치료도우미견을 활용한 동물매개치료가 아동의 자아존중감과 또래관계에 미치는 영향
강원국(Won-guk Kang),김옥진(Ok jin Kim) 한국콘텐츠학회 2021 한국콘텐츠학회논문지 Vol.21 No.6
본 연구는 치료도우미견을 활용한 동물매개치료가 아동의 자아존중감과 또래 관계에 어떠한 영향을 미치는지 살펴보고자 하였다. 연구대상은 I 시에 위치한 초등학교 저학년 아동 중 학교 사회복지사와 담임선생님의 추천을 받은 아동 20명이며, 실험집단 10명과 통제집단 10명을 선정하였다. 프로그램은 2019년 10월 1부터 12월 17일까지 동물매개치료 프로그램을 주 1회, 50분, 총 12회기를 실시하였다. 효과 검증을 위해 SPSS 20.0을 활용하여 실험집단과 통제집단에게 사전과 사후에 자아존중감, 또래관계 평정척도 측정을 실시하고 분석 하였다. 그 결과 첫째, 실험집단의 자아존중감 전체(Z=-2.75, p<.05), 가정에서의 자아존중감(Z=-2.02, p<.05), 학업적 자아존중감(Z=-2.06, p<.05)에서는 통계적으로 유의한 차이가 나타났다. 둘째, 실험집단의 또래관계 전체(Z=-3.83, p<.05), 하위 영역별로 주도성(Z=-2.68, p<.05), 협동공감(Z=-2.81, p<.05)에 유의미한 차이가 나타났다. 따라서 본 연구는 치료도우미견을 활용한 동물매개치료가 아동의 자아존중감과 또래관계에 긍정적인 영향을 준 것으로 확인이 되었다. In this study, we sought to investigate how animal-assisted therapy using therapy dogs affects the relationship between childrens self-esteem and age. The subjects of the study were 20 children in the lower grades of elementary school in I City who were recommended by a school social worker and their homeroom teacher, and 10 control groups of 10 experimental groups were selected. From October 1st to December 17th, 2019, the program conducted an animal-mediated treatment program once a week for 50 minutes for 12 sessions. Using SPSS 20.0 for verification, the experimental and control groups were analyzed by performing pre- and post-relationship calm scale measurements of self-esteem and age. As a result, first, the overall self-esteem of the experimental group (Z = -2.75, p<.05), the self-esteem at home (Z = -2.02, p<.05), and the academic self-esteem (Z = -2.06, p <.05) shows a statistically significant difference. Second, significant differences were shown in overall peer relationships(Z=-3.83, p<.05), scrupulosity(Z=-2.68, p<.05), and empathy(Z=-2.81, p<.05) in the experimental population. Therefore, in this study, it was confirmed that animal-assisted therapy using therapy dogs had a positive effect on the relationship between childrens self-esteem and age.

치료놀이를 적용한 동물매개치료가 장애아동 어머니의 양육스트레스와 양육효능감에 미치는 영향
강원국 ( Kang Won-guk ),오가영 ( Oh Ka-young ) 대구대학교 특수교육재활과학연구소 2021 특수교육재활과학연구 Vol.60 No.1
본 연구에서는 치료놀이를 적용한 동물매개치료가 어머니의 양육스트레스와 양육효능감에 미치는 영향에 대해 살펴보았다. 연구대상으로 J시에 위치한 A 심리상담센터의 만 9세부터 만 12세까지의 장애아동과 어머니 11쌍으로 실험집단 6쌍과 통제집단 5쌍으로 구성하였다. 실험집단에게 2020년 7월부터 10월까지 총 10회기, 회기당 40분을 모-아에게 실시하였다. 프로그램 효과검증을 위해 실험집단과 통제집단의 어머니에게 양육스트레스와 양육효능감 질문지를 사전과 사후에 실시하였다. SPSS 20.0을 활용하여 집단 내 사전과 사후를 비교한 결과는 다음과 같다. 첫째, 실험집단의 양육스트레스 전체와 하위영역인 양육관련 고민, 부모-아동 간 상호작용, 아동특성에 유의미한 차이가 나타났다. 둘째, 실험집단의 양육효능감 전체와 하위영역인 효능감과 불안감에 유의미한 차이가 나타났다. 하지만 통제집단의 양육스트레스와 양육효능감에서는 모두 유의미한 차이가 나타나지 않았다. 따라서 어머니는 장애 자녀와 함께 즐겁게 프로그램에 참여하고 프로그램 활동을 통해 양육기술을 익혀 양육스트레스가 감소하고 양육효능감이 향상되어 본 동물매개치료가 어머니의 양육스트레스와 양육효능감에 긍정적 영향을 미쳤음을 알 수 있었다. This study examined how the Animal-Assisted Therapy related to Therapy influenced the parenting stress and parenting self-efficacy of the mother. The study subjects were the disabled children whose ages are from ten to thirteen years old and their mothers in the eleven couples of the psychology consultation center in the J city. They were divided into the experiment group of the six couples and the control group of the five couples. To the experiment group of the disabled children with their mother, the program has been conducted for ten periods for forty minutes from July to October. To verify the effect of the program, the questionnaire of Parenting stress and Parenting Self-Efficacy was distributed to the mothers of the experiment group and control one before and after. In using SPSS20.0 the following is the comparison results of the pre and post in both groups. First, all of the Parenting Stress, including the anxiety related to nurturing, the interaction between mother and child, and the child's character, were decreased from the figure on the questionnaire in the experiment group. Second, in the control group, all of the Parenting Self-Efficacy with efficacy and anxiety were increased in the figure. After participating in the program with her disabled child in the delightful situation, when the mother learned the nurturing skills, the Parenting Stress was decreased but the Parenting Self-Efficacy was improved by the mother. Therefore, Animal-Assisted Therapy has a positive effect on the Parenting Stress and Parenting Self Efficacy of the mother.

쌍롤 박판 주조법으로 제조한 Ag-27.5%Cu-20.5%Zn-2.5%Mn-0.5%Ni 브레이징 합금의 미세조직 및 기계적 특성
김성준 ( Sung Jun Kim ),강원국 ( Won Guk Kang ),김문철 ( Mun Chul Kim ),김용찬 ( Yong Chan Kim ),이기안 ( Kee Ahn Lee ) 대한금속·재료학회 2009 대한금속·재료학회지 Vol.47 No.10
The suitability of twin roll strip casting for Ag-27.5%Cu-20.5%Zn-2.5%Mn-0.5%Ni brazing alloy (known as HS-49D) was examined in the present work and the mechanical properties and microstructure of the strip were also investigated. The effect of annealing heat treatment on the properties was also studied. The new manufacturing process has applications in the production of the brazing alloy. XRD and microstructural analyses of the Ag-27.5%Cu-20.5%Zn-2.5%Mn-0.5%Ni strip revealed a eutectic microstructure of an Ag-rich matrix (FCC) and a Cu-rich phase (FCC) regardless of heat treatment. The results of mechanical tests showed tensile strength of 434 MPa and 80% elongation for the twin roll casted strip. Tensile results showed decreasing strengths and increasing elongation with annealing heat treatment. Microstructural evolution and fractography were also investigated and related to the mechanical properties.

논문 : 딜라토미터를 이용한 STD11 공구강의 오스테나이징 및 템퍼링 열처리에 따른 치수 변화 이방성 연구
홍기정 ( Ki Jung Hong ),강원국 ( Won Guk Kang ),송진화 ( Jin Hwa Song ),정인상 ( In Sang Chung ),이기안 ( Kee Ahn Lee ) 대한금속재료학회 ( 구 대한금속학회 ) 2008 대한금속·재료학회지 Vol.46 No.12
Heat treatment is an important step for tool manufacture, but unavoidably generates dimensional distortion. This study investigated the continuous dimensional change and the anisotropic behavior of STD11 tool steel during austenitizing and tempering heat treatment especially using quenching dilatometer. Dilatometric results represented that the dimensional change along longitudinal direction was larger than that along transverse direction. Anisotropic phase transformation strain was produced in forged STD11 tool steel during heat treatment. Anisotropic dimensional change increased with increasing austenitizing temperature. After tempering, anisotropic distortion was partially reduced. FactSage thermodynamic equilibrium phase simulation and microstructural observation (FE-SEM, TEM) showed that large (7~80 μm) elongated M7C3 carbides could be formed along rolling direction. The resolution of elongated carbides during austenitizing was found to be related with the change of martensite transformation temperature after heat treatment. Anisotropic size change of STD11 tool steel was mainly attributed to large elongated carbides produced during rolling process. Using dilatometric and metallographic examination, the possible mechanism of the anisotropic size change was also discussed.
