본 연구는 재개발 이후 원주민들의 재정착 비용 및 재정착 결정요인을 분석하고자 하는 것이다. 재정착비용의 범위는 실 데이터를 활용하여 재개발 후 해당지역의 기존아파트 시세의 평균증가율이 204%를 나타남을 보였다. 이에 근거하여 재정착비용을 원주민 종전자산가격의 150% 이하, 180% 이하, 200% 이하 그리고 200% 초과의 4개의 구간으로 설정하여 설문을 실시하였다. 분석대상 지역으로 부산시 재정비촉진지구로 지정된 4개의 지역인 서금사재정비촉진지구, 시민공원재정비촉진지구, 충무재정비촉진지구 그리도 영도재정비촉진지구 지역을 대상으로 설문조사를 실시하였다. 독립변수는 크게 가구주특성, 주거생활특성, 주택특성 그리고 재정비에 관한 원주민의 견해로 구성하였다. 분석방법으로는 순서화된 재정착의 비용범위 중 하나의 구간을 선택한 응답자와 그 외의 구간을 선택한 응답자간의 특성을 파악할 수 있는 순서형로짓모형(Ordinal Logit Model)을 이용하여 분석하였다. 분석결과는 다음과 같다. 원주민이 생각하는 재정착비용의 범위는 원주민 종전자산가격의 1.5배정도 상승한 가격이 적당한 것으로 나타났으며, 유의한 변수로는 가구주 특성에서 성별, 직업, 소득 주거생활특성에서는 주거지역만족도, 지역애착도 주택특성으로는 주택형태, 주택규모, 소유형태 마지막으로 재정비에 관한 원주민의 견해에서는 완료기간으로 나타났다.

Using the concept of codes on ordered sets introduced by Brualdi, Graves and Lawrence, we consider perfect codes on the ordinal sum of two ordered sets, the standard ordered sets and the disjoint sum of two chains.

In this paper, we generalize a few results of [7, 10] for lower radical classes of rings, by using the limit ordinal construction for lower radical classes of hemirings.

In this paper we introduce the notions of expansive homeomorphism and its properties, and study the relation between countable compacta and ordinal numbers. Our results extend and improve those of T.Kimura and others.

두 평정자가 R개의 순서형 반응 범주로 각 개체를 분류한 $R{\times}R$ 분할표에 대해, 불합치의 정도를 가중치로 부여한 가중 합치도 $H_{\omega}$를 제안하고, 최대 우도추정량 및 분산을 유도하였다. 또한 $2{\times}2$ 분할표에서 Feinstein과 Cicchetti(1990)가 제기한 마지막 역설을 새롭게 정의하고 증명하였으며, ${\kappa}$의 새로운 역설을 제기하고, ${\kappa}$와 주변분포의 전반적인 관계를 정리하였다.

Background: The purpose of this study was to examine the impact of the regional characteristics on the accessibility of emergency care and the impact of emergency medical accessibility on the patients' prognosis and the emergency medical expenditure. Methods: This study used the 13th beta version 1.6 annual data of Korea Health Panel and the statistics from the Korean Statistical Information Service. The sample included 8,119 patients who visited the emergency centers between year 2013 and 2017. The arrival time, which indicated medical access, was used as dependent variable for multi-level analysis. For ordinal logistic regression and multiple regression, the arrival time was used as independent variable while patients' prognosis and emergency medical expenditure were used as dependent variables. Results: The results for the multi-level analysis in both the individual and regional variables showed that as the number of emergency medical institutions per 100 km² area increased, the time required to reach emergency centers significantly decreased. Ordinal logistic regression and multiple regression results showed that as the arrival time increased, the patients' prognosis significantly worsened and the emergency medical expenses significantly increased. Conclusion: In conclusion, the access to emergency care was affected by regional characteristics and affected patient outcomes and emergency medical expenditure.

Pain is subjective, while statistics related to pain research are objective. This review was written to help researchers involved in pain research make statistical decisions. The main issues are related with the level of scales that are often used in pain research, the choice of statistical methods between parametric or nonparametric statistics, and problems which arise from repeated measurements. In the field of pain research, parametric statistics used to be applied in an erroneous way. This is closely related with the scales of data and repeated measurements. The level of scales includes nominal, ordinal, interval, and ratio scales. The level of scales affects the choice of statistics between parametric or non-parametric methods. In the field of pain research, the most frequently used pain assessment scale is the ordinal scale, which would include the visual analogue scale (VAS). There used to be another view, however, which considered the VAS to be an interval or ratio scale, so that the usage of parametric statistics would be accepted practically in some cases. Repeated measurements of the same subjects always complicates statistics. It means that measurements inevitably have correlations between each other, and would preclude the application of one-way ANOVA in which independence between the measurements is necessary. Repeated measures of ANOVA (RMANOVA), however, would permit the comparison between the correlated measurements as long as the condition of sphericity assumption is satisfied. Conclusively, parametric statistical methods should be used only when the assumptions of parametric statistics, such as normality and sphericity, are established.

The purpose of this study was on effect of Bopejungcheuntang(BPJC) for atopic dermatitis. During 5 months between January and May 2000, BPJC water extract administered to patient suffering from atopic dermatitis, in Dep. of Pediatrics, Dongguk university Pundang Oriental Hospital and this study was conducted for 27 patient (male 17, female 10) The result were as follows 1. The distribution of remedial values were improvement (51.9%), unresponsiveness(37.0%), depravation(11.1%). 2. After dispensing BPJC, ordinal sites of atopic dermatitis were inner space of elbow and knee joint, face and neck, back and abdomen, wrist and ankle. Befor and after dispensing BPJC this ordinal sites were similar but after dispensing BPJC, the other sites except head is improved. Order of symptomatic improvement is itching, licheniasis, erythema, exudate. Both itching and exudate is significantly improved. 3. According to way of water extract, symptomatic improvement is most excellent with general water extract & distiled water, the second is general water extract, the third is distiled water. 4. BPJC effect on atopic dermatitis is not significantly affected by sex, day of falling ill, medical treatment, resident environment, feeding, character and duration of medical treatment.

Purpose: This study was done to examine the incidence of oral mucositis in hematopoietic stem cell transplantation patients and to identify factors influencing oral mucositis and patient outcomes according to severity. Methods: In this retrospective study, data were collected from electronic medical records of 222 patients who had received hematopoietic stem cell transplantation. Oral mucositis was evaluated using WHO's assessment scale. Data were analyzed using Chi-square test, Fisher exact test, Spearman's correlation, Ordinal logistic regression, ANOVA and Kruskal-Wallis test. Results: A total of 69.8% of the patients evaluated developed oral mucositis (grade II and over). As a results of ordinal regression, factors influencing oral mucositis severity were found to be diagnosis, type of transplantation, oxygen inhalation and the number of antiemetics administration before transplantation. The severity of oral mucositis was found to increase the days of hospitalization, days of TPN administration, days of using antibiotics and the number and dosage of analgesics. Conclusion: The results would help predict severity of oral mucositis in hematopoietic stem cell transplantation patients and suggest that provision of appropriate nursing assessment and oral care would improve patient outcomes.
