  • Beech mushroom (Hypsizygus marmoreus) is one of the most popular mushrooms in Japan, China, and Korea because of its delicious taste, nutritious value, and unique crunchy texture. In 2018-2019, unusual signs on the mushroom were observed in mushroom farms in Gyeongnam Province. The main signs were the inhibition of mycelial growth and primordial formation on the surface of mushroom media. When green mold caused contamination at early stage, the rate of pinhead formation by the mushroom greatly decreased to 46.5-71.5%. Conidia of the causal green mold were ellipsoidal, dark green, and measured 2.0-3.1㎛ long. The optimum temperature for mycelial growth of the green mold was 25℃. The phylogenetic tree obtained from the internal transcribed spacer (ITS) rDNA sequences showed that the isolated green mold corresponded to Penicillium brevicompactum (100.0%). This is the first report of green mold contamination caused by P. brevicompactum on H. marmoreus.

  • Data of the typhoon affecting Korean peninsula from 1951 to 2005 are obtained from the RSMC best track and six climatological characteristics of the typhoons are examined. Local wind speeds are obtained by the physical model for wind fields. Typhoons are generated by the Monte Carlo simulation and their wind speeds are distributed using Weibull CDF. Simulated typhoon wind speeds are used to obtain different wind speeds corresponding their mean recurrence intervals.

  • This study reports the history of abacus calculation in the East and West and the changes in the curriculum of abacus calculation in Korea. The findings from this study are that abacus calculation education program already disappeared from public education and that it depends on private education institutes or after school classrooms. According to a case study, of the 110 elementary schools located in Changwon City and Gyeongsangnam-do Province, 74 schools were educating abacus as after-school programs.

  • Stem rot of Stachys sieboldii occurred sporadically in the farmer's fields at Shindeung-myeon, Sancheonggun, Gyeongnam province in Korea. The infected leaves and stems are water-soaked, rotted, wilted and finally leads to the death of the whole plants. The sclerotia, 1-3 mm, white to brown, globoid, were formed on lesions and the surface of soil line. The optimum temperature for mycelial growth and sclerotia formation was $30^{\circ}C$ on potato dextrose agar. The typical clamp connections were observed in the hyphae of the fungus. On the basis of mycological characteristics and pathogenicity to host plants, this fungus was identified as Sclerotium rolfsii Saccardo. This is the first report of stem rot on S. sieboldii caused by S. rolfsii in Korea.

  • Stem rot symptoms of Convallaria keiskei occurred sporadically in the herb exhibition field at Hamyang-gun Gyeongnam province in Korea. The typical symptom is water-soaking on the main stem, rotting, wilting, and blighting, which eventually leads to death of the plant. The sclerotia, which were white to brown in color, globoid in shape with size of 1~3 mm hyphal width of which was 4~9 ${\mu}m$, were formed over lesions and surface soil line. The optimum temperature for mycelial growth and sclerotia formation was $30^{\circ}C$ on PDA. The typical clamp connections were observed in the hyphae of the fungus grown on PDA. Mycological characteristics and pathogenicity to host plants indicated that the infected fungus was Sclerotium rolfsii Saccardo. This is the first report of stem rot on Convallaria keiskei caused by S. rolfsii in Korea.

  • The results of the survey conducted mainly in the Gyeongsangnam-do province are as follows : First, 31.6% (65 schools) of the total elementary schools in the eight Cities Dong Districts of Kyungsangnam-Do Province are larger than the appropriate schools. 51.9% (107 schools) are the most suitable schools. The number of small schools with less than 300 students was 35 (17.0%). Of the 138 elementary schools in City Up-Myun districts, 11.6% (16 schools) account for big schools larger than the appropriate size. The number of schools with adequate size is 18.1% (25 schools), while 97 schools with 70.3% of small schools occupy the majority. Of these, 10.1% (14 schools) account for less than 150 small schools. Second, three large schools (2.2%) are larger than the appropriate schools among the 137 elementary schools in the nine districts of Gyeongsangnam - do, and 17 schools (12.4%) are suitable for small schools. Less than 300 small schools 117 schools (85.4%), of which 111 small schools (81.0%) accounted for the majority. Third, as a result of the analysis by the subdivision into the provinces, municipalities, and counties, small - scale schools accounted for the majority of municipalities and counties. Therefore, considering the local environment, it is necessary to establish appropriate school proper size policy differentiated from municipal school.

  • The purpose of this study were to describe the problems of rural women in changing rural society and environment in Korea, to search for the development directions, and propose strategies for improving rural women's welfare. Related literatures and existing data were reviewed to investigate the present conditions, social-economic status, and economic activities of rural women in Jinju city, Gyeongsangnam-Do province. Jinju city had relatively higher percentage of farming people and rural women than other cities's of Gyeongsangnam-Do, and agriculture occupied important portion in industrial sector in the area. According to the Jinju 21C Vision Project, the city was planning to build eco-friendly environment and welfare rural society. To achieve the goals and objectives of the project, the following points should be considered: 1) Success of the project may depend on how to motivate and support rural women to participate actively in the project. 2) Jinju city should set up some practical strategies for improving the status of rural women who take key roles in environment and agriculture. 3) The city should establish strong support system and practical programs for rural women in building eco-friendly Jinju city.

  • The egg Positive rate of Enterobius vermicularis and Clonorchis sinensis of school children in the rural area was studied in Hamyang-gun, Gyeongsangnam-do in Korea. Cellotape anal swab and formalin ether concentration methods were performed one time to 720 Primary school children. The total egg Positive rate of E. vermicularis was 12.6% in two schools (Baekjeon and Wiseong). In the Baekjeon and Wiseong primary school, the egg Positive rate of E. vermicularis was 4.6% and 13.4%, respectively Pinworm egg Positive rate was 17.6% in the lower grades (1st, 2nd and 3rd), and 7.7% in higher grades (4th, 5th and 6th). The total egg Positive rate of male and female was 12.6% and 12.7%, respectively. The egg Positive rate of C. sinensis of Baekjeon and Wiseong Primary school was 1.5% and 0.46%, respectively The total e99 Positive rate of C. sinesis was 0.56%. This survey showed that continuous education and chemotherapy is necessary to treat and prevent reinfection of E. vermicularis. In the case of C. sinensis, health education for school children is recommended to prevent potential infection of adolescents.

  • We investigated the occurrence of red tide, harmful algal blooms(HABs), at the end of 14th century until the beginning of 19th century recorded in the Annals of the Joseon Dynasty, which are the authentic and encyclopedic annual records of the Joseon Dynasty of Korea. In total, 81 cases of HABs are recorded in the annals for which authors draw a table and maps. The number of HABs occurrence at each sea is as follows: 68 times at the South Sea; 50 times at the East Sea; and 23 times at the Yellow Sea. A region hit by red tide most frequently was Gyeongsang-do Province (over 80 times), which borders on both the South Sea and the East Sea. HABs written in the annals follow two distinctive occurrence patterns. The first pattern shows red tide started at Gangwon-do Province in March, spread north to Hamgyeongnam-do Province in April, and moved further north to Hamgyeongbuk-do Province in May and June. On the other hand, the second pattern shows red tide occurred in Gyeongsangnam-do Province in August and then expanded north to Gyeongsangbuk-do Province in September. HABs generally happened from March to September, culminating in August. Paralytic shellfish poisoning incidents involving human deaths were reported in Jinhae, Geoje and Tongyeong, occurring February to June. Fish mortality increased throughout Gyeongsang-do Province from July to September. HABs occurred on an extensive scale from 1394 to 1451 and again from 1654 to 1706. HABs also occurred on a lesser scale from 1493 to 1534 and again from 1588 to 1609. In general, vast HABs occurred in odd years (1399, 1403, 1413 and 1681).
