Optimal processing conditions and shelf-life of steamed kamaboko made from Alaska pollock surimi were investigated, including protein digestibility, computed protein efficiency ratio (C-PER), trypsin inhibitor content and protein solubility. Steamed kamaboko containing $5\%$ starch and $33\%$ water in pollock surimi showed the best protein quality in terms of C-PER and protein digestibility. Steaming could not give any significant advantage over kamaboko protein digestibility but a higher C-PER resulted from steamed kamaboko. All kamaboko products had trypsin content of 1.4 to $2.0mg\%$ which was $10\%$ of total trypsin inhibitor levels in frozen pollock meat. A two stage steaming process, the first at $40^{\circ}C$ for 20min followed by a second 10min steaming period at $95^{\circ}C$, was found to be the most effective way of the most effective heating process for kamaboko protein quality. C-PERs of marketed Korean surimi products ranged from $2.8{\sim}2.9$ for steamed kamaboko and $2.9{\sim}3.2$ for crab meat analog which were superior to ANRC casein(2.5). Measured protein digestibility of all products were ranged from 86 to $89\%$. VBN and protein solubility data suggest Korean marketed surimi products could have a shelf-life of 15 days at $4^{\circ}C$ for crab meat analog and 20 days at $4^{\circ}C$ for steamed kamaboko.

In this study, the food service management levels of cafeterias in childcare facilities were investigated based on the number of meal recipients and the working status of the kitchen staff. The study included 199 childcare facilities nationwide that received food supplies from the food ingredients distribution company, Pulmuone Foodmerce, from 2021 to 2022. The assessment was conducted using 61 inspection items. The analysis revealed that, as the number of meal recipients and kitchen staff members decreased, the documentation of inspection results was less likely to be conducted (P<0.05). Facilities with fewer meal recipients showed less adequate health status checks for kitchen staff, and those with fewer kitchen staff showed insufficient compliance with hygienic clothing (P<0.05). Additionally, facilities with fewer meal recipients showed a higher frequency of lapses in checking the expiration dates of stored ingredients (P<0.05), requiring increased management attention. They also exhibited the absence of internal temperature measurement records during heating processes (P<0.05). Furthermore, facilities with fewer meal recipients demonstrated inadequate maintenance of kitchen facilities (P<0.05). Significantly higher adenosine triphosphate (ATP) levels were detected on the hands and cutting boards of the kitchen staff in facilities with fewer meal recipients and fewer kitchen staff (P>0.05). Overall, facilities with fewer meal recipients exhibited insufficient infrastructure management for kitchen operations and inadequate hygiene management. These results are expected to provide foundational data for the selection of national support programs for childcare facilities in the future.

Recently, fake test data of power cables in nuclear power plants was a terrible shock to the citizens. Some cable companies manipulated the test data to make unfair profits. In addition, fake test data cases were found in military supplies. The fake test data cases focused on parts of army's tank, armored car. This paper propose a new method that can detect fake test data using known statistical methods. In addition, the method was implemented in Microsoft Excel to allow easy use. Lastly, a check sheet was proposed to check the validity of the test system of military suppliers. By detecting and checking the fake test data, it is expected that our new method will play an important role in quality assurance of military supplies.

Information system audit, by checking overall matters about constructing and managing information system, has to contribute to improvement of information system's quality and improving performance of projects. For this, an auditor has to present objective corroborative facts which back up result of audit and ways of improvement, but in reality, general(especially businessmen's) cognition is that audit is biased by way too subjective opinions. Local experience and theoretical research until now propose that tools of automating audit will be an active means of systematically collecting and proposing these objective evidences of audit. This research not only verified that in the field of audit, phenomenon of technology application can be explained and predicted by applying TAM, but it also contributed in extending theoretical base on information technology and audit by distinguishing several characteristics which appear in the process of the model's application and analysis.

Multi-trade Contract Method was introduced as a means of cutting down construction cost of public housing for low income people. Before a specific project delivery method is applied to large public construction project, it is necessary to discuss all the issues raised up from all the parties in construction industry and all the issues which can impact project performance. Thus the interviews were conducted with industrial professionals from diverse organizations and previous studies were investigated to figure out how this newly introduced project delivery method may impact owner's role and responsibility and project performance in terms of cost, schedule, quality and risk. Under the Multi-trade Contract Method, project owner's management tasks will be highly increased, so it should be checked out if the owner can do its role and responsibility. Public owner's organization also needs to be changed and proper project management procedure and system need to be established. In addition, for efficient application of Multi-trade Contract Method, public owner should consider diverse management approach to deliver the project, and how to select and maintain qualified specialty trades.
