모둠별 게임 변형을 통한 초등수학영재들의 수학적 정교화 과정 분석

성예원,송상헌 대한수학교육학회 2013 학교수학 Vol.15 No.3

본 연구는 초등수학영재들이 수학적 소재의 기존 게임을 변형하여 새로운 게임을 만들어 가는 동안 모둠내 토론 과정에서 드러나는 수학적 정교화 과정을 분석하고 이를 모델화한 것이다. 이를 위해 한 개의 지역공동영재학급에서 5주간의 수업을 진행하였으며, 특히 게임의 변형의 아이디어를 모둠별로 모아가는 수학적 정교화 과정을 모델로 구안하고자 하였다. 정교화 과정에서 수학적 경로와 수학외 경로가 상호작용을 하는 이중 경로의 모습을 띄었으며, 수학적(논리적) 근거에 따라 3가지의 수학적 경로(호의, 비호의, 중립)와 4가지의 수학외 경로(비일관성, 사회적 증거, 호감, 권위)으로 분석할 수 있었다. 이 과정에서 수시로 통찰이 일어났으며, 이 과정을 거쳐 수학적 규칙이 모둠에서 수렴되는 정교화의 모습을 볼 수 있었다. 이를 바탕으로 초등수학영재들이 모둠별로 게임을 변형하는 과정에서 보이는 수학적 정교화 과정을 분석하고 수학적 정교화 모델을 제안하였다. One area where research is especially needed is their elaboration process and how they elaborate their idea as a group in a mathematical board game re-creation project. In this research, this process was named ‘Mathematical Elaboration Process’. The purpose of this research is to understand how the gifted children elaborate their idea in a small group, and which idea can be chosen for a new board game when they are exposed to a project for making new mathematical board games using the what-if-not strategy. One of the gifted children’s classes was chosen in which there were twenty students, and the class was composed of four groups in an elementary school in Korea. The researcher presented a series of re-creation game projects to them during the course of five weeks. To interpret their process of elaborating, the communication of the gifted students was recorded and transcribed. Students' elaboration processes were constructed through the interaction of both the mathematical route and the non-mathematical route. In the mathematical route, there were three routes; favorable thoughts, unfavorable thoughts and a neutral route. Favorable thoughts was concluded as ‘Accepting’, unfavorable thoughts resulted in ‘Rejecting’, and finally, the neutral route lead to a ‘non-mathematical route’. Mainly, in a mathematical route, the reason of accepting the rule was mathematical thinking and logical reasons. The gifted children also show four categorized non-mathematical reactions when they re-created a mathematical board game; Inconsistency, Liking, Social Proof and Authority.

Diltiazem, vasopressin과 3-in-1 정맥영양의 물리적 배합적합성

방은숙,성예원,김승란,박지현,최수안 한국병원약사회 2018 病院藥師會誌 Vol.35 No.2

Background : The hospitalized patients requiring parenteral nutrition (PN) often need to receive intravenous medications as well, as noted in some cases. The Y-site administration is occasionally necessary, but some physicochemical incompatibilities can occur between the medications and PN. The absence of drug compatibility information with 3-in-1 parenteral nutrition admixture (PNA) has been problematic in this case. The infusion of a precipitate or destabilized emulsion can be harmful for the patients. Therefore, the aim of this study was to evaluate the physical compatibility of 2 selected drugs during a simulated Y-site injection and additive condition into a 3-in-1 PNA. Methods : 3-in-1 PNA (OMAFONE Inj 986 mL) were tested with two drugs (diltiazem, vasopressin). PNAs and drugs were mixed in 1:1(v/v) proportions and the compatibility was assessed at the time of mixing and after 1, 24, 48 and 72 hours. Chiefly, the assessment of potential precipitation and the emulsion stability was performed by a subvisual particle counting an, through visual examinations and a measurement of globule size distribution. Results : In all samples we did not observe changes on the visual examinations. It is noted that the oil droplet mean size changes over 1.5 μm are to exceed 2% in the Y-site samples of diltiazem and vasopressin within 24 hours. In particular, these samples of vasopressin did not disappear until after a 72 hours timeframe. However, the globule size distribution via a dynamic light scattering are maintained at 200-300 nm during the experimental period. Conclusions : The present study experiment noted the compatibility of 1 commercially available PNA and 2 medications. The extrapolation of compatibility data based on conditions applicable for other products is not recommended. It is noted that a different outcome can also be a result of differences in the methodology or interpretation of the results. Finally, we recommend that a filter is concerned primarily with the protection of patients from the effects of an infusion of particulates and chemical precipitates. The appropriate use of this complex therapy is able to maximize the clinical benefit while minimizing the potential risks for adverse events.

Purpose: There have been no clinical studies on the characteristics of parenteral nutrition (PN) for adult cancer inpatients in South Korea. The published evidence describing modern PN practices in these patients is also extremely limited. Therefore in this retrospective multicenter cross-sectional study, we aimed to investigate the PN support practice in hospitalized adult cancer patients. Methods: The study included adult cancer patients hospitalized in nine hospitals in South Korea and received PN, during the period from August 1st, 2017 to October 30th, 2017. We evaluated the relevant hospital-based PN practices in this group. Results: Among the 11,580 inpatient admissions during this period, 759 cancer patients received PN (6.6%). The majority of enrolled patients (97.2%) used commercially available PN and 71.2% of these used peripheral PN formulations. The average in-hospital PN duration was 16.1±19.9 days. Patients received only 65.4±25.4% calories of the recommended target calories. The in-hospital mortality of enrolled patients was 26.1%. Conclusion: We conclude that commercial PN is the most common form of PN administered to hospitalized adult cancer patients and the overall in-hospital mortality in the patients using PN is higher in South Korea compared to other countries.

Background : The purpose of this study was to describe the number and profiles of patients consulted by the nutrition support team (NST). Methods : We studied the claims data of the Health Insurance & Assessment Service (HIRA) in Korea August 2014 to December 2020. Results : Compared to 2015, the number of patients, count of NST consultation fee, and total amount of consultation fee increased 53.4%, 59.8%, and 75.0%, respectively, in 2020. However, the total number of patients and count of aseptic preparation fee of parenteral nutrition (PN) in 2020 compared to 2015 decreased by 17.3% and 11.7%, respectively. Both fees of NST consultation and aseptic preparation of PN were concentrated in the metropolitan area, and the aseptic preparation fees of PN were particularly focused on tertiary hospitals. NST consultation fees in patients age 65 or older accounted for 55.6% of all patients, while aseptic preparation fees of PN in patients age 5 or younger accounted for 47.9%. Though the count of aseptic preparation fees of PN continued to decrease, that of NST consultation fees are increasing. It suggests that clinical pharmacists have shifted from aseptic preparation-oriented work to consultation-oriented work. Conclusion : This study reported the economic aspects of NST consultation for the first time since its establishment in August 2014 in Korea. It indirectly suggests that the advisory activities of pharmacists, an essential human resource for nutrition therapy, are increasing.
