Biological control has been tried for integrated pest management. It is often comparable, safe, and environment-friendly, making itself an alternative for chemical agents. Filamentous microorganisms, i.e., fungi and streptomystes, produce many kinds of useful metabolites, and some of them have been developed as a biocontrol agent. However, they still have a long way because of the concern of manufacturing cost. Therefore, process development was intensively studied to meet cost-effectiveness. Operating conditions of bioreactor, e.g., agitation and aeration, had an effect on biological and physiological responses such as mycelial morphology, oxygen and nutrient transfer. Understanding relationship between operating parameters and microbial responses in terms of growth, substrate and oxygen consumption, and production yield was critical for process development. This study dedicated to build strategies for mass production of biological control agent using aerobic filamentous microorganisms.

Chemical communication is very important for survival and reproduction in insects. The successful survival of insects depends to a large extent on the ability to detect and recognize environmental signals. We can manage the insect pest populations by eco-friendly methods by understanding the chemical communication systems which lie among the host trees, pests, and natural enemies. Persimmon is the largest fruit tree in acreage in Korea. Many insect pests are attacking various part of persimmon. Major insect pests of persimmon in Korea are Riptortus pedestris, Halyomorpha halys, Plautia stali as hemipterans, Stathmopoda masinissa, Euzophera batangensis, Conogethes punctiferalis as lepidopterans, There are also some minor insect pests including Homona magnanima, Apolygus spinolae, Synanthedon tenuis, bark beetles et cetera. Some of these produce sex pheromones to attract conspecific females or produce aggregation pheromones to gather conspecific individuals. Interestingly, some insect pests are using the semiochemicals of other species, pheromones or floral scents, as kairomones to find hosts or oviposition sites. These relationships in chemical communications at persimmon ecosystem will be discussed using our research results and others so far.

Insect antennae play important roles in finding mates and in locating food source and oviposition sites. Riptortus pedestris is an important pest of soybean and sweet persimmon in Korea. The male R. pedestris adult produce the aggregation pheromone attracting the conspecific nymphs and both sexes of adults. The pheromone was known as a cue for food finding, but the 1st instar nymph can develop to the 2nd instar without food. This phenomenon may suggest that the 1st instar nymph may have different sensilla system from other instars. Thus, we investigated the morphology and distribution of antennal sensilla and antennal response to the aggregation pheromone (AG) of each nymphal stage using Scanning Electron Microscope (SEM) and Electroantennography (EAG). As expected, first instar nymph did not have sensilla trichodea 3 (T3) and chaetica 3 (Ch3) which existed in other instar nymphs. The antennae of the 1st instar nymph did not responded to AG, with no difference from control. For further elucidation of the functions of sensilla T3 and CH3, single sensillum recording to AG will be done.

The purpose of this systematic review is to investigate the effects of tape application on improving body conditions. The search strategy for this review included a literature search by members of the International Kinematic Academy in 12 countries between January 2014 and February 2015 using PubMed, CINAHL, Cochrane, Google Scholar, websites and national journals. The search words included“Kinesiotape, Kinesio tape, kinesiotaping, elastic taping, taping, functional taping, myofascial taping, sensomotor taping”. The review included all articles, even those published in different languages. These searches resulted in 821 publications. There are several effects of tape application were revealed such as improving blood circulation, lymphatic circulation, body range of motion, activation of mechanoreceptor and joint stability, and decreasing pain. No one negative about the positive effects of taping, however the more effort is required to find evidence of effects of tape application.

The purpose of this study is to explore the effects of mobilization of C0-C1 and C7-T1 applied to asymptomatic individuals with reduced upper cervical rotation during the FRT. Design: parallel randomized controlled trial. 48 subjects(38.52 years±15.13) with C1-C2 rotation hypomobility in TFR joined the study and were randomized into three groups(C0, C7, control group). FRT in both directions was measured before and after the intervention. C0 intervention consisted of a dorsal translatoric mobilization of C0-C1 in the cervical neutral position. C7 intervention consisted of a ventral cranial translatoric mobilization of C7- T1 in neutral position and the control group maintained a supine position. C0 group experienced a FRT ROM to the restricted side increase of 17.64。(SD=4.55), that was significantly greater (P<0.001) than 5.95。 (SD=4.81) of the C7 group and 2.45。(SD=5.05) of the control group. The results showed that a dorsal translatoric mobilization of C0-C1 in neutral position restored the physiological FRT mobility in subjects with C1-C2 hypomobility and experienced statistical significant improvement in FRT as compared to a C7-T1 translatoric mobilization and a control group. (Level of evidence: 1b).

This study presents a potential environmental design, rather than the application of the environmental design technique model, to enhance the biodiversity of desolate space. Utilizing the main theories of landscape ecology in relation to vegetation and habitat restoration models, can allow for environmental restoration and the creation of climate change adaptation models to develop existing areas with specific topographical conditions, and allow for the utilization of the ecological base as a terrain recovery plan derived from the application of environmentally friendly design. We believe that the implications of this study will allow for the future creation of urban public parks and restoration of the ecological environmentally friendly design by using applied modeling techniques. Finally, we believe the suggestions outlined here provide a pilot case that delineates the value of the shared space as well appropriately address climate change.

Arsenic is an environmental pollutant and is known to induce toxicity. Arsenic acts on cells through a variety of mechanisms, influencing numerous signal transduction pathways. It induces a variety of cellular effects such as apoptosis, growth inhibition, promotion or inhibition of differentiation and angiogenesis. Arsenic has been associated with cancers of the skin, bladder, lung, kidney, and liver as well as with noncancerous conditions, diabetes and hepatopathy. However, arsenic trioxide (ATO) was reported to induce remission in patients with acute promyelocytic leukemia (APL). The anticancer efficiency of ATO was not restricted to APL; however, it has been extended to many solid tumors, including liver, cervical, prostate, lung, esophagus, and bladder tumors. Therefore, in this study, a number of previous studies are summarized that demonstrate arsenic-induced toxicity, including carcinogenesis and anticancer activity in vitro and in vivo. The arsenic metabolism that is involved in arsenic-induced toxicity is also discussed.

The work presented in this report was a detailed comparative study of the electrochemical response exhibited by graphite anodes in Li-ion batteries having different physical features. A comprehensive morphological and physical characterization was carried out for these graphite samples via X-ray diffraction and scanning electron microscopy. Later, the electrochemical performance was analyzed using galvanostatic charge/discharge testing and the galvanostatic intermittent titration technique for these graphite samples as negative electrode materials in battery operation. The results demonstrated that a material having a higher crystalline order exhibits enhanced electrochemical properties when evaluated in terms of rate-capability performance. All these materials were investigated at high C-rates ranging from 0.1C up to 10C. Such improved response was attributed to the crystalline morphology providing short layers, which facilitate rapid Li+ ions diffusivity and electron transport during the course of battery operation. The values obtained for the electrical conductivity of these graphite anodes support this possible explanation.

This paper addresses the effect of dopants on the electronic properties of zigzag (8, 0) semiconducting single walled carbon nanotubes (SWCNTs), using extended Hückel theory combined with nonequilibrium Green’s function formalism. Through appropriate dopant concentrations, the electronic properties of SWCNTs can be modified. Within this context, we present our ongoing investigation on (8, 0) SWCNTs doped with nitrogen. Quantum confinement effects on the electronic properties of the SWCNTs have also been investigated. The obtained results reveal that the electronic properties of SWCNTs are strongly dependent on the dopant concentration and modification of electronic structures by hydrogen confinement.

Mesenchymal stem cells (MSCs) are multipotent stem cells, which can be induced to differentiate into several cells. MSCs are also reported to possess immunomodulatory properties through secretion of inflammatory cytokines and generation of regulatory T (Treg) cells. Treg cells play an important role in allergic disorders, including atopic dermatitis. We examined the immunomodulatory effects of canine adipose tissue derived-MSCs (cAD-MSCs) in 3 groups: Group 1, untreated normal dog; Group 2, dogs with Dermatophagoides farinae ointment-induced atopic dermatitis; and Group 3, dogs with atopic dermatitis. Canine peripheral blood mononuclear cells (PBMCs) were collected from each group and co-cultured with cAD-MSCs. After co-culturing, PBMCs were separated and the expression of Treg cells was examined by flow cytometry. According to the results, the populations of Treg cells were increased in 3 ex vivo experimental groups, co-cultured with cAD-MSCs. These results would be important for the application of MSCs in clinical trials.

Garlic (Allium sativum) is known to have antimicrobial effects but there are few data on its effects against fish pathogenic bacteria. This study was conducted for possible development of natural food antimicrobials from garlic extracts, particularly allicin. The filter sterilized, aqueous extract of garlic was tested for its ability to inhibit the growth of 7 fish pathogenic bacteria (E. tarda, V. ichthyoenteri, V. harveyi, P. damselae, S. iniae, S. parauberis, L. garviae) using the disc diffusion test, minimum inhibitory concentration test, and minimum bacteriocidal concentration test. The garlic extract inhibited growth and killed most of the organisms tested. The disc diffusion test was performed using garlic extracts (100%, 50%, 25%, 10%, each 20㎍), and MIC test was also performed using a diluted concentration of garlic extracts (488 - 250,000 ㎍/㎖). According to the results, garlic extracts exhibited antimicrobial activity against all of seven bacteria, and these results suggest that this garlic extract can be used as an antimicrobial substance against fish bacterial diseases in the fish industry.

Rainfall infiltration velocity into the surface of the earth is influenced by time sequential change of the urban surface spatial structure following urban expansion, and is the key factor in determining runoff discharge. In this regard, a comprehensive assessment and understanding of surface runoff associated with land cover change, as well as the changed structure of the landscape, is required to establish landscape planning. Sustainable development, planning and maintenance of the green space inside the city, based on results of the above, are a fundamental countermeasure for relieving fragmentation of the urban green space and increasing urban flood damage, directly or indirectly. In this study, we conducted analysis of landscape structure and change of Surface Runoff Reduction Capacity (SRRC) using the land cover maps from 1975 to 2000 at the lower reaches of the Jungrang stream (LRJS). The results are expected to provide baseline data for sustainable landscape planning that is ecologically healthy and can improve SRRC during torrential rains. The results of this study are as follows. Analysis of the results showed that land cover type underwent a remarkable change in terms of the total area of farm and urban types from 1975 to 2000. The total area of farm decreased by approximately 27.05% during the 25 years, while that of urban increased by approximately 25.61%. In this regard, the results of the landscape structure assessment using FRAGSTATS showed reciprocal tendencies, which intensified fragmentation of the landscape, as measured by all 6 of the selected factors, including LPI, NP, PD, LSI, AI and PLADJ. The Runoff Curve Number (CN) value steadily increased in the results of the time series landscape change assessment of the SRRC from 1975 to 2000. Based on analysis of the changed area associated with SRRC classes, the high SRRC class 1 area showed a steady decrease in accordance with the progression of the time series land use change associated with urban development.

Lignocellulosic biomass conversion to biofuels such as ethanol and other value-added bio-products including activated carbons has attracted much attention. The development of an efficient, cost-effective, and eco-friendly pretreatment process is a major challenge in lignocellulosic biomass to biofuel conversion. Although several modern pretreatment technologies have been introduced, few promising technologies have been reported. Microwave irradiation or microwave-assisted methods (physical and chemical) for pretreatment (disintegration) of biomass have been gaining popularity over the last few years owing to their high heating efficiency, lower energy requirements, and easy operation. Acid and alkali pretreatments assisted by microwave heating meanwhile have been widely used for different types of lignocellulosic biomass conversion. Additional advantages of microwave-based pretreatments include faster treatment time, selective processing, instantaneous control, and acceleration of the reaction rate. The present review provides insights into the current research and advantages of using microwave-assisted pretreatment technologies for the conversion of lignocellulosic biomass to fermentable sugars in the process of cellulosic ethanol production.

스티픈 밀러의 『일요일의 특이한 이력』은 대서양 양안의 영어 사용 저술가 들의 일요일에 관한 다양한 생각을 살피는 책이다. 그들 중에는 목사, 화가, 소 설가, 시인, 철학자, 비평가 등이 포함된다. 밀러는 기독교인들을 대강 세 그룹 즉 준수자들, 실천하지 않는 자들, 타락한 자들로 나누었다. 준수자들에게 일요 일은 성일이며, 또 다른 이들에게 일요일은 성일이자 휴일이다. 일요일을 성일 로 아는 사람들은 보통 엄격한 일요일 준수로 몰아가는 안식일 준수자라 불린 다. 안식일 준수 가정에서 자란 작가들은 대개 우울한 일요일을 지냈으며 그들 은 어린 시절의 경험에 대하여 부정적으로 반응하였다. 일요일에 관한 논쟁들은 종교개혁 이후 역사를 통하여 성과 속 두 축 사이에서 우왕좌왕하는 흐름을 이 루어 온 것으로 보인다. 현재 철저한 안식일 준수 강조의 힘이 약하지만, 곧 강 한 힘으로 돌아올 수 있을 것이다. 밀러의 책은 많은 자료를 섭렵하였다. 매우 흥미롭고 지식이 풍부한 책이지만 가끔 산만한 것이 흠이다.

We developed a polymerase chain reaction (PCR)-based molecular method for sexing and identification using sexual dimorphism between the Zinc Finger-X and -Y (ZFX-ZFY) gene and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for mitochondrial DNA (mtDNA) cytochrome B (CYTB) gene in meat pieces and commercial sausages from animals of different origins. Sexual dimorphism based on the presence or absence of SINE-like sequence between ZFX and ZFY genes showed distinguishable band patterns between male and female DNA samples and were easily detected by PCR analyses. Male DNA had two PCR products appearing as distinct two bands (ZFX and ZFY), and female DNA had a single band (ZFX). Molecular identification was carried out using PCR-RFLP of CYTB gene, and showed clear species classification results. The results yielded identical information on the sexes and the species of the meat samples collected from providers without any records. The analyses for DNA isolated from commercial sausage showed that pig was the major source but several sausages originated from chicken and Atlantic cod. Applying this PCR-based molecular method was useful and yielded clear sex information and identified the species of various tissue samples originating from livestock.

This study was carried out to determine the basic mycelial culture conditions for Poria cocos growth. According to colony diameter and mycelial density, suitable media for mycelial growth were Malt yeast extract, Potato dextrose agar, Yeast extract agar, and Yeast malt agar. The optimum temperature for mycelial growth was between 25 and 35oC, and the optimum pH value was between 4 and 7. Carbon and nitrogen sources were fructose and yeast extract. The optimum C/N ratio was about 10 to 1 with 2% glucose. Other minor components for optimal growth were thiamine-HCl and nicotinamide as vitamins, acetic and lactic acid as organic acids, and MgSO4·7H2O and FeSO4·7H2O as mineral salts.

This study was conducted to determine the effects of supplementary lighting intensity and duration on selected Cassulaceae species grown in a hydroponic system. Five subfamilies in Crassulaceae with corresponding species were chosen as experimental units namely Sedeveria ‘Letizia ’, Sedum ‘Sun Red’, Crassula rupestris, Echeveria ‘Momotaro’, and Graptoveria opalina. Light duration (3 and 6 hours) and intensity (4,000 lux or 60 μmol • m−2 • s−1 and 8,000 lux or 120 μmol • m−2 • s−1), and their combinations served as factors which were replicated twice. Results revealed that the use of supplementary lighting using LED fixtures had influenced selected species under Crassulaceae. The use of three hours supplementary lighting under low light intensity had statistically similar results with those of the control S. letizia, C. rupestris and G. opalina in particular parameters. Meanwhile, succulents under six-hour with high intensity condition grew well, compared to species S. letizia, C. rupestris and E. ‘Momotaro,’ demonstrating that the data was significantly different. Interestingly, there were no statistical significant differences between species C. rupestris and the control regardless of change of variables (duration and intensity) in all parameters.

A commercial NiO (green nickel oxide, 86 wt% Ni) powder was reduced using a batch-type fluidized-bed reactor in a temperature range of 500 to 600 oC and in a residence time range of 5 to 90 min. The reduction rate increased with increases in temperature; however, agglomeration and sintering (sticking) of Ni particles noticeably took place at high temperatures above 600 oC. An increasing tendency toward sticking was also observed at long residence times. In order to reduce the oxygen content in the powder to a level below 1 % without any sticking problems, which can lead to defluidization, proper temperature and residence time for a stable fluidized-bed operation should be established. In this study, these values were found to be 550 oC and 60 min, respectively. Another important condition is the specific gas consumption rate, i.e. the volume amount (Nm3) of hydrogen gas used to reduce 1 ton of Green NiO ore. The optimum gas consumption rate was found to be 5,000 Nm3/ton-NiO for the complete reduction. The Avrami model was applied to this study; experimental data are most closely fitted with an exponent (m) of 0.6 ± 0.01 and with an overall rate constant (k) in the range of 0.35~0.45, depending on the temperature.

The Korea Microlensing Telescope Network (KMTNet) is a wide-eld photometric system installed by the Korea Astronomy and Space Science Institute (KASI). Here, we present the overall technical specications of the KMTNet observation system, test observation results, data transfer and image processing procedure, and nally, the KMTNet science programs. The system consists of three 1.6 m wide-eld optical telescopes equipped with mosaic CCD cameras of 18k by 18k pixels. Each telescope provides a 2.0 by 2.0 square degree eld of view. We have nished installing all three telescopes and cameras sequentially at the Cerro-Tololo Inter-American Observatory (CTIO) in Chile, the South African Astronomical Observatory (SAAO) in South Africa, and the Siding Spring Observatory (SSO) in Australia. This network of telescopes, which is spread over three dierent continents at a similar latitude of about 􀀀30 degrees, enables 24-hour continuous monitoring of targets observable in the Southern Hemisphere. The test observations showed good image quality that meets the seeing requirement of less than 1.0 arcsec in I-band. All of the observation data are transferred to the KMTNet data center at KASI via the international network communication and are processed with the KMTNet data pipeline. The primary scientic goal of the KMTNet is to discover numerous extrasolar planets toward the Galactic bulge by using the gravitational microlensing technique, especially earth-mass planets in the habitable zone. During the non-bulge season, the system is used for wide-eld photometric survey science on supernovae, asteroids, and external galaxies.

Background: Prone hip extension (PHE) can be performed to measure the lumbopelvic motor patterns and motions. Imbalances in lumbopelvic muscle activity and muscle weakness can result in instability including pain in lumbopelvic region. The posterior oblique sling (POS) muscles contribute to dynamic lumbopelvic stability. In addition, POS are anatomically aligned with the trapezius muscle group according to shoulder positions. Objects: This study compared the electromyography (EMG) activity of POS and pelvic compensations during PHE with and without pre-activation of lower trapezius muscle (lowT). Methods: Sixteen healthy males were recruited. PHE was performed in randomized order: PHE with and without lowT pre-activation. Surface EMG signals were recorded for biceps femoris (BF), gluteus maximus (GM) (ipsilateral), lumbar multifidus (MF) (bilateral), and the lowT (contralateral). An electromagnetic tracking motion analysis was used to measure the angle of pelvic rotation and anterior tilting. Results: The ipsilateral GM and bilateral MF EMG amplitudes were greater during PHE with lowT pre-activation compared to PHE without lowT pre-activation (p<.05). The BF amplitude during PHE without lowT pre-activation was significantly greater than that during PHE with lowT pre-activation (p<.05). The angles of pelvic rotation and anterior tilting during PHE with lowT pre-activation were significantly smaller compared to PHE without lowT pre-activation (p<.05). Conclusion: PHE with lowT pre-activation, which is aligned with the POS, showed more increased MF and GM muscular activity with smaller lumbopelvic compensations in rotation and anterior tilting compared to PHE without lowT pre-activation.
