Total Project Cost Management System(TPCMS) was introduced with the purpose of increasing the efficiency of cost control for public construction project in 1994. In this paper, general perception of participants of the public construction project on the TPCMS was examined, and the problems in implementing the TPCMS was figured out through expert interviews and survey. Then better ways to implement the system were drawn based on the problems. To effectively manage the cost of public construction project, basically project cost should be estimated accurately in planning stage and managed based on it to have a project complete within the budget. In addition, the cost need to be managed in more systematic ways in terms of data collection and analysis, and the autonomy in managing the project cost given to the project owner needs to be expanded. Most of all, proper budget should be provided to prevent a project from delay through setting the priority of projects and proper budget allocation based on the priority.

Purpose: The purpose of this study is to provide reference points for the improvement work of churches' convenience facilities for the elderly. To do this, the study generates survey results, showing that the perception to significance of churches' convenience facilities is different among survey constituents. Method: The survey method was utilized. The study population for survey includes the aged believer over 65 years old, pastors, and architecture and/or interior design experts. The questionnaire was devised while consulting existing regulations regarding convenience facilities in general. Results: It is found that the perception to significance of installation standards for convenience facilities is different among survey constituents. Specifically, while the older believer group is perceived that installation standards for the small group meeting room of 'other facility' is comparatively more important, the pastor group and the expert group perceive that the 'intermediate facility' and 'inner facility' are more important. Implications: Participants involved in an improvement project of churches' convenience facilities may have a different perception about their importance due mainly to the degree of usage and the difference of perspectives. This study, therefore, can be used as a reference point for prioritizing improvement works of churches' convenience facilities for the elderly.

Current environment in civil and construction industry has changed to actively adopt construction management (CM) in various areas. While it is found that exemplary CM projects have been carried out in many civil engineering sectors, concrete system framework has not been suggested due to ambiguous boundary between CM and supervision system, unclear perception of CM's role, and inexperienced organization and regime. This paper investigated the challenges faced in civil and construction industry, and analyzed the strategy that could improve the current immature CM system by conducting questionnaire survey from experts in various construction sectors. The results could provide valuable information that can involve diverse opinions and view points in project participants.

IT system in supply chain management(hereafter, SCM) has been regarded as one of competitive advantage to win over competing supply chain. SCM participants rush to adopt IT system to be agile for changing environment. Companies expect the improvement of the process integration over the supply chain, which enhance the overall SCM performance. IT system has been considered to influence on effective communication over the wall of firm boundaries. But, the profitability or the effectiveness of IT investment are controversial. This study try to reemphasize the importance of IT system considering the differences of processes, and the influences on the collaboration of supply chain participants. We want to know the perception level of functional managers for the importances, usages, and contributions of IT system in manufacturing sector. Also, we compare the different perception for collaborative SCM among supplier, buyer, and employees of buyer, and try to understand the context in which the IT investment acceptance occurs. We collected 297 responses(199 from line process and 98 from project process respectively). Results show that the importances, usages, and contributions of IT system are higher in the line process than in the project process.

The ability to use information technology has become increasingly important as technological advances continue to sweep through the computing world, and education for improving computational thinking has become globally instituted. In South Korea, informatics subjects have been modified in the 2015 curriculum and are now compulsory in primary and secondary education. However, despite substantial financial investment and numerous studies promoting informatics education, there continues to be a serious lack of pre-service teachers capable of teaching computational thinking. This study investigated pre-service teacher programming education using App Inventor, their perceptions of App Inventor, and how use of the program affected teacher problem-solving abilities and self-efficacy. In the pre-test, the control group and experimental group showed no statistically significant difference; however, the post-test revealed that the two groups showed statistically significant differences in problem-solving skills and self-efficacy. The participants initially showed interest in using App Inventor; however, after practice-teaching and project-based learning, the participants demonstrated a growing negativity toward the program when they made errors and the functional limits of App Inventor became apparent. Although most participants stated that they would not use App Inventor in their classes, the positive statistically significant differences in problem-solving skills and self-efficacy indicate that this study could be utilized as a basis for building a teaching-learning program using App Inventor and creating an educational plan for teaching computational thinking.

This study was executed by means of "user participatory design method", as a part of the public facility remodelling project supervised by the Seoul Municipality. This study aimed to complement and improve the methodology through reviewing the whole process of participatory design implementation and examining closely whether the activities, design methods and tools that have been applied at each stage were helpful to reflect the users' demands successfully. Given all of those, it implies; first, it is very meaningful that public facility remodelling project by "user participatory design" leads the ordinary users to have direct opportunity to participate in the public business and to change their perception of the restroom environment in school. Second, it is necessary to integrate the roles of the facilitator and the architect from the beginning stage of the process, which makes it feasible to reflect the users' needs to the final stage. Third, it is required to modify the design tools that enable non-professional participants to understand their tasks and to perform them effectively at the stage of decision making.

Daycare center is an important space for children's mental, physical and social development. Each space of daycare center should be designed and constructed considering interests of end-users such as children and teachers. However, insufficient related guidelines and standardized design and construction of daycare center to moderate potential risks of each space. This arises from the difference in perception of each space between end-users (head and sub teachers) and construction experts (designers and contractors). Therefore, research framework was developed for analyzing the factors of perception differences of each space in daycare center between these groups applied traditional and modified Importance-Performance Analysis (IPA). By comparing risk perception between end-users and experts in two methods, it can be support as construction guide for daycare center in the future and will help minimize conflicts in construction among stakeholders. Moreover, it was found that traditional IPA is comfortable to catch prior project perception of participants, and revised IPA is considered to judge outputs by identifying participant's importance based on the satisfaction of the project performance. Therefore, if IPAs are applied according to the characteristics of the circumstances, it is possible to analyze the perception difference between end-users and construction experts based on the context before and after the construction of the daycare center.

Current research explores the effect of language on the perception of facial emotion as suggested by the psychological construction theory of emotion by using a psychophysical method. In this study, we hypothesize that the perception of facial expression may be influenced if the observer is shown an affective word before he/she judges an expression. Moreover, we suggest that his/her understanding of a facial emotion will be in line with the conceptual context that the word denotes. During the two experiments conducted for this project, a control stimulus or words representing either angry or happy emotions were briefly presented to participants before they were shown a target face. These target faces were randomly selected from seven faces that were gradually morphed to show neutral to angry (in Experiment 1) and neutral to happy (in Experiment 2) expressions. The participants were asked to perform a two-alternative forced choice (2AFC) task to judge the emotion of the target face (i.e., decide whether it is angry or neutral, or happy or neutral). The results of Experiment 1 (when compared with the control condition) showed that words denoting anger decreased the point of subjective equality (PSE) for judging the emotion of the target as anger, whereas words denoting happiness increased the PSE. Experiment 2, in which participants had to judge expressions on a scale from happy to neutral, produced a contrasting pattern of results. The outcomes of this study support the claim of the psychological construction theory of emotion that the perception of facial emotion is an active construction process that may be influenced by information (such as affective words) that provide conceptual context.

This study is a part of our research project that considers 'Science as Wisdom (SaW)' as a new approach to science education. We presented a review of previous studies on wisdom from relevant areas as philosophy, psychology and education, and drew a few educational meanings. We also conducted a survey of science teachers' perception of wisdom to obtain implications for a follow-up study. The survey was conducted on pre-service science teachers, in-service science teachers, and teachers of other subjects. The results of this study are as follows: First, all three groups of participants perceive 'practical' domain of wisdom as most important while 'interpersonal' domain was perceived as least important. Second, all three groups of participants perceive that 'to catch what the most important problem is,' is the most important among 20 elements of wisdom. Third, when participants were asked about the 'wise people around them', the interpersonal domain followed as the second most frequent response after the 'practical' domain, which was in contrast to our first finding above. Fourth, about 80% of all participants answered that wisdom can be cultivated through school education. Finally, answers to the question asking the scientific concepts related to wisdom were categorized into four types as follows: (1) the wisdom required to understand and apply scientific knowledge, (2) the wisdom included in the meaning of scientific knowledge, (3) the wisdom needed to discover scientific knowledge, (4) the wisdom that can be developed through scientific activities.

Problem Based Learning (PBL) is one of methods which has been developed to promote student-centered learning and to pursue self-directed learning for life-long learning. The purpose of this study is exploring the possibility of Problem Based Learning (PBL) in college Earth science course. The participants of this study were fourteen students attending an Earth science class at Sookmyung Women's University in Seoul. PBL was implemented in the form of group project with utilizing Web-based course tool. We provided questionnaires and conducted interviews to figure out students' perception about PBL. The findings were as follows: Through a given experiences, (1) students participated more actively than LBL (Lecture Based Learning), (2) more students were engaged with self-directed learning, and (3) students made higher cognitive efforts. LBL seemed to be more efficient way to acquire factual knowledge. In the meanwhile, PBL did not seem to affect the improvement of communication skills. Students could not make use of Web-based course tool effectively in communicating with other team members. In this study, we found that college student participants preferred problems related to everyday life, environmental issues and interesting but unusual incidents. On the other hand, they felt difficult in open-ended problems, especially when they were asked to provide their own evaluation. On the basis of PBL experiment in this paper, we present one method of successful implementation of PBL and suggest topics which should be studied in the future.
