A Branch-and-Bound Based Heuristic Algorithm for Minimizing Makespan in Machining-Assembly Flowshop Scheduling  [PDF]
Kazuko Morizawa
Engineering (ENG) , 2014, DOI: 10.4236/eng.2014.613081
Abstract: This paper proposes a heuristic algorithm, called list-based squeezing branch and bound algorithm, for solving a machine-fixed, machining-assembly flowshop scheduling problem to minimize makespan. The machine-fixed, machining-assembly flowshop consists of some parallel two-machine flow lines at a machining stage and one robot at an assembly stage. Since an optimal schedule for this problem is not always a permutation schedule, the proposed algorithm first finds a promising permutation schedule, and then searches better non-permutation schedules near the promising permutation schedule in an enumerative manner by elaborating a branching procedure in a branch and bound algorithm. The results of numerical experiments show that the proposed algorithm can efficiently provide an optimal or a near-optimal schedule with high accuracy such as mean relative error being less than 0.2% and the maximum relative error being at most 3%.
Professional identities of occupational therapy practitioners in Japan  [PDF]
Risa Takashima, Kazuko Saeki
Health (Health) , 2013, DOI: 10.4236/health.2013.56A2010
Abstract:

To aim to inductively clarify the professional identity of occupational therapists who work in a clinical setting, the researchers interviewed the 22 occupational therapists who had a minimum of 5 years or more of practice in the field. The professional identities of the practicing occupational therapists were constructed by the following two core categories: “harmonizing with a client’s life and the characteristic of a client’s disability”, and “giving clients sovereignties as a mission of the occupational therapists”. The occupational therapist can carry the role of coordinator in an interdisciplinary team for the clients with disability by understanding them. This is achieved based on the core category called “giving clients sovereignties as a mission of the occupational therapists”. Furthermore, in order to achieve the clients’ sovereignties, the occupational therapist can be an operational unit by planning practical strategies and practicing them based on the core category called “harmonizing with a client’s life and the characteristic of a client’s disability”. The fact is often difficult for these clients that they are concerned with how he/she lived actively. It is through unique ways of contributing for the clients in a team of professionals that the occupational therapists try to understand the clients not as “patients” but as “human beings”, and try to harmonize with their life and the characteristics of their disability, then try to support and empower them to reach a stage in which they have the sovereignties of their lives.

Reasons for the Creation of New Social Networks by the Elderly after Relocation  [PDF]
Yoshiko Kudo, Kazuko Saeki
Health (Health) , 2013, DOI: 10.4236/health.2013.512A005
Abstract:

It is important for the relocated elderly to create social networks within their new environment for their lives and their health. This research examined the reasons why the relocated elderly create social networks in the neighborhood. The research subject area is one snowfall town in Hokkaido, Japan. The subjects are 20 elderly people, who have been relocated to the town. The public health nurses individually conducted an interview and broke down the verbatim records into qualitative descriptions. The subjects ranged from 68 to 94 years old. Reasons why the elderly create social networks in their neighborhoods are to make their lives easier, to prepare for emergencies, to get rid of their loneliness, and to enjoy their lives. Community health providers should understand the need for neighboring social networks based on the elderly people’s condition, and support and create new networks in their community depending on their situations.

International Journal of Hypertension , 2010, DOI: 10.4061/2010/832821
Abstract: Hypertension, diabetes mellitus (especially type 2 diabetes mellitus), metabolic syndrome and obesity are rapidly growingpublic health problems. Sympathetic nerve activation is observed in obesity, hypertension and diabetes mellitus, which have strong genetic as well as environmental determinants. Reduced energy expenditure and resting metabolic rate are predictive of weightgain, and the sympathetic nervous system participates in regulating energy balance through thermogenesis. The thermogenic effects of catecholamines in obesity have been mainly mediated via the 2- and 3-adrenergic receptors in humans. Further, 2-adrenoceptors importantly influence vascular reactivity and may regulate blood pressure. Genetic polymorphistns of the -adrenoceptor gene have been shown to alter the function of several adrenoceptor subtypes and thus to modify the response to catecholamine. 2-adrenoceptor polymorphisms (Arg16Gly, Gln27Glu, and Thr164Ile) have been studied in relation to hypertension. Genetic variations in the 3-adrenoceptor (i.e. Try64Arg variant) are also associated with both obesity and hypertension. However, the precise relationships of the polymorphisms of 2- and 3-adrenoceptor genes with sympathetic nervous system activity, hypertension, and metabolic syndrome have not been fully clarified. This paper will discuss the current topics involving the influence of the sympathetic nervous system and 2- and 3- adrenoceptor polymorphisms in hypertension and metabolic syndrome.

Introduction Obesity, hypertension, and metabolic syndrome (type 2 diabetes mellitus) are major and growing health problems and are known as high-risk factors for subsequent cardiovascular and renal complications [1–3]. Obesity, hypertension, diabetes, and metabolic syndrome are intimately associated [4–6], and sympathetic nervous activation is frequently observed in those conditions. Thus, sympathetic nerve activation may play a major role in the onset and development of hypertension, obesity, and metabolic syndrome (diabetes mellitus) as well as cardiovascular complications in patients with hypertension, diabetes and obesity [2, 7]. The sympathetic nervous system plays an important role in the regulation of energy expenditure. Reduced energy expenditure and resting metabolic rate are predictive of weight gain (obesity). The sympathetic nervous system participates in regulating energy balance through thermogenesis [8]. A large part of the sympathetic nervous system-mediated energy expenditure takes place in skeletal muscle, via the coupling of catecholamines with β2-adrenoceptors.
Liaison conference for adolescent psychosomatic disease in pediatric ward  [PDF]
Takuji Inagaki, Rei Wake, Kazuko Kishi
Open Journal of Psychiatry (OJPsych) , 2012, DOI: 10.4236/ojpsych.2012.21006
Abstract: We held the liaison case conferences for two adolescent cases with psychosomatic disease in the pediatric ward to understand the patient's emotional problems and family situations, and to discuss how approach their psychological problems. We considered that the liaison conference played a useful role in both the clinical diagnosis and treatment. Furthermore, the liaison conference was useful for reducing the staff’s anxieties and for contributing to have a proper understanding for the disease. We suggest that a liaison conference should be implemented in pediatric units, for pediatric patients with emotional and behavioral problems.

Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2012, DOI: 10.4236/jcdsa.2012.22013
Abstract: Anogenital granulomatosis (AGG) is a rare chronic idiopathic disorder presenting as a painless swelling of the vulva, labia, penis, and/or anogenital area. Some AGG cases have been diagnosed along with Crohn’s disease (CD). We report a case of AGG that led to diagnosis of underlying CD, namely Cutaneous Crohn’s disease (CCD). We guess that CCD appeared in the anogenital region is equal to AGG with CD.
Development of a Social Activities Scale for Community-Dwelling Older Men Requiring Support in Japan  [PDF]
Michiyo Hirano, Kazuko Saeki, Izumi Ueda
Health (Health) , 2018, DOI: 10.4236/health.2017.101001
Abstract: Aim: We developed a scale to measure the social activities of community-dwelling older men requiring support. Methods: The participants were a group of 134 men, ≥65 years old, who required support and were living in Hokkaido, Japan. An anonymous questionnaire was administered through individual interviews. Valid responses were obtained from 121/134 interviewees. The construct validity of the resulting scale was assessed by exploratory factor analysis (EFA). Criterion-related validity was tested with Spearman’s rank correlation test based on the Social Activities Index for Elderly People (SAI-E). Reliability was assessed by Cronbach’s alpha. Results: A Social Activities Scale for Community-dwelling Older Men Requiring Support (SASOMS) scale was created, comprised of the following three subscales: daily interactions with familiar people; intimate relationships with family members; and interactions with others through activity programs (e.g., exercise, games, recreation, etc.). The created SASOMS scale correlated with the SAI-E (r = 0.557), and its criterion-related validity was confirmed. The alpha coefficient of the new scale was 0.791, and its internal consistency was confirmed. Conclusions: The reliability and validity of the developed SASOMS scale was confirmed, demonstrating that it can be used to assess social activities specifically in older men requiring support. Our results suggest that the scale can be used effectively by care providers who support older men requiring care. The usability of the SASOMS should continue to be improved, and it is necessary to verify its validity in longitudinal studies.
Fever screening during the influenza (H1N1-2009) pandemic at Narita International Airport, Japan

Abstract: Two datasets were collected at Narita International Airport during the 2009 pandemic. The first contained confirmed influenza cases (n = 16) whose diagnosis took place at the airport during the early stages of the pandemic, and the second contained a selected and suspected fraction of passengers (self-reported or detected by an infrared thermoscanner; n = 1,049) screened from September 2009 to January 2010. The sensitivity of fever (38.0°C) for detecting H1N1-2009 was estimated, and the diagnostic performances of the infrared thermoscanners in detecting hyperthermia at cut-off levels of 37.5°C, 38.0°C and 38.5°C were also estimated.The sensitivity of fever for detecting H1N1-2009 cases upon arrival was estimated to be 22.2% (95% confidence interval: 0, 55.6) among nine confirmed H1N1-2009 cases, and 55.6% of the H1N1-2009 cases were under antipyretic medications upon arrival. The sensitivity and specificity of the infrared thermoscanners in detecting hyperthermia ranged from 50.8-70.4% and 63.6-81.7%, respectively. The positive predictive value appeared to be as low as 37.3-68.0%.The sensitivity of entry screening is a product of the sensitivity of fever for detecting influenza cases and the sensitivity of the infrared thermoscanners in detecting fever. Given the additional presence of confounding factors and unrestricted medications among passengers, reliance on fever alone is unlikely to be feasible as an entry screening measure.The rapid international spread of severe acute respiratory syndrome (SARS) from 2002 to 2003 led countries around the world to extensively assess the entry screening measures at their international borders as one of the countermeasures to prevent the global spread of infectious diseases [1,2]. Pandemic influenza has been one of the most important subjects for entry screening [3]. Including an analysis of the historical records of maritime quarantine during the 1918-1919 influenza pandemic [4], many scientific discussions concerning the sci

Graziano, Kazuko Uchikawa;
Revista da Escola de Enfermagem da USP , 2002, DOI: 10.1590/S0080-62342002000300007
Abstract: the descriptions of the part i of this study showed that paraformaldehyde tablets in environmental conditions was used in a brazilian reality as the inadequate choosing way for most of the researched institutions. this articles shows how this chemical agent is used outstanding problems as the lack of a theoretical base and process validation compromiting, this way, the safety of the sterilization. the "sterilization" conditions of most of the institutions didn't include temperature, increment of the relative humidity and didn't make the adapted quantification of the tablets. it was observed that the researched institutions don't have based parameters that guide the reutilization of a same group of paraformaldehyde tablets in the sterilization processes. the use of individual protection equipment is quite valued in handle of this chemical agent.
