Purpose: This study was performed to identify the pre-and post-transplant nutritional assessment for patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Methods: The subjects of this study were 25 patients undergoing allogeneic HSCT. The data collection was performed from January 31st to March 31st, 2011. The Patient-Generated Subjective Global Assessment (PG-SGA), anthropometrics and biochemical test were collected from the time they entered the isolation unit until they left. Results: Pre-transplant nutritional assessment status indicated moderate malnutrition which scored $7.32{\pm}1.68$ in PG-SGA. There were 22 patients (88.0%) with moderate malnutrition and 3 patients (12.0%) with severe malnutrition. Post-transplant nutritional assessment indicated severe malnutrition status which scored $11.92{\pm}3.26$ in PG-SGA. Pre-and post-transplant nutritional assessment displayed significant differences (p<.001) in PG-SGA score. Hematopoietic stem cell transplantation led to a deterioration of patients' nutritional status. Pre-transplant patients were already in malnutrition status and patients undergoing allogeneic HSCT were at risk for malnutrition. Conclusion: Pre-and post-transplant patients were categorized as having undernutritional and malnutritional status. Pre-transplant nutrition status impacted on post-transplant nutritional status. Health care personnel should pay attention to patient's nutrition status when undergoing allogeneic HSCT with appropriate nutritional assessment tools.

Purpose: To examine the relationships between self-care, social support, and biological markers in liver transplant recipients. Methods: The participants included 118 liver transplant recipients who visited outpatient clinic at Y University Hospital in Seoul from April to May, 2013. Questionnaires consisted of self-care and social support scales. The biological markers were collected by reviewing electronic medical records. Data were analyzed with descriptive statistics, t-test, ANOVA with Scheff$\acute{e}$ post-hoc test, and Pearson's correlation. Results: The self-care score was significantly higher in a patient group within 6 months post-transplant when compared to a patient group post-transplant 3 to 5 years (F=3.10, p=.018). The self-care showed positive correlation with social support with statistical significance (r=.36, p<.001). Conclusion: As the self-care in liver transplant recipients had a positive correlation with social support from family and healthcare providers, the development of comprehensive long-term nursing intervention systems including counseling, education, and support in consideration of progress of time period after transplantation is necessary to enhance self-care behaviors among this population.

In this study, we examined the impact of transplant timing of mother plants for seedling strawberry on growth and development of daughter plants and field stage. The leaf growth of treated mother plants and crown thickness were low when transplant was performed on April $10^{th}$. Based on the results collected until July $13^{th}$, the numbers of daughter plants with more than two leaves were 20.6 and 19.5 for March $10^{th}$ and March $25^{th}$, and these values decreased by April $10^{th}$ and April $25^{th}$ showing values of 15.1 and 11.8, respectively. After seedling growth was complete, leaf area and fresh weight of the saplings were remarkably low beginning from the transplant on April $10^{th}$. Crown thickness of saplings was generally lower when transplant timing was late. After 45 days of transplant leaf length and width were noticeably lower than the transplant on April $10^{th}$ and $25^{th}$. First cluster was 100% for both the March $10^{th}$ and $25^{th}$ transplant, followed April 10th and $25^{th}$ with values of 66% and 43%. The results revealed that transplant on March $10^{th}$ and $25^{th}$ had a greater positive impact on the growth and development of the strawberry cultivar 'Seolhyang'. A supplementary study will have to be conducted to determine the relationship between the harvest period of the first cluster and the yield of marketable strawberries depending on the transplanting time of mother plants.

This study was conducted to investigate the effect of S-phase synthronized nuclear transfer on the development of nuclear transplant bovine embryos. A blastomere derived from the 16~32 cell stage bovine embryos was transferred into an enucleated metaphase II(MII) oocytes or activated S-phase eggs. From the MII-phase and S-phase nuclear transfer, 6.3%(4/63) and 13.8%(9/65) of nuclear transplant embryos developed to the blastocyst stage, respectively. In the S-phase nuclear transfer, maximal proportion of embryos developed to the blastocyst stage(16.6%) was obtained after the recipient cell was activated 8 h prior to receving a donor nucleus. MII-phase nuclear transplant embryos showed the PCC state of their nuclear at 1.5~2 h after fusion, whereas, S-phase nuclear transplant embryos did not undergo PCC. The result of this study suggests that if blastomeres of unknown cell-cycle-stage are used, S-phase nuclear transplantation through the activation of enucleated oocytes prior to fusion enhances development of nuclear transplant embryos. This result also suggests that the interval time from oocyte activation to cell fusion may affect the development of nuclear transplant embryos.

The purpose of this study was to explore the educational needs of kidney transplant patients and educational importance perceived by their nurses to develop a rehabilitational and educational program. Data were collected from January 29, 1999 to July 30, 1999 with interviews using a structured questionnaire. The subjects for this study were 173, of whom 107 were patients who had had a kidney transplant and had visited the out-patient department and 66 were transplant ward nurses who were taking care of the kidney transplant patients at six general hospitals located in Seoul. The questionnaire used for this study was developed by the investigator through a literature review and collected and modified by 11 professional personnel and 3 kidney transplant patients. The data were analyzed using the SAS program for numbers, percentiles, mean, standard deviation, t-test, ANOVA, and $Scheff{\acute{e}}$ test. The results were as follows; 1) In the patient group, the total mean score for educational needs was 154.61 and the item mean score was 3.96. In the nurses group, the total mean score for perceived educational importance was 166.26 and the item mean score was 4.26. In the nurses group, perceived educational needs were scored higher than by the patient group. With regard to domains, both patient and nurses group had the highest educational needs and perceived educational importance in the domain of physical condition and the top five items in the educational needs and perceived educational importance were also in the domain of physical condition. 2) In the patient group, women and the divorce/bereavement group had higher educational needs in the domain of nutritional management, those who had been admitted longer than 4 weeks from their kidney transplant time had higher educational needs in the domains of physical condition and those who were less than 4 years from their transplant had higher educational needs in the domain of follow-up care. In the nurses group, those who were married had higher perceived educational importance in the domain of physical condition.

Purpose: The aim of this study was to compare the levels of anxiety, depression, and quality of life (QOL) among kidney or liver transplant candidates and recipients. Methods: A cross-sectional descriptive design was utilized. The 160 subjects were recruited and assigned to three different conditions: awaiting transplant group; post-transplantation (TPL) group within less than one year of surgery; and post-TPL group with one year and no more than two years post surgery. The levels of anxiety and depression were measured by the Hospital Anxiety and Depression Scale. The level of quality of life was measured by the Medical Outcomes Study Short Form-36 version 2. Results: The anxiety score was significantly higher in the waiting group compared with the 1~2 years post TPL group. The depression score was significantly higher in the waiting group compared with the post TPL groups. The QOL was significantly lower in the waiting group compared with the post TPL groups. Conclusion: Our results show a high prevalence of anxiety and depression and a marked reduction in the QOL in transplant candidates compared to the recipients. This study indicates that the group waiting for transplants may have unmet needs during that time period. Health professionals should be encouraged to attend to the psychological distress of the transplant candidates in order to improve their quality of life.

Purpose: This study aimed to investigate the effects of postural control exercise on the delayed heart rate increase in heart transplant patients. Methods: The subject was a female heart transplant recipient who had a delayed increase in heart rate during exercise. The intensity of exercise was performed at MBorg level 4. The A-B-A' and A-B-A'-B' designs were used to identify the changes in heart rate during active-assisted exercise, lower limb postural control exercise, and upper limb postural control exercise. Experiments were performed for four weeks. The heart rates at pre- and post-exercise were compared, and the time to reach MBorg 4 was measured. Results: In the active-assisted exercise, the average heart rates at pre- and post-exercise and after 10 min of exercise were 88, 89, and 87.7 bpm, respectively. In the repetitive comparison of pre- and post-exercise in the lower limb postural control exercise, the difference in the mean heart rate was 3.5 and 3 bpm in stable support and 14 and 14.5 bpm in unstable support, respectively. In the repetitive comparison of pre- and post-exercise in the upper limb postural control exercise, the difference in the mean heart rate was 6 and 4 bpm in stable support and 4 and 4.5 bpm in unstable support. The time required to reach MBorg 4 was short when both the upper and lower postural control exercises were performed in an unstable state. Conclusion: We suggest that combining proper postural control exercise with strength exercise and aerobic exercise, among others, may be effective in rehabilitating patients in the recovery stage after a heart transplant.

This study was to determine the effect of ionomycin and 6-dimethylaminopurine (6-DMAP) and/or elcetrical stimulation on the oocyte activation and production of rabbit nuclear transplant embryos. The oocytes were collected from the oviduct of superovulated rabbits at 14 h post hCG injection and cultured in TCM-199 containing 10% FBS until 19 h post hCG injection. To determine the optimum concentration and exposure time of 6-DMAP, some oocytes were activated with 5 $\mu$M ionomycin for 5 min and then in 2.0 mM 6-DMAP for 0.5 to 3.0 h, or in 1.0 to 3.0 mM 6-DMAP for 2.0 h. Other control oocytes were stimulated electrically(3X, 1.25 kV/cm, 60 $\mu$sec) in 0.3 M mannitol solution supplemented with 100 $\mu$M CaCl$_2$ and MgCl$_2$. The nuclear donor embryos of 8-cell stage were synchronized to G$_1$ phase of 16-cell stage, and the recipient cytoplasms were obtained from removal of the first polar body and a portion of membrane bound cytoplasm of the oocytes collected at 15 h post hCG injection. A separated blastomere was injected into the perivitelline space of the enucleated oocytes. The oocytes injected with nucleus were cultured until 19 h post hCG and then electrofused and activated by electrical stimulation with or without ionomycin and 6-DMAP. These nuclear transplant embryos were cultured in TCM-199 containing 10% FBS in 39˚C, 5% CO2 incubator for 120 h. For the oncytes activated parthenogenetically with electrical stimulation with or with-out ionomycin and the various concentration of exposure time of 6-DMAP, the highest cleavage(92.3%) and development to blastocyst stage(41.0%) were resulted from the oocytes activated by ionomycin and 2.0 mM 6-DMAP for 2.0 h, which were found to be significantly(P<0.05) higher than the cleavage(45.2%) and developement to blastocyst stage(14.3%) from the oocytes activated with electrical stimulation. The significantly(P<0.05) more oocytes(71.4%) developed to 4 cell stage at 24 h post activation by ionomycin and 6-DMAP than those by electrical stimulation(18.9%). For the nuclear transplant embryos, the cleavage rate was similarly high in oocyte activation by electrical stimulation with(79.4%) or without ionomycin and 6-DMAP(70.5%). However, the embryo development to blastocyst stage was significantly(P<0.05) higher in oocyte activation by electrical stimulation with ionomycin and 6-DMAP(44.4%) than by electrical stimulation only(25.0%). The significantly(P<0.05) more nuclear transplant embryos(45.6%) developed to 4 cell stage at 18 h post activation by electrical stimulation with ionomycin and 6-DMAP than those by electrical stimulation only(10.6%). These results indicated that the supplemental oocyte activation by ionomycin and 6-DMAP with electrical stimulation enhanced and accelerated the preimplanted in vitro development of the rabbit nuclear transplant embryos.

The purpose of this study is to develop and evaluate the Self Efficacy Promotion and Exercise Program to prevent of obesity and cardiovascular diseases for the kidney transplant recipients. The subjects were selected randomly among the patients who underwent kidney transplantations at one major transplantation hospital in Seoul, Korea. This study ws carried out between November 23, 1999 and February 15, 2000. The subjects in this study consisted of 16 patients who had kidney transplantations between 1 month and 12 months ago prior to this study. They were all on steroids therapy and did not take any physical exercise regularly. The subjects received the self efficacy promotion and exercise program for 12 weeks which contained self efficacy promotion education and exercise program. The weight, body fat rate, exercise time and cardiopulmonary function were evaluated before the experiment and after the experiment. The results were as follows: 1. After the experiment, the weight was significantly decreased than that of before the experiment(p=.0001). 2. After the experiment, the body fat rate was significantly decreased than that of before the experiment(p=.0010). 3. After the experiment, the exercise time was significantly increased than that of before the experiment(p=.0002). 4. After the experiment, the absolute VO2 was significantly increased than that of before the experiment(p=.0008). 5. After the experiment, the relative VO2 was significantly increased than that of before the experiment(p=.0002). This study showed that the self efficacy promotion and exercise program was effective. So it would be expected that this self efficacy promotion and exercise program could be applied as an effective independent nursing intervention widely in prevention of obesity and cardiovascular diseases for kidney transplant recipients.

Purpose: The main purpose of this study was to develop a substantive theory on the life of patients with heart transplantation in the context of Korean society and culture. The question for the study was 'What is the life of patients like with a heart transplant?'. Method: A grounded theory method guided the data collection and analysis. Participants for this study were 12 adults who regularly visited a Cardiovascular ambulatorium in a medical center. The data was collected through an in-depth interview and analyses were performed simultaneously. Result: 'Developing a new life to live on borrowed time' was the core category in this study. It revealed two types of life, one is living in peace and another is thinking positive. Conclusion: This study provides a framework for the development of individualized nursing interventions to care for patients with Heart Transplantation. The findings may provide pointers for health professionals about ways to improve support for heart transplant recipients.
