The event-free survival (EFS) for pediatric acute lymphoblastic leukemia (ALL) has shown remarkable improvement in the past several decades. In Korea also, a recent study showed 10-year EFS of 78.5%. Much of the improved outcome for pediatric ALL stems from the accurate identification of prognostic factors, the designation of risk group based on these factors, and treatment of appropriate duration and intensity according to risk group, done within the setting of cooperative clinical trials. The schema of first-line therapy for ALL remains mostly unchanged, although many groups have now reported on the elimination of cranial irradiation in all patients with low rates of central nervous system relapse. Specific high risk subgroups, such as Philadelphia chromosome-positive (Ph+) ALL and infant ALL continue to have significantly lower survival than other ALL patients. The introduction of tyrosine kinase inhibitors into therapy has led to enhanced outcome for Ph+ ALL patients. Infant ALL patients, particularly those with MLL rearrangements, continue to have poor outcome, despite treatment intensification including allogeneic hematopoietic cell transplantation. Relapsed ALL is a leading cause of mortality in pediatric cancer. Recent advances in immunotherapy targeting the CD19 of the ALL blast have shown remarkable efficacy in some of these relapsed and refractory patients. With improved survival, much of the current focus is on decreasing the long-term toxicities of treatment.

The goal of this study was to investigate the behavior of sows and their piglets reared using the non-all-in all-out system and the all-in all-out system during a 3-week lactation period. The 24 Landrace${\times}$Yorkshire sows (range of parity: 2 to 4) and their litters (range of litter size: 8 to 13 piglets) for each treatment (8 sows/replication) were used in this experiment. The sows were housed in farrowing crates ($0.6{\times}2.1m$) located in pens ($2.4{\times}1.8m$) with totally perforated metal flooring. The crates were kept in an experimental room that was thermostatically controlled to approximately $23^{\circ}C$. A 250-W infrared heat lamp was turned on above the creep area during lactation. The sows and piglets were conventionally managed. The animals were recorded during a 24-h period at 1, 4, 7, 14 and 21 days postpartum. The videotapes were scanned every minute to obtain an instantaneous behavioral sample. In the behaviors of sows, lateral recumbency decreased and ventral recumbency increased from 1 day postpartum to 21 days postpartum. In comparison to the AIAOS, sows in the NAIAOS spent much less time on lateral recumbency (p<0.01), whereas they spent much more time on ventral recumbency and sitting at 4 days postpartum (p<0.05 and p<0.05). In the behaviors of piglets, lying increased and unsuccessful suckling decreased until 21 days postpartum. Compared to the AIAOS at 4 days postpartum, piglets in the NAIAOS spent less time lying (p<0.01), whereas they spent much more time walking and unsuccessful suckling (p<0.01 and p<0.05). These results suggest that the all-in all-out system may be preferable to the non-all-in all-out system for promoting welfare.

방송은 상호연결망에서 사용되는 가장 기본적인 정보전달 기법으로 크게 일-대-다 방송과 다-대-다 방송으로 나눌 수 있다. 일-대-다 방송은 메시지를 갖고 있는 한 노드에서 다른 모든 노드로 메시지를 전송하는 것이고, 다-대-다 방송은 메시지를 갖고 있는 각각의 노드들이 다른 모든 노드들로 메시지를 전송하는 것이다. 그리고 단위 시간 당 전송 포트를 사용하는 방법에 따라 단일 포트 통신 방식(SLA)과 멀티 포트 통신 방식(MLA)으로 나눌 수 있다. 단일 포트 통신 방식은 단위 시간에 메시지를 가지고 있는 노드가 이웃한 다른 하나의 노드로만 메시지를 전송하는 것이고, 멀티 포트 통신 방식은 단위 시간에 메시지를 가지고 있는 노드가 이웃한 모든 노드로 메시지를 전송하는 것이다. 매트릭스 하이퍼큐브는 하이퍼큐브와 동일한 노드 개수를 가지면서 하이퍼큐브보다 망비용이 개선된 연결망이다. 본 논문에서는 매트릭스 하이퍼큐브의 방송 기법을 분석한다. 먼저 매트릭스 하이퍼큐브에서의 일-대-다 방송 알고리즘과 다-대-다 방송 알고리즘을 제안한다. 그리고 SLA 기법을 이용한 일-대-다 방송 시간이 2n+1임과 MLA 기법을 이용한 일-대-다 방송 시간이 $2{\lceil}{\frac{n}{2}}{\rceil}+1$임을 보인다. 또한 SLA 기법을 이용한 다-대-다 방송 시간이 $5{\times}2^{\frac{n}{2}}-2$(n=짝수), $5{\times}2^{\frac{n-1}{2}}+2$(n=홀수)임을 증명한다.

Pythium ultimum에 의하여 발생하는 오이 모잘록병의 생물학적 방제의 효율을 연구하기 위하여 여러 미생물 제제인 Trichoderma harzianum, Streptomyces sp., Bacillus sp.,(그린바이오텍, 경기도 파주)에 톱밥, 쌀겨 등이 첨가되었다. 감자한천배지에 첨가한 톱밥 자체만으로도 P. ultimum 균사의 생육이 저해되었다. Green-all T(Trichoderma harzianum), Green-all S(Streptomyces), Green-all G(Bacillus)제제들은 오이 모잘록병의 발생을 현저히 감소시켰다. 그러나, 종자를 파종하고 병원균을 접종한 실험에 있어서 톱밥, 쌀겨 등을 Green-all T, Green-all S 제제에 첨가한 것은 입모율에 있어서 미생물 제제 단독처리에 비하여 생물학적 방제의 효과가 현저히 증가하지는 못하였다. 대조적으로, Green-all G 제제는 아미노닥터를 첨가하여 주면, 단독 처리시의 42% 이병율에서 2% 이병율로 크게 감소하여, 오이모잘록병에 대한 오이묘에 대한 생물학적 방제효과 실험에서 Green-all T 제제에 톱밥을 첨가하면, 발병도(disease index)가 56으로 5로 감소하여, P. ultimum의 생물학적 방제 효과가 톱밥이 첨가되지 않는 것에 비하여 더욱 증가되었다. 이는 유기물 첨가에 의하여 생물하걱 방제 효과가 증진될 수 있음을 가르쳐 주는 것이라 하겠다.

Background: Public use National Health and Nutrition Examination Survey (NHANES III) and NHANES III linked mortality data were here applied to investigate the association between health insurance coverage and all cause and all cancer mortality in adults. Patients and Methods: NHANES III household adult, laboratory and mortality data were merged. Only patients examined in the mobile examination center (MEC) were included in this study. The sampling weight employed was WTPFEX6, SDPPSU6 being used for the probability sampling unit and SDPSTRA6 to designate the strata for the survey analysis. All cause and all cancer mortalities were used as binary outcomes. The effect of health insurance coverage status on all cause and all cancer mortalities were analyzed with potential socioeconomic, behavioral and health status confounders. Results: There were 2398 sample persons included in this study. The mean age was 40 years and the mean (S.E.) follow up was 171.85 (3.12) person months from the MEC examination. For all cause mortality, the odds ratios (significant p-values) of the covariates were: age, 1.0095 (0.000); no health insurance coverage (using subjects with health insurance), 1.71 (0.092); black race (using non-Hispanic white subjects as the reference group) 1.43, (0.083); Mexican-Americans, 0.60 (0.089); DMPPIR, 0.82, (0.000); and drinking hard liquor, 1.014 (0.007). For all cancer mortality, the odds ratio (significant p-values) of the covariates were: age, 1.0072 (0.00); no health insurance coverage, using with health coverage as the reference group, 2.91 (0.002); black race, using non-Hispanic whites as the reference group, 1.64 (0.047); Mexican Americans, 0.33 (0.008) and smoking, 1.017 (0.118). Conclusion: There was a 70% increase in risk of all cause death and almost 300% of all cancer death for people without any health insurance coverage.

Homogeneous human deoxycytidine kinase was purified in one step from a variety of spontaneous human leukemic cells (T-ALL, B-ALL, B-CLL, AML, CML), and from cultured T-lymphoblast cells (MOLT-4) using the newly developed affinity medium, $dCp_4$-Sepharose. Starting with an ammonium sulfate fraction, purification was achieved in one step with the kinase being eluted from a column by the end product inhibitor, dCTP. The purified deoxycytidine kinase from T-ALL cells phosphorylated deoxyadenosine and deoxyguanosine, as well as deoxycytidine. The enzyme purified from T-ALL and B-CLL cells yielded one major band with a molecular weight of 52 kDa determined by SDS-polyacrylamide gel electrophoresis. AML and CML cells yielded one 52 kDa band and an extra band of 30 kDa molecular weight. On the other hand, B-ALL and MOLT-4 cells showed a low molecular weight band of 30 kDa only. However, the electrophoretic mobilities of enzymatic activity in 12% non-denaturing gels were identical for the dCyd kinase from all different kinds of leukemic cell lines, except that the B-ALL, B-CLL, and MOLT-4 cell preparations had an extra minor peak, all at the same position. dAdo and dCyd phosphorylating activities comigrated indicating that these activities are all associated with the same protein. Two new methods, a disk implantation method and a nitrocellulose powder method were used with a small amount of enzyme protein to raise polyclonal antibodies against dCyd kinase purified from T-ALL cells.

Aim: This study employed public use National Health and Nutrition Examination Survey (NHANES III) data to investigate the association between urinary cadmium (UDPSI) and all cause, all cancer and prostate cancer mortalities in men. Patients and Methods: NHANES III household adult, laboratory and mortality data were merged. The sampling weight used was WTPFEX6, with SDPPSU6 applied for the probability sampling unit and SDPSTRA6 to designate the strata for the survey analysis. Results: For prostate cancer death, the significant univariates were UDPSI, age, weight, and drinking. Under multivariate logistic regression, the significant covariates were age and weight. For all cause mortality in men, the significant covariates were UDPSI, age, and poverty income ratio. For all cancer mortality in men, the significant covariates were UDPSI, age, black and Mexican race. Conclusions: UDPSI was a predictor of all cause and all cancer mortalities in men as well as prostate cancer mortality.
