본 연구에서는 Ross strain-208 브로일러 수컷 36,800 수를 기본 사료만 급여한 대조구와 기본 사료에 0.3% 점토 광물질 발효 산물을 첨가 급여한 처리구로 나누어 5주간 사양 시험을 시행하였고, 사육 후 육계의 최종 체중 및 일당 증체량, 육성율, 사료 섭취량, 사료 효율, 생산 지수 등에 미치는 영향을 조사하였다. 그 결과, 최종 체중은 점토 광물질 발효 산물을 0.3% 첨가 급여한 처리구가 대조구에 비해 유의성은 없으나 약 18.5% 증가하였고, 일당 증체량은 약 18.2% 유의하게 증가한 것으로 나타났다(p<0.05). 사료 섭취량과 처리구가 대조구보다 유의하게 21.4% 증가하였고, 사료 효율은 유의성은 없으나 약 2.7% 증가한 것으로 나타났다. 특히 육성율과 생산 지수는 처리구가 대조구에 비해 유의하게 각각 4.4%와 4.9% 증가하였다(p<0.05). 또, ND(뉴캐슬병)와 IBD(전염성 F낭병)의 백신을 음용 투여하였을 때의 항체 역가는, 0.3 % 점토 광물질 발효 산물 첨가구가 대조구에 비해 유의성은 없으나 각각 13.8%와 15.7% 높은 것으로 나타났다. 이상의 결과로부터 점토 광물질 발효 산물의 첨가급여는 육계의 생산성과 면역 기능을 증진시켜 항생제를 저감한 친환경적인 고품질 육계 생산에 도움이 될 것으로 사료되었다. A feeding trial was conducted to study the effects of dietary supplement of fermented clay mineral (FCM) on the growth performance and immune stimulation in broiler chickens. A total of 36,800 broilers, (of) Ross strain-208, were randomly allotted into 2 experimental (diet) groups. Control group was fed the basal diet (corn-soybean meal based), and treatment group was fed the natural clay mineral that was fermented with aboriginal microorganisms at $37^{\circ}C$ for 72 h. Feed and water were provided ad libitum throughout the experiment for 5 weeks of experimental feeding period. Daily weight gain of treatment group fed 0.3% fermented clay mineral was significantly increased in comparison with control group. Feed intake of treatment group was significantly increased 21.4% (p<0.05), and feed efficiency was also increased 2.7% compared to control group. Especially, growth rate and production index of treatment group were significantly higher as much as 4.4% and 4.8%, respectively, than those of control group (p<0.05). By the feeding of dietary 0.3 % FCM, the antibody productions against Newcastle Disease and Infectious Bursal Disease antigens were shown to increase 13.8 % and 15.7 %, respectively, more than control group chickens. From these results, it appears that the supply of fermented clay mineral at 0.3 % level in the broiler chicken diet could enhance the growth performance and immune stimulation of broiler chickens.

The growth patern and the seasonal changes in nutrient contents of Humulus japonicus wereinvestigated. Stem length of H. japonicus reached the maximum from 240 to 260 Julian date and the median value was found at 255 Julian date. The maximum leaf area was observed from 235 to 248 Julian date and the median value was at 240 Julian date. The maximum growth rate of the stem length ranged from 205 to date in the growth rate of the stem length and leaf area was 212 and 205 Julian date, respectively. The growth rate of H. japonicus was related to rainy season and precipitation. Phosphorus and sodium contents of H. japonicus were correlated with maximum potential rate of relative growth. Although stem biomas of H. japo-nicus was 1.5∼3.5 times larger than that of leaf, N content of the leaf (4.48∼5.27%) was about 2 times higher than that of the stem (2.0∼ H. japonicus in sumer. This result provides valuable information for apropriate timing for the removal of H. japonicus.

주은정,최명걸 (사)한국컴퓨터그래픽스학회 2020 컴퓨터그래픽스학회논문지 Vol.26 No.5

We present a supervised learning method that estimates the simulation parameters required to simulate the fabric from the static drape shape of a given fabric sample. The static drape shape was inspired by Cusick’s drape, which is used in the apparel industry to classify fabrics according to their mechanical properties. The input vector of the training model consists of the feature vector extracted from the static drape and the density value of a fabric specimen. The output vector consists of six simulation parameters that have a significant influence on deriving the corresponding drape result. To generate a plausible and unbiased training data set, we first collect simulation parameters for 400 knit fabrics and generate a Gaussian Mixed Model (GMM) generation model from them. Next, a large number of simulation parameters are randomly sampled from the GMM model, and cloth simulation is performed for each sampled simulation parameter to create a virtual static drape. The generated training data is fitted with a log-linear regression model. To evaluate our method, we check the accuracy of the training results with a test data set and compare the visual similarity of the simulated drapes. 본 연구에서는 주어진 옷감 시료의 정적 드레이프 모양으로부터 해당 옷감을 시뮬레이션하기 위해 필요한 시뮬레이션 파라미터를 추정하는 데이터 기반 학습법을 제시한다. 정적 드레이프의 모양을 형성하기 위해 의류 산업계에서 옷감을 물성에 따라분류하기 위해 사용하는 쿠식 드레이프 (Cusick’s drape)에서 착안한 방법을 사용한다. 학습 모델의 입력 벡터는 특정 옷감의정적 드레이프 모양에서 추출한 특징 벡터와 옷감의 밀도 값으로 구성되고, 출력 벡터는 해당 드레이프 결과를 도출하는 여섯가지 시뮬레이션 파라미터로 구성된다. 실제에 가깝고 편향되지 않은 학습 데이터를 생성하고자 먼저 400가지의 실제 니트옷감에 대한 시뮬레이션 파라미터를 수집하고 이로부터 GMM (Gaussian mixture model) 생성 모델을 만든다. 다음, GMM 확률분포에 따라 대량의 시뮬레이션 파라미터를 무작위 샘플링한다. 샘플링된 각각의 시뮬레이션 파라미터에 대해 옷감 시뮬레이션을 수행하여 가상의 정적 드레이프 결과를 만들고 이로부터 특징 벡터를 추출한다. 생성된 데이터를 로그선형회기(log-linear regression) 모델로 피팅한다. 학습의 수치적 정확도를 검증하고 시뮬레이션 결과의 시각적 유사도를 비교하여제시된 방법의 유용성을 확인한다.

주은정,정성훈,윤세창,맹소진,윤경식,정인원,이규영,안용민,강웅구,김용식 대한정신약물학회 2003 대한정신약물학회지 Vol.14 No.2

목적: 정신분열병에서 가장 흥미로운 신경전달물질 중 하나인 도파민대사 과정에서 주요 역할을 하는 COMT 유전자와 정신분열병의 관련성을 규명하고자 하였다. 방법: (1)한국인 정신분열병 환자에서 특이적으로 나타나는 단일염기다형성 부위가 존재하는지 알아보기 위하여 COMT 유전자 전체 서열 중 exon을 대상으로 F-CSGE방법을 이용하여 정신분열병 환자 50명에서 단일염기다형성 부위를 조사하였다. (2)정신분열병 환자군 218명 및 정상대조군 199명을 대상으로 COMT 유전자에 존재하는 다섯 가지 단일염기다형성에 대하여 SNaPShot 방식으로 유전자형을 조사하였다. 대립유전자빈도, 유전자형빈도와 일배체형 빈도를 구하여 정신분열병 환자군과 정상대조군 간의 차이를 비교 분석하였다. 결과: (1)COMT exon 부위에서 한국인 특유의 의미 있는 단일염기다형성은 발견되지 않았고, 외국에서 보고된 바 있는 일곱 가지 단일염기다형성 부위가 발견되었다. (2)대립유전자 빈도, 유전자형 빈도 및 일배체형 빈도에서 정신분열병 환자군과 정상대조군 간에 유의한 차이가 없었다. 결론: 본 연구에서는 COMT 유전자에 존재하는 다섯 가지 단일염기다형성과 한국인 정신분열병환자의 DSM-IV 진단 간에는 관련성을 찾을 수 없었다. Objective: This study aimed to explore genetic relation between schizophrenia and COMT gene which plays an important role in metabolizing dopamine, one of the most intriguing neuro-transmitters for schizophrenia. Methods: (1)Single Nucleotide Polymorphism(SNP) on exons of COMT gene was searched by F-CSGE(Fluorescent-Conformation Sensitive Gel Electrophoresis) method with 50 patients with schizophrenia to look for any SNP unique to Korean patients with schizophrenia. (2)Genotyping was done for five SNPs on COMT gene for 218 patients with schizophrenia and 199 normal controls by SNaPShot method. Allele frequencies, genotype frequencies and simulated haplotype frequencies were compared between patients with schizophrenia and normal controls. Results:(1) No unique SNPs for Koreans was found on exons of COMT gene and seven SNPs were found, all of them are already reported to be found in other ethnic groups. (2) No significant difference between patients with schizophrenia and normal controls in terms of allele frequencies, genotype frequencies and haplotype frequencies was found in our sample. Conclusion: Genetic association between five SNPs on COMT gene and DSM-IV diagnosis of schizophrenia among Koreans was not able to be found in this study.

The present study undertaken to investigate the interrelationship among their regular dietary fatty acid intake, body fat content(BFC), and plasma lipid fractions(PLF) of middle-aged Korean women. Forty-nine women(age 30 to 49) participated in this study in which the aim was to determine their total nutrient intake per day, BFC and PLF, and to analyse the intercorrelations of these. Strong correlation was seen among their body mass index, mid-upper-arm-circumference, and BFC which were positively correlated with plasma total lipids(TL) and triglycerides(TG). Dietary myristic acid and lauric acid were positively correlated with both total cholesterol(TC) and LDL-cholesterol(LDL-C) in plasma. Palmitic acid, stearic acid, oleic acid, and total monounsaturated fatty acid(MUFA) were negatively correlated with HDL-cholesterol(HDL-C). Although dietary total saturated fatty acid(SFA) was not correlated with TC and LDL-C, it was positively correlated with TL and TG in plasma. However, dieary n-3 polyunsaturated fatty acid(PUFA) in regular Korean diet was not correlated with any of lipid fractions in plasma which might he due to the high ratio of n-6/n-3 in their diet. From the above results, it was concluded that plasma lipid fractions were modulated by their dietary nutrients, especially the types of the fatty acids. Dietary SFA and MUFA intake not PUFA are strongly correlated with LDL-C and HDL-C in the Korean diet. This may relate to the frequency of coronary heart disease in the age group.

초등 예비교사의 생물에 대한 특정 공포증 실태 및 생물 교수 효능감과의 관계

주은정 韓國生物敎育學會 2014 생물교육 Vol.42 No.3

In this study, pre-service elementary teacher's specific phobia and its relationship to biology teaching self-efficacy were investigated. For the study, I surveyed 90 pre-service elementary teachers' SUD (subjective Units of Distress level) and biology teaching self-efficacy. Then, several pre-service teachers having specific phobia were interviewed in-depth to explore their concern about specific animal phobias and alternative teaching methods about living things. The result showd that the animals which many pre-service elementary teachers had specific phobias about were; centipedes, snakes, spiders, and insects. Pre-service teachers' SUD had a negative correlation with science and biology teaching self-efficacy. They were concerned about how student would thing them as teacher. Some had been willing to teach living thing units disregarding their fear. Other pre-service teachers said they would teach in using model or media about living things instead of hands-on activity. The others didn't have any alternative teaching method. The pre-service elementary teacher's specific animal phobia can effect negatively on teaching biology with living organism, because their phobia had negative relationship with the biology teaching self-efficacy.

“Breakthrough” of psychosis despite good compliance of antipsychotics medication for a long time is a major obstacle to the treat- ment of schizophrenia, whether the mechanism is caused by dopamine hypersensitivity or insufficient dose of antipsychotics. Researchers advocating “Dopamine Supersensitivity Psychosis” (DSP) emphasize to avoid excessive inhibition of dopamine 2 receptors from the beginning of treatment. On the other hand, researchers advocating “Breakthrough psychosis on Antipsychotic Maintenance Medication” (BAMM) in which psychosis recurs due to insufficient medication despite continuous administration of antipsychotics without non-adherence argue that dose of antipsychotics should be increased to enhance therapeutic effect. In patients using long-acting antipsychotics injection (LAI), non-compliance can be ruled out. We believe that in treating non-affec- tive psychosis, it is necessary to continuously maintain the lowest dose possible using the optimal dose considering the side effects of second-generation antipsychotics and the cycle and stage of psychosis, and the optimal formulation such as LAI

여대생들의 신체상의 다이어트가 섭식장애, 식이섭취량 및 사회심리적 요인에 미치는 영향

주은정,박숙희 동아시아식생활학회 1998 동아시아식생활학회지 Vol.8 No.4

Thinness has become a symbol for beauty, acceptance and competence for women in our society, and pressure to diet because of this unrealistic standard is one factor reponsible for the increasing incidence of eating disorder. Three hundred fifty college women in the Chonbuk area were surveyed from May to June 1998, to investigate the relationship among body image, eating disorder, dietary intakes, self esteem and sex role identity. This study identified a subgroup of women who were relatively satisfied with their body weight and who did not diet. This group was compared with subgroups of women who were dissatisfied with their bodies and either were or were not restrained eaters. The dissatisfied/dieting women had the highest BMI, binge eating disorder and night eating syndrom, had significantly lower calorie, protein, iron, vitamin B₁, and vitamin B₂ intake compared with the satisfied/non-dieting women. The dissatisfied/dieting women, who had lower self-esteem compared with the satisfied/non-dieting women, but the frequency of sex role identity was similga among the groups of women. BMI and binge eating disorder were positively correlated(r=0.157, p<0.01), but BMI and self esteem were negatively correlated (r=-0.202, p<0.01). Especially, binge eating disorder and self esteem were negatively correlated(r=-0.126, p<0.05).

주은정,강철인,김예진,정두련,백경란,송재훈 대한감염학회 2011 Infection and Chemotherapy Vol.43 No.2

Influenza-associated encephalopathy is rare in adults and the role of influenza virus in the pathogenesis of influenza-associated encephalopathy is unclear. We report a case of an adult patient who presented with typical clinical manifestations and magnetic resonance imaging findings of herpes simplex virus (HSV) encephalitis confirmed by positive PCR test in cerebrospinal fluid (CSF), and who was also PCR-positive PCR for H1N1 A/influenza in CSF and a nasopharyngeal swab. The results strongly suggest co-infection of the central nervous system. Given the significant implications for therapeutic interventions and infection control, A/H1N1influenza should be considered one of the possible etiologies of viral encephalitis when patients present with an influenza-like illness during an influenza
