We propose a correction security framework as next generation security technology to provide secure and reliable Internet services. The framework guarantees durability of the services in spite of external attack, intrusion, vulnerability for fault tolerance, and network management technology that covers the set of techniques aimed at providing rapid service recovery. The improvement technology includes system itself improvement and synamic improvement preventing faults from being re-activated, in cooperation with other systems such as vulnerability anaysis system, NMS, ESM. It is expected that our framework will be applied to global networks as well as system alone, and be able to guarantee the network survivability and reliable Internet services.

In correctional facilities with majority of occupants in custody, the safe evacuation guide without getaway accidents should be very important due to complexity in escape paths. Fire causes are various in correctional facilities, for example, arson fire is a major cause in mental treatment facilities, however, old facilities or carelessness of flammable materials consist of fire causes in jail facilities. Both types of correctional facilities are the same in terms of many casualties from the fire cases. The thesis focus on escape paths and evacuation guide plans on the basis of analysis on fire cases and structural vulnerability, and then an electronic unlocking system is concededly installed for safe evacuation of occupants in custody without getaway accidents. Especially, the effect of the electronic unlocking system is going to be analyzed on the basis of RSET (required safe egress time) in order to realize for the occupants to evacuate safely to the front yard in case of emergency. In conclusion, if electronic security allowed system with USN (Ubiquitous Sensor Networks) technology should be installed in multi-storey correctional buildings, it is proposed that the occupants in custody might be a guided safely without getaway trials.

The purpose of Emergency Medical System(EMS) is what a patient returns to society with recovering mental tone in the shortest time as giving prompt and proper medical treatment to patient in emergency situation, and the Correctional Administration(CA) is purposed for the convict to return and settle down to society after release from prison in success as executing schooling, enlightenment activity, vocational training to convict who was quarantined from the society for the term of imprisonment. The EMS and CA will coincide each other which is reverting people to society in safety. This study aims to suggest the developmental program of EMS in correctional facilities through the cause of emergency situation, system, human resources, establishment, medical equipments, state of budget and the point issue for safety of victim who has many chances that is exposed to physical damage and disease because of particularity of lower culture in correctional facilities and the staff who works there. First, in the view of the correctional facility security system, a proper number of the emergency rescuers should be employed. Second, the effective transportation system along with some emergency medical equipment needs to be established. Third, the correctional officers and the prisoners should be learned the first-aid training which is realistic, practical and systematic. Fourth, the cooperative system should be established such as 1339 emergency medical information center in society. Fifth, the Ministry of Health and Welfare must increase EMS budget for correctional facilities.

Recent changes in the information security environment have led to persistent attacks on intelligent assets such as cyber security breaches, leakage of confidential information, and global security threats. Since existing information security systems are not adequate for Advanced Persistent Threat; APT attacks, bypassing attacks, and attacks on encryption packets, therefore, continuous monitoring is required to detect and protect against such attacks. Accordingly, this paper suggests an operation plan for managing an information security system to block the attack routes of advanced persistent threats. This is achieved with identifying the valuable assets for prevention control by establishing information control policies through analyzing the vulnerability and risks to remove potential hazard, as well as constructing detection control through controlling access to servers and conducting surveillance on encrypted communication, and enabling intelligent violation of response by having corrective control through packet tagging, platform security, system backups, and recovery.

CAPTCHA 시스템은 스팸이나 로봇에 의한 자동 가입, 계정 생성 방지도구로써 인간의 우수한 가독성을 통해 특정 언어 또는 그림을 해독할 수 있는 특성을 이용한 것으로 일반적으로 컴퓨터 프로그램이 해독하기 어려운 기호, 글자 등을 재입력하도록 하여 스팸을 위한 자동화 도구 등을 무력화 시키는 보안 기술이다. 하지만 기존에 존재하였던 텍스트 기반의 시스템은 웹봇이나 머신 러닝등을 통하여 쉽게 통과할 수 있는 단점을 나타냈다. 우리는 이러한 단점을 보완하고자 새로운 이미지 기반의 CAPTCHA 시스템을 제안하였다. 제안된 시스템은 일반적인 사진에서 부분 이미지를 출력, 무작위 회전을 가하여 사용자에게 올바른 교정을 요하는 시스템이었다. 본 논문에서는 일반적인 사진에서 출력되는 부분 이미지의 형태를 다각형으로 추출하여, 사용자에게 좀 더 인식률을 높일 수 있는 서브 이미지의 형태를 찾고, 좀 더 효과적이고 실용적일수 있는 CAPTCHA 시스템을 제안하고자 한다. 본 논문에서 제공하는 다각형의 형태는 정사각형, 정오각형, 정육각형, 정칠각형 그리고 정팔각형이다. 총 5가지 형태의 다각형 중에서 사용자에게 가장 효과적인 다각형을 실험을 통하여 찾을 것이다.

The prior studies have well established the factors of correctional staff's stress at work. However, it is not clearly identified gender-specific factors influencing female correctional officers' level of stress. Thus, this study aims to examine factors particularly influencing female correctional officers' stress, such as child-rearing and work conflict, overwork bounden, and strains from male-oriented organizational culture. This current data utilized a set of survey data drawn from female correctional officers from 124 prisons located in different regions in this nation. Finally, a total of 172 female correctional officers's survey data was used for the analysis. A set of multivariate analyses reveal that security staff role, satisfaction for life, positive perception toward correctional officers' leadership in prison decreased the risk of stress among female correctional officers. Regarding work-job conflicts variables, child-rearing and work conflict and strains from male-oriented organizational culture were significantly associated with female correctional officers' stress. Yet, the direction of the two variables were different. For female officers, child-rearing and work conflict was not a risk factor for stress in that i decreased the level of stress. But the variable of strains from male-oriented organizational culture was a risk factor for female officers' stress level. Further suggestions for the future studies, discussion on contributions of the current study and policy implications were discussed in the last part of this article.

CAPTCHA is a security tool that prevents the automatic sign-up by a spam or a robot. This CAPTCHA usually depends on the smart readability of humans. However, the common and plain CAPTCHA with text-based system is not difficult to be solved by intelligent web-bot and machine learning tools. In this paper, we propose a new sub-image based CAPTCHA system totally different from the text based system. Our system offers a set of cropped sub-image from a whole digital picture and asks user to identify the correct orientation. Though there are some nice machine learning tools for this job, but they are useless for a cropped sub-images, which was clearly revealed by our experiment. Experiment showed that our sub-image based CAPTCHA is easy to human solver, but very hard to all kinds of machine learning or AI tools. Also our CAPTCHA is easy to be generated automatical without any human intervention.
