This study aims to analyze both the current utilization of e-learning in the scuba diving education sector and the possible improvements by using Delphi analysis. The study administered three rounds of Delphi surveys with 25 specialists, including business executives and educational leaders from scuba diving centers and resorts affiliated with organizations that conduct scuba diving education through e-learning. The comparative analysis of the state of e-learning utilization and factors for improvement revealed significant insights. In terms of expected benefits, the analysis highlighted an increase in user convenience, temporal flexibility in learning activities, and easy access to products. However, it identified major issues such as the simplistic mandatory exams, inadequate professional depth in the feedback provided, and a lack of bidirectional communication between learners and instructors. Recommendations for improvements included enhancing communication through various online communities, conducting mandatory exams offline, and developing a variety of content. Conducting regular program quality evaluations, integrating with various diving communities, and assigning dedicated tutors were deemed crucial factors for future development.

A systemic review on the factors affecting food catering hygiene was conducted to provide information for risk management of food catering in Korea. In total 47 keywords relating to food catering and food hygiene were searched for published journals in the DBpia for the last decade (2005-2014). As a result, 1,178 published papers were searched and 142 articles were collected by the expert review. To find the major factors affecting food catering and microbial safety, an analysis based on organization and stakeholder were conducted. School catering (64 papers) was a major target rather than industry (5 pagers) or hospitals (3 papers) in the selected articles. The factors affecting school catering were "system/facility/equipment (15 papers)", "hygiene education (12 papers)", "production/delivery company (6 papers)", food materials (4 papers)" and "any combination of the above factors (9 papers)". The major problems are follow. 1) The problems of "system/facility/equipment" were improper space division/separation, lack of mass cooking utensil, lack of hygiene control equipment, difficulty in temperature and humidity control, and lack of cooperation in the HACCP team (dietitian's position), poor hygienic classroom in the case of class dining (students'), hard workload/intensity of labor, poor condition of cook's safety (cook's) and lack of parents' monitoring activity (parents'). 2) The problem of "hygiene education' were related to formal and perfunctory hygiene education, lack of HACCP education, lack of compliance of hygiene practice (cook's), lack of personal hygiene education and little effect of education (students'). 3) The problems of "production/delivery company" were related to hygiene of delivery truck and temperature control, hygiene of employee in the supplying company and control of non-accredited HACCP company. 4) The area of "food materials" cited were distrust of safety regarding to raw materials, fresh cut produces, and pre-treated food materials. 5) In addition, job stability/the salary can affect the occupational satisfaction and job commitment. And job stress can affect the performance and the hygiene practice. It is necessary for the government to allocate budget for facility and equipment, conduct field survey, improve hygiene training program and inspection, prepare certification system, improve working condition of employees, and introducing hygiene and layout consulting by experts. The results from this study can be used to prepare education programs and develop technology for improving food catering hygiene and providing information.

This study was performed to develop a children's dietary life safety index required by the Special Act on Safety Management of Children's Dietary Life enacted in 2009. An analytical hierarchy process was used to obtain initial weights of dietary life safety evaluation indicators. The Delphi method was applied to develop the weights along with 98 food and nutrition professionals. Three representative policy indicators, nine strategy indicators, 11 main evaluation indicators, and 20 detailed evaluation indicators were selected for the children's dietary life safety assessment. Three policy indicators and nine strategy indicators were the following: children's food safety indicator (support level of children' safety, safety management level of children's favorite foods, and safety management level of institutional food service), children's nutrition safety indicator (management level of missing meals and obesity, nutrition management level of children's favorite foods, and nutrition management level of institutional food service), and children's perception and practice level indicator ("Dietary Life Law" perception level, perception, and practice level for dietary life safety management, perception, and practice level for nutrition management). Weights of 40%, 40%, and 20% were given for the three representative policy indicators. The relative importance of nine strategic indicators, which were determined by the Delphi method is as follows: For children’s food safety, support level of children's safety, safety management level of children's favorite foods, and safety management level of institutional food service were given weights of 12%, 9%, and 19%, respectively. For children's nutrition safety, the missing meals and obesity management level, nutrition management level of children's favorite foods, and the nutrition management level of institutional food service were given weights of 13%, 11%, and 16%, respectively. The "Dietary Life Law" perception level, perception and practice level of dietary life safety management, and perception and practice level of nutrition management were given weights of 4%, 7%, and 9%, respectively.

Roundabouts are recently paid a lot of attention, but in the process of implementation, there are insufficient logical grounds for clear criteria and priority of introduction. As a result, in determining priority of introduction of roundabouts, a local government often depends on a policy maker's subjective judgement. Therefore, this study was conducted to suggest methodology for priority decision of introduction of roundabouts. Assessment elements of six main elements including accident type at intersections and each one has three subelements. Survey was carried out targeting fifty-three public officials in charge and experts in order to analyze the significance of each assessment element. The theoretical background of analysis is based on AHP developed by Saaty, which is one of multiple criteria decision making methods. 'Expert Choice 2000' was used as a software program. Five intersections representing different situations were selected as examples of analysis. It was also paired with sensibility analysis to grasp how priority might be changed by different weight. Through this result, it can be inferred that priority might change by manipulating field situation from other areas.

Local food industry has been spreading all over the world. Korea is also actively applying and developing local food industry. However, relatively high distribution cost in Korean agricultural market is hindering its further growth. Distribution cost has close relation with shipping distance. Raised distribution cost brings major impacts not only on quality and price of products but also on greenhouse gas(carbon dioxide) emissions. Therefore, it is necessary to find a solution for inefficient distribution system of the local food industry to reduce overall cost and greenhouse gas. In this study, we present a location selection model for local food regional center using Analytic Hierarchy Process. The location of local food regional hub center is decided based on expert opinions on five factors: accessibility, quality, population, size of area, and shipping distance. The relative importance of the five factors has been concluded as follows: quality (0.430) ${\gg}$ population (0.262) ${\gg}$ travel distance (0.201) ${\gg}$ accessibility (0.075) ${\gg}$ and area (0.033). We apply and analyze the environmental management system model for Local food industry to develop the regional hub center site selection criteria and to analyze the effects of greenhouse gas emissions in the local food industry. This study, by applying and analyzing the environmental management system of the local food industry, is believed to be a valuable asset for managing greenhouse gas emission in the local food industry. Also, the data will be used for the autonomous local food industry's direct sales stall management. Eventually, this study will contribute so greatly to the local food industry's competitiveness that even large distribution companies will give way for the local food industry.

Environmental disputes not only possess the special characteristics of collectivity and plural value relativity but it also possesses the unique features of difficulty to prove cause and effect as well as the structural maldistribution of evidence and information. Therefore, the positive resolution of an environmental dispute can be brought about more easily with the Alternative Dispute Resolution (ADR) which can take the form of talks, compromises, as well as arbitration or mediation rather than through a trial process. Such being the case, this paper first looks into the problems and effectiveness of the arbitration system of environmental lawsuits and then takes an even closer look at Korea's environmental dispute arbitration system and finally offer some reform methods. In Korea, the environmental dispute arbitration system was implemented in 1991 and has been executed since then. Although this system does have positive features such as the high rate of coming to an agreement between the involved parties but unfortunately, most of the cases rely on decisions based on right and wrong which cannot but be far away from the intentions of the ADR system. It is heavily centered around claims regarding psychological compensation regarding noise and vibrations and the ratio of the actual amount of compensation is comparatively lower than the requested amount. In addition, with the limits in organization and manpower, it leads to a lack of professionalism as well as the problem of low usage with the low awareness rate. As reform measures against the aforementioned problems, this paper suggests the following. First, in order to activate the arbitration process more fully, it proposes aggressive usage of compulsory arbitration as well as submission to arbitration, while at the same time raising ADR professionals to fill in the missing gaps. Secondly, in order to overcome the problem of concentration of related cases, making representative lawsuits of environmental organizations would be a good idea. It also states that in order to make the compensation amount more realistic, it should go out of the across-the-board decision making process and reach a decision about the compensation amount that takes the individual situation's dispute into consideration. In order to boost the professionalism of the environmental dispute arbitration, it is necessary to reform the organization and manpower such as expanding the number of members of full standing, and increasing the professionalism of the examiners. Also, to increase the usage rate of the ADR system, the paper suggests stationing a civilian consultant regarding environment, or activating the compulsory arbitration which is the premise for public participation on the part of the residents.

The purpose of this study was to investigate the application of GLOBE program in Korea and its perception displayed by the Science High school Teachers. The interview using a questionnaire with 12 science high school teachers in Korea was conducted. It was attempted to find a problem occurring during the practical application for getting a basic data for the development of Korean GLOBE program. The results of this study are as follows: (1) The level of GLOBE program was for upper grade levelsin elementary school and middle school. The program may not be suitable for the Science High School students in Korea. (2) To successfully apply the GLOBE program in Korea, study levels and research subjects in the program must be further developed in terms of quality and areas. Suggestions for the possibility of adopting and operating the program in Korea are made as follows: (1) To effectively manage the GLOBE school sites, there has to be a headquarter system in place and operation under, say, the Korean Earth Science Society. (2) To ensure the program's identity and goals, it is to set up a center for the Korea GLOBE program with a financial support system established.

We investigated the frames represented in the news media coverage in Korean daily newspapers during dismissal procedure of the director-general of the public service broadcaster, KBS. We analyzed 470 newspaper stories in the period surrounding the dismissal. The use of news frames in newspapers depended on the disposition of outlets, conservative or progressive. Conservative newspapers, ChoSun and DongA, described the dismissal of the director -general with a generally favorable or supportive view, but progressive outlets, Hankyoreh and KyeongHyang, reported more and non-favorable for the issue. Our results showed that conservative newspapers more often used episodic and cause for dismissal frame in the presentation of news, whereas progressive more often used thematic and media independence frames. Main frames commonly used in the news are the cause for dismissal, conflict, media independence, and regime maintenance, respectively, which are formed by 9 minor news frames. Conservative newspapers concentered on the cause attribution; management responsibility, conflicts, and dismissal procedures, but progressive focused on media independence and dismissal procedures. All newspapers selectively quoted groups, institutions and actors to enhance their messages and frames. Finally, there was significant difference between stories in each newspapers and the court's ruling for the dismissal.
