Recently, the social debate about the fourth industrial revolution has been actively developed, and it is predicted that the 4th Industrial Revolution will have a great influence on our society, cities, residential and industrial spaces. Especially, it is anticipated that the technological development of the 4th Industrial Revolution will cause a wide range of changes in residential style and culture. Therefore, it is necessary to grasp the direction of future change in advance and proactively respond to future tasks and strategies need. The purpose of this study is to predict the direction and characteristics of the mid - to long - term changes in future housing that will be brought about by the 4th Industrial Revolution and to define future social, spatial and technological impacts and issues and to find policy measures for them. STEEP (V) as a methodology for forecasting future has been used. It is a process of deriving technical and social issues by using Big Data. It collects various keywords and draws out key issues and summarizes social change patterns related to each core issue. The proposed strategy for future housing prediction and countermeasures can be used as a basic data for future directions of housing policy and suggests a process for deriving reasonable and reasonable results from multiple data sets rather than accurate prediction.

Since future climate scenarios indicate that extreme precipitation events will intensity, probable maximum precipitations (PMPs) without being taken climate change into account are very likely to be underestimated. In this study future PMPs in accordance with the variation of future rainfall are estimated. The hydro-meteorologic method is used to calculate PMPs. The orographic transposition factor is applied in place of the conventional terrain impact factor which has been used in previous PMPs estimation reports. Future DADs are indirectly obtained by using bias-correction and moving-averaged changing factor method based on daily precipitation projection under KMA RCM (HEDGEM3-RA) RCP 8.5 climate change scenario. As a result, future PMPs were found to increase and the spatially-averaged annual PMPs increase rate in 4-hour and $25km^2$ was projected to be 3 mm by 2045. In addition, the increased rate of future PMPs is growing increasingly in the future, but it is thought that the uncertainty of estimating PMPs caused by future precipitation projections is also increased in the distant future.

This study investigated the relationships between ADHD trait, emotional music use, relationship initiation, and expectation for future life in early adolescence, and to verify path model to predict the expectation for future life. The participants were 347 male and female middle school students, their average of ages was 13.35 (SD=.91). The ADHD trait was measured with self-report scale, emotional music use and relationship initiation were measured with sub-scales of Use of Music Inventory and Interpersonal Competence Questionnaire, and expectation for future life was measured with modified items of Satisfaction with Life Scale. Results revealed that ADHD trait was negatively correlated with relationship initiation and expectation for future life, whereas emotional music use was positively correlated with relationship initiation and expectation for future life. And, relationship initiation positively correlated with expectation for future life. The alternative model was adopted that included a direct path from ADHD trait to expectation for future life in the proposed model, rather than the proposed model in which ADHD trait and emotional music use affects expectation for future life through relationship initiation. The findings of this study should provide useful information for further studies and for professionals who try to promote the expectation for future life in early adolescence.

In this paper, we investigated the effects of mathematics classes using play-action programs in the course of mathematics education of future elementary school teachers. This study was conducted with 43 junior university students who selected 'Play Mathematics' in 2006. All the participants in this course was divided 11 groups. Play-action mathematics programs was consisted of 12 themes. For example, there was tangram, somacube, hexamino, tessellation, geoboard etc. In the beginning of lessons, we investigated theses themes itself through plays, puzzles, games, and computer programs. And next time, we investigated the relationships between these themes and elementary mathematic textbooks(i.e. mathematical contents). In 14th and 15th lessons, all the groups took a project presentation lessons that included all things about play mathematics in all group categories. And they developed two themes of play mathematics in accordance with grades, contents, levels as course tasks. Through this study, three educational effects induced. First, future elementary school teachers have a deep understanding about play-action mathematics. They are interested in these play themes, and take part in these play mathematics programs of their own accord. And they realize that these play themes are related to elementary mathematics. Second, future elementary school teachers' attitude and mind about mathematical are improved after this course. Third, future elementary school teachers comprehend various instruction methods relating to play mathematics. Therefore, we suggest that future elementary school teachers need to have many opportunity to experience and develop a mathematics classes using play mathematics.

The objectives of this study were to explore to upbringing system for the future farmers of the 4-H Clubs, future farmers organization and the Center for 4-H in the USA to suggest some implications to 4-H programs in Korea. To train future leaders in agricultural and agri-business areas leaders in the United States felt the need to create various organizations such as 4-H Club, Future Farmers of America (FFA), Young Farmer Association (YFA), and cooperate each other. The members in future farmer's groups benefit from opportunities and involvement of farming and agri-related activities and contribute to improve their communities. One of them, the 4-H Club remains strong in the country covering young people as members and adult as volunteer leaders. Youth in 4-H learn by doing, and members find opportunities for leadership. 4-H members contribute to their family, community, and country in meaningful ways to make a difference. The Center for 4-H has provided a range of challenging opportunities around the arts, sciences, environment, technology, business, animals, foods, and health while always stressing leadership and citizenship for 4-H members. The Center has been supporting research, teaching, and outreach in community based non-formal youth development education. The Center is particularly interested in youth development opportunities including foster resiliency, promote safe and healthy behaviors, and support youth in communities in various ways.

We have investigated the impact of coffee ring effect on the inkjet-printed $Al_2O_3$ thick films. In a single solvent system such as Dimethylformamide, the coffee-ring-pattern has appeared on the edge of sessile drop after evaporation. The peak-to-valley height difference in $Al_2O_3$ coffee ring is over 2um. This non-uniform deposition of $Al_2O_3$ over the surface leads to sever surface roughness of the inkjet-printed films. However, we have manipulated our printing parameters to improve the surface roughness and the packing density of the printed $Al_2O_3$ films. Our inkjet-printed $Al_2O_3$ films show 10 times smoother surface than the initially printed sample's surface. Also the packing density of the printed Ah03 film becomes 70% of high packed $Al_2O_3$. In this presentation, we would like to present the key process parameters of the inkjet printing process to overcome the genetic coffee ring problem.

In this research, we investigated the effects of mathematics education in using Socrates , method in a course of mathematics education in teacher's college. And we proposed some suggestions for education of future mathematics teachers. This study was conducted with 44 university students(third grade) who entered the department of mathematics education (future mathematics teachers) in 2005. We took a course in curriculum that was required for the future mathematics teachers in my department. In this course, we began with the reading the famous dialogue between Socrates and Meno's slave. And we analysed Socrates' questioning of Meno's slave and tried to understand what this dialogue is implicating in mathematics education. All the participants in this course was divided 11 groups. Each group designed a school mathematics class plan using Socrates' method and practiced their teaching plan by a performance(students' announcements). Through the analysis of research data. Five effects of mathematics education in using Socrates' method for future mathematics teachers were induced. Therefore, we suggest that future mathematics teacher need to have many opportunity to design and practice a mathematics teaching plan by using mathematics teaching-learning methods taught in their course.

Earnings management is a collection of management decisions which firms do not report the true performance. Many prior studies suggest that earnings management could be the results of either managerial earnings management or manager's private information for future performance. This study attempts to delve into the fundamental implications inherent in earnings management by analyzing how earnings management affects future firm performance in public institutions. If discretionary accruals as a measurement of earnings management embrace manager's private information, it will have a positive effect on future performance in succeeding period. In contrast, if discretionary accruals embrace manager's opportunistic earnings management, it will have a negative effect on future performance in succeeding period. Empirical findings are summarized as following.: Earnings managements are negatively associated with future firm performance for all succeeding period. This negative relationship continues for all succeeding period. The overall results can be serve as a evidence that the discretionary accruals capture opportunistic earnings management on average.

다상 고정층 촉매반응기(Multiphase catalytic fixed-bed reactor)에서 기체 유동과 관련, 반응기 내부 구조 디자인에 따른 feed 가스의 분산성 변화를 분석하였다. 다상 촉매반응기의 경우 feed gas의 투입방법이 전체 공정의 반응효율을 크게 결정하는바 본 연구에서는 산업현장에서 활용도가 높은 환형 가스 주입부로 구성된 다상 고정층 촉매반응기를 대상으로 다양한 조건하에서 촉매 반응기 내부에서의 feed가스 분산성 변화를 분석하였다. 다상 촉매반응기의 feed gas 주입과 관련하여 다양한 방안이 제시되고 있는데 그 중 환형 가스 주입방식을 활용하는 방법은 타 기술대비 상대적으로 저렴한 투자비와 좁은 작업공간하에서 기체의 분산성을 향상 시킬수 있는 특징이 있어 실제 상업 공정에서의 활용성이 매우 높다. 본 논문에서는 특히 기-고 촉매 반응기 내부 반응기체의 분산성 향상을 위해 환형 가스 주입장치 내부에 설치된 가스 주입홀 구성방법에 따른 반응기 내부 유동을 분석하였다. 분석결과 주입홀의 위치가 가스 투입라인의 접선방향에 위치하는 것은 전체 분산성에 큰 영향을 주지 못하며 대부분 가스투입 입구와 맞은편 부분에 위치하는 경우 분산성이 향상되는 것으로 분석되었다. 결과적으로 환형 가스주입장치의 최적 설계는 feed 가스의 분산성에 큰 영향을 미치므로 초기단계에서 이러한 점을 고려한 설계 및 분석연구가 선행되어야 할 것으로 사료된다.
