Purpose: This study was to explore adaptation experience to family among women who immigrated for marriage. Specific aims were to identify problems immigrant women face as family members and how they interact with other family members. Methods: Grounded theory methodology was utilized. Data were collected from iterative fieldwork with individual in-depth interviews from 6 immigrant women as key informants, and 2 of their husbands and 2 of their mothers-in-law as general informants. Results: Through constant comparative analysis, a core category emerged as "tearing down the wall in communicating". Causal conditions were feeling frustrated in one's expectations, differences in language and life style, differences in recognition, and perceptions of discrimination and prejudice. Strategies were learning the Korean language, learning Korean culture, managing stress, mediating differences between family members, and introspecting. Intervening factors were support systems, burdens of child-rearing, and the condition of one's health. Consequences were rooting oneself in one's family and accepting one's life as it is. Conclusion: Results of the study indicate that there is a need for nurses to understand differences in communication with family members among immigrant women and to provide information and emotional support to improve the adaptation of these women to their Korean families.

Communication in delay tolerant networks (DTNs) relies on message transport by mobile nodes, and a correct understanding of the node mobility characteristics is therefore crucial to the design of an efficient DTN routing protocol. However, previous work has mainly focused on uncovering all behaviors of node movement, which is not conducive to accurately detecting the specific movement characteristics of a different node. In this paper, we seek to address this problem based on a consideration of social relationships. We first consider social ties from both static and dynamic perspectives. For a static perspective, in addition to certain accidental events, social relations are considered for a long time granularity and tend to be stable over time. For a dynamic perspective, social relations are analyzed in a relatively short time granularity and are likely to change over time. Based on these perspectives, we adopted different efficient approaches to dividing node pairs into two classes, i.e., familiar and unfamiliar pairs. A threshold approach is used for static social ties whereas a density-based aggregation method is used for dynamic social relationships. Extensive experimental results show that both familiar and unfamiliar node pairs have the same inter-contact time distribution, which closely follows a power-law decay up to a certain point, beyond which it begins to exponentially decay. The results also demonstrate that the inter-contact time distribution of familiar pairs decays faster than that of unfamiliar pairs, whether from a static or dynamic perspective. In addition, we also analyze the reason for the difference between the inter-contact time distributions of both unfamiliar and familiar pairs.

We investigated the dielectric relaxation properties $0.5Ba(Zr_{0.2}Ti_{0.8})O_3-0.5(Ba_{0.7}Ca_{0.3})TiO_3$ ceramics with CuO addition. With increasing CuO addition, the lattice parameter was increased by substitution of small amount $Cu^{2+}$ ion in B-site of $0.5Ba(Zr_{0.2}Ti_{0.8})O_3-0.5(Ba_{0.7}Ca_{0.3})TiO_3$ ceramics. Also the grain size and the maximum dielectric constant of $0.5Ba(Zr_{0.2}Ti_{0.8})O_3-0.5(Ba_{0.7}Ca_{0.3})TiO_3$ ceramics was decreased with increasing amounts of CuO addition. Moreover, the diffused phase transition properties (${\gamma}$) of $0.5Ba(Zr_{0.2}Ti_{0.8})O_3-0.5(Ba_{0.7}Ca_{0.3})TiO_3$ ceramics was increased by compositional fluctuation with increasing of CuO amount, changed from 1.45 at 1 wt% CuO addition to 1.94 at 7 wt% CuO addition.

제4차 산업혁명 시대로 불리는 초연결-초지능 사회의 출현은 안보 환경의 새로운 변화를 가져왔다. ICT(정보통신기술) 융 복합 하이테크 기술이 전 방위적으로 도입되면서 현실 공간을 움직였던 사람 중심의 동력은 코드를 중심으로 한 사이버 공간으로 대체되고 있으며, 그 의존도는 계속 높아지고 있다. 하지만 이러한 기술적 변화는 역설적으로 우리 사회를 위협하는 또 다른 안보취약점으로 작용하고 있으며, 과학기술이 가져온 기회와 도전을 동시에 직면하며 사이버 방어체계를 구축해야 하는 당위성을 가져왔다. 이에 본 연구에서는 갈수록 지능화되고 대규모로 진화하고 있는 사이버 공격에 적극적으로 대응할 수 있는 이론적 근거로 정당방위 이론을 제시하였고, 이에 대한 자주적 사이버 안보전략 수립 방향으로 첫째, 사이버 안보법 제정의 필요성 둘째, 미국 등 사이버 강대국들과의 대응공조 체계 마련 셋째, 사이버 인력을 어떻게 양성할 것인가에 대한 방안 마련을 제언하였다.

Objectives: In this study, we investigated an assessment for exposure levels of hazardous substances to kids cafes that unregulated by law. Methods: Heavy metals, volatile organic compounds, formaldehyde, pesticides and phthalate were measured at 20 kids cafes in Gyeonggi-do and Incheon. Samplings were conducted from April to July in 2018. Results: Heavy metals were detected over the standard mainly around the floor and walls in the 19 kids cafes. Pesticides were detected in 7 locations with chlorpyrifos, diazinon and cypermethrin, and showed the highest detection level of chlorpyrifos. The concentrations of DEHP in all kids cafes were exceeded with standard. The risk assessment results showed that HCHO as carcinogen had a safety level and DEHP as non-carcinogens had a safety level as assessed to be under than 0.1. Conclusions: Considering the exposure investigation results and the importance of child health protection, kids cafe should be included in the legal management list of children's activities zones.

This study analyzed the smart construction safety cost included in safety management plans that are approved before construction. Specifically, it refers to the cost incurred in constructing and operating a safety management system using wireless communication and facilities. Based on the obtained statistical results, an activation policy for the inclusion of the smart construction safety cost in building safety management plans was proposed. The smart construction safety cost must be included in the safety management cost; notably, this is mandated by the Construction Technology Promotion Act. However, there are some problems with the inclusion of smart construction safety costs. To analyze the problems encountered when calculating the smart construction safety cost and including it in safety management plans, in this study, statistical analysis was performed using the data of 1,334 safety management plans received at the Construction Safety Management Integrated Information (CSI) from June to August 2021. The results show that only 50.7% of the safety management plans included the smart construction safety cost although the current law mandates 100% inclusion of these costs. Thus, it is apparent that the smart construction safety costs are only included in a low proportion of sites. In addition, the calculated smart construction safety costs were shown to have a small correlation with the construction cost; moreover, they appeared to be distributed at a constant cost level. In this context, it is believed that perfunctory cost calculations were performed at most sites since the effect of the construction cost on the smart construction safety cost was negligible. Therefore, it is necessary to improve the inclusion of smart construction safety costs by strengthening the authorization process of the approval institute of safety management plans. In addition, institutional support, such as guidelines that promote the calculation and inclusion of appropriate smart construction safety costs according to the characteristics of sites, are needed.

Recently, worldwide to respond to climate change and secure sustainability. Korea aimed to increase water use efficiency by implementing integrated management according to the water management unification policy. Therefore, the necessity of establishing and operating governance is expanding to ensure the sustainability of agricultural water. In this study aims to evaluate the importance of agricultural water governance components and provide essential data for the participation of stakeholders in the efficient use of agricultural water in Korea. For this study, a total of 19 respondents to the ANP survey for this study were composed of experts in agricultural water and governance in Korea. As a result, the ranking for the main components was in the order of law, policy, and systems(0.222), core subjects(0.191), information sharing and communication(0.180), budget support(0.178), mutual learning(0.124), and external experts(0.105). The most important components for the operation of agricultural water governance are laws, policies, and systems. Since Korea's agricultural water management is a public management system, national standards are considered the first priority. This study, which is the purpose of the agricultural water governance model, evaluated the importance of the constituent components for participating in demand management with a sense of responsibility. Moreover, if agricultural water governance is expanded nationwide by reflecting agricultural and water resource policies in the future, it is believed that positive effects can be achieved in increasing utilization efficiency and securing sustainability through agricultural water saving.

오늘날 도시의 규모가 커지고 기능이 복잡해지고 있으며, 다양한 사람들이 다양한 활동을 하며 살아가고 있다. 또한 도시에서의 사람의 삶은 많은 부분에서 주변의 사람과 연관되어 있다. 그리고 도시의 생활은 다양한 인공적인 활동을 하고 있음을 뜻하며, 이에 따른 소리의 발생이 주변사람에게는 소음공해가 되기도 한다. 이러한 이유에서 사람들로 만들어진 인공소음은 특히 서울의 도심 4대문 안의 도로 주변의 소음은 평균 73㏈가 될 정도로 크다. 그리고 도시에 사라는 사람들은 소음공해에 쉽게 노출되며 특히 집회나 시위현장 또는 홍보를 위해 사용되는 확성기들은 상당한 소음을 발생시키며 이는 다른 사람들에게 스트레스를 유발한다. 더욱이, 집회 및 시위에 관한 법률 등에서 지정하는 확성기 사용 및 규제는 있지만 잘 지켜지지 않는 것이 현실이다. 그리고 최근 법령을 -5㏈를 낮추는 등의 법령기준을 강화하였지만, 여전히 스트레스가 되고 있다. 따라서 집회 및 시위현장의 소음의 크기를 제한하고 규제하는 것 뿐만 아니라, 노출되는 시간을 고려하여 피해를 줄이는 것이 더 효과적인 방법이다. 소음으로 인한 스트레스는 짧은 시간만 노출되더라도 오래도록 지속되며, 이러한 환경에 위치한다면, 소음공간에서 빠르게 벗어나는 것을 권장 하는 것도 본 연구에서 제시하는 피해저감 방안이다.
