The tonal music organizes the tones based on the hierarchy of the relative importance of musical tones. So listeners who are familiar with a certain musical style internalize the tonal schema of that music in mind, though they have no formal training about these organizing principles. This research examined how the western music experts who are not familiar with classical Korean music interpret classical Korean music. In the other researches about musical styles outside the western music, the superficial informations such as the distribution and the duration of tones in the experimental stimulus might be used as cues to extract the tonal schema of that music. In this study, these superficial informations were controlled in order to reduce this possibility. The results showed that the western music experts might interpret classical Korean music with the tonal schema of western music. but, thought the western music experts perceived classical Korean music on the base of the western musical framework and so their interpretation was not match with the tonal schema of classical Korean music. their interpretation was more similar to classical Korean tonal schema than the non-musicians interpretation of classical Korean music. These results suggested that the extensive experiences in a specific musical style can facilitate the listeners proper apprehension of the other musical styles.

This study is a descriptive correlation that attempts to determine the mediating effect of self-efficacy on the relationship between university life stress and smartphone overuse. A total of 201 university students attending universities within Jeonbuk were evaluated using self-reported questionnaires from April 10 to May 10, 2017. The demographic characteristics, university life stress, self-efficacy, and smartphone overuse were analyzed by descriptive statistical analysis. The difference in smartphone overuse by demographic characteristics was analyzed by t-tests and ANOVA with Scheffe's post hoc test, and the correlation between variables was evaluated by Pearson's correlation coefficient. The mediating effect of self-efficacy was the 3-step multiple regression statistics of Baron and Kenny, and the statistical significance of the mediating effect was analyzed by the Sobel test. Self-efficacy had a partial mediating effect in the relationship between university life stress and smartphone overuse. In addition, the risk of smartphone overuse increased among university freshmen, with many using smartphones for more than 4 or 6 hours per day. The result of this study are expected to be useful as basic data for the development of a program to prevent excessive smartphone use by university students.

In this study, memory for emotional words was compared between extraverts and introverts, employing signal detection analysis to distinguish differences in discriminative memory and response bias. Subjects were presented with a study list of emotional words in an encoding session, followed by a recognition session. Effects of task difficulty were examined by varying the nature of the encoding task and the intervals between study and test. For an easy task, with a retention interval of 5 minutes (Study I), introverts exhibited better memory (i.e., higher d') than extraverts, particularly for low-frequency words, and response biases did not differ between these two groups. For a difficult task, with a one-month retention period (Study II), performance was poor overall, and only high-frequency words were remembered; also extraverts adopted a more liberal criterion for 'old' responses (i.e., more hits and more false alarms) for positive emotional-valence words. These results suggest that as task difficulty drives down performance, effects of internal control processes become more apparent, revealing differences in response biases for positive words between extraverts and introverts. These results show that extraversion can distort memory performance for words, depending on their emotional valence.

Objectives : This study was done to develop Korean form of Reynolds' SIQ-JR(Suicidal Ideational Questionnaire-Junior). Through this study we evaluated reliability and validity of Korean form SIQ-JR. Methods : Subjects were 1,160 middle and high school students and 114 adolescent psychiatric patients. SIQ-JR and 8 self-reporting scales highly related with suicidal ideation and suicide behaviors were applied to them. Results : In reliability aspect of Korean form of SIQ-JR, internal consistency, test-retest reliability and item-total correlation were statistically significant results. In factor analysis, concerning about other person was extracted as a indepenedent factor. This results reflect our cultural characteristics. There were statistical differences of SIQ-JR scores in groups by sex and age. Clinical group showed significantly(P<0.01) higher scores than general population. Among the 8 suicidal relating scales, depression(r=0.42), aggression(r=0.36), trait anxiety(r=0.35), and anger-in(r=0.31) were highly related with suicidal ideation but impulsivity and hopelessness were not significantly related with suicidal ideation. Conclusion : Korean form of SIQ-JR was useful instrument in reliability and validity. We hope that this instrument widely used in school mental health, community psychiatry and clinical setting for screening tool.

This study was undertaken to grasp health-promoting behavior of the elderly and to identify variables related to them in order to facilitate nursing intervention for health promotion of this population. The subjects for this study were 291 old persons obtained by cluster sampling from twenty general social welfare centers located in Tague. Data were collected by self-reported questionnaires from August 13 to September 13, 1996. Questionnaires were developed based on Sherer and others' Self-Efficacy scale, Rosenberg's Self-Esteem scale, Wallston and other's Multidimensional Health Locus of Control scale, Northern illinois University's Helath Self Rating Scale, Walker and others' Health Promotion Lifestyles Profile. Analysis of the data was done by use of descriptive statistics, stepwise multiple regression, Pearson Correlation Coefficient, MANOVA, t-test, and ANOVA. The results were summarized as follows : 1. For the practice of health-promoting behavior, the mean score was 2.89 and range was 3.59 to 2.09. The factor of the highest mean score was regular diet(M=3.42) and factor of the lowest mean score as stress management(M=2.27). 2. The combination of self-efficacy, internal health locus of control, family number, and average monthly pocket money explained 30.0% of the variance of health-promoting behavior. 3. With regard to the relationship between health-promoting behavior and cognitive perceptual factor, self-efficacy correlated positively with health-promoting behavior(r=.4951, P=.0001), self-esteem correlated positively(r=.3263, P=.0001), internal health locus of control correlated positively(r=.3244, P=.0001), perceived health status correlated positively(r=.1355, P=.0274). 4. According to age(F=2.50, P=.0431), sex(t=2.14, P=.0332), marital status(F=7.85, P=.0005), education(F=5.44, P=.0003), family number(F=11.18, P=.0001), people living together(F=7.21, P=.0009), previous occupation(F=5.83, P=.0001), average monthly pocket money(F=7.27, P=.0001), there were differences of health-promoting behavior. The above findings show that health-promoting behavior are related to demographic characteristics, four cognitive perceptual factors(self-efficacy, self-esteem, internal health locus of control, perceived health status). On the basis of the above findings the following recommendations are made ; 1. Nursing interventions enhancing exercise or activity, accountability for health, stress management of the elderly must be provided. 2. Nursing strategies enhancing self-efficacy which is most significant effect on health-promoting behavior must be developed.

The main purpose of this study is to provide the necessary information for educational intervention by discovering the components and factors related to the adaptation experience of male students in the department of nursing. The participants were seven male nursing students. Data were collected from in-depth interviews, and the results were analyzed by the Giorgi's phenomenological analysis method. The main components of adaptation experience of participants were summarized into four categories: 'hopes and expectations for the future careers,' 'conflicts and wandering under realistic issues,' 'compromise and emotion management,' and 'efforts for self-growth.' Causative, accelerative, and recursive characteristics were shown among these components. The adaptation process was structured in the temporal context. The results suggest that for amicable adaptation, internal controls, such as 'improving willpower,' 'inspiring solid career awareness,' and 'selecting adaptation strategy' were all critical. Moreover, the support of families, relatives, college seniors, and department professors were revealed as the factors that help in the adaptation experiences. Based on the results, further studies are required to identify the dropout rates by maladaptation of male nursing students, and analyze possible factors that contribute to dropout and maladaptation. In addition, it is necessary to construct various coping methods and practical support systems, as well as to develop appropriate educational programs.

KOSDAQ market reorganized their division system from two types to four types of division departments such as blue chip, venture, medium, and technology development departments in 2011. However, under the current new division system, financially unhealthy firms attempting to take advantage of the classifying opportunity of blue chip department are likely to engage in pernicious earnings management. The objective of this study is to investigate the earnings management behavior surrounding the time of KOSDAQ firms entering the blue chip department via new division system. More specifically, we test whether the firms classified blue chip department tend to engage in upward earnings management using accruals and real activities before and after they achieve blue chip status. In this study, we analyzed 111 firms classified blue chip department in 2011 according to new division system in KOSDAQ market. Major test results indicate that firms entering the blue chip department according to current KOSDAQ division system in general, tend to inflate reported earnings by means both of accruals and real activities right before the entering year. This result suggests that the firms classified blue chip department engage in opportunistic earnings management with a view to uplifting their market values. Our study is expected to provide clues useful for searching policy directions which intend to ameliorate adverse side effects of the current KOSDAQ division system. In sum, the regulatory authorities and enforcement bodies need to exercise caution in deliberating more stringent review procedures so that financially healthy and promising candidates are properly segregated from their poor and risky counterparts, thus enhancing the beneficial effects, while mitigating adverse side effects of the system.

This article presents a historical account of media role in the transition and consolidation period of democracy. Despite the assumption that media plays a important role in the construction of democracy, it is less clear how the media can affect the process of political change itself. This article seeks to answer some of these question, based on the Mill's macro-social comparative 'method of difference' of Korea and Spain. It is widely agreed that both states achieve democracy through transaction from above(pacts). Media role, however, differs significantly in accordance with authoritarian legacies and civic representativeness of the pacts. Whereas Korean dailies is deepening given market oligopoly and prior practices after democratization, Spain dailies market entirely changed in both structural and spiritual respects. As a result, Korean dailies substantially lacks in civic representativeness as before, contrary to Spain. Spain television settled a sort of the external pluralism. Korean television is pursuing the BBC type of internal pluralism. In Korea, television is more commercial than Spain. Consequently, Spain media serve the consolidation of democracy more than Korea on the whole.

Even though civilization is developing at a fast rate, human beings and their living environments do not look happy. Given that the civilization comes from the human mind, which is changing in interaction with human body, society, and nature, it is hard to think that the human mind is changing in the desirable direction. This paper described a whole changing paradigm of the human mind and its causes through the cognitive mechanism in the brain from which all the diverse minds are formed. According to the cognitive mechanism, the human mind can change from the first free and peaceful mind through the middle mind to the last obsessive and anguish mind in accordance with the change of one of the factors in the origin of the human mind. Today's unfavorable changes in human beings, society, and the natural environment including the excessive development of civilization are the results of the undesirable changes of the human mind. This paper specified the respective characteristics of the first, middle, and the last mind and discussed where individuals' minds are and where they are going. Lastly, this paper suggested the specific ways to return to the first original mind based on the cognitive mechanism.
