본 연구에서는 거베라 형질전환 기초기술개발을 위한 연구를 수행하였다. 경남원예화훼시험장에서 육성된 국내 거베라 18품종 중, Agrobacferium 감염에 순응적인 품종을 선발하기 위하여 18개의 국내 거베라 품종을 스크린하여 011, 016, GM023 등 12개의 순응형 계통을 스크린 하였으며 효율적인 형질전환을 위한 제균 항생제로는 cefotaxime이 선택되었다. 더 많은 캘러스 유도를 위한 전처리 배지의 호르몬 농도는 BA 2 ppm, Zeatin 2 ppm, IAA 0.2 ppm (2 x media)이 효율적이었고 재분화 배지의 호르몬 농도도 전처리 배지 호르몬의 농도와 동일하게 BA 2 ppm, Zeatin 2 ppm, IAA 0.2 ppm (2 x media)에서 효율적이었으나 GUS 발현에는 다른 차이가 없었다. 고효율 형질전환 체계 확립을 위하여 네 가지 다른 전처리 기간 처리와 두 가지 다른 Agrobacterium tumerfaciens 사용, 두 가지 다른 공배양 기간을 처리한 결과 전처리 하지 않은 엽병과 엽신을 LBA4404 Agrobacterium tumerfaciens을 사용하여 5일 간 공배양 기간을 가졌을 때와 dipping 처리하여 접종한 엽병과 엽신에서 높은 GUS 발현빈도를 나타냈다. Gerber (Gerbera hybrida) is a valuable ornamental species grown as a potted plant and cut flowers. However, genetic variability within the gerbera genus is very limited. So it is absolutely needed to introduce and widen genetic resources into gerbera lines by genetic transformation. For the purpose, 18 Korean gerbera lines were screened to establish Agrobacterium-mediated genetic transformation procedure. In an experiment to select Korean gerbera lines which are amenable to Agrobacterium-inoculation, 12 lines turned out to be positive in Agrobacterium-inoculation. More callus were produced from BA 2ppm, Zeatin 2ppm, IAA 0.2ppm in pre-culture and regeneration medium (2X media) but there was no difference in the frequency of GUS expression rate. In another experiment to find out optimal condition for highly efficient Agrobacterium-inoculation, petiole and leaf explants have been treated with four different pre-culture periods, two different co-culture periods and two different Agrobacterium strains. As a result, high GUS expression has been showed from petiole and leaf explants treated no pre-culture period with LBA4404 Agrobacterium tumerfaciens, 5 day co-culture period and dipping treatment.

이혜영,최대균,최부병,박남수,Lee, Hye-Young,Choi, Dae-Gyun,Choi, Boo-Byung,Park, Nam-Soo 대한치과보철학회 1986 대한치과보철학회지 Vol.24 No.1

It is considered that etching solution or material itself of phosphoric ester cement will induce not a little pulpal irritation, if applied directly onto unsealed dentinal tubules. This study was designed to confirm above consideration by comparing two different conditions between $Ca(OH)_2$-based and non-$Ca(OH)_2$-based group. Posterior teeth of 15 male dogs were selected for this experiment. One experimental group was filled with cement after $Ca(OH)_2$-basing and enamel-etching, the other experimental group after enamel etching without $Ca(OH)_2$-basing. And both of two experimental groups were observed at 2 hours, 15 hours, 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks after filling. The findings reached to the following conclusions histologically. 1. In both groups, the damaged odontoblasts were atrophied and eventually disappeared. 2. In non-based group at early stage, odontoblasts were severely atrophied and defective areas were appeared between odontoblast cell layers. However, in based group, the odontoblasts were arranged slight irregularly. 3. In non-based group, a small number of undifferentiated cells below the odontoblast cell layers started to appear at 1 week after filling. However, in based group, the undifferentiated cells were appeared at 15 hours after filling. 4. In non-based group, formation of reparative dentin was not begun until late stage of experiment. However, in based group, formation of reparative dentin matrix was begun at 2 weeks after filling and very thickened reparative dentin was formed at 6 weeks after filling. 5. In odontoblast cell layers of both groups, dilated capillaries were observed. 6. Argyrophilic fibers were reticularly condensed in zone of Weil, and they were connected to the pulp tissue and dentin.

이혜영,곽승진,Lee, Hye-Young,Kwak, Seung-Jin 한국문헌정보학회 2007 한국문헌정보학회지 Vol.41 No.2

The purpose of this study is to design the metadata for sharing and efficiently using the informations of Earth Observations in Korea. Recently the GEO(Group on Earth Observations) has been starting to manage all nation's informations in a way that benefits the environment as well as humanity by taking a pulse of the plants. For that reason, we have to construct the infra-system to manage and integrate the 12 social benefit areas in Korea; disaster, health, energy, climate, water, biodiversity, agriculture, forest, ocean, space information and geographical information system(GIS). But these informations have only been managed with varied metadatas in each area of observation, and then it is difficult to integrate varied informations. In this study, we solve the problem with meta-metadata. 본 연구는 지구 관측자료 공유 및 효율적 활용을 위한 통합 메타데이터를 설계하는 것이다. 최근 정부 간 조직으로 구축된 GEO(Group on Earth Observations)는 지구전반에 걸쳐 지속적으로 관측되는 자료를 활용하여 인류의 이익을 최대 창출하기 위해 노력하고 있다. 이러한 세계적 흐름에 따라 국내에서 관측되는 지구 관측자료 즉, 재해, 보건의료, 에너지자원, 기후, 수자원, 기상 생태계/생물다양성, 농업, 산림, 해양, 우주, 국토공간정보 등 12개 분야의 관측자료를 통합 및 활용하기 위한 인프라 구축이 반드시 필요하다. 현재 지구관측자료는 관측분야별로 개별적인 메타데이터를 관리하고 있을 뿐 메타데이터를 통합관리하지 못하고 있다. 국내 지구 관측자료의 관측분야와 관측요소별 다양하고 상이한 메타데이터로 인한 통합메타데이터의 설계 어려움을 메타-메타데이터를 이용하여 개발하였다.

Purpose: The purpose of this qualitative study was to understand the application of clinical reasoning throughout clinical and therapeutic knowledge of clinical pediatric physical therapists under physician prescriptions. Methods: Purposive sampling techniques were used in selection of nine clinical pediatric physical therapists in South Korea. Open and semi structured interviews were conducted, and were thoroughly examined and reviewed, followed by analysis of the clinical reasoning portion. Results: Pediatric physical therapists have been influenced by information gathering, physical function and evaluation of their patients, hypothesis-orientation, and re-evaluation and self-monitoring. Novice physical therapists were more dependent on physician prescriptions and parent's hope than the result of their own evaluation and critical pathway. Middle experienced pediatric physical therapists were more dependent on rapport with children and their parents. Highly experienced pediatric physical therapists were more reliant on hypothesis-orientation and self-monitoring. As reports on clinical experience of pediatric physical therapists have accumulated, clinical reasoning of pediatric physical therapists has been influenced by their experience, such as education, clinical pathology conference, their own clinical experience and rapport with patients and their parents than physicians' prescriptions. Conclusion: The findings of the current study are generally consistent with existing research on clinical reasoning. The results of the current study may be used by educators for enhancement of clinical reasoning abilities and knowledge of students or novices as well as development of a guide for use by suitable novices or students, and could provide important information for use in physical therapy practice and research.

Purpose: The goal of this study was to analyze the degree of stress and methods of coping with stress in mothers of cerebral palsied children and to provide a basic resource for the development of policies to improve the mental health of mothers with cerebral palsied children. Methods: 85 mothers with cerebral palsied children and 77 mothers of normal children completed a self-administered questionnaire that evaluated the degree of stress and methods of coping with stress. Cronbach's ${\alpha}$ score was used to determine the internal consistency of the acquired data and the discriminated validity was estimated by Pearson's correlation coefficient. Independent t-tests were conducted to compare the degree of stress and method of coping with stress between mothers of cerebral palsied children and mothers of normal children and one-way ANOVA was performed to analyze the effect of generalized characteristics on stress in mothers of cerebral palsied children. Results: The degree of stress in terms of anxiety response and roles as mother for mothers with cerebral palsied children was higher than mothers with normal children. However, there was no significant difference between two group in regards to the methods of coping with stress during a stressful episode. The degree of stress for mothers with cerebral palsied children was greater when the child was younger. Conclusion: Mothers of cerebral palsied children had higher stress than that of mothers with normal children and felt more stress when their child was younger. Therefore, these results suggest that health-based policies should be developed to improve the mental health of mothers with cerebral palsied children.

많은 도서관은 한정된 자원을 극복하고 이용자의 정보요구를 충족시키기 위하여 상호대차서비스를 활용한다. 상호대차서비스는 도서관 서비스의 소유 소장의 개념에서 공유 접근의 개념으로 변화를 말하는 것으로, 상호대차서비스 평가 및 그 필요성을 재고할 필요가 있다. K대학은 단행본 중심의 캠퍼스 상호대차서비스는 오랫동안 제공하였는데, 2003년부터 온라인서비스를 제공하는 등의 노력을 지속적으로 하였다. 본 연구는 상호대차서비스의 전산화가 서비스에 미치는 영향을 분석하기 위한 것으로 9년간의 서비스운영 실적을 비교분석하였다.시스템 발전 단계에 따라 상호대차 신청과 도서 대출 건수가 급격히 증가하는 것을 볼 수 있었다. 또한 서울캠퍼스 소속 이용자의 상호대차신청건수가 2001년 전체 도서신청건수 중 12%이었던 것이 2008년 무려 75%까지 상승한 것을 확인할 수 있었다. 상호대차 처리시간도 2004년의 17% 수준으로 떨어지는 등 많은 개선 결과를 보였다. Generally, we used to provide ILL to users for overcoming the limited resource and satisfying user's desires for information. ILL makes library service's paradigm change from ownership to sharing. K-university Library has been providing Campus inter-library loan as ILL to users for long time and continually trying to improve the service's quality. This case study is to analysis the performance of campus inter-library loan in the past 9 years. As the related automation system was developed and upgraded, the service requests have been increasing annually. Campus inter-library loan requests were 12% of total book requests in 2001, and then were 75% of total book requests in 2008. The transaction time was reduced until 17% of 2004.

Purpose: Respiratory is an essential vital component for conservation of life in human, which is controlled by respiratory muscles and its related neuromuscular regulation. The purpose of this study is to assess lung capacity and respiratory pressure in healthy children, and to investigate relationship and predictability between respiratory pressure and other related respiratory functions. Methods: A total of 31 healthy children were recruited for this study. Demographic information and respiratory related factors were assessed in terms of body surface area (BSA), chest mobility, lung capacity, and respiratory pressure. Correlation between respiratory pressure and the rested variables was analyzed, and multiple regression using the stepwise method was performed for prediction of respiratory muscle strength, in terms of respiratory pressure as the dependent variable, and demographic and other respiratory variables as the independent variable. Results: According to the results of correlation analysis, respiratory pressure showed significant correlation with age (r=0.62, p<0.01), BSA (r=0.80, p<0.01), FVC (r=0.80, p<0.01), and FEV1 (r=0.70, p<0.01). In results of multiple regression analysis using the backward elimination method, BSA and FVC were included as significant factors of the predictable statistical model. The statistical model showed a significant explanation power of 71.8%. Conclusion: These findings suggest that respiratory pressure could be a valuable measurement tool for evaluation of respiratory function, because of significant relationship with physical characteristics and lung capacity, and that BSA and FVC could be possible predictable factors to explain the degree of respiratory pressure. These findings will provide useful information for clinical assessment and treatment in healthy children as well as those with pulmonary disease.

한국의 정책집행 사례에 대한 메타분석적 연구

이혜영(Lee, Hye Young),고효진(Ko, Hyo Jin) 서울행정학회 2015 한국사회와 행정연구 Vol.26 No.2

본 연구에서는 기존의 단일 사례 중심의 집행 연구들의 한계를 극복하기 위하여 기존 집행 연구들에 대하여 메타분석적 연구를 수행하였다. 이를 통해 정책집행 연구의 이론화 가능성을 탐색하고, 우리나라에서는 정책집행에 영향을 주는 요소는 무엇인지, 어떠한 특성을 찾을 수 있는지 등을 살펴보고자 하였다. 1990년대 이후 이루어진 우리나라의 집행연구 55개를 대상으로 분석하였으며, 이론적 논의 및 사례 연구를 바탕으로 정책내용요인, 추진방식 및 절차요인, 집행관료 및 조직요인, 조직 간 관계요인, 정책대상자 요인, 환경요인 측면에서 47개 세부 집행영향요인을 도출하였다. 분석결과, 세부 집행요인 중에서 빈도가 높아서 우리나라 집행 연구에서 특히 중요하게 나타난 것은 정책의 명확성, 일관성, 관료의 전문성 및 역량, 리더십, 예산 등의 집행 자원, 타조직과의 협업, 대상집단의 행태와 이해관계, 환경의 지지 요인 등이다. 또한 정책 유형이나 정부 수준에 따라 강조되는 집행 변수에 상대적으로 차이가 있다는 것을 확인할 수 있었다. 이러한 연구 결과를 통해 볼 때, 향후 정책집행 연구에서 정책의 일관성이나, 조직 간 협업의 문제, 정책대상자 특성에 대해 좀 더 관심을 가질 필요가 있다. 또한 본 연구 결과는 정책 설계시 집행 가능성을 높이기 위해 실제 실무자들이 고려할 점이 무엇인가에 대해 중요한 시사점을 제공해 준다. This study is based upon a meta-analysis of Korean policy implementation cases, in order to overcome a limitation of existing policy implementation studies: A focus on single case studies. The purpose of this study is to explore theory building possibilities for implementation research, and to investigate factors and characteristics which influenced policy implementation. A total of 55 articles, published in Korea from 1990 to 2015, were selected. Based on the theoretical and case surveys, 47 detailed factors are identified that can influence the policy implementation process. The analysis results are as follows: First, key high frequency factors are policy clarity, policy consistency, bureaucratic expertise, capacity and leadership, executive resources such as budget, collaboration among organizations, target group behavior and interest, and environmental support. Second, there were relative differences among significant variables according to policy type or level of government. Based on these results, policy consistency, collaboration among organizations, and target group characteristics need to be explored further in future implementation studies. Lastly, this study has important implications concerning the considerations of policy practitioners at the early-design stage in order to increase policy feasibility.
