Background and Objective: Kikuchi's disease(KD) is an idiopathic, self-limited lymphadenopathy that was described as a distinctive type of necrotizing lymphadenitis affecting primarily cervical lymph nodes of young adults independently by Kikuchi and Fujimoto et al at first in 1972. The purpose of this study is a knowledge about clinicopathologic findings, many laboratory tests and differentiation of KD from other lymphadenitis due to lymphoma, systemic lupus erythematosus(SLE) and many viral disease. Materials and Methods: Thirty-four case of KD collected at Chonnam University Hospital in Kwang-Ju from 1992 through 2000 were evaluated with retrospective chart review. Results: The patients were consisted of 11 men and 23 women. All patients had tender or nontender cervical mass and fever was the most common associated symptom. The others was pain, weight loss, chills, cold sweating and headache et al. Multiple bilateral involvement of cervical lymphnodes was 25 cases(74%) and solitary involvement was 9 cases(26%). In laboratory tests, leukopenia was 12 cases(75%), elevated ESR 5 cases (34%) and elevated LDH 11 cases(69%). Conclusion: KD is necessary to differentiate from lymphoma and SLE, because of the different of therapeutic modality and prognosis. The diagnosis is established on the basis of histopathologic studies with excisional biopsy of lymph node.

As the population of the aged has increased considerably in Korea owing to elongated average life of the aged and the children's consciousness of supporting the aged has weakened, people are more concerned with their selfsupport in their old days. Then, they are more interested in the residential complex for the aged as a means of selfsupport. To acquire basic data for constructing residential and welfare facilities for the aged and to present thedirection of development, this research checks the influence that the degree of preparing for the aged, family relation and social relation have on the preference of residential and welfare facilities for the aged and intends to contribute to the construction of the residential and welfare facilities for the aged. Then, the result is as follows. First, as general opinion on the life of the aged, people are most concerned about the loss of social role when they become old, responding that the type of house is general house and they are unwilling to move in. Thus, it is found that residential complex for the aged cannot be positively carried on owing to such absolute lack of demand. Second, it is found that the aged prefers residential complex in the form of lease as it is less burdensome to them economically. Thus, government and self-governing body with public property and reliability should prepare positive policy and program to develop residential complex for the aged. Third, it is found that people in the following property further recognize the development of residential complex for the aged; higher income and schooling, family type in nuclear form. Female rather than male and those with high income rather than low income are more willing to move in later. Fourth, the preference of residential complex for the aged depending on the level of preparation for the old days is higher when preparation for retirement is positive and the motive for retirement is passive. The recognition of residential complex for the aged depending on the level of preparation for the old days is higher when preparation for the old days is positive and the preparation for retirement or health state is low. The intention to move in the facilities for the aged depending on the level of preparation for the old days is higher when preparation for the old days is positive, health is bad and preparation for retirement is voluntary. Fifth, the preference of developing residential complex for the aged depending on the organic relation is further recognized when the social linkage is not smooth. The intention to move in is higher when the sense of value among family is self-developing and modern. Thus, it signifies that the aged tend to bear responsibility rather than relying on the children.

본 연구에서는 도시관리계획 중 도시계획시설의 설치를 위한 평가체계II를 중심으로 토지적성평가 제도를 보다 효과적으로 수행할 수 있는 개선방안을 강구하기 위하여 사례연구를 수행하고 평가수행과정에서 나타나는 문제점의 합리적인 기술적 제도적 개선방안을 강구하였는데, 적성평가 결과인 종합적성값은 개발적성등급으로 평가되어 도시관리계획을 입안할 수 있는 것으로 분석되었다. 현재의 토지적성평가 수행방식은 지역여건을 반영할 수 있다는 원칙은 있지만, 이에 대한 구체적인 평가방법이나 명확한 기준의 부재와 원자료의 전산화 및 전문인력이 부족한 상황으로, 지역적 특수상황을 반영할 수 있는 평가요인이 적성등급의 판정에 상당한 영향을 줄 수 있는 요인임을 감안하여 지역간 개발격차나 지역여건의 차이를 평가지표에 반영할 수 있는 실행적 방안의 마련이 필요하다. Land suitability assessment has been enforced by the National Land Planning and Utilization Act since 2003 to prevent urban sprawl and protect natural environment. It assesses developmental, agricultural or preservable suitability of land parcel according to such criteria as soil, location and usability by local governments. Land suitability assessment system (LSAS) has been introduced to prevent cursory development by urban sprawl and to lead a harmonious development with conservation in the non-urban area. However, with the lack of experience and knowledge various problems have been arisen in the operation of this system, raising a question for the improvement of the assessment unit of land. The purpose of this study is to investigate methods of developing land assessment as a sustainable land use management tool. In this study, land suitability assessment has been executed through geographic information systems. On the basis oh the results of analysis, practical and institutional problems are described, and technical and institutional solutions are suggested.

본 연구에서는 표준화된 곰피추출물의 항산화 및 콜레스테롤 개선에 대한 효능평가를 통해 건강기능식품 소재로서의 가치를 검토하기 위해 총 폴리페놀, 총 플라보노이드 및 dieckol 함량을 측정하였으며 DPPH, ABTS radical 소거능, reducing power 및 FRAP 활성을 통하여 곰피추출물의 in vitro 항산화 활성을 조사하였고 표준화된 곰피추출물의 HMG-CoA reductase 저해 활성 및 세포 내 콜레스테롤 생성 억제 효능을 평가하였다. 표준화된 곰피추출물의 총 폴리페놀, 총 플라보노이드 및 dieckol 함량은 각각 9.64±0.04 mg GAE/g, 2.72±0.08 mg RE/g, 27.42±0.66 mg/g으로 나타났다. 표준화된 곰피추출물의 in vitro 항산화활성, HMG-CoA reductase 저해활성 및 세포 내 콜레스테롤 생성 억제 효능은 농도의존적으로 증가하는 경향을 보였으며 이는 표준화된 곰피추출물에 함유되어 있는 페놀성 화합물에 기인된 효능으로 사료되며 항산화성분, 항산화 효과, 콜레스테를 개선 효능간의 상관관계가 있음을 확인하였다. 향후, 표준화된 곰피추출물에 대한 in vivo 모델에서의 전임상 연구 및 작용기전 입증되면 인체적용시험을 통해 이중기능성을 갖는 건강기능식품의 개발이 가능할 것으로 사료된다. Ecklonia stolonifera, which belongs to the family Laminariaceae, is an edible perennial brown marine alga that is widely distributed, and is rich in polyphenols, including dieckol. Here, we investigated the radical scavenging activities of E. stolonifera extract (ESE) using various in vitro models. We further evaluated the effect of ESE on the cholesterol secretion inhibition activity in HepG2 cells, as well as the hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase activity. Our results showed that the total phenol, total flavonoid, and dieckol contents of ESE were 9.64±0.04 mg GAE/g, 2.72±0.08 mg RE/g and 27.42±0.66 mg/g, respectively. The antioxidant activity of ESE increased in a dose-dependent manner. In addition, the ESE inhibited cholesterol secretion from HepG2 cells with anti-HMG-CoA reductase activity. These results suggested that ESE possesses antioxidant and anti-cholesterol activities, and can therefore be used as a preclinical bioresource for development of health functional foods.

This study analyzes the present state of disaster management system in Korea and the international standardization trend of disaster management systems in advanced nations. ISO has developed international disaster management standards in ISO/TC 223 Societal Security Technical Committee, and the advanced nations such as U.S.A., U.K. and Japan are in competition with each others to reflect their national disaster management standards in international standardization. Each disaster management organization in Korea separately carries on the disaster management standardization and activities because national standards for the disaster management is not established yet. The national standardization efforts for disaster management system have to be executed in Korea to raise efficiency in disaster management activities and to cope with the international standardization of disaster management. 본 연구는 우리나라의 재난관리체계를 고찰하고 국제 재난관리표준화 동향, 선진국의 재난관리표준화 활동 및 국내 재난관리표준화의 현황을 분석하였다. 국제표준화기구(ISO)는 ISO/TC 223 Societal Security을 통하여 국제 재난관리규격을 개발하고 있으며, 미국, 영국 및 일본과 같은 선진국들은 자국의 재난관리표준을 국제 표준화 하기위해 경쟁하고 있다. 우리나라는 국가 재난관리표준이 제정되지 않아 재난관리 책임 기관별로 별도의 표준화를 추진하고 이에 따른 재난관리 활동을 수행하고 있다. 재난관리의 효율성을 높이고 국제적인 재난관리표준화에 적극 대응하기 위해서 우리나라에서도 국가재난관리표준의 제정과 재난관리시스템의 표준화가 구축되어야 한다.

최상길(Sang-gil Choi),황성우(Seong-woo Hwang),전호진(Ho-jin Jeon),김우혁(Woo-hyeok Kim),정도현(Do-hyeon Jeong),이다연(Da-yeon Lee),이상운(Sang-un Lee) 한국방송·미디어공학회 2021 한국방송공학회 학술발표대회 논문집 Vol.2021 No.11

방송장비가 네트워크 기술을 만나 진화하고 있다. 네트워크 케이블로 초고해상도 영상과 다채널 음향 데이터를 송·수신하고, 다수의 방송장비 제어를 가능케 하는 NDI(Network Device Interface)의 등장으로 방송장비와 네트워크 기술이 융합되고 있다. 최근 국내외 여러 기업이 네트워크 기반의 방송 솔루션을 출시하고 있어, 관련 산업계는 향후 방송장비 시장이 네트워크 기반으로 개편될 것으로 전망하고 있다. NDI는 뉴텍(NewTek)에서 개발한 IP 전송 프로토콜의 일종으로 무(無)손실, 압축, 제로(Zero) 딜레이, 멀티캐스트 등의 특징을 갖고 있다. 기존 비디오 전송 프로토콜이었던 SDI(Serial Device Interface)와는 다르게 네트워크에서 방송장비를 운용할 수 있도록 만들어진 프로토콜이다. 본 논문에서는 NDI를 기반으로 앞으로 다가올 포스트 코로나 시대에 대응할 효율적인 방송 환경을 제안하고자 한다.
