The appearance and physicochemical characteristics of a native jujube (called Yak jujube) and Bokjo jujube were compared in this study. Our results revealed that the native jujube had smaller size, lower hardness, and higher contents of sugar, crude protein, crude fat, crude ash, dietary fiber, and calcium contents, when compared to that of Bokjo jujube. Therefore, native jujube is softer and sweeter, with higher general nutrient content, despite being smaller than that of Bokjo jujube.

Hydrometallurgical process, which is one of the recycling method of EAFD in zinc, is a process to recover metallic crystal form that deposited on the cathod through electrolytic extraction by leaching valuable metals in appropriate solvent. Still, there is a lot of variable at electrowinning process, such as initial pH, space between electrode, voltage, current, cathod, or anode, Thus, many studies have been conducted previously. In this study, the consideration of optimistic condition in electrowinning process to recover the valuable metal in EAFD have been carried. The extraction amount by changing pH shows increase according to high initial pH, also, the alteration of extraction amount by controling the space between electrode, voltage or current has been measured. The difference of efficiency represent by decrease of electromotive force, sudden loss of voltage under specific condition, and using platinum as electrode shows most stable extraction. Furthermore, when distance between electrode are too close, the extracted zinc contact with anode, which make recovery difficult. The analysis result of zinc metallic crystal which been recovered draws spherical and cylindrical shapes are scattered and mixed, and consequence of EDX, content of zinc appear about 60%.

본 연구에서는 긍정의 말과 의도가 애기장대의 발아와 생체중에 미치는 영향을 알아보았다. 매번 200개의 애기장대 종자를 4개의 묘판에 각각 50개씩 파종하였고 이를 3차례 반복 실험하였다. 10개의 긍정적인 말과 부정적인 말을 개발하여 사용하였으며, 사람의 음성과 기계음(test-to-speech software, Voice TestTM)을 통해 각각의 말을 애기장대 종자에 들려주었다. 또한 사람의 의도가 종자에 미치는 영향을 알아보기 위해 실험자로 하여금 부정적인 말은 부정적인 의도를 가지고, 긍정적인 말은 긍정적인 의도를 가지고 읽게 하였다. 긍정적인 말과 부정적인 말, 그리고 의도는 발아율에 유의미한 영향을 주지 않았다. 그러나 평균 생체중 비교에서는 의도가 있는 사람의 긍정적 말이 애기장대의 생체중 증가에 유의하게 영향을 주었다. 따라서 애기장대에 긍정적인 의도를 포함하여 긍정의 말을 전달하였을 때 애기장대의 생체중에 크게 구별되는 효과가 있다는 점을 알 수 있다.

This study, the changes in physicochemical properties and hesperidin content of Jeju-processed citrus fruits according to the harvest date were evaluate. The soluble-solid content, pH, and soluble solid-acid ratios gradually increased , but titratable acidity slightly decreased with a delay in the harvest date. The color index, lightness, yellowness, and turbidity slightly decreased whereas the redness slightly increased with a delay in the harvest date. The hesperidin content slightly decreased with a delay in the harvest date. Hesperidin, which is the major cause of juice cloudiness, decreased with a delay in the harvest date. These results suggest that later-harvested fruit juice is bound to be less cloudy.

Phenotypes of panicle, hull and seed of mutant rice (Oryza sativa L.) were characterized. Panicle mutants were classified in 4 groups with their internode length of main rachis, primary rachis, secondary rachis and pedicel. Hull and seed mutants were grouped into 12 based on their mutant characters in shape, size and color of seeds. These natural and spontaneous mutant collections showed distinct phenotypes to wild type rice. This might be useful for the identification of the functions of genetic factors in the Mendelian inheritance.
