Recently there has been increasing the population of the elderly, the welfare of the elderly is no longer family's and personal problems. It is a social issue that the communities have a role to supply the systematic welfare service of the elderly and the facilities. Therefore It is needed to study the extended function and role of Gyungrodang because Gyungrodang is the most wide spreaded welfare service facilities for the normal elderly in urban single housing district. The subject of this study is to propose the facilities' program improvement method for the Gyungrodang that hold a extended role as a community welfare service facility for the elderly. This paper Is assessed as an sustainable research of normalization of the old people's living. By the comparison analysis of the existing Gyungrodang in Daejeon City and the investigation results of the welfare service present condition of the elderly in Daejeon City, finally the facilities' program improvement direction for the Gyungrodang is proposed.

The existing access control models have the demerits that do not provide the limit function of using resources by time constraint, the restricted inheritance function as a superior role in role hierarchy, the delicate delegation policy and the limit function of using resources by the location information about a user for the access control in ubiquitous environment. This paper proposes an Extended-GTRBAC model is suited to the access control in ubiquitous environment by applying to sub-role concept of GTRBAC model that the application of resources can be restricted by the period and time and PBDM and considering the location information about a user on temporal constraint. The proposal model can restrict the inheritance of permission in role hierarchy by using sub-role, provide the delicate delegation policy such as user-to-user delegation, role to role delegation, multi-level delegation. multi-step delegation, and apply diverse and delicate access control policy which is suited the characteristic of ubiquitous environment by considering the location information about a user on temporal constraint.

The nature of work which is changing has increased the importance of HRD within organization. Also, these changes are making HRD shift its paradigm : from the segregated, closed, operational & administrative, dependent, utilitarian view to the integrative, open, strategic & facilitative, interdependent, generative view. The shifts of the perspective on HRD cause HRD professionals rethink the purpose and definition of HRD, and the role & competency needed to HRD in 21st century. The findings which are drawn through literature review and researcher’s intuition based on a long field experience are as follows. First, The function of HRD has recently been much more important then that of the past. Second, There is no consensus over the conceptual identity of HRD. Nonetheless, it is apparent that the preferred activities of the HRD function is performance improvement. Third, It is too difficult that we should define clearly the role & competency of HRD because of diverse perspectives on them. But we find much evidence converging to support the fact that the role & competency of HRD should be extended from the sole focus on training & development to adding the additional role & competency of change agent, who includes planning, implementing, and managing change.

The purpose of this paper is to identify factors affecting the optimum mix of required inputs and other relevant factors which account for the variation in physician's productivity in general hospitals, and to find out their implications for the efficient health planning and management. An extended version of Cobb-Douglas production function and cross sectional data of one day patient census from all general hospitals in Korea in 1988 were used in the analysis. Main results of the analysis and their implications could be summarized as follows : (1) The production function for physician's inpatient service shows the evidence of economies of scale, but the production function for physician's outpatient and adjusted-patient service, which combines both out- and in-patient service, shows that of dis-economies of scale. (2) The physician's role for production for all service is smaller than auxiliary personnel's, which imply that more intensive utilization of nurses, nursing aides and other auxiliary personnel is desirable for improving general hospital productivity (3) In case of physician's inpatient and adjusted-patient service, nurses' role is greater than nursing aides'. Therefore, more extensive utilization of nurses is recommended for the efficient operation of general hospitals. (4) The factor of hospital beds plays the leading role among required inputs in the production for physician's in- and adjusted-patient service. (5) The physician's productivity of general hospitals in rural area is lower than that in urban area. And the productivity of teaching hospitals is lower than that of the other hospitals. Further analysis was made in physician production function based upon the size of hospitals, namely those hospitals below 250 beds and those above. Explained variances by the factor of hospital beds was significantly increased in the case of those hospitals above 250. A more detailed and thorough investigation is needed for verifying factors influencing physician's productivity in general hospitals in Korea.

The purpose of this study is to inquire the building process of Pedagogical Content Knowledge of prospective mathematics teachers about the function concepts. For this purpose, We performed the following steps; First, we performed the survey relaying to the prospective mathematics teachers' teaching experiences, capabilities of their error evaluation of the students, and viewpoints about the function concepts. Second, we performed the survey on the subject-matter knowledge about the function concepts and the key items of designing teaching plans about the function concepts. And then, we interviewed the participants to check the results of the surveys and to supplement the necessary contents. The collected data was relatively correlative and analyzed in the process. As a result, we found the followings; First, subject-matter knowledge of prospective mathematics teachers about the function concepts is different depending on the grades. Second, prospective mathematics teachers are building more extended function concepts through the major subjects. Third, the major subjects are important to build the Pedagogical Content Knowledge of function concepts. Fourth, teaching experience plays an important role in transforming subject-matter knowledge of function concepts to Pedagogical Content Knowledge of it. Fifth, building the Pedagogical Content Knowledge means transferring the teacher's viewpoint from himself/herself to the learner.

Early mosque architecture is time that islam attempts fixing since hjira by Muhammad. Before Umayyad dynasty is established a country since islam occurrence, islamic influence was not extended much and stayed in Mecca area. Of course, when is Patriarchal Caliphate period, although there was part territorial expansion, was in existing islam influence still. Regular territorial expansion to Umayyad dynasty several influences and religious conflict happen. Change about islamic architecture occurred much fatally. Therefore, can find islamic archetype about islamic architecture until Prophet Muhammad period and Patriarchal Caliphate period. Also, Muhammad that is Islamic originator participated to mosque architecture directly in life. Can understand philosophy about islamic architecture that Muhammad seeks in mosque architecture. Was age that seek Muhammad's philosophy department religious succession strongly to Patriarchal Caliphate period. Therefore, can understand role of religion, mosque architecture's meaning and role that seek in Islam. It was just before that early mosque architecture receives effect of conquest area or the surrounding country. Therefore, characteristic of mosque received much effect of Prophet Muhammad and qur'an. Do construction according to qur'an's notice based on Prophet's house's function to early mosque. qur'an is no direct delineation as form or architecture element. qur'an refers thing about spiritual aspect or function about special quality of mosque, role etc..

Along with the rapid development of the economy, the urban scale has extended rapidly, leading to the formation of different types of urban function districts (UFDs), such as central business, residential and industrial districts. Recognizing the spatial distributions of these districts is of great significance to manage the evolving role of urban planning and further help in developing reliable urban planning programs. In this paper, we propose an automatic UFD division method based on big data analysis of point of interest (POI) data. Considering that the distribution of POI data is unbalanced in a geographic space, a dichotomy-based data retrieval method was used to improve the efficiency of the data crawling process. Further, a POI spatial feature analysis method based on the mean shift algorithm is proposed, where data points with similar attributive characteristics are clustered to form the function districts. The proposed method was thoroughly tested in an actual urban case scenario and the results show its superior performance. Further, the suitability of fit to practical situations reaches 88.4%, demonstrating a reasonable UFD division result.

Studies of earthquakes over the last 50 years and the examination of dynamic soil behavior reveal that soil behavior is highly nonlinear and hysteretic even at small strains. Nonlinear behavior of soils during a seismic event has a predominant role in current site response analysis approaches. Common approaches to ground response analysis include linear, equivalent linear and nonlinear methods. These methods of ground response analysis may also be categorized into time domain and frequency domain concepts. Simplicity in developing analytical relations and accuracy in considering soils' dynamic properties dependency to loading frequency are benefits of frequency domain analysis. On the other hand, nonlinear methods are complicated and time consuming mainly because of their step by step integrations in time intervals. In part Ι of this paper, governing equations for seismic response analysis of surcharged and layered soils were developed using fundamental of wave propagation theory based on transfer function and boundary conditions. In this part, nonlinear seismic ground response is analyzed using extended HFTD method. The extended HFTD method benefits Newton-Raphson procedure which applies regular iterations and follows soils' fundamental stress-strain curve until convergence is achieved. The nonlinear HFTD approach developed here are applied to some examples presented in this part of the paper. Case studies are carried in which effects of some influencing parameters on the response are investigated. Results show that the current approach is sufficiently accurate, efficient, and fast converging. Discussions on the results obtained are presented throughout this part of the paper.

This study aims at establishing an digital signal processing technique to control 3-D sound localization, especially focusing our eyes on the role of information provided by Head-Related Transfer Function(HRTF). In order to clarify the cues to control the auditory distance perception, two conventional models named Hirsch-Tahara model and auditory parallax model were examined. As a result, it was shown that both models have limitations to universally explain the auditory distance perception. Hence, the auditory parallax model was extended so as to apply in broader cases of auditory distance perception. The results of the experiment by simulating HRTFs based on the extented parallax model showed that the cues provided by the new model were almost sufficient to control the perception of auditory distance from an actual sound source located within about 2 m.
