The apartment buildings now covers more than 50% of the total residential types in Korea and the urban residential area becomes increasingly congested with newly constructed high-rise apartment buildings. Judicial precedents require, for securing the solar rights in the residential area, that the consecutive sunshine duration should be at least two hours from 9:00 to 15:00 or the accumulative sunshine duration should be at least four hours from 8:00 to 16:00 as of the winter solstice. Disputes are increasing, however, on infringed solar rights and view rights for the neighboring structures as cases occur where the requirement cannot be satisfied in congested residential areas. The sunshine duration scan be assessed by measuring it on the site of the dispute, but it is impracticable to actually measure it for every case on the winter solstice, only one day out of the whole year. At a trial, therefore, 3D computer simulation is used to calculate the sunshine duration and determine the extent of infringement for submission of the evaluation to be used as the basis of the judgment. The simulation, however, may have an error in its result up to the program characteristics and the accuracy of the input data such as the structure shape and height, the distance between structures, and the ground level. This study, therefore, used a self-developed VIEW program with Autodesk VIZ 2006 to provide a simulation method for solar access evaluation, and verified its efficacy by comparing the results with the actual measurements.

The objectives of this study were 1) to classify survey respondents according to vanity scales, and 2) to identify price attitude among the classified groups. The participants were 276 university students who were residents in Seoul. Data were analyzed by factor analysis, cluster analysis, and one-way ANOVA. The vanity scales consisted of four factors; physical concern, physical view, achievement concern and achievement view. Based on these four factors, the respondents were classified into three clusters(interested, vain, and self-confident) as an attached group name. There were significant differences in the dimensions of materialism, price attitude and store choice behavior among the clusters. Marketing implications are discussed.

Optimal Power Flow (OPF) is an important operational and planning problem in minimizing the chosen objective functions of the power systems. The recent developments in power electronics have enabled introduction of dc links in the AC power systems with a view of making the operation more flexible, secure and economical. This paper formulates a new OPF to embrace dc link equations and presents a heuristic optimization technique, inspired by the behavior of fireflies, for solving the problem. The solution process involves AC/DC power flow and uses a self adaptive technique so as to avoid landing at the suboptimal solutions. It presents simulation results of IEEE test systems with a view of demonstrating its effectiveness.

This study developed evaluation indicators for the comfort experience of virtual reality (VR) headsets by classifying, defining, and weighting cybersickness-causing factors using the Delphi research method and analytic hierarchical process (AHP) approach. Four surveys were conducted with 20 experts on VR motion sickness. The expert surveys involved the 1) classification and definition of cybersickness-causing dimensions, classification of sub-factors for each dimension, and selection of evaluation indicators, 2) self-reassessment of the results of each step, 3) validity revaluation, and 4) final weighting calculation. Based on the surveys, the evaluation indicators for the comfort experience of VR headsets were classified into eight sub-factors: field of view (FoV)-device FoV, latency-device latency, framerate-device framerate, V-sync-device V-sync, rig-camera angle view, rig-no-parallax point, resolution-device resolution, and resolution-pixels per inch (PPI). A total of six dimensions and eight sub-factors were identified; sub-factor-based evaluation indicators were also developed.

The purpose of this study was to identify the relationship between self-empowerment and a existential spiritual well-being in pregnant women, and to provide the basic data for nursing intervention. The subjects were 182 women who visited 2 OBGY hospitals in Taegu, Korea and ranged in age from 21 to 40. The data was collected during the period from May 6th toMay 24th, 2002. The instruments were the revised existential spiritual well-being scale developed by Paloutzian and Ellison(1982). Originally the instruments were developed by Spreitzer(1995) and Jung Hea Joo(1998), who translated it into Korean. The data was analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression. The results of this study were as follows : 1. Mean score of total empowerment was 3.72 and the subcategory 'meaning', had the highest score at 4.15. 2. Mean score of existential spiritual well- being was 4.16. 3. Existential spiritual well-being was positively related to self-empowerment (r=.400, P=000). 4. A significant statistical difference between education, religion and self-empowerment was found. 5. A significant statistical difference between hope of pregnancy and a existential spiritual well-being was found. 6. The most important variable affecting the existential spiritual well-being was meaning which accounted for 15% of the total variance in stepwise multiple regression analysed. Three variables, competence and hope of pregnancy accounted for 22% in existential spiritual well-being. From the results of the study, the following recommendations are presented : 1) Indeed, we should identify existential spiritual well-being for real meaning of spiritual well-being in future. 2) It is required to check the effect of existential spiritual well-being and self-empowerment through the repeated studies. 3) We need to take a serious view of the meaning affecting existential spiritual well-being in pregnant women.
