  • In order to establish the processing condition of rapid- and low salt-fermented liquefaction of anchovy (Engrulis japonica), effect of temperature on crude enzyme activity of anchovy viscera, pretreatment conditions, and the minimum content of adding NaCl were investigated. The minimum limitation of NaCl content for anchovy liquefaction was 10%. Sample A(water adding, heating, adding 10% NaCl): chopped whole anchovy adding 20% water and then heating for 9 hrs at $50^{\circ}C$ and then adding 10% NaCl and then fermented at room temperature$(8-29^{\circ}C)$ for 180 days. Sample B(water adding, heating, adding 13% NaCl): chopped whole anchovy adding 20% water and then heating for 9 hrs at $50^{\circ}C$ and then adding 13% NaCl and then fermented at room temperature for 180 days. Sample C(adding 13% NaCl): chopped whole anchovy and then adding 13% NaCl and then fermented at room temperature for 180 days. Sample D(adding 17% NaCl): whole anchovy adding 17% NaCl and then fermented at room temperature for 180 days. The content of free amino acids such as aspartic acid, serine and threonine fluctuated severely according to the pretreatment methods. Possibly they might be recommend quality indices of standardization for salt-fermented liquefaction of anchovy. As for the relation between fermentation period(X) and individual free amino acid(Y), five kinds of free amino acids such as glutamic acid, valine, glycine, lysine, and alanine showed highly significant in their coefficient of determination in most of samples. They might be recommend as quality indices for salt-fermented liquefaction of anchovy during fermentation. The difference of taste between products of the rapid- and low salt-fermented liquefaction and the traditional salt-fermented liquefaction were caused by their composition of the free amino acids ratios, in which were umami, sweet, and bitter taste in the extracts of anchovy during fermentation. The appropriate fermentation period of the sample A was shorten 30 days than the sample B and 60 days than the samples C and 90 days than the sample D in the processing of anchovy.

  • Purpose - This study examines college students' perceived choice attributes in traditional markets and the relationship quality. We study the relationships between attributes that common people look for while choosing a store (e.g., product, service, advertising, and atmosphere), consumption emotion, consumer's value, and relationship quality. Research design, data, methodology - In order to verify the relationship between choice attributes and relationship quality, and moderating (i.e., consumption emotion) and mediating effects (i.e., customer value), we collected data from 202 consumers in Gyeonggi province to test the theoretical model and its hypotheses. For this purpose, this study, utilized an empirical methodology. Results - First, contrary to the previous research findings involving college students, this study observed that four factors of store choice attributes at a traditional market were important to consumers in heightening the relationship quality. Specifically, product (β = .608, p < .01), service (β = .351, p < .01), advertising (β = .237, p < .01), and atmosphere (β = .425, p < .01) are significantly related to relationship quality. Second, consumers selected product (β =. 521, p < .01) as the most important attribute. Atmosphere (β = .254, p < .01) and service division (β = .148, p < .05), in this order, are the other important factors in this regard. However, advertising (β = -.112, p = .100) is not statistically significant. To improve and develop the relationship quality with consumers, traditional markets should ensure supply of suitable products and goods, improve store atmosphere by modernizing facilities, and educate merchants to improve their services. Third, the results of the moderating effects, although marginally statistically significant, suggest that for the consumers with low consumption emotion for traditional markets, an affirmative experience of products and store atmosphere heightens their values. In addition, the consumers having low consumption emotion who could promote consumer values were found to improve and develop a marginally significant relationship quality. Finally, the study revealed that the consumer's value exhibited a complete mediation effect in the relationships between service and relationship quality, and advertising and relationship quality and a partial mediation effect in the relationships between product and relationship quality, and atmosphere and relationship quality. Conclusions - Consumer satisfaction is important to increase the competitiveness of traditional markets, and products and store atmosphere are important attributes to increase the relationship quality. Specifically, merchants should supply different products, modernize their facilities, and improve store atmosphere to compete in traditional markets. In addition, traditional markets should provide value and competitive prices to attract consumers, and should maximize the consumer's value and promote the consumption emotion. Traditional markets should evolve to accommodate changes in the consumer's value and invest in not only functional elements but also symbolic elements.

  • Squid (Todarodes pacificus) is processed as dried or seasoned-dried products and its catch gradually increased from 270,298 M/T in 2005 to 367,940 M/T in 2008 in Korea. Squid processing by-product (viscera) was usually discarded as a waste resulting in environmental problem. In order to utilize squid viscera for more value-added products, a natural squid seasoning was developed by fermenting with Aspergillus oryzae koji. Squid viscera at 5, 10 and 15% salt concentrations with fixed levels of 5% koji and 30% water was fermented at room temperature. The quality properties of squid fermented products such as amino-N, TMA, VBN, total viable cell count, pH and total acidity were determined at different fermentation periods. The contents of amino-N, TMA, and VBN of squid seasoning at 5% salt concentration fermented for 14 days were the highest. Based on amino-N content, squid viscera at 5% koji fermented for 14 days was selected for further assays: the content of moisture, crude protein, crude lipid, crude ash, and carbohydrate were 5.98, 35.19, 33.08, 11.30, and 14.45%, respectively. The content of glutamate, alanine, leusine and lysine were 7.06, 12.34, 9.90 and 10.22%, respectively. The $IC_{50}$ values of DPPH scavenging and $\beta$-glucuronidase inhibitory activity were 12.89 and 12.58 mg/mL, respectively. A natural squid seasoning was manufactured by mixing fermented squid viscera and an ingredient. Based on the results of sensory evaluation, the fermented squid viscera seasoning was almost equal to other natural complex seasonings such as anchovy, cow meat, and fisheries seasoning.

  • The objective of this study is to develop an analytic framework to code systematically the gamer's behaviour in MMO(Massively Multi-player Online) gameplay experience, to explore their gameplay as a problem solving procedure empirically. Previous studies about model human processor, content based protocol, and procedure based protocol are reviewed in order to build the outline of the analytic framework related to MMO gameplay. The specific gameplay actions and contents were derived by using concurrent protocol analysis method through the empirical experiment executed in MMORPG gameplay. Consequently, gameplay are divided into six actions : kinematics, perception, function, representation, simulation, and rule (heuristics, following, and transcedence). The analytic framework suitable for MMO gameplay was built. As a result of this study, we found three rule spaces in the problem solving domain of gameplay that are an heuristics, a following of the rule, and a transcendence of the rule. 'Heuristics' denotes the rule action that discovers the rule of game through trial-and-error. 'Following' indicates the rule action that follows the rule of game embedded in game by game designers. 'Transcendence' presents the rule action that transcends that. The new discovered rule spaces where 'Following' and 'Transcendence' actions occur and the gameplay pattern in them is provided with the key basis to determine the level design elements of MMO game, such as terrain feature, monster attribute, item, and skill et cetera. Therefore, this study is concludes with key implications to support game design to improve the quality of MMO game product.

  • Software development based on product lines has been proved a promising technology that can drastically reduce cycle time and guarantee quality by strategically reusing quality core assets that belong to an organization. However, how to measure within a product line is different from how to measure within a single software project in that we have to consider the aspects of both core assets and projects that utilize the assets. Moreover, the performance aspects of overall project lines need to be considered within a product line context. Therefore, a systematic approach to measure the performance of product lines is essential to have consistent, repeatable and effective measures within a product line. This paper presents a context-based measurements elicitation approach for product lines that reflects the performance characteristics of product lines and the diversity of their application. The approach includes both detailed procedures and work products resulting from implementation of the procedures, along with their templates. To show the utility of the approach, this paper presents the elicited measurements, especially for technical management practices among product line practices. This paper also illustrated a real application case that adopt this approach. The systematic approach enables management attributes, i.e., measurements to be identified when we construct product lines or develop software product based on the product lines. The measurements will be effective in that they are derived in consideration of the application context and interests of stakeholders.

  • The architectural drawing, construction project specification, etc. are included in the contract of a documents. However, construction project specification, for being documentation, is not utilized to such an extent. The reason is that specification information is difficult in collecting information in relation to the architectural drawing, material finishing list and other architectural information. Therefore, an integrated model, which can be associated with other architectural information, is needed, and a DB based on this integrated model must be established in order for it to be utilized in design, construction, and management. The DB, which is established through this process, must be updated according to modification in design, and construction. Furthermore the specification must be in document on the web for reference. Consequently in this research, the structure of integrated model has been introduced, and it has made the search and preparation of the integrated model on the Internet, using the specification information DB established for the mutual reference of DB, possible. The improvements of construction project specification standards are expected by this system. Also, it will bring about Improvements upon claim prevention, and design, construction, management qualities. Furthermore, it will make the use of information more convenient in practical business such as order agency, design service and building site.

  • It is desirable to use a monthly benchmarked construction indicator which contains the characteristics of statistical data in an annual survey in order to analyze the cyclical phenomenon of the construction activity. The benchmarked indicator is expected to improve the data quality in terms of accuracy, consistency, comparability, and completeness. In this paper, benchmarking methodologies of compiling monthly construction indicators arc researched by using a monthly prompt data holding short - term fluctuations and an annual survey data regarded as more accurate statistics than monthly data. The benchmarking is the methodology by which a high frequency data should he adjusted in order to hold the short-term and cyclical phenomena, and the long - term trend of two data groups with ensuring the consistency of an annual summation between a high frequency data and a low frequency data. This paper considered the numerical approach like pro rata distribution method, proportional Denton method, EFL or HP filter Benchmark - to - Indicator ratio method, and the model - based approach such as Chow and Lin method, $Fem{\acute{a}}ndez$ method. Also, the benchmarked construction indicators were estimated by early mentioned benchmarking methods with practical data, and these methods were empirically reviewed and compared. In case of construction indicators with severe seasonal fluctuations and irregulars, the numerical approach seemed to be performed more correctly than the model- based approach. Among numerical methods, the proportional Denton method used in general was a little nice. The HP filter Benchmark - to - Indicator ratio method may be considered with survey errors or measurement errors in an annual survey data.

  • The purposes of this study were to analyze the quality attributes, quality factors and customer satisfaction in school foodservice and to provide suggestions for improving school foodservice environments. The survey was distributed to different respondents (5,771 students, 2,045 parents, and 1,981 faculty members) at different types of schools (elementary school, middle school, and high school) on September 2010 in 16 cities and provinces. The data were analyzed using SPSS for descriptive analysis, one-way ANOVA, t-test and multiple linear regression analysis. First, all foodservice quality attributes were significant different by respondents and the faculty had higher scores than parents and students. A comparison of scores by respondents and distribution place demonstrated that classroom of student and parents had a higher score for quality attributes. The overall satisfaction with school foodservice was significant different by respondents and higher for classroom than for dining hall for student and parents. In comparison of annual data, there was decreased overall satisfaction and quality attributes in student and parents. Second, in the regression results, which showed the effects of the foodservice quality attributes on overall satisfaction by respondents and distribution place, improvements of 'food taste', 'pleasant foodservice environment', and 'kindness of employee' would increase satisfaction in most of the respondents. Third, the overall satisfaction with school foodservice was higher for nutrition teachers than dietitians for students and faculty. Therefore, the operators will need to make different efforts based on each customer needs to improve the overall satisfaction on school foodservice.
