The Korea Maritime Safety Tribunal is an institution that investigates marine accidents in accordance with the maritime safety adjudication procedure when marine accidents occur. It requires its investigators to be capable in specializing in marine accidents, including possessing the following: a level 2 or higher maritime license, experience on boarding, and specialized knowledge on ships. It also requires separate training for technical competency related to maritime accident investigations. However, the current education for marine accident investigators mainly consists of administrative tasks, which is not suitable to improving the investigator's technological competency, making its development urgent. This study aims to design training contents for marine accident investigators to strengthen their technical competence. To this end, we analyzed the contents of current investigator training, and reviewed the relevant laws and regulations, and training contents of investigators in advanced maritime countries and similar transportation institutions in Korea. According to the results, the training contents were designed to focus on strengthening technical competency, and proposed as a five-day course for basic and professional training. Based on the designed training contents, if in-depth research is conducted by sufficiently reflecting the working conditions of marine accident investigators in Korea, it will greatly help in improving the investigators' skills.

A webzine issued by a public institution not only plays a role in communication between members of the institution and its users, but is itself a meaningful record. In addition, as one of the management techniques of the archives, there is a growing awareness that active marketing is needed to promote the service and allow potential users to visit the archives. Therefore, efforts should be made to increase user satisfaction by identifying user needs, composing content reflecting them, and selecting user-centered interfaces appropriately. The purpose of this study is to design 'On-Gi', a newsletter of the Presidential Archives, as a user-participating smart platform in a smart device environment. As a research method, we first looked at the current status of webzine publication by relevant domestic institutions. Next, we compared and analyzed the issue of 'On-Gi' provided by the Presidential Archives and major contents. Based on this, a design model of the webzine for the marketing of the Presidential Archives was proposed. This can be used as a key marketing strategy for the Presidential Archives in the new user environment of technological innovation of smart devices.

This study is based on the assertion that science museums should consider visitors' views and expectations as they are not satisfied in many cases. In this study, we investigated 31 scientifically gifted students and 177 science high school students about their image of science museums. Using the questionnaire, it was found that only 51% of students visited science museums; however, the average number of visits was 4.2. This means that students tended to re-visit after the first visit of the science museum. Students had a 'good' image of science museums when they incurred hands-on experiences and observed new, interesting, curious and funny exhibits. And students had a 'bad' image of science museums due to the following aspects: lack of new and interesting exhibits, information and guide, diverse contents, and hands-on experience; deficiencies in environment; and inadequacy of the management, operation and composition of exhibits. Therefore, they hoped that science museums will provide more hands-on experiences and experiments, new and interesting exhibits, systematic management and composition of exhibits, information and guides, and a good environment. So science museums need to pay special attention to aspects like management, information guides and environment for the first-time visitors. Based on the above results, we suggested "Directions for a good science museum based on students' views". While asking students what topics they wanted to know and learn in a science museum, each student was given the choice of four topics; eventually, 2.9 answers overlapped for each topic. When classifying students' topics into four main themes for the Gwangju National Science Museum, the order from the most popular theme to the least one was 'science in everyday life', 'ocean/space/future science', 'light and science', and 'culture, art and science'. Among the topics mentioned by students, only 37% are exhibited in Seoul, Gwacheon, Daejeon, or Gwangju science museums. We hope that the results and research methods will be used for evaluation, re-construction, and reinvigorated presentation of science museums.

Daily last time of irrigation in perlite bag culture was investigated to get high water use efficiency (WUE) and fertilizer use efficiency (FUE) and also sustain high productivity for tomato. The water content in the substrate was higher as the last time of irrigation was later from 4 to 1hour before sunset. The growth were not significantly different in all treatments. The marketable yield was the highest in treatments of 1 or 2hours before sunset and the lowest in treatment of 4hours. In the result to investigate for 128days WUE and FUE were the lowest in treatment of 1hour before sunset but the highest in treatment of 3hours before sunset. In the conclusion, it looks best to end irrigation 2~3hours before sunset in the aspects of plant growth, yield, WUE, and FUE.

The study was performed to examine the elimination capacity of impurity on the fiberglass wicks to exert a suction of Passive capillary samplers (PCAPS) on soil water. This impurity affects the capillary properties of the wick and the chemical properties of the samples collected. To determine the need, capillary rise and moisture contents were measured after the wicks were cleaned by four methods : combustion, acetone extraction, detergent washing, and uncleaning. The wicks were made with fibers produced by PPG Industries and Manville Company, U.S.A. Results showed that wicks made from PPG fibers lost up to 3.4% of original mass during combustion while Manville fiber wicks lost only up to 0.6%. These losses are assumed to have been due to combustion of organic compounds applied by the manufacturers. All cleaning methods had higher capillary rise than obtained with uncleaning method Combustion at 40$0^{\circ}C$ for 4 hours was the best cleaning method. removing 98 to 100% of impurities.

In this paper, vertical earth pressure by CANDE program is compared with that by some equations such as the equation by Janssen, Marston, Spangler, and Handy to calculate vertical earth pressure with respect to several factors acting on a rigid buried-pipe filled cohesionless soil. As a result of comparative analysis of vertical earth pressure with each equation, primary factors are affected by backfill width, backfill depth and wall friction. Moreover, vertical earth pressure is linearly increased with backfill depth and width from results of the finite element method. Handy's Equation is reasonable for finite element method while Marston equation is overestimated in case of the design of buried-pipe and box.
