Identifying Characteristics of the Agile Development Process That Impact User Satisfaction

The purpose of this study is to identify the characteristics of Agile development processes that impact user satisfaction. We used user reviews of OSS smartphone apps and various data from version control systems to examine the relationships, especially time-series correlations, between user satisfaction and development metrics that are expected to be related to user satisfaction. Although no metrics conclusively indicate an improved user satisfaction, motivation of the development team, the ability to set appropriate work units, the appropriateness of work rules, and the improvement of code maintainability should be considered as they are correlated with improved user satisfaction. In contrast, changes in the release frequency and workload are not correlated

Lifestyle changes of Japanese people on overseas assignment in Michigan, USA

<p>Abstract</p> <p>Background</p> <p>Temporary work assignments in the United States (US) are widely considered to have negative health outcomes on Asians mostly due to adverse changes in diet and exercise, though there is little research on this phenomenon. This study investigated the impact of lifestyle changes on the biological and psychological health and health behaviours of Japanese people on temporary assignments in the US.</p> <p>Methods</p> <p>In this cross sectional survey, we distributed a 38 item self-administered questionnaire addressing health habits, mental health function, lifestyle changes and dietary habits to adult Japanese patients presenting for general physicals at a family medicine clinic serving Japanese patients. We conducted simple statistics and regression analysis between length of stay and other health outcomes to determine whether length of residence in the US was predictive of negative lifestyle changes.</p> <p>Results</p> <p>Most participants reported increased caloric intake, weight gain, and less exercise. They also reported increased time with family. More women than men reported physical symptoms and anxiety related to stress. Smoking and alcohol intake were essentially unchanged. No associations were identified between length of residence in the US and health lifestyle habits or other health outcomes.</p> <p>Conclusion</p> <p>Negative lifestyle changes occur in diet and exercise for overseas Japanese people, but a positive change in increased family time was found. Women appear to be at a greater risk for somatic disorders than men. As duration of stay does not appear predictive of adverse changes, clinicians should advise patients going abroad of these risks regardless of the term of the work assignment.</p

Epitope Analysis of Cerebrospinal Fluid IgG in Japanese Multiple Sclerosis Patients Using Phage Display Method

To investigate the antigen recognized by cerebrospinal fluid (CSF) high affinity IgG in patients with multiple sclerosis (MS), the phage display method was applied to the CSF from 15 MS and 10 control patients. Peptide sequences recognized by MS and control CSF IgG were individual specific, and no common motif was found. Peptide sequences frequently showed homology to various kinds of amino acid sequences of ubiquitous viruses such as epstein barr virus (EBV) and herpes simplex virus (HSV), although the frequency was not specific to MS patients. MS CSF IgG may recognize various types of ubiquitous viral antigen and may be increased by a bystander response

Evaluation of a communication skills seminar for students in a Japanese medical school: a non-randomized controlled study

BACKGROUND: Little data exist for the effectiveness of communication skills teaching for medical students in non-English speaking countries. We conducted a non-randomized controlled study to examine if a short intensive seminar for Japanese medical students had any impact on communication skills with patients. METHODS: Throughout the academic year 2001–2002, a total of 105 fifth-year students (18 groups of 5 to 7 students) participated, one group at a time, in a two-day, small group seminar on medical interviewing. Half way through the year, a five-station objective structured clinical examination (OSCE) was conducted for all fifth-year students. We videotaped all the students' interaction with a standardized patient in one OSCE station that was focused on communication skills. Two independent observers rated the videotapes of 50 students who had attended the seminar and 47 who had not. Sixteen core communication skills were measured. Disagreements between raters were resolved by a third observer's rating. RESULTS: There was a statistically significant difference in proportions of students who were judged as 'acceptable' in one particular skill related to understanding patient's perspectives: asking how the illness or problems affected the patient's life, (53% in the experimental group and 30% in the control group, p = .02). No differences were observed in the other 15 core communication skills, although there was a trend for improvement in the skill for asking the patient's ideas about the illness or problems (60% vs. 40%, p = .054) and one of the relationship building skills; being attentive and empathic nonverbally (87% vs. 72%, p = .064). CONCLUSION: The results of this study suggest that a short, intensive small group seminar for Japanese medical students may have had a short-term impact on specific communication skills, pertaining to understanding patient's perspectives

Prevention of type 2 diabetes in a primary healthcare setting: Three-year results of lifestyle intervention in Japanese subjects with impaired glucose tolerance

<p>Abstract</p> <p>Background</p> <p>A randomized control trial was performed to test whether a lifestyle intervention program, carried out in a primary healthcare setting using existing resources, can reduce the incidence of type 2 diabetes in Japanese with impaired glucose tolerance (IGT). The results of 3 years' intervention are summarized.</p> <p>Methods</p> <p>Through health checkups in communities and workplaces, 304 middle-aged IGT subjects with a mean body mass index (BMI) of 24.5 kg/m²were recruited and randomized to the intervention group or control group. The lifestyle intervention was carried out for 3 years by public health nurses using the curriculum and educational materials provided by the study group.</p> <p>Results</p> <p>After 1 year, the intervention had significantly improved body weight (-1.5 ± 0.7 vs. -0.7 ± 2.5 kg in the control; p = 0.023) and daily non-exercise leisure time energy expenditure (25 ± 113 vs. -3 ± 98 kcal; p = 0.045). Insulin sensitivity assessed by the Matsuda index was improved by the intervention during the 3 years. The 3-year cumulative incidence tended to be lower in the intervention group (14.8% vs.8.2%, log-rank test: p = 0.097). In a sub-analysis for the subjects with a BMI > 22.5 kg/m², a significant reduction in the cumulative incidence was found (p = 0.027).</p> <p>Conclusions</p> <p>The present lifestyle intervention program using existing healthcare resources is beneficial in preventing diabetes in Japanese with IGT. This has important implications for primary healthcare-based diabetes prevention.</p> <p>Trial registration number</p> <p><b>UMIN000003136</b></p
