The female moths of Lepidoptera comprising over 1,000,000 described species possess long-chain unsaturated alcohols or esters as the typical structure of potential sex attractants. In this experiment, various stereoisomers of C_(16)-unsaturated acetates were synthesized for potential sex attractants; e.g., CH₃(CH₂)_m^(++)CH=CH(CH₂)_nOR (m=0-12, n=1-13, R=H and -COCH₃). Seventeen acetates were spectrometrieally examined so that the data would provide a ready catalog of gas chromatography and mass spectrometric data for comparison with natural insect sex attractants. Exclusively cis and traps isomers were obtained by the catalytic and chemical reduction methods, respectively. Commercially available CH₃(CH₂)_mBr, CH₃(CH₂)_mC◎CH, HC◎C(CH₂)_nH and HO(CH₂)_n OH were used for the synthetic starting material. 1-Alkynes, CH₃(CH₂)_m C◎CH exceeding nine methylene groups did not condense with alkyl dihalides. The yield of coupling products was gradually decreased with increasing the molecular weight of diols. In the coupling reaction of BrCH₂CH₂ OTHP with acetylene gas, the tetrahydropyranyl ether of bromohydrin produced undesirable elimination product. In this experiment, it seems that p-toluenesulfonic acid is greatly favoured hydrolyzing agent over dilute sulfuric acid in the hydrolysis of the tetrahydropyranyl ether of long-chain alkynols.

This study shows the effect of 4% squid ink on the textural properties of squid during fermentation for 8 weeks at 10℃ or 32 days at 20℃ in 5% salt solution. Although the hardness and chewiness of the squid fermented with squid ink continuously decreased during fermentation, the degree of decrease was smaller than that of squid fermented without squid ink. We can conclude that squid ink inhibited the ripening of the low salt fermented squid.

In this paper, we introduce a comprehensive design methodology of Radial Basis Function Neural Networks (RBFNN) that is based on mechanism of clustering and optimization algorithm. We can divide some clusters based on similarity of input dataset by using clustering algorithm. As a result, the number of clusters is equal to the number of nodes in the hidden layer. Moreover, the centers of each cluster are used into the centers of each receptive field in the hidden layer. In this study, we have applied Fuzzy-C Means(FCM) and K-Means(KM) clustering algorithm, respectively and compared between them. The weight connections of model are expanded into the type of polynomial functions such as linear and quadratic. In this reason, the output of model consists of relation between input and output. In order to get the optimal structure and better performance, Particle Swarm Optimization(PSO) is used. We can obtain optimized parameters such as both the number of clusters and the polynomial order of weights connection through structural optimization as well as the widths of receptive fields through parametric optimization. To evaluate the performance of proposed model, NXT equipment offered by National Instrument(NI) is exploited. The situation awareness system-related intelligent model was built up by the experimental dataset of distance information measured between object and diverse sensor such as sound sensor, light sensor, and ultrasonic sensor of NXT equipment.

오성일,오기욱,김희진,박진석,김승현 대한신경과학회 2016 Journal of Clinical Neurology Vol.12 No.3

Background and PurposezzTe increasing recognition that defcits in social emotions occur in amyotrophic lateral sclerosis (ALS) is helping to explain the spectrum of neuropsychological dysfunctions, thus supporting the view of ALS as a multisystem disorder involving neuropsychological defcits as well as motor defcits. Te aim of this study was to characterize the emotion perception abilities of Korean patients with ALS based on the recognition of facial expressions. MethodszzTwenty-four patients with ALS and 24 age- and sex-matched healthy controls completed neuropsychological tests and facial emotion recognition tasks [ChaeLee Korean Facial Expressions of Emotions (ChaeLee-E)]. Te ChaeLee-E test includes facial expressions for seven emotions: happiness, sadness, anger, disgust, fear, surprise, and neutral. ResultszzTe ability to perceive facial emotions was signifcantly worse among ALS patients performed than among healthy controls [65.2±18.0% vs. 77.1±6.6% (mean±SD), p=0.009]. Eight of the 24 patients (33%) scored below the 5th percentile score of controls for recognizing facial emotions. ConclusionszzEmotion perception defcits occur in Korean ALS patients, particularly regarding facial expressions of emotion. Tese fndings expand the spectrum of cognitive and behavioral dysfunction associated with ALS into emotion processing dysfunction.

정서장애, ADHD 및 정서장애와 ADHD 공존질환을 지닌 아동의 주의력과 인지적 특성 비교

오성화 ( Sung Hwa Oh ),노경란 ( Kyung Ran Row ) 한국정서·행동장애아교육학회(구 한국정서학습장애아교육학회) 2015 정서ㆍ행동장애연구 Vol.31 No.1

본 연구는 정서장애, ADHD 및 정서장애와 ADHD 공존질환을 지닌 아동이 유사한 행동증상과 주의력 문제를 외현적으로 보이고 있어 감별 진단을 돕기 위해 실시하였다. 이를 위해 소아정신과 자문의 교수 및 임상심리전문가가 DSM-Ⅳ에 의거하여 진단한 초등학생들을 정서장애 집단(15명), ADHD 집단(13명), 정서장애와 ADHD 공존질환 집단(13명)으로 분류하였다. 주의력과 인지적 특성을 비교하고자 K-WISC-Ⅲ와 ADS의 점수를 일원변량분석으로 분석하였고, Sheffe 검사로 사후 검정을 수행하였다. 그 결과, K-WISC-Ⅲ의 동형찾기와 ADS에서 점수가 정서장애만 있는 집단은 정상 수준이지만 ADHD 집단과 정서장애 및 ADHD 공존질환집단은 주의력 문제가 있는 것으로 나타났다. 이는 진단 감별을 위해 K-WISC-Ⅲ의 동형찾기와 ADS가 유용함을 시사한다. 그러나 ADS에서도 정서장애 및 ADHD공존질환 집단과 ADHD 집단 간에는 차이가 유의미하지 않았다. 따라서 추가적인 연구를 통해 진단 감별 요인을 밝히는 것이 필요하다고 생각된다. The main aim of this study is to make Differential diagnosis of three groups ( a group of children with Emotional Disorders, one with ADHD and one with ADHD and Emotional Disorders) because children in these groups show similar behavioral symptoms and attention problems on the surface. For this study, professors of child psychiatric clinics and clinical psychologists classified elementary school students into three groups based on the results of DSM-Ⅳ: a group with Emotional Disorders( n=15), one with ADHD( n=13) and one with Group with ADHD and Emotional Disorders( n=13). To compare their attention level and cognitive characteristics, the scores of K-WISC-Ⅲ and ADS were analyzed by one-way analysis of variance and post hoc tests was done for Sheffe test. As a result, the group with Emotional Disorders were within normal range regarding the scores of K-WISC-Ⅲ symbol search and ADS, but the other two groups showed attention problems in the scores. K-WISC-Ⅲ symbol search and ADS are considered to be useful for Differential diagnosis. However, the difference between two groups, the group with ADHD and Emotional Disorders and one with ADHD, was not significant. For this matter, it seems to be necessary to perform additional studies to find more factors for discrimination.

추출농도에 따른 오미자 및 구기자를 첨가한 한방약술의 품질특성

오성천 한국응용과학기술학회 2019 한국응용과학기술학회지 Vol.36 No.1

In this study, the following is the result of measuring the quality characteristics of herbal wine and the active inhibition of Glutathione S-transferase in order to measure the release of physiological active substances according to the concentration of extracts. The pH level of herbal wine was 4.4, up from 3.9 before fermentation. These changes are attributed to fermentation and organic acids during alcoholic fermentation. The acidity of herbal wine was 0.55%, about six times higher than the pre-fermentation control of 0.09%. These results show that organic acids are used for flavor formation, ether, in combination with alcohol. The inhibitory activity of glutathione S-transferase were 5.1±0.31 in herbal wine 15%, 6.5±0.6 in herbal wine 20%, 7.6±0.6 in herbal wine 25%, 8.4±0.2 in herbal wine 30% and 9.7±0.7 in herbal wine 35%. As the extract concentration was increased the inhibitory activity of glutathione S-transferase were significantly increased (<0.05). 본 연구에서는 한약재의 활용도를 높이기 위한 연구로 추출물 농도에 따른 생리활성물질의 용출량을 측정하기 위해 한방약술의 품질 특성과 Glutathione S-transferase의 활성 저해능을 측정한 결과는 다음과 같다. 한방약술의 pH결과는 4.4로 발효 전의 대조구 3.9보다 증가하였다. 이러한 변화는 알코올 발효과정 중 발효부산물 및 유기산 때문으로 사료된다. 한방약술의 산도는 0.55%로 발효 전의 대조구 0.09%보다 약 6배 증가하였다. 이런 결과는 유기산이 알코올 등과 결합하여 ester와 같은 향미 형성 등에 이용되는 것을 알 수 있다. 한방약술 15%의 glutathione S-transferase의  활성 저해능 5.1±0.3, 한방약술 20%는 저해능 6.5±0.5, 한방약술 25%는 7.6±0.6, 한방약술 30%는 8.4±0.2, 최대 농도인 35%에서의 저해능은 9.7±0.7로 나타내었다. 추출 농도별로 glutathione S-transferase의 활성 저 해능은  통계학적으로  유의한 차이가 있음을 보였다 (p<0.05).
