Six sigma is an innovative management movement which provides improved business process by adapting the paradigm and the trend of market and customers. Suitable selection of six sigma project could highly reduce the costs, improve the quality, and enhance the customer satisfaction. There are existing studies on the selection of Six Sigma projects, but few studies have been conducted to select the correct project under an incomplete information environment. The purpose of this study is to propose the application of integrated MCDM techniques for correct project selection under incomplete information. The project selection process of six sigma involves four steps as follows: 1) determination of project selection criteria 2) calculation of relative importance of team member's competencies 3) assessment with project preference scale 4) finalization of ranking the projects. This study proposes the combination methods by applying group fuzzy Analytical Hierarchy Process (AHP), an easy defuzzified number of Trapezoidal Fuzzy Number (TrFN) and Grey Relational Analysis (GRA). Both of the weight of project selection criteria and the relative importance of team member's competencies can be evaluated by group fuzzy AHP. Project preferences are assessed by easy defuzzified scale of TrFN in case of incomplete information.)

This study presents an analysis of bycatch data concerning Pacific white-sided dolphins (Lagenorhynchus obliquidens) along the Korean coast from 2016 to 2021. A total of 503 bycatches were examined, encompassing data on year, month, body length, sex, latitude (N), longitude (E), and fishing gear. Bycatch was the most frequent in waters with a longitude of less than 130°E, particularly in the southern coastal region at a latitude of 35.5°N, with a higher likelihood of bycatch in lower latitudes. Since 2017, a decreasing trend in bycatches has been observed. The sex distribution of bycaught dolphins showed a predominance of males (40%), followed by females (31%), with an unclassified category at 29%, though no statistically significant differences were found (p > 0.05). Seasonal analysis indicated that bycatch predominantly occurred during the winter months, with significant monthly variations (p < 0.01). Pacific white-sided dolphins were primarily ensnared in gill nets and, to a lesser extent, in stationary nets. Statistical analysis by gear type revealed a significant preference for gill nets (p < 0.001). Considering body length composition in relation to latitude, it is suggested that Pacific white-sided dolphins may utilize the southern waters of the East Sea as a potential nursery ground, though this was not confirmed at a significant level, emphasizing the need for further in-depth monitoring and ecological investigations. Given that there are approximately 27 different types of gill nets associated with the majority of bycatches, more detailed research is warranted to divide these gear types into finer subcategories for estimating bycatch relationships, ultimately leading to the development of effective conservation and management strategies.

Noting that there is an increasing trend of the so-called 'neo-single life style' among women these days, this research aims to make a product development for these neo-single women in this era of families of a single member by analyzing their concepts and characteristics. We payed a particular attention to the data from such sources as newspapers, magazines or the articles in the Internet. The essence of our research lies in the analysis of target market, in the suggestions in the brand planning and product development and in the designs of fashion and interior products for them. The result of this research is as follows. First, it turns out that these neo-single women enjoy a kind of multi-mixing code lifestyle rather than showing a preference for a particular brand. For this reason, we have decided to pursue a multi-concept brand fonn as a right direction for brand planning for them. Second, as for a philosophy behind the brands, we suggest a concept of 'small utopia' for neo-single women and express such as new aristocracy, happiness and pleasure. Third, we adopt 'YOU' as the name of the brand as it reflects their various life styles and characteristics. Fourth, as for the product development of F/W in 2007, we have decided on 'Minimal Natural' as it mixes up the concepts of the controlled beauty of sophistication and multi-functional elements and 'Modern Primitive' as it expresses the ethnic elements on modern images having craft factors and modern images. We have performed concrete tasks in creating images, coloring, making fabrics for each theme. Fifth, we have chosen and suggested other products that are suitable for these neo-single women who seek for multi-functional but simple kinds after surveying a wide range of products in magazines or in the Internet.

This study investigated the proximate composition, sweetness, color, texture, and sensory properties of baked Gangjung prepared using different coating syrups (maltose syrup, oligosaccharide, rice syrup, and maltitol syrup). The crude protein content was 3.22~3.28% in baked Gangjung prepared with maltose syrup, oligosaccharide, or rice syrup, while that prepared using maltitol syrup had 2.61%. Crude ash was the highest when rice syrup was used (1.08%), and the lowest when maltose syrup or oligosaccharide was used (0.64% and 0.68%, respectively). The sweetness of the baked Gangjung was the highest in the rice syrup group, at $70.07^{\circ}Brix$, and lowest in the maltose syrup group, at $33.5^{\circ}Brix$ (p<0.05). The hardness of the Gangjung prepared with the different coating syrups was the highest for the grain syrup (1.42), followed by the oligosaccharide group at 0.96, maltose syrup (0.40), and maltitol syrup (0.35) (p<0.05). The number of peaks and the indirect measure of crispness also showed the highest values for the rice syrup group (p<0.05), but there was no significant difference among the values in the other groups. Lightness was in the range of 63.26~73.04 depending on the coating syrup, decreasing from the oligosaccharide to the maltitol, rice syrup, and then to the maltose syrup group (p<0.05). The a-value was the highest for the maltose and rice syrup groups at 10.69 and 10.38, respectively (p<0.05), and the b-value showed the same trend. Baked Gangjung showed the highest scores for color, flavor, and overall preference when prepared using maltitol syrup.

Fashion icons of 21st century are not only the fashion leaders that show fashion trend but also the typical fashion signs or symbols that show visually changes in sensibility trends. The purpose of this study was to analyze the framework of 21st century fashion by the public to recognize through these changes. In this study, the background of the occurrence of various 21st century fashion icons and their characteristics were investigated and the changes of revealed features and symbolic meanings were examined compared with them of 20th century. The 24 celebrities which have been called as the bests of fashion icons since year 2000 were selected by searching the most popular search engines such as daum, yahoo and google, and 13 of them were picked as the highest in preference and awareness by surveying 50 students majoring in fashion. And then their fashion styles, backgrounds, and influence on the public fashion were studied. As a result, the 21st century fashion icons reflecting the cultural characteristics such as convergence and exaggeration and the sensitivities of fusion, collaboration, hybrid sensibility in art were powerful enough to create innovative styles destroying the era and the standard. Their styles have constantly created new looks. The exposed new individual sensitivities on media-fusion of two or more sensibility and coordination techniques without being tied to the existing anchorage system-were as influential as high fashion and leaded the imitation and reproduction by dazzling the public. As the media become more powerful, the influence of fashion icons interacted more closely with the public and has been evolved through the sensitivity of the reversal, cultural, economic, visual, or temporal fusions. To sum up, it is shown that the outstanding fashion styles suggested by the leading fashion designers have approach to the public more closely by the fashion icons.

The purpose of this study is to provide the fundamental data needed in analyzing customer needs and understanding products in developing designs, to help designers to have better understanding of digital camera products, and to support the setting of concepts in developing designs, by understanding the specific properties of products that have specific purposes. In this study, homogeneity analysis was performed to the collected products launched from 2000 until now and representative products were selected to extract the questions on the adjectives and preferences felt form such products. Based on the questions, basic questionnaire survey and subject image analysis was performed in relation to the elements of images preferred by customers through the regression analysis of dependent variables and preferences and the regression analysis of purchasing power. When we design for digital camera, we must consider about the elements of digital cameras and the terms convenient, sensitive, functional, and grace. In terms of whole trend of shape, the shape highlighting grips and the digital cameras having grips, large LCD, dark colors, and manual buttons were preferred.

There are lots of tries to make a combination between the technology development which is fast arisen and cultural phenomenon which imply in it. We called this research area as the cultural computing or cultural modeling. In this paper, we examine the cultural user interface design, especially cultural design structure based on the contents considering the research trend of the cultural modeling. To design of the contents based on the culture, there is a need to draw a structure of the cultural feature for the contents. To do this, we combine Hofstede's cultural dimensions model with the data of contents and then we suggest cultural index of content(CiCo). Furthermore, we draw national index of cultural content(NiCC), through conjoining CiCo with preference pattern of content consumption for the nations. Suggested CiCo and NiCC are based on Hofstede's model, however they are improved approximately 10% of the explanatory of model than the Hofstede's.

This study conducted a survey and investigated students' opinions and design preferences to physical education (PE) uniforms for elementary, middle and high school students using PE uniforms for the following purposes: to increase satisfaction with PE uniforms; present basic data for the development of PE uniforms helping to improve the quality of school life; and propose the development direction of PE uniforms. PE uniforms shall be developed with the components of uniforms, symbolism, functionality and aesthetics. The symbolism of PE uniforms expresses the affiliations of people wearing them and makes them have a sense of affiliation. The functionality presents convenience in students' physical activities and intramural/extracurricular activities. The aesthetics reflects the aesthetically sophisticated sport wear trend in PE uniforms. The development direction of PE uniforms was organized based on the result of analyzing and investigating students' opinions and design preferences to PE uniforms. There were differences in students' opinions and preferences to PE uniforms according to the type of student groups (elementary, middle and high school). In addition, there were clear gender-differences in the same student group. An effort might be required to reflect students' preferences because PE uniforms which students had currently worn at school had been manufactured without the reflection of students' opinions.

The purpose of this study was to identify factors of shopping orientation and factors of preferred stores for female shoppers aged from 45 to 64. Also women's markets for these ages were segmented based on their shopping orientation, and consumer groups were compared in terms of demographics and preferred store characteristics. Data from 238 women aged between 45-64 were collected by survey method and used for statistical analyses. Factor analysis, cluster analysis, $X^2$ test, F test, Duncan test were done. The results were as follows. First, five shopping orientation factors, such as high involvement, fashion orientation, brand orientation, other people orientation, and economic orientation were found. Second, five factors of preferred store characteristics were identified. They were store environment, product characteristics, trend and brand, accessibility, and sales personnel factors. Four consumer groups of brand pursuing, fashion pursuing, other-dependent, and high-involvement were classified. Those consumer groups showed significant differences in terms of demographics and preferred store characteristics. In conclusion, Korean women aged 45-64 were shown to have some differences in their shopping orientation compared with young women and to differ in preferred store factors among their groups.

Purpose: The objective of this study was to publicly report the hospital-level surgical volume for 7 types of surgery including gastrectomy. Also, to investigate the changes in patient behaviors after the public reporting among patients with gastrectomy. Methods: This study used data from the National Health Insurance Service Cohort. The data comprised of 2,214 patients who were diagnosed with gastric cancer and underwent gastrectomy during 2004-2012. An interrupted time series analysis was performed to investigate the association between patients' choice and public reporting. Results: 79.27% of the patients visited a hospital with high surgical volume. The time trend after introduction of public reporting was positively associated with visiting a high volume hospital (per 1 month, RR: 1.004, p=0.0329). However, after adjusting the health policies by reducing copayment, public reporting on surgical volume was not associated with visiting a high volume hospital. Sub-group analyses had also similar results. Conclusion: Patients were more affected by policies on economic support than on public reporting, and the changes in treatment options may have been affected by the increasing preference for large size hospitals. Thus, public reporting did not significantly improve the options available for patients and their decision making on health care utilization.
