This study was to investigate which predictors influenced the wish to undergo cosmetic surgery according to experience of cosmetic surgery in female college students. A cross-sectional descriptive design was used with self-report questionnaires, which were completed by 254 subjects. Data was analyzed with t-test and regression. There were statistically significant differences in acceptance and social motivation of cosmetic surgery and the wish to undergo cosmetic surgery in the future between the two groups. Body area satisfaction and acceptance of cosmetic surgery were significant predictors to the wish to undergo cosmetic surgery in the non-experienced group. The significant predictor of the wish to undergo cosmetic surgery for the experienced group was acceptance of cosmetic surgery. The findings from this study suggest that there is need to different approaches to discuss or council for wish to undergo cosmetic surgery according to individual cosmetic surgery experience.

This empirical study is to explain critical success factors for building effective regional IT cluster from the literature reviews which have some limitations, and is to suggest new key factors from the views of Regional Innovation System and Sectoral Systems of Innovation. For building successful cluster, the new key factors not only stress on regional networks, the spill-over of tacit knowledge through learning by interacting, institutions which contain regional custom, norms, established practices, culture, and characteristics from the Regional Innovation System, but also emphasize on heterogeneous agents who are interacting by each others from Sectoral Systems of Innovation. From these factors we suggest some strategies for building effective "Daegu IT Cluster" as following; making characterized IT brands which are selected and concentrated based on regional and IT sectoral characteristics, strengthening learning competence of tacit knowledge built in multiple heterogeneous agents network, establishing strong agent networks which are composed of universities, companies, institutes and government, and sharing the institution of mind-opening culture in order to correspond with environmental changes and link to other industrial clusters. By putting above strategies in force, the compatabilities of Daegu region are reinforced. Tacit knowledges spill over and the regional innovation competence are accumulated. Also IT cluster plays core role of employment in Daegu for long term. Especially, "Daegu IT Cluster" changes city's image from medium and small manufacturing city to new industrial city based on high technologies.

Because damages arising from the occurrence of foot-and-mouth disease (FMD) are very great, it is essential to make a preemptive diagnosis to cope with it in order to minimize those damages. The main symptoms of foot-and-mouth disease are body temperature increase, loss of appetite, formation of blisters in the mouth, on hooves and breasts, etc. in a cow or a bull, among which the body temperature check is the easiest and quickest way to detect the disease. In this paper, an algorithm to detect FMD from the hooves of cattle was developed and implemented for preemptive coping with foot-and-mouth disease, and a hoof check test is conducted after the installation of a high-resolution camera module, a thermo-graphic camera, and a temperature/humidity module in the cattle shed. Through the algorithm and system developed in this study, it is possible to cope with an early-stage situation in which cattle are suspected as suffering from foot-and-mouth disease, creating an optimized growth environment for cattle. In particular, in this study, the system to cope with FMD does not use a portable thermo-graphic camera, but a fixed camera attached to the cattle shed. It does not need additional personnel, has a function to measure the temperature of cattle hooves automatically through an image algorithm, and includes an automated alarm for a smart phone. This system enables the prediction of a possible occurrence of foot-and-mouth disease on a real-time basis, and also enables initial-stage disinfection to be performed to cope with the disease without needing extra personnel.

Variable Message Signs(VMS) is one of the important subsystems of Intelligent Transportation Systems (ITS), which is useful for providing drivers with real-time information on traffic, roadway or weather conditions. In order to maximize the effectiveness of the VMS system, it is required to reflect drivers's preference on designing and operating the system. In this context, this study was conducted to develop strategies to deliver the messages in an efficient manner while many other previous studies focused primarily on the contents of the messages, from drivers's perspectives. Drivers's preference on message expression formats and message display orders were investigated through image analysis in the perspectives of a total of 40 subjects. With respect to message expression formats, drivers preferred Gulim or Dodum in font style, middle arrangement of the letters, pictogram combination as opposed to letters only, blank time less than 0.5 sec, appearing message in animation effect, messages in single phase, non-flashing message. In the matter of message display orders, drivers preferred to obtain link or traffic information in the lust place. Then, they desired to be informed of roadway condition and instructions or recommendations for drivers to cope with unexpected events among various messages for traffic condition.

This paper aims to point out that the contemporary textbook is a common cognitive construct, and that the realistic drawings in the textbooks have played an important role in shaping the world recognition. The main subjects of this study are the racial-ethnic illustrations of elementary school geography textbooks, published by the Japanese Ministry of Education, the Japanese Government-General of Taiwan and Korea, the educational association of Manchu. By comparing the same factors in various textbooks, it examines how the temporal and spatial recognition of the world is adjusted by visual representation. The main findings of this study are three fold. First, the world was introduced to the extent of the sum that the census and the classifications of racial and ethnic groups were adopted. And the world appeared later in the year supported by the racial and ethnic minorities. Second, the expressive style of racial and ethnic groups changed from an emphasis on a heterogeneous part as an object of scientific observation in the early stage to a later one with a life culture similar to the reader. Third, racial ethnic illustrations have been used differently depending on the publishing region in the Empire, giving readers in different regions with different images of the same category. In many cases, it was possible to know the politics of representation and the use of certain racial ethnic illustrations. The textbooks of the first half of the 20th century gave great recognition to the people who could not meet with the readers by using the illustrations. A child in the mainland is aware of his position in a "viewing position" while viewing various empire people through the textbook. On the other hand, in the textbooks of the colonial children, they stood in the position of 'being seen', and showed a change in internalizing the position of the mainland along with the expansion of the empire.

In this study, experimental and numerical studies for the synthesis of carbon nanotube(CNT) in methane counterflow diffusion flame have been performed. Methane mixed with acetylene($C_2H_2$) was used as a fuel gas and ferrocene was used as a catalyst for synthesis of CNT. The major parameters was $C_2H_2$ mixing rate and mixing rates were 2 %, 6 %, and 10 %. Characteristics of CNT formation on grid were analyzed from SEM images. the chemical reaction mechanism adopted is GRI-MECH 3.0. Numerical results showed that flame temperature and CO mole fraction were increased with increasing acetylene mixing rate. Experimental results showed that the CNT synthesis in 2% acetylene mixture flame better than that of 6% and 10% acetylene mixture flames. It can be considered that 6% and 10% acetylene mixture flames generated the excessive carbon source and then it interrupted the supplement of the carbon source into ferrocene catalyst. It can be found that the supply of appropriate quantity of carbon source can make effect to synthesis of high purity of CNT.

We sought to define the main motivational factors promoting consumption of Prunus mume products. We surveyed both specialized high-volume consumers and public consumers, and focused on consumption of and preferences for Prunus mume and Prunus mume products. We investigated how products were preferentially consumed, purchase experience, purchase location, purchase price, consumption experience, factors important in a purchase decision, preference factors, dissatisfaction factors, consumption outlook, comments on new processed foods, and activation of consumption. A total of 534 responses were received and data were analyzed using the SAS program (Version 9.1) of the Frequency test; Chi-square test was used to detect significant factors. A greater percentage of high-volume(compared with low-volume) consumers processed personal products at home. The public consumer tended to buy commercial products. However, public consumers who were older, who had higher incomes, and who were heads of households, tended to both buy commercial products and to prepare foods at home. The common purchase methods used by high-volume consumers were internet and direct marketing, but the public consumer frequented department stores and hypermarkets. High-volume consumers observed that commercial products were expensive, and such consumers seemed to be particularly cost-sensitive. The decisive factor triggering purchase decisions in high-volume consumers was the geographical origin of the fruit, whereas the public consumer was more concerned with taste. In public, positive factors were that the product was good for health and had a pleasant taste. Some of those surveyed complained of a lack of variety in Prunus mume products and that the amount of Prunus mume in certain products was low. To promote and increase consumption, convenient-to-eat products with healthy images are needed.

The purpose of this study was to examine the effectiveness of family-friendly management in 501 family-friendly certified firms and to analyze organizational and social outcomes outlined by the firms. In addition, this study aimed to discover ways to promote family-friendly management by investigating the effects of ongoing support to certified firms, including family-friendly consulting and workplace training. The results showed that certified firms administer family-friendly workplace policies at a satisfactory level, while their management of policy indices and outcomes were not effective. The finding suggests that family-friendly management indices need to be aligned with firms' substantial outcomes. An improved organizational image and trust were major organizational outcomes of family-friendly management, and an enhanced CEO perception and a culture centered on gender-equality were significant social outcomes. These outcomes need to be promoted to attract organizations to engage in family-friendly management. The finding further implies the important roles of organizations in cultivating family-friendly environments in society. Finally, the certified firms with ongoing consulting and training support exhibited higher levels of family-friendly management and organizational and social outcomes. This study sheds light on the importance of long-term, systematic efforts by organizations in fostering family-friendly management and achieving organizational and social outcomes.

In order to survive the on-going natural resource war, Korea needs various efforts such as enhancing self-exploitation ratio, increasing the supply of new-reuse energy, strengthening cooperation with resource rich countries. Central Asian countries are geometrically far away from Korea. However, Korea should try to develop political, economic and ethnic relationship with those countries into much higher dimension to secure various natural resources. Major countries including U.S., EU. Japan and China are approaching Central Asian countries with long term perspective. Improving country-image through enlargement of ODA is the first concern of those countries. Korea should try to follow their practices. Government should try to improve Korea's image in the first place and lead economic cooperation with very detailed supportive measures to induce Korean firms' investment into the Central Asian countries. In the due process, a lot of information about those countries' political climate, social situation, ethnical composition, major religions, educational system, current state and structure of economies and industries, etc should be made available to Korean firms.
