This study was performed to investigate the masicatory efficiency in patients with temporomandibular disorders (TMDs), especially internal derangement of temporomandibular (TM) joint. For this study, 26 patients after treatment and 33 dental students who had no signs and symptoms of TMDs were selected as the patients group and as the normal group, respectively. Mean treatment duration of the patients was. 5.1 months. Verbal rating scale(VRS) and Visual analogue scale(VAS) were used for recording of subjective symptoms. Treatment index (VAS Ti) derived from VAS was calculated for evaluation of treatment progress and clinical examination was also performed for objective symptoms. BioEGN(Bioresearch Inc., Milwaukee, USA) was used for observation chewing movement pattern on peanut, caramel candy, and gum chewing. Chewing time in second and symptoms after chewing were recorded, and pattern of chewing stroke between in affected side and in contralateral side or between in right in left side were compared, and especially, gum chewing pattern between before and after treatment were also compared in the patients group. The data obtained were analysed by SPSS windows program and the results of this study were as follows : 1. Subjective symptoms evaluated by VAS showed no difference between the two groups, but those by VRS showed slight difference for TM joint pain, head not neck symptoms, and chewing ability. 2. There were no difference at the level of subjective symptoms between the subgroups divided by treatment duration of five months in the patients group. However, value of VAS Ti of pain was higher in subgroup of long treatment duration than that of subgroup of short treatment duration. 3. There were no difference in chewing time for peanut or caramel candy between the two groups, but on caramel candy chewing, the patients group complained slight discomfort after swallowing. Chewing velocity and range of motion on gum chewing after treatment in the patients group showed significant difference and greatly improved compared to those to before treatment, and which were not differ from those of normal subjects. In conclusion, treatment of temporomandibular disorders about for five months would greatly improve chewing ability and movement pattern in most of the patients with TMDs.

Traditionally, keyboards have been one of the most frequently used input devices for information processing using computers. As most computers adopt the Microsoft Windows for their operating system however, the usage of mouse has recently increased to a great extent. Moreover, the mouse has been used as the leading input device in such areas as industrial design and computer aided design. Excessive uses of mouse may cause a severe pain and fatigue on neck and upper limb due to the intensive and repetitive use of corresponding muscles, which renders a decline in efficiency and leads to musculoskeletal disorders. The main purpose of this study is to find the best working conditions to prevent musculoskeletal disorders when using mouse in a neutral posture. Utilizing electromyogram amplitude and Borg's scale, the role change and strength imposed on the muscles were measured and analyzed with and without the forearm support concerned. Also investigated were the effects of changes in elbow forearm supporter.

Anger is the most common emotional trigger causing relapses in individuals with alcohol use disorders (AUDs). The present study intended to investigate the autonomic nervous system (ANS) responses induced by anger in individuals with AUDs. The participants in this study included twelve individuals with AUDs and 14 non-frequent drinkers. Anger was induced in the participants via a 120-second film clip. Before the presentation of this audio-visual stimulus, the ANS responses of the participants were measured for 60 seconds to ascertain their resting state. Subsequently, the participants' ANS responses were measured again for 120 seconds when they were in an emotional state during the presentation of the clip. After the ANS measurements were taken, participants were asked to rate the type of emotion they had experienced as they viewed the film and to report its intensity. The results indicated that the levels of anger experienced by the AUD group were not significantly different from the emotion registered by the control group. However, the ANS responses induced in AUD participants when they were in an emotional state showed blunted skin conductance levels (SCL) and skin conductance responses (SCR) compared to the control group participants. Individuals with AUDs evinced lower emotional arousal than the participants of the control group. These results can help clinicians understand the psychological and physiological responses of individuals with AUDs to anger in order to design effective interventions that would reduce chances of anger and relapse.

This paper suggests the best work conditions, including short break time and number of mouse clicks on a computer, to prevent MSDs(Musculoskeletal Disorders) on VDT(Visual Display Terminal) work. Discomfort measures are calculated according to the Borg's CR-10 Scale. The short break time conditions are grouped into 7, 15, and 30 seconds after every 10-minute work period and the number of mouse clicks are divided into 10 clicks/min, 20clicks/min, and 30clicks/min. The result of the ANOVA on the shift value of subjective discomfort shows the following: 1) Regarding the break time and the number of mouse clicks, there are statistical differences between the measured values for the neck and the wrist(p<0.05). 2) Regarding the number of mouse clicks, there are statistical differences between the measured values for the shoulder and the forearm(p<0.1). 3) Regarding the break time and the number of mouse clicks, there are no statistical differences between the measures values for the eyes, upper arms and back(p<0.1).

Numerical parameters have been developed to diagnose L4/L5 disc patients during repetitive flexions and extensions. Electromyography(EMG) has been used to define the muscle excitation and movement cycle in this study. Twenty healthy subjects and twenty L4/L5 disc patients were recruited for the experiment. The subjective pain levels of patients were recorded as $3.7{\pm}1.6$ according to visual analogue scale where 10 was the maximum pain level. Variance ratio of motion cycle was suggested as a new parameter to examine the consistency of the trunk movement. The results indicated that the temporal EMG pattern such as peak time difference between Quadriceps and Hamstrings, the duration of coexcitation between Erector spinae and Rectus abdominis muscle pairs showed a statistically significant difference between healthy subjects and patients. Variance ratio of External oblique and Internal oblique also showed a statistically significant difference. It is expected that those results could be used for diagnosis by building a database for various back pain patients and healthy subjects. This method can eventually help physicians for early diagnosis and prevention of low back disorders.

The syndrome of reversible posterior leukoencephalopathy syndrome(RPLS) is characterized clinically by acute neurologic signs such as headache, vomiting, confusion, seizures, and visual abnormalities. Radiologically, abnormalities consistent with reversible white matter edema in the occipital and parietal lobes are characteristic. RPLS has often been associated with various systemic disorders, such as hypertensive encefhalopathy, eclampsia, and the use of intravenous or intrathecal immunosuppressive drugs. We report a case of RPLS that occurred after intravenous steroid pulse therapy and treatment with oral cyclophosphamide in a child with nephrotic syndrome, and we emphasize the importance of early recognition of RPLS in the treatment of nephrotic syndrome and appropriate management tn prevent Permanent neurologic disability.

Objective : The purpose of this study was to report the improvement in two patients with different complaints of sleep disorder treated with herbal medication based on the Shanghanlun disease pattern identification diagnostic system (DPIDS), and hypothesize the meaning of word '更'. Methods : According to DPIDS, patients were diagnosed with Taeyang-byung no. 29 provision, and took Gamchogungang-tang herb medication 15 or 90days. The results of administration were evaluated by the hyperhidrosis disease severity scale (HDSS) and the visual analog scale (VAS). Results : After administration of Gamchogungang-tang 15 or 90days, based on 29 provision of Gamchogungang-tang diagnosed according to Shanghanlun provisions, in one case the HDSS decreased from 3 to 1 and the VAS decreased from 10 to 1. In the other case, the VAS decreased from 10 to 1. Conclusions : Each patient not only recovered from symptoms of hyperhidrosis and alopecia areata, but also from sleep disorders following administration of a single medication of Gamchogungang-tang. This case report suggests that the word '更' in the 29 provisions of Shanghanlun means sleep disorder in this case.
