  • This paper aims to evaluate works of Frege and G$\ddot{o}$del, who play the trigger role in development of logic, by Knowledge Change Model. It identifies where their positions are in the model respectively. For this purpose I suggest types of knowledge change and their criteria for the evaluation. Knowledge change are classified into five types according to the degree of its change: improvement, weak glorious revolution, glorious revolution, strong glorious revolution, and total revolution. Criteria to evaluate the change are its contents, influence, pervasive effects, and so forth. The Knowledge Change Model consists of the types and the criteria. I argue that in the model Frege belongs to the total revolution and G$\ddot{o}$del to the weak glorious revolution. If we accept that the revolution in logic initiated by Frege was completed by G$\ddot{o}$del, it is a natural conclusion.

  • Background: Colorectal cancer (CRC) is the third most common cancer globally. In Jordan, it is the number one cancer among men and the second most common cancer among women, accounting for 15% and 9.4% respectively of all male and female diagnosed cancers. This study aimed to evaluate the knowledge and perceptions about colorectal cancer risk factors, signs and symptoms in Jordan and to provide useful data about the best modes of disseminating preventive messages about the disease. Materials and Methods: A stratified clustered random sampling technique was used to recruit 300 males and 300 females aged 30 to 65 years without a previous history of CRC from four governorates in Jordan. A semi-structured questionnaire and face to face interviews were employed. Descriptive and multivariate analysis was applied to assess knowledge and perceptions about CRC. Results: Both males and females perceived their CRC risk to be low. They had low knowledge scores about CRC with no significant gender association (P=0.47). From a maximum knowledge score of 18 points, the median scores of males and females were 4 points (SD=2.346, range 0-13) and 4 points (SD=2.329, range 0-11) respectively. Better knowledge scores were associated with governorate, higher educational level, older age, higher income, having a chronic disease, having a family history of CRC, previously knowing someone who had CRC and their doctor's knowledge about their family history of CRC. Conclusions: There is a low level of knowledge about CRC and underestimation of risk among the study participants. This underlines the need for public health interventions to create awareness about the illness. It also calls for further research to assess the knowledge and perceptions about CRC early detection examinations in Jordan.

  • Background: Breast cancer is the commonest type of cancer among women, and in Malaysia 50-60% of the new cases are being detected at late stages. Do age, education level, income, ethnicity, relationship with breast cancer patients and knowledge of breast cancer risk factors influence breast screening practices? This study revealed interesting but significant differences. Objectives: To assess the knowledge of breast cancer risk factors and early detection measures among women in a high risk group. Materials and Methods: A cross sectional survey of one hundred and thirty one women relatives of breast cancer patients was carried out. Participants were selected through purposive sampling, during hospital visits. A self-administered questionnaire was used for data collection. Results: The majority of the respondents (71%) had poor knowledge of the risk factors for breast cancer. Income, relationship with a patient and practise of breast cancer screening predicted performance of mammography, $R^2$=0.467, F=12.568, p<0.0001. Conclusions: The finding shows inadequate knowledge of breast cancer risk factors and poor cancer screening practise among women with family history of breast cancer. Poor knowledge and practise of breast screening are likely to lead to late stage presentation of breast cancer disease. Some important predictors of breast cancer screening behaviour among women with positive family history of breast cancer were identified. An understanding of the strengths and significance of the association between these factors and breast screening behaviour is vital for developing more targeted breast health promotion.

  • The purpose of this research is to build a database structure that can be useful for evidence-based medical practices by constructing the knowledge related to oriental medicine in the classical literature knowledge in a form that can utilize new forms of information technology. As a method, "database" is used as a keyword to search published studies in the field of oriental medicine, research is conducted on classic literature knowledge, and studies describing the contents of the data structure are found and analyzed. In conclusion, the original text DB for the preservation of the original texts and the presentation of the supporting texts should include 'Contents Text', 'Tree Structure', 'Herbal Structure', 'Medicine Manufacture', and 'Disease Structure' tables. In order to search, calculate, and automatically extract expressions written in the original text of the old literature, the tool DB should include 'Unit List', 'Capacity Notation List', 'CUI', 'LUI', and 'SUI' tables. In addition, In order to manage integrated knowledge such as herbal, medicine, acupuncture, disease, and literature, and to implement a search function such as comparison of similarity of control composition, the knowledge DB must contain 'dose-controlled medicine name', 'dose-controlled medicine composition', 'relational knowledge', 'knowledge structure', and 'computational knowledge' tables.

  • 이 연구는 대학생의 A형 간염 지식, 건강신념, A형 간염 예방접종 행태를 파악하기 위하여 실시하였다. 대구 경북지역의 보건계열을 제외한 4년제 대학생을 대상으로 2014년 3월 3일부터 3월 25일까지 구조화된 설문지를 이용한 자기기입식 설문조사를 하였으며, 총 197부를 최종분석대상으로 하였다. 연구대상자들의 A형 간염 지식점수는 15점 만점에 $4.59{\pm}3.06$점이었으며, 건강신념 점수는 4점 만점에 $2.39{\pm}0.28$점이었고, A형 간염 예방접종률은 12.7%였다. A형 간염 지식은 A형 간염 검사 경험, 가족 중 A형 간염 예방접종 경험에 따라 유의한 차이가 있었고, 건강신념은 성별에 따라 유의한 차이가 있었다. A형 간염 예방접종은 A형 간염 검사 경험, 가족 중 간질환, 가족 중 A형 간염 예방접종 경험, A형 간염 교육 경험 등에 따라 유의한 차이가 있었다. 로지스틱 회귀분석 결과, A형 간염 예방접종 행태에 유의한 영향을 미치는 변수는 A형 간염 검사 경험과 가족 중 A형 간염 예방접종 경험이었다. 결과적으로 연구대상자들의 A형 간염 지식, 건강신념 수준이 낮았으며 A형 간염 예방접종률 또한 낮았다. 따라서 적절한 보건교육을 통해 지식을 습득할 수 있게 하고, 질병 예방행위 실천 및 A형 간염 예방접종률을 높일 수 있는 방안들이 모색될 필요가 있을 것이다.

  • This study is on the theory of Piaget's reflective abstraction and the mechanism of the development of knowledge and the history of algebra and its application to understand the difficulties that many students have in learning algebra. Piaget considers the development of knowledge as a linear process. The stages in the construction of different forms of knowledge are sequential and each stage begins with reorganization. The reorganization consists of the projection onto a higher level from the lower level and the reflection which reconstructs and reorganizes within a lager system that is transferred by profection. Piaget shows that the mechanisms mediating transitions from one historical period to the next are analogous to those mediating the transition from one psychogenetic stage to the next and characterizes the mechanism as the intra, inter, trans sequence. The historical development of algebra is characterized by three periods, which are intra inter, transoperational. The analysis of the history of algebra by the mechanism explains why the difficulties that students have in learning algebra occur and shows that the roles of teachers are important to help students to overcome the difficulties.

  • Unani medicine has been used extensively as preventive and therapeutic healthcare in India. It mostly utilizes herbal drugs for the treatment of various conditions and ailments. It is based upon the humoural and temperament theory of Buqrat (Hippocrates). Unani medicine is one of the oldest traditional system rooted within the Greek, Iranian, Arabic, and Islamic medical knowledge and has developed as a scientific healthcare system. It is highly practiced and popular in certain parts of the world, and the World Heritage Centre, part of the United Nations Educational, Scientific, and Cultural Organization (UNESCO), and the United Nations Foundation list it as an authentic and still-living form of traditional medicine. But in the past, its survival required utmost efforts from different dynasties, scholars and organization around the world. The efforts of promotion, preservation, translation, upgradation and publication of medical knowledge has crucially given new life to Unani medicine in each era. This letter will enlighten the efforts of translations of medical knowledge in Unani medicine from its arising need in the past till present.
