Background: Storage reservoirs of radioactive waste could be the source of atmospheric pollution due to the efflux of aqueous aerosol from their water areas. The main mechanism of formation of aqueous aerosols is the collapse of gas bubbles at the water surface. In this paper, we discuss the potential influence of biological factors on gas ebullition in the water areas of the radioactively contaminated industrial reservoirs R-9 (Lake Karachay) and R-4 (Metlinsky pond) of the Mayak PA. The emission of the released non-dissolved gases captured with gas traps in reservoir R-9 was (88-290) ml/m² per day (2015) and in reservoir R-4 (270-460) ml/m² per day (2016). The analysis of gas composition in reservoir R-4 (60% methane, 35% nitrogen, 2.4% oxygen, 1.5% carbon dioxide) confirms their biological origin. It is associated with the processes of organic matter destruction in bottom sediments. The major source of organic matter in bottom sediments is the dying phytoplankton developing in these reservoirs. Conclusion: The obtained results form the basis to set a task to quantify the relationship between the phytoplankton development, gases ebullition and radioactive atmosphere contamination.

The fashion advertisement is communication method between clothing and consumer. The development of mass communication accelerated that In modern society Post-modernism advertisement is a specialized and separated from so it confuses the consumers who are used in traditional AD. The peculiarities (non-form, destruction of description, compound of genre, mixing of reality and fiction) are more reflected in fashion advertisement. The sample consisted of 425 mail and female and the results were analyzed using frequency and percentage calculation Close tabs T-Test Oneway Anova Factor analysis Chi-square Test, Regression, Correlation Analysis. The result of this study were as follows: The post-modernism fashion ad is the separated and reflected from for young age's favorite. By the factor analysis of consumer response in each 5 emotional factors proved to be valid ones(fine, negative, sexual, stimulative, constructive aspects.) The fine and negative aspects of the factors are very concerned with the consumer's favorite attitude of fashion ad. There is no significant difference in age job but sex has a significant difference. In according to the method of the ad expression consumer's acceptance is difference in sex. There were no significant concern with excess effects and purchase intend in fashion advertisement.

A survey was conducted to determine the prevalance of infectious pancreatic necrosis virus (IPNV) on fish farms in Korea and the epidemiology of IPNV infection in the farmed rainbow trout. In total, 43 pools of rainbow trout with apparent signs of viral infection from five provinces were obtained and analyzed. Evident cytopathic effects, including karyopycnosis and cell destruction, were observed in CHSE (chinook samlmon embyro)-214 cells infected with the virus isolates. Of these, ten viral isolates were assumed to be IPNV based on biophysical properties. RNA analysis revealed that the isolates contained two-segmented RNA genomes, further indicating that the viral isolates are IPNV. Antigenic comparison of the IPNV isolates identified three distinct serological groups separable by the cross-neutralization test. Of the ten IPNV isolates, six could be classified as strain DRT, two as strain Ab, and two as strain VR299. We were not able to isolate new strain of IPNV or any isolate serologically similar to the standard strain Sp.poraceae and families of the Agaricales, they are genetically more related to the Polyporaceae. These results are consistent with morphological characters observed in those mushrooms. However, it is premature to conclude taxonomic status Ganoderma species in the present study employing small sample size.

With the diversification of mobile devices, the development of web technologies, and the popularization of the cloud, an internet-centric web OS that is not dependent on devices has become necessary. Chromebooks are mobile devices in the form of convertible laptops featuring a web OS developed by Google. These Web OS mobile devices have advantages of multi-user characteristics of the same device and storage and sharing of data through internet and cloud, but it is easy to collect and analyze evidence from the forensic point of view because of excellent security and easy destruction of evidence not. In this paper, we propose an evidence collection procedure and an analysis method considering the cloud environment by dividing the Chromebook, which is a web OS mobile device popularized in the future, into user and administrator modes.

The purpose of this study is to analyze the concept and characteristics of parody, and consider how parody was reflected in Thom Browne's collection centering on the expressive method. Thus, this study will attempt to shed new light on the creative possibility and artistic value of parody in men's fashion design. The methods are as follows. The ideas, characteristics and expressive methods that represent parody was considered by referencing various related books, papers, art critiques, etc. Based on this theoretical study, a case of Thom Browne's collection (Thom Browne menswear: 2004 S/S-2012 F/W) was observed to find types of parody, attributes and significance. Photo material was collected through websites such as www.thombrowne.com, www.style.com, etc. The type and characteristics of parody expressed in Thom Browne's collection was considered in the following aspects: imitative parody, critical parody and pastiche parody. Through such consideration, it was possible to realize the fashion designs that adapt Thom Browne's parody are very deliberate and calculative. The designs convey exaggeration, destruction of form, emphasis on discontinuity, transition into attraction, aesthetics of unfamiliarity, characteristic aspects of irrationality and contradiction. Through the study, it was possible to see Thom Browne's collection with parody adaptation shaping new creativity and broadening formative aspects in fashion design.

The retaining wall is a structure which was made for changing land form in many construction. The first role of the retaining wall is to maintain the slope stability. But recently, the amount of retaining wall have been increasing because of the expansion of construction works and the amenity of urban environment have been decreasing because of environmental destruction and the scenic heterogeneity. So we should consider the slope stability and ecological stability at the same time. The purpose of this study is to develop the retaining wall revegetation technology using the Eco-Stone, the structure of co-satisfying which included the slope stability and the revegetation effect. Eco-Stone is a structure which has high stability for earth pressure, settlement and drainage. And cost and term of construction works also have been decreased. Eco-Stone structure is one of factors composing the ecological network which is harmonize with surrounding environment. In this way, it is expected that the ecological habitats of various species would be restored.

Decadence is a phenomenon that people express fear from their inside, so unsound aspects appear in the social culture when the existing society is about to be collapsed. This study covered the cultural and aesthetic meaning and the role of decadence by examining the concept and phenomenon of it and analyzing the real case of expression appeared in the modern fashion. Characteristics of decadent phenomenon were divided into sexual corruption, ideality, cynicism and extreme technique, and decadent expression appeared in the fashion images was examined based on the divided phenomenon. Main results are as fellows. People bring the incidents that animals go through into relief, sticking to animal instinct when the society is on the decline. At that time, sexual decadence becomes remarkable, so voyeurism by exposure in their dress is deepen, revealing abnormal sexual propensity with bisexual tendency and sexual perversion. The real facts and appearance of people are revealed by transforming and distorting bodies for the fear of humans inside suppressed in the fin-de-siecle mood. The sense of alienation and helplessness of people anxious about the future is developed to cynicism expressing the uncertain emotion in their dress, and the formative methods of dismantlement. destruction and abrasion appear to form sickly images in the gloomy and cold mood. The intention of affirmative decadence is realized by mixing heterogeneous styles and producing new things. Extreme decorative technique and gorgeousness are even mysterious and show the highest refinement.

Rankine cycle using ammonia-water mixture as a working fluid has attracted much attention, since it may be a very useful device to extract power from low-temperature heat source. In this work, the thermodynamic performance of regenerative ammonia-water Rankine cycle is thoroughly investigated based on the second law of thermodynamics and exergy analysis, when the energy source is low-temperature heat source in the form of sensible energy. In analyzing the power cycle, several key system parameters such as ammonia mass concentration in the mixture and turbine inlet pressure are studied to examine their effects on the system performance including exergy destructions or anergies of system components, efficiencies based on the first and second laws of thermodynamics. The results show that as the ammonia concentration increases, exergy exhaust increases but exergy destruction at the heat exchanger increases. The second-law efficiency has an optimum value with respect to the ammonia concentration.

Kitsch is one of the various mass-cultural phnomena in the late 20th century, with it's own new aesthetic value, 'self-expression' through 'destruction', denying the existing established way of thinking and escaping from the stereotypes or fixed ideas. This is called 'aesthetic inadequacy'. The purposes of this study are to examine the different preferences between the western and the domestic Kitsch Fashions to investigate the formative and aesthetic characteristics of domestic Kitsch Fashion based on substantial data, and to propose the creative Kitsch design. The results of this study are as follows; 1. The formative characteristics of domestic Kitsch Fashion are marked by amusement, disharmony, epicureanism, satire, and use of imitation. 2. Then, based on theoretic research, this study applies aesthetic characteristics of Kitsch to the creative design. According to the formative characteristics for Kitsch Fashion, the Design Concepts are developed in order of Optimism, Multi Form, Decadence Chic, Neo-Naturalism, and Poor Vintage. And the Fabric direction is given in Design Story with sub theme such as Cheerful, Game, Decadence, Environment, and Grunge.
