Purpose: An increase in the use of functional near-infrared spectroscopy (fNIR), which improves the efficiency of investigation into functional aspects of the brain and helps to overcome the limitations of existing imaging methods (e.g., fMRI, PET) in studies pertaining to stuttering onset has been seen as of late. The purpose of this study was to compare the patterns of brain activation, particularly the frontal lobe, of ordinary children and children in the incipient phase of stuttering by using fNIR. Methods: Using fNIR, we estimated oxy-hemoglobin, deoxy-hemoglobin and overall hemoglobin levels in two groups of children: a group comprised of 10 developmental children who stutter and another group comprised of 10 ordinary children while they were reading and monologizing. A t-test was performed to verify the difference in the oxy-hemoglobin, deoxy-hemoglobin and overall hemoglobin levels that were measured in the two groups. Results: First, a significant difference was observed in oxy-hemoglobin measurements between the two groups primarily in the motor cortex areas while they were reading the materials and reciting the monologue. Second, a significant difference was found in deoxy-hemoglobin measurements between the two groups primarily in the motor cortex area while they were performing two different tasks. Third, a significant difference was found in overall hemoglobin levels between the two groups primarily in the motor cortex area while they were carrying out two different tasks. Conclusions: Based on comprehensive consideration of the results, a conclusion can be drawn that stuttering children, compared with ordinary children, exhibit differences in terms of oxygen and de-oxygen processes in the motor cortex area of frontal lobe.

Purpose: It plays an important role for special education teachers and general education teachers to resolve stuttering and school life adaption of school age children who stutter. The purpose of this study was to clarify differences, if any, in the perception of school-age students who stutter between general education teachers and special education teachers. Methods: For this purpose, a questionnaire survey was completed by 193 special education teachers and 225 general education teachers. Results: First, it was found that there are significant differences in the said perception between the two groups in terms of all the questions related to the intrinsic nature of stuttering, and overall, the group of special education teachers had a relatively higher level of perception. Second, there are significant differences in the perception between the two groups in terms of most of the questions related to school-age students who stutter, and for some questions, general education teachers showed a relatively higher level of perception. Third, there were significant differences in the perception between the two groups regarding some questions associated with the roles of teacher. Finally, it was shown that there were significant differences in the perception between the two groups in terms of all the questions related to an intramural support system, and specifically, general education teachers had a relatively higher level of perception. Conclusions: Taken together, there were significant differences in the perception of school-age students who stutter between the two teacher groups: while special education teachers had higher levels of perception of conception related to the nature of stuttering, general education teachers exhibited higher levels of perception of practicalities concerning an intramural support system.

The flow meter detects the vortex made by the bluff body which is inside of the pipe that has flowing fluids and calculate the velocity of the fluid. The sensor was manufactured using sensor body and piezo ceramics as the result of the creative design in engineering. The preexistence was analyzed and considered manufacture process and experiment. The sensor body was made after modifying sensor housing and transmitter. Using an elastic tape, copper foil and electric wire, first experiment was conducted. After holding with a vise, impulse was given to the transmitter and signal was captured. Scale is the 100㎳/dev for horizontal direction, 100㎷/dev for vertical direction. And the signal of the preexistence and proto-type was similar with its amplitude and period. Also, through frequency analysis, piezo ceramics’ thickness was selected and it can reduce the cost and error from development step. The experiments include impulse and periodic impulse test.

컴솔 멀티피직스를 이용한 양극형 1회선 HVDC의 전계 해석

안종복(Jong-Bok Ahn),박철원(Chul-Won Park) 한국조명·전기설비학회 2018 조명·전기설비학회논문지 Vol.32 No.9

Recently, there has been an increasing interest in HVDC(High Voltage Direct Current) transmission as a core technology required for a Super grid. Compared with HVAC(High Voltage Alternating Current) transmission, HVDC transmission has no loss due to skin effect and reactance components, so long-distance power transmission is possible, and asynchronous power system can be interconnected. Also, in case of a DC electric field, there is no induction phenomenon. However, the human body may cause irritation such as electrostatic discharge and discomfort, therefore electric field analysis through simulation is absolutely necessary. In this paper, electric field simulation was performed using COMSOL Multiphysics, a multi-physics analysis program, for a Bipolar single line DC ±400kV, DC ±500kV, DC ±800kV model. In order to verify the validity of the simulation, comparative analysis with the related literature was conducted.

This study was intended to analyze how well people with right hemisphere damage can understand Korean proverbs. This study used a between-subject design and within-subjects design where all subjects participate in the three experiments for 10 hospitalized patients of whose average age is 66.1 years old and 10 normal adults in the same age range. Experiment 1 was to make up Korean proverb related stories and suggest it in written, Experiment II was to suggest a picture presenting a Korean proverb and the proverb itself directly, and Experiment III was to make up a story related to a Korean proverb and tell it auditory. Five Korea proverbs were used for each experiment; 15 in total. The results were as follows: First, there was a significant difference in understanding of Korean proverbs between normal adults and people with right hemisphere damage. Second, there was no significant difference of understanding between them by stimulating methods to suggest Korean proverbs. Third, people with right hemisphere damage had a tendency to interpret Korean proverbs literally as a total wrong reaction was composed of 55.36%. Considering the above the results, it can be said that people with right hemisphere damage have less understanding of Korean proverbs than normal adults, which is not affected by a way of or a condition of suggesting Korean proverbs in people with RHD, and they are inclined to make literal interpretation of Korean proverbs as they are.

Compared to AC transmission system, DC transmission system has low transmission loss. In addition, DC transmission can interconnect asynchronous power systems. Therefore, many overseas countries are operating DC transmission lines and ±500kV DC transmission lines will be constructed in South Korea. So, in this paper, we try to compare the clearances of obstacles when constructing a DC transmission line in a foreign country for the purpose of calculating the optimal clearance in South Korea. The comparison countries are the United States, Japan, Canada, China, South Africa, and India. As a result of the optimal clearance analysis, it is appropriate to apply the Japanese standard when considering various environmental aspects in South Korea.
