  • Environmental Impact Assessment(EIA) is defined as an activity designed to identify and predict the impact on the environment. In the process of an EIA, the quantitative evaluation is generally performed for the air and water quality which have the national environmental quality standards. But the predicted values for the air and water quality are simply compared to the environmental standards. At present, the EIA process of Korea has no consideration for the possible human health risk resulting from the development projects. Environmental Health Impact Assessment(EHIA) is an applied methodology of EIA to estimate the acceptable health risk caused by a specified level of environmental pollutants. Estimating the excessive lifetime risk that is a possibility of dying of a certain disease by environmental contaminants, is useful as an evaluation technique of EHIA. It is recommanded the decision-makers to make efficient use of EHIA not only the development projects but also legislative proposals, policies and programmes in future.

  • Purpose: As an environmental concern increases, customers pay more attention to purchase organic food. While customers' purchase intention of organic food has been widely studied, there are lacks of researches regarding the moderation effect of environmental concern and the interactive effect of level of education based on the Theory of Planned Behavior (TPB). This study examines the influence of level of education and environmental concern on purchase intention based on the Theory of Planned Behavior and organic food in Vietnam. Research design, data and methodology: The methodology of mixed methods of qualitative and quantitative is applied with a survey of 420 customers being conducted to collect data from three biggest cities in Vietnam: Ho Chi Minh, DaNang and Hanoi. SPSS 23 and SMART-PLS 3.2 are used for data analysis. Results: The result shows that the customers have more environmental concern which increases their attitude to the intention of purchasing organic food. Moreover, there has not the three-way interactive effect of level of education, environmental concern and attitude on purchase intention toward organic food. Conclusions: This enriches the existing literature with the moderation of environmental concern to the relationship between attitude and purchase intention toward organic food in Vietnam based on the Theory of Planned Behavior.

  • (Most companies that perform BPR have not achieved satisfactory results or have not performed successful BPRs. There are many reasons for this, but the most important one has caused problems that do not accurately reflect the requirements of various stakeholders. In this paper, we will apply the BPR consulting methodology to a new value innovation requirements engineering process based on the Blue Ocean strategy, which is a way to create a new market without competition by customerizing potential customers by satisfying new customer expectations and needs. This paper uses a requirements engineering process that can generate customer value by applying the ERRC(Erasure Reduce Raise Create) analysis method, which is the core of the Blue Ocean Strategy Framework[1,2]. We will also apply the Six Sigma DFSS (Design For Six Sigma) methodology to improve quality and process through quantitative and systematic analysis. The proposed approach was presented to the BPR consulting to present a practical case, and the results of the empirical analysis of the system user to validate the results of BPR consulting.

  • The purpose of this study was to determine the possibilities of Korean fermented sauces including red pepper paste, soybean paste, soy sauce, and vinegar as ingredients for Western cuisine. Western cuisine professionals from US and Europe were interviewed for their experienced opinions. To classify the categories, the selected statements were given to other groups of foreign chefs, Korean cuisine professionals and students majoring culinary arts. The first category pointed out that Korean fermented sauces are healthy with 'umami' taste using only natural ingredients. They believe it has high possibilities of matching with many of other foods and also has unique tastes. Korean cuisine professionals were mostly occupied in this category. The second category had negative opinions matching with Western cuisines since Korean fermented sauces are rough and have a strong taste & smell. This category had many Western cuisine professionals. The last category was composed of mainly students majoring in culinary arts. They pointed out that Korean fermented sauces use natural ingredients and have a unique flavor with long-term shelf life. Use of Q methodology was significantly different from previous studies researched by quantitative methods especially for the Korea food service industry.

  • The number of young children who attend daycare center, preschool or kindergarten and are taken care of by teachers during a day has skyrocketed in Korea. The purpose of this study was to analyze the contents of the research on infant/child-teacher attachment in Korea. Thirty five studies (5 doctoral dissertations, 24 masters' theses, and 6 academic journal articles) published from 1993 to 2010 were analyzed in the matter of the publication period, the related variables, and methodology for analyzing the data. The findings are as follows: 1) More than two-thirds of the research were from masters' theses. The number of studies conducted in the late 2000s doubled compared to that in the 1990s. 2) Each study on infant/child-teacher attachment had at least one related variable regarding social, emotional, cognitive or physical development, but not language. The studies on infant/child-teacher attachment related to social development have rapidly increased in the late 2000s. 3) The majority of studies were conducted using quantitative analyses and Attachment Q-set version 3.0. Difference analysis and relational analysis were most frequently used in many studies. There was only one study which was analysed with the advanced statistical methodology. The implication for a future study was also discussed.
