Biocomposite was fabricated with biodegradable polymer and natural fiber that has potential to be used as replacement for glass fiber reinforced polymer composite with the benefits of low cost, low density, acceptable specific strength, biodegradability, etc. Until now, mostly natural cellulosic fibers on land have been used as reinforcement for biocomposite. The present study focused on investigating the fabrication and the characterization of biocomposite reinforced with red algae fibers from the sea. The bleached red algae fiber (BRAF) showed very similar crystallinity to the wood cellulose. It has high stability against thermal degradation (maximum thermal decomposition temperature of 359.3$^{\circ}C$) and thermal expansion. Biocomposites reinforced with BRAF have been fabricated by a compression molding method and their mechanical and thermal properties have been studied. The storage modulus and the thermomechanical stability of PBS (polybuthylenesuccinate) matrix are markedly improved by reinforcing with the BRAF. These results indicate that red algae fiber can be used as an excellent reinforcement of biocomposites, which are sometimes called as "green-composites" or "eco-composites".

The bleached red algae fiber(BRAF) showed very similar crystallinity to the cellulose, furthermore, it has higher thermal decomposition temperature than that of the microcrystalline cellulose(MCC). Polypropylene biocomposites reinforced with BRAF have been fabricated with various BRAF contents by compression molding method and their mechanical and thermomechanical properties have been studied. The mechanical strength as tensile, impact and flexural modulus of BRAF/PP biocomposites were gradually improved with increasing the BRAF content, and thermal property which against the thermal expansion was markdly improved, especially. These results are compared with chopped non-woody fibers as Henequen or Kenaf, BRAF was more effective for fabrication of biocomposites reinforced small-sized fibers. The red algae fiber reinforced biocomposites has the applicability such as electronics, biodegradable products and small-structure composites.

Purpose : This study was attempted to check the correlation between job satisfaction and turnover intention and to provide the basic information to increase job satisfaction of fire fighters. Methods : A total of 369 questionnaires were distributed and 354 questionnaires were filled out and collected for analysis. Results : There was difference in turnover intention by general characteristics. According to position, group of Fire lieutenant or more is lower than that of Fire sergeant or less (F=3.61, p=.014). The group of rescue & emergency service and administration was significantly lower than other groups(F=4.84, p=.001). In pattern of duties, day service group was significantly lower than shift work group in .05 level(t=2.59, p=.022). Finally, in the correlation, the more job satisfaction increase, the more turnover intention decrease that represents inverse correlation between job satisfaction and turnover intention(r=-.523, p <.001). Namely, it represents the results that the higher job satisfaction is low turnover intention. Conclusion : More studies of fire officer in other cities are required to generalize the results. We have to develop program for job satisfaction for fire officer firstly, because program for job satisfaction used in this study was not developed for fire fighters.

Objective: We report on the administration progression and adverse event of Er-Xian decoction for menopausal hot flushes. A hot flush is a rapid and intense heat-dissipation reaction that involves considerable sweating, enlargement of the peripheral blood vessels, and internal body heat. Er-Xian decoction is a prescription for treating menopausal hot flush symptoms in postmenopausal women. We report administration progression and adverse event of Er-Xian decoction for menopausal hot flush. Methods: We used the Menopause Rating Scale and Menopause-Specific Quality of Life questionnaire to evaluate the progression of hot flushes, and we conducted a literature review to determine the effective dosage of Er-Xian decoction. Result: In all cases, Facial hot flushes and evaluation variables were improved by the administration of EXD. However, in Case 1, a rise of liver function indexes which may be related to EXD administration was observed. Conclusion: Considering that menopausal flushing usually lasts for several years, The resluts are meaningful that the short-term administration of EXD led to improvement of symptoms. In order to further use EXD in the future, it will be necessary to conduct follow-up studies on the subject of safety verification, such as repeated dose toxicity studies.

Agar, a heterogeneous polymer of galactose, is the main component of the cell wall of marine red algae. It is well established as a safe, non-digestible carbohydrate in oriental countries. Neoagarooligosaccharides (NAOs) prepared by hydrolyzing agar by microbial β-agarase have been reported to show safety. However, their immunological effects have not been reported yet. Thus, the objective of this study was to investigate immune enhancing effects of neoagarooligosaccharides (NAOs) from marine red algae Gelidium elegans in mice by performing ex vivo experiments. Six-week-old mice were fed ad libitum. NAOs were orally administrated at three different concentrations (100, 500, and 2,500 mg/kg B.W./day) twice a week for four weeks. The group fed with NAOs at 2,500 mg/kg showed the highest proliferation of splenocytes and production levels of cytokines (IL-1β, IL-6, TNF-α) in the ex vivo experiment. In conclusion, NAOs can enhance immune function, increase proliferation of splenocytes, and increase cytokine production by activating macrophages in mice.

Red-algae agar, consisting of D-galactose and 3, 6-anhydro-L-galactose, is usable for bio-ethanol production if hydrolyzed to monomer unit. The objective of this study is to produce bio-ethanol from agar using the heat and acid-treatment. Bio-ethanol was produced by Saccharomyces cerevisiae KCCM1129 strains using agar-pretreatment. The optimal condition for reducing sugar conversion by agar was found to be 15 min reaction at a HCl concentration of 0.1 N and $120^{\circ}C$. The optimum concentration for maximum cell growth was 0.1 N NaCl (17.88 g/L). Over 0.1 N NaCl, the cell growth decreased to 6.78~10.76 g/L. At 16% agar concentration, the ethanol production obtained by optimum pretreatment was found to be 10.16 g/L.

Objectives: The purpose of this study is to find diagnostic points and define the cut off values of hot flashes by using digital infrared thermographic imaging. Methods: Thermographic images of 75 patients with hot flashes (HF, n=35) and non-hot flashes (NHF, n=40) were retrospectively reviewed. We used the temperature difference between Ex-HN3 and CV17, LU4, CV12, CV4 for diagnosing hot flashes. The temperature differences of between two groups were analysed using independent samples t-tests. The cut off values were calculated by received operating characteristic curve analysis. Analyses were undertaken using SPSS version 17.0. and p-value of <0.05 was considered significant. Results: The temperature difference Ex-HN3 and LU4 were the most significantly different between groups (p<0.001). Using receiver operating characteristic curve analysis, the sensitivity, specificity, and area under the curve were 65.7%, 72.5%, 0.729, respectively. The optimum cut off value was defined as $1.00^{\circ}C$. Conclusions: These results suggest that the digital infrared thermographic imaging is a reliable instrument for estimating hot flashes.
