  • 다중축척 공간데이터베이스란 동일한 현실 공간을 여러 축척의 데이터베이스로 저장한 것을 말한다. 이 다중축척의 데이터베이스는 기존에 구축된 원시 데이터베이스로부터 유도될 수 있다. 그런데 이 유도과정에서 원시 데이터베이스에 있던 기하 및 위상관계는 변형이 된다. 그리고 이 관계 변형은 유도된 데이터베이스의 무결성을 보장하지 못하는 원인이 된다. 때문에 유도된 데이터베이스가 원시 데이터베이스와 일관성이 있는지를 조사할 필요가 있다. 이 논문은 원시 데이터베이스와 유도된 다중축척 데이터베이스간의 위상적 일관성에 초점을 둔다. 특히, 2차원 공간객체가 1차원으로 축소되었을 때 위상관계의 일관성을 평가하는 방법을 제안할 것이다. 즉, 2차원 공간객체간에 위상관계를 표현하는 8가지 위상관계를 2차원과 1차원 공간객체간에 위상관계를 표현하는 19가지 위상관계로 일관성 있게 전환하는 4가지 방법을 제안할 것이다. 이 방법들은 새로 생성된 다중축척 데이터베이스의 위상관계가 원시 데이터베이스로부터 일관성 있게 유도되었는지를 판단하는 근거가 될 수 있다. 또, 다중축척 데이터베이스간에 위상관계의 일관성을 보장하므로 동일 공간에 주어진 사용자 질의는 축척에 상관없이 그 결과가 동일하게 된다.

  • Background: The Functional Assessment of Cancer Therapy - Breast (FACT-B) scale is widely used to measure health-related quality of life in cancer patients. The aim of the present study is to validate the FACT-B in a sample of Iranian women with breast cancer. Materials and Methods: The sample consisted of 300 women selected through non-random convenient sampling procedure from oncology hospitals and clinics in Kermanshah and Shiraz cities. They were asked to fill in the Persian versions of the FACT-B scale, Hospital Anxiety and Depression Scale, the European Organization for Research and Treatment of Cancer quality of life EORTC QLQ30. Confirmatory factorial analysis of the methods, concurrent validity and discriminant, and Cronbach's alpha for internal consistency were applied. Results: Internal consistency using Cronbach's alpha was 0.63 to 0.93 for the subscales and 0.92 for the total scale. Significant correlations between FACT-B and other measures indicate that this scale had concurrent and discriminant validity. The values of fit indices were satisfactory. Conclusions: The Persian version of the FACT-B scale is valid and reliable and, therefore, the scale can be used in research and clinical settings to assess health-related quality of life in Iranian patients with breast cancer.

  • Objectives: This study was conducted to develop the Mobility to Participation Assessment Scale for Stroke (MPASS) and assess its content validity, internal consistency, inter-rater and intra-rater reliability, and convergent validity in people with stroke living in the community. Methods: The MPASS was developed using published data on mobility-related activity and participation timing in elderly individuals, and then reviewed by community physical therapists. Content validity was established by reaching a consensus of experienced physical therapists in a focus group. The MPASS was scored for 32 participants with stroke (mean age 61.75±4.92 years) by 3 individual testers. Reliability was examined using the intraclass correlation coefficient (ICC), internal consistency using the Cronbach alpha coefficient (α), and convergent validity using the Pearson correlation coefficient (r) to compare the MPASS to the Modified Rivermead Mobility Index as a referent test of mobility. Results: The MPASS consists of 8 items, and its scoring system provides information on the ability of people with stroke to reach a movement level enabling them to live in society, including interactions with other people and safe living in the community. The interrater and intra-rater reliability were excellent (ICC, 0.948; 95% confidence interval [CI], 0.893 to 0.982 and ICC, 0.967; 95% CI, 0.933 to 0.989, respectively). Internal consistency was good (α=0.877). The convergent validity was moderate (r=0.646; p<0.001). Conclusions: The newly developed MPASS showed acceptable construct validity and high reliability. The MPASS is suitable for use in people with stroke, especially those who have been discharged and live in the community with the ability to initiate sitting.

  • Purpose: This study aimed to develop a self-assessment tool to evaluate program outcomes of nursing students in Korean nursing undergraduate education. Methods: The instrument development process consisted of literature review, focus group interviews, and item validation. A total of 117 items were analyzed through content validity testing. Data was gathered from 302 nursing students in Korea and analyzed using SPSS 21.0. Results: To construct validity, principal component analysis and Varimax rotation were used, and 12 factors, with a cumulative explanatory variance of 69.16%, were determined from 79 items. For internal consistency and reliability, Cronbach's ${\alpha}$ was .91. The half-split reliability results were .84 and .85, and the ROC curve showed an optimal cutpoint at 227. A five-point Likert scale was used for scoring. Conclusion: This instrument was found to have fair validity and reliability as a self-assessment tool for nursing student learning outcomes. Therefore, it can be used to evaluate program outcomes indirectly in nursing schools.

  • In Korean coastal areas, land reclamations are main development projects that should be based on environmental impact assessment(EIA), because those human interventions can change coastlines, damage tidal flats, and pollute adjacent areas to threat seafood safety and devaluate overall ecosystem service value. Existing procedures of the EIA for land reclamation projects were diagnosed and evaluated to enhance them. Problems were identified in the designation of survey areas, the consistency in survey sites and periods, the standardization of survey methods and reports, the confidence of survey results and the verification of predictions. Lack of integration was noticeable and could be improved by synthesizing different assessments from topography geography, marine physics, marine chemistry and marine biology. We suggest that successful precautionary marine environment management requires readjusting the cost of EIA, recruiting experts in marine environment, constructing database and establishing specialized assessment system.

  • 장애의 개념은 명확하게 정의하기는 매우 어려운 일로 알려져 있고, 전 세계적으로 실제 장애가 평가되는 방식은 추정되는 장애의 개념과는 괴리가 있다. 무엇이 적절한 장애평가인지 제시하기는 어려운데 이는 장애의 종류와 정도를 잘 반영해야 하고, 사회가 감당할 수 있는 평가자의 시간과 비용으로 일정 수준의 일관성, 신뢰도와 정당성이 담보되어야 하기 때문이다. 장애평가에서 매우 세세한 평가 규격을 사용하면 재량권이 제한되고, 이는 일관성과 신뢰도를 높이지만 개별적인 차이나 예외적인 상황을 무시하는 결과가 발생한다. 장애평가법 중에 손상접근 방법은 전 세계적으로 가장 오래되고 널리 사용되는 방법으로 현재 우리나라에서 사용되고 있는 대부분의 장애평가 방법이 여기에 속한다. 맥브라이드법은 비교적 많은 시간을 쓰지 않고 신체장애율과 노동능력 상실률을 함께 구할 수 있으며, 현재 법원에서 노동력 상실 평가에 사용하고 있는 중요한 방법이다. 여러 오류와 논란이 있음이 잘 알려져 있어 이의 수정이 요구되지만 현재로서 우리나라의 장애평가 방법에 대한 개선안은 또 다른 새로운 평가 기준을 제시하기 보다는 현재 가장 널리 사용되고 있는 맥브라이드 평가 방법을 보완하여 사용하는 것이다. 본 종설에서는 장애의 개념과 장애평가 방법에 대하여 설명하고, 장애평가 방법의 종류를 소개하면서 맥브라이드의 노동능력상실 평가법이 아직도 유용하게 사용될 수 있는 당위성에 대하여 알아보고자 한다.

  • Purpose: Oral mucositis (OM) is a serious consequence of chemotherapy that cancer patients must undergo. The objectives of this study were to find out reliability and validity of patients self-reported daily questionnaires on OM, and the impact OM makes on daily functions. Method: To test the reliability of oral mucositis daily questionnaire (OMDQ), internal consistency of the instrument (Cronbach's ${\alpha}$ and correlation between items) and test-retest reliability were analyzed. Criterion validity and discriminative validity were evaluated using WHO, oral assessment guide, and Nicolatou assessment tool. Forty-eight acute leukemic patients under chemotherapy were enrolled in this study. Result: The Cronbach's ${\alpha}$ coefficient indicated sufficient internal consistency. Correlations of Mouth and throat soreness (MTS) and MTSActivity Limitations (MTS-AL) were statistically significant. MTS and MTS-AL scores on consecutive days were highly correlated (days13,14=.84-.96; test-retest reliability). OMDQ scale had high criterion validity and discriminative validity. Patients with more severe WHO OM grades had higher MTS mean scores. Conclusion: Oral mucositis in acute leukemic patients under going chemotherapy can be easily quantified by patient self-administered OMDQ with reliability and validity.

  • Background: Pain with neuropathic characteristics is generally more severe and associated with a lower quality of life compared to nociceptive pain (NcP). Short form of the Douleur Neuropathique en 4 Questions (S-DN4) is one of the most used and reliable screening questionnaires and is reported to have good diagnostic properties. This study was aimed to cross-culturally validate the Hindi version of the S-DN4 in patients with various chronic pain conditions. Methods: The S-DN4 is already translated into the Hindi language by Mapi Research Trust. This study assessed the psychometric properties of the Hindi version of the S-DN4 including internal consistency and test-retest reliability after 3 days' post-baseline assessment. Diagnostic performance was also assessed. Results: One hundred sixty patients with chronic pain, 80 each in the neuropathic pain (NeP) present and NeP absent groups, were recruited. Patients with NeP present reported significantly higher S-DN4 scores in comparison to patients in the NeP absent group (mean (SD), 4.7 (1.7) vs. 1.8 (1.6), P < 0.01). The S-DN4 was found to have an AUC of 0.88 with adequate internal consistency (Cronbach's ${\alpha}=0.80$) and a test-retest reliability (ICC = 0.92) with an optimal cut-off value of 3 (Youden's index = 0.66, sensitivity and specificity of 88.7% and 77.5%). The diagnostic concordance rate between clinician diagnosis and the S-DN4 questionnaire was 83.1% (kappa = 0.66). Conclusions: Overall, the Hindi version of the S-DN4 has good internal consistency and test-retest reliability along with good diagnostic accuracy.
