The purpose of this study is to research support systems of the community child care services for optimum work-family balance. For this purpose, the questionnaire to be completed combined four areas: the workplace, school, community and home. Then questions concerning demographic factors and community-related aspects were analysed for this article. After analyzing 197 questionnaires, supplementary questions were asked, by interview to 10 samples. Full-time working wives (eg. working from 9am to 6pm) who have 1 or more children under 10 years old, living in Seoul and Gyeonggi province were collected as samples. The results were as follows: First, child care from family and relatives, and community services was properly used during the week, but dual working parents took complete charge of child care on Saturdays. Second, emergency child care was usually provided by the family, while relatives and community child care services were used less. Third, parents spent 17% of their monthly income on total child care expenditure. Fourth, community child care services were not used often, but the level of satisfaction with them was very high. Finally, they used relatives' services for safety reasons and community services for location, and only based on informed decisions. Therefore, Saturday child care programmes need to be initiated to help physically and mentally tired parents, with more general provision of positive and diverse public support systems.

Purpose: A study analysed the stress distribution of abutment screw and supporting bone of fixture by the tightening torque force of the abutment screw within clinical treatment situation for the stability of the dental implant prosthesis. Methods: The finite element analysis was targeted to the mandibular molar crown model, and the implant was internal type 4.0 mm diameter, 10.0 mm length fixture and abutment screw and supporting bone. The occlusal surface was modeled in 4 cusps and loaded 100 N to the buccal cusps. The connection between the abutment and the fixture was achieved by combining three abutment tightening torque forces of 20, 25, and 30 Ncm. Results: The results showed that the maximum stress value of the supporting bone was found in the buccal cortical bone region of the fixture in all models. The von Mises stress value of each model showed 184.5 MPa at the 20 Ncm model, 195.3 MPa in the 25 Ncm model, and 216.5 MPa in the 30 Ncm model. The contact stress between the abutment and the abutment screw showed the stress value in the 20 Ncm model was 201.2 MPa, and the 245.5 MPa in the 25 Ncm model and 314.0 MPa in the 30 Ncm model. Conclusion: The increase of tightening force within the clinical range of the abutment screw of the implant dental prosthesis was found to have no problem with the stability of the supporting bone and the abutment screw.

"Watoji" is a Japanese traditional book binding technique. An aim of this research develops a support system which everyone can make Watoji easily by. This system uses a working situation by recognizing a position of a needle and annotating to a book directly by mixed reality technique. Additionally, a technique of recognizing a working situation at a book is sewn by a needle is proposed. The proposed system of recognizing a position of a needle is build, then we experiment recognizing of a needle from an image. Furthermore, setting up Watoji on the system, we experiment recognizing of a position of a needle. An experimental result shows recognizing a needle from an acquired image from a camera. Using this result, a working situation can be recognized. Then, suitable information to a working situation can be presented.

In spite of the previous research that had been emphasizing the importance of parents' assistance for revealing genius and achievement of their children, there was not enough information about how to drive the parents participation and support. Not considering "what and why" about the supporting of parents of gifted students, it was vaguely generalized that the education from the supporting parents was important. However, this situation will have a possibility of missing out on more important things of gifted children's parental support. Therefore, this research will deal with a variety of effective ways to clarify what the parents can do to support their gifted children and the problems that are related to those ways. Furthermore, by suggesting some of the ways that can complement the system of current parental support, it will set up fundamental ways to help the supporting parents.

The construction of shield tunnelling in urban sites is facing serious risks from complex and changeable underground conditions. Construction problems in the sand-clay mixed ground have been more reported in recent decades for its poor control of soil loss in tunnel face, ground settlement and supporting pressure. Since the limitations of observation methods, the conventional physical modelling experiments normally simplify the tunnelling to a plane strain situation whose results are not reliable in mixed ground cases which exhibit more complicated responses. We propose a new method for the study of the mixed ground tunnel through which mixed lays are simulated with transparent soil surrogates exhibiting different mechanical properties. An experimental framework for the transparent soil modelling of the mixed ground tunnel was established incorporated with the self-developed digital image correlation system (PhotoInfor). To understand better the response of face stability, ground deformation, settlement and supporting phenomenon to tunnelling excavation in the sand-clay mixed ground, a series of case studies were carried out comparing the results from cases subjected to different buried depths and mixed phenomenon. The results indicate that the deformation mode, settlement and supporting phenomenon vary with the mixed phenomenon and buried depth. Moreover, a stratigraphic effect exists that the ground movement around mixed face reveals a notable difference.

A context-aware services platform supporting mobile agents consists of sensor nodes and a sensor coordinator. Sensor nodes collect environmental information and transmit the collected information to the sensor coordinator through wireless sensor networks. The sensor coordinator passes the information to the context-aware service module, and the mobile agent. The context-aware service module or the mobile agent performs services suitable for a user's situation based on the environmental information and a service actuation message is delivered to an actuation node through the sensor coordinator. In this paper, we present a context-aware services platform structure employed in our project, and describe context-aware services platform interfaces with a context-aware service module and mobile agents.
