The objectives of this study was to evaluate the degradability and digestibility of crude protein (CP), rumen undegradable protein (RUP), and individual amino acids (AA) on six by-product feedstuffs (BPF) (rice bran, RB; wheat bran, WB; corn gluten feed, CGF; tofu residue, TR; spent mushroom substrate from Pleurotus ostreatus, SMSP; brewers grain, BG) as ruminants feed. Three Hanwoo steers (40 months old, 520 ± 20.20 kg of body weight) fitted with a permanent rumen cannula and T-shaped duodenal cannula were used to examine of the BPF using in situ nylon bag and mobile bag technique. The bran CGF (19.2%) and food-processing residue BG (19.7%) had the highest CP contents than other feeds. The RUP value of bran RB (39.7%) and food-processing residues SMSP (81.1%) were higher than other feeds. The intestinal digestion of CP was higher in bran RB (44.2%) and food-processing residues BG (40.5%) than other feeds. In addition, intestinal digestion of Met was higher in bran RB (55.7%) and food-processing residues BG (44.0%) than other feeds. Overall, these results suggest that RB and BG might be useful as main raw ingredients in feed for ruminants. Our results can be used as baseline data for ruminant ration formulation.

The aim of the study was to investigate the effects of incentive spirometry and Ujjayi breathing technique on the pulmonary function of smokers. Subjects were individuals who had a smoking habit of at least a year. Subjects were randomly divided into 3 groups: the incentive spirometry group (n=8), Ujjayi breathing technique (n=9), and a group applying both incentive spirometry as well as Ujjayi breathing technique (n=8). Each intervention was performed twice a day, 5 times a week, for a total of 8 weeks whereupon the change in pulmonary function was evaluated. A spirometer was used to measure FVC, FEV1, and FEV1/FVC. The survey used for this study included the Fagerström Test of Nicotine Dependence (FTND) and the Shortness of Breath Questionnaire (SOBQ). Study results for the comparison within groups showed that in the group that performed both the incentive spirometry and Ujjayi breathing technique, FEV1 improved with statistical significance (p<.05). Furthermore, within this comparison the FEV1/FVC improved with statistical significance. Comparison amongst the groups showed no statistically significant differences in all areas. Following, to effectively increase pulmonary function in young adult smokers, both incentive spirometry and Ujjayi breathing technique should be employed together.

Pilomatricoma is the second most common benign dermal-subcutaneous tumor of the head and neck region, after epidermoid cyst, originating from the outer sheath cells of the hair follicle. It can be easily treated with surgical excision. However, it is a relatively unknown skin lesion to maxillofacial surgeons. Therefore, we report a case of pilomatricoma occuring inferolateral area of the parotid gland in a 54-year-old man; with a review of the relevant literature.

In this study, we investigated the effects of different pre-treatment conditions such as blanching and drying process to improve its quality. Bracken samples were treated by drying (70°C for 40 min), blanching (100°C for 2 min) or mixed (blanched and dried [BD]), respectively. These treated samples were analyzed for their physicochemical properties such as pH, color and microbial growth. The pH of bracken increased from 6.6 to above 6.9 through all treatment. From color observation, the L* and b* values increased after drying process, whereas, the a* values decreased. Water contents of bracken decreased by about 80% from 93% through drying process. After samples treated by pre-treatments, hardness increased, especially after drying process. For the microbial study, raw bracken had 5.6 log CFU/g of aerobic bacteria and 2.8 log CFU/g of total coliform. Blanched and BD samples had about 2 log CFU/g of aerobic bacteria and 1.8 log CFU/g of total coliform, acceptable for food. From our results, it is concluded that the properties of blanched samples had similar to raw samples to guarantee for microbial safety. From the obtained results, the blanching process without drying process is necessary to apply freezing process as pretreatments.

Even though plant protections using chemical pesticides have several advantages, non-specific toxicities to other beneficial insects and humans and rapid development of tolerance and/or resistance of target pests to chemicals are major disadvantages. Recent researches suggested that using double stranded RNA (dsRNA) could be species specific and environmental friendly pest management protocols. However, efficiency of dsRNA treatments are known to be variable according to its application methods. For example, injections of dsRNAs to pests were known to be effective in all species. However, efficiencies of oral application of dsRNAs were known to be dependent on species. Thus, development of tools that could enhance the efficacy of orally treated dsRNAs are utmost important for widening usages of dsRNAs in plant protection. Recently, we found that the efficacy of oral treated dsRNAs to target pests could be enhanced by nano-technologies. I will show how applying nano-technology to dsRNAs enhance the efficiency of dsRNAs. (This work was carried out with the support of the Cooperative Research Program for Agriculture Science & Technology Development (Project title: Studies for biological characteristics of and control methods against the migratory locust, Locusta migratoria, Project No: PJ011630042016), Rural Development Administration).

Mucormycosis generally presents as an acute infection manifesting in rhinocerebral, pulmonary, gastrointestinal, cutaneous, or disseminated forms. Fungal invasion to the arteries can reduce blood supply by thrombi formation inside the blood vessels, leading to necrosis. Fungal infection usually initiates in the upper turbinate, paranasal sinus, or less commonly in the palate or pharynx. Here we report an unusual case of mucormycosis in the maxilla of a 75-year-old man and present a review of the literature.

In this study, we propose an efficient two-phase heuristic policy, called an acceptance tolerance control policy, for Infrastructure as a Service (IaaS) cloud services that considers both the service provider and customer in terms of profit and satisfaction, respectively. Each time an IaaS cloud service is requested, this policy determines whether the service is accepted or rejected by calculating the potential for realizing the two performance objectives. Moreover, it uses acceptance tolerance to identify the possibility for error with the chosen decision while compensating for both future fluctuations in customer demand and error possibilities based on past decisions. We conducted a numerical experiment to verify the performance of the proposed policy using several actual IaaS cloud service specifications and comparing it with other heuristics.

Cambodia covers an area of 181,035 sq km, among them, forests cover 53 percent, so there are abundant Insect diversities. Collecting expeditions of Insect were conducted from towns of Osam (first base camp, N 12° 04' 51.7" E 103° 12' 30.5" alt. : 549m) and Roveang (second base camp N 12° 19' 06.5" E 103° 3' 03.8" alt. : 53m) in Pursat Province, western part of Cambodia. As protected forest from government, these areas were almost natural conservation field. Pitfall trap, sweeping method, light trap and searching etc. were used to collect insect. Specially in this expedition, large or big sized beetles, more than 5cm body length, for example, Lucanidae, Cerambycidae, Elateridae etc., mostly collected from light trap in deep forest. Materials are expected more than 100 species belonging to 20 families but it was difficult to identification because of lack of references of this areas. Maybe lots of new or new recorded species will found from Cambodia. Among Coleoptera species, with big sized beetles as the central figure, photos for species of dominant, rare, nominated species of new or new recorded were introduced, and also collecting sites and activities were presented.

The Black Soldier Fly (BSF, Hermetia illucens) was widely distributed throughout Korea. This insect was mainly found in the vicinity of and in cattle sheds, manure sheds, living waste dump grounds, and food waste dump grounds. This fly is a kind of a beneficial fly because BSF adults do not go into houses, they do not regurgitate on human food, they do not bite, bother or pester humans in any way and they are not associated in any way with the transmission of disease. But their greatest attribute lies their ability to eat and digest raw waste. They can devour, for example, a large, raw, Irish potato and others in just a few hours. Unlike many other flies, since the BSF larvae have very powerful mouth parts and digestive enzymes, they can ingest raw waste far more efficiently than any other known species of fly. On this study, to investigate whether feeding strategy of the BSF larvae involves extra-oral digestion or not, and to better understand this process, the salivary glands and a few tissue from the BSF were dissected and subjected to morphological and preliminary enzyme characterization.

Varroa destructor is an ecto-parasite mite and worldwide pest of the honey bee Apis mellifera L. The pyrethroid tau-fluvalinate (Apistan), an acaricide that is tolerated by honey bees, has been used for varroa mite control since the mid 1980s. Even though various resistances to tau-fluvalinate in varroa mites have been reported from Europe, Israel, and USA, the nature of tau-fluvalinate resistance in varroa mites in Korea has never been investigated. To investigate and understand tau-fluvalinate resistance in varroa mites in Korea, we conducted bioassay in several apiaries located different regions in Korea. To understand the molecular mechanisms underlying the difference of tau-fluvalinate resistances in varroa mites, partial genomic DNA fragments of a voltage-sensitive sodium channel gene from varroa mites were cloned and sequenced, since tau-fluvalinate is known to act on the sodium channels directly. Two novel mutations in sodium channels of varroa mites were present in eight apiaries. Two mutations might be a geographical polymorphism of sodium channel of varroa mites in Korea.

Bumblebees are important pollinators in greenhouse and have colonized all parts of the World. In Korea, the value of bumblebees is increasing as pollinator. However, the more recent use of reared colonies may ultimately allow pathogens to spread to peripheral areas for bumblebees. Generally, bumblebees are hosts to a large number of parasites which are mites, flies, protozoa, fungi, virus and bacteria. For most of these, very little is known about their effects against host insect, epidemiology or evolutionary ecology. So, we report pathogenic bacteria isolated from Bombus terrestris and B. ignitus at first time in Korea. Bacillus fusiformis and Klebsiella oxytoca are isolated from B. terrestris and confirmed with 16S rRNA gene nucleotide comparison in NCBI genebank. Pathogenicity of B. fusiformis was 35~40% against B. terrestris. Pantoea dispersa and K. oxytoca are isolated from B. ignitus and confirmed with 16S rRNA gene nucleotide comparison in NCBI genebank. Pathogenicity of these species were 35~40% against B. ignitus. These pathogenicity are considered as low-level.

μ방lt emitting diodes (LED) devices are commercially introduced as an alternative for low-Ievellaser therapy (11ι，T) ， and it has several advantages over lasers such as a safe, efficient, and less-expensive altemative to treat wounds. And LED irradiation at the same biostimulatory wavelength has similar bíochemical effεαs. In the present study, to asses whether the I핑ht-emitting diode (LED) irradíation can stimulate bone regeneration, irradiated bony defects with or without grafting materials on rat calvaria were compared to corresponding nonirradiated control. Fifty male Sprague-Dawly rats weighing about 150g, were used. Factors for present study were designed as follows, 1) presence or absence of grafting materials, 2) with or without irradiation, and 3) number of irradiation. Two weeks after operation, rats were sacrifìced. Radiologic and 비stomorphologic fmdings were evaluated. Macrospically, there were no incidents of infection, dehiscence, hematoma and necrosis during study. Radiological findings showed greater radiopacity in the graft group and radiopacity increased as the number of irradiation increase. And microscopically, new bαle formation was great in the graft group and increased as the number of irradiation increase, Present study has shown that LED irradiation improved bone regeneration through radiologic and histomorphologic fmdings in rat.

Background : Undulatum Rhubarb, commonly produced in domestic, is rhizome of Rheum undulatum L. that belongs to the family Polygonaceae. It also can be used as a substitute of R. palmatum L., R. tanguticum Maximowicz ex Balf., and R. officinale Baillon which completely depend on import system. However, there should be clear clarification among Undulatum Rhubarb and Rhubarb, because Undulatum Rhubarb contains rhaponticin as marker compound that is not indicated at Rhubarb. Some of the recently imported Undulatum Rhubarbs have been found to be Rhubarb. Also, it is known that only Undulatum Rhubarb is cultivated at domestic environment. But some plant origins of Rhubarb are grown in Korea, too. Further study are needed to clarify clear origin between Undulatum Rhubarb and Rhubarb. Thus, we collected some domestically cultivated samples and identified them. Methods and Reseults : Rheum undulatum L., Rhubarb, Rheum tanguticum Maximowicz ex Balf. which were cultivated in Gangwondo Agricultural Research and Extension Services in Cheorwon were collected and anayzed the DNA sequences. We also compared DNA sequences in Rhubarb collected from England and R. rhabarbarum L., R. undulatum L., and R. franzenbachii on NCBI. As a result, two kinds of rhubarb cultivated in the test plantation were identified as R. rhabarbarum and R. officinale. In addition, R. undulatum (plant origin of Undulatum Rhubarb) was identified as Rhubarb (Rheum rhabarbarum) in England with 99 - 100% identical in nuclear ITS gene region. Conclusion : R. undulatum, plant origin of Undulatum Rhubarb, is reported as synonym of R. rhabarbarum, R. franzenbachii. Rheum speices which are cultivated as tester in Gangwondo Agricultural Research and Extension Services in Cheorwon are estimated as R. undulatum and R. officinale. Therefore, not only Undulatum Rhubarb but Rhubarb could be grown in Korea.
