In this paper, we study a method of designing a reflector for LED light sources with an asymmetric light distribution. In a sports game, lighting with a symmetric distribution makes the athlete and spectators look directly at the light source, so it can cause glare. We derive the optimal tilt angle and design a reflector with asymmetric light distribution to solve these problems. Afterward, performance is analyzed according to the tennis-court lighting standard, and is confirmed to meet the class 1 European standard.

Currently, the world is attracted by a cross-cultural due to globalization and various cultural exchanges. In this era, universities need to systematically deploy their symbol marks by applying the concept of cultural exchange. The study compared the symbol marks of the top 50 British university rankings published by The Times in 2019 and the top 50 American university rankings published by U.S. News in 2019 with the symbol marks of the top 100 universities surveyed by the Chinese Academy of Sciences in 2019. The study analyzed the historical origins and development of the culture design by comparing the symbol marks of Chinese, English, and American universities in terms of shape, component, and color. As a result of the research, the Chinese UI has gone through the stage of imitating the symbol marks of British and American universities then developed and improved by combining Chinese national culture. Based on these analyses, future direction and improvements of across-cultural are as follows. Firstly, universities need to create symbol marks by using their different cultural characteristics. Secondly, we need a fusion of different cultures and Chinese universities' unique ideas and characteristics. Based on these results of the study, we intend to present the possibility of in-depth research by focusing on the conceptual aspects. 현재 세계는 글로벌화와 다양한 문화교류로 인해 크로스 컬처 현상이 내/외적으로 일어나고 있으며 국가 홍보차원에서도 매우 중요한 역할을 하고 있다. 이러한 시대에 대학은 특성화 된 교육문화 형성에 깊이 관여되어 있는 만큼 차별화 된 자신들의 브랜드 이미지를 체계적으로 구축할 필요성이 있다. 본 논문은 2019년 중국대학평가에서 발표한 중국 종합 대학 순위 100위까지 학교의 심벌마크와 2019년 타임지가 발표한 영국 종합 대학 순위 50위, 2019년 미국 U.S.News가 발표한 미국 종합 대학 순위 50위까지 총 100개의 서양대학을 연구의 범위로 설정하여 동서양의 UI디자인을 문화 교류적 측면에서 비교 연구하였다. 연구의 시발점으로 해석적 방법론 측면인 중국과 서양(영국·미국) 대학의 심벌마크를 형태, 구성요소, 색상으로 나눠 비교한 후, 크로스 컬처럴 디자인 관점의 역사적 근원과 조형적 발전 형태의 연구를 목적으로 한다. 연구의 결론으로는 중국 대학의 심벌마크는 서양(영국·미국)대학 심벌마크의 모방을 거치면서 중국의 민족 문화 특색과 결합하여 발전, 보완하는 단계를 거치고 있다. 이러한 분석결과를 바탕으로 크로스 컬처럴 디자인적 관점에서 향후 방향성과 개선점은 다음과 같다. 첫째, 학교별 문화 특색을 반영한 구성요소로 다원화된 심벌마크를 만들어야 하며 둘째, 서로 다른 문화의 융합과 중국 대학만의 이념 및 특징을 표현할 수 있는 디자인적 융합이 필요함을 알 수 있었다. 이러한 연구 결과를 바탕으로 차후 내면적 요소의 분석과 컨셉 도출의 중요성에 대한 심도 있는 연구의 가능성을 제시하고자 한다.

The Interaction of Quantifier Scope in the Agree system: Going back to QR?

서진희 사단법인 한국언어학회 2002 언어학 Vol.0 No.34

Hornstein (1995, 1999) has shown that Quantifier Raising (QR) as a rule of Universal Grammar can be eliminated. He argues that it is supported not only by the theory-internal reasons in the Minimalist Program (MP), but also by empirical motivations. His system which exploits Case chain structure or other A-chains crucially relies on movement with copying and deletion whether it is feature movement (Attract) or phrasal movement. The recent version of MP, however, suggests that we dispense with Attract, together with complications it produces and Checking reduces to deletion under matching (Agree) with a local goal activated by the uninterpretable feature without movement. The purpose of this paper is, therefore, to show that non-QR approach to the relative scope of quantifiers still works in the new system of MP. It is argued that the EPP effect by the functional category (T and v in particular) is responsible for the explanation rather than Case driven A-movement. Some apparent problems presented for the support of the existence of QR are also discussed and it is shown that there is no empirical loss regarding them.

The principal objective of this experiment was to evaluate the anti-atherosclerotic activity of hempseed water extract in apolipoprotein E knockout (ApoE KO)mice. Fourteen male ApoE KO mice were divided into 2groups and were treated via intragastric inoculation for 14weeks. The hempseed water extract (HWE) inoculation group exhibited greater gains in weight as compared to the control group, which was inoculated with distilled water. Plaque lesion areas in the aortic sinus were reduced in the HWE group. Total plasma cholesterol, LDL-cholesterol,atherosclerotic index, and cardiac risk factor were all reduced in the HWE group. These results demonstrate that HWE is an excellent nutritional resource and evidences anti-atherosclerotic activity in ApoE KO mice. Further studies will be required to assess the pharmacological mechanisms underlying these effects.

This paper aims at showing firstly, that the parameterized Universal Grammar is also accessible in second language acquisition based on the data found in the English Agreement acquisition by Korean speakers and secondly, that the theoretical claim that the acquisition of Agreement is related to the Subject Drop phenomenon can be supported by the second language acquisition data. The functional category AGRP which is crucial here can be parameterized according to its features with Korean of -Agr and English of +Agr. Two groups of 40 each were tested and the result shows that the parameter resetting is possible in terms of the Agreement feature. In addition to Agreement test, three more tests for the distribution of Subject Drop, Subject Raising and NPI(Negative Polarity Items) were conducted in order to find the correlation among those grammatical phenomena. The result is that the acquisition of Agreement and the Subject Drop possibility are correlated but that they are not related to the obligatory Subject Raising process. Finally, NPI distribution test which is supposedly related to the Subject Raising turned out to carry little information since the average grades from both groups were very low.

주어-조동사 도치에 관한 소고

서진희 한국영어어문교육학회 2000 영어어문교육 Vol.6 No.-

It has been one of the puzzles in the English syntax that so called the rule of subject-auxiliary inversion (SAI) is not allowed in subject wh-movement while it is not obligatory in non-subject wh-movement in a root sentence. This asymmetry has been a puzzle since SAI itself was thought to be a part of question construction as we can observe from yes/no questions. The asymmetry gets more complicated in terms of sentence embedding. i.e no SAI is permitted in the embedded context in question. The goal of this paper is to suggest an unified analysis for this unsolved grammatical phenomena on the basis of Rizzi (1997)'s recent work. The main idea is that SAI is not a I-to-C movement but one of I-to Focus where Focus is a functional category and its phrase is located between CP and IP. The other proposal is that Wh-movement is no more hornogeneous in terms of landing site between a root and an embedded sentence: the target for a wh-phrase in the former is the Spec of FocP (Focus Phrase) but the one in the latter is the Spec of CP as the standard theory assumes. Pesetsky (1999)'s analysis is discussed and its theoretical and empirical shortages are pointed out. Its rather radical proposals such as the one that the nominative case is just an uninterpretable tense feature of DP and the other that ‘that’ is no longer a complementizer but an element of I(nflection) make it less acceptable in spite of the possibility that it can get rid of Case theory entirely, which would be ideal in the spirit of minimalism.

The purpose of this study is to derive the priority order of introducing smart construction technologies which simultaneously minimizes all of the economic, psychological, and communicating costs with maximizing utilities of the smart construction technologies. As for smart construction technologies, this study classified eight technology types - BIM, virtual reality and augmented reality, drone, robot and automation, 3D printing, internet of things(IoT), big data and artificial intelligence(AI) technology, sensor. In addition, each of the eight technologies has two functional options. This study used the House of Quality model to derive the priority order of introducing smart construction technologies. The completed House of Quality shows the following results. Checking the real-time work progress by video shooting through drone technology was ranked as the highest priority among the 16 smart construction technology functional options. On the other hand, the functional option that took the lowest priority was constructing a building quickly(rapid construction) at the construction site through 3D printing technology. 본 연구의 목적은 기술 도입비용을 최소화하는 한편, 업무 관련 효용을 최대화하는 스마트 건설기술 기능옵션들의 도입 우선순위를 도출하는 것이다. 본 연구는 스마트 건설기술 기능옵션으로 총 16가지를 제시하였다. 구체적으로 8가지 스마트 건설기술들(BIM 기술, 가상(VR)·증강(AR)현실 기술, 드론 기술, 로봇·자동화 기술, 3D 프린팅 기술, 사물 인터넷(IoT) 기술, 빅데이터·인공지능 기술, 센서 기술)을 분류하고 각각의 기술별로 2가지 기능옵션들을 선별하였다. 품질의 집 모형을 이용하고, 건설시공업체 대상 설문조사와 전문가 대상 설문조사를 통하여 스마트 건설기술 기능옵션들의 효용과 도입비용들을 계산하여 최종적으로 각 기능옵션들의 상대적 가치와 도입 우선순위를 도출하였다. 스마트 건설기술 기능옵션들 중 가장 높은 우선순위를 차지한 것은 드론 기술을 이용하여 영상촬영으로 실시간 작업진행을 확인하는 기능으로 나타났다. 반면에, 최하위의 도입 우선순위를 차지한 기능옵션은 3D 프린팅 기술을 통해 건설현장에서 신속한 건축물 시공(쾌속시공)을 하는 것으로 나타났다.

Quantitative Analysis of the Facial Nerve Using Contrast-Enhanced Three Dimensional FLAIR-VISTA Imaging in Pediatric Bell’s Palsy

서진희,유선경,이인호,이정은,이소미,조현해 대한자기공명의과학회 2015 Investigative Magnetic Resonance Imaging Vol.19 No.3

Purpose: To evaluate the usefulness of quantitative analysis of the facial nerve usingcontrast-enhanced three-dimensional (CE 3D) fluid-attenuated inversion recoveryvolumeisotopic turbo spin echo acquisition (FLAIR-VISTA) for the diagnosis of Bell’spalsy in pediatric patients. Materials and Methods: Twelve patients (24 nerves) with unilateral acute facialnerve palsy underwent MRI from March 2014 through March 2015. The unaffectedsides were included as a control group. First, for quantitative analysis, the signalintensity (SI) and relative SI (RSI) for canalicular, labyrinthine, geniculate ganglion,tympanic, and mastoid segments of the facial nerve on CE 3D FLAIR images weremeasured using regions of interest (ROI). Second, CE 3D FLAIR and CE T1-SE imageswere analyzed to compare their diagnostic performance by visual assessment (VA). The sensitivity, specificity, and accuracy of RSI measurement and VA were compared. Results: The absolute SI of canalicular and mastoid segments and the sum of the fivemean SI (total SI) were higher in the palsy group than in the control group, but withno significant differences. The RSI of the canalicular segment and the total SI weresignificantly correlated with the symptomatic side (P = 0.028 and 0.015). In 11/12(91.6%) patients, the RSI of total SI resulted in accurate detection of the affectedside. The sensitivity, specificity, and accuracy for detecting Bell’s palsy were higherwith RSI measurement than with VA of CE 3D FLAIR images, while those with VA ofCE T1-SE images were higher than those with VA of CE 3D FLAIR images. Conclusion: Quantitative analysis of the facial nerve using CE 3D FLAIR imaging canbe useful for increasing the diagnostic performance in children with Bell’s palsy whendifficult to diagnose using VA alone. With regard to VA, the diagnostic performanceof CE T1-SE imaging is superior to that of CE 3D FLAIR imaging in children. Furtherstudies including larger populations are necessary.
