Sustainable Shoe Design with a Single Material

People tend to throw away a shoe rather than repair it for further use. This means more and more shoes are thrown away, and since a shoe is made out of many kinds of materials that are all glued or stitched together, it is difficult to recycle or reuse the shoe. Additionally, there is a symbolic relation between the land and shoe; a shoe is the product that connects people to the ground. It is ironic that a shoe, which provides the connection, has a negative effect on the land. If we wear a shoe longer, we can reduce the number of discarded shoes and have a positive effect on the environment. I want to design a sustainable shoe by making it last longer and making it recyclable with replaceable parts, so users can simply change a part when it wears out or when they want to try a different style and function. It can be made with an industrial quality material. At the end of their serviceable life, shoes can be easily recycled or reused. The shoes can be used to make other shoes and other products

Is Scissoring a Metaphor for Disconnecting a Relationship?

A great deal of attention has surrounded the role of embodied cognition in human judgments; however, it has received very little research attention, especially in the marketing field. This research is based on the idea that the act of cutting can activate perceptions of severing relationships, as well as eliciting a sense of independence. Study 1 showed that consumers are less likely to adopt a close friend’s opinion when they engage in the act of cutting an object with scissors. Study 2 demonstrated that people are less likely to trust the reviews of online communities while cutting a piece of string with scissors. These lowered intentions to adopt others’ opinions appeared to be mediated by increased psychological distances between the self and the information provider. In other words, people who engage in the act of scissoring unconsciously weaken or disconnect themselves from the information providers, thereby choosing not to adopt others’ opinions. This research identifies the link between the physical activity of cutting and the mental disconnection concerning social relationships. The results provide implications in setting up an integrative framework of the consumer decision-making process involving embodied cognition.      

Secondary Use Provisions in the European Health Data Space Proposal and Policy Recommendations for Korea

Objectives This article explores the secondary use provisions of the European Health Data Space (EHDS), proposed by the European Commission in May 2022, and offers policy recommendations for South Korea. Methods The authors analyzed the texts of the EHDS proposal and other documents published by the European Union, as well as surveyed the relevant literature. Results The EHDS proposal seeks to create new patient rights over electronic health data collected and used for primary care; and establish a data sharing system for the re-use of electronic health data for secondary purposes, including research, the provision of personalized healthcare, and developing healthcare artificial intelligence (AI) applications. These provisions envisage requiring both private and public data holders to share certain types of electronic health data on a mandatory basis with third parties. New government bodies, called health data access bodies, would review data access applications and issue data permits. Conclusions The overarching aim of the EHDS proposal is to make electronic health data, which are currently held in the hands of a small number of organizations, available for re-use by third parties to stimulate innovation and research. While it will be very challenging for South Korea to adopt a similar scheme and require private entities to share their proprietary data with third parties, the South Korean government should consider making at least health data collected through publicly funded research more readily available for secondary use

Continued fractions and the density of graphs of some functions

We consider some simple periodic functions on the field of rational numbers with values in $\mathbb{Q}/\mathbb{Z}$ which are defined in terms of lowest-term-expression of rational numbers. We prove the density of graphs of these functions by constructing explicitly points on the graphs close to a given point using continued fractions

Endometrioid Adenocarcinoma in Urethrovaginal Septum: A Diagnostic Pitfall

Primary endometrioid adenocarcinoma developed at urethrovaginal septum has not been reported. A 61-yr-old woman presented with recurrent urinary tract infection. She had received hormone replacement treatment with estrogen and progesterone for 5 yr. A pinpoint ulceration at slightly elevated anterior vaginal wall was found and biopsy revealed endometrioid adenocarcinoma. Magnetic resonance imaging showed the 4.3 cm sized mass in urethrovaginal septum. She has undergone anterior pelvic exenteration, pelvic lymph node dissection, and urostomy with ileal conduit. Microscopic finding of the pathology revealed endometrioid adenocarcinoma. Co-existence of endometriosis was not identified. Tumor at urethrovaginal septum was difficult to be detected till growing to be bulky, because of vaginal axis, misunderstanding of the tumor as symphysis pubis, no definitive symptom, and its rarity. This is the first reported case of extraovarian endometrioid adenocarcinoma developed at the urethrovaginal septum. Understanding normal functional anatomy and meticulous physical examination are essential to detect this rare tumor in the urethrovaginal septum
