  • Normative theory suggests that control systems should be designed to complement management's objectives and strategies. However, few empirical studies have focused on how control systems have been modified to complement new manufacturing techniques, such as zero-defect strategy. The major purpose of this study is to examine the effects of the attributes of quality strategy and control system on performance. The previous studies have subdivided quality strategy into the ECL(economic conformance level) and ZD(zero-defect) strategy. To accomplish the purpose, this study empirically analysed the data based on the questionnaires from manufacturing department personnel of 67 Korean companies. The major results are as follows. The companies that had implemented the ZD strategy and its control system outperformed the companies that had implemented ECL strategy. Also, the ZD strategy differs from ECL strategy in control system, the criteria of performance evaluation and feedback frequence variable. There is no difference in quality performance monitoring and communication variable. From this results, although many companies have strived for continuous improvement of quality, it was restricted in improvement activities that dont's required much investment cost, quality performance monitoring and communication.

  • The global economic recession caused a great change of the labor environment such as restructurings and unstable employment. This facts brought about an increase in sense of rivalry, over workload, job uncertainty and lowering of self-confidence. Due to the fact that the work process and employing system in construction field is little differ from normal industries, especially, labors working in construction field are much exposed to the job stress. On this study, we survey construction-field labors and made an analysis of the gathered data through the statistic method to reveal what kind of job-stress factors influence on the defects of construction works. As the result, we investigated the truth of the induction factors which cause the job-stress in costruction field and proposed an alternative plan for an effective job-stress management which make the defect rate low.

  • The type and proportion of construction work varies depending on the stage of progress, and the frequency of inspection and defect occurrences are different. If it is determined to be defective after the inspection, a delay may occur, and additional manpower and resources are required. Therefore, it is necessary to prevent these risks by classifying, deriving, and managing key management woks according to the progress. This study aims to contribute to the efficiency of the supervisor's inspection work by identifying the types of construction that should be managed intensively for each construction progress and deriving the time when defects occur frequently in each construction type.

  • Although lots of safety inspection and precision safety diagnosis have been conducted on concrete retaining wall, there is no comprehensive analysis on the basis of the accumulated data associated with the statistic. Especially, the concentrated management is necessary on the evaluation items that cause critical damages for the efficient performance. In this regard, this study conducted a correlation analysis between the 18 condition evaluation items and defect index for the concrete retaining wall as well as how each item affects the final defect index as much as in the manual. As a result, correlation coefficient between sliding and overturning was 0.601, which means that they have a strong correlation, and the most influential item on defect index is the condition of drainage that scored the 0.750 correlation coefficient. In addition, as a result of regression analysis, the condition of drainage with the 0.683 correlation coefficient has a strong correlation with the defect index. If the condition evaluation items are integrated or readjusted based on the results of the statistical analysis in this study, the more efficient and accurate maintenance will be possible.

  • Eighteen infants with a large ventricular septal defect[VSD] underwent primary surgical repair from January 1986 to December 1992. Operation was done because of failure to thrive, medically intractable heart failure, recurrent pneumonia, increased pulmonary vascular resistance[PVR]. Four patients[22.2%] died in the early postoperative period. Relief of heart failure and normalization of growth and weight gain was evident in all survivor. There was no late postoperative death. The results of primary surgical repair of VSD in infancy are compared with those of palliative pulmonary artery banding[PAB] and of VSD closure after PAB. Twenty-seven patients with isolated VSD or with VSD associated with atrial septal defect, patent ductus arteriosus, or coarctation of the aorta underwent initial palliative PAB. There were 3 early postoperative deaths[11.1%]. Severe elevation of PVR persisted in two patients. Closure of VSD and pulmonary artery debanding was done in twenty patients, with 2 early postoperative deaths[10.0%]. Placement of the PAB too close to the pulmonary annulus necessitated trasannular patching in one patient, but any problem caused by migration of the band was not developed. It is concluded that primary surgical repair of VSD in infancy is reasonable and that PAB is indicated only for those patients less than 6 months old with a complicated defect or in an emergency situation.

  • It is required to study systematical on the concrete quality management to extend structure life because rebuilding effect is reducing under present condition of large sized and high stories structure. Concrete, which shows its intensity by hydrating action and a big change in quality according to hot weather and temperature, produces a lot of qualify problem under hot and cold weather Because of each specification and construction plan which does not have basic standard on site, concrete's quality is irregular and makes some defect. As a result, Daegu is turned out to be the longest area after investigating application period and days focused on 8 cities weather information about relationship between hot weather circumstance and construction environment. Therefore, we first surveyed the concrete material in the region and found out the problem of quality nanagement. Then figure out the way of solution. Moreover, we integrated concrete material quality management, which is applied differently to each site, to have equal quality and to reduce defect from construction site. And then, based on various test of construction condition and analysis of quality management item, we suggest effective concrete quality management to make concrete material construction standard guide and plan under hot weather.

  • 수년에 걸쳐 장기적으로 사업을 추진해야 하는 대형건설공사를 위해서는 단년도에 편성된 예산의 한도내에서 공사를 차수별로 계약체결하는 장기계속공사계약과 전체공사에 대한 예산을 편성해 두고 연차적으로 집행해 나가는 계속비사업계약이 있다. 장기계속공사계약의 경우 매년도 예산편성에 따라 공사를 진행하게 되므로 최초 예산을 산출할 때 전체 사업기간을 예상할 수 없다. 또한 장기계속공사계약과 관련해서는 하자책임과 관련된 법령, 계약이행과 관련된 법령이 체계적으로 정립되어 있지 못하고 있다. 그러므로 실제 건설현장에서는 장기계속공사계약과 관련하여 하자책임이나 계약의 이행과 관련하여 많은 문제점이 발생되고 있다. 이에 본 연구에서는 장기계속공사계약의 효율적인 운영을 위해 다음과 같은 개선방향을 제시하였다. 첫째, 하자담보책임은 법적책임이므로 시행령이 아닌 법에 명시하여야 한다. 둘째, 장기계속공사에서 차수별 계약당사자가 달라질 경우 시행령에서 특약을 정할 수 있도록 명시해야 한다. 셋째, 장기계속공사의 공기연장으로 인한 간접비가 발생될 경우 총사업비관리지침의 예비비항목을 활용할 수 있도록 해야 한다. 넷째, 공사계약일반조건의 경우 손해보험의 가입, 검사, 인수, 하자보수 및 하자검사와 관련된 조항을 보완해야 한다.
