When taught the precise definition of ${\pi}$, students may be simply asked to memorize its approximate value without developing a rigorous understanding of the underlying reason of why it is a constant. Measuring the circumferences and diameters of various circles and calculating their ratios might just represent an attempt to verify that ${\pi}$ has an approximate value of 3.14, and will not necessarily result in an adequate understanding about the constant nor formally proves that it is a constant. In this study, we aim to investigate prospective teachers' conceptual understanding of ${\pi}$, and as a constant and whether they can provide a proof of its constant property. The findings show that prospective teachers lack a holistic understanding of the constant nature of ${\pi}$, and reveal how they teach students about this property in an inappropriate approach through a proving activity. We conclude our findings with a suggestion on how to improve the situation.

This study explores interpretations of grandmothers' experiences rearing their grandchildren. For this study, 13 participants provided in-depth interview data, which was analyzed according to Spradely's ethnographic method. Based on the pattern of interpretations, nine concepts were classified into three categories: (i) repentance (compulsive decisions, passivity of the childrearing activity, non-compensation); (ii) sorrow (restrictions on everyday life, renunciation of occupational careers, worsened health); and (iii) satisfaction (decreased isolation in old age, proof of existence for their children, intimacy development with their grandchild). The results of this study show that grandmothers have a higher appreciation for the benefits of relational compensation than for personal cost. Some practical implications are suggested to improve family welfare.

This paper proposes a wearable user interface intended for kids and parents using WearOS smartwatches. We first review what constitutes a kids smartwatch and then design UI components for watchfaces to be used by kids and parents. Different UI components ranging from activity, education, voice search, app usage, video, location, health, and quick dial are described. These components are either implemented as complications or on watchfaces and may require on-device standalone function, cross-device communication, and external database. We introduce a theme-based amusing UI for kids whereas simple and easily accessible components are recommended to parents' watchface. To illustrate use cases, we present 3 scenarios for enhancing communication between parents and child. To show feasibility and potential of our approach, we implement our proof-of-concept using commercial smartwatches, smartphones, and external cloud database. Furthermore, performance of checking app usages on different devices are presented, followed by discussion on limitations and future work.

Though the debate of the establishment time, place and characteristic of the first fisheries cooperatives in Korea has been existed, it is clear that they had been established in the neighborhood of Tongyeong during the period of Japanese colonial rule. But the objective, motive and historical background of the first fisheries cooperatives are still slightly vague. To explain and explore that of fisheries cooperatives, over 1,000 articles of media, about 100 document of the Japanese government-general of Korea and the annals of the Joseon dynasty, many of research paper and others were included and refined. Through the result of that process, three core factors were founded that affect both the emergence of fisheries cooperatives and relationship of the them. The first one is about the royal family's fishing area where in the neighborhood of Tongyeong. The next one is Kentaro Kashii who was called king or devil of the Korean fisheries industry and the last one is fishermen and their organizations including fisheries cooperatives. Some of the above and the fishing rights conflict that make a guidance for understanding them has not been clearly mentioned. The result of this study shows that the birth of the first fisheries cooperatives were caused by not only the Japanese government-general of Korea but mainly Korean fishermen's voluntary activity and free will against fishing rights conflict between them. And both of the first fisheries cooperatives had somewhat difference in their constitution of organization and their characteristics but it was a tragic irony that the more exploitation and despoliation were conducted by Japanese government-general and Japanese capitalist the more movement and activity of Korean were frequently and severely occurred. Even though the findings and results of this study would be a proof and helpful material for understanding the establishment and their activity of fisheries cooperatives in Tongyeong, more research and contribution would be need by members of fisheries academic and business world.

Endocrine-disrupting chemicals (EDCs) are compounds that disturb hormonal homeostasis by binding to receptors. EDCs are metabolized through hepatic enzymes, causing altered transcriptional activities of hormone receptors, and thus necessitating the exploration of the potential endocrine-disrupting activities of EDC-derived metabolites. Accordingly, we have developed an integrative workflow for evaluating the post-metabolic activity of potential hazardous compounds. The system facilitates the identification of metabolites that exert hormonal disruption through the integrative application of an MS/MS similarity network and predictive biotransformation based on known hepatic enzymatic reactions. As proof-of-concept, the transcriptional activities of 13 chemicals were evaluated by applying the in vitro metabolic module (S9 fraction). Identified among the tested chemicals were three thyroid hormone receptor (THR) agonistic compounds that showed increased transcriptional activities after phase I+II reactions (T3, 309.1 ± 17.3%; DITPA, 30.7 ± 1.8%; GC-1, 160.6 ± 8.6% to the corresponding parents). The metabolic profiles of these three compounds showed common biotransformation patterns, particularly in the phase II reactions (glucuronide conjugation, sulfation, GSH conjugation, and amino acid conjugation). Data-dependent exploration based on molecular network analysis of T3 profiles revealed that lipids and lipid-like molecules were the most enriched biotransformants. The subsequent subnetwork analysis proposed 14 additional features, including T4 in addition to 9 metabolized compounds that were annotated by prediction system based on possible hepatic enzymatic reaction. The other 10 THR agonistic negative compounds showed unique biotransformation patterns according to structural commonality, which corresponded to previous in vivo studies. Our evaluation system demonstrated highly predictive and accurate performance in determining the potential thyroid-disrupting activity of EDC-derived metabolites and for proposing novel biotransformants.

The healing properties of medicinal maggots (larval stage of Lucilia sericata) are widely used in the chirurgical debridement of non-healing wounds including diabetic foot ulcers, venous and pressure ulcers, where classical approaches have failed. Several kinds of wounds are prone to complications coming out of a specific wound bed environment. There are multi-resistant bacterial species present, their pathogenic impact is multiplied by their ability to form a biofilm. Moreover, immunological events in chronic wounds differ from those in acute wounds. Non-healing wounds are cycled in the early inflammation phase with increased levels of inflammation attributes like inflammation cytokines and matrix metalloproteinases produced by inflammation phase cells. Application of larval therapy promotes progress in the healing process to the next stages involving tissue granulation and re-epithelisation. Larval debridement is an effective method of cleaning the wound of cell debris, necrotic tissue and bacterial load. This happens in a mechanical and biological manner, but the whole complex mechanism of the maggot healing activity is still not fully elucidated. Centuries of clinical practice brings noticeable proof of the maggots' beneficial effect in wound healing management. This long history led to the investigation of the bioactive components of the larval body and its extracts in vitro. We introduce a review which describes the immunomodulation impact of maggot body components on the cellular and molecular levels of the wound healing process.

본 연구는 학교 수학에서 추론 지도의 수준을 보다 상세히 구분해 보고자 한 것이다. 수학의 특징으로부터, 대상에서 분리된 순수한 형식적 관점은 새로운 지식의 창안에서 한계를 지닌다는 점을 알 수 있으며, 수학교육에서도 이를 반영할 필요가 있다고 본다. 이런 점에서 귀납 추론과 형식적 연역 추론의 매개 단계로서 구체적 조작이나 감각 경험과 관련된 직관적 증명의 수준을 설정하는 것이 적절할 것으로 생각되며, 이 수준의 핵심적인 활동은 경험으로부터 일반성을 통찰하는 것이다. 이 수준은 낮은 수준의 귀납 추론보다는 대상과 분리되며 보다 형식적인 논리의 개입을 필요로 하는 과정에 있다. 이와 같이 보다 점진적으로 대상으로부터 분리되고 형식적 논리를 학습할 수 있도록 추론 지도 수준을 구분하고, 이에 따라 수학적 추론을 지도하는 것이 필요할 것이다.
