This paper analyzes the profitability of the Private Finance Initiative(PFI) ports and proposes the application plans of the R-project(Rehabilitate project) for old ports to attract and activate private investment in the port industry. The R-project of old ports can reduce the government's financial budget and provide improved facilities for users more quickly than the public sector comparator. Before suggesting the R-project for old ports, the profitability of the currently operating 11 companies of the PFI ports are analyzed using the four ratios of profitability, and the results show that all the companies indicate low profitability, except for the top three companies. To apply the R-project, the three types of R-project ports are categorized as maintaining the function of the port, changing the function of the port, and mixing the function of the port. Additionally, three obstacles and improvement measures are suggested; attracting private business, legal issues, and administrative procedures. This study is conducive to the policy making for the port renewal and the activating PFI for the port industry.

The purpose of this study was to identify the factors affecting the use of superior general hospitals on public holidays by using the medical use model (Dutton's medical use model) with the medical panel data. The study found that 34.2% of superior general hospital emergency rooms were used on public holidays and the factors which made statistically significant influences on the use of superior general hospital emergency rooms on public holidays were whether patients were operated or emergency care and inspection etc. Also, there was a difference depending on whether the type of establishment of the medical insititution is national or private. In other words, patients who received emergency care and examinations were found to make more frequent visit to hospital emergency room on pubic holiday, compared to patients who underwent surgery and those who visited emergency rooms in the private superior general hospital did so, compared to those who visited emergency room in the national general hospital(OR, 4.4, 3.386, respectively). Therefore, it is necessary to consider the introduction of integrated care of health and social care medical service that focuses on primary care in Denmark, which focuses on patients, and pre-The Canadian Triage and Acuity Scale(pre-CTAS) in the UK.

Cloud computing is internet-based computing technology. This is a form for exchanging service focused on the Internet. Because Cost is saved and use is easy there's a tendency that many companies are using. Cloud is in the form of a public cloud and private cloud and hybrid cloud. The service model is SaaS, PaaS, IaaS. Cloud computing use is simple but it has a security vulnerability. In particular, there is a vulnerability in virtualization and centralized information. In order to overcome this new security technology is to be developed. In particular, network security technology and authentication technology should be developed. Another way to overcome security responsibilities must be clearly and policies should be unified.

In order to set the simple criteria to distinguish being or not facilities of Consultation about Energy Use Plan, data analysis and case analysis were carried out. This paper proposes that building, one of the facilities, is being object of the Consultation about Energy Use Plan when in the public project, its gross area is more than 75,000 $m^2$ or main transformer capacity is more than 9,000 kVA and when in the private project, its gross area is more than 100,000 $m^2$ or main transformer capacity is more than 11,500 kVA. Also shows that factory, another of the facilities, is being object when in the private project, its main transformer capacity is more than 6,000 kVA or boiler capacity is more than 24 ton/h and when in the public project, its main transformer capacity is more than 3,000 kVA or boiler capacity is more than 12 ton/h.

Objectives: The purpose of this study is to find out differences in oral health status, defined as their oral health and oral health quality of life among the elderly depending on their income and education levels. Methods: This study used 922 senior citizens over 65 from the data (2015) of the 6th National Health and Nutrition Survey (NHNS). The regression analysis was adopted to identify factors affecting their oral health status which has effect on their oral health quality of life. The statistical package SPSS 21.0 was employed. Frequency analysis, chi-squared analysis and regression analysis were used, and the significance level or Cronbach's alpha value was 0.05. Results: Depending on income levels, there were differences in their oral health status as to whether they use oral hygiene products, take dental examinations, join private health-insurances, and delay dental treatments or not. And educational levels also made significant differences in their oral health status as to whether they smoke, drink alcohol, how many times they brush teeth a day, whether they use oral hygiene products, take dental treatments, and join private health-insurances. Regression analysis on the relationship between their oral health status and the oral health quality of life showed that there were significant differences depending on whether they take dental treatments, delay dental medical treatments, smoke, take oral examinations, how many times they brush teeth a day, and whether they use oral hygiene products, or join private health-insurances. Conclusions: The study shows that a comprehensive plan is needed to raise attention on proper oral health-care and ultimately to improve the quality of life by considering the daily number of tooth brushing, oral hygiene product use, regular dental treatments, and other medical uses.

With the recent development of ICT, information exchange through data communication network is increasing. Cryptography is widely used as the base technology to protect it. The initial cryptography technology was developed for military use and authorized only by the nation in the past. However, nowadays, much of the authority was unwillingly transferred to the private due to the pervasive use of ICT. As a result, there have been conflicts between the private demand to use cryptography and the nation's authority. In this paper, we survey the conflicts between nations and the private in the process of formulating the cryptography policy. Morever, we investigate the reality of the cryptography policy in Korea. Our investigations are expected to help the government apply cryptographic control policy in a balanced manner and plan development of cryptography industries. Lastly, we propose a need to establish a cryptanalysis organization and to legislate a legal sanction against fraudulent use of cryptography.
