  • 현대에도 일부 소외된 지역에서는 의료 인력의 부족으로 인해 위·중증 환자에 대한 치료가 지연되는 경우가 많다. 의료 데이터에 대한 분석을 자동화하여 의료 서비스의 접근성 문제 및 의료 인력 부족을 해소하고자 하는 연구가 계속되고 있다. 컴퓨터 비전 기반의 진료 자동화는 훈련 목적에 대한 데이터 수집 및 라벨링 작업에서 많은 비용이 요구된다. 이러한 점은 희귀질환이나 시각적으로 뚜렷하게 정의하기 어려운 병리적 특징 및 기전을 구분하는 작업에서 두드러진다. 이상 탐지는 비지도 학습 전략을 채택함으로써 데이터 수집 비용을 크게 절감할 수 있는 방법으로 주목된다. 본 논문에서는 기존의 이상 탐지 기법들을 기반으로, 흉부 X-RAY 영상에 대해 이상 탐지를 수행하는 방법을 다음과 같이 제안한다. (1) 최적 해상도로 샘플링된 의료 영상의 색상 범위를 정규화한다. (2) 무병변 영상으로부터 패치 단위로 구분된 중간 수준 특징 집합을 추출하여 그 중 높은 표현력을 가진 일부 특징 벡터들을 선정한다. (3) 최근접 이웃 탐색 알고리즘을 기반으로 미리 선정된 무병변(정상) 특징 벡터들과의 차이를 측정한다. 본 논문에서는 PA 방식으로 촬영된 흉부 X-RAY 영상들에 대한 제안 시스템의 이상 탐지 성능을 세부 조건에 따라 상세히 측정하여 제시한다. PadChest 데이터세트로부터 추출한 서브세트에 대해 0.705 분류 AUROC를 보임으로써 의료 영상에 대한 이상 탐지 적용의 효과를 입증하였다. 제안 시스템은 의료 기관의 임상 진단 워크플로우를 개선하는 데에 유용하게 사용될 수 있으며, 의료 서비스 접근성이 낮은 지역에서의 조기 진단을 효율적으로 지원할 수 있다.

  • The prognosis of oral malignant melanoma is poor compared with cutaneous melanoma. It may be related to the difficulty of wide enough resection, the early hematogenous matastases, higher stage at initial diagnosis, and tendency to growth vertically. In the view of histological differences between oral mucosa and skin, it is impossible use Clark's and Breslow's classifications for prognosis. The great problem is that there is still no consensus on the treatment due to rarity. Because data collection from case reports is considered to be the best source of information and should be pooled to analyze key determinants of outcome, We analysed 6 cases of primary malignant melanoma of the oral cavity which were diagnosed and treated in Pusan National University Hospital on recent 7 years and reviewed the literatures. Immunohistochemical study on S 100 Protein, GP 100 (HMB-45) with biopsy was usable to confirm the melanoma. Three patients who were treated by surgery, chemotherapy are alive, but a patients who couldn't received benefit care surgically due to poor condition was died of distant metastasis, and two patients who refused to surgery are still alive. Neck dissection including wide excision is recommended if lymph node involvement is suspected. Additionally, adjuvant chemotherapy could be considered as supporting therapy for malignant melanoma.

  • This study tried to suggest the basic materials that can be efficiently applied in clinical cases by understanding problems through a content analysis of an adult nursing assessment tool and opinion agreement about nurse's practical usage presently used in the hospital. The study was carried out in 36 attached hospitals in nationwide universities from May to December, 1999, the two hundred and twenty five reports were for analysis. The contents of the collected nursing assessment tool were analyzed. It was found that the tool had been used with various names and content and there were instances of partial omission of a number of items, such as documentation and time records. Other results revealed that they mostly had a systematic classification of items, formation of details a form of a check list, and the effect of saving time. In spite of the adult nursing assessment tool, it was suggested that its style be subdivided according to the specialized of a department and that standardized style be amended and supplemented. The respondents also answered that there had to be education about continuous and sufficient health assessment skills on the physical examination record. The most frequently suggested items to be added were: past history, marital status, patient and caregiver's address and telephone number. It was found that a patient's education career, economic status, religion, hygienic practice, sexual life and hobby were the most frequently omitted items on record. The reason given wes because the items were associated with his/her privacy. These results highlight the importance of analyzing the content with an complete data collection, supplying basic content for a more accurate nursing record, computerization, sharing information and standardization of the form.

  • Cohorts are established and operated at medical schools as part of efforts to improve the quality of education. Chosun University College of Medicine clarified the purpose of establishing three cohorts in light of its core values and developed criteria and indicators for each purpose. An organization focusing on cohort construction and operation was established as the Cohort Committee under the Quality Improvement Committee, and guidelines were proposed. In addition, a database and system were developed to handle primary data efficiently, and tools for measuring psychological variables were created. The data collected by establishing a cohort, regions, and admission types of graduates were first analyzed for the following projects: (1) an analysis of the educational process and quality improvement to educate medical professionals who contribute to the community after graduation, and (2) an analysis of the educational process and quality improvement to secure excellence in the medical field (e.g., knowledge and clinical reasoning), using information on the academic achievements of students and graduates as primary data. Chosun University College of Medicine is conducting cohorts and longitudinal studies gradually, starting with a simple, practically feasible system to solve the difficulties faced in cohort establishment and operation. Medical educators hope that future data collection and analysis will improve the quality of medical school education and have practical implications.

  • Purpose: Following legal reform in 2013, the annual number of asylum seekers entering South Korea has increased from 1,143 in 2012 to 5,711 in 2015. We interviewed six African refugee mothers of young children regarding their health needs and barriers to access maternal child health services. Methods: We recruited mothers who had visited a clinic for immigrants between July 2013 and August 2015. Participants were African refugee women, aged over 18 years, who had given birth in Korea within the previous 5 years and had come to Korea over a year before recruitment. Interview questions examined participants' experiences in pregnancy and childbirth and concerns regarding their child's health status. Initial data analysis involved all researchers' immersion in the entire collection of transcripts. We then noted recurrent topics and themes and identified similar issues. Results: At the time of giving birth, 5 participants were asylum seekers and one had undocumented status. The following barriers impeded their access to maternal child healthcare: socioeconomic factors (unstable social identity, low economic status, difficulty obtaining health insurance), language barriers (lack of linguistically appropriate health information, limited access to translation services), and cultural barriers (religious and cultural differences). Weak social support also hindered access to healthcare soon after migration; however, social links with the community emerged as a key coping strategy following settlement. Conclusion: We identified barriers to maternal and child healthcare and coping strategies among African refugee mothers in Korea. Future research should assess refugees' health status and improve health access and literacy among refugee mothers.
