Climate change has impacts on not only the average temperature rise but also the intensity and frequency of extreme events such as flood and drought. It is also expected that the damages on agricultural infrastructure will be increased resulting from increased rainfall intensity and frequency caused by climate change. To strengthen the climate change adaptation capacity, it is necessary to identify the vulnerability of a given society's physical infrastructures and to develop appropriate adaptation strategies with infrastructure management because generally facilities related to human settlements are vulnerable to climate changes and establishing an adaptive public infrastructure would reduce the damages and the repair cost. Therefore, development of mitigation strategies for agricultural infrastructure against climatic hazard is very important, but there are few studies on agricultural infrastructure vulnerability assessment and adaptation strategies. The concept of vulnerability, however, is difficult to functionally define due to the fact that vulnerability itself includes many aspects (biological, socioeconomic, etc.) in various sectors. As such, much research on vulnerability has used indicators which are useful for standardization and aggregation. In this study, for the vulnerability assessment for agricultural infrastructure, 3 categories of climate exposure, sensitivity, and adaptation capacity were defined which are composed of 16 sub-categories and 49 proxy variables. Database for each proxy variables was established based on local administrative province. Future studies are required to define the weighting factor and standardization method to calculate the vulnerability indicator for agricultural infrastructure against climate change.

Tunnel lighting design and operation are both regulated based on luminance in and out of Korea these days. However, domestic tunnel lighting is operated by internal lighting depending on external brightness by using an illuminometer applying the conversion factor on luminance. The purpose of tunnel lighting is to alleviate the visual shock occurring from the rapid change from external brightness to internal brightness when entering a tunnel. However, when looking at the tunnels operated based on an illuminometer, it is not a system where the driver can measure the brightness within his or her viewing angle when entering the tunnel. It is general to install and operate the illuminometer on the roof of an administrative office near the tunnel; however, this method is not structured to connect with the internal lighting by checking the brightness of the viewing scope of the driver, thus is not structured to properly apply the viewing conditions of the driver. Rather, it should be in a method for extracting the luminance value within the viewing scope of the driver pursuant to tunnel lighting standards and in connection with internal lighting. This research seeks to find the difference between operations based on luminance and operations based on intensity of Illuminance in road tunnels through field measuring, and to suggest the necessity of operating based on luminance with the resulting value.

For the quality of life and independent living of the disabled, government has provided financial supports for housing renovation and improvement projects for the disabled. However, there is a limited budget which should be properly distributed for a number of disabled families. Therefore, it is important to decide which parts should be improved for housing renovation for the disabled. Financial and administrative supports for the renovation should improve housing conditions in terms of accessibility (barrier free) and should bring the better comfort for the disabled. The purpose of this study was to describe the characteristics of the housing renovation projects, to investigate whether the renovation influence occupants' satisfaction, and to examine which factor such as renovation cost and renovation elements would influence the degree of satisfaction for residents with disabilities. Participants of this study are limited to the recipients of financial supports for housing renovation and refurbishment from City of Seoul and Ministry of Health and Welfare. A total of 153 cases were analyzed using post occupancy survey and the project cost data for the participants' housing were collected. Overall, more cost were used for modification for housing condition than for removal of architectural barriers. Housing type and physical condition of the housing affects cost for renovation more significantly. Overall the improvement cost is positively related to resident's satisfaction using regression analysis. In addition, it is important to meet the residents specific needs for repair, refurbishment, and renovation of housing.

According to the development of information system, many information system and application soft-ware are develop. However, cyber attack and incident have more increased to the development of them. To defend from cyber attack and incident, many organizations has run information security systems, such as Intrusion Detection System, Firewall, VPN etc, and employed information Security person till now But they have many difficulty in operating these information security component because of the lack of organizational management and analysis of each role. In this paper, We propose the formal Cause-Effect Model related with the information security system and administrative mission per each security. In this model, we regard information system and information system operator as one information component. It is possible to compose the most suitable information component, such as information system, human resource etc., according to the analysis of Cause-Effect Model in this paper. These analysis and approaching methodology can make effective operation of each limited resource in organization and effective defense mechanism against many malicious cyber attack and incident.

The purposes of this study were to compare, through a factor analysis, the perceived level of importance of 4 categories of features relating to food service management between salespeople and clients, to establish an effective marketing strategy for successful contracting. To obtain data on the perceived level of importance level of the factors affecting foodservice management contracts, questionnaires were developed using the Delphi technique, which were modified by apilot test. The questionnaires consisted of 4 categories and 19 items on the factors affecting foodservice management contracts, with the importance level of these factors measured on a 5 point-Likert type scale. Between March 12 and April 13 2003, the self-administrative questionnaires were mailed to the 60 salespeople and 280 clients. A total of 50 clients (25%) and 48 salespeople(77%) responded to the questionnaires. As a result, forprivate contracts and in competitive biding, the differences of the perceived importance level between the salespeople and clients of the 3 categories (the appropriateness of foodservice operation plan, sales ability, the conditions and costs of the contract) were significant. For the 5 items relating to private contracts, Field trip, Menu Management Plan, Sanitation and Safety Management, Cost per meal and Food Cost per meal, both the salespeople and clients perceived high levels of importance for all these items. For competitive biding, both the salespeople and clients perceived high levels of importance for the 6 item the Foodservice operation supportive system, Field trip, Menu Management Plan, Renewal plans for interior and environment, Cost per meal and Food Cost per meal.

For housing estate of a new administrative capital city, Noise reduction method is a important design factor. As measuring a noise level of traffic noise according to separation from road, it can be created a quite housing estate. Analyzing of merits and demerits in sound barrier walls and tunnels can be proposed environment friendly soundproofing facilities. Number of measurement was performed to know what kind of layout of housing estate is good for noise reduction. Through this measurement, ㄷ shaped layout or parallel layout has the advantage of sound insulation rather than right angled layout. In this case (ㄷ shaped layout or parallel layout) buildings neighboring to the road should be designed to insulate sound. Evergreen trees should be planted between housing estate and road more than 30m (at least 7～8m) in order to reduce noise and have masking effects. If broad-leaved trees are planted more than 30m, approximately 10dB noise is reduced and 2～4dB if 7～8m. Roads in the estate should be designed considering pedestrians first, and special roads for moving and ambulance should be designed as skew road, if possible. The result shows that 15$^{\circ}$-sloped‘S’road reduces 1～2dB noise and 30$^{\circ}$-sloped road reduces 4～7dB. If noise barrier is inevitably installed, it should be designed to go well wit neighboring environment so as to install Environment Friendly Noise Barrier using materials and trees including wood and soil. Through this study the results are used to guideline for construction of environment friendly housing estate

The more mobile technology evolves, the more users are trapped in mobile technology by being encouraging the replacement with state-of-the-art technology. However, the use of device is not entirely determined by technology's attributes itself. The meaning of smartness can be varied by 'how users accept and perceive immediate spatial perception from reality to mobile space' without recognizing the boundaries between them. This study focuses on the analysis of 'smart usage' for smartphone and this is verified the concept of 'smart usage' by the second-order measurement model. The result show that the concept organization of 'smart usage' had been differentiated and elicited by the six factors - 'multifunctional use readiness', 'administrative efficiency', 'embedded media', 'device connectivity', 'user-friendly optimization', and 'external connectivity(being connected). According to the conceptual factors, 'smart usage' can be explained in an individual's autonomous ability to control a mobile interface and to utilize a wide range of applications of smartphones.

Violent crimes have increased continuously due to the development of urban society and have become a threatening factor against the residential safety of citizens. The prevention of these crimes is always a major topic in human society and one of the fundamental elements of the quality of life and safety of citizens. In recent years, much attention has been paid to environmental design through the Crime Prevention Through Environmental Design (CPTED) as a preventive measure. Currently, South Korea is promoting the openness and utilization of public data, and crime prevention is one of the fields that can utilize public data actively. This approach to crime prevention utilizing public data will be helpful for the proposal of policies from new viewpoints departing from the general utilization measures of CPTED that improve streetlights and closed-circuit television (CCTV) installations, whose limitations have been pointed out as they are only mechanical surveillance. Thus, this study sets the research scope based on the statistics of the status of five criminal offenses by administrative district in recent years provided by the data portal in Seoul City, the capital of South Korea, as the utilization data and concentrates on the analysis. Based on the analysis results, this study proposes a method to utilize classical music as a new policy for regions where the improvements are most needed. The open-source Python analysis program was employed as the main data analysis and visualization method.

This study examined the effects of teacher job stress and emotional intelligence on the turnover intent and job satisfaction. To this end, an early childhood teacher survey of 220 people using SPSS 9.0 data processing, analysis, and the independent variables were used to predict the dependent variable. Simple regression analysis and regression analysis of a follow-up examination were then performed. In the first study, the early childhood teachers' turnover intention due to job stress and job satisfaction revealed job stress to be a significant factor. The children's lack of leadership and administrative support work overload factors contributed to causes of stress. The turnover intention appeared to affect the mind. Second, early childhood teachers job satisfaction, job stress and turnover intention were affected by attempts to mediate the influence of job stress. Therefore, mediation plays a significant role. These results show that infant teacher duties affect the turnover intention and job satisfaction.
