  • 수집된 주름버섯류의 233점의 phylogenic relationship을 분류하고 자실체형태를 조사하였다. 리보좀 DNA의 ITS 부분의 염기서열을 분석을 통해 38점이 다르게 동정되었다. 수집된 주름버섯의 계통수에서는 양송이와 여름 양송이가 group A 내에서 주름버섯은 group B에서 가까운 유연관계를 보였다. 또한 수집된 국가별 및 양송이내 갓색에 따른 유연관계가 있는 지 알아보았으나, 그 차이는 없었다. 수집된 주름버섯류의 자실체 특성을 조사하기 위해 1차, 2차 두 번 재배를 하였다. 이 결과로 주름버섯류 수집균주의 재배의 유무를 알 수 있었고, 버섯 종류와 시기에 따른 수확량 및 자실체의 특성을 비교를 통해 주름버섯이 2차 재배시 수확량 및 경도에서 우수한 특성을 보이며, 양송이 중에는 비백색양송이가 단단하다는 것을 알 수 있었다. 또한, 여름양송이의 초발이 소요일수와 갈색양송이의 갓 색이 외부환경에 영향을 받는 다는 것을 보여주었다.

  • 본 연구는 춘란 품종간의 유전적 유연관계를 밝혀 교배육종에 기초자료로 활용하기 위하여 수행하였다. 춘란 수집종 20 품종에 대하여 형태적 특징 19가지를 조사하여 유연관계를 분석하였다. 20개 수집품종들은 크게 2군으로 분류되었으며, I군에는 7개의 수집 품종이 속하였고, II군에는 13개의 수집 품종이 속하였다. I군에는 잎에 무늬가 없는 품종들로 구성되어졌으며, II군에는 무늬가 있는 품종들로 구성되어졌다. 10 종의 10 mer primer를 이용하여 RAPD 분석을 통해 유전적 유연관계를 분석하였다. RAPD결과 총 89개의 band를 얻었으며 그 중 monomorphic band는 3개, polymorphic band 86개였다. 수집품종간의 전체적인 유사도는 0.521~0.862의 범위로 나타났다. 유전적 유연관계 또한 2군으로 분류되었으며, X군에는 16개의 수집품종이 속하였고, Y군에는 4개의 수집품종이 속하였다. 외형적특징을 이용한 분류와 RAPD를 이용하여 유전적 유연관계를 분류한 결과는 정확히 일치하지 않았지만 유전적 유연관계를 통하여 분류된 Y군의 품종들은 모두 외형적 특징을 이용한 분류의 II군에 포함되었다. 본 연구의 RAPD에 의한 유연관계분석에서 유사도가 낮은 품종간에 교배조합을 구성한다면 보다 높은 효율의 결과를 얻을 것으로 기대된다.

  • In order to design a good ready-made cloth, it is important to consider not only body size but also morphological factor. However, most dissatisfaction of customer is focusing on the size of ready-made cloth which is graded with elements of body size. Various researches on body type have been doing but the study on part of body type is insufficient compared to the study on whole body type. The objective of this paper is to provide relationship of shoulder angle between value in pattern and real measured value after analysis and comparison with these two values.

  • This paper is intended as a study on how an utterance is divided into rhythmic units in Standard Korean with respect to its syntactic structure. With respect to the data in this study I used 150 sentences which contained similar number of words and various syntactic structures. Those sentences were read by 7 speakers of Seoul dialect in a conversation style. Each sentence was read twice in a normal speed and twice in a fast speed. As a total, 4200 sentences were recorded. Then listening to them, the author marked the sentences with two kinds of boundaries i.e. strong and weak. To explore the relationship between rhythmic units and syntactic structure I devised a framework of grammatical symbols. Each symbol is designed to have both syntactic and morphological information at the same time. So I assigned those grammatical symbols to the sentences. Having sentences marked with grammatical symbols on the one hand, and with the rhythmic boundaries on the other hand, 1 could show the relationship between rhythmic units and syntactic structure; which syntactic structures are likely to be pronounced as one rhythmic unit, and which are on the rhythmic boundaries.

  • Purpose: This study was to investigate the relationship between the palpebral fissure and the exophthalmos in an elder women population in Korea subjects with normal eye status. Methods. From November 2014 to July 2015, The author analyzed the morphological values in 81 Korean elder women population. The clinical test was performed using the Hertel exophthalometer and verner califer. Analysis of data were described using the spss 20 and Pearson's test. Results. The mean age of the 81 subjects (162 eyes) was (73.938+/8.585)mm. The mean value of palpebral fissure was (5.673+/-2.065)mm in width and (24.179+/-4.409)mm in height. The mean value of exophthalmos was (5.537+/-2.151)mm. There were a significant relationship(P>0.01) in the mean size between the width and height in palpebral fissure. Also, there were a significant relationship(P>0.01) in the mean size between the palpebral fissure width and exophthalmos. Also, there were a significant relationship(P>0.01) in the mean size between the palpebral height width and exophthalmos. However, there were not significant relationship(P>0.01) in the mean size between the palpebral fissure width and exophthalmos in right eye. On the other hand, The relationship between right eye and left eye of the palpebral fissure and exophthalmos was similar results. Conclusions. In this study, these results suggested that the palpebral fissure and exophthalmos was a significant relationship in the mean value of morphologic characters in Korean elder women population.

  • We, for the first time, reported molecular sequences of large subunit ribosomal DNA Dl-D3 region of A. hiranoi, A. leei and A. satoanum hitherto unreported. In addition, this study presented the full-length sequences of A. affine, A. fraterculus, A. catenella and A. tamarense occurring in Korean coastal waters. In total, 17 Alexandrium morphospecies were subjected to the phylogenetic analysis using the Maximum-likelihood (ML) method. The alignment result of sequences of A. hiranoi and A. pseudogonyaulax showed that there were only two substitutions without length heterogeneity implying their genetic affiliation. In ML tree, A. leei formed a deeply diverging branch probably because of the accelerated evolutionary rate, and its phylogenetic position was so ambiguous to resolve the phylogenetic relationship to the residual taxa. An A. satoanum culture showing morphological variation in the sulcal plate formed an independent divergent branch with consistent sister relationship to A. hiranoi/A. pseudogonyaulax clade supported by the high posterior probability (PP) value. Blast search in GenBank showed the sequence data of A. affine, A. fraterculus, A. catenella and A. tamarense corresponded to their morphological species designation. In ML tree, Alexandrium species were commonly split into four main clades. The inter-clade relationships were not clear and usually supported by the week PP values. In general, the sulcal plate of Alexandrium species seemed to reflect the true phylogeny at the main clade level, and the connection between the 1 and the apical pore complex seemed to reflect the phylogeny at the subclade level.

  • Objective: In this study, we aimed to examine the relationship between chin deviation and the positional and morphological features of the mandible and to determine the factors that contributed to chin deviation in individuals with a unilateral cleft lip and palate (UCLP). Methods: Cone-beam computed tomography (CBCT) images of 28 adults with UCLP were analyzed in this study. Segmented three-dimensional temporomandibular fossa and mandible images were reconstructed, and angular, linear, and volumetric parameters were measured. Results: For all 28 individuals, the chin was found to deviate to the cleft side by 1.59 mm. Moreover, among these 28 individuals, only 7 showed distinct (more than 4 mm) chin deviation, which was toward the cleft side. Compared to the non-cleft side, the mandibular body length, frontal ramal inclination, and vertical position of the condyle were lower and inclination of the temporomandibular fossa was steeper on the cleft side. Furthermore, the differences in inclination of the temporomandibular fossa, mandibular body length, ramus length, and condylar volume ratio (non-deviated/deviated) were positively correlated with chin deviation. Conclusions: UCLP individuals show mild chin deviation to the cleft side. Statistical differences were noted in the parameters that represented positional and morphological asymmetries of the mandible and temporomandibular fossa; however, these differences were too small to indicate clinical significance.

  • 본 연구는 붓꽃속 식물의 형태적 특성 조사와 RAPD분석을 통해 유전적 다양성과 근연성을 밝히고 유전자 도입을 위한 기초적인 자료를 얻기 위하여 실시하였다. RAPD를 이용하여 국내에서 수집한 자생붓꽃종의 DNA다형성을 조사한 결과 40개의 primer중 8개의 유용한primer가 선발되었고 이들 primer는 108개의 밴드를 나타내었다. 이들 중 다형성 밴드는 107 개였다. Jaccard (1-S$_{J}$ )법에 의한 비유사도 계수는 0.095∼0.699로 나타났고, dendrogram에서 나타난 유전적 근연성은 크게 세 개의 군으로 분류되었다. I군은 연미붓꽃, II군은 타래붓꽃, 제비붓꽃, 노랑꽃창포, 노랑무늬붓꽃이 속해 있었으며, III군은 금붓꽃, 각시붓꽃, 붓꽃, 꽃창포가 속해 있었다.
