The weaving of Mosi(fine ramie) in the Hansan region was inscribed on the representative list of the UNESCO intangible cultural heritage in 2011. Unlike other fabric, as the Mosi is very sensitive towards humidity it needs different conditions for its workspace. The Hansan region is near the sea with many mountains around where it is easy for the Mosi to grow and is an appropriate place to weave Mosi. Recently the manpower for weaving of Mosi in the Hansan area is decreasing with the decrease of workspace drastically. After the investigation of workspace for the weaving of Mosi in the Hansan area, most of the places were done in individual houses and it could be classified in 1. Mosi storeroom, 2. Shed(Gwang che), 3. Dugout hut, 4. Under the toenmaru The depth of the dugout hut and under the toenmaru is around 80~60cm which is similar with the depth of the prehistoric dugout hut houses. The towns for weaving of Hansan Mosi are formed mostly in the Seochungun district, but the Hoamri Hansan-myeon and Gayangri Masan-myeon has the most traditional workspaces and they are still forming and maintaining the traditional town composition. However the numbers are too small and maintaining the traditional town is getting more difficult, so a plan for the maintenance should be made to continue to keep it as UNESCO intangible cultural heritage.

The purpose of this study was to identify food management behavior of housewives in island areas and to find if the behavior patterns were different between the regions, Hansan and Ullung island. An instalment based on previous researches was designed to measure food management behavior and was administered to 274 housewives in 1994 and 1998. Considering the condition of cooking-equipment possession, the percentage of possession for refrigerator, mix, electric range were significantly higher for households in Hansan Island than their counterparts. For food-budget planning, those in Ullung Island were more likly to plan their budget than those in Hansan Island. Menu planning patterns, considerable factors for food selection as well as cooking, and eating habits between meals were tuned out to be different between Hansan and Ullung areas. The findings of this study suggest that the condition of cooking-equipment possession, food-budget and menu planning, considerable factors for food selection and cooking, eating habits between meals were likely to vary depending on regions. Although housewives in two areas were living in island, they were not necessarily be uniform for all households but were diversified in food management behavior. Half of the respondents in Hansan Island and three-forth of the respondents in Ullung Island reported they had not planned their meal budget. The percentage of those who did not have their planned menu was 52.7∼54.1% in Hansan Island and 37.1∼38.5% in Ullung Island. When purchasing food material, housewives in Hansan Island consider the seasoning food as the most important factor, whereas those in Ullung Island consider family preference as the most important factor

In this study, the effect of sizing on the physical and mechanical characteristics of Hansan ramie was studied. 2 kinds of Hansan ramie were used for this study and one kind of the chinese ramie was also used for comparing with the characteristics of Hansan ramies. The following results were obtained from this experimental study. The wrinkle recovery angle was gradually reduced according to the increasing of the concentration of sizing agent. As the size agent could easily penetrate between the thick yarms, the effect of sizing on the wrinkle recovery angle was evident on the Chinese and Hansan coarse ramie. The result of KES-F system showed that the sizing affected much on the bending properties and shear properties. As the size concentration was increased the shear properties were increased more evidently on the Chinese and Hansan coarse ramie. The result of KES-F system showed that the sizing affected much on the bending properties and shear properties. As the size concentration was increased the shear properties were increased more evidently than the bending properties. The other mechanical properties didn't changed much by sizing. The calculated primary hand value also showed that the ramie became more stiff after sizing.

Ramie is one of the traditional fabrics in Korea, and very comfortable fabric for summer clothes because it has a high moisture-absorbing and transporting property. Futhermore ramie is very popular and Koreans prefer its handle for summer clothes. The kansan ramie has better quality as fibers and can be weaved as fine fabrics which are famous as kansan Fine ramie. Even though the good quality of kansan ramie has known widely, very few research work have been carried out on kansan ramie in the field of textile science. In this study, the analysis of the physical and chemical characteristics of Hansan ramie was conducted by using two different kinds of Hansan ramie: Hansan Fine ramie and kansan Coarse ramie. In addition, the same experiment was held on the one kind of chinese ramie to be compared with those of Hansan ramie. The following results were obtained from this experimental study. By the analysis of chemical composition of ramie, the similar chemical composition (a -cellulose: 83∼85%, pectin substances: 2.81∼ 3.01%) were found from all of the ramie fabrics used in this study. It has shown that Hansan coarse ramie has the highest toughness value and wrinkle recovery angle among the samples used in this study. From the result of KES-F system, it was found that Hansan Coarse ramie which is composed with the thicker yarns has the highest value on the bending properties, 2HG and surface properties. The primary hand value was also calculated by KN-203 LDY and value of Koshi was shown as the order of kansan coarse ramie> Chinese ramie> kansan fine ramie, and Hansan fine ramie had shown the highest Numeri and Fukurami value among the 3 samples used in this study.

To identify the kinds and the usage of Korean traditional foods, a survey was conducted for 112 housewives in Hansan-Do area by using a questionnaire. The data were collected from 1994 to 1998. The results showed that the development of traditional foods and their menu for fast foods was the highest, however the frequency to use the developed fast food was the lowest in their perception degree. Traditional foods were evaluated much better than the foreign foods.

The growth of the pearl oyster, Pinctada fucata was compared between two areas, Hansan Bay and Ilkwang located in southern part and in southeast part of Korean waters respectively, from November 1984 to June 1986. The pearl oysters in Hansan Bay grew from 2.53cm to 6.07 cm in shell length in 17 months, while those in Ilkwang grew from 2.53 cm to 4.07 cm in 19 momths. Shell height, shell breadth and total weight of the pearl oysters in Hansan Bay also showed more rapid growth than those in Ilkwang. The relative growth of shell breadth to shell length in specimens between Hansan Bay and Ilkwang showed a significant difference indicating that the value in Ilkwang is bigger than that in Hansan Bay, It is also suggested that Hansan Bay is a good area for the growth and Ilkwang, an area worth wintering of the pearl oyster.

This study was performed to investigate the physiological activity of Hongsan garlic and Hansan garlic, which were registered in the plant breeders' right in 2016. The content of mineral components, except sodium and sulfur ingredients, was found to be high in Hansan garlic. In addition, organic sulfur components were high in Hansan garlic. Moreover, the total soluble solid content, reducing sugar content, and alpha glucosidase inhibitory activity were high in Hansan garlic. Acidity, pH, total phenol, and flavonoid content were high in Hongsan garlic. Both varieties showed higher inhibitory activity to gram-positive bacteria than to gram-negative bacteria. The antimicrobial activity of Hongsan garlic was slightly higher than that of Hansan garlic. These results are expected to provide useful information to farmers who grow the above garlic varieties.

To study characteristics of the water quality in the Hansan-Geoje bay, we analyzed the long term monitoring data collected at the two sites during the period of 1987~2010. The trophic state of the waters in Hansan-Geoje bay was the mesotrophic level by the classification of Wasmud et al.[2001]. The water nutrients increased steadily from a wet season (Aug.), it reached the maximum concentration peak in a dry season (Nov.), and then decreased steadily to the winter, it reached at the minimum value in May in the next year. The result of factor analysis divided the waters of Hansan-Geoje bay into the five factors (nutrient, season, inflow land water, pollution, internal production) and the factors represented the 76.82% on the status of the waters. According to time series analysis, temperature, DO and bottom DIP were increased, and pH and COD were decreased during the period of 1987~2010. In particular, the fluctuation trend of DIN has been turned from oversupply to shortage by the N/P ratio since before and after 1990's. The water quality of the Hansan-Geoje bay has been recovered except DIP since 1987, despite of its geographical characteristic which is a general semi-closesd bay and a massive aqua-culture ground. To preserve the waters in Hansan-Geoje bay, we need to know on the cause of the increase or accumulation of DIP, and we should continue to study on the interrelation between the aqua-culture and water environment.

The vegetations of Hansan and Chubong islets in Tongyoungsi were investigated from April, 1997 to December, 1998 and a synthesis table was constructed. Based on the synthesis table, the vegetation was classfied into 6 communties: Pinus thunbergii community, Pinus densiflora community, Machilus thunbergii community, Chamaecyparis obtusa afforestation, Cryptomeria japonica afforestation, Miscanthus sinensis var. purpurascens community, and 3 subcommunities: Pinus thunbergii typical subcommunity, Quercus variabilis subcommunity, Carpinus coreana subcommunity. The vegetation of Pinus densiflora community around Jeseungdang area is well preserved. However the islet requirs the ecological restoration, and we suggest that the rare species such a Crypsinus hastatus, old trees of Machilus thunbergii and Pinus thunbergii, and the habitat for Machilus thunbergii and Camellia japonica must be preserved.

The purpose of this study investigates the effects of electron beam(EB) irradiation on the chemical and morphological properties of Hansan ramie fiber. Hansan ramie fibers were irradiated with electron beam doses of 0, 1, 3, 5 and 10kGy. The effect of electron beam irradiation on the chemical components of fibers as well as the surface chemical and morphological properties were investigated using chemical component analysis methods based on TAPPI standards, XPS, and SEM. The results indicate that the surface layers can be removed under suitable EB irradiation doses. Alcohol-benzene extraction and lignin content increases gradually with an increase in EB irradiation and reaching a maximum at an EB dose of 3kGy, and decreases at 10kGy. The surface chemical changes measured by XPS corresponded to the chemical composition analysis results. The C1 peak and the O/C ratio decreased with the removal of the multi-layer and primary layer by EB irradiation. The SEM images show the inter-fibrillar structure etched by EB irradiation up to 5kGy. At 10kGy, the surface structure of the ramie fiber shows highly aligned and distinctive striations in a longitudinal direction. The removal of these exterior layers of the fiber was confirmed by changes in surface morphology as observed in SEM images.
