  • Emergence of advanced materials has been realized by the great demands for sophisticated state devices in high technology industry. It is the ear of speedy evolution of science and technology, in particular, materials processing technology, which enables us to synthesize any materials with respect to its purity and its perfection of crystal structure and shape (form) that have, heretofore not been available. The availability of ultra pure, fine raw materials, single crystals and thick/thin film materials has been largely responsible for such startling progresses that have been made in the realization of unforeseen, functional devices for high technology industry. Of the functional devices such as passive as active devices, non-silicon devices are mostly passive. Piezoelectric, electro-optic, magneto-optic devices, etc. are some of the examples. In this paper, magneto-optic materials for Faraday device, which is little known, are reviewed including its processing toward practical applications.

  • This study aims to solve the entangled loop between demographic transition (DT) and economic growth by analyzing cross-country data. We undertake a national-level group analysis to verify the compressed transition of demographic variables over time. Assuming that the LA (latecomer advantage) on DT over time exists, we verify that the DT of the latecomer is compressed by providing a formal proof of LA on DT over income. As a DT has the double-kinked functions of income, we check them in multiple aspects: early maturation, leftward threshold, and steeper descent under a contour map and econometric methods. We find that the developing countries (the latecomer) have speedy DT (CDT, compressed DT) as well as speedy income such that DT of the latecomers starts at lower levels of income, lasts for a shorter period, and finishes at the earlier stage of economic development compared to that of developed countries (the early mover). To check the balance of DT, we classify countries into four groups of DT---balanced, slow, unilateral, and rapid transition countries. We identify that the main causes of rapid transition are due to the strong family planning programs of the government. Finally, we check the effect of latecomer's CDT on economic growth inversely: we undertake the simulation of the CDT effect on economic growth and the aging process for the latecomer. A worrying result is that the CDT of the latecomer shows a sharp upturn of the working-age population, followed by a sharp downturn in a short period. Compared to early-mover countries, the latecomer countries cannot buy more time to accommodate the workable population for the period of demographic bonus and prepare their aging societies for demographic onus. Thus, we conclude that CDT is not necessarily advantageous to developing countries. These outcomes of the latecomer's CDT can be re-interpreted as follows. Developing countries need power sources to pump up economic development, such as the following production factors: labor, physical and financial capital, and economic systems. As for labor, the properties of early maturation and leftward thresholds on DTs of the latecomer mean that demographic movement occurs at an unusually early stage of economic development; this is similar to a plane that leaks fuel before or just before take-off, with the result that it no longer flies higher or farther. What is worse, the property of steeper descent represents the falling speed of a plane so that it cannot be sustained at higher levels, and then plummets to all-time lows.

  • This study investigated the effects of temperature on the shoot growth and flowering of potted kumquat [Fortunella margarita ( Lour.) Swingle] trees grown in subtropical conditions of I-Lan County in Taiwan. Temperature treatments included T 25-32, T 17-25, T 22, and T 18. The T 25-32 treatment trees were to the day/night temperatures of $25/18^{\circ}C$ for 2 weeks, followed by 28 weeks at $32/25^{\circ}C$. T 17-25 was exposed for 4 weeks to $17/10^{\circ}C$ followed by 26 weeks at $25/18^{\circ}C$. T 22 and T 18 were exposed at $22/18^{\circ}C$ and $18/13^{\circ}C$, respectively, for the entire duration of the experiment. Control trees were placed in a plastic greenhouse under conditions similar to the natural environment. The kumquat trees exposed to high-temperature environment of $32/25^{\circ}C$ showed more frequent and speedy sprouting of new buds, but induced the earlier termination of shoot elongation growth, resulting in decreased vegetative growth. The temperature treatments lower than $22^{\circ}C$ suppressed the new shoot production but increased the shoot growth period, resulting in increased shoot length and diameter. Temperatures higher than $25/18^{\circ}C$ readily induced flowering, with flowering being advanced under the higher temperature conditions such as $32/25^{\circ}C$. However, flowering was substantially inhibited under temperature conditions lower than $22/18^{\circ}C$, indicating the negative role of relatively lower temperatures on flowering of kumquat trees.

  • Through the courses of industrialization, speedy growth and pluralism. The problems about the environment- friendly structures have become very important problem. Especially, it is getting highly appear to the expectation about the environment friendly buildings in Kangwon-do where has greacefully clean environment. The guide line for Kangwon-do can be arranged to the following through the varity analysis, outside enviroment, color, construction materials, outside design etc the guide line for Kangwon-do can be arranged as to the followings. It appears to be suitable to country houses in kangwon-do that is made of timber or red-bricks with green half circled roof and give a sense of warmth and soft. but the coastal area village is appeared wave style roof with orange color and surrounded by natural building stones or a line- plastered wall making complicated.

  • The world is changing so rapidly and being globalized and competitive. Also, food service companies in Korea have been making a speedy growth. In order that food service companies ran take long-term viability, they should introduce the market-orientation concept. Because market-orientation requires to investigate the factors of ever-diversified market environment on a regular basis, they can build up more detailed, practical and differentiated strategies than before. Thus, this study aimed to establish that the strategy of competitive edges based on the concepts could yield excellent marketing performance.

  • In Korea, by the reason of the rapid growth of internet users and the speedy development of ITC, the sales of cyber malls have grown to be ₩10.68 trillion. Over the past several years, trust and commitment have been viewed key concept and mediated variables in relationship marketing. From 2000s, trust and commitment have been studied in cyber shopping environment. Most of studies are the relationship of trust and loyalty or unidimensional commitment and loyalty. The purpose of our study focused the mediated effects of multidimensional commitment on relationship between trust and loyalty. Trust, affective commitment, and continuous commitment affected positive effects on loyalty. And trust also affected positive effect on affective commitment. Trust didn't affect positive effect on continuous directly. However, There was indirect effect of between trust and continuous commitment via affective commitment.

  • 본 연구는 예초 직후에 prohexadione-calcium을 처리하여 잔디의 생장 상태를 조사하였다. 한국잔디로 조성된 잔디밭이나 골프장을 효과적으로 관리하기 위하여 한국잔디의 예초 직후 prohexadionecalcium의 농도를 달리하여 엽면 처리한 결과 무처리와 비교하여 잎의 생장이 현저히 감소되는 것으로 나타났으며 prohexadione-calcium의 1회 처리로도 그 효과가 처리후 50일까지 잎의 생장이 46~50%정도 감소되는 것으로 나타났고, 엽폭도 처리농도가 높을수록 무처리에 비하여 좁아졌다. Prohexadionecalcium 처리후 건물중의 변화를 보면 처리후 2주후 부터 무처리에 비하여 현저하게 감소하는 것으로 나타났는데, 처리 농도가 높을수록 건물중이 작았으며 처리 40일까지도 건물중의 증가가 무처리에 비하여 유의하게 감소하는 것으로 나타났다. 또한 엽색도는 prohexadione-calcium의 처리구가 무처리구에 비하여 높았다.
