다양한 정보보호체계가 운영되고 있지만, 방화벽과 침입탐지시스템이 가장 많이 운영되고 있는 실정에서, 본 논문에서는 방화벽 관리자의 차단로그 분석을 효율적으로 지원하면서, 방화벽에 의해 차단되어 침입탐지시스템이 탐지하지 못해 관리자가 지나칠 우려가 있는 공격행위를 방화벽을 통해 인지할 수 있는 방안을 구성했다. 이를 통해 관리자는 침입탐지시스템과 함께 네트워크를 통한 스캔 및 DOS 등의 공격을 방화벽을 통해 인지할 수 있어 안정적인 네트워크 운영이 가능하다.

Based on previous studies that cognitive complexity and coping flexibility are closely related with psychological adaptibility, it can be inferred that they can influence management ability of countertransference in counselling. This study focused on the influence of counselor's cognitive complexity and coping flexibility on the management ability of countertransference in counselling. The survey was conducted on 128 (female 108, male 20) counselors of college counseling center, general counseling center, schools and hospitals. The study employed flexibility scale measures, interpersonal discrimination test, and countertransference factors inventory. The results was that the level of cognitive complexity did not influence countertransference ability whereas the level of coping flexibility influenced countertransference management ability. In multiple regression, it was evidenced that coping flexibility influence countertransference management ability more than cognitive complexity. In sum, our study indicate that coping flexibility is important to enhance the management ability of countertransference in counselling, and that related counsellor training program should be developed in the future.

Finding causes of workers' unsafe behaviors is important to prevent construction accidents because 80 percent of accidents occur by workers' unsafe behaviors. In this regard, this research aims to investigate possible reasons of workers' unsafe behaviors based on workers' cognitive process model using System dynamics. This study is based on two ways of workers' cognitive process which are in relation to hazard perception and failure of hazard perception. Based on existing literature, causal loops for workers' cognitive process are developed to explain workers' habituation by staying out of accidents, safety learning by experience, failure of hazard perception, and attitude change by accidents. The interactions between the developed loops provide managerial insights to reduce workers' unsafe behaviors from a safety manager's perspective including increasing the probability of workers' hazard perception through knowledge management, maintaining workers' positive attitude toward safety, and controlling first-line supervisors to eliminate workers' unsafe behavior. The research allows us to better understand the causes and solutions of workers' unsafe behaviors in workers' cognitive perspectives.

This study examined the correlation of educational experience with practical behavior in infection control. Subjects were 152 dental hygienists in Gwangju from September 15 to October 5, 2015. The ratio of dental hygienists educated on infection control was higher in those worked in dental care with 2~4 dentist for 2~5 years and lower in those worked in dental cared with 1 dentist for 2~5 years (p<0.05, p<0.001). The dental hygienists with or without educational experience in infection control exhibited the highest activity rate in hand wash and the lowest in face protection. Barrier in health belief, was lower with the need for education in infection control among the factors affecting on the activity in infection control. The activity was higher with susceptibility and cue to action (p<0.05). Based on the results, education program on infection control should be developed, and applied periodically and obligatorily for dentist and all staffs of dental care to remove susceptibility and barrier, and to enhance cue to action. This will result the effective control of infection by elevating the health belief.

The purpose of this study was to analyze the Correlation Analysis between Awareness of the Serious Disaster and Safety Consciousness of Construction Workers under the Act on the Punishment of Serious. A survey was conducted on construction workers, construction managers, and safety managers. The results of this study were as follows; The correlation analysis conducted among the three groups indicated a significant correlation, with safety managers demonstrating the highest correlation, followed by construction managers and construction workers, and all three groups exhibited a moderate correlation. The correlation analysis conducted for the entire group also revealed a significant correlation, and as the number of participants increased, higher correlation coefficients were observed. Furthermore, to ascertain the significance of the correlation coefficients, a comparison was made between the p-value and the significance level (α). Consequently, a p-value smaller than the significance level of 0.05 was obtained, leading to the rejection of the null hypothesis and the acceptance of the alternative hypothesis. Therefore, it can be concluded that there is a relationship between the level of awareness of the serious Accidents Punishment Act and the level of Safety Consciousness of Construction. One limitation of this study is that it relied on a subjective indicator through a survey, which may introduce variability in the difficulty level of the questionnaire items.

트래픽 패턴-맵(PatternMap)은 전체/세부 도메인별 보안 상황을 근원지/목적지 IP 주소 범위로 이루어진 그리드 상에 표현하여 관리자에게 네트워크 보안상황을 실시간으로 인지시키는 도구이다. 각각의 그리드는 근원지-목적지 간의 연결을 의미하며, 최다 점유를 차지하는 트래픽의 포트를 식별력을 갖는 색으로 표현한다. 이상 트래픽 현상의 검출은 가로 및 세로 열에 나타난 동일 색의 막대그래프(포트)의 개수와 그것의 합에 따라 결정되며, 그 결과로 선택된 세로 열과 가로 열을 활성화시켜 관리자에게 그 현상을 인지시킨다. 일반적으로 인터넷 웜이 발생할 경우에는 특정 근원지 열이 활성화되고, DDoS와 같은 현상은 목적지 열이 활성화되는 특징이 있다.

A considerable number of construction disasters occurs on pathway. A safety management in construction sites is usually performed to prevent accidents in activity areas. This means that safety management level of hazards on pathway is relatively minified. Many researchers have introduced that a hazard identification is fundamental of safety management. Thus, algorithms for helping safety managers' hazardous area identification is developed using automated data collection technology. These algorithms primarily search potential hazardous area by comparing workers' location logs based on real-time locating system and optimal routes based on BIM. And potential hazardous areas is filtered by identified hazardous areas and activity areas. After that, safety managers are provided with information about potential hazardous areas and can establish proper safety countermeasures. This can help improving safety in construction sites.

This paper introduces a network security situation awareness tool using a traffic pattern map which facilitates recognizing a current network status by extracting and analyzing predetermined traffic features and displaying an abnormal or harmful traffic which deteriorates network performance. The traffic pattern-map consists of $26{\times}26$ intersections, on which the occupancy rate of the port having maximum occupancy is displayed as a bar graph. In general, in case of the Internet worm, the source address section on the traffic pattern map is activated. In case of DDoS the destination address section is activated.

네트워크 보안 상황인지 기술이란 현재 네트워크에서 보안과 관련하여 무슨 일이 발생하고 있는 지를 관리자에게 인지시켜 주는 기술이다. 이는 침입탐지시스템이나 방화벽에서 수행하는 잠재적인 공격자의 패킷을 필터링하거나 보고하는 것과는 달리 현재 네트워크에서 발생하고 있는 상황(침입 또는 공격 등)을 알려주는 것에 초점을 맞춘다. 네트워크 보안 상황인지 기술에는 데이터 선정 및 수집, 특성 인자 추출, 연관성 분석, 데이터마이닝, 패턴분석, 이벤트시각화 등과 같이 매우 다양한 세부 기술들이 있지만, 본 고에서는 이벤트 종류에 따른 시각화 기술들의 현황과 ETRI에서 개발한 Visual Scope에 대해 살펴보고자 한다.
