To achieve economic stability, distribution Company as an economic institution should be managed by various processes. In this way, knowledge of different processes is the first step. Furthermore, expectations, outputs, requirement data, and sub-processes should be extracted and determined. Accordingly, to assign the performance responsibility of each process, the decision-making points must be introduced and, the deviation or change in set-points should be investigated into processes. Also, the performance of processes could be monitored by introducing of the sub-indictors. In this study, a practical method is presented for monitoring of reliability and power loss indices from viewpoint components' supply chain into the distribution network. At first, the visibility model of the supply chain is illustrated by focus group and the sub-indicators are extracted for each process of this chain. Then, validation and verification of the sub-indicators are accomplished by the Delphi method and, an information dashboard is presented by confirmed the sub-indicators and statistics methods. Finally, the proposed method is investigated by real data in a typical network and the results are analyzed.

This study is to consider varying factors of internal/external informational and operational environments in libraries, and develop a new evaluation indicators for university libraries in digital environments. In order to do this research, the previous works have been investigated, and the Delphi study and our own analysis have been performed. The main research results are as follows. First, the results through the Delphi method that was to adopted to verify evaluation items and indicators determined by the literature review show that the repressed values for each evaluation category is greater than 3.00. overall average is 4.02. and standard deviation is ranged from 0.40 to 0.62 for each category. This means that the evaluation indicators are valid. Second, the factor analysis was performed to verify the construct validity of evaluation indicators. As a result. the cumulative variance of evaluation indicators consisting of 11 dimensions per factor is 72.733%. In turn, this result shows that the validity of these indicators is very reliable. Third, t-test and one way ANOVA are performed within significance probability 0.05 in order to verify differences in each librarians point of views for the degree of importance in evaluation indicators. The results show that these evaluation indicators are verified to be appropriate since there is no significant difference. Based on the Delphi study and our own analysis. we developed a new evaluation indicators that consists of 7 evaluation categories, 35 evaluation items, and 92 evaluation indicators.

In this study, I worked on necessary contents for Information Literacy of Korean universities by Delphi Method. The survey resulted in 100 necessary contents in five categories and each category presents average points and ranks of importance. Contents of high rank in each category should be valued highly when educational programs are to be designed. One remarkable difference in comparison with ACRL standards is that there are a lot of contents involved with basic understanding about Scientific Information System and Information Technology and knowledge application in this study, and another is that there is a lack of contents which require analytic judgements. The significance of this study lies in presenting directions and discussion points in designing of Information Literacy of Korean universities.

It is used to lead to serious structural vulnerability of the system security of security-critical system when we have quickly developed software system according to urgent release schedule without appropriate security planning, management, and assurance processes. The Data Set and Provider of DataSnap, which is a middleware of Delphi XE2 of the Embarcadero Technologies Co., certainly help to develop an easy and fast-paced procedure, but it is difficult to apply security program and vulnerable to control software system security when the connection structure Database-DataSnap server-SQL Connection-SQL Data set-Provider is applied. This is due to that all kinds of information of Provider are exposed on the moment when DataSnap Server Port is sure to malicious attackers. This exposure becomes a window capable of running SQL Command. Thus, it should not be used Data Set and Provider in the DataSnap Server in consideration of all aspects of security management. In this paper, we study on the verification of the security vulnerabilities for Client and Server DataSnap in Dlephi XE2, and we propose a secure coding method to improve security vulnerability in the DataSnap server system.

The main purpose of this study was to derive managerial priority for pollutants in drinking water using the Delphi technique and analytic hierarchy process (AHP) method. We collected fundamental existing items based on a literature review for water pollutants, and deduced a total of 36 sub-items from nine core sectors, as follows: organic matter; inorganic substances; pathogenic organisms; chemicals; heavy metals; radioactive substances; sediment deposits; heat; and oil, and then conducted the first round of an expert study to ensure that objective indicators properly evaluate major issues for management of for drinking water quality. In the following round, the necessity and importance assessments of adjusted items were implemented using a content validity ratio index. Finally, items modified by Delphi surveys were applied to AHP. We computed weighted values by pair-wise comparison of sub-items and each of five sectors modified by the second round. According to the results of AHP, the managerial priority for pollutants in drinking water was as follows; while heavy metal placed first in importance, pathogenic organisms came second, followed by inorganic substances, organic matter and chemical substances from the sector perspective.

We studied an activation plan for utilizing eco-friendly agricultural products from agricultural producers' perspective through delphi techniques. Certification types of eco-friendly agricultural products held by producers were low-pesticide 26.1%, no-pesticide 39.1% and organic 52.2%. The major problems in handling the eco-friendly agricultural products were as follows: 'consumer distrust', 'lack of reliable and continuous shipping quantity' and 'lack of storage facilities, such as cold storage'. The major benefits of direct transactions between producers of eco-friendly agricultural products and processed food manufacturers including HMR processing companies were 'obtaining fresh food ingredients for processing' and 'confidence-building and income stabilization'. Regarding requirements for cooperation of eco-friendly agricultural producers and processed food manufacturers including HMR processing companies, the most common answers was 'multi-year contract based on trust'. When asked about governmental support for efficient cooperation between eco-friendly agricultural producers and processed food manufacturers including HMR processing companies, the most common answer was 'supporting plan for small producers' and 'arrangement for appropriate potential consumers'.

Purpose: The purpose of this study was to develop a first aid coaching program (FACP) and to investigate its effects on the first aid knowledge, confidence, and performance of childcare teachers. Methods: A Delphi survey that included 16 experts was used to develop the FACP. A total of 60 participants were included to test the effectiveness of the program. The FACP developed using the survey results focused on improving first aid knowledge, confidence, and performance using a coaching-based method. First aid and cardiopulmonary resuscitation (CPR) performance was assessed using 39 items from the program content. Results: Using a 3-round Delphi survey, 6 areas and 42 detailed topics for group and individual coaching programs were developed. The knowledge scores were significantly higher in the experimental group than in the control group (t=4.24, p=.001). The confidence scores were significantly higher in the experimental group than in the control group (F=3.89, p<.001). The performance scores were significantly higher in the experimental group than in the control group (t=12.40, p<.001). Conclusion: Continuous application of the FACP among child care teachers is expected to minimize the harm caused by minor accidents at child care facilities. This program should be formally implemented on a consistent basis.
