This work is for examining a simplified equation based on the rational formula, which can easily decide storm-water detention volume in small urban catchments. The storm-water detention volume is determined by the inflow hydrograph flowing to detention basin and the outflow hydrograph discharged from the detention basin. The ratio of average outflow over the period of rainfall duration against allowable discharge was 0.5 in former simplified equation. But this research has found that the average outflow ratio depends on the storage methodology. In the case of the on-line storage method, the average outflow ratio is a function of the time of concentration of the catchments and rainfall duration, which ranged from 0.5~1.0. In the case of the off-line storage method, the average ratio is a function of peak discharge and allowable discharge except above time of concentration and rainfall duration, where its function value ranged from 1.0~2.0. When applying this equation to small catchment in Mokpo city, South Korea, we could easily calculate the relation curve between the storm-water detention volume and allowable discharge.

The modern period was the time that the most radical and extensive social and mental changes were occurring throughout the history, and modernism was prevailing as a general cognition system of people. Modernism, which carries principles of progress, belief in application of scientific technology, worship of reason, ideal of liberty as a col-e value of civilization, was plated as a leading ideology in the realm of society, culture and art In the early 20th century. In this study, the formative characteristics of modernism seen in architecture and fashion are analogized and analyzed in four ways ell the basis of the theory of p. Greenhalgh. First, 'Standardization for mass-production', which is analogized which P. Greenhalgh's 'Decompart-mentalisation', 'Social Morality', and' Technology'. Standardization for mass-production in architecture focuses on the development of a design prototype in order to mass produce; the development of ready-made clothes is actively done ill the fashion area for the same purpose as well. Second, 'Rational functionality' coming from P. Greenhalgh's 'The total work of art' and 'Function'. While rational functionality in architecture puts an emphasis on the rational operation of all the functions in regard to the relation between each part and the whole, rational functionality in fashion call be mainly seen in a dramatic increase in physical activity which could be hardly found before the modernism period. Namely, all the fashion design elements are developed for a certain rational and functional design on each part as well as on the whole in order to greatly increase physical activity. Third, 'the pursuit for genuineness of objects and universality of beauty' is on the analogy of P Greenhalgh's 'Truth', 'Anti-historicism', 'Abstraction', 'Internationalism/Universality'. This idea is adopted in architecture in the form of design of geometrical abstraction. In the same way, design using geometrical abstraction comes to have a significant meaning in fashion of the modernism period. So to speak, modernism architecture and fashion can be reborn to become an inter·national style by giving up the decorative and regional design prevailing before modernism and by expressing universal aesthetics in the form of simplicity and abstraction instead. Fourth, 'Expression of progress through a change in a viewpoint' stems from P. Greenhalgh's 'Progress', 'Transformation of Consciousness', 'Theology'. In architecture, this concept appears by using new construction materials and methods and by representing new aesthetical idea. As a result, it makes it possible for people to make progress for better lives. Like in architecture, new attempts for material application and processing are made in fashion. This gives rise to a general change in a viewpoint related to fashion, so that a flew fashion design which there has never been before can come out.

This article proposes a new time-based depreciation method using the accumulated depreciation rate function. The method can systematically compute the depreciation charge of each period, in every case where the charge is constant or decreasing or increasing, and solve the problems of depreciation methods currently used, by obtaining the accumulated depreciation charge at any given time. We can choose diverse rational depreciation types for the characteristic of every asset with the new method, and compute the depreciation charge with consistency in all cases where assets are owned for partial period.

The purpose of this study was to determine the level of reasonable consumer habits of adolescents based on their consumer socialization, consumer education, and purchasing skills, and to determine their brand orientation based on facts that adolescent years is the determining period for consumer socialization, that their role as consumers take up relative importance, and that consumer habits during this period is extremely important. The directions of consumer education for forming a reasonable consumer culture for adolescents based on the results of the study are presented as follows. First, by conducting a training program for consumer counselor that supports courses such as consumer aid that are held for adolescent consumers, adolescents must be led towards logical purchase habits and to practice reasonable purchase habits. Second, since consumer attitude that is learned and formed since youth is important, discussion sessions as well as consumer education programs that can foster proper consumer knowledge, attitude, and function needs to be developed by schools and the government. Third, This can form improper consumption values such as over consumptions, conspicuous consumption, and impulsive purchase that may appear in their adult years; therefore, a consumer education program must be continued in the homes, schools, and by the government so that adolescents can learn manage reasonable consumer values and consumer habits.

The mechanization of production facilities being made rapid progress, and its function being diversified and complicated for industrialized period, the relation between machine and Its operator brings about many problems which are concerned with accident. In these circumstance, the purpose of industrial safety can not be properly achieved as considered by only one side of machine or man. Therefore, it is necessary to study how to cope with the safety of man-machine system. It has to be considered in the above mentioned contents that safety management can not be attained through only technique of numerical control. The cause of accident being studied scientifically, the service of safety problems has to be systematized and operated in rational safety organization. The purpose of this thesis is to consider preventing and decreasing industrial accident from production system field by means of the improvement of worker's own safety consciousness and introducing the function of safety management to the duties of labour union.

This article presents detailed explanations of the depreciation method using the accumulated depreciation rate function(ADRF) proposed by the author previously, for the practical application. ADRF provides a value of accumulated depreciation rate on the total depreciation charge at any given time, therefore it can be used in a time-based depreciation method. Since the depreciation charge of each period can be systematically computed with ADRF, in every case where the charge is constant or decreasing or increasing, we can choose diverse rational depreciation types for the characteristic of every asset. Also, since the ADRF is the continuous function of time, we can compute the depreciation charge with consistency in cases where assets are owned for partial period. However, we should determine the value of parameter of ADRF. We give some data on the problem.

The runoff coefficient for a block paved area is determined with regional rainfall distribution. The Rational Method is a basic equation of a drainage system design and is a function of runoff coefficient, rainfall intensity and area. A runoff coefficient is the ratio of rainfall intensity and runoff. The rainfall intensity which is a function of the return period and rainfall duration differs by region. Therefore the runoff coefficient varies regionally even though there is the same return period and rainfall duration. The ratio of rainfall intensity and rainfall duration is decided by the loss of rainfall. The constant infiltration capacity of Horton's equation is adopted to determine the loss of rainfall. As time passed, the joint of the block paved area through which the infiltration occurs is covered by pollution material, sandy dust, pollen and is hardened by foot pressure, so the constant infiltration capacity may decrease. Six different sites were selected to verify the assumption of the constant infiltration capacity decrease and 10 year return period. 10, 20, and 30 minute rainfall duration were applied to calculate rainfall intensity. The results indicate that the Horton's constant infiltration capacity decreases over time and the minimum constant infiltration capacity is selected to compute runoff coefficients. The runoff coefficients varied by region ranging from $0.94{\sim}0.84$ for 10 minute of rainfall duration.

This paper aims at studying on the medium of cultural interchange regarding who did and how to introduced the new trend of architecture during the period of Koryo Dynasty. Before the era of Koryo Dynasty, Kyungjang(Sutra Pitaka, 經藏) was mainly centered in Kyeongnu with a substantial function of storage. In the early Koryo Dynasty, however, Daejangjeon(大藏殿), which was spatialized for worship, began to appear. Normally, fixed walls were installed and the Sutras were enshrined inside Daejangjeon, while Jeonryunjang (revolving wheel sutras), a type of rational bookshelf, was introduced, and a new trend became developed in Kyungjang construction. Jeonryunjang(revolving wheel sutras, 轉輪藏) is a dharma instrument with a rotational function so that one revolution gives an effect of reading the enshrined Sutra one time, and began to be created actively in the period of the Northern Song. It is considered that the introduction of Jeonryunjang(revolving wheel sutras) to Daejangjeon was resulted from Haejokuksa(慧照國師) Damjin(曇眞) who visited the Kangnam areas in the Northern Song at that time. The Kangjeol areas in the Northern Song, where Damjin concentratively itinerated three times, were the place in which Jeonryunjang was created in many temples. Since Damjin, historical materials and excavated data regarding constructing Jeonryunjang have been discovered in the Buddhist temples, which are related to his pupils and dharma lineage. The only existing Jeonryunjang of Yongmusa Temple in Korea is the one that Joeung Daesunsa, who succeeded to the dharma lineage of Haesokuksa, promoted, and supports strongly such introduction of Jeonryunjang by Haesokuksa.

The study on architecture can be started with the aesthetic attitude which cognizes it as the art of the space. Architectural space as the subject of the aesthetical study, however, has been ignored such a long period though it should be centered of the whole architectural theory. Even it has not been dealt with independently but just only as a part of aesthetic or artistic field. Also it is true that academic approach to the architectural space as per the aesthetic cognition has not been done so satisfactorily. This study, therefore, aims at prescribing compositional scope from aesthetic cognition of architecture understanding the rational function, mechanic structure, and artistic beauty by man's subject standard of judgement as per the space, the special sphere of architecture. For the absolves, the architectural space in this study is not approached as the spatial art with the meaning of being included the arts general, but with the meaning of intrinsic peculiarity of architecture, based both in practicality of scientific concept and arts of the aesthetic notiov. In order words, the essence of architecture can be prescribed as the architectural realities as the functional, formal and symbolical space not simply the spatial art, and its real but aesthetic meaning can be cognized aesthetically.
