This study is to find out empirically how the fear of crime is affected by the level of recognition of people. CPTED elements including natural surveillance, access control, utilization enhancement, territoriality securement, etc. Safety of residents could be considered and then increased when we plan, design, and operate a city. In Korea, CPTED is currently being applied to every town. However, it is not systemized and neither efficient, for there are no constraint provisions, and the foreign cases are not specifically customized to the current situation of the country. This study, therefore, aims to find the limits from analyzing related laws and regimes, administrative regulations, and applied cases, and to deduct improvement plans based on examined foreign cases.

The main purpose of 1-1-9 Caller Location Information System is to identify and display the precise location of emergency incidents such as natural or man - made fires, medical emergencies and accidents. The state - of- the - art technologies such as Am (Automatic Number Identification), GIS(Geographical Information System) and GPS (Global Positioning System) were applied and integrated in the system for efficient and effective location identification. It displays a radius of 25M, 50M and 100M on the map after location identification. The system can also provide the shortest path to an incident location from a fire station or a fire engine. In case of a fire breakout in or near a building, the attribute information of the building, called a building attribute card, is displayed along with the map location. The system then matches the information with the fire situation and sends an alert to a responsible fire station by phone or fax in order to help promptly react to the problem. An attribute card includes the critical information of a premise such as building's location, number of stories, floor plans, capacity, construction history, indoor fire detection and Prevention facilities, etc.

The purpose of this study is to find out the characteristics of activity areas according to the age difference and provide the alternatives for space planning of activity areas in classroom of childcare centers. This study used the content analysis method for field survey data collected from 36 classrooms of 9 childcare centers in the Daejeon area. Floor plans were converted to Autocad drawings to analyze the characteristics of activity areas. The results of this study were as follows; 1) In case of 0 to 2-year-old classrooms, they had 6 activity areas such as gross-motor area, role play, block building, language, creative expression, exploration/manipulation area. The activity area with the most low frequency was gross-motor area. 2) In case of 0 to 2-year-old classrooms, the size of activity area was in order of gross-motor area > role play > block building > language > creative expression > exploration/manipulation area. In case of 3 to 5-year-old classrooms, the size of activity area was in order of language > art > role play > math > block building > science > tone and rhythmic area. 3) The central areas with easy access in 0 to 2-year-old classrooms were Large-motor and Imaginary Play Areas. Also, more isolated areas were Manupulatives and Block Areas. The central areas with easy access in 3 to 5-year-old classrooms were Arts, Numbers and Manupulatives. While more isolated areas were Music, Movement and Science Areas.

In recent years, Korean population aged 65 and over has grown faster(7.2% in 2000, 14.4% projected in 2018 and 20.0% in 2026) than the other age groups and average life expectancy has increased from 65.8 years in 1980 to 75.9 years in 2000. The Aging Simulation Center(ASC) was built for people to give educational chance for further understanding of the elderly and the environment for the aged. People are able to recognize the changes including hearing loss, vision changes, and changes in the ability to touch and move after experiencing the simulated daily life of older persons. In general, ASC is composed of residential setting area and exhibition area of daily commodities for the elderly and care person. Currently, there are four ASCs in Korea. The purpose of this study is to evaluate the characteristics of space design and design elements of ASCs and to suggest design implementation for better residential environment for the elderly. For the research purpose, design characteristics such as floor plans and spatial design elements of three ASCs were analyzed and compared. As a whole, space design of three ASCs was almost same without distinguished characteristics. The major finding of this study indicates that the ASC is considerably helpful environment to understand aging. However, some of design elements such as lighting should be supplemented for safety issue. It is recommended for future design of ASC to include exterior space including outdoor stairs, paths and roads and so on. In addition, reception and preparation area should be arranged with universally designed furniture.

This study analyzes the common space of the high schools before and after the decade of 2009 which starts Subject-centered clusters school plan, and proposes the direction of common space planning for the future. Based on the floor plans of high schools awarded as excellent school facilities every year, first, types and numbers of common space, second, area ratio between common space and program space and also moving space and staying space, third, space connections were analyzed for tracking the change of the relationship between common, staying and program spaces. The study results demonstrated that types, numbers and area ratio of the common space were increased as the years go on. Especially, the area ratio of staying space was dramatically increased after 2009 and this result was caused by the home-base, alcove space, and hall that were adopted for subject-centered clusters planning after 2009. Connecting diagram of staying area and program spaces also shows the spaces related to staying area were changed from a classrooms and administrative office etc. to a library, gym, and seminar rooms etc. In case of staying area, it would have a value as a common space for various student activities such as group activities, meetings, and multi-uses. Because student activities would be changed and encouraged depending on the location, sizes and program spaces around staying area, it should be emphasized that the planning for staying area is critical for future school design.

The present study purposed to identify differences and similarities in traditional residential space among Korea. China and Japan, which share similar social structure, and to make a comparative analysis on differences in traditional residential space according to family relation in the three countries. For these Purpose, this study selected residences, which are similar to one another in terns of time, class and economy and analyzed them using their floor plans and photographs. The results of this research are as follows. Knrea, China and Japan, all of which have family-centered social structure, separate their residential space from the external society and particularly women's space is placed inside men's space or in a secluded area. The most remarkable characteristic of residential space in Korea is the division of living spare between men and women. Space is allocated according to the hierarchical order of families. In this way, the position or order of family members is reflected in the use of space. Characteristically in China based on the large-family system each family is given a space for independent life. Particularly as the relation among brothers is emphasized, space is allocated equally to all brothers but the status of a space is determined by the order of the residents. Residential space in Japan is organized to emphasize the absolute authority and status of the head of the family. As the space is planned focused on the family head's daily life and guest reception, the relation among other family members is ignored. That is, Japanese residence is a social space for the family head's guest reception, Chinese residence is a family-centered space rather than a social space, and Korean residence accommodates both space for family life and social space.

Constraint directed scheduling techniques, representing problem constraints explicitly and constructing schedules by constrained heuristic search, have been successfully applied to real world scheduling problems that require satisfying a wide variety of constraints. However, there has been little basic research on the representation and optimization of the objective value of a schedule in the constraint directed scheduling literature. In particular, the cost objective is very crucial for enterprise decision making to analyze the effects of alternative business plans not only from operational shop floor scheduling but also through strategic resource planning. This paper aims to explicitly represent and optimize the total cost of a schedule including the tardiness and inventory costs while satisfying non-relaxable constraints such as resource capacity and temporal constraints. Within the cost based scheduling framework, a cost propagation algorithm is presented to update cost information throughout temporal constraints within the same job.

In The process from design to construction in the existing construction work was less efficient due to the contradictory approach of identifying the 3D state in the plan view and the repeated generation of surveys, floor plans, drawings. Accurate 3D design data is essential for smart construction. However, most of the existing related studies have focused on explaining the development method and main functions of equipment or improving the productivity of smart construction. Therefore, in this study, the utility of 3D design model generation for smart construction and construction survey using 3D laser scanner was evaluated. Plane and vertical road alignment were created using the specifications of the road. The generated road alignment was created as a three-dimensional corridor design using cross-sections at intervals of 20m. In addition, it was possible to create a DTM (Digital Terrain Model) using a digital map and effectively create a 3D design model for the study area through overlapping. Construction survey using a 3D laser scanner showed accuracy within 10cm as a result of the accuracy evaluation. These results proved that construction surveying using a 3D laser scanner is possible because it satisfies the acceptable accuracy of the relevant regulations modeling of target areas using 3D design and construction survey using 3D laser scanner can be a way to address shortcomings of existing GNSS (Global Navigation Satellite System) methods. And accurate 3D data will be used as essential data as basic data for smart construction.

The repair and maintenance cost of domestic public rental housing is an issue of considerable interest and growing financial concern. This paper suggests a quantity-based model as an alternative method for predicting costs, instead of the conventional model which is based on actual cost data. Furthermore, this paper provides a forecast of the repair costs incurred each year during the multi family house's maintenance phase (40 years). The recently changed the long-term repair plan and quality-improved interior materials were considered into the research. In order to estimate the cost of maintenance work, 5 sample apartments were selected and analyzed. The repair and maintenance cost from the case studies was converted to cost per household and per floor area for general use. On the other hand, the net present value method was applied to reflect the effect of time. We expect that the results will help to establish expenditure plans that are more effective for public rental housing in the maintenance stage.

The fee-for-service system is used as the main payment system for health care providers in Korea. It has been argued that it can't reflect differences in the medical practice costs across regions because the fee schedule is calculated based on the average cost. So, some researchers and providers have disputed that there is need for adopting geographic practice cost index (GPCI) used in the United States for the Medicare program for the elderly to the fee-for-service payment system. This study performed to identify whether the difference in the practice costs among regions exists or not and to examine the feasibility of applying GPCI to Korea payment system. For this purpose, we calculated modified-GPCI and examined considerations to introduce GPCI in Korea. First we identified available data to calculate GPCI. Second, we made applicable GPCI equations to Korea payment system and computed it based on four types of regions (metropolitan, urban, suburban, and rural). We also categorize the regions based on the availability of the medical resources and the capability of utilizing them. As a result, we found that there wasn't any significant difference in the GPCI by regional types in general, but the indices of rural areas (0.91-0.98) was relatively low compared to the indices of other regions (0.96-1.07). Considering the need to use GPCI floor, the pros and cons of using GPCI, and the concern of the regional imbalance of resources, the introduction of GPCI needs to be carefully considered.
