Purpose: This study compared outcomes in children with acute leukemia who underwent transplantations with umbilical cord blood (UCB), bone marrow, or peripheral blood stem cells from a human leukocyte antigen (HLA)-matched related donor (MRD) or an unrelated donor (URD). Methods: This retrospective study included consecutive acute leukemia patients who underwent their first allogeneic hematopoietic stem cell transplantation (HSCT) at Samsung Medical Center between 2005 and 2010. Patients received stem cells from MRD (n=33), URD (n=46), or UCB (n=41). Results: Neutrophil and platelet recovery were significantly longer after HSCT with UCB than with MRD or URD ($p$ <0.01 for both). In multivariate analysis using the MRD group as a reference, the URD group had a significantly higher risk of grade III to IV acute graft-versus-host disease (GVHD; relative risk [RR], 15.2; 95% confidence interval [CI], 1.2 to 186.2; $p$=0.03) and extensive chronic GVHD (RR, 6.9; 95% CI, 1.9 to 25.2; $p$ <0.01). For all 3 donor types, 5-year event-free survival (EFS) and overall survival were similar. Extensive chronic GVHD was associated with fewer relapses (RR, 0.1; 95% CI, 0.04 to 0.6; $p$ <0.01). Multivariate analysis showed that lower EFS was associated with advanced disease at transplantation (RR, 3.2; 95% CI, 1.3 to 7.8; $p$ <0.01) and total body irradiation (RR, 2.1; 95% CI, 1.0 to 4.3; $p$=0.04). Conclusion: Survival after UCB transplantation was similar to survival after MRD and URD transplantation. For patients lacking an HLA matched donor, the use of UCB is a suitable alternative.

This study was carried out to evaluate the quality characteristics of Takju, Yakju, Spirit made by various cereal Nuruks which were made by Jokuk(whole wheat), Bunkuk(wheat flour), Maekkuk(whole barley). pH, Brix, cell number of yeast, alcohol content, flavors, organic acid, and sensory evaluation of brews were employed to analyze current study. Results showed that pH value of brews during fermentation decreased, while Brix value increased. In addition, alcohol contents increased up to 11 day's fermentation, but there were no significant differences among Jokuk, Bunkuk and Maekkuk(p<0.05). Cell numbers of yeast dramatically increased up to 5 day's fermentation, and then decreased. After 13 day's fermentation cell numbers of yeast were similar among Jokuk, Bunkuk and Maekkuk. In terms of analysis of flavor components, acetone and n-amyl alcohol were not detected in all brews, however fusel oil level was 494.65 mg/L in Maekkuk, and 525.4 mg/L in Bunkuk. Lactic acid showed the highest level in organic acid analysis. Furthermore, Jokuk and Maekkuk showed highest score in Takju, Maekkuk showed highest score in Yakju in sensory evaluation, although Jokuk, Bunkuk, and Maekkuk revealed similar score in spirit.

This study aimed to analyze the effects of nursing students' self efficacy, communication skill, and nursing skill on their application of the fundamental nursing practice program with clinical scenario. This study used a nonequivalent control group pretest-posttest design. The participants were second year nursing students; the experimental group had 35 participants and the control group had 46. The clinical scenario based program was applied and evaluated the self efficacy, communication ability, and nursing ability. The results of the study showed an increase in self-efficacy in the experimental group, and this increase was statistically significant as compared to that in the control group (t=2.06, p=.042). Communication skill increased in the experimental group, but it was not statistically significant as compared to the control group (t=.28, p=.778). Nursing skills slightly increased in the experimental group compared to that in the control group (t=2.46 4, p=.016). The fundamental nursing practice combining the clinical scenario can help students' understanding of clinical situation and nursing skills.

In order to obtain basic informations on establishment of culture system for Cassia tora L. in the southern part of Korea, under vinyl mulching and non mulching conditions, the characters of growth and yield following the difference of fertilization quantity were investigated. All characters, stem length, stem diameter, number of branches, number of pods per plant, pod length, and number of grains per pod, etc., were excellent under the vinyl mulching condition, and of these growth characters, stem diameter, number of pods per plant, and number of grains per pod, etc. were most excellent in the district of N-P$_2$O$_{5}$-K$_2$O=8-6-6Kg /10a. Weight of 1000 grains and seed yield were also high under the vinyl mulching condition, and starting form the district of fertilization quantity N- P$_2$O$_{5}$-K$_2$O=8-6-6Kg /10a, the districts of increasing or decreasing fertilizer tended to be less yield. Also under the vinyl mulching and non mulching, the dispersive analyses of useful characters following the difference of fertilization quantity, were acknowledged to be worth of attention.

The aim of this study was to investigate the burden and caregiving satisfaction of primary family caregivers of older adults with dementia, and to identify cultural predictors and non-cultural predictors of burden and caregiving satisfaction. This study included 112 primary family caregivers of community-dwelling older adults with dementia who utilized 13 dementia day care centers in Seoul or Gyeonggi-do. Data were collected by survey questionnaires. The majority of the primary caregivers were female (81%) and daughters-in-law (46%). The mean burden score was 49.4 and the mean caregiving safisfaction score was 42.3. Regression analyses revealed that the significant predictors of primary caregivers' burden were the non-cultural factors of caregiver's perceived health (β= .421, p= .049) and care recipient's memory and behavioral problems (β= .183, p= .041). The cultural factor of familism (β= .466, p= .005) was the only significant predictor of caregiving satisfaction. There is more need to develop programs which improve caregiver's burden and caregiving satisfaction. Strategies to increase caregiver's utilization of the programs also need to be developed.

Objective : Achyranthes japonica Nakai (AJ) has been classified as a herb that activates blood flow and clears the stagnated blood. In this study, we evaluated its anti-nociceptive and anti-inflammatory activity in animals to clarify the effect of AJ on pain or inflammation. Methods : ICR mice and Sprague-Dawley rats were pretreated with an ethanolic extract of AJ with two dosages of 200 mg/kg (p.o.) and 400 mg/kg (p.o.). Nociceptive responses of acute pain were determined by hotplate and tail-flick tests. The effects of AJ on inflammation were evaluated by flexion/extention test and mechanical hyperalgesia test in models induced by both carrageenan and Complete Freund's Adjuvant (CFA). Results : AJ showed significant analgesic effects in both hotplate and tail-flick tests at the dose of 400 mg/kg. It also produced a significant inhibition of carrageenan-induced paw edema and CFA induced arthritis in rats at the dose of 400 mg/kg. Conclusion : We have demonstrated the analgesic and anti-inflammatory properties of an 80% ethanolic extract of AJ in animals. This suggests the application of AJ in relief of pain or inflammatory disease.

The objective of this study was to evaluate whether nutrient intakes and serum biochemical indices are associated with the skin condition of humans. Anthropometric data, skin surface hydration, ceramide content, dietary intake of nutrients and serum lipids (total cholesterol, HDL-, LDL-cholesterol, TG, MDA: malondialdehyde, TAS: total antioxidant status) were obtained from 36 healthy young women. Subjects were classified into 2 groups {LM: Low Moisture Group (n = 20) , HM: High Moisture Group (n = 16)} by forehead skin hydration. The results of this study were as follows: The average age, BMI, total body water, LBM, body fat$\%$, WHR, forehead hydration, ceramide content were 20.2 yrs, 20.7, 28.81, 39.2 kg, $28.0\%$, 0.8, $44.3\%$, and 1.05 $\mu$g/$\mu$g protein, repectively. The intakes of SF A (saturated fatty acid) , MUFA (monounsaturated fatty acid) in the HM group were significantly higher (p < 0.05) than in the LM group, but zinc intakes in the LM group were higher than in the HM group. Serum levels of TAS in the LM group (1.27 mmol/l) were significantly higher (p < 0.05) than that of in the HM group (1.20 mmol/l). Whereas other lipid levels were not significantly different, intakes of vitamin $B_{6}$ and folate showed significant positive correlation with the forehead hydration (r = 0.447, r = 0.377). Intakes of calcium and phosphorus showed significant negative correlation with forearm ceramide content (r = -0.496, r = -0.485). Several associations between nutrient intakes and skin conditions were observed, indicating that changes in baseline nutritional status may affect skin health.

Objectives : To confirm whether acupuncture can suppress the degree of seizure and the activation of astrocytes in hippocampi using kainic acid(KA)-induced epilepsy mouse model. Methods : 8 weeks C57BL/6 mice(20~25 g) were given acupuncture once a day at acupoint HT8(Shaofu) bilaterally during 2 days before KA injection. After an intraperitoneal injection of 30 mg/kg KA, acupuncture treatment was subsequently administered once more(total 3 times), and the degree of seizure was observed for 120 min. The neuronal cell death, pERK expression, and astrocyte activation confirmed 1 hour and 24 hours after KA injection. Results : Acupuncture treatment at HT8 suppressed KA-induced epileptic seizure. One hour after KA injection, the pERK expression was increased, which was reduced by the acupuncture treatment. Twenty four hours after injection, the treatment decreased the KA-induced neuronal cell death, the interleukin-$1{\beta}$ expression and the astrocyte activation in the CA3 region of the mouse hippocampus. Conclusions : Acupuncture treatment at HT8 decreases the KA-induced epileptic seizure, the neural cell inflammation and death.

White blood cells (WBCs) are present in most human ejaculates, but abnormally high concentration of seminal leukocytes may reflect an underlying pathological condition. The World Health Organization (WHO) has defined leukocytospermia as status of more than $10^6$ WBC/mL of semen. The purpose of this study was firstly, to compare the outcomes between conventional IVF and ICSI in leukocytospermia, and secondly, to investigate whether ICSI may be an alternation treatment for patients with leukocytospermia. Total 346 cycles of conventional IVF and ICSI candidates underwent IVF cycles at Eulji Hospital Infertility Clinic. Semen Parameters including concentration, motility, morphology of spermatozoa and concentration of leukocytes were assessed from the raw ejaculates. There was no difference in sperm concentration, motility and morphology. The rates of fertilization and good embryo development from ICSI were significantly higher than those from conventional IVF in leukocytospermia (60.4% ＆ 32.5%, respectively for ICSI group and 44.4% ＆ 28.5%, respectively for IVF group, P<0.00l). The pregnancy rate after ICSI was also higher than that from conventional IVF (34.0% vs 29.1 %, P<0.05). These results indicate that the presence of seminal leukocyes (> 1$\times10^6$ WBC/mL of semen) is adversely related with fertilization, embryo development and pregnancy rate. Therfore the measurement of seminal leukocytes in routine semen analysis appears to be of prognostic value with regard to male fertilizing potential. In conclusion, it is suggested that ICSI is an alternative choice of treatment for patients with leukocytospermia.
