일반적으로 건물이나 산업현장에 설치되는 항온항습기 및 공조 장치 등은 외기의 온도나 습도와 관계없이 관리자가 최초 설정한 값을 수동으로 변경시키지 않는 한 항온항습 또는 냉$\cdot$난방 기간중에 연중 또는 수개월 간 항상 일정한 실내 온$\cdot$습도를 유지하기 위해 많은 에너지를 소모하고 있다. 이러한 문제점에 착안하여 비교시험을 통한 실증시험을 수행한 이코노 공조기는 본문과 같은 여러 가지 기능들을 자동으로 수행하게 함으로써 공조부하 절감을 통하여 궁극적으로 에너지 절감을 이룰 수 있도록 제작된 기기이다.

제조 기업이 글로벌 경쟁 환경 속에서 생존하고 발전하는 데에는 그 기업의 부단한 생산혁신을 통하여 품질 및 가격, 납기에 대한 획기적인 개선노력으로 원가경쟁력을 갖추어야만 한다. 식스시그마를 비롯한 많은 품질경영혁신 도구가 상존하고 있지만 대기업에 반해 상대적으로 기업규모와 경영기반구조가 취약한 중소 제조기업의 경우에는 해당기업의 혁신도구를 찾아 적용하기에 매우 어렵다 할 수 있을 것이다. 그리하여, 필자가 이러한 현실을 감안하여 산업현장에서 실증적으로 지도하고 참여하였던 사례를 연구 검토함으로써 제조기업의 품질경쟁력을 향상시키기 위한 대안의 하나로써 제시하고자 한다.

In this study, seven companies(A~G) designated as new construction technology selected and evaluated KS F 2622: Method of test for performance evaluation of membrane roofing systems that are similar to field application conditions. As a result of the test, it was confirmed that although all test specimens exceeded KS standards in the basic physical, it was difficult to obtain field quality performance in weak areas such as joints and vertical parts of the adhesive coating method in water-tightness, sagging resistance, swelling resistance tests except for fatigue(crack behavior) tests.

This study was intended to analyze the effects of Entrepreneurship on manufacturing(G-automobile) employees' Organizational Culture and Job satisfaction. A proposed model based on previous research was empirically tested via SPSS 25.0 using 349 valid samples collected from current employees of G-automobile Enterprises in Chang Won. The results of the empirical analysis are summarized as follows. First, Entrepreneurship(Innovativeness, Proactiveness, Risk-taking) had direct effects on Job satisfaction. Second, Entrepreneurship(Innovative, Enterprising, Risk-sensitive) had direct effects on Organizational Culture. Third, as a result of analyzing the effect of Organizational Culture on Job satisfaction, it was found that Organizational Culture(Development Culture, Rational Culture) had a significant positive(+) effect on Job satisfaction. The results of this empirical analysis are considered to be related to the rigid organizational culture of automobile manufacturing companies with many male-oriented field workers. In the future, research involving other automobile manufacturers is expected to be needed.

Due to the recent increase in various problems from underground development in urbanized areas, accurate underground facility information management is highly needed. Therefore, in this study, in order to utilize the Integration Map of Underground Goespatial Information in real time on-site, the function of comparing the mutual location of the GPR (Ground Penetration Radar) sensing data and the Integration Map of Underground Goespatial Information, and function of analyze underground facilities, and function of converting surveying data into a shape file through position correction & attribute editing in a 3D space, and the function of submitting the shape file to the Integration Map of Underground Goespatial Information mobile center was defined and developed as a program. In addition, for the on-site application test of the development program, scenarios used at the underground facility real-time survey site and GPR exploration site were derived, and four sites in Seoul were tested to confirm that the use scenario worked properly. Through this, the on-site utilization of the program developed in this study could be confirmed, and it would contribute to the confirmation of the quality of Shape-file and the "update automation" of "Integration Map of Underground Goespatial Information". In addition, it is expected that the development program will be further applied to the Underground Facility Map's Accuracy Improvement Diffusion Project' promoted by the MOLIT (Ministry of Land, Infrastructure, and Transport).

As recent buildings have been enlarged and free-formed, it is hard to represent three-dimensional buildings with two-dimensional drawings and identify design errors, construction errors, difference of construction quantity and construction cost, clash with columns, beams, pipe machinery, and so on. In order to overcome the limitations, BIM(Building Information Modeling) has been used in construction industry. However, BIM in the construction site is not fully facilitated after practical implementation in process control including training, evaluation and analysis of the process. Therefore, in this study, the effect of BIM applied in the construction site is analyzed empirically throughout the survey at the construction site in accordance with the training, evaluation, and implementation of BIM.

This empirical study focused on examining the relationship between transactional transformational leadership style and power of construction project manager and the organizational effectiveness, respectively, and the moderating role of power between leadership and the organizational effectiveness. A 790 numbers useful questionnaires were obtained from the stuffs working at the construction sites excluding project managers. Internal consistency test using Cronbach's ${\alpha}$ and confirmatory factor analysis were conducted for the reliability and validity of the scales respectively. And cluster analysis and multivariate analysis of variance (MANOVA) were conducted to test the hypotheses. The results and implications are as follows. First, the leadership styles of project managers influence positively the subordinates' job satisfaction but not organizational commitment in construction project. Second, the power styles of project managers influence positively the subordinates' job satisfaction and organizational commitment. Third, the leadership styles of the project managers influence positively the subordinates' job satisfaction and organizational commitment by the power moderating role. The implication of this result is important because of the fact that the transformational leadership can be useful even in the construction projects. And the moderating role of the project manage's power suggests.

The earthwork is a core process of all constructions, and compaction measurement of earthwork play an important role in improving productivity. The analog tests such as Plate Bearing Test and Sand-cone occupy current compaction measurement techniques. Due to advanced 4th Industrial Revolution, research on analog tests combined smart construction technology are actively conducted. DCPT (Dynamic Cone penetration Test), simpler and faster than conventional tests, has recently on rise. However, it is also an analog that measures data manually and has several disadvantages such as history management and data verification. The IoT-based DCPT system developed in this study combines digital wire sensors, mobile phones, and Bluetooth with conventional DCPT. Compare to conventional test methods, IoT-based DCPT has advantages such as performance time, single-person measurement, low cost, mobile-based management, and real-time data verification. In addition, a test bed was built to verify IoT-based DCPT. The test bed was built under similar conditions to the actual earthworks site through roller equipment. DCPT data obtained from 322 stations. As a result, IoT-based DCPT showed good performance, and the test bed was also showed stable results as the compaction was carried out.
