Purpose: The purpose of this study was to develop a tool that measures the quality of nursing service, to measure the quality of nursing service perceived by consumers, and to identify the gaps between ideal and actual nursing services. Method: A questionnaire was developed and distributed to 300 people who had been hospitalized in one of six general hospitals with quality of nursing services in five provincial cities in Korea. For data analysis, the SPSS/WIN(ver 10.0) program was used. Result: The 20 attributes included in the instrument of quality of nursing service is abstracted into 2 factors: tangibility and intangibility. In quality analysis, 15 of 20 attributes are minus scores, meaning that those nursing services are perceived as generally low. However among the minus scores' attributes, only two attributes are significant statistically. Gaps between importance and performance of the nursing service exists in 19 among 20 attributes. Conclusion: Nursing service quality (performance-expectation) needs to be improved, and Gaps (importance-performance) reduced. In addition, a tool measuring nursing service quality has to be developed so nurses can deal successfully with the quality and gaps of nursing service perceived by consumers.

Purpose: The purpose of this study was to identify effectiveness of fundamental nursing practices in clinical settings. Method: This study adopted the triangulation method. Using one group pre-post test design, this study identified differences in self efficacy between pre and post clinical practice. The study was also designed to describe the nursing student's experience of clinical practice by using content analysis Results: 1) All students experienced bedmaking, BST check, V/C check, positioning, transferring, assisting with moving and positioning, and ROM. Sixty percent of students experienced giving oral care, and forty percent experienced shampooing patient's hair. 2) While the mean score of self efficacy was 3.88 in the pre-test, it decreased to 3.76 in the post-test. They were statistically different from each other. 3) Seven categories were elicited from the result of content analysis on the nursing student's experience, which were 'ignorant stranger', 'facing the gap between theory and practice', 'resolving the uncertainty of clinical setting', 'getting used to fundamental nursing practice', 'motivated by a desire to study and self-development', 'understanding the nursing profession's job', and 'being helpful for the future career'. Conclusion: Fundamental nursing practice in clinical settings is a useful strategy that improves fundamental nursing skills and motivates student's self-development.

There have been so many studies related to job stress or musculoskeletal disorders(MSDs) in the shipbuilding industry. However, study of employee performance evaluation that reflect on the industrial features of the deckhouse manufacturing industry has not been established. Therefore, this study aimed to evaluate workers' job stress and work ability through statistical significance tests according to age, work types, years of service, work forms and sex. For this, the study conducted a job stress test using the Korean Occupational Stress Questionnaire Short Form, and employee performance evaluations using the Work Ability Index(WAI) of the Finnish Institute of Occupational Health (FIOH) on 536 workers in the deckhouse manufacturing industry. MINITAB statistics program was used for statistics analysis and significance was verified with the Kruskal-Wallis test, a corporate body of nonparametric statistical analysis. As a result, employee performance had significant differences, depending on age, work types, years of service and sex, and job stress also depended on the number of service year and work form. Additionally, it was found that employee performance decreased more as job stress increased.

Limited fossil fuels and unstable energy supply are considered as one of the critical problems in architecture requiring large amounts of energy. In order to this challenge, environment-friendly architecture design is required. Clear data should be prepared to apply solar energy to architecture aggressively and properly. This study used FS statistical analysis data regarding average daily solar radiation of Seoul observed over 20 years to find out standard year and standard daily solar radiation. This study also aims to compare and evaluate an appropriate method of selecting a standard year which is too close to measurement value through comparison and analysis with daily solar radiation acquired by applying overseas researchers' suggesting weight factor. As a result, the data nearest to measurement value of daily solar radiation was UK CIBSE TRY(TYPE 2) displaying 0.100in t-statistic index. For UK CIBSE TRY(TYPE 2), weight factor was applied to three climatic elements except relative humidity. TYPE 1 and TYPE 3 recorded 0.343 and 0.367, respectively, showing higher record of t-statistic than TYPE 2. TYPE 1 was calculated through FS statistical value of single data about daily solar radiation with other climatic elements excluded. For TYPE 3, relative humidity was added to TYPE 2. In particular, since TYPE 2 was closer to the measurement value compared to the others, it is necessary to consider relationship with other climate elements if other climate elements are added.

Objectives: We sought to evaluate the mitigating effect of using floss and interdental brushes on periodontal health inequality. Methods: This study was based on data acquired from the Seventh Korea National Health and Nutrition Examination Survey (KNHANES VII; 2016-2018). We included 11,359 participants aged ≥19 years in the final analysis. Multivariable logistic regression analysis was performed using socioeconomic characteristics, health behavior, health status, and periodontitis status. We analyzed differences in the prevalence of periodontitis according to household income stratified by the use of floss and interdental brush. Results: In the multivariable logistic regression model, the lowest income group had 1.304 (95% confidence interval [CI] 1.08-1.58) odds ratios for periodontitis than the highest income group. In the interdental brush nonusers or floss nonusers, the lowest income group had significantly higher odds of developing periodontitis. However, we found no significant differences in the periodontitis prevalence between the income groups among the interdental brush users. In the 65-year-old or older group, the same result was observed in the interdental brush and floss users. Conclusions: The results suggest that the use of floss and interdental brushes could alleviate periodontal health inequality.

Governmental bodies generally conduct investigations for product safety management once new products are released to the market, in order to prevent distribution of illegal and defective items. Further, market surveillance activities are regularly conducted by the government to ensure distribution of safe products and recall any hazardous products. The safety investigations often involve a consumer monitoring system wherein consumer organizations participate in market monitoring to conduct surveys on illegal and defective products. As a result, the monitoring results of individual consumer organizations are available separately, but an integrated analysis of the data from all consumer organizations cannot be performed, thereby deterring comprehensive evaluation of the consumer monitoring system. In this study, we analyze the individual monitoring results of consumer organizations to understand the overall status and performance of comprehensive market monitoring and present the directions for desirable market surveillance policies. To this end, the effectiveness of market surveillance related to the distribution of products is verified through analysis of the interrelationships between the monitoring processes and performances of consumer organizations as well as their impact on the performances of the monitoring implementation processes; moreover, several improvement points and direction points are presented for more desirable monitoring of the consumer markets.

Recently, steel-timber hybrid buildings have become prevalent worldwide because several advantages of both steel and timber structures are maintained in the hybrid system. In Taiwan, seismic design specification related to steel-timber hybrid buildings remains void. In this study, the ductility capacity of steel-timber hybrid buildings in Taiwanese seismic design specification is first proposed and evaluated using nonlinear incremental dynamic analysis (IDA). Three non-linear structural models, 12-story, 8-story, and 6-story steel-timer hybrid buildings were constructed using OpenSees. In each model, Douglas-fir was adopted to assemble the upper 4 stories as a timber structure while a conventional steel moment-resisting frame was designated in the lower part of the model. FEMA P-695 methodology was employed to perform IDAs considering 44 earthquakes to assess if the ductility capacity of steel-timber hybrid building is appropriate. The analytical results indicate that the current ductility capacity of steel moment-resisting frames can be directly applied to steel-timber hybrid buildings if the drift ratio of each story under the seismic design force for buildings in Taiwan is less than 0.3%. As a result, engineers are able to design a steel-timber hybrid building straightforwardly by following current design specification. Otherwise, the ductility capacity of steel-timber hybrid buildings must be modified which depends on further studies in the future.

The purpose of this study is to analyze the characteristic of quality attributes of smart hotels by using a SERVQUAL-IPA model, focusing on Chinese, which has the most proactive approach for the adoption of smart hotel system. Toward this goal, six quality factors-tangibles, reliability, assurance, responsiveness, empathy, and playfulness-were extracted through factor analysis, and IPA was used to appraise the degree of importance and satisfaction for each quality attribute. As a result of the SERVQUAL-IPA model, quality attributes were categorized into four groups of 'keep up the good work,' 'possible overkill,' 'low priority,' and 'concentrate here.'. Furthermore, it was concluded that there is a need to focus on the following elements: 'smart devices can assist customers in emergency situations', 'when the room control system identifies customer needs, the staff can provide prompt service', 'development and improvement of mobile applications that enable customers to control room amenities', 'regular maintenance for smart devices', and 'providing data-driven personalized recommendations through customer activity data analysis'.

It generally accepted that most building structures shall exhibit a nonlinear response when subjected to medium-high intensity earthquakes. It is currently known, however, that this phenomenon is not properly modelled in the majority of cases, especially at the design stage, where only simple linear methods have effectively been used. Recently, as a result of the exponential progress of computational tools, nonlinear modelling and analysis have gradually been brought to a more promising level. A wide range of modelling alternatives developed over the years is hence at the designer's disposal for the seismic design and assessment of engineering structures. The objective of the study presented herein is to test some of these models in an existing structure, and observe their performance in nonlinear static and dynamic analyses. This evaluation is done by the use of two of a known range of advanced computer programs: SAP2000 and SeismoStruct. The different models will focus on the element flexural mechanism with both lumped and distributed plasticity element models. In order to appraise the reliability and feasibility of each alternative, the programs capabilities and the amount of labour and time required for modelling and performing the analyses are also discussed. The results obtained show the difficulties that may be met, not only in performing nonlinear analyses, but also on their dependency on both the chosen nonlinear structural models and the adopted computer programs. It is then suggested that these procedures should only be used by experienced designers, provided that they are aware of these difficulties and with a critical stance towards the result of the analyses.
