The purpose of this study was to examine the cause of new curriculum which has always problems even though it is revised repeatedly and to propose an fundamental alternatives to solve these problems. In this study, the cause of these problems considered the wrong point grasping the knowledge of curriculum contents. In other words, the knowledge of curriculum contents is understood as the point of utility rather than the curriculum are constructed as the form reflecting nature of knowledge. According to do this, Bruner's structure of knowledge is of help. The structure of knowledge which is well known existing is understood as manifest aspect but from now on, we have to be concerned about tacit aspect. In this case, the structure of knowledge has characteristics as an integrated knowledge.

Threat is one special type of communication whereby one conveys opinion, knowledge, or attitude to another with an intention to influence and modify the latter's opinion or behavior. This research aims at identifying the antecedents and the effectiveness of threats applied in the process of purchasing decision-making. The research model integrates constructs derived from the literature of diverse discipline. The framework suggested explains the relative effects of threats, is tested empirically to verify the impacts on the influenced target's opinions and behaviors in buying centers. Data are collected from CAPM's members in Taiwan, and 208 respondents served as targets in the interpersonal relationships. LISREL findings indicate that threats are effective in winning a target's compliance. Additionally, influencing source's characteristics affect the choice of threats more strongly than target characteristics do. The relative ability of dependence on the source to cause manifest influence is even more significant than that of threats. Overall, the results of this study appear consistent with behavioral theories and research.

This article analyzes mathematics education from dialectical materialism acknowledging the objectivity of knowledge. The thesis that knowledge is objective advances to the recognition that knowledge will be internalized, and an idea of zone of proximal development(ZPD) is established as a practice program of internalization. The lower side of ZPD, i.e. the early stage of internalization takes imitation in a large portion. And in the process of internalization the mediational means play an important role. Hereupon the role of mathematics teacher, the object of imitation, stands out significantly. In this article, treating the contents of study as follows, I make manifest that teaching and learning in mathematics classroom are united dialectically: I hope to findout the method of teaching-learning to mathematical knowledge from the point of view that mathematical knowledge is objective; I look into how analysis into units, as the analytical method of Vygotsky, has been developed from the side of mathematical teaching-learning; I discuss the significance of mediational means to play a key role in attaining the internalization in connection with ZPD and re-illuminate imitation. Based on them, I propose how the role of mathematics teachers, and the principle of organization to mathematics textbook should be.

The acute respiratory infection known as a coronavirus (COVID-19) may present with a wide range of clinical manifestations, ranging from no symptoms at all to severe pneumonia and even death. Expert medical systems, particularly those used in the diagnostic and monitoring phases of treatment, have the potential to provide beneficial results in the fight against COVID-19. The significance of healthcare mobile technologies, as well as the advantages they provide, are quickly growing, particularly when such applications are linked to the internet of things. This research work presents a knowledge-based smart system for the primary diagnosis of COVID-19. The system uses symptoms that manifest in the patient to make an educated guess about the severity of the COVID-19 infection. The proposed inference system can assist individuals in self-diagnosing their conditions and can also assist medical professionals in identifying the ailment. The system is designed to be user-friendly and easy to use, with the goal of increasing the speed and accuracy of COVID-19 diagnosis. With the current global pandemic, early identification of COVID-19 is essential to regulate and break the cycle of transmission of the disease. The results of this research demonstrate the feasibility and effectiveness of using a knowledge-based smart system for COVID-19 diagnosis, and the system has the potential to improve the overall response to the COVID-19 pandemic. In conclusion, these sorts of knowledge-based smart technologies have the potential to be useful in preventing the deaths caused by the COVID-19 pandemic.

톡소카라증은 생간의 섭취 혹은 개의 분변으로 오염된 토양으로부터 인간에게 감염되어 호산구 증가증을 일으키는 기생충 질환으로 뇌, 눈, 폐, 간 등 다양한 장기에 증상을 일으킬 수 있다. 호산구 침윤이 일어난 장기에 따라 간 병변을 유발하거나 장벽 비후 및 복수의 증가로 나타나는 경우가 보고된 바 있으나 전신 림프절의 증대로 나타나는 것은 극히 드물다. 전신 림프절 증대로 나타난 톡소카라증은 현재까지 약 두 개의 증례 보고가 흉부와 경부, 서혜부에서 보고된 바 있다. 하지만 전신 림프절 증대로 인해 림프종으로 오인되었던 톡소카라증은 보고된 바 없어 이러한 드문 형태로 발현된 톡소카라증에 대해 증례 보고를 하고자 한다.

This paper presents methodology which enables the derivation of goal ordering rules from the analysis of problem failures. We examine all the possible ways of taking actions that lead to failures. If there are restrictions imposed by a problem state on possible actions to be taken, the restrictions manifest themselves in the form of a restricted set of possible operator bindings. Our method makes use of this observation to derive general control rules which are guaranteed to be correct. The overhead involved in learning is very low because this methodology needs only small amount of data to learn from namely, the goal stacks from the leaf nodes of a failure search tree. Empirical tests show that the rules derived by our system PAL couperform those derived by other systems such as PRODIGY and STATIC.

On 9 March 2017, a Tribunal constituted under the ICSID Convention issued its ruling in the case of Ansung Housing v. People's Republic of China, dismissing with prejudice all claims made by the Claimant, Ansung Housing Co., Ltd., in its Request for Arbitration, pursuant to ICSID Arbitration Rule 41(5). Ansung Housing v. PRC has drawn attention since it is the first case where an investor with Korean nationality initiated an ICSID arbitration on the basis of the Korea-China Bilateral Investment Treaty (BIT) as amended in 2007 between the Republic of Korea and the People's Republic of China. The Tribunal finds that its ruling is about a lack of jurisdiction of the ICSID and of its own competence as well as regarding manifest lack of legal merit due to a lack of temporal jurisdiction, since a Respondent's Rule 41(5) objection is concerned with the three-year limitation period in Article 9(7) of the Korea-China BIT. The Tribunal held that, under Article 9(7) of the Korea-China BIT, the limitation period begins with an investor's first knowledge of the fact that it has incurred loss or damage, not with the date on which it gains knowledge of the quantum of that loss or damage. Finally, the Tribunal held that Ansung submitted its dispute to ICSID and made its claim for purposes of Article 9(3) and (7) of the BIT after more than three years had elapsed from the date on which Ansung first acquired knowledge of loss or damage and that the claim is time-barred and, as such, is manifestly without legal merit. It remains to be seen whether the aggrieved Claimant initiates annulment proceedings before an ad hoc committee under the ICSID Convention. It is quite interesting to see whether the decisions by the Tribunal should be reversed on the basis of the Claimant's arguments as to the start date as well as the end date of the limitation period under the Korea-China BIT.

Inherited metabolic disorders are individually rare but as a whole, they are nor rare. Since Archibald Garrod introduced a concept of "inborn error of metabolism" or "chemical individuality", more than 500 diseases are currently known, affecting approximately one in 500 newborns cumulatively. They frequently manifest with acute, life-threatening crisis that require immediate specific intervention or they present with insidious diverse symptoms and signs involving multiple visceral organs or tissues as well as central nervous system, hampering a correct diagnosis. In addition, many pediatricians are not familiar with all diagnostic and therapeutic strategies for diverse inherited metabolic disorders. However, the prognosis of affected children are heavily dependent on rapid and effective treatment. In this lecture, practical guidelines for the specific diagnosis based on diverse clinical features of inherited metabolic disorders will be described. Many sophisticated laboratory tests are available for confirmatory diagnosis of each disease, which challenge to general pediatricians with respect to knowledge about biochemical metabolite assay test, enzymatic test and DNA diagnostic tests. Sample collections, indications, methods and interpretation of results in varying laboratory tests will be listed as well.

Colorectal cancer is one of the most severe subtypes of cancer, and has the highest propensity to manifest as metastatic disease. Because of the lack of knowledge of events that correlate with tumor cell migration and invasion, few therapeutic options are available. The current study aimed to explore the mechanism of colorectal cancer in hope of identifying the ideal target for future treatment. We first discovered the pro-tumor effect of a controversial cell cycle regulator, cylin-dependent kinase inhibitor 3 (CDKN3), which is highly expressed in colorectal cancer, and the possible related signaling pathways, by bioinformatics tools. We found that CDKN3 had remarkable effects in suppressing colorectal cancer cell proliferation and migration, inducing cell cycle arrest and apoptosis in a colorectal cancer cell line, SW480 cells. Our study, for the first time, provided consistent evidence showing overexpression of cell cycle regulator CDKN3, in colorectal cancer. The in vitro studies in SW480 cells revealed a unique role of CDKN3 in regulating cellular behavior of colorectal cancer cells, and implied the possibility of targeting CDKN3 as a novel treatment for colorectal cancer.
