The aim of this study is to assess the social value of Ham-Pyung Butterfly Festival in the year of 2011. The tool for the assesment is the zonal travel cost method. The result of the study can be summed up as follows; First, the average individual consumer's surplus measures approximately from 29,700 to 30,100 Won. Second, the total consumer's surplus, that is the social value of the festival, ranges approximately from 7.6 to 7.7 billion Won. The most beneficiary of the event is turned up to be the people who are living in the outside of Ham-Pyung and go on a tour there. For that reason, the central government looks to have the obligation to support and to sponsor the festival.

Microplastics with a size of less than 5 mm have emerged as an important environmental and food safety issue, as they have been detected not only in marine but also in terrestrial ecosystem and drinking water. Although many studies have been conducted on the exposure of microplastics and the effects on human health, the lack of standardized experimental methods for microplastics has been reviewed as a major problem. In order to overcome this, European countries such as the Netherlands and Germany are conducting a project to develop detection methods for microplastics as well as to establish the risk assessment methodologies for microplastics. Being the microplastics suggested to have a substantially potential risk on human health, reliable risk assessments should be conducted considering the various sources of microplastics, chemical pollutants and biological factors. In addition, international standards and regulations should be applied.

In order to present the scientific information of organic emissions from consumer products available, the current study examined the emissions composition for three different types of consumer products being used in Korea in an environmental chamber: air freshener (AF), mosquito repellents (MSQR), and moth repellents (MTHR). Emission rates were evaluated by determining emission rates of the target compound from the selected products using an electropolished stainless steel (SS) test chamber $(40{\times}25{\times}50cm^3)$. A time-dependent empirical relationship developed in this study agreed well with the test results. As same with the emission concentrations, MSQR exhibited the highest emission rate for all target compounds except for limonene and naphthalene. MTHR ($9,200\;{\mu}g\;h^{-1}$) showed the highest emission rate of naphthalene followed by MSQR ($8,300\;{\mu}g\;h^{-1}$). Moreover, the concentrations in residential bedroom conditions for target compounds emitted from three types of consumer products were estimated. This estimation suggests that the uses of consumer products can elevate indoor levels of target compounds. In particular, any types of the consumer products may increase the indoor level of m, p-xylene.

This study examined consumer perceptions towards outdoor wear differentiation and product attributes for outdoor wear differentiation to develop an outdoor wear differentiation strategy. It also investigated how consumer's evaluated product attributes according to consumer's demographic characteristics. Data were acquired from a survey of 454 adult respondents aged over 20 that was analyzed with descriptives, frequency, t-test, one-way ANOVA, factor analysis, and reliability. The results were as follows. First, it showed that consumers did not have a positive or a negative perception toward outdoor wear differentiation, and they thought outdoor wear should be differentiated. Those married and older tended to think that outdoor wear should be differentiated more than that for those single and younger. Consumer evaluations were significantly different on the necessity of outdoor wear differentiation according to age and total income. Second, consumers assessed that color, pattern and textiles had similar characteristics among outdoor wear brands; in addition, brand recognition and brand image had very different characteristics. Third, product attributes for outdoor wear differentiation were service and store, product quality, brand and popularity, and product designs with mean values of product quality, product design, service and store, and brand and popularity, respectively. Fourth, consumers were significantly different in the importance assessment of product attributes for differentiation according to gender, marital status and age.

최근 가습기살균제 사건을 비롯하여 휴대폰, 유아용 기저귀 등 생활용품의 안전사고가 빈번히 발생하고 있다. 이러한 사고로부터 소비자를 보호하기 위해서는 제품 안전관리가 필요하며, 제품의 안전성 정도를 평가할 수 있는 제품 리스크 평가 도구가 필요하다. 본 논문은 한국소비자원의 제품 사고관련 위해정보를 바탕으로 제품 리스크를 평가할 수 있는 시스템인 RAS(Risk Assessment System)를 구축하였다. RAS는 사고관련 정보를 분석하는 위해정보 분석시스템과 이 시스템으로부터 도출된 정보를 활용하여 리스크를 평가하는 리스크 평가시스템으로 구성되어 있다. 리스크 평가과정에서 제품 리스크에 영향을 미치는 인과관계를 반영한 베이지안 네트워크 기반의 확률적 기법을 적용하였다. RAS를 사용하여 어린이 제품 33품목에 대해 평가를 실시했으며 EU RAPEX의 RAG의 평가결과와 비교해 보았다. 그 결과 본 연구의 RAS의 결과는 전반적으로 EU RAPEX RAG의 평가 결과에 비해 낮은 수준을 보임을 알 수 있었다. 추후과제로는 사고영향척도 입력값의 주관성 저감, 위해정보 분석시스템과 리스크 평가시스템의 연동 등을 들 수 있다.

After incoming the notion of eco-friendly building, many organizations developed green building assessment programs and in the late of 2001, those programs were unified to one program, 'Green Building Certification(GBC)'. Many problems, however, arose after unification of programs and now the study to solve those problems is impending. The purpose of this study is to make suggestions to solve problems of GBC through analyzing characteristics of several abroad and well developed programs. The key points of the analysis were 1) characteristics of assessment organizations, 2) structures of programs, and 3) characteristics of assessment methods and systems. The results of the study showed that GBC didn't have any positive connections with the academia, the developer and the consumer, and did have lack of assessment efficiency and accuracy.

Freshwater fish intake is a critical parameter for deriving water quality criteria and water quality standards for protection of human health based on human health risk assessment. Although the freshwater fish intake parameter should be accurate and representative of Korean fish consumption for the water quality criteria to be reliable, data are limited in Korea and have low reliability. In this study, Korean National Health and Nutrition Examination Survey data from 2008-2010 were analyzed to reevaluate freshwater fish consumption. Based on these results, an average consumption rate of 3.0 g/day per person, a $90^{th}$ percentile consumption rate of 0.0 g/day per person, an average consumption rate of 65.7 g/day per fish consumer, and a $90^{th}$ percentile consumption rate of 153.4 g/day per fish consumer were proposed for derivation of water quality criteria using a conservative approach and various exposure scenarios.

선진국에서 유해물질을 함유하는 소비자 제품의 위해성 관리를 위해 CONSEXPO등의 다양한 소비자 노출평가 모델을 개발하여 소비자 제품에 함유된 유해화학물질의 노출로 인한 위해도를 평가하고 이를 규제 기준의 설정근거로 활용하고 있다. 이에 본 연구에서는 다양한 시나리오에 적용할 수 있는 노출평가 모델을 검토하고 대상 제품을 선정하여 적정 모델을 적용하여 위해성 평가 단계에 따라 위해성 평가를 하여 제품 별 위해성 평가 기법을 마련하고자 하였다. 작성된 노출 시나리오를 바탕으로 노출 계수를 선정한 뒤 CONSEXPO 노출평가 모델을 기반으로 하여 알고리즘을 작성 한 결과 프탈레이트류의 경우 일부 장판에서 전이량이 검출되었으나 함량과 전이량의 상관관계를 살펴본 결과 r-square 0.0065으로 상관관계가 거의 없는 것으로 나타나, 이 결과를 기준으로 함량 기준값을 산출하는 것은 무리가 있다고 사료되며 현행제품기준을 유지하는 것이 무방할 것으로 판단된다. 휘발성유기화합물 또한 인체에 유해하지 않은 것으로 나타났으므로 현행 기준을 준수 할 경우 큰 무리가 없을 것으로 것을 판단, 새로운 기준을 제시 하지 않았다. 중금속의 경우 전이량이 검출되지 않았으므로 위해성 평가는 수행하지 않았다. 따라서 경피노출로 인한 인체의 유해가능성은 매우 적을 것으로 판단할 수 있다.

The objective is to recognize the better opportunities from targeted reveal advertising, to show a banner ad to the consumer of online who is most expected to obtain a preferred action like signing up for a newsletter or buying a product. Discovering the most excellent commercial impression, it means the chance to exhibit an advertisement to a consumer needs the capability to calculate the probability that the consumer who perceives the advertisement on the users browser will acquire an accomplishment, that is the consumer will convert. On the other hand, conversion possibility assessment is a demanding process since there is tremendous data growth across different information dimensions and the adaptation event occurs infrequently. Retailers and manufacturers extensively employ the retail services from internet as part of a multichannel distribution and promotion strategy. The rate at which web site visitors transfer to consumers is low for online retail, out coming in high customer acquisition expenses. Approximately 96 percent of web site users concluded exclusive of no shopper purchase[1].This category of conversion rate is collected from the advertising of social media sites and pages that dataset must be estimating and assessing with the concept of big data clustering, which is used to group the particular age group of people along with their behavior. This makes to identify the proper consumer of the production which leads to improve the profitability of the concern.
