  • This study aimed to investigates the effects of self-assertiveness and appearance satisfaction on psychological well-being (personal growth, purpose in life, self acceptance, environmental mastery, autonomy and interpersonal relations), and find out if there exists any causal relationship among each variable in the process. For data collection, a questionnaire was administrated from April 23 to May 13, 2012 in the city of Gwangju, Korea. The subjects were women in their twenties and thirties. 359 women responded to it. The results were as follows. First, overall self assertiveness had positive effects on appearance satisfaction which, in turn, turned out to have overall positive effects. Second, the overall effects of self assertiveness on psychological well-being turned out to have positive effects. Third, overall appearance satisfaction had positive effects on psychological well being. Forth, the effects that self assertiveness had on psychological well-being mediated appearance satisfaction and appeared to be partly insignificant. The implications and the direction of this research should be discussed in the future study so that it can improve personal psychological well-being by finding out other variables aside from self assertiveness, appearance satisfaction.

  • Purpose : To observe changes in side effects and fatigue of the cancer patients receiving radiation therapy on the head/neck and the chest over a period from the start to the end of the therapy, and to analyze correlation between side effects and fatigue. Method : Twenty seven patients receiving radiation therapy 5 days per week for longer than 6 weeks participated in the present study. Fatigue was measured for when healthy, before-, and after-therapy. Side effects was surveyed by structured questionnaire on the last day of each therapy. Result : The results of this study were as follows. 1. Major side effects of the head/neck patients were skin irritation, change of taste, sore throat and xerostomia, while the chest patients experienced fatigue, skin irritation, anorexia, difficulty swallowing and cough increased with therapy. 2. Although fatigue was significantly changed for when healthy and before-therapy (F=60.25, p <.05) and also for before- and after-therapy, no statistical significance was demonstrated in fatigue of both the chest head/neck patients (p> .05). 3. Fatigue and side effects showed high correlation form the 4-th week with after the therapy Conclusion : The present results could be of great use to develop systematic intervention technique, leading to practical help for patients, since side effects and fatigue change to a large degree depending on the disease and the timing and technique of the therapy.

  • Objectives : This study was designed to investigate the effects of anti-oxidation of fractionated Pulsatilla koreana $N_{AKAI}$ (PK) extracts. And we examined to determine that a certain fractionated extract has the best anti-oxidative effects between the fractionated PK extracts. Methods : Anti-oxidative effects of fractionated PK extracts was measured by scavenging activities of DPPH, superoxide, nitric oxide (NO) and peroxynitrite radicals. And also scavenging activities of anti-oxidation in lipopolysaccharide (LPS)-treated RAW 264.7 cell was measured. After these examination, we determined a fraction that has best anti-oxidative effects. Results : Fractionated PK extracts inhibited radicals effectively. Also in RAW 264.7 cell, intracellular oxidation has inhibited by PK extracts. In these tests, ethyl acetate (EA) fraction has the best anti-oxidative effects among PK extracts. Conclusions : This results demonstrate that PK extracts exhibit anti-oxidative effects. And EA fraction has the best inhibition effects among the six fractions of PK.

  • Objective : This study was carried out to investigate protective effects of Pharmacopuncture Solutions (PSs) made by Carthmi Flos (CF), Cnidii Rhizoma (CR) and Astragali Radix (AR) on C6 glioma cells Methods : We investigated the effects of PSs on proliferation rates and types of C6 cells, and also investigated the effects on LDH release. In addition, protective effects of PSs on oxidative stress induced by hydrogen peroxide and SOD-like activities were also investigated. Results : PSs made by CF, CR and AR did not show cytotoxicity in various concentrations. CF-PS and AR-PS elevated levels of proliferation rates significantly. Treatment with CF-PS lowered level of LDH release in C6 cells. In addition, CF-PS and CR-PS showed protective effects on cell death induced by hydrogen peroxide respectively. Finally, CF-PS group showed high level of SOD-like activity compared to that in CR-PS group. Conclusion : These results suggest that CF-PS can accelerate proliferation of neuroglial cells, and has protective action against oxidative stress, which was involved in anti-oxidative effects such as SODlike activities. In addition, CR has protective effects against oxidative stress, and AR can accelerate proliferation of neuroglial cells.

  • In this paper the differential transformation method (DTM) is utilized for vibration and buckling analysis of nanotubes in thermal environment while considering the coupled surface and nonlocal effects. The Eringen's nonlocal elasticity theory takes into account the effect of small size while the Gurtin-Murdoch model is used to incorporate the surface effects (SE). The derived governing differential equations are solved by DTM which demonstrated to have high precision and computational efficiency in the vibration analysis of nanobeams. The detailed mathematical derivations are presented and numerical investigations are performed while the emphasis is placed on investigating the effect of thermal loading, small scale and surface effects, mode number, thickness ratio and boundary conditions on the normalized natural frequencies and critical buckling loads of the nanobeams in detail. The results show that the surface effects lead to an increase in natural frequency and critical buckling load of nanotubes. It is explicitly shown that the vibration and buckling of a nanotube is significantly influenced by these effects and the influence of thermal loadings and nonlocal effects are minimal.

  • Purpose: The influence of age on time preference is not identified in the usual cross-sectional analysis. This study aims to test whether age affects time preference after controlling for the effects of individual heterogeneity including cohort effects. Research design, data and methodology: Drawing on a nationally representative panel dataset of Indonesians, we estimate the effects of age on time preference after controlling for unobserved individual heterogeneity as well as potential cohort effects. We measure time preference exploiting information on two sets of multiple price lists: one for a one-year delay, and the other for a five-year delay. Results: When we controlled for time-invariant individual characteristics, including birth cohort effects in a fixed effects model, the older men and women were more patient in a linear fashion, particularly when the delay was longer. To highlight the importance of controlling for individual fixed effects, we repeated the specification without controlling for individual fixed effects in OLS or censored maximum likelihood regression; we found no relation between age and impatience in men or women and for a one or five-year delay. Conclusions: The older men and women are more patient, and time preferences are correlated with unobserved individual heterogeneity.

  • Objectives: The medicinal plants are believed to enhance the natural resistance of the body to infections. Some of the main constituents of the plant and derived materials such as, proteins, lectins and polysaccharides have anti-inflammatory effects. Portulaca oleracea (P. oleracea) were used traditionally for dietary, food additive, spice and various medicinal purposes. This review article is focus on the anti-asthmatic effects of P. oleracea and its constituents. Methods: Various databases, such as the PubMed, Scopus, and Google Scholar, were searched the keywords including "Portulaca oleracea", "Quercetin", "Anti-inflammatory", "Antioxidant", "Cytokines", "Smooth muscle ", and " Relaxant effects " until the end of Jul 2018. Results: P. oleracea extracts and its constituents increased $IFN-{\gamma}$, IL-2, $IFN{\gamma}/IL-4$ and IL- 10/IL-4 ratio, but decreased secretion of $TNF-{\alpha}$, IL-4 and chemokines in both in vitro and in vivo studies. P. oleracea extracts and quercetin also signifcantly decreased production of NO, stimulated ${\beta}$-adrenoceptor and/or blocking muscarinic receptors in tracheal smooth muscles. Conclusion: P. oleracea extracts and quercetin showed relatively potent anti-asthmatic effects due to decreased production of NO, inflammatory cytokines and chemokines, reduced oxidant while enhanced antioxidant markers, and also showed potent relaxant effects on tracheal smooth muscles via stimulatory on ${\beta}$-adrenoceptor or/and blocking muscarinic receptors.

  • Few studies of the side effects of the FMD vaccine have been performed domestically and studies in accordance to region have been limited. This study was performed by inoculating cows raised in the Daejeon province with the FMD vaccine and observing the side effects following inoculation. From January to February of 2011, 3,378 cows vaccinated with the FMD vaccine, in 143 different farms in the Daejeon province were analysed for adverse effects after inoculation. A total of 66 cows showed adverse effects after the first FMD vaccination and adverse effects observed were abortion/stillbirth (24, 36.4%), death (19, 28.8%), premature birth (14, 21.2%), skin lesions (8, 12.1%), vaginal swelling (1, 1.5%). A total of 29 cows showed adverse effects after the second FMD vaccination and adverse effects observed were abortion/stillbirth (17, 58.6%), premature birth (5, 17.2%), facial swelling (4, 13.8%), death (3, 10.3%). Through these results, continuous national research of the side effects of the FMD vaccine should be carried out continuously henceforth.

  • This paper introduces two R&D policy instruments of public R&D and business R&D subsidy into the growth model of endogenous innovation simultaneously, and studies how they respectively affect economic growth, as well as how they interact with each other for the growth effects. Main results are as follow. The growth effects of each instrument are non-monotonous but various depending on the structure of economy. For example, the growth effects of public R&D become positive in the economy of more innovation-friendly structure such as larger marker size, more monopolistic market structure and more patient consumer, but the growth effects of business R&D subsidy become positive in the economy of less innovation-friendly structure such as smaller market size, more competitive market structure and more inpatient consumer. Meanwhile business R&D subsidy does not affect the growth effects of public R&D, but public R&D affects the growth effects of business R&D subsidy. Particularly, in the economy of less innovation-friendly structure public R&D becomes complimentary to business R&D subsidy.
