국제교육과정(IBDP) 내 외국어로서 한국어 교육과정 특성 연구
박진욱(Park, Jin-Wook) 한국어문학회 2018 語文學 Vol.0 No.140
The proposal of this study is to analyze the aim and content of education through the lens of Korean Language Education as a Foreign Language in the course of International Baccalaureate Diploma Program(IBDP). Based on these results, we can further discuss the validity of Korean Education as a Foreign Language. The study examined the global direction and principle of IBDP which represents the high school course in the International Baccalaureate, particularly analyzing the aim and content of the foreign language acquisition part. Analysis results suggested that the set point of the start and end were too high. Contents of each part were different from the general foreign language acquisition. Concretely, the level of expression part was high and language usage that underline thinking power was much more supported than communication on the general situation. Consideration of these contents are important, although they lacked educational references which would actualize these guidelines in regards to teaching and learning. Further intensive discussion about the problems raised in this study is needed for further understanding.

The performance of in-line duct fan depends on the design parameters of impeller and guide vane such as sweep back angle of impeller hub, guide vane angle etc. In this study four kinds of impellers having different sweep back angles, $0^{\circ}$, $17.5^{\circ}$, $35^{\circ}$, $52.5^{\circ}$ with 8 guide vanes, and different guide vane angles, $15^{\circ}$, $30^{\circ}$, $45^{\circ}$ were selected and their performance measured to investigate the effects of design parameters. The results show that both sweep back angle of impeller hub and the guide vane angle have large effect on the efficiency. Especially, it was found that the mixed flow impellers having sweep back angle between $17.5^{\circ}$ and $35^{\circ}$ gave good performances for in-line duct fan.

The changes in the electrical characteristics of CMOS ICs due to coupling with a narrow-band electromagnetic wave were analyzed in this study. A magnetron (3 kW, 2.45 GHz) was used as the narrow-band electromagnetic source. The DUT was a CMOS logic IC and the gate output was in the ON state. The malfunction of the ICs was confirmed by monitoring the variation of the gate output voltage. It was observed that malfunction (self-reset) and destruction of the ICs occurred as the electric field increased. To confirm the variation of electrical characteristics of the ICs due to the narrow-band electromagnetic wave, the pin-to-pin resistances (Vcc-GND, Vcc-Input1, Input1-GND) and input capacitance of the ICs were measured. The pin-to-pin resistances and input capacitance of the ICs before exposure to the narrow-band electromagnetic waves were $8.57M{\Omega}$ (Vcc-GND), $14.14M{\Omega}$ (Vcc-Input1), $18.24M{\Omega}$ (Input1-GND), and 5 pF (input capacitance). The ICs exposed to narrow-band electromagnetic waves showed mostly similar values, but some error values were observed, such as $2.5{\Omega}$, $50M{\Omega}$, or 71 pF. This is attributed to the breakdown of the pn junction when latch-up in CMOS occurred. In order to confirm surface damage of the ICs, the epoxy molding compound was removed and then studied with an optical microscope. In general, there was severe deterioration in the PCB trace. It is considered that the current density of the trace increased due to the electromagnetic wave, resulting in the deterioration of the trace. The results of this study can be applied as basic data for the analysis of the effect of narrow-band high-power electromagnetic waves on ICs.

협대역 고출력 전자기파로 인한 CMOS IC에서의 오동작 특성 연구
박진욱,허창수,서창수,이성우,Park, Jin-Wook,Huh, Chang-Su,Seo, Chang-Su,Lee, Sung-Woo 한국전기전자재료학회 2016 전기전자재료학회논문지 Vol.29 No.9
This study examined the malfunction mode of the HCMOS IC under narrow-band high-power electromagnetic wave. Magnetron is used to a narrow-band electromagnetic source. MFR (malfunction failure rate) was measured to investigate the HCMOS IC. In addition, we measured the resistance between specific pins of ICs, which are exposed and not exposed to the electromagnetic wave, respectively. As a test result of measurement, malfunction mode is shown in three steps. Flicker mode causing a flicker in LED connected to output pin of IC is dominant in more than 7.96 kV/m electric field. Self-reset mode causing a voltage drop to the input and output of IC during electromagnetic wave radiation is dominant in more than 9.1 kV/m electric field. Power-reset mode making a IC remained malfunction after electromagnetic radiation is dominant in more than 20.89 kV/m. As a measurement result of pin-to-pin resistance of IC, the differences between IC exposed to electromagnetic wave and normal IC were minor. However, the five in two hundred IC show a relatively low resistance. This is considered to be the result of the breakdown of pn junction when latch-up in CMOS occurred. Based on the results, the susceptibility of HCMOS IC can be applied to a basic database to IC protection and impact analysis of narrow-band high-power electromagnetic waves.

본 논문은 기존의 총 송전용량 결정에 있어서 고려하기 어려웠던 과도 안정도 제약을 판별법을 적용하기 위해 2단계 계산 기법을 이용하여 보다 용이하게 적용하였다. 총 송전용량을 계산하기 위한 방법으로 첫 번째 단계에서는 RPF(Repeated Power Flow) 방법을 이용하여 전압과 열적한계를 판별하고, 두 번째 단계에서는 첫 번째 단계에서 결정된 총 송전용량이 시스템의 과도 안정도 조건의 위반여부를 판별하여 시스템의 총 송전용량을 결정하였다. This paper presents a method to assess total transfer capability(TTC) considering transient stability. TTC is limited not only by the violation of system voltage and thermal limits, but also restricted by transient stability limit, TTC calculation is divided into two processes. The frist step is to calculate TTC without considering the transient stability constraint by using repeated power flow(RPF) method. The second step is to perform transient stability analysis based on TTC calculation in the frist step.

본 연구는 독도가 대한민국 국민에게 특별한 의미를 갖는 지역이기 때문에,『국가경관이미지』를 갖고 있을 것이라는 가설을 증명하기 진행되었다. 이를 위해 내국인 대학생 51명과 외국인 대학생 44명을 대상으로 어의척도 설문조사를 실시하고 통계분석을 실시하였다. 그 결과 내국인 남녀간에는 큰 차이는 없는 것으로 나타났다. 그렇지만 [독도전체 경관사진]에 대해서는 “상당히 혹은 매우 귀중하고 인상적인 동시에 신비롭고 상징적이다”라는 이미지를 갖고 있었다. 이것은 여타 국립공원의 자연경관에 대한 반응들에서는 찾아 볼 수 없는 독도 특유의 이미지들이다. 한편, 내국인과 외국인의 응답 결과는 모든 변수에서 큰 차이를 보였다. 특히 [독도전체 경관사진]에 대해서 몇몇 경관형용사들 [인상적이다(1.41), 신비롭다(1,25), 상징적이다(1.00), 귀중하다(0.98), 친근하다(0.95), 아름답다(0.93), 흥미롭다(0.85)]은 내외국인 응답자들간 뚜렷한 차를 보였다. 바위 이름 자체에 국가경관이미지와 관련된 이름을 가진 바위들[한반도바위(0.57)]와 [독립문바위(0.51)]에 대해서도 내외국인 응답에 상당한 차이를 발견할 수 있었다. 요인분석 결과 도출된 세 가지 주요 요인가운데 첫 번째 요인은 국가경관이미지, 두 번째 요인은 독도의 자연성, 세 번째 요인은 독도의 공간감으로 나타났다. 본 조사 연구는 제한된 시간과 여건 속에서 한정적 조사연구가 수행되었지만 추후 좀 더 전 국민을 대상으로 한 확대 연구가 필요하다. 또한 CVM(조건부 가치측정법)에 의한 독도의 경제적 가치 재평가는 조속한 시일 내에 다시 수행될 필요성이 있다. This study is conducted to prove a hypothesis that Dokdo Island has “National Landscape Image,” being a region with special meaning for Korean people. University students(51 Koreans and 44 foreigners) were surveyed on landscape images of Dokdo Island, and the statistical analysis of the survey responses was performed subsequently. The findings showed no substantial difference between the opinions of Korean men and women: Especially the photo of whole Dokdo was highly rated by Korean respondents as “considerably or very valuable and impressive, but also mysterious and symbolic at the same time.” These are unique images of Dokdo Island, which are not found in responses to natural landscape of other national parks. Meanwhile, there were significant contrasts between the responses of Koreans and foreigners in every variables. Some landscape adjectives used as semantic differential scale demonstrate remarkable differences between Korean and foreign respondents, particularly on the photo of whole Dokdo: impressive(1.41), mysterious(1.25), symbolic (1.00), valuable(0.98), intimate(0.95), beautiful(0.93), interesting(0.85). There were substantial differences in responses between Korean and foreigners on two rock islands, which have names related with some national image: The Korean Peninsula Rock(0.57) and Independence Gate Rock(0.51). Finally, three primary factors drawn from the factor analysis were (1) national landscape image, (2) natural characteristics of Dokdo Island, and (3) spatiality of Dokdo Island.

다문화 배경 학습자의 수학 문장제 수행력 향상을 위한 교육 방안
박진욱 ( Park Jin-wook ),노정은 ( Noh Jung-eun ) 우리어문학회 2017 우리어문연구 Vol.59 No.-
이 연구는 다문화 배경 학습자들의 초등학교 수학 문장제 활동의 수행력을 향상시키기 위한 연구로 수행력 강화를 위해 언어 교육적 방안을 모색해 보는데 목적이 있다. 문장제 활동을 해결하는 데에는 수학적 요인 뿐만 아니라 언어적 요인 또한 영향을 미친다. 이에 초등학교 3학년 수학 교과서에 제시되어 있는 수학 문장제 활동을 분석하여 특징 및 문제점을 파악하고자 하였다. 분석결과 수학 문장제에서는 저빈도 어휘를 사용하는 경우가 많았고, 문장 당 평균어절 수가 많아 문장이 복잡하게 구성되어 있음을 살펴볼 수 있었다. 또한 교과의 핵심 내용이 되는 수학 용어가 매 단원 제시되고 있어 수학 용어는 우선적으로 교육해야 함을 확인하였다. 이에 본고에서는 문장제 수행력을 강화하기 위해 단계별 접근이 필요하다고 보고 기초 연산 능력 배양 단계, 언어 적응력 강화 단계, 문장제 활동 실전 단계의 설정을 제안하였다. This study has aim of finding a linguistic way for students in multi-cultural family to improve mathematical performance capability facing with math word problems. To solve math word problems, students are not only influenced by mathematical factor, but also influenced by linguistic one. In this sense, we focused on the math word problems presented in the third-grade math book, and tried to find distinct features and problems of them. As a result, we found that vocabulary not mostly used and complicated sentences having many phrases were seen frequently. Also, mathematical terms presented in every chapter should be taught in advance because they are core contents. In this study, we propose a step approach for the students and set up three steps of basic calculation capability, enhancing their linguistic adaptability, and actual solving of math word problems.
