This study was conducted to investigate the effects of child nursing simulation using standardized patient on nursing student's anxiety, self-efficacy, and critical thinking disposition. A one group pre test-post test design was used. The subjects of the study were 62 students in the nursing department and 4th year students at the university in C city. The hospitalized child nursing simulation was conducted for approximately 3.5 hours, including 60 minutes of pre-study and orientation, 60-80 minutes of hands-on scenarios, and 30 minutes of reflection diary writing and debriefing. The data collection was conducted from March to December 2016. Statistical analyses of the collected data were conducted, including t-tests, Pearson's correlation coefficient, and Cronbach's ${\alpha}$. Analyses were conducted using SPSS 21.0. The results of the study showed that anxiety (p <.001) was significantly lower and self-efficacy (p<.001) and critical thinking disposition (p<.001) were higher. Therefore, we propose that various scenarios for simulation practice that utilize standardized patients to enhance core nursing abilities be developed.

The repair technique of rotator cuff tear has been markedly developed in recent years. When the natural history of rotator cuff tear was followed, the size of rotator cuff tear increased with time. The fatty infiltration which would come at the later period of rotator cuff tear and the rotator cuff tear arthropathy which would be occurred after massive rotator cuff tear may be the important factors in predicting the prognosis of rotator cuff tear or determining the timing of surgery. Because moderate supraspinatus fatty infiltration appeared an average of 3 years after onset of symptoms, the repair of rotator cuff tear was recommended to be performed before that. And if there was massive rotator cuff tear with cuff tear arthropathy, it was recommended that the rotator cuff repair should be performed before the occurrence of the narrowing of acromiohumeral interval. The techniques of arthroscopic rotator cuff repair were mainly the single row repair and the double row repair. The former is good in view of time consuming and cost, but the latter is superior in view of biomechanics. To maintain the benefit in biomechanics of double row technique and reduce the time of surgery, the suture-bridge technique was invented and widely used recently. There are several modified techniques in arthroscopic suture-bridge technique according to the characteristics of rotator cuff tear.

This paper is to reconsider comprehensively and systematically major issues on transnational immigrants, increased rapidly since the beginning of the 1990s, and their impacts on socio-spatial changes in S. Korea. Foreign immigrants who have moved on the contexts of unevenness of globalization and advancces in transport & telecommunication technology on the global level and of economic development and shortage of cheap and unskilled workers have been distributed unevenly, concentrating on the Capital region and local areas with industrial complexes. Foreign workers seems to have some negative influences on regional economies in the long-term, though positive in the short-term. Domestic people seem to have an ambivalent attitude which accepts necessity of multi-culture, while simultaneously continues to be self-confident on ethnic homogeneity. The Korean government has launched multicultural policies for foreign immigrants by the mid-2000, but still continues some policies with assimilationism and differential exclusionism, marginalizing them socio-spatially, while lacking local government's policy and programmes. In conclusion, in order to resolve these problems and to transfer multicultural societal space of Korea, a geography of transnational migration which promotes especially discourse and policy with authentic multiculturalism, extending roles of local government, and ensuring glocal citizenships.

Recently, concepts of multicultural society and/or multiculturalism have been not only widely discussed across several disciplines, but also actively promoted in government's policy, as the in-flow of foreign immigrants has increased rapidly. This paper suggests the term 'multicultural space' instead of multicultural society in a sense that both international migration of immigrants and their accommodation to a certain locality presuppose a spatial dimension. This paper also points out that the term multiculturalsim should be used very carefully, because this term includes a normative character implied in a sense of recognition of ethnic and cultural diversity and difference on the one hand, and an ideological one reflected on strategic policies of capital and the state on the other. On the basis of recognition of these problems, this paper tries to reformulate spatially the concept of muticultural society which has been supposed to be constructed due to rapidly increasing foreign immigrants, emphasizing some usefulness of multi-scalar approach. It then analyzes economic and political contexts of transnational migration, providing a criticism of multiculturalism as an ideological logic of capital and the state in transnational captialism. Finally it put a stress upon importance of struggle for spaces of recognition as a new glocal ethics in the age of post-globalization.

This study was carried out to develop an efficient transformation protocol via particle bombardment with PLBs (protocorm-like bodies) in Phalaenopsis. To achieve this aim, osmoticum treatment and an increasing shooting chances in particle bombardment process were applied for this study. In addition, pCAMBIA3301: ORE7 vector which contains a herbicide-resistance bar gene as a selectable marker and ORE7 gene as a gene of interests were employed. With regard to the increasing chances of shooting in particle bombardment, double shooting was the best results with 1.5 ~ 2.5 times higher than those of a single or triple shooting treatment in the productioon of PPT (D-L-phosphinothricin)-resistant PLBs. However, regeneration rate of shoots in double shooting was not high as a single shooting. Further, double shooting showed 35 ~ 40% higher than that of a single shooting in the frequency of browning. Regarding effects of different osmotic treatments, combination of 0.2 M sorbitol with 0.2 M mannitol showed the best results in transformation efficiency, regeneration of transformants and reduction of browning. Putative transgenic Phalaenopsis plants were analyzed by PCR analysis and confirmed the presence of bar and ORE 7 gene. Also, real-time PCR was conducted by using 21 transgenic plants and showed only 4 plants had one copy of transgene; whereas, the other 17 plants had more than 2 copies of transgene. Transgenic phalaenopsis plants produced in this study were transferred to pots and flowered normally without morphological variations in flower and leaf.

To establish an efficient proliferation and regeneration of PLBs (protocorm-like bodies) of Phalaenopsis plants, a variety of propagation medium types, various concentraions of sucrose as well as liquid and solid type were tested in this study. Further, activated charcoal, citric acid and ascorbic acid were compared whether these agents are suppose to reduce the browning in culture process using PLBs of Phalanopsis plants. With regard to the proper propagation medium, VW medium showed 1.3 ~ 2 times highr than those of other medium in an index of increasing for fresh weight and 50% higher than those of other medium in the frequency of shoot regeneration. However, regarding liquid and solid types of culture, there were no significant differences in the proliferation of PLBs and regeneration of shoots from PLBs. In the experiment for a variety of sucrose concentrations (0 ~ 50 g/l), 10 g of sucrose showed 30 ~ 50% higher than other concentrations in increasing index and 10 ~ 50% higher in the regeneration of shoots from PLBs. Regarding the reduction of browning in tissue culture via PLBs of Phalaenopsis plants, 1 g of activated charcoal showed only 1.5% browning of PLBs cultured. Whereas, other treatments including citric acid and ascorbic acid showed 6 ~ 16% of browning of PLBs. Therefore, activated charcoal was selected as an efficient anti-browning agents for the culture of PLBs in Phalaenopsis plants. Using above-described results can be contibuted to the establishment of mass propagation system using PLBs of Phalaenopsis plants in the future.

The effects of the composition of the dishwashing detergent on interfaces of the oil (O) and the aqueous (W) solution in addition to the cleaning effects of interfacial properties were investigated. Also, the cleaning power of the oil contaminated on the surface of the dish according to each composition and the residuals of the contaminants and the cleaning agent after the washing rinses were evaluated. The removal of contaminated oil on the solid (S) surface in the composition of the cleaning agents used in this study was strongly related to the interfacial properties between the W/O/S, and was particularly dependent on the forward and backward dynamic contact angles. When both contact angles were low at the same time, the permeability of the cleaning solution was so high that the contaminated oil showed a high removal effect. The smaller the interfacial tension of O/W was, the better emulsification of the contaminated oil, the higher the interfacial tension, and the poorer emulsification were achieved. However, the emulsification effect did not significantly affect the cleaning power. In particular, in the case of the cleaner having low interfacial tension, the cleaning material remained on the surface of the solid after washing.

This article is the second one of the continuous study that considering 'body' as important and researching bodies as 'literature-media': the phenomena and functions. The present writer first of all have paid attention to the study of the contrast between pansori and ballet to secure definite, historic and theoretical prospect of this continuous study. In the process, the Korean creative ballets based on Korean classic narratives were illuminated as the glocal culture contents. And then the necessity of citing Korean characteristic rhythm and tune was insisted to acquire the true individuality and identity(What is the reason Chunhyang dances?(I)). The solution is jangdan and chang of pansori. This article aimed the supplementation of detailed and actual arguments to strengthen and formulate the opinion. And then this article desired to estimate the way to improvement of Korean creative ballet by properly citing jangdan and chang with the actual application cases of Korean ballets. Until now, at least pansori have gotten a sort of visual effectiveness: simply be seen and heard as unusual constituent. Thus the necessity of pansori to work motions and choreography beyond the simple usages. Also the way to be extended generally through being refined by the partial applications.

Calla lilies (Zantedeschia spp.) are monocotyledonous ornamental plants which belongs to the Araceae family. After the release of elite calla cultivar, an efficient propagation system is needed for commercial use. Despite the use of conventional propagation methods such as splitting of tubers and rhizomes of calla, rapid and efficient propagation system should be developed. In order to achieve this goal, stem segments contained apical meristems derived from calla lily cultivar (cv. Gag-si) were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations of cytokinin and auxin. This was aimed at inducing embryogenic calluses, shoots and multiple shoots. As a result, about 25% of induction rates of yellow embryogenic calluses were observed with MS medium containing both $0.5mg{\cdot}L^{-1}\;NAA$ and $1.5mg{\cdot}L^{-1}\;BA$ as growth regulators. In the experiments involving the regeneration from embryogenic calluses through shoot formation, MS medium supplemented with $0.5mg{\cdot}L^{-1}\;IAA$ and $2.0mg{\cdot}L^{-1}\;BA$ showed the highest rates at approximately 85 ~ 90% with regard to the formation of shoots in calla. Moreover, multiple shoots needed for rapid propagation were generated when explants were cultured on MS medium supplemented with $0.5mg{\cdot}L^{-1}\;IAA$ and $2.0mg{\cdot}L^{-1}\;BA$ with 40% of formation rate. In this study, the combination of auxin and cytokinin showed positive effects on both the induction of embryogenic calluses, the formation of shoots as well as multiple shoots in calla. The regeneration system described here can contribute to the development of breeding programs of calla in the future.

The popularity of beauty makeup applications has dramatically increased among young Korean female social media users. The current experimental study examined how the use of beauty makeup applications when taking and posting selfies influences social media users' mood, body satisfaction, and self-esteem. A total of 114 female undergraduate students participated in experiments which included two conditions of taking selfies with and without the use of beauty makeup applications. Participants reported their current mood, and body satisfaction as well as self-esteem before and after experiments. Data were analyzed using repeated measures analysis of variances. The significant interactions between experimental groups and time (pre- and post-test) were found for negative mood, positive mood, and body satisfaction. Participants who took selfies using beauty makeup applications were in a significantly better mood compared to those taking selfies without the use of a beauty makeup application. The level of body satisfaction significantly decreased only for women who took selfies without the use of a beauty makeup application. This study extends the current literature of virtual makeup behavior and body image.
