실내사육한 보리새우, Penaeus japonicus BATE 유생의 에너지 수지

朴起永 강릉대학교동해안지역연구소 1990 東海岸硏究 Vol.1 No.1

實驗室에서 飼育시킨 보리새우, Penaeus japonicus幼生의 에너지수지를 분석하여 섭이와 성장 및 대사에 따른 에너지흐름의 동태를 파악하였다. 보리새우는 전유생기간을 통해 0.56㎈의 에너지를 體成長에 사용하였다. 성장에 수반되어 탈피체로 손실된 에너지는 0.05㎈였으며, 전체 유생기간을 통해 0.52㎈를 호흡에 사용하였다. Zoea유생기의 총섭이량에 따른 에너지는 1.06㎈이고, mysis유생기는 5.32㎈로서 전유생기간 동안 섭이에너지는 6.38㎈이었다. Zoea유생기의 배설과 배출로 방출된 에너지는 0.77㎈이며, mysis유생기에는 4.49㎈의 에너지를 방출하여, 전유생기간 동안 5.26㎈의 에너지를 尿와 糞으로 배출하였다. 섭취한 먹이에 대한 同化效率은 17.62%이었다. 성장으로 전환된 에너지의 섭이에너지에 대한 백분율인 총성장효율(K₁)은 9.52%였으며, 성장으로 전환된 에너지의 동화에너지에 대한 백분율인 순성장 효율(K₂)은 54.04%이었다. 동화에너지가 體成長에 사용된 비율은 49.6%였으며, 동화에너지에 대한 대사 에너지의 백분율은 45.95%이었다. 유생기에서 탈피에너지 손실은 동화에너지의 4.45%를 차지하였다. The energy budget of the oriental brown shrimp, Penaeus japonicus BATE larvae reared in the laboratory from nauplius I to mysisⅢ was studied. Energy used by the reared shrimp larvae were calculated from data on feeding, growth, molting, and metabolism. The energy used by growth during the total larval stages was 0.56㎈. Molting energy loss was estimated to be 0.05㎈ during the total larval stages. Energy use in respiration was estimated to be 0.52㎈ during the larval stages. The energy intake from feeding was 1.06㎈ for the zoea-larval stage, 5.32㎈ for the mysis- larval stage, respectively. Energy loss by excretion during the total larval stages was 5.03㎈. Larvae assimilated 17.62% of ingested food, investing 49.6% of assimilated energy in somatic growth. The gross growth efficiencies(K₁) showed 9.52% for larvae, and the net growth efficiencies (K₂) showed 54.04% for larvae. Maintenance costs were estimated at 49.95% of assimilated energy in larvae. Molting loss was estimated about 4.45% of assimilated energy in larvae.

유영태,신호준,임기건 한국공작기계학회 2004 한국생산제조학회지 Vol.13 No.6

The welding characteristics of Inconel 600 Alloy using a continuous wave Nd:YAG laser are experimentally investigated. The major process parameters studied in the present laser welding experiment were the positions of focus, laser power and travel speed of laser beam. We measured the fusion zone size and its shape using an optical microscope for the observation of cross-sectional area. We performed two tests regarding the tension and the micro hardness for welding quality estimation. Then we measured residual stress in welds by electronic speckle pattern interferometry(ESPI). In conclusion, the optimum butt welding process parameters were 0.5mm focus position, 1.6kW laser power, 1m/min travel speed and 5.5ℓ/min assist gas discharge.

틸라피아의 웅성개체 생산에 관한 연구

朴起永 강릉대학교동해안지역연구소 1990 東海岸硏究 Vol.1 No.3

틸라피아의 수컷만을 생산하기 위하여 Oreochromis niloticus 치어에 웅성호르몬 처리에 의한 성전환율과 O. niloticus와 O. mossambicus 간의 종간 교배에 의한 수컷 생산율을 구하고, 호르몬 처리가 성장과 생존율에 미치는 효과를 조사하였다. 초기 치어기의 성분화가 일어나기 전 부화 후 7일째부터 MT를 30, 60 및 100ppm농도로 10∼40일간 처리하여 성전환율 90%이상의 수컷이 생산되었고, 처리시기가 늦을수록 수컷으로의 성전환율이 저조하였다. 그리고, 100ppm 처리 농도에서는 처리 시기가 늦어도 성전환율이 다소 높은 경향을 나타내었다. 잡종 O. niloticus(♀)와 O. mossambicus(♂)을 교배하여 66.9%의 수컷을 생산하였고 잡종 O. mossambicus(♀)와 O. niloticus(♂)을 교배하여 62.8%의 수컷을 생산하여 종간교배는 계통간에 잡종이라도 수컷생산에 효과가 있음을 알 수 있었다. 호르몬 처리가 끝난 직후 모든 농도별, 처리기간별 전장의 측정결과는 대조군과 유사하였고, 60, 100ppm 농도에서 40일간 처리군은 성장이 고르지 못하였다. MT처리가 끝난 다음 처리농도별, 기간별로 부화후 69, 90, 120일간 사육한 치어의 전장과 체중의 측정결과는 대조군에 비해 비교적 뚜렷한 성장증가를 보여 MT처리가 성장에 매우 양호한 영향을 미치고 있음을 알 수 있었다. MT처리한 O. niloticus의 부화 후 6개월 동안 사육한 생존율은 89.3∼93.7%였으며, 치어 초기에는 수컷이 암컷보다 잘 죽는다는 것을 알 수 있었다. The effectiveness of 17α- methlytestosterone(MT) for sex reversal, growth, and survival in Oreochromis niloticus and practical aspects of the production of all male tilapia hybrid(O. niloticus×O. mossambicus) were studied in culture experiments. Wild-spawned fry were treated with 30, 60 and 100㎍ ?? diet for 10, 20, 30 and 40 days. The fish were grown on for 180 days after the hormone treatment period in indoor fish culture tanks. When treated with 30, 60 and 100㎍ ?? diet for 10, 20, 30 and 40 days in fry 7 days after hatching, the percentage of males was more than 90%. And tilapia treated with 30 and 60㎍ ?? diet for 30 and 40 days showed all males. In interspecific crosses of O. niloticus females and males with O. mossambicus females and males, the percentage of males ranged from 62.8 to 66.9%. Growth of tilapia treated with MT by treatment concentration was similar to that of untreated fish through all treatment periods. And tilapia treated with 60 and 100㎍ ?? diet for 40 days showed irregular growth. Growth of tliapia treated with MT for 60, 90 and 120 days significantly increased compared with control. It is suggested, therefore, that 17α- methlytestosterone reflects the growth of tilapia. Survival rates of O. niloticus treated with MT for 6 months ranged from 89.3∼93.7%.

류영욱,배현숙,성진효,김동기 조선대학교 구강생물학연구소 2003 Oral Biology Research (Oral Biol Res) Vol.27 No.1

According to the increase of the number of dental clinics and the level of the patient's recognition about oral health care, the need for effective clinical management to provide proper oral health care service to the patients has arisen. Many patients has selected the dental clinics based on self estimation or other recommendation. Therefore the main reasons for selecting the dental clinic by the patients needed to analyze, So we conducted the survey which prepared questionnaire were provided to 700 subjects and collected data related to the factors for patients to select the dental clinics. The results were as follows : 1. In the view of access, the place easy of access and parking capacity was important to the degree of 43.0% and 30.8%, respectively. 2. In relation to the dentist, the quality of treatment and the trust was important to the degree of 80.7% and 71.3%, respectively. 3. Modern clinical facility was occupied 65.5% in the basic environment factors. 4. In the basic factors, kindness and cleanliness was 76.6% and 76.7%, respectively, and it showed that these factors were more important than the number of the clinicians and comfort of the waiting room. 5. In relation to the satisfaction of treatment, cheaper treatment cost, decreased waiting tine, the variety of treatment tine and various payment method were important to the degree of 51.8%, 48.4%, 42.8% and 39% in order.

For the purpose of the succession of the Korean traditional housing, this study analizes the Yang-Teag-Non(陽宅論) which is the spatial theory of the ancesto's. The Yang-Teag-Non is to establish the most suitable house for the life of man with adaptation of house spacial organization to the netural order which is the theory of I-Ching(陽) The principle is to lay out each unit (room & yard) step by step in accordance with the action and change of the Yin Yang forces (陰陽氣) and the Five forces (五氣). Traditional house space of the Yang-Teag-Non is consisted not with the expansion of one house into a mass but with the connection of the unit space in order which has human scale. The properties of the space has organism and varieties as the space is divided into, and has hierarchical order which is a vertical order, and closed order which is a horizontal order.

6 시그마 기법을 이용한 임상약동학 자문 업무의 효율성 개선 : 신속성과 정확성을 중심으로 Focusing on Speed and Accuracy of CPS

김민영,박효정,박향미,손기호,최경업,박영하 한국병원약사회 2001 병원약사회지 Vol.18 No.2

연구 배경 : 적정한 약물요법을 순발력 있게 시행하기 위해서는 CPS 업무가 신속, 정확하게 수행되는 것이 필수적임에도 불구하고 지금까지 CPS 업무의 신속성, 정확성을 향상시키기 위한 객관적인 업무 표준은 물론 그의 측정까지도 전무한 실정이었다. 이에 수요자인 의사의 측면에서, CPS 자문결과의 신임도에 영향을 미치는 업무의 순발력과 정확성을 향상시키기 위해 CPS 업무의 신속성, 정확성에 영향을 미치는 요인을 파악, 분석하고 이를 향상시킬 수 있는 업무 표준을 개발하는 것을 목표로 6-Sigma 기법을 사용하여 본 연구를 진행하였다. 방 법 : CPS 업무의 신속성 평가를 위해 전체 업무 과정과 부분별 업무 과정에 대한 소요 시간을 측정하였고, 정확한 평가를 위해 예측되는 Cpeak와 실제 측정된 Cpeak를 비교하였다. CPS 업무에 대해 6-Sigma 기법을 사용하여 개선이 필요한 사항을 파악하고 이에 대한 개선활동을 한 후, 개선 활동 전과 후의 CPS 업무의 신속성과 정확성의 σ 수준을 각각 측정하여 이의 향상 정도를 잠재적인 경제적 이익으로 환산하였다. 결 과 : 신속성은 제 1차 자료수집 기간(대조군, 현황 파악 기간) 중 총 소요시간은 평균 930.6±583.2이었으며, 채혈-검체 접수 : 140.4±8705분, 검체접수-약물농도 결과보고: 48.4±23.1분, 결과보고-CPS 보고서 작성 : 741.8±510.6분으로 측정되었다. σ 수준은 총 소요시간의 경우는 0.56σ, 단계별로는 각각 0.45σ, 5.70σ, 0.30σ이었다. 제 2차 자료수집 기간(개선군, 개선활동 평가 기간) 중 총 소요시간은 평균 659.1±344.1분이었고 단계별로는 각각 92±66.2분, 48±28.0분, 518.9±340.7분이 소요되었다. σ 수준은 총 소요시간은 1.75σ이고, 단계별로는 1.32σ, 4.70 σ, 1.10σ로서 총 소요시간과 단계별 소요시간이 1차 자료수집기간에 비해 향상되었다. 정확성 측면에서는, 대조군의 경우, 예측 Cpeak와 실측 Cpeak의 차이는 평균은 0%, 분산 ±27.10%, σ 수준은 -0.56σ이었고 개선군의 평균과 분산 그리고 σ 수준은 각각 0%, ±15.10%, 0.14σ로 향상되었다. CPS 신속성, 정확성 향상으로 인한 경제적 이익은 정확성 측면에서 380만원/년, 신속성 측면에서 1350만원/년으로 총 1730만원/년의 비용절감 효과가 있었다. 결 론 : CPS 업무 흐름에 따라 CPS 효율성에 영향을 미치는 요인을 분석한 결과 CPS 효율성 향상을 위해서는 투약관련 의무 기록의 정확성, 임상병리 검사의 정도관리 향상, 그리고 관련 부서와의 원활한 업무 협조가 가장 중요하였다. The effectiveness of CPS (Clinical Pharmacokinetics Service), one of pharmacist's clinical services, was emphasized by many studies since 1985 it was introduced Korea about. But in the view of clinicians (medical doctors), customers, it's convenience or reliability was not properly evaluated for applying it to patient's care. To improve quality of Clinical Pharmacokinetics Service (CPS), the speed and the accuracy of CPS, the key points of efficiency in CPS, were evaluated by using 6-Sigma method. The speed of CPS was evaluated using total hours it took from blood sampling by a nurse to sending a CPS report to the patient's chart by a clinical pharmacist. Total hours were divided into blood sampling-to-sampling registering, sampling registering-to-C_(peak) result reporting, and C_(peak) result reporting-to-pharmacist's CPS report. The accuracy of CPS was evaluated by the difference between expected C_(peak) and measured C_(peak). Then the speed and the accuracy of CPS were expressed as σ level. After the campaign for improvement by Six Sigma method, the speed was improved by 1.19σ (before and after the campaign; 0.56σand 1.75σ, respectively) and the accuracy was improved by 0.7σ (before and after the campaign, -0.56σand 0.14σ, respectively). Exact recordings of dosing time, drug infusion hours and blood sampling time were shown to have profound effect on the accuracy of CPS. The improvement in the speed and the accuracy of CPS could produce potential financial benefit of U.S.$ 15,300 a year. There have not been studies on evaluating and objectifying as numerical value for the speed and the accuracy of CPS; thus, 6-Sigma method for improving efficiency in manufacturing process was applied to CPS process by expressing as σlevel. The speed and the accuracy of CPS could be improved by tightly controlling many factors related to CPS efficiency.

김동기,이영태,김기향,김성만,김대경,김두일,김동수 白中央醫療院 2005 仁濟醫學 Vol.26 No.1

Moyamoya disease is an occlusive intracranial arteriopathy with an abnormal cerebral vascular collateral networks. Although this disease is known to be associated with stenosis of extracranial arteries, such as the renal artery, a case associated with stenosis of the coronary artery is extremely rare. We report a case of coronary artery occlusive disease affected by Moyamoya disease. The patient was a 38-year-old female experiencing intermittent headache and exer tional chest pain. Cerebral MRI showed complete obstruction of both internal carotid arteries and abnormal cerebrovascular systems which confirmed Moyamoya disease. Coronary angiography showed a significant stenosis of left anterior descending coronary artery ostium with TIMI grade I collateral blood flow from the normal right coronary artery. After coronary artery stenting and medical treatment for headache, her subjective symptoms were relieved. In Moyamoya patient, an evaluation of the extracranial (especially coronary artery) vascular system should be considered if there are some evidences of coronary artery disease.
