A cost minimization model for designing AS/RS (Automated Storage/Retrieval Systtems) has been developed under the S/R (Storage/Retrieval) machine throughput rate and total storage capacity requirements. The objective function includes S/R machine cost storage rack cost, and interface conveyor cost. Since the model is a nonlinear integer programming problem which is very hard to solve with large problem size, the model is simplified using previous research results to be solved exactly and a simultion procedure is combined to verify that throughput rate requirements are satisfied.

For over 100 years, the tall building has largely advanced in technological innovation; however very little has been done in the terms of understanding the changing needs of the occupant needs and experience. The vast changes occurring due to technology and mobility demand reconsidering the tall building today and for the future. This paper will briefly survey the past eras of tall building design and will propose considerations and solutions for the future.

The objective of this paper is to investigate the variation of orifice diameter in a straight pipe which can give equal-sampling rate. This can be utilized for designing orifice in air-sampling smoke detector. The elements which should be considered for designing orifices was presented and the calculation procedure was also given in this paper. The effects of pipe length, the number of orifices, fan pressure was decribed.

This paper considers the problem of designing static output feedback controllers for nonlinear systems represented by Takagi-Sugeno (T-S) fuzzy models. Based on linear matrix inequality technique, a new method is developed for designing fuzzy stabilizing controllers via static output feedback. Furthermore, the result is also extended to $H_{\infty}$ control. Examples are given to illustrate the effectiveness of the proposed methods.

In order to understand the current state of production and pattern design of circular knitted jackets, this study selected 11 female clothing brands based from the "2012/2013 Korea Fashion Brand Yearbook" and interviewed the staff in charge of patterns at the companies. Polyester and polyurethane were found to be synthesized and used for the outshell of circular knitted jackets, alternatively natural fabric cotton or wool were synthesized with rayon. As for the structure of circular knitted materials, Ponte Di Roma knitting structure (a modified form of a double knit) was most often used. Surveying the use pattern and the parts for padding cloth, six responded that they used elastic padding cloth. As for circular knitted jackets with inner lining, elastic padding cloth was attached to all parts (front, back, side panel, and collar - except for sleeves) of the basic bodice pattern. Eight responded that they did not use a basic pattern when designing a pattern, which exceeds the majority. All respondents answered yes to the question on if there is any difference in designing a pattern for a woven jacket and a circular knitted jacket. It was found that they designed a pattern that considered shrinkage and elongation, which are the features of circular knitted fabric. Shrinkage and elongation were the features of a fabric material most considered when designing patterns for a circular knitted jacket.

The main purpose of this research is to develop a methodology for designing metadata application profiles(AP) and to design a comprehensive AP for Korea Art and Education Service(KACES), The process of developing a methodology is divided into three steps, analysis of standard metadata schema, analysis of user needs, and content analyses. Metadata principles and guidelines were utilized in designing a KACES AP along with the developed methodology in this study. This paper describes what role the methodology developed here plays in devising metadata elements. The paper also discusses the benefits of three methods for AP design. The study has values in that it provides implications for designing APs for other domains.

The purpose of this study is to suggest a designing method with excellent body suitability by analyzing clothingwearing porosity, comparing and analyzing patterns, and evaluating outer appearances by designing a prototype of study applied with design measurements for categories that have influence on the outer appearance of clothing through diverse research methods, by comparing and analyzing bunka and new bunka style basic pattern, which are proportional basic patterns most frequently used in schools for educational use to design bodice pattern for elderly women in their late 60s. As for the process of this study, the first stage selected study subjects, measured bodies. The second stage compared patterns of bunka and new bunka style basic pattern and evaluated outer appearances that deduced important pattern designing categories to design upper-torso bodice pattern of elderly women. The results of this study are as following ; As a result of comparing and analyzing bunka and new bunka style basic pattern, overall evaluation of outer appearance was excellent for new bunka style basic pattern, and bunka basic pattern received better reviews for the width and depth of front neck. In terms of waist circumference, waist front length, bust point location and bust point-bust point, bunka and new bunka style basic patterns showed a significant difference. new bunka style basic pattern had 4.5cm larger front armhole depth than bunka basic pattern, so it was evaluated to have more appropriate front armhole length, bust point location, and bust point-bust point. Through observation for primary excellent categories and precedent studies, 7 categories of front neck width, front neck depth, front interscye, back neck width, back neck depth, back interscye, and back armhole depth were deduced to have relations to the extra room around arm holes and waist that affect pattern designing method and porosity and evaluations of outer appearance.

With suffering financial crisis in 1997, Korea's fashion market has grown in the direction that satisfies the reasonable price and diverse consumer's sensitivity and needs. The aim of this study is to examine whether the cutting portion in the waist line is surely necessary for designing the jacket pattern in men's wear, by closely examining the effects of the cutting portion in the waist line on the external appearance and functionality given designing the jacket pattern in men's wear for the standard body type in 20s. The results of the study are as follows. As a result of evaluating the external appearance, when having evaluated by dividing into 14 items such as the whole surface, the side, and the back side, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items and, the significant difference was indicated in 10 items except 4 items. As a result of evaluating performance, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items among 25 items in the total. Next, the cutting portion in the waist line obtained the highest mark in 10 items for the experimental clothing with opening in 1.0cm. The next was indicated to be in order of the experimental clothing with 1.5cm and the experimental clothing with 0.5cm. Given seeing the above result, the cutting portion in the waist line given designing the jacket pattern for the standard body type in 20s could be known that the experimental clothing with the most excellent mark in the evaluation of performance was all the experimental clothing with 0.0cm whose waist line wasn't cut.
