The value of blood sugar is measured by a personal blood glucose meter which consists of two parts: a glucose strip and a blood glucose meter. A personal blood glucose meter makes use of electric media which are composed of glucose oxidase and electron. This study is to propose a method of reliability demonstration test derived from field data analysis and FMEA(Failure Mode and Effect Analysis). Detailed Conditions for reliability demonstration test are selected from the comparison of various failure mechanisms. The most dominant failure mechanism is wear-out which is caused by strip insertion/extraction. The testing device that can reproduce the failure mechanism of strip insertion/extraction is made to conduct reliability demonstration test. Using the testing device, it is confirmed that target lifetime of selected devices is more than 2 years.

A blood-glucose meter is one of the in vitro diagnostic devices to measure and control the glucose concentration of diabetics. In order to measure the glucose level in the blood, the common method is to measure the amount of electrons, that is, the output current generated by glucose oxidation after a blood sample is inserted into the test strip containing an enzyme. The hematocrit is an obstacle in measuring accurate blood glucose concentration. This paper deals with the design and implementation of a blood-glucose meter to correct the hematocrit interference. We propose a sequential method which measures impedance using the alternating current and then measures glucose in the blood using the direct current. In addition, this paper introduces how to use commercial glucose strips based on the proposed system. Finally, we conducted the performance evaluation of the proposed system by comparing the measured current and impedance with those of the references. As a result, the standard deviation of the current measurement is approximately 0.6nA and the impedance measurement error for measuring the hematocrit is approximately within 1%. The proposed system will improve the accuracy of the conventional blood-glucose meter by reducing the hematocrit interference.

Background : The purpose of this study was to examine that the effects of Peony-Licorice (PL) mixture supplementation on post-exercise blood glucose and lactate in professional women basketball players. Methods: Eleven professional women basketball players were participated in this study. The subjects participated in two trials, PL supplementation and water supplementation. They did 20-meter shuttle run test, and measured blood glucose and lactate level before, immediately, after 3 minutes, after 5 minutes and after 10 minutes the test. Results: There was not interaction effect on blood glucose(p<0.433) and lactate(p<0.770) levels. Blood glucose and lactate levels were increased in PL group and water group after the test. Conclusion: PL supplementation could not affect changing blood glucose and lactate level. Therefore, we suggest that PL supplementation may not be positive ergogenic aid for improving exercise performance in professional women basketball players.

본 연구는 소방공무원 수험생을 대상으로 12주간 훈련이 체력요인, 심혈관계요인 변화에 미치는 효과를 규명하고자 하였다. 이를 위해 자발적 참여를 동의한 20-30대 남자 40명을 소방공무원 체력검사종목 훈련군(이하 PT group), 소방공무원 체력검사종목과 유산소훈련 병행군(이하 PT+AR group), 소방공무원 체력검사종목과 무산소훈련 병행군(이하 PT+AN group), 소방공무원 체력검사종목과 유무산소복합훈련 병행군(PT+CO group)으로 나누어 실시하였다. 분석항목으로는 체력요인(악력, 배근력, 앉아 윗몸 앞으로 굽히기, 제자리멀리뛰기, 윗몸일으키기, 20m왕복오래달리기), 심혈관계요인(총콜레스테롤, 중성지방, 고밀도지단백 콜레스테롤, 저밀도지단백 콜레스테롤, 글루코스, 허리둘레, 수축기혈압, 이완기혈압) 및 Framingham Heart Risk Score와 체력요인, 심혈관계 요인의 관계를 비교 분석하였으며 다음과 같은 결론을 얻었다. 본 연구에서 실시한 12주간 체력검정을 위한 훈련이 체력과 심혈관계에 효과적임을 확인 할 수 있었다. 따라서, 체력검정을 위한 훈련이 소방공무원 수험생들의 체력향상과 심혈관질환 위험을 감소시키는데 효과가 있는 것으로 판단된다.
