In accordance with the appearance of global issue called Sustainable Development Goals (SDGs), United Nations Forum on Forests (UNFF) has shown a significant progress in such as emphasizing the potential contribution of forest sector and establishing long-term strategies. In relation to the SDGs which would be discussed mainly in different international agreements and conferences related to forest sector until 2030, this study reviewed the discussion trend by establishing integrated databases and focusing on UNFF which serves as an integrated coordinator. It also aims to identify the meaning of United Nations Strategic Plan for Forest (UNSPF) established by UNFF. Furthermore, the following proposals on policies are presented in this study aiming for active discussion on forest sector not only in international but also in national context, and to implement UNSPF and GFGs effectively in a long-term manner: (1) Cooperation among sectors, organizations, and countries is more important than anything to make an active discussion on forest sector; (2) Recognizing and understanding the role and contributions of forests should be encouraged in actual field, and it should serve as the basis when establishing national policies and goals; (3) By fully utilizing UNFF report which is for the review of UNSPF implementation, a rational reporting system should be provided, and simultaneously, the efficiency on reporting items in the process of implementation should be improved.

Vietnam is one of the countries most affected by climate change. Therefore, communication activities on climate change in Vietnam are focused with various media such as television, newspapers, radio, internet etc. In particular, Facebook social network is a potential media but less interested and developed. In this topic, Audience Insight tool of the Facebook social network and the online sociological survey method were conducted to assess the current status and effectiveness of climate change communication activities via Facebook in Vietnam today. Vietnam ranks seventh in the world with 58 million users. However, the number of climate change communication fanpages has only about 15 fanpages with the largest number of followings is 94,721 persons. Among of the 10 most contented Facebook users in Vietnam today, there is no fanpage related to climate change. The results of research and evaluation two fanpages of climate change communication that are the most and most frequent followers in Vietnam showed that climate change communication via Facebook in Vietnam is not as effective as expected. At the same time, online survey results also pointed out the causes of the above problems. This is the scientific basis for management agencies to find the solutions to promote the strength of Facebook social network in climate change communication in the future.

Low Impact Development(LID) techniques has been attracting attention as a countermeasure to solve frequent flood damage in urban areas. LID is a techniques for returning to the natural hydrological cycle system by infiltrating the runoff from the impervious surface into the soil. The Bio-retention, one of the LID element technology has outflow reduction effect by reserving and infiltrating storm water runoff from watersheds. Recently, a number of studies have been carried out as interest in the reduction of storm water runoff and non-point pollutants in Bio-retention has increased. However, quantitative analysis on the outflow reduction of Bio-retention applied to small watershed is insufficient. In this study, Bio-retention model was constructed in a small watershed using K-LIDM which is capable of hydrologic analysis. When the storage capacity was increased or dividing the Bio-retention and watershed, the outflow reduction effect was 20% according to the storage capacity increase and 5~15% in the distributed Bio-retention system. The results of this analysis will be used as the basic data of future Bio-retention research related to watershed characteristics, vegetation type and soil condition.

Recently, with the development of IT technology, there is an increasing interest in cloud services as the number of users using mobile devices such as mobile phones and tablets is increasing. However, there is a need for techniques to control or control various methods of accessing data as the user's service demands increase. In this paper, we propose a dual key based user authentication model that improves the user 's authentication efficiency by using two keys (secret key and access control key) to access the users accessing various services provided in the cloud environment. In the proposed model, the operation process and the function are divided through the sequence diagram of the algorithms (key generation, user authentication, permission class permission, etc.) for controlling the access right of the user with dual keys. In the proposed model, two keys are used for user authentication and service authorization class to solve various security problems in the cloud service. In particular, the proposed model is one of the most important features in that the algorithm responsible for access control of the user determines the service class of the user according to the authority, thereby shortening the management process so that the cloud administrator can manage the service access permission information of the user.

The purpose of this study was to analyze the characteristics of violent experiences, the types of responses to violent experiences, the coping methods among nurses working in long-term care hospitals. Data were collected using structured questionnaires from 226 nurses in 12 long-term care hospitals in J province. Data collection was performed between April 15, 2016 and April 29, 2016. The data were analyzed by using descriptive statistics and ${\chi}2-test$. Of all the respondents, 55.8% had experienced violence in the past 1 year. Of the perpetrators of the violence, 54.6% and 60.0%, were aged 65 and over and had cognitive functional decline, respectively. The most frequent type of violence was verbal abuse(90.5%). Following the violent experiences, emotional responses had the highest score($2.8{\pm}0.8$). The major coping behavior was "told their peers(84.1%)", followed by "disregarded it and worked although it felt bad(75.4%)". These results indicate the need to establish systems for violence prevention and coping, as well as applicable educational programs, tailored to the circumstances of long-term care hospitals and the characteristics of their patients.

Road lighting is highly preferred as the major nighttime road safety countermeasures. When it comes to the pole-type road lighting, as it's installed at a certain height from the road surface, the driver is dazzled by the light source, interrupting the driver's visibility and furthermore, the light leaks to the area outside the road boundary, worsening the energy efficiency as well as generating the light pollution to the surrounding environment including the animals and plants. The study developed the low-level lighting systems, so it is possible to prevent the lights from being strayed, so there is no any side effects in terms of the sleep deprivation. The study compared the performance as the lightings between low-level lightings and conventional pole based lighting systems. As the results, the low-level lighting systems showed the higher performance in terms of average surface luminance, uniformity, glare compared to the conventional lighting systems.

Roundabouts are generally installed at which traffic and pedestrian volume is relatively small intersections, and hence traffic can flow one direction around a circular island without traffic lights. A number of researches for roundabout signal metering have been processing ways to deal with operation efficiency drops in conditions of unusual traffic and pedestrian volume increases. However, there is still a shortcoming exists in previous operation algorithm does not consider the hidden vehicles between yield lines and detectors and queueing vehicles in circular lanes. These queueing vehicles between them can be cleared by introducing the queue clearance time. The purpose of this research is developing a real time signal metering operation algorithm by considering the vehicle queue clearance time. The results of varying queue clearance time application show that there is a substantial average vehicle delay reduction in VISSIM Com-Interface simulation. When the total number of entering vehicle is 3,200~4,800 vehicle/hour with varying queue clearance time application 21~50 seconds gives average delay reduction per vehicle by 16.1~71.7%.
