The sword with a ring pommel, which was excavated from the first stone chamber of the ancient tombs of Jeongchon Village in Naju, is a sword with a pentagon undecorated ring pommel consisting of a mother sword and two child swords. The sword with an undecorated ring pommel of Jeongchon comprises a ring pommel, a hilt, a knife, and a knife end decoration. This sword was coated with lacquer. The ring pommel is an iron frame covered with silver plate; however the silver tarnished into a light purple due to silver chloride corrosion, and iron corrosion originated from the inside is visible on the surface. Silver chloride corrosion is produced when silver objects are exposed to water, dissolved salts, and dissolved chloride ions when in a buried state. It changes objects into powder, making it difficult to preserve original shapes. The other silver artifacts found in the Jeongchon ancient tombs show similar signs of corrosion. The results of X-ray irradiation and a CT analysis showed that the sword had a ring at the end of the handle, a T-shaped hilt, and was probably connected to the handle end of a knife. If the shape of the mother sword can be inferred from the child swords, the mother sword had a ring pommel, decorations of the handle, covered with silver plate, and a gold ring and a silver line wound around the handle. It is assumed that the ring pommel was connected to the knife by welding because no holes were observed. The end decoration of the knife was made by using an iron plate formed into a shape, half covered by silk, and the other half decorated with silver plate and a gold ring. The sword with an undecorated ring pommel excavated from the ancient tombs of Jeongchon Village comprises the metals of gold, silver, and iron, and includes features of Baekje, Silla, and Gaya, which highlights the influence of surrounding historic sites and various cultures.

Jeollabuk-do is bounded by the sea, and Mahan Baekje culture have been established around a wide plain. Also, in southeastern, it was closed by Gaya kingdom where iron culture was prosperous at that time, a variety of the handles of swords with round pommel is excavated at present. The handles of swords with round pommel is the best amount of excavated objects among the swords with round pommel and producted object for the time. It supposes them to become the foundation of making the decorated swords with round pommel. But, the handles of swords with round pommel that don't have a pattern in handle is indifferent to study because the production method is simple in spite of that the value of archaeological data is sufficient. Therefore, in this study, it examined changed production techniques with the change of times concerning the handles of swords with round pommel of Mahan Baekje Gaya period(before 6C) excavated from Jeollabukdo through using X-rays in order to clarify a variety of production techniques of the handles of swords with round pommel correctly in accordance with a period of production and excavated place. As a result, identified production techniques using X-rays of the handles of swords with round pommel excavated around remains of Mahan Baekje Gaya period shows that production progress improved in order of all-in-one shape, hammer welding shape of the handle of round pommel, and two in body formation in accordance with age. Especially, in two in body shape, it products the handle of round pommel separately, after that it welds the handle of swords and then links the sword blade like a riveting or bottleneck and so on. Despite of improved hammer welding technique, the reason why it didn't utilize is it regards as inlay or gilt will be damaged. And it is judged by using riveting or bottleneck. Also, it appears to techniques of metal craft such as decoration of the handle, decoration of point of sword, inlay, and silver-plating in the period of appearing two in body shape. As clarifying correctly, it provides fundamental database of scientific research about a study of production techniques of handle of swords with round pommel.

Chlorinated aliphatic hydrocarbons (CAHs) such as tetrachloroethylene (PCE), 1,1,1-trichloroethane (1,1,1-TCA) are the contaminants most frequently found in soil and groundwater. They have a potential to be toxic to and persistent in environment. This study is focused on selection of zero-valent metal and ores for the removal of high concentration PCE or 1,1,1-TCA and mixture of two compound. For the screening of suitable metals, we measured dechlorination rate, removal capacities and economics by using batch reactor test. This results suggest that removal rate and dechlorination of high quality iron and zinc are higher than slag and nature ores like zinc and manganese. Among nature ores, zinc ores(64% purity) have highest removal capacities. And in economics zinc ores is 10 times better than high quality metal tested. We conclude zinc ore is most suitable metal for the removal of PCE or 1,1,1-TCA.

Amid growing social interest in child abuse, and announced the seriousness of child abuse crimes and aroused public interest in related issues. Based on true stories and characters, both films created unique narratives about child abuse cases, but drew on the traditional representation and discursive construction of child abuse news articles. By setting the stepmother as the perpetrator and the father as the neglecter, the gender role of women as primary caregiver was reconfirmed and the stereotypical image of the 'evil stepmother' in popular narratives was exploited. The cinematic reenactment of the evil stepmother not only highlighted the normative family discourse, but also reinforced the maternal myth by emphasizing the binary opposition between the evil stepmother and the lost birth mother.

In this paper, we implemented a content-based image retrieval system that user can choose a wanted query region of object and retrieve similar object from image database. Query image is induced to wavelet transformation after divided into hue components and gray components that hue features is extracted through color autocorrelogram and dispersion in hue components. Texture feature is extracted through autocorrelogram and GLCM in gray components also. Using features of two components, retrieval is processed to compare each similarity with database image. In here, weight value is applied to each similarity value. We make up for each defect by deriving features from two components beside one that elevations of recall and precision are verified in experiment results. Moreover, retrieval efficiency is improved by weight value. And various features of database images are indexed automatically in feature library that make possible to rapid image retrieval.

The imagery of Ophelia appeared in Russian literature in the middle of the $19^{th}$ century. In contrast with Hamlet, whose name had been always in the center of the most intense debates through centuries, Ophelia had been understood relatively monotonously and simply associated with the images of a chaste maiden, a tragic heroine and a devoted lover. Only after the feminist literary criticism shed new light on the complicated inner world of the young girl, the imagery of Ophelia radically changed, and now it is not difficult to encounter various Ophelias on the contemporary stages and culture. In this paper we study the remarkable changes of the imagery of Ophelia in Russian modernism poetry, analysing A. Blok, A, Akhmatova, M. Tsvetaeva's Ophelia poems. Ophelia in Russian modernism, on the one hand, succeeding to the traditional view on Ophelia in $19^{th}$ century, assumes interesting new aspects, sometimes preempting feminist point of view.

Purposes of this study, summoning thoughts and activities of Toynbee Hall of the UK and Hull House of the US held in between the end of 19C and the early 20C, are two folded: first, it is to examine the momentum and aims for which 'social' work was progressively established at that time; second, it is to look for implications for today's social work practice through understanding their characteristic activities and the context in which 'social' work was devised as an alternative in the two nations. The study method mainly relies on literature review, but further goes on to analyze the spirit of the age when settlement house was constructed as a welfare space and activities, leadership demonstrated in there, and to draw meanings for today, in terms of three dimensions: aim and location, professionality and education, and social action. Some of useful findings are: first, the COS and settlement house need to be considered in a continuum of socially responsive remedies against poverty and social work practice was developed in the process of 'suggestion-performance-critique-alternative suggestion-emergence of social work', rather than contrasting the two as opposite roots of social work practice. Second, settlement house was a socially constructed welfare space that contained intersectional dynamics of class, gender, personal vs. social, private vs. public, surrounding poverty issue. Third, besides differences between the two settlements, both purported for public goods and well-being and tried to realize the 'social' in that society. Lastly, this study explored historical meanings of settlement house as the welfare space with critical questions and discussed implications for social work practice today.

This study is concerned with "fiction" as a new form of writing over the limits of the post-modernist theater/arts. Fiction is not something illusory that demands the audience's empathy but something that unveils form's disinterest in content. Thus, in this paper, I examine a fiction as the opposition of any representational norm and words' old mimesis. Rebutting the crisis of post-modern art and the end of images, philosopher Jacque $Ranci{\grave{e}}re$ mentions the possibility of appropriating similarity in an imitative way by twisting Platonic mimesis. The image of this similarity wanders alongside the loss of signification, unmasking the form's indifference to content. These wandering words represent their own truth "in a way fossils or grooved stones encapsulate histories" as hieroglyphics. This "fiction" as an alternative of post-modernist plays is not any confrontation of reality but the "movement of thinking" that allows the human spirit to play in a way of shaping "some substantiality." In this sense, I examines works by two French writers, $Jo{\ddot{e}}l$ Pommerat (1963~) and Jean-Claude Grumberg (1939~ ) who have carried out their writing practices of appropriating similarity that dissolves any simple "immediate reflection" for non-intermediate relations between the producing and the produced. Their writing is a cross of literary creation and "le politique" as a new aesthetic practice of writing and reveals the movement of thinking, departing from the preexisting concept of fiction.
