The purpose of this study was to clarify the status of ward nurses' oral observation performance and factors associated with the performance. The data of 334 ward nurses' responses were used for the analysis. The results of the analysis showed that the rate of their observation performance of saliva and dental pain were less than half, and the status of their observation performance was different among department they belonged to. And higher age, longer length of nursing experience, and stronger collaboration with oral health professionals were significantly associated with their oral observation performance. Only a perception that “the experience of using OAG (Oral assessment guide) was effective in the observation of oral pain” in the categories of oral assessment sheet was associated with their oral observation performance although other perceptions in the categories of oral assessment and the experience of using OHAT (Oral health assessment tool) were not associated with the performance. Therefore, it is suggested that education and appropriate practice settings regarding oral care are neeed t pote tir aopriate oralobservio and oral c performnce

Food loss is a big problem all over the world. Many recommendation methods for cooking recipes are proposed in previous research. But the total cost of food loss is not minimized in the previous research. In this research dynamic programming is applied to minimize the total cost of food loss in recommendation method for cooking recipes. A new recommendation method is proposed. In the proposed method new recipes are created by substituting the ingredients in existing recipes with other ingredients using ingredient thesaurus. The effectiveness of the proposed method is shown by some experiments. In the experiments the food loss of the proposed method is confirmed to be smaller than the food loss of the empirical recommendation method. The proposed method is expected to contribute to the reduction of f od loss in households. The optimal solution of the proposed method is also a theoretical limit. The theoretical limit can be used to evaluate other recommendation methods. The application of the proposed method to healthcare is a topic of the future.

Increasing profit is desired in Japanese agriculture. There is many previous research on profit maximization in agriculture. In previous research the profit of crop rotation is maximized. But the previous research is studied under the condition that the price of crop is constant. In General price of crop changes. In this research the profit of crop rotation is maximized under the condition that the price of crop changes depending on Markov chain. The profit is maximized by dynamic programming. The effectiveness of the proposed method is shown by some simulation examples. The profit of the proposed method is greater than that of the comparison target. In the results of the proposed method the adaptive crop selection according to the fluctuating crop price was confirmed. The optimal solution of the proposed method is also a theoretical limit. The theoretical limit can be used to evaluate other crop rotation methods. The proposed method is expected to contribute to the automation of decision making in smart agriculture.

Few studies have examined the claim that engaging in safety activities can contribute to the reduction of occupational accidents in the workplace. Maintenance and promotion of these activities are largely influenced by team communication about safety. Team Communication Interface Questionnaire (TCIQ) has been proposed to examine intra-organizational communication by asking members to share their impressions about their team. Derived from TCIQ, we have developed Safety Communication Interface Questionnaire (SCIQ) to measure impressions of safety in the workplace. In this study we conducted a questionnaire survey and workplace inspection for Company A, examined the reliability and validity of SCIQ, and evaluated safety activities from the viewpoint of safety communication. The 115 subjects had a mean age of 48.3 years and were recruited from the company's two branches. Cronbach's alpha coefficient was used to calculate the internal consistency coefficients of the items in SCIQ: risk prediction activity (0.764), near-miss activity (0.815), 4S activity (0.765), pointing and calling activity (0.807), and greeting movement (0.755). The results of this study demonstrate the reliability of SCIQ.

The purpose of this study is to construct a multiple regression equation that predicts the length of hospital stay for NICU and GCU using information obtained at the time of admission, and to verify the cross-validity of the prediction equation using test cases. The subjects were 1280 NICU and GCU inpatients and divided into 1149 model construction cases and 131 test cases by the Hold-Out method. The information obtained at the time of admission was used as an explanatory variable, and a hierarchial multiple regression analysis was using the number of days of hospitalization until discharge as the objective variable. The AIC value was obtained from the obtained model and the optimal statistical model was selected. The explanatory valiables of the selected model were weight at admission, gestational day, head circumference at admission, Apgar score 1 minutes, Apgar score of 5 minutes, presence of obstetric abnormalities, transvaginal delivery, cesarean delivery, primiparity and delivery. Comparison of the actual length of hospital stay with the predicted length of hospital stay in the test case showed no significant difference and showed a high correlation,supporting the cross-validity of the subjects at the facility.

This study confirmed the effectiveness of the pa-ta-ka-ra exercise (oral functional training) for patients with mental disorders. We instructed some patients with mental disorders receiving inpatient treatment to perform the exercise every day for 6 months. Before and after the exercise period, we measured each patient's frequencies of producing 3 sounds: “pa”, “ta”, and “ka”, using an oral movement measurement device. As a result, we analyzed the data of 31 patients who measured it. Before the exercise period, the patients' frequencies of producing “pa”, “ta”, and “ka” were generally low, indicating oral dysfunction. After performing the pa-ta-ka-ra exercise for 6 months, the frequencies significantly increased. When one of the 3 sounds was more frequently produced, the frequencies of producing the 2 other sounds also tended to increase. The results of the present study support the effectiveness of the pa-ta-ka-ra exercise as an oral functional training method for patients with mental disorders.

Traditionally, information on travel has been obtained from travel magazines, television and travel agents. Recently, it is commonplace to use the Internet as a means of collecting information on sightseeing and recreation. Visitors to a sightseeing spot transmit their experiences and impressions through blogs and social networking service (SNS). For this reason, it is essential to transmit and collect information on the Web for the promotion of tourism and regional development. In this paper, we collect regional information from the vast amount of data that exists on the Web for use in tourism promotion and regional development. The purpose of this paper is to extract useful knowledge from that information by using text mining. We focused on Twitter, which has a high degree of breaking news and diffusion among many social networking sites. And because of its suitability for various kinds of knowledge. We collected data posted around Shimonoseki City, and extracted data on tourism from them in order to gain knowledge about tourism. Tourist destinations that are talked about in social networking sites may be different from traditional tourist destinations. We will collect data on tweets posted around Shimonoseki and consider whether we can find new tourism resources.

The purpose of this study was to obtain the basic materials for volunteers who participated in the "sports experience programs for visually impaired children" for their own recognition and future participation of volunteers. As a result of analyzing 75 valid answers obtained from volunteers, 12 categories were created as "changes in interaction of participating children during training" and 1 categories as "changes of volunteers themselves through training" captured by the volunteers themselves. From these results, when we examined the relationship with the whole volunteer using a biaxial matrix of "non-daily-daily" and "passive-active", it became clear that it was positioned as "active-non-daily". It was. Furthermore, by structurally grasping "passive-active", in addition to the higher level of recognition and the specialized knowledge about disabilities, which will help future volunteers to capture the meaning and value leading to the emergence of the phenomenon in front of them, This suggests the need for specialized knowledge necessary for coaching to promote performance.

The purpose of this study was to investigate nurses' knowledge, awareness, and confidence in relation to oral health care and compare them according to clinical departments. A questionnaire was distributed to 435 nurses who worked at four hospitals. Data were collected from July 2018 to August 2018. The questionnaire evaluated their levels of knowledge, awareness, and confidence regarding oral health care and their levels of evidence-based knowledge regarding oral health. The levels were measured by a percentage scale (0-100%) and compared among departments using an ANNOVA. A total of 351 nurses (male, n=20; female, n=331) responded to the questionnaire. The average percentages for knowledge, awareness, and confidence were 48%, 76%, and 54%, respectively. The average percentages for knowledge regarding oral bacteria categories were low (36-75%), while the average percentages for knowledge regarding the nutrition and oral function categories were high (69-84%). In comparison to nurses in other departments, the levels of knowledge, awareness, and confidence among nurses in the palliative care department were more likely to be high. The levels of knowledge regarding oral bacteria and confidence in the performance of oral health care were low among nurses. There were significant differences of knowledge, awareness, and confidence regarding oral health care among clinical departments. Thus, it is suggested that an oral health care educational program, which takes into account those problems identified in the present study, should be developed.
