즐거운 일터 만들기

정병탁 전남대학교 기업경영연구소 2005 經營情報 Vol.16 No.2

사장이 기분 좋게 웃으면서 직원들과 대화하고 나면 어딘지 모르게 사무실과 매장에 활기가 넘쳐난다. 리더가 웃어주면 조직이 유연 해 지고 즐거워진다. 학교에서도 새로운 지식을 열심히 전달하는 강의보다는, 유머중심으로 마음을 열어주는 재미있는 강의가 인기가 있고 긍정적 반응을 이끌어 낸다. 강의를 잘한다 못한다가 아니라, 강의가 재미있느냐 없느냐로 교수법이 평가되는 추세인 것을 보면 일터에서의 재미가 핵심요소인 것만은 틀림이 없다. "어른의 마음 속에는 놀고 싶어 안달하는 어린아이가 숨어있다"는 말처럼, 인간은 유희적동물인데, 많은 직장인들이 일 자체를 힘들어 한다. 일이란 목적달성의 방법이지 일 자체가 목적은 아닌데, 그 일을 즐겁고 재미있게 할 수 있다면 얼마나 좋을까? 일을 통해 인간의 본능적인 쾌락을 추구하는 일, 일에서의 즐거움을 찾는 능력이 바로 유머 리더쉽이란 전제하에 즐거운 일터 만들기 방법을 소개한다.

남자유아교사의 교사 성장 경험에 관한 자문화기술지

정병탁,하연희 한국생태유아교육학회 2023 생태유아교육연구 Vol.22 No.3

This autoethnographic study followed a male, early childhood teacher over 13 years. The study aims to explore what kind of teacher growth has occurred in the field of early childhood education experience from a perspective of a man. In addition, it aims to provide pertinent information to pre-service and current male early childhood teachers, increased social interest in support measures for them, and the accumulation of in-depth research knowledge. Therefore, data were collected separately on teacher experience from 2006 to 2021 (from a preparatory to becoming a male early childhood teacher with 13 years of experience). The classified materials comprise the following data: self-reminiscence, self-reflection, early childhood educational field, and autoethnographic colleague-teacher interview. The collected data were mutually connected and analyzed according to the comprehensive analysis procedure method. Therefore, the experience of growing up as a male early childhood teacher was as follows: becoming, surviving, and living as a teacher. Consequently, First, for me, the academic process and the sincerity of play facilitated professional growth and the discovery of strengths. Second, continuous introspection and experience of difficulties led to the growth of learning. Third, the process of meeting became a mentor for exemplary growth. Thus, the establishment of a new teacher image as a sincere teacher for the play was proposed. 본 연구는 약 13년간 유아교사로서 지내 온 한 남자의 자서전적 이야기이다. 남자유아교사로서 유아교육현장 속 구성원이 되어 어떠한 교사 성장이 이루어졌는지 탐구함으로써 남자예비유아교사 및 현직 남자유아교사들에게 관련 정보의 제공, 지원방안에 대한 사회적 관심 증대, 심화된 연구 지식의 축적을 목적으로 한다. 이를 위해 본 연구자의 남자예비유아교사 시절인 2006년부터 13년 차 유아교사가 된 2021년까지의 교사 경험에 관한 자료를 자기회상자료, 자기성찰자료, 유아교육현장자료, 자문화기술자 동료 교사 면담자료로 구분하여 수집하였다. 수집된 자료는 상호연관성을 가지고 있으며 포괄적 분석 방법 절차에 따라 분석하였다. 그 결과 남자유아교사로서의 교사 성장 경험은 교사 되어가기, 교사 살아내기, 교사 살아가기로 나타났으며 그 의의는 첫째, 나에게 학업 과정과 놀이 진심은 전문적 성장과 강점 발견을 촉진하였다. 둘째, 지속적인 성찰과 어려움의 경험은 배움의 성장으로 이어졌다. 셋째, 만남의 과정은 모범적 성장의 멘토가 되었다. 이와 함께 ‘놀이에 정성스러운 교사’라는 새로운 교사상의 정립이 제안되었다.

보육교사가 경험하는 아빠로서의 삶에 대한 자문화기술지: ‘100인의 아빠단’ 활동을 중심으로

정병탁(Jeong, Byung Tak),하연희(Ha, Yeon Hee) 한국육아지원학회 2021 육아지원연구 Vol.16 No.1

본 연구는 보육교사이자 아빠의 삶을 살아가는 연구자가 B광역시 100인의 아빠단 프로그램에 참여를 통한 육아경험과 아빠로서의 현실육아 경험을 성찰할 목적으로 실시된 자문화기술연구이다. 자료수집은 2020년 4월 중순부터 11월 말까지 약 7개월에 걸친 직접적인 참여관찰을 통해 경험일지, 미션사진자료, 아내와의 대화 회상자료 및 즉흥적 기억메모, 카페 댓글 등으로 이루어졌고, 분석은 이경숙(2015)의 귀납적 분석방법을 활용하였다. 연구 결과는 설레임과 부담감으로 시작되는 아빠의 삶, 즐거움과 공감으로 회복되는 아이·아내와의 관계, 반성과 성숙으로 이중정체성의 딜레마를 해소하는 성숙된 아빠의 삶이다. 이를 통해 처음 아빠로서의 삶을 인정하고 놀이의 주도권을 아이에게 주며 아내와 공감하며 고마움으로 관계를 회복하고 가정에서는 보육교사의 삶의 힘을 빼고 진정한 아빠의 삶에 취중하는 이중 정체성의 딜레마가 해소되는 긍정적인 경험을 함으로 성숙한 아빠의 삶으로 나아갈 수 있게 된 것에 의의가 있다. 이에 본 연구는 가정놀이의 현실적인 놀이지원방안과 아이중심 가정놀이프로그램과정 및 부모교육프로그램 제공이 필요함을 시사한다. This autoethnography study was performed by a male child care teacher and father, in order to contemplate the actual child rearing experience as a father through participating in the program titled ‘100 Fathers Committee’ consisting of fathers residing in B metropolitan city. The data including experience journal, mission pictures, reminiscences data on the conversations with a wife, impromptu memory memos, and comments listed in the online cafes were collected through direct participatory observation for about 7 months from mid-April to the end of November, 2020. The inductive analysis method (Lee, 2015) was used for data analysis. The findings were categorized into 3 domains: (1) a father’s life beginning with fluttering and burdening, (2) a relationship with a child and a wife recovering through happiness and empathy, and (3) a life of a mature father solving the dilemma of dual identity through reflection and ripeness. This study enabled the researcher to acknowledge life as a father, have a child take control of play, empathize with a wife, and recover the relationships with gratitude. Moreover, the researcher had a positive experience resolving the dilemma of dual identity by understating a role as a childcare teacher but concentrating on father’s role at home. This study implies the necessity of providing a child-centered home play program, a parent education program, and realistic play support for home plays

Encephalomyocarditis(EMC) virus was isolated from the mummified and stillborn pigs at a swine farm in Chonnam Province, experienced with EMC infection over the period Oct.~Dec. of 1989. In addition some cultural, serological properties of the isolates and experimental infections in the piglets were studied. The results obtained were as follows; 1. Two EMC virus strains with HA titers and CPE similar to EMC-ATCC were established in a baby hamster kidney (BHK)-21 cell line by inoculating homogenates of brain and heart of the 19 mummified or stillborn pigs and designated $K_3$ and $K_{11}$. 2. At the second BHK-21 cell line passage of the initial isolates CPE appeared after incubation for 16~18 hours, while at the fourth and fifth passage the highest titer of HA was recorded, titer of HA using rat and guinea pig erythrocytes. 3. One pig inoculated with the isolate $K_3$ showed dyspnea as clinical signs and died at the 10 days after inoculation at necropsy white necrotic foci were observed from the dead animal heart. 4. Although all the rest surviving pigs showed increases in antibody titer and body temperature of $40^{\circ}C$ above for the initial 2~4 days followed by the return to normal, there were no gross lesions when the animals were sacrificed at the 2 weeks after inoculation.

To evaluate pathogenicity in rabbits for Aujeszky's disease virus, NYJ-1 strain, isolated from pigs in Korea, the virus at 10^5.7 TCID_50/0.2㎖ was inoculated subcutaneously to rabbits, and virological and histopathological studies were carried out. All of the rabbits infected with 0.25㎖, 0.5㎖, l.0㎖ and 2.0㎖ of virus at 10^5.7TCID_50/0.2㎖ were died at 36 to 72 hours post-infection, manifesting the clinical signs of depression, frensy, scratching, biting and pruritus. The virus was recovered from the tissues of tonsil, spleen, brain, lung, liver, kidney and blood of the succumbed rabbits, showing the highest virus titers of 10^3.5 to 10^5.6TCID_50/0.2㎖ in tonsil and comparatively lower virus titers of 10^2.4 to 10^3.5TCID_50/0.2㎖ in brain. At autopsy no specific lesions were observed in parenchymal organs. By histopathological studies. congestion, hemorrhage and necrosis were recognized in the tissues of tonsil, liver, spleen, lung, kidney, adrenal gland and jejunum. Intranuclear inclusion body was observed in the epithelial cells of tonsil and jejunum.

The pathological and microbiological studies were carried out to investigate an acute, febrile, highly fetal, infectious disease of rabbits that had occurred in the Winter and in the Spring and that had begun to be reported in Korea from November, 1985. The clinical signs of this disease were characterized by high fever, lethargy, piercing shriek, convulsion, and sudden death with epistaxis, but often they were not observed. The predominant pathogical findings were severe congestion and hamorrhage in trachea, dark brown discoloration of liver by diffuse necrosis or acute viral hepatitis, and hamorrhagic damages of lung, heart, spleen, kidney, etc. The etiological agent was a small round virus, in 25-35nm in diameter and without envelope, thus looking like a picorna virus. This disease resembled what was called the 'Viral Hamorrhagic Pneumonia in Rabbits'(tentative name) that had been reported for the first time in China in 1984. It will be desirable that the disease should be renamed as the 'Viral Hemorrhagic Fever in Rabbits', the 'Acute Viral Hepatitis in Rabbits', etc. because of its charateristics and the basis of pathological findings. An inactivated vaccine is now in the process of preparation for the prophylaxis of this viral disease.
