Objective : The experiment consists of measuring functional grasp ability of a child suffering from sensory defense disability of the hands as the child is treated with sensory integration therapy. Methods : We treated two-year-old child with developmental disability to set up the reversal design(ABAB design). We used treatment equipments, free activities, and toys for sensory integration therapy. Results : A child's functional grasp ability did not show anything before the sensory integration therapy, however, after the sensory integration was applied during the first treatment(Treatment 1), the five minutes before the treatment, it averaged 1.87 times(ranges=0 to 5 times), the five minutes after the treatment, it averaged 1.25 times(ranges=0 to 8 times) showing an increased. After ending the sensory integration therapy, the functional grasp ability averaged 2.5 times before the therapy and 4 times after the therapy, which showed a totally different tendency, when we reapplied the treatment during the second treatment(Treatment 2), it averaged 2.4 times(ranges=1 to 4 times) before the treatment, and it averaged 5.3 times(ranges=4 to 6 times) after the treatment, which showed a big improvement. Conclusion : The sensory integration therapy brought an increase in functional grasp ability along with improvement in daily life functions of the child. For this result, there should be more research to see more effects and results to help those in need.

A novel family of controllable, dissipative structure-dependent integration methods is derived from an eigen-based theory, where the concept of the eigenmode can give a solid theoretical basis for the feasibility of this type of integration methods. In fact, the concepts of eigen-decomposition and modal superposition are involved in solving a multiple degree of freedom system. The total solution of a coupled equation of motion consists of each modal solution of the uncoupled equation of motion. Hence, an eigen-dependent integration method is proposed to solve each modal equation of motion and an approximate solution can be yielded via modal superposition with only the first few modes of interest for inertial problems. All the eigen-dependent integration methods combine to form a structure-dependent integration method. Some key assumptions and new techniques are combined to successfully develop this family of integration methods. In addition, this family of integration methods can be either explicitly or implicitly implemented. Except for stability property, both explicit and implicit implementations have almost the same numerical properties. An explicit implementation is more computationally efficient than for an implicit implementation since it can combine unconditional stability and explicit formulation simultaneously. As a result, an explicit implementation is preferred over an implicit implementation. This family of integration methods can have the same numerical properties as those of the WBZ-α method for linear elastic systems. Besides, its stability and accuracy performance for solving nonlinear systems is also almost the same as those of the WBZ-α method. It is evident from numerical experiments that an explicit implementation of this family of integration methods can save many computational efforts when compared to conventional implicit methods, such as the WBZ-α method.

Amount of biological data information has been increasing exponentially. In order to cope with this bio-information explosion, it is necessary to construct a biological data information integration system. The integration system could provide useful services for bio-application developers by answering general complex queries that require accessing information from heterogeneous bio data sources, and easily accommodate a new database into the integrated systems. In this paper, we analyze architectures and mechanisms of existing integration systems with their advantages and disadvantages. Based on this analysis and user requirement studies, we propose an integration system framework that embraces advantages of the existing systems. More specifically, we propose an integration system architecture composed of a mediator and wrappers, which can offer a service interface layer for various other applications as well as independent biologists, thus playing the role of database management system for biology applications. In other words, the system can help abstract the heterogeneous information structures and formats from the application layer. In the system, the wrappers send database-specific queries and report the result to the mediator using XML. The proposed system could facilitate in silico knowledge discovery by allowing combination of numerous discrete biological information databases.

The objective of this article is to explore the economic relationship between China and the surrounding dynamic Asian economies. It delves into China's influence over the Asian economies and whether this relationship is a market-led or de facto symbiosis. The three principal channels of regional integration analyzed in this article are trade, FDI and vertically integrated production networks. They are essentially based on the activities of the private-sector in these economies. China methodically expanded and deepened its economic ties with the regional neighbors. At the present juncture, China's integration with the surrounding Asia is deep. Another issue that this article explores is the so-called China "threat" or "fear" in Asia. It implies that China is crowding out exports of the other Asian economies in the world market place. Also, as China has become the most attractive FDI destination among the developing countries, it is apprehended that China is receiving FDI at the expense of the Asian economies. These concerns were examined by several empirical studies, and the inference is that they are exaggerated. This article concludes that the private-sector business activities in China and other rapidly growing Asian economies were (and are) instrumental in bringing together the production structures and real economies. The result is both convergence and integration among the dynamic Asian economies. Over the years China and its Asian neighbors has developed a close and symbiotic economic relationship and a de facto regional integration.

In order to overcome social exclusion and to integrate social housing, it is necessary to plan a communal space in urban collective housing so that residents can have belonging sense and community consciousness. In this study, it is necessary to consider the linkage between social integration and residential space, and to derive the characteristics of planning the collective housing for social integration. We analyzed the planning characteristics of MVRDV's communal spaces of collective housing and suggested a method of planning communal spaces of urban collective housing for social integration. Urban density is an important tool and background for MVRDV's design methodology. For this reason, MVRDV's collective housing is selected as a case study in this study. As a result of case analysis, openness and connection characteristics should be considered by using various devices such as glass exterior, balcony, and void in planning the communal space in urban collective housing for social integration. However, since it has appeared in many cases, it can be criticized that the application of this is merely a logic. In other words, it is possible to suggest that we should actively introduce less accessible access. This problem should be solved through more case studies.

The purpose of this study is to explore the secondary mathematics teachers' technology integration self-efficacy with respect to geometry classes which they had experienced during last 1 year, 2015. For this study, we developed and validated the questionnaires based on TPACK framework in secondary geometry context. The questionnaires contained 28 items examining the secondary mathematics teachers' TPACK. We conducted the item analysis with 28 items and then the exploring factor analysis. As a result, 28 items was categorized into 5 constructs, TPCK, TCK, TK, PCK, PK, different from Mishra and Koehler's categorization. We analyzed the secondary mathematics teachers' technology integration self-efficacy with respect to geometry classes based on 5 TPACK constructs. The results indicated that there were no significant differences in technology integration self-efficacy according to gender. But technology integration self-efficacy according to the years of teaching experience differed significantly. The more years of teaching experiences teachers have, the lower level of TPCK and TK they have and the more years of teaching experiences teachers have, the higher level of PCK they have. The results also showed that there ware significant difference in TPCK according to the existence and non-existence of taking the technology courses during the time at university. Furthermore, we provide the implication for the professional preparation program for the mathematics teachers in middle schools.

이 연구는 장애인의 사회통합에 대한 지표와 지수를 개발하고 측정조사함으로써 객관적인 평가와 진단을 제시하는 것을 목적으로 한다. 개발될 지수는 장애인의 생활부문을 조사하여 무리나라 장애문제에 대한 좀더 객관적인 평가와 진단을 제시하는 것이다. 장애 통합지수는 현실을 진단하는 단일수치로 표현되며 이는 우리나라 장애인의 사회통합을 결과의 차원에서 평가하고자 하였다. 장애인 사회통합을 측정하는 하위지표로 장애인 (1) 사회적 태도, (2) 물리적 환경, 고용과 교육 두 가지 하위 차원으로 구성된 (3) 사회적 참여, (4) 제도적 통합 등의 네 가지 차원을 선정하였다. 사회적 태도 차원과 물리적 환경 차원은 관찰조사를 통하여 수행되었으며, 사치적 참여 차원과 제도적 통합 차원은 문헌연구를 통하여 수행되었다. 연구결과, 한국의 장애통합지수는 0.4832로 산출되었다. 따라서 한국의 장애인 사회통합 정도는 48%로 그 궁극적인 목표인 완전 사회통합의 절반 수준이라고 결론내리게 되었다. 그러나 이 연구에서 시도한 장애인 사회통합 지수화는 지표의 측정이나 산출된 지수 값에 대한 해석에 제한점을 안고 있어 향후 지표의 설정과 측정의 신뢰성 부분에서 후속연구가 기대된다.
