  • Phytochemical examination of Barks of Ulmus macrocarpa has led to the isolation and characterization of two fla-vanonol, taxifolin $7-O-{\beta}-D-glucopyranoside$ (1), taxifolin $3'-0-7-{\beta}-glucopyranoside$ (2), two flavanone eriodictyol $7-O-{\beta}-D-glucopyranoside$ (3), nalingenin $7-O-{\beta}-D-glucopyranoside$ (4), three flavan 3-ol, (+)-catechin (5), (-)-epicatechin (6), (+)-catechin 7-O-{\beta}-D-glucopyranoside (7) and one proanthocyanidin, procyanidin B-1 (8). Antioxidative activity of these compounds was determined by measuring the radical scavenging effect on 1,1-diphenyl-2- picrylhydrazyl (DPPH) radicals . (+)-Catechin (5) , (-)-epicatechin (6), (+)-catechin $7-O-{\beta}-D-glucopyranoside$ (7) and procyanidin B-1 (8) showed significant antioxidative activity.

  • Kyoaesamultang(KAT) has been used as an important prescription for various diseases including threatened abortion, associated with pregnancy in traditional medicine. In oder to identify the safety of KAT, this study was designed to determine mutagenicity and hepato-toxicity. In Rec-assay, Bacillus subtills H-17($Rec{^+}$) and M-45($Rec{^-}$) strains were used to clarify the DNA damage property. In Ames test, Salmonella typhimurium TA98 and TA100 were used for mutagenicity testing. In SOS umu test, Salmonella typhimurium TA1535 containing plasmid pSK1002 was used as a tester strain, and the levels of umu operon expression were monitored by measuring the $\beta$-galactosidase activity. From tested results, KAT did not show DNA damage and mutagenicity. On the other hand, hepato-toxicity of KAT to female ICR mice was monitored by the measurements of s-GOT, s-GPT and LDH activities after oral feeding for 15days. KAT showed 34% increase of s-GOT and s-GPT activities, also exhibited 35% increase of LDH activity in mice sera.

  • Purpose: This study was conducted to develop nursing outcome indicators based on nursing activities done for stroke patients. Method: focus group meeting and delphi technique, which consisted of clinical nurse experts, neurologist, and nursing professors. CVI(Index of Content Validity) and user validity test was performed. Result: 12 nursing diagnoses, 29 nursing interventions and nursing outcomes were identified. The former were from NIC and the latter were developed according to nursing interventions. They were verified by experts in focus group. 199 nursing activities were identified, 133 nursing outcome indicators were developed. In user validity, usefulness and usability were tested. Conclusion: This systemic approach of measuring nursing outcomes verified nurses' positive effects in changing patients health status and nursing contributions in the health care system as a profession.

  • This study will contribute to improve intimacy and interests of students in mathematics and to cultivate their abilities and attitudes to continuously learn through problem posing activities using fairy tales. An experimental study was carried out two classes of the fifth grade (total 60 of students, each group 30 os students) in G elementary school located in Daegu Metropolitan City. This experiment was performed for thirteen weeks. For this study, using two examination devices for measuring mathematical attitude and learning achievement, pre- and post-tests were carried out. As a result, it was found that two groups are identical groups. Problem posing activities with fairy tales had significant effect on mathematical attitudes of children and learning achievement of children.

  • To investigate activities in the evacuated situation of people, the measurement system is newly constructed, that composed of a wearable sensor device of heart beats rates and mobile devices like an Android smartphone with a bluetooth low energy (BLE) connection. Smartphone not only displays the heart beats variation (HBR) and the current location of evacuation person by Global Positioning System (GPS), but also exports the CSV formatted file that would be used for further analyzing the activity of person in detail. As an example of the application of this system, we show the case of evacuation routes for elderly person in Hizen-Hamashuku Area, Saga Prefecture. Using the proposed measuring system, the activities of evacuates can be clearly shown on the map of Geospatial Information System (GIS).

  • Sachungwhan reduced hepatotoxicity induced by carbon tetrachloride($CCl_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), blood urea nitrogen(BUN), creatinine(CRE), total cholesterol(TCHO), triglyceride(TG), low density lipoprotein cholesterol(LDL-CHO), high density lipoprotein cholesterol(HDL-CHO), total protein(TP), albumin(ALB) and total bilirubin(BIL) in serum. Hepatic parameters monitored were levels of cholesterol(CHO), triglyceride(TG), malondialdehyde(MDA), content of cytochrome P450(CYP), level of glutathione(GSH), and activities of NADPH-CYP reductase, superoxide dismutase(SOD), catalase(CAT), glutathione S-transferase(GST), glutathione reductase(GR), glutathione peroxidase(GPx). The histopathological examination showed that the treatment of Sachungwhan relieved the ballooning degeneration of hepatocytes which had been generated by $CCl_4$. The results suggested that hepatoprotective effects of Sachungwhan possibly are due to their promising antioxidative activity.

  • P. ginseng C.A. Meyer is one of the most widely used herbal medicine in Asia. It has been used for the treatment of many disorders. Its major constituent is known to be ginsenosides, and there are many documents about bioactivities of ginsenosides such as anti-oxidant, anti-tumorigenic, anti-fatigue, and anti-inflammatory activities. Some of these activities are supposed to have some correlation with inhibitory action of cyclooxygenase (COX). Ginsenosides from P. ginseng and sapogenins were evaluated for their inhibitory effects against both cyclooxygenase-1 and -2 (COX-1 and -2). Inhibitory activity was evaluated by measuring prostaglandin E$_2$ (PGE$_2$) production from arachidonic acid with an ELISA reader. (omitted)

  • Difficulties in the measuring home food production activities obstructs development of home production activity related studies. For solving such problems, this study intended to develope a home food production frequency scale. The data were collected from 219 housewives in Taejon. Validity, reliability, correlation, and multiple regression analysis were used to test home food production frequency scale. The scale's validity and reliability were reveled considerable potential for its use to ascertain relationships between home food production activity and other family variables.

  • Phytochemical examination of Barks of Ulmus macrocarpa isolated two flavanone, three flavanonol, three flavan 3-ol and one procyanidin compounds. We also determinated the antioxidative activity of these compounds by measuring the radical scavenging effect on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals. Three flavan 3-ol (catechin, epicatechin and catechin-7-O-$\beta$-O-xylopyranoside) and procyanidin B1 showed significant antioxidative activity. (omitted)

  • The U.S. Congress has been known to effectively control the bureaucracy. On one hand, Congress adjusts the degree of discretion provided to the bureaucracy when making agencies or legislation: ex ante control. On the other hand, it also performs the oversight activities to punish or correct undesirable behaviors of bureaucrats: ex post control. While the dynamics of each control mechanism is widely examined theoretically, few have attempted to empirically investigate this with a special attention to partisan politics in Congress. I attempt to fill this gap by measuring the two types of control mechanisms, testing theoretical assertions, and analyzing the dynamics under the two control mechanisms.
