Cemento-ossifying fibroma is a benign fibrous lesion with an unknown cause, mostly asymptomatic, painless swelling of the affected jaw. This is a case report on a cystic lesion found on radiographic examination in a patient with an extraction of mandibular left tooth. A 29-year-old female was referred to Pusan National University Dental Hospital due to a radiopaque lesion in the left mandible. On the medical history examination, the left lower mandibular tooth had been extracted 4 years ago, and there were no specific findings in the general medical history. According to histopathologic findings, along with proliferation of spindle cells, cementum-like substances were observed along with irregularly shaped osseous calcified substances containing osteocytes in the cellular fibrous connective tissue. In this study, we report a case that showed cystic changes due to tooth extraction, which made it complicated to determine the differential diagnosis from the existing fibrous-osseous lesion.

Dentigerous cyst is considered one of the representative cystic lesions, which accounts for approximately 15%-30% of the odontogenic cysts. Although its recurrence rate is low, a small proportion of dentigerous cysts converted into ameloblastomas, squamous cell carcinomas, and mucoepidermoid carcinomas. Here we present an uncommon case characterized by histopathological transformation from a dentigerous cyst to an ameloblastoma, and further investigate the factors contributing to its conversion.

This study aims to review observational methods for assessing postural loads such as OWAS, RULA and REBA, and to compare them, based on the literature survey. The literature was searched through academic database of ScienceDirect using the key words of observational methods, OWAS, RULA and REBA. The results exhibited that of the thee methods, RULA was cited in the literature and applied to manufacturing industries the most frequently. Although it has been known that RULA is appropriate for assessing upper body postures, it has been applied to healthcare and social work activities, agriculture, forestry, fishing, construction, mining and quarrying, which require unstable lower limb postures. The countries where more number of relevant studies have been carried out were USA, India, Brazil, UK, etc. It was recommended that of the three techniques, RULA may be better for assessing postural loads, because it evaluated postural loads more highly, irrespective of industry, work type and lower limb postures, and its assessment results had higher agreement rate with experts’ assessments than those of OWAS and REBA. It is expected that the results of this study will be used as a guideline for selecting an appropriate observational method.

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.

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.

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.

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.

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.

With few reported cases, cystic hygroma is known to occur mainly in patients under the age of two years. Cystic hygroma can eventuate in any area; however, it mostly occurs in the cervicofacial area. If cystic hygroma occurs in this area, then the lesion may be related to the vital structures. Therefore, a complete surgical resection may be impossible and difficult to perform. This incident affects the high recurrence rate of cystic hygroma. The purpose of this report is to present a case of cystic hygroma occurring on the left side of the neck of a 47-year-old male patient as well as a review of literatures.

Photodynamic therapy (PDT) has been widely used in clinical fields and done by three components: photosensitizers (PSs), light and oxygen. Under the action of PS as an energy transforming media, the light energy is converted to chemical energy to make effects on target. In the process of PDT, its effect is determined a lot by the parameter of light and the characteristics of PSs. With the development of light source and photosensitizer, the application of PDT has been investigated in oral diseases. This review mainly focused on the effect of PDT on non-tumor diseases of oral cavity, including endodontic, periodontal and mucosal problem. Compared with the normal therapy, the combination therapy with PDT could obtain better efficacy. It was suggested that PDT showed great advantages as an adjuvant therapy in the above oral diseases. Through a further improvement, PDT is expected to play an increasingly important role on the oral disease treatment in the future.

Purpose: Despite the effort to bridge the disconnect between educational preparation of competent nurses and employers' expectation of new graduates, there is little known about what nursing competencies are required for new graduates. This paper aims to identify the nursing competencies expected of new graduates, both globally and in the specific Korean context. Methods: An integrative literature review was undertaken. International and Korean computerised databases were searched and 72 relevant papers were appraised using the Mixed Methods Appraisal Tool and the Data Relevance. Twenty-eight studies were selected for final data analysis. Results: Three themes with eleven competency areas were discovered: new graduates are expected to be competent in delivering an evidence-based practice with a patient-centered approach as professional nurses. Competency in evidence-based practice involves being able to integrate theory and skills, utilise contemporary evidence, and undertake a systematic approach. Patient-centred care involves ensuring patient safety, educating the patient and their family, and demonstrating sound interpersonal communication skills with a collaborative approach. New graduates are also expected to practice legal and ethical nursing care, undertake continuing professional development, and demonstrate a capacity for clinical management and appropriate professional attributes. Conclusion: Identifying nursing competencies for new graduates can add a level of detail to the current nursing competencies required for new graduates in the global and the Korean context. The findings can be used not only to inform education providers of potential gaps in preparation for practice of new graduates, but also be used to identify support needed when graduates enter nursing workforce.

Anecdotal reports indicate that maladaptive patterns of Internet use constitute behavioral addiction. Internet addiction is characterized by unrestrained and awfully controlled engrossment or behaviors regarding internet access that lead to impairment, stress, dimensionally measured depression, indicators of social separation and anguish. By reviewing and analyzing approximately 100 articles we present evidence that are able to provide an overview of the main themes and proclivity covered by existing and relevant studies. The vital detection of this research unveils that many factors related to social, demographic, lifestyle changes related constructs have a bearing on the phenomenon of internet addiction strongly. This study not only reached certain conclusions for both theory and practice, but also defined future lines of research according to the gaps detected by the study’s results. The main findings from this literature, though not conclusive, but will help the researcher and policymakers to obtain a better understanding and description of the problem faced by the youth and necessary to develop some remedies to lessen the addiction phenomenon.

마사 C. 누스바움(Martha C. Nusbaum)은『정치적 감정』(Political Emotions) 에서 공적 자산으로서 정치적 감정의 중요성을 다루고 있다. 누스바움은 연민과 공감이라는 인간 이해의 감정이 배제된 신자유주의 사회의 문제점을 제기하며, 바람직한 사회로의 변혁을 위해 문학을 포함한 예술적 상상력을 통한 사랑의 감정 소환을 주장한다. 그녀의 정치·철학의 바탕이 되는 주제어인 정의, 사랑, 정치적 감정은 ‘e pluribus unum’으로 표상된다. ‘e pluribus unum’은 ‘여럿이 모여 하나’라는 뜻으로, ‘품위 있는 사회’로의 발전을 위한 정치적 대안으로 나타난다. 누스바움은 보편적 인간의 사랑이라는 공적 감정을 강조하면서도 종교의 역할을 의식적으로 배제한다. 그녀가 제안하는 온전한 정의로운 사회는 인간 중심의 세속적 사회에 한정된다. 그러나 존재에 대한 궁극적 관심과 우주의 시원적 세계에 관심을 가지는 인간을 배제한 품위 있는 사회는 온전하다고 보기 어렵다. 문학과 예술적 상상력의 사랑에 편중하고 종교적 상상력의 사랑을 배제한 누스바움의 정치철학은 인간 감정과 삶의 조건을 단순화시켰다는 한계를 보인다.

This study aims to investigate the food preservation methods adopted by the Joseon Dynasty, which existed before the 17th century. A total of 232 food preservation methods were discovered in 25 books, and could be classified by their targeted food types: vegetables (84), sea foods (60), meats (41), fruits (37), and others (10). Depending on the preservation method applied, they are classified as food drying, soaking, mud cellar preservation, and other preservation. Food drying is further classified into 8 sub-types: drying, sun-drying, shadow-drying, wind-drying, dry heat, combined drying, smoking, and others. Soaking could be sub-divided into using salt, ash, dry sand, bran, fermented paste, wet distillers grains, oil, and others. Mud cellar preservation is sub-classified into installing shelf inside the mud cellar, making the mud cellar for food preservation, and making hole or underground tunnel for food preservation. Other food preservation methods include minimizing moisture loss by applying beeswax on a section of the vegetable stem, and cutting the vegetables or fruits with their branches and leaves for food preservation.
