Purpose: This study was to construct a structural equational model for explaining and predicting job stress of intensive care unit (ICU) nurses based on the Integrated model of stress of Ivancevich and Matteson (1980). Methods: The subjects of this study were 220 nurses at ICU. The data were collected from August 5 to 30, 2013 through self-reporting questionnaire survey. Results: According to the hypothetical model of this study, perceived nursing practice environment, perceived role conflict, perceived transformational leadership and perceived self-esteem showed statistically significant effects on job stress of ICU nurses directly. Professional self-concept indirectly affect job stress of ICU nurses. In conclusion, job stress of ICU nurses was directly influenced by nursing practice environment, role conflict, transformational leadership and self-esteem. Professional self-concept of the relationships among variables did not have a direct impact on job stress. Conclusion: Based on the results of this study, it is needed to develop stress management measures and programs considering these variables in order to adequately manage job stress of ICU nurses.

Objective : Frameless stereotactic aspiration of a hematoma can be the one of the treatment options for spontaneous intracerebral hemorrhage in the basal ganglia. Postoperative hematoma enlargement, however, can be a serious complication of intracranial surgery that frequently results in severe neurological deficit and even death. Therefore, it is important to identify the risk factors of postoperative hematoma growth. Methods : During a 13-year period, 101 patients underwent minimally invasive frameless stereotactic aspiration for basal ganglia hematoma. Patients were classified into two groups according to whether or not they had postoperative hematoma enlargement in a computed tomography scan. Baseline demographic data and several risk factors, such as hypertension, preoperative hematoma growth, antiplatelet medication, presence of concomitant intraventricular hemorrhage (IVH), were analysed via a univariate statistical study. Results : Nine of 101 patients (8.9%) showed hematoma enlargement after frameless stereotactic aspiration. Among the various risk factors, concomitant IVH and antiplatelet medication were found to be significantly associated with postoperative enlargement of hematomas. Conclusion : In conclusion, our study revealed that aspirin use and concomitant IVH are factors associated with hematoma enlargement subsequent to frameless stereotactic aspiration for basal ganglia hematoma.

Purpose : This study is conducted to research the attitude of social workers toward withdrawing life sustaining treatment and compare and analyze the different types of their attitudes. Methods : Research design of this study is Q methodology approach. The study population is 23 social workers. Q sample to investigate the attitude of social workers toward withdrawing life sustaining treatment included 30 statements. After listening to the purpose and method of the study, the 23 social workers agreed to fill out a survey asking sociodemographic information and have been forced to be distributed in 9 scale Q-sample. Results : The collected data was processed through QUANL PC program, sorted into 3 types as followings. The first type was 'the pursuit of quality of life' that the quality of life is more important than the length of life, the second 'choosing to withdraw life sustaining treatment' that they want to write or encourage family to write advanced directive, the third 'withholding life sustaining treatment' regardless of the cost. Conclusion : In conclusion, the social workers attitudes toward withdrawing life sustaining treatment were grouped as three different types, the first type was 'the pursuit of quality of life', the second 'choosing to withdraw life sustaining treatment', the third 'withholding life sustaining treatment'.

Purpose : The purpose of study was aimed to identify whether the painless dynamic PNF techniques makes any differences in reducing lymphedema by applying this technique to lymphedema patients, and to provide the basic reference data for the purpose of applying to lymphedema patients. Methods : A total of 40 women participated in this study, and they did PNF techniques before applying lymph compression bandages. Group 1 of 20 subjects performed PNF techniques three times a week with 30 minutes each time. Group 2 of 20 subjects only practiced edema reducing massaging for 30 minutes. Results : In addition, the interaction between treatment method and treatment time was significant (p<.0001), which indicates that the changes in edema rates by measurement times appear differently according to treatment methods. In this study, it means that the 'PNF techniques' group has a steeper slope of decline than the 'message' group. Conclusion : In conclusion, both massaging and PNF techniques helped to lower edema rates. Four weeks after the beginning of treatment, PNF techniques was exhibited as generating a large degree of decline in edema rates than massaging.

Science museum are dealing with exhibits on field of changing science and technology, and previous research suggested that exhibits replacement should carried out at least every 5 years. In order to efficiently replace exhibits within a limited budget, various studies analyzed visitors' preferences to exhibits. Recently, studies use various technologies to collect the data on visitors' preferences automatically, but almost of studies had a high dependency on their visitors such as visitors needed to carry specific sub-devices in the museums for gathering data. As complementing the limitations of previous research, this study introduces the improved method which is able to automatically collect and quantify visitors' preferences to exhibits using TensorFlow, a deep learning technology. By the proposed analysis method, it was possible to collect 2,520 data of visitors' experience on exhibits in totality. Based on collected data, attraction power and holding power indicating the preference of visitors on exhibits were able to be calculated. The result also confirmed antecedent research conclusion that the attraction power and holding power of the exhibit which consists of 3 dimensional structures work are higher than other exhibits. As a conclusion, the proposed method will provide more convenient data collection method for detecting visitors' preference.

Objectives: The purpose of this study was to investigate the ameliorative effects of the Epimedium koreanum Nakai (EK) on menopausal obesity in mice. Methods: To induce the menopausal obesity, female C57BL/6J mice were ovariectomized and fed with high fat diet for 12 weeks. 17β-estradiol was injected as a positive control and the extract of EK was orally administered 5 times per week for 6 weeks. Body weight, uterine weight and visceral fat weight were measured. The size of the adipocyte in visceral fat tissues was estimated by Hematoxylin and eosin staining. Fasting glucose level was estimated in serum. Results: Body weight and visceral fat weight were significantly decreased by EK treatment, while the uterine weight/body weight was increased in high fat diet-fed ovariectomized mice. The diameter of adipocyte in the visceral fat tissues was markedly reduced in EK-treated menopausal obese mice. In addition, the fasting blood glucose level was inhibited by oral EK administration. Conclusion: In conclusion, these results showed that EK has ameliorative effects on overweight after menopause. EK could be one of the alternative therapy for treating menopausal obesity.

Since 1960, the change of architectural trend was dominated by two factors ; the one, the introduction of theory of language (including semantic, syntactic, pragmatic, linguistic, semiotic, structuralism, post-structurism) in design concept, the other, the adaption of high technology in building construction. In particular, the theory of language played an important role in the emergence of new tendency, which could be the alternative of modern architecture. Post-modernism and Typology in the 1960-70s, Deconstructivism in the 1980s and 'Folding' architecture in the 1990s, have continually borrowed a theoretical base from the thee of language. Placing the focus on the relation of contemporary architecture and theory of language with the interdisciplinary view, this study comes to the conclusion that the diverse architectural tendencies since 1960 depend on the 'champ d'enonce', which Michel Foucault, French philosopher, defined in his . The writings of many architects, like Robert Venturi, Micheal Graves, Aldo Rossi, Peter Eisenman, Rem Koolhaas, Bernard Tschumi, Gerg Lynn demonstrate our conclusion. This is an important finding which make possible consistent understanding about contemporary architecture.
