  • Mankind has long made images. From cave paintings in the Old Stone Age when the dye was red clay, charcoal, or red iron ore to the modern digital images on the bases of 3D tools like Maya, images have been made through various methods. The basis of society's classification is the development of human beings and technologies. When we are familiar with three elements-technology, human, and art-we are able to create an image suitable for the trend of the times. As a consequence, we brought the trivium that had been taught by the monks in the Middle Age to set our subject to the trivium of the digital age. In this paper, we are going to put technology, human, and art into actual animation to check its theoretical discussion value.

  • Many studies in marketing and economics have attempted to model price and sales path under the dynamic diffusion process. Most of these models have been based on a fixed product lifetime. The current business climate requiring intensive development of new products however affects the diffusion of new products and their lifetime. Many products have not enjoyed the expected life cycle at the launching stage due to intense technical development competitive reactions, and financial problems. Most diffusion models however have not taken account of the lifetime uncertainty of new product. If the products do not last over the planning horizon set by those models. the optimal price derived from them could be futile. Therefore we had better take such lifetime uncertainty into consideration when developing diffusion models, In this paper we study the impact of uncertain product lifetime on its optimal pricing path in non-competitive market. We develop an optimal pricing model under uncertain product lifetimes and conduct a simulation study to investigate their effects on the optimal pricing and corresponding sales paths. The simulation study provides some interesting findings on optimal pricing policy under uncertain product lifetime. This study could be a stepping stone for the further extended study of optimal pricing strategy with uncertain product lifetime.

  • The children of sex workers in Bangladesh are denied even the most basic human rights. This article is based on recent research focused on the children of sex workers in the context of their everyday lives. The study focused on access to education and how education could be a vehicle for them to break the vicious cycle of exploitation. This was a mixed method interpretative study which employed qualitative and quantitative approaches, but in this paper only qualitative data which was generated through in-depth interviews and focus group discussions is used. Data was collected from sex workers, their children, teachers and NGO workers who participated in the study. Information has been collected for analysing the expectation of the children of sex workers and hope for the future, and the opportunities available to them during their schooling. Thematic analysis technique was used to understand the challenges and barriers faced by the children of sex workers in fulfilling their educational aspirations. The lives of the children of sex workers are marginalised by the mainstream society. Though it is very difficult to break the vicious cycle of exploitation, this research finds that education may be a stepping stone for them to create a better future. However, it is argued that the children of sex workers need income generating vocational and technical education to enable them to earn and support their family. Policy recommendations have been made in order to achieve Education For All targets and Millennium Development Goals, and to provide a second chance for these vulnerable young people to have a better life.

  • This paper attempted to analyze the Sainte-Chapelle(1242-48) in Paris in terms of Gottfried Semper's theory of four elements. For this aim, this study was divided into two parts: the first part regarding Semper's theory, which included not only the theories of four elements and four technical arts but also the concepts of the two types of primitive dwellings; the second part regarding the Sainte-Chapelle, composed of the overall study and the characteristics of the building and finally the analysis of it in terms of Semper's theory. The Sainte-Chapelle was regarded as a real example of Semper's four elements, in that the building was composed of a sacred altar containing Christ's earthly relics, stereotomic bases made of stone, a tectonic structure featuring linearity, and textile stained glass as an elaborate enclosure. While the bases and the structure were employed as serving elements, the altar and the stained glass played critical roles to make a whole space immaterial and monumental. These two elements served to reveal not only biblical typology but also the religious and political vision of Saint Louis to establish Paris is as a new Holy Land.

  • Gaecheonjeol is the National Foundation day of Korea when people hold a harvest ceremony. Nowadays, two representative harvest ceremonies of Korea are performed at Mt. Mari (摩利山) and Mt. Taebaek (太白山) on Gaecheonjeol (October 3rd). We study 28 flags with constellations appearing in the ceremony of Mt. Taebaek. These flags are lying in the outer of the circular stone wall during the ceremony. They represent an oriental heavenly star chart. We examine the shape, the connecting-pattern, the name, and the number of constellations drawn in the flags, and find several errors, such as, a wrong position, a typo of name, an irregular size, an omission, and so forth. Traditionally, the 28 oriental constellations are usually divided into four groups and each group has its own colour for each direction: Blue (E), Black (N), White (W), and Red (S). For the constellation flags in Mt. Taebaek, the colour of the flags is painted based on geographical directions, but the constellations are arranged followed by the direction of the celestial sphere. Thus, constellations in the northern and southern parts are counterchanged. Finally, we suggest some possible criteria for constellation map of the flags in this paper. CheonSangYeolChaBunYaJiDo (天象列次分野之圖) and CheonMunRyuCho (天文類抄) can be essential references for correcting constellations drawn in the flags of Mt. Taebaek.

  • Chemical-mechanical polishing (CMP), one of the dominant technology for ULSI planarization, is used to flatten the micro electro-mechanical systems (MEMS) structures. The objective of this paper is to achieve good planarization of the deposited film and to improve deposition efficiency of subsequent layer structures by using surface-micromachining process in MEMS technology. Planarization characteristic of poly-Si film deposited on thin oxide layer with MEMS structures is evaluated with different slurries. Patterns used for this research have shapes of square, density, line, hole, pillar, and micro engine part. Advantages of CMP process for MEMS structures are observed respectively by using the test patterns with structures larger than 1 urn line width. Preliminary tests for material selectivity of poly-Si and oxide are conducted with two types of silica slurries: $ILD1300^{TM}\;and\;Nalco2371^{TM}$. And then, the experiments were conducted based on the pretest. A selectivity and pH adjustment of slurry affected largely step heights of MEMS structures. These results would be anticipated as an important bridge stone to manufacture MEMS CMP slurry.

  • The amount used of aggregates for concrete is increasing rapidly since the mid-1980s in Korea. The natural gravels from river are already displaced with crushed stone, and use of crushed sand as a substitute of natural river sands, also, is getting increased day by day. This paper is presented fur analysis on mechanical properties of high strength concrete using fly ash and crushed sand. The material functions in mixing design of concretes are various water-cement ratios(w/c) such as 0.25, 0.40, 0.55 and different replacement ratio of crushed sand to natural sands such as 0%, 20%, 40%, 60%. As a results, it has been shown that compressive strengths of concretes with W/C lower than 0.40 and 0.25 are higher than 400 kgf/$\textrm{cm}^2$ and 600 kgf/$\textrm{cm}^2$ respectively. It is also concluded that the results of rapid chloride permeability tests of concrete are evaluated to negligible. The conclusions of this study is that it is possible to use fly ash and crushed sand fur high strength concrete.

  • Classification in biomedical applications is an important task that predicts or classifies an outcome based on a given set of input variables such as diagnostic tests or the symptoms of a patient. Traditionally the classification algorithms would have to digest a stationary set of historical data in order to train up a decision-tree model and the learned model could then be used for testing new samples. However, a new breed of classification called stream-based classification can handle continuous data streams, which are ever evolving, unbound, and unstructured, for instance--biosignal live feeds. These emerging algorithms can potentially be used for real-time classification over biosignal data streams like EEG and ECG, etc. This paper presents a pioneer effort that studies the feasibility of classification algorithms for analyzing biosignals in the forms of infinite data streams. First, a performance comparison is made between traditional and stream-based classification. The results show that accuracy declines intermittently for traditional classification due to the requirement of model re-learning as new data arrives. Second, we show by a simulation that biosignal data streams can be processed with a satisfactory level of performance in terms of accuracy, memory requirement, and speed, by using a collection of stream-mining algorithms called Optimized Very Fast Decision Trees. The algorithms can effectively serve as a corner-stone technology for real-time classification in future biomedical applications.

  • Until recently, domestic high grade limestone have mainly mined so high grade limestone deposits have reduced. Because of exhaustion of high grade limestone, mine of limestone have moved from ground to deep position, the grade of limestone become lower because the amount of impurities and colored mineral increased as mining position become deeper. This paper was described about grade improvement of limestone to make a high grade limestone and suitable quality of limestone products by analysis of ore genesis and characteristics, supply and demand situation, use patterns and application standards of domestic lime-stone.
