유효라,정지수 경찰대학 경찰대학 2024 경찰학연구 Vol.24 No.1

본 연구는 치안분야 R&D과제에 대해 DEA 기반 효율성을 분석하고 그룹간 효율성을 비교하여 개선점을 찾아보는데 의의가 있다. 이를 위해 2015년부터 2021년까지 진행된 경찰청과 행안부 사업 중 치안 활동과 연관된 11개 사업의 111개 과제를 분석대상으로 하였다. 과제별 투입지표로는 투입예산과 참여인력, 산출지표로는 창출된 국내외 특허, SCI(E) 논문수를 활용하였다. 그리고 치안 목적(과학수사, 교통안전, 대테러·경비, 범죄예방·순찰·수색, 신고·현장지원), 연구개발단계(기초단계, 응용단계, 개발단계), 연구수행주체(국공립연구소, 출연연구소, 대학, 중소기업, 기타), 세부사업(사업1~사업11) 4개의 그룹 간의 효율성의 차이를 비교하기 위하여 후속 분석으로 Kruskal-Wallis 검정과 Mann-Whitney U 검정을 실시하고, 분석결과에 따라 시사점을 도출하였다. This study is meaningful in that it conducts DEA-based efficiency analysis for R&D projects in the field of public safety and finds points of improvement through comparison between different R&D projects. Among the projects carried out by the National Police Agency and the Ministry of Public Administration and Security from 2015 to 2021, 11 programs and 111 projects that were closely related to the police field were analyzed. As input indicators for each specific project, the input budget and number of participants were used, and domestic and foreign granted patents and the number of SCI(E) papers were used as output indicators. To compare the efficiency differences among 4 groups based on ①the purpose of policing R&D (scientific investigation, traffic safety, counterterrorism and surveillance, crime prevention·patrol·search, 112 reporting and on-site support), ②the R&D stages(basic stage, applied stage, development stage), ③the executing entities of the research (public research institute, government-funded S&T research institutes, university, SMEs, others), and ④ detailed projects (Project 1 to Project 11), subsequent analyses were conducted using Kruskal-Wallis and Mann-Whitney U tests. Subsequently, implications were derived based on the analysis results.

Combing the cited Buddhist scriptures, this article discusses the variants from the perspective of linguistics, in order to restore the original appearance of the book.

從敦煌原卷字詞看《敦煌歌辭總編》的誤校

劉曉興(유효흥) 한국교통대학교 동아시아연구소 2020 동아문헌연구 Vol.- No.-

As one of the important parts of Dunhuang folk literature, the literary research value of Dunhuang songs is big. Since most of them are handwritten documents, mostly folk works, and more popular characters, the philological and linguistic research value of Dunhuang Songs is also great. Therefore, a large number of scholars have sorted and edited the songs, and Mr. Ren Zhongmin’s “Dunhuang Geci Zongbian” is one of them. However, due to the fact that the clear Dunhuang materials at that time had not yet been published, there are still many different contents in the “Dunhuang Geci Zongbian”. In view of this, after checking the photocopy materials and color drawing materials of the clear Dunhuang original volume, we reorganized the Dunhuang songs and wrote a number of opinions to discuss the “Dunhuang Geci Zongbian”. Some of the content is a discussion of the text, and some is a discussion of the collation records. Judging from the research situation, the characters and words used in the Dunhuang original volume are mostly in line with the original meaning of the song. There is no need to change the text of the original volume because of new solutions.

초보자의 전자회로 프로토타이핑을 위한 회로제작방식 제안

유효라,박승호 디자인융복합학회(구.한국인포디자인학회) 2015 디자인융복합연구 Vol.14 No.5

In the era of installation art, service design and product design, the interaction with users is more important than ever. So the designers and artists have to know the technological implementation including electronic and computer engineering. Also due to the development of system helps a collaborative work, D.I.Y. movement is invigorated, which affects people who want to make a working prototype with electronic circuit by themselves. Therefore many kinds of education course have been increased, like physical computing, but still tools are not easy to use for the beginners. Therefore, the goal of this research is to propose a new type of a bread board kit named NUDDY BOARD which is easier for the beginners. To do that, I studied the process and features of making electronic circuit. And I compared prototyping tools for the general users and for the beginners based on previous research. There were several problems to solve. So I designed NUDDY BOARD which has transparent body, easy wiring system and separable physical structure. With this concepts, it is easy to understand and make a physical electronic circuit system and also easy to store or restore them. After all, it can be helpful for novices to make a working prototype by themselves. 최근 예술 설치물과 서비스디자인, 제품 디자인에서 사용자들과의 상호작용이 증가하며 이를 설계하는 디자이너와 예술가의 역할이 기술적 구현의 범위까지 확대되었다. 더불어 협업 플랫폼의 발달로 전자공작 및 제품의 D.I.Y운동이 확산되면서 전자회로 프로토타이핑에 대한 비전공자의 접근들이 증가하고 있다. 이에 따라 피지컬 컴퓨팅 등과 같이 초보자와 비전공자를 위한 교육과정들이 증가하고 있지만 이에 활용되는 도구들은 여전히 그 한계를 지니고 있다. 따라서 본 연구에서는 초보자의 전자회로제작과정의 특징 선행연구들을 중심으로 일반적 회로제작 방식과 도구, 초보자를 위한 대안적 회로제작 방식과 도구를 비교 분석한다. 이를 통해 나타난 문제점들을 해결하기 위해 보조적 회로제작도구 및 방식을 제안하고 사례를 들어 적용하고자 하였다. 최종적으로 제안된 NUDDY BOARD는 투명성, 배선의 단순화, 분리의 3가지 디자인으로 회로도 전체구성을 쉽게 파악하고, 배선을 간소화하며, 도면보관의 보관 및 복구가 용이함의 장점을 가진다. 따라서 이는 초보자가 기존도구를 활용할 때 갖는 어려움을 극복하고 더욱 쉽게 전자회로 프로토타이핑에 접할 수 있도록 돕는다.

유효정,김지영,조수진,김영주,박혜숙,하은희,박은애 대한소아청소년과학회 2008 Clinical and Experimental Pediatrics (CEP) Vol.51 No.7

Purpose:Abnormal activation patterns of Th1/Th2-cells have been suggested to increase the prevalence of allergic diseases. Prevention is regarded as an important corner stone in the management of allergic diseases. In this study, we have investigated the relationship between cord blood levels of IL-4, IL-10, and IL-12 in preterm newborns and the development of allergic respiratory diseases in infancy Methods:Forty-six preterm newborns born at the Ewha Womans University Mokdong Hospital between January 2003 and July 2005, were enrolled for this study, and consent was obtained to test their cord blood samples. Clinical history was obtained from the hospital records. Cord blood was obtained at birth and kept frozen until it was tested. The levels of IL-4, IL-10, and IL-12 were determined by enzyme-linked immunosorbent assay (ELISA). Results:All infants were followed-up for a median of 16.0 months±13.2 d (range, 12.0 to 36.0 months). Eighteen infants who developed wheezing showed lower cord blood levels of IL-12 (366.60±140.40 vs 435.09±91.20 pg/mL, P=0.009). Cord blood levels of IL-4 and IL-10 showed no significant difference between the two groups. Four newborns who later developed asthma, and infants with asthma showed lower IL-12 level in the cord blood than other groups. Conclusion:Lower concentration of cord blood levels of IL-12 in newborns who later developed wheezing and asthma suggested that they had abnormal activation patterns of Th1/Th2-cells at the time of birth, and cord blood IL-12 level can be used as a predictor of allergic respiratory diseases.

재한 중국인 사무직 근로자의 직무특성, 조직 특성, 문화차이가 조직 동일시에 미치는 영향 연구

유효초,조예희,최순권 한국전문경영인학회 2018 專門經營人硏究 Vol.21 No.4

본 연구에서는 한국기업에서 일하고 있는 중국인 사무직 근로자들의 직무특성, 조직특성, 문화차이 요인이 조직 동일시에 영향을 미치는 영향을 실증분석을 통해 살펴보았다. 이를위해 한국에 소재한 기업에서 일하고 있는 중국인 사무직 근로자 152명에게 설문조사하여다중회귀 분석을 진행하였다. 실증연구 분석결과, 첫째, 재한 중국인 사무직 근로자들의조직 동일시에 가장 큰 영향을 미치는 요인은 동료와의 관계로 나타났다. 이는 본 연구설문조사 대상인 재한 중국인 사무직 근로자들이 한국인 동료와 좋은 관계를 형성하는것이 조직 동일시를 높이게 하는데 핵심 결정 요인이라고 추론된다. 둘째, 재한 중국인사무직 근로자의 직무특성요인 변수인 직무중요성과 조직특성요인 변수인 승진가능성은조직 동일시에 정(+)의 영향을 미치는 것은 입증되었다. 이는 재한 중국인 사무직 근로자들은 자신의 직무가 의미 있고 중요한지를 예민하게 느끼는 것을 확인한 것이다. 즉 재한중국인 사무직 근로자가 자신의 직무에 대한 직무중요성을 높게 인식할수록 조직 동일시가 높게 된다는 것을 알 수 있다. 또한 이런 근로자들이 대부분 고학력이며 젊어서 승진할기회를 중요하게 생각하는 것으로 판단된다.
