This study aimed to develop an agroforestry technology through the participation of local people. The study was conducted in the Makiling Forest Reserve (MFR) of the University of the Philippines Los Banos (UPLB). Diagnosis and Design (D&D) methodology was employed to plan and implement effective research and development projects. Diagnostic interview and direct field observation were conducted to identify the significance of the land-use system and to understand how the system works. As a result of the diagnostic interview and direct field observation in San Vicente, old coconut-based land-use system is shifting to mahogany-based agroforestry system. One of the reasons is due to the very complicated socio-economic and silvicultural factors including lower price of coconut farm products, industry development, lack of labor force, and pest and diseases. Change in land use brought about by the shifting to mahogany-based farming system is slow. Also, mahogany trees are observed to be not well-maintained. However, mahogany based land use system gives farmers' a bigger income as well as environmental benefit. Farmer's cooperation and local forestry policy for CDM were proposed to encourage people's self-restoration effort.

U-City means the high-tech city that applied ubiquitous technology and information communication technology. U-City aims to intensify urban competitiveness and to improve the quality of residents' life through efficient management of the urban. Currently, 77 U-City projects is underway. The each project cost and scale estimate is not clear in the absence of the U-Service Standardization Model. So, many of the project are trouble about making a production the proper number of U-Service or the cost of project. The excessive service construction is reflected on the construction costs, which leads to the rise of sales price and passes onto the executor of a project as a burden of the project costs, and the problem of the delay of the change-over occurs due to supporting the operation costs for the operation of the constructed service and the demand for additional installation of facilities between a local autonomous entity and the executor of a project. In this paper, we suggested the U-Services Construction Standardization Methods and proposed the standardization services guideline of crime prevention services. U-City services in the future are able to maintain the consistency of the system through the utilization of the proposed standard model. As a result, the U-City project's pre-estimated cost and scale can be extracted.

This study was carried out in order to analyze a repletion possibility about color change of base paper after elevated heat exposure when wooden fillers were added. Fillers may reduce production cost because its price is usually inexpensive than pulp with higher bulkiness. Wooden fillers have lower density than inorganic fillers, so they may increase bulk more than inorganic fillers. Never the less wooden fillers have disadvantage of yellow color by heat exposure, so the addition level should be carefully controlled. Brightness and whiteness changes after elevated heat exposure depending on coating weight were analyzed. With wooden fillers addition, breaking length and surface strength decreased but bulkiness increased. As the exposure time of elevated heat increased the coating paper with wooden fillers addition had higher brightness and whiteness values than those of inorganic fillers.

Fast food restaurants are growing in numbers in Korea since they were introduced abot a decade ago. To develop an effective marketing strategy for fast foods, it is important to assess consumer's acceptability and identify demorgraphic, environmental, and managerial factors which influence consumer's perception on the fast food restaurants. A total of 595 customers were surveyed at thirty hamburger chain restaurants in Seoul from November 7 to 15, 1988. Analyses of the collected data revealed that adolescents, females, and the people with high income were the major customers and visited more than once or twice a week; frequent visitors rated meals more favorably in terms of the quality, service and cleanliness, and they also rated meals of foreign brand more favorable than those of domestic one; the female group perceived the change in their dietary habits more than any other groups; cleanliness, convenience, atmosphere, courtesy, and the taste of foods were significant factors in purchasing fast foods; and customers were most satisfied with convenience, while least satisfied with the price and the quantity of foods. From these findings, it is sggested that the manager of the fast food restaurant must consider the consumer's perception of fast foods in terms of pros and cons in order to operate her/his restaurant successfully.

The purpose of this study is to examine the main characteristics of strategies and fashion styles in fast fashion. Ultimately, this study is aimed to give useful information to develop fast fashion companies in Korean apparel industry. There are several strategies commonly applied in most fast fashion companies. First, they produce a wide range of numerous items. Second, the price is very reasonable. The primary objective of fast fashion is to quickly produce products in a cost efficient manner. Third, fast fashion companies take charge in the whole process from designing and manufacturing to distribution and sales. Forth, while almost all apparel companies invest a large amount in advertisement to promote sales, most fast fashion companies invest in VMD instead. Also, the fashion style of fast fashion were examined. First, casual style dominated a big part in composition of the entire style. Second, they use various kinds of different fabrics. For example, natural fabrics including organic and recycled fabrics, denims, newly invented high-tech fabrics, and decorative fabrics are widely used. Third, fast fashion brands produce fashion product based on the most recent fashion trends. Forth, they pursue high quality design. Retailers' understanding of the target market's wants realizes the consumer to thrive on constant change and the frequent availability of new products. Accordingly, fast fashion is presently taking an important role in fashion although it has a short history compared to the general apparel industry.

The purpose of the study is to review the evolutional process of the U.S. broiler industry into the integrated production and marketing systems and to examine the factors influenced such a structural change over the Past half a century. The study is also carried out under the consideration that the experience gained by the integrated U.S. broiler industry could be utilized in applying the system to any non-integrated broiler industries like one in Korea. The U.S. broiler industry has been prevailed in the typical independent operation of all stages, from factor supply through growing to dressing and marketing until such time as growers began to suffer from financial difficulties right after the end of the World Wat II due mainly to lowered price of broilers stemmed from whopping decrease of the demand, which eventually reflected to the allied agribusiness sectors. The feed business field was the first reactor to this situation so that a kind of measures was taken to cope with the problems faced in such a way to provide extended credit on feeds first and help obtain chicks or sell broilers later. This trend has been practiced for broiler related agribusiness through late 1940's to work together with growers by coordinating its function between two or more stages involved in broiler production and marketing process as a means of spreading risk and sharing profit between stages Participated. The integrated system and contract farming thus became Popular across the country through mid 1950's.

Recently, it is one of the popular fashion and cultural events that people of the younger generation put on a hanbok and take a picture together with communicating by SNS. For this reason, the rent-hanbok market takes a big part of the Korean traditional costume market. Therefor, the recognition of hanbok is changed from the style of uncomfortable and ceremonial clothes, to becoming popular as everyday dress in the younger generation. The various designs of the rental hanbok show two different opinions. One is the increasing popular and general public interest and demand for wearing and showing off traditional hanbok fashions in a positive outlook. Another is the case of the wrong stereotype and knowledge for traditional costume which results in a negative outlook for this type of fashion statement. This study is to look into renting hanbok jeogori for women in Seoul and in Junju. There are 39 styles available in joegori. That being noted, the traditional jeogori has seop and git with dongjung. But it is seen that rental jeogoris do not have the seop, or have the dongjung position as similar to the Po as seen on the men's coat. The showy and colorful materials feel bad and are poorly ventilated. And excessive price competition causes a decreased quality of renting hanbok. Now the rental hanbok business needs to change; to have to make renting hanbok with the correct historical understanding, and it is necessary to have to stop the indiscriminate acceptance of foreign culture.
