In high-risk workplaces where communication is not possible, such as deforestation, it is necessary to use equipment that monitors the worker's situation in real time and obtains information according to the worker's location in case of an emergency. This paper analyzes the development and demonstration experiments of smart hard hats for deforestation workers to maintain a safe working environment. The developed smart helmet identifies the location of the worker based on the UWB signal for location estimation, and it is necessary to keep the distance between the workers not too close. UWB, Gyro, and LoRa are used to communicate even in the communication shadow area. It is used to provide a safe working environment such as improved construction to reduce worker risks and risks in forest working environments.

Satellite and aerial images are very useful means to monitor ecological and environmental situation. Nowadays more and more officials at Ministry of Environment in Korea need to access and use these image data through networks like internet or intranet. However it is very hard to manage and service these image data through internet or intranet, because of its size problem. In this paper very large image data service system for Ministry of Environment is constructed on web environment using image compression and web based image processing technology. Through this system, not only can officials in Ministry of Environment access and use all the image data but also can achieve several image processing effects on web environment. Moreover officials can retrieve attribute information from vector GIS data that are also integrated with the system.

Like other artificial architectures, the residence is also hard to be changed after once it has ever been built because its life is approximately estimated up to 20years. Furthermore, it may give big effect to residents as the life Quality. Because of these specificities, it seems to be important to forecast how demand of residential market will be changed and what kind of residential environment should be built in the future. First of all, we should consider about what is a current situation of residential environment in this country before beginning researching resident preferences. In addition, we will also research current and new residential style in other country, which should be concerned in. Finally, this study is researched by domestic male and female residents in their twenties and four ties on purpose to gain information what type of resident style they want and to suggest new ways of future residential environment.

The objective of this study was to investigate news on the detergent to know transition of the detergent and the social environment in the Korean daily newspapers. The relationship between social environment and detergent were analyzed articles of Mail, Dong-a and Cho-seunilbo from 1910\`s to 1998\`s. The results were as follows. Times of ancient detergent had been existed natural cleaners. Times of hard-type detergent was happened problems the environmental pollution and the safty of the human body. Times of soft -type detergent needed development new detergents for decrease of environmental pollution. Times of detergent on the affinity environment were used the refill products, mark of environmental protection for decrease the pollution of the environment.

In many manufacturing occupations, industrial workers reported foot or lower leg problems such as discomfort, pain or orthopedic deformities. This study investigated the effects of two different working conditions upon assembly worker's perception of discomfort and foot pain associated with various body parts. Twenty-three male volunteers performed work in the factory. Ergonomic intervention has been to modify the flooring in an attempt to alleviate the problems associated with constrained standing and walking work. The worker's standing conditions consisted of standing on a hard floor while wearing shoe insoles. Questions were asked regarding body discomfort and foot pain. Significant differences in body discomfort and foot pain were found when comparing the overall effects of wearing shoe insoles on a hard floor (p<.05). This investigation indicated that shoe insoles reduced body discomfort and foot pain (p<.05).

Urban architecture density is getting higher, and this trend is expected to continue in the future. Therefore, skyscrapers are being brought into relief as future alternative architecture beyond symbolic meaning in the aspect of demand and supply of urban space. However, skyscrapers which were newly built have many problems such as consumption of enormous amounts of energy, destruction of natural environment, and traffic jam. For this reason, environment-friendly skyscrapers based on the concept such as Green Building and Green Skyscraper started to be built around the world. However, plans or evaluation standards, which take account of the environment-friendly aspect of skyscrapers, leave much to be desired. And especially it is hard to find environment-friendly skyscrapers. Therefore, this study aims to establish the concept of environment-friendly skyscrapers that has not properly been defined, and to find realistic planning methods and practical alternatives through the analysis of the works that have brilliant ideas about environment-friendly architectural method. From the perspective of architectural planning, we did case analysis focused on site planning, form planning, elevation and floor planning, and tried to give useful ideas for high-rise architectural planning in Korea by finding practical solution focused on the active use of natural energy, saving resources, the reduction of wastes, natural architectural environment design and natural friendly system from the view of environment-friendly technological analysis.

In this paper we have designed and implemented a method of using extended memory and hard disk space as a data buffer for application programs to allow handling of large data files in DOS environment. We use a part of the conventional DOS memory as a buffer cache which allows the application program to use extended memory and hard disks transparently. Using buffer cache also allows some speed improvement for the application program. We have also implemented a number of functions to allow easier handling of pointer operations used by application programs.

Nowadays, with the proliferation of Web services, developer and user can implement a complex application by composing registered Web services. In this trend, the quality of service of a composite Web service is of crucial importance for today's Service Oriented Computing (SOC) environment. But the global optimization of a composite Web service satisfying given QoS is classified to NP-hard problem. To solve this problem, we propose K-way Super node approach and show the effect of it from experimental results.

In the recent society of knowledge industry, a changed phenomenon of domestic corporate culture, Work Smart working in creative and various ways beyond time and space is emerged from Work Hard working just hard. Thus, many corporations are trying to configure the emotional space beside the work space to make effective and creative achievements in free work environment out of rigid organizational culture in the past. This space is called Amenity space which enables to implement physical and psychological healings simultaneously and this is not a place for rest like in the past industry society. This research suggests distinctive characteristics of other amenity furniture unlike general furniture by analyzing the variously suggested change of forms of amenity furniture for Work Smart and the changes of configuring key factors such as forms, structures and functions of amenity furniture.
