In product manufacturing industries, a recent issue is the green concept. The green concept is a complicated area. If the green concept is for products, its serious issues have to be criticized. Although the importance of the green concept has overflowed, its influences have not been disputed vigorously. So this study is to critic the serious issues of the green concept in aesthetics in product design, manufacturing, and products' prices. The green environment has four representative elements: systems, policies, minds, and technologies, but they are not in the field of design. An element of the green concept, green design is also a sub concept for design, so it should be based on aesthetics. It is green aesthetics. But since green design first appeared, it has never approached by aesthetics because it has mostly had social meanings and expectations. So for green aesthetics, to think about what makes a product, and what can be aesthetic issues among them are important. Products consist of form, structure, material, and technology. Form means different shapes in a structure, but there cannot be any specific directions for a green concept. Structure has two kinds: interior and exterior structure. While interior structure has a technological character, exterior structure is deeply related with aesthetics, but it has also no chance for green concept. Material can be divided as two also: aesthetic and technological. Aesthetics materials mean the colors, opacity, and tactile sense of materials, but they are not aesthetic issues. Technological materials are recycled materials or non-recycled materials. Even if recycled materials are used today, they are close to systems or policies rather than aesthetics. With this result, green aesthetics is a very difficult concept. Second, green products are usually 30% more expensive than general products. But every consumer has his or her own economical conditions, and nobody can coerce consumers into buying expensive green products for green environments. And green products without good quality cannot satisfy consumers. This means that green concept is not accomplished by just manufacturing green products. Third, although a lot of proposals have appeared as green design in exhibitions, most of them are close to craft because they are so hard to be manufactured. Manufacturing is the first consideration for products. These three issues are enough to explain why green concept is complicated in manufacturing products. If they are not solved, the green concept is just a fiction. So if this study proposes a turning point against blind green-oriented atmosphere, it will be meaningful enough.

Through the research on the design evaluation index of parent-child interactive game furniture, it is convenient for designers to quantitatively analyze the design advantages and disadvantages of related products, which is of positive help to control and improve the design quality. Combined with AHP and TOPSIS, this study proposes the evaluation model of three design criteria and 26 design indexes. After expert scoring, calculation, and consistency test of each index, the weight value of each design index is obtained, and the index is classified according to the importance of each index. Finally, eight essential indicators, eleven secondary indicators, and seven general indicators are classified. A case study was conducted with TOPSIS, and the design samples of three parent-child climbing game furniture were analyzed. Finally, the three samples' relative proximity was 0.505, 0281, and 0.640, respectively. The research shows that the AHP-TOPSIS method can scientifically and effectively sort and screen the advantages and disadvantages of design schemes and provide a reference for the research and development of related products.

The aim of this study was to investigate the effects of socio-demographic and health-related perceptions and twenty dietary behaviors on the superiority and preference, convenient use of and purchase motives of vegetables among 370 women(mean age 43.9) in Seoul and metropolitan and Gangwon area. Data was collected using a questionnaire developed in advanced studies. Almost all subjects rated vegetables more predominantly than grains or meats on the basis of health, diversity, and convenience to purchase. Recognition of healthly funcions of diet, purpose of diet and some dietary behaviors had influence on preference for vegetables. Those who recognized that diet had the function of disease control and prevention, knew the healthy options vegetables provide us, such as, preventing us from geriatric diseases, good sources of vitamins and minerals and considered other motives aside from health issues. From Pearsons's correlation analysis, it was revealed that sufficient time for meal preparation and pleasant eating and desirable life style and dietary attitudes, and a better understanding of nutrition were positively correlated with consumption of more vegetables and convenient use of vegetables. The subjects who recognized the ability of food to help prevent diseases, had a preference for vegetables and attitude to use nutritional knowledge and also considered the nutrition values of vegetables and environment friendliness. Everyday use of vegetables such as consuming a variety of different vegetables, a families favorite vegetables and variation of cooking methods had correlated positively with purchase motives. Therefore to encourage consumption of vegetables, it is important to notice three points continuously; first, practical information of nutritive values of vegetables, the contribution of vegetables in current animal protein foods centered diet and healthful functionalities. Second, the importance of regular diet and steadfast attitude and lifestyle. Finally, the quality of the market where the products are bought such as, quality control of freshness, sanitation, expression of producer and a pleasant environment to shop in.

Food consumption trends in Korea are becoming more health-oriented, and consumers have become interested in high-quality foods that are also beneficial to health. The goals of this study are to examine consumers' impressions of black garlic and to investigate the preferred optimal attribute combinations related to black garlic. To do this, a survey of 352 consumers was used to analyze the current status of consumer purchases of black garlic. A conjoint analysis was conducted to analyze certain aspects of consumer preferences, such as price, health functional food certification status, processing type, and taste. Consumers' purchase experiences with black garlic were relatively few, but those with purchase experience reported that they consumed it mainly for their health. The results show that consumers are not satisfied with the taste and flavor of black garlic despite their perceiving it as a beneficial food for health. Despite the fact that consumers' purchase intentions were found to be low, it can greatly increase if improvements in price, flavor, and taste can be realized and if offering substantial benefits. The results of the conjoint analysis of the preference attributes of black garlic products are as follows. Consumers considered price among the four attributes as most important. The taste of black garlic and the processing style were similar in terms of importance, and health functional food certification was less important. Finally, the results suggest that continuous improvements in price and flavor are needed to spread the consumption of black garlic.

Mastitis is a common and serious infection of the mammary gland in dairy cattle and has a major economic impact on the production of milk and dairy products. Bacterial mastitis is caused by several pathogens and is most frequently associated with coagulase-negative staphylococci (CNS). Although CNS are typically associated with subclinical or mild mastitis, the importance of CNS has increased as these pathogens have emerged as predominant mastitis-related pathogens in many countries. CNS can cause persistent infections, resulting in increased milk somatic cell counts and thereby affecting milk quality and decreasing milk production. Globally, Staphylococcus chromogenes, S. epidermidis, and S. simulans are the predominant CNS species in dairy cattle mastitis. Antibacterial resistance of CNS varies with species, and most CNS are susceptible to vancomycin and resistant to penicillin and tetracycline. As the most frequently isolated CNS species, some strains of S. chromogenes exhibit phenotypic resistance to ampicillin, erythromycin, oxacillin, penicillin, and tetracycline. Some strains of S. epidermidis and S. haemolyticus are only susceptible to vancomycin and rifampicin. Therefore, more studies are needed to achieve the control and prevention of CNS as environmental pathogens.

In this study, in order to achieve the before-mentioned study purpose, the importance of developing the new product, the relationship with the design, and the design element for developing the new product were considered. In order to extract the importance of the design element which is applied to the development of the new product design, the research model about the induction of the priority was created, the evaluation items were instituted, and the demonstrative research approach was performed in order to recognize the relationship among those elements. Firstly, in the process of selecting the items for the application, 14 evaluation elements which were extracted through the advanced study data were grouped in 4 kinds of dimensions, and the properties which are related with the Digital TV product were composed up of 36 items. Through the factor analysis, by decreasing the detailed standard for the evaluation of 36 items, the parsimony was secured, and the characteristics which the various items contain induced into one factor. Secondly, the detailed factors which were united into one factor went under the paired comparison as one by one through AHP again, and then the importance degree was generated. First of all, as the first stage of AHP, the decision making factors which affect the whole achievement of purpose of the decision making were classified as in a hierarchical style. From these research results, it was known that the functional factor and esthetic factor in the process of designing the new product are the major affecting variables, and it was confirmed that in case of the Digital TV products group, the factors such as the high quality of picture, big screen, user interface, sound, product reliability, style, size, indoor reproduction, and guarantee are the main factors which influence the need of the consumers in purchasing products.

We know very well the importance of water. Recently, we perceive the truth that water influence the quality of products and we must pay for it. Besides, we recognize why the water treatment is indispensable for life as well as industries. The variation of environment changes the natural resources and threatens the human life. Now, we cannot get water freely from nature. We should find new processes which are effective and inexpensive. We believe that the membrane technology can suggest the new way of water treatment. I'd like to explain the situation of water resource and the membrane processes by UF/MF membranes. I'll also introduce several case studies in this lecture. Till now, about 10 MF/UF systems were established in Korea. Of course, the usage of MF/UF for water treatment is beginning stage in Korea. But the future prospect is very good. Korean government has been developed various kinds of membrane processes for the purpose of drinking water, water reuse, development of new water resources and water related technologies, etc. In near future, maybe we will meet serious water problems, water deficiency and contamination. Fortunetely, we can suggest the membrane process for solving those problems. Membrane technology will be the base of clean technology.

As crude oil with heavier and/or highly oxidized components prevails, purification technologies such as desulfurization, denitrilization and demetalization have become important issues to control contents of sulfur and other impurities affecting the quality of petroleum. Also, the importance of catalyst technologies related with crude oil purification has been emphasized to control the production and yield of products. In this paper, technology trends of impurity removal such as sulfur, nitrogen and metal components from crude oil and catalysts related with purification of crude oil were studied through patent analysis. The patents published or registered in Korea, U. S. A., Japan, and Europe from mid 1970's to 2009 had been analyzed based on the application tendency, the distribution of major applicants, and their active indices, etc. The technology flow was figured out to see the technology trends.
