The purpose of this study was to analyze the school location and site planning direction for land use planning of public land development. And this research proposed the direction of small park in school. So this research present the implication on urban planning and design for architecture, park-school complex. This study perform the relationship analysis on location of school and park. The result follows as this : 1) land use planning : Location and space of park-school must be checked in advance. Schools and parks are placed together. The park is located south of the school. 2) school site planning : Small field for dynamic activity is needed in school. The character of small park in school is relationship of educational programs. 3) management : CCTV is installed at school. Bright lights are placed in school. This result will be used in decision-making-process of land use planning, public land development construction, urban design and city policy.

The purpose The purpose of this study was to compare and observe research trends of sex education for young children·elementary school students·middle school students, provide base material for research on sex education, and present research prospects and tasks for the future. For this, 30 theses from Korean journals related to sex education for young children·elementary school students·middle school students from years 2000 to 2019 were extracted and analysis was conducted on the general trends (by research period and by academic field) of sex education and they were categorized by research topic, by research subject, and by research method. Research results showed that, with research period, research increased in the mid-2000s and with journal trends by research subject, and was published in 24 journals. Second, with regard to research topic aspects, most studies looked into 'sex education perceptions and conditions' and research dealing with 'gender concept development' and 'program development and teaching method strategies' also increased. Third, in terms of the research subjects, there were 9 papers for children, 6 papers for elementary students, 14 papers for middle school students, 2 for high school students, and 9 papers for teachers and parents. Fourth, with trends according to research methods, the quantitative research method of 'questionnaires' was used most and following were 'literary studies' and 'interviews', in that order. Reflecting these research results, discussions were presented and proposals for future studies were made.

Here we report our recent result of a new semiconductor material, which has an asymmetric structure. The synthesized molecules consist of anthracene and thiophene connected by bridged ethylene and substituted with hexyl or dodecyl groups as pendants. The semiconductors were synthesized using a McMurry coupling reaction between anthracene-2-carbaldehyde and corresponding 5-hexyl(or dodecyl)thiophene-2-carbaldehyde. A first investigation of synthesized asymmetry AVHT (9a) and AVDT (9b) for the physical properties showed that they have high oxidation potential and thermal stability. The devices prepared by using AVHT (9a) and AVDT (9b) showed the mobility of $2.6{\times}10^{-2}cm^2/Vs$ and $4.4{\times}10^{-3}cm^2/Vs$, respectively, in solution processed OTFTs.

The problem should be approached in terms of recovering essential functions of technical high school and identification to supply stable and quality human resources in technical sector. An adequate space programming for technical high school is needed to educate effective skills and techniques. Considering the education directions of vocational high school, the article covers principals of technical school's construction plan and directions and, based on this, suggest the way of estimating the scale in construction plan of technical school. Through this research, systematic and reasonable space planning can be possible. The range of this research is based on development directions of society and education and an objective standard in a newly reformed the 7th Stage of Education. In addition, the research is limited to technical high school among kinds of vocational high school. The purpose is to redefine the role of technical school that face identification crisis currently, comparing to the past, and to suggest a more effective space planning. The research limits the space to classes for specialized subjects, a core space for education in technical school among diverse spaces.
