Chemicals related to hydrogen peroxide ($H_2O_2$) and nitric oxide (NO) generations were exogenously applied to Fusarium oxysporum f. sp. fragariae (Fof) causing Fusarium wilt disease in strawberry plants, and regulations of in vitro conidial germination and mycelial growth of the fungus by the chemical treatments were evaluated. $H_2O_2$ drastically reduced the conidial germination of Fof in a dose-dependent manner, and treatment with 3-amino-1,2,4-triazole (3-AT) catalase inhibitor also led to dose-dependent inhibition of conidial germination but relatively moderately. Gradual decreases in mycelial growth of Fof were found by high concentrations of $H_2O_2$, whilst exogenous 3-AT slightly increased the mycelial growth. Increasing sodium nitroprusside (SNP) NO donor, $N^G$-nitro-l-arginine methyl ester (L-NAME) NO synthase (NOS)-inhibitor and tungstate nitrate reductase (NR) inhibitor led to dose-dependent reductions in conidial germination of Fof in quite different levels. SNP conversely increased the mycelial growth but increasing L-NAME moderately decreased the mycelial growth. Tungstate strongly enhanced mycelial growth. Differentially regulated in vitro mycelial growths of Fof were demonstrated by SNP, L-NAME and tungstate with or without $H_2O_2$ supplement. Superoxide anion production was also regulated during the mycelial growth of Fof by nitric oxide. These results show that $H_2O_2$ and NO-associated enzymes can be suggested as fungal growth regulators of Fof as well as eco-friendly disease-managing agents in strawberry production fields.

The college's beauty department, which has a globalized education system that breaks away from the uniform beauty concept, can dominate in the fierce competition with other schools, and the development and vitalization of the department is guaranteed. In addition, research on the department name is very necessary to establish internal and external PR strategies for affiliated departments and departments and to analyze the direction of realistic beauty education. Accordingly, as a result of analyzing the trends of the department and department name by classifying the universities in Yeonghonam into four regions, the departments belonging to each region of the beauty department showed the most belonging to the natural science and arts and sports departments. In addition, the names of beauty departments by region are Busan and Gyeongnam, Daegu and Gyeongbuk, Gwangju and Jeonnam, and Jeonbuk with 5 beauty departments (29.41%), 3 beauty design schools (13.04%), and 8 beauty and beauty departments. (50.00%), beauty design departments, 2 schools (33.33%). This study makes it possible to cultivate professional beauticians who cultivate an artistic and creative sense that meets the educational goals of beauty education, and it is expected that it will be provided as a very necessary basic data for the division of departments or change of department name according to detailed majors.

Database integration has been recognized as a critical issue for effective logistics service in logistics environment. However, research related to effective methodology for this have been little studied, and also, prominent achievements have yet to be suggested. The aim of this paper is to present a quantitative methodology for the identification of conflict that is a representative problem on database integration. To achieve this aim, we suggested a quantitative methodology that can efficiently fine troubles such as name conflicts when schema integration, based on the level of semantic similarity between attributes and entities. And, in order to measure these semantic similarities, we used a thesaurus dictionary that proposed previous research. Finally, we presented effectiveness of the proposed methodology through some typical examples.

This article aims to investigate the geographical distribution and the cultural, historical, and symbolic meanings of the place names in the area of Bukhansanseong (Fortress), and to basically suggest the several features which have happened throughout the process of toponymic changes. In order to realize the purpose of the article, I collected the chronological toponymic data, particularly focusing on the Bukhanji (Record of Bukhansanseong, 1745) in which the most existing place names related to Bukhansanseong are recorded. In the meantime, I proposed the character of distributions and types of the physical, human place names according to the rear-part of toponymic morpheme, i.e. the generic name. Moreover, selecting the main place names such as 'Bukhansan', etc., I analyzed some features on the toponymic meanings and changes in accordance with the fore-part of toponymic morpheme, the specific name. Consequently, I identified the facts that the name of 'Bukhansan' in the era of the Three Kingdoms, 'Samgaksan' in the Goryeo Dynasty, and again 'Bukhansan' or 'Buksan' in the Joseon Dynasty era had been primarily called. And then the place name, 'Bukhansan' has been officially named until now since constructing the Bukhansanseong Fortress in 1711. Meanwhile, the physical place names related to mountainous and fluvial topography, the place names of artificial facilities such as a mountain fortress on this geographical environment, and especially Buddhistic place names which was named and identified by Buddhist monk, Seongneung who wrote the Bukhanji, representing the Buddhistic identity and ideology, form a large majority of the place names within Bukhansanseong.

This study aims to categorize and analyze internationally standardized sea names based on their origins. Especially noting the cases of sea names using country names and dual naming of seas, it draws some implications for complementing logics for restoring the name East Sea. Of the 110 names for 98 bodies of water listed in the book titled Limits of Oceans and Seas, the most prevalent cases are named after adjacent geographical features; followed by commemorative names after persons, directions, and characteristics of seas. These international practices of naming seas are contrary to Japan's argument for the principle of using the name of archipelago or peninsula. There are several cases of using a single name of country in naming a sea bordering more than two countries, with no serious disputes. This implies that a specific focus should be given to peculiar situation that the name East Sea contains, rather than the negative side of using single country name. In order to strengthen the logic for justifying dual naming, it is suggested, an appropriate reference should be made to the three newly adopted cases of dual names, in the respects of the history of the surrounding region and the names, people's perception, power structure of the relevant countries, and the process of the standardization of dual names. In order to endow East Sea with the meaning of the east of the Eurasian continent, westerners' perception on the Far East should be elaborated in more detail.

Background: It is controversial whether the change in nitric oxide (NO) expression in the dorsal root ganglia (DRG) may be responsible for developtment and/or maintenance of painful diabetic neuropathy. The aim of this study was to clarify the role of NO in the pathogenesis of painful diabetic neuropathy. Methods: The effect of L-nitroargine methylester (L-NAME) or sodium nitroprusside (SNP) on allodynia was measured in streptozotocin (STZ)-induced diabetic rats. NO concentration was measured in the cerebrospinal fluid (CSF) and plasma of the diabetic rats. NADPH-diaphorase (NADPH-d) histochemistry was performed on the DRG and spinal cords of the STZ-induced diabetic rats. Results: L-NAME, an inhibitor of nitric oxide synthase, alleviated allodynia, while SNP, a nitric oxide donor, aggravated allodynia in diabetic rats. Plasma NO level in the diabetic rats was significantly decreased compared with control rats. NO level in the CSF of diabetic rats did not differ from that of the control rats. NADPH-d positive cells were decreased in the DRG of diabetic rats. However, NADPH-d histochemistry in the diabetic spinal cord was not different from that of the control rats. Conclusions: Downregulation of NO expression in the diabetic rats may not be causally related to the development and/or maintenance of painful diabetic neuropathy.

Background: Partial nerve injury to a peripheral nerve may induce the development of neuropathic pain which is characterized by symptoms such as spontaneous burning pain, allodynia and hyperalgesia. Though underlying mechanism has not fully understood, sensitization of dorsal horn neurons may contribute to generate such symptoms. Nitric oxide acts as an inter- and intracellular messenger in the nervous system and is produced from L-arginine by nitric oxide synthase (NOS). Evidence is accumulating which indicate that nitric oxide may mediate nociceptive information transmission. Recently, it has been reported that NOS inhibitor suppresses neuropathic pain behavior in an neuropathic pain animal model. This study was conducted to determine whether nitric oxide could be involved in the sensitization of dorsal horn neurons in neuropathic animal model. Methods: Neuropathic animal model was made by tightly ligating the left L5 and L6 spinal nerves and we examined the effects of iontophoretically applied NOS inhibitor (L-NAME) on the dorsal horn neuron's responses to mechanical stimuli within the receptive fields. Results: In normal animals, NOS inhibitor (L-NAME) specifically suppressed the responses to the noxious mechanical stimuli. In neuropathic animals, the dorsal horn neuron's responses to mechanical stimuli were enhanced and NOS inhibitor suppressed the dorsal horn neuron's enhanced responses to non-noxious stimuli as well as those to noxious ones. Conclusions: These results suggest that nitric oxide may mediate nociceptive transmission in normal animal and also mediate sensitization of dorsal horn neurons in neuropathic pain state.
