최근 일부 도심 지역에서 중산층이 특정지역으로 몰리며 원래의 거주자를 밀어내는 젠트리피케이션 현상과 주거비용 상승으로 인하여 도심에서 농촌으로 이동하는 유턴현상이 일어나고 있다. 이러한 이유로, 서울의 인구는 2016년 기준 28년 만에 천만 명이 붕괴되었다. 서울의 감소된 인구는 자연스럽게 수도권 외곽이나, 지방으로 분산되었고, 지자체의 인구가 초고령화로 나아가는 현재의 상황에서 지역사회에 도시민과 자본의 유입은 균형 있는 지방자치에 한 걸음 다가갈 수 있는 방법으로 활용 가능하다. 이와 같은 배경으로 풍부한 관광 자원과 지리적 이점 등을 이용하여 자본의 유입이 많을 것으로 예상되는 강화도 지역에 대해 강릉 카페거리 사례를 바탕으로 젠트리피케이션 모델을 검토 하고자 한다.

This study estimated the error involved in the areal average rainfall derived incomplete radar information due to radar partial coverage of a basin or sub-basin. This study considers the Han River Basin as an application example for the rainfall observation using the Ganghwa rain radar. Among the total of 24 mid-sized sub-basins of the Han River Basin evaluated in this study, only five sub-basins are fully covered by the radar and three are totally uncovered. Remaining 16 sub-basins are partially covered by the radar leading incomplete radar information available. When only partial radar information is available, the sampling error decreases proportional to the size of the radar coverage, which also varies depending on the number of clusters. It is general that smaller sampling error can be expected when the number of clusters increases if the total area coverage remains the same. This study estimated the sampling error of the areal average rainfall of partially-covered mid-sized sub-basins of the Han River Basin, and the results show that the sampling error could be at least several % to maximum tens % depending on the relative coverage area.

This study was to performed to assess social factors and physical health status. The subjects of the study were 103 elderly people of age over 85 years living in Ganghwa-gun area. The method of this research was based on the interview-survey with questionnaire. Chi-square test was the main data analysis method. The subject group was composed of 36 males and 67 females, the average age being 91.0 $\pm$ 3.2 years old for the males and 91.1 $\pm$ 3.4 years old for the females. The aged average height and weight were 161.0 $\pm$ 7.9 cm and 54.6 $\pm$ 7.8 kg in males, 141.0 $\pm$ 8.2 cm and 42.2 $\pm$ 7.9 kg in females which were lower than the Korean average standard but the mean BMIs of both male and female showed normal range. Their level of education was lower and they tended to be religious. The aged population might be economically poor. Their level of living standards tended to have been lower-middle and lower class. The mean age of their parents' death were 64.3 $\pm$ 17.2 years in males, 59.0 $\pm$ 14.9 years in females for the father and 70.9 $\pm$ 15.5 years in males, 66.8 $\pm$ 16.6 years in females for the mother. The rate of living together with their family or spouse in the female aged was $83.2\%$ higher than in the male aged. They tended to have engaged in hobbies that require less movement. Of the kinds of hobby, 'TV watching ($47.8\%$ in male and $44.9\%$ in female) was the highest. Ratios of the drinking and the smoking elderly were $30.6\%$, $25.0\%$ in male and $7.5\%$, $18.8\%$ in female but they tended to have never drunken and smoked. Of the subjects, $42.9\%$ spend 8$\~$9 hours for sleeping in male and $35.8\%$ spend 10 hours for sleeping in female. They tended to have not done any particular health behavior. The most common diseases were digestive disease in male, arthritis and hypertension in female. Most elderly males ($47.3\%$) and females ($61.2\%$) had 1$\~$2 diseases.

The mass transport is very complicated at the area which has the macro tide and complex geometry such as Gyeonggi bay. Especially, the long period current has a strong influence on the estuarine ecosystem and the long-term distribution of substances. The long period current is caused by several external forcing, whose unique characteristic varies spatially and temporally. The variation characteristics of long period current is analysed and its generation mechanism is studied. The tidal nonlinear constituents such as overtide and compound tide are generated due to nonlinear interaction and it causes mean sea level setup. The tidal wave propagating up into estuary is transformed rapidly by decrease of cross-sectional area and depth. Therefore the mean sea level is getting rise toward upriver. The high and low tide level is similar between down-river(Incheon) and up-river(Ganghwa) during neap tide when the tidal deformation is decreased. The tidal phase difference between two tidal stations causes a periodic fluctuation of sea level difference. The low water level of Ganghwa station during spring tide does not descend under EL(-)2.5 m, but the low water level of Incheon fall down under EL(-)4.0 m. The variation of tidal range and its sea level are increased during spring tide. It is found that the long period current $M_{sf}$ is quite similar to that of sea level difference between the two tidal stations. It means that the sea surface inclination caused by the spatial difference of tidal deformation is important forcing for the generation of long period current.

In order to distinguish the cultivation area of Panax ginseng, principal component analysis (PCA) using quantitative and qualitative data acquired from HPLC was carried out. A new HPLC method coupled with evaporative light scattering detection (HPLC-ELSD) was developed for the simultaneous quantification of ten major ginsenosides, namely $Rh_1$, $Rg_2$, $Rg_3$, $Rg_1$, Rf, Re, Rd, $Rb_2$, Rc, and $Rb_1$ in the root of P. ginseng C. A. Meyer. Simultaneous separations of these ten ginsenosides were achieved on a carbohydrate analytical column. The mobile phase consisted of acetonitrile-water-isopropanol, and acetonitrile-water-isopropanol using a gradient elution. Distinct differences in qualitative and quantitative characteristics for ginsenosides were found between the ginseng roots produced in two different Korean cultivation areas, Ganghwa and Punggi. The ginsenoside profiles obtained via HPLC analysis were subjected to PCA. PCA score plots using two principal components (PCs) showed good separation for the ginseng roots cultivated in Ganghwa and Punggi. PC1 influenced the separation, capturing 43.6% of the variance, while PC2 affected differentiation, explaining 18.0% of the variance. The highest contribution components were ginsenoside $Rg_3$ for PC1 and ginsenoside Rf for PC2. Particularly, the PCA score plot for the small ginseng roots of six-year old, each of which was light than 147 g fresh weight, showed more distinct discrimination. PC1 influenced the separation between different sample sets, capturing 51.8% of the variance, while PC2 affected differentiation, also explaining 28.0% of the variance. The highest contribution component was ginsenoside Rf for PC1 and ginsenoside $Rg_2$ for PC2. In conclusion, the HPLC-ELSD method using a carbohydrate column allowed for the simultaneous quantification of ten major ginsenosides, and PCA analysis of the ginsenoside peaks shown on the HPLC chromatogram would be a very acceptable strategy for discrimination of the cultivation area of ginseng roots.

Gangdo (江都), a reproduction of Gaegyeong, was the capital of Goryeo for 39 years. However, due to the urgent wartime situation of the Mongol invasion and the geographical features of Ganghwa Island, the castle system and palace layout were somewhat different from those of Gaegyeong. Gangdo's castle can be understood as a triple castle system consisting of outer castle, middle castle, and inner castle. First, the outer castle was the first to be completed, and it was built at the forefront to prevent the Mongol army from invading in the first place. It is presumed that the section was between Huamdon and Hwadodon in the outer castle during the Joseon Dynasty. The middle castle can be seen as the present 'Middle Castle', a castle built of earth on the outskirts of the Ganghwa-mountain Castle. Considering the sophistication and robustness of the construction method confirmed in the archaeological research, this castle is thought to have been built under a meticulous plan. In other words, as the capital city, it was completed 'at last' as recorded in the Koryo History, after a long 18-year construction process to protect palaces, government offices, and private houses. The inner castle was a castle with the character of a palace. This corresponds to the Old Castle of Ganghwabu (江華府) during the Joseon Dynasty, and it almost coincided with the scale of the composition of Gaegyeong's palace castle. It was a complex functional space, featuring the integration of the palace and the imperial castle, where the main government offices and ancillary facilities, including the palace, were located. Based on the documentary record that these palaces were similar to Gaegyeong's palace, the palace map was overlapped with that of Gaegyeong. The central axis of the building from Seungpyeongmun (昇平門) to Seongyeongjeon (宣慶殿) coincided with Kim Sangyongsunjeol Monument in Ganghwa- Goryeo Palace. Therefore, it seems that the palace of Gangdo had the same basic structure as that of Gaegyeong. However, the inner palace and annexed buildings must have been arranged in consideration of the topographical conditions of Ganghwa, and this is estimated to be the Gunggol area in Gwancheong-ri.

This study surveyed the Mt. Teomo·Hyeolgu and surrounding areas in Ganghwa Island, located in Ganghwa-gun, Incheon, to identify vascular flora and alien plants to be used as basic data for systematic management of the remarkable plants and biodiversity conservation. The survey was carried out 13 times from March 2019 to October 2020. The identified vascular flora of Mt.Teomo·Hyeolgu was 101 families, 321 genera, 517 species, 13 subspecies, 38 varieties, 5 forms, and 573 taxa. They accounted for about 12.35% of a total of 4,641 taxa of vascular plants in Korea. The identified Northern lineage plants, endemic plants, and rare plants on the Korean Peninsula as designated by IUCN were 68 taxa, 10 taxa, and 9 taxa, respectively. 69 taxa were classified as floristic target species. Three taxa, including Maui sedge [Carex thunbergii var. appendiculata (Trautv. & C.A.Mey.) Ohwi] were identified s Class IV and 14 taxa, including Violet Stanavoi clematis (Clematis fusca var. violacea Maxim.) were identified as Class III. The naturalized plants that appeared in the study site were 63 taxa, including daisy fleabane [Erigeron annuus(L.) Pers.], common ragweed [Ambrosia artemisiifoliaL.] and Canadian fleabane [Conyza canadensis(L.) Cronquist]. The above three species were found to have spread throughout Ganghwa Island and surrounding areas such as Seokmo Island, Gyodong Island, and Gimpo city. As introduced disturbing plants like prickly lettuce [Lactuca scariola L.], bur cucumber [Sicyos angulatus L.] and field dock [Rumex acetosella L.] have been newly reported in the Mt. Teomo·Hyeolgu area, mid- to long-term conservation measures should be established for native plants, such as remarkable plants, and also management measures like physical removal should be prepared at an early stage.

Tean Mado Shipwreck No. 3 is presumed to have been shipwrecked between 1260 and 1268. It departed from a Southern costal area of Yeosu in Jeonnam Province to Ganghwa Island, its final destination at which the temporal regime of Koryo Dynasty was located. In the shipwreck, a total of 35 wooden tablets were found, and forwarding places, senders, receivers, descriptions, and quantities of freight were written on the wooden tablets. The names of receivers included Kim Jun, who was influential in the late Musin Era of the Koryo Dynasty, and key institutions such as Junmin and Sambyulcho of the Musin force. Twenty wooden tables had lists of food items such as barley, abalone, salted-fermented abalone, mussel, dried mussel, salted fermented mussel, dried shark meat, fish oil, pheasant, and dried dog meat. The food items in the late 13th century were systematically examined using scientifically determined food organic remains and records of wooden tablets among the marine relics of Mado Shipwreck No. 3.

As a result of the sudden change of our society and the increasing employment of married women, it is necessary for men to participate in household works. The purpose of this study was to investigate consciousness of and participation in meal management of 30 to 50 years old Korean married men, living in Incheon and Ganghwa. The younger and the lower the education, consciousness about the meal management was lower. More than half of the subjects responded ‘Men can do participate in preparation of meals if necessary’ and the lowest of the subjects responded ‘Men should not participate in preparation of meals’. It showed that the consciousness of participation in meal management was changing positively. Although the consciousness of participation in meal management was positive, the real rate of meal management participation was not that high. Men were participated in grocery shopping, dish washing, cooking and menu planning in order. The average score of nutrition knowledge was high but there was no significant correlation between the nutrition knowledge and the participation in meal management. There were no correlations between the consciousness of and the participation in meal management. But there were strong correlations among each other in meal management behaviors such as grocery shopping, dish washing, cooking and menu planning. Our results suggested that nutritional education should be carried out in menu planning and cooking demanding knowledge and training.
