Today, there is increasing recognition of the importance of urban regeneration for better public places. Urban parks as a public area play an important role in harnessing its positive impact on people's well-being: where the standards and funding of/for the parks are getting worse. There is however less a focus on policy approach to park regeneration in the country. Neverthless, a few UK's cases of such innovative park management(PM) has shown successful park regeneration based on policy support. Therefore, the aim of this research is to draw policy implications by exploring a case of successful park regeneration. To address the aim, this research conducts an in-depth case study of 'Manor Fields Park, UK', digging into its PM structure and PM body 'Green Estate Ltd' in relation to relevant policy. The data is mainly collected by interviews including a group interview. The analytical framework 'Place-keeping(PK)' and its six dimensions are employed to determine the characteristics of MFP's PM structure. Resultingly, there is a significant shift in the approach to PM which stresses the principle of long-term and self-sustaining structure led by a non-profit organisation and strong impacts of policy. In this context, PK highlights significant drivers for parks regeneration particularly in terms of policy implications: 1)providing policy support to encourage non-profit organisations in PM, 2)extending community involvement in decision-making processes, 3)promoting income generation by community groups, 4)shifting public awareness of shared responsibility for PM, 5)completing regular park maintenance assessment by community groups, and 6)delivering low-maintenance approaches to PM. To support these implications, PM structure for successful parks regeneration does meet a holistic and multi-dimensional approach of place-keeping underlined by understanding policy contexts and rethinking current status quo of PM. Addressing these implications will shed light on urban PM in an era of austerity and ultimately contribute to improving people's well-being.

These days, the application of electronic power transformers (EPTs) is expanding in place of ordinary power transformers. These transformers can transmit power via three or four wire converters. Their dynamic performance is extremely important, due to their complex structure. In this paper, a new method is proposed for improving the dynamic performance of distribution electronic power transformers (DEPT) by using sliding mode control (SMC). Hence, to express the dynamic characteristics of a system, different factors such as the voltage unbalance, voltage sag, voltage harmonics and voltage flicker in the system primary side are considered. The four controlling aims of the improvement in dynamic performance include: 1) maintaining the input currents so that they are in sinusoidal form and in phase with the input voltages so they have a unity power factor, 2) keeping the dc-link voltage within the reference amount, 3) keeping the output voltages at a fixed amount and 4) keeping the output voltages in sinusoidal and symmetrical forms. Simulation results indicate the potential and capability of the proposed method in improving DEPT behavior.

Vacuum cooling were carried out for freshness keeping of shiitake mushroom. Shiitake mushroom was cooled within 30 minutes from $20.5^{\circ}C$ to $0.5^{\circ}C$ by vacuum cooling, and then temperature drop of $6.6^{\circ}C$ per weight loss of 1% was taken place during precooling. Weight loss, surface discoloration and softening were reduced by precooling. Judging from organoleptic properties such as cap opening, discoloration, texture and off-flavor, shelf-life of precooled mushroom was lengthed by 20% than that of non-treated mushrooms. Considering effect of packing material on freshness of shiitake mushroom after precooling, weight retention, hardness and organoleptic properties of mushroom packed with PVC wrap were superior to those packed in carton box.

This study focused on the one and only temple of on the coastline of the West Sea, Kimje's Manghae Temple and Mt. Jinbong. The purpose of this study was to research the unique sense of place of the area by researching the location and view that clearly shapes the identity of the landscape. The following are the results. 1. The cultural landscape of Manghae Temple and the natural landscape of Mt. Jinbong have characteristics which take in the coastline and skyline, respectively. Specifically, from the existential vertical-horizontal images of "sky - land - Mt. Jinbong" and "moon - cloud - sea", an ascending reflection of the landscape surroundings can be found. 2. The "Sea - Manghae temple - Mt. Jinbong - sky" is the representation of the moderate 'inside-space' which belongs to the particular landscape area and which also shows the topophilia to Manghae Temple. Through this kind of interpretation, the sense of place of Manghae Temple and Mt. Jinbong reveals an intra-structure of an Imaging Landscape implying harmony and moderation, which is a unified organization of the surrounding phenomena(Temple and Mountain) and the essence (the doctrine of Buddhism) that matches Jin-muk's asceticism and lifestyle. 3. While the cultural landscape of Manghae Temple has a strong religious reference, the natural landscape Mt. Jinbong emphasizes the geography of the landscape. In other words, the motivating factor of Manghae Temple is a metaphorical sense of place such as through the "prospect of the sea" or "the Western Sea Paradise" and Mt. Jinbong, the landmark of the Kimje-Mankyung Plains and the focal point of the West Sea sunset, is highlighted as a simile for this sense of place. 4. Keeping this sense of place and territory respectively and showing the. bond with the sense of place which develops rhythmically and continuously, Manghae Temple and Mt. Jinbong are sublimated into a unified intra-structure, which reflects the Imaging landscape characteristics of "Mt. Jinbong, a focal point of the Mankyung Plains facing the West Sea" and "Manghae Temple, looking out to sea".

Central government and local self-governing bodies are actively promoting bicycle-riding as a solution for transportation, environment, energy and health. They put lot of efforts in the practice of bicycle-related policies such as building bicycle-related infrastructure and creating task force team to improve the bicycle-related systems. However, there is no substantive improvement in the city rail operation agencies regarding the bicycle-related facilities and operation. The expansion of bicycle-related infrastructure in city rail stations is urgently required considering the increase in demands from the bicycle-riders for the facility and bicycle-related service improvement. Accordingly, this study suggests a bicycle-riding vitalization plan linking the city rail and bicycle by providing with a bicycle custody place in the city rail stations which will have comprehensive convenience facilities including the safe-keeping facility for bicycles.

Objectives : This study is designed to survey of proper practice of toothbrushing place in elementary school, middle school and high school in some part of Gyeonggi-Do, and will be utilized for toothbrushing place management. Methods : It was randomly selected, 8 elementary schools, 6 middle school and 6 high school in Gyeonggi-do, surveyed whole students. Survey duration was from May 11th to May 20th in 2011. The surveying paper was consisted of questions of general characteristics, right practice of toothbrushing and toothbrushing after lunch etc. It was done under teacher's control. The Data was analyzed with SPSSWIN 18.0. Results : Students did toothbrushing 2 times/day. It wasn't done by Elementary students of 56.3%, middle school students of 68.5%, high school students of 39.3%. It was dominant reason for no brushing that Carrying toothbrush and toothpaste was annoying. When students washed their hands and rinsed their mouth, they used toilet facuet in over than 90% schools. Satisfaction ratio was very low in elementary, middle, high schools. 60% of students wanted to get mouth rinsing place in each school or separately nearby toilet. Conclusions : It was thought by 60% students of elementary, middle, high school that toothbrushing after meals was most important activity. But It was not well done after lunch. When whole student did toothbrushing together, they couldn't use mouthrinsing place comfortablely. There were no keeping places for toothbrushes. So more attention should be payed to make plenty mouthrinsing places and manage them well.

Keeping in mind the hybridity and plurality of Southern Literature, this paper discusses the traits of Southern literature in Jayne Ann Phillips's first novel, Machine Dream. The novel's frequent use of memory and oral reconstruction of a family history accompanied by the feeling of loss in the process of depicting the South's past typically signifies "The Southern" which reminds us of the works of William Faulkner, Katherine Ann Porter, and Eudora Welty. Nevertheless, Phillips's South is more fragmented and her narrative is more evasive and varied than any of her Southern predecessors. The South of the twentieth century from the period of Depression until 1972 is reconstructed differently depending on memories and desires of the four members of Hampson family in this novel, either as a place of nostalgia or as the place of trauma or as the place to survive only in memory. The oxymoronic title of the novel, "machine dreams" signifies that dream and memory of the South cannot remain independent in its epistemological entity but exist as a mixture of materiality of every day life in the modern South. The hybridity of this dream and of the South is what defines itself as Southern. Yet Phillips retains feeling of loss and lament enough to create a modern Southern novel rooted in Southern Literature. Thus, the title itself works an antinomic signifier of both the presence and absence of the dream of the South and of Southern Literature.
