As global partnership is recently getting important in order to establish supply chain network in global managing environment, companies tend to improve quality and warranty in SCM(Supply Chain Management) by certifying ISO(International Organization for Standardization). This research investigated structural relationship how strategic and operational ISO application level and trust, immersion, collaborative factors in partnership process affect to companies business performance. This research was surveyed with 147 manufacturing companies in South Korea and conducted empirical analysis using Structural equation model. The research hypothesis and model was derived from the basis of existing theory and empirical research, and obtained the following results. Firstly, the strategic ISO level showed positive(+) effect on trust and immersion factor. Second, the operational ISO level showed positive(+) effect on trust and collaborative factor. Third, trust factor in the partnership process showed positive(+) effect on immersion factor. Lastly, collaborative factor in partnership process showed positive(+) effect on companies business performance. Implication for this research is that companies must consider ISO application in establishing partnership and companies require prolonged effort using trust, immersing, collaborative factors into partnership process to improve business performance.

RFID is an automatic identification technology that can control a range of information via IC chips and radio communication. Also known as electronic tags, smart tags or electronic labels, RFID technology enables embedding the overall process from production to sales in an ultra-small IC chip and tracking down such information using radio frequencies. Currently, RFID-based application and development is in progress in such fields as health care, national defense, logistics and security. RFID structure consists of a reader that reads tag information, a tag that provides information and the database that manages data. Yet, the wireless section between the reader and the tag is vulnerable to security issues. To sort out the vulnerability, studies on security protocols have been conducted actively. However, due to difficulties in implementation, most suggestions are concerned with theorem proving, which is prone to vulnerability found by other investigators later on, ending up in many troubles with applicability in practice. To experimentally test the security of the protocol proposed here, the formal verification tool, CasperFDR was used. To sum up, the proposed protocol was found to be secure against diverse attacks. That is, the proposed protocol meets the safety standard against new types of attacks and ensures security when applied to real tags in the future.

In order to evaluate the evaluation of bi-national products, this study was classified according to product category similarity. In addition, by comparing the types of stores, we tried to suggest alternatives that can be practically applied to companies producing composite origin products. For this purpose, this study is applied to the analysis of bi-national product by product categories, such as public luxury, public luxury, private luxury, and private necessity, based on the psychological bases of consumers. The types of stores are divided into department store/direct store, outlet/discount store to elaborate measurement. As a result of the verification, it was found that brand evaluation and store evaluation had interactive effects depending on product type and store type. Specifically, in the case of public luxury goods, outlets/discount stores in both brand evaluation and store evaluation showed positive evaluation than department store/direct store. In the case of private necessity, there was no significant difference in brand evaluation, but in store evaluation, department store/direct store was confirmed that they had a relatively positive evaluation than outlets/discount stores. As a result, it was verified that consumers' evaluations can be changed according to the type of sales store for each product.

This study was conducted to establish a comprehensive grading guideline for poultry. Guidelines for sampling size and grading were determined on the basis of survey data obtained from chicken processing house. Results were summarized as follows : For application unit, most chicken processing house preferred lot unit to farm unit. Most processing house did not want the total survey method, but selection sampling. At the beginning of the grading system, chicken processing house wanted to apply the system to a particular lots for which the company requests. There were much suggestions for grading not only portion meat, but also whole chicken. Bigger processing house preferred no. $8\~12$ to be graded. Most of large-scale processing houses used more than 81 volts for stunning and cooling tanks by soaking. For shipping chicken, Large-scale processing houses used both individual and box packing while small ones only used box packing.

Hazard Analysis Critical Control Point System (HACCP) is recognized worldwide as a science-based and systematic approach for food safety. This has been initiated to establish the HACCP system in Korean slaughterhouses by suggesting some of effective implementation ways. An awareness level survey using questionnaire for 124 owners and 363 employees of the slaughterhouses, and 170 government officers responsible for HACCP duties was performed. This study shows that only 34.7% of owners, 21.1% of employees, and 57.1% of government officers have good understanding of HACCP, but 93.5%, 88.9% and 93.6% respectively have the willingness of HACCP implementation. Major benefits in HACCP implementation in the slaughterhouse raised by respondents were improvement of hygiene level of the plant (54.1%), increase of meat sale (17.6%), pride of the production of safe meat for human consumption (9.6%) and increase of meat export (7.5%), while major obstacles were financial difficulties (33.2%), poor levels of the facilities and equipments in the plants (27.3%), poor level of personal hygiene (19.4%), and lack of understanding of HACCP (12.3%). The most urgent measures which respondents raised to implement HACCP system effectively in the slaughterhouses at the moment were the Improvement of levels of facilities and equipments in the plants (36.6%), the establishment of HACCP base through education and training (19%), special benefits to HACCP implementing plant (11.8%), and close relationship between government and the industry (10.3%). The present study shows some of effective ways to implement HACCP in slaughterhouses.

Predictive mathematical models were developed for predicting the kinetics of growth of Listeria monocytogenes in smoked salmon, which is the popular ready-to-eat foods in the world, as a function of temperature (4, 10, 20 and $30^{\circ}C$). At these storage temperature, the primary growth curve fit well ($r^2$=0.989~0.996) to a Gompertz equation to obtain specific growth rate (SGR) and lag time (LT). The Polynomial model for natural logarithm transformation of the SGR and LT as a function of temperature was obtained by nonlinear regression (Prism, version 4.0, GraphPad Software). Results indicate L. monocytogenes growth was affected by temperature mainly, and SGR model equation is $365.3-31.94^*Temperature+0.6661^*Temperature^{\wedge^2}$ and LT model equation is $0.1162-0.01674^*Temperature+0.0009303^*Temperature{\wedge^2}$. As storage temperature decreased $30^{\circ}C$ to $4^{\circ}C$, SGR decreased and LT increased respectively. Polynomial model was identified as appropriate secondary model for SGR and LT on the basis of most statistical indices such as bias factor (1.01 by SGR, 1.55 by LT) and accuracy factor (1.03 by SGR, 1.58 by LT).

This paper introduces a new type of industrial cluster developed at the CBD of Seoul. Conventionally, clusters are said to be consisted of hi-tech, often If activities, manufacturing industries or artisan craft industries with increasing vertical integration and performance usually supported by venture capitals and favorable business infrastructure, not to mention governments', be it central or local, incentive plans. The study area, Cheonggyechon region has long been a traditional CBD frame of Seoul, Korea, being troubled by deterioration, traffic jams, and environmental degradation as most inner cities experience. Recently. this region has transformed to the most dynamic and productive area not by IT industries but by apparel and fashion activities. The study of the developmental trajectory and key characteristics for this kind of industrial cluster can give us insight both for the transition of inner city and for the cluster theory. This Paper firstly briefly Profiles the growth of the Cheonggyechon region over the past decade. It then shows the current spatial and business structure of the new industrial cluster, focusing on the fact that transactions costs are reduced, the creation and flow of information improves. and the local institutions are prone to be most responsive to the new cluster's specialized needs. The third section presents the key components of the customized production-distribution-shopping cluster development process, emphasizing the localized networking. social capital, spontaneous institutionalization of associational economic climate, and cultural economy based on place-specific inertia. The paper concludes with some comments about the prospects and perils of the new industrial cluster of Seoul.

This study aims to develop and apply a standard management self-diagnostic table for forestry households to better manage their astringent persimmon production. The diagnostic table consisted of 3 categories (general status of a forestry household, management performance indicators, level of management) and 18 subcategories. The current management status across 241 households was surveyed among 10 chief astringent persimmon producing municipalities. Scores from the 18 subcategories were aggregated for a total score to evaluate and compare different levels of management. The respondents scored an overall average of 57.4, 62% of which were placed between 40 and 60. Upon close examination Chungcheongnam-do scored a very low score in the 'management system-tree height' subcategory with respect to the average score potentially because of the large population of aged trees in the region. The national average in the 'production skills-time of fruit load adjustment' subcategory was only 1.96 because unlike sweet persimmons astringent persimmons adjust their own load by inducing physiological fruit drop. The national average in the 'management/sales skills-material purchase' subcategory was 2.01; over 60% of the respondents indicated a preference for independent selection and purchase for most materials. The households preferring a group purchase tended to utilize the regional co-op.

The definition of edible ice is frozen water for the use of food manufacturing, processing, or cooking, as well as for the direct eating. It has been reported that in the process of ice manufacturing and its selling, edible ice is contaminated with some microorganisms, which causes food poisoning and gastroenteritis. It was shown that besides in the edible ice, germ growth caused by various reasons occurred in the mineral water, tap water, water filtering system, and water purifier. With public awareness, in order to examine the sanitary conditions of edible ice in the Northern area of Daegu metropolitan city, 15 places were randomly selected. As a result, 14 places were found to be contaminated with microorganisms. After incubating on the Brain Heart Infusion (BHI) agar plate, 80% of Gram-negative bacilli, 17% of Gram-positive cocci, and 3% of Gram-negative cocci were cultured. Enterobacter cloacae, Chryseomonas luteola, Pantoea spp., Klebsiella pneumoniae, Acinetobacter baumannii, Acinetobacter calcoaceticus or Providencia rettgeri were detected. Gram-positive cocci cultured in BHI agar plate from 5 specimens were identified as Staphylococcus aureus or Staphylococcus xylosus, which is well known bacteria causing strong food poisoning. This present paper raises questions on the importance and awareness of sanitary conditions of edible ice and the identification of pathogenic microorganisms living in the edible ice in relation to their distribution. The examination of sanitary conditions of edible ice in other areas in Daegu seems to be also needed to find out if there are similar cases.
