This study is to define the caring experience of mothers with insulin-dependent diabetes mellitus children, by finding core category, contextual factors, ntervening factors, and the patterns of caring, and to velop a practice theory on it. Research method followed grounded theory methodology by Strauss & Corbin. Subjects were six mothers. whose children have had insulin-dependent diabetes mellitus for 4 months to 14 years by the interview time. They were selected by theoretical sampling. Data were collected from September, 1995 to January, 1996. Interview were done by long interview technique and observation. Each interview took 50 minutes to 2 hours. Content of interview was recorded and transcribed later. Based on the results of previous interview, content of next interview was planned until data reached to the saturation point. Results were as follows : One hundred and forty concepts were found. These concepts were grouped into thirty-three categories, and then to ten categories. Mothers with diabetic child were revealed to face “being overwhelmed by burden”. Overwhelming by burden is found to be progressed through the cycle production-coping-decrease or in crease process. Mothers showed four patterns of adaptation in caring the diabetic children. 1) If mothers felt large amount of overwhelming by burden because of difficulty of caring and unsympathizing but they had sufficient support, no condition of the child, and their coping mechanism was positive, most of them overcome with strong will, but some fell into burnout. 2) If mothers felt large amount of overwhelming by burden because of difficulty of caring, unsympathizing, insufficient support. serious condition of the child, and their coping mechanism was negative, they fell into burnout by coping with feeling. 3) If mothers felt small amount of overwhelming by burden because of little difficulty of caring and sympathizing, sufficient support. no serious condition of the child, but their coping was negative, most of them fell into burnout by coping with feeling, but some overcome. 4) If mothers felt small amount of overwhelming by burden because of little difficulty of caring and unsympathizing, sufficient support, no serious condition of the child, and their coping was positive, they overcome with strong will. On the basis of the above result, in order to help mothers take good care of their children, nursing assesment and intervention on life readjustment, and getting support should be required. Especially, through understanding mothers' personalities, individual support consistent with each of them should be required. Therefore education. counseling, mutual support and exchange of information will have to be accomplished.

Objectives: Ischemic heart disease (IHD) is a major cause of death in Korea and known to result from several occupational factors. This study attempted to estimate the current magnitude of IHD mortality due to occupational factors in Korea. Methods: After selecting occupational risk factors by literature investigation, we calculated attributable fractions (AFs) from relative risks and exposure data for each factor. Relative risks were estimated using meta-analysis based on published research. Exposure data were collected from the 2006 Survey of Korean Working Conditions. Finally, we estimated 2006 occupation-related IHD mortality. Results: For the factors considered, we estimated the following relative risks: noise 1.06, environmental tobacco smoke 1.19 (men) and 1.22 (women), shift work 1.12, and low job control 1.15 (men) and 1.08 (women). Combined AFs of those factors in the IHD were estimated at 9.29% (0.3-18.51%) in men and 5.78% (-7.05-19.15%) in women. Based on these fractions, Korea's 2006 death toll from occupational IHD between the age of 15 and 69 was calculated at 353 in men (total 3,804) and 72 in women (total 1,246). Conclusion: We estimated occupational IHD mortality of Korea with updated data and more relevant evidence. Despite the efforts to obtain reliable estimates, there were many assumptions and limitations that must be overcome. Future research based on more precise design and reliable evidence is required for more accurate estimates.

This study aimed to examine factors and the correlations of burnout and job satisfaction in hospital dietitians. Burnout was classified into three sub-concepts: emotional exhaustion, depersonalization, and reduced personal accomplishment. Job satisfaction was also classified into three sub-concepts, including relationships, self-realization, and advancement opportunities. A survey was conducted with dietitians working in general hospitals of over 400 beds, in the Seoul metropolitan area. The factors that significantly influenced emotional exhaustion were health, work hours, number of intern dietitians, self-esteem, level of responsibility, while the factors that influenced depersonalization were relationships with coworkers, and role ambiguity. Personal accomplishment was influenced by age, the number of staff dietitians, the general number of managed workers, and self-esteem. In terms of job satisfaction, relationship was affected by age and relationships with supervisors, while self-realization was influenced by work hours, health, the number of patient meals, and role ambiguity. Age, job regularity, business management, role ambiguity, and relationships with supervisors also affected advancement opportunities. Emotional exhaustion, depersonalization, and reduced personal accomplishments, which represented burnout, had negative relationships with satisfaction with relationships, self-realization and advancement opportunities. Dietitians with low job satisfaction were likely to experience burnout. These results suggest that burnout and job satisfaction are influenced by internal and external factors that are individual or organizational problems encountered by hospital dietitians. Therefore, managers as well as dietitians need to understand these factors and overcome them through communication and mutual support.

The purpose of this study is to compare calculated pollutant loadings using pollutant load unit factors and vector type coverage, and expected mean concentration(EMC) and raster type of digital elevation model(DEM). This study is also focusing on comparison of the advantages and the disadvantages of the two methods, and seeking for a method of calculation of pollutant loadings using DEM. Estimation of pollutant inputs using pollutant load unit factors has limitations in identifying seasonal variations of pollutant loadings. Seasonal changes of runoffs should be considered in the calculation of pollutant loadings from catchments into reservoirs. Evaluation of pollutant inputs using runoff-coefficient and EMC can overcome these drawbacks. Proper EMC and runoff-coefficient values for the Koeup stream catchments of the Koheung estuarine lake were drawn from review of related papers. Arc/Info was employed to establish database of spatial and attribute data of point and non-point pollutant sources and characteristics of the catchments. ArcView was used to calculate point and non-point pollutant loadings. Pollutant loads estimated with either unit factors-coverages, i.e., pollutant load unit factors and vector coverages f point sources and land use, or EMC and digital elevation mode(DEM) were compared with stream monitoring loads. We have found that some differences were shown between monitoring results and estimated loads by Unit Factors-Coverage and EMC-DEM. Monthly variations of pollutant loads evaluated with EMC-DEM were similar to those with monitoring result. The method using EMC-DEM can calculate accumulated flows and pollutant loads and can be utilized to identify stream networks. A future research on correcting the difference between vector type stream using flow direction grid and digitalizing vector type should be conducted in order to obtain more exact calculation of pollutant loadings.

Bodyguards always perform their duty with psychological burdens in their mind, not only because security situations are developed in various forms dependent on the surrounding environments or circumstances, but because bodyguards only take follow-up actions while the criminal decides time, place, and style of every attack. Thus, in the security situation, it is not uncommon for bodyguards to experience muscle rigidity, uncontrollable emotional elevation, difficulty in concentration, negative perception, frustration and enervation, which are caused by continuous physical/mental burdens, stimulations by various interpersonal behaviors or minute environmental stimulants. In conclusion, the result of performing security duties is related in the first place with the degree of the bodyguard's potential, in the second place with the degree of training and efficiency. And the result can also be changed by the way they control their negative psychological state of the moment when they carry out the skills they acquired. Maximizing the performance of the bodyguards by helping them overcome these psychological factors may be facilitated by detecting their psychological factors, understanding the causes, and training them in applying appropriate measures for overcoming these factors. When these measures are applied, the positive perception is indispensable that duties of protecting clients can be carried out successfully. No single measure can be declared to be more effective than the other because the effect of each measure is expressed differently by the individual characteristics of the bodyguards. However, it is important to select and apply the measures most appropriate to the bodyguard. Besides, they should devote themselves to the training with persistence because efficient implement of the measures for overcoming psychological factors takes a lot of time.

The aim of this study was to clarify the barriers of dental treatment for special needs patients felt by dentists and to determine the dentist-related factors contributing to the obstacles in treatment planning and decision making. Questionnaires were distributed and responded by dentists working at five public-based special care clinics in South Korea. Factors divided into three parts (dentist demographics, clinical factors, and educational and administrational factors) were assessed and analyzed for correlations between dentist-related factors and dentist-felt burdens for special care treatment. Fisher's exact test and Chi-square test were used at the level of 0.05. A total of 34 dentists responded to the questionnaires. Almost all dentists had obstacles in the treatment of special needs patients in terms of the patients' lack of cooperation (94.1%), proxy communication with caregivers (94.1%), payment reward system (63.6%), deficient workforce (67.7%), and others. The longer dentists had been practicing for special needs patients, the more they were dissatisfied with the reward system and a longer time was spent for communication with patients and their caregivers (p<0.05). For specialists, more obstacles were experienced in treatment planning due to a deficiency in the clinical information obtained from their patients compared to general practitioners (p<0.05). A total of 82.4% of the respondents approved of mandatory educational programs for special care dentists. There were practitioner-based factors related to the amount of obstacles felt by special care dentists. To overcome the treatment barrier of special needs patients, in-depth education and training are required in special care dentistry.

Opisthorchis viverrini is an ongoing public health problem in Northeast Thailand. Despite continuous efforts for decades by healthcare organizations to overcome this problem, infection rates remain high. To enable related personnel to identify and address the various issues effectively, a cross-sectional study was performed to investigate prevalence and risk factors for opisthorchiasis. The target group was 3,916 Thai residents of Northeast Thailand who were 15 or over. Participants were recruited using the 30 clusters sampling technique. The data were gathered through questionnaires, focus group discussions, in-depth interviews, and stool examinations for parasite eggs (using the Modified Kato Katz method). The data were analyzed using descriptive and inference statistics; in order to ascertain the risk factors and test them using the odds ratio and multiple logistic regressions. The prevalence of opisthorchiasis was 22.7% (95%CI: 0.26 to 0.24). The province with the highest prevalence was Nakhorn Phanom (40.9%; female to male ratio =1:1.2). The age group with the highest prevalence was 40-49 year olds. All age groups had a prevalence >20%. Four of seven provinces had a prevalence >20%. The factors related to opisthorchiasis were (a) sex, (b) age (especially > 50), (c) proximity and duration living near a water body, and (d) eating raw and/or fermented fish. In order to reduce the prevalence of opisthorchiasis, the focus in populations living in upper Northeast Thailand should be changing their eating behaviors as appropriate to their tradition and context.
