Confucianism acts as the representative of Chinese mainstream cultures. Its research on the relation between groups and individuals, and about norms of the system is not only complete but of a long history. And its abundant management thoughts are important assets for us to know traditional culture and construct the management study of local colors. Menzi and Xunzi both inherit Confucianism but evolve into two Confucian paths of different scenarios. Both of them are different despite sameness, and are the same despite differences. Both are artistic all right, but have their imitation. This article aims to use Mengzi thoughts and Xunzi thoughts as a study domain. The study includes five sections. The first section as an introduction presents problems. The second section uses extrinsic factors to research the birth ground of Menzi, Xunzi management thoughts. The third section examines its basic presumptions in terms of inner logic. The fifth section analyzes its logical structure, and in this section the previous sections are concluded, presenting the possible development and relative limitations of Mengzi, Xunzi management thoughts. It is expected that we can re-examine traditional Confucius thoughts from the angle of management, renewing Confucius thoughts constantly in different ages.

지면-대기상의 관계에서 지중온도와 토양수분의 역할이 중요함에도 불구하고 이들 변수의 다양한 시공간적 변동성, 관측자료의 한계, 관련자료 및 이해 부족 등으로 인하여 아직까지 체계적인 연구가 이루어지지 못하고 있다. Idso 등(1975)에 의해 처음 토양수분과 지중온도에 대한 연구를 시작으로 Lakshmi 등(2003)은 지중온도가 토양수분과 역의 관계를 가짐을 도출하였으며 이를 이용한 선형회귀분석을 수행하여 토양수분을 예측하였다. 기존연구를 바탕으로 본 연구에서는 설마천 타워(Flux tower)에서 기록된 지중온도와 토양수분 자료를 이용하여 사계절에 따른 상관관계를 분석하였다. 조사기간 동안 토양수분은 봄부터 가을까지의 경우 지중온도가 강한 음의 상관계수를 가지는 반면 겨울의 경우 지중온도와 강한 양의 상관계수를 가지는 것으로 판단이 되었다. 즉, 계절에 따라 지중온도와 토양수분의 관계가 차이가 있음을 알 수 있다. 또한, 본 연구에서 토양수분에 대한 지중온도의 계절별 선형적 관계를 도출하였으며 지표상의 물 에너지 순환에 대한 보다 나은 이해를 줄 것으로 사료된다.

Background : Matrix metalloproteinases(MMPs) are a large family of proteolytic enzymes, which are involved in the degradation of many different components of the extracellular matrix. There is increasing evidence indicating that individual MMPs have important roles in tumor invasion by inactivating the MMPs. In this study, the correlation between MMPs and TIMPs expression, and the clinical outcome was investigated. Materials and Methods : Immunohistochemical staining of MMP-2, 9 and TIMP-1,2 were performed on paraffin-embedded tumor sections from 74 resected primary non-small cell lung cancers. Results : In 74 patients, MMP-2, MMP-9, TIMP-1, and TIMP-2 immunoreactivity was demonstrated in 24(34%), 19(26%) and 32(43%) of the paraffin-embedded tumors, respectively. The median survival of the MMP-2 positive cases was significantly shorter than that of the negative cases(20 vs 34 months). The median survival of the TIMP-2 positive cases was also was significantly longer than that of the negative cases (34 vs 18 months). The MMP-2, and MMP-9 expression level had a positively correlation with a more advanced stage and lymph node metastasis. There was inverse correlation between TIMP-2 expression and tumor invasion. The median survival of the MMP-2 negative/TIMP-2 positive cases was higher than that of the other cases. Conclusion : These results suggest that tumor invasion and lymph node metastasis are closely related to MMP-2 and MMP-9 expression. There was an inverse correlation between TIMP-2 and MMP-9 expression, and tumor invasion.

Since the output of retina for visual stimulus is carried by neurons of very diverse functional properties, it is not adequate to use conventional single electrode for recording the retinal action potential. For this purpose, we used newly developed multichannel recording system for monitoring the simultaneous electrical activities of many neurons in a functioning piece of retina. Retinal action potentials are recorded with an extra-cellular planar array of 60 microelectrodes. In studying the collective activity of the ganglion cell population it is essential to recognize basic functional distinctions between individual neurons. Therefore, it is necessary to detect and to classify the action potential of each ganglion cell out of mixed signal. We programmed M-files with MATLAB for this sorting process. This processing is mandatory for further analysis, e.g. poststimulus time histogram (PSTH), auto-correlogram, and cross-correlogram. We established MATLAB based protocol for waveform classification and verified that this approach was effective as an initial spike sorting method.

Molecular phylogenetic studies were conducted to evaluate interspecific relationships in 40 populations of Viola including 35 Korean taxa, four Japanese populations and one outgroup using nuclear ribosomal ITS sequences. The phylogenetic analyses were conducted using parsimony and neighbor-joining methods. Subsection Trigonocarpae of section Nomimium appeared as the most basal clade within the Korean Viola. Section Dischidium and Chamaemelanium was monophyletidbootstrap 100%) and placed between subsect. Trigonocarpae and three other subsections of sect. Nomimium. Sect. Nomimium was paraphyletic. Although each subsectional grouping was in accordance with previous infrageneric classification based on morphological characters, yet discordance remained at the series level. Two evolutionary trends observed in the ITS tree were as follows. First, subsect. Trigonocarpae(x=10) was derived from the outgroup(x=6); Second, subsects. Bilobatae and Vaginatae(x=10 or 12), and subsect. Patellares(x=12) of sect. Nomimium were originated from sects. Dischidium and Chamaemelanium(x=6). Viola albida complex including three very closely related taxa was recognized as independent group within subsect. Patellares in parsimony tree. This result suggested that they should be treated as a taxa in series Pinnatae. Phylogenetic position of a putative hybrid species, Viola woosanensis was not supported with previous morphological hypothesis.

History is not only Hegel's philosophical subject, but it corresponds to his entire system of philosophy. Because his system of philosophy is a description of the self-movement of spirit and 'world history' reveals the overall movement of spirit. Hegel's 'historical and philosophical standpoint' goes through the description of his entire system, and this tendency is more and more reinforced towards the later Hegel. If it is reasonable to find the corresponding relationship between Hegel's system of philosophy and 'world history', the relationship between 'objective spirit' and 'absolute spirit' must be systematically unraveled in the horizon of world history. The world-historical perspective in 'objective spirit' has the limit to consider 'modern European nations' as a final destination. On the contrary, world history that acts as a mediator in the transition from 'objective spirit' to 'absolute spirit' makes it possible to jump in absolute horizon by recognizing limitations of nation states and avoiding specific and limited conditions dialectically. So what is revealed through the study of 'world history' in Hegel's system of philosophy is that in the view of 'absolute spirit' of art, religion, philosophy 'political state' is not the end that all mankind should aim at. Therefore, it is undesirable only to criticize Hegel's philosophy of history as 'Eurocentrism'.
