Developments toward a 'the end of the Cold War' are the main factor determining the situation in the Korean Peninsula. While all the combat resources of North Korea are systematically controlled and kept available for instant mobilization even in peacetime. South Korea is inferior to North Korea in terms of mobilization system and efficiency, exercise intensity and equipments. In sum, the South faces far greater restraints in wartime conversion capability than does the North. Mobilization refers to a nation's compulsory control, management and operation of its human and material resources for the purpose of national security. The total capability for safeguarding national security must be pursued by the continuous examination and complementation of our mobilization system and capability. This paper proposes an efficient management of national mobilization system that can be instantly operated on the whole in time of national emergency. Therefore, the actual operation of National Security Council is suggested to prepare operations against the emergencies and establish the foundation for national security.

With the advancement of artificial intelligence and its various use cases, accessing it through edge computing environments is gaining traction. However, due to the nature of edge computing environments, efficient management and optimization of clusters distributed in different geographical locations is considered a major challenge. To address these issues, this paper proposes a centralization and automation tool called KubEVC-Agent based on Kubernetes. KubEVC-Agent centralizes the deployment, operation, and management of edge clusters and presents a use case of the data transformation for optimizing intra-cluster communication. This paper describes the components of KubEVC-Agent, its working principle, and experimental results to verify its effectiveness.
Efficient financial management is a critical factor in achieving school foodservice goals. The objective of this study was to suggest efficient financial management practices in secondary school foodservices. In pursuit of this objective, we first identified performance indexes for measuring the success of financial management. Second, we suggested financial management standards, financial data classification methods and a report system. Last, we analyzed operating ratios with the financial data of self-operated and contract-managed school food services. The data were collected through an open-ended questionnaire from 10 middle/high school foodservices in Seoul and Kyeonggi Provincial during on-sites visits and interviews with dieticians and managers. Student participation, sales goals, re-contract frequency and number and cost of disaster loss were identified as the performance indexes for financial management. Income statements were compiled by identifying and classifying financial data. Total revenues consisted of subsidies, meal sales, other revenue and interest. Expenditures consisted of purchased food, salaries and wages, utility costs, office supplies, kitchen supplies, purchased services, company overhead indirect costs, facility investment and maintenance, facility usage expenses, employee benefits and miscellaneous. Mean price of a meal was 2,326 won at self-operated foodservices when the subsidies were included as revenues and 2,360 won at contract-managed foodservices. When including the subsidies as revenues, the operating ratios of self-operated foodservice showed that the food cost percentage was 66.9%, labor cost 23.2%, operation cost 9.9% and profit 0%. The correspond figures at contract-managed foodservices were 57.6%, 21.5%, 15.3%, and 5.5%, respectively. Food costs in self-operated foodservices was significantly higher than that for contract-managed foodservices, however, facility investment and maintenance and facility usage expenses at self-operated foodservices was significantly lower than those for contract-managed foodservices. Based on this study, the methodology and classification system of financial data was found to be applicable to assess the financial structure of school foodservices.
1. The Purpose of This study research: The focus of marketing until recently has simply been on sales which means the transfer of goods from the producer to the consumer and on profits therefrom. However, the excess supply of goods due to the expansion of the economy and the resulting fierce competition between companies have changed the nature of marketing. Maximizing consumers' satisfaction and establishing marketing mix strategies for market subdivision and penetration into the target market are now significant roles of the marketing manager. In addition, with regard to company management, information within the company which had been collected, managed and processed sporadically indegrated manner. The purpose of this research on marketing information systems in connection with the above will be to seek ways enabling us to create an efficient and integrated information system for an entire company. 2. The Method and Scop of This Stdudy: Marketing information systems, as a part of management information systems, shall be examined based on relevant theoretical literature. The research process shall be generally developed as follows: 1) The basic structure of the marketing information systems, including its fundamental purpose and necessity, shall be examined. 2) The method for a specific plan shall be presented through fundamental marketing strategy concepts and marketing decision-making. 3) A general model shall be presented based on examinations of various mod els used for marketing information systems and on research of the models' relationship with management information systems. 4) The direction of development shall be presented as the basis for gradual development following examination of the scope, pertinent issues, and means of improvement of the marketing information systems. 3. Summary and Conclusion: As the competition among the enterprises has become keen and thus the management of the contemporary enterprises shows the tendencies of uncertainty as well as complexity, all the managers must make the correct and prompt decision of their mind. Otherwise, the danger which will lead to and failure in the failure in the business may befall to the enterprise. Though computer system and information related techniques have the endless potentiality for the improvement of the enterprise, those are granted only to the enterprise which will be able to manage the computer system and information related techniques. In the contemporary industrial society, the need to a managerial information system has been increasing because all the complicated information can be stored, disposed and managed by the efficient method. And the marketing information system is also the integrated system which has been formed and developed through the efficient mixture of all the constituent elements including the definition of marketing research as the definition of the information system has been enlarged due to the reason shown above. The common point of the two systems is the man machine system functioning to help the efficient decision of the mind by introducing the computer system on the basis of user manager centered thought in order to provide informations to be useful in operation and management of the organization and the function of the mind decision. The purpose for the marketing information system lies in making the utmost use of marketing information available in the course of the mind decision. The reason why the contemporary enterprises necessitate the marketing information system are as follows: 1) The stages of the business operation are expanded wide to the world. 2) As the living standards of the consumers have been on the rise, the enter prise has to satisfy the consumer's "wants" than simple "needs".
This study was conducted to identify the problems related to operation of the committee system in university hospitals and to propose the direction for reforming it. Data were collected by surveying 138 working-level administration managers of committees from 12 university hospitals in Seoul in October, 1995. The results were as follows: 1. The purposes of the committee were to promote the reasonable dicision making in the hospitals, to satisfy the requirement of Hospital Accreditation Program and, to execute the administrational instructions in due order. The sort of job which was charged of chairmen and the majority of committee member was doctor. 2. The committees which were to be held the meeting frequently in a year were general management committees(8.25 times/year). But in case of operation rate, medical care-related committees showed the most frequent meeting(90.15%). Most of committees made the regulations and reported the results of their meeting to the CEO of their hospitals by written documents. 3. Most doctors thought the medical care-related committees useful. Medical technicians regarded education and research-related committees as useful, while administrators favored the general management committees. 4. The factors related to the perceived performance of the committee were the kind of job, the class of job and the kind of committee. Also, the perceived performance of the committee was positively related to the usefulness in efficient management of work, and negatively to uncertainties in responsibility and a nominal role of the committee. 5. Most of the respondnts thought that the concern of the top manager about the committee was the most important factor for the improvement of committee system at hospitals. They also regarded that formalization of the objectives and regulation rule and composition of committees with members which work in various fields as essential. Further studies on the organizational and operational cjharacteristics which include general hospitals in various areas are required.
Recently, natural disasters caused by climate change have become more frequent across the world. Our country is also not exceptional, and it is urgent to come up with appropriate measures in the agricultural sector as the size and intensity of drought are becoming severe. Consequently, the Ministry of Agriculture and Food has continuously raised the need for efficient water management and governance to overcome the periodic drought. Thus, there is a need for water-saving education and water conservation governance for sustainable and efficient use of agricultural water. Governance is a cooperative mechanism involving various stakeholders, such as central, local, civil society, and businesses, to solve regional or social problems, with different definitions and concepts depending on the field or scope. In this study, we aim to present basis of a governance framework for direct water management participation involving the key agricultural water use stakeholders to imbibe the culture of water savings and conservation practices. Based on this, water-saving governance was established and operated in Gyeongju and Yeoju, in South Korea as a 'water conservation practice', while the water management status of local farmers, the reliability and importance of stakeholders, and the need for governance were investigated. The results indicate that the involvement of various stakeholders in the governance of water management yielded water-saving effects. This study provides the directions of making a framework for water-saving governance establishment and operation. It is expected that sustainable agricultural water use can be achieved in response to climate change if the governance builds and operates with agricultural water use stakeholders based on the continuous government supports.
The product lifecycle of a marine vessel can be classified into the design-production, operation-maintenance, and disposal phases. During the operation and maintenance phase, status data should be gathered from the major machinery and instruments installed on the marine vessel in order to perform efficient maintenance work. Although a PLM (product lifecycle management) system can manage the product information during the design and assembly stage, a PLM based on asset management technology is more appropriate for product information management during the operation stage. Product embedded information devices (PEIDs) are suggested for gathering real-time maintenance information during the operation and maintenance lifecycle. A PEID allows PLM to provide the capability of offering active information exchange between the lifecycle management system and equipment. This study designed a PEID to effectively obtain information and interact with a PLM system. It consists of sensors, wireless communication, and a micro-processor, which allow it to accumulate status data on the PLM system. The embedded information device and PLM enable the seamless information flow, tracking, and updating of MRO (maintenance repair and overhaul) information for a product throughout the middle of the product lifecycle.
