  • The microarchitecture of trabecular bone plays a significant role in mechanical strength due to its load-bearing capability. However, the complexity of trabecular microarchitecture hinders the evaluation of its morphological characteristics. We therefore propose a new classification method based on static multiscale theory and dynamic finite element method (FEM) analysis to visualize a three-dimensional (3D) trabecular network for investigating the influence of trabecular microarchitecture on load-bearing capability. This method is applied to human vertebral trabecular bone images obtained by micro-computed tomography (micro-CT) through which primary trabecular bone is successfully visualized and extracted from a highly complicated microarchitecture. The morphological features were then analyzed by viewing the percolation of load pathways in the primary trabecular bone by using the stress wave propagation method analyzed under impact loading. We demonstrate that the present method is effective for describing the morphology of trabecular bone and has the potential for morphometric measurement applications.

  • Currently, SEAMCAT has been widely used as a tool to evaluate the effects of interference among wireless communication systems. In the previous work, we have incorporated the ITU-R P.526 pathloss model to the existing SEAMCAT in order to support the capability of interference evaluation taking into account any specific terrain characteristics. Along with this, we have implemented a terrain display function based on the Google map. However, the two-dimensional Google map based display is not effective in helping users to figure out some terrain features including the elevation variation in a given region. In order to alleviate this difficulty, we have incorporated the three-dimensional terrain display using the API of the Google earth to the existing SEAMCAT and provided the capability of viewing the positions of the associated communication systems, the variation of the carrier intensity and interference intensity in location, shadow region indication, and line-of-sight analysis and presented an example of interference evaluation.

  • The purpose of the study is to investigate the effects of physical attractiveness and dress on evaluation of female job Applicants in terms of suitable employment potential and job- type. The study was a 2$\times$3 between subject factorial design with two levels of attractiveness (attractive, moderately attractive) and three levels of dress image(masculine, androgynous, feminine). A group of clothing experts and the middle.level management staffs within a large corporation selected two models(attractive, moderately attractive) through two-step evaluation Process after viewing photographs of 50 female university students. Dresses in three levels were selected by a group of five experts. Two models were photographed with controlled background in three different clothes. Data were collected from 162 management level staffs enrolled in the Top Business Management, The Top Policy Science and the Top Press Information Graduated School of Korea University. Each respondent saw photograph and evaluated the applicant in terms of eight items of employment potential and suitable job type (management position vs. secretary) The results of this research were as follows: 1. Physical attractiveness had significant influences on applicants 'employment potential. Attractive applicant's emplolyment potential was evaluated higher than moderately attract live applicant. 2. Dress had little influence on female job applicants 'employment potential, but dress of androgynous image was evaluated relatively positively. 3. Physical attractiveness had some influences on the evaluation of suitable job-type. The attractive applicant was judged to fit in as a secretary and the moderately attractive model in management position.

  • The study considers viewpoints for qualitative improvement of landscape planning based on research literature, books and reports. By classifying items used in this study, evaluation criteria was derived for viewpoint selection using SPSS Statistics. In addition, we establish weights and prioritize viewpoints by measuring the relative importance within the hierarchical index. The analysis results are as follows: First, 16 viewpoints were determined using surveys from experts to establish specific and systematic plans for landscape simulation. Second, with respect to the medium classification level of viewpoint evaluation, the most important factor found was 'view' followed by 'publicness' and 'place.' Third, priority by viewpoint was found to exhibit the following order of relative importance: visual openness of viewpoint, favorability as view target, cultural property space, historicity, public place, gateway place, area where the target can be observed, thickly-populated or most-used place, place where various shapes of targets and surrounding landscape can be identified, ecological protection area, river and waterside area, viewing angle (relief-etching), viewing direction, major roads, distance between the viewpoint and the target, and plains and farmland. These results can contribute to developing systematic and reliable analysis frame for qualitative improvement of landscape planning and evaluating landscape simulation.

  • This study examines the spatial compositions of children's reading rooms, furniture characteristics, and users' satisfaction levels for the furniture in public libraries. Field measurements and surveys were performed in 5 public libraries. Results imply that the spatial compositions of reading rooms in libraries were classified into three categories according to the locations of bookshelves and reading space. Management areas should not be located at the edge of reading rooms but be located at the center of reading rooms to avoid clerks' narrow viewing angle toward young kids and to ensure security for the kids. The evaluation for bookshelves according to evaluation checklists was acceptable, but users were not always satisfied with the bookshelves due to the inappropriate positions of books in shelves. The evaluation for desks was generally acceptable according to the checklists and users were satisfied with them. In general, the desk with higher scores by the checklist provided better satisfaction to users. However, the score by checklist for chair and user satisfaction were not always similar each other. Convenience areas in reading rooms were not enough compared to bookshelf, reading and management area. Computer tables that were designed in a way that users sit down and use the computers were highly preferred.

  • Existing outdoor lighting evaluation methods for the city beautification at night, the measurements are limited by one point to analyze the photometric data. However, this methods could not represent the diversity of photometric result from the distance. This study aims to propose the new outdoor lighting evaluation method of structure surface luminance in accordance with the measuring distance. For the purpose, the field measurement and simulation of an illuminated structure were conducted by CS-100, Digital Photometry Instrument ProMetric 1400, and the Lightscape v 3.2 from the distance of 100[m], 300[m], 500[m]. The result shows that evaluation of the surface luminance by the distance should be measured from about 100[m] of an illuminated object for getting the familiar result from computer simulation.

  • To plan more effective exhibitions, exhibitions should be evaluated and verified through research. This is Important in that it will present measures for improving shortcomings in exhibition goals and procedures; and it will also provide new ideas and goals for future exhibition plans. The purposes of this study are to investigate the applicability of evaluation methods by organizing related theories systematically through a literature review and to provide more practical and valuable information about the methods by applying them to actual museums. For this study, the National Science Museum was investigated since it uses various themes and exhibition methods, compared with other science museums. Exhibition structures and presentation formats were first analyzed, and then the methods of trace and observation were used to investigate how visitors use the museum. Surveys were also conducted at two different times. The results of the analyses showed that problems of exhibits, arrangement methods of exhibition space, or guide systems are more prominent than those of the presentation format itself. Based on these results, measures for improvement are suggested as follows: First, new formats of exhibition halls using new window frames or holes should be explored to stimulate visitors' curiosity and to lead viewing traffic flow in the museum. Second, in presenting representative exhibits, a gate can be installed at each exhibition area, and representative exhibits are displayed by the gate or between exhibition booths. Third, if a small space is provided at the end of each exhibition area, it can be used to give an orientation on the next exhibition or used as a resting place.

  • Due to the expense of health care and the need to contain costs, many stroke patients are discharged from hospitals while still in an impaired condition. Using Tele-rehabilitation, these patients can receive rehabilitation services remotely. A pegboard is a conventional rehabilitation therapeutic device that integrates cognition, sensation and hand motor function. This study proposes a Tele-rehabilitation content with automated pegboard and shows its functional feasibility. The evaluation of the pegboard session was automated with RFID (radio frequency identification), and a 16-hole pegboard was rapid-prototyped. After a pegboard session is completed, the session result is uploaded to a server automatically for viewing on a web browser by a remote therapist. The therapist can also send messages to remote patients to encourage them or to manage the rehabilitation process.

  • The subject of this study is user experience analysis for OTT mobile app services. Application service quality was quantitatively measured by utilizing KS-eSQI evaluation model from a service quality perspective. The purpose of this analysis is to analyze how service reuse and other people's intention to recommend services are affected by service quality. In addition, further analysis of user experience will qualitatively look at what efforts are needed to improve OTT service quality and provide a user-friendly environment. According to the survey, the higher the level of KS-eSQI service quality, the higher the reuse of OTT services and recommendation of others. In particular, the dimensions of primary services and unexpected additional services had a higher impact on customer loyalty and recommendation of others than in other industries. Moreover, the following three implications were found to improve app services from a customer experience perspective. First, images and video thumbnails that highlight the strength of the content they provide should be actively utilized. Second, it is necessary to provide service companies with evidence for data-based work recommendations. Third, it should provide a viewing environment in which users can respond more intelligently to the various situations and conditions when they actually watch.
