The need for education and training on engine-part maintenance is rising in order to prevent marine accidents occurring due to a surge in engine-part damages. However, practical training using actual equipment is difficult due to the size and location of the equipment. Therefore, the necessity of developing a training system for marine engines using virtual reality (VR) is intensifying. The purpose of this paper is to develop an optimized system for marine engine education and training using existing VR programs and equipment. To this end, we selected and modeled the marine engine and education target suitable for the class, and developed the system using VR development software. The developed VR education and training system is designed to experience content that is otherwise difficult to train or practice in the curriculum through virtual reality. In fact, fourth grade students from Maritime University were taught using marine engine VR educational equipment, and it confirmed that there was an educational effect on the class. In the future, the introduction of an education and training system using VR in the field of marine engines can improve their maintenance and repairing capacity, and aid in reducing marine accidents.need for education and training on engine part maintenance is increasing to prevent marine accidents.

The spread of COVID-19 has caused confusion in the education field as it has led to the implementation of untact classes without preparation. The purpose of study is to find ways to effectively design and operate untact classes for tax accounting department. The survey and FGI were conducted on professors and learners. As a result, video classes through lecture shooting and PPT-based video conversion were the most utilized. Students prefer these two types most, because they can learn repeatedly regardless of time and space. The improvement measures are as follows. For video classes that reflect various characteristics of the subject, supporting for equipment and human resources is needed, and for professors, teaching support for untact classes and education on equipment manipulation is needed. Continuous Quality Improvement for untact classes should be overhauled. In the future, in-depth research is needed to various majors, this will help find ways of untact classes suitable for the characteristics of the subjects.

The river environment in Korea has changed significantly after the completion of the Four Major Rivers Project due to the outdated river management methods and thus, it is necessary to modify the current river management process. A typical example of this management is dredging but it is a method that usually results in socio-environmental side effects. Therefore, in order to minimize the socio-environmental impacts of dredging, Korea is currently applying the Environmental Windows, a management practice currently being used in the United States that eliminates the risk of potentially harmful impacts of dredging. The use of statistical methods was suggested to address the issue of data insufficiency and this methodology was applied in the downstream part of the Gangjeong-Goryeong weir located within the Nakdong river basin. The results show that when performing a month of dredging, the optimal period is March whereas the optimal month to start dredging is August in case of an eight-month dredging project. If Korea's flood season is also considered for an eight-month dredging process, then October is the optimal month to start dredging. Non-structural methods such as the Environmental Windows reduce maintenance costs and also bring only short-term side effects to the environment, as opposed to structural methods such as the development of environmentally-friendly dredging machine. Given that few studies have explored this topic in Korea, the findings and suggestions could serve as basic data in studying river dredging in the future.

This research shows solutions for relieving the reversibility of the VAT system, and the solutions will be reviewed with current issues about supporting welfare. The Followings provide practical implementing solutions for each issue. Since the VAT is taxed for all goods and services as a general consumption tax, it is efficient tax policy for resource allocation comparing to income tax. On the other hand, because of the reversibility of the tax burden is also treated as a non-effective tax system for fair taxation. Even it is a non-effective tax system, the VAT system takes the most portion from the total national tax. In South Korea economic system, it is hard to raise the VAT rate because the economic effects are tremendous. For the long-term, the possibility of increasing the VAT rate is unavoidable, considering the economy, society, environment and energy, and aging. Therefore, a variety of substituted policies for the reversibility should be covered once there is a conference for the increase in the VAT rate. This research provides foundational solutions by acknowledging the reversibility of the tax burden in terms of the effective value-added tax rate. The followings are four solutions. First, it is required to adjust the duty-free system for relieving the reversibility and expand the tax-free system as well as individual consumption tax items. Second, The relief of reversibility should be worked by imposing higher the tax rate for high-income people' goods and services. Third, the adjustment of the duty-free system could be considered due to relieve the reversibility of the VAT. Last, it is considered to adjust of the simplified taxation system because the simplified taxation system is seriously against the tax-transfer principles.

Many preliminary entrepreneurs are ready to start a business in every year. However, starting and preparing business have a lot of difficulties. Entrepreneurship is the most important factor for overcoming these difficulties. But, it is not easy to understand entrepreneurship to founders despite many research scholars. In this paper, we are focused on easy understanding of entrepreneurs. Instead of vague theories, we analyzed selected two companies in Korea. From the beginning until now, these companies have founders entrepreneurship and organization entrepreneurship. we studied these entrepreneurship factors with other Various causes. Analysis of two cases is summarized into three type. First, both companies had well-founded internal network system. Trained employees in internal network were flexible to meet the market conditions. Also, network effect made that employees can offer their idea and make discussions. Second, The company quickly recognized for organizational culture despite of most other companies recent awareness. This factor was the basic driving force for solving human resource management problem of small size companies. final factor is innovation capacity of these companies. Financial difficulties experienced of establishment is common to every company. However, two companies has continued to invest research and development despite of this financial problem. As a result, intellectual property management was accepted, as well as technology development. Clearly, these three factors are consistently applied since established and led to the company's continued growth and success.

이 연구는 1990년대 이후 헝가리 농촌지도의 특징적인 변화를 고찰하였다. 헝가리의 농촌지도사업은 오랜 역사를 가지고 있으며 주로 대규모 농장을 대상으로 한 농업기술전파에 주력하였다. 1990년대 이후 사유재산의 인정과 시장경제체제로의 전환과 함께 시장에서의 경쟁력이나 지속성에 대한 요구는 농촌지도사업의 방향전환을 요구하게 되었다. 유럽연합의 농업정보시스템 표준화에 요구와 헝가리 내의 농산업구조의 변화는 농업정보시스템 구축의 필요성을 낳게 되었다. 헝가리에서 농업정보시스템의 개발은 농업경제연구정보원(AKII, Research and Information Institute for Agricultural Economics)과 중앙통계사무소(Hungarian Central Statistical Office)에서 이루어졌다. 시스템 개발의 주요 분야는 농업통계, 농장회계자료네트웍, 시장정보시스템의 세 가지이며 이들의 복합적인 농업정보시스템으로 형성되었다. 본 연구에서는 위의 세 가지 주요 범주의 개발배경과 진행사항, 문제점들을 살펴보고 개선방향을 제시하였다. 헝가리 농업 농촌개발부(The Ministry of Agriculture and Rural Development)의 최근 정책의 특징은 전국적인 농촌지도상담 네트웍의 구축이라고 할 수 있다. 현재의 헝가리 농촌지도사업체계는 크게 세 부분으로 나누어 볼 수 있다. 첫째 농업농촌개발부의 군사무소는 지역사회의 독농가나 선도농가와의 밀접한 관계를 유지하며, 이러한 독농가나 선도농가로 하여금 지역의 농민들에게 도움을 줄 수 있도록 하는 것이다. 둘째는 민간 자문가들이 농장을 방문하여 현장에서 농민들에게 전문적인 도움을 주도록 하는 것이다. 민간 자문가들은 도 단위의 전문지도사들로부터 정보나 기술에 대한 전문적인 도움을 받는다. 세 번째는 전문교육기관을 통한 농민들에 대한 직접적인 교육이다. 이러한 교육들은 농민들에게 무료로 제공되며, 교육과정이나 프리젠테이션, 전시 등을 통해 이루어진다. 현재 헝가리 농촌지도체계는 그 실행과정, 효율성, 조직적인 면에서 완성되지 못하였고 전환기에 처해 있다. 효율적인 농촌개발을 위해서는 농촌지도상담의 효과나 조직면에서 많은 연구와 정비가 필요한데 이는 헝가리의 국가적 이익의 증대와 유럽연합의 목적에 부합하기 위해서도 적극적인 관심과 노력을 필요로 하는 분야이다. 이러한 필요성을 바탕으로 농촌지도사업의 새로운 모델을 제시하면, (1) 수도인 부다페스트에 농촌지도사업을 전반적으로 책임지는 중앙부서를 설립하여 효과적인 농촌발전을 지원하여, (2) 7개의 도에 농학계 대학과 연구소를 중심으로 하는 지역센터를 설립하여 도내의 농촌지도상담활동과 영농에서 농업관련 사안에 대해 문제해결 중심의 도움을 주도록 하며, 지역센터는 자율적, 독립적으로 운영하도록 하고, (3) 50여개의 군에 일선지도기관을 설립하여 농업인들이 쉽게 방문할 수 있도록 하며, 지역의 특수한 상황이나 사안에 대해 융통성 있게 대처할 수 있도록 하는 것이다.

Recently, our company has entered the modern knowledge company, government policy and regulation has a big influence on people's lives. Also, unlike in the past, I am hoping for administrative intervention as a problem peculiar to the environment, such as environmental housing problems, urban transportation problems, misuse problems, etc. and corporate pending issues. In this study, through the 10th year of the Seoul Special Citizen Judicial Police Force, if the local autonomy is a special envoy, it will try to present the correctness in the organization luck. As a measure to secure the nature of administrative action, the method of investigation was through the study of the execution process of administrative penalty and its result based on the statistical data of Seoul City. Therefore, we will analyze the process and operation of the 10-year organizational change of the Seoul Metropolitan Government's police force and examine how the police force of the people's livelihoods, which is a special investigation organization, is expanding its duties in order to strengthen the enforcement power of the administration. Also, we will make future-oriented suggestions to encourage the readjustment of the current relevant laws, such as the Ministry of Patriots and Veterans Affairs, and to actively accommodate the expected changes of the special law police organization in charge of the enforcement of the police system.

Disaster is when, where, and how uncertainties, which might occur. Thus, for disaster response and management at the national and local governments have been made. Korea has established the Disaster and Safety Management Basic Act. Disaster Management has been made at the national level which is to prevent disasters and countries in order to protect citizens from harm and dangerous. Korean Disaster management system is well equipped with advanced countries. The Organization of national and local government are well-maintained substantially for the disaster activities and step-by-step manuals activities. Despite that uncertainty, due to the nature of the disaster, while infrequent, causing large-scale tragedy. Minimize the damage of the disaster as a disaster management efforts are needed. Normally a real disaster, a disaster situation, efforts are to be utilized efficiently, the effectiveness of the system will appear. But while the number of large-scale disasters, including the sinking of Sewol this time for the government and local governments see the response process, the system did not work and the manual existed in the cabinet. There was no Prevention and preparation activities, there was no integrated organization for the response management with expertise in the professional staff. Whenever a large disaster raised repeatedly as a problem, but there was a substantial change in formal but no improvement. It will not reduce the damage if the disaster management is not prepared for a revolutionary turning point.

Recent domestic use of radiations has increased in the number of institutions and companies as well as operating as an investment, a variety of facilities and safety management are becoming increasingly complex. Despite the increase of radiation workers and facilities, the number of RSOs (Radiation Safety Officers) has not increased with a growing domestic radiation industry. The radiation safety management work (radiation workers management, radiation sources management, facilities management etc.) has been managed by insufficient number of the RSOs. These problems could be directly or indirectly related to causes of the radiation accidents. In this paper, we designed the Process Mapping of radiation safety management work for an efficient safety management of the radiation facilities and protection of radiation accidents. To develop the Process Mapping, we analyzed the radiation safety requirements of management issues and the individual procedures. Based on the Process Mapping, the work procedures for an appropriate radiation safety management of each institution can be configured clearly. Through this procedures, the safety risk factors in radiation facilities can be reduced, and the radiation safety management system will be improved. Depending on your needs, the Process Mapping could be modified and could be used for an efficient radiation safety management.

The construction standards in Korea consist of design standards and specifications. They are provided by the national transportation electronic information center in file format, not in a DB, which may lead to their incomplete utilization and versatility, such as a lack of history management and reference functions. This also makes it difficult to cross-refer to standards and manage revision history. In this study, we developed a code management system for the national construction standards by analyzing domestic and overseas related systems, in order to pinpoint the problems in the current system and its development direction and, thus, to suggest a detailed plan for the design and implementation of a code management system. The developed system comprises four subsystems, namely a construction standards making system, construction standards service system, construction standards maintenance system and construction standards portal system. The results of this study are expected to improve the user's convenience by facilitating the revision, operation and history management of the complex and various construction standards, and to provide high-quality national construction standards by effectively supporting the revision and operation of the national construction standards with minimum duplication and conflicts.
