The purpose of this study is to comparatively analyze the biochemical changes of the in-plasma non-nitrogen compounds between before and after the dahnjeon respiration training and thereby, determine the value of the dahnjeon respiration as aerobic exercise and its physiological effects. The results of this study can be summarized as follows; First, as a result of comparing the in-plasma glucose concentration between before and after the program, it was found that the concentrations were 121.38±10.06mg/dl and 119.25±9.75mg/dl, respectively, which was insignificant statistically. Nevertheless, the glucose concentration was lowered by the training program, although insignificantly. Second, as a result of comparing the triglyceride concentration between before and after the program, it was found that the concentrations were 154.63±7.61 mg/dl and 153.25±8.03mg/dl, respectively, which was significant statistically. Third, as a consequence of comparing the total cholesterol concentration between before and after the training program, it was found that the concentrations were 197.00±11.75mg/dl and 193.63±11.25mg/dl, respectively, which was also significant statistically. Fourth, as a result of comparing the HDL-C concentration between before and after the program, it was found that the concentrations were 53.25±7.09mg/dl and 54.50±6.95mg/dl, respectively, which was significant statistically, too. Fifth, as a result of comparing the LDL-C concentration between before and after the training program, it was found that the concentrations were 117.50±6.93mg/dl and 115.50±6.82mg/dl, respectively, which was also significant statistically. In conclusion, it was found through this study that after the dahnjeon respiration training, the in-body non-nitrogen compound concentrations has conspicuously lowered, which seemed to be very desirable to health. All these findings suggests that although the dahnjeon respiration training seems to be very static, it has an aerobic exercise effect. All in all, the dahnjeon respiration training which seems to be at once static and dynamic may be a good sports recommendable for the aging people.

Zine was electrodeposited in the zincate solution at the temperatures of 20 and 40℃ in range of current density from 0.5 to 8A/d㎡. The preferred orientaion changed from (11.0) to (11.0)+(11.2) texture with increasing cathode overpotential. The (11.0) preferred orientation was developed at low overpotential (790-1070mV), while the (11.0)+(11.2) texture at high overpotential (1050-1130mV). The surface of the deposits with (11.0) texture showed the smooth deposit of fine crystallite, while that with (11.0)+(11.2) was the smooth deposit of layer type. The cross-sectional microstractures of the deposits were the field orinted texture type of structure and granular one respectively.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

In the study on the fatigue strength and characteristics of fatigue of the low carbon steel which was heat-treated in five conditions. The specimens were smoothed and round-notched, and fatigued by rotating bending fatigue testing machine. The following results were obtained: 1) The fatigue strength of water-quenched specimen was the highest vaule, and these values were decresed orderly as follow, oil-quenched specimen, tempered specimen, no heat-treated specimen and furnace-cooled specimen. 2) The fatigue strength ratio of tempered specimen was between that of no heat-treated specimen and water-quenched specimen. 3) The hardness distribution in the micro area of structure was hardly equal to that of the full area of structure.

A design method for electrohydraulic servomechanism emphasized on the analysis of characteristics and selection method of servovalve and actuator which are very important components in designing the electrohydraulic servomechanism is summarized and suggested in systematic way. According to the design procedure of the proposed design method in this paper, the dynamic characteristics and accuracy of control system were analyzed using position control system of cylinder driving as a design example. The result of this analysis has shown that the proposed design method is very efficient for design of electrohydraulic servomechanism. The proposed method in this paper analyzed the characteristics of each component using linear approximation. Therefore, nonlinear characteristics and high frequency region should be considered in the case of strict design for higher accuracy.

A retrospective analysis by chart review of 130 cases of patients with suicidal attempt who visited emergency department of Dankook University Hospital from January 1998 to December 1998. The results were as follows ; 1. The ratio of patients with suicidal attempt to total patients who visited emergency department was 0.7%. The highest suicidal attempt rates were among aged 20-39. The gender ratio is similar. 2. Suicidal attempt were more common in summer, July, Friday, evening. 3. The most common place of suicidal attempt was home. 4. Drug ingestion was the most common method of suicidal attempt. Drug used for suicidal attempt were agricultural drug including organic phosphorus and carbamate, and therapeutic drug. 5. Common motives of suicidal attempt were marriage conflict, family conflict. 6. The intensity of will to die was more strong in old aged male. 7.

This paper presents a polishing expert system integrated with sensor information which can modify the polishing sequence and conditions initially determined by the system depending on the on-site polishing status. A practical system using AE sensor to detect the on-line polishing status is developed for the rotational polishing and the smoothly curved sur-face. Database and knowledge base for polishing processes are established by using the results of experiments and also expert's experience. Evaluations are performed for a die of headlight lamp by using both the sensor integrated expert sys-tem and the expert system without sensor. The test results show that the sensor integrated expert system provides more optimal polishing conditions since the proposed system takes advantage of the on-line sensor information.
