This paper describes the characteristics of high speed grinding and the influence of wheel surface speed V and a grindability of the grinding materials. The various fine ceramics pieces was ground by metal and vitrified bonded diamond wheel. The surface roughness of fine ceramics(Zirconia($ZrO_2$), Silicon Carbide(SiC), Silicon Nitride($Si_3N_4$), Alumina($Al_2O_3$)) decreases from $0.05{\mu}m(R_{max})$ to $0.025{\mu}m(R_{max})$ when the wheel speed at grinding point increases the wheel speed. Relation between the temperature at grinding point and surface roughness was linear. Abrasive jet machining(AJM), a specialized from of shot blasting, is considered one of the most helpful micro machining methods for hard and brittle materials such as glasses and ceramics by constant pressure grinding.

The Linked Open Data(LOD) cloud is quickly becoming one of the largest collections of interlinked datasets and the de facto standard for publishing, sharing and connecting pieces of data on the Web. Data publishers from diverse domains publish their data using Resource Description Framework(RDF) data model and provide SPARQL endpoints to enable querying their data, which enables creating a global, distributed and interconnected dataspace on the LOD cloud. Although it is possible to extract structured data as query results by using SPARQL, users have very poor in analysis and visualization of RDF data from SPARQL query results. Therefore, to tackle this issue, based on Formal Concept Analysis, we propose a novel approach for analyzing and visualizing useful information from the LOD cloud. The RDF data analysis and visualization technique proposed in this paper can be utilized in the field of semantic web data mining by extracting and analyzing the information and knowledge inherent in LOD and supporting classification and visualization.

The purpose of this study is to find out more rational way to manage clothing. The study is based on a survey of daily clothing practices. 112 female college students who are majoring clothing, textiles, and/or home economics have responded to the questionnaires. With the samples, frequency, factor analysis, discriminant analysis, ANOVA, and Scheffe test are pursued respectively. Main results of the survey analysis could be summarized as follows : 1. Female college students are found to possess 70 units on average. They possess more of casual clothes such as polo·T shirts, casual pants, and casual shirts (from the highest frequency in order). They possess less of formal clothes such as one-piece and two-pieces (from the lowest frequency in oder). 2. It is found that 12 per cent of the possessed clothings are not used at all during the year. The unused rate is higher for the formal suits while it is lower for the casuals. 3. The possession pattern is affected by clothintg life style factors : brand and economic factors for the casuals ; fashion and individuality factors for the formals. 4. The possession pattern is also affected by the purchasing behavior factors, purchasing price among others.

The conservation treatment process of sword is below. First, examples written inlay with tortoise-shell design is a big sword with round head excavated Namwon Wolsanri in Korea, big swordsexcavated the Sungchong Ⅱ tomb of Naranghyun, the Moksun Ⅰ tomb of Ejihyun, the Jangjonsan Ⅰ tomb of Dogunhyung in Japan. The period of inlay artifacts are known to about 6c. Therefore, sword is infer to beexcavated to 6c.Second, inlay artifacts excavated the domestic at present were known to 19-pieces. But sword is a big sword inlaid with silver to projecting hilt. This artifact is very important to scholarship data because of be first excavated to the domestic

A shop floor control system (SFCS) is the central part of a CIM system used to control the activities of several pieces of manufacturing equipment (e.g., NC machines, robots, conveyors, AGVs, AS/RS). The SFCS receives orders and related process plans, and then performs selecting a specific process routing, allocating resources, scheduling the workpieces, downloading the processing instructions (e.g., RS-274 instructions for NC machines, VAL II programs for robot), monitoring the progress of activities, detecting and recovering from errors, and preparing reports on the status of the manufacturing system. Simulation has been utilized in discovering control policies used for resolving shop floor be control problems such as resource contentions, part dispatching, deadlock. The simulation model must be designed to respond to real-time data coming from a shop floor. However, to rapidly build a realtime simulation model of SFCS cannot be easily accomplished. This talk is to address an automatic program generator of discrete event simulation model for shop floor control from process plans and resource models. The program generator is capable of constructing complete discrete simulation models for multi-product and multi-stage flexible manufacturing systems.

The two-dimensional guillotine cutting problem is to maximize sum of piece profits that cut from one stock rectangle and widely applied in the industry. The branch-and-bound method for this problem uses complementarily several upper bounds(the Gilmore and Gomoryp[8]'s two-dimensional knapsack function and the Hifi and Zissimopoulos[10]'s method using one-dimensional knapsack problem, etc) to reduce the number of searched nodes. These upper bounds has a shortcoming that does not consider the bound and layout of pieces simultaneously. In this paper, we propose an efficient upper bound which can complement the shortcoming of existing upper bounds. The proposed upper bound needs less memory spaces and computing time. Computational results show that the proposed upper bound significantly contribute to reduce the computational amount of time and number of searched nodes in tree.

This study covers the literature of theoretical backgrounds of royal ceremonial hair styles during Chosun Dynasty and demonstrates reproduction works of those hair styles reinterpreted in modern methods. As for the Chosun royal hair styles for ceremonies, there are Daesoo, Gudoomi, and Euyoumi for a royal queen, royal concubines, and royal lady attendants of Nae Myung Boo, department of general affairs of the royal court. These hair styles represents well that Chosun Dynasty kept its own class symbols through hair styles, which is valuable cultural resources of Korean traditional beauties. This study compares the new reproduction works of Daesoo, Gudoomi, and Euyoumi with existing literature pieces and related photos for clear understanding of these traditional hair styles. This study aims to activate the relevant researches into Korean traditonal hair styles, their reproduction methods and applicable usages in Modern Korea as well as useful data for them.

Recently, as it has greatly increased the demand on the serviceability of subway, cable tunnel, the stability of the tunnel structures has been attracting the concern of engineers and researchers. The purpose of this study is to idently the various characteristics of lining concrete in subway structures. The nondestructive technique such as the surface hardness method and the extend of carbonation by phenolphthalein indicator and chemical analysis due to XRD are considered. Also, the concrete core was cut in three pieces per tunnel for the exact evaluation of strength.

When current flows through a thick conductor such, most of the current flows along outside of the conductor, which is called skin effect. This paper represents a method calculating such a current distribution in the conductor region. The conductor region is divided into some pieces and each piece has its own unknown variable, i.e. current density. The governing equation which expresses Maxwell's equation is combined with the circuit equation with voltage source. The combined equation is solved to obtain current distribution in the conductor. This algorithm is applied to EMC(Electromagnetic Casting) to calculate current density with voltage source.
