In Nai-Gyung(內經), it is said that In-Yeong(人迎) means In- Yeong Maek(人迎脈), Gi-Gu m- eans Tson-Gu(寸口) or Maek- Gu(脈口), In-yeong, artery in the side of neck, is located before Yeong-Geun(瓔筋), called as Jok-Yang-Myung-Maek(足陽明脈),so the part of In-Yeong-Maek means In-Yeong-Hyul(人迎穴) of Jok-Yang-Myung- Wi-Gyung(足陽明胃經) showing the artery in the side of neck. The part of Tson-Gu-Maek is that of artery in Yo-Gol(橈骨), beating source of Soo-Tae-Eum-Maek (手太陰脈) Of In-Yeong-Gi-Gu-Maek, In-Yeong-Maek mainly consists of Yang(陽), Gi-Gu-Maek of Eum(陰), so In-Yeung means physical disease, short of extra Eum component. They said that if In-Yeong-Maek was more than Gi-Gu-Maek, it meant physical injury, while Gi-Gu-Maek was more than In- Yeo-ng-Maek, it meant internal injury. In-Yeong-Gi-Gu-Maek is the one to distinguish the external and internal, the inside and outside, Eum and Yang, but there is no definite classification method to distinguish it, also it is difficult to grasp the comparison of 1sung(1盛), 2sung(2盛), 3sung(3盛), interrelation with 12-Gyung-Rak(l2經絡), change of maek phases, so necessary to set up the clear definition for In-Yeong-Gi-Gu-Maek. For the two theories as to In-Yeong-Gi-Gu-Maek according to Nai-Gyung, the one is to diagnose the maek by comparing the In-Yeong-Hyul with Tson-Gu of Soo-Tae-Eum-Maek as Gi-Gu in the both sides of neck part, he other is to divide the left and right of Gi-Gu-Maek in to In-Yeong and Gi-Gu afterwards, but today it is difficult to compare and explain the medical theory afterwards owing to insufficient consideration of In-Yeong-Gi-Gu-Maek at Nai-Gyung. The diagnosis of In-Yeong-Gi-Gu-Maek at Nai-Gyung to distinguish the surplus and shortage of Eum and Yang up to now since Nai-Gyung has so important and diagnostic value as to grasp the exact meaning. Herewith, this researcher com-pared Nai-Gyung and medical theory afterwards, reported it to consider the fixed position and changing process of viscera and entrails arrangement of literatures introducing In-Yeong-Gi-Gu-Maek, examining the change of maek phases for normal maek and a-bnormal maek of In-Yeong-Gi-Gu-Maek, considering the 1 sung, 2 sung, 3 sung maek phases in In-Yeong-Gi- Gu-Maek. According to the above results, the conclusion was reached as follows. 1. In-Yeong as the outside indicates external disease(外感), showing the surplus and shortage of Yang symptom by having Boo-Maek(浮脈) as Py-ung-Maek(平脈), Gi-Gu as the inside indicates internal disease(內傷), showing the surplus and shortage of Eum symptom by having Chim-Maek(沈脈) as P-yung-Maek(平脈). 2. In Pyung-Maek of In- Yeong-Maek as Boo-Maek, g-radual sinking of more floated changing maek because of disease means the improvement of di-sease, in Pyung-Maek of Gi- Gu-Maek as Chim- Maek, gradual floating of more sunken changing maek because of disease means the improvement of disease. 3. They said that disease of Jok-Gyung-Rak(足經絡) is cha-nged to that of Soo-Kyung-Rak(手經絡) when Jo-Maek(躁脈) appears whether In-Yeong-Maek or Gi-Gu-Maek 4. With the exemples of 1 sung 2 sung 3 sung it was porned with the relation of Pyo-Ri-Soo-Jok(表裏手足). Therfore I can guess that this fact is a moment explained the Bu-You-Sa-Kyung(部有四經) mentioned in Nan-Gyung-18-Nan(難經 第18難). 5. I think that In-Yeong and Gi-Gu, as a diagnosis method which distinguish between the inside indicates internal disease and the outside indicates external disease, is required to study further researches.

Chemical and microbial characteristics of bacterial populations were investigated in a quercus and pine humus forest soil. Soil pH was $5.3\pm0.4$ and $4.1\pm0.9$ from each sample of a quercus and pine humus forest soil; C/N ratio of humus forest soil was $17.84\pm4.6%$ and $21.76\pm8%$, respectively. Total organic acid was investigated as 69.57 mM/g dry soil and 53.72 mM/g dry soil in each humus forest soil. Glutamine, pyruvate, succinate, lactic acid and acetic acid of pine humus forest soil were $1.5\sim4.5$ times higher than those of quercus humus forest soil. As we evaluated phylogenetic characteristics of bacterial populations by 16S rRNA-ARDRA analysis with DNA extracted from each humus forest soil. Based on the 16S rRNA sequences, 44 clone from ARDRA groups of quercus humus forest soil were classified into 7 phyla: ${\alpha},{\beta},{\gamma},{\delta}$-Proteobacteria, Acidobacteria, Actinobacteria, and Firmicutes. Thirty-two clone from ARDRA groups of pine humus forest soil were classified into 8 phyla: ${\alpha},{\beta},{\gamma}$-Proteobacteria, Acidobacteria, Bacteroides, Verrucomicrobia, Planctomycetes, and Gemmatomonadetes. According to PCA (Principal Component Analysis) based on 16S rRNA base sequence, there were three main groups of bacteria. All clone of Cluster I were originated from quercus humus forest soil, while 67% clone of Cluster II and 63% clone of Clusters III were separated from pine humus forest soil.

This study is to investigate the amount of biased estimates for heritability and genetic correlation according to data structure on marbling scores in Korean cattle. Breeding population with 5 generations were simulated by way of selection for carcass weight, Longissimus muscle area and latent values of marbling scores and random mating. Latent variables of marbling scores were categorized into five by the thresholds of 0, I, 2, and 3 SD(DSI) or seven by the thresholds of -2, -1, 0,1I, 2, and 3 SD(DS2). Variance components and genetic pararneters(Heritabilities and Genetic correlations) were estimated by restricted maximum likelihood on multivariate linear mixed animal models and by Gibbs sampling algorithms on multivariate threshold mixed animal models in DS1 and DS2. Simulation was performed for 10 replicates and averages and empirical standard deviation were calculated. Using REML, heritabilitis of marbling score were under-estimated as 0.315 and 0.462 on DS1 and DS2, respectively, with comparison of the pararneter(0.500). Otherwise, using Gibbs sampling in the multivariate threshold animal models, these estimates did not significantly differ to the parameter. Residual correlations of marbling score to other traits were reduced with comparing the parameters when using REML algorithm with assuming linear and normal distribution. This would be due to loss of information and therefore, reduced variation on marbling score. As concluding, genetic variation of marbling would be well defined if liability concepts were adopted on marbling score and implemented threshold mixed model on genetic parameter estimation in Korean cattle.

An experimental Chung-Kook-Jang was prepared using the strain Bacillus subtilis sp. isolated by the author Samples were taken in 12 hrs interval during the fermentation and the oligopeptides were separated by the method of molecular sieving using the ion exchange resin column of Dowex-50. Only the X-16 fraction of oligopeptides was taken and the components of oligopeptides were developed in two dimensional thin layer chromatograms. The each peptide spot was eluted and each peptide was isolated. The pattern and kinds of amino acids, and N and C-terminal amino acids were studied. Fourteen different oligopeptides could be detected by the two dimensional thin layer chromatography, all of which were consisted of $4{\sim}9$ kinds of amino acids. No dipeptides and no tripeptides could be found. The N and C-terminal amino acids and the residual component amino acids of all these 14 peptides could be summarized as the follows. [P]-I. Pro (Cys Ala Asp Trp Ile Val) Glu [P]-II. Val (His Arg Glu Thr Ala Met) Asp [P]-III. Glu (Cys Lys Asp Thr Met) Ala [P]-IV. Glu(His Ser Ala) Met) [P]-V. Ile (Cys Asp Arg Gly Pro T.p Phe) His [P]-VI.

Today, many firms face the environment of high uncertainty and severe competition due to the rapid technology development and the diverse needs of customers. In the business environment, one of the most important ways to gain sustainable competitive advantage and future growth engine is related to NPD (New Product Development), which is a very important issue for practice and academia. Thus, this study intends to provide new values to practitioners and researchers related to NPD by analyzing current research trends and future trends in NPD field. For this, we bibliometrically analyzed keyword networks which consist of keywords that were already published in the eminent journals from Scopus database to generate insights that have not been captured in the previous reviews on the topic. As a result, we could understand the extant research streams in NPD field, and suggest the changes of specific research topics based on the connected relationships among keywords over the time. In addition, we also foresaw the general future research trends in NPD field based on the keywords according to preferential attachment processes. Through this study, it was confirmed that NPD keyword network is a small world network that follows the distribution of power law and the growth of network is formed by link formation by keyword preferential attachment. In addition, through component analysis and centrality analysis, keywords such as Innovation, New product innovation, Risk management, Concurrent engineering, Research and development, and Product life cycle management are highly centralized in NPD keyword network. On the other hand, as a result of examining the change of preferential attachment of keywords over the time, we suggested the required new research direction including i) NPD collaboration with suppliers, ii) NPD considering market uncertainty, iii) NPD considering convergence with the other academic areas like technology management and knowledge management, iv) NPD from SME(Small and medium enterprises) perspective. The results of this study can be used to determine the research trends of NPD and the new research themes for interdisciplinary studies with other disciplines.

It is now well established that the rodenticide Vacor (N-3-pyridyl-mehtyl-N'-p-nitropheny-lurea) causes a hyperglycemia in human and rats. It is also reported that there are some components (DPG-3) in ginseng radix which cause hypoglycemic effect on alloxan diabetic mice. In the present study, attempts were made to demonstrate in Vacor-poisoned rats the hypo-glycemic activity of red ginseng component(RGC), which was extracted by Kimura's DPG-3 extraction procedure and found to be effective for lowering a hyperglycemia in alloxan-diabetic rats. Vacor in a dose of $LD_{50}$ (10mg/kg) produced a glucose intolerance with a paradoxical moderate increase in blood immunoreactive insulin and derangement in glucose metabolism of epididymal adipocytes in rats. Although RGC (20mg/kg, i.p.) did not exert any significant influence on a hyperglycemia induced by large lethal doses (25mg/kg) of Vacor ingestion, it improved the LDso Vacor-induced glucose intolerance and caused a further increase in blood insulin levels in Vacor-poisoned rats. The administration of RGC (20mg/kg, i.p.) normalized Vacor-induced depression of glucose metabolism and lipogenesis in the epididymal adipocytes with an improvement of reduced responses to insulin of adipocytes from Vacor-poisoned rats. These results suggest that some red ginsneng components contained in RGC fraction normalize the depressed peripheral glucose unitlization and insulin response and eventually lead to an improvement of abnormal glucose tolerance developed in rats poisoned with small doses of Vacor.

Syenite is not a common rock, unlike granitic rocks formed the major component of the continental crust. The aim of this study is to decipher the occurrences and detailed descriptive characteristics of the syenite distributed in Sancheong area, and to investigate the petrogenesis of the syenitic magma based on geochemical study. The dominant minerals in syenite are alkali feldspar (usually orthoclase and rarely microcline), plagioclase, amphibole, biotite, and quartz. Syenites are found in a wide variety of colors. The anhedral hornblende and biotite filling the boundary of feldspar and quartz indicate that the hydrous minerals were crystallized lately, and that water was insufficient at the beginning of crystallization in magma. According to the analysis of mineral composition, amphibole in syenite is mostly ferro-edenite, and the pressure is calculated as 3.3~4.9 kb with 11.9~17.3 km of emplacement depth. Biotite and pyroxene are plotted in the region of annite and hedenbergite, respectively. Based on petrochemical studies of major elements, syenite belongs to alkaline series, metaluminous, and I-type. On the other hand, the variation patterns of trace and rare earth elements of syenite differ from the patterns of diorite and granite. In the geochemical characteristics, syenite is different from gabbro-diorite spatially adjacent to syenite, as well as granite. These results suggest that each rock has been generated from the different sources of magma. Additionally, based on the experimental data, the syenitic magma can be formed (1) by the partial melting at a high pressure and dry system, (2) when the initial crystallization minerals to be residue with migration of the residual melts separated from the ascending cotectic magma (3) when fluorine compositions to be plentiful in the protolith and/or at depth of the magma. Based on the petrographic characteristics of the syenite, Sancheong syenitic magma may have been formed by partial melting in a dry system.

A study for the assessment of natural environmental radiation exposure at a flat and open field of about $10,000m^2$ in area in CNU Daeduk campus has been carried out by means of gamma-ray scintillation spectrometry and thermoluminescence dosimetry for one year period of time from October 1984. The detectors used were 3'${\phi}{\times}$3' NaI(T1) and two different types of LiF TLD, namely, chip sealed in plastic sheet which tightly pressed on two open holes of a metal plate and Teflon disk. Three 24-hour cycles of in-situ spectrometry, and two 3-month and one 1-month cycles of field TL dosimetry were performed. All the spectra measured were converted into exposure rate by means of G(E) opertaion, and therefrom exposure rate due to terrestrial component of environmental radiation was figured out. Exposure rate determined by the spectrometry was, on average, $(10.54{\pm}2.96){\mu}R/hr$, and the rates of $(12.0{\pm}3.4){\mu}R/hr$ and $(11.0{\pm}3.6){\mu}R/hr$ were obtained from chip and disk TLD, respectively. Fluctuations in diurnal variation of the exposure rate measured by the spectrometry were noticeable sometime even in a single cycle of 24 hours. It is concluded that appropriately combined use of TLD with iu-sitn gamma-ray spectrometry system can give more accurate and precise measure of environmental radiation exposure, and further study for more adequate and sensitive TLD for environmental dosimetry, including improvement and elevation of accuracy in data assessment through inter-laboratory or international intercomparison is necessary.

The chemical and optical absorption spectroscopic characters of pink and colorless tourmalines from San Diego mine in California, U.S.A., blue/green tourmalines from anonymous mine, Brazil, and brownis black tourmalines from Uncheon and Haksan mines in Korea have been studied using X-ray diffractometer, electron microprobe, optical absorption spectroscopy, and heat treatment. Least-squares refinements give unit cell diminsions : a = 15.96-16.01 ${\AA}$, c = 7.15-7.16 ${\AA}$ for the brownish black tourmalines, a = 15.82 - 15.87 ${\AA}$, c = 7.09 - 7.10 ${\AA}$ for pink tourmalines, and a = 15.88 - 15.94 ${\AA}$, c = 7.12 - 7.15 ${\AA}$ for blue green tourmalines. The colors of tourmalines are responsible for the transition elements. The pink color is attributed to the $Mn^{3+}$ ions, the blue-green to $Fe^{2+}$ and $Mn^{2+}$, bluish green to $Cu^{2+}$, and the brownish black to $Fe^{2+}$, $Fe^{2+}$ - $Fe^{3+}$, and $Fe^{2+}$ - $Ti^{4+}$. The $Mn^{3+}$ ions of pink color tourmalines are stabilized in the Y sites compressed along the O(1)H-O(3)H axis by Jahn-Teller distortion. Heating removes the pink or red component from tourmalines, producing the colorless stones from the pink and red ones. The bluish green samples change into the greenish blue ones and a certain yellowish green samples change into the light green ones by heat treatment. In the elbaite-schorl series, the concentration of Fe and Mn are variable depending on the color zones. The green zone is characterrized by the high content of Fe and Mn are variable depending on the color zones. The green zone is characterized by the high content of Fe, whereas the pink zone by the high content of Mn. Mn increases in deep yellow zone compared with yellow or colorless zones.

The study was performed to investigate the effect of gaseous emissions of sulfur dioxide and hydrogen fluoride on the growth of rice plants under stressed field conditions consisting of 88 industrial plants operating with 285 smoke stacks emitting pollutants. As for the relationship between yields and yield components it is believed that the panicles per hill is the single most important component affecting the rate of yield of the rice plant. Based on the standard partial regression coefficient analysis, panicles per hill has the largest contribution to yield and the average contribution of 54%. Other components such as spikelets per panicle, percent fertility and 1000 grain weight are also contributing factors to yield, although far less so. Fluorine content in the leaf appear to have more negative effect on panicles per hill, percent fertility and subsequent overall yield than does sulfur content in the leaf. It is constantly observed and interesting to note that fluorine and sulfur content in the leaf appears to have no effect on spikelets per panicle and 1000 grain weight. Reduction in yield seems to be affected mainly by panicles per hill which are, in turn, affected more by fluorine content in the leaf as demonstrated by the standard partial coefficient analysis. Regarding the prediction sum of the square of the regression equation, the lowest value was found when nine variables were used for the analysis. The variables taken into consideration were the monthly sulfur and fluorine content in the leaf as well as the monthly percent of leaf damage during the months of June, July and August. A significant correlation is found between the actual and predicted yields by the regression equations selected as a result of a prediction sum of the square analysis.
