Objectives: Ryodoraku is a physiological function test using electric current. Since it can evaluate the patient's overall condition as well as a function of individual organs, Ryodoraku can be assumed as an effective way to diagnose chronic obstructive pulmonary disease (COPD). Therefore, this study aimed to investigate the values of Ryodoraku for diagnosing COPD. Methods: We designated a COPD group, who were over 40 and satisfying COPD criteria, $FEV_1$/FVC<0.7. The Control group also consisted of members over 40 years old but without COPD and any other lung disease. We conducted a comparative study by checking the Ryodoraku score (RS), the average of Rt.&Lt. H1 (mean H1), the mean difference value between both H1s (${\mid}H1^R-H1^L{\mid}$) and the ratio of patients whose RS was under 40. Then we investigated the correlation between the mean H1 and the results of pulmonary function test (PFT). Results & Conclusions: In the COPD group, RS, mean H1 and ${\mid}H1^R-H1^L{\mid}$ were significantly lower and the ratio of 'RS<40' patients was meaningfully higher than in the Control group. On the other hand, PFT seems not to be replaced by Ryodoraku since there was no correlation between mean H1 and the results of PFT. Though more experiments and researches are needed to be further confirmed, Ryodoraku is expected to be an adequate way for prediagnosing and following up the COPD patients.

목구조 건축물의 거동성능 향상을 위한 강재이력댐퍼 개발
장석현,양원직 대한건축학회 2022 대한건축학회논문집 Vol.38 No.9
Recent earthquakes in South Korea have resulted in various seismic reinforcements being developed with a focus on a building’s seismic performance. Among vibration devices, Korea has been actively studying Steel Hysteretic Dampers due to its characteristics of having exceptional plastic deformation capacity and advantages in horizontal resistance in the instance of earthquakes. However, the disadvantages of Steel Hysteretic Dampers involve its difficulties during the application to three-dimensional shapes and its inability to serve as a reinforcement to buildings once the strut has been destroyed. This study proposes a damper model with twice the displacement along with the ability to secondary behavior after the strut has been destroyed and can be applied in its flat form. For this experiment, wooden structures were selected to apply reinforcement construction methods in situations where large deformations could occur. The results revealed there was a synergistic effect with the increase in strength for all specimens, and the possibility of preventing overturning through secondary behavior. 최근 국내에서 발생한 지진으로 내진성능 확보에 대한 관심이 집중되고 있으며, 여러 내진보강이 발전되어 왔다. 특히 제진장치를 이용한 보강 방안 중, 강재이력댐퍼는 뛰어난 소성변형능력을 바탕으로 지진과 같은 수평 방향 저항에 유리하여 최근 국내에서 활발히 연구되어왔다. 그러나 강재이력댐퍼는 입체적인 형상을 대상으로 적용이 어렵고 스트럿 파괴 후 보강 역할을 할 수 없다. 이 연구에서는 스트럿 파괴 후에도 2차 거동하고, 평평한 형태로 적용되며 두 배 변위를 갖는 댐퍼 모델을 제안한다. 변형이 크게 발생하는 상황에도 적합한 보강공법을 제안 및 실험하기 위해 변형능력이 탁월한 목구조 건축물로 선정하였다. 실험 결과, 모든 시험체에서 내력 상승효과와 2차 거동을 통한 붕괴방지를 확인하였다.

안전도시 프로그램을 효율적으로 운영하기 위해서는 중앙정부가 재정적 지원을 하여 범국민적 관심을 불러일으켜야 하고, 지방자치단체는 안전도시 운영조례 등을 제정하는 작업이 이루어져야 하며 경찰과 대학이 서로 경학교류 협력체제를 구축하는 작업이 해결되어야 한다. 이러한 작업이 선행된 후 안전도시 프로그램의 운영방향은 첫째, 지역사회에 소재하고 있는 시(군․구)청, 경찰서, 교육청, 소방서, 대학, NGO 등의 유관기관이 범죄예방의 협력적 네트워크를 구축해야 한다. 둘째, 범죄기회의 감소, 범죄자 검거위험의 증대, 범죄로 인한 보상의 감소, 죄책감이나 수치심 유발 등의 범죄예방전략을 수립해야 한다. 셋째, 환경설계를 통한 범죄예방, CCTV의 설치운용 등 공학적, 과학적 기법을 이용한 하드웨어 프로그램과 시민경찰학교, 청소년폴리스 아카데미, 성폭력예방교실, 실버안전지킴이 프로그램 등 교육이나 상담을 통한 소프트웨어 프로그램을 운영하여야 할 것이다. As precondition to operate safe city program efficiently, we must arouse a nation interested in central government's financial assistance and local government's enactment of safe city operation ordinance and establishment of police-university cooperation system. After these condition is solved, safe city program is administered as follows. First, related agency, such as city hall, police station, office of education, fire station, university, NGO, must establish the cooperative network of crime prevention. Second, we must work our strategy, such as reducing crime opportunity, Increasing perceived risks, reducing anticipated rewards, inducing guilt or shame. Third, we must operate hardware program, such as crime prevention through environmental design, CCTV and software program such as citizen police academy, juvenile police academy, sexual assault prevention program, silver safety guard.

조선후기 임실현 양반사회의 지속과 변화-『임실향안』, 『임실 청금안』을 중심으로-
장석현 조선시대사학회 2023 朝鮮時代史學報 Vol.- No.105
This paper explores the composition of the local yangban society in Imsil-hyeon during the late Joseon period. Using a case study approach, the study analyzes the lineages, surnames, and trends in hyangim and gyoyim recorded in Imsil-hyang-an and Imsil-cheong-geum-an. The findings suggest that five surnames, including Cheongju Han, Jeonju Yi, Hamyang Park, Hyeonpung Gwak, and Yeosan Song, dominated the registration of hyang-an from the 17th century to the early 18th century. However, this trend gradually eased in the mid-18th century to the late 19th century, with Cheongju Han and Jeonju Yi becoming more concentrated in the registration of cheong-geum-an. Other surnames attempted to be included in the dominant trend at a specific time, and this attempt became more pronounced in the 19th century, showing a similar registration rate to the previously dominant surnames. Furthermore, this study examines the trends in Hyangim and Gyoyim and shows that they were also concentrated on specific surnames such as Cheongju Han and Jeonju Yi. Cheongju Han is examined as a representative example of how they concentrated hyangim and gyoyim on their own ancestor to solidify their representation in the local society. In conclusion, although specific surnames dominated the registration of hyang-an and cheong-geum-an, and the trends in hyangim and gyoyim in the yangban society in Imsil, attempts were made to include other surnames in the dominant trend at specific times. Thus, while the yangban society in Imsil-hyeon maintained a trend of concentration on specific surnames in various aspects, there were also internal trends of change.
