This paper describes empirical approach methodology for the quantitative risk assessment of maritime transportation accident (MTA) of a merchant ship. The principal aim of this project is to estimate the risk of MTA that could degrade the ship safety by analyzing the underlying factors contributing to MTA based on the IMO's Formal Safety Assessment techniques and, by assessing the probabilistic risk level of MTA based on the quantitative risk assessment methodology. The probabilistic risk level of MTA to Risk Index (RI) composed with Probability Index (PI) and Severity Index (SI) can be estimated from proposed Maritime Transportation Accident Model (MTAM) based on Bayesian Network with Bayesian theorem Then the applicability of the proposed MTAM can be evaluated using the scenario group with 355 core damaged accident history. As evaluation results, the correction rate of estimated PI, $r_{Acc}$ is shown as 82.8%, the over ranged rate of PI variable sensitivity with $S_p{\gg}1.0$ and $S_p{\ll}1.0$ is shown within 10%, the averaged error of estimated SI, $\bar{d_{SI}}$ is shown as 0.0195 and, the correction rate of estimated RI, $r_{Acc}$(%), is shown as 91.8%. These results clearly shown that the proposed accident model and methodology can be use in the practical maritime transportation field.

This paper deals with the novel concept of neo-endogenous rural development which has been applied to explain the contemporary features of the European rural development. The notion of neo-endogenous rural development has been emerged in Europe because the pervious dichotomous concepts of exogenous and endogenous development are no longer useful for explaining the relationship between the local actors and the central or regional administrative organisations. The concept argues that the changing situation of rural regions at the initial stages of endogenous development could only be identified by the concept of neo-endogenous perspectives. Therefore, it tries to apply the concept for the Korean rural development policy which is called Regional Agricultural Cluster scheme. Explaining the development processes and the problems of the farmers group which carried out the project in a local level, this paper argues that the severe conflict between the farmers group and the City Office may be a typical incident of the neo-endogenous development. It expresses the power relations between the local groups and the political managing authority. With the case of the Prundle, it concludes that the neo-endogenous development is the essential stage for all the endogenous development to go through as an transitional one.

Poor logistical infrastructure and agri-food supply chain management leads to significant food waste in logistic system. The concept of the sustainable value added agri-food chains requires defined approach to the analysis of the existing situation, possible improving strategies and also assessment of these changes impact on further development. The purpose of research is to provide scientific substantiation of theoretical and methodological principles and develop practical recommendations for the improvement of the agri-food logistics distribution system. A case study methodology is used in this article. The research framework is based on 4 steps: Value Stream Mapping (VSM), Gap and Process Analysis, Validation and Improvement Areas Definition and Imitation Modelling. This paper presents the appropriateness of LEAN logistics tools using, in particular, Value Stream Mapping (VSM) for minimizing logistic losses and Simulation Modeling of possible logistics distribution system improvement results. The algorithm of VSM analysis of the agri-food supply chain, which involves its optimization by implementing the principles of sustainable development at each stage, is proposed. The methodical approach to the analysis of possible ways for optimizing the operation of the logistics system of the agri-food distribution is developed. It involves the application of Value Stream Mapping, i.e. designing of stream maps of the creation of the added value in the agri-food supply chain for the current and future state based on the minimization of logistic losses. Simulation modeling of the investment project on time optimization in the agri-food supply chain and economic effect of proposed improvements in logistics product distribution system functioning at the level of the investigated agricultural enterprise has been determined. Improvement of logistics planning and coordination of operations in the supply chain and the innovative pre-cooling system proposed to be introduced have a 3-year payback period and almost 75-80% probability. Based on the conducted VSM analysis of losses in the agri-food supply chain, there have been determined the main points, where it is advisable to conduct optimization changes for the achievement of positive results and the significant economic effect from the proposed measures has been confirmed. In further studies, it is recommended to focus on identifying the synergistic effect of the agri-food supply chain optimization on the basis of sustainable development.

Korea was highly successful in maintaining a strong tradition of record preservation. However, Japanese imperialism and the Korean war over this century has seen a huge quantity of these once plentiful records either destroyed or relocated overseas. Many of Korea records remain in the custody of foreign archival institutions. Additionally, many records of foreign states concerned with korean affairs, for example, records of the Department of state, in the U.S.A., are of great relevance to Korean modern history. These records which exist in foreign countries are a necessary and invaluable resource in the advancement of Korea studies. After the 1980s, as research interest in Korean modern history increased gradually, much historical material related to Korea was extensively introduced, removed, collected from the U.S.A., Japan, Russia and China etc. by the efforts of pioneering scholars and institutions. Several attempts at collating and publishing this material have been made. Despite this encouraging result, individual scholars and institutions's efforts face problems in relation to removal of records. Firstly, it is repeated nonproductively to remove and collect the same records, for we didn't establish a comprehensive information system, through which the condition of foreign record removal and management is able to be administrated. Secondly, there is no system for arrangement, preservation, use of removed records. For example, finding aids, such as inventory, register, description, isn't prepared for user. A user may usually not understand an accurate context of their creation, preservation removal. Thirdly, almost institution has arranged the removed records among other materials and books. Each institution has a different classification criteria, too. These conditions seem to make a difficulty in national management. This study investigated how the materials for Korea history which has been removed from foreign countries should be managed for effective preservation and use. For these purpose, we investigated the present conditions of removal and management of these materials. Also, we investigated examples of the foreign state, U.S.A. and Japan to have a idea for removal and management policy. Then, This study propose a establishment of information network system as management policy. To administrate removing and managing records effectively, an idea that records belong to the public should be accepted commonly. The policy for management of the record is followings. Firstly, unification of classification is necessary. The records which were removed from foreign countries had better to be classified according to their origins of states and institutions. Secondly, Finding aids should be prepared for user. There are many accession aids such as catalog, register, inventory for user in archives. This will be a efficient method for management. When a record is removed, a card for description of contents must be composed. Thirdly, a digital input and network system establishment is necessary. It will help to manage a condition of removed records. A digital input and management system establishment is not just a project of digitalizing records. At present, various finding aids need to be introduced to make a database for records and archives. An search using only 'search engine' may make a difficulty in finding materials because such method is apt to have too much or little result. So, classification, arrangement, description, response-service should be integrated in these system. The recent technical advancement give a opportunity to realize this idea. Above all, these procedure should be archival process.

The Under Space Integrated Map has been constructed consistently from '15 construction projects until the present time in an effort to implement the "ground sinking prevention method" for the purpose of strengthening underground safety management. The constructed Under Space Integrated Map is utilized to provide information to the person in charge at local government through application of the system of underground information based on the administrative network and to deliver this to specialized underground-safety-effects -evaluation organizations through map extraction based on a floor plan. It suffers from a limitation in its practical use, however, since information is only provided, without promoting a separate renewal project. Although in Section 1 of Article 42 in the Special Law Concerning Underground Safety Management the content pertaining to submission obligations of completion drawings related to underground information including change and renewal are stated explicitly in order to solve this problem, submission is not sufficient since a submission window based only on the administrative network is operated. Accordingly, the Ministry of Land, Infrastructure, and Transport constructed an online system for submitting completion drawings, in an attempt to change the method by which entities involved in underground development directly submitted completion drawings. In this study, a DB standard relating to submitting completion drawings was designed and applied in order to construct an auto-renewal system based on submitted completion drawings, which will be extended to cover the range to underground structures hereafter.

Even in an era where 8-meter class telescopes are common, small telescopes are considered very valuable research facilities since they are available for rapid follow-up or long term monitoring observations. To maximize the usefulness of small telescopes in Korea, we established the SomangNet, a network of 0.4-1.0 m class optical telescopes operated by Korean institutions, in 2020. Here, we give an overview of the project, describing the current participating telescopes, its scientific scope and operation mode, and the prospects for future activities. SomangNet currently includes 10 telescopes that are located in Australia, USA, and Chile as well as in Korea. The operation of many of these telescopes currently relies on operators, and we plan to upgrade them for remote or robotic operation. The latest SomangNet science projects include monitoring and follow-up observational studies of galaxies, supernovae, active galactic nuclei, symbiotic stars, solar system objects, neutrino/gravitational-wave sources, and exoplanets.
