The purpose of this study is to provide the basic data on the development and application of parent education programs and suggest the direction of future studies by analyzing the trends of research articles related to parent education programs. For this, the articles on 'parent education programs' written in Korea from 2004 to 2014 were collected and analyzed. The number of articles analyzed is 202 in total: 41 doctoral theses, 88 master's theses, and 73 academic theses. Firstly, the basic trend of research of parent education program was examined per object and subject. Secondly, the trend of research of the development and implementation of parent education programs was examined by dividing the programs on the basis of the ground for development, object of application, subject, type of program designing, the number and hours of the program, method of conducting the program, program educator, program effects. etc. The results of the analysis of the data made it possible to find out the process of development and implementation of parent education programs conducted in Korea. Such research results were summarized according to the research problems and suggestions for follow-up studies were made on its basis.

A space launch vehicle system represents a typical example of large-scale multi-disciplinary systems, consisting of subsystems such as mechanical structure, electronics, control, telecommunication, propulsion, material engineering etc. A lot of cost is required to develop the launch vehicle system. A precise planning of R&D cost is very essential to make a success of the launch vehicle development program. Especially in the early development phase of a new space launch vehicle system, cost estimation techniques and analogy from past similar development data are very useful methods to estimate a development cost of the launch vehicle system. Now Korea Aerospace Research Institute is in charge of the KSLV-I (Korea Space Launch Vehicle-I) Program that is a part of Korea National Space program. KSLV-I Program is a national undertaking to develop launch capabilities to deliver science satellites of a 100kg-class into a low earth orbit. It is hereafter, going to plan to develop a new korean space launch vehicle. In this paper, first the development costs of well-known launch vehicles in the world are presented to provide a reference to make a development plan of a new launch vehicle. Second this paper introduces the present status of cost estimation applications at NASA. Finally this paper presents the results from application of a TRANSCOST, a parametric cost model, to derive a cost estimate of a new launch vehicle development, as an example.

There has been researches for effective education. Among them, many researchers are striving to apply Zone of Proximal Development of Vygotsky which is emphasizing the social interaction in the field of teaching and learning. Researchers usually research based on individual or small group of students. However the math class in school relies on system that one teacher teach many students in reality. So this research will look for the effect that the teaching and learning program based on Zone of Proximal Development of Vygotsky by designing the teaching and learning program which is based on scaffolding structuring to overcome the zone of proximal development in many-students class. The results of this research are as follows: First, the studying program considered the theory of Vygotsky has a positive effect on improving the mathematical achievement of elementary student. Second, the studying program considered the theory of Vygotsky has a positive effect on improving the student's studying attitude upon mathematics.

The city of 'G' has been made a number of achievements with its science program as a part of public library's cultural program during the last 5 years. Recently, the national science centre has been established in the same city, the debate is now needed whether the science program in the public library have reasons to be maintained or to be reduced. The aim of this research is on the operating strategies of the science program in the public library. The research methods include case studies of operational strategies in domestic and foreign science centre, the level of satisfaction of local citizen on the science program, the vision of science program in the advancement of public library in the $21^{st}$ century. In results, the research proposes that the science program in public library should be maintained, but with locally characterised programs. In addition, the study also advised on the provision of scientific information, the strengthened search functions, and the development of user-centred services for those in science fields.

A web-based program life-cycle management(PLM) system is introduced to implement the system engineering processes and to provide the development traceability online. This information system aims for the realization of essential system engineering management techniques currently applied to the space launch system development program including management of configuration and data based on the work breakdown structure(WBS), WBS, bill of materials and mass properties. The system enhances communication and gives access to the development data with relevant information such as data-to-data relation and approval status/history through the web, and preserve all of the development data throughout the program life-cycle. Further improvement of the system is planned to implement the program management processes and co provide integrated information useful for the programmatic decision making.

The Smart UAV Program was motivated by a huge potential market, a various application and future core technologies. The Smart UAV system is defined as the advanced air vehicle with the smart technology such as collision awareness and avoidance, healthy monitering and self-recovering, intelligent active control. Due to the broad interest by government, industry and academia, Smart UAV development center and government steering committee were established. The organization of the Smart UAV program consists of domestic/international companies and academia. In this paper, the process and application of system engineering was introduced for Smart UAV development program.

Design for Six Sigma (DFSS) has been implemented in many companies to enhance their business performance and customer satisfaction. However, DFSS has not been widely applied to the aircraft industry which operates large, complex development programs. In this paper, the characteristics of an aeronautical product development program are analyzed to figure out the limitations of current DFSS methodology and the prerequisite to deployment of DFSS at the program level is suggested.

In this paper, EVMS procedure for KHP program is presented. Research and development of a defense system as a long lead program has a high probability of cost growth due to the uncertainty and risk. Therefore, meeting schedule, technical performance and preventing excessive cost overrun are the main concerning point to successful research and development program. EVMS(Earned Value Management System) is a program management system using earned value to control cost, schedule and technical performance. In order to control cost and schedule and to meet technical performance requirements of the KHP research and development program, it is necessary for us to adapt EVMS to the program.

The purpose of this study is to conduct a systematic review of the development and implementation of family resilience programs focusing on published papers in domestic Journals, to provide basic data on development of future family resilience programs, and present research directions. For this, I analyzed the contents of 16 published papers in domestic Journals from 2003 to 2016. The analysis was divided into the performance elements of the program and the development factors. The six sub-areas of program execution factors are subjects of study, research design, program duration and time, facilitator, research method, scales and effect analysis. The three sub-areas of the program development factors are the development base, the purpose of the program development, and the main content of the program. Based on the results of this study, it is necessary to develop a family resilience program considering the various problems of each family and the specific environment in the future.
