유영선,조명준,정혜영 최신의학사 1977 最新醫學 Vol.20 No.1

Aspergillosis is one of the first visceral mycoses to be recognized in man. Pulmonary infection of this genus of Aspergillus is fumigatus, most commonly presenting as secondary invasion of pre-existing cavitary lesion. During the period of January, 1962 to October, 1976, the authors have experienced 10 cases of pulmonary aspergillosis in Chest Surgery Department, N. M. C. , all the cases had been treated with anti-tuberculous drugs for the periods ranging from 2 to 20 years under the diagnosis of pulmonary tuberculosis. Six of ten were male and four were female. The most common presenting symptoms were intermittent hemoptysis, blood tinged sputum, increased expectoration and cough for a long time. Eight of ten were performed pulmonary resectional surgery, 3 pneumonectomies, 5 lobectomies. All of the cases operated were confirmed by histopathological examination to be aspergillosis superimposed on underlying tuberculosis, bronchiectasis. One patient died following surgery because of acute hepato-renal insufficiency during postopertive Amphotericin B therapy. Remaining all the cases has been doing well in this follow-up period ranging from 6 months to 14 years.

The purpose of this study was to investigate effects of osteoporosis on extraction wound healing in the calcium deficient rat. In order to carry out this study, ten-week old Wistar strain rats weighing about 300 gms were selected. When the rats reached thirteen-week old, rats' mandibular first molars were removed. The rats were then divided into three groups: Group l(rats given a normal diet both before and after tooth extraction), Group 2(rats given a low calcium diet for three weeks before tooth extraction and a normal diet after tooth extraction), and Group 3(rats given a low calcium diet for three weeks before and after tooth extraction). The healing of extraction wounds, as assessed by microradiography, autoradiography, and histopathologic examination, were compared among these three groups. The obtained results were as follows : I. In Group 1, newly formed bone and active uptake of 45Ca around extraction wound were noted on the 3rd and the 7th day. On the 14th and the 21st day, the extraction wounds of this group showed the bone trabecular formation and active 4Ca uptake in the extraction wound and alveolar crest. The more prominent bone trabeculae with a less uptake of /sup 45/Ca were noted on the 42nd day. 2. In Group 2, newly formed bone and thinning of alveolar bone trabeculae with more extensive uptake of /sup 45/Ca than that in Group 1 were noted on the 3rd and the 7th day. On the 14th day, bone trabeculae were less thicker than that in Group 1. The prominent bone trabeculae in the extraction wounds and alveolar crest were noted on the 21st and the 42nd days. 3. In Group 3, newly formed bone was noted on the 3rd and the 7th day. Alveolar bone trabeculae and uptake of /sup 45/Ca were similar to that in Group 2. On the 14th and 21st day, bone trabeculae were less thicker than that in Group 2 and Group 3. The osteoporotic change with active uptake of /sup 45/Ca was markedly noted on the 42nd day.

As the ‘Untact Service’ has become a trend due to the outbreak of COVID-19, the demands of non-face-to-face customer channels are dramatically increasing. In particular, many people are now interesting in the non-face-to-face customer channels with Information Technology (IT) and Artificial Intelligence (AI) such as app, social network service, portal, chatbot, etc. However, little is known about such new channels’ quality factors. Thus this study created non-common and common quality factors of new five channels – app, social network service, portal, chatbot, and homepage – and compared them with the traditional call center channel. We then analyzed the relative priority of each six non-face-to-face channels depending on whether response time is real-time or non-real-time, and investigated the relative priority depending on how much customers involved in the non-face-to-face channels. With AHP analysis, we found that solving customers’ problem has the highest priority among all factors. In addition, new channels with the Internet has higher priority in information security and personal information breach. In addition, we found that the response time to customers has higher priority in non-real-time channels, and found that the information integration across channels is an important inssue for highly involved customers. Based on these findings, this study provides a guideline for management teams of non-face-to-face counseling channels in the era of the Untact Service. 정보 통신, AI 기술의 발전과 코로나 바이러스로 인해 언텍트 서비스가 트렌드가 되면서 비대면 상담채널의 수요와 필요성 역시 증가하고 있다. 그러나 상담채널 품질 평가 요인에 관한 연구는 미흡한 실정이다. 따라서, 본 연구에서는 총 37개의 품질 평가 요인들을 도출하여 AHP 분석을 통해 6개 비대면 상담 채널별 전체, 응답 형태, 응답자 속성에 따라 상대적 중요도(우선순위)를 분석하였다. 분석결과 문의내용 해결의 상대적 우선순위가 가장 높게 나왔으며 이를 통해 비대면 상담채널 본질의 중요성을 확인하였다. 또한, 사칭계정 관리와 정보 품질 확보의 중요성을 재확인하였다. 반면에 UI 디자인 등의 디자인 품질의 상대적 우선순위가 낮은 것을 확인했다. 또한, 응답 형태가 비실시간인 상담채널들에서 응대 신속성 항목에 높은 우선순위를 가졌으며 이용 수준이 높을수록 통합적인 상담채널 운영을 중요하게 고려하는 것으로 나타났다. 해당 결과는 언텍트 서비스 시대에 비대면 상담 채널들 운영을 위한 가이드라인을 제시함으로써 실무적 시사점을 제공할 것으로 기대된다.

To address recent environmental pollution, bio plastics such as biodegradable, oxo-biodegradable, and bio-basedplastics have attracted much attention in a variety of industrial fields. The critical disadvantages of the weak mechanical strengthand expensive product cost were gradually solved by extensive researches. As an alternative for petroleum-based plastics, the bioplastics have been applied to various items. To popularize the bio plastics, certification marks and technical standardization havebeen developed in the world. This article provide an over view on the recent trend on the commercialization and nationalcertification marks. 최근 환경문제를 해결하기 위하여, 생분해, 산화생분해, 바이오베이스 등 바이오 플라스틱에 대한 산업적인 관심이 증가되고있다. 기존의 중요한 문제로 지적된 낮은 기계적물성과 비싼 제조 비용 문제는 해결되고 있다. 석유 유래 플라스틱의 대안으로서 바이오플라스틱은 다양한 제품으로 개발되어 적용되고 있다. 바이오플라스틱의 활발한 보급을 위해서, 각국은 인증 마크와 표준 제도를 운영하고 있다. 본 총설에서는 최근의 상업적 및 국제 인증 마크에 대한 최근의 동향을 살펴보고자 한다.

Recent Advances in the Development of Experimental Animal Models Mimicking Human Aortic Aneurysms

유영선,박형섭,최금희,이태승 대한혈관외과학회 2015 Vascular Specialist International Vol.31 No.1

Aortic aneurysm is a common and life-threatening disease that can cause death from rupture. Current therapeutic options are limited to surgical or endovascular procedures because no pharmacological approaches have been proven to decrease the chance of expansion or rupture. The best approach to the management of aortic aneurysm would be the understanding and prevention of the processes involved in disease occurrence, progression, and rupture. There is a need for animal models that can reproduce the pathophysiological features of human aortic aneurysm, and several such models have been studied. This review will emphasize recent advances in animal models used in the determination of mechanisms and treatments of aortic aneurysms
