The operating system update is a basic step to maintain a safe internet use environment. This study analyzed whether the implementation of the operating system update was related to gender and age group during the violation accident prevention act in relation to information protection on the internet, and tried to verify the validity of these factors by analyzing the influence of gender and age group. In this study, logistic regression analysis was conducted based on the information security survey data surveyed by the Korea Internet & Security Agency in 2016. As a result, gender and age were surveyed as factors related to the implementation of operating system updates. As a result of analyzing the impact on the implementation of operating system updates by gender, it is estimated that the odds are 0.419 times higher for women than for men. According to the analysis of the operating system update by age group based on the 50s, which is a vulnerable group of information, the result is that the odds are 13.266 times higher in the 20s than the 50s.

In this study, we have examined the effect of open innovation of SMEs on innovation performance of firms. Most studies do not consider internal generation in relation to open innovation and innovation performance.We conducted empirical studies to overcome this problem. The research was carried out by collecting data collected from 512 SMEs and the 3SLS method was used to minimize the internal generation. As a result, open innovation investment and use of external ideas among SMEs' open innovation have positively influenced project success and technical performance. But, the introduction of technology and cooperation with the research organization did not affect the innovation performance, which is presumed to be due to the fact that the open innovation of SMEs is limited to relatively inexpensive activities. Therefore, in order to promote open innovation of SMEs, it is necessary to provide support for relatively high-cost activities and to improve the innovation performance of enterprises. In order to reduce the difficulties of open innovation activities, domestic universities and research institutes should support the construction of enterprise networks and actively support the utilization of technology to expand innovation performance.

This study explored users' emotional states identified from the wake-up words -"Hi, KIA!"- using a machine learning algorithm considering the user interface of passenger cars' voice. We targeted four emotional states, namely, excited, angry, desperate, and neutral, and created a total of 12 emotional scenarios in the context of car driving. Nine college students participated and recorded sentences as guided in the visualized scenario. The wake-up words were extracted from whole sentences, resulting in two data sets. We used the soundgen package and svmRadial method of caret package in open source-based R code to collect acoustic features of the recorded voices and performed machine learning-based analysis to determine the predictability of the modeled algorithm. We compared the accuracy of wake-up words (60.19%: 22%~81%) with that of whole sentences (41.51%) for all nine participants in relation to the four emotional categories. Accuracy and sensitivity performance of individual differences were noticeable, while the selected features were relatively constant. This study provides empirical evidence regarding the potential application of the wake-up words in the practice of emotion-driven user experience in communication between users and the artificial intelligence system.

The discussion of "new risks" in the field of social policy started to gain attention in the late 1990s and it is commonly argued that new risks are provoked by deindustrialization and/or globalization being more concentrated among the young, women and low skilled individuals. This study commences its inquiry with a conceptualization of labour market risk in an attempt to critically rethink the argument of new risk. A reevaluation of the concept is followed by an empirical investigation on the different types of risks and their changes by different degree. Eight-teen countries are selected in order to provide a comparative account to understand new risk. These are comparatively analyzed using the fuzzy-set ideal type approach to discover different types of social risks and to measure degrees of changes in relation to social risk. In sum, this paper aims to answer: what is new risk? and how do the characteristic of labour market risks differ in different post-industrial countries? The findings suggest that the types of risk are diverse and the speed or the directions of shift are also diverse.

The purpose of this paper is to examine the determinants of public attitudes toward welfare spending in relation with the perception of welfare level. Data from the national survey of 'the SSK Good Government Research Unit' are used to perform a logistic regression analysis of the association between welfare attitudes and government perceptions, political orientations, and socio-economic backgrounds. The most prominent finding is that the determinants of welfare attitudes differ markedly between the two different groups of welfare perception. The empirical results say that persons living in a corrupt government tend to prefer welfare spendings despite having low level of welfare, and persons living in a unjust government tend to prefer welfare expansion because welfare level must be low. Persons living in a government of great capacity tend to have positive attitudes to welfare spending despite having a high level of welfare, whereas persons living in a government of less capacity tend to have negative attitudes to welfare expansion because the level of welfare is too high beyond government capacity. This distinction between the two perceptions of welfare level provides a systemic understanding of public attitudes toward welfare spending.

This study aims to find out predictors of a movie's eventual box office, focusing on a movie's box office rank on an opening day. For an empirical analysis, I use data of 794 commercial movies released in the Korean theatrical exhibition market during the recent five years(2013~2017). The regression analysis shows that being box office number one on an opening day has statistically significant impact on a movie's final box office. A movie's quality, measured by audience's review, does not give significant impact on top1 movie's final success. Indexes such as increase of showing number on Sunday are strongly related to a movie's economic success. The additional analysis on box office number one movie on an opening day, totally 158 movies, finds that box office growth rate on a second week is strongly related to a movie's final success. Lastly, correlation coefficient of a movie's opening day box office and final box office does not show consistent growth when the coefficient is compared yearly. This study might have meaning in that it proposes new box office predictors and shows the relation of the indexes and a movie's final performance empirically.

This study measured the signal intensity (SI) of the hippocampus in relation to memory via fMRI analysis of 3 types of radiology symbols, 3 types of nuclear medicine symbols, and 3 types of oncology symbols among the most commonly employed medical symbols in hospitals. The following are the conclusions of the study. result of analyzing the SI values for symbol 1, symbol 2, and symbol 3 of the radiology, nuclear medicine, and oncology departments, symbol 3 had the highest SI value (1.72 ± 0.56) in radiology, symbol 2 had the highest SI value (1.69 ± 0.64) in nuclear medicine, and symbol 2 had the highest SI value (1.64 ± 0.63) in oncology. The overall mean of radiology, nuclear medicine, and oncology symbols was 1.62 ± 0.60 for nuclear medicine, 1.61 ± 0.59 for oncology, and 1.49 ± 0.49 for radiology. According to the overall SI measurement results, symbol 3 in radiology, symbol 2 in nuclear medicine, and symbol 2 in oncology were confirmed to have high SI values. If symbols with high SI values are used in a hospital, it is believed to be beneficial for navigating in any hospital.
