영국은 1990년대, 특히 신노동당 정부 이후 지속가능발전 또는 탄소규제를 국가 발전의 핵심 전략으로 추진해 왔다. '정부를 녹색화'하고자 하는 이러한 영국 환경정책과 더불어 실제 에너지환경지표의 가시적 성과는 '저탄소 녹색성장'을 추구하고자 하는 우리나라의 정책 입안가 및 연구자들의 주목을 끌었다. 이 논문은 이러한 영국의 탄소규제 전략과 환경정책의 특성을 단순히 정책적 통합화 또는 주류화를 넘어서 새로운 국가발전 전략, 즉 '생태적으로 근대화된' 국가, '생태국가' 또는 '녹색국가' 전략으로 규정하고자 한다. 즉 최근 영국은 탄소규제를 국가 정책의 통합적 원칙으로 설정하는 한편 주로 시장-의존적 신자유주의에 바탕을 두고 국가 전체를 동원하는 녹색국가 전략을 추진하고 있는 것으로 이해된다. 이러한 점에서 이 논문은 영국의 탄소규제 관련 환경정책의 전개과정을 서술한 후, 탄소규제를 녹색국가 발전을 위한 새로운 원칙이며, 실제 중앙정부 부처들과 지자체들을 통합하기 위한 거버넌스 구축의 바탕이지만, 신자유주의에 포섭된 것으로 재평가하고자 한다. 또한 이 논문은 영국의 이러한 녹색국가 전략의 직 간접적 성과라고 할 수 있는 최근 에너지 환경지표의 동향을 분석하고, 경험적 재평가로서 영국의 에너지 수입의존도 증대, 에너지 혼합에서 석탄 비중의 증가, 전력 생산의 민영화, 재생가능에너지 생산의 한계, 그리고 에너지 이용 및 온실가스 배출의 공간적 불평등 등을 지적하고자 한다.

Purpose: This study examined the development and performance of the school health promotion policy guideline that is applicable to Korean school health. Methods: 1. The WHO's guideline was translated into Korean and modified by school health experts 2. A questionnaire was conducted to assess the performance of school health policy on 207 nurses in elementary schools in Seoul and Cheonbuk. Result: The Korean version of the school health promotion policy guidelines were developed including 9 components and 36 checkpoints. Compared to that of WHO, the component 'school nursing teacher' was added and three components were eliminated: 'equitable access to school resources', 'control of helminth', and 'sun protection policy'. The performance degree of first-aid, closure of school in a calamity, and control of HIV/AIDS was very low. The performance degree of a healthy diet, and regular physical examination was quite high. This study was the first that developed the school health promotion policy guideline and examined the performance. Further research is needed to validate the guidelines developed by this study.

Objectives: The purpose of this manuscript was to review Intersectoral Collaboration policies for Tobacco Control. Methods: The author selected the WHO Framework Convention on Tobacco Control and adopted guidelines, and reviewed intersectoral and multisectoral collaboration policy recommendations. Results: There are 11 chapters and 38 articles in the Convention. In the Demand reduction policies included price and non price measures. The author selected a few non price measures for cross sectoral collaboration examples. They are protection from exposure to tobacco emission, education and communication, banning advertising, promotion and sponsorship of tobacco products, and offering treatment to tobacco use cessation. Inter sectoral and multi sectoral approaches could increase effectiveness, and better outcome of the tobacco control policy for implementation of many different articles of FCTC. Conclusions: It is important to give a specific role in structures of different government sectors and infrastructure for intersectoral collaboration. In addition, the role of civil society is very important for implementation of tobacco control policy effectively, and governments have to support the civil society for anti-smoking activities and campaigns.

Purpose: To describe nurses' attitude to smoking cessation interventions and importance of participation in tobacco control policy. Method: The participants were 841 nurses practicing in hospitals of 400 beds or more and 103 members of a professional nurse's academic society. The hospitals were systematically selected to cover the whole country. The questionnaire was adopted from the 'Oncology Nurses' Tobacco Control Survey' and used after translation, Results: Nurses who were older, married, had higher positions, more education, more experience, and who worked in an OPD setting had higher mean score for attitude to the involvement of nurses in smoking cessation interventions. More than 80% of nurses agreed on the importance of nurses' participation and involvement in tobacco control policy. However, only 65.4% of nurses stated that supporting laws to increase cigarette price was important. Conclusion: Clinical nurses' attitudes to smoking cessation interventions were positive and participants supported the importance of participation in tobacco control policies.

IT security companies have been releasing file system filter driver security solutions based on the whitelist, which are being used by several enterprises in the relevant industries. However, in February 2019, a whitelist vulnerability was discovered in Microsoft Edge browser, which allows malicious code to be executed unknown to users. If a hacker had inserted a program that executed malicious code into the whitelist, it would have resulted in considerable damage. File system filter driver security solutions based on the whitelist are discretionary access control (DAC) models. Hence, the whitelist is vulnerable because it only considers the target subject to be accessed, without taking into account the access rights of the file target object. In this study, we propose an industrial device security system for Windows to address this vulnerability, which improves the security of the security policy by determining not only the access rights of the subject but also those of the object through the application of the mandatory access control (MAC) policy in the Windows industrial operating system. The access control method does not base the security policy on the whitelist; instead, by investigating the setting of the security policy not only for the subject but also the object, we propose a method that provides improved stability, compared to the conventional whitelist method.

Robot's throwing control is difficult to accurately calculate because of air resistance and rotational inertia, etc. This complexity can be solved by using machine learning. Reinforcement learning using reward function puts limit on adapting to new environment for robots. Therefore, this paper applied deep reinforcement learning using neural network without reward function. Throwing is evaluated as a success or failure. AI network learns by taking the target position and control policy as input and yielding the evaluation as output. Then, the task is carried out by predicting the success probability according to the target location and control policy and searching the policy with the highest probability. Repeating this task can result in performance improvements as data accumulates. And this model can even predict tasks that were not previously attempted which means it is an universally applicable learning model for any new environment. According to the data results from 520 experiments, this learning model guarantees 75% success rate.

Recently, flash cache is widely adopted as the performance accelerator of legacy storage systems. Unlike other cache media, flash cache should be carefully managed as it has peculiar characteristics such as long write latency and limited P/E cycles. In particular, we make two prominent observations that can be utilized in managing flash cache. First, a serious worn-out problem happens when the working-set of a system is beyond the capacity of flash cache due to excessively frequent cache replacement. Second, more than 50% of data has no hit in flash cache as it is a second level cache. Based on these observations, we propose a cache admission control policy that does not cache data when it is first accessed, and inserts it into the cache only after its second access occurs within a certain time window. This allows the filtering of data disruptive to flash cache in terms of endurance and performance. With this policy, we prolong the lifetime of flash cache 2.3 times without any performance degradations.
