The purpose of this study is to construct a flatfish outlook model that is consistent with the "Fisheries outlook" monthly publication of the fisheries outlook center of the Korea Maritime Institute (KMI). In particular, it was designed as a partial equilibrium model limited to flatfish items, but a model was constructed with a dynamic ecological equation model (DEEM) system, considering biological breeding and shipping times. Due to limited amounts of monthly data, the market equilibrium price was calculated using a recursive model method as the inverse demand. The main research results and implications are as follows. As a result of estimating young fish inventory levels, the coefficient of the young fish inventory in the previous period was estimated to be 0.03, which was not statistically significant. Because there is distinct seasonality, when estimating the breeding outcomes, the elasticity of breeding in the previous period was found to exceed 0.7, and it increased more as the weight of the fish increased, in addition, the shipment coefficient gradually increased as the weight increased, which means that as the fish weight increased, the shipment compared to the breeding volume increased. When estimating shipments, the elasticity of breeding in previous period was estimated to respond elastically as the weight increases. The price flexibility coefficient of the total supply was inelastically estimated to be -0.19. Finally, according to a model predictive power test, the Theil U1 was estimated to be very low for all of the predictors, indicating excellent predictive power.

Currently the oriental medical care services in the health centers is getting popularity because of their unique aspects which western medicine can not cover. This study was conducted to speculate the current status of oriental medical care services in health centers and possibility of how to effectively provide the oriental medical care services(or traditional medical care services) in health centers. For the study, the survey questionnaires were distributed to all 269 health centers and 138(51.3%) of them were collected. Eight of the collected were inadequate for the analysis and 130 of 269 questionnaires were finally chosen for the study. The SPSS/PC WIN 8.0 was used for the statistical analysis. The results are as follows. First, 91 out of 130 sample health centers(70%) are providing oriental medical care services. The results show that the willingness of the directors and the public awareness in community are the most important factors to provide oriental medical care services in health centers. In contrast, the lack of cooperative efforts between western and oriental medical doctors and the lack of government supports are considered as factors that intervene the oriental medical care services in health centers. About 80% of the sample health centers respond that the government supports is needed for oriental medical care services in health centers. Second, it was asked to the directors of 39 health centers which do not provide oriental medical care services regarding their future plan to include the services. About 70% of health centers respond that no plan is available now. They acknowledge that the demand on the services is the most important factor to consider the oriental services as their future medical services. Third, 69.2% of the oriental medical doctors in health centers are public health doctor. 95.6% of the sample health centers have space for the oriental medical care services in their facilities and some health centers provide the services through the private clinics nearby facilities. Finally, the surveyors consider both budgetary constraints and difficulty in recruiting doctors as barriers for the effective oriental medical care services in health centers. Finally, t-test and LSD were employed to find out the difference among several groups. The analysis shows statistically significant difference among groups about their recognition on health care policy, health care system, and effectiveness of oriental medical care services. To be conclude, the study shows the necessity of oriental medical care services in health centers. To do so, the government supports, cooperative efforts between oriental and western medical doctors, and providing job security for doctors should proceed to provide effective oriental medical care services in health centers.

The purpose of this study is to investigate the impact of the Internet channel introduction on the channel composed of a monopoly manufacturer and an independent physical retailer. This study also examines what would be the best strategy for the Independent physical retailer to respond to the new internet channel entry. The game theoretic model consists of a monopolist manufacturer selling its product through a channel system including one independent physical store before the entry of an internet store. The audition of the internet store to this channel system results in a mixed channel comprised of two different types of channels. The new internet store is launched by the manufacturer. The results show that an Internet channel entry has the following impacts on the existing channel members. First, the manufacturer's internet channel introduction mitigates the double marginalization problem of the traditional channel. Second, the manufacturer could enhance Its channel power by introducing its own internet channel while it diminishes that of the incumbent independent physical retailer. Third, manufacturer's adding a new internet store leads to a higher demand. Finally, with its own internet direct channel, the manufacturer has an opportunity to practice price discrimination. The manufacture leaves only those with a strong preference for the physical store to be served by the Independent physical store. The results suggest that the independent physical store's best strategy to the entry of the manufacturer's Internet channel is to focus on the consumers who are highly loyal to the physical store while maintaining a high retail price.

This study is aimed to suggest a direction for the general environment education through analyzing current environment education curriculums and survey of educational needs for students in Korean universities. Since the result of this survey shows that most university students lack experience in environmental education in their secondary education, the basic educational programs as well as advanced educational programs should be included to develop a general environmental education curriculum for university students. So far, general environmental education for university students has not witnessed a clear and distinct object and direction. Since we live in a situation where environmental problems should be considered in every aspect of our society, the general environmental education curriculum for university students shall play a role to solve these problems. Additionally, we need to change the way of environment education from educating and raising the environment professionals to educating and raising people who comprehensively understand economy, society and environment under the sustainable development paradigm. Also the focus of environmental education should swift from natural science to over all perspectives. Recently, the need of interdisciplinary curriculum for the environment education field has been discussed in universities. However, it has not been integrated into the normal curriculum. In this regard, systemic improvement which enables general education curriculum to operate flexibly will be followed. The key to establish an interdisciplinary curriculum is a flexible educational curriculum system which can solve problems arising from departmental curriculums, and promptly respond to the demand of educational and social consumers. Additionally, the result of survey shows that students want diverse educational operations and teaching methods, equipping educational assistance system for these needs will be required.

In 2020, the coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented disruptions to global health systems. The Korea has taken full-fledged actions against this novel infectious disease, swiftly implementing a testing-tracing-treatment strategy. New obligations have therefore been given to the Health Insurance Review and Assessment Service (HIRA) to devote the utmost effort towards tackling this global health crisis. Thanks to the universal national health insurance and state-of-the-art information communications technology (ICT) of the Korea, HIRA has conducted far-reaching countermeasures to detect and treat cases early, prevent the spread of COVID-19, respond quickly to surging demand for the healthcare services, and translate evidence into policy. Three main factors have enabled HIRA to undertake pandemic control preemptively and systematically: nationwide data aggregated from all healthcare providers and patients, pre-existing ICT network systems, and real-time data exchanges. HIRA has maximized the use of data and pre-existing network systems to conduct rapid and responsive measures in a centralized way, both of which have been the most critical tactics and strategies used by the Korean healthcare system. In the face of new obligations, our promise is to strive for a more responsive and resilient health system during this prolonged crisis.

As the uncertainty of technology development and market needs increases due to changes in the global business environment, the interest and demand for R&D activities of individual companies are increasing. To respond to these environmental changes, technology commercialization players are paying great attention to enhancing the qualitative competitiveness of R&D. In particular, R&D companies in the marine and fishery sector face many difficulties compared to other industries. For example, the R&D environment is barren, it is challenging to secure R&D human resources, and it is facing a somewhat more difficult environment compared to other sectors, such as the difficulty in maintaining R&D continuity due to the turnover rate of researchers. In this study, based on the empirical data and patent status of private companies closely related to the R&D technology status, big data analysis, and simulation analysis methods were used to identify the relative position of individual companies' R&D capabilities and industrial perspectives. In this study, based on industrial evidence and patent applications closely related to the R&D technology status, the R&D capabilities of individual companies were evaluated using extensive data analysis and simulation analysis methods, and a statistical test was performed to analyze if there were differences in capabilities from an industrial point of view. At this time, the industries to be analyzed were based on all sectors, the maritime industry, the fisheries industry, and the maritime industry integration sector. In conclusion, it was analyzed that there was a certain level of difference in the R&D capabilities of individual companies in each industry sector, Therefore when developing a future R&D capability system, it was confirmed that it was necessary to separate the population for each industry and establish a strategy.
