Objectives : This trial were conducted to evaluate the efficacy and adverse events of Bofutsusho-san(BTS) and Boiogiot-tang(BOT) by oriental obesity pattern identification on obese subjects, as compared to placebo. Methods : 166 subjects(body mass index ${\geq}25kg/m^2$) were recruited and randomized to receive BT(n=55), FH(n=55) or placebo(n=56) for 8 weeks. Anthropometric factors, serum lipid, glucose, blood pressure(BP), pulse rate, resting metabolic rate and oriental obesity pattern identification questionnaire were measured at baseline and 8 weeks. Adverse events and safety outcome variables were also checked during trials. Results : The frequency of top-scored oriental obesity pattern was ordered by indigestion(食積) > stagnation of the liver qi(肝鬱) > yang deficiency(陽虛) > spleen deficiency(脾虛) > phlegm(痰飮) > blood stasis(瘀血) in subjects. BTS group significantly decreased body weight, body mass index(BMI), waist circumference(WC), body fat mass, total cholesterol and HDL-cholesterol in stagnation of the liver qi(肝鬱) and WC in indigestion(食積). BOT group showed significant decrease of body weight, BMI, WC, and body fat mass in indigestion(食積) not in deficiency(虛症). Adverse events were reported most frequently in yang deficiency(陽虛) by BT group and stagnation of the liver qi(肝鬱) by BOT group. Conclusions : Bofu-tsusho-san was effective in treating obesity with stagnation of the liver qi(肝鬱). Obesity pattern identification could be a useful diagnostic tool predicting treatment effects and adverse events.

In order to develope the porous alumina ceramics with high strength, the pore characteristics and compressive strength were investigated in terms of relation to the conditions of spark-plasma sintering and the contents of graphite as a pore precursor. Porous alumina bodies were successfully prepared by spark-plasma sintering and burning out graphite in air. High porous bodies were fabricated by sintering at 1000${\circ}C$ for 3 min under a pressure of 30 MPa, heating rate of 80${\circ}C$/min and on-off pulse type of 12:2. For example, alumina bodies prepared by the addition of 10∼30 vol% graphite showed high porosity of 50∼57%. Also, the open porosity increased with graphite content. The relationship between pore characteristics and graphite contents could be explained by percolation model depending on cluster number and size. Porous alumina bodies prepared by the addition of 10∼30 vol% graphite showed the high compressive strength of 55∼200 MPa. This great improvement in strength was considered to be mainly due to the spark-plasma discharges and the self-heating action between particles.

In this paper, we measured the variations of radon concentrations in groundwater using low-level Liquid Scintillation Counter (LSC), an instrument for analyzing the alpha and beta radionuclides at its 10 sites around the Kumjung-Gu, north-western of Busan. Optimization of Pulse Shape Analyzer (PSA) to determinate the highest value of figure of merit (FM) was decided using Quantulus 1200 LSC with radium-226 source, the optimal PSA level was shown in the range of 100 to 110. The results show that the Minimum Detectable Activity (MDA) of radon concentrations is 0.61 $Bq{\cdot}L^{-1}$ for 20 minutes in PSA level. We find that the average radon concentration in groundwater is high in granitic rock area and low in volcanic rock area. (Biotite granite : 191.39 $Bq{\cdot}L^{-1}$, Micro graphic granite : 141.88 $Bq{\cdot}L^{-1}$, Adamellite : 92.94 $Bq{\cdot}L^{-1}$, Andesite (volcanic) : 35.35 $Bq{\cdot}L^{-1}$). No significant seasonal variation pattern is observed from the long-term variation analysis from 10 selected sites. We have not seen the significant correlation of radon concentration to groundwater temperature, atmospheric temperature, atmospheric pressure and rainfall. The concentration variation is probably caused by more complex factors and processes.

This was an open trial to evaluate the efficacy and safety of moclobemide twice daily for treatment of Korean patients with major depressive disorder(DSM-III-R). The duration of the trial was 6 weeks with the initial dose of moclobemide being fixed lor the first two weeks at 300mg/day(150mg twice daily, each token after morning and evening meals). Thereafter, when necessary, the dose was allowed to increase to 600mg/day or decrease to 150mg/day according to the seventy of the depression and/or the tolerability of the drug. Hypnotics and/or sedatives from a benzodiazepine group could be concomitantly administered at usual dosage. Patients were assessed at baseline and at days 14, 28 and 42. Efficacy was primarily judged on the Hamilton Rating Scale for Depression(HAM-D) and Beck Depression Inventory(BDI). Patients had to score at least 17 respectively an both scales to enter the trial. Secondary efficacy parameters included Clinical Global Impression(CGI) for severity of illness and improvement. Safety and tolerability were judged on reported adverse events, vital signs and laboratory parameters. In addition, there was a series of questions and assessments for the psychiatrists and patients to complete at the end of the trial Twenty nine patients completing trial were included in the analysis of efficacy : of thirty one patients participating in the safety and tolerability analysis, those who withdraw voluntarily without particular reasons or violated the treatment schedule were not included. The efficacies as determined by HAM-D, BDI or CGI were found to be significant compared to baseline. The number of responders defined as patients with a total score of 10 or less or with a total score of 50% or less of the baseline score on HAM-D and BDI were 17(59%) and 18(62%) respectively. Regarding safety and tolerability, nine patients(29%) reported mild adverse events probably related to moclobemide : of these one patient dropped out because of poor tolerability : however, there were no appreciable changes in blood pressure, pulse rate, body weight or laboratory parameters for all patients over the trial period. Furthermore, the physicians' and patients' opinions at final evaluation showed that moclabemide has a good antidepressant effect as well as a favorable tolerability. In conclusion, a twice-daily dosage schedule with maclobemide is recommendable for the treatment of Korean patients with major depressive disorder since its efficacy and safety were demonstrated in this study.

The purpose of this study were to evaluate the effect on the reversion of sedation induced by midazolam with flumazenil and to determine the plasma concentration of flumazenil according to the method of administration. Intranasal and intravenous flumazenil were administered to sedated health volunteers aged from 23 to 25 years, in doses typical of those used clinically to induce sedation with midazolam and for reversal with flumazenil. Objective assessment for degree of sedation and vital signs, plasma concentration were made for 2 hours period. 1. Systolic and diastolic blood pressure, $SpO_2$ were not changed by adminstration of flumazenil in sedated subject with midazolam, but pulse rate was increased temporarily. 2. Flumazenil showed the reversal of the sedative effect induced by midazolam regardless of administration methods. But intravenous administration showed more effect on the degree and the duration of reversion than intranasal administration with the exception of on set time. 3. Peak plasma concentration of flumazenil administered by intranasal route reached after 2 min and that of flumazenil administered by intravenous route was 4 min. Thus uptake of flumazenil did not showed any difference in accordance with the adminstration route. 4. Administration of flumazenil resulted in the temporary increase of midazolam plasma concentration.

In recent years, concern has been raised about the technique of controlling electrical breakdown by using laser in many fields. Especially, laser has attracted much attention in the Electro-Discharge Machining(EDM) because of its many rrents. 1berefore, this research has been perfonred to obtain fundarrental data for the discharge guide technology by a pulsed Nd:YAG laser which can be awJied to discharge processing machining. 1be experilnnts of laser-guided de discharge have been carried out at low air pressure ranging from 0.2 to 20 torr. The minimum laser-guided de discharge voltage $V_{G.min}$ at the given pressures P and distances d between an anode and a cathode was rreasured It is found that $V_{G.min}$ is much lower than the natural discharge voltage $V_{ND}$, and the values of VGrrin and $V_{ND}$ as a function of P.d has a similar tendency. The laser output energy $E_{out}$ decreases with input pulse duration $t_p$ increasing, and the rrore the value of $t_p$ increases, the higher that of V$V_{G.min}$ is obtained because the number of photons N decreases with $t_p$ increasing. In addition, the laser-guided de discharge range and the discharge guide characteristics as laser outpIt $E_{out}$ was investigated.igated.

This paper presents the communication performance for the radiation pattern reconfigurable antenna in the wearable device measuring bio signal (temperature, blood pressure, pulse etc.) of human body. The operational frequency is 2.4 - 2.5 GHz, which covers Bluetooth communication bandwidth. The maximum gain of the antennas is 1.96 dBi. The proposed antenna is efficiently transmitting and receiving signal by generating two opposite beam directions using two RF switches (PIN diode). Also, we investigated how radiation pattern changes according to three angles ($30^{\circ}$, $90^{\circ}$, $150^{\circ}$) of Top Loading. In this paper, we measured and compared the SNR (Signal-to-Noise Ratio) and BER (Bit Error Rate) performances of the proposed antennas in the condition between an ideal environment of anechoic chamber and smart house existing practical electromagnetic interferences (Universal Software Radio Peripheral, USRP). Throughout the comparing the results of the measurement of two cases, we found that the SNR is degraded over 5dB in average and BER is increased over ten times in maximum, therefore, it is confirmed that the error rate of receiving signal is increased. The measured results of SNR and BER value in this paper able to expect the performance degrading by the interference from the electromagnetic devices.

The purpose of this study is to determine the effects of guided imagery activities using music on both mood states and physiological responses of psychiatric inpatients. The experimental group was consisted of 27 psychiatric patients participating in the guided imagery activities using music for 11 minutes. Also, the control group was formed with 27 psychiatric patients with non-musical intervention. Mood states, blood pressure, pulse and skin temperature were checked before and after session. We could see the significant difference in the score of five areas-tension, depression, anger, vigor, fatigue-showed most differences in score. Also, the score of skin temperature of both experimental group and between two groups showed significant differences, too. Therefore, we can conclude that these results were showing that guided imagery activities using music was an effective nursing intervention method for altering mood state of psychiatric patients. Besides, it seemed to have physiological impact to make patients relax tension backed up by change of skin temperature.
