Ultrasonic nondestructive testing is a versatile an successful technique that can be applied to a wide variety of material analysis applications. The state-of art techology of sensors, microprocessors, and methods for signal analysis hs been promising new possiblilities for the application of ultrasonic techniques to non-destructive and non-hazardous tstings. Ultrasonic material analysis is based on a simple principle of physics. That is, the motion of a wave is affected by the medium through which it travels. Thus, changes in one or more of four measureable parameters associated with the passage of a elastic wave through a material - time of flight, attenuation, scattering, and frequency content - would be correlated with changes in physical properties such as hardness, elastic modulus, density, homogeneity or particle size and structure. Ultrasonic techniques can be applied to various biosystems such as food, agricultural products and biological materials, owing to their nondestructive nature. in this paper, the principle of ultrasonic technique was briefly described and its applications to biosystems were reviewed.

It is very important to detect the bearing defects in rotating machinery since the critical failure of bearing cause a machinery shutdown. However it is difficult to detect the vibration signal resulting from the initial defects of bearing because of the high level of broadband noise. A signal processing technique, called the adaptive line enhancer(ALE) as one of adaptive filter, is studied in this work. This technique is to eliminate broadband noise without a prior knowledge of the noise and signal characteristics. Also we propose the optimal methods for selecting the three main ALE parameters such as correlation length, filter order and adaptation constant used in the adaptative process. Vibration signals for three abnormal bearings, including inner and outer raceways and ball defects, were acquired from Anderon(angular derivative of radius on)meter. The experimental results showed that the proposed technique can reliably detect the bearing defective signals masked by broadband noise.

The Purpose of this study is to analyzing the developing process of physique during the 12 years regression equation standard body weight according to the age and body height and also we analyzed the distribution status of normal body weight and obesity weight in 17-year old high school students. A total of 1,423 samples(male:723, female: 701, born between March 1, 1977∼February 28, 1978) and the students who were randomly selected in big city of north of Jeola province, The result of our analysis are as follows: 1.Measurement of Physique ①The steady growth showen 14 year of male and 12-year of female in body height, 14-year of male and 13-year of female In body weight, 15-year of male and 13-year of female In chest-girth, since then the growth and development linear curve is more showness. ②During the 12year of school age, the rate of growth were 55.12cm(47.4%) of male 44.80cm(38.9%) of female in body height 43.59(214.5%) of male, 35.20kg(180.8%) female in body weight and 3.83cm (55.48%) of male, 28.11cm(50.70%) of female in chest girth. ③The age of maximum rapids growth were 12∼13 years old(7.36 ± 2.52cm) of male 10∼ 11years old (6.81± 1.88cm) of female In body height, 12∼13years old(6.14±3.37kg) of male, 11∼12 years old(5.49±2.67kg) in body weight and the chest-girth were 13∼14years old(4.34± 3.20cm) in male, 11∼12 years old(5.01 ± 3.80cm) in female. ④The age of cross over between male and female were 9.7∼ 11.7 years old in body height, 11.5∼ 13.5 years old in chest-girth and there is on cross over in body weight. ⑤The body height of 17-year old was 171.68∼5.56cm in mate and 159.92±4.85cm in female, body weight was 63.91±8.89kg in male and 54.67±6.74kg in female and the chest-girth was 89.20±5.94cm in male 83.55 ± 5.27cm in female. ⑥Physical growth and development was more remarkable improvement than 1980' Physique especially the age of adolescence. 2.Standard body weight by regression equation ①Correlation coefficient of r=0.469-0.760 between body height and body weight in male and r=0.347-0.793 in female. ②Regression equation of standard body weight were found in 17-year old and the equation were y =0.749X+64.791 in male, y=0.484X+22.800 in female. ③The distribution of normal body weight were 63.1% in male and 76.2% in female, over weight were 10.4% in male and 9.3% in female and the obesity weight were 6.9% in male and 3.4% in female.

This study summarizes the results of tests on 18 Two-slab push out specimens. The main purpose of the investigation was to evaluate the capacity and behavior of stud shear connectors embedded in the normal concrete(F_c=173∼295㎏/㎠). Two different diameters(Φ16mm,Φ13mm) of steel shear connectors welded on T-shpaed steel were used for push out specimens. The following conclusions were drawn from this study. 1. The shear strength(q_u) of stud shear connectors embedded in concrete was influenced by the cross sectional area of the steel shear connector(A_s), concrete design strength(F_c) and elastic modulus of the concrete(E_c). The emperical function described the test results. q_u = 0.3A_s√FcEc 2. The maximum loads in this study were reached at slips varing from 1.5mm to 4.0mm 3. The webs of T-shaped steels welded by the steel shear connectors were safe under t≥d/2. Where t is the thickness of the webs, d, the diameter of stud shear connector.

The mechanical joint method is expected to take an important part in the P.C. construction methods. Grout-filled splice sleeve system is used for connecting reinforced concrete column to column and wall to wall in the construction field. This is an experimental study to clarify the bond capacity to be generated between mortar(660kgf/cm2-803kgf/cm2) and reinforcing bar in the grout-filled splice sleeve system. The developed length in the splice sleeve is 4.2d~6.2d Following main conclusions are obtained: (1) Grout-filled splice sleeve system satisfies the structural performance. (2) When comparing the experiment result with existing sleeve design formula on the bond capacity, existing formula is rather safer, but it is considered necessary to present more exact sleeve formula through more close experiment.

Manganese slimes from zinc refinery electrolytic cell contain 59.94% MnO_2. The recovery process of MnO_2 from the slimes consists essentially of five steps, i.e., roasting of the slimes, dissolution of the manganese, removal of iron, electrolytic synthesis on MnO_2 from MnSO_4 solution, and preparation of finished MnO_2. Also we report here the optimum conditions of the recovery process of MnO_2 from mangaanese slimes. The crystal structure of MnO_2 product is γ-type.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.
