Objectives : This report intended to estimate effects of Jung-an acupuncture on the acquired torticollis caused by muscle contraction. Methods : The patients were treated by Jung-an acupuncture, herb medication and Physical treatment daily. The improvement of the patients was judged by Toronto Western Spasmodic Torticollis Rating Scale(TWSTRS), Tsui's score and Visual Analogue Scale(VAS). Results : After 7 days of treatment, the 2 patients' neck pain and cervical movement were improved. Also, TWSTRS score, Tsui's score and VAS were all reduced. Conclusions : As the Jung-an acupuncture's theological base is organized with meridian theory and myofacial release therapy, We considered the Jung-an acupuncture is effective not only for the skin disease but also for the muscle problem such as torticollis.

Artificial neural network can be used as a diagnosis and predictive method for analyzing patterns in multivariate cases. The goal of this study is diagnosis of the spondylolisthesis from biomedical data that is derived from the shape and orientation of the pelvis and lumbar spine. The data set has six attributes including pelvic incidence, pelvic tilt, lumbar lordosis angle, sacral slope, pelvic radius and grade of spondylolisthesis and two class including normal and abnormal. From University of California at Irvine machine learning repository, 100 normal and 150 spondylolisthesis patient’s data were used for this study. Backpropagation neural network, diagnosis used for diagnosis fo spondylisthesis and the results were described in this paper.

From January through February 2000, the SO_2. NO_2, and VOCs (Volatile organic compounds) concentrations were measured at the total 15 sites (between 6213S and 6214S, between 5846W and 5848W) around the King Sejong Station located in King George Island. The badge type of SO_2 and NO_2 passive diffusion samplers impregnated with 5% Na_2CO_3 and TEA, respectively and VOC passive samplers including activated carbon filter were used. The samplers brought back to the laboratory were analyzed with IC or GC after extracting by distilled pure water, H_2O_2, or CS_2. Considering that the concentration level of each compound analyzed are very low in Antarctica, the blanks and instrumental detection limits were also determined. The blanks of SO_2 and NO_2 sampler were found to be 0.63 ppb and 0.49 ppb, respectively. Measured concentrations range from <LOD to 1.58 ppb for NO_2 and from <LOD to 0.44 ppb for SO_2. For ten species of VOCs investigated, on the other hand, most of compounds except for toluene and benzene could not be detected because of extremely low concentrations below the instrumental detection limits. Measured concentrations range from <LOD to 0.96ppb for toluene and from <LOD to 0.22 ppb for benzene. Although the concentrations of most gaseous contaminants investigated are observed to be very low, our results clearly show that anthropogenic emissions at King Sejong Station affect the concentrations of several of these compounds. The limited but valuable data presented in this study will be helpful to establish the systematic air monitoring system in the near future.

멀티미디어 인터넷 교육을 위한 최신 기술에 대한 연구

Transmitting voice and image via internet is very important technology for internet distance learning and there are only small amount of internet contents using this technology. But the internet transmission speed is still cannot afford the customer need, and the CODEC technology which compressing and extracting image and voice is not practically used, there are a little contents using this technology in the area of distance learning. The CODEC algorithm that have high compression ratio had already developed, but it is not enough to offer software only. It is disscused the expansion process of MPEG which is fundametals of voice and image compression and the technological characteristics and pros and cons of comercial software Real Player and Media Player which using MPEG.

The purpose of this study was to study the dimensions of the string phenomenon and the x and y axis line widths to select the optimal output conditions for 3D printers using the taguchi method. Four variables were derived through a pre-experiment, and a total of two experiments were conducted randomly in the order of 27 combinations of experimental conditions using an orthogonal arrangement table. The optimal conditions for the string phenomenon are 85% extrusion amount, 200mm/s, 0.2mm layer height, and output temperature 180 degrees. Optimal conditions for line width x were extrusion amount 100%, moving speed 200mm/s, layer height 0.2mm, output temperature 220° line width dimensions y, extrusion amount 85%, moving speed 150mm/s, layer height 0.25mm, output temperature 220°, and subsequent experiments showed optimum extrusion amount 90%, moving speed 200mm/s, output temperature 0.15mm, layer height.

A breathalyzer was modeled using the Arduino's mq3 sensor, and blood alcohol concentration was measured according to various types of drinking. The purpose of this study is to present an alternative to a safe drinking culture by analyzing the correlation of each variable through the measurement of blood alcohol concentration in the twenties. Alcohol consumption was measured based on soju. As a result of analyzing the measurement data, it was confirmed that height, drinking capacity, smoking, eating, and sleeping were correlated with blood alcohol concentration.
