Background and Purpose: Indigenous people who leave their hometowns and move to the city to earn a living became urban aboriginals. During the process of adapting to urban living situations, they may use various coping strategies such as smoking to overcome their stress. Therefore, it is crucial to provide health education including smoking prevention, increasing knowledge regarding of tobacco hazard, self-efficacy of anti-smoking, and adjusting smoking behavior so as to empower their anti-smoking motivation to prevent lung cancer. The purpose of this study was to explore the effectiveness of an anti-smoking program on urban aboriginals in Taiwan. Methods: A quasi-experimental study design with purposeful sampling was employed. A total of 125 aboriginal subjects were recruited from two local churches at Shu Lin area in northern Taiwan. Subjects were divided into an experimental group (n =64 ) and a control group (n = 61). Both took pre-tests in order to set baseline values, and only the experimental group participated for 3-weeks in the anti-smoking program classes. Both groups took post-tests immediately after the intervention in order to evaluate the immediate effects of the teaching program, and a follow-up test was conducted four weeks after the intervention. Data were analyzed using descriptive statistics, one-way ANCOVA, and repeat measure ANCOVA. Results: After controlling for confounding variables, the results showed that there were statistically significant differences in the self-efficacy of anti-smoking and smoking behavior between experimental and control groups in the immediately post-test and the follow-up test (p < 0.05). However, there was no significant differences in the recognition of hazards of smoking at eiter time point. Conclusions and Implications for Practice: The findings of this study revealed that the anti-smoking program effectively improved self-efficacy of anti-smoking, and decreased the smoking behavior in urban aboriginals. They provide useful information as a reference regarding of aboriginal health promotion to health providers. It is imperative that anti-smoking be reinforced for those regular smokers to prevent induction of lung cancer.

This paper introduces Database security to prevent the rapidly increasing issue of private information leakage. The Database security examined in the paper separates into DB access control area and DB encryption area which further leads the paper to analyze the factors of the two areas and suggest necessary elements for creating stable Database security. In addition, the paper examines previous DB security programs by areas and analyzes pros and cons from the tested result. The experiment indicated that while DB access control presents less degradation and reduced the need to modify the existing DBMS since the access control operates at the end point of the network, DB encryption presented strength in protecting the data from unauthorized access. On the other hand, DB access control is less useful in preventing the attack in advance which leaves the log to enable tracking afterward while DB encryption can only be operated by limited types of Database and causes degradation due to system load and shows higher percentage of failure when creating the system. This paper examines characteristics of Database security areas in order to be used as a reference for institutions or companies seeking stable Database security.

The objective of this study is to find out the professionalism of secondary school teachers in teaching environmental subjects. This research was conducted using a questionnaire survey of 431 secondary school teachers from 34 schools in Seoul and Gyeonggi Province, Korea. A 5-point Likert scale self-evaluation questionnaire on their professionalism in environmental education was developed based on Hungerford et al.'s (1994) evaluation criteria. Two middle school teachers' classes were observed, and video taping and interviewing were also conducted. The survey analysis revealed that teachers evaluated their professionalism on environmental subjects to be a little above the middle of the scale. The mean values were 2.80 for the foundation level; 2.86 for the conceptual awareness level; 2.84 for the investigation level; 2.94 for the environmental action skills level; and 2.84 for the educational application level. However, class observations revealed that there was some gap between their self-evaluation of professionalism and their actual classroom application. Both classes were not that satisfactory with regard to 'the abilities to communicate and apply ecological concepts', 'the ability to clarify the roles of different value systems for environmental issues and personal values in decision making', 'the ability to clarify their own value system regarding solutions to environmental issues', and 'the ability to apply citizen action skills for solving environmental issues and for sustainable development'. The results provide a basic reference for the improvement of environmental-related education.

The objective of this study was to introduce the current status and development strategy for the environmental restoration of stream side in Japan, and to consider the methodology which could be effectively applied to the environmental restoration of stream side in Korea. 1. We should establish a new paradigm of forest conservation and erosion control which can emphasize the restoration of the stream side ecosystem and reduce soil movement in the areas. Also, in the past, the objective of forest conservation and erosion control was to fix soil by constructing permanent structures. The direction of future forest conservation and erosion control needs to be new forest conservation and erosion control technology to prevent large scale soil movement but allow small scale soil movement to conserve sound ecosystem and biotic habitats. 2. In the past, the goal of forest conservation and erosion control planning was to fix the amount of soil movement by constructing permanent facilities. Forest conservation and erosion control planning in the future needs to change the techniques which could prevent soil movement from large scale of soil disasters, but allow soil movement effectively to a small and middle scale's soil movement. Also, it is considered to change erosion control dams from non passing type to passing type. 3. In the point of ecological conservation aspects, we should evaluate the effects of new forest conservation and erosion control methods which are emphasized on the restoration of the stream side ecosystem. Also, forest conservation and erosion control construction projects for restoring stream and river ecosystem should be planned for perfectly restorating their ecosystems by the way of sustainable maintenance and management. 4. The restoration direction of stream and river ecosystems needs to be restoring the diversity of small geographies such as waterway, shoal and puddles rather than flattening stream bed. And the restoration of the stream side ecosystem should provide continuity of the stream side environment which allows desirable biological habitats, and environmentally sound facilities to harmonize with the environment.

This research aims for suggesting the significance and approaching method of historical study in health law in light of its historical progress and fundamental understanding of jurisprudential method. Historical research method of health law primarily targets to investigate the changes of the law in historical circumstances. In a further practical view point, however, the purpose of the study is to understand the 'current' system of health law appropriately. In addition, historical study enables us to recognize the fact that many systems related to health law are connected and interactive. The study can even function as an important reference when designing future health law system. Therefore, health law researchers have to investigate ideological, philosophical, political, economic, or social reasons of why such rules were legislated beyond a mere confirmation of past forms of the health law system. In other words, it is not only important to understand the provisions of past health law but also to examine how the regulations have formed, how they established the regulatory power in reality. Identifying how the rule of law had been executed in the reality of law is also a crucial part of historical study.

This study aims to examine the effects of art therapy on challenging behavior of schoolchildren. For this purpose, I selected one class of 4th year student of S primary school, located at Jeongeup city, Jeonlabukdo, and selected 4 study subjects through examination of K-CBCL children. juvenile behavior evaluation scale, characters, school life and K - HTP test. With regard to procedure of this study, I carried out art therapy program at the art class for 60 minutes one time a week for 4 months, a total of 17 sessions from Apr. 3, 2007 to July 24, 2007. I made this program with some modification in reference to Arts Therapy Technique (Counpia Remote Training Center, 2005), Group Art Therapy (Choi Seon Nam. Kim Gap Sook. Jeon Jong Kuk, 2007) and the Effects of Peer Group Art Activity on Sociality Skill of Offensive Children (Park Ju Yeon. Lee Byeon In, 2005). For each child, I compared and analyzed the changes in score of K-CBCL children. juvenile behavior evaluation scale, behavior by K-HTP (dynamic house-wood-human figure test) analysis and by school life(KSD) image analysis before and after treatment. I also carried out qualitative analysis on behavioral feature of each child for each session. This study obtained the following conclusions. First, child A showed positive change in comparison before and after art treatment program of score K-CBCL children. juvenile behavior evaluation, K-HTP image test and school life. Since he was so active and wanted to obtain good evaluation from anyone that he frequently had quarrel with friends, spoke against others well and beaten others much but was changed and did not speak against others or beat. Second, child B showed clear difference in comparison before and after art treatment program of score K-CBCL children. juvenile behavior evaluation, but no significant difference in K-HTP image test and school life. However, I observed substantial changes. While he could not speak frankly to others, felt empty in mind and was offensive in personal relations, he was changed, did not have quarrel with others or speak against others that much and improved his relationship with friends or teachers. Third, child C showed positive change in score of K-CBCL children juvenile behavior evaluation after art therapy program. In comparison of K-HTP image test and school life treatment before and after treatment, he still longed for mothers in mind but found rather stable after treatment. Fourth, child D showed positive chance in score of K-CBCL children. juvenile behavior evaluation scale after art therapy program, but almost no changes in K-HTP image test. But he depicted good relationship and socializing with other friends in school life. While he could not carry his point due to social immaturity and felt depressed, he got more confident. This result of study showed that art therapy had positive effects on correction of schoolchildren.

In this paper, in order to exclude the expansion of M/W relay frequency or its new frequency assignment possibly, we analyzed a possibility of substituting M/W system by B-WLL or optical fiber network regarding service quality and economical points. To define the target of service quality, pre-condition and analysis method for the selected media have been derived to compare each other. E1 transmission with BER 10$^{-1}$ was chosen as a reference capacity, and service distance was calculated f3r the selected media as a function of availability. Also from the economical point we considered 3 systems such as optical fiber, M/W, and B-WLL based upon basic system structure, and analyzed them for various line configurations of fiber optic and B-WLL according to service period, system capacity, transmission distance, and data rate. It was confirmed that B-WLL can provide quality of service with 99.999 % availability within 1.6 km cell radius, and for optical fiber substitution, the leased fiber conduit on an electric pole is more economical than M/W system irrespective of service period, but in case of directly digging for underground conduit, it turned out ineffective regardless of cabling duct types.

This study attempts to analyze research Quality about home economics and education, based on the studies in the Journal of Korean Home Ecomics Education. The purpose of this study is to investigate the recent studies in hem economics and find out the desirable direction of it. The findings of study are as follow: While the numbers of articles appeared in The Korea Association of Practical Arts Education and Korean Home Economics Education Association are increasing, The Korean Home economics Association does not show the increase the number of articles. According to the historical changes and distribution, the majority was teaching-learning method and teaching materials. Also, from the point of view in research thesis, there were more articles in home economics and education than any others, In addition, among the various types of research, survey was most frequently used. There was significant differences of the sizes of groups according to the different journals, but the one group research was most frequent and one certain research area was dominant. The teams consist of two people showed the highest ratio, and junior high and high school were the most frequently researched institutions. Generally, it is hard to find research grant. Though there is much difference in numbers of references based upon various journals, almost all articles cited reference date not only from Korean articles, but also from international articles.

The measurement-based verification for intensity modulated radiation therapy (IMRT) is a time-and labor-consuming procedure. Instead, this study aims to develop a MU fluence reconstruction method for IMRT QA. Total actual fluences from treatment planning system (TPS, Eclipse 8.6, Varian) were selected as a reference. Delivered leaf positions according to MU were extracted by the dynalog file generated after IMRT delivery. An in-house software was develop to reconstruct MU fluence from the acquired delivered leaf position data using MATLAB. We investigated five patient's plans delivered by both step-and-shoot IMRT and sliding window technologies. The total actual fluence was compared with the MU fluence reconstructed by using commercial software (Verisoft 3.1, PTW) and gamma analysis method (criteria: 3%/3 mm and 2%/1 mm). Gamma pass rates were $97.8{\pm}1.33$% and the reconstructed fluence was shown good agreement with RTP-based actual fluence. The fluence from step and shoot IMRT was shown slightly higher agreement with the actual fluence than that from sliding window IMRT. If moving from IMRT QA measurements toward independent computer calculations, the developed method can be used for IMRT QA. A point dose calculation method from reconstructed fluences is under development for the routine IMRT QA purpose.

The increasing rate of obesity in school aged children has become a conspicuous social phenomenon in Korea. This has been linked to greater economic growth, increasingly westernized dietary habits, and a consumer driven society. Given that obesity can lead to social exclusion or unfavorable attention by other students in a school setting, the design of plus-size garments have become important for effective appearance management skills. This research aimed to establish a somatotype database for obese school boys, aged 10 to 12, in order to develop a sizing system for plus-size upper garments. In order to measure somatotype of average and obese school boys, five categories were recorded; height, obesity, length of trunk, thickness of neck and chest. For obese boys, subcutaneous fat thickness and position of B.P/shoulder point factors were recorded. Obesity factor was subdivided into overall and specific ones, and while the deviation of obese body types was severe compared to the average type. Obese body type showed significantly higher measurements in width, girth, thickness. This is linked to the fact that the frequency ratio of obesity increases with age. Stature and chest were chosen as control dimensions for boys' wear. As crosstabulation of stature(5cm interval) and chest girth(2, 3 and 4cm), and stature(5cm interval)/chest girth(3cm interval) sizing system showed, the most effective cover ratio and adaptability to the data distribution $25{\sim}75$ quartile. Based on the findings, 10 sizes were formulated for average body type, while 18 sizes were formulated for obese type, whose size cover ratios were 48% and 62.9%, respectively. The primary ranges of stature were $145cm{\sim}150cm$, while those of chest girth were $79{\sim}82cm$. Each size was declared as "chest-somatotype{A(average)/O(obesity)-stature". This study proposed a plus-size upper garment sizing systems for obese boys, accompanied with reference measurements for suit, casual wear and underwear. The finding showed that the two systems were totally separate and not overlapping, meaning that plus-size sizing system is essential for obese school boys. The obesity type system had more size and wider range specs.
