네트워크 위험 분석 및 취약점 점검 방법에 관한 연구

박원주,서동일 한국콘텐츠학회 2005 한국콘텐츠학회논문지 Vol.5 No.2

This paper proposes to analyze a security level about information property systems. This method uses objective and quantitative risk level assessment.The method analyzes administrative, physical and technical aspects of information property system commonly. This method also uses administrative, physical and technical weights individually according to requirements security assessment purpose. And it shows risks weighting mean and importance of information property by graph. The most right and up systems in maps is prior to other systems. Also, Quantitative analysis presents more objective and efficient results for security level assessment of information system. 기업 네트워크 환경 및 인터넷상에서 발생할 수 있는 보안상의 취약점들은 악의를 가진 내외부의 공격자들에게 악용될 가능성이 있다. 이러한 상황은 기업으로 하여금 정보 자산의 유출 및 파괴 등의 물리적인 피해와 더불어 복구를 위한 인력 및 시간의 소요 등 금전적인 손해를 야기시킨다. 이에 정확한 네트워크 보안 위험을 분석하여 이러한 피해의 가능성을 사전에 파악하고, 예방할 수 있는 방안을 마련하여 최대한의 보안성을 확보하여야 한다. 본 고는 이를 해결하기 위한 네트워크의 보안 수준을 측정하고 분석할 수 있는 국내에서의 접근 방법론을 살펴보고, 적절한 평가 절차 및 평가 수행 방법, 점검 항목을 도출한다.

박원주,조인호,Park, Won-Ju,Cho, In-Ho 대한치과보철학회 2009 대한치과보철학회지 Vol.47 No.4

Statement of problem: Problems such as loosening and fractures of retained screws and fracture of implant fixture have been frequently reported in implant prosthesis. Purpose: Implant has weak mechanical properties against lateral loading compared to vertical occlusal loading, and therefore, stress analysis of implant fixture depending on its material and geometric features is needed. Material and methods: Total 28 of external hexed implants were divided into 7 of 4 groups; Group A (3i, FULL $OSSEOTITE^{(R)}$Implant), Group B (Nobelbiocare, $Br{\aa}nemark$ $System^{(R)}$Mk III Groovy RP), Group C (Neobiotec, $SinusQuick^{TM}$ EB), Group D (Osstem, US-II). The type III gold alloy prostheses were fabricated using adequate UCLA gold abutments. Fixture, abutment screw, and abutment were connected and cross-sectioned vertically. Hardness test was conducted using MXT-$\alpha$. For fatigue fracture test, with MTS 810, the specimens were loaded to the extent of 60-600 N until fracture occurred. The fracture pattern of abutment screw and fixture was observed under scanning electron microscope. A comparative study of stress distribution and fracture area of abutment screw and fixture was carried out through finite element analysis Results: 1. In Vicker's hardness test of abutment screw, the highest value was measured in group A and lowest value was measured in group D. 2. In all implant groups, implant fixture fractures occurred mainly at the 3-4th fixture thread valley where tensile stress was concentrated. When the fatigue life was compared, significant difference was found between the group A, B, C and D (P<.05). 3. The fracture patterns of group B and group D showed complex failure type, a fracture behavior including transverse and longitudinal failure patterns in both fixture and abutment screw. In Group A and C, however, the transverse failure of fixture was only observed. 4. The finite element analysis infers that a fatigue crack started at the fixture surface. Conclusion: The maximum tensile stress was found in the implant fixture at the level of cortical bone. The fatigue fracture occurred when the dead space of implant fixture coincides with jig surface where the maximum tensile stress was generated. To increase implant durability, prevention of surrounding bone resorption is important. However, if the bone resorption progresses to the level of dead space, the frequency of implant fracture would increase. Thus, proper management is needed.

Seroprevalence of Respiratory Syncytial Virus IgG among Healthy Young Adults in Basic Training for the Republic of Korea Air Force

박원주 대한의학회 2014 Journal of Korean medical science Vol.29 No.9

This investigation enrolled 570 healthy young males gathered from all over the country formilitary service at the Republic of Korea Air Force boot camp. It confirmed RSV IgGseroprevalence by utilizing the enzyme immunoassay method just prior to undergoingbasic training. The mean age of this study was 20.25 ± 1.34 yr old. The results of theirimmunoassay seroprofiles showed that 561 men (98.4%) were positive, 2 (0.4%) werenegative and 7 (1.2%) were equivocal belonging to the grey zone. It was confirmed thatRSV is a common respiratory virus and RSV infection was encountered by almost all peoplebefore reaching adulthood in Korea. Nine basic trainees belonging to the RSV IgG negativeand equivocal grey zone categories were prospectively observed for any particular vulnerabilityto respiratory infection during the training period of two months. However, these ninemen completed their basic training without developing any specific respiratory illness.

정서억제가 우울 및 불안에 미치는 영향: 눈치의 조절효과

박원주 한국상담학회 2017 상담학연구 Vol.18 No.4

This study aimed to examine the moderating effects of nunchi on the relationship between emotional suppression and depression and anxiety. For this purpose, an online questionnaire survey measuring emotion suppression, nunchi, depression and anxiety was conducted to 180 adult males and females over 20 years old who attended H cyber university in Seoul, South Korea. To test moderation effects, hierarchical multiple regression analysis entering emotion suppression, nunchi, and their interaction terms were conducted. As the result, the moderating effects of nunchi in the relationship between emotional suppression and depression and anxiety were significant. it was proved that nunchi mitigates the effects of emotion suppression on depression and anxiety. Specific interaction patterns were examined by simple slope analysis, and implications of the research findings and counseling intervention were discussed. 본 연구의 목적은 정서억제와 우울 및 불안의 관계에서 눈치의 조절효과를 검증하는 것이다. 이를 위해 서울시에 소재하는 H사이버대학교에 재학 중인 20세 이상 성인남녀 180명을 대상으로 정서억제, 눈치, 우울 및 불안을 측정하는 설문지를 온라인상에서 실시하였다. 조절효과를 검증하기 위해 정서억제, 눈치, 이들 간의 상호작용 항을 투입하여 위계적 회귀분석을 실시하였다. 연구 결과, 정서억제와 우울 및 불안의 관계에서 눈치의 조절효과는 유의미하였는데, 눈치는 정서억제가 우울 및 불안에 미치는 영향을 완화시키는 것으로 검증되었다. 이들의 상호작용 패턴에 대해 기울기 비교를 통해 확인하였으며, 이러한 결과의 의미와 상담적 개입법에 대한 함의를 논의하였다.

클라우드 서비스 파트너 역량 분석 프레임워크 개발

박원주,서광규,Park, Wonju,Seo, Kwang-Kyu 한국반도체디스플레이기술학회 2022 반도체디스플레이기술학회지 Vol.21 No.3

The application of cloud computing to many industrial domains is rapidly increasing, and domestic and foreign cloud service providers are actively conducting business. In the domestic cloud market, it is necessary to establish an ecosystem with partner operators that work closely with private cloud service providers. In this paper, to create such an environment, we propose a framework that can evaluate the capabilities of partners required for cloud service providers to establish specific business strategies. The framework proposed in this study establishes criteria for evaluating partners' competencies and applies a decision-making model such as fuzzy AHP for evaluation. Eventually this will help not only to expand the domestic cloud market but also to strengthen the competitiveness of domestic cloud partners through the growth of the domestic cloud market.

In Korea, where the world's first cloud computing development law was created, cloud service technology has been developing so far, and the industries to which artificial intelligence and big data technologies can be applied based on this are increasing. It is important for domestic and overseas cloud operators to secure many partners in order to provide optimal services to users. It is also important to systematically develop the partner's technology and discover new partners. In particular, the public, medical, and financial sectors are industrial fields that are difficult for domestic as well as global cloud service providers to expand without the help of partners. This study analyzes partner policies for industries caused by domestic regulations through domestic and foreign cases, and aims to establish partner management policies optimized for the domestic environment.
