Recently electronic journal articles prevail throughout researchers because of the development of internet and electronic publishing technology. It is caused by limited collection development budget, lack of physical storage space for printed journals in libraries, and the user convenience of web services. But from the view of ownership, electronic journals can be unfavorable to information users or libraries who cannot have the permanent right to access all the subscribed journals. Actually the libraries only have right to access journals for subscription periods in using electronic journals. So the users and libraries are willing to purchase printed journals in spite of high cost. As an basis for collaborative collection development and sharing preservation of Korean libraries for the foreign journals, the data analysis is carried out for the journals collection in terms of regional distribution, overlapping status, and journal subject. And the considerables are discussed for collaborative strategic collection development, which means the reduction of overlapped subscription and maximization of utilization in a national standpoint.

This research aims to introduce the theoretical basis of the studies of tourism resources, by review the research trends of tourism resources in the geography field. The geographical approaches to tourism resouces can be subdicided into 3 categories according to the subject. First, the classification of tourism resource types and the approach on the spatial distribution may be enumerated. This subject has been the object of the most interest and discussion to the geographers for tourism up to now. And from the viewpoint of contents, it has been developed by classifying the types of tourism resoures, which is based on the establishment of the range and standard of tourism resources and the spatial classification of types based on the distribution feature of the area. Second, the approach about cognition, preference and interpretation on the tourism resources as the background to induce tourism phenomenon and decide the tourism destination. Judging from the fact that most of this subject is starting from the behavioural study and that the right understanding and interpretation of tourism resource is the important factor to decide the preference degree of tourists, we have to have much interest about the field of tourism geoaraphy. Third, the development of tourism resources which is showing the active study recently and its influence and effect attendant upon it may be enumerated. Today, as the economic value of tourism is become important internationally, tourism resources are recognized as the important factor to induce the industrialization of tourism. And in the series of analytical studies related to it the interest has been transferred from the economic benefit analysis attendant upon tourism development including tourism resource and to the cultural, educational, environmental and psychological influence, etc. As the result of composite examination, for the geographical studies about tourism resources, the spatial scale and the contents are being subdivided and specialized. And in the side of subject and method of study, it is developing into the positive study based on the concrete data and the measuring and analytical frame.

This study explores an initial framework for online product categorization by examining the relationships among Internet motivations, buying tendencies, and online purchase intentions for product categories. A total of 217 usable questionnaires were obtained from respondents in a southwestern state in the United States. A path model using a correlation matrix with maximum likelihood was estimated using LISREL 8.53. Findings indicated that Internet motivations consisted of four factors: Diversion, Economic, Information, and Social motivations. In addition, online products were classified into three categories based on purchase intentions: Sensory, Cognitive, and Search products. Estimated path model showed that diversion and economic motivations affected impulse buying tendency, whereas economic, information and social motivations influenced planned buying tendency in the online context. Also, the buying tendencies were significantly related to online purchase intentions for the product categories. Purchase intentions for sensory products were more strongly affected by impulse buying tendency, whereas purchase intentions for cognitive and search products were more strongly affected by planned buying tendency. Theoretical and managerial implications were discussed for devising an appropriate e-market strategy for specific product categories.

The im of the present study is to introduce and develop the concept and theory of conspectus for the first time in Korea, and to propose a new evaluation model for book collection by actually applying the developed methodology to the collection of a special library dedicated to Biblical Studies. Conspectus is a standardized and objective evaluation method that classifies the main collection according to the division, category, subject, and then gives each collection ots appropriate collection level code by analyzing the classified collection in terms of three different dimensions, which are Current Collection Level(CL), Acquisition Commitment Level(AC), and Collection Goal Level(GL). To evaluate the collection of the sample library, shelflist analysis, list checking, acquisition data in ordering process by their main subject, and survey of its users have been carried out, and all of their results ahve been indicated in terms of eleven collection level codes developed by WLN Conspectus. T e collection of sample library was evaluated as '3cW' for CL, '4W' for AC, and '4W' for GL when the Conspectus methodology was applied for evaluation. This study could be utilized as an collection evaluation model for theological libraries, and become a basis to bring about more active cooperative collection development among related libraries.

The smectite-illite (SI) reaction is a ubiquitous process in siliciclastic sedimentary environments. For the last 4 decades the importance of smectite to illite (S-I) reaction was described in research papers and reports, as the degree of the (S-I) reaction, termed "smectite illitization", is linked to the exploration of hydrocarbons, and geochemical/petrophysical indicators. The S-I transformation has been thought that the reaction, explained either by layer-by-layer mechanism in the solid state or dissolution/reprecipitation process, was entirely abiotic and to require burial, heat, and time to proceed, however few studies have taken into account the bacterial activity. Recent laboratory studies showed evidence suggesting that the structural ferric iron (Fe(III)) in clay minerals can be reduced by microbial activity and the role of microorganisms is to link organic matter oxidation to metal reduction, resulting in the S-I transformation. In abiotic systems, elevated temperatures are typically used in laboratory experiments to accelerate the smectite to illite reaction in order to compensate for a long geological time in nature. However, in biotic systems, bacteria may catalyze the reaction and elevated temperature or prolonged time may not be necessary. Despite the important role of microbe in S-I reaction, factors that control the reaction mechanism are not clearly addressed yet. This paper, therefore, overviews the current status of microbially mediated smectite-to-illite reaction studies and characterization techniques.

Due to spatial problems and system size,conventional measurement methods used to acquire the information needed for existing electrical energy and management have been limited to new buildings or areas where replacement is possible. This electric load management method is problematic when applying it to energy and safety management of vulnerable areas or existing homes or offices. The problem with installing a measurement module in every branch is that the system is too large. Even if the measurement module is installed, the type of load is not recognized, and efficient management is not performed. In particular, it is very difficult to apply it to traditional markets and backward facilities in Korea. In this paper, we apply NIALM technology and arc detection technology to solve these problems and verify the feasibility of NIALM for normal arc generation. Also, based on the verification results, we propose a new smart home safety management system that can effectively manage electrical safety and that can be applied to conventional market and existing home safety management systems. The proposed system conducts a comparative performance test with an existing safety management system. In addition, it achieves 95% or more load recognition for four loads, which is impossible in 40% of the existing systems, and the arc detection function was confirmed.

This study targets to recognize needs of adopting public management system in Urban Renewal Project. and to establish evaluation level of public management system using policy evaluation framework for establishing perspective and systemic level. Also, this study constructed basic principles as expanded concept like Public, expertise, participation, rationality, and sustainability based on previous studies and expert opinion. AHP analysis results are following. In case of upper level, post management and continuity are important factors. Also in case of under level, making stable economic system, honest operating system, reducing development costs, local development with self-sufficiency were important factors. through empirical results, the implications are following. First, public management system needs to develop a consistent principle from planning step to post management. Second, it is essential point that continuous retraining between involved people and drawing residents participate in progress activity. Third, when evaluating public management system, it is need that emphasize non-physical factor like conflict issue between stakeholder.

The Campus Core is centered at the physical, functional and symbolic environment of a university, which is known as the top academic institution, hence it metaphorically represents not only the educational philosophy when institution first opened, but also the transformed values of the time. Today, universities are asked to actively communicate with the local community in terms of function and be remodeled as pedestrian-friendly campuses in terms of physical environment. For this reason, the study comprehends the concept of the campus core in accordance with a pedestrian-friendly environment and suggests a practical plan for campus cores of district national universities based on previous research examination. Since the purpose of the study is to suggest a change in the circulation system centered on vehicle use to transform into a pedestrian-friendly environment through a planned approach while introducing public mixed-use at the same time, the study supports the fact that it is possible to reorganize the strategy of a pedestrian-friendly circulation system and partially revise the land utilization to yield the expected outcomes. Thus, this study will provide valid suggestions for similar maintenance plans while looking back to the meaning and value of today's campus core.

The secret sharing is the basic concept of the threshold cryptosystem and has an important position in the modern cryptography. At 1995, Jarecki proposed the proactive secret sharing to be a solution of existing the mobile adversary and also proposed the share renewal scheme for (k, n) threshold scheme. For n participants in the protocol, his method needs O($n^2$) modular exponentiation per one participant. It is very high computational cost and is not fit for the scalable cryptosystem. In this paper, we propose the efficient share renewal scheme that need only O(n) modular exponentiation per participant. And we prove our scheme is secure if less that ${\frac}\frac{1}{2}n-1$ adversaries exist and they static adversary.

The purpose of this study is to expand a prospect of a few-remaining Byeolseo scenic sites of Gangwon-do(Province) through determining placeness formation, prospect characteristics, and landscape meanings of Gumi(Nine beauties) and Sipalgyung(18 scenic views) in Gumijeongsa. Gumijeongsa, which is located in a riverside of the Goljicheon(stream), a part of upstream of Namhangang, is the oldest existing Nujung architecture in the Jeongseon area. This study tried to unearth the Gumijonegsa's locational and formational characteristics through literature review and a field survey. Especially, through the field survey, this study tried to figure out the landscape meanings and contents of Gumi and Sipalgyung by Gumijeongsa's position and its prospect compositions. As a result of this study, Gumi and Sipalgyung of Gumijeongsa are variations of typical traditional culture of Gugok(Nine river bends) and Palgyung(Eight scenic views). Ja Lee, the founder, administrated Gumijeongsa as a core residence of Gugok culture. He established beautiful nine viewpoints from the building, named Gumi, and added 18 detailed landscapes(two landscapes for one beauties), instead of establishing nine river bends of the stream. The Gumi and Sipalgyung are formed by reflection of beautiful locational characteristics from the views in Gumijeongsa, thus the Gumi is the concept which is a unique variation of Gugok and Palgyung culture.
