The weather in Nagano Prefecture, Japan, can be roughly classified into four types according to principal component analysis and k-means clustering. 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.
Background: Self-care tasks or activities of daily living (ADL)’s performance are often disrupted after an older adult sustains an injury or illness, which can be a determining factor for discharge placement after hospitalization, or it can determine the level of assistance required after discharge from a skilled nursing facility (SNF). 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 sugges
