R을 이용한 부분실시법

박정섭 청주대학교 2016 産業科學硏究 Vol.33 No.2

In this paper, we dicussed the fractional experiment design using R. If the number of factors in factorial experiment increase the numbers of treatment can sharply increased, the confounding method as a way to reduce the number of treatment. However, even in confounding method, if a large number of factors may increase the experiment If we want to obtain the comparison between the level of a factor, fractional experiment can be perfomed.

통계패캐지들의 처리속도 비교

박정섭 청주대학교 2014 産業科學硏究 Vol.31 No.2

The operation time of well known three kinds statistical packages-SAS, MINITAB, R- were examined, and the results obtained were as follows : SAS is the fastest among three packages. But SAS is very expensive. Minitab is slowest, and under some condition Minitab can not operate becase of overflow. Compared to the SAS, R has similar speed with SAS. Many of the researchers have participated in the development of R program, and R is free. For this reason the R is a good alternative

고구마 경엽을 식품소재로 활용하기 위해 신황미, 하얀미, 스이오우를 수확시기(60, 90, 120일) 및 마디별(1~5, 6~10, 11~15마디)로 채취, 동결건조한 후 분쇄하여 L값과 총 폴리페놀 함량, DPPH 라디칼 소거 활성을 측정하였다. 그 결과, 신황미는 하얀미, 스이오우에 비해 높은 폴리페놀 함량과 DPPH 라디칼 소거 활성을 나타냈으며, 이는 재배기간이 길수록 정상의 순에 가까울수록 높았다. 90일 동안 재배한 후 1~10마디의 경엽을 채취, 2단계 열풍건조법으로 제조한 신황미, 하얀미, 스이오우 경엽 분말의 총 아미노산 함량은 각각 2,469, 3,384, 2,531 mg/100 g, 총 무기물 함량은 각 7.23, 6.54, 7.11 g/100 g, 총당은 각 11.6, 12.8, 18.2 g/100 g, 비타민 E 함량은 3.04, 3.18, 1.52 mg/100 g이었다. 또한 총 폴리페놀 함량은 각각 5.03, 3.90, 4.02 mg/g, ${\beta}$-카로티노이드는 75.6, 71.6, 63.1 mg/g이었고, DPPH 라디칼 소거 활성($EC_{50}$)은 각각 0.29, 0.36, 0.33 mg, ABTS 라디칼 소거 활성($EC_{50}$)은 0.12, 0.15, 0.11 mg으로 시금치보다 2배 이상 강한 활성을 나타내었다. The foliage of sweet potato [Impomoea batatas (L.) Lam] is an excellent source of food material due to the functional components of polyphenol and carotenoid. In this study, the lightness (L-value), polyphenol contents, and DPPH radical scavenging activity of the foliage of Shinwhangmi, Hayanmi and Suioh cultivars harvested after different cultivation periods (60, 90 and 120 days after planting) and according to tip locations (1st~5th, 6th~10th, 11th~15th tips) were investigated. As a result, Shinwhangmi showed a lower lightness value (60 days after planting and 1st~5th tips). The longer the cultivation periods and the closer the tips, the higher the contents of polyphenol and DPPH radical scavenging activity were in lyophilized foliage of Shinwhangmi, Hayanmi and Suioh. In the 1st~10th tip of Shinwhangmi, Hayanmi and Suioh cultivated for 90 days and dried by 2 step hot-air (1st: $70^{\circ}C$ for 8 hr, 2nd: $80^{\circ}C$ for 4 hr), the polyphenol and ${\beta}$-carotenoid contents were 5.0, 3.9 and 4.0 mg/g and 75.6, 71.6 and 63.1 mg/g, respectively. The DPPH radical scavenging activities and ABTS radical scavenging activities ($EC_{50}$) were 0.29, 0.36 and 0.33 mg and 0.12, 0.15 and 0.11 mg, respectively. These antioxidative activities were over two times stronger than spinach.

R을 이용한 다차원척도 분석

박정섭 청주대학교 2017 産業科學硏究 Vol.35 No.1

Multidimensional scaling is a technique for geometrically shaping the n objects on a p-dimensional space based on similarity (or mutuality) data between two pairs of objects, by relative coordinate of the n objects on a lower dimension than p dimension. In this study, we intended to plot the Korean people 's preference level of the 19th presidential election, using the open package R. The result of this research showed that the group of the average people can be classified into 2 groups, which are north area centered at Incheon, centrol area including Chungbuk and Kangwon.

Objectives : This study was designed to evaluate the anti-diabetes and vasoelasticity effects of Mori Folium and Aurantii Fructus in streptozotocin-induced type II diabetes mellitus model. Methods : The anti-diabetic effect of Mori Folium and Aurantii Fructus on rats induced with diabetes by streptozotocin was investigated through analyses of changes in body weight, blood glucose, urine volume of rats, viability of human umbilical vein endothelial cells(HUVECs), and elasticity of descending thoracic aorta in rats. The subjects in this study were divided into four groups(n=15): a normal group without any treatment (Con), a normal group with Mori Folium and Aurantii Fructus treatment(Con+P), a diabetes group induced by streptozotocin(STZ), and a Mori Folium and Aurantii Fructus treatment group under diabetes induced by streptozotocin(STZ+P). Rats were administered streptozotocin to induce diabetes. Results : The study showed that Mori Folium and Aurantii Fructus significantly reduced highly increased blood glucose levels(p<0.01) and prevented the diabetic rats from weight loss(p<0.01) and polyurea(p<0.05), Mori Folium and Aurantii Fructus also recovered decreased viability of HUVECs(p<0.01) and damaged elasticity of aorta induced by the streptozotocin (p<0.01). Conclusions: It was concluded from the results that Mori Folium and Aurantii Fructus have a distinct anti-diabetes effect and they also prevent damage of blood vessel induced by diabetes. resulting in prevention of cardiovascular diseases ascribed to diabetes.

Recently, a lot of research results for finding suitable models using graph in the expression of log-linear model for contingency tables which have multinomial distribution have been published In this research, using the result of the Cluster Analysis based on the Fourier series guggested by Andrew, we made standardization of the curve in order to be the same between Pearson's chi-square statistic and each curve.

프랑스어 분열문의 유형과 한국어 번역

박정섭 한국프랑스학회 2022 한국프랑스학논집 Vol.117 No.-

L’objectif du présent travail est de décrire les constructions clivées (CC) en français, et de proposer leurs équivalentes en coréen. La clivée prototypique est composée des trois parties suivantes: c’est – l’élément clivé la proposition – relative (e.g. c’est - le champagne – que j’aime). L’élément clivé y représente à la fois le focus, i.e. l’information nouvelle, et la valeur de la variable x présentée dans la relative (x tel que j’aime x). Mais, aujourd’hui, on a tendance à adopter une définition étendue des CC, qui nous permet d’en avoir une nouvelle typologie avec 8 constructions non prototypiques en plus de la prototypique. En examinant les propriétés sémantico-pragmatiques de ces 9 types de CC, nous constatons que pour décrire l’interprétation de ceux-ci, il faut tenir compte essentiellement de leur structure informationnelle, et vérifier si l’interprétation exhaustive y est ou non imposée et si l’élément clivé est ou non mis en contraste. Ensuite, prenant en compte ces facteurs interprétatifs, nous proposons les types de constructions en coréen qui correspondraient le mieux, du point de vue sémantico- pragmatique, à chacun des 9 types de CC en français. Ces derniers deviennent le plus souvent, en traduction coréenne, une phrase canonique (avec ou sans focus, avec ou sans topique) ou une pseudo-clivée (‘… 것은 …이다’ ou ‘… 것이 …이다’). 본 연구는 프랑스어 분열문들의 특성을 기술하고 그것들이 한국어로 번역되는 방식을 제안하는 것을 목적으로 한다. 전형적인 분열문은 ‘c’est - 분열요소-의사관계절’이라는 3부분으로 구성된다(예: c’est - le champagne - que j’aime). 분열요소는 문장의 초점, 즉 신정보에 해당하며 의사관계절에서 제시된 변항의 값을 명시한다. 그런데 오늘날 분열문에 대한 넓은 정의가 받아들여져서, 전형적인 분열문 외에 8개의 비전형적 유형을 모두 분열문으로 간주하는 경향이 있다. 본고에서는 9개의 분열문 유형에 대해 의미-화용론적 특성을 검토하면서 그것들의 해석이 주로 정보구조, 문장의총망라적 해석 여부, 분열요소의 대조성 등에 의해 결정된다는 것을 확인하였다. 그 다음에 그러한 중요한 해석적 요인들을 고려하여 9개 프랑스어분열문 유형 각각에 가장 잘 상응하는 한국어 구문의 유형들을 제시하였다. 프랑스어 분열문들은 한국어로 번역될 때 대개의 경우 초점이나 화제를 포함하거나 포함하지 않는 기본문이나 ‘ 것은 이다’ 또는 ‘ 것이이다’ 형태의 의사분열문으로 된다.
