This study aims to investigate and analyze the plan and structural system of 4 kan(間) by 4 kan(間) square church built in early 20th century. At that time, three kinds of traditional wooden structure church had been built under the circumstances of transitional era : Basilica style such as Ganghwa Anglican Church, 'ㄱ' shaped style such as Keumsan Church and $4{\times}4$ Square style such as Bukok Church and Jacheon Church that are concerned in this study. Traditional plans and structural system were mixed with new religious function and transformed into korean peculiar style. $4{\times}4$ Square style is a residual product in that process. Despite of it, little concerns on it till now. The results of this study are described as follows. 1. The plan of these $4{\times}4$ square churches is divided into three areas : cathedra($1{\times}1$), attendance($4{\times}2$), and intermediation($4{\times}2$). The location of cathedra is commonly the opposition part of main gate and projected out of the building. Attendance area was also divided into two, man and woman, because of keeping a distance with each other. 2. The structural system of these $4{\times}4$ square churches are somewhat different because of their size and roof style. In the case of Bukok church, $4{\times}4$ square fall off $3{\times}3$ and $2{\times}2$ gradually and turn into paljak(八作) roof, which enable us to get in traditional entering methods. On the contrary, Jacheon church use hipped roof but almost alike pyramidal roof, which could make us not to recognize entering in the aspect of gable part.

In this study, we compared demographic anthropometric characteristic, health-related lifestyle and diet behavior among weight control behaviors of 1187 (555 male, 632 female) aged $40{\sim}69yrs$ in Ganghwa country. All the data were analyzed by chi-square test, trend test, student t-test using SPSS 12.0 version at p < 0.05. 'Attempting weight control (loss)' was more in women than that was found in men (36.6% vs 20.7%), and women attempting weight loss most were 40-50 yrs. The reasons of weight loss were 'health problem' and 'health promotion'. Physical activity and diet restriction were commonly employed as weight control methods. Both genders attempting weight loss had a higher education level, BMI, percentage of body fat, waist circumference and physical activity than those not attempting weight control (p < 0.05). In dietary habits like 'meal regularity', 'slow eating' and 'over eating', women attempting weight loss were superior than those who not attempting weight control group (p < 0.05). Eating pattern changes like 'decrease of fats and fatty foods intake', 'vegetable oil usage', 'increase of fruit and vegetables intake', 'decrease of sugar and salt intake' showed significant differences (p < 0.001) between the attempted weight control groups and nonattempted weight control groups. Salt taste was a preference in male non-attempted weight control group, while sour, hot and spicy taste were preference in female attempted weight control group (p < 0.05). Preference for processed foods, fried foods and snack were significant differences (p < 0.05) in women attempted weight control group. Those attempting weight loss tried to improve their eating patterns. However, those attempting weight loss were poorer than the others in health-related lifestyle and eating habit. Therefore, it is necessary to make an effort that improve healthrelated lifestyle and diet behavior in middle aged group.

For successful microalgal biodiesel production, the strain should be selected carefully. Fast growth rate and high fatty acid contents are desired traits for algal biodiesel production. In ocean cultivation of microalgae, seawater temperature slowly changes over seasons, and rotating algal strains in accordance with their optimal temperature could improve overall productivity. Additionally, use of indigenous strain is preferred to alleviate potential impacts on the environment. In this study, five strains of Tetraselmis sp. from nearshore of Youngheung Island, Incheon, Korea, were isolated during winter and characterized for their growth patterns and fatty acid compositions in the low temperatures ($5-15^{\circ}C$). The five strains showed various characteristics in optimal growth temperature, fatty acid contents, and compositions. Compared with a strain of Tetraselmis sp., isolated from Ganghwa island in a previous study, a rapid-growing strain with 237% higher biomass productivity and an oleaginous strain with twice higher fatty acid contents at $10^{\circ}C$ were isolated. The oleaginous Tetraselmis strain showed the highest fatty acid productivity among the strains, having 438% higher productivity than the previous strain. Using the new isolates in the seasons with low seawater temperature would improve microalgal fatty acid productivity in ocean cultivation.

The advantage of biofloc technology (BFT) in aquaculture is in the prevention of pathogenic transmission. In this study, we performed an investigation on viral, bacterial, and microsporidian parasite infections targeting a total of 194 whiteleg shrimp Litopenaeus vannamei reared in seven BFT-farms on the west coast of Korea in 2021. Hepatopancreatic and cuticular epithelium and pereiopods tissues of shrimp were tested for the four pathogens, Enterocytozoon hepatopenaei (EHP), Vibrio parahaemolyticus causing Acute Hepatopancreatic necrosis disease (VP_AHPND), white spot syndrome virus (WSSV), and hepatopancreatic parvovirus (HPV). The microsporidian parasite EHP was detected in the hepatopancreatic tissue of BFT whiteleg shrimp in the Ganghwa region, whereas no other pathogenic bacteria or virus was detected on the shrimp in the seven BFT-farms. As a result of bacterial flora in the rearing water of BFT whiteleg shrimp using DNA microbiome technology, V. chemaguriensis and V. alfacsensis were contained at 0.05% and 0.01%, respectively, but no VP_AHPND was detected. These findings will serve as a basis for supporting safe BFT-aquaculture of whiteleg shrimp.

The Ministry of Agriculture and Forestry announced promoting the project, 'Regional Agricultural Clusters,' in Feb. 2004 through 「The Comprehensive Plan for the Agriculture and Agricultural Communities」 and initiated a model project from 2005. The purpose of 'Regional Agricultural Clusters' is to develop regional agriculture by concentrating the resources and capacities of the region and maximizing the effect of integrating related projects. 31 towns in Geonggi and 2 towns (Ganghwa and Ongjin) in Incheon were chosen for the study based on the crop areas of 36 agricultural products from the Agricultural Census in 2000. For those 33 towns, factors such as the top 20 agricultural products, main producing districts and surveys on each towns were considered and we have concluded that these items are good subjects for 'Regional Agricultural Clusters' : We have decided on 18 items for what we call, 'Mini-Clusters,' a cluster in which the item's main producing district is in only one area of the town in question (in 30 projects out of 21 towns). Secondly, we have decided on 11 items for what we call, 'Base-Clusters,' a cluster in which the item's main producing district can be associated by name with the item, the production is sizeable, and can be found in several locations of the town in question (in 13 projects out of 11 towns). Finally, we have decided on 12 items for what we call, 'Broad-Based-Clusters, a cluster which the item's main producing district expands the past the vicinity of the town in question (in 19 projects out of 19 towns).

Analysis and prediction of storm surges are very important because the global warming has raised sea levels and increased the frequency of massive typhoons, accelerating damage of coastal flooding. However, the data for storm surge prediction is lacking due to the short history of observation in South Korea. The purpose of this study is to investigate the spatial and temporal characteristics of the previous surges and tsunamis based on the historical documents published during the Joseon Dynasty. In addition, we tried to evaluate the damage and spatial extent of such disasters, using the expressions about surge records including heights and number of administrative divisions. As a result, a total of 175 records of surges and tsunamis were compiled from 1392 to 1910: 145 events were extracted through the analysis of the ancient documents, and 30 events were from the previous research. Most of the strorm surges occurred along the west coast during summer season. More than half of the total surges were concentrated for 120 years from the mid 1600s to the mid 1700s, which was estimated to be highly relevant to the climate conditions in East Asia during the Little Ice Age. Hazardous areas by storm and tidal surges were also extracted, including Asan, Ganghwa, and Siheung during the Joseon Dyanisity period.
