This study identified fashion consumers disposal behavior and analyzed the effects of consumers pursuing values in disposal, environmental awareness, and sustainable fashion consumption attitudes in regards to fashion disposal behavior. A survey questionnaire was developed and data were obtained from 460 consumers in their 20's to 50's in Korea who had experienced fashion disposal behaviors during last 12 months. As a result, there were four different fashion disposal behaviors such as economical, practical, and social disposal as well as hoarding behaviors. Consumers pursuing values in disposal affected fashion disposal behavior. Practical and economical values had positively impacted economical disposal and hoarding behaviors. While hedonic value had a negative impact on economical disposal behavior, it had a positive impact on social disposal behavior. Also, environmental-social values had positively impacted practical and social disposal behaviors. Fashion-related environmental knowledge had positively impacted economical and practical disposal behaviors and PCE affected social disposal behavior, while environmental concerns had a negative impact on economical disposal behavior. Consumers attitude toward used-fashion items, fashion recycling, and fashion innovativeness affected all of fashion disposal behaviors. Although hoarding behavior has been an under researched area, the finding implied that hoarding behavior was affected by consumer's pursuing value in disposal and sustainable consumption attitude. Also, environmental-social values and attitudes toward used-fashion items would induce practical disposal behavior such as reuse by alteration or reform. Consumers economical and hedonic values can promote donations or exchange/resale of unwanted fashion items, which can lead to sustainable consumption.

The purpose of this study is to analyze the issues concerning feminine forms of nouns which indicates occupations in French. In distinguishing the French masculine and feminine forms, many linguistic issues about feminizing occupational nouns became a hot issue among scholars. However, reasonably logical and effective methods to solve such issues are not suggested yet. The first part is focused on how the feminine forms were historically altered to investigate changing process of nouns representing jobs. Through this, we found that the occupational nouns' feminization is quite related to the social big changes, the woman's social condition and reality reflecting on languages periodically. We discussed the important factors deciding such changes, such as semantic, linguistic and sociolinguistic causes, in the second part of the study. And we mentioned issues which can be suggested in investigating grammatical rules of the feminine form of occupational nouns. The last part is on plans to learn the feminine form of occupations in an effective way. The language is being developed while it is closely related with social and cultural environment of people who use the languages. In this meaning, occupational nouns' feminization is a good example which can reflect chronological and social changes. Through the thesis, we know that it is not enough to provide explanation of changes of feminine occupational nouns about the woman's social roles' alteration. We just hope it can be at least a small help in doing more systematic and deeper analysis which can show the fact that languages reflect the phenomenon of social changes.

Courtyard is evolving from the conventional one element of a building far beyond into independent peremeter of urban architecture, of which function has been darmatically upgraded from embedded traditional air fluiding, nutural lighting system into where full fledged function can be experienced so much as your imagimation reaches taking major social responsibility such as intact offline social networking which links people from neighbors, inter / extra buiding openness which allow people can communicate among othewise between themselves and artificial natural environmental emelents supplier where people resort to relaxation and natural healing. Roles of courtyard has been by far streatched out into nearby natural healing space where people can shake off their unavoidable stresses from the modern life relaxing themselves looking at the sky otherwise observe natural surroundigns such as plants, flowers and waters. Thanks to hereonto mentioned its merits, Courtyard building is widely used and seen as a center of modern urban design in residence, public bilding and urban planned buildings. Courtyard biulding is nowadays boasting their morphological diversity brought out from lots of topological variation, type variants, cross section and inter relationship with the other neighboring spaces. Hence, hereby I have been studied how above mentioned three major peremeters of courtyard has been upgraded in modern architecture comparing the period from 1960 to 1990 and the period starting from 1991.

According to the rapid growth of the number of SNS(Social Networking Service) applications based on Android OS, the importance of its security is also raised. Especially, many applications using KaKaoTalk platform has been released in these days, and these are top ranked in the relative markets. However, security issues on SNS applications have not been resolved clearly. Therefore, it is crucial to provide means to cope with the security threats posed by code-segment modification in the development stage of Android OS based SNS applications. In this paper, we analyze the security threats by modifying SNS application code segments and suggest effective security techniques.

The activity to share personal daily life through social media is becoming more common. In this case, photographs as well as text are used a lot; it has been as easy as winking to clip others' photographs just as it's very easy to take and post pictures. If the picture is the photographic work protected by the copyright law, however, the clipping should be paid close attention. If you use others' photographic works without authorization, you infringe their copyright; if you post them on your social media such as blog, you infringe the right of reproduction, interactive transmission and exhibition. Even though the clipping is permitted, if you'd like to use the photographic works for a profit-making purpose, you should get additional authorization. Others' photographic works are occasionally altered and used for the purpose of avoiding the argument in relation to the infringement of copyright; this act means that it's the infringement of the right of reproduction, the right to preserve the integrity and the right of the production of derivative works for degrees of alteration. We can download others' photographic works with a few mouse clicks thanks to the technology of capturing the screen; we have to recognize that all the acts technically possible are not always legal.

Previous studies have shown disrupted synaptic plasticity and neural activity in depression. Such alteration is strongly associated with disrupted synaptic structures. Chronic stress has been known to induce changes in dendritic structure in the basolateral amygdala (BLA) and medial prefrontal cortex (mPFC), but antidepressant effect on structure of these brain areas has been unclear. Here, the effects of imipramine on dendritic spine density and morphology in BLA and mPFC subregions of stressed mice were examined. Chronic restraint stress caused depressive-like behaviors such as enhanced social avoidance and despair level coincident with differential changes in dendritic spine structure. Chronic stress enhanced dendritic spine density in the lateral nucleus of BLA with no significant change in the basal nucleus of BLA, and altered the proportion of stubby or mushroom spines in both subregions. Conversely, in the apical and basal mPFC, chronic stress caused a significant reduction in spine density. The proportion of stubby or mushroom spines in these subregions overall reduced while the proportion of thin spines increased after repeated stress. Interestingly, most of these structural alterations by chronic stress were reversed by imipramine. In addition, structural changes caused by stress and blocking the changes by imipramine were corelated well with altered activation and expression of synaptic plasticity-promoting molecules such as phospho-CREB, phospho-CAMKII, and PSD-95. Collectively, our data suggest that imipramine modulates stress-induced changes in synaptic structure and synaptic plasticity-promoting molecules in a coordinated manner although structural and molecular alterations induced by stress are distinct in the BLA and mPFC.

Forest Canopy Density is a dynamic process mediated by various natural and anthropogenic factors. It can be changed over time and locations in the same forest type and landscape. However, human dimensions are considered as the primary force of landscape change and subsequent forest canopy loss in tropical regions of the world. Many studies have been indicated that roads have a far greater impact on forests than simply allowing access for human use. Similarly, rivers have been used as means of transportation, hence illegal logging and felling further deplete forest canopy density. The main objective of this study was to investigate the spatio-temporal dynamic alterations of Forest Canopy Density (FCD) across with site associated factors such as biophysical, physical and human interferences in tropical region of Nepal from 1988 to 2001. Landsat TM and ETM+ of 1988 and 2001 were used to assess the spatial and temporal dynamic alterations of FCD. This analysis revealed that distance to human settlements at P=<0.01, rivers, human interferences (path and fire) and species composition had a statistically significance at P=<0.05 level. However, other factors did not show any significant relation. So, we concluded that understanding of dynamic alterations of FCD with respect to factors was quite complex phenomena. Other surrounding environment could also playa significant role. A comprehensive analysis could be required to understand such complexities. Therefore, additional factors such as climatic, biophysical, social, and institutional with respect to spatio-temporal variability should be considered for the better understanding of canopy dynamic.

To improve esthetics and gain beautiful smile, the maxillary anterior dentition is crucial. Through alteration of height, arrangement or color of the maxillary incisor, we can rehabilitate the esthetic smile. The perception of dental esthetics is highly subjective. Personal perceptions or judgement of dental esthetics is highly related with each individual's experience and social and cultural environment. However, there have been many efforts to establish the criteria for generally accepted esthetic norm, in order to increase the predictability of restorative treatment. For maxillary anterior restoration, not only a single tooth, but also the compositions around tooth such as facial form, lips and gum and their relationships have to be considered to create harmonious smile. It can be determined as esthetic restorations when in consonance with facial form and structures that frame the restorations. In this review article, several guidelines that are generally accepted and useful to assess the esthetics and communicate with patients and technicians will be discussed.

Cognitive impairment associated with childhood-onset epilepsy is an important consequence in the developing brain owing to its negative effects on neurodevelopmental and social outcomes. While the cause of cognitive impairment in epilepsy appears to be multifactorial, epilepsy-related factors such as type of epilepsy and underlying etiology, age at onset, frequency of seizures, duration of epilepsy, and its treatment are considered important. In recent studies, antecedent cognitive impairment before the first recognized seizure and microstructural and functional alteration of the brain at onset of epilepsy suggest the presence of a common neurobiological mechanism between epilepsy and cognitive comorbidity. However, the overall impact of cognitive comorbidity in children with epilepsy and the independent contribution of each of these factors to cognitive impairment have not been clearly delineated. This review article focuses on the significant contributors to cognitive impairment in children with epilepsy.

Objectives : Alteration of hippocampus was demonstrated in the maternal social separation(MSS) pups, separated from dams on postnatal day(pnd) 14 and placed alone. Therefore, to understand the molecular events involved in the MSS, we have initiated a search for gene profiles that are up or down-regulated in the hippocampus of MSS pups. Methods : Analysis of cDNA microarray was performed by using total RNA extracted from the hippocampus of control and MSS pups on pnd 17. Also, passive-avoidance test was demonstrated on pnd 35. Results : Up-regulation of Nedd4a was observed in the hippocampus of MSS pups. Also, MSS rats showed less elongation of latency in passive avoidance test. Conclusion : We suggest that environmental effects of MSS may be altered the neural and/or glial differentiation and synapse formation-related genes which may lead cognitive alterations in MSS rats.
