It has continuously promoted to scale up the agricultural management body in order to cope with the market-opening pressure such as the UR negotiation, the DDA negotiation, and more conclusions of FTAs and to enhance the competitiveness of our agriculture. This study evaluated the factors associated with production organization participation centered on environmentally-friendly agriculture farmers in order to improve the production efficiency of environmentally-friendly agriculture in the aspect of production. In order to achieve this objective, this study evaluated the factors that contributed to participating in an organization using the bivariate probit model focusing on environmentally-friendly agriculture farmers in Chungnam. This study examined the validity and reliability of the study model through exploratory factor analysis. The results of factor analyses identified four factors: “distribution”, “production”, “organization operation”, and “social capital”. The results of the bivariate probit model showed that distribution significantly affected production activities and distribution, organization operation, agricultural income, and gender significantly influenced sale activities. Environmentally-friendly production organization had not been able to provide the productive support that was needed for local farmers to produce environmentally-friendly agricultural products in a region. Additionally, farming education did not provide the information needed by the farmers. Although producers had a network within a production organization, it was operated mainly for administrators. Therefore, participants felt somewhat lacking. This study identified the level of organization of producer organizations in Chungnam area, where environmentally-friendly agriculture is well activated. This study suggested implications for future production organization participation by evaluating factors affecting participation quantitatively.

Many consumers intend to make environmentally purchase. However, this is not always what occurs. A gap exists between consumer intentions to purchase environmentally friendly products and their actual purchase behavior. In this study, we examined the effect of situational factors such as price sensitivity, product quality perception, and label trust on the relationship between purchase intention and purchase behavior for environmentally friendly products. First, we conducted a theoretical consideration through a review of literature on price sensitivity, product quality perception, label trust, purchase intention and purchase behavior. Based on the literature review, we designed a structural model and developed the hypotheses. Next, we collected data using a survey and processed them statistically in order to verify the hypotheses. A total of 213 samples were collected and the data were analyzed using a structural equation model (LISREL 8.70). The results suggest that the situational factor of label trust has a moderating effect on the relationship between purchase intention and purchase behavior for environmentally friendly products. However, price sensitivity and product quality perception have no moderating effect. This means that trust in labels is important when consumers want to buy environmentally friendly products. Although this study has some limitations, it is expected that it will positively trigger follow-up research.

Phytoplankton populations were examined at three sites in Lake Cheongpyeong, South Korea from March 2008 to December 2016, including measurement of phytoplankton communities and their dominant species, abundance and environmental factors. The annual average ranges of water temperature, dissolved oxygen and conductivity were 15.2-18.8℃ , 10.3-12.2 mg/L, 86-140 μS/cm, respectively, with similar values at all studied sites. The highest phytoplankton cell density was observed in spring and fall, and it subsequently decreased rapidly during heavy rainfall. Diatoms were dominant in spring (mainly Stephanodiscus hantzschii, Asterionella formosa) and fall (mainly Aulacoseira granulata), while greenalgae and cyanobacteria had high appearance in early-summer and summer, respectively, indicating that water temperature is the most important factor influencing their growth. Stephanodiscus hantzschii and Asterionella formosa frequently occurred at low water temperature (4.5-15.0℃ and 5.4-21.6℃ , respectively) while Aulacoseira granulata and Anabaena spp. were favored by high water temperature (8.6-28.4 and 14.9-26.2℃ , respectively) and phosphorus. Additionally, Fragilaria crotonensis occurred at low nutrient conditions. Rhodomonas spp. frequently appeared year-round.

The concerns about potential risks and hazards in children’s playgrounds are increasing and the restrictions for environmental harmful substances in playgrounds have been reinforced in many countries. In this study, the concentrations of heavy metals were analyzed in 142 samples including 105 of sand flooring and 37 playing equipment such as swing, slide, sporting equipment, bench and fence in 18 children’s playgrounds. Heavy metals in sand flooring were investigated and categorized by natural environmental factors such as season, rainfall, post-rainy day, and artificial factors as road, type, and material of nearby play equipment. The concentration of heavy metals such as Pb, Hg, Cu, and Zn were significantly higher in sand flooring near the play equipment than at places away from the playing equipment (p < 0.05). Spearman’s rank correlation analysis showed that play equipment had a positive correlation with the sand flooring with regard to the concentration of Pb (r = 0.42, p < 0.01) and Cu (r = 0.39, p < 0.01). The concentration of heavy metals in the sand flooring showed a statistically significant difference depending on the season, post-rainy day, the distance from a roadway, type of equipment, and the material. The play equipment’s heavy metal concentration and other environmental factors contributed to the heavy metal concentration in the sand flooring’s surface in playgrounds.

We analyzed with HPLC (High Performance Liquid Chromatography) analysis photosynthetic pigments and environmental factors, microscopic observations of the phytoplankton and zooplankton in the seawater every month from February 2009 to November 2010 in Haengam Bay. The level of dissolved inorganic nutrients was the highest between July and September, when freshwater influx was at its peak, whereas chlorophyll a levels were the highest in April and August. Also, phytoplankton pigment concentration increased when dissolved inorganic nutrients are carried into nearshore waters by rainfall runoff. Based on identification of phytoplankton and photosynthetic pigments results, diatoms were mainly dominant while dinoflagellate populations increased at July and August 2009, May 2010. The zooplankton communities are dominated in terms of Noctiluca scintillans. The contribution of Noctiluca scintillans in 2010 accounts for approximately 77.3% of the total zooplankton. Distribution patterns over time of zooplankton in the seasonal distribution of phytoplankton showed a different pattern.

Durability and structural safety of steel structure are severely affected by corrosion caused by deicer material as well as by airborne chlorides in the marine environment. In this study, based on analysis of current status it is suggested that deterioration and durability reduction by the environmental factor such as chlorides should be more reasonably taken into consideration for the accurate inspection and condition evaluation of steel structures.

The environment-friendly agricultural product market receives consumers’ great interests despite relatively few studies focused on consumers’ decision making process of the environment-friendly agricultural products. This paper examines what factors influence on consumers’ attitude and buying behavior on the environmentfriendly agricultural product. In order to find the relative importance of each factor’s influence, this study adopts multiple regression method based on the survey results of 500 people with the systematic random sampling. The results showed that consumers’ favorable attitude towards the environment-friendly agricultural product were influenced by taste, freshness, food safety, and positive attitudes toward the environment-friendly agricultural product promotion. In addition, consumers’ purchase intention was influenced by taste, food safety, environmental concern, and the promotion. Respondents recommend the environmentfriendly agricultural product when they believe that the environment-friendly agricultural product had the values of taste, environmental concern, and promotion. Women are more active in buying and recommending the environment-friendly agricultural product; however, the price was not the statistically meaning factor. This study provides empirical data that was used for marketing and increasing the sales of the environment-friendly agricultural product. Future research was advised to examine more thoroughly on the relationships between the promotion efforts and purchase intention and the occasions when the price becomes the issue in the buying decision of the environment-friendly agricultural product.

This study was carried out to determine marine environments and phytoplankton community in Deukryang Bay during the period of summer in 1987-2010. Water temperature, salinity, pH and dissolved oxygen were shown in much yearly fluctuations. In August, water temperatures in surface and on bottom were the highest, compared with average surface (24.54℃) and bottom (22.90℃) water temperature for 18 years in Deukryang Bay. The main reason is assumed to longer duration of sunshine during the period of August. Although the amount of the rainfall in August was the highest, significant impact of marine environment did not show. Most of dissolved inorganic nitrogen and phosphate in Deukryang were lower concentration during summer and N:P ratio also showed below 18 in Redfield. In particular, extreme increasing of N:P ratio in August was occurred by intensive precipitation. Distribution of phytoplankton community was a consistent occurrence for 18 years. The genus of Chaetoceros, Cosinodisucs and Skeletonema were regarded as the represent diatom, whereas the highest occurrence of genus among dinofagellates was Ceratium. It is thought that the relationship between phytoplankton and nutrient has a strong positive signal, although nutrients persist a little concentration and much fluctuations in marine environments were observed. High availability in phytoplankton is contributed to consistently provide the food organism of shellfish. Consequently, recent decreasing production of shellfish and seed are probably associated with higher temperature during the period of summer. However, higher temperature is also occurred ago and after 2000. On the basis of geography, Deukryang Bay had a small mouth and long channel, which is attributed to decreasing genetic diversity. It is assumed that higher temperature and lower genetic diversity have a extreme impact of larvae and shellfish for reproduction in Deukryang. It is necessary to persistently monitor based on water quality and phytoplankton community.

오늘날의 다양한 교육환경 속에서 교사의 역할과 책임은 날로 그 중요성이 커지고 있다. 많은 학자들이 교사의 교육 행동에 영향을 미치는 중요한 요인으로 교사효능감을 꼽고 있다. 따라서 교사효능감에 영향을 미치는 직무환경 요인을 조사하여 영향력을 알아보는 것은 컴퓨터 교사의 교사효능감을 증진시키는 방안을 모색하는데 큰 도움을 줄 것이다. 본 연구에서는 컴퓨터 교사 170명을 대상으로 설문조사를 실시하였다. 직무환경을 물리적 환경, 수업외 환경, 구조적 환경은 컴퓨터 교사의 교사효능감에 유의한 영향을 주는 요인으로 밝혀졌으며, 이 중 행정체제의 운영 과정과 교직원간의 의사소통의 질, 직무 수행 중에 허용되는 자율성의 정도 등에 대해 교사가 지각하고 있는 정도를 의미하는 구조적 환경이 교사효능감에 가장 많은 영향을 주는 요인으로 드러났다. 따라서 컴퓨터 교사의 교사효능감을 향상시키기 위해서는 컴퓨터 교사의 효율적인 교육활동을 위한 근무 여건을 개선하고, 학교관리자와 교사간의 우호적 관계를 형성하며, 교사의 의견이 자유롭게 반영될 수 있도록 유연한 직무환경을 마련하는 것에 큰 관심을 가져야 할 것이다.
