This study investigated the development of a Korean version of the Ayurvedic constitution questionnaire and sought to verify its validity and reliability. Each study subject completed a self-administered questionnaire consisting of 63 questions. The Ayurvedic constitutions were placed into 7 categories. The results from 271 subjects revealed that the internal consistency reliability (Cronbach's ${\alpha}$) in the 41 item biometric signature part of the questionnaire was 0.757. The Cronbach's ${\alpha}$ for the 22 item psychological part was 0.616, whereas the Cronbach's ${\alpha}$ for the entire 63 items was 0.840. Taken together, the results indicate that the Korean version of the Ayurvedic questionnaire was valid. Within the questionnaire, the fourth item about body and the ninth item about psychological showed item-total correlations with negative total values, thereby indicating inconsistent (less reliable) responses. The remaining 61 items had a 0.864 degree of reliability. The results for the pure Vata Pitta and Kapha body types showed a high level of internal consistency reliability, presumably because those participants were of a pure constitution type. The Kappa factor for inter-item coincidence between the judgment of Ayurvedic constitution experts and the judgment derived from the written test scores was 0.619, thereby indicating questionnaire validity. The results of this study may be useful in further development of a Korean version of the Ayurveda constitution questionnaire.

The purpose of this study was to develop a self-report scale measuring dysfunctional communication behaviors that Korean husbands and wives may use during marital fights. Based on the four concepts of criticism, contempt, defensiveness, and stonewalling proposed by Gottman(1994a), an initial pool of 38 items was developed. Through expert reviews of the 38 items to assess content validity, preliminary 30 items were selected. Using a sample of 89 married couples who were living in Susan, Korea, we conducted item analyses and exploratory factor analyses with the 30 items. These analyses yielded a final 19-item, four-factor scale : criticism(5 items), contempt(5 items), defensiveness(5 items), and stonewalling(4 items). The internal consistency estimates for these subscales were satisfactory. Finally, using another sample of 228 wives, we conducted confirmatory factor analysis to confirm cross validity of the 19-item, four-factor model. The result indicated that this model fitted the data reasonably well. All standardized factor loadings were significant in this model. The results of this study supported reliability and validity of this scale.

Purpose: The purpose of this study was to develop a job stress scale for hospital-based home care nurses in Korea. The process was construction of the conceptual framework, development of the preliminary items, verification of the content validity, item analysis and test of the reliability. The preliminary items were based on literature review and in-depth interviews with home care nurses. As a result, eight categories and sixty items were selected. These were reviewed by seven specialists for content validity and finally fifty one items were chosen. Data was collected from 180 home care nurses who were engaged in 87 hospitals from August to September 2003. The result of item analysis one was excepted, The final item count was 50. Categories were as follows: overload work(8 items), lack of specialized knowledge and technique(5 items), ethical dilemma(4 items), role conflict(5 items), interpersonal relationships(6 items), visiting home environment(9 items), driving conditions(4 items) and lack of administrative support(9 items), The reliability of the scale by Cronbach's alpha was .948 and the domain's reliability ranged from .649 to .841. The result of this study could be used to measure the job stress of home care nurses. However, for further validity and reliability, repeated studies will be necessary.

For deciding the profitability and feasibility of the construction project, the schematic estimation has to not only link the design decision-making but also estimate the cost with reliability. The Object-based schematic estimation system was developed for easily linking with design-making and supports to evaluate the design alternatives in the design development stage but didn't consider the cost estimated by object supplementary and parameter work item. This research presents the Integrated Object-Parameter Schematic Estimation Model in the design development stage that can lead to more accurately estimate the cost through analyzing historical data from the high-storied office buildings. For the development of the proposed model for schematic estimation, after analyzing and classifying the work items from the Bills of Quantities(BOQs) and drawings of historical data, this research proposed the methods of estimating cost in accordance with attributes of each work item using regression analysis. In addition, a case study is performed for the effectiveness as comparing the proposed model with the previous estimating model.

This study was performed to provide the dress form for high school girls' clothing construction which can reflect the characteristics of their body. Two hundred and forty seven high school girls aged from 15 In 17 were directly measured. The results obtained from this study were as follows ; 1. High school girls' somatotype was similar to that of young adult women. They had the features of well developed upper trunk and well developed breadth, but less developed depth. 2. The correlation between length item and the other items was small enough to interpret that each item was independent. There was a Positive correlation between depth item and girth item. And, Observed correlation between weight and Rohrer's index and breadth, depth and girth item was much larger than expected, which showed that weight and Rohrer's index influenced on fatness factor. 3. Through factor analysis, six factors were extracted from anthropometric measurements. The first factor was representing upper body volumn which expressed the characteristics of somatotype better than any other factors, the second factor was breadth, the third factor was size, the fourth factor was length, the fifth was back shape and the sixth factor was shoulder shape. 4. For development of dress form for high school girls, directly anthoropometric measurements were used. The dress form constructed through this study represented the characteristics of high school girls, therefore this would be very useful to manufacture clothing for them in the future.
