Abuse liability of ephedrine was investigated by measurement of locomotor activity and self-administration in Sprague-Dawley rats. Locomotor activity was determined in rats treated with 3, 10 and 30 mg/kg ephedrine for 14 days. Self-administration by ephedrine (0.23, 1 and 2.3 mg/kg) was examined in food-trained rats. We also examined effect of dopamine receptor antagonist (spiperone, $30{\;}\mu\textrm{g}/kg$) on the ephedrine-induced response of self-administration. Body weight was not statistically difference between control and ephedrine treatment group, but locomotor activity was dose-dependently increased. Self-administration for ephedrine was decreased in the early response (day 1 and 2) but the response was increased by higher dose of ephedrine. Self-administration was decreased by dopamine receptor antagonist (spiperone). These data showed that ephedrine increased locomotor activity and induced response of self-administration, and the effects of ephedrine were partially related to the dopaminergic system, which suggest the ephedrine may have abuse liability.

Self-powered sensors play an important role in everyday life, and they cover a wide range of topics. These sensors are meant to measure the amount of relevant motion and transform the biomechanical activities into electrical signals using triboelectric nanogenerators (TENGs) since they are sensitive to external stimuli such as pressure, temperature, wetness, and motion. The present advancement of TENGs-based self-powered wearable, implantable, and patchable sensors for healthcare monitoring, human body motion, and medication delivery systems was carefully emphasized in this study. The use of TENG technology to generate electrical energy in real-time using self-powered sensors has been the topic of considerable research among various leading scholars. TENGs have been used in a variety of applications, including biomedical and healthcare physical sensors, wearable devices, biomedical, human-machine interface, chemical and environmental monitoring, smart traffic, smart cities, robotics, and fiber and fabric sensors, among others, as efficient mechanical-to-electric energy conversion technologies. In this evaluation, the progress accomplished by TENG in several areas is extensively reviewed. There will be a discussion on the future of self-powered sensors.

The purpose of this study is to empirically analyze whether or not, if a community social service center was affiliated with a governing body running other community social service centers, the center would have better organizational performance in comparing to an independently running center. Data was collected from a nationwide mailed and self-administered survey, which 237 centers out of 343 community social service centers responded. Even if, the response rate was 72%, 218 centers were finally analyzed due to the weakness of reliability and incompleteness. By the way, measurement of organizational performance as the dependent variable has been substituted of the results of nationwide organizational evaluation project as the secondary data. One of findings is that 68% of 218 responding centers appeared to be affiliated with a governing body which running more than three other centers, while 41% being affiliated with a body which running more than five other centers. However, a logistic regression analysis which using organizational performance as the dependent variable, has failed to verify the hypothesis that a center which affiliated with a governing body running other centers has better organizational performance when comparing to an independent center. The researcher assumes that a part of governing bodies has better performance and improves competitiveness while the other larger part of them pursues simple organizational growth. Thus, this situation made that the overall evaluation of being affiliated with a large governing body was not positive.

The purpose of this study was to examine which factors among addiction buying behavior had been affected by body image. 235 female college students were surveyed for this study. For data analysis, descriptive statistics, $x^2$-test, multiple regression were used. As the results, generally there were significantly correlated among body image, diet addiction, binge eating, cosmetic surgery addiction, compulsive behavior and shoplift tendencies. Multiple regression results revealed that diet addiction, cosmetic surgery addiction, binge eating accounted for 34.8% of the explained variance in weight obsession. Also, regression results indicated that cosmetic surgery addiction, self-esteem, and diet addiction, and cosmetic surgery obession accounted for 20.4% of the explained variance in appearance orientation. Finally, regression results pointed out that self-esteem and diet obession accounted 22.3% of the explained variance in appearance evaluation. Based on these results, fashion marketing strategies would be suggested.

If we may practice the nutrition education planned on the basis which carefully grasped the inappropriate behavioral determinants of middle-school students, it might be an effective method achieving the change in perception and behavior improving the distorted perception about the ideal body shape, so we are to suggest the 8 week program of body shape perception improvement for successful nutrition education as follows. The body shape perception improvement program is a step-by-step group consulting program. At the introduction stage, we let them understand the meaning of true beauty and body change of teenage period and forming of sexual identity. At the stage of perception conversion, we let them have the opportunity to observe the status of body perception of the teenager and self-observation. At the stage of correction, we let them criticize the distorted body image in the society with mass media at the same time with the self-reflection. At the stage of maintenance and evaluation, we suggested the behavior guidance while preparing it. Setting this as the basis, we applied the contents such as the evaluations through cultural sharing events making somethings while directly participating. As the target groups to practice education were middle school students, we considered the learning level and behavioral features of the middle school students, and composed the programs including the methods such as role play, watching real things, media production, discussions and experiences. If the program of body shape perception improvement developed at this study could be utilized at the field of schools, the teenagers can change their ways of thought naturally avoiding the view about unified appearance rightly perceiving negative self-image that the teenagers can have and if the group consulting can be practiced regularly at each school, many students may experience the change in perception, so it might solicit the improvement of health of the families and local societies as well as that of the individual student.

Purpose: This study developed an integrated health management program for metabolic syndrome in psychiatric patients and examined its effects on self-efficacy, healthy lifestyle, physiological indicators, knowledge of metabolic syndrome, attitudes toward healthy behavior, and social support. Methods: A non-equivalent control group pretest posttest design was used. The participants were 65 psychiatric patients with metabolic syndrome in psychiatric rehabilitation centers, with 33 in the experimental group and 32 in the control group. The experimental group participants engaged in daily mobile application and walking exercises three times a week for more than 40 minutes over 8 weeks, while those in the control group were provided education booklets. The outcomes were measured using self-report questionnaires, anthropometrics, and blood analyses. Intervention effects were analyzed using the independent t-test, Mann-Whitney U test, ANCOVA, and Ranked ANCOVA. Results: The experimental group showed a significant increase in self-efficacy (F = 8.85, p = .004, η_p² = .13) and knowledge of metabolic syndrome (t = 2.60, p = .012, d = 0.60) compared to the control group. Additionally, the experimental group demonstrated a significant decrease in waist circumference (Z = - 2.34, p = .009, d = 0.58) and body mass index (Z = - 1.91, p = .028, d = 0.47) compared to the control group. Conclusion: The integrated health management program for psychiatric patients with metabolic syndrome is effective in improving self-efficacy and knowledge of metabolic syndrome and decreasing physiological indicators such as waist circumference and body mass index.

Experimental investigations were carried out on an Axi-symmetric Body Model fitted with Pump-jet Propulsor (PJP) in the Cavitation Tunnel at Naval Science and Technological Laboratory (NSTL). The tests were intended for evaluating the propulsion characteristics of the body and propulsor. The self propulsion point of the model for two configurations was determined after finding the corrections for tunnel blockage effects and differences in model length at zero trim. The results were found to match closely with the towing tank results. The rotor and stator torques also matched closely over full range of experiment. Further experiments were carried out on the body at $4.5^{\circ}$ angle of trim to investigate the propulsive performance and assess the operational difficulties in the sea. The results indicated an increase in resistance and decrease in rotor thrust; but the balance of torques between the rotor and stator was undisturbed, causing no concern to vehicle roll.
