The meaning of light is not always developed aspect in process of architecture history as essence worth of the architecture. It means that architectural light is not affected simple development of civilization, but it has more complex aspect. The technology of applying architecture has continuous development of society that light is possible to extend quantity by development of technology because light is component not simple material or tools but strong worthy aspect, quality development of architecture comes true by exact understanding and application. Conversion from medieval society to modern society begins at the Industrial Revolution has new skills and materials, the architectural conform general space filled with non-characteristic light, and it gives rising to pursuit Utopia is not exist frequently. In result, light of metaphysical meaning is diminished and exterminated. In other hand light seems to be tools by development of technology in modern society, recovering its own meaning in other aspect. That light makes perfect image of architecture not by finite meaning only for simple space but by expressing strongly point that unify the whole architectural composition. Light is free from partial material of architecture. Light activates major composition through high-technology, and has possibility to carry out the essential worth animate architecture. The light expresses relative speciality for sense of place recognizes major component which the human being lives in and conform the real meaning of architecture.

This study is performed to determine the priorites of the evaluation factors for the improvement of fire emergency medical service by increasing it's efficiency to protect the people's lives effectively, and by recognizing it's mid-long term development. Based on the output of the analysis, the critical evaluation factors of the fire emergency medical services to be improved shall be identified, and shall be intended to use strategically for increasing the efficiency of all the activity in the EMT service, and also for providing the basic date to product and manage the good quality services. To calculate the priority of the evaluation factor for each level as shown on this study, AHP(anaysis hierarchy process) with pairwise comparison method is applied. According to the priority analysis for the evaluation factors in main category (evaluation zone), 'medical service professional aspect' is recognized as highest one, and 'service infrastructure aspect', 'service management aspect' are indicated in order. According to the priority analysis for the evaluation factors in evaluation index, 'professional personal arrangement' in the service infrastructure aspect, 'appropriateness and timeliness of emergency medical care' in the medical service professional aspect, and 'clinical training' in the service management aspect are respectively recognized as most important factors.

In this study, the effect of aspect ratio and soil strength on the skin friction for barrette pile was evaluated using numerical analysis. The back analysis was conducted to obtain the friction coefficient between pile and soil using the experimental results of the static pile load test for the barrette pile installed at OOsite in Busan. A total of 36 simulations for the static pile load test were also conducted with respect to various aspect ratios and soil strengths. It was found that the skin friction increases as the aspect ratio increases and the change in increasing rate was remarkable near the ultimate skin friction. In addition, the effect of aspect ratio on the skin friction was investigated when the strength of soil at pile tip was varied.

The study is to investigate the free vibration of antisymmetric angle-ply conical shells having non-uniform sinusoidal thickness variation. The arbitrarily varying thickness is considered in the axial direction of the shell. The vibrational behavior of shear deformable conical shells is analyzed for three different support conditions. The coupled differential equations in terms displacement and rotational functions are obtained. These displacement and rotational functions are invariantly approximated using cubic spline. A generalized eigenvalue problem is obtained and solved numerically for an eigenfrequency parameter and an associated eigenvector of spline coefficients. The vibration characteristic of the shells is examined for cone angle, aspect ratio, sinusoidal thickness variation, layer number, stacking sequence, and boundary conditions.

Cumulative trauma disorders (CTD) refer to a category of physical signs and symptoms due to chronic musculoskeletal injuries where the antecedents appear to be related to some aspect of repetitive work which can be found commonly in modern industries. This paper describes impacts of CTD on modern industry and summarizes recent resent research efforts and suggests an ergonomic program to prevent incident of CTD in hand-intensive industry.

This paper presents the results of experiments which compare the software complexity between programming languages, i.e, FORTRAN IV and FORTRAN 77, PASCAL and C language, respectively. Each experiment is performed to compare the complexity between programs of same problems using Halstead's method based on operator, and McCabe's based on data flow. As the results of 25 test programs experiments, FORTRAN 77 languages shows superiority to FORTRAN IV languages, and C than that of PASCAL languages, in the aspect of the global software complexity.

탄소강 평활재 및 미소결함재를 사용하여, 미소 정류크랙의 크랙 개폐구거동의 상세한 관찰과 초기결함을 상정한 미소 원공과의 상호 한계크기의 비교 검토를 통하여, 다음과 같은 결론을 얻었다. 평활재의 정규크랙은, 피로과정중에 압축잔류응역이 크랙선단의 개구를 억제하는 것에 의하여 정류하게 되고, 그 크기는 평활재의 피로한도를 저하시키지 않은 미소 원공의 한계크기와 거의 일치하여, 두 경우가 역학적으로 거의 등가함을 시사해 주고 있다.

This paper presents a model which may be used in optimal control of the Man-Machine systems in the aspect of information transmission. For this, we divided information into human parts and machine parts, and consider minimum error principle as a machine operating logic. Furthermore, we take the maximum information principle as a human information operating logic. This can be done in considering the Fisher Information and its transformed type, information inequality.

The present automated manufacturing environment is very different when the classical statiscal process control method based on batch processing were used. Therefore these must be replaced by automated statiscal process control method. In this point of view , this study intends to develop the automated statiscal process control method which can be implemented in the proesent automated manufacturing environment . Specially this study suggested modified control limit line and developed the rule to identify the special cause of the manufacturing process in the aspect of the ppm manegement.

Improve of productivity is a key for the development of a company, which can be pursued in the apect of material factor and personal factor. And the motives of worker for their job is more influenced by the chance of incentive compensation or self-development than by participation in management and safety of their post ect. Contingency theory is one of the theories that cope with this study Therfore, this study describes incentive compensation for satisfying worker desire related company's productivity, and be presented to the aspect of contingency accounting.
