This study investigated the differences in health behaviors of adolescents depending on their sexual experiences. Secondary data analysis was conducted using the data of 61,861 respondents from the 2017 adolescents' health behavior online survey in Korea. Adolescents with sexual experience were typically male, in high school, from a boy's school, had low academic performance, lived apart from their parents, and of either high or low economic status; their health behaviors were characterized by more physical activity, stress, sadness and hopelessness, thought/planned/attempted suicide, drinking, and smoking. Almost half of adolescents with sexual experience (48.9%) did not use contraception. The results of this study are significant and can contribute to the development of sex education programs when considering the characteristics of Korean adolescents and their sexual health.

In modern city, art museum is regarded as significant institutions because it includes educational roles beyond the means of facilities for historical exhibitions. Based on these flow, various research of museum's space with view from the operational point to the spatial analysis point has been approached. Moreover, it is required to address human behavior in art museum space on the ground that lots of audience move simultaneously. In the field of interior architecture, it is also necessary to analyze how design elements affect the human behavior directly and use the method of controling a circulation. In this research, based on the role and importance of the basic components of the interior space, re-interprets the exhibition space based on the relevant theory, to comprehensively examine the influence the shape of the space is on the substantially walking behavior. Therefore, first is to determine whether the spatial type corresponding to the position of the connectors in the exhibition space. Second is to conduct the investigation observation for gathering the actual viewing exhibition circulation. Finally, it analyzed whether the observed actual circulation and planned circulation matched. As the result, the position of the connectors is that causes the difference of the spatial configuration, which affects the viewing circulation was found. The significance of the research is to present the form to plans of the interior space as a method of reducing congestion perception of viewing circulation.

Objectives: This study was intended to provide resources for the development and operation of the elderly's oral health education programs by comparing the difference of oral health behavior, oral health care self-efficacy and oral health levels according to their oral health education experiences and by researching the correlation of oral Health Behavior, self-efficacy, subjective oral health level and oral health education experience. Methods: An interview survey using structured questionaries was done on 180 senior citizens older than 65 years old residing in some areas of Gyeonggi-do from April 19 to May 25, 2018. The data was analyzed with Chi-square, t-test, spearman correlation coefficient with the use of SPSS 20.0. Results: 1. Those who are older than 75 years old and have higher levels of education and finance have more experiences of oral health education. 2. Those who have experiences of oral health education brush their teeth more than three times a day, use more oral health care items and get more regular preventive treatments such as oral examination and scaling. 3. As they has experiences of oral health education, their oral health behaviors, oral health care self-efficacy(tooth care, dietary control, regular checkup) and subjective oral health levels are high. Conclusion: It is necessary to try to improve the elderly's oral health levels by motivating the importance of oral health care and changing their oral health behaviors positively with the implement of oral health education on the elderly. Especially, oral health education programs that are operated on the elderly should be planned with practical programs that can cause the change of their oral health behaviors and should be processed to reinforce oral health care self-efficacy. Furthermore, preventive treatments for the elderly such as oral health education, oral examination and scaling should be implemented systematically and continuously by policy.

In this paper, the security behaviors and attitudes related with the personal information of teenagers were investigated using empirical data based on rational behavior theory and protection motivation theory. An experiment for teenagers was conducted on Excel and the statistical packages (i.e., SPSS 21.0 and SmartPLS2.0.M3) to see how self-efficiency, security attitude, security intention and individual innovation affect their security behaviors. The experimental results showed that the security behaviors and attitudes of teenagers between internet and information devices are closely related, and the social influences can affect personal self-efficacy and security attitudes. Finally, we can know that teenagers should recognize the importance of security and protect their personal information safely through continuous education and training so that they can be linked to security behaviors.

The rock anchorage of a suspension bridge is an outstanding anchorage type from environmental and economical perspective, although it should be applied when the bearing foundation is fresh enough to resist large cable loads. In practice, geotechnical engineers have encountered difficulties in designing the anchorage structure due to the fact that the physical behaviors of rocks against cable loads have not yet been fully proved and its design method was not established yet. In this study, model tests and numerical studies were performed to evaluate the behavior of the rock anchorage system planned under hard rock layers in domestic islands, and results suggest that the shape of asymmetric rock wedges can resist the tension loads with self weight and shear resistance. Additionally, real scale trial tests were carried out to verify the accuracy of an inclined drilling penetrating hard rock layers to install tendon to the bearing plate.

This paper reports a technique that automatically extracts object shapes through Dense-Net, and subsequently, detects the objects using Mask R-CNN in a manufacturing site, in which workers and objects are mixed. It is based on the customized factory dataset by targeting workers, machines, tools, control boxes, and products as the objects. Mask R-CNN supports multi-object recognition as a well-known object recognition method, while Dense-Net effectively extracts a feature from multiple and overlapping objects. After immediate implementation using the two technologies, the object is naturally extracted from a still image of the manufacturing site to describe image. Afterwards, the result is planned to be used to detect workers' abnormal behavior by adding a label on the objects.

The purpose of this study was to verify the correlation between variables that affect the intention to continue using medical information service applications. Then, we established a research model based on ETPB and conducted an empirical study using PLS-SEM.According to the empirical analysis results, First, intimacy, prior knowledge, and cost saving were confirmed to have a significant impact on the TPB variables such as attitude, subjective norm, and perceived behavioral control. Second, it was confirmed that TPB variables had a significant impact on behavioral intention, and behavioral intention had a significant impact on continued use intention. Third, it was confirmed that familiarity, prior knowledge, and cost saving had a significant impact on the intention to continue use through the mediation of behavioral intention based on the perception shift of medical consumers. The significance of this study is that it empirically investigated the behavior of medical consumers by deriving the impact on their intention to continue using medical information service applications through their behavioral intentions.

Objectives: This study investigates the current state of consuming breakfast among elementary school students residing in Malang, East Java, Indonesia, and to identify factors that influence breakfast behavior. Methods: The research model was set up as per the health belief model, and slightly modified by adding the subjective normative factors of the theory of planned behavior. The survey was conducted from July 17 to August 15, 2017 using a questionnaire, after receiving the permission PNU IRB (2017_60_HR). Results: The subjects were 77 boys (49.4%) and 79 girls (50.6%) suffering from malnutrition with anemia (21.2%) and stunting ratio of Height for Age Z Score (HAZ) (11.5%). Furthermore, moderate weakness (14.8%) and overweight and obesity (12.3%) by Body Mass Index for Age Z Score (BMIZ) were coexistent. According to the results obtained for breakfast, 21.8% did not eat breakfast before school, with 18.8% of the reasons for skipping breakfast being attributed to lack of food. Even for subjects partaking breakfast, only about 10% had a good balanced diet. The average score of behavioral intention on eating breakfast was 2.60 ± 0.58. The perceived sensitivity, perceived severity, perceived benefits, and self-efficacy of the health belief model correlated with breakfast behavior. Of these, self-efficacy (β=0.447, R²=0.200) and perceived sensitivity (β=0.373, R²=0.139) had the greatest effect on breakfast behavior. Mother was the largest impact person among children. Conclusions: In order to increase the level of breakfast behavior intention among children surveyed in Indonesia, we determined the effectiveness by focus on education which helps the children recognize to be more likely to get sick when they don't have breakfast, and increase their confidence in ability to have breakfast on their own. We believe there is a necessity to seek ways to provide indirect intervention through mothers, as well as impart direct nutrition education to children.

This study examined the associations among the factors related to self-care behavior in patients with liver cirrhosis, focusing on disease knowledge and family support. The subjects were 120 liver cirrhosis patients recruited from the medical out-patient clinic of ageneral hospital in the U metropolitan city during the period of June-August, 2015. The data were analyzed with SPSS(Version 21) program. The results showed that the average scores of disease knowledge was $12.64{\pm}2.16$ out of 18; family support was $23.28{\pm}5.68$ out of 32; and self-care behavior was $35.66{\pm}8.67$ out of 60. The study subjects had moderate levels of disease knowledge and family support, but low levels of self-care behavior. The data showedthat self-care behavior was positively correlated with disease knowledge (r=0.675, p<0.001) and family support (r=0.804, p<0.001) of the subjects. The best predictors for self-care behavior were family support, disease knowledge, frequency of alcohol consumption per week, having liver cirrhosis patients among family or relatives, and educational level, which accounted for 69.7% of the variance. In conclusion, promoting the self-care behavior of liver cirrhosis patients should be planned based on a consideration of the patient's educational level, knowledge of their own disease, and family support.

Financial firms, especially large scaled firms such as KB bank, NH bank, Samsung Card, Hana SK Card, Hyundai Capital, Shinhan Card, etc. should be securely dealing with the personal financial information. Indeed, people have tended to believe that those big financial companies are relatively safer in terms of information security than typical small and medium sized firms in other industries. However, the recent incidents of personal information privacy invasion showed that this may not be true. Financial firms have increased the investment of information protection and security, and they are trying to prevent the information privacy invasion accidents by doing all the necessary efforts. This paper studies how effectively a financial firm will be able to avoid personal financial information privacy invasion that may be deliberately caused by internal staffs. Although there are several literatures relating to information security, to our knowledge, this is the first study to focus on the behavior of internal staffs. The big financial firms are doing variety of information security activities to protect personal information. This study is to confirm what types of such activities actually work well. The primary research model of this paper is based on Theory of Planned Behavior (TPB) that describes the rational choice of human behavior. Also, a variety of activities to protect the personal information of financial firms, especially credit card companies with the most customer information, were modeled by the four-step process Security Action Cycle (SAC) that Straub and Welke (1998) claimed. Through this proposed conceptual research model, we study whether information security activities of each step could suppress personal information abuse. Also, by measuring the morality of internal staffs, we checked whether the act of information privacy invasion caused by internal staff is in fact a serious criminal behavior or just a kind of unethical behavior. In addition, we also checked whether there was the cognition difference of the moral level between internal staffs and the customers. Research subjects were customer call center operators in one of the big credit card company. We have used multiple regression analysis. Our results showed that the punishment of the remedy activities, among the firm's information security activities, had the most obvious effects of preventing the information abuse (or privacy invasion) by internal staff. Somewhat effective tools were the prevention activities that limited the physical accessibility of non-authorities to the system of customers' personal information database. Some examples of the prevention activities are to make the procedure of access rights complex and to enhance security instrument. We also found that 'the unnecessary information searches out of work' as the behavior of information abuse occurred frequently by internal staffs. They perceived these behaviors somewhat minor criminal or just unethical action rather than a serious criminal behavior. Also, there existed the big cognition difference of the moral level between internal staffs and the public (customers). Based on the findings of our research, we should expect that this paper help practically to prevent privacy invasion and to protect personal information properly by raising the effectiveness of information security activities of finance firms. Also, we expect that our suggestions can be utilized to effectively improve personnel management and to cope with internal security threats in the overall information security management system.
