This study aims to establish the direction of development of Korean cinematography technology in the era of the 4th Industrial Revolution and present future development plan. First, in order to diagnose the current status, supporting policies of various countries and film technology research trends were analyzed. Each country is expanding the support for film technology including tax credits. Through the analysis of patents and research papers, recent issues have shown that Virtual Reality, HMD, Artificial Intelligence, and Big Data are applied to film technology. Next, the survey results of Korean film technology level for filmmakers were 70% for production, 47.5% for distribution, and 60.3% for screening comparing to the level of the leading country. The gap was caused by the lack of funds for research and development and insufficient government support policies. In addition, interviews with film makers revealed the need to support filmmaking that combines technologies such as localized film technology, artificial intelligence, and deep learning. Finally, it is suggested that technology sharing platform should be developed in the future through the discussions of technology, science and academic experts', and technology development should be carried out in the field. As a result, film technology R&D should be promoted in order to develop technologies specific to movies. Advanced technology foundation for the growth of film technology should be developed to systematically equip the infrastructures such as education and human resources. In addition, technology development that links standardization should be carried out. In this study, we propose the development of Korean film technology to prepare for the 4th Industrial Revolution, and it is expected that the 2022 film technology power nation will be realized.

우리나라 여러 항만들에서 활용중인 항만인센티브제도는 경쟁항만과의 가격경쟁력을 높이는 마케팅 도구로 활용되고 있다. 그러나 각 항만은 보다 정밀한 제도의 설계보다는 경쟁항만의 제도에 대한 즉각적이며 단편적인 모방대응전략을 주로 사용하고 있다. 또한 고객 화물 집단별예산도 이론적 검증 없이 배분되었기 때문에 제도의 효과에 대한 정밀한 분석과 제도의 재설계가 요구되고 있다. 본 연구는 선형계획모형으로 항만인센티브제도를 모형화하고, 광양항을 대상으로 사례분석 하였다. 광양항에 대한 분석결과 기존의 정성적인 방식의 인센티브제도 설계만으로는 이론적으로 미흡한 것으로 분석되었으며, 각 유형 마다 인센티브의 효과 유무 또는 과부족 여부도 확인되었다. 인센티브제도의 전체 예산중 마일리지 예산은 최소화하고 기존화물 집단예산에 61.77%, 그리고 신규(증가)화물 집단예산에 38.23%씩 배분하는 것이 더욱 합리적인 것으로 나타났다. 추후연구에서는 본 연구과정에서 제기된 정확한 모형 구축에 필요한 충분한 기초자료에 대한 접근과 인센티브 제도를 더욱 정확하게 파악할 수 있는 제약조건 등이 대한 보완되어야만 할 것이다.

In this study, a total of 350 households contained 700 individuals in Iganzo village were surveyed to study their literate and poverty levels and their impacts to conservation of the Mbeya Range Forest Reserve. The study included 350 women and 350 men. The majority of respondents were between the ages of 31-40 years old (53%), while the rest were between 41-50 years old (25%) and 21-30 years old (22%). The total income per day per household was calculated and averaged to 4,570 Tanzanian shillings that is equal to about 3 U.S. dollars. The average number of members per household was seven. It was reported that, there is a tremendous decrease in biodiversity composition of the reserve mainly due to poverty (80%) and ignorance (76%) of the people on the importance of the reserve. Other causes for this decrease were reported to be grazing of livestock in the reserve (23%), poor farming systems (68%), which resulted in soil erosion, encroachment (64%) through expansion of farms towards the reserve boundary and charcoal burning (34%). Respondents from Mbeya Urban Water Supply Authority and District Forest Office mentioned lack of funds (49%) and lack of experts (56%) as challenges that face the conservation of the reserve. It was revealed that 25% of respondents had never gone to school, 53% had primary level of education as their highest level of education, 20% had secondary education and 2% had first degree. The null hypothesis that poverty and illiteracy have a positive correlation to forest degradation was accepted based on these findings at a probability of p>0.85. Thus, it was concluded that poverty and illiteracy among Iganzo village residents are the main causes for the degradation of biodiversity in Mbeya Range Forest Reserve.

Uihagipmun was a medical book published by Leecheon during the Ming Dynasty of China in the 16th century and was introduced to Korea during the mid-Joseon Period. This text greatly influenced the establishment of the Donguibogam, an important work in Korean medicine. This study confirms that many medical professionals of the Joseon Dynasty loved the Uihagipmun and that the Uihagipmun was very important during the Joseon Dynasty. Since then, the status of the Uihagipmun in Korean medicine continued to be emphasized by Korean medicine doctors throughout the Japanese colonial era. The translation of the Uihagipmun began in the 1970s as part of the classical Korean medicine translation project under the leadership of the Korean medicine group "Hanbanguiuhoe". However, due to a lack of funds, the translation was delayed and the first edition was published on October 10, 1974. Writings of those who led the translation at that time show that the translation of the Uihagipmun thought that the exact translation of the Uihagipmun in Korean medicine could lead to the scientific and modernization of Korean medicine. Therefore, Gugyeok pyeonjuuihagipmun should not be regarded as a mere translation, but as a medical book of important value in Korean medical history.

The relevance of the study implies the need to explain the main determinants of environmental policy, allowing countries to converge on a common working basis. The purpose of the research is to explore ways in which the environmental aspects of EU regions and territories can be shaped to apply to domestic environmental policy. A total of 997 representatives from the Ukrainian UTCs, who are involved in local environmental policy, participated in the survey. Results of the research. A hierarchy of regional environmental policy objectives has been identified. Three key principles of eco-policy development have been distinguished. The means of the innovative approach strategy implementation have been outlined (formation of the regional market of environmental services; organization of interaction between environmental agencies and market structures; establishment of environmental funds which finance environmental activities; implementation of the "collateral return" system; formation of a system of benefits and loans to enterprises that successfully implement the environmental policy). The means of the prognostic approach implementation strategy to the development of the region's environmental policy have been determined (the use of an orderly and successful long-term strategy of economic development of the region; obligatory consideration in the mechanisms strategy aimed at improvement of environmental management system of the region, interbranch impact of the projects implemented on the region's ecological situation; taking into consideration the economic and geographical peculiarities of the region, the necessary infrastructure, issues of the territorial location of the large enterprises in the region and their impact on the environment). The means of the traditional approach strategy implementation have been outlined (activity programs focused on solution of specific problems, rather than on the implementation of measures for environmental restoration and enhancement; nature conservation problems have interbranch, interdepartmental character due to unity of the region's ecosystem; tracking complexity of changing conditions (water basins, woodlands, air-mass transport), regional boundaries generally do not coincide with natural ecosystems boundaries). The practical significance of the study lies in providing recommendations for the implementation of certain aspects of Ukrainian UTC's environmental policy.

Fintech, which stands for financial technology, is growing fast globally since the economic crisis hit the United States in 2008. Fintech companies are striving to secure a competitive advantage over existing financial services by providing efficient financial services utilizing the latest technologies. Fintech companies can be classified into several areas according to their business solutions. Among the Fintech sector, peer-to-peer (P2P) lending companies are leading the domestic Fintech industry. P2P lending is a method of lending funds directly to individuals or businesses without an official financial institution participating as an intermediary in the transaction. The rapid growth of P2P lending companies has now reached a level that threatens secondary financial markets. However, as the growth rate increases, so does the potential risk factor. In addition to government laws to protect and regulate P2P lending, further measures to reduce the risk of P2P lending accidents have yet to keep up with the pace of market growth. Since most P2P lenders do not implement their own credit rating system, they rely on personal credit scores provided by credit rating agencies such as the NICE credit information service in Korea. However, it is hard for P2P lending companies to figure out the intentional loan default of the borrower since most borrowers' credit scores are not excellent. This study analyzed the voices of telephone conversation between the loan consultant and the borrower in order to verify if it is applicable to determine the personal credit score. Experimental results show that the change in pitch frequency and change in voice pitch frequency can be reliably identified, and this difference can be used to predict the loan defaults or use it to determine the underlying default risk. It has also been shown that parameters extracted from sample voice data can be used as a determinant for classifying the level of personal credit ratings.

It is generally known that a wastewater treatment plant (WWTP) consumes immense energy even if it can produce energy. With an aim to increase the energy independence rate of WWTP from 3.5% in 2010 to 50% in 2030, the Korean government has invested enormous research funds. In this study, cost-effective operating alternatives were investigated by analyzing the energy efficiency and economic feasibility for biogas and power generation using new and renewable energy. Based on the US EPA Energy Conservation Measures and Korea ESCO projects, energy production and independence rate were also analyzed. The main energy consumption equipment in WWTP is the blower for aeration, discharge pump for effluent, and pump for influent. Considering the processes of WWTP, the specific energy consumption rate of the process using media and MBR was the lowest (0.549 kWh/㎥) and the highest (1.427 kWh/㎥), respectively. Energy-saving by enhancing anaerobic digester efficiency was turned out to be efficient when in conjunction with stable wastewater treatment. The result of economic analysis (B/C ratio) was 2.5 for digestive gas power generation, 0.86 for small hydropower, 0.49 for solar energy, and 0.15 for wind energy, respectively. Furthermore, it was observed that the energy independence rate could be enhanced by installing energy production facilities such as solar and small hydropower and reducing energy consumption via the replacement of high-efficiency operating.
