This study is to develop a diagnostic model for the effective introduction of smart factories in the manufacturing industry, to diagnose SMEs that have difficulties in building their own smart factory compared to large enterprise, to identify the current level and to present directions for implementation. IT, AT, and OT experts diagnosed 18 SMEs using the "Smart Factory Capacity Diagnosis Tool" developed for smart factory level assessment of companies. They analyzed the results and assessed the level by smart factory diagnosis categories. Companies' smart factory diagnostic mean score is 322 out of 1000 points, between 1 level (check) and 2 level (monitoring). According to diagnosis category, Factory Field Basic, R&D, Production/Logistics/Quality Control, Supply Chain Management and Reference Information Standardization are high but Strategy, Facility Automation, Equipment Control, Data/Information System and Effect Analysis are low. There was little difference in smart factory level depending on whether IT system was built or not. Also, Companies with large sales amount were not necessarily advantageous to smart factories. This study will help SMEs who are interested in smart factory. In order to build smart factory, it is necessary to analyze the market trends, SW/ICT and establish a smart factory strategy suitable for the company considering the characteristics of industry and business environment.

Recently, as weapon systems have become more complex and multi-functional, the difficulty of the operation and maintenance of weapon systems in the military have become increasingly difficult. On the other hand, the service period of operations and maintenance workers who perform operations and maintenance has been shortened, and the skill of system operation and maintenance has been lowered. This complexity and multi-functionality of equipment cause malfunctions and errors of users and maintenance personnel, and degradation of the reliability affects availability and combat readiness. In addition, life cycle costs have been gradually increasing. Therefore, I would like to suggest an improvement plan of the design of weapon systems and ILS (Integrated Logistics Support) in order to examine the implications of failure in the military. The weapon system is operated in the ROK Navy. Data from 730 cases of failure of weapon systems was collected, and analyzed. The results of the analysis are classified into failures that can be prevented in advance and failures that cannot be prevented. This shows the portion of preventable failures in weapon systems and proposes measures to minimize failures.

Safety is essential for organizations operating in high-risk environments, such as the Navy. Effective safety management requires continuous improvement and supplementation, commonly achieved through the PDCA (Plan-Do-Check-Act) cycle. Despite reinforced safety regulations and expanded education, safety accidents persist in the Navy, indicating a need to enhance the safety accident analysis and classification system. This study aims to analyze and identify the shortcomings of the current Navy safety accident classification system to establish a more effective framework. By doing so, we will be able to register the results of safety accidents, identify their root causes, and propose a 12-digit Navy safety accident classification code. This code will contribute to the development of mid- to long-term safety management policies.

The dynamic nature of mechanization and automation to improve productivity and safety within logistics centers, has necessitated various studies to support efficient and safe working conditions for workers. However, accidents in the loading dock occur frequently as workers and forklift trucks operate within the same space. This research introduces cargo batch loading and unloading systems, which enable increasing productivity and safety through the use of mechanization and automation in the loading dock. To assist efficient operation of this new system, four pieces of general-purpose equipment or three pieces of dedicated equipment are deemed to be essential. Moreover, the floor area of the loading dock is designed to accommodate $256.28m^2$ and $207.00m^2$ for the general-purpose and dedicated systems respectively, in addition to the space allocated for equipment and additional space. The design of the loading dock considers the area of the loading dock as well as the cargo batch loading and unloading systems. Economic analysis, such as NPV, IRR, and PBT, were conducted in addition to sensitivity analysis on key variables.

As the revitalization of the global maritime industry continues, the number of foreign ships navigating the maritime territories of maritime neighboring countries has rapidly increased. However, large-scale marine accidents have occurred, caused by the insufficient establishment of a system for management and operation relative to vessels' safety-condition. To address that, the IMO has granted the right to exercise port state control, especially for foreign vessels, to countries with jurisdiction over maritime territories with strengthening regulations and guidelines. In particular, the Republic of Korea, as a member of the TOKYO MOU, is conducting PSC, but as of 2020, the proportion of foreign ships was three times higher than that of national ships that called in domestic ports. However, the inspection rate was low at 9% which has not met the recommended level by the TOKYO MOU. Thus, this study conducted an IPA analysis as well as content analysis, by collecting the practical opinions and views of PSCO through objective questionnaires and written expert interviews, for improving the efficiency and effectiveness of domestic PSC. As a result, it was derived that the importance and performance related to human factors such as life on board, working environment, and response to safety accidents should be improved in to raise the quality of PSC inspection. Additionally, the work environment and performance of PSC in domestic ports for foreign vessels could be improved, if multifaceted support bases are established, for administrative unification of related tests for PSC, recruitment of PSCO, activation of the defection-reporting system, reorganization of the PSC execution group, etc.

The National Defense Reformation bill of "National Defense Reformation 2020" which have been constantly disputed and reformed by the government went through various levels of complementary measures after the North Korean sinking on the Republic of Korea (ROK) Naval Vessel "Cheonan". The final outcome of this reform is also known as the 307 Plan and this was announced on the 8th March. The reformed National Defense Reformation is to reduce the number of units and military personnel under the military structure reformation. However, in order for us to undertake successful National Defense Reformation, the use of privatized civilian resources are essential. Therefore according to this theory, the ROK Ministry of National Defense (MND) have selected the usage of privatized resources as one of the main core agenda for the National Defense Reformation management procedures, and under this agenda the MND plans to further expand the usage of private Especially the MND plans to minimize the personnel resources applied in non-combat areas and in turn use these supplemented personnel with optimization. In order to do this, the MND have initiated necessary appropriate analysis over the whole national defense section by understanding various projects and acquisition requests required by each militaries and civilian research institutions. However for efficient management of privatized civilian resources, first of all, those possible efficient private resources which can achieve optimization will need to be identified, and secondly continuous systematic reinforcements will need to be made in private resource usage legislations. Furthermore, we would need to consider the possibility of labor disputes because of privatization expansion. Therefore, full legal and systematic complementary measures are required in all possible issue arising areas which can affect the combat readiness posture. There is another problem of huge increase in operational expenses as reduction of standby forces are only reducing the number of soldiers and filling these numbers with more cost expensive commissioned officers. However, to overcome this problem, we would need to reduce the number of positions available for active officers and fill these positions with military reserve personnel who previously had working experiences with the related positions (thereby guaranteeing active officers re-employment after completing active service). This would in tum maintain the standards of combat readiness posture and reduce necessary financial budgets which may newly arise. The area of maintenance, supply, transportation, training & education duties which are highly efficient when using privatized resources, will need to be transformed from military management based to civilian management based system. For maintenance, this can be processed by integrating National Maintenance Support System. In order for us to undertake this procedure, we would need to develop maintenance units which are possible to be privatized and this will in turn reduce the military personnel executing job duties, improve service quality and prevent duplicate investments etc. For supply area, we will need to establish Integrated Military Logistics Center in-connection with national and civilian logistics system. This will in turn reduce the logistics time frame as well as required personnel and equipments. In terms of transportation, we will need to further expand the renting and leasing system. This will need to be executed by integrating the National Defense Transportation Information System which will in turn reduce the required personnel and financial budgets. Finally for training and education, retired military personnel can be employed as training instructors and at the military academy, further expansion in the number of civilian professors can be employed in-connection with National Defense Reformation. In other words, more active privatized civilian resources will need to be managed and used for National Defense Reformation.

In recent years Mag-Geol-Li is becoming popular again and the consumption layer of Mag-Geol-Li is definitely younger. Nowadays, Mag-Geol-Li is the main traditional alcohol and without consideration of ages and genders whoever can enjoy Mag-Geol-Li. Producers should ensure fair price of goods and improve production facilities to maximize products to meet the needs of consumers who will buy. In the studies I discuss about the ways to improve the distribution of Mag-Geol-Li, the theories about Mag-Geol-Li, Social backgrounds and effects of Mag-Geol-Li why it is becoming popular and improvement of the distribution structure of Mag-Geol-Li and impact of big Mag-Geol-Li company in Mag-Geol-Li industry. Lately, people can enjoy Mag-Geol-Li without burden because of low alcohol. It is gaining a good response by consumers because Mag-Geol-Li contains lactobacillus, yeasts and dietary fiber, also it is well balanced with nutritional aspects. There are not only huge factory to produce Mag-Geol-Li but also most are still cottage industry. Therefore, quality management does not work well because the majority of Mag-Geol-Li is small businesses. In spite of there are a lot of ways to improve the distribution structure and problems of Mag-Geol-Li, but none provide any improvement that make consumer awareness about the main cause of the problem is inaccurate. The ultimate goal of improving the distribution structure of Mag-Geol-Li is activating the market, the improvement of production facilities and safe for consumers with affordable price and good quality product. As mentioned above, to improve and change the logistics systems and hygiene, government support is required and Mag-Geol-Li companies should be recognized the distribution system as a major problem.

RAM of elements to support weapon systems is conducted at the initial development phase and standard is suggested to accomplish strategy requirement performance from a design spec. Operational availability is a key point of the military's ability to ensure combat readiness and to win the battle. In the weapon system development phase, operational availability is used as a development standard. The military provides ALDT, operation and standby time, which are elements of operational availability. ALDT is a key element of operational availability that must be maintained for combat readiness, as it depends on the aging of a weapon system, maintenance policies and geographical conditions. Operational Availability to be set at the development phase has many differences from the operational availability that is analyzed in the actual operational phase because ALDT is applied as a simple assumption. In the paper, we analyzed ALDT applying the decision tree method through failure data acquired from initial operation. Through this study, we have devised the optimal ALDT setting method to achieve operational availability about operation when the weapons system is unstable.

This study discusses how transportation to connect railway stations in Korea's small and medium-sized cities can be improved, based on analysis of a survey on the Joongang Line. The analysis considered current problems in connectivity between parts of the Korean transportation system and suggests how to encourage more passengers to shift from private cars to railways. It was found that railway users in small and medium-sized cities hope for better connection between different modes of public transportation, especially for urban buses. However, there is not enough connectivity currently available; therefore it is crucial to establish a system of such connections, mainly focusing on urban buses. Furthermore, in order to minimize transfer distances and connect various transfer modes, plans for improvements of facilities are needed and governmental support should be provided.

Objectives: Promotion of food safety/eradicating adulterated food has been listed as one of the four major issues recently identified for action by the Korean government. Due to the related seriousness, the food industry has been encouraged to take steps to restore consumer confidence. In order to set guidelines for the creation of manuals for the response to a food safety crisis by the food industry, this study provided a suggested organization for a crisis response team and operating procedures for crisis response activities. Methods: The prototypes of an organizational structure and a set of standard procedures for a crisis response system were provided. Results: The results of the study suggested that a crisis response team should be comprised of four divisions of responsibility: information analysis, site response, communication and operational support. The organization chart and the role and functions for each division of the crisis response team should be indicated. Response activities will be more effective when the team features multi-disciplined staffing, such as public relations, food safety/technology/quality, sales/marketing, purchasing, production, distribution/logistics, regulatory affairs/legal, and consumer service specialists. This study created a flow chart for the total crisis response system, which included crisis and normal situations. A crisis response team should be continuously operated for both crisis and normal conditions. This study also suggested a scenario to explain the procedures for crisis response activities. Conclusion: In order to cope more effectively with a food safety crisis, the organizational structure and its functions should be defined clearly, and a detailed set of standard procedures for response activities should be offered.
