This research has measured the indoor environment of thirty hair salons, which are located on Gunsan-Si, Jeonlabbuk-Do, from April 1st to April 30th 2005, to examine the related factors on a work environment of hairdressers and a revelation of respiratory symptom, and has polled 260 hairdressers and 350 office workers. After measuring the physical environment of hair salons, the room temperature, the relative humidity and the illumination was in an agreeable range, and 60 percent of hair salons depended on the natural ventilation through the windows. The levels of acetone, toluene and xylene, which were measured at the hair salons, were all under the safety standards (p<0.05), but these are still harmful and volatile matters, so they can be bad for your health by the contact of skin and respiration. The harmful factors that affect a revelation of respiratory symptom were the group who has many exposures of permanent wave or bleaching/dyeing and not many experiences of hairdressing work, the group who smokes every day, and the group who never exercises at all (p<0.05). This result shows that there are possibilities of health problem for hairdressers from the constant and repeating hairdressing works with the exposure of chemicals such as the permanent, bleaching and dyeing. so that hairdressers recognize that they need appropriate ventilation facilities for their agreeable indoor-environments. And also, to prevent the direct exposure of chemicals as much as they can, they need to have an active management of an individual health care by wearing gloves, mask or something like that.

Despite the significance of ports as critical economic infrastructure, the berth facilities usually deteriorate due to heavy loading, unloading, aging, environmental weather conditions, marine growths, and lack of efficient maintenance management. Marine berths require proactive maintenance management to limit deterioration and defects as no berth facility is maintenance-free. Thus, delay in carrying out maintenance work for the marine berths can be devastating to the operational process involving ship entry, loading, and unloading operations. The aim of this research is to coordinate both operations work, and maintenance works that take place inside the berth of a local industrial port in Saudi Arabia, by developing a novel framework that integrates both works without affecting the efficiency and functionality of the berth. The study focused on defining the operational process of the port and identifying the elements with direct and indirect effects. In addition to determining the priority for the entry of ships inside the berth, it also identified the factors involved in designing a framework that included maintenance work as a component of the monthly berth occupancy schedule. By applying a mathematical model, a framework was established, which includes all the important elements of the process. As a result of the mathematical method formulation process, a database was designed that organizes and coordinates the operations of all berths within the port. This creates time to carry out the required maintenance work monthly as well as ease of coordination with the contractors responsible for the implementation of those works.

One of the critical issues in a sensor network concerns the detection of changes in data streams. Recently presented change detection schemes primarily use a sliding window model to detect changes. In such a model, a distance function is used to compare two sliding windows. Therefore, the performance of the change detection scheme is greatly influenced by the distance function. With regard to sensor nodes, however, energy consumption constitutes a critical design concern because the change detection scheme is implemented in a sensor node, which is a small battery-powered device. In this paper, we present a comparative study of various distance functions in terms of execution time, energy consumption, and detecting accuracy through simulation of speech signal data. The simulation result demonstrates that the Euclidean distance function has the highest performance while consuming a low amount of power. We believe our work is the first attempt to undertake a comparative study of distance functions in terms of execution time, energy consumption, and accuracy detection.

This study investigated the allowance usage practices and factors affecting saving behavior from 291 elementary school students in Susan. Frequency distributions, Pearson product-moment correlations, and logistic regression analysis were conducted by SPSS Windows. Two-fifths of the respondents did not regularly receive allowance. Many parents did not guide what children spent their money on before using it. Children spent their allowances on buying snacks, stationary, and playing in the game room. Only a small number of the respondents kept a record, but many children saved money. On the other hand, in the logistic regression analysis, the significant variables explaining children's saving behavior were parents' guidance before using allowance, record-keeping, and doing household work for an allowance. These results imply that parents are in the best position to give children positive experiences towards financial management.

정보화 시대에 한국어의 활발한 보급을 위해서는 다양한 모국어 사용자들의 학습 요구를 충족 시키는 한국어 코스웨어의 개발 및 통신망을 이용한 제공이 필요하다. 하지만, 외국어로서 한국어를 학습하고자 하는 학습자들을 위한 한국어 코스웨어는 영어와 일본어에 국한되어 있어서 유럽어를 모국어로 하는 학습자들의 한국어 학습 효율을 저하시키므로, 그들의 모국어로 된 한국어 코스웨어의 개발이 요구된다. 이러한 개발 단계에서 제일 처음 부딪히는 문제로 한글 윈도우(Windows)나 통신망(net-work) 환경에서 영어의 알파벳을 제외한 유럽어(European Languages) 특수문자의 입 출력이 불가능하다는 것이다. 따라서 비전산 전문가들이 손쉽게 코스웨어를 만들 수 있도록 개발된 기존의 저작 도구(authoring tool)로는 유럽어와 한글을 동시에 사용하는 한국어 학습 내용을 기술할 수 없다. 본 논문에서는 한국어 학습을 위한 원격 교육의 필요성 및 문제점을 알아보고 이를 바탕으로 설계한 유럽어 지원 한국어 코스웨어 개발 도구(developing tool)인 반디(BANDI)의 시스템 구성, 사용자 인터페이스 및 비전산 전문가인 학습 내용 개발자를 위한 스크립트 언어를 소개하였다.

In this study, we investigated a cooperative control system of assembly robots using wireless LAN. We developed two different types of robots to assemble three blocks on a workbench. Robot1 can assemble blocks on a workbench and Robot2 can carry blocks to Robot1. We constructed an ROS-based communication system and shared data. Three blocks and one workbench were recognized by camera-image processing By developing the UI using Windows programming language Visual C#, we evaluated the status of the robots and blocks and controlled the robots. The control system was developed by constructing all elements necessary for cooperative control, such as robot design and fabrication, motor control, ROS-based communication, and image processing. Thus, we completed fundamental tasks required for assembly.

Metaphor has been regarded as a simple methods for decorating languages for a long time, nowadays it has important role in creative thinking. Designers have had used metaphoric thoughts in art work design and architectural design as well as writers. But designers and art critics have not recognize its importance, in addition research about metaphor specially in design have not even started yet in any design areas. This research is on the line of studying automation design by explain mechanism of metaphoric design regarded as black box. Ronchamp Chapel design by Le Corbusier has been analyzed and some metaphoric processes has been logically described. In this process, properties of sound are transferred and used as window design to control lights.
