Assuming that life of urban transit signaling is about 20 years with the flow of technology development, Seoul urban transit will be required to prepare for improvement soon. The highly developed countries preceding several levels rather than Korea are faced with commercial service, which uses RF, ATC and ATO in Train Control System. European highly developed countries in the field of railroad have been progressing standardization and technology development of signaling associated with related manufacturers for direct operation between nations. For that, a effective train control system with radio beyond control levels by the existing wayside-onboard communication is in a developed and used stage. The systems, which advanced countries have been progressing, seem to be applied to domestic within 5 years from now. At present, there are no countries using CBTC for service throughout the world. So, this is investigated to focus on the routes ready to be installed with completed CBTC and trying to introduce the technology. Especially, considerations for economic aspect are mainly reviewed about controlling ability of headway, flexibility, extension aspect and construction cost on the basis of paper examined in NYCT.

Most of biomaterials come in direct contact with the body, making standardized methods of evaluation and validation of biocompatibility an important aspect to biomaterial development. However, biomaterial validation guidelines have not been fully established, until now. This study was to compare the in vitro behavior of osteoblasts cultured on nanomaterial $TiO_2$ surfaces to osteoblast behavior on culture plates. Comparisons were also made to cells grown in conditioned media (CM) that creates an environment similar to the in vivo environment. Comparisons were made between the different growth conditions for osteoblast adhesion, proliferation, differentiation, and functionality. We found that the in vivo-like system of growing cells in concentrated CM provided a good validation method for biomaterial development and in vivo implant therapy. The $TiO_2$ materials were biocompatible, showing similar behavior to that observed in vivo. This study provided valuable information that would aid in the creation of guidelines into standardization and evaluation of biocompatibility in $TiO_2$ biomaterials.

Survey reports of election opinions consist of numerous cross-tabulations between socio-demographic variables and political opinions including preferred candidates. Since socio-demographic variables are related each other, duplicate interpretations arise. The aim of this study is twofold: The first is to separate the effects of socio variables such as education, occupation and income from the effects of demographic variables such as region, sex and age. The second is the visualization of multiple cross-tabulations in low-dimensional space by extended doubling technique of correspondence analysis. Survey researchers may get some help from this study to present their survey results more lucidly and visually.

The past research have suggested that the Inter-Organizational E-Commerce based on the Inter-Organizational Systems(IOSs) has direct impact on the Inter-Organizational Relationships(IORs) in general. Considering the importance of this issue, however, few empirical research have been conducted. The objective of this study is to examine the impact of the level of Inter-Organizational E-Commerce on the performance of IORs in particular. Reviewing the literature, we suggested a research model and developed ten hypotheses to be tested. We conducted a survey and collected data from 125 companies which were using. EDI systems. The data were analyzed using LISREL 8.30. The major findings are: (1) The volume of E-Commerce has a positive impact on the commitment of trading partners. (2) High quality of information sharing and high degree of standardization improve the trust and the commitment between trading parties. (3) The trust and the commitment are critical precedent variables of cooperation. (4) The more partners cooperate each other, the more transaction cost will be reduced and as a result, the more financial performance will improve. A discussion on the result of the hypotheses test is followed by a discussion on the academic and practical implications of this study.

Korea faces challenges from the recent development catch-up countries and the absence of catch up incentives. For Korea to solve the issue of post catch-up problems and create a new development path based on creative innovation, there is an urgent need to secure a system design capability for the production of creative knowledge and talent that can create a competitive society. However, the conservative inclination and a lack of a customer-oriented attitude of Korean universities and professors leads to a standardization of talent and a passive restructuring of the curriculum by universities instead of a direct correspondence with the demands of companies and society. The compatibility of Korean university education with the demands of society remains the lowest in the world and creative education in Korea faces a difficult situation. The world is transforming from a knowledge-based economy to a creativity-based economy and a competitive society will led by creativity, not by knowledge. The success of a country in nurturing creative talent will determine its future national competitiveness. For Korea to be become a global leader in the new era of creativity, it needs to make proactive preparations. It is imperative for Korea to transform the educational system from the previous cramming system to a creativity-nurturing system.

Pursuing sustainable development throughout society and industry and the field of environmental policy, each international organization or nation has performed international standardization projects on environmental management activities for their system as well as environmental assessment for a product such as life cycle assessment (LCA) and life cycle inventory database (LCI DB), and the environmental aspects have been increasingly demanded as crucial evaluation specifications. Moreover, the conventional environmental policy, which represents the direct-control, has been more dependent on the market forces and product itself after the Climate Change Convention., and the Integrated Product Policy (IPP, EU) is applied vigorously to strengthen global competitiveness of a product and to achieve the effect of environmental improvement for it. According to change of the international railway market, the value of Eco-Design has been increasingly important in developed countries including EU. Thus, each country is establishing its own guidelines, software and database for each product, and developing new policies through Eco-Design with practical results in marketing. To react this and develop Korean railway as an environment-friendly industry with priority to other transportation system as well as maintain high place in technology, the direction of RACE software development of main function is introduced, which is exclusively used for EMU to assess both environmental and economic aspects with LCA and eco-efficiency (EE).

Background: Kidney cancer has shown an increasing trend in recent decades. This study aimed to determine change in the incidence rate between 2003 and 2009 in Iran. Materials and Methods: In this study, national cancer registry data were used. Crude incidence rates were calculated per 100,000 and age-standardized incidence rates (ASRs) were computed using the direct standardization method and the world standard population. Significant trend of incidence rates was examined by the Cochran-Armitage test for linear trend. Results: A total of 6,944 cases of kidney cancer were reported. The incidence cases increased from 595 patients in 2003 to 1,387 patients in 2009. Sex ratio (male to female) was 1.67. ASR also increased from 1.18 in 2003 to 2.52 in 2009 per 100,000, but the increasing trend was not significant. Conclusions: A slow increasing trend of incidence rate was observed in the study population. This may be due to an increase of risk factors. It is suggested to perform a study on risk factors for the cancer.

The principal objective of this study was to develop a standardized recipe for the large-scale production of Bibimbab, bean sprout bab, and fried rice. The recipe was standardized as follows. We collected and recorded the quantities of ingredients and production procedures currently used by cooks in the contracted foodservice management company and in hotel-based Korean restaurants. According to the food preferences of Koreans, we selected 3 rices; Bibimbab, bean sprout bab, and fried rice. We then developed a revised recipe and evaluation form. Our sensory evaluation was conducted by 30 taste panels using a JAR(just- about-right) scale. We developed a standardized recipe for 3 rices. Yield, portion size, temperature, preparation time, equipment, cost, ingredients, weight of ingredients, method, and critical point were recorded in the developed recipe. We utilized the factor method and the percentage method for recipe adjustments, and we devised a direct measurement table for Bibimbab, bean sprout bab, and fried rice.

Objectives : The moxibustion is the method in using the heat stimulation made of attached and burned a moxa or other herbal materials on a healing point or acupuncture point and the chemical stimulation of a resin made from burning them. We need to standardize the characteristics of moxa combustion in order to get more systematic and objective result in operation mechanism and effects and then get more clinical abilities in these fields. Methods : In this study, using of labview system on the moxibustion. 1. we studied relation the size of barley and jujube seed with the moxa cone's peak combustion temperature and then measured and compared the moxa cone's peak combustion temperature by tonification and sedation method. 2. we measured the peak combustion temperature of indirect moxibustion. Results & comclusions : 1. When we measured a direct moxibustion's combustion temperature, the jujube seed sized moxa cone's peak temperature was higher than the barley sized moxa cone's when it burned and the time to peak temperature of the barley sized moxa cone was shorter than the jujube seed sized moxa cone's. 2. When the direct moxibustion was burned by the tonification and sedation method, the sedation method's peak temperature was higher than the tonification method's, the tonification's time to peak temperature was shorter than the sedation method's. 3. When we measured the temperature of the moxa combustion in the kinds of sliced herbal materials, the peak temperature of indirect moxibustion with a ginger when it sliced a 1.3mm size and a 1.5mm size was degreed within $40^{\circ}C$ to $52^{\circ}C$ and the peak temperature of indirect moxibustion with a garlic when it sliced a 1.7mm size was degreed within $46^{\circ}C$ to $62^{\circ}C$.
