Water has always played a significant role in the lives of people. In urbanised Rome, with its million people. sophisticated supply systems developed and then fled with the empire. only to be rediscovered later But it was the industrial Revolution commencing in the eighteenth century that ushered in major paradigm shifts In use and altitudes towards water. Rapid and concentrated urbanisation brought problems of expanded demands for drinking supplies, waste management and disease. The strategy of using water from local streams, springs and village wells collapsed under the onslaughts of rising urban demands and pollution due to poor waste disposal practices. Expanding travel (railways. and steamships) aided the spread of disease. In England. public health crises peaks, related to water-borne typhoid and the three major cholera outbreaks occurred in the late eighteenth and early nineteenth century respectively. Technological, engineering and institutional responses were successful in solving the public health problem. it is generally accepted that the putting of water into pipe networks both for a clean drinking supply, as well as using it as a transport medium for removal of human and other wastes, played a significant role in towering death rates due to waterborne diseases such as cholera and typhoid towards the end of the nineteenth century. Today, similar principles apply. A recent World Bank report Indicates that there can be upto 76％ reduction in illness when major water and sanitation improvements occur in developing countries. Water management, technology and thinking in Australia were relatively stable in the twentieth century up to the mid to late 1970s. Groundwater sources were investigated and developed for towns and agriculture. Dams were built, and pipe networks extended both for supply and waste water management. The management paradigms in Australia were essentially extensions of European strategies with the minor adaptions due to climate and hydrogeology. During the 1970s and 1980s in Australia, it was realised increasingly that a knowledge of groundwater and hydrogeological processes were critical to pollution prevention, the development of sound waste management and the problems of salinity. Many millions of dollars have been both saved and generated as a consequence. This is especially in relation to domestic waste management and the disposal of aluminium refinery waste in New South Wales. Major institutional changes in public sector water management are occurring in Australia. Upheveals and change have now reached ail states in Australia with various approaches being followed. Market thinking, corporatisation, privatisation, internationalisation, downsizing and environmental pressures are all playing their role in this paradigm shift. One casualty of this turmoil is the progressive erosion of the public sector skillbase and this may become a serious issue should a public health crisis occur such as a water borne disease. Such crises have arisen over recent times. A complete rethink of the urban water cycle is going on right now in Australia both at the State and Federal level. We are on the threshold of significant change in how we use and manage water, both as a supply and a waste transporter in Urban environments especially. Substantial replacement of the pipe system will be needed in 25 to 30 years time and this will cost billions of dollars. The competition for water between imgation needs and environmental requirements in Australia and overseas will continue to be an issue in rural areas. This will be especially heightened by the rising demand for irrigation produced food as the world's population grows. Rapid urbanisation and industrialisation in the emerging S.E Asian countries are currently producing considerable demands for water management skills and Infrastructure development. This trend e expected to grow. There are also severe water shortages in the Middle East to such an extent that wars may be fought over water issues. Environmental public health crises and shortages will help drive the trends.

Periodontal ligament (PDL) cells have been known as multipotential cells, and as playing an important rolesin periodontal regeneration. The PDL cells are composed of heterogeneous cell populations which have the capacity to differentiate into either cementoblasts or osteoblasts, depending on needs and conditions. Therefore, PDL cells have the capacity to produce mineralized nodules in vitro in mineralization medium which include ascorbic acid, ${\beta}$-glycerophosphate and dexamethasone. In spite of these well-known osteoblast like properties of PDL cells, very little is known about the molecules involved in the formation of the mineralized nodules in the PDL cells. In the present study, we analysed gene-expression profiles during the mineralization process of cultured PDL cells by means of a cDNA microarray consisting of 3063 genes. Nodules of mineralized matrix were strongly stained with alizarin red S on the PDL cells cultured in the media with mineralization supplements. Among 3,063 genes analyzed, 35 were up-regulated more than two-fold at one or more time points in cells that developed matrix mineralization nodules, and 38 were down-regulated to less than half their normal level of expression. In accord with the morphological change we observed, several genes related to calcium-related or mineral metabolism were induced in PDL cells during osteogenesis, such as IGF-II and IGFBP-2. Proteogycan 1, fibulin-5, keratin 5, ,${\beta}$-actin, ${\alpha}$-smooth muscle actin and capping protein, and cytoskeleton and extracellular matrix proteins were up-regulated during mineralization. Several genes encoding proteins related to apoptosis weredifferentially expressed in PDL cells cultured in the medium containing mineralization supplements. Dkk-I and Nip3, which are apoptosis-inducing agents, were up-regulated, and Btf and TAXlBP1, which have an anti-apoptosis activity, were down-regulated during mineralization. Also periostin and S100 calciumbinding protein A4 were down-regulated during mineralization.

Pleasure grounds, which were introduced during the Japanese colonial era, were places for organizing new amusement activities, and developed into a large-scale private spaces and a new type of public space at the same time. This study explores the scenery and accommodations of pleasure grounds and the changes of the amusement culture through the Wolmido Pleasure Grounds, which was a typical pleasure grounds of the time. At that time, Wolmido became a comprehensive amusement/entertainment place with many elements of both Western and Japanese pleasure grounds such as exotic buildings harmonized with trees, a beach, a seaside school, public playing field, and zoo constructed on the Island. Wolmido Pleasure Ground, which was connected with Kyungsung by Kyungin railroad during the Japanese colonial era, is a good example showing the process of the popularization and commercialization of the amusement culture. The process of popularization of amusement shows the spreading of the enjoyment of leisure time with amusement activities through appreciating the beautiful scenery of the pleasure grounds among various social classes. The caste system was broken and anyone could use the pleasure grounds by paying the fee, of which there were many kinds, so the distinction between genders and the different classes, such as the Chosun people and Japanese, regarding amusement in pleasure grounds disappeared gradually. Also, pleasure grounds were a place for Western hobby-sports activities and were the means to generalize collective and dynamic activities through summer school and various sport games. At the same time, there were places for deviation from the existing social norms when it was combined with entertainment facilities. The commercialization of amusement took place in the form of an artificial entertainment culture within an artificial environment. First, the scenery was artificially constructed and this scenery created the image of paradise such as 'captivating summer vacation spot' and 'water kingdom'. This was the result of the combined intentions of the colonial authority, the railroad company and the amusement corporation to produce economic profits and encourage development in the area. Second, an artificial spectacle was constructed using nature as the backdrop. Buildings of various styles created a modernized and exotic image when they were combined with each other. Artifacts such as breakwaters and arcades created new attractions for people that enabled them to view both nature and the crowds from a whole different perspective. Third, pleasure grounds contributed to the advent of passive users who would just follow the given use and instructions. In this way, one can find the prototype of popular entertainment places of today such as sightseeing complexes, amusement parks, and theme parks through the construction of amusement grounds as a place for providing dynamic activities.

This paper will investigate how animated practice can be a research form as practice-led research in an ethnography approach. This practice-led research will explore the issue of the construction of contemporary identities (based on the strange case of Dr. Jekyll and Mr. Hyde) and in particular, the Korean youth culture and identity, exemplified, for example, creation of 'avatars' in the virtual characters of animated online games such as Massively Multiplayer Online Role-playing Games (MMORPGs). In this proposed discussion, I will argue that the sudden period of change in contemporary Korea bears some resemblance to the Victorian era as explored in gothic fiction (e.g. Jekyll and Hyde). In this sense, my animation investigates the connection between the fictional Jekyll and Hyde and a real murder incident by a young Korean boy, which actually happened on the 16th November 2010, in SouthKorea.I will, therefore, construct this practice-led research to obtain the primary data consisted of online and offline practices in 'social ethnography'. These practices engage with specific Korean youth identity, comparing the 'avatar' with the real lives of participants. However, this paper will only focus on the (ethnographic) research process and strategy, using animated (visual) practices, rather than giving the meaning of the specific case of 'Korean-ness'. Eventually, I will explore the four different animated representations as it presents the distinctive animated realties or documentaries by online and offline practices. My intention is to visually interpret the issue of 'Korean-ness' within its socio-cultural context, adapting the convention and code of Jekyll and Hyde concept into an animated documentary in the 'virtual' world (auto-animated documentary by recording avatar interviews and online game footages) and the 'real' world (self-created animated documentary, based on real people and events).

It can be assumed that the reasons why the animation characters, 'Olaf (in Frozen Kingdom)' and 'Minions (in Super Bad)', etc., which were very successful in the merchandising market while having won the popularity better than the main characters are very popular even though such characters appeared only by playing a funny role while assisting the adventures of the main characters are not only because of their cute appearances but also because such characters have their own core features in their inner world as the transitional object-characters. Simply expressing, a 'Transitional Object' as a concept suggested by a child psychologist, 'Donald Winnicott', means a lovey doll or an imaginary friend which temporarily replaces an infant's mother during the procedure when the infant is mentally separated from its mother. However, in case that the theory of transitional objects was applied directly to many narrative content characters for doing a study, there must have been done some studies in advance for establishing some new criteria and indexes related to the transitional object-characters of such narrative contents. Accordingly, while thinking that the 'emotional relationship' between a growth-subject and a growth mediator must be dealt with as the most important content in order to define a transitional object-character in a narration clearly, this researcher established some emotional index for judging the propensities of a transitional object-character on the basis of such way of thinking. The index is composed of 4 kinds of emotional roles (quasi-family member, growth mediator, lovey doll, an imaginary friend), 6 kinds of emotional supports (hugging, protecting, accepting, giving the initiative, improving the relationship and mutual supervising) and 4 kinds of emotional impressions (impression by contacting, impression to protect and impression accepting an attack). In case that some main characters of a family feature animation, 'Inside Out', are analyzed while the index mentioned above is applied, it was found that 'Bing Bong' and 'Sadness' have a high propensity as a transitional object-character. Especially, it could be inversely inferred in which ways some good transitional object-characters can help the narrations on growth of a family feature animation by taking a look at the character, 'Sadness' that has the highest propensity as a transitional object-character. The transitional object-character, 'Sadness' assists the narration on growth internally and externally by helping the internal maturity of a growth-subject in a way of projecting the tasks for the internal maturity of a growth-subject while helping the growth-subject to be successfully externally in a way of providing the growth-subject with some kinds of facilitating emotion. As the results from this Study, since such kinds of emotional experiences provided by such transitional object-characters are displaced to not only the relevant growth-subjects but also the audience who are emphasized with such growth-subjects as they are, such transitional object-characters play a role of hidden benefactors who induce some immersion into the narrations and provide child and adult audience with various layers of emotional satisfaction.

Ischemia/reperfusion injury(I/RI) is the major cause of acute renal failure and delayed graft function(DGF) unavoidable in renal transplantation. Enormous studies on ischemia damage playing a role in activating graft rejection factors, such as T cells or macrophages, are being reported. Present study was performed to determine whether ischemia time would play an important role in activating rejection-related factors or not in rat models of I/RI. Male Sprague-Dawley rats were submitted to 30, 45, and 60 minutes of warm renal ischemia with nephrectomy or control animals underwent sham operation(unilateral nephrectomy). Renal function and survival rates were evaluated on day 0, 1, 2, 3, 5 and 7. Immunofluorescence staining of dendritic cells(DCs), natural killer(NK) cells, macrophages, B cells, CD4+ and CD8+ T cells were measured on day 1 and 7 after renal I/RI. Survival rates dropped below 50% after day 3 in 45 minutes ischemia. Histologic analysis of ischemic kidneys revealed a significant loss of tubular architecture and infiltration of inflammatory cells. DCs, NK cells, macrophages, CD4+ and CD8+ T cells were infiltrated from a day after I/RI depending on ischemia time. Antigen presenting cells(DCs, NK cells or macrophages) and even T cells were infiltrated 24 hours post-I/RI, which is at the time of acute tubular necrosis. During the regeneration phase, not only these cells increased but B cells also appeared in more than 45 minutes ischemia. The numbers of the innate and the adaptive immune cells increased depending on ischemia as well as reperfusion time. These changes of infiltrating cells resulting from each I/RI model show that ischemic time plays a role in activating rejection related immune factors and have consequences on progression of renal disease in transplanted and native kidneys.
