본 연구에서는 KI-188 칼슘과 KI-180 조성물이 성장발육에 미치는 효과를 조사하였다. 시험기간중 KI-188 칼슘과 KI-180 식이군이 대조군 보다 성장률과 평균 식이섭취량은 증가하였다. 체장은 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 평균 3.55 mm 더 길었고, 등뼈길이는 KI-180 식이군이 대조군 보다 통계적인 차이는 없었지만 0.5 mm 더 길었다. 대퇴골 무게는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 무거웠으며, 대퇴골길이는 대조군에 비해 각각 평균 0.89, 1.09 mm 더 길었다. 혈당, 총콜레스테롤 및 중성지방 농도는 차이가 없었고, 칼슘농도는 KI-188 칼슘과 KI-180 식이군 보다 대조군이 유의하게 높았다. 백혈구와 혈소판수는 차이가 없었고, 적혈구, 혈색소 및 헤마토크릿치는 대조군이 KI-188 칼슘과 KI-180 식이군 보다 통계적으로 높았다. ALP활성은 KI-180 식이군이 대조군 보다 통계적으로 높았고, osteocalcin농도는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 유의하게 높았다. 혈청 testosterone 농도는 KI-188 칼슘과 KI-180 식이군과 대조군 간에 차이가 없었다. IGF-1과 IGFBP-3 농도는 KI-180 조성물이 대조군 보다 각각 20%, 11% 정도 유의하게 더 높았다. 이상의 결과를 검토할 때 KI-188 칼슘과 KI-180 조성물은 어린쥐의 성장과 골격의 발달을 촉진시키고, 성장호르몬의 분비능을 양적으로 유도하여 전반적인 성장발육에 유효한 작용이 있는 것으로 사료된다. Herbs have active components that promote the growth rate of both animals and human. The KI-180 and KI-188 calcium food formulae contain Acanthopanacis cortex, Bombysis corpus and hoelen, seaweed calcium, chlorella extract, spirulina, colostrum powder, and other natural and functional components. We evaluated the growth-promoting effects of these formulae by analyzing the weight, femur and backbone, alkaline phosphatase, osteocalcin, testosterone, insulin-like growth factor (IGF)-1, and IGF binding protein-3 (IGFBP-3) of growing rats. Growing rats administered with KI-180 and KI-188 calcium showed the increase of body weight, body length, and femur weight and length of growing rats. In addition, administration of KI-180 and KI-188 calcium increased the alkaline phosphatase activity, the levels of osteocalcin and the growth hormones IGF-1 and IGFBP-3 of growing rats. The impact of KI-180 and KI-188 calcium on the physical development of growing rats suggests that the incorporation of these food formulae in the diets of growing children may promote the physical development.

이만홍,육기환 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.3

Objects : In order to define different concepts of narcissism in Korean, this study was designed to compare the concept of narcissism by Korean laymen with that of DSM-Ⅲ-R. Methods : 1) Initially, 2 laymen & 4 psychiatric personnel were interviewed and made to describe in free association on narcissism. With these results and the DSM-Ⅲ-R diagnostic criteria of narcissistic personality disorder, we developed a semistructured interview. 2) Using this semistructured interview, authors interviewed 28 key informants(14 laymen, 14 psychiatric residents) an asked them to describe their own understanding of prototypical person of narcissism. Psychiatric residents were comparative subjects to laymen. Results : Laymen thought positively that narcissism was one part of personality, made them achieve self-confidence and a new vitality in life, and consequently made them more enthusiastic in one's work. Narcissism was thught to result in possible difficulties of interpersonal relationships espeually by psychiatric residents. There was a gender difference which concentrated on the differences-men thought level of education, job, success, fame and money more important whereas women took as important factors such as appearance, relationships with one's spouse or lover and his social standing. Men overtly require acceptance by others whereas women self-absorption and intellectual achievement. When one is denied, men directly show aggressive response whereas women show this indirectly and later. Laymen saw narcissism as normal, while some saw it as a personality disorder or mental disorder. Reasons contribute to narcissism were developmental factor and socioenvironmental factor. Conclusions : Concepts and psychopathology of narcissism did not seem little difference between opinions of laymen and DSM-Ⅲ-R. Laymen took narcissism more positively than psychiatric residents. It was taken as part of personality, required for normal development and professional capabilities are above average and have achievement and self-confidence. Narcissism did not require treatment or when necessary it would become better. Results suggested that narcissism has sex difference more or less.

Raimon Blancafort & Man-ki Lee(2012), Reflexiones sobre la ensenanza del espanol en Corea y la implantacion de un sistema de control de la calidad, Estudios Hispanicos, 65, 33-61. El presente articulo no pretende ser un estudio academico basado en el marco teorico de la calidad educativa, sino que es una reflexion amplia sobre la situacion general de la ensenanza practica de lenguas extranjeras en Corea. El trabajo considera de forma general diferentes circunstancias relacionadas con el sistema educativo surcoreano, a la vez que expone logros y problemas presentes en la actualidad. No obstante, el proposito principal de este trabajo consiste en destacar que, a pesar del gran desarrollo experimentado, todavia existe margen para seguir avanzando y, asi, alcanzar un nivel de calidad educativa que posibilite la obtencion de mejores resultados academicos. En este sentido, se propone la creacion y el establecimiento de un sistema de control o gestion de la calidad aplicado al ambito educativo y, en concreto, a la docencia del espanol. En nuestra opinion, la aplicacion de un sistema que garantice la calidad en la ensenanza del espanol seria muy conveniente. Por todo ello, consideramos necesario reflexionar sobre la necesidad de incorporar y extender un modelo propio de gestion de la calidad adaptado a las circunstancias del pais, a las necesidades, caracteristicas y objetivos de los estudiantes y, tambien, a los requisitos de un mundo profesional cada vez mas exigente y competitivo.

The talus has some important anatomic features. Approximately 60% of its surface is cartilage and The talus often has problems with circulation. Talar neck fracture have a high association with ostonecosis and osteoarthritis. Authors have analysed l6 cases of the talar neck fractures treated at Lee-Rha General Hospital from January l990 to December l995 with minimal I year follow up. The results were as follows; 1. In thr l6 cases, there were l4 males and 2 females. the age between 20 and 40 years old was 10 cases(63%). 2. The most common cause of injury was traffic accident(63%), with sudden hyperextension as its mechanism. 3. associated injuries were 4 malleolar fracutres, 3 calcaneous fractures, 3 spine fractures, 3 tiviofibular fractures and 2 femur fractures. 4. According to the Hawkins classification: 3 cases in type I, 4 cases in type I, 5 cases in type l. 4 case in type N fractures were observed. 5. The method of treatment, all 3cases of Hawkins type I fractures were treated by closed reduction and cast immobilization, 3 cases of Hawkins type l and I case of Hawtins type III fracture were treated by closed reduction and internal fixation, other 9 cases were treated by open reduction and internal fixation. 6. Excellent results were observed in 8 cases good in 5 cases, fair in 2 cases . poor in l case with the Hawkins' therapeutic criteria. 7. Complications was observed 3 avascular necrosis, 2 post-traumatic arthritis, 2 ankle stiffness and l skin necrosis. From the above results, authors believe that early anatomical reduction k internal fixation is impotent to get a satisfactory result in de treatment of talar neck fracture.

Head Constraint on Spanish/English and Korean/English Code-Switching

Lee,Man-Ki 한국언어학회 2009 언어 Vol.34 No.2

In this paper, I am concerned entirely with code switching within sentences, i.e. intrasentential code switching. Specifically, this study examines Spanish/English and Korean/English code-switched utterences, in order to test "the Equivalence Constraint" proposed by Poplack (1980). I claim that the Equivalence Constraint cannot be a code-switching restriction on "word order mapping" between the two languages, because there are counterexamples in which, even if the word order is different between L1 and L2, the code-switching is possible if it does not involve the phrasal head. To explain these data, I propose Head Constraint on Code-Switching: If L1 has a unique phrase structure which is not shared with L2, the head which licenses the structure must be lexicalized in L1 while the other constituents can be randomly filled from either lexicon.

구토 후 발생한 토혈을 주소로 내원한 환자에서 좌측 늑막 삼출 동반 시 식도 파열의 가능성을 고려하여 흉수 천자 및 지속적인 흉부 단순 촬영의 추적관찰이 필요하며 식도 파열이 배제된 후 환자의 생체 징후 및 토혈 양을 파악하여 내시경 검사 시기를 신중히 결정하는 것이 좋을 것으로 생각된다. 본 증례는 토혈을 주소로 내원하여 Mallory-Weiss 증후군 의심 하에 내시경을 통한 치료 시행 후 추적 관찰에 의해 진단된 Boerhaave 증후군을 경험하였기에 보고하는 바이다. Boerhaave's syndrome is a spontaneous perforation of the esophagus most commonly resulting from a sudden increase in intraesophageal pressure combined with negative intrathoracic pressure caused by straining or vomiting. Surgery should generally be performed within 24 hours because mortality approached 30 to 50 percent in which surgery was delayed. Therefore, early diagnosis and prompt surgical repair are critical for survival. We have experienced a case of Boerhaave's syndrome in a patient presenting with hematemesis with left pleural effusion without any signs or symptoms of pneumomediastinum or pneumothorax.

李龍珍,金萬壽,朴東源,金英一,黃德基 東亞大學校 大學院 1997 大學院論文集 Vol.22 No.-

Liquid-liquid extractions by use of microporous hollow fiber modules are fast compared with conventional extraction equipment because of the large surface area per volume. In these modules, the extractant and feed can be contacted at high speed andtwo flows are completely independent, so there are no problems with loading and channeling. In this paper, it was investigated the extractability for liquid-liquid extraction of Cu(Ⅱ) from dilute aqueous solution into D2EHPA(di-2-ethylhexylphosphoric acid), TBP(tri-n-butyphosphate) and TOA(tri-n-octylamine) as organic extractants by using the hydrophobic hollow fiber module. To determine the dependence of mass transfer rate on distribution of Cu(Ⅱ) in the module, we compared the overall mass transfer coefficient with distribution ratio. From these experiments, we identified the effect of distribution ratio on the overall mass transfer coefficient was, for the low H, the K? was increased with increasing H, but high value of H, the effect of H on K? could be negligible.

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.
