Background: Solar urticaria (SU) is an uncommon type of photodermatoses characterized by erythematous wheal with pruritus after sunlight exposure, which shows a female predominance. Only a few studies to analyze the clinical features of SU were reported in Asia. Objectives: We aimed to analyze the clinical and photobiological characteristics of SU in Korea. Methods: We retrospectively investigated the medical records of patients with SU who visited the department of dermatology, Konkuk university medical center from January 2005 to January 2020. Results: Of a total of 44 patients, 36 (81.8%) were male and 8 (18.2%) were female. The mean age at onset was 17.6 years (range, 5-47) and the mean threshold time was 19.7 minutes. Among 32 patients who underwent phototesting, the action spectrum most commonly implicated was ultraviolet (UV) A only in 12 (37.5%), and then visible light (415nm) only was responsible for SU in 8 (25.0%). Three patients (9.4%) were induced by both UVA and visible light (415nm). Even 4 patients (12.5%) were triggered by only natural sunlight. Serum immunoglobulin E levels were measured in 33 patients, and 17 (51.5%) showed values higher than normal. The treatment most widely used were oral antihistamine (43.2%), followed by phototherapy (13.6%). Conclusion: SU is a rare photodermatosis in Korea, which shows a male preponderance. In this study, UVA and visible light (415nm) were predominant action spectrum of SU.

부흥기(Al-Nahd?ah)이후 아랍어의 양충언어현상과 현대 표준 아랍어

윤용수 한국이슬람학회 2004 한국이슬람학회논총 Vol.14 No.2

After al-Nandah since 1798, the Arab society had been experienced much rapid social revolution. This revolution had influence the linguistic consciousness among Arab. The most of. the Arab linguists in that time had suggested the proposal to the renaissance for Arabic. This dispute about Arabic renaissance had mainly concentrated into the diglossia. The insistence for the solution of diglossia was largely divided into two parts (conservative and reformist). Although they had the same object for the Arabic renaissance, the procedures for it had shown much different and confronted sharply between both. In this article, I would like to analysis each backgrounds and the difference of each insistences in order to understand the linguistics situation in the Arab world concentrating diglossia. And I will try to give the solution personally to solve the problem of diglossic situation in Arab world.

윤용수 한국아랍어아랍문학회 2001 아랍어와 아랍문학 Vol.5 No.1

Some sociolinguistic scholars divided the phenomenon of code-shifting into the interference, borrowing and code-switching according to he chosen code in the conversation. And it has been cleared that code-switching is not random alternation of two (or more) varieties both between and within sentences but to be governed not only by extra-linguistics but also linguistics factors. That is to say, it has been proved that there are some constraints of code-switching. In this articles, I will analyze the form and constraints of code-switching in Arabic language based on the educated Arabs' speech. I also will divide the code-shifting of the educated Arabs' speech into the interference, borrowing and code-switching and try to analysis each character. And I will try to find the general constraints of code-switching in the educated Arabs' speech.

All of the societies in the earth have developed their own norms to keep and regulate the conduct of personal and social relations. This norms reflect the character, value and experience of the each society. Every people in the society must observed it's own rules and norms. In islamic society, it is true that many elements of islamic norms and manners still dominate various spheres of daily life. Expecially, The Quran and Hadith have influenced absolutely the muslims' life. And it is also true that the foreign elements have had a wide and increasing influences in islamic world. Therefore we can found the coexistence of the islamic elements and the foreign one in Arab-muslim society. To understand islamic society, it is natural that we have to know the above mentioned characters and muslim's way of thinking and pattern of life. In this article, I try to introduce the characters of islamic society and it's norms and manners to understand islamic world.

윤영남,김남성,김기덕,박수진,서미자,채순용 충남대학교 농업과학연구소 2000 농업과학연구 Vol.27 No.1

External morphological characteristics of male and female of Degeeria separata, which was endoparasited in adult of the Asian ladybird, were studied by using the scanning electron microscopy(SEM). The antenna of Degeeria separata was consisted of three segment and arista. Anstae were about 750㎛ length and 30㎛ in diameter. The surface of antennae was covered with many sensilla. They were long or short, slender or thick, and straight or curved. Each three morphological types of sensilla were observed on the second and third segment of antennae. The mouthpart was sponging type. It was consisted with clypeus, labellum, labium, labrum, and maxillary palp. The labellum is 400㎛ width and double folded vertically. The leg consist of tarsus, tarsus claw, pulvilli, and empodium.

셈어의 발달과 분화에 관한 연구 : 아랍어를 중심으로 Centering around the Arabic Language

윤용수 부산외국어대학교 지중해연구소 2002 지중해지역연구 Vol.4 No.2

The Semitic language family has the longest recorded history of any linguistic group. The Akkadian language is first attested in cuneiform writing on clay tablets from ancient Mesopotamia (modern Iraq) from the mid-third millennium B.C. and Semitic languages continue to be spoken in the Middle East and in northeastern Africa today. But, lacking of the written materials and systematic research about Semitic languages, a study on the development and diversification of semitic languages is still the beginning stage in Korea. Also, Almost nothing have been carried a study on relationship of the ancient kingdoms to their languages in Arabic Peninsular. In this article, I deal the development and diversification of semitic languages centering around Arabic language. I expect that this research will be the Arabic historical linguistics in the Arabia Peninsula.

주사전자현미경을 이용한 토마토에 발생하는 아메리카잎굴파리(Liriomyza trifolii)의 외부형태적 특징

윤영남,김기덕,박수진,김남성,서미자,채순용 충남대학교 농업과학연구소 2000 농업과학연구 Vol.27 No.1

SEM을 이용하여 아메리카잎굴파리(Liriomyza trifolii)의 암 ·수컷 성충의 외부형태적 특징을 살펴보았다. 더듬이에 있어 감각모의 3가지 형태는 더듬이가는마디(funicle)에서 관찰되었으며, 모상감각기(trlchold sensillum)는 말단 부위가 뽀족한 특징적인 형태를 하고 있고 감각기들 중에서 가장 많이 분포하고 있다. 원추상 감각기(basiconic sensillum)는 길이가 13㎛, 지름이 1.4㎛에서 1.2㎛인 원형곡선형이다. 홈형 감각기(grooved sensillum)는 간상(peg) 끝에서 나온 손 모양을 하고 있으며, 이 모든 감각기들은 후각과 연관되어져 있는것으로 추정된다. 구기는 홉즙형으로 작고 펼쳐진 윗입술(labrum)과 합쳐져서 하나의 연결된 주둥이(rostrum)을 형성하고 있다. 가느다란 한 쌍의 작은턱수염(maxillary palp)은 긴 관 모양으로 각각의 세로로 이어져 있다. 발마디는 5마디로 이루어져 있으며 그 한가운데에는 패드모양의 흡착반(pulvillus)과 가시모양의 발톱사이돌기(empodium)가 있다. 아메리카잎굴파리는 흡착반과 발톱사이돌기에서 미끄러운 표면에 부착할 수 있는 물질을 분비한다. 수컷의 생식기는 매우 복잡하며 삽입구(aedeagus)는 생식기관으로서 가장 일반적인모양이다. 반면에 암컷의 생식기는 상대적으로 간단한데 이 구조는 외부로 돌출된 관모양이었다. 또한 이러한 결과를 이미 발표된 다른 여러 종의파리와 비교하였다. The external morphology of male and female of Liriomyza trifolii (Burgess) was studied using the scanning electron microscopy (SEM). Three types of sensilla were identified on the funicle of antennae. The trichoid sensilla were most conspicious and distributed with a characteristic sharp structure at the apical end. Basiconic sensilla were showed distal curvature about 13㎛ long and 1.2㎛ to 1.4㎛ in diameter. Grooved sensilla were showed a finger-like projections at the peg apex. The function of these sensilla likely to be olfactory. The mouthparts were adapted for sucking food, and formed a elongate rostrum which was incorporated with labrum. The labrum was a small and flap-like shape. The slender and paired maxillary palp seemed to combine with each other lengthwise to long tube. The tarsus typically consisted of 5 segments, which might be variously modified, principally by thickening or flattening. The segment healed a pair of claws. Beneath the claws, there was a pair of pad-like pulvillia and a bristle-like median empodium. L. trifolii secreted on the pulvillus and empodium an adhesive substance that enable them to cling to smooth surfaces. Male terminalia was complicated. The name 'aedeagus' seemed the best available general term for the copulatory organ, otherwise, female terminalia was usually relatively simple. This structure was reduced and formed a telescopic, eversible, and tubular ovipositor.

피로하중, 산성비, 염해 및 동결융해 등 각종 원인에 의해 시멘트 콘크리트 구조물의 성능 저하가 건설산업분야의 문제점으로 대두되고 있다. 일반적으로 성능이 저하된 시멘트 콘크리트 구조물의 보수재로는 폴리머 복합재료가 널리 사용되고 있다. 보통 시멘트 콘크리트에 폴리머를 첨가하면, 작업성의 경우 폴리머의 혼입량이 증가 할수록 작업성이 증가하고 이에 따라 공기량이 증가하는 경향을 나타내었다. 또한 압축강도는 폴리머 시멘트비가 10%에서 가장 높은 값을 보였으며, 휨강도의 경우는 폴리머 시멘트비가 증가할수록 강도가 증가하는 경향을 나타내었다. 또한 폴리머 시멘트 모르타르의 직접인장접착강도에서는 폴리머-시멘트비 10%, 소포제 1%에서 가장 높은 접착강도가 나타났으며, 내후성 시럼 후의 직접인장접착강도 실험에서는 보두 수께 5mm가 가장 높은 접착강도를 나타내었다. 이상과 같은 실험 결과를 볼 때 보수재로 사용되는 폴리머 시멘트 모르타르의 경우는 폴리머 시멘트비 10%, 소포제1%의 배합으로 약 5mm의 두께로 보수를 하는 것이 가장 유리함을 알 수 있었다. This research was conducted to experimentally evaluate the characteristics of the tensile adhesion strength of polymer cement mortar for repair of cement concrete structures. Air content of polymer cement mortar was improved with increment of polymer cement ratio. Water absorption of polymer cement mortar was decreased with increment of polymer cement ratio. Compressive strength of polymer cement ratio 10% was higher than those of others. Flexural strength of polymer cement mortar was improved with increment of polymer cement ration. The tensile adhesion strength of polymer cement ration 10% and antiformer agent content 1% was higher than those of others. After weathering test, the tensile adhesion strength of thickness 5mm was found to be higher than those of others.

불포화 에스터 수지의 큰 이용분야의 하나로 건축재료가 있으나 여기서 가장 문제로 되어 있는 것이 바로 열적 특성의 개선이다. 따라서 본 연구에서는 외부온도가 폴리머 콘크리트의 강도특성에 미치는 영향을 검토하기 위하여 외부온도 20∼120℃ 범위로 하여 폴리머 콘크리트의 물리·역학적 특성을 구명하는데 목적이 있다. 본 연구에서는 불포화 폴리에스터 수지를 결합재로 하고 탄산칼슘을 충진재로, 규사를 잔골재로 치환하고, 굵은골재를 쇄석으로하는 폴리머 콘크리트를 제조하여 외부온도에 따른 강도특성을 검토한 바, 폴리머 콘크리트의 사용 적정온도는 50℃이내가 적당할 것으로 판단되며, 50℃이상에서 사용할 경우는 난연성이 우수한 탄소섬유를 사용해야 할 것이다. In this study, the polymer concrete was made to investigate its strength properties, in which unsaturated polyester resin was used as s binder, calcium carbonate as the filler and silica sand as th fine aggregate, and crushed stone as the coarse aggregate. The effects according to the external temperature on strength properties of polymer concrete were examined. Test result showed that the compressive, flexural and tensile strengths of the polymer concretes decreased with increasing external temperature. The elasticity of modulus of the polymer concretes decreased with increasing external temperature.
