Purpose: This study simulates cardiac arrest situations in 360° virtual reality video clips and general video clips, and compares the correlations between educational media and experience recognition. Methods: Experimental research was carried out on a random control group (n=32) and experimental group (n=32) on March 20, 2019. Results: The groups where participants were trained with the 360° virtual reality video clips and a higher score of experience recognition (p=.047) than the group where participants were trained with the general video clips. Moreover, the subfactors of experience recognition including the sense of presence and vividness (p=.05), immersion (p<.05). experience (p<.01), fantasy factor (p<.05). and content satisfaction (p<.05) were positively correlated. Conclusion: Enhancing vividness and the sense of presence when developing virtual reality videos recorded with a 360° camera is thought to enable experience recognition without any direct interaction.

This study was conducted to develop an optimal composite recipe of nutritional cookies containing oak mushroom (Lentinus edodes) powder that has a high preference score. Oak mushroom(Lentinus edodes) is considered a significantly wholesome food. In addition, the dried oak mushroom(Lentinus edodes) has a better flavor and more nutrients than the fresh oak mushroom since vitamins are activated during the drying process. Wheat flour was partially substituted with Lentinus edodes powder to reduce its content. The optimal sensory composite recipe was determined by making iced cookies which have the advantage of long storage, at 3 concentrations of Lentinus edodes powder, yellow sugar and butter, using the central composite design. In addition, the mixing condition of Lentinus edodes powder cookies was optimized by subjecting the cookies to a sensory evaluation and instrumental analysis using the response surface methodology(RSM). The effects of the addition of the three variables on the quality of Lentinus edodes cookies were assessed in terms of texture, color, spread ratio and sensory evaluation. The results of the sensory evaluation produced very significant values for color, appearance, texture, overall quality(p<0.05), flavor(p<0.01) and the results of instrumental analysis showed significant values in lightness(p<0.05), spread ratio, hardness(p<0.01). As a result, the optimal sensory ratio of Lentinus edodes cookies was determined to be Lentinus edodes powder 10.83g, yellow sugar 61.89 g, and butter 120.0 g.

Objectives : Dementia has emerged as a leading public health problem in elderly persons, and its early detection is important for the treatment of curable cases, and in the educational support for other family members. Although dementia screening tests are available, they have not gained widespread use in community or primary care settings. Our goal was to validate the Tine and Change (T&C) Test, -including its validity and reliability in patients, and to assess it as a simple, standardized method for the screening of dementia in the rural elderly. Methods : The participants in this study comprised of 59 patients from an urban hospital and 405 persons from a rural community aged 65 years or older. The time test evaluated the understanding of clock hands indicating 11:10, and the change test the ability to make 1,000 Won from a group of coins, consisting of one 500, seven 100, and seven 50 Won coins. The T&C ratings were validated against a reference standard based on the physician's diagnosis of the patients. The convergent validity in relation to other cognitive measure, test-retest agreement, and inter-observer reliability were assessed. To assess the relationship between the Korean Mini-Mental State Exam (K-MMSE) and the T&C Test, the mean K-MMSE scores were compared with the results of the T&C Test in the elderly from a rural community. Results The T&C Test had a sensitivity and specificity of 73.0, and 90.9%, and positive and negative predictive values of 93.1, and 66.7%, respectively. The test-retest and inter-observer agreement rates were both 95%. The K-MMSE scores and T&C Test were significantly related in the elderly from a rural community (p<0.01), The T&C Test was not influenced by the educational status. The Time and Change Tests took a mean of 6.3 and 12.7 seconds, respectively, to complete Conclusion : The T&C Test is a simple, accurate and reliable, performance-based tool in the screening for dementia. Because it is quick, and easy-to-use, it is hoped the T&C Test will be used for the widespread cognitive screening of aging populations.

Granuloma is an uncommon benign disease that develops in the process of wound healing. Pharyngeal or laryngeal granuloma can be associated with gastric reflux, mechanical injury or trauma including intubation, voice abuse, or foreign body. 50-year-old female was transferred to our institute with a huge mass occupying the upper aerodigestive tract causing dysphagia. The patient has been suffering from a brain hemorrhage for several months and was kept in bed due to the quadriplegia with stuporous mental status, and was tracheotomized. On examination, the whole oropharynx and hypopharynx was covered by a smooth-surfaced soft big diffuse granular mass, which extended down to the upper trachea through the larynx. The huge granuloma was successfully removed with surgery and was found to have a pedunculating stalk on the oropharyngeal posterior wall with a small mucosal defect, suggestive of the origin of the mass. The defect was closed primarily after the cauterization. The patient is now followed up regularly without any recurrence of the disease.

낭만주의의 한 맥락 - 박범신 문학론 -

정은경 ( Jung Eun-kyoung ) 현대문학이론학회 2016 現代文學理論硏究 Vol.0 No.67

이 글은 박범신 단편소설을 중심으로 박범신 문학이 지닌 낭만주의의 특성에 대해 살펴보았다. 첫째 박범신 문학은 반계몽주의에 바탕하고 있으며 그것은 한국근대문학탄생 이후 작가를 `문사`로 호명하던 지사적 주체에서 벗어난 것으로 해방 이후 대중문화 창작자로서의 작가 존재론의 한 양태를 보여준다. 둘째 70년대 박범신 단편들은 사회현실에 주목한다는 점에서 리얼리즘적이지만 비관주의, 패배주의적 성격이 짙고, 때론 자연주의적 세계관으로 환멸적 세계를 강조하고 있으며, 이성보다는 감성적 태도가 강하다는 측면에서 환멸적 낭만주의로 규정할 수 있다. 셋째, 박범신의 환멸적 낭만주의는 숱한 유년시절부터 형성된 불화의식, 즉 현실과 이상의 간극, 악에 대한 인식으로부터 비롯된 것이고 이는 `악과 죽음` 등에 대한 두려움과 열망이라는 양가적 태도로 드러난다. 넷째 박범신의 죽음충동과 대중 외면에 대한 죄책감은 그를 절필이라는 극단적 선택으로 이끌지만, 사멸해가는 몸짓으로라도 지속되는 글쓰기, 그 지속적인 운동만이 그에게 구원이고, 또한 독자들에게 삼계화택의 가상세계를 열어주는 소중한 작업임을 깨닫고 다시 집필을 하게 된다. 또한 `로망`이 대중적 설화에서 기원했다는 데에서 알 수 있듯, 박범신의 낭만주의는 고립된 환상의 세계라기보다는 세상과 통하고 대중의 욕망을 반영하고 있다는 측면에서 대중성을 함축하고 있다. This essay explored elements of romanticism in Park Bum-shin `s literature focusing on short stories. First, Park Bum-shin`s literature is based on anti-Enlightenment, and it is different from the branch that called the writer as a "pioneer" or a "leader" after the birth of modern Korean literature. Park shows an aspect of the artist`s ontology as a creator of popular culture after liberation. Secondly, Park Bum-shin short stories in the 1970s show disillusioned romanticism. They focused on social reality, emphasizing the disillusioned world with realistic, pessimistic, defeatist, and a sometimes naturalistic world view. Third, Park`s disillusioned romanticism derives from the discord sense that have been formed since childhood, that is, the gap between reality and evil which is revealed by the ambivalent attitude of fear and desire for evil and death. Fourth, Park gave up writing owing to death drive and guilt. But he realize that continuous writing is his salvation and valuable work. As can be seen from the fact that `Roman` originated from the popular narrative, Park`s romanticism implies popularity in the sense that it reflects the desire of the world and communicates with the world rather than an isolated fantasy world.
