This paper is a descriptive study that aims to investigate attitudes towards menstruation, symptoms and coping behaviors in order to develop a program for building positive attitudes toward menstruation in primary school students. The mean age of menarche was 12.3 years, and students generally showed negative attitudes towards menstruation. Students who experienced menarche had relatively more positive attitudes than those who did not. However, no significant difference was exhibited. Menstrual symptoms occurred rarely or at a moderate level by showing a low score of 2.12 points. Of all sub-factors, 'pain' was the most serious. The most common coping behaviors during menstruation was 'I take a warm shower' and 'I take a rest or nap', while respondents rarely checked 'I take vitamin B supplements' and 'I take painkiller'. Based on the above findings, the study intends to perform a systematic study to further identify the factors affecting menstrual attitudes in primary school students. In addition, this paper suggests effective healthcare education on menstruation to build positive attitudes towards menstruation and education and counseling programs for adopting appropriate coping strategies to deal with menstrual symptoms.

In impermeable ground, water pressure is applied due to discontinuity such as joint or fissure. Therefore, water pressure should be considered in design regardless of ground condition. However, when the shape of segmental lining is circular, water pressure may reduce the lining member force, so it is important to define the assumption and the concept of design in case of high water pressure. This paper presents the concepts of design of the lining of shield tunnel at high water pressure and in impermeable ground condition. In addition, the member forces in various load conditions were compared in this study. (elastic equation, closed form solutions, beam-spring model).

2000s Korean cinema was influenced by capital, so it chose the way of Allegory instead of talking directly about sensitive issues. A representative movie director is Park Chan Wook who directed The Vengeance Trilogy. , The final part of Park Chan Wook's The Vengeance Trilogy, reflected Baroque Aesthetics. I analyzed focusing on Walter Benjamin's Allegory notion in this paper. Walter Benjamin said Allegory is different from a symbol which is represented by totality. Allegory means to reconstruct the fragment instinctively and to expose something repressed. The German Tragic Drama during the baroque period reflects this well. It is my argument that Park Chan Wook incorporated these underlying themes from German Tragic Drama into . He deconstructed the liberation and the birth myth of a nation, and he restored the socialist and anarchist who were completely excluded from history.

The purpose of this study was to explore the level of anger and social support and to identify factors affecting anger in elderly women. This was a cross-sectional descriptive survey. A convenience sample of 155 elderly women was recruited from two senior welfare centers and three nursing homes in J city. Data were collected from June 15 to July 15, 2010 through interviews using a structured questionnaire. Data were analyzed with descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple linear regression using the SPSS WIN 18.0 program. The level of social support and anger was 3.73 and 2.72 out of 5, respectively. Anger was statistically significantly different according to type of residence (B=0.21, t=2.42, ${\rho}$=.017), psychiatric medication (B=0.66, t=4.93, ${\rho}$ <.001), physical medication (B=0.41, t=4.22, ${\rho}$ <.001), and evaluation support (B=-0.15, t=-3.00, ${\rho}$=.004), and these accounted 33.0% of anger. Providing proper information and developing social support program would be useful for managing anger of elderly women.

This study was a descriptive research investigating the impact of simulation-based learning on the problem solving process and clinical competence of new nurses. The 202 participants were new nurses who have provided nursing care for less than 12 months have experienced simulation-based learning more than once in their undergraduate courses. This study found that the number of times participants have experienced the simulation-based learning had no correlation with their problem solving process and clinical competence, but simulation design features correlated with their problem solving process and clinical competence. The results of clustering analysis that examined differences in the effects on problem solving process and clinical competence by classifying simulation design features by clustering also showed significant differences. This study has confirmed the importance of simulation design to simulation-based learning in nursing education. We hope that the findings of the study will be used for effective operation of simulation-based learning. In the future, objective assessment methods will be required to evaluate the effects of simulation-based learning provided in undergraduate courses on nurses' clinical competence.

The objective of the present study is to develop methodology for the assessment of combustion stability of liquid rocket injectors. To simulate actual combustion occurring inside of a thrust chamber, a fullscale injector has been employed in the study, which bums gaseous oxygen and mixture of methane and propane. The main idea of the experiment is that the mixing mechanism is considered as a dominant factor significantly affecting combustion instability in a fullscale thrust chamber. A single split triplet injector has been used with an open-end cylindrical combustion chamber. The characteristics revealed by excited dynamic pressures in gaseous combustion show degrees of relative acoustic damping depending on operating conditions. Upon test results, the direct comparison between various types of injectors can be realized for the selection of the best design among prospective injectors.

is basically based on a written history but is narrated for an unwritten history with imagination. This study explored whether viewers of tow films and regard them as a real story or an unreal story. Analysis of film contents and data from a nationwide online survey(N = 300) were executed. This study found the following. First, viewers consider a true story but a imaginary story. Second, viewers show different ideologial and emcotional evaluation, and strength of memory between two films. Finally, viewers are not likely to evaluate performative value of two history films, which suggest a pluralistic interpretation of history, as they regard the films as an imaginary story or a recreation.
