  • This study aims to analyze difficulties that pre-service elementary teachers experience in investigating the life cycle of a common cabbage butterfly in person. As difficulties they face during the process of this research, they pointed out collecting eggs, observing molting, creating environments for a breeding cage, feeding, building a breeding cage, and making butterfly specimens. Out of all the environmental difficulties related to their school fields, they pointed out a difficulty of time management most of all, followed by placing a breeding cage in the classroom and the lack of microscopes for observation. In regard to difficulties related to their evaluations on students' activities, they found it difficult to evaluate students' activity with the life cycle of an insect in the aspect of knowledge and even to set evaluation criteria. Besides, many of them responded that it would be appropriate to evaluate a research on the life cycle of an insect through a portfolio or an observation journal. In regard to difficulties in terms of teachers' knowledge, they found it difficult to understand insect molting, metamorphoses, complete metamorphoses, incomplete metamorphoses, the structure of an insect body, and how to distinguish a female insect from a male one. In regard to the application of class models, they knew it is important for students to have various experiences through direct observation, so the experience-based learning model was proper for the process of observing the life cycle of a common cabbage butterfly. However, they found it difficult for students to observe each stage of the life cycle in person.

  • The purpose of this study is to analyse the inclinations and expressions in contemporary architecture. Specially, we call this tendency and architectural movements as architectural metamorphosis. Metamorphosis in architecture present the core of the change of Forms and spirits in a change of outward shape and terrestrial identity. As in Ovid's extended dramatic poem of change and transformation, Metamorphoses, all Souls are deathless, and migrates from one form to another. Like these stories in Metamorphoses, Ovid tells the soul never dies, but leaps one form to anther, and can take any shape. So the architectural form, transformation and deformation in contemporary architecture means architectural sensations and cognitions can even approach the soul of form and shape under the transformation. The expressions and design strategies of metamorphosis in comtemporary architecture reveal continuous and sequential formations of space, linear structure with force and vector, rhythmical wavement and folding surface, lively wiggly flows of volumns and objects, and so on. Such qualities came from the periodical needs; separation of structure and surface, poly-surfacial movement, poly-sensual expression and experience, dematerialization and the dematerialized space, formless of non-formal architecture, digital architecture. Architecture of Metamorphosis is the ways and the needs of our period to overcome the static limits prohibits the liberal thoughts, to find the ways toward the opportunities and diversities and to unlock the imaginaire of the contemporary architecture.

  • Egypt has gone through a major metamorphosis following the Egyptian Revolution that began on 25 January 2011. The aim of this article is to analyze the influence of the aforementioned metamorphoses on the Egyptian Arbitration Law and Practice and to shed light on the recent developments of the latter. Whilst positive legislative amendments have been recently achieved with regards to enforcement of arbitral awards, it is crystal clear that the January 2011 Revolution has negatively impacted the jurisprudence of the Administrative Court of the Conseil d'Etat which has annulled several arbitration clauses enshrined in contracts related to privatization. However, save for disputes arising from administrative contracts, Egypt has been and shall remain a friendly seat of Arbitration as it possesses an arbitration-friendly legislation, its Ordinary Judicial Courts are familiarized with international arbitration practice and it has a prominent and famous arbitration Centre.

  • The fundamental mechanism of a dispersed two-phase flow was investigated. Experiments were carried out to understand how the particles behaves under the influence of the particle size, shape, metamorphoses (bubble) and buoyancy of a single particle which is ascending from the standstill water. Two CCD cameras were employed for image processing of the behavior of the particles and the surrounding flow, which was interpreted with the technique of correlation PIV (Particle Image Velocimetry) and PTV (Particle Tracking Veloci- metry), respectively The experimental results showed that the large density difference bet- ween a particle and water caused high relative velocity and induced zigzag motion of the particle. Furthermore, the turbulence intensity of a bubble was about twice the case of the spherical solid particle of similar diameter.

  • Pierre breaks the rules of convention and acquires the 'potential not to do.' To transform the traditional hero into the new potential subject, Pierre moves from his hometown, Saddle Meadows, New York City to the dungeon of the city prison and creates three different relationships that symbolize what ideology and principles repress his mind and behavior and how he handles them. Firstly, in Saddle Meadows, Pierre has a narcissistic relationship with his mother, Mary, who teaches him the principles of American manhood and forces him to be docile: he has to obey Mary's order that a man should be a gentleman. Therefore, since he does not know his potential, he does not create his own work and is involved in plagiarism. Secondly, in New York City, Pierre creates an associated relationship with Isabel, his half-sister, who represents an ambiguous and mysterious character and has the 'potential not to do' that leads Pierre to destroys the beliefs of American manhood and performs the potential to do. Consequently, Pierre puts himself in an extreme situation and is absolutely liberated from the influence of his dead father, who unconsciously controls Pierre's behavior and thoughts. Thus, he makes a dissociated relationship with his father. In the dungeon, he physically dies, but symbolically metamorphoses into Isabel, so that he blurs the differences between Isabel and himself. Furthermore, he never stays in his own way: in this on-going process, Pierre cannot determine which is good or bad, legitimate or illegitimate and life or death.

  • In Korea, a resident registration card has various personal information such as a present address, a resident registration number, a face picture and a fingerprint. A plastic-type resident card currently used is easy to forge or alter and tricks of forgery grow to be high-degree as time goes on. So, whether a resident card is forged or not is difficult to judge by only an examination with the naked eye. This paper proposed an automatic recognition method of a resident card which recognizes a resident registration number by using a refined ART2-based RBF network newly proposed and authenticates a face picture by a template image matching method. The proposed method, first, extracts areas including a resident registration number and the date of issue from a resident card image by applying Sobel masking, median filtering and horizontal smearing operations to the image in turn. To improve the extraction of individual codes from extracted areas, the original image is binarized by using a high-frequency passing filter and CDM masking is applied to the binaried image fur making image information of individual codes better. Lastly, individual codes, which are targets of recognition, are extracted by applying 4-directional contour tracking algorithm to extracted areas in the binarized image. And this paper proposed a refined ART2-based RBF network to recognize individual codes, which applies ART2 as the loaming structure of the middle layer and dynamicaly adjusts a teaming rate in the teaming of the middle and the output layers by using a fuzzy control method to improve the performance of teaming. Also, for the precise judgement of forgey of a resident card, the proposed method supports a face authentication by using a face template database and a template image matching method. For performance evaluation of the proposed method, this paper maked metamorphoses of an original image of resident card such as a forgey of face picture, an addition of noise, variations of contrast variations of intensity and image blurring, and applied these images with original images to experiments. The results of experiment showed that the proposed method is excellent in the recognition of individual codes and the face authentication fur the automatic recognition of a resident card.

  • Scuticociliatosis has badly settled one of most damaging diseases during the seedling production process of olive flounder. Paralichthys olivaceus in Korea. We isolated a new type of Scuticociliate from flounder. The parasite metamorphoses to ciliate and cyst phases with each other by environmental changes and survive for a relatively long span. The ciliate was measured average 41.8 ${\mu}m$ in length and 21.0 ${\mu}m$ in width, and cyst was 17.0 ${\mu}m$ and 13.5 ${\mu}m$, respectively. Nutritional condition was determined as a major parameter of metamorphosing between ciliate and cyst stages. The ciliate transforms to a cyst stage because of food shortage, and the cyst returns to a ciliate stage with a favorite environmental condition and shows active growth and reproduction. The ciliate multiplied at the maximal density of $2.9 {\times} 10^5 {m\ell}^{-1}$cells in vitro cultivation at $15 ^{\circ}C$temperature using MS BHI medium and bacterial food sources. The ciliate could be proliferated at a 2.5 to $30 ^ \circ}C$ temperature range, pH 6 to 9, and 1 to 55 ppt salinity. Particularly, it survived over one week at $0 ^{\circ}C$temperature showing a high resistance against unfavorable environmental conditions. And the cyst survived for 320 days in the condition of $5 ^{\circ}C$with no feeding, but its survival period was markedly shortened in higher temperature conditions. The chemotherapeutants (formalin and hydrogen peroxide) were clarified as effective chemicals against the ciliate during in vitro trials, but the effect of therapeutants differed in proportion, depending upon the density and the bathing time of chemical compounds.

'The Same Scenery' and 'a Different Landscape' Included in "Real-Scenery Landscape Painting", an Essay to Determine Meaning - Centering around Paintings of Chong Seok Jeong in the 18th-19th Centuries - (실경산수화에 담긴 '같은 경관' 그러나 '다른 풍경', 그 의미 찾기 - 18.19C 총석정 그림을 중심으로 -)

  • This research focused on the process in which 'the same scenery' is recognized and represented as 'a different landscape' to determine the symbols and meaning of the scenery and landscape included in real-scenery landscape paintings of the 18th-19th centuries. As a result of analyzing the visual points, the content and expressions of 25 real-scenery landscape paintings of Chong Seok Jeong(叢石亭), it can be seen that the transmission of a kind of semiotic landscape on the basis of a specific symbol was accomplished naturally through imitation and representation for the purpose of the expression of Chong Seok Jeong-like idealized scenery. This shows that the unique images of Chong Seok Jeong have long been passed down after taking root as a unique benchmark The meaningful symbol of 'a strange Saseonbong(四仙峰)', which is broken by the spray after rising high, and 'a pine forest' have both been transmitted as being in the manner of Chong Seok Jeong. This has been equipped with the stereo-type scene by being a collective symbolization as the psycho-scenes in memory element of Chong Seok Jeong. Through the pictures of both Gyeomjae(謙齋) and Danweon(檀園), the process by which a specific painter's pictures become acculturated is highly interesting. The scenery expressed in these pictures was clearly that of a landscape of which its particularly emotions and remembrances were repainted through the experience of several places and original sketches. This can be explained as the concept in which the image from 'a specific scenery' gained through actual experience, that is, a personal feeling, has been expressed. The picture that was expressed as a different figure even at the same visual point for the same scenery is the result that was redefined through the scenery subject's recognition. Also, the modification of the scenery object can be colorful through meditation and Sachu(邪推: guessing with wicked doubt). The scenery recognized newly through adoption, omission and emphasis, it is 'the specific scenery' in the heart and is a figure having been more similar to 'a landscape' if the objective life reproduction before being acculturated is a figure similar to the scenery. So, the concept looks like being very persuasive that 'the nature with objectivity captured sensuously' simply is the scenery, and that 'the subjective phenomenon having acquired the cultural nature by being introspected in the method of aesthetic nostalgia is a landscape'.
