Objectives: In recent years, multiple studies have investigated the issue of intimate partner violence (IPV) in Korea. However, most of those studies have focused on IPV against women, while overlooking the problem of men IPV victimization. Considering this, the current study identified risk and protective factors for IPV and examined their influence on IPV victimization among Korean men. Methods: We used a nationally representative sample of 1668 Korean men from the 2013 Korea National Survey on Domestic Violence. The associations between potential IPV risk factors and different types of IPV were investigated using univariate and multivariate logistic regression. Specifically, separate analyses were conducted of 5 types of IPV (neglect, controlling behaviors, emotional violence, economic violence, and physical violence). Results: The prevalence of IPV among Korean men and women showed only marginal gender differences. Controlling behaviors (men, 23.3%; women, 23.9%) and emotional violence (men, 16.5%; women, 18.8%) were the most common types of IPV reported, followed by neglect (men, 11.2%; women, 11.7%). Separate logistic regression analyses for the 5 subtypes of IPV revealed that mutual IPV was a strong predictor of IPV. Men who abused their wives were more likely to experience neglect (odds ratio [OR], 29.24; p<0.01), controlling behaviors (OR, 36.61; p<0.01), emotional violence (OR, 58.07; p<0.01), economic violence (OR, 18.78; p<0.01), and physical violence (OR, 38.09; p<0.01). Conclusions: The findings of this study suggest that IPV intervention strategies should particularly focus on couples whose relationship is characterized by patterns of bidirectional violence.

In the plant EPC project, the procurement work can be considered as the most important part that affects the success or failure of project as it has the closest mutual influence in every execution process of the project. Procurement takes up generally 60% ~ 70% of the entire project budget and the current trend of plant EPC project becoming larger in scale and a variety of process technology being applied. So, it is needed to identify the risks that are expected to occur according to the stages of procurement work, namely, proposal stage, manufacturer selection and purchasing agreement stage, expediting the process management of manufacturer stage, inspection stage and logistics & transportation stage. The management of observation and control of the risks should be performed with the response techniques which are 'avoid',' transfer'and' mitigate'.

This paper describes the Autonomous Vehicles (AV) which are operated for their own tasks. There are chances of conflict resolution such as sharing the same path which can lead to the risk of a collision. This research represents some ways of negotiating the conflict resolution by generating cooperative actions. Negotiation while traveling the path is accomplished by using priority and by announcing the start time of the task. When there is a risk of collision, the AV tries to dissolve the situation of conflict resolution by concurrently adjusting mutual speed and by performing the algorithm of passing. If the speed of the AV cannot be adjusted, it measures the distance between the counterpart of the AV and an obstacle along the path. Then it judges either to proceed by passing the counterpart of the AV or to turn back after observing the current circumstances. The performance of the algorithm described above was proven by a simulator.

Objective: Endometritis is a major disease, that causes infertility in cattle, and is usually categorized as clinical or subclinical endometritis (SCE). The nutritional condition during the dry period is important for recovery after the last stage of the lactation period, and for postpartum production and reproduction. This study aimed to clarify the relationship between nutritional and metabolic characteristics in the dry period, and the risk of postpartum SCE. Methods: Multiparous Holstein dairy cows (n = 25, raised in a tied stall) were used. Endometrial cytological analysis was performed around 30 days post-partum, with 5% to 14% polymorphonuclear (PMN) as a cut-off point to define SCE. Serum levels of glucose, non-esterified fatty acids, β-hydroxybutyric acid (BHBA), blood urea nitrogen, total cholesterol, aspartate aminotransferase, γ-glutamyl transpeptidase, calcium, phosphorus, and magnesium were measured in the cows at the dry period to evaluate energy status, protein metabolism, and mineral metabolism. Results: The incidence of SCE in the cows was 60.0% (n = 15/25) and the mean PMN% in postpartum cows diagnosed as SCE was 8.05%±2.6%. Overall, 17 and 8 samples were collected from the cows in the far-off and close-up periods, respectively. The serum concentration of BHBA in the far-off period and serum glucose concentration in the closeup period were correlated with postpartum PMN% (r = 0.62, p<0.01; r = -0.74, p<0.05, respectively). Serum levels of calcium and magnesium in the dry period were associated with the incidence of postpartum SCE (healthy vs SCE cows, p<0.05). Conclusion: Blood levels of glucose, BHBA, calcium, and magnesium in dry periods could be useful parameters for predicting the risk of postpartum SCE. The present study also suggests that management in the close-up period is essential for promoting recovery from calving fatigue.

본 연구의 목적은 사회신뢰가 위험인식에 미치는 효과를 분석하는 것이다. 즉, 서울시민들이 가지고 있는 다른 사람들에 대한 일반화된 신뢰가 위험요인에 대한 인식에 어떤 영향을 미치는지를 실증적으로 분석하고자 하였다. 먼저 서울시민들이 일상생활에서 마주치는 위험요인을 자연재해, 기술적 재난 위험, 경제적 위험, 사회해체 위험, 건강상 위험 등 다섯 가지로 구분하였다. 그런 다음 각각의 위험요인에 대한 사회신뢰의 영향력을 다중회귀모형으로 분석하였다. 그 결과, 사회신뢰는 모든 유형의 위험요인에 대해 유의미한 음(-)의 영향을 나타냈다. 이러한 결과는 사회 내에서 익숙하지 않은 사람들을 믿는 사회신뢰가 높을수록 위험요인을 덜 위험하다고 평가하는 것을 의미한다. 본 연구의 시사점은 현대 위험사회에서 위험에 대한 책임이 중앙 및 지방정부에게 주어져 있는데, 효과적인 위험 예방활동과 함께 근거 없는 위험의 확산을 막기 위해 사회신뢰를 증진시키는 노력이 필요하다는 것이다. 또한 사람들 사이의 신뢰는 위험에 대처하는데 있어 협력을 촉진하므로 사회신뢰를 형성할 수 있는 소통의 장을 마련하여 상호이해를 도모할 필요가 있다.

사물인터넷(IoT)은 다양한 디바이스와 일상적인 물건을 인터넷 연결하여 인터넷을 확장한 것이며, 전자제품에는 인터넷 연결이 가능하고 다양한 형태의 하드웨어가 내장되어 있다. 이러한 사물인터넷은 디지털 생태계에 중대한 위험을 초래한다. 이들 기기 중 상당수는 공격자의 공격을 막기 위한 보안 시스템이 내장되지 않은 상태로 설계되어 있기 때문이다. 본 논문에서는 사물인터넷 디바이스를 위한 대칭키 기반의 상호인증 프로토콜을 제안한다. 제안 프로토콜은 대칭키 암호 알고리즘을 사용하여 무선상에 전송되는 데이터를 안전하게 암호화한다. 아울러 암호화에 사용된 비밀키는 매 통신마다 디바이스가 생성하는 난수를 비밀키로 사용하여 고정적으로 사용되는 비밀키를 가변적으로 사용함으로써 보안성을 높였다. 제안 프로토콜은 무선상에서 데이터를 전송하기 전에 상호인증 과정을 거쳐 인증된 디바이스만 데이터를 전송하기 때문에 공격자를 차단하고 정상적인 디바이스가 통신이 가능하도록 하였다. 마지막으로 제안된 프로토콜을 공격유형별 시나리오를 통해 도청 공격, 위치추적, 재전송 공격, 스푸핑 공격, 서비스 거부 공격에 안전함을 확인하였다.
