Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

본 연구는 조선시대 유학자인 농암(農巖) 김창협(金昌協, 1651-1708)의 학문 수용 과정을 지각론을 중심으로 살펴본 것이다. 김창협은 율곡학파 계열의 학자이지만 퇴계 이황의 학설에 호감을 갖고 이를 긍정하여 자신의 학파와 절충하는 독특한 사상을 전개하였다. 율곡 이이의 사단칠정론에 대해 반대한 것은 아니지만 비판적 입장을 취하면서, 리발(理發)을 중심으로 하는 퇴계 이황의 이론을 수용하였다. 그것은 호락논쟁으로 이어지면서 김창협의 학문적 성숙을 유도하였고, 마침내 지각설이라는 이론 체계로 드러났다. 그의 지각론은 첫째, 성(性)은 성즉리(性卽理)의 입장에서 파악해야 하고 지(智) 또는 리(理)를 중심으로 해석해야 한다는 것, 둘째, 지(智)는 분별의 리(理)로 해석하는 것이 옳고, ‘밝게 비춘다’라는 구절의 해석에서 기미와 색상은 자연스럽게 드러난다는 점, 셋째, 지(智)는 사물의 시비득실(是非得失)의 차별을 구별하고 판단하는 기준이 된다는 점 등이 강조되었다. 다시 말하면, 인간은 사물을 접하게 마련이고, 심(心)의 지각은 이를 감각 기관을 통하여 받으며, 지각을 통해 받아들인 것은 인의예지신(仁義禮智信)의 성(性)에 의해 정해지고, 인간은 자신의 행동을 결정하며, 지는 인간의 내부에서 구체적인 정(情)의 작용인 측은지심, 수오지심, 사양지심, 시비지심의 모습으로 나타난다는 것이다. 이러한 인식은 인간을 주체이고 능동적 역할을 하는 존재로 부각시키는 사상적 근거가 된다. This research aimed to review the process regarding acceptance of studies about Nongam Kim Chang-Hyeop who was a confucian of Joseon Dynasty with the theory of intelligence and perception as the central figure. Being the scholar of Yulgok school, Kim Chang-Hyeop was interested in Toegye Lee Hwang`s theory, agreed with it, made a compromise with his school, and developed his unique thought. Although he did not object to Yulgok Lee Yi`s Sa Dan Chil Jeong Non(四端七情論, it is a theory regarding Sa Dan which are perfect virtue, righteousness, courtesy, and perception according to the theory of Mencius. and Chil Jeong which are pleasure, anger, sadness, joy, love, hate, and avariciousness), he took a critical attitude regarding it and accepted Lee Hwang`s theory with Li Bal(理發, appearing principle law) as the central figure. It was followed by Ho Rak Non Jaeng(湖洛論爭, it is an argument regarding whether human nature and thing`s nature are same or not), led the maturity of Kim Chang-Hyeop`s study, and finally appeared with the theoretical system of intelligence and perception. His theory of intelligence and perception emphasized that first, nature is perceived by "nature is principle law" and interpreted by intelligence or principle law. Second, it is right that intelligence is interpreted by principle law of discernment and smell, taste, and color naturally appear with interpretation of "shine brightly on." Third, intelligence is the criterion of discernment and judgement regarding differentiation of Si Bi Deuk Sil(是非得失, right, wrong, obtaining, and losing) about things. In other words, a person always faces any things, intelligence and perception of mind is arranged through sense organ, things accepted through intelligence and perception are determined by the nature of In Ui Ye Ji Sin(仁義禮智信, perfect virtue, righteousness, courtesy, intelligence, and trust), people determine their action, intelligence appears with the working of feeling which are Cheuk Eun Ji Sim, So O Ji Sim, Sa Yang Ji Sim, and Si Bi Si Sim. This perception becomes a foundation of thought which emphasizes human beings as a active role and a subject.

Trichloroethylene (TCE) is a toxic chemical commonly used as a degreasing agent, and it is usually found in a colorless or blue liquid form. TCE has a sweet, chloroform-like odor, and this volatile chlorinated organic chemical can cause toxic hepatitis, neurophysiological disorders, skin disorders, and hypersensitivity syndromes. However, the hypersensitivity pneumonitis (HP) attributed to TCE has rarely been reported. We hereby describe a case of HP associated with TCE in a 29-year-old man who was employed as a lead welder at a computer repair center. He was installing the capacitors on computer chip boards and had been wiped down with TCE. He was admitted to our hospital with complaints of dry coughs, night sweats, and weight losses for the past two months. HP due to TCE exposure was being suspected due to his occupational history, and the results of a video-associated thoracoscopic biopsy confirmed the suspicions. Symptoms have resolved after the steroid pulse therapy and his occupational change. TCE should be taken into consideration as a potential trigger of HP. Early recognition and avoidance of the TCE exposure in the future is important for the treatment of TCE induced HP.

This study was undertaken to investigate the pattern of distribution of adrenergic nerves in normal virgin, and the relatioships between the functions of adrenergic nerve and the female sex hormones changed peculiarly during pregnancy and post partum as previously reported by many authors. The reproductive organs were fixed in mixture of 4% formaldehyde and 0.5% glutaraldehyde and processed for fluorescent microscopy to show the catecholamine concentrations in nulliparous, pregnant(5, 10, 15 and 20 days), puerpheral(3, 7 and 15 days),and primiparous (30 to 45 days after parturition) rats. The result obtained in this investigation are summarized as followings. 1. In virgin uteri, catecholamine-fluorescence was visible intensely in the wall of vessels and their surrounding connective tissue and less intensely in myometrium than the vessels in all regions of reproductive tract. The intensity of fluorescence was higher In uterine cervix and tubal end of uterine horn than the main part of uterine horn. 2. In the pregnant uteri, the intensities of fluorescence did not changed at 5 days of pregnancy, but decreased gradually from 10 days to 15 days of pregnancy, and disappeared atmost completely in myometrium and small vessels except some of large vessels in perimetrium during the late pregnancy. 3. In lactating rats after parturition, the fluorescence was increased rapidly and almost completely restored by 15 days after parturition. 4. In the parous uteri at more than 30 days after parturition, the fluorescence showed slightly more intense than that in the nulliparous uteri. The above findings suggest that the alterations of catecholamine-fluorescence are much removed from the peculiar characteristic changes of the female sex hormonal levels during pregnancy and post partum. It is concluded that the alterations of catecholamine-fluorescence closely relate with the quantitative changes of uterine tissue during pregnancy and post partum, and having the experience of pregnancy and parturition, the uterus attain to maturity.

Glomus tumors are benign neoplasms that are derived from modified smooth muscle cells known as glomus cells. Histologically, it can be subdivided as glomus tumor proper, glomangioma, and glomangiomyoma according to relative proportions of components. Glomangiomyomas are the least frequent type and their overall architectural pattern may resemble glomus tumor proper or glomangioma, but there is a gradual transition from glomus cells to elongated mature smooth muscle cells. This transition is most obvious in the region surrounding large vessels. We present a case of glomangiomyoma of the left upper arm and the left fourth finger, in which ten-year history of two painful, bluish-colored subcutaneous nodules. On histologic examination, this case showed marked smooth muscle cell proliferation around large vessles and mucinous stromal change. (Korean J Dermatol 2001;39(10) 1147-1151)

The purpose of this study was to investigate the change of the peak torque, average power and total work of muscle function in the fatigue during eccentric(ECC) and concentric contraction (Con). Subjects were seven (7) adults man, who were paticipated in the ECC and CON experiments. Their gastronemus muscle were measured by CYBEX(Lurnax Co.) 6000system. Muscle fatigue was induced by 50 repetitionplantar flexion at 180 /sec load speed. In pre and post test, peak, average power and total work were analized when subjects were tested plantar flexion at 180/sec load speed. the summary of this results is as following : 1. Peak torque in the ECC were significantly higher than that of the CON. 2. Average power and total work of the Eccentric contraction appeared a higher than that of the Concentric contraction significantly. As a results. peak torque, average power and total workin the ECC was significantly higher than that of the CON throughout the experiments. In this fact, Mechanical efficiency in the ECC will expect to be higher than that of the CON.
