Central government and local self-governing bodies are actively promoting bicycle-riding as a solution for transportation, environment, energy and health. They put lot of efforts in the practice of bicycle-related policies such as building bicycle-related infrastructure and creating task force team to improve the bicycle-related systems. However, there is no substantive improvement in the city rail operation agencies regarding the bicycle-related facilities and operation. The expansion of bicycle-related infrastructure in city rail stations is urgently required considering the increase in demands from the bicycle-riders for the facility and bicycle-related service improvement. Accordingly, this study suggests a bicycle-riding vitalization plan linking the city rail and bicycle by providing with a bicycle custody place in the city rail stations which will have comprehensive convenience facilities including the safe-keeping facility for bicycles.

The purpose of this paper is to suggest a proposal for the betterment of the English curriculum in the Department of Tourism of a women's college. The paper includes not only the needs analysis of students but also that of personnel officers of tourism related companies and offices. Since the students will have to look for desirable jobs after graduation, the needs and demands of their potential employers or personnel officers are crucial in deciding what and how to teach. Based on these analyses, the paper also examines the current curriculum offered by the department. The needs, wants and necessities of the students, potential personnel officers, and the current curriculum will have to be taken into consideration in designing a more effective future curriculum. The results of the study reveal that more emphasis should be given on the improvement of students' communicative abilities and TOEIC scores.

Agrobacterium-mediated transformation has been unsuccessful for monocot plants except for a few important crops such as barley, rice, maize and wheat. We discussed here that a successful transformation of monocots demands certain critical conditions. The requirements for an efficient transformation are a selection of target tissues competent for plant regeneration and Agrobacterium-infection, and various factors promoting Agrobacterium-infection. The factors were divided into two to activate Agrobacterium and to increase plant cell's susceptibility against Agrobacterium. Optimization of these factors significantly increased transformation efficiency of zoysia grass and rice plants. A technical improvement in transformation system for monocots will promote improvement of the breed as well as a study of gene functions in monocots.

Manufacturing companies' cost competitiveness with respect to equipment management can be achieved by satisfying additional market demands by their own capacity without purchasing additional equipments. In essence, it can be accomplished by making continuous investigation into bottlenecks and improvement on them. Therefore, equipment performance measure systems should be designed so that they can support manufacturing companies' such endeavors. With the purpose of establishing an effective equipment performance measurement system for detecting and improving bottlenecks, this study (1) suggests some desirable features that such a system should have, (2) evaluates conventional equipment performance measurement systems in terms of their usefulness for the detection and improvement of bottlenecks, and (3) proposes an improved system. We also perform a simulation experiment to demonstrate the limitations of the conventional systems and show how the proposed system can resolve the problems.

The premise for the study reflected in this article is the need to dispose of industrial waste, which is increasingly being used in the construction materials industry. Also, dynamically developing building industry demands attention of scientists and a direction of their works on improvement of the technology of carrying out construction works. Thus, the article is devoted to studying the influence of various chemical additives and fine fillers (industrial wastes) available in Kazakhstan on self-compacting concrete (SCC) mixtures and its rheological, physical, and technical properties. According to the studies, revealed the most efficient type of fine-dispersed filler and the most optimal type of chemical additive to enable obtaining a high-quality SCC mixture based on local raw materials. As a result, the use of microsilica in comparison with other industrial wastes resulted in a conglomerate with high compressive strength of SCC at early terms of curing. In terms of economic efficiency and quality improvement, the results of study are of practical value for the manufacturers of ready-mixed concrete operating in Kazakhstan.

On facing the information society, the multi-faceted information utilization and the establishment of synthetic information management system in the overall industry and business administration have raised considerable attention. Thus, this study aims at the improvement of freight transport management through the establishment of pooling of the road freight transport information system as its effective information supporting system. Especially, it describes the freight transport information network, structure, function, and subject of the freight transport information center, as a basic planning design for the freight transport information system. Furthermore, it deals with the identification of the systems design requirements, working process, and S/W & H/W design specifications. Finally, we expect that this study will be contributed for the improvement of the road freight transport business to meet both the increase of freight transport demands due to the continuing economic growth and the social needs for the establishment of transport-order.

Recently the construction of high-rise reinforced concrete building is progressively increased as the social demands. It is significantly important factors such as economy, the safety of structure, and the flexibility of internal space. Therefore new structural system is also required to be attained the reduction of story height, the flexibility and efficient use of space. The most suitable structural system is with the economy and flexibility, flat plate slab system in high-rise reinforced concrete building. In this research, it was focused in the improvement of shear performance in the flat plate system using high ductile fiber reinforced mortar. It was evaluated the shear performance in the critical region of slab-column connection. The flat plate system, designed by the high performance and safety, was developed as a new technique in the application of high-rise R/C building.

In modern society, population overcrowding and concentration of facilities are happened because of the concentration on to city. So this phenomenon demands improvement of material's performance, technical development of structure analysis and design and improvement of constructing ability .High strength concrete has some merits. High strengthening makes the cross section reduced, and that cause decrease of structure weight. And using high durable and superplasticizer promote liquidity, thus high quality concrete can be produced. Because of these advantages, this study is for showing validity of using it by compression/tensile strength experiment. As this experiment's result, when concrete become stronger, interface intensity coefficient between cement and aggregate is different and they don't adhere to each other. So there is brittle failure. Fragility factor also steadily increase with strong concrete, it tells high strength concrete has problem. Therefore the sources used in high strength concrete like cement and aggregate must have great quality. So the source's performance must be supervised well because their quality decides performance criteria.
