This paper tried to investigate the moderating effect of chemyon sensitivity and usage situation in the relationship between self-presentation and brand preference. Data were collected from students of universities located in Chungnam. The analysis results can be summarized as follows. First of all, the effect of self-presentation on symbolic brand preference was not significant in both public and private use situations. On the other hand, the effect of self-presentation on functional brand preference was found to be significant in both situations. Second, the main effect of chemyon sensitivity was significant only when it had a negative effect on functional brand preference in public situations, but was not significant in other cases. Third, looking at the interaction effect of self-presentation and chemyon sensitivity, the brand preference did not show significant changes in those with relatively low chemyon sensitivity, regardless of the level of self-presentation, whether in public or private situations. This study is meaningful in that it reveals that chemyon sensitivity affects brand preference through interaction with self-presentation, whether the consumption situation is public or private.

Today, apartment houses account for a very high proportion of the types of residence. This study analyzed the difference between the bidding construction cost using the long-term repair allowance and using the general repair cost, and analyzed the difference of factors affecting the amount of use of these two items. For this purpose, related data on apartment housing complexes located in seven representative districts of Busan from 2017 to 2021 were collected and analyzed from the apartment housing management information system. As a result of statistical analysis, the type of bidding variable had the greatest negative(-) effect on the bidding construction cost, and the next factor that affected was different between the amount of long-term repair allowance used and general repair cost used. In addition, there was a difference in statistical significance in the type of bidding by construction year for the number of bidding works between the case of using the long-term repair allowance and the case of using the general repair cost. The results of this analysis will help to find ways to reduce bidding construction costs. However, it is expected to find additional meaning by including more detailed variables such as technical ability.

This study was attempted to investigate the effects of psychological safety and physical self-concept on ego-resilience of nursing students. This data collected from September to November 2021 through a structured questionnaire from 166 nursing students at M University in Jeolla Southern Province. For data processing, descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation analysis, and multiple regression analysis were performed using the SPSS 23.0 program. As a result of this study, there were significant positive correlations in the self-resilience of nursing students with psychological stability and physical self-concept(r=.480, p<.001, r=.426, p<.001). The factors affecting the ego-resilience of nursing students were psychological safety(β=0.352, p<.001) and physical self-concept (β=0.236, p<.001), and the explanatory power was 26%. As a result of this study, it is necessary to increase psychological safety and physical self-concept in order to increase the ego-resilience of nursing students. It is necessary to develop and apply guide programs that enhances psychological stability for nursing students, and to provide education and facilities so that they can have a healthy body and mind, not only academics.

This study was aimed at exploring the parenting experience of fathers in single parent families as well as comprehensively determining their parenting experiences and the various parenting resources and support systems that have emerged in the process. The subjects were five divorced fathers who had not remarried and had been raising their children on their own. This qualitative case study involved data collect through in-depth interviews. The inter-case analyses derived two topics, five categories, and 17 concepts related to the issues of interest. The results indicated, that, first, there was "psychological confusion in the early stages of parenting" because of the sudden onset of this responsibility after divorce. Second, in the parenting experience, the fathers felt that "family survival was at stake". Third the support systems that the fathers had in raising single parent families were "social resources" made available through workplaces, acquaintances, institutions, and the government. Such systems also took the form of "family resources" including brothers and parents. An "internal resource" was the presence of children along with psychological sources of support, such as responsibility and the satisfaction experienced by the fathers through parenting. This study, uncovered the reality, resources, and support systems of fathers in single families. It is meaningful in that it will serve as a basis for supporting practical measures and educational interventions for fathers in single-parent households.

The purpose of this study is to quantitatively and qualitatively analyze the science journals written by pre-service elementary school teachers, and to categorize the view on the nature of science and the process of their change. For this purpose, 112 science journals written by 13 pre-service elementary school teachers were analyzed. The frequency of each area was analyzed using the research framework of the four areas of the nature of science, and the pattern of change in perspective on the nature of science was inductively derived and classified using the VNOS-C test analysis framework. As a result, The nature of scientific thinking, nature of scientific knowledge, nature of STS, and nature of scientific inquiry were described in relatively similar proportions, but among them, The nature of scientific thinking appeared in the largest percentage, and the nature of scientific inquiry was described in the smallest percentage. The variability of scientific knowledge, the importance of empirical evidence, and the positive and negative effects of science were especially intensively addressed. In addition, the changing aspects of pre-service elementary school teachers' perspectives on the nature of science could be categorized into 'naive view maintenance type', 'informed view maintenance type', 'regression type', 'development type', and 'mixed type'. The element of 'the empirical nature of scientific knowledge' showed various patterns of change depending on the students, and most of the students maintained a informed view on the tentativeness of scientific knowledge for several sessions.

This study investigated the relationship between older driver's safe driving behavior, driving mobility(amount of driving, assessment for driving-related physical ability, confidence for adaptation in driving situation, amount of social activity) and subjective well-being(life satisfaction, positive/negative affect). The data of these variables were collected by questionnaire method based on face-to-face interview. The results can be summarized as followings. First, the older driver who reported higher scores in the self-report safe driving behavior questionnaire tended to show higher level of subjective well-being and driving-based mobility. Second, all the sub-factors in the driving-based mobility questionnaire were positively related to life satisfaction, positive affect but negatively related to negative affect except amount of driving. Finally, it was found that both confidence for adaptation in driving situation and amount of social activity positively mediated the relationship between self-report safe driving behavior and life satisfaction and positive affect, but confidence for adaptation in driving situation negatively mediated the relationship between self-report safe driving behavior and negative affect, Implication and suggestion were discussed.

소하천의 유속계측을 위해 가장 많이 사용되고 있는 표면영상유속계는 표면유속을 계측하는데, 계측된 표면유속을 이용하여 유량을 산정하기 위해서는 수심 평균유속으로 변환할 필요가 있다. 이때 평균-표면유속 환산계수가 주로 사용되는데, 적정 환산계수를 산정하기 위해서는 수심별로 유속을 직접 계측하고 계측된 유속분포를 이용하여 평균-표면유속 환산계수를 산정하는 방법을 사용한다. 그러나 소하천은 홍수시 유속이 매우 빨라 물속에 직접 들어가는 것이 어렵고 장비를 이용하여 간접적인 방법으로 계측을 한다고 하더라도 소류사와 유송잡물 등으로 계측기가 파손되어 직접 계측에는 한계가 있다. 또한 직선구간 확보나 식생 등으로 부자를 이용한 계측도 어려워 계측 결과를 이용하여 환산계수를 산정하는 방법은 한계가 있다. 이런 이유로 대부분은 USGS가 제시한 0.85 ~ 0.95 범위 값 중에서 현장 여건을 고려하여 최적값을 결정·사용하고 있다. 본 연구에서는 홍수시 수심-유속분포를 직접 계측하기 어려운 소하천에서 표면영상유속계를 이용하여 계측한 수심별 표면유속분포를 이용하여 평균-표면유속 환산계수를 산정하는 방법을 개발하였다. 개발한 방법을 정량적으로 평가하기 위하여 건설기술연구원의 안동 하천실험시설에서 표면영상유속계로 수심상승에 따른 횡방향 유속분포를 계측하고 수위가 완전히 상승한 이후의 안정된 흐름 조건에서 플로우트래커를 이용하여 수심별 횡방향 유속분포를 계측하여 두 계측결과를 1:1로 비교하였다. 비교 결과 표면영상유속계로 계측한 수심별 표면유속분포와 플로우트래커로 계측한 수심-유속분포 결과는 유사한 분포를 보이는 것으로 나타나 표면영상유속계로 계측한 수심별 표면유속분포를 이용하여 평균-표면유속 환산계수를 산정하는 것이 가능하다는 결론을 도출하였다. 본 연구에서는 개발한 평균-표면유속 환산계수 산정방법의 적용성을 검토하기 위하여 표면영상유속계가 설치된 5개 시범소하천에서 7년(2016~2022)간 계측한 수심별 표면유속 자료를 수집하고 이 결과를 이용하여 평균-표면유속 환산계수를 산정하였다. 산정결과 대부분 USGS가 제시한 범위내의 값을 보이는 것으로 나타나 향후 본 연구의 개발 방법을 평균-표면유속 환산계수 산정에 활용할 수 있을 것으로 판단된다. 본 연구에서는 개발한 환산계수 산정방법은 향후 보다 많은 수리실험과 현장실험 등으로 정밀검증을 수행한다면 홍수시 수심-유속분포를 직접 계측하기 어려운 소하천에서 간편하면서도 적용성이 큰 신기술 확보가 가능할 것으로 기대된다.

The aims of this study were 1) to compare irrational gambling beliefs of gamblers and non-gamblers, 2) to investigate the role of cognitive error on winning probability thinking error, and 3) to examine the relationship between attributional bias and gambling behavior. A total of 248 subjects were recruited for this study. All subjects were classified into non-gamblers, social gamblers and pathological gamblers, and administered self-report questionnaires to measure irrational gambling beliefs, the probability inference error, the attriburional style, and the attributional bias. A pathological gambler group scored highest on irrational gambling beliefs, especially the overestimation of self-ability factor, and a social gambler group and a non-gambler group follow. All three groups scored higher on the magnification of gambling skills than the mean (4.0) of the scale. Pathological gamblers and social gamblers scored higher on the probability thinking error than non-gamblers. Pathological gamblers displayed higher external attribution, lower internal attribution in their daily life events and higher internal attribution in failure situation than social gamblers and non-gamblers. The results indicate that cognitive errors would be a factor that differentiates pathological gamblers from social gamblers and non-gamblers. In predicting gambling behaviors, overestimation of self-ability of irrational gambling beliefs, internal attribution in failure situation, external attribution in daily live event, and probability thinking error were identified as significant factors. It is concluded that a public education about common cognitive bias featured in gamblers might be important in prevention of pathological gambling behaviors.

This study intends to identify the effect of the simulation-based adult nursing education on resilience, clinical competence, and role transition of nursing students. Similar experimental study of a single group pretest-posttest design was used to investigate the effects of the program. The study was conducted from March to June, 2017 on senior nursing students at the university in M city who take an 'Integrated nursing practice I' class for the semester. Data were collected through self-report questionnaires and data of 52 participants were analyzed. The data were analyzed by frequencies, paired t-test and pearson's correlation coefficient using SPSS 21.0 program. As a result, the effectiveness of the simulation-based adult nursing education on resilience, clinical competence, and role transition were found. The result of this study showed that the improvement after simulation education was significant in resilience(t=-2.51, p=.016), clinical competence(t=-4.18, p<.001), and role transition(t=-2.89, p=.006). Resilience was found to be positively correlated with clinical competence(r=.464, p<.001) and role transition(r=.473, p<.001). These findings imply the value of simulation education to enhance the resilience, clinical competence, and role transition of nursing students. In the future, more studies should be conducted in the same group with control group to validate the effectiveness of variables.
