Since the late 1990s Korean housing authorities and private companies have been pursuing various initiatives towards sustainable neighbourhood design, however, there has been no attempt to examine their progress. This research aims to suggest a sustainability evaluation framework and analyse the progress of sustainability of a cutting edge project: Shinjung Environmentally Friendly Housing Estate Development, using that framework. The results of the analysis suggest that the project failed to make Significant progress in the sustainability evaluation criteria compared to normal projects in Korea and there exist significant barriers: economic/financial barriers; institutional/structural barriers; and implementation barriers within current planning and design practices. Most of the project's design strategies were simply adopted and used as a marketing tool without public participation, sustainability targets or benchmarking for sustainability. Furthermore, most of the responsibility for maintenance was left to residents who normally lack the knowledge, experience, interest and money to carry out such tasks. These problems cause significant concerns over the future success of the project toward sustainability. The experience of the Shinjung project also highlights the need for a more proactive central and local government stance towards sustainable neighborhood design.

In this paper, we present one approach to achieve safe navigation in indoor dynamic environment. So far, there have been various useful collision avoidance algorithms and path planning schemes. However, those algorithms have a fundamental limitation that the robot can avoid only "visible" obstacles. In real environment, it is not possible to detect all the dynamic obstacles around the robot. There exist a lot of "occluded" regions due to the limitation of field of view. In order to avoid possible collisions, it is desirable to consider visibility information. Then, a robot can reduce the speed or modify a path. This paper proposes a safe navigation scheme to reduce the risk of collision due to unexpected dynamic obstacles. The robot's motion is controlled according to a hybrid control scheme. The possibility of collision is dually reflected to a path planning and a speed control. The proposed scheme clearly indicates the structural procedure on how to model and to exploit the risk of navigation. The proposed scheme is experimentally tested in a real office building. The presented result shows that the robot moves along the safe path to obtain sufficient field of view, while appropriate speed control is carried out.

This study aimed to examine the needs for the planning of group homes for the elderly with dementia in lower income class, who have more economic burden on the caring the demented aged. The survey was conducted by questionnaires collected from 300 respondents from December 2000 to March 2001. Methods of analysis were frequency distribution, mean and chi-square test. The results of this study were as follows: 1) The respondents perceived that the responsibility to take care of the elderly with dementia belonged to their family, not to society or the government, and the sons and daughters had to share the burden placed on care-givers. 2) The awareness of group homes for dementia was relatively low. 3) The respondents' needs for the group homes with dementia could be summarized as follows; small scale plan with homelike atmosphere, a total of 6-8 residents, structural type of detached house or three-storied town house, 2-3 persons per individual room, and management system by non-profit organization or the government. There were no big differences between the respondents of this study and upper and middle class studies conducted by other research, except for some details. Referring to results of this study, it is asserted that group homes for the elderly with dementia would be embraced throughout the country if poetical assistance combined with economic support were provided.

Background: The purpose of this study is to evaluate the outcomes of four patients receiving stock Biomet TMJ prosthesis for reconstruction of the TMJs. Methods: TMJ reconstruction with stock Biomet TMJ prosthesis was performed in four patients who had joint damages by trauma, tumor, resorption, and ankylosis, which represent the indications of alloplastic prosthesis. Results: Loss of condyle from trauma and resorption of joint are good indications for prosthesis, but the patients should be informed about limitation of jaw movement. In case of structural damage of TMJ by tumor, tumor recurrence should be considered before planning TMJ reconstruction. Considering heterotopic bone formation in case of ankylosis, periodic follow-up and special surgical technique are required. Conclusions: Given careful treatment planning and understanding the functional limitation of TMJ prosthesis, alloplastic prosthesis is a safe and effective management option for the reconstruction of TMJs.

The purpose of the study, approaching from the aspect of the construction technologies, is to determine the architectural techniques of traditional wood architects in existence, through which the systems and techniques that create the inherent characteristics of Korean Architecture are clarified. With understanding traditional construction system and focusing on the fact that built environment results from the consistent standards and technologies of architects, this study inquires into the systematic standard and its formation that present in the process of planning for the overall scale and shape of a building from the following (four) perspectives. The study determines the characteristics of '間(Kan)' (unit; fundamental unit that measures Korean traditional houses) and the methods of columns disposition of which the '間 (Kan)' is made up. Once the necessary spaces are decided according to the size of a building, then floor plans are drawn with the standard unit, '間(Kan)'. The '間(Kan)', as a modular unit, is not only composing the floor plans, but also functioning as an Area unit, Space unit and Structural unit. Composition of '間(Kan)' varies with disposition of columns, and therefore multiform of floor and spaces are created. In this study, the '間(Kan)', as a standard unit, is used in the form of specific size and area, and it is demonstrated how the floor plans are developed by organizing the columns in accordance with the spaces requested.

Statement of problem: It is important to have a correct presurgical treatment plan before any implant surgery. It must contain substantial information about the patient concerned. However, the standard classification only notifies the dentist about various structural, pathological and physiological dimensions Due to diverse structure of the jaw bone, current standard classification does not tell spatial dimensions of the available bone for implant insertion sites. Purpose of study: The purpose of this study is to report the establishment of the systematic implant treatment plan and its clinical treatment using $Implan^(R)$ program which is based on ASCIi-classification that is available for future diagnosis and scale of treatment and for systematic implant insertion. Results: By assisting the systemic measurement of the available alveolus dimension during implant surgery, it was easy to set initial implant treatment plan. Conclusion: Using $Implan^(R)$ program which is based on ASCIi-classification system that allows the establishment of systemic implant treatment plan and successful clinical performance, it was possible to establish the founding or initial implant treatment plan , the acquisition of information, and the systematization of documentation.

This study examines the socioeconomic determinants of fertility behavior in Korea by developing a model which simultaneously takes into account both individual and community-level differences. It especially focuses on the micro-macro nexus of fertility behavior depending on social contexts. This study utilizes micro data obtained from the 1974 Korean National Fertility Survey(KNFS), and macro data obtained from Korean government statistics. The framework of the model is formalized as a set of structural equations modelling the fertility process. The model is formed on a cohort-specific processual basis and is restricted to five-year birth cohorts. Three cohorts of women are studied : those aged 30-34, 35-39, and 40-44. The model includes three fertility-process components : age at first birth, early fertility, and later fertility, which are defined by reference to the age of the mother. The results of this study indicate that socioeconomic development in Korea results in increased age at first birth and reduced numbers of children per couple. In addition to the developmental change, Korea's fertility decline is found to be facilitated by family planning programs. As expected, the effect of family planning on fertility is greater among better-educated women than among poorly educated women. The inconsistent but suggestive result, however, is that the effect of socioeconomic development on fertility is greater among less-privileged women than among more-previleged women.

The purpose of this study was to analyze the status of conservation and management of KIAHS(Korea's Important Agricultural Heritage System) by focusing on which of the conceptual and institutional characteristics and stakeholder activities, and to suggest improvement plans. The results were summarized as follows, first, insiders prioritize financial support and participate in plan execution and activities. Second, rural utilization and traditional agricultural succession activities and support are deficient. Third, administrators (intermediary) focuses primarily on KIAHS designation; ordinance enactment, manpower recruitment and other structural considerations are lacking. Fourth, the role of administrators (intermediary) is limited to operational funding and facility management support at the enforcement and activity stage. Fifth, outsiders besides visitors, such as the public or business enterprises, lacked participation methods. For the sustainable KIAHS, municipality must perceive agricultural heritage as a resource and recognize the importance, and treat it accordingly. The establishment of local-led conservation activities and movements must be considered in an enhanced investigation and excavation stage. The complementary policies that ensure continual support from experts from the first investigation and excavation stage to the final monitoring stage are necessary. The standards and regulations are necessary to achieve parity between conservation and maintenance of agricultural heritage, and its utilization.

This study analyzed the factors influencing the choice of new farming type in order to prepare the countermeasures against structural changes of farm labor force. The analytical model was the multinomial logit model(MNL). The test for Independence and Irrelevance Alternatives(IIA) assumption in MNL shows that the IIA assumption in our data is rejected. Alternatively, we chose the multinomial probit model(MNP) that does not assume IIA. Data were obtained from 2010 census of Agriculture, Forestry and Fisheries of Statistics Korea. New farming types are succession(13.9%), return-to-farming(45.0%), part-time-farming(32.5%) and etc(8.6%). Analysis results showed that the characteristics of farms, commodity, management, and region influenced the choice of new farming type. This study is expected to help policy makers to produce support policies by new farming types in order to increase the number of new farmers and to make them easier to settle down in agriculture.

A status of air traffic controller is a government officer and air traffic controllers who work at airport are divided by duty rating and work experience. Abiding by law, rules and regulation, air traffic controllers are working together based on mutual trust. This paper's theoretical background is based on cultural bias theory. The theory divide people group into four groups according to cultural bias such as fatalism, hierarchy, individualism and egalitarianism. A research model was designed how such four cultural bias could affect air traffic controller's risk response in case of emergency or abnormal situation during their work. Depend on empirical research, it was found that air traffic controllers perceived they had been more biased to fatalism than hierarchy. The characteristics of fatalism group are as follows: first of all, they follow rigid rules and regulation. However, they have less self-efficacy compared to other government officers. According to structural equation model, air traffic controller's fatalism had a significant negative effect on organizational royalty. Their royalty, however, had a very significant positive effect on planning response and immediate response.
