The purpose of this study was to investigate the difference of the visual evaluation about Clothing form and the surface image of detail. This study consists of pre-experiment for selecting the method of expression among detail which shows difference of the image and main experiment for identifying the clothing image as clothing form and the suface image of detial. Main experiment is made of factorial design for three variables-clothing form (H-line, A-line, V-line, X-line), detail (frill, tape), direction (width, length). Questionaire consists of 24 semantic differential scale expressing clothing form and detail. The subjects were 100 female students majoring in clothing and textile.7he data were analyzed by Frequencey, Factor analysis, Anova, scheffe's test and MCA method. The major findings were; 1) The image of clothing form and the surface image of detail were composed of 5 factors; attractiveness, prettiness, attention, modern, young. 2) For the visual evaluation of clothing form as the surface image of detail, there were significant differences in prettiness and attention factors. For the pretty and attentive image, we should express by the image of frill. 3) For the visual evaluation of the image of detail as clothing forms variation, there were significant difference in prettiness by A-line and X-line. 4) For the effect of clothing form and the surface image of detail, main effect was significant in attractiveness, prettiness, attention, modern factor. For the pretty image of clothing, it will be expressed by the image of frill and A-line, X-line. For the attentive image of clothing, it will be expressed by the image of frill and V-line. For the modern image of clothing, it will be expressed by the image of tape and V-line.

A factorial experiment was conducted to assess nutrient utilization by growing lambs maintained on three levels each of digestible energy (high: HE, medium: ME, low: LE) and protein (high: HP, medium: MP, low: LP) in nine combinations (HEHP, HEMP, HELP, MEHP, MEMP, MELP, LEHP, LEMP, LELP). The experiment was conducted during the hot season in a semiarid location. Daily dry matter intake (DMI) was similar in all the groups in terms of unit body weight or metabolic body size. Digestibility of DM and nitrogen free extract increased (p<0.01) from low to medium and high energy regimen while the CF digestibility followed a reverse trend. The digestibility of crude protein (CP) decreased from high to medium and low protein regimens while it was similar in terms of energy variation. Nitrogen intake was higher in high followed by medium and low protein regime while fecal and urinary nitrogen loss were similar in all the treatment groups. Lambs in all the three levels of protein were in positive N balance and percent N retention was higher (p<0.01) in high followed by medium and low protein levels whereas it was similar in terms of energy variation. Initial body weight was similar in all the groups while final weight, total gain in the experiment and average daily gain (ADG) were higher in high than medium and low energy regimens. It is concluded that crossbred lambs required 75.1 g DM, 9.6 g CP, 6.3 g DCP and 711 KJ DE/kg W $^{0.75}$or 11.0 g CP/MJ DE or 7.2 g DCP/MJ DE for 93 g average daily gain in a hot semiarid environment.

This study was purposed to investigate the efficiency of protein utilization of rapeseed meal (RSM) and formaldehyde-treated RSM (TRSM) by sheep, and their influence on performance of growing heifers. Experiment 1 was conducted according to a double $3{\times}3$ Latin square design involving sex yearling Hu Sheep and three experimental diets. All diets contained 600 g ammoniated rice straw and 200 g concentrate mixture. Three dietary treatments were: (1) 100 g RSM + 40 g soybean meal (URUS), (2) 100 g TRSM + 40 g soybean meal (TRUS) and (3) 100 g TRSM + 40 g treated soybean meal (TRTS). Apparent nitrogen digestibility was significantly higher for diet TRUS than that for URUS or TRTS (p<0.05), but with no significant difference between URUS and TRTS (p>0.05). Proportion of nitrogen retention (NR) to the digestible nitrogen intake for diet TRUS and TRTS was 25.57 (p<0.05) and 23.44% (p<0.05) higher than that for URUS respectively. As a result, proportion of NR to nitrogen intake for diet TRUS and TRTS was 34.74 (p<0.05) and 23.78% (p<0.05) higher than that for URUS respectively. Experiment 2 was conducted with 59 Holstein heifers. They were 12-20 months of age at the start of the trial. The experiment was a $2{\times}2$ factorial trial in which the heifers were given the ammoniated rice straw ad libitum and 1.5 kg hay, and supplemented with either RSM or TRSM at a daily allowance of 1.2 or 1.8 kg per day. The live weight gains for heifers receiving 1.2 and 1.8 kg/d of RSM or TRSM were 0.491 and 0.556 or 0.564 and 0.665 kg/d, respectively. The results suggest that formaldehyde treatment can effectively improve the efficiency of protein utilization of rapessed meal and cattle's performance.

유머를 유발하는 핵심요인이 불합치라는 것에서는 많은 연구자들의 견해가 일치하지만, 불합치를 유발하는 상이한 스키마들의 활성화에서는 다른 견해를 보인다. 스키마의 활성화와 관련된 견해들 중에서 대비되는 두 견해에는 동시 활성화 견해(concurrent activation view)와 선택적 활성화 견해(selective activation view)가 있다. 이 연구에서는 유머텍스트 처리에서 상이한 두 스키마들이 어떻게 활성화 되는지를 경험적으로 검증함으로써 대비되는 두 견해를 살펴보고자 하였다. 실험은 유머 텍스트를 기저-도입-불합치-해소의 4단계로 구분하여 시행하였고, 불합치는 존재하되 해소부분을 조작한 대조텍스트를 사용하였다. 실험에서는 문맥에 부합하는 스키마를 S1, 부합하지 않고 유머의 참 뜻을 나타내는 스키마를 S2라 명명하였다. 실험결과 불합치 단계에서 활성화된 스키마들이 해소 단계에서도 여전히 활성화되고, 불합치 단계에서의 S1, S2 모두 해소단계의 S1, S2와 통계적으로 유의한 차이를 보였다. 이는 불합치 단계에서는 하나의 스키마가 다른 스키마를 억제할 것이라고 가정하는 선택적 활성화 견해와는 모순되는 것이다. 이 연구의 결과는 유머 텍스트를 처리하는 과정에서 상이한 스키마들은 동시에 활성화됨을 시사한다.

An experiment was conducted to determine the effects of dietary energy and protein on performance and carcass composition of broilers under heat stress during the growing period (3-6 weeks). A factorial arrangement of three levels of energy (3.0, 3.2 and 3.4 kcal/g), three levels of protein (18, 20 and 22%), an two rearing temperatures were used in this study. Groups of birds were kept under moderate temperature ($24{\pm}1^{\circ}C/24h$) or hot cycling temperature ($26-34^{\circ}C/6h$, $34{\pm}1^{\circ}C/12h$, and $34-26^{\circ}C/6h$). Body weight (BW), weight gain (WG), feed intake (FI), feed conversion (feed : gain) (FC), carcass weight (CW), carcass yield (YP), breast meat (BM), abdominal fat (AF), drumsticks (DS), and thighs (TH) percentages were determined at the end of the experiment. Hot cycling temperature significantly (p<0.05) decreased BW, WG, FI, CW, and BM, increased FC, YP, DS, and TH but did not affect AF. High energy significantly (p<0.05) increased BW, WG, CW, YP, AF, and TH, decreased FI and FC but did not affect BM or DS. This improvement was observed only under moderate temperature resulting in significant (p<0.05) energy by temperature interaction. High protein significantly (p<0.05) increased BW, WG, CW and BM, decreased AF but did not affect FI, FC, TP, DS, or TH. There were no significant protein by temperature interactions for any of the parameters tested except CW. It is concluded, under the conditions imposed in this experiment, that increasing dietary energy did not alleviate the depressing effect of heat stress while increasing dietary protein up to 22% improved the performance of broilers irrespective of rearing temperature.

The purpose of this study is to investigate the effect of tone-on-tone coloration on the visual images of traditional Korean dress. The materials in the experiment developed for this study were made up of various stimuli and the response scales for each stimulus. The stimuli were 48 color pictures with various combination of colors, in which the tones of jackets and skirts were manipulated by computer drawing. 24 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate each image. The subjects were 576 female students in Jinju City. This experiment was based on the $3{\times}4{\times}4$ factorial designs: color (red, yellow and green), jacket tone (vivid, light, dull and dark) and skirt tone (vivid, light, dull and dark). The results of the study can be summarized as follows; Impression factor of the stimuli consisted of the 5 different dimensions - youthfullness and activity, attractiveness, gracefullness, visibility, and tenderness. The colors and the tone of jackets and skirts used in this experiment influenced 5 impression dimension by interaction of two valuables or working independently. Yellow and green with vivid or light tone had an effect on the formation of youth and activity image, and dark-light combination had an effect on the formation of attractiveness image. In case of green color, light tone of a jacket and vivid or dull tone of a skirt affected gracefulness, while yellow has no impact on visibility image regardless of skirt tone. Red and yellow with vivid or light tone were a factor to decide tenderness.

Escherichia coli (E. coli) and Salmonella enterica (SE) infections in pigs are major source associated with enteric disease such as post weaning diarrhea. The aim of this study was to investigate the effects of Pediococcus pentosaceus in weaned piglets challenged with pathogen bacteria. In Experiment.1 90 weaned piglets with initial body weights of 8.53 ± 0.34 kg were assigned to 15 treatments for 2 weeks. The experiments were conducted two trials in a 2 × 5 factorial arrangement of treatments consisting of two levels of challenge (challenge and non-challenge) with E. coli and SE, respectively and five levels of probiotics (Control, Lactobacillus plantarum [LA], Pediococcus pentosaceus SMFM2016-WK1 [38W], Pediococcus acidilactici K [PK], Lactobacillus reuteri PF30 [PF30]). In Experiment.2 a total of 30 weaned pigs (initial body weight of 9.84 ± 0.85 kg) were used in 4 weeks experiment. Pigs were allocated to 5 groups in a randomized complete way with 2 pens per group and 3 pigs per pen. Supplementation of LA and 38W improved (p < 0.05) growth performance, intestinal pathogen bacteria count, fecal noxious odor and diarrhea incidence. In conclusion, supplementation of 38W strains isolated from white kimchi can act as probiotics by inhibiting E. coli and SE.

One metabolism trial(Experiment I) and another respiration trial(Experiment II) were conducted to investigate the effects of dietary fiber supplementation(20% wheat bran) on the water balance, blood acid-base balance, body temperature, and metabolic rate of heat-stressed adult roosters. In Experiment I, twenty 20-wk-old SCWL roosters(BW 1.6 kg) were randomly alloted to 4 treatments with 5 birds per treatment and one per replicate. The 4 treatments were consisted of two temperature(21~22˚C vs. 34~35˚C) and two dietary fiber treatment(0% and 20% wheat bran), making Experiment I a 2x2 factorial. After 4 d of preliminary period, birds we subjected to 3-d collection period. Sixteen 20-wk-old SCWL roosters(BW 1.6 kg) were employed Experiment H, with two temperature(21~22˚C vs. 34~35˚C) and two wheat bran levels(0% and 20%). Brids were housed in individual metabolism cages under normal temperature(21~22˚C), at fed one of the experimental diet. After 4 d of preliminary period, a respiration trial with open-circuit gravimetric respiratory apparatus was carried out for each bird for 6 h, one by one, normal(20~21˚C) and hot(34~35˚C) temperatures. The ANOVA test and comparisons among treatment means were done at 5% probability level for both experiments. Results obtained from Experiment I and, II were summarized as follows, 1.The amounts of DM intake and excretion were significantly(P<.05) decreased by heat stress. The DM intake was not affected by the addition of 20% wheat bran, however, the amount of DM excretion was significantly increased by the high fiber diet. Thus, the DM metabolizability decreased significantly by the addition of 20% wheat bran. 2. The heat-stressed roosters increased the water intake and excreta moisture content significantly. Although not significant, the water intake tended to increase in roosters fed the 20% wheat bran diet. 3. The amounts of total water input and evaporative water loss were increased significantly by heat stress, and the addition of 20% wheat bran did not exert any influence on the total water input and evaporative water loss. However, roosters fed the 20% wheat bran diet increased the excreta water output significantly. 4. Neither the heat stress nor the dietary fiber did affect the blood pH, pCO2, and HCO$_3$- significantly. 5. The body temperature increased significantly by the heat stress. However, the high fiber deit failed to decrease the body temperature. 6. The heat-stressed roosters decreased the 02 consumption and C0$_2$ production, and increased the evaporative water loss significantly. However, the high fiber diet did not exert any infulence in this regard. It appears that the beneficial effect, if any, of high fibrous diet during heat stress episode may be due to the increased heat loss through the enhanced excreta water.
