  • Objective : The characteristics of physiological responses of ADHD children to sensory stimulation were examined by types of sensory stimulation, measurement tools, and responses. In addition the behavioral characteristics were examined by analyzing items of common problems according to the measuring tool, frequency, and measurement tools. Methods : A systematic review methods were used. Papers published in the Journal between January, 1990 and December 31, 2011 were searched through Riss4U, MEDLINE /PubMed, CINAH. The main terms searched were "ADHD, Children, Sensory processing, Sensory integration, SP, SSP, SOR, TIE, CSP, SEP, EDR", and 15 papers were analyzed. Results : 1. The number of studies on physiological responses of children with ADHD to sensory stimulation was five (33.33 percent), the number of studies on behavioral responses was ten(66.67%), and the number of studies combined the two kinds of study was two (13.33%), where a total of 15 (100%) papers were analyzed. 2. In five studies on the physiological response, there were three studies using tactile and proprioceptive stimulations and two studies using olfactory, auditory, visual, tactile, and vestibular sensories. 3. In ten studies on the behavioral responses, there were five studies using SP, three studies using SSP, two studies using SOR, one study using TIE, and one study using CSP. Conclusion : In the characteristics of physiological responses of children with ADHD children to sensory stimulation, there was in the action potential of the cells in hand region of the primary sensorimotor cortex neurons. It was analyzed that there was an initial state and it appeared show a obvious and fast habituation in the later state; the time of recovery seemed to have many non-specific responses. In the characteristics of behavioral responses, there were inattention / distraction, vestibular processing, sensory processing related to endurance / tone, modulation of sensory input affecting emotional responses, low energy/weak.

  • Purpose : The headache, one of the symptoms of meningitis, is related to abrupt elevation of intracranial pressure(ICP) or stimulation of intracranial nociceptive structure. However, in cases of mild elevation of ICP or normal findings of cerebrospinal fluid(CSF) analysis, patients sometimes complain of headaches. Therefore, other pathways may contribute to the occurrence of headaches in aseptic meningitis or meningismus. We intend to investigate the role of substance P(SP) and calcitonin gene-related peptide(CGRP) in aseptic meningitis or meningismus. Methods : We measured leukocyte count, the concentration of protein and glucose in CSF and ICP of patients with meningeal irritation sign. We also measured SP and CGRP levels by using immunoassay. We analyzed the relationship between the presence of headache and the value of SP and CGRP. Results : The concentrations of CGRP($18.8{\pm}10.5ng/mL$) in CSF and ICP($14.8{\pm}4.5cmH_2O$) in aseptic meningitis group were significantly higher than in those($14.1{\pm}7.4ng/mL$ and $12.0{\pm}5.1cmH_2O$, respectively) of the meningismus group(P<0.05). There was no significant difference in the SP levels between the two groups. In the aseptic meningitis group, the concentrations of SP and CGRP were significantly higher in the normal ICP group than in the elevated ICP group(P<0.05). Conclusion : Headaches in children with aseptic meningitis or meningismus is considered to be related to the elevation of the CSF levels of SP and CGRP.

  • Purpose : Patients with chronic granulomatous disease (CGD) have genetic mutations in a component of the NADPH oxidase enzyme that is necessary for the generation of the superoxide anion. The profound defect in innate immunity is reflected by the patients susceptibility to catalase-positive bacteria and fungi. In addition, CGD patients display signs of persistent inflammation, which is not associated only with deficient superoxide anion production. The aim of this study was to elucidate the cytokine responses in CGD patients after $TNF-{\alpha}$ stimulation. Methods : Heparinized blood samples were collected from 8 CGD patients and 10 healthy volunteers. Monocytes ($1{\times}10^6cell/well$) isolated by the magnet cell isolation system were incubated with a constant amount of $TNF-{\alpha}$ (10 ng/mL) at $37^{\circ}C$ for 6 h. Incubated cells were harvested at 60-min intervals for IL-8 and IL-10 mRNA analysis, and the supernatant was collected at the same intervals to determine IL-8 and IL-10 expression. Monocytes from healthy volunteers were also incubated with antioxidants followed by $TNF-{\alpha}$ stimulation for IL-8 and IL-10 expression. Results : In CGD patients, a high expression of IL-8 together with a significantly higher IL-10 expression than in the healthy controls was seen after $TNF-{\alpha}$ stimulation. Moreover, normal monocytes treated with antioxidants exhibited increased IL-8 responses. Conclusion : The absence of phagocyte-derived reactive oxidants in CGD might be associated with a dysregulated production of pro- and antiinflammatory cytokines. Additional research related to reactive oxidants is needed to clarify the role of cytokines in CGD patients.

  • Background: Thoracic sympathicotomy has been used safely and successfully to manage palmar hyperhidrosis. The preoperative and postoperative recording of Sympathetic Skin Responses(SSR) was performed for objective evaluation and follow-up of thoracic sympathicotomy in hyperhidrosis patients, and also for ascertaining the clinical usefullness of SSR. Material and Method: The recording of SSR was performed on 15 patients suffering from palmar hyperhidrosis with Medelec Sapphire Plus electromyogragh before and after thoracic sympathicotomy. Eletrical stimuli on the right median nerve was made in patients in supine position and results were recorded on right and left palms with soles at the same time by 4 channels. Skin temperatures were also monitored simultaneously. T2,3 sympathicotomy was performed with VATS in every patients. SSR was done in 2 patients one month later. Result: Clinically, all patients had symptomatic improvement with satisfaction. Postoperative complication was small amount of residual pneumothorax in 5 patients but it was absorbed sponteneously. There was no recurrence during follow-up period and ten patients(66%) complained compensatory hyperhidrosis. After operation, SSR change was shown in every 15 patients. Abolition of SSR on both palms was achieved in 12 patients(80%) and on both soles in 6 patients. In the other 3 patients, the latencies were significantly delayed and the amplitudes were significantly reduced at both palms and soles. In two patients who were examined at one month later after operation, similar results with postoperative SSRs were shown. The skin temperature on preoperative both palm and sole were lower than normal temperature, and those on postoperative both palm and sole were increased. Those had statistical significance(p<0.05), and the temperature on the palm was increased higher that than on the sole. Conclusion: After thoracic sympathicotomy was performed on palmar hyperhidrosis patients, an increment of skin temperatures and SSR changes were achieved at both palms and soles of all patients. Palmar SSRs were completely abolished in 12 patients(80%), and similar results of postoperative SSRs were achieved. The recording of SSR may be useful to easily and objectively assess the completeness of sympathicotomy and the follow-up of recurrence in hyperhidrosis patients.

  • Background: There is no standardized tool and parameter that can accurately assess the sympathetic function before and after performing sympathectomy in patients with primary palmar hyperhidrosis. We examined the effective-ness of the sympathetic skin response (SSR) study for documenting the change of sympathetic denervation before and after performing selective thoracic sympathicotomy. Material and Method: We prospectively investigated the SSR from 12 healthy subjects who were diagnosed with primary hyperhidrosis. Each SSR was recorded on the right palm or sole with electrical stimuli applied to the skin at the left wrist and foot and vice versa for the controlateral side. This test was performed before, 2 weeks and 1 year after selective thoracic sympathicotomy. The data was corrected for the onset latency and the amplitude of the SSR (n=24). Result: The mean age of the 12 patients was $24.6{\pm}0.4$ years (range: 19~36) and the gender ratio was 1 : 0.7. The mean values of the preoperative, postoperative 2 weeks and postoperative 1 year onset latency and amplitude of the palmar side (n=24) were $1.46{\pm}0.24$ msec and $6,043{\pm}2,339{\mu}V$, $1.63{\pm}0.42$ msec and $823{\pm}638{\mu}V$, and $1.44{\pm}0.39$ msec and $2,412{\pm}1,546{\mu}V$, respectively. The mean values of the plantar side (n=38) were $1.83{\pm}0.42$ msec and $2,816{\pm}1,694{\mu}V$, $2.16{\pm}0.39$ msec and $1,445{\pm}1,281{\mu}V$ and $1.95{\pm}0.25$ msec and $1,622{\pm}865{\mu}V$, respectively. Among the documented parameters, only the palmar amplitude (p=0.002) showed statistical significance in recording the change of the sympathetic system within the same individual for the pre and postoperative period. Conclusion: The SSR amplitude ratio may be a useful parameter for documenting the efficacy of sympathetic denervation after selective sympathicotomy.

  • This study reviewed and analyzed English-written studies using a rhythmic tapping task for motor control of children with autism spectrum disorder (ASD). Inclusion criteria for the participants were children with ASD and typically developing (TD) children. The keywords used for the outcome variables included rhythmic tapping, timed movement, and synchronization. Ten studies were included in the final analysis. The included studies were analyzed in terms of target variables, auditory stimuli, and measurements. A meta-analysis was also conducted to examine how children with ASD performed rhythmic tapping tasks compared to children with TD. In the identified studies, five variables were used: timed movement control, timing reproduction, bimanual coordination, synchronization, and interpersonal synchronization. It was found that rhythmic tapping performance was analyzed in terms of accuracy and precision of the movement and reported as significantly correlated to social skills measures. The meta-analysis results showed that there were no significant differences between the ASD and TD groups in continuing rhythmic movements when the presented auditory stimuli ended, whereas there were significant group differences in their ability to maintain their motor performance consistently and to synchronize with auditory cue or with others. These results support the rhythmic tapping task as an effective measure for not only motor control but also social skills development in children with ASD.

  • Intra-body communication' is a wireless communication technology that uses a body as a transmission medium for electrical signals. Generally, an 'earth ground' is used to create an electric field for operating the system; however this operating method could not apply to telemetry for implanted neural prosthetic devices. So this paper suggests a newly designed intra-body communication for neural prosthetic devices. A floating system which has a couple of electrodes with body was studied to remove an influence of the 'earth ground'. We found that 10MHz is the most suitable carrier frequency in skin experiments and over 3MHz in subcutaneous experiments. The system has been applied to a current stimulator circuit for cochlear implant that uses pulse width modulation (PWM) method at 480kbps rate successfully.

  • The demand for recognizing the color as well as the object shape is increasing to use the detailed information, because-the expense of color input/output devices become cheap. The research on the color correction should be researched for the exact color presentation and color reproduction of color input/output systems. In this paper, we researched on the color correction of color scanner. The characterization of color scanner is a two step process of gray-balancing and color transformation. The decoupling of the gray-balancing from the color transformation enables the portability of the scanner characterization. We used the least square methods for the line fitting and the Neural Network for the storage space and computation speed. The output of Neural Network is similar to the target value in three-dimensional tristimulus space. The proposed color correction method can be used for all scanners of a manufacturer's model because of the portability.

  • Die Hedeutungen von drei Verben anregen, aufregen, erregen werden durch '흥분시키다' ohne Unterschied im Deutsch-Koreanisch $W\"{o}rterbuch{\;}erkl\"{a}rt$. Aber sie haben verschiedene Bedeutungen, was man durch einen Vergleich der Valenz feststellen kann und durch eine verschiedene $Bedeutungserkl\"{a}rung$ zu unterscheiden versuchen sollte. Die drei Verben haben die Argumentenkombination 'Origo + $Vorgangstr\"{a}ger$' gemeinsam. Aber erregen muss noch in 2 Sememe eingeteilt werden: erregen 1. '무엇이 누구를 아주 화나게 하거나, 아주 신경질적으로 만들다'(불유쾌한 홍분상태에 빠뜨리다) erregen 2. '무엇이 누구를 성적으로 또는 기쁘게 흥분시키다'(즐거운 흥분상태에 빠뜨리다) erregen 2. muss wiederum in 2 Eedeutungsvarianten aufgeteilt werden: erregen 2.1. '성적인 흥분상태에 빠뜨리다' erregen 2.2. '성적인 흥분은 아니지만, 기쁜 흥분상태에 빠뜨리다' erregen 2.1. und erregen 2.2. werden voneinander unterschieden durch die verschiedene semantische Klasse der $Mominativerg\"{a}nzung$: 'Sexueller Anblick' erscheint fur die semantische Klasse der $Nominativerg\"{a}nzung$ von erregen 2.1.. 'Musik' erscheint fur die semantische Klasse der $Nominativerg\"{a}inzung$ von erregen 2.2.. erregen 1. und aufregen mit negativer Konnotation werden synonymisch verwendet: erregen 1. '무엇이 누구를 아주 화나게 하거나, 아주 신경질적으로 만들다'(불유쾌한 흥분상태에 빠뜨리다) aufregen '무엇이 누구를 아주 화나게 하거나, 아주 신경질적으로 만들다'(불유쾌한 흥분상태에 빠뜨리다) Aber die semantische Klasse $f\"{u}r$ die $Akkusativerg\"{a}nzung$ scheint anders zu sein: 'Mensch odor das $Gem\"{u}t$ eines Menschen' $k\"{o}nnen$ erscheinen $f\"{u}r$ die $Akkusativerg\"{a}nzung$ von erregen 1., $w\"{a}hrend$ nur 'Mensch' $f\"{u}r$ die $Akkusativerg\"{a}nzung$ von aufregen erscheint. Man sollte die Bedeutung und die syntaktische Valenz von anregen anders $erkl\"{a}ren$, je nachdem ein Mensch odor eine $T\"{a}tigkeit$ des $Menschenk\"{o}rpers$ als $Akkusativerg\"{a}nzung$ auftritt: j-n : Kaffee regt(mic) an. '커피가 나를 흥분시키다' Absraktum : das Medikament regt die Verdauung an '약이 소화를 자극하다/촉진하다/북돋우다' Die $Akkusativerg\"{a}nzung$ mit der semantischen Klasse 'Mensch' ist fakultativ weglassbar, $w\"{a}hrend$ sie mit dem Klassem $'T\"{a}tigkeit{\;}des{\;}Menschenk\"{o}rpers'$ obligatorisch ist.
