개화기(開化期) 문법(文法) 교과서(敎科書)의 교수학적(敎授學的) 연구(硏究)
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.
Proactive Task Execution Using Data Sharing and Event Transition among Personal Devices
( Hocheol Jeon ),( Taehwan Kim ),( Joongmin Choi ) 한국인터넷정보학회 2010 KSII Transactions on Internet and Information Syst Vol.4 No.6
This paper proposes an intelligent technique for data sharing and event transition among personal devices including smart phones, laptops, and desktops. We implemented the PES (Personal Event Service) system that proactively executes appropriate tasks across multiple devices without explicit user requests by sharing the data used by the user and recognizing user intention based on the observed actions of the user for specific devices. The client module of PES installed on each device monitors the user actions and recognizes the intention of the user. The server provides data sharing and maintenance for clients. The connection between client and server is established by Java RMI (Remote Method Invocation). A series of experiments were performed to evaluate user satisfaction and system accuracy, and the results showed that the PES system can proactively provide appropriate, personalized services with a high degree of satisfaction to the user in an effective and efficient manner.
A Simple Static Noise Margin Model of MOS CML Gate in CMOS Processes
Hocheol Jeong,Jaehyun Kang,Kang-Yoon Lee,Minjae Lee 대한전자공학회 2017 Journal of semiconductor technology and science Vol.17 No.3
This paper presents a simple noise margin (NM) model of MOS current mode logic (MCML) gates especially in CMOS processes where a large device mismatch deteriorates logic reliability. Tradeoffs between speed and logic reliability are discussed, and a simple yet accurate NM equation to capture process-dependent degradation is proposed. The proposed NM equation is verified for 130-㎚, 110-㎚, 65-㎚, and 40-㎚ CMOS processes and has errors less than 4% for all cases.

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.
The Declining Rebound Effect Revisited
( Hocheol Jeon ),( In-moo Kim ),( Sungro Lee ) 한국환경경제학회, 한국자원경제학회 ( 구 한국환경경제학회 ) 2017 한국환경경제학회 학술발표논문집 Vol.2017 No.하계
This paper estimates the rebound effect for motor vehicle using a time-varying cointegrating regression model. We consider U.S. national data for 1976-2015. Our models allow the rebound effect to evolve over time and especially the rebound effect is modeled as a smooth function of time. This approach is motivated by some recent studies that report some evidence of declined rebound effect. Our estimates for time-varying rebound effect have shown a significant downward trend for the sample period.
Aerial Working Environment Monitoring Robot in High Radiation Area
Hocheol Shin,Chang-Hoi Kim,Yong-Chil Seo,Eom Heung-Seop,Youngsoo Choi,Myoungho Kim 제어로봇시스템학회 2014 제어로봇시스템학회 국제학술대회 논문집 Vol.2014 No.10
This paper describes the development of a robot monitoring an aerial working environment in a high radiation area such as the Calandria face at a PHWR (pressurized heavy water reactor) of a nuclear power plant. The robot consists of three main parts: a mobile platform, a telescopic mast, and a mission tool. To access the target place across the guide rail ditch of a shielding door, the mobile platform is equipped with two front rubber wheels, two rear omni-wheels, and four flippers. The telescopic mast installed on the platform is able to lift up the mission devices to the height of 10 m. The mission devices are a radio hardened camera, a leak detecting sensor, a dosimeter detecting high radiation level, and a RAM operating device of a fuel exchange machine. In addition, a control system considering the emergency was developed.
