Backgronnd: Bronchial asthma is a complex genetic disorder. Although serum IgE level and bronchial hyperresponsiveness are well known to be under genetic control, the influence of genetic factors on basophil releasability has been seldom studied. Objective : The present study was carried out to investigate whether genetic factors may influence the basophil histamine releasability. Materials and methods : We studied 50 children, 32 with atopic asthma (AA) and 18 normal control (NC), and their parents. Suspensions of leukocytes were isolated and stimulated with Ca ionophore and anti-IgE antibody. Then, histamine in the supernatant was as-sayed by an automated fluorometric analyzer. Results : Among the probands, AA children had a significantly higher anti-IgE induced histamine release than NC children. In contrast, Ca ionophore-induced histamine release was similar between the two groups. Ca ionophore-induced or anti-IgE-induced histamine release was not significantly different between parents of AA children and those of NC children. However, the maximal histamine release by Ca ionophore in parents had a significant correlation with that of probands, whereas the values by anti-IgE were not correlated between probands and their parents. Conclusion : We confirmed that basophils from patients with atopic asthma are characterized by a specific increase in IgE-mediated histamine release. The significant correlation of Ca ionophore-induced maximal histamine release between children and their parents suggests that genetic factors may play an important role in the control of non-IgE-mediated relessability from basophils.

In this research, cubic zirconia is synthesized with a refined CaO from shells as a stabilizer through Skull melting method. The proper process time and concentration are defined by Hydration reaction to produce the refined CaO after two different treatments using 0.1 mol% of HCl respectively with Cockle shell. The highest purity of CaO is reached when the shell is immersed in 1 mol% HCl. In Hydration reaction step, the pure $Ca(OH)_2$ is produced at $45^{\circ}C$ for 24 hours. The highest purity of CaO is measured when the $Ca(OH)_2$ is treated by heat at $1200^{\circ}C$ for 5 hours. The single crystals are grown through Skull melting method by adding the different contents of the refined CaO from 10 mol% to 30 mol% into $ZrO_2$. The frequency of High-frequency oscillator used for Skull melting method is 3.4 MHz. The descending speed of the single crystal is 3 mm/hour. The grown length of the single crystal is 4 cm. As a result of this study, 15 mol% of CaO has the best crystallinity. 본 연구에서는 안정화제로, 패각으로부터 정제한 CaO를 사용하여 Skull melting법으로 큐빅 지르코니아를 성장시켰다. 꼬막 패각을 HCl을 0.1~1 mol%로 1차 처리한 후 수화반응을 거쳐 최적의 처리시간과 농도를 검토하였다. HCl을 1 mol%의 농도로 처리했을 때 가장 순도가 높았으며 수화반응시 $45^{\circ}C$의 온도로 24시간 동안 반응시킬 때 완전한 $Ca(OH)_2$ 를 얻을 수 있었다. $Ca(OH)_2$를 $1200^{\circ}C$에서 5시간 처리하였을 때 CaO의 순도가 가장 높게 측정되었다. 패각으로부터 얻어진 CaO를 $ZrO_2$에 첨가하여 함량을 10~30 mol% 로 변화시켜 Skull melting법으로 단결정을 성장시켰다. Skull melting법에 사용된 고주파 발진기의 주파수는 약 3.4 MHz이며 단결정의 하강속도는 시간당 3 mm로 4 cm 길이로 성장시켰다. 실험결과 CaO의 함량이 15 mol% 일 때 결정성이 가장 우수했다.

교사주도 학교개혁 운동의 등장

정진화 한국교육사회학회 2014 교육사회학연구 Vol.24 No.2

This study explores the background to and the processes underpinning the school reform movement that was initiated and led by teachers in the 2000s. This teacher-initiated school reform movement, which is referred to as the New School Movement, emerged from the cauldron of conflict and strife over key educational problems between the Korean government and the Korean Teachers and Education Workers Union (KTU), an alternative education movement in the 1990s. The KTU, which was founded in 1989, conducted the ChamGyoYuk (Cham-education) movement that brought qualitative changes in terms of teachers' teaching methods and classroom management. The union also achieved some measure of democratization within schools through the organization and creation of school governing bodies and the publication of school budgets and settlements of accounts; however, since the declaration of the 5ㆍ31 educational reform in 1995, the Korean government strengthened autonomy, accountability, school evaluation, and teacher evaluation and implemented a policy of school diversification. Due to these Neo-liberal policies, teachers were faced with a new series of frustrations and limitations to their educational activities in school. Since the KTU was legalized in 1999, the practice of ChamGyoYuk was left to individuals and it was criticized as being marginalized. Through this reflection, individual teachers who were interested in the ChamGyoYuk Movement initiated voluntary meetings, formed groups to seek an ideal school, and implemented the ideas in the field of school. In 2000, Namhansan elementary school was at a risk of being closed down; however, its teachers, parents, and members of the local community endeavored to save and to change the school. As a result, they initiated and implemented a student-centered curriculum, created a system of self-government for the school, and moved towards an eco-friendly school environment. This small school revival movement was later to grow into the New School Movement. Since the beginning, this movement slowly expanded through groups of teachers; however, growth of the movement accelerated by the openning up of the recruiting system for principal employment, which was initiated in 2007, and the development of “innovative schools”, which began in 2009. Furthermore, a variety of teachers, parents groups, and interested scholars engage in the movement via professional networking. This study suggests that the teacher-initiated movement, in which teachers have stood up for school reform, upgraded Korean education, and improved their own expertise and autonomy, is expected to be the first step to solve the current Korean educational problems. 이 연구는 2000년 이후 공교육 체제 안에서 일어나고 있는 교사주도 학교개혁 운동의 배경과 계기 및 전개과정을 분석한 것이다. 교사주도 학교개혁 운동은 조직적인 교사운동에 의해 공교육 체제 내의 학교를 개혁하려는 움직임으로 새로운학교운동이라고 불리고 있다. 새로운학교운동은 1990년대 한국 사회의 급격한 변동 속에서 새롭게 나타난 교육문제에 대한 정부의 대응과 전교조운동 및 대안교육 운동이 상호교섭과 충돌을 일으키는 가운데 등장하였다. 1989년 결성된 전교조의 참교육운동은 교과ㆍ주제ㆍ교육문화ㆍ학생활동 영역의 실천을 통해 학교 현장 교사들의 수업과 학급운영 방법에 변화를 가져왔다. 또 학교운영위원회 구성, 예결산 공개 등 학교 민주화를 상당부분 이루는 성과를 거두었다. 그러나 1995년 5ㆍ31 교육개혁안 발표 이후, 정부가 자율과 책무성을 강조하면서 단위학교 책임경영제를 도입하고, 학교평가와 교원평가 등 평가를 강화하며, 학교 다양화 정책을 실시하자 학교 간 격차와 입시경쟁이 치열해지는 현상이 나타났다. 이러한 일련의 신자유주의 정책들로 인해 학교 현장에서 교사들은 교육활동에 대한 좌절과 한계를 느끼게 되었으며, 1999년 전교조가 합법화된 이후 제도 개선 투쟁 위주로 사업을 진행하면서, 참교육 실천은 조합원 개인에게 맡겨지고 주변화되었다는 비판이 내부에서 제기되었다. 이러한 반성과 성찰을 통해 참교육 활동에 관심이 많은 교사들은 자발적 모임을 만들어 새로운 학교상(像)을 모색하고 실현해보고자 하였다. 2000년, 폐교 위기에 놓인 남한산초등학교를 교사, 학부모, 지역주민들이 함께 새로운 학교로 변화시킴으로써 작은 학교 살리기 운동은 새로운학교 만들기 운동으로 발전하였다. 남한산초등학교에서는 낡은 관행을 타파하고, 아이들을 중심에 두는 교육과정을 새롭게 구성하였으며, 교사ㆍ학생ㆍ학부모에 의한 학교자치가 이루어지고, 낡은 시설과 환경을 친환경적으로 바꾸는 변화가 일어났다. 이것을 공교육의 학교개혁 모델로 삼아 자발적인 교사모임을 통해 서서히 확산되던 새로운학교운동은 2007년 교장공모제 도입, 2009년 혁신학교 추진을 계기로 급속히 확산되고 있다. 최근에는 다양한 교원단체, 학부모단체, 교육연구소를 비롯한 학자, 교사, 학부모들이 네트워크 형태로 참여하고 있다. 이 연구는 그동안 개혁의 대상으로 여겨져 온 교사들이 개혁의 주체로 나서서 학교를 재구조화함으로써 교사운동을 한 차원 발전시키고, 교사들의 전문성과 자율성을 실현하고자 하는 교사주도 학교개혁 운동이 한국 교육문제 해결에 단초가 될 수 있을 것임을 시사한다.

수운과 샌델의 생명사상 연구 - 사상적 근친성의 모색 -

정진화 동학학회 2021 동학학보 Vol.- No.59

이 연구의 목적은 수운 최제우(水雲 崔濟愚)와 마이클 샌델(Michael Sandel)의 생명사상 에 대한 정치철학적 접근을 통해 사상적 근친성을 모색하고 동서양 사상의 통섭에 이르는데 있다. 수운 최제우가 수립한 ‘시천주(侍天主)’ 사상은 생명의 신성함과 역동적인 원리를 담고 있으며 샌델의 생명에 대한 인식과 태도는 제4차 산업혁명 시대의 생명공학 논쟁에 필요한 정치철학적 관점을 제시하고 있다. 이에 본 연구는 수운과 샌델의 생명사상을 연구하며 시공간적 한계를 넘어서는 사상적 근친성과 시사점을 모색해보고자 하였다. 연구내용은 다음과 같다. 첫째, 시천주 사상을 중심으로 수운의 생명사상과 그 의미를 살펴보고 둘째, 샌델의 공동체적 자아관과 생명의 기원에 대한 입장을 통해 생명에 대한 인식을 분석하며 셋째, 수운과 샌델의 사상적 근친성을 모색하고 시사점을 도출했다. 연구 내용을 검토한 결과 수운과 샌델의 생명사상은 시대적 상황과 논리 구조, 그리고 실천적 측면에서 차이점이 존재하지만 생명에 대한 도덕적 인식과 태도, 공동체적 관점, 그리고 만물에 대한 생명의 평등성을 강조하고 있다는 점에서 사상적 근친성을 갖고 있는 것으로 분석되었다. 이와 같은 연구는 현대 물질만능주의와 팬데믹 사태 속에서 생명에 대한 인식과 철학이 정치적 영역에서 얼마나 중요한 것인지 깨닫는 계기를 제공하며 현대사회가 생명에 대해 보다 바람직한 인식을 갖도록 하는데 중요한 이론적 기초를 제공할 수 있을 것이라 기대한다. The purpose of this study is to reach the consilience of Eastern and Western thoughts and explore the proximity of thoughts through research the life-thought of Su-un Choi Jeu and Michael Sandel based on a political philosophical approach. The idea of ‘Sichonju’ established by Su-un contains the sanctity and dynamic principle of life and Sandel’s recognition and attitude toward life suggests a political philosophical perspective necessary for the biotechnology debate in the era of the 4th industrial revolution. Therefore, this study researched Su-un and Sandel's life-thought and attempted to explore the proximity of thoughts and the implications beyond the temporal and spatial limits. The contents of study are as follows. First, I examined Su-un's life-thought and its meaning focusing on the idea of ‘Sichonju’, Second, I analyzed Sandel’s perception of life through communal self and position on the origin of life, Third, I explored the proximity of thoughts of Su-un and Sandel and derived implications. As a result of examining the contents of the study, it was found that Su-un and Sandel have differences in the historical circumstances, logical structure, and practical aspects, but have the proximity of thoughts in the following respects: emphasizing the moral perception and attitude toward life, the communal perspective, and the equality of all life. The study like this is expected that can set up an opportunity to realize how important the perception and philosophy of life are in modern materialism and pandemics, and can provide important theoretical basis to have a more desirable perception of life in the modern society.

Farmer’s age, technology adoption, and income: a case of the elderly-friendly technology in South Korea

정진화,김새봄 한국농업경제학회 2017 農業經濟硏究 Vol.58 No.3

This paper analyzes the effect of farmers’ age on the adoption of new agricultural technology and farm household income for the case of elderly-friendly new technology. Considering the endoge-neity of technology adoption, a two-stage estimation method was applied. Empirical analysis was conducted using the survey data of 265 strawberry farmers in South Korea. The empirical results confirm the significant income effect of technology adoption of farmers, but no income effect of farmers’ age once controlled for technology adoption. Farmers’ age also does not reduce the proba-bility of adopting new technology when controlled for the differences in technology acceptability, whereas farmers’ technology acceptability significantly raises the probability of technology adoption. Put differently, it is not farmers’ age but their technology acceptability level that determines the adoption of new technology and subsequently farm household income, at least in the case of eld-erly-friendly technology. It thus suggests that, facing the rapidly aging rural sectors, measures need to be taken to promote the development of elderly-friendly technology and enhance farmers’ technol-ogy acceptability level so that they are apt enough to adopt newly developed technology. Further research is called for to investigate whether this age-technology acceptability-technology adoption nexus holds for non-elderly-friendly technology.

영유아천명후 기관지천식으로의 이행에 미치는 부모이 아토피와 기관지과민성의 영향

정진화,김유영,김윤근,이명현,민경업,지영구,조상헌,고영률 대한알레르기학회 1998 천식 및 알레르기 Vol.18 No.4

Background: Many young children suffer from wheezing illness during viral respiratory infection, and some of them experience wheezing many years later and ultimately develop bronchial asthma. It is not clear whether atopy or bronchial hyperresponsiveness in the family is a significant risk factor for asthma in this clinical setting. Objective: To examine the genetic basis for the development of asthma after early childhood wheezing. Materials and methods : A measurement of serum total IgE concentration, skin prick test to common inhalant allergens, and methacholine bronchial provocation test were performed in 29 asthmatic children and their parents, and 22 non-asthmatic children with the past history of wheezing illness during the first three years of age and their parents. A questionnaire was performed to assess the presence of asthma and allergic rhinitis in the parents. Results : Positive skin test response to common inhalant allergens was more prevalent in asthmatics than in non-asthmatics(67.8% vs. 27.2%). Serum total IgE concentration was significantly higher in asthmatics than in non-asthmatics(geometric mean: 173 vs. 83 IU/ml). Positive skin test response to comman inhalant allergens was more prevalent in parents of asthmatics than in thoae of non-asthmatics(51.7% vs. 25.0%), but serum total IgE level was not different between the two groups(geometric mean: 132 vs. 120 IU/ml). Positive rate of methacholine bronchial provocation test, geometric mean of PC20-methacholine, and BR index were not different between the parents of asthmatics and non-asthmatics (18.1% vs. 13.9%; 164 vs. 180 mg/ml; 1.154 ±0.077 vs. 1.055 ±60.068, respectively). Conclusion : It is suggested that personal atopy is important in the development of asthma after early childhood wheezing, and parental atopy rather than bronchial hyperresponsiveness is a risk factor for the development of childhood asthma in this clinical setting.

동적 패널모형을 이용한 산업용 로봇 도입의 결정요인 분석

정진화,임동근 기술경영경제학회 2018 Journal of Technology Innovation Vol.26 No.4

In this paper, we analyze the determinants of the adoption of industrial robots using the data from 42 countries, and thereby examine the factors underlying the rapid expansion of industrial robots in Korea. To this end, the industrial robot data for the years 2001-2016 were drawn from the World Robotics dataset of the International Federation of Robotics (IFR). The explanatory variables included labor market environment variables and innovation capacity variables extracted from the dataset of the relevant international organizations. For data analysis, the Arellano-Bond dynamic panel analysis was performed to control for the endogeneity problem of some explanatory variables. The empirical results confirmed the exceptionally rapid expansion of industrial robots in Korea as compared to other countries, even when considering the national income level, employment cost, and innovation capacity. This phenomenon could be attributed to both the demand-side and supply-side factors. For one thing, changes in the labor market environment, such as an increase in employment costs, have led to an increase of the corporate demand for industrial robots. For another, the supply-side factors, such as an increase in the capital intensity and innovation capacity of companies, have also contributed to the widespread adoption of industrial robots 본 연구는 세계 42개국의 자료를 사용하여 산업용 로봇 도입의 결정요인을 분석하고, 한국에서 산업용 로봇이 빠르게 확산되고 있는 원인을 진단하였다. 산업용 로봇 변수는 국제로봇협회(IFR)의 2001년-2016년 「World Robotics: Industrial Robots」 자료를 사용하였다. 설명변수는 노동시장환경 변수와 혁신역량 변수를 포함하며, 관련 변수들은 해당 국제기관들의 자료에서 추출하였다. 실증분석에는 일부 설명변수의 내생성을 통제하기 위해 Arellano-Bond 동적 패널분석을 사용하였다. 분석결과, 한국은 소득수준이나 고용비용 및 혁신역량 등을 고려하더라도 다른 국가들에 비해 산업용 로봇 도입이 매우 빠르게 확대되어 온 것을 확인할 수 있었다. 이는 수요 측면과 공급 측면 모두에서 그 원인을 찾을 수 있다. 즉, 고용비용 증가 등의 노동시장환경 변화가 산업용 로봇 도입에 대한 기업 수요를 견인하였으며, 경제 전반의 자본집약도 증가와 기업의 혁신역량 증대와 같은 공급 측면 요인 또한 산업용 로봇의 도입을 촉진시켰다.
