Background: The recognition of prevention and early detection of skin cancer has been increased more than before. Although skin cancer is not rare, most patients are little known about general awareness of skin cancer. Objectives: In this study, we survey the awareness and knowledge of skin cancer and sun protection behavior among South-Gyeongnam province. Methods: We reviewed a written questionnaire and patients’ self-checked records including patients’ basic medical information and knowledge of skin cancer protective modalities. Results: In total 284 subjects (94.7%(284/300), 67%(190/284) females, mean age 57.4 years) completed the survey. Most people (77.5%, 220/284) knew that the sun was most dangerous for their skin but relatively large portion of them (42.7%, 94/220) had no action to protective attitude like sun screen, large hat and gloves. Conclusion: The results show that many participants had known necessity of skin cancer prevention and importance of early detection, but didn’t have had any protective action. Therefore, a more effective skin cancer education and prevention program is needed. We suggest that the measurement of effects of a multimodal educational intervention on knowledge of sun protection practices and engagement in self sun-protection behaviors also need to be check.
[P509] Lichen planus pigmentosus presenting with flexural area

Lichen planus pigmentosus (LPP) is an uncommon variant of lichen planus that tends to occur in middle-aged individuals with darker pigmented skin. Clinical findings include hyperpigmented, brown to gray-brown macules and patches on sun-exposed areas and, in the rare inversus variant, on the flexural areas and intertriginous zones. The pattern of pigmentation is generally diffuse, although follicular, reticular, and unilateral linear variants have been described. We recently encountered a rare case of LPP developed in flexural area, not in sun-exposed area. A 58-year-old male patient presented with brown macules on the inguinal area for 6 months. One or two dark brown macules first appeared and spread gradually. A physical examination showed multiple, ill-defined, dark brown macules on inguinal area. The dermoscopic finding showed mottled pattern and elevated margin. The incisional biopsy was performed and a diagnosis of LPP was made. The fact that LPP can develop in non-sun-exposed areas as well as sun-exposed ones requires a new hypothesis for the pathogenesis of LPP.
DirectX 기반 다채널 영상 감시 시스템 구현 및 성능분석

Multichannel visual monitoring systems such as DVR (Digital video Recording System)s have to process video data steams which are characterized by their large volume of data and their continuous time properties. Thus, multichannel visual monitoring systems may not show satisfactory performances in display, recording, retrieval and playback of video data if one does not design the architecture of S/W precessing of video data streams efficiently. Microsoft Windows environments provide DirectX for efficent processing of multimedia streams. One additional advantage of DirectX is that many commercial and open source multimedia CODECs support DirectX. Thus, if one applies DirectX technology in windows based multichannel visual monitoring systems, one may achieve performance gains and flexibility in the choice of video compression CODECs. In this paper, we present a multichannel monitoring system efficiently designed based upon DirectX. Improvement of performances in respect of speed in display, recording, retrieval and playback of video data is analyzed and verified through experiments.

The purpose of this study was to investigate the effects of achivement goal orientation and situational goal climate on motor performance in Bowling. Subjects were 243 male college students enrolled Bowling classes. Among the subject 40 ego-involvements and 40 task involvements are sytemically assigned to one of the following situational goal climate conditions: a) competitive goal climate, b) performance oriented goal climate group. All subjects participated in 8 weeks of bowling practice prior to the onset of the experimental manipulation. At the end of this practice period, subjects participated in 5 week of post test. The design was a 2×2×5 (achievement goal orientations × situational goal climate × performance trials) repeated-measure factorial design, with trials as the repeated mesure. One-way and three-way ANOVA was used to best and analysis the proposed hypothesis in the study. We obtained the following results by the investigation of the collected data. Achievement goal orientations and situational goal climate was not able to predict exercise performance well. However, with task-involved subjects from the condition of performance oriented goal climate, performance was shown to be high.
급성 연쇄상구균 감염후 사구체 신염에 동반된 고혈압 뇌증 1례

고혈압성 뇌병증은 고혈압 환자에서 고혈압과 관련된 두통, 경련, 시각장애 및 다른 신경학적 장애를 동반하는 증후군이다. 증례는 13세 여자환아로 급성 연쇄상구균 감염후 사구체 신염에 동반된 고혈압성 뇌병증 환자였다. 내원시 혈압은 150/110 mmHg 였고 내원당시 검사소견상 단백뇨, 혈뇨, C3의 감소 소견을 보였다. 내원 2일째 자기공명영상을 시행하였고 스핀에코 T2 강조영상에서 양 후두엽과 후 측두엽에 고신호의 이상 부위들이 발견되었다. 치료후 실시한 자기공명영상은 정상 소견을 보였다. 본 저자들은 급성 사구체 신염 환자에서 자기공명영상으로 고혈압성 뇌병증을 진단하고 치료한 1례를 문헌고찰과 함께 보고하는 바이다. Hypertensive encephalopathy is a syndrome consisting of headache, seizures, visual changes, and other neurologic disturbances in patients with elevated systemic blood pressure. We experienced a 13-year-old girl who presented with the manifestations of hypertensive encephalopathy in acute post-streptococcal glomerulonephritis. She visited our hospital because of generalized tonic-clonic seizure after severe headache. On admission her blood pressure was 150/110 mmHg and initial laboratory findings revealed proteinuria, hematuria and decreased C3 level and, T2-weighted MR image showed increased T2 signal in both occipital lobes, suggesting cerebral edema. On follow-up MRI, pathologic lesions were improved. We described a case of hypertensive encephalopathy in acute post-streptococcal glomerulonephritis diagnosed by MRI with a brief review of some related literatures.
결핵성 수막염 환자에서 결핵균 30 kDa 및 32 kDa 단백항원에 대한 항체반응의 비교

The 30 and 32 kDa antigens from Mycobacterium tuberculosis H37Rv culture filtrates, identified as biologically important proteins in the immune responses against mycobacterial infection, were purified and used in enzyme linked ummunosorbent assay (ELISA) for the determination in specific IgG and IgM levels in cerebrospinal fluids of 15 patients with tuberculous meningitis and 17 controls with nontuberculous diseases. High reactivity to both antigens was observed in tuberculous meningitis. Mean IgG and IgM antibody levels differed significantly (P < 0.001) between patients and con trols. Mean IgG antibody levels were also higher than IgM levels in tuberculous meningitis. A comparison of the antibody levels against the 30 and 32 kDa antigen within the tuberculous meningitis patients showed higher IgG reactivity to the 30 kDa than to the 32 kDa antigen, suggesting that the antibody response of these patients is directed predominantly against the 30 kDa protein. However, the patterns of reactivity to 30/32 kDa, 30 kDa and 32 kDa antigen in individual subjects were similar. By the cut-off value adding 2 stsndard deviation to the mean absorbance of controls, the sensitivity and specificity of the IgG antibody to the 30 kDa antigen were 100% and 94.4%, respectively. These values were higher than those obtained by 30/ 32 kDa and 32 kDa antigen. From the above results, it is suggested that the 30 kDa antigen may be dominant antigen and more valuable in the diagnosis of tuberculous meningitis than 32 kDa antigen.
