Most VE operation related to construction project is progressed in stage of planing or design phase, especially in case of domestic. It is encouraging fact and if you have VE process in stage of planning and design, you'll have experience a reduction of about 70% of total saving cost in which total construction process may occurred. However, recently the work of construction in overseas increase and almost is only construction-work, except planning and design process. As this reason, VE process for construction-work phase only is demanded in high necessity. VE in construction phase comes to accomplish intensively in the part which the design change does not follow, through know-how, equipment operating method and method of temporary-structure erection at the established construction-site learned, builders will be the possibility of reduction from 3% to 10% in constructive expense. This paper describes VE performing example in OO company's construction-work phase, and propose the methodology of VE performance in the phase of construction. And also it is aimed to extending VE applications into the overseas construction enterprise.

Musculoskeletal disorders show symptoms of pain and dysfunction caused by accumulation of minute damage on nerves and blood vessels which are related to specific body parts. This is more likely to occur in the elderly. In Korea, 40.3% of the agricultural population is over 65 years old. In these cases, the portion of musculoskeletal disorders is more than 80% in acute/chronic diseases related to agricultural work. Therefore, measures for physical health care and safety prevention of elderly farmers are needed. In this study, we intend to propose a method to measure musculoskeletal health condition through the motion recognition device and VR contents. For this, we analyze the agricultural work causing musculoskeletal disorders of farmers, and suggest a motion analysis algorithm that can measure the health condition of the musculoskeletal system. In addition, we are going to propose a training method customized for farmers on the basis of VR contents in order to prevent musculoskeletal disorders.

It is important to measure the excavator's work productivity that estimates the bucket's payloads on a process. If the bucket isn't filled at every working cycle, the excavator's operator has to drive the machine more to achieve his work quota. If bucket is filled over with the load, the other way around, the transferred object has to spread out on the workplace. That causes additional work to clean the site. This paper proposes a method that can estimate the bucket's payload to improve the excavator's work productivity. This method assumes that the excavator is a lumped mass system. And it uses a 3 points angle (boom link, arm link, swing) and 2 points pressure (boom cylinder's input port and output port) of measurable data. Depending on assumptions, the bucket's payload can be calculated by the payload's motion equation. And this suggested method can be verified by simple experiments.

Super high-rise mixed use buildings require a longer period for construction. Especially finishing work takes up about 40% of the whole construction period. Thus, finishing work is becoming an important factor in determining the construction period along with earth work and frame work. As the expected returns added by the reduction of the period and cost in constructing super high-rise mixed use buildings are huge, the expectations are now increasing for the possible gains. In this respect, as the period of finishing work is easier to be shortened than that of frame work, the efforts to acquire the technical knowledge to reduce the finishing work period are now being required. Accordingly, in this study, we aimed at suggesting the basic data for designing an economic plan for finishing-work procedure by analyzing the productivity of each work type of finishing work procedure on the basis of the execution and results of a construction method as a time-flexible finishing work plan. For this, we categorized the work types of finishing work procedure into each work unit and provided a work-system for each of them. Also, with case studies, we calculated the detailed amounts of the work-loads, required materials, productivity, and productivity index of the main work types of finishing work procedure and each of their separate work units as well as analyzed the relationship between the value results to suggest a better way to improve its productivity.

This study aims at applying Photoshop functions to digital make-up(DM) for aging effect based upon the knowledge of phrenology, comparing the result with that of the real or off-line make-up(OM) and identifying any possible difference between two methods: which contributes to understanding the potential and problems of DM at application level. This study aims at suggesting a method to apply computer graphics(CGs) to special effect make-up for aging effect through a case, contributing to attracting academic concerns and building theoretical frameworks for DM. It used 'Aging Process' in Adobe Photoshop CS4 Extended(CS4E) to change a young girl into a senior lady. In the process of DM, the study applies various tools and methods to making face wrinkled, finds the most effective way among them for each area of face, suggests a method to integrate the ways and shows the result of the method. Compared with OM, DM using CS4E is the less constrained work regarding procedure and time. Specifically, it can save the time tremendously because the reiterative operation of work can be omitted, when the same work is repeated, using 'Action' function which memorizes the history of the work. Once a DM work is produced, since it is durable, reusable and convertible to various images with additional operations, it seems very economical as well as highly promising to market the work through on-line sales. Regarding face features and skin, it reviewed literature in make-up and phrenology while it used Photoshop CS4 Extended tools to demonstrate a case of aging effect by combining and painting pictures of a young lady and a senior citizen.

Objectives: The purpose of this research was to analyze the influence of self-actualization needs, dependence on parents, and work-family balance stress affecting on the marriage friendly attitudes among the unmarried women in twenties and thirties. Method: The participants were 315 unmarried women connected by SNS. The data were collected by questionnaire method through SNS by the smart phone using by the snowball sampling method and analyzed by t-test, ANOVA, and hierarchical multiple regression analysis. Results: First, there were significant differences in the marriage friendly attitudes according to education level, religion, dating. In the case of college graduates, having religion and dating partner, unmarried women had more marriage friendly attitudes. Second, the results of multiple regression showed that the marriage friendly attitudes among unmarried women was significantly influenced by education, religion, and the humanity factor among the self-actualization needs, emotional dependence on parents and work-family balance stress. In addition, the humanity factor among the self-actualization needs was found to be the most influential factor on the marriage friendly attitudes among unmarried women in this study. Conclusion: This study suggests the importance of emphasizing humanity education, having the emotional close relationship with the parents, and enforcing social systems for work-family balance for the greater marriage friendly attitudes of unmarried women in twenties and thirties.

The measured equation of invariance (MEI) method was introduced as a way to determine the electromagnetic fields scattered from discrete objects. Unlike more traditional numerical methods, MEI method over conventional methods over conventional methods are very substantial. In this work, Haar wavelets are applied to the measured equation of invariance (MEI) to solve two-dimensional scattering problem. We refer to "MEI method with wavelets" as "Wavelet MEI method". The proposed method leads to a significant saving in the CPU time compared to the MEI method that does not use wavelets as metrons. The results presented in this work promise that the Wavelet MEI method can give an accurate result quickly. We believe it is the first time that wavelets have been applied in conjunction with the MEI method to solve this scattering problem.

When a body including a crack inside is subjected to the compressive forces, the crack is closed and sliding occurs on the crack surfaces. In this work, a subsurface crack subjected to a static or moving compressive load is analyzed with the finite element method considering friction on the crack surface. The friction on the crack surface is assumed to follow the Coulomb friction law. A numerical method based on the finite element method and iterative method is applied in this work. And the result is compared with the frictional contact of crack by ANSYS using contact 12 element. The numerical results of two methods are compared with the wellknown analytical solutions, and the accuracy of iterative method is checked..

국내 게임산업현장에서 게임시스템 기획은 기획자가 게임컨셉을 만족하는 게임플레이가 이루어지는 게임메카닉스 시스템을 데이터구조적 설계방법으로 creative design 작업관점에서 초기적으로 설계하는 작업이다. 그러나 프로그래머는 구현을 위해 기획내용을 바탕으로 게임시스템을 객체지향적 방법으로 engineering design 작업관점에서 설계한다. 이러한 작업방식은 기획자와 프로그래머 사이에 의사소통 과정에서 다양한 오류들과 작업결과물의 미스매칭 오류들의 발생가능성이 높다. 이 문제를 해결하기 위해, 본 논문에서는 기획자가 객체지향적 설계방법으로 게임시스템을 기획하는 방법을 제안하였다. 제안하는 방법은 객체지향적 SW 개발 가이드라인인 GRAPPLE을 기반으로 기획자의 게임시스템 기획에 적합하도록 커스터마이징한 것이다. 본 논문에서 제안한 게임시스템 기획방법의 효용성을 조사하기 위해 국내 게임산업체에 근무하는 게임시스템 기획자 10명을 대상으로 설문조사하였다. 설문 조사결과는 거의 모든 대상자들이 제안한 방법의 효용성이 '조금 이상' 있음으로 나타났다.

Purpose: The purposes of this study are to examine and to compare factors causing stress and coping methods between nephrology nurses working in the Hospitals of University and the Hemodialysis Clinics. Method: Data were collected by a direct survey method using a questionnaire from August 13 to August 31, 2001. The sample of 137 nephrology nurses in the twenty-one Hospitals of University and 168 nephrology nurses in the twenty-six Hemodialysis Clinics were selected for a total sample of 305 nurses. Result: Stress according to general characteristics showed a significant difference in religion and in the level of satisfaction for their work. Stress score was the highest in the nurses whose religion was Buddhism(F=4.846, P=0.008) and in the group with 'dissatisfied' for the work in the Hemodialysis unit(F=3.193, P=0.014). The results analyzed coping method according to the general characteristics had a significant difference only in religion(F=16.237, P=0.000). The score for the coping method was the highest in Buddism. The score compared the satisfaction level for their work according to the hospital type, were 3.55 in the Hospital of University group and 3.35 in the Hemodialysis clinic group and these two values were significant different(p<0.05). The mean score of the stress nephrology nurses in the Hospitals of University is 2.79 and that of the stress nephrology nurses in the Hemodialysis clinics is 2.78 of 4 point scale. Among the factors causing stress, items related nursing work and conflict in nurse-patient relationship significantly caused more stress to the nephrology nurses in the Hospitals of University than to those in the Hemodialysis clinics(p<0.05). Conclusion: This study suggests that there were some differences in the stress and coping methods between nephrology nurses in the hospitals of University and the Hemodialysis clinics. Further study related to stress management program is needed to decrease stress and use effective coping methods.
