High temperature stress in summer season at plastic house is a limiting factor for tomato fruit set andyield. This study was performed to assess the effects of gibberellic acid (GA3) and 2,4-Dichlophenoxy acetic acid(2,4-D) spray on fruit set, yield, and quality of tomato cv. ‘Adoration’(Enza Zaden Co., Ltd.) under the plastic housein Hwacheon, 2011. Four concentrations (0-, 5-, 10- and 15mg·L−1) of GA3, and three concentrations (0-, 5- and10mg·L−1) 2,4-D were sprayed in early flowering of tomato in the plastic house, and fruit set, yield and quality characterswere observed. The results showed that spray of 10mg·L−1 GA3 significantly increased the fruit set by 14.2%than unsprayed. The spray of GA3 significantly increased the marketable fruit number, fruit weight, and yield. Thespray of 2,4-D on blossoms significantly affected the fruit set percentage, fruit weight, marketable fruit weight andyield, and the highest fruit set observed as 62.5% in combined spray of GA3 and 2,4-D at each 5mg·L−1. Fruit sizeand total soluble solids significantly varied with the concentrations of GA3 sprayed. The result indicates that thespray of 10mg·L−1 GA3 and 5mg·L−1 2,4-D can be more economic and effective to increase the fruit set, and yield intomato under high temperature condition in plastic house.

Polystyrene is cross-linked to generate micropores for sorption applications. Herein, we report for the first time, hypercross-linking of polystyrene in the presence of Friedel-Crafts catalyst, FeCl3 without a cross-linker. For comparison, polystyrene was also hypercross-linked with a cross-linker, dimethoxy methane with the same catalyst. The cross-linking and de-hydrogenation of cross-links to quinonoid formation were confirmed by FT-IR and 13C-NMR techniques. The hyper cross-linked polymers (HCPs) were also characterized by TGA, DRS-UV, SEM, BET and CO₂ sorption techniques. All the HCPs showed a maximum of 5 weight % CO₂ sorption at 25 °C and 1 atm. The same polymers could also be applied for the sorption of other air pollutants.

Overusing chemical fertilizers involves potassium accumulation in the soil, which can become a toxicity problem in agriculture. This study was conducted to investigate the effect of potassium (K) treatment on growth, physiological characteristics, and morphological changes using Chinese cabbage (Brassica rapa L. ssp. campestris). With high (600 mM) K treatment, the plant growth traits of leaf length, leaf area,and fresh and dry weight of shoots and roots decreased, whereas chlorophyll content increased. As the concentration of K increasing, total N, P, and K increased in leaves, but concentrations of Ca, Mg, and Na decreased. However, Mn, Fe and Zn contents were highest in 100 mM K treatment. Chlorophyll a, b, and carotenoids increased with increasing K concentration. Maximum photochemical efficiency (Fv/Fm) was not significant in the all treatments, whereas CO_2 assimilation decreased with increasing K level due to stomatal degradation. Total free amino acids increased with the 10 and 100 mM K but decreased at 600 mM K treatments. Therefore, the growth and physiological characteristics of Chinese cabbage ascertained that tolerance up to 100 mM K when grown with nutrient solution in pot culture.

Phytoplankton forms the base of sea ecosystems. Various environmental factors and anthropogenic pollution, primarily, affect the concentration and photosynthetic activity algal cells, and the changes in the phytoplankton photosynthesis influence other elements of aquatic ecosystems. The increase in anthropogenic pollution markedly damages natural aquatic ecosystems, particularly, in the coastal zones, where an intense blooming of microalgae occurs, including the release of highly dangerous ecotoxic substances of various chemical natures (red tides). In this study, we tried to apply as a parameter for the algal blooming prediction in the ocean from fluorescence values in the taken samples around Busan coastal area. F0 value was almost constant but Fv/Fm value showed the irregular pattern. We presume that these results are due to the changes of the ocean environment and climate. To predict or give early warning the algal blooming, we need to investigate the specific area or fixed area through real-time monitoring. Especially, algal blooming prediction or warning can be achieved via continuously monitoring and interpretation of fluorescence changes.

Traditionally, like many people in mountain region of the Himalaya, the Lwang communities depend on mix of subsistence agriculture, animal husbandry, and seasonal migrant labor for their livelihoods. These traditional systems are characterized by low productivity, diverse use of available natural resources (largely for home consumption), limited markets, and some aversion for innovation. The potential to generate wealth through commerce has largely been untapped by these mountain residents and thus is undervalued in local and national economies. Introduction of organic tea farming is a part of Lwang community's several initiatives to break the vicious poverty cycle Annapurna Conservation Area Project (ACAP) played facilitating roles in all their efforts since beginning. In five years, the tea plantation emerged as a new means for secured a livelihood. This study aims to analyze the current practices in tea farming both in terms of farm management and soil nutrient status(technical) and the prosperity of the tea farmers (social). The technical aspect covers the soil and tea leaf analysis of various nutrients contents in the soil and tea leaf. Originally, the technical aspect of the study was not planned but later during the consultation with the advisor it was taken into consideration which added value to the research study. The sample were collected from different locations and analyzed on the field itself. The other part of the study i.e. the social aspect was done through questionnaire survey and focus group discussion. the tea farming provided them not only a new opportunity but also earned an identity in the region. This initiative was undertaken as a piloting measure. Now that the tea is in production with processing unit established locally, more serious consideration has to be given for better yield and economic prosperity. This research finding will help the community to analyze their efforts and make correction measures in tea garden management and application of fertilizer. It is also expected to fill up the gaps of knowledge and information required to reduce economic stresses and enhance capacity of farmers to make the tea farming a sustainable and beneficial business. The findings are expected to Sustainability of organic tea farming has direct impacts on biodiversity conservation compared to the other traditional farming practices that are more resource intensive. The study will also contribute to identify key action points required for reducing poverty while conserving environment and enhancing livelihoods

본 연구는 칼륨의 독성에 따른 배추의 생육과 생리적 특성 그리고 형태적 변화를 관찰하기 위하여 수행하였다. 100mM의 칼륨 농도 처리구까지 전체적인 생육이 증가한 반면, 600mM 처리구에서 생육이 가장 저조하였다. 칼륨 처리 농도가 높을수록 N, P, K, 함량은 증가하였지만 Ca, Mg, Na 함량은 감소하는 경향을 보였으며 미량원소, Fe, Mn, Zn의 경우 100mM의 처리구에서 가장 높은 함량을 나타내었다. 생체중당 Chl a, b와 carotenoid 함량은 600mM에서 가장 많이 증가하였으나 증가한 엽록소 함량에 비해 광합성효율(Fv/Fm)은 처리구간에 차이가 없었고 CO₂ 동화율은 오히려 감소하였다. 이는 칼륨 과다에 의한 삼투스트레스의 결과로 기공의 퇴화와 CO₂ 동화능력과 밀접한 관계가 있는 것을 형태학적 관찰로 확인되었다. Total free amino acid의 경우 100mM 처리구까지 칼륨 처리 농도가 증가함에 따라 증가한 반면 600mM에서 급격히 감소하였다. 따라서 본 실험에서의 배추는100mM의 칼륨 농도까지는 긍정적인 효과가 있는 것으로 판단되었다.

Mesoporous Fe2O₃/TiO₂ was synthesized by sol-gel route using pluronic P123 the as structure directing agent. The mesoporous nature of the material was confirmed from low angle X-ray diffraction. The material was supported on reduced graphene oxide and characterized by FT-IR, Raman, XPS, N2 sorption, HR-TEM and SEM. The reduced graphene oxide supported Fe2O₃/TiO₂ nanocomposite was tested for the sorption of both As(V) and As(III) from aqueous solution. The equilibrium adsorption attained within fifteen minutes for both As(III) and As(V). The maximum adsorption capacity for As(V) and As(III) was found to be 99.5 and 77.7 mg/g at pH 6 and 7 respectively. The sorption was found to high in the pH range of 6-7.
