Cloud HSM와 edge-DRM Proxy를 활용한 안전한 원격근무 환경 강화 연구

김현우,이준혁,박원형,Kim, Hyunwoo,Lee, Junhyeok,Park, Wonhyung 한국융합보안학회 2021 융합보안 논문지 Vol.21 No.3

현재 코로나-19 팬데믹 현상으로 인해 기업이나 기관에서는 원격근무를 제공하는 상황에서 안전한 근무환경을 구축하기 위해 논리적 망 분리 기술 중 하나인 가상화 데스크톱 기술을 도입하고 있다. 가상화 데스크톱 기술을 도입함에 따라 기업이나 기관에서는 망분리 환경을 보다 안전하고 효과적으로 운영할 수 있게 되었으며, 업무망에 신속하고 안전하게 접근해 업무 효율성과 생산성을 높일 수 있게 되었다. 그러나 가상화 데스크톱 기술을 도입함에 있어, 높은 사양의 서버와 스토리지, 라이선스의 비용적인 문제가 있으며, 운용 및 관리적인 측면에서의 보완이 필요한 실정이다. 이에 대응하기 위한 방안으로 기업이나 기관에서는 클라우드 컴퓨팅 기반의 기술인 가상 데스크톱 서비스(DaaS, Desktop as a Service)로 전환하는 추세이다. 하지만 클라우드 컴퓨팅 기반의 기술인 가상 데스크톱 서비스에서 공동책임모델은 사용자 접근 통제와 데이터 보안은 사용자에게 책임이 있다. 이에 본 논문에서는 가상 데스크톱 서비스 환경에서 공동책임 모델을 근거로, 사용자 접근 통제와 데이터 보안에 대한 개선 방안으로 클라우드 기반 하드웨어 보안 모듈(CloudHSM)과 edge-DRM Proxy를 제안한다. Due to the current COVID-19 pandemic, companies and institutions are introducing virtual desktop technology, one of the logical network separation technologies, to establish a safe working environment in a situation where remote work is provided. With the introduction of virtual desktop technology, companies and institutions can operate the network separation environment more safely and effectively, and can access the business network quickly and safely to increase work efficiency and productivity. However, when introducing virtual desktop technology, there is a cost problem of high-spec server, storage, and license, and it is necessary to supplement in terms of operation and management. As a countermeasure to this, companies and institutions are shifting to cloud computing-based technology, virtual desktop service (DaaS, Desktop as a Service). However, in the virtual desktop service, which is a cloud computing-based technology, the shared responsibility model is responsible for user access control and data security. In this paper, based on the shared responsibility model in the virtual desktop service environment, we propose a cloud-based hardware security module (Cloud HSM) and edge-DRM proxy as an improvement method for user access control and data security.

박은식의 국교론을 통해 본 대순사상의 민족주의적 특징 : 천지공사와 지상선인에서 나타난 개인의 주체성을 중심으로

김현우 대진대학교 대순사상학술원 2014 대순사상논총 Vol.22 No.-

There are many modern elements in religions appeared in the early Korean modern era. From the nationalism perspective, most religions had tendencies toward anti-feudalism and anti-foreign power. Pak Eun Sik(朴殷植) emphasized the importance to explain those religions as the National Religion in his writing ≪Korea Painful History(韓國痛史)≫. That is, he realized those as one of Korean spirits or souls keeping Korean identities like the Jew's Judaism or the Turk's Islam. In the paper, I try to analyze religions on Kang Jeung San(姜甑山) with Daesoonjinri-hoe as the central figure from Pak's perspective. In the early Korean modern era when Kang went his own the Savior way, Korea and its society got into uncontrollable confusion because of strong demands both of a feudal-state breaking and against pillaging foreign-power especially Japan. For all countries of the world, it is difficult to change from a feudal state into the modern nation state to keep existing society order. Because the reformation under old social systems means the incomplete reformation. So in this era new religions showed the neglected class of people the vision of new society. Meanwhile Korean society try to become a modern state, and now became a recognized modern state in international society. But it is still insufficient to debate on groups and their roles for Korea modernity in that time especially new religions. Since Korea independence, new religions including Daesoonjinrihoe have not receive good reviews because of a certain religion group expansion and the government's regulation and control toward new religions. Till today, I think, Independence Movement as well as reform of modern awareness have not relatively receive reasonable reviews. So I hope to serve as a momentum that in early Korea modern era new religions receive reasonable and positive reviews.

육상 스포츠 스타의 이미지와 스포츠 자신감 간의 관계분석

김현우,오아람 한국스포츠학회 2017 한국스포츠학회지 Vol.15 No.3

Objectives: The objective of this study was to develop models for predicting obstructive sleep apnea (OSA) based on easily obtainable clinical information of patients using various machine learning techniques. Methods: We used a data set that included the records of 1,368 patients, in which 1,074 patients were male (78.5 %), and 294 patients were female (21.5 %). We randomly divided the data into a training set (1,000) and test set (368). Five machine learning methods, i.e., support vector machine model, lasso logit model, naïve bayes, discriminant analysis, and K-nearest neighbor (KNN), with a 10-cross fold technique were used with the proposed model to predict OSA. We evaluated the accuracy, sensitivity, specificity, and precision of each model for three thresholds [Apnea-Hypopnea Index (AHI)≥5, AHI≥15, and AHI≥30]. Results: Among the machine learning techniques, KNN showed the best results compared to the other techniques. The accuracy, sensitivity, specificity, and precision of OSA prediction were 87.0%, 91.0%, 74.4%, and 91.9%, respectively, based on AHI≥5. When the threshold of OSA was AHI≥15 or AHI≥30, KNN provided lower accuracy (79.6% each) and precision (79.0% and 68.7%), which were still higher than those of the other techniques. Conclusions: The model derived from the KNN technique exhibited the best performance based on its highest level of accuracy. We demonstrate that this model is a useful tool for predicting OSA.

We have deposited ZnO thin lms on Si(100) substrates at low temperatures ranging from 25to 300 C by using the metalorganic chemical vapor deposition (MOCVD) technique. The x-raydiraction (XRD) analysis revealed that the c-axis orientation of the ZnO thin lms increasedwith increasing growth temperature. We demonstrated that ZnO thin lms can be grown at a lowtemperature of 100 C by using the MOCVD method. The room-temperature photoluminescencespectra of ZnO exhibited peaks in the violet region, as well as the ultraviolet region We have deposited ZnO thin lms on Si(100) substrates at low temperatures ranging from 25to 300 C by using the metalorganic chemical vapor deposition (MOCVD) technique.
