Sweating is natural phenomenon necessary for the regulation of an individual's body-temperature. The secretion of sweat is mediated by a portion of our vegetative nervous system(the sympathetic nervous system). In some people, this system is working at a very high activity level, far higher than needed to keep a constant temperature. This condition is referred to as hyperhidrosis. Especially excessive sweating of the hands and the feet is palmoplantar hyperhidrosis or volar hyperhidrosis. This is by far the most distressing condition. It was founded that the first important cause of this was emotional factor. The hands are much more exposed in social and prefessional activities than any other part of our body. Many individuals with palmoplantar hyperhidrosis are limited in their choice of proffession, because unable to manipulate materials sensitive to humidity or reluctant to shake hands; some patients arrive to the point to avoid social contact. The occidental medical treatments for palmoplantar hyperhidrosis include application of topical agents(chemical antiperspirants such as aluminum chloride), iontophoresis(treatment with electrical current), or surgery(thoracic sympathectomy). It was reported that the most effective treatment was thoracic sympathectomy. So this study was started to find the easy and effective oriental medical treatments against the occidental medical treatments through the oriental medical literature. The occidental medical idea for palmoplantar hyperhidrosis is only limited in neurologic system, so surgery is the best treatment. But the oriental medical idea for palmoplantar hyperhidrosis is much wider, so the oriental medical causes and treatments for this are able to be veriety. And the oriental medical teatment is freely in treating the patients of palmoplantar hyperhidrosis, because entire idea including pulse, facial color, mental condition, constitution and other symptom exists in the oriental medicine. The results of a bibliographic study of causes and treatments for palmoplantar are as follows; 1. The main causes of pa1moplantar hyperhidrosis are heat in the stomach, damp-heat in the spleen and the stomach, insufficiency of the spleen-qi and the stomach-qi, deficiency of the spleen-yin and the stomach-yin, and the others are the stomach-cold syndrome, stasis of blood and dyspepsia in the stomach, disorder of the liver-qi, deficiency of the heart-yin and the kidney-yin, deficiency of the heart-yang and the kidney-yang, stagnated heat in the liver and the spleen, the lung channel-heat etc. 2. The main methods of medical treatments for palmoplantar hyperhidrosis are clearing out the stomach-heat, eliminating dampness and heat in the spleen and the stomach, invigorating the spleen-qi and the stomach-qi, reinforcing the spleen-yin and the stomach-yin, warming the stomach, relaxing the liver and alleviating of mental depression and tonifying the heart and the kidney etc. 3. The main prescriptions of palmoplantar hyperhidrosis are Taesihotang, Palmultang-kakam, Samyeongbaechusan, Chongbisan, Sasammaekmundongtang, the others are Leejungtang, Hwangkikonjungtang, Seungkitang, Boyumtang, Baekhotang, Chongsimyonjayum, Moyrosan, etc. 4. Local medicine for external use are liquid after boiling alum in water for about 1 or 2 hours, liquid after boiling alum and pueraria root in water and liquid after boiling stragalus root, pueraria root, ledebouriella root and schizonepeta in water, etc. 5. The methods of acupuncture therapy include invigorating Bokyru, Yumkuk and purgating Hapkouk, or invigorating Bokyru, Kihae and purgating Hapkouk, or steadying Hapkouk, Nokung.

Sympathetic skin response (SSR) is defined as a minute change of skin potential after electrical stimulation. This test measures the change in voltage that originates from the surface of the skin and is attributed to sudomotor activity. The aim of this study was to define the criteria for validation of the responses. 40 normal subjects (20-73 years of age) with non-sympathetic dysfunction were tested and SSR was generated form all subjects. SSR latency was 1331.22${\pm}$177.51ms in the right palm, 1331.74${\pm}$156.42ms in the left palm, 1851.79${\pm}$220.99ms in the right sole, and 1874.10${\pm}$215.01ms in the left sole. And SSR amplitude was 595.83${\pm}$221.16${\mu}$V in the right palm, 605.33${\pm}$226.45${\mu}$V in the left palm, 291.76${\pm}$133.36${\mu}$V in the right sole, and 288.77${\pm}$129.70${\mu}$ V in the left sole. SSR latency and amplitude had no significantly difference between the right and the left side. SSR latency was consistently shorter (p<0.001) and SSR amplitude higher (p<0.001) in feet than in hands. SSR waveforms were P-type (32 subjects, 75%) and N-type (8 subjects, 25%), respectively. The SSR latency and amplitude in palms/soles were closely correlated with age (p<0.05) and height (p<0.05). The SSR test is one of methods assessing impairment of sympathetic fibers in peripheral neuropathy as well as a disorder of sympathetic system in other diseases and so our results from normal healthy subjects can be used as clinical criteria for SSR test.

The aim of this study was to investigate how implementation of direct nutrition education differs between nutrition teachers and dietitians in Gyeonggi Area. In this study, we collected data from 107 nutrition teachers and 129 dietitians in 2012. Among those who have answered they implemented direct nutrition education for the last one year, 36% were nutrition teachers and 10% were dietitians (p < 0.05). Among subjects who implemented direct education, a significantly greater percentage of nutrition teachers used a class as an education time to conduct creative hands-on-activity compare to dietitians (p < 0.05). However, for most dietitians, school meal time was more commonly used for direct nutrition education. When asked to make a suggestion regarding improvement for school nutrition education, the highest rate of people chose simplification of school administrative work (4.68 points) was needed. Developing nutrition education (4.55 points) showed the next highest rate. The rest of the answers were the following order; regular training of teaching methods (4.50 points), increasing awareness of school teachers (4.50 points), improving school facilities and financial support (4.47 points), preparing teaching plan (4.46 points), providing incentive for direct education (4.26 points), organizing regular class for nutrition education (4.17 points), and placing nutrition teachers (4.16 points). This study provides useful information including manageable workload of nutrition teachers and dietitians, capacity building and supportive school environment to be delivered with respect to nutrition education system in South Korea.

The most of virtual reality headset have the separated controllers while they put on the headset; so the users may feel the discomfort and burden for the operation. In this paper, a novel virtual reality headset system using the EOG (electro-oculogram) is proposed and it has a distinguished feature that the user does not need to control the virtual reality headset by the hands, but the displayed contents are controllable by the electrical activity of the user's brain. The proposed system consist of the mobile device, a virtual reality headset, and an EOG headset for data acquisition. The system is implemented by using the Unity3D engine for the signal processing and controller, and the concept is confirmed through the implementation that it is more interesting and easier to control the virtual reality headset.

Near-infrared spectroscopy (NIRS) can be used to monitor brain activation by measuring changes in the concentration of oxy- and deoxy-hemoglobin (Hb) by their different spectra in the near-infrared range. Because NIRS is a noninvasive, highly flexible and portable device, it is very suitable to study brain activation when a human repeatedly performs a manipulative task, and possibly provides useful information to construct human adaptive mechatronics (HAM). There is some evidence that the dorsolateral prefrontal cortex (DLPFC) plays a major role in working memory and it is proposed that the use of working memory decreases as a human develops manipulative skills. In the present study, we investigated the activation of the dorsolateral prefrontal cortex (DLPFC) of the brain in Brodmann's areas 9 and 46 in drawing tasks to examine whether NIRS can measure the changes of DLPFC activation as a human develops manipulative skills. Subjects performed a mirror image drawing task and a square drawing task by ones' left hands. In the mirror image task the subject drew following a star shape based on a mirror image of it, but square drawing did not involve mirror image and was estimated to be simpler. The changes of the concentration of oxy-Hb was higher in the mirror image drawing than the square drawing in most subjects. The changes of oxy-Hb decreased as the subject repeated the drawing task in most subjects. In conclusion, The activation of DLPFC measured by NIRS can reflect the brain activity in the development of manipulative skills.

In Raynaud's phenomenon, the authors measured finger blood flow after ice water exposure by analyzing the time activity curve of radionuclide angiography on both hands. The results were as follows: 1) The digital blood flow did not decrease after ice water exposure in normal subjects. 2) In the patients with Raynaud's phenomenon, there were two groups: the one had decreased digital blood flow after cold exposure, and the other had paradoxically increased digital blood flow after cold exposure. 3) There was no difference in the digital blood flow of hand in room temperature between the normal and the patients with reduced digital blood flow after cold exposure, but the digital blood flow of the hand in room temperature was markedly reduced in the patients with paradoxically increased flow after cold exposure. 4) In the static image the difference was not significant in comparision with the dynamic study, because it represents pooling of the blood in the vein rather than flow. 5) After the treatment with nifedipine, the digital blood flow increased. In conclusion, the radionuclide angiography was useful in measuring the digital blood flow in Raynaud's phenomenon, and further studies with various drugs is expected.

Objective: To compare the analgesic effects and adverse drug reactions (ADRs) of fentanyl intravenous patient-controlled analgesia (ivPCA) with nefopam, a centrally acting analgesic agent with demonstrated opioid sparing activity, as compared to ketorolac in a tertiary teaching hospital. Methods: A retrospective evaluation of electronic medical records was conducted on patient records including either nefopam or ketorolac with opioid ivPCA for post-operative pain management in general surgery department from January to December 2014. The status of pain control and ADRs were collected. Results: Out of 6,330 general surgery cases, nefopam was given in 153 prescriptions (6.9%) and ketorolac in 81 prescriptions (3.6%). The level of pain control was not different between two groups (70.9% vs. 75.3%; p = 0.51), but ADRs were more frequently reported in nefopam group (9.8% vs. 2.5%; p < 0.05). New ADRs of hot flushes (n = 1) and paresthesia in hands (n = 1) were reported in nefopam group and they were unlisted in the approved package insert. No serious ADRs were reported in both groups. Conclusion: Our findings presented that nefopam showed a similar analgesic effect and higher ADR rates compared to ketorolac as an adjuvant to fentanyl iv PCA for post-operative pain management in general surgery patients in South Korea.

Various types of bio wood chip for fermentation-extinction of food waste was investigated by comparing their different pore structure with the performance of weight loss rate and microbial activity. The fermentation-extinction of food waste with bio wood chip was examined by adding 700~1,500g of food waste every day during 15 days to the fermentation-extinction reactor with condition of $30{\sim}50^{\circ}C$ temperature and 30~70% humidity, where 1,500g of bio wood chips were existed. The bio wood chips used in this experiment were categorized into 4 different types; microbial-mixing type(A biochip), macro pore type(B biochip) under $2{\mu}m$ of pore size, micro pore type of wood-chips(C biochip) under $0.1{\mu}m$ of pore size, viscous & sticky type(D biochip). As a result, A, B, C, D bio wood chip exhibited 85%, 63%, 92%, 73% weight loss of food waste with fermentation-extinction. The maximum weight loss of food waste was obtained at the fermentation-extinction experiments by using C bio wood chip. On the other hands, the maximum ratio of ATP to COD and TN was obtained from $3.00{\times}10^{-10}$ and $2.31{\times}10^{-11}$ in the case of C bio wood chip, comparing with other types of bio wood chip. Consequently, the performance of weight loss rate was affected with the micro pore structure of bio wood chip which have an advantage of extensive microbial activity space in the fermentation-extinction of food waste.

The purpose of this study was to compare and evaluate various hand functions in the most common position (chair sitting, standing, floor sitting) used by cerebral palsied children with spastic diplegia. The results, analysed statistically, could be useful in suggesting treatment strategy for the improvement of hand function in such patient. For this study, 27 children mild or moderate spastic diplegia were chosen. They were patients of the Rehabilitation Hospital, Yonsei University Medical Center. Both dominant and nondominant hands were tested by the Box and Block Test. Bilateral hand function was tested by bead striding and card sorting activities. Collected data was analysed using univariate correlation analysis and MANOVA. Results were as follows: 1) In chair sitting there was a significant positive correlation between dominant hand scores in the Bloc and Box Test and chronological age, gestation period, and time of treatment initiation. In bilateral hand function, card sorting scores correlated positively with time of treatment initiation. 2) In standing, there was a significantly positive correlation between dominant hand scores in the Block and Box Test and time of treatment initiation. 3) In floor sitting, there was a significantly positive correlation between the dominance hand scores in the Block and Box Test and the tine of treatment initiation. Bead stringing, a bilateral hand activity, correlated positively with gestation period and birth weight but negatively with the postnatal incubation period. 4) That score of children who walked showed no significant difference in any of the three postures. 5) Highest test scores in children who could nat walk were in the Box and Block Test for nondominant hand in bead stringing for bilateral hand function. There scores occurred with the children in thee chair sitting posture. The results showed that, in order to improve hand function in children with spastic diplegia, it is necessary to maintain a well supported upright trunk posture with variations allowed for relevance to the chosen position of thee improvements hand activity being performed.
