During the course of analysing both single-dish and very long baseline interferometry (VLBI) data obtained from the Korean VLBI Network (KVN), we found a systematic oset between ux density measurements from dierent antennas. We were able to attribute a majority of the systematic osets to changes in the \a priori" antenna gains, which were found to have varied up to 10 percent at 22 GHz and up to 30 percent at 43 GHz. Using historical calibrator observations, we present a revised set of gains that may be applied to KVN data taken from 2015 August to 2019 January. Application of the revised gains to the KVN results in a consistency of correlated ux density measurements between the three baselines of approximately ve percent. We found that images from the recalibrated data typically have a 50 percent higher dynamic range, with some cases showing an increase of dynamic range of up to a factor of three.

Reanalysis using the US Food and Drug Administration Hazard Analysis method was performed to evaluate the effectiveness of the current Critical Control Point (CCP) configuration for non-thermal processes such as meat packaging plants and butcher shops. During non-heat treatment processing without the process of removing or reducing contaminated microorganisms, it is necessary to set and control the incoming material inspection step with the CCP since this step is essential to prevent the inflow of contaminants through incoming materials. The temperature control of the final product storage refrigerated room can be managed by the prerequisite program. However, the CCP setting of the refrigerated room prior to shipment of the meat packaging plant in which the cold chain system should be maintained in the following distribution stage is recognized. It is not an effective method to install a metal detector and manage it with CCP for metal hazard control. Improving hygienic cleaning guidelines and enhancing hygiene training are proactive and effective measures against metal particle contamination.

One of the issues that has influenced correctional policy since the 1970s has been the evaluation of the outcome of correctional treatment programs. While the public supports the concept of rehabilitation and correctional officials value them as effective means of changing inmates, there should at least exist an expectation that those programs will reduce recidivism. The ‘nothing works doctrine’, derived from Martinson's article, contributed in the disappearance of expectation and faith for correctional treatment programs. The reasons why Martinson's article of 'nothing works' have been so influential to academic as well as societal and political areas are explained in various respects: social and political climates of the 1960s-1970s characterized by anti-war moods, racial problems, poverty issues, and women's liberation, the changes of middle-class & liberal criminologists' attitudes towards crime and crime control, the politicization of crime problems, the domination of sociological approaches in criminology, and the lack of knowledge and skills in crime predictions by academics. In the US, rehabilitation as a correctional ideology had been retreating since early 1970s and almost disappeared in the mid 1980s as a goal of punishment, indicating that the retribution paradigm had returned. It is persuasive that such shifts resulted from political and societal reactions of conservatives and liberals toward crime, and are shown in correctional areas. In this context, some scholars has said that the society must move beyond the naivete and exuberance that marked the advocacy of rehabilitation in the 1950s and early 1960s and beyond the cynicism and pessimism that has reigned for much of the last three decades.(Palmer, 1992) This notion has received widespread support. New evaluation studies, including meta-analyses done after Martinson's article in 1974, indicate that correctional treatment programs could be effective in reducing criminal recidivism. And they have demonstrated that juvenile correctional intervention is more effective than intervention programs designed for adults. It has been known that behavioral/cognitive treatment, on average, produces larger effects than other treatment. Intensive, in-prison drug treatment is effective, especially when combined with community aftercare. Education, vocational training, and prison labor programs have modest effects on reducing criminal recidivism and increase positive behavior in prison. Evidence on sex offender treatment intervention program is less positive, probably because the target population is heterogeneous and treatment needs to be tailored to specific offender deficits.(Gaes et al., 1999) The results of meta-analyses seem to show that the programs for probationers or juvenile offenders with community aftercare are inclined to be more effective. There have been major theoretical and methodological advances in the juvenile and adult correctional treatment literature since Martinson's assessment study. Expecially, adaptation of the psychological learning model and meta-analysis as a statistical technique to criminology and corrections have been known to contribute in formulating principles for successful treatment programs though those principles need further clarification and empirical assessment. The following are suggested as principles of successful correctional treatment: linkage with criminogenic needs, multimodal programs for various deficits, matching client learning styles with staff teaching styles, treatment based on risk differentiation, providing skills oriented to cognitive-behavioral treatment, implementing programs with continuity of care and sufficient dosage, and involvement in both program development and evaluation by researchers.

To reveal the linkage relationship between the Ms locus, a restorer-of-fertility gene for cytoplasmic male-sterility (CMS) caused by CMS-S cytoplasm in onion (Allium cepa L.) and previously reported molecular markers linked to the Ms locus, 11 recombinants selected from 4,273 segregating plants originating from the cross between male-sterile maternal and male-fertile paternal lines were analyzed. Results showed that genotypes of a codominant marker, jnurf12, were perfectly matched with the male-fertility phenotypes in all recombinants, but that this marker was not applicable in diverse breeding lines due to multiple band patterns. For the development of more reliable markers, a 12-bp indel was identified from the sequences which were obtained by genome walking, and was used to develop a simple PCR marker which was designated jnurf13. When 104 diverse breeding lines containing CMS-S cytoplasm were analyzed with the jnurf13 marker, male-fertility phenotypes of all breeding lines were perfectly matched with marker genotypes. To our surprise, phenotypes of 153 breeding lines containing CMS-T-like cytoplasm were also matched with genotypes of the jnurf13 marker which was linked to the Ms locus for the CMS-S system. Furthermore, phenotypes of four F2 populations containing CMS-T-like cytoplasm co-segregated perfectly with jnurf13 genotypes. Allelic segregation distortion was detected in two F2 populations using the jnurf13 maker. The results of this study were in conflict with a previous model for inheritance of fertility restoration in the CMS-T system. Therefore, we proposed a new model based on the data analyzed with the jnurf13 marker, which was in linkage disequilibrium with restorer-of-fertility genes for both CMS systems.

댐이 위치하고 있는 유역에서도 신규 수자원 확보에 대한 필요성은 계속 제기되어왔고, 이에 따라 기존 댐에 대한 용수공급능력의 재평가의 필요성도 제기되어져 왔다. 본 연구에서는 댐의 하류 용수수요 증가에 따른 추가용수공급 가능 여부를 판단하기 위하여 다목적댐의 용수공급능력을 재평가하였고, 이에 따른 추가용수공급 가능량을 산정하였다. 대상댐은 낙동강의 안동댐 및 임하댐을 선정하였다. 저수지운영모형으로는 표준운영률을 사용한 모형과 HEC-ResSim을 사용하였으며 1979년부터 2008년까지 30년 동안 저수지 단독운영을 실시하였다. 본 연구에서 용수공급능력의 평가기준인 이수안전도는 신뢰도 96.7%, 95.0%의 연단위 및 월단위 평가를 기준으로 설정하였다. 신뢰도 95.0%의 연단위 평가 시 안동댐의 경우 용수공급 가능량이 연간 893백만m3로 산정되었고, 임하댐의 경우 연간 382백만m3로 산정되어 안동댐 및 임하댐 모두 기본계획공급량에 비하여 용수공급능력이 부족한 것으로 나타났다.
