JOHN M. O’HARA,JAMES C. HIGGINS,WILLIAM S. BROWN 한국원자력학회 2009 Nuclear Engineering and Technology Vol.41 No.3

This study has identified human performance research issues associated with the implementation of new technology in nuclear power plants (NPPs). To identify the research issues, current industry developments and trends were evaluated in the areas of reactor technology, instrumentation and control technology, human-system integration technology, and human factors engineering (HFE) methods and tools. The issues were prioritized into four categories based on evaluations provided by 14 independent subject matter experts representing vendors, utilities, research organizations and regulators. Twenty issues were categorized into the top priority category. The study also identifies the priority of each issue and the rationale for those in the top priority category. The top priority issues were then organized into research program areas of: New Concepts of Operation using Multi-agent Teams, Human-system Interface Design, Complexity Issues in Advanced Systems, Operating Experience of New and Modernized Plants, and HFE Methods and Tools. The results can serve as input to the development of a long-term strategy and plan for addressing human performance in these areas to support the safe operation of new NPPs.

「이생규장전(李生窺墻傳)」과 「그 여자네 집」 함께 읽기를 통한 한문소설 수업 방안 모색

김하라 ( Kim¸ Ha-ra ) 한국한문교육학회 2020 한문교육논집 Vol.55 No.-

본고에서는 한문소설 강독 수업에서 학습자의 흥미를 유발하고 학습 효과를 제고하기 위해 비교 독서의 방법을 시도해 보았다. 김시습의 「이생규장전」과 박완서의 「그 여자네 집」이 그 비교 독서의 대상이 되었다. 각각 14세기와 20세기를 시간적 배경으로 삼은 이 두 작품의 남녀 주인공, 즉 이생과 최씨 그리고 장만득과 곱단은 저마다 용모가 준수하고 총명한 데다 문예 취향이 있는 인물들이다. 이들은 같은 마을에 살며 그 마을을 대표할 만한 아름답고도 이상적인 청춘남녀로 귀하게 여겨졌으며, 가족과 마을 사람들의 지지와 축복 속에 자연스럽게 가까워지게 되었다. 학생 신분의 두 남자 주인공이 옆구리에 책을 끼고 오가던 낯익은 통학길은 그들이 저마다 연인을 만나고 사랑을 가꾸어가는 장소가 되어 주었다. 그 장소는, 각각의 소설이 창작된 시간의 간극 500년을 뛰어넘어, 지금 북한의 황해북도 개성이라는 공간적 일치점을 갖는다. 요컨대 두 쌍의 청춘남녀, 그리고 그들을 사랑한 가족과 공동체는 모두 개성 사람인 것이다. 이 두 쌍의 청춘남녀의 행복한 사랑은 오직 짧은 시간 동안만 환하게 빛났을 뿐, 그 뒤에는 곧 길고 어두운 이별이 영원히 이어졌다. 이생과 혼인한 지 얼마 되지 않은 최씨는 1361년 홍건적의 침입 때 外賊의 겁탈에 저항하다 목숨을 잃었다. 만득과의 혼인을 기다리던 곱단은 1945년 ‘정신대’에 끌려가지 않기 위해 중년 남자의 재취가 되어 고향 마을을 떠났고 다시는 돌아오지 못했다. 두 주인공 여성은 전쟁과 외침에 수반되는 여성에 대한 성폭력을 피하는 과정에서 처참한 죽음, 혹은 죽음과 다름없는 희생을 당했다. 그리고 두 주인공 남성은 가장 사랑하는 사람을 영영 잃은 채 세상에 남겨졌으나 끝내 그 사람을 마음에 간직했다. 이처럼 주인공 남녀가 ‘짧은 만남과 긴 이별’을 겪었다는 점, 그리고 이들의 인연을 관통하는 가치가 사랑을 넘어선 信義라는 점이 또한 「이생규장전」과 「그 여자네 집」이 공유한 바라 할 수 있을 것이다. 창작시기 면에서 500년이 넘는 간극에도 불구하고, 이 두 한국소설은 이처럼 상당한 공통점을 가지고 있다. 이 점에서 학습자는 「그 여자네 집」을 디딤돌로 삼아 한문소설인 「이생규장전」 등장인물의 성격과 내면심리의 이해를 보다 구체화할 수 있다. 아울러 북한의 개성을 공간적 배경으로 삼은 이 두 작품의 공통점과 그 이유를 탐구하는 과정은, 한반도 주민의 당면 과제인 평화와 통일이라는 문제와 관련하여 시야를 열어나가는 데 도움이 될 수 있다. In this thesis, by comparing a Korean novel of the Joseon Dynasty with a modern Korean novel, I tried to find a method to induce the interest of learners and enhance the learning effect in the class reading Sino-Korean novels. Kim Si-seup's “Yisaeng peeks inside the fence” and Park Wan-seo's “Her House” are the objects of comparison. With the 14th and 20th centuries as temporal backgrounds, respectively, the male and female protagonists of these two novels, namely, Yisaeng and Lady Choi, and Man-deuk and Gopdan, each have a good appearance, intelligent, and literary taste. They lived in the same village and were regarded as precious as beautiful and ideal young men and women who could represent the village, and they naturally came close to the support and blessings of their families and villagers. The familiar commute road where two male protagonists of student status came and went with books on their sides became a place where they met their lover and made love. The place, beyond the 500-year gap in the time when each novel was created, has a spatial congruence point of Gaeseong in North Korea. In short, the two pairs of young men and women, and the family and community who loved them, are all Gaeseong people. The happy love of these two pairs of young men and women shone brightly only for a short period of time, and a long and dark farewell followed forever. The two female protagonists suffered a terrible death or a sacrifice equal to death in the process of avoiding sexual violence against women accompanying war and foreign invasion. And the two male protagonists were left in the world with their loved ones forever lost, but in the end they kept that person in mind. Despite the gap of more than 500 years in terms of creation period, these two Korean novels have such a great deal in common. In this respect, the learner can understand the character's inner psychology more specifically. Moreover, the learners who are residents of the Korean peninsula can advance to deep thoughts on the issue of peace and reunification of Korea.

Imaging Individual Proton-Conducting Spots on Sulfonated Multiblock-Copolymer Membrane under Controlled Hydrogen Atmosphere by Current-Sensing Atomic Force Microscopy

Hara, Masanori,Hattori, Daiki,Inukai, Junji,Bae, Byungchan,Hoshi, Takayuki,Hara, Masaya,Miyatake, Kenji,Watanabe, Masahiro American Chemical Society 2013 The journal of physical chemistry. B, Condensed ma Vol.117 No.14

<P>The proton-conductive spots on the membrane surface of sulfonated poly(arylene ether) multiblock copolymer were successfully imaged by current-sensing atomic force microscopy under hydrogen atmosphere at various temperatures and humidities. These spots should be connected to the proton-conductive paths inside the membrane. The average diameter of the spots was approximately 12 nm, consistent with the size of hydrophilic domains observed by transmission electron microscopy. The size of the proton-conducting spots was almost unchanged regardless of the temperature and humidity, whereas the number of the spots increased at higher humidity; the total area of the proton-conducting spots increased accordingly on the membrane surface. This increase in the conducting area at high humidity should be related to the bulk ionic conductivity measured by impedance spectroscopy.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpcbfk/2013/jpcbfk.2013.117.issue-14/jp312041c/production/images/medium/jp-2012-12041c_0011.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp312041c'>ACS Electronic Supporting Info</A></P>

Comparative Analysis on Positive Bias Stress-Induced Instability under High V<SUB>GS</SUB>/Low V<SUB>DS</SUB> and Low V<SUB>GS</SUB>/High V<SUB>DS</SUB> in Amorphous InGaZnO Thin-Film Transistors

Hara Kang,Jun Tae Jang,Jonghwa Kim,Sung-Jin Choi,Dong Myong Kim,Dae Hwan Kim 대한전자공학회 2015 Journal of semiconductor technology and science Vol.15 No.5

Positive bias stress-induced instability in amorphous indium-gallium-zinc-oxide (a-IGZO) bottom-gate thin-film transistors (TFTs) was investigated under high VGS/low VDS and low VGS/high VDS stress conditions through incorporating a forward/reverse VGS sweep and a low/high VDS readout conditions. Our results showed that the electron trapping into the gate insulator dominantly occurs when high VGS/low VDS stress is applied. On the other hand, when low VGS/high VDS stress is applied, it was found that holes are uniformly trapped into the etch stopper and electrons are locally trapped into the gate insulator simultaneously. During a recovery after the high VGS/low VDS stress, the trapped electrons were detrapped from the gate insulator. In the case of recovery after the low VGS/high VDS stress, it was observed that the electrons in the gate insulator diffuse to a direction toward the source electrode and the holes were detrapped to out of the etch stopper. Also, we found that the potential profile in the a-IGZO bottom-gate TFT becomes complicatedly modulated during the positive VGS/VDS stress and the recovery causing various threshold voltages and subthreshold swings under various read-out conditions, and this modulation needs to be fully considered in the design of oxide TFT-based active matrix organic light emitting diode display backplane.

The Correlation between Social Media Use and Social Anxiety

Hara Koo,Gidong Koo 한국경영학회 2022 한국경영학회 통합학술발표논문집 Vol.2022 No.8

Because many people use social media, they get influence by it, such as mental disorders. The purpose of this study is to determine whether social media usage affects social anxiety. We first hypothesized that exposure to image-conscious feeds would increase social anxiety, especially state anxiety, through the previous study. We showed feeds being centered on people to the experimental group and feeds such as animals and foods to the control group to measure the difference between social anxiety levels. To avoid mental disorders such as anxiety, people should reduce their social media use.

Predicting Double-Blade Vertical Axis Wind Turbine Performance by a Quadruple-Multiple Streamtube Model

Hara, Yutaka,Kawamura, Takafumi,Akimoto, Hiromichi,Tanaka, Kenji,Nakamura, Takuju,Mizumukai, Kentaro Korean Society for Fluid machinery 2014 International journal of fluid machinery and syste Vol.7 No.1

Double-blade vertical axis wind turbines (DB-VAWTs) can improve the self-starting performance of lift-driven VAWTs. We here propose the quadruple-multiple streamtube model (QMS), based on the blade element momentum (BEM) theory, for simulating DB-VAWT performance. Model validity is investigated by comparison to computational fluid dynamics (CFD) prediction for two kinds of two-dimensional DB-VAWT rotors for two rotor scales with three inner-outer radius ratios: 0.25, 0.5, and 0.75. The BEM-QMS model does not consider the effects of an inner rotor on the flow speed in the upwind half of the rotor, so we introduce a correction factor for this flow speed. The maximum power coefficient predicted by the modified BEM-QMS model for a DB-VAWT is thus closer to the CFD prediction.

Nonlinear behavior of R/C cooling tower shells

Hara, Takashi,Kato, Shiro,Ohya, Makoto Techno-Press 1997 Structural Engineering and Mechanics, An Int'l Jou Vol.5 No.5

In this paper the ultimate strength of the R/C cooling towers, which have initial imperfection and pre-cracked elements, is analyzed. The initial geometric imperfections arise from the unavoidable inaccuracies under the construction and the pre-cracks are assumed to be produced by the temperature stress gradients or cyclic loading under wind pressure and/or earthquake load. Both effects are strongly influenced on the strength of the R/C cooling tower shell structures. The reinforcing ratio is also the important factor to evaluate the ultimate strength of the R/C cooling tower shells. However we could not analyze these structures experimentally because of their large, analyses are the powerful schemes to evaluate the safety and reliability of these structures. The analyzed model is Port Gibson cooling tower shell. In the numerical analysis the geometric and material nonlinearities are taken into account.
