  • This study aims to analyze the evaluation of the residential environment on the permanent rental housing in Busan. The Permanent Rental Housing policy is one of the special measures which contribute to getting the low-income urban dwellers settled in places of their own. Unfortunately the government has focused on expanding the quantity of housing even though housing doesn't mean just a physical object but the foundation of life. So the occupants who answered the survey lived in the permanent rental housing which were constructed by Busan Metropolitan Corporation. The purpose of the study is to give suggestions which can make up for dissatisfaction and apply preference of occupants based on the results of the research. The result of this study is in following; there were few significant managerial variables determinants of residential satisfaction. And significant variables are; position of rooms and bathroom facilities in internal building characteristics, color of apartment and playground in exterior building characteristics, commuting distance and viewshaft in locational characteristics. Therefore, the government needs to use cutting edge housing technologies aimed at improvement of residential environment and achievement of affordable expense simultaneously.

  • This study was conducted to investigate rheological and sensory characteristics of fish paste prepared with Curcuma longa L. powder (0, 1, 3, 5, 7%). The moisture content of the fish paste ranged from 71.35 to 72.97%. Increasing the amount of Curcuma longa L. powder in the fish paste tended to decrease the pH value and the folding test good score in all samples. Increasing the amount of Curcuma longa L. powder in the fish paste also tended to decrease the lightness (L) in the hunter color value, but to increase the redness (a) and yellowness (b). For the textural characteristics, the addition of Curcuma longa L. powder increased the strength and decreased the springiness. In a sensory evaluation, the addition of 3% Curcuma longa L. powder had the best score in taste and overall preference. Therefore, this results suggest that adding 3% Curcuma longa L. powder would be feasible for making Curcuma longa L. fish paste.

  • The objective of this study was to determine the effects of wine and different meat bones added in brown sauce. Sensory evaluation of brown sauce showed that brown stock and brown sauce made by adding wine and replacing some of veal bones with chicken bones were preferred most, and the brown sauce made by brown stock and burre manie in the ratio of 12:1 was preferred most. Sensory properties of palatability. flavor and gloss were positively correlated with the overall preference. The brown sauce made with wine and some of chicken bones had 77.60% of water content and 1.79% of lipid content, which was the lowest, but its protein content was similar to the others. Whereas the brown sauce made with wine and some of chicken bones gave the darkest color, the one made with some of pork bones and without wine showed the lightest color. The viscosity was the highest in the sauce made with some of chicken bones and without wine. The sauce made with wine showed lower viscosity than the one without wine.

  • To stabilize the supply of kimchi by extending the storage period of spring kimchi cabbage, this study manufactured kimchi from spring kimchi cabbage under varying storage conditions and periods, and analyzed their quality and sensory characteristics following the maturing period. Trimming loss was lowest in the group of plasma+reverse direction+predrying+HDPE film processing. The salting yield of spring kimchi cabbage stored for 12 weeks was lower than that of spring kimchi cabbage stored for 6 weeks, and the kimchi yield was low in the pre-treatment group of spring kimchi cabbage stored for 12 weeks. The firmness was slightly different according to the storage period from one month of maturation. From the perspective of pH and acidity, the maturation in the reverse direction+pre-drying+HDPE film processing group was slower than that in the normal group (<0.05). In the sensory evaluation, the preference was increased in the low temperature storage processing group as the maturation period was increased (<0.05).

  • The objective of this study is to evaluate the quality characteristics of turmeric powder Dasik, a Korean traditional cookie, prepared by different additions of turmeric powder(0%, 1%, 2%, 3%, 4%). The result of the study is as follows. As the level of turmeric powder in the formulation increased, the moisture contents of the samples increased. As the content of the turmeric powder increased, the L-values of the turmeric powder Dasik significantly decreased, and the a- and b-values also significantly increased. Also, the hardness, gumminess, springiness, cohesiveness and chewiness of the turmeric powder Dasik increased, whereas its adhesiveness decreased as the amount of turmeric powder increased. The sensory evaluation results showed that the 2% turmeric powder sample showed the highest preference scores; therefore, the 2% turmeric powder Dasik prepared with 98g of flour, 2g of turmeric powder, and 80g of honey was chosen as the most preferred product. It is expected that the development of Dasik added with functional food such as turmeric powder can influence the use of turmeric and increase the consumption of Korean traditional cookies.

  • The properties of non-waxy rice, Dongjin 1, cultivated with conventional farming (CF) and environmentally-harmonized farming (EHF) using hairy vetch were compared to determine rice water absorption, physicochemical and pasting properties, antioxidant activities of brown and white rice, and a sensory evaluation of cooked white rice was carried out. EHF was treated with green manure crops such as hairy vetch and chitinase, which produce microorganism culture solution. CF was applied with seed disinfection treatments, fertilizer herbicides, and agricultural chemicals for the control of pests and diseases. The absorption level of EHF rice was higher than that of CF rice grain, regardless of the cultivation methods used. The ash and crude lipid contents were higher, but protein and dietary fiber contents were lower in the CF rice than in the EHF rice. The total starch content, water binding capacity, and swelling power of white rice were higher than those of brown rice, regardless of the cultivation methods used. The DPPH's antioxidant activity was shown as follows: EHF brown rice, EHF white rice and CF rice, in a decreasing order. The initial pasting temperature of EHF rice was lower than that of CF rice, but the peak, cold, and breakdown viscosities exhibited reverse trends. The sensory evaluation showed that the cooked white rice cultivated with EHF was not significantly different from that cultivated with CF (p<0.05). The overall preference of cooked rice did not show significant differences between the two cultivation methods (p<0.05).

  • We sought to develop lotus (Nelumbo nucifera) root Jeonggwa as a health food. Jeonggwa was mixed with 0-8% (w/w) Omija water extract and stored at $25^{\circ}C$ for 12 weeks. Quality characteristics during storage were investigated. The pH of Jeonggwa fell, and the acidity level rose, as increasing amounts of Omija water extract were added. The moisture content of Jeonggwa rose from 7-8% to 14-17% within 2 weeks of storage at $25^{\circ}C$, and was maintained at that level to the end of storage. Total viable bacterial cells in Jeonggwa were initially 2.4~3.2 log CFU/g, and increased in number during storage, but never exceeded 4 log CFU/g. The shelf life of Jeonggwa was extended when Omija extract was added. The lightness (L), redness (a). and yellowness (b) of Jeonggwa during storage at $25^{\circ}C$ were highest in control samples and the values fell with increasing Omija extract concentration (p<0.001). Mechanical evaluation Jeonggwa showed that various tested parameters fell during storage at $25^{\circ}C$. The hardness and strength of Jeonggwa were significantly reduced as the Omija extract concentration rose (p<0.05). In sensory evaluation tests, the acceptability of Jeonggwa was optimal when 2~4% (w/w) Omija extract was added.

  • Most of the important visual information is presented to driver through the display panel that is related to the vehicle. If display panel is designed with the c consideration of driver's visibility, drivers can get broad visual field and visual I information related to vehicle promptly and exactly during driving situation. Therefore display panel has direct relationship with the driver's task performance and it can be considered as an important device that affects the driver-automotive interaction. Many r researches about shape, characteristic and color of display panel have been performed, but not sufficient in this country Nowadays most of vehicles has an analog type display. but its shape and arrangement a are various without any definite standards about position. Therefore. experiments using evaluation tool (VISVEC System) were conducted to inquire the driver's preference on the major objects arrangement of display panel (speedometer. tachometer. fuel meter. and t thermometer) and to ascertain the factors that have an effect on drivers according to the objects position of the display panel The experiment results showed that there was no correlation between the arrangement c characteristics preferred by subjects and the cognitive accuracy but the cognition of V visual information more easy when the each major object has its area.

  • The aim of this paper is to extend the TOPSIS(Technique for Order Preference by Similarity to Ideal Solution) to the fuzzy environment for solving the disaster recovery priority decision problem in credit bureau business information system. In this paper, the rating of each information systems and the weight of each criterion are described by linguistic terms which can be expressed in trapezoidal fuzzy numbers. Then, a vertex method is proposed to calculate the distance between two trapezoidal fuzzy numbers. According to the concept of the TOPSIS, a closeness coefficient is defined to determine the ranking order of all information systems. The combination between the fuzzy set and TOPSIS brings several benefits when compared with other approaches, such that the fuzzy TOPSIS require few fuzzy judgements to parameterization, which contributes to the agility of the decision process, it does not limit the number of alternatives simultaneously evaluated, and it does not cause the ranking reversal problem when a new alternative is included in the evaluation process. This paper is demonstrated with a real case study of a credit rating agency involving 9 evaluation criteria and 9 credit bureau business information systems assessed by 6 evaluators, and provide the systematic disaster recovery framework for BCP(Business Continuity Planning) to practitioner. Finally, this paper show that the procedure of the proposed fuzzy TOPSIS method is well suited as a decision-making tool for the disaster recovery priority decision problem in credit bureau business information system.
