In this paper, it is intended to present more reproducible and quantitative method for adhesion assemssement. In scratch test, micromechanical analysis on the stress state beneath the indenter was carried out considering the additional blister field. The interface adhesion was quantified as work of adhesion through Griffith energy approach on the basis of the analyzed stress state. The work of adhesion for DLC film/WC-Co substrate calculated through the proposed analysis shows the identical value regardless of distinctly different critical loads measured with the change of film thickness and scratching speed. On the other hand, uniaxial loading was imposed on DCL film/Al substrate, developing the transverse film cracks perpendicular to loading direction. Since this film cracking behavior depends on the relative magnitude of adhesion strength to film fracture strength, the quantification of adhesion strength was given a trial through the micromechanical analysis of adhesion-dependence of film cracking patterns. The interface shear strength can be quantified from the measurement of strain $\varepsilon$s and crack spacing $\lambda$ at the cessation of film cracking.

Purpose: The purpose of this study was to identify the relationship of knowledge and attitude to temptation toward cigarette smoking in adolescents. Methods: A survey was conducted using a 52-item questionnaire in 2 high school settings. Descriptive statistics, t-tests, ANOVA, post hoc analysis and Pearson correlation coefficients were used with SPSS WIN version 14.0 to analyze the data. Results: There were significant differences in attitude toward smoking and smoking temptation depending on gender, academic performance, religion, current smoking status, parental responses toward smoking, initiation of smoking, and the number of friends who smoke (p<.001). The level of smoking knowledge was not related to any of general characteristics as well as attitude toward smoking and smoking temptation. However, negative attitude toward smoking was moderately correlated with reduced smoking temptation (r=-.608, p<.001). Conclusion: Adolescents' attitude toward smoking and coping ability against smoking temptation were influenced by various factors related to smoking behavior and social situations, rather than by the level of smoking knowledge. In order to develop an effective smoking prevention and cessation program for adolescents, various strategies to change attitudes toward smoking should be included.

Objectives : This study aimed to evaluate the factors influencing health promotion behaviors in elderly men. Methods : We used data from the 6th Korea National Health and Nutrition Examination Survey. We analyzed difference between sociodemographic characters, health statuses, and health promotion behaviors by age. Logistic regression analysis was used to investigate the relation between health promotion behaviors and sociodemographic factors by age. Results : Health promotion behaviors related to aging were weight control effort, health screen examination, smoking cessation, and influenza vaccination. Socioeconomic statuses of elderly men declined from the preliminary age, and health status was influenced by the reduction of social role. Health promotion behaviors such as weight control, health screen examination, and performance of aerobic activities were decreased in men of advanced aged. Conclusions : The health promotion behaviors of elderly men differed significantly with age.

Networked multiple CCTV systems are required to effectively trace down long-term abnormal behaviors, such as stalking. However, the occluding event, which often takes place during tracking, may result in critical errors of cessation of tracing, or tracking wrong objects. Thus, utilizing installed regular CCTVs, this study aims to trace the relation tracking in a continuous manner by recognizing distinctive features of each object and its perspective projection depth to address the problem with occluded objects. In addition, this study covers occlusion event between the stationary background objects, such as street lights, or walls, and the targeted object.

This study evaluated the relationship between drinking and smoking and periodontal disease in Korean elderly people using 2013-2015 National Health and Nutrition Survey. (OR) 1.50; 95% confidence interval [CI], 1.00-2.24) than the non - alcoholic and non - smoking groups. The odds ratios were significantly higher. The odds ratios of periodontal disease were significantly higher in the elderly who were drinking and smoking at the same time than those who did not drink or smoke at all. This study confirms that drinking and smoking are significantly related to periodontal disease. Therefore, it is necessary to strengthen drinking and smoking cessation education to maintain oral health of the elderly.

Objectives: The aim of this study was to identify factors associated with quitting smoking in Indonesia Methods: Data on 11 115 individuals from the fifth wave of the Indonesia Family Life Survey were analyzed. Quitting smoking was the main outcome, defined as smoking status based on the answer to the question "do you still habitually (smoke cigarettes/smoke a pipe/use chewing tobacco) or have you totally quit?" Logistic regression was performed to identify factors associated with successful attempts to quit smoking. Results: The prevalence of quitting smoking was 12.3%. The odds of successfully quitting smoking were higher among smokers who were female (adjusted odds ratio [aOR], 2.69; 95% confidence interval [CI], 2.08 to 3.33), were divorced (aOR, 2.45; 95% CI, 1.82 to 3.29), did not chew tobacco (aOR, 3.01; 95% CI, 1.79 to 5.08), found it difficult to sacrifice smoking at other times than in the morning (aOR, 1.29; 95% CI, 1.14 to 1.46), and not smoke when sick (aOR, 1.32; 95% CI, 1.14 to 1.54). About 59% of variance in successful attempts to quit smoking could be explained using a model consisting of those variables. Conclusions: Female sex, being divorced, not chewing tobacco, and nicotine dependence increased the odds of quitting smoking and were associated with quitting smoking successfully. Regular and integrated attempts to quit smoking based on individuals' internal characteristics, tobacco use activity, and smoking behavior are needed to quit smoking.

Tapentadol is a novel oral analgesic with a dual mode of action as an agonist of the ${\mu}$-opioid receptor (MOR), and as a norepinephrine reuptake inhibitor (NRI) all in a single molecule. Immediate release (IR) tapentadol shows its analgesic effect quickly, at around 30 minutes. Its MOR agonistic action produces acute nociceptive pain relief; its role as an NRI brings about chronic neuropathic pain relief. Absorption is rapid, with a mean maximal serum concentration at 1.25-1.5 h after oral intake. It is present primarily in the form of conjugated metabolites after glucuronidation, and excretes rapidly and completely via the kidneys. The most common adverse reactions are nausea, dizziness, vomiting, and somnolence. Constipation is more common in use of the ER formulation. Precautions against concomitant use of central nervous system depressants, including sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, and alcohol, or use of tapentadol within 14 days of the cessation of monoamine oxidase inhibitors, are advised. The safety and efficacy have not been established for use during pregnancy, labor, and delivery, or for nursing mothers, pediatric patients less than 18 years of age, and cases of severe renal impairment and severe hepatic impairment. The major concerns for tapentadol are abuse, addiction, seeking behavior, withdrawal, and physical dependence. The presumed problem for use of tapentadol is to control the ratio of MOR agonist and NRI. In conclusion, tapentadol produces both nociceptive and neuropathic pain relief, but with worries about abuse and dependence.

This study, as a secondary analysis research, bases its source upon on raw data from the on-line survey of the Korean adolescents' health behaviors in 2015. This study was conducted to clarify the relevance of Korean adolescents' smoking with their health behaviors and mental health, and thus further to provide basic sources of effective education for their smoking prevention and for program development. The results of the study showed that Korean adolescents' smoking was significantly affected by the adolescents' sex, grades, school achievements, types of schools, allowances, economic status, parents' educational background (p<0.001). Meanwhile, smoking based on the characteristics of health behaviors was significantly different according to alcohol consuming experience, families' and friends' smoking, physical activity and subjective health status, and BMI (p<0.001). Smoking characterized by mental health showed the significant difference in their stress recognition, subjective sleep patterns, depressed experiences, suicidal ideation, and subjective sense of happiness (p<0.001). Based on all the factors regarding youth smoking, there should be development and provision of educational program for smoking prevention and cessation, including healthy behavior and mental health improvement for Korean adolescent.
