test in a worksite, alternative program (E) with the first test for PPBS and the second test for FBS of negatives for PPBS test, and alternative program (F) with the test for urine sugar in a worksite. To compare the cost-effectiveness between alternatives, the cost (Won) per positive detected for diabetes mellitus (cost-effectiveness ratio) was calculated. The cost per positive detected was 37,767 Won for screening program I, 50,441 for screening program II, 37,433 for alternative program (A), 27,645 for alternative program (B), and if it was assumed that the positive rate for negatives of FBS would be 2.0%, 28,541 for alternative program (C), 38,458 for alternative program (D), 38,488 for alternative program (E). However, that for alternative program (F) was varied with the positive predictive value(PPV) of urine sugar test for diabetes. The cost per positive detected was lowest(18,689 Won) when PPV when PPV was 93%, whereas, highest (88,106) when PPV was 20%. The critical value of PPV was 64%. The alternative program (F) was most efficient when PPV was 64% or more. Considering the prevalence for diabetes mellitus, PPV for urine sugar test, and feasibility of screening examination, alternative program (B) will be proved as the most efficient screening program. In conclusion, either program(B) or program(F) will be the most efficient method for screening a large population depending on the positive predictive value of fasting urine sugar test.

感覺追求尺度(SenSation Seeking Scale)로 살펴본 體育系大學生과 非體育系大學生間의 特性比較硏究 : 體育系大學生은 球技選手와 格鬪技 選手로 區別함 Physical Educational Students: Classified by the part of ball game and grapple players

田炳冠 慶熙大學校 體育科學大學 1990 體育科學論叢 Vol.- No.3

This research has idea that can solve the problem already established, for it classified according to the social position, the educational career and the discrepancy of age among the individuals who became the object of study. On addition it examined clearly the distinctive quality of the scale of Sensation Seeking Scale(S.S.S). The research which already established(ex ; Humbaugh & Gumdershein, 1987) remains the problems which comes from the generalization of the results, are caused by no carrying out it mentioned above, also these laid merely 1 emphasis on the comparison of the total of S.S.S without cousidering how much affected by the four of the low scale. But as the result of this research, how-sports men gets lower arrangement than sports men in the total of Sensation Seeking Scale(S.S.S). There are mutnal actions on the line of a ball game and a grapple and low scale each others which affects to the characteristic of the sports games. This will contribute to the reconstruction of standard as one selects and teachs the player. The direction of research from this time on and the critical point of this paper ; Here is a discrepancy among the position of low scales with the line of ball games and grapples. But as divided on the distinction of sex, here exists a few problems, that is, in case of womenm, non sense statisticallg in spite of being different between the line of ball games(7.46) and grapples(7.36). This probably dues to the selection of the object. On the other hand, have the player who were selected in this research, the exact characteristic? But it is not so severe problem becames we can find that the grapple is superior to the ball game in the view of the distinction of sex, the discrepancy among the non-sports men and the DIS with men and women equally. I think that it such being below is avaible so that this research may help selecting and teaching the player. First, how will the expansion of exeriences of the line of game bring on a change of the characteristic? The longitudinal method is suitable for the solution of this problem. Second, we will have to study the quality of superior player(who have talent in his line of game)and inferior. This helps us discover the characteristic more exactly among the line of games.

최근 급격한 인터넷의 발전은 검색 서비스로 인해 주도되었다고 해도 과언이 아닐 것이다. 방대한 정보의 바다 인터넷을 통해 정보를 얻으려 해본 적이 있다면 어떤 검색엔진을 사용하여야 할지 어떤 검색어를 사용하여야 할지 한 번쯤은 고민 해 보았을 것이다. 이러한 이유로 많은 사람들이 메타 검색엔진이라는 것을 이용하게 된다. 그러나 이러한 메타 검색엔진도 자체내의 여러 가지 정보 처리로 인한 느린 결과 처리의 문제점이 있다. 본 논문에서는 인터넷의 정보검색을 하는 사용자의 특성을 고려한 정보 검색 서비스를 제공해 주는 시스템을 설계 구현하여 본다. It is needless to say that information search service leads explosive growth Internet. When you have a experience to get information what you search in Internet, puzzled about what kind of search engine and search keyword should select. Thus many people want to use Meta-search engine. But Meta-search engine has some problem. one of problem is that meta-search engine manages information which is obtained by several search engine. Thus meta-search engine has some severe performance degradation. In this paper we designed and implemented information search service system for the purpose of using internet to get information search result.

영양제로서 결정 NH₄H₂PO₄를 첨가한 피혁 공장 폐수의 생물학적 처리

전명순,임병란,최기덕,이수구 서울산업대학교 산업대학원 1993 大學院論文集 Vol.2 No.-

피혁 공장 폐수의 생물학적 처리에 있어서 유입 폐수의 급격한 부하변동, 독성물질의 유입 및 미생물의 성장에 필요한 각종 영양소의 불균형 등으로 인해 처리효율이 낮고 운전관리상 어려움이 많다. 따라서 본 연구에서는 피혁공장 폐수의 생물학적처리효율을 높이기 위하여 각종 영양제의 주입에 따른 처리효과에 관한 실험을 실시하여 적절한 영양제를 선정하고, 최적 주입량 등을 결정 하였다. 실험대상 폐수는 반월공단내의 피혁 공단 폐수로서 중화 및 응집참전 밥법으로 전처리 한 후 포기조에 유입되는 폐수를 대상으로 하였다. 영양제로는 회분식 실험에서 피혁폐수의 처리효율이 가장 우수한 것으로 나타난 결정 APM (ammonium phosphate monobasic, NH₄H₂PO₄)을 이용하였다. 연속식 활성 슬러지 공장에 있어서 폐수의 유량, 슬러지 반송율, 결정 APM 주입량 등을 변화시켜 그에 따른 처리효율에 미치는 영향을 실험 고찰하였으며, 생물 반응공학적인 반응해석을 통하여 설계에 필요한 반응상수 등을 구하였다. 연속식 활성슬러지법에서체류시간 12시간의 조건에서 영양제 미주입시 BOD 제거효율은 68%에 불과하였으나, 영양제로서 요소와 인산을 주입한 경우 73%로 증가하였으며 결정APM을 주입한 경우 90% 이상의 높은 처리율을 얻을 수 있었다. 결정 APM의 최적 주입량은 회분식 실험의 경우 300㎎/L이었으나, 연속식 실험의 경우 50㎎/L로 낮게 나타났는데, 이는 반송되는 슬러지내의 높은 인농도와 미량원소에 기인한다. 결정 APM을 50㎎/L 주입한 후 수리학적 체류시간을 6∼30 시간의 범위로 변화시켜 실험한 결과, BOD 제거효율은 체류시간 6시간에서는 67%에 불과하였으나, 12시간의 경우 93%, 30시간의 경우 98%이었다. 따라서 BOD제거효율 90%이상을 얻기 위해서는 수리학적 체류시간은 11시간 이상, F/M비는 0,65 ㎏ BOD/㎏ MLVSS·d 이하로 운전하여야 하는 것으로 나타났다. This study was performed to enhance the treatment efficiency of leather wastewater adding APM(ammonium phosphate monobasic, NH₄H₂PO₄) crystal as nutrient which contained the sufficient mineral components. The effect of APM crystal on biological treatment were studied and its optimum dosage and kinetic coefficients were determined. In the continuous activated sludge system for field wastewater of Banwol leather complex, BOD removal efficiency could be obtained over 90% with adding APM crystal, while it was 68% without nutrients and 73% with urea and phosphoric acid in the condition of HRT 12hr and SRT 3 days. The optimum dosage of APM crystal was 50㎎/L which was low compared with 300㎎/L in batch test due to recycling sludge contained high content of phosphate and mineral nutrients. In the condition of adding APM crystal 50㎎/L and hydraulic retention time in the range 6∼30hr, BOD removal efficiencies were 67% for HRT 6hr, 93% for 12hr and 98% for 30hr. In order to obtain over 90% of BOD removal efficiency, HRT should be maintained over 11 hr and F/M ratio within 0.65 ㎏ BOD/㎏ MLVSS·d.

Reviewing the literature of human resources management, we found researchers have explored different impact factors of organizational characteristics, interpersonal characteristics, levels of perceived activities on job satisfaction. In this paper, we add a new factor that includes interactive effects of organizational characteristics and interpersonal characteristics on job satisfaction. Utilizing structural equation modeling, we test our proposed model among female employees in the financial institution. The Structural Equation Modeling approach has been employed to investigate the cross influences among the four categories. The proposed model produces the best fit. The organizational characteristics category is the most important effect among categories of the proposed model of job satisfaction. Additionally, the theoretical and managerial implications are discussed.

A demand forecast for a Kwangju City Logistics Complex has been made in this paper. A forecasted shipments quantity is utilized to forecast industrial demands of the complex for the years 1999 and 2003, respectively. The forecasted size of the logistics complex is 317,000 pyung in 1999 and 613,000 pyung in 2003. We also analyze anticipated a cargo volume demand to determine how large the complex should be in order to satisfy such a demand. The size of the complex varies according to the utilization rate of the complex. For instance, a utilization rate of 25% will mandate a logistics complex of 362,000 pyung in 1999 and 540,000 pyung 2003. Forecasting future demand of the complex using either the shipments model or the cargo volume analysis model is not error-free. Demand forecasting is not a totally precise science. In an effort to make our predictions more reliable we must average the results of the two methods. Such calcuations require that 340,000 pyung in 1999 and 540,000 pyung in 2003 be allocated for the project, with a percentile distribution of 30% for facilities, 31% for the building lot area and 39% for supplementary facilities. In addition to forecasting the size of a logistics complex we also forecast the size of a depot: that is, 120,000 pyung in 1999, 160,000 pyung in 2003 for total area and 25,000 pyung in 1999, 30,000 pyung in 2003 for freight terminal and 70,000 pyung in the period for the wholesale center.
