The purpose of this study is to search for the effective way of development in managing Open Education Schools by analyzing obstacle reasons for school management of elementary school teachers on the basis of classroom site. This study researched 240 teachers and head teachers in three cities and counties of Chungbuk province through questionnaires which enquire obstacle reasons for Open Education. This research regarded 9 items including curriculum management and teaching method as main factors for consisting of Open Education School. And this analyzed the reactions from the percentages of interviewees. As a result of this analysis. obstacle reasons are as follows. 1. priority for academic background and the lack of school facilities and materials. 2. deficiency of teachers' belief in Open Education and unskilled practice. 3. closed situation in decision making and communication. 4. unreasonable management of finance and school facilities.

On account of increasing interest of substantiality in these day, it is needed to make an effort to establish an environmentally sustainable production system for the construction works. Although practical affairs and researches are in progress to reduce and recycle construction wastes, as a result of a research, there are still obstructive factors on waste reduction and recycling which they don't interact efficiently between waste disposal process of the construction area and waste disposal company. As a plan to revitalize reduction and recycling of construction wastes, this research focuses on finding obstructive factors and giving solutions to reduce and recycle construction wastes which comes from construction process and construction industries. To meet the needs of the research, firstly relatively significant construction wastes (concrete, soil, brick, block, asphalt, plastic, lumber) were identified. On site level interviews with management of disposal companies and construction sites were conducted as well, focusing on typical waste disposal process. Throughout this interviews, obstructive factors were conducted. A result of the research, the authors suggest an improved approach on disposal and recycling for construction waste by prioritizing the identified factors and ranking the importance level of each factor. And, by identifying factors obstructing reduction and recycle of construction wastes, this research suggests improved disposal process of construction waste.

The purpose of this study is to examine the effects of the factors that hinder innovation of SMEs on innovation activities of Korean firms. Many existing literature studies remain focused on factors that promote innovation activities. However, in order for companies to promote innovation, it is important to analyze the factors that hinder innovation as well as those that promote innovation. In this study, we analyzed the relationship between technological innovation inhibition factors and technological innovation performance of 4,075 SMEs in Korea using the Korea Institute of Science and Technology Policy statistical data. The research model and hypothesis test of this study consist of three stages. First, the reliability of the variables used was verified using exploratory factor analysis. Second, the proposed hypothesis was modeled using structural equation modeling. Finally, validity of the structural equation was verified using confirmatory factor analysis. As a result, the lack of need for innovation influenced innovation performance and the government support system mediated them. SMEs should establish technological innovation strategies to maximize the effect of technological innovation with limited resources, and government should make polices to promote innovation of SMEs. It's expected to be used in the case of establishing a support policy.

In this report, we test the features that the outside environment of subscriber lines have an effects on ADSL's electrical transmission performance with a suspected cases of line. I observed an influence of AM broadcasting jamming, and also analysis of an incoming lines of various kinds, a line distance, a connection way, Bridge Tap influencing ADSL's electrical transmis-sion performance. To have a maximum effect of Adsl electrical transmission, I came to a conclusion that we have to make use of the older copper wire cable line to fit the situation at the present and we must change it into the excellent optical fiber cable one by one.

The sum of each work duration are entire period in construction project. Each work occurs to be late, the total period of construction project will delays. Therefore, the total period of construction project will not be delayed if probability of working progress makes higher. Finding each work's constraints performs constraints analysis in process of construction for checking probability of working progress. Grasp work's constraints through the constraints analysis and removes. This research will show preventing delay of consruction project, through constraints analysis process.

This is a comparative descriptive research conducted to compare work obstacles and safety culture perceptions of elderly welfare facility employees in Korea and Japan. The number of subjects are total 680 including 460 Japanese employees, working at elderly welfare facility in city 'N', and 220 Korean employees in city 'A' and 'S' of province 'K'. This study had been conducted from April 1, 2018 to August 30, 2018 and the data was analyzed by x2-test, t-test, ANOVA. As a result, work obstacles were korea and japan, there were no statistically significant differences between two groups. In the safety culture perceptions, employees of elderly welfare facility in Korea showed significantly higher level of safety culture perception than employees of that in Japan. furthermore, it is revealed in both countries that the less work obstacles they have, the higher safety culture perceptions they get. And it is a work obstacles that affects safety culture perceptions. Lastly, it is expected that the result of this study can be used as basic data for the improvement of working environment and for the strategy development in human resource management to enhance the safety culture perceptions and to reduce work obstacles.

Since enforcement of the anti-prostitution law, in spite of systematic setting helping escape prostitution of the women who engage in prostitution that they have had the will lasting prostitution. Therefore, this study aimed to devise intervention plan helping their escape prostitution and return to social by examining individual and structural factor obstructing their escape prostitution The data were collected through the in-depth interview and text. And these were analysed according to coding, constitution of concept, matching, construction of explanation on the phenomenon. The nine women who engaging in prostitution were participated in this study. As a result of the data analysis, 46 concepts and 10 categories were generated. By classification of individual and structural factor, the outcomes of an interpretation were as follows: The cause obstructing Prostitutes' escape prostitution were (1) distrust on the policy of the government, (2) life-script was made by reaction-formation, (3) predestined resignation caused by anxiety, (4) body as capital goods, and (5) the commensal model with pimp.
