There are cases that revoke the certification because of disclosure of private key, deprivation of qualification and the expiration of a term of validity based on PKI. So, a user have to confirm the public key whether valid or invalid in the certification. There are many method such as CRL, Delta-CRL, OCSP for the cert-validation of certification. But these method many problems which are overload traffic on network and the CRL server because of processing for cert-validation of certification. In this paper we proposed the realtime cert-validation of certification method which solved problems that are data integrity by different time between transmission and receiving for CRL, and overload traffic on network and the CRL server based on DARC.

This paper examines gender trouble in the future society from Huxley's Brave New World, in which science is highly developed. In addition, I examined how gender equality was achieved in the World State in which equality and identity were emphasized, and considered the precise meaning of gender equality. Superficially, there are many gender inequality factors in the Reservation, and gender equality is achieved in the World State. However, if we look closely at the World State, we realize that they deprive individual rights under the name of social stability. Therefore, we should reconsider what real gender equality is, and we need to examine what is needed to achieve gender equality.

Diamino-diphenyl-sulfone (Dapsone) is widely used in the treatment of leprosy and a variety of blistering skin diseases. It sometimes has adverse side effects with common usual doses, such as skin, nervous system, gastrointestinal tract, liver, kidney and hematologic toxicity. One of these side effects is a rare but serious hypersensitivity reaction called dapsone syndrome, which occurs several weeks after the initial administration of the drug and results in unpredictable, sometimes fatal outcomes. This report deals with a 13-year-old girl's case with typical features of dapsone syndrome that included fever, exfoliative dermatitis, jaundice, hemolytic anemia and pleural effusion after being treated with dapsone for four weeks.

Sleep deprivation may affect the brain functions such as cognition and, consequentoy, dynamics of the EEG. we examiced the effects of sleep deprivation on chaoticity of EEG. Five volunteers were sleep-deprived over a period of 24 hours, They were checked by EEG during two days, the first day of baseline period, EEGs were reorded form 16 channels for nonlinear analysis. We dmployed a method of minimum cmbedding dimension to calculate the first positive Lyapunov exponent. For limited noisy data, this algorithm was strikingly faster and more accurate than previous ones. Our results show that the sleep deprived volunteers had lower values of the first positive Lyapunov exponent at ten channels (Fp$\_$1/, F$\_$4/, F$\_$8/, T$\_$4/, T$\_$5/, C$\_$3/, C$\_$4/, P$\_$3/, p$\_$4, O$\_$1/) compared with the values of baseline periods. These results suggested that sleep deprivation leads to decreawe of chaotic activity in brain and impairment of the information processing in the brain. We suggested that nonlinear analysis of the EEG before and after sleep deprivation may offer fruitful perspectives for understanding the role o f sleep deprivation on the brain function.

This study is conducted to understand the meanings and nature of the experience of the physically abused children. This is a phenomenological study utilizing van Manen's method to present the children's inner world. The participants for this study were 10 children, in the age of 8 to 12, who were physically abused by their parents. Data were collected by using semi-structured interviews by the workers who regurally contacted children at the service agencies. Data were analyzed by using 'line by line' reflection by two graduate level students and by the researcher. Eight essential themes were drawn and used for the phenomenological understanding which reveals the meanings given by the children experiencing abuse. There were some suggestions for the abuse counsellors based on these findings.

상속결격이란 피상속인이 상속할 순위에 있지만 그 자가 피상속인 등의 생명침해 혹은 피상속인의 유언행위에 대해 고의로 위법한 침해를 한 경우에 상속인자격을 박탈하는 제도이다. 상속인에게 법정결격사유가 발생하면 그 상속인은 법률상 당연히 상속인 자격을 상실하게 된다. 이렇게 상속인자격을 상실한 자를 상속결격자라고 한다. 즉 윤리적 경제적 관계에 있는 피상속인과의 정당한 상속관계를 파괴하는 자에게 상속권을 인정하지 않는 일종의 제재를 가하여야 한다는 상식 속에 그 근거가 있다고 본다. 우리나라의 현행 민법 제 1004조에 상속인의 결격사유를 규정하고 있으나, 특히 유언장을 위조한 상속인은 제1004조 5호 규정에 의거 상속결격사유가 발생되는데, 상속결격은 일신전속권인 효과로 인하여 다른 상속인들에게 그 효과가 미치지 않기 때문에 결국 대습상속을 통하여 실질적으로 상속재산의 소유권행사를 할 수 있는 등 여러 가지 문제점을 안고 있어, 본 논문에서는 우리나라 상속결격제도의 문제점을 지적하고 그에 대한 개선방안을 제시하고자 한다.

The year 2016 in Cambodia witnessed the collapse of Cambodian democracy. Promising results in terms of fairness the communal elections achieved were eclipsed by the dissolution of the Cambodia National Rescue Party. With press and civil society also being silenced, the ruling Cambodian People's Party expects no more challenge to its authoritarian rule. The economy continued it growth in 2017. However, serious problems embedded in its structure threaten the likelihood of sustainable development. Cambodia with solid China backing began to amp up its voice on the international stage, heading to a head-on collision with big donators including the United States.

기존 안드로이드 응용프로그램에 대한 자원 접근 제어는 응용프로그램을 작성한 개발자가 XML 파일에 미리 선언한 권한을 검사하는 방식으로 이루어진다. 이 권한은 인스톨되는 시점에 사용자의 동의를 얻어 해당 응용프로그램에 수여되며 응용프로그램이 특정 권한을 의도적으로 사용자로부터 은닉하는 것을 방지할 수 있다. 하지만 사용자는 해당 응용프로그램에 허용하고자 하는 일부 권한만을 수여할 선택권이 없다. 선언된 모든 권한을 허락하거나 그렇지 않으면 아예 응용프로그램을 설치할 수 없게 된다. 또한, 응용프로그램에 부여한 권한을 변경할 수는 없고 박탈하는 방법은 응용프로그램을 삭제하는 방법밖에 없었다. 따라서 본 논문에서 제안하는 기법은 응용프로그램의 자원 접근을 사용자가 fine-grained 하게 제어할 수 있도록 하는 기법이다. 이를 위해 응용프로그램을 사용하는 시점에도 각 접근 권한을 '항상 허용', '항상 사용자가 확인' 그리고 '항상 거부'로 세부적으로 설정 및 변경이 가능하도록 하였다. 또한, MS Windows Vista 에서 적용하고 있는 '사용자계정컨트롤'(User Account Control)과 같이 응용프로그램이 요구하는 권한 중 '항상 사용자가 확인'으로 설정 된 권한은 요청 시점에 사용자에게 팝업을 띄워 접근 제어에 대한 가시성을 확보하여 사용자가 확인할 수 있도록 하였고 사용자가 이를 수락한 경우에만 해당 권한을 수여 받을 수 있도록 하였다.

The reverse of reinforcement technique was used in treating rumination of a 12-year old (estimated age) mentally retarded child in a residential setting. The subject's rumination pattern was first to vomit the food onto the floor and then to eat it back in several attempts. Consequently, the way to reverse the contingency of rumination in this child was to take away the discharge whenever rumination occurred. An ABAB single subject design was adopted to evaluate the treatment effect. In baseline 1 the frequency of his rumination for 2.5 hours after eating was an average of 46(range= 30-62), while decreased to 6.7 in treatment condition 1. However, when the discharge was not taken away in baseline 2, his rumination increased to 34 times and then decreased to zero to 1 time when the reverse of reinforcement was reinstituted in treatment condition 2. The results clearly indicate that the reverse of reinforcement which was implemented in the form of removing the discharge from the floor was successful. It was reported that the treatment effect has been maintained over 10 months post treatment.
