Background and objective: This study was conducted to identify the components of kindergartener horticultural education by deriving objective components of horticultural education using the Delphi survey method, and then to provide basic data that can be used when creating horticultural programs in the regular curriculum. Methods: A total of 32 experts including professors of early childhood education, kindergarten directors, horticultural therapy professors, and horticultural therapists were selected as the Delphi panel. Of the 32 selected, only 29 answered all three rounds of the surveys. For the first round of the survey, an open-ended questionnaire, was used, and in the second and third rounds closed-ended questionnaires were used. Results: Results indicated that under the category of the goals of horticultural education, there were 7 items related to the current problems of horticultural education, 16 items related to the need for horticultural education in the smart age, 18 items related to the direction of horticultural education, and 5 items related to the areas most suitable for horticulture education for young children in the Nuri Curriculum. Results in the category of the implementation of horticultural education indicated that 2 items related to horticultural education hours, 3 items related to the venue for horticultural education, 2 items related to the activity types applicable to the Nuri Curriculum, and 4 items related to the objects of horticultural activities were derived. As the current problems of horticultural education, the following items were identified: event-oriented activity (M = 4.24) and lack of kindergarten teachers' opportunities for systematic gardening education (M = 4.21). The results related to the necessity of horticultural education indicated the following items: education on respect for life through caring (M = 4.59), emotional intelligence and stability (M = 4.55), directly experience of the growth process of plants (M = 4.55), and development of the five senses (M = 4.55). Finally, within the direction of horticultural education: nurturing the desire to live with nature (M = 4.50), and learning about life (M = 4.44) was identified, which had higher averages. Within the areas of the Nuri Curriculum, which is most consistent with horticultural education, nature exploration (M = 4.69) and the integration of all areas (M = 4.59) were derived as priorities. Also, regarding the implementation of horticultural education, the following items were derived as the priority from the expert group: 30-40 minutes (M = 4.14) and 40-50 minutes (M = 4.14) for class periods, outdoor garden in a kindergarten(M = 4.66) for the venue of gardening education, outside play (M = 4.59) for the activity type, and vegetable crops (M = 4.55) for the objects of gardening activities. Conclusion: It is significant that the goal and implementation of kindergartner horticultural education were objectively derived through collecting opinions of expert panels. Based on the results of this study, a horticultural education program for kindergarten teachers should be implemented.

Background: The coronavirus disease 2019 pandemic has been challenging the healthcare service, i.e., the vitalization of the point of care accompanying self-testing in vitro diagnostic medical devices (IVDs). This study aims to suggest priority criteria to classify self-testing IVDs using the analytic hierarchy process technique. Methods: Two dimensions of the characteristics embedded in the IVDs and the diseases to be diagnosed with self-testing IVDs were parallelly considered and independently investigated. In addition, three expert panels consisting of laboratory medical doctors (n=11), clinicians (n=10), and citizens (n=11) who have an interest in the selection of self-testing IVDs were asked to answer to questionnaires. Priorities were derived and compared among each expert panel. Results: First of all, ease of specimen collection (0.241), urgency of the situation (0.224), and simplicity of device operation (0.214) were found to be the most important criteria in light of the functional characteristics of self-testing IVDs. Medical doctors valued the ease of specimen collection, but the citizen's panel valued self-management of the disease more. Second, considering the characteristics of the diseases, the priority criteria were shown in the order of prevalence of diseases (0.421), fatality of disease (0.378), and disease with stigma (0.201). Third, medical doctors responded that self-testing IVDs were more than twice as suitable for non-communicable diseases as compared to communicable diseases (0.688 vs. 0.312), but the citizen's group responded that self-testing IVDs were slightly more suitable for infectious diseases (0.511 vs. 0.489). Conclusion: Our findings suggested that self-testing IVDs could be primarily classified as the items for diagnosis of non-communicable diseases for the purpose of self-management with easy specimen collection and simple operation of devices, taking into account the urgency of the situation as well as prevalence and fatality of the disease.

This study was performed to develope a scale of gender role identity in Korean adults based on the Bem's theory of androgyny. Although there were several tools in Korea, they were revealed having some problems of cultural differences, translation biases, and methodological problems. Methods: A list of 78 items were developed using the existing tools and descriptions from 5 married couples. The items were the typical personality characteristics which were manifested by gender, male or female. And the list contained several items which were the socially desirable personality characteristics. which would be simply used as contextual items. Validity of the 78 items were screened by 18 expert panels with 4 point Likert scale, and 57 items were judged as highly valid from 70% of the experts, which were selected as preliminary items for the tool. Using the preliminary tool which was developed as a 4 point Likert scale, data were collected from 1,127 subjects for item analysis and factor analysis. 53 items were remained, because 4 items whose item-total correlation were lower than 0.2 were excluded by the result of item analysis. Factor analysis was done with the 53 items, and 49 items whose factor loadings were same and higher than 0.4 were remained. 3 factors were identified with eigen value 2.0, and these factors were named as masculinity, femininity, and social desirability. Results and Conclusion: KGRII(Korean Gender Role Identity Inventory) which contained 45 items was developed, with 15 items for 3 factors. The reliability of the tool was very high. Cronbach alpha of the tool was 0.929, and alpha of the subscales were ranged from 0.841 to 0.922.

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 this study, we present the modern hybrid system based power generation for electric vehicle applications. We describe the hybrid structure of modified current source based DC - DC converters used to extract the maximum power from Photovoltaic (PV) and Fuel Cell system. Due to reduced dc-link capacitor requirement and higher reliability, the current source inverters (CSI) better compared to the voltage source based inverter. The novel control strategy includes Distributed Maximum Power Point Tracking (DMPPT) for photovoltaic (PV) and fuel cell power generation system. The proposed DC - DC converters have been analyzed in both buck and boost mode of operation under duty cycle 0.5>d, 0.5<d<1 and 0.5<d for capable electric vehicle applications. The proposed topology benefits include one common DC-AC inverter that interposes the generated power to supply the charge for the sharing of load in a system of hybrid supply with photovoltaic panels and fuel cell PEM. An improved control of Direct Torque and Flux Control (DTFC) based induction motor fed by current source converters for electric vehicle.In order to achieve better performance in terms of speed, power and miles per gallon for the expert, to accepting high regenerative braking current as well as persistent high dynamics driving performance is required. A simulation model for the hybrid power generation system based electric vehicle has been developed by using MATLAB/Simulink. The Direct Torque and Flux Control (DTFC) is planned using Xilinx ISE software tool in addition to a Modelsim 6.3 software tool that is used for simulation purposes. The FPGA based pulse generation is used to control the induction motor for electric vehicle applications. FPGA has been implemented, in order to verify the minimal error between the simulation results of MATLAB/Simulink and experimental results.

As respiratory tract infections (RTI) account for about 60% of all antibiotic prescriptions in outpatient care setting, there are significant concerns about emerging resistance that are largely due to the excessive or inappropriate use of antibacterial agents for viral respiratory infections. This study was aimed to develop retrospective drug utilization review (DUR) program of antibiotics for RTIs using Delphi methods. Retrospective DUR criteria of antibiotics for RTIs were identified based on clinical practice guidelines and opinion of experts. Expert panel members were clinical doctors and pharmacists and Delphi method was applied by survey on 16 members of panels. The claim data from Korean Health Insurance Review & Assessment (HIRA) were used to examine trends in outpatient antibiotic prescription between Janunary to December of 2008. As results, Quality index for RTI was assessed for the claim type, antibiotics use of quantity, duration, number and cost. Antibiotic prescription rate for RTIs, Defined Daily Dose (DDD), and duration of antibiotics use were more recognized as significant quality index by experts' opinion. Use of first line agents suggested by guidelines was low and duration of antibiotics use was shorter compared to the recommendations. Antibiotics were over prescribed for RITs. However, dose and duration of antibiotics were under-used.
