As the "Guidelines for GHG Environmental Assessment" was revised, it pointed out that the developers should evaluate GHG sequestration and storage of the developing site. However, the current guidelines only taking into account the quantitative reduction lost within the development site, and did not consider the qualitative decrease in the carbon sequestration capacity of forest edge produced by developments. In order to assess the quantitative and qualitative effects of vegetation carbon uptake, the CASA-NPP model and satellite image spatial-temporal fusion were used to estimate the annual net primary production in 2005 and 2015. The development projects between 2006 and 2014 were examined for evaluate quantitative changes in development site and qualitative changes in surroundings by development types. The RMSE value of the satellite image fusion results is less than 0.1 and approaches 0, and the correlation coefficient is more than 0.6, which shows relatively high prediction accuracy. The NPP estimation results range from 0 to $1335.53g\;C/m^2$ year before development and from 0 to $1333.77g\;C/m^2$ year after development. As a result of analyzing NPP reduction amount within the development area by type of forest development, the difference is not significant by type of development but it shows the lowest change in the sports facilities development. It was also found that the vegetation was most affected by the edge vegetation of industrial development. This suggests that the industrial development causes additional development in the surrounding area and indirectly influences the carbon sequestration function of edge vegetaion due to the increase of the edge and influx of disturbed species. The NPP calculation method and results presented in this study can be applied to quantitative and qualitative impact assessment of before and after development, and it can be applied to policies related to greenhouse gas in environmental impact assessment.

We use a scale mainly for quantification when we study the psychological characteristics that we cannot observe. The utilization of a scale is frequent in scientific educational studies. The convenience offered by Likert scale, which is among the most frequently used, enable us to grasp characteristic attitude or recognition in students, and evaluate them against an affective domain. But a lot of errors occur, and has been noted as well in the case of utilizing Likert scale in the process. A central tendency in the utilization of Likert scale appears in this study, and the trend analyzes according to study objects and study contents, but we intend to find a way to utilize Likert scale. The results of study made on our countryside students show that the answers tend to get concentrated and a central tendency appears. Our countryside students were aware of the eyes surroundings them, have respect for elders through social experiences, and have had troubles with differentiated expression or personality in the group and cultural environments. According to the object of study, the central tendency appears more among older students than younger students, more among general students than gifted students. In the contents of study, the central tendency has been given more appearance in scope and their exposure has relatively been in large domain. Therefore when utilizing Likert scale in scientific education study, an error of central tendency appears as if they are results of the study. So, when applying the Likert scale to scientific study, we need to consider sociocultural environment, characteristics of an object and contexts of study. This enables avoiding dependence on numerical value of the utilization results, and interpret them correctly.

The conventional design of the information system architecture based on the personal experience of information systems has been acted as a limit in progress utilizing appropriate resource allocation and performance improvements. Architecture design depending on personal experience makes differences in variance of a designer's experience, intellectual level in related tasks and surroundings, and architecture quality according to individual's propensity. After all these problems cause a waste of expensive hardware resources. At working place, post-monitoring tools are diversely developed and are running to find the bottleneck and the process problems in the information operation. However, there are no simulation tools or models that are used for expecting and counteracting the problems at early period of designing architecture. To solve these problems we will first develop a simulation model for designing information system architecture in a pilot form, and will verify validity. If an error rate is found in the permissible range, then it can be said that the simulation reflects the characteristic of information system architecture. After the model is developed in a level that can be used in various ways, more accurate performance computation will be able to do, getting out of the old way relying on calculations, and prevent the existence of idle resources and expense waste that comes from the wrong design of architecture.

Purpose: The aim of study was to estimate the hand hygiene (HH) compliance of healthcare workers (HCWs) in a children's hospital. Methods: This study was conducted in a hospital which is a tertiary and educational children's hospital with 313 beds and 533 HCWs. Data were collected by direct observation methods from November 1, 2010 to December 31, 2010. Results: A total of 2,999 opportunities for HH were observed, and the overall HH rate was 95.3%. HH rate of the registered nurse, physicians and transferer was 97.7%, 89.2%, and 72.1%, respectively (P<0.001). Among physicians, HH rate of the fellows, professors, residents and interns was 97.5%, 93.9%, 89.7%, and 80.9%, respectively (P<0.001). HH rate in the emergency room, operation room, outpatient department (OPD), and the intensive care unit (ICU) was 97.2%, 97.2%, 95.4%, and 92.5%, respectively (P<0.001). Hand rubbing was the most frequently used (81.1%), and hand washing was frequently used in the case of 'after body fluids exposure risk' (37.7%) and 'after touching patient surroundings' (28.5%). HH methods were not statistically different from each departments (P =0.083), however, they were significantly different according to the World Health Organization (WHO) 5 Moments (P<0.001). Distributions in WHO 5 Moments by the job titles were significantly different (P<0.001). The odds ratio of physicians, ICU and OPD was 0.353 (95% CI, 0.241-0.519), 0.291 (95% CI, 0.174-0.487), and 0.484 (95% CI, 0.281-0.834), respectively. Conclusions: Compliance of HH was different by the job titles and departments. Effective custom-tailored HH programs for each job title and department need to be developed.

To investigate the prevalence of Staphylococcus aureus (S. aureus) during production of perilla leaves, a total of 261 samples, including water, soil, surroundings of cultivation and packing, workers, and perilla leaves, was examined.. To trace the contamination sources of S. aureus related to perilla leaves, MLVA (Multi-Locous Variable number of tandem repeat Analysis), which is a very efficient method to discriminate strains with minimum molecular biology equipment was applied to S. aureus isolated from perilla leaves farms. S. aureus was isolated in perilla leaves from 9 of 38 farms at 0-2.92 log CFU/g. S. aureus was also found in working environment, including packing vinyl, worker clothes, irrigation water and hands. The patterns of MLVA of isolates from perilla leaves matched with those of isolates from packing table, irrigation water, packing vinyl, and hands. The isolates were successfully examined and determined by MLVA, thus elucidating S. aureus source and spread.

This study examined the meanings of the disability education of the mothers who reared their children with brain lesions. For this purpose, Rennie's hermeneutic grounded theory was applied and the consented 7 mothers participated in this study. With the in-depth interviews, 53 meaning units, 16 subordinate categories and 7 hermeneutic categories were classified. These 7 hermeneutic categories were 'wailing miserably everyday', 'social mobilization of the surroundings', 'straight forward', 'smash rock with the eggs', 'looking at a faraway', 'learning together' and 'subjectivation of disability education.' The experience of disabled children education process was concurrent experience of frustration and hoping that moving toward a big hope through the resignation stage, the chasing stage, the vision stage, the challenge stage, and the small achievement stage. Repetitive common patterns of behavior revealed three types: wishy-washy type, realistic-strategy type, and indomitable-challenge type. Moreover, the core category of educational experience was concluded to be 'a pedagogical process of turning despair from severe disabilities into hope through education.' Based on the analysis results, concrete intervention plans for social welfare practice were suggested to support the disabled children's lives with high quality of education.

Chungnam Basin has been known as one of the largest Mesozoic basins in Korea, filled mainly with so-called Daedong Supergroup. The basin has evolved as the Early to Middle Jurassic intra-arc volcano-sedimentary basin developed on top of the Late Triassic to Early Jurassic post-collisional basin in this area, recording evolutionary history of the Mesozoic tectonics in the southwestern Korean Peninsula. This study carries out the geometric interpretations of the Seongjuri syncline and its surroundings in the central part of the Chungnam Basin, based on detailed structural field survey. Based on its doubly-plunging fold geometry, the Seongjuri syncline could be subdivided into the southwestern and northeastern domains. On the down-plunge profiles of the southwestern domain of the Seongjuri syncline as well as the underlying Okma fold, the Okma fault shows typical geometry of a basement-involved reverse fault that propagated up to the sedimentary cover. The profiles illustrate that the Seongjuri syncline occurs in front of the tip of the Okma fault, likely implying its origin as a part of the fault-related fold system. The result of this study will provide better insight into the structural interpretation of the Chungnam Basin, and will further provide useful information for the Mesozoic orgenic events of the southwestern Korean Peninsula.

The purposes of this study are to analyze the spatial composition of the outer garden of Soswaewon that appears in Gyeong-Ji Yang's "30 Poems of Soswaewon" and examine its significance and symbols. These poems by Gyeong-Ji Yang are important historical records that portray the appearance of Soswaewon and the space outside it at the end of the 17th century. Unlike "48 Poems of Soswaewon" or "Soswaewondo," these poems arenot limited to Soswaewon and its surroundings; theyalso include areas from the village entrance upwardto the peak of the mountain behind the village. These poems can be divided into three main parts. Jiseok-ri and Changam-dong in poems 1 and 2 provide first impressions of the village in which the main Soswaewon garden is located, whereas poems 3 to 8 and poems 10 to 12 describe the space inside Soswaewon. Poems 13 to 30 depict the beautiful scenery around the outer garden of Soswaewon. In general, about 30% of the compilation in "30 Poems of Soswaewon" celebrates the inner Soswaewon, and the remaining 70% depicts the scenery around Soswaewon (i.e., views of the outer garden). It is presumed that Gyeong-Ji Yang employed this structure to achieve some type of order. Between the "48 Poems of Soswaewon" - also describing Soswaewon - and "Soswaewondo," which is a woodprint drawing of Soswaewon, "30 Poems of Soswaewon" offers the widest coverage of Soswaewon. Compared to "48 Poems of Soswaewon," which addresses the scene inside Soswaewon, new buildings such as the Jaeweoldang, Buhweondang, and Hancheonsa appear in "30 Poems of Soswaewon." Thus, the latter covers a much wider range. Chimgye Munbang - Gwangpunggak, Yangdandongo - Aeyangdang, Byeongseogjuggeun - Jajukchong, etc. are mentioned in both compilations. The use of a wide range of natural objects in these 30 poems, including mountains, birds, and the sky (instead of trees and flowers), shows that the author perceived Soswaewon as an area with a much higher and wider view than that of a typical living space. Moreover, natural regression ideologies, or seclusion ideologies, are evident.

Recently, child safety map making education has attracted attention as a way to reduce crimes against children. In Korea, the Ministry of Gender Equality and Family organized a child safety map making education program in 2011. The program's manual was revised in 2013 and the Ministry implemented it as a project to promote the rights of women and children. Child safety map making education aims to raise a child's understanding of their neighborhood, to have voluntary control and normal consciousness as a local inhabitant, to be aware of wrong behavior and crime, and to be part of creating a safe urban environment. However, when compared to educational programs in other major developed countries, the child safety map making education program in Korea currently does not improve a child's awareness of their surroundings. In this workshop study, we proposed and ran a new program to improve children's awareness of their environment based on the active participation of children in the existing safety map educational program. The workshop was held for 4 weeks for 48 students from 5th and 6th grade at Osan Daeho Elementary School. We analyzed this new program's effects with the following results. First, an analysis of the effects of the program on children's recognition of safe and dangerous spaces revealed that their understanding of these spaces increased by 30.4% after the workshop. The safety-related factor in the mind map key concept increased from 0.94 to 4.94, indicating that the children's perception of neighborhood risk and safety factors improved. Second, the analysis of the effects of the program on the children's coping ability in dangerous situations showed that their understanding of how to deal with dangerous situations increased by 11.3%. The children's understanding of facilities they could ask for help, such as police boxes and child safety guard houses, improved by 17.9%. Third, analysis of the effects of child safety map making education on children's understanding of their neighborhood, their perception of responsibility in the neighborhood, and their neighborhood attachment showed that these levels of children's understanding of the neighborhood improved by 6.0% after the workshop.

This study's purpose is to research the correlation between property and the major festivals with media art of exemplary 3 cities among 8 Unesco Media Art Creative Cities. As a result, it is drawn a conclusion that the below strategies are necessary to achieve success for Unesco Media Art Creative City. First, from the Creative City's point of view, on the basis of the maximization of various merits such as history, natural surroundings, and human resources of the city, it is necessary to reconcile a vision of the city and an identity of Media Art Creative City, and to seek for continuous growth of the city by consistency and durability of control tower within the local government. Second, from the local festival's point of view, it is necessary to provide a differentiated service in the existing media art festivals, to attract the fusion of media art and festivals, and the diversification and the popularization of media art programs. And, it needs to lead to involvement of young people with the fusion of on-line and off-line festivals, the fusion of analogue and digital festivals. In the conclusion, for the successful constructing of Media Art Creative City, it is necessary to maximize the merits of the city's own, to enhance the image for Media Art Creative City with the correlation between the merits and media art, and to differentiate the city's own various festivals, ant the same time, to converge them with media art technology. With these strategies, the local festival can make a new leap for global festival when it constitutes a whole with Media Art Creative City.
