참외는 유용한 농업생명자원이면서, 생약 및 한약으로 활용할 수 있는 아주 유용한 자원이다. 참외의 생약명(Medicinal name)은 Melonis Pedicellus이며, Cucurbitaceae에 속하는 Cucumis melo Linné의 초본 꽃받침으로 한약재로 널리 사용되고 있다. 본 연구에서는 Melonis Pedicellus의 한약 특성을 조사하고 Melonis Pedicellus를 함유 한 34개의 한약 포뮬러를 검토하였다. 이 연구는 꼭지 소재 기반 한약재에 대한 추가 연구를 바탕으로 미활용 한약재의 가치를 제고할 수 있다고 사료된다. 먼저 각 국가의 공정서 및 고문헌 분석을 통해 과체 한약재의 기원을 비교하였다. 특히 중국, 일본, 대만이 아닌 남북한의 약전에서 특이점을 찾아볼 수 있었다. 둘째, Melonis Pedicellus에서 발견된 성분을 조사하였다. 지방산 화합물이 가장 많았으며 셋째로는, Melonis Pedicellus 의 생약학적 관점으로 요약하였다. 그것은 구토 성질이 매우 강하기 때문에 구토 요법에 특별히 사용되어 온 사실을 검증하였다. 끝으로 3세기부터 20세기까지의 31편의 고문을 분석하였고, Melonis Pedicellus를 포함하는 34개의 한약재 포뮬러가 문헌에서 발견되었다. Melonis Pedicellus는 주로 구토 요법에 사용되었기 때문에 대부분의 한약 제제가 구토 요법에 상관성 있게 한약재의 본질이 그 공식에 정확히 반영되었음을 의미한다. 이 연구는 Cucumis melo Linné의 꽃받침이 한약재로 사용되어온 근거를 마련했다. Melonis Pedicellus의 기원은 대부분의 동아시아 국가에서 언급되지 않기 때문에 더 확대하여 조사 범위를 넓혀서 연구할 필요가 있다. 본 연구는 한국한의학연구원 제공 전통의학정보포털(KIOM Oasis Portal)과 전북대학교 한국과학문명학연구소에서 제공하는 고의서 빅데이터를 활용하여 고문헌 정보를 효율적으로 확보하였다. 앞으로 과체(瓜蔕)뿐만이 아니라 감꼭지, 연밥 꼭지, 가지 꼭지 등 다양한 식물들의 꼭지를 연구한다면, 무심코 버릴 수 있는 소재에서 현대적 가치를 발견할 수 있는 좋은 소재가 될 것으로 사료된다.

This thesis examines the perception of the plague in the traditional era, the literary response method, the educational meaning of the present day, and the utilizing method of Chinese literature curriculum. Today, while plagues are recognized in terms of overcoming, in the traditional era, plagues are recognized in terms of fear. In the traditional era, plagues were regarded as unclear objects, and literary works were created in a way to cope with plagues. These writings were also created to intimidate and drive out yeoggwi(疫鬼), and were also created to persuade and soothe them away. However, these writings themselves show a high level of literary character. Like today's so-called literary therapy, it goes to the point of healing at the mental and psychological level through the act of literary creation. The literary character of Lee, jeong-gwi(李廷龜)'s funeral oration is a transformation of Han, yu(韓愈)'s Songgungmun(送窮文) and expanding his worries about the country through self-examination. Yu, mong-in(柳夢寅)'s funeral oration describes the tragedy of suffering human beings realistically, is bitter and concrete in criticizing the wrongdoings of yeoggwi(疫鬼). Through such criticism and intimidation, the reversal that was perceived as the object of fear changes into a weak entity, which acts as a mechanism to find and overcome psychological comfort in the pain of reality. The educational meaning and the plan to utilizing Chinese literature curriculum of the two works are as follows. The students can read the wisdom and thoughts of the ancestors who tried to overcome pain through introspection. In addition, students can comprehensively understand byeonmun(騈文), can explain the relationship between Chinese classics and Korean classics. The students can understand the traditional culture's funeral ritual to cope with plagues, and can read the format of the funeral oration, the subject and the content in multiple layers.

Child education (xiaoxue, 小學) literature of the original manuscript of Yupian quoted includes approximately eleven kinds, and the quotation of the literature is about 2,936 times. What is found, in comparison with the standing version of child education literature, is that there are many lexical and expressional relations worth examining and distinguishing in the original manuscript of Yupian quoted, which includes those of characters of the borrowing, the misused, the variant form, the mutual usage, and so on. The value of research into the words and expressions in child education literature of the original manuscript of Yupian quoted is in fact inestimable especially in terms of philology, lexicology, and literary studies. Not only can it explain the abovementioned relations but calibrate the variant forms, folk characters, and semantic errors in dictionary entries. Moreover, it can supplement the errors in omission, and also offer some materials of differentiation between the original manuscript of Yupian and the standing version of child education literature.

Worldwide, oral cancer accounts for 2%–4% of all cancer cases. It is estimated that more of 90% of all oral neoplasms are oral squamous cell carcinoma (OSCC). The aims of this study were to evaluate follow-up outcomes in patients with OSCC invading the mandibular body bone who underwent primary radical resection and reconstructive surgery by fibular free flap or CAD-CAM T-mesh with pathological study on two cases. In this article, two cases of mandibular reconstruction in patients with OSCC invading the mandibular body bone are reported. A 68-year-old male patient visited the authors’ clinic with pain on the left mandibular region. After wide excision and segmental mandibulectomy on the mandibular OSCC, a enterocutaneous fibular free flap from right leg was used to cover the intraoral mucosal defect. The other 51-year-old female patient visited the authors’ clinic with pain on the right mandibular region. After wide excision and segmental mandibulectomy on the mandibular OSCC, reconstruction was done with a reconstruction plate and a fibula free flap from right leg. Unfortunately, fibular free flap was lost due to infection of the flap at post-operative 1month, secondary reconstruction using a custom-made type T-mesh and iliac PCBM was done to repair on the mandibular defect after four years postoperatively. The customized CAD-CAM T-mesh was made prior to the operation according to mirror image of remained jaw. Patients with OSCC invading the mandibular body bone are required an accurate segmental mandibulectomy immediate reconstructive surgery with various methods and followed by adjuvant radiation with or without chemotherapy in order to improve the quality of life through the restoration of the oral function and esthetics after surgery. Postoperative CCRT was determined according to the final pathologic findings such as lymph node metastasis and main lesion free margin safety, and this has an essential relationship in the prognosis of postoperative recurrence. We reviewed reliable treatment options on two patients of OSCC in mandible with pathologic findings.Worldwide, oral cancer accounts for 2%–4% of all cancer cases.

본 논문의 목적은 상감문학에 나타난 무루간의 형상화 양상을 통시적으로 고찰하는 것이다. 무루간은 전쟁과 승리의 신이자 따밀나두를 상징하는 신이다. 그에 대한 따밀문학의 가장 오래된 기록은 상감 시대에 저작된 상감문학에서 찾을 수 있다. 초기 상감 시에서 그는 꾸린지 산의 주인이자 악한 자를 벌하는 무시무시한 신, 처녀에게 사랑의 고통을 주는 신으로 그려진다. 무루간의 분노를 달래기 위해 행해지는 베리얏땀 의식은 결혼하지 않은 연인의 비밀스러운 사랑의 감정을 극적으로 보여주기 위한 시적 장치로 기능한다. 북인도를 대표하는 산스끄리뜨 문화와 남인도를 대표하는 따밀 문화가 만나면서 상감문학에 나타난 무루간의 형상화 양상에도 변화가 생겼다. 초기 상감 시에 나타난 무루간 의 이미지에 신화적 요소가 더해지기 시작했고, 그는 신성 군대의 사령관이 되었다. 이와 함께 무루간 숭배는 새로운 질서를 세우며 체계적으로 발전하게 되었고, 무루간은 보편적인 신이 되어 세상에 편재하게 된다. 상감문학에 나타난 무루간의 형상화 양상의 변화는 이후 따밀문학사에 등장하는 박띠문학의 태동을 알리는 암시가 된다.

근대 영어와 영문학에 기여한 대표적인 요인으로 교육혁명과 윌리엄 틴데일의 성경 번역을 들 수 있다. 인본주의와 실용성에 근거한 에라스뮈스의 수사학 이론과 번역된 고전들은 많은 영국 작가들을 위한 토양이 되었다. 이와 같은 환 경에서 교육받은 틴데일은 성경은 모국어로 읽어야 한다는 신학적 동기를 가지고 그의 역서에서 원어의 성경적 의미는 놓치지 않으면서 간결하고도 웅장한 구사를 할 수 있었다. 틴데일 성경에 사용된 다양한 새로운 단어들, 관용구들, 그리고 수사적 장치들은 16세기의 언어적이고 문학적인 발전에 지대한 영향을 미쳤다. 틴데일이 없었다면 엘리자베스 시대와 그 이후에 나타난 직설적인 산문체는 물론이고, 셰익스피어를 비롯한 당대 영국 작가들의 역동적이면서도 간결한 문어체도 없었을 것이다.

Leiomyoma is a Benign tumor that develops in smooth muscles and is known to occur more in women in age between 40s and 50s. The most common site of leiomyoma is uterine (95 %). It occurred in oral region is very rare about 0.065 % and usually developed in upper and lower lips, palatal site, buccal site and tongues. The prognosis of leiomyoma is very positive. The recurrence rate is extremely low to 2 % below. In present study, we report a 78 year old female with a lesion located in temporomandibular joint cavity which was suspected as a malignant tumor. Additionally, this paper reports contains a literature review of oral leiomyoma. Rare location with painless leiomyoma of present case will be considered to be caution.

While efforts have been made to address fall-related injuries in older adults, the problem is unsolved to date. The purpose of this review is to provide a guideline for fall and injury prevention programs in older adults, based on evidence generated over the past 30 years. Research articles published between 1990 and 2020 have been searched on PubMed, using keywords, including but not limited to, falls, hip fracture, injuries, intervention, older adults, prevention, hip protector, vitamin D, safe landing strategy, and exercise. Total of 98 articles have been found and categorized into five intervention areas: exercise program, hip protector, safe landing strategy, vitamin D intake, and compliant flooring. Furthermore, the articles have been rated based on their study design: class 1, randomized controlled trials; class 2, nonrandomized controlled trials; class 3, experimental studies; class 4, all other studies. Exercise programs have shown to decrease the risk of fall, and associated injuries. Hip protectors, safe landing strategy, and vitamin D intake were effective in reducing a risk and incidence of hip fracture during a fall. Furthermore, compliant flooring has also decreased hip fracture risk without affecting balance. An integrated approach combining exercise program, wearing a hip protector, teaching safe landing strategies, scheduled vitamin D intake, and compliant flooring installation, is suggested to address fall-related injuries in older adults.

이 글은 경미문학의 근원이라 인정되는 라오서(老舍)와 신경미(新京味) 작가 왕쑤 오(王朔)를 통해 20세기 베이징 도시문화의 함의와 그 변화의 일면을 살핀다. 라오서는 후통(胡同), 스허위엔(四合院)을 통해 보수적인 라오베이징 시민들을 섬세하게 그려냈다. 그는 찬탄과 그리움뿐만 아니라 냉정한 통찰과 비판의 시선을 베이징의 민속문화를 바라본다. 반면 왕쑤오의 베이징 기억과 상상은 온통 따위엔과 사회주의 혁명문화에 집중되어 있다. 따위엔은 혁명문화의 표상체인 동시에 진원지였다. 1950년대부터 지금까지 베이징 문화의 주류는 따위엔 문화다. 1949년을 경계로 베이징은 전통문화가 각인된 스허위엔·후통 문화에서 사회주의 혁명문화를 중심으로 하는 따위엔 문화로 전환되었고 그 영향력은 지금도 막강하다. 1940년대의 라오서와 신중국 건립 이후의 왕쑤오를 통해 도시와 개인 정체성의 문제를 탐색하는 작업은, 도시 주요 거주공간의 변화에 대한 탐문인 동시에 제국도시 베이징에서 사회주의 수도 베이징으로 변모해가는 양상을 살피는 작업이다.

생전예수재는 조선시대 수륙재와 함께 활발하게 설행되었던 불교의식 이다. 수륙재가 죽은 자의 안락을 위한 의식이었다면, 생전예수재는 산 자가 살아있는 동안 자신의 삶을 경계하고 죽은 후의 영원한 안락을 누 리기 위한 의식이자 신앙이었다. 때문에 생전예수재는 낮에 설행되었고, 수륙재는 밤에 설행되었다. 조선시대 생전예수재의 직접적인 명칭은 나 암 보우가 찬술한 글에서 처음 발견된다. 예수재는 왕과 왕실, 조상, 그리고 스승과 자신의 평안을 위해 설행되었다. 조선시대 불교가 탄압받고 소외받은 것은 널리 알려진 사실이다. 그 럼에도 불구하고 불교의식과 신앙은 단절되지 않고 그 전통을 계승하고 있었다. 특히 조선후기는 두 차례의 전쟁과 자연재해로 전염병과 굶주 림이 일어났다. 결국 많은 사상자가 발생했고 그들을 추모하고 안락을 기원하는 불교의식이 설행되었다. 조선의 불교전통이 단절되지 않고 계승될 수 있었던 이유였다.

현대는 스마트폰이나 태블릿PC, 전용 단말기로 전자책을 읽을 수 있는 시대이다. 최첨단 시대일수록 네트워크에 기반을 둔 정보의 공유와 보존이 바탕을 이루는 디지 털화가 이루어져 있다. 즉 디지털화는 ‘정보의 공유와 보존’으로부터 나와야 하며 효 율적인 ‘공유와 소통’을 위한 작업이 이루어져야 한다. 이런 의미에서 세계 한자학자 들의 연구문헌 DB 구축은 종이라는 2차원적 정보매체를 세계 모든 사람에게 어디서 나 제공할 수 있는 3차원의 정보로 바꾸는 것으로 DB 속에 있는 다양한 정보를 공 유하고 소통할 수 있게 하는 작업이다. 그래서 본 연구에서 구축하고자 하는 세계 한자학자 연구문헌 DB는 현 시대에서 무엇보다 필요한 것이다. 구축된 세계 한자학 자 연구문헌 DB는 한자학사와 중국학, 언어학사 등의 넓은 영역에서 정확하고 통합적인 학술적 기초자료를 마련함으로써 앞으로 학계의 심화 연구 발전에 큰 역할을 하게 될 것이라 기대된다.

The topics addressed, scope, and approach of this paper involve contemporary postmodern/poststructural critical theory, literary criticism in particular, and Mahayana (大乘)—especially kongan (公案) and hwadu (話頭) Ch’an(Chinese)/Seon(Korean)/Zen (Japanese)—Buddhist thought (佛敎思想) is explained in detail. However, the theoretical ground is only to help the twenty-first century audience to deeply comprehend how literature and film offer us precious opportunity to experience the sublime (崇古)—aesthetic sensibility (美的感覺), through which we glimpse (一見) the ultimate reality (窮極的 現實). It is time now that intellectual (philosophical, critical, academic) explanation and spiritual experience are brought to work together in the common area, literature (文學) and film (映畫). It is important for literary readers to experience someone’s life story in the way of encountering the non-duality (非二重性) of the ultimate reality.

Systematic literature reviews (SLR) are very important to track the extent to which studies related to the formulation of Halal Catering on board have been previously studied by previous scholars. Therefore, the SLR study requires a clear and detailed understanding concerning the study direction for each selected article by analyzing the scope of the study and its dimensions as the main emphasis whether it has been discussed by any previous scholar or otherwise. Through the basis of the analysis of literature reviews will enable the specific detection of the title of the study. Even SLR analysis is also able to compare in terms of the year the article was published by comparing the differences in scope and dimensions of each article by selected scholars referred to 16 scholars from the year 2012 until 2017. Regards to methodology, SLR emphasised into five stages such as i) Time Frame, ii) Selection of a database, iii) Journal selection, iv) Article selection and v) Literature review analysis. Analysis, discussion, and findings will be focusing on the scope, dimensions, and years of studies by using figures, tables as facilitators of analysis and findings. Hence, the role of Halal institutions will be able to assess its ability to form halal rules with the involvement of stakeholders and the scope that has been affected in detail.

It is at present generally believed that there was only 疾 but not 病 in the disease-related oracle bone inscriptions. This implies that there was no distinction between the two characters in the late Shang Dynasty, and that their concepts were not thoroughly understood in the Yin and Shang dynasties either. It was not until the middle of the Warring States period that the word 病 began to gradually replace the word 疾. In the early years of the Western Han Dynasty, the word 病 had a slight advantage. Since the Eastern Han Dynasty, the meanings of 疾病 (disease) and 生病 (to catch a disease) have been basically used instead of 疾. However, from the oracle bone inscriptions, there are about two kinds of characters: 、 and . These different types of hieroglyphs indicate different situations. The word 疾 in oracle bone inscriptions has not merely different glyphs but different concepts of human diseases as well. Therefore, this paper intends to trace back to the concept and usage of 疾 and 病 in the late Shang Dynasty from the shape of the word 疾 in oracle bone inscriptions, and to the evolution of the meanings of 疾 and 病 in ancient literature.

Many studies utilizing dogs, cats, birds, fish, and robotic simulations of animals have tried to ascertain the health benefits of pet ownership. some research has associated viewing fish in aquariums with positive well-being outcomes; as there is no physical contact with the animal, this form of interaction carries less risk. From the points mentioned above it is clear that having an aquarium can significantly influence life and health. Aquariums can heal a stressed out body and mind making it clear of all unwanted thoughts which reduces the stress and blood pressure. Watching beautiful fishes swim in the aquarium provides a break to the viewer from all the routine work in life and cause a sense of relaxation or calmness. It helps kids to gain knowledge about a variety of fishes and learn how to care for them. Hyperactive kids become quiet and calm. These positive effects on health are caused due to secretion of neurochemicals influenced by gazing at colorful active fishes swimming in the tank. The remaining studies involved novel interactions with fish in home or public aquariums. Outcomes relating to anxiety, relaxation and/or physiological stress were commonly assessed; evidence was mixed with both positive and null findings. Preliminary support was found for effects on mood, pain, nutritional intake and body weight, but not loneliness. All studies had methodological issues and risk of bias was either high or unclear. Review findings suggest that interacting with fish in aquariums has the potential to benefit human well-being.

Purpose: Recently, with the increasing demand for a evidence-based practice model in the health care area, qualitative meta-synthesis studies that provide a comprehensive understanding of phenomena of interest has increased. This study was conducted to understand the concept of qualitative meta-synthesis and guide the application of appropriate methods. Methods: This study is a literature review to address and analyze concepts and methods used in qualitative meta-synthesis studies. Results: The definition and purpose of qualitative meta-synthesis, philosophical background, procedures and outcomes are described. And the meta-ethnography, which is widely applied, was described. In addition, grounded theory, critical interactive synthesis, and meta-study were briefly introduced. It is also desirable to evaluate the quality of the primary research paper by utilizing evaluation criteria and evaluation tools to select the primary research paper, which also affects the quality of qualitative meta-synthetic studies. It is necessary for the researcher to recognize the epistemological difference in qualitative meta-synthesis, to consider saturation of the primary research paper, and to minimize the decontextualization of the primary research paper. Above all, the creative interpretation of researchers should provide expanded knowledge and insights into the research area. Conclusion: By clarifying the purpose of qualitative meta-synthesis, the researcher should ensure justification for performing qualitative meta-synthesis. Researchers also need to make efforts to ensure methodological transparency in order to overcoming the limitations of qualitative meta-synthesis.

Odontogenic keratocyst (OKC), also known as keratocystic odontogenic tumor, is a distinct clinicopathologic lesion that can be clearly identified by histologic examination. Clinically, OKC is characterized by a high recurrence rate. This report describes a rare case of OKC with mural calcification in the maxilla of a 47-year-old male patient. Orthopantomography and Cone Beam Computed Tomography showed full opacification with calcification and lateral wall resorption in the left maxillary sinus, destroying the sinus floor. Hard tissue deposits have rarely been reported in the connective tissue walls of OKC. The importance of calcified material formation to the biological behavior of OKCs is unclear. Although its prognostic value has not been studied, the presence of calcification materials does not appear to increase the risk of recurrence. Study of a number of samples would be needed to determine the nature of the correlation between the presence of calcified materials and recurrence.
