Primary intraosseous squamous cell carcinoma is a rare malignant central jaw tumor derived from odontogenic epithelial remnants. Predominantly, it affects mandible, although both jaw bones may be involved. This report describes a 60-year-old man who was initially misdiagnosed with a periapical infection related to the right lower wisdom tooth. After four months, the patient presented to a private dental clinic with a massive swelling at the right side of the mandible. Panoramic radiographs and advanced imaging revealed a lesion with complete erosion of the right ramus, which extended to the orbital floor. A biopsy from the mandibular angle revealed large pleomorphic atypical squamous cells, which is the primary microscopic feature of a poorly differentiated squamous cell carcinoma.

Cellulase is the key enzyme in the use of cellulose-based biomaterials. Because of its structure, cellulose is difficult to be degraded by enzymes. In order to utilize cellulose-based biomaterials efficiently, evolutionary wisdom of how to use enzymes accurately and harmoniously in a biological system is needed, such as the cellulose digestive system in animals. In this study, the symbiotic bacteria from snails, Achatina fulica, were identified and their cellulase activity was evaluated. The 16S rRNA sequence analysis of 100 aerobic bacteria showed that they belonged to 9 genus and almost half of the bacteria were Lactococcus spp. Among 100 identified strains, only two Aeromonas sp. strains showed cellulase activity. Aeromonas sp. KMBS020 had both endo-${\beta}$-glucanase and ${\beta}$-glucosidase activities but Aeromonas sp. KMBS018 had ${\beta}$-glucosidase activity only. None of the 100 bacterial colonies had any cellobiohydrolase activity.

One of the historical origins of the modern science education was investigated in this paper. From the view point of the pansophistic educational philosophy which emphasized "man should teach completely all things to all mankind(Omnes, Omnia, omnino)", J.A.Comenius proposed in his book "Didactica magna"(1658) that 'physica' should be learned as one of the most important school subjects. He suggested the completion of human being as a wholeness of the universe could be achieved through the physics teaching. His ideas of science education was, however, directed not to the 'rational konwledge' about the natural world, but to the 'divine wisdom'. His main thoughts and influences on science education can be summarized as follows: 1) The human being as a God's image should know the divinely created nature, because the invisible God's existence can be sensorially recognized in the nature. 2) Physics or science should be regarded as more important objects than verbal learning in general school education. 3) The cognitive union between the words('representative' or 'das Dargestellte') and things('presentative' or 'das Dargebotene') can be achieved through the objects lesson ('Anschauungsunterricht') 4) The realistic and sensor-cognitive learning theory of the object lesson is yet very important especially in the science education of elementary school, even though the inquiry learning process has became more important in the last years. 5) The religious aspect of his idea could not satisfy the social needs of industrialization and the development of professonal technics in the 18 to 19th century.

This Paper aims to elaborate on the origin of thinking mind. And this is a cooperative project between philosophy and neuroscience and brain science. I have written this paper in admiration for the achievements of twentieth century neuroscience and brain science, and out of desire to assist the subject in future. Much of the history of modern philosophy, from Descartes and Kant forward, consists of failed models of brain. As Edward O. Wilson precisely said, the shortcoming is not the fault of the philosophers, who have doggedly pushed their methods to the limit, but a straightforward consequence of the biological evolution of the brain. Guiding that investigation down pathways that will illuminate brain research is a task of neuroscience and brain science. Investigating logical relations among concepts is a philosophical task. If we are to understand the neural structures and dynamics that make perception, thought, intentional behaviour possible, clarity about these concepts and categories and their relations is essential. Hence our joint venture of philosophy and science. Sure, it is human beings that perceives, not parts of its brain. And it is human beings that who think and reason, not their brain. But the brain and its activities make it possible for human beings-not for it-to perceive and think, to feel emotions, and to form and pursue projects. Thus We try to investigate and reveal the origin of thinking mind as follow: 1) The difference between chimpanzee and human beings 2) brain and mind 3) the origin of thinking 4) the wisdom of nature.

The origines of the Western roasting culture and East Asian boiling culture were studied and the importance of primitive pottery culture (8000-5000 BCE) in the Korea Strait coastal region was discussed. The primitive pottery culture probably initiated the Jjigae (stew) culture and the production of salt. It can be also postulated that fish fermentation, kimchi fermentation, and cereal alcohol fermentation originated during this period. Soybean culture emerged ca. 2,000 BCE in South Manchuria and the Korean Peninsula. This paper focuses on the role of Korean foodways in the food science and technology development for the sustainable and resilient food systems. We are facing a global food crisis caused by population growth, climate change, and high animal food consumption. Studies on the meat analog and cultured meat are the new trend in Food Science and Technology. The importance of the wisdom learned through the Northeast Asian traditional foods, for example, soybean curd (tofu) and meaty flavor production by fermentation for the research on the novel sustainable and resilient food systems are discussed.

Traditional wisdom on how late industrialized countries follow the technology trajectories of preceding economies is in need of reformation as these countries have attained industrial leadership in a growing number of fields. However, current understandings about these countries' development of their emerging technologies have yet to investigate the divergence of idiosyncratic technology trajectories. The aim of this paper was to explore how their knowledge production strategies in emerging technology sectors are diverging. Specifically, this research examines the changing patterns of knowledge production in quantum technology in South Korea and China by developing a knowledge portfolio and knowledge strategic diagram. According to the knowledge portfolio, the relative literature position differs. In the knowledge strategic diagram, there are diverging patterns in the emerging keywords sector. This paper contributes to the literature by demonstrating the diverging strategies of late industrialized countries in their transition from catch-up to post-catch-up paradigms and provides policy implications for countries developing an idiosyncratic trajectory in emerging technology sectors.

This study was designed to investigate the nature and magnitude of disability among non-institutionalized elderly in urban area(Seoul city). From November 1987, through December 1987, 1,054 individuals aged over 65 years from the sampled of clustered random sampling method were interviewed in person. The physical disability findings support the well known relationship between physical disability and age. The magnitude of disability, however, is not as great as conventional wisdom might suggest. And this paper reports results on the prevalence of social disability : housekeeping transportation, food prepatation, grocery shopping, social interaction, intellectual activity, and social role. The magnitude of social disability increase with advancing age. Women, in general, report a higher degree of social disability than man. These findings are compared with other investigations of physical and social disability among the elderly.

본 논문에서는 한국어 단어를 산출하는 과정에서 음절 내 부호화 과정을 규명하기 위해 2개의 단어번역과제 실험을 수행하였다. 한국어 산출에서 종성점화효과를 검증한 실험 1에서 종성 반복 조건과 통제조건 간에 단어번역시간에서 차이를 보이지 않았다. 반면에 실험 2에서는 11ms의 부적인 중성점화효과를 보였다. 구민모와 남기춘(2009)과 본 연구의 결과를 종합하면, 다음과 같은 결론에 도달한다: (1) 한국어 산출 어휘집에서 음절은 "음절체+종성"의 위계적인 내적 구조로 표상된다. (2) 음절 내 부호화는 음절체와 종성이 계열적인 순서로 진행된다. (3) 음절체를 구성하는 초성과 중성이 계열적인 순서로 음절구조에 삽입된다.
