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.

Objectives : It is known that the five Su points are very useful clinically. The following study was undertaken in order to find out the general characteristic and the origin of the five Su points. Methods: We investigated the relation of symptoms that are treated by five Su points and Shi-Dong Suo-Sheng-Bing(是動 所生病). The main reference book was Zhen Jiu Jia Yi jing(鍼灸甲乙經) and the author took Liver Meridian of Foot Gworeum(足厥陰肝經) as an example. Results : 1. Five Su point of Liver Meridian of Foot Gworeum(足厥陰肝經) treats Shi-Dong-Bing(是動病) of Liver Meridian of Foot Gworeum. It is peculiarity of Five Su point of Liver Meridian of Foot Gworeum, differed from the others acupoints. Symptoms of Shi-Dang-Bing appears with the abnormal pulsation of Merdian Gi(脈氣), and the special feature of Shi-Dang-Bing is the symptoms are consisted of disorders of whole body, trobles of an internal organ, and psychosomatic disorders. 2. In <Su Wen San Bu Jiu Hou Lun (素問 三部九候論)>, it is described the part of pulse feeling for Shi-Dong-Bing(是動病) of Liver Meridian of Foot Gworeum(足厥陰肝經) as ‘A region that is 2 Chon(寸) from the basic digital joint of the first toe’. This region is agree with the acupoint of Liver Meridian of Foot Gworeum in <Mai-Jing(脈經)>, <Qian-Jin-Yao-Fang(千金要方)>. And Haeng-gan(行間) Tae-chung(太衝), members of five Su-points of Liver Meridian of Foot Gworeum is situated the same region. So we suppose that the part of pulse feeling for Shi-Dong-Bing of Liver Meridian of Foot Gworeum is transformed into Haeng-gan(行間) Tae-chung(太衝), among the five Su points.

Magnetization Analysis for Outer Rotor Brushless DC Motors Using Polar Anisotropic Ferrite Ring Magnets

Sung‑Il Kim,Su‑Jin Lee,Jeong‑Jong Lee,Chang‑Eob Kim 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.3

Ferrite-bonded magnets have been extensively used in small brushless DC (BLDC) motors for low torque applications such as fans and pumps. In particular, some motors of them with ferrite-bonded magnets, frequently called as plastic magnets, do not have a rotor core in order to reduce manufacturing costs and inertia of the rotating part. Accordingly, the magnetization distribution of the bonded magnets has a polar anisotropic direction to secure more magnetic fux. As a result, the magnetization orientation of the magnets is highly signifcant to accurately predict the performances of the BLDC motors. This paper deals with the magnetization analysis of the polar anisotropic ferrite ring magnet applied to an outer rotor type BLDC motor. The motor is employed for an electric water pump, and its rotor including the impeller consists of only the ferrite-bonded magnet material and made by injection molding. Consequently, a magnetizing fxture and an impulse magnetizer are not used for the magnetization of the outer rotor type motor. Instead, samarium–cobalt (SmCo) magnets having a relatively high curie temperature are applied for generating magnetic feld. Finally, this paper presents a process to determine the anisotropic orientations of a ferrite ring magnet by fnite element method. In addition, the validity of the analysis method is verifed by test results

청소년 시의 새로움과 가능성

이성수(Lee Sung su) 우리말교육현장학회 2017 우리말교육현장연구 Vol.11 No.2

2000년대 들어 문학계에서 주목할 만한 현상 중 하나로 청소년 문학의 활성화를 거론할 수 있다. 특히 청소년 소설은 양적으로나 질적으로 나 매우 비약적인 성장을 했다. 그러나 청소년 시는 상대적으로 빈약한 상태에 머물러 있었다. 이러한 상태는 2010년 박성우 시인의 청소년 시집 『난 빨강』의 출간으로 변화기를 맞는다. 그리고 2015년부터 2017년까지 2년간 창비출판사의 청소년 시선(詩選) 시리즈가 10권으로 출간되었다. 이러한 청소년 시집의 출간을 맞이하여, 청소년 시가 과연 앞으로 어떤 양상으로 전개될 것인지 청소년 시의 새로움과 가능성을 검토해 볼 필요가 있다. 이 글은 박성우 시인의 청소년 시집 2권과 창비 청소년문학 시선(詩選) 10권을 대상으로 삼아 그 성과와 가능성을 짚어보았다. 청소년 시는 그동안 존재를 제대로 인정받지 못한 청소년들이 자신의 주체적 목소리를 내고자 하는 데에서 그 의의를 찾을 수 있다. 근대적 규율, 학교 교육 제도 아래 묶여 있던 청소년들은 자신의 몸을 인식함으로써 자신만의 주체적인 목소리를 내고자 한다. 그 주체적인 목소리를 내는 지점에서 청소년 시는 시작되며, 이는 이전의 교육시와 다른 차별점을 갖는 부분이다. 청소년 시는 몸을 바탕으로 한 말하기를 시도한다. 어른들이 이성에 바탕을 둔 말하기에 기대는 반면, 청소년들은 몸에 바탕을 둔 말하기를 한다. 그래서 어른들과 청소년들은 서로 소통을 하는 데에 실패하고 만다. 청소년들은 어른들과의 소통보다는 자기 자신이 주체로 서는 것이 더 중요하다는 사실을 깨닫는다. 그래서 청소년 시는 청소년들의 삶을 하나의 성장 서사로 엮고자 한다. 이는 ‘이야기 시’의 형태를 취하거나 소설처럼 다양한 인물들이 등장하는 연작시의 형태로 구현된다. 또한 청소년 시는 세상에 대한 관심을 드러낸다. 그것은 청소년들의 노동, 탈학교 청소년의 이야기, ‘세월호’에 대한 언급 등으로 구체화된다. 다만 청소년 시는 그 시적 표현 기법이 아직 단순한 수준에 머물러 있어서, 표현 기법이 정형화될 우려가 있다. 또한 성인 작가가 청소년들을 대상으로 창작했다는 점에서 계몽에 대한 강박적 태도가 드러나기도 한다. 이러한 점은 청소년 시가 극복해야 할 한계점이라 할 수 있다. One of the remarkable phenomena in the literary world in the 2000s is the promotion of youth literature. Youth novels, in particular, have grown dramatically both quantitatively and qualitatively. However, juvenile poetry remained relatively poor. This situation is transformed by the publication of Park Sung-woo’s youth poetry 『I’m Red』 in 2010. Ten books were published for two years from 2015 to 2017 by Changbi Publishers’ youthful poetry series. It is necessary to examine the novelty and possibility of youth poetry as to how the youth poetry will be developed in the future with the publication of these juvenile poetry books. This paper examines the achievements and possibilities of Park Sung -woo poet’s two poetry poems and 10 poetry poems of youthful poetry series. Youth poetry contains the subjective voice of youths who have not been recognized for a long time. Under the modern discipline and school education system, young people who are tied up try to express their own subjective voice by recognizing their bodies. At the point of giving that subjective voice, the youth poetry starts, which is a differentiating point from the previous education poetry. Youth poetry tries to speak based on body. Adults expect to speak based on reason, while adolescents speak based on their bodies. So adults and young people fail to communicate with each other. Young people realize that it is more important to be self as a subject than to communicate with adults. So the youth poetry wants to make the life of the youth into a growth narrative. It takes the form of ‘story poetry’ or it is realized in the form of a serial version where various characters such as novels appear. Youth poetry also shows interest in the world. It is embodied by the youths’ labor, the story of the off-school youth, and the mention of ‘Sewol’. However, there is a fear that the poetic expression technique is still simple, and the expression technique becomes stereotyped. It also reveals the obsessive attitude toward enlightenment in that an adult artist has created for young people. This is a challenge for the youth poetry.

Dong-Su Bae,Chi-Eun Sung1,Hyun-Ju Bang,Sang-Pill Lee,Jin-Kyung Lee,In-Soo Son,조영래,Un-Bong Baek,Seung-HoonNahm 대한금속·재료학회 2014 METALS AND MATERIALS International Vol.20 No.4

During the use of API X70 steel as a pipeline structural material for the transportation of natural gas,hydrogen embrittlement can occur due to the hydrogen contained in natural gas. The aim of this study is toinvestigate the effects of the hydrogen content under high-pressure hydrogen gas conditions on the hydrogenembrittlement of air-cooled API X70 steel. The air-cooled API X70 steel was manufactured by hot rollingand was then air-cooled to room temperature. Tensile test specimens were held for 0 h, 1000 h, and 2000 hwithin a pressure vessel filled with 100% hydrogen gas at a gas pressure of 10 MPa, with the tensile teststhen performed at room temperature. The microstructure of the API X70 steel consists of coarse polygonalferrite, coarse pearlite, and fine acicular ferrite. The yield and tensile strength increased and elongationdecreased considerably after a holding time of 2000 h compared to those of 0 h and 1000 h within the pressurevessel. The morphology of the fracture surface changed from ductile to brittle upon hydrogen gas charging. Secondary cracks were observed in both of the hydrogen-gas-charged specimens. No external cracks wereformed on the surface of the tensile-tested specimen with a 0 h holding time; however, many external crackswere observed on the specimen surface subjected to hydrogen gas charging.

Objectives: The purpose of this study was to assess the correlation relationship between personal exposure and urinary hippuric acid in biological monitoring for airborne toluene in an industrial complex and in general environments. Methods: Personal exposure to toluene and its metabolite, hippuric acid, in urine were simultaneously measured in occupational environments area near an industrial complex and in general environments. The study subjects were divided into three types: 137 workers who use organic solvents in the workplace, 210 residents living near a dyeing industrial complex, and 379 residents living in general environments. The toluene exposures of workers and residents were measured by a passive sampler for four days. The urine of participants was sampled when the passive samplers of personal exposure were collected. Results: The toluene and hippuric acid concentrations of workers were the highest, followed by the concentrations of residents living near a dyeing industrial complex and residents living in general environments. The coefficient of correlation between the concentrations of toluene and hippuric acid among workers was 0.749 (p<0.01) in the workplace. On the contrary, correlations between the concentrations of toluene and hippuric acid among residents living near a dyeing industrial complex and residents living in general environments were all not significant. The relationship between the concentrations of hippuric acid and toluene in three types could be described by the exponential growth model. Conclusions: This study analyzed the relationships between toluene exposure and the concentrations of hippuric acid in urine in high, middle, and low exposure environments, and could be described by the exponential growth model.
