Trust is generally assumed to be an important precondition for people's adoption of e-government services. This study analyzes the direct and indirect impact of information privacy, interactivity, subjective norms and words-of-mouth on perceived trust of e-government services and trust toward government. The Partial Least Square(PLS) was applied to the citizen survey data for hypotheses testing. PLS permits the simultaneous testing of cause-effect hypotheses while also allowing evaluation of the measurement model. Statistical results indicate that interactivity, subjective norms and words-of-mouth positively affects perceived trust of e-government services, which in turn affects the level of political efficacy and the trust toward the government. Interactivity has been found to affect words-of-mouth as well. However, information privacy has no significant effect on the trust of e-government services.

A trial has been made to find out a new method of calculating the survival rate of a fish Population utilizing the length composition data and the characteristics of the frequency curve of the length which usually is normal distribution curve. In this paper, a stochastic method is introduced and applied to calculate the survival rate of yellow croaker caught by Korean trawlers in the Yellow Sea and the East China Sea in 1971. The results are as follows : Mean of survival rate 0.46089 Variance 0.03073 Standard deviation 0.17529 95 percent confidence interval 0.36040-0.56138.

남북의 상호이해, 신뢰회복, 이질감 완화를 위해 대내외적 정치적인 변수에 상관없이 남북방송교류는 지속되어야 한다. 이를 위해 기존의 사회문화적, 단발적인 남북방송교류를 비정치적인 분야인 방송기술협력을 기반으로 한 장기적이고 지속적인 프로젝트형 남북방송교류로 전환하는 하는 것이 필요하다. 본고는 평화공존과 협력이라는 방향성 아래 남북이 상생할 수 있는 효과적인 방송기술협력 방안을 모색하고자 한다.

There are many situations arising in reliability engineering and biomedical science where failure of a subsystem increases the failure rate of other subsystem under shared load models. In this paper, the maximum likelihood estimates and the modified maximum likelihood estimates of mean time to failure and reliability function for shared load model with guarantee time are obtained by using censored system life data. Some illustrative examples are included.

동북아시아지역에서 집단안보와 관련된 지역협력체가 형성되기 어려운 이유에는 먼저 체제와 이념이 다른 국가들 사이에서의 강한 지정학적 역학관계가 작동하고 있고, 두 번째로 개별국가 내부의 사회이념과 정치체제의 차이로 인한 이질성이 매우 강하며, 세 번째로 새롭게 형성되고 있는 미-중 관계의 대립적 구도가 군사안보적인 차원에서의 과도한 경쟁관계를 유발하고 있는 동시에, 네번째로 북한의 지속적인 핵과 미사일위협이 지역을 넘어 범세계적인 위협요인으로 작용하고 있으며, 다섯 번째로 장기간 미해결상태에 있는 도서 분쟁이 항시 관련국가들 사이에서의 과도한 민족주의적 갈등을 유발시키고, 이로 인한 적대적인 갈등관계가 지속되고 있는 점 등을 동시대적인 현실적 차원에서의 정치적 장애요인들로 규정해 볼 수 있다. 동시에 이런 현실적 차원에서의 정치적 장애요인들의 근원적인 발생요인으로도 평가될 수 있으며, 특히 동북아 개별국가들이 내세우고 있는 강력한 민족주의 성향과 과거사와 연관된 역사인식에 따른 문화적 이질성의 내면에 존재하는 낭만적 민족주의요소가 동북아 개별국가들 간의 신뢰형성과정을 강력하게 가로막고 있음을 지적할 수 있다. 19세기말에 동북아에 유래된 낭만적 민족주의에 대한 비교국가 차원에서의 심도 있는 분석과 이를 통한 절충점의 발견은, 역설적이지만, 세계 어느 지역보다도 극심한 갈등과 대립국면이 심화된 동북아지역 내의 국가들이 군사안보 및 정치경제차원에서의 보다 원활한 협력관계를 도모하기 위한 첫 단계로서의 공동의 장을 마련할 수 있는 주요한 동기가 될 수 있다.

New information communication technologies are changing our society completely, offering the government new possibilities for providing citizens and businesses with better, and more efficient E-Government services. This study analyzes the direct and indirect impact of service value, innovativeness, and users' participation level on the trust toward the Government. Results from a citizen survey indicate that service value, innovativeness, and participation positively affect the trust toward the Government, and that innovativeness has been found to affect service value as well as the level of participation. However, the moderating effect of political efficacy on the relationship between two variables(service value and participation) and trust have been found to be insignifcant. Several other findings and policy implications are also discussed.

This article reviewed the status of military force on the DMZ(demilitarized zone) without any confidential problems after literature reviewing on a ceasefire agreement and these powerful military force is judged to be a very serious setback to peaceful reunification of the Korean Peninsula. Also it suggests the ways to reduce inter-korean military force based on the political and economic phenomenon to preparing for an era of reunification of the Korean Peninsula. The easing of tension on the inter-korean military force is an essential element in building infrastructure of peaceful reunification. From now on, both Seoul and Pyongyang might check inter-Korea exchange cooperation Project and reconcile their differences. Primarily, The troops of DMZ would be minimized by Modernization for Military confidence-building. Increasing North-South hotline as possible further, it could contributes to ease of tension in case of emergency. Political and economic plans should be presented that do not arise the military tension simultaneously with ensuring political and economic aspects in the North Korea's regime.

The probability of causation(PC) is the measure to ascertain the likelihood that a particular cancer may be attributed to a particular prior exposure to radiation. Since the PC is involved in several uncertainties, it is desirable to use the confidence limit for the PC, not a point estimate for determining whether to award compensation. We developed the program for estimating the PC to Korean radiation workers with cancer, the so-called RHRI-PEPC, which is based on the most reasonable model for radiation cancer risk and recent Korean baseline data. RHRI-PEPC gives us the upper confidence limit for the PC after adjusting several uncertainties and therefore we can assess more reasonably the causality of radiation exposure for cancer occurred in Korean radiation workers.

This study examines the trend and issues of sociological studies of social network service(SNS). For this purpose, the studies were classified into three types. The first type of study concerns spatial characteristics of SNS. It deals with the impact of such SNS usage on individual attitudes and behaviors. The second type of the study focuses on the formation process of interrelationship among users. It is based on sociological concepts such as trust and social capital. The last type of study emphasizes the impact of SNS on society. The study includes the issues of social movement and political participation. In the future study of SNS, more diverse sociological subjects, such as social integration, exclusion, public welfare, and affective support need to be dealt with.

This paper explored the impact of adaptive efforts for the 4th Industrial Revolution(hereafter, 4IR) on social cohesion at national level. To examine this relationship, Latent Growth Model was applied to thirty one OECD membership countries, 2006-2015. Adaptive efforts for 4IR was measured by the 4IR Relative Readiness(WEF, 2016) and social cohesion was measured by Corruption Perception Index(Transparency International) and trust on politicians(WEF). Results showed that corruption perception significantly decreased by the 4IR Relative Readiness and legal protection(judiciary independency and corporate ethics) and trust on politicians significantly increased by judiciary independency. These results imply that public and corporate efforts for the 4IR does not necessarily have negative impact on social cohesion as long as legal protection such as judiciary independency and corporate ethics are equally pursuit at national level.
