  • This study was performed to investigated the flora and vegetation of Kokum-do island from July 1982 thru December 1983; and the findings hereof are summarized as follows: The flora investigated thereform comprises 737 species whih are classified into 128 families, 466 genera, 651 species, 79 varieties and 7 formae; and those which are worthy of close attention among the same include such endemic species of Korea as Celtis choseniana, Corylopsis coreana, Carpinus tschonoskii var. eximia and Tricyrtis dilatata, and a few plants, to be distributed in the north, such as Lilium distichum, Girardinia cuspidata and Orostachys sikokianus. Now that the said island belongs to the warm temperate zone, the distribution thereof consists of 120 species of evergreen plants including 74 species of evergreen broadleaf trees. The rich distribution of evergreen broadleaf trees in the island is thanks to the plantation thereof by the public organizations for scenic beauty. The destruction of flora in this island was caused by felling, fire nization and other human activities around 1940, and in particular, has been correlated with the population densiity of Yonhong-do, Sanghwa-do, and Hahwado islets; and that of top soil and ground vegetation in he quarry area of Ojon-ri town resulted from the collection of natural rocks an stones. It is evaluated as necessary that such evergreen broadleaf trees as Castanopsis cuspidata var. thunbergii, Machillus thunbergii and Ligustrum japonicum of Hyongje-do. Chun-do, Tok-do, Taech'wi-do, and Soch'wi-do islets, andPhyllostachys bambusoides, Caesalpinia japonica and Albizzia julibirssin of Kokum-do island, and Machillus thunbergii of Hongryon-ri town be under protection. The average DGN of the whole archipelago proves to be 5.84, which shows the tendency of the inverse proportion to the number of resident population per unit area. The pteridophyta distributed in this island comprises 39 species, and the coefficient of cryptogam as to the destruction of vegetation shows a high value of 1.4 which is regarded as indicating the diversified distribution of pteridophyta, forestbed shade plants under the forestbeds of some wellpreserved lots of this island. The naturalized plants, distributed in this island, were found out comprising a total of 23 species, and the Urbanization Index(UI) as to the destruction degree of natural vegetatioin shows a low value of 20.9.

  • The purpose of this study was to clarify the relationship between dental caries status, and the content of fluoride in drinking water, and the content of fluoride in enamel of deciduous teeth of Korean children. The specific areas selected in this study were Asan-Kun and Seouchon-Kun (Chung Cheoung Nam-Do) where the fluoride content in the deep well water were 0.9 ppm and 0.4 ppm respectively. The dental caries status of 720 children aged 6 to 11 who have been lived since birth was detected. The following results were obtained upon this study: 1. The def person rate, deft rate and def index of the Asan-Kun children were revealed 46.11%, 14.41% and 1. 69 respectively. The fluoride content in the outer layer of enamel was 430 ppm. 2. The def person rate, deft rate and def index of the Seouchon-Kun children were revealed 59.17%, 20.97% and 2.40 respectively. The fluoride content in the outer layer of enamel was 391 ppm. 3. The def person rate, deft rate and def index of the Asan-Kun children were showed lower value than the Seouchon-Kun children. The fluoride content of the outer layer of enamel of the Asna-Kun children were showed higher value than the Seouchon-Kun children.

  • This investigation was conducted to measure the effects of silkworm diseases on the cocoon crepe. The sample farmers were selected at three areas in Korea. a. Banga Ri, Namsa Myoen, Yongin Kun, Kyoenggi Do b. Moorim Ri, Yakmok Myeon, Chilkok Kun, Kyeongsangbuk Do c. Oero Ri, Buksam Myeon, Chilko Kun, Kyeongsangbuk Do 1. Reduction ratio of crops by the silkworm disease was 5.5% in spring season, and 8.9% in the autumn but 7.2% in a year. Including disease damaged cocoons being spoiled cocoons, it was 8.3%. 2. The ratio of disease-damage by the polyhedrosis virus and flacherie was 17.8% of whole disease at young instar and was 82.2% at advanced instar which showed highest ratio. 3. Average production amount of the cocoon was 27.74kg, The reduction amount by the silkworm disease against the estimated production aomunt was 2.411kg. 4. Reduction of amounts by unknown factors was 3.611 kg. This was 1.5 times of reduction amount by the disease. This nay be chiefly due to the missing silkworms and spoiled cocoons. 5. Ratio of farmers harvesting stable cocoon crops was 54.7% in spring rearing season but 21.9% in autumn. 6. Damage ratio of factors other than the silkworm disease was 10.70% and it was 17.87 % of total mortality.

  • 피쳐폰(Feature Phone)이 주를 이루던 초기 3G(Third Generation)는 사용자의 데이터 사용량이 많지 않았다. 그러나 스마트폰이 등장하면서 데이터를 이용한 서비스의 다양화, 저렴한 데이터 요금 정책으로 데이터 사용량이 대폭 증가하였다. 이동통신사가 예상하지 못한 데이터 사용량 증가로 3세대 망의 새로운 보안상 취약점이 나타났고 이를 이용한 DoS(Denial of Service) 공격이 발생하고 있다. 본 논문에서는 3세대 망에서 나타날 수 있는 DoS 공격의 하나인 DCH(Dedicated Channel) 고갈형 DoS 공격에 대한 논의하고 정상 사용자의 패킷 사용 패턴을 이용한 탐지 기법을 제안한다.
