Objectives : This study was conducted to evaluate the reliability and the validity of the Korean version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K). Methods : The subjects were 55 schizophrenic patients between ages of 26 and 58 who were recruited from the psychiatric unit of the university hospital and the out-patient clinic. The SUMD-K and insight scale of PANSS were applied to the patients. Results : The range of inter-rater (Spearman's rho) of the general items of SUMD-K were .97-.98 on the current illness and .58-.98 on the past illness. The correlation coefficient between the sum and the general items of the SUMD-K showed high scores. The concurrent validity between SUMD-K and insight item of PANSS was high (scores between .59-.96). However,the reliability and the validity of the attribution items of symptoms showed low scores compared to the current symptoms. Conclusion : The SUMD-K was confirmed in its reliability and validity. It can be a useful clinician-rating scale for evaluating insight in schizophrenic patients as well as patients with other neuropsychiatric conditions.

宋埈泰,李鍾德 成均館大學校 科學技術硏究所 1994 論文集 Vol.45 No.1

In this study, the design of Acoustic Sapphire Lens for SAM is described. Also, We are designed directly Acoustic Sapphire Lens for 100MHz acoustic, pulse. The acoustic focus beam can be readily realized by Acoustic Sapphire Lens with a cylindrical concave surface. The design criteria of Acoustic Sapphire Lens include the following three points. (1) effective use of acoustic field distribution in the Fresnel region to determine Acoustic Sapphire Lens' length. (2) suppression of spurious signals caused by the internal reflections in the Sapphire, and Sufficient distance for the Sapphire without overlapping a information signal. (3) spherical aberration and acoustic attenuation of water are considered suitable. Here, Acoustic Sapphire Len's demensions which used in acoustic pulse 100MHz were obtained as following conclusion. Aperture angle θ=45°, Aperture radius R=1.13mm, Focal length f=1.31mm, Sapphire length 1=18mm.

This study was carried out to identify the effects of seaweed extracts(GA14) on growth of two rice cultivars, Junambyo and Donganbyo. Seedling qualities of two cultivars were better in all items including heading dates at early stage treated at seedling plus 2-3 leaf stages than at single treatment of seedling. Ripening ratio of Junambyo in paddy field was increased 0.3% by seaweed extracts(GA14) treatment, but that of Donganbyo decreased 0.5%. 1,000 grain weight of Junambyo and Donanbyo by seaweed extracts(GA14) treatment was two to four grams higher and the yield of two cultivars was also higher by three to four percent. Appearance characters of two rice cultivars was high in head, while damaged, chalky and crack rate were low at seaweed extracts(GA14) treatment. Protein, moisture and amylose characteristics related to table quality of Junambyo were not different by seaweed extracts treatment, but table values was high in only treatment. Donganbyo was also similar to Junambyo, but table quality was slightly high at non-treatment.

The thickness -extensional trapped energy mode vibrations are treated analytically. In each program the solution cinsists of a sum the dominant plate eigensolutions for shoted electrodes in the electroded resgion and for zero surface charge in the unelectroded region. The driven thickness solution is also included in the electroded region in the programs of forced vibrations. Combinations of these solutions for the infinite plate, which satisfy the differance equations and boundary conditions on the major surfaces exactry, are then employed in an appropriate variational principle of the linear piezoelectricity in order to satisfy the remaining boundary conditions at the junction between the electroded and unelectroded regions approximately.

In order to utilize the ubiquitous sensor network technology, it is necessary to identify the communication characteristics of the sensor node. The purpose of this study is to investigate the wireless performance to be related the environment (i.e. humidity) which can cause data loss in the greenhouse environment. The performance of wireless communication was conducted in the constant temperature and humidity device. The results of performance for Zigbee communication were not affected by the humidity. The Zigbee communication without the data loss would be more effective to control the environment in the greenhouse.

Euonymus alatus추출물의 실험적 당뇨발생 억제효과

김태중,송희종,소준노,이정호 大韓免疫學會 1996 大韓免疫學會誌 Vol.18 No.4

Insulin-dependent diabetes mellitus (IDDM) is majorly caused by an immune system-mediated destruction of the beta cells in the islets of Langerhans. Patients with IDDM face major changes in lifestyle and the possibility of debilitating and life-threatening complications. In Korean traditional medicine, Euonymus alatus (EA) extract has been widely used for preventing and curing ulcer and inflammation. A previous study has shown that EA itself has an antidotic activities against inflammation, suggesting possibility that EA can exert this beneficial effects to IDDM by an initial protection against diabetes caused by pancreatic inflammation. The present study was undertaken to evaluate the prophylactic effect of EA extract on the diabetogenesis of streptozotocin (STZ) and alloxan (ALX), using animal model, and to explore the possible mechanisms of its antidiabetic activity. Multiple low doses of STZ (45 mg/Kg for 5 days) in ICR mice and single dose of ALX (60 mg/Kg) in SD rats induced high level of hyperglycemia (defined as plasma glucose level > 300 mg/dl) and remarkably diminished body weight. But, animals that received diabetogenic agents in combination withsEA were maintained plasma glucose level as a normal state ( < 150 mg/dl), and appeared in good health and had similar weights to those of normal control. These results strongly indicated that EA prevented and blocked diabetogenesis of chemicals. EA significantly inhibited the nitric oxide- and tumor necrosis factor-production of mouse peritoneal macrophages. However, EA enhanced interleukin 1 production of macrophages at lower concentration but not at higher. EA itself increased phagocytic activity of unstimulated monocytes, but it did completely block that activity of zymosan- or platelet activating factor-stimulated cells. Taken together, this study led to conclusion that EA itself has a significant prophylactic effects against diabetes, and also suggested that its antidiabetic effects might be manifested by the downregulation of inflammatory process in diabetogenesis.

Objectives: This study was produced to examine the effects of moxibustion that had been played important role to traditional oriental medical treatment on disease. Recently, it was reported that moxi-tar which is generated in the process of moxibustion as burning combustibles decreased nitric oxide(NO) and inducible NO synthase (iNOS) generation in cellular experiments. Methods: Carrageenan-induced arthritis rat model was used to test the effect of moxi-tar as a chronic pain model. Diluted moxi-tar was single injected in several acupoints or combined with electroacupuncture (1 ms, 2 Hz, and 2 mA) into contralateral ST36 acupoint for 30 min to assess the synergic effects. After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 12 hours. Endogenous NO and iNOS, cyclooxygenase-2 (COX-2), and c-Fos protein expression in the spinal cord were examined on a rat model of carrageenan-induced arthritis. Results : After the induction of arthritis, rats subsequently showed a reduced stepping force of the affected limb for at least the next 4 days. The reduced stepping force of the limb was presumably due to a painful knee, since oral injection of indomethacin produced temporary improvement of weight bearing. Moxi-tar produced significant improvement of stepping force of the hindlimb affected by the arthritis lasting at least 9 hours. The magnitude of this improvement was equivalent to that obtained after an oral injection of 3 mg/kg of indomethacin and this improvement of stepping force was interpreted as an analgesic effect. Moxi-tar produced the improvement of stepping force of the affected hindlimb in a dose-dependent manner. Both NO production and iNOS, COX-2 protein expression increased by arthritis were suppressed by moxi-tar. Moxi-tar on combination with electroacupuncture (EA) produced more powerful and longer lasting improvement of stepping force of the hindlimb affected by the arthritis than either moxi-tar or EA did. Conclusion : The present study suggest that moxi-tar produces a potent analgesic effect on the chronic knee arthritis pain model in the rat and that moxi-tar-induced analgesia modulate endogenous NO through the suppression of iNOS/COX-2 protein expression.
