This study is designed to analyze the effect of entrepreneurship orientation of owner managers on product innovation performance through user innovation participation by using Korea Innovation Survey 2014 (KIS 2014) conducted by STEPI (Science and Technology Policy Institute). The findings show that entrepreneurial orientation of owner managers measured by a proxy variable of ownership ratio has positive relationship with innovation performance of firms. They also present that user innovation activity has a partial mediating effect on the relationship between the entrepreneurial orientation of owner managers and innovation performance of firms. This study suggests that the higher the entrepreneurial orientation of the owner manager, the higher the innovation performance. The innovation performance can be intensified when the open innovation strategy is implemented through the user participation.

This study aimed to understand and analyze the learners' class satisfaction and the effectiveness of synchronous online classes after COVID-19. A total of 188 learners participated in the survey conducted at the end of the Fall Semester 2020 at C University located Gyeongsangnam-do. Findings revealed that learners' satisfaction with the synchronous online classes was relatively low, and the learners had negative perception of that. Learning content have the biggest effect on the learners' class satisfaction. Next came class management and the online learning platform. Therefore, instructors need to organize learning content effectively and enhance learners' understanding considering the most influential variable, learning content so that learners are satisfied with the synchronous online classes. Also, instructors should make it possible for learners to get familiar with the online learning platform and use it without any problems through systematic and faithful class design for effective learning in unfamiliar online learning environment. In addition, instructors need to know learners' needs and difficulties and plan their synchronous online classes. This study has limitations in that it was conducted only at one college and the limited number of variables was measured.

This study aimed to understand and analyze the instructors' class satisfaction and the effectiveness of online general education classes perceived by instructors after inevitable COVID-19. A total of 54 instructors participated in the survey conducted at the end of the spring semester 2021 at C University located Gyeongsangnam-do. Findings revealed that instructors' satisfaction with their online classes was relatively low(2.80), and they negatively perceived their online classes. Also they show negative perception of the variable, interaction with learners(2.87). However, they show higher satisfaction with the next variables than the overall satisfaction; class management, online learning platform, and asynchronous online learning. Plus, a statistically significant result is that online learning platform have the biggest effect on the instructors' class satisfaction. Therefore, we need to know that instructors have to get familiar with the online learning platform and universities help them provide a variety of training sessions regarding online learning platforms. This study has limitations in that it was conducted only at one college and the limited number of variables was measured.

The shape of the male beard to be examined in this study was set as a mustache. This study used frequency analysis and cross-tab analysis to conduct T-test and one-way variance analysis using 300 final responses from the questionnaire that presented preference and non-preference reasons and demographic characteristics along with preference and non-preference options to measure the likability of whiskers. As a result of the study, there were differences in men's preference and non-preference for each beard formulation, and the level of difference was statistically significant between the male and female groups and the age group. In addition, it was found that each group category showed a difference in the reasons for judging likes/dislikes by beard form. There are differences in preference and non-preference according to men's beard formations, and it was confirmed that there are various differences according to perceptual characteristics in the main reasons for favorability and dislike, which are the basis for judgment. Through these results, academic and practical implications were presented in the field of beauty.

The self-report assessment has been most commonly used to estimate bullying/victimization (B/V) rates in most domestic and international prevalence studies. However, the presence of many potential biasing factors in such an assessment method, including specific operationalization/measurement strategies and testing conditions, has become an issue due to a considerable variability in reported involvement rates across studies. This study analyzed self-reported B/V involvement rates on Olweus Bullying Questionnaire (OBQ) among 690 Korean middle school students by gender and two different cut-offs (generous vs. strict cut-offs) and examined if the involvement rates were significantly varied by testing conditions such as presentation vs. omission of a precise definition of B/V, anonymous vs. non-anonymous/confidential administration, and the use of global vs. specific questions. Chi-square analyses revealed that boys displayed higher involvement rates on global measures of B/V and on items related to direct forms of B/V, with no significant gender differences on specific measures of relational B/V rates. It was also found that a global rate of bullying and specific rates of verbal B/V were 111% to 157% higher when no definition was provided. However, anonymous vs. non-anonymous administration had no significant impacts on rates of involvement, except for one item; there were also no significant differences in reported degrees of frankness and perceived confidentiality of their responses across two adminstration conditions. Finally, when involvement rates were assessed by using specific vs. global items, they were 68% to 148% higher with binominal correlations in low to moderate ranges. Findings also indicated that global items had a high specificity but a relatively low sensitivity. Implications of these findings were fully discussed for researchers and practitioners in the field of B/V assessment.

In line with the entry into the digital-based intelligent information society, the science curriculum emphasizes the cultivation of scientific competencies, and computer-based test (CBT) is drawing attention for assessment of competencies. CBT has advantages to develop items that have high fidelity, and to establish a feedback system by accumulating results into the database. However, it is necessary to solve the problems of improving validity of assessment results, lowering measurement efficiency, and increasing management factors. To examine students' responses to the introduction of the new assessment tools in the process of transitioning from paper-based test (PBT) to CBT, in this study, we analyzed the results of the PBT and the CBT conducted in 2021 National Assessment of Educational Achievement (NAEA). In particular, we sought to find the effects on student achievement when only the mode of assessment was changed without change of items, and the effect on student achievement when the items were composed including technology enhanced features that take advantage of CBT. This study is derived through the analysis of the results of 7,137 third-grade middle school students taking one among the three kinds of assessments, which were the PBT or two kinds of CBT. After the assessment, the percentage of correct answers and the item discriminations were collected for each group, and expert opinions on characteristics of response were collected through the expert council involving 8 science teachers with experience in NAEA. According to the results, there was no significant difference between students' achievement results in the PBT and the CBT-M, which means simple mode conversion type of CBT, so it could be explained that the mode effect did not appear. However, it was confirmed that the percentage of correct answers for the construct response items was somewhat high in the CBT, and this result was analyzed to be related to the convenience of the response. On the other hand, there were the items with a difference of more than 10%p from the correct answer rate of similar items, among the items to which technology enhanced functions were applied following the introduction of CBT. According to the analysis of response rate of options, these results could be explained that the students' level of understanding could be more closely grasped through the innovative items developed through the technology enhanced function. Based on the results, we discussed some guidance to be considered when introducing CBT and developing items through CBT, and presented implications.

This study was performed to investigate effects of raw sea tangle products on idiopathic constipation. A total of thirty-eight women participated voluntarily in this study. They were placed into one of four groups by their total colonic transit time (TCTT) to make the four groups have the same TCTT. In the first trial, the subjects in Control group were fed 3 times of 150 mL of mineral water per day for 2 weeks, those in +Control group were fed a kind of stool softener as well as the same mineral water for 3 times, those in STT group were fed 3 times of 150 mL of sea tangle tea and those in STB group were fed 3 times of 150 mL of sea tangle beverage. After 6 weeks, a second trial was performed for another 2 weeks. Although the TCTT of the group exposed to of KolomarkTM was not significantly reduced, the subjects in STT group answered that their evacuation activities were significantly improved; evacuation frequency was increased, stool hardness was reduced, evacuation straining was lessened, stool amount was increased, incomplete sense of evacuation was lessened, and major evacuation time was improved like those in +Control group. The results imply that it is worthy to develop some products of raw sea tangle such as STT, which are effective in treating or preventing constipation.

In this study, we conducted a questionnaire survey for the purpose of finding a method of mobile sector ecosystem activation targeted at small and medium businesses (SMBs). Through the total of 204 responders consisting of business employees from each mobile sector, we analyzed the factors inhibiting the development of the mobile ecosystem and preventing the activation the mobile market, as well as conducting a diagnosis of the digital potential. This paper presented suggestions for searching for a systematic supporting strategy considering the short-term inhibitory factors (market structure improvement, financial support, etc.) and long-term orientation factors (personnel nurturing, strengthening of supporting role by governmental initiative) for the activation of the domestic mobile market. After measuring the digital potential, we found that domestic mobile SMBs have perceived the importance of the digital potential and have considered and readied themselves for the future market. The present survey found that if suitable digitalization can be accomplished for their firms' products and services, they have the ability and willingness to succeed in the market. However, they have a hard task ahead of them from adigital delivery perspective given the potential for digital disruptions.
