  • Storm surges caused by typhoon Billie, 28 Aug. ∼ 2 Sep. 1970, on the west and south coasts of Korea are studied with the tidal data. Tracks and frequencies of the typhoons which affected the Korean peninsula and the yearly maximum tidal deviation at tide stations for the past twelve years are also reviewed. It is assumed that most of the typhoons affecting the Korea peninsula cause variations of sea level along almost all of the coast of Korea. Maximum storm surges at each tide station on the south coast appeared to be caused by typhoons during the summer, and by the north westerly monsoon and extraordinary cyclones on the west coast during spring and winter. In the coastal waters of the west coast where depths are shallower and the bottom configuration is flat, sea level variation is mostly caused by atmospheric pressure and wind effect. When a typhoon travels as in case of typhoon Billie, sea level ascends generally on the south coast and it descends on the west coast before the typhoon approaches near to the coasts. Considering the large tidal range on the western and southern coasts, it is assumed that the extraordinary destructive surges can be occurred when the tide is high water. Reviewing the monthly mean sea level variations on the each coast, hazards to be caused by storm surges can more fluently occur during the summer.

  • Tarballs formed by HEBEI SPIRIT oil spill observed in the south-western sea of Korea from December 27 2007. The tarballs were removed by the response party, which Korea Coast Guard became a center of organization. The amounts of removing tarballs form the sea and the coast were 0.345 tons and 1,739 tons, respectively. The number of persons, in order to remove the tar balls from the south-western sea of Korea, counted about 97,000 persons, including 25,000 volunteers. In this paper, we introduced the response methods of tarballs entering into the south-western sea of Korea such as a landing net, meshes and so on.

  • The cluster analysis on the distribution of epiphytic lichens on the north, south, east and west slope of Mt. Hanra was carried out by three methods, sum of square algorithm (SSA), prinicipal component analysis (PCA) and multidimensional scaling method(MDS). Analysis of concentration (AOC) was used for the comparison between the lichen communities of north and south slope. The lichen species was identified 35 species by Hale and Culberson technique. The classification of sites by SSA method was divided into two areas in four slopes, and that of species by SSA, PCA and MDS methods was classified into three clusters in east slope, four clusters in south and west slope, and there clusters in north slope. The comparison between north and south slope of the distribution of lichens indicates that loight elevation of north slope (NH; 1600m~1900m) was similar to that of relative low elevation of south slope (SL; 1000m~1300m). The genus lichen, Anaptychia, Parmelia, Lobaria and peltigera was found as the dominant genus in both slopes.

  • Random Amplified Polymorphic DNA (RAPD) analysis was used to investigate the genetic variations of Coreoleuciscus splendidus within and among the West Korea Subdistrict populations (in Han and Geum Rivers) and the South Korea Subdistrict populations (in Seomjin and Nakdong Rivers). Twelve random primers were employed to generate RAPD markers. All primers were produced to identify specific RAPD markers between the West and South Korea Subdistrict populations. Analyses of genetic similarity and distance among the West and South Korea Subdistrict populations of C. splendidus also revealed similar results, with low genetic similarity (0.49~0.53) and high distance value (0.63~0.71). UPGMA dendrogram based on genetic distance was also similar in results. Therefore, the West Korea Subdistrict populations and the South Korea Subdistrict populations vary in genetic structure, and C. splendidus in the South Korea Subdistrict may represent a different species.

  • Daoism was introduced into the South-West of Vietnam via two main entries: the missionaries from North and Central Vietnam who migrated to the South by following the Southward movement and the spread of Daoism by Chinese migrant men who came and settled in the South-West of Vietnam from the late seventieth century to late nineteenth century. However, the biggest influence of Daoism in the Southwest of Vietnam was mainly the Chinese missionaries of Daoism. As time went by, together with the impacts of social and historical circumstances, Daoism had a strong influence on the lives of the South-West people in terms of different aspects, especially their faith and religions. The impact of Daoism into people's faith and religion was considerable, especially to the indigenous religions, of which the religion, Four Debts of Gratitude, is a representative example. With the aims of clarifying how Four Debts of Gratitude was influenced by Daoist thought and how the indigenous religions and systemized ideologies in the South-West of Vietnam were related during the period of living condition expansion as well as cohabitation of several ethnic groups in the region, this article focuses on Daoist thought expressed in typical symbols in the sacred architecture of the Four Debts of Gratitude such as Cổ Lầu, wine gourds, and the Eight Trigrams. Once properly examined, it becomes clear that the prominent symbols and other Daoist elements show that Daoism had a profound influence on the Four Debts of Gratitude.

  • We studied the maturity and spawning of Marbled sole Pleuronectes yokohamae from May 2006 to April 2007 in the Southern Sea of Korea. We analyzed monthly changes in maturity stages, gonadosomatic index (GSI), egg diameters, fecundity (F), total length (TL) at 50% group maturity, and sex ratio. The spawning period was November to February, and the main spawning period was December to January. The fecundity ranged from 75,155 eggs at 17.8 cm(TL) to 1,307,195 eggs at 36 cm (TL), and the relationship between TL and F was $F=3.656TL^{3.518}$ ($R^2$=0.872). The TL at first maturity was 17.8 cm and at 100% maturity, 32 cm. Thus, TL at 50% group maturity was estimated to be 19.8 cm. For sex ratio by length class, males were slightly predominant at sizes under 25 cm TL, but females were 100% at greater than 32 cm TL.

  • The purpose of this study was the analysis of electric energy consumption with the case study of tower type apartment's opening of building surface. We analyze the relationship between tower type apartment's opening of building surface and using electric energy consumption. The results of this study are: 1) The highest energy consumption of electric energy was on August without any influence of opening types of building surface. 2) Also, the south-west sides consumption of August was 848 kWh on Type B(one side opening) and it was the highest usage. 3) A house if facing west used more electricity than facing east when its opening of building surface's datum level is facing south. However, the house of facing east used more power than west when its opening of building surface's datum level is facing north. 4) When opening of building surface is facing on north-west or north-east, the opening of building surface's side of west and east used more electric power than north-west or north-east sides.

  • This study investigated the awareness and utilisation of library software by undergraduate students in universities in South-west Nigeria. The descriptive research design of the ex post facto was adopted using a sample of 1,527 selected from the total population of 239,048 undergraduate students in the universities. A questionnaire was used to collect the data. The finding of the study revealed that the extent of utilisation of library software by undergraduate students was high. Also, the majority of undergraduate students utilised library software in the university libraries between two to three times a week. Similarly, the findings show that awareness had an influence on the utilisation of library software by undergraduate students in the universities (r = 0.563, N = 1333, P < 0.05). The study concluded that awareness influenced the utilisation of library software by undergraduate students in universities. The study, therefore, recommends that the importance of the awareness of library software should be emphasized in the library to enhance its utilisation by the students in the university libraries.

  • A substantial part of South Africa is subject to more than one strong wind source. The effect of that on extreme winds is that higher quantiles are usually estimated with a mixed strong wind climate estimation method, compared to the traditional Gumbel approach based on a single population. The differences in the estimated quantiles between the two methods depend on the values of the Gumbel distribution parameters for the different strong wind mechanisms involved. Cluster analysis of the distribution parameters provides a characterization of the effect of the relative differences in their values, and therefore the dominance of the different strong wind mechanisms. For gusts, cold fronts tend to dominate over the coastal and high-lying areas, while other mechanisms, especially thunderstorms, are dominant over the lower-lying areas in the interior. For the hourly mean wind speeds cold fronts are dominant in the south-west, south and east of the country. On the West Coast the ridging of the Atlantic Ocean high-pressure system dominate in the south, while the presence of a deep trough or coastal low pressure system is the main strong wind mechanism in the north. In the central interior cold fronts tend to share their influence almost equally with other synoptic-scale mechanisms.
