Purpose : The increasing use of ultrasonography has allowed for an increase in the of the detection of congenital hydronephrosis, and the clinical outcomes of congenital hydronephrosis are widely varied. In this study, the necessity of voiding cystourethrography in neonate with hydronephrosis to rule out vesicoureteral reflux (VUR) was evaluated. Methods : Between January 2004 and December 2007, we reviewed the medical record of 157 childrens with congenital hydronephrosis detected within 1 month of age. The severity of hydronephrosis was graded by SFU (Society of Fetal Urology) system, and anterior posterior pelvic diameter (APPD). We evaluated the relationship between severity of hydronephrosis and incidence of VUR by using SPSS windows version 16.0. A P-value<0.05 is considered to be statistically significant. Results : Total renal unit number was 254, and 20(7.8%) renal units had VUR. We did not find any relationship between hydronephrosis grade the presence of VUR grade (P>0.05). In addition, there was no statistical significance between APPD, laterality of hydronephrosis and VUR incidence. However, renal units with VUR had lower spontaneous resolution rate (P<0.05), compared to renal units without VUR. Conclusion : In this study, there was no statistical significance between the severity of hydronephrosis and presence of VUR. Therefore, voiding cystourethrogram is recommended for all children with hydronephrosis to rule out VUR, regardless of the severity of hydronephrosis. 목 적 : 산전 초음파 이용의 증가로 인하여 선천성 수신증 발견 빈도가 증가하고 있고 VUR이 수신증의 원인 중 하나이다. 본 연구에서는 선천성 수신증의 정도와 VUR의 연관성을 조사하여 배뇨성 방광요도 조영술의 필요성을 알아보고자 하였다. 방 법 : 2004년 1월 1일 부터 2007년 12월 31일 까지 생후 1개월 이내에 선천성 수신증이 진단된 157명의 환아 254구의 신장을 대상으로 수신증의 등급 및 신우 전후직경이 VUR의 빈도와 연관성이 있는지를 연구하였다. 통계 분석은 SPSS 16.0을 이용하여 Chi-Square 법, ANOVA 법으로 분석하였으며, P값이 0.05 미만인 경우를 통계적으로 유의한 것으로 분석하였다. 결 과 : 수신증이 있는 254구의 신장 중 7.8%에 해당하는 20구의 신장에서 VUR이 동반되었다. 수신증 등급과 신우 전후직경은 VUR의 빈도와는 의미있는 상관관계가 없었고, 좌측이 우측보다 수신증의 정도와 VUR 등급이 유의하게 높았으며 VUR이 존재하는 경우 수신증의 자연 소실률이 현저히 낮은 것으로 나타났다. 결 론 : 본 연구에서 수신증 등급과 VUR의 유무와는 통계적 유의성이 없었다. 따라서 수신증의 심한 정도에 관계없이 모든 환아에서 VUR 유무를 확인하기 위해 배뇨성 방광요도조영술은 시행되어야 한다.

농작물 생산에 있어서 병원균 침입에 의한 피해를 줄이는 것은 아주 중요한 과제이다. 식물은 스스로도 생체 방어 신호 전달 기작을 가지고 있지만 그 피해를 줄이는데 있어서 한계가 있다. 본 연구는 콩과 식물에서 분리한 식물생체방어 신호전달 유전자인 SCaM-5를 토마토에 형질전환하여 형질전환 식물체를 작성하고 병 저항성에 관한 실험을 수행한 것이다. SCaM-5 유전자가 형질전환 된 토마토에서는 pathogen-related(PR-5) 유전자를 항상 발현시킴으로서 계속적으로 식물 생체방어 신호기작을 활성 시킨다는 사실을 확인하였다. 또한, SCaM-5를 형질전환 시킨 토마토는 식물에 막대한 피해를 주는 중요한 곰팡이 (P. capsici와 F. oxysporm)와 bacteria (Pst DC3000)에 대하여 병 저항성을 가진다는 것을 검증하였다. The calmodulin as a Ca$^{2+}$-binding protein mediates cellular Ca$^{2+}$ signals in response to a wide array of stimuli in higher eukaryotes. Plants produce numerous calmodulin isoforms that exhibit differential gene expression patterns and sense different Ca$^{2+}$ signals. SCaM-5 is a soybean calmodulin that is involved in plant defense signaling. Here, we constructed a SCaM-5 CDNA under control of CaMV 35S promoter and transformed it into tomato (Lycopersicon esculentum). The constitutive over-expression of SCaM-5 in tomato plants exhibited a high levels of pathogenesis-related (PR) gene expression, and conferred an enhanced resistance to two fungal pathogen (Phytophthora capsici, Fusarium oxysporum), and a bacterial pathogen, Pseudomonas syringae pv. tomato DC3000. Thus, this results collectively suggest that SCaM-5 plays an important role in plant defense of tomato.

Purpose : The purpose of this study was to examine the levels and influencing factors of the perceived stress and life-satisfaction among mothers of children with disability. Methods : 55 mothers were selected for this study and the self-reporting method to the structured questionnaire were used to collect the data. The data were analyzed with the frequency, t-test, one-way ANOVA, Duncan test using SPSS 14.0 for window programs. Results : Firstly, the level of total perceived stress of the mothers of children with cerebral palsy was 44.28/75, and the average of the items of the perceived stress was 2.95/5. The highest level of subcategory of the perceived stress, 10.82/15, was in parent role stress, and the lowest level of subcategory of the perceived stress, 3.88/10, was in children developmental stress. There were statistically significant differences in the mother's level of stress according to their ages, employment, occupation, and daily activity time and sleeping time. Secondly, the level of life-satisfaction was 3.17/7, and statistically significant difference was found by the treatment cost. Conclusions : We suggest that these variables need to be considered when the stress intervention programs for the mothers of children with cerebral palsy are developed.

Purpose: The purpose of this study was to determine the effects on improvement of the range of motion in the TM joint. Methods: 26 subjects who have TM joint limitation were divided to passive movement group(n=13, $21.3{\pm}2.95$ years) and active movement group(n=13, $20.62{\pm}1.39$ years). All of the subjects were treated 5 to 10 minutes per one time, five times once a week for 4 weeks by the physical therapist. The open bite and cross bite were investigated at before, during(2 wks) and treatment(4 wks). Results: In order to assure the statistical significance of the result, a Repeated measures ANOVA were applied at the 0.05 level of the significance. There was a significant difference in terms of the rates of open bite mean change in within-open bite effects among pre-test, post-test 2weeks and post-test 4weeks in each group(P=0.029). There was no significant difference in the rates of mean change in between-open bite effects(P=0.441) but interactions between two types of effects(P=0.025) were statistical significance among pre-test, post-test 2 weeks and post-test 4 weeks in each group. There was no significant difference in the rates of mean change in within-close bite effects(P=0.112), between-cross bite(P=0.179) and interactions between the two types of effects(P=0.098) among pre-test, post-test 2 weeks and post-test 4 weeks in each group.

This study applied a segmented hard shell design on knee protectors for children with the objective of increasing mobility. The prototype of the hard shell that does not correspond to movement of the body among components of the knee protector was developed. Surface modeling was conducted based on 3D knee data to enhance comfort through optimized fit on the knee joint where the hard shell would be worn. For this, previous studies on changes in skin near the knee joint during knee flexion were reviewed to establish basic segmental lines. The basic design included six segments, and the number of segments was used as the design variable by increasing or decreasing it to 0, 3, 6, 9, and 14 segments. A prototype was produced from 3D printing with TPU material, worn for wearing assessment. Results revealed fewer numbers of segments resulting in less fit with the body, while actual appearance was stable. Meanwhile, the number of proper segments improved better fit with the body during movement. The wearing assessment revealed the amount of gap reflects change in skin length depending on movement. Assessment results demonstrated basic segment design, S6 with 6 segments, had the best design and most optimized fit. Findings in this study can provide key data for designing knee protection products for children.

이효정,엄란이,이예진,Lee, Hyojeong,Eom, Ran-i,Lee, Yejin 한국섬유공학회 2017 한국섬유공학회지 Vol.54 No.4

In this study, the physical properties of commercially available 3D spacer fabrics are analyzed, and their applicability to functional apparel is investigated. Six samples were prepared by purchasing four types of 3D spacer fabric with different thicknesses and surface structures (A1, B1, C1, and D1). Moreover, A2 and B2 are produced by two layers of A1 and B1, respectively, and their applicability to functional apparel was examined through the evaluation of the tensile strength, elongation, air permeability, Q-max, and thermal insulation. In addition, based on these, 3D spacer fabric modeling for 3D printing was attempted. It was observed that the tensile strength was higher in the wale direction than in the course direction, and it increased with increasing thickness. The elongation was the highest in C1, with large surface holes and low density. The air permeability was also the highest in C1, with large holes and relatively high thickness. It was observed that the air permeability of A1 and B1 significantly decreased when they were two layered fabrics. With regard to the Q-max, C1 and D1, which were thick samples, exhibited high warm feeling, while A1 and B1, which were thin samples, exhibited high cold touch. Finally, the thermal insulation was the highest in D1, which was the thickest sample, demonstrating a positive correlation with thickness and volume. As a result, considering the advantageous properties of each sample and the related specific performance required for functional apparel obtained from the above results, it was confirmed that the 3D spacer fabric could be applied to functional apparel.

This study was to investigate the dffects of a color reversal visual perceptual training program on spastic cerebral palsied children's figure-ground discrimination disabilities and to investigate the difference between the control group and experimental group. Subjects of the study were composed of children with spastic cerebral palsy whose age varied from five to seven years old, whose I.Q. was over 70 and whose P.Q. was over 70. Implication of this study can be summarized as follows; First, Perceptual training and speech training programs should be emphasized to improve the preparative ability of spastic cerebral palsied children. Problems of perception cerebral palsied children are concerned with figure-ground discrimination disability. Second, Though it was demonstrated that color reversal visual perceptual training program can be effective through the prestudies and this study, more researches should be made to apply this kind of theory in real education environments. More interest in different color forms for training of cerebral palsied children should be taken. Third, Reprecations of the study should be considered with modified group identities(age, I.Q., P.Q.).
