It is very important for performance of information system that we make an effort to raise user's satisfaction by continuously grasping user's requirement by evaluation of PMIS based on ASP service quality and reflecting this to information system. However, It is lack that developments of suitable evaluation index of PMIS based on ASP service quality. Hereupon, In this study, we propose the evaluation indicators. First, The evaluation area is classified by form the foundation of D & M IS Success Model (2003); system quality, information quality, service quality. Second, The detail evaluation item which include considerations which are gotten through investigation of the construction industry and PMIS based on ASP is grouping by form the foundation SERVQUAL which is a service quality evaluation tool proposed PZB(1988). It is suitable to evaluate PMIS based on ASP service quality in construction industry and able to evaluate various aspects.

This paper provides the results from evaluating the stiffness of Hi-Form joint by an experiment and the system identification method using the dynamic modal data, and the reasonable modeling method of Hi-Form joint which is proposed for improved stair construction recently. Based on the crack pattern and load-displacement relationship and the damage distribution, it can be judged that Hi-Form joint can't fully transfer the forces between the elements linked, and we propose that the joint is modeled as a element which have a stiffness with 50% decrease.

Purpose: In Korea, buildings make up 20.5% (2012) of the gross national energy consumption, so they are a major target for greenhouse gas reduction. In particular, energy consumption in multihousing represents approximately 32.6% of the entire building sector. With improving energy performance being the focus, efforts are continuously being made to reinforce standards and systems in greenhouse gas reduction. This study investigated the current status of multihousing in Korea in terms of energy performance as described in the performance evaluation reports submitted (to an institution that specializes in reviewing the performance evaluation of green homes) based on the construction criteria and performance codes for green homes and examined if the evaluation criteria using related methodologies were appropriate. The results will provide helpful information for reviewing the future directions of operations and amendments to the systems. Method: The overall characteristics of the system were examined using the evaluation methodologies (and current state of revisions) of the performance codes for green homes and comparing them with similar systems. Also, the current state of application and energy performance (conducted according to the evaluation methodologies) were compared by the evaluation institution for multihousing neighborhoods that were assessed for five years from 2010 to 2014. Result: It has been confirmed that the performance codes for green homes are different from other similar systems in evaluating performances of multihousing in that they allow both quantitative and qualitative methods of evaluation, and they consider both energy and sustainability simultaneously in the evaluation. Furthermore, regarding the adoption rate of the forms for the two evaluation methods (Form 1 - quantitative and Form 2 - qualitative), the rate preferring Form 2 increased gradually in time to reach 55.3% in 2014. In analyzing the rate of overall energy reduction (submitted in Form 1) and the coefficient of thermal transmission for each part (submitted in Form 2), it was observed that the deviation between the performance submitted and the criteria decreased in line with the level of reinforcement.

The separation and determination method of racemic isomers of flurbiprofen in urine samples have been investigated using column switching- HPLC, which include the sample treatment and concentration column. The optical rotation of two isomers separated were measured to identify d-form and l-form. The calibration curves are liear in the ranges of $0.11-5.4{\mu}g/mL$ for both d-form and l-form. The detection limits were $0.031{\mu}g/mL$ for l-isomes and $0.027{\mu}g/mL$ for d-isomer. The coefficients of variation of intra-day and inter-day precision of this method were about 1.8%. The present method was apllied to determine the concentration of racemic isomers in urine sample from human eating the drug.

This study is about quality test of parmament form for practical application. Nowdays domestic building market in the face of 3D, in addition to construction cost increase, materials lack problems and opening a building market to foreign countries, is trying to find out the efficient ways of overcoming these problems. So the efficiacy of form work to technical improvement will contribute a practical permanent form in field through quality test of permmament form. In this paper, we examined the total system of form erections and evaluated the structural permament of columns and beams.

The research thesis has been intended to make a comparative analysis on the basic bodice pattern and basic skirt pattern changing on the basis of setting waist line of dress form in an effort to set reasonable standards in selecting the standard lines of drees form. The thesis has made the wearing evaluation by producing the sample of upper and lower dress based on A pattern and B pattern. In details, A pattern functions to keep waist line flatly down from lateral waist-right to posterior waist in a little curved state, paralleling bust line and hipline with waistline. And, B pattern functions to keep waistline, bust line and hipline horizontal paralleling with ground surface. SPSS win 10.1 program was used for the analysis of evaluation and t-test. The result is as follows: For basic bodice-front of upper dress, A and B patterns have made little significant difference. With regard to basic bodice-back, B pattern has got the higher evaluation than A pattern, in the pattern stability and appearance. For basic skirt pattern, A pattern has got the lower evaluation in the aspect of total back appearance, back dart, hip line, and waist line, and front drape. Basic bodice pattern of A pattern, which takes on the different horizontal standard lines of dress form depending on the selection of waistline, and basic skirt pattern has scored less in terms of pattern stability and appearance.

In current coordinate measuring machine practice, there are no commonly accepted sample sizes for estimating form errors which have a statistical confidence. Practically, sample size planning is important for the geometrical tolerance inspection using a coordinate measuring machine. We determine and validate appropriate sample sizes for form error estimation. Also, we develop form error estimation methods with certain confidence levels based on the obtained sample sizes in various form errors: straightness, flatness, circularity, and cylindericity.
