  • One newly recorded species, Dryopteris namegatae, sect. Hirtipedes, was collected in forests in Jeju-do. Dryopteris namegatae (vernacular name: 'Tam-ra-top-ji-ne-go-sa-ri') was distinguished from other Korean congeners of sect. Hirtipedes of the genus Dryopteris by having stiff black scales on stipe and rachis, less narrowed base of lamina, and adaxial surface of pinna immersed along veins. Dryopteris hangchowensis ('Gak-si-top-ji-ne-go-sa-ri', new local name), recorded without any comments and description, was reexamined with similar taxa and was distinguished by smaller plants, brilliant leaves, many prominent fimbriate blackish scales on stipe and rachis, long-pointed apex of lamina and pinna, halfway-lobed pinna, and narrowest pinna. Descriptions and illustrations of the two species and their photographs in the habitat are provided along with a key to the species of sect. Hirtipedes of Dryopteris in Korea.

  • Ulmus davidiana var. japonica Rehder (Urticales: Ulmaceae) (UD) is a tree widespread in northeast Asia. It is traditionally used for anticancer and anti-inflammatory therapy. The present study investigated the effect of an ethanol extract of UD on vascular tension and its underlying mechanism in rats. The dried root bark of UD was ground and extracted with 80% ethanol. The prepared UD extract was used in further analysis. The effect of UD on the cell viability, vasoreactivity and hemodynamics were investigated using propidium iodide staining in cultured cells, isometric tension recording and blood pressure analysis, respectively. Low dose of UD ($10{\sim}100{\mu}g/ml)$ did not affect endothelial cell viability, but high dose of UD reduced cell viability. UD induced vasorelaxation in the range of $0.1{\sim}10{\mu}g/ml$ with an $ED_{50}$ value of $2{\mu}g/ml$. UD-induced vasorelaxation was completely abolished by removal of the endothelium or by pre-treatment with L-NAME, an inhibitor of nitric oxide synthase. UD inhibited calcium influx induced by phenylephrine and high $K^+$ and also completely abolished the effect of L-NAME. Intravenous injection of UD extracts (10~100 mg/kg) decreased arterial and ventricular pressure in a dose-dependent manner. Moreover, UD extracts reduced the ventricular contractility (+dP/dt) in anesthetized rats. However, UD-induced hypotensive actions were minimized in L-NAME-treated rats. Taken together, out results showed that UD induced vasorelaxation and has antihypertensive properties, which may be due the activation of nitric oxide synthase in endothelium.

  • There There is a difference in terms of administrative power in that the address of things are not an address under Public Act. In terms of location expression, it is possible to express the location more flexibly and in more detail than the road name address, so it should be improved so that it can be assigned and managed in an appropriate location, so that the location of the entire territory can be expressed together with the road name address. As a result of the comparison between the road name address and the address of things based on the analysis results of related laws such as the existing Road Name Address Act, the Building Act, and the Regulations on the Preparation and Management of Basic Address Information, it was confirmed that there are fundamental limitations of the address of things system. Accordingly, this study attempted to suggest ways to improve the address of thing system by broadly dividing it into the legal aspect and the addressable object aspect. From the legal point of view, firstly, it is necessary to improve the upper and lower level laws by unification together with a clear definition of the term subject of addressable object; secondly, according to the Building Act, facilities that are not used for residence among buildings must be given an address of thing; and thirdly, it is necessary to make it easy to use and link with heterogeneous public data by classifying the registration items of the basic address information map by type of geographical feature to be assigned an address. From the point of view of addressability, firstly, it must be given to all facilities in the relevant category so that it can be recognised that all specific facilities have object addresses, and secondly, it is necessary to be able to address the address of things to places that are used by many, even if there are no facilities.

  • Objective : The purpose of this study is to find out the possibility of application to herbal medicine's report form for adverse drug reaction (ADR) by reviewing and analyzing Asian countries's ADR report forms. Method : We investigated, compared, and analyzed ADR report forms (ADR-RF) of Asian countries's ADR institutions (ACAI), such as, Korea institute of drug safety & risk management and Dongguk university Ilsan oriental hospital (DUIOH) in Korea, national center for ADR monintoring (NCAM) in China, pharmaceuticals and medical devices agency (PMDA) in Japan, Ministry of Health and Welfare (MOHW) in Taiwan, and drug office, department of health, the government of the Hong Kong special administrative region (GHKSAR) in Hong Kong. Results : ADR-RF for ACAI included common contents, such as, patients information (name(initial), gender, age, weight), adverse event (AE)'s report information (Recognition and report for AE occurrence, first or follow up report, Severe AE), the detailed information of AE (the title of AE, onset & closing date of AE symptoms, the progress & results detailed test of AE), the information of AE's medicine (the types of medicine, product name, ingredient name, suspected or combination drug, single dose & frequency, dosage form, administration route, dealing for AE-suspected medicine), and AE reporter's information (reporter's information, institution's information). Taiwan had ADR-RF and the department exclusively for herbal medicine (HM), but others (except DUIOH) had not only no ADR report form but also contents for HM. Conclusion : ADR-RF for HM have to include the common contents of ACAI at least, as well as HM information related to ADR, such as the title, composition and types of HM, history related to HM's ADR, and the contents of drug-induced liver injury and so on. In addition, the main department of government for HM's ADR will be needed.

  • Objectives The purpose of this study was to investigate correlation between short stature and obese degree. And we also wanted to know the characteristics of patients visited clinic in the name of 'short stature'. Methods Height, body weight, BMI, fat mass, lean body mass, percent body fat were taken intended for 236 patients in the name of short stature. To all the patient questionnaire for growth clinic was drawn up, and ultrasound scan was taken through calcaneous of the right foot. The patients were classified to three groups - short, average, tall group - according to relative position of mid-parental height. It was analysed that the differences between groups in obese degree. Also was investigated correlation between position of short stature and obese degree, and between obese degree and bony maturity. Results & Conclusion 1. The average ages of patients in the name of 'short stature' were $12.69{\pm}3.93$ years old in boys, $10.66{\pm}3.67$ years old in girls. And it seemed to be just before second rapid maturing period. 2. The average BMI were $20.58{\pm}4.07kg/m^2$ in boys, $18.65{\pm}2.85kg/m^2$ in girls, and average percent body fat were $21.99{\pm}7.35%$ in boys, $26.01{\pm}6.35%$ in girls. 3. The numbers of obese children were 34(31.2%) in boys, 19(14.9%) in girls on the basis of BMI. And the numbers were 39(35.8%) in boys, 53(41.7%) in girls on the basis of percent body fat. There was a big difference in case of girls. 4. The numbers of AG(average group) were 48(44.0%) in boys, 60(47.2%) in girls, the numbers of SG(short group) were 35(32.1%) in boys, 31(24.4%) in girls, and numbers of TG(tall group) were 26(23.9%) in boys, 35(27.6%) in girls. 5. There were no significant differences among the groups in BMI, lean body mass, fat mass, percent body fat. Only significant difference in DI(disease index). 6. There were no significant correlation between PH(percent height) and BMI, leanbody mass, fat mass, percent body fat. Only significant correlation in DI(disease index). 7.

  • Over the past decades there has been a growing body of researches that examines the psychological traits related to safety outcomes. After briefly reviewing the relationships between psychological dispositions and safety outcomes, we empirically examine the relationships with 2 samples of 1,102 participants. Fifteen psychological dispositions (big 5 personality, locus of control, cognitive failure, affection from job and relations, 4 achievement goal orientations, self-efficacy, fatigue, and depression) and four psychological outcomes (safe behavior, unsafe behavior, accidents, and injuries) are examined. After covariance structure modeling variances of safety outcomes are well explained by simple 4 dispositions of consciousness, mastery-approach goal orientation, self-efficacy, and depression. We name them 'core safety disposition', and name four psychological outcomes 'safety consciousness', and the relationships between those latent variables are stronger than between measurement variables. We propose core safety disposition as a cause of safety consciousness, and discuss implications for research and practices.

  • Xiphasia setifer is reported for the first time from the South Sea of Korea based on a single specimen (291.0 mm SL) collected in September 2010. This species is characterized by the origin of the dorsal fin located vertically above the anterior margin of the eye; dorsal fin rays XIV, 114; anal fin soft rays 114, and vertebrae 130. The new Korean name of the genus Xiphasia is proposed as "Galchi-be-do-ra-chi-sok" and the Korean name of X. setifer as "Gal-chi-be-do-ra-chi", following Yamada et al. (2009).
