As programmable logic controllers (PLC) have become more cost-effective and more powerful, they have been used in a large number of industrial applications. A model plant application is used to enhance the discussion further and to highlight the abilities of today's modern, more powerful, PLC in hopper and mixing system. Local area networks(LAN) are recently developed solution to the problem and appear to provide a communications network for true factory automation. So PC provide low-cost graphic display, data collection, and management analysis. An example of a control in industrial process, communication method between PLC and PC is presented.

The purpose of this study was to investigate analyze the level and method of weight reduction on weight classification athletes including 36 Judo players, 10 Wrestling players, 12 Boxing players, and 21 Taekwondo players(total number of 79) The results of this study are as follows; 1. Each athletic weight reduction was displayed the largest amount of weight reduction in wrestling players was shown as 5.40±0.52㎏. Total weight reduction was displayed as the highest reduction (46.83% in the level of less2∼5㎏). In the level of over 5㎏, the percentage of 24.05 was shown. Also Judo and Wrestling players showed significant(p<.05) difference in over weights difference. 2. The method of weight reduction was displayed in such order: 1) exercise + sauna+ no food, 2) exercise only, 3) exercise +no food and 4) exercise +sauna respectively, the rank of the percentage showed as 54.43%, 20.25%, 15.18%, 10.12%,however, there is no weight reduction by using drugs. As the results, It is difficult to apply athletes weight reduction rate for each individual, otherwise it should be concerned on level up in the weight reduction level of over 5㎏. Futhermore, the purpose of weights reduction should focus on the maintenance of low body fat.

The purpose of this study is to identify the effects on rational consumption behavior of economic instruction using simulation learning in elementary school. The following hypothesis was set: Economic instruction using simulation learning will change elementary school children into rational consumers. And three sub-hypotheses were set: Sub-hypothesis 1 : Elementary school children will manage their pocket money strategically after economic instruction using simulation learning. Sub-hypothesis 2 : Elementary school children will do practical purchase after economic instruction using simulation learning. Sub-hypothesis 3 : Elementary school children use their things effectively after economic instruction using simulation learning. An experiment was implemented with 38 sixth-graders from S Elementary School in Gongju, The procedures of our experiment included pre-test, experimental treatment, and post-test in order. Three sub-hypotheses were accepted after data of pre-test and post-test were analysed statistically. Therefore the results of this study suggest that economic instruction using simulation learning is a effective economic education method to change elementary school children into rational consumers. 본 연구는 시뮬레이션 학습을 활용한 경제수업이 초등학생들의 합리적 소비 행동에 영향을 미치는 지를 알아보기 위한 것이다. 이를 위해 충청남도 공주시에 소재한 S초등학교 6학년 1개 학급 38명을 실험집단으로 선정하였다. 실험집단을 대상으로 일반적인 용돈사용 실태와 합리적 소비 행동 등에 대하여 사전조사를 실시하였고, 시뮬레이션 학습이 적용된 수업안을 바탕으로 16차시의 경제수업을 실시하였으며, 수업 후 사전검사지와 동형의 사후검사를 실시하여 사전검사와 사후검사에 대하여 통계 분석하였다. 그 결과, 시뮬레이션 학습을 활용한 경제수업이 초등학생들의 소비 행동을 합리적으로 변화시키는 데 효과적임을 알 수 있었다. 이를 보다 세부적으로 분석해 결과, 첫째, 시뮬레이션 학습을 활용한 경제수업은 초등학생들이 계획적인 소비를 하는 데 영향을 미치는 것으로 나타났다. 둘째, 시뮬레이션 학습을 활용한 경제수업은 초등학생들이 실용적 구매를 하는 데 영향을 미치는 것으로 나타났다. 셋째, 시뮬레이션 학습을 활용한 경제수업은 구매한 물건을 잘 관리하고 아껴쓰도록 하는 데 영향을 미치는 것으로 나타났다.
