박주영,구할본,Park, Ju-Young,Gu, Hal-Bon 한국전기전자재료학회 2014 전기전자재료학회논문지 Vol.27 No.11

In this work, in order to manufacture the photoelectrode of dye-sensitized solar cells, the different anatase $TiO_2$ paste was prepared by simple route using hydrothermal method. In comparison with the traditional preparing process, the hydrothermally synthesized $TiO_2$ gel was used to make paste directly. Thus, the making process was simplified and the solar conversion efficiency was improved. In comparison with 5.34% solar energy efficiency of HP-1 photoelectrode, the 6.23% efficiency of HDP-1 electrode was improved by 16.67%. This is because hydrothermally synthesized $TiO_2$ gel was used to make paste directly, the dispersibility between $TiO_2$ particles was improved and get the smoother network, leading to the charge transport ability of the electron generated in dye molecular was improved. Further, HDP-2 photoelectrode delivered the best results with Voc (open circuit voltage), Jsc (short circuit current density) FF (fill factor) and ${\eta}$(solar conversion efficiency) were 0.695 V, $15.81mA\;cm^{-2}$, 61.48% and 6.80%, respectively. In comparison with 5.34% of HP-1 photoelectrode, it was improved by 27.34%.

박주영,Park, Ju-young 고려인삼학회 2021 인삼문화 Vol.3 No.-

경성제국대학의 부속기관인 생약연구소는 현재 서울대학교 약학대학 천연물 과학연구소의 전신으로, 일제강점기 인삼연구를 중점적으로 수행하였던 종합연구기관이었다. 생약연구소는 경성제국대학 의학부 약리학 제2강좌의 교수 스기하라 노리유키의 주도로 설립되게 되는데, 스기하라는 약리학 제2강좌가 설치되었던 1926년부터 고려인삼 및 한약에 관한 연구를 집중적으로 진행하였다. 약리학 제2강좌에는 의학 및 약물학 전공인 스기하라 외에도 조교수로 약학을 전공한 카쿠 텐민, 강사로 농학 및 임학을 전공한 이시도야 츠토무가 있었으며, 이들을 중심으로 1939년 생약연구소 설립 이전까지 약 36명의 연구자가 활동하였다. 이 중에서는 약 14명의 조선인 연구자들이 있었는데, 이들은 대체로 경성의전, 경성치전, 경성약전 등 전문학교 출신들로 기본적인 의약학 지식을 갖추고 한의학, 본초학 등 독자적인 의약체계를 활용하는 조선의 한약재 연구에 임하였다. 1927년부터 민병기, 김하식 등이 활동을 시작하였으며, 1930년 이후 조선인 연구자는 증가하였다. 약리학 제2강좌는 조선의 약용식물 조사 및 한약재에 대한 약리학적 작용, 성분분석 등의 분야에서 다양한 연구결과를 발표하였으며, 또한 경성의전, 경성치전, 경성마약류중독자치료소, 지방도립의원 등의 기관들과 공동연구를 진행하기도 하였다. 한편 1935년, 국내 최대의 인삼 산지인 개성에서는 "약도개성" 계획이 수립되었다. 이는 전시용 약품의 연구 및 양산화, 인삼 산업개편을 통한 수익 창출을 목적으로, 민간단체, 개성부, 관동군, 경성제국대학 등이 참여한 대규모 프로젝트였다. 1936년에 경기도립 약용식물연구소, 1938년에 경성제국대학 부속 약초원 및 병참 제약공장이 설치되었으며, 1939년, 약용식물연구소와 약초원이 결합하여 경성제국대학 부속 생약연구소가 설립되었고 스기하라는 생약연구소 소장이 되었다. 생약연구소에서는 인삼에 관한 약리학적 연구에서 더욱 나아가, 선려삼 등 인삼을 이용한 제품개발 및 판매, 그리고 인삼재배 연구가 집중적으로 진행되었다. 또한, 1941년 제주도시험장을 설립하여, 제주도산 약재를 사용한 구충제 판시를 생산하기도 하였다. 1945년 일제의 항복과 광복으로 스기하라를 포함한 일본인 연구자들은 급히 귀국하였다. 이후 생약연구소는 서울대학교에 인계되어, 경성제국대학 의학부 출신 오진섭을 소장으로 우린근, 석주명 등의 학자들이 활동하며 한국 과학계의 선도적 역할을 하였다. The Natural Products Research Institute (NPRI, 生藥硏究所), an institution affiliated with Keijo Imperial University (京城帝國大學), was the predecessor of the NPRI at Seoul National University and a comprehensive research institute that focused on ginseng research during the Japanese colonial era. It was established under the leadership of Noriyuki Sugihara (杉原德行), a professor of the second lecture in pharmacology at the College of Medicine in Keijo Imperial University. Prof. Sugihara concentrated on studying Korean ginseng and herbal medicine beginning in 1926 when the second lecture of pharmacology was established. In addition to Prof. Sugihara, who majored in medicine and pharmacology, Kaku Tenmin (加來天民), an assistant professor who majored in pharmacy; Tsutomu Ishidoya (石戶谷勉), a lecturer who majored in agriculture and forestry; and about 36 researchers actively worked in the laboratory before the establishment of the NPRI in 1939. Among these personnel, approximately 14 Korean researchers had basic medical knowledge, derived mostly from specialized schools, such as medical, dental, and pharmaceutical institutions. As part of the initiative to explore the medicinal herbs of Joseon, the number of Korean researchers increased beginning in 1930. This increase started with Min Byung-Ki (閔丙祺) and Kim Ha-sik (金夏植). The second lecture of pharmacology presented various research results in areas covering medicinal plants in Joseon as well as pharmacological actions and component analyses of herbal medicines. It also conducted joint research with variousinstitutions. Meanwhile, in Gaesong (開城), the largest ginseng-producing area in Korea, the plan for the Pharmaceutical Industry Complex was established in 1935. This was a large-scale project aimed at generating profits through research on and the mass production of drugs and the reformation of the ginseng industry under collaboration among the Gaesong Ministry, Kwandong (關東) military forces, Keijo Imperial University, and private organizations. In 1936 and 1938, the Gyeonggi Provincial Medicinal Plant Research Institute (京畿道立 藥用植物硏究所) and the Herb Garden of Keijo Imperial University (京城帝國大學 藥草園) and Pharmaceutical Factory were established, respectively. These institutions merged to become Keijo Imperial University's NPRI, which wasthen overseen by Prof. Sugihara as director. Aside from conducting pharmacological research on ginseng, the NPRI devoted efforts to the development and sale of ginseng-based drugs, such as Sunryosam (鮮麗蔘), and the cultivation of ginseng. In 1941, the Jeju Urban Test Center (濟州島試驗場) was established, and an insecticide called Pancy (パンシ) was produced using Jeju-do medicinal herbs. However, even before research results were published in earnest, Japanese researchers, including Prof. Sugihara, hurriedly returned to Japan in 1945 because of the surrender of Japanese forces and the liberation of Korea. The NPRI was handed over to Seoul National University and led by Prof. Oh Jin-Sup (吳鎭燮), a former medical student at Keijo Imperial University. Scholars such as Woo Lin-Keun (禹麟根) and Seok Joo-Myung (石宙明) worked diligently to deal with the Korean pharmaceutical industry.

This study investigated how the franchisor's supportive activities influence the franchisee's loyalty and consequently their perceived performance in the franchised restaurants. The study found that the franchisor could increase the franchisee's loyalty through supportive activities and the franchise performance in results. However, the franchisor's advertising and promotion supports did not influence the franchisee's loyalty increase, but increase the franchisee's perceived performance. In summary, supportive activities such as efficient franchise system and advisory activities could be a starting point towards high franchise performance.

박주영,권대일,남덕윤,Park, Ju-Young,Kwon, Daeil,Nam, Dukyun 한국마이크로전자및패키징학회 2016 마이크로전자 및 패키징학회지 Vol.23 No.2

전력가격의 상승으로 데이터센터의 운영비 부담이 늘어나는 가운데, 슈퍼컴퓨터에 저전력 프로세서를 사용하여 데이터센터의 전력소모를 감소시키는 연구가 활발하다. 일반적으로 모바일 기기 등의 운용환경을 기준으로 신뢰성 평가가 이루어지는 저전력 프로세서를 슈퍼컴퓨터에 사용하는 경우 상대적으로 가혹한 운용환경으로 인해 물리적, 기계적 신뢰성 문제가 발생할 수 있다. 이 논문은 슈퍼컴퓨터 운용 환경을 바탕으로 저전력 프로세서 패키지의 수명을 평가하였다. 먼저 문헌조사, 고장모드 및 치명도 분석을 통해 저전력 프로세서 패키지의 주요 고장원인으로 온도 사이클을 선정하였다. 부하-온도 관계를 확인하기 위해 단계적인 부하를 가하며 프로세서의 온도를 측정하였다. 가장 보수적인 운용조건을 가정하고 온도 사이클에 관련된 고장물리 모델을 이용한 결과 저전력 프로세서 패키지의 기대수명은 약 3년 이하로 예측되었다. 실험 결과를 바탕으로 저전력 프로세서 패키지의 기대수명을 향상하는 방법을 제시하였다. While datacenter operation cost increases with electricity price rise, many researchers study low-power processor based supercomputers to reduce power consumption of datacenters. Reliability of low-power processors for supercomputers can be of concern since the reliability of many low-power processors are assessed based on mobile use conditions. This paper assessed the reliability of low-power processor packages based on supercomputer use conditions. Temperature cycling was determined as a critical failure cause of low-power processor packages through literature surveys and failure mode, effect and criticality analysis. The package temperature was measured at multiple processor load conditions to examine the relationship between processor load and package temperature. A physics-of-failure reliability model associated with temperature cycling predicted the expected lifetime of low-power processors to be less than 3 years. Recommendations to improve the lifetime of low-power processors were presented based on the experimental results.

This study was to investigate the influence the of surface characteristics of textile materials finished with chitosan on detergency of particulate soil. The fabric was treated with glutardialdehyde as crosslinking agent to improve the fixation rate of chitosan on fabric. after chitosan finishing. The ${\zeta}$-potential of fabric was measured by streaming potential method, and the potential energy of interaction between particle and fiber were calculated by using the heterocoagulation theory for sphere-plate model. The contact angle of solution on treated fabric was decreased with increasing chitosan concentration, and well related with moisture regain. The negative ${\zeta}$-potential and the potential energy of interaction between particle and fiber of fabric treated with chitosan were decreased with increasing concentration chitosan, which was attributed to the effect of decreasing negative charge by adsorption of the cationic material. And the adsorption of anionic surfactant to fabric was increased with increasing chitosan and surfactant concentration, but the influence of ionic strength on the adsorption of anionic surfactant to fabric was biphasic with maxinum at certain ionic strength. The negative ${\zeta}$-potential was increased with decreasing adsorption of anionic surfactant to fabric.

박주영(Park, Ju Young) 기본간호학회 2017 기본간호학회지 Vol.24 No.3

Purpose: The purpose of this study was to develop a self triage application for rescue requests by disaster vulnerable populations. Literature was reviewed in order to define application trends and needs. Methods: Development of the self triage application was conducted in six stages as a hybrid model (analysis, design, development, implementation, evaluation, modification) of the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model and Driscoll & Alexander model. Application system function and contents were tried with 6 experts and 4 people with hearing impairments. Results: Expert assessment of the application for self triage showed that reliability at 5 points was the highest, followed by utility at 4.8 points. Scores for quickness and expressiveness were low at 4.6 and 4.2 points respectively. User acceptability assessment of the application was measured at 66.73 points. Conclusion: The results show that the application for self triage is helpful to disaster vulnerable populations by providing relief in disaster situations. It is expected that use of this application as a self rescue ability can be made available for disaster situations. However, it will be necessary to establish policies for communication strategies with rescuers and public relations to improve the access rate of disaster app service.
