  • In the flotation system for deinking process, the ink partcles musl collidc with the air bubbles for adhesion The probability of bubble-particle collision is largely dependent on the hydrodynamic conditions The main reason for the very small ink particles not to be able to float easily may be tound in the hydrodynamic effects, which make small ink particlcs move following the slreamlines around the bubbles rather than achually collide with bubbles. Also. the low floatabdily of the large and heavy ink particles is due to the gravity force and viscous drag which affect uprising molinn of particles through the liquid. Therefore, it is vely important to control not only the surface chemical conditions but the hydrodynamic conditions in practical floialion system

  • China's population and family planning program has heen successful. Women's fertility as measured by total fertility rate (TFR) has declined from 5.8 in 1970 to 2.3 in 1990, accordingly the annual crude birth rate(CBR) has declined from 34 per thousand in 1970 to 21 per thousand in 1989, and the annual natural growth rate from 2.6 percent in 1970 to 1.4 percent in 1989 (Coale and Chen, 1987; SSB, 1991; Gu, 1994). While this is indeed an astonishing achievement for a developing country to have its fertility down to replacement within a short period, some new issues emerging along with the rapid fertility decline require careful considerations. One of them is the uprising of the sex ratio at birth in China. The 1990 population census reported the sex ratio at birth in China of 113.8 in 1989, which is ohviously much higher than the acceptable level of normal ratio around 106. It has received since then a lot of tention in China and abroad, among demographic professionals and governmental agencies alike (Hull, 1990; Johansson and Nygren, 1991; Xuand Guo, 1991; Tu, 1993; Gu and Xu, 1994; among others). Based on the available demographic data and research results this paper will first have a review of the patterns and trends of sex ratio at birth in China, then turn to the immediate causes of abnormal sex ratio at birth and the determinants of the son preference, followed with a conceptual framework for understanding of the phenomenon, and finally the policy implications and recommendations will be discussed.

  • Along with the uprising of sustainability issues in the field of business and management, firms increasingly strategize and mobilize resources towards sustainability related activities and processes much more than ever. Together with this phenomenon, the concept of corporate sustainability has been noticed much more by scholars and practitioners from diverse fields. However, differently with an expectation, it is undoubted that there is a small controversy when we treat the issues related to its definition, antecedents, consequences, processes and so on. Based on this kind of understanding, this study tries to suggest and advance a new approach to the corporate sustainability based on the premises of social capital theory for social relations, which explains the role of institutions, and norms that shape firms 'social interactions. Main argument is that firm's voluntary, progressive, and proactive activities for sustainability issues can be understood as the firm's social capital building processes. Though there are a little existing study dealing with this issue, this study has a difference with them by proposing social capital building issues based on firm's real activities. Finally, case analyses based on a new approach are suggested and the theoretical considerations with some limitations are explained.

  • Objectives : Acne, one of the most common disorders in dermatology clinic, is a chronic inflammatory disease which has the symptoms of comedones, papules, pustules, cysts, nodules and scars mainly on the face. Although some of pathologic findings are suggested, but the exact causes and mechanisms are not yet known in Western Medicine. Hwangryeonhaedok-Tang(HRHDT) is an antiinflammatory, antipyretic and detoxifying herb decoction. In this report, we would like to share our experience of acne treatment with HRHDT. Methods : We had treated several patients with acne, facial flushing and uprising febrile sensation on face using oral administration and external application of HRHDT. HRHDT is basically made up with Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus. In this trial, several other herbs were added according to the individual patient's accompanying symptoms. After the decoction of herbs in amount for 10 days, $Yogourmet^{(R)}$ Kefir Starter 10 g was added to the herbal solution that was then fermented in an incubator at $25^{\circ}C$ for 72 hours, and divided into 30 doses. Results : Photographies were taken before and after the treatment. The severities of acne were evaluated with these photos according to the Korean Acne Grading System(KAGS). As results, we observed dramatic clinical improvements and the decreases of KAGS grades after the average treatment period of 8 weeks. The medication was orally administered 3 times a day and the external treatment was applied average twice a week during the whole treatment period. Conclusions : From these results, HRHDT may be considered as a good prescription for the febrile and toxic type of acne patients.

  • Many studies states that improperly uprising of infrastructure may cause leading the forest degradation and canopy reduction in many tropical forest of Asian countries. Other studies revealed that habitat destruction and fragmentation, edge effects, exotic species invasions, pollution are provoked by roads. Similarly, environmental effects of road construction in forests are problematic. Similarly, many researches have been indicated that roads have a far greater impact on forests than simply allowing greater access for human use. Moreover, people using river as means of transportation hence illegal logging and felling cause canopy depletion in many countries. Therefore, it is important to comprehend the study about spatial relation of road, river and suburb followed by temporal change of forest canopy phenomena. This study also tried to examine the effect of road, river and suburb in forest canopy density change of Terai forest of Nepal from you 1988 to 2001. So, Landsat TM88, 92 and 001 and FCD (Forest Canopy Density) mapper were used to perform the spatial .elation of canopy density change. ILWIS (Integrated Land and Water Information System) which is GIS software and compatible with remote sensing data was used to execute analysis and visualize the results. Study found that influence of distance to suburb and river had statistically significance influenced in canopy change. Though road also influenced canopy density much but didn't show a statistical relation. It can be concluded from this research that understanding of spatial relation of factors respect with canopy change is quite complex phenomena unless detail analysis of surrounding environment. Hence, it is better to carry out comprehensive analysis with other additional factors such as biophysical, anthropogenic, social, and institutional factors for proper approach of their effect on canopy change.

  • This study is to reconsider the symbolic potential of the costume by investigating the role of cloth in Indian culture, noting the fact that Indians wore hand-woven cloth and adopted a flag with the spinning wheel in the center as part of their nationalistic programs for independence. The results are as follows; The Indian cotton industry had held the fist position in the world and spinning and weaving had been an Indian national industry until the early part of the 19th century. As for the Indian cotton industry under the rule of Britain, Indian was reduced to being a colony producing raw materials and a market of cheap British finished goods, and eventually fell into anarchy with economic poverty of the general public and peasants'uprising mixed with the complaint of the intellectuals. The Indian National Movement started as a resort to escape the British rule because of continuous poverty and social exhaustion, and its pivot was Gandhi. Gandhi launched a revolutionary noncooperation movement in Indian society with diverse races, religions and castes, and developed nation-wide campaigns such as Boycott, Swadeshi, the encouragement of spinning wheels, etc. Gandhi urged that Indians' weak identity and poverty were caused by the dissolution of their native craft and that the Indians should wear Indian products for economic independence. Accordingly, leaders of Indian National Congress regarded a spinning wheel as an economic necessity and national symbol, and approved manual spinning and weaving as part of their nationalistic programs in order to drew the general public to the nationalistic movement in 1920. They also decided that all Congressmen should wear hand-woven cloth, Khadi, and adopted spinning wheels as the logo type of Indian National Congress. Khadi, Indian national cloth, was a symbol of national unification, freedom and equality, and also a means of economic self-sufficiency, Swadeshi, and eventually led India to autonomy, Swaraji. Therefore, it can be concluded that the cloth converted Indias economic and political identity.
