To improve the quality and functionality of the low salt squid Jeot-gal, extracts from three types of medicinal and edible plants (bay leaf, green tea, pine needle) were added. The quality characteristics, bioactivities, and shelf-lives of these preparations were determined at three different fermentation temperatures. The pH decreased more rapidly at higher temperatures, while the amount of volatile basic nitrogen (VBN), total viable cells, and amino nitrogen ($NH_2$-N) increased. The shelf-lives of Jeot-gal with natural plant extracts at $10^{\circ}C$ were 34~35 days, similar to the control. The major free and compositional amino acids of Jeot-gal were glutamic acid, proline, and alanine, while the major nucleotides (and related compounds) were hypoxanthine and inosine. In bioactivity assays, samples supplemented with plant extracts showed higher bioactivities than the control. The DPPH radical scavenging activity of ethanol extracts from Jeot-gal were stronger than the water extracts; in contrast, the water extracts were stronger for hydrogen peroxide scavenging activity. However, superoxide dismutase (SOD)-like activity and ${\beta}$-glucuronidase inhibitory activity were moderately low at 20 mg/mL. Based on sensory evaluation results, the quality of low salt squid Jeot-gal with natural plant extracts is similar to the control. Therefore, low salt squid Jeot-gal with natural plant extracts can be commercialized as a functional fermented food.

The effects of roasting temperature and time on the antioxidant activities of tartary buckwheat were investigated. Compared to raw seeds (2.05 mg TAE/g), seeds roasted at $175^{\circ}C$ for 5 min showed significantly higher total polyphenol content (p<0.05), while those roasted at $250^{\circ}C$ for 10 min showed significantly lower total polyphenol content (2.77 and 2.56 mg TAE/g, respectively). The electron-donating abilities of tartary buckwheat seeds increased with an increase in the roasting time at lower temperatures (p<0.05). However, seeds roasted at a higher temperatures ($250^{\circ}C$) for 10 min showed significantly lower electron-donating abilities (p<0.05). Seeds roasted at $175^{\circ}C$ showed adequate L values, regardless of the roasting time. In contrast, seeds roasted for 10 min at $250^{\circ}C$, showed markedly lower L values. Our results suggest that the roasting temperature and time must be controlled to produce high-quality tartary buckwheat products.

Makgeolli, known as takju, is a traditional alcoholic beverage which is native in Korea. It is made from various rice and other cereals. This study is carried out to compare the physicochemical characteristics and functional quality of makgeolli from various rice cultivars according to different amylose contents and amylopectin compositions. The 'Goami2', 'Goami3', and 'Goami4' have high amylose contents and lower proportional degrees of polymerization (DP) 6~12 and higher proportions of DP 13~24 in amylopectin of milled rice. Various variations are shown in pasting properties (viscosities) and gelatinization characteristics, and it is supposed to be related to both the amylose contents and the amylopectin compositions of raw rice. The makgeolli is being manufactured by using the 2-step-brewing method. The makgeolli is analyzed for alcohol contents, pH levels, total acids, Hunter color values and organic acid compositions. The makgeolli of 'Goami2', 'Goami3', and 'Goami4' have showed higher makgeolli yields, lower ethanol contents and less sweetness than other cultivars, and they also have high non-digestible carbohydrates contents which are derived from their high non-digestible carbohydrates contents in milled rice. Therefore, we are able to suggest that it is necessary to improve the makgeolli fermentation processes of 'Goami2', 'Goami3', and 'Goami4'.

In parallel with advancement of the industrial society and accompanied quality-of-life improvement, jewelry is now rather viewed as one of common accessories used in daily life, than as a luxurious item as treated before change of perception about it in the past, attracting thus gradually multiplying demand for it. Thanks to rapid spread of multi media like the Internet, an increasing number of people have come to develop great liking for exceptional design and unique format of jewelry products. Following drain of their reserves, natural gems are unlikely to meet the demand for them fully in the future. As a consequence, it seems essential to rely on synthetic, artificial, imitation jewelry or organic substances and quasi-mineral in amorphous structure for substitute jewelry. Since synthetic jewelry has such a great potential as substitute jewelry, it is expected to maximize added value to jewelry if and when accompanied with development of creative design and upgrading of processing technology for jewelry, in addition to various types of synthetic jewelry and glass that have been already put in use as substitute substances. Synthetic jewelry is thus believed to be able to greatly contribute to progress of the jewelry industry. In many countries of the world, jewelry and gem industry has been regarded as one of promising sectors vital in enriching the national wealth. In this context, the Korean Ministry of Finance and Economy announced in July 2007 "an activating policy for the jewelry and gem industry, declaring to cultivate and grow it to be new engine for the nation's growth". The present paper thus aims to conduct a study exclusively on cutting design of synthetic jewelry as a part of measures to activate the jewelry industry in Korea. Efforts are made to develop designs for jewelry that are unique and different from the conventional stereotyped form of polishing and are added with color, pattern and fashionable cutting. Priority is given in this regard to designing jewelry that may attract general public and may be shared by public beyond the limit of conventional design for jewelry and producing products that stand in contrast with other products. By upgrading the quality of jewelry design, competitiveness of the jewelry industry may be ensured and the creative area of jewelry design may be expanded by far.

The CLA used to add in diet was chemically synthesized by alkaline isomerization method with corn oil. Pigs were divided into 5 treatment groups (4 pigs/group) and subjected to one of five treatment diets (0, 1.25％ CLA for 2weeks, 2.5％ CLA for 2weeks, 1.25％ CLA for 4weeks and 2.5％ CLA for 4weeks, CLA diets; total fed diets) before slaughter. Pork loin were collected from the animals (110kg body weight) slaughtering at the commercial slaughter house. Manufacture press ham using CLA accumulated pork loin were vacuum packaged and then stored during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. Samples were analyzed for texture characteristics, sensory evaluation, fatty acid composition and CLA content. There was no significant difference in texture among control and CLA treatment groups. It was not clearly changed by storage time. No remarkable differences were found in sensory properties (color, flavor, texture and acceptability) between control and CLA treatment groups. It was not clearly changed by the passage of storage time. In the change of fatty acid composition, the contents of oleic, linoleic and arachidonic were decreased by dietary CLA-supplementation, whereas the increase level of CLA-supplementation resulted in the higher palmitic and stearic acid than control. As dietary CLA was increased in feed, the content of CLA in pork was increased.

The purpose of this study is to present the specific ways of successful localization by analyzing the success and failures case for localization within the framework of the strategic models through a theoretical background and strategic models of localization. The strategic models of localization are divided by management aspects such as the localization of product and sourcing, the localization of human resources, the localization of marketing, the localization of R&D, harmony with a local community and delegation of authority between headquarters and local subsidiaries. The results, by comparing and analyzing the success and failures case for localization of individual companies operating in India, indicate that in terms of localization of product and sourcing, there are successful companies which procure a components locally and produce a suitable model which local consumers prefer and the failed companies which can not meet local consumers' needs. In case of localization of human resources, most companies recognize the importance of this portion and make use of superior human resource aggressively through a related education. In case of localization of marketing, It is found that the successful companies perform pre-market research & management and build a effective marketing skills & after service network and select local business partner which has a technical skills and carry out a business activities, customer support, complaint handling with their own organization. In terms of localization of R&D, the successful major companies establish and operate R&D center to promote a suitable model for local customers. In part of harmony with a local community, it shows that companies which made a successful localization understand the cultural environment and contribute to the community through CSR. In aspect of delegation of authority between headquarters and local subsidiaries, it is found that most of Korean companies are very weak for this part. there is a tendency to be determined by the head office rather than local subsidiaries. Implication of this thesis is that Korean enterprises in India should carry forward localization of products and components, foster of local human resource who recognize management and system of company and take part in voluntary market strategy decision, wholly owned subsidiary, establishment and operation of R & D center, understanding of local culture and system, corporate social responsibility, autonomy in management.

To increase utilization of Korean sweet persimmon, white breads containing sweet persimmon were prepared and those characterizations were evaluated. WB (white bread without persimmon), FPB (white bread containing 30% (w/w) persimmon flesh), and WPB (white bread containing 30% (w/w) whole persimmon) were prepared by straight dough method. Specific volumes of WB, FPB, and WPB were 3.51, 2.99 and 3.21 $cm^3$/g, respectively. Loss of bread of WB, FPB, and WPB were 9.81, 7.78, and 8.86%. With addition of sweet persimmon in bread, the lightness (L) was decreased, and the redness (a) and the yellowness (b) were increased. DPPH radical scavenging activity, one of antioxidant activity, of WB, FPB, WPB at concentration of 10 mg/mL was $12.39{\pm}0.135$, $14.57{\pm}0.01$, and $19.57{\pm}0.44%$, respectively. Total phenolic contents of WB, FPB and WPB were $177.05{\pm}5.52$, $185.26{\pm}0.79$, and $216.24{\pm}5.47$ mg GAE/g. Hardness of WB were 175.33 Dyne/$cm^3$, and the value was decreased in FPB and WPB. In sensory test, FPB acquired relatively high points in texture, flavor, taste, and overall acceptance.

The present mobile phone industry has significant effect on the domestic economy and has taken root as the core item that has the responsibility to lead the Korean economy for a considerable period of time. As the mobile phone market becomes gigantic, the mobile phone is being used by people in broader age bracket, and functions or designs preferred by people of various age are getting more diverse. Like that, as the mobile phone has greater effect on and meaning in our daily lives, consumers of mobile phone have growing expectation of the mobile phone Now, the core function of voice communication via the mobile phone is not a great concern to consumers. But the function, such as more convenient and friendly information input and output, processing and storage, and the design, which is more sophisticated and optimized for the user environment, are being demanded, not just the simple voice communication. And as the modern design is getting more similar to the objects of traditional high art consumed by consumers every day, the aesthetic aspect of design can play an important role, as the factor that differentiates the product, in creating new value which forms the spiritual and emotional value of human beings to improve the quality of living, and in addition, the willingness of consumers to buy is determined by the design that they prefer the most. Like that, a new design of mobile phone based on a new dimension and preferred by the consumers the most is urgently required to be developed by shedding light on the factors related to the preference of consumers on the basis of the analysis on the aesthetic aspect, which can be said to be the most critical factor in the design process. Therefore, this study aims to identity the common preference and different factors of aesthetic aspects through the analysis on the aesthetic aspects of the mobile phone preferred by users among countries, and figure out the formative artistic factors of aesthetic aspects that are considered to be important, in order to propose the guideline on the aesthetic aspect of mobile phone that can be applied to the design of mobile phone practically.

To improve the social and economic position of the disabled people and secure their human rights, an integrated society should be buill. To build such a society, an adequate access should be provided to the movement or in using buildings or facilities. The inconveniences from social life on the part of the disabled people might not result from their impairment or disability, but from physical and social barriers in the environment surrounding them. Therefore, it is necessary to reconstruct entire systems of the society as a disabled people-friendly structure in order to remove those barriers, make them stand their own feet in our communities and freely participate in the social activities. This will eventually lead to build a society in which all people including the disabled people can use those facilities in a more convenient way. It is almost impossible for the disabled people to safely and conveniently access to and use facilities and equipments and freely move to their desired places, without any help from others in Korea. Even though, there are currently many disabled people-related convenience facilities, they have been independently built without a connection with other facilities and buildings, thus not greatly useful. Even when convenience facilities have been built, mostly they are superficially set up; therefore, in many cases, the disabled peOple cannot use those facilities. In this. research, I tried a new concept of mobile wheelchair lift design, which the disabled people can operate without restrictions, when using the public facilities. The key to this research was to develop the existing import-oriented simple functional products to a new system with functional safety and high quality orientation. Also, this research aimed at bringing an. import substitution effect, as well as preempting the mobile wheelchair lift market by advancing into overseas markets through application of new image designs in the field of disabled people aid equipments.
