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.

Lim,Hyun-Sung,Yoon,Tae-Gyeong 한국통합사례관리학회 2021 한국케어매니지먼트연구 Vol.- No.38

This study s purpose was to examine the impact of loneliness, and two types of social support(functional and structural) on the suicidal ideation among elderly living alone. About 254 research participants were recruited from Seoul City and other cities in Gyeonggi-do and finished the questionnaires of loneliness, perceived social support, structural social support, and the suicidal ideation. Data were entered into multiple regression analyses. The finding of this research study indicates that loneliness was an important predictor for suicidal ideation. Thus, increased loneliness was associated with a high level of the suicidal ideation. This research study result showed a moderating effect of functional social support. However, structural social support did not moderate relationship between loneliness and suicidal ideation. This research study would provide implications for social work practices.

Lim,Jung-Dae,Yang,Deok-Chun,Lee,Hyeon-Yong,Kim,Jong-Dai,Lee,Jin-Ha,Sung,Eun-Soo,Yu Chang-Yeon 한국자원식물학회 2004 Plant Resources Vol.7 No.1

The establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L^-1 and 0.1 mg NAA L^-1. Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.

우리나라 綿織物의 史的 考察

임성휴,신인수 圓光大學校大學院 1996 論文集 Vol.17 No.-

This thesis studied among India, the cradle of cotton fabric culture, its outskirts eastern Asia, China, Korea and Japan, mutual relations of cotton fabric cultural formation and the development process of cotton fabric production. The cotton fabric culture originated from India about 2500 B.C. and spread to Asia including Korea, Europe and throughtout the world. It also had developed and settled according to the trait of those regions. It was in 1362, the twelfth1 year of King Kongmin, at the end of Koryo dynasty that Mun Ic-Jeom brought into cotton seeds from the Won Country (one of Chinese dynasties) however in the three-kingdom age as people traded with those of Min (민)(Bok Gun Sung, 福建省) and Kwang(廣)(Kwang Dong Sung, 廣東省) provinces of China, they was able to product 'Baik chup po(白疊布·白첩布, a kind of textile)' with brought-in cotton from China by using their skill of fine cotton-spinning. Baik chup po was sent to China as a tribute in three-kingdom rige and Koryo dynasty on the other side Baikjae dynasty sent 'Baik Myun(白綿, a kind of cotton fabric)' to Japan and affected the Japan cotton fabric culture. In Chosun age cotton fabrics became universal and ranked as main cloth, but they were collected severely as taxes and there were a variety of prohibitive measures of clothes according to their social positions. The cotton fabric industry didn't come to develop qualitively and stayed at a domestic hand-operating industry until the late of Chosun dynasty. For those reasons in the enlightened age, it declined Chosun textile manufacturing company in 1917 due to excellent (superior) imported cotton fabrics but as Kyungsung textile manufacturing company in 1919 were established, gradural cotton-production industrialization started. After that our country's cotton industry developed consecutively and in the 1960's it made a great contribution to the development of nation economy. In the 1990's as the stage of automatization on the one hand they try to promote productivity and the other hand, according to developed countries' diversification and differentiation trends they make effors to develop the advanced new material.

임길택의 아동문학과 초등학교 문학교육에의 시사

임성규 한국초등국어교육학회 2008 한국초등국어교육 Vol.38 No.-

최근 들어 아동문학에 대한 대중적 관심의 증가로 인해 아동문학 연구 담론 확충의 현실적 필요성과 아동문학 교육 담론의 체계적 이론화에 대한 사회적 요구가 확대되면서 아동문학을 둘러싼 학문적 발전이 가속회되고 있다. 그러므로 이러한 시대변화의 환경 속에서 초등학교 문학교육 연구가 한걸음 전진하기 위해서는 아동문학 연구 및 한국 아동문학의 전통성과의 긴밀한 연관 관계 회복을 통해 새로운 발전적 시사를 확보해 나가야한다. 왜냐하면 아동문학은 근본적으로 초등학교 문학교육의 원천을 이루고 있기 때문이다. 그런 의미에서 임길택의 아동문학과 아동문학 교육 활동은 아동 고유의 독자적 시각을 통해 본 삶의 다양한 이면과 진실을 핍진하게 반영하고 있다는 점에서 초등학교의 문학교육을 위한 새로운 시사를 담지하고 있다. 곧, 현재 문학교실에서 이루어지고 있는 교육 활동의 협소한 체험의 범위와 소재의 제한성을 넘어서는 발전적 동인을 품고 있을 뿐만 아니라 기존의 문학적 글쓰기 교육이 지닌 한계를 극복할 수 있는 표현력 고양을 위한 단초를 내장하고 있는 것이다. 실제로 지금까지 초등학교 문학교육은 많은 발전을 이룩하였지만, 아동문학 전통과의 연관 맺기는 새롭게 탐구해야 할 과업으로 남겨져 있다. 그러므로 초등학교 문학교육 이론의 보완과 실천력 확보를 위해서는 전통 아동문학 주체들에 대한 탐구와 함께 그들의 삶과 문학이 담지하고 있는 교육적 시사들을 현재적 관점에서 재검토하는 작업들이 이어져야 할 것이다. This paper aimed to finding suggestion to elementary school literary education through Lim Gil-Taek's children's literature. Recently, academic expansion of children's literature is accelerating for increase of popular concern and realistic need of study discourse amplification. So, elementary school literary education have to recover closer connection with children's literature study and Korean children's literature tradition in changing environment. Because children's literature is basically source of elementary school literary education. In this point, Lim Gil-Taek's children's literature have new suggestion for literary education. It reflect the truth of life and children's inherent eye.That is developmental motive that conquer narrow experiencing scope and limitedness of material. And, it has clue of expressive competence that cross pre-existing literary writing education. Actually, extension of elementary school literary education need to linking to children's literature tradition. Theoretical complement and security of practicing competence have to start inquiring traditional children's literature main-body.

Extension of Lance Life by Change of Height of Lances in the Smelting Furnace of Mitsubishi Process

Sung‑Mi Lim,Soo‑Sang Park,Kyung‑Woo Yi 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.10

A Mitsubishi process, which pertains to continuous Cu production, involves a smelting furnace, cleaning furnace, and convertingfurnace connected in series. One of the main issues pertaining to the smelting furnace is the frequent interruption ofoperations required to allow the inspection and replacement of lances, because lances are frequently fractured. The presentstudy was aimed at modifying the operating conditions of the smelting furnace to suppress lance fractures. A numericalmodel was developed to simulate the transport phenomena in the furnace, including multi-phase behaviors. The simulationresults showed that the lances were exposed to a severely erosive atmosphere with high temperatures. Further calculationindicated that raising the positions of the lances could lower the temperature of the lances, and reducing the occurrence ofsplashed melt, which contains erosive sulfides. The smelting furnace was operated under the conditions of the raised lanceheight and attentively monitored for several months. It was confirmed that by implementing such a change of the lanceheights, the occurrence of lance failures has been considerably reduced without notably affecting the reaction ability of thesmelting furnace.
