최근 코로나 사태로 인하여 한국에서는 사람 간에 거리를 두는 사회적 거리 두기와 생활 속 거리두기를 시행하고 있다. 또 식당에서의 지출 중 가장 큰 비율을 차지하고 있다. 인건비를 절감하기 위해 본 연구는 2D Lidar 센서를 사용하여 식당에서의 사람과의 접촉이 가장 큰 서빙의 역할을 로봇이 직접 하는 것을 목표로 하였다. Lidar 센서를 이용해서 SLAM을 구현하였고 안드로이드 앱을 사용하여 주문 결제를, Four Bar Linkage를 사용하여 음식 전달 부분을 구현하였다.

In this study, the sand casting process was applied to design the gating system and perform casting simulation in order to domestically produce the submarine mast cover. Based on simulation results, casting experiments were conducted to produce a soundness prototype. The design concept of the mast cover's gating system was based on the design of bell casting. By arranging eight tower-type gates in a circle at 45° intervals, the flow of melt flowing into each gate was uniform and did not mix with each other, and the velocity of melt was also uniform. The mast cover made of Ni-Al-Bronze alloy has no unfilled parts. However, small porosities and flow marks occurred on the surface in several places. Yield strength and ultimate tensile strength are 279.3 MPa and 675.7 MPa, respectively, and elongation is 21.2%.

In this study, Sparassis crispa(cauliflower mushroom), which is rich in beta-glucan, was pulverized using ultrafine grinding technology for its potential utilization as a diverse food ingredient. The physical and antioxidant properties of cauliflower mushroom powder were evaluated at various grinding times. The results showed that as the grinding time of cauliflower mushroom increased, the average particle size significantly decreased (p<0.05). Additionally, the water-holding capacity, swelling capacity, and water solubility index of cauliflower mushroom increased significantly(p<0.05). Based on the analysis mentioned above, cauliflower mushroom prepared as a superfine powder for 5 minutes exhibited superior physical and chemical properties as well as antioxidant characteristics and is expected to be widely used in various foods.

Now the number value of total cholesterol is ascending as increasing consumption of meat in our country. In this point, total cholesterol examinee in urban and rural community, with age, with sex, classified and make percentage according to the abnormal. The current of abnormalities has been understood how changed during seven years. also present time, in good manner. The value used in analysis was drawn from 1984 to 1990 by Korean Association of Health Taegue branch and kyung-buk branch with the value of the abnormalities of total cholesterol in urban and rural community have been compared during past seven years. The result were as follows : 1) During past seven years. The total examinee were 107,945. Abnormalities of rural people in 74,693 were 1.4% and abnormalities of urban people in 34,252 were 2.7%. Now we find out that abnormalities of urban people are higher 1.3% than those of rural people. 2) In inspecting, 108,945 cases of total cholesterol abnormality with age are followed. Less than 20yr(0.3%) 20-29yr(1.0%) 30-39yr(1.5%) 40-49yr(1.6%) 50-59yr(2.4%) more than 60yr(2.5%). The percentage of abnormalities was increased with age in both sexes. 3) In male and female, the abnormality of male was higher 0.6% than that of female, respectively 37,525(2.0%) 71,420(1.7%) examinee of total cholesterol in 108.945.
