Purpose FDG PET is effective in treatment response evaluationof cancer. However, there is no standard method for quantitativeevaluation of FDG PET, particularly regarding cytostaticdrugs. We compared various FDG PET quantitativemethods in terms of response determination. Methods A total of 39 refractory metastatic colorectal cancerpatients who received a multikinase inhibitor treatment wereincluded. Baseline and posttreatment FDG PET/CT scanswere performed before and two cycles after treatment. Standardized uptake value (SUV) and total lesion glycolysis(TLG) values using various margin thresholds (30–70 % ofmaximum SUV with increment 10 %, twice mean SUV ofblood pool, SUV 3.0, and SUV 4.0) were measured, withmeasurement target of the hottest lesion or a maximum of fivehottest lesions. Treatment response by the PERCIST criteriawas also determined. Predictive values of the PET indexeswere evaluated in terms of the treatment response determinedby the RECIST 1.1 criteria. Results The agreement rate was 38 % between response determinedby the PERCIST and the RECIST criteria (κ = 0.381). When patients were classified into disease control group (PR,SD) and non-control group (PD) by the RECIST criteria, percentchanges of TLG with various margin thresholds(particularly, 30–50%of maximum SUV) exhibited significantdifferences between the two groups, and high diagnostic powerfor the response by the RECIST criteria. TLG-based criteria,which used a margin threshold of 50 % of maximum SUV,exhibited a high agreement with the RECIST criteria comparedwith the PERCIST criteria (κ = 0.606). Conclusion In metastatic colorectal cancer, FDG PET/CTcould be effective for treatment response evaluation by usingTLG measured by margin thresholds of 30–50%of maximumSUV. Further studies are warranted regarding the optimal cutoffvalues for this method.

The dramatic spread of Coronavirus Disease 2019 (COVID-19) has profound impacts on every continent and life. Due to humanto- human transmission of COVID-19, nuclear medicine staffs also cannot escape the risk of infection from workplaces. Every staff in the nuclear medicine department must prepare for and respond to COVID-19 pandemic which tailored to the characteristics of our profession. This article provided the guidance prepared by the Korean Society of Nuclear Medicine (KSNM) in cooperation with the Korean Society of Infectious Disease (KSID) and Korean Society for Healthcare-Associated Infection Control and Prevention (KOSHIC) in managing the COVID-19 pandemic for the nuclear medicine department.We hope that this guidance will support every practice in nuclear medicine during this chaotic period.

The online agri-food market has grown rapidly, accounting for 16% of the total online market. It was surveyed that the proportion of households purchasing food online is increasing, and the frequency of purchase is increasing. In this situation, food safety and food labeling were investigated as important factors in online food purchase. Therefore, in this study, the effect of food safety and food labeling on online food purchase was analyzed for consumers who purchase food online. For the study, data from the 2020 Food Consumption Behavior Survey were used, and PLS-SEM analysis methods suitable for exploratory structural model research were used. As a result of the analysis, it was verified that food safety and food labeling are important factors for consumers who purchase food online. This study is expected to provide basic information on consumer purchasing behavior to online food market stakeholders such as online distributors and producers.

응답시간 향상을 위한 커넥션 스케줄링 기법

방지호(Jiho Bang),하란(Rhan Ha) 한국정보과학회 2006 정보과학회논문지 : 시스템 및 이론 Vol.33 No.1·2

웹서버가 클라이언트들의 요청을 처리하는 방법은 요청된 문서의 크기를 고려한 스케줄링 기법과 요청된 문서의 크기를 고려하지 않는 스케줄링 기법으로 구분할 수 있다. 웹 문서의 크기를 고려한 스케줄링 기법은 크기를 고려하지 않은 스케줄링 기법 보다 평균 응답시간이 우수하다. 크기기반의 스케줄링 기법인 SRPT(Shortest Remaining Processing Time first)는 웹 문서의 크기를 고려한 대표적인 스케줄링 기법으로 대부분의 연구들이 SRPT 스케줄링 기법을 기반으로 하고 있다. 그러나, 기존 연구들 대부분은 HTTP/1.0 기반으로 클라이언트들이 각각의 커넥션을 통해 HTML 문서에 포함된 다수의 문서들을 동시에 요청할 수 있는 HTTP/1.1 프로토콜의 특성을 고려하지 않았다. 본 논문은 HTTP/1.1 프로토콜을 기반에서 스케줄링 윈도우를 사용하여 커넥션의 전체 응답시간을 향상시키는 커넥션 스케줄링 기법을 제시하고, 성능분석을 통해 제안한 커넥션 스케줄링 기법의 커넥션 응답시간이 SRPT를 이용한 커넥션 스케줄링보다 10% 정도 향상됨을 보인다. The client request scheduling techniques for web server can classified into the scheduling techniques considering a document size to be requested and not. The scheduling techniques considering a document size to be requested provides a better average response time than another. As the size-based SRPT(Shortest Remaining Processing Time first) is typical, and the most of scheduling techniques considering a web document size are based on SRPT. Most of existing researches, however, have not considered the feature of HTTP/1.1 which enable the clients to request concurrent multiple inlined-contents in a HTML document via each connection. In this paper we propose a connection scheduling technique with the scheduling window which provides a better response time in HTTP/1.1. The experimental results show that the performance with the proposed approach is improved about 10% more than the connection scheduling with SRPT.

역사교육에서 ‘역사의식’연구의 추이와 전망

방지원 한국역사교육학회 2012 역사교육연구 Vol.- No.16

Until now, in the circle of history education in Korea, studies on historical consciousness have been done in two main different contexts; in the view of developmental stages of students in learning ability of history and the ultimate objective of history education. The greater part of studies, have been rest on developmental stages of students based on ‘piaget-Japanese model’. But the products of those studies for securing the empirical basis of 'sequence' in history education, has been too poor requital for their efforts. Meanwhile, There are serious lack of criticism and vigour in debate about historical consciousness as ultimate objective of history education. In this approach, historical consciousness has been defined as a kind of conscious of one's existence characterized of critical thinking, reform-oriented attitude and so on. The underlying problem of little progress in this subject is that historical consciousness has been discussed from the perspective of 'value neutrality', representing nation-centric tendency of history teaching in korea after liberation in 1945. Recently, historical consciousness began to receive attention from academia with its educational, and social value. Judging from what is going on in our academia, we presuppose that democracy, peace, antiwar, environmental protection will be linked actively by historical consciousness as objective of history education. This is very inspiring sign for history education. In 2010~2011, Institute of History Education made a large research plan of study about student and teacher's historical consciousness. Then, combination with Association of History Teacher, the Institute practiced investigation on a national scale. It focused on the formation process of historical consciousness and interactions between students and social-educational environments operating in the process. The result of research, huge information about student's understanding of history and history education was gained. And the project hold very strongly that history education must contribute to the growth of democracy. So, the investigation has the potential to be differentiated from advanced researches according to the degree of supplementation in a follow-up study. 지금까지 역사교육계에서는 ‘역사의식’ 개념을 크게 두 가지 맥락에서 사용해왔다. 그 중 하나인 ‘역사의식발달단계’에 입각한 연구들은 ‘학습자의 관심 수준과 정서적 특징, 지적 사회적 발달 정도에 맞는 역사학습’을 과제로 삼았다. 동시에 역사의식은 역사교육의 목적 또는 목표 차원에서도 오랫동안 논의되어 왔다. 이 때 역사의식의 내용은 역사적 존재의식과 비판적 문제의식이었다. 그런가하면 양자를 종합하여 역사의식을 역사적 존재의식으로 보고, 역사의식 함양에는 ‘역사의식발달’이라 부르는 사고의 성장 과정이 필요하다는 방식으로 종합하기도 했다. 그런데, ‘역사의식발달단계’에 따른 경험적 조사 연구를 제외하면 우리 역사교육계의 역사의식 연구는 그리 활발하지 못하였다. 역사교육 연구에서 ‘목적론’ 논의 자체가 매우 부족했다는 점, 학생 개인의 삶, 사회 발전의 전망 형성에 역사교육이 어떻게 기여할 수 있을 것인지에 관한 토론이 부족했던 점, 역사교육의 이론적 연구가 은연중에 가치중립적인 연구 경향을 띠어 왔던 상황 등이 이유로 작용했을 것이다. 최근 학교 현장과 학계에서 일고 있는 역사의식에 대한 새로운 관심, 변화의 흐름들은 ‘오늘날’의 역사교육이 개인의 삶과 사회적 전망 및 그와 관련된 가치에 적극적으로 관심을 가질 것을 요청하며, 민주주의나 평화, 반전, 환경, 인권, 민족, 상호 공존 등 미래적인 가치를 바탕으로 학생들의 과거, 현재, 미래 인식을 다룰 것을 제안한다. 이는 ‘역사의식이란 무엇인가’에서 ‘어떤 역사의식인가’로 질문의 방향을 전환해야 한다는 의미이기도 하다. 2010년 전국역사교사모임과 역사교육연구소에서 실시한 대규모의 역사의식조사는 기존의 ‘역사의식조사’ 연구와는 차별화된 문제의식에서 출발했다. 주체의 관점에서 역사의식을 재개념화 하였으며, 역사의식 자체의 역사성에 주목하여 역사의식의 형성 과정 및 요인, 과거-현재-미래 인식을 종합한 접근, 학생 인식의 차이점을 기초한 학교급별 역사교육의 구성 등을 조사 연구의 목적으로 삼았다. 이로써 향후 역사교육 목적으로서 역사의식 문제에 접근할 때 생각해 보아야 할 여러 논점들을 제기하였다.
