신호철(申昊澈) ( Shin¸ Ho-cheol ) 한국어문교육연구회 2020 어문연구(語文硏究) Vol.48 No.4

본고는 개화기에 간행된 문법서를 대상으로 교수학적 접근을 시도하였다. 이 문법서들은 대체로 문법 연구서로서의 기능과 문법 교과서로서의 기능을 겸하고 있지만, 주로 문법 연구서로서의 기능에 초점을 두고 연구가 수행되어 왔다. 따라서 본고에서는 교수학적 접근을 위해 개화기 문법 교과서 6개를 선정하여, 교육 목표의 선정, 교육 대상 설정, 교육 내용 위계화라는 기준으로 분석해 보았다. 교육 목표의 선정에서는 ①리봉운의 경우만 명백하게 드러나고 있고, ⑥주시경의 경우는 국문의 중요성과 국문 사용의 필요성에 대하여 언급하고 있었다. 교육 대상 설정에서는 ①리봉운과 ③김희상은 신문의 광고문을 통해, ④유길준과 ⑥주시경은 자서(自序)를 통해 교육대상을 추론할 수 있었으며, ③김희상과 ⑤주시경의 경우 교과서 제목을 통해 확인할 수 있었다. 교육 내용 위계화에서는 훈민정음을 포함한 문자론 내용, 음운론, 품사 분류를 포함한 단어론, 문장의 성분과 종류를 포함한 문장론의 내용을 공통적으로 다루고 있었고, 교육 내용의 배열 분석 결과, ③김희상과 ⑤주시경은 ‘과(課)’ 단위를 두고 있었다. This study attempts korean educational approach about grammar textbooks which are published during the enlightenment period(1895~1910). Grammar books during the enlightenment period are known as taking two roles, grammar studies and grammar textbooks which contains education contents for grammar education. However, looking at the results of research on grammar books during the period of over a century, it can be seen that the studies were focused on the function of grammar studies. Therefore, this paper attempted to grasp the characteristics of grammar education in grammar textbooks during the enlightenment period and to seek the didactical meaning. For this, 6 out of 22 grammar textbooks were selected. And the criteria, subjects of education selection, objectives of education setting, and hierarchical differentiation of education contents, were set for didactical approach to the textbooks. In the objectives of education selection, only the case of ①Lee Bongwoon was clearly revealed, and the case of ⑥Ju Sigyeong was referring to the importance of Korean and the necessity of using Korean. In the subjects of education setting, ①Lee Bongwoon and ③ Kim Huisang could be inferred through advertisements in newspapers. ④Yu Guljun and ⑥Ju Sigyeong were able to infer the subjects of education through the author’s preface. In the case of ③Kim Huisang and ⑤Ju Sigyeong, the subjects of education was confirmed by explicitly revealing the school level in the textbook title. In the hierarchical differentiation of education contents, the contents of the study of writ ing including Hunminjeongeum, phonology, morphology including part-of-speech classification, and syntax including the sentence constituents and type of sentences were dealt with in common. And, as a result of examining the hierarchical differentiation of educational contents, ③Kim Huisang and ⑤Ju Sigyeong have a unit of ‘department’ that is different from the general table of contents.

Purpose: Human lung microbiome are reported to be associated with survival, and acute exacerbation in patients with idiopathic pulmonary fibrosis (IPF). However, composition and clinical impact of microbiobial communities in the IPF lung tissues are unknown. The study aimed to investigate the association between lung tissue microbiome and clinical outcome in IPF patients. Methods: This study included patients with IPF (n=20; 10 survivors and 10 non-survivors) and age- and sex-matched controls (n=20). The genomic DNA was extracted from human lung tissues and amplified using fusion primers targeting variable V3 and V4 regions of the 16S RNA genes with indexing barcodes. Results: The median follow-up period was 5.4 years. The mean age of IPF subjects was 63.3 years, and 65% were male. There were no significant differences in alpha diversity indices between IPF patients and controls, and between survivors and non-survivors among IPF patients. In IPF lung, the relative abundance of genus Lactobacillus, Paracoccus, and Akkermansia increased, whereas that of genus Caulobacter, Azonexus, Undibacterium decreased compared with that in controls. In IPF non-survivors, genus Streptococcus and Bifidobacterium significantly increased than those in IPF survivors. In IPF patients, forced vital capacity (FVC) showed positive correlation with relative abundance of genus Curvibacter (r = 0.590) and Thioprofundum (r = 0.458), and negative correlation with that of genus Anoxybacillus (r= - 0.509), Enterococcus (r = - 0.593), Akkermansia (r = - 0.505), and Clostridium (r = - 0.445). In the multivariate Cox analysis adjusted by age, sex, smoking, and FVC, the relative abundance of genus Streptococcus (hazard ratio [HR]: 1.993, p = 0.044), Sphingomonas (HR: 57.590, p = 0.024), and Clostridium (HR: 37.189, p = 0.038) were significantly associated with IPF mortality. Conclusions: Our results suggest that lung tissue microbial communities could affect disease severity and prognosis in patients with IPF.

풍동실험과 화재실험을 통한 열감지기의 동작특성에 관한 연구

Hocheol Ryu,Doohyun Kim 한국재난정보학회 2015 한국재난정보학회 논문집 Vol.11 No.2

열감지기는 화재시 발생되는 열을 감지하는 것으로 모든 소방대상물에 일반적으로 사용 되는 자동화재탐지설비의 중요한 핵심 요소이다. 열감지기는 스포트(spot)형과 분포형으로 구분되며, 스포트형에는 차동식과 정온식이 있다. 이러한 열감지기는 실제 화재시 작동시 간 및 작동온도 등 반응의 민감도에 따라 인명과 재산 손실에 큰 영향을 준다. 국내에서는 스프링클러 헤드제품에 응답시간지수를 도입하여 사용하고 있으나, 열감지기에 대해서는 현재 적용이 되어지지 않고 있으며, 반응의 민감도를 표시하는 응답시간지수의 도입이 필 수적으로 본 연구에서는 국내 생산된 정온식 스포트형 열감지기와 다이아프램형 및 반도체 형식의 차동식 스포트형 열감지기에 대하여 풍동실험 및 화재실험을 통하여 응답시간지수, 작동시간, 작동온도 등에 대하여 연구하였다. 응답시간지수를 적용한 열감지기를 설치하여 신속한 경보로 인한 국민의 생명과 재산손실을 줄이는데 도움을 주고자 한다. The heat detector detects heat in the fire and is an important core element of the automatic fire alarm system used generally for every fire prevention objects. The heat detector is distinguished in spot type and spread type and in spot type, there are differential and thermistor types. These heat detectors give a great influence on the loss of people and property according to the sensitivity of response such as operation time and operation temperature in actual fire and in overseas people apply it for the development of products that can be operated in the early stage of fire including certification, quality management, and comparison standard by introducing response time index through the theory of heat balance that considers the heat loss and ventilation tests. In Korea, the response time index is introduced and used in the head of sprinkler products, but it is not applied to the heat detector at present. It is necessary to introduce the response time index that shows the sensitivity of response of the heat detector the installation standard for the heat detector that the response time index is applied should be different according to the fire weight, danger degree of fire, and shape of buildings. Through this study, it tries to help reduce lives and property of people through the swift warning by installing detectors suitable for the building structure.

DEVELOPMENT OF A STEAM GENERATOR TUBE INSPECTION ROBOT WITH A SUPPORTING LEG

HOCHEOL SHIN,KYUNG-MIN JEONG,SEUNGHO JUNG,SEUNGHO KIM 한국원자력학회 2009 Nuclear Engineering and Technology Vol.41 No.1

This paper presents details on a tube inspection robotic system and a positioning method of the robot for a steam generator (SG) in nuclear power plants (NPPs). The robotic system is separated into three parts for easy handling, which reduces the radiation exposure during installation. The system has a supporting leg to increase the rigidity of the robot base. Since there are several thousands of tubes to be inspected inside a SG, it is very important to position the tool of the robot at the right tubes even if the robot base is positioned inaccurately during the installation. In order to obtain absolute accuracy of a position, the robot kinematics was mathematically modeled with the modified DH(Denavit-Hartenberg) model and calibrated on site using tube holes as calibration points. To tune the PID gains of a commercial motor driver systematically, the time delay control (TDC) based gain tuning method was adopted. To verify the performance of the robotic system, experiments on a Framatome 51B Model type SG mockup were undertaken.

실내화재에서의 열감지기 동작특성 분석

Hocheol Ryu 한국재난정보학회 2014 한국재난정보학회 논문집 Vol.10 No.4

소방대상물에서의 경보설비는 실내에 있는 사람들에게 화재를 최초로 알려주는 설비로써, 보 다 많은 사람들을 대피시킬 수 있도록 하는 매우 중요한 역할을 한다. 이에 자동화재탐지설비 와 같은 경보설비의 최초동작을 빠르게 하기 위한 연구가 필요하다. 이러한 자동화재탐지설비 에서 감지기의 동작은 설치위치와 화원의 위치에 따른 영향을 가장 많이 받는다. 그럼에도 불 구하고 국내의 감지기 설치 기준은 설치 위치와 화원의 위치는 중시하지 않고 면적과 높이에 따른 화재감지기 설치에 대한 사항만을 규정하고 있다. 따라서 본 연구에서는 실내에 열감지 기와 보를 설치하고, 일반적인 화재를 가정하여 5 개소의 화원을 발생시켜 설치된 감지기의 동 작시간을 측정하였고, 감지기의 설치위치와 화원의 위치를 고려한 화재실험을 통하여 열감지 기의 동작특성을 분석한 것으로 다음과 같은 결론을 얻었다. 열감지기는 벽면에 근접하게 설 치된 감지기에서 작동지연현상이 보였으며, 벽면에서 적어도 22cm 이상 이격해서 설치하여야 한다. 화원이 보 외측에 존재할 때 감지기는 보에서 55cm 이격한 거리에서 동작이 가장 빨랐 다. 또한 화원에 근접한 감지기와 가장 늦게 동작한 감지기의 동작시간의 차이는 피난거리로 환산하였을 때 최대 115 m 의 피난거리가 확보되는 것으로 나타났다. 이를 통하여 적합한 위치 와 적응성을 고려한 감지기의 선택은 피난개시 시간을 최소화시켜 줄 수 있는 것을 확인하였다. The first operation of alarm system starts at a detector. And the largest effect is produced on the operation of detector by the fire source position and installation position. Nevertheless, the Korean standard for the installation of detector only specifies matters of fire detector installation according to area and height, without consideration of installation position and fire source position. Therefore, this study carried out a fire test in consideration of detector installation position and fire source position (5 places) in order to minimize casualties owing to the fast operation of fire detector when a fire occurred. Considering that it took the longest time for a detector close to a wall to work in the results of this test, it was possible to find that a minimum clearance to the wall was required.

Hocheol Shin,Kyung-Min Jeong,Jeong-Joo Kwon 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10

This paper presents a snake robot moving in a small diameter pipe. A snake robot is a multi-linked modular robot. The snake robot, KAEROT-snake IV consists of 11 2-DOF actuator modules, a head, and a tail module. Each of the 2-DOF actuator modules has two small DC motors and worm gear boxes to increase the torque output and an embedded motor controller. The snake robot can move in a small diameter pipe with a sequence of holding motion as well as with a sinusoidal motion. Some modules holds the robot itself by pressing outward to induce friction while the other modules move forward/backward and hold the robot at a more front/rear position. A sequence of holding moves the robot forward/backward in a small diameter pipe.
