  • Background : This study was conducted to determine out the effect of storage temperature on the quality of fresh ginseng (Panax ginseng C. A. Meyer) during distribution. Methods and Results : Fresh ginseng was washed, packed in $30{\mu}m$ low density polyethylene (LDPE) film, then stored at 0, -2 and $-4^{\circ}C$. After 4 weeks of storage, ginseng was then stored at $5^{\circ}C$, as a simulation of the distribution process. Ginseng stored at $-4^{\circ}C$ showed higher respiration rate, ethylene production and electrolyte conductivity during the distribution phase than those stored at 0 and $-2^{\circ}C$. Decay and browning rate rapidly increased following 3 weeks of distribution in samples stored $-4^{\circ}C$. However ginseng stored $-2^{\circ}C$, which is below freezing point, for 4 weeks did not show the physiological change or quality deterioration. Ginsenoside contents decreased during storage for all plant, but did not differ significantly between storage temperatures. Conclusions : Storage at temperatures below $-2^{\circ}C$ can negatively affect respiratory characteristics and electrolyte leakage and increase quality deterioration and decay rates during distribution.

  • The quality characteristics were measured, using sensory evaluation and mechanical characteristics, for the addition of different percentages of apricot juice(0%, 5%, 10%, 15%, 20%) to rice flour, in order to promote the use of and liking for the traditional Korean rice cakes. The pH was decreased with apricot juice addition, while acid was increased. The moisture contents were 36.2${\sim}$45.0% . The L-value was decreased with increasing apricot juice addition, while a- and b-values were increased. In mechanical texture characteristics, hardness, gumminess and brittleness were the highest at the 10% apricot juice level(p<.001). Springiness was also the highest at 10% level but the difference was not significant. In the sensory evaluation, the color, flavor, sourness, hardness and chewiness were increased with apricot juice addition. Apricot sulgidduk made with the addition of 10% apricot juice to rice flour was found to be the best recipe in terms of acceptability, flavor quality, taste quality, and overall quality and there was a significant difference between the samples. The springiness was negatively correlated with the cohesiveness, springiness, gumminess and brittleness while moistness was positively correlated with moisture, hardness, cohesiveness, springiness, gumminess and brittleness.

  • The objective of this study was to investigate the effectiveness of preservatives for extending storage life and maintaining the quality of minimally processed Chinese cabbage. Cut Chinese cabbage was treated with either 1% CaCl2, 1% NaCl, 3% sucrose, 1% Ca-lactate, 1% vitamin C, 0.05% chitosan+1% vitamin C, 0.1% Sporix+1% vitamin C or hot water(6$0^{\circ}C$) and then packed with polyethylene film(60${\mu}{\textrm}{m}$) and stored at either 2$0^{\circ}C$ or 4$^{\circ}C$. To evaluate biochemical changes and quality of minimally processed Chinese cabbage, the samples were tested to determine the amount of vitamen C, titratable acidity, organic acid and fiber contents. Changes in color were also examined. The quality of kimchi prepared form minimally processed cabbage was affected by the treatments. REsults indicate that the minimally processed Chinese cabbage treated with either 1% CaCl2 at 2$0^{\circ}C$ and 4$^{\circ}C$ or 1% NaCl at 2$0^{\circ}C$ minimized biochemical changes in plant tissue and those treatments were most effective in maintaining product quality. The cabbage treated with 1% vitamin C or 1% NaCl at 4$^{\circ}C$ resulted in kimchi with improved color, texture, flavor and the best overall acceptability, as determined by a sensory test.

  • The purpose of this study supports the establishment of national e-learning policy by analyzing e-learning status and current status of higher education. Enhance the competitiveness of higher education through sharing information between universities. And to improve e-learning quality management. We surveyed the current status of e-learning in 341 universities and questionnaires about e-learning content, e-learning application form, e-learning platform status was surveyed through each school's learning management system. As a result, the infrastructure of e-learning, the rate of platforms secured, and the contents are increasing gradually each year; however, still, not all students can receive the services equally. Dedicated servers and learning management systems were secured by more than 70% of general universities. In the current development status of e-learning content, multimedia, animation, and text forms are gradually decreasing, but video contents are increasing every year. Most of the online contents were used in the e-learning contents by application type, and blended learning, flipped learning, and mooc is not yet actively used since they are still in the beginning stage. Learning analysis techniques should be supported in order to easily use online learning contents such as flipped learning and mooc. We suggest that the effectiveness of e-learning should be measured and the current state of learning analysis for customized learning should be done. This study aims to contribute to the improvement of competitiveness of higher education by sharing information about e-learning among universities as a basis for improvement of e-learning policy. Future tasks are to improve the customized learning environment by adding whether the system environment for learning analysis is provided at the time of the survey.

  • CT(computed tomography, CT) examinations is one of the most useful diagnostic equipment for identifying information in the human body in diagnostic radiology. Recently, the number of CT scans is increasing every year due to the high reliability of CT scans. Increasing the number of tests will accelerate the aging of CT devices, which is why the importance of quality management for CT devices is on the rise. Particularly in CT, quality management refers to a behavior of figuring out and correcting all sorts of hindrance factors that can cause all the problems related to the equipment associated with the diminishment of diagnosed area due to the reduction of image quality in clinical imaging in advance and maintaining a consistent level of image quality and obtaining a proper image. Here, these researchers aim to summarize and report the general contents of quality management in CT.

Method: The review contents of the 165 papers were selected 217 papers that were submitted in 2003. Among those 165 papers, the 21 papers belonged to the 'Do not publish' list and 17 papers, 'Revise manuscript and resubmit', list and the 94 papers, 'Publish if revisions are made' list. There are more than two level differences among the four levels of decision in acceptance of publication in 33 papers. Results: The analysis of the review contents for the papers were suggested according to review categories: introduction, method, results, discussion and conclusion. In addition, if papers had more than two levels of review they were rated poor accord or inconsistent. Conclusion: For the quality of the academic journal and development of the nursing science, it is important to disseminate and publish the research paper. Therefore, review of the submitted paper is also important. Implications for the profitable review were suggested in the study.

  • The purpose of this study was to provide data for development of child-care programs. For this purpose, mothers' demands were investigated. The subjects included 403 mothers with children enrolled in child-care centers located in Yangju city, Gyeonggi-do. The data were analyzed by frequency, percentage, cross tabs, t-test, and F-test. The major findings of this study were as follows: First, satisfaction with child-care centers was positive. Second, the major reasons for dissatisfaction with child-care centers came from facilities and program contents of inferior quality. Third, mothers emphasized the importance of teachers' role and social-emotional development as quality criteria for child-care programs. There were differences in mothers' demands according to their demographic characteristics.

  • Squid Sikhae is traditional salt-fermented food in Korea. We evaluated the standardization of optimal processing conditions for desirable quality-controlled squid Sikhae using analyses of physiochemical properties, microbiological species, and organoleptic tests. Among several squid Sikhae preparation processes, the optimal fermentation temperature sun-dried sea salt concentration, and fermentation period for squid Sikhae of acceptable quality were $10^{\circ}C$, 4%, and 6 days, respectively. Amino-N and volatile basic nitrogen (VBN) contents of the acceptable quality squid Sikhae were 162.51 mg/100 g and 15.25 mg/100 g, respectively.
