In, order to find out how is swimming affect to housewife who has health satisfaction and confidence of daily life. so I surveyed 300 certain housewife group, they have been swimming in sports center. I adapted 287 numbers. except 13 (they responsed unproper answer). I divided them according to participate period (per month), how often (per week), motivation. I got average, difference by spsswin 10.0 and find out difference of them by one-way ANOVA As a result, it follows like this. 1. There is a difference swimming and participation period but no difference how often they engaged. 2. There is no difference about period, how often motivation. From this I concluded that swimming affect certainly their health life satisfaction but it didn't affect confidence. So we should plan sport program which will affect their confidence.

A synchronization is important element not only wire communication but also wireless communication. Especially, In SS(Spread Spectrum) communication method used GPS(Global Positioning System) synchronization is more important. A synchronous oscillator(SO) is a network which synchronizes, tracks, filter, amplifies and divides (if necessary) in a single process. Without an input signal, the SO is a free-running oscillator, oscillating at a frequency w??, but phase changes 180。 within tracking range of SO. Therefore CPSO was used for this problem. The coherent phase synchronous oscillator(CPSO) is created by adding two external loops to the SO and has a wider tracking bandwidth and a zero-offset phase response (coherent) while maintaining the SO properties of high signal-to-rejection and fast frequency acquisition times. Therefore phase between input signal and output signal is synchronized. In this paper, GPS data recovery circuit has applied CPSO using front reference characters and has certified and excellent data recovery capability.

Recently, there has been much interest in utilizing chaotic circuits to implement a secure communication. Although Chua's circuit is the simplest chaotic circuit, it has complex chaotic dynamic porperties. The modified Chua's circuit has two additional components more than Chua's cirecuit and makes the circuit equations become fore-dimensional instead of three-dimensional, it makes Chua's circuit more flexible. In this paper, we use two modified Chua's oscillators to simulation on the chaos control and synchronizaion. The simulation results show that the modified Chua's oscillator has good chaotic control and sunchronization. And we have successfully carried out the basic esperiment on the chaotic secure communication.

A 8 year-old, 5.8kg, intact female shih-tzu dog with depression, anorexia, pale mucous membrane was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. A diagnosis of the patient was made based on history taking, Physical examination, laboratory examination, radiography and ultrasonography. Blood and blood chemical examination revealed that PCV was 95% and total bilirubin was increased. Autoagglutination was observed and many spherocytes were found on Diff-Quik stained blood smear. Direct Coombs' test result was positive and marked hepatomegaly was found on the radiograph. Immune-mediated hemolytic anemia was diagnosed by above on these findings. No transfusion, and immunosuppressive agent with azathioprine was administrated. PCV increased from 9.5% to 15.5% 4 days later and to 34.9% 19 days later. PCV is 43.2% and azathioprine is administered every 3 weeks to date.

Twelve clinically healthy mongrel dogs were used to clarify the possibility of general analgesia induction by lidocaine aquapuncture to auricular root area in the present study. The experimental animals were devided into control (6 heads) and experimental groups (6 heads), respectively. Physiological salines (3 ml/kg) were injected into both auricular root areas in control group. Lidocaine hydrochlorides (3 ml/kg) were injected into both auricular root areas in experimental group. Superficial pain, the changes of vital signs and blood leukocytes, and PCV were examined on pre, 5 min., 15 min., 30 min, and 60 min. after injection in control and experimental groups, respectively. Analgesia was not detected at all in control group, however, all experimental animals were recumbent and analgesia was generally detected in the auricles, noses, dorsal parts, ventral areas, limbs and tails from 5 to 30 minutes after injection with lidocaine hydrochloride into auricular root areas in experimental group. As for the change of vital signs, body temperature showed decreasing tendency from 5 minutes after lidocaine injection in experimental group. Heart rates and respiration rates were increased on 5 minutes after lidocaine injection and then they showed decreasing tendency in experimental group. No significant difference were found among groups. As for the changes of hematological findings, the numbers of blood leukocytes were increased till 15 minutes after lidocaine injection and then they showed decreasing tendency. PCV values were increased on 5 minutes after lidocaine injection, and then they showed decreasing tendency. However, no significant differences were observed among groups. Considering the above findings, it was thought that general analgesia was possible by aquapuncture with lidocaine hydrochloride into auricular root areas and lidocaine aquapuncture didn’t affect so much to the changes of vital signs and blood.

Campbell Early(Vitis labruscana B.) grape shoot tips derived from cuttings were cultured on modified basal media of Murashige and Skoog(MS) differing in pH, nitrogen strength, N-source(NO3 - N and NH4- N), Cl- and SO42-, and their responses to nutrient uptake were investigated. 1.Optimal pH for mineral absorption except P was 5.0. 2.Maximum nutrient uptake was obtained with 0.50 - (0.50N) to 0.75-fold nitrogen (0.75 N) media. 3.Increase in total mineral contents of P, K, Ca, and Mg in shoot mass derived from one initial shoot tip was proportional to NO3-N level while N absorption was enhanced with 75 : 25 to 50 : 50(NO3-N : NH4-N) media. 4.MS medium with both Cl- and SO42- was favorable for N uptake. Absorption of P, K, and Mg was greater with the media composed only with SO42-, while Ca uptake was stimulated with Cl- media.

Sarcoidosis is a multisystem granulomatous disease of unknown cause, characterized by enhanced cellular immune process at the sites of involvement. Three Cases of sarcoidosis involving vilateral hilar lymph nodes, skin and lungs were presented. Each case was confirmed by characteristic non-caseating granuloma in biopsied thoracic lymph nodes and skin. They had abonormal pulmonary function test, elevated serum angiotensin converting enzyme, hilar and mediastinal lymphadenopathy and compatible clinincal features of sarcoidosis.

During the past five years, there has been tremendous interest worldwide in the possibility of exploiting chaos in wideband communication systems. Many different demodulation techniques have been proposed up to date. They can be divided into two basic categories. In the first approach, like the conventional coherent demodulation techniques, the chaotic signal has to be recovered from the received noisy signal by synchronization. However, the chaotic synchronization techniques published to data are so sensitive to the channel noise and distortion that these techniques can not be used in radio communications. In the second approach, the demodulation is carried out nonsynchronization. This paper surveys the different chaotic communication techniques that can be implemented nonsynchronization and compares the threshold and BER of the different methods. Finally, FM-DCSK is introduced the first step for apply to wideband chaos digital CDMA, where the data is not limited by the inherent nonperiodic property of the chaotic signal.
