교육연극을 활용한 보건교사의 소진관리 프로그램 개발 적용 및 효과

강경민 한국교육연극학회 2023 교육연극학 Vol.15 No.3

본 연구는 교육연극을 활용한 소진관리 프로그램을 개발하고, 보건교사에게 적용하여 사회적지지 및 회복탄력성을 중심으로 직무소진이 어느 정도 해소되는지 여부를 확인하는데 있다. 본 연구의 연구 참여자는 의도적 표본추출(purposeful sampling)을 통해 선정되었으며, 보건교사로 구성된 단체에 소속된 교사 중 총 12명의 보건교사가 연구 참여자로 선정되었다. 프로그램 실행은 코로나19(COVID-19) 방역단계의 완화로 직접 대면하여 프로그램 진행되었으며, 2022년 10월 5일부터 10월 21일까지 주 2회 총 6일 간 진행되었다. 연구의 방법은 사례연구로서 정량적검사(직무소진, 사회적지지, 회복탄력성)를 통한 자료수집을 기본으로 하여 정성적 분석을 통해 보강한방식을 채택하였으며, 연구의 신뢰도와 타당성 보완을 위해 척도검사 및 회기별 사전-사후 검사, 개별인터뷰가 진행되었다. 본 연구는 제한적인 인원의 보건교사를 대상으로 직무소진 경감, 사회적지지, 회복탄력성 증진을 위한프로그램을 개발하였지만, 학교현장에서 코로나19 방역업무의 최일선에서 고생한 보건교사를 대상으로직무소진경감과 회복탄력성 증진에 유의한 결과를 도출하였다는데 그 의의가 있다. This research is to develop a burnout management program using drama education and apply it to health teachers to determine how much job burnout is resolved, focusing on social support and resilience. Participants in this study were selected through intentional sampling, and a total of 12 health teachers were selected as participants among teachers belonging to an organization composed of health teachers. The program was implemented face-to-face due to the relaxation of the COVID-19 quarantine stage, and was held twice a week from October 5 to October 21, 2022, for a total of six days. The method of the study was a case study, which was reinforced through qualitative analysis based on data collection through quantitative testing (job burnout, social support, resilience), and scale tests, pre-post tests for each session, and individual interviews were conducted to complement the reliability and validity of the study. This study developed a program to reduce job burnout, social support, and enhance resilience for a limited number of health teachers, but it is meaningful that it drew significant results for health teachers who suffered at the forefront of COVID-19 quarantine work at the school site to reduce job burnout and improve resilience.

ZrO₂ 첨가된 0.96(K_0.5Na_0.5)NbO₃-0.04SrZrO₃ 압전세라믹스의 환원분위기 소결

강경민,조정호,남중희,고태경,전명표,Kang, Kyung-Min,Cho, Jeong-Ho,Nam, Joong-Hee,Ko, Tae-Gyung,Chun, Myoung-Pyo 한국전기전자재료학회 2011 전기전자재료학회논문지 Vol.24 No.7

The most widely used piezoelectric ceramics are lead oxide based ferroelectrics (PZT). However, the toxicity of lead oxide and its high vapor pressure during processing have led to a demand for alternative lead-free piezoelectric materials. We synthesized Lead-free piezoelectric ceramics of $0.96(K_{0.5}Na_{0.5})NbO_3-0.04SrZrO_3+x$ mol% $ZrO_2$ [KNN-SZ+$xZrO_2$; x= 0~0.10] doped with 0.1 wt% $MnO_2$ by a conventional solid state method. We investigated the piezoelectric properties and microstructures of these disk samples sintered in reduced atmosphere in order to evaluate the possibility of the multilayered piezoelectric ceramics having the base metal such as Ni as a internal electrode. All of these KNN-SZ samples sintered in 3%$H_2-97%N_2$ atmosphere at $1,140^{\circ}C$ exhibit pure perovskite structure irrespective of the content of $ZrO_2$. Meanwhile, the sintering denisty and piezoelectric properties such as $K_p$, $Q_m$ and $d_{33}$ of KNN-SZ samples as a function of $ZrO_2$ content show the maxima ($k_p$=28.07%, $Q_m$= 101.34, $d_{33}$= 156 pC/N) at x= 0.04 and it is likely that there is some morphotropic phase boundary(MPB) in this KNN-SZ+$xZrO_2$ composition system. These results indicate that the ceramic composition is a promising candidate material for applications in lead free multilayer piezoelectric ceramics.

폐의 저악성 점액성 낭종은 보고된 예가 매우 드물며 기관지성 낭종 및 뮤신을 분비하는 기관지폐포암 형태의 선암과 감별이 필요하다. 63 세의 여자환자로서 흉부단순촬영 사진에서 우측 폐하엽에서 종괴가 관찰되었다. 술전 경피생검상에서 기관지폐포암으로 진단되었고 우측 폐하엽 절제술 및 임파절 제거술을 시행하였다. 절제된 폐내에서 다양한 크기의 다발성 낭성 종괴들이 보였고 종괴내에는 점액으로 채워져 있었다. 현미경상에서 낭종은 키가 큰 주상구조의 점액성 상피세포들로 구성되어 있었고 한정된 일부분에서 기관지폐포암양 병소가 관찰되었으나 기관지폐포암과 비교하여 세포의 비정형성(atypism)은 부족하였다. 수술후 환자는 합병증없이 퇴원하였고 12개월 추적관찰에서 재발이나 원격전이 소견은 보이지 않았다. 폐의 저악성 점액성 낭종은 술후 예후가 상당히 좋은 것으로 보고 되고 있으며 폐에서 발생하는 다른 신생물과는 감별이 필요할 것이다. Pulmonary mucinous cystic tumor of borderline malignancy is very rare and distinguished from bronchogenic cyst or adenocarcinoma of bronchoalveolar type. We present the case of a 63-year-old woman with a right lower lobe mass, found by chest radiographs. The preoperative diagnosis was made as bronchoalveolar cancer by percutaneous needle aspiration of mass. Right lower lobectomy and lymph node dissections were performed. The lobectomy specimen contained variable sized multilocular cystic mucous masses, filled with mucus. Microscopically, the cystic masses are lined with tall columnar mucinous epithelium but some area contains focal cellular atypism and bronchoalveolar cancer like foci. This foci are lack of cellular atypism consistent with bronchoalveolar cancer cell. After lobectomy the patient has remained free from recurrence and distant metastasis for following 12 months period. Pulmonary mucinous cystic tumor of borderline malignancy appears to have a favorable prognosis and should be distinguished from other lung neoplasms.

중,하부 식도및 분문에 발생한 식도 종양의 위장을 이용한 식도재건술의 외과적 치험

강경민,박재홍 대한흉부심장혈관외과학회 1996 Journal of Chest Surgery (J Chest Surg) Vol.29 No.6

The forty patients with carcirLoma of the esophagus or cardia seen at National Medical Center between November 1983 and April 1994 underwent surgical exploration. The esophagogastrectomy was carried out in 29 of 40 patients, one case through right thoracotomy, the others through left thoracotomy. Two patients underwent colon bypass surgeries due to upper esophageal cancer Transhiatal esop agectomy was performed In one case. Feeding gastrostomy or feeding jejunostomy were performed in 8 patients due to the advanced stage or malnutrition. In this report, we evaluated the long-term results in the 28 patients who underwent esophagogastrectomy for palliation through the left thoracotomy. There were 25 men(89%) and 3 women(11 %), and the mean age was 58.65$\pm$7.15 years(range, 46 to 73 years). The most frequent preoperative symptoms included dysphagia (22), weight loss (15), chest pain (6), vomiting (1), and hoarsness (1). Twenty-three patients had sqamous cell cancers of mid-and lower esophagus and five adenocarcionomas of cardia. One patient died in the hospital within 30 days of the op- eration for a hospital mortality rate of ).7%, Cause of death was sepsis due to anastomotic leakage. There were five additional complications in five patients; acute respiratory distress syndrome (1), post-op- erative bleeding (1), diaphragmatic hernia (1), acute renal failure (1) and late raft stenosis (1). The one year, 1틴o years, and three years acturial survival rate were 75.6$\pm$9.5%, 43.2$\pm$ 11.6%, 21.6: 10.5$\circledcirc$ re- spectively. The average survival was 21.8 months. The data from this study suggest that esophagogastrectomy through the left thoracotomy can achieve resonable long-term palliation for carci- noma of the esophagus. The operation can be performed with a low operative mortality and few serious postoperative complications.

A 71-year-old man presented with pain in the left eye that revealed a 3×3 mm deep corneal stromal infiltrate, with a 2×2 mm epithelial defect. The patient started topical moxifloxacin, voriconazole 2%, and natamycin for 2 weeks. However, the treatment was not effective and the corneal infiltration worsened. Subsequently, the patient underwent therapeutic penetrating keratoplasty. Thick brown/gray mold colonies on Potato Corn Meal Tween 80 agar was isolated from excised corneal tissue and on slide culture many septated, and club-shaped ascospores were revealed. Histological findings also showed numerous hyphae scattered in corneal tissue. A. alternata colonies were confirmed by 18S rRNA sequencing. Intracameral voriconazole was injected every other day for 2 weeks to eliminate remaining fungi on the deep corneal stroma. The remaining corneal infiltration was improved one month after the injection. During 5 months postoperative follow up, the infection did not recurred. In conclusion, deep corneal infection of A. alternata was effectively treated with intracameral voriconazole injection.

This study analyzes how grammars function in a discourse and contributes to the completion of the discourse beyond the way it used to be analyzed. For this purpose, it analyzes how discourses are constructed based on the development of the event, and analyzes how the adnominal clauses and adverbial clauses function in the construction, cohesion, and context of the discourses. The U.S. wiretapping case, which was used as data for analysis, began when it was revealed that South Korea was the target of wiretapping when confidential documents on the Ukraine war were circulated online. Within the news discourses, adnominal clauses and adverbial clauses locally respond to or link to the preceding sentence to increase the cohesion of the discourse and detail the discourse by providing details such as participants, times, and places. In addition, adnominal clauses form semantic confrontations to enhance the systematic relevance of the discourse and to integrate events that precede or cause in time so that the narrative can continue. Adverbial clauses are often used to resolve discontinuities at the new paragraphs.
