Kang, Ok-Deuk,Kang, Anna,Ryu, Youn-Chul,Lee, Wang-Shik Korean Society of Animal Sciences and Technology 2013 한국축산학회지 Vol.55 No.2

This study was performed on 26 disabled adolescent participants (16 male, 10 female) with the objective of testing changes in equilibrium after engagement in horseback riding. Participants of total 26 persons were divided into three groups as follows: 6 children with Cerebral Palsy (CP), 14 children with Intellectual Disability (ID) and 6 children with Autism (AT). Participants engaged in therapeutic horseback riding (TR) two times per week for 30 minutes per session. The 26 participants demonstrated a considerable increase in equilibrium ability, with an average increase in equilibrium time of $44.22{\pm}50.70$ sec after TR. Equilibrium also increased according to disability group: CP (P < 0.05), ID (P < 0.001), and AT (P < 0.05). TR should be considered as a possible method for improving functionality in the physically disabled. This data may also be usefully applied to the development of a horseback riding program for the improvement of equilibrium in the disabled.

Proposed development platform enables to obtain design with dynamic user interface compare to Web application and it enables to reduce development period. Besides, this platform can reduce network traffic for transaction compare to Web application like JSP. In experimental results, it has been shown that data size of the proposed x-internet platform have 39%(lists of board system), 19%(contents of board system) compare to JSP application. If we repeat this operation, data sizes cab be increased in proportional to repeat the number of times. Since data sizes cause to network traffic, we expect that network traffic of this platform can be reduced.

Others : Effect of Horse Riding on Balancing Ability in Children with Cerebral Palsy

( Ok Deuk Kang ),( Min Soo Kang ),( Anna Kang ) 한국동물자원과학회 ( 구 한국축산학회 ) 2012 한국축산학회지 Vol.54 No.3

This study was conducted to investigate the effect of a horse riding program on balancing ability in children with cerebral palsy. Eleven children(five males and six females) diagnosed with cerebral palsy participated. The horse riding exercises(walking and trotting) were conducted twice per week for 30 minutes during 24 weeks. Balancing ability was measured three times at pre, mid, and post-test using an air pad by the same physical therapist. The data were analyzed using a two-way repeated-measures analysis of covariance with time(0, 12, and 24 weeks) using SPSS version 18.0. A comparison of horse riding between patients with hemiplegia and paraplegia was conducted with the Willcoxon signed-ranktest at a predetermined probability rate of 5%. The results showed a significant increase in balancing ability after horse riding than that before horse riding(p<0.01). The average balancing score increased greater in males(54.59±84.05) than that in females(27.84±12.67) after the horse riding exercise program compared to that before the program(p <0.05). Thus, horse riding exercise was considered an effective to improve balance in children with cerebral palsy. These results provide useful basic data for horse riding for the disabled.

Endothelial Progenitor Cell Cotransplantation Enhances Islet Engraftment by Rapid Revascularization

Kang, Shinae,Park, Ho Seon,Jo, Anna,Hong, Shin Hee,Lee, Han Na,Lee, Yeon Yi,Park, Joong Shin,Jung, Hye Seung,Chung, Sung Soo,Park, Kyong Soo American Diabetes Association 2012 Diabetes Vol.61 No.4

<P><B/></P><P>Impaired revascularization of transplanted islets is a critical problem that leads to progressive islet loss. Since endothelial progenitor cells (EPCs) are known to aid neovascularization, we aimed to enhance islet engraftment by cotransplanting EPCs with islets. Porcine islets, with (islet-EPC group) or without (islet-only group) human cord blood–derived EPCs, were transplanted into diabetic nude mice. The islet-EPC group reached euglycemia by ∼11 days posttransplantation, whereas the islet-only group did not. Also, the islet-EPC group had a higher serum porcine insulin level than the islet-only group. Islets from the islet-EPC group were more rapidly revascularized at the early period of transplantation without increment of final capillary density at the fully revascularized graft. Enhanced revascularization rate in the islet-EPC group was mainly attributed to stimulating vascular endothelial growth factor-A production from the graft. The rapid revascularization by EPC cotransplantation led to better graft perfusion and recovery from hypoxia. EPC cotransplantation was also associated with greater β-cell proliferation, probably by more basement membrane production and hepatocyte growth factor secretion. In conclusion, cotransplantation of EPCs and islets induces better islet engraftment by enhancing the rate of graft revascularization. These findings might provide a directly applicable tool to enhance the efficacy of islet transplantation in clinical practice.</P>

Kang Yunhee,Park Chulwoo,Young Anna Marie Pacheco,Kim Jihye 한국영양학회 2022 Nutrition Research and Practice Vol.16 No.4

BACKGROUND/OBJECTIVES This study examined socio-economic differences in diverse food consumption among children 6–23 months of age in South Asia and Southeast Asian countries. SUBJECTS/METHODS Data from Demographic and Health Surveys in four countries in South Asia (n = 15,749) and four countries in Southeast Asia (n = 10,789) were used. Survey-design adjusted proportions were estimated for the following 10 food items: grains, legumes, dark green leafy vegetables (DGLV), vitamin A-rich fruits, vitamin A-rich vegetables, other fruits and vegetables (OFV), fish, meat, dairy, and eggs. An equity gap was defined as an arithmetic difference in the proportion of each food item consumed in the past 24-hours between the wealthiest and lowest quintiles and between rural and urban areas, denoted by percentage points (pp). RESULTS The consumption of most of the 10 food items was higher in the wealthiest quintiles and urban areas across eight countries. The size of equity gaps was greater in Southeast Asia than in South Asia, particularly for vitamin A-rich fruits (3.3–30.0 pp vs. 0.3–19.6 pp), vitamin A-rich vegetables (12.1–26.7 pp vs. 2.4–5.9 pp), meat (17.7–33.4 pp vs. 3.4–13.4 pp), and dairy (14.7–32.5 pp vs. 3.3–11.4 pp). However, the size of equity gap in egg consumption was greater in Southeast Asia than South Asia (11.2–19.8 pp vs. 11.0–26.7 pp). Relatively narrower gaps were seen in the consumption of grains (0.3–12.9 pp), DGLV (0.6–12.4 pp), and fish (0.1–16.8 pp) across all countries. CONCLUSIONS Equity gaps in food consumption differed by socio-economic status and region. Reducing equity gaps in nutrient-rich foods and utilizing regionally available food resources may increase child dietary quality.

이안나(Anna Lee),홍승우(Seung Woo Hong),나 호(Ho Ra),김은철(Eun Chul Kim),강남여(Nam Yeo Kang),백지원(Jiwon Baek) 대한안과학회 2020 대한안과학회지 Vol.61 No.3

목적: 초광각안저촬영을 통하여 시간경과에 따른 망막진탕의 면적 변화 및 소실 속도를 분석하였다. 대상과 방법: 망막진탕으로 진단받은 환자의 33안을 대상으로 첫 내원 시, 수상 후 3일, 1주 그리고 4주째 초광각안저촬영(ultra-wide field color fundus photography)을 시행하여 망막진탕의 면적 및 소실 속도를 계산하였다. 결과: 평균 관찰기간은 10.8 ± 12.1주(4-44주)였으며, 수상 후 4주째 모든 환자에서 망막 진탕이 합병증 없이 소실되었다. 수상 후 3일에 측정한 관찰 가능한 총 망막의 면적에 대한 망막 진탕 면적의 평균비(8.51 ± 9.66%)는 첫 내원 시(12.23 ± 10.39%)와 비교하여 의미 있는 감소를 보였고(p<0.001), 수상 후 1주째(1.04 ± 2.75%)와도 유의한 차이를 보였다(p<0.001). 그러나 4주째(0.00 ± 0.00%)에는 1주째에 비해 망막진탕 면적의 유의한 감소를 보이지 않았다(p=0.219). 망막진탕의 소실 속도는 첫 3일간, 수상 후 3일에서 1주 사이, 수상 후 1주에서 4주 사이에 각각 12.97 ± 13.44%/day, 19.62 ± 9.22%/day, 0.87 ± 1.87%/day였으며 1주째 회복 속도가 가장 빨랐다(p=0.192, p<0.001). 결론: 초광각안저촬영은 망막진탕의 변화를 정량적으로 분석할 수 있는 검사이며 망막진탕 환자에서 백색화 병변의 감소는 수상 후 1주일까지 대부분 안정화되어 1달째 후유증을 남기지 않고 모두 자연 회복되었다. Purpose: To quantify the size of commotio retinae and investigate its spontaneous resolution over time using ultra-wide field(UWF) color fundus photography. Methods: We analyzed serial UWF color fundus photographs of 33 eyes of 33 ocular trauma patients with commotio retinae. Total visible retinal areas and the areas of commotio retinae were measured at baseline, 3 days, 1 week, and 4 weeks from the initial traumatic event. Results: The median time of observation was 10.8 ± 12.1 (4-44) weeks. Spontaneous resolution of commotio retinae was observed in all patients, and no patients experienced any complications during the follow-up period. The mean percentage of commotio retinae at 3 days significantly decreased compared to the baseline (8.51 ± 9.66% versus 12.23 ± 10.39%; p < 0.001), and more decreased at 1 week (1.04 ± 2.75%; p < 0.001), but no significant differences were observed between 1 week and 4 weeks(0.00 ± 0.00%; p = 0.219). The spontaneous resolution percentages during the first 3 days, between 3 days and 1 week, and during the next 4 weeks were 12.97 ± 13.44%/day, 19.62 ± 9.22%/day, and 0.87 ± 1.87%/day, respectively (p = 0.192 and p < 0.001, respectively). The resolution rate was higher during the first 1 week. Conclusions: We quantified the size of commotio retinae using UWF color fundus photography. Most patients with commotio retinae resolved spontaneously during the first 1 week following trauma, and all cases completely resolved at 1 month without any complications.
