Recycled polypropylene (RPP) - Wood Saw Dust (WSD) composites with and without acetylation of filler were produced at different filler loading (15%, 25%, 35% and 45% w/w) and filler size (300, 212 and $100{\mu}m$). The RPP-WSD was compounded using a Haake Rheodrive 500 twin screw compounder at $190^{\circ}C$ at 8 MPa for 30 minutes. The mechanical properties and water absorption properties of modified and unmodified WSD-PP composites were investigated. Acetylation of WSD improved the mechanical and water absorption characteristic of composites. The decrease of filler size (300 to $100{\mu}m$) of the unmodified and acetylated WSD showed increase of tensile strength and impact properties. The composites exhibited higher tensile modulus properties as the filler loading increased (15% to 45%). However tensile strength, elongation at break and impact strength showed the opposite phenomenon. Water absorption increased as the mesh number and filler loading increased. With acetylation, lower moisture absorption was observed as compared to unmodified WSD. The failure mechanism from impact fracture of the filler-matrix interface with and without acetylation was analyzed using Scanning Electron Microscope (SEM).

This study identified the characteristic and meaning of flow experience through the experiences related to fashion models' role performance; subsequently, the following findings were obtained. First, fashion models' flow experience could be divided into characteristics such as temporality, spatiality, relationality, physicalness and pleasure. Second, the process of this flow experience ultimately led to the complete moment. The complete moment can be said to be the aesthetic experience that provides both the meaningful experience and the aesthetic pleasure; it is the experiential knowledge at the dimension of mysterious integration that their body and mind are integrated into one. The beauty that fashion models exercise at the aspect of this aesthetic experience is that of performance and is an individual physical movement where they perceive their role and exercise their inner ability to express their costume most beautifully. Accordingly, the beauty of performance can be said to mean that the fashion show was successfully held by inducing both the performer and the audience into an aesthetic response. The process of specialized planning and preparation is required for fashion models to exercise the beauty of performance at the complete movement reached through flow experience and a successful fashion show. Diverse elements of the fashion show should be more organically constituted through such a process. Fashion models should exert efforts to embody acts such as walking, posing and turning through the performance of their excellent role as well as develop a training program to complete it.

본 연구에서는 호우 방향성에 의한 유역 유출응답 특성을 살펴보았다. 이를 위해 호우와 하천망의 방향적 특성을 확률밀도함수로 정량화하였고, 각 방향성 함수를 회선적분하여 호우 방향성의 고려 유무에 따른 유출응답 특성을 비교하였다. 그 결과, 호우 방향성을 고려한 유출모의 결과는 호우 방향성을 고려하지 않은 경우에 비해 관측 유출자료와 더욱 유사함을 알 수 있었다. 이러한 결과는 호우 방향성을 고려한 유역 반응함수에 의해 유출모의 결과가 보다 개선될 수 있음을 나타낸다. 따라서 본 연구성과는 호우 방향성에 따른 유역 반응함수의 비선형성을 고려함으로써 유출모의의 불확실성을 줄이는데 기여할 수 있을 것으로 기대된다.

The management of existing concrete bridges has become a major social concern in many developed countries due to the large number of bridges exhibiting signs of significant deterioration. This problem has increased the demand for effective maintenance and renewal planning. In order to implement an appropriate management procedure for a structure, a wide array of corrective strategies must be evaluated with respect to not only the condition state of each defect but also safety, economy and sustainability. This paper describes a new performance evaluation system for existing concrete bridges. The system evaluates performance based on load carrying capability and durability from the results of a visual inspection and specification data, and describes the necessity of maintenance. It categorizes all girders and slabs as either unsafe, severe deterioration, moderate deterioration, mild deterioration, or safe. The technique employs an expert system with an appropriate knowledge base in the evaluation. A characteristic feature of the system is the use of neural networks to evaluate the performance and facilitate refinement of the knowledge base. The neural network proposed in the present study has the capability to prevent an inference process and knowledge base from becoming a black box. It is very important that the system is capable of detailing how the performance is calculated since the road network represents a huge investment. The effectiveness of the neural network and machine learning method is verified by comparing diagnostic results by bridge experts.

The idea of identification have become a subject of discussion ever since the time man started to contemplate on the meaning and value of his being. However, the concept of identity defined by theorists such as sociologists or cultural historians influence the consumption pattern of the major consumer group, in conjunction with the advent of the mass consuming age. The conflict and mutual realization among variable generations and residential areas of different. consumer levels profoundly affect the formation of the identity of the new generation and the role and experience of women. This series of transit is progressing more rapidly due to the characteristic situation of the expiration of a millenium. Advertising strives to control our interests and ideas on the products we choose to use and affects our identity by manipulating images of successful people. People tend to be influenced more significantly by the mass-culture than by people around them, such as family or friends, in rendering their self?identity; in which process, adopting the identity produced by mass-media and advertising. Such identity is conducted partly of the product identity and the stereotyped image suggested by mass-media. This study bears significance in the attempt to provide actual data and expand the realm of ideas and planning in future advertising through demonstrative analysis of self-identity creative in Korean TV advertising.
