By taking a bottom-up "library in the life of the user" perspective rather than a top-down "user in the life of the library" perspective, this paper uses anecdotal evidence from the past and near present to examine the multiple roles the U.S. public library plays and has played as public space in the everyday lives of its patrons. By harnessing "public sphere" theory discussed in Jurgen Habermas's THE STRUCTURAL TRANSFORMATION OF THE PUBLIC SPHERE (1989) and by the examining the rich literatures on civic life and institutions that have evolved from it, the author argues that Library and Information Studies discourse has to expand its scope to include research and analysis of "library as place" from a user's perspective if it hopes to develop a deeper understanding of what the public library does for means to members of the communities in which they reside.

Preschoolers are the most effective age to start fire safety education. But, if the education contents are inappropriate, they may form the wrong habit to preschoolers. Many educational contents of fire safety in Korea are not so obvious in the principle and order of priority about what to do during fire and they often contain unnecessary contents to preschoolers such as how to use fire extinguisher. This paper has analyzed fire safety awareness of preschoolers and teachers and, based on the results, has claimed unsuitability of training on how to use fire extinguisher and has suggested the improvement of fire safety education.

Slips and falls are associated with many public injuries in Korea. It is also estimated that slipping are major contributors to slip, trip and fall injury burden. The primary purpose of the present study is to determine if, and to what extent, the standard could be improved in present environment. In order to fulfill our objective, the regulations in Korea and foreign countries were investigated and reviewed. Many kind of standard, mandatory documents and guideline were also reviewed. And then, regulations, standard, guideline etc. reviewed were compared with each others. Also, some criteria was developed in this study. Standard and criteria developed in this study will help to prevent slip, trip, and fall injuries.

Chemical mixtures of components, each of which are present at less than guidance concentrations, may be hazardous due to additivity, interactions, or both. Toxicological interactions may increase the health hazard above what would be expected from an assessment of each component singly, or all components additively. So chemical mixture are a particular issue in public health. There are several approach to assess whether there are additivity or interaction in assessing toxicological effects, such as, components-based approach, physiologically-based pharmacokinetic /pharmacodynamic(PBPK/PD) models, hazard index method, and weight-of evidence method. If we consider interaction or additivity effects in assessing the health effects of chemcial mixtures, we can get more accurate information about toxicological effects and dose-response relationship in chemical mixtures.

Access Control is one of essential branches to provide system's security. Depending on what standards we apply, in general, there are Role-based access control, History-based access control. The first is based on subject's role, The later is based on subject's history. In fact, RBAC has been implemented, we are using it by purchasing some orders through the internet. But, HBAC is so complex that there will occur some errors on the system. This is more and more when HBAC is used with other access controls. So HBAC's formalization and model which are general enough to encompass a range of policies in using more than one access control model within a given system are important. To simplify these, we design the mathematical model called non-access structure. This Non-access structure contains to historical access list. If it is given subjects and objects, we look into subject grouping and object relation, and then we design Non-access structure. Then we can determine the permission based on history without conflict.

The hypertensive encephalopathy is one of sudden convulsive cause in patients with acute post-streptococcal glomerulonephritis, but commonly, after the episode we can observe only mild to moderately hypertension in APSGN at ER. So these remains some question of what causes the convulsion in patients with APSGN. In this article, we report 3 cases of convulsion in APSGN with only moderate hypertension, the etiology of which proved to be due to hypertensive encephalopathy by the brain MRI. We believe that the brain MRI is a very useful test to diagnose the etiology of convulsion in APSGN and if brain edema in occipital lobe is detected by brain MRI, the convulsion would be due to hypertensive encephalopathy and the prognosis will be very good.

In this paper, we propose robot control interface using gaze recognition which is not limited by head motion. Most of the existing gaze recognition methods are working well only if the head is fixed. Furthermore the methods require a correction process per each person. The interface in this paper uses a camera with built-in infrared filter and 2 LED light sources to see what direction the pupils turn to and can send command codes to control the system, thus it doesn't need any correction process per each person. The experimental results showed that the proposed interface can control the system exactly by recognizing user's gaze direction.

The purpose of this study is to evaluate the performances of 5 hospitals which have some different management systems and how are the differences in performance and what do they mean in aspects of architectural planning, if they exist. All of hospitals are located in M city, Jeonnam Province. Data sources are each hospital's patient-statistics and profit & loss statements. Management systems of surveyed hospitals consist in 2 inpatient-based, 1 outpatient-focused and 2 hospitals, not showing any characteristics. Time ranges for survey are 5 years from 1999 through 2003.

Environment friendly architecture, which will reduce shortcomings of current architectural culture, can be achieved by using natural energy and environment friendly building materials together with their environmental architecture techniques. Particularly, even though the overall building system is perfect, it cannot be considered as comfortable architectural space if the materials are polluted, harmful to human bodies and producing wastes. Therefore, in order to build environment friendly architecture, the selection of the materials is very important and necessary from the planning stage with careful reviews and concern. This study tries to define what the environment friendly materials we, to investigate and to classify them, in order to provide some guidelines for selecting them at plans to build. For examples, the materials can be classified into natural materials, continuously usable materials, recycled materials from wastes, and less polluting materials mixed with natural materials. Finally, this study reviews the existing products in the market and proposes to develop new ones in the future. It will present the circulation of resources in the 21century through recycled and reused materials.

Vendor-managed inventory(VMI) is a supply chain strategy to improve the inventory turnover and customer service in supply chain management. Unfortunately, many VMI programs fail because they simply transfer the transactional aspects of placing replenishment orders from customer to vendor. In fact, such VMI programs often degrade supply chain performance because vendors lack capability to plan the VMI operations effectively in an integrated way under the dynamic, complex, and stochastic VMI supply chain environment. This paper presents a decision support system, termed DSSV, for VMI in the retail supply chain. DSSV supports the market forecasting, vendor's production planning, retailer's inventory replenishment planning, vehicle routing, determination of the system operating parameter values, retailer's purchase price decision, and what-if analysis. The potential benefits of DSSV include the provision of guidance, solution, and simulation environment for enterprises to reduce risks for their VMI supply chain operations.
