Seoul Metro Line 9 (SML9) is the first subway line that private capital invests in Korea. SML9 will cross Seoul, linking the Gimpo Airport to the Gangnam district (25.5km) opening in the first half of 2009. SML9 has a new model in Korea constructed by metropolitan government and private company and operated by specialized public transportation service provider. SML9 is confronted with tough environment of stagnated public transportation and strong competitor, Olympic city expressway. And SML9 is under pressure for showing high efficiency as non-governmental organization from both customers and government. Consequently SML9 must lead the maximum efficiency by using its material and human resource. It is necessary that SML9 raise a competitive power and display its ability in active collaboration with relative organization and company. Hereupon, I propose renovation plans from viewpoint of operation field of SML9, (1) efficient train scheduling regime focusing on the combination of express and local train (2) close connection of other mean of transportation and (3) effective connection convention with Airport Railroad (AREX) as the line connected directly.

Radio Frequency Identification (RFID) is a common term for technologies using micro chips that are able to communicate over short-range radio and that can be used for identifying physical objects. RFID technology already has several application areas and more are being envisioned all the time. While it has the potential of becoming a really ubiquitous part of the information society over time, there are many security and privacy concerns related to RFID that need to be solved. This paper proposes a method which could protect private information and ensure RFID's identification effectively storing face feature information on RFID tag. This method improved linear discriminant analysis has reduced the dimension of feature information which has large size of data. Therefore, face feature information can be stored in small memory field of RFID tag. The proposed algorithm in comparison with other previous methods shows better stability and elevated detection rate and also can be applied to the entrance control management system, digital identification card and others.

We have studied the narrow viewing angle liquie crystal displays (LCDs) using a hybrid aligned nematic liquid crystal (LC) cell driven by a fringe field. The device using a LC with positive dielectric anisotropy has a relatively low transmittance. This paper describes how to improve light efficiency by optimizing electrode structure. The results show that the device exhibits a high transmittance of 90%, low driving voltage and narrow viewing angle less than $20^{\circ}$ along horizontal direction which is highly effective for private display application.

The application of cloud computing to many industrial domains is rapidly increasing, and domestic and foreign cloud service providers are actively conducting business. In the domestic cloud market, it is necessary to establish an ecosystem with partner operators that work closely with private cloud service providers. In this paper, to create such an environment, we propose a framework that can evaluate the capabilities of partners required for cloud service providers to establish specific business strategies. The framework proposed in this study establishes criteria for evaluating partners' competencies and applies a decision-making model such as fuzzy AHP for evaluation. Eventually this will help not only to expand the domestic cloud market but also to strengthen the competitiveness of domestic cloud partners through the growth of the domestic cloud market.

In this paper, a low price ultrasound image processing system is developed using DSP and PC. Ultrasound for image is generated by the 32-channel transducer. Ultrasound image is captured by DSP instead of the private image grabber board. Display of image and image processing algorithms are performed by PC. The image processing algorithms based on GUI are realized by software. So users without knowledge of image processing can perform the image enhancement more easily.

The growing socio-economic effect caused by science and technology requires public to participate in policy-making process, which makes government to boost public understanding of science(PUS). Government has also exerted to construct infra for PUS. However results are not so meaningful. The government-funded science museum has mainly provided the program for students. Besides, science broadcasting channel has recorded the worst viewing rate. Meanwhile, some of the private sector-manufactured contents have attracted public attention in recent years, which is realized by considering elements such as an interesting topic selection, use of outside experts, two-way communication system, level adjusting for public through flexible running system. This study analyze podcast based program, face to face lectures, display contents by private industry, fab lab etc. on the base of the reciprocal PUS model to sort out the reason they have successful results. Futhermore, it argues that government should intensify support for private sector and create synergy effect by cultivate collaboration system between government and private sector to enhance the efficiency of PUS and offers public policy to realize the plan.

The purpose of the research is to furnish basic data for efficient and effective marketing by examining the correlation how a certain element effects on customer's selection behavior, when they choose private label branded clothes at the store of giant discount store like E-.mart, Home-plus, Lotte-mart and 2001 outlet. We come to the following conclusions through such procedures; What we found on this study is that main factors of decision related purchasing garment of private brand in giant discount store is based on the sales price, quality of products and needs of customer's using. Further to this, in terms of choice activity in private brand clothes, we realized the price value is depend on the resonable price with the items because nowadays most customers can be compare to other discount store around their shopping place including trend of garment and quality of products. The order of the general inclination in selection behavior of private branded garment in giant discount store is as follows; Sales price > style & trend > quality of product and substantial convenience > display and prompt buying. Judging from the conclusion of the research we noted that customer's satisfaction comes from their target price to supply substantial needs and in terms of styling of clothes should be considered current trendy compared to national brand as well.

Objective: The aims of this study were to assess the direction and degree of lip-line cant in Korean adult orthodontic patients and to identify the effects of sex and age on changes in the cant severity. Methods: In this cross-sectional retrospective study, lip-line cant was measured in the frontal photographs of 585 Korean patients (92 men and 493 women) aged 18-48 years. The outcome variables (direction and degree of lip-line cant) were assessed in terms of predictor variables (sex, age, sagittal skeletal relationship, and menton deviation angle). Results: The direction of lip-line cant did not differ according to sex, age, or skeletal classification. Patients had $1.6^{\circ}$ of lip-line cant on average before orthodontic treatment. Middle-aged adults displayed a significant trend toward a lower degree of lip-line cant compared to younger adults (p < 0.01). Multiple linear regression analysis showed that the degree of lip-line cant was weakly negatively correlated with age (p < 0.001). Conclusions: While the direction of lip-line cant did not differ according to the parameters explored here, the degree of cant was correlated with age in adults, independent of menton deviation. Specifically, middle-aged adults tended to display significantly lower degrees of lip-line cant than did younger adults.

The purpose of this study is to classify the attitudes toward fast fashion into groups and analyze the differences of the self-consciousness, and make-up behavior by groups. Questionnaires are being administered from 179 high school girls living in Deagu metropolitan City. Frequency, factor analysis, reliability analysis, cluster analysis, ANOVA, Duncant-test, and ${\chi}^2$-test are all used for data analysis. Our findings are as follows. The attitude toward fast fashion shows a significant correlation with the sub-variable self-consciousness and make-up behavior. Attitude toward fast fashion is being categorized into convenience focus, fashion focus, design focus, and season focus. Self-consciousness is social self-consciousness, social anxiety, private self-consciousness, and private anxiety. Make-up behavior is positive effect, fashion leader, and conformity. Attitude toward fast fashion is classified into three groups: disposability, fashionability, and low interest of fashion. The groups show a significant difference in the self-consciousness, and make-up behavior. Groups display no distinctions between the sub-variables in the actual conditions of cosmetics such as a first time for make-up and frequence of visit.

Mukbang is a type of foodcasting where a host records or streams their eating rituals for audience consumption in live format. With origins in South Korea via the online broadcast genre found on Afreeca TV in the mid-2000s, the phenomenon has since found global popularity. Its development as a full-fledged genre is based on a communication culture that invites people to a meal rather than to talk to one another; viewers watch in silence as a host consumes a copious number of dishes from Korean gastronomy to fast food to other ethnic cuisine on display. An invitation to eat means the beginning of a public relationship that quickly turns to a private shared experience. This study analyzes several Mukbang video postings and makes use of Linden's culture approach model to provide a view toward a number of cross-cultural connections by Koreans and non-Korean audiences. Prior to the study, 10 Korean eating shows were selected and used as standard models. Korean Mukbang mainly consists of eating behavior and ASMR, with very few storytelling or narrative devices utilized by its creators. For this reason, eating shows make a very private connection. In other ways, this paper shows how 28 Mukbang-related YouTube contents selected by Ranker were evolving and examined through notions of acculturation and reception theory.
