In this paper, we propose a two-stage group acceptance sampling plan for generalized inverted exponential distribution under truncated life test. Median life is considered as a quality parameter. Design parameters are obtained to ensure that true median life is longer than a given specified life at certain level of consumer's risk and producer's risk. We also explore situations under which design parameters based on median lifetime can be used for other percentile points. Tables and specific examples are reported to explain the proposed plans. Finally a real data set is analyzed to implement the plans in practical situations and some suggestions are given.

This paper addresses construction of a new network of invention education through the internet and creates a plan to apply it to practical invention education. We examined the status of invention education in Korea, the U.S., and Japan to consider problems of practical invention education and to draw a particular direction for the future invention education. Various papers, books, and documents related invention education were reviewed to make teaching and teaming strategies of invention education. Based on the analyses, criteria of teaching and loaming were identified as how to challenge teachers, students, parents, and administrators to successful implement invention education practices. Using the criteria of teaching and teaming, we designed a framework for a website and constructed a practical website concerned with invention education, including constructive components in the framework. This will require an experimental application during which teachers and researchers can do revisions and add supplementary information. This network system will provide practical information in regard to invention education and created a communications system for in charge of invention education.

The purpose of this study was to develop teaching-learning plans featuring the practical problem based instruction for character education in middle school Home Economics classes. Six elements of character education including trustworthiness, respect, responsibility, fairness, caring, and citizenship were identified and 21 practical problems were drawn as a result of analyzing the contents of Home Economics curriculum. Teaching-learning plans and hand-outs for students included four steps such as problem perception, practical reasoning, action, and evaluation that comprise the practical problem based instruction to solve the practical problems. The validity of the program was evaluated by 5 professors and 10 home economics teachers with 5-Likert scale. The result of 4.28 and 4.32 on average indicated that teaching-learning plans are appropriate to character education in Home Economics classes. The follow-up study needs to be conducted to apply the teaching-learning plans to Home Economics classes.

OBJECTIVES : Currently, the market for carbon emissions trading has been increasing. In Korea, it is known that traffic mode rate in bike transportation is low. However, if bike transportation system is encouraged and the traffic mode rate is increased, it would be possible to reduce carbon emissions through the trading market. In this study, a practical policy to activate the bike transportation system in Korea will be proposed and verified. METHODS : Past studies regarding bike transportation system in international and domestic metropolitan cities were analyzed. Moreover, detailed reviews on recent carbon emissions trading market were performed. In particular, SWOT analysis on the bike transportation system in Korea and policy topology analysis were conducted. RESULTS : Based on the literature reviews and SWOT analysis, a new bike transportation policy was proposed. Several actual plans to adopt in Korea were proposed. In addition, a new bike transportation policy was analyzed using policy typology model, and a business model related to the cost of implementing the system and CERs were also proposed. CONCLUSIONS : It is concluded that the proposed bike transportation activation policy and several practical plans to connect CERs and a business model including bus, subway, T-money and bike riders to give some incentive were effective and reasonable. It is desired that this study will help Korea to get CERs through bike transportation activation in the future.

This study developed an integrative curriculum design plan for Home Economics through a deliberation method. This study established a research framework to integrate the deliberation models of Schwab, Walker, and Reid that inherited the intellectual tradition of curriculum deliberation along with the practical reasoning process of Brown and Paolucci from a critical science perspective. The practical research problem was formulated as "What should be done to develop a Home Economics integrative curriculum?" To address this practical research problem, deliberation with deliberators of each small, medium, and large groups was processed for the development of integrative curriculum design plans. An initial proposal was developed from small group deliberation processes. An initial proposal was examined and an alternative plan was developed from medium group deliberation processes. An alternative plan and its consequence were re-examined from large group deliberation processes. The authors finalized a proposal organized on four valued ends of self-formation, intersubjectivity, social action, and life skills. A practical problem focused integrative curriculum was developed and proposed to pursue the four valued ends. The suggested final practical problem focused curriculum demonstrates the power of Home Economics to contribute to the advancement of individuals, families, and society as well as the practical empowerment of students.
