Generally transition of Thought from Wang Yangming(王陽明) to Liu Zongzhou(劉宗周) is construed from emphasis of subjectivity to emphasis of intention(意; Yi). This Transition from emphasis of subjectivity to emphasis of intention is definitely expressed between Wang Yangming's Four-Sentence Teaching(四句敎) and Liu Zongzhou's explanation of Wang Yangming's Four-Sentence Teaching. Wang Yangming's Four-Sentence Teaching evoked much controversy among scholars of Yangming school. Consequently Four-Sentence Teaching's controversy caused Yangming school's division. Also this was a representative controversy on the transition period from The Ming Dynasty to The Ching Dynasty. Liu Zongzhou's critique and exposition of Four-Sentence Teaching was result from this controversy. The difference between Wang Yangming's Xinxue(心學) and Liu Zongzhou' Xinxue(心學) is due to different interpretation of intention. As is generally known Wang Yangming interprets intention is in heart stiring, but Liu Zongzhou interprets intention is being before heart stiring, immanence in heart. Liu Zongzhou suggests new exposition of Four-Sentence Teaching on intention being before heart stiring, immanence in heart. Liu Zongzhou's critique and exposition is not only criticizing Yangming's Four-Sentence Teaching, but also solves troubles of the times. As a result he promotes theory of Xinxue(心學) being peculiar his own.

There are a few changes about Wangshouren's main tenet during the process of giving lectures. because of the reason that Wangshouren give lectures changed to different disciples, so every student had his different opinion and comprehension do Wangshouren's learning, which is the main reason that Wangshouren's disciples had occurred a difference. In the thinking field of later-Ming, there had occurred a furious argument surrounding the problem of "the Heart is no Goodness and Badness or not", and how to cure the harm of the Xinxue also had become a key issue to the two sides of argument. The donglin school that Guxiancheng was its delegates made a contest with the Xinxue's scholars that Zhourudeng and Guanzhidao were that delegates, which evolved surrounding that issue that "the nature is Good" and "the Heart no Goodness and Badness". In these arguments, the two sides often persist on their own opinions, but hadn't a right understanding for Wangshouren's original meaning. Liujishan and Huanglizhou thought that the meaning of the words "the Heart no Goodness and Badness" was that the Heart have no the intention of Goodness and Badness, not that the Nature was no Goodness and no Badness. So that the opinion of "the Heart no Goodness and Badness" was not the main idea of Wangshouren. Wangji hadn't got the whole meaning of the Four Sentences. Liujishan and Huanglizhou wanted to make a new explaination to Wangshouren's ideas according to literatures and theory.

This study was carried out to investigate and evaluate the vegetations in the coastal dunes in the vicinity of swimming beaches on the East Sea, South Korea, and the vegetations that were investigated are as follows: Carex pumila community, Cynodon dactylon community, Zoysia macrostachya community, Rosa rugosa community, Vitex rotundifolia community and Carex kobomugi typical community. Some of these vegetations, such as Carex kobomugi, Calystegia soldanella, Ixeris repens, Elymus mollis, Lathyrus japonica, and Glehnia littoralis were found to be differential species which belongs to Caricion kobomugi of Glehnietea littoralis. It was also discovered that Vitex rotundifolia community was the most heterogeneous among vegetation communities of the coastal dunes surrounding swimming beaches, and Zoysia macrostachya community was most closely linked to the typical coastal dune vegetation community. Finally, Rosa rugosa community and Vitex rotundifolia community seemed to have formed near the hinterland of coastal dunes and swimming beaches respectively because of certain unnatural disturbances such as construction of buildings and facilities or natural disasters.

Purpose: The aim was to assess how the background site affects the Gates' glomerular filtration rate(GFR) measurement using Tc-99m-DTPA in correlation with GFR by I-125-lothalamate method. Material and methods: The study populations were 63 adults with 39 men and 24 women aged from 20 to 59 yrs (mean=37.9 yrs). The fellowing five background regions of interest were used in measurement of GFR using Gates' method: 1) lower side of each kidney(subrenal), 2) around each kidney(circumferential), 3) upper side of each kidney(suprarenal), 4) lateral side of each kidney(lateral), 5) between the two kidneys(inter-renal). We also measured GFR using I-125-iothalamate in each subject. The two studies were separated by 1 to 3 weeks. The subjects were divided into two groups by renal depth. Group 1 with renal $depth{\geq}7cm$ and group 2 with renal depth<7cm. We calculated the means and standard deviations of the GFRs measured by two studies. And we statistically analyzed the correlation and differences among GFRs by Gates' method and the GFR by iothalamate method with correlation analysis. Results: The GFRs by Gates' method using suprarenal and inter-renal background correction showed better correlation with the GFR measured by I-125-iothalamate. And GFRs measured by Gates' method showed statistically significant correlation with the GFR measured by I-125-iothalamate in the group with renal depth<7cm. But GFRs measured by Gates' method did not show statistically significant correlation with the GFR measured by I-125-iothalamate in the group with renal $depth{\geq}7cm$. Conclusion: GFRs measured with Gates' method showed higher correlation with the GFR measured by I-125-iothalamate when the regions of interest were plated over the suprarenal and inter-renal backgrounds. And GFRs measured with Gates method showed statistically significant correlation with the GFR measured by I-125-iothalamate in the group with renal depth<7cm.

A general idea and the structure of Wangshouren's philosophy is intimately associated with "Daxue". Systemicity of Wangshouren's Xinxue stand on the basis of a mind, intention, innate knowledge and things. "Daxuewen" is a series of a process of gongfu. It stand on the basis of a mind, intention, innate knowledge and things, same as Four-Sentence Teaching. Wangshouren's gongfu theory of "Daxue" changes from gewu to chengyi, from chengyi to zhizhi again. It is deepening of Wangshouren's philosophy and is the change of education. It is also that Wangshouren's gongfu theory internalize anything. He spent his younger life in pursuit of Zhuxi's gewu. Through a lecture of LongChang, Wangshouren's gongfu theory of "Daxue" changes from extroversion to introversion. According to Wangshouren' opinion, "Daxuewen" is the tenet of the XinXue, same as Four-Sentence Teaching. This papers mainly emphases two points: one, to analyze the thinking system of Wangshouren's "Daxuewen", make a comparative study of befour "Daxuewen" and after "Daxuewen". another, through this work we can understand thoroughly Wangshouren's viewpoint of "Daxue".

Purpose: To determine appropriate sampling frequency and time of multiple blood sampling dual exponential method with $^{99m}Tc$-DTPA for calculating glomerular filtration rate (GFR). Materials & Methods: Thirty four patients were included in this study. Three mCi of $^{99m}Tc$-DTPA was intravenously injected and blood sampling at 9 different times, 5ml each, were done. Using the radioactivity of serum, measured by gamma counter, the GFR was calculated using dual exponential method and corrected with the body surface area. Using spontaneously chosen 2 data points of serum radioactivity, 15 collections of 2-sample GFR were calculated. And 10 collections of 3-sample GFR and 12 collections of 4-sample GFR were also calculated. Using the 9-sample GFR as a reference value, degree of agreement was analyzed with Kendall's $\tau$ correlation coefficients, mean difference and standard deviation. Results: Although some of the 2-sample GFR showed high correlation coefficient, over or underestimation had evolved as the renal function change. The 10-120-240 min 3-sample GFR showed a high correlation coefficient (${\tau}=0.93$), minimal difference ($Mean{\pm}SD=-1.784{\pm}3.972$), and no over or underestimation as the renal function changed. The 4-sample GFR showed no better accuracy than the 3-sample GFR. Conclusions: In the wide spectrum of renal function, the 10-120-240 min 3-sample GFC could be the best choice for estimating the patients' renal function.

Purpose: To measure reliable glomerular filtration rate by using the representative values of transplanted renal depths, which are measured with ultrasonography. Materials and Methods: We included 54 patients (26 men, 28 women), with having both renal scintigraphy and ultrasonography after renal transplantation. We measured GFR with Gates' method using the renal depth measured by ultrasonography, and median and mean ones in each patient. We compared GFR derived from ultrasonography-measured renal depth with GFR derived from median and mean renal depths. The correlation coefficients were obtained among GFR derived from ultrasonography-measured renal depths, median and mean renal depths under linear regression analysis. We determined whether GFR derived from median or mean renal depth could substitute GFR derived from ultrasonography-measured renal depth with Bland-Altman method. We analyze the expected errors of the GFR using representative renal depth in terms of age, sex, weight, height, creatinine value, and body surface. Results: The transplanted renal depths range from 3.20 cm to 5.96 cm. The mean value and standard deviation of renal depths measured by ultrasonography are $4.09{\pm}0.65cm$ in men, and $4.24{\pm}0.78cm$ in women. The median value of renal depths measured by ultrasonography is 4.36 cm in men and 4.14 cm in women. The GFR derived from median renal depth is more consistent with GFR derived from ultrasonography-measured renal depth than GFR derived from mean renal depth. Differences of GFR derived from median and ultrasonography-measured renal depth are not significantly different in the groups classified with creatinine value, age, sex, height, weight and body surface. Conclusion: When median value is adapted as a representative renal depth, we could obtain reliable GFR in transplanted kidney simply.

The Taeanhaean National Park is located on the middle of the west coast of Korean peninsula. Due to the relatively high wave energy, large tidal range which is about 7m, and extremely complex coastal line, various coastal land-forms such as mud-flats, sand beaches, sand dunes, sea cliffs etc. are well distributed in this area, and thus various coastal ecosystems are well preserved. However, because of reckless sand diggings and construction of artificial structures in the coastal zone, the natural flowing and exchange of coastal deposits were disturbed and the erosion in the beach and the dune has been seriously accelerated. To understand of the causes of these problems, we tried three times periodical measuring with VRS/RTK GPS instrument at the Hakampo and Anmyeon beach. According to seasonal changes of the coast-line, beach area and cross-section of study sites, generally erosion process was dominated in the summer and deposition process was followed after summer.
