As global interests in the 4th Industrial Revolution have recently increased, it becomes critical for the construction industry to pro-actively cope with it. For effective actions, the construction industry needs to make active use of 4th Industrial Revolution technologies based on the up-to-date understanding of the trends of construction technology development employing the 4th Industrial Revolution technologies. The objective of the study is to investigate and identify key trends of ICT construction technology development over the last ten years based on Big Data Analytics. The study identifies eleven key trends and discusses that ICT construction technology development has not been as active as expected and software technologies have been less developed compared to hardware technologies.

As Crosby notes, the most companies spend 15 to 20% of their sales dollars on quality costs. Generally the most effective way to manage quality costs is to avoid having defects in the first place. In this paper we have studied about the repair(service) problem of domestic gas boiler within warranty period. We develop a system, which man could find the cause of the problem at an early stage and could devise a countermove to the problem under supposing that the service(repair) rate follows exponential distribution and the product is manufactured lot-for-lot continually. Using the developed early sensing system. it is expected to improve the reliability of the product, to save expenses of company and to improve customer's satisfaction. And the system will be expended to incorporate information technology, which can detect the repair rate automatically.

Muk-am Bae Guek-So's scholarly interests spanned a wide range of Confucian topics, but his most famous work is the Saryeganyo that is the book about the Study of the Li. Written in the 19th century, Saryeganyo was compiled with the clear purpose of exploring the relevance of the four ceremonial occasions of coming of age, wedding, funeral, and ancestral rites to changing times, while not losing sight of their core values and meaning. The fact that Bae was able to take these concerns of the Study of the Li and connect them to practical work was based on the assets and traditions about the Study of the Li that had been carried out and accumulated during the Joseon Dynasty. This book cites more relevant books and theories produced in Korea than in China. This is not only in terms of quantity, but also in terms of content. In this book, Bae actively reflects the achievements about the Study of the Li of the Joseon Dynasty, but in doing so, he maintains a very scholarly neutral attitude, i.e., he fairly reflects the research achievements of the Yeongnam school and the Giho school, which have enriched the Study of the Li of the Joseon Dynasty. The significance of Saryeganyo is that it reflects the trend of the 19th century, when the Study of the Li in the Joseon Dynasty moved from the stage of research to the stage of practice.

This study investigates the relationships among the presage, process, and product factors drawn from Biggs’ 3P model in one cyber university. Although previous studies thoroughly and clearly found the interrelationships among one or two student characteristics factors and learning outcomes, the current study aimed at extending those findings into holistically understanding the relationship among those factors by using learning analytics (educational data mining) approaches. The framework was drawn from Biggs’ 3P model; each P factor was examined to comprehend the relationship among the presage, process, and product factors. A total of 14,105 aggregated student data were collected to investigate the factors relating to student learning outcomes during the last two semesters-Fall, 2013, and Spring, 2014. Logit model from logistic sequential regression showed a sound predictability and model fit. The results showed that six student characteristics-academic discipline, gender, age, level of education, jobs, and year-and two learning process factors-content-to-access ratio and the numbers of participation in the course bulletins-were closely related to student learning outcomes. Specifically, student learning process factors were identified as the ones that mostly affected student learning outcomes. These findings implied that student learning outcomes were not simply predicted by one or two characteristics and learning processes, but rather were the complicated interaction of factors in a cyber university.

교수 학습 상황은 학습에 영향을 미치는 전조 요인, 학습 과정, 그리고 학습결과 요인으로 구성되며, 학습자 특성과 학습 과정에 영향을 미치는 요인들 간의 상호작 용에 따라 학습 결과가 달라진다. 본 연구에서는 학습자의 전공 특성을 학습 전조 요인으로 간주하고 학습자의 교수적 접근 방식에 대한 인식과 학습적 접근 방식을 과정 요인으로 설정하였다. 본 연구의 목적은 학습자의 전공, 교수적 접근 방식, 그 리고 학습적 접근 방식이 수업에 대한 유용성 인식과 만족도에 어떤 영향을 미치는 지를 분석하는데 있었다. 본 연구의 결과로 학습자의 전공 영역에 따라 수업 만족도에 차이가 있다는 점 을 알 수 있었다. 수업 과정에 있어서는 수업에 대한 학습자의 개념 변화를 촉진하 고자 하는 학습자 중심의 교수적 접근이 수업 만족도를 높이는데 기여할 수 있으며, 학습자 중심 접근을 할수록 학습자들은 학습 과정에 심층적으로 접근한다는 결론을 얻었다. Teaching and learning may be understood as relationships among presage, process, and product factors. These relationships may color the perceptions of teaching and learning experiences. This study has two major objectives. The first is to investigate the congruence or incongruence between approaches to teaching and approaches to learning. The second is to explore the presage and process factors affecting students’ perceptions of a course’s usefulness and their satisfaction with that course. In this study, 309 students from a Career Planning and Self-Development course voluntarily participated. The Approaches to Teaching Inventory-Revised (ATI-R) and Revised Study Process Questionnaire (R-SPQ-2F) were used to investigate students’ perceived approaches to teaching and to learning. To investigate the factors that affected students’ satisfaction and their perceptions of the course’s usefulness, Ordinal Logistic Regression (OLR) was used to explore the relationships among those factors. The results indicated that there was a strong congruence between students’ approaches to teaching and their approaches to learning. Interestingly, we found that students were more likely to adopt deep approaches to learning when they perceived that their instructors were adopting conceptual change/student-focused approaches to teaching. OLR analyses found that students’ perceptions of the course’s usefulness were closely related to their perceptions of the instructors’ conceptual change/student-focused approaches to teaching and soft/applied approaches to discipline. Students’ perceptions of the course’s usefulness were negatively related to their perceptions of the instructors’ information transmission/teacher-focused approaches to teaching. Students who majored in hard or applied science disciplines were more likely to perceive that the course was useful in planning their career paths. This study suggests that approaches to teaching and learning are relational and that the relationship between the approaches may have an impact on students’ satisfaction with the course and perceptions of its usefulness.

예학적 관점에서 본 학봉과 서애의 학술

Hakbong(Kim Sung-il) and Seoae(Ryu Sung-ryong) are Toegye(Yi Hwang)'s most a ccomplished and highly regarded stud ents. However, most of the existing studies on these two scholars focus on Theory of State Management or their activities during the Imjin War(Japanese Invasion of Korea). Despite the importance of their respective works of Yehak in the history of Joseon Yehak, there is a dearth of research on the subject of their works of Yehak. This paper is a preliminary work to examine the Yehak of Hakbong and Seoae on a scholarly level. At this point, it is believed that two things are necessary to review the Yehak of Hakbong and Seoae. Firstly, the Yehak of the two scholars have been studied by academics, mainly in the context of the book Sangryegojeung(喪禮考證), but it is time to expand the circle. For example, in relation to Hakbong's Yehak, it is necessary to examine his actions when he went to Japan as a messenger in 1590, and in relation to Seoae's Yehak, it is necessary to elucidate his problems by using his writings such as the Sangjangjileu(喪葬質疑). Secondly, it is necessary to reflectively reexamine the tendency of the research on Sangryegojeung(喪禮考證). In the meantime, Sangryegojeung(喪禮考證) have been d escribed a s works that utilised the contents of the Yegi(禮記) to compensate for the problems of the Garye(家禮). However, there are a number of things that make it hard to believe that this was the purpose of compiling the books. So in this paper, I look at the issue from a different angle. In other words, it is hypothesised that during the period of their parents' funerals, Hakbong and Seoae studied Yegi(禮記) intensively in order to understand the original meaning of the rituals, and organised their findings into the category of Garye(家禮). This paper is merely a preliminary attempt to raise some of the questions that need to be addressed in order to advance the study of the Yehak of Hakbong and Seoae. Fine-tuning these points is a challenge for the future.

Purpose: The purpose of this study is to explore the relationship between corporate entrepreneurship and organizational effectiveness among employees of medical institutions. In addition, we aim to investigate the mediating effect of motivation to participate in the In-house Innovation & Start-up Contest and the moderating effect of support from a dedicated organization. Methodology/Approach: A survey was conducted on participants in the 3rd in-house contest held in 2023 at Granum Sinapis Center of Seoul St. Mary's Hospital. A total of 122 people responded to the survey. The collected data were analyzed PLS-SEM(Partial Least Squares-Structural Equation Model) using SmartPLS 4.0 program. Findings: First, 'Corporate entrepreneurship' had an effect on 'Participation motivation in in-house contest'. Second, 'Corporate entrepreneurship' had an effect on 'Organizational Effectiveness'. Third, 'Participation motivation in in-house contest' mediated the relationship between 'Corporate entrepreneurship' and 'Organizational Effectiveness'. And last, 'Support from a dedicated organization' had no moderating effect on the relationship between 'Corporate entrepreneurship' and 'Organizational Effectiveness'. Practical Implications: Since the dedicated organization is in the early stages of operation, there may be no moderating effect on organizational effectiveness. If follow-up research is conducted after the dedicated organization's system has been supplemented, the moderating effect may appear differently.
