CM기업의 서비스 품질 측정을 위한 모델개발에 관한 연구
정원민,김한수 대한건축학회 2007 大韓建築學會論文集 : 構造系 Vol.23 No.7
The CM(Construction Management) market has been growing steadily since 2000, but there are a lot of obstructing factors. Recently, many questions have been raised over the level of construction managers’ technique, the appropriateness and efficiency of CM, and the its performance. Through the interview of CM companies’ top management, it figured out that top 5 CM companies in domestic are not evaluating CM service quality effectively. They are evaluating customers’ satisfaction rate, which is very partial. In this respect, evaluating CM service quality is a very important issue not only to acquire a better position in unlimited competence markets but also to survive. The objective of this study is to present a service quality evaluating model which can be adopted to CM companies. This study contributes not only to presenting an evaluating model of CM service quality, but also to understanding clients’ requirements.

This study was carried out to investigate the residual characteristics of mixed fungicide of carbendazim and diethofencarb among Schizandra chinensis Baillon to use it as primary data for safe use guideline. The pesticide (carbendazim + diethofencarb wettable powder, 25% + 25%) 1,000-fold dilution was set on different pre-harvest treatment days in the groups, and samples were collected after foliar spraying three times with an amount of 3.94 - 3.97 L/10 m2. The collected samples were processed through a hot air drying process, and pesticide residues in fresh samples from the treatment closest to the harvest date were analyzed to calculate the processing factor of the test pesticide. The method limit of detection (MLOD) was 0.01 mg/kg for two pesticides in dried or fresh samples. The average recoveries of carbendazim were 82.2 - 101.9% and 96.4 - 109.7% in dried and fresh samples, respectively, and those of diethofencarb were 98.8 - 103.2% and 95.7 - 101.5%, respectively. Residual amounts of carbendazim were 2.40 - 46.04 mg/kg in dried samples and 7.30 - 7.88 mg/kg in fresh samples. Residual amounts of diethofencarb were calculated to be 0.29 - 24.56 mg/kg in dried samples and 3.80 - 4.31 mg/kg in fresh samples. The processing factors of carbendazim and diethofencarb among Schizandra chinensis Baillon calculated using the average residual amount before and after drying were 5.76 and 5.54, respectively. The %ADIs of carbendazim and diethofencarb in chizandra chinensis Baillon were less than 0.0243% and 0.0009%, respectively.
