  • The purpose of this study is to propose the environmental planning guidelines of elementary school settings for a crime safety. The research methodologies To achieve the goal, the literature review analysis and the survey were used as main research methodologies. The survey is organized as follows. First, elementary education facilities were divided into 20 spaces based on the major space. Second, after analyzing the domestic and foreign CPTED Guidelines, elements of environmental planning were classified to fit in the space. Based on this, the expert survey was conducted. The results of this study are as follows; First, it is necessary to consider specific places such as 'toilets', 'parking lot', 'in-between space', 'main access road', 'sub-access road' and 'harmful facilities around school' for safer school environment. Second, it is significant to plan 'equipment facilities' and 'outdoor space in the school setting' with priority for elementary education environment. Third, environmental planning elements for safer elementary schools can be classified into 9 factors(types) including 'natural surveillance planning', 'territoriality reinforcement planning', 'mechanical surveillance planning', 'access control planning' and 'neighborhood reinforcement planning'. Forth, regarding 'indoor space', crime-free elementary school environment can be build through 'natural surveillance planning' and 'territoriality reinforcement planning'. Finally, regarding 'outdoor space', the crime can be prevented through 'natural surveillance planning' and 'access control planning'.

  • The current study was designed to scientifically evaluate the atmospheric particulate pollution in residences relative to their proximity to a Korean major iron/metal industrial complex (IMIC). This objective was achieved by measuring the concentrations and elemental composition of particulate matter with aerodynamic diameters equal to or less than 10 ${\mu}m$(PM10) in industrial ambient air from IMIC and residential ambient air with relative proximities to IMIC. The trace metals were analyzed using an inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The industrial mean values exceeded the Korean year/70-${\mu}g/m^3$ standard for PM10, whereas the residential mean values did not. However, the maximum residential values did exceed or were close to the Korean PM10 year standard. For individual elements, the ambient concentrations ranged widely from values in the order of a few $ng/m^3$ to thousands of $ng/m^3$. The residential mean mass concentrations in the PM10 measured in the present study were higher than or similar to those reported in earlier studies. This study suggests that residents in neighborhoods near the IMIC are exposedto elevated particulate levels compared to residents living further away from such a source.

  • According to the Korean long-term plan for nuclear technology development, KAERI is conducting a few R&D projects related to the proliferation-resistant back-end fuel cycle. The R&D activities for the back-end fuel cycle are reviewed in this work, especially focusing on the study of the partitioning and transmutation(P&T) of long-lived radionuclides. The P&T study is currently being carried out in order to develop key technologies in the areas of partitioning and transmutation. The partitioning study is based on the development of pyroprocessing such as electrorefining and electrowinning because they can be adopted as proliferation-resistant technologies in the fuel cycle. In this study, various behaviors of the electrodeposition of uranium and rare earth elements in the LiCl-KCl electrorefining system have been examined through fundamental experimental work. As for the transmutation system, KAERI is studying the HYPER (HYbrid Power Extraction Reactor), a kind of subcritical reactor which will be connected with a proton accelerator. Up to now, a conceptual study has been carried out for the major elemental systems of the subcritical reactor such as core, transuranic fuel, long-lived fission product target, and the Pb-Bi cooling system, etc. In order to enhance the transmutation efficiency of the transuranic elements as well as to strengthen the reactor safety, the reactor core was optimized by determining its most suitable subcriticality, the ratio of height/diameter, and by introducing the concepts of optimum core configuration with a transuranic enrichment as well as a scattered reloading of the fuel assemblies.

  • This paper introduces a graphical user interface design that is aimed to apply to the surveillance and security robot, which is the pilot program for the army unmanned light combat vehicle. It is essential to consider the activities of robot users under the changing security environment in order to design the efficient graphical user interface between user and robot to accomplish the designated mission. The proposed design approach firstly identifies the user activities to accomplish the mission in the standardized scenarios of military surveillance and security operation and then develops the hierarchy of the interface elements that are required to execute the tasks in the surveillance and security scenarios. The developed graphical user interface includes input control component, navigation component, information display component, and accordion and verified by the potential users from the various skilled levels with the military background. The assessment said that the newly developed user interface includes all the critical elements to execute the mission and is simpler and more intuitive compared to the legacy interface design that was more focused on the technical and functional information and informative to the system developing engineers rather than field users.

  • Force-deformation modelling of cracked reinforced concrete is essential for a displacement-based seismic assessment of structures and can be achieved by fibre-element analysis of the cross-section of the major lateral resisting elements. The non-linear moment curvature relationship obtained from fibre-element analysis takes into account the significant effects of axial pre-compression and contributions by the longitudinal reinforcement. Whilst some specialised analysis packages possess the capability of incorporating fibre-elements into the modelling (e.g., RESPONSE 2000), implementation of the analysis on EXCEL is illustrated in this paper. The outcome of the analysis is the moment-curvature relationship of the wall cross-section, curvature at yield and at damage control limit states specified by the user. Few software platforms can compete with EXCEL in terms of its transparencies, versatility and familiarity to the computer users. The program has the capability of handling arbitrary cross-sections that are without an axis of symmetry. Application of the program is illustrated with examples of typical cross-sections of structural walls. The calculated limiting curvature for the considered cross-sections were used to construct displacement profiles up the height of the wall for comparison with the seismically induced displacement demand.

  • Generally most of pile foundations are constructed with group pile rather than single pile. The study on efficiency and bearing capacity which are major elements for rational design of this group pile has been actively progressed, whereas there are truly only a few studies of negative skin friction working on group pile due to the consolidation of ground. The purpose of this study is to determine, among the elements of negative skin friction applied to pile, the occurrence modality of negative skin friction at center, side, and corner of $3{\times}3$ group pile using model test and, based on those observations, to propose the effective design direction of group pile.

  • The purpose of this study is to analyze the safety issues with regard to architectural elements in housing. Causes of accidents and threats to health are reviewed for 'safety' aspects. Threats to health tend to draw more attention due to recent increase of SHS and its public perceptions. The majority of victims by accidents in residential houses are on juveniles aged under 14 in bathrooms and living rooms. Non-slip finish materials are recommended to floors for access and circulation and protective pads to furniture edges. Colored glass may increase the safety of the windows in the living room. Handles and non-slip mats will be a good addition for the safety. Human scale design of the kitchen system is mandatory and appropriate size of storages for hazardous equipment are to be provided. Passive air ventilation for better air quality by dwellers in residence is occasionally used whereas large-scale apartments provide mechanical ventilation to supplement the volume of fresh air. Since the internal air quality is proved one of the major causes of atopic and respiratory diseases, steady effort to achive better air quality utilizing appropriate materials, plants and equipment is mandatory. Frequent cleaning and the use of anti-fungus materials are necessary because House Dust Mites are believed to be one of main causes of such diseases.

  • As a building aged, overall performance considering structural safety, equipment safety and fire safety is lowering gradually. Since the building performance and the overall value of the building change as time elapse, exact safety performance of the building should be evaluated not only maintaining the building efficiently and also preventing disputes between buyer and seller of the building. We suggest major elements for assessing building's safety performance through surveying literatures, interviewing experts, reviewing existing assessment models, The assessment elements proposed here ate comprised of structural safety, equipment safety, fire safety, fire protection and fire escape, etc. This study helps to make a safety performance assessment criteria for a building.

  • There has been an increasing and widespread use of smartphones to make consumer purchases. Given the stark increases in the sales of business transactions using mobile phones, it is obvious that mobile phones have become major mediums for consumer purchases. Through mobile phones, people can make their purchases anytime, anywhere, which leads their impulse of consumption directly to actual actions of consumption. Consequently, mobile commerce has become widely spread and the competition of the market has intensified. The main findings and implications of this study are as follows. First, it is shown that, among the features of mobile commerce, elements of fun, usefulness, convenience, immediateness, and security affect mobile commerce user satisfaction. Second, among mobile commerce-related consumers' propensity, innovative consumption tendency appears to impact mobile commerce user satisfaction and repurchase intention. Third, recognition of elements in regards to fun, usefulness, convenience, immediateness, and security among features of mobile commerce affect consumers' intention to repurchase mobile commerce. Future recognition for mobile commerce has a direct impact on increasing consumers' repurchase intentions. Last, a higher mobile commerce user satisfaction leads to the higher repurchase intentions.
