Social commerce is not only a new form of shopping malls that did not exist in the past, but also a new form of media as it gets combined with social networking services. The purpose of this study is to analyze the influence of clothing involvement on the relationship between shopping values, attitudes, and purchase intentions of consumers in the group-buying type of social commerce. A specialized Internet survey company carried out the survey targeting consumers in their 20s and 30s with experience of purchasing fashion products using group-buying type of social commerce. A total of 200 questionnaires were used for the final analysis. Descriptive statistics, factor analysis, t-test, and regression analysis were conducted by using SPSS 12.0 and AMOS 19.0. The results are as follows. First, diversity/informativeness, impulse/accumulation, price, convenience, reliability, interaction, and adventure were identified as shopping value dimensions. Second, especially in cases of diversity/informativeness, price, and interaction, there were significant differences between the high involvement group and the low involvement group. Third, five of the categories, which were diversity/informativeness, price, convenience, reliability, and interaction, had significant influence on attitude and purchase intention. When the attitude variable was included with shopping value as independent variables in the regression model to predict purchase intention, the attitude variable presented a full mediating effect or a partial mediating effect between shopping value and purchase intention. Also, the relationship among shopping value, attitude, and purchase intention was different to some degree according to the level of consumer clothing involvement.

This study examines the influence of product classification standards and structure on user perception as well as their attitude towards online shopping sites. The causal relationships of variables are also examined. The analysis was based on an online survey with 247 responses. Four types of internet shopping sites were developed and used as a stimulus. The results of the mean comparison analysis indicated that perceived variety, information overload, perceived shopping value and attitude towards the site varies significantly with product classification standards and structure. There was also of a marginally significant interaction between the classification standard and structure on perceived variety and information overload. The causal relationship analysis revealed that perceived variety positively influenced hedonic and utilitarian shopping value. However, information overload had a negative effect on hedonic and utilitarian shopping value. Both the hedonic and utilitarian shopping value positively influenced attitudes towards the sites. This study demonstrates that classification method influences customer perception and attitude. It offers interesting insights on a product classification method as a strategic tool for online shopping.

This study performs an investigative research on the shopping value of consumers who purchase fashion/beauty products using group buying social commerce among the types of social commerce and private shopping malls. We provide basic knowledge on consumer behavior using social commerce newly appeared as shopping channels. For the method, the research was performed by designing a sequential integration method of conducting quantitative verification after qualitative research. As a result of qualitative research, multiple shopping values have been shown as the common shopping values of consumers using two types of shopping malls. The dimensions are price, quality, convenience, interaction, information, reliability, hedonic and impulse buying values. A total of eight sub-dimensions have appeared due to performing quantitative verification on the shopping value of group buying social commerce. The dimensions are same as the results from the qualitative research. The shopping value of consumers who purchase fashion/beauty products using private shopping malls has been classified into seven dimensions (except interaction value).

발달장애인이 참여한 장애이해교육이 교육참여자에게 가지는 의미 탐색

지적장애인과 자폐성장애인은 그들의 지적능력과 의사소통능력의 부족으로 인해 발달장애로 분류되고 있으며, 발달장애인의 수는 전체 장애인 수의 감소와 달리 증가하는 추세이다. 또한 특수교육대상자의 2/3 이상은 발달장애인으로 다른 장애 유형에 비해 절대적으로 많은 수준을 나타내고 있다. 하지만 교육현장에서 발달장애에 대한 이해 부족으로 인해 또래학생으로부터 차별을 경험하고 있다. 그럼에도 불구하고 현재 교육 현장에서 실시하는 장애이해교육은 특수교육대상자의 다수를 차지하는 발달장애인이 아닌 감각장애에 대한 내용으로 주로 이루어져 있으며, 학령기 발달장애학생과 함께 생활하는 또래들과 교사들은 여전히 발달장애를 이해하지 못한 채로 머물러있다. 이에 본 연구는 발달장애인의 효과적인 사회 통합을 위하여 발달장애인 당사자가 참여하는 발달장애이해교육이 교육 참여자들에게 가지는 의미를 탐색하였다. 이를 위하여 아동과 교 사를 대상으로 인터뷰를 실시하여 이를 분석하며 의미를 발견하는 질적연구방법을 활용하였다. 그 결과, 교육에 참여한 또래 학생들과 교사들은 발달장애인 당사자와 소통할 수 있는 ‘의미 있는만남’을 통해 발달장애인을 이해하지 못함으로 인해 학급 내에서 겪던 갈등을 해소하고, 서로에게 긍정적인 이미지를 전달하며 상호 성장하고 있었다. The developmentally disabled are being categorized as those with developmental disability due to their lack of intellectual capacity and communication ability, and their number tends to increase in spite of the decrease of the number of the disabled on the whole. In addition, more than 2/3 of the targets for the education for the handicapped are the developmentally disabled, so their number is absolutely bigger than that of other types of disability. Nevertheless, the education conducted in the education field to help understand the disabled is about sensory disability rather than about developmental disability consisting of most of the targets for the education for the handicapped, and they still remain incomprehensible to their classmates and teachers. Accordingly, this research examined the meanings of disability awareness education which the developmentally disabled had joined to the participants for effective inclusion of the developmentally disabled to the society. To accomplish this goal, children, and teachers were interviewed, and it was found out that the participants in the education had ‘meaningful encounter’ with the developmentally disabled themselves, through which they could dissolve conflicts resulting from misunderstanding, deliver positive images one another, and improve themselves together.

Concentrations and sources of precursor gasses (NH₃, SO₂, NO<SUB>x</SUB>) and PM<SUB>2.5</SUB> at a commercial manure composting facility

Livestock manure is an important source of ammonia emissions globally, contributing to poor air quality through the formation of secondary inorganic aerosols. As per capita meat consumption increases, concentrated animal feeding operations (CAFOs) have become increasingly common, leading to large quantities of excreta that need to be treated in dedicated manure processing facilities. However, little is known about the scale of gaseous emissions from these facilities, and the potential impact they have on air quality and the surrounding environment. This paper presents NH<SUB>3</SUB>, SO<SUB>2</SUB>, NO_x and PM<SUB>2.5</SUB> monitoring data from a modern commercial manure composting facility located in Paju, South Korea. During the five-week monitoring period during June – July 2020, average internal concentrations of NH<SUB>3</SUB>, SO<SUB>2</SUB>, NO, NO<SUB>2</SUB> and PM<SUB>2.5</SUB> were found to be 57.1 ± 1.3 mg m^-3, 307.2 ± 17.4 μg m^-3, 33.4 ± 3.2 μg m^-3, 7.3 ± 0.8 μg m^-3, and 36.9 ± 2.6 μg m^-3, respectively. The NH<SUB>3</SUB> emission rate was calculated to be 7.28 ± 0.41 NH<SUB>3</SUB>-N mg min^-1 m^-3, with scaled emissions rates of 1.85 ± 0.1 NH<SUB>3</SUB>-N g h^-1 m^-3 of manure compost, or 1.52 ± 0.09 NH<SUB>3</SUB>-N g kg^-1 of manure compost over the full 18-day composting period. The evidence suggests that the high-volume ventilation and scrubber system, maintaining a negative pressure environment inside the facility, was highly effective at limiting external emissions, and can be recommended as a suitable technology to reduce pollution from manure composting facilities.
