Abstract: As known in clinical trial like DCCT, UKPDS, tight glycemic control is essential to prevent complications from diabetes mellitus(DM). In type 2 diabetes taking multiple medication, nonadherence to medications is common problem. The aim of our study is to investigate adher-ence rate of patients with type 2 DM and to evaluate association between many factors including adherence rate and HbA_(1C). 441 patients with type 2 DM who visited Busan National University Hospital endocrine internal department from Aug 13 to Sep 2, 2008(3weeks) were enrolled. We conducted a man-to-man questionnaire survey about general knowledge about diabetes mellitus, medicine and adherence, and measured HbA_(1C). Among them, 305 patients taking oral hypo-glycemic agent(OHA) were analyzed to investigate correlation between adherence rate and glycemic control. We studied 305 patients(male 126, female 179, average age 61.2±9.8 years, DM duration 8.6±6.4 years, average adherence 88.8±16.2%, average HbA_(1C) 7.03± 1.18%). HbA_(1C) showed significant relation with DM duration(r=0.137, p=0.017), number of aHA in regimen (r=0.135, p=0.018), dosage frequency(r=0.132, p=0.026), Medication Refill Adherence(MRA)(r=-0.124, p=0.030) and adherence(r=-0.168, p=0.003). Adherence had significant relation with MRA(r=0.148, p=0.010) but didn't have statical corelationship with DM duration, number of aHA and dosage frequency. Patients that their adherence rate exceed 90% took fewer OHA(p=0.011) and went on a better dietary treatment(p=0.007). In patients controlling diabetes mellitus with aHA, when adherence rate and MRA was higher, HbA_(1C) was lower. As a result, to improve adher-ence rate, it is necessary to enhance patient education, do careful consideration about prescrip-tion medicine number and dosage frequency

본 연구는 예비유아교사의 학업적 자기효능감과 그릿이 행복감에 어떠한 영향력을 미치는지 확인하는 데 목적이 있다. 이를 위해 부산광역시, 울산광역시, 경상남도 내에 소재하고 있는 대학교의 유아교육과에 재학 중인 예비유아교사 300명을 임의표집하여 연구대상으로 선정하였다. 예비유아교사의 학업적 자기효능감을 측정하기 위해 김아영, 박인영(2001)이 개발하고 타당화한 후 김병만, 김정주, 윤정진(2017)이 수정하여 사용한 학업적 자기효능감 검사도구를 사용하였다. 고, 그릿을 측정하기 위해 Duckworth, Peterson, Matthews와 Kelly(2007)가 개발한 Original Grit Scale(Grit-O)를 이수란(2014)이 한국실정에 맞게 번안한 척도를 사용하였으며, 행복감을 측정하기 위해 Seligman(2011)의 웰빙에 대한 PERMA 이론을 토대로 Butler와 Kern(2014)이 개발하여 김미진(2015)이 번안한 다차원적행복척도(Multidimensional Measure of Flourishing: MMF)를 사용하였다. 본 연구의 결과는 다음과 같다. 첫째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감에 대한 인식에 대한 결과로 모든 변인에서 보통 이상의 긍정적인 인식 정도가 나타났다. 둘째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감 간의 상관관계에는 유의미한 정적 상관관계가 있음을 알 수 있다. 셋째, 예비유아교사의 학업적 자기효능감은 예비유아교사의 행복감에 영향을 미치는 변인으로 나타났으나, 그릿은 예비유아교사의 행복감에 영향을 미치지 않는 변인으로 나타났다. The purpose of this study is to investigate the influence of pre-service early childhood teachers academic self-efficacy and grit on happiness. For this purpose, 300 Pre-service early childhood teachers in preschool education at universities located in Busan, Ulsan and Gyeongsangnam province were randomly sampled and selected. In order to measure the pre-service early childhood teachers academic self-efficacy, I used the academic self-efficacy test tool modified by Kim Byung-man, Kim Jung-ju and Youn Jung-jin (2017) after the development and validation of Kim Ae-Young and Park In-Young (2001). The original Grit Scale (Grit-O) developed by Duckworth, Peterson, Matthews and Kelly (2007) was used to measure grit. And to measure happiness, we used the multidimensional happiness scale developed by Butler and Kern (2014) and developed by Kim Mi-jin (2015) based on the PERMA theory of wellness in Seligman (2011). The results of this study are as follows. First, as a result of pre-service early childhood teachers perception of academic self-efficacy, grit, and happiness, positive perceptions were more than usual in all variables. Second, there is a significant positive correlation between the pre-service teacher s academic self-efficacy, grit, and happiness. Third, the academic self-efficacy of pre-service early childhood teachers was a factor affecting the happiness of pre-service early childhood teachers. Specifically, it was found that task difficulty preference, self-regulated efficacy, and self-confidence affect the happiness of pre-service early childhood teachers among the sub-variables of happiness. However, the sub-variables of Grit did not affect the pre-service teachers happiness.

This study was conducted to find a correlation between blood COHb and calculated COHb with expiratory air and related variables such as occupational and smoking factors. Author selected 69 healthy workers in 8 workplaces suspected CO exposure. Basic informations were collected by self-reported questionnaire and medical history taking. Author measured Indirect COHb concentration with expiratory air using Micro II-Smokerlyzer and blood COHb concentration using Oxymeter. The results of the study were summarized as follows : 1. In the smoker, mean blood COHb and calculated COHb with expiratory air were 2.21±0.98% and 2.27±0.97 %, and there was not a statistically significant difference. In the non-smoker, mean blood COHb and calculated COHb with expiratory air were 0.42±0.43 % and 0,65±0.30 %, and there was also not a statistically significant difference. 2. There were positive correlations between blood COHb and calculated COHb with expiratory air in both the smoker (r=0.91, p=0.0001) and non-smoker (r=0.73, p=0.0001). 3. In the smoker, the factors affected COHb were total smoking index (Pack × years) and passed time after the last smoking. 4. In the nonsmoker, the parking and driving groups had higher COHb concentration than others (p<0.05). In conclusion, there was no significant difference between indirect COHb concentration with expiratory air using Smokerlyzer and blood COHb concentration and there was a highly significant correlation between indirect and blood COHb concentrations. Therefore indirect COHb concentration with expiratory air is a useful screening method for CO exposure. Author suggest the resection of smoking during at least 90 minutes before measuring COHb concentration in order to exclude smoking effects.

Diffusion of Choline Chloride in Aqueous Solutions of Chondroitin Sulfate

Jung, Ok-Sun,Kim, Si-Joong,Kim, Hyoung-Man Korean Chemical Society 1984 Bulletin of the Korean Chemical Society Vol.5 No.6

Mutual diffusion coefficients of choline chloride were determined by using the diaphragm cell method in aqueous solutions of chondroitin sulfate A at $25^{\circ}C$. The diffusion coefficients of choline chloride in 0.1g/100ml, 0.5g/100ml and 1g/100ml respectively of chondroitin sulfate solutions were compared with those of binary systems of water-choline chloride. At low concentrations, the diffusion coefficients of the choline chloride in the presence of chondroitin sulfate were significantly smaller than the values obtained in the absence of chondroitin sulfate, indicating a strong interaction between these solutes. The effect of this interaction on the diffusion of choline ion is largest at higher chondroitin sulfate concentrations and at lower choline chloride concentrations. The influence of chondroitin sulfate is overcome at higher choline chloride concentrations. Self-diffusion coefficients of choline ion in the presence of chondroitin sulfate are also obtained. Excellent agreements were obtained between the experimental data and the calculated values obtained by using the Manning's equations. These observations suggest that the interaction between choline chloride and chondroitin sulfate involves primarily a long range electrostatic effect and there is no appreciable "condensation" or binding of choline ion to the chondroitin sulfate.

목적 : 자궁내막암 환자에서 시행된 복강경 수술의 임상적 결과를 평가하고 수술적 지표 및 재발률에 대하여 기존의 개복 수술과 비교하고자 하였다. 연구 방법 : 1997년 8월부터 2003년 11월까지 저자들은 임상적 병기 I기인 79명의 자궁내막암 환자에서 복강경하 자궁적출술과 골반 및 부대동맥 림프절 절제술을 시행하였다. 총 79명의 환자 중, 수술적 병기 I기와 II기로 판명된 74명의 환자를 연구 대상으로 하였다. 대조군으로는 같은 기간 동안에 개복수술을 시행한 환자중 복강경 수술군과 병기가 같은 168예를 선정하였다. 결과 : 평균 수술 기간, 수혈량은 양군에서 비슷하였으며, 평균 재원 기간은 복강경 수술군에서 유의하게 짧았다. 수술전후 및 만성 합병증의 발생은 개복 수술군에서 유의하게 증가되었으며, 획득한 림프절의 수는 복강경 수술군에서 유의하게 더 많았다. 복강경 수술군에서 1예, 개복 수술군에서는 2예에서 재발하였고, 2년 무병 생존률은 복강경 수술군과 개복 수술군에서 각각 97.5%와 98.6%으로 유의한 차이는 관찰되지 않았다. 결론 : 자궁내막암 치료로서 복강경 수술은 기존의 개복술을 대신할 수 있는 안전하고 효과적인 시술 방법이다. 개복 수술과 비교해 볼 때, 재발 및 생존율 면에서 차이가 없었지만, 향후 전향적이고 더 오랜 추적기간을 갖는 연구가 필요하다고 사료된다. Objective : To evaluate the outcomes of laparoscopic surgery and to compare surgical parameters and recurrence rate of these with those of conventional abdominal surgery in patients with endometrial cancer. Methods : From August 1997 to November 2003, we have performed 79 cases of LAVH (laparoscopically assisted vaginal hysterectomy) with or without lymph node dissection. Laparoscopic approach was adapted in patients with FIGO clinical stage I by imaging study. Of the 79 patients, 74 patients who were proved to be surgical stage I and II were enrolled in this comparative study. As a control group, We selected 168 cases for the laparotomy group of the same stages. Results : The mean duration of surgery, the amount of blood transfusion and hemoglobin chamges were similar in both the laparoscory and the convertional alparotomy group. The mean duration of hospital stay was significantly shorter in patients treated by laparoscopic surgery (10.2 vs. 15.5 days). The number of lymph node obtained was significantly higher in the laparoscopy group. Two year recurrence-free survival rates were 97.5% in laparoscopy group and 98.6% in laparotomy group (p=0.763). Conclusion : Laparoscopic surgery for the treatment of early stage endometrial cancer is safe and effective altematives in terms of perioperative complications. Overall and recurrence-free survival did not differ significantly in both groups however long term risk for recurrence and survival has yet to be defined.
