Purpose: This study was conducted to evaluate the changes in neuropsychological functioning in patients with temporal lobe epilepsy (TLE) after temporal lobe resection. Methods: Fifty-four TLE patients were evaluated before and after surgery using comprehensive neuropsychological tests to assess general intelligence, executive functioning, language, verbal and visual memory, working memory, visuo-spatial ability, attention and motor function. Results: The patients with left TLE showed no impairment of neuropsychological functioning after surgery, with the exception of auditory immediate memory. Furthermore, they showed significant improvement in performance IQ, executive function, working memory, visual memory, attention and psychomotor speed. The patients with right TLE did not show any significant impairment in post-operative neuropsychological functioning. They showed improvements in intellectual and executive functions, language, visual memory, visuo-spatial ability, attention and motor function post-operatively. The patients with hippocampal sclerosis showed greater post-operative improvements than the patients without hippocampal sclerosis regardless of the side. Patients with better pre-operative neuropsychological function had a higher chance of successfully discontinuing all seizure medications after surgery. Discussion: The results of this study suggest that temporal lobectomy does not harm the neuropsychological functioning of patients with intractable TLE and that it improves cognitive functions of the contralateral hemisphere.

ObjectiveAlthough several self-report versions of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) have been developed and used widely, few psychometric studies have established the construct validity of this measure. Therefore, we developed Korean self-report version of the Y-BOCS and evaluated its factor structure, reliability, and validity.MethodsA non-clinical student sample (n=206) and a clinical OCD sample (n=199) completed the Korean self-report version and other measures of obsessive-compulsive disorder (OCD), depression, and anxiety.ResultsConsistent with the originally proposed structure, confirmatory factor analyses supported a factor structure comprised of Obsessions and Compulsions factors in the Korean self-report version. Two subscale scores and the total score of the Korean self-report version showed good internal consistency and convergent validity, but relatively poor discriminant validity. Applying a cutoff score of 16, 84% of OCD patients and 93% of the non-clinical sample were classified correctly.ConclusionKorean self-report version of the Y-BOCS is a psychometrically sound and valid measure for assessing OCD symptoms as compared with the clinician-administered version. The originally proposed division of OCD severity into obsessions and compulsions appears accurate in the Korean self-report version. The cutoff score for the Korean self-report version needs adjustment based on further researches.

We report here (CmCn)-P-Pt thin films with the coercivity higher than 2600 Oe at the thickness of 180 A (hir e t value of 0.9 memdcm') even when they were deposited without substrate heating and bias voltage. The effects of the fiim composition and the magnetic layer thickness were studied. The coercivity of CO-Cr-Pt film increased with addition of P up to 12 at.%. With addition of P, the degree of CO (OOO2) texture was reduced and the grain size of fiims became more uniform. These effects appear to be associated with the coercivity increase. I . INTRODUCTIONDevelopment of high coercivity media at very thin thickness is essential for the ultra high density recording as suggested by Murdock[ll and YogiL21. For this purpose, many processing methods and various temary and quatemary alloy systems have been developed, for example, Co-Cr-Pt-Si[S], Co-Cr-Pt-B[41, Co-Cr-Pt-Ta This article reports a new alloy system of (CO-Cr)-P-Pt with high coercivity of 2600 Oe or higher even when deposited without substrate heating and bias voltage. Our previous work[71 showed that the coercivity increased with addition of P up to 12 at.% in the CO-P or CO-P-Cr films and the optimum Cr content was 6 at.% in the ternary system. In this paper, the variation of coercivity with composition in the (GmCr/)-P-Pt pseudo-ternary system was extensively studied. We also discuss the origin of high coercivity in this alloy system 11. EXPERIMENTAL PROCEDURE Samples were prepared by using DC magnetron sputtering on circumferentially textured Ni-P/Al substrates and non-textured glasses. Film composition was varied by changing the number of Co4P3 and Pt chips placed on CO-7 at.%Cr target.The base pressure was below 5 X Torr and Ar pressure during sputtering was 10 mTorr. The substrate temperature was room temperature or 260 *c.The compositions of magnetic layers were determined by wavelength dispersive spectroscopy. The magnetic properties were measured by a vibrating sample magnetometer. The crystalline structures were analysed by XRD using the films sputtered on glass substrates. The surface morphologies of the films were observed by using atomic force microscopy(AFM). The corrosion resistance of the films containing different P andor Pt contents was investigated by counting the number of pits in the SEM photographs of the samples. The samples were prepared by putting the films into a chamber maintained at the constant temperature of 80 "c and at the constant humidity of 80 % for two weeks. Fig. 1 shows coercivity contour diagram of (Co-Cr)-P-Pt pseudo-temary films deposited on textured Ni-P/Al substrates at room temperature. RESULTS AND DISCUSSION

Vector moving Preisach model was applied to the untextured Co thin film media. The out-of-plane easy axis distribution of the particles was derived directly from the texture coefficient phkl obtained from x-ray diffraction analysis, which corresponds to the fraction of the grains that have {hkl} plane lying parallel to in-plane direction. In order to validate this variable, angular dependence of magnetic properties of CoCrPPt/Cr/glass thin films with two different composition was measured by using a vibrating-sample magnetometer. Simulated results showed little difference from the measured data.
