Purpose: The purpose of this study was to demonstrate the effects of visiting nursing services in long-term care (LTC) insurance on changes in health status and physical functions among the elderly. Methods: We analyzed survey data on the living status and welfare needs of the elderly from 2008 and 2011 using the difference-in-difference method with propensity score matching. Results: The subjects were 76 elders including 38 visiting nursing service users(intervention group) and 38 home-based LTC service users (control group). Results from DID analysis confirmed that the subjective health status level of the intervention group was 2.2 points higher (p=.044) and the depression level was 0.3 point lower (p=.039) than the control group. In addition, the intervention group's ADL score was 1.9 (p=.027) and IADL 3.9 (p=.030), showing that their health was deteriorated less. Conclusion: Visiting nursing service in LTC insurance was associated with delayed deterioration of subjective health status, depression, ADL and IADL. These findings suggest the need of rebuilding visiting nursing service programs focusing on prevention services, which will be more contributive to elderly health care and the reduction of social costs.

Semi-shield tunneling is one of the propulsion construction methods used to lay pipes underground between two pits named 'entrance' and 'destination', respectively. Usually a simple composition, such as 'a fiducial target at the entrance+a total station (TS)+a target on the machine', is used to confirm the planned course. However, unavoidable curved sections are present in small-sized pipe lines, which are laid after implementation of a road system, for public works such as waterworks, sewer, electrical power, and gas and communication networks. Therefore, if the planned course has a curved section, it is difficult to survey the course with the abovementioned simple composition. This difficulty could be solved by using the multiple total stations (MTS), which attaches the cross type linear LED target to oneself. The MTS are disposed to where each TS can detect the LED target at the other TS or the base point or the machine. And the accurate relative positions between each MTS and target are calculated from measured data. This research proposes the relative and absolute coordinate calculation algorithm by using three MTS to measure a curved course with 20m curvature at 30m maximum distance, and verifies the algorithm experimentally.

Objectives: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. Methods: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ${\geq}5$ for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. Results: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ${\geq}30$). Mean BMI increased with increasing psychological distress (no distress, BMI = $27.2kg/m^2$; mild distress, $27.6kg/m^2$; and moderate/high distress, $33.1kg/m^2$; p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI ($30.3kg/m^2$ for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. Conclusion: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association.

Presently, media for sanitation education consisting of a sanitation manual and a CD-ROM intended for restaurant employers and employees was developed and evaluated. The sanitation manual consisted of five principles: prevention of foodborne illness, personal hygiene, control of food production, instrument and equipment cleaning and sanitation, and management of environmental sanitation. The CD-ROM was composed of animations detailed real-life examples of Salmonella, Staphylococcus aureus, and Norovirus foodborned illness outbreaks; slides summarizing the five principles of the manual; and a poster entitled You can prevent foodborne illness listing and describing the principles. A 15 question evaluation survey was developed to gauge the efficacy of the animations. The survey was divided into five sections on comprehension of the instructions, content organization concerning understanding, content organization concerning the information presented, content organization concerning retention of interest (concentration), and recommendations concerning concentration. Ranked on a 5-point scale the survey produced a mean value of 3.80$\pm$0.39 and individual scores of 3.92$\pm$0.45 (learning instruction), 3.86$\pm$0.48 (understanding), 3.82$\pm$0.52 (information), 3.75$\pm$0.49 (concentration), and 3.67$\pm$0.58 (concentration-recommendation). Overall, evaluation results of the animation were good and easy to understand, with only a few respondents electing to watch the animations more than once. In terms of continuous and recurring education, sanitation training programs should be easy to learn and contain sufficient and specific examples of the importance of sanitation in achieving food safety.

In this study, non-point source(NPS) contribution was investigated based on flow rates and water qualities of streams into the lake during rainfall events. Event mean concentration(EMC) and the pollution loads were calculated to establish a database for NPS control measurement in the survey area, and so on. The runoff characteristics of NPS were investigated and estimated on the basis of the ratio of an agricultural to forest area in the stream of sub-catch basin during rainfall events. Non-point source pollution loads were also calculated to establish a database for NPS control measure in the upstream lake Chinyang. At a rainfall event, BOD concentrations rise sharply at the early peak time of runoff, however, peaks of TSS concentration were observed at the similar time of peak flow. This was a phenomenon shown at the watersheds caused by forest and geological types. The discharged EMC range was 2.9-4.8 mg/L in terms of BOD. The discharged EMC range was 6.2-8.2 mg/L in terms of SS. The discharged EMCs of T-N and T-P were 1.4-2.5 mg/L and 0.059-0.233 mg/L, respectively. Total BOD loading rate through the 3 tributaries to the lake Chinyang was 1,136 kg/d during dry weather. The upper watershed area of the Nam-river dam in this study was divided into 14 catchment basins based on the Korean guideline for total maximum daily load(TMDL) of water quality pollutants. The higher the agricultural land-use ratio, the more NPS loading rate discharged, but the more occupied a forest area, the lower more NPS loading rate discharged. In an agricultural land-use area more than 20%, the increase of NPS loadings might be dramatically diffused by increasing the integrated complex-use like vinyl-house facilities and fertilizer use etc. according to the effective land-use utilization. The NPS loading rates were BOD 0.3 $kg/ha{\cdot}day$, SS 0.21 $kg/ha{\cdot}day$, TN 0.02 $kg/ha{\cdot}day$, TP 0.005 $kg/ha{\cdot}day$ under less than 10% agricultural land-use. In agricultural land-use of 20%-50%, these values were investigated in the range of 0.32 $kg/ha{\cdot}day$-0.73 $kg/ha{\cdot}day$ for BOD, 0.92 $kg/ha{\cdot}day$-3.32 $kg/ha{\cdot}day$ for SS, 0.70 $kg/ha{\cdot}day$-0.90 $kg/ha{\cdot}day$ TN, 0.03 $kg/ha{\cdot}day$-0.044 $kg/ha{\cdot}day$ for TP.

Objectives : The purpose of this study was to examine the state of oral health care among special school personnels in an attempt to provide some information on the improvement of the oral health care of students with disabilities who would be under the first hand influence of school personnels. Methods : The subjects in this study were personnels who were selected by random selection in five different special schools located in the city of Jeonju, North Jeolla Province. A self-administered survey was conducted in person from July 5 to 14 after the purpose of this study was explained. Results : 1. Concerning their general characteristics, the level of oral health knowledge was high in the personnel whose career is 5 years more, and the younger personnels had a better oral health knowledge, and the men were more knowledgeable than the women. 2. As to oral health education experience, the rate of the respondents who ever received oral health education stood at 35.3 percent. In relation to the frequency of oral health education, the biggest group that accounted for 58.2 percent received that education once. As for the route of education, the largest group that represented 52.7 percent received that education at dental hospitals or clinics. In relation to satisfaction with oral health education, the greatest group that accounted for 38.5 percent were dissatisfied with that education. 3. As for an intention of receiving oral health education in the future, the biggest group that accounted for 60.9 percent intended to receive that education if they would have free time, and the largest group that represented 47.7 percent believed that oral health education should be conducted by dental hygienists. 4. Concerning their general characteristics, the level of oral health promotion behavior according to age in both bushing and supplies of oral health care was high in forties-1.89 point and 3.33 point, and that in regular visit to a dental clinic was the highest in twenties for 2.58 point, and that in dietary control was the highest in twenties for 2.59 point. 5. Their oral health knowledge had a significant positive correlation to their toothbrushing, regular dental clinic visit and dietary control that were the subfactors of oral health promotion behavior. 6. As for the impact of oral health promotion behavior on oral health knowledge, toothbrushing exerted the greatest influence on that(${\beta}$=0.306, p<0.001). Conclusions : Appropriate institutional measures should be taken to let dental hygienists who are expert in oral health care provide incremental oral health care for students and adults with disabilities in educational institutions and facilities for the disabled, and the development of oral health education programs is urgently required to offer systematic oral health education for not only students with disabilities but their teachers and guardians.
