Due to the development of technology and medical care following the 4th industrial revolution, the medical paradigm is shifting towards patient-centered medical services. Based on the development of smart home technology, the residential environment is changing into a residential space that cares for and heals the lifestyles and the healthcare of families. As lifestyle changes, the concept of supporting smart home care based on the residential environment is making it possible to build a smart home IoT service design with enhanced accessibility and convenience for medical appointments and well-being lifestyle care. This paper is a study on user-centered health care smart home IoT service design suitable for family members based on the health care, beauty care, exercise care, and customized diet care beyond the conventional concept of health care monitoring. Based on the analysis, this paper proposes a personal care coordinate smart home service design in a human-centered wellness clinic care smart home service design environment. Human-centered wellness clinic smart home IoT service design is meaningful in presenting a vision for research on smart home service design that links hospital-linked and care-linked service industries, which should be considered from the smart home construction planning stage.

Rare earth barium copper oxide (REBCO) materials have shown the possibility of high-temperature superconductor (HTS) magnetic resonance imaging (MRI) magnets due to their elevated transition temperature. While numerous MRI magnet designs have emerged, there is a growing emphasis on estimating the cost before manufacturing. In this paper, we propose two designs of REBCO whole-body MRI magnets: (1) 1.5 T and (2) 3.0 T, the standard center field choices for hospital use, and compare their costs based on conductor usage. The basis topology of the design method is based on discretized solenoids to enhance field homogeneity. Magnetic stress calculation is done to further prove the mechanical feasibility of their construction. Multi-width winding technique and outer notch structure are used to improve critical current characteristic. We apply consistent constraints for current margins, sizes, and field homogeneities to ensure an equal cost comparison. A graph is plotted to show the cost increase with magnetic flux growth. Additionally, we compare our designs to two additional MRI magnet designs from other publications with respect to the cost and magnetic flux, and present the linear relationship between them.

대정공원은 운동장과 휴양 위락 시설을 겸비한 운동공원이다. 1910년 당시 부산 이사관 카메야마가 대만으로 이동할 때 그를 기념하기 위한 도시 시설로써 운동장의 건립에 관한 최초의 발의자는 당시 경제인들이었다. 하지만 운동장 건립은 카메야마의 죽음 이후인 1915년 무렵부터는 타이쇼 천황의 즉위 기념사업으로 진행하게 된다. 1917년 부산 부윤의 제안으로 운동장 건립이 본격화하고, 부지 선정 작업에 들어간다. 부지 선정지 후보를 두고 논의되는 과정을 살펴보면 운동장 부지 선정의 조건으로 먼저 운동장에 합당한 유효 부지 면적, 시가지와의 거리 다시 말해서 접근성, 그리고 예산이었다. 수차례의 논의와 실제 부지 조사의 결과, 전염병원이 이전하고 난 뒤 소학교가 들어오기로 한 부지를 공원 부지로 선정한다. 대정공원의 공사비는 모두 부산부민들의 기부금으로 마련하게 된다. 지역 상공인과 회사, 관공서, 지역별로 기부금 모금 위원회를 구성하여 조직적으로 모금하였다. 그 결과, 공사비 전액을 부민의 기부금으로 조성하게 된다. 대정공원은 크게 운동공간과 휴양, 위락 공간으로 구성되어 있었다. 공원의 세 방향에 입구를 두고, 외주는 식재를 하였다. 야구장은 공원의 중앙부에 자리 잡았고, 테니스 코트 2곳도 마련하였다. 일본 스모장도 공원의 북쪽에 마련하였다. 대정공원은 한국 근대 최초의 체육공원이었다. 그리고 공사비 전액을 주민의 모금으로 조성한 것이 특징이다. 1910년 당시 부산에서 운동장을 건립해야만 했던 이유를 밝히는 것이 남은 연구 과제다.

목 적: 움직이는 장기의 방사선치료시에 움직임을 고려한 선량분포의 연구가 많이 이루어지지 않았고, 정적인 상태로서의 선량분포가 고려된 치료 및 연구가 이루어졌다. 그래서 본 연구는 구동팬텀 시스템을 이용하여 움직이는 장기의 선량분포 계측을 시행하였다. 이 연구의 목적은 호흡에 따른 선량분포의 변화가 어떻게 일어나는지에 대한 실험적 계측에 대한 평가이다. 재료 및 방법: 호흡에 의한 움직이는 장기의 선량분포 측정을 위해서 다목적 팬텀과 구동팬텀을 고안 하였다. 다목적 팬텀의 구성은 아크릴과 코르크를 사용하였고, 아크릴의 밀도는 $1.14g/cm^3$이고 코르크는 $0.32g/cm^3$이다. 아크릴은 정상조직을 표현하기 위해 사용되었고, 코르크는 폐를 묘사하기 위해 제작 되었다. 측정용 필름은 가프크로믹 필름과 EDR2필름을 사용하였다. 구동팬텀 시스템은 상하좌우 2차원적인 움직임을 하도록 설계되었으나 본 실험은 1차원적인 움직임만으로 구동하여 측정하였다. 결 과: 코르크 팬텀에서 측정된 선량분포가 아크릴에서 측정된 선량분포보다 반음영이 크게 나타났다. 가프크로믹 필름으로 측정된 선량분포는 선량분포에 따른 광학농도가 낮기 때문에 분포곡선이 평탄하지 않았다. 내부장기의 움직임이 증가함에 따라 선량분포에서 반음영, 평탄도, 대칭도가 점점 증가하였다. 모든 가프크로믹 필름으로 측정된 선량분포는 EDR2필름으로 측정된 필름보다 평탄도나 대칭도가 좋지 않았지만 반음영은 비슷하게 분포되었다. 결 론: 가프크로믹 필름은 현상이 필요 없기 때문에 사용하기 편하고, 조그만 크기로도 쉽게 잘라서 사용할 수 있다. 또한 많은 양의 방사선을 조사할 수 있는 장점이 있다. 그러나 선량에 따른 광학농도의 변화가 작기 때문에 측정 시에 선량분포에 평탄도가 좋지 않다. 움직이는 장기의 방사선치료시 다목적 팬텀과 구동팬텀을 이용하여 질보정이 이루어진다면 치료효과를 향상시킬 것이라 사료된다.

목적 간 종양의 조영증강 컴퓨터단층촬영(이하 CT) 영상에 관한 인공지능 알고리즘의 성능과 안전성을 검증할 수 있는 표준 테스팅 데이터셋을 구축하고자 하였다. 대상과 방법 국내 4개 3차 의료기관의 복부 영상의학 전문가 4인이 모여 간 종양 진단 알고리즘의 성능과 안전성을 검증하기 위해 표준 데이터셋이 갖춰야 할 조건을 논의하였다. 각 기관마다 간세포암 75예, 전이암 75예, 그리고 양성 병변 30-50예씩 수집하여, 총 783명 환자의 CT 영상을 대상으로 하였다. 간세포암과 전이암의 경우 병리학적으로 확진된 경우만을 대상으로 하였다. 각 기관의 복부 영상의학 전문가들이 직접 환자의 임상정보를 추출하고 CT 영상에 관한 데이터 라벨링(labeling)을 수기로 시행하였다. CT 영상은 의료용 디지털 영상 및 통신(Digital Imaging and Communications in Medicine, DICOM) 파일로 저장하였다. 결과 복부 영상의학 전문가들이 수기 데이터 라벨링을 시행한 총 783 증례의 간 종양 조영증강 CT의 표준 데이터셋을 구축하였다. 알고리즘의 성능 및 안전성은 병변의 발견 여부 및 특성화의 정확도에 대해 민감도와 특이도를 계산하여 평가할 수 있다. 결론 본 연구에서 구축한 간 종양 조영증강 CT 영상의 표준 데이터셋은 임상의학 결정 지원시스템을 위한 기계학습 기반 인공지능 알고리즘을 평가하는 데에 활용될 수 있다.

최근 화재나 지진 등의 대규모 재난에 대한 위험이 증가함에 따라 효율적인 재난의료대응을 위한 자원관리체계가 요구된다. 이를 위해 행정안전부에서 재난관리자원 공동활용시스템 구축을 완료하였으나, 응급의료시설관련 자원은 에어텐트와 음압텐트가 장비로 분류되어 관리되는 등 투입시점, 존치기간, 운송 및 설치 방법과 같은 시설특성을 반영한 관리체계는 구축되어 있지 않고 있는 실정이다. 따라서 본 연구에서는 현재 재난관리 공동활용시스템에서 자재와 장비로 구분하여 관리하고 있는 재난관리자원의 효율적 관리를 위해 응급의료 시설자원을 고려한 응급의료 시설자원 관리 개선방안을 제시하고자 한다. 재난현장 응급의료 시설자원은 장비로 분류되는 의료자원과의 복합적인 연계를 통해 관리되어야 하므로, 현재 자재와 장비로 분류되어 관리되고 있는 재난관리자원 공동활용시스템에서의 반영이 요구되며, 재난관리자원 투입에 따른 금액을 고려한 시설구축방안에 대한 연구가 추진되어야 할 것으로 판단된다.

Objectives: The purpose of this study is to evaluate the input status of exposure-related information in the working environment monitoring database (WEMD) and special health examination database (SHED) for the construction of a national exposure surveillance system. Methods: The industrial and process code input status of WEMD and SHED for 21 carcinogens from 2014 to 2016 was compared. Data from workers who performed both work environment monitoring and special health examinations in 2019 and 2020 were extracted and the actual status of input of industrial and process codes was analyzed. We also investigated the cause of input errors through a focus group interview with 12 data input specialists. Results: As a result of analyzing WMED and SHED for 21 carcinogens, the five-digit industrial code matching rate was low at 53.5% and the process code matching rate was 19% or less. Among the data that simultaneously conducted work environment monitoring and special health examination in 2019 and 2020, the process code matching rate was very low at 18.1% and 5.2%, respectively. The main causes of exposure-related data input errors were the difference between the WEMD and SHED process code input systems from 2020, the number of standard process and job codes being too large, and the inefficiency of the standard code search system. Conclusions: In order to use WEMD and SHED as a national surveillance system, it is necessary to simplify the number of standard code input codes and improve the search system efficiency.

이 연구는 한양 도성의 동부(東部)에 조성되었던 왕실 원유(苑?) 함춘원(含春苑)을 대상으로 조영 사실과 운용적 특징의 규명에 목적을 두고 있다. 연구결과는 다음과 같이 요약될 수 있다. 성종(成宗) 연간에 창경궁이 건립된 이후 대비(大妃)들의 이어(移御)가 예정되면서 통망처(通望處)를 중심으로 논의된 차폐용 수목 식재가 동부 함춘원의 시원적 형태로 추정된다. 동부 함춘원은 창경궁 동측 궁장(宮墻)에 부속된 월근문(月覲門)부터 선인문(宣仁門)에 이르는 구간의 건너편 일대에 조영된 종방향의 원유(苑?)이었으며, 오늘날 서울대학교 병원 신축 본관의 서측 일대에 해당한다. 특히 조선시대에는 궁궐 내부에 조성된 원유만이 금원(禁苑)으로 불렸지만, 궁궐 외부에 조영되었던 동부 함춘원도 금원에 비견되는 상징적 위계적 공간으로 인식되었다. 동부 함춘원의 입지처(立地處)는 한양의 풍수지리 체계에서 내청룡(內靑龍)에 해당하는 요지(要地)였으며, 내청룡의 지맥(地脈) 보호를 위해 대규모의 토목공사는 허용되지 않았다. 인조(仁祖) 연간에 이르러 동부 함춘원의 일부는 마장(馬場)으로 분할되었다. 마장 일대는 마동산(馬東山), 방마원(放馬苑)으로도 불리었고, 휴식과 유락(遊樂)의 장소로 이용된 개방적 성격의 공간이었다. 동부 함춘원의 조성 초기에는 창경궁으로의 조망을 차폐하기 위해 속성수(速成樹)가 식재되었지만, 경모궁(景慕宮) 건립 이후에는 내청룡의 지기(地氣)를 보완하기 위해 대대적인 식목(植木) 공사가 이루어졌다. 특히 정조 연간에 유근문(?覲門)과 유첨문(?瞻門)이 건립된 이후 동부 함춘원은 궁궐(창경궁)-원유(함춘원)-사묘(경모궁)로 이어지는 전배(展拜) 동선의 거점으로 기능하였다.
