Nowadays, a lot of software engineers struggle with the efficient back-end design of mobile application programs operated on the new mobile platform. It is simply because not only their lack of experiences in developing large scale system but also the unstructured nature of the mobile software, where there are no standard solutions. Furthermore, since big data is at the center of many challenges in system design of mobile software, so an efficient system design scheme is required for the development of such data-intensive applications. In this paper, we propose a systematic and efficient system design method that can figure out the substantial nature of the mobile software and solve the difficulties of the back-end software engineers.

Streptomyces are widespread in nature and play a very important role in the biosynthesis as well as biodegradation of natural and unnatural aromatic compounds. Both qualitatively and quantitatively through TLC and UV spectrophotometric assays, it was observed that the thermophilic soil bacteria S. setonii (ATCC 39116), which can utilize a benzoate as a sole carbon and energy source in a minimal liquid culture, was not very sensitive to the benzoate concentation and to the culture conditions such as the pH and temperature. The in vitro conversion of a catechol to a cis, cis-muconic acid by a crude S. setonii lysate implies that the aromatic ring cleavage by S. setonii is initiated by a thermostable catechol-1,2-dioxygenase, the key enzyme in the ortho-cleavage pathway of aromatic compound biodegradation. Unlike non-degrading S. lividans, S.setonii was also highly resistant to other similar hazardous aromatic compounds, exhibiting almost no adverse effect on its growth in a complex liquid culture.

This thesis aims to examine when the petroglyphs of Cheonjeon-ri, Ulju were carved and their nature. To achieve this, the relations between rituals and rock carving motifs are examined besides the nature of the archaeological monuments with carved petroglyphs. The investigation revealed that the figurative motifs on the petroglyphs of Cheonjeon-ri, Ulju, may have been carved during the Korean Bronze Age considering other examples of figurative petroglyphs from that period. It is reasonable to assume that the figurative animal motifs on the petroglyphs of Cheonjeon-ri, Ulju were used for rituals of fertility and rebirth as a subsistence ritual during the Korean Bronze Age. The Geomdan-ri Archaeological Culture Type is a strong candidate, having used both petroglyphs of Cheonjeon-ri and those of Bangudae, Ulju, since the Geomdan-ri Archaeological Culture Type has a higher proportion of hunting and fishing and lower proportion of rice cultivation in its subsistence than in the subsistence of the Songguk-ri Archaeological Culture Type. In contrast to the figurative motifs, the abstractive motifs, including the geometric designs on the petroglyphs of Cheonjeon-ri, Ulju, are generally accepted to have been carved during the Bronze Age. Although there have been some disputes over the symbolic meanings of concentric motifs, lozenge motifs, and other geometric motifs, they may be related to rituals for sun worship, ancestor worship, and fertility cults. Their meanings have been continuously reinterpreted.

The purpose of this study was to identify the origin of diversity of costume material caused by environmental difference. For this purpose, this research involved theoretical studies and studies based on historical data obtained from previous related studies. The common truth was proved that environmental including the geographical distribution of plants and animals determines costume material. Also, It was found that the unique traditional costume styles were developed through unique combination of costume material and their culture. The major results of this study are as follow : 1. The traditional costume of North American Indian was well-developed and closely related to geographical distribution of plants and animals. Also, their costume was so diverse that it could not be categorized. 2. The traditional costume of North American Indian showed ideal har mony between nature and human being surrounding environment into their costume. 3. The application of plants and animal materials into their costume was one of the environment-friendly human activity and it seems to give us an important message.

The Psychology of putting on clothes has close relation with sexuality, and eroticism is important in clothing. Present article aims to understand eroticism correctly and to make it evaluated as an art in modern fashion and as an aesthetic to express woman\`s beauty. Modern eroticism in fashion may be divided into direct, indirect and symbolic expression made. The result are as follow: First, direct made, a representation of desire into direct, indirect and symbolic expression of body or physical curve with tight garment. Second, indirect made, a see-though technique using association, represents sexual appeal by imagination on body area hidden by clothes made of see-through material. And third symbolic made express sexual libido by representing body area or clothes which symbolizing woman\`s sexuality using materials like fur or silk. Eroticism in modern clothing, therefore, should be understood as a beauty that is expressed by human artistic desire. Further studies are needed to explain the characteristics of eroticism in every culture because human nature is apt to from diverse kind of cultures.

The effort to generate new values in this age of digital technology characterized by rapid changes in information and knowledge demands transformations not only in the sociocultural and educational spheres but also specifically in the field of arts and culture education. One of the greatest transformations is emphasis on integration and consilience among different fields which has impacted the field of arts and culture, giving birth to the practice of arts and culture education. Digital technology actively utilizes in lots of subjects, which, also becomes a challenging factor for the field of arts and culture education. In this context, this study theoretically considered to approach music technology to use for the field of arts and culture education. Utilization of music technology takes interdisciplinary approaches combining various subjects in the field of arts and culture education. Considering the current circumstances in which there is a lack of teaching and learning methodologies which reflect the unique, specialized nature and the intrinsic originality of the field of arts and culture education. It is deemed that by accumulating more case studies applying music technology in practice to a wider variety of targets and situations. Music technology will serve the role of an important a learning tool for the arts and culture education field.

Fashion as a field of cultural studies is a very complex field that is very interesting to discuss, especially in Indonesia as the very rich country in cultures and past traditions. This research will discuss the development of fashion in Bali, one area that is opulent in its cultures. Based on the research conducted by today's fashion development, Bali is still strongly influenced by factors inherited from traditional values that exist in the Balinese culture. This research is conducted by applying the qualitative method with the ethnography approach to unravel any factor in Bali so that it becomes the foundation and triggers the rapid development of fashion by still maintaining the values of the tradition. Considering that the values of tradition as a whole have a good impact on the preservation of the natural balance and various factors that exist in society, whether these factors still exist in other regions of Indonesia and they are possible to be developed in various regions of Indonesia. So hopefully the development of fashion in Indonesia as a whole can maintain the local content that characterizes the Indonesian Nation and have a positive impact on the balance of nature and also to the community in Indonesia and the world culture.

The physiological characteristics of cultures of very high cell mass (e.g. 10g cell mass/L), termed“ultrahigh cell density cultures”is reviewed. A close relationship was found between the length of the optical path (OP) in flat-plate reactors and the optimal cell density of the culture as well as its areal (g m$\^$-2/ day$\^$-1/) productivity. Cell-growth inhibition (GI) unfolds as culture density surpasses a certain threshold. If it is constantly relieved, a 1.0cm OP reactor could produce ca. 50% more than reactors with longer OP, e.g. 5 or 10cm. This unique effect, discovered by Hu et al. [3], is explained in terms of the relationships between the frequency of the light-dark cycle (L-D cycle), cells undergo in their travel between the light and dark volumes in the reactor, and the turnover time of the photosynthetic center (PC). In long OP reactors (5cm and above) the L-D cycle time may be orders of magnitude longer than the PC turnover time, resulting in a light regime in which the cells are exposed along the L-D cycle, to long, wasteful dark periods. In contrast, in reactors with an OP of ca. 1.0 cm, the L-D cycle frequency approaches the PC turnover time resulting in a significant reduction of the wasteful dark exposure time, thereby inducing a surge in photosynthetic efficiency. Presently, the major difficulty in mass cultivation of ultrahigh-density culture (UHDC) concerns cell growth inhibition in the culture, the exact nature of which is awaiting detailed investigation.

The Pneumococcus, Streptococcus pneumoniae, has an ample polysaccharide (PS) capsule that is highly antigenic and is the main virulence factor of the organism. The capsular PS is the source of PS vaccine. This investigation was undertaken to optimize the culture conditions for the production of capsular PS by type 4 pneumococcus. Among several culture media, brain heart infusion (BHI) and Casitone based medium were found to support luxuriant growth of pneumococcus type 4 at the same level. Therefore in this study, the Casitone based medium was used to study optimization of the culture condition because of BHI broth's high cost and complex nature. The phase of growth which accomodated maximum PS production was exponential phase. Concentrations of glucose greater than 0.8% did not enhance growth or PS production. Substitution of nitrogen sources with other resources or supplementation of various concentrations of metal ion (with the exception of calcium, copper, and magnesium ions) had adverse effects on growth and PS production. On the other hand, low level aeration and supplementation of 3 mg/l concentration of asparagine, phenylalanine, or threonine were beneficial for increased PS production. The synergistic effect of all the favorable conditions observed in pneumococcal growth assays provided a two-fold cumulative increase in capsular PS production.
