Water temperature during the culturing period was 10.4-25.5$^{\circ}C$ and there was a little difference between rearing sites. Salinity (25.00-31.17 psu) and DO (over 6.13 mg/l) showed reasonable condition for the growth of bay scallop. Concentrations of chlorophyll-a were ranged 1.69-7.40 $^{\mu}$g/l, and they fluctuated monthly in the every sampling site. During the growing period from June to October, dominant phytoplankton species were Ceratium sp. in Nammeon and Hoejin, Chaetoceros sp. in Dolsan. Density of phytoplankton was high in July, August and October, but it was low in September and November. When young bay scallops were cultured for 185 days in Nammyeon, Hoejin and Dolsan, shell heights were grown for 0.19 mm/day, 0.18 mm/day and 0.16 mm/day, respectively, and total weights were increased 0.16 g/day, 0.16 g/day and 0.13 g/day, respectively. Daily growth rates of shell height were 0.606%, 0.581% and 0.549%, and daily growth rates of total weight were 1.972%, 1.857% and 1.746%, respectively. Maximum predicted values of shell height calculated by von Bertalanffy growth model were 52.62 mm, 51.74 mm and 48.91 mm, respectively. Survival rate was the highest in Nammyeon (87.0%), but the rates in Hoejin and Dolsan sharply decreased after November.

The purpose of this study is planning a representative model of a modernized school with rearrangement of existing two primary schools(Nammyun and Namjin) and a middle school(Seonam) in Nammyun distric. Nammyun district, which is adjacent to Tae-an national ocean park, is the Place where gas a natural advantage. However, in the result of the rural exodus follwed by industrialization, the population in this province are decreased rapidly and it still be on the process of the rural exodus. Hence, the total number of students, each school is under 100 at the moment and the number will be less in the future. Under this consequences, the rearrangement of these school is inevitable. For the new modernized school plan Narnmyun district, estimate the scale of school on the basis of decreased number of students, the analysis the 7th education plan and the questionnaire and face-to-face interview investigation, which is a resident-orented investigation, were carried out preferentially. The major research contents are as follows; o Expansion of schools facility and space for operating the 7th education plan(classified level schools level and subject-based class school plan) o Over-all improvement of educational environment to take all-out advantages of school, social and home education. o The school which can take a part of an educational center of a rural community in schools off-time-after school and summer and winter vocation. o The school which is related to the local cultural, sports and entertainment utility, On the basis of this research, the basic concept and purpose of a new school model model plan in Nammyun will be established and the new school plan represented for the result of this research.

This study was performed to observe the present status of intestinal parasitic infections in a remote island, Yondo, located in southern part of Jeonranam-do (Province) , Korea. In February and May, 1988, total 1,011 individual stool samples were collected and examined for intestinal helminths and protozoa using formalin-ether centrifugal sedimentation technique. The results are summarized as follows: 1. Of 1,011 inhabitants examined, 398(39.4%) were positive for intestinal parasites. Helminth positives were 372(36.8%) , and protozoan cyst positives were 56(5.5%) . 2. Ten species of parasites were found. Trichuris trichiura revealed the highest infection rate of 27.5%, Ascaris lumbricoides 17.4%, Taenia sp. 5.8%, Entamoeba coli 3.3%, Ciardia Zamblia 1.5%, Endelimax nasa 0.8%, Hymenolepis nana 0.4%, Hookworm 0.2%, Trichostrongylus orientalis 0,2%, and Entamoeba histolytica 0.2%, respectively. 3. The female group showed higher positive rate(44.0%) than males (34.7%). Also, higher positive rates were observed among adults as compared with the group younger than 10 years old. 4. Average value of E.P.G. was 1,876(range 200∼17,800) in A. lumbricoides positives, and 327 (range 200∼1,600) in T. trichiura positive cases. 5. In helminth egg Positive cases, single in(traction was 63.4%, double infection 34.7%, and triple infection 1.9%, respectively. Among protozoan cyst positives, single infection was 94.6%, and double infection was 5.4%. The present study revealed that the prevalence of intestinal parasites among inhabitants in Yondo island is still so high that special control measures should be performed.
