The knowledge of the specialized fields has been changed rapidly in the both side of quantity and quality. A hyper media as a knowledge based system is so fixed in the linked media in mutual that we couldn't tell it information provision with the view of users. In this paper, we propose the way of offering intellectual and flexible information which is the same with demand in the side of user, selecting, searching and composing the hypertext at the point of user's view through the design of knowledge media system. Three concepts are used in order to challenge the knowledge media system : special document, agent system and ontology. The special document is a ensure that its activities are coordinated with those of the others within the community, providing a uniform control mechanism. Finally, ontology is a language for exchanging knowledgement, which is a message exchanged among agents to ensure the proper interaction among them. The combination of these three concepts is used to design the prototype of knowledge media system.

With the diversified development of modern art, the application of mixed media in painting has become increasingly prominent, which not only provides artistic creators with new creative ideas, but also magnifies the creators' emotions and re endows the media with meaning and value. This paper systematically introduces the definition, features and connotation of mixed media painting, and expounds three aspects of the aesthetic function of multimedia in oil painting creation, the embodiment of painting individuality, and the combination and application of materials and technique to demonstrate that mixed media presents different understanding and expression in Chinese oil painting, no longer constrained by traditional oil painting materials, which promotes more development possibilities of the art expression form of Chinese oil painting, enhances its international influence, and bring new vitality to the creation and development of Chinese oil painting.

This study compares the performance of the filters with various media in pretreatment of seawater desalination by reverse osmosis. For this purpose, Masan bay seawater is used as raw water. The filter performance is evaluated by the filtrate quality and the head loss development. Five media is selected in this study: anthracite, $Filtralite^{(R)}$, sand, Pumice, $AFM^{(R)}$. These media are used in combination for dual media filter and alone for mono media filter. The comparison results show that NC0.8-1.6 is the best $Filtralite^{(R)}$. The dual media filter of NC0.8-1.6 and sand outperformed other filters in particle removal. The dual media filter of anthracite and sand showed good performance in organic removal. The mono media filter of Pumice produced the similar filtrate quality as the mono media filter of sand although the effective size of Pumice is considerably greater than that of sand. Due to big size, head loss development is maintained slow in the filtration of Pumice.

Studies were made to optimize the media composition and cultural condition for mycelial growth of ear mushroom(Auricularia auricula). Sawdust spawn of media composition for optimal growth were found to be quercus sawdust combination of 20% rice bran and poplar sawdust combination of 10% wheat bran were the best of the optimal combination. The optimal condition of the most suitable inoculation amount showed that quercus spawn and poplar spawn were 15g, 25g, respectively.

Studies were made to optimize the media composition in bag culture and conducted to determine the possibility of artificial cultivation of Auricularia auricula. Sawdust spawn of media composition for optimal growth were found to be oak-sawdust 80%combination of 20% popla-sawdust were the best of the optimal combination. And optimal substrate combination were found to be cotton-seed meal combination of 10% wheat bran 5% mixed were the best of combination. The duration of spawn run period and primordial formation period on bag(1.2 kg) were 50 days and 7 days, respectively. The weight of fruiting body and the yield(100ea, 1.2 kg) of fresh fruit-body were 24 g and 45,000 g, respectively.

A hybrid permeable reactive barriers(hybrid PRBs) composed of Fe(II) PRB, biological PRB and sorptive PRB was investigated to treat groundwater with multiple contaminations. We performed batch, column and pilot tests to determine removal rates and design parameters of each PRB media, and operated two hybrid PRB systems with pilot-scale barriers in series. The pilot test of the hybrid PRB system with the combination of Fe(II), biological media and black shale showed multiple contaminations could be removed in ground water. Nitrate could be treated below 20 mg/L and Cr(VI) was treated down to 0.05 mg/L. TCE was degraded below 0.001 mg/L in system. The hybrid PRB system with a proper combination of PRBs could remediate ground water with multiple contaminations.

The goal of the present study is to explore IM interruption by relating it to media choices and purposes of IM use in the workplace. Two major media choice concepts were: media richness and social influence; while four purposes of IM use were: organization work, knowledge work, socializing, and boundary spanning activities. Data (N = 283) were collected via a combination of convenience and snowball sampling of "computer-using workers" in Taiwan, based on the Standard Occupational Classification system published by the Taiwan government. Results indicated that media choice works better than purpose of IM use to explain IM interruption. Among them, social influence was the best predictor to IM interruption in the workplace. In addition, instant feedback and personalization provided by IM, and IM usage for the purposes of knowledge work and socializing, also relate to IM interruption in the workplace.

The purpose of this study was to examine media influence on college students' thoughts and explore determinants of the media influence. Between September 7, 2013, and September 12, 2013, a questionnaire survey was administered to students at university-A and total 328 useable responses were collected. Findings are as follows: (1) Houses in TV drama had a strong influence on college students' future housing preferences but had a relatively weak influence on housing satisfaction and concrete housing expectations; (2) students perceived that houses in TV dramas did not reflect reality well; (3) females and/or relatively younger respondents tended to perceive a stronger influence of media on their thoughts and expectation on housing; (4) respondents who had a stronger desire to imitate lifestyle of TV drama characters and a stronger perception that houses in TV drama reflected reality well, and the respondents whose consumption preferences were more easily influenced by media were found to perceive media influence on their housing expectation stronger; and (5) to see regression analysis results, a linear combination of desire to imitate lifestyle of TV drama characters, perception of reality reflection of houses in TV dramas, gender, perceived media influences on clothes and accessories, and electronics preferences was found to be able to explain 46.4% of variance in media influence on housing expectations.
