This essay is dealing with Yang-Ming Studies' fundamental ideas, which are the goal of learning, the cultivation theory, and the ultimate goal in Yang-Ming-Xin-Xue. The first, what is the goal of learning in Yang-Ming-Xin-Xue: It is generally accepted idea that the goal of learning in Yang-Ming-Xin-Xue is to be a sage. But there are different suggestions about the ideas above. The reason is like this: Zhu-Zi-Studies was eager to be a sage through its cultivation theory. Yang-Ming-Xin-Xue criticized the cultivation theory in Zhu-Zi-Studies. Therefore, some people don't agree with the idea that the goal of learning in Yang-Ming-Xin-Xue is to be a sage. In this essay, I try to demonstrate that the goal of learning in Yang-Ming-Xin-Xue is to be a sage. The second, What is the major cultivation theory in Yang-Ming-Xin-Xue: The core cultivation theory is the Zhi-Ling-Zhi(Fulfillment Innate Knowledge of Goodness). For this, there is no question, but it is difficult how to learn and practice Zhi-Ling-Zhi in the daily life. I try to explain the right meaning and practice over Zhi-Ling-Zhi. The third, what is the ultimate goal in Yang-Ming-Xin-Xue: It is general method in examine Yang-Ming-Xin-Xue that is comparing with Zhu-Zi-Studies. So there is a natural tendency focusing on the differences and similarity between Yang-Ming-Xin-Xue and Zhu-Zi-Studies. But If I say, what is the ultimate goal in Yang-Ming-Xin-Xue? That is the realization of Ren, Which is the harmony with all things in heaven and earth.

The present study examined the epidermal changes of adhesive disks which occur during attachment in Parthenocissus tricuspidata using scanning and transmission electron microscopy. Several adhesive disks, each covered with a bract, develop from the shoot apical meristem during early development. In the initial stage, the adhesive disks are club-shaped and their upper and lower epidermis are indistinguishable. However, in the actively growing stage, they become spherical and both epidermis are clearly differentiated into the adventitious roots. Prior to wall attachment, the adhesive disks exhibit adaxial convex and abaxial concave shapes, and electron-dense substances are abundant in the vacuoles of epidermal cells. The peripheral area of the adhesive disk is adhered first to the wall surface, while the central area is drawn inward in a vacuum-like state during attachment. As the attachment progresses and the electron-dense substances continue to discharge, the upper and lower epidermis rapidly undergo deterioration and the disks shrink considerably. At this stage, structural changes of the lower epidermis occur much faster than in the upper one. The discharged substance is accumulated on the wall surface, and this aids the attachment of adhesive disks on the wall for long periods. In this manner, the shape and structure of the adhesive disk epidermis change drastically from initial growth to the mature stage. Further, the role of electron-dense substance and shrinkage of the disk during attachment has been discussed in Parthenocissus tricuspidata.

This study analyzes the epistemic considerations and the argumentation level revealed in the discourse of the key concept of natural selection for science-gifted elementary students. The paper analyzes and discusses the results of a three-student focus group, drawn from a cohort of twenty gifted sixth-grade elementary students. Nature, generality, justification, and audience were used to analyze epistemic consideration. Learning progression in scientific argumentation including argument construction and critique was used to analyze students' scientific argumentation level. The findings are as follows: First, Epistemic considerations in discourse varied between key concepts of natural selection discussed. The nature aspect of epistemic considerations is highly expressed in the discourse for all natural selection key concepts. But the level of generality, justification and audience was high or low, and the level was not revealed in the discourse. In the heredity of variation, which is highly expressed in terms of generality of knowledge, the linkage with various phenomena against the acquired character generated a variety of ideas. These ideas were used to facilitate engagement in argumentation, so that all three students showed the level of argumentation of suggestions of counter-critique. Second, students tried to explain the process of speciation by using concepts that were high in practical epistemic considerations level when explaining the concept of speciation, which is the final natural selection key concept. Conversely, the concept of low level of epistemic considerations was not included as an explanation factor. The results of this study suggest that students need to analyze specific factors to understand why epistemological decisions are made by students and how epistemological resources are used according to context through various epistemological resources. Analysis of various factors influencing epistemological decisions can be a mediator of the instructor who can improve the quality and level of the argumentation.

Huang Gan(1152 - 1220, pen-name Mian-zhai) was a famous scholar of Zhu-zi xue in the Southern Song period. Zhu-zi xue was also called Daoxue(道學), because it was based on the Cheng-Zhu xue(程朱學) and had very severe idea of Daotong(道統). Therefore, Zhu-zi xue emphasized practical movements of spreading Confucianism. The view of the Daotong(道統) developed in two aspects: protection of Confucianism and exclusion of Daoism Buddhism. Zhu Xi completed the idea of Daotong(道統), and his disciples, especially Huang Gan, continued his efforts. Zhu Xi's disciples searched the ultimate teaching of Confucianism through studying Four-books(四書). In due of their effort, Zhu-zi xue played a reading role in those academic fields. Huang Gan look upon himself as the successor to Zhu-zi xue. He expounded and missionized Zhu Xi's philosophical thought. In his later years, he accepted many students and passed the Zhu Xi's thought on to his students. He fostered "Jin-hua school(金華學派)"-He Ji(何基), the representative of this school. There is the relation of thought on the theory of knowledge and learning centering around Daotong between Huang Gan and Jin-hua school(金華學派). Especially, the most schools leading the academic society of Yuan period founded their thought on Huang Gan's. And it explained Huang Gan's historical influence and contributions to the Zhu-zi xue in the Yuan period.

스발바드 서측에 위치하는 스피츠버겐 하부의 암석권맨틀의 분화시기를 규명하기 위하여, 두 개의 독립적인 방사성동위원소 시스템인 Lu-Hf과 Re-Os 시스템을 스피넬 페리도타이트(spinel peridotite)에 활용하였다. 전암에 대한 Re-Os 계통(Re-Os 에러크론, 알루미노크론, Re-결핍연대 등)은 연구지역의 페리도타이트가 대류하는 맨틀로부터 고기원생대/후기시생대에 분리되었음을 지시한다. 흥미롭게도 이런 연대는 페리도타이트내 단사휘석 결정들에 대하여 얻어진 Lu-Hf 에러크론 연대와 일치한다. 또한 시료 내에 지구화학적으로 기록된 현무암질 액의 결핍정도 역시 계통적으로 위의 연대를 지지한다. 위 연대는 스피츠버겐 서측부에 보고된 가장 오래된 지각의 연대와 일치한다. 따라서 연구지역의 암석권맨틀이 연약권으로부터 분리된 것은 접촉하고 있는 지각과 동시기적으로 이루어진 사건임을 알 수 있다. 연구지역은 팔레오세 이래로 복잡한 지구조적 응력장 변화(압축에서 신장환경으로의 변화)를 겪었다. 그럼에도 불구하고 지각과 커플링된 암석권맨틀이 현존한다는 것은 연구지역내 응력장변화가 대규모의 암석권 디라미네이션(delamination)을 유발하지는 않았다는 것을 의미한다. 그러므로 북극권의 화산활동을 설명하기 위하여 북극권 상부맨틀에 존재한다고 알려진 듀팔(DUPAL) 같은 부화된 물질의 성인으로 일부의 연구자들이 주장하여 온 디라미네이션된 암석권맨틀의 존재는 설득력이 없다고 판단된다.

Objectives: In this study, we examine whether Sasang constitutions include all 8 attitude-function types, forming a complete paradigm from the perspective of Jungian psychological type theory. Methods: Analysis of the meanings of psychological attitudes and function of each Sasang constitution was performed, comparing them with the typological theories of C.G.Jung and John Beebe, both of whom are eminent minds in Jungian typology. Results and Conclusions: (1) Each Sasang constitution had all 8 psychological attitude-function combinations, which are diversely differentiated by type within their conscious and unconscious psyches. This is likely because attitudes and functions that develop in the conscious mind build up compensating attitudes and functions in the unconscious. (2) It seems that extroversion and introversion coexist within every Sasang constitution as psychological descriptions reported by Lee, Je ma state. The superior and inferior functions are disposed in the order of organ size in Sasang constitutions, but dominance of extroversion or introversion as defined by Jung's concepts of attitude does not seem to be determined by constitution.

The recent crises of Marxism do not mean Marx’s crisis. Marx said that he was not a Marxist. The purposes of this essay explore (1) the modern identity of the political economy; (2) the possibilities of mutual understanding between neoclassical economics and Marxist economics; (3) problems of the political economy in media and communication industry. I have begged for analytical Marxists, because of their good fruits. They accepted the methods of modern social science and they constituted a tremendous advance in the application of the scientific methods to the study of society. In insisting on micro-foundations(methodological individualism), analytical Marxism distinguished itself from structuralism and functionalism. I appreciate that analytical Marxism has reduced a theory to practice. But the works didn’t listen to everyone(from Marxists to un-Marxists), and explain everything. Making theory with production/consumption, macro/micro, and structure/behavior is a road to the political economy in the long run. It also applies to media and communication industry. The realm of media/communication is broad, which in philosophy, humanities, politics, economics, sociology, and engineering. And media policy is more complicated by politicians who look at the same situation from different angles. By the aid of interdisciplinary research, the political economy of media/communication shall explain at full length.

Recently, the number of social media users has increased rapidly because of the prevalence of smart devices. As a result, the amount of real-time data has been increasing exponentially, which, in turn, is generating more interest in using such data to create added value. For instance, several attempts are being made to analyze the relevant search keywords that are frequently used on new portal sites and the words that are regularly mentioned on various social media in order to identify social issues. The technique of "topic analysis" is employed in order to identify topics and themes from a large amount of text documents. As one of the most prevalent applications of topic analysis, the technique of issue tracking investigates changes in the social issues that are identified through topic analysis. Currently, traditional issue tracking is conducted by identifying the main topics of documents that cover an entire period at the same time and analyzing the occurrence of each topic by the period of occurrence. However, this traditional issue tracking approach has two limitations. First, when a new period is included, topic analysis must be repeated for all the documents of the entire period, rather than being conducted only on the new documents of the added period. This creates practical limitations in the form of significant time and cost burdens. Therefore, this traditional approach is difficult to apply in most applications that need to perform an analysis on the additional period. Second, the issue is not only generated and terminated constantly, but also one issue can sometimes be distributed into several issues or multiple issues can be integrated into one single issue. In other words, each issue is characterized by a life cycle that consists of the stages of creation, transition (merging and segmentation), and termination. The existing issue tracking methods do not address the connection and effect relationship between these issues. The purpose of this study is to overcome the two limitations of the existing issue tracking method, one being the limitation regarding the analysis method and the other being the limitation involving the lack of consideration of the changeability of the issues. Let us assume that we perform multiple topic analysis for each multiple period. Then it is essential to map issues of different periods in order to trace trend of issues. However, it is not easy to discover connection between issues of different periods because the issues derived for each period mutually contain heterogeneity. In this study, to overcome these limitations without having to analyze the entire period's documents simultaneously, the analysis can be performed independently for each period. In addition, we performed issue mapping to link the identified issues of each period. An integrated approach on each details period was presented, and the issue flow of the entire integrated period was depicted in this study. Thus, as the entire process of the issue life cycle, including the stages of creation, transition (merging and segmentation), and extinction, is identified and examined systematically, the changeability of the issues was analyzed in this study. The proposed methodology is highly efficient in terms of time and cost, as it sufficiently considered the changeability of the issues. Further, the results of this study can be used to adapt the methodology to a practical situation. By applying the proposed methodology to actual Internet news, the potential practical applications of the proposed methodology are analyzed. Consequently, the proposed methodology was able to extend the period of the analysis and it could follow the course of progress of each issue's life cycle. Further, this methodology can facilitate a clearer understanding of complex social phenomena using topic analysis.

Objective: Human embryonic stem cells (hESCs) can proliferate indefinitely and differentiate into all kinds of cell types in vitro. Therefore, hESCs can be used as a cell source for cell-based therapy. Transduction of foreign genes to hESCs could be useful for tracing differentiation processes of hESCs and elucidation of gene function. Thus, we tried to introduce enhanced green fluorescent protein (eGFP) gene to hESCs, XX and XY cell lines in this study. Methods: Lentivirus containing eGFP was packaged in 293T cells and applied to hESCs to transduce eGFP. Expression of transduced eGFP was evaluated under the fluorescence microscope and eGFP positive population was analyzed by FACS. Expression of undifferentiation state markers such as Oct4, Nanog, SSEA4 and Tra-1-81 was examined by RT-PCR and/or immunofluorescence in eGFP-hESCs after transduction. In addition, the ability of eGFP-hESCs to form embryoid bodies (EBs) was tested. Results: eGFP was successfully transduced to hESCs by lentivirus. eGFP expression was stably maintained up to more than 40 passages. eGFP-hESCs retained expression patterns of undifferentiation state markers after transduction. Interestingly, disappearance of transduced eGFP was notably observed during spontaneous differentiation of eGFP-hESCs. Conclusion: We established eGFP expressing hESC lines using lentivirus and showed the maintenance of undifferentiation characteristics of these eGFP-hESCs. This reporter-containing hESCs could be useful for tracing the processes of differentiation of hESCs and other studies.

Background : Transcriptional factors of the CREB(cAMP Response Element Binding Protein) are involved in the regulation of gene expression in response to a variety of signaling pathways. Proteins produced by the CREB genes play key roles in many physiological processes, including memory and long-term potentiation. The retinoic acid receptor (RAR) axis mediates epithelial cell differentiation and proliferation in many tissues including the lung. Material and method : The RAR and CREB expression levels were examined in 60 adenocarcinomas and 60 squamous cell carcinomas of the lung using immunohistochemical staining. Results : 1) RAR protein expression was found in 58.3%(35/60) of adenocarcinomas and 36.7%(22/60) of squamous cell carcinomas(P<0.05). 2) RAR protein expression was found in 80%(16/20) of well differentiated adenocarcinomas, 60%(12/20) of moderately differentiated adenocarcinomas, and 35%(7/20) of poorly differentiated adenocarcinomas (P<0.01). 3) RAR protein expression was found in 45%(9/20) of well differentiated squamous cell carcinomas, 35%(7/20) of moderately differentiated squamous cell carcinomas, and 30%(6/20) of poorly differentiated squamous cell carcinomas (P>0.05). 4) CREB expression was found in 61.7%(37/60) of adenocarcinomas and 40%(24/60) of squamous cell carcinomas( P<0.05). 5) CREB expression was found in 85%(17/20) of well differentiated adenocarcinomas, 60%(12/20) of moderately differentiated adenocarcinomas, and 40%(8/20) of poorly differentiated adenocarcinomas (P<0.01). 6) CREB expression was found in 45%(9/20) of well differentiated squamous cell carcinomas, 35%(7/20) of moderately differentiated squamous cell carcinomas, and 35%(8/20) of poorly differentiated squamous cell carcinomas(P>0.05). 7) RAR and CREB expression was found in 68.5% of lung cancers, and there was a significant correlation between them(P<0.05). Conclusion : RAR and CREB expression can be used to indirectly determine the malignant potentiality of a cell.
