The rapid progress of the intermodal freight transportation in recent years has induced fierce competition among the adjacent hub ports for container transport. This brings increased attention to the evaluation of the port competitive ability. But it is not easy to evaluate the port competitive ability because this belongs to ill-defined system which is composed of ambiguous interacting attributes. Paying attention to this point, this paper deals the competitive ability of container port in Far-East Asia by fuzzy integral evaluation which is adequate to interacting ambiguous attribute problem. For this, the proposed fuzzy evaluation algorithm is applied to the real problem, based on the factors such as cargo volumes, costs, services, infrastructure and geographical sites These are extracted from the precedent study of port competitive ability, etc. The results show that the port evaluation factors come in following order ; services, costs, infrastructure, geographical sites and cargo volumes. There are some interactions(interaction coefficient, ${\lambda}=-0.664$ between evaluation attributes. The port competitive ability comes in following order : Singapore, Hongkong, Kobe, Kaoshiung and Busan. According to the sensitivity analysis, the rank between Busan and Kaoshiung changes when ${\lambda}=0.7$. From the analysis of the results, we confirmed that the proposed fuzzy evaluation algorithm is very effective in the complex-fuzzy problem which is composed of hierarchical structure with interacting attributes.

Purpose: The purpose of this study was to develop a module for infants in pediatric nursing based on problem-based learning (PBL) and to analyze its effect. Methods: The data used in the study was collected from 79 junior nursing students. For the analysis of the module effect, one group post-test design was applied for measurement of academic achievement. Results: The module for infants is comprised of a 4-hour PBL module. The academic achievement tests are composed of formative (tutor evaluation, self-evaluation) and summative evaluations. The self-evaluation revealed the strong need for PBL and the importance of PBL in the problem solving process and integrative thinking. The mean score of the subjects' learning satisfaction, problem solving process and concept map assessments were all above 50 percent. There was no significant difference in the mean score between the infant PBL and other teaching methods. Conclusion: The PBL proved to be a useful learning method to promote the critical and integrative thinking process.

This study conducted a case study on the process-centered evaluation competency of a middle-school/high-school science teacher using Teacher's Process-centered Evaluation Competency (T-PEC) measurement tool. The case analysis shows that teacher A in a middle school represents high competency of process-centered evaluation planning and cooperative communication while the competency of utilizing process-centered evaluation results is low owing to the characteristics of non-standardized areas. Teacher B in a high school shows high level of cooperative communication competency whereas low level of process-centered evaluation execution competency because the freedom given to students is not enough during the process of evaluation. The teacher also shows very low level of utilizing process-centered evaluation results due to the lack of time and the school culture not giving feedback to the students. According to cross-case analysis, teacher A and B both represent the highest level of collaborative communication competency and the lowest level of utilization process-centered evaluation results competency. And the lack of clear criteria for process-centered evaluation leads to different understanding of process-centered evaluation between the two teachers, and teacher B shows low the level of utilizing process-centered evaluation affects results due to the students not being concerned on feedback, security problem, and the reality focusing on the university entrance examination in high schools. Based on the results, this study suggests providing clear guidelines of process-centered evaluation to teachers, introducing an application in order to solve the time-lack problem pointed out as the biggest problem of process-centered evaluation, ensuring objectivity and security about process-centered evaluation results, and building the school culture such as the expanded application of standardized areas in order to implementing process-centered evaluation.

본 논문의 목적은 효율적인 문제중심학습을 적용하기 위한 평가방법을 개발한다. 연구 대상은 창의공학설계 교과목을 수강한 H대학 1학년 학생 68명 이었으며, PBL수업은 12주에 4개의 PBL문제를 적용하였다. PBL의 효율성을 관찰하기 위하여 학생들은 주어진 문제의 PBL 활동 과정에서 평가지를 작성하여 제출하였다. 또한 PBL 활동이 끝날 때 마다 평가지와 성찰일지를 작성하여 제출하였다. 연구 결과는 PBL에 대한 이해, 학습 내용에 대한 이해, 협동학습에 대한 이해, 자아성찰, 실제적 경험, 창의문제 해결력, 자기주도적 학습 능력, 의사소통 능력, 문서작성 능력, 프리젠테이션 능력, 관찰 능력, 평가 능력과 같은 다양한 PBL의 효과를 경험한 것으로 나타났다. PBL 활동에 대해서는 지난 학기에 비하여 자신감, 만족감, 성취감도 높았으며, PBL 수업이 매우 유용했다고 응답했으며, 수업에 대한 만족도도 높았다. 그러나 PBL 활동 과정에서 팀원들 간의 의사소통문제, 함께 모이는 문제, 적극적으로 참여하지 않는 팀원 문제, 시간이 소용되는 문제가 나타났다.

Recently, Fuzzy theory has been applied in evaluation problem. Fuzzy evaluation based on Fuzzy theory can accommodate fuzziness of judgement with people through introducing Fuzzy measure. Representative Fuzzy evaluation is Fuzzy Integral using Fuzzy measure. Definite methodology using Fuzzy Integral HFI(Hierarchical Fuzzy Integrals), HFEA(Hierarchical Fuzzy Evaluation Algorithm), HFP(Hierarchical Fuzzy Process), etc. In this paper, we deal with problem identifying evaluation value using Fuzzy Relation Equation at these Fuzzy evaluation. We verify relation between Input data and Output data through @-operation and apply this to HFP. And that we verify evaluation value which objects of evaluation are able to possess.

This paper analyzed md developed flow - shop sequencing heuristic method. The essence of the heuristic approach is in the application of selective routine that reduce the size of a problem. The advantages of this approach are consistency. Speed, endurance and the ability to cope with more data and larger systems than is humanly possible, In recent years many heuristic procedures have been suggested for the flow - shop sequencing problem. Although limited comparisons of these procedures have been made, a full scale test and evaluation have not been reported previously. The maximum flow - time criterion is selected as the evaluation criterion is selected as the evaluation criterion of flow - shop's efficiency. The author evaluated these 3 heuristic method's performance. By the evaluation of the result, we can see that the modified methods produce a shorter maximum flow - time than the original methods.

In this paper, we consider a problem of partitioning a search area into smaller rectangular regions, so that multiple platforms can conduct search operations independently without requiring unnecessary coordination among themselves. The search area consists of cells where each cell has some prior information regarding the probability of target existence. The detection probability in particular cell is evaluated by multiplying the observation probability of the platform and the target existence probability in that cell. The total detection probability within the search area is defined as the cumulative detection probability for each cell. However, since this search area partitioning problem is NP-Hard, we decompose the problem into three sequential phases to solve this computationally intractable problem. Additionally, we discuss a special case of this problem, which can provide an optimal analytic solution. We also examine the performance of the proposed approach by comparing our results with the optimal analytic solution.
