This paper presents the analysis of the analysis of thrust characteristics of linear induction motors(LIMs) according to secondary reaction plate. LIMs are well known as high speed transport systems, which can obtain thrust directly without gears and links, or auxiliary mechanisms. A simple structure, easy maintenance, and less environmental pollution are advantages of LIMs. In transport systems using LIMs, the secondary reaction plate is an important design factor, because it has considerable impact on the cost of the railway as well as the performance of the LIMs. This paper deals analyzed the characteristics of linear induction motor used for moving the vehicle of container scanner. Thrust, efficiency and load characteristic were interpreted with FEM regarding two models whose material of secondary reaction plate was copper and aluminum. It suggested the interpretation of thrust, efficiency and power factor characteristic along slip and compared the operation ability of linear induction motor through characteristics analysis along the load.

사회적 형평성의 개념적 심화를 위한 정의론의 비교연구

임의영(Lim Euy-Young) 서울행정학회 2003 한국사회와 행정연구 Vol.14 No.2

This article is to develop a concept of social equity. Since the 1970s, a little attention to the social equity has been paid. Generally academicians and practitioners in public administration think of the concept of social equity as ‘justice as fairness’ of J. Rawls. The social equity as a concept is based on the theory of justice. Theories of justice are very various. Therefore the concept of social equity should be developed by studying the various theories of justice. But academicians of public administration did not investigate the relationships between social equity and the various theories of justice except Rawls' theory. So this article is to study comparatively the theories of justice of R. Nozick, M. Walzer, and M.I. Young, who were influenced by Rawls. Entitlement theory of Nozick based on the liberalist position, theory of complex equality of Walzer based on the pluralism, and politics of difference of Young based on the multiculturalism are significant thinking points to develop the concept of social equity.

A survey was performed to 250 male young men who were living alone and shared living with friends in Chungnam province. Their average age was 22.6 years old, height was 171.8 cm, weight was 65.6 kg and BMI was 22.2 Comparing the prevalence of drinking, smoking and exercise, there were significantly different between living alone subjects and shared-living ones. The main value toward eating/meals was for hungry soultion. And we found many significant differences by living with or without companion. When young men living without companions, they shouved to be more in regular mealtimes, no-skipped meals, breakfast eating, adequate food amounts, eating-outs, etc. and to be less in pleasant mealtimes, various foods, snacking and especially late snacks. The good food intake pattern were highly scored in the alone-living group than the shared-living group, whereas the bad food intake pattern were also highly scoued in the alone-living group than the other. The latter might be due to the more food exposures because of companions. These findings could conclude that dietary behaviors of the young living alone were evaluated as good enough.

일제강점기 한국 근대문학에 나타나는 다방공간의 재현 양상 - 소설 장르를 중심으로 -

임영봉(Lim, Young-Bong) 우리문학회 2021 우리文學硏究 Vol.- No.70

일제강점기 다방 혹은 카페 공간의 문학적 재현 양상은 서구의 차(茶)문화가 유입되고 발전해나가는 문화사적 배경 속에서 이해될 필요가 있다. 1910년대 이후, 본격적으로 유입되는 홍차와 커피 중심의 ‘다방문화’는, 술과 여급이 중심이 되는 일본식 ‘카페문화’의 대두 현상에 의해 서서히 퇴조했다고 볼 수 있다. 이에 따라 다방공간의 재현 양상도 초기의 근대적인 감수성과 이국적 정취 중심의 상상적 내면적 의미를 띠는 이미지에서, 술과 여급이 등장하는 유흥 중심의 일상적이고 퇴행적인 의식을 담고 있는 이미지로 변화해 나갔다. 이광수의 신문연재소설 <개척자>(1917)는 커피라는 서구적 기호품이 수용되는 과정의 풍속과 현실을 잘 보여주고 있는 경우이다. 1920년대에 발표된 박영희의 <백수의 탄식>과 정지용의 <카페 · 프란스>는 서구적 감수성과 이국 취향의 정서에 지배되는 다방문화 수용 초기의 이미지를 보여주고 있다. 이 두 편의 시 작품은 근대적 문화공간에 대한 수용이 이념에 따라 굴절되는 이후의 양상을 예고하고 있다는 점에서 주목을 요구한다. 일제강점기 소설의 다방공간에 대한 재현은 이광수와 염상섭, 채만식같은 작가를 비롯하여 ‘카프계열’의 박영희와 김남천, ‘동반자 작가’였던 유진오와 이효석, ‘구인회’의 박태원과 이태준, 이상 등의 작품에서 다양한 양상으로 나타나고 있다. 일제강점기 한국 근대소설에 그려진 다방공간은 인간 존재가 뿌리를 내리고 안주할 수 있는 원초적 장소의 상실 국면, 즉 ‘집’이면서 ‘고향’이거나 ‘조국’으로도 상징될 수 있는 삶의 장소 상실에 대응하는 정신적 표상으로 나타나고 있다. 일제강점하의 상황에서 다방이라는 공간은 뿌리를 상실하고 떠도는 존재의 피난처인 동시에 자신의 내밀한 꿈을 보호하고 실현해나가는 내면적 상상적 장소라는 의미를 가지고 있다. 박태원의 <방란장 주인>에 나타나는 헤테로토피아적인 이상향의 이미지는 이러한 측면을 잘 보여주고 있는 경우이다. The literary representation of tea rooms or cafés during the Japanese colonial era needs to be understood from the cultural background of the introduction and growth of Western tea culture in Korea. The “tea room culture” (based on black tea and coffee), which was introduced in earnest starting in the 1910s, slowly disappeared with the emergence of the Japanese “café culture,” featuring mostly alcohol and barmaids. Accordingly, the representation of the tea room underwent a transformation from its early image with an imaginative, inner meaning centered on the modern sensibility and an exotic atmosphere to a quotidian and decadent image centered on entertainment, permeated by the odor of alcohol served by barmaids. The first work identified thus far featuring the tea room is Lee Kwang-soo’s Pioneer(1917), a serial novel published in a newspaper. This work illustrates the customs and reality of a time when the Western culture of coffee was introduced. Park Young-hee’s Sigh of the Jobless and Jung Ji-yong’s Café France, published in the 1920s, show images of the early years of the tea room culture when it was dominated by Western sensibility and exotic tastes. These two poems call for attention because they foretell how the introduction of modern cultural spaces is affected by ideology. Representations of the tea room during the colonial era are found in different forms in works such as those of Lee Kwang-soo, Yeom Sang-seop, and Chae Man-sik; Park Young-hee and Kim Nam-cheon of the Korean Federation of Proletarian Art (KAPF); Yoo Jin-oh and Lee Hyo-seok, who were sympathizer writers; and Park Tae-won, Lee Tae-joon, and Lee Sang of the Guinhoe (Nine Person Association). The tea room depicted in novels during the colonial era corresponds to a mental representation expressing the loss of the primal place where people can take root and settle down, i.e., the loss of a living space symbolized as a “house,” “home,” or “fatherland.” Under colonial rule, the tea room signified a temporary shelter for wandering people without roots and an inner, imaginary place that protects and realizes one’s intimate dreams. The heterotopian image in Park Tae-won’s The Owner of Bangranjang is a case in point.

실험적 진폐증에서 투여약제에 따른 면역학적 병리학적 조직변화

윤임중,임현우,노영만,오상용,정장영,임영,김경아 가톨릭 대학 산업의학 쎈타 산업의학연구소 1993 韓國의 産業醫學 Vol.32 No.2

To access the effects of some drugs such as piperazine phosphare, azathioprine and allopurinol in the experimental pneumoconiosis, 263 rats weighted 240-320 gm was divided into the control and eight experimental groups. To each group, the turbid solution mixed free silica, talc and natural coal dust of 50 mg in 0.8 ml saline were instilled intratracheally. At the begining and 5th week of experiment, piperazine phosphate(8mg/week orally), aspirin(1.5mg/day intramuscularly), azathioprine(25mg/day orally) and allopurinol(1.5mg/day orally) were administered simultaneously, while the dust turbid solution was only given to the control group. For each group the change of body weight. dry right lung weight, cellularity including total cell, macrophage, lymphocyte and neurtrophil in bronchoalveolar lavage fluid, superoxide ion, hydroxyproline, leukotriene B₄, tumor necrotsis factor, prostaglandin E₂were examined, and observed the pathological chages in lung tissue. The results were as follow : 1. The larger amount of their instilled dust and the longer observation period, the severer pathological findings were found in the lung tissue of each experimental group. 2. The body and dry right lung wight was not significantly changed in the experimental groups compared with the control group. 3. The number of total cell in bronchoalveolar lavage fluid was markedly less in the experimental group than the control one, while no significant difference was found in the percent alveolar macrophages and lymphocytes in both groups. However, the percent of neutrophiles was usually lower than in the control group. 4. The amount of superoxide ion was frequently less in the experimental group compared with the control one. 5. The amount of hydroxyproline was significantly lower in the experimental group than in the control one. 6. The amount of leukotriene B₄was usually less in the drug administered group than in the control one. 7. The amount of tumor necrotic factor was also frequently lower in each experimental group than in the control one. 8. The amount of prostaglandin E₂was usually higher in each experimental group than in the control one.

『천의소감(闡義昭鑑)』에 대한 서지적(書誌的) 연구

임기영 ( Kee Young Lim ) 경북대학교 영남문화연구원 2011 嶺南學 Vol.0 No.19

조선 후기 당쟁서를 언급할 때 빠뜨릴 수 없는 자료 중의 하나가 『闡義昭鑑』과 『戡亂錄』 및 『明義錄』의 간행이다. 이러한 저술들은 한결같이 내적 분쟁의 혼란 속에 이루어졌고, 따라서 그 출판의 동기도 대등소이하다. 그 중 특히, 『闡義昭鑑』은 영조의 집권 중반에 중앙의 집권층에서 반대 세력을 다스리고, 집권층의 대의명분을 표명하기 위한 임금과 중앙 관료들이 이루어낸 의도적인 출판의 결과물이다. 이 연구는 이처럼 영조대에 이루어진 『闡義昭鑑』의 편찬과 간행 과정, 그리고 후속 작업으로 의궤의 작성까지 이어진 조선 후기 관찬서의 출판 과정을 서지적 관점에서 다루었다. 그리고 무엇보다 이러한 자료의 출판이 이루어지기까지 당시 임금과 중앙 관료들의 구체적인 업무 논의, 진행 절차와 과정을 사료와 관련 기록을 토대로 소급하여 살펴보고자 하였다. 이러한 검토 작업은 18세기 중엽 임금 주도로 추진된 관찬서의 간행 과정을 정리하고, 그 구체적인 모습을 재구성하여 본다는 측면에서 의미가 있을 것으로 판단된다. This study dealt with the book 『CheonEuSoGam(闡義昭鑑)』 which is related Party strife book in the late period of Chosun Dynasty. 『CheonEuSoGam(闡義昭鑑)』, 『Gamranrok(戡亂錄)』 and 『Myungeurok(明義錄)』is representative book which related with political party strike in 18th. Especially 『CheonEuSoGam(闡義昭鑑)』 is published with the aim of suppression to opposition party and representation of judification in ruling party, including King Young-jo(英祖) So this study is focused at the process of compilation and publication details with 『CheonEuSoGam(闡義昭鑑)』. Besides, we examined the publication of Korean annotation version and the completion of Eugye(儀軌) to that book. Chansoochung-Eugye(纂修廳儀軌) reveals the participants and pay of the people, and the list of articles used with the publication, that is paper, brush, ink stick, desk, stool, beeswax, etc. Therefore the Chansoochung-Eugye(纂修廳儀軌) is the most important material that notify the related factor of 『CheonEuSoGam(闡義昭鑑)』. To achieve this, we tried to investigate detail discussion between King Young-jo(英祖) and central courtier, publication progress and stage, every other process related with the publication of 『CheonEuSoGam(闡義昭鑑)』 This kind of examination in our study allows us to arrange the process of book publication at central government of late period in Chosun Dynasty. Also it helps the composition of actual proceedings in book publication at that times.

박영진가 개성부기 장부의 분석과 특징: 제1기 거래를 중심으로

정기숙 ( Key-sook Jung ),노병탁 ( Byung T. Ro ),김영화 ( Young-hwa Kim ),임상종 ( Sang-jong Lim ) 한국회계학회 2023 회계저널 Vol.32 No.3

박영진가의 개성부기 장부는 24년 8개월간(1887. 8.15. ~1912. 4.15.)의 상거래 활동을 기록한 회계장부이며 일기장, 장책, 주회계 및 각인회계장부 등이 현존하고 있다. 이 장부는 박영진의 4대조부터 개성에서 사업을 경영한 개성상인의 장부라는 것이 확인되었다. 일기장의 기입원리는 복식부기의 기본원리인 거래의 이중성과 대차평균원리를 따르고 있다. 상거래 분개는 현금 중심으로 기입되어 있고, 분개 방식은 현대의 은행부기의 기입 방법과 유사하며, 일기장은 현금출납장의 기능을 가지고 있다. 자산과 비용의 증가는 입(入)을, 감소는 거(去)를 사용하고, 부채 및 자본과 수익의 증가도 입(入), 감소는 거(去)를 사용한다. 현대 복식부기에 비해 미흡한 점은 이자수익에 대한 회계처리이다. 대여시점에 이자수익을 미리 계산하지만 일기장에 기입하지 않고 장책에 미수이자, 즉 채권으로 기입하고 있다. 따라서 장책에 의해 시산을 하면 대차평균원리가 지켜지지 않는다. 이자수익에 대한 용어와 인식시점도 도중(또는 차인)과 여타 거래처와 다르다. 도중의 경우는 대거라는 용어를 사용하고, 여타 거래처는 채급이라는 용어를 사용한다. 미수이자에 대한 기입도 대거의 경우는 결산 시에 기입하고, 채급의 경우는 대여와 동시에 기입한다. 박영진가의 결산 시기는 매년 9월 15일이며 결산 시에 장부마감 절차를 취하지 않고 계속 기입하고 있다. 1916년에 발간된 현병주의 개성부기 책에 있는 예시에서는 결산기에 장부마감 절차가 있고, 장책의 경우 새 장부를 사용하지 않고 계속 기록할 때는 권점(○)을 표시하여 구분을 하고 있다는 점에서 차이가 있다. 그리고 질(계정)간에 대체거래가 있는 경우 일기장을 거치지 않고 장책에서만 이록과 이래라는 용어를 사용하여 이체된 기록임을 나타낸다. 요약하면 이자수익에 대한 회계처리와 결산마감 절차가 지켜지지 않는 것이 박영진가 장부의 단점이라고 할 수 있다. 그러나 박영진가의 개성부기장부는 앞에서 지적한 미비점을 제외하고는 개성부기, 즉 복식부기의 원리에 따라 정리되어 있다. It is well known that the ancestry of Park Young-jin's family was one of the Kaeseong merchants in the area of Goryeo (AD 918-1392) and the descendants of the family still keep an almost complete set of the original books of Kaeseong bookkeeping. Collectively, these books cover a vast volume of records on the business transactions of the family over a period of 24 years and eight months(AD 1887. 8.15. ~ 1912. 4.15.). They consist of Ilgee Jang, Jangchaek, Ju Hoegye, and Kagin Hoegye, among others. All these books are the genuine and original books of Kaeseong bookkeeping. The records in Ilgee Jang are prepared according to the double entry principle or, more generally, the duality of business transactions and the balancing feature of debits and credits. The journal entries are made largely in line with the cash basis of accounting and the principles of bank accounting today. As such, Ilgee Jang is more like a ledger for cash transactions. The increase (decrease) in assets and expenses is recorded and indicated by the letter 去(入). And the increase (decrease) in liabilities, equity, and revenues is recorded and indicated by the letter 入(去). One thing of particular interest, which may be a potential limitation of the Park family books, is that the entry to record interest revenue on loans is not made clear. That is, the interest revenue on loans is computed in advance as the loan is made yet the record thereof is not found in Ilgee Jang but found in Jangchaek later. Because of this, a period-end general trial balance, if prepared, does balance the debits and credits. Another ambiguity is that the entry of interest revenue is not made consistently between Dojung (or Chain) versus other business customers. In the case of the Dojung Hoegye, for example, the term Chaegeup is used to indicate the interest revenue on loans, while another term Daegeo is used in other cases. And In the case of Chaegeup, the entry of the interest revenue is recorded at the time when the loan is made. In the case of Daegeo, however, the interest revenue is recorded when the loan is paid off at the end of the accounting period. The accounting period of the Park Young-jin family business typically ends September 15 each year. However, the books are not closed at each period-end but still left open for the next period. This is somewhat confusing or contrasting to the book (1916) of Hyeon Byeoing-ju on Kaeseong bookkeeping. In his book, Hyeon shows how to close the books at year-end. For example, he shows that the Janchaek of each year is closed and a new Jangchaek is used for the next year. In cases where the same Jangchaek continues to be used in the next period, the individual accounts are marked with the symbol O called Kwonjeom. And if there is any transfer transaction between individual accounts, it is recorded only in Jangchaek, indicated by the word Eerok or Eerae. In summary, the recording of interest revenue on loans in books and the lack of the year-end closing procedures for books in general are the most notable limitation of the Park family books. Other than this, the Park family books are the most complete set of accounting books on Kaeseong bookkeeping in existence, prepared largely according to the double entry principle we use today.

Effects of I- and W-Phases Under Identical Conditions on Microstructure and Mechanical Properties of As-Cast Mg–Zn–Y Alloys at Room and Elevated Temperatures

Young‑Gil Jung,Wonseok Yang,Jae Ik Hyun,Shae K. Kim,Hyunkyu Lim,Do Hyang Kim 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.12

Three alloys (Mg–6Zn–1.2Y, Alloy I; Mg–3.65Zn–1.65Y, Alloy II; and Mg–4.3Zn–1.4Y, Alloy III) with same volume fractionand grain size were designed to evaluate the effects of the I-phase (Mg3Zn6Y) and W-phase (Mg3Zn3Y2), which are themajor phases in Mg–Zn–Y alloys, on the mechanical properties. The tensile strength of Alloy I with the I-phase at roomtemperature was the highest among the tested alloys because the coherent interface between the I-phase and the α-Mg phasewas more resistant to cracking than the incoherent interface between the W-phase and the α-Mg phase. A cross-sectionalmicrostructure analysis of a sample that was tensile-tested at 423 K revealed that the morphology of the I-phase remainedrelatively stable. In contrast, the W-phase was broken and fragmented during the tensile test at 423 K because it had higherbrittleness under the test conditions. Therefore, the tensile and creep properties of Alloy I at 423 K were better than thoseof Alloys II and III containing the W-phase. According to the results, the I-phase in the Mg-Zn-Y alloy was more beneficialto the mechanical properties at room temperature and 423 K than the W-phase.

Poly(vinyl alcohol) nanocomposites containing reduced graphene oxide coated with tannic acid for humidity sensor

<P><B>Abstract</B></P> <P>Poly(vinyl alcohol) (PVA) nanocomposites were prepared by a solution casting method using a reduced graphene oxide coated with tannic acid (rGO-TA) as a filler. The rGO-TA was simply prepared by mixing tannic acid (TA) with graphene oxide (GO). The simple mixing process was found to be effective to reduce GO and to produce covalently-grafted TA layers on the reduced GO. The mechanical properties of PVA were much improved by the addition of rGO-TA because the TA layers increased the compatibility of the reduced GO with PVA matrix. For example, Young's modulus and elongation at break values of PVA were increased by 34.0 and 56.9%, respectively, by adding 1.0 wt% of rGO-TA. In addition, the PVA nanocomposites showed excellent humidity sensing properties over the wide relative humidity range and the long-term stability due to the conductive property of the reduced GO and the enhanced mechanical strength by the effective incorporation of rGO-TA into the PVA matrix.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The rGO-TA was prepared by a facile and green method using a low-cost tannic acid. </LI> <LI> The effect of rGO-TA on the properties of PVA nanocomposites has been studied. </LI> <LI> The rGO-TA improved the important properties for PVA-based humidity sensors. </LI> <LI> The PVA/rGO-TAs are promising materials for high-performance humidity sensors. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

흡연자와 비흡연자의 타액에서 코티닌 정량 및 ETS 노출량 평가

임흥빈,강영국,손형옥,이영구,문자영,이동욱 충북대학교 엽연초연구소 2001 煙草硏究 Vol.18 No.-

This study was conducted to measure and compare the salivary cotinine concentration between smokers and nonsmokers, and to investigate the effect on the exposure to environmental tobacco smoke(ETS) with housewives, living on an apartment of Korea. Saliva samples were taken from all volunteers and salivary cotinine was analyzed by a developed radioimmunoassay(RIA) method. The median salivary cotinine levels were 52.8±12.6 ng/ml and 44.6± 9.7 ng/ml in male smokers and in female ones, respectively, and they were 4.3±2.1 ng/ml and 2.9±3.1 ng/ml in male nonsmokers and in female ones, respectively. In addition, average salivary cotinine levels were 3.8±2.7 ng/ml in housewives from smoking homes and 2.4±2.4ng/ml in ones from nonsmoking homes. Results obtained from the analysis of salivary cotinine demonstrate that smokers had a significantly higher concentration of salivary cotinine than nonsmoker. But, there was no significant difference in the salivary cotinine concentration for housewives living in apartment between with smoking husband and with nonsmoking husband.
