The construction of smart factories for government SMEs is not easy due to the lack of professional manpower. The use of retired professionals is a way to solve the problem to some extent and to solve the job problem of seniors by effectively utilizing social assets. This study examines the effectiveness of using Meister based on a survey of 195 companies participating in the Smart Meister Support Program. As a result, the better pre-participation readiness and the better management and coordination of change during the participation, the more significant influence was on Meister’s ability development and corporate performance. In particular, it was confirmed that Meister’s competence plays a role in both ‘pre-participation readiness and business performance’ and ‘between change management during participation and business performance’. In order to improve the performance of the smart meister business in the future, it is necessary to proactively promote the purpose and purpose of the business targeting companies that wish to participate in the business. In addition, it was found that it is necessary to support the development of change management in order to minimize the resistance to innovation during the project. It will be possible to enhance social competitiveness by resolving senior jobs and strengthening the competitiveness of SMEs by discovering and utilizing Meister, who is an expert among retirees.

The Indian peninsula is the region with the longest religious history in the world. Religion runs through the historical development process from ancient India to British India, and then to the partition between India and Pakistan. After the second world war, with the booming of national movement for emancipation, coupled with British India suffering from intensified confrontation between hindus and muslims, suzerain Britain introduced the ‘Mountbatten Plan’ to admit Muslim to establish a separated regime, which ultimately led to the construction of India nation-state in 1950, and the formation of Pakistan followed in 1956. Religious factors played an important role in the nation-state construction, as well as in various fields including politics, economy and so on after the establishment of the two countries. After a comparative analysis of the Hinduism’s role in the founding of India and that of Islam in the founding of Pakistan, this paper demonstrated the similarities and differences of religions’ roles in India and Pakistan. As a result, this paper found that religions were the ideological basis for both India and Pakistan to build a nation-state, but there are obvious differences in cohesion. Religious thoughts have influenced the national policies and administrative programs of the two countries in different degrees. Religions also more or less have strengthened the sense of national identity of each ethnic group in the two countries.

PURPOSES : For high driving performance and service life of cement concrete pavement, construction quality must be secured. The construction quality is to be measured after pavement construction, but in this case, it is difficult to improve construction quality. Therefore, it is necessary to develop a method for measuring and correcting the profile of the pavement and subbase so that the construction quality can be monitored immediately after construction. METHODS : The device that can measure the construction quality of cement concrete pavement has been developed. Through the experiment simulating the field situation, the profile of the pavement and subbase was measured and calibration method was developed. RESULTS : In the measured profile, an outlier by the sensor and noise by the sensor and vibration were measured, and a step-like profile was measured differently from the acture one. To remove outliers, the boxplot outlier removal method was applied by overlapping each data group. The noise were removed by a low pass filtering. And, it was calibrated to a profile similar to the acture one through the sampling interval adjustment and the weighted moving average method. CONCLUSIONS : The method that can measure and calibrate the profile that is almost identical to the actual one has been developed. Accordingly, it is expected that the performance of the pavement can be improved by accurately monitoring the construction quality immediately after construction.

Recently, the importance of project management has increased due to the scale and complexity of the construction projects. Therefore, this study conducted a survey on construction companies and related public institutions to verify the relationship between the role of the Project Management Office(PMO) and PM leadership for project performance. Based on this, the effect of the PMO role on the project performance was identified and the moderating effect of PM leadership was analyzed. As a result, first, the role of the PMO was found to have an influential on the project performance. Second, the PM leadership was verified to has a moderating effect in the relationship between the PMO role and the project performance. The purpose of this study is to analyze the influential of the role of PMO on project performance in the construction industry to suggest the necessity of PMO in the construction industry and the need to adopt PMO in large-scale construction projects and analyze the moderating effect of PM leadership on project performance.

The construction industry is considered to be a fatal accident industry, accounting for 28.5% of the total industrial accidents in 2017, as the number of industrial accidents in the construction industry has steadily increased over the past decade. So it is necessary to consider introducing Resilience Engineering, which is actively applied to risky industries around the world, to drastically reduce construction accidents. Although Resilience Engineering, which has emerged as the next-generation safety management centered on Hollnagel since the 2000s, claims the importance of strengthening Resilience abilities considering organizational structure and culture, most studies focus only on developing evaluation indicators. The purpose of this study is to analyze the impact of an organization's safety culture on its Resilience abilities in the construction industry. Specifically, it conducted empirical analysis on the impact of safety culture consisting of ‘communication, leadership and safety systems’ on the Resilience abilities(responding ability, monitoring ability, learning ability, anticipating ability), and the mediation relationship between leadership, communication, and safety system. The survey was conducted on construction workers, and an empirical analysis was conducted on the final 154 responses using SPSS 25 and Smart PLS 3. The results showed that the safety system had a significant impact on all Resilience Abilities, and communication had a significant impact on the remaining three except for anticipating ability among Resilience Abilities. On the other hand, leadership has been shown to have a significant impact on anticipating ability only. In the verifying of the mediation relationship between leadership, communication and safety systems, it was found that leadership affects all Resilience abilities by means of safety systems, but communication can only affect responding ability. This study has practical significance in that it suggests the need for policy-level efforts to introduce and apply Resilience Engineering and then expanded the effective safety management assessment of the construction industry in the future. Moreover, the academic implications are important in that the study attempted to expand the academic scope for a paradigm shift in the future as the safety culture has identified its impact on the Resilience abilities.

Recently, due to the aging of workers and the weakening of the labor base in the automobile industry, research on quality inspection methods through ICT(Information and Communication Technology) convergence is being actively conducted. A lot of research has already been done on the development of an automated system for quality inspection in the manufacturing process using image processing. However, there is a limit to detecting defects occurring in the automotive sunroof sealer application process, which is the subject of this study, only by image processing using a general camera. To solve this problem, this paper proposes a system construction method that collects image information using a infrared thermal imaging camera for the sunroof sealer application process and detects possible product defects based on the SVM(Support Vector Machine) algorithm. The proposed system construction method was actually tested and applied to auto parts makers equipped with the sunroof sealer application process, and as a result, the superiority, reliability, and field applicability of the proposed method were proven.

Since its construction in the late 14th century, Hanyangdoseong had been carried out three major repairs and reconstructions during the 500 years of the Joseon Dynasty. In addition to the large-scale construction, small-scale construction continued until King Gojong era. In particular, in the 18th century, systematic construction management was implemented by the craftsmen and the military participated in the renovation of Hanyangdoseong in earnest, and the construction methods also developed rapidly. In the early 18th century, new construction techniques were attempted in various sections of the reconstruction work, and gradually became a common technology for repairing Hanyangdoseong in the late 18th century. The purpose of this study is to examine the characteristics and period of changes in the 18th century's construction technique, when the rapid development of Hanyangdoseong took place. To this end, the excavation results related to Hanyangdoseong, the remaining city wall, and the inscribed stones were used to identify and demonstrate the characteristics and change of the construction method.

Young-dang(影堂) is a ritual pavilion where figures of a dedicated person is enshrined. According to literature, establishment of Young-dang architecture is thought to have the affinity with Buddhist tradition in the beginning of its history. A tradition of enshrining figure could be found especially in Buddhism. Until the mid Joseon dynasty, enshrining figure made of wood, clay and bronze was quite often at Young-dang. In Confucian ritual tradition, a pavilion where enshrining ancestor’s sprit tablet called Sadang(祠堂) or Myo(廟). In regarding portrait is a sort of figure, it has to be concerned with Buddhist ritual tradition. For this reaseon, Young-dang started to be distinguished from older aspect of existence in mid Joseon dynasty when the study of Confucian courtesy widely spread. It show the transformation process of Young-dang architecture from Buddhist tradition to Confucian tradition in J oseon dynasty.
