The cultural identity of each nation has appeared as a major issue in this multi-cultural era, and needs to define It clearly through comparisons with other cultures have been raised. The purpose of this study is to figure out ‘similarity’ and ‘dissimilarity’ on design characteristics of traditional storage furniture in interior context of Korea, China and Japan. Comparative analysis of traditional furniture was conducted in two terms, in terms of inner space, first, spatial elevation and front patterns, second, flooring materials of the interior space and types of furniture legs. Result of first comparative analysis showed that composition of windows, one of the major decorative elements of interior space, positively influenced on furniture, and reflected unique patterns of each country. Second comparative analysis showed that structures and shapes of traditional furniture vary depending on flooring materials. As a result of it, Korean furniture has the structure of ‘punghyeol’ and Chinese furniture has the structure of ‘aja’ with ‘takni’ , a combination of legs. In contrast to the two countries, Japanese furniture has rarely legs. The result of analysis is expected to act a role of establishing the cultural identity of our own country.

The past several years have witnessed an ever-increasing acceptance and adoption of parallel processing, both for high performance scientific computing as well as for more general purpose applications. Furthermore with increasing needs to perform the complex flow calculations in an efficient manner, the use of the message passing model on distributed networks has emerged as an important alternative to the expensive supercomputers. This work attempts to provide a generic framework to enable the parallelization of all CFD-related works using the master-slave model. This framework consists of (1) input geometry, (2) domain decomposition, (3) grid generation, (4) flow computations, (5) flow visualization, and (6) output display as the sequential components, but performs computations for (2) to (5) in parallel on the workstation clustering. The flow computations are parallized by having multiple copies of the flow-code to solve a PDE on different spatial regions on different processors, while their flow data are exchanged across the region boundaries, and the solution is time-stepped. The Parallel Virtual Machine (PVM) is used for distributed communication in this work.

Stress induces change to the body functions and causes chronic problems such as worsening a disease. Thus, humans want to evade anxiety and would try any means to reduce stressful situations. Generally, a person would handle their stress by either regulating their emotions or merely coping with the situation, for which the former is most widely used. Our research aims to effectively reduce stress by using the emotional response structure developed by Plutichik and the vitalization method. We extracted the relevant components of the stress-reduction method that would be applicable in any space using digital technologies such as sensors, IoT, and augmented reality. An architect or designer may incorporate these structural components into any structure to effectively reduce people's stress. The research aims to provide a new perspective of architectural space and to show applications of the stress-reducing architectural spaces, which should also fulfill the people's needs. Further research is needed to develop an automatic system to utilize spatial components more effectively.

본 연구의 목적은 GIS를 이용하여 TMS측정망의 적정성을 분석하는데 있다. 대기오염자료를 이용하여 TMS 분포의 적정성을 분석한 결과 TMS 주위의 토지이용상태가 변화했음을 알 수 있었다. 토지이용상태에 따른 분포의 적정성을 분석한 결과 현재 대부분의 측정소가 주거지역에 설치되어 있음을 알 수 있었다. 따라서 TMS의 재배치 및 추가적인 설치가 필요함을 알 수 있었다. 기존의 TMS를 적절한 위치에 이전하고 인구밀도에 따른 차등배분방법을 사용할 경우 추가적으로 설치해야 할 측정소의 수를 최소화 할 수 있음을 알 수 있었다.

동체의 3차원 순간위치결정을 위해서는 동일시간에 획득한 2개 이상의 영상이 필요하다. 최근 대중화되고 있는 디지털 카메라를 이용할 수도 있겠으나 연속영상은 얻을 수 없으므로 본 연구에서는 이를 위하여 비디오카메라를 이용한 저가의 순간영상획득시스템을 구축하였다. 또한 동일한 시간대의 입체영상을 얻기 위하여 LCD타이머를 동체와 함께 촬영하고 얻어진 연속영상으로부터 비디오 편집기를 이용하여 독립수치영상을 얻었다. 그 결과 동일시간의 수치영상을 $788{\times}550$픽셀의 해상도로 얻을 수 있었고 1/100sec의 시간정확도로 획득한 동체상의 타겟을 검사 한 결과 양호하였다. 추후 3차원 위치정확도를 비교하기 위해 일반 측정용사진기로 B-shutter를 이용하여 동체를 촬영, 양호한 음화를 획득할 수 있었다.

This study identifies the necessity and importance of innovation in rural communities and highlights the role of rural revitalization support centers in facilitating the diffusion of community innovation. The study provides a literature review and employs the survey method to verify the arguments. There is an urgent need for rural communities to be distinct, attractive, and competitive in the wake of globalization. It is clear that they must recognize the need to facilitate innovation under growing trends toward trade liberalization, environment-oriented life styles, diversified consumer needs, and a knowledge-based society. The results provide support for the legitimacy of establishing rural revitalization support centers to help community leaders and local stakeholders develop their communities. More specifically, rural communities should employ R&D outcomes from diverse fields and capacity building by community members, leaders, and local governments to foster sustainable growth by overcoming limitations in spatial access and resources. The results suggest that rural revitalization support centers can be established as intermediary organizations that can be operated to facilitate community innovation in rural development. In addition, these centers should play key roles such as empowering communities, facilitating region-specific rural development policies, motivating R&D applications for rural development, encouraging rural development networks. Further, close attention should be paid to facilitate mutual learning by expanding networks and interactions between these centers.

This paper introduces the double-density discrete wavelet transform using 3 direction separable processing method, which is a discrete wavelet transform that combines the double-density discrete wavelet transform and quincunx sampling method, each of which has its own characteristics and advantages. The double-density discrete wavelet transform is nearly shift-invariant. But there is room for improvement because not all of the wavelets are directional. That is, although the double-density DWT utilizes more wavelets, some lack a dominant spatial orientation, which prevents them from being able to isolate those directions. The dual-tree discrete wavelet transform has a more computationally efficient approach to shift invariance. Also, the dual-tree discrete wavelet transform gives much better directional selectivity when filtering multidimensional signals. But this transformation has more cost complexity Because it needs eight digital filters. Therefor, we need to hybrid transform which has the more directional selection and the lower cost complexity. A solution to this problem is a the double-density discrete wavelet transform using 3 direction separable processing method. The proposed wavelet transformation services good performance in image and video processing fields.

According to the increase of rural experience, that is important in satisfying needs of green tourism and vitalizing rural economy to use closed school in rural area as experience facility. For using closed school as experience facility, political and institutional assistants are needed in effective equipments and stable operation based on multi-perspective approach and analysis. In this study, we try to evaluate green-tourism accessibility of rural experience facility remodeled from closed school considering regional population and spatial characteristics. In evaluating process, gravity potential model are adapted with considering group size of customer and distance-friction coefficient. Distance-friction coefficient is a function of user restriction which depend on possible activity in each experience facility. Green tourism accessibility of experience facility is calculated with summation of accessibility to each region, and we analyzed it as a group by closed school type and location with application in Chungcheongnam-do. We found a correlation between green tourism accessibility of rural closed school and their income.

Water quality modelling is an ideal tool of simulating physical, chemical and biological changes occurring in water systems. It has been utilized in a number of GIS-based water quality management and analysis applications. However, there is a need of a decision making process to translate the modelling result into an understandable form thereby implement the modelling results to the real world. This paper outlines a new water quality index called the QUAL2E's water quality index (QWQI) based on the water quality modelling using QUAL2E. The development mainly includes four steps: variable selection, sub-index development, weight assignment and sub-index aggregation. An experiment of applying the index and GIS to the Sapgyo River in Korea was implemented. Different from other water quality indices for general water uses, the index is specifically used for the simulated water quality indicators. The index can provide a simple and easy-to-understand decision support. Furthermore, interfacing with GIS, the decision analysis can be performed within a spatial environment. However, more study needs to be made in the future including the improvement of aggregation function.

Structural vibration induced by excitation forces under turbulent boundary layer is investigated in terms of the numerical analysis in this paper. Since the responses of structures excited by the wall pressure fluctuation(WPF) are described by the power spectral density functions, they are calculated and reviewed theoretically for finite and infinite length beams. For the use of numerical approaches, the WPF needs to be discretized but conventional finite element method is not much effective for that purpose because the WPF lose the spatial correlation characteristics. As an alternative numerical technique for WPF modelling, a wavenumber domain finite element approach, called waveguide finite element method, is examined here for infinite length beams. From the comparison between the numerical and theoretical results, it was confirmed that the WFE method can effectively and easily cope with the excitation from WPF and hence the suitable approach.
