The objectives of this study were to investigate appearance management behaviors and hairstyle preferences in accordance with personality types and self-image, and to examine the characteristics that influence simultaneously the appearance management behaviors. A survey was used for as for this research. The personality properties of introversion and extroversion were further divided, based on the aspects of emotions, thoughts, behaviors, and interpersonal psychological functions. The subjects were 383 girls in their first year of high school in Seoul. The extrovert type showed a higher level of management for clothing, hair and face than the introvert type. The emotional extrovert type and the interpersonal extrovert type showed the highest level of clothing management, the active extrovert type showed the highest level of face management, and the interpersonal introvert type showed a very low level of hail management. The high school girls who had a higher social and mature self-image showed a higher level of clothing, hair and face management. Introverted girls preferred a mid-length straight hairstyle more than extroverted girls. The higher the social and mature self-images girls had, the more they preferred a long wave hairstyle. The higher the cute image they had, the more they preferred wave hairstyle. The entire appearance management behavior was affected significantly by extroversion, mature image, and allowance, simultaneously.

The application of knowledge management concepts as a way to improve project success is an emerging topic for project management researches around the world. The Construction Extension to the PMBOK^® Guide Third Edition documents the knowledge and practices that are generally recognized as good practices for managing engineering and construction projects. However, it is not unusual to see that engineering and construction projects suffer from poor performance. Based on a critical literature review, a theoretical framework is developed for the application of knowledge management in engineering and construction projects. This framework is subsequently applied as a lens to examine the construction extension to the PMBOK^® Guide, aiming to identify the key characteristics of knowledge management in this standard. This research also aims to highlight those aspects of the construction extension to the PMBOK^® Guide that can be improved from the knowledge management perspective. Recommendations are made to improve this standard by means of applying knowledge management concept so that better project outcomes can be achieved.

The aim of the current study is to examine the effects of mothers' home management ability on school-aged children's time and life management skills through the mediation effect of children's self-regulation. Study subjects were 317 5- and 6-grade children at elementary schools located in Seoul and Gyeonggi area and their 317 mothers. The findings were as follows. First, in the SEM model of predicting children's time management skill, greater mothers' home management ability significantly predicted better time management skills among their children. Second, mothers' home management ability also indirectly affected children's time management skill through its significant effects on children's self-regulation. The test yielded a significantly mediation effect of self-regulation. Children's self-regualtion was strongly related to time management skills. Third, in the SEM model predicting children's life management skills, maternal ability of home management again directly predicted greater life management skills of their children. However, mediation of self-regulation was not statistically significant. The findings suggested the important role of mothers' home management ability in instilling and modeling self-regulation and self-management skills of school-aged children.

3세대 이동통신 방식인 WCDMA가 상용화됨에 따라 국내에서도 GSM 방식의 SIM 카드의 역할을 하는 USIM(Universal Subscriber identity Module) 카드가 본격적으로 도입되었다. USIM 카드는 WCDMA 단말기에 필수적으로 장착되며, 기존의 SIM 카드의 기본적인 기능 이외에도 다양한 기능이 추가될 수 있다. 본 논문에서는 자바카드의 구조 및 보안적 특징, USIM의 보안 요구사항 및 자바카드를 위한 USIM 아키텍쳐에 대해 설명한 후에 USIM의 다양한 활용을 위한 보안 고려사항에 대하여 논의한다.

Efficient financial management is a critical factor in achieving school foodservice goals. The objective of this study was to suggest efficient financial management practices in secondary school foodservices. In pursuit of this objective, we first identified performance indexes for measuring the success of financial management. Second, we suggested financial management standards, financial data classification methods and a report system. Last, we analyzed operating ratios with the financial data of self-operated and contract-managed school food services. The data were collected through an open-ended questionnaire from 10 middle/high school foodservices in Seoul and Kyeonggi Provincial during on-sites visits and interviews with dieticians and managers. Student participation, sales goals, re-contract frequency and number and cost of disaster loss were identified as the performance indexes for financial management. Income statements were compiled by identifying and classifying financial data. Total revenues consisted of subsidies, meal sales, other revenue and interest. Expenditures consisted of purchased food, salaries and wages, utility costs, office supplies, kitchen supplies, purchased services, company overhead indirect costs, facility investment and maintenance, facility usage expenses, employee benefits and miscellaneous. Mean price of a meal was 2,326 won at self-operated foodservices when the subsidies were included as revenues and 2,360 won at contract-managed foodservices. When including the subsidies as revenues, the operating ratios of self-operated foodservice showed that the food cost percentage was 66.9％, labor cost 23.2％, operation cost 9.9％ and profit 0％. The correspond figures at contract-managed foodservices were 57.6％, 21.5％, 15.3％, and 5.5％, respectively. Food costs in self-operated foodservices was significantly higher than that for contract-managed foodservices, however, facility investment and maintenance and facility usage expenses at self-operated foodservices was significantly lower than those for contract-managed foodservices. Based on this study, the methodology and classification system of financial data was found to be applicable to assess the financial structure of school foodservices.

The purpose of this study was to identify the relationship between the levels of foodservice management activities and job satisfaction of the dietitians in elementary schools. Out of 130 questionnaires distributed to elementary school dietitians in Incheon, 127 were returned and analyzed ($98\%$ response rate). The questionnaire included two multiple-item scales for measuring foodservice management activities and job satisfaction, respectively. All the items in the scales were coded 1 to 5 for 'certainly no', 'no', 'neutral', 'yes', and 'certainly yes' and grouped by using factor analyses. Most of the responding dietitians were working for schools in urban areas and have independently managed on-site kitchens. The 19 items on food service management activities were grouped into 6 factors and the mean scores of the levels of Personnel Hygiene Management, Education & Training, Sanitation & Safety Management, Menu Quality Management, Service Management, and Environment Management were 4.76, 4.26, 4.24,4. 05, 3.61 and 3.39, respectively. The 23 items on job satisfaction were grouped into 4 factors and the mean scores of the satisfaction levels of Systematic Environment, Job Duty, Job Condition, and Physical Environment were 3.38, 2.83, 2.53, and 2.08, respectively. Overall, the levels of food service management activities and job satisfaction were positively associated with a correlation coefficient of 0.254 (p > 0.01). In particular, satisfaction levels on job duty itself and systematic environment were positively associated with the levels of overall management activities. The results suggest that improving dietitians' job satisfaction could increase the levels of management activities of school foodservice dietitians, resulting in quality improvement of school food service.
