In recent years, with the diversification of consumer needs in the market, it has become essential to respond to the increasing number of consumer products and to the sharp increases and decreases of production at production sites. In order to respond to these demands, multi-process work has been introduced with a central focus on cell production, and it has become necessary to examine the concept of work training for workers. Therefore, in this study, we focus on the difference in working skills between two cell production methods, namely, the one-person method and the division method, and we experimentally verify the relationship between work training and mastery. As a result, it was found that the division method, wherein combinations of different work factors influence the work, exerts a different influence on work learning. In addition, it became clear that work learning is achieved more efficiently by repeating the work training with the one-person method compared with a method wherein the work was subdivided into excessively small segments.

　In recent years, manufacturing companies have to create an enormous number of BOM in order to cope with the diversity of customer's preferences while taking miniaturization into consideration. Consequently, errors in BOM creation frequently occur at the manufacturing site. If an error occurs in the creation of the BOM and it is handed off to the post-process without being removed, it will seriously damage the manufacturing company. This paper focuses on review work which is an operation to eliminate errors in the process of creating configuration data, and conducts experiments to specify factors that affect the occurrence of human error in the work. By analyzing the structure of mistakes in review work, we aim for effective countermeasures against human error in BOM creation.

　In Japan, timber demand rapidly increased from the 1950s to the 1970s, so trees were planted in large numbers in various places. It is ideal that undergrowth is growing in healthy trees, and sunlight shines between the trees. Thinning is necessary to cut excess trees in order to insert it. But now, however, most of timbers imported oversea are inexpensive. Due to the declining population and aging population of primary industrial workers, we can not carry down logged trees from the mountains. Currently, there are reports that Japanese forests are insufficiently thinned nationwide. Most of the forests remain abandoned in the site and are not utilized for resources even if they are cut down in the department. Generally, the Japanese forests have many steep slopes. The situation in which market competitiveness of domestically produced timber has declined due to the distribution of price imported timber can be mentioned.

　Therefore, in our study, there are two prototypes. The first one is to make a prototype mechanical system for chipping thinned timber chips at local mountain forests and aspirating and transporting by hoses. The second one is that we will prototype a vehicle with wood tipper carrier which prevents falling by running steeply inclined mountain forest. The experiments carry out intake air transportation of wood chips, PID(Proportional-Integral-Differential) control of carrier, and vehicle rough terrain travel.

　In this paper, we discuss a problem to expand Heydari Jafar’s model. We consider an inventory control model consisting of a seller and a buyer in a supply chain. Demand is random variable. In particular, the demand during lead time is a random variable with N(λ, ξ²). The buyer uses the inventory system while keeping safety inventory larger and filling customers’ request better. On the other hand, we consider asymmetric information in our model. There are some different properties in the seller and buyer. Then, each of members must take in account how one’s own behavior is important. When we propose the seller for a replacement cycle inventory model with time-based price discount and give the buyer the requirement quantity in our model, we show that both members are win-win relationship. We can show that our model is modified to screening game problem.

　Recently, as a result of the digitized society, productivity has significantly increased since computers and robotics have replaced human laborers. Therefore, this study examines the types of labor in manufacturing for which the utilization of information technology is effective. In order to determine such effectiveness, this study extracted a sample of low-productive workers and conducted an experiment where they were asked to assemble office equipment, after which their progress was assessed using the achievement method. The results show that information technology supports “intelligent routine work” and improves overall labor productivity more than “physical routine work,” since the former requires lower levels of work learning than the latter.

　It is stated that in a knowledge creation type organization, it is important to create and activate "places" that can access real time information on external world information and update knowledge in response to that information. Regarding "places" accessing external information, it will be wide ranging from customers, suppliers, communities, industry organizations, employees' families. In this research, we examine the target of both "supplier" which forms a relatively broad industrial structure and "home" of relatively narrow range of employees for "field" which can access external information in knowledge creation type organization. As a result of the discussion, it turned out that there is a possibility that the management information system may be effective in providing "a place" for accessing external information in both the supplier who forms the industrial structure and the home of the employee.

　IoT (Internet of Things) attracts attention as one means for realizing added value creation based on the technology management strategy. In order to carry out added value creation and achieve outcomes, we think that it is necessary not only to put down the planned strategy into expedients, but also to break- down to the actual work level and specifically show it to the workers. However, focusing on IoT as a technology management strategy, there is no established tool or methodology indicating a chain-to-concrete work level. In this study, we focused on the work model of the production management work process and devised expedients the name of which we call "IoT Value Creation Sheet" implemented by IoT to realize added value creation based on technology management strategy. Which was designed as a tool to visualize the “chain” to the work level. and shows examples of its usage.

　In recent year, both standardization and the modulation are proceeding at manufacturing field. Although the standardization in manufacturing the rolling stock is over a long period of time, the modularization is yet unsolved than automobile assembling and software development. It is the reason that rolling stock is user-oriented and job order cost system. As the decrease of the railway transport volume is suspended, obsolete vehicles exchange and produce cost reduction are just required. One of above countermeasure is modularization for manufacturing. In this paper, we look back on the history of the standardization in the past rolling stock production systematically. These considerations will be useful to the modularization in the manufacturing process.

　One of the keys to improving labor productivity is to build organizational capability that will be achieve by highly utilizing both business administration and information technology (IT). Material requirements planning (MRP) and Organic binding of Management of Technology and Product Lifecycle Management (PLM) is a central role to create values in the manufacturing industry. For IT management practice, it is necessary to standardize the business across the organization from design to manufacture, and to utilize IT to achieve overall optimization. Furthermore, we have to flexibly rearrange the operations according to changes in the external environment.

　In this study, we will clarify the tasks for smartening the enterprise (smart enterprise) as a whole from design to manufacture, and clarify mechanism to contribute for the maximization of the enterprise value of the manufacturing industry by Business Rule Management System (BRMS).

　Enterprise valuation is practically important for financial activities such as stock investment and credit management. However, an applicative valuation method has not been proposed so far. The purpose of this study is to develop a valuation model that has high accuracy and predictivity. To this end, regression analysis is used with financial indices. The support vector regression model has been successfully constructed with the objective variable of market capitalization and explanatory variables of eight financial indices (current ratio, fixed assets to net worth, equity ratio, return on sales, return on assets, sales growth rate, total asset turnover, total assets). The determination coefficient of the model is 0.923 and determination coefficient with 10-fold cross validation is 0.907. Moreover, index of undervalued stocks was defined using output values of the model. As a result of verification of the index, it was suggested that the index is practically useful for stock selection. For the 100 stocks which indicate higher values of undervalued index, total return during July 2014 to June 2016 was calculated. As a result, averaged total return of these undervalued stocks was 33.3 %. On the other hand, 100 stocks having lower values of index indicate only 7.0 % for the same period. From these results, it is able to be concluded that the proposed index and the regression model are useful for enterprise valuation.

　In the audit practice, the auditor can use IT for browsing and analyzing various data, to prevent overlooking important problems and to improve the possibility of discovering new problems. In addition, it is expected that the effectiveness and efficiency of the audit will be enhanced and the effect on the accounting fraud discovery will be improved. In this paper, in order to examine the applicability of IT assisted audit for accounting fraud discovery, characteristics of accounting fraud cases of companies listed on the emerging market on the Tokyo Stock Exchange. As a result, it pointed out that collating / analyzing transaction data, cost analysis, transaction condition analysis, credit situation analysis are effective as a fundamental viewpoint of accounting fraud discovery. In the future, it is necessary to upgrade the analysis by utilizing new scenario analysis typologies.

　The decline in physical strength is young people is seen as a problem, and obesity from irregular lifestyles is thought to be one factor in this decline in physical strength. Serious problems arise in the risk from physical ability elements due to obesity factors. We investigated the major problems of obesity factors by analyzing the risk of obesity from dealing with people with severe obesity of BMI of 30 or higher. In this study various physical strength data were collected for healthy students from one university, and evaluation charts with a span covering years for each parameter were constructed. Severely obese people with BMI of ≥30 were applied to each evaluation chart, and a risk analysis was performed for physical ability elements of severely obese young people from annual trends in severe obesity. From the results it was determined that there was a declining trend in nearly all motor ability element parameters. The health parameter of blood pressure tended to be slightly high, at 130 mmHg or more. Therefore, it was shown that a major risk related to physical ability elements exists in severely obese young people.

　Swimming was introduced in education in Japan before World War II but did not spread widely as a sport until after the 1964 Tokyo Olympics. In the following years swimming spread to people swimming of a wide range of ages and was used not only in the fields of sports and education but also in child-rearing, rehabilitation, and health maintenance. In recent years the new activity of baby swimming continues to be recognized for its high effectiveness in the healthy development of infants. Behind this is the idea of using the music educational approach called eurhythmics in exercise performed in water. This study examined how the rhythmicity of eurhythmics is used in water exercise, and confirmed the benefit of water exercise in infants. Baby swimming may thus be considered to have an important position in lifelong health. This article also discusses educational productivity from use of eurhythmics, which is at the core of baby swimming.

　The wavelet interpolation model proposed by Fujii (2006) was applied in analyses using the national average data shown in school health statistical survey reports since before World War II, and height and weight growth data for children 6 to 17 years old in Miyagi and Iwate prefectures since 1955. The age at maximum peak velocity (MPV) of growth was then identified in the analyzed height and weight. The annual trends in MPV were investigated, from which slowing and accelerating tendencies that occurred in earthquake disaster environments were investigated. The results showed that there was an overall gradual lowering of the age at MPV in the national averages for both boys and girls, while the MPV age for height and weight in Miyagi and Iwate prefectures tended to occur at a little older ages starting in the 2000s. From this it is presumed that the effects of disasters may show local slowing of physical growth.

　If a simple indicator for the onset of menarche were understood, it would be easier to make advance preparations for menarche and to cope in daily life afterward. Therefore, the need for mental and physical health management of female menstruation by creating a general indicator for menarche has been indicated. However, it is difficult to accurately predict menarche, and little progress has been made in research to create a simple indicator for menarche. In this study we estimated physique (height, weight, BMI) at the time of menarche with the wavelet interpolation model as a measure of the onset of menarche that can be used with individuals and performed a regression analysis of these physique item estimates and the same physique items at the time of first grade in elementary school. In a regression analysis of height, weight, and BMI, weight and BMI were shown to have High coefficient of determination in 3 items (coefficient of determination: R²). We then performed a polynomial regression analysis of weight and BMI at the time of menarche against weight and BMI in the first grade of elementary school. Then, from a regression evaluation chart derived from the polynomial regression analysis, an indicator of the onset of menarche was specified for the categories of weight and BMI, respectively, at the time of menarche. Management of trends with the use these findings may lead to proposals for improving the productivity in health education for girls.

　Diversification strategy has been used by many firms to increase their stability and competitiveness. Different research views explain different motives, extent, pattern, and effect of diversification. However, the relationship between diversification and performance remains unclear empirically. Using the Jacquemin-Berry entropy measure, this study examines the corporate diversification and financial performance of Japanese firms in information and communications industry over the period 1999-2008. The degree of diversification has a positive relationship with per capita sales. Meanwhile, in the diversified firms progressed over a period of 5 years from 2004 to 2008, one of the measured ratios, ROA is lower than their counterparts. The paper discusses these results and offers some managerial implications, and future research opportunities are provided.

　In this study, we analyze relationship between the purpose of foreign tourist visiting Japan and the trend of their comsumption using principal component analysis. For Japan aiming for Tourism Nation, it is necessary to grasp the purpose and the consumpsion trend of visitors. We use the data of “Consumption Trend Survey for Foreigners Visiting Japan(Japan Tourism Agency)” in this analysis. The Consumption trend in European countries has a tendency toward cultural experience. Asian countries tend to be shopping. Other, the visitors from India and Germany are often business purpose. The visitors from Russia and Vietnam are often aimed at international conferences and public events. The visitors from China often buy medicines. The visitors from Australia tend to have a large consumption expenditure for ski.

　In this report, we introduce the improvement activities of the manufacturing floor through industry-Academia collaboration between the manufacturing industry in Ishikawa Prefecture and Kanazawa Institute of Technology. This initiative began in fiscal 2007 and is currently undertaken as a collaborative research. At the Manufacturing sector of four companies with production bases in Ishikawa Prefecture, 27 themes are being implemented in 9 years up to the year 2017.Initially at the beginning of this initiative, it was implemented as a long-term internship initiative that students studying management administration participate at the request of the academia, while seeking the outcome of improvement activities. In recent years, efforts have been shifting to emphasize improvement results at the request of companies. It also gives results that can be sufficiently introduced at actual manufacturing floor. We will also introduce activities after fiscal 2018.

　When the driver of the car for business causes an accident for poor physical condition due to long working hours and fatigue, human life is robbed of it, and an obstacle may be connected for a staying casualty to a body.. Ministry of Health, Labour and Welfare establishes it about prohibition of consecutive driving, the limit of on-duty hours, the securing of break strictly about the working hours of the professional driver. About the working hours of the driver of the large truck in particular, it is established by data of the record to an octopus chart paper attached to an instrument for service records carried by a truck called the tachograph or the digital tachograph to manage it. However, we need time and trouble to perform count of this recorded information every driver.

　In this study, I considered a method to manage the working hours according to a change by Microsoft Excel for efficiency of the management in the working hours of the driver and applied it to the service management of the truck driver. As a result, it was effective for the driver who could operate the Excel file on the tablet, but training to read the time according to the change from octopus chart reached the conclusion with the need when an office worker input the file of the driver who could not operate it.
