The market of Internet-based fashion/coordination shopping malls have been growing rapidly year by year. In accordance with this growth, Internet fashion shopping malls are also making a lot of efforts to increase their revenue by displaying new fashion products on a high spot or by having professional models wear them to make them more attractive to the customers. If online shopping malls have the functionality of automatically calculating the matching degree of lower and upper clothes, it could play a role of off-line shop assistants and provide a more convenient way of purchasing fashion products for customers. In this paper, we present a learning system adopting the content-based filtering method for online shopping malls, which automatically calculates the matching degree of lower and upper clothes and recommends the most well-matched pair.

Effect of Fe and Mn contents on the tensile properties has been studied in Al-9wt%Si-0.3wt%Mg alloy. As Fe content of Al-9wt%Si-0.3wt%Mg-0.5wt%Mn alloy increased from 0.15wt% to 0.45wt%, tensile strength of as-cast alloy decreased from 192 MPa to 174 MPa, and elongation of the alloy also decreased from 4.8% to 4.2%. Decrease of these properties can be explained as the formation of plate shape, ${\beta}-Al_5FeSi$ phase with high Fe/Mn ratio of the alloy. However when Mn content of Al-9wt%Si-0.3wt%Mg-0.45wt%Fe alloy increased from 0.3wt% to 0.5wt%, tensile strength of T6 aged alloy increased from 265 MPa to 275 MPa, and elongation of the alloy increased from 2.3% to 3.6%. These improvements attribute to chinese script, ${\alpha}-Al_{15}(Mn,Fe)_3Si_2$ phase shape-modified from ${\beta}-Al_5FeSi$ phase with low Fe/Mn ratio of the alloy.

In this study, in order to explore the contextual elements of book use that were overlooked in the existing book recommender system research, for 15 avid readers with various book search backgrounds, the contents generated in 6 book search situations were collected through the think-aloud protocol. By using content analysis from the collected book use contents, not only the internal and external appeal factors affecting book use, based on the 'appeal factor', the theoretical concept of the readers' advisory service, but also information sources and search methods regarding book use were identified and categorized. The results of this study can be used to extract and reflect meaningful attribute data in the future book recommender system design process.

Microwave dielectric properties of $(1-x)CaWO_4-xYNbO_4$ ceramics have been investigated as a function of $YNbO_4$ content($0.05{\leq}x{\leq}0.4$). A single phase with tetragonal scheelite structure was obtained up to x=0.10 and then the secondary phase with fergusonite structure was increased. With the increase of $YNbO_4$ content, apparent densities of the specimens were decreased. This results were due to the lower theoretical density of $YNbO_4(5.581g/cm^3)$ than that of $CaWO_4(6.117g/cm^3)$. Dielectric constant(K) and quality factor(Qf) were decreased with $YNbO_4$ content which could be attribute to the decrease of density and the increase of secondary phase. Temperature coefficient of resonant frequency (TCF) of the specimens with the $YNbO_4$ content was depended on dielectric mixing rule.

The purpose of this study was to investigate the contributions and limitations of an independent internet newspaper dedicated to disability affairs. The materials analysed in this study were articles on personal assistance service conflicts between users and assistants by Ablenews. This study used inductive content analysis, responsibility frame analysis, and disability paradigm analysis. First, in general Ablenews appeared to report personal assistance service conflicts as they were. Second, the results showed that Ablenews tended to attribute the causes and solutions of the conflicts to the users and assistants. Third, nearly half of content units of Ablenews articles conveyed the perspective of rehabilitation paradigm though personal assisstanc services are closely related to independent living model. Based on the results this study suggested that Ablenews needs to improve specialty in reports on disability affairs using editorial staff, professional reporters, guests reporters with specialties.

This study analyzes the fuel conditions and environmental effects of converting heating in rural villages that rely on fossil fuels into wood fuel. In particular, we tried to derive the most important considerations when using wooden chips as fuel in aging agricultural villages where various variables such as weather, facility characteristics, fuel quality, and maintenance capabilities work. Above all, an experiment was conducted by comparing it with oak trees to determine whether Italian poplar, a representative attribute water created to supply fuel wood in Korea, is suitable for heating fuel. Through experiments, 1) Even though the supply of poplar wood chips during 10 hours of operation was 60.74 kg less than that of hardwood chips, the production of hot water was 140 kWh higher. 2) The higher the exhaust gas temperature, the proportional (increase) oxygen concentration and inversely (decrease) PM and CO emissions. 3) Poplar has twice as much ash content as hardwood and three times more fine dust has been detected, but it meets all the standards for wood quality at the Korea Forest Science Institute. 4) Under the condition that there is a difference in water content (7.7%), hardwood cost 1.13 times more wood chips per 1 MWh than poplar, and even if the water content is corrected equally, hardwood cost 1.05 times more per 1 MWh than poplar. 5) In conclusion, it was proved that the fuel possibility, economic possibility, and environmental possibility of poplar wood chips are sufficient.

In this paper,we present an dffcient way to describe the commplex meaning embedded in video data for the cintent-based retrival in a video database.Intead of viewing the data stored in a file as continuous bit stream,we associate the desired interval in the stream with a set of atteibute and value pairs which describe its meaning.Since the meaning of video data can be cimplex and can change dyamically. It is necessary to com-bine the fixed schema of attributes used in the traditional database systrm with a description method through a set of attribute and value pairs that can be defined dynamically.As the cintent of viedo data can be expressed differently according to the view point of a user,it is important ot maintain the meaning of the attribute and value pairs cinsistently for different users.This paper proposes the dffctive way to manage the set of attri-bute and value pairs.In addition,it also describes a way to define a new video presentation by separating a video stream phsycally or by sharing the portion of a bit stream,and the new method can minimize the required storage space.

The purpose of this study is to obtain basic information and suggestions needed to measure reading attitude by obtaining the tacit knowledge. For this, a semi-structured interviews were carried out with teacher librarians and elementary school teachers and elementary students in five elementary schools. The results were as follows: Students and Teachers divided standard and attribute for assessing reading attitudes as student's ability, personality and behavioral aspects towards reading. Students were aware of the necessity of reading and accepted a pleasant feeling of reading. However, group of students with low reading skill recognized reading as an academic purpose as compared to other student groups and expressed a negative feeling on reading. Peers, teachers and family members were recognized as figures who make an impact on reading by students and further considered the subject, content and physical attribute of book as important factors. Teachers recognized reading attitude as a concept on attitude about book and book reading. Further they mentioned reading environment, interests, habits, books, and experience as factors affect reading attitude.

A document type definition(DTD) which defines tags for a document is a XML document grammar that defines syntactic structure of a document. An XML document keeps the rules and must be parsed to check validation. To parse XML document, the deterministic parsing method of programming language is irrelevant because it does not satisfy the definition of deterministic content model in element declaration. In this paper, we consider editing of a valid XML document in syntax-directed editing environment, and we suggest the internal storage representations of syntax in DTD and theirs algorithms. The consequence is that a syntactic structure of textual DTD is transformed into graph and table structures. The table structure of DTD is interpreted the context free grammar which has attribute values and is used in syntax-directed editor for XML. We called this the XML abstract grammar and showed generated results and examples.

Sprout ginseng paste were prepared with pine nut, dry oyster and dry shrimp to examine the antioxidant properties(total polyphenols, total flavonoids, and electron donating ability) and sensory test(attribute difference and acceptance). Sprout ginseng paste were measured based on color value, pH, viscosity, total bacteria cell numbers for 0 and 20 days at $4^{\circ}C$. The higher total polyphenol and total flavonoid content of sprout ginseng paste added with pine nuts, dry oyster, and dry shrimp were higher antioxidant capacity. DPPH radical scavenging activity was increased from 52.2% (SGP0) to 79.5.0 % with SGP5. The attribute test results reveal that the color intensity, bitter taste, and oily taste were decreased in SGP3 to SGP6. Taste, flavor, and coarseness did not show significant difference in SGP0 to SGP6. Thickness and After taste were increased in SGP4 to SGP6. The preference test results reveal that the appearance, flavor, and texture level did not show significant difference in SGP0 to SGP6. Taste and overall preference were increased in SGP4 to SGP6. L value, pH, decrease while a value and b value show no change in sprout ginseng paste with pine nut, dry oyster and dry shrimp. Total cell number was not detected during storage.
