This study examined the potential teaching strategies of prospective elementary teachers and their perceptions of the procedural/conceptual nature of examples. Fifty-four prospective teachers participated in this study, engaging in two-phase tasks. Analysis of data indicated that: (a) Overall, the participants' perceptions were geared toward putting emphasis on conceptual understanding rather than procedural understanding; but (b) Generally, procedure-oriented strategies were more frequently incorporated in participants' potential teaching plans. This implied that participants' preconceived ideas regarding math examples were not always reliable indicators of their potential teaching strategies. Implications and suggestions for mathematics teacher preparation are discussed.

The purpose of this study was to search for empirical evidence between internalized shame with self-control, aggression, and addiction potential. Also examine the differences between clinical group and normal group. The data was collected from 100 AA participants and 380 Non-AA participants. For measuring each variable, internalizes shame scale(ISS), self-control rating scale(SCRS), Buss-Durkee Hostility inventory(BDH), addiction potential scale(APS) were used. The survey result was analyzed with Pearson Correlation, Partial correlation and t-test. The results shows: Frist, the internalized shame and the aggression, the addiction potential shows a positive correlation but the self-control shows negative correlation. Second, after control self-control, internalized shame positively correlate to addiction potential and aggression. Third, clinical group recorded a higher level in internalized shame, aggression and addiction potential than normal group; a lower level in self-control. Based on the finding, the implications of understandings, the interventions, the limitations of this study, and the suggestions were discussed.

The domestic handbag market has potential of growth - the key to protect this growing market from foreign makers is good design and better quality. 68 people(29.6%)out of 230 survey participants report 'to own 5 handbags', and the most popular(frequently reported) maker is 'MCM', owned by 49 participants(21.3%). 150 participants(65.2%) out of 230 total participants purchase at least one handbag a year, and 136 participants(59.7%) out of 230 spend between 110,000 and 200,000 Korean wons. 52 participants(22.6%) out of 230 own high-end handbags worth 500,000 Korean won or more. Among the high-end handbags, Louis Vuitton is the most popular, owned by 19 participants. The overall criteria in handbag purchase are 'color', 'price', 'pattern and logo', 'reputation', 'material', 'storage room', and 'size', in the descending order of importance. The most frequently desired benefit in handbag purchase is 'to stay through trends' i.e. not to go out of fashion too easily. The favored designs are made with rectangle shape with large width, soft material, attached handles, leather material, modern style. The most frequently cited reason to purchase a high-end brand item is 'because of high quality'.

The area of discourse analysis has long neglected the value of images as a semiotic resource in communication. This paper suggests that like language, images are rich in meaning potential and are governed by visual grammar structures which can be utilized to decode the meanings of images. Employing a theoretical framework in visual communication, two digital images are examined for their representational and interactive dimensions and the dimensions' relation to the magazine advertisement genre. The results show that the framework identified narrative and conceptual processes, relations between participants and viewers, and symbolic attributes of the images, which all contribute to the sociological interpretations of the images. The identities and relationships between viewers and participants suggested in the images signify desirable qualities that may be associated to the product of the advertiser. The findings support the theory of visual grammar and highlight the potential of images to convey multi-layered meanings.

Physical activity (PA) professionals and participants recognize enhanced quality of life (QoL) as a benefit of and motivator for PA. However, QoL measures are often problematic and rarely consider the participants' perspective. This paper focuses on recent findings from a larger project on the role of QoL in PA and health promotion. More specifically, we focus on the views of participants and potential participants to better understand the relationship of PA and QoL. In earlier stages of the project we began with a conceptual model of QoL and developed a survey. We now focus on participants' views and ask two questions: 1) what is QoL? and 2) how does PA relate to QoL? We first asked those questions of a large sample of university students and community participants as open-ended survey items, and then asked focus groups of community participants. Overall, participants' responses reflected the multidimensional, integrative QoL model, but the responses and patterns provided information that may not be picked up with typical survey measures. Findings suggest that PA contributes to multiple aspects of QoL, that social and emotional benefits are primary motivators and outcomes for participants, and that the meaning of QoL and PA benefits is subjective and contextualized, varying across individuals and settings. Programs that directly target and highlight the multiple dimensions and integrative QoL, while considering the individual participants and contexts, may enhance both PA motivation and participants' health and QoL.

Purpose: This study was designed to describe the experiences of dementia prevention program for older adults in nursing homes. Methods: Four focus group interviews (FGI) after the program were conducted with 35 participants. All interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed by Colaizzi's phenomenological method. Results: Four themes emerged as a result of analysis. Participants without dementia reported "I don't have dementia yet." This statement probably reflects ignoring potential dementia. Motivation for participating the dementia prevention program were to reduce boredom, to enjoy exercising and communicating with others, and to follow group activities. Participants reported the positive effects of the program; (a) benefits from the repeating learned activities; (b) improvements of memory and emotional stability. A few participants reported their inability to follow the program due to physical and environmental limits. However, other participants reported their efforts to overcome physical limits and perform the activities regardless their limits. People who performed the activities with physical limits reported that their self-satisfaction was increased. Conclusion: Results of this study showed that participants without dementia were able to actively participate in dementia prevention programs and showed memory, emotional and behavioral improvements. Therefore, these findings can be used for developing customized dementia prevention programs in nursing homes.

The purpose of this paper is to investigate the planning characteristics of certain cases of elderly welfare housing (hitherto EWH), and analyze any problems by comparing this against the actual needs of potential residents. To this end, 38 distinct housing plans from twelve EWH built after 2005 were examined, and a survey on housing needs was taken by 198 people between 48 and 62 years of age. The results are as follows: Firstly, the most common size found among the 10 cases was 42-66 $m^2$, however larger sizes are becoming more frequent. The most popular response on the survey was one favoring smaller housing options. Secondly, the most common floor plan examined consisted of 1 bedroom + LDK and 2 bedroom + LDK. Likewise, the survey reflected that 1 or 2 bedroom housing was preferred. Thirdly, a floor plan composed of a smaller bedroom and LDK is commonly found in smaller floor plans of EWH. The survey reflected potential residents preferred this same style of floor plan, with a smaller bedroom and LDK set up. However, lower-income participants preferred a single, larger bedroom which also can serve as a living space, to go along with a kitchen/dining room (DK). Fourthly, 2 bedroom housing typically included a single bathroom, however the survey indicated that participants preferred a second bathroom to go along with a second bedroom. Consequently, the planning of elderly welfare housing is to a large extent meeting the demands of its potential residents, however house size and the planning of bathrooms have yet to meet these demands, especially with potential lower-income residents when it comes to housing size and space composition.

Objective : There have been limited scientific studies differentiating those who attempt suicide from those who think about suicide but do not attempt suicide. Altered event-related potential (ERP) performance, such as GoNogo ERP has been regarded as the neurocognitive processes associated with behavioral inhibition and poor impulse control. The purpose of this study was to investigate the association between Nogo ERP and suicide attempt. Methods : A total of 63 participants (33 participants with suicide ideation and 30 with suicide attempt) were recruited, and performed GoNogo tasks during the electroencephalogram measurement. Depression, anxiety, emotional regulation and impulsivity were evaluated by self-rating scales. The clinical measures and Nogo P3 component were compared between the groups. The correlational analyse was conducted to evaluate the relationship between the clinical characteristics and the Nogo P3 component. Results : Participants with suicide attempt significantly decreased the Nogo P3 amplitudes at the frontal-central electrode than participants with suicide ideation (p=0.004, FDR adjusted p=0.032). In the correlation analysis, the Nogo P3 amplitude at frontal-central electrode was correlated with the total score of the Barrett impulsivity scale (r=-0.383, p=0.002), attentional impulsivity (r=-0.365, p=0.003) and motor impulsivity (r=-0.389, p=0.002) subscales of the Barrett impulsivity scale. Conclusion : These findings suggest that the decreased Nogo P3 amplitude may be one of the candidates of biological marker for poor impulse control in those who attempt suicide.

Background: Organizational ostracism is defined as a violation of norms that we are suggested to acknowledge at the workplace. It results in the exclusion of one person or multiple persons, and causes damage to our innate need to belong. This kind of behaviorism can be engaged through a hierarchical or nonhierarchical relationship. Three elements interact in the framework of organizational ostracism: the actor, the target, and the institution. Our aim was to describe the different factors interacting with every element in order to produce recommendations targeting to prevent the occurrence of such behaviorism in an institution and to help targets of such a violence in order to handle this situation and go forward. As psychological impact of ostracism has frequently been studied in the literature, we focused on its impact on professional tasks. Methods: We performed a questionnaire-based study about organizational ostracism. This questionnaire was established through an online platform (https://www.sondageonline.com) and made available through the following link: https://goo.gl/forms/KrkVXe3bMEc79cau2. A keyword was sent to all participants. We created a 23-interrogation questionnaire with open and short questions. Nonwritten consent was obtained from all participants. Results: The actor of ostracism engaged in ostracism, in most of the cases, with other persons without a real purpose. The actor of ostracism had an antecedent of problematic relationship at work in 82.9% of the cases. Of the participants, 58.5% were of the view that ostracism aimed to cause hurt and isolate them. Professional isolation was observed in 58.5% of the cases; 51.2% of the participants tried to improve their work potential and explained their reaction by an intrinsic motivation. The organization atmosphere was judged to be bad in most of the cases. Conclusion: Our study showed that ostracism was mainly observed in public practice.

BACKGROUND/OBJECTIVES: Asthma and allergic rhinitis (AR) are closely related and considered as allergic respiratory diseases (ARD), and their prevalence has recently increased. Data on the association of dietary antioxidant vitamin intake with asthma and AR in adults are limited. The present study aimed to investigate the associations of vitamin A and C intake with asthma, AR, and all cases of both diseases in young adults who participated in a cross-sectional national survey, with the use of high-sensitivity C-reactive protein (hs-CRP) level as an effect modifier. SUBJECTS/METHODS: This study included 6,293 male and female adults aged 20-49 years from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2016 and 2018. The questionnaire-based reports on asthma and AR diagnosis were used to determine outcome variables. Further, 24-h recall data on dietary vitamin A and C, carotene, and retinol intake were acquired. Logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence interval (CI). RESULTS: Dietary vitamin C intake was inversely associated with asthma prevalence among participants with hs-CRP levels (≥ 1 mg/L); the OR of asthma prevalence was 0.27 (95% CI, 0.08-0.84) for participants with vitamin C consumption ≥ 75 mg/day compared with those consuming < 20 mg/day. Similar association analyses limiting to non-users of dietary supplements were performed to rule out the potential effects of supplement intake on the outcomes; results showed a stronger association. However, the association between vitamin C and asthma was not significant in participants with hs-CRP levels < 1 mg/L; the OR of asthma was 1.44 (95% CI, 0.66-3.16) for participants with vitamin C consumption ≥ 75 mg/day compared with those consuming < 20 mg/day. Vitamin C intake was not associated with AR. Moreover, there was no association between vitamin A intake and neither asthma nor AR. CONCLUSIONS: These findings suggest that higher vitamin C intake may play a potential role in reducing asthma prevalence. Nevertheless, further studies should be conducted to evaluate whether this association is causal.
