This study explored the police organizational health diagnosis index development. and the ultimate purpose of this study is to suggest the ways for the police to develop the police organizational health diagnosis index and then to raise the organizational effectiveness. A police organizational health diagnosis index comprises three categories; Organizational Behavior, Group Behavior, and Individual Behavior. A Organizational Behavior questionnaire comprises five categories; Organizational Structure, Organizational atmosphere, Environmental Compliance, Transformational Leadership, and Communication & decision-making. Secondly, A Group Behavior questionnaire comprises five categories; How to manage the personnel, Conflict management style, Group cohesion, Vision and Strategy, and Community-oriented & shared responsibility. Thirdly, An Individual Behavior questionnaire comprises five categories; Job Motivation, work-related factors, Trust, Vitality, and Organizational Cynicism. This author expects this study to contribute to the development of an adequate measuring instrument of the police organizational health diagnosis index.

Three-dimensional modeling of cities in the real-world is an essential task for city planning and decision-making. And many three-dimensional city models are being developed with the development of wireless Internet and location-based services that identify the location of users and provide the information increases for consumers. Especially, in case of urban areas of Korea, indoor space modeling as well as outdoor is needed due to the high-rise buildings densities. Also location-based services should be provided through spatial analysis such as the shortest path based on a space model. Many studies of three-dimensional city models are feature models. In a feature model, space is represented by combining primitives, and relationships among spaces are represented only if shared primitives are detected. So relationships between complex three-dimensional objects in space is difficult to be defined through the feature models. In this study, Navigable space-relation model(NSRM) is developed, which is topological data model for efficient representation of spatial relationships between objects based on the network structure.

A family resilience approach aims to identify and fortify key interactional processes that enable families to withstand and rebound from disruptive life challenges. Walsh(1998) described family belief systems, organizational patterns, and communication processes as the three main keys of family resilience. The purpose of this study was to identify the three key factors of family resilience in case of divorced female single-parent families in Korea. The study participants were seven divorced mothers who were living in the institutional facility for female single-parent families. Using a qualitative approach, in-depth interviews were audiotaped and transcribed verbatim for analysis. The study findings were as follows. First, the participants showed positive thinking rather than fear about the adversity induced by the divorce. They also showed the senses of competence, control, and self-esteem. However, the senses of transcendence and spirituality were barely evident. Second, emotional and economic supports from parents, brothers and sisters, and community networks (i.e., mother-child protection institution, healthy family support center) enhanced the family resilience of the participants. Third, the participants showed clear communication, open emotional expression, and shared decision making. This study suggests that more counseling services and parent education be provided by healthy family support center and institutional facilities as important family resilience factors for divorced female single-parent families who are below the poverty line.

In late 90s, organizations recognized the information technology as an key enabler of the business strategic accomplishment which lead them heavy increment on IT investment. These organizations tried to hold the competitive advantage by focusing on their core competency. And these acts raise their interests on IT outsourcing. Recent trends of the organizations concern on evaluating the effectiveness of the previous IT investment and the reasonable selection on IT investment type. Also, the objective evaluation of the service level and continuous improvement are major concern of the outsourcer. Consequently, interests on Service Level Agreement (SLA), an immanence operating tool for managing the level of the information system service objectively and qualitatively, were raised among IT outsourcing service providers, outsourcers, and operating departments. Yet, only a few domestic conglomerates adopted the SLA, and exact usage of the SLA is currently unknown. Because of the importance of the SLA between a service provider and an outsourcer, the agreement is treated with high confidentiality. This raised the problems to both the private and public organizations, are considering the SLA, with absence of concrete guide line to internalize SLA management process. This study provides the organizational and environmental factors of the adopting and applying the Service Level Agreement (SLA) by conducting multiple case research. The sampled companies are currently implementing the SLA over 1 year of usage period. Factors were used to provide the operational contribution for implementing the SLA. The study also provides the effects on IT performance through the SLA. For this, in depth interview was conducted for each sampled company. As a result, if SLA between outsourcer and service provider can be used as an immanence operation tool and actively implemented, SLA will be an strategic tool for various decision making in IT management practice with long term relationship, better shared partnership, and continuous service improvement.

For teachers' conceptions and understandings are critical to their decision making and classroom practice, this study attempts to understand pre-service elementary teachers' views and practices of science inquiry during peer teaching practice. Fifteen 4th year university students in teacher education program participated in peer teaching practice. Their teaching and reflective discussion were video and audio recorded and written lesson plans were collected for data analysis. Five science teacher educators individually looked into the data and shared their comments and interpretations on pre-service teachers' views and practice. The study findings suggest that pre-service teachers emphasized the importance of providing students with motivating resources in the beginning of lesson, employing certain inquiry teaching models, the process of predicting and dis/proving via experiment, and teachers' minimal intervention as the important features of inquiry teaching. Science teacher educators emphasized that it is critical to help children understand inquiry questions in the beginning of inquiry process, to be mindful of children's problem solving and critical thinking rather than following instruction models or simply going through prediction and test process. They also commented that teachers' guidance could lead a good inquiry process in classroom practice, not always interfering students' inquiry. Based on the findings, the study suggests science teacher educators need to understand what and how pre-service teachers view and practice science inquiry teaching and consider these as useful resources where they can start effective teaching for pre-service teachers at the university level.

Gastric cancer incidence rates vary dramatically by world region with East Asia having the highest rate. The Asian population of the United States (US) is growing rapidly and over 17 million Americans are of Asian descent. A majority of Chinese, Korean and Vietnamese Americans are immigrants. Americans of East and Southeast Asian descent experience marked gastric cancer disparities and the incidence rate among Korean men in the US is over five times higher than the incidence rate among non-Hispanic white men. Randomized controlled trials have provided evidence for the effectiveness of helicobacter pylori identification and eradication in preventing gastric cancer. Additionally, Japan and South Korea have both experienced improvements in gastric cancer mortality following the implementation of programs to detect early stage gastric cancers. There are currently no clear US guidelines regarding the primary and secondary prevention of gastric cancer in high-risk immigrant populations. However, it is likely that a proportion of US physicians are already recommending gastric cancer screening for Asian patients and some Asian immigrants to the US may be completing screening for gastric cancer in their native countries. Surveys of US primary care physicians and Asian American communities should be conducted to assess current provider practices and patient uptake with respect to gastric cancer prevention and control. In the absence of clinical guidelines, US health care providers who serve high-risk Asian groups could consider a shared decision-making approach to helicobacter pylori identification and eradication, as well as gastric endoscopy.

We performs the cost-benefit analysis, an economical analysis technique, to measure the effect of a shared public supercomputer. The costs of two given alternatives, to share the public supercomputer in a national center and to employ their own supercomputers in the organizations under the necessity, will be estimated and compared for decision making. In the case of sharing, we can simply predict the cost based on the results of the previous public supercomputer. The cost of individual introduction, however, is almost unpredictable since it has a remarkable variability due to the required system performances, locations, human factor, and so on. Accordingly, an objective and valid method to estimate the cost of individual cases will be proposed in this research. Finally, we analyze the economic effect of operating public supercomputer by comparing the sharing cost with that of the individual employs. The results of analysis confirms that the sharing public supercomputer will reduce the operational cost about 10.3 billion won annually compared with the individual introduction. Accordingly, it is expected that the sharing public supercomputer will bring a considerable economical effect.

This study investigates the different characteristics (mainly of community life) in representative intentional communities, between the ecovillage and cohousing, since the different purpose of the establishment of the community might result different characteristics. The study method is data analysis: the analysis material is Community Directory, A Comprehensive Guide to Intentional Communities and Cooperative Living (Rutledge, 2005). Of 750 listed communities, 397 (211 ecovillages and 186 cohousings) communities were analyzed. The findings of the study reveal that there are clear differences of community life between ecovillages and cohousings even though two communities are regarded as similar intentional communities. The similarities between the two communities are as follows: 1) Those mostly distributed in the USA, and established before 2000. 2) Dominant size of intentional communities is less than 20 residents and 20 houses. 3) They make decisions in consensus. 4) They eat together very frequently; at least once a week or more. 5) Shared work is required. The differences between the two communities are as follows: 1) They have different aims of establishment. For instance, ecovillage focus more on eco-living, while cohousing focuses more on the cohousing idea. 2) There are more female residents in cohousings than in ecovillages. 3) There are more cohousings in urban areas with a smaller area of land, contrary to that there are more ecovillages in rural areas with larger areas of land. 4) There are less identified leaders or leadership core groups in cohousing than in ecovillages. 5) Income sharing is more common in ecovillages than in cohousings. According to there findings, it is evident that a different purpose of establishment result in different characteristics of community life even though those belong to the similar category of the intentional community. Thus, it is recommended to adapt the correct characteristics that fit the aim of the community in the establishment an intentional community Topics and discussions about establishing intentional Topics and discussions abut establishing intentional communities could contribute to gather the intentional communities could contribute to gather the interests communities could contribute to gather the interests of residents as well as those of relevant civil-workers and administrators in Korea.

Purpose : This study was designed 1) to compare the perception of dental professionals and lay people with respect to minor variations in maxillary anterior tooth size and alignment and their relation to the surrounding soft tissues, and 2) to evaluate the normal tooth-gingiva topographical relationships in periodontally healthy young subjects, Materials and methods : Maxillary anterior teeth were intentionally diagrammed in varying degree of deviation with respect to one of three common anterior esthetic discrepancies including variations in crown length, shape of gingival margin, and length of interproximal contact, 17 images were generated to be preferentially selected by 2 groups consisting of dental professionals and lay people (total of 740). Smiling photographs of 120 dental students who had healthy periodontium were taken and the photographic images were analyzed to be classified as 17 kinds of altered image groups. Results : The results demonstrated noticeable difference between the varying levels of discrepancy. Both group preferred gingival margin of lateral incisor to be 0.5mm lower than that of central incisor. Lay people preferred the gingival margin shape that has 2/9 horizontal component of the crown width, while dental professionals preferred the gingival margin shape that has 1/9 horizontal component of the crown width. Lay people preferred longer length of the interproximal contact (two thirds of the crown length), whereas dental professionals preferred shorter length of the interproximal contact (half of the crown length). Photographic analysis of normal esthetic gingival topography revealed 2/9 horizontal component and short length of the interproximal contact which was of the hybrid nature of the preferences shared by lay people and dental professionals. Conclusion: The results of this study show that dental professionals and lay people demonstrated significant difference in their preference of dental esthetic components, which may then influence the decision making process by dental professionals with respect to designing the anterior esthetic gingival line.

The future battlefield environment has changed platform centric warfare into a network centric warfare. The NCO is a operational concept to improve combat power through information sharing, shared situational awareness, decision making and synchronized action based on powerful network grid. In addition, these operational environment is composed of physical, information, cognitive and social domains. The platform environment system is associated with the OSI 7 layer. However, OSI 7 layer is limited to express NCW environment including cognitive and social domains. Therefore, we requires a new model for expressing cognitive and social domains. After we developed a new model, this model applied to the NCW architecture taxonomy.
