The purpose of this study was to analysis level on family caregiver's burden for the elderly with senile dementia in a rural area and to choose priority care group, thereby facilitating the development of interventions to reduce the caregiver's burden. For this purpose, data were collected by questionaire from June 10 to October 8, 1994. The instruments for data collection were Caregiver Burden Inventory by Novak(1989) and Zarit et al(1982), severity of dementia by Hughes Scales (1982), ADL by Lawton (1971), patients' family caregiving activity by pre-survey and reference review(Lee, 1993 ; Jang, 1990 ; Yoo, 1982). The subjects were 60 family caregiver of senile dementia in a rural area. The data was analysed by the use of t-test, ANOVA, correlation and multiple regression. The results were as follows : 1. Total burden was evaluated over average, the mean of family burden was 61.24. 2. Significant variables which were correlated to the family caregiver's burden were the severity of dementia(F=30.52, p<0.001), ADL(F=5.43, p<0.01), PADL(F=6.14, p<0.01), caregiver's health status(F=6.05, p<0.01), a view of patient's prognosis(F=4.08, p<0.05), the number of hours per day spent on caregiving(F=19.64, p<0.001), level of intimacy of caregiver and patients(F=7.16, p<0.001), the frequency of caregiving activity(F=5.31, p<0.01). 3. ADL was the most important predictor to family caregiver burden(R2=0.6611). In addition to this, the severity of dementia, level of intimacy of caregiver and patient, relationship with the patient accounted for 79% of family caregiver burden. 4. The criteria of priority care group were as follows ; the mean of family caregiver burden was above 58, above of moderate ADL, the number of hours per day spent on caregiving above of 8 hours, above of moderate dementia. By the the severity of dementia, number of priority care group, mild dementia was 10(43.4%), moderate dementia 23 (92.0%), sever dementia 12(100.0%).

Background: Job stress and job satisfaction are important factors affecting workforce productivity. This study was carried out to investigate the job stress, job satisfaction, and workforce productivity levels, to examine the effects of job stress and job satisfaction on workforce productivity, and to identify factors associated with productivity decrement among employees of an Iranian petrochemical industry. Methods: In this study, 125 randomly selected employees of an Iranian petrochemical company participated. The data were collected using the demographic questionnaire, Osipow occupational stress questionnaire to investigate the level of job stress, Job Descriptive Index to examine job satisfaction, and Hersey and Goldsmith questionnaire to investigate productivity in the study population. Results: The levels of employees' perceived job stress and job satisfaction were moderate-high and moderate, respectively. Also, their productivity was evaluated as moderate. Although the relationship between job stress and productivity indices was not statistically significant, the positive correlation between job satisfaction and productivity indices was statistically significant. The regression modeling demonstrated that productivity was significantly associated with shift schedule, the second and the third dimensions of job stress (role insufficiency and role ambiguity), and the second dimension of job satisfaction (supervision). Conclusion: Corrective measures are necessary to improve the shift work system. "Role insufficiency" and "role ambiguity" should be improved and supervisor support must be increased to reduce job stress and increase job satisfaction and productivity.

Background: Inflammatory diseases can increase the prevalence of anemia. Recent studies confirmed that the prevalence of anemia is increased by atopic dermatitis (AD), a chronic inflammatory disease. Therefore, we aimed to elucidate the correlation between AD severity and prevalence of anemia. Methods: We used data of pediatric patients from the Health Insurance Review and Assessment Service (HIRA-PPS-2016). We included pediatric patients (<18 years) with AD diagnosis who were prescribed medications for AD. We applied a propensity score method with inverse probability of treatment weighting (IPTW) adjusting for differences in prevalence of confounders and performed IPTW logistic regression to evaluate associations between the anemia and severity of AD. Results: In total, 91,501 patients (mild AD: 47,054 patients; moderate-to-severe AD: 44,447 patients) <18 years who were prescribed drugs for AD were analyzed. Analysis of the probability of patients with mild AD and prevalence of anemia as a reference revealed an odds ratio (OR) of 1.159 (95% CI, 1.109-1.212; p<0.001) in moderate-to-severe AD patients, indicating a correlation between anemia prevalence and AD severity. Subgroup analysis according to gender, age group, and type of health insurance revealed there was an association between AD severity and anemia except in patients equal or older than 7 years. Conclusion: The prevalence of anemia increased with AD severity despite adjusting for confounding factors. Our results support the hypothesis that AD can cause anemia, and anemia prevalence could be increased in severe AD patients. Further studies are needed to establish a pathological basis.

Background: Food insecurity may contribute to mental health indicators such as stress, anxiety, or depression. We investigated whether food insecurity was associated with mental health indicators and health-related quality of life (HRQoL) in a representative sample of the Korean population. Methods: This study enrolled 12,987 adults without a history of medically serious disease from the 2012, 2013, and 2015 Korea National Health and Nutrition Examination Survey. Household food security status was categorized as "food security," "mild food insecurity," and "moderate/severe food insecurity." The association between mental health and HRQoL was evaluated using a multivariate logistic regression model with food security as the reference group. Results: The adjusted odds ratio of adverse mental health or low HRQoL increased significantly in mild or moderate/severe food insecurity compared to food security. In the moderate/severe food insecurity group, it was 1.98% (95% confidence interval [CI], 1.31-2.99) higher for perceived stress, 3.58% (95% CI, 2.44-5.26) higher for depression symptoms, 4.16% (95% CI, 2.68-6.45) higher for suicidal ideation, and 2.81% (95% CI, 1.91-4.15) higher for quality of life. Conclusion: Food insecurity was strongly associated with negative mental health status and poor HRQoL. There is a need for a dietary support program that provides psychosocial support to those experiencing food insecurity.

Background: In workers with moderate to severe work-related traumatic brain injury (wrTBI), this study aimed to investigate the effect of the timing of rehabilitation therapy initiation on the length of hospital stay and the factors that can influence this timing. Methods: We used data obtained from the Republic of Korea's nationwide Workers' Compensation Insurance. In the Republic of Korea, between the years 2010 and 2019, a total of 26,324 workers filed a claim for compensation for moderate to severe wrTBI. Multiple regression modeling was performed to compare the length of hospital stay according to the timing of rehabilitation therapy initiation following wrTBI. According to the timing of the initiation of rehabilitation therapy following TBI, the proportions of healthcare institutions that provided medical care during each admission step were compared. Results: The length of hospital stay for workers who started rehabilitation therapy within 90 days was significantly shorter than that for workers who started rehabilitationment were first admitted to tertiary hospitals. Approximately 39% of patients who received delayed rehabilitation treatment were first admitted to general hospitals, and 28.5% were first admitted to primary hospitals. Conclusions: Our findings demonstrate the importance of early rehabilitation initiation and that the type of healthcare institution that the patient is first admitted to after wrTBI may influence the timing of rehabilitation initiation. The results of this study also emphasize the need to establish a Worker's Compensation Insuranceespecialized rehabilitation healthcare delivery system.

이 연구에서는 Earth Observing System Terra 위성에 탑재된 Moderate Resolution Imaging Spectroradiometer (MODIS) 협대역 방출율(채널 29, 30, 31) 자료와 다중선형회귀모형을 이용하여 지표면 광대역 방출율을 추정하였다. 다중선형회귀모형 도출 및 검증을 위한 분광 방출율 자료는 MODIS University of California, Santa Barbara와 Advanced Spaceborne Thermal Emission and Reflection Radiometer spectral library의 307종(토양 123종, 식생 32종, 물 19종, 인위적 재료 43종, 바위 90종)을 사용하였다. 도출된 다중선형회귀모형의 결정계수($R^2$)는 0.95 (p<.001)로 높게 나타났고 또한 이 모형 결과와 이론적 광대역 방출율 값의 평균제곱근오차(Root Mean Square Error)는 0.0070이었다. 그리고 이 연구 결과에 따라 계산된 지표면 광대역 방출율을 선행 연구 Wang et al. (2005)의 결과와 비교하였다. 그 결과 아시아, 아프리카, 오세아니아 지역에서 이 연구와 Wang et al. (2005)의 결과에 대한 1월 평균 지표면 광대역방출율의 평균제곱근오차는 0.0054이었고 최소와 최대 편차는 각각 0.0027과 0.0067이었으며 이러한 통계 값은 8월에도 유사하였다. 이 연구에서 다중선형회귀모형에 의하여 계산한 지표면 광대역 방출율은 Wang et al. (2005)의 값과 큰 차이가 없이 비교적 정확하게 산출되었으나 산출 정확성 향상을 위해서는 토지피복특성에 따른 차별화된 회귀모형 적용 필요성이 제기된다.

Glycated hemoglobin ($HbA_{1c}$) is a most preferably used baseline of diabetes, implicating average blood glucose levels over a 2-3 month period of time. Recently the American Diabetes Association has recommended the $HbA_{1c}$ assay as one of the criteria for diabetes. Although some studies provide data with "estimated average glucose", by converting the $HbA_{1c}$ results from simple linear regression, the results are not applicable to whole diabetes. We compared the relationship between $HbA_{1c}$ and estimated average glucose by anemia degree of diabetic patients in Korea. The data from the 2008~2009 Korean National Health and Nutrition Examination Survey were used. Analysis was done for 1,257 diabetes subjects with $HbA_{1c}$ results. The distribution of subjects was 34.1% in 60's, 25.9% in 70's, 21,6% in 50's, showing that there was more than 80% in over 50's. To take a close look of the differences depending on the anemic degree, we applied WHO criteria (hemoglobin<13.0 in men and hemoglobin<12.0 in women) and divided anemia degree. The regression equation for A1c and estimated average glucose was $eAG_{mg/dL}=24.3{\times}A1c-32.0$ ($R^2=0.54$, p<0.001) in all subjects, $eAG_{mg/dL}=33.1{\times}A1c-96.1$ ($R^2=0.52$, p<0.001) in slight anemia ($11.0{\leq}$Hb<13.0 in men, $10.0{\leq}$Hb<12.0 in women), and $eAG_{mg/dL}=13.5{\times}A1c+34.9$ ($R^2=0.12$, p =0.075) in moderate anemia (Hb<11.0 in men, Hb<10.0 in women). The regression was not significant in moderate anemia. The relationship between HbA1c and eAG was lower correlation than ADAG study, and eAG showed lower value in all ranges among $HbA_{1c}$ 5~13%. Such as a korea where, there are many diabetic patients among the old aged and higher prevalence rate of anemia, we should be extra careful when we reflect eAG using $HbA_{1c}$ and need to establish criteria which can be applicable to koreans.
