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.

The cause of Parkinson's disease (PD) is largely unknown. However, free radical toxicit? may plaf a role ip. the degeneration of substantia nigra, which is the Hajorfocus of pathological damages in PD. Recently, a neuroprotective effect of nicotine in PD has been suggested. Therefore, the mechanism of neurodegenerafion and protective potential o( nicotine in PD were investigated in the experimental modeB of Pll using a neurotoxin, C57BL/6mice were administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg,j.p.). The degree of neurodegenerafion was determined by immunohistochemical stainiHB oftyrosine hydroxylase (TH). TH-positive cells on nigral sections were found 56.0 ±4, 57.9 ±6,52.315ce11s, 49.0±3cells, and 39,4±Scells at days 1, 2, 3, 4, 5, respectively (controls : 57.6±Scells). Hoechst and TUNEL staining showed no evidence of apoptosis. The exandnation on themice co-adrunistered with nicotine(0.2mgAg) and MPTP(30mgag) revealed a tendency ofnicotine protective effects. At days 4 and 5, the degree of TH-positive cells was decreased by20-30%, In corclusiffn, the role of apoptosis was not evidenced in this MPTP modeB of PB.The possible proteccon by nicotine should be elucidated with further studies.

This study was conducted to extract the multivariate discriminant function of the KWIS and MMPI in 141 male patients with unilateral cerebral dysfunction. They were referred to for neuropsychological examination, consisted of 70 unilateral left and 70 unilateral right cerebral damage patients. The results were as follows ; The study 1 : The discriminant function of the KWIS and MMPI between cerebral damage and neurotic groups were extracted by each of two group characteristics in the discriminant variables. f(x)=.080(V)+.272(Dsy)-.015(Hs)+.054(D)+.042(Pd)-.028(Si)-2.363 The results of discriminant function analysis were : the corrected predictly percentage for the cerebral damage patients and neurotic patients were 79.9% and 72.0%. The study 2 : The discriminant function of the KWIS and MMPI between unilateral left and right cerebral damage groups were extracted by each of two group characteristics in the discriminant variables. f(x)=.262(C)-.092(A)+.271(Ds)-.102(PA)-.127(OA)+.065(D)-.028(Hy)-.038(Pa)+.029(Ma)-.026(Si)-.020(L)+.157 The results of discriminant function analysis were : the corrected predictly percentage for the unilaterl left cerebral damage patient and right cerebral damage patient were 67.1% and 71.6%. The results suggested that above two discriminant functions have a considerable discriminant power.

최근 흡연을 시작한 젊은 성언에서 급성 호산구성 폐렴의 발생에 대한 증례가 보고되고 있다. 급성 호산구성 폐렴은 대개 발열을 동반하기 때문에 초기에는 감염성 폐렴으로 잘못 진단, 치료되는 경우가 많다. 아직 정확한 병태 생리 및 조직학적 소견은 밝혀져 있지 않지만 병력 청취 및 임상 양상, 방사선 소견의 관찰을 통해 급성 호산구성 폐렴을 의심하고, 진단을 위해 기관지 폐포 세척액 검사를 시행한다면 좀 더 쉽게 진단 내릴 수 있을 것이다. 본 저자들은 최근 처음 시작한 흡연에 의해 발생한 급성 호산구성 폐렴을 진단하고, 스테로이드를 투여하여 성공적으로 치료한 환자 2예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Acute eosinophilic pneumonia(AEP) is characterized by acute febrile respiratory illness associated with diffuse pulmonary infiltration and pulmonary eosinophilia. The specific etiology for acute eosinophilic pneumonia is elusive. By some investigators, cigarette smoking is suggested as a causative substance which can cause AEP. In recent, the authors experienced two cases of AEP following cigarette smoking. Both cases had characteristic features including age around 20 years, new onset smoking before occurance of AEP, diffuse infiltration on chest radiography, pulmonary eosinophilia based on bronchoalveolar lavage and acute improvement after steroid therapy. These clinical features are resemble with previous smoking induced AEP case reports. Base on these clinical features, cigarette smoking associated AEP could be diagnosed more easily.
