Although the demand for the use of public data increases in accordance with the expansion of Government 3.0, the poor level of data quality and its management currently implemented is becoming obstacles to opening data to the public. To improve the efficiency of management, linkage and usage for data, standardized processes for data quality management have to be prepared and appropriate data quality assessment criteria should be established. In this paper, we propose the organizational maturity model that can assess the public data quality management level. This model consists of the process reference model and the measurement framework. Fifteen processes grouped by the PDCA cycle are defined in the process reference model. The measurement framework measures the organizational maturity level based on process capability levels. The organizational maturity model can be used to establish objectives and directions for public data quality improvement by diagnosis of current level of public data quality management and problem solving. This model can also facilitate open to the private sector and activate usage of stable public data through reliability enhancement.

The ratio of the deterioration housing in rural area was 29.6%, but it was 18.3% in urban area based on a 2018 survey. In consideration of the point, this study aims to analyze the actual condition of indoor air quality in rural houses to provide basic data for improving the indoor air environment. It was investigated 15housings of Hongseong-gun, Chungchengnam-do. To investigate the correlation between indoor air quality and housing type, both the field survey of housing type and precision diagnosis of concentration of indoor air pollutants such as HCHO, TVOC, Fine dust(PM-10, PM-2.5), CO₂, Radon. The results of this study are as follows. First, according to the average value of each element of rural old housing, the construction year was distributed in 1939~2004, and 12households(80%) living in houses older than 30years have passed for about 46years. As for the housing area, more than 12houses(80%) of 60㎡ or more and 3 houses (20%) of less than 60㎡ were often living in relatively small-scale housing. Second, as a result of measuring indoor air pollutants in rural houses, substances exceeding the standard values were found in HCHO, TVOC, CO₂. Third, in the case of Fine dust and Radon, none of such factors were exceeded the standard. Fourth, there was no significant difference in indoor air quality depending on housing type in rural houses. This paper is expected to contribute to the regional development projects and effective implementation of rural policies.

In many cases, modern aircraft are equipped with data acquisition system which checks the structural integrity of the aircraft. The analysis of the vibration data collected with the system is generally performed in dependence on a skilled expert who is familiar with aircraft design. Therefore, it is difficult to provide a representative and objective defect identification standard for general users. In this paper, we shows that it is possible to identify the type of maneuvers and faults by using the Principal Component Analysis(PCA) method in the vast vibration data collected during aircraft operation without using the existing aircraft design analysis. We classified the ROK Army aircraft vibration data for maneuvers and faults types, and applied the PCA to the classified data. Our result shows that it is possible to develop an objective maneuver/fault identification method without design analysis for general users.

Background: This research was planned with the aim of determining the effect of symptom frequency of children with cancer on the quality of life of their parents. Materials and Methods: In gathering the research data, the Child and Parent Information Form, the Symptom Evaluation Form and the Family Version of Life Quality Scale in Cancer Patients were used. Evaluation was made by using percentage calculations, Kruskal Wallis test, Bonferroni adjusted t-test and Bonferroni adjusted Mann-Whitney U test. The significance level was accepted as 0.005. Results: Some 37.6% of the participant children were female and 62.4% were male, with an average age of $10.2{\pm}4.5$. While 41.0% were newly diagnosed, 46.2% were in remission and 12.8% was in relapse. Highly significant differences were detected according to the symptom frequency with parent physical and psychological health, social anxiety, and spiritual wellness sub-dimensions, as well as total point averages. Conclusions: It is thought that following up the symptoms that might develop depending on cancer diagnosis and treatment and implementing nursing initiatives aimed at reducing the symptoms, knowing the importance of life quality, maintaining measures aimed at life quality and planning initiatives to increase the life quality will play a key role in maintaining and developing the health of Turkish paediatric oncology patients and their parents.

Recognition of the usefulness and the importance of the nursing diagnosis is increasing. There is a prevailing opinion that nursing diagnosis should be used to improve the quality of nursing care. Developing standardized nursing care palns based on nursing diagnoses is therefore considered one of the most essential projects for professional growth and improvement in the nursing world of Korea. Consequently, in the first stage of this research project, the ten nursing diagnses used most frequently with patients on medical and surgical wards were determined and related nursing care plans were developed, implemented and evaluated. The application of the standardized nursing care plans raised the nurses' confidence and proved to be effective in enhancing the quality of nursing care. This study was initiated as the next stage, to develop, test, and determine the validity of nursing care plans for the remaining nursing diagnoses. Nineteen medical and surgical wards were selected for the study ; the 176 staff nurses working on those wards and 1211 patients hospitalized there (603 patients during the nursing care plan use) took part in the project. The following summarizes the results of the study : 1. After listing all the nursing diagnoses up to the 20th in frequency from each ward except the ten used in the first study, 22 nursing diagnoses were selected. Two related to ‘self care deficit’, were combined into one. Standardized nursing care plans were established for these 21 nursing diagnoses. 2. The first page of each nursing care plan lists the related factors and defining characteristics as supporting data. The application rate distribution revealed that the majority were recorded less than 50% of the time. For each nursing diagnosis, only one to three related factors were recorded more than 50% of the time regardless of the number of suggested related factors, and similarly, only one to five defining characteristics were recorded more than 50% of the time regardless of the number of suggested defining characteristics. Therefore, these factors and defining characteristics were proposed as the common related factors and the typical signs and symptoms for each nursing diagnosis. 3. The application rate distribution for the expected outcomes, and the nursing orders that were the main data of each nursing care plan occurred more than 50% of the time, unlike the related factors and the characteristics that occurred less frequently. These findings supported the clinical validity. 4. In an effort to evaluate indirectly the effect of the use of the standardized nursing care plans, nurses' job satisfaction and perceptions of their ability in the use of the nursing process were measured and compared. Scores after the use of the plans were significantly higher than those before. The experience in actually using the standardized nursing care plans with patients increased the nurses' professional and emotional satisfaction and their confidence in using the nursing process. Also when the nurses who actually used the nursing care plans were asked to rate their effectiveness, the highest score was given to ‘the ease of establishing the nursing goal’, followed by ‘improved professional advice and care for patients’, ‘the efficiency and systemization of charting’, ‘the definite recognition of the nursing problem’, and ‘the selection of effective and appropriate nursing interventions’ in descending order. The results indicate the nurses were very positive about the effect of the real clinical application of standardized nursing care plans, and that the objective of this study to utilize the nursing diagnosis to strengthen the nursing process was attained.

Via the Internet, the information infrastructure of modern health care has already established medical information systems to share electronic health records among patients and health care providers. Data hiding plays an important role to protect medical images. Because modern medical devices have improved, high resolutions of medical images are provided to detect early diseases. The high quality medical images are used to recognize complicated anatomical structures such as soft tissues, muscles, and internal organs to support diagnosis of diseases. For instance, 16-bit depth medical images will provide 65,536 discrete levels to show more details of anatomical structures. In general, the feature of low utilization rate of intensity in 16-bit depth will be utilized to handle overflow/underflow problem. Nowadays, most of data hiding algorithms are still experimenting on 8-bit depth medical images. We proposed a novel reversible data hiding scheme testing on 16-bit depth CT and MRI medical image. And the peak point and zero point of a histogram are applied to embed secret message k bits without salt-and-pepper.
