Hyposexuality after stroke has been frequently observed, but hypersexuality as a sequela of stroke has not been commonly documented. We report a patient who exhibited hypersexuality and obsessive-compulsive behaviors after stroke in the region of the left mesial frontal cortex and both basal ganglia. At 2 months after stroke, he visited psychiatric unit due to these symptoms. His motor function was almost full recovered. He was treated with fluvoxamine and perphenazine. With two-month medication, his hypersexuality and obsessive-compulsive behavior disappeared. This case may indicate that basal ganglia-thalamocortical circuit plays an important role in the mediation of sexual behavior and obsessive-compulsive behavior. Since changes in sexual activity may not be spontaneously reported, a systemic inquiry into patient's sexual functioning after infarction in frontal lobe or basal ganglia is warranted.

Between January, 1991 and May 1995, mitral valve repair was undertaken on 32 patients under 15 years for congenital mitral regurgitation. Mean age was 24.0$\pm$26.1 months(range 3 months to 15 years), 16 patients were male and 16 patients were female associated cardiac anomalies were found in 26 patients (81%), and ventricular septal defects were noted in 18 patients(56%). In regards to pathologic findings, there were annular dilatation(n:7), leaflet prolapse(n=18), cleft leaflet(n=5) and restricted valve motion (n=2). The method of repair consisted of annuloplasty(Modif ed Devega type) in 14, repair of redundunt leaflet in 6, closure of cleft in 5, triangular resection in 2 and splitting of papillary muscle in one. There was no operative mortality and two late deaths occurred as a result of heart failure and sepsis. Tro patients required replacement of the mitral valve after 3 months and 7 months respectivehy because of recurrent mitral regurgitation. Actuarial survival was 92.5% at 46 months and actuarial freedom from reoperation was 95% at 12 months and 92.5% at 46 months. Actuarial freedom from valve repair failure was 68% at 12 months and 61.8% at 46 months. Although valve repair failure rate was high, we believe that mitral valve repair should be of rcrred to children because of low mortality and low reoperation rate.

뇌성마비는 뇌 발달시기중 초기의 장애로 인하여 운동기능과 자세의 이상 등을 초래하는 질환으로 임상적으로 여러 유형으로 나누어진다. 뇌성마비 환자중에서 MRI 상 롤란도야의 이상소견을 보이는 경우 특이한 임상적 특징을 나타낸다고 보고되어있다. 본 논문에서는 이들을 대상으로 하여 뇌 단일광자컴퓨터촬영에서 나타나는 뇌혈류 이상 소견과 MRI 소견, 그리고 임상양상들을 비교해보고자 하였다. 임상적으로 뇌성마비로 진단된 80여명의 환자중 MRI상 롤란도야에 저산소성 뇌질환의 소견을 보인 7명을 대상으로 하였다. 이들에게 5-10mCi의 Tc-99m-ECD를 정맥주사후 뇌 단일광자컴퓨터촬영을 하였다. 뇌 단일광자컴퓨터촬영상에서는 특히 뇌피질, 선조체, 시상, 뇌간 및 소뇌의 혈류이상 소견을 분석하였고, 이를 MRI 소견 및 임상증상과 비교하였다. 모든 환자들은 만삭 또는 만삭에 가깝게 태어났고, 주산기 아사가 여섯명의 환자에서 있었다. 임상적으로는 긴장성 사지마비로 나타났다. Tc-99m ECD를 이용한 뇌 단일광자 컴퓨터촬영상 롤란도야의 혈류감소는 모두에서 확연하게 나타났다 MRI상에서 롤란도야의 이상소견은 5명에서는 확실하게 나타났고, 2명에서는 의심되었다. MRI상에서 이상소견을 보인 것보다 더 광범위한 부분에서 뇌단일광자컴퓨터촬영상 이상소견이 보였다. 결론적으로, 롤란도야에서 이상소견을 보인 환자는 임상적, 구조적, 그리고 기능적으로 특이한 소견을 보였다. Tc-99m-ECD를 이용한 뇌 단일광자컴퓨터촬영은 매우 민감하게 반영하였고, MRI보다 뇌의 더 광범위한 부위에서 이상소견을 보였다.

Backgrounds and Objects: Carcinoma of the tongue is the most common cancer of the oral cavity. A primary treatment strategy includes surgery and/or radiotherapy. Resection of the tongue often results in speech dysfunction, which depends on the site and extent of resection, type of reconstruction, and the mobility of remaining tongue. This study aimed to evaluate the characteristics of articulation errors that were resulted from the partial glossectomy without free flap reconstruction. Materials & Method : Articulation evaluations including speech intelligibility and percent of correct consonants (PCC) were performed for 24 patients who underwent partial glossectomy for their T1 or T2 tongue cancer. Mobility of the tongue, size of the resected tongue, and the history of adjuvant radiotherapy were analyzed for their relationship with the results of articulation evaluation. Results: Speech intelligibility score was $6.4{\pm}0.9$ (on 7-point scale) and overall PCC was 96.9%. There were close relationships between the size of resection and limitations in the tongue mobility, especially in "protrusion and elevation (r=-0.687)" and "retroflexion (r=-0.775)". Errors in "alveolar fricatives" and "palatal affricates" were also closely related with the size of resection (r=-0.537 and -0.538, respectively). PCC for "liquid sound" /r/ was 83.2%, which was closely related with the history of radiation therapy. Conclusion : Overall articulatory function was satisfactory in cases of early tongue cancer after partial glossectomy of a limited volume without flap reconstruction. However, the size of resection and the history of radiation therapy were closely related to the limitations in some types of tongue mobility and the resultant articulation errors.

Purpose: The purpose of the study was to investigate the difference of health behavior modification between male and female patients with cardiovascular disease; and to compare the predictors of health behavior between the male and female subjects. Methods: A comparative study design was used in the study. A total of 228 patients(male 114, female 114) with cardiovascular disease were recruited from outpatients clinics in 2 university hospitals in Korea. Data were analyzed using t-test, $X^2$, ANOVA, ANCOVA, Pearson correlation, and multiple regression with SPSS 20.0. Results: There was significant difference of health behavior between male and female patients with cardiovascular disease (F=9.45, p=0.002). The significant predictors of health behavior among male subjects were self-efficacy, perceived barriers, perceived susceptibility, medical support and autonomous motivation, accounting for 45%; the significant predictors of health behavior among female subjects were self-efficacy, medical support and autonomous motivation, accounting for 51%. Conclusions: It is suggested to take different health promotions strategies to maintain the performance of health behaviors among male and female patients with cardiovascular diseases.

Purpose : The purpose of this study was to compare the effects of Joing Mobilization and Group back Pain Exercise Program on the disability level and the pain of flexibility and the back muscle strength in the hearing impairment patients with Low back pain. Methods : The subjects of this study were 12 patients, 8 males and females. They visited clinic for physical treatment within 6 months after onset of low back pain. One group was applied with Joing Mobilization and other group was with Group back Pain Exercise Program. The patient were treated special program 3 times session weekly. And treatment 2 times session was 15min with physiotherapy weekly. The muscle strength was measured by Cybex 660, the level of disability by Oswestry low back pain disability scale, the intensity of pain by visual analogue scale (VAS). The data was analysed by paired T-test and independent T-test. Results : The results of this study were summarized as follow : 1. The Oswestry disability score of experimental and control group were significantly decreased and there was no difference in the Oswestry disability score change between joint mobilization group and back pain exercise group. 2. The pains in anterior, postrior, lift lateral and right lateral bending and in rotation of back pain exercise group were significantly increased compared with those of joint mobilization group. 3. The flexors and extensors peak torque of back pain exercise group were significantly increased at test velocities $30^{\circ}$/sec, $60^{\circ}$/sec compared with those of the joint mobilization group. There was no significant difference in extensors and flexors peak torque at $30^{\circ}$/sec, $60^{\circ}$/sec between two group. The results showed that the back pain exercise group were effective in decreasing disability score and pain of trunk activity, increasing trunk extension and flexion peak torque. Conclusion : It is suggested theat the back pain exercise program could be an essential factor for the effective intervension to the hearing impairment patients suffere from low back pain.

최근 선진국가들에서는 전자파 장애 증후군에 관심이 집중되고 있는데, 전자파에 장기 노출 되는 인구에서 뇌암이나 유방암, 백혈병 등의 발생률이 높다는 보고(Kolmodin-Hedman 등, 1988 ; Demers등, 1991)가 있어서 전자제품의 생산업체는 물론이고 사용자에 대해서도 불안한 관심사가 되 어 있다. 전자파가 생체에 미치는 영향은 열적 효과와 비열적 효과에 의한 것으로 구분된다. Microwave는 약 300MHz에서 300GHz 사이(파장 1m에서 1mm사이)의 주파수를 가지는 전자파로서 이온의 운동이나 쌍극자분자(dipole molecule)들을 진동시키므로서 조직에 열이 발생한다. 열이 과도하게 발생하면 세포 단백질이 응고하게 되는 등 일반적으로 생각할 수 있는 고열로 인한 여러 가지 유해환경이 조직 에 조성될 수 있다. 실제로 고전압의 전자파에 노출된 안구의 수정체에 백내장 등의 병변이 발생한 것 으로 보고된 바 있다(Adey,1981). 일반적으로 전자파의 생체에 대한 작용으로는 이렇듯 조직에 흡수 되는 전자파의 에너지에 의한 열작용이 지배적인 것으로 생각되어 왔다. 그러나 초저주파역대(Extre- mely low frequency, EMF)의 변조 및 펄스파 등의 영향에 관해서도 조직의 온도상승으로는 설명할 수 없는 현상이 보고된 바 있다. 이러한 비열적 효과가 신경계에 끼치는 영향에 대해서는 혈액뇌관문 의 투과성 변화(Oscar와 Hawkins, 1977), 뇌종양 발생, 칼슘대사 이상 및 신경전달물질에 대한 영향 등이 주장(Anderson, 1993)되고 있으나 아직 그 분명한 기전이 밝혀져 있지 않은 상태이다. 또한 그 영향의 평가에 서도 일정한 기준이나 지표가 정해지지 않은 실정이다. 그러므로 신경계에 대한 대체적인 소개와 더불어 전자기파의 영향에 대한 이제까지의 보고를 종합 하고 향후 연구의 방향을 소개하고자 한다.> 이온이 공동 첨가제로 더 적합하다.u(30 .angs. )/CoFe(35 .angs. )/NiO(800 .angs. ) 구조를 갖는 spin-valve 박막은 극대 MR비 6.3%, 유효자기장감응도 약 0.5(%/Oe)를 보여 spin-valve head 재료로 적합함을 알 수 있었다.다.다.다.는 각각 148 meV .angs. $^{2}$, 103.8 meV .angs. $^{2}$와 1.77 * $10^{-6}$ erg/cm, 0.67 * $10^{-6}$ erg/cm 였다.다.자 노인들을 영주권자와 귀화 시민권자의 구분없이 하나의 집단으로 간주하고 분석해 왔던 것을 볼 때, 앞으로의 연구는 이론적으로나 방법론적으로 시민권의 유무가 주거형태에 끼치는 영향도 함께 고려해야 할 것이다.에 나타난 인도의 영향은 여성복식과 남성복식에 있어서 서로 유사점과 차이점이 보이는데, 인도의 영향이 여성복식에 있어서 그 빈도가 더 높고, 종류가 더 다양함을 볼 수 있다. 여성복식에 있어서는 12가지의 다양한 인도복식스타일이 나타났으며, 그중 가장 많이 보이는 스타일은 Indian Shirt/Blouse/Smock/ Dress이며, 그 뒤를 이어 Madras, Indian lowery등을 볼 수 있다. 남성복식애 나타난 7가지의 스타일 중에는 Madras가 가장 빈도가 높으며 그외의 스타일들은 그 빈도가 매우 낮음을 볼 수 있다. 인도의 영향의 정도 (Attribution Categories) 있어서는 여성과 남성복식 모두에 있어서 인도에서 직접 수입된(originated) item이 각각 전체의 90%와 81%를 차지하여, 인도복식의 영향은 받았으나 미국내에서 제작된(attributed and connotated) item 보다 휠씬 더 많은 수를 보였다. 인도복식스타일이 가장

Purpose: To analyze the postoperative functional and radiographic follow-up results in patients who underwent percutaneous radiofrequency ablation therapy after the diagnosis of osteoid osteoma. Materials and Methods: Seven patients, who were clinically and radiographically diagnosed with osteoid osteoma from July 1999 to January 2001, and received percutaneous radiofrequency ablation therapy. The average follow-up period was 15.5 months(range, 8~25 months). For the diagnosis and accurate localization of the lesion, simple radiography, computed tomography and magnetic resonance imaging(MRI) were performed preoperatively. Simple radiographs and MRI were taken periodically for the follow-up studies. Results: In all 7 patients, symptoms completely disappeared within 3 days after the operation. The average period of hospitalization was 2.4 days, excluding 1 patient who needed an additional burn treatment. The average postoperative night and day pain scores were 1.8 and 1.3, respectively. The average vocational and recreational activity scores were 1 and 0.6, respectively. Conclusions: Satisfactory functional results were obtained with percutaneous radiofrequency ablation therapy for the elimination of osteoid osteoma. Compared to conventional treatment, the advantages of this therapy were short hospitalization period, no internal fixation and bone graft for preventing fracture, and no limitation of joint motion by long fixation period.

Safety is one of the key issue in the regulation of cosmetics. Cosmetic Act deals with it in Korea. The guidance for the testing cosmetic ingredients and their safety evaluation are prepared by Korea Food and Drug Administration. Ultraviolet radiation could Induce skin damage, edema, erythema, photoaging, immune dysfunction and skin cancer. Ultraviolet radiation is classified as Group 2A(probably carcinogenic to humans) by International Agenry for Reaserch on Cancer(IARC). The in vitro methodologies for evaluating the toxic potential of ingredients reported in the literature have not yet been sufficiently validated for use in areas other than the study for mutagenicity/genotoxicity, for pre-screening for severe irritancy, for screening of phototoxicity and for evaluating the percutaneous absorption. The 3T3 neutral red uptake photoxicity test (3T3 NRU PT) was accepted as OECD toxicity guideline in 2002. The 3T3 NRU PT is an in vitro method based on a comparison of the cytotoxicitv of a chemical when tested in the presence and in the absence of exposure to a non-cytotoxic dose of UVA/visible light.

Delirium is an organic psychiatric syndrome characterized by an acute onset, prominent disturbance of consciousness and cognitive impairment with fluctuating course. Although there is not a clear consensus concerning the optimal classification system for delirium subtypes, Lipowski(1983) firstly classified delirium by psychomotor activity, namely hyperactive, hypoactive, and mixed. According results of several following studies, prevalence of hypoactive delirium were not less than that of hyperactive delirium. But a diagnosis of hypoactive delirium often missed, which is most frequently misdiagnosed as depression and dementia. Hyperactive delirium can be caused by alcohol or benzodiazepine withdrawal, would be related with excessive dopamine and cholinergic deficiency, and is more responsive to high-potency antipsychotics therapy. Hypoactive delirium would be caused by metabolic encephalopathy, and tends to present a less responsiveness to antipsychotics and poorer overall prognosis with a prolonged duration of admission than hyperactive delirium. Delirium is not a homogenous syndrome. Because of different subtypes, it may have dissimilar underlying pathogenetic pathways. So different treatment strategies between various subtypes may be needed.
