본 연구의 목적은 항암화학요법을 받는 고형암 환자를 대상으로 구강관리 개별교육과 냉동요법 및 벤지다민 구강함수를 포함한 구강관리 프로토콜 적용이 대상자의 구강상태와 수행에 미치는 효과를 파악하기 위함이다. 총 연구 대상자는 31명이었으며, 실험군에 13명, 대조군에 18명이 배정되었다. 실험군에게는 구강관리교육, 냉동요법 및 벤지다민 구강함수를 적용하였으며 대조군은 기존의 구강간호를 제공하였고, 대상자의 구강상태와 자가간호 수행정도를 측정하였다. 수집된 자료는 Mann-Whitney test, Friedman test, 및 Chi-square test로 분석하였다. 연구결과, 매 측정 시기 별 두 그룹 간 구강상태의 차이는 없는 것으로 나타났다. 그러나 두 그룹 모두 측정시기에 따른 구강상태의 변화는 유의하였는데 항암치료 후 14일경에 구강상태점수가 가장 낮게 측정되었다. 자가간호 수행정도는 실험군이 대조군보다 유의하게 높았으며 연구 완료 후 4개월까지 유지되는 것으로 나타났다. 이러한 결과는 종양간호사에 의한 환자개별교육의 효과로 여겨지며 고형암 환자의 구강상태 개선을 위하여 냉동요법과 벤지다민 구강함수에 대한 효과를 파악하기 위한 추가적인 연구가 요구된다.

Purpose: This study aimed to evaluate the effects of gargling with S-solution and gargling with A-solution on salivary pH, coated tongue, and dental plaque index in preschool children. Methods: Non-equivalent control group pretest-posttest design was used to select the participants. 99 preschool children were divided into three groups. Dependent variables were recorded at baseline, 30 minutes, and 7 days after the first treatment was given. The data were analyzed using $X^2$-test, ANOVA, and repeated measures of ANOVA. Results: There were no significant differences in dependent variables in pre-test. However, the salivary pH in the S-solution group had significantly increased after 30 minutes (p<.05) and then again 7 days (p<.01) after the first treatment. Also, the S-solution and A-solution groups had greater decrease in dental plaque index after 30 minutes and again 7 days after the first treatment (p<.001) than the control group. With respect to coated tongue, there were no significant differences among the three groups. Conclusion: The results of this study indicate that essential oil gargling after brushing is helpful in improving oral health due to auxiliary oral hygiene effects with natural products. Specifically, gargling with S-solution is more effective than A-solution on oral health in preschool children by neutralizing salivary pH and reducing dental plaque index.

Purpose: The purpose of this study was to examine the effects of cold oral gargling on oral discomfort among Non-Hodgkin's lymphoma patient undergoing chemotherapy. Method: An quasi-experimental, nonequivalent control group design was used. Thirty two patients receiving chemotherapy at G hospital in P city were recruited from August 1, 2002 to October 20, 2002. Sixteen were conveniently allocated into the experimental group and 16 into the control group. Participants in the experimental group used cold oral gargling while their counterparts used room temperature oral gargling. Subjective and objective oral discomforts were measured by the instruments developed by Beck. The SPSS WIN 10.0 program was used to analyze the data with t-test, ${\chi}^2$ -test, and repeated measures ANOVA. Findings: The participants in the experimental group reported less oral discomfort and showed better oral conditions than those in the control group at the post 7th, 14th, and 21st days. Participants in the experimental group reported better oral conditions in taste, tongue, eating, and saliva than those in the control group. Conclusion: The cold oral gargling seemed to be more beneficial than room-temperature oral gargling in reducing oral discomfort for the Non-Hodgkin's lymphoma patients undergoing chemotherapy.

Purpose: The purpose of this study was to compare the effects of gargling with A-Solution and 0.9% normal saline on xerostomia, halitosis, and salivary pH among nursing students. Methods: The study design was a randomized, controlled trial. The experimental group received oral gargling treatment for 15 seconds with A-solution while the control group received oral gargling treatment for the same time with 0.9% normal saline. Outcome variables were measured at baseline, 60 minutes, and 120 minutes. Results: The groups were homogeneous in general characteristics, and the outcome variables before the treatment between the experimental group and the control group. 1) There were no significant differences in xerostomia, halitosis, and salivary pH between the two groups. 2) There were no significant differences in xerostomia, halitosis, and salivary pH based on the time. 3) There were significant interactions between group and time in subjective halitosis (F=3.766, p=.034) only. Conclusion: These findings indicate that oral gargling with Aroma solution and 0.9% normal saline could have the same effect of reducing xerostomia and halitosis in nursing students.

Purpose: The purpose of this study was to examine the effects of oral gargling with an aromatic solution on xerostomia, objective oral status, and oral health-related quality of life in psychiatric inpatients. Methods: A nonequivalent control group with a non-synchronized design was used in this study. The experimental group (n=34) received oral gargling with an aroma solution, while the control group (n=33) gargled with 0.9% normal saline. Dependent variables were measured at pre-, post-, and follow-up test. Data were analyzed using an χ²-test, Fisher's exact probability test, t-tests, and repeated measures ANOVA using SPSS/WIN v.21.0. Results: After the intervention, significant differences were revealed in xerostomia (F=15.30, p<.001), objective oral status (F=38.44, p<.001), and oral health-related quality of life (F=62.70, p<.001) with an interaction effect between group and time. Conclusion: These findings indicate that gargling with an aroma solution is more effective than 0.9% normal saline for the oral health of psychiatric inpatients. Therefore gargling with an aroma can be safely recommended as a brief, economical, and positive intervention in clinical settings.

셀 수 있는 이산 자료(discrete count data)에 대한 분석은 여러 분야에서 활용되고 있지만 영(zero)을 과도하게 포함하고 있는 영과잉 자료는 자료의 성격상 포아송 분포를 따르지 못할 때가 있어 분석에 어려움이 따른다. Zero-Inflated Poisson(ZIP)모형은 이런 어려움을 극복하기 위하여 영에 대한 점확률을 가지는 분포와 포아송 분포를 합성하여 과도한 영과 영이 아닌 자료를 설명하는 모형이다. 설명 변수가 존재할 때는 포아송 분포 부분에서 반응변수의 평균과 공변량사이에 로그선형 연결함수를 사용한 Zero-Inflated Poisson Regression(ZIPR)모형이 사용될 수 있다. 본 논문에서는 Markov Chain Monte Carlo 기법을 이용한 ZIPR모형의 베이지안 추론방법을 제안하고, 이를 실제 구강위생 자료에 적용하며 다른 모형들과 비교한다. 그 결과 베이지안 추론 방법을 적용한 영과잉 모형의 추정오차가 다른 모형들의 추정오차보다 작았고, 예측치가 더 정확했다는 점에서 우수함을 알 수 있었다.
