Background: Flat-footed persons with collapsed medial longitudinal arch lose flexibility after skeletal maturity, resulting in several deformities and soft tissue injuries. Although arch support taping is usually applied in the clinic to support the collapsed arch, research on the use of different types of tape for more efficient arch support in flat-footed persons is lacking. Objects: The purpose of this study was to examine three conditions (barefoot, kinesio tape, and dynamic tape) and compare their effects on static and dynamic balance in persons with asymptomatic flexible flatfoot. Methods: Twenty-two subjects (9 females and 13 males) with asymptomatic flexible flatfoot participated in this study. The subjects performed the Y-balance test to measure the composite reach score. The subjects also performed a 30-second standing test to measure the center of pressure (COP) path length and a walking test to measure anteroposterior and lateral variability using the Zebris FDM system. One-way repeated-measures analysis of variance compared the three conditions applied to the subjects’ feet for each balance variable. Results: The composite reach score significantly increased following the application of dynamic tape compared with barefoot and that of kinesio tape compared with barefoot. There was no significant difference in the COP path length during standing among the three conditions. Anteroposterior and lateral variability during walking significantly with dynamic tape application compared with barefoot. Conclusion: The results of this study suggest that, in persons with asymptomatic flexible flatfoot, application of kinesio tape and dynamic tape may be effective in increasing the composite reach score in Y-balance test, whereas application of dynamic tape may be effective in reducing anteroposterior and lateral variability during walking.

ObjectiveTo compare image qualities between vendor-neutral and vendor-specific hybrid iterative reconstruction (IR) techniques for abdominopelvic computed tomography (CT) in young patients. Materials and MethodsIn phantom study, we used an anthropomorphic pediatric phantom, age-equivalent to 5-year-old, and reconstructed CT data using traditional filtered back projection (FBP), vendor-specific and vendor-neutral IR techniques (ClariCT; ClariPI) in various radiation doses. Noise, low-contrast detectability and subjective spatial resolution were compared between FBP, vendor-specific (i.e., iDose1 to 5; Philips Healthcare), and vendor-neutral (i.e., ClariCT1 to 5) IR techniques in phantom. In 43 patients (median, 14 years; age range 1–19 years), noise, contrast-to-noise ratio (CNR), and qualitative image quality scores of abdominopelvic CT were compared between FBP, iDose level 4 (iDose4), and ClariCT level 2 (ClariCT2), which showed most similar image quality to clinically used vendor-specific IR images (i.e., iDose4) in phantom study. Noise, CNR, and qualitative imaging scores were compared using one-way repeated measure analysis of variance. ResultsIn phantom study, ClariCT2 showed noise level similar to iDose4 (14.68–7.66 Hounsfield unit [HU] vs. 14.78–6.99 HU at CT dose index volume range of 0.8–3.8 mGy). Subjective low-contrast detectability and spatial resolution were similar between ClariCT2 and iDose4. In clinical study, ClariCT2 was equivalent to iDose4 for noise (14.26–17.33 vs. 16.01–18.90) and CNR (3.55–5.24 vs. 3.20–4.60) (p > 0.05). For qualitative imaging scores, the overall image quality ([reader 1, reader 2]; 2.74 vs. 2.07, 3.02 vs. 2.28) and noise (2.88 vs. 2.23, 2.93 vs. 2.33) of ClariCT2 were superior to those of FBP (p < 0.05), and not different from those of iDose4 (2.74 vs. 2.72, 3.02 vs. 2.98; 2.88 vs. 2.77, 2.93 vs. 2.86) (p > 0.05). ConclusionVendor-neutral IR technique shows image quality similar to that of clinically used vendor-specific hybrid IR technique for abdominopelvic CT in young patients.

Empirical antipruritic treatment often fails, as the mechanism has not been fully elucidated. Objectives: The aim of this study was to evaluate the manifestation of transient receptor potential vanilloid 3 (TRPV3), transient receptor potential ankyrin 1 (TRPA1) and other related receptors in post burn pruritus. Methods: Sixty-five burn patients with (n=40) or without (n=25) pruritus were investigated, including skin biopsy and clinical assessments such as VAS (Visual analogue scale) for pruritus, PSAS (Patient scar assessment scale), and OSAS (Observer scar assessment scale). Keratinocytes and fibroblasts from skin biopsy samples were separated and real time PCR, western blotting, intracellular Ca2+ measurements were performed. Results: Real time-PCR showed that mRNA of TRPV3 was significantly increased in keratinocytes from pruritic burn scars than in keratinocytes from non-pruritic burn scars. With TRPV3 activation, intracellular Ca2+ concentrations were more significantly increased in keratinocytes from pruritic burn scars than in those from non-pruritic ones. Additionally, mRNA and protein levels of protease-activated receptor 2 (PAR2) and neurokinin-1 receptor (NK1R) were also significantly increased in pruritic burn scars. Conclusion: We confirmed that TRPV3, PAR2, and NK1R were highly expressed in pruritic burn scars. These results may help determine a novel mechanism for post burn pruritus.

Hepatoblastoma is a rare pediatric malignancy which frequently presents at an advanced un resectable stage. With the neoadjuvant chemotherapy, improved resectability and survival have been reported. Twenty children with biopsy proven hepatoblastoma were treated during the period between January 1987 and June 1995. Median age at diagnosis was 13 months(2 months to 7 year and 10 months), and 13 were male. Histologic profile was 13 epithelial(5 fetal, 4 mixed, 1 embryonal, 3 undetermined), and 5 mixed mesenchymal and epithelial and 2 of undetermined type. Chemotherapy effectively reduced the tumor volume($p$=0.008), and was able to convert 7 out of 9 initially unresectable cases(78%) to resectable ones. Twelve radical and 2 palliative operations were done with or without adjuvant chemotherapy. The Median follow up period was 33 months and the median survival was 26 months. The group with curative resection had a 61.1% 5 year survival rate, but none of palliative resection group survived more than 13 months($p$=0.0001). In univariate analysis for prognostic factors revealed, large tumor size at diagnosis and abscence of thrombocytopenia were associated with poor survival, but these differences were not statistically significant. Histological pure fetal type did not mean a better prognosis. Even with a recent neoadjuvant chemotherapy, the strategy should be focused on the radical resection as early as possible.

Prevalence of the coronary artery anomaly is approximately 1% of the population who undergo coronary angiography. The anomalous origin of the right coronary artery (RCA) as a branch of the left anterior descending artery (LAD) is a very rare variation of single coronary artery. The anatomic variation has no clinical significance. However, some patterns of congenital coronary artery anomalies can cause clinical manifestations of myocardial ischemia, reducing myocardial perfusion. We report on a case of a 78-year-old man who had anomalous RCA arising from the proximal part of the LAD, which probably caused chest pain.

Park, Un-Yong,Lee, Jae-One,Lee, Dong-Rak,Hong, Jung-Soo Korean Society of Surveying 2004 Korean journal of geomatics Vol.4 No.2
We can process and compute the position, velocity and time by satellite signals of GPS. The signals are used to compute positioning of three dimensions and timing offset of the receiver clock when we can track the tour satellite signals at least. One of the specified aims is to use less expensive single frequency code/carrier phase GPS receivers, which are typically around half the price of dual frequency receivers. In the study, the author analyzed the accuracy and applicability of frequence linear combination using triangulation points evaluated distance limitation.

( Hye One Kim ),( Soo Ick Cho ),( Jin Hye Kim ),( Bo Young Chung ),( Hee Jin Cho ),( Chun Wook Park ),( Cheol Heon Lee ) 대한피부과학회 2013 Annals of Dermatology Vol.25 No.2
It is well known that atopic dermatitis (AD) is related to food hypersensitivity, although its prevalence varies among several studies according to age group, severity, country, survey time, and test method. Objective: To examine the prevalence and status of food hypersensitivity among childhood AD patients in Korea. Methods: A total of 95 patients were enrolled in the study. The history of food hypersensitivity was collected by interviews. The severity of AD was evaluated by eczema area and severity index (EASI). We took blood samples to measure serum total and food-specific immunoglobulin E (IgE) levels. Based on the histories and serum IgE levels, open oral food challenge (OFC) testing was performed to confirm food hypersensitivity. Results: Forty- two (44.2%) of the 95 AD patients had histories of food hypersensitivity. They reported that the most common suspicious foods were egg (n=13, 13.7%), pork (n=9, 9.5%) and cow milk (n=8, 8.4%). The mean EASI score was 16.05±9.76. Thirty-nine (41.1%) of the 95 patients showed elevated serum food-specific IgE levels. The specific IgE levels were elevated for egg (n=17, 17.9%), milk (n=12, 12.6%), peanut (n=10, 10.5%) and wheat (n=8, 8.4%). Fifty-one (53.8%) of 95 patients underwent open OFC, and only 7 (13.7%) of these patients showed positive reactions. Conclusion: The overall prevalence of food hypersensitivity in patients with childhood AD in Korea was 8.3% (7/84). The most common foods causing food hypersensitivity were egg and milk. Among the foods causing hypersensitivity, AD patients in Korea often underestimated peanut, while they overestimated pork.

박미규(Park, Mi-Kyu),조진희(Jo, Jin-Hee),윤두원(Yoon, Two-One),황희연(Hwang, Hee-Yun) 한국주거환경학회 2015 주거환경(한국주거환경학회논문집) Vol.13 No.3
This study looked into how residents’ satisfaction with community facilities would be related to community spirit in order to understand effects of user satisfaction with public spaces in Cheotmaeul Town, which were designed to improve residential community spirit, on community spirit of the residents. The research on distinctive plan concepts of Cheotmaeul Town and components of the community spirit led the study to have better understanding on residents’ satisfaction and community spirit and as a consequence, factors to be measured were extracted. The study also conducted a survey targeting residents of Cheotmaeul Town. As carrying out the descriptive statistical analysis and ANOVA on the findings of the survey, the study extracted the residents’ satisfaction with the community facilities. With the help of the multiple regression analysis, the study came up with the distinctive plan facilities to affect the cultivation of community spirit and eventually, it drew the relation of the Cheotmaeul Town residents’ satisfaction with the community spirit. The findings of the research revealed that use of parks and green belts, use of complex community facilities, exchanges among neighbors, education and welfare facilities and others as in use types of facilities are considered these factors to influence the improvement of the residents’ community spirit. The study now suggests that any follow-up researches should talk about issues to be resolved at a stage of city construction, calculated management factors, residents’ participation and others from various points of view, and that will in the end help the study find not only causes for why some of the facilities and environments that had been designed to improve local communities do not help the growth of the community spirit but also ideas on how to make all the facilities and the environments contribute to the cultivation of the community spirit.
