이 논문은 퇴계의 한시에 나타난 대나무의 형상사유와 미의식을 연구한 것이다. 퇴계는 조선을 대표하는 성리학자인 동시에 약 2000여수의 한시를 남긴 조선중기 사림의 대 문호였다. 이 시기 조선 사림들의 예술 경향 속에는 사군자로 지칭되는 절개와 지조의 상징물들이 독특하게 나타나 조선 사림의 예술을 선도하였다. 시․ 서 화를 통한 사군자의 예술지향은 성리정신과 조화를 이루며 한 시대를 풍미하 게 되었다. 이 중심에 퇴계의 대나무에 대한 한시가 있었다. 퇴계는 동아시아의 문학사에서 대나무를 형상화한 다양한 장르의 문예들을 접하고 이들을 바탕으로 대나무를 문학적으로 새롭게 인식하기 시작했다. 퇴계는 대나무를 직접 가꾸기도 하고 완상하기도 하면서 대나무를 비유와 상징의 수법으로 형상화 했으며, 당시에 유행하던 대나무 그림위에 제화시를 남기기도 했다. 그의 대나무 한시에는 다양한 미의식이 함의되어 있다. 그가 주창한 대나무 이미저리는 주로 선비의 굳은 지조 와 곧은 절개를 상징한다. 퇴계의 대나무 한시에는 꿋꿋하고, 맑고, 깨끗하고, 강 인하고, 의젓한 이미지를 그려낸다. 그의 대나무를 소재로 형상화한 시 속에는 枯淡, 拙樸, 苦拙, 淸眞등의 楚楚한 풍격의 미의식이 함의되어 있다.
The purpose of this study was to investigate the most effective and comprehensible method for the assessment of resting scapular position (RSP) and pain level (PL) in unilateral shoulder pain (USP). Fifty volunteers with USP were involved in the study. Resting scapular assessments of the patients' pain sides (PS) and non-pain sides (NPS) were evaluated. The assessment tools for RSP are: 1) sternal notch (SN) to coracoid process (CP) distance 2) 3rd thoracic spinous process (T3S) to posterolateral angle of acromion (PLA) distance 3) scapular index 4) 8th thoracic spinous process (T8S) to inferior angle of scapular (IAS) distance 5) supine measurement of pectoralis minor (PM) distance 6) standing PM distance 7) PM index (PMI) and 8) PM pain. The paired t-test was used to compare PS and NPS in RSP. Pearson correlation analysis was used to confer a relationship between the PL and RSP. The results of this study indicated that: 1) all the variables between the PS and NPS for RSP were statistically significant(p<.05) and 2) the PMI showed the strongest relationship in the correlation analysis between RSP and PL(p<.05, r=.37). Therefore, it can be concluded that there is a relationship between PMI and PL and it is suggested that an assessment tool using PMI to diagnose shoulder pain would be clinically effective.
To develop effective training methods for strengthening a weakened quadriceps femoris muscle in hemiplegic patients, we examined the effects of maximal isometric contraction of the nonparalyzed knee joint on the electromyographic activities of the paralytic muscle. An electromyogram (EMG) was used to record the electromyographic activities of the paralytic quadriceps femoris muscle in 27 hemiplegic patients. The maximal isometric contraction was measured for each subject to normalize the electromyographic activities. The maximal isometric extension and flexion exercises were randomly conducted when the knee joint angles of the nonparalyzed knees were 0˚, 45˚, and 90˚. The patients were encouraged to maintain maximal isometric contractions in both knee joints during each measurement, and three measurements were taken. A one-minute rest interval was given between each measurement to minimize the effects of muscle fatigue. An average from the three values was taken as being the root mean square of the EMG and was recorded as being the maximal isometric contraction. The electromyographic activity obtained for each measurement was expressed as a percentage of the reference voluntary contraction, which was determined using the values obtained during the maximal isometric contraction. The results of this study are summarized as follows: First, when the knee joint angle of the nonparalyzed knee was 0˚, the electromyographic activities of the paralytic medial aspect of rectus femoris were related to measurement by a maximal isometric flexion exercise than by an extension exercise (p<.05). Second, when the knee joint angle of the nonparalyzed knee was 90˚, the electromyographic activities of the paralytic lateral aspect of rectus femoris were related to measurement by a maximal isometric flexion exercise than by an extension exercise (p<.05). The results show that myoelectrical activities of paralytic quardriceps were not related to measurement angles and exercise directions of the nonparalized knee joint. Studies on various indirect intervention to improve muscular strength of patients with nervous system disorders of the weakened muscle should be constantly conducted.
Oral squamous cell carcinoma (SCC) is one of the leading causes of cancer mortality worldwide. It is generally thought that adjuvant chemotherapy provides modest prolongation of survival in various carcinoma. Docetaxel (Taxotere, TXT) play a significant role in the treatment of various solid tumors of epithelial origin. CsA (immunosuppressive drug) was widely used as adjunct for the treatment of cancer. Thus, it is important to pursue the apoptosis of IHOK and oral SCC induced by TXT combined with CsA related to the pathogenesis of oral SCC. But TXT combined CsA effect on IHOK and oral SCC remains unclear. After cultured IHOK and HN 22 oral squamous cell carcinoma cell line treated by 10 nM TXT and 1 μM, and caspase inhobitor, respectively, apoptosis index, cytochrome c and caspase-3 -8, -9 mRNA expression by RT-PCR, and procaspase-3 protein amount by immunoslot blotting was prepared. The purpose of this study were to examine the TXT-induced apoptosis pathway via caspase activation by CsA enhancement, and to apply these results to an effective therapeutic treatment plan for oral SCC by TXT combined CsA . 10 nM TXT showed about 60%, 55% celluar apoptosis of IHOK and HN 22, cell line, respectively, while CsA alone did not induce apoptosis in IHOK and HN 22 cell line. 1 μM CsA combined with 10 nM TXT increased apoptosis in IHOK and HN 22 cell line through caspase-3 and cytochrome c mRNA expression, while could not effect on caspase-8 and -9. Caspase inhibitor suppressed apoptosis of IHOK and HN 22 cell line induced by a combination of 1 μM CsA and 10 nM TXT. Immnoslot blotting showed procaspase-3 activation by a combination 1 μM CsA and 10 nM TXT, while caspase inhibitor inhibited activation. It suggested that a combination of CsA and TXT might induce increased apoptosis of IHOK and HN 22 oral squamous cell carcinoma cell line through caspase-3 activation. This treatment with a combination of TXT and CsA may be an effective therapeutic strategy for oral squamous cell carcinoma

This study was conducted to determine the influence of culture conditions such as temperature, time, water content, koji-thickness and agitation on the production of organic acid by Rhizopus sp. ZB9 isolated from Korean Nuruk during the preparation of rice koji, which is used in brewing the Korean rice wines, Takju and Yakju. Rice koji was made under different culture conditions, and the acidity of each koji was tested. The temperature range suitable for the production of organic acid was 28~32℃, and 36~48 hours of cultivation at that temperature range seemed to produce the optimum results. The production of organic acid increased in proportion to the increase in water content of steamed rice from 25% to 60%. An increase in koji-thickness induced no adverse effects on the production of organic acid, and agitation-work during cultivation showed very beneficial effects.
토마토 펄라이트 자루재배에서 기존에 알려진 배액 전극제어법 적용시기를 가능한 앞당기고, 배양액을 절감하기 위해 수행되었다. 실험처리는 정식후 15일차(T-15), 19일차(T-19), 22일차(T-22)에 배액전극제어법을 적용하는 3개 처리와 타이머법 1개 처리를 실시하였다. 기존의 정식후 1개월 이후에 배액전극제어법 적용하는 관행보다 2주 앞당긴 15일차 처리부터 작물이 배액전극제어법에 반응하는 것으로 나타났다. 생장 및 수확량은 배액전극법에서 높았다. 용수이용효율과 비료이용효율은 T-15 처리에서 가장 경제적이었고, 타이머법 처리는 경제성이 낮았다. 따라서 배액전극제어법 처리시기를 빨리 적용할수록 경제성이 높음을 알 수 있었다.
When radiation is irradiated onto biological tissue, the occurrence of biological change has been already demonstrated and the change of blood composition and chromosome abnormality could be suggested as the representative biological markers which can identify the disturbance caused by radiation exposure. Recently, radiation treatment is performed for the treatment of cancer. Since the protection of blood within normal tissue is very important, the development of radioprotective has been made continuously to protect normal tissues. Squalene is a very important precursor in the biosynthesis of cholesterol. It is the hydrocarbon contained in the liver of deep sea sharks and in olive oils, and large quantity of it is contained in skin, abdominal fat tissue, subcutaneous fat tissue, lymphatic gland, pancreas and in heart muscle. Because of 6 double bonds in SQ, it could easily bind with oxygen ions to have the hazardous oxygen removal capacity along with the effects of scar treatment, blood vessel expansion, inhibitory action of arteriosclerosis, and has been reported to have the effects on myocardial infarction and liver disease, treatment for burn. It has been reported to have active effect of fibroblast. Therefore, the current study was conducted to know the change of total protein, albumin, total cholesterol and glucose in serum after the injection of whole body radiation of SQ in mouse.
