In structural design, the design variables are frequently selected from certain discrete values. Various optimization algorithms have been developed fDr discrete design. It is well known that many function evaluations are needed in such optimization. Recently, sequential algorithm with orthogonal arrays (SOA), which is a search algorithm for a local minimum in a discrete space, has been developed. It considerably reduces the number of function evaluations. However, it only finds a local minimum and the final solution depends on the initial values of the design variables. A new algorithm is proposed to adopt a genetic algorithm (GA) in SOA. The GA can find a solution in a global sense. The solution from the GA is used as the initial design of SOA. A sequential usage of the GA and SOA is carried out in an iterative manner until the convergence criteria are satisfied. The performance of the algorithm is evaluated by various examples.

The aim of this study was to investigate the effects of adding different amounts (0, 4, 8, 12, 16%) of green laver powder to Sulgidduk, a traditional Korean rice cake product, in terms of textural properties and sensory characteristics. During storage, moisture content was reduced less in the green laver-added samples as compared to the control group. With increasing additions of green laver powder, L-values decreased, a-values increased significantly, and b-values decreased; however, no changes were observed in the control group. In the mechanical evaluations, hardness increased less during storage in the green laver added samples than in the control group. Adhesiveness did not differ significantly by the addition of green laver powder. Springiness, cohesiveness, gumminess, and chewiness showed significant differences, and increased or decreased repeatedly during storage. In the sensory evaluations, the 16% green laver group received the highest scores for color, flavor, and taste Moistness and softness were evaluated higher in the green laver groups as compared to the control group; however, moistness, softness, and elasticity did not differ significantly during storage.

This research investigated consumer's usage of, evaluation on and satisfaction of the Auction Site, with a view to analyze the key factors influencing a commission paid Auction Site. The findings of results from the analysis are summarized as follows. First of all, the consumer group at the age equal to and less than 20 years old showed the highest purchasing frequency, and the consumer group with a household income less than 2,500,000 won showed the highest number of hours on the site. Secondly, the evaluation index showed that consumers think highly of the complaint resolution process, and, especially, the aged consumer group respected the Auction Site's level of confidentiality of transaction and privacy. Thirdly, among consumers' satisfaction, subdivided by types, price satisfaction was the highest followed by quality satisfaction, settlement satisfaction, delivery satisfaction, information satisfaction and AS satisfaction, in that order. Fourthly, in the event consumers used the commission paid Auction Site, the number of times it has been used, evaluations related to information provision and evaluations on confidentiality of transactions and privacy are influential parameters.

The recent successes of systems like Google, Wikipedia and InnoCentive suggest that the time is now ripe for more such systems. Thus, we want to explore these systems and exploit them from a viewpoint of social psychology prior to technological progress. First of all, we examine the difference between 'wisdom of crowds' and 'crowd psychology'. There are two classes, which are for senior management major students. Conditions of two are same, except a class time. Forty five students in one class are tested for this experiment. They form a group with five people and are divided into 9 groups. In a case of a morning class, peer-to-peer evaluations are given to individuals in a class when a group presentation for a final project is given. On the other hand, in a case of afternoon class, peer-to-peer evaluations are given to each group in a class. The result is quite fruitful. The first is that an expert's evaluation for a project agrees with students, who are beginners in this field in the degree of more than 95%. However, in the case of afternoon class, students' group evaluation turns out to agree with an expert's one less than 53%. Morning class experiment result proves the truth of collective intelligence again. It tunrs out independent and confidential opinions are more cost effective and give right answers to questions than group opinions.

This study analyzed middle-aged woman volunteers' evaluations on their volunteering and its implications for the adult life-long education. The subjects were 126 women aged from 35 to 59 who enrolled in the volunteer centers in Busan, Korea. They participated in the survey of the volunteer effects and the factors that made them continue to volunteer. Survey said, middle-aged women volunteers perceived that they got positive feedback from others and themselves and it made them keep doing on volunteering. Based on their volunteering experiences, they reported the personal effects such as positivism, caring, volunteering capacity, industry, maturity and the family member's effects such as positivism and participating in their volunteering. They also mentioned that they had positive and negative effects on family relationship such as family relation reinforcement and being indifferent to their own family. Based on the research findings, it was the emphasized that supports for volunteering of the middle-aged women that helps them to accomplish the developmental tasks in the middle age are necessary. A scheme of linkage between volunteering and the adult life-long education was also dealt with. Finally, the implications on the further studies in the field were discussed.

This study was carried out to evaluate the sensory evaluation of the muffins with mulberry leaf powder as well as their chemical characteristics. The muffins were prepared by adding 0%, 1 %, 2% and 3% mulberry leaf powder to the recipe. As a result of the sensory evaluations, the color, flavor and texture of the muffins of 2% mulberry leaf powder were found to be much better than those of the other groups. In the chemical composition analysis, increasing the mulberry leaf powder led to a significant increase in the content of crude protein, moisture and crude ash, while crude fat was significantly decreased. As the ratio of mulberry leaf powder increased, Ca, Mg, Fe and Zn in the muffins increased proportionally (p<0.05). The lightness value, the redness value and the yellowness value decreased with the increase of mulberry leaves powder content. In a texture analyser test, hardness and cohesiveness decreased as the ratio of mulberry leaf powder increased. The adhesiveness of the muffins with 2% mulberry leaf powder was the strongest of all.

The purpose of the study was to perform research a proximate analyses and sensory evaluations for sulgidduk over a storage period, where the sulgidduk contained added with buchu powder added at 1%, 2%, and 3% concentrations. The general composition of the buchu powder was 34% crude protein, 1.8% crude lipid, and 21.8% crude fiber while the moisture contents of the buchu powder was 2.71%. The moisture contents of the sulgidduk samples over the storage period ranged from 34% to 38%. Color and moisture changes were not significant (p<0.05) during storage, while the values showed significant decreasing trends (p<0.05) with greater additions of buchu powder. In terms of textural characteristics, hardness, cohesiveness, gumminess, and chewiness decreased significantly (p<0.05) with greater concentrations of buchu power, while adhesiveness and springiness showed no significant differences(p<0.05). Based on the sensory evaluations, overall preference was high for the 3% buchu powder sample. This sample received high scores on flavor, color, taste, chewniess, and moisture, suggesting that adding 3% buchu powder would be feasible for making sulgidduk.

For fit satisfaction evaluation, the subjects were asked to put on the jackets from the seven manufacturers in random order, view how the jackets fit in a full-body mirror and answer questions regarding fitting in 22 specific areas, including the neck, shoulders, waist, hips and arms, as well as eight questions related to maneuverability. The surveys and evaluations were conducted between October 2007 and November 2008, and the compiled data were analyzed using the SPSS 14.0 statistics program. The One-way analysis of variance was performed to comparatively analyze the differences among the products from the seven manufacturers. Post-hoc tests were performed based on Duncan's test for the criteria that displayed significant differences. The results were summarized as follows. Fit evaluations were performed for the size 88 formal jackets from the seven manufacturers. All items, except the center front line, displayed significant differences at p<0.05 or higher among the manufacturers. The age group 20-39 felt that the main problems were in the shoulder, armscye, upper arm, waist, abdomen and hip areas. Modifying the shoulder area, armscye depth and hip areas severely compromises the jacket's balance, and attention to these areas must be given developed pattern design.
