A flight suit worn by fighter pilots in the Korea Air Force is in the form of coveralls and can be donned/doffed with a slide fastener located on the center front of the body. This all-in-one styled garment encompasses the easy movement of an Air Force pilot in the cockpit (Choi, 2012) as well as protects from flames in an emergency. The standard Korean flight suit was designed based on a modulated American flight suit (Jeon, Park, You, & Kim, 2010); however, it is necessary to develop a new Korean flight suit with a Korean pilot-centered design. This study investigates wearing conditions and satisfaction of Korean flight suit wearers and provides basic data for a user-centered Korean flight suit design. Researchers visited two Korea Air Force wings and interviewed the fighter pilots. The results of the interview were derived through a questionnaire. The main topics of the questionnaire were: demographics, actual wearing conditions, size/fit, subjective perceptions of comfort on mobility, satisfaction of appearance, frequency of pocket usage, improvement requirements and fabric satisfaction. A total 439 questionnaires were collected in January 2015 and 428 used for analysis analyzed (except for 11 female responders).The average age of respondents was 29.12±4.67 years old and their mean work experience was 5.96±4.46 years. Over half of those questioned were captains(52.6%).The results of the questionnaires are summarized as follows. First, only 45.8% of respondents filled their chest size; however, most of them completed their height and weight. There were 52.8% who referred to their height (or used eye measurement)when selecting the flight suit size, even though the actual sizing system for Korean flight suits suggests a height and chest size by choice. It is necessary to offer new guidelines in which the wearer could select their size easier. Second, the summer flight suit appearance satisfaction was significantly lower(p<0.01) than winter flight suits and could infer (based on the pre-interview responses) that the air- summer suit vents might be a factor that lowered the appearance satisfaction. Third, the responders felt crotch and shoulder inconvenience during body motions; therefore, it is important to set quantitative standard of ease based upon the extension of skin surface and anthropometric properties of pilots. Forth, questions on suit fabric indicated that they were generally satisfied with protection characteristics such as anti-electrostatic qualities (3.27±0.78, 5-point Likert scale) while comfort characteristics such as thermal insulation, absorbency and elasticity indicated a relatively low satisfaction (2.39±0.794, 2.99±0.87 and 2.65±0.83 respectively, 5-point Likert scale). Therefore, fabric development is also needed to improve user satisfaction. Fifth, survey respondents had a negative opinion on changing flight sites. They preferred improvements in quality or better ease of length and width. Therefore, we have to find a way to improve flight suit function with respect to current designs rather than pursuing a dramatic change of appearance.

Measuring body size with a 3D scanner can reduce inter-measurer variability and provide better accuracy compared to using a traditional methods of measurement (Park, Nam, & Park, 2009). Many size measurement projects (or studies) that measure body size established a size measurement method prior to the development of a 3D scanner and automatic size measurement programs that produce 3D virtual body size measurements (Park, &Nam, 2012). Size data measured through an automatic size measurement program are more accurate and have a lower variability that is more appropriate for body measurements (Han, & Nam, 2004; Nam, Choi, Jung, & Yun, 2004). However, this method is limited to healthy subjects who can maintain a correct posture in a 3D scanner. It is difficult for the elderly to maintain the correct posture for body measurements in ‘Basic Human Body Measurements for Technological Design’ of ISO 7250(1997). Body measurement definitions are based on vertical and horizontal directions consequently, it is hard to measure those with a bent body type even if they stand in a correct posture. Most body measurement items are automatically measured in vertical and horizontal directions because current automatic size measurement programs utilize algorithms based on typical body measurement definitions. The size measurement method based on a vertical and horizontal directions tends to have a problem for elderly individuals with a bent body type who have difficulty maintaining a correct posture for 3D scanning as defined in ISO 7250(1997)(Ashdown, & Na, 2008).This study analyzes the problem of present auto-measurement programs that use elderly’s 3D body scan data. We conducted a comparative analysis of elderly’s body sizes using an auto-measurement program from virtual 3D body scan data and direct measurement with traditional measurement methods. We establish 34 typical body size measurements for the use of data from 464 males and 472 females (total 936) between the ages of 70 to 85. For error analysis, data separated to normal values and outliers compared with ISO 20655(2003). ISO 20685 defines the accuracy of extracted measurements by classification and measurement type (segment lengths, body height/breaths/depth, large/small circumferences, and head/hand/foot dimensions). The majority of outliers for the male and female body height type was “height”. Total number of persons with outliers for Height’s data was 603; consequently, 64.4% of subjects (elderly group of 70-85 yrs.) could not maintain a correct posture when scanning. Other data also had many errors from inaccurate measurement postures. A total of 72.3% of males and 70% of females have incorrect values in small circumferences. The segment lengths’ error data was 76.5% of males and 75% of females; in addition, the head dimension’ outliers were 87% for both male and female subjects. Especially 57.46% of males had incorrect data, while 74.67% of females had a type of large circumference. Female chest circumference had significant errors due to sagging breasts. The differences identify with a correlation between type of large circumference (chest, hip, under bust, waist, waist of omphalion) and gender. There were several correlations between the many measurement errors because values over 70% of data have outliers; however, each measurement type has properties in regards to correlation. A substantial positive correlation was found between all measurements (except hip circumference) in the type of large circumference; in addition, one-way ANOVA indicated that the measurements influenced height and were statistically significant. Outliers found in height data for the elderly’s were more likely to have errors in the type of large circumference. The type of body height indicated a strong correlation and statistical significance between the axilla height and other measurements (height, waist, crotch, lateral malleolus). Axilla height with more outliers indicated that other type of body height measurements had a higher potential for errors. The posture for body measurement was standardized as standing erect; however, this study indicated that many measurement errors were possible between using an auto-measurement program and direct measurement. The value of outlier about a particular measurement item can expect increased errors about any group (height: large circumference group/ axilla height: body height group). We have to study the relation in measurements in these types ‘large circumference’ because ‘head dimensions’ types correlate between measurements in each group. We need a more detailed analysis about outliers to find the major factors for measurement errors in regards to the elderly as well as discuss the possibility of ISO measurement-standard’s application for the elderly.

The purpose of this study was to find out an inspiratory muscles training program’s therapeutic effects on stroke patients’respiratory function. For the purpose, this study targeted 20 stroke patients being hospitalized in K hospital in Daegu, and diveded the patients into the both groups of Inspiratory muscle training(IMT) group and control group, randomization. The 10 patients in the IMT group was applied the inspiratory muscles training. The control group was composed of other 10 patients. IMT group was given a inspiratory muscle training program for 30 minutes per times, 5 times a week for 6 weeks. The investigator measured the patients’respiratory function compared changes in the function and ability before and after the IMT. The results of this study are as follows. Investigating the inspiratory muscle training group’s lung functions, there appeared some significant differences in the tests the FVC(Forced vital capacity), FEV1(Forced expired volume in one second) before and after the training(p<.05), but the control group had no significant in the same tests before and after(p<.05). The differences in the both groups after depending the inspiratory muscles training were significantly found in the tests of FVC, FEV1, FEV1/FVC(p<.05). The maximum inspiratory pressure showed some significant differences in the inspiratory muscle training group(p<.05), but didn't show any significant difference in the control group(p>.05). Conclusionally, it will be judged that the inspiratory muscles training program will improve stroke patients’respiratory function, and it is considered that will move up stroke patients’gait and body function.

The effect of increased carbon dioxide concentration in atmosphere was examined on the pheromone system of Helicoverpa armigera reared from egg stage to adult in three room. Two of three room (2×2×2 m) were treated with carbon dioxide gas as 600 ppm and 1,000 ppm, respectively. Mean of carbon dioxide concentration was 429.1 ppm in the control, 603.3 ppm for 600 ppm, and 1011.5 ppm for 1,000 ppm during experiment. Electroantenograph (EAG) test was conducted on 3-d-old male adults with air, hexane, and a series of their sex pheromone component, Z11-16Al, from 0.01 to 100 ng. The result was that male EAG responses of 600 and 1,000 ppm were 30.3% lower than that of control room. Production of Z11-16:Al was examined on about twenty 2-d-old virgin females. Carbon dioxide increases did not show a statistically significant difference. However, higher amount of sex pheromone was produced in females of 600 and 1,000 ppm. So, This experiment was replicated with different population reared again. The amount of the sex pheromone per female was 108.9 and 118.1 ng in control room, 139.8 and 141.8 ng in 600 ppm room, and 124.6 and 125.8 ng in 1,000 ppm room.

Antibiotic Detection Kit (Combination I), a lateral flow immunoassay (LFIA) developed for the detection of antibiotic residues in milk, was utilized for the analysis of antibiotic residues in the muscle tissue of olive flounder. After 60-min treatment by dipping in water dosed with ampicillin (200-g/ton water), the residue depletion of ampicillin was investigated in 25 cultured olive flounder (Paralichthys olivaceus). Muscles of fish were sampled on the 1st, 2nd, 3rd, 4th and 5th day after drug treatment. The concentration of ampicillin in the muscle was determined by LFIA. The absorbance ratio of the sample to the control blank (Bs/Bo) was employed as an index to determine the muscle residues in olive flounder. To investigate the recovery rate, standard solutions were added to muscle samples to give final concentrations in the muscle of 4 and 8 ng/ml. The recovery rates of all spiked samples were > 96% of the spiked value. Ampicillin was detected in the muscle of fish treated with the drug until the 2nd day of the withdrawal period. The present study showed that the LFIA can be easily adopted to predict ampicillin residues in tissue of farmed fishes.

토마토 TYLCV는 병이 발생되면 약제나 다른 방법으로 방제가 어려우므로 내병성 품종의 개발이 반드시 필요하다. 특히, TYLCV 저항성 유전자 Ty-1,2,3(부분우성)을 한 개체 내로 집적을 시켜서 저항성이 증대된 품종의 개발이 필요하다. 토마토 TYLCV 저항성 11-TY1-AV 등 7계통을 대상으로 보독인 담배가루이를 이용하여 표현형을 조사하였다. 이병성 대비(11-TY5-AV; 슈퍼썬로드)와 F3 세대 3계통 및 F2 세대 4계통을 TYLCTHV 균주를 이용하여 접종하였다. 접종 13일 후에 이병성 대비가 100% 이병증상을 나타내었으며, 이때 11-TY4-AV는 48개체 중에서 23개체가 이병되었으며, 11-TY6-AV는 42개체 중에서 14개체, 11-TY7-AV는 48개체 중에서 14개체, 11-TY8-AV는 48개체 중에서 15개체가 이병 되었다. F2 세대 4 집단 모두 p>0.05 수준에서 TYLCV 접종 후 표현형이 정상적인 유전분리비(3:1)를 보이는 것을 확인 하였다. 또, TYLCV에 저항성인 동일한 자원을 부계로 사용하더라도 모계로 어떤 것을 사용 하느냐에 따라서 저항성 정도가 다르게 나타나는 것을 확인할 수 있었다.

In mammal, oocytes are arrested at the metaphase Ⅱ until fertilization. However, unfertilized oocytes that remain in the oviduct or under in vitro culture, which is called "oocyte aging". Asynchrony negatively affects fertilization, pre- and post-implantation embryo development. Caffeine is known to phosphodiesterase inhibitor that rescues oocyte aging in several species. Nevertheless, the effect of caffeine was not clear in bovine aging oocytes. In this study investigated the cytoskeleton distribution in aged oocytes and the embryo development ability of aged oocytes from treated with or without caffeine during maturation. The cumulus and oocyte complexes (COCs) were cultured in 10% FBSTCM199 for up to 22h at 38.5℃ in 5% CO₂. For oocyte aging study, the COCs were cultured in 10% FBS-TCM199 supplemented with or without 10 mM caffeine for 40hs. And then oocytes underwent in vitro fertilization using highly motile sperm recovered from frozen and than thawed bull semen. As a result normal cytoskeleton percentage of caffeine treatment group more than the aging group (67.57%±4.11 VS 44.61%±6.40) and no significantly different compared to control group. Aged oocytes derived from addition of caffeine to the in vitro maturation medium significantly increased the percentage of 2- cell that developed to the blastocyst stage compared to the aging group. Blastocysts derived from caffeine treatment group significantly increased the total cell number compare aging (90.44%±10.18 VS 67.88%±7.72). Apoptotic fragmenting of genomic DNA was measured in individual embryos using the TUNEL assay. Blastocyst derived from caffeine treatment group significantly decereased the apoptotic index compared to blastocyst derived from aging group. In conclusion, we inferred that the caffeine treatment during oocytes aging periode can improved the develpmental rate and quaility in bovine embryos developing in vitro.

Two species entomopathogenic fungi most widely used and valued in traditional Asian medical practice are Ophiocordyceps sinensis (formely Cordyceps sinensis) and Cordyceps militaris. Although O. sinensis may be the more famous and expensive fungus, it is also comparatively rare and cannot be grown or made to fruit readily in culture whereas C. militaris occurs worldwide, can be easily cultured, and is the easist of all Cordyceps species to fruit in culture. There is a well establihed cottage industry in Korea to produce C. militaris as a dietary supplement or even as a culinary ingredient used to promote improved health. Most of the Korean farmers raising C. militaris obtain fruiting bodies from silkworms that are injected with suspensions of hyphal bodies grown in liquid cultures. This study seeks to facilitate and to simplify the injection process used to produced this fungus by finding a simple cullture medium on which abundant supplies of the Lecanicillium conodial state of C. militaris are produced and can be used with simplified injection protocols involving spraying or dipping in conidial suspensions than the more material- and labor- intensive injection protocol. The studies to be repored include quantitative tests of conodial yields on varying carbon sources, varying nitrogen sources, and attempted to optimize the carbon/nitrogen ratio and pH of the medium for conidial production.

Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces tenuipes Jocheon-1. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. Paecilomyces tenuipes Jocheon-1 cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes Jocheon-1 was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDHis comprised of 1,014bp encoding 338 amino acid residues. The deduced protein sequence of Pt-GAPDH showed higher homology with Beauberia bassiana-GAPDH(93% amino acid identity). Hydropathy analysis revealed that Pt-GAPDH protein is hydrophilic. The major three amino acids in its composition of amino acid residues were alanine(11.54%), valine(9.47%) and glycine(8.88%). The cDNA encoding Pt-GAPDH was expressed as a 37 kDa polypeptide in baculovirus-infected insect Sf9 cells. The Pt-GAPDH gene of Paecilomyces tenuipes entomopathogenic fungus consisted of three exons and two introns coding for 338 amino acid residues, and the genomic DNA length of the gene spans 1302bp. The accession number of the gene in GenBank are GU997099 for Pt-GAPDH cDNA and GU997102 for Pt-GAPDH genomic DNA.

This study investigated whether the simple view of reading framework is supported among Upper elementary Korean EFL learners. Specifically, the relative contributive power of two emergent literacy factors, word decoding and linguistic comprehension abilities, which have been identified as the main determinants of successful reading comprehension, was examined. Ninety nine fifth grade students in Korean elementary school participated in this research, and their decoding skills, listening comprehension abilities, and reading comprehension in English were measured. The findings revealed that both English decoding skills and linguistic comprehension ability were significant predictors of their English reading comprehension, which supports the simple view of reading within the Korean EFL context. Specifically, decoding skill explained more of the variance, compared to linguistic comprehension, in reading comprehension when controlling for each other. The result is discussed in terms of the overall development of L2 proficiency and the role of L2 exposure in L2 reading comprehension development.

Fungi belonging to the Paecilomyces spp. have recently been used as food and herbal medicines in Korea and are greatly popular as commercially available powdered supplement or dried fruiting body. Despite this acceptance and its use, little is known of the genes related to its reactive agents. Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces spp. based on the previous identification of ITS1 and ITS2 at the molecular level and collected from Jocheon Miryang, Korea. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes- Jocheon was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDH is comprised of 1,014bp encoding 338 amino acid residues. The deduced protein sequence of Pt-GAPDH showed higher homology with Beauberia bassiana-GAPDH(93% amino acid identity). Hydropathy analysis revealed that Pt-GAPDH protein is hydrophilic. The major three amino acids in its composition of amino acid residues were alanine(11.54%), valine(9.47%) and glycine(8.88%). The Pt-GAPDH gene of Paecilomyces tenuipes entomopathogenic fungus consisted of three exons and two introns coding for 338 amino acid residues, and the genomic DNA length of the gene spans 1302bp. The accession number of the gene in GenBank are GU997099 for Pt-GAPDH cDNA and GU997102 for Pt-GAPDH genomic DNA. More investigation works including gene expression, immunological analysis etc. will be carried continuously without hesitation after this presentation.

Previously, we found that expression by translational fusion of the polyhedrin (Polh)-green fluorescence protein (GFP) led to the formation of granular structures and these fluorescent granules were easily precipitated by high-speed centrifugation. Here, we developed an easy, fast, and mass purification system using this baculovirus expression system (BES). An enhanced GFP (EGFP) fused with Polh gene at the N-terminus including an adaptor and enterokinase (EK) site between Polh and EGFP was expressed in Sf9 cells. The cells infected by AcPolhEKA-EGFP produced fluorescent granules. The EGFP fusion protein was purified from granule-containing cells according to three steps; cell harvest, sonication and EK digestion. Through the final enterokinase digestion, EGFP was presented mainly in the supernatant (93.3%) and the supernatant also showed a pure EGFP band. These results suggest that the combined procedure of Polh fusion expression and enterokinase digestion can used for the rapid and easy purification of other proteins.

To identify DNA markers linked to a elytra polymorphism, amplified fragment length polymorphism (AFLP) analysis was performed on DNA samples from four each colour pattern individuals (2 females and males), for example, succinea 1, succinea 2, conspicua, and spectabilis. As a result of performing AFLP analysis with the restriction endonuclease combination EcoRⅠ and Mse I, total of 2,269 AFLP fragments which were specific to succinea, conspicua and spectabilis was identified using 24 different AFLP primer combinations. Among these 2,269 fragments, 16 bands which were the most specific to one color patterns were isolated, cloned and sequenced. Subsequent UPGMA cluster analysis revealed that population of H. axyridis was divided four major group and these genetic tree showed that H. axyridis elytra colour diversity was affected by genetic polymorphism. It is considered that these genetic analyses may be facilitated the understanding of molecular genetic mechanism related with the wing colour pattern formation in this species.

This research was conducted to determine the effect of condensed tannin (CT) on the quality of fermentation and nutritive value of "Demark" alfalfa. During the ensiling, the production of NH₃-N and NDF decreased while the concentration of lactic acid in increased apparently as the CT was added.

The Maillard Reaction Products (MRPs) such as Glucose-tyrosine (Glu-Tyr) and Xylose-arginine (Xyl-Arg) have antioxidant, antimutagenic, and antibacterial effects. However, to date, still little is known about the other biological effects of the MRPs. In this study, we investigated whether the fructose-tyrosine MRP, 2,4-bis(p-hydroxyphenyl)-2-butenal (Fru-Tyr), could modulate cell cycle progression and NF-κB activity, and thereby induce apoptotic cell death of colon cancer cells. Treatment with different concentrations (10-40 μg/ ml) of Fru-Tyr for 24 h inhibited colon cancer cell (SW620 and HCT116) growth followed by induction of G₂/M phase cell cycle arrest and apoptosis in a dose-dependent manner. We also found that Fru-Tyr suppressed tumor necrosis factor-alpha (TNF-α)-induced NF-κB transcriptional activity. Moreover, Fru-Tyr induced the expression of apoptotic gene, cleaved caspse-3. These results suggest that Fru-Tyr inhibited colon cancer cell growth through induction of G₂/M phase cell cycle arrest and apoptotic cell death by modulating of NF-κB.

A full genomic DNA microarray technique was employed to investigate the effects of Dongchunghacho on aortal and hepatic gene expression in apolipoprotein E knockout mice fed a high-fat/high-cholesterol diet. Male 8- week - old ApoE-/- mice were randomly divided into two groups, control(high cholesterol group; HC) and supplementation of Dongchunghacho (SD). All of the mice were fed a high-fet/high cholesterol diet with or without Dongchunghacho supplemented by 1% for 6 weeks. At first, lipid profile of the Dongchunghacho was measured by biochemical analysis. No differences were observed in serum triglyceride and total cholesterol levels between the two groups. Antigenotoxic effect of the Dongchunghacho was measured by the single cell gel electrophoresis assay (Comet assay) and quantified as % fluorescence in tail. Dongchunghacho supplementation decreased significantly leukocytic DNA damage and also there was a tendency of reduction in hepatic DNA damage in Dongchunghacho group compared with the control group. In up regulated genes in liver and aorta of the mice, genes with 0 to 2- fold difference in expression level between the two group (HD and SD) was very much more in liver than in aorta, on the contrary, those with 2-fold to 16-flod difference increased greatly rather in aorta than in liver. Also, almost the same results were observed in down regulated genes in liver and aorta between the two groups. These results suggested that supplementation of Dongchunghacho might be helpful in preventing leukocytic DNA damage induced by high fat diet, and has a more crucial roles in aortal gene expression.

(E,E)-8,10-dodecadienyl acetate (E8E10-12:Ac) and (E)-8-dodecaenyl acetate (E8-12:Ac) have been selected as the candidate chemicals for sex pheromone components of the M. phaseoli, female through GC-EAD tests, whereas the two compounds and an additional candidate, (E,Z)-7,9-dodecadienyl acetate (E7Z9-12:Ac), have been found at a ratio of 7:1:1 in the abdominal tip extract (Yum et al., 2008). In order to determine the actual composition of sex pheromone, therefore, several blends using the three chemicals were evaluated for attractiveness to males of M. phaseoli around red bean and soybean fields. Individual components as well as two blends consisted of E8E10-12:Ac/E7Z9-12:Ac and E8-12:Ac/E7Z9-12:Ac did not show attractiveness, whereas the blend of E8E10-12:Ac/E8-12:Ac showed an increased effect in male capture. Of the tested blends with all three chemicals, the 7:1:2 composition of E8E10-12:Ac, E8-12:Ac and E7Z9-12:Ac attracted the most number of males. The results suggested that E7Z9-12:Ac is one of the sex pheromone components and may act as a synergist.

As indigenous aphid parasitoid, Aphelinus varipes kill aphids for feeding in addition to parasitization. Because of this characteristic of A. varipes, this parasitoid may have the possibility of biological control agent against aphids. So we have evaluated traits such as daily paratization, total parasization, number of aphids killed by host feeding, sex ratio, development time, pupal mortality of A. varipes parasitizing green peach aphid, Myzus persicae. At 25°C and 16L:8D, longevity, total paratization and host feeding of A. varipes female was 11.0, 25.3, and 63.3 days, respectively. And development time of male and female, sex ratio (M:F), pupa mortality of offspring of A. varipes were 12.0 days, 12.5 days, 0.88, and 11.6%, respectively. However, because these results are not enough to estimate potential of A. varipes as biological control agents/factors, other factors such as host suitability (Macrosiphum euphorbiae, Aulacorthum solani), effect of temperature, and host seeking behavior of A. varipes continually will be investigated.
