Purpose: The purpose of this study was to develop an Allergic Rhinitis-Specific Quality of Life (ARSQOL) scale and verify its validity and reliability. Methods: ARSQOL was developed in 5 steps. Items for the preliminary instrument of ARSQOL were developed through a literature review and deep interviews with allergic rhinitis patients. Face validity with Content Validity Index (CVI), construct validity using factor analysis, and known group comparison, criterion validity test using correlation between ARSQOL and total nasal symptoms score (TNSS) were conducted to evaluate the validity of ARSQOL. Cronbach's ${\alpha}$ was used to evaluate the reliability of ARSQOL. Results: CVI for the items in the final ARSQOL were. 92. Five factors including discomfort associated with nasal symptoms (4 items), physical function (7 items), mental function (5 items), sleep disorder and social function (4 items), and problems of daily life (6 items) were identified through factor analysis and these five factors explained 66.6% of the total variance. The correlation coefficient between TNSS and the total score of life quality was -.69. In the group comparison, the persistent allergic rhinitis group showed lower ARSQOL scores than the intermittent patient group, and moderate to the severe allergic rhinitis patient group presented poorer ARSQOL than the mild symptom patient group. The Cronbach's ${\alpha}$ reliability coefficient was .95. Conclusion: Results show that the ARSQOL has good reliability and validity and thus ARSQOL is a useful scale for clinical practices and research as a measure of quality of life in adults with allergicr hinitis.

Most current design codes of concrete structures adopt the partial safety factor format to assure the proper safety margin or reliability against various limit states as a practical design tool. The safety factors, load and resistance factors and so on, are determined based on the theory of structural reliability, which takes into account the statistical uncertainties of both loads and resistances. The establishment of statistical models for load and resistance should be preceded the application of reliability theory. In this paper, especially the influence of the statistical variations of resistance models, which are described in terms of strength of concrete, strength of reinforcements and sectional dimensions and so on, are examined and the probabilistic models for resistance of reinforced concrete members were developed. The statistical data were collected on local tests and experiments in Korea and the Monte Carlo simulation (MCS) technique was used. The results of this paper may be useful and valuable in calibration of design code in this country.

Purpose: To test the reliability and validity of the Korean version of the Person-centered Climate Questionnaire-staff version (KPCQ-S) in long-term care institutions. Methods: A total of 297 staff in long-term care institutions including nine nursing homes (NHs) and 4 long-term care hospitals (LTCHs) were included. The KPCQ-S was developed following the WHO guidelines of the process of translation and adaptation of instruments. An internal consistency using Cronbach's ${\alpha}$ was tested for reliability. Exploratory factor analysis (EFA) was used to examine the construct validity. Convergent and discriminant validity were examined using Pearson correlation. Results: EFA demonstrated the construct validity of the 14-item KPCQ-S with three-factor solutions, specifically three factors (safety, everydayness, and community) in NHs and four factors (safety, everydayness, community, and comprehensibility) in LTCHs. Convergent validity was found in the correlation with the work satisfaction (r=.55). The KPCQ-S showed satisfactory internal consistency reliability (Cronbach's ${\alpha}=.91$). Conclusion: The KPCQ-S is found to be a reliable and valid tool for measuring staff perceptions of the person centeredness of long-term care environments.

Purpose: The aim of this study was to develop and test the validity and reliability of the Korean version of the Pre-Menstrual Coping Measure (PMCM-K). Methods: Translation of the PMCM-K was validated using forward-backward translation methods. The study was conducted as a cross-sectional survey from March 7 to April 30, 2016 and the data from a total of 362 young adult women were used for the final analysis. The content validity, construct validity and criterion-related validity were evaluated. The internal consistency was calculated to assess the reliability. Results: The PMCM-K consisted of five factors: premenstrual coping regarding avoiding harm, awareness and acceptance of premenstrual change, self-care, communicating, and adjusting energy, which all explained 62.0% of the total variance in PMCM-K. The total score of the PMCM-K showed a positive correlation with the shortened premenstrual assessment form (r=.50). The Cronbach's alpha reliability coefficient was .94 for the overall instrument and .77-.93 for five factors. Conclusion: PMCM-K provides a valid and reliable scale for quantifying the ways of coping specific to a negative premenstrual change for Korean young adult women. The PMCM-K will play an important role as a way to gain a sense of agency in coping with premenstrual changes.

This study is aimed to assess the general population's attitude toward the continuity of medical care and its related factors. Self administered questionnaire was performed on the 1,120 office workers in the C city, Gang-won province. The questionnaire included the attitude of the continuity of medical institute, the intention of medical service use on a given case, and the variables of the related factors. 58.8% of the total respondents agreed to sustaining treatment without changing medical institutes; on the other hand, 41.2% showed negative attitude. In case that a patient would gain a recommendation of a surgery, hospitalization, or a specific examination, the total respondents' 84.9%, 61.8%, and 50.8% of each recommended situation said that they would visit another doctor and gain a diagnosis. As a result of multiple logistic analysis of determinant factor on continuity, reliability of doctors was statistically significant factor. In order to reduce wastefully used medical resources and offer well-qualified medical service, a system of second opinion among peer group or beforehand agreement could be possibly adopted. In addition, improving the image and reliability of a doctor could be an important factor to make better the behavior of medical service shopping; therefore, an effort to improve the relationship between a doctor and a patient, and restore the reliability of doctors should be paralleled.

This study aims to present a direction for securing continuous growth and confidence, centering on two Internet banking companies that started recently. The banking market has been rewriting the history since the emergence of Internet professional banks. In order to improve the credibility and promote the development of the Internet professional banks, I conducted a questionnaire survey and In Depth Interview. As a result of this survey, the overall reliability is still low, and the factors affecting reliability are: 1.Security problem 2.Discomfort of customer service 3.Errors and unnecessary services. This is a start-up business, so the awareness and reliability can be changed soon. Therefore, it is necessary to continue research on this according to the changing user's perception.

In this paper, a probability-based reliability analysis was proposed based on a finite element method-based random vibration analysis and serviceability limit state of structures. The limit state model defined for the study is a serviceability limit state in terms of the more realistic crack failure that might cause the emission of radioactive materials. The SAP V-2 is used for a three-dimensional finite element analysis of concrete containment structure, and the reliability analysis is carried out by modifying HRAS reliability analysis program for this study. In this study, the load factors for the design of reinforced concrete cointainment structures in Korea are proposed by considering appropriate load combination criteria for design, and the results are compared with the present ASME code. The proposed load factors were proved to be in accordance with a set of code performance objective and showed consistency in the limit state probability.

The reliability of hydraulic equipment used in power plants is especially important because failures that occur in the power plant can have a great ripple effect on human lives and financial losses. In this study, specimens using the materials used in the spool and sleeve of hydraulic valves of power plants have been produced, heat-treated, and tested under the precipitation conditions of phosphate ester hydraulic fluid with a variety of conditions. 23 full factorial designs have been applied to evaluate the significance of factors that affect the wear loss of the specimen, specifically, the load, velocity, and temperature. The significance evaluation was performed on the main effects and two-way interactions for wear loss based on the experiment results, and the mathematical equations between the wear loss and the three factors were derived from the analysis results.

The main purpose of this study was to develop and validate a scale for measuring situation\ulcornerspecific anxiety that consumers experience while shopping for ready\ulcornerto-wear clothes. A 92 five-point items, Likert type scale, entitled the RMCCAS(The Ready\ulcornerMade Clothes Consumer Anxiety Scale) was developed and administered to 354 female college students. Data collected were subjected to a series of statistical analysis: item analysis, factor analysis, estimation of validity and reliability and descriptive statistics. A second-order factor analysis conducted to 15 factors obtained from a first-order factor analysis yieled three factors; Fitness of Fashion and Design to indiviuality and time(scale 1), Reliance on Price and Quality including Suitableness of Material and Color(scale 2), and Practicality in Dressing and Maintaining(scale 3). Obtained concurrent validity of the RMCCAS subscales with the trait anxiety were .056(subscale I), .082(subscale 2), .033(subscale 3), and .050(total scale). that with state anxiety were .421(subscale I), .217(subscale 2), .198 (subscale 3), and .407(total scale); that with the CP AS were. 721(subscale 1), .789(subscale 2), .570(subscale 3), and .841(total scale). All of the obtained coefficients of Cronbach alpha, split\ulcornerhalf reliability, and test-retested reliability over an interval of. 8 weeks were above .80. Besides, descriptive data from the RMCCAS satisfactorily supported conditions required for the normal distribution of obtained scores. In conclusion, a close exa:nination of validity, reliability, and descriptive statistics of the RMCCAS indicates that three subscales including the scale have a resonable scaling-prop\ulcornererties. Further research is suggested for obtaining norms for more representative target samples and for tapping the possibility of using subsea Ie 2 as a unidimensional measure .
