Relative biological effectiveness of fast neutrons for apoptosis in mouse hair follicles
Hae-June Lee, Sung-Ho Kim* 대한수의학회 Journal of Veterinary Science 6 Pages
대한수의학회 Journal of Veterinary Science 2007, 제 8권 제 4호 4 335-340 (6 pages)
h after irradiation. The dose-response curves were analyzed using the best-fit curve model. The dose-response curves were linear-quadratic, and a significant relationship was found between the frequency of apoptotic cells and the dose. The morphological findings in the irradiated groups were typical apoptotic fragments in the matrix region of the hair follicle, but the spontaneous existence of apoptotic fragments was rarely observed in the control group. In the presence of an apoptosis frequency... -
Biological Rhythm in Livestock
Piccione Giuseppe and Caola Giovanni 대한수의학회 Journal of Veterinary Science 13 Pages
대한수의학회 Journal of Veterinary Science 2002, 제 3권 제 3호 1 145-157 (13 pages)
The animal time structure is a basic fact of life, no matter if one wants to study it or not. The time-dependent, mostly rhythmic, and thus to a certain degree predictable, variations of biochemical and physiological functions and of sensitivity and resistance to many environmental agents are often quite large and offer not only new insight into animal physiology and pathology but also diagnostic possibilities and therapeutic advantages. Chronobiology, chronophysiology and its subspecialities,... -
A Simple Dosing Scheme for Intravenous Busulfan Based on Retrospective Population Pharmacokinetic Analysis in Korean Patients
SangminChoe, GayeongKim, Hyeong-SeokLim, Sang-HeonCho, Jong-LyulGhim, JinAhJung, Un-JibKim, GyujeongNoh, Kyun-SeopBae, DonghoLee 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages

Busulfan is an antineoplastic agent with a narrow therapeutic window. A post-hoc population pharmacokinetic analysis of a prospective randomized trial for comparison of four-times daily versus once-daily intravenous busulfan was carried out to search for predictive factors of intravenous busulfan (iBu) pharmacokinetics (PK). In this study the population PK of iBu was characterized to provide suitable dosing recommendations. Patients were randomized to receive iBu, either as 0.8 mg/kg every 6 h... -
Nonlinear Regression Analysis to Determine Infection Models of Colletotrichum acutatum Causing Anthracnose of Chili Pepper Using Logistic Equation
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 3 17-24 (8 pages)
A logistic model for describing combined effects of both temperature and wetness period on appressorium formation was developed using laboratory data on percent appressorium formation of Colletotrichum acutatum. In addition, the possible use of the logistic model for forecasting infection risks was also evaluated as compared with a first-order linear model. A simplified equilibrium model for enzymatic reactions was applied to obtain a temperature function for asymptote parameter (A) of logistic... -

Application of Asymmetric Item Response Models to a Vertical Scaling Context
이소라(Lee Sora) 한국교육학회 교육학연구 20 Pages
한국교육학회 교육학연구 2022, 60권 7호 2 23-42 (20 pages)
inflection point of an S-shaped curve, functions more properly than other commonly used item response models in dealing with several measurement issues. Among asymmetric models, the logistic positive exponent (LPE) model of Samejima (2000) is focused on. This study mainly explores how asymmetric item response models can be extended to accommodate various psychometric applications through linking such as differential item functioning or computerized adaptive testing. From the simulation study, a... -
수학 학업성취도의 동질 성장모형과 변화 전환점 추적: 비선형 조각별 성장혼합모형의 적용
박희주, 류지훈 한국교육학회 교육학연구 32 Pages
한국교육학회 교육학연구 2022, 60권 4호 4 90-121 (32 pages)
종단연구에 있어 변화의 패턴을 찾아내어 성장을 예측하는 것이 가장 핵심적이라 할 수 있다. 그 변화의 패턴은 대부분 비선형의 형태로 나타나게 되는데, 본 연구에서는 비선형 모델 중 조각별 성장혼합모형을 활용하여, 이질적 성장모형의 존재가능성과 알려지지 않은 전환점을 찾아냄으로써 성장모형을 예측하고자 한다. 이를 확인하기 위해 베이지안 추정 방법과 최대우도법을 조각별 성장혼합모형에 활용하였다. 실증적 자료인 서울교육종단연구(SELS-2010) 데이터를 활용하여 학생들의 수학 학업성취도가 시간이 지남에 따라 어떠한... -
Kinetic and multi-parameter isotherm studies of picric acid removal from aqueous solutions by carboxylated multi-walled carbon nanotubes in the presence and absence of ultrasound
Soheila Gholitabar, Hasan Tahermansouri 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 2 14-24 (11 pages)
Carboxylated multi-wall carbon nanotubes (MWCNTs-COOH) have been used as efficient adsorbents for the removal of picric acid from aqueous solutions under stirring and ultrasound conditions. Batch experiments were conducted to study the influence of the different parameters such as pH, amount of adsorbents, contact time and concentration of picric acid on the adsorption process. The kinetic data were fitted with pseudo-first order, pseudo-secondorder, Elovich and intra-particle diffusion models.... -
Study on Antecedent Moisture Condition for Seolma Stream Basin
Ly Sidoeun, Shin Hyun Seok, Kim Duck Hwan, Kim Beom Jun, Kim, Hung Soo 한국습지학회 한국습지학회지 10 Pages

Curve number (CN), originally developed, compiled by ‘The Natural Resources Conservation Service (NRCS)’, and has been widely used throughout the world. However, there is the uncertainty of CN derived from the use of antecedent moisture condition (AMC)/Antecedent Runoff Condition (ARC). As in Korea where nearly 70% covered by mountainous area, it is still not sufficient handbook precedent to guide or support the estimation of AMC/ARC. The failure to develop formal criteria of applying AMC/ ARC...
