The goal of this thesis is to make a comparative study about the variant form of the Chinese character in the five sorts of old maps drawing outside of the main gates of old map including DeDongYei-jido. The main task of this thesis can be classified under three heads - (1) introducing the literature of comparative study in the five sorts of old maps including DeDongYei-jido (2) classification of variant form in the five sorts of old maps (3) characteristic of variant form in the five sorts of old maps. In this thesis, aspect of variant form is classified under six head - (1) variation of the whole shape of the character (2) taking place the variation in both sides of Chinese character (3) taking place the variation in part (4) taking place variation in the strokes of the Chinese character (5) misusing different characters (6) changing different characters. This thesis explains some characteristic of variant form - (1) simplification of the shape of characters (2) using the Hou-qi-zi(後起字, Chinese character which is actually the same but made the next) (3) replacing the overlapped both sides of Chinese character with omit mark (4) a wrongly written character (5) discovering the variant form such as variant form of 廣, 广 variant form of 廛, variant form of 院 which was not recorded in Chinese literature. From now on, there should be some collections of variant form of Korean style and study. we are going to have to standardize aspect of variation and rule of variant form in old maps until we have to make some ways to recognize the block letter.

This study aims to contribute to development of sanitary pad meeting customers' requirements by examining types, sorts, sizes and specifications of cloth sanitary pads currently sold in the market, and the results are as follows. First, with respect to materials of inside cloth of cloth sanitary pads, in most cases, 100% cotton knit was used as materials of the inside cloth and the pads were finished with knit cotton(including organic cotton) and woven cotton bias. Second, for the structures of the cloth sanitary pads, the Jacquard knits in the shape of beehive or waffle are mostly used. Third, the sizes of cloth sanitary pads were classified with 7 sorts were discovered that can be divided into liner, small-size, medium-size, large-size, overnight, extra overnight, accounting for the most percentage among cloth sanitary pads. Fourth, 11 sorts among cloth sanitary pads whose front and back shapes are the same were discovered, accounting for the most percentage. Fifth, cloth sanitary pads can be largely classified into a wing type, all-in-one type and insertion type, which includes subsidiary absorption layer. 9 sorts were wing types and all-in-one types, accounting for the most and percentage. Compared with the scope of the market for women's articles, there is no relevant study, so this study is expected to provide basic materials for women's articles and contribute to development of environment-friendly products as an alternative to a disposable sanitary pad which not only causes environment pollution but also has bad effects on women's health.

The purpose of this study were 1) to find out impression dimensions of the dress wearer with various motifs 2) to evaluate the impression effects of motifs in Korean traditional dress for women. The research method was a quasi-experimental with the between subjects design. The experimental materials developed for the study were a set of stimuli and response scale. The stimuli were consisted of 12 drawings with full factorial design of 3 independent variables : motif sorts (2:flower animal) motif types(2: realistic stylized) motif arrangements(3: all over the traditional to modern) The stimuli consisted of color photographs and color of clothing and motifs was controlled the blue. The response scales were consisted of 30 bi-polar adjectives. The subjects were 333 undergraduate college students of Taejon. The data was analyzed by factor analysis MANOVA and Duncan's multiple range test. Results were as follows: 1. The wearer's impression were consisted of the 3 different dimensions : attractiveness · dignity dimension. Interaction effect among motif sorts motif types and motif arrangements was significant on the same dimension. Interaction effect between motif sorts and motif arrangements was significant on the visibility dimension. 3. The motif arrangements were a significant variable on the attractiveness·dignity and the evaluation dimension. The traditional arrangement and the modern arrangement showed more faborable impression and the all over arrangement showed less favorable impression on the attractiveness·dignity dimension. The all over arrangement showed positive impression on the evaluation dimension and the traditional arrangement and the modern arrangement showed negative impression on the same dimension. There were no significant difference between flower sort and animal sort and also no significant difference between realistic type and stylized type in their impression effects.

In order to Investigate the adsorption characteristics of organochlorine pesticides chlorothaloul and dicofol with soul colors and re참tons far souls of an orange orchard, the souls were sampled at 3 re삼tons, respectively. among black volcanic, dark brown volcanic, and broom nonvolcanlc sorts. Every so6 has a higher clay proportion (49-75%) In sol tcuture and the organic carbon content and cation ekchange capacity with soil decreased in the following sequence: Black volcanic > Dark brown volcanic > Brown nonvolcanic sorts. Especially those In black volcauc trolls were much higher than others. The retention time, quantitative detection limit, and extractian , efficiencies of chlorothalonil and dicofol were 2.82min, 1.5ng/mL, 93.6% and 3.64min, 4.5ng/mL. 94 2%, repectlvely. The Freundlich constant, Kd, was higher in dicofol compared to chlorothalonil and In the black volcanic souls that have higher organic carbon content and cation Bkchange capacity. The Freundlich constant, 1 In, was In the range of 0.76-0.89 In the black volcanic sorts that have a higher organic matter(16.4-19.8%), whereas It was In the range of 1.02-1.13 In the brown nonvolcanic souls that have a lower organic matter(2.4-3.4%), and so It was considered that 1 In was dependent on the organic matter.

We study the structure of central elements in relation with polynomial rings and introduce quasi-commutative as a generalization of commutative rings. The Jacobson radical of the polynomial ring over a quasi-commutative ring is shown to coincide with the set of all nilpotent polynomials; and locally finite quasi-commutative rings are shown to be commutative. We also provide several sorts of examples by showing the relations between quasi-commutative rings and other ring properties which have roles in ring theory. We examine next various sorts of ring extensions of quasi-commutative rings.

We investigated the effects of parametric synthesis conditions of catalysts such as sintering temperature, sorts of supports and compositions of catalysts on alignment and length-control of carbon nanotubes (CNTs) using catalyst powders. To obtain aligned CNTs, several parameters were changed such as amount of citric acid, calcination temperature of catalysts, and the sorts of supports using the combustion method as well as to prepare catalyst. CNTs with different lengths were synthesized as portions of molybdenum and iron using a chemical vapor deposition reactor. In this work, the mechanisms of alignment of CNTs and of the length-control of CNTs are discussed.

The aim in this note is to describe some classes of rings in relation to factorization by prime radical, upper nilradical, and Jacobson radical. We introduce the concepts of tpr ring, tunr ring, and tjr ring in the process, respectively. Their ring theoretical structures are investigated in relation to various sorts of factor rings and extensions. We also study the structure of noncommutative tpr (tunr, tjr) rings of minimal order, which can be a base of constructing examples of various ring structures. Various sorts of structures of known examples are studied in relation with the topics of this note.
