주영하,유태종,유주현,Chu, Young-Ha,Yu, Tai-Jong,Yu, Ju-Hyun 한국식품과학회 1975 한국식품과학회지 Vol.7 No.2

산막효모(産膜酵母)가 형성(形成)된 제품(製品)간장에서 산막생성(産膜生成)과 발효력(醱酵力)이 강(强)한 효모(酵母)를 분리(分離)하고 Lodder 들의 효모분류법(酵母分類法)에 따라 Saccharomyces rouxii (film forming yeast)로 동정(同定)하였으며 이효모(酵母)들의 발효현상(發酵現象) 및 생리적(生理的) 특성(特性)은 다음과 같았다. 1. 간장발효실험(發酵實驗)에서 간장중(中)에 함유(含有)된 당분(糖分)을 모두 발효(醱酵)시켜 고형분(固形分)은 감소(減少)되고 총질소(總窒素), 색도(色度)를 감소(減少)시켰다. 2. 방부력실험(防腐力實驗)에서 butylparaben 은 60 ppm, sodium benzoate 800 ppm, sodium propionate 2,400 ppm, menadione 165 ppm, potassium sorbate 500 ppm, sorbic acid 300 ppm 이상(以上)의 농도(濃度)에서 이들균(菌)의 생육(生育)이 억제(抑制)되었고 에칠알콜 첨가구(添加區)에서는 3%에서도 방부력(防腐力)이 없었다. 3. 2%(w/v) glucose yeast extract peptone 배지(培地)에서 이들균(菌)의 최적식고농도(最適食?濃度)는 5%, 최적배양온도(最適培養溫度)는 $30^{\circ}C$, 사멸온도(死滅溫度)는 NO-1, 3균(菌)이 $62^{\circ}C$ (10분간(分間) 살균처리(殺菌處理)), NO-2, 4균(菌)이 $65^{\circ}C$ 이었으며 최적(最適) pH 는 5. 0이었다. 4. Gas chromatography 에 의(依)한 피막(皮膜)간장의 향기성분(香氣成分)은 표준(標準)간장에 비(比)해 저비점(低沸點)의 물질(物質)이 많으며 이 성분(成分)들이 간장의 풍미열화(風味劣化)에 기여(寄與)하는 것으로 생각되었다. This study was conducted (1) to isolate the film-forming yeast from the commercially available soy sauce, (2) to identify the state of soy sauce fermentation by the use of yeasts, (3) to confirm characteristics of yeasts. The result were as follows. 1. These yeast strains in the soy sauce fermentation test showed full fermentation of whole sugar content, reduction of the pure extract and relative reduction in total nitrogen. Soy sauce color was somehow faded to lower the stability of soy sauce. 2. In anti-fungal activity test butylparaben at a higher level 60 ppm., sodium propionate 2,400 ppm, sodium benzoate 800 ppm., menadion 165 ppm, showed their anti-fungal effect, while alcohol did not show the effect in the 3% additive group. 3. The optimum sodium chloride concentration for these strains in the 2% G.Y.P. medium was 5% and optimum temperature was $30^{\circ}C$. The extinction temperature was $62^{\circ}C$ for strain No-1 and No-3, and was $65^{\circ}C$ for No-2 and No-4. 4. The film-forming soy sauce turned out in the gas chromatogram to possess much flavor of low boiling point as compared with the standard. These flavors were considered due to flavor spoilage of the soy sauce. 5. These isolated yeasts were identified Saccharomyces rouxii (film-forming yeast) in the Lodder's taxanomic study.

주영하 ( Ju Young-ha ),정원미 ( Jung Won-mi ),안소영 ( An So-young ),선미정 ( Seon Mi-jeong ) 한국청소년학회 2023 청소년학연구 Vol.30 No.5

이 연구의 목적은 장애 청소년과 가족을 대상으로 4차 산업혁명의 대표적 기술인 소셜 로봇과 사물인터넷 기술을 실제 활용한 경험을 탐색하는 것이다. 이를 위하여 소셜 로봇과 사물인터넷을 실제 활용한 경험이 있는 장애 청소년 8명과 가족 5명을 연구참여자로 하여 초점집단면담을 실시하였다. 연구 결과 장애 청소년은 “새로운 세상”,“나에게 찾아온 변화”, “아쉬움과 기대”라는 총 3개의 주제, 6개의 하위범주, 11개의 의미 있는 개념들을 도출하였으며, 장애 청소년의 가족은 “장애 청소년에게 찾아온 변화”, “장애인 가족 삶의 질 향상”, “편리하지만 아쉬운 IT 세상”, “앞으로 더 기대됨”이라는 4개의 주제, 9개의 하위범주, 17개의 의미 있는 개념들을 도출하였다. 이를 통해 “새로운 변화와 성장의 문턱을 넘는 경험이지만 아직은 장애 특성을 반영하기에는 부족한 기술”이라는 종합 주제를 도출하였다. 이러한 연구 결과를 바탕으로 장애 청소년과 가족의 IT 접근성 강화를 위한 함의를 제언하였다. This study investigated how children with disabilities experience social robots and the Internet of Things (IoT), technologies representative of the 4th industrial revolution. We conducted focus group interviews with eight children with disabilities and five family members who had experience using social robots and IoT. Resultingly, we derived three themes, six subcategories, and 11 meaningful concepts by interviewing the children. The three themes were a new world”, “changes that happened to me” and “regret and expectation. By interviewing the family member, four themes, nine subcategories, and 17 meaningful concepts were derived. The four themes were “changes that happened to children with disabilities”, “improved the quality of life of the families”, “convenient but not satisfying IT world” and “Looking forward to more.” Based on these interviews, we derived a comprehensive theme that “using the technologies is the experience of crossing the threshold of new change and growth for children with disabilities and their families, but the technologies do not fully reflect the characteristics of people with disabilities .” Based on the results obtained, this study suggests strengthening the access of children with disabilities and their families to Information Technology.

주영하 ( Young Ha Ju ),정익중 ( Ick Joong Chung ) 한국법정책학회 2016 법과 정책연구 Vol.16 No.1

본 연구의 목적은 한일 공공후견사업을 사회복지정책 분석틀에 근거하여 비교하여, 우리나라 발달장애인 공공후견사업이 더 나은 방향으로 나아가도록 시사점을 제시하는 것이다. 본 연구의 연구결과는 다음과 같다. 첫째, 한국은 만 19세 이상 발달장애인이 대상이지만, 일본은 치매 노인에서 지적장애인, 정신장애인까지 확대하여 시행하고 있다. 둘째, 한국은 전국사업으로 신청비용과 보수비용이 일정하지만, 일본은 시정촌에 따라 신청비용과 보수비용에 차이가 있다. 셋째, 한국은 후견법인이 없고 네트워크를 형성 중에 있지만, 일본은 후견법인이 있고 노인과 장애인 관련기관의 전달체계가 유기적으로 네트워크를 형성하고 있다. 마지막으로 본 연구는 저소득 치매노인 대상자의 확대, 후견인 활동비용의 추가 지원, 법인후견 등 다양한 전달체계와 전문적 네트워크 형성, 후견 수요자 발굴을 위한 홍보의 강화 등의 정책적 함의를 제시하였다. The purpose of this study is to propose implications for a better direction of the public services of the adult guardianship for people with developmental disabilities by making a comparison between the public guardianship services of Korea and Japan based on social welfare policy analysis framework. The results of the study are as follows: First, Korea targets adults with developmental disabilities who are nineteen years or older whereas Japan is implementing the services within a larger frame which includes elderly people with dementia, people with intellectual disability, and people with mentally disability. Second, while the application cost and the maintenance cost in Korea are the same in every municipality owing to the national-level services, there are differences in the costs depending on municipalities in Japan. Third, in the case of Japan, there is a corporate guardianship for guardianship and the delivery system of institutions related to elderly citizens and the disabled is a closely formed network. On the other hand, Korea does not have a corporate guardianship but has just started to form delivery system. Lastly, this study proposed these policy implications: expansion of subjects regarding the elderly with dementia, additional support in rewards of guardian, formation of a variety of delivery systems and a specialized network such as a corporate body for guardianship, and consolidation of public relations to find out guardianship consumers.

주영하(Ju, Young Ha),정익중(Chung, Ick Joong) 경성대학교 사회과학연구소 2016 社會科學硏究 Vol.32 No.1

본 연구의 목적은 발달장애인이 차별을 경험함으로써 낮아지는 자아존중감을 완화시키기 위해서 생활만족도의 매개효과를 검증하고, 이 변수들 간의 관계에서 근로소득의 조절효과를 검증하는 것이다. 본 연구는 구조방정식모형을 활용하여 장애인고용패널(Panel Survey of Employment for the Disabled) 제5차년도(2012년) 자료를 분석하였다. 분석대상은 총 213명의 발달장애인(지적장애인 189명과 자폐성장애인 24명)이다. 본 연구의 연구결과는 다음과 같다. 첫째, 발달장애인이 겪는 차별경험은 자아존중감에 부정적인 영향을 미쳤다. 둘째, 발달장애인이 겪는 차별경험이 자아존중감에 미치는 영향은 생활만족도에 의해 완전매개 됨을 확인하였다. 셋째, 다중집단 분석결과, 이 변수들 간의 관계는 생활만족도가 자아존중감에 미치는 경로가 근로소득 유무에 따라 달라지는 것으로 나타났다. 마지막으로 본 연구는 사회적 인식의 변화와 프로그램 개발, 근로소득을 위한 지원이라는 실천적 함의를 제시하였다. The purpose of this study was to examine the mediating effect of life satisfaction in order to mitigate the lowered self-esteem when people with developmental disability experience discrimination, and to verify the moderating effect of earned income within this relationship. The fifth wave data of Panel Survey of Employment for the Disabled were analyzed by structural equation modeling. The study sample was a total of 213 people with developmental disability. The results of this study were as follows. First, the discrimination experiences of people with developmental disability have a negative impact on self-esteem. Second, the impact of the discrimination experiences of people with developmental disability on self-esteem was fully mediated by life satisfaction. Third, in the multiple group analysis, the relationship among variables varied depending on the presence or absence of the earned income. Specifically, the effect of life satisfaction of people with developmental disability on the self-esteem among the group with no earned income was higher than that among the group with earned income. Based on these results, this study suggested practice and policy implications for people with developmental disability.

Job satisfaction and life satisfaction have been extensively studied, but discussions regarding the influence between the two variables are mixed. This study aimed to verify the reciprocal relationship between job satisfaction and life satisfaction in people with disabilities. An autoregressive cross-lagged model was applied to analyze the longitudinal data from the first to the third year of the 2nd Wave Panel Survey of Employment for the Disabled, which was conducted by the Korea Employment Agency for the Disabled. The study results were as follows: First, job satisfaction and life satisfaction of people with disabilities were found to be stable over time. This means that the relative position of job satisfaction and life satisfaction did not change over time. Second, it was found that job satisfaction had a significant effect on life satisfaction and life satisfaction also had a significant effect on job satisfaction of people with disabilities after one year. Third, it was confirmed that the job satisfaction and life satisfaction of employed people with disabilities have a reciprocal relationship with each other and that the influence of life satisfaction on job satisfaction is stronger than the influence in the opposite direction. Based on these findings, the implications for improving job satisfaction and life satisfaction in people with disabilities were discussed.

KCI와 WoC에서 키워드를 추출하였고, 추출된 키워드들의 정제 작업 이후 KCI에서는 문헌 빈도수 3회 이상의 키워드 71개, WoC에서는 문헌 빈도수 11회 이상의 키워드 88개를 최종분석 키워드로 선정하였다. 이 연구의 결과는 다음과 같다. 첫째, 네트워크 분석에서 패스파인더 네트워크(PFNET)와 병렬최근접이웃클러스터링(PNNC)을 통해 형성된 군집은 국내 15군집과 국외 20군집으로 나타났다. 둘째, 발달장애 관련 연구는 KCI 주제 분야 분류를 통해 사회복지, 특수교육, 평생교육 분야에서 연구가 이루어짐을 알 수 있었고, WoC 주제 분야 분류를 통해 사회복지, 교육, 과학기술 및 IT 분야에서 활발하게 연구가 이루어지는 것을 확인하였다. 셋째, 국내외 발달장애 분야의 공통적 핵심 주제어는‘교육’,‘행동’,‘가족’ 및 ‘참여’로 나타났다. 넷째, 국내는 성 및 평생교육 군집이, 국외는 과학기술 및 IT 군집이 출현하는 것을 확인하였다. The aim of this study is to compare domestic and international research trends in the field of developmental disability by conducting the keyword network analysis on domestic and international literature collected on the subject of developmental disability. The databases used for retrieving literature to be analyzed were Korea Citation Index (KCI) for domestic literature and Web of Science Core Collection (WoC) for overseas literature. In order to retrieve literature in the field of developmental disability, 발달장애 (developmental disability) was used as the keyword in research title on KCI, and developmental disability was used as the keyword in topic on WoC. The search period for published papers was set from 2014 to 2018. As a result of the search, 393 cases of domestic literature and 5,876 cases of overseas literature were selected for the final analysis. Keywords were extracted from both KCI and WoC literature. After filtering the extracted keywords, 71 keywords showing 3 or more occurrence frequency in KCI papers and 88 keywords showing 11 or more occurrence frequency in WoC papers were selected for final analysis. The results of the keyword network analysis were as follows. First, in the network analysis, 15 clusters for domestics papers and 20 clusters for overseas papers were formed through Pathfinder Network and Parallel Nearest Neighbor Clustering. Second, it was found through KCI subject field classification that domestic research related to developmental disability is conducted in fields such as social welfare, special education, and lifelong education. It was also found through WoC subject field classification that overseas research related to developmental disability is actively conducted in fields such as social welfare, education, science and technology and information technology. Third, core keywords commonly found in domestic and overseas research in the field of developmental disability were education , behavior , family and participation . Fourth, it was found that the emerging cluster in the domestic research trends in developmental disability is the gender and lifelong education cluster, while the emerging cluster in the overseas research trends is the science & technology and IT cluster.

주영하 ( Ju Young-ha ),박미진 ( Park Mi-jin ),김기룡 ( Kim Ki-ryong ) 한국특수아동학회 2021 특수아동교육연구 Vol.23 No.4

연구목적: 이 연구의 목적은 발달장애인과 가족 간 발달장애인 평생교육 프로그램 이용 의향에 따라 구분되는 잠재계층 유형을 확인하고, 각 유형과 발달장애인평생교육시설 이용 만족도 간의 관계를 탐색하는 것이다. 연구방법: 장애인 평생교육 프로그램 이용 의향을 파악하기 위한 문항 등으로 구성된 설문지를 활용하여 서울시에 위치한 발달장애인평생교육시설을 이용하고 있는 발달장애인 222명과 가족 256명을 대상으로 조사를 실시하였으며, 잠재계층분석을 수행하였다. 연구결과: 첫째, 발달장애인의 장애인 평생교육 프로그램 이용 의향 잠재계층 유형은 4개로 분류되었으며, 그 특성에 따라 ‘문해문화예술인문교양중심형’, ‘직업인문교양중심형’, ‘문화예술시민참여중심형’, ‘문해직업문화예술중심형’으로 명명하였다. 둘째, 발달장애인 가족의 장애인 평생교육 프로그램 이용 의향 잠재계층 유형은 3개로 분류되었으며, 그 특성에 따라 ‘문화예술중심형’, ‘직업인문교양시민참여탐색형’, ‘문해중심형’으로 명명하였다. 셋째, 발달장애인의 발달장애인평생교육시설 이용 만족도는 ‘문해문화예술인문교양중심형’이 가장 높게 나타났다. 결론: 발달장애인과 가족은 장애인 평생교육 프로그램 이용 의향에서 잠재계층 간 차이가 있었다. 이에 장애인 평생교육 프로그램은 발달장애인이 원하는 욕구를 중심으로 맞춤형으로 구성되어야 하고, 장애인 평생교육 프로그램이 다차원적으로 개발 운영되어야 할 것이다. Purpose: This study was conducted to identify latent classes that were distinguished by the intention to use lifelong education programs for people with disabilities, and to identify satisfaction affecting each class, focusing on the differences in perception between the people with developmental disabilities and their families. Method: The study conducted a survey on 222 people with developmental disabilities and 256 parents who were using the lifelong education facilities for the people with developmental disabilities located in Seoul using a questionnaire consisting of questions to understand the intention to use the lifelong education programs for the people with disabilities. The study performed latent class analysis. Results: First, the analysis identified four latent classes of people with developmental disabilities. The study were named ‘Literacy Arts Culture-centered type’, ‘Job Culture-centered type’, ‘Arts Citizen-centered type’, and ‘Literacy Job Arts-centered type’. Second, the analysis identified three latent classes of families of children with developmental disabilities. The study were named ‘Art-centered type’, ‘Exploration type’, and ‘Literacy-centered type’. Third, the satisfaction level of people with developmental disabilities was the highest in 'Literacy Job Arts-centered type'. Conclusion: There was a difference in the intention to use the lifelong education programs for people with disabilities between the people with developmental disabilities and their families. The lifelong education programs for people with disabilities should be structured around the needs of people with developmental disabilities. As well, lifelong education programs for people with disabilities should be developed and operated in multiple dimensions.

민자영(ja young min),김기룡(Ki Ryong Kim),황지현(Ju Hyun Hwang),주영하(Young-Ha Ju) 한국장애인복지학회 2024 한국장애인복지학 Vol.63 No.-

이 연구에서는 중고령 발달장애인의 수단적 일상생활 능력을 잠재유형으로 분류하고 중고령 발달장애인의 특성과 지원 요구를 탐색하고자 하였다. 이를 위해 2023년 ‘발달장애인 일과 삶 실태조사’의 데이터를 활용하여 잠재 프로파일 분석 방법으로 중고령(40세 이상) 발달장애인과 청장년(40세 미만) 발달장애인의 수단적 일상생활 능력에 대한 잠재유형을 분류하고 그 차이를 비교하였다. 연구 결과 중고령 발달장애인의 수단적 일상생활 능력 잠재유형은 ‘높은 일상생활 능력 유형(53.3%)’, ‘낮은 일상생활 능력 유형(46.7%)’으로 분류되었다. 둘째, 청장년 발달장애인 수단적 일상생활 능력 잠재유형은 ‘높은 일상생활 능력 유형(38.1%)’, ‘낮은 일상생활 능력 유형(33.1%)’, ‘중간 일상생활 능력 유형(28.8%)’으로 분류되었다. 중고령 발달장애인은 청장년 발달장애인보다 ‘낮은 일상생활 능력 유형’의 비율이 더 높게 나타났고 수단적 일상생활 능력이 낮은 일상생활 능력을 갖고 있는 중고령 발달장애인이 청장년 발달장애인보다 일상생활에서 더 많은 도움을 필요로 하고 있음을 시사하고 있다. 이와 같은 연구 결과를 바탕으로 중고령 발달장애인의 지원 방안을 제언하였다. This study was to classify the instrumental activies of daily living(IADL) skills of middle-aged and older people with developmental disabilities into latent types and explore the characteristics and support needs of middle-aged and older people with developmental disabilities. Data were collected from the 2023 ‘Survey on the Work and Life of Persons with Developmental Disabilities’ to analyze the latent profile to determine the latent types of IADL of middle-aged and older (over 40 years old) and young (under 40 years old) people with developmental disabilities. As a result of the study, the latent types of IADL of middle-aged and older people with developmental disabilities were classified into ‘high daily living ability type (53.3%)’ and ‘low daily living ability type (46.7%).’ Second, the latent types of IADL for young people with developmental disabilities are classified into ‘high daily living ability type (38.1%)’, ‘low daily living ability type (33.1%)’, and ‘medium daily living ability type (28.8%)’. Middle-aged and older people with developmental disabilities showed a higher rate of 'low daily living ability type' than young people with developmental disabilities, and middle-aged and older people with developmental disabilities who had low IADL showed more skills in daily life than young people with developmental disabilities. It suggests that you need help. Based on these research results, support measures for middle-aged and older people with developmental disabilities were proposed.
