  • Objectives: An attempt was made to understand the nicotine dependence of smokers selected for an ongoing smoking cessation intervention programme in rural Kerala, India. Methods: Data were collected from resident males in the age group of 18 to 60 years from 4 randomly allocated community development blocks of rural Thiruvananthapuram district (2 intervention and 2 control groups). Trained accredited social health activist workers were utilised to collect data from all groups through face to face interview. Nicotine dependence among participants was assessed by means of the six-item Fagerstrom Test for Nicotine Dependence (FTND) translated into the local language. The internal consistency of FTND was computed using Cronbach's alpha coefficient. Criterion validity (concurrent) was assessed by correlations of nicotine dependence scores with age at initiation of smoking and cumulative smoking volume in pack-years. Results: Among the 928 smokers identified, 474 subjects were in the intervention area (mean age = 44.6 years, SD = 9.66 years) and 454 in the control area (mean age = 44.5 years, SD = 10.30 years). The overall FTND score among current daily smokers was 5.04 (SD: 5.05). FTND scores in the control and intervention areas were 4.75 (SD: 2.57) and 4.92 (SD: 2.51) respectively. The FTND scores increased with age and decreased with higher literacy and socioeconomic status. The average FTND score was high among smokers using both bidi and cigarettes (mean 6.10, SD 2.17). Internal consistency analysis yielded a Cronbach's alpha coefficient of 0.70 in a subsample of 150 subjects, a moderate result. The association of the scale was strongest, with the number of pack-years smoked (rho = 0.677, p < 0.001). Conclusion: A moderate level of nicotine dependence was observed among smokers in the current study. Tobacco cessation strategies could be made more cost effective and productive if a baseline assessment of nicotine dependence is completed before any intervention.

  • It is widely confirmed that online retailers can obtain crucial resources and greater growth potential by depending on the external web portal sites as it is explained in resource dependence theory. Nevertheless, recent studies show that the effect of dependence may not always be beneficial for firms and stress the importance of finding relevant contingent factors. In this study, we identify and suggest that firms' age and niche width strategy, whether generalist or specialist, are contributing factors on moderating the positive relationship between resource dependence and firm growth. To test our hypotheses based on the theory, we have collected monthly web traffic data of online retailers and portals from March 2000 and July 2008. The empirical results lend support to our theory of the firm age having a negative interaction effect on web traffic dependence. Moreover, results verified that positive effect of depending on the portals may become greater if the online retailer is a specialist in terms of niche width.

  • Objectives This study sought to investigate the relationship between age, sex and alterations in levels of % carbohydrate-deficient transferrin (%CDT) and gamma-glutamyl transferase (GGT) in patients admitted with alcohol dependence. Methods The study retrospectively enrolled 187 patients who were diagnosed with alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders-Fourth edition (DSM-IV) and were admitted into a closed ward in Hallym University Hangang Sacred Heart Hospital from 2009 to 2012 and Hallym University Kangnam Sacred Heart Hospital from 2012 to 2017. Demographic factors (age, sex) and biochemical markers [%CDT, GGT, mean corpuscular volume (MCV), aspartate transferase (AST), alanine transferase (ALT)] were collected by reviewing medical records. Alterations in the levels of %CDT and GGT in different groups for each demographic factor were compared after correcting for confounding variables (age, initial %CDT, GGT, MCV, AST, ALT). Results Decreased %CDT and GGT were observed during the period of abstinence after admission. The normalization period for %CDT increased with age, while the normalization period for GGT was longer in female patients. Conclusions These results suggest that alcohol-dependent patients that vary in age have different alterations in %CDT, while different sexes have different alterations in GGT. Age and sex can be potential indicators of treatment response after abstinence in patients with alcohol dependence. Further studies are needed to evaluate the relationship between these factors with regards to physiological and hematological changes in alcohol dependence.

  • Purpose: The purpose of this study was to identify factors which differentiate ex-smokers from smokers among patients with cardiovascular disease. Ex-smokers were patients who abstained from smoking for at least 6 months. Method: The subjects were 92 male cardiovascular patients who try to quit. The stepwise discriminant analysis was used to identify predictors of smoking cessation. Result: 1. The ex-smokers(n=47) and smokers(n=45) were significantly different regarding the age, duration after diagnosis, nicotine dependence, family support for smoking cessation, and intention-to-quit. 2. The family support for smoking cessation, intention-to-quit, nicotine dependence, and age were the predictors which differentiate ex-smokers from smokers among cardiovascular patients. The percentage of grouped cases correctly classified was 92.4%. Conclusion: The higher the family support for smoking cessation, intention-to-quit, age and the lower the nicotine dependence, the more likely these smokers were to success smoking cessation.

  • Drop-shipping is a commonly adopted online-order fulfillment strategy in the Internet age. In this practice, online retailers leverage the fulfillment capabilities of suppliers to fulfill orders. On the other hand, purchase dependence is a frequent phenomenon and is characterized by the purchase of certain items together due to their unknown interior associations. Although this concept has been significantly examined in the marketing field (e.g. market basket analysis), it has largely remained unaddressed in operations management. This paper develops an (R, T) model to address an environment in which unmet demand orders are partially lost and partially backordered when purchase dependence exists. The partial backorders are fulfilled by a drop-shipping option. Through computational analyses, this paper demonstrates the effect of both drop shipping on a partial backordering and purchase dependence. The results shows that more profit can be realized by utilizing a drop-shipping option under purchase dependence.

  • Purpose: The Purpose of this study was to analyze factors influencing the dependence of the elderly. Method: This research was designed as a descriptive study. The subjects were 103 elders living in Seoul. Data were collected from December 2004 through January 2005. The instrument used in this study was the elderly dependence scale developed by the Park (2004). Collected data were analyzed using SPSS 11.0 for Windows. Descriptive statistics, independent t-test, ANOVA and multiple regression were done. Results: In the results of regression, residence, education, vision and age were extracted as factors influencing the dependence of the elderly. The regression model explained 33% of the variance. Conclusion: Considering the results above, we need studies on the dependence of the elderly using more independent variables, on the changing pattern of dependence and influencing factors by longitudinal design, and on the elderly with functional limitations or cognitive impairment.

  • The elderly population of Korea has been significantly increasing due to advances in public health, medical care, and quality of life. Social, economical influence of the elderly population has been increasing, too. Research regarding elderly people is important because many elderly people take care of their appearance and clothing, and clothing plays an important role in the elderly women's everyday life. This study investigated the life satisfaction, appearance satisfaction, and clothing behavior of women aged 55 years and older who were residents of Seoul. The results of this study are as followings: 1. The importance of various factors on clothing behavior is different. They are management, clothing importance, fashion indifference, information search and purchase planning, clothing dependence, status symbol, and conformity in order of the importance. 2. Age has a positive relationship with each of fashion indifference and clothing dependence, but a negative relationship with information search and purchase planning. 3. Age has a positive relationship with each of life satisfaction and allowance. 4. Appearance satisfaction is positively related with age, but is significantly related with neither allowance nor education. 5. There are positive relationships between life satisfaction and all clothing behavior factors except status symbol. 6. Appearance satisfaction are siginicantly correlated with management, conformity, clothing dependence, and clothing importance. And life satisfaction has more significant relationship with clothing behavior than appearance satisfaction does.
