Rapid advances in information and communications technology are new challenges and also opportunities for the police. For the purpose of identifying its implications, this study reviews utilization cases of information and communications technology in the field of public security in South Korea and other countries. As theoretical basis for utilization of information and communications technology, this study introduces intelligence-led policing, predictive policing and evidence-based policing. Also, utilization of big-data based crime analysis and crime prediction technology, as well as advancement of information and communications system and command and control technology of the police, are discussed. Based on the identified implications in this study, the following proposals are made. They are (1) procuring basic data, (2) creating an integrated database, (3) increasing utilization of policy decision-makers, (4) exchange and cooperation between related institutions, (5) training professional analyzers, (6) establishing legal basis and practical guidelines for an integrated database.

The U.S.-China Relations could be analyzed two perspectives and their basis under major international p olitics theory-power transition with conditions: (1) North Korean's nuclear puzzle, (2) THAAD in the Kor ean Peninsula and (3) the U.S.-ROK Alliance. One perspective is the global order dominates the regional order, and then stable regional order comes out. The other is the regional order dominates the global ord er, and China wages a regional hegemonic conflict against the United States. Consequently, America's o verwhelming leadership in North Korean's nuclear, THAAD and U.S.-ROK Alliance as national power is expected to endure. But China also has expected empowerment and cooperation for the peace and stabilit y on the Korean Peninsula military problems. In this perspective, South Korea needs to pay attention to the changing power distribution and competition between the U.S. and China and needs to strengthen a balancing and harmonious diplomatic strategy, so called 'see-saw diplomacy'.

In this study, we developed a PC - based motorcycle simulator based on the development technology of the virtual patrol motorcycle training system. In order to get the impression that the motorcycle simulator is operating in a realistic way, it is important to have a reliable signal transmission and operation feeling between the driver and the simulator. In order to achieve this, we developed a system that can apply the sub-systems of the actual vehicle to the motorcycle simulator in order to generate the same operation feeling as the actual vehicle. Based on these results, We have developed a method for generating a feedback queue. Vehicle dynamics simulates real-time vehicle motion by receiving input from a steering wheel, accelerating / decelerating pedal, etc. operated by a driver on a vehicle simulator and transmitting the result to a visual and acoustic system, It is the central element of the simulator to generate. I want to summarize the main requirements of simulation dynamics.

The purpose of this study is to research psychosocial experience in post-mastectomy women, who participated in self-help group, using in-depth interviews and participant observations. Until recently, studies on post-mastectomy women in psychological perspectives had been maily done by nurses, and there are only few literatures in social welfare studies. Therefore, based on phenomenological theory, the meaning and essence of "the breast" and the lived experience of post-mastectomy women, i.e. emotional distress, and as a result has been explored, it has confirmed six clusters and explained them in detail. As a result, from the subjects' experience, the essence of 'A crossroad of life and death', 'sexual-identity crisis', 'feeling mortified due to double binded messages of others', 'conflict between physical and psychological disabilities', 'feelings of gratitude or wishfulness', and 'their realistic suggestions and wishes' has been shown. It has been founded that the subjects experienced not only self-identity crisis as women but also unending internal turmoil because of their passion to live. It has been hoped that this study will help to shape government policy and social welfare services on post-mastectomy patients.

This study aims to estimate the trajectory of outpatient medical service use and examine what factors are associated with the trajectory among older adults 60 and over with specific focuses on age variations. Using the first three waves of the Korean Welfare Panel Study data, the trajectory and predictors were examined through the Latent Growth Curve Modeling and age variations were examined through the Multi-group Comparison Analyses. The research model was developed based on the Anderson Model. The results showed that study participants tend to increase outpatient medical service use with years. Individuals 75 or younger presented a much faster increasing rate of medical service use than those 75 and over. Similar to the findings of the previous studies, most predisposing factors, resource factors, and needs factors were found to be associated with the trajectory of outpatient medical service use. Needs factors were more closely associated with the medical service use trajectory than resource factors. With regard to age variations in predictors, few significant age variations were found. Based on the finding of the study, implications and future research directions were discussed.

This article tried to define the relations between knowledge of tuberculosis infection, behavior and prevent behavior of the students of the department of dental hygiene and of non-dental hygiene. The data was collected from May, 2017 to June, 2017. Characteristics relative to variables were measured. As the result, in tuberculosis infection for the students of the department of dental hygiene, the average point was 13.56points for knowledge; 45.75 points for behavior and 41.75points for prevent behavior. In tuberculosis infection for the students of the department of non-dental hygiene, the average point was 12.93points for knowledge; 45.58points for behavior and 42.01 for prevent behavior. As the result of the study, the student's knowledge of tuberculosis had the effect on behavior, but it didn't have the effect on prevent behavior, on the other hand, it had the effect on prevent behavior. The result of this study may be utilized for an educational program for preventing tuberculosis infection of the students.

The authors proposed a new rapid-screening method for more reasonably evaluating seismic capacities of medium and low-rise RC buildings controlled by both shear and flexure in Ref. [1]. The method proposed in Ref. [1] was based on relationships between required strengths of each failure system for ductility factors and damage degrees of overall system derived from the view-point of ductility factors. The proposed method was also verified using observed real damage data of low-rise RC buildings caused by past earthquakes. Results indicated that the methodology proposed in Ref. [1] compares well with real damages and is a useful strategy for rapidly identifying low-rise RC buildings having high potential seismic risk. In this study, in order to verify the applicability of the new methodology proposed in Ref. [1] to real RC building systems, seismic capacities of existing eleven low-rise RC buildings in Korea are evaluated based on the new method.

As high rise buildings with 100 or more stories are being constructed, it is inevitable to use high performance materials including high performance concrete. What is most important in high performance concrete is extremely high strength in order to reduce the section of members in high rise buildings. During the last several years, there have been active researches on Ultra high strength concrete. While these researches have been mostly focused on strength development, however, other accompanying physical properties have not been studied sufficiently. Thus, the present study purposed to obtain and analyze data on the physical mechanical properties of Ultra high strength concrete through experiments and to use the results as basic information on required performance of concrete used in high rise buildings.

This research studied how political online discussion participation and experiencing opinion disagreement during the discussion affect on civic attitudes(interpersonal trust and reciprocity) and civic participation through pretest-posttest control group experimental treatment. For results, first of all, online political discussion positively affects on civic attitude of participants, but it's effect was partial. Next, experiencing opinion disagreement can help to have rather improving civic attitude than reducing civic attitude. Finally, civic attitude consists of interpersonal trust and reciprocity acquired from online discussion also partially and positively affects on civic participation which is more affected by reciprocity than interpersonal trust. Regard to these effect of online discussion, civic attitude can be extended by participating political communication(discussion), and participating communicative associations lead to encourage civic attitude of them and function to reinforce social integration and social ties.
