The purpose of this study that was based on the theory review about the practical use necessity of school landscape was to survey on the awareness of elementary school teachers about the applications of school landscape for environmental education. This study was carried out through the review of literature, the questionnaire to 132 elementary school teachers in Seongnam City. The findings derived from this study were as follows : First, School landscape is an important field as environmental education resource for the improvement of school environmental education. Especially, for the improvement of environmental sensitivity through field-experience learning, the practical applications of elementary school landscape is very important and urgent in aspects of environmental education theory, accessibility, and convenience. Second, Most of responded teachers give an affirmative answer about the field-experience learning for school environmental education and the necessity of practical use of school landscape for field-experience learning. Several the improvement to use elementary school landscape for environmental education being suggested by teachers are the increase of financial support, the magnification of school area, and the school landscape planning and design in consideration of environmental education by landscape architect expert. Third, Above half of teachers don't agree to use the roof garden for environmental education because of the safety of students and the school building construction. Fourth, Teachers are more satisfied with the status of school landscape maintenance than the practical usability of school landscape in aspect of environmental education and the facilities in school landscape. Teachers think that the most important functions and roles of school landscape is psychological factor.

The maintenance of school building is pivotal issue. However, it is difficult to obtain basic analysis data for LCC(Lifecycle Cost) analysis and maintenance planning of school building. Therefore, this study proposed System Dynamics(SD) techniques to make maintenance decisions for school building. The interaction between the major parameters related to the aging of a building, maintenance activities, and cost were expressed in Causal Loop Diagram. Based on this, the formula for the relationship between causal maps was defined and converted to Stock and Flow Diagram. Through the completed SD model the 50-year plan of 214 educational building were tested by considered in account budget, maintainability, and budget allocation opinions. As a result, the integrated SD model demonstrated that it can support strategic decision making by identifying the status class and LCC behavior of school buildings by scenario. According to the scenario analysis, the rehabilitation action of preventive maintenance that primarily repairs the buildings in condition grade C showed the best performance improvement effect relative to the cost. Therefore, if the proposed SD model is expanded to consider the effects of other educational policies, the crucial performance improvement budget can be estimated in the long-term perspective.

This paper presents an environment for rule-based English-Korean machine translation system, which supports the translation domain adaptation and the continuous translation quality improvement. For the purposes, corpus is essential, from which necessary information for translation will be acquired. The environment consists of a corpus construction part and a translation knowledge extraction part. The corpus construction part crawls news articles from some newspaper sites. The extraction part builds the translation knowledge such as newly-created words, compound words, collocation information, distributional word representations, and so on. For the translation domain adaption, the corpus for the domain should be built and the translation knowledge should be constructed from the corpus. For the continuous improvement, corpus needs to be continuously expanded and the translation knowledge should be enhanced from the expanded corpus. The proposed web-based environment is expected to facilitate the tasks of domain adaptation and translation system improvement.

By analyzing five in-depth case studies of suppliers in newly emerging Vietnam's motorcycle industry, this paper explores the differences in patterns and processes of capability improvement of suppliers who participate in different kinds of supplier-assembler network with different structures. The paper finds the correlation between the kinds of suppliers' capabilities improved and the structure of networks they participate in. While suppliers in arm-length networks can improve more upstream capabilities (structure design, process desist), suppliers in embedded networks can improve more downstream capabilities (process design, process setup, process maintenance and delivery control). Two capability improvement patterns of firms in newly emerging economy are indicated. The first pattern is asymmetrical improvement, either upstream or downstream capabilities, by participating in either arm-length or embedded networks. This pattern obstructs the suppliers to meet the requirements of new buyers rho come from different kinds of network. The second pattern is symmetrical improvement by joining both arm-length and embedded networks.

Incidental envy is known to motivate self-improvement behavior. This phenomenon occurs in part because feelings of inferiority guide subsequent behavior in a way to self-improve, after experiencing envy. However, no research has yet examined whether this tendency may be affected by social context: private versus public. Although extant literature suggests that envy generally leads to self-improvement, we demonstrate that this effect may be mitigated under public social contexts. Across two studies, we find that although incidental envy generally increases self-improvement behavior (e.g., effort exertion and charitable giving) in private social contexts, this tendency is attenuated under public social contexts. We conclude with a discussion of theoretical and practical implications of this finding.

Since rapid industrialization of Korean society, out-of-village roads have been greatly improved, while almost all of in-village roads have not been fundamentally improved yet. Unless village roads should be improved in relatively comparison with trunk roads, it has been widely recognized that grass rooted achievement of accessibility revolution not be realized. In this regard, this study tried to develop evaluation indicators system for improvement of village roads. The evaluation indicator system on village road conditions was proposed which is sub-categorized as structural improvement of road itself, its communication serviceability and public securing level of property rights of road site. The system has 6 indicators(2 of each subcategory);good pavement ratio and over 3m wide road length ratio, ratio of household fronting under 2m wide road and connectivity of road network, ratio of registered as 'road' in land category and ratio of publicly owned road sites. In the final conclusion, village roads in rural Korea have been generally in worse condition regardless of whether prior improvement works or not, except some of recent plan-based improvement villages.

This study aims to suggest an energy consumption improvement plan for university buildings through an analysis of energy consumption. Upon a simulation of subject building to interpret energy consumption, it was found that 154.07kWh/$m^2$ of energy is consumpted annually. Improvement of design elements can cut down the energy consumption to 135.61kWh/$m^2$ according to an energy reduction analysis related to envelope performance improvement. Additional improvement of lights and heat exchanger can curtail annual energy consumption to 108.32kWh/$m^2$. Also, an analysis of energy consumption while increasing indoor temperature gradually showed that the two factors are in proportion. $6^{\circ}C$ higher temperature requires over twice of the current energy. Based on this survey result, performance improvement due to building management and envelope elements which influence to building cooling and heating loads can curtail building energy consumption.

The expansion of a country's ecological footprint generates resources for economic development. China's import bill and carbon footprint can be reduced by investing in green transportation and energy technologies. A sustainable environment depends on the cessation of climate change; the current study investigates nuclear energy efficiency, economic complexity, air transportation, and industrial improvement for reducing environmental footprint. Using data spanning the years 1983-2016, the dynamic autoregressive distributed lag simulation method has demonstrated the short- and long-term variability in the impact of regressors on the ecological footprint. The study findings revealed that economic complexity in China had been found to have a statistically significant impact on the country's ecological footprint. Moreover, the industrial improvement process is helpful for the ecological footprint in China. In the short term, air travel has a negative impact on the ecological footprint, but this effect diminishes over time. Additionally, energy innovation is negative and substantial both in the short and long run, thus demonstrating its positive role in reducing the ecological footprint. Policy implications can be extracted from a wide range of issues, including economic complexity, industrial improvement, air transportation, energy innovation, and ecological impact to achieve sustainable goals.

Objectives: To review trends of clinical trials on Korean medicine treatments for postoperative sleep improvement. Methods: We searched randomized controlled trials (RCTs) on Korean medicine treatments for postoperative sleep improvement from ten domestic and foreign databases. Sample sizes, diseases, types of operation, diagnosis tools, pattern identification, interventions, outcome measurements, and main results of included studies were extracted and analyzed. Results: A total of 20 RCTs were selected. Most studies were published in China. The most common target disease was cancer, followed by cardiovascular disease. Most studies lacked detailed description regarding participants such as onset, duration of sleep disturbance, and preoperative sleep issues. Herbal medicine was the most frequently used in 12 studies. The most commonly used prescription was Suanzaoren decoction. The effectiveness of Korean medicine treatment on improving postoperative sleep was found to be significant in most studies. Conclusions: Korean medicine treatments might be effective in postoperative sleep improvement. However, the quality of included studies was low. Therefore, further well-designed research studies are needed to provide high quality clinical evidence on Korean medicine treatments for postoperative sleep improvement.

This study investigated the perception of pre - service teachers in order to find out how paper textbooks are used in high school classes and what improvement is needed. Firstly, the results of analyzing the perception about the utilization of textbooks are as follows. First, in the case of Korean language, social studies, mathematics, science, and English, textbooks were used most frequently, and most of the respondents did not use textbooks for arts and physical education subjects. Secondly, Korean language, social studies, mathematics, science, and English textbooks are most frequently used as teaching materials. Third, in the case of Korean, social, mathematics, science, and English subjects, in addition to textbooks, problem collections were used most frequently and arts and physical education subjects showed the most use of prints. Next, the results of analyzing the perception of the improvement method of the textbooks are as follows. First, in the high school class, the response rate was high in that Korean, social, mathematics, science, and English classes needed a textbook. Most of the respondents answered that they were not necessary for the textbooks of arts and physical education subjects. Second, in order to improve the textbooks, the most demanding textbooks focused on the core basic contents, followed by self - directed learning activities, competency centered contents selection, cooperative learning activities, and teacher self - development. The demand for digital textbooks was low.
