This paper aims to evaluate the applicability of dam inflow prediction model using recurrent neural network theory. To achieve this goal, the Artificial Neural Network (ANN) model and the Elman Recurrent Neural Network(RNN) model were applied to hydro-meteorological data sets for the Soyanggang dam and the Chungju dam basin during dam operation period. For the model training, inflow, rainfall, temperature, sunshine duration, wind speed were used as input data and daily inflow of dam for 10 days were used for output data. The verification was carried out through dam inflow prediction between July, 2016 and June, 2018. The results showed that there was no significant difference in prediction performance between ANN model and the Elman RNN model in the Soyanggang dam basin but the prediction results of the Elman RNN model are comparatively superior to those of the ANN model in the Chungju dam basin. Consequently, the Elman RNN prediction performance is expected to be similar to or better than the ANN model. The prediction performance of Elman RNN was notable during the low dam inflow period. The performance of the multiple hidden layer structure of Elman RNN looks more effective in prediction than that of a single hidden layer structure.

The purpose of this hermeneutic study was to investigate the meaning of "good dying" of Chinese terminally ill cancer patients in Taiwan; the factors related to this morning; and the strategies cancer patients used to ensure "good dying". Indepth unstructured interviews, prolonged participant observations, and review of clinical records were selected as the methods for data collection. In the four and one-half month period of data collection, the researcher was in the role of a full time clinical nurse specialist who directly took care of the subject patients in 4 hospitals and in patients' homes. The 20 subject were selected purposively according to selection criteria and various demographic backgrounds. Interview transcripts and field notes comprised the data for analysis. The results were composed by 3 constitutive patterns and 12 themes. Achieving inner peace appeared to herald the good dying state. The "good dying" for Chinese terminally ill cancer patients in Taiwan meant peace of body, peace of mind, and peace of thought. The constitutive pattern of peace of body included 4 themes: (1)minimizing the agony of physical symptoms; (2)short period of dying process without lingering death; (3) cleanliness, neatness, and integrity of the body; and (4) mobility. The constitutive pattern of peace of mind included 5 themes: (1) yielding; (2) non-attachment; (3) not to be lonely; (4) settle down all affairs; and (5) being in a preferred environment and enjoying nature. The third constitutive pattern of peace of thought included 3 themes: (1) getting through day by day without thinking; (2) meaningful life; and (3) expectation that the suffering would be ending. Through understanding of the terminally ill cancer patient' needs in their meanings of "good dying", recommendations can be made for humanistic care. The findings of this study have recommendations for care givers daily contact with dying patients and for medical and nursing education.

Failure data of systems in many field can be erroneous, which influences the reliability analysis of the systems. The general form of failure data is right censored data with accurate time information. But due to its nature of data collection in the military field, failure time of one-shot weapon systems can have errors which are related to the maintenance period. So this paper suggests a model that can reduce the error by utilizing interval censored data as an alternative to right censored data in weibull distribution.

Elevated plasma homocysteine is an independent risk factor for the development of cardiovascular disease. Exercise is generally believed to reduce the plasma homocysteine levels and therefore, being beneficial for cardiovascular disease (CVD). However, there is a possibility that athletes undergoing strenuous training and competition which increase oxidative stress may suffer from increased plasma homocysteine levels. The purpose of this study was to investigate the influence of endurance training on the plasma concentrations of B vitamins and homocysteine in 23 male adolescent field hockey players. Data collection and blood sampling was performed during the training period and non-training period. Following the training period, significant changes in energy and vitamin B6 intakes were observed in these subjects. Plasma vitamin B2, pyridoxal phosphate (PLP) and homocysteine levels were significantly higher during the training period than non-training period, whereas no difference was observed in plasma folate and vitamin B12 levels. Positive correlation was observed between plasma folate and folic acid intakes. When energy, B vitamin intakes were adjusted there was a significant negative correlation between plasma homocysteine levels and plasma riboflavin, folate and vitamin B12 levels. In conclusion, it is suggested that athletes with oxidative stress by strenuous exercise may need B vitamins since riboflavin, folic acid and vitamin Bl2 were shown to be negatively correlated with plasma homocysteine in athletes during the training period.
