Background: Hardcore smoking is represented by a subset of daily smokers with high nicotine dependence, inability to quit and unwillingness to quit. Estimating the related burden could help us in identifying a high risk population prone to tobacco induced diseases and improve cessation planning for them. This study assessed the prevalence and associated factors of hardcore smoking in three South-East Asian countries and discussed its implication for smoking cessation intervention in this region. Materials and Methods: Global Adult Tobacco Survey (GATS) data of India, Bangladesh and Thailand were analyzed to quantify the hardcore smoking prevalence in the region. On the basis of review, an operational definition of hardcore smoking was adopted that includes (1) current daily smoker, (2) no quit attempt in the past 12 months of survey or last quit attempt of less than 24 hours duration, (3) no intention to quit in next 12 months or not interested in quitting, (4) time to first smoke within 30 minutes of waking up, and (5) knowledge of smoking hazards. Logistic regression analysis was carried out using hardcore smoking status as response variable and gender, type of residence, occupation, education, wealth index and age-group as possible predictors. Results: There were 31.3 million hardcore smokers in the three Asian countries. The adult prevalence of hardcore smoking in these countries ranges between 3.1% in India to 6% in Thailand. These hardcore smokers constitute 18.3-29.7% of daily smokers. The logistic regression model indicated that age, gender, occupation and wealth index are the major predictors of hardcore smoking with varied influence across countries. Conclusions: Presence of a higher number of hardcore smoking populations in Asia is a major public health challenge for tobacco control and cancer prevention. There is need of intensive cessation interventions with due consideration of contextual predictors.

The purpose of this study was to identify the difference of school food service dietitians' work value, job satisfaction, and turnover intention based on their expectation to be a nutrition teacher. Also, this study explored the differences in expectation to be a nutrition teacher, work value, job satisfaction, turnover intention depending on demographics and school foodservice operational characteristics. This study surveyed dietitians who worked at school foodservice in Kyunggii and Daegu Gyeoungbuk Province. A total of 509 responses were collected using on-site survey and online survey (59.3%). Dietitians expressed favorable work value ($3.88{\pm}0.34$) and mid level of a job satisfaction ($2.99{\pm}0.64$). The percentage of dietitians who had an intention to leave after the promulgation of a nutrition teacher system (13.2%) was lower than that of dietitians who had an intention to leave prior to it (23.2%). Most dietitians expected a salary rise (84.7%), more chance to teach nutrition education (76.0%), and the improvement of power not only as a teacher but as a dietitian (72.7%). Dietitians who had higher expectation levels to be a nutrition teacher (> 3 on the 5 point Likert scale) showed a higher tendency of significant turnover intention (F = 4.40, p < 0.01) and more confident work value (F = 15.292, p < 0.001) when comparing those who had lower expectations. There were significant differences in work value, job satisfaction, turnover intention, and expectation to be a nutrition teacher depending on career length and employment status of dietitians. This study revealed that school food service dietitians have favorable expectations to be nutrition teachers with high work value.

Ubiquitous is a Latin-derived word meaning "to exist at any time and place" like water or air. In computing, the word "ubiquitous" indicates an environment in which users have access to networks without any limitation regarding computer networks or places. Important issues in building Ubiquitous Korea (U-Korea) are the social problems appearing with a rapid increase in the old age population. Nowadays, with the rise of the nuclear family, the increase in the number of elderly people living alone, and the change in the status of women, both wives and husbands are employed outside the home, and the relatives who would be responsible for supporting the elderly sometimes are on long or short business trips, and it happens that old people can't be looked after. Therefore the government developed a wireless paging system for the sick, disabled, old and weak so that when an emergency happens, by just simply dialing 119, an emergency aid center could take prompt action. However, the present wireless paging systems composing the under-layer of the emergency aid information system have some problems, such as, a lack of reliability, problems among terminals, mobile transmitters and receiving terminals, the users' refusal to admit the need for the system and poor operational skills, administrators' perfunctory management and checks, etc. On account of these problems, the system efficiency has degraded and therefore a system upgrade is necessary. In this paper, we attempt to evaluate the newly implemented SAFE119 system, a new wireless paging system seeking to correct the problems of the current system.

Objectives : This study aims to analyze the tasks, recognition and obstacles in operation of school dental clinics and to examine opinions on installation, operation and prerequisites for toothbrushing facilities. Methods : It conducted a survey t o the persons in charge at 378 school dental clinics in Korea and total 127 sheets, excluding incompletely answered data, were used for analysis by using SPSS 18.0. Results : Two regular dental hygienists visit school dental clinics 2-3 times per week and work 4-6 hours per week on average. Their tasks include oral health education, toothbrushing instruction, oral examination, sending school newsletters, and dental sealants. The obstacles of operation include excessive workload other than the work for the school dental clinic, lack of dentists, and lack of cooperation of principals and teachers in school. The persons in charge think that the chief task of the school dental clinic is the continuous oral health management, and it effectively affects students' oral health improvement. Most of them were for the installation of toothbrushing facilities. They said that it will be effective in students having an adequate toothbrushing habit and their toothbrushing rate increasing higher. They thought that if the school dental clinic is changed to toothbrushing facilities, it will improve students' oral health management. The prerequisites for toothbrushing facilities are the support of manpower in charge, principal's support, and development of operational programs. Conclusions : The most effective function of school dental clinics is constant oral health management. However, when public health doctors are reduced and dental sealants get included in health insurance, the budget of local government will decrease and then it will eventually reduce the work of school dental clinics. Therefore, it is needed to enhance support for school dental clinics or install a toothbrushing facilities rather than a school dental clinic.
