In this study, we described a suitable prioritisation scheme on these exempted drugs and established fundamental rules for residue monitoring enforcement in Korea. The principles of exempted materials were established. Based on these established criteria, 75 materials with high priority were selected and grouped. Among these materials, we have decided that 25 substances required further review for monitoring. Important factors for determining the priority for monitoring, product factor during the recent 4 years, veterinary medicine factors, including applied symptoms and component conditions, animal factors, including applied animals, and toxicological factors including acceptable daily intake (ADI), establishment of residual quantity permitted (MRL) or withdrawal periods, various provisory clauses and so on were set. High priority substances were acethylsalicylic acid, bromhexine, chlorpheniramine, and acetaminophen. In addition, we surveyed and provided analysis on the above mentioned materials in this study. The derived results will be suggested to the Animal and Plant Quarantine Agency (QIA) for development of guidelines of policy direction and the effective targeting for their monitoring program.

Purpose: Aims of this study were to investigate the agreement and test-retest repeatability of two methods for measuring magnitude of soft toric lens rotation. The two methods assessed were a newly developed mobile application for iPhone which uses the built-in camera function and the slit lamp biomicroscope. Methods: Agreement of ToriExpertä against known reference source was tested under experimental situation. For clinical measurement, thirty three participants (66 eyes) wore toric lens (prism ballast design) both eyes. Two investigators measured toric lens rotation using the two methods which are slit-lamp measurement(HS-700) and mobile application. First investigator used the same method twice for assessment of test-retest repeatability of each method. Inter- and intra-investigator agreement and repeatability were assessed using Bland-Altman analysis. Results: Against the known reference sources, mean variance was 0.52±0.75 degree and limits of agreement was ±1.47 degree (95% of Cls). The limits of agreement between the silt-lamp biomicroscope and mobile application methods was ±9.1 degree (95% CIs). Measurements using the two different methods showed no statistically significant mean difference (paired t-test, p=0.32). Inter-investigator agreement of lens rotation was ±7.9 degree (95% CIs) using the slit-lamp microscope and ±7.8 degree using mobile application. Intra-investigator repeatability was ±6.6 degree using the slit lamp microscope and ±6.8 using mobile application. Conclusions: The results should be considered in view of the fact that soft toric lenses are not static but move with the blink thus the location of the reference point is unlikely to be at exactly the same location at the different measurement times. Despite this source of variability in the results, the newly developed mobile application provides clinically comparable performance to slit lamp biomicroscope measurement which does not appear to be investigator dependent. This mobile application may provide sufficient precision to those optometric practices have limited access to slit-lamp biomicroscope for measuring soft toric lens rotation.

Porcine epidemic diarrhea virus (PEDV) causes acute diarrhea and dehydration in pigs with high mortality. PEDV is belong to Coronavirus, enveloped, single-stranded, positive-sense RNA virus. PEDV particles were composed of four structure proteins such as a glycosylated peplomer (spike, S) protein, envelope (E), glycosylated membrane (M) protein, and unglycosylated RNA-binding nucleocapsid (N) protein. Many of previous studies talk about this four structure proteins have a great potential to diagnosis and prevent PEDV. In this study we investigated expression of these structure proteins using the bacterial and baculovirus expression system. In bacterial expression system, our results showed that structure proteins fused polyhedrin and intein gene were expressed higher than non-fusion structure proteins. The expressed fusion proteins were used to immune mice for generating a polyclonal antibodies. In baculovirus expression system, co-infection of insect cells with these four recombinant baculoviruses led to self-assembly of virus-like particles as demonstrated by Transmission electron microscopy. They were confirmed by western blot analysis using pre-made polyclonal antibodies. Finding in this study may provide important information for vaccine and diagnostic development.

Insects are among the most diverse groups of animals on the planet, representing more than half of all known living organisms. These insects are found in nearly every environment. Although humans regard certain insects as pests and attempt to control them using insecticides, most insects perform complex ecological functions, and provide either direct or indirect economic benefits to humans. Recently, the importance of insects used as food sources or as pets has increased in many countries, including Korea. In addition, several insects have a strong influence on people's emotion. Insect-mediated mental healthcare program is designed to help people who have disorders with physical, behavior and development. Children who have mental disorder, the experimental group that was provided with an insect-mediated mental healthcare program over a total of 8 sections, one section per week, 60 minutes per section, followed by pre-test and post-test. They responded to therapeutic effect after the completion of the program. Further research on the basis of this study is expected to help children with emotional therapy in other areas.

The population of managed honey bees has been dramatically declining the recent past in worldwide. The one of most common disease of bees is nosemosis, the nosemosis is caused by microsporidia in the genus Nosema. Nosema apis and N. ceranae have been described as honeybee pathogens. These microsporidia are highly evoloved fungi with an obligately intracellular parasitic lifstyle. The disease causes significant detriment to honey production and results in economic losses. In our knowledge, Fumagillin is the only antibiotic approved for control of nosemosis in honey bees, however this antibiotic may have unintended effects on the honey bee host, ultimately contributing to increased prevalence and pathogenicity of Nosema. Therefore, we screened anti-Nosema substances from entomopathogenic fungal culture filtrates using in vitro polar tube germination assay. These fungal metabolites are employed as antibiotic agents. As results, Total 3 samples (23% of 13 total samples) showing the germinating inhibition against N. ceranae. This screening method may be useful for the detection of anti-Nosema substances from various samples and selected samples in this study may be a good feature to be used in the development of a new biocontrol method of nosemosis.

Anastatus orientalis Yang & Choi, 2015 (Hymenoptera: Eulpelmidae) is reported for the first time from Korea. It is a solitary endo-parasitoid in egg of Licorma delicatula (Hemiptera: Fulgoridae), Which causes damages to many ornamental and fruit trees in Korea. This species would be a good biological agent for suppression of the spotted lanternfly in Korea. More than 40 specimens of this species were collected in Cheonhyeon-dong, Hanam-city and Samsung-dong, Seoul city. This Korea species was compare with that from China in morphlogical characteristics and barcodes region of COI.

The genus Miaenia Pascoe, 1864 (Coleoptera Cerambycidae) in Korea is taxonomically reviewed in this study. Miaenia was erected by Pascoe (1864) based on the type species M. marmore. Miaenia has been accepted as a subgenus of Sciades for a long time, howerer, Roguet (2012) considered Sciades as a synonym of the genus Miaenia. Previously, two species, M. fasciata fasciata (Matsushita, 1943) and M. maritima Tsherepanov, 1979, of the genus have been reported in South Korea. In this paper, M. tonsa (Bates) is recorded in Korea for the first time. A key to the Korean Miaenia species, diagnoses, illustrations of diagnostic including male genitalia are provided.

A predatory genus Cryptalaus Ôhira, 1967 (Coleoptera: Elateridae) in Korea is taxonomically reviewed in this study. Up to date, two species of the genus Cryptalaus, C. berus Candèze, 1865 and C. larvatus pini Lewis, 1894, have been reported from Korea. From the present study, C. yamato Nakane, 1957 which has been regarded as an endemic to Japan, is reported from the Korean peninsula for the first time. A key to the Korean species of the genus Cryptalaus, diagnosis, illustrations of diagnostic characteristics are provided.

Cryopreservation of boar semen is continually researched in reproductive technologies and genetic resource banking in breed conservation. For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of spermatozoa indicates active metabolism, membrane integrity and fertilizing capacity. Various researches have been trying to improve the quality of semen post-thawed in boar. Recently, polymorphism (g.358A>T) of cluster-of-differentiation antigen 9 (CD9) gene reported to be significant association with MOT. Also, CD9 gene was expressed in the male germ line stem cells is crucial for sperm-egg fusion, and was therefore selected as candidate gene for boar semen. This study was conducted to evaluate the pig SNP (g.358A>T) of CD9 gene as a positional controlling for semen parameters of post-thawed boar semen. To results, the g.358A>T SNP of the CD9 gene was significantly associated with the traits such as MOT, curve linear velocity, straight line velocity, average path velocity and amplitude of lateral head displacement. Particularly, the g.358A>T SNP significantly has the highest association with MOT and animals with AA genotype (p<0.001). Therefore, we suggest that the g.358A>T in the intron 6 region of the porcine CD9 may be used as a molecular marker for Duroc boar Post-thawed semen quality, although its functional effect was not defined yet.

Pogonini Laporte, 1834 is one of the tribes in Trechinae Bonelli, 1810 (Coleoptera: Carabidae). This tribe is morphologically similar to Trechini, Benbidiini, Zolini and Patrobini of the subfamily. However, Pogonini can be distinguished from the other tribes by having a combination of the following characters: apical maxillary palpomere fusiform; umbilical series of setae on elytron more or less contiguous (though sparse in middle); each tarsomeres with a median sulcus on dorsal side. Pogonini includes about 85 species of 12 genera worldwide and is found in all zoogeographical regions of the world. Many species inhabit along the sea coasts or near salt lakes, and are recognized as halobiont. In Korea, Paik (1998) reported Pogonus (Pogonus) itoshimaensis Habu, 1954. However, he added only the species name in the checklist without description or illustration although few specimens were examined. After Paik’s study, any studies on taxonomic status and distribution of Korean Pogonini have not been carried out. The genus Pogonus Dejean is the largest group in Pogonini with two subgenera: P. (Pogonoidius Carret, 1903) and P. (Pogonus Dejean, 1821). These two subgenera share very similar external morphological characters; Pogonoidius has setae on anterior angles of pronotum and setae at 7th interval of elytra while Pogonus does not have them. In the present study, two species, Pogonus (Pogonus) japonicus Putzeys, 1875 and P. (Pogonoidius) punctulatus Dejean, 1828, are newly recognized from Korea. A key to the Korean Pogonini species, redescription, distribution, photos of diagnostic characters, and illustrations of male and female genitalia are provided.

The aim of this study was to carry out the comparative analysis of the brushing force following various brushing techniques bytoothbrush mounted pressure sensing unit. The study group consisted of 10 dental hygienist participants. The brushing forces (on buccal area of each first molar) were monitored on 8 different kinds of brushing techniques; Fones, Bass, Rolling, Scrub, Charters, stillman, Modified bass and Modified stillman. In Bass, Charters, Fones and Scrub method, force distributions showed a small gap of maximum and minimum value (Max/Min) while a big difference was noted in Modified bass, Modified stillman, Rolling and Stillman methods. Especially, the biggest difference of Max/Min value was observed in the area of lower left first molar. In conclusion, highly delicate manual skill is needed in showing big error range of force distribution. It means that careful force needs to be focused during toothbrushing instruction when a delicate manual skill was carried out.

4-isopropyl-2,6-bis(1-phenylethyl)aniline 1 (KTH13-AD1) is a metabolite of Cordyceps bassiana that has been traditionally used to treat various inflammatory disease. Even though it has the magnificent pharmaceutical potential, there was not much understanding on its anti-inflammatory actions. Therefore, this study was aimed to determine the anti-inflammatory effects of KTH13-AD1. We found that KTH13-AD1 suppressed nitric oxide (NO) and reactive oxygen species (ROS) production in lipopolysaccharide (LPS)- or sodium nitroprusside (SNP)-treated macrophages (RAW264.7 cells). Similarly, mRNA expression of inducible NO synthase (iNOS) and tumor necrosis factor-a (TNF-a) analyzed by RT-PCR and real-time PCR was also reduced by this compound. Interestingly, KTH13-AD1 also strongly diminished the levels of NF-kB-mediated luciferase activities and nuclear translocated NF-kB family proteins. In agreement with these, KTH13-AD1 suppressed the upstream signaling pathway for NF-kB activation including IkBa, IKKa/b, AKT, p85/PI3K and Src in time- and dose-dependent manners. Therefore, these results strongly suggest that KTH13-AD1 has a strong anti-inflammatory activity via suppression of the NF-kB signaling pathway.

Multi-walled carbon nanotube reinforced epoxy composites were fabricated using shear mixing and sonication. The mechanical, viscoelastic, thermal, and electrical properties of the fabricated specimens were measured and evaluated. From the images and the results of the measurements of tensile strengths, the specimens having 0.6 wt% nanotube content showed better dispersion and higher strength than those of the other specimens. The Young's moduli of the specimens increased as the nanotube filler content was increased in the matrix. As the concentrations of nanotubes filler were increased in the composite specimens, their storage and loss moduli also tended to increase. The specimen having a nanotube filler content of 0.6 wt% showed higher thermal conductivity than that of the other specimens. On the other hand, in the measurement of thermal expansion, specimens having 0.4 and 0.6 wt% filler contents showed a lower value than that of the other specimens. The electrical conductivities also increased with increasing content of nanotube filler. Based on the measured and evaluated properties of the composites, it is believed that the simple and efficient fabrication process used in this study was sufficient to obtain improved properties in the specimens.

Propolis is a health food, known that high antioxidant and antimicrobial effects, fresh cut vegetables that rapidly increasing consumption has recently faced the problem storability fall down after washing. To improve storability of fresh cut vegetables are being carried out various studies. In this study, using the characteristics of propolis we were performed to improve the storability of fresh cut vegetables. There was prepared in 20% solution of propolis extracts, by using this solution, propolis solution prepared diluting 0.001 to 1%, were dipped in fresh vegetables (cabbage lettuce, sesame leaf, and lettuce). Vegetables were measured the sensory evaluation and hardness after each treatment by placing in a certain period of time at room temperature and refrigerator. When cabbage lettuce was stored for 3 days at refrigerater, sensory evaluation that the cleavage site is not generated browning in 0.1% propolis solution showed the best results, the hardness was the most excellent. During refrigerated storage after treatment in a 0.01% solution of propolis sesame leaves showed good sensory evaluation include freshness, morphological change of leaves, and high hardness. After treatment propolis of 1% solution at room temperature, Sesame leaves showed the most heavily defensive fragility phenomenon after three days. It was found that the appearance of the side effect, when the concentration of the propolis is rather high. If lettuce is chilled to handle after propolis treatment, after 10 days in the solution from 0.01 to 0.1% showed excellent sensory evaluation, and high hardness. These results confirmed that the storage stability is excellent compared to non-treated as if diluted to 0.1-0.01% propolis solution is to improve the shelf life of fresh vegetables using.

Porcine parvovirus (PPV), a member of the genus Parvovirus, family Parvoviridae, is a significant causative agent in porcine reproductive failure, causing serious economic losses in the swine industry. PPV is a non-enveloped virus and its capsid is assembled from three viral proteins (VP1, VP2, and VP3). The major capsid protein, VP2 is the main target for neutralizing antibodies in PPV. When VP2 was expressed in large amounts, it assembled into virus-like particles (VLPs) similar in size and morphology to the original virions. In this study, we generated the recombinant Bombyx mori nucleopolyhedrovirus (BmNPV) to express the VP2 protein. Expression of the VP2 protein was analyzed by SDS-PAGE and Western blot. The recombinant VP2 protein of approximately 64 kDa was detected by both analyses. The formation of VLP by recombinant VP2 was confirmed through transmission electron microscopy examination. The purified VP2 protein assembled into spherical particles with diameters ranging from 20 to 22 nm.
