  • In carrying out the prior review on environmental conditions for basic plan of public waters reclamation, the important item is review on conditions of location on prearranged reclaimed land. In this study, environmental assessment which needs careful consideration in the first stage of selecting location is presented by analyzing environmental impact assessment on public waters reclamation projects for about 10 years. The assessment index for alternative comparison is divided into two parts according to importance level. What is most important in alternative comparison is the comparison on direct influence due to reclamation. In other words, it figures out damaged extent of natural shoreline as well as intertidal and infralittoral zones. Comparing influence extent due to reclamation through the 1st comparison on this is regarded as to be important. In case there is no significant difference by alternatives through the 1st assessment, the 2nd assessment should be carried out. In the 2nd assessment indexes are damaged quantity of benthic organism, change in seawater current, erosion, accumulation and exchangeable rate of seawater. The plan for selecting optimal location which minimizes environmental influence in establishing public waters reclamation plan is demonstrated through model cases. For this, 3 districts which have similar environment and scale are selected, and then comparison on location alternative is made through environmental assessment index. In addition, the comparison on 3 arrangement alternatives are conducted, targeting certain areas. It is thought that carrying out comparison review on respective areas in the same cities and counties, not merely comparing arrangement plan by selecting 1 targeting area in advance, is the most appropriate. Besides, selection of arrangement plan considering environment, which minimizes damage of natural shoreline and influence due to change of seawater current is required in alternative comparison on arrangement plan as well. In case of the prior review on environmental conditions though alternative comparison method presented in this study is carried out, it is safely said that the influence on ocean environment due to public waters reclamation can be minimized.

  • This study used the nearest feature model to connect forest patches within the western Geum River Basin. Due to many different forest patch sizes, 3 alternative methods were tested to determine the best way to establish an ecological network with forest patches. Alternative 1 used all forest patches to determine whether patches were large enough. Alternative 2 used forest patches over 10 ha in size. Alternative 3 used natural conservation indices to select forest patches containing better qualities in the natural conservation level. As a result 635 out of 724 patches of over 10 ha were selected for comparison. Alternative 1 showed that forest patches of less than 10 ha were outliers interrupting the establishment of the ecological network. They generated an unnecessary ecological network to link core areas to comparison features. The ecological network was improved by using forest patches greater than 10 ha in size(Alternative 2). Each comparison feature was much more hierarchically connected to core areas in Alternative 2 than in Alternative 1. Forest patches filtered by natural conservation indices were useful for obtaining the best ecological network. Alternative 3 clearly showed the connections in the ecological network between core areas and forest.

  • 주관적 행복이 각광 받고 있다. 주관적 행복에 따라 사회비교 및 인지부조화 해소가 달라지는 것처럼, 주관적 행복이 소비자의 대안 비교와 평가에 영향을 미칠 것이다. 본 연구는 소비자가 선택한 혹은 선택하지 않은 대안에 대한 추가 정보로 인해 대안의 절대적 가치 및 상대적 가치가 변동할 때, 대안에 대한 평가가 소비자의 주관적 행복에 따라 어떻게 달라지는지 연구하는 것을 목적으로 하였다. 특히, 소비자가 제품에 대해 지각하는 가치를 반영하는 소비자가 생각하는 대안의 적정가격을 사용하여 대안에 대한 평가를 측정하였다. 즉, 선택 혹은 비선택 대안의 상대적 가치 및 절대적 가치의 변화가 대안의 적정가격에 미치는 영향이 주관적 행복에 따라 달라지는지 살펴보고자 하였다. 연구를 위하여 98명의 대학생을 대상으로 실험을 실시하였다. 먼저, 학생들을 두 집단(비선택 대안 악화, 선택 대안 개선)에 무작위 할당한 후, 실험실 모니터에 2개의 대안에 대한 소비자 리포트를 제시하였다. 학생들이 하나의 대안을 선택하면, 대안에 대한 소비자 리포트의 평가가 변동(비선택 대안 악화, 선택 대안 개선)하면서 비선택 대안의 가격이 주어지고, 학생들은 선택 대안의 적정가격을 답하였다. 2주 후 학생들의 주관적 행복을 설문지로 측정하였다. 연구 결과, 집단, 주관적 행복의 단순효과 및 이 둘의 상호작용효과가 유의하였다. 또한, 행복한 사람은 비선택 대안이 악화될 때 보다 선택 대안이 좋아질 때 선택 대안의 적정가격을 높게 평가한 반면, 불행한 사람은 이러한 차이가 없었다. 이는 행복한 사람은 선택 대안의 절대적 가치 상승에 민감한 반면, 불행한 사람은 선택 대안의 절대적, 상대적 가치 상승 모두에 민감하며, 불행한 사람은 행복한 사람보다 비선택 대안의 악화 정보에 집중함을 의미한다. 본 연구는 소비자의 주관적 행복이 대안 평가에 미치는 영향을 제시함으로써 기존 연구를 확장하였다. 특히, 타인의 존재가 명시되지 않은 상황에서도 행복한 사람보다 불행한 사람이 부정적인 사회비교 정보에 민감함을 보였다는 점에서 이론적 의의가 있다. 아울러, 이러한 결과는 소비자의 주관적 행복 수준에 따라 대안을 어떻게 제시해야 하는지에 대한 시사점을 유통업체들에 제공한다. 본 연구는 한국의 소비자를 대상으로 진행하였으나, 향후 연구에서 국가간 차이를 비교하는 것도 의미 있을 것이다. 또한, 주관적 행복이 대안 평가에 미치는 영향의 메커니즘을 밝히기 위하여 예상되는 후회감, 고통, 기쁨 등을 매개변수로 놓고 추가 연구를 진행할 필요가 있다.

  • Students often have tenacious physics misconceptions and many studies were conducted on engendering conceptual change. Correspondingly, there is much literature on alternative assessment and its role in student learning. This is a comparison study on using alternative assessments to improve common students' misconceptions in GCE Advanced Level Physics. This research also aims to affirm alternative assessment as a valid tool for learning and promote its use. This study involved two classes with 24 students each. For four weeks, electromagnetism was taught to students using the same classroom pedagogies but with different assignments. The control group completeda standard drill-and-practice assignment while the experimental group finished an alternative assessment. From the preliminary results, students who undertook the alternative assessment and the traditional assessment both improved, however, the treatment group did not perform statistically significantly better than the control group. The reasons will be discussed and commented and it is expected to have significant improvement on rectifying misconceptionsupon next batch of experimentation groups.

  • For the productivity improvement, it is necessary to analyze problem of the system and evaluate alternative plans. But, it if hard to experiment and evaluate alternative plans in real existing system. Therefore, it is necessary to synthetically analyze and evaluate alternative plans using simulation and statistical analysis method. In this case study, as a simulation language, Promodel is used to compare and evaluate four alternatives which are considered to improve the productivity of an object system. The object system is constituted of a pretreatment line and a painting line. The purpose of this study is to analyze whether the decrease of the down time in pretreatment line can be effective to the productivity improve comparing with exiting system and other alternatives. The other purpose is to choose an alternative that has the best productivity improvement. The results of the simulation show that the possibility of improvement in productivity by decreasing the down time of pretreatment line. Two-Stage Bonferroni Procedure is used to choose the best alternative.

  • The procedure of predicting the construction cost and selecting the best alternative is performed based on comparative review of each building case. In the case of office building, it is required continuously until design is complete, since the owner requirements are various and likely to change during the design process compared to a standardized apartment. However, since the comparison work for each alternative in practice uses only the unit construction cost, there is no correlation between the alternative and the final result, and it is difficult to quantitatively determine the effect of the determined design factor on the total construction cost. It is needed that a means to support the generation of design alternatives using similar building cases during the design phase. This paper proposes a BIM-based data replacing process to support creating and comparison of design alternatives of internal finishing for office building. When design alternatives are created through the proposed process, it is possible to compare several similar cases with current project under equivalent design circumstance. Because only some finishing properties are replaced while maintaining the shape information such as the length, height, and base constraint of the object to be replaced.

  • The gap-based SERVQUAL model is a popular service quality determinant due to its superior diagnostic capacity over alternative explanatory frameworks. However, some researchers criticize the performance of the SERVQUAL model and propose alternative service Quality measurement constructs. Nevertheless, it is argued that the superior diagnostic capacity of SERVQUAL is its key strength; and that any criticism made of it when making comparison with alternative models does not reflect the differing nature of scales of statistical analysis. Arguably, the only limitation of a gap-based model is misinterpretation of customers' evaluation and perception of a service. In this research, the gap score is transformed into a ratio score. Also, empirical tests and implications are presented to support this alternative contribution to the body of knowledge.

  • Lately, our world is faced with very serious problems related to the increased air pollution of the exhaust emissions from automobiles. In particular, the exhaust emissions of diesel engines are recognized as a main cause which strongly influence environment. Lots of researchers have attempted to develop various alternative fuels to reduce these harmful emissions in diesel engine. The purpose of this investigation is to evaluate the possibility of esterfied rice bran oil for diesel fuel substitution in a naturally aspirated D. 1. diesel engine, and also find means to reduce smoke emissions in esterfied rice bran oil combustion. The smoke emission of esterfied rice bran oil is reduced remarkably in comparison with commercial gas oil, that is, it was reduced approximately 58.2% at 2500rpm. But, power, torque and brake specific energy consumption didn't have no large differences. It was concluded that esterfied rice bran oil can utilize effectively as an alternative and renew- able fuel fur diesel engine.
