The purpose of this study was to investigate the differences in social anxiety and stress coping style by the college students' levels of self-efficacy. The convenience sample consisted of 400 college students in six universities. The data were collected from May to June in 2013 using the following instruments: the Self-Efficacy Scale, the Interaction Anxiousness Scale and the Ways of Coping Questionnaire. Descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient were used to analyze the data using SPSS 21.0. Self-efficacy was found to have negative relation with social anxiety and positive relation with active coping style while social anxiety was negatively related to active coping style and positively to passive coping style. There were differences in social anxiety and stress coping style in accordance with the level of self-efficacy. The higher group in self-efficacy used more active coping than the lower group. The support and intervention program to increase self-efficacy would be effective in decreasing social anxiety and increasing active coping style among college students.

This study aimed to investigate the convergence relationship between kinesiophobia and fear of falling in patients with stroke. A total of 113 patients with stroke participated in this study. Participants underwent inpatient rehabilitation and completed surveys with three different questionnaires including the fall efficacy scale (FES), translated Tampa Scale for Kinesiophobia 13 (TSK-13), and activity-specific balance confidence scale (ABC). TSK-13 and FES showed weak negative correlation (r=-0.226), and TSK-13 and ABC showed moderate negative correlation (r=-0.300). FES had a very strong positive relationship compared with ABC (r=0.838). Faller showed significantly low FES and ABC scores compared with non-faller (p<0.05). These results present that patients with stroke had mild kinesiophobia, and kinesiophobia is related to fear of falling. It is necessary to evaluate kinesiophobia in stroke rehabilitation.

The purpose of this study was to investigate the effects of career maturity major satisfaction, self-control on university students' job stress. Data collection was conducted from November 2018 to February, 2019 in 236 students who understood the purpose of the study and agreed to participate in the study. The collected data were analyzed by frequency, mean, standard deviation, Pearson correlation analysis, and multiple regression. The lower the career maturity (β=-.258), job stress was the higher. Also, the lower major satisfaction (β=-.377), the higher the job stress, and the lower the self-control (β=-.275), the job stress was the higher. Through these results, education programs that link students from their childhood to college students are needed to improve their career maturity, satisfaction with majors and self-control(r=-.410, p<.001).

This paper investigate the volume-volatility and volume-return relationship in the Korean Treasury Bond futures market using daily price and volume data categorized by three trader type i.e. individual investor, institutional investor and foreign investor over the period of October 1999 through December 2005. Major results are summarized as follows: (i) The effect of volume on return was not different across the trader type. (ii) The effect of volume on volatility was not unidirectional across the type of investor. While unexpected sell of individual investor has positive effects on volatility, negative effects in the case of institutional investor. (iii) We cannot find the evidence of asymmetric response of volatility to shock in trading volume or net position. This result differs from that of Korean Stock Price Index 200 futures market which showed strong positive asymmetry. Finally, some limitations of this paper and direction for further research were suggested.

Antarctica isimportant area in order to understand climate change. In addition, this area is complex region where indicate warming and cooling trend according to previous studies. Therefore, it is necessary to understand the long-term variability of Antarctic energy budget. Net radiation, one of energy budget factor, is affected by albedo, and albedo cause negative radiative forcing. It is necessary to analyze a relationship between albedo and net radiation in order to analyze relationship between two factors in Antarctic climate changes and ice-albedo feedback. In thisstudy, we calculated net radiation using satellite data and performed an analysis of long-term variability of net radiation over Antarctica. In addition we analyzed correlation between albedo. As a results, net radiation indicates a negative value in land and positive value in ocean during study periods. As an annual changes, oceanic trend indicates an opposed to albedo. Time series pattern of net radiation is symmetrical with albedo. Correlation between the two factors indicate a negative correlation of -0.73 in the land and -0.32 in the ocean.

This study aims to analyze the factors that affect quality of life and sensory processing abilities in older adults. Participants were 121 older adults aged over 65. Quality of life was evaluated with Life satisfaction Index for the Elderly and sensory processing abilities were measured with Korean-AASP. Korean Activiy Card Sort was utilized to assess their activity level. Low positive correlations were found between quality of life and activity level in total score(p<.01), IADL(p<.05), leisure(p<.01), and social participation(p<.01). Correlation coefficients between quality of life and sensory processing abilities showed low negative correlations in low registration(p<.01), sensory sensitivity(p<.01), and sensation avoiding(p<.01), however, there were low positive correlations in sensation seeking(p<.05). The importance of sensory processing was highlighted from the findings of statistically significant correlations between quality of life and sensory processing abilities. This indicates that improvement of sensory processing abilities is critical in occupational therapy service for older adults. Furthermore, the findings of close relationship between activity levels and sensory processing abilities need to be reflected in senior welfare policy.

국어에서 wh-단어가 포함된 의문사 의문문과 부정사 의문문은 통사적으로 같은 구조를 가지지만 의미적으로는 중의 관계에 있다. 그러나 두 의문문은 문장으로 발화될 때 음성적으로 서로 다른 여러 가지 운율 특징의 차이를 보여줌으로써, 발화 차원에서는 더 이상 중의 관계를 유지하지 않는다. 본고에서는 이러한 중의성의 해소는 두 의문문의 초점이 달리 실현되기 때문이라고 본다. 기존의 연구에서는 두 가지 의문문의 억양 연구를 초점의 작용 범위와 문말 억양의 차이, 강세구 형성의 유형을 중심으로 고찰하였다 .그리고 의문사와 부정사의 의미는, 이에 후행하는 서술어와 형성하는 강세구 유형에서 우선적으로 그 의미가 구분될 수 있다고 보았다. 그러나, 본고에서는 국어의 wh-단어가 초점으로서 작용하는 운율적 돋들림을 좀더 다양한 환경에서 실험하였다. 그리고 의문사${\cdot}$부정사와 후행하는 언어단위의 강세구 형성(accentual phrasing) 유형, 의문사${\cdot}$부정사 의문문 전체 문장 억양의 실현 양상, wh-단어 자체의 음의 높낮이(pitch contour) 실현 유형, 문말 억양(boundary tone)에서 음의 높낮이를 대상으로 분석하였다.

We examine whether the observed negative relations between stock returns and inflation and between housing returns and inflation can be explained by the inflation illusion hypothesis. We identify the mispricing component in asset prices (i.e., stock prices and housing prices) based on present value models, linear and loglinear models, and we then investigate whether inflation can explain the mispricing component using the data from three countries (the U.S., the U.K., and Korea). When we take into account the potential asymmetric effect of positive and negative inflation on the mispricing components in asset prices, which is an important implication of the inflation illusion hypothesis, we find little evidence for the inflation illusion hypothesis in that both positive and negative inflation rates do not have a negative effect on the mispricing components. Instead, we find that behavioral factors such as consumer sentiments contribute to the mispricing of asset prices.
