In television stereo system, to produce a realistic sound effect is very difficult because the distance between stereo speakers is very narrow. Many signal processing methods of widening the sound image for spatial impression have been studied. One of the methods of widening the sound image is using the Precedence Effect by reflected sound. However, this method does not work effectively in lower frequencies because of directivity of a speaker. In this paper, we propose an effective method of expanding stereo image using Precedence Effect and Phase Shifting method to produce a whole band frequency sound expansion. In experiments, we confirm the usefulness of the proposed stereo sound image expansion system.

The purpose of this paper is to investigate the customer's requirements for shoe products using the survey method, to analyze customers' needs, and to supply information to make the shoe that they want. For this work, we made 38 survey items for the degree of shoe satisfaction, for foot care and shoe control, for shoe characteristics, and for shoe purchase in future. For the purchase of shoe products in future, customers in their twenties gave the highest score for shoe design among price, design, size, fashion, fitness, color, brand, so forth. However, respondents in their forties selected the degree of fitness instead of shoe design. In the question for the buying price of shoe products in future, all customers wanted shoe products between 30,000 won md 50,000 won.

In order to achieve the most suitable designing of shoemaking, the structure of shoemaking is described in this study by inquiring into structural and functional effects given by shoes to human feet. Also, the role of insole that is an essential portion in view of function in shoemaking is described and. for the improvement of quality the fact that selection of material of insole has an effect to quality is substantiated through experiments of adhesive tensile and absorption percentage. Though identification of the qualify of insole with the naked eyes is impossible because it is inserted between the internal layers of a shoe. It is not only an essential portion for the improvement of the quality of shoemaking but it gives an essential effect to the sanitation and health of human body(feet) when insole of lower qualify is used. In view of these the improvement and enhancement of the quality of home-made material of insole are earnestly required.

내연기관은 일찍이 군용과 특수용도는 물론, 최근 서민생활에 직결되어 널리 사용되고 있으며, 일상생활의 필수기계가 되어 놀랄만한 수의 엔진이 생산, 사용되기에 이르렀다. 그러나 한편으 로는 그것을 사용함으로서 사람들에게 해를 준다는 문제가 발생하였다. 특히 주위 사람들의 건 강을 해칠 우려가 있는 유해성분을 포함한 가스의 배출, 또는 소음의 발생이 큰 사회적 문제가 되어 그 방지대책이 종래의 성능향상에 대신하여 지상명제로서 연구 개발되고 있다. 이에 대한 대책은 일반적으로 엔진의 가격과 성능을 희생시키는 것은 불가피하지만, 그것은 최근 세계적인 위기로 불리는 에너지와 기타 자원의 절약과 상용할 수 없으므로 이러한 공해와 자원이 양 립할 수 있는 방향으로의 새로운 내연기관 연구가 강력하게 요망되고 있는 것이 현상태이다. 엔진이 인체에 해를 줄 가능성이 있다는 것은 이전부터 알고 있던 바이다. 예를 들면 좁은 실 내나 터널중에서 운전하면 많은 량의 산소를 소비하기 때문에 단시간에 산소가 부족하게 될 뿐만 아니라, 일산화탄소 함유량이 많은 배기를 배출하게 되어 인체에 중대한 해를 준다. 그러나 이와 비슷한 일이 전도시적인 문제가 되어 법규제가 된 것은 최근의 일이고, 배출가스에 대하여서는 미구에 의하여 약 10년 전부터 자동차의 배기규제가 계획되어 금일 진행중이다. 또 소음에 대 하여서는 오히려 극히 초근부터 법규제화가 진행되고 있으나 어느 쪽도 사회의 요구를 완전히 만족시킬만한 대책기술은 용이하지 않다.

This study was conducted to analyze the medical charges of the elderly dementia inpatients, to identity their characteristics, and there by to evaluate feasibility of the per diem payment system for the patients. Data on medical charges of the patients were collected from the National Federation of Medical Insurance and sample hospitals from October through December 1997. The data were analysed in order to find the characteristics and test hypotheses postulated. The results are summarized as follows; Firstly, there was no difference statistically in between disease groups and between the dementia inpatients belonging to each disease group. Secondly, the amount of the non-insurance medical charges of the elderly dementia inpatients is considerably high compared to the insurance medical charges paid by the patient, which implies that some measures are to be prepared by the Government. Finally, medical charges per inpatient day of the dementia patients are not different statiscally by sex, by age group, and by disease group. This result supports the feasibility of the per diem payment system for the elderly dementia inpatients.

소프트웨어 생명주기 중 가장 많은 비용이 유지보수 개발에서 발생한다. 대형 소프트웨어 시스템의 운영 유지보수 표준은 ISO/IEC 20000 으로 프로세스통합운영 및 개선활동 중심이어서 유지보수 개발에 대한 SR(Service Request) 처리시 개발 표준 및 구체적 절차가 미비하다. 그러나 대형 소프트웨어 시스템 구축 개발 시 많이 채택하고 있는 CMMI-DEV 표준을 ISO/IEC 20000 유지보수 조직 및 팀원이 내제화를 함으로써 유지보수 개발의 상호 보완적 프로세스로 명세 명확화 및 품질을 제고할 수 있고, 생산성과 효율성을 증대할 수 있다. 따라서 본 연구에서는 ISO/IEC 20000 유지보수 조직이 운영하고 있는 표준절차에 CMMI-DEV 표준 프로세스를 상호보완적으로 매칭한 표준절차를 적용한 통합모델을 제안한다. ISO/IEC 20000 모델의 개발단계에 CMMI-DEV 프로세스 모델을 적용한 통합 모델을 구축하고 실제 프로젝트에 적용하여 본 연구의 실효성을 검증한다.

The shoe last which is the framework for the shoemaking is intensively combined with the 3D data and technologies. International shoe companies have already commercialized 3D printing technology in producing the shoe, but domestic shoe companies are still in their early stages. This study used the 3D scanning, 3D modeling and 3D printing of the high-technology to make the shoe last. This 3D producing processes should be helpful in building competitiveness in domestic shoe industry. The 3D foot scanning data of men in 30s(n=200) were collected in SizeKorea(2010). The basic statistics, factor and cluster analysis were performed. They were categorized in 3 groups by 3D foot measurement data, and the standard models were selected in each group. The cross sections in XY, YZ and XZ planes sliced from 3D scan data of the standard model were used in the sketches of the 3D shoe last modeling. The 3D shoe last was modeled by Solidworks CAD and printed by MakerBot Replicator2; a desktop 3D printer. This research showed the potential for utilization of 3D printing technology in the domestic shoe industry. The 3D producing process; 3D scanning, 3D modeling and 3D printing is expected to utilized widely in the fashion industry within the nearest future.

This study has investigated the status and overview of design characteristics of customized shoes, which receives much recognition at domestic and overseas markets. Based on the market research on current consumer lifestyle and needs of the custom-shoes(which is an abbreviation of customized shoes), this study has provided its development directions, views and demands. The design types of custom-shoes have been broadly divide into two: firstly 'style centered custom-shoes'; secondly 'function centered custom-shoes'. Style centered custom-shoes are specifically divided into 3 types; first, formal custom-shoes; second, sports and casual custom-shoes; and lastly, bespoke shoes. Function centered custom-shoes design refers to enhancing the function of personal soleprint which has to be designed by delicately detailed insole and outsole, rather than alignment of exterior parts of the shoes. These are used in professional sports shoes and also include orthopedics footwear and grafted footwear for people who have disabled on foot. Custom footwear market has been highly expanded and has entered value-added market according to increasing interest in foot health and shopping trends on shoes buying like taking shoes as personal expression in accordance with a variety of places and situations. In the near future, custom-shoes can be produced in a couple of days due to the technological advance of 3D scanners and 3D printers. This phenomenon will wants more demands of specific shoes experts such as custom-design consultants or shoes fitting experts, who can overcome limitations of online custom-shoes stores.

In this paper, I examined two things. First explore the of the reality(眞) in poems written on paintings and discussion on paintings in men of letters of Pre-chosun dynasty, furthemore, it analyzes the meaning and thought. To explain it, I would like to analyse the discourse surrounding the reality(眞) in poems written on paintings and discussion on paintings, and concept of the borrowing(假) and the unreal(幻). First of all, I examine the ways that the view of nature of Confucians is pertinent to the abiding in reverence and the investigation of principles of confucians, also painting is necessarry condition for their moral and spiritual self-cultivation. In the discourse surrounding the reality, it is to suggest from 'natural reality (天眞)' to escape from the reality(眞), and proceeds to examine the transformation of reality(眞) in mind(人心). Furthermore I examine the meaning of transform and delicate difference between borrowing(假) and the unreal(幻). In this process, concept of the borrowing(假) and the unreal(幻) is divided into the two meaning. False(假) is to become the Borrowing and painting, the unreal(幻) is change into the act of recognition. In conclusion, I examined the significant transformation of the reality(眞) and the unreal(幻). The reality(眞) has been recognized as a important concept, it is diverged into the Nature, outer things and painting mind, and the object of ultimate value in appreciation and painting of Pre-chosun dynasty.
