This study aims to examine the relation between opinion perception and opinion expression by issue types by analyzing online poll results and respective bulletin boards. To find out how opinion poll results affect the public opinion perception cues and opinion expression through the internet, the study applied a method of content analysis to the online contents provided by Naver.com, one of the most popular portal sites in Korea. A total of four issue types, along with 2,250 messages were chosen for analysis. The study results revealed that internet users perceived opinion atmosphere through the poll results and expressed their opinions depending on the issue types. In case of an issue where majority views are manifested as online poll results, users tended to follow that majority views by retaining their initial opinion. Majority opinion by the poll results held a dominant position in bulletin board. The results partially support Noelle-Neuman(1994)'s spiral of silence theory in the context of computer-mediated communication contrary to the belief that anonymity in the cyberspace tends to encourage participation of minority opinion group. According to the findings, people when they perceive their opinion as that of minority are discouraged to express their views even when they are online.

This reach is to comprehend the trend of father-related studies in Korea. The result of analyzing 161 father related thesis published from first issue until 2015.12 issue on 9 journals came out as below. First, father-thesis have increased. But the proportion of it remains for only 1~2% out of total 9 academic journals. Also the increased amount is very small considering the increasing rate of mother-thesis. In other words, the increased number of father-thesis is due to increased number of total amount of academic journals, which cannot be interpreted as the academic interest about fathering has grown. Second, almost of father-thesis were the empirical research and quantitative approach took the most part. Also father-thesis focus on 'what father's role is' and 'how much he does it'. Due to generalization of double-income family and an increase of interest about fathering, operational definition and a measurement issue is growing. Third, the topic of research which handles influence of father to child ranges from social relationship to social and emotional development. Also an interest of awarness development is growing. Meanwhile, research of father's influence to child development depends on cross-sectional data. Only few used vertical material.

This study investigates the impact of fiscal transfer, specifically the Village Fund Transfer, on rural income inequality and rural poverty. Studies on fiscal transfer offers contrasting outcomes, some argues that fiscal transfer suppresses wealth disparity, while others argue that it tends to widen disparity. This study employs descriptive analysis in estimating the elasticity of income inequality and poverty rate before and after the Village Fund Transfer. It develops multiple regressions model on panel datasets of 33 provinces in Indonesia before and after the implementation of Village Fund Transfer. This study suggests that the elasticity of income inequality is higher after the implementation of village fund transfer. Rural poverty tends to decline annually, however, the elasticity changes is lower after the implementation of village fund transfer. Furthermore, this study suggests that village fund transfer is insignificant in coping with the issue of income inequality, while education and the level of labor productivity of agricultural sector appears to be the determinant factor in tackling the issue of income inequality in the rural areas. This study further reveals the significance of village fund transfer in suppressing the rural poverty rate. This study also highlights the significance of human resources quality and agricultural sector in reducing poverty rate in rural areas.

This paper describes the packet traffic management of the Ubiquitous Healthcare System. In this system, ECG signal and accelerometer signal is transmitted from a wearable health shirt (WHS) to the base station. However, with the increment of users in this system, traffic over-load issue occurs. The main aim of this paper is to reduce the traffic over-load issue between sensor nodes by only transmitting the required signals to the base station when irregular activities are observed. In order to achieve this, in-network processing is adapted where the process of observation is conducted inside the sensor node of WHS. Results shows that irregular activities such as fall can be detected on real-time inside the sensor node and thus resolves traffic over-load issue.

API call sequence analysis is a kind of analysis using API call information extracted in target program. Compared to other techniques, this is advantageous as it can characterize the behavior of the target. However, existing API call sequence analysis has an issue of identifying same characteristics to different function during the analysis. To resolve the identification issue and improve performance of analysis, this study includes the method of API abstraction technique in addition to existing analysis. From there on, similarity between target programs is computed and clustered into similar types by applying LSH to abstracted API call sequence from analyzed target. Thus, this study can attribute in improving the accuracy of the malware analysis based on discovered information on the types of malware identified.

Vehicle rollover is an important issue for the traffic safety. Rollover can occur from the driver's action, the vehicle characteristics, or the road condition. This study is about the rollover propensity analysis of a jeep vehicle using the steering and braking maneuver, which is the combined result by the driver and the vehicle. Simple equations of roll motion is used to analyze the roll motion and a special purpose vehicle dynamics program is used to simulate the rollover of the jeep vehicle. From the simulation, an incipient rollover motion of the vehicle was found. However, the more complete rollover propensity analysis would require further investigation using roll dynamic sensitivity study.

The fashion industry is accountable for labor and environment-related issues. With such issues raised, consumers' social responsibility for environmental and labor issues has become an important factor that shapes the perception of companies. This study investigates the relationship between consumer values, concerns regarding social issues, and willingness to pay a premium for ethical fashion products. This study included two exogenous variables of altruistic value and egocentric value. In the conceptual model, consumers' social responsibility was conceptualized as two constructs of environmental consciousness and labor-issue consciousness. It was then analyzed as mediating variables. Willingness to pay a premium for ethical fashion products was the endogenous variable. Data was collected and analyzed with PLS-SEM from 600 consumers. The assessment of discriminant validity and construct validity using CFA were conducted before analyzing the model. Structural equation modeling results revealed that altruistic value directly influenced environmental consciousness and labor-issue consciousness. However, egocentric value was directly and significantly influenced only by labor-issue consciousness. Both environmental and labor issue consciousness directly influenced customers' willingness to pay a premium, but did not significantly change their willingness to pay a premium. Two-stage serial mediation analysis results indicated that the constructs did not have a significant mediation effect on the exogenous variables (altruistic value and egocentric value) and the endogenous variable (willingness to pay a premium) for ethical fashion products. This study found the influence of consumer's personal values on their willingness to pay a higher price for ethical fashion products.

We easily witness that environmental issue is very critical point to affluence upon a restructuring the value system of human being. Therefore it is obvious that this issue affluence upon the field of design as well. The most important feature of environmental issue is 'wholeness' in itself. It means that we have to approach and to solve it as a whole. Also, design is to be done at the same way. The creative professionalism of design could provide a clue to solve the problem, but designer are tend to seek a solution in a just partial way such as recycling and packaging. But those attitude may cause more problems and spread it futhermore. Therefore this study is analysis some recognitive turning factors in order to solve the problems as a whole, and to suggest a appropriate methods according to such a view point. Even internal retrospect in design itself or external demand from the other, If we look away this issue, the real purpose of design, contributing for society, should be diluted by ourselves.
