The purpose of this study is to develop a decision model that helps manufacturers and retailers determine the optimal timing of markdown in order to maximize their profit. An optimal timing decision model was developed based on three steps; conjoint measurement, scenario analysis and simulation. Data were collected from the sample of 149 out of 170 undergraduate and graduate students in Seoul in 1997. From the Jeans market, 8 brands; Levi's, lee, Guess, Calvin Klein, Pintos, Get used, MFG, and Basic, were selected as competitors for this study. In the conjoint measurement, respondents estimated the level of preference, from 1 to 100, for each item in which brand, price, style, and colors were used to explain product characteristics. Then, in order to reflect competitive situation in Jeans market, four types of scenarios were developed. In each scenario, simulations were applied to decide optimal timing of markdowns that leads to maximal profitability and sales volume. The profit was calculated based on the equation; Profit = Jean's market volume x market share of each brand - cost, where market volume was obtained by integral calculus for market utility function, and market share by logit value of part-worth from the conjoint analysis. For the purpose of the parsimony of the research, costs and the level of markdown were fixed to 30% of the regular price. In results, the optimal timing decision model identified 3 different types of brands. The brands that do not need to take markdown were Ievi's, MFG, and Basic Jeans characterized by the highest brand power and the highest price zone. The brands that needed to take early markdowns were Guess, Lee, Calvin Klein, and Get Used with the intermediate level of brand power and price. The brand that need late markdown was Pintos with the weakest brand power among the competitors and the lowest price. The optimal range of markdown remains for further research.

This systematic review focused on the efficacy of topical products in reducing temporomandibular joint disorder (TMD)-associated pain, in comparison to placebo or control interventions. The EMBASE, Web of Science, Cochrane Library, and MEDLINE via PubMed databases were searched for randomized controlled trials (RCTs) using topical interventions in adults diagnosed with TMD. The pain intensity was the primary outcome, and other clinical findings were the secondary outcomes. The risk of bias was evaluated according to the Cochrane's handbook. The search up to February 7, 2020 identified a total of 496 unduplicated references. Nine RCTs with 355 adult patients diagnosed with TMD were included. The meta-analysis did not show a significant reduction in baseline pain intensity in the nonsteroidal anti-inflammatory drug (NSAIDs) group, when compared to the placebo group (P = 0.288). One study demonstrated a statistically significant pain score decrease for Theraflex-TMJ compared to placebo after 10 d of treatment (P = 0.003) and follow-up, 5 d after the last application (P = 0.027). Ping On reduced pain at 4 weeks of application (P < 0.001) but not after 7 d of application (P = 0.136). In one study, cannabidiol (CBD) significantly improved the pain intensity compared to placebo (P < 0.001). However, no differences were found with capsaicin in the two studies (P = 0.465). Evidence was of low quality because the studies were considered as having an unclear or a high risk of bias and a small number of studies were analyzed. The evidence is not sufficient to support the use of topical NSAIDs and capsaicin, and limited evidence was found for Threraflex-TMJ, bee venom, Ping On, and CBD, with only one study reporting for each. Additional studies are recommended to validate these results.

Molten salt consisting primarily of eutectic LiCl-KCl is currently being used in electrorefiners in the Fuel Conditioning Facility at Idaho National Laboratory. Options are currently being evaluated for storing this salt outside of the argon atmosphere hot cell. The hygroscopic nature of eutectic LiCl-KCl makes is susceptible to deliquescence in air followed by extreme corrosion of metallic cannisters. In this study, the effect of occluding the salt into a zeolite on water sorption/desorption was tested. Two zeolites were investigated: Na-Y and zeolite 4A. Na-Y was ineffective at occluding a high percentage of the salt at either 10 or 20wt% loading. Zeolite-4A was effective at occluding the salt with high efficiency at both loading levels. Weight gain in salt occluded zeolite-4A (SOZ) from water sorption at 20% relative humidity and 40℃ was 17wt% for 10% SOZ and 10wt% for 20% SOZ. In both cases, neither deliquescence nor corrosion occurred over a period of 31 days. After hydration, most of the water could be driven off by heating the hydrated salt occluded zeolite to 530℃. However, some HCl forms during dehydration due to salt hydrolysis. Over a wide range of temperatures (320-700℃) and ramp rates (5, 10, and 20℃ min^-1), HCl formation was no more than 0.6% of the Cl^- in the original salt.

This study conducted a survey on jean pants that targeted males in the 20s in order to select preferred brands for skinny jean pants. Preliminary data for the pattern development of skinny jean pants was presented through functionality evaluation, appearance evaluation and pattern analysis. The results were as follows. 1. The result of survey targeting males in the 20s to select the design and brand name of jean pants showed that skinny jean pants were selected as the most favorite type of jean pants to wear; in addition, non-brand products and brand names such as Uniqlo and Levi's were also preferred. 2. The result of functionality evaluation showed that L brand received a high score in all items except for items regarding the knee circumference and mid-thigh circumference, S brand received a high score as well as a low score, and N brand received a low score in general. The result of appearance evaluation showed that L brand for the waist height and waist circumference, N brand for the brand crotch circumference, posterior crotch length and knee circumference, and S brand and N brand for the length of pants were preferred. 3. The result of pattern measurements analysis from the result of functionality evaluation showed that L brand provided a large pattern measurement for the waist height, L brand provided less ease due to small pattern measurements for waist circumference; in addition, N brand for the knee circumference and mid-thigh circumference were preferred. 4. The analysis result shows that a ease of 5cm based on the belly band which is 3.5cm below the belt width is proper for the waist circumference when designing a skinny jean pant pattern and 4cm for the hip circumference and 32.5cm for the ease of crotch circumference are proper, -0.4-0cm for the ease of mid-thigh circumference and knee circumference in consideration of human body measurements; therefore, 80.1-80.5cm for inseam as the length from the crotch height to the leg length, 25.7cm for vertical hip length and 53.0cm for crotch length are proper.

Even in this current high-tech industrial age, mythological imagination is considered important. Although each mythology scattered all across the world may have an insignificant origin, to understand that particular society fully, one must not mistakenly assume that the mythology itself is a production of a primitive mind. Ultramodern physics and futurology professor Freeman Dyson has also acknowledged this opinion. He insists that in order for human kind to survive into the far future it most keep in touch with its far past. Levi-Strauss also observes that mythology and science aren't a entirely separate domains. The scientific mind is regarded as a source of understanding the intrinsic qualities of mythology. Taking mythology and science as a binomial opposition, and only weighing their prospects, should be put to the past as we should recognize the need for mythology and science's qualitative unification. In this new point of view, regarding mythology as a meaningless irrationality should cease, while finding out why the inevitably related world of mythology needs metaphoric, ideological consideration. By utilizing 'Whale Rider' by Witi Ihimaera(2004) we will discover why our lives require an 'image' that is borrowed from our experience. The author, Witi Ihimaera, is originally from the Maori tribe, who approaches the world with a mythological imagination, which is not easy to understand with scientific thinking nor in modern civilization. When looking into the mythology of the ocean which still lives in modern civilization, while noting that the world is one, the author indicates that reality and unreality, nature and the super-natural, present and the past, science and fantasy, were not divided from the beginning. However, overtime humans have divided the borders. To do this, the author interprets the ancient emotions of the Maori tribe which have been traditionally accumulated in the group identity in a new literary way by introducing the Maori tribe's ancestral god, Paikia, who can converse with the ocean and the whales. This piece, which has been made into a movie and won awards in 5 international film festivals, including the Toronto International Film Festival, regards primitive emotions as a rational concept instead of an instrumental concept. Also these primative emotions are continuing their attempts to communicate with nature. Furthermore, it advises contemporary human beings who seek for eternal life to not exploit the cultural differences that have been formed naturally, and it is vital for human beings to transcend the ethnic boundaries and to think rationally. In the story, we can find "the dissimilar us" that philosopher E. Levinas mentioned in his sayings, which refers to responsible human beings who devote their lives for the sake of other people instead of fulfilling their own needs.

Objective: To evaluate the effects of the carmine cochineal-resistant spineless cactus genotypes cv. Orelha de Elefante Mexicana (Opuntia) and Miúda (Nopalea) on the intake and digestibility of nutrients, ingestive behavior, performance, and ultrasound measurements of growing lambs. Methods: Thirty-six male (non-castrated) Santa Inês lambs were used, with an average age of 6 months and an initial average weight of 22.0±2.9 kg. They were distributed in a completely randomized design with 3 treatments (Tifton hay, Nopalea and Opuntia) and 12 replications, using initial weight as a covariate. The experimental period was 86 days, with the first 30 days used for the adaptation of the animals to the facilities, diets and management, and the remaining 56 days used for evaluation and data collection. Results: The intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), total carbohydrates (TC), non-fibrous carbohydrates (NFC), and total digestible nutrients (TDN) showed a significant difference (p<0.05) as a function of the diets, with the Nopalea treatment (p<0.05) increasing DM intake (g/kg and % body weight [BW]), CP, TDN, and TC digestibility, whereas the Tifton hay diet led to a high (p<0.001) neutral detergent fiber corrected for ash and protein (NDFap) g/d intake, NDFap (BW %) and digestibility of said nutrient. There was no effect of treatments (p>0.05) on feeding time, however, rumination time and total chewing time were higher (p<0.05) for animals fed Tifton hay. The performance of the animals was similar (p>0.05). For the ultrasound measurements, Nopalea promoted an increase in the final loin eye area, compared to Tifton hay. Conclusion: The use of spineless cactus variety Miúda leads to the greater intake and digestibility of nutrients. The evaluated carmine cochineal-resistant spineless cactus genotypes are alternatives for semi-arid regions as they do not negatively affect the performance of growing lambs.

우리 사회가 날로 개방되고 경제, 사회 문화적으로 국제 교류가 활발해 지면서 문화 간 커뮤니케이션의 중요성이 그 어느 때보다도 부상하고 있다. 하지만, 우리 사회가 전통적으로 가진 단일민족의 이데올로기와 자문화 중심주의가 발전적인 국제 관계에 걸림돌로 작용하고 있는 실정이다. 본 연구에서는 우리 사회에 만연되고 있는 문화 간 커뮤니케이션의 장애요소를 진단하기 위해 뉴스 보도를 분석하고자 한다. 분석을 위해 올해 상반기 문화 간 커뮤니케이션 관련 뉴스로 가장 빈번히 보도된 '한류'와 '하인스 워드 신드롬'으로 불린 인종 문제 보도를 대상으로 하였다. 분석 대상은 2006년 1월부터 4월 15일까지 4개월간 일간지로는 동아일보, 조선일보, 중앙일보, 한겨레신문과 매일경제, 방송 뉴스로는 KBS, MBC, SBS의 9시, 8시 메인 뉴스를 대상으로 하였다. 이들 언론사의 한류와 인종관련 보도 전체를 대상으로 하였으며, 총 495개의 기사를 분석하였다. 이들 언론 보도에 나타난 문화 간 커뮤니케이션의 문제를 파악하기 위해 문화 연구 중 활발한 성과를 낸 내러티브 이론을 도입하여 분석하였다. 내러티브 이론은 한류와 인종 보도의 내면에 작용하는 허구성과 권력의 측면을 간파할 수 있게 해 준다. 특히 본 연구에서는 레비-스트로스의 구조 이론과 그레마스의 의미론을 중심으로 한 내러티브 분석을 통해 한류와 인종 보도가 보이는 탈문화적 팽창주의와 정체성의 문제를 밝혀 낼 수 있었다. 이들 문제는 보다 더 심층적 차원에서 우리 사회에 작용하는 욕망과 권력의 문제를 드러내는데, 포스트식민주의 이론을 도입하여 문제를 진단하고 해결방안을 모색하고자 하였다.

Objective: Evaluate the partial replacement of soybean meal with different protein sources in piglet feed during the nursery phase in terms of digestibility of feed, nitrogen balance, growth performance and blood parameters. Methods: Experiment I involved 24 crossbred entire male pigs with an initial body weight (BW) of $18.28{\pm}0.7kg$ and used a randomized complete block design consisting of 3 treatments (fish meal, FM; soybean protein concentrate, SPC; and soybean meal, SBM) and 8 replicates, with 1 pig per experimental unit. Experiment II involved 1,843 crossbred male and female pigs with an initial BW of $6.79{\pm}0.90kg$ and was based on a completely randomized design with a $2{\times}3$ factorial arrangement (2 sexes and 3 protein sources) and 13 replicates. Results: The results of Exp. I indicate effects (p<0.05) of dietary protein sources on digestible protein (FM, 17.84%; SPC, 16.72%, and SBM, 18.13%) and on total nitrogen excretion (TNE, $g/kg\;BW^{0.75}/d$) in which pigs fed with SBM-based feed had TNE values that were 5.36% and 3.72% greater than SPC and FM, respectively. In the Exp. II, there was difference (p<0.01) between sexes in the pre-starter I and starter phases, and total period in average daily feed intake (ADFI), which were greater in females, and between the protein sources, ADFI, final weight and daily weight gain. For urea in the pre-starter II and starter phases and glucose in the pre-starter II phase, there was a difference (p<0.05) between protein sources and between sexes, in starter phase in urea concentrations (females: 57.11 mg/dL and males: 50.60 mg/dL). Conclusion: The use of SBM as only protein source influences larger TNE ($g/kg\;BW^{0.75}/d$), reduces the growth performance of piglets and increases plasma urea concentrations in prestarter II phase.

Objective: This study was to assess the effects of different doses of an essential oil blend (EOB) on growth performance, diarrhea occurrence (DO), hematological and blood biochemical profile, intestinal morphometry, morphology and microbiology, relative weight and length of organs, digestive content pH, and liver antioxidant status in weaning piglets. Methods: A total of 135 barrows (7.09±0.29 kg body weight) were allotted randomly in a randomized complete block design based on body weight with nine replications and three animals per pen. Dietary treatments were a negative control (NC): basal diet; positive control (PC): NC plus 125 mg performance-enhancing antibiotic (enramycin 8%)/kg diet; NC plus 100 mg EOB/kg diet (EO100); NC plus 200 mg EOB/kg diet (EO200); and NC plus 400 mg EOB/kg diet (EO400). Diarrhea occurrence was monitored daily, and performance at the end of each phase. Results: Gain to feed ratio was greater (p<0.05) in starter II pigs fed EO400 and EO200 than in those fed EO100. Pigs fed EO400 had lower (p<0.05) DO than those fed NC and EO100 in the total period. Pre-starter II pigs fed NC had (p<0.05) lower serum total protein and plasma protein than pigs fed PC. Pigs fed EO100 showed smaller (p<0.05) mean corpuscular volume (MCV) than pigs fed EO400. Starter II pigs fed EO400 had (p<0.05) greater MCV and lower mean corpuscular hemoglobin and erythrocytes than those fed EO100. There was a greater concentration (p<0.05) of band cells for PC, similar to EO400 and EO200. Performance-enhancing antibiotic and EOB to diets increased (p<0.05) liver superoxide dismutase activity. Conclusion: Adding 200 and 400 mg EOB/kg diet decreased DO and was advantageous to hematological and blood biochemical profile and liver antioxidant status without being detrimental to growth performance and gastrointestinal health in nursery pigs.
