  • The purpose of this paper is to investigate the determinants of new product diffusion. We seek to document and explain systematic features of product diffusion. In this essay, we examine the well-documented empirical regularity that the speed of diffusion has accelerated during the twentieth century. The empirical results show that the main source of acceleration are faster declines in prices. Faster price declines make the product affordable to more consumers within a given period of time. Based on theories of intertemporal price discrimination and learning-by-doing, the association between the speed of adoption and the speed of price decline was explained. Faster price declines are attributed to several product characteristics as well as changes in income distribution. Above all, the introduction of consumer electronic products in more recent years can be regarded as the most important factor in accelerating price declines. Consumer electronic products are technologically different from non-electronic goods, in that semiconductors are important components. As the price of semiconductors has dropped rapidly, the falling production costs can be rapidly incorporated to the price of consumer electronic goods. Furthermore, most of the recently introduced consumer electronic products have network externalities, and many products with network externalities require complementary products. A complementary product becomes more readily or cheaply available as more people have the main product. One major difference between previous studies and this study is that the former focuses only on the factors that operate directly on the speed of adoption, while this study incorporated factors that work through price changes as well as the factors that work directly on the speed of adoption.

  • Background: Health, safety, and well-being (HSW) at work represent important values in themselves. It seems, however, that other values can contribute to HSW. This is to some extent reflected in the scientific literature in the attention paid to values like trust or justice. However, an overview of what values are important for HSW was not available. Our central research question was: what organizational values are supportive of health, safety, and well-being at work? Methods: The literature was explored via the snowball approach to identify values and value-laden factors that support HSW. Twenty-nine factors were identified as relevant, including synonyms. In the next step, these were clustered around seven core values. Finally, these core values were structured into three main clusters. Results: The first value cluster is characterized by a positive attitude toward people and their "being"; it comprises the core values of interconnectedness, participation, and trust. The second value cluster is relevant for the organizational and individual "doing", for actions planned or undertaken, and comprises justice and responsibility. The third value cluster is relevant for "becoming" and is characterized by the alignment of personal and organizational development; it comprises the values of growth and resilience. Conclusion: The three clusters of core values identified can be regarded as "basic value assumptions" that underlie both organizational culture and prevention culture. The core values identified form a natural and perhaps necessary aspect of a prevention culture, complementary to the focus on rational and informed behavior when dealing with HSW risks.

  • In this paper, simple but very effective techniques to suppress subthreshold hump effect for high-voltage (HV) complementary metal-oxide-semiconductor (CMOS) technology are presented. Two methods are proposed to suppress subthreshold hump effect using a simple layout modification approach. First, the uniform gate oxide method is based on the concept of an H-shaped gate layout design. Second, the gate work function control method is accomplished by local ion implantation. For our experiments, $0.18{\mu}m$ 20 V class HV CMOS technology is applied for HV MOSFETs fabrication. From the measurements, both proposed methods are very effective for elimination of the inverse narrow width effect (INWE) as well as the subthreshold hump.

  • Traditional healers in Ghana are so near to the health needs and aspirations of the majority of people who live mostly in the rural areas, yet have been excluded from the formal health care delivery system. Medical systems in Africa and around the globe have broad-ranging ties to the cosmology and the way of life of a people. However, in Ghana, colonialism and external orientation have had a negative influence on Traditional Medicine (TRM). Thus, in Ghana, Traditional healers can be described as a marginalized group and yet their roles in effective delivery of primary and mental health care cannot be overemphasized. This paper elucidates advocacy work toward medical pluralism in Ghana. First, the influence of colonialism on TRM is briefly examined, followed by highlights on advocacy work intended to include TRM in the health care system. Based on "small wins", challenges, successes, and prospects of our advocacy are discussed.

  • The purpose of this study is to find Healing elements in the late work of Frank Lloyd Wright. Healing elements are mainly composed of physical, social and psychological functions, which are clearly reflected in holistic attitude and intuition in his Organic theory of Architecture. Late works of Wright since 1935 show particularly shapes of triangle and circle creating the emotional images associated with Hope and Infinity. His image-oriented design attitude is thought to be strongly related to the pursuit of Utopian ideal which means peaceful condition. He regarded it as the consequence of integrity and control, which could be thought as condition of Healing environment. Refuge and Prospect can be complementary elements of spatial expression representing peaceful and dynamic condition of the Nature itself. Five works selected in this case study have unique design ideas related to the function and image of Healing environment interpreted by the criteria of Refuge and Prospect.

  • As pointed out in the OECD BEMUSE Program, when a high computation time is taken to obtain the relevant output values of a complex physical model (or code), the number of statistical samples that must be evaluated through it is a critical factor for the sampling-based uncertainty analysis. Two alternative methods have been utilized to avoid the problem associated with the size of these statistical samples: one is based on Wilks' formula, which is based on simple random sampling, and the other is based on the conventional nonlinear regression approach. While both approaches provide a useful means for drawing conclusions on the resultant uncertainty with a limited number of code runs, there are also some unique corresponding limitations. For example, a conclusion based on the Wilks' formula can be highly affected by the sampled values themselves, while the conventional regression approach requires an a priori estimate on the functional forms of a regression model. The main objective of this paper is to assess the feasibility of the ACE-RSM approach as a complementary method to the Wilks' formula and the conventional regression-based uncertainty analysis. This feasibility was assessed through a practical application of the ACE-RSM approach to the LOFT L2-5 LBLOCA PCT uncertainty analysis, which was implemented as a part of the OECD BEMUSE Phase III program.

  • Background: The objective of this article is to make some analysis on the process of work and accidents occurring in slaughterhouses, evidenced in the Brazilian documentary film called Flesh and Bone. As such, it was necessary to discuss an alternative theoretical concept in relation to theories about health and safety at work. This alternative discussion focuses on the concepts of biopower and biopolitics. Methods: The use of audiovisual elements in research is not new, and there is already a branch of studies with methodological and epistemological variations. The Brazilian documentary Flesh and Bone was the basis for the research. The analysis of this documentary will be carried out from two complementary perspectives: "textual analysis" and "discourse analysis." Results: Flesh and Bone presents problems related to health and safety at work in slaughterhouses because of the constant exposure of workers to knives, saws, and other sharp instruments in the workplace. The results show that in favor of higher production levels, increased overseas market sales, and stricter quality controls, some manufacturers resort to various practices that often result in serious injuries, disposal, and health damages to workers. Conclusion: Flesh and Bone, by itself, makes this explicit in the form of denunciation based on the situation of these workers. What it does not make clear is that, in the context of biopolitics, the actions aimed at solving these problems or even reducing the negative impacts for this group of workers, are not efficient enough to change such practices.

  • 본 논문에서는 complementary split ring resonator(CSRR)을 이용하여 마이크로파 대역에서 비침습적으로 포도당 수용액과 염화나트륨 수용액을 구별하였다. 개방형 동축 프로브로 측정한 두 수용액의 전기적 특성을 기반으로 구별이 유리한 주파수에서 동작하는 CSRR을 설계, 제작하였다. 그리고 공진기의 전기장이 강하게 형성되는 부분에 수용액을 집중시키기 위해 PDMS mold를 제작하였고, 라미네이트 필름으로 수용액과 공진기의 접촉을 방지하였다. 두 수용액의 농도는 인체 혈당 농도 범위인 400 mg/dL까지 100 mg/dL 단위로 나누었고, $50{\mu}L$의 수용액으로 실험하였다. 공진 주파수에서 포도당 수용액과 염화나트륨 수용액의 투과계수($S_{21}$)를 측정한 결과, 100 mg/dL 농도 변화 대비 각각 -0.06 dB, 0.14 dB 변하는 것을 확인하였고, 상반된 경향을 통해 두 수용액의 농도에 따른 $S_{21}$의 변화를 선택적으로 구별하였다.

  • Background: With global changes in the current state of work and employment, the role of health-adverse psychosocial work environments has received increasing attention in developed as well as in rapidly developing countries. Thus, there is a need to apply valid measurement tools for monitoring and preventive purposes. This study aims to examine the factorial structure and psychometric properties of the Persian version of the effort-reward imbalance (ERI) questionnaire, assessing one of the internationally leading concepts of stressful work. Methods: This descriptive cross-sectional study of a random sample of 202 white collar employees in an industrial company in Iran analyzes the ERI scales by exploratory and confirmatory factor analysis. Moreover, aspects of construct and criterion validity are tested. To this end, correlations of ERI scales with subscales of organizational injustice, a complementary work stress model, and also the correlations of ERI scales with a questionnaire assessing psychosomatic symptoms are performed. Results: Internal consistency of the three ERI scales was satisfactoryy (Cronbach ${\alpha}$ effort: 0.76, reward: 0.79, overcommitment: 0.75). Fit indices of confirmatory factor analsis pointed to an adequate representation of the theoretical construct (e.g., adjusted goodness of fit index (AGFI): 0.73, goodness of fit index (GFI): 0.78). Negative correlations with subscales of organizational injustice supported the notion of construct validity of the ERI scales, and positive correlations of ERI scales with psychosomatic symptoms indicated preliminary criterion validity. Conclusion: The Persian version of the ERI questionnaire has acceptable psychometric properties and can be used as a valid instrument in research on this topic.
