이 연구는 중학생 사회과부도의 유선도의 색채 디자인을 사용자 중심으로 개선하는데 목적이 있다. 이를 위해 먼저 사회과부도 주제도의 색채 디자인에 대한 학생들의 선호도를 조사하였다. 그리고 지도의 색채 개선을 위해서 중학교 미술 교과서에 수록된 미술 작품에서 추출한 색채 팔레트를 이용하여 유선도를 제작하였다. 또한 지도 색채 이미지에 대한 감성 조사를 위하여 지도의 기본 속성과 색상에 대한 인식을 측정할 수 있는 20쌍의 단어를 사용한 의미차별법을 적용하여 설문 조사를 실시하였다. 결론적으로 학생들이 공통적으로 좋아하는 유선도는 흥미롭고 강렬한 인상을 주는 색상을 사용한 지도였다. 지도의 색상은 학생들의 지리 학습 흥미를 자극하므로, 사용자 중심의 지도 색채 디자인에 대한 연구는 지속적으로 이루어져야 한다.

To study the dining-out behaviour of housewives, the frequency, food preference, expense for dining-out in social meeting, family gathering, daily meal were surveyed with a total of 454 housewives in Pusan. (1) In the frequency of dining-out, once or twice a month shows highest percentage, 59.7% and 45.8% for social meeting and family gathering respectively. The occasion of dining-out for the daily meal is less than 1 or 2 time per 6 month (62.6%). The frequency of dining-out is highly dependent on demographic variables such as age, academic background, family income, car ownership. (2) The preference for Korean dishes is found to be top in all occasions for dining-out. And then for the social meeting, chinese food, western style food, japanese cuisine and fast food are prefered in order, while western style food and chinese cuisine are rather prefered than japanese cuisine and fast food in occasion for family gathering. When they dine out just for daily meal, korean food is prefered first and preference for chinese food, western style food, fast food is followed in order. Japanese cuisine is prefered the last. (3) Housewives answered highly that the expense they spend for dining-out for social meeting (45.8%) or family fathering (46.8%) is 5,000 to 10,000 won per person. For these occasions, the expense is different with family income. Namely, if their income is higher than 3,000,000 won, they usually spend 10,000 to 15,000 won for the occasion. And for the daily dining-out, 34.7% respondents answered that they spend 2,000 to 3,000 won.

Harvesting of marshfire glasswort (Salicornia europaea) by local people has been increased recently since this plant was known for a well-being food. Even though some harvesting sites are facing high risk of environmental pollution, Salicornia europaea is still harvested on a large scale. Therefore, to investigate safety of Salicornia europaea as a food resource, salt marsh environment, potential harvestable biomass, element and heavy metal accumulations in Salicornia europaea has been studied in three salt marshes, west-coast of Korea. Salicornia europaea showed 150 – 230g/㎡/yr harvestable biomass. Biomass and nitrogen contents of Salicornia europaea were closely related to soil nitrogen and carbon concentrations. Average Na, Zn, Fe, Cr accumulations in Salicornia europaea were 41479, 18, 297, 1.5 (mg/kg), indicating valuable trace element contents. However, average heavy metal accumulations such as As, Cd, Cu, Pb, Hg accumulations were 1.5, 7.1, 4.2, 1.5, 0.1 (mg/kg), which were even or higher than national standards (0.5, 0.5, 2, 2, 0.1) of salts. These results imply that harvesting and eating of Salicornia europaea in west-coast research sites would be harmful because the contents would be much higher if it is calculated as only considering salts and minerals. Therefore, harvesting of Salicornia europaea from some salt marsh in west-coast of Korea should be done cautiously.
