Purpose: The purpose of this study was to investigate the relationship between end of life care competencies and terminal care stress of nurses in long term care hospitals. Methods: For this study, 140 nurses were sampled among those that have over 6-month end of life care experience and were working at long term care hospitals located in A city and C city of Chungcheongnam-do. Using a questionnaire, data were collected from January 2018 through March 2018. Data were analyzed using the SPSS, Windows version 21.0, according to the purpose of the study and analyzed by descriptive statistics, t-test, one way ANOVA, $Sch\acute{e}ffe^{\prime}s$ test, and Pearson's correlation coefficient. Results: The mean score on terminal care stress of nurses was above the normal level. The scores on end of life care competencies significantly varied by age, total career at hospitals, death/hospice and palliative care education, and bereavement experience. The mean score of end of life care competencies was negatively correlated with the mean score of lack of knowledge and skills among the subitems of the terminal care stress category (r=-0.260, P=0.002). Conclusion: To decrease the terminal care stress of long term care hospital nurses, it is suggested to carry out end of life care education tailored to nurses characteristics.

A Dead-end mode operation is one of the best way to maximize the gas usage rate. But, some components of fuel cell stack like gas diffusion layer(GDL) or membrane can be damaged in dead-end mode operation. In this study, a Large Scale Polymer electrolyte membrane fuel cell(PEMFC) for a dead-end operation has been developed. The stack is composed with 4 cells which has over 400cm2 of active area. Hydrogen is used as a fuel, and oxygen is used as a oxidant. The dead-end operation performance was evaluated by a long-term dead-end mode operation. The fuel cell stack is operated over 1,500 hours in dead-end mode operating fuel cell test station. And the performance change of the fuel cell stack was investigated.

The term "philosophizing art" was coined by Arthur Danto, who tried to define new forms of art, especially Andy Warhol's pop art appeared in New York after 1960's, which could not be explained by traditional concept of "representation". As Danto said "the term 'philosophizing art' is unclear, whether art discusses philosophical issues or art is the object of philosophic discussions", it does not seem like Danto himself had a specific idea when he used this term. The background for Danto coining this term derives from the fact that the old art concept such as denotation and connotation could not fully explain phenomenalistic aspects of concept art which appeared frequently at that time. Many articles in his book "philosophizing art", in which many of his criticism are included, mainly say that art begins philosophizing by dealing with not mimesis or representation but concepts. According to his argument, the history of western art, which has been consisted of mimesis and representation, has come to end when art is about physically embodied with meaning. Of course, as Danto say so, what goes to end is not art itself, but the narrative of art. It means master narrative saying art should be shown different from nature or artificial daily product is over. Danto could not find principals of mimesis and representation which had been main logic in the western art history, when he saw Andy Warhol's Brillo Boxes at Stable Gallery, New York in 1964. Danto questioned "if we can not distinguish Brillo box's artistic aspects visually from other factory-made products, how can we distinguish art from non-art", By answering those questions, he discovered two facts which made him realize the end of Art: One is there is no special way in which works of art have to be shown or has to exist. Therefore, art history has proven that commercial boxes, trashes and files of underwear can be a work of art. The other is we have fully recognized it at the end of 20thcentury. Danto confessed that through Brillo Boxes, he realized the works of art are decided by something can not be seen by eyes, not by distinguished differences by looking at it. This thesis is trying to show personal understanding about art, philosophy and discourses surrounding them and to figure out how Dante opened a new world to art criticism by using new definitions such as 'end of art' and 'philosophizing art' which Danto used to explain inner aspects of art.

A hybrid approach using Long Short Term Memory (LSTM) Recurrent Neural Network (RNN) has showed great improvement in speech recognition accuracy. For training acoustic model based on hybrid approach, it requires forced alignment of HMM state sequence from Gaussian Mixture Model (GMM)-Hidden Markov Model (HMM). However, high computation time for training GMM-HMM is required. This paper proposes an end-to-end approach for LSTM RNN-based Korean speech recognition to improve learning speed. A Connectionist Temporal Classification (CTC) algorithm is proposed to implement this approach. The proposed method showed almost equal performance in recognition rate, while the learning speed is 1.27 times faster.

Purpose: This retrospective study reports the intermediate-term clinical outcomes including the practical function in daily and sports activities after total ankle arthroplasty for end-stage rheumatoid arthritis, as well as the effects of modification of perioperative anti-rheumatic medications. Materials and Methods: Twelve patients were followed for a minimum of 2 years after total ankle replacement for end-stage rheumatoid arthritis. Perioperative anti-rheumatic medications in all patients were modified based on a specific guideline. Clinical evaluations consisted of American Orthopaedic Foot and Ankle Society (AOFAS) scores, Foot and Ankle Outcome Score (FAOS), and Foot and Ankle Ability Measure (FAAM) scores. Periodic radiographic evaluation was conducted to detect changes in ankle alignment and postoperative complications. Results: Mean AOFAS, FAOS, and FAAM scores improved significantly from 37.5 to 81.2, 39.1 to 72.4, and 33.8 to 64.0 points at final follow-up, respectively (p<0.001). Functional outcomes in daily and sports activities at final follow-up were found to be 76.5 and 55.8 points for the FAOS and 70.5 and 57.5 points for the FAAM, respectively. As early postoperative complications, there was one case of local wound necrosis, one case of medial malleolar fracture, and one case of deep peroneal nerve injury. Radiological evaluation revealed two cases of asymptomatic heterotopic ossification and one case of progressive arthritis in the talonavicular joint. Reoperation was performed in only one patient (8.3%) with a medial soft tissue impingement at a mean of 35.6 months follow-up. Conclusion: Total ankle arthroplasty appears to be an effective surgical option for end-stage rheumatoid arthritis. Practical functions in daily and sports activities were significantly improved at intermediate-term follow-up. Modification of perioperative anti-rheumatic medications can be one of the solutions to reduce the postoperative complication rate.

Purpose: End-stage ankle arthritis is frequently combined with ankle-hindfoot deformity or ankle instability and therefore additional surgical procedures are often required when performing total ankle arthroplasty. We report the short term clinical and radiographic results of the total ankle arthroplasty with/without the combined adjunctive surgical procedures. Materials and Methods: The study is based on the 17 ankles (16 patients) of end-stage ankle arthritis that were treated with $HINTEGRA^{(R)}$ Total ankle prosthesis (Newdeal, Lyons, France) total ankle arthroplasty (TAA) from 2004 to 2007 with at least 12 months follow-up. The combined adjunctive procedures as well as the VAS pain score, AOFAS score, radiographic measurements and patient satisfactions were evaluated. Results: Average follow-up period was 29 months (13${\sim}$55 months), and the age was average 62 years (39${\sim}$75 years) old. Among total of 17 ankles, varus deformity and lateral ankle instability were found in 4 cases and 3 cases respectively. Twenty additional procedures such as Achilles triple hemisection (9), calcaneal displacement osteotomy (4) and lateral ankle ligament reconstruction (3) were performed in adjunct to TAA in 13 ankles. VAS pain score improved from preoperative average 8.4 (7${\sim}$10) to 2.0 (0${\sim}$5) and the AOFAS functional score improved from 41.8 points (13${\sim}$71 points) to 90.6 (77${\sim}$100 points) at final follow-up. Ninety-four percent of the patients were satisfied with the surgery. Conclusion: We confirmed that many adjunctive combined surgical procedures are often necessary in addressing the end-stage ankle arthritis (74%) with total ankle arthroplasty. We also achieved quite good clinical and radiographic short term results, although the long term follow-up study with larger number of cases are needed in the future.

The term project executed at the university is a learner-centered learning method in which students select their topics, draw up their plans, and produce results by themselves based on the content they have learned during the semester. Through the term-end project of the subjects relating software, students learn various techniques for the programming language and produce the outcomes of their project by the creative program development process. However, non-computer majors who take software course as liberal arts subjects have difficulty in understanding the programming language, so it is necessary to provide feedback from their professor for encouraging students in carrying out their projects smoothly. Therefore, a feedback method by the discussions between a professor and learners that can be applied to the term-end project of programming subject for the non-computer majors is proposed. The proposed method was apply to the actual term-end projects and the meaningful results were confirmed through the analysis of the project processes and outcomes.

Purpose: The purpose of this study was to explore the subjective experience of moral distress among nurses working in long-term care hospitals. Methods: A phenomenological approach was used for the study. Data were collected from May to July, 2019 using open-ended questions during in-depth interviews. Participants were nurses working in long-term care hospitals and had reported experiences of moral distress. Nine nurses participated in this study. Results: Three themes emerged from the analysis using Colaizzi's method: (1) confusion and distress about the meaning of care, (2) a feeling of helplessness caused by connivance, (3) enduring in the organization. Conclusion: Sufficient labor supply, environmental improvements, programs for improving interpersonal skills, education and counseling on end-of-life care, and recognition improvement about long-term care hospitals are suggested to reduce the moral distress of long-term care hospital nurses.

This study attempted to demonstrate that the integration of the two premises in linear syllogism is mediated by the middle term the term that is repeated in the two premises. In Experiment 1. we examined whether representing the middle term is more important than representing the end terms. We asked a question to each premise. Depending on the order of the questions either the two end terms or the middle term became the answer in both premises. Participants solved the problems better when the middle term became the answer suggesting that it is more important to represent the middle term than the end terms. In Experiment 2 we examined whether additional processing is needed for the integration beyond establishing co-referential link through the middle term. We pronominalized the middle term in the second premise and provided two kinds of information to disambiguate the pronoun. In the direct information condition we provided information about who the pronoun is whereas in the indirect information condition we provided information about the relative location of the pronoun. Participants solved the problems more quickly in the indirect information condition than in the direct information condition indicating that mere co-referential link was not enough and that the relative location of the middle term needs to be computed for the integration of the two premises.
