The number of visitors to historic sites and museums in Korea has been on a rapid decrease and in order to search for creative ways to work on the problem, the study proposed a theme park-typed museum with cultural heritage applied and reviewed spatial strategies for such theme park-typed museums. Applied methods of research of this study are as follows. First, in order to understand definitions and current situations of cultural heritage use and theme park-typed museums, the study went thoroughly over all sorts of literature and reports as well as findings of advance researches on how to make a use of cultural heritage. Based on the results of the investigations, the study determined characteristics of the theme park-typed museums with cultural heritage applied which the study was proposing and the characteristics were categorized by type. Considering those characteristics and types gained in the study, the study looked for cultural heritage-based theme parks and museums in the world which were good enough to be used as research subjects in the study from the aspects of profitability and level of awareness. The study examined those theme parks and museums in the world and in the end, it found out ways to adopt the findings to the situations in Korea and discussed expecting effects as well. As to the characteristics of the theme park-typed museums with cultural heritage applied, the study divided those characteristics into mutual cooperation, location, communicability, authenticity, maintainability, education, durability, narrativity, undailiness, interactivity and leisure. The types were categorized into ride, environment direction, cartoon character and souvenir by attraction pattern. When cultural heritage is used actively, it would improve competitiveness of historic cultural sites and museums in return, making people realize the iterative structure of excavation, conservation, maintenance and use of cultural heritage. That would create many kinds of added values, re-discovering culture of the country. At the same time, it would also create a new value of culture as well. Now, it is important for us to do harder with researches on how to evolve museums and exhibition spaces. Considering that, the study is believed to make a contribution to revival of historic sites and museums in Korea but also establishment of scientific strategies.
A virtual team is defined a group of people that use electronic communications for some or all of their interactions with other team members. Because team members of a virtual team are physically and temporally distributed, a team's transactive memory system(TMS) is considered to be crucial for the team's effectiveness and performance. TMS refers to a set of individual memory systems which integrate knowledge possessed by particular members through a shared awareness of who knows what. This paper seeks to understand (1) how a virtual team's TMS influences team performance, and (2) what factors contribute to developing the team's TMS. Given these purposes, through the extensive literature review, we first identified components and antecedents to develop a theoretical model that predicts a virtual team's performance. Using the survey data gathered from 172 virtual teams, this study found that expertise location, coordination, and cognition-based trust which were proposed as three components of TMS positively influenced a virtual team's performance. Furthermore, this study uncovered that perceived media richness, network tie strength, and shared norms significantly influenced the components of TMS, while geographical dispersion did not exert any significant influence on TMS.
Recently, the use of floating hologram has increased in many different aspects, such as exhibitions, education, advertisements, and so on. Especially, the floating hologram that makes use of half-mirror is widely used. Nevertheless, half-mirror, unfortunately, cannot lead users to the perfect three dimensional hologram experience. Even though it can make the vision look to be up on the air, it does not have the capacity to display itself up on the air, which is the ultimate goal of hologram. In addition, it looks inconsistent when a real object is located behind the half-mirror in order to show the convergence of the two (object and the half-mirror). In this paper, we did the study on comparison of 3D space perception for the stereoscopic AR holography. At first, we applied stereoscopic technology to the half-mirror hologram system for the accurate and realistic AR environment. Then, the users can feel as if the real 3D object behind half-mirror and the reflected virtual image are converged much better in the 3D space. Furthermore, by using depth camera, the location and direction of graphics can be controlled to change depending on the user's point of view. This is the effective way to produce augmented stereoscopic images simply and accurately through half-mirror film without any additional devices. What we saw from the user test were applying 3D images and user interaction leads the users to have 3D spatial awareness and realism more effectively and accurately.
The purpose of this study is to establish trail use impact indicators, and evaluate the degree of use impact based on the understanding of the causality among the impacts on the spot. Theoretical reviews developed three indicators in terms of three ecological impacts, four physical impacts, and five sociological impacts, respectively. With this indicators, observation and questionnaire survey were employed on Gwanak Mountain Trail to measure the levels of impacts forementioned. As for the ecological impact, Some loss of ground cover vegetation was reveled near the trail due to trail use, however the level of disturbance by the naturalized and exotic plants was insignificant. Physical impacts such as soil hardness, enlargement of trail width were found intensified. The result of measuring sociological impacts showed visitors had expected higher level of crowding and encounters before their visit, therefore overall satisfaction level was positive, despite higher awareness level of actual crowding. Intensified continuing use of the trail is aggravating ecological and physical impacts on Gwanak Mountain trail, because of its location in a metropolitan area. Sociological impacts seem favorable at present, however if ecological and physical impacts were deteriorated, sociological impacts would also be affected. To maintain the quality level of use experience, managerial efforts to improve climbing culture as well as ecological and physical environment such as restoration of damaged areas are needed.

This research was completed to provide fundamental data regarding the guidelines to installing and managing utility facilities & structures in wetland protected area to advance the functions and sustainable use of ecology services by preserving the ecology within wetland protected area. There were 5 on-site researching areas that were used as the main subject with these areas chosen and considered from 21 inland wetlands that have been designated and are being managed from the Ministry of Environment and by their designated dates as a wetland protected area. The utility facilities in these wetland areas were categorized by their types and a detailed on-site investigation was proceeded with investigation items chosen whereas these facilities are working by their roles from their location, size, used materials, types, information contents and etc., The results showed that regarding informational structures, several locations of information boards were distanced from the main exploring routes which did not consider the visitor's eye level which had their readability dropped and by sunlight, time lapse and water penetration, many information boards were damaged or corrupted so that it was hard to confirm the information noticed or understanding an image. Insufficient observation and educational structures were installed that considered the ecological characteristics of wild animals and their living conditions. Regarding convenience facilities, there were parking lots that were installed on the fore-land and to decrease non-point solution sources, some parking lots needed to be located in protected lowlands while some facilities' shape and colors did not harmonize with their natural surroundings, creating a sense of awareness, which will need some more consideration. As for safety facilities, they were very insufficient compared to other facilities. This means that additional safety structures are needed so that related personnel can be aware of where a visitor is located when an accident occurs. Protectional facilities strongly needed new structures and a management system to cut off entrances and do surveillance so that visitors do not go into areas outside of the managed areas and bring damages to restricted locations. Research labs needed to expand the use of automatic weather systems and water gauge equipments to build fundamental data regarding floodgates that are intimated to the forming of wetlands. Sensor cameras and other types of monitoring systems are needed to monitor the majority types of animals living in the wetlands as well.

Wedding shops, which had been located in Jung-gu, Jongno-gu, Seodaemun-gu, and Mapo-gu in 1990, have been shown a rapid change in light of location since the year of 1995. Thus, most of shops are concentrated on Gangnam-gu in 2010. Wedding dress shops in Gangnam-gu were distributed between Kanglim Church and Apgujeong station in the early 1990s, and then moved gradually to Dosan park and then to Cheongdam-dong after passing through Hakdong intersection. Luxury image in Cheongdam-dong was the main reason for integration of wedding businesses. This intergration of shops showed the peak at the Cheongdam intersection. A motive of having come to start business in Cheongdam-dong was selected the high awareness and image in district, and was taken the ease for business-based cooperation and connection. High rent and inconvenient transportation were reasons for dissatisfaction. The business-based cooperation and connection were mostly formed through a consulting company. Level and reputation of relevant shops were important elements. Even the connective and associative shops are located the most in Cheongdam-dong followed by Nonhyeon-dong, Shinsa Apgujeong-dong in order. The cluster relationship was most noticeable in wedding studio, wedding dress, wedding consulting, and hanbok(Korean traditional clothes) business. Frequency of vertical cluster was indicated to be more than horizontal cluster. User behavior of wedding businesses in Seoul has been collecting wedding information through internet and wedding consulting business.

Recently, the active research into wireless sensor networks has led to the development of sensor nodes with improved performance, including their mobility and location awareness. One of the most important goals of such sensor networks is to transmit the data generated by mobile sensors nodes. Since these sensor nodes move in the mobile wireless sensor networks (MWSNs), the energy consumption required for them to transmit the sensed data to the fixed sink is increased. In order to solve this problem, the use of mobile sinks to collect the data while moving inside the network is studied herein. The important issues are the mobility and energy consumption in MWSNs. Because of the sensor nodes' limited energy, their energy consumption for data transmission affects the lifetime of the network. In this paper, a mobile-sink based energy-efficient clustering scheme is proposed for use in mobile wireless sensor networks (MECMs). The proposed scheme improves the energy efficiency when selecting a new cluster head according to the mobility of the mobile sensor nodes. In order to take into consideration the mobility problem, this method divides the entire network into several cluster groups based on mobile sinks, thereby decreasing the overall energy consumption. Through both analysis and simulation, it was shown that the proposed MECM is better than previous clustering methods in mobile sensor networks from the viewpoint of the network energy efficiency.

This paper suggest a way to detect a specific wanted figure in public places such as subway stations and banks by comparing color face images extracted from the real time CCTV with the face images of designated specific figures. Assuming that the characteristic of the surveillance camera allows the face information in screens to change arbitrarily and to contain information on numerous faces, the accurate detection of the face area was focused. To solve this problem, the normalization work using subsampling with $20{\times}20$ pixels on arbitrary face images, which is based on the Perceptron Neural Network model suggested by R. Rosenblatt, created the effect of recogning the whole face. The optimal linear filter and the histogram shaper technique were employed to minimize the outside interference such as lightings and light. The addition operation of the egg-shaped masks was added to the pre-treatment process to minimize unnecessary work. The images finished with the pre-treatment process were divided into three reception fields and the information on the specific location of eyes, nose, and mouths was determined through the neural network. Furthermore, the precision of results was improved by constructing the three single-set network system with different initial values in a row.
The purpose of this study was to investigate early childhood special education teachers' experience, difficulties and need for effective disability understanding education in inclusive education field. The researcher interviewed 3 different early childhood special education teacher. Each participant was individually interviewed 2-3 times with deliberated questions for collecting data. After the interview was analyzed, the contents were categorized into three major themes and twelve sub themes. The three major themes were (1) early childhood special education teachers' difficulties in inclusive education field. (2) experience in the disability understanding education (3) need for proper disability understanding education. First, the teachers were awareness of the difficulties at the inclusive education field due to ambiguity in the role and location, the extension of the expertise, and the misaligned system. Second, teachers stated that the barriers to disability understanding education include creating prejudice, varied according to teachers ' abilities, poor perception of appropriate methods, and low concerns of adults and young children. Third, the results showed that development of the teaching manual, improvement of the administrative system, change in perception of disability understanding education, and disability understanding education based on the experiences of young children were necessary for effective disability understanding education. Based on these results, several specific implications for effective disability understanding education were suggested.
Background: The objective of this study was to determine the practice of skin cancer prevention among Malaysian road traffic police officers. Materials and Methods: This cross-sectional study involved 202 Malaysian Road Police Traffic officers. Inclusion criteria were those officers who work wearing white uniform regulating traffic. The survey took place at the Police Traffic Station, Jln Tun H.S. Lee, Kuala Lumpur, the main Head Quarters of Malaysian's Traffic Department where almost 600 police traffic officers are employed. The police traffic officers are given the task to take care of the traffic from the main office of the police station, then, according to the task, the officers drive to their given location for their duty. Each task is approved by the Chief Traffic Inspector of Kuala Lumpur. Data collected in this study were analyzed using SPSS 13, with the T-test for univariate analysis and multiple linear regression for multivariate analysis. Results: A total of 202 road traffic police officers participated. The majority were older than 30 years of age, male, Malay, married, with secondary education, with monthly income more than 2000 Ringgit Malaysia (66.3%, 91.1%, 86.6%, 84.7%, 96%, 66.3%; respectively). Regarding the practice of skin cancer prevention, 84.6% of the study participants were found to wear hats, 68.9% sunglasses and 85.6% clothing that covering most of the body but only 16.9% used a sunscreen when they were outdoors. When analysis of the factors that influenced the practice of skin cancer prevention was performed, univariate analysis revealed that gender, age and monthly income significantly influenced the practice of skin cancer prevention. For multivariate analysis, gender, monthly income and race significantly influenced the practice of using sunscreen among road traffic police officers (p<0.001, p=0.019, p=0.027; respectively). Conclusions: The practice of skin cancer prevention among the traffic police officers showed good practices in terms of wearinga hat, sun glasses and clothing that covers most of the body. However, the study revealed a poor practice of the use of sunscreen. The factors that influence the practice of sunscreen use were found to be gender, income, and race. The study suggests that more awareness campaign among traffic police officers is needed. Providing sunscreen for free for police traffic officers should be considered by the Police authorities.
