Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

The Resolver usually used in industry is the absolute angle analog sensor that must be in order driving BLDC (brushless DC) motor, and it needs RDC(Resolver-to-Digital converter) for changing the output signal to digital to be applied to the SVPWM(Space Vector Pulse Width Modulation) algorithm. Commonly used S/W RDC needs trigonometric function. What it takes a lot of calculation time of processor is gotten at weak point. In this paper, S/W RDC is realized except trigonometric functions as a result of feedback resolver outputs after filtering using FIR filter. thus, processing time is reduced. So. One-chip DSP Controller operating the Vector Control, RDC, and SVPWM can be designed.

Kallmann's syndrome is the most common form of isolated gonadotropin deficiency, characterized by hypogonadotropic hypogonadism due to GnRH deficiency, delayed puberty and smelling difficulty. It occurs sporadic or familial pattern, and the mode of inheritence has not been fully documented. The defect in patient of Kallmann's syndrome occurs at suprapituitary level involving mechanism that regulate GnRH synthesis or release, so this syndrome classified as a secondary hypogonadotropic hypogonadism. The gonadotropin or pulsatile GnRH administration enable successful stimulation of spermatogenesis and fertility. We have experienced 1 patient with Kallmann's syndrome and presented with the review of the literature.

Background and Objectives : COX-2, the inducible form of cyclooxygenase(COX), is upregulated in transformed cells and in malignant cells, which have important roles in promotion of colorectal carcinogenesis, invasiveness and angiogenesis. Vascular endothelial growth factor(VEGF) may act as endothelial cell mitogen in various cancer tissues. It will increase tumor growth and angiogenesis. Aims of this study were to asses COX-2/VEGF expression and it's clinical correlation in sinonasal tumors and to investigate the effects on angiogenesis also. Materials and Method : The study samples were obtained from surgical removal of 27 cases of inverted papilloma(IPs), 5 cases of IP with malignant transformation(IP-MT), 16 cases of Squamous cell carcinoma(SCC) in sinonasal cavity COX-2 and VEGF expressions were assessed by immunohistochemical staining. Synchronism of COX-2/VEGF expression in one tumor cell was demonstrated with double immunofluorescence technique. Results : The expression rates of COX-2 were 37% in IP, 80% in IP-MT and 100% in SCC. The positive rates of VEGF were 29 6% in IP, 100% in IP-MT and SCC. COX-2 and VEGF expressions were increased as tumor progressed, and there is a positive correlation between COX-2 &EGF expressions. All clinical features which were compared are not associated with COX-2 &EGF expressions except malignant change in IP(p=0 028). Synchronism of COX-2/VEGF expressions was noted in all positive immunostaining samples. Conclusion : These findings suggest the role of COX-2 pathway could be involved in sinonasal tumor angiogenesis, which is modulated by VEGF COX-2 may act as autocrine factor in VEGF expression. There is a potential role for selective COX-2 inhibitors in the treatment of these lesions.

Recently there has been interested in the use of natural dyes in textile applications. Generally natural dyes can exhibit better biodegradability and have a higher compatibility with the environment. In this study, cotton wool and silk fabrics were dyed with alkali extract of Arecae semen using various mordants, and their dyeabilities were discussed. Additionally the fastness to washing, perspiration, light, rubbing, and drycleaning and UV-B protection rate were also investigated. Cotton, silk and wool fabrics dyed with alkali extract of Arecae semen were colored in reddish yellow tint. The optimum dyeing condition of the colorants extracted from the Arecae semen was three repeated dyeing at 95℃ for 1.5hrs. The dyed fabrics by using mordanting methods improved the fastness to washing, perspiration and drycleaning, but the fastness to light and rubbing were not increased. The UV-B protection rate of the wool fabrics were increased by dyeing with extract of Arecae semen.

Herpes zoster is well known as an acute, self-limited disease of unilateral sensory dermatome caused by varicella-zoster virus and characterized by grouped vesicular skin eruption and pain over several dermatomes as well as single. This virus usually affects the thoracic dermatome and there are a few reports that this virus involves lower lumbar or sacral area, and recurrent cases. We experienced 2 cases that zoster virus involved L4 or S2 dermatome and left typical skin lesions, of which one was a recurrent case involving different dermatome at an interval of 8 years and the other was a rare case involving sacral dermatome.

A 63 year-old woman who had diagnosis of multiple sclerosis complaining left hemiparesis and fluctuating decreased visual acuity in her right eye and abnormal findings in pattern shift visual evoked potentials(PSVEPs) and on T2 weighted MR scanning. We treated her subcutaneously with 250μg interferon (3-lb(ITFß -lb) every other day. There were detected pancytopenia, skin rash, and abnormal liver function test seven days after the therapy. In spite of reducing the dose of interferon injection, abnormal laboratory findings were not returned to normal. Dose adjustment of interferon-I3 for body weight or race, may be helpful to reduce the side effects.

A failure mode in the beam strengthened with a high modulus plate appears as a interface debonding failure or ripping-off failure. This failure mode means that plate is separated from adhesive or concrete before displaying its own ability. Therefore, as a method for controlling a premature failure, it is need to use a general anchorage implement. We conducted bending tests for reinforced concrete beams strengthened with CFRP. The experimental variables were a concrete strength, reinforcement ratio, cover thickness of concrete and length ratio of CFRP for a pure span. A failure load, failure mode, load-deflection curve and strain response at different distances from a cut-off of CFRP and strain distribution curve were measured to determine the bond development length. Also, the bond development length was compared with Nguyen’s model and British Standard specification.

This paper presents a feasibility study of an alternative strengthening method by slot-bonded CFRP plates for reinforced concrete beam. A total 14 reinforced concrete beam were constructed, tested and the response of the beams in terms of deflection, strains, failure load and failure mode were examined. Each specimen was initially loaded for 75% of ultimate load, cracked specimen were strengthened with CFRP plate and then tested until complete failure. Test variables included the strengthening method, steel ratio and strengthening length, and the effects according to each test variables are analysed. The experimental results show that proposed methods can increase the flexural strength and stiffness of the beam significantly. Also, the failure of the specimens strengthened by the proposed method are more ductile than externally bonded specimen.
