By the end of 2017, in a world of 7.6 billion people, there were inequalities in healthcare indices both within and between nations, and this gap continues to increase. Therefore, this study aims to understand the current status of regional inequalities in healthcare indices and to find an action plan to tackle regional health inequality through a geo-economic review in Korea. Since 2008, there was great inequality in life expectancy and healthy life expectancy by region in not only metropolitan cities but also districts in Korea. While the community health statistics from 2008-2017 show a continuous increase of inequality during the last 10 years in most healthcare indices related to noncommunicable diseases (except for some, like smoking), the inequality has doubled in 254 districts. Furthermore, health inequality intensified as the gap between urban (metropolitan cities) and rural regions (counties) for rates of obesity (self-reported), sufficient walking practices, and healthy lifestyle practices increased from twofold to fivefold. However, regionalism and uneven development are natural consequences of the spatial perspective caused by state-lead developmentalism as Korea has fixed the accumulation strategy as its model for growth with the background of export-led industrialization in the 1960s and heavy and chemical industrialization in the 1970s, although the Constitution of the Republic of Korea recognizes the legal value of balanced development within the regions by specifying "the balanced development of the state" or "ensuring the balanced development of all regions." In addition, the danger of a 30% decline or extinction of local government nationwide is expected by 2040 as we face not only a decline in general and ageing populations but also the era of the demographic cliff. Thus, the government should continuously operate the "Special Committee on Regional Balanced Development" with a government-wide effort until 2030 to prevent disparities in the health conditions of local residents, which is the responsibility of the nation in terms of strengthening governance. To address the regional inequalities of rural and urban regions, it is necessary to re-adjust the basic subsidy and cost-sharing rates with local governments of current national subsidies based mainly on population scale, financial independence of local government, or distribution of healthcare resources and healthcare indices (showing high inequalities) overall.

Regarding climate change, the most significant challenge the world faces is achieving the goal of stabilizing the global concentration of greenhouse gases. However, this cannot be accomplished by greenhouse gas reduction efforts of developed countries alone. In this context, a "sectoral approach" has been brought up as a way to overcome the limit of the Kyoto Protocol and induce the participation of developing countries. This paper focuses on the different types of sectoral approaches that have been suggested so far, and their criteria, scope and effectiveness. It therefore explores the potential each approach has as a policy alternative under the post-2012 scheme. On top of that, with the possibility of these sectoral approaches becoming strong future policy alternatives in mind, this paper also analyzes their applicability to the Korean industry. For the steel, petrochemical and oil industries - in which energy efficiency exceeds the world average- a technology-based approach is proposed as an alternative. For the cement, paper and power generation industries - in which energy efficiency is about the same as the global average - a sectoral crediting mechanism or an index-based approach or a sector-wide transnational approach are proposed as alternatives. Lastly, this paper suggests a future research direction for their adoption and implementation.

Recently many companies began to feel the pressures of cost savings due to the global recession, so they have been interested in the Cloud Computing. Cloud Computing is one of using method of IT resources through the network. Users can borrow softwares or hardwares instead of buying them. Many people expect remarkable growth in Cloud Computing industry because of it's effectiveness. But Cloud Computing industry is still at an early stage. Especially, people who in the public sector hesitate to adopt Cloud Computing Services due to security issues and their conservative views. Also, they just have limited understanding, so we need to investigate what they really know and understand. Researches about the Cloud Computing generally focus on technical issues, so we can hardly find researches reference for decision making in considering the services. The study aims to investigate diverse factors for agencies' adoption decisions, such as benefits, costs, and risk in developing the most ideal type of cloud computing service for them, and performs priority analyses by applying ANP (Analytic Network Process). The results identify that features pertaining to the risk properties were considered the most significant factors. According to this research, the usage of private cloud computing services may prove to be appropriate for public environment in Korea. The study will hopefully provide the guideline to many governmental agencies and service providers, and assist the related authorities with cloud computing policy in coming up with the relevant regulations.

In the present study, we collected the information of the 18 major food safety incidents and conducted a delphi survey with 10 experts to analyze the effect of difference between terms used in reporting of the major food safety incidents on risk communication. In the result of the analysis of information from the major food safety incidents, discord of terms used from government, local government, media and consumer groups had a tremendous effect on the socioeconomic losses and caused the expansion of the incidents. The survey with 10 experts showed that there was a high correlation between the difference in ripple effect of reporting terms and the difference in reporting terms. A correlation coefficient was 0.865. Therefore, ripple effect of incidents was significantly affected by reporting terms and we concluded that standardization of term is necessary in reporting of the food safety incidents. These results can be used as a basic material for successful risk communication among the government, enterprises and consumers.

이동코드는 자바 애플릿(applet)이나 스크립트와 같이 원격지에서 실행가능한 코드로서 현재 웹브라우저를 통하여 쉽게 수행 가능하다. 이러한 프로그램은 누구나 작성할 수 있고 브라우저를 수행할 수 있는 어떤 컴퓨터에서도 수행 가능하다. 즉, 자바 애플릿과 같이 운영체제나 하드웨어에 관계없이 어떤 플랫폼에도 동일 코드가 수행될 수 있다. (일반적으로 에이전트도 이동 코드라고 부르지만 여기서는 포함시키지 않는다.) 인터넷에서 어떤 컴퓨터에서도 공통적인 스크립트를 수행할 수 있다는 것은 편리함, 가능성에서 많은 장점을 가지고 있지만 보안 관점에서 보면 이러한 공통의 스크립트를 수행할 수 있는 인터프리터는 매우 위험하다. 또한 이러한 인터프리터가 브라우저의 한 부분이기 때문에 위험은 더욱 증가한다. 이동 코드 인터프리터에서 어떤 버그가 존재할 경우 이것을 이용한 악성 사용자가 프로그램을 특정 컴퓨터에서 수행시켜 접근 권한을 쉽게 얻거나 시스템을 파괴할 수 있다. 일반 사용자들이 주로 사용하는 윈도95 같은 운영체제에서는 이러한 공격을 막을 보호대책이 없고 심지어 UNIX에서도 사용자의 권한을 가지고 이동 코드가 수행되기 때문에 사용자의 파일을 조작하거나 정보가 유출될 수 있다. 또한, 이동코드가 서로 다른 수행환경을 이동할 경우, 악성 이동코드로부터 영향을 받을 수 있는 수행환경의 보호와 악성 호스트 및 수행환경에 의해 이동코드가 파괴되는 경우도 있다. 위와 같은 이동 코드의 위험으로부터 발생할 수 있는 보안문제점들의 실제 피해 사례 및 시스템을 보호하기 위해 사용되어온 몇 가지 기법을 제시하였다.사업을 통하여 경남지역 산업단지에 입주한 기업체의 정보 활용을 극대화하여 지역경제 발전에 기여함과 동시에 국내 지역정보화 시범모델로서 위상을 확립하고자 한다.을 기업의 타인자본비용과 자기자본비용의 조합인 기회자본비용으로 할인함으로써 현재의 기업가치를 구할 수 있기 때문이다. 이처럼 기업이 영업활동이나 투자활동을 통해 현금을 창출하고 소비하는 경향은 해당 비즈니스 모델의 성격을 규정하는 자료도로 이용될 수 있다. 또한 최근 인터넷기업들의 부도가 발생하고 있는데, 기업의 부실원인이 어떤 것이든 사회전체의 생산력의 감소, 실업의 증가, 채권자 및 주주의 부의 감소, 심리적 불안으로 인한 경제활동의 위축, 기업 노하우의 소멸, 대외적 신용도의 하락 등과 같은 사회적·경제적 파급효과는 대단히 크다. 이상과 같은 기업부실의 효과를 고려할 때 부실기업을 미리 예측하는 일종의 조기경보장치를 갖는다는 것은 중요한 일이다. 현금흐름정보를 이용하여 기업의 부실을 예측하면 기업의 부실징후를 파악하는데 그치지 않고 부실의 원인을 파악하고 이에 대한 대응 전략을 수립하며 그 결과를 측정하는데 활용될 수도 있다. 따라서 본 연구에서는 기업의 부도예측 정보 중 현금흐름정보를 통하여 '인터넷기업의 미래 현금흐름측정, 부도예측신호효과, 부실원인파악, 비즈니스 모델의 성격규정 등을 할 수 있는가'를 검증하려고 한다. 협력체계 확립, ${\circled}3$ 전문인력 확보 및 인력구성 조정, 그리고 ${\circled}4$ 방문보건사업의 강화 등이다., 대사(代謝)와 관계(關係)있음을 시사(示唆)해 주

Many companies and organizations are building a mobile office environment using the LTE network, the national disaster network and Air Force LTE network are built for public safety and national defense. However the recent threats on information security have been evolving from information leakage to DDoS attacks to neutralize the service. Especially, the type of device such as Smart phones, smart pad, tablet PC, and the numbers are growing exponentially and As performance of mobile device and speed of line develop rapidly, DDoS attacks in the mobile environment is becoming a threat. So far, universal countermeasure to DDoS attacks has been interception the network and server step, Yet problem regarding DDoS attack traffic on mobile network and expenditure of network resources still remains. Therefore, this paper analyzes the traffic type distributed in the private mobile network such as the National Disaster Network, and Air Force LTE network in order to preemptively detect DDoS attacks on terminal step. However, as direct analysis on traffic distributed in the National Disaster Network, and Air Force LTE network is restricted, transmission traffics in Minecraft and uploading video file upload which exhibit similar traffic information are analyzed in time series, thereby verifing its effectiveness through establishment of DDoS attacks standard in mobile network and application that detects and protects DDoS attacks

Lowering threshold value of construction services is extremely sensitive issue to the small and medium enterprises in construction industry. Because it means opening the construction markets where the small and medium construction companies compete intensely. Nevertheless, it is absent that the analysis on the effect of opening the market lowering threshold value of construction services under Government Procurement Agreements or Free Trade Agreement. This research is to analyze the effects of lowering threshold value of construction service which have been agenda repeatedly in the international agreements such as WTO and FTA. The current threshold value of construction services of Korea under WTO GPA are 5million SDR where the government delivers and 15million SDR where the local government or the public institution deliver. However major parties to an entente such as USA and EU have been demanding to lower threshold value of 15 million SDR where the local government or the public institution deliver to 5million SDR. The analysis figure the effect of this lowering threshold value to be a market reduction by 2trillion Won as '07 fiscal year basis. This market shrinkage will effect to the small and medium construction companies in local considerably.

The increased threat to commercial shipping by Somalia-based pirates has triggered an increased use of PMSC(Private Maritime Security Contractors). The use of PMSC to protect merchant ships against Somali-based piracy threat seems to have been most effective counter-piracy measures. However, there are various legal and practical questions around using PMSC and PCASP(Privately Contracted Armed Security Personnel) on board at sea. This paper aims to study the regulation and its problems of PMSC and PCASP on board to protect merchant ships against Somali-based piracy in the Indian Ocean and Gulf of Aden. In particular, this paper focuses on the legal issues including jurisdictional issues of PCASP on board merchant vessels, use of force by PCASP in self-defense, and authority for using PMSC. Currently, the legal framework relating to use of PMSC and PCASP on board protecting ships from Somali-based piracy is complex, sometimes ambiguous or inconsistent, and currently in a state of flux. Thus, this paper concludes that at this juncture an effort to coordinate this legal framework is necessary, as regards both the interpretation of existing rules related to PCASP on board merchant ships under UNCLOS(United Nations Convention on the Law of the Sea) and the creation of new rules. Also, this paper suggested that there is an urgent need to establish the PMSC-specific laws in Korea.

The ship's chart system was changed from the use of paper chart to the ENC (Electronic Navigational Chart) using ECDIS (Electronic Chart Display and Information System). The introduction of ENC in ships is necessary for ship automation and for the digitalizing of data and integration of information, but unexpected various problems have occurred and are posing a great threat to safe navigation in the transitional period when the new system has been applied to the sea. In this paper, to assess whether ECDIS contributes to the safety of navigation for its intended purposes as new navigation equipment, a usability test of ECDIS was conducted on masters and crew who have used ECDIS on ocean-going vessels. The result was verified with a paired sample T-test, and it was significantly analyzed with the effectiveness of a simplified task; cost efficiency was decreased since ECDIS was used. By analyzing 'MSC.1/Circ.1503 ECDIS - Guidance for good practice', we found that the effects of the maintenance of ECDIS software, operating anomalies identified within ECDIS, differences between raster chart display system (RCDS) and ECDIS, and matters of identification were compounded by the overlapping information on the safety of ships. The anomalies were also grouped according to their characteristics, and we proposed suitable improvements accordingly. The reason for the reduction in efficiency in the usability test was that the problems with ECDIS were intended to be solved only with the careful use of navigational officers who did not have systematic solutions. To solve these problems, the maintenance of software, the improvement of ECDIS anomalies, the reliable ENC issuance including the global oceans, and S-mode development are a priority.
