  • The fungal genus Alternaria is comprised of many saprophytic and endophytic species, but is most well known as containing many notoriously destructive plant pathogens. There are over 4,000 Alternaria/host associations recorded in the USDA Fungal Host Index ranking the genus 10th among nearly 2,000 fungal genera based on the total number of host records. While few Alternaria species appear to have a sexual stage to their life cycles, the majority lack sexuality altogether. Many pathogenic species of Alternaria are prolific toxin producers, which facilitates their necrotrophic lifestyle. Necrotrophs must kill host cells prior to colonization, and thus these toxins are secreted to facilitate host cell death often by triggering genetically programmed apoptotic pathways or by directly causing cell damage resulting in necrosis. While many species of Alternaria produce toxins with rather broad host ranges, a closely-related group of agronomically important Alternaria species produce selective toxins with a very narrow range often to the cultivar level. Genes that code for and direct the biosynthesis of these host-specific toxins for the Alternaria alternata sensu lato lineages are often contained on small, mostly conditionally dispensable, chromosomes. Besides the role of toxins in Alternaria pathogenesis, relatively few genes and/or gene products have been identified that contribute to or are required for pathogenicity. Recently, the completion of the A. brassicicola genome sequencing project has facilitated the examination of a substantial subset of genes for their role in pathogenicity. In this review, we will highlight the role of toxins in Alternaria pathogenesis and the use of A. brassicicola as a model representative for basic virulence studies for the genus as a whole. The current status of these research efforts will be discussed.

  • Corrosion damage of boiler, factory equipment and so forth occur quickly due to using of the polluted water, resulting in increasing leak accident. Especially, working life of hot water boiler using the polluted water becomes more short, and energy loss increases. The cathodic protection method is the most economical and reliable one to prevent corrosion damage of steel structures. Mg-base alloys galvanic anode protection of cathodic protection methode is suitable for the application of hot water boiler using water with high specific resistance such as tap water. This paper is studied on the cathodic protection characteristics of hot water boiler. In tap water solution, the measurement of cathodic protection potential according to the time elapsed is carried out, and behavior of cathodic polarization with current change is investigated. The main results obtained are as follows. In hot water boiler shell, the open circuit potential of base metal become less noble than that of weld Bone, and the current density of base metal becomes low than that of weld zone. The further distance from Mg-alloy galvanic anode, the higher cathodic protection potential of hot water boiler appears. And protective potential becomes high according to pass cathodic protection time and after 6∼10 days become stable.

  • Baik-Eui is the white clothes and Korean typical way of wearing, Baik-Eui was used by the over 80$\~$90 percents of people, which proves that Baik-Eui was the very clothes of common people. Moreover, even King himself in Koryo Dynasty is said to have worn white clothes when he was out of official hours. And wearing Baik-Eui was regarded as polite manners among the noble men in Yi Dynasty in spite of strict prohibitions of wearing it. That fact proves that it was loved by Korean people in general. Baik-Eui can be found its origin from many peoples of North East Asia in ancient time. Some say that wearing Baik-Eui is considered as a kind of worship of the sun, or purity of Korean people. But from the economical point of view, Baik-Eui was primitive in it's color. It means that their clothes were made from original clothes, not dyed. This study on the social reasons affecting to Baik-Eui, they are summarized as follows; 1. This Baik-Eui had been originated from the ancient economical and rigid circumstances of society. Everlasting poverty and diprivation of joy in life of Korean naturally made them have inclination of wearing it 2. Also common people were restricted in their choice of dress color by government. Even rich could not wear a colored clothes except the dyes permitted by them. 3. Socially, People wore white clothes through various kinds of ceremony, among which funeral was the most important. As we had the large family system, and usually the funeral at that time was longer in its period than now. Thus, Korean got accustomed to wear whit clothes more and more.

  • This article is on the introduction and origin of Korean Neo-Confucianism. In this article, it is verified and clarified that a scholar named Jeong, Sin-bo (鄭臣保) from Southern Song settled on today's Seosan Ganwoldo (看月島) in the year of 1237 (24th year of the king Gojong in Korean Dynasty) and he introduced the Neo-Confucianism both by Jeong, Myung-do (程明道) and Jeong, Yi-cheon (程伊川) who are also called Double Jeong to Korean scholars. Based on these facts, it overturns the history that Anhyang (安珦) first introduced Neo-Confucianism to Korean Dynasty in the year of 1290 even with 35 years ahead. When this gains official approval by the academia, the history of Neo-Confucianism seems to be rewritten. This article first examines changes in history of Korean Neo-Confucianism with three stages and then concentrates on the life of Jeong, Sin-bo. It presents that Jeong, Sin-bo was a descendant of a Southern Song's noble family named Pogang Jeong (浦江鄭氏) and he committed to Chunqiu thoughts (春秋思想) and spirit of loyalty (義理精神) naturally as the posterity of Pogang Jeong. Lastly, it also infers the transmission of Jeong, Sin-bo's scholastic mantle and his influence on the posterity.
