The function evaluation coefficient II in DPC / PDPS is said to be “an evaluation of incentives for improving the efficiency of the entire medical care provision system by participating in DPC / PDPS.” In this report, I examined whether this function evaluation coefficient II is an incentive for management, targeting hospitals subject to DPC in 2019, and public enterprise hospitals whose income statement is published in the same format. The analysis method used multiple regression analysis with medical practice revenue per 100 beds, medical practice costs, medical practice balance, and current account balance as objective variables, and the breakdown of function evaluation coefficient II as explanatory variables.

As a result, it was found that the function evaluation coefficient II had a significant positive effect on both medical practice revenue and medical practice cost as a whole, but did not reach a sufficient incentive from the difference in slope. By coefficient, the coverage coefficient has a positive effect on both the medical balance and the current balance, the quantitative evaluation coefficient (other than children) has a positive effect on the medical balance, and the complexity coefficient and the quantitative evaluation coefficient (children) have a positive effect on the current balance. However, the insurance medical treatment coefficient did not mean a significant effect on the balance. Furthermore, it was found that the efforts to shorten the length of hospital stay, which are seen in the efficiency coefficient, have a negative effect on the current management situation and are not linked to management. We believe that considering costs as a more appropriate coefficient by calculating costs will lead to incentives for efficiency improvement, which is the purpose of introduction.

Objective：To clarify factors that enable end-of-life home care for older adults, and establish systems to provide such care with community residents participating or mutually supporting in heavy snowfall areas, we performed a narrative analysis of main caregivers with experience in providing end-of-life home care for their families.

Methods：We con-ducted semi-structured interviews with 13 family caregivers who pro-vided end-of-life home care for older adults using home-visit medical/nursing services of a prefectural hospital after consenting to its end-of-life home care policy, and qualitatively and inductively analyzed the obtained data to clarify factors that enabled such care.

Results：From the perspective of these families, the following factors enabled end-of-life home care: care-receiver-related: 1) the desire to die at home and 2) painless home care; and caregiver/family-related: 1) a firm intention to provide end-of-life care for the care-receiver, 2) readiness to be in charge of such care, and 3) lower subjective caregiving burden. Regarding formal support, 24-hour home-visit medical/nursing services with: 1) doctors/visiting nurses who provide support at all times and 2) mental preparedness for end-of-life care; and seamless formal support systems based on: 1) end-of-life home care support through multi-institutional collaboration were identified. As for informal support, 1) the presence of other community residents/blood relatives who provide support in an informal manner; and 2) the presence of other community residents/blood relatives who are empathetic to the care-receiver were identified.

Discussion：Factors that enable end-of-life home care may also promote the QOL of families by reducing their caregiving burden and increasing their satisfaction/sense of accomplishment after end-of-life care, in addition to promoting the QOL of care-receivers and peaceful deaths.

Objective：To address the three pending issues that were raised after the release of B.I.T. (Bayesian inference tool). A Bayesian inference visualization tool expands the user experience by providing support to multiple platforms; it adds robustness to calculations instead of approximation and offers various inference visualization options other than the normal distribution.

Method：Using Python3, NumPy, SciPy, and the plotting tool Matplotlib, we created a new Bayesian inference visualization tool that runs on multiple operating systems and assures a robust calculation of the posterior probability. In addition, new cases of Bayesian inferences other than the normal distribution were collected for visualization.

Results：The newly developed B.T.V.T.I. (Bayesian tool for various types of inferences) runs on Windows, macOS, and Linux (Ubuntu). It is a software program with twelve Bayesian inference visualization screens, out of which nine have the statistical function implementation of SciPy. The program calculates and displays graph curves of the posterior distribution and posterior probability values at the same time as the observed values and variables are input. However, because a different programming language is used, its operation screen is different from that of B.I.T.

Discussion：The future expandability of B.T.V.T.I. to other devices, the application and limits of SciPy, and future implementation and visualization of the uncited Bayesian inference cases were discussed. Ideally, users must be familiar with the principle, premises, and applications of the Bayesian inference to use this software.

In recent years, large-scale disasters have occurred frequently and caused enormous destruction. The aim of this study was to clarify the factors related to the formulation status of the business continuity plan (BCP) of disaster food-related companies.

Methods：A mail survey was conducted in 566 disaster food-related companies that are members of the five industry groups. The survey period is from March 5, 2018 to September 20, 2018, and the formulation of BCP, and the implementation status of education and training and food in case of emergency. A system of cooperation and cooperation regarding supply was established.

Results：The survey forms were collected from 136 companies (24.0%). BCP-developed companies tended to stockpile multiple food and heat sources compared to undeveloped companies. Factors related to BCP formulation include as follows: (1) feeling that it is important to be prepared to protect company from natural disasters (p=0.035), (2) implementation of education and training for business continuity (p<0.001), (3) disasters with prefectures, and municipalities concluding a time support agreement (p=0.043), and (4) arrangements for exchanging information during disasters with national and prefectural governments (p=0.001) were mentioned.

Conclusion：It is suggested that the formulation of BCP requires consideration for health and the environment, including stockpiling food and heat sources, as well as education and training, and it is considered necessary to continue to work toward formulation and renewal. In addition, it is desirable to build a face-to-face relationship with local governments, companies, health care and welfare organizations, and disaster prevention related organizations, on a daily basis.

Purpose：The purpose of this study was to examine the current situation and issues of care workers regarding the collaborative ability of care workers.

Method：Interviews were conducted with 6 care workers working at 3 different nursing home for the elderly. The Interview data were analyzed by using SCAT (Steps for Coding and Theorization), which is a qualitative analysis method.

Results：We generated fifteen constructs. It was suggested that the characteristics of care workers who have issues on collaboration are (1) taking self-centered actions, (2) refusing communication, (3) not being able to perform additional tasks, and (4) not being able to speak their true intentions.

Discussion / Conclusion：It was suggested that the four characteristics are factors that human relations with other care workers and make it difficult for care workers to collaborate with each other.

In the baseball world, there is currently considerable discussion about the prevention of pitching obstacles by limiting the number of balls and innings regardless of age. Junior high school students are in a development stage, and their physical balance is likely to change substantially. This study investigated number of pitchers and pitches in official and practice baseball games of junior high schools. We surveyed 298 teams belonging to the Niigata Junior High School Physical Culture Association. The survey period was divided into two periods (the first half and the second half). The first half was from March to July 2019 and the second half was from July to November 2019. As a result, the average num- ber of pitches per game was 1.68±0.73 in the first half of the official game, 1.89±0.77 in the second half, 2.16±0.97 in the first half of the practice game, and 2.23±0.94 in the second half. Official games had significantly fewer pitchers per match than practice games in both terms. The percentage of pitchers who completed games was 46.6% in the official game in the first half, 25.7% in the practice game, 32.9% in the official game in the second half, and 19.7% in the practice game. Compared with official games, practice games also had a sig- nificantly lower percentage of pitchers who completed games. Official games had an aver- age of 92.1±24.3 pitches in the first term and 89.9±20.6 pitches in the second. Further research is needed to identify factors that can reduce average participating-pitcher num- bers per game, considering the number of team members and their skills. In addition, the medical basis of guidelines for optimal pitch counts should be clarified.

The pass rate of the national qualification exam is of utmost concern for medical colleges because students enrol with the goal of obtaining the national qualification. We proposed a method that can estimate the passing probability of each student’s national exam and the passing rate of the department, at the time of 1 year before the exam. This is to make it possible to consider whether the same measures as last year are sufficient or whether the measures need to be changed based on specific data. Based on the results of the one-year mock tests of a department with a capacity of 40 students and the actual pass/fail data, the probability of passing how many of the students who scored the mock test at a certain time passed for the national exam was calculated for each score. This probability and change over time were modelled by a line graph. This model was applied to data for other years. As a result, the probability of passing the actual exam when each student made the same effort as last year could be calculated from the score of each mock test. By adding up the probabilities, we were able to estimate how many people could pass in the department. As for the results for 4 years, if the value obtained by dividing the predicted pass rate by the actual pass rate is taken as the reliability, the reliability as of 2 months before each year was 0.86, 1.00, 0.99, 1.13. The ideal scenario is to change the measures if the initial prediction is bad, then the prediction just before the exam will have a pass rate of 100%, and 100% pass on the day of the national exam can be achieved.

The purpose of this study is to understand the difficulties faced by teachers in dance classes and to obtain materials that can be used as countermeasures to solve the problems. A survey method via a questionnaire was used, targeting elementary and junior high school physical education chiefs in Niigata City. Inquiry about the actual conditions of expression dance lessons, difficulties in teaching, and the effects and requests of attending classes ensued. As a result, three types of dance presented by the national curriculum were selected evenly in elementary school. Rhythmic dance was opted in junior high school and emphasized regardless of the skill level of teachers. Generally, unskilled instructors face hardship in teaching compared with skilled instructors. In particular, from the perspective of <class making and teaching methods>, skill evaluation perspectives, lesson composition methods, and children, I felt that I was subpar at interacting with children during the class, apropos of speaking to students. Contrarily, it established that skilled leaders have a problem eliciting diverse and free creative movements and improvisational expressions. As for attending dance classes, teachers discern that dance instruction classes for teachers are more utilized in the teaching field than taking dance classes at university. Further, there is an opportunity to learn teaching methods. Therefore, it was proposed that teachers should seek knowledge and utilize practical methods for systematic learning tasks and lesson unit composition.

In recent years, domestic violence (DV) has become more widely recognized as a social problem. It has been pointed out that it is necessary for both victims and perpetrators to be involved to prevent the recurrence of DV. However, in the current situation, only some private organizations provide support to the perpetrators. Therefore, we aim to overcome the current issues relating to the DV perpetrator program in Japan. This study was conducted to examine a new support model.

Through an interview survey, we found that the shortage of human resources with expertise in the DV perpetrator program was a serious problem. Therefore, not only the executive agency of the perpetrator program but also the damage required improvements. We think that it is necessary to strengthen the cooperation between in-person support organizations and administrative consultation staff to solve the current problems. In addition, from the survey results of this study, it was found that there are many cases in which the perpetrator participates in the perpetrator program by persuading or recommending the victim.We also learned that there are many cases of participation in the program. The new support model, that is, “the relationship-building model,” could allow the victim and the perpetrator, if they wish to do so, to choose the option of repairing or rebuilding their relationship.

Most of the work processes in a pathology laboratory are performed manually by multiple medical technologists; therefore, human error is more likely to occur in examinations performed in pathology laboratories than medical examinations performed in other departments. Thus, our hospital uses “Laboratory Note” as a part of the medical safety management. The information management from this note is operated within the pathological examination system of the Laboratory Information System. So far, reports have emphasized on the importance of incident report and quality management systems in pathological laboratories; however, there have been no research reports on medical safety management using the Laboratory Note.

This study included 527 cases reported in the Laboratory Note from September 2015 to August 2019. These cases were stratified into 30 categories, and a series of examinations were classified into three categories: pre-examination, examination, and post-examination, and the number of reports by year was also tabulated. The most frequently reported category was pathology number management in 53 cases (10.1%). In addition, the number of categories reported during the examination process was the highest at 20 types and 287 cases, followed by 18 types and 166 cases before the examination. Moreover, there was a negative correlation with the number of annual changes and the number of reports.

Records are indispensable for medical safety management in pathological laboratories. The members of the pathology laboratory recorded and shared the various risks and challenges they have experienced during their work in the Laboratory Note. Occasionally, unexpected events can occur daily. The aim of this study was to establish corrective measures to prevent errors from developing into major setbacks.

This paper suggests the importance of risk management in pathological and cytological examinations by risk-assessing the events recorded in this study.
