The improvement of safety and health education method in construction site was investigated through the survey for workers and delphi technique. The results of preliminary survey done for workers were analyzed using the multi variance analyses, and the questionnaires for delphi survey were composed based on the results of preliminary survey. Finally, the participatory safety and health education method was suggested. The result showed that most of workers were very interested in accident prevention and health. On the contrary, they did not actively participate in safety activities in sites including safety and health education. In order to improve workers' levels of safety consciousness and prevent the construction accident, the participatory safety and health education method that construction workers directly examine and give presentations about accident causes and measures was suggested and verified by tests. One-way instructor-led safety and health education used widely and participatory safety and health education with workers were carried out by dividing participants into two groups. After education, the examination is done for two groups. The test results found that the average score of safety consciousness of the worker group that received participatory safety education was higher than that of the work group that received instructor-led safety education. And the Delphi technique utilizing experts was analyzed that participatory safety education has a great effect on improvement of workers' level of safety consciousness.

Recently, conservation and utilization of cultural heritage has been regarded as importance. So, various research papers about maintenance of the remains have been presented in many conferences. But most of researches have focused on introduction about maintenance methods and explanation about maintenance concepts of remains. And even in case of a few papers treated post-evaluation about maintenance of the remains the criteria of the evaluation has tended to somewhat subjective. So, the purpose of this study is to show the objective post-evaluation indexes which was developed by Delphi AHP methods. This research was proceeded in two stages. First, we arranged the evaluation index in a hierarchy to be made through the analyses about references and researches about maintenance of remains. 304 evaluation articles were elicited through the process. And then, elicited evaluation articles were classified with 'conservation' and 'utilization'. Second step was to figure out importance and validity of hierarchical evaluation articles with twice questionnaire surveys. This research used interval scale to comprehend validity and AHP method to evaluate relative importance of each other articles.

Objectives: It is critical to assess community readiness (CR) when implementing childhood obesity prevention programs to ensure their eventual success and sustainability. Multiple tools have been developed based on various conceptions of readiness. One of the most widely used and flexible tools is based on the community readiness model (CRM). This study aimed to adapt the CRM and assess the validity of a community readiness tool (CRT) for childhood obesity prevention programs in Iran. Methods: A Delphi study that included 26 individuals with expertise in 8 different subject areas was conducted to adapt the CRM into a theoretical framework for developing a CRT. After linguistic validation was conducted for a 35-question CR interview guide, the modified interview guide was evaluated for its content and face validity. The quantitative and qualitative analyses were performed using Stata version 13 and MAXQDA 2010, respectively. Results: The Delphi panelists confirmed the necessity/appropriateness and adequacy of all 6 CRM dimensions. The Persian version of the interview guide was then modified based on the qualitative results of the Delphi study, and 2 more questions were added to the community climate dimension of the original CRT. All questions in the modified version had acceptable content and face validity. The final CR interview guide included 37 questions across 6 CRM dimensions. Conclusions: By adapting the CRM and confirming linguistic, content, and face validity, the present study devised a CRT for childhood obesity prevention programs that can be used in relevant studies in Iran.

In order to maximize profitability by optimizing the entire supply chain process, enterprises have made efforts to apply IT technologies such as POS, MES, and TMS. In addition, academic societies have also made efforts to verify the effects of IT technology introduction through various researches. However, until now, there is almost no research that analyzes the relationship between the IoT, a new IT technology, and the SCM. To study the effect of IoT technology on SCM, this study conducted professional Delphi surveys for three times. Through this method, this study analyzed changes that will be caused by the IoT technology, the priority area in IoT introduction, and the expected difficulty in IoT introduction on SCM. As a result of the Delphi surveys and analyses, it was expected that when IoT technology is introduced, the level of SCM's IT use and partnership will increase. However, the effect of the increased performance of the supply chain, which includes inventory management and quality control, will become weaker. The reason is that the development of operation and management skills, as well as the improvement of IT technology, are also important elements for the performance improvement of the supply chain. As for the priority area in IoT introduction, it was expected that the effect will be greater when IoT is introduced in customer service, transportation, and delivery areas. As difficulties in IoT technology introduction, such as the shortage of IoT platform development personnel, standardization, integration with the existing system, securing professional manpower, expenses, data management, and operation, were derived, it has thus become necessary for us to exert greater efforts in order to come up with solutions.

본 연구에서는 바리스타 교육에 대한 국내의 바리스타 전문가의 의견을 수렴하고 바리스타 교육기관에서 이루어지고 있는 교육프로그램과 비교분석함으로써 현 바리스타 교과과정의 문제점 및 개선방향을 모색하였다. 교과과정의 문제점과 개선점을 파악하기 위해서 현재 바리스타 교육을 하고 있는 15명의 전문가를 대상으로 델파이 기법을 이용하여 이들의 의견을 도출하였다. 전문가의견을 종합하면 바리스타의 교육기관의 교과과목을 구성하는데 있어 실무 중심의 커피교육이 중점적으로 이루어져야 하며, 실질적으로 취업에 필요한 카페운영기법 및 마케팅 등의 교육을 필요로 하는 것으로 나타났다. 또한 전문가들은 고객과의 접점에서 근무를 하는 특성상 서비스 과목을 강화하고, 매출의 많은 비중을 차지하는 제과제빵에 대한 교육도 필요한 것으로 제안하였다. 그러나 현재의 바리스타를 교육하고 있는 교육기관의 교과목을 살펴보면 이러한 교육은 매우 취약한 것으로 나타나 전문가들이 제안한 교과목들에 대한 보완이 필요한 것으로 보인다.

In two dimensional incompressible flaws, a preconditioning technique called Hierarchical Iterative Procedure(HIP) has been implemented on a SUPG finite element formulation. By using the SUPG formulation, one can escape from the LBB constraint and hence achieve an equal order formulation. In this paper, we increased the order of interpolation up to cubic. The conjugate gradient squared(CGS) method is used for the outer iteration, and the HIP for the preconditioning for the incompressible Navier-Stokes equation. The hierarchical elements has been used to achieve a higher order accuracy in fluid flaw analyses, but a proper efficient iterative procedure for higher order finite element formulation has not been available so far. The numerical results by the present HIP for the lid driven cavity flaw showed the present procedure to be stable, very efficient and useful in flaw analyses in conjunction with hierarchical elements.

An image analysis program with the function of measuring various quantitative characteristics in the transverse surface of wood was developed using Delphi 2.0. Data on pore characteristics (conditions for image processing, proportion of pores in relationship to other elements, tangential diameter, area, tangential and radial diameter, x and y coordinates of pore center, and geometric coefficients) were saved in text file format. In addition, the pore area histogram in the tangential and radial directions was saved as a BMP (bitmap) type file. Analyses indicated that quantitative characteristics such as the relative radial distribution of pores in a growth ring, pore tangential area histogram, and proportion of pore in lumen area appear to be useful in separating four diffuse-porous woods and four ring-porous woods on the species level.

As the impacts of climate change have been emerged all the way through society, the potential risks specifically on agricultural water and facilities are recently getting concerned. Evaluating vulnerability of agriculture to climate change on is a time-tested strategy. While a number of researches on the adaption and mitigation of climate change were performed in various aspects for sustainable agricultural production, the vulnerability of management system for agricultural water and infrastructure has not been investigated yet. This study is aimed to clarify the definition of vulnerability to climate change, find the major indicators able to presume the vulnerability, and finally determine the relative importance of the indicators based on the specialist questionnaire survey and its analyses. The lists of indicators for major parts of agricultural water management such as, water use, flood control, reservoir related issues, and pumping and drainage systems are initialized referring to the related precedent studies. The primary survey was conducted in the form of Delphi to complement the list and methods and the main survey was then conducted using AHP(Analytic Hierarchy Process) technique to quantitatively prioritize the indicators. The results derived in this study would be directly adopted in weighting importance of indicators to investigate the indicator-based vulnerability analysis to climate change in agricultural water and infrastructure management.
