According to the change of the life environment and economic growth, the more highly a city has developed, the more concentrated is the urban function. That is, a city is required for adding more infrastructure. But, both limited land resources and financial problems made it impossible to add infrastructure. So, the necessity of multi-dimensional planning of urban infrastructure was recognized. Especially, in the urban residential area, a mixed-use of the playground of a school and the empty space of a park is desired to serve the issue of insufficient parking spaces. Schools and parks are closely connected to the center of a town, and playing a central role for the town life. For this reason, they are highly demanded in urban residential areas and also expected to be effective. However, we need to consider not only parking convenience but also the safety of users in design process, because people using parks and schools include young students and the elderly. In this study, we mainly examined physical characteristics and the utilization of schools and parks with parking facilities in urban residential areas. Then, we analyzed cases through comparing and evaluating in terms of convenience and safety. and weighed up advantages and disadvantages of each through the comparison of the schools and the parks having parking facilities. The results of this study are expected to provide fundamental references for preparing design standards for such facilities.

For the young period, privacy is a crucial factor in establishing one's own identities, values and relationships. The capacity of residential environment to protect individual's privacy takes considerable part in influencing psychological and physiological development of adolescents. This study analyzed adolescents residential values and the elements of spatial plans for the passage and outdoor in Apartment Design Competition of Suwon A district in 2008. One hundred and ten middle and high school students living in Metropolitan area were selected and questionnaire was conducted during February 7 to February 15 in 2009. The data was analyzed by SPSS 11.0 program using one-way ANOVA and crosstab. The study results were summarized as follows; First, the adolescents valued 'safety' the most, regardless of their age and gender and the safety of adolescents commuting should be considered. Second, protecting their own private territories was next important element among other elements. Privacy can be protected by using movable walls, changing the doorway, dividing parents' and adolescents independent territory. Third, in terms of convenience, choosing location of children's room and walking way should be considered. Forth, from the survey, demand for indoors leisure activity was highly valued and required for aesthetic point of view. Considering the sculptures and facilities must satisfy the aesthetics and practicality.

We studied in order to find out suitable amounts of board by visual effects to establish indoor boards and human psychological effects by several board designs. Thirty students of C university were tested in constant temperature/humidity room and interviewed after tests. The experimental visual images were projected from 54' TV. As a result, the board length that showed high preference and satisfaction was the 90cm both horizontal and vertical direction. We found that vertical board gave an impression of a linear and narrow shape and the horizontal board gave wide space and cool feeling from psychological analytical study. The factors affecting satisfaction in horizontal direction were refreshing, intimacy, beauty, area, splendor and those in vertical direction were a sense of security, beauty, texture, intimacy, continuity, extensity, natural feeling. We got 5 factors from the result of factor analysis in order to get psychological factor axis. Those were pleasantness, artificiality, openness, dynamics, refinement. By multiple regression analysis, the factor pleasantness had the highest impact on visual satisfaction on scenary. The study on psychological factor difference by analysis of variance showed that psychologically feeling amount about pleasantness, artificiality, dynamics, refinement, and openness had statistically meaningful difference despite of board direction. We found that the 90cm had a tendency as a changing point leading image change by the investigative analysis of board direction based on factor points.

The objective of the present study is to investigate healing design attributes for adolescent patients and to identify the relationship among healing design attributes and the meaning of home. This study examined the environmental preferences of American adolescents for hospital rooms to investigate age-appropriate healing design attributes. The health-related quality of life (HRQOL) concept was adapted to this study as a theoretical framework. One hundred six American adolescents participated in the survey. Participant adolescents consisted of two groups by their health status: forty-seven adolescent patients who were waiting for their surgical operations in waiting rooms and fifty-nine healthy high school students while they were at school. Participants aged in range from 14-year to 18-year olds with a mean of 16-year olds. Data collection consisted of two different instruments: Emotional state survey with demographics and environmental preference survey. Environmental values that are important to adolescents were control of privacy, having outside view, and quiet places to go. However, staying in a single-bed room for hospitalization is ranked the lowest score for the participating adolescents. Adolescents who perceived higher stress level preferred to have quiet places to go, to control over privacy and to have outside view significantly. The study resulted that the most important design attribute for American Adolescents was "privacy control", which is the essence of the meaning of home. There are some significant discrepancies in environmental preferences of hospital rooms by different genders and different health status.

This study investigates the effects of over-parenting behavior and peer-alienation on adolescents' school adjustment and explores the mediating effects of smartphone dependency on the above relations. The subjects were 1,882 first grade students in middle school selected from the 7th year data of the 2010 Korea Children and Youth Panel Survey (2010 KCYPS). Data were analyzed by descriptive statistics, Pearson's correlation, structural equational models, and Sobel test with SPSS 21.0 and Amos 18.0. The findings were as follows. First, there was no significant difference in the school adjustment according to gender. However, boys were higher in the perception of over-parenting behavior and peer-alienation, and girls were higher in smartphone dependency. Second, peer-alienation and smartphone dependency had negative impacts on the school adjustment. But over-parenting behavior had no significant effect on school adjustment. Third, smartphone dependency played a mediator role between over-parenting behavior and peer-alienation as well as the school adjustment. Fourth, there were no significant differences between boys and girls in the relations among over-parenting behavior, peer-alienation, smartphone dependency and school adjustment. But there was a slight difference in influence. The findings of this study suggest that interventions on how to use smartphone correctly are important for improving adolescents' school adjustment. In addition, gender differences in school adjustment should be considered for a better understanding.

2010년 이후 분양되는 오피스텔은 관련법령 개정에 따라서 주거공간으로 활용이 되며 교육환경 면에서 소비자들이 선호하는 지역의 주택에 대한 대체재로 역할을 하고 있다. 이에 본 연구는 주택의 가격형성 요인 중 하나인 교육환경이 주거공간으로 할용이 되는 오피스텔의 전월세 가격에 미치는 영향을 분석하였다. 2015, 2016년에 거래된 서울시 소재 오피스텔을 분석대상으로 하고 오피스텔에서 가장 가까운 중 고등학교의 전국단위 학업성취도 평가와 특목 자율고 진학률을 주요 독립변수로 가지는 분석모형을 헤도닉가격모형과 인공신경망기법을 통해 실증 분석하였다. 분석 결과, 교육환경 관련 변수의 값이 증가할수록 전월세 가격에 정의 영향을, 학교와의 거리는 멀어질수록 부의 영향을 미치는 것으로 나타났다. 또한 다른 독립변수 또한 주택 관련 연구와 유사한 결과를 보였다. 이 연구는 오피스텔이 업무용보다는 주거용 부동산 성격으로 변하고 있으며, 이를 주택가격에 내재된 특성 중 하나인 교육환경을 통해 분석하였다는데 의의를 가진다.

교육용으로 사용되는 피삭재(소재)는 SM20C, Al6061, 아크릴 등의 소재를 사용한다. SM20C 소재는 탄소강으로서 자격증 시험 및 기능경기대회에서 많이 사용되지만 산업현장에서도 많이 사용된다. Al6061 소재는 탄소강에 비하여 경도가 낮아지고 전성(연성)이 강한 소재이기에 공구의 구성인선이 많이 발생하는 소재라고 한다. 아크릴 소재를 이용하여 학생들에게 실습지도 하면 어느 부분에서 과다 절삭으로 인하여 진동이 발생하고 공구의 파손이 발생하는 소재이다. 이러한 과정에서 5축장비인 2NC헤드에게 가해지는 충격이 정밀도 제어에는 어느정도 영향을 줄 수 있는지 알아본다. 5축장비의 가장 취약한 부분은 AC축을 제어하는 헤드가 가장 약한 부분이라 할 수 있다. 이 부분의 정밀도 및 누적 공차가 발생할 경우 모든 제품의 정밀도가 떨어지는 현상이 발생한다. 따라서 2NC헤드의 핵심적인 부분, 스핀들 하우징은 Al7075 T6(미국 알코아사) 소재를 사용하여 진행하였다. 이 소재에서 작용되는 진동 및 절삭 과정에서 힘을 극한조건에서 유한요소 해석으로 적용되는 값을 밝혀 내고자 해석을 진행하였다. 이러한 해석 데이터를 활용하여 학생들이 5축절삭 보다 5축가공기의 구조를 보고 이해하는데 도움이 되기를 기대한다.
