Crack in Pavements have been continually increased aby water penetration Therefore, the cracks can result in deterioration of the pavements that could be extremely dangerous fro road users. Creak sealing work performed in outdoor is very dangerous, costly and labor intensive. To slove these problems, automated crack sealing systems have been developed. it Would be needed that work information related to crack sealing must be gathered in an effort to used for existing or future crack sealing work. Furthermore, work information related to crack sealing could be utilized in analyzing work productivity and condition. The primary objective of this study is to propose a PDA and Web-based system for work information management of crack sealing which enables to effectively interchange work information between head office and fieds, and to accurately collect work information. Finally, it is anticipated that the effective use of the developed PDA and web-based system would be able to effectively share work information, measure productivity, estimate costs as well as plan future work schedule.

The purpose of this research is to provide basic data for future home office design by surveying office workers' opinions about home-based working. The study is based on a survey done with 215 office workers in Seoul. The major findings are as follows. Home-based working is viewed as affirmative among office workers. Office workers thing that 3 days a week is desirable for working at home. The first reason why they want to work at home is 'having more free time for other interests,' the second one is 'being more creative or concentrating on work.'and the third one is 'reducing the stresses from the loaded tasks and relationships between colleagues'. While the first reason why they don't work at home is 'the notion that home is one thing and work is another.' the second one is 'lack of relationships between people.' and the third one is 'unable to concentrate on work because of many house chores.

Background and Objectives This study was conducted to investigate the change of total work and total work ratio for each set, peak heart rate during exercise, and blood lactate for each set during the 5-set bench press exercise at 75% one repetition maximum test (1-RM). Materials and Methods Seven men in their 20s with more than 6 months of experience doing resistance exercises were selected as subjects, and their 1-RM bench press was measured two weeks before the experiment and 75% 1-RM was measured one week before the experiment. In this study, total work was measured for each set, and heart rate was measured during rest and set-by-set exercise. Blood lactate was measured during rest time after each set. The raw data were analyzed by repeated one-way ANOVA. Results Total work and total work ratio decreased from 1 set to 4 sets (p < .05), p < .001), heart rate increased from stable at the start of exercise (p < .001) and decreased between 3 sets and 4 sets (p < .05). Blood lactate increased continuously up to 2 sets (p < .001, p < .01). Conclusion In conclusion, total work and heart rate decreased with muscle fatigue during exercise, and blood lactate continuously increased. The results of this study are expected to be useful references for constructing resistance exercise programs in the future.

Recently, much attention is paid on the office design be-cause the real world of work has undergone substantial changes, in both spatial and temporal aspects, due to the in-troduction of data processing technologies and new types of production. Today's renewed objectives of office are to define new physical space for work, to deal with economic and organizational changes. In the period of information, the purpose of an office is to improve the productivity for employers employees the comfort and vitality. Today's intellecture resources are necessary for the development in the modern business. The Hypid office, as an alternative in order to correspond the rapid changes, is proposed to give the space for satisfy-ing the basic desires of a human being-eating, resting and working. Accompanying with flexibility and comfortability, this office should include the space for personal purpose and the space for social purpose. Applying the concept of comfort like at home leads to re-lease a worker's stress from the society of information. The future office which is to enhance the quality of culture by in-tegrating indivisual, domestic and social life should commu-nicate efficiency, movement, energy, transformation.

Women's educational opportunities have been increasing and women's general advancement in higher education is the underlying factor behind the increasing number of female students in medical school. A number of issues affect female students and residents, including the existence of gender bias and sexual harassment, higher stress levels and lower levels of work satisfaction, the lack of role models in academic medicine, and conflict between work and family roles, including challenges surrounding having children. To what extent female and male medical students and residents make different career and life style choices is also an important issue. The shortage of doctors in surgical departments and maldistribution among specialties are of great concern in the health care system and medicine's future. We must prepare to solve these problems. New medical policies and educational approaches are needed for the future.

We hypothesize work jealousy can moderate the relationship between leader-member exchange (LMX) and two different work behaviors, counterproductive work behavior(CWB) and organizational citizenship behavior (OCB). The results supported our hypotheses and found an interaction between LMX and work jealousy such that the relationship between LMX and CWB is negative when jealousy is higher but not when jealousy is lower. We did not find an interaction between LMX and work jealousy on OCB, however. We test our hypotheses in a service organizational sample consisting of one hundred thirty-nine. Managerial implications and directors for future research are discussed.

The environment and the ecologic balance of the earth had been destructed by both man and ecological catastrophes and are no longer sustainable. We have no future unless we conserve our natural resourses and make efforts to change our basic patterns of consuming, production and recycling. Our earth had been contaminated without our recognition. We became indifferent to environmental problems and even more we hve lost our interest completely. To overcome this period of crisis, the concept of 'green imperative'has emerged. Since design powerfully influences our lives and the environment for good or ill, those at the forefront of design to consumers and the end-users can contribute to the well-being of the people and planet through new awareness of environmental and ecological based design. The spiritual awareness of green design will enrich the work of design through lasting performance of continuty and will make the future work.

Fume extracting welding gun is one of the promising options for reducing the welder's fume exposure. The performance of the gun was assessed on the basis of capture efficiency. Capture efficiencies were measured in a test chamber recommended by American Welding Society. The overall capture efficiency was turned out to be above 95%. But it did not include the effect of crossdraft existing in the real work environment because all experiments were conducted in a closed chamber. It thus needs more work in the future. In addition, the future directions for improving the pres ent commercial techniques of the gun were discussed.

This poster introduces the ongoing "Narrow-band Ca Photometry for Dwarf Spheroidal Galaxies" project and presents the latest results. The project aims to explain the formation and evolution of dwarf spheroidal galaxies by examining the structural properties of stellar populations as a function of metallicity. To overcome the lack of stars with known spectroscopic metallicities for dwarf spheroidal galaxies, we apply the hk index as a photometric metallicity indicator to three galaxies-Draco, Sextans, and Canes Venatici I. For all three galaxies, we found that metal-poor and metal-rich groups of red-giant-branch stars have distinct spatial distributions, in which metal-rich stars are centrally concentrated while metal-poor stars are relatively dispersed. In Sextans, we found an off-centered peak of metal-poor stars which is presumed to be a disrupting star cluster in this galaxy. We will discuss the implications of our results for the dwarf galaxy formation and possible directions on future work of this project.
