This Study constructs a dashboard system to synthetically and systematically monitor national R&D information based on data warehouse Managing the national R&D statistics and trend is important since it provides data for policies and decision making for national R&D Many agencies related to national R&D information collect the basic R&D statistic data which provides the basis of logical decision making and R&D policies The data has not well been used The data has not been consistently collected nor managed The raw data has not been organized nor processed to meet various demands The need has been arisen for a consistent national R&D monitoring system to increase the relevance, accessibility and efficiency of data for various users This study selects 25 key indicators based on the user requirements and designs data warehouse for supporting the indicators using star schema The dashboard system is developed in this study provides the infrastructure of monitoring national R&D information and analytic environment of supporting statistical analysis and time-series data analysis

학생수 변화와 학교 위치를 중심으로 본 구시가지역 초등학교 재배치 계획 모형 도출과 사례 적용에 관한 연구 - 부산시 D 구시가지역 사례 적용 -

최기석,Choi, Ki-Seok 한국교육녹색환경연구원 2021 교육·녹색환경연구 Vol.20 No.1

본 연구는 학생수가 급격히 감소하고 있는 구시가지역의 중장기 학생수 증감 추이, 통학구역 내 학교위치, 통학거리 등을 조사·분석하여 학교 재배치에 도움이 되는 실질적 방안을 제공하고자 하였다. 이를 위하여 선행연구 조사, 사례지역 분석 등을 실시하여 구시가 지역 학교 재배치 모형을 도출하였다. 구시가지역 학교 재배치 모형 도출은 먼저 대상지역과 학교별 학생수의 중장기적 변화추이를 분석하고, 학교별 학생들의 통학거리를 실측하여 통학구역 내의 학교 위치를 본 연구에서 제시한 지역 맞춤형 학교 배치 격자도 모형을 통해 학교를 배치한다. 그리고 학교 재배치 계획은 인근의 도시정비사업과 연계 등을 통해 학교용지를 확보하고 지역 소생활권 계획과 연계한 중장기적 학교 재배치 계획을 수립하여 시행할 필요가 있다. This study aimed to provide practical measures to help the relocation of schools by investigating and analyzing the trend of increasing number of students in the old city, the location of schools in the school district, and the distance to school. To this end, a model for the relocation of schools in the old city was derived by conducting prior research surveys and case area analysis. In order to derive the Planning Model of Elementary School Relocation in the Old city, the study first analyzes the mid- to long-term changes in the target area and the number of students by school, and places schools through a regionally customized school layout grid model presented in the study. In addition, the school relocation plan needs to be implemented by establishing a mid- to long-term school relocation plan in connection with the nearby urban readjustment project, etc.

This study places the focus on the programs of memorial architecture, which are scattered around all over the city. Presuming the city is a place where history is registered, the study attempts to explore the possible ways to transform the narrative property and sensuous experience of the space gained from such programs to build up urban identity. Focused on Holocaust memorial museums, in particular, which are built during the last decades of the 20th century, the study investigates how to transform such tragic history into the sense of place by the theme and message, form and spatial experience.

고려홍삼의 구강악취 억제기능

최기석(Ki-Seok Choi),이소정(So-Jung Lee),이정상(Jeong-Sang Lee),홍경숙(Kyung-Sook Hong),김정곤(Jeong-Gon Kim),김윤재(Yoon-Jae Kim),함기백(Ki-Baik Hahm) 고려인삼학회 2009 Journal of Ginseng Research Vol.33 No.4

구강악취 원인 물질인 H₂S를 발생시키는 NaHS로 RAW264.7 세포를 자극시킨 결과, VSCs 생성에 관련된 CSE 유전자 발현증가와 함께 IL-6, COX-2, iNOS와 같은 염증매개 cytokine이 증가하며, 아울러 본 대식세포나 백혈구 활성에 관련된 세포내 골격단백질인 ERM의 발현증가가 유도되었다. 이러한 사실은 이전의 연구결과인 VSCs의 생성이 위점막 염증 및 손상과 연관되어 있다는 이전의 연구를 증빙해주는 사실인데, 더욱 흥미로운 사실은 고려 홍삼의 전처치를 통하여 CSE의 억제는 물론 염증 연관 cytokine 및 ERM의 발현억제를 유도할 수 있으며, 이는 세포내 신호전달계인 p38 및 ERK의 억제, 주로는 ERK 비활성화를 통하여 작동됨을 규명하였다. 고려홍삼이 구강악취 환자에게서 증상 완화내지는 소멸을 위하여 매우 유용하다는 이전의 연구결과에 본 연구결과가 추가됨으로 고려홍삼에 의한 VSC 생성억제 기전이 관련된 유전자의 약화는 물론 cytokine 억제 및 백혈구 활성에 관련된 인자억제를 통한 항염증 작용에 근거한다는 기전을 추가할 수 있었다. Halitosis is a generally accepted marker of diseases in the oral cavity and of systemic and gastrointestinal disorders. Based on these authors’ previous findings (that (1) there is a close association between H. pylori infection and halitosis; (2) Korea red ginseng may suppress the colonization of H. pylori, fight H. pylori-induced cytotoxicity, and impose significant anti-inflammatory actions in patients with chronic gastritis; and (3) H. pylori infection is linked with the generation of significant levels of volatile sulfur compounds (VSCs), and the levels of VSCs correlate significantly with H. pylori-associated mucosal damages), in the current study, the authors documented the molecular mechanisms of Korea red ginseng’s efficacy in ameliorating halitosis. When the RAW 264.7 cells were treated with the H₂S releasing compound NaHS, the mRNA expression of cystathionine γ-lyase (CSE), IL-6, COX-2, and iNOS were more significantly induced compared with the vehicle-treated group. The cytoskeletal components of ezrin’s and moesin’s mRNA expressions were elevated by NaHS treatment accompanied by the activation of MAPK, p38, and ERK. Korea red ginseng pretreatment reduced both the NaHS-induced CSE expression and the proinflammatory genes (e.g., IL-6, COX-2, and iNOS) in a concentration-dependent manner. The ERM expression and the phosphorylation of p38 were also significantly reduced by Korea-red-ginseng pretreatment. Overall, Korea red ginseng pretreatment imposed significant anti-inflammatory effects through the downregulation of the NaHS-triggered proinflammatory gene expression, CSE, and ERM mRNA expression. Korea red ginseng could thus be said to be a key remedy of halitosis and to be effective in relieving gastric inflammation.

도시재생시대의 학교 이전,재배치 촉진 방안 탐색: 법제적 접근

최기석 ( Ki Seok Choi ),윤용기 ( Yong Gi Yoon ) 서울敎育大學校 初等敎育硏究所 2016 한국초등교육 Vol.27 No.1

저출산의 영향으로 학령인구는 지속적으로 감소되어 2030년에는 초등학교와 중학교 학령인구가 2007년의 각각 40% 수준으로 감소되고 고등학교 학령인구는 46%수준으로 감소되는 등 심각한 학생수 감소가 예상되고 있지만 개발사업은 지속적으로 추진되고 있어 신도시로의 학생이동과 구도심 학생수 감소에 따른 학생수 격차의 양극화는 지속될 것으로 전망되고 있다. 이에 대응하기 위해 정부에서는 2009년부터 학교 이전, 재배치 등을 포함하는 적정규모 학교 육성 정책을 추진하고 있으나 그 실적이 미미하고, 현재 「학교용지 확보 등에 관한 특례법」은 학교 신설의 특례만을 규정하고 있어 지역별 학생수의 급격한 감소 및 학생수격차 양극화 해소 등을 위한 학교 이전·재배치 사업에는 적용하기 어려운 것이 현실이다. 이에 본 논문에서는 학교 이전·재배치 사업의 체계적ㆍ효과적 추진을 위해 구도심 학교의 이전·재배치를 촉진할 수 있도록 하는 특별법안의 주요내용에 대하여 연구하였다. 특별법안의 주요내용은 첫째, 시·도교육감 및 시·도지사는 학교 이전·재배치가 필요한 경우를 사전에 계획하도록 학교 이전·재배치 종합계획을 수립하여 20년마다 수립하는 도시·군기본계획, 5년단위로 수립하는 도시·군관리계획에 반영하도록 하고, 둘째, 양호한 교육환경을 확보할 수 있도록 학교 입지에 대한 기준을 제시하고 개발사업자는 개발계획 수립 전에 학교입지에 대하여 협의하도록 하며, 셋째, 국가나 지방자치단체의 재정지원에 대한 특례를 규정하여 이전·재배치를 활성화시킬 필요가 있다는 것이다. 아울러, 향후 지속적으로 증가될 재개발이나 재건축과 같은 도시재생사업을 추진할 때 도시가 개발계획수립단계부터 교육 친화적으로 계획될 수 있도록 학교 친화형 도시재생 방안을 제안하였다. Under the influence of low birthrate, the number of students was continually on the wane, and in 2030, those of primary and middle school were reduced respectively to 40% in 2007, and the number of students in high school to the level of 46%, so the number of students is expected to decrease seriously, but developing projects is continuously under progress, and the bi-polarization of the number of students according to the transfer of students to new cities and the reduction of the number of students at the center of old cities is expected to continue. In order to correspond to this, the government is propelling the policy to grow schools of appropriate scales that include school relocation and merge since 2009, but the results are insignificant, and at present, 「ACT ON THE SPECIAL CASES CONCERNING THE PROCUREMENT, ETC. OF SCHOOL SITES」is stipulating only the exemptions of new school establishments, so it is true that it is difficult to be applied to school relocation project for dramatic reduction of the number of students at each community and resolution of bi-polarization of the gap between the number of students, etc. Therefore, this paper studied the major contents of special bill that enables to propel school relocation of the schools at the old city centers for systematic and effective propulsion of school reallocation project. The major contents of special bills are first, the urban & provincial educational superintendents and the mayor & governor shall establish the total plan for school relocation to plan the case in advance in which school relocation is required to reflect them on the urban, county basic plan established every 20 years, and urban, county management plan established every 5 years, and second, suggesting the criteria for school location so that good educational environment may be secured, and the developing operator shall discuss school location before establishing the development plan, and third, exemptions as to the financial support of the nation or local administration shall be stipulated to activate reallocation. Furthermore, when propelling urban regeneration project such as redevelopment or reconstruction to be continuously on the rise in the future, school friendly urban regeneration plan was suggested so that the city could be planned educationally friendly from the stage of establishing the plan of development.

Asymptotic Analysis on Service Differentiation with Customer Arrival Information

최기석(Ki-Seok Choi) 한국경영과학회 2008 韓國經營科學會誌 Vol.33 No.2

An interesting problem in capacitated supply chains is how to guarantee customer service levels with limited resources. One of the common approaches to solve the problem is differentiating service depending on customer classes. High-priority customers receive a better service at the cost of low-priority customers’ service level. One of common criteria to determine a customer’s priority in practice is whether he has made a reservation before arrival or not. Customers with a reservation usually receive service based on the time the reservation was made. We examine the effect this advance information of customer arrival has on customer service levels. We show the trade-offs between the leadtime and other system characteristics such as the proportion of high-priority customers, when the service level is high. We also suggest how to differentiate service using the asymptotic ratio of the service levels for both types of customers.
