  • Gray leaf spot (GLS) is a serious fungal disease caused by Pyricularia oryzae Cavara, recently reported on the important turf and forage species, perennial ryegrass (Lolium perenneL.). This fungus also causes rice blast, which is usually controlled by host resistance, but durability of resistance is a problem. Few instances of GLS resistance have been reported in perennial ryegrass. However, two major QTL for GLS resistance have been detected on linkage groups 3 and 6 in an Italian x perennial ryegrass mapping population. To confirm that those QTL are still detectable in the next generation and can function in a different genetic background, a resistant segregant from this population has been crossed with an unrelated susceptible perennial clone, to form a new mapping population segregating for GLS resistance. QTL analysis has been performed in the new population, using two different ryegrass field isolates and RAPD, RFLP, and SSR marker-based linkage maps for each parent. Results indicate the previously identified QTL on linkage group 3 is still significant in the new population, with LOD and percent of phenotypic variance explained ranging from 2.0 to 3.5 and 5% to 10%, respectively. Also two QTL were detected in the susceptible parent, with similar LOD and phenotypic variance explained. Although the linkage group 6 QTL was not detected, the major QTL on linkage group 3 appears to beconfirmed. These results will add to our understanding of the genetic architecture of GLS resistance in ryegrass, which will facilitate its use in perennial ryegrass breeding programs.

  • The present study explored a relationship between mathematical understandings of teachers and ways in which their knowledge transferred in designing lessons for hypothetical students from Gess-Newsome (1999)'s transformative perspective of pedagogical content knowledge. To this end, we conducted clinical interviews with four secondary mathematics teachers of their solving and teaching of equation writing. After analyzing the teacher participants' attention to Key Developmental Understandings (Simon, 2007) in solving equation writing, we sought to understand the relationship between their mathematical knowledge of the problems and mathematical knowledge in teaching the problems to hypothetical students. Two of the four teachers who attended the key developmental understandings solved the problems more successfully than those who did not. The other two teachers had trouble representing and explaining the problems, which involved reasoning with improper fractions or reciprocal relationships between quantities. The key developmental understandings of all four teachers were reflected in their pedagogical actions for teaching the equation writing problems. The findings contribute to teacher education by providing empirical data on the relationship between teachers' mathematical knowledge and their knowledge for teaching particular mathematics.

  • Currently, there are many simple searches for local culture and tourism, but systematic information retrieval using ontology technology is weak. The keyword-based search, which is an existing search method, derives a search result that is different from a user's wanted intention. On the other hand, semantic search using ontology constructs shows the information related to the search term by creating a relation between words and words. Therefore, when tourists search for cultural and tourist attractions in the area, they provide information that includes meaning relevance in the search results. If the ontology provides information on the culture, sightseeing area, transportation, Can be more easily grasped. In this paper, we propose an ontology-based retrieval system based on culture and tourist sites utilizing public institutions database by using mobile application by extending search system which relied only on existing internal database to provide accurate and reliable information to users. This efficient structure of the ontology makes it possible to provide information suitable for the user quickly and accurately.

  • The purpose of this study is to determine how the Korean diphthong /jo/ shows phonetic variation in various linguistic environments. The pronunciation of /jo/ is discussed, focusing on the relationship between phonetic variation and the distribution range of vowels. The location in a word (monosyllable, word-initial, word-medial, word-final) and word class (content word, function word) were analyzed using the speech of 10 female speakers of the Seoul Corpus. As a result of determining the frequency of appearance of /jo/ in each environment, the pronunciation type and word class were affected by the location in a word. Frequent phonetic reduction was observed in the function word /jo/ in the acoustic analysis. The word class did not change the average phonetic values of /jo/, but changed the distribution of individual tokens. These results indicate that the linguistic environment affects the phonetic distribution of vowels.

Psychological Meaning of Creation Myths: Focused on Darkness/Massa Confusa, Separation of World Parent and Creation of Land/Island (무의식의 창조성 관점으로 고찰한 창조신화: 흑암/혼돈, 천지개벽/분리, 섬/육지 창조 중심)

  • The purpose of this paper is to present the psychological meaning of the creation myths by utilizing related myths, analysand's dreams, active imagination, and artwork to reveal the creative function of the unconscious. The creation myth is the phenomenon of projection when a new order is demanded in the chaotic phase of personal and human history. Depending on the attitude of the ego, it can be a sign of a reconstruction/alteration of consciousness or an invasion. Related literature such as Jung, von Franz, Neumann, Harding, and Edinger, domestic papers, and case reports are introduced to identify the background for this research. The psychological meaning of 'darkness' in creation myths is regarded as unconscious that is too dark to see. The Eskimo creation myth and an analysand's dreams of being blind and wandering in darkness are discussed in relation to nigredo in Alchemy. The psychological meaning of 'massa confusa' regards Uroboros, pleroma, early childhood experience, and a psychological womb in which everything is contained in one. With related myths and unconscious materials, a discussion is followed on how this realm can be a precursor of creation but also be trapped in an abyss. The psychological meaning of 'separation of world parent' is related to splitting one into two when unconscious contexts were touched before it became consciousness. Related myths, 'the world created between heaven and earth,' 'celestial being descending to the earth,' and 'the legend of relocation of a mountain,' as well as clinical material, are examined. Then this paper discusses the clinical implications of the separation of heaven and earth occurring on its own, that the creator's emotional aspects, such as loneliness and anxiety, are involved, and that delayed separation leads to the death of creatura and sudden separation leads to the death of the chaos. Then, the meaning of 'separation of world parent' is discussed in relation with separatio, the alchemical process of acquiring light/consciousness from darkness/unconsciousness. The psychological meaning of the creation of 'land/island' refers to the emergence of consciousness, the contents of the unconscious material into the realm of the ego. Related myths, such as the 'body of the monster/dragon becoming land' and analysand's dreams, are introduced, referring to the embodiment of Mercurius. This is followed by discussing related myths in creating the land to coagulatio in alchemy and utilizing creative work such as active imagination, art, music, and dance that can coagulate or concretize unconscious material in clinical approaches. Finally, myths of resurfaced land after the Flood or the complete destruction of the world in relation to the reconstruction of ego are discussed with related clinical material to show the importance of the analyst/therapist/supervisor's mental stability and capacity.

  • Usually social control and acceptance of science and technology is thought to be a separate or even confronting thing. But this paper aims to go beyond this simple and dichotomous thinking. Rather, this paper argues that social control and acceptance of science and technology can be combined altogether organically. In other words, this paper argues that social control of a particular science and technology has functional effects to the acceptance of that science and technology. Social control of a particular science and technology is a signal that something is going wrong; it reallocates attention and enhances social awareness; it evaluates ongoing activity; and it alters this activity in various ways to secure a sustainable future. In order to prove this functional hypothesis, this paper tries a case study of biotechnology from a perspective of sociology of science and technology. Especially social controversies around genetically modified organisms(GMOs) and embryo cloning in Korea are analysed deeply. As a conclusion, this paper proposes some policy implications of this study.

대순사상의 인문정신과 인류평안의 이념

  • 대순사상은 인간의 행위와 정신적 틀, 즉 몸과 마음을 닦고 세상을 다스리며 백성을 평안하게 하는 도리를 설파하고 있다. 우주 공간의 질서와 깊은 연관을 맺는 이러한 도리는 인간 자신의 인지(認知)와 심신 수양의 내용을 포함하며, 사람이 사회와 우주자연과의 관계를 어떻게 처리해 나갈 것인지에 관한 문제도 다루고 있다. 따라서 대순사상을 인문이라는 관점에 입각하여 분석해 볼 필요가 있다. 이탈리아에서 시작된 서양의 인문주의와 비교해 볼 때, 중국 전통의 인문정신은 인류 개체의 창조력과 그 성과를 인정하고, 인격적 수양과 개선을 주장하며, 사회의 조화를 강조하는 한편, 인류가 반드시 천지인의 조화로운 관계 속에서 개체와 전체의 생존을 파악해야 함을 강조한다. 이러한 인문정신은 『전경』에서도 찾아볼 수 있다. 그 하나가 모악산과 단주(丹朱)에 대한 서술인데, 모악산은 산 즉 '간'(艮)괘이며 단주는 적색에 상응하니 곧 '리'(離)괘가 된다. 이 두 괘가 서로 조합하면 '비(比)'괘가 되며, 『주역』의 비괘와 연관하여 서로 간의 모순을 없애고, '바둑'을 두는 기법을 거울삼아 심성을 다스리며, 인격을 완성하고, 인신이 조화를 이루도록 하며, 사회를 안정시킬 것을 말한다. 대순 신앙의 최종 목표는 지상천국을 건설하는 것인데, 이런 목표를 실현하기 위해서는 인격수양을 그 출발점으로 삼아야 한다. 인격수양의 목표는 바른 도인이 되기 위한 것이며, 이를 위해서는 수도 공부를 해야만 한다. 수도는 춘추시기 노자 이래로 유구한 문화적 전통을 지닌 것이지만, 대순진리회는 한국사회 역사의 경향과 현실의 필요에 부응하여 수도 이론을 새롭게 수립하였다. 이를 살펴보면, 대순진리회는 수도자가 '성(誠), 경(敬), 신(信)'에 힘쓰는 품격 함양을 매우 중시한다. 또 도인들이 가정의 화목에 힘써야 하며, 솔선수범하는 도인으로서 사회의 모범이 되어야 한다고 말한다. 이렇게 볼 때, 대순진리회는 '인도'(人道)를 함양함을 강조하고 있으며, 이것은 전통적인 유가에서 말하는 '수신, 제가' (修身, 齊家)의 정신과 그 의미가 맞닿아 있다. 또한 중국 도교의 '선도(仙道)를 이루고자 하면 먼저 인도(人道)를 행하라'는 사상적 취지와도 일치한다. 대순진리회에서 수도의 최종 목표는 도통이다. 도통은 수도자가 매우 높은 경지에 이르게 되었을 때 가지는 특수한 능력과 정신의 경지이다. '도통'에 대한 기록은 『장자·제물론』, 『문자』의 「부언편>(符言篇) 등에서 찾아볼 수 있는데, 대순진리회가 말하는 도통은 중국의 도가 전통에 보이는 도통과도 연관되지만 강한 인륜수양(人倫修養)적 특색을 지니고 있다는 점에서 차이가 있다. 이것은 대순진리회가 가지는 중요한 인문적 함의라 하겠다. 대순진리회는 수도 공부로써 광제창생·보국안민·지상천국건설의 사회적 이상을 실현하고자 한다. 조화로운 사회적 관계를 수립하기 위한 토대는 대순진리회의 종지 첫 번째인 음양합덕이다. 음양합덕은 대순진리의 인문 취지의 이론적 기초를 형성하는 사상이다. 음양합덕의 철학적 사고는 종지 두 번째인 신인조화(神人調化)의 이상으로 이어진다. 신인조화는 『상서·순전』(尙書·舜典)의 신인이화(神人以和)에서 그 사상적 연원을 찾아 볼 수 있다. 다만 신인이화가 율려 조화의 '결과'를 표현한 것이라면, 신인조화에서 중시하는 것은 '과정'이며 인간과 신의 상호작용이라는 점에 그 특징이 있다. 신인조화를 이루기 위해서는 공부를 해야 하며, 그 배후에는 인본(人本)의 사상이 깃들어 있다. 그것은 종지 세 번째인 '해원상생'의 내용에서 더욱 명확하게 드러난다. 신인조화가 인간과 신의 관계를 조화롭게 하는 것을 말한다면, 해원상생은 인간과 인간의 관계를 조화롭게 하는 것을 말한다. 또 다른 한편으로는 긴 역사의 과정 속에서 맺힌 원을 풀어 우주의 기운을 잘 통할 수 있게 하고 인간 사회의 정상적인 교류를 이루도록 한다. 이러한 내용은 사회적인 인문적 관심과 배려를 다분히 포함하고 있는 것이다. 대순진리회의 종지 네 번째인 도통진경은 수도의 가장 높은 경지를 말하는데, 이러한 이념은 노장 일파의 도가 학자들이 말한 순박한 본성으로 회귀하자는 정신에서 그 원류를 찾을 수 있을 것이다. 또한 이는 한진(漢晉)시대 이래 중국 도교가 추구했던 '진경' 의 의미와도 합치된다. 그러나 시대와 환경이 다름으로 인해, 대순진리회의 '진경'은 사회생활의 의미까지 내포한다. 비록 대순진리회의 경전이 인본(人本)을 명확히 밝히고 있지는 않으나, 대순진리회의 요의(要義) 중 하나인 인존사상은 대순진리회의 인문정신을 말해주는 것이다. 인존사상의 직접적인 기능은 평안(平安)으로서 삶을 이롭게 하는 것이다. 대순진리회는 우주대원의 진리를 '도'라 하였는데 이러한 '도'는 중국의 도가에서 말하는 '도'와 동일하며, 여기에는 '안(安)'의 의미가 포함되어 있다. 대순진리회의 신조 중 '안심', '안신'은 마음을 정(靜)하게 하고, 몸을 편하게 하는 것으로 볼 수 있지만, 심신의 공포와 두려움을 떨쳐내어 안전과 보호를 얻는다는 의미도 있으므로 결국 평안이 전제가 된다. 이렇듯 대순진리회에서는 '평안에 대한 희구'를 근본으로 하여 신앙인들이 열심히 수도에 정진하고 있다. 대순진리회가 인류 평안을 기본으로 하는 종교라는 점에서, 반드시 세인들의 환영을 받을 것임을 믿어 의심치 않는다.

  • The purpose of this study is to analyze the characteristics and problems of the content of flower design education videos on YouTube and to search for improvement direction. The subjects of analysis were 129 pieces of videos uploaded in the last one year including 'craftman floral design' as a search term. The result shows that contents covered were practical lectures, theory lectures, test related tips, job and character introduction, test work, educational guidance and publicity. The production format could be divided into studio lecture, classroom lecture, video feature, interview, Vlog, and television program. The hub-type programming strategy that periodically uploads the videos satisfying the target audiences' interests is mostly applied. The type of lecture covered 'practical skill test' got a good response from the users. Overall, content diversity, interaction between creators and users, and harmonious programming strategies are lacking. In order to improve this, it is necessary for emotional and expressive creators to pioneer differentiated fields and practice based on actual field. The introduction of interactive elements such as games and quizzes and the application of new media technologies such as VR and AR are worth trying. Three strategic types of 'hero', 'hub', and 'how to' should be applied complementary. As the demand for education content related to flower design is expected to expand in the future, it is required to develop content that can be used in various platforms, foster professional creators, and develop associated business models.

  • The purpose of this paper is to design the curriculum by considering the experimental design and analysis for enhancing an engineer's creative problem-solving ability. This ability is one of the important objectives in modern engineering education. To achieve this purpose, first, it is suggested that the experimental design and analysis, a specific area of engineering education, is highly relevant to the creative problem-solving ability, one of the basic engineering competencies and of the final goals in engineering education. And also, the curriculum already introduced the experimental design and analysis in departments of mechanical engineering of universities are surveyed and reviewed. 59 papers are also analyzed to know how engineers applicate the knowledge of the experimental design and analysis to their activities. Finally, the module of engineering education curriculum introduced the experimental design and analysis to enhance effectively the engineer's creative problem-solving ability is suggested.
