This study examines the perceptions on work-family balance and compares the differences of diverse groups in Korea. The success of work-family policies depends on employees' perceptions of both the tangible and intangible aspects of work-family supportiveness. A survey was conducted to produce a instrument that could measure the perceptions of work-family balance. The survey is a conducted random sample, with random selection of respondents who are working and over the age of 25 in Seoul and the metropolitan area. The research design employed ANOVA to compare the perceptions on work-family policies for supporting work-life balance in society. There was a difference in spillover levels between workers in different groups such as gender, employment status, age, the number of children, family type by employment status, company size, and industry. The findings will inform policy-makers as they continue to develop policies that positively affect working people.

This study testes an application possibility of the Elaboration Likelihood Model broadly used in communication science into forest science and examines the communication effects according to the media types. To examine the effectiveness of this model, the study sets involvement, the need for cognition, and the need for effect as motivation variable and prior knowledge as an ability variable. Most variables appear to be significant in the regression analysis and results of the study verify the possibility of the application of the Elaboration Likelihood Model in forest science. To measure the media effects, a simulation is also carried out using three media including television, newspaper, and the Internet. According to ANOVA analysis, television is more persuasive than newspaper, and there is no difference between television and the Internet in terms of persuasiveness. Regarding recall, television and the Internet are more effective than newspaper. Finally, the present study suggests effective and efficient forest communication policies based on the results.

The present research aimed at researching the relationships among place attachment, residential evaluations and satisfaction in a medium-sized post-communist Romanian city. Studies on post-communist cities are scarce and this research tried to fill that gap. This research is part of a government project that intended to significantly reform three medium-sized cities in the Western part of Romania and transform the urban space. Since the three of them are relatively small-sized and close spatially, the project intends to undertake massive reforms of the communications and services of the three cities. In this article, we report findings on the city of Hunedoara. A representative random sample was selected, and a total of 384 people were interviewed, with an overall reliability of the sample of 95%. The instruments used to gather the data were the Neighbourhood Perceived Environmental Quality Scale and a composite measure of place attachment was also included. The structure of each scale was checked using exploratory factor analysis. We tested alternative causal models using structural equations modelling. Our model showed a good fit to the data and explains satisfaction in the city adequately. Results show that satisfaction is directly predicted by the general evaluation of the city and by residential privacy. Residential noise and place attachment influence satisfaction indirectly. The results are discussed and some policy recommendations are formulated.

Despite the deep concerns against the DPRK and the harsh sanctions imposed on it, the country renders the sanctions futile by facilitating various illegal trades such as the ship-to-ship transfers of petroleum or coal. Recently, the international community went into paying attention to solve this matter. Among the measures the community can take, "reinforcing the search and inspection of the DPRK related vessels transiting in the high and territorial seas" is the best policy approach to reduce the sanction evasion and provide the international community with considerable bargaining advantages. This measure requires the forceful action by legal enforcement agencies, also known as VBSS. (Visit, Board, Search, and Seizure) It would make the deals prohibited by the UNSCRs (United Nation Security Council Resolutions) less profitable by reducing the expected return on the deals and increasing the cost for them. So, it would make the illegal deals under the table less attractive. The DPRK has been able to render the sanctions futile by exploiting the limitations of the current maritime sanctions. The resolutions are short of being specific about law enforcement, and the PSI (Proliferation Security Initiative) is legally nonbinding. However, if the UNSCRs and the PSI are combined, they can generate a new source of power and exploit the weakness of the DPRK. Noting that the recent UNSCRs stipulated all the legal discussions in the resolutions are confined and applied only to the DPRK, the PSI can target the commercial trade as well as the WMD-related materials in the case of the DPRK's illegal maritime practices. Therefore, the PSI endorsing partners should go beyond mere commitments. They should discuss action plans to implement the maritime interdictions to the extent that they discourage the DPRK and its business partners continuing the illegal activities.

Seaports are not longer considered to be single entities for which the main activity is to load and discharge cargo, but rather as fundamental hubs within a complex supply chain serving global production networks. From a public perspective, they hold a key role in terms of their economic impact at the local, regional and national level by generating value added activity and employment. This issue is becoming increasingly pivotal for ports and their stakeholders. The objective of the study is to estimate a regression model of the value added activity and employment figures of 17 Italian ports for which there are no publications available. Concerning port system reform in Italy, the research intends to provide policy makers with a tool to measure the effects produced by ports and their importance to local communities and regions. The paper finds that in all Italian ports, the direct effects are larger than the indirect effects, and the bigger socio-economic effects are found in the biggest ports.

Sentiment analysis is the review of written or verbal communications to determine some measure of emotion or feeling in the communication. Search engines are one of the most popular sites visited on the Internet generating hundreds of billions of hits per month worldwide. Obviously privacy policies related to these search sites are extremely important. Our study reviews the privacy policies of the two largest search engines, Google and Baidu to determine the overall sentiment of their privacy policies. Significant individual findings and significant differences were found using several sentiment and opinion analysis methods.

This paper attempts to re-evaluate the size of housing wealth effect in Korea. Our focus is on the size of 'genuine' housing wealth effect, i.e., the response of consumption spending by home-owners to the changes in housing wealth. Two issues show up while we estimate the 'genuine' wealth effects using aggregate time series data: the issues around home ownership and proper measure of consumption. We first argue that it is more appropriate to use non-housing consumption, because housing consumption is in large part not of the choice of home owners but the imputed rents they do not actually choose to pay. We then proceed to address the issue of home ownership, by examining how much to revise the estimates of housing wealth effect obtained from aggregate non-housing consumption data. We construct two structural models and estimate the share of home-owners' consumption in those models' context. It is found that, if properly revised in light of the estimated consumption shares of home-owners, the magnitude of resulting housing wealth effects are larger than what simple time series regressions imply.

In this paper, we studied how the data obesity can affect in which the response speed of database gradually slows down. Our research is performed by analyzing how the game data infrastructure is well-formed. Although there are a variety of ways to evaluate to measure the level of infrastructure, we performed with real information system. We analyzed data obesity by comparing the entity-relationship models between the products of real game information system and newly modeled databases. We could find data obesity is over 60% among overall average of game information system. It shows that 45% higher than standard obesity which is 15%. In this paper, data redundancy rate after performing the procedure of the data modeling was 41% resulting in an improvement of 23% compared to 64% of an existing model.

U-WHS refers to a means of remote health monitoring service to combine fitness with wellbing. U-WHS is a system which can measure and manage biometric information of patients without any limitation on time and space. In this paper, we performed in order to look into the influence that the encryption module influences on the communication evaluation in the biometric information transmission gone to the smart mobile device and Hospital Information System.In the case of the U-WHS model, the client used the Objective-c programming language for software development of iOS Xcode environment and SEED and HIGHT encryption module was applied. In the case of HIS, the MySQL which is the Websocket API of the HTML5 and relational database management system for the client and inter-server communication was applied. Therefore, in WIFI communication environment, by using wireshark, data transfer rate of the biometric information, delay and loss rate was checked for the evaluation.

This study aimed to understand the effects on preventive behavior intention to particulate matter by risk perception attitude and anxiety. Also, to expand applicable target and range of RPA model, add anxiety. To measure main variables of RPA model, did a survey with 570 college students. With a data, analyzed by correlation, one-way ANOVA and three-way ANOVA. As a result, perceived risk and efficacy effect on intention to preventive action and information seeking. And an anxiety factor effects on intention to preventive action and information seeking also. And distinguished 4 groups of RPA model, there were meaningful differences between intention to preventive action and information seeking by groups, and a factor of anxiety effects certain groups. As a result, it can suggest how to plan and enforce message on preventive campaign of particulate matter. In follow research, with social psychological factors, it will helpful to identify health activities about particulate matters.
