Taking the perspective of children's welfare, this study aimed at critically analyzing the system of notification disposition which institutionalized children have experienced. Notification disposition is a juvenile justice process that, when a child (10 th 18 years old ) has been delinquent or is at risk for delinquency, is initiated without investigation or prosecution procedures by direct notification to a judge from the caregivers, school principals, chief probation officers, or directors of child care institutions. The data used in the analysis included case records of probation offices, and court sentencing documents of juvenile protective dispositions. Results showed that notification cases were initiated by directors of child shelters/care institutions. The most common reasons of notification were theft, runaway, physical violence, drinking, and smoking. Furthermore, there were more controversial reasons, such as "bad influence on another institutionalized children", "showing no remorse", "no sense of guilt"and "challenge of rearing in institutions" Based on the results, we discussed three problematic aspects of the direct notification system by directors of childcare institutions : (1) too much reliance on the judicature judgment of juvenile court; (2) less stability of the judicial status of notified children, and (3) inadequacies of the notifying eligibility for directors of child care institutions.

This study developed a relapse prevention program for substance abusing women and evaluated its effectiveness. The major contents of the program include to enhance cognitive and behavioral coping skills, to identify and expand supportive social networks, and to deal with women-related issues. The program was operated 3 times with 24 female clients in a probation office in Seoul from August 2003 to October 2004. The program changed the participants' attitudes toward substance use and improved their drug-refusal skills. This study mentions that the findings may be useful for practitioners as well as researchers because this study was first one that dealt with a women-only group in Korea. Finally, this study suggests that more studies be conducted in order to provide better understandings on substance abusing women and more effective interventions skills.

This study aims to compare the differences of crucial factors that are associated with probation warning tickets between sex offenders and non-sex offenders in South Korea. Serious high-profile cases have occurred in recent years which resulted in public and political conners for successful sex offender management and monitoring strategy through community corrections. The official response has been to initiate a series of legislative probation and parole measures by using GPS electronic monitoring system, chemical castration, and sex offender registry and notification. In this context, the current study is designed to explore the major factors that could affect the failure of probation by comparing the differences between sex offenders and non-sex offenders in terms of their major factors which are related to the failure of probation. The failure of probation is measured by the number of warning tickets which would be issued when there is the violation of probation conditions. The data is obtained from Seoul Probation office from January, 29, 2014 to February, 28, 2014. The sample number of sex offenders is 144 and the number of non-sex offenders is 1,460. The data includes the information regarding the offenders who completed their probation order after they were assigned to Seoul Probation in 2013. Furthermore, this study uses the chi-square and logistic regression analysis by using SPSS statistical package program. The result demonstrated that only prior criminal history was statistically significant factor that was related to the number of warning tickets in the sex offender group when other variables were controlled($X^2=25.15$, p<0.05, Nagelkerke $R^2=0.23$)(b=0.19, SE=0.08, p<0.05). By contrast, there were various factors that were associated with the number of warning tickets in non-sex offender group. Specifically, the logistic regression analysis for the non-sex offenders showed that demographic variable(marital status and employment type), offender-victim relationships, alcohol addiction, violent behavior, prior criminal history, community service order, and attendance order were statistically significant factors that were associated with the odds of warning tickets. Further policy implication will be discussed.

The purpose of this study is to apply a probation and tea culture therapy convergence program developed for the self-esteem improvement and recidivism prevention of sex offenders supervised by GPS electronic monitoring(wearing electronic anklet). After applying the tea culture therapy program, this study examines the effect of the program on the self-esteem improvement of sex offenders with electronic anklet. This study employs an integrative approach of qualitative and quantitative methods. It was shown from the qualitative analysis that the participants have considerably more positive attitudes, active participation, seriousness in interpersonal relationship, anger management, and sympathy after the program. The results from quantitative analysis indicate that the self-esteem of participants are significantly improved.

This paper was written to present the recent trend of juvenile delinquency within the context of family system and to provide the role and tasks of Family Science in the area of Probation and Parole System in Korea. Since Family Science provides knowledges and skills to help for both adolescents and their families by improving interactional functions, the role of Family Science was focusing more on comprehensive and integrated perspectives. The tasks of Family Science, especially, in family life education, family therapy, and family policy, were as follows: 1) to prevent recurrence of misbehavior by family life education. 2) to draw the cooperation with the judicial system. 3) to provide the advanced course for volunteers. 4) to perform crime prevention education for normal adolescents. 5) to join the official education for civil service personnel. 6) to manage group-homes after the completion of the probation period.

Three types of socio-moral transgression events were used to test the moral emotions and attributions of 30 juvenile offenders on probation with a comparison group of 30 non-offenders. Data were analyzed by chi-square. Differences between juvenile offenders on probation and non-offenders were that juvenile offenders expected victimizers would feel happier and less guilty following such acts of victimization as physical harm, theft, and lying than the comparison group. Non-offenders were more likely than offenders to feel that victims would feel angry and upset. Juvenile offenders gave more variable and less adaptive emotional responses. Offenders provided victimization and emotional distance attributions, but the comparison group provided moral attributions or causal-dependent attributions such as fairness and justice.

Mesna has been used with ifosfamide to prevent urotoxicity in the treatment of testicular cancers. This drug also protected the toxicities of adriamycin without compromising cytostatic activity. With an idea of radioprotective role of sulfhydryl group of radioprotectors and of mesna decreasing the toxic effect of adriamycin which produces free radicals, mesna and radiation were administered to mice to study the protective effect of this drug and to identify the difference in regenerative capacity of the germ cells in the testis between radiation-treated and both mesna-and radiation-treated groups. The shape and numbers of spermatogenic cells in the seminiferous tubules were examined every week after irradiation. In both groups, initial reduction and later recovery in germ cell numbers and shape was observed. The lowest germ cell number was found around three weeks after irradiation. Mean germ cell number of the mesna-treated group was significantly higher than radiation-treated group at all observed periods (p<0.05). More competent regeneration was present in mesna-treated group. These results suggest that mesna protect the testis from radiation injury. Further study will be necessary to identify whether mesna protects other tissues from radiation and it does not hamper tumor control.

IIIN계 물질 기반의 광 반도체는 직접 천이형 넓은 밴드갭 구조를 갖고 있기 때문에 적외선부터 가시광선 및 자외선까지를 포함한 폭 넓은 발광파장 조절이 가능하여 조명 및 디스플레이 관련 차세대 광원으로 많은 관심을 받고 있다. 일반적인 청색 및 녹색 발광영역의 활성층으로는 InGaN/GaN 다중양자우물구조를 사용하고 있으나, 장파장의 녹색 발광을 얻기 위해서는 인듐의 함유량이 증가하여야 한다. 하지만, 인듐의 함유량이 증가함에 따라서 InGaN/GaN 다중양자우물 구조내에서 인듐의 편석현상의 발생이 용이하게 되어 계면 특성을 저하할 뿐 아니라, 비발광 센터를 증가하여 발광 효율을 급격히 감소시키는 원인이 되고 있다. 또한, InGaN과 GaN의 큰 성장온도의 차이에 따라 800도 부근의 저온 영역에서 성장된 InGaN층이 1,000도 이상의 고온 영역에서 GaN층이 성장시 InGaN층의 열화 현상이 급격히 발생되고 있다. 이를 억제하기 위해서 금속유기화학증착법의 성장 변수 최적화, 응력제어, 도핑 등의 편석 억제기술 및 보호층이 사용되고 있다. 본 연구에서는 인듐함유량이 증가된 녹색 InGaN/GaN 다중양자우물구조에서 InGaN 우물층 상하부에 도입된 GaN 보호층에 따라 발생되는 양자우물구조의 광학 및 결정학적 특성 분석을 통해 GaN 보호층의 역할을 분석하고자 한다. 본 연구에서는 금속유기화학증착장치를 이용하여 사파이어 기판위에 GaN 템플릿을 성장하고, n-형 GaN, InGaN/GaN 다중양자우물구조 및 p-형 층을 성장하였다. 앞선 언급하였듯이, InGaN/GaN 다중양자우물구조내에 GaN 보호층의 역할을 규명하기 위하여 샘플 A의 경우는 보호층이 전혀 없는 구조이고, 샘플 B의 경우는 InGaN 우물층의 상단부에만, 샘플 C의 경우에는 우물층 상부 및 하단부 모두에 약 2.0 nm 두께의 GaN 보호층을 형성하였다. 이 보호층의 유무에 따른 다중양자우물구조의 계면 특성을 확인하기 위한 X-선 회절을 이용하였고, 광학적 특성을 확인하고 상온 포토루미네선스법을 이용하여 녹색 발광 파장의 변화 및 발광세기를 관찰하였다. 우선적으로, 상온 포토루미네선스법을 이용하여 각 샘플의 발광특성을 확인한 바 상하부 모두에 GaN 보호층이 존재하는 샘플 C의 경우 약 510 nm 부근에서 발광이 관찰되었지만, 상단부에 GaN 보호층이 존재하는 샘플 B는 약 495 nm영역에 발광이 확인되었다. 특히, 전혀 보호층이 존재하지 않는 샘플 A의 경우 약 440 nm에서 발광하는 현상을 관찰하였다. 이는 우물층 상단부 및 하단부에 존재하는 GaN 보호층이 In의 확산을 억제하는 것으로 판단된다. 또한, 발광파장 및 세기를 확인한 바, 보호층의 존재하지 않을수록 단파장화가 발생함에도 불구하고 발광세기는 급격히 약해지는 것으로 보아 계면특성이 저하되어 비발광센터가 증가되는 것으로 판단된다. 이를 구조적으로 확인하기 위하여 X-선 회절법을 통한 ${\omega}$/$2{\Theta}$ 스캔의 결과는 In의 0차 피크가 GaN 보호층이 없을 경우 GaN의 피크 방향으로 이동하는 것으로 보아 GaN 보호층은 우물층 성장 후 GaN 장벽층을 성장하기 위해 온도를 증가시키는 과정에서 In의 확산되는 것으로 판단된다. 또한, 하부 GaN 보호층의 경우 GaN 장벽층 성장 후 온도를 감소시키는 과정에서 성장되므로, 우물층으로부터 In의 탈착현상이 아닌 장벽층과의 상호 확산으로 판단된다. 또한, 계면특성을 확인하기 위해 InGaN의 X-선 위성 피크를 확인한 바 샘플 A의 경우 매우 넓고 약한 피크가 관찰된 반면, 보호층이 존재하는 샘플 B와 C의 경우 강하고 얇은 피크가 확인되었다. 이는 GaN 보호층의 도입으로 인해 계면특성이 향상되는 것으로 판단된다. 따라서, 우리는 InGaN/GaN 다중양자우물구조에서 GaN 보호층은 상부의 열화 억제 뿐아니라, 하부의 장벽층 및 우물층 사이의 상호확산을 억제하는 GaN 보호층의 도입을 통하여 우수한 계면 특성 및 비발광센터의 억제를 얻을 수 있을 것으로 생각되며, 이는 향후 GaN계 발광다이오드의 전계 발광특성을 증가하여 우수한 발광소자를 개발할 수 있을 것으로 기대된다.
