UV-Spectrophotometer를 이용한 에너지 음료에 함유된 피리독신 함량의 비교 분석
이혜리, 권효식 충북대학교 과학교육연구소 2017 과학교육연구논총 Vol.32 No.2
These days, it's easy to see the students drink and energy drink called beverage for the 'test drinks'. The energy drinks are known as helping people to concentrate on their works and to overcome the fatigue. They are very popular among the twenties to thirties as well as teenagers. The consumption of the energy drinks led by Redbull and Hotsix emerged in the market in 2010 and has soared continuosly. The increasing interest in energy drinks has brought the preceding research on the danger caused by the caffeine. Exept the caffeine, however, the amount of the vitamins contained on them has been ignored. Therefore, the test, focused on the pyridoxine, vitamin B6, has neem designed to compare the amount of it contained the energy drinks using the UV-spectrophotometer. After making the standard solution of pyridoxine, the standard curve is dawn by the absorbance measure through the UV-spectrophotometer. The absorbance of pyridoxine will be measured several times under the same condition putting the selected four drinks, Hotsix, Hotsix-grapefruit, Guronsan bamond G, which can make ot possible to analyze and compare the amount of the pyridoxine in each energy drink.

Vulvar hematomas are uncommon outside of the obstetric population and may be the result of trauma to the perineum. Vulvar hematomas most often present with low abdominal pain and urologic and neurologic symptoms. The vulva has rich vascularization that is supplied by the pudendal artery, a branch of the anterior division of the internal iliac artery. We describe a rare case of a 15-cm-sized vulvar hematoma with the suggested rupture of a pseudoaneurysm of the left pudendal artery without trauma injury. A 14-year-old girl presented with sudden pain and swelling in her left labium and was successfully treated with selective arterial embolization and surgical evacuation. We provide a literature review and discuss patient treatment and management strategies.

Aphis gossypii was widely distributed throughout the tropical, subtropical and temperate zone. The chemical control of A. gossypii is becoming problem because it was rapidly appeared resistance expression to chemicals. We will attempt to resolve the this problem using RNAi technique. Besides, RNAi technology can be helpful to study the target genes of A. gossypii. In this study we produce cDNA library construction using gateway cloning system for selecting target gene in order to control of A. gossypii using RNAi. As a result, the 100-400bp of insert size, which is appropriate for RNAi was confirmed. Most of insert gene is associated with A. gossypii, after that insert sequence was compared with DNA databases and EST databases using NCBI blast search. Consequentially, A. gossypii of cDNA library with the titer of 3.15x105 clones were completed. And we will perform the LR recombination to transfer cDNA library into TRV2 (tobacco rattle virus) vector with att site. Then, after performing transformation using Agrobacterium tumefaciens (GV 2260), we inoculated to cucumber with A. tumefaciens. An insecticidal effect or a repellent activity against A. gossypii by changing behavior in transgenic cucumber plants were conformed. Also, the selecting target gene in order to control A. gossypii using RNAi may be provided.

Several species of the genus Aphidius are used in biological control programs against aphid pests throughout the world and their behavior and physiology are well studied. But despite knowing the importance of sensory organs in their behavior, their antennal structure is largely unknown. In this study, the external morphology and distribution of the antennal sensilla on the antennal of both female and male adults of A. colemani were described using scanning electron microscopy (SEM). Generally, the filaform antennae of males (1,565.60± 194.64㎛) are longer than females (1,303.83±156.41㎛). Antennae of this species is made up of scape, pedicel and flagellomeres. Male and female antennae differed in the total number of flagellomeres as 15 in males and 13 in females. Female and male antennae of A. colemani has samely ten types of sensilla. We classified 3 types of sensilla trichodea as without pores, with a tip pore and with wall pores, 3 types of sensilla coeloconica, 1 sensilla placodea and 1 Bohm bristles. In addition, the possible functions of the above sensilla types are discussed in light of previously published literature; mechanoreception (Bohm bristles and sensilla coeloconica) and olfaction (sensilla trichodea and sensilla placodea). Future studies on the functional morphology of the antennal sensilla of A. colemani using transmission electron microscopy (TEM) coupled with electrophysiological recordings will likely confirm the functions of the different sensilla identified in this study.

Male and female antennae differed in the total number of flagellomeres as 15 in males and 13 in females. Female and male antennae of A. colemani has samely seven types of sensilla. We classified sensilla placodea, Bohm bristles, 2 types of sensilla coeloconica, , 2 types of sensilla basiconica as with a tip pore and with wall pores, sensilla trichodea. In addition, the possible functions of the above sensilla types are discussed in light of previously published literature; mechanoreception(Bohm bristles, sensilla coeloconicaⅡ and sensilla trichodea) and chemoreception(sensilla coeloconicaⅠ, sensilla basiconicaⅠ,Ⅱ and sensilla placodea). Future studies on the functional morphology of the antennal sensilla of A. colemani using transmission electron microscopy (TEM) coupled with electrophysiological recordings will likely confirm the functions of the different sensilla identified in this study.

본 논문은 기존의 단순 감지 센서형 양식장 관리 시스템을 벗어나기 위해 IoT와 AI기술을 이용한 무인 양식장 관리 시스템 개발에 관한 것이다. 국내 양식장 상황에 맞는 유해 조류와 한국형 어선 이미지를 학습시켜 실시간 카메라 영상을 통해 유해 및 무해 물체를 판단하도록 하였으며 이에 따라 적절한 퇴치 기능을 수행하도록 하였다. 또한 현존하는 양식장 관리 시스템이 환경 관리 시스템과 감시 및 퇴치 시스템으로 이분화 된 경향을 보여 하나로 통합하는 과정의 필요성이 대두되었다. 따라서 감시 및 퇴치 기능 수행뿐만 아니라 양식장 내 환경 데이터를 실시간으로 받아오고 사용자가 단말기를 통해 양식장 상황을 확인 및 관리가 가능하도록 구현하고자 하였다.

Recently, the rate of cultivation of such as hairy vetch was increased as a way of reducing the current soil problem. However, the occurrence of insect pest such as bean bugs, Riptortus pedestris, were increased in the field of green manure crops and their injuries to hairy vetch were observed. While minimizing insecticide use for the environmental friendly agriculture, the control of the bean bug can be utilized environmental friendly agricultural materials (EFAMs) in the green manure crop fields. The control effects of some EFAMs and most of chemical insecticides to the bean bug were significantly high. As a result of direct spray of EFAM that contained sophora extract or neem extract, the control effects of six EFAMs were higher than 70% at 120 hours after treatments. Among them, three EFAMs were showed over 90% of control effects. On the other hand, most of chemical insecticides were showed 100% of control effect against the bean bug at 48 hours after treatment. As mortality effects of EFAMs were sloely observed until 120h after treatment, we must use selected EFAMs at the beginnibgs of occurrence and entrance in the field of green manure for effective control of bean bugs.
EPG를 이용한 담배가루이(Bemisia tabaci)의 섭식행동과 Cyantraniliprole에 대한 섭식변화
권혜리(Hye-Ri Kwon),윤영남(Young-Nam Youn) 충남대학교 농업과학연구소 2014 농업과학연구 Vol.41 No.2
Feeding behaviors of the sweet potato whitefly, Bemisia tabaci, and changing of their feeding behaviors were recorded and analyzed with an Electrical Penetration Graph (EPG) analysis against cyantraniliprole. The characteristic patterns of feeding behaviors investigated were as follows; NP (non probing), pathway phase waveform, waveform of feeding xylem. In results, B. tabaci did not almost feeding the phloem. And It was not appeared potential drop during recording time. It was predominantly indicated pathway activity waveform and waveform of xylem feeding. After treatment of cyantraniliprole with recommended concentrations to tomato plants, EPG waveforms were recorded during 3 hours. Cyantraniliprole treatment showed longer time to first feeding xylem than untreated (P=0.043). It was showed shorter duration of first feeding xylem than untreated (P=0.017). And it was showed longer NP (non-probing) time than untreated. Consequently, It was supposed that cyantraniliprole was effect of anti-feeding or avoidance to B. tabaci.
