This study examined salty taste acuity and salty taste preference and sodium intake in relation to zinc nutritional status in 2 rural populations in Korea. And we also examined the main food contributors of their sodium intakes. We enrolled 218 adults (66 men and 152 women) from the Kangneung and Samcheok regions in Korea's Kangwon province in our study conducted from December 2011 to February 2012. Participants from each region were divided into 3 groups based on their serum zinc level (T1: lowest, T2: intermediate, T3: highest). We compared the salty taste acuity and preference, Na index (Dish Frequency Questionnaire for estimation of habitual sodium intake), blood pressure, and intakes of nutrients including sodium by 3 groups of serum zinc level. The results were as follows: a higher serum zinc level indicated a lower sodium intake and Na index (P<0.05). The salty taste acuity was considerably higher for participants from the Kangneung region than those from the Samcheok region (P<0.05). And the serum zinc level was significantly higher in participants from the Kangneung region than those from the Samcheok region (P<0.05). We further divided the participants into 2 groups: those who consumed more zinc than the recommended intake (RI) and the others. We compared salty taste acuity and salty taste preference in the 2 groups. The salty taste threshold and palatable salty taste concentrations were lower for the group with a zinc intake above RI than for the group with zinc intake below the RI. However, the difference was not significant. This study confirms that taste function differs depending on zinc nutritional status. In future, it is required to a large-scale, long-term, prospective study on the correlation between zinc intake, serum zinc levels, and taste perception function and blood pressure.

The work-man's uniform should be coincident wit the image of his firm and accounted of the function according as its purpose. We made questions to 404 workers at 8 firm in our country through the questionnaire papers to know about a work-man's uniform and researched whether the satisfactory in wearing his uniform had relation with his type of business, grade, carrier, age, marriage, and monthly income. The results of this study is as follows; 1. In the uniform status of the fir, thee were many jumper styles in he design of the uniform. The color of that was more dark than bright and the materials of one was used much more chemical fiber than natural fiber. Each of the field office supplied the uniform to his work-man more frequently than the main office. All of firm payed off the uniform expense and decision of the uniform design was almost made both the firm and the labour union. 2. In he satisfaction of the uniform, the satisfaction of uniform was shown high in the design, color, materials, size and function. The highest dissatisfaction reason is as follows; it was disagreeable to concrete design in the design and dark color and keeping warm or draft was bad in the materials, the bust and pant's length was long in the size. 3. In preference of the uniform, the older of preference in the design was what the working environment and the image of firm was suitable, the characteristic uniform. The order of preference in the color was beige, blue, grey. The preference of in the materials was good to keep warm and draft. The preference in the pattern was 'no pattern' every type of business. The experts, or administrators and office workers than others preferred 'no pattern' of the uniform in the pattern.

본 연구는 다기준의사결정문제인 건설 프로젝트의 공법선정문제에 있어서 퍼지계층분석법 및 그 결과 생성되는 각 공법별 퍼지 점수의 상대평가를 위해 퍼지 선호도 함수를 적용하여 상대평가를 하고자 하였다. 지금까지의 건설 공법 선정에 대한 퍼지계층분석법에 대한 연구는 대부분 최종적인 공법선정을 위해서 각 공법별로 도출된 퍼지 점수의 순위결정기법으로 절대평가를 수행하였다. 그러나 이러한 기법은 비교 대상공법에 대한 일관적인 순위결과를 산출해 내지 못하므로 결과적으로 공법선정과정의 전반적인 타당성을 저해하는 문제점을 지니고 있었다. 따라서 본 연구에서는 건설 분야의 MCDM(Multiple Criteria Decision Making)에 관한 기존의 연구들을 바탕으로 순위 결정기법에 R.P.R(Relative Preference Ratio)기법을 도입하여 각 공법에 대한 퍼지 점수를 상대 평가함으로써 체계적이고 효율적인 건설 공법선정기법을 제시하였고, 이를 창호공법의 선정문제에 적용하여 그 타당성을 살펴보았다.

SIP(Session Initiation Protocol)에서의 Caller Preference는 송신자가 서버 측에서 자신의 요구를 처리하는데 관련된 각종 선호 사항들을 표현할 수 있도록 하고 또 수신자의 수신능력(Callee Capabilities)에 따라 적절한 호 처리를 진행할 수 있도록 하여주는 유용한 기능이다. 그러나 기존의 Preference 기능에서는 수신 대상을 선정함에 있어 미디어종류에 대한 일치 여부만을 고려하므로 호 설정 과정에서 상호간의 미디어 스트림에 대한 코덱과 같은 미디어 정보가 다를 경우 이를 재 협약하기 위한 추가적인 세션 협약 과정이 발생하게 된다. 따라서 본 논문에서는 이러한 문제점을 해결하기 위한 새로운 확장된 Caller Preference 기능을 제안하였다. 여기서는 SIP 기반의 VoIP(Voice over IP)시스템에서 네트워크 서버가 SIP 호를 연결할 수신대상을 결정하는데 있어서 세션에서의 미디어 스트림에 사용되는 세부적인 미디어 정보의 일치 여부를 판단하여 호 연결 후보 대상들 가운데 미디어 재 협약이 필요치 않은 대상에 우선권을 부여하여 효율적인 호 설정이 가능하도록 하였다.

The purpose of this study was to obtain and offer useful information on innerwear industry through an analysis of consumer purchasing behavior and preference of their between the 20's and 60's. From 310 questionnaires that were distributed, 308 with usable data were coded for further statistical analysis including descriptive statistics(frequency and chi-square test), by using SPSSWIN 10.0. The results were as follows.: It was found that the innerwear for men in their 20's should be developed in an attempt to place greater emphasis on improving functions as an outwear such as impact absorption and protection articulation required for outdoor activities such 3s mountain climbing and in-line skating, rather than the function of thermal insulation. In addition, the development of new materials that improves the hygroscopicity and rapid dryness is needed. For men in their 30's and 40's, the results suggest that innerwear should be designed as thinly as possible without compromising the silhouette of the outwear. For those in their 50's and 60's, it is recommended to intensify the aspects of health and hygiene of the innerwear, while maintaining the function of thermal insulation. Given that a large number of women purchase men's innerwear for their partners, it is important to strengthen the designs and marketing strategy specifically tailored to women's purchasing power.

Considering increasing demand for improved waist protectors for the elderly, in this study we sought to design a waist protector that reflects the body characteristics, preferences, and satisfactions of the elderly. A survey conducted to investigate elderly satisfaction with existing waist protectors, as well as their preferences in product function, design, and characteristics, found that consumers are not satisfied with current waist protector offerings and would prefer protectors that allow greater freedom to perform physical activities and that are more easily accessible. Based on the survey, we developed a guideline on function, design, and characteristics, resulting in four new waist protector designs: A and B for men, and C and D for women. Significant preference differences according to gender were reflected in the designs. For example, designs for female waist protectors focused much more on improving tightness, size, freedom of movement, and easy attachment or detachment than designs for male waist protectors did. Evaluation of satisfaction with new designs suggests that new designs meet the satisfaction criteria of elderly consumers, who express willingness to purchase and use them.

Recently the function of a department store has changed to the concept of a multi-functional center because of the alternative stores such as discount stores, home shopping, and internet shopping. This means that the front plaza of a department store is not a personal or private space any more, but a public space. This study focuses on the special character of public space through the classification and preference types of department store front plazas. The major results of this study can be summarized as follows: (1) Components of front plaza of department store are classified by three factors. The first factor, named "space limit", has 14 elements ; the second, named "space decoration" has 16 elements ; third, named "activity", has 2 elements. The first preferred element is easily- used and easily- serviced wide space. The second preferred element is the equipment that is placed linearly along the street. The third preferred element is cultural events. (2) The comparison between the frequency and preference shows that the plazas could not satisfy the user-needs. (3) Preference factors of front plazas were examined to three characters such as familiarity, peculiarity, and openness. Familiarity, peculiarity, openness have a positive correlation in all types. Peculiarity especially influences the other two space - preference factors.

Purpose: In this study consumers' preference for housing for elderly people was analyzed as well as the recognition by elders of silver town facilities, and their preference for service provided by silver town. The study was done to provide basic data for the development of silver town facilities that are low in cost and high in efficiency. Methods: A sample research was used in this study to analyze the understanding of old age, silver town, and service preference. Results: First, interest and intention to live in silver town was very positive, however low cost was also preferred and that is quite different to current silver towns of Korea. Second, women have more understanding of, requests for, and intention to move into silver town facilities than men. Women's demands for silver town facilities must be reflected in the development strategy of silver towns. Third, the most important part of activating silver town facilities is price strategy. Government political support is required in order to keep silver town move-in costs affordable. Fourth, silver towns must function as total service complex towns. Conclusion: This study is meaningful as efficient operation of silver town is suggested rather than facility degradation to achieve price reduction. This result is important to the development of silver towns based on consumer preference, as it suggests a development direction that is focused on securing differentiated services and programs.

In this paper we deal with the logistics brokerage process in which a logistics agent intermediates between vehicle owners and shippers for matching empty vehicles and freights. Based on the Multi-Criteria Decision Making (MCDM) methodology, the proposed agent system matches the most preferred empty vehicle to the shipper and the most preferred freight to the vehicle owner. In the proposed agent system, an MCDM based sensitivity analysis is also used for supporting decision makers under negotiations. Among various MCDM methodologies, Analytic Hierarchy Process (AHP) is utilized in this paper. Although AHP is one of the most popular MCDM methodologies, AHP needs a number of pair-wise comparisons for assessing alternatives and hence may give excessive decision making burden to the decision makers. In this paper, in order to reduce the decision making burden, a preference function based estimation method is proposed. We can expect that the MCDM based logistics brokerage agent can be used as an efficient and effective tool for e-logistics marketplaces on the internet.
