In this paper, we introduce a new measure called surprisal that estimates the informativeness of transactional instances and attributes in the item response dataset and improve the quality of association rules. In order to this, we set artificial dataset and eliminate noisy and uninformative data using the surprisal first, and then generate association rules between items. And we compare the association rules from the dataset after surprisal-based pruning with support-based pruning and original dataset unpruned. Experimental result that the surprisal-based pruning improves quality of association rules in question item response datasets significantly.

Objectives: The purpose of this study was to evaluate the quality of life in hemodialysis patients and compare it with those of depression or anxiety patients. Methods: Quality of life in hemodialysis patients(n=33) and depression or anxiety patients(n=34) was evaluated. we performed Korean Version of WHO Quality of Life Scale Abbreviated Version(WHOQOL-BREF), Beck Depression Inventory(BDI), State-Trait Anxiety inventory(STAI) to both hemodialysis patients and depression or anxiety patients. Results: The WHOQOL mean scores showed no differences between hemodialysis patients and depression or anxiety patients. Among WHOQOL domains, psychological domain score of WHOQOL was significantly higher in hemodialysis patients than in depression or anxiety patients. Anxiety score of hemodialysis patients was significantly lower than that of depression or anxiety patients, while depression score showed no difference. Conclusion: These results show that psychological domain score of WHOQOL was higher and anxiety score was lower in hemodialysis patients than in depression or anxiety patients. However, there were no significant differences in total QOL and depression between hemodialysis patients and depression or anxiety patients, and the prevalences of depression and anxiety were higher in hemodialysis patients than those of general population. This suggest that hemodialysis patients need more specialized help for psychiatric problems.

Purpose : The purpose of the present study was to analyze and evaluate prior studies published in Korea on the cancer-related quality of life, in order to make recommendations for further research. Materials and Methods : A total of 31 studies were selected from three different databases. The selected studies were analyzed according to 11 criteria, such as site of cancer, domain, independent variable, research design, self/proxy rating, single/battery instrument, translation/back translation, reliability, validity, scoring, and findings. Results : Of the 31 studies, approximately half of them were conducted using a mixed cancer group of patients. Many of the studies asserted that the concept of quality of life had a multidimensional attribute. Approximately 30% were longitudinal design studies giving information about the changes in quality of life. In all studies, except one, patients directly rated their level of quality of life. With respect to the questionnaires used for measuring the quality of life, most studies did not consider whether or not their reliability and validity had been established. In addition, when using questionnaires developed in other languages, no studies employed a translation/ back-translation technique. All studies used sum or total scoring methods when calculating the level of quality of life. The types of variables tested for their influence on qualify of life were quite limited. Conclusion : It is recommended that longitudinal design studies be peformed, using methods of data collection whose validity and reliability has been confirmed, and that studies be conducted to identify new variables having an influence on the quality of life.

이 연구는 환자의 치위생학적 지식 및 실천 정도가 구강건강과 관련된 삶의 질에 미치는 영향을 측정하고자 평가도구중 하나인 구강건강 영향지수(OHIP)를 사용하여 평가하였다. 그 결과 예방적인 지식이나 일상에서 매일 사용하는 구강용품지식 및 사용방법 지식이 높아야 주관적으로 느끼는 삶의 질이 높게 나타났다. 그리고 진료 형태별 지식과 같이 경험으로 습득한 지식은 높을수록 주관적으로 느끼는 삶의질이 낮게 나타났다. 반면 심미치료중의 하나인 미백치료지식은 높을수록 주관적으로 느끼는 삶의 질이 높게 나타났다. 즉 예방적이고 심미적인 지식이 구강건강영향지수에 영향을 미치는 것으로 분석된다.

This study was conducted to evaluate the quality of meta-analysis of social work in South Korea using the Assessment of Multiple Systematic Review (AMSTAR). Electronic databases including the Korean Studies Information Service System (KISS), DBpia, and RISS4U were searched for 'meta-analysis', 'social work', and 'social welfare' from 2000 to December 2015, and 42 meta-analysis studies were included. Data were analyzed using descriptive statistics, t-tests, and ANOVA. The mean score for AMSTAR evaluation was $4.766{\pm}1.66$, while 19 studies (45.2%) were classified at the low-quality level, and 22 (52.4%) were at the moderate-quality level. The scores of quality assessment were analyzed by publication year, participants, number of studies included, number of DB, reporting study quality, extraction diagram and topics. The findings indicated that the following changes should be implemented to improve the quality and reliability of meta-analysis results in social work research: 1) common reporting guidelines should be provided for the social work field, 2) quality analyses of each study should be conducted to achieve a high level of evidence of effectiveness of social work interventions, 3) the characteristics of the included studies should be provided, and 4) a consensus and procedure based on at least two independent data extractors should be reported.

This study aimed to find the problems of evidence-based complementary and alternative medicine and seek the future development direction by evaluating the quality of oriental medicine related systematic review(SR) studies using AMSTAR tool. The 26 SR studies related to oriental medicine were searched from the database of DBPIA, OASIS, and KISS, and they were evaluated on the basis of AMSTAR. The average of AMSTAR for the quality assessment of SR studies was 6.0 point, and the 26 studies included 2 high quality studies (7.7 %), 21 normal quality studies (80.8 %), and 3 low quality studies (11.5 %). The quality of studies was not correlated with the publication years. The quality of oriental medicine related SR studies need to be improved steadily. Furthermore, continued efforts to promote the evidence-based practice in the field of Oriental Medicine will help to establish foundation for the convergence approach in the healthcare sector.

Purpose: The patient's perspective in the assessment of quality of care has become increasingly important. The purpose of this paper was to introduce the concept of 'QUality Of care Through patient's Eyes (QUOTE)', to analyze the papers using QUOTE through an integrative review method, and to present the attributes of the QUOTE evaluation. Methods: Data were collected from electronic databases. Inclusion criteria were publication in English from 1997 to 2013, as a peer-reviewed research article, with an empirical study focused on QUOTE. Thirty two papers met the criteria and were analyzed. Results: QUOTE had been applied to various groups of patients such as those with various diseases since 1997 in the Netherlands. Four themes were retrieved from synthetic analysis of the thirty-two papers using QUOTE; 1) acceptance of individuation of the patient and family, 2) evaluation of diverse nurses' competencies, 3) evaluation of quality of nursing environments, and 4) participation of patient in the whole process of evaluation. Conclusion: The strengths of QUOTE are that it attempts to overcome the conceptual and methodological problems associated with evaluation of quality of care. Our results imply that QUOTE evaluation could be an effective strategy to improve care of patients in clinical setting.
