In this study, the effect of augmented reality subtitle content on users was investigated by using a subjective evaluation method and a statistical approach. The human factor was defined as subtitle position and font size. Then, we analyzed the effects of the defined factors on human eye comfort and visibility. Ten participants conducted related survey evaluation tasks with a 1-minute break after viewing the content for 3 minutes.

Previous studies have shown that the ex-ante financial ratios, mainly used by financial institutions for loan evaluation purpose, are related to the ex-post finn's performance of venture firm's. The main objective of this study is to examine whether non-financial variables such as 'technology', 'marketability', and 'other business indexes' have extra explanatory power in forecasting the ex-post firm's performance of small and medium size venture firm's in Korea. The implications and results of this study are expected to be useful in loan evaluation, investment decision and internal management decisions of venture firms. Among small and medium sized manufacturing firms funded in the year of 1999 through 2005, 416 firms are selected for our analysis. The relationship between evaluation indexes and firm's success/failure is investigated using binary logistic regression analysis and factor analysis with an aid of SPSS program. The summarized results are as follows. First, current evaluation model, used for loan evaluation purpose for small and medium size manufacturing firms show the same discriminatory power as previous prediction model. Second, among the tested additional variables, significant indices are 'technological capability of CEO', 'managerial capability of CEO', and 'business feasibility'. Third, while previous studies on evaluation structure had 3 factors, this study showed that valuation's structure has 6 factors.

As the user demand for power plants becomes various, design objective becomes complicated. To review the system feasibility, system objective and evaluation criteria need to be newly defined. In this study, engineering design procedure of the multi-purpose power plant, such as barge-mounted combined cycle power plant with $CO_2$ capture, was shown as a previous work for the feasibility review of the system alternatives. For the system design, heat and mass balance for each system configuration was firstly performed. Using the thermal analysis results, conceptual design of system alternatives was carried out. And then, preliminary design of the major equipment was done. The engineering calculation results of this study would be used as the evaluation data for system feasibility review.

The purpose of this study is to perform the post occupancy evaluation in apartment housing with the dining room and kitchen(DK) facing the front side, and then to compare them with findings in unit plan facing the back side. A questionnaire survey method was used in this study. These questionnaires were administered, along with an interview, of 200 households in the apartment of 27-28 pyoung($76.50-78.54\textrm{m}^2$), in Gwangju city. Those living in an apartment with DK facing the front side tend to be less satisfied with the physical feature factors. expecially for layout of rooms, location of second bedroom and master bedroom, size and location of storage spaces, and location and size of balcony than those with the DK facing the back side.

The purpose of this study is to suggest a basic data of playground design that can arouse various curiosities and interests of children. The 13play areas 'A' kindergartem's playground that parent, music, play equipment, soccer field, water, sand, tunnel, maze, animal, plant, ground hill, bike road, and inner court were evaluated by 16 teachers and 165 children between the age of 4 and 5. POE data of teachers were collected by questionnaire. And children chose and rated very fun and interesting 5 play areas of 13 ones based on the photos. The results were as following. 1) 13 play areas were generally used evenly with diverse purpose. 2) the environment of the play areas was deemed very appropriate. 3) maze area and play equipment area were recognized as the most favored play areas by children. 4) teachers recommended soccer field, plants, maze, tunnel, music area as the most favorable play areas.

The performance of full-scale steel and composite bridge safety barriers under vehicle crash is evaluated by using the nonlinear explicit finite element code LS-DYNA. Two types of vehicles used in this study are passenger car and truck, and the performance criteria considered include structural strength and deformation, occupant protection, and post-crash vehicle behavior. It can be concluded that the composite safety barrier satisfies all performance criteria of vehicle crash. Although the steel safety barrier satisfies the performance criteria of occupant protection and post-crash vehicle behavior, it fails to satisfy the performance criterion of deformation. In all performance evaluations, the composite safety barrier exhibits a superior performance in comparing with the steel safety barrier.

In damage investigation of building structures suffering from earthquake, estimation of residual seismic capacity is essential in order to access the safety of the building against aftershocks and to judge the necessity of repair and restoration. It has been proposed that an evaluation method for post-earthquake seismic capacity of reinforced concrete buildings based. on the residual energy dissipation capacity (the residual seismic capacity ratio )in lateral force-displacement curve of structural members. The proposed method was adopted in the Japanese 'Damage Level Classification Standard' revised in 200l. To evaluate the residual seismic capacity of RC column, experimental tests with positive and negative cyclic loading was carried out using RC building column specimen. Parameters used by the experiment are deformability and member proportion. From the test results, it is appropriated that the residual seismic capacity of RC buildings damaged by earthquakes is evaluated using the method in the Guideline.

This study was conducted to develop and apply a computer-based multimedia nutrition education program for preschoolers based on the Dick and Carey model of instructional design. The Dick and Carey model included 4 phases: analysis, design, development, and evaluation. The program's instructional goals, objectives, assessment instruments, content, examples, and practice questions with feedback were written in the design phase. To be familiar with the 5 food groups, 'Nutrition exploration' were programmed using Hyperstudio. 'Nutrition exploration' was designed as a five-session, interactive multimedia game, with each session taking about 5 minutes to complete. Nineteen preschoolers, aged 6, volunteered to participate formative evaluation. The effectiveness of the program was examined using a pre-post test design. Participants were recruited by personal contact at the individual preschool education center. The application was carried out during 4 weeks. The results showed that intervention participants significantly increased knowledge between pre-test and post-test. The results support using IMM (interactive multimedia) to disseminate nutrition education to the target population. This research provides the basis for continuing development of computer-based nutrition education materials.

This study aimed to provide basic data for the national park management by analysing visitors' behavior and satisfaction determinants by importance-performance analysis and estimated regression analysis through post-occupancy evaluation questionnaire method to the Gyeongju National Park visitors. It was found that facilities and use management according to place and use group, the diversity of visit program, high quality of guidance and hospitality of staffs and conservation of historic and landscape resources for Gyeongju National Park were necessary as the results of behavior analysis, importance-performance analysis. The historic landscape resources, hospitality of staffs, visit road and safety facilities, commercial facilities were important determinants of users' satisfaction as the results of regression analysis. It suggested the characteristics of Gyeongju National Park and these factors were the most important factors for the improved management.
