최근 매우 빠른 속도로 축적되는 생물학적 데이터를 효과적으로 제공하기 위한 연구들이 활발하게 진행되고 있다. 하지만 기존 연구들은 단순하게 데이터를 수집하고 향후 연구에 활용하기 위한 데이터베이스 구축을 중심으로 진행됐다. 따라서 본 논문에서는 분자마커 등에 대한 데이터베이스의 구축으로 생성한 원천 정보에 대한 효과적인 검색 및 데이터 분석을 제공하기 위해, 고추 분자 마커분석을 위한 웹 서비스를 설계하고 구현한다. 고추 분자 마커 분석을 위한 웹 서비스는 웹 기반 사용자 인터페이스를 이용하여 고추분자 마커에 대해 손쉽게 접근할 수 있는 인터페이스를 제공하며, 사용자에게 분석된 분자 마커에 대한 상세 정보를 제공한다.

Although the entrance of house has been identified as a hotspot for older adults' fall accidents, there was not any lift chair to prevent older adults' accidents. In this study, a lift chair was developed to reduce fall accidents that can occur when older adults put on or take off their shoes in the entrance. In order to develop the product, we considered two aspects. Firstly, we considered older adults' anthropometric data to determine the design specification of the product. Also we considered the environmental characteristics of space using the product. In order to overcome the limited spatial freedom and use the entrance space effectively, we took a simplified and folding type for the product.

The objective of this study is to analyze the static and dynamic characteristics of automotive rubber components by computer simulation. Bush / rectangular type engine mounts and wind shield weather strip are analyzed by using the commercial code ABAQUS and the results are verified by experiments. Large deformation static response is analyzed in order to get the information about the deformation pattern and static stiffness of engine mounts, and about the seperation force of wind shield weather strip from body. The isothermal steady-state dynamic response of components which have been subjected to an initial static pre-load is analyzed for the dynamic stiffness of engine mount rubber components. There are good agreements between simulation and experiments. So it is possible to apply the computer simulation to the design of automotive rubber components.

한계기업은 성장가능성이 있는 기업들에게 돌아가야 할 자금 및 지원정책을 기업의 연명수단으로 전략하게 될 가능성이 있어 비효율적 자원배분을 초래하게 되며 이는 궁극적으로는 경제성장의 제약을 유발하게 된다. 따라서 본 연구에서는 뉴스 데이터를 활용하여 이러한 한계기업을 초기에 탐지할 수 있는 방법을 제안하고자 한다. 연구결과, 뉴스 데이터를 활용하였을 경우, 그렇지 않은 경우보다 모든 지표가 우수한 것으로 나타나 실제적인 문제에서의 적용 타당성과 가능성을 보였다. 이를 통해 기업은 부실화된 정도를 사전에 예측하여 경영 전략 재수립을 위한 지표로 활용할 수 있을 것이며, 투자자는 리스크를 관리할 수 있는 수단으로 활용될 수 있다.

Value Engineering(VE) is an organized effort to create the most value through a functional analysis and creation of alternatives. Depending on the VE job plan, a VE Workshop must be performed in a certain place within a certain period of time. A VE Workshop, which is an organized activity that aims to create the best value through functional analysis and creation of alternatives, should be held in a certain place and at a scheduled time according to the VE job plan. In the Pre-Study, VE Study and Post-Study phases of VE, functional assessments, performance evaluations and idea evaluations are driven by variable management techniques and analysis methods, respectively. Generally, VE is executed for about 3 to 5 days in a particular place to create value. However, there are many problems associated with limiting all VE processes to a specific place and schedule. Moreover, in Korea, VE teams are required to finish all VE processes in a limited time because of the short duration of VE workshops, the necessity of which has been overlooked. Therefore, an efficient VE support system is required to resolve the problem of time and space limitations. In this study, a VE support system based on the Mobile environment was developed to support the VE Workshop process. This VE support system enables participants to review design documents, drawing sheets and all VE-related documents using mobile devices. After the Workshop, participants can conveniently rearrange the result(evaluation of function and ideas) at the workshop. Not only can the members of VE team can review the design documents, drawing sheet and all VE-related documents in the step before the workshop, but also the result(evaluation of function and ideas) of the workshop can be easily rearranged in the phase after the workshop under the developed supporting system using mobile devices.

The purpose of this study is to identify the factors which affect the customer value and satisfaction of public information services used by the researchers in SMEs(small-and-medium size enterprises). The results, based on statistical analyses of a survey conducted in Korea are as follows; 1) the customer value is positively influenced by the service quality; 2) the customer value, in turn, is positively associated with the customer satisfaction; 3) information needs moderate the relationship between service quality and customer value but does not moderate the relationship between the customer value and satisfaction.Our findings propose the importance of the service quality and the effort to maximize the information customer values.

Experimental studies on the effects of impeller to provide the microbial transglutaminase derived from Streptoverticillium mobaraense have been conducted. The optimal production medium was determined by latin-square design, and the effects of aeration and agitation were observed by using different sizes and shapes of impellers for the poduction of transglutaminase. The effects of pH and temperature were also evaluated for the production of transglutaminase in flasks. As a result, pH is more effective than temperature for both enzyme production and growth of the microorganism. The peak enzyme activity for transglutaminase in fermenter was 0.7 U/mL, but this was still well below the avereage enzyme activity, 1,3 U/mL, obtained in flask runs.

In case of the hydraulic turbine dynamo room at Dam, due to its big volume and reflexible finishing material, since the noise of electricity-generation is amplifying, it influences the difficulty of mutual communication among the workers, also it is causing both mental and physical damages to those workers in the neighboring office. Accordingly, after presentation of the optimized renovation model of the hydraulic turbine dynamo room using the acoustic simulation, this Research has compared and evaluated them using the auralizational technique between the present condition of "before improvement" and the acoustic condition of "after improvement". As the result of psycho-acoustics experiment, as the acoustic conditions at both "before & after Improvement" were apparently compared, it appeared that there is a considerable amount of noise-reduction effect at psycho-acoustics. It is considered that such material could be utilized as the valuable data hereafter for the time when any construction and renovation of the hydraulic turbine dynamo room and other similar workshop.

Even though Waterpower Generation as pollution-free has its own merit of contribution by supply of good quality electricity, due to the noise made at the time of its operation, a normal mutual communication among the workers and technicians engaging at the hydraulic turbine dynamo room is almost impossible, and since those finishing materials had been used mainly by reflection material, it is actual situation that when working for maintenance in the hydraulic turbine dynamo room, as counterpart's voice vibrates, its working efficiency is difficult to ensure. On such view point, this Research has conducted Psycho-acoustics Experiment about voice Definition using Auralizational Technique, on the object for the hydraulic turbine dynamo room that improved its acoustic performance by computer simulation. As the result of Study, it was known that the clearness of sound with regard to voice information transmission was apparently improved in all items than before improvement. Therefore, it is considering that these results would be utilized usefully when renovation on the hydraulic turbine dynamo room in the future.
