The study aims at verifying the effects of private donors' emotional or demonstrable utility on their mental health with the mediation effect of self-acceptance and the moderation effect of the gratitude for their lives. As a result of causal analysis of the variables by structural equation models, the notable findings are as follows: First, among the group of private donors with increased gratitude for their lives through sponsorship, while emotional utility from donative activity has a positive effect on donor's mental health, demonstrable utility does not have it. The indirect effect of self-acceptance is proved between emotional or demonstrable utilities and mental health. Second, among the donors without increased the gratitude, emotional utility has direct effect on donor's metal health but demonstrable utility does not affect the metal health. While the self-acceptance shows a full mediation effect between demonstrable utility and mental health, emotional utility has no mediation effect. In conclusion, the moderating effect of the gratitude for their lives is empirically proved and the donors who their gratitude for life has increased due to donative activity show better metal health, self-acceptance level, higher emotional and demonstrable utility, therefore, the gratitude for life is a key for metal health through donation.

Sixty Four fresh and 142 frozen embryos of dairy cattle were transferred to synchronized dairy, beef or Korean Native Cattle nonsurgically at National Animal Breeding Institute from 1985 to 1990. The results obtained were as follows ; 1. The pregnancy rate of fresh embryos(39.1%) was higher than that of frozen embryos(32.4%) and average pregnancy rate was 34.5%. 2. The pregnancy rate of grade 1 embryos was higher than that of grade 2 embryos for both fresh(41.3% vs 33.3%) and frozen embryos(35.4% vs 25.6%). 3. The pregnancy rate according to development stage of fresh embryos was increased with maturity as 29.2%, 33.3%, 50.0% and 54.5% for morula, early blastocyst, blastocyst and expanded blastocyst, respectively. For frozen embryos, the pregnancy rate of blastocyst(44.4%) was higher than those of morula(31.3%) and early blastocyst(28.0%). 4. The pregnancy rate according go recipient-donor synchrony for fresh embryos was higher when the recipients exhibited estrus 1 day earlier than the donors(43.8%) than when the recipients exhibited estrus 1 day later than the donors(38.1%) or when the recipients and donors exhibited estrus at the same time(37.0%). For forzen embryos, the pregnancy rate was decreased when the recipients and donors exhibited estrus at the same time(37.9%), when the recipients exhibited estrus 1 day later than the donors(32.0%) and when the recipients exhibited estrus 1 day earlier than the donors(23.5%), in sequence. 5. The pregnancy rate of heifers was higher than that of cows for both fresh(50.5% vs 37.9%) and frozen embryos(39.7% vs 25.7%). 6. The pregnancy rate according to recipient breed for fresh embryos was higher in dairy cattle(42.1%) and beef cattle(40.%) than in Korean Native Cattle(33.3%). For frozen embryos, the pregnancy rate was decreased beef cattle(39.1%), dairy cattle(30.3%) and Korean Native Cattle(14.3%), in sequence. 7. The pregnancy rate according to equilibrium steps of glycerol and freezing rate was higher when transferred after 3-steps equilibrium and freezing by the rate of $0.3^{\circ}C$/min from $-6^{\circ}C$ to $-35^{\circ}C$ and $0.1^{\circ}C$/min to $-38^{\circ}C$(39.4%) than when transferred after 6-steps equilibrium and freezing by the rate of $0.5^{\circ}C/min$ from $-6^{\circ}C$ to $-30^{\circ}C$(30.3%).

Stereochemical course of the reductive decyanation of two stereoisomeric 4-t-butyl-1-phenylcyclohexanecarbonitriles 3 and 4 using solvated electron has been studied. While sodium-mediated reactions of both 3 and 4 in the presence of alcohols give the same ratio, 1.5 : 1, in favor of the thermodynamically more stable product 5 over the other one 6, the ratios obtained from the potassium-mediated process are found to be very sensitive to the kind of H-donors. When reactions are performed without H-donors, 5 is only obtained from the experiments with both stereoisomers irrespective of the metal species.

Embryo transfer (ET) could be a relevant tool for genetic improvement programs in horses similar to those already underway in other species and produce multiple foals from the same mare in one breeding season. However, there have been no reports describing equine embryo transfer performed in Korea. In the present study, we performed an equine embryo collection and transfer procedure for the first time. We examined the embryo collection and pregnancy, size of embryo during the incubation period after collection, and progesterone (P4) and estradiol-$17{\beta}$ (E2) concentrations in mare's serum at embryo collection and transfer. A total of 16 donors responded to estrus synchronization; estrus was induced in 12 donors and 4 recipients, and artificial insemination was successful in 10 donors and six blastocysts were collected from donors. Of these blastocysts, we monitored the size of blastocysts for 3 day during incubation and transferred 2 blastocysts to a recipient, with 1 successful pregnancy and foal achieved. The dimensions of equine embryo at day 7 to day 9 were $409{\mu}m$, $814{\mu}m$ and $1,200{\mu}m$. The serum P4 and E2 concentrations were $7.91{\pm}0.37ng/{\mu}L$ and $45.45{\pm}12.65ng/{\mu}L$ in the donor mare, and 1$6.06{\pm}3.27ng/{\mu}L$ and $49.13{\pm}10.09ng/{\mu}L$ in the recipient mare.

The purpose of this study was to develop a clinical pathway for the allogeneic bone marrow transplantation donor. For this study, a conceptual framework was developed through a review of the literature including six steps which are using in Jones Hopkins Hospital. USA. The researcher reviewed 129 medical re-cords of donor who had bone marrow donation between January 2002 to January 2004, to identify the overall service contents required by these patients and to make a preliminary clinical pathway. A content validity test was done for the preliminary clinical pathway, a professional group screened 51 medical re-cords and adopted with 3 hospitalization days as the clinical pathway framework. In the fifth step, clinical pathway test was also done to 7 donors from April 28th to July, 2004. After these processes the final clinical pathway was developed. The results of this study are as follows: 1. The vertical axis of the clinical pathway Includes the following 9 items: vital signs, nursing assessment, activity, diet, intervention, medication, test, consultation and patient teaching. The duration of the horizontal axis was 3days from admission to discharge 2. Analysis of the 129 medical records indicated that the average length of stay was 3 4 days. The medical performance according to the vertical axis in the preliminary clinical pathway consisted of 51 items After clinical validity test, it steel consisted of 51 items in the final form. 3. Clinical Validity test was done to 7 bone marrow donors. During these process, The first patient was deleted because he was out of the criteria the investigate set and 6 patients were used, finally The result of this study indicated all of 7 donors were discharged on expected day. 4. Clinical pathway enables to improve the quality of care, multidisciplinary team work It also helps nursing bone marrow donor, effective education to donor or medical member. The results of this study suggest that clinical pathway may be able to improve the quality of nursing care for bone marrow transplantation donors.

Severe aplastic anemia (SAA) is a life-threatening disorder for which allogeneic hematopoietic stem cell transplantation (HSCT) is the current available curative treatment. HSCT from matched sibling donors (MSDs) is the preferred therapy for children with acquired SAA. For patients who lack MSDs, immunosuppressive therapy (IST) is widely accepted as a first-line treatment before considering HCT from an unrelated donor (URD). Given the recent progress in HSCT using URDs for childhood SAA, well-matched URDs became a realistic alternative for pediatric patients who have no suitable related donors and who are refractory to IST. However, it is quite challenging to treat patients with refractory SAA who lack suitable related or URDs. Even though haploidentical HSCT from genetically mismatched family members seemed to be an attractive procedure with the amazing benefit of readily available donors for most patients, early attempts were disappointing because of refractory graft-versus-host disease (GVHD) and excessively high transplant-related mortality. Recent advances with effective ex vivo depletion of T cells or unmanipulated in vivo regulation of T cells, better supportive care, and optimal conditioning regimens have significantly improved the outcome of haploidentical transplant. Besides considerable progress in the treatment of malignant diseases, recent emerging evidences for haploidentical HSCT in SAA has provided additional therapeutic options for patients with refractory diseases. Further improvements to decrease the rates of graft failure, GVHD, and infectious complications will facilitate the emergence of haploidentical HSCT as a front-line therapy for treating acquired SAA in children and adolescents who have no suitably matched donors.

Three-dimensional computed tomography is an effective tool to estimate the liver volume of living donors for the live liver transplantation. When additional operation is required, magnetic resonance imaging is conducted to determine the safety of the donor. This study compared the accuracy of magnetic resonance imaging and computed tomography in estimating 3D liver volume of 23 male and 7 female donors who underwent both magnetic resonance imaging and computed tomography tests before the transplantation. The analysis was conducted to see whether the liver's estimated total volumes and the left lobe volumes obtained from 3D-magnetic resonance imaging and 3D-computed tomography were identical. Volumes of the right lobe estimated with 3D-magnetic resonance imaging and 3D-computed tomography were compared with the actual volume of the right lobe harvested in the operating room because the volume of the right lobe is an important determinant in the safety of the donor. The total volume of the liver estimated from 3D-magnetic resonance imaging and 3D-computed tomography differed (1238.1904 units and 1402.364 units respectively). The left lobe volume of the liver estimated with 3D-magnetic resonance imaging and 3D-computed tomography also differed (450.530 units and 554.490 units, respectively). The right lobe volume of the liver estimated with 3D-magnetic resonance imaging and 3D-computed tomography were 787.660 units and 847.545 units, respectively, while the actual average right lobe volume of the harvested liver was 678.636 units. 3D-computed tomography has been widely used to estimate the right lobe volume of the donors' liver. However, 3D-magnetic resonance imaging was also very effective in estimating the volume of the liver. Thus, 3D-magnetic resonance imaging is also expected to become an important tool in determining the safety of the donors before transplantation.

Hepatitis C is an ailment of liver caused by hepatitis C virus (HCV) infection. About 3% of the world population is infected by this virus. HCV infection is a leading reason for liver cirrhosis and therefore a major source of hepatocellular carcinoma. The study focused on the incidence of active HCV infection in blood donors of Mardan district of KPK, Pakistan. A total of 5318 blood donors were inspected for the presence of anti-HCV antibodies and HCV-RNA using ICT (immune-chromatographic test), ELISA and RT-PCR at Mardan Medical Complex (MMC), Mardan. Out of these, 157 (2.95%) were positive by ICT, 60 (1.12%) by ELISA and 56 (1.05%) for HCV-RNA. The frequency of active HCV infectivity amongst the blood donors from district Mardan, KPK Pakistan was 1.05 %. Application of strict measures during blood donor selection and use of proper screening assays such as ELISA in place of ICT devices can give a more accurate picture so that the incidence of this viral infection in HCV negative blood recipients can be reduced.
