  • 이 short note에서 우리는 bulk gadolinium의 강자성에서 상자성으로의 전이온도(즉, Curie점) 측정에 대한 결과를 보고하고자 한다. 이 결과보고는 gadolinium박막에 대한 이전의 결과에 정당성을 주기 위해서 쓰여졌다. 본 실험에서 bulk gadolinium의 Curie점은 시료의 저항을 온도의 함수로 측정함으로써 결정하였다. 이는 Curie점에서 비열의 특이성이 바로 비저항의 특이성으로 연결되기 때문이다. 결과적으로 우리는 bulk gadolinium의 Curie점이 19.2${\pm}$0.$3^{\circ}C$가 되고이 값은 비열의 실험치로 결정한 다른 그룹들의 실험값들과 잘 일치하고 있음을 알 수 있었다.

  • We propose coincidence and common fixed point results for a quadruple of self mappings satisfying common limit range property and weakly compatibility under generalized ${\Phi}$-contractive conditions i Non-Archimedean Menger PM-spaces. As examples we exhibit different types of situations where these conditions can be used. A common fixed point theorem for four finite families of self mappings is presented as an application of the proposed results. The existence and uniqueness of solutions for certain system of functional equations arising in dynamic programming are also presented as another application.

  • Aortic AIx(augmentation index) has been used to measure aortic stiffness and evaluate ventricular load quantitatively. Algorithm for the detection of augmentation point gradually increases the differential order to detect inflection point rather than detects the distinctive point that appears after a specific time. Developed algorithm for AIx is proved to provide more accurate results than the ones developed by previous studies with the deviation from $-11.5{\pm}14.34$ points to $-3.75{\pm}1.26$ points. Results could provide the basis for the measurement of aortic stiffness using easily-measurable radial artery pulse waves, and could be extended to develop a system for early diagnosis of various vascular diseases.

  • A descriptive correlation study was done to provide a basic data for comprehensive nursing care by analyzing the relationship between spiritual wellbeing, hope and perceived health status of the elderly. 195 respondents who lived at their homes and 148 respondents who lived at the facilities for elders such as nursing homes and elder's rehabilitation centers were selected and their age was over 60 years old. Paloutzian and Ellison(1982)'s spiritual wellbeing scale, Nowotny(1989)'s hope scale and Northern Illinois University's health self rating scale was used. From August 10th to August 25th, 1998, ready made questionnaires were handed out by researcher to those who can fill it out and for those who cannot fill out the questionnaires alone, the researcher read it and finished by interview. This study used Pearson's correlation coefficient for the hypothetic test and the average point and standard deviation of spiritual wellbeing, hope, and perceived health status were checked. To find out the difference between spiritual wellbeing, hope, and perceived health status by general characteristics ANOVA and Tukey test were used. The results are as follows : 1. The mean score for spiritual wellbeing of the elders was 42.27($SD{\pm}9.67$) in a possible range of 20-80. The average point of spiritual wellbeing was 2.11($SD{\pm}0.97$) point to 4 point full marks. The mean score of religious wellbeing was 21.37($SD{\pm}7.02$) and that of existential wellbeing was 20.90($SD{\pm}4.63$) in a possible range of 10 - 40. The average point of religious wellbeing was 2.14($SD{\pm}0.70$)points and existential wellbeing was 2.09($SD{\pm}0.46$) points to 4 point full marks. 2. The mean score for hope was 67.16($SD{\pm}12.28$) in a possible range of 29-116. The average point of hope was 2.31($SD{\pm}0.42$) points to 4 point full marks. 3. The mean score for perceived health status was 8.72($SD{\pm}2.49$) in a possible range of 4-14. 4. In testing the hypothesis concerning the relationship between spiritual wellbeing and hope, there was a statistically positive correlation(r=0.5209, p=0.0001). 5. In testing the hypothesis concerning the relationship between spiritual wellbeing and perceived health status, there was a statistically positive correlation(r=0.1427, p=0.0081). 6. In testing the hypothesis concerning the relationship between hope and perceived health status, there was a statistically positive correlation(r=0.2797, p=0.0001). 7. There were significant differences in spiritual wellbeing according to sex, religion, and present occupation. 8. There were significant differences in hope according to residential places, age, religion, educational level, family status, average monthly pocket money. 9. There were significant differences in perceived health status according to residential places, sex, age, educational level, present occupation and family status. From the above results it can be concluded that: There was a positive correlation between spiritual wellbeing and hope, spiritual wellbeing and perceived health status, hope and perceived health status.

  • A descriptive correlation study was done to provide a basic data for comprehensive nursing care by analyzing the relationship between spiritual wellbeing, hope and perceived health status of the rural elderly. 130 respondents who lived at their homes and nursing homes for elders in D county. Kyungbuk province were selected and their age was over 60 years old. Paloutzian and Ellison(1982)'s spiritual wellbeing scale. Nowotny(l989)'s hope scale and Northern Illinois University's health self rating scale was used. From September 2nd to September 30th, 2002, ready made questionnaires were handed out by researcher and two well trained nurse research assistants. to those who can fill it out and for those who cannot fill out the questionnaires alone, the researcher and assistants read it and finished by interview. This study used Pearson's correlation coefficient for the hypothetic test and the average point and standard deviation of spiritual wellbeing, hope, and perceived health status were checked. To find out the difference between spiritual wellbeing, hope, and perceived health status by general characteristics ANOVA and Tukey test were used. The results are as follows : 1. The mean score for spiritual wellbeing of the rural elders was $49.94(\pm5.62)$ in a possible range of 20-80. The mean score of religious wellbeing was $25.20(\pm3.91)$ and that of existential wellbeing was $24.74(\pm2.83)$ in a possible range of 10-40. The average point of religious wellbeing was $2.52(\pm0.39)$ points and existential wellbeing was $2.47(\pm0.28)$ points to 4 point full marks. 2. The mean score for hope was $67.68(\pm10.92)$ in a possible range of 29-116. The average point of hope was $2.33(\pm0.38)$ points to 4 point full marks. 3. The mean score for perceived health status was $9.95(\pm2.66)$ in a possible range of 4-14. The average point of perceived health status was $2.15(\pm0.72)$ point to 4 point full marks. 4. In testing the hypothesis concerning the relationship between spiritual wellbeing and hope, there was a statistically positive correlation(r=0.621. p=0.000). 5. In testing the hypothesis concerning the relationship between hope and perceived health status, there was a statistically positive correlation(r=0.305, p=0.000). 6. There were significant differences in spiritual wellbeing according to age(F=5.60, p=0.000), religion(F=11.61. p=0.000), family status(F=2.86, p=0.040) and average monthly pocket money(F=4.32, p=0.015). 7. There were significant differences in hope according to age(F=16.49, p=0.000), religion (F=3.56, p=0.009), educational level(F=8.94, p=0.000), present occupation(t=-3.13, p=0.002), family status(F=5.90, p=0.001) and average monthly pocket money(F=3.41. p=0.036). 8. There were significant differences in perceived health status according to present occupation(t=-2.16, p=0.033) average monthly pocket money(F=4.11, p=0.019). From the above results it can be concluded that: There was a positive correlation between spiritual wellbeing and hope, hope and perceived health status. There was no positive correlation between spiritual wellbeing and perceived health status. For futher study, adequate spiritual wellbeing scale and hope scale for rural elders should be developed and, age and religion factors has to be reconsidered. When the nurse implicate the nursing intervention which can be promote the spiritual wellbeing and hope, rural elder's spiritual wellbeing and hope can be improved and at the same time, their perceived health status also can be improved.

  • This study was conducted to patients visited oral maxillo-facial surgery, KNUH and the purpose of the study was to assess skeletal and dento-alveolar stability after surgical-orthodontic correction treated by skeletal Class III malocclusion patients with open bite versus non-open bite. This retrospective study was based on the examination of 40 patient, 19 males and 21 females, with a mean age 22.3 years. The patients were divided into two groups based on open bite and non-open bite skeletal Class III malocclusion patients. The cephalometric records of 40 skeletal Class III malocclusion patients (open bite: n = 18, non-open bite: n = 22) were examined at different time point, i.e. before surgery(T1), immediately after surgery(T2), one year after surgery(T3). Bilateral sagittal split ramus osteotomy was performed in 40 patients. Rigid internal fixation was standard method used in all patient. Through analysis and evaluation of the cephalometric records, we were able to achieve following results of post-surgical stability and relapse. 1. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in maxillary occlusal plane angle of pre-operative stage(p>0.05). 2. Mean vertical relapses of skeletal Class III malocclusion patients with open bite were $0.02{\pm}1.43mm$ at B point and $0.42{\pm}1.56mm$ at Pogonion point. In skeletal Class III malocclusion patients with non-open bite, $0.12{\pm}1.55mm$ at B point and $0.08{\pm}1.57mm$ at Pogonion point. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in vertical relapse(p>0.05). 3. Mean horizontal relapses of skeletal Class III malocclusion patients with open bite were $1.22{\pm}2.21mm$ at B point and $0.74{\pm}2.25mm$ at Pogonion point. In skeletal Class III malocclusion patients with non-open bite, $0.92{\pm}1.81mm$ at B point and $0.83{\pm}2.11mm$ at Pogonion point. There was no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in horizontal relapse(p>0.05). 4. There were no significant statistical differences between open bite and non-open bite with skeletal Class III malocclusion patients in post-surgical mandibular stability(p>0.05). and we believe this is due to minimized mandibular condylar positional change using mandibular condylar positioning system and also rigid fixation using miniplate 5. Although there was no significant relapse tendency observed at chin points, according to the Pearson correlation analysis, the mandibular relapse was influenced by the amount of vertical and horizontal movement of mandibular set-back(p=0.05, r>0.304).

  • PC 카메라를 이용하여 식초, 우유 및 탁주의 산도 적정을 자동화하였다. 피적정액의 화상에서 선택된 144개 pixel의 hue값의 평균값을 일정 시간 간격으로 산출하고, 이 평균값의 변화를 추적하여 적정액의 공급을 제어하는 방법을 사용하였다. 식초와 우유의 적정에서는 hue값 평균값이 적정전보다 5이상 증가하는 것을 종말점으로 하였으며, 탁주의 경우에는 70이상 증가하는 것을 종말점으로 하였다. 이 방법을 식초, 우유 및 탁주의 산도 적정에 적용한 결과, 식초의 경우에는 수동적정과 자동적정의 0.1 N NaOH용액의 소요량이 각각 $21.409{\pm}0.066mL$$21.403{\pm}0.055mL$였고, t-test 결과 p값이 0.841이었다. 우유의 경우에는 수동적정과 자동적정의 0.1 N NaOH용액의 소요량이 각각 $1.390{\pm}0.025mL$$1.388{\pm}0.027mL$였고, p값은 0.907이었다. 탁주의 경우에는 수동적정과 자동적정의 0.1 N NaOH용액의 소요량이 각각 $4.738{\pm}0.028mL$$4.752{\pm}0.037mL$였고, p값은 0.518이었다. 세가지 경우 모두 유의수준 0.05에서 유의차가 인정되지 않았으므로(p>0.05), 본 연구의 자동적정 방법을 산도 적정에 응용할 수 있다고 생각되었으며, 색변화를 이용하여 종말점을 검출하는 대부분의 적정에 무리 없이 적용할 수 있다고 생각되었다.
