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.

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.

This study was to investigate the effects of electrofusion, activation and developmental stage of donor embryos on in vitro development of nuclear transplant bovine embryos. A single blastomere nucleus from 8-cell to morula stage embryos produced by in vitro fertilization(IVF) was transferred into a recipient oocyte enucleated at 23∼25 h after in vitro maturation(IVM) or into a recipient oocyte enucleated and cultured for 14∼15 h. In one experiment the nuclear transplant embryos were subjected to additional activation treatments. Fusion rate of nuclear transplant eggs was high at direct current(D.C) voltages of 1.0 and 1.5 kV/cm 991.5 and 93.3%, respectively), but decreased at 2.0kV/cm (81.8%). Additional activation treatments by electric pulases or 7% ethanol did not affect the cleavage and development of nuclear transplant embryos. Development of nuclear transplant embryos slightly increased by delayed nuclear transfer and fusion (42∼43 h after IVM). With this system, blastocysts were obtained from transfer of 8-cell to morula stage donor nuclei (9.6%∼2.4%). The result of this study suggests that nucleo-cytoplasmic interactins, expecially activation of ooplast are very important for the development of nuclear transplant embryos, and donor cell stage does not affect the development of nuclear transplant embryos.

Purpose: The study aimed to understand the semantic structure and nature of the disease experience of kidney transplant recipients with kidney graft failure by applying phenomenological research methods. Methods: Data were collected between February and September 2021 through individual in-depth interviews with 12 kidney transplant recipients with kidney graft failure. Colaizzi's phenomenological analysis was used to analyze the meaning of the participants' illness experiences. Results: 5 theme clusters and 15 themes were derived. The five theme clusters are as follows: (1) First transplant giving me a second life; (2) Body and mind becoming sick again; (3) Waiting for a re-transplant with hope and worry; (4) Life supported by gratefulness; (5) Having control over my own life. Conclusion: This study shows that kidney transplant recipients with kidney graft failure experience physical and psychological difficulties during the long disease period and require help from many people, including family members, friends, colleagues, and health care providers, to overcome their difficulties.

Purpose: We investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI). Methods: Between February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38). Results: The incidence of delayed graft function (DFG) was significantly higher in patients with AKI than it was in the non-AKI group (P = 0.008). There were no significant differences among the 4 groups in graft survival (P = 0.074) or patient survival (P = 0.090). However, the long-term allograft survival rate was significantly lower in group IV than it was in other groups (P = 0.024). Conclusion: Allografts from deceased donors with terminal AKI had a higher incidence of DGF than did those from donors without AKI. However, there is no significant difference in graft and patient survival rates among the groups. So, the utilization of renal grafts from ECDs with terminal AKI is a feasible approach to address the critical organ shortage.

Chylomicron retention disease, also known as Anderson's disease, is a rare hereditary hypocholesterolemic disorder, recessive inherited, characterized by nonspecific symptoms as abdominal distension, steatorrhea, and vomiting associated with failure to thrive. We describe a patient with failure to thrive, chronic diarrhea and steatorrhea who the diagnosis of chylomicron retention disease was established after several months of disease progression. The genetic study confirmed a homozygosity mutation in SAR1B gene, identifying a mutation never previous described [c.83_84delTG(p.Leu28Argfs*7)]. With this case report the authors aim to highlight for this very rare cause of failure to thrive and for the importance of an attempting diagnosis, in order to start adequate management with low fat diet supplemented with fat-soluble vitamins, reverting the state of malnutrition and avoiding possible irreversible and desvantating complications.

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 purpose of this study was to construct and test a structural equation model of self-management of liver transplant recipients based on self-determination theory. Methods: Participants were 275 outpatients who received liver transplantation. A structured self-report questionnaire was used to assess health care providers' autonomy support, transplant-related characteristics, illness consequence perception, autonomy, competence, family relatedness, depression and self-management. Collected data were analyzed using SPSS/WIN 24.0 and AMOS 24.0 program. Results: The modified model showed a good fitness with the data: GFI=.96, RMSEA=.06, CFI=.96, NFI=.93, TLI=.93, PGFI=.43, PNFI=.49. The health care providers' autonomy support, competence, family relatedness and depression were factors with a direct influence on the self-management of liver transplant recipients. The health care providers' autonomy support and illness consequence perception had an indirect influence through competence, family relatedness and depression. However, the transplant-related characteristics and autonomy did not have a significant effect on self-management. This model explained 59.4% of the variance in self-management. Conclusion: The result suggests that continuous education must be done to promote the competence of liver transplant recipients and to encourage the patient to positively perceive their current health condition with a view that enhances one's self-management. Additionally, the liver transplant recipients should be screened for depression, which would affect self-management. Most of all, health care providers, who have the most influence on self-management, should improve therapeutic communication and try to form a therapeutic relationship with the liver transplant recipients.

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.
