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.

백악질 골화성 섬유종의 치과적 접근 : 증례보고 A CASE REPORT

한지혜,김재곤,백병주,양연미,이선영 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.2

백악질 골화성 섬유종은 가장 흔히 발생하는 섬유 골성 병소(fibro-osseous lesion)로서, 경계가 분명하고, 느리게 성장하는 팽창성의 양성종양이다. 임상적으로 하악골의 소구치와 대구치 부위에서 발생하고, 여성에게서 2배 정도 호발하며, 주로20대에서 30대 사이에서 발견된다. 백악질 골화성 섬유종은 섬유성 이형성증을 포함한 다른 섬유 골성 병소와 감별되어야 한다 백악질 골화성 섬유종의 또 다른 형태인 유년형 골화성 섬유종은 15세 이하에서 발생하며 빠르게 성장하고, 좀 더 골 파괴적인 양상을 보인다. 치료는 병소의 크기에 따른 절제술이고, 재발은 드물다고 알려져 있다. 본 증례는 우측 하악 견치의 미맹술을 주소로 내원한 12세 남자 어린이로, 백악질 골화성 섬유종으로 진단 후, 외과적 적출술을 시행하여 양호한 치유과정을 보이기에 보고하는 바이다. Cemento-ossifying fibroma of the jaws is well circumscribed, generally slow-growing, benign lesions which en-large in an expansile manner. Clinically, it presents as a slowly enlarging lesion commonly in the premolar-molar area of the mandible and only occasionally in the maxilla and other locations. It occurs twice as often in females and primarily in the 20 to 30 year age group. Differential diagnosis should be performed, preferably with other fibro-osseous lesions such as fibrous dysplasia. A faster growing and more destructive variant of cemento-ossifying fibroma sometimes occurs in patients under age 15 and is termed juvenile (aggressive) ossifying fibroma. Treatment is surgical removal with the extent depending on the size and location of the individual lesion. Recurrence is considered rare. A case involving a 12-year-old male patient with delayed eruption of right mandibular canine is discussed. Following an incisional biopsy, the histopathologic diagnosis established was cemento-ossifying fibroma. After the surgical enucleation of the lesion, no sign of recurrence was detected.

위성관측(MSU)에서 유도된 열대 태평양에서의 강수 알고리즘

한지연 이화여자대학교 교육대학원 2003 이화교육논총 Vol.13 No.-

Rainfall algorithm over the tropical Pacific Ocean has been derived, based on monthly mean data of the satellite-observed Microwave Sounding Unit(MSU) channel l(Ch1) at 50.3 ㎓ and channel 2(Ch2) at 53.74 ㎓ brightness temperature, and the rain-gauge observations at 23 island stations during the period from January 1980 to December 1999. In the algorithm, the Ch1 temperature sensitive to low tropospheric hydrometeors is heavily weighted, and the Ch2 temperature which reflects middle tropospheric temperature is also included because of the rainfall dependence on latitude in the tropics. Compared to previous study of Spencer(1993), the present algorithm has a better simulation with respect to rain-gauge values, showing the improvement of 55 ㎜/month in bias, 33 ㎜/month in RMS error, and 0.13 in correlation on an annual basis. This tendency is more pronounced in the convective region of 17.5S-20N. Previous rainfall records from various data sources which include the output of Tropical Rainfall Measuring Mission(TRMM) have been intercompared in order to estimate uncertainties among them Rainfall data, obtained from satellite infrared observation, are more deviated from the average of the records over the subtropics possibly due to clouds without bringing rain. In the meantime, the rainfall derived from microwave observation shows more discrepancy with the average in the high latitude ocean because of the surface emission of sea ice. The seasonal movement and rainfall amounts in the InterTropical Convergence Zone(ITCZ) and the South Pacific Convergence Zone(SPCZ) have been also discussed with interannual variation. Satellite-observed rainfall formula in this study provides rainfall data for data-sparse ocean, and helps us to understand freshwater budget and air-sea interaction.

김일한,노관태,노현식,김지연,우이형,Kung-Rock Kwon,최대균 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.1

연구 목적: 이 연구의 목적은 하악골 충격 시 안면 두개골의 응력 분산양상에 미치는 구강보호장치의 효과에 대해 조사하는 것이다. 연구 재료 및 방법:: 구강보호장치를 제작하고 사람의 머리부위와 치열의 3차원적 유한요소 모델을 컴퓨터 토모그래피를 사용하여 제작하였다. 머리부위의 finite element model은 356,092요소와, 87,099절점으로 이루어져 있다. 그리고 skull과 maxillae, mandible, articular disc, teeth, 그리고 구강보호장치로 구성되었다. 경부의 움직임을 묘사하기 위하여 스프링이 사용되었다. 하악골의 충격점은 gnathion, center of inferior border 와 anterior edge of gonial angle이었다. 충격방향은 수직, 경사방향(45 도), 그리고 수평이다. 충격량은 0.1초당 800 N이었다. 결과: 수직충격을 가한 경우에는 구강보호장치의 장착여부와 무관하게 비슷한 응력과 분산양상이 나타났다(P>.05). 경사충격(45 도)을 가한 경우 구강보호장치를 장착한 모델에서는 응력이 치아와 안면골 및 두개골로 넓게 분산되었으나 이에 비하여 장착하지 않은 모델에서는 치아에 응력이 집중되었다(P<.05). 수평충격을 가한 경우 구강보호 장치를 장착한 모델에서는 응력이 치아와 안면골 및 두개골로 넓게 분산되었으나 이에 비하여 장착하지 않은 모델에서는 치아에 응력이 집중되었다(P<.05). 구강보호장치를 장착하지 않은 모델에서는 상악 치아에 응력이 집중되는 반면, 장착한 모델에서는 모든 충격실험에서 계측된 응력이 매우 낮았으며, 전달된 응력이 상악 치아와 안면골 및 두개골로 넓게 분산되었다. 결론: 구강보호장치는 외부충격 시에 하악에 수직으로 가해지는 충격에는 완충효과가 적었고, 45 도 경사 충격과 수평 충격에는 발생하는 응력을 안면골과 두개골의 넓은 범위로 분산시키고 응력을 감소시켜 응력의 완충 효과가 있었다. PURPOSE. The purpose of this study was to investigate the effects of a mouthguard on stress distribution under mandibular impact. MATERIALS AND METHODS. The FEM model of head consisted of skull, maxilla, mandible, articular disc, teeth, and mouthguard. The impact locations on mandible were gnathion, the center of inferior border, and the anterior edge of gonial angle. And the impact directions were vertical, oblique (45 degrees), and horizontal. The impact load was 800 N for 0.1 sec. RESULTS. When vertical impact was applied, the similar stress and the distribution pattern was occurred without the relation of the mouthguard use (P>.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the oblique (45 degrees) impacts were happened. However, the stress was centralized on the teeth in the model without mouthguard (P<.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the horizontal impacts was occurred. However, the stress was centralized on the teeth without mouthguard (P<.05). For all impact loads, stress concentrated on maxillary anterior teeth in model without mouthguard, on the contrary, the stress was low in the model with mouthguard and distributed broadly on maxillary anterior teeth, facial bone, and skull. CONCLUSION. The mouthguard was less effective at shock absorbing when vertical impact was added. However, it was approved that mouthguard absorbed the shock regarded to the oblique (45 degrees) and horizontal impact by dispersing the shock to the broader areas and decreasing the stress.

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.

한지혜,김재곤,,백병주,양연미,서정아 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.4

성장기 아동의 Ⅲ급 부정교합의 치료에는 많은 악기능 정형장치가 사용되어 왔으며 다양한 형태로 변화하여 발전되어 왔다. Horseshoe appliance는 Schwarz에 의해 소개된 장치로서 elastic의 견인력으로 장치의 free sliding 효과를 통해, 하악와와 과두의 관계를 재정립시켜, 악골 주위의 연조직이나 muscle matrix와 조화되는 새로운 위치에 하악골을 repositioning시켜 악골관계를 개선시킬 수 있다. 또한 하악의 후하방 회전 효과를 극소화시켜 전안면고경의 증가를 방지할 수 있고, 구외 장치에 비해 환자의 협조도가 좋다. 저자들은 전치부 반대교합을 주소로 전북대학교 치과병원 소아치과에 내원한 Ⅲ급 부정교합 환자에게 Horseshoe appliance를 사용한 결과 하악골에 대한 상대적인 상악골의 전방 성장과 교합평면의 반시계방향 회전, 상악 전치의 순측 경사와 하악 전치의 설측 경사로. 3개월 내에 전치부 반대교합이 해소되는 효과를 얻었다. The Horseshoe appliance was introduced by Dr. Schwarz, and it is used to correct sagittal relationships by elastic force in class Ⅲmalocclusion.It minimizes the increment of lower anterior facial height and allows the mandible to be repositioned harmoniously with the soft tissue and muscle matrix of the jaw. It has the advantages of better patient cooperation, easier construction, and more effective modification. In the patients who were treated with Horseshoe appliance, forward growth of maxilla and counterclockwise rotation of occlusal plane with labioversion of maxillary incisors and linguoversion of mandibular incisors were obtained Minimum downward and backward rotation of mandible was accepted, so increasing of lower anterior facial height was minimized.

Ji-Young Yeo,Jong-Il Park,Soo-Yeon Han 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10

Aim(s): This study was aimed to develop a prototype for nursing simulation contents based on Virtual reality (VR) technology. Method(s): This methodological study was conducted through literature review on previous studies, composition of prototype development participants (nursing expert, technical expert, and 3D modeler), expert advice, examination of content validity, prototype design and development. The research period was from October 2020 to April 2021. The final prototype was implemented based on Unreal Engine 4. Result(s): The overall operation stage of simulation was designed into four stages: orientation, pre-practice, simulation practice, and follow-up activities. The prototype contents were designed according to the Han’s principles of virtual reality simulation design and guideline (2019): 1) principle of matching authentic problems in reality, 2) principle of judgement that is suitable for VR technology, 3) principle of similarity to real environment, 4) principle of structural planning, 5) principle of implementing the professional approach, 6) principle of conceptualizing deployment of simulation activity, 7) principle of simple to complex process, 8) principle of virtual recognition, 9) principle of the same operation and selection as reality, 10) principle of providing information, 11) principle of promoting critical thinking, 12) principle of reflection on the whole simulation. By referring to Jeffries’s simulation design, six scenarios of hospitalized children with pneumonia were constructed and content validity was evaluated (CVI=0.99). Conclusion(s): To maximize the effect of virtual reality-based simulation in nursing education, VR contents should be developed through virtual reality-based simulation design that incorporates the characteristics of VR education and learning components of traditional simulation, rather than simply using VR devices as a training method for existing simulation scenarios. Follow-up study should be conducted to analyze the learner"s reaction and confirm the dynamics of the virtual reality contents in real setting.

Agrobacterium tumefaciens를 이용한 bialaphos 저항성 형질전환 벼의 개발

이효연,이춘환,김호일,한원동,최지은,김진호,임용표 충남대학교 생물공학연구소 1999 생물공학연구지 Vol.7 No.-

비선택성 제초제인 bialaphos는 고등식물에 있어서 glutamine 합성을 억제하여 식물체를 고사시킨다. Acetyltransferase에 의해 encoding된 bialaphos 저항성 유전자는 세균 Streptomyces hygroscopicus SF1239로부터 cloning된 것을 사용하였다. Bialaphose 저항성 유전자를 Agrobacterium 감염법을 이용하여 국내에서 재배되는 벼(동진)에 도입한 결과 약 30%정도의 형질전환 식물체를 얻을 수 있었다. T_1세대의 17개체는 hygromycin과 bialaphos에 대한 저항성 유전형질이 3 : 1로 분리되었다. 또한 Southern 분석을 실시한 결과 wild type의 식물체에서는 Bar 유전자의 검출을 볼 수 없었으나 형질전환 식물체의 경우 Bar 유전자의 검출이 가능하였다. T_3 세대의 형질전환 식물체와 wild type의 식물체를 포장상태에서 비선택성 제초제인 바스타를 살포하고 3주 후에 관찰한 결과 형질전환 식물체는 외형적으로 아무런 피해를 받지 않고 정상적으로 생장하였으나, wild type의 식물체와 잡초는 모두 고사하였다. 이상의 결과를 종합해보면 hygromycin과 bialaphos 저항성 유전자는 Agrobacterium 감염법을 이용하여 단자엽 식물인 벼에 도입할 수 있다는 것을 보여준 것이며, 또한 bialaphos 저항성 유전자가 식물에 도입됨으로써 비선택성 제초제에 대한 저항성 식물을 개발 할 수 있다는 것을 보여 주었다. The bialaphos is a potent inhibitor of glutamine synthease in higher plants and is used as a non-selective herbicide. We have used the bialaphos resistant gene (Bar) encoding for an acetyltransferase isloated from Streptomyces hygroscopicus SF1293. Callus derived from mature seeds of rice (Oryza sativa L. cv. Dong Jin) were co-cultivated with Agrobacterium tumefacieus EHA101 carring a plasmid pGPTV-HB containing genes for hygromycin resistance (HygR) and Bar. Transgenic plants showing in vitro resistance to 50 mg/L hygromycin and 10 mg/L bialaphos were obtained by using a two-step selection/regeneration procedure. Transformation efficiency of rice was about 30% which was as high as reported in other dicotyledons. Progenies (T_1 generation) derived from primary transformant of 17 lines were segreagated with a 3 resistant:1 sensitive ratio in medium containing hygromycin and bialaphos. Stable integration of Bar gene into chromosomal DNA was proven by Southern blot analysis of genomic DNA isolated from T_2 progenies. Transgenic plants (T_3) grown in the field were resistant to bialaphos (Basta) at a dosage lethal to wild type plants.
