To determine host-related infochemicals that facilitate contact between the egg-pupal parasitoid, Fopius arisanus (Sonan), and its host, Bactrocera dorsalis (Hendel), we analyzed the volatiles on the surface of B. dorsalis eggs by hydrocarbon profiling of the hexane extracts using Gas Chromatography–Mass Spectrometry (GC–MS). These analyses resulted in the identification of 12 components from the egg surface. Among these 6 were alkanes (Dodecane, Heneicosane, Docosane, Tricosane, Tetracosane and Pentacosane) and the proportion was 42.79%, 1 was a fatty acid (Palmitic acid) and the proportion was 3.88%, 3 were fatty acid derivatives (Dodecanoic acid methylester, Lauric acid ethyl ester and Ethyl tetradecanoate) and the proportion was 45.92%, and 2 were alcohols (Tetradecanol and Hexadecanol) and the proportion was 7.41%. 9 chemicals were chosen from the above 12 components to study the EAG and behavioral responses of male and female F. arisanus. The results showed that the EAG and behavioral responses of F. arisanus to same chemical had similar trends, and both EAG relative values and lure rates of females were higher than males' generally. However, for Dodecane and Tetracosane the EAG relative values and lure rates showed extremely significant differences between males and females respectively, for Tricosane there was significant difference, for Ethyl tetradecanoate there was no significant difference between males and females of the relative EAG values but of the lure rates there was significant difference. The resultsmaybe provide new insights fromthe chemical relationship between parasitoid and host to biocontrol B. dorsalis using F. arisanus.

Extended kernel correlation filter for abrupt motion tracking

( Huanlong Zhang ),( Jianwei Zhang ),( Qinge Wu ),( Xiaoliang Qian ),( Tong Zhou ),( Hengcheng Fu ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.9

The Kernelized Correlation Filters (KCF) tracker has caused the extensive concern in recent years because of the high efficiency. Numerous improvements have been made successively. However, due to the abrupt motion between the consecutive image frames, these methods cannot track object well. To cope with the problem, we propose an extended KCF tracker based on swarm intelligence method. Unlike existing KCF-based trackers, we firstly introduce a swarm-based sampling method to KCF tracker and design a unified framework to track smooth or abrupt motion simultaneously. Secondly, we propose a global motion estimation method, where the exploration factor is constructed to search the whole state space so as to adapt abrupt motion. Finally, we give an adaptive threshold in light of confidence map, which ensures the accuracy of the motion estimation strategy. Extensive experimental results in both quantitative and qualitative measures demonstrate the effectiveness of our proposed method in tracking abrupt motion.

In the present study, preservatives and antibiotics were applied in a variety of doses to assess their effects on the beer waste-based protein bait, a product widely used to control populations of Bactrocera dorsalis (Diptera: Tephritidae). Screening was performed using the inhibition zone method against the dominant bacteria in deteriorated protein bait. Additionally, the attractiveness of the bait was assessed after respectively adding different doses of methyl eugenol, brown sugar solution, ammonium acetate, and guava essence, as determined by bio-cage tests. The results showed that the four selected preservatives had different inhibition effects at different dose levels, and that the level of inhibition increased with dose: at the highest dose of 1:1 (v:v), sodium benzoate can significantly inhibit Staphylococcus spp., potassium sorbate can significantly inhibit Lactobacillus spp., sodium nitrite can significantly inhibit Escherichia spp. and ethyl p-hydroxybenzoate can significantly inhibit Staphylococcus spp. and Xanthomonas spp. Among three antibiotics, kanamycin was the most effective in suppressing a mix of all four bacteria for all tested doses. In terms of lure performance, the addition of four substances in various ratios into the protein bait were found to have varying effects on its attractiveness to B. dorsalis females and males. Specifically, the addition of a high-dose of guava essence could significantly enhance the attractiveness of the bait. Our findings will help to enhance the effectiveness of protein bait ap plications by prolonging the quality guarantee period and improving its attractiveness toward both female and male B. dorsalis.

Co-60 radiation has been broadly used for pest management because it results in male sterility and a lack ofemergence of unparasitized hosts due to oxidative damage. Insect life is significantly affected by abiotic stressfactors, including Co-60 radiation. In the present study, we determined the influence of Co-60 radiation on animportant pest in southern China, the oriental fruit fly Bactrocera dorsalis (Diptera: Tephritidae). We exposed 30-h-old B. dorsalis eggs to Co-60 radiation at doses of (0, 5, 10, 15, 20, 25, 30, 35, and 40 Gy) and determined theactivity of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX). CAT andPOX activity significantly increased in B. dorsalis in the 1st larvae instar after high-intensity radiation doses(25–40 Gy) and played an important role in the antioxidant response to intensive radiation. The activity of POXin B. dorsalis at the 2nd larval instar sharply decreased after different doses of radiation, except for 10 and 40 Gy. Our results demonstrated that Co-60 radiation affected the activity of antioxidant enzymes and disturbed thephysiology of B. dorsalis, especially at early stages (the 1st, 2nd larvae instar). These three antioxidant defenseenzymes cooperatively play an important role in protecting B. dorsalis from oxidative damage.

书写范式的转型

The special geographical position of Korean Peninsula created the ancient Korean’s special culture linguistic context. The most obvious characteristic, was no more than the culture of Chinese characters spread and permeated in early days. Chinese writing took official writing, occupied the dominant position in Korea’s cultural history. Before <xun shi ping hua>to appear, Chinesecharacters wrote the pronunciation not according with the Korean. Also appeared several kinds in the folk to record the sound symbolic expression writing, until Xun min Zheng yin appeared, just really formed the national literature characters. The Chinesecharacter writing status had not still vacillated. Li Bian’s book carried on Chinese and taught the beginners mainly. Differently with <Lao qi da> and <Piao tong shi> ,this kind of written model as a result of conformed to Easten Confucianist’s writing to retain. This, to announcing that Korean cultural policy and the Confucianist writing model change, had the important help.

Cytomegalovirus Infection among Pregnant Women in Beijing: Seroepidemiological Survey and Intrauterine Transmissions

( Qing`e Jin ),( Jianrong Su ),( Shanna Wu ) 한국미생물 · 생명공학회 2017 Journal of microbiology and biotechnology Vol.27 No.5

Primary cytomegalovirus (CMV) infection during pregnancy can cause congenital defects. Available data for CMV infection during pregnancy in north China are inadequate. The aim of this study was to evaluate the epidemiology of maternal CMV infection and explore the incidence of congenital infection. In this prospective study, serum CMV IgG and IgM antibodies were measured in 2,887 pregnant women using ELISA, and the IgG avidity test was performed on all IgM-positive subjects. The seroprevalence of anti-CMV IgG was 94.70%, and of anti-CMV IgM was 1.28%. CMV IgG prevalence increased significantly with age (p < 0.01). Women living in downtown areas showed higher IgG prevalence than those residing in urban areas (p = 0.023). CMV-IgM seroprevalence was highest in autumn (p = 0.021). There was no difference in IgM seroprevalence by age, socioeconomic status, geographical area, or gravida. The rate of primary CMV infection was 0.45% (13/2,887) at the first trimester. The seroconversion rate during pregnancy was 0.76% (22/2,887). One woman underwent seroconversion during pregnancy and gave birth to an infant with asymptomatic CMV infection. Congenital CMV infection was diagnosed in five of the 14 infants from 14 mothers with active infection, for a vertical transmission rate of 35.71% (5/14). Three infants were asymptomatic, whereas two infants presented symptomatic infection with hearing deficits. Although CMV IgG prevalence is relatively high in north China, significant attention to primary CMV infection during pregnancy is still needed.

중국의 固體廢物汚染放置法

노청석,최동일 한국환경법학회 2004 環境法 硏究 Vol.26 No.3

This is a study on the Act on the Control of Solid Wastes of China. An outlines of this study is as follows : China is called as ‘factory of the world’ lately due to economy development which is caused by reform and opening policy, practical economy policy. In economy development process, China government is getting into trouble about the control of solid wastes. Developing Cities yield refuses of life, industrial wastes, dangerous wastes. Its disposal is connected directly with cities' survival. In order to solve this problem, Government have established 'Act on the Control of Solid Wastes' which is fundamental Act on solid wastes disposal in 1995, and 'Interim regulation on the Environment Protection Control of Waste Import', 'Regulation on the Control of Medical Waste', 'Measures on the Control of City's Radiation', 'Act on the Control of Radiation Pollution', 'Measures on the Control of Medical Instrument and Waste' and so on. These statutory laws adopted 'reclamation' as a main disposal means, but will adopt 'incineration' in future. And special provisions have been established for dangerous wastes and radiation wastes. Government will expand investment in this part. But most important policy is prior protection. We must make an effort to reduce a waste and recycle for sound and sustainable development.

中國에서의 環境犯罪

盧靑錫 한국환경법학회 2004 環境法 硏究 Vol.26 No.1

It's few and far between that many countries in the world are interested in environment. Actually the history of human being's development are exploiting the nature and the human being also got publishment from the nature because of such development, For example, global warming, desertification, weather unusual changing and so on. China is a huge country, so the environmental pollution problems are different and complicated according to the different area. There are many environment problems happened before and also many new problems are breaking out now. But the protection of environment and the lawmaking were late in China. The Chinese government didn't attach great important to the environment pollution in 1970', even they established the criminal law in 1979, the contacts of environment crime were very feeble. With the development of economy, the environmental problem were getting more serious, even many illegal acts happened. but there were no criminal regulations to control, instead they used the executive regulations. Later the environmental lawmaking developed and some criminal regulations were made. For example, ≪the environmental protection law≫, ≪Wild animals protection law≫, ≪the mining resources law≫ etc. But most of the criminal clauses are abstractly and actually the performance are very difficult after all. In the middle of 1980', some scholars proposed to strengthen the environmental criminal lawmaking, that was to add technical articles about environment crime to criminal law. After 1990, the Chinese government brought in the market economy system. In the cause of only pursuing the economical profits and ignoring the protection of environment, the environment pollution were getting more serious and also brought a heavy loss to the property. To provide against such a problem, the government called many experts to researched in the subject of environmental crime and many scholars of the judical world also published many thesis and books on such a subject. Finally, the government added the charge of "destruction of environmental resources protection", Even though there are only 9 clauses about the charge, the legal basis of publishing environmental crime are prepared in China. Even China have established technical clause about environmental crime in Criminal law, it is the first practise after all and also they haven't covered a wide range. So China should fill up the shortages of establishing environmental crime regulation continually.
