The objective of this study is to provide new direction on house design in consideration of the PC users' life pattern. This study found that PC use present conditions at home, demand for PC using space, and requirements for PC using area were analyzed. A survey was taken by 1108 residences, and the SPSS win.10 was applied for analysis. The survey was conducted to see the computer usage at home, demand and satisfaction for the PC using space. The results of this study were as follows; forty-seven percent of respondents said they used the PC in son's and daughter's room while 36.8% answered living room. It reflects that the whole family want to use the PC in the same area, or for their children's convenience. Users' consciousness was analyzed four factor, which were 'physical inconvenience:'satisfactions in PC position', 'inconvenience caused by narrowness', 'notion of privacy'. PC users' consciousness had significant differences in the satisfaction by PC users' characteristic and housing characteristic. It was to be classified that the PC use space into several pattern according to furniture arrangement, and channel pattern had the highest satisfaction among those pattern. Through this study, it is expected that new housing designs need to be made to reflect lese requirements into interior design and house plan for PC user's needs.

In the process of modermization the problem of environment destruction has become a worldwide issue. And now this problem is a concern for all branches of science, including that of architectural desigv. This thesis tries to find the meaning of ecological architectural space, one that encreases the organic relationship, and communication, between architectrual space and urban environmental space, between human beings and architecture, and between human beings and their environment. As an example, we will take a look at the architectural space-design of Frei Otto, who offers diverse creative ecological architectural forms. His concept of architecture has the critical character when compared with the traditionan conventional concept of architecture. The ecological characteristics of his architectural spacedesign can be summarized as follows: The first characteristic is his ample use of natural objects in the architectural structure. An ample use of living things like trees and plants as well as of inanimate thing like water, wind as architectural elements enhances the functional efficiency of architecture. The second characteristic is its ecological architectural system, which saves energy faciliates ventilation by changing the position and direction of the building, by systematically applying the materials, and by efficiently arranging the inner space. The third characteristic is the dematerialization of architecture and the use of materials that are economical and appropriate for the circulation system of nature. The use of natural elements and recycling natural objects, makes it possible to reuse materials of the destroyed building. In short, the ecological architecture of Frei Otto, which shows the relation between human beings and architecture, presents diverse possibilities of the archtectural space as a complex natural system, which is more than a simple combination of separatge elements.

This study was conducted to determine firstly the composition of the essential oil from fresh changpo (Acorus calamus var. angustatus Bess) roots quantitatively and qualitatively by use of two internal standards, and secondly volatile compounds which are primarily responsible for the aroma of changpo roots. Simultaneous steam distillation and extraction method was used for essential oil extraction, and aroma extract dilution analysis (AEDA) and sniffing test by gas chromatography/olfactometry (GC/O) were used to detect the characteristic impact odorants. According to the instrumental analysis of changpo root essential oil, cis, trans-famesol (47.56 mg/kg of fresh wt), octanoic acid (23.73 mg/kg of fresh wt), trans-2-dodecenal (20.28 mg/kg of fresh wt) and trans, trans-farnesol (13.81 mg/kg of fresh wt) were the most abundant compounds. Geranyl acetate, trans-nerolidol and trans, trans-farnesyl acetate were evaluated as the characteristic impact odorants of changpo roots from results of AEDA and sniffing test. Especially, geranyl acetate was considered as the most similar odor component to changpo roots by organoleptic evaluation with GC/O.

Principle of mailing list was distributed messages to all subscribers in one time. But mailing list operation has constructed a network traffic problem. Because mailing list manager distributed mails without concentrate on subscriber network. If our network has many of subscribers, there will be redundant data in traffic channel. Submailing list has purpose to reduce problems. Analyses of mailing list characteristic in electronic mail were a feature of submailing list system, which manage by human hand (Network Administrator). That will cause trouble for network traffic if Network Administrator could not seek for mailing list characteristic from e-mails in due time. This article will present ideas and recognize methodology for automatic working in submailing list system. Recognize step begin with capture process, which use to trap e-mail information from transfer channel. Next process is preparing raw data into recognition format. Then the third one is recognize part and find out confidential factor. The last process is make decision and determine which electronic mail has properties of mailing list characteristic. Afterward deliver result to submailing list for carry on.

Many companies make active use of loyalty programs to improve their customers' loyalty to the company. Loyalty programs are widely used in various industries and sectors, including oil, telecommunications, credit card, department stores, and internet shopping malls; their performance seems to be successful in building a positive relationship with customers. This study emphasizes the role of affiliate programs in creating loyalty, thereby helping companies to maintain their competitive advantage. To objectives of this study are to investigate which antecedent variables(affiliate program benefit, service company characteristic , consumer characteristic) have significant effects on consumer perceived affiliate program satisfaction and to examine whether these factors have differences between Korean and Japanese consumers. The useful results will provide marketing strategy for marketers of service companies. The results also show that affiliate program is very important in order to maintain relationship with customers in service companies.

This paper describes a method for region segmentation and string extractionin documents which are mixed with text, graphic and picture images by the use of the structural characteristic of connceted components. In segmentation of non-text regionas, with connection-characteristic functions which are made by structural characteristic of connected components, segmentation process is progressed. In the string extraction, first we organize basic-unit-region of which vertical and horizontal length are 1/4 of average length of connection components. Second, by merging the basic-unit-regions one other that have smaller values than a given connection intensity threshold. Third, by linking the word blocks with similar block anagles, initial strings are cresed. Finally the whold strings are generated by merging remaining word blocks whose angles are not decided, if their height and prosition are similar to the initial strings. This method can extract strings that are neither horizontal nor of various character sizes. Through computer exteriments with different style documents, we have shown that the feasibility of our method successes.

전방향성을 가지는 다소선으로 만들어진 Biconical Antenna의 특성 임피던스식을 해석적으로 구하고, 이식에 의하여 소선수의 변화가 특성 임피던스에 미치는 영향을 고찰하였다. 이 식은 매우 복잡한 형태를하고, 있으나 정각이 40°보다 작다고 하였을 때 얻어지는 근사식은 매우 간단해지며 이것이 바로 Shelkunoff의 식과 일치함을 볼 수 있었다. 그러나 상기 엄밀식과 근사식에 의한 특성 임피던스의 전자계산치를 비교 분석한 결과 항각이 70° 이하인 범위에서는 양자의 차가 별로 크지 않았으므로 정각이 70°보다 작은 범위에서는 상기의 근사식을 적용할 수 있는 것으로 생각한다.

본 논문에서는 OFDM 시스템에 있어서 심블간 간섭을 일으키는 채널에 대해 lattice 필터를 사용한 등화기의 등화 특성을 검토하였다. Lattice 괼터를 사용한 등화기는 다른 등화기와 비교해서 단수마다의 직교화 효과에 의해, 탭 수가 작아도 수렴이 빠르고 등화 오차를 작게 할 수 있는 특징이 있다. 본 논문에서는 Lattice 필터를 사용한 등화기 필터 계수의 수렴성과 정적인 BER특성을 컴퓨터 시뮬레이션에 의해 해석하고 Transversal 필터 방식에 비해서 우수한 보상 방식인 것을 보인다.
