One of the characteristics of feudal society is the control of the dress and ornamentation which stand for various social classes and personal relationships. Throughout the Yi-Dynasty, certain forms of dress and ornamentation were controlled or prohibited by the government. For instance, there was a Ban on the use of gold and silver for ornaments and silks or satins for dresses, and the violator was subject to severe punishment according to the penal laws. This seems to have been done more for symbolism and the dignity of the various social ranks and powers than as an economic measure against foreign products. The use of yellow cloth, for instance, was once banned out of blind submission to the traditional practices in China, then the most powerful nation in Asia. The working classes were prohibited to use any silks of foreign production. This was done to discourage a spirit of wasteful luxury and the tendency to prefer the often higher quality foreign product. The government regulated the class of the traditional wedding ceremony, again as a means of both encouraging economy and reestablishing the distinctions between the classes. In spite of these attempts at control by the government a large trade in smuggled goods was still carried out. This had the effect of impeding the development of the clothing industry in the country.

The purpose of this study is to understand the relationship between the environmental movement and voluntary simplicity life style. The results of this study are as follows： First, both voluntary simplicity life style and the environmental movement are concepts which became the center of public interest because of the evil practices appeared in the process of the development of capitalism. Second, the level of consciousness of environment is comparatively high, but the level of the power of execution is comparatively low as a whole. In the case of Korea, people have not yet the mature responsibilities of citizenship. It is very important to enforce different informal educations in order to increase the effectiveness of the environmental movement. Home training based on voluntary simplicity life style is the most important informal education for the purpose of increasing the effectiveness of the environmental movement. Consequently, for the preservation of environment we need to do our best endeavors such as home training based on voluntary simplicity life style, environmental education based on our social and cultural background, and more powerful administrative measures which is administrative support rather than administrative control.

This paper describes the implementation of Direct3D interface library for Python language. DirectX is the most popular library used for 3D games and 3D modelings. However, softwares which use the library can only be developed in the environments provided by Microsoft like Visual Studios and .NET framework. The interface module for Python, this paper presents, will extend the coverage of the useful library DirectX to a language which is not fully supported by Microsoft. The interface techniques described here can be a guide to develop interface modules for other languages too, which make their language more powerful and extensible. This paper describes the implementation techniques to develop the interface module for Python, advantages and disadvantages.

Luminous infrared galaxies (LIRGs; $L_{IR}$ > ${10^{11}}_{Lsun}$) are the most powerful objects in the local Universe. Previous work suggested that dust re-processing of starburst and/or active galactic nuclei (AGN) activity, triggered by galaxy interactions, is responsible for their enormous infrared emission. To understand the nature of LIRGs, it is essential to determine their spectral types. Optical spectral types of 115 ultraluminous infrared galaxies in the southern sky are presented using CTIO observations. The AGN fraction is on average 50% and increases with infrared luminosity. Near-infrared spectral types of 36 LIRGs are also presented based on AKARI observations. In the sample, 12 optically elusive buried AGNs are found. To investigate the evolutionary sequence of LIRGs, star formation histories of ~6000 LIRGs in the SDSS and IRAS/AKARI matched sample are derived by comparing observed optical spectra and stellar population models. AGN-dominated LIRGs are currently massive relative to starburst-dominated LIRGs, which originates from an enhancement of star formation at intermediate-ages. For ~1100 early-type LIRGs, optical and NIR fundamental planes (FPs) are constructed. The FP of LIRGs is significantly different from that of normal early-type galaxies, but the difference is minimized in low luminous and AGN-like LIRGs. These findings support that the importance of AGN is growing as infrared luminosity increases and that LIRGs follow at least in the high mass regime the standard evolutionary scenario: starburst LIRGs evolve into AGN LIRGs and finally into normal early-type galaxies.

Many papers point out that the e-Learning is one of the most important industries, and the effect on other industries can be more powerful than any other business. Therefore, we think about social, cultural, industrial and technological effect of the e-Learning in order to enlarge industry scale as well as educational performances. In many cases of developed countries, various kinds of study have been performed for the e-Learning quality assurance because quality of the e-learning should operate on effective and efficient learning and continuous market development of education industries. The e-Learning quality assurance has import function not only for learning contents reusability like a SCORM and metadata but also for learning system, solution and service operation, so activities for the quality assurance should consider of cultural and tactical approach when it is applied in the e-learning business. In this paper, we present the concept, domain and purpose of the e-Learning quality assurance. Furthermore, this paper proposes the process and methodology in order to make the quality assurance standard model which is consist of 6 phase such as Environment Research, Needs Analysis, Framework, Metrics, Development and Implementation, Evaluation and Feedback through the analysis and comparison of pre-studied worldwide quality control, management and assurance documents.

Fluorescence imaging is considered as one of the most powerful techniques for monitoring biomolecule activities in living systems. Near-infrared (NIR) light is advantageous for minimum photodamage, deep tissue penetration, and minimum background autofluorescence interference. Herein, we have developed a new NIR fluorescent dye, namely, RB-1, based on the Rhodamine B scaffold. RB-1 exhibits excellent photophysical properties including large absorption extinction coefficients, high fluorescence quantum yields, and high photostability. In particular, RB-1 displays both absorption and emission in the NIR region of the "biological window" (650-900 nm) for imaging in biological samples. RB-1 shows absorption maximum at 614 nm (500-725 nm) and emission maximum at 712 nm (650-825 nm) in ethanol, which is superior to those of traditional rhodamine B in the selected spectral region. Furthermore, applications of RB-1 for fluorescence imaging in living cells and small animals were investigated using confocal fluorescence microscopy and in vivo imaging system with a high signal-to-noise ratio (SNR = 10.1).

Livestock is considered as one of the most important segments in agriculture since animal husbandry was practiced for centuries as a backyard system by rural families. Livestock plays as a powerful tool in rural development where meat industry contributes a dominant part. Meat and meat products become a vital component in the diet, which had been one of the main protein sources traditionally as well. The development in the livestock and meat industry of Sri Lanka basically depends upon religious, cultural, and economic factors. There is a growing demand for processed meat products in Sri Lankan urban culture and several large scale processors entered the business during the past few decades. The consumption of meat and meat products shows an upward trend in Sri Lanka during the last decade and is anticipated to increase further in future. The growth potential of the local meat industry is considerably high owing to the improvement of the market and consumer perception. The present status, trends, and future prospects for the Sri Lankan meat industry with respect to production, consumption, processing, marketing, and improvement are discussed in this review.

The major components of an engine are engine block (or cylinder block), cylinder head, crank shaft, connecting rod and cam shaft. Thus the engine shop usually consists of six sub-lines, five machining lines and one assembly line. Flow line is the typical concept of layout for machining these parts, especially for engine block. In order to design an engine block machining line, several factors should be considered such as yearly production target, working hours, machines, tools, material handling equipments and so on. If the designers of manufacturing line were unaware of some factors those would be influenced on the system performance, it would make greater problems in the phase of mass production. Therefore the initial design of engine block machining line should be verified carefully. Simulation is the most powerful tool for analyzing the initial layout. This paper introduces the major factors those should be considered for designing the machining line and their effects on the system performance. 3D simulation models are developed with QUEST. Using the simulation model developed the initial layout is analyzed, and we suggest some ideas for improvement.
