The administration of a regional public hospitals are expending from profit preference to publicity preference. The weight rate for a profitability and publicity of performance assessment has changed from 84:16 which was resulted by the assessment executed firstly in 1989 to 39:61 as resulted in 2004, the final assessment execution in 2005. Regional public hospitals are exerting and promoting a magnification in public sector to raise up the public-score. With comparison between publicity scores and profitability scores in original scores basis excluding weight rate, the publicity scores ranked higher than profitability scores although the latter was higher by 2002. However, for the administration performance of the regional public hospitals, the deficits increased 11 times from \92.6billion deficits with \460.3billion cost increased by 457% although income as \367.7billion increased by 394% comparing the last 2004 year to the first 1989 year for profit & loss statement of a regional public hospitals. There was analysis for the relation in yearly basis partitioning publicity and profitability for the assessment scores of the to regional public hospitals confirm the accumulated deficits of the hospitals like this attribute to the extension of public sector. The result showed that there was distinct plus relationship from 1999 although a minus relationship in general until 1997 except 1992 and there is a more plus relationship as approaching 2004. That is, it is hard to tell that the accumulated deficits increase of regional government medical center attributed to extension of public sector. On the contrary, the analysis showed the extension of public sector has a mutual relationship with uplift of profitability Meanwhile, it showed that operation cost rate and labor cost are the factors which influence a revenue & expenditure rate among the profitability index according to the results of relation analysis for the representative index of profitability and that of publicity.

The study was conducted to examine the possible psychological difference in visual preference for natural landscape depending on the residence characteristic of the visitors, with the aim to use as the reference when creating space for natural landscape. Visitors were classified into three groups, namely, urban, suburban, and rural residents, and their preferred type of landscape was surveyed. The result showed that regardless of their residence the highest preference was to the place with superior natural landscape features, and among such features the common preference was toward the landscapes with horizons and those with animals. Urban and suburban residents showed similar preference pattern, and there was artistically significant difference with rural residents. In this respect, the difference in preference for natural landscapes could be induced between urban and rural residents. Rural residents had similar preference with urban residents in that they both preferred the place with superior natural landscape features, but differed in that the former had significantly higher preference toward the landscapes that have mixed artificial elements. From the above research, the following conclusions can be inferred:for regions that need to create natural landscapes, differentiated visual landscape plans and strategies need to be established taking into account, inter alia, the natural richness of the neighborhood natural environment; for regions that need to conserve and manage natural environment and landscapes, the measures to adjust the natural landscape management plans need to be established taking into account the neighborhood environment of the protected areas and the number of visitors to the region.

This study analyzed the quality characteristics of nutritional bars with varying concentrations (0, 0.5, 1.5, 2.5%) of Enteromorpha intenstinalis powder added. To achieve this, color analysis, an assessment of DPPH radical scavenging activities, and sensory evaluations were performed. The results revealed that as the amount of Enteromorpha intestinalis powder (EIP) increased, pH and lightness values decreased. DPPH radical scavenging activities of 75.26%, 56.11%, 71.59%, and 62.49% were exhibited for the 0%, 0.5%, 1.5%, and 2.5% concentrations, respectively at 50 mg/mL. Significant differences were observed between the samples with respect to the color, appearance, texture, taste, and overall preference for the nutritional bars. Overall preference was highest for the nutritional bar with 1.5% Enteromorpha intenstinalis powder added. Therefore, adding 1.5% of Enteromorpha intenstinalis powder to a nutritional bar is most suitable for enhancing preference and quality characteristics.

This study aims to find out various users' diverse interior design needs for their housing and interior design through the personality, which is intrinsic and consistent traits of the individual. The survey research followed the literature reviews including personality studies and interior design assessments. 176 undergraduate and graduate students as controlled by age, sex, and major answered the questionnaire. Their housing and interior design attitudes, the semiotic assessment of interior design styles, and interior design preference were compared in accordance with four pairs of preference dichotomy of MBTI (Myers-Briggs Type Indicator): Extraversion -Introversion, Sensing-iNtuition, Thinking-Feeling, Judging-Perceiving. As a result, the framework of housing and interior design needs by the users' personality types are proposed. It shows specific needs for 16 types of personality based on eight preference dichotomy: extroversion-open, introversion-closed, sensing-functional, intuition-emotional, thinking-restricted, feeling-receptive, judging-simple, and perceiving-creative.

Engineering design can be viewed as a decision making process, which involves the nonlinear tradeoffs task among the multiple conflicting attributes and considers the robustness of design. In order to obtain best engineering design, methodology for accurate assessment of his/her preference about the multiple attributes is required. Conventionally, intuitive procedures based on lottery questions are used to elicit the designer's preference structure: however, they can lead to inconsistent and inexact preference results due to the rank reversal problems derived from the designer's big cognitive burden. In this paper, alternatively, a design methodology based on multiattribute utility function through the pairwise comparison among alternatives is presented. The proposed procedure is applied to an actual injection mold design with the aid of the CAE simulation and the result is discussed.

This study developed a vegetable preference increase program that can be applied at the Center for Children's Foodservice Management (CCFM) for children in child-care facilities and kindergarten and the training performance was evaluated by 192 5-year old children. Teachers considered 'disliked food' ($3.23{\pm}0.85/out$ of 5) as the most serious nutritional problem and typical disliked food was 'vegetables' (54.2%). Based on this finding, to increase the preference for vegetables, a five-phase education program was developed. In this program, each phase was composed of activities to increase children's interest in vegetables by using each sense out of the five senses. Center dieticians had visited and conducted the program in 12 facilities. By using an illustration assessment tool, the training performance was evaluated by comparing the children's knowledge level and their preference changes in vegetables. Consequently, as examined by 10 questions on the knowledge of vegetables, trained children's (in total 192) knowledge of vegetables had considerably increased (p<0.01, p<0.001), and their preference for 15 out of the 16 vegetables, except for carrots, also showed a considerable preference increase after the training (p<0.01, p<0.001). Therefore, this program is considered to have contributed to reducing disliked vegetable eating behaviors.

Environmental protection and precaution are the most frequently considered issues in the recent research fields for our present and future surroundings. However, it seems that these environmental issues were less reflected in local-level development plans, and caused several cases of environmental pollution, therefore it became a major concern of local governments and the communities. The role of a 'Local EIA(Environment Impact Assessment)' can be a core issue for the positive preferences of the local-level development plans. Cases of Local EIA in Germany which have been implied successfully are reviewed to generate a local EIA movement and to produce a guideline for Korean local governments. The local EIA in Germany was broadly commenced in the middle of 1980s, and a decade later it was carried out for over 200 of local governments. To produce a better suggestion for Korean local EIA, comparison and analysis of detail data of the German local EIA was carried out, and tested for fourteen cities in Korea based on five categories: i) assessment subject, ii) assessment procedure, iii) main office for assessment, iv) assessment factor and v) assessment standard. Prior suggestions for greater preference of local EIA in Korea are: it is necessary that I) launch of a support system in central government to help the movement of local government; Ⅱ) a knowledge-based expert group in local government which has by all means of exclusive responsibility far any action(new application or performance of local EIA) : 111) establishment of 'environmental protection measure' in local government level for environmental precaution based on individual environmental character and values in their communities.
