  • Purpose: The purpose of this study is to investigate the relationship between eating disorders, body image, and self-esteem of female university students. Methods: A total 123 university female students were recruited in April 2009. Data was collected by using questionnaires. The collected data was analysed by SPSS/WIN using frequency, percentage, mean, standard deviation, ANOVA, & Pearson correlation coefficient. Results: As defined by body mass index (BMI), the obese subjects were rare (8.9%) and the rest (91.1%) was under weight or normal. More than 51.2% of the subjects perceived their weight as overweight, while 8.9% of the women were obese as defined by BMI. Eighty-eight percent of the subjects were not satisfied with their body shape. The total mean score of anorexia nervosa was higher than bulimia nervosa. The scores of eating disorders did not differ significantly by the BMI score. The score of body image was highest in the group of the overweight. There was high positive correlation between self-esteem and body image. Conclusion: To ensure resonable body image and weight control behaviors in female university students, education should be reinforsed. Therefore, nursing intervention programs for cognitive changes correcting the understanding about body image need to be developed.

  • This paper examines the concept of "tradition" for Indigenous Peoples as a construct of reality developed through the lens of Western scholarship and American Indian perspectives. The resulting notions of American Indian tradition constructed by a Western point of view, has been incorporated into the thinking of Western peoples as well as those of American Indians. Possible reasons for this include the lasting effects of colonialism and current mass media and the description of cultural "others" through the Western sciences of Anthropology and Musicology. A definition of what is valid or important in defining "traditional culture" for members of an Indigenous community may utilize significantly different measures than those of Western scholars. In order to illustrate this, the author uses two treatises focusing on the Indigenous American Indian cultures of communities in Eastern North America incorporating Indigenous points of view. One of these two books provides a focus on connections between language and culture and the other on ethnomusicology. From both of these perspectives, traditional identity is seen as continuing in the present day through persistent perceptions of reality, linked to community social performance. These perceptions and their accompanying indexes to tradition are still present despite the disappearance of or frequent changes in the surface forms of both language and manufactured cultural items. The emphasis on "legitimate" or "real" tradition is tied to performance within an ongoing cultural community rather than to Western constructions of what is real found in past descriptions of cultures. An alternative view of "valid" tradition and its relationship to Indigenous identity, needs to incorporate Indigenous perspectives rather than depend on constructions developed using non-Indigenous Western frameworks.

  • The Korea railway design trends has been developed by the change of the society and culture through the consideration of the history of railway. The railway design trends is as the vehicles in the external form of railways, instantly means to plan and create the value added something like the form of the exterior design. The railway design has been changing form instinctive methods to settle the mass transport of the early days, to sensitive methods to pursue the railway culture centering around human being. As dividing by the style's change of railway in image scale aspects between 1800's and 2005 according to the life environment into the external nation, there are big differences so that is to study the development history of the railway design accordingly each nation (Korea, United Kingdom, Germany, France, Japan) and the style's change, to confirm into the design applied in society and culture needs, and to analyze by a year in changes of the environment and the railway design history. This paper analyzed railway introduced as railway models by top 4 nation (United Kingdom, Germany, France, Japan) and Korea in the past years(1800-2005) for their Korea railway design trends by image scale positioning.

  • The observed ocean barotropic circulation is not completely explained by the classical wind-driven circulation theory. Although it is believed that the thermohaline forcing plays a role in the ocean barotropic circulation to some degree, how much the thermohaline forcing contributes to the barotropic circulation is not well known. The role of thermohaline circulation driven by changes in temperature and salinity in the Southern Ocean (SO) water masses on the Antarctic Circumpolar Current (ACC) transport is investigated using a coupled ocean - atmosphere - sea ice - land surface climate system model in a Last Glacial Maximum (LGM) context. Withthe implementation of glacial boundary conditions in a coupled model, a substantial increase in the ACC transport by about 75% in 80 years of integration and 25% in the near LGM equilibrium is obtained despite of the decreases in the magnitude of wind stresses over the SO by 33% in the transient time and 20% in the near-equilibrium. This result suggests that the increase in the barotropic ACC transport is due to factors other than the wind forcing. The change in ocean thermohaline circulation in the SO seems to play a significant role in enhancing the ACC transport in association with the change in the bottom pressure torque.

  • Wheat wild relatives that have never been domesticated contained useful genetic resources such as the resistance to abiotic and biotic stresses. Leymus racemosus is one of the wild species. It can grow in a harsh environment like seaside and distribute by healthy rhizomes. Also, it has a useful genetic resource such as salt tolerance and different diseases resistance. Wheat (Triticum aestivum L. cv. Chinese Spring; CS) was crossed with L. racemosus. Wheat-L. racemosus disomic addition lines were produced. The purpose of this study is to identify protein expression in each disomic addition line compared to CS. We performed two-dimensional electrophoresis. Two-dimensional gels stained with coomassie brilliant blue (CBB), a total of 1566 differentially expressed proteins were identified by Progenesis Same Spots software from the cultivars. However, a total of 90 protein spots were identified to be either present or absent or showing significantly differential expression when the difference threshold was set to more than 1.5 fold. However, out of the 90 differentially protein spots, a total of 74 spots were sorted for mass spectrometry analysis. The identified proteins may provide important clues for better understanding the molecular changes in the chromosomes carrying Leymus racemosus.

  • The $4^{th}$ industrial revolution refers to an era where machines capable of outperforming humans are created. In light of the 4th industrial revolution, university students are demanded problem solving abilities, critical thinking abilities, and problem discovering abilities as general and basic abilities. The need for changes in the university level communication education for engineering students remains imperative in this constantly changing social environment. The era where education is conducted only in classrooms is over. This paper discusses the need for diversified education such as the integration of online and offline education, the reinforcement of learning outside of the classroom as well as an education model that transcends formal and informal education such as games and activities that induce self-learning, both intentional and non-intentional learning, and the utilization of mass media and social networking systems. Through providing an education model that assesses and utilizes the data gained from the learning process provided above, this paper widens the perception of future education methods in the 4th industrial revolution.

  • A damage estimation method for support structure of offshore wind turbine using modal parameters is presented for effective structural health monitoring. Natural frequencies and mode shapes for a support structure with monopile of an offshore wind turbine were calculated considering soil condition and added mass. A neural network was learned based on training patterns generated by the changes of natural frequency and mode shape due to various damages. Natural frequencies and mode shapes for 10 prospective damage cases were input to the trained neural network for damage estimation. The identified damage locations and severities agreed reasonably well with the accurate damages. Multi-damage cases could also be successfully estimated. Enhancement of estimation result using another parameters as input to neural network will be carried out by further study. Proposed method could be applied to other type of support structure of offshore wind turbine for structural health monitoring.

  • This study was designed and performed to identify the effects of oriental medical therapy on hwabyung patients by investigating the life events as the cause of Hwabyung, recent stress perception which influences the clinical appearances and change of symptoms by means of objective scales. 1. Through life events rating scale, life events are reported as follows, in the order of majority. Health, discord within family, martial life, friendship and interest, religion etc. Hwabyung patients experienced negative stress much more than positive stress. 2. Through the GARS (Global Assessment of Recent Stress), there were some significant decreases of stress perception in stress4(stress of sickness or injury), stress7(stress of change or no change in routine) and stress8(overall global stress)(p<0.05, respectively), but there were no significant decreases in five items out of eight items. 3. There were significant decreases of all rated symptoms(feeling of chest oppressed, stuffy in the chest or epigastric mass, feeling of something pushing-up, flushing of body or face, abrupt impulsion of anger, resentment), which were checked weekly for 4 times (p<0.05, respectively). In this study the symptoms of hwabyung were improved regardless of stress perception. It means that hwabyung can be improved significantly with oriental medical therapy.

  • This study investigated microstructural changes of cured urea-formaldehyde (UF) resins mixed with aqueous rubber latex emulsion after intentional acid etching. Transmission electron microscopy (TEM) was used in order to better understand a hydrolytic degradation process of cured UF resins responsible for the formaldehyde emission from wood-based composite panels. A liquid UF resin with a formaldehyde to urea (F/U) molar ratio 1.0 was mixed with a rubber latex emulsion at three different mixing mass ratios (UF resin to latex = 30:70, 50:50, and 70:30). The rate of curing of the liquid modified UF resins decreased with an increase of the rubber latex proportion as determined by differential scanning calorimetry (DSC) measurement. Ultrathin sections of modified and cured UF resin films were exposed to hydrochloric acid etching in order to mimic a certain hydrolytic degradation. TEM observation showed spherical particles and various cavities in the cured UF resins after the acid etching, indicating that the acid etching had hydrolytically degraded some part of the cured UF resin by acid hydrolysis, also showing spherical particles of cured UF resin dispersed in the latex matrix. These results suggested that spherical structures of cured UF resin might play an important role in hindering the hydrolysis degradation of cured UF resin.

  • A 42-year-old woman with short-term memory loss visited Gangnam Severance Hospital, and her chest X-ray and computed tomography revealed a right anterior mediastinal mass. On hospital day two, she suddenly presented personality changes and a drowsy mental status, so she required ventilator care in the intensive care unit. She underwent thymectomy, and was pathologically diagnosed with thymoma, type B1. Her mental status eventually recovered by postoperative day 90. Paraneoplastic encephalopathy associated with thymoma is very rare, and symptoms can be improved by thymectomy. We report a case of paraneoplastic encephalopathy associated with a thymoma.
