Data of 369 commercial pigs produced from YorkshrexLancrace (YL F1) sows crossed with either Duroc (D), Berkshire (B) or BerkshirexDuroc(BD F1) as a terminal sire were used for the comparison of carcass garde and real retail cut yield. The crosses were performed between May, 2004 and May, 2006 at three interrlated farms belonging to the Gyeongam pork brand. The average carcass weight, carcass backfat thickness, carcass rate, AB grade ratio, lean meat yield were 84.78±0.33kg, 20.72±0.237mm, 76.25±0.208%, 85.7% and 44.30±0.158%, respectively. The average weights of real retail cut were 10.32±0.062kg belly, 4.17±0.025kg boston butt, 3.88±0.022kg rib, 8.40±0.040kg picnic, 15.15±0.081kg ham, 6.44±0.043kg loin and 0.94±0.006kg tender loin. In comparisons of carcass traits among cross types, carcass weights and backfat thicknesses of YL(♀)×B(♂), YL(♀)×BD(♂) and YL(♀)×D(♂) were 85.73±0.516kg, 82.69±0.788kg and 84.79±0.603kg, respectively and 22.09±0.356mm, 20.33±0.543mm and 19.58±0.415mm, respectively. The YL(♀)×B(♂) cross showed the highest carcass weight and backfat thickness. The ratio of AB grade were 0.83±0.030% in YL(♀)×B(♂), 0.97±0.046% in YL(♀)×BD(♂) and 0.83±0.035% in YL(♀)×D(♂), and the YL(♀)×BD(♂) was higher than other two crosses. Weights of belly were 10.28±0.092kg in YL(♀)×B(♂), 10.59±0.133kg in YL(♀)×BD(♂) and 10.25±0.107kg in YL(♀)×D(♂). Consequently, the YL(♀)×BD(♂) cross showed the highest yield. In conclusion, there was no difference in carcass yield of commercial pigs derived from BD (F1) terminal sires with those from D terminal sires. However, weight of belly and AB grade ratio from BD (F1) terminal sires are higher than two others. Therefore, BD (F1) sire could be utilized as terminal one and contribute better profit for the pig industry.

School food services using environment-friendly agricultural products (E.F.A.E) have been promoted by school food service center (S.F.S.C) of each county in Chungnam. Since Dangjin S.F.S.C was established for the first time in 2011, 13 S.F.S.Cs have been established in 13 counties of Chungnam. 9 S.F.S.Cs of them have been managed directly by each county and 4 S.F.S.Cs of them managed by contracted cooperatives. Price deviation of 8 foodstuffs (rice, radish, spinach, cabbage, scallion, onion, garlic and potato) which are consumed much relatively was showed differently by counties. And in the average price of 8 foodstuffs, that of foodstuffs produced within the county was lower than that of produced in Chungnam and domestic. Also, the coefficient of variation of school foodstuffs was lower than that of retail market because S.F.S.C has procured school foodstuffs by contract cultivation between each S.F.S.C and producers. Contract cultivation effected on E.F.A.E price stability and producers' farm income.

The Electronic Shelf Label (ESL) is an alternative to the paper price label attached to merchandise shelves and is attracting attention as a retail IoT infrastructure that will lead the innovation of offline retail outlets. In general, when introducing a substitute product, the company tends to consider the financial factors such as the efficiency of the investment cost compared to the existing product or the reduction of the operating cost. However, considering only financial factors in the decision-making process, it may not properly reflect the various values associated with corporate strategy and the requirements of stakeholders. In this study, 8 evaluation items (Investment Cost, Operating Cost, Quality Level, Customer Management, Job Efficiency, Maintenance, Functional Expandability, and Store Image) based on BSC's 4 perspectives (Financial, Customer, Internal Business Process, Learning & Growth), and using AHP (Analytic Hierarchy Process) to measure the priorities of evaluation items for domestic small supermarket employees. As a result of the research, priority was given in order of Customer, Learning & Growth, Internal Business Process, and Financial aspects among the evaluation items for adopting the price label, and the electronic price label was supported with higher importance than the paper price label. In contrast to the priorities of the financial aspects of most prior studies, the items of Learning & growth and customer perspectives have relatively high priorities. In particular, respondents classified by job group, The priorities of the 8 evaluation items were different among the groups. These results are expected to provide implications for both companies (retail outlets) and ESL providers (manufacturers and service providers) who are considering the introduction of ESL.

This study identified types of information source, and explored a path model for consumer information search by shopping attributes in the context of online decision making. Participants completed self-administered questionnaires during regularly scheduled classes. A total of 219 usable questionnaires were obtained from respondents who enroll at universities in the southwestern region of the United States. For data analysis, factor analysis and path model estimation were used. Consumer information source was classified into three types for online clothing purchases: Online source, Offline retail source, and Mass media. Consumers were more likely to rely on offline retail source for online clothing purchases, than other sources. In consumer information search by shopping attributes, online sources were more likely to be related to transaction-related attributes(e.g., incentive service), whereas offline retail source(e.g., displays in stores, manufacturer's catalogs and pamphlets) were more likely to be related to product and market related attributes(e.g., aesthetics, price) when purchasing clothing online. Also, the path model emphasizes the effect of shopping attributes on traditional retailer search behavior, leading to online purchase intention for clothing. This study supports consumer information search by attributes, and discusses a managerial implication of multi-channel retailing for apparel.

In today's world, the ability to adapt to the rapidly changing environment is fundamental to the survival and success of any organizations. This is particularly true for the Korean retailing industry which is in the throe of sweeping developments. Against the backdrop of an increasing importance of the environmental factors, it is imperative to look into what efforts are required of corporate enterprises in order to achieve successful long-term partnerships between and among the parties involved in the retail value chain. In spite of the critical importance of the need to understand the environmental factors and their influences on the retail value chain, a serious theoretical and empirical study into this subject has never been conducted. Moreover, previous research has overlooked the various mechanisms influencing the value chain in terms of ,control strategy' and 'control structure'. The purpose of this study is to investigate the direct and indirect modes of influences environmental dynamism exerts on opportunism, one of important relationship factors. This study particularly delves into the indirect modes of influence in terms of control strategy (control mechanism) and control structure (bureaucratic structuring). To this end, a survey research has been conducted of 200 suppliers in business relationships with Korean hypermarket retailers. The survey results show that environmental dynamism has a positive correlation with the opportunism of suppliers. In addition, the control mechanisms such as monitoring and incentives employed by retailers, in turn, have an indirect influence on the opportunism of suppliers. In other words, the monitoring of retailers has a positive correlation with the opportunism of suppliers, while the use of bureaucratic structuring has a negative correlation with opportunism. This study discusses how both retailers and their suppliers should respond to the domestic retail business environment with highly dynamic characteristics, in order to achieve a long-term win-win partnership with one another. It also presents ideas to retailers with regard to what kinds of management strategies and management efforts required to effectively control the opportunism of suppliers.

This paper examines the relationship between the locational patterns of global and domestic stores. Objective corporation for this research is the Daiei Inc., which is multinational retail corporation of general merchandise store industry. Used data are For the Customers and 1997 Annual Report published by the Daiei Inc. in 1997, and Worldwide Branch Location of Multinational Companies published by the Gale Researchy Inc. As a result it is recognized that the headquarters of supermarket companies are not necessarily established in the largest city of the store networks. In addition, the chani o stores does not always correspond to the economic territory area of a city or a regional urban system. Usually, supermarkets are established first one after another around the headquarter, so that the store network becomes intensive. Moreover, supermarket companies exhibit a tendence of expanding after having increased density of their stores in their indigenous regions. It seems that supermarket companies try to lay the foundation of their operation firmly on their indigenous regions, while they expand the store network into neighboring regions in order to enlarge their profits. This phenomenon appears more and less partly in the location of oversea purchasing offices. First oversea office location appears in neighboring countries whose headquarter is located in Japan. Another oversea office location is established in higher order city of another continent. Usally after the number of oversea offices increases in their headquarter's neighboring region, the oversea office network exhibits a tendency of expanding in another continents. in addition, network of oversea offices does not always correspond with world urban system. The location of oversea offices is formed, after internalization of supermarket stores was established in Japan. And when increasing rates of supermarket stores was low in Japan, number of oversea offices increased.

The effects of dietary vitamin E and selenium(Se) supplementation on meat color stability in M. Longissimus of Hanwoo(Korean native cattle) bull beef during retail display(5$^{\circ}C$, 1,200 lux) were investigated. Experimental groups were divided into control(Vit E 27 IU/head/day, Se 0.09 mg/head/day), Vit E (2,500 IU/head/day), Se(20 mg/head/day), Vit E+Se(Vit E 2,500 IU/head/day, Se 20 mg/head/day) groups. CIE a*(redness), chroma(C*) values, oxymyoglobin(%) and R630-R580 were significantly (p<0.05) decreased among the 4 treatment groups during retail display, in particular, those values decreased more rapidly in the control group. The metmyoglobin (%) of 0 day(before storage) was not significantly (p<0.05) different among the 4 treatment groups. However, the rate of metmyoglobin accumulation during storage increased more rapidly in the control group. Therefore, discoloration in the control group was more accelerated compared to the other groups. TBARS(thiobarbituric acid reactive substances) which represent lipid rancidity was significantly(p<0.05) lower in Se and Vit E+Se groups than in the control and Vit E groups. Reducing ability of 0 day(before storage) was significantly lower in the control group than in the other groups, and it decreased more rapidly in the control group after 3 days of storage. Consequently, Se-supplemented groups(Se and Vit E+Se groups) were more resistant to lipid oxidation than were the control and Vit E groups. The stability of meat color and myoglobin forms(%) were significantly (p<0.05) higher in Vit E, Se and Vit E+Se groups than in the control group, but there were no difference among Vit E, Se and Vit E+Se groups.

A total of 127 Korean native black pigs(gilt 30, boar 97) were used to investigate the carcass properties, yields of retail cut and meat quality. The average live weight, chilled carcass percentage and retail cut percentage used in this study were 74.69kg, 71.14% and 61.09% for boar, and 75.5kg, 73.88% and 56.25% for gilt, respectively. Although gilts were higher in live weight and chilled carcass percentage whereas lower in retail cut percentage when compared to boars, there was no significantly difference between gender(p<0.05). Gilts had higher fat contents than boars regardless of weight range groups. Protein contents increased as slaughter weight increased for gilt and boar groups. Gilts contained high intramuscular fat contents had significantly lower Warner-Bratzler shear force(WBS) and water holding capacity(WHC) when compared to boar in the same weight range group(p<0.05). There was no significantly different in meat color(p>0.05) although gilts had higher L(lightness), a(redness) and b(yellowness) values when compared to the same group of boar. From the result of this study can be used for the grading guideline and quality evaluation standard of Korean native black pigs by gender and live weight.

In this study, a total of 256 samples of retail raw meats (beef, pork and chicken) and sashimi were investigated for the presence of Enterococcus faecalis and Enterococcus faecium. We isolated a total of 117 E. faecalis and E. faecium from the samples, with contamination rates ranging from 18.8% for sashimi samples to 68.8% of chicken samples. E. faecalis was the predominant species recovered from all of the retail raw meats beef (42.2%), pork (42.2%), chicken (65.6%) and sashimi (12.5%). Among 117 isolates, 61 isolates (52.1%) were resistant to tetracycline, 32 isolates (27.4%) were resistant to erythromycin, 23 isolates (19.7%) were resistant to chloramphenicol, 16 isolates (13.7%) were resistant to ripampin, 10 isolates (8.5%) were resistant to gentamycin, 9 isolates (7.7%) were resistant to ciprofloxacin and 1 isolate (0.9%) was resistant to ampicillin and penicillin G. No resistance to amoxicillin + clavulanic acid and vancomycin was observed. Although no strain was resistant to vancomycin, the vanB gene was observed in 9 of 117 of Enterococcus (7.7%) demonstrating potential risk of vancomycin-resistant Enterococcus (VRE). Our results indicate that E. faecalis and E. faecium were highly prevalent in retail raw meats, but most strains were sensitive to tested antibiotics.

The purposes of this study were to document the fashions adopted by young women in the United States in the 1980s and to explore if and how the dynamic shifts toward postmodernist values influenced those fashion trends. Fifteen U.S. women who were college students in the 1980s were interviewed for the study. In analysis of the data, we focused on social changes during the 1980s and the cultural impact of postmodernism vs. modernism as influential factors. Both postmodern and feminist ideas challenged the mainstream cultural framework of capitalism. U.S. women's styles and behaviors concerning dress reflected characteristics of postmodern consumption patterns, which include nostalgia, ethnic dress, androgyny, eclectic and novel clothing combinations, surprising or humorous appearance, and nonconformity. Despite the critique of conformity and conservatism in dress that had emerged in the 1960s and remained in at least minority or subversive trends, the importance of brand names and designer labels increased in mainstream fashion. This study helps us better understand the dynamics of fashion as it reflects societal and value changes in a transitional time in history.
