Aalto designed his own modern architecture in comparison with other modern architects of his days. It is because Aalto went beyond the principle of dogmatic functionalism based on his attitude not to copy images of functionalism but to fulfill function of the building. He decided architectural form and space according to logical basis including the effective use of light and sound. Vuoksenniska church, as is called the most exceptional and notable church in his works, was designed based on the fulfillment of program. As he knew that the program needed the extension of the main church space into social areas, he put emphasis on individuality of space rather than the wholeness of space. Sound and light analysis of Vuoksenniska church shows that Aalto tried to have adequate environment of each space at the start and Integrate them later. The spatial configuration of Vuoksenniska church shows that the individuality of space has priority over the wholeness of spaces. Discordance between roof form and ceiling is the best example for this matter. Aalto designed various windows that have different sizes, figure and location to induce desirable light for each space of the church. He also adjusted the shape of the ceiling and the angle of wall for a effective sound transmission. This result indicates that he knew the activity of the church is normally confined to one weekly morning and the whole space Is hardly used as a religious purpose.

Logistics companies are worrying about securing of differential competitiveness so as to be competitive companies in keen logistics market. The ground is how users are satisfied by sell-established service system to respond not only economic feasibility of logistics costs but also diversity and advancement of logistics needs. The competitiveness of logistics companies is also caused by customer satisfaction of service and only companies finding and satisfying customer needs continuously may be more competitive. For the competitiveness, it's the most important to analyze demands of current and potential customers and their pursuing value properly. Therefore, this researcher grasped PSL for online logistics service users with 5-point Likert-scale and quality-level decision method that consider the weighted value based on Kano model, measured customer's potential Demand for service through PCDI, and suggested methodology for deciding the priority of the improvement with loss function of Taguchi.

The purpose of this study was to measure employee ‘awareness’ and ‘practice’ of business ethics in the foodservice industry, and to determine possible correlations between these two variables. Self administrated questionnaires were completed by 1003 employees and data were analysed to ascertain frequency, factor, reliability, correlation and canonical correlation. Two factors were obtained from factor analysis of business ethics(BE) awareness; “Organizational awareness”, and “Individual awareness”. Similarly, two factors were also obtained for business ethics practice; “Systematic practice”, and “Compensatory practice”. Canonical correlation analysis produced two significant functions. For canonical function 1, it was found that organizational awareness of BE was positively correlated with systematic practice. For canonical function 2, it was found that individual awareness of BE was negatively correlated with the compensatory practices of BE. The findings of this study demonstrate that higher organizational awareness of business ethics in the foodservice industry led to higher systematic practices of BE, while higher individual awareness of BE led to lower compensatory practices of BE. In conclusion, higher organizational awareness of BE places a higher priority on building an external system from an institutional perspective, while higher employees awareness of BE leads to higher expectation from the company, resulting in relatively low compensatory practices.

기존에는 댐사업의 생활용수 공급편익 산정시 실무적으로 대체댐비용법을 적용하였다. 그러나 해당 댐의 대체시설로서 2순위의 댐을 적용하는 것은 논리적으로 적절하지 않다. 본 연구의 목적은 생활용수 공급사업의 효과에 대한 소비자의 효용을 지불의사액으로 측정하고, 수요함수를 도출하여 편익산정 방법을 제시하는 것이다. 이를 위해 수도권지역에서 1,000가구를 대상으로 생활용수의 사용량 변화에 대한 한계지불의사액을 측정하였다. 그리고 한계지불의사액을을 이용하여 가구별 수요함수를 추정하고, 최종적으로 용수공급 사업의 경제성분석에 적용할 수 있는 월평균 편익산정식을 도출하였다. 제시된 방법론은 적용방법 설명과 토론을 위해 예제로서 송리원댐(현 영주댐)에 적용하였다. 예제 적용 결과, 내용연수인 50년간 총 편익은 약 900억원으로 산정되었다. 본 연구에서 제시된 방법론은 향후 관련 연구 뿐 아니라, 댐 건설사업을 비롯한 생활용수 공급사업에서 경제성분석시 실무적 활용이 가능할 것으로 기대된다.

The purpose of this study is to examine the change of inner roads responding to the street system and to examine the how to influence to communal space of village focused on 22 existing old settlements in downtown Cheong Ju. This study examined the types of inner roads based on advanced research. For the research on communal space, interviews with the residents living in the village were conducted to figure out the location and function of it. Also, it was analyzed comparatively with the present communal space. The results are as followings: the width of an inner road has a effect to function of an inner road when flow of an inner road has kept. The function of inner road has been kept when the width of an inner road expanded as pedestrians should be given priority to vehicular traffic. However, the function of inner roads has been changed and the community has been separated when the width of inner roads expanded for vehicular. Because the location of the communal space in the village is affected by the change of the inner road, when the inner road is maintained, the location of the communal space is also maintained, but when the inner road is changed, the location of the communal space is also changed. The communal spaces such as public wells and wash spaces have lost and they have been substituted with senior citizen centers or community centers.

An efficient modified $D^*$ lite algorithm is suggested, which can perform online path planning for mobile robots in dynamic indoor environment. Online path planning should plan and execute alternately in a short time, and hence it enables the robot avoid unknown dynamic obstacles which suddenly appear on robot's path. Based on $D^*$ Lite algorithm, we improved representation of edge cost, heuristic function, and priority queue management, to build a modified $D^*$ Lite algorithm. Performance of the proposed algorithm is revealed via extensive simulation study.

This paper describes the design of a high-level synthesis system. SODAS-VP. which automatically generates hardwares executing operation sequences in pipelined fashion.Target architecture and clocking schemes to drive pipelined datapath are determined, and the handling of pipeline hazards which degrade the performance of pipeline is considered. Partitioning of an operation into load, operation, and store stages, each of which is executed in partitiones control step, is performend. Pipelinecl hardware is generated by handling pipeline hazards with internal forwarding or delay insertion techniques in partitioning process and resolving resource conflicts among the partitioned control steps with similarity measure as a priority function in module allocation process. Experimental results show that SODAS-VP generates hardwares that execute faster than those generated by HAL and ALPS systems. SODAS-VP brings improvement in execution speed by 17.1% and 7.4% comparing with HAL and ALPS systems for a MCNC benchmark program, 5th order elliptical wave filter,respectively.

Automated Guided Vehicles are widely used as an essential material handling system for FMS to provide flexibility and efficiency. We suggest a new dispatching rule based on priority function which considers urgency and empty vehicle travel time under finite buffer capacity. We evaluate the performance of the proposed rule by comparing the performance of Shortest Travel Time/Distance(STT/D) rule in terms of machine utilization, throughput and WIP level using simulation. The simulation results show that the suggested dispatching rule is robust and provides better machine utilization, throughput with comparable WIP level compared to STT/D rule.
