        Efficiency and Productivity Impacts of Restructuring the Korean Electricity Generation

        Almas Heshmati 한국경제연구학회 2013 Korea and the World Economy Vol.14 No.1

        This paper investigates the performance of various generation plants in the Korean electricity market. The objective is to compare performance before and after the 2001 separation by using data from 1995 to 2006. The efficiency and productivity of the generation units is estimated by using a stochastic frontier model as well as data envelopment analysis and Malmquist productivity index. The result suggests that generation is mainly affected by facility type, maintenance cost, real fuel cost, and other costs. The national generation plan is characterized by high efficiency of nuclear plants, base type facilities, and large size facilities. It is also found that efficiency enhancement from the separation effect is not clearly discernible when comparing periods before and after the separation. Suggestions are made for the better utilization of economies of scale to further raise the efficiency of generation companies and the electricity industry through enhancement of fuel purchasing power and reallocation of labour.

        Insights into the state of radiation protection among a subpopulation of Indian dental practitioners

        Almas Binnal,Gururaghavendran Rajesh,Ceena Denny,Junaid Ahmed,Vijayendra Nayak 대한영상치의학회 2013 Imaging Science in Dentistry Vol.43 No.4

        Purpose: Radiographs is an integral part of patient management in dentistry, despite their detrimental effects. As the literature pertaining to radiation protection among Indian dental practitioners is sparse, exploring such protection is needed. Materials and Methods: All private dental practitioners in Mangalore, India were included in the study. A structured, pre-tested, self-administered questionnaire was employed to assess the knowledge, attitudes, practices, previous training, perceptions towards the need to spread awareness, and willingness to gain and implement knowledge about radiation hazards and protection. Information regarding each respondent’s age, gender, education, and type and duration of practice was collected. Results: Overall, 87 out of 120 practitioners participated in the study. The mean knowledge, attitude, and practice scores were 9.54±2.54, 59.39±7.01, and 5.80±3.19, respectively. Overall, 25.3% of the respondents had undergone training in radiation protection, 98.9% perceived a need to spread awareness, and 94.3% were willing to improve their knowledge. Previous training showed a significant correlation with age, sex, and duration of practice; attitude was significantly correlated with education and type of practice; and knowledge scores showed a significant correlation with type of practice. Conclusion: Although the knowledge and practices of respondents were poor, they had a positive attitude and were willing to improve their knowledge. Age, sex, and duration of practice were associated with previous training; education and type of practice with attitude scores; and type of practice with knowledge scores. The findings of this study suggest a policy is needed to ensure the adherence of dental practitioners to radiation protection guidelines.

        An Econometric Model of Employment in Zimbabwe's Manufacturing Industries

        Almas Heshmati,Mkhululi Ncube 중앙대학교 경제연구소 2004 Journal of Economic Development Vol.29 No.2

        This paper is concerned with the estimation of employment relationship and employment efficiency under production risk using a panel of Zimbabwe’s manufacturing industries. A flexible labour demand function is used consisting of two parts: the traditional labour demand function and labour demand variance function. Labour demand is a function of wages, output, quasi-fixed inputs and time variables. The variance function is a function of the determinants of labour demand and a number of production and policy characteristic variables. Estimation of industry and time-varying employment efficiency is also considered. The empirical results show that the average employment efficiency is 92%.

        Background: Initiation, perpetuation and cessation of smoking are all multifactorial. It is essential to explore interactions among various parameters influencing smoking and its cessation for effective smoking cessation interventions. Objectives: To obtain insights into smoking and its cessation among current smokers in India. Materials and Methods: The present study was conducted among current smokers visiting the Department of Oral Medicine and Radiology, Manipal College of Dental Sciences (MCODS), Manipal University, Mangalore. Knowledge, attitudes, behavior, worksite practices towards smoking and its cessation, barriers to smoking cessation and socio-demographic variables were explored using a structured, pretested, self-administered questionnaire. Results: A total of 175 current smokers participated in the study. Mean knowledge, attitude, worksite practice and barrier scores were $15.2{\pm}5.67$ (66.1%), $57.5{\pm}7.67$ (82.1%), $4.18{\pm}2.02$ (41.8%) and $57.4{\pm}12.37$ (63.7%) respectively. Correlation analysis revealed: association of knowledge with education, occupation and religion; attitude with education and occupation; worksite practices with occupation; knowledge with attitude; and barriers negatively with worksite practices. The majority (85.7%) of respondents intended to quit smoking and this was associated with higher attitude scores, whereas actual quit attempts were associated with high knowledge, attitudes, worksite practices and low barrier scores. Conclusions: Various socio-demographic factors associated with smoking and its cessation were identified. The present study highlights the importance of identifying and targeting these interactions while framing guidelines and interventions for effective tobacco cessation in a developing country like India.
