Recently, due to the open architecture of the internet and wide spread of internet users, the cyber terror threatens to the network\`s weak point are tending grow. Until now, information security solutions are passive on security host and particular security system. This passive information security solution is weak from the attacks through the networks connected worldwide internet systems, and has limitation on the defense against cyber terror attacks. Therefore, network level integrated security function must be provided. In this paper, we consider technology limitations on the information security problems and its environment. Then we present the architecture and functions of policy-based information security services for network level active information security function. This paper also includes design of target system, which provide information security services. Finally, we discuss network level system deployment direction and discuss with Network Security Simulation.

Aspergillus Infection is a major.cause of mortality in individuals with depressed cell-mediated immunity. Despite therapy with intravenous amphotericin B and oral antifungal agents, high mortality has been reported among heart transplant recipients. We experienced two cases of pulmonary aspergillosis among 15 heart transplantation cases. Both cases were similiar in terms of age, time of diagnosis, and medication. Percutaneous needle aspiration biopsy revealed Aspergillus fumigatus in both cases. The thirst case showed multiple aspergilloma on both lung fields and were treated by IV Amphotericin B and oral itraconazole. After completion of treatment, the lesion completely disappeared and he has been followed up for more than one year in his good condition. The second case showed a single nodule on his right lower lung field and were treated by both medication and surgery. The patient recovered well and had been doing well until 4th postoperative month when he developed humoral rejection and expired.

The compressible flow of reactive fluid is investigated by using the transonic small-disturbance (TSD) model and the one-step first-order Arrhenuis chemical reaction. The fluid flow is restricted to dilute premixed reactions with small heat release. The effects of channel shape and Mach number on transonic combustion are studied by numerical analysis. The results show that the channel divergence increases the chemical reaction within the given channel length whereas the channel convergence inhibits the chemical reaction near the outlet and that increasing the inlet flow Mach number at a fixed reaction rate causes the flow acceleration in a diverging channel and the appearance of weak shock waves which do not show in the inert flow case. It also helps to increase the pressure and temperature near the diverging channel outlet and to consume the reactant within the given channel length.

This study attempted to test the causal effect of structural characteristics of metropolitan neighborhoods on crime, based on the ecological model of crime explanation. To this end, a Negative Binomial Regression analysis was performed for Seoul's 424 Dong Districts. Results showed that the incidence of homicide increases as much as the scales of economic disadvantage, family disruption, and commercial land use go worse. It suggested that family integrity is one of the most strong and consistent factors that could deter crime in neighborhood's contexts. Economic disadvantage and commercial land use were also critical targets as crime-generating factors. Reasoning with the results of past studies implied that neighborhood-specific approaches need to be developed for effective crime prevention. Although a few limitations could raise a caveat against such interpretation of the results, the value of this research would not be simply denied as the first attempt to utilize all Dong districts of Seoul. It is expected that this study contributes to activating Dong level research and developing effective crime control policy.

Men's jewelry are thought to have a limited role as assisting women's jewelry or wedding gifts. The variety of designs are limited, and most of them are just copies of Japanese designs. In order to bring out a new kinds of variety in men's jewelry design, I have chosen architectural structures as a motif. Architectural structures have strong symbolical meanings that express man. They are powerful and challenging, and symbolize wealth and authority. Mario Botta, the wolrd famous architect is an architect with this kind of spirit. His architectural style does not lose his own color in a chaotic situation, but keeps the feeling of shape and space on the basis of locality. In this study I have started with a motif that may express specific and modem feelings by compressing the shape and spatial images of Mario Botta's structures minimally into men's jewelry in order to grope the possibilities in all aspects. I have done these in order to rediscover the beauty of the architectural structures by using the shape and spatial images that are found in Botta's structures, so that I may propose a new kind of men's jewelry with stresses on their shapes.

The purpose of this paper is to improve efficiency in establishing brand identity by researching the effect of local airlines' use of color identity on consumer's brand awareness. Case analysis on color image has first been implemented. And then an empirical study has been carried out in order to measure the effects of consumer's brand awareness based on color image and correlation of an airline company's image with its color image on formation of brand image. Airline's use of color identity, associated with color image, plays an important role in consumer's brand association. Also, the importance of color application will be raised identifying that it has a positive impact in establishing domestic airline's brand identity. This will contribute to the domestic airlines in emerging as global leaders with distinct brand identities and competitive edge. Furthermore, this study will suggest continuing research focusing on new aspects in sensuous consumption behavior given that existing researches on airline's brand have been limited to human services, system, and flight operation.

The purpose of this study is to derive the suggestion of satisfaction of e-book services on the basis of the recent literature on quality assessment for e-service which have been mainly studied on library realm. For this purpose, This study added post-management service which is applicable to measure satisfaction of e-book services based on E-S-Qual and Libqual. We expand our scope of service to using of e-book content and services for individual customers, and analyzed the relationship between satisfaction with the system, the content, the after-sale service. On this foundation, existing e-book service companies can offer their services more efficiently, thereby making the e-book content more diverse, along with developing specialized e-book service to increasing their customer's satisfaction. In addition, the latest and diversity is important as well. Moreover, performing rapid post-management services after the sale of the product or service, can be important variables for customer satisfaction. Therefore, not only the system and content, providing required level post-management services by customers can satisfy the existing customers and create new customers.

Recently, this government is implementing the "eradication of four social evils" policy to root out social evils which includes sexual violence, school violence, domestic violence and substandard food. In retrospect, these social evils are the crimes that have sprung from rapid social changes in Korea. These main four crimes not only badly affect certain victims but also spread their viciousness to broad population. Moreover, the prevention of the occurrence of the crime and the problem solving as an individual unit are hardly possible. Due to their critical effects and continuity, governmental safety policy enforcement is achieving higher support. As an alliance with the calling from the public for happier and safer life, this paper especially focus on regulating substandard food issue, according to the idea that food safety is an essential prerequisite for the healthy and happy life of the people. Through the reviewing, definition of the substandard food will be cleared and specified substandard food crimes will be introduced as well. And the paper will also pose questions in order to propose improved legal measures against the existing regulations, such as newly adding additional penalty article to food sanitation law.

Abandoned empty houses are largely left neglected as unused space, due to the slowdown in the real estate market that has resulted from the declination of urban functions. This research aims to analyze the characteristics of the City of Detroit's policies and regeneration efforts regarding abandoned houses, based on the perspective of unused space. This is expected to provide the baseline data for similar efforts to be applied to abandoned houses in the Korean context, thus preventing the decline of urbanism by adopting relevant policies and regeneration efforts. Some of the key features of the City of Detroit's regeneration efforts are: 1) the active participation of residents and open-data policies, 2) the diversification of regeneration strategies depending on the potential of the unused space, and 3) securing differential plurality of the regeneration processes.
