This study has been designed to develop a health behavior scale. Data were collected through a survey over a period of two month period. Subjects who participated in the study were 298 Korean adults. The author used a convenience sampling method. The analysis of the data was done with SPSS PC for descriptive statistics and factor analysis. Initially 34 items were generated from the interview data of twenty one adults and from literature review and survey. This preliminary scale was analyzed for a reliability and validity. The results are as follow : 1. Crombach Coefficient alpha for the 30 items was .7907. 2. Factor analysis was done in order to confirm construct validity and nine factor were extracted from the results. These contributed 54.4% of the variance in the total score. 3. Nine factor label were 'exercise' 'stress management' 'energy conservation' 'limit in liking' 'selection of food' 'ingestion of natural food' 'health examination' 'relaxation' and 'nutrition'. The author suggests that this scale could be adequately applied in assessing the health behavior of Korean adults. The results of using this scale in a study can contribute to designing an appropriate health promotion strategy.

Internet has become an important part of teenagers' life and has changed the life style of teenagers. Internet can be an useful tool for educating teenagers and also can be misused as a cyberspace for social problems. Recognizing that teenagers spend most of their free time enjoying internet and they form their own new life culture, it is needed to develop practical strategies for maximizing the positive effect of internet on the teenagers' culture. The purpose of this research is to suggest a desirable way for forming teenagers' healthy internet-based culture. The research was conducted by the survey of teenagers in the city of Pyongtaek on their use of internet and their problems The survey shows that most of teenagers are using internet in order to release the stress and most of them are hooked on it. It also indicates that cyber police and volunteer groups should be formed to help the desirable teenagers' internet-based culture.

The purpose of this study is (1) to demonstrate that ignoring group differences may mislead to incorrect conclusion when analyzing correlation data (e.g., factor analysis), (2) to highlight the importance of the data analytic method considering group differences, and (3) to provide ways of incorporating group differences in data analysis. In study, 1, ignoring group difference in factor analysis may mislead to incorrect factor structure. To remedy this, z-transform method and group analysis tool in covariance structure models were suggested. In study 2, the group differences effect was illustrated by using real data (IQ test data).

Purpose: The purpose of this study was to explore the essential contents of mobile application for self-management of patients with osteoarthritis through Delphi survey. Methods: The Delphi survey was conducted with 14 experts to determine the importance of contents in osteoarthritis self-management mobile application. Results: A total of 25 contents were finalized for the osteoarthritis self-management mobile application. The contents consisted of 7 items for daily living management, 8 items for disease information, 3 items for pain management, 6 items for exercise, and 1 item for weight management. Conclusion: Based on the results of this study, self-management mobile application can be developed and used as an interventional tool for patients with osteoarthritis.

This study purports to investigate the status quo of the environmentally-friendly green healthcare in teaching hospitals through the questionnaire survey. Data were collected from a total of 46 hospitals. The survey results revealed that most teaching hospitals did not meet the global standard of environmentally-friendly green hospitals. Especially, such items as alternative energy system, water recycling, CO2 emission reduction, green building construction, installation of pond or spring were found to be significantly below global standard. Based upon the study results, various strategies for establishing green hospitals were discussed. For example, energy saving design, such as solar heating, natural wind cooling, automatic temperature controller, green material use, wall surrounded by ivy, were recommended. In conclusion, the strategy and evaluation tool developed in the study will provide a good guide for establishing environmentally-friendly green hospitals.

Aerial videography techniques have been used to inventory conditions associated with grassland, forests, and agricultural crop production. Most recently, aerial videography has been used to verity satellite image classifications as part of the natural ecosystem survey. The objectives of this study were: (1) to use aerial video images of the study area, one part of Taean Seashore National Park, for the accuracy assessment, and (2) to determine the suitability of aerial videography as an accuracy assessment, of the land cover classification with Landsat-TM data. Video images were collected twice, summer and winter seasons, and divided into two kinds of images, wide angle and narrow angle images. Accuracy assessment methods include the calculation of the error matrix, the overall accuracy and kappa coefficient of agreement. This study indicates that aerial videography is an effective tool for accuracy assessment of the satellite image classifications of which features are relatively large and continuous. And it would be possible to overcome the limits of the present natural ecosystem survey method.

This study in an attempt to analyze the child's readiness for school and to pursue the facts that influence the readiness. the child's readinees for school was analyze on the developmental tasks in terms of physical, intellectual, social and moral development of first graders. On the facts that influence the readiness, age, sex, home environment and preschool experiences were surveyed. Ⅰ. Objectives 1. To survey the actual developmental conditions of physical, intellectual, social, and moral development of first graders. 2. To analyze the differences of school readiness in of sex, age and birth order. 3. To analyze the influence of home environment and preschool experience upon readiness. 4. To survey the differences of evaluation between parents and teachers on achievements of readiness. Ⅱ. Method 1. subjects were 848 mothers of primary school first graders and 20 primary school teachers. By the stratifeed sampling method, Seoul city was divided into three types of districts. 2. measurement tool was the check test for the child's readiness for school.

According to Department of labor guideline "2012-104 (2012.9.26.)" This study is to suggest the basic information and the improvement for the application of risk assessment on a construction site by group interview & survey of construction worker who is the practice of the subject and then numerical analysis about awareness and action plan of Safety and health. The result of group interview and survey of construction worker, most of construction worker feel the danger during the work. Then construction worker analysis results that risk assessment helps to change & raise awareness of safety and reduce an industrial disaster. Easy Safety management activity such as TBM & safety education active will be necessary for safe worksite and then I suggest the TBT(tool box talk) active which combines TBM & safety education.

A gravitational weak-lensing map provides a weighted "picture" of the projected surface mass density and is to be an important tool for identifying "mass-selected" clusters of galaxies. However, weak-lensing maps have a limitation due to the projection of large-sclae structure along the line-of-sight. Geller et al. (2010) and Kurtz et al. (2012) compared massive clusters identified in a dense redshift survey with significant weak-lensing map convergence peaks. Both assessments of the efficiency of weak-lensing map for cluster identification did not draw a general conclusion, because the sample is so small. Thus, we additionally perform deep imaging observations of fields in a dense galaxy redshift survey that contain galaxy clusters at z~0.2-0.5, using CFHT Megacam. Our study will provide an important opportunity to examine the efficiency and completeness of a weak-lensing selection, and further to improve the method of cluster identification in future weak-lensing surveys.
