  • Steel structures of the seaside area are naturally led to surface corrosion due to incoming salt. Signature measures for this are to replace steel with steel material with a high corrosion-resistance and to block salt and other deteriorative factors beforehand through finishing work such as surface coating. However, the variety in steel materials, finishing type, and construction methods makes adhesive weight of incoming salt different depending on each type. For this research, measurement results derived from an enhancement experiment on artificial incoming salt adhesive to 4 steel finishing types and 2 material types identified a difference of adhesive weight by each sampler.

  • During the 1995 Hyogoken-Nambu earthquake, many caisson-type quay walls in Kobe Port moved several meters towards the seaside due to liquefaction and subsequent ground flow, To investigate the mechanism of quay wall damage, we carried out the numerical simulation using the 2-D effective stress analysis. Input earthquake motions used for the analyses are original Dip wave and the component wave in each compact support of wavelet transformation. The results suggested that the shear failure occurred in the foundation soil underneath the caisson type quay wall due to the deformation of the caisson type quay wall.

  • This study estimated rainfall information more effectively by image signals through the information system of weather radar. Based on this, we suggest the way to estimate quantitative precipitation utilizing overlapped observation area of radars. We used the overlapped observation range of ground hyetometer observation network and radar observation network which are dense in our country. We chose the southern coast where precipitation entered from seaside is quite frequent and used Sungsan radar installed in Jeju island and Gudoksan radar installed in the southern coast area. We used the rainy season data generated in 2010 as the precipitation data. As a result, we found a reflectivity bias between two radar located in different area and developed the new quantitative precipitation estimation method using the bias. Estimated radar rainfall from this method showed the apt radar rainfall estimate than the other results from conventional method at overall rainfall field.

  • The genus Acymatopus Takagi is reported for the first time from Korean fauna along with two nominate species, A. minor Takagi, 1965 and A. takeishii Masunaga, Saigusa & Yang, 2005. This genus belonging to the subfamily Hydrophorinae in the family Dolichopodidae. It comprised of only six species in the world and distributed only in Japan and China thus far. The genus is diagnosed by a metallic bluish-green body with thick gray tomentum, lacking black and white markings of mesonotum, 2 pairs of long marginal setae at scutellum and male's dorsally slightly curved fore tarsomere 1. Both adults and larvae of this genus are known to be found on rugged and rocky marine shores of the tidal zone. The authors found the first recorded species in the west seaside of Korea, where many barnacles inhabit. The descriptions and illustrations of external features including male genitalia of newly recorded species are provided in this paper.

  • The purpose of this study is to investigate the relation between social education and secondary education of seaside and sea village schools for supporting the successors to fishery. Objects of the study were five groups; 321 fishermen, 107 staff members of a Fishery Guidance Center, 1, 001 students, 306 teachers of sea villages, 193 staff members of a Fishery Cooperative Association. The total number of people being object of this study was 1, 876 persons. The questionaire used for this study was made after preliminary counseling with fishermen in sea villages and teachers in seaside schools. The results of this study are as follow ; 1) About the value of Fishery and successors to Fishery There have been more positive responses than negative ones to the question on the value of fishery. The main reason for positive responses lies in the potentiality for development of fishery but the negative responses are because of the heavy work. 56.8% of the respondents expected an increasing number of successor to fishery, but 43.2% of the respondents had a negative foresight on that problem. The negative respondents stated that the fisherman that moved from the sea villages to the urban areas are responsible for the none increasing numbers of successors to fishery. Most of the respondents answered that government support is needed in order to increase the number of successors to fishery. 2) Social education for Fishermen Only 40% of fishermen know the Fishing Village Guidance Center as the main institute for social education. 94.17% of the respondents prefer plural institutes to single ones. 5.9% of the respondents answered with opposit opinions. 40.4% of the respondents answered that technical teachings has not often been practised. The reason why technical teaching does not often come into effect are as follows; lack of technical expertise, insufficient concern of staff members of the Guidance Center or the Cooperation Association. Also fishermen answered that the Fisherman Guidance Center does not often practise technical education. The Fishery Cooperation Association with its social education for fisherman takes the role of education for the economical way and carries out financial assistance. The relationship between the Fishery Cooperative Association and fishermen is presented satisfactory. However, the frequency of education is not satisfactory. Indifferences between staff members of the Fishery Cooperative Association does not carry out fishery education very often. Also loaned money matters were not satisfactory. 3) Secondary education for Fishery This study showed that it is desirable that the practical course of middle schools in islets and seaside villages take education on fishery ; however, a few schools only take the practical course fishery. Most of the fishery high schools want computer education as a new recommendable course. The students of fishery high schools want computer education as a new recommendable course. The students of fishery high schools have problems with scientific terms in the text books for the practical of fishery high schools have problems with scientific terms in the text books for the practical courses. Over 80% of the respondents agreed that the principals of schools in islets and sea side villages should be men having majored in fishery. 4) The connection between social education and secondary education for fishery a. It is desirable that the principal and vice principal of secondary schools in islets and sea side villages are men majored in fishery. b. It is recommendable that fishery courses are taken as practical courses in fishery village schools for it is helpful to relate between the vocation and the district's special character, as well as to built up relation between the middle school education and the fishery high school education. c. The teachers of fishery high schools and the officials of government offices which are related to fishery should work together to realize a program on teaching various kinds of techniques and give other useful informations to fishermen. d. During the vacations the fishery high school could be used for the social education of fishermen. Seminars on fishery technique and cultural aspects could be held. Especially a spiritual education which is needed for the improvement of the society of fishermen could be achieved by a cultural education. e. On the state level a financial support to raise the number of successors to fishery, a national policy for the betterment of the life of fishermen, as well as active publicity activities are necessary. f. A financial support of the government for raising the number of the successors to fishery is needed. For this purpose a fishery education performed on a state level would be desirable.

  • To provide data for the improvement of primary health care through the study on the utilization rate of community health practitioner(CHP) post and its related factors toward some rural residents in Mooan County Chollanamdo, a questionnaire survey was made from 382 persons during August 1999. Comparison was made between persons at the seaside area under difficult transportation and persons at the railroad area under convenient transportation. The results are as follows: 1. For the last one year, 83.3% of seaside area residents and 67.0% of railroad area residents used CHP post. As the purpose of visit to CHP post at seaside area, 94.3% visited for medical care, 25.3% for chronic disease control and 22.2% for health counselling and 14.1% for chronic disease control. 2. By simple analysis, sex, age, marital status, educational level, residence area, distance from living village to CHP post, presence of chronic diseases, satisfaction with CHP and confidence on CHP were related significantly with the utilization of CHP post for the last one year. 3. By multiple logistic regression, statistically significant variables related with the utilization rate of CHP post for the last one year were analyzed as age, sex, residence area and distance from living village to CHP post.

  • Korean entomopathogenic nematode strain were evaluated against white grubs, Popillia quadriguttata, Ectinohoplia rufipes and Phyllopertha diversa in laboratory. In addition we examined the efficacy of entomopatogenic nematode, Heterorhabditis sp. KCTC 0991BP strain against white grubs in Seaside Golf Club in Gimpo, Gyeonggii and persistence of entomopatogenic nematode in fairway of Anyang Benest Golf Club in Gunpo, Gyeonggii. In laboratory Heterorhabditis bacteriophora Hamyang strain showed 95% mortality against Popillia quadriguttata. H. bacteriophora Hamyang strain and Heterorhabditis sp. KCTC 0991BP induced 80% mortality against 3rd instar of Ectinohoplia rufipes. However, the letter showed only 60% mortality against Phyllopertha diversa. White grub density was reduced to 39% by the application of Heterorhabditis sp. KCTC 0991BP at the rate of $2.24{\times}10^9$ infective juveniles $ha^{-1}$ compared with control in Seaside Golf Club. Heterorhabditis sp. KCTC 0991BP persisted for two months at $5{\sim}10$ cm soil depth but not persisted at $0{\sim}5$ cm soil depth for the same periods when applied at the rate of $2.47{\times}10^9$ infective juveniles $ha^{-1}$.
