Public service advertising is a form of communication activity performed to increase public interest. In order to improve the effectiveness of public service advertising, it is necessary to formulate advertising strategies that can actually induce positive action changes. China has various social problems because of dramatic social changes, which call for implementing public service advertising. This study aims to improve the persuasive effects of Chinese public service advertising by addressing effective communication strategies. In particular, we selected 33 works that use fear appeals from 2016 HuangHe Award-winning posters and analyzed their visual representation of fear appeals. The results suggest that fear appeals are frequently used in safe driving and anti-smoking campaigns. In addition, main colors of these posters were black and white. The main fearful images were often represented in a form of 'fact' and 'factual conception' and in the type of 'picture.' They also have features of implicit association' and 'exaggeration'. This study has a significance in terms of providing theoretical and empirical information to future research on improvement of public service advertising in China.

In this paper, correlations between driving parameters and $CO_2$ of light-duty vehicles have been analyzed. Three test vehicles equipped with PEMS (Portable Emission Measurement System) have been driven in real-road in urban areas of Seoul. Averaged vehicle speed, RPA(Relative Positive Acceleration) and stop ratio have been selected as main driving parameters. The analysis have been conducted in interrupted and uninterrupted road types. Averaged values in various driving conditions have been calculated with distance based moving averaging window method. The multiple linear regression method have been applied to account for correlation between driving parameters and $CO_2$ emissions. This approach has shown statistically that $CO_2$ emission per distance (g/km) have tendencies to be increased as decreased averaged vehicle speed and increased RPA and stop ratio. Compared with uninterrupted traffic, interrupted traffic have shown the lower vehicle speed and the higher RPA and stop ratio. These characteristics of driving parameters in interrupted traffic should cause the higher $CO_2$ emission per distance.

Objective : The purpose of this study is to analyze researches about sex education for children and adolescents with developmental disabilities in order to provide a basic data and a direction about sex education. Methods : For the systemic review, domestic and international research articles published from August 2008 to September 2018 were searched using the electronic databases PubMed, EBSCO host (CINAHL Plus with full text), Medline (ProQuest), RISS, and KISS. Keyword used for the search was 'Disability Disorder OR Autism (AND) AND (Effect OR Effectiveness)' for international papers and 'Disability AND Sex Education' for domestic papers. Total 15 articles were collected and analyzed in terms of participant, duration, type, contents, and teaching methods with PICO format. Results : In terms of level of evidence, majority was Level III evidence(60%). Most common contents of sex education were 'physical and growth' and 'relational skills'. Special education and occupational therapy were the field that sex education is provided most frequently. Effects of sex education identified were 'sex knowledge', 'sex attitudes', and 'inappropriate sexual behavior'. Conclusion : This study intend aimed to identify content, trends, and effects of sex education for children and adolescents with developmental disabilities in order to provide a basic data for clinical trial of sex education in occupational therapy practice. This study recommend further researches on the effects of sex education on occupational participation, occupational therapists' awareness of sexual activity of clients, and development of related measurement such as sexual development scale.

The purpose of this study is to contribute to the prevention of ship collisions by investigating real ship collision cases and statistically analyzing causes of human error for captains and Officers of the Watch (OOW). This study encompassed a total of 109 cases for 218 vessels, which were suitable for the analysis of ship accidents between merchant ships or merchant ships and fishing boats over the 7 years from 2010 to 2016. Data was collected while classifying vessels according to type, Give-way and Stand-on vessels, along with the cause of human error. Factors causing human error were identified after focusing on the cause of each collision given by the OOW ; frequency and cross tabulation analyses were conducted using SPSS, a statistical analysis tool. As a result, the main causes of human error by an OOW in a ship collision situation were that lookout was neglected in a Give-way vessel including radar surveillance (74.3 %) or continuous observation of an opponent vessel was carried out (17.4 %). A major factor for Stand-on vessels was failure to act to avoid collision with another vessel (63.3 %). In particular, most neglect for lookout type merchant ships occurred after the opponent ship was first observed, and a common cause of lookout neglect and neglect of duty was a focus on other tasks during navigational watch time.

Changes in water depth caused by underwater earthquakes and landslides cause sea surface undulations, which in turn propagate to the coast and result in significant damage as wave heights normally increase due to the wave shoaling process. Various types of numerical models have been developed to simulate the generation and propagation of tsunami waves. Most of tsunami models determine the initial surface of the water based on the assumption that the movement of the seabed is immediately and identically transmitted to the sea surface. However, this approach does not take into account the characteristics of underwater earthquakes that occur with time history and spatial variation. Thus, such an incomplete description on the initial generation of tsunami waves is totally reflected in the error during the simulation. In this study, the analytical solution proposed by Hammack (1973) was applied in the tsunami model in order to simulate the generation of initial water surface elevation by the change of water depth with time history and its propagation. The developed solution is expected to identify the relationship among various type of seabed motions, initial surface undulations, and wave speeds of elevated water surfaces.

The layout includes various functions not only arrangement, connection, division of information but also affordance and information recognition as the important element that determine the whole structure of information. Recently, the layout of web interface design was gradually changing from the concept of the original Z-layout to F-layout, whereas, it is being changed again into the split layout as the transform of Z-layout. However, there can be lack of grounds as to the reason of the change of layout. Therefore, it needs to study on how the functional difference between the F-layout and Z-layout affects user experience. In this study, we conduct the study on the effect of each layout type on the user experience focusing on the product description of web-page by user test. The user test have shown that the user has better feeling on the split layout based on the Z-layout than F-layout. The Z-layout also has more advantages on the formation of the favorable attitude of user in efficiency, accessibility and concentration. This result is consistent with the trend of web-design to change into the split layout based on the Z-layout and we provided the objective reasons for the effective web-design layout by user test.

The successful aging paradigm suggests that the elderly keep their social ties and actively participate in various activities in later life. Many Korean studies on aging, however, have overlooked the importance of various social activities and relationships beyond kinship. This article aims to investigate the perceived social activities among Korean elders to comprehend the subjectivity of successful aging. 613 respondents, over 50 years old, are selected from a national survey data which was collected by face-to-face interview based on the structured questionnaire. The respondents are classified into pre old (50-64), young old (65-74), old old (over 75). Major findings are as follows. The social activities are grouped into two sub-categories: 'relational activity' and 'productive activity'. The activity types are different by the age cohorts. Various activities are considered in terms of one's needs or motivations, and properly chosen based on the subjective evaluation during life course. Both demographic variables such as sex, area and social context variables such as marital status, living-together show influence on the activity type choices. Plans for later life and work ethics are important as well. Policies regarding social participation emphasizing productivity should positively consider relational motives, as perceived by the Korean elderly.

This paper examines the influence of interpersonal relationship on delinquent behavior among adolescents. The role that parent-child relationship, teacher-student relationship, and relationship with friends play on delinquent behavior is reviewed. Review of empirical studies reveal the following results. First, adolescents who perceive their parents as being hostile and rejecting are more likely to engage in delinquent behavior. Second, those adolescents with parents, who have low expectations and who are less likely pressure them to succeed academically, are more likely to engage in delinquent behavior. Third, adolescents who feel that they have been abandoned by their parents are more likely to engage in delinquent behavior. Fourth, those adolescents with low social support from parents and teachers and high social support from their friends are more likely to engage in delinquent behavior. Fifth, those students who feel hostility from their teachers, have negative relationship with teachers, and experience greater punishment are more likely to engage in delinquent behavior. The results indicate that punishment can have adverse effect on some adolescents, further damaging the teacher-student relationship. Punishment can further reinforce the existing negative cycle that can increase the likelihood of adolescents engaging in delinquent behavior. The results indicate that a lack of support from parents and teacher leads to low academic and self-regulatory efficacy, which leads to low academic performance, which can results in punishments that could further damage their relationship with their parents and teachers and bring them closer to their friends. Adolescents caught up in this negative cycle are more likely to engage in delinquent behavior. These results indicate the need to reform the relational, social, and cultural environment of adolescents who are engaged in delinquent behavior.

This study is aimed to classify teachers' questions and feedbacks as well as students' responses in term, of type and frequency, and speculate the distinctive features of verbal interactions including teachers' questions and feedbacks performed actively in the classes of the gifted in science. The 24 hours of the classes made for the 8th grade science-gifted students were observed and recorded. In addition, the mutual conversations between the teacher and the students were transcribed and analyzed, and the interviews with the teachers also were made. It is found that the teachers usually use the question methods of memory recollection, perception and memorization, together with an instant feedback method, while the students prefer to respond with rather short answers. The characteristic features of the class by the teachers who lead the active class show that they use the open questions at the beginning, raise the level of the questioning, use the questions 'why and how' frequently, and to ask evaluative questions. Their feedbacks to the students interestingly indicate that they show the students the attitude of accepting and receiving students' replies, invite different responses from other students by reserving instant answers or judgements to the students, and give the students the confidence of solving the next problems, by praising and encouraging them.
