연간 원유생산량 약 200만톤, 1998년 6월 1일부터 인하하였다고 치면 200만톤의 12분의 7인 117만톤, $5.4\% 인하시 톤당 가격은 29,036원이며 1998년에만도 약 340억원, 1999년도 약 580억원의 혜택을 본 셈이고, 이중에서 약 20억원을 각출하자는 것이었는데 무임승차자가 있었다는 것은 한번 깊이 반성해 보아야할 대목이 아닌가 싶다.

미국의 항공우주산업은 전세계 시장에서 1989년에 약 16조원의 무역수지를 기록하였는데, 이는 1988년의 약 13조원보다 24%나 증가한 것이다. 이러한 반면에 미국 항공우주분야의 수입은 1989년에 약 7조2천억원으로 결정을 이루었는데, 이는 1988년의 약6조6천억원에서 겨우 10% 증가한 것이다. 군수용 항공우중 상품의 경우 1989년 수입은 1988년에 비해 거의 2배로 증가하였다

약은 약답게 먹어야 약이다. 잘못 먹으면 위해가 될 수도 있고, 독약이 될 수도 있고, 때로는 맹물이 될 수도 있다. 특히 기생충 약은 남용의 경향이 있다. 검변도 없이 신문광고를 보고 맘대로 선택, 투약 하는 것- 여기에는 아무런 문제가 없을가

The objective of this study was to determine the quality characteristics of fried yakgwa and baked yakgwa prepared with different amounts of P. frutescens powder. Moisture contents of fried yakgwa were 7.05%, and moisture content of baked yakgwa with different amounts of P. frutescens powder were 12.42~10.44% and decreased with higher amount of P. frutescens powder. This result can be attributed to loss of water in yakgwa in the course of the fried process. Although the degree of expansion of baked yakgwa was lower than that of fried yakgwa, size and shape of yakgwa were maintained. Yakgwa is appropriate as a cookie type product. Crude lipid contents of fried yakgwa were higher than those of baked yakgwa due to the exchange reaction of water and fat during the fried process. Energy of fried yakgwa was 501 kcal and was higher than that of baked yakgwa with different amounts of P. frutescens powder. This greatly affected the fat content of each sample. Energy of baked yakgwa increased with higher amount of P. frutescens powder due to the characteristics of the ingredients or jasoyeop. For chromaticity determination, L values of fried yakgwa were lower, but a, and b values were higher than those of baked yakgwa, and L, a, and b values decreased when P. frutescens powder increased. Texture measurement showed that hardness, cohesiveness, chewiness, gumminess increased with higher amounts of P. frutescens powder, whereas springiness decreased. The antioxidant activities of fried yakgwa measured based on DPPH scavenging activity were higher than those of baked yakgwa with 0%~0.2% P. frutescens powder and lower than those of baked yakgwa with 0.3%~0.4% P. frutescens powder. In the sensory evaluation, baked yakgwa with 0.1% addition of P. frutescens powder showed the highest preference in terms of overall acceptance, and 0% addition of P. frutescens powder showed the highest preference in terms of color and flavor. These results suggest that P. frutescens powder may be a useful ingredient in baked yakgwa to improve quality and sensory properties.

In 2020, about 132 million m³ of aggregate was produced in Korea. Of the total domestic aggregates produced in 2020, about 33.3 % was sand and about 66.7% was gravel. It estimated that of the 132 million m³ of aggregates in Korea in 2020, about 52% was produced by screening crushed aggregate, by 36% by forest aggregate, 3% by land aggregate, 5.6% by sea aggregate and 2.5% by washing each other, and 0.4% by river aggregate. This indicates that screening crushed aggregate and forest aggregate are the main producers of domestic aggregates. Leading producing metropolitan cities were Gyeonggi-do, Gyeongsangnam-do, Chungcheongbuk-do, Gangwon-do, Chungcheongnam-do, Incheon in order decreasing volume, which together accounted for about 72.4% of total product. In 2020, aggregates were produced in 153 cities, about 67% of the 231 cities of Korea, 38 local governments have developed aggregates of more than 1 million m³, and the combined production of the 38 cities accounted for about 65% of national total. This means that the aggregate extraction trend of local governments is becoming larger and more concentrated. In 2020, at 153 local governments, a total of 889 operations produced aggregates with 420 operations by permission, 469 operations by declaration. A review of production by size of operation indicated that about 17 million m³ (12.8% of the total aggregate) was produced by 14 operations reporting production of more than 1 million m³. In about 420 operations, the maximum period of permit is 32 years to at least 2 months. When the remaining period of permit is taken into account, only about 55% of active operations can be developed the aggregate after 2021. In order to maintain the permitted aggregate volume by 2020 level, it will be necessary to obtain an extension permit or find new operation sites for at least 200 or more operations.

The purpose of this study identifies the production of aggregate every year, and is to understand the supply and demend prospects. In 2021, the total of 135 million m³ of of aggregates was produced in Korea, a slightly increase from the total production of 2020. Of these, about 47 million m³ of sand and about 88 million m³ of gravel were produced. About 46% of total quantity of aggregates were produced with permission and the rest were aggregates produced after declaration. It estimated that of the 135 million m³ of aggregates in Korea in 2020, about 49.6% was produced by screening crushed aggregate, by 36.8% by forest aggregate, 2.6% by land aggregate, 6.8% by sea aggregate and 2.6% by washing each other, and 0.2% by river aggregate. This indicates that screening crushed aggregate and forest aggregate are the main product as in 2021. Leading producing metropolitan governments were Gyeonggi-do, Chungcheongnam-do, Incheon, Gyeongsangnam-do, Chungcheongbuk-do, Gangwon-do, Jeollanam-do, Gyeongsangbuk-do in order decreasing volume. In 2021, aggregates were produced in 148 local governments, and The 10 leading producing local governments were, in descending order of volume, Hwaseong, Ongjin, Paju, Pocheon, Gwangju, Youngin, Cheongju, Gimhae, Anseong, west EEZ. The combined production of the 10 leading local governments accounted for 30% of the national total, and. 47 local governments have produced aggregates of more than 1 million m³ each other. In 148 local governments that produced aggregate, a total of 805 active operations produced aggregate with 372 operations by river, land and forest aggregate, 433 operations by selective crushed and washing aggregate.

The comparison of the capabilities of cell growth of four different kinds of commercially available microcarriers was carried out by culturing anchorage-dependent animal cells, Vero-6, in a spinner flask. Using 3 g/l of Cytodex 3, the maximum final cell density was about $1.4{\times}10^6$ cells/ml and increased up to $2.0{\times}10^6$ cells/ml by increasing microcarrier concentration up to 5 g/l. The macroporous collagen microcarriers, VX-100, informatrix, and Cultispher-G showed the final cell concentration of $4{\times}10^6$ cells/ml, $2.1{\times}10^6$ cells/ml, and $3.2{\times}10^6$ cells/ml, respectively at the microcarrier concentration of 5g/1. According to this result, VX-100 showed better cell growth than informatrix and cultispher-G and also showed about 2 fold increase in final cell density comparing to Cytodex 3 solid bead. When the intermittent bead-to-bead transfer technique was introduced in the culture using Cytodex 3 bead and cultispher-G, the result was very successful and the cells grew out very well. The recovered cells by dissolving collagen microcarrier using collagenase enzyme were mostly viable and grew out very well on the surface of the fresh microcarriers.
