Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment preservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. For the building or construction project, its possible impact on environment during construction work and after completion must be predicted at its design phase, which will result in the completion of the architecture convenient for human being with its environmental pollution reduced to minimum level. In this study, the checklist of environmental factors was suggested, which should be taken into account at its design phase in conducting the construction work. Proposed checklist was linked with the developed web-based system for the convenience of users like designer and construction manager, etc. It is expected that the checklist suggested by this study will help the designer and construction manager to continue the steady development from the environmental viewpoint during the design phase.

Yogurt contains many microorganisms that are beneficial to human health, and is a probiotic that supplies many nutrients such as calcium and protein. It is difficult to safety preserve for a long time because it possesses a high content of water. To address this problem, powdered "instant" yogurt has been developed, but it has flaws low flowability and solubility. Therefore, yogurt was granulated using a fluidized bed granulator to increase flowability and solubility. The fluidized bed granulator was designed by using response surface methodology (RSM), whose variables were feeding rate (FR), atomization air pressure (AP) and product temperature (PT). After being granulated, the yogurt was analyzed for yield and lactic acid bacteria count. The maximum yield of yogurt granules was 79.42%, at FR of 0.54 mL/min, AP of 2.64 kPa, and PT of $58.18^{\circ}C$, and the colony count for lactic acid bacteria was more than $6log^{10}\;CFU/g$. Therefore, spherical granulation of yogurt using a fluidized bed granulator could be used for making convenient probiotic products with improved flowability and solubility.

The rural traditional houses in Taebaek mountainous regions play important roles in figuring out values and social aspects of past time including housing life. But due to the introduction of convenient facilities in the current housing life style after industrialized society, many transformations have been taken place even to exist rural traditional folk houses such as installation of new equipment and furniture, the arrangement and function change of rooms, expansion of residential area and etc. So this study aims to secure basic data to prepare installation standard of the convenient facilities as examining convenience facility installation status of the cultural asset designated as rural traditional house, and to identify the meaning and usage of major room of rural traditional houses in order to prepare the proper balances between its original form preservation and residents' convenience living.

Dairy products, including milk, cheese, cream, yogurt, and butter, constitute excellent sources of essential nutrients such as calcium, proteins, and vitamin D; therefore, nutritionists recommend a constant daily dietary intake of dairy products. Packaging is an important feature that ensures high-quality products are delivered to consumers; different packaging materials and forms are required depending on the products. Packaging forms include pouches for butter, cheese, and milk powder; cartons for liquid, frozen, and coagulated milk; packets for pasteurized liquid milk; bottles for milkshakes and other liquid products; and cups for frozen and coagulated products. The increase in mobile lifestyles among consumers will lead to smaller households and greater preference for convenience, which will promote individual and smaller packaging for dairy products. This article reviews the development of packaging materials and forms, packaging requirements, and future considerations for the packaging of dairy products.

For the purpose of improving microbiolgical quality of carrot powder, which is being used as minor ingredients of convenience foods, comparative influence of Υ-irradiation and ethylene oxide(E.O) fumigation was investigated with emphasis on sterilizating effect and physicochemical propertied Carrot powder sample was contaminated with thermophiles 4.0$\times$103/g, acid tolerant bacteria 3.7$\times$103/g and coliforms 1.6$\times$102/g, respectively. And thus sanitation process was required. E.O fumigation in commercial practice was not enough to destroy thermophilic bacteria, while Υ-irradiation at below 5 kGy could reduce all microorganisms up to undectected levels. Radiosensitivity(D10) of thermophiles was shown to be 2.25 kGy. The applicable dose of irradiation to the improvement of microbiological quality showed insignificant influences on the physicochemical quality of the sample.

Liquid nitrogen storage is the most effective way to preserve many fungi including what cannot be lyophilized. The use of polypropylene straws instead of cryotubes has many advantages in economy, safety, convenience, and space-saving. We, Korean Agricultural Culture Collection (KACC), established the fungal preservation methods in liquid nitrogen using polypropylene drinking straws and introduced the methods in detail.

In order to develop of health-oriented convenience foods for rice consumption, functional Misutkaru drink was made by adding several medicinal herbs extracts to fundamental Misutkaru based cereal powder(rice, barley and soybean). Fundamental Misutkaru drink was prepared with the ratio of cereal mixed rice(5g), barley(5g) and soybean(5g) on water (100 mL) and several medicinal herbs extracts. Liriopis Tuber(50%), Omija(15%), Ginseng(10%) and Jujube(25%) were mixed to fundamental Misutkaru as functional Misutkaru. And then it was extracted to added water of 10times during 36hrs at 75$^{\circ}C$. For instant Misutkaru drink of health-oriented convenience foods, mixture of them was made with fundamental Misutkaru drink(80%), extract of several medicinal herbs(20%), and it's sensory score was high. Autoclaved functional Misutkaru drink for long storage period was changed rheological type badly. Overall acceptability and storage period of nonautoclaved functional Misutkaru drink to added extract of several medicinal herbs was higher than fundamental Misutkaru drink.

This study examines the change of Shinchon railway station in Kyungui Railway from 1920 up to now. Kyungui Railway was constructed in order to prepare the war against Russia by Japan in 1905. Shinchon station was constructed in 1920 for the sake of convenience of people who lived near Seoul. Recently the development of Shinchon staton was demended because of the possibilities of economic development and the location of Shinchon station. But at the same time there are many opinions against the development of Shinchon station because it has many great memories and it is a kind of symbol of modem life in Shinchon. Even though Shinchon station has developed for a shopping center, the location of the old station has been kept. But the shape had changed because of the new railway station. So the purpose of this paper is considering how to solve the conflicts between the development and the preservation of historic places in the cities which is one of the most serious pending issues.

The purpose of this study was to understand users' attitudes for trail structure conditions in Dobong district, Bukhansan National Park, Korea. For this purpose, the research conducted a respondent's-personal entry-method based questionnaire survey on 250 visitors using inquiry routes in Dobong areas in Bukhansan National Park in July, 2007. The survey result showed that the 6 types of pedestrian trail structures were relatively in better shape in its quality and quantity while the responses for 3 types of structures, such as wood deck, wood railings, and stone paving, were positive in terms of harmony with landscape, preservation of resources, and user convenience. In conclusion, it is considered to be essential to bring in nature-friendly materials for walking facilities in National Parks and also necessary to consider the visual effect arising from the harmony with landscape together with the functions of conservation of resources and inquiry convenience.
