Recently, the structure of simulation environment is important issue in all fields. In case of the training for operating the machines which are costly such as airplanes or spaceships, simulators could be helpful for decreasing the costs and training effects by simulating real situation. When we get the driving license, too many peoples are waiting for their turns because of limited cars and testing spaces in Korea. To solve this problem, we've designed and developed the basic design for the simulators. We suggested the Computer 3D Simulation Model for practice of a drives's license. The concept of this simulator was from a 3D Racing-game which suit for driving exercise. We provide users with handle-controlled simulation setting in order that users feel reality as if they drive really through this simulator. We also use 'force-feedback' system which give handle vibration in case users collide against obstacles or exceed the line since users can absorb the simulation program and feel the sense for the real. This paper is the study about modeling the driving exercise model made use of 'computer 3D simulation', and producing and utilizing the simulator through this modeling.

The colour response reflects the cultural psychology of a nation or an ethnical group. Therefore the necessity and the importance of the investigations about the colours have been raised recently because of the possibilities for the diverse and practical applications in the modern industries. But there are certain tendencies for the investigations of the colours that depend upon the traditional and generalized approaches with which the meaning of the colour is used to be limited with the generalized interpretations that does not use to pay attention on the unique characteristics of a nation or an ethnical group. The object of this study has been planned and realized for the case study in Mexican City. In February of the year 2010 the colour response enquete had been realized during seven days and 128 peoples had participated. We've obtained information through the questionnaire method, getting the fact that the mexicans do response in some other ways. The results of this investigation tell us that the positive colours and the negative ones are different from the colours that the americans and the britains select. This investigation will serve as a basic study on the cultural psychology of the mexicans through the colours.

There are some studies about user's participation to reflect their desire and value on the planning of house by this time. These were constitution of unit space focused on the apartments, which is mostly theoretical. However, till completion of a construction work, it goes through various processes of some steps such as, buying building site, site planning, architectural planning and construction. In architectural planning process, it takes time for continuous discussion and revision between architects and users. Also changes of plan must of necessity be so because of in or outside conditions. So, right user's participation has its meaning that they take part in each step and portion of process faithfully on whole architectural processes. In this case, tenants of single house were decided and they already buy building site and lay out rules jointly. With this circumstance I've researched a kind of test the reflection on various desires and its acceptance in each steps through completion of a construction work, which is based on their participation.

The controversy about the burger button triggered in 2013 is that it is difficult to know what the hamburger button itself means and that it is difficult to predict what will happen when the button is clicked, Could. This controversy was found to be fundamentally out of touch, and it could be seen that it caused conflict with Apple's navigation structure with iOS. Therefore, in the case of Apple, it is often used in the form of a tab at the bottom instead of using the slide menu, but it is preferable to be used for the purpose of the hamburger button. I've looked through a variety of documents and found that the amount of content you want to offer on your app or the web is large, and there are five or more categories. And if a sub-category needs to exist in the main category like a large shopping mall, the hamburger button could provide the best UI. Apps and webs that can be curated, such as news and pinterest, are better used to enhance the search filter than to place a hamburger button, and for apps or the web that has a longer amount of content on a page Scrolling was available as an alternative to the burger button. In other words, depending on the amount of content to be provided, it is possible to decide whether to use the hamburger menu from the time of designing the information architecture.

We've reviewed 5,067 cases of claims by death that had occured for about 5 years from January, 1979 to October, 1983. As a result, We came to following conclusions; First, the greater part of deaths above mentioned were due to the Disease of Adult such as the Malignant neoplasm(18.4%), a Heart disease(10.4%), Liver cirrhosis(9.1%) and the Cerebrovascular disease(7.6%) as well as Accidental Death(26.5%), which were occupied by 72% of the whole. Second, classifying them by medical examination or non-medical, deaths in case of non-medical examination showed 80.8% of the. whole. And for age, sections ranging from 40 to 49 and from 30 to 39 took the overwhelming portions by 36.9% and 29.8% respectively, both of which showed 66.7% of the whole. Third, for the period elapsed, deaths within 1 year from the entrance showed 21.3% and that from 1 years to under 2 years, 19.9%. Thus the rate of early death under 2 years stood for 41.2% of the whole. Fourth, for occupation of the insureds, commerce occupied 20.4%, company employees 14.4%, agriculture 13.3%. These three categories marked 48.8% of the whole. From this, it appeared that the accidental death rate of the insured with the risky occupation was much greater than orthers.

This paper presents the autonomous swimming technology developed for an Autonomous Underwater Vehicle (AUV) operating in the underwater jacket structure environment. To prevent the position divergence of the inertial navigation system constructed for the primary navigation solution for the vehicle, we've developed kinds of marker-recognition based underwater localization methods using both of optical and acoustic cameras. However, these two methods all require the artificial markers to be located near to the cameras mounted on the vehicle. Therefore, in the case of the vehicle far away from the structure where the markers are usually mounted on, we may need alternative position-aiding solution to guarantee the navigation accuracy. For this purpose, we develop a sonar image processing based underwater localization method using a Forward Looking Sonar (FLS) mounted in front of the vehicle. The primary purpose of this FLS is to detect the obstacles in front of the vehicle. According to the detected obstacle(s), we apply an Occupancy Grid Map (OGM) based path planning algorithm to derive an obstacle collision-free reference path. Experimental studies are carried out in the water tank and also in the Pohang Yeongilman port sea environment to demonstrate the effectiveness of the proposed autonomous swimming technology.

This paper proposes a fuzzy logic controller(FLC) for DC-DC converters in order to obtain good l perfonnances that can not be achieved by linear control tc'Chniques in the presence of wide parameter v variations. 'While the standard controller uses error and derivative of e$\pi$or, the proposed controller uses state v variables. Such method is ve$\pi$ efficient in case of DC-DC converters and can guarantee both stable s small-signal responses and improved large signal responses. The presented approach method is general and c can be applied to any dc-dc converter topologies. Through the simulations of booster, we verify the pro[Xlsed C control tc'Chnique can give a satisfactory perfonnance.

Expansion of a roadway on a soft ground can cause settlement of the existing road during embankment construction due to the consolidation characteristics of the soft soil. Many problems related to construction and maintenance, such as deterioration of the surface, decreased safety, and decreased structural stability, could affect the existing road. This scenario is especially true if the roadway foundation is a deep thick soft ground. Therefore, engineers should carefully select a proper design based on the characteristics of the soil layer. In this study, the expansion of the second branch of the Namhae Expressway was selected as the target site because this expressway has been constructing on a soft soil layer approximately 50 m thick. The original design was reviewed, problems were discussed and alternative was proposed through value engineering job plan phases: investigation, speculation, evaluation, development and presentation. In addition, the proposed alternative was evaluated on cost, function and value improvement. Compared to the original design, the proposed alternative saved cost and improved the function and overall value.

In this article, I would like to analyze the conditions in applying the LCC method for each construction type by selecting 10 apartment complexes among the Turn-key projects which have been ongoing for the last 5 years. In addition, this article will identify the problems to the application of double landscape architecture and suggest improvement measures. Among the 10 case targets, a total of 151 LCC analyses were conducted, and the average application ratio placing for each construction type was shown in the following order: architecture (34.4%)> electricity (21.2%)>machine (18.5%)>civil engineering (13.2%)>landscape architecture (12.6%). As numbers show, landscape architecture was the lowest. The ratio of LCC reduction amount was shown in the following order: machine (32.1%)> architecture (23.9%)>electricity (23.4%)>civil engineering (17.5%)>landscape architecture (3.1%). The field of landscape architecture had a reduction amount that was about 5 to 6 times lower than civil engineering which had a similar number of LCC analysis cases. The total LCC analysis items of landscape architecture was 19, including 15 double packing material, 1 building covering, 1 grass planting, 1 planting infrastructure, and 1 facility. The following measures were suggested to promote LCC analysis in landscape architecture: first, set an analysis item that considers the construction expense ratio of landscape architecture; second, legal regulation of landscape architecture and expansion of its application; third, prepare VE/LCC standards which are suitable for landscape architecture.
