학문적 사회화에 대한 교수들의 지각 연구

Susan Mathew,Diane Montgomery 한국주관성연구학회 2010 Journal of Human Subjectivity Vol.8 No.1

The purpose of this study was to empirically examine the perceptions of university faculty toward academic socialization. The sample for the study consisted of thirty-two faculty with varying ethnic backgrounds, both genders, and all faculty ranks represented six academic colleges from a comprehensive land-grant university. The 47 statements that comprised the Q set were sampled based on Tierney and Rhoad``s (1994) culture-based framework for socialization processes for faculty (culture of nation, profession, discipline, individual, and institutional). Interpretation of three factors from the data analyzed according to Q method were: (1) Best Fit; (2) Workhorse; and (3) Staying the Course. Best Fit believes that they are a good fit within the overall socialization scheme existing at the level of the discipline and university culture. Workhorses feel strongly that the profession demands a heavy workload imposing time constraints. As a result, they have little time to socialize personally and getting tenured is the focus. Staying the Course faculty members could be thought of as faculty who work hard at balancing their academic and personal roles. Implications for faculty development are discussed. 본 연구의 목적은 학문적 사회화에 대한 대학 교수들의 지각을 실증적으로 검토하는 것이다. 모두 6개의 주립대학으로부터 인종, 성, 그리고 직급이 다양한 32명의 교수들을 대상으로 연구가 진행되었다. Q 세트를 구성하고 있는 47개의 진술문은 대학 교수들의 사회화 과정을 문화적 틀로서 연구한 Tierrey and Rhoad(1994) 논문에 기초하여 선정되었다. 즉 자국문화, 분야, 원칙, 개인, 그리고 제도라는 기준이 사용되었다. Q 요인분석으로 세 개-(1) Best Fit (2) Workhorse (3) Staying the Course -요인으로 밝혀졌다. Best Fit은 기존의 일정 수준의 원칙과 대학문화의 틀 속에서 최적으로 사회화하고 있다고 믿으며, Workhorse는 교수직이 시간의 압박 속에서 과다한 일을 하고 있다고 강하게 믿는다. Staying the Course는 학문적 역할과 개인적 역할의 조화를 이루며 열심히 일하는 교수라고 할 수 있다. 교직개발을 위한 시사점이 논의되었다.

Background: Oral lichen planus (OLP) is an immune-mediated potentially malignant disorder of the oral cavity. Dysplastic OLP has an altered cytogenic profile and can progress into oral squamous cell carcinoma. The epidemiology of OLP is well-described in several relatively large series from various geographic locations, whereas such series from southern India is rare. The aim of the present study was to determine the epidemiology of OLP in a cohort of South Indian population. Methods: All the case data records of 29,606 patients who visited Mar Baselios Dental College and Hospital, Kerala, India from 2014 to 2015 were retrospectively reviewed. For data review, 122 patients of OLP were selected Estimated were type, number, and location of lesions, clinical manifestation, age of the patient, gender, onset and duration of lesion, stressful life style, habits, skin involvement and associated systemic illness, and presence/absence of dysplasia. Results: When the distribution of OLP among the gender was considered, we found more prevalence in females than males. Fifty-seven percent of patients were associated with stressful lifestyle. Reticular lichen planus was the most common clinical subtype found. Bilateral buccal mucosal was the common site, when the distribution of sites of OLP were compared (P < 0.05). Hypersensitivity reaction was frequently associated with systemic illness with OLP (P < 0.05). Anaplasia was found among 5% of lichen planus lesions. Conclusions: OLP patients had high incidence of hypersensitivity reactions and 5% of OLP lesions showed anaplasia. Long term follow-up is necessary to monitor the recurrence, prognosis, and malignant transformation of OLP.

Akashiwo sanguinea (Dinophyceae) extruding mucous from pores on the cell surface

This is the first recorded observation of Akashiwo sanguinea excreting mucilaginous substances from pores on the cell surface. Observations were from samples collected in the Caloosahatchee Estuary, Florida, USA during a bloom event, with densities of 672 cells mL-1 of A. sanguinea, including 51 cells surrounded by mucous. Scanning electron microscopy observations revealed that the mucous was secreted from thecal pores on the cell surface. The potential significance of mucous production is discussed.

Evaluation and Comparison of the Biopathology of Collagen and Inflammation in the Extracellular Matrix of Oral Epithelial Dysplasias and Inflammatory Fibrous Hyperplasia Using Picrosirius Red Stain and Polarising Microscopy: A Preliminary Study

Soma Susan Varghese,Sreenivasan Bargavan Sarojini1,Giju Baby George,Sankar Vinod,Philips Mathew,Anulekh Babu,Joseph Sebastian 대한암예방학회 2015 Journal of cancer prevention Vol.20 No.4

Background: The role of tumour inflammation and the dysplastic epithelial-stromal interactions on the nature of collagen fibres in the extracellular matrix of dysplastic epithelium is not fully understood. The present study was aimed to evaluate and compare the inflammation and pathological stromal collagen (loosely packed thin disorganized collagen) present in mild, moderate and severe epithelial dysplasias with that of inflammatory fibrous hyperplasias. The basement membrane intactness of epithelial dysplasias was also evaluated to determine if dysplastic epithelial mesenchymal interaction has any role in the integrity of stromal collagen in epithelial dysplasia. Methods: Oral epithelial dysplasias, inflammatory fibrous hyperplasia and normal oral mucosal samples were used for the study. Packing, thickness and orientation of collagen fibres in mild, moderate and severe grades of oral epithelial dysplasias (n = 24), inflammatory fibrous hyperplasia (n = 8) and normal oral mucosal samples (n = 8) were analysed based on the polarisation of collagen fibres in picrosirius red polarising stain under polarising microscope. Results: All the grades of epithelial dysplasias showed greenish yellow birefringence confirming the presence of loosely arranged pathological collagen in the presence of moderate inflammation. All the cases of inflammatory fibrous hyperplasia showed red polarisation hue and moderate inflammation. A statistically significant difference was found in the packing and orientation of collagen when epithelial dysplasias and inflammatory fibrous hyperplasia were compared (P < 0.01). When the intactness of basement membrane integrity was compared in all the groups of epithelial dysplasia, a statistically significant result was obtained (P < 0.05). Conclusions: Presence of significant amount of loosely packed thin disoriented collagen even in mild epithelial dysplasia suggests that tumourigenic factors are released to connective tissue stroma much earlier than expected. Hence we suggest considering the integrity of extracellular matrix collagen, intactness of basement membrane and inflammation associated with dysplasia along with the anaplasia of epithelial cells in the microscopic assessment of dysplastic epithelium.

Akashiwo sanguinea (Dinophyceae) extruding mucous from pores on the cell surface

This is the first recorded observation of Akashiwo sanguinea excreting mucilaginous substances from pores on the cell surface. Observations were from samples collected in the Caloosahatchee Estuary, Florida, USA during a bloom event, with densities of 672 cells $mL^{-1}$ of A. sanguinea, including 51 cells surrounded by mucous. Scanning electron microscopy observations revealed that the mucous was secreted from thecal pores on the cell surface. The potential significance of mucous production is discussed.

Anatomical variations of the hepatic artery in it’s extra hepatic journey: a cadaveric study with its clinical implications

Tintu Thottiyil Sukumaran,Susan Joseph,Swapna Ramakrishnan,Asha Joselet Mathew 대한해부학회 2022 Anatomy & Cell Biology Vol.55 No.3

Vascular anomalies are a serendipitous finding during surgeries and diagnostic angiography. Such variations are frequently encountered in the abdominal region. These anomalies are usually asymptomatic but the presence of hepatic arterial variations may lead to injuries of the liver during surgery. The present study was conducted on 35 adult embalmed cadavers, 31 males, 4 females from August 2015 to December 2021 in the Department of Anatomy, Amrita School of Medicine, Amrita Institute of Medical Sciences, Kochi. In this study of 35 cadavers, we present 3 variants: an accessory right hepatic artery, replaced common hepatic artery, replaced common hepatic artery anastomosis with accessory left hepatic artery and an arc of Buhler. One of our variants has not yielded a precedent in literature search. We have compared these variants with Michels and Hiatt classification. It is known that different variants arise at distinct stages of embryonic development. As specialists in anatomy, we have tried to correlate the variants in our study with their embryological origins.
