열충격 시험을 통한 MLCCs SAC305 무연 솔더 접합부의 IMCs 성장과 접합특성 저하에 관한 연구
정상원,강민수,전유재,김도석,신영의,Jung, Sang-Won,Kang, Min-Soo,Jeon, Yu-Jae,Kim, Do-Seok,Shin, Young-Eui 한국전기전자재료학회 2016 전기전자재료학회논문지 Vol.29 No.3
The bonding characteristics of MLCCs (multi layer ceramic capacitor, C1608) lead-free solder (SAC305) joints were evaluated through thermal shock test ($-40^{\circ}C{\sim}125^{\circ}C$, total 1,800 cycle). After the test, IMCs( intermetallic compounds) growth and cracks were verified, also shear strengths were measured for degradation of solder joints. In addition, The thermal stress distributions at solder joints were analyzed to compare the solder joints changes before and after according to thermal shock test by FEA (finite elements analysis). We considered the effects of IMCs growth at solder joints. As results, the bonding characteristics degradation was occurred according to initial crack, crack propagations and thermal stress concentration at solder-IMCs interface, when the IMCs grown to solder inside.

정상원(Jung, Sang-Won) 한국사회체육학회 2017 한국사회체육학회지 Vol.0 No.68
This study is designed to research the educational connection research of knowledge, virtue, physical and thought of Nammyeong(南冥) Jo Sik(曺植). On the basis of the results analyzed in this study, the conclusion could be drawn as follows. Firstly, Nammyeong taught practical life method through physical action. When the nation was in crisis, he taught war method and war skill to pupils and taught actual life pattern. Secondly, Nammyeong thought Gyeong[敬] and Yui[義] important with practical thought of people and thought practical doing more important than theoretical background screen for overcoming modern society crisis. Thirdly, Toegye(退溪) Yi Hwang(李滉) showed theoretical pattern for actual life application of Gyeong[敬]and Yui[義], whereas Nammyeong showed practical pattern for actual life application of Gyeong[敬] and Yui[義]. Fourthly, When Nammyeong taught pupils, he understand the gift of learners according to each one’s ability and aimed learner centered education. Fifthly, The relationship of self realization and existence theoretical problem related to physical activity is to develop the perfect people through cultivation of knowledge, virtue and body with Gyeong[敬]and Yui[義] of Nammyeong. Sixthly, the emphasis of sportsmanship in connection with Gyeong[敬]and Yui[義] is the foundation method for ethical problem solution of sport. The cultual variable to practice, drill and learning of Gyeong[敬]and Yui[義] are sport and physical education activity.

정상원(Sang Won Jung) 한국사회체육학회 2013 한국사회체육학회지 Vol.0 No.52
This study was designed to establish the relationship of lifestyle and learning ability according to exercise type of children. In this study, life style questionnaire and learning ability testpaper were used to study empiri-cally relationship of lifestyle and learning ability according to exercise type of children. The 118 subjects were selected from 7 elementary school(soccer 28, volleyball 30, baseball 30, non sport 30). The 5% level of significance was used as the critical level for acception of the hypothesis in the study. On the basis of the results analyzed in this study, the conclusion could be drawn as follows. 1. The learning action comparison of indoor sport and outdoor sport appeared to nonsignifant difference but, the vocabulary ability, reasioning ability, arichmetic ability, spatial ability related to learning ability showed signifant difference. Generally, Indoor sport children appeared to better than outdoor sport children, the vol-leyball children appeared to better than the soccer children, the baseball children in learning ability. 2. According to sport type, the vocabulary ability, reasioning ability, arichmetic ability, spatial ability, con-centration ability showed signifant difference. The vocabulary ability appeared to order of nonsport, volleyball, baseball, soccer. In the reasioning ability and spatial ability, the volleyball children appeared to better than the soccer children, the baseball children, nonsport children. 3. The self control, nihility, sport, brand appeared to signifant difference according to exersice place type(in,out). The indoor sport children showed signifant score better than the outdoor sport children in the self control, sport but, the outdoor sport children showed signifant score better than the indoor sport children in the nihility, brand. 4. The lifestyle of children showed signifant difference according to exercise type. The achievement, self control, sport, brand showed signifant difference according to exercise type. The baseball and volleyball children showed signifant result better than the soccer and nonsport children in the achievement, sport. 5. The self control of the baseball children showed the positive relationship with reasioning ability. 6. The self confidence, sport, affirm, achievement, selfcontrol of the nonsport children showed the positive relationship with reasioning ability, spatial ability, remember ability, concentration power.

열변색 스마트 창호 소재로서 텅스텐이 도핑된 바나듐이산화물(WxVO₂) 나노입자와 폴리이소프로필아크릴아미드(PNIPAm)의 하이브리드 나노입자가 실리카 쉘 형성 및 PNIPAm의 표면라디칼 중합반응에 의해 합성되었다. 하이브리드 나노입자의 수분산액은 섭씨 28도의 금속-절연체 전이온도를 보유한 WxVO₂ 코어와 섭씨 32도의 하한임계 용액온도를 보유한 PNIPAm 쉘의 특성으로 인해 가시광선에서 근적외선까지의 넓은 스펙트럼 범위에서 효과적인 열변색 특성을 보였다. 하이브리드 나노입자에서 PNIPAm의 함량을 고정시키고 WxVO₂의 함량을 변화시키며 특성을 측정한 결과 섭씨 20도에서 40도의 온도 변화에서 25% 이상의 태양광 변조 변화를 구현하였으며 WxVO₂의 함량증가에 따라 입자의 증가된 뭉침현상에 의해 투과도는 85%에서 15%까지 급격하게 감소하였다. 본 연구결과는 WxVO₂효율적인 열변색 소재를 제조하기 위한 주요 기술이 될 수 있음을 보여준다. Hybrid nanoparticles based on tungsten-doped vanadium dioxide (WxVO₂) nanoparticles and poly(N-isopropylacrylamide) (PNIPAm) for thermochromic smart window applications were synthesized via silica layer formation using (3-mercaptopropyl)trimethoxysilane (MPTMS) followed by the surface-mediated free radical polymerization of PNIPAm, resulting in the aqueous dispersion of the hybrid nanoparticles. The metal-insulator transition of the WxVO₂ core at around 28 °C and the lower critical solution temperature of PNIPAm at around 32 °C enable the aqueous dispersion of the hybrid nanoparticles to present an efficient thermochromicity depending on the temperature over a broad spectral range from visible to near-infrared light. The difference in the solar modulation was over 25%, while the luminous transmittance (Tlum) significantly decreased from 85% to 15% with increasing WxVO₂ composition in the hybrids. Our results suggest that the hybridization of WxVO₂ and PNIPAm is a potential methodology for preparing efficient thermochromic materials.

일반논문 : 질적 연구에서의 현상학적 글쓰기의 전략과 방법의 탐구
정상원 ( Sang Won Jung ),김영천 ( Young Chun Kim ) 인하대학교 교육연구소 2014 교육문화연구 Vol.20 No.3
국내에서 현상학적 연구의 의미와 가치에 대한 많은 논의들이 있어 왔음에도 불구하고 현상학적 글쓰기에 대한 논의가 현저히 부족한 것이 현실이다. 따라서 이 연구는 연구 현장에서 수집한 데이터를 연구 결과로 표현하는데 필요한 글쓰기 아이디어와 방법을 규명해 보고자 한다. 우리 모두가 알고 있듯이 질적 글쓰기는 질적 연구에서도 가장 힘든 과정 중의 하나로 여겨지고 있다. 이는 이를 위해 연구자들이 참고할 만한 특별한 단계나 전략이 부재하기 때문이다. 이러한 이유로 우리는 그러한 연구자들이 글쓰기를 시작할 때 적용할 수 있는 여덟 가지의 글쓰기 방법을 규명해 보았다. 이러한 여덟 가지 전략은 구체적으로 ``주제를 찾아라.``, ``주제를 연결하여라.``, ``일화를 제시하라.``, ``성찰을 드러내어라.``, ``구체적으로 기술하라.``, ``의미를 강조하라.``, ``생생함을 살려라.``, ``독자에게 말을 거는 어조를 유지하라.`` 로 축약될 수 있다. 이러한 글쓰기 방법은 자료의 분석에서 역시 유용하게 사용될 수 있는데 그것은 글쓰기가 분석을 통한 결과물과 주제의 발견과 밀접한 관련이 있기 때문이다. Even though there has been much discussion on the meaning and value of phenomenological research in qualtiative research in Korea, there has not been much effort and research on phenomenological writing in specific. Therefore, this research contributes to the in-depth theorization of this research orientation by indentifying the concrete ideas and techniques to transform the phenomenological data collected from the field into the research result. As we all recognize, the qualitative writing is considered as one of the most difficult processes in qualitative research since there are not specific step or strategeties for the researchers to follow. For this reason, we have developed eight techniques for the qualtiative researchers to apply for when they begin to write their field data. Learning these techniques are also meaningful for data analysis because writing is closely related to the anlaytic induction and theme development.
