  • Objectives: The definition of Sanhupung (Puerperal wind disorder) has been varied and there has been a prior study to establish the definition, but no clear conclusion has been reached on diagnostic criteria. Therefore, the aim of this study was to clearly redefine the definition of Sanhupung using the Delphi method. Methods: This study used the Delphi technique. A panel consisting of 13 experts of Korean medicine, particularly in Obstetrics & Gynecology, participated in the Delphi survey that included answering the 3rd round survey. The Delphi survey was conducted by evaluating and correcting the questionnaire using e-mail. Results: Through the Delphi survey, we have reached an agreement regarding the diagnostic criteria of Sanhupung. They are as follows: 1) Sanhupung can be diagnosed based on basic symptoms. If one or more symptoms are expressed in the basic symptom group, it can be diagnosed as Sanhupung. It is diagnosed in detail as a pain type or a sensory impairment type according to the category of basic symptoms. 2) Incidental symptoms are not essential for diagnosis, and are referred to for checking general weakness and autonomic nervous system conditions. 3) In order to meet the diagnostic criteria, the symptoms should occur within 6 months after childbirth or miscarriage, and the cause of the symptoms should not be classified as other diseases. Conclusions: The diagnostic criteria of Sanhupung were suggested based on the Delphi survey among experts in the field. Further research is necessary to improve the reliability and validity of the criteria.

  • Objectives This study aimed to develop consensus-based recommendations for establishing standard clinical practice guidelines for pediatric anorexia through the utilization of a Delphi study. Methods We analyzed existing randomized controlled trials for pediatric anorexia treatment using the Delphi method-a structured process for achieving consensus among a panel of experts. A questionnaire was distributed among a select panel of nine specialists in the field. Results The initial Delphi round led to consensus on 30 distinct recommendations; however, consensus was not reached for 19 other recommendations, prompting a second Delphi round. In the subsequent round, adjustments were made based on feedback from the initial round, and deliberations were held on recommendations that previously lacked consensus. Following these adjustments, consensus was achieved on all recommendations. Additionally, a third Delphi iteration was conducted to address three specific queries that required amendment due to a reevaluation of the evidence levels of certain recommendations. In total, three Delphi rounds were carried out to produce informed recommendations related to the diagnosis, treatment, and general management of anorexia. Conclusions This investigation successfully generated evidence-based recommendations for the diagnosis and treatment of pediatric anorexia. The recommendations encompassed various practices, including herbal medicine, acupuncture, moxibustion, cupping, and Chuna manual therapy, which can be integrated into clinical settings.

  • This paper employed typology and stratification as key elements to estimate quality evaluation of vinegar drink through Delphi and AHP(analytical hierarchical process) method to contribute the market expansion of the vinegar drink as a health drink. Through literature research and brainstorming with professionals, the first round of Delphi method was conducted with the open-ended questions including five upper concepts, i.e. 'ingredients', 'production method', 'product characteristics', 'functions' and 'packaging design'. Original study had 50 lower concepts as a result of the first round and added 'marketing' as an additional upper concept. The second and third round of Delphi method have been conducted with closed-ended questions based on the 50 lower concepts resulted from the first round. To seek concordant objectivity among the answers from the survey, the study used Kendall's W coefficient of concordance. 11 items were removed while 16 items were removed at the third round leaving 23 items through second round of Delphi method. For the final round, this study utilized the Pairwise Comparison Method to figure out the relative importance of the 23 items for the prioritization. Finally, current study formulated the final items which should be considered as an important factor in the quality evaluation of vinegar drink.

  • Usually, processing whole project or a part of frame work delays due to acceleration, changing orders, management, characters of project. overtime, worker crowding, early occupation in the field of construction. Through a whole project, these factors cause decreasing construction labor-productivity which is the most dependent in business of construction. These kind of decreasing of construction labor-productivity cause many negative effects, just as extension of time, increasing cost in project of construction. Regardless of characters of construction or decreasing labor-productivity, extension of time is a incident which needs acceleration, also it cause a high possibility of claim and dispute. The productivity has just a broad meaning in business of construction. That's why it's difficult to apply in the field of construction. Especially, factors increasing or decreasing labor-productivity is defined by analysis of working as qualitative and outlined evaluation. However, study of the each factor decreasing construction labor-productivity analysis has not researched, because of difficulty of systematic measurement and management. The existed studies about management of productivity are just focused on estimation of productivity, not on evaluation of productivity. It was true that I couldn't examine clearly about the analysis of how much important per each the factor which have influence on labor-productivity because of the characteristic as qualitative that the labor productivity have On this study, i tried to get the factors decreasing of labor- productivity with gathering opinions of panels of expert's studies about the factors decreasing of labor-productivity on project of construction through Delphi method and i evaluated the result factors as quantitatively and subjectively about importance of factors decreasing construction labor-productivity Analysis, using AHP Method by Saaty. Also, using Delphi and AHP method, 1 suggest substantiated method qualitative factors are measured by quantitative criteria.

  • In the knowledge and information age, to discover and protect Intellectual Properties would be very important for their economic value as a major growth engine. This study evaluated the reliability of a Delphi survey conducted by experts to assess the value of agricultural resources knowledge obtained from literature reviews and field interviews. Delphi method is collecting the opinions of experts for several rounds repeatedly, in the next round the experts have chance to modify their opinion. Scores between two rounds are highly correlated and standard deviations are declined for second round to imply that some correction of their evaluations are made. To check reliability of Delphi survey of two rounds Cronbach's reliability coefficient and Generalizability coefficient are derived. The Cronbach alpha's supported the reliability of the method, but the Generalizability analysis revealed some unexpected results while checking the variance components of sources of measurement errors. Despite the increased reliability coefficients, the deviations between the raters are increased which means that additional rounds are required to get consensus, the goal of Delphi research.

  • This research is the first research on developing the speed limit select model and also it is the result of the research on the importance of each element and consideration factors when selecting the speed limit. For the consideration factor discrimination and calculation of the importance, the delphi method and AHP method was used. The delphi survey was processed through third round survey, 5 high consideration factor(Level 1) and 23 low consideration factor(Level 2) was discriminated. During the process of the third delphi survey, when the CVR cost was in the range between 0.4~1.0 it was treated as the consideration factor when selecting the speed limit and less than 0.4 cost was eliminated. In the process of the second delphi survey, 33 consideration factors were discriminated but was reordered into 23 categories through the third survey. Based on the 23 categories earned through the third delphi analysis, the AHP survey was processed. The result of the AHP survey was that out of the importance of the 5 high consideration factor(Level 1), the traffic condition was evaluated as the number one factor and the vessel condition, waterway condition, environment condition, supporting condition and etc. conditions were evaluated following the traffic condition. Out of the 23 low consideration factor(Level 2) consideration, the visibility was evaluated to be the first important and the performance of the vessel steering, objective factors within the harbor, amount of traffic and density, distance between the passing vessel, speed of the steering capacity and tidal current were the following evaluated factors.

  • 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.
