The purpose of this study was to identify the influencing factors of subjective health status among the subjects of the 7th year 3 (2018) National Health and Nutrition Examination Survey, and to help provide programs for improving subjective health status in the future. Data from the 7th Korea National Health and Nutrition Examination Survey(2018) were used. Variables were age, gender, age, subjective health status, subjective body shape recognition, weight change over the past year, usual stress level, walking days per week, and strength training days per week. The higher the number of walking days per week, the lower the usual stress perception level. As the number of strength training days per week increased, the level of stress perception was lower (p<.001). The subjects' subjective health status was found to have a negative effect on their usual stress perception (β=-.759), subjective body shape (β=.111), age (β=.421), and number of days walking per week. (β=.968). Based on this study, it is intended to provide basic data for preparing programs to help improve stress perception and subjective health status in the future.

Purpose - Not all firms are able to completely eliminate the risk arising out of the crisis. Success hides in the ability to perceive the market expectations accurately and take correct decisions. This study aims to analyze the firms' decisions at gross-root level. Research Design, Data, and Methodology - Primary data is obtained with the help of specially designed questionnaires from the agriproducts export firms that are members of export union of Turkey. The study is based on four theoretical structures: general planned behavior theory model, perception-leading behavior control and subjective norm model, perceived-behavioral-control leading perception and subjective norm models, and perceptions and subjective norms leading behavior control model. Structural Equation Models (SEM) is used to conduct the empirical analysis. Results - The findings show perceptions and subjective norms leading behavior control model as the best one, concluding that the environmental pressures and positive perceptions have significant effect on the strategic decisions of the agriproducts export firms. Conclusion - Policy tools like creating positive perception in the markets, providing sufficient information and financial support to the firms and increasing market competition can be used effectively to achieve the said objective.

The purpose of this study was to investigate the effects of heat transfer characteristics of fibers on the Qmax of insulating nonwovens. The effects of fiber type, moisture content, washing cycles on the Qmax were observed. The correlations between Qmax measured by KES-F7 system and subjective warm/cool touch perception test was analyzed. The results obtained were as followed: 1. Heat transfer characteristics of fibers effected on the Qmax of insulating nonwovens. 2. Moisture transport properties of fibers effected considerably on the Qmax of nonwovens and the increasing rate of Qmax by increasing moisture content was much higher at wool than polyester. 3. As a result of subjective perception test, subjective warm/cool touch and wettness of wool nonwoven was increased obviously by increasing moisture content. 4. At the same moisture content, wool nonwoven showed higher subjective cool touch and wetness than polyester. 5. In the physical properties of nonwovens, thickness was the most effective factor on the Qmax of insulating nonwovens.

The conventional methods for noise control attempts to simply reduce the level of product noise. This has been common practice in noise control industry. However, it is very straightforward common sense that we have consider human perception on noise. In this paper, we propose a noise control strategy which takes into account the subjective perception of product noise. We especially has concentrated on a refrigerator noise. The proposed method is composed of 3 steps. Firstly, the actual refrigerator noise signal is measured. Then, to make the sample noise set for subjective assessment the noise signal is edited in 1／3 octave bands. Finally, we establish a strategy of refrigerator noise control by using the results from subjective assessment of these noise signals

3DTV is expected to be a promising next-generation broadcasting service. On the other hand, the visual discomfort/fatigue problems caused by viewing 3D videos have become an important issue. This paper proposes a perceptual quality assessment metric for a stereoscopic video (SV-PQAM). To model the SV-PQAM, this paper presents the following features: temporal variance, disparity variation in intra-frames, disparity variation in inter-frames and disparity distribution of frame boundary areas, which affect the human perception of depth and visual discomfort for stereoscopic views. The four features were combined into the SV-PQAM, which then becomes a no-reference stereoscopic video quality perception model, as an objective quality assessment metric. The proposed SV-PQAM does not require a depth map but instead uses the disparity information by a simple estimation. The model parameters were estimated based on linear regression from the mean score opinion values obtained from the subjective perception quality assessments. The experimental results showed that the proposed SV-PQAM exhibits high consistency with subjective perception quality assessment results in terms of the Pearson correlation coefficient value of 0.808, and the prediction performance exhibited good consistency with a zero outlier ratio value.

The third-person perception phenomenon can consistently be found in opinion poll news, but it remains unknown what determines the degree of the third-person perception (TPP) about specific election poll news. We investigated how respondents' preferred candidate's status in the poll affects the perceived impact of polling news on both themselves (PMI1) and on others (PMI3) as well as TPP (PMI3 - PMI1). We also examined the effect of subjective political knowledge and the perceived level of political knowledge of others on TPP. An online experiment was conducted in the context of a gubernatorial election in South Korea, in which the leading candidate in the poll and the question order (self-question first vs. other-question first) were manipulated. The results indicated that PMI1 and PMI3 were greater when the respondent's preferred candidate was leading in the poll. TPP did not differ depending on subjective knowledge, but it was greater when the others were non-experts (vs. experts). Lastly, question order was found to be a method factor that affected both PMI1 and PMI3. The theoretical and practical implications of these findings are discussed.

Purpose: This study aims to categorize the subjective perception of suicide of young social workers in their 20s and 30s, and to explore the factors constituting each type, and used the Q methodology. Research design, Research method: As a research method, the Q population was derived through in-depth interviews and literature research, and the final 23 Q statements were confirmed. Next, 30 social workers in their 20s and 30s were classified by normal distribution on a 7-point scale as a P sample. The collected data were analyzed using the QUANL-PC program. Result: As a result of the analysis, four types were extracted, and there were no affirmative statements commonly cited in all types, and the opposite statement is 'if someone wants to commit suicide, it is the person's job and should not interfere'. Types 4 named suicide as 'unacceptable social problem', 'signal of a request for help, relief of severe pain, and 'impulsive mistake', respectively. Conclusion: Based on this result, the elements constituting the perception of each type were analyzed, and the need for access strategies for each type of suicide prevention education and campaign, and follow-up research were suggested.

The relationship of stress and psychopathology with subjective or objective tinnitus intensity was investigated in 43 patients with tinnitus. Global assessment of recent stress scale, Beck depression inventory and symptom checklist-90-revision were used to measure stress perception and psychopathology. Subjective tinnitus intensity was assessed by subjective tinnitus severity inventory, whereas objective tinnitus intensity was assessed by tinnitogram. Scores of perceived stress related to interpersonal relationship and sickness or min had significantly positive correlation with subjective tinnitus intensity. In psychopathology, scores of somatization, interpersonal sensitivity, depression, anxiety, phobia, paranoid ideation, psychoticism had significantly positive correlation with subjective tinnitus intensity. However, stress perception and psychopathology did not significantly correlate with objective tinnitus intensity. These findings suggest that tinnitus may be associated with stress perception and multiple psychopathology including anxiety and depression. Thus, it is emphasized that Psychosocial intervention as well as effective consultation-liasion activity is needed for evaluation and treatment of patients with tinnitus.

In Korea, 'spoon class discourse' has attracted public attention in the press and among young people, which reflects that mass awareness that the class status structure is clearly rooted in the society becomes widespread. Although income distribution has been improved since late 2000s, it is interesting that Korean people's subjective perception concerning class mobility and social justice has been worsemed. By using the survey data on people's perception of opportunity inequality, this study finds that Korean people have by and large negative subjective awareness regarding socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts, and that the degree of the negative perception is greater in accordance with the people's subjective identification. The regression analysis reveals that the social status of respondents and their parents(-), experience of discrimination(+), age(-), and high education of college and above (+) have consistent effect over socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts with statistical significance. More concretely, as people have lower subjective status identification at the time of parent generation and their own generation, as they have the experience of discriminatory misconduct, and as they are young and highly educated, they have negative or pessimistic perception regarding opportuinity inequality. In addition, it is revealed that the unemployed and non-regular workers have significantly negative perception on socio-economic opportunity inequality, magnitude of opportunity inequality, while negative perception on the magnitude of opportunity inequality and achievement by efforts is noticeable among high and middle income households.

The purpose of this study was to find out the factors influencing asthma, allergic rhinitis, and atopic dermatitis among Korean adolescents. Data of 72,060 adolescents aged 12 to 18 years were derived from the 10th Korean youth's risk web-based study, which was conducted in 2014. Multiple logistic regression analysis revealed that factors influencing asthma was sex, age, BMI, subjective socioeconomic status, smoking, and subjective perception of stress. Factors influencing allergic rhinitis was age, place of residence, subjective socioeconomic status, drinking, and subjective perception of stress. Factors influencing atopic dermatitis was sex, age, subjective socioeconomic status, drinking, and subjective perception of stress. In conclusion, regulatory policy of lifestyle, such as smoking and drinking adversely affect allergy related disease in adolescents strengthening comprehensive prevention education and stress management are probably the two need to be implemented at national side.
