This study aims to examine how the body and clothing of Jesus Christ are represented in the Russian Transfiguration of Christ icons of the 15th and 16th centuries and why it is considered to have established a distinct Russian iconography free from Byzantine influence. The study analyzes the Russian icons comparing them with their Byzantine prototypes to identify the distinctive ‘Russianness’ of the representation. The research methods comprise a qualitative analysis of the literature on Russian Orthodoxy, Russian icons, Christian theology, and Christ’s clothing and an empirical analysis of the icons. The scope of the study is limited to Russian icons from the 15th and 16th centuries and Byzantine icons from the 9th century onwards. The study found that, compared to Byzantine icons, the Russian icons exhibit a more elongated body, darker facial features, and lighter clothing. A statistical analysis using the Mann-Whitney U test further revealed that the Russian icons feature a stiffer, simpler form, more opaque material, and more defined clothing boundaries. These stylistic differences suggest that the ‘Russianness’ in the expression of Christ’s body and clothing in the Transfiguration of Christ icons derives from creativity, abstractness, and tradition. Rather than a simple recreation of the historical Christ or adherence to the Byzantine tradition, the Russian iconographic representation emphasizes Christ's transfiguration into a luminous form, as described in the Bible, accentuating his divine nature over his human aspects.

파리목(Diptera) 집파리과(Muscidae)에 속하는 토마토어리줄기집파리(Atherigona orientalis)는 열대·아열대 지역에서 분포하며 고추, 토마토 등 기주 특이성이 없어 여러 식물에 흔히 발견되는 해충이다. 현재까지 우리나라 작물에 피해는 보고되지 않았으나 국외 사례로 볼 때 우리나라 작물에서도 큰 피해를 유발할 것으로 예상되어 식물방역법상 관리해충으로 지정하여 관리하였다. 2016년 경상북도 의 성군에서 첫 국내 분포가 보고되었다. 우리는 이 종의 지역별 분포 현황 등을 확인하기 위하여, 2017년 4월부터 10월까지 전국 각지에 트랩을 설치하여 분포 조사를 실시하였다. 조사결과 총 2,601개체가 전국적으로 조사되어 국내에 널리 분포하고 있음이 확인되었다.

Excessive body weight gain during the growth period of early life may predispose individuals towards obesity and metabolic disorder in later life. We investigated the possibility of using the food efficiency ratio as an early indicator for predicting susceptibility to diet-induced obesity and insulin resistance. Four-week-old, prepubertal, male Sprague Dawley rats were divided into obesity-prone and obesity-resistant groups based on food efficiency ratio values after five days on a high-fat diet. Metabolic parameters measured after 2, 6, and 10 weeks, and specific phenotypes were compared with each group. Obesityprone rats had higher increases in body weight and fat mass compared to obesity-resistant rats over the study period. Obesity-prone rats became glucose intolerant early in this study and remained so throughout the experimental period, with increases in fat weight and leptin levels occurring first, followed by increases in insulin level. Gluconeogenesis and insulin resistance significantly increased in obesity-prone groups in which activities of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase were increased and glucokinase activity decreased. Higher food efficiency ratio at an early age was closely correlated with body fat accumulation, hyperleptinemia, and hyperinsulinemia of middle and elderly age. We suggest a high food efficiency ratio in prepubertal subjects may be a useful predictor of future obesity and insulin resistance.

The purpose of this study was to investigate the effects of combined wedge on the range of motion in ankle and knee joint, ankle eversion moment and knee adduction moment, and center of pressure excursion of foot for genu varus among adult men during gait. This study was carried out with 10 adult men for genu varus in a motion analysis laboratory in J university. The subjects of the experiment were measured above 5cm width between the knees on contact of both medial malleolus of ankle while standing. The width of their knees in neutral position was measured without the inversion or eversion of the subtalar joint by the investigator. The subjects of the experiment were ten who were conducted randomly for standard insole, insole with 10° lateral on rear foot wedge, insole at 10°lateral on rear foot and 5° medial on fore foot wedge. Before and after intervention, changes on the range of motion in ankle and knee joint, ankle eversion moment and knee adduction moment, and center of pressure excursion were measured. In order to compare analyses among groups; repeated one-way ANOVA and Scheffé post hoc test were used. As a result, combined wedge group was significantly decreased compared to control wedge group in terms of knee varus angle in mid-stance(p<.05). Combined wedge group was significantly decreased compared to lateral wedge group in terms of ankle eversion moment in whole stance(p<.05). Combined wedge group was significantly decreased compared to lateral wedge group in terms of knee adduction moment in whole stance(p<.05). Combined wedge group was significantly decreased compared to lateral wedge in terms of center of pressure excursion in whole stance(p<.05). The results of this study suggest that combined wedge for genu varus decreased ankle eversion moment and knee adduction moment upon center of pressure excursion. We hypothesize that combined wedge may also be effective in the protection excessive ankle pronation.

본 연구는 홀스타인 거세육우(총 18두, 생후 4개월령, 체중 160kg)의 성장단계별 농산부산물 TMR 사 료의 에너지 수준(T1, TDN 75~84%; T2, TDN 77~85%)과 출하월령(18, 20 및 22개월)별로 배치하여 각 출하월령별 등심과 우둔육의 육질 및 관능특성을 조사하였다. 등심육의 경우 근내지방함량은 처리구 1은 22개월령 그룹이, 처리구 2는 20개월 및 22개월령 그룹이 유의적으로 가장 높았다(P<0.05). 우둔 육의 경우 처리구 1과 2가 모두 22개월령 그룹이 근내지방 함량이 가장 높았다(P<0.05). 처리구 2는 18개월령 그룹이 단백질 및 수분함량이 유의적으로 가장 높았다(P<0.05). 콜라겐 함량은 처리구 모두 출하월령간에 유의적인 차이가 없었다(P>0.05). 육질특성에서 등심육은 처리구 1의 경우 보수력, 전단 력, 가열감량, 육색에 있어서 급여기간 그룹간 유의적인 차이가 없었다(P>0.05). 처리구 2에서는 보수 력만 18개월과 20개월령 그룹이 가장 높았다(P>0.05). 우둔육은 처리구 1의 경우 보수력, 전단력, 가열 감량, 육색의 백색도에 있어서 급여기간 그룹간 유의적인 차이가 없었으며 단지 육색에서 적색도와 황 색도만 22개월령이 가장 높았다(P>0.05). 처리구 2의 경우 18개월령 그룹이 보수력이 가장 높았고 전 단력은 가장 낮았으며 가열감량은 18개월과 20개월령 그룹이 낮았다(P<0.05). 관능특성에 있어서 등심 육의 경우 처리구 1은 18개월과 20개월령이 연도점수가 높았고 20개월령 처리구가 향미 및 전반적인 기호도 점수가 유의적으로 높았다(P<0.05). 처리구 2는 연도, 다즙성, 향미 및 전반적인 기호도 점수 모두 20개월과 22개월령이 유의적으로 높았다(P<0.05). 우둔육의 경우 처리구 1은 연도가 18개월과 20 개월령이 유의적으로 높았고 전반적인 기호도는 20개월령이 유의적으로 높았다. 처리구 2는 18개월령 이 연도만 유의적으로 높았다(P<0.05). 결론적으로 홀스타인 거세육우는 농산부산물 TMR 사료를 22개 월령까지 급여한 그룹이 근내지방도는 높았으나 육질 및 관능특성은 18개월령 또는 20개월령이 더 우 수하였으므로 이러한 점을 고려하여 출하하는 것이 바람직할 것으로 생각된다.

The objective of this study was to determine the effects of E. coli on boar sperm quality and reproductive performance in sows after artificial insemination. Three different levels of E. coli were artificially inoculated to semen with following concentrations; Control, 500, 5,000 and 50,000 colony forming unit (cfu)/ml. Semen samples were preserved at 17℃ for 5 days. Sperm motility was significantly decreased (p<0.05) on day 3 in the group inoculated with 5,000cfu/ml compared to control groups. In all treatment groups, sperm motility was gradually decreased as storage time increased, but the decline pattern was more drastic in the groups inoculated with 5,000 and 50,000 cfu/ml groups from day 3 (p<0.05) compared to control group. After 3 day of storage at 17℃, sperm viability in sample inoculated with the highest concentration (50,000 cfu/ml) of bacteria was less (p<0.05) than that of control group. The pH of semen sample pH was maintained 7.2～7.5 in all groups during the experimental period. No differences (p>0.05) were found for both storage time and bacterial concentration. The pregnancy rate and live born piglets tend to decrease by increasing the concentration of E. coli in semen. In particular, the rate of pregnancy was lower in the group inoculated with 50,000 cfu/ml (58.3%) compare to the other groups (81.8, 75.0, 76.5%). These results suggest that the contamination of E. coli in boar semen negatively affects fertilizing ability of boar sperm and the reproductive performance obtained from sows after artificial insemination.

This study was conducted to investigate the effects of the slaughtering age on carcass characteristics and economic efficiency of Holstein steers. The Holstein steers (n=27, 4 months old, average body weight 160 ㎏) were divided into 3 groups and raised with TMR feeding formulation until 18, 20 and 22 months old, respectively. In the result, final body weights were 703, 768 and 804 ㎏, and average daily gains were 1.32, 1.32 and 1.27 ㎏, respectively. Dry matter intakes (DMI) were 8.62, 8.94 and 9.24 ㎏. Feed conversion ratio was 6.53, 6.77 and 7.28 for 18, 20 and 22 months old groups. Feed conversion ratio was increased as the fattening periods increased. In yield traits, carcass weight was significantly lower in 18 months old group compared to other groups (p<0.05). The back fat thickness were 8.4, 7.3 and 7.8 ㎜, rib eye area were 70.6, 73.4 and 73.84 ㎠, and the meat yield index was 62.9, 62.5 and 62.1 when slaughtered at 18, 20 and 22 months old, respectively. In the frequency of the yield grade (A:B:C, %), grade B was highest at 20 months old group as 0:75:25. In the quality traits, marbling score, texture and maturity were not different among slaughtering age groups. However, marbling score tended to be increased at 22 months old group. Meat color and fat color were higher at 22 months old group compare to other groups (p<0.05). In the frequency of the quality grade (1+:1:2:3,%), 22 months-old group was the greatest as 12:0:50:38. The income was highest for 20 months old group as 279 thousand wons among the 3 groups. Therefore, the slaughtering ages of Holstein steers may be appropriate at 20 months old.

A total of 30 Korean native pigs (gilt 15, boar 15) were used to investigate the carcass characteristics, meat quality, amino acid, and fatty acid composition by gender. The carcass weight of boars were significantly higher than gilts, whereas the carcass yield of gilts had significantly higher than boars (p<0.01). Boars had significantly higher moisture contents in loin muscle than gilts, whereas the protein contents of loin muscle had significantly higher in gilts than boars (p<0.01). In the results of meat quality analysis, the cooking loss (p<0.01), shearing force (p<0.05), lightness (L) and yellowness (b) in meat color (p<0.05) were significantly higher, but the pH was significantly lower (p<0.01) in gilts compared with boars. Arginine (p<0.05), alanine, aspartic acid, histidine, leucine, lysine, phenylalanine, serine, threonine and tyrosin (p<0.01) for gilts were significantly higher than those for boars. The results of fatty acid composition showed that gilts had significantly higher contents of C16:1n7, C18:1n9, C20:1n9 (p<0.01) than boars in intramuscular fat, whereas boars had significantly higher contents of C18:2n6, C20:4n6 (p<0.01) and C18:3n3 (p<0.05) than gilts in intramuscular fat.

This study was conducted to determine the effect of dietary whole-crop barley silage on average daily feed intake, average daily weight gain, velvet antler yield and economic efficacy in sika deer during growth. A total of 24 sika deer (initially 56.3 kg BW) of 24 months age were allotted in arrangement in a completely randomized design. The three treatments were: T1(hay diet), T2(whole-crop barley silage), and T3(50% hay+50% whole-crop barley silage). Concentrate feed were 1.5% feeding of body weight with all groups. Average daily weight gain of T3 was higher than those of others for the entire experimental period. Average daily feed intake of sika deer in decreasing order was as follows; T1>T3>T2. The velvet antler yield was highest in T3 group (315±112 g) compared with T1 (276±59 g) and T2 (283±108 g). However, there was no significant difference in average daily feed intake, average daily weight gain, velvet antler yield(p>0.05). In economic efficacy, T3 was about 15-29% higher than that of T1 and T2. In conclusion, the mixed feeding of 50% hay and 50% whole-crop barley silage was more effective in average daily feed intake, average daily weight gain, velvet antler yield and economic efficacy in sika deer

본 연구는 농산부산물을 이용한 발효사료의 급여효과를 알아보기 위해 비육 흑염소의 생산성 및 영양소 이용률을 조사하였다. 증체조사를 위한 사양시험은 거세흑염소 24두를 이용하여 처리구당 6두씩 30일 수행하였고, 소화율시험은 거세흑염소 12두를 공시하여 처리구당3두씩 라틴방각법으로 실시하여, 처리구는 대조구(배합사료 및 볏짚 급여구)와 3개의 시험구(발효사료와 볏짚 급여구)로 각각 배치하였다. 일당증체량은 대조구가 가장 높았고, T3구가 가장 낮았다(p<0.05). 1일 두당 건물섭취량 과 유기물섭취량은 시판사료를 급여한 대조구가 각각 718.8과 680.9 g, 농산부산물 첨가구가각각 634.2~699.2와 602.8~660.4 g으로 나타나농산부산물 중 미강 첨가구가 높을수록 섭취량이 낮아지는 경향으로 나타났다. 건물과 유기물 소화율은 대조구가 농산부산물 첨가구보다유의하게 높았고(p<0.05). 시험구간에는 미강을30% 첨가한 T3구가 가장 낮았다(p<0.05). 질소축적률은 대조구와 T1구가 유의하게 높았다.따라서, 본 연구의 결과 농산부산물을 이용한발효사료(T1과 T2구)는 시판사료를 급여한 대조구와 비교 시 증체는 86~90%, 건물소화율은91.7~93.1%의 수준을 보였으며, 질소이용성은대등한 수준을 보였다. 그러나 미강의 첨가 비율이 높아질수록 사료효율 저하가 우려되므로조지방 함량을 5.0% 이하로 배합하는 것이 필요하다 판단된다.

We investigated the effect of glutathione supplementation on body weight gain, feed intake, velvet antler yield and economic analysis in elk bulls. A total 14, 2-year old male elks were divided into 2 groups with control or glutathione treatment. Elks were fed concentrate feed at the level of 1.5% relative to body weight (3.1 kg). and allowed to consumed hay as roughage ad libitum. Glutathione was supplemented at the level of 6 mg/kg. Average daily gains (ADG) for 2-years old elks were 234.1± 7 and 247.6±22 kg in control and glutathione fed groups, respectively. Treated group had higher ADG than control (p<0.05). Individual daily DM intakes were 5.34±0.70 and 5.64±0.71 kg in control and glutathione supplemented groups, respectively. Glutathione-fed group showed an additional intake of 298 g on an average. Production of velvet antlers for elk yearlings was 4,229±720 g and 4,653±960 g in control and glutathione supplemented groups respectively. Analysis of economics efficiency revealed 8% higher revenue index in glutathione supplemented groups. In conclusion, glutathione supplementation showed increase of DM intake and ADG in elk bulls, and could also increase velvet antler production.

We investigated the effect of glutathione supplementation on feed intake, body weight gain, velvet antler yields and economics of elk yearling. Fourteen elk yearlings were divided into 2 groups. Seven yearlings in each group (control and treatment) were fed with 1.5-2.5 percent body weight (%BW) of concentrate feed for elk, voluntary intake of hay as roughage and 6 mg/kg body weight (KBW) of glutathione. The results were as follows. Average daily gain (ADG) for control elk yearlings for first 1.5 month was 0.46 kg, while that of glutathione supplemented was 0.55 kg. Although glutathione fed group had higher ADG compared to control group (p<0.05), ADG after 1.5 month showed no difference. In spring, daily DM intake per elk yearlings was 3.98 and 4.24 kg for control and glutathione supplemented groups, respectively. The statistical differences in feed intake between two groups were not observed. However, feed intake tends to increase in glutathione fed group. Production of velvet antlers for elk yearlings were 911±256 and 1066±357 g for control and glutathione supplemented groups, respectively. Statistical difference between two groups was not observed due to the high variation. In economic analysis, additional 109,110 KRW per head for the cost of glutathione resulted in 2 percent higher revenue index due to the increased antler production. In conclusion, feeding glutathione to elk deers effectively increased DM intake and ADG of elk yearlings. Glutathione supplementation in feed might increase velvet antler production as well as ADG.

본 연구는 조사료원으로 청보리 사일리지 급여시 농후사료 급여수준이 육성기 흑염소의 가소화 영양소 섭취량, 영양소 이용율 및 질소 축적율에 미치는 영향을 조사하였다. 시험구는 4처리구 (볏짚+농후사료 체중의 2.0%, 청보리 사일리지 + 농후사료 체중의 2.0%, 체중의 1.5%, 체중의 1.0%)로 나누어 처리구당 3두씩 라틴방각법으로 시험을 실시하였다. 시험기간 동안의 1일 두당 가소화 조단백질 섭취량은 대조구, 청보리 사일리지에 농후사료를 각각 체중의 2.0과 1.5% 급여구가 농후사료를 1.0% 급여구 보다 유의하게 높았다(p<0.05). 가소화 NFC 섭취량은 청보리 사일리지와 농후사료를 체중의 2.0% 급여구가 가장 높았고, 농후사료를 1.0% 급여구가 가장 낮았다 (p<0.05). 일당 증체량은 청보리 사일리지+농후사료 2.0%, 청보리 사알리지+농후사료 1.5%, 볏짚+농후사료 2.0%, 청보리 사일리지+농후사료 1.0%, 순으로 유의하게 낮아졌다(p< 0.05). 건물소화율은 청보리 사알리지와 농후사료를 1.5% 급여구가 대조구 보다 유의하게 높게 나타났다(p<0.05). 질소축적량은 대조구와 청보리 사일리지에 농후사료를 각각 체중의 2.0과 1.5% 급여구가 농후 사료 1.0% 급여구보다 유의하게 높았다(p<0.05). 이러한 결과를 종합적으로 고려할 때 청보리 사일리지를 조사료원으로 급여시 육성기 흑염소의 생산성과 효율적인 영양소 이용을 위한 농후사료 급여수준은 1.5%가 적정한 것으로 사료된다.

A gregarine parasite (Apicomplexa: Protozoa) was observed in the population of daikon leaf beetle, Phaedon brassicae Baly, (Coleoptera: Chrysomelidae) in Daegwallyeong. Gregarines are well known species-specific parasites of various Arthropoda. Based on 1.727kb of 18S rDNA sequence (FJ481523), this gregarine species was grouped in eugregarine and 5.258kb of full length rDNA replicon was cloned. We also observed interaction of tropozoite or gamonto of gregarine and epithelium of host midgut using scanning electron microscope. Although development of the infected host delayed half day in every larval stage, there was no significant difference in the development of daikon leaf beetle whether it is infected or not. Therefore, this gregarine parasite is not promising candidate for bio-insecticide in daikon leaf beetle.

It has been reported that light-emitting diodes(LED) can be used in the treatment of oral diseases. Although bio-stimulatory effects of LED irradiation such as promotes stimulation of wound healing have been well known, there are few reports about molecular mechanism associated with cell cycle by LED irradiation. The purpose of present study was to examine the molecular event in cell cycle of LED irradiation on primary human gingival fibroblast(hGF) in vitro. The source of light for irradiation was a continuous-wave LED emitting at a wavelength of 635nm, and manufactured that energy density was 5mW/cm2 on sample surface. The hGF were irradiated for 1 hour at 37℃ in 5% CO2 humidified chamber. Experimental samples were acquired at 0 (right after irradiation), 8 and 24 hour after irradiation. To investigate the molecular mechanisms associated with cell cycle, growth phase was determined by flow cytometry and mRNA expression of cyclin A, cyclin B, cyclin D1, cyclin E, cdc2, PCNA, p18, p27, p21, and p53 were determined by real time RT-PCR. Flow cytometric analysis demonstrated the percentage of cells in the G1 and S phase were decreased, but the G2 phase increased, which showed cells irradiated by LED were transitioned from S to G2 phase. For mRNA expression, cyclin B, cdc2, PCNA and p53 were increased at 0 hour after irradiation, and most of cell cycle molecules were increased at 8 hour after irradiation. At 24 hour after irradiation, cyclin A, cyclin E, PCNA and p18 were increased. Taken together, LED irradiation induced proliferation of hGF cells through transition from S to G2 phase.

As for the performance estimation of the AS/RS(Automated Storage/Retrieval System) most research assumes the AS/RS machine performs only either single command (SC) or dual command (DC) at each operation, and in addition, the type of requests is known in advance, which are not adequate in the real system. In this paper, we propose a stochastic approach for the performance estimation of a unit-load AS/RS. We assume that the service time when the AS/RS performs single command is differently distributed from that of dual command. Especially, we obtain the steady state probability distribution of the numbers of storage and retrieval commands waiting in the queues at each service completion epoch.
