  • 관계형 데이터베이스 시스템의 기능이 점차 확대되면서 사용자 정의 함수의 역할이 다양하게 되었다. 이에 따라 사용자 정의 함수의 수행 속도뿐 아니라 데이터베이스 시스템의 안정성과 보안의 중요성이 부각되었다. 사용자 정의함수 지원방식은 크게 3가지로 나눌 수 있다. : 정적로딩 방식, 공유 라이브러리 방식, 프로세스 호출 방식, 기존의 데이터베이스 시스템에서 사용되는 공유 라이브러리 방식은 속도면에서 우수하나 안정성, 보안에 대한 요구를 만족시키지 못하며 시스템에 이식할 때 문제가 있다. 우리는 프로세스 호출 방식을 개선하여 사용자 정의 함수지원을 구현하였다. 본 논문에서는 관계형 데이터베이스시스템에서 사용하는 사용자 정의함수를 구현하는데 있어서 고려해야할 점들을 살펴보고 성능을 측정한다. 성능 평가를 통해 우리가 구현한 방식이 공유 라이브러리방식과 성능차이는 적은 반면 장점이 많다는 것을 보인다.

  • 거대세포바이러스(Cytomegalovirus; CMV) 감염은 동종조혈모세포이식 환자의 주요 사망원인 중 하나이다. 용량감소전처치(Reduced-intensity conditioning; RIC)를 이용한 조혈모세포이식은 골수억제전처치(Myeloablative conditioning; MAC)에 비해 골수억제 및 면역억제가 적으므로 CMV 감염 발생율을 감소시킬 것이라 예상되었으나 예방적 면역억제요법, T세포 제거 약제의 사용 등으로 서로 상이한 결과가 보고되고 있다. 2007년 1월부터 2009년 12월까지 총 141명의 환자(MAC 113명, RIC 28명)가 동종조혈모세포이식을 받았으며, CMV 감염은 MAC 62.8%, RIC 57.1% (p = 0.310), CMV 질환은 각각 12.4%, 14.3% (p = 0.785)에서 발생하였다. CMV 감염/질환 발생빈도와 CMV 항원 혈증검사 지속기간, 초기/최고치, 생존율은 두 군간 유의한 차이가 없었다. CMV 감염 위험인자에 대한 다변량분석 결과, 환자가 고령일수록(HR 1.024, 95% CI 1.002-1.045; p = 0.031) 또는 grade 2 이상의 급성 이식편대숙주병이 발생한 경우에(HR 1.849, 95% CI 1.031-3.315; p=0.039) CMV 감염 발생 위험율이 유의하게 높았다. 결론적으로, 전처치요법 강도에 따른 CMV 감염의 발생빈도와 발현양상의 차이는 없었으나, 고령이거나 grade 2 이상의 급성 이식편대숙주병이 발생한 환자의 경우 CMV 감염 발생과 유의한 연관성을 보였다. 이상과 같은 결과에 비춰 봐서 CMV 질환이 대부분 이식 100일 이후에 발생한 점을 고려할 때, 이식 후 CMV 감염 발생 시 ganciclovir 선제요법과 함께 이들 환자들에게 지속적인 모니터링을 실시하는 것이 필요할 것으로 사료된다.

  • This experiment was carried out to investigation the growth differentiation between direct sowing and transplanting on P. ginseng cultivated on field and underwood. The results were as follows: In direct sowing treatment, emergence rate of P. ginseng cultivated on field and under conifer forest was above 80%, but it was only 40% at cultivated under broad-leaved forest. And survival rate was directly diminished about 10% every year. In transplanting treatment, survival rate was also diminished every year, it was slighter than that of direct sowing treatment. The growth amount of P. ginseng cultivated underwood was poor, compared to field culture, but there was no significant between conifer forest and broad-leaved forest. In transplanting treatment of 1 to 6 year-root seedling, survival rate of P. ginseng cultivated underwood was equal or slightly good compared to that of cultivated on field. Among seedling age, survival rate of elder seedling was lower than that of younger seedling. In P. ginseng cultivated underwood, the annual growth increment of 1 and 2 year-root seedling increased slowly and continually, whereas, that of 3 to 6 year-root seedling stopped or decreased slightly.

  • The purpose of this study was to examine changes in the accuracy and range of produced pitch in children with cochlear implants (CI) after an interval-based singing program. A total of three children with CIs aged 5 received twelve 35-minute individual sessions two to three times per week. The interval-based singing program was composed with third, fifth, and eighth intervals and implemented pitch discrimination, pitch imitation, and singing songs with target intervals in a sequence. At pretest and posttest, the changes in accuracy of pitch production during pitch imitation and singing were measured. The results demonstrated that all participants showed improvement in pitch accuracy and produced the target notes with great similarity to the expected pitches in the original song. The range of produced pitch also increased after the program. The results indicate that sequential trials to imitate pitches in a multisensory environment to facilitate the processing of pitch information may reflect how this population perceives pitch information and assist children with CIs to improve their pitch accuracy.

  • Immatured bovine follicular oocytes added with serum, hormones, granulosa cells and bovine oviduct epithelium cells were fertilized in vitro after in vitro maturation. In vitro maturation and early development capacity were examined and IVF-derived embryos were transferred and to recipients and effects of sperm treatment on in vitro capacitation were investigated. The rate of in vitro maturation was improved when they were co-culutred with granulosa cells in the TCM199 medium added with 10% FCS and hormones. The percentage of acrosome reaction was not differed between sperm treatments and sperm of above 25% under-went AR during 30 min preincubation with caffeine and heparin. The cleavage rate of oocytes in vitro fertilized in TCM199 medium added with 10% FCS and hormones, GC or BOEG higher than that in medium with 10% FCS and GC. But the rate was not significantly different between GC and BOEG The cleavage of rate oocytes cultured in medium containing serum, hormones and BOEG was 80.2% and more embryos were developed to Blastocyst (17.3%). The selected embryos were transferred to 9 recipients by surgical or nonsurgical method but did not result in pregnancy.

  • A 49-year-old female patient who had obstruction of superior vents cave(SVC) with SVC syndrome was successfully managed by bypass operation of superior vents cava with spiral vein graft. A composite spiral vein graft was placed between the right innominate vein and the right atrium to bypass the occluded SVC. The graft was constructed from the patient's own saphenous vein, which was split longitudinally and wrapped around a stent in spiral fashion and the edges of the vein were sutured together to form a large autogenous conduit. The patient was relieved o SVC obstructive symtoms and signs and discharged 21 days postoperatively without any complication.

  • These studies were conducted to investigate the effect of repreated superovulation on embryo production, the effect of the frozen-thawed embryos transferred on the developmental stage and grade, and donor-recipient synchrony on pregnancy rate in Korean native cattle. The results obtained in these studies were as follows: 1. Repeated superovulations in Korean Native Catile were not affected on the number of corpus luteum (CL), embryos recovered and embryos cleaved (range: 4.8 $\pm$ 4.21 to 9.5 $\pm$ 6.50, 1.8 $\pm$ 2.53 to 8.2 $\pm$ 8.04 and 1.6 $\pm$ 2.32 to 4.0 $\pm$ 4.59, respectively). 2. Blastocyst embryos (38.5%) showed higher pregnancy rate than morula (31.6%). 3. The pregnancyrates of cattle transferred with good and fair embryos were 33.3% and 40.4%, respectively. 4. The pregnancy rate when the donors exhibited estrus 12 hours earlier than the recipients (62.5%) was higher than when the donors and recipients exhibited estrus at the same time (33.3%) or when the donors exhibited estrus 12 hours later than the recipients (20.0%).

  • The development potential of bovine somatic cells was evaluated using nuclear transfer. A single donor cell derived from fetus of HanWoo(Korean Native Cattle) was selected and deposited into perivitelline space of each enucleated oocyte before electrical fusion and activation. Nuclei of donor cells starved for 7 days (37%) tended to support the development of reconstitute embryo the blastocyst stage better than those of donor cells starved 3, 14 and 30 days. The cleavage rate was significantly lower(P<0.05) in reconstitute embryos derived from large size donor cells(51.2%), than those from small medium size donor cells(76.6 and 73.5, respectively). The developmental rate to blastocyst of reconstructed embryos from medium size donor cells was higher than those from small and medium size donor cells. This study demonstrates that an appropriate culture period for induction into quiescent stage and the size of donor cells effect on the efficiency of nuclear transfer using cultured bovine cells.
