장기 수자원계획시 댐군의 연계운영을 위한 물수지분석 모형으로 HEC-5 모형과 K-ModSim 모형을 선정하고, 이에 대한 댐군의 연계운영 효과를 비교 평가를 수행하였다. K-ModSim 모형은 범용 우선순위 목적 선형최적화 모형으로, 조절점 및 저수지조작에 대한 우선순위를 지정할 수 있는 반면, HEC-5 모형은 목적별 저수지 조작의 우선순위가 지정되며, 등가저수지 개념을 사용하여 방류 우선순위를 결정하도록 되어있다. 이와 같은 연계운영 방식의 차이는 적정한 시기에 조절점에서의 물부족이 발생하는지 여부를 결정짓는 매우 중요한 요소이다. 따라서 본 연구에서는 가뭄발생 상황에 대한 각 모형의 연계운영효과를 비교 분석함으로써 급속히 변화하고 있는 수자원 이용환경에서 보다 합리적인 댐군의 연계운영 방안을 제시하고자 한다.

본 연구의 목적은 수문학적 분석과 다기준의사 결정을 사용한 계획 구성을 통한 하수처리수 재이용의 실현성을 보여주는데 있다. 안양천의 10개의 소유역을 대상으로 BOD와 유량에 대한 대안을 세워보았다. BOD는 각 유역에 3.0 mg/L 와 4.7 mg/L로 선정하였고 유량은 각 소유역에 따라 대안을 선정하였다. 대안에 따른 수문학적 분석은 Hydrological Simulation Program in Fortran (HSPF)을 사용하였다. 본 연구에서는 수질이 향상되고 요구되는 유량만킁의 증가가 있다면 하수처리수 재이용이 파괴된 물 순환의 회복에 얼마나 큰 영향을 미치는지에 대해 보여주었다. 추가적으로 대안의 우선순위를 선정하는데 있어서 다음의 세가지 경우을 비교하였다: 1) 물의 유량과 수질의 영향 그리고 2) 현재 나타나고 있는 유량과 수질의 수문학적 취약점에 대한 고려 마지막으로 3) 사회와 경제적인 측면에서 고려하였는지에 대해 비교하였다. 그 결과 세 가지 경우는 매우 다른 순위를 나타냈다. 그러므로 하수처리수 재이용에 대한 다양한 영향에 대한 고려사항은 유의 깊게 선택 되어야 하겠다.

This study aims to analyze the impacts of the QS Asia University Rankings (QSAUR) indicators and to compare the scores obtained by major countries. Hierarchical multiple regression was performed on the results of the QSAUR 2013-2015 and the average indicator and overall scores of each country were calculated. In the QSAUR, the most influential indicator was academic reputation. Each indicator's influence corresponded to its assigned weights and standard deviations. The results of the comparison revealed that Japan, South Korea, and China had the largest number of institutions among the top 150, while Singapore maintained the highest average scores on the indicators as well as the overall score. Each country had different areas that required improvement. South Korean colleges scored lower than some countries on academic reputation, papers per faculty, and international faculty. To attain higher ranks in the QSAUR, academic reputation, institutions' research capability improvement, and internationalization are needed. The implementation of these strategies is necessary to diminish the gap between South Korean institutions and other Asian institutions.

This study aimed to identify priorities in community pharmacist's roles in aged society using Analytic Hierarchy Process. We developed a survey questionnaire for AHP, which consisted of 19 pharmacist's roles selected from the FIP/WHO guidelines. The AHP survey questionnaire was self-administered by 127 pharmacists. The results showed that pharmacists put medication therapy management at the highest priority, preparation, dispense, distribution of medication at the second priority, and efficient healthcare system at the lowest priority. Among the 19 roles, new roles such as monitoring of medication therapy results, team-based health care, and transitions of care obtained relatively high priority.

The characteristics of the short document representatives and short queries of OPAC systems need the different ranking algorithms from IR systems. This study tested and analyzed the effectiveness of four sorting schemes and four ranking algorithms and the six effectiveness measurements for the ranked Boolean OPAC systems. The sorting by publication year was better but without significant difference. The cover density ranking was significantly better than the frequency-based ranking of the Fuzzy or DNF models. The simple effectiveness measurement based on the average rank of relevant documents retrieved was as good as the others and better than the precision P.

본 연구에서는 개선된 계층적 분석과정(AHP)을 사용하여 국산 신형 중형차의 우선 순위를 평가한다. AHP 모형은 외관, 성능, 안전성, 경제성, 영업사원, 사후정비의 주 기준과 39개 세부기준으로 구성된다. 구현의 특징을 (1) 샘플 크기가 작은 그룹의사결정 문제로 한정할 때, 한 의사결정자의 전체 쌍비교 행렬보다는 일관성비율이 한계치 이하의 행렬 만을 고려하였고, (2) 중요도 도출 과정에서 평가기준은 쌍비교 방식을, 대안은 레이팅 기법을 결합하였으며, (3) 그룹 중요도는 일관성 비율의 역수를 사용하였다. 사례 연구로 국내 자동차 판매 영업대표와 운전자를 대상으로 각각 평가기준에 대한 중요도와 레이팅 값을 도출, 3대 경쟁 차조의 우선순위를 비교 분석한다.

This paper is concerned about applying the AHP(Analytic Hierarchy Process) for a priority analysis of equipment operation plan to improve productivity of the container terminal in Gwangyang port. In this study, main elements of container terminal are assumed as into yard equipment area, transport equipment area, berth equipment area and C/Center area. A questionnaire is used to collect the opinions of equipment operating department and operational planning department. On the whole, the result of the analyses reveals that the most important area is yard equipment area. Examining each department is responses, equipment operating department preferred the C/Center area to other areas, on the other hand, operational planning department preferred yard equipment area. The result of this study suggests some guidelines for deciding priority of operation plan in the container terminal.

This study compared the characteristics of the optimization technique and the water supply and demand forecast using K-WEAP (Korea-Water Evaluation and Planning System) model and MODSIM (Modified SIMYLD) model considering wtaer supply priority. Currently, The national water resources plan applied same priority for municipal, industrial and agricultural demand. the K-WEAP model performs the ratio allocation to satisfy the maximum satisfaction rate, whereas the MODSIM model should be applied to the water supply priority of demands. As a result of applying the priority, water shortage decreased by an average of $1,035,000m^3$ than same prioritized results. It is due to the increase of the return flow rate as the distribution of Municipal and industrial water increases. Comparing the analysis results of K-WEAP and MODSIM applying the priorities, the relative error was within 5.3% and the coefficient of determination ($R^2$) was 0.9999. In addition, if both models provide reasonable water balance analysis results, K-WEAP is superior to GUI convenience for model construction and data processing. However, MODSIM is more effective in simulation time efficiency. It is expected that it will be able to carry out analysis according to various scenarios using the model.

This paper analyzes the priorities of introducing agricultural environmental conservation practices for the successful introduction of agricultural environmental conservation programs and promotes customized agricultural environment conservation practices packages suitable for the local environment. Agricultural environmental conservation practice consists of three fields: soil, water, and air, nine sub-fields, and 30 practice skills. Using the advantages of AHP and BWS appropriately for priority analysis, three areas and nine sub-fields are measured using AHP techniques, and the practical activities of each fields are measured by priorities using BWS techniques to enhance the differentiation and completeness of research. In addition, the criteria for evaluating priorities of practical activities used 'Environmental effectiveness' and 'Technical feasibility'. As a result of the priority evaluation, the 'Soil testing and reduction of fertilizer and livestock manure application' activities were evaluated as having the highest priority. Based on the results of the priorities for these practical activities, examples of customized practical activity packages by farming type and environmental conditions were presented.
