Objectives : To investigate the nature of emotional responsiveness in norma) adults, we exam the emotional responses to emotional pictures in an evaluative space defined by arousal and valence. Methods : Subjects were instructed to rate the arousal and valence that they experienced from the presentation of one of two sets of 60 emotional pictures. These two picture sets were comprised of 107 pictures : 101 selected from Intetnational Affective Pictures System and six pictures from our own collection. According to "evaluative space model", the authors set an evaluative space defined by the arousal scores as independent variable and the valence scores as dependent variable. In this evaluative space, one-hundred-and-seven pairs of coordinates representing respective emotional pictures were plotted. With regression analyses, the steepness of the regression lines on the plots with positive emotional responsiveness (n=51) and those with negative emotional responsiveness (n=56) were compared. Results : In the evaluative space, the regression line of negative emotional responsiveness was significantly different from that of positive responsiveness. The slope of negative responsiviveness was significantly steeper than that of positive responsiveness. At a low arousal level, the absolute valence of a positive stimuli was larger than that of a negative picture. Conclusion : This finding indicates that the function of the negative affective responsiveness might be different from that of the positive responsitiveness. IAPS also seems applicable to Korean subjects.

Purpose: The purpose of this study was to compare the activities of the abdominal and neck flexor muscles of children with and without cerebral palsy (CP) while lifting the head in a supine position. Methods: The subjects were eight children with CP and eight children without the disease. The activities of the external abdominal oblique (EO), internal abdominal oblique (IO), rectus abdominis (RA), sternocleidomastoid (SCM), and RA/SCM muscles were collected by surface electromyography (EMG) when the children lifted their heads. A Mann-Whitney U test was used to compare the activity of each muscle during the head-lifting exercise. Statistical significance was accepted at p<0.05. Results: The activities of the EO, IO, and RA, and RA/SCM muscles differed significantly between the children with and without CP, but there was no significant between-group difference in the activity of the SCM muscle. Conclusion: These findings suggest that the abdominal muscles are not employed as much in the activities of children with CP compared to those without the disease. Additionally, those with CP were more dependent on the neck flexor muscle during the head-lifting exercise in a supine position.

웃입술에 발생한 혈관 평활근종 1예

최진혁,임성욱,이호중,권순욱,이정우,서무규,장태정 대한피부과학회 2003 大韓皮膚科學會誌 Vol.41 No.9

Angioleiomyoma is a benign solitary tumor that arises from muscle layer of the vein walls and mainly develops on the lower extremities of middle-aged women. But it is rarely found on the lip. We report an unusual case of angioleiomyoma in a 27-year-old male who showed an asymptomatic, 03 × 0.5 cm sized mass on the upper lip for 3 years. Histopathologically, various sized, numerous vessels and bundles of smooth muscle fibers were observed in the dermis. (Korean J Dermatol 2003;41(9) : 1259~1261)

A few case of deep granulomatous cutaneous infection have been reported in the Korean dermatologic literature, but Trichophyton(T.) mentagrophytes granuloma is rare. We report a case of Trichophytic granuloma caused by T. mentagrophytes in a 10-year-old male, who showed three, mild pruritic, coin to walnut-sized, erythematous plaques with indurations and crusts on the face for 1 month. Fungal culture of the biopsy specimen and scales of the lesion revealed T. mentagrophytes. Histopathologic examination of the skin lesion showed chronic granulomatous inflammation in the dermis and fungal hyphae in the hair shaft. After four weeks of terbinafine administration, lesions were cleared with mild erythematous macules. [Kor J Med Mycol 7(2): 92-96]

Cooperative Manipulation of a Virtual Object by Multiple Remote Users

Choi, Hyouk-Ryeol,Ryew, Sung-Moo The Korean Society of Mechanical Engineers 2000 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.14 No.9

In this paper, we explore the issues of force display in the cooperative virtual environment shared by multiple users distributed over the network with heterogeneous hardware platforms. The proposed method is to cope with the problem of small time delay and the difference of sampling rate in the distributed configuration. In the proposed approach the interaction forces of the participants are just treated as the independent sources of acceleration. Thus the action of a participant simply changes the acceleration of the virtual object and consequently the states of the virtual object will be updated. When the updated states are reported to all the participants, the information on the time of state changes is delivered, too. Employing the discrete state information updated by the other users, each user modifies his own virtual environment and pseudo-realtime simulation can be realized. Excluding the software interface and the communication technique, it is proposed the simulation method for the operation of respective users and the way of calculating the driving input to the display device. For experimental verification we construct a cooperative virtual environment shared by two remote users and outline the results of experiments.

저자들은 1981년 1월부터 1988년 6월까지 인제의대 부산백병원 내과에서 위장관계통의 평활근육종 10예를 경험하고 이들에 대한 상세한 임상적 관찰을 실시하여 그 결과를 보고하고자 한다. A clinical study was performed on 10 cases of leiomyosarcoma of the gastrointestinal system admitted to Inje Medical College, Pusan Paik Hospital, from 1981 to 1988, and the following results were obtained. 1) The locations of the leiomyosarcoma were the stomach(3 cases), the duodenum(3 cases) the jejunum(2 cases), the rectum(1 case) and the omentum(1 case), in order of frequency. The age distribution was wide from 12 years to 60 years, the most prevalent age group was fourth decade(4 cases) and the average age was 43 years. The ratio of male to female was 6 : 4, the male being 6 cases and the female 4 cases. 2) The most common symptom was gastrointestinal hemorrhage, 7 cases out of 10, and the duration of illness was variable, from 3 days to 5 years, but was loot closely related to the severity of illness. 3) The incidence of the leiomyosarcoma of the gastrointestinal system as compared with the other malignant tumor in the same period was about 0.9%, the stomach 0.3%, the small intestine 38.5%(the duofenurn 37.5%, the jejunum 40.0%), the rectum 0.8%, and the omentum 33.3%, which was consistent with other monographs. 4) All 10 cases underwent surgical intervention, postoperative chemotherapy was done on 3 cases in which the regimen was VAC(Vincristine, Adriamycin, Cyclophosphamide) and postoperative radiotherapy was done on 1 case. In brief, the leiomyosarcoma of the gastrointestinal system was most frequent in the small intestine, gastrointestinal hemorrhage the commonest clinical symptom, the duration of the illness was mainly less than 1 year, involved any age group and the overall incidence was less then 1% of the gastrointestinal malignancy.

Choi, Ho-Suk,Shin, Won-Seob,Shim, Jae-Kwang,Choi, Sung-Jin,Bang, Dae-Hyouk The Korean Society of Physical Therapy 2014 대한물리치료학회지 Vol.26 No.6

Purpose: The purpose of this study was to investigate the correlations between functional movement screen (FMS) and ankle dysfunctions in subjects with chronic ankle instability (CAI). Methods: This study was a cross-sectional study of 20 participants with CAI. The ankle dorsiflexion range of motion (ROM), Foot and Ankle Disability Index (FADI), center of pressure (COP) path length, and COP velocity for ankle dysfunction were measured in all the subjects. All the subjects underwent the FMS concerned with ankle functions consisted of deep squats, hurdle steps and in-line lunges. The Spearman rank-order correlation coefficient was used to determine relationship between the ankle ROM, FADI, COP and FMS. Results: The results of the deep squat and in-line lunge exercises revealed a significant correlation with the ankle dorsiflexion ROM, FADI, COP path length, and COP velocity. The hurdle step showed no correlation with the ankle dorsiflexion ROM and FADI but a significant relationship with the COP path length and COP velocity. Conclusion: The results of this study showed that relationship deep squat and in-line lunge and it is suggested that an assessment tool using ankle dorsiflexion ROM and ankle instability would be clinically effective.
