This study was intended to enhance the level of hospital personnel management through analysing job satisfaction of hospital employees in terms of structural, personal and environmental variables. The sample of this study consist of a total of 790 persons including doctors, residents, interns, pharmacists, nurses, medical engineers, office workers and manual workers who have worked for general hospitals with 200 beds, 300 beds and 800 beds respectively. The Likert's 5 scales were used for the measurement of satisfaction. The results can be summarized as follows: 1. Structural Variables The level of satisfaction on the job itself was generally low, 2.8 in Likert's 5 scales, with the order of role ambiguity(3.87), routinization(2.6), work overload (2.45) and autonomy(2.37). Hospital employees are aware of their responsibility and they regarded their work as heavy one. The compensatory satisfaction degree was 2.5 which was also low: There were in the order stability(3.1), distributive justice(2.57), pay(2.3) and promotion(1.9). Usually hospital employees showed high degree of stability, while, their satisfaction on promotion possibility is quite low due to specially differentiated structures of hospitals. The degree of satisfaction on the internal conditions of organizational culture was relatively higher as 2.92: They were co-worker's support(3.69), supervisory support(3.15), role conflict(2.64) and welfare(2.17) in order. The satisfaction on welfare as an economic condition was the lowest. 2. Personal Variables The level of satisfaction on personal variables was 3.27 which seemed to be quite high: Contribution to the hospital(3.38), attitude on job performance(3.28) and pride as a member of the hospital(3.07). They seem to believe that their work has been helpful to the performance of hospitals. 3. Environmental Variables The degree of satisfaction on these variables was 3.07 on the average which was derived from environmental factors such as family-role conflict and community support related to hospital employees' environment. The order of satisfaction for each variable is community support(3.2) and family-role conflict(2.94). They turned out to be fairly satisfied with their job in community and yet, they wanted more spare time to spend with their family.

This study was focused on figure out what kinds of elements are influencing on job satisfaction with approach of the educational system. It was also to figure out how work characteristics and role conflicts of employees influence on job satisfaction. Objects of study were employeeswho had been working in Hospice and Palliative medical center at least for 6 months, and they were doctors, nurses, ministers, and welfare workers. Collected materials were analyzed by Frequency Analysis, One-way ANOVA, Correlation Analysis, and SimpleRegression Analysis. Results from study can be summarized like below. The first, job satisfaction of workers in Hospice and Palliative medical center were 3.36, and this numerical value is pretty high over all. For saying from the higher to the lower satisfaction level, there were satisfaction with job itself, satisfaction with co-workers, satisfaction with seniors (superiors), and satisfaction with organizations, on the other hands, satisfaction with salaries was turned out as the lowest level among those. The second, role conflict was 2.63, and it is considered as the medium level. after inquiring into it by elements of role conflict, they felt many environmental difficulties compared to other workers in different fields such as environmental difficulty, role ambiguity, insufficient ability, process obscurity, etc. The third, work environment influencing on job satisfaction are as follows. Professional environment among characteristics of work environment was significant statistically. Job satisfaction of ministers was the highest; others were in the order of doctors, welfare workers, and nurses. For employment history, job satisfaction was higher as they have more and longer job experience including whole professional experience both in hospice and palliative medical center. In addition, participating in hospice and palliative programs, intensive training regularly was significantly. Job Motivation was also significant statistically. Especially, job satisfaction was higher when people decided to work in hospice and palliative medical center because of individual desire (self-realization). Lastly, influence of role conflict on job satisfaction is as follows. Environmental difficulty, role ambiguity, insufficient ability, process obscurity, etc showed the significant meaning statistically, and the lower role conflict was related with the higher job satisfaction. Suggestions for next study based on such results are as follows in order to improve or increase job satisfaction of employees in hospice/palliative medical centers. The first, to expand education opportunity of employees is needed to increase job satisfactionof hospice/palliatives medical centers. Participating in intensive programs and seminars by types of occupation and acquiring professional knowledge are very important since employees are motivated by those activities. For that, developing and activating intensive education/programs by professional occupations are suggested. The second, dividing roles of employees and determining each job's limit clearly in hospice/palliative medical centers are required. For that, study developing standard job regulations is suggested for each professional job. Lastly, developing and providing reasonable salaries is needed because low salaries of hospice/palliative medical centers are the absolute reason lowering job satisfaction. Therefore, this paper suggests improving the salary level of employees of hospice/palliative medical centers and developing practical plan for it.

This study was performed to investigate laboratory workers' exposures to airborne nanoparticles at a university laboratory where acid treatment experiments were conducted on the surfaces of engineered carbon nanotubes (CNTs). The surface area concentrations, number concentrations, and mass concentrations of airborne nanoparticles were measured at personal breathing zones (PBZs) for various tasks using direct reading instruments. For all three metrics, airborne nanoparticle concentrations during the experiments were higher than background levels measured before and after the experiments for all three metrics. Among the various tasks that were performed as part of these experiments, one task that involved filtering a mixture of acid and CNTs showed the highest concentrations in all three metrics, with concentrations of $116.6\;{\mu}m^2$/cc, 24320 pt/cc, and $9.0\;{\mu}g/m^3$, respectively. Nanoparticle surface area concentrations measured at a representative area fluctuated with those at the PBZs in the laboratory. This result indicates that nanoparticles generated during the experiments were not just limited to the PBZs of the workers but were also present throughout the room, potentially exposing co-located workers. CNTs were detected by a transmission electron microscope in an air sample collected while handling the CNTs. All the tasks were performed inside fume hoods, with the sliding sashes open to their required heights. It was noted that the capture velocities of the fume hoods were much lower than the American National Standards Institute (ANSI)'s recommendation level (0.4 to 0.6 m/s). In conclusion, this study showed that, due to inadequate control, laboratory researchers performing acid treatment experiments on surfaces of CNTs were exposed to airborne nanoparticles generated during the tasks.

Recent livestock people concern not only increase of production, but also superior quality of animal-breeding environment. So far, the optimization of the breeding and air environment has been focused on the production increase. In the very near future, the optimization will be emphasized on the environment for the animal welfare and health. Especially, cattle farming demands the precision livestock farming and special attention has to be given to the management of feeding, animal health and fertility. The management of individual animal is the first step for precision livestock farming and animal welfare, and recognizing each individual is important for that. Though electronic identification of a cattle such as RFID(Radio Frequency Identification) has many advantages, RFID implementations practically involve several problems such as the reading speed and distance. In that sense, computer vision might be more effective than RFID for the identification of an individual animal. The researches on the identification of cattle via image processing were mostly performed with the cows having black-white patterns of the Holstein. But, the native Korean and Japanese cattle do not have any definite pattern on the body. The purpose of this research is to identify the Japanese black cattle that does not have a body pattern using computer vision technology and neural network algorithm. Twelve heads of Japanese black cattle have been tested to verify the proposed scheme. The values of input parameters were specified and then computed using the face images of cattle. The images of cattle faces were trained using associate neural network algorithm, and the algorithm was verified by the face images that were transformed using brightness, distortion, and noise factors. As a result, there was difference due to transform ratio of the brightness, distortion, and noise. And, the proposed algorithm could identify 100% in the range from -3 to +3 degrees of the brightness, from -2 to +4 degrees of the distortion, and from 0% to 60% of the noise transformed images. It is concluded that our system can not be applied in real time recognition of the moving cows, but can be used for the cattle being at a standstill.

458 female workers working in the small and medium scaled industries in Inchon area were surveyed to study their general characteristics, health behavior, working and environmental conditions, awareness of exposure at hazardous materials, current health status, and degree of working satisfaction. Self-administered questionnaire was distributed to the female workers with the explanation by trained interviewer on the purpose of survey and the method how to answer. The results were as follows : (1) 75.5% of the respondents are living with their families and others are living in domitary or rent house for herself. Age distribution ranges from teenagers to warren in their forties. In marital status 69.0% of workers are single and 31.0% of them have ever married. 69.4% of workers are high school graduate. The size of factory is 48.3% with less than 300 workers, 42.1% with 300~500 workers. (2) Most of the workers(86.7%) are full time workers, 52% of the respondents have working experiences in other factories. More than 65% have fewer than 5 years working experience. (3) The awareness of exposure at noise was 33% of respondents, it was significantly different by skilled status. The awareness of exposure at dust, other hazardous material was each 13.3%, 12.4% of respondents. (4) 26% of them are unsatisfied with their working cognitions and 43.7% of them are unsatisfied with their welfare in occupational system unsatisfactory rate of promotion is higher in the unmarried workers(45.6%), skilled workers(47.2%), full time workers(47.4%), long term workers(50%), and awareness group of exposure hazardous material(51.3%), compared to married women workers, unskilled workers, part-time workers, short term workers and unawareness group of exposure at hazardous materials. (5) The index of working satisfaction is rated on a scale of 1 to 10 with the higher point indicating higher satisfaction. Among the selected variables, marital status, working status, the awareness of exposure at hazardous materials, were statistically significant with the index of working satisfaction. (6) By multiple regression analysis showed that the determinant factors of index of working condition were health index, the awareness of exposure at dust, the awareness of exposure other hazardous materials, marital status and working period. In conclusion, there is a significant relationship between the awareness of exposure at hazardous material the index of working satisfaction. Therefore if the workers are less exposed to the hazardous material and are educated properly they will be more satisfied with their work thus improving their health and productivity. Finally, with the result of this study, there is a great need for the development of a health promotion program and a welfare policy for small-scale factories.

Objectives: Lung cancer is a major public health problem and one of the most costly illnesses. The study aimed to estimate the economic burden of lung cancer in Iran in 2014. Methods: A cross-sectional study was conducted to estimate the direct and indirect costs for patients with lung cancer using a prevalence-based approach. A human capital approach was employed to estimate the indirect costs. Data were obtained from several sources such as through patient interview using structured questionnaire, medical records, the GLOBOCAN databases, the Iranian Statistical Center, the Iranian Ministry of Cooperation, Labor and Social Welfare, and the Institute for Health Metrics and Evaluation (IHME). Results: The economic burden of lung cancer in Iran in the year 2014 was 3,225,998,555,090 IR. The main components of the cost were associated with mortality (81.9 %) and hospitalization (7.6 %). The costs of direct medical care, non-medical aspects, patient time, and mortality accounted for 10.8%, 2.7%, 4.5%, and 81.5% of the total cost, respectively. Conclusion: Findings from this study indicated that the economic burden of lung cancer is substantial both to Iran's health system and to society as a whole. Early diagnosis, strengthening cancer prevention, implementing new cancer therapy and medical technology, and effective smoking-cessation interventions could offset some of the costs associated with lung cancer in Iran.

The purpose of this study was to explore the concepts of health among people with mobility disabilities in order to develop a new holistic model of health and to identify implications for social work practice. A qualitative study based on face-to-face interviews with people with mobility disabilities was conducted. Nine consumers and nine social workers with mobility disabilities participated in the study. Social constructionism, heuristic paradigm, empowerment paradigm, and strength perspectives were used to form conceptual foundations to guide the study. Study participants' holistic descriptions of the concept of health encompassed five domains: biological/physical, mental/emotional, financial, relationships with others, and spiritual. Participants described health as harmony among these five domains. Harmony indicates that all five domains contribute to the concept of health, and that each domain is related to the others. Participants also viewed disability and health as an interconnected whole, not separate concept. The conceptual model developed in this study expands on the existing concepts of health by considering multiple factors at the personal and environmental levels, as well as interactions among the factors and between the levels. The personal level has five domains: biological/physical, mental/emotional, spiritual, financial, and relationships with others. The environmental level has also five domains: relationship with others, financial, social programs, social attitudes toward peoplewith disabilities, and physical environment. All factors under the personal and environmental levels also affect each other. The holistic concept of health for people with disabilities is not solely a part of the person, but rather is a function of the interaction between the person and their environment. The study demonstrated that people with disabilities have strength and resiliency, and health is an attainable goal for them, particularly when environmental and cultural barriers are addressed. The focus of social work practice should be the removal of those barriers encountered by their consumers with disabilities, as well as, the enhancement of internal factors that facilitate well-being.
