The emission of air pollutants in China has increased rapidly as its economy expanded over the last decades. The Chinese government has recently acknowledged the seriousness of the resulting air pollution and is trying to improve air quality in many ways. Here, we review the air quality control and management policies in China, one of our closest neighbors, because these policies may also influence the air quality in Korea. This study examined the recent policies on $PM_{2.5}$ reduction and analyzed the variation in air quality and air pollutant emissions in China. The ambient air quality and emission standards in China have been strengthened, based on China's Air Pollution Prevention and Control Action Plan of 2013. As a result, the annual mean concentration of $PM_{2.5}$ in 2015 in 74 large Chinese cities declined by 23.6% compared with 2013 values. Coal consumption in China also has been reduced by more than 10% per year since 2013. Furthermore, the laws controlling atmospheric emissions were revised again in 2016, and an air pollution forecasting and warning system was implemented to help manage air pollution problems. At present, the Chinese government is trying to evaluate its policies on $PM_{2.5}$ and find a new paradigm to mitigate ongoing $PM_{2.5}$ pollution. In this context, a joint study between Korea and China has been initiated to investigate the characteristics and sources of ambient $PM_{2.5}$ and to identify factors contributing to the high $PM_{2.5}$ concentrations in northeast China. We expect that this academic collaboration will benefit both countries in their search for new policies for $PM_{2.5}$ reduction.

폐기물 매립지에 바이오리액터 매립공법을 적용하는 것이 폐기물의 생물학적 압축 촉진에 미치는 영향을 분석하기 위하여 실내침하실험을 수행하고, 그 결과 구한 2차 압축지수(C_α)를 국외연구결과와 비교하였다. 실내침하실험의 2차 압축지수들을 분석한 결과 침출수에 음폐수를 혼합하여 재순환하는 방법은 음폐수 내 유기물질이 추가적인 생물학적 압축을 유발하며 침출수 재순환과 위생매립공법보다 폐기물 침하를 각 2배, 2.81배 가속화할 수 있는 것으로 나타났다. 본 연구에서 사용한 폐기물의 2차 압축지수는 국외연구 폐기물의 2차 압축지수보다 작았는데 그 이유는 음식물 쓰레기를 감소시키기 위한 국내 폐기물 정책에 따라 폐기물 내 유기물 함량이 감소하였기 때문이다. 생분해성 폐기물 함량과 2차 압축지수의 관계를 분석한 결과 폐기물의 2차 압축지수는 생분해성 폐기물 함량에 민감하며 생분해성 폐기물 함량이 증가할수록 커지는 것으로 나타났다.

본 연구는 IoT 분야의 다양한 정부정책을 파악하고, 이들 간 상대적 중요성을 분석하고자 하였다. 이를 위해 전문가를 대상으로 Analytic Hierarchy Process(AHP)분석방법을 활용하였다. 그 결과, 첫째, IoT 관련 정책범위가 광범위함에도 불구하고, 학계, 산업계 등의 정책 전문가가 매우 제한적이었고, 둘째, 만족도관점에서 해외진출정책, R&D지원 정책, 벤처지원정책, 인력양성정책, 규제정책의 순이었으나 전반적인 만족도 수준은 낮았으며, 셋째, 중요성 관점에서 벤처지원이 가장 높았으며, 그 다음으로 R&D지원, 인력양성, 규제정립, 해외진출의 순으로 높았다. 종합하면 연구활동 지원, 해외시장 개척지원, 벤처제품우선구매, 산학협동 대학교육 강화 등의 선도자적 정부역할에 높은 중요성을 부여하고 있었던 반면에 조정자적 역할에 대한 중요도 인식은 상대적으로 낮았다. 그러나 전문가집단도 정부가 중요한 프로젝트에서는 기본적으로 시범사업이나 실태조사 등을 수행해 와서, 이의 중요성에도 불구하고 제대로 인식하지 못하였을 수 있다.

Purpose: To evaluate the effectiveness of new management policies on the incidence of invasive Candida infections Methods: This observational study involved a retrospective analysis of the patients' medical records. In total, 99 very low birth weight infants, who were admitted to the neonatal intensive care unit at Ajou University Hospital from January 2010 to December 2011, were enrolled for the study. Period I, defined as the period before the revision of management policies, comprised 57 infants; whereas, period II, defined as the period after the implementation of new management policies, comprised 42 infants. The new management policies entailed a reduction in antibiotic and histamine type 2 receptor blocker (H2 blocker) use, duration of central venous catheterization, and duration of endotracheal intubation. Results: There was a significant overall decrease in the use of antibiotics including 3rd generation cephalosporin and H2 blockers (P<0.05), and a significantly lower incidence of invasive Candida infections in period II as compared to period I (0/42 vs. 6/57, respectively; P=0.037). Comparison between infants with invasive Candida infections (n=6) and those without (n=93) showed that gestational age (odds ratio [OR], 0.909; 95% confidence interval [CI], 0.829 to 0.996; P=0.042) and the duration of 3rd generation cephalosporin use (OR, 1.093; 95% CI, 1.009 to 1.183; P=0.029) were statistically significant risk factors. Conclusion: The new management policies effectively decreased overall use of antibiotics, especially 3rd generation cephalosporin, and H2 blockers, which led to a significantly lower incidence of invasive Candida infections.

Biofuls are considered as an option to reduce greenhouse gases emission, increase energy supply diversity and security of supply, as well as an opportunity for job creation and rural development. First of all, biofuls technologies have been promoted as a means for reducing the carbon intensity of the transport sector. Hence, in the last decade biofuels production has been driven by governmental policies. The key instruments widely adopted to foster production and increase consumption have been mandatory blending targets, tax exemptions and sibsidies. As one of the most powerful instruments, biofuel mandates require fuel producers to produce a pre-defined amount (or share) of biofuels and blend them with petroleum fuel. National biofuels mandates are in place 35 countries and partially in place in 6 countries. In this study, we reviewed status of global biofuels policies to reduce greenhouse gases in the European Union, United States and other countires worldwide. Especially, we discussed representative biofuels mandates policies same as Renewable Fuel Standard (RFS, US), Renewable Transport Fules Obligation (RTFO, UK) in transport sector.

Recently junior colleges in Korea have been working to meet changes in industrial and educational surroundings by establishing new departments, integrating and abolishing existing ones, or adjusting departmental quotas. These endeavors need to be based on an analysis of industrial policies, both national and international, and of the industrial trend of the region in which the particular college is located. They also need to take into consideration change in educational policies and the direction of the college's specialization. This study aims to provide some foundation materials for these endeavors. As a result, it has considered changes in industrial and educational surroundings and analyzed the whole spectrum of departments existing at Korean junior colleges, with a focus on business-related ones. In the course it has taken a look at the division system, presently a hot issue regarding the restructuring of the colleges. To summarize, each college offers departments, having taken into consideration its regional, industrial, and educational environments. The result of this study may be utilized by colleges when they establish new departments, integrate and abolish existing ones, and adjust departmental quotas. When they utilize the result, the colleges are advised to consider changes in the structure of industries and manpower, those in educational policies, and the direction of their specialization.

This study aimed to systematically adjust rural area development projects that have been carried out by a variety of government departments for activation of rural areas and overcome inefficient problems caused by the policies and projects promoted separately. As its alternative, this study aimed to explore efficient improvement scheme of rural villages associated with various projects. Major agriculture/rural policies and projects that have been promoted were classified by the target space of the policies and projects as Environment space, living space, and production space. Each space was categorized into five sub-items without duplication. By assessment results of rural area improvement level and preference by Analytic Hierarchy Process(AHP) method, maintenance of rural areas was classified into four types. And outer space structure was analyzed by using Space Syntax Method(SSM). Based on the analysis result above, facilities for improvement of rural villages were placed around representative facilities. Facility allocation was based on selection and concentration in terms of facility maintenance and on type attributes in terms of spatial aspects. And finally, alternatives schemes for setting up the basic direction of improvement of rural villages are local area characteristics and environmentally conscious business plan.

This paper reviews the achievements of the infrastructure investment policies since around 1990 and identifies policy area in which further efforts should be made. Traditional definition of social overhead capital has implied that the government should be the main, if not sole, supplier of the service. However, many sectors or sub-sectors of infrastructure investment and service allow room for private sector involvement. Expanding the role of the private sector will supplement the resources of the public sector, but more importantly, introduce competition in infrastructure provision. Competition will enhance the efficiency even a particular service remains in the hand public supplier. Private sector involvement, however, raises special problems in Koran context. They are the concentration of the Capital region and regional imbalance; excessive economic powers of large business conglomerator, so-called land problems. We examine each problems in detail and suggests possible solutions.

Passwords are used in many ways to protect data, systems, and networks. Passwords are also used to protect files and other stored information. In addition, passwords are often used in less visible ways for authentication. In this article, We provides recommendations for password management, which is the process of defining, implementing, and maintaining password policies throughout an enterprise. Effective password management reduces the risk of compromise of password-based authentication systems. Organizations need to protect the confidentiality, integrity, and availability of passwords so that all authorized users - and no unauthorized users - can use passwords successfully as needed. Integrity and availability should be ensured by typical data security controls, such as using access control lists to prevent attackers from overwriting passwords and having secured backups of password files. Ensuring the confidentiality of passwords is considerably more challenging and involves a number of security controls along with decisions involving the characteristics of the passwords themselves.
