  • 기존의 임베디드 시스템은 Intel x86 계열의 CPU를 장착한 PC(Personal Computer) 플랫폼에 기반하여 구현되었는데, 이는 PC 환경에서 개발된 많은 솔루션들을 이용할 경우 전체적 인 제품 개발 기간을 단축할 수 있을 뿐만 아니라 제품의 신뢰성을 높일 수 있기 때문이다. 또한 PC 플랫폼 기반의 임베디드 시스템은 데이터 저장을 목적으로 하는 경우가 많아 주로 대용량 하드디스크를 데이터 저장장치로 사용한다. 최근 하드디스크의 용량은 빠른 속도로 증가하고 있는 반면에 하드디스크의 구동 준비 시간이 30초 이상으로 길어지는 문제점이 발생하고 있다. 길어진 하드디스크의 구동 준비 시간은 시스템의 부팅 시간에 영향을 미쳐 전체 시스템의 부팅 시간이 길어지고 사용자의 불편함을 가중시키게 된다. 본 논문에서는 대용량 저장장치를 지원하는 PC 플랫폼 기반의 임베디드 시스템에서 리눅스 커널이 빠른 부팅을 수행할 수 있도록 개선된 시스템 구조와 동적 디스크 장치 검사 기법을 제안하고, 성능을 평가하여 제시한다.

  • Although ready meals have recently increased their market share in the Korean food industry, a literature review found that the use of ready meals triggers feelings of guilt in homemakers. Such guilt arises as a result of several factors apparently related to consumers' health. Consequently, levels of guilt might be expected to vary depending on consumers' perceived health locus. The present study aims to examine (a) how health locus affects guilty feelings about ready-meal consumption, (b) how the effect varies in relation to the consumption of different types of ready meal, and (c) the relationship between consumers' guilty feelings and willingness to buy ready meals. Three dimensions of health locus of control (HLC) -internal HLC (IHLC), powerful-others HLC (PHLC), and chance HLC (CHLC)- were presumed to influence consumers' feelings of guilt in association with ready meals. Data were collected via an online survey, and participants were randomly assigned to either of two groups: one group was instructed to heat meals in a microwave (ready-to-heat [RTH] group, n=104) and the other cooked using a pan with additional ingredients (ready-to-cook [RTC] group, n=101). The study found that guilty feelings about consuming RTH meals increased in line with increased external HLCs, namely, PHLC and CHLC. For the RTC group, guilt increased in line with increased PHLC. IHLC had no significant effect on guilty feelings in either group. Willingness to buy ready meals decreased for both groups as consumers' feelings of guilt increased. Even RTC meals, which require more time and energy in food preparation, did not reduce guilty feelings among consumers with higher PHLC. RTC meals are preferable for consumers with higher CHLC, since their sense of greater involvement in the cooking process alleviates their feelings of guilt. Cooking with already prepared and uncooked ingredients brought fun and joy, both for the participants and their significant others. This interpretation may be developed into a strategic plan by ready-meal producers to strengthen their marketing strategy.

  • The purpose of this study was to identify the characteristics of consumers who purchase home meal replacements (HMR) and to analyze the differences for frequency of use, preference, satisfaction, and repurchase intention based on HMR product categories. The subjects were adults in their twenties or older, who had used HMRs and lived in Seoul and the Gyeonggi Province of Korea. Five-hundred and fifty subjects were chosen by random sampling, and questionnaires were distributed from March 12 to 30, 2005. A total of 451 questionnaires were returned (the rate of return was 82%). The primary results of the study are as follows. First, by analyzing for differences based on the demographical characteristics of the HMR consumers, men had higher 'frequencies of use' and preference, whereas women had higher satisfaction and 'intentions to purchase again.' This implies that HMRs assist women who are usually in charge of home food preparation, based on time and cooking effort; hence a higher satisfaction among the women. Second, by analyzing for differences based on the characteristics of HMR consumers who ate the products, 'frequency of use' (p<.001), preference (p<.01), satisfaction (p<.001), and 'intention to repurchase' (p<.001) for the 'ready to eat' HMR category, by the person who prepared the food, were significantly higher for those subjects in their 20s than for those in other age groups. As for persons influenced by the meal, the teen age group had significantly lower 'frequency of use'(p<.001), preference (p<.05), satisfaction (p<.01) and 'intention to repurchase' (p<.01) than other age groups. 'Frequency of use' (p<.001) and preference (p<.05) were lower if the person influenced by the meal was one's spouse or child than if the person influenced by the meal was oneself. Third, regarding the preference for eating at home or eating out, 'frequency of use' was significantly higher than the other analyzed factors for the 'ready to eat,' 'ready to heat,' and 'ready to end-cook' HMR categories. In short, the 'frequency of use' for HMRs was higher for those who preferred to eat at home versus eating out, simply as a result of being bored with eating out, which is essentially the reason for the origin of HMR.

  • Whole amount of waste water, approximately 921.6 liter, for cleaning a ready mixed concrete truck should be used to produce concrete as a mixing water or cleaning water. Recycling water for concrete mixing contains solids, which cause decrease in slump, air and compressive strengths, so it may influence on poor concrete quality. Therefore, it has been maintained to use recycling water with less than 3 percent of solids. Since no evaluation system has been constructed to directly reflect on variability of recycling water from ready mixed concrete plants, it is necessary to develop "Automatic recycling solid measuring system" for quality controls in real time. In this research, sensors measuring waste water concentration in ultrasonic and inductance methods were developed, and automatic system using the sensors were established. The accuracy of measurement sensors developed for recycling water based on various conditions of concentration was proved, and application limits were evaluated. Also, concentration of recycling water using sensors developed from ready mixed concrete plant was measured, and curing method verified the accuracy of the sensors. Moreover, measurement sensors for recycling water in various locations were installed to evaluate the effects on measuring method and spots. The automatic measuring system for recycling water concentration, which is developed in the research, will contribute to improve concrete quality safety through reliable solids maintenance.

  • Men's clothing has been recently giving higher market shares to the ready-made clothes rather than the custom-tailored clothes. With many active studies on the human body and design, the ready-made clothes win popularity due to their rapid repairing, various design, and cheap prices, though they are not perfect suitable for some people. Therefore the ready-made has a weak point unable to consider all of the individual physical characteristics. However the custom-tailored clothes ate able to make clothing perfectly suitable lot their customers, though they require longer time-taking and expensive costs. In this context, this paper is design and implementation an automatic design edit system to provide a rapid and cheap service for customers on the ground of the custom-tailored clothes. In other words, this paper intended to use computer systems lot rapidly and precisely providing design dependent on the individual physical characteristics including a distorted bodies, types of the leg, and a height of the shoulder. To do so, the paper using not only studies on the human body and the custom-tailored clothes but also technical know-hows planned design for each individual body by LISP language and automatically process the design through CAD system. Consequently, the rapid and precise processing has reduced inventories and production costs, leading to supplying high quality clothes at lower prices.

  • 본 논문은 최근에 많이 사용되는 정형 계산 모델 중 하나인 hierarchical FSM (HFSM)과 synchronous dataflow (SDF) 모델(줄여서 HFSM-SDF)을 이용한 재구성 가능한 SoC 설계에서 실시간 구성 스케줄링(configuration scheduling) 방법을 제시한다. HFSM-SDF 모델을 이용한 재구성 가능한 SoC 설계에서는 HFSM이 갖는 동적인 특성들(예를 들면, AND 관계에 의해 동시에 일어나는 state transition, HFSM이 갖는 복잡한 control flow, 그리고 그에 따른 SDF actor firing의 복잡한 스케줄등)로 인해 구성 스케줄링이 어려운 일이 된다. 그리고 이러한 동적인 특성들로 인해 정적인 구성 스케줄링 방법을 이용해서는 구성에 의한 지연(configuration latency)을 적절히 감추는 것이 어렵다. 본 논문에서는, 이 문제를 해결하기 위해, 실시간에 정확한 구성 순서를 찾은 후, 이를 이용한 동적인 구성 스케줄링 방법을 제안한다. 우선, 실시간에 필요한 구성 순서를 찾기 위해서는, HFSM-SDF 모델이 갖는 특징, 즉, SDF actor들의 실행 순서(firing schedule)는 최상위 FSM state transition 직전에 알 수 있다는 점을 이용할 수 있다. 이렇게 최상위 FSM의 매 transition마다 SDF actor들의 구성 순서를 찾아, ready configuration queue(ready CQ)에 저장한 후에, 전체 시스템의 state transition을 수행하며, 이 과정에서 FPGA에 (기존에 FPGA를 점유하고 있던 SDF actor의 종료 등으로 인해) 공간이 남으면, 실시간 구성스케줄러는 ready CQ를 살펴보고, 필요한 구성을 다운로드한다. 본 논문에서 제시한 실시간 구성 방법을 MPEG4의 natural video decoder와 IS95의 modem 예제에 적용해 본 결과, 수행 시간이 최대 21.8%까지 향상되었으며 메모리 사용의 부담은 무시할 수 있을 정도였다.

  • The purpose of this study was to compare the performance mode of housework related to daily meals. The data for 214 Korean couples living in Seoul and 136 Japanese Couples in Tokyo were collected using structured questionnaires and time diaries. The performance mode of housework were analyzed according to the employment status of wives. The results were as follows; Generally Koreans and Japanese wives had similar patterns in the time use of meals preparation and dish washing. In both nations Husbands seldom participated meals preparation, wives did most part of the work. But Japanese husbands of full-time employed wives spent more time on meals preparation than their Korean counterparts did. Korean wives received more help from other family members and paid labor, on the contrary Japanese wives purchased more ready-made goods for food preparation.

  • This article is an attempt to explain, at least in part, the contemporary Korean women's consciousness of Western Dreasses. As time changes, the role of clothing undergoes varisous transitions, while values and ways of life are constantly in change. It is, therefore, proper and appropriate to recognize as among the major aspects of social psychology such phenomenon as interests, understanding of clothing, the choice of a dress, and attitudes toward clothing, etc. The purpose of this study is to discover problems concerning and their clothing and their solutions, by means of a surveying approach. The method of research used is based upon questionares distributed to parents of first-year pupils in elementary schools and to female clerks working in offices, covering the period from August through October, 1976. The number of the questionares distrubuted totalled 600, and 526 were returned to the research to be utilized for analysis. The contents of the survey included such things as values concerning clothing, kinds of clothing and their practical use, the selection of clothing and the method of purchase, fashions, etc. The classification of aquisition are self-made clothing, clothing made to order and ready-made materials. It is composed of 25 items, including affirmative reasons as well as negative ones. The processing of the material returned was made by using the computer, and based upon classifications such as ages, monthly income, occupations; thus diagraming the result in percentages. The conclusion made and the improvements proposed are as follows: 1. The values of clothing were placed on the expression of the wearer's personality (32.7) and on eauty(28. 6%). The lower age group places is stress upon the expression of personality, while the higher age group stresses beauty. About 50% of wearers are contented with their clothing, their clothing, the rest of whom them indicating their dissatisfaction with what they wear. As to designs at the time of selection, about 46% indicated their preference of personal expression, 31.8% on usefulness. In selecting material, practicality is emphasized; in selecting patterns, single color is preferred. In short, personal expression and esthetic values are primary, with consideration of practicality in mind. 2. The classification of clothing according to their uses indicates the highest numbers in normal wear (home wears) and clothings to be worn outside home. As to evening dresses, (party dress) only one or two articles were checked by many, and no such article was clamed to be possessed by most. The highest ratio of wearing was shown in the case of home wear (47.3%) and clothing to be worn outside the home, which is 55.8%. The budget for one article of clothing was greatest in the case of home wear, and clothing worn outside the home. Many used both kinds of articles for the same purpose. It is desirable, therefore, that the kinds of clothing should be varied according to the purpose for which they are worn, and that clothing appropriate for that purpose should be worn. 3. The motivation for purchasing clothing was highly chosen in the item of seasonal change, which was 55.7%; Clothing deliberately made was indicated by 45.2%. In the mothods of purchasing clothing, clothing made to order and ready-made was indicated by 44.4%, which is the highest; Clothing made to order was 25.4%, and self-sewing was 1.1%, which is the lowest. (1) In the case of self-sewing, "I like it but it is very hard," was checked by 43.6%; "It is so difficult that I cannot wear such clothing" was checked by 13.3%. From these, we can conclude that the questionees are willing to make clothing by themselves, but techniques involved in sewing and at her problems involved in the skill are complicated but when those problems are eliminated there is a possibility for practice. The response checked by questionees concerning the self-sewing was, "It's economical", which is a clear indication that many questionees are positive for self-sewing. It is generally believed that ready-made clothing is cheaper, but it is not necessarily so. In consideration of the quality of clothing, self-sewing is a necessity, and it is desirable that it should be encouraged. (3) Problems involved in ready-made clothing, such as designs, skills, size (fitting) should be eliminated. When these problems are scientifically gotten rid of, it is possible that affirmative returns will be expected. Affirmative responses such as "Ready-made clothing is economical," "You can select there on the spot," are good signs that many women expect to wear ready-made clothing. It is in this sense that the prospect for ready-made clothing is brighter when much development for ready-made clothing is on the way. 4. Much concern for fashion are checked in such item of questions as "Fashionable clothing in the show window," "Clothes worn by women." The first item was checked by 50.1 %, and the second was checked by 48.6%. The reason for following fashion is "Because many people wear them," which was indicated by 30.4%. The reason for not following fashion is "It is too expensive," which was checked by 29.6%. The 26.2% of the answers indicated that "Fashionable clothing is devoid of personality," The influences of fashion over the development of fashion over the development of clothing are two-fold: Esthetic and active. It is not to be deniable that people follow fashion more or less. 1978.9>
