Characteristic Duties of Critical Care Nurses in Japan: A Time-Study Comparison with Neurology Ward Nurses

Open Journal of Nursing 2016年第12期6卷 1038-1051页

Background: The importance of the acute phase in hospitals has been increasing. While administering high-level critical care, the working styles of critical care nurses, the types of clinical care they provide, and the way in which they prioritize tasks, remain unclear. Aim of this study was to elucidate the characteristic duties of critical care nurses through a comparison with neurological ward nurses. Methods: We recorded the duties of critical care nurses and neurology ward nurses (10 each) using a time-study design. Duties were measured separately by action, classified using a classification table, and differences between the two groups were compared. Results: No differences in the number of actions were observed between the two groups. The top five items that required the most time for critical care nurses were, “Movement”, “Administration and oxygen management”, “Handover process/Doctor’s rounds”, “Preparation for entry and exit management of patients”, and “Bed bathing (for bedbound patients)”. Of the 195 items, significant differences between the groups were noted for 34 items, while the duties of critical care nurses were best characterized by bed bathing (for bedbound patients), changing position, confirmation of infusion tubes, handover process/doctor’s rounds, and preparation for entry and exit management of patients. Conclusion: A characteristic of critical care nurses is that they must remain near patients and perform tasks while moving only a short distance. Moreover, the promotion of tasks while communicating with physicians is presumed to play a role in the promotion of team medicine. Furthermore, much time was spent caring for patients in bed, and a lot of time was devoted to the preparation and finalizing of treatments and care, suggesting the possibility that more time can be spent on caring for patients through a revision of duties.

Hand-holding and releasing between the anion and cation to change their macroscopic behavior in water

引用

Green Energy & Environment 2019年第2期4卷 127-130页

作者： Kosuke Kuroda yumiko Shimada Kenji Takahashi Faculty of Biological Science and Technology Institute of Science and Engineering Kanazawa University

Despite the similarity of ionic liquid and zwitterion, their some properties such as conductivity and hydrophobicity are different. Here we developed a novel phosphonium salt having a dynamic covalent bond between anion and cation, enabling reversible structural shift between free ion pair and zwitterion. With the phosphonium salt, control of the macroscopic phase behavior in aqueous solution, i.e. forming mono-or biphasic systems, upon exposure to an acid or base was reversibly achieved, based on the structural shift of the phosphonium salt. CO_2/N_2 bubbling reversibly changed the phase behavior as well as acid/base, leading to green separation systems.

Effect of Plate Position and Size for Self-Induced Flow Oscillation of Underexpanded Supersonic Jet Impinging on Perpendicular Plate

引用

Journal of Thermal Science 2011年第3期20卷 238-241页

作者： Tsuyoshi Yasunobu yumiko Otobe Hideo Kashimura Department of Control & Information Systems Engineering Kitakyushu College of Technology Sii Kokuraminami-ku Kitakyushu-shiFukuoka 802-0985 Japan

When the underexpanded supersonic jet impinges on the obstacle, it is well known that the self-induced flow oscillation occurs at the specific condition of the pressure ratio in the flowfield, the position of an obstacle and so on. This oscillation is related with the noise problems of aeronautical and other industrial engineering so that the characteristic and the mechanism of self-induced flow oscillation have to be cleared to control the various noise problems. But, it seems that the characteristics of the oscillated flowfield and the mechanism of oscillation have to be more clear to control the oscillation. This paper aims to clarify the effect of the plate position and the width for the self-induced flow oscillation of an underexpanded supersonic jet impinging on the perpendicular plate by the experiment and the numerical analysis. From the results, it is clear that the occurring domain of the self-induced flow oscillation and its dimension strongly depend on the plate position and the width.

Characteristic and Mechanism of Pressure Fluctuation Caused by Self-Induced Oscillation of Supersonic Impinging Jet

Journal of Thermal Science 2013年第2期22卷 123-127页

作者： Tsuyoshi Yasunobu yumiko Otobe Hideo Kashimura Department of Control & Information Systems Engineering Kitakyushu College of Technology

When the underexpanded supersonic jet impinges on the obstacle, it is well known that the self-induced flow os- cillation occurs. This oscillation depends on the pressure ratio in the flowfield, the position of an obstacle and is related with the noise problems of aeronautical and other industrial engineering. The characteristic and the mechanism of self-induced flow oscillation, have to be clarified to control various noise problems. But, it seems that the characteristics of the oscillated flowfield and the mechanism of an oscillation have to be more cleared to control the oscillation. This paper aims to clarify the effect of the pressure ratio and the obstacle position and the mechanism of self-induced flow oscillation by numerical analysis and experiment, when the underexpanded su- personic jet impinges on the cylindrical body. From the result of this study, it is clear that occurrence of the self-induced flow osciUation depends on the pressure balance in the flowfield.

Generation of Overpressure due to Condensation in Moist Air Jet

Journal of Thermal Science 2007年第2期16卷 145-148页

作者： yumiko OTOBE Hideo KASHIMURA Shigeru MATSUO Masanori TANAKA Toshiaki SETOGUCHI Kitakyushu National College of Technology 5-20-1 ShiiKokuraminamiKitakyushuJapan Saga University 1HonjoSagaJapan

In the present study, a computational fluid dynamics method has been applied to investigate the effects of initial degree of supersaturation at reservoir condition on under-expanded sonic jet structures, such as Mach disk location and diameter, barrel shock wave and jet boundary. The axisymmetric nozzle geometry investigated was a converging nozzle with straight part. As a result, it was found that the overpressures due to condensation generate and the characteristics of flow with generation of overpressure due to condensation in the jet were different from those without condensation.

Acute respiratory distress syndrome associated with severe ulcerative colitis

World Journal of Gastroenterology 2010年第19期16卷 2440-2442页

作者： Shiho Sagara Yasuo Horie yumiko Anezaki Hideaki Miyazawa Masahiro Iizuka Health Care Center Akita Red Cross Hospital Akita 010-0001 Japan Department of Internal Medicine Akita University School of Medicine Akita 010-8543 Japan Department of Surgery Akita University School of Medicine Akita 010-8543 Japan

Various extraintestinal manifestations including pulmonary abnormalities have been reported in patients with ulcerative colitis. Acute respiratory distress syndrome (ARDS) is a serious and fatal pulmonary manifestation. We have experienced a 67-year-old male patient with ARDS associated with a severe type of ulcerative colitis (UC). Severe dyspnea symptoms occurred during the treatment of UC in a previous hospital and the patient was transferred to our hospital on June 27, 2007. Both blood and sputa cultures for bacteria and fungi were negative. Cytomega-lovirus antigenemia was also not detected. From the clinical and radiological [Chest X-ray, computed tomography (CT)] findings, the patient was diagnosed with ARDS on the basis of the def inition of ARDS developed by the European-American Consensus Conference on ARDS. Both colonic inflammations and ARDS symptoms of the patient were resistant to any medical treatment includingcorticosteroids and antibiotics. However, ARDS symptoms were dramatically improved after surgical colectomy. We believe that severe colonic inflammation from UC was closely associated with the onset of ARDS of the patient. Our case report suggests that a severe type of ulcerative colitis might be taken into consideration as one of the predisposing factors of ARDS.
