유아교사가 되려는 남자 대학생에 대한 연구

조경자,이현숙 한국유아교육학회 2004 유아교육연구 Vol.24 No.1

본 연구는 유아교육과 남학생들의 전공 선택 동기와 교사 교육과정에서의 경험, 유아교사직에 대한 인식 및 전망과 기대를 파악하기 위한 것이다. 전국 14개 대학의 남학생 21명을 면접한 결과, 전공 선택의 주요 동기는 어린이에 대한 관심과 사랑, 그리고 자신의 성이 유아교육 분야에서의 성취에 유리할 것이라는 기대 등이었다. 남학생들은 학교생활 초기에 어려움을 겪으나, 본인의 적응 노력과 동료 여학생과 교수로부터 긍정적 배려와 기대를 받으며 적응해 간다. 점차 유아교육에 대한 이해와 교사직 수행에 대한 의욕과 더불어 취업, 저임금, 남교사가 받아들여질지 여부에 대한 염려도 증가하였다. 이들은 자신을 통해 남자 교사에 대한 인식이 향상되고 유아교사직을 원하는 남학생들이 늘어날 것을 기대하고 있었다. This study asked male students enrolled in an early childhood course of study why they had chosen that major, what their experiences had been during their study, and how they themselves perceived male early childhood education teachers. Twenty-one male students of 14 universities and junior colleges from all over the country were interviewed. The male students articulated their motivation to enter the field of early childhood teaching as love and concern for young children. They also expected that, as males, they would have more advantages in their careers and more social success than female teachers. In the beginning of their studies, they found it difficult to be in the minority but they get close attention from their professors and the female students in the class. As they gained a strong understanding of early childhood education, they desired to be good teachers of young children. But, at the same time, they expressed that they are gradually becoming more and more anxious about their chances for employment, the low salaries associated with the field, and the biased views against male teachers in early childhood education. So they were hoping to be engaged as teachers for a certain period of time or to get another job outside of their major field of study. They all looked for improvement in the general perception of male-teachers in the field of early childhood education and hoped that there would be an increase in the number of male students majoring in early childhood education.

Basaloid Squamous Cell Carcinoma of the Upper Aerodigestive Tract

조경자 대한병리학회 2010 Journal of Pathology and Translational Medicine Vol.44 No.1

Basaloid squamous cell carcinoma (BSCC) is an uncommon variant of squamous cell carcinoma (SCC), usually occurring in the larynx, hypopharynx, oropharynx and esophagus. BSCCs have been reported from various geographic areas, but esophageal BSCCs are more prevalent in Asia. The morphology of BSCC is quite characteristic, but BSCC occasionally needs to be differentiated from neuroendocrine carcinoma or adenoid cystic carcinoma. Human papillomavirus16-associated oropharyngeal SCC with poorly differentiated or basaloid features has recently been recognized as a new clinical entity with a different etiology and prognosis. Nonoropharyngeal BSCC appears to share etiologic factors, genetic alterations and an immunoprofile with conventional SCC of the upper aerodigestive tract. However, the divergent differentiation of BSCC into various non-basaloid, epithelial or mesenchymal elements suggests the participation of more mulipotential cells than in SCC. The biologic behavior of BSCC has been reported to be worse than or equal to that of SCC, yet the data including the increasing numbers of human papillomavirus-associated cases now require reanalysis. It is presently uncertain whether BSCC is a histogenetically or clinically unique disease entity.

부산지역 초등학생의 비만도에 따른 식습관 조사

조경자 한국식생활문화학회 2004 韓國食生活文化學會誌 Vol.19 No.1

The factors of obesity related with food habits were assessed to provide information for nutrition education database. The subjects in this study were 234 primary school children in Busan. Children were classified into normal and obese groups(mildly obese, moderately obese and severely obese) by obesity index. In self-recognition of body image, only 28.6% of MI group considered themselves as overweight or obese. 87.2% of the subjects controlled their weight method with exercise. With regard to meal speed, 64.5% of the subjects ate fast(≤15 min). The study also found that 79.8% of the subjects ate breakfast, 56.4% of the subjects them were moderate by obese, 40.8% of the subjects ate snacks after dinner. Eating speed, meal volume and snacks money per day were significantly different in obesity. Preference for eating out was Korean Chinese, Western and Japanese food, in order. Favorite food for snack, such as ddukbokki, fruits, milk, fried foods and candy and caramel were significantly different in obesity(p<0.05). However hamberger, pizza and chocolate were not significantly different in obesity. The most preference snack for all the subjects were fruits and ice cream. In food preference, potato, dduk, meats, fishes, cheese, milk, ice cream were significantly different in obesity. The distasteful food for subjects were patbab, vegetables, shellfishes and salt-fermented foods. From above results, obesity of children was related to meal speed, meal volume and snacks money per day. Therefore, these results suggest that continuous and practical nutrition education to change food habits are necessary to avoid child obesity.

Basaloid Squamous Cell Carcinoma of the Head and Neck: Subclassification into Basal, Ductal, and Mixed Subtypes Based on Comparison of Clinico-pathologic Features and Expression of p53, Cyclin D1, Epidermal Growth Factor Receptor, p16, and Human Papillom

조경자,정세운,김성배,이상욱,최승호,남순열,김상윤 대한병리학회 2017 Journal of Pathology and Translational Medicine Vol.51 No.4

Background: Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma with distinct pathologic characteristics. The histogenesis of BSCC is not fully understood, and the cancer has been suggested to originate from a totipotent primitive cell in the basal cell layer of the surface epithelium or in the proximal duct of secretory glands. Methods: Twenty-six cases of head and neck BSCC from Asan Medical Center, Seoul, Korea, reported during a 14-year-period were subclassified into basal, ductal, and mixed subtypes according to the expression of basal (cytokeratin [CK] 5/6, p63) or ductal markers (CK7, CK8/18). The cases were also subject to immunohistochemical study for CK19, p53, cyclin D1, epidermal growth factor receptor (EGFR), and p16 and to in situ hybridization for human papillomavirus (HPV), and the results were clinico-pathologically compared. Results: Mixed subtype (12 cases) was the most common, and these cases showed hypopharyngeal predilection, older age, and higher expression of CK19, p53, and EGFR than other subtypes. The basal subtype (nine cases) showed frequent comedo-necrosis and high expression of cyclin D1. The ductal subtype (five cases) showed the lowest expression of p53, cyclin D1, and EGFR. A small number of p16- and/or HPV-positive cases were not restricted to one subtype. BSCC was the cause of death in 19 patients, and the average follow-up period for all patients was 79.5 months. Overall survival among the three subtypes was not significantly different. Conclusions: The results of this study suggest a heterogeneous pathogenesis of head and neck BSCC. Each subtype showed variable histology and immunoprofiles, although the clinical implication of heterogeneity was not determined in this study.

사람 Low Density Lipoprotein (LDL)에 대한 Rooibos tea의 항산화 활성

조경자,김희숙,박종옥,류병호 경성대학교 2001 論文集 Vol.22 No.1

This study was investigated to antioxidative activity of crude catechin extracted from Rooibos tea against low density lipoprotein(LDL) oxidation. The crude catechin inhibited the copper-mediated oxidation of human LDL at the concentrations of 50 and 100 ㎍/㎖ in the presence of 5 μM CuSO4. The crude catechin also inhibited LDL oxidation induced by macrophage J774 cell. LDL oxidized by copper mediated and cell induced oxidation was degraded by macrophage at a much greater rate than native LDL. The electrophoretic mobility of oxidized LDL by addition of crude catechin was faster than that of native LDL. The results provided a possibility that crude catechin of Rooibos tea might protect LDL against oxidation in atheroscleotic lessions.
