A study on techniques to evaluate auditorium assignment visible efficiency using three-dimensional simulation. The most important thing to be considered is to ensure the visibility to the podium upon assigning auditorium of venues, classrooms or seminar rooms. However, since there are so many variables to be considered such as the form of the stage, the area and height of the stage, size of screen, and the distance and angle of the auditorium from the podium, the methods to assign auditorium are staying at the level of basic for a long time. Thus, in this study, we proposed simulation methodology to quantitatively evaluate the three-dimensional visible efficiency based on Visual Graph Analysis (VGA) theory. After analytical methodology manufactures application, it sets examples of visibility depending on location of screen, visibility depending on degree of height difference and visibility about three-dimensional Mass Zoning like a stage and verifies the efficacy. In addition, based on results, visibility expectation curve is drawn and the method to calculate the stepped height depending on necessary visibility is proposed.

Recently, in Korea the birthrate is declining and the average life span has been increasing. Thus, compared to the previous periods nowadays, older people are required to work. Even elderly people are rejoining the workforce. Korean companies set the retirement age between 55 and 60 years of age, however, accidents occur frequently. Thus, it becomes necessary to evaluate the ability of the elderly person. Since the required function of the worker varies from job to job the evaluation of the capability must also be conducted according to the desired functions. One of the methods used in this study is the continuous control knob to evaluate the tracking control ability to investigate the relationship of manual dexterity and age. The result of the study Indicates that the manual dexterity decreases with age. However, there are differences among individuals. The individuals lifestyle affected the manual dexterity of that individual. As a result, a company may use the manual dexterity as an measure to evaluate the elderly persons work ability.

This paper is about the use of existing evaluation methods, which evaluate learning determined by the score of an exam, which is either a multiple-choice type or single choice type question. These scores don't show the objective evaluations that cause some negative opinions about the scores. In this paper, we propose that the evaluation of the methods of self-directed learning use the triangle-type function of the fuzzy theory so that the learner can objectively evaluate their own learning ability. The proposed method classifies the result of learning into three fuzzy grades to calculate membership, and evaluate the result of an exam according to the final fuzzy grade degree as applied to the fuzzy grade sheets.

In order to improve areas lagged behind well-developed others ing the balanced national development. Development Promotion Areas(DPA)was designated in 1996. This study aims to develop a rational evaluation system for projects of DPA. This system has 3 evaluation steps. The first step is to evaluate 10-unit operations which are tourism, recreation, road, water supply and drainage, life environment, and so on. The second step is to evaluate 3 sub-programs such as tourism and recreation, local infrastructures and specialized industry. The third step is to evaluate comprehensively in entire area. A tentative system for project evaluation of DPA was proposed by brainstorming of expert-group. Weighting values of items in PDA were calculated through pair-comparison works of expert group using stepwise matrix sheets by AHP(Analytic Hierarchy Process).

The objictive of this study is to analyze regional drought using agricultural drought indicator. Toforecast and evaluate the drought, the drought indices for agriculture were applied. In the present drought preparedness plans of Ministry of Agriculture and Forestry (MAF), it is prescribed that the preparedness levels should be classified by considering the precipitation, reservoir storage, soil moisture in paddy and upland, and the growing status of crops. There are many drought index to analyze and evaluate the drought. However, these indices do not exactly explain all drought events. Thus, we select 4 drought indices to evaluate agricultural drought:reservoir storage index, 3-month delayed SPI, mean rainfall index, and dry day index. Using these ineices, six drought stages are classified. The results show that agricultural drought could be apprppriately analyzed and evaluated by agricultural drought stage and four drought indices.

In this study, we suggest that several approaches to evaluate the collision acceleration value of a car in the article 35 and the guideline 16 of Korean rolling stock safety regulation. There are various methods to evaluate collision acceleration such as; a displacement comparison method by the double integration of filtered acceleration data, a velocity comparison method by the integration of filtered acceleration data, an analysis method of time-velocity curve, or a differential method of time-velocity curve. We compared these methods one another using 1D dynamic simulation model composed of nonlinear dampers, springs and bars, and masses. Also, we applied these methods to a hybrid model, which is made of 3D shell element model and 2D collision dynamics model, in order to evaluate whether 1D force-displacement curve modeling for energy absorbing structures have an effect on the collision acceleration levels or not.
