To assess the performance of contrast-enhanced three-dimensional(3D) magnetic resonance venography(MRV) of the pelvis and lower extremities in patients with varicose vein. Conventional and MR venography were peformed in 14 legs in 14 patients and duplex doppler sonogram and MR venography were performed in 30 legs in 24 patients referred fo revaluation of varicose vein. For analysis, the venous system was divided into 13 segment in Conventional and MR venographic images, For detection of reflux to greater saphenous vein, duplex doppler sonogram and MRV were peformed. In ascending venogram and MRV, 182 venous segments potentially could be seen. MRV depicted 156 segments. 8 segments among depicted segments at MRV were not seen at ascending venogram. Ascending venogram depicted 182 segment. 4 segments among depicted segments at ascending venogram were not seen at MRV. MRV detected 38 varices and ascending venogram detected 34 varices, When two tourniquets were placed around the ankle and knee with valsalva maneuver, MRV detected reflux in 16 legs of 22 legs. Duplex doppler sonogram detected reflux in 26 legs of 30 legs. Contrast-enhanced 3D MRV comprehensively displays the lower extremity venous system and permits assessment of varicose vein. MRV with valsalva maneuver permit assessment of reflux to greater saphenous vein.

This study was peformed to design a safe air-pressure reduction system which can absorb rapidly rising intraluminal pressure during intussusception, and comparison with other reduction systems to test its clinical availability. The air-pressure reduction system consisted of a pressure gauge, air insufflators a pressure controller, buffers, and rapid exhaustion devices, and to determine its absorbability, it was connected with a bowel model. By using it in 20 infants with intussusception, we compared the absorbability of our air-pressure reduction system with preexisting systems. While extraluminal pressure was applied to the bowel model in which baseline intraluminal pressure was set to 120mmHg, this rose to 176mmHg(56mmHg high to standard, 100%) in the direct infusion system, but to only 130mmHg (10mmHg high to standard, 17.9%) in a system connected to a large buffer of 10,500㎖ capacity. Immediately after the application of extraluminal pressure for less than 1 sec, this air-pressure reduction system showed better absorbability than the hydrostatic reduction system. Applying this system to 20 infants with intussusception, this was successfully Reduced in 19 cases(95%), without complications. In this experiment, it was proved that the system absorbed rapid intraluminal pressure elevation. Its use would help prevent bowel perforation during air reduction occurring during.

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.

한미애,김지연,장기연,박미진 대한감각통합치료학회 2010 대한감각통합치료학회지 Vol.8 No.1

목적 : 본 연구는 주변 환경에 민감하고 감정기복이 심한 감각조절장애 아동에게 무게감 있는 조끼 착용을 통한 고유수용성 감각을 제공하여 아동의 문제행동에 미치는 영향을 알아보기 위하여 실시하였다. 연구 방법 : 연구 대상자는 일반초등학교 1학년에 재학 중인 만 7세 남아로 연구설계는 ABA’단일사례연구를 사용하였고, 14회기 실험을 실시하였다. 중재기간(B)동안 1.3kg의 무게를 첨부한 조끼를 착용하고 학습인지교육을 받았다. 결과 : 치료회기가 진행될수록 의자에서 엉덩이를 떼고 일어나거나 몸을 앞/뒤, 좌/우로 흔드는 경우 및 엄지손가락을 입에 넣기, 손등 입으로 가져가기, 손장난하기 등 행동적 측면에서의 문제행동은 점차 감소되는 경향을 보였다. 결론 : 연구결과 무게감 있는 조끼를 착용한 후 아동의 문제행동이 회기가 지날수록 감소되는 양상을 보였다. 무게감 있는 조끼가 감각조절장애 아동의 문제행동에 대한 감각통합치료의 효과 유지에 미치는 영향을 설명하는데 본 연구설계 및 중재기간상 제한점이 있어서, 무게감 있는 조끼가 감각조절장애 아동의 문제행동에 영향을 주었다기보다는 감각통합치료를 지속적으로 실시한 결과로 생각할 수 있다. 따라서 추후 연구에서는 연구설계의 변형이나 연구회기의 증가를 통해 무게감 있는 조끼가 감각통합치료의 효과를 지속하는지에 대해 명확히 알아보는 것이 필요하고, 감각조절장애 아동에게 무게감 있는 조끼를 착용시키는 것에 대한 적용방법, 무게, 적용시간에 대한 효율적인 프로토콜을 제시하는 연구가 필요할 것이다. Purpose : The purpose of the study is to find out the effect of wearing a weighted vest for sensory modulation disorder children. Methods : The participant of the study was an elementary school student, male, aged 7. The ABA single case study was used to design the study which was performed for 14 sessions. During the mediation period(B), the participant received the study cognitive education wearing weighted vest weighing 1.3kg. Results : Abnormal behaviors such as suddenly standing up from the chair, shaking body front and back, and left and right, sucking his thumb and putting the back of his hand to his mouth showed tendency to decrease gradually. Discussion : The participant's abnormal behaviors decreased as the sessions went by, which means the sensory integration therapy can improve the behavior of the child suffering the sensory modulation disorder. The design of the study had certain limitation to explain the influence a weighted vest to sustain the effect of the sensory integration therapy. New study design is needed for the extended studies to prove the lasting effect of a weighted vest for the sensory integration therapy and to suggest protocols incorporating wearing know-hows, proper wearing time, and the weight of a weighted vest.

한미애,장기연,김지연,한수연 대한감각통합치료학회 2009 대한감각통합치료학회지 Vol.7 No.2

목적: 본 연구의 목적은 발달장애 아동에게 그룹 감각통합치료를 적용하여 아동의 운동기능 및 사회성 증진에 어떠한 영향을 미치는지 알아보고자 한다. 연구방법: 대전 S아동연구소 감각통합치료실을 이용하는 아동 중, 발달장애 및 정신지체로 진단받은 아동 10명을 대상으로 하였다. 실험군은 그룹 감각통합치료에 참여하는 아동 5명, 대조군은 개별 감각통합치료에 참여하는 아동 5명으로 주 1회 90분, 20주 동안 적용하였다. 아동의 운동기능 및 사회성 증진 정도를 측정하기 위한 사전·사후 검사로 운동적합성 검사(Bruini nks-Oseretsky test of Motor Proficiency 2), 한국판 적응행동검사(Korean-Scales of Independent Behavior­Revised) 그리고 사회성숙도 검사(Social Maturity Scale)를 사용하였다 . 결과: 그룹 감각통합치료 적용 전·후 실험군 대부분의 아동이 손/상지협응(Manual coordination)과 신체협응(Body coordination), 사회성 전반적 영역에서 기능향상을 보였지만, 통계적으로 유의미하지 않았다. 그러나 그룹 감각통합치료 프로그램 전후 운동기능 및 사회성 향상의 차이는 실험군 아동이 대조군 아동보다 더 크게 나타났으며 특히 손/상지협응(Manual coordination), 손기민성(Manual dexterity) 하위항목, 사회성숙도 검사의 사회연령, 사회지수에서 통계적으로 유의미하게 나타났다. 결론: 본 연구결과를 통하여 그룹 감각통합치료 프로그램이 발달장애 아동의 운동기능 및 사회성 기능증진에 효과가 있음을 알 수 있었다. 추후 보다 다양한 장애 유형의 아동을 대상으로 그룹 감각통합치료 프로그램을 적용하여 그 효과를 증명하는 연구가 진행되어야 할 것이다. Objective : The purpose of this study is to understand whether group Sensory Integration(SI) therapy has the effect on improvement of motor skill and social function for children with developmental disorder. Method : The subjects were recruited among children received sensory integration therapy at a Children’s Development Institute in Dae-Jeon, experimental group is total 5 participating in group sensory in­tegration therapy and control group is also 5 participating in individual sensory integration therapy. The program was constructed for 90 minutes and all children either in the experimental or in the control group went through intervention for 20 weeks. Bruininks-Oseretsky test of Motor Proficiency II, Korean-Scales of Independent Behavior-Revised and Social Maturity Scale were used in order to eval­uate the degree of improvement in motor skill and social function. Results : Most children in the experimental group showed improvement in overall aspects of motor skill and the social function comparing pre-intervention with post-intervention, but they did not show any statistically significant differences. However, comparing experimental group with control group, children in the experimental group showed improvement in motor skill and social function. Futhermore, there is statistically significant improvement especially in manual coordination, manual dexterity, and social age and social quotient in Behavior-Revised and Social Maturity Scale. Conclusions : It is found that a group Sensory Integration therapy program has effect on motor skill and social function for children with developmental disorder in this study. In the future study, group SI therapy should be applied for children with diverse diagnosis in order to generalize the effectiveness of therapy.
