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.

Su‑Jin Lee,김성일,Pil‑Wan Han,김창업 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4

This paper deals with the characteristics analysis of 3-phase induction motors for electric power steering applications by combining fnite element analysis with an equivalent circuit model. Induction motors for automobiles have high magnetic saturation due to size limitations. Accordingly, to improve the accuracy of the equivalent circuit analysis, it is necessary to consider the magnetizing reactance according to the magnetizing current. An equivalent circuit analysis method that takes into account the magnetic saturation of 3-phase induction motors is proposed and verifed through a test.

Analysis of Sap Production and Composition of Acer okamotoanum from Artificial Stands in Different Tapping Time in Jin-ju Region in Korea(진주지역 인공식재 우산고로쇠의 수액 채취 시기별 출수량 및 성분 분석)

Jin-SungHUH,Jeong-WoonKIM,Jun-HyuckYOON,Su-YeonLEE 한국목재공학회 2020 목재공학 Vol.48 No.2

This study was conducted to analyze the sap flow and composition by tapping date in Acer akamotoanum from an artificial forest in the City of Jinju. The sap was collected from five saplings (diameter at breast height10-20 cm) in two phases with an interval of a month. During phase 1 (January 10, 2019 - February 9, 2019) with daily mean temperature of 1.16±2.15℃, 60.59 liters of sap was collected over 32 days. Phase 2 (February 12, 2019 - February 22, 2019) with daily mean temperature of 2.55±1.30℃ yielded 13.38 liters of sap over 11 days, which was a reduction to 22% of the total sap flow in phase 1. The analysis of sugar composition in the collected sap from phase 1 and 2 showed that sucrose concentration was 2.5% at its highest during the earlier days of collection and decreased to 0.8% at the end. Glucose and fructose concentrations were measured near 0, and were lower than sucrose concentration. The most prominent inorganic elements in the collected sap were potassium (41.69 - 89.75 mg/kg), calcium (24.66 - 48.14 mg/kg) and magnesium (10.18 - 27.25 mg/kg). The contents of sucrose and inorganic components between the samples collected from phase 1 and 2 did not show significant differences. The sap flow amounts of A. okamotoanum from different tapping periods showed a notable variation, but there were no significant differences in the contents of sugar or inorganic elements. 본 연구는 진주시 소재 우산고로쇠 인공림에서의 수액 채취 시기별 출수량 및 구성성분을 분석하기 위해 수행되었다. 수액채취는 한 달 간격으로 2회에 걸쳐 이루어졌으며, 각 회당 채취목은 각각 소경목(흉고직경 10~20 cm) 5본씩 이었다. 일평균 기온이 1.16 ± 2.15℃로 조사된 1차 시기(2019년 1월 10일 ~ 2월 09일)의 수액 총 출수일이 약 32일, 총 출수량은 약 60.59 L로 관찰되었다. 일평균 기온이 2.55 ± 1.30℃로 조사된 2차 시기(2019년 2월 12 ~ 22일)에는 총 출수일이 약 11일이었으며 총 출수량은 약 13.38 L로 1차 시기 기준의 약 22%에 해당하는 양으로 감소하였다. 1, 2차 채취 시기별 수액의 당 성분분석 결과 자당(Sucrose)의 함량이 출수초기 최고 2.5%를 나타냈으며 출수 종료시점에는 최소 0.8% 대로 감소하였다. 포도당(Glucose)과 과당(Fructose)은 Sucrose에 비하여 함량이 낮았으며, 0에 가까운 수치를 나타내었다. 채취 수액의 무기성분 분석결과, 주요 성분은 칼륨(41.69 ~ 89.75 mg/kg), 칼슘(24.66 ~ 48.14 mg/kg), 마그네슘(10.18 ~ 27.25 mg/kg)이었다. 1, 2차 채취 시기별 수액 간의 sucrose함량 및 무기성분의 함량 범위는 유의적인 차이를 보이지는 않았다. 결과적으로 시기를 달리한 우산고로쇠 수액 채취에 있어서 출수량은 큰 차이를 보였지만 당 및 무기성분 함량의 경우에는 유의적 차이가 나타나지는 않았다.

Cyclic Loading Test of Structural Walls with Small Openings

Hyun-Jin Yu,Su-Min Kang,Hong-Gun Park,정란 한국콘크리트학회 2019 International Journal of Concrete Structures and M Vol.13 No.6

This study aimed to investigate the effects of small openings on the structural performance of reinforced-concrete(RC) structural walls. Cyclic lateral loading tests were conducted on five RC walls with an aspect ratio of 2.6 and small openings. The main test parameter was the size of the small openings. The specimens were designed to fail after flexural yielding, considering the typical failure mode of slender RC walls. The structural performances of the test specimens were analyzed based on the test results in terms of the load-carrying capacity (flexural strength), hysteretic behavior, strain distribution, and the size of the openings. The specimens showed flexural yielding regardless of the size of the openings, and the flexural strength and deformation capacity were not significantly affected by the small openings. This result indicates that small openings do not affect the flexural behavior of slender walls if the walls have sufficient shear resistance and the small openings are located away from the extreme compressive end and in the compression zone where compressive stress does not decrease.

It is also known that glaring discrepancy in some events as compared with world`s records tends to be better having potentially superior events, and the mumber of medals received by Korean female for the promotion of the national prestige has been improved,

SiO₂ nanodot arrays using functionalized block copolymer templates and selective silylation

Kim, Su Min,Ku, Se Jin,Kim, Jin-Baek IOP Pub 2010 Nanotechnology Vol.21 No.23

<P>Silicon oxide nanodot arrays were fabricated using functionalized block copolymer templates and selective silylation. A polystyrene-<I>b</I>-poly(acrylic acid/acrylic anhydride) (PS-<I>b</I>-PAA/AN) thin film containing spherical nanodomains was used as a template to build nanoscopic silica structures. A PS-<I>b</I>-PAA/AN thin film was prepared by acid-catalyzed thermal deprotection of polystyrene-<I>b</I>-poly(<I>tert</I>-butyl acrylate) on an SU-8 resist film containing a photoacid generator. This resulting film has excellent solvent and thermal resistance due to crosslinked anhydride linkages in carboxyl-functionalized PAA/AN block domains. Silicon was introduced by spin-spraying of hexamethyldisilazane (HMDS) over the entire surface of a self-assembled PS-<I>b</I>-PAA/AN thin film. HMDS was selectively reacted with carboxylic acid groups in spherical domains of a PAA/AN block. SiO<SUB>2</SUB> nanodot arrays were generated by oxygen reactive ion etching. </P>

현대독일영화의 한 경향: 포스트모던 시대의 역사영화 -오스카 뢸러의 < 유대인 쥐스-양심 없는 영화 >(2010)를 중심으로

조수진 ( Su Jin Cho ) 한국독어독문학회 2016 獨逸文學 Vol.57 No.2

Der Film Jud Suß - Film ohne Gewissen von Oskar Roehler thematisiert die Geschichte Ferdinand Marians, der im dritten Reich die Hauptrolle des Propagandafilms Jud Suß von Veit Harlan gespielt hat. Der Film zeigt einige postmoderne asthetische Strategien, namlich eine Fiktionalisierung der historischen Fakten, oder vielschichtige Narrativstrukturen, unter anderem auf der Basis der Hommage, und Selbstreferenzialitat. Zunachst sind die Figuren dieses Films historische Menschen, doch ihre Charakterzuge und die sozialen Verhaltnisse, in denen sie agieren, werden durch Roehlers Einbildungskraft rekonstruiert und neu erschaffen, um sie als Mittel, ein Sittenbild der Nazizeit zu prasentieren, einzusetzen. Der Film beinhaltet die Spiegelstruktur, den Film im Film und das Drama im Drama. Das Publikum hat dabei die Moglichkeit, Identifizierung und Verfremdungseffekte abwechselnd zu erleben. Die postmoderne Asthetik des Films Jud Suß - Film ohne Gewissen tragt einerseits dazu bei, die Naziideologie zu karikieren und zu entlarven. Doch andererseits verhindert sie, dass man die historischen Fragen erkennt, und der Film bußt so an Historizitat ein.
