In this paper, we develop a explosion-proof LED lighting (Ex circuit) circuit of Explosion-proof LED Signal Lamp (Ex LSL) to utilize the core module of the explosion-proof Local Control System (Ex LCS) for offshore plant applications. And then analyzed its electrical, optical and thermal characteristics. Ex circuit was applied input voltage from AC/DC(12~254) V. In this experiments, stable light-on characteristics were confirmed by eyes for the every input voltages with min. 78,462 and max. $517,975cd/m^2$ of luminance. also Output current and output luminance was made proportional. Because the measured maximum surface temperature of Ex circuit was $54.23^{\circ}C$ at AC 48 V, Ex circuit was rated with T6 of temperature class. Finally, Ex circuit was shown stable light on characteristics under the $-50^{\circ}C$ and $60^{\circ}C$ during 12 hours of test period.

한국어 초급 학습자를 위한 PWIM 활용 운동 어휘장 교육 방안

정민주 ( Jeong Min Joo ) 숙명여자대학교 한국어문화연구소 2024 한국어와 문화 Vol.35 No.-

본 연구는 한국어교육에서 PWIM을 활용한 운동 어휘장 교수 모형을 개발하여 교육의 방안을 마련하는 데에 목적이 있다. PWIM은 ‘Picture Words Inductive Model’의 약자로, 학습자들이 한 장의 사진을 보고 어휘를 찾아내는 학습법이다. 선행연구를 분석한 결과 한국어교육에서 PWIM을 활용한 연구는 3건에 불과했으며, 일반화하기 어려운 결과를 보였으므로 효용성 있는 초급 학습자를 위한 시각 자료를 활용한 PWIM 교수 모형을 개발하고자 하였다. 모형 개발에는 어휘장 개념을 도입하였는데, 한 장의 시각 자료 안에 같은 어휘장에 해당하는 어휘들을 함께 제시하면 어휘장 내 유기적인 단어 이해에 도움이 될 수 있으며 어휘 확장에도 편리하다. 특히 운동 어휘장의 경우 초급 단계에서 학습하게 될 기초 어휘에 해당하는 어휘가 많으며 한 장의 사진으로 제시하여 교수ㆍ학습하기 용이하므로 PWIM을 활용한 수업에 적절하다고 판단하였다. 교육 방안 제시를 위해 한국어 교재 4종을 분석한 결과, 운동 어휘장만을 별도로 다루는 교재는 『세종한국어』뿐이었다. 교육 방안은 한국어 학습자 중 일반 목적 학습자를 대상으로 실제 수업에서 활용할 수 있도록 현장에서 사용되는 교재인 『세종한국어3』의 2과 ‘좋아하는 것’ 단원을 기반으로 하였다. 또한, 특강 형태가 아닌 정규 수업 50분 내에서 어휘와 문법을 모두 학습할 수 있는 교육 방안을 마련하였다. This study develops a teaching model using PWIM for sports lexical fields in Korean language education, focusing on beginners. To suggest the suitable method, four types of Korean textbooks were analyzed. The proposed method, based on Sejong Korean 3, integrates vocabulary and grammar for practical classroom use within a regular class.

In buildings on the indiscriminate redevelopment are being made by overlooking the relationship with surrounding landscape to create their own unique meaning, due to industrialization progressed rapidly with human needs of longing for something constantly. Selection and methods of two plans, conservation and utilization should be required, considering heritage values on industrial buildings which are being lost and aged in this redevelopment higher. The attempt for the use of modern industrial heritage becomes a hot topic, and several experimental challenges are being made. However, there are rather many cases of causing industrial buildings` depreciation and one-size-fits-all reproduction performance as it applies other examples as standards by recognizing the reproduction of modern industrial heritage as one trend, not focusing on the trend of the times or paradigm, what the times want. To minimize these problems, we focus on how to utilize industrial buildings beyond the importance of industrial buildings` reproduction, considering the quality of local residents` life as well as the expected effect obtainable due to security of local identity and reproduction of buildings, focusing on the concept of community design that offers and forms a way of community life as the design of shares based on unspecified individuals` common life. Community design`s core can be called to have diversity rather than undifferentiated unity by pursuing whole unification, since local residents become those who plan design and all people participate in it. In addition, community design achieves integration with other fields as an enlarged design area without limiting in an environmental area, by making indigenously natural characteristics combined with cultural factors in one context so that people may understand the flow of the place. The importance of effects acquired from modern industrial heritage`s reproduction has well-known, and the attempt for utilizing aged heritage as a new value and a function has constantly been made. Now, it`s time to focus on how long it lasts through this method, rather than modern industrial heritage`s reproduction itself. There can be a significance in this study in proposing methodological solutions on modern industrial heritage`s reproduction, not to cause depreciation of industrial buildings by contemporary trends and uniform regeneration performance, multifaceted research is needed for creative, effective development on modern industrial heritage which will occur constantly.

특수교육 저널: 이론과 실천 : "다감성적 스토리텔링"을 통한 중도,중복장애학생의 초기 문해 능력 분석

정민주 ( Min Joo Jeong ),이숙정 ( Suk Jeong Rhie ) 한국특수교육문제연구소 2015 특수교육저널 : 이론과 실천 Vol.16 No.3

영미언어권 및 독어권의 중도.중복장애 교육학에서 최근 국제적 이슈로 부각되고 있는 ‘다감각적 스토리텔링TM’’ 및 ‘다감성적 스토리텔링TM’’컨셉은 스토리텔링 등 문학 활동을 통해 해당 장애인의 초기 문해 능력 습득 및 범주 확장 뿐 아니라 문화 참여 및 자아실현에도 중점을 두고 있다. 이에 본 연구에서는 국내 전래동화「콩쥐팥쥐」를 다감성적 스토리텔링으로 개발하고 이를 중도.중복장애학생 3명에게 각 5회기 적용하여 이들의 초기 문해 능력 관련 반응행동을 긍정적 및 부정적 행동 양상으로 구분하여 살펴보고, 반응행동 변화의 의미를 모색하였다. 결국 중도 중복장애 학생에게 어려워 보이는 문학(동화)일지라도 이를‘다감성적스토리텔링’을 통해 이들의‘이해 양식(modus)’에 맞게 전달한다면, 이들 역시 이야기에‘접근’하여 맥락적으로(apprehensive)이해할 수 있으며, 이는 이들이 보이는 반응행동의 변화를 통해서도 알 수 있었다. 논의에서는 이들의 초기 문해 능력 역시 위와 같은 문학 활동을 통해확장될 수 있기에 문학을 접할 기회를 다양하게 제공하는 것이 필요하고, 이것이 곧 사회구성원으로서 문화 참여(cultural participation)에 이바지함을 강조하였다. In the field of education for people of profound intellectual and multiple disabilities(PIMD) of the UK and Germany has emerged MSSTTM and MSGETM in recent international issues. It focuses on early literacy ability, as well as cultural participation and self-realization of people with PIMD through the literary activities such as storytelling. This study aimed at examining the early literacy-related reactive behaviors of students with PIMD, when they are exposed to ``Mehrsinn Geschichten`` of the traditional fairy tale 「Kongji and Patzzi」. The subjects of the study included three students with PIMD. The ``Mehrsinn Geschichten`` of「Kongji and Patzzi」developed by this researcher was equally delivered to each of the students during five sessions. The students`` early literacy-related reactive behaviors were videotaped, recorded and then analyzed. The students`` early literacy-related reactive behaviors were analyzed based on the Affective Communication Assessment (ACA) on each of the students. The results were classified as: reactive behaviors according to sentence in each session; positive and negative reactive behaviors over entire sentences; and categories of positive and negative reactive behaviors over entire sentences. First, as for the students`` reactive behaviors according to sentence in each session, the students felt unfamiliar with the story at the beginning, but felt familiar later. Second, the reactive behavior of the entire story sentences were more or less by the rate of change and difference in student behavior. Positive action has increased as the session continued, the latter half showed a decline. On the other hand, negative effects act decreased as the session continued, the latter half showed a slight increase. Third, categories of positive and negative reactive behaviors over entire sentences included facial expressions, gestures, movements, and vocalizations. This study found that students with PIMD can acquire earlyliteracy ability.

Modern industrial heritages just like an important heart containing the image and identity of cities should not be treated as a headache any more. Active recycling of such buildings can create unique, interesting and innovative space for modern service functions. In order to seek for ways to combine the past and present, instead of urban growth disconnected with the past, now studies on recyclability of domestic abandoned factories are valuable, and we should pay more attention to surrounding modern industrial buildings. In the results of researching domestic cases, we found economic, cultural, regional, symbolic and architectural significance of recycling from cases currently under way even though there are not many cases of recycling abandoned factories compared to the number of overall modern industrial heritage. Still, attempts to use new space continuously become the topic of conversation. Through researches on foreign cases, we should know the correct significance of recyclability. However, we should not take the existing foreign cases as a standard after simply considering recycling of industrial heritages as a trend. Instead, we should focus on the flow of the time, paradigm and what is really desired in this era. Just for the instant growth of cities, we should not forget the past containing our history. Researches on recyclability of modern industrial buildings should be continued in the future.

The purpose of this study was to investigate the antioxidative effects of Mori Cortex Radicis powder and to determine the optimal mixing ratio of Mori Cortex Radicis powder and water in the preparation of bread. The optimal sensory composite recipe was determined by producing bread with different levels of Mori Cortex Radicis powder and water. The analysis was performed using response surface methodology and a sensory evaluation was performed with the data. Ten experimental recipes, including two with reference points in the composition, were selected. In terms of the antioxidative effects of Mori Cortex Radicis powder, the IC50 for total phenolic content and DPPH free radical scavenging activity were 149.56 GAE/g dry powder and 137.77 /mL respectively. Measurement results of the mechanical properties showed differences in volume (p<0.05), baking loss (p<0.05), yellowness (p<0.01), lightness (p<0.01), redness (p<0.01), hardness (p<0.01) and springiness (p<0.05). The sensory measurements showed significant values for color (p<0.05), appearance (p<0.05),flavor (p<0.01), taste (p<0.01), and overall quality (p<0.01). Overall, based on numerical and graphical methods, the optimal formulation was determined to be 21.16 g of Mori Cortex Radicis powder and 372.47 g of water.

특별교부금 국가시책사업 평가의 실태와 개선과제

김지하(Kim Ji Ha),정민주(Jeong Min Joo) 한국교육재정경제학회 2016 敎育財政 經濟硏究 Vol.25 No.4

특별교부금 국가시책사업 평가는 2016년 1월 12일 지방교육재정교부금법 시행령 제3조의2(특별교부금 교부 대상 국가시책사업의 평가 등)가 신설되면서 본격적으로 실효성을 가지고 시행되게 되었다. 본 연구에서는 정책평가의 이론적 관점에서 제도가 확립되기 전의 특별교부금사업 평가를 분석하였다. 2010년부터 2015년까지의 특별교부금 국가시책사업 평가제도 운영실태와 성과를 살펴보고, 개선과제를 제안하였다. 평가의 목적은 각 연도별 예산과 사업 규모에 따라 다소 변동이 있었으나, 주로 사업의 추진경과와 성과에 대한 점검과 다음연도 사업 및 예산 규모 선정에 반영하기 위한 환류의 성격이 강하게 나타났다. 평가대상 사업은 초기에 비해 점차 확대되어, 2015년에는 6개 소위원회에서 29개 정책분야에 해당하는 사업을 대상으로 평가를 진행하였다. 평가방법에 있어서는 서면평가, 설문조사, 현장평가, 종합평가를 활용하여 다각적 방면에서 사업을 분석·파악하고자 하였다. 평가지표로는 사업의 계획-집행-성과(결과)-환류의 4개 영역에 걸쳐 세부적인 지표가 설정되었고, 영역별 배점은 연도별로 차이가 있지만 신규사업의 수가 점차 줄어든 최근에는 성과의 비중이 약 50%로 증가하는 양상을 보였다. 또한 특별교부금 국가시책사업 평가가 정착되면서 최근 3년간 성과지표로서 투입지표보다 과정·산출지표와 결과지표가 늘어나고 있어 사업평가가 성과관리 체계 확립에 긍정적인 영향을 미치는 것으로 파악되었다. 이밖에도 특별교부금 국가시책사업의 평가등급과 예산증감률에 영향을 미치는 요인을 분석한 결과, 평가등급이 높은 사업일수록 성과지표로서 투입·과정지표가 아닌 결과지표를 설정한 것으로 나타났다. 또한 전년도 대비 사업비 증감률은 사업연도가 최근일수록, 사업연차가 길어질수록 감소하는 것으로 나타났으며, 사업비의 절대적 규모가 클수록 증감률은 크게 나타났다. 그러나 전년도 특별교부금 사업 평가결과는 차년도 예산편성에 통계적으로 유의미한 영향을 주지는 않았다. 이상의 결과를 토대로 평가제도의 개선과제로는 평가의 타당성과 신뢰도 제고를 통한 평가체계 확립, 피평가자의 적극적 참여를 유도하기 위한 인센티브 제도 수립, 평가결과를 다음연도 사업계획에 반영할 수 있는 적극적 환류체계 마련 등이 제안되었다. The evaluation for National Policy Project given Special Subsidy has been come into force with the new settlement of enforcement decree 2 of Article 3(the evaluation for National Policy Project which is the object of Special Subsidy recipient etc.) on January 12thin 2016.This research has analyzed the evaluation for the Project of Special Subsidy before establishing the system in theoretical perspective of policy evaluation and has suggested tasks for improvement after considering operating status and achievement of the evaluation for National Policy Project Given Special Subsidy from 2010 to 2015. Although the purpose of the evaluation has been changed somehow, it shows mainly the propulsion progress of the project, inspection for the accomplishment and the nature of feedback strongly to be reflected to selection of the project of next year and the scale of the budget. The project has been enlarged gradually than the early years, it’s been evaluated all projects of 29 policy fields in 6 subcommittees in 2015. In terms of the evaluation method, multilateral ways such as documentary evaluation, survey, field evaluation and comprehensive evaluation are used to analyze and understand the project. From the evaluation of the National Policy Project given Special Subsidy, the accomplishment index of the project for recent 3 years has been improved. Since the number of index for the process·production and result has been increased, the support to establish a continuous accomplishment management system is needed. Also, as the relation between the evaluation result and the budget of National Policy Project given Special Subsidy has been analyzed, no big difference of budget change for next year is in high level, but big decrease rate of budget is in low level and it is analyzed as the well operated feedback function of evaluation. In revised enforcement decree of Subsidy Law, since the reduction and abolition of the business for the result of the evaluation is stipulated, the feedback system for the result of future evaluation will be strengthened more.

WLAN 시스템에 적용 가능한 결함 접지 구조를 갖는 이중대역 평면형 모노폴 안테나 설계 및 제작

강병남(Byeong-Nam Kang),이승엽(Seung-Yeop Rhee),정민주(Min-Joo Jeong),최도민(Domin Choi),김남(Nam Kim) 한국전자파학회 2018 한국전자파학회논문지 Vol.29 No.1

본 논문에서는 WLAN(Wireless Local Area Network) 시스템에 적용 가능한 결합 접지 구조(DGS)를 갖는 마이크로스트립 급전 방식의 모노폴 안테나를 제작하였다. 제안된 안테나는 결함 접지 구조를 이용하여 이중 대역이 나타나게 하였으며, 모노폴 안테나는 두께를 단계별로 줄여가며 임피던스 정합을 용이하게 하였다. 44 × 51 × 1.6 ㎣의 크기로 모노폴 안테나 및 접지면의 크기를 변화시켜가며 최적화하여 WLAN의 2.4 ㎓ 대역과 5 ㎓ 대역을 만족할 수 있도록 하였다. FR-4기판을 사용하여 제작 및 측정한 결과 VSWR(Voltage Standing Wave Ratio) 2 이하를 기준으로 210 ㎒(2.29~2.50 ㎓)와 900 ㎒(5.05~5.95 ㎓)의 대역폭을 얻었고 전방향성의 방사패턴을 얻었다. In this paper, a dual-band microstrip-fed monopole antenna with a DGS(defected ground structure) for WLAN(wireless local area network) applications is presented. The antenna consists of a monopole and a defected ground, which were etched on both sides of the FR-4 substrate. The defected ground structure was used to obtain the dual band, while the step-by-step reduction in the monopole width was used to improve the impedance matching of the antenna. The antenna has an overall compact size of 44 × 51 × 1.6 ㎣, which was optimized by varying the size of the monopole and the ground plane such that it may resonate at the 2.4 ㎓ and 5 ㎓ bands of the WLAN. The measurement results showed that the antenna operates in the frequency band of 210 ㎒(2.29~2.50 ㎓) and 900 ㎒(5.05~5.95 ㎓) for a VSWR under 2, and showed omnidirectional radiation pattern at all desired frequencies.
