Development of the workflow kine systems for support on KAIZEN

In this paper, we introduce the new workflow line system consisted of the location and image recording, which led to the acquisition of workflow information and the analysis display. From the results of workflow line investigation, we considered the anticipated effects and the problems on KAIZEN. Workflow line information included the location information and action contents information. These technologies suggest the viewpoints to help improvement, for example, exclusion of useless movement, the redesign of layout and the review of work procedure. Manufacturing factory, it was clear that there was much movement from the standard operation place and accumulation residence time. The following was shown as a result of this investigation, to be concrete, the efficient layout was suggested by this system. In the case of the hospital, similarly, it is pointed out that the workflow has the problem of layout and setup operations based on the effective movement pattern of the experts. This system could adapt to routine work, including as well as non-routine work. By the development of this system which can fit and adapt to industrial diversification, more effective "visual management" (visualization of work) is expected in the future.     

Study on workloads of human care worker with the introduction of IT system - the characteristics of work loads by observational research and the suggestions for KAIZEN

The purpose of this study was to clarify the characteristic of workloads on human care worker with the introduction of IT system, and suggested the support measures for KAIZEN in Japan. The investigation method is workflow line and hearing with a focus on work observation. The objects were 8 human care workers of the acute hospital that introduced an electronic system. By the introduction of the electronic chart, the nurse station sojourn time decreased, sickroom sojourn time increased, and time about direct nursing care to a patient increased. In addition, access to patient information became easy, and the offer of the health care service based on correct information came to be possible in real time. By The point of workflow line, it was effect that moving lengths decreased in order to install the electronic chart in patients' rooms. Though, it was a problem that it hasn't formed where to place the instruments such as sphygmomanometer, clinical thermometer and others.     

On Combinatorial Approximation of Covering 0-1 Integer Programs and Partial Set Cover

The problems dealt with in this paper are generalizations of the set cover problem, min{cx | Ax b, x {0,1}ⁿ}, where c Q₊ⁿ, A {0,1}^{m × n}, b 1. The covering 0-1 integer program is the one, in this formulation, with arbitrary nonnegative entries of A and b, while the partial set cover problem requires only m–K constrains (or more) in Ax b to be satisfied when integer K is additionall specified. While many approximation algorithms have been recently developed for these problems and their special cases, using computationally rather expensive (albeit polynomial) LP-rounding (or SDP-rounding), we present a more efficient purely combinatorial algorithm and investigate its approximation capability for them. It will be shown that, when compared with the best performance known today and obtained by rounding methods, although its performance comes short in some special cases, it is at least equally good in general, extends for partial vertex cover, and improves for weighted multicover, partial set cover, and further generalizations.     

Relative Curvature Measure for Heteroscedastic or Non Normal Nonlinear Regression

The Bates–Watts relative curvature measure can assess the validity of the linearized approximation in nonlinear regression models. However, it is developed based on an ordinary nonlinear regression in which the observation is assumed to be homoscedastically and normally distributed. In this article, we extend the original Bates–Watts relative curvature measure to one that can be applicable to nonlinear regression with heteroscedastic or non normal data, based on the transformation-both-sides (TBS) approach. In pharmacokinetic models, a diagnostic use of their measures is illustrated. By means of a simulation experiment, the performance of the relative curvature measure for the TBS approach is evaluated.     

Person‐Environment Fit and Positive Youth Development in the Context of High School Gay–Straight Alliances

Drawing from a person‐environment fit framework, we identified profiles of youth in gay–straight alliances (GSAs) based on the extent to which they received information/resources, socializing/support, and advocacy opportunities in their GSAs and the extent to which this matched what they desired from their GSA along these three functions. Further, we examined profile differences in positive developmental competencies while accounting for community‐contextual factors. In a sample of 290 youth from 42 Massachusetts GSAs, latent profile analyses identified five subgroups. Overall, youth receiving less from their GSAs than they desired, particularly regarding opportunities for advocacy, reported lower levels of self‐reflection, bravery, civic engagement, and agency than youth who received information, socializing/support, and advocacy that matched or exceeded what they desired.     

Predicting the timing of maternal employment after birth among a low-income and ethnically diverse sample

Policy pressures in the USA to transition parents from public assistance to work and concerns about the effects of early maternal employment on children highlight the importance of studying predictors of the timing of postpartum maternal employment. Little attention has been given to postpartum employment patterns of low-income ethnic minorities and immigrants, whose working conditions and employment prospects are different from white, middle-class mothers. Using a sample of low-income Mexicans, Dominicans, and African-Americans (N = 310), we studied whether and when mothers start working the first year following childbirth, and what factors promote or delay postpartum employment. Using discrete-time survival analysis, we modeled the odds of working at each month and tested the influence of family context, mothers' work and family values and plans, maternity leave benefit, and instrumental support availability on the timing of employment. By 11 months, half of the mothers had started working. Having maternity leave, plans to work, childcare arrangements, and a strong work orientation increased the odds of working. Household earnings were related to postpartum employment, but this effect varied over time. For African-Americans, instrumental support availability predicted earlier returns to employment, whereas for Mexicans and Dominicans it related to later returns to employment.     

Unauthorized Status and Youth Development in the United States: Consensus Statement of the Society for Research on Adolescence

In the United States, 5.3 million children and adolescents are growing up either with unauthorized status or with at least one parent who has that status. Until recently, little in the way of research has informed federal, state, and local policy debates related to unauthorized status (e.g., border enforcement, deportation, and a pathway to citizenship) although these issues have important implications for youth development. This statement is a brief summary of the research evidence on multiple domains of development that may be affected by the child or parent's unauthorized status. We also describe the contextual and psychological mechanisms that may link this status to developmental outcomes. We summarize a range of policies and practices that could reduce the developmental harm to children, youth, and their families stemming from this status. Finally, we conclude with recommendations for policy, practice, and research that are based on the evidence reviewed.     

Parents' Goals for Children: The Dynamic Coexistence of Individualism and Collectivism in Cultures and Individuals

Current scholarship on the cultural value systems of individualism and collectivism, and the associated developmental goals of autonomy and relatedness, has moved beyond grand divide theories to emphasize variation within individuals and cultures. We present a theoretical model on the dynamic coexistence of cultural value systems (at the macro level) and parents' developmental goals (at the micro level). We contend that cultural values and developmental goals that have largely been classified as polar opposites may be viewed as conflicting, additive, or functionally dependent. Parents may view the developmental goal of autonomy as interfering with the goal of relatedness (and vice versa); parents may endorse both autonomy and relatedness; and parents may consider the developmental goal of relatedness to be a path to the goal of autonomy and/or autonomy to be a path to relatedness. These forms of coexistence are themselves dynamic, changing across situations, developmental time, and in response to social, political, and economic contexts.
