The relationship between an adolescent and his/her parents is one of the most important relationships that can have a significant effect on adolescents' well-being and functioning. While there has been an increase in research on Asian American families in recent years, still much less is known about adolescent-parent relationships in these families. Asian American adolescents face some of the challenges that mainstream European American adolescents face, but their experiences are complicated by the cultural and immigration-related factors that have unique contribution to their relationships with their parents. As such, there is urgent need for research that identifies and provides a comprehensive understanding of factors that contribute to the experiences of Asian American immigrant families. The current paper provides a systematic look at adolescent-parent relationships in Asian American immigrant families using the Bronfenbrenner's ecological model. More specifically, this paper provides a succinct review of the literature on developmental issues, immigration, and culture-related factors that affect Asian American adolescent-parent relationships, and guided by Bronfenbrenner's ecological theory, an ecological framework of Asian American adolescent-parent relationships is proposed.

Although people's anxiety about the environmental problem has been getting higher, they are not provided good quality of knowledge about the environment. Based on this situation, Ecoblog can be a new type of online community to educate the public in ecological knowledge. Especially, Ecoblog can be utilized as a method of "preventive education", and it will contribute to reduce great amounts of environmental budget to restore contaminated environment to previous condition. Ecoblog also utilizes the concept of blog which user can create and append their site with chosen themes. A weblog or a blog is a non-commercial webpage regularly updated through the use of a blogging software which allows the user to "publish" kinds of amalgamations of text and graphics to the page as posts. The technology offered in Ecoblog is utilizing the concept of 4D place and game metaphor in order to provide users the sense of participation, interaction and immersion among them and the growing community. Thus, it requires applying the CAAD technology by implementing semantically well-defined building data model as a core database to create a 4D virtual community. This research focuses on defining a 4d spatial framework suitable for developing an online ecological community. Through our study, the state-of-the-art of online community has been studied at the first step. Second, the scenario of using EcoBlog described with content, visualization and navigation are defined based on the critical features derived at the first step. Finally, a 4d spatial framework composed of semantic building data model, content and rule database is constructed to propose factors that are necessary to establish an ecological virtual community. In conclusion, our framework could enhance the comprehension and interaction between users and virtual buildings in the ecological community by integrating the concept of game design, 4D CAD and semantic data model. Such framework can be applied to any online community for an educational purpose.

Objectives : We measured behavioral factors associated with Koreans receiving gastric cancer screening based on a socio-ecological model, in part to develop strategies to improve cancer screening rates. Methods : A telephone survey was conducted with 2,576 people chosen through stratified random sampling from April 1 - May 31, 2004. Collected information included gastric cancer screening, socio-demographic factors, and socio-ecological factors at intrapersonal, interpersonal, community, and public policy levels. Results : Among 985 survey respondents(380 men and 605 women), 402 had received gastric cancer screening. Logistic analysis was performed to compare those screened and unscreened. 'Age' was the only demographic factor that showed a statistically significant association with getting screening. People in their fifties (OR=1.731, 95% CI=1.190-2.520) and sixties (OR=2.098, 95% CI=1.301-3.385) showed a higher likelihood of getting screened, compared to those in the forties. 'Accessibility to a medical institution' was a significant factor related to having gastric cancer screening at the intrapersonal level. At the interpersonal level, recommendations by family members to be screened and a family practice of routine cancer screening were significantly related. People with frequent education about cancer screening or with stronger social feelings that cancer screening is necessary also demonstrated significantly higher tendencies to be screened. Conclusions : In conclusion, a socio-ecological model seems appropriate for explaining gastric cancer screening behavior and associated factors. Health planners should develop integrated strategies to improve cancer screening rates based on socio-ecological factors, especially at the interpersonal and community levels.

이 논문은 학교폭력을 예방하고 대처하기 위해서는 학교폭력의 원인에 대한 정확한 진단이 선행되어야 한다고 보고, 학교폭력을 유발하는 요인이 무엇인지 생태학적 관점에서 고찰하는데에 그 목적을 두었다. 이를 위해 Bronfenbrenner(1979)의 생태학적 발달이론의 영향을 많이 받은 Benbenishty와 Astor(2005)의 학교폭력 관련 요인들에 대한 생태학적 경로모형을 간단히 살펴보았고, 이 모형에 기초하여 학교폭력의 유발 요인으로 학교 요인, 개인 요인, 가정 요인, 지역사회 요인으로 구분하여 관련 문헌과 선행연구를 고찰하였다. 이러한 고찰을 통해 본 논문에서는 학교폭력은 한 가지 원인이 아닌 학교, 개인, 가정, 지역사회 관련 요인 등 여러 원인이 복합적으로 작용하여 발생하는 이른바 '폭력의 종합 세트'이기 때문에 이러한 요인들을 고려한 종합적 처방을 마련하여 장기적인 노력을 기울여야 한다는 점과 본 논문에서 고찰한 학교폭력의 유발 요인과 그 영향에 대한 성찰을 토대로 학교와 가정 및 사회를 바로 세워나갈 때 학교폭력의 대책이 진정성과 효과를 지니게 될 수 있다는 점을 강조하였다.

Climate change is considered a severe global problem closely related to carbon storage. However, recent urbanization and land-use changes reduce carbon stocks in terrestrial ecosystems. Recently, the role of protected areas has been emphasized as a countermeasure to the climate change, and protected areas allow the area to continue to serve as a carbon sink due to legal restrictions. This study attempted to expand the scope of these protected areas to an evaluation-based environmental spatial information theme map. In this study, the area of each grade was compared, and the distribution of land cover for each grade was analyzed using the Ecological and Nature Map, Environmental Conservation Value Assessment Map and Urban Ecological Map of Sejong Special Self-Governing City. Based on this, the average carbon storage for each grade was derived using the InVEST Carbon model. As a result of the analysis, the high-grade area of the environmental spatial information generally showed a wide area of the natural area represented by the forest area, and accordingly, the carbon storage amount was evaluated to be high. However, there are differences in the purpose of production, evaluation items, and evaluation methods between each environmental spatial information, there are differences in area, land cover, and carbon storage. Through this study, environmental spatial information based on the evaluation map can be used for land use management in the carbon aspect, and it is expected that a management plan for each grade suitable for the characteristics of each environmental spatial information is required.

Prediction of the behavior of heavy metals over time is important to evaluate the heavy metal toxicity in algae species. Various modeling studies have been well established, but there is a need for an improved model for predicting the chronic effects of metals on algae species to combine the metal kinetics and biological response of algal cells. In this study, a kinetic dynamics model was developed to predict the copper behavior(5 ㎍ L^-1, 10 ㎍ L^-1, and 15 ㎍ L^-1) for two freshwater algae (Pseudokirchneriella subcapitata and Chlorella vulgaris) in the chronic exposure experiments (8 d and 21 d). In the experimental observations, the rapid change in copper mass between the solutions, extracellular and intracellular sites occurred within initial exposure periods, and then it was slower although the algal density changed with time. Our model showed a good agreement with the measured copper mass in each part for all tested conditions with an elapsed time (R² for P. subcapitata: 0.928, R² for C. vulgaris: 0.943). This study provides a novel kinetic dynamics model that is compromised between practical simplicity and realistic complexity, and it can be used to investigate the chronic effects of heavy metals on the algal population.

The purpose of this study was to propose an efficient management plan for purchased land considering the hydrological, watershed characteristics and ecological functions of the target land and surrounding area based on the result of monitoring the water quality improvement effect obtained by purchasing the land in the watershed area in the Geum river system. For this purpose, this study investigated through literature review, and examined ways to apply them to this research by deriving implications from a comprehensive analysis of previous research cases. After that, the components of assessment were derived to evaluate the ecological function of the purchase land, and the ecological function evaluation model for each land and area was proposed. In order to select purchase and restoration priorities of the land, this study analyzed the ecological status of the purchased land in main watersheds and tributaries using Arc GIS ver 10.1. Through this, a process to select restoration priorities was developed. And this study constructed the integrated management process with proposing a mid - to long - term plan by integrating the purchased land valuation and restoration priority selection process. Based on this process, this study suggested an effective management plan for purchased land through the integrated ecological management system of lands purchased. It can be used systematically in appraisal valuation, land purchase system, restoration project, and follow-up management of land purchase.

This study aims to analyze the effect of urban ecosystem restoration projects by evaluating the short-term restoration performance of the project sites, from both qualitative and quantitative evaluations. In this study, for the qualitative evaluation, we derived the evaluation frame from previous studies and literature. For the quantitative evaluation, the changes in ecological connectivity after the restoration project were described using landscape permeability and network analysis. In addition, changes in habitat quality after the restoration project were evaluated by using InVEST Habitat Quality Model. These evaluations were applied to the three natural madang (ecological restoration) projects and two ecosystem conservation cooperation projects. As a result, three categories, 10 indicators, and 13 sub-indicators were derived from literature as the evaluation frame for this study. In the case of quantitative evaluation of restoration performance, habitat quality increased by 45% and ecological connectivity by 37% in natural-madang, and habitat quality by about 12% and ecological connectivity by about 19% in ecosystem conservation cooperation projects. This implies that the ecological restoration project can increase the ecological connectivity and the habitat quality of degraded sites even in a short period of time by improving the land-cover and land use. The results by applying the evaluation frame indicated that ecological and environmental factors and the ecological functions were improved by the restoration works, even though the magnitude of performances were diverse depending on the specific evaluation items, project type, and site characteristics. This study clarified that the success of ecological restoration project should be assessed by both of the short-term and long-term goals, which can be achieved by the maintenance and sustainable management, respectively.

Reckless development policy, which has continued during the past several decades, caused landscape damage. In order to solve this problem, it is very urgent to conserve the habitat and to establish systematic database. Recently, various researches related to landscape damage have been conducted actively and the necessity of landscape ecological planning based on the biotop mapping has been issued as one of the solutions. Therefore, the purpose of this study is to select the study area, which is located in Guji-meon, Dalseong-gun, Daegu and will be formed into Daegu Science Park, and then to develop and apply the landscape ecological planning model based on biotop mapping in district unit. The results are as follows. Fist of all, according to the results of biotop classification with field survey and literature review, total 13 biotop and total 63 biotop types were classified. According to the first evaluation with B-VAT, total 19 biotop types were classified I grade including natural river with abundant plants(BA) and so on. While V grade, which has lowest value, was classified 16 biotop types including vegetable garden adjacent to river(BC). Also the second evaluation, we analyzed total 30 areas such as 1a, 1b grades, which had special meaning for the conservation of species and biotop. Next, 2a, 2b, 2c grades were analyzed total 82 areas. Secondly, in the compliance with Ecological landscape planning, we divided landscape planning model into two parts such as setting of improvement goal and detailed implement plan. For instance, setting of improvement goal, we classified 9 parts such as conservation region and parts of detailed implement plan, we classified total 28 planning indicators with 4 view such as the region which should be special protected from nature and landscape. Lastly, with the developed landscape model we applied to research areas, made maps, and differentiate proposals in each region. Specially, the final master plan was made to help understand the contents of detailed landscape planning. This study will be a useful data, which can solve the landscape damage problem systematically and control it landscape-friendly with biotop classification, evaluation, landscape ecological planning model, and application method which we developed.
