The purpose of the study was to analyze the apologies made in Korea for the past 10 years, and to diagnose how Koreans used crisis communication strategies. For the analysis, typology of crisis communication strategy was adopted from previous study as well as the new typology distinctively found in Korea. Also preferred crisis communication strategies were analyzed by crisis subject, by crisis type and by stage of crisis. Results showed that among the crisis communication strategies, apology and corrective action were the most used strategies, followed by bolstering and appealing to sympathy. Preferred crisis communication also differed by crisis subject, by crisis type and by stage of crisis. When the crisis subject were government or public institutions, when the locus of crisis responsibility was internal, and when the crisis was a controllable human/social crisis, the justification strategy was preferred. The results seemed to be related to the unique cultural characteristics of Koreans, especially to sense of Cheong and Chemyon. Indirect corrective action and transcendence were Chemyon-saving strategies while bolstering and appealing to sympathy were strategies appealing to Cheong. Future study should address the new typology of crisis communication strategy reflecting the cultural characteristic.

This study was conducted to derive the new manager model in service economy era. It was logically explained that the modern economic society is different from the existing economic society, the modern organization that is the subject of management is different from the existing organization, and the tasks required by management are different from the existing tasks. It suggested the managerial model required for new managers. According to the proposed manager's model, the tasks required of new managers and essential qualities as managers to perform the tasks were presented. It suggested the role model that managers with required qualities should play. The role of a manager who becomes one with customers, the role of a manager who controls even his irrationality, the role of a manager who combines discernment and indiscriminateness, a flexible leadership role that combines charisma and tenderness, an administrator role that embraces regulations and non-regulations, and vision and non-vision. We derived the role of a manager who manages management, and a manager role model that utilizes both competition and non-competition. The managers engage in two opposing roles and perform management activities in a spiral dialectical cycle that develops while resolving the contradictions of each role. The method of embracing the two opposing parties internally and externally and the dialectical management execution process according to the change of the space-time axis were presented by borrowing the models of The Book of Change. Future research needs an empirical analytical study on this new Model. There is a need for studies that expand this study and develop it into a practical model and verify it in an analytical way.

In the defense modeling and simulation, for the detailed analysis of the communication system, many studies have carried out the analysis under the C3 SoS(system of systems) which consists of C2(command and control) and C(communication). However, it requires time and space constraints of the C2 system. To solve this problem, this paper proposes a communication analysis method in the standalone system environment which is combined with the C system after abstracting the C2 system. In the abstraction process, we hypothesize the traffic model and mobility model for C system analysis and learn the parameters in the model based on machine learning. Through the proposed method, it is possible to construct traffic and mobility model with different output according to the battlefield. This case study shows how the process can be applied to the C3 SoS and the enhanced accuracy than the existing method. We expect that it is possible to carry out the efficient communication analysis against many experimental scenarios with various communication parameters.

The purpose of this paper is to find out the implications by studying the optimal mechanism for securing the supply chain competitiveness of manufacturing industries, especially steel-making company. To this end, this paper examined the case of affiliates of the representative global steel group in Korea. So far, research on corporate strategy has been mainly focused on the parent company of large group company, but this time, considering the strategic limitations and characteristics of affiliates of large group company, we will explore the mechanism of supply chain management on the basis of ser-M, and explore appropriate mechanisms for global steel makers and affiliates of large group company. As a result of this study, in affiliates of large group, parent company centered mechanism is easy to operate because many of the affiliates of large group companies are built by the needs of the parent company. Therefore, the mechanism that maximizes the controllable internal Resources from the affiliated companies' position appeared to be suitable. The study on ser-M based supply chain mechanism in this paper is meaningful in that it examines the mechanism focused on the case of supply chain management of global steel manufacturer. The significance can be found in the case study of affiliates. In addition, it is significant in that it is a case study of domestic representative large group affiliates.

Cybersecurity attack targeting a specific user is rising in number, even enterprises are trying to strengthen their cybersecurity. Network segmentation environment where public network and private network are separated could block information coming from the outside, however, it is unable to control outside information for business efficiency and productivity. Even if enterprises try to enhance security policies and introduce the network segmentation system and a solution incorporating CDR technology to remove unnecessary data contained in files, it is still exposed to security threats. Therefore, we suggest a system that uses file format conversion to transmit a secure file in the network separation environment. The secure file is converted into an image file from a document, as it reflects attack patterns of inserting malicious code into the document file. Additionally, this paper proposes a system in the environment which functions that a document file can keep information for incident response, considering forensic readiness.

In this study, the rate of return on investment used as a proxy variable for the entity's value and financial structure (liability ratio) is related to positive balance. This is consistent with the Static Tradeoff Theory (STT) that the entity's value and financial structure are related to a positive balance because the capital expense of a debt (tax-saving effects) that is less than its equity cost before it is in financial difficulty. Also, operating profitability (EBITDA/Sales), investment safety, total asset growth, net working capital and depreciation expenses are related to negative (-) with financial structure (liability ratio). This is the result of an analysis consistent with the Pecking Order Theory (POT). Fuel costs, borrowing, total asset turnover, financial costs, and tangible asset ratios have a significant positive relationship with the debt ratio. This is consistent with the agency theory and confirms that excessive chartering expenses, such as the bankrupt H company, are the main factors that pressure the financial structure of Korean ocean carriers.

The Demilitarized Zone (DMZ) stretches two kilometers north and south from the Military Demarcation Line (MDL) of South and North Korea. This area was established as a weapons-free buffer zone when an armistice agreement was signed in 1953. However, there have been several very high-tension military standoffss over the past 65 years. On the South Korean side, civilian access to the Civilian Control Line (CCL) and beyond to the north has been restricted, and natural heritage has been well maintained. Natural heritage is defined as living things, their habitat and non-living things of the ecosystem which deserve to be protected. Research shows that a variety of flora and fauna, their habitat, marshes and geographical structures are found across the DMZ region. Although the DMZ region has not been such a good place for habitat conservation, we can say that this area may be the best location for restoration in terms of its variety of ecosystems and considerable land size. Restoration of course depends on future plans and management policies. This area, including the DMZ and the well-protected north of the CCL, will be the best habitat for endangered species of wild fauna and flora if we classify the various habitat types and create a habitat map. In doing this project, we need to include the estuary of the Han River and the lagoon (brackish water lake) of the East Sea coast. In addition, we must establish long-term plans for conservation and sustainable use and do international scientific research across the DMZ region in collaboration with scientists of South and North Korea and international experts. Mutual cooperation between the two Koreas for investigation and conservation efforts is paramount.

A plant factory is a facility that creates an artificial environment in a controlled space and produces plants systematically through automated facilities. However, automation in the cultivation process is insufficient compared to the internal environment control technology in plant factories. This causes the problem of an increase in operating costs due to the input of a large number of workers. Therefore, this study aims to evaluate economic feasibility by comparing before and after introducing automation in the cultivation process of plant factories. The target plant factory to be analyzed was selected, and the break-even point analysis method was used by comparing the cost required compared to the operating period. As a result, the break-even point was analyzed to be 3.4 years when automation was introduced into six processes for plant cultivation. Therefore, it can be judged that the introduction of automation is excellent in terms of economic feasibility when the target plant factory has been operated for more than 3.4 years. This study is expected to be used as basic data to analyze the economic feasibility of introducing automation in domestic and foreign plant factories.
