The Korean government has made it a major national task to contribute to the revitalization of the creative economy, such as creating new industries and jobs, by encouraging the private opening and utilization of public data. The Korean government is promoting public data quality improvement through activities such as conducting public data quality management level evaluation for high-quality public data retention. However, there is a difference in diagnosis results depending on the understanding and data expertise of users of the public data quality diagnosis tool. Therefore, it is difficult to ensure the accuracy of the diagnosis results. This paper proposes a public data quality management level evaluation domain rule mapping model applicable to validation diagnosis among the data quality diagnosis standards. This increases the stability and accuracy of public data quality diagnosis.

This study investigated if a requirement for screen gloss is needed in the TCO Requirements and was, therefore, targeted towards finding an acceptable reflex level. The results show that a glossy surface has an impact on the visual ergonomics, and for this reason we believe that a requirement is needed. Although, the results do not point to a single value that is better than another, so a selection for a requirement level has to be augmented with additional information. Such a discussion is given and 60 gloss units at 60 degrees ($GU_{60}$) was selected as the new requirement level for the TCO Requirements (TCO '03 and TCO '05).

This paper aims to develop the adequate quality cost model at a company which delivers ICT(information communication technology) services. One particular business unit was in the first instance selected and quality costs were then analysed at an organization level, for a department and for specific processes. Some areas were determined for quality improvement at each level and their causes were also investigated. However, the existing PAF(prevention, appraisal and failure) models reveled some limitations because the ICT services company included the different number of large and complicated business processes. The PAF model did not sufficiently highlight the detailed causes of failure costs. It did not also stimulate the relevant department's strong responsibility to improve such problems. Both micro PAF and process cost models were proposed in order to cope with this. In final, it explains the relationship between six sigma and quality costing, suggesting how to use the quality costing results as a means of promoting either continuous improvement or innovation in a case company.

Purpose: The purpose of this study was to examine the relationships among sexual function, sexual stress, and quality of life in middle aged women patients with diabetes mellitus. Methods: Data were collected through questionnaires distributed to 154 middle aged women patient with diabetes mellitus in one hospital. Results: The mean sexual function score was $12.99{\pm}9.11$. There were statistically significant differences in sexual function according to age, level of education, employment status, time of being diagnosed with diabetes mellitus, number of complications, self-monitoring of blood glucose, menopausal status, and level of glycosylated hemoglobin. The mean sexual stress score was $26.99{\pm}16.88$. The score of quality of life was $79.12{\pm}14.30$. There were statistically significant differences in quality of life according to level of education. Sexual function was negatively correlated with sexual stress (r=-.46 p<.001) and positively correlated with quality of life (r=.32, p<.001), while sexual stress was negatively correlated with quality of life (r=-.36 p<.001). Conclusion: Higher sexual dysfunction in middle aged women patients with diabetes mellitus was correlated with lower sexual stress and improved quality of life, while lower sexual stress was correlated with improved quality of life.

This study was attempted to identify the effects of physical and mental health on quality of life in middle-aged adults by gender. The Data were analyzed for 4,511 adults (2,260 men, 2,251 women) aged 45 to 65 who had no missing values in major variables based on the data of the 2016 Korea Health Panel. According to the data, the quality of life in middle-aged adults was .92 (±.08) for men and .91 (±.10) for women, which was significantly higher than that of women (t=3.54, p<.001). Factors affecting the quality of life in middle-aged men were subjective health status (β=.40, p<.001), stress (β=-.17, p<.001) and education level (β=.10, p<.001), and these variables explained 23% of the quality of life (F=227.28, p<.001). Factors affecting the quality of life in middle-aged women were subjective health status (β=.40, p<.001), stress (β=-.11, p<.001), education level (β=.05, p=.011) and anxiety (β=-.05, p=.022), and these variables explained 21% of the quality of life (F=145.42, p<.001). Based on the results of this study, the group with low level of education in middle-aged adults needs health management, education on how to relieve stress, and intensive management to improve the quality of life. In addition, the differentiated approach should be required to reduce anxiety in middle-aged women.

Purpose - Because it is not possible to assess the quality of service products before experiencing them, one feature of a service product is quality uncertainty; hence consumers may react sensitively to pricing. It is necessary to investigate how different pricing strategies affect consumer purchase intention depending on the level of service quality uncertainty. Research design, data, and methodology - The authors have investigated the potential impact of the level of service quality uncertainty, price discount rate and presentation method on consumer purchase intention. A play was selected as an experimental stimulus, and Vietnamese consumers were surveyed to verify the hypotheses. Results - When uncertainty regarding service quality is low, consumer purchase intention is higher when the price discount rate is high or when the price is low. When uncertainty regarding service quality is high, if the normal price, discount rate, and discounted price are presented simultaneously, consumer purchase intention is higher when the price discount rate is low, but when only the discounted price is presented, purchase intention is higher when the price discount rate is high. Conclusions - The results of this study can provide valuable practical implications for pricing for service products with quality uncertainty.

We compared a novel encoding Lempel-Ziv complexity (ELZC) with three common complexity algorithms i.e., approximate entropy (ApEn), sample entropy (SampEn), and classic Lempel-Ziv complexity (CLZC) so as to determine a satisfied complexity and its corresponding quality indices for assessing quality of multi-lead electrocardiogram (ECG). First, we calculated the aforementioned algorithms on six artificial time series in order to compare their performance in terms of discerning randomness and the inherent irregularity within time series. Then, for analyzing sensitivity of the algorithms to content level of different noises within the ECG, we investigated their change trend in five artificial synthetic noisy ECGs containing different noises at several signal noise ratios. Finally, three quality indices based on the ELZC of the multi-lead ECG were proposed to assess the quality of 862 real 12-lead ECGs from the MIT databases. The results showed the ELZC could discern randomness and the inherent irregularity within six artificial time series, and also reflect content level of different noises within five artificial synthetic ECGs. The results indicated the AUCs of three quality indices of the ELZC had statistical significance (>0.500). The ELZC and its corresponding three indices were more suitable for multi-lead ECG quality assessment than the other three algorithms.

Purpose: The purpose of this study was to identify the relationship between self reported climacteric symptoms, and depression, and the quality of life in middle aged women. Method: The subjects of this study were 149 women from 40 to 64 years of age. Climacteric symptoms were measured with Neugarton's tool(1965) and depression with Zung's tool. Quality of life was related to self reported climacteric symptoms were education level (F=3.011, p=.035), income measured by Rho's tool(1988). Result: The general characteristic variables significantly level (F=2.670, p=.057), income satisfaction (F=3.413. p=.011), perceived subjective health condition(F=28.623, p=.000). The general characteristic variables significantly related to depression were age(t=-2.476, p=.014), education level (F=4.492, p.013). income satisfaction (F=2.845, p.026), perceived subjective health condition (F = 8.468, p=.000). The general characteristics variables significantly related to quality of life were income level (F= 5.010, p=.000), income satisfaction (F=6.314, p=.000), perceived subjective health condition (F=3.516, p<=.032). menstruation cycles(t=-2.66, p=.023). The relationship between self reported climacteric symptoms and depression had a statistically a positive correlation (r=.357, p=.000). The relationship between depression and quality of life had a statistically with a negative correlation(r=-.397, p=.000). Conclusion: These results may contribute to a better understanding of depression and quality of life in middle aged women. Therefore, health programs for prompting climacteric women´s health should be a planned based on results of the study.

To find out the optimum mixing level of wheat bran to improve the quality of 1st cut Alfalfa silage, this trial was canied out at two-year's Alfalfa monoculture field of the National Livestock Research Institute, Suwon, Korea, from May 1955 to Oct. 1995. The results are as follows. I. According to the increase of wheat bran mixing level, DM content was high from 23.19%(nil) to 35.70%(40% mixing), pH of silage were low from 5.51(nil) to 4.45(40% mixing). but there were not significant at 20% mixing or more(P>0.05). 2. Also it was appeared to the same trend at Lactic acid content and in the Flieg's score of silage it was highest as 59 in the 20% mixing level. 3. In chemical component of silages there were not significant at 20% mixing or more in crude protein, crude fiber and ashes content, 30% mixing or more in ether extract and 10% or less in NFE content(P>0.05). 4. TDN, NEL and StE contents were low as adding level was increased. respectively, but there were not significant(P>O.OS). As mentioned above the results, desirable mixing level of wheat bran to lstcut Alfalfa to improve the quality of silage was 20% of fresh weight.
