Objectives : The aim of this study is to assess the usage of diagnosis codes for somatic dysfunctions and the general characteristics of patients diagnosed with the code, by analyzing health insurance data provided by the Health Insurance Review & Assessment Service(HIRA) of Korea. This investigation is intended to outline future and willing to contribute to further use of diagnosis code and the approach of Oriental Medicine to somatic dysfunction. Materials and Methods : By analyzing HIRA data, those diagnosed with M99 codes, a code attributed to somatic dysfunction, were selected for analysis. Patients included were assessed for the relevant general characteristics, and the specific diagnostic criteria. The current usage rates and noteworthy characteristics of diagnostic codes of somatic dysfunctions were assessed. A comparative analysis between clinical departments and subcategories, and a comparative analysis to data of 2014 was conducted. Results : Patients given M99 codes constituted a small minority of all patients diagnosed in 2011 as shown by HIRA data. The codes were more frequently to older patients, females, outpatients, and those who filed for Health Insurance compensation. Medical institutions participating in the diagnosis were mostly primary care facilities, usually specializing in orthopedic(Western medicine sector) and internal medicine (Oriental Medicine sector). The most registered code in 2011 and 2014 was M995. The same trend can be observed in Oriental/Western medicine institutions and Public health center, on the other hand, between them, have some different patterns both 2nd and 3rd. Conclusions : This investigation is that of current usage of diagnostic codes of somatic dysfunction. HIRA insurance claim data was analyzed. Based on the current results, more precise diagnostic standards of somatic dysfunction are warranted. This study will provide a foundation for future Oriental Medicine approach to somatic dysfunctions.

사례분석을 통한 건설현장 화재위험도 평가 체크리스트 개발

신재권 ( Shin Jae-kwon ),신윤석 ( Shin Yoon-seok ) 한국건축시공학회 2021 한국건축시공학회지 Vol.21 No.1

건설현장에서는 화재사고 발생 시 대형재해로 이어질 수 있는 위험성이 매우 크다. 건설현장에서는 가연성 물질을 다수 사용하고 있으며, 화재사고 발화원이 되는 장비를 흔히 사용하고 있어 화재사고 위험이 항상 상존한다. 화재사고 예방을 위한 다양한 제도로 명시하고 있으나, 건설현장작업 특성에 적합한 예방제도를 적용하기에는 한계가 있으며, 기존 연구에서는 법령개선 및 화재사고 시 진압 문제관련 내용의 연구가 진행되었다. 이에 본 연구에서 화재사고 사례분석과 선행연구 고찰을 통해 화재위험도 평가 체크리스트를 제안하였다. 체크리스트의 현장 적용성을 검토해보기 위해서 국내 건설현장에서 발생한 2건의 화재사고사례에 적용하였다. 그 결과, 실제 화재 원인을 포함하여 추가적으로 화재원인이 될 수 있는 원인들을 규명할 수 있었다. 본 연구의 화재위험도 평가 체크리스트를 건설현장에서 활용한다면 실질적이고 효과적인 화재사고 예방뿐만 아니라 화재사고가 발생하더라도 인명피해를 최소화하는데 기여할 수 있을 것이다. On the construction site, there exists frequently a high likelihood that a fire accident can lead to a large-scale disaster. In the previous studies, the diverse outcomes have been focused on the improvement of relative statutes and tried to realize the suppression and confrontation of the fire accidents. In this study, the limitations on the site were identified through prior research reviews, and the fire risk assessment checklist was proposed through the analysis of the massive accident cases. The checklist was divided into the prevention and minimization steps and developed into 16 categories of total risk factors. According to the results from the cases applied in this study, if the installation status is checked, such as removing combustibles, and broadcasting facilities for evacuation are installed, it is expected that the casualties will be minimized or zeroed. By developing a fire risk assessment checklist, this study provides the implications of the theoretical and realistic fire accident prevention, and supports the ways to minimize the damage resulted from the fire accidents on construction sites. In the further, deriving universe and common items about repeated occurrences of a work type will be needed as a subsequent research.

곤충의 식물 섭식은 숲 재생 및 식물다양성 유지와 밀접한 상관을 나타냄에도 불구하고 우리나라에서 식물-곤충 상호작용에 대한 연구는 수행된 바 없다. 본 연구는 광릉숲 (9개소) 및 점봉산(10개소)의 참나무 성숙림에서 방형구 (100 ㎡) 내 교목종 치수를 대상으로 각 치수의 잎 수, 각 잎에서의 섭식 유형과 양 (엽면적에 대한 섭식의 비율, %)을 기록하여 6개 곤충 섭식 기능군의 유형과 비율을 분석하였다. 광릉숲 (n = 469) 및 점봉산 ( n = 363) 임내 치수의 평균 초식 비율은 각각 52.5% (잎 수 = 1,468) 및 46.9% (잎 수 = 1,236)로 나타났다. 광릉숲 섭식율은 팥배나무가 100 %로 가장 높았고, 졸참나무가 80.3 %로 가장 낮았다. 점봉산 섭식율은 당단풍이 97.1%로 가장 높았고, 층층나무가 78.5 %로 가장 낮았다. 잎의 초식 피해 비율은 광릉숲 (11.2 %) 및 점봉산 (5.7 %)로 광릉숲이 2배 높았다. 곤충류의 섭식 기능군 별 비율은 가장자리형 (44.2 %)이 가장 높은 빈도였으며, 천공형 (32.2 %), 천흡형 (23.1 %) 등의 순으로 높았다. 본 연구는 식물-곤충 상호작용 모니터링을 위한 하나의 선행연구로서 실시되었다. 우선, 섭식 곤충의 실체를 확인하는 것이 필요하다. 그리고 식생 재생에 대한 곤충의 역할, 즉 교목종의 생활사 (생장 및 사망)와 곤충 섭식의 상관성을 밝힐 수 있도록 대상 개체를 선정하고 관찰해야 한다. There were limited research on evolutionary ecology of plant-insect interaction in South Korea although forest regeneration and plant diversity were correlated with insect`s plant feeding. In this study, we analysed pattern and ratio of 6 insect feeding functional groups through observing type and amount of feeding on leaves of tree species seedling in mature oak forest of Gwangneung forest (GF, n = 469) and Mt. Jumbong-san (JB, n = 363). Mean herbivory ratio of seedlings was higher in GF (52.5 %, leaves n = 1,468) than that of JB (46.9 %, leaves n = 1,236). In GF, Sorbus alnifolia (100 %) exhibited the highest feeding ratio and Acer pseudosieboldianum(97.1 %) in JB. Proportion of feeding area of leaves in GF (11.2 %) was 2 folds higher than that of JB (5.7 %). Marginal feeding (44.2 %) was the most common type and higher in the order of hole feeding (32.2 %) and piercing and sucking in ratio of feeding functional group. As preliminary study on plant-insect coevolution, more clarification on feeding insect and relationship between seedling fatality and insect activities was required.

There are no population ecological research on the natural monument (No. 191) Jeju Cymbidium kanran in South Korea. In this study, we analyzed the population structure and fine-scale habitat affinity of C. kanran in Sanghyo-dong, Jejudo Island from Oct. 2013 to Feb. 2014. We observed total of 1,237 individuals (4,341 pseudobulbs) of C. kanran (989.6 population ha-1) within (1.25 ha) and only 17 (1.4%) individuals were inflorescent. In 60.9% of the entire populations, disease symptoms such as spots and blight leaves were observed. C. kanran populaton exhibited reverse-J shaped size distribution based on leaf area classes as individual size parameter. The three size related attributes of C. kanran (no. of pseudobulb rs=-0.159, no. of leaves rs=-0.148 and leaf arera rs=-0.114) and soil temperature revealed a negative relationship (p. 0.0001). Most of C. kanran (95.4%) were grown under Castamopsis cuspidata and spatially, C. kanran were strongly clumped at all distances. Population characteristics of C. kanran in the study area were likely originated from species habitat affinity and successional environment. Through this study, base line data for C. kanran`s habitat monitoring was established and conservation measures based on population characteristics were discussed.

여행 수요가 증가하고 각 항공사는 고객을 유치하기 위해 서비스뿐만 아니라 인테리어도 다변화하고 있다. 그 노력의 일환으로 국내에서는 항공기용 대형 Flexible OLED를 캐빈 내부에 설치하고, 다분할 동영상을 시현하는 시스템을 개발하고 있다. 본 논문은 임베디드 환경에서 Gstreamer, NTP를 사용한 동영상의 분할 및 동기화 방법과 항공기용 표준 메시지/비디오/오디오 인터페이스인 MQTT, ARINC 628 P3를 적용한 비디오 플레이어 설계와 구현에 대해 다룬다. 시험을 통해 약 0.1초의 이더넷 오디오 딜레이가 발생하는 성능상의 문제가 확인됐으나, 다분할 비디오 간 최대 0.3ms이내의 동기화가 가능함을 보였다. 본 연구를 통해 국내 기술로 개발된 대형 미디어 디스플레이 장치가 향후 항공기 인테리어 시장에 진출할 수 있을 것으로 기대된다. Travel demand is increasing and each airline is diversifying its interior as well as services to attract customers. As part of its efforts, South Korea is developing a system that installs large flexible OLEDs for aircraft inside the cabin and displays multi-division videos. This paper deals with the method of segmentation and synchronization of video using Gstreamer, NTP and the video player design and implementation with the standard video/audio interface for aircraft, MQTT, ARINC 628 P3. The test confirmed a performance problem with an Ethernet audio delay of about 0.1 seconds, but showed that synchronization between multi-division videos can be up to 0.3 ms. Through this study, it is expected that large media display devices developed with domestic technology will be able to enter the aircraft interior market in the future.
