With a remarkable growth and expansion of Internet, the security issues emerged from intrusions and attacks such as computer viruses, denial of services and hackings to destroy information have been considered as serious threats for Internet and the private networks. To protect networks from those attacks, many vendors have developed various security systems such as firewalls, intrusion detection systems, and access control systems. However, managing those systems individually requires too much work and high cost. Thus, in order to manage integrated security management and establish consistent security management for various security products, the policy model of PN-ISMS (Policy Based Integrated Security Management System) has become very important. In this paper, present the hierarchical policy model which explore the refinement of high-level/conceptual policies into a number of more specific policies to form a policy hierarchy. A formal method of policy description was used as the basis of the mode in order to achieve precision and generality. Z-Notation was chosen for this propose. The Z-Notation is mathematical notation for expressing and communicating the specifications of computer programs. Z uses conventional notations of logic and set theory organized into expressions called schemas. 정보통신과 컴퓨터기술의 발전으로 인하여 불법침입으로 인한 정보 파괴, 서비스거부공격 그리고 컴퓨터 바이러스 등에 의한 역기능이 날로 증가하고 있는 추세이다. 또한, 이러한 공격들로부터 네트워크를 보호하기 위해서 침입차단시스템(일명:방화벽), 침입탐지시스템, 접근제어시스템 등 많은 보안제품들이 개발 및 적용되고 있다. 그러나 이러한 보안 제품들에 대한 관리를 위해서는 많은 작업과 비용이 소요된다. 따라서, 이들 보안제품들에 대한 효율적인 관리와 일관된 보안 정책을 적용할 수 있는 정책 기반의 통합보안관리시스템의 정책모델이 필요하게 되었다. 본 논문에서는 정책계층의 개념을 기반으로 상위계층의 추상적이고 개념적인 정책을 보다 구체적인 형태의 정책으로 정제(refinement)하는 정책기반의 통합보안관리시스템의 계층적 정책모델을 제시하였다. 정책의 정형화된 표현을 위해서 Z-Notation을 적용하였으며, 이는 수학적 논리와 집합이론을 기반으로 스키마형태로 표현된다.

Bridge - Treading was a flok festival that was held on the night of the 1st full moon of the lunar new years. Men and women, both young and old, took pan in it in the belief that crossing a bridge, or bridges, back and forth, the same number of times as the number of years they were old, on this night would prevent all types of leg and foot ailments from occurring throughout the coming year. The practice was carried on mainly around the Seoul central region of Korea. Though it has now largely disappeared, it has been reatores in the Yeoju area. According to the Korean almanac and other chronicles, it was once practiced throughout the land. It is in the preserved was brige-treading festival of yeoju, however, that both the original form, transmission, and function are clarified and brought to light. In this regard, when compares to similar festivals of other region such as Songpa and Kwacheon, it is found that of Yeojo has a special characteristic. Accompanied by folksongs, music, and dance, this was not a religions festival in the strict sense, but rather an annual custom filled with mirth and merriment that formed an integral part of Korean folk culture.

이동영(Dong-Yeong Lee),박기수(Ki-Soo Park),황선철(Sun-Chul Hwang),남대철(Dae-Cheol Nam),박진성(Jin-Sung Park),정순택(Soon-Taek Jeong),이영복(Young-Bok Lee),강병훈(Byeong-Hun Kang),김동희(Dong-Hee Kim) 대한정형외과학회 2016 대한정형외과학회지 Vol.51 No.3

목적: 노동 시 경추의 지속적인 신전 또는 굴곡 자세를 필요로 하는 직업군에서 경추의 퇴행성 변화에 미치는 자세 및 위험 인자에 대해 알아보고자 한다. 대상 및 방법: 경추의 퇴행성 변화에 영향을 미치는 인자들에 대해 알아보기 위해 나이, 성별, 신장, 체중, 체질량 지수, 흡연, 당뇨, 노동에 종사한 시간, 그리고 노동 시 반복적으로 요구되는 경추의 자세에 대해 조사하였다. 또한 83명의 경추 굴곡군과 83명의 경추신전군에 대해 퇴행성 변화 정도를 평가하기 위하여 측면 단순 방사선 사진에서 경추 퇴행성 지표를 이용하여 퇴행성 정도를 점수화(0-60점)하여 분석하였다. 결과: 경추의 퇴행성 지표는 굴곡군 7.8±6.2점, 신전군 12.2±6.0점으로 신전군에서 퇴행성 변화가 진행되어 있었다. 경추 퇴행성 변화의 위험 인자를 알아보기 위하여 시행한 multiple linear regression test에서 나이(p=0.004), 당뇨(p=0.029), 그리고 경추의 신전자세(p<0.001)가 퇴행성 변화에 영향을 미치는 것으로 나타났다. 결론: 노동 시 반복적인 경추의 신전 자세와 당뇨의 이환은 경부 척추증 진행에 유의하게 영향을 미치므로 이에 대한 적극적인 의학적 관리와 노동 시 자세 관리에 대한 교육이 필요할 것으로 생각된다. Purpose: The purpose of this study is to determine the relationship between the repetitive flexion or extension posture on the cervical spine on labor and degenerative change of the cervical spine, and the factors affecting degenerative change of the cervical spine. Materials and Methods: To determine the factors affecting degenerative change of the cervical spine, age, sex, height, weight, body mass index, smoking, diabetes mellitus (DM), time engaging in labor, and cervical spine posture (flexion or extension) required repetitively on labor were investigated in the subjects. In addition, to evaluate the level of degenerative change of the cervical spine on 83 people in the flexion group (flexion strain) and 83 people in the extension group (extension strain), cervical degenerative index (CDI) in the simple cervical spine lateral radiograph was used to score (0-60 points) the degenerative severity. Results: A total of 166 subjects (flexion group: 83 people, extension group: 83 people) participated in this study, and for the CDI, the cervical spine flexion group scored 7.8±6.2 points, and the cervical spine extension group scored 12.2±6.0 points to show that the cervical spine extension group had significant degenerative change in the cervical spine. In the multiple linear regression test performed to verify the risk factors affecting the degenerative change of the cervical spine, age (p=0.004), contraction of DM (p=0.029), and extension posture of cervical spine (p<0.001) influenced the degenerative change of the cervical spine. Conclusion: Repetitive extension posture on the cervical spine on labor and contraction of diabetes affected degenerative change of the cervical spine, therefore, training in medical care and posture on labor are required to prevent the progression of degenerative change in the cervical spine.

Objectives: The purpose of the present study was to review published studies comparing posterolateral complex (PLC) repair with PLC reconstruction in patients with PLC injury. Methods: Several electronic databases were queried for articles published until June 2018 that evaluated outcomes of posterolateral complex repair or reconstruction in patients with PLC injury. Data searches, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines, and the clinical outcomes were evaluated using various outcome values. The results are presented as the mean difference (MD) for parametric outcomes with 95% confidence intervals (CIs) and the risk ratio (RR) for non-parametric outcomes with 95% CIs. Results: Three comparative studies were included. There were no significant differences in clinical outcomes such as IKDC score (MD= 2.30, 95% CIs= -3.79 to 8.40, I2=0%),Lysholmkneefunctionscore(MD= -0.87, 95% CIs= -6.06 to 4.32, I2=0%) and complications (MD= -0.87, 95% CIs= -6.06 to 4.32, I2=0%). However, there was significant difference in failure rate after PLC surgery between repair and reconstruction (MD= 4.02, 95% CIs= 1.51 to 10.73, I2=0%). Conclusions: Although there were no significant differences in clinical outcomes between two groups, there was significant difference in failure rate after PLC surgery. It is believed that this could affect long-term clinical results and require further research.

Objectives; The time of return to play after modified Brostrm operation remains uncertain. The purpose of the present study was to review published studies regarding the return to play after modified Brostrm operation in patients with chronic lateral ankle instability. Methods; Several electronic databases were queried for articles published until June 2019 that evaluated outcomes of return to play after modified Brostrm operation in patient with chronic lateral ankle instability. Only clinical studies written in English were included. Data searches, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines, and the clinical outcomes were evaluated using various outcome values such as clinical scoring, complication, and return to play timeline data. Results; Five studies were included. Due to insufficient data description, a quantitative analysis has not performed. The preset study revealed the modified Brostrm operation has demonstrated favorable clinical outcomes and low complication rate. Related to return to play, the mean length of time was expected return to comparative sports play at approximately 14 weeks. Conclusion; The modified Brostrm operation is a safe and effective treatment for chronic lateral ankle instability providing a stable ankle and expected return to comparative sports play or training at approximately 14 weeks. This finding should be interpreted with caution because the data involved were extracted from only a few studies and high heterogeneity of included studies.

이동영(Dong Yeong Lee),황선철(Sun Chul Hwang),남대철(Dae Cheol Nam),정진훈(Jin Hoon Jeong),최영락(Young Lac Choi),박진성(Jin Sung Park) 대한정형외과학회 2015 대한정형외과학회지 Vol.50 No.4

목적: 원위 요골 골절 환자의 치료 후 발생할 수 있는 손목 관절 강직에 영향을 미치는 위험 인자를 알아보고자 한다. 대상 및 방법: 원위 요골 골절로 진단받은 후 수술적 치료를 시행한 환자 55명을 대상으로 하였다. 손목 강직 발생에 영향을 미칠 수 있는 다양한 인자들이 고려되었으며, 로지스틱 회귀 분석을 이용하여 95% 신뢰구간에서의 odds ratio (OR)를 계산하였다. p-value가 0.05 미만에서 유의한 것으로 판단하였다. 결과: 골절의 정복 정도를 반영하는 방사선적 지표 중 수술 직후와 6개월째 척골 변이만이 손목 강직과 관계가 있었다(p<0.05). 단변량 분석에서 환자의 연령(p=0.037; OR, 1.051)과 당뇨의 이환(p=0.016; OR, 8.000)이 손목의 강직과 관계 있는 것으로 나타났다. 강직에 영향을 미칠 수 있는 여러 인자들을 함께 고려한 다변량 분석을 시행한 결과에서는 오직 당뇨의 이환(p=0.034; OR, 6.588)만이 강직의 발생과 관계가 있었다. 결론: 원위 요골 골절 환자의 수술적 치료 후 손목 강직을 예방하기 위해 당뇨병의 이환 여부가 중요하다. 또한 골절의 정복시 척골변이의 정확한 해부학적 복원은 추후 발생 가능한 강직을 예방할 수 있는 중요한 인자로 생각된다. Purpose: The purpose of this study is to evaluate risk factors for wrist stiffness after treatment of distal radius fractures. Materials and Methods: A total of 55 consecutive patients who were diagnosed with distal radius fracture at the current authors’ institution and followed-up for at least 6 months were included in this retrospective study. Data on all factors related to wrist stiffness were considered. The degree of association for each of the factors was determined by calculation of the odds ratio (OR), with a 95% confidence interval. Logistic regression analyses were performed. p-value was set below 0.05. Results: Among radiologic indexes reflecting the degrees of fracture reduction, only ulnar variance showed significant association with wrist stiffness of distal radius fracture (p<0.05). In univariate analysis, age (p=0.037; OR, 1.051) and diabetes mellitus (DM) (p=0.016; OR, 8.000) showed significant association with wrist stiffness. Various factors significant at the p-value less than 0.20 level in univariate analyses were included in the multivariate analyses. In multivariate analyses, only DM (p=0.034; OR, 6.588) showed significant association with wrist stiffness. Conclusion: Contraction of DM is critical to avoid wrist stiffness of distal radius fracture patients. In addition, ulnar variance was considered a significant factor of wrist stiffness in distal radius fracture patients, thus reduction of fracture could be done more in proximity to normal anatomy.
