The purposes of this study were to investigate the hairdo attitude and hairdo involvement importances and differences depending on age. For the experimental work, questionnaires for research are prepared and asked to people who are women living in Seoul and Kyoung-Ki Do. They are collected from September to October 2006. 406 questionnaires are used in the analysis. The collected data were 'analyzed by using SPSS 12.0 software with factor analysis, Cronbach's alpha, paired T-test, and T-test. The results of this study were as follows; To analyze differences in the hairdo attitude and the hair involvement depending on different age groups, two groups were identified: one group of women aged $20{\sim}35$, and the other group of those aged $45{\sim}60$. 1. When the hairdo attitude factors were prioritized, orientations toward 'constancy' and 'consciousness of others' were found to be most critical, followed by those toward 'leader's fashion conformity' and 'distinct individuality'. When the hairdo involvement factors were prioritized, 'interests and pleasure in hairdo' were found to be most important, followed by 'symbolic representation', 'risk awareness', 'coordination of hairdo', and 'fashionableness'. 2. When difference in the hairdo attitude was analyzed, a significant difference was shown in orientations toward 'leader's fashion conformity' and 'consciousness of others'. 3. As for the hairdo involvement of the groups, a significant difference was found only in 'coordination of hairdo', signalling that the younger women put more focus on the coordination.

Smart homes are the new generation of homes where pervasive computing is employed to make the lives of the residents more convenient. Human activity recognition (HAR) is a fundamental task in these environments. Since critical decisions will be made based on HAR results, accurate recognition of human activities with low uncertainty is of crucial importance. In this paper, a novel HAR method based on a difference of convex programming (DCP) problem is represented, which manages to handle uncertainty. For this purpose, given an input sensor data stream, a primary belief in each activity is calculated for the sensor events. Since the primary beliefs are calculated based on some abstractions, they naturally bear an amount of uncertainty. To mitigate the effect of the uncertainty, a DCP problem is defined and solved to yield secondary beliefs. In this procedure, the uncertainty stemming from a sensor event is alleviated by its neighboring sensor events in the input stream. The final activity inference is based on the secondary beliefs. The proposed method is evaluated using a well-known and publicly available dataset. It is compared to four HAR schemes, which are based on temporal probabilistic graphical models, and a convex optimization-based HAR procedure, as benchmarks. The proposed method outperforms the benchmarks, having an acceptable accuracy of 82.61%, and an average F-measure of 82.3%.

For a commonly used piezocone with a shoulder filter element, dilatory dissipation behavior, which shows an initial temporary increase in pore pressure, has been observed in overconsolidated cohesive soils. However, there is no appropriate way to estimate a consolidation parameter from a dilatory dissipation curve because currently available interpretation methods were developed based on the monotonic decrease of the excess pore pressure. In this study, the interpretation method for evaluation of coefficient of consolidation from a dilatory dissipation result of piezocone test was developed by performing the finite difference analysis on the dissipation after cone penetration. The distribution of the initial excess pore pressure induced by cone penetration, which is the core of the analysis, was estimated from the empirical modification of a solution proposed by cavity expansion theory and critical state concept. And the proposed interpretation method was applied to the field piezocone data and the results were compared to those obtained from laboratory tests. Its reliability was confirmed by the insignificant difference between the values of coefficient of consolidation from piezocone tests and laboratory consolidation tests.

The structure-soil-structure interaction (SSSI) effect in adjacent structures may affect the liquefaction-induced damage of shallow foundation structures. The existing studies only analysed the independent effects on the structural dynamic response but ignored the coupling effect of height difference and distance of adjacent structures (F) on liquefied foundations on the dynamic response. Therefore, this paper adopts finite element and finite difference coupled dynamic analysis method to discuss the effect of the F on the seismic response of shallow foundation structures. The results show that the effect of the short structure on the acceleration response of the tall structure can be neglected as F increases when the height difference reaches 2 times the height of the short structure. The beneficial effect of SSSI on short structures is weakened under strong seismic excitations, and the effect of the increase of F on the settlement ratio gradually decreases, which causes a larger rotation hazard. When the distance is smaller than the foundation width, the short structure will exceed the rotation critical value and cause structural damage. When the distance is larger than the foundation width, the rotation angle is within the safe range (0.02 rad).

The purpose of this essay explores a critical review of the Korean critical communication studies focused on the problematic of cultural studies and political economy in 2000s. The findings are as follows; The 'consumer turn' or 'audience turn' in new revisionism modelling John Fiske's cultural studies has been interpreted not to complement but to substitute the necessary criticism of the post-authoritarian media establishment of Korea at that time, arising identity crisis of Korean cultural studies as one of the critical camp. On other side, however, some political economy studies close to the unilinear theses of orthodox marxism has been appraised to neglect the complex process and structure of media and cultural production as well. While the press war between the market-dominant dailies and some progressive dailies has given rise to a whole debate as expected in consolidating period of Korean emerging democracy, the conjucturalism as modelled by Hall's 'authoritarian populism' failed to initiate a new theo tical practice in Korea. Finally, this review essay propose the some new research issues that would converge cultural studies and political economy, modernism and postmodernism; citizenship vs 'cultural citizenship'(valuing the private identity and gender) or Habermasian public sphere vs 'cultural public sphere', the culture of production, (modern)citizen/(postmodern)consumer(recently debated in English media policy), 'differentiation' in capitalist production and 'difference' in consumer sovereignty, 21c future vision of public service broadcasting as one of the 20c institutions.

This study was conducted to confirm the effect on self-efficacy and critical thinking disposition by applying flip learning class to fundamental nursing practice education for nursing students. The study subjects were 42 people in the experimental group and 40 people in the control group who were allowed to participate in the study. Data analysis was statistically processed using SPSS/WIN 24.0 program. As a result of this study, the self-efficacy score of the experimental group who received the flipped learning class increased significantly immediately after class (t=3.49, p=.001) compared to before class, and 10 weeks after class (t=-0.75, p=.456), the effect persisted. The critical thinking disposition score of the experimental group increased significantly immediately after class (t=3.49, p=.001) compared to before class, and the effect persisted 10 weeks after class (t=0.11, p=.913). However, there was no significant difference in the academic self-efficacy and critical thinking disposition scores of the control group who received lecture classes. In other words, it was confirmed from the results of this study that fundamental nursing practice classes applied with flip learning are effective in improving self-efficacy and critical thinking disposition of nursing students. Based on this study, it is suggested that the application of flip learning method should be expanded in the major subject of nursing science.

This study focuses on the increasing supply and consumption of affair dramas on TV with the theme of unconventional 'infidelity', therefore, is an empirical study that reveals factors related to the problem consciousness of married men and women about infidelity dramas that can affect the sexual socialization of married men and women. This study investigates the effect of married men and women's right to sexual self-determination between couples, personal psychological characteristics (emotional maturity, emotional alienation, self-perception), surrounding environmental characteristics (prevalence of extramarital relationships), and demographic background (gender, age, educational background, economic level) on 'the presence or absence of critical consciousness of infidelity dramas'. For the data of this study, an online survey is conducted on married men and women(614 people), and binary logistic analysis is conducted using SPSS. As a result of this analysis, first, 46% of married men and women have a relatively good level of critical awareness of affair dramas, and overall, the level of critical thinking of married men and women about the infidelity dramas is rather low. Second, there is no significant difference between genders in the perception of problems such as 'excessive beautification of infidelity', 'incitement of infidelity' and 'damage of family values', however, married women are more critical than married men regarding 'explicit sexual description', indicating differences according to gender characteristics. Third, for married men, the level of 'self-perception' and 'marital sexual self-determination right' have a significant effect on the critical mind with infidelity dramas. In the case of married women, it is found that 'the right to sexual self-determination' between married couples and 'emotional alienation' have a significant effect on 'the presence or absence of critical consciousness of infidelity dramas'.

The purpose of this study was to introduce a practical model to enhance creative and critical thinking skills through hypotheses generating activities for students. The 2007 Science National Curricula stresses the need for the enhancement of creative thinking skills for our students. The definition for the creativity in the narrow sense is the divergent thinking skills. The definition of the critical thinking skills is the strong sense of those skills. This model shows the use of the divergent thinking skills and convergent thinking skills together. The divergent thinking skills has been developed by making three alternative explanations about the causal question within a group of students by active discussion. The following procedure includes the selection of the most provable of the three explanations within a group of students also by active discussions. This process needs convergent thinking skills as well as critical thinking skills. This model can be used easily by exchanging from the one explanation about the causal question in any inquiry teaching strategy to three explanations about one. Although the partial modified strategy shows a small difference from any inquiry teaching strategy, but the effect of the enhancement of the creative thinking skills for our students shows significantly better (p<.05). More detailed study will be carried out in the near future.

We have presented characteristics of a transitional behavior from a premixed flame to a triple flame in a lifted flame according to the change of equivalence ratio. The experimental apparatus consisted of a slot burner and a contraction nozzle for a lifted flame. As concentration difference of the both side of slot burner increases, the shape of flame changed from a premixed flame to a triple flame, and the liftoff height is decreased to the minimum value and then increase again. Around this minimum point, it is confirmed a transition regime from premixed flame to triple flame. Consequently, the experimental results of the liftoff height, flame curvature and luminescence intensity showed that the stabilized laminar lifted flame regime is categorized by regimes of premixed flame, triple flame and critical flame. In the visualization experiment of smoke wire, the flow divergence and redirection reappeared in premixed flame as well as triple flame. Thus we cannot express the flame front of lifted flame has a behavior of triple flame with only flow divergence and redirection. To differentiate triple flame and premixed flame, ${\Phi}$ value of partially premixed fraction is employed. The partially premixed fraction ${\Phi}$ was constant in premixed flame. In critical flame small gradient appears over the whole regime. In triple flame, typical diffusion flame shape is obtained as parabolic distribution type due to diffusion flame trailing.

A model of cooperative learning, Pair Programming was applied to regular class for middle school students. Algorithm and programming skill were taught through the pair programming for two week and the achievement was analyzed based on 4Cs(Critical thinking, Communication, Collaboration, Creativity) proposed by the NEA(National Education Association). The control group was statistically significant on Critical Thinking between pre-test and post-test1, while the experimental group was statistically significant on all measurements of 4Cs. Between pre-test and post-test2, the control group showed overall little difference in range of 0.2 points on the 4Cs average scores. while the experimental group was statistically significant on all measurements of 4Cs. Between post-test1 and post-test2, there was no significant difference on 4Cs average scores in both groups. The experimental group showed higher score results on all 4Cs than the control group. This study verifies that the benefits of Pair Programming on 4Cs.
