  • Objectives: The purpose of this study was to test the reliability and validity of an assessment tool for dental hygienists' consideration of patients with mild disabilities. Methods: Thirty-seven preliminary questions were compiled through literature review, and thirty-two questions were selected through content validity testing by eight experts. Two hundred and three dental hygienists completed the assessment tool as an online survey. The construct validity, internal consistency, and test-retest reliability of the tool were investigated using the SPSS 26.0 program. The construct validity was assessed using exploratory factor analysis. The internal consistency was assessed using Cronbach's alpha. The intraclass correlation coefficient (ICC) value with 95% confidence intervals was calculated for test-retest reliability. Results: Ten items and four factors were selected through exploratory factor analysis. The internal consistency reliability of the tool was found to be Cronbach's alpha=0.658, and test-retest reliability was found to be ICC=0.812. Conclusions: An assessment tool of care for patients with mild disabilities by dental hygienists is a reliable and valid tool suitable for the job characteristics of dental hygienists. It can be used in clinical practice and research.

  • Objective : Our objective is to analyze the occurrence, clinical course and risk factors for glioma patients with leptomeningeal metastasis (LM) according to different metastasis patterns and clinical variables. Methods : We retrospectively reviewed data from 376 World Health Organization (WHO) grade II-IV adult glioma patients who were treated in the National Cancer Center from 2001 to 2020. Patients who underwent surgery at other institutions, those without initial images or those with pathologically unconfirmed cases were excluded. LM was diagnosed based on magnetic resonance imaging (MRI) findings or cerebrospinal fluid (CSF) cytology. The metastasis pattern was categorized as nodular or linear according to the enhancement pattern. Tumor proximity to the CSF space was classified as involved or separated, whereas location of the tumor was dichotomized as midline, for tumors residing in the thalamus, basal ganglia and brainstem, or lateral, for tumors residing in the cerebral and cerebellar hemispheres. Results : A total of 138 patients were enrolled in the study. A total of 44 patients (38%) were diagnosed with LM during a median follow-up of 9 months (range, 0-60). Among the clinical variables, tumor proximity to CSF space, the location of the tumor and the WHO grade were significant factors for LM development in univariate analysis. In multivariate analysis, the midline location of the tumor and WHO grade IV gliomas were the most significant factor for LM development. The hazard ratio was 2.624 for midline located gliomas (95% confidence interval [CI], 1.384-4.974; p=0.003) and 3.008 for WHO grade IV gliomas (95% CI, 1.379-6.561; p=0.006). Conclusion : Midline location and histological grading are an important factor for LM in glioma patients. The proximity to the CSF circulation pathway is also an important factor for WHO grade IV glioma LM. Patients carrying high risks should be followed up more thoroughly.

  • Background/Aims: The etiology of superficial non-ampullary duodenal epithelial tumors (SNADETs) remains unclear. Recent studies have reported conflicting associations between duodenal tumor development and Helicobacter pylori infection or endoscopic gastric mucosal atrophy. As such, the present study aimed to clarify the relationship between SNADETs and H. pylori infection and/or endoscopic gastric mucosal atrophy. Methods: This retrospective case-control study reviewed data from 177 consecutive patients with SNADETs who underwent endoscopic or surgical resection at seven institutions in Japan over a three-year period. The prevalence of endoscopic gastric mucosal atrophy and the status of H. pylori infection were compared in 531 sex- and age-matched controls selected from screening endoscopies at two of the seven participating institutions. Results: For H. pylori infection, 85 of 177 (48.0%) patients exhibited SNADETs and 112 of 531 (21.1%) control patients were non-infected (p<0.001). Non-atrophic mucosa (C0 to C1) was observed in 96 of 177 (54.2%) patients with SNADETs and 112 of 531 (21.1%) control patients (p<0.001). Conditional logistic regression analysis revealed that non-atrophic gastric mucosa was an independent risk factor for SNADETs (odds ratio, 5.10; 95% confidence interval, 2.44-8.40; p<0.001). Conclusions: Non-atrophic gastric mucosa, regardless of H. pylori infection status, was a factor independently associated with SNADETs.

  • 부도예측을 위한 지식기반시스템에서 모델은 실적에 영향을 끼치는 주요한 요인이다. 예측 모형의 개발에 있어 초기 연구들은 통계기법 및 인공지능기법들을 이용하여 최고 실적을 가지는 단일 모델을 만드는데 주력하였다. 1980년대 중반 이후에는 다수 기술의 통합(하이브리드), 더 나아가, 다수 모델의 결과의 결합(앙상블) 기법이 수많은 실험에서 개별 모델들보다 더 나은 결과를 보여왔다. 다수 모델들의 출력값들을 결합하여 한 개의 최종 예측값을 산출하는 앙상블 모델링에서 결합기법은 앙상블의 예측 정확도에 영향을 끼치는 중요한 이슈이다. 본 논문은 부도예측을 위한 앙상블 결합기법으로서 앙상블 멤버들이 다른 유형의 연속형 수치 출력값들을 산출하더라도 통일된 확신을 측정할 수 있는 확신 기반의 선택 접근법을 제안하고 이에 대한 앙상블 멤버 사이즈의 영향을 연구하였다. 실험 결과는 앙상블 멤버들의 생성 타입에 따라 결합하는 모델 개수를 변화시켰을 때 가장 많은 기본 모델들을 가지는 앙상블에서의 제안 결합기법이 부도예측에 가장 자주 사용되는 다른 방법들에 비해서도 가장 높은 실적을 가진다는 것을 보였다.

  • As a family respond to any stressful situation as a whole system, cancer diagnosis of a child, as a serious life event, could be emotional shock to destroy homeostasis of the family system. A family has a resilient capacity to adjust and adapt to stressful events. Previous studies have been focused on family stress and adaptation, but little attention has been given to family value as one of resilient factors. The data for model testing were collected from July 18, 2000 to August 30, 2000 and the analysis included 309 parents of children who are diagnosed as cancer, 18 or less years of age, and treated either hospitalized or at the outpatient clinics. The data analysis utilized SAS 6.12 and LISREL 8 for descriptive statistics, correlation, cluster analysis, factor analysis, and LISREL. The study findings are as follows. 1) Monthly income (γ=-0.28, t=-5.81) was the most important factor to explain family strain along with family support (γ=-0.11, t=-2.43), severity of children's illness (γ=0.26, t=5.22), and family stressor (γ=0.22, t=4.62). All of these factors together explained 40% of variance in family strain. 2) Among general family value, the relationship with the parents (γ=0.28, t=4.89) and relationship with the children (γ=0.20, t=3.60) showed positive effects to family value for cancer children, while relationship with the spouse (γ=-0.19, t=-3.22) and the age of the cancer children (γ=-0.11, t=-2.21) showed negative effects. These predictors together explained 22% of variance in family value for cancer children. 3) Family hardiness was explained mostly by family strain (γ=-0.53, t=-8.65) along with direct negative effects of family persistency and indirect negative effects of severity of children's illness, family stressor, relationship with the spouse, and the children's age. Family value for cancer children was the most important predictor with positive effect (γ=0.44, t=6.76) along with indirect effects of monthly income, relationship with the parents, relationship with the children, support from family and significant others, and confidence with the health professionals. 51% of variance in family hardiness was explained by all of these predictors. 4) The most important predictor for family adaptation was family stressor (γ=-0.50, t=-6.85) with direct and indirect negative effects along with the severity of children's illness (γ=-0.27, t=-5.21). However, family value for cancer children showed compromised total effect (γ=-0.13, t=-1.99) with negative direct effects (γ=-0.28, t=-3.43) and positive indirect effects (γ=0.14, t=3.01). Similarly, confidence with the health professionals also showed compromised total effect (γ=0.09, t=1.99) with positive direct effects and negative indirect effects. Family hardiness showed the biggest positive direct effects while other factors such as monthly income, family stressor, family persistence, support of family and significant others, relationship with the parents, relationship with the children, and relationship with the spouse, and children's age showed indirect effects only. 39% of variance in family adaptation was explained by all of these predictors.

  • Antenatal care is zoomed toward3 assisting the Individual to achieve safe and wholesome state of health during pregnancy. Nature of fear is assumed to be rooted to complex interaction between past experiences, human relationship and present state of health, however. specific relationship between fear and the variables have not yet been ascertained. This study is designed to investigate the nature of fear of pregnancy, and the correlation between fear and the personal and environmental variables such as personal characteristics past experiences. and psycho-social factors. During the period from October 23 to November 5, 215 pregnant and 104 non-pregnant women of similar chronological are group residing in Seoul were interviewed according to check-list by random General anxiety test, general personality test and test for fear of pregnancy, family according to specific variables such as past experiences of Pregnancy and childbirth, structure of family, family relationship and month of pregnancy was done to the group of pregnant women. To non-pregnant group, general anxiety test was performed to compare with pregnant group. Results of the study are as follows; 1. Hypothesis 1; Degree of general anxiety will be higher e pregnant women compared to that of non-pregnant women. There is no significant difference between the general anxiety of pregnant women and that of non-pregnant women. Therefore, hypothesis I is rejected. 2. Hypothesis 2: Fear of pregnancy and general anxiety will be correlated with personality factors. Through test for fear of pregnancy and general anxiety, a meager contra-correlation between fear and only two personal factors (R and E factor) is revealed but there is no significant correlation between fear and other personal factors (A.S. and T factor). Degree of fear of pregnancy tends to b: higher in the group with low personality factors; responsibility and emotional stability expect the correlation between ascendancy, sociability, and confidence-inferiority. non-significant. Through general anxiety test, level of general anxiety tends to be higher in the group. with low personality factors; responsibility. emotional stability, and confidence except ascendency and sociability, non-significant. Hypothesis 2 is partially supported. 3. Hypothesis 3; General anxiety and fear of pregnancy will be correlated with the past experience-ol pregnancy, and child-birth experience. Though general anxiety test and test for fear of pregnancy, non-significant difference is revealed by P〉.05 level Hypothesis 3 is rejected. 4. Hypothesis 4: General anxiety and fear of pregnancy will be correlated with the month at pregnancy will be correlated with the month of pregnancy. Through tests of general anxiety and fear, significant correlation is revealed degree of fear by-P〈.05 level (CR=1.98) and level of general anxiety by P〈.005 level (CR=3. 11) is higher in the earlier stage of pregnancy. Hypothesis 4 is supported. 5. Hypothesis 5, 6, 7; General anxiety and fear of pregnancy will be correlated with socio-economic status, family structure, and family relationship. Through general anxiety test and tear of pregnancy test, non-significant is revealed by P〉.05 level. Hypothesis 3.6.7 are rejected. Conclusion and recommendation Level of general: anxiety and degree of fear of pregnancy is shown not to be correlated with variables of past experiencers of pregnancy and child-birth. and family factors except the month of - pregnancy. Personal characteristics are shown to be partially contra-correlated meagerly with genera anxiety and fear of pregnancy. This study revealed contrasted results, in regard to presence of correlation between general anxiety and fear of pregnancy to other thesis. In this context. further studies under controlled environment is recommended.
