재생(regeneration)의 어원은 유전자(gene)입니다. 다시 말해서 유전자를 다시 만드는 일, 바꾸는 일이 재생의 본래 뜻입니다. 원형, 시스템은 놔두고 외형만 바꾸는 것은 재생의 본질이 아닙니다. 유전자를 바꾸는 일은 결코 쉽지 않습니다. 게다가 이제까지 살아왔던 삶의 체계를 3년 만에 바꾸는 것은 더욱 어려운 일입니다. 도시재생이 도시재생사업만으로 달성될 수 있다면 그것은 재생이 아닌 재개발입니다. 결국 뉴딜사업은 재생을 위한 마중물의 역할이 되어야 합니다. - 『사북해봄마을 아카이브』(이용규, 2022, p. 6) 중 발췌 -

The techniques for Hg emission control usually involve the use of adsorbents. Among those adsorbents, activated carbon is currently being most widely used. However, the use of activated carbon is limited because of its high cost, poor capacity, low applicable temperature range, and its slow adsorption and regeneration rates. For that reason, use of TiO2 instead of activated carbon has been recently proposed for effective mercury emission control. In this study, the removal efficiency of vapor-phase elemental mercury by TiO2 irradiated using various light sources was investigated. The contacting surface area between mercury and adsorbents was increased by packing the adsorption bed with mixture of TiO2 and glass beads. A reactor was specially designed to increase the photocatalyst`s exposure to the light source. The results show more than 99% mercury removal efficiency for most of the light sources tested and close to 99% even under the solar light.

Candids kefyr CBS 834의 β-galactosidase를 cellulose triacetate에 고정화하였다. 효소를 고정화하기 위한 최적조건은 100㎖ methylene chloride에 10g의 cellulose triagetate를 용해한 액에 효소액 15%을 첨가하여 만든 후, 200 strokes/min으로 진탕반응했을 때 얻어졌다. 또한 섬유의 절단길이는 효소활성에 큰 영향을 주지 않았다. 고정화효소의 최적온도와 pH는 각각 50℃와 7.0이었고, 활성화에너지는 8,539 cal/mole이었다. ONPG를 기질로 하였을 경우 고정화 효소의 K_m과 V_(max)은 각각 7.4×10^(-5)M과 66.7 unit/㎎ protein이었고, 유당에 대한 K_m과 V_(max)은 3.3×10^(-4)M과 29.4 unit/㎎ protein이었다. 고정화 효소를 4℃에서 30일간 저장후 잔존활성과 3회 재사용후 잔존활성을 조사할 결과 각각 95%와 94%을 유지하였다. 고정화 효소 1g(190 unit)을 50㎖의 탈지유와 5% 유당용액에 첨가한 후 30℃에서 10시간 반응시켰을 때 각각 10%와 15%의 유당분해율을 보여주었다. β-Galactosidase from Candida kefyr CBS 834 was immobilized in the cellulose triacetate. The optimal condition for the immobilized enzyme was obtained by 15% of the enzyme solution added to 100㎖ of methylene chloride and 10g of cellulose triacetate. The length of fiber had hardly any an effect on the enzyme activity and the optimal condition for reciprocating water bath shaker was 200 strokes per minute. The optimal temperature and pH for the immobilized enzyme were 50℃ and 7.0, respectively. The activation energy for the immobilized enzyme was 8,539 cal/mole. The Km and Vmax of the immobilized enzyme, on ONPG were 7.4 × 10^(-5)M and 66.7 unit/㎎ protein, whereas those on lactose were 3.3 × 10^(-4)M and 29.4 unit/㎎ protein, respectively. The rate of remained enzyme activity for the immobilized enzyme stored at 4℃ for 30 days was 95%, and when reused for three times was 94%. When the skim milk (4.8% lactose) and 5% lactose solution of 50㎖ were reacted with the immobilized enzyme (190 unit) for 10hrs at 30℃, 10% of the lactose in skim milk was hydrolyzed, whereas 15% of the lactose in 5% lactose solution was hydrolyzed.
