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.

Smokers keep smoking despite knowing that tobacco claims many lives, including their own and others'. What makes it hard for them to quit smoking nonetheless? Tobacco companies insist that smokers choose to smoke, according to their right to self-determination. Moreover, they insist that with motivation and willpower to quit smoking, smokers can easily stop smoking. Against this backdrop, this paper aims to discuss the addictive disease called tobacco use disorder, with an assessment of the addictiveness of tobacco and the reasons why smoking cessation is challenging, based on neuroscientific research. Nicotine that enters the body via smoking is rapidly transmitted to the central nervous system and causes various effects, including an arousal response. The changes in the nicotine receptors in the brain due to continuous smoking lead to addiction symptoms such as tolerance, craving, and withdrawal. Compared with other addictive substances, including alcohol and opioids, tobacco is more likely to cause dependence in smokers, and smokers are less likely to recover from their dependence. Moreover, the thinning of the cerebral cortex and the decrease in cognitive functions that occur with aging accelerate with smoking. Such changes occur in the structure and functions of the brain in proportion to the amount and period of smoking. In particular, abnormalities in the neural circuits that control cognition and decision-making cause loss of the ability to exert self-control and autonomy. This initiates nicotine dependence and the continuation of addictive behaviors. Therefore, smoking is considered to be a behavior that is repeated due to dependence on an addictive substance, nicotine, instead of one's choice by free will.

Background: Tobacco use is a leading cause of preventable morbidity and mortality from non-communicable diseases. The objectives of the study were to determine the percentage of annual income used to purchase tobacco-related products and treat tobacco-related illnesses, and assess the characteristics of smokers and their awareness of the health-related risks of smoking. Method: Stratified and snowball sampling methods were used to obtain information (via a 17-item, close-ended questionnaire) from 85 adult respondents (49 males and 36 females). The instrument comprised of demographic characteristics, smoking behavioural/lifestyle, health, and micro socio-economics. Results: There were no significant differences between individuals who were affected by chronic obstructive pulmonary disorder (COPD) (14.1%) and cardiovascular disease (18.8%). It was found that respondents spend 30-39% of their annual income on tobacco-related products. Forty percent (40.0%) and 41.7% of respondents with lung cancer and COPD respectively spend more than 50% of their annual income to treat these diseases. The majority (80%) of those who continues to consume tobacco-related products were uncertain as to why they were doing it. Not all the smokers were aware of the dangers of tobacco consumption despite their level of education. Conclusion: The majority of the respondents who had tobacco-related illnesses such as lung cancer and COPD spend a significant amount of their income on their health care. Not all the smokers were aware of the dangers of tobacco consumption despite their level of education. This suggests the need for increase public awareness where both smokers and non smokers are being fully or adequately informed about the dangers or health risks of tobacco consumption.

Purpose: Adolescent suicide is an important issue worldwide. Although literature on preventing suicide among adolescents tends to focus on suicidal ideation, suicidal planning is also an important issue as a stage leading to suicidal behavior. This study aims to identify suicidal planning-related factors, including generalized anxiety disorder, among adolescents who had suicidal ideation. Methods: This secondary study used data generated from the 16th(2020) Korea Youth Risk Behavior Web-based Survey, which included 5,979 students who had suicidal ideation. Factors related to suicidal planning were identified by performing a logistic regression analysis of the participants. All analyses were performed using SPSS 27.0. Results: Among adolescents who had suicidal ideation, 23.8% had suicide plans. The suicidal plans were significantly related to school level (middle, OR=1.38, 95% CI=1.22~1.55), whether they were living with family (no, OR=1.36, 95% CI=1.06~1.75), perceived body image (normal, OR=1.23, 95% CI=1.05~1.44; Obese, OR=1.33, 95% CI=1.14~1.54), depression (yes, OR=1.47, 95% CI=1.25~1.72), tobacco use (yes, OR=1.31, 95% CI=1.12~1.54), alcohol use (yes, OR=1.21, 95% CI=1.06~1.38), drug use (yes, OR=1.96, 95% CI=1.44~2.66), and/or generalized anxiety disorder (severe, OR=1.76, 95% CI=1.44~2.14). Conclusion: The findings of the study suggest that in addition to the commonly recognized factors for adolescent suicide, generalized anxiety disorder should also be considered when establishing strategies to prevent suicide planning in adolescents who had suicidal ideation.

Purpose: This study was conducted to find out the association between dual-use of the electronic cigarette (EC) and conventional cigarette (CC) and depression among undergraduate students. Methods: The participants of this study were 225 undergraduate students who were attending two universities located in Ulsan metropolitan city. Descriptive statistics and multiple regression were conducted to analyze the data. Results: Nicotine dependence and depression were significantly higher in the dual-use group than in the single-use group. Dual-use of the EC and CC was significantly associated with depression among undergraduate students. In addition, quality of sleep was significantly associated with depression among undergraduate students. Conclusion: In order to prevent depression among undergraduate students, it is necessary to improve the awareness of the danger of dual use of the EC and CC.

Despite the various smoking cessation programs that are available for college students, students have lower rates of quitting smoking than do other age groups. This study identifies the variables associated with continuous abstinence from smoking among college students. This study used the data from the National Tobacco Control Center and 781 college students who participated in the program conducted by the Daejeon Tobacco Control Center from June, 2015 to December, 2016. The results showed that the expiration CO level and the frequency of attending smoking cessation counseling were the significant variables related to the continuous abstinence rate at 4, 12, and 24 weeks. Students who had a low expiration CO level (?10 ppm) had a higher abstinence rate than did the students who had a high expiration CO level (≥10ppm), and the OR was 2.53 at 4-week, 2.33 at 12-week, and 2.13 at 24-week. The ORs for the 4-week, 12-week, and 24-week abstinence rates with one additional counseling session were 12.39, 13.13, and 12.21, respectively. This study suggests the need to increase the number of smoking cessation counseling sessions for effective smoking cessation intervention among college students.

Purpose: This study aimed to identify factors influencing nicotine dependence among male college students intending to quit smoking on the basis of the PRECEDE model. Methods: A cross-sectional survey of smokers, enrolled at the Smoking Cessation Support Center in W city in Korea was conducted between September 2015 and December 2016. Data was analyzed using the SPSS program for descriptive statistics, bivariate analyses, and hierarchical multiple regression. Results: The mean score of nicotine dependence was determined to be 2.9. Tobacco craving (β =.34, p<.001), social smoking (β =-.23, p=.004), allowance (β =.22, p=.010) and age of smoking initiation (β =-.20, p=.022) were factors that predicted nicotine dependence of male college students. The final model explained 28.3% of the variation in nicotine dependence (adjusted R2=.28), and was significant (F=7.22, p<.001). Conclusions: We determined that to support smoking cessation, it is necessary to develop anti-smoking programs that consider the social and cultural factors of male college students as well as their personal psychological characteristics.

Water content and its seasonal change in reprodltctive organs were reviewed in relation to cultivation practice s. Precipitati on and humidity under shade roof were reviewed in relation to shading ,jystem and environmental factors. High water content of reproductive organs suggests vulnerability to water stress during reproductive growth stage. Watering during dehisconce treat menu seems to keep optimum temperature but cnoventional practice seems to be too often In watering. Information effe on water physiology of seeds is too rare to develop seed storing method and ctive seed use. Dehiscent mechanism was considered in terms of water absorption of embryo. Precipitation rate of conventional shade roof reaclled to 38% and at line level 50% and varied with shade patterns. Precipitation rate under shade has been investigated for itself but should be investigated in relation to light intensity and soil moisture content Relative humidity under shade depends mainly on air humidity and soil moisture, considerably on shade materials and lithe on pole height, bed width or plant density. Since relative humidity was lower in afternoon it was often less than 50% even in summer with high temperature suggesting possible disorder of phi biological function especially in photosynthesis. More information was needed on optimum humidity for productive physiological function of leaf.

Background: This study investigated whether current smoking and a higher nicotine dependency were associated with chronic low back pain (LBP), lumbar related leg pain (sciatica) and/or radicular neuropathic pain. Methods: A cross-sectional study was conducted on 150 patients (mean age, 60.1 ± 13.1 yr). Demographic data, the International Association for the Study of Pain (IASP) neuropathic pain grade, STarT Back tool, and the Fagerström test were completed. A control group (n = 50) was recruited. Results: There was a significant difference between current smokers and nonsmokers in the chronic LBP group in the mean pain score (P = 0.025), total STarT Back score (P = 0.015), worst pain location (P = 0.020), most distal pain radiation (P = 0.042), and in the IASP neuropathic pain grade (P = 0.026). There was a significant difference in the mean Fagerström score between the four IASP neuropathic pain grades (P = 0.005). Current smoking yielded an odds ratio (OR) of 3.071 (P = 0.011) for developing chronic LBP and sciatica, and an OR of 4.028 (P = 0.002) for obtaining an IASP "definite/probable" neuropathic pain grade, for both cohorts. The likelihood for chronic LBP and sciatica increased by 40.9% (P = 0.007), while the likelihood for an IASP neuropathic grade of "definite/probable" increased by 50.8% (P = 0.002), for both cohorts, for every one unit increase in the Fagerström score. Conclusions: A current smoking status and higher nicotine dependence increase the odds for chronic LBP, sciatica and radicular neuropathic pain.

Background: Although nicotine dependence plays a role as a main barrier for smoking cessation, there is still a lack of solid evidence on the validity of biomarkers to determine nicotine dependence in clinical settings. This study aimed to investigate whether urinary cotinine levels could reflect the severity of nicotine dependence in active smokers. Materials and Methods: Data regarding general characteristics and smoking status was collected using a self-administered smoking questionnaire. The Fagerstr$\ddot{o}$m test for nicotine dependence (FTND) was used to determine nicotine dependence of the participants, and a total of 381 participants were classified into 3 groups of nicotine dependence: low (n=205, 53.8%), moderate (n=127, 33.3%), and high dependence groups (n=49, 12.9%). Stepwise multiple linear regression model and receiver operating characteristic (ROC) curves analyses were used to determine the validity of urinary cotinine for high nicotine dependence. Results: In correlation analysis, urinary cotinine levels increased with FTND score (r=0.567, P<0.001). ROC curves analysis showed that urinary cotinine levels predicted the high-dependence group with reasonable accuracy (optimal cut-off value=1,000 ng/mL; AUC=0.82; P<0.001; sensitivity=71.4%; specificity=74.4%). In stepwise multiple regression analysis, the total smoking period (${\beta}$=0.042, P=0.001) and urinary cotinine levels (${\beta}$=0.234, P<0.001) were positively associated with nicotine dependence, whereas an inverse association was observed between highest education levels (>16 years) and nicotine dependence (${\beta}$=-0.573, P=0.034). Conclusions: The results of this study support the validity of using urinary cotinine levels for assessment of nicotine dependence in active smokers.
