IT사례-RFID 시스템 도입 시 상대적 증가비용을 줄이는 것이 중요
유영석,Yu, Yeong-Seok 한국컴퓨터사용자협회 2006 The USERS Vol.47 No.-
RFID 인프라를 셋업하고 상품에 RFID 태그를 부착하는데 소요되는 비용이 천문학적인 숫자임에는 틀림없다. 따라서 상대적 증가 비용을 줄이는 것이 중요하다. 이에 따라 인삼제품을 선정했다. 100만원짜리 인삼(홍삼)에 RFID태그를 붙이는 것은 새우깡 봉지에 붙이는 것에 비해 확실히 체감비용이 다르기 때문이다.

In this study, the carbonized aggregate of light weight and high mechanical strength using sewage sludge was evaluated with changing carbonation variables of temperature, detention time and feed condition. Porosity and mechanical strength was simultaneously increased according to increase of carbonization temperature unexpectedly. Carbonization detention time above 1 hour nearly affect on the porosity, but mainly on mechanical strength of the carbonized aggregate in case of clay addition. On 900 ℃, porosity and mechanical strength was increased rapidly, but above 1000 ℃, porosity began to decrease. Clay addition was very effective on increase of mechanical strength following much loss in porosity. The carbonized aggregate manufactured at 900 ℃ adding 30 % clay in sewage sludge was higher a little in porosity and 3 times in mechanical strength than those at 700 ℃ not adding clay. Consequently, in manufacturing the carbonized aggregate having simultaneously high porosity and mechanical strength, it is desirable to have operational condition of 900 ~ 1000 ℃ temperature and 1 hour time, and clay addition within 30 % for further higher mechanical strength.

Purpose: The purpose of this study is to identify the impact of conflicts and cooperation on project performance in the nuclear power plant construction project, thus contributing to the successful performance of project participants and the achievement of project objectives. Methods: This study used a method of conducting a survey of participants in the nuclear power plant construction project and verifying the hypothesis statistically. Results: The results of this study are as follows; First, role conflicts and relationship conflicts have negative effects on collaboration. Second, role conflicts have a negative effects on project performance, but conflict in relation has no significant effects on project performance. Third, collaboration has a positive effects on project performance. Finally, the communication quality in the relationship between conflict and collaboration has been shown to have a Moderated effect. Conclusion: In order to achieve the goal in the nuclear power plant construction project, the level of collaboration should be improved based on conflict management among project participants.
