A automatic production system was developed for high productivity and safety. The semi-progressive die was unfavorable for more productivity, safety, material extravagance and incongruent high-speed production. Developed progressive die is suitable for the high production and guarantee triple production by acceptance of three array type for automobile adjust plate. We adopt Pro-$Engineer{\circledr}$ for three dimensional computer aided design suitable for the disassembly and assembly evaluation. The conclusion of this study is as follow. First, press die parts solid modeling system is built by using Pro-$Engineer{\circledr}$ through this research and verified allowable tolerance and possibility of assembly and disassembly of parts. Therefore we can reduce die manufacturing time and cost. Second, We produce 1000 units pet hot coil 1ton by traditional method, but we can acomplish material saving effect about 12% as 120 units in case of new progressive die. Fourth, we acomplished manufacturing cost curtailment effect more than 20% in comparison with traditional method.

The objective of this study is to develop education programs for cultivating smart aquaculture experts through a education demand survey of industries, high school students, university (graduate) students and field workers. The industry demand analysis was conducted as an in-depth interview on representives from seven companies. Education demand surveys were conducted on 96 students and field workers in the Jeonnam region. Results on the demand survey were analyzed using frequency analysis and cross-analysis. The company representatives responded that they want to participated in internship and retraining programs to proactively secure manpowers with convergence capabilities about smart aquaculture. Seven companies preferred manpowers with basic competencies on ICT (Information and Communications Technologies) or aquaculture. The most respondents in the demand survey want to participate in the education program for experience on advanced technology, self-development and enhancement of work capability. On the other hand, some respondents said that the education is time-consuming and that the education program does not fit their level. Thus, the education program should be developed in a way to minimize the spatial and temporal limitations of education targets and to improve understanding of non-majors by reflecting the demands of human resources in the industrial field.

The objective of this research is to provide an understanding of how coffee production has been taking place since the coffee industry in Vietnam came out in the global market after Doi Moi. Current research tries to understand how the local households of coffee production adjusts to their production process according to internal and external influences. In order to explore coffee production in the level of local and household units, the structure of coffee production in Dak Lak is first explored in terms of production and sales with the cases from two communes. The examination reveals that general characteristics of coffee crops that would reflect coffee production structure. Further, this study interrogates farmers' response to reflect some direct and indirect influences in recent years. That shows how the elements of coffee production in global market induce a change of coffee production in the study area. Those aspects are analyzed in relation to yearly coffee price fluctuation and diversification. Also, this research explores some of farmers' responses toward the environmental friendly coffee production.

Genetics has played a pivotal role in increasing the world food production through revolutions in plant and animal sciences. Though the attention on fisheries has been inadequate but the growing importance of modern genetic manipulations and biotechnological innovations to aquaculture has been realized. Recent advances in fish genetics and molecular biology have provided a suite of useful techniques, which have several applications in aquaculture. This paper reviews the advancement in the applications of selection, hybridization, chromosome engineering, sex control, gene transfer and molecular technologies for enhanced aquaculture productivity.

In this study, a new laval type nozzle was designed and manufactured. Using this nozzle tin powder was produced in close coupled system by using nitrogen gas at different operating conditions. The results showed that the increasing the gas pressure up to 1.47 MPa reduced the mean powder size down to 11.39 microns with a gas/melt mass flow rate ratio of 2.0. Powders are spherical in shape and have smooth surfaces.

This study developed an experience-based economic education program and examined its effects on young children's economic concepts and purchasing behavior. Subjects were 60 5-year-old kindergarteners assigned to an experimental or a control group. Instruments for pre- and post-tests were the Economic Concept Task (Laney, 1995) and the Purchasing Behavior Task (Jang, 2004). Experimental group children participated in the economic education program for 5 weeks; control group children listened to economic stories. Differences between pre- and post-test in the experimental group showed that the economic education program was effective in development of concepts of scarcity, opportunity cost, resource/production, goods/services, and complements/substitutes. Children's purchasing behavior changed partially after application of the program.

Recognition reactions about business area activities of business ethics measurement before and after business ethics educations are as follows: 1. Relativism average in production ethics after education shows the high rates, and deontological theory average shows the low levels. These facts show that period characteristics to respect value diversities are reflected. 2. The high average of justice theory, utilitarianism, relativism in distribution ethics before and after education reflects that fair competitions and multitude happiness are preferred, and situation adaptations about the environment changes are preferred. The low average of egoism and justice theory shows that value systems of minorities are not preferred. 3. The high average of relativism in advertisement ethics before and after education reflects the period characteristics to respect value diversities, and low egoism average shows that ethics standards of examine objects are high. 4. Egoism average in selling ethics before education is high, but this average after education is low. These reflect the fact that business ethics educations are efficient.

This study aims to inspect national security consciousness of marriage migrant women, and to figure out factors which affect on awareness of national security. Based on this, this study also suggests a way to build up national security of marriage migrant women. As the result of the factors on security situation, there were several things which are necessity of education, trust in the army and government, positivity toward North Korea and so on, while necessity of education, trust in the army and government, national pride and positivity toward North Korea were on the awareness of national security. There are three ways of building up national security consciousness of marriage migrant women. First, security education is needed to be in the social adjustment program of marriage migrant women. Secondly, concern on security is required to them. Third, a necessity of production on security education material is demanded for marriage migrant women.
