연간 어획량으로 볼 때 오징어는 다른 어종 못지않게 중요한 종류이다. 오징어는 몸통뿐 아니라 내장과 간장 또한 이용가치가 매우 뛰어남에도 불구하고 그동안에는 사료용으로만 약간 사용되고 나머지는 대부분 폐기하였다. 본 연구에서는 이들 간장의 이용도를 넓힐수 있는 기초자료를 확보하고자 간장 중 일반성분과 지질 클래스의 변화를 월별로 조사하였다. 우선, 주문진항에서 4월에서 10월까지의 매월 한차례씩 살아있는 오징어를 구입하여 이들의 체중과 체장, 그리고 내장과 간장의 무게를 재고, 간장은 일반성분과 지질분석을 하였는데, 월별 체중 및 체장은 7월을 기점으로 여름철에 증가하며 체중도 같은 경향을 나타내었다. 그리고 간장의 무게도 체중의 증가와 비례하여 증가하였다. 비만도는 체장의 증가율에 비해 체중의 증가율이 높은 5월이 비만도가 가장 높았다. 같은 기간 중 일반성분의 변화를 보면, 수분은 대체로 감소하는 경향이고 단백질은 7월에서 9월 사이에 증가하는 경향을 보였다. 지질은 단백질과는 반대로 7월에서 9월 사이에 감소하는 경향을 보였으며, 회분은 매월 일정한 값을 나타내었다. 이러한 결과로 어체의 성장이 활발한 여름철에 단백질의 양이 증가하고 반면에 지질의 함량은 감소하는 것으로 나타났다. 한편, 지질 클래스에서 단순지질의 경우 NL은 봄철에서 가을로 가면서 점차 증가하는 경향을 보였고, 반면 S, PL은 감소하는 경향을 보였다. PL에서는 대부분 PC만이 검출되었으며, 계절적으로는 봄에서 가을로 갈수록 감소하는 경향을 보였다. Squid is one of the most popular species over the East coast of Korea and sold as raw or processed one at the market. However, the liver and intestine occupied more than 20% of whole body are discarded wastefully at present. At this point of view, we analyzed lipid classes and fatty acid composition of liver, and tried to develop the utilities on the useful components of liver and intestine of squid. Alive squids were collected at the port of Jumunjin, Kangwon-Do, Korea, from April to Oct., 1988, and measured the body length, body weight and liver weight. Chemical composition of liver was analyzed by general method. Moreover, lipid class of total lipid was analysed using Iatroscan. As a results of this study, body weight, body length and liver weight increased after July, and hepatosomatic index(HSI) increased after May. Moreover, condition factor was maintained at moderate level after May. Among chemical components, water content had negative correlation with lipid and concentrations of protein and ash were not changed remarkly. In analysis of lipid class, it was proved that neutral lipid(NL) fraction of total lipid(TL) contained triacylglyceride(TG), sterol ester(SE) and free fatty acid(FFA) while polar lipid (PL) fraction of TL contained phosphatidylcholine(PC) dominantly.

The Anaerobic-Oxic process is a modified activated sludge process that combines Anaerobic and Oxic section in sequence. This process has a merit which is the simultaneous removal of rrganic matter, nitrogen and phosphorus. The conclusions are as follows. ; The COD_(Cr) removal efficiency by the Anaerobic-Oxic process was 95.8%. Almost all of the COD_(Cr) was removed in an anaerobic tank. The COD_(Cr) removal rate by the Anaerobic-Oxic process was little better than that of standard activated sludge process(89.1%). The PO₄-P removal rate by the Anaerobic-Oxic process was 49.48% showing slightly higher dfficiency than that of standard activated sludge process(33.1%). It is considered that the Anaerobic-Oxic process is effective in 'the removal of phosphorus. It can be seen that phosphorus removal microbes in MLSS released phosphorus in anaerobic tank and phosphorus was up taken into sludge in aerobic phase.

The surface rolling method which is one of the plastic deformation processes makes good surface roughness with reduction of diameter and increase of hardness. In this study, three NACHI 6000 ZZ bearing were used for surface rolling tool on a mild steel and high carbon steel. The objective of this study is to investigate the effect of rolling on surface roughness, however the auther also observed the reduction of workpiece diameter and hardness increase of the surface. By this study the following results have been obtained with the mild steel and high carbon steel. 1. The surface roughness is affected by the factors such as elements of rolling speed, feed, and the applied force. 2. The surface roughness increased when rolling speed increased and when rolling speed is 12 m/min and feed is constant (0.36 mm/rev) the finest surface roughness has been produced for mild steel and high carbon steel. 3. When the rolling speed is fixed (12m/min from item 2), the slower the feed the better roughness has been obtained. When feed was 0.261 m/min the roughness was (0.18μRa∼0.22μRa) for mild steel and for high carbon steel when the rolling speed was 5m/min and feed was 0.36 mm/rev, the roughness of 0.39μRa∼0.42μRa has been obtained. 4. The finest surface roughness has been obtain when the applied rolling force is 0.5 Kg/mm and 0.56㎏/mm for mild steel and high carbon steel respectively.

백순기,김전희 동신대학교 환경연구소 1998 환경연구 Vol.3 No.1

동복호의 효율적인 수질관리를 위해 수온, pH, 탁도, 투명도, DO, 전기전도도, COD, SS, T-N, T-P, 클로로필-a등 10개 수질항목을 대상으로 5년간의 월별 수질변동 특성을 분석하고, N:P ratio와 투명도, T-p, 클로로필-a의 변수를 이용한 TSI를 이용하여 호수의 영양상태를 파악하였다. 동복호의 1993년부터 1997년까지의 5년 동안 수질인자 변동특성은 동복호의 전체적인 유기물 양이 시간의 흐름에 따라 조금씩 증가하는 경향을 보이고 있으며, 계절변동에 따라 수질환경이 변화함을 보여주었다. N:P ratio를 이용하여 동복호의 영양 정도를 판정해볼 때 2지점 모두에서 질소보다는 인의 제한이 많았으며, 계절별로는 여름과 겨울보다 봄과 가을의 N:P ratio가 높은 것으로 나타났다. 투명도, chlorophyll a, and total phosphorus에 대한 관계를 간편하게 측정하는 방법으로 Carlson TSI가 있으며 다음의 공식을 이용한다. TSI(SD) = 60-14.41 InSD (m) TSI(Chl-a) = 9.81 In Chlorophyll a(㎍/L) + 30.6 TSI(TP) = 14.42 Ln Total phosphorus (㎍/L) +4.15 TSI 값의 범위에 따라 보통 영양상태 등급으로 분류되어지는데, 40~50사이의 범위는 중영양 상태, 50보다 큰 값은 부영양 40보다 작은 값은 빈영양 상태로 분류되어진다. 따라서 Carlson TSI를 이용하여 동복호의 영향상태를 판정해볼 때 TSI(T-P)의 경우는 빈영양 상태와 중영양 상태로 분류되었고, TSI(SD)와TSI(Chl-a)는 중영양 상태와 부영양 상태로 분류되었고 특히 여름철에 중영양 상태와 부영양 상태로 분류되는 것으로 판정되었다. As needed for effective water quality control at Dongbok Reservoir, we have characterized water quality variation based on five year long monthly survey (1993-1997) of the water at two sampling sites on 10 variables including temperature, pH, SD transparency, DO, conductivity, COD, SS, T-N, T-P and chlorophyll a. Also, the tropic state of the Reservoir was evaluated by TSI based on N:P ratio and TSIs for Secchi Disk, T-P and chlorophyll a. During 1993-1997 overall organic content of the Reservoir gradually increased and seasonal variations of the aquatic environment were noticed. The N:P ratios from the two sites showed phosphorous rather than nitrogen was limiting, and higher ratios in springs and falls than in summers and winters. In this study, Carlson TSIs (shown below) for SD, chlorophyll a and total phosphorous were used to determine the tropic state of the water. TSI(SD) = 60 - 14.41 In SD (m) TSI(Chl - a) = 9.81 In Chlorophyll a (㎍/L) + 30.6 TSI(TP) = 14.42 Ln Total phosphorus (u㎛/L) + 4.15 Tropic state of any water is determined based on its TSI value; 40-50 for mesotrophy(moderate productivity), above 50 for eutrophy(high productivity) and below 40 for oligotrophy(low productivity). Dongbok Reservoir was classified as hypotrophic through eutrophic based on TSI(T-P); but mesotrophy through eutrophy based on TSI(SD) and TSI(chl-a). In summers especially, mesotrophy and eutrophy appeared frequently.

김성동,김전희,염승렬,백순기 동신대학교 환경연구소 1997 환경연구 Vol.2 No.1

BOD, 질소, 인 등이 다량으로 함유된 고농도 유기성 폐수는 BOB, 인, 질소 등 일부 오염물질의 농도가 현저하게 높거나 C/N비의 균형이 좋지 않은 특성 때문에 처리가 곤란할 뿐만아니라, 적정한 처리공정을 도입하는 것 또한 어려운 실정이다. 이에 따라 고농도 유기성 폐수 배출시설중 화학공장의 폐수를 처리대상 폐수로하여, 각각의 공정에서 배출되는 다른 성상의 폐수를 합한 원폐수를 초음파를 이용하여 무화(霧化 : fogginess)시킨 후 무화 전후의 BOD, COD, SS, N-H과중금속의 제거율을 분석한 결과, BOD, 55, N-H의 제거율은 높았으며 중금속의 제거에는 영향을 미치지 않는 것으로 나타났다. High concentration organic wastewater has been discharged out of industries. These industries are food industries, chemical industries, fiber industries, spinning factories, paper mill manufactories or night soil and stock breeding. Its wastewater was treated to fogginess using Ultrasonic Wave. Due to development of wastewater treatment technique, it is investigated by technique previous to the treatment. Acording to fogginess frequency, it was analysised variation of pollutants concentration. The conclusions are as fallows. Most pollutants were removed by fogginess using Ultrasonic Wave, while heavy metals were not removed Removal effect of BOD, COD, SS, N-H, T-N, T-P developed a tendency to decrease according to frequency.

박명숙,최희전,박해선,권순경 德成女子大學校 藥學硏究所 2002 藥學論文誌 Vol.13 No.1

For the development of new synthetic method for unnatural amino acid esters, alkyl α-anilinophenylacetates 4a-i were synthesized through base-catalyzed hydrolysis of 1,5-diphenylhydantoins 1a-b in methanol and O-alkylation of sodium α-anilinophenylacetate 3 with alkyl halides in DMF. Even though hydrolysis of hydantoin ring was undertaken under about 30-40℃ in methanol, the hydantoic acid sodium salt 2 was continuously converted to the sodium α-anilinophenylacetate 3. All synthetic process from hydantoin to alkyl α-anilinopheny lacetates could be carried out in one-pot without isolation of intermediates.
