The aim of this study is to develop and construct the elements of a new evaluation tool to assess the effectiveness of a horticultural therapy. Delphi method was applied to classify the realms of evaluation and specify their components and constituting items. Delphi process was performed through three rounds and 24 professionals attended all the rounds as panel members. Some of the items were revised or removed according to the results of such tests as content validity ratio, agreement rate, convergency and stability of each item. On the contrary, a few new items were added by accepting the opinions of the professional panels. Previous to the Delphi, the realms of evaluation were classified into physical, cognitional, psycho-emotional and social ones on the basis of literature review, professionals' consultation and in-depth interview with practitioners. At the first round, 112 items constituting four realms were reviewed. The numbers of items to be reviewed were reduced to 107 at the second round and to 102 at the third round. As a result, 98 items in 4 realms were decided as proper evaluation points of horticultural therapy. The compositions of the four respective realms are as follows: 5 components and 27 items in physical realm; 4 components and 25 items in cognitional realm; 2 components and 24 items in psycho-emotional realm; and 4 components and 22 items in social realm. These realms, components and specific items derived from this study constitute indices to evaluate the effectiveness of horticultural therapy. In addition, they might be utilized as good guidelines for planning horticultural therapy programs.

A strategic technology selection for GHG reduction is crucial to secure mitigation means. Especially, a technology selection for a public sector is encouraged to consider integrated perspectives due to various stakeholders under public goals. However, previous studies have mainly focused on technological and economic factors, moreover, consistent criteria have not been applied. This study develops indicators for the GHG reduction technology selection from the public perspective based on delphi method with 22 experts. The result provides valid indicators of technology selection for GHG reduction considering an aspect of technology, economics, environment, policy, society. Specifically, 16 indicators from 5 categories on commercialized technology, and 18 indicators from 5 categories on new technology. We expect that those indicators are useful for a decision-making tool of technology selection. Moreover, provide the basis for the study of judgement criteria to evaluate GHG reduction technology.

In this study, the Delphi method and AHP (analytic hierarchy process) were used to evaluate tunnel collapse risk from a comprehensive and multifaceted perspective. Influence factors were established through literature reviews, previous studies, and brainstorming sessions with expert groups, resulting in the construction of five main classification systems. A panel of 21 experts was formed, and three rounds of Delphi surveys were conducted to prevent errors and biases in the expert judgment process, thereby enhancing reliability. Ultimately, 14 influence factors were identified through CVR (content validity ratio) and COV (coefficient of variation) analyses of the experts' responses. Subsequently, the AHP method was applied to assess the relative importance of each influence factor and calculate the final composite weights. The timing of support and reinforcement had the highest priority, followed by groundwater inflow, joint conditions, support pattern levels, and auxiliary methods. These findings help identify the key factors affecting tunnel collapse risk and provide a foundation for developing strategies to improve tunnel safety.

According to the purpose of the study, the study was conducted as follows. First, from October 4 to November 15, 2022, a Delphi survey was conducted on 21 experts with experience of consulting, research, class development, and operation related to the K-MOOC project. Second, in order to realize the tasks in the teaching method field derived from the Delphi survey, matching with the teaching method class model elements to result of Delphi survey was applied was carried out. Finally, based on the results of expert Delphi and the elements of the class model applicable to the metaverse platform, a teaching method was developed. Through the process of the study, a total of 16 detailed items were derived for the teaching method-related tasks for the activation of K-MOOC: support strategic tasks, teaching method competency, aspect of class design, evaluation and sharing of learning outcomes. By applying the metaverse, the teaching model elements for K-MOOC revitalization were derived from four categories: self-directed repetition, individualized problem solving, practice opportunity expansion, and immediate feedback, and matched with the first 16 detailed items. A four-step teaching model was completed: course attendance (step 1), mission analysis by individual level (step 2), sharing of mission solutions (step 3), and mission evaluation and feedback (step 4). Through the results of this study, the possibility of using the metaverse as a teaching practice platform was confirmed even in terms of the introduction and development of specialized techniques.

The purpose of this study was to investigate the characteristics of convergence education through the Delphi survey targeting 19 teaching professionals. The Delphi survey was completed three times, drawing key factors and expected outcomes which explain the characteristics of convergence education. The key factors of convergence education were classified as 'educational design', 'teachers' expertise' and 'educational environment'. Educational design focused on the qualitative characteristics of leaner's experience. Teachers' expertise was teacher's active and supportive roles in relationship with fellow teachers and learners. Educational environment was the psychological factors with which various subjects can realize convergence education. The expected outcomes were classified as 'learner's cognitive characteristics', 'leaner's affective characteristics', and 'teacher and educational system'. The expected outcomes of convergence education leads to psychological changes for learners to increase the advanced learning experiences and to pursue values of education itself. Compared to similar concepts, convergence education has some unique characteristics in which many of regular learners in educational settings and various topics are targeted. It also focuses on psychological factors of various subjects and qualitative natures of leaners' learning experience for the advanced learning. Especially, these results have significance in understanding the nature of convergence education, focusing on educational practices through teachers'perspectives.

Since CM for Fee has been introduced in domestic market of construction industry, Construction Management(CM) has been familiar with one of the established delivery systems in Korea. However, CM(CM for Fee) construction market has been stagnant consistently due to recent economic recessions. The fundamental causes of the current depression of CM construction market are highly related to the social/environmental factors(such as owner's negative perception about CM services, exclusive formation of the CM markets, unfeasible fee and limitations on technology developments in CM services) and the shortage of institutions associated with CM. Accordingly, fundamental improvements on the CM environment are required. This study suggests the feasible methods for improvement on CM system based on fundamental analysis of problems related to the environmental factors by conducting a delphi technique with professional personnels on various positions in CM markets.
