Renal transplantation is the treatment of choice for children with end-stage renal disease. The outcome of pediatric kidney transplantation has improved dramatically in recent years, with lower acute rejection rates, superior graft survival, and low mortality. These improvements have allowed increased attention to other aspects of care for long-term survivors. Taking this into consideration, this review article will focus on the key issues related to pediatric kidney transplantation such as growth, neurocognitive function, nonadherence, and posttransplantation infectious complications, including lymphoproliferative disease, to broaden the understanding of pediatricians who provide pre-and postoperative care to children with end-stage renal disease.

ABO 부적합성 장기이식은 이미 존재하는 항체에 의한 초급성 및 급성 면역 거부반응 때문에 심장이식을 포함한 대부분의 장기이식에서 금기시 되어왔다. 그러나 ABO 부적합성 장기이식이 혈장교환, 항체흡착술, 면역억제, 비장절제술 등에 의해 성공적으로 치료되었다는 여러 보고가 나오고 있다. 우리는 혈장교환과 면역억제에 의한 ABO 부적합성 심장이식의 성공적인 치료를 경험했다. 그러나 이것이 ABO 부적합성 심장이식술을 정당화하는 것은 아니며, 계속되는 급성면역거부 반응이나 만기거부반응에 대한 ABO 부적합성의 관련이 충분히 알려지지 않았기 때문에 장기 추적검사가 요구된다.

Nuclear transplantation technique is known as the most potential and efficient method for producing a large number of genetically identical animals from a single embryo. The technical development of nuclear transplantation in mammals and its application to the production of cloned animals are described. For the efficient and successful production of cloned embryos by nuclear transplantation, the right selection and micromanipulation of recipient eggs or embryos as capacious recipient cytoplasm, the adequate and benefitlal preparation of multiple totipotent embryonic cells as donor nuclei, and also the fusion technique are very critical. Recent studies approaching to these critical points are introduced and discussed. Up to date, the overall efficiency of production of cloned embryos and offspring in livestock is estimated to be low. Further technical development of nuclear transplantation will enable large-scale production of cloned livestock and in near future the commercial cloning of animals will become a reality.

This paper describes an automatic transplantation machine of optical fiber controlled by PLC. The transplantation operations is a key operation for the optical fiber application products, such as bag, cap, and others. To transplant 200∼500 optical fibers, there are many recurrent manual operation needed with conventional process. In this paper. we propose an automatic machine that reduce transplanting time and enhance product quality. Developed machine includes transplantation, heat cutting and ultraviolet coating operation. Also proposed Machine is controlled by PLC to adjust operation parameters such as pulling length, cycle time, coating time and others. Developed Machine has been applied in the field and found to be a useful system.

Living donor liver transplantation (LDLT) has become an inevitable procedure due a shortage of deceased donors under the influence of religious and native cultures. The most important concern in LDLT is donor safety. This study reviewed the safety of LDLT donors from reported studies of morbidity and mortality. Many studies have reported mortality and morbidity rates ranging from 0% to 33% for healthy liver donors. Use of laparoscopic surgery on LDLT donors has advantages of reduced blood loss, lower postoperative morbidity and shorter hospital stay relative to conventional open surgery. There is a consensus that remnant liver volume (RLV), degree of steatosis, and donor age are the most important factors influencing donor safety. In LDLT, donor hepatectomy can be performed successfully with minimal and easily controlled complications. However, a large-scale prospective cohort study is needed to better understand the risk factors and accurately determine the complication rates for LDLT.

Purpose: This study was designed to create the job description of Korean transplantation nurse practitioner and examine performance frequencies, criticality, and difficulties of task elements. Method: The sample consisted of 63 nurses and coordinators who performed duties related to transplantation at medical center in Korea. A survey method was used, and the questionnaire included frequencies, criticality, and difficulties of task elements in job description by the DACUM method. Using SPSS WIN 10.0, descriptive statistics such as frequency distribution, means, and standard deviations were conducted to examine the subject's general characteristics, the frequencies, criticality, and difficulties of task performance. Result: The job description of transplantation nurse practitioners revealed 5 duties, 22 tasks, and 85 task elements. On the all five duties, the averages of the performance frequency, criticality, and difficulty were 2.41, 3.38, and 2.78, meaning that the respondents rarely perform the 5 duties, but consider them critical and easy to perform. Conclusion: The job description of the transplantation nurse practitioner included duty, task, and task element and definition of job completed. Thus we recommended a data based trial to confirm and validate the information gathered.

Purpose: The purpose of this study was to investigate the physical conditions and social adaptation of children who have undergone hematopoietic stem cell transplantation. Methods: The participants in this descriptive survey were 37 children who had undergone hematopoietic stem cell transplantation at least one year ago. Data were collected through observation and questionnaires and processed with the SAS program. Results: Compared to the time of diagnosis, WBC, RBC and platelet counts had increased significantly. The children were taller than at the transplantation stage, but there was no change in weight and 73% of the children had physical symptoms. Boys who were between 6 to 11 years of age had lower rates of socialization and academic progress than normal Korean boys. Boys between 12 to 17 years of age had higher rates of socialization, but lower rates of academic progress. Girls between 6 to 17 years of age scored lower than normal Korean girls in both categories. Conclusion: The above findings indicate that children who have undergone hematopoietic stem cell transplantation try hard to participate in everyday activities. Therefore nursing interventions to improving normal growth and development and facilitate social adaptation should be provided for them.

The nuclear transplantation technique is known as the most potential and efficient method for producing large numbers of genetically identical animals from a single embryo and somatic cells. After Dolly was introduced in 1997, many scientists were amazed. A possibility came to a reality that live offspring could be produced with differentiated somatic cells from an adult animal. On the other side, many in the press and the sensationalists focused on the socially, ethically and scientifically unacceptable sides of the technology. In this article, the history, current status and prospects of the technological development of nuclear transplantation in mammals and its application to the production of cloned animals are described. For the efficient and successful production of cloned embryos by nuclear transplantation, the right selection, preactivation and micromanipulation of oocytes as capacious recipient cytoplasm, the adequate and benefitial preparation of multiple totipotent embryonic and somatic cells as donor nuclei, fusion of them and in vitro production of cloned embryos are very critical. Recently the overall efficiency of production of cloned embryos and offspring in livestock has been much improved. Cloning will also be a more efficient, faster and useful way of creating transgenic fetuses for gene therapies, gene pharming, organs for xenotransplantation by preselection and mass production of transgenic embryos and consequently improving the production efficiency in transgenic animals. Further technical development of nuclear transplantation will enable large-scale production of cloned livestock and in near future the commercial cloning of animals will become a reality.
