Diatoms have become an integral part of the UK's freshwater monitoring strategy over the past two decades, mostly in response to increasingly stringent European Union (EU) legislation. The use of diatoms is based on strong correlations between diatom assemblages and environmental variables, and from knowledge of the "expected" (= "reference") state of each river. The nationwide overview of the ecological health of rivers this gives allows those stretches of rivers which fail to meet EU criteria to be identified. This, in turn, allows appropriate remediation measures to be planned. Because diatom assemblages vary in space and time, even within a single water body, effective use of diatoms requires a consistent approach in order to minimise uncertainty. This includes the use of methods which comply with European Standards, a training and accreditation scheme for analysts, and a suite of quality assurance methods. Those aspects of uncertainty that cannot be readily controlled have been quantified and all estimates of ecological status are accompanied by the appropriate "confidence of class" and "risk of misclassification". This, in turn, helps planners prioritise those locations which are most likely to benefit from remediation.

Purpose: This study was to identify health behavior, health service use, and health related quality of life of adult women in one-person and multi-person households. Methods: It was used data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-2017). Subjects were 2,522 women with age of 19 to 64 years in 2017. Complex sampling design and data analysis were performed using SPSS 20.1. Results: Women in one-person households had higher rates of alcohol drinking (${\chi}^2=13.77$, p=.003), smoking (${\chi}^2=16.07$, p=.001), unmet medical care (${\chi}^2=8.77$, p=.004) and non-practice of cancer screening (${\chi}^2=13.77$, p=.003) compared to women in multi-person households. Health-related quality of life was also lower for women in one-person households (t=-2.46, p=.015). Factors affecting health-related quality of life in one-person households were household income, job status, and unmet dental care, having 32.4% explanatory power. One-person household women with low incomes, no jobs, and unmet dental care showed low health-related quality of life. In comparison, factors affecting health-related quality of life of women in multi-person household women were age, education level, unmet medical care, and unmet dental care, having 10.4% explaining power. Women in multi-person households with age of 60-64, low education level, unmet medical care, and unmet dental care showed low health-related quality of life. Conclusion: Health promotion strategies should be developed based on unique understanding of social, economic, and health of adult women in one-person and multi-person households.

Objective: The purpose of the present study was to examine the relationship between the use of senior center and health-related quality of life in Korean older adults. Methods: A questionnaire survey was conducted to two types of older adults who lived in Busan, Korea: 154 older adults who used a senior center and 137 older adults who did not use a senior center. The Korean version of short-form 36-item health survey was administered to assess the health-related quality of life. Demographic variables were obtained from a questionnaire. These were gender, age, family status, marital status, education, monthly income, present illness, body mass index and physical activity. Results: The 8-domain scales of physical function and role-physical were significantly higher in the users of the senior center compared with the non-users (F=4.87, p=0.027 and F=7.02, p=0.009, respectively). The 8-domain scales of vitality was also significantly higher in the users of the senior center compared with the non-users (F=7.48, p=0.007). Conclusions: The present study showed that the users of the senior center have higher physical function, role-physical and vitality compared with the non-users. These findings suggest that although the results are unable to specify causal relationships using the senior center may lead to some improvement in health-related quality of life.

Purpose : This study was to compare and analyze major factors related to smartphone addiction according to the gender of health-related college students. Methods : 720 people who voluntarily participated and agreed to fill out the questionnaire were randomly sampled. Smartphone addiction was measured using the Smartphone Addiction Scale Short Version (SAS-SV), sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), anxiety symptoms were measured using the self-assessment anxiety scale (SAS), and depression symptoms were measured using the self-assessment depression scale (SDS). In addition, the age of each individual and the main function of smartphone use were also investigated. Results : The prevalence of smartphone addiction was higher among female students than male students (p<.05), while male students mainly played games and female students mainly used multimedia (video/music) viewing and social networking services (p<.05). In addition, male students showed a high association with smartphone addiction in the group where games were the main function of smartphone use, the group with low sleep quality, and the group with anxiety symptoms (p<.05), but for female students, multimedia (video/music) Or, the group in which social networking service is the main function of smartphone use, the group with low sleep quality, and the group with symptoms of anxiety and depression showed a high correlation with smartphone addiction (p<.05). Conclusion : It is expected that the results of this study will be used as basic data for providing customized solutions considering the characteristics of smartphone addicts.

In this Paper, We study on establish for unit of measure. Quality means abstract for customer needs. we surveyed unit of measurement of quality feature of Juran, Taguchi, 6 sigma method. We suggest unit of measurement of quality feature. Each enterprise can use defining own unit of measurement of quality feature. Effect is expected in enterprise that these proposals do quality control. There is meaning in direction that measuring mean of quality feature that propose in this treatise understands actuality to be deeply and reconcile exact point of theory.

To investigate the impacts of ISO 9000 QA systems to the Korean industry quality improvement as well as quality consciousness, QA related data has been surveyed from quality assurance engineers who have worked on ISO 9000 certification activities and has been analyzed using relevant tabulations of five(5) scale or x2-homogeneity test method. Hypotheses to the unchange in the quality consciousness are tested in terms of x2-homogeneity in order to compare the consciousness of pre-certification with that of post-certification. The level of quality management of Korean manufacturing industry has been high-lighted by use of quality maturity grid.

기존 유통기업과 플랫폼을 중심으로 한 신생기업들이 언택트 쇼핑에서 만나면서, 언택트 쇼핑 안에서 기업들의 경쟁이 더욱 치열해지고 있다. 이러한 상황에서 기업들은 자사만의 확실한 전략이 필요하다. 언택트 쇼핑에서 전략을 수립하기 위해서는 '고객경험'을 살펴보는 것이 매우 중요하다. 고객경험은 소비자가 기업이나 브랜드 등을 서비스 접점에서 만나 경험하는 모든 과정을 의미한다. 이 과정에서 소비자는 해당 기업과 브랜드를 지속이용 할 것인지를 판단한다. 본 연구는 언택트 쇼핑의 고객경험을 경험 품질을 통해 살펴보고, 기대일치 모델에 미치는 영향을 살펴보고자 하였다. 본 연구의 중요한 결과는 다음과 같다. 첫째 상호작용품질, 정보품질, 결과품질이 기대일치에 영향을 미치는지 살펴본 결과 상호작용품질을 제외한 모든 품질이 기대일치에 영향을 미치는 것으로 나타났다. 둘째 상호작용품질, 정보품질, 결과품질이 지각된 유용성에 영향을 미치는지 살펴본 결과 역시, 상호작용 품질을 제외한 모든 품질이 영향을 미치는 것으로 나타났다. 결과를 살펴보면 정보품질이 가장 크게 영향을 미치는 것으로 나타났다. 이는 언택트 쇼핑을 이용하는 소비자의 기대일치, 지각된 유용성 등을 충족하기 위해서는 정확하고 적합한 정보를 제공하는 것이 가장 중요하다는 것을 알 수 있다. 다음으로 기대일치 모델 내에서 기대일치가 지각된 유용성에 영향을 미치는지 살펴본 결과, 영향을 미치는 것을 알 수 있다. 또한 기대일치가 이용만족에도 영향을 미친다는 것을 알 수 있으며, 지각된 유용성이 이용만족에도 지지 되는 것을 확인 할 수 있다. 따라서 언택트 쇼핑에 관련된 고객경험 전략을 수립할 때 정보품질, 기대일치, 지각된 유용성이 가장 중요한 요인이기 때문에 이를 중심으로 관련된 전략을 수립하는 것이 필요하겠다.
