The purpose of this study is to analyze the patterns of commercial Cheollik dresses by size analysis and wearing evaluation. Six kinds of commercial Cheollik dress patterns distributed on the market were selected and classified into two types group, A type group(A-1, A-2, A-3) consisting of flat type sleeve pattern and B type group(B-1, B-2, B-3) consisting of three-dimensional type sleeve pattern depending on the sleeve type. The size of the Cheollik dress pattern was analyzed, and wearing evaluations of the appearance, movability were carried out. Cheollik dress pattern was made in various size and many patterns were produced in the form of omission of components such as seop. It should be based on the understanding of the form and composition of the traditional Cheollik for pattern development. As a result of the wearing evaluation, A-2 showed the highest evaluation in the appearance and movability evaluations in type A. B-2 was the highest evaluation in appearance evaluation in type B. But in the evaluation of the movability, B-2 received the lowest evaluation because of little allowance. Therefore, the allowance in clothes should be considered enough for the movability. The result of this study can be provided as a basic data for the development of Cheollik dress pattern reflecting modern trend and the traditional beauty.

A systematic and multi-dimensional analysis in evaluation results may play a role of providing both learners and instructors with essential information. Conventional types of evaluation research have a tendency of partiality for developing evaluation tools, and analyzing the evaluation results has mostly been fragmentary and a one-dimensional analysis. In this study, through analyzing evaluation results in a multi-dimensional way, a multi-dimensional evaluation result analyzing system was developed for the purpose of providing various information for both learners and instructors to accomplish quality learning teaching. Dimensions are classified into four dimensions including period, student, difficulty degree, and evaluation domain. Analysis results are presented in various types of Dcube, graphs, and spreadsheets.

This study suggests 5 evaluation criteria (safety and technology, environmental impact, economic feasibility, social factors, and institutional factors) and 24 evaluation indicators for a NFC (nuclear fuel cycle) derived using factor analysis. To do so, a survey using 1 on 1 interview was given to nuclear energy experts and local residents who live near nuclear power plants. In addition, by conducting a factor analysis, homogeneous evaluation indicators were grouped with the same evaluation criteria, and unnecessary evaluation criteria and evaluation indicators were dropped out. As a result of analyzing the weight of evaluation criteria with the sample of nuclear power experts and the general public, both sides recognized safety as the most important evaluation criterion, and the social factors such as public acceptance appeared to be ranked as more important evaluation criteria by the nuclear energy experts than the general public.

Nonlinear analysis for seismic performance evaluation of existing building usually takes 4~5 times more than linear analysis based on KBC code. To obtain accurate results from the nonlinear analysis, there are a lot of things to be considered for nonlinear analysis modeling. For example, reinforcing layout, applied load and seismic details affect behavior of structural members for the existing building. Engineer-oriented computerized system was developed for engineers to evaluate effective seismic performance of existing buildings with abiding by seismic design principles. Using the engineer-oriented program, seismic performance evaluation of reinforced concrete building was performed. Nonlinear hinge properties were applied with real time multiple consideration such as section layout, section analysis result, applied load and performance levels. As a result, the building was evaluated to satisfy LS(Life Safety) performance level. A comparison between engineer-oriented and program-oriented results is presented to show how important the role of structural engineer is for seismic performance evaluation of existing buildings.

The analysis of characteristics of water use evaluation and nighttime domestic flow evaluation was performed by using result from flow monitoring and surveying water supply records and nighttime domestic flow for a year. The analysis of correlations showed that, for both sites, the infiltration ratio and wastewater flow have shown a good relationship with high correlation factor and that the calculation of wastewater flow was highly affected by monthly rainfall depth as well as number of rain days. From this result, it was concluded that the measurement of infiltration should be performed when the rainfall does not significantly affect the sewer flow. Also, it is notable that each value of calculated using method for infiltration evaluation are not comparable to each other, but independent methods. In selecting of evaluation method for infiltration, therefore, a great emphasis should be imposed to the character of area and the seasonal factor in order to select optimal one. It is desirable way for evaluating infiltration and reduction ratio using result from an optimal method.

This study conducted a survey on jean pants that targeted males in the 20s in order to select preferred brands for skinny jean pants. Preliminary data for the pattern development of skinny jean pants was presented through functionality evaluation, appearance evaluation and pattern analysis. The results were as follows. 1. The result of survey targeting males in the 20s to select the design and brand name of jean pants showed that skinny jean pants were selected as the most favorite type of jean pants to wear; in addition, non-brand products and brand names such as Uniqlo and Levi's were also preferred. 2. The result of functionality evaluation showed that L brand received a high score in all items except for items regarding the knee circumference and mid-thigh circumference, S brand received a high score as well as a low score, and N brand received a low score in general. The result of appearance evaluation showed that L brand for the waist height and waist circumference, N brand for the brand crotch circumference, posterior crotch length and knee circumference, and S brand and N brand for the length of pants were preferred. 3. The result of pattern measurements analysis from the result of functionality evaluation showed that L brand provided a large pattern measurement for the waist height, L brand provided less ease due to small pattern measurements for waist circumference; in addition, N brand for the knee circumference and mid-thigh circumference were preferred. 4. The analysis result shows that a ease of 5cm based on the belly band which is 3.5cm below the belt width is proper for the waist circumference when designing a skinny jean pant pattern and 4cm for the hip circumference and 32.5cm for the ease of crotch circumference are proper, -0.4-0cm for the ease of mid-thigh circumference and knee circumference in consideration of human body measurements; therefore, 80.1-80.5cm for inseam as the length from the crotch height to the leg length, 25.7cm for vertical hip length and 53.0cm for crotch length are proper.

This study aims to introduce missile live-fire during the ship operational test and evaluation(T&E) as a means of verifying the integrated combat capability(ICC) of various systems installed on naval ships. The research method identified domestic and foreign T&E systems and cases, and reports related to ICC, which were written during the ship's design stage. As a result of research, Republic of Korea is not conducting the missile live-fire at the ship T&E stage due to the lack of relevant systems, while the U.S. is conducting it based on the mission-based T&E and the end-to-end test system. As a way to improve within the current domestic ship acquisition systems, the reaction time analysis, a quantitative analysis result of ICC calculated at the ship basic design stage, was proposed to be verified by missile live-fire during ship operational T&E.

The purpose of this study is to compare student evaluation methods in team based learning classes for dental hygiene students. The subjects of this study were the score of dental hygiene students who took the courses of 'oral health education practice'. The analysis methods were spearman correlation analysis, skewness, kurtosis and Mann-Whitney U test. As a result, there was a significant correlation between the self-evaluation and peer-evaluation. Self-evaluation showed lenience tendency rather than peer-evaluation and self-evaluation found the highest central tendency. The peer-evaluation result was more lenience and more central in the group where self-evaluation was performed.
