The Organic agricultural techinques were investigated through the observations made for 3 years of the actual conditions of a farmer who has been practicing organic agriculture over 21 years. The farmer was a member of the Ichijima-cho Organic Agriculture Association. The Farmer had not performed much of the organic agricultural techinques at the beginning of his farming history. However, he has gradually developed techniques upon the experiences with trial and error. The notable characteristic of his basic organic agriculture was the utilization of a suitable organic fertilizer to make the soil fertile. Crop damages by diseases and insect pests were prevented through a fertile soil, raising of good seedlings, adoption of tolerant varieties and planting at a wide spacing and consequently considering not to use chemical pesticides. Introduction of power weeder for weed control and paddy-upland crop rotation reduced the cost of production for farming. The crop pattern and method of land us such as mix cropping, crop rotation and conversion of paddy field-upland fieldd were appeared to be very important in organic agriculture. The organic agricultural techniques get systematized upon the adaptation the regional ecology and the development of skills of the farmer. The most important point to achieve the success in organic agriculture system is not only by the development of the technical matters but also by the building of healthy relation and understandings between producers and consumers.

This paper explores differences demonstrated by changes of consumers' clothing expenditure in Korea and the United States since the mid-1990s. Evidence for this study was extrapolated from annual data provided by the Household Expenditure Survey, which was carried out in Korea between 1996 and 2008, and the Consumer Expenditure Survey, which was carried out in the United States during the same time period. The results include: (1) The proportion of the clothing expenditure decreased during the subject period in both Korea and the United States; (2) The decrease in proportional clothing expenditure was greater in Korea than in the United States; (3) Although the relative prices of clothes decreased greatly during this period in both countries, it was determined that the decrease in clothing prices in the United States was greater when compared to those in Korea; and (4) By using the DID(Difference in difference) model, the author contends that a decrease in clothing purchases contributed to the decrease of prices for clothing in the United States, while in Korea, the decrease in prices for clothing was also impacted by other factors including changes in household expenditures for education and communication.

Social media is considered a valuable platform for gathering and analyzing the collective and subconscious opinions of people in Internet and mobile environments, where they express, explicitly and implicitly, their daily preferences for brands and products. Extracting and tracking the various attitudes and concerns that people express through social media could enable us to categorize brands and decipher individuals' cognitive decision-making structure in their choice of brands. We investigate the cognitive network structure of consumers by building an inter-category map through the mining of big data. In so doing, we create an improved online recommendation model. Building on economic sociology theory, we suggest a framework for revealing collective preference by analyzing the patterns of brand names that users frequently mention in the online public sphere. We expect that our study will be useful for those conducting theoretical research on digital marketing strategies and doing practical work on branding strategies.

Air Transportation industry becomes more competitive that the restriction on new access to market were eased and relaxed. Liberalization of international air transport will continue, via bilateral and multilateral process. Korea, Japan, and China have expanded enormously the economic trade and cultural exchange bilaterally in the Northeast Asia, they are acknowledging the importance and necessity of improved connection, it order to face effectively other regional blocks of US-Canada, NAFTA, ASEAN, CLMV. In particular, nobody denies that it is urgent to liberalize bilaterally the air transport in Northeast Asia for promoting reciprocal benefits and prosperity. Recently while open skies bilateral agreements was signed between Korea-China in June, 2006. The agreements processes are too heavily influenced by flag carriers; leading to capacity/market sharing between the bilateral carriers in most markets, against the interest of consumers and overall economic interest of the nation. For successful operation of Northeast Air Market, it is need to set up development strategy paradigm by creating cross-border sub-regional (Northeast Asian) open skies bloc as well as preparing and creating of LCCs operations.

Country of origin is very important in terms of consumers right to know, protection of producer, national finance and tariff preference etc. The principal issues related to country of origin are breaches of origin mark, determination of origin of OEM products, domestic products using imported raw materials, exports products, and fairness of penalties. This study focus origin mark issues on key components and set products which have not been treated so far. First, Origin mark issues on key components need to introduce multiple countries of origin for the same products. Some specific products, which are considered important key components or materials, has to mark multiple country of origin in terms of portion and significance. Next, Origin mark issues on set products need to expand the objects from 15 listed items of Korea Foreign Trade Act to all items of HS tariff schedules of Korea Customs Act. A set products which below 15% of components can mark single country of origin like FTA agreement such as Korea-EU FTA, Korea-EFTA, Korea-US FTA and Korea-Peru FTA.

Buttons in general reflect the culture of the society, and their values depend on practicality, decorative feature, and symbolism. Their infinite potential enables us to attempt various original changes in formative factors such as forms, patterns, colors, materials and sizes. In addition new styles, methods, and techniques are tried to show that the decorative feature becomes stronger today than it did in the past when the function was more important. Now buttons are not only a factor of clothing but have value as composite art works reflecting the pride, idea and culture of a nation. Moreover consumers' interest in new designs increases everyday as the moderns' desire for unique individuality rises. Button designs of Korea, however, are still far behind in the aspects of materials, qualities, and methods, facilities, and scale of production. And uniform mass production prevails without the buttons of creative and artistic values made due to the lack of specialized designers. Therefore it seems necessary to carry out historial studies simultaneously with the rising interest in button designs now. Prior to developing new designs, the study will examine those of western buttons that are the origin, going through relevant literature and data to define the characteristics of each era and type. It may provide basic data for developing the backward button designs of Korea.

This study compares the buying patterns of American and Korean female college students in relation to their self-concept. It was implemented through self-administered questionnaires which were back translated for validity. Respondents comprised 730 female students majoring in fields related to clothing and textiles: 307 U.S. students were located in the Northeast, West, and Southwest, and 423 Korean students were at four universities in Seoul. Likert scales were used for most measures, with 1 = never or very unimportant, and 5 = always or very important. Personal self-concept was measured on the basis of Won-Shik Jung's Standardized Self-concept the Test and Tennessee Self Concept Scale. Data were analyzed by descriptive statistics and t-tests. Some clear differences between the two countries emerged. Marketers targeting American consumers should pay more attention to practicality and service, and for Koreans, more symbolic meaning of products and store displays, since these are important to them. Self-concept was somewhat related to purchasing behavior, but more study should be done before applying findings to marketing concepts.

This manuscript treats a new paradigm for the Korean health care system. We give an account of innovative health care delivery and payment models widely discussed in the contemporary US accountable care organization and coordinated care organization. In doing so, we explore a new health care model amenable to foreseeable changes to the health care system. We propose creating an integrated health care system in which the network of health care providers delivers coordinated and comprehensive care for enrolled patients residing within the geographic boundaries served by the provider network; providers may participate voluntarily in one or more networks and assume shared responsibility for patient care and cost; provider networks compete with each other based on cost and quality; and consumers are allowed to choose a network. We expect that the new paradigm will create a financially-sustainable system that assures quality of care and improves patient experience, minimizing the existing system-wide inefficiency through cross-network competition and within-network care coordination.

Recent trend of popularity of CAE(Computer Aided Engineering) tools and its availability, partly contributed by significant price reduction of H/W and SW, makes us believe CAE has already established terra firma as de jure tools, enablint the design improvement in the manufacturing am. However, if your jobs are required to be working closely with engineers located in the front line of manufacturing site, CAE is observed far from popularity, still being regarded as exclusive tools for engineers holding advanced degrees. Conventional methodologies depending on knowledge that was accumulated thorough trial and errors, depending primarily on engineering tables and formulas or proprietary know-how, are preferred as the de factor standard under the roof of contemporary development shops. Samsung camera, having stared its business since early 、80, has accumulated enough technological strength to compete in the world market. As today's consumers demand more sophisticated featured-lighter weight, built-in multi zoom and miniature size fitting in the palm-from camera manufacturer, so should Samsung camera respond to ever-delicate consumer's needs with great flexibility. Consequently conventional designers, without sophisticated analytical tools, with encounter solving the critical design factors that have never been treated as seriousness-marginal safety factors induced by reduced size of parts. In the study, CAE results of boss and gears were demonstrated as examples, which confirms the facts that the simple analysis done by front line designers, can bring distinguishable effects on the potential improvements of design and on the consequential influences on the future design process-simulation before actual tooling and productions.

Water distribution systems supply drinking water to consumers' taps. Internal corrosion of metallic pipe used in drinking water distribution systems has reduced water quality and led to increased levels of toxic heavy metals such as lead, copper and nickel. These problems have been experienced to varying degrees by water utilities in many countries. North America has successfully managed and controlled pipe corrosion and corrosive water in water distribution system based on various policies, regulations and rules. Practical and engineering guidelines for evaluation of pipe corrosion and determination of treatment options are also provided to assist drinking water supplies. In addition, the corrosion mechanism in water distribution systems, such as the complex effects of physical and chemical parameters on the corrosion pipes has been improved to accurately predict corrosion rates of metallic pipes in actual water distribution systems. This paper reviews various regulations, policy statement, and treatment produces on controlling corrosion in drinking water distribution systems in US and Canada and then offers suggestion for management of corrosive water and pipe corrosion in drinking water distribution system in Korea.
