Because of the recent development of information and communication technology, companies are exposed to various media such as blogs, social media, and YouTube. In particular, exposed news affects the company's reputation. So, while positive news can improve corporate value, negative news can lead to financial losses for the company. In this study, we redefine corporate reputation as social responsibility, vision and leadership, financial performance, products and services through existing literature, and conducted an AHP survey with a total of four components to calculate the weight of each factor. As a result of the calculation, the proportion of financial performance was the highest at 0.41, and products and services, vision and leadership, and social responsibility were the lowest. In addition, in order to measure the reputation of a company, it is classified as a component that defines online news using the LDA technique. In addition, through sentiment analysis, an index for each corporate reputation factor was derived, and the reputation index was calculated by combining it with the AHP analysis result, and Spearman ranking correlation analysis was performed to secure the validity of the research results. Therefore, the significance of this study is that the definition and importance of the constituent factors can contribute to the future planning and development direction of the company, and also contribute to the derivation of the corporate reputation index. This study is significant in that a new analysis methodology that applied AHP analysis results to sentiment analysis was suggested.

This study selected indicators that can represent the characteristics of general hospitals, including local medical centers and Red Cross hospitals, which are representative public health institutions, and analyzed clusters. And we present to benchmark in each cluster. According to the analysis, 276 general hospitals were classified into 13 clusters, and local medical centers and Red Cross hospitals were classified into clusters between 1 and 7 of the total 13 clusters because of their small size. Local medical centers and Red Cross hospitals, selected as excellent hospitals in each cluster, showed significant differences in management performance despite similar regional environment and medical performance, and among them, surgical consultation and internal medical care rates, inpatient and outpatient rates. In order for local medical centers and Red Cross hospitals to play their role as secondary acute hospitals in the region, inpatient care services and surgical functions must be activated.

In the current business environment where dependence on IT has increased rapidly, the risk from disasters or cyber-attacks is also increasing. Business continuity, the ability to continue to provide service in the event of a business disruption caused by a disaster, is essential. In other words, you need to have a plan in place to keep your core business functions uninterrupted with rapid recovery within a predetermined Recovery Time Objective (RTO) and Recovery Point Objective (RPO) time frame. In this paper, we propose a disaster recovery system construction method that can minimize RTO and RPO to ensure business continuity. The system configuration adopts Tier 7 disaster recovery model, synchronous storage replication, hot disaster recovery site, and operation management automation solution. This ensures continuity of core business with virtually no data loss and minimal RTO and RPO.

As the trend towards expanding the functions of modern governments continues, there are also problems such as misconduct and waste that arise as government activities and operations increase. To solve these issues, countries are establishing and developing internal control mechanisms. In this process, the U.S. Inspector General system has been operating for over 40 years with the aim of balancing and overseeing the government and the legislature. Accordingly, this study analyzed in detail the development process of the inspector system, one of the internal control systems promoted by U.S. government agencies, the formation of an inspector community, and the deployment, cooperation, and supervision of inspectors. As a result, the internal control system of domestic government agencies also needs to continue research so that the government and parliament can maintain close relations and introduce the inspector system according to the domestic situation.

Humanities are as crucial as the technology itself in the intelligent information society. Human-centered convergence information technology (IT), which reflects emotional and human nature, can be considered a unique technology with an optimistic outlook in the unpredictable future. Based on this research background, this paper proposed an education model that can improve the IT humanities capabilities of various learners, including elementary and secondary students, prospective teachers, incumbent teachers, school managers, and the general public, through analysis of previous studies on convergence education models. Furthermore, the practical aspects of the proposed model were closely examined so that the proposed education model could be stably incorporated and utilized in the educational field. There are seven strategies for implementing the education model proposed in this paper, including research on textbooks, teaching and learning materials, activation of research results, maker space creation, global joint research, online education operation, developing living lab governance, and diversification of self-sustaining platforms for sustainable and practical education. In the future, validity verification through expert Delphi is required as a follow-up study.

This paper reports the results of the eruption of a volcano on Jeju Island at a certain rate, and the tumulus formed after the eruption and the basalt that erupted from the middle of Mt. Halla washed up to the sea. We analyzed the speed when basalt underground magma breaks through the neutral zone on the ground with an absolute temperature of about 1000K and explodes at an absolute temperature of 1200K at an altitude of 1950m. The density of combustion gas becomes smaller than the surrounding air due to the plume volcanic eruption, which is the heat flow of the flame column due to buoyancy, and buoyancy is generated and an updraft is formed. Flame pillars are classified as continuous, intermittent, and buoyant flame zones. As the speed of the flame pillar of Mt. Halla (1950m) falls from the highest point it has risen, potential energy is converted into kinetic energy and is caused by the flow of fluid, solving these two equations equal, the volcanic eruption velocity is 87.5 m/s. At this time, the density of magma is inversely proportional to the temperature. Geomunoreum (456m) had an explosion speed of 42.6m/s.

This research identified the normal structures of separated families, "wild-geese families"(husbands living in Korea apart from their wives and children who are studying abroad) as we called, in Korea. In particular, this study conducted in-depth interview, using qualitative research method, with 7 wild-geese fathers (fathers who are in order to understand their experiences of separated families. The research findings classified the wild-geese father's experiences into three phases which as "decision-making," "initial," and "maintenance." These phases can be described by five higher factors. First of all, in the phase of decision-making "internal or external needs of children studying abroad at early age" was found to be a crucial factor. Liberation and deficiency as results of separation" mainly described the initial phase. In the phase of maintenance, families experience "exhausted solitary lives," "filling up the families' empty space," and "double jeopardy-worry about both reunifying the family or separating the family, as the longer they are separated."
