We believe that comprehensive rehabilitation can improve a patient’s overall functioning during their short term stay in SNFs. The purpose of this study is to determine if an individual’s level of independence improved after admission to a skilled nursing facility and procurement of rehabilitation services. Methods: This study retrospectively reviewed 4612 nursing home patients in California who underwent rehabilitative services at skilled nursing facilities to determine how the patients responded to their environments, therapy interventions, and any other additional supportive measures. The records of patients who were admitted for short-term rehabilitation were reviewed in a blinded fashion, looking specifically at Section GG of the Minimum Data Set (MDS). Self-Care Section GG scores recorded by rehabilitative staff provide objective data and measure patients’ levels of assistance that were required. Each activity is scored from 1, being completely dependent, to 6, being entirely independent, with varying levels of assistance with scores in between. The admission scores versus the discharge scores can be compared to determine if a patient improved their level of functioning upon discharge. Results: Utilizing the Pearson’s correlation coefficient, a strong correlation of improvement in ADL performance on Section GG between the admission and discharge scores was identified, implying significant improvement in functional independence upon discharge. The average percent improvement for Managed Care patients was ~35.4% and ~39.4% for Medicare patients. Conclusions: The results support the benefits of rehabilitation services in skilled nursing facilities, and the data suggests that admission scores can be used as a predictive tool for functional outcomes.展开更多

We predicted the extreme values of the maximum daily and hourly precipitation in Nagano Prefecture using the extreme value theory. For the maximum daily precipitation, the vales of ξ in Matsumoto, Karuizawa, Sugadaira, and Saku were positive;therefore, it has no upper bound and tends to take large values. Therefore, it is dangerous and caution is required. The values of ξ in Nagano, Kisofukushima, and Minamishinano were determined to be zero, therefore, there was no upper limit, the probability of obtaining a large value was low, and caution was required. We predicted the maximum return levels for return periods of 10, 20, 50, and 100 years along with respective 95% confidence intervals in Nagano, Matsumoto, Karuizawa, Sugadaira, Saku, Kisofukushima, and Minamishinano. In Matsumoto, the 100-year return level was 182 mm, with a 95% CI [129, 236]. In Minamishinano, the 100-year return level was 285 mm, with a 95% CI [173, 398]. The 100-year return levels for the maximum daily rainfall were 285, 271, and 271 mm in Minamishinano, Saku, and Karuizawa, respectively, where the changes in the daily maximum rainfall were larger than those at other points. Because these values are large, caution is required during heavy rainfall. The 100-year return levels for the maximum daily and hourly precipitation were similar in Karuizawa and Saku. In Sugadaira, the 100-year return level for a maximum hourly rainfall of 107.2 mm was larger than the maximum daily rainfall. Hence, it is necessary to be careful about short-term rainfall events.展开更多

Material and Methods: This study included 150 male participants. They were divided according to the levels into three equal groups: levels 5, 6, and 7 (group I), levels 8, 9, 10 (group II) and levels 11, 12, and interns (group III). This study consisted of questions related to age, gender, educational level, father’s education, mother’s education, home ownership, brushing teeth more than or twice a day, in addition to daily lifestyle habits that were daily smoking, daily use of sugary drinks, and daily use of sugary foods. Some clinical parameters of plaque-induced gingivitis and periodontitis and the percentage of radiographic bone loss were recorded. All data were collected and analyzed using Tukey’s test and Chi-square test. A P-value of less than 0.5 (p Results: One hundred fifty male dental students of different levels in the college of dentistry at King Khalid University participated in the study in three groups (I, II, and III). The mean age of group III is more than that of group II and group I, with highly statistically significant differences (p 30%) were more among the participants in group I than the participants in groups III and II. There was an increase in the percentage of affected participants with stages III and IV of clinical attachment loss (CAL), periodontal pocket depth (PPD), radiographic bone loss (%RBL), tooth mobility, as well as glycated hemoglobin (HbA1c) test values (>7%), and the number of cigarettes smoked per day (>10 cigs) in group III more than in group II and I. Conclusion: We conclude that the severity and grading of plaque-induced gingivitis were higher among the participants in group I, while the severity and grading of periodontitis were higher among the participants in group III due to the different impact of their daily lifestyle habits.展开更多

文摘Peasant painting is a kind of painting created by farmers as creative subject,bearing rich significance.According to the historical development of peasant painting in reality,the types of meaning it carried could be divided into three types in chronological order:political ideological significance,folk life significance,and creative fashion significance.These three types of meaning gave rise to three types of aesthetic utopia,namely political aesthetic utopia,folk aesthetic utopia and fashion aesthetic utopia.The three types of aesthetic utopia reflected three forms of negation and revolution of daily life.What the political aesthetic utopia resisted was the alienation force of material desire.What folk aesthetic utopia resisted was the desire for material and the binding of political ideology.The fashion aesthetic utopia opposed the relatively narrow localism.Through these three forms of resistance,the public also constructed three identities:the interpreter of their own aesthetic interpretation of political ideology,the interpreter of their own aesthetic interpretation of real life from perspective of local feelings,and the interpreter of their own aesthetic interpretation of real life from perspective of the relationship between themselves and the world.
