A reliability analysis is performed to investigate the influence of the uncertainty from few in-situ samples and inherent heterogeneity of the ground on the probability of failure for a rock cut slope. The results are compared with those of deterministic slope stability analysis. The random variables used are unit weight of the rock, the angle of potential slope of failure, and cohesion and internal friction angle of joints. It was found that the rock slope in which the factor of safety satisfied the minimum safety factor in the deterministic analysis has high probability of failure in the reliability analysis when the weak geological strata are involved in the cut slope. The probability of failure of rock slope is most sensitive to the mean and standard deviation of cohesion in rock joint among the random soil parameters included in the reliability analysis. Sensitivities of the mean values are larger than those of standard deviations, which means that accurate estimation of the mean for the in-situ geotechnical properties is important.

The importance of challenging and creative research recently has been increased, risk-taking on the R&D is being needed. The settlement of policy is urgently required in order to protect the result of high-risk research. 'Honorable Failure' is statutory by 'Regulation on the National R&D Program management' to resolve this issue, however its standards and detailed guides are not provided enough or the ministerial funding agencies apply different guidelines, making the researchers on the field confused by far. Therefore this paper reviews the current state of 'Honorable Failure Policy'(saving the 'failed' research despite of its adequate process or performance) and compares with the cases of major countries, then points out following issues; the uncertainty of the criterion, the difference of the main agent performing evaluation, admission of the failure, the utilization of the result of 'failed' research, the vagueness of the range of sanctions and restriction, and the lack of method of inspection and prevention for repetitive failure of the research projects. Finally, this paper proposes the solutions for these issues to improve.

This article reviews the film acting studies of Kracauer presenting the basic approach of traditional film theory. It is to provide a foundation for film acting theory in order to activate the domestic acting studies. While Kracauer explaines the difference between traditional stage actor and film actor in 'Remarks on the Actor' of Theory of Film(1960), he suggests the characteristics of the cinema acting and its media technical meanings. He emphasizes the acting forms presenting the postwar new realism in his film acting studies. His approach takes the perspective of 'physical reality' or 'camera reality' which is the basic premise of film theory. Kracauer insists the naturalness of the actors, listing the features of professional actors, non-professional actors and Hollywood stars as they are a familiar classification for the types of actors. He does not prefer the Hollywood stars, whether it is fiction or documentary, professional or non-professional actors, but he emphasizes negative acting, the ability to express words by doing nothing, based on indeterminacy or indefiniteness of the film. Kracauer's film acting studies has affected later film theory and media-related acting, and has become the principles of cinema textbook and acting.

This study is to explore the development of Korean National Emergency Management System. For the study's purpose, the concept of Emergency, Emergency Management and the existing system and related laws of National Emergency Management have been reviewed. In South Korea, the concept of National Emergency Management contains the variety concept of emergency management; safety management, security management, risk management and disaster management etc. and sometimes using them interchangeably. In addition, there are several laws related to emergency management, making different agencies managing inter-related emergency without nationalized coordination and control tower that results in ineffective management of national emergency. This study attempts to clarify the concept of national emergency and to suggest the necessity of National Integrated Emergency Management System(IEMS). Then, it suggests existing system and related laws's integrate for the development of South Korean National Emergency Management System.

Service part has the attribute causing a difficulty of the systematic management like a kind of diversity, uncertainty of demand, high request for quick response against general complete product. Especially, order picking is recognized as the most important work in the warehouse of the parts since inbound cycle of the service part long but outbound cycle is relatively short. But, increasing work efficiency in the warehouse has a limitation that cycle, frequency and quantity for the outbound request depend on the inherent features of the part. Through this research, not only are the types of the parts classified with the various and specified data but also the method is presented that it minimizes (that) the whole distances of the order picking and store location about both inbound and outbound by developing the model of the demand prediction. Based on this study, I expect that all of the work efficiency and the space utilization will be improved without a change of the inbound and outbound quantity in the warehouse.

This paper deals with an Umbrealla Arch Reinforcement Method (UARM) in tunnelling. It is known that the mechanism of the reinforcement system is too complex to be simulated in existent finite element (FE) frameworks when considering its complex geometry of pipe arrangements and contribution of each component of the reinforcement to reinforcing effect. In this study a 3-D elastoplastic FE procedure is, therefore, proposed by introducing homogenisation technique, which is used to define mathematically elastic as well as elastoplastic characteristics of a reinforced ground material as a composite. A number of practical suggestions are addressed considering staged constructions of tunnels. For illustrative purposes, a series of parametric studies are undertaken and anisotropic characteristics of the reinforced ground as well as effects of the reinforcement on tunnel convergences are investigated. It is found that the reinforced ground material defined in homogenisation framework has its mechanical characteristics reasonably representing inherent geometrical and quantitative characteristics of each of constituents.

The article is to investigate selection of Korean cuisine restaurants and levels of acculturation for foreigner living in Korea and to suggest some guidelines for drawing them and enlargement in consuming market. Out of 250 questionnaires, 220 questionnaires were used for data analysis. The findings are showed visiting for taking experience other culture and learning technology & training, not knowing well much about Korean culture, and eating experience Korean food on 30.5%, less than 2 years length in Korea. And the most difficult points are showed unclear communication, rude behavior, attitude, and language in living Korea. Second, the purpose of visiting restaurant is to spend good time with friends and to eat out special food, then foreigners usually have lunch & dinner Korean food, their own food on weekend. Third, 'service' and 'sanitation & cleanness' factors were ranked highly for foreigners living less than 2 years, but 'location' factor was ranked highly for residents living more than 4 years in the Korea. Last, foreigners living less than 2 years recognized highly on 'identification and Korea culture' in the Korea.

It is necessary to identify the use cases of the supplier systems in order to define new service using their functions. Current use case modeling techniques, however, do not represent the external use cases clearly, because the external system is represented only by an actor. This ambiguity of the modeling technique declines the comprehensiveness of the model, and does not limit the scope of the target system explicitly. In this paper, we propose the extended use case modeling technique for service-oriented computing. This modeling technique enables the definition of external use cases and components. They are used to limit the boundary of the target system, and the relationship between them are modeled by the realization of external use cases. The proposed technique uses UML stereotype extension mechanism. so the compatibility with current use case modeling technique is preserved.

The construction market has gradually become complexity, variety and specialization, and then owner's requirements about quality has become various. In order to solve the problem such as stated above, advanced constructions in France, United Kingdom, Japan and United States have introduced warranty contract which is warranted to quality and performance for need of owner in determined term to ensure the quality of construction since 1960s. In addition to, domestic constructions have been meeting with international competition because of the open BOT market from FTA. Finally, this study proposed new warranty delivery system model in PFI on considering domestic status by benchmarking the delivery process and the characteristics of the warranty contract which is applied to PFI of global.

As software becomes more complicated and large-scaled, user's demands become more varied and his expectation levels about software products are raised. Therefore it is very important that a software engineer analyzes user's requirements precisely and applies it effectively in the development step. This paper presents a requirements analysis system that reduces and revises errors of requirements specifications analysis effectively. As this system measures the similarity among requirements documents and sentences, it assists users in analyzing the dependency among requirements specifications and finding the traceability, redundancy, inconsistency and incompleteness among requirements sentences. It also extracts sentences that contain ambiguous words. Indexing method for the similarity measurement combines sliding window model and dependency structure model. This method can complement each model's weeknesses. This paper verifies the efficiency of similarity measure techniques through experiments and presents a proccess of the requirements specifications analysis using the embodied system.
