Technical advances contribute to the affluent life of human society. However, many people in underdeveloped countries live in poverty. Hence, many social groups are making efforts to improve their quality of life. The concept of appropriate technology is central to this endeavor. Utilization of appropriate technology in the textile design sector is one of the most efficient ways to make a living, while maintaining traditional skills and tools. It differs from the supply mechanism of advanced technology and products to people in the underdeveloped countries. In this study, we aimed to explore the fundamental ways toward self-reliance among citizens of substantially underdeveloped countries by integrating appropriate technology in the field of textile design. Application types were analyzed by researching cases that incorporate appropriate technology in textile design. These are classified into three ways based on underdeveloped regions, developed countries, and collaborative case with designers and companies. Improvement of the 3 aspects was approached in terms of product development, ongoing management and expansion popularity.

PURPOSES : In this study, design elements of rest areas for drowsy drivers are classified and appropriate criteria for each design element are presented. METHODS : By comparing and analyzing the design criteria for rest areas, the most appropriate installation criteria were suggested by considering the driving patterns of rest area users. RESULTS : As a result of the study, elements influencing the design of rest areas for drowsy drivers are suggested such as installation location and installation type. In addition, proper separation distance between resting areas was suggested considering vehicle flow, users' fatigue and physiological needs. Other criteria for rest areas were also suggested. CONCLUSIONS : Proper safety facilities were not installed in rest areas because appropriate criteria were not established. In this study, design elements were derived and installation criteria were designed so that rest areas could be used safely and conveniently.

This paper proposes eight groups of twenty nine scoring criteria that can help designers and practitioners to compare and select an appropriate methodology for a certain problem in designing product service system (PSS). PSS has been researched for more than a decade and is now becoming more and more popular in academia as well as industry. Despite that fact, the adoption of PSS is still limited for its potential. One of the main reasons is that designing PSS itself is a challenge. Designers and developers face difficulties in choosing appropriate PSS design methodologies for their projects so that they can design effective PSS offerings. By proposing eight groups of twenty nine scoring criteria, this paper enables a "step by step" process to identify the most appropriate design methodology for a company's PSS problem. An example is also introduced to illustrate the use of the proposed scoring criteria and provide a clear picture of how different design methodologies can be utilized at their best in terms of application.

In this paper, we deal with a process and layout design for producing a planned amount of Sikhye in a given limited time period under a reasonable production schedule. We represent a Sikhye production line as a vector N, the element of which denotes the number of tanks required in each process and our objective is to find an appropriate vector which minimizes the total investment cost. We suggest a systematic method for finding an appropriate N and an appropriate layout to N. In detail, first, we decide the required sequence of processes and the required operations for each process and we estimate standard operating times. Second, constructing a precedence diagram, we find a critical path in order to reduce the total production lead time for a batch of Sikhye. Third, given a limited N space, we manage to construct manually each production schedule using both the processing times of the critical operations and transfer times. Finally, we find an optimal vector N which gives a minimum investment cost and meets both the time constraint and quantity constraint. In addition, with the estimated relative size of each tank, we suggest an appropriate conceptual layout design including an expansion area for future demands, based on the span technique used in the field of architectural design.

It has been realized that the design codes and underlying design concept of high seismicity region may not be appropriate to low and moderate seismicity regions. The aim of this paper is to search seismic design strategies that are appropriate to moderate seismicity regions. The characteristics of seismic hazard in moderate seismicity regions are reviewed. The seismic responses of multi-span continuous bridges subjected to the ground shaking of moderate intensity are examined. The present code on seismic design of bridges is briefly reviewed. Based on these observations, design principles and strategies appropriate to the moderate seismicity regions are proposed for the multi-span continuous bridge

The purpose of this study is to identify the design features appropriate for the altered physical characteristics of pregnant women and formulate the direction of future design and development of maternity wear. A Delphi research method based on a panel of experts and pregnant women was used and the survey was conducted to determine the suitability of maternity wear. The survey found that A-line silhouette outerwear with round necklines, with wide sleeves and snap-button fastening on the front with a formal and decent look was considered appropriate as maternity and postpartum wear. Shirts and blouses long enough to cover the hip area to complement women's curvy and full figures, especially around the bust, waist, and hip areas during the later stages of pregnancy were found to be appropriate. Calf-length pleated skirts were comfortable to wear during pregnancy due to the abundant freedom of movement and space offered by pleats. Ankle-length straight leg pants were rated appropriate in terms of comfort and style both during late stages of pregnancy and at work postpartum. Dresses decorated with pleats from the armholes all the way down to the knees were found to provide high levels of comfort at the abdomen, chest, and hips, and considered appropriate. Based on this study results, a follow-up study will be conducted to examine the design of maternity wear during pregnancy as well as at work after pregnancy.

During the past decades, dramatic technology changes affected the life of billions of people around the globe. Although these changes resulted to economic benefits, mostly for the developed countries, the undiscerning development also resulted to many side effects, such as environment pollution, scarce natural resources, global warming, and an increase of the gap between "those who have" and "those who have not", among others. Also, since these developments were based on high technologies, they were not suitable for 90% of the underdeveloped countries. In this review, the possible ways of increasing the quality of life in underdeveloped countries are described, by providing adaptive solutions using appropriate technologies. Some successful applications of appropriate and intermediate technology are introduced, and the need for a new undergraduate education course of engineering design based on appropriate technology is proposed for Korea.

This research seeks to derive the design rainfalls through the L-moment with the test of homogeneity, independence and outlier of data on annual maximum daily rainfall in 38 Korean rainfall stations. To select the fit appropriate distribution of annual maximum daily rainfall data according to rainfall stations, applied were Generalized Extreme Value (GEV), Generalized Logistic (GLO) and Generalized Pareto (GPA) probability distributions were applied. and their aptness was judged Dusing an L-moment ratio diagram and the Kolmogorov-Smirnov (K-S) test, the aptitude was judged of applied distributions such as GEV, GLO and GPA. The GEV and GLO distributions were selected as the appropriate distributions. Their parameters were estimated Targetingfrom the observed and simulated annual maximum daily rainfalls and using Monte Carlo techniques, the parameters of GEV and GLO selected as suitable distributions were estimated and. dDesign rainfallss were then derived, using the L-moment. Appropriate design rainfalls were suggested by doing a comparative analysis of design rainfall from the GEV and GLO distributions according to rainfall stations.
