담수환원(湛水還元)된 토양중(土壤中) 인산(燐酸)의 유효도증가 원인(原因)을 밝히기 위하여 $30^{\circ}C$에서 8주간(週間) 담수(湛水) 항온시킨 토양현탁액의 pH, pe, $Fe^{+{+}}$ 및 수용성인산간(水溶性燐酸間)의 관계를 조사(調査)한 결과(結果)는 다음과 같다. 1. 토양(土壤)의 환원정도(還元程度)는 vivianite가 형성(形成)될 수 있는 안정범위에 들었다. 2. 수용성(水溶性) $Fe^{+{+}}$의 농도(濃度)는 vivianite가 용해(溶解) 되었을 때 나올 수 있는 값보다 높았다. 3. pH-$Fe^{+{+}}$간(間)의 관계(關係)로 볼 때 수용성(水溶性) $Fe^{+{+}}$의 농도변화는 $FeCO_3$계(系)에서와 같은 양상으로 나타났다. 4. 수용성(水溶性)P의 농도(濃度)와 pH간(間)에는 일정(一定)한 관계가 없는 것으로 보아 이계(系)에서 수용성(水溶性)P의 농도(濃度)는 vivianite의 침전(沈澱)과 용해(溶解)에 의(依)하여 결정(決定)되는 것 같지는 않다. As an approach to the explanation of increased availability of phosphate in reduced wetland soils, the interrelationships among pH, pe, $Fe^{+{+}}$ and water soluble phosphate in reduced soil-water suspension was studied. 1. p.e value of soil incubated for 8 weeks at $30^{\circ}C$ under waterlogged condition was sufficiently low to allow the conversion of strengite to vivianite. 2. The concentration of water soluble $Fe^{+{+}}$ in this system was higher than that is allowable by the solubility of vivianite. 3. From the relationship between pH and the concentration of water soluble $Fe^{+{+}}$, the concentration of water soluble $Fe^{+{+}}$ could be determined with the solubility of $FeCO_3$. 4. No definite relationship between pH and water soluble P was recognized which implied that the concentration of water soluble P in this system could not determined with the solubility of vivianite.

화학적 보정약이 정상견의 도플러 심초음파에 미치는 영향

윤정희,Yoon, Jung-hee 대한수의학회 1998 大韓獸醫學會誌 Vol.38 No.2

Intracardiac velocities were determined and the wave-forms described for 4 flow areas of the normal canine heart following administration of chemical restraint drugs including xylazine HCl, ketamine HCl, and thiopental sodium using pulsed wave Doppler echocardiography. The result was that xylazine HCl and thiopental sodium reduced intracardiac flow velocities through mitral, tricuspid, aortic and pulmonary valves. It is also thought that precautions are required before using these drugs. Patterns of wave-forms had no changes between control and treatment groups. Doppler echocardiography allows the clinician to determine flow velocities across the different valves and within the various chambers of the heart. It is shown that establishing normal values and those related to chemical restraint administrations and knowing what influences them should allow the clinician to non-invasively diagnose a variety of pathological cardiac conditions.

윤정희 ( Jeong Hee Yoon ) 대한아동복지학회 2005 아동복지연구 Vol.3 No.3

이 연구는 정서조절에 어려움이 있는 아동을 대상으로 치료놀이를 실시한 사례이다. 정서를 적절하게 표현하고 조절하는 능력은 아동의 정서 발달은 물론 사회성 발달, 부적응 행동과도 관계가 있으며, 기본적으로 양육자와의 관계에서 상호작용의 영향을 받는다. 치료놀이는 아동의 정서적 수준과 욕구에 맞추고 부모-자녀의 긍정적인 상호작용을 돕는 접근으로 치료놀이를 통한 정서조절에 문제가 있는 아동의 변화 과정과 아동과 어머니의 상호작용 변화를 알아보았다. 아동은 9살 여아로 학교 또래 관계와 갈등 상황에서 부정적인 감정을 조절하지 못하고 공격성을 나타내었다. 총 27회기의 치료놀이가 매주 1회, 30분 동안 실시되었다. 동시에 어머니는 해석치료자와 모든 회기에 걸쳐서 지속적으로 관찰과 상담을 하였으며 어머니의 회기 참여도 이루어졌다. 치료놀이를 통하여 아동은 적절한 자기표현이 향상되었고 긍정적인 정서 행동이 증가하였다. 어머니는 아동의 감정을 수용하고 욕구를 인식하여 아동에게 반응하게 되었다. 또한 마샥 상호작용 방법(MIM)으로 평가한 결과, 아동과 어머니의 상호작용은 치료놀이 실시 전과 유의한 차이를 나타내어 조화롭게 변화하였다. 이와 같은 결과에서 개별적으로 아동에게 적합한 치료놀이의 원리를 적용한 활동과 함께 양육자의 치료놀이 참여로 인한 관계와 상호작용의 변화로 정서조절에 문제가 있는 아동에게 치료놀이는 효과가 있음을 알 수 있었다. The purpose of this study is to investigate the effect of theraplay on a child with problems in emotion regulation. The subject was a 9-year-old girl with a history of emotion regulation difficulty and aggressive behavior. Past studies have illustrated the significance of interaction a caregiver and a child on the child`s emotion development, however, the relationship between the child and her mother in this study was rather insecure. Theraplay is used to focus specifically on child`s emotional level and to promote positive parent-child interaction. In this study, 27 theraplay sessions were performed with once a week frequency. During the theraplay trial period, the mother received consultation from interpreting therapist and actively participated in theraplay sessions. The child showed noticeable improvement in her ability to regulate emotion and increasingly displayed positive emotion with each theraplay session. Additionally, the mother became more receptive to child`s emotional needs, and thereby developed attuned responsiveness. And the application of Marschak Interaction Method(MIM) showed significant improvement in the interaction between the child and her mother. Thus, this study supports that theraplay is an effective approach for children with problems in emotion regulation.

According to the growing importance of science and technology policy, investment in research and development (R&D) has been increased. In this context, a patent as one of outcome of firm s systematic R&D investment is the way to hold a dominant position in companies technology competitiveness and also to protect technology right. This study attempts to find the effects of input resources and intellectual property production activity on company value. It conducted empirical analysis based on 238 KOSDAQ-listed and medium-sized firms. Using the previous research, this study configurated research variables about activity of patent production, company value, and input of resources. Through these variables, it aims to know the effect of input of resources and activity of patent production on company value. First, the result of regression analysis shows that R&D cost has the positive effect on a patent production and sales promotion cost positively affects on the registration of the trademark. Second, the output of regression analysis indicates that a patent has the positive effect on company value but a trademark has not. With regard to the input of resources, R&D cost has the influence on company value but sales promotion cost has not. This study attempts to find the effectiveness of company s intellectual property registration on its value and suggests a way that the systematic R&D investment contributes the growth of company value.

다문화 가정 영유아의 스마트 기기 사용실태 및 어머니 인식

윤정희(Jung-Hee, Yoon),이하원(Ha-Won, Lee) 한국다문화복지학회 2020 복지와 문화다양성연구 Vol.2 No.1

본 연구는 다문화 가정 영유아의 스마트 기기 사용실태 및 어머니의 인식을 조사하는 것을 목적으로 한다. 이에 다문화 가정이 비교적 많이 분포되어 있는 충남 및 경기도에 위치한 다문화 가정 어머니 총 108명을 대상으로 설문지 조사를 실시하였다. 설문지는 이원석, 서영화(2012)의 ‘유아와 부모의 스마트 사용실태’와 강연주(2014)의 ‘유아의 스마트 사용실태와 어머니 인식 척도’를 본 연구에 맞게 수정 보완하여 사용하였다. 수집된 자료는 SPSS 21.0을 사용하여 χ² 검증을 실시하였다. 결과는 첫째, 다문화 가정 영유아의 스마트 기기 첫 사용 시기는 13개월~24개월, 1회 사용시간은 20분 이하이며 매일 사용한다고 응답한 경우가 가장 많았다. 월평균 소득이 낮을수록 스마트 기기 사용시간이 높게 나타났고 사용법 및 사용결정은 어머니에게 의존하면서 함께 하는 것으로 나타났다. 또한, 재미와 학습적 요소를 위하여 스마트 기기를 사용하며 규칙을 정하고 사용한다고 응답한 경우가 가장 많았다. 둘째, 다문화 가정 영유아의 스마트 기기 사용에 대한 어머니의 인식은 스마트 기기의 필요성 유무에 유의한 차이가 없었으나 사용할 때는 읽기, 쓰기, 셈하기 등 교육적 기능에 목적을 두고 사용한다고 하였다. This study aims to investigate the use of smart devices by children from multicultural families and their mothers awareness. The survey was conducted on a total of 108 mothers from multicultural families in South Chungcheong Province and Gyeonggi Province, where multicultural families are relatively distributed. The questionnaire was supplemented by modifying ‘Smart Use Status of Infants and Parents’ from Lee Won-seok and Seo Young-hwa (2012) and ‘Mother Recognition Scale of Child Smart Use’ from Kang Yeon-ju (2014) for this study. The collected data were χ² validated using SPSS 21.0. The results were first, when children from multicultural families first use a smart device for 13 months to 24 months, and once use time is 20 minutes or less, and they said they use it every day. The lower the average monthly income, the higher the time spent using smart devices, and the more usage and decisions of use were found to be shared by relying on mothers. In addition, most respondents said that they use it for fun and learning elements and set rules and use them. Second, although there was no significant difference in the need for smart devices for multicultural children, the purpose of using them was to learn reading, writing, and counting.
