  • The roots of Rosa rugosa have been used to treat diabetes mellitus in the folkloric society of Korea. To demonstrate the active component for the rat obesity induced by high fat diet for 6 weeks, the phytochemical fractionation and the pharmacological activity test were performed on this crude drug. It was shown that the methanolic extract and its EtOAc fraction inhibited the weight increase of the rat body, abdominal fat pad and hyperlipidemia at 200 mg/kg dose. Further, the triterpenoids, euscaphic acid and tormentic acid, isolated from R. rugosa roots were active at 30 mg/kg in the same assay. The two components shifted serum total-, HDL, and LDL-cholesterol levels toward the values of the unteated group, suggesting that the active compounds has hypolipidemic effects. The rats fad euscaphic acid and tormentic acid also reduced thiobarbituric acid-reactive substance (TBARS) and hydroxyl radical in the rat blood and increased superoxide dismutase activity compared to the control. TBARS values and carbonyl contest of the hepatic protein were reduced by treatment with the two triterpenoids. Antioxidative enzyme (SOD, glutathione peroxidase, and catalase) activities in hepatic were increased by treatment of rats with the triterpenoids, which suggests that triterpenoids inhibited the reduction of hepatic antioxidative activity caused by high fat diet. Taken together, these results support that euscaphic acid and tormentic acid improve a high fat diet-induced hyperlipidemia via the activation of antioxidative mechanism.

  • Objectives : This study aimed to overview the current education status of a traditional medicine by medical schools in Japan. Methods : We surveyed the literatures regarding a traditional medicine education in Japan, and get the information via email-interview with an officer of medical schools in Japan as well as from their websites. Results : Japan's education ministry presented the appropriateness of education for traditional medicine to medical students in 2001, and most of medical schools begun to set up the classes in Japan. We received the detail information of the traditional medicine education from 21 medical schools. Nineteen colleges(approximately 90%) of those have the regular classes for traditional medicine while two colleges don't have the education program for the traditional medicine. Most of medical schools have single class for introduction of traditional medicine, and have average $16.2{\pm}8.8$ hours during the $4^{th}$ grade(61.9%). Conclusions : We presented the general feature of education for traditional medicine in Japan, and this result would be basic information for an establishment of a strategy regarding the enhancement of national competitiveness of traditional Korean medicine.

  • To improve the physical properties of OCC (Old Corrugated Container) fibers, we used the mechanical pre-treatment on the fibers before refining . The mechanical action in the Hobart mixer induced high shear and compression on the fibers, which resulted in changes of fiber internal structure, and microcompressions on the surface of the fibers. We evaluated the amount of mechanical treatment on the fibers by fiber curl index for convenience. Four different refining techniques were applied to the pre-treated fibers (valley beater, Kady mill, PFI mill, and Impact refining) to find the best combination of the pre-treatment and the refining methods. Conclusions were summarized as followed. 1. Mechanical pre-treatment in Hobart mixer for more than 1 hour caused the increase of curl index of OCC fibers, and increased breaking length, burst index, and tear index the handsheets more than 10 % in this experiment. 2. Kady mill and PFI mill refining were effective in keeping fiber length from shortening Kady mill and Valley beater refining straightened out the fiber curls, and reduced the curl index. 3. Valley beating reduced fiber length very fast and generated fines more than other refining methods. 4. To increase breaking length and burst strength while keeping tear strength , combination of mechanical pre-treatment and Valley beating were most effective.

  • In our search for natural products affecting blood circulation, the n-butanol fraction from whole plant of Glehnia littoralis Fr. Schm. (GLB) improved blood lipid parameters, and ameliorated obesity in high-fat-diet (HFD)-fed C57BL/6 mouse model. Hyperlipidemia was induced by high-fat-diet for 4 weeks, and then GLB was orally administrated with 400 mg/kg/day for 4 weeks. GLB-treated group showed that the gain in body weight was significantly attenuated, the levels of total cholesterol and triglyceride significantly lowered on blood chemical analysis, and significantly prolonged the mice bleeding time when compared with those of HFD control group. Concomitantly, phytochemical composition of GLB was investigated by HPLC-hyphenated spectroscopy, and two major phenolic compounds, rutin and chlorogenic acid were identified in the GLB. Taken together, these results indicate that GLB has cardiovascular protective effects and could be a natural medicine candidate for the prevention of cardiovascular disease.

  • The changes in the wet pressing response of old corrugated container(OCC) stock depending on the beating treatment and the addition of polymer aids were investigated with laboratory roll press instrument. Two types of polymer aids, such as high molecular weight polymer with low charge density and low molecular weight polymer with high charge density, were applied in this study. The more beaten OCC stock showed the lower dryness after wet pressing. The addition of polymer aids had great influences on the wet pressing efficiency and paper properties. The dryness after wet pressing was increased by the addition of polymer aids, but the pattern of changes in dryness were different depending on the type of polymer and the properties of stock. The higher molecular weight polymer aids showed the greater increase in the dryness. The properties of paper such as air permeability, bulk, formation, tensile strength were also greatly affected by the addition of polymer aids.

  • Site elavation is one of the major factors which is influencing the incoming insolation. Because nonpermanent gases like ozone, water vapor are unmixed components of the atmosphere and their concentrations are function of height, the site elevation effects the relative proportion of the atmospheric constituents. We have measured solar radiation on Sobaek(1,350m) and in Poonggi area(280m). These values were compared to investigate the their charateristics and the potential for the solar utilization as an alternative energy for both high altitude area and low altitude area. From the results, we conclude that 1) Yearly mean 4,093 $kcal/m^2$. day of the horizontal global radiation in Mt. Sobaek was evaluated for clear day. 2) Insolation on Mt. Sobaek is $6{\sim}7%$ higher than Poonggi area during summer and winter seasons. 3) A significant difference of atomospheric clearness index is observed between Mt. Sobaek and Poonggi area at the same latitude.

  • K-Ar ages have been determined for the submarine basalts dredged from the P2 and P3 segments of the Phoenix Ridge, Drake Passage, Antarctica, for better understanding on the extinction of seafloor spreading. At the P3 segment, the K-Ar ages of the rifted ridge basalts are 3.5-6.4 Ma, and those for the axial seamount basalts are 1.5-3.1 Ma. The K-Ar ages for the basalts at the rifted ridge and axial central high in the P2 segment are 2.1 and 1.4-1.9 Ma, respectively. We suggest that the extinction of seafloor spreading at the P3 and P2 segments occurred at 3.3 and 2.0 Ma, respectively, on the basis of ridge structure and formation time of basalts. This result favors a stepwise extinction model rather than a simultaneous one on the extinction of the Phoenix Ridge.

  • Since 2006, the Law Commission and Scottish Law Commission have been engaged in a major review of insurance contract law, finally leading to the legislation of Insurance Act 2015. According to the enforcement of the Insurance Act 2015 on 12 August 2016, ss 18~20 of the Marine Insurance Act 1906(MIA 1906) were repealed and substituted by the new concept of fair presentation. This article intends to analyze the legal implications through the comparative research between the duty of fair presentation in Insurance Act 2015 and ss 18~20 of MIA 1906. The major changes in Insurance Act 2015 are designed to (1) encourage active engagement by the insurer rather than passive underwriting, asking questions of the insured if the desired information is not provided at the stage of proposal; (2) encourage policyholders to structure and signpost their presentation in an clear and accessible way, and prevent data dumps; (3) give guidance as to how the insured should prepare a fair presentation, by undertaking a reasonable search of available information and giving examples of what circumstances might be material; (4) clarify whose knowledge in the insured's organization is attributed to the insured for the purposes of disclosure; (5) clarify the exceptions to the duty of disclosure, including circumstances "which are known or presumed to be known to the insurer"; and (6) replace the remedy of avoidance in all circumstances with more proportionate remedies. This is a default regime, which may be altered by agreement between the parties.
