Organizational identity is a set of characteristics that reflect an organization's distinctiveness. The solution to the issues of organizational identity requires an individual and specific comprehension. Therefore, cross-sectional quantitative research for a pre-established category established by the researcher was difficult to perform. As a result, until now, the mainstream organizational identity studies have been qualitative rather than quantitative. However, while one aspect of organizational identity studies is to solve the question of organizational identity itself, another aspect is to solve the question of its impact on the organization. Qualitative methods may be appropriate to solve the question of organizational identity itself, but quantitative methods are better suited to solve the question regarding its organizational impact. In other words, it is possible to utilize qualitative methods to comprehend an organization's identity while using quantitative methods, for example, to measure the organizational identification of its members and conflicts that arise from the differences in directivity among its members. Research utilizing quantitative methods of this type may increase in the future.

Though lean production has its origin in the Toyota Production System (TPS), it has become popular across various industries. During this process, a striking situation has occurred in Sweden, particularly in its service industry. This paper aims to discuss the background and context of this phenomenon. In Sweden, work and management styles based on the tradition of socio-technical systems (STS), as embodied in Volvo's Uddevalla plant, used to be competing with lean production as a collection of practices observed in the Japanese automobile industry. However, once lean was viewed as a management approach that aims to create a smooth flow of value towards the customer, the integration of the two occurred. To illustrate this point, a case of a school is considered. It shows that reflection by autonomous teams of teachers play an important role in problem solving that accompanies the implementation of lean. Such an integrated style draws out workers' intrinsic motivation through involvement in problem solving, and thereby embodies the “respect for the people” philosophy in TPS. It is expected to be suitable particularly for the service context.

In most Japanese companies, regular employees work under a lifetime employment system and a seniority-based pay system. Under such conditions of no contingent money payments, we can accurately observe the phenomena associated with intrinsic motivation. Therefore, we conducted Survey X, an exhaustive survey for all employees of Company X carried out once a fiscal year, during the fiscal years 2004–2013. Using the total 13,019 employees' data of Survey X, we test a version of Deci's (1975) hypothesis that if a person's feeling of self-determination is enhanced, his or her job satisfaction will increase. As a result, there is a strong linear relationship between the job satisfaction ratio and the degree of self-determination. However, occupation and rank tend to determine the band of fluctuation with respect to the degree of self-determination. This indicates a strong likelihood that there is a spurious correlation between a degree of self-determination and a job satisfaction ratio.

等値線を引くに当って, 10mm間隔以下の狭い間隔で数字が記入してある場合には,引きにくく時間がかかりすぎ不適当である.しかし問隔が25mm以上になると,引いた等値線に個人差が大きくなり客観性の高いものが得られず不適当である.最適なのは数字が15mm間隔に,市松模様をなして配列している場合か, 20mm間隔で準市松模様に配列している場合である.以上の結論を15枚一組にした種々の数字問隔で数字を記入した図幅に,学生約50名に等値線を記入させ,一枚毎の所要時間数,基準等値線とのくいちがった面積の広狭,その個人差を比較検討した結果求めることができた.

Sepsis is a major cause of mortality in intensive care medicine. Propofol, an intravenous general anesthetic, has been suggested to have anti-inflammatory properties and able to prevent sepsis induced by Gram-positive and Gram-negative bacteria by down-regulating the gene expression of pro-inflammatory cytokines. However, propofol’s anti-inflammatory effects upon canine peripheral blood mononuclear cells (PBMCs) have not yet been clarified. Here, we isolate canine PBMCs and investigate the effects of propofol on the gene expressions of both lipopolysaccharide (LPS)-induced interleukin-6 (IL-6) and tumor necrosis factor (TNF)-α and upon the production of nitric oxide (NO). Through real-time quantitative PCR and the Griess reagent system, we found that non-cytotoxic levels of propofol significantly inhibited the release of NO and IL-6 and TNF-α gene expression in LPS-induced canine PBMCs. Western blotting revealed that LPS does significantly increase the expression of inducible NO synthase (iNOS) protein in canine PBMCs, while pretreatment with propofol significantly decreases the LPS-induced iNOS protein expression. Propofol, at concentration of 25 µM and 50 µM, also significantly inhibited the LPS-induced nuclear translocation of nuclear factor (NF)-κB p65 protein in canine PBMCs. This diminished TNF-α, IL-6 and iNOS expression and NO production was in parallel to the respective decreased NF-κB p65 protein nuclear translocation in the LPS-activated canine PBMCs pretreated with 25 µM and 50 µM propofol. This suggests that non-cytotoxic levels of propofol pretreatment can down-regulate LPS-induced inflammatory responses in canine PBMCs, possibly by inhibiting the nuclear translocation of the NF-κB p65 protein.

An attempt was made on the simultaneous analysis of the gas flow and heat transfer in the blast furnace by a mathematical model which considered complex structure and nonuniform sink and source terms for both heat and mass. ERGUN'S equation was used for the equation of motion of gas and potential flow approximation was used for the equation of solid flow. Two dimensional distribution for the velocities of gas and solid was obtained numerically by applying the finite element method with quadratic elements. Fundamental equations of heat transfer on gas and solids were composed of the terms for convection, heat exchange and heat source. Numerical computation of the fundamental equations was carried out in accordance with the method of characteristics. In this analysis, sink and source terms regarding fusion of ore in the cohesive zone and combustion of coke in the raceway were incorporated in the mathematical model as well as radial distributions of particle size and void fraction. It was consequently found that the temperature distribution was affected principally by nonuniform gas flow and thermal flow ratio. Within the cohesive zone, strong consumption of heat by fusion of ore and decrease in the solids velocity appeared. These phenomena affected significantly the temperature distribution in the lower region of the blast furnace together with the generation of heat in the raceway region.

Antithrombotic drugs have been increasingly used for treating ischemic cardiovascular diseases among the elderly in Japan. However, antithrombotic drugs are known to be risk factors for gastrointestinal injury. Therefore, we conducted a pharmacoepidemiologic study on patients receiving antithrombotic drugs to identify the risk factors for gastrointestinal injury. This retrospective case-control study included patients who were prescribed antithrombotic drugs at the Ehime University Hospital between April and September 2010. Of the 3271 patients who received antithrombotic drug therapy, 172 (5.3%) developed gastrointestinal injuries, including gastric ulcers, duodenal ulcers, and hemorrhagic gastrointestinal injuries. Further, the incidence of gastrointestinal injury was higher in patients with hypertension than in those without (p<0.0001). Multivariate adjusted odds ratios and 95% confidence intervals were calculated using stepwise logistic regression. The adjusted odds ratios for gastrointestinal injury were 1.56 (95% confidence interval 1.07–2.36) for hypertension, 1.70 (1.17–2.50) for low-dose aspirin, 2.77 (1.70–4.49) for clopidogrel, 1.95 (1.23–3.08) for warfarin, and 4.13 (2.88–5.95) for nonsteroidal anti-inflammatory drugs. On the other hand, the non-adjusted odds ratio for drug-associated gastrointestinal injury was 0.43 (0.20–0.84) for eicosapentaenoic acid (EPA). In addition, we found that patients aged 70 years or older were at increased risk of drug-associated gastrointestinal injury. These findings suggest that while many antithrombotic drugs are risk factors for gastrointestinal injury, EPA may be a safe option for suppressing or preventing gastrointestinal injury.

As an engineer who has devoted himself in the nuclear industry for almost three decades, the author gave a personal view on educating two-phase flow and developing human resources. An expected role of universities in on-going discussions of collaboration among industry-government-academia is introduced. Reformation of two-phase flow education is discussed from two extreme viewpoints, the basic structure of physics and the practical system analysis.

Because of an increasing demand on electric power and limited resources for conventional fuels, highly efficient engine that is capable of converting energy resource to electric power with a small loss is awaited. In this respect, Stirling engine provides a strong potential because of its efficient thermodynamic cycle, which is ideally close to the theoretical limit of the Carnot cycle. Practical use of the Stirling engine, however, has been limited because of its low output power. Towards its wider applicability, simultaneous operation of many individual Stirling engines is indispensable to increase the output power. This paper presents an experimental study of synchronized dynamics of two coupled Stirling engines. It is shown that the synchronized operation of the population of engines provides a key technology to extend the system size so as to produce a large-scale electric energy.

デフォルト・モード・ネットワークは,外的な処理を行っているときは活動が低下し,内的な処理を行っているときに活動増加を示す神経ネットワークである.筆者らは,映像観察時の瞬きに関連して,脳の中では,デフォルト・モード・ネットワークが一過性に賦活する一方,注意の神経ネットワークの活動が一過性に抑制されることを発見した.行動研究により,映像情報の暗黙の切れ目で,人々が一斉に瞬きをしていたことから,瞬きは連続した視覚情報の分節化と関係していることが推測される.このことから,外的に注意を向けている状態でも,瞬目に伴い,拮抗する神経ネットワークの状態を一過性に変動させることで,注意を内的に解除し,情報の分節化が行われていることが示唆される.この発見により,デフォルト・モード・ネットワークは,内的処理を担っているだけでなく,他の神経ネットワークと相互作用することで,積極的な認知処理機能を担っている可能性が考えられる.
