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.

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.

Thermogravimetric analysis and pyrolysis experiment were used as studying the effent of conversional level on the thermal degradation of HDPE. The wide conversional range in this work encompassed a change in the degradation mechanism. To accommodate this mechanism change, the data were treated as a pseudo first-order reaction. It was observed that the data conformed to a first-order fit at conversional range of 0.05∼0.98 with an activation energy of 376 kJ/mol. The lower activation energy occurring at lower conversion (0.01∼0.05) is attributed to scission of 'weak links' in macromolecles. The higher activation energy was similar to the carbon-carbon bond dissociation energy and is associated with random scission throughout backbone chain. The lower the conversional level, the more abundant the paraffinic hydrocarbon in product. To what extent this finding are influenced by limitation of terminate reaction of radicals.

TAGUCHI 방법을 활용한 3D프린터의 최적출력조건 선정에 관한 연구

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.

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.

Background : The function of p53 protein was known to accelerate the apoptosis, but bcl-2 protein was known to suppress the apoptosis. The overexpression of p53 and bcl-2 proteins has been reported in many malignant tumors. Although the mechanism of tumorgenesis of the p53 and bcl-2 protein took hasnot been proved, bcl-2 positive tumors contrast to p53, appeared to have good prognosis. The expression pattern of p53 and bcl-2 in epidermal tumors has not been well known. The author analyzed immunohistochemical expression of p53 and bcl-2 protein and investigated the role of p53 and bcl-2 protein in the developing tumors of epidermal origin. Method : 15 cases of squamous cell carcinoma, 20 cases of basal cell carcinoma, 10 cases of keratoacanthoma and 6 cases of Bowen's disease were stained immunohistochemically stain with anti p53 and anti bcl-2 monoclonal antibody. Results : 1. In squamous cell carcinoma, the reaction of p53 was positive in 13 cases(86%) and the stain pattern showed more intensive reaction in poorly differentiated cells in the same tumor. bcl-2 showed negative in all cases of squamous cell carcinoma(0%). 2. In basal cell carcinoma, the reaction of p53 was positive in 10 cases (50%). The positive cells were mainly observed in squamous metaplastic portion, but the reaction was weak. bcl-2 showed positive in all cases of basal cell carcinoma (100%) and the reaction was strong. 3. In keratoacanthoma, p53 was positive in 7 cases (70%). The positive cells were mainly observed in the cells around the basement membrane. This finding suggested that p53 positive basal cells were programmed to become keratoacanthoma. bcl-2 was negative in all 10 cases of keratoacanthoma. (0%) In some cases, bcl-2 positive cells were observed around the basement membrane in some cases., which were negative to p53 This finding suggested that the existence of these bcl-2 positive cells were related to the prognosis of keratoacanthoma. 4. In Bowen's disease, p53 was positive in 5 cases ( 83% ) and the reaction was strong, so the tumor cells in Bowen's disease appeared to be poorly differentiated type. bcl-2 was negative in all 6 cases ( 0% ) of Bowen's disease, but bcl-2 positive cells were observed in the basement membrane in some cases.

The thermal degradation of polyethylene, polypropylene alone an their mixture into oil and gas products has been carried out at different reaction conditions. The effect of various parameters such as temperatures, space velocity, mixing ratio on the yield and composition of the oil recovery for these polymers at different reaction temperature. In polyethylene-polypropylene mixtures, the more polypropylene is added, the more rate of degradation of PE and conversion of PE/PP mixture increase at a lower temperature than that of PE alone. It is proposed that this enhancement is due to the free radical from polypropylene, in which can form free radical from polyethylene a lower temperature.

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.
