The nondestructive testing using ultrasonic pulse-echo data is an effective test methodology esperially for metal structure. Typically, the ultrasonic pulse-echo data is processed and the results are shown in A-scan, B-scan or C-scan formats. Upon viewing B-scan and C-scan data the viewer is able to identify the location of faults as well as their rough dimension. In this paper, we evaluate the applicability of various 3-D visualization methods frequently used in medical imaging, namely, surface rendering (SR), volume rendering (VR) and maximum intensity projection (MIP), for nondestructive testing purposes. Such 3-D visualization of ultrasonic pulse-echo data enables easier identification of the location and dimension of faults more accurately.

One of the ultimate purpose in speech recognition is to recognize all of the arbitrary natural-sentences spoken by arbitrary speaker under any adverse environments. We review the theoretical and experimental foundations of the method, discuss the relationship with auditory perception, and extend to combination of additive noise and convolutional noise. This paper describes that performance comparision of the preprocessing schemes are applied to speech recognition in the adverse environments. Also some experiments of speech recognition are performed for department name of twenty-two that are pronounced one times by fifty Korean adults. The results show an application of the RASTA technique to speech enhancement.

The characteristic of the steady two-dimensional supersonic flow with condensation along a wavy wall of small amplitude in channel is investigated through the direct marching method of characteristics. The very complex problem that may appear where the overlapping of the same family charateristics occurs, can be satisfactorily solved by means of the modified method suggested by Zucrow. In the present study for the case of supersonic moist air flow, the dependency of location of formation and reflection of oblique shock wave generated by the wavy wall, and distributions of flow properties, on the relative humidity and temperature at the entrance of wavy wall is clarified by plots of frozen Mach number and iso-flow properties. Also, it is confirmed that the wavy wall plays an important key role in the formation of oblique shock wave, and that the effect of condensation on the flow field appears apparently.

The characteristics of the Prandtl-Meyer expansion of supersonic flow with condensation through a channel with a small amplitude wavy wall are investigated experimentally. In the present study, for the case of moist air flow in the type of indraft supersonic wind tunnel, the dependency of formation and reflection locations of the oblique shock wave and the distribution of flow properties are clarified by flow visualization and pressure measurement with the variation of the specific humidity and temperature at the entrance of the wavy wall and the attack angle of the wavy wall to the main stream. Also, we confirm that the wavy wall plays an important key role in the formatio of oblique shock wave, and that the effect of condensation on the flow field appears apparently.

This study was conducted to investigate the relationship between general characteristics and the eating-out behaviors of 643 male/female industrial workers. The results of the study was summarized as follows. 1. The frequency rate of eating-out was higher for male than female, college graduates than high school graduates, high income earner than low income earner, and unmarried than married(p<0.05). 2. Average cost for eating-out was higher for male than female, for high educated and high income earner than low educated person. Age, married or not, personal health conditions and BMI, however, didn't make any difference in the average cost for eating-out. 3. Reasons for eating-out was very different due to gender, age, degree of education, income rate, married or not, BMI(p<0.05) but basically eating-out was due to get together with friends or colleagues. Also, people who thought they were not in good health answered that they did not eat-out in any conditions. Overweighted people ate out more often than normal or under-weighted people. 4. The method in gathering information about eating-out was different according to the level of education and whether married or not. On the other hand, gender, age, income rate, personal health condition and BMI did not make a big difference in its method. However, most people who participated in the survey gathered information from people around them, such as friends/colleagues. 5. Taste was the most important factor in deciding the actual eating-out restaurant among the respondents and gender, age, level of education, married or not also made significant differences (p<0.05). 6. Besides personal health conditions and BMI, all the general characteristics including age made significant differences in selecting the most frequently visited restaurant . 7. Besides the personal health conditions, the transportation vehicle was different due to gender, age, level of education, income rate, married or not and BMI. As seen from the results, the eating-out behaviors mostly differed due to general characteristics. In order to searching for a new eating-out market, the general characteristics and the trend of the target customers has to be analyzed to activate the eating-out industry. In addition, the need for highly nutritional food with low calorific value has to be emphasized along with the taste.

Abstract-In order to investigate the pharmacological properties of New Wonbang Woohwangchungsimwon Liquid (NSCL), effects of Wonbang Woohwangchungsimwon Liquid (SCL) and NSCL were compared. In isolated rat aorta, NSCL and SCL showed the relaxation of blood vessels in maximum contractile response to phenylephrine (10^-6 M) regardless to intact endothelium or denuded rings of the rat aorta. Furthermore, the presences of the inhibitor of NO synthase and guanylate cyclase did not affect the relaxing effect of NSCL and SCL. NSCL and SCL inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs), NSCL and SCL significantly decreased heart rate. NSCL and SCL, at high doses, had a negative inotropic effect that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In excised guinea-pig papillary muscle, NSCL and SCL had no effects on parameters of action potential such as resting membrane potential, action potential amplitude, APD_90 and V_max at low doses, whereas inhibited the cardiac contractility at high doses. These results suggested that NSCL and SCL have weak cardiovascular effects with relaxation of blood vessels and decrease of heart rate, and that this effect is no significant differences between cardiovascular effects of two preparations.

Purpose: We have evaluated the compliance of hormone replacement therapy. Method: There are 185 climacteric women who are divided into three groups (Group I, Group II, Group III). Group I is given conjugated equine estrogen(CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate(MPA, 5mg, day 1-12). Group II is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 2.5mg, day 1-30), Group III is given only conjugated equine estrogen(CEE, 0.625mg, day 1-30). Results: 1) The compliance rate of hormone replacement therapy during three months is 77.9% including each Group I : 77.7%, Group Ⅱ : 76.1%, Group Ⅲ :80.4%. 2) The compliance rate of hormone replacement therapy during six months is 60.7% including each Group Ⅰ:52.9%, Group Ⅱ: 56.4%, Group Ⅲ: 79.5%. 3) The compliance rate of hormone replacement therapy during nine months is 49.7% including each Group Ⅰ: 45.5%, Group Ⅱ:41.7%, Group Ⅲ: 64.3%. 4) The compliance rate of hormone replacement therapy during a year is 44.4% including each Group Ⅰ: 40.2%, Group Ⅱ:35.3%, Group Ⅲ: 59.5%. Conclusion : It is vital that we maximize compliance if patients are to receive the full benefits from hormone replacement therapy. We think that physicians who prescribe hormone replacement therapy for climacteric women should enough explain the purpose, risks, and side effect of treatment for maximizing compliance of hormone replacement therapy.
