The purpose of this study is to contribute to improvement of educational environment by analysing all problems related to environment around the school. To accomplish this purpose, this study was carried out by examining the problems in controlling the areas required for cleanup with 220 teachers in charging the cleanup duties of the primary and secondary schools in Taegu between June 1 and July 15, 1993 and by actually surveying the prejudical business stores around 72 primary schools between August 10 and September 20, 1993. Although most teachers answered to the questionnaires that it is necessary to cleanup the bad environment around the school, the duties of its cleanup tend not to be considered as an important matter. The teachers considered that the most prejudical business store around the school is totally the game room, and in such order as comic books' store, liquor selling shop and causing noise and pollution. 57.3% of total respondents answered that the present cleanup movements have resulted in failure mostly because of both supervising authorities' careless promotion and store owners' excessive commercial transactions. The result of actual survey in environmental and sanitary cleanup area around 72 primary schools showed that the greatest number of 1,258 prejudical stores was the video tapes shop, and then in such order as lodgings, and game rooms, while the number of prejudical store by the schools was 17.5 stores per school on the average which showed a various distribution from zero to 77 places. In general, these prejudical stores were mainly located around the schools in Jung-gu and Seo-gu areas. In addition, it was shown that the more the number of students, the more the number of the prejudical stores. In order to improve the environment around the school, it is necessary to strictly carry out the zoning system relating to the usage of land, to strongly restrict the stores without permit and abnormal stores and to establish the basis asking the city development authorities to go through the environmental evaluation. Moreover, it is absolutely required to make efforts to establish the national right sense of education, and to closely cooperate with the related authorities.

Since its introduction in the early 1990s, the quick growth of the world Wide Web (WWW) traffic raises the question whether past LAN packet traces still reflect the current situation or whether they have become obsolete. For this study, several LAN packet traces were obtained by monitoring the LAN of a typical academic environment. The tools for monitoring the network were a stand-alone HP LAN Protocol Analyzer as well as the free-ware software tool tcpdump. Our main focus was placed on acquiring a low-level overview of the LAN traffic. Thus, we could determine what protocols were mainly used and how the packet sizes were distributed. In particular, we were interested in establishing the amount of WWW traffic on the LAN, and what MIME-Types this traffic is subdivided into. Our results indicate that in a typical academic environment such as ours, conventional sources of LAN traffic such as NFS are still predominant, whereas WWW traffic plays a rather marginal role. Furthermore, we verified that a large portion of the network packets contains little or no data at all, while another significant portion of the packets has sizes around the MTU. Consequently, research in the networking field has to direct its focus on issues beyond the WWW.

It started road constructions around river in 1990s. These maintenances concentrate on city river. Because river lives no living things and men don't come near there. But in spite of these river environment go to rack, river maintenances still keep on using preexistence method since 1990s. Only a part of city river environment maintenances consider environmental ability of passive river, river maintenance of a purpose of flood control still don't consider in the concrete. Because propulsion device that consider environment ability of passive river and possible application techniques don't complete. In accordance, A natural river maintenance needs absolutly a series of river projects. Because a natural river maintenance prevents a damage of environment ability. This study is to assume the flood really happened and to carry out the flood damage simulation needed in overflow simulation about the inundated zone. Also, This study examine unstable part about the hydraulic characteristic as velocities, stream power, shear, hydraulic depth, flow area in basin. And this study applied the HEC-RAS(river analysis system) model to predict flood overflow in youngsan river basin. Project flood is used the return period 100 year and inputed data that was calculated in intensity figures of illumination.

Augmented Reality(AR) is one of branch of virtual reality computer graphics techiniques that places images of both the real environments and virtual graphic objects over the user's view of the world. Recently, useful apps are being developed using the AR techniques. We developed the location information service app by applying AR techniques. We used the open source 'Mixare' for AR application development for smartphones. This paper presents the design and development of the app 'Go-To-Hongdae~' that shows street views and related detailed information in real-time about buildings around our campus.

Purpose: The aim of this study was to verify psychosocial issues faced by psychiatric and community mental health nurse practitioners (PCMHNP) working in community mental health centers, and to identify the adaptation processes used to resolve the issues. Methods: Data were collected through in-depth interviews between December 2013 and August 2014. Participants were 11 PCMHNP working in community mental health centers. Analysis was done using the grounded theory methodology. The first question was "How did you start working at a community mental health center; what were the difficulties you faced during your employment and how did you resolve them?" Results: The core category was 'regulating within relationships.' The adaptation process was categorized into three sequential stages: 'nesting,' 'hanging around the nest,' and 'settling into the nest.' Various action/interaction strategies were employed in these stages. The adaptation results from using these strategies were 'psychiatric nursing within life' and 'a long way to go.' Conclusion: The results of this study are significant as they aid in understanding the psychosocial adaptation processes of PCMHNP working in community mental health centers, and indicate areas to be addressed in the future in order for PCMHNP to fulfill their professional role in the local community.

This study is about investigation of the historical value of Wanghoido(王會圖) and Bungekipjodo(蕃客入朝圖) and examination of the costumes of the Envoys from the Three Kingdoms drawn in the paintings above. Wanghoido(王會圖) is presumed to be painted around early 7th century. This is a colored picture on silk on which twenty-six Envoys from twenty-four Kingdoms are painted. Bungekipjodo(蕃客入朝圖) is presumed to be painted in the early 10th century. This is drawn on paper with only black brush line, no color. There are thirty-five Envoys from thirty-one Kingdoms in the painting. Wanghoido(王會圖) and Bungekipjodo(蕃客入朝圖) are the important materials which are useful to understand the original Liangjlkgongdo(梁職貢圖). From the records about interchange of the Envoys in the early 6th century, the characters and costumes painted in Wanghoido(王會圖) and Bungekipjodo(蕃客入朝圖), the copy of the original Liangjikgongdo(梁職貢圖), get the reality. The Envoys from Koguryo(高句麗), Paekche(百濟), and Shilla(新羅) painted in the two paintings above are all wearing Jangyu or Yu(장유 or 유; an upper garment), Go(袴:trousers), Kwanmo(冠帽:headdress), Dae(帶뿔:belt), and Hwa(靴:shoes). But they differ in some aspects. For example, the shape of the Kwanmo(冠帽), hair style and patterns on the costumes, etc.

Purpose : The purpose of this study was to determine risk factors and methods in balance assessment associated with fall in older adults. Methods : This article describes many of the tools that can be used to evaluate the physical parameters associated with fall risk in older adults. Results : Composite ratings of performance(Tinetti balance assessment, Guralnik test battery, Berg balance scale, modified-physical performance test) measures the score compounding the balance measure to determine fall risk. Static balance instruments are composed of FICSIT-4 that measures the ability of maintaining foot positions and CTSIB that measures postural stability. Dynamic balance instrument is composed of functional reach test. To measure walking velocity and mobility, 8-foot up-and-go test and walking around two cones are used. We can use 1-RM and to measure muscular strength, isokinetic dynamometery, and 30-second chair stand to measure lower extremity muscle strength. Conclusion : The described instruments are easy to use and widespread. To select and use these tool kits carefully is considered to be helpful in identifying those who are most likely to fall. The final part of the article includes a brief discussion of the potential role of exercise training interventions to improve these physical parameters and prevent falls.

In this paper, we studied the path determination algorithm of the guidance robot for the visually impaired. Using the guidance robot for the visually impaired, the visually impaired can go to the destination where they want without other's heir. The navigation path of the guidance robot for the visually impaired must be the optimal path not only the shortest but also the most safe, which is different from a shortest path for common people. GPS and electronic map are used for the location information of the visually impaired. We corrected the error by converting the coordinates of location information from GPS, which includes maximum several tens of meters error, to the coordinates of electronic map. Information such as simple path and direction to the destination is not enough because it may be different between a going path from the start to the destination and a coming path from the destination to the start as around environment. So, we added information which can be dangerous for the visually impaired such as driveway, sidewalk without braille blocks, crosswalk, stairs and overpass, each has weight value as dangerous degree, when matching the GPS information to the electronic map, enough large as 1:5,000 scale.
