이전 연구에서는 사파이어 기판 위에 이종에피성장 방법으로 성장한 높은 인듐 조성의 극박 InGaN/GaN 다층 양자우물 구조를 이용한 근 자외선 (near-UV) 영역의 광원에 대하여 보고하였다. 본 연구에서는 HVPE (Hydride Vapor Phase Epitaxy) 법을 이용하여 성장된 free-standing GaN 기판 위에 유기금속 화학증착법 (MOCVD) 을 이용하여 GaN 동종에피박막과 높은 인듐 조성의 InGaN/GaN 다층 양자우물을 성장하였고 그 특성을 분석하였다. Free-standing GaN 기판은 표면 조도가 0.2 nm 인 평탄한 표면을 가지며 $10^7/cm^2$ 이하의 낮은 관통전위밀도를 가진다. Freestanding GaN 기판 위에 성장 온도와 V/III 비율을 조절하여 GaN 동종에피박막을 성장하였다. 또한 100 nm 두께의 동종 GaN 박막을 성장한 후에 활성층으로 이용될 높은 인듐 조성의 InGaN/GaN 다층 양자우물구조를 성장하였다. Free-standing GaN 기판 위에 성장된 GaN 동종에피박막과 다층 양자우물구조의 표면 형상은 주사 탐침 현미경 (scanning probe microscopy, SPM) 을 이용하여 관찰하였고 photoluminescence (PL) 측정과 cathodoluminescence (CL) 측정을 통하여 광학적 특성을 확인하였다. 사파이어 기판 위에 성장된 2 um 의 GaN을 이용하여 성장된 높은 인듐 조성의 InGaN/GaN 다층 양자우물의 결함밀도는 $2.5 \times 10^9/cm^2$ 이지만 동일한 다층 양자우물구조가 free-standing GaN 기판 위에 성장되었을 경우 결함 밀도는 $2.5\;{\times}\;10^8/cm^2$로 감소하였다. Free-standing GaN 기판의 관통전위 밀도가 $10^7/cm^2$ 이하로 낮기 때문에 free-standing GaN 기판에 성장된 높은 인듐 조성의 다층 양자우물구조의 결함밀도가 GaN/sapphire 에 성장된 다층 양자우물의 결함밀도 보다 감소했음을 알 수 있다. Free-standing GaN 기판에 성장된 다층 양자 우물은 성장온도에 따라 380 nm 에서 420 nm 영역의 발광을 보이며 PL 강도도 GaN/sapphire 에 성장한 다층 양자우물의 PL 강도 보다 높은 것을 확인할 수 있다. 이것은 free-standing GaN 기판에 성장된 높은 인듐 조성의 InGaN/GaN 다층 양자우물구조의 낮은 결함밀도로 인하여 활성층의 발광 효율이 개선된 것임을 보여준다.

Tongue examination is the most unique and important diagnostic method of oriental medicine. It reveals patients condition and give some information about direction of therapy and background of disease as well as produces clue of duration of disease changing that grasps it from outside. The aims of this study show that results of tongue examination is related to somewhat special pattern. we study 27 patients(age of means: 63.01 years old, male: 14, female: 13) who come to Wonkwang University Oriental-Medicine Hospital at Chonju with diabetes mellitus or diabetes mellitus complications. Tongue colors of this study result in pale-red 8 cases, pale 6 cases, red 6 cases, crimson 5 cases, blue-green-purple 2 cases and tongue fur of this study result in white-fur 16 cases, yellow-fur 7 cases, black-fur 1 case, none-fur 3 cases. And the condition of tongue fur with grimy and thin result in thin-white-fur 12 cases, white-grimy-fur 4 cases, thin-yellow-fur 5 cases, grimy-yellow-fur 2 cases, black-fur 1 case. Means level of fasting glucose during 7 days was $223.24{\pm}32.l7mg/dl$ and postprandial 2hours was $286.37{\pm}24.54mg/dl$ There were no changes in tongue body and tongue color but changes occur in tongue fur with 9cases in this period. 5 cases of patient make a difference between FBS(fasting blood glucose) and postprandial blood glucose level more than l00mg/dl (2 cases of patient with thin-white-fur gradually turned to slight-yellow-fur. There were no changes in 2 cases of patient with crimson-none-fur and pale-white-fur. 1 case of patient with slimy-yellow-fur turned to black fur.) 11 cases of patient had lesser than $10\%$ hemoglobin $A_lC$ and tongue color of these patient were pale-red 5cases, pale 2 cases, red 2 cases, crimson 2 cases. 16 cases of patient had more than $10\%$ Hemoglobin $A_1C$ and tongue color of these patients were pale-red 3 cases, pale 4 cases, red 4 cases, crimson 3 cases, blue 2 cases. This result shows that quantity of Hemoglobin $A_1C$ make a somewhat role in tongue color. The above results show that tongue color, fur color, condition and change of fur in diabetes mellitus patients is various in pale-red, pale, crimson, none-fur. So it is difficult to give an exact diagnosis on pathology of diabetes mellitus only with tongue examination because there are a little matches between blood glucose level, prevalence-period, short-term blood glucose regulation and tongue and fur colors.

A survey was conducted to investigate the chemical properties of soils such as pH, electrical conductivity, total organic matter content, soluble nitrate, available phosphate and major exchangeable canons, in plastic film houses at 513 sites. All the parameters surveyed in the plastic film house were much higher than those of open field soils. Particularly conspicuous was the accumulation of available P, exchangeable K and the occurrence of nitrate at relatively high concentration in both top soil(0-20 cm) and sub-soil(20-40 cm). In 70-80% of cases, the contents of available P and exchangeable K in top soils, were found to be higher than optimum levels. There was positive linear correlation between the content of exchangeable rations, and nitrate and EC of soils. The correlation coefficient was greater in the order of nitrate-EC > Mg-nitrate > K-nitrate > Ca-nitrate. The successive cultivation of horticultural crops in the plastic houses tended result in the accumulation of available P, exchangeable K and total organic matter in the soil.

This study was conducted to examine the effects of auricular acupressure on quality of sleep and depression. Adults who had insomnia for over 1 month were recruited. Participants were distributed randomly to the experimental group(n=22) and the control group(n=22). The experimental group received auricular acupressure on Shen men(TF2), insomnia 1(SF4), insomnia 2(SF1), and anti-depression(LO8) for 1 week. The contrast group received sleep hygiene education. The mean differences of the quality of sleep were 4.05±2.52 in the experimental group and 1.45±3.77 in the control group. Auricular acupressure significantly decreased insomnia in the experimental group compared to the control group(t=3.07, p=.004). Depression scores after acupressure were not different between the experimental group and the control group. After controlling the religion as a covariate, the mean difference of depression in the experimental group was higher than the control group(F=4.22, p=.046). In conclusion, auricular acupressure decreased insomnia and depression. Therefore, further studies on different acupressure points such as shen men, jiao gan, heart, pi zhi xia, and endocrine are recommended.

A new cold tolerant germplasm resource named glutinous rice 89-1 (Gr89-1, Oryza sativa L.) can overwinter using axillary buds, with these buds being ratooned the following year. The overwintering seedling rate (OSR) is an important factor for evaluating cold tolerance. Many quantitative trait loci (QTLs) controlling cold tolerance at different growth stages in rice have been identified, with some of these QTLs being successfully cloned. However, no QTLs conferring to the OSR trait have been located in the perennial O. sativa L. To identify QTLs associated with OSR and to evaluate cold tolerance. 286 $F_{12}$ recombinant inbred lines (RILs) derived from a cross between the cold tolerant variety Gr89-1 and cold sensitive variety Shuhui527 (SH527) were used. A total of 198 polymorphic simple sequence repeat (SSR) markers that were distributed uniformly on 12 chromosomes were used to construct the linkage map. The gene ontology (GO) annotation of the major QTL was performed through the rice genome annotation project system. Three main-effect QTLs (qOSR2, qOSR3, and qOSR8) were detected and mapped on chromosomes 2, 3, and 8, respectively. These QTLs were located in the interval of RM14208 (35,160,202 base pairs (bp))-RM208 (35,520,147 bp), RM218 (8,375,236 bp)-RM232 (9,755,778 bp), and RM5891 (24,626,930 bp)-RM23608 (25,355,519 bp), and explained 19.6%, 9.3%, and 11.8% of the phenotypic variations, respectively. The qOSR2 QTL displayed the largest effect, with a logarithm of odds score (LOD) of 5.5. A total of 47 candidate genes on the qOSR2 locus were associated with 219 GO terms. Among these candidate genes, 11 were related to cell membrane, 7 were associated with cold stress, and 3 were involved in response to stress and biotic stimulus. OsPIP1;3 was the only one candidate gene related to stress, biotic stimulus, cold stress, and encoding a cell membrane protein. After QTL mapping, a total of three main-effect QTLs-qOSR2, qOSR3, and qOSR8-were detected on chromosomes 2, 3, and 8, respectively. Among these, qOSR2 explained the highest phenotypic variance. All the QTLs elite traits come from the cold resistance parent Gr89-1. OsPIP1;3 might be a candidate gene of qOSR2.

The purpose of this paper is to explore the possibility of backwards causation. For study, this paper was divided into four views as follows: The first view was sometimes suggested by the people such as M. Dummett who distinguished observers from behaviors. According to observers' view, backwards causation is impossible, whereas behaviors' view possible. However, in a real or genuine sense, it is incorrect for us to argue for impossibility of backwards causation from the observer aspect. The second view was supported by J. H. Schmidt. He analyzed the possibility of backwards causation in terms of macro and micro level analysis about the causal events. According to micro level analysis, backwards causation is possible, but macro level analysis impossible. Usually the latter makes the former something miraculous. Under the macro level analysis, backwards causation, at first, seems to be miraculous phenomena which belongs to the micro level analysis. The third view had to do with physical equation, and the fourth view physical phenomena, respectively. John Earman argued for the backwards causation by the transformation from Lorentz­-Dirac equation to a second-order integro-differential one in the field of electrodynamic acceleration. His argument was criticized because of his misunderstanding about the relationship between two equations. On the other hand, Phil Dowe defended a version of Reichenbach's own theory about the direction of causation founded on the fork asymmetrical causal relation. However his view was different from Reichenbach's because the former defended the backwards causation model of Bell phenomena in quantum mechanics. On the contrary, Reichenbach put stressed on the priority of cause in the causal process. Subjectivism has recently been defended by H. Price, under the label of perspectivism. According to him, in a certain sense causal asymmetry is not in the world, but is rather a product of our own asymmetric perspective on the world. He also suggested causal net, the symmetry of microphysics, and so on. As mentioned above, there are many kind of suggestions of backwards causation. However none of them replaced objectively the main streams of the direction of causal process. The main stream has been usually defended by pragmatical ground. That is, effects do not precede their causes although causes cannot be without their effects.

Background: Ginsenoside compound K (CK) is a promising drug candidate for rheumatoid arthritis. This study examined the impact of polymorphisms in NR1I2, adenosine triphosphate-binding cassette (ABC) transporter genes on the pharmacokinetics of CK in healthy Chinese individuals. Methods: Forty-two targeted variants in seven genes were genotyped in 54 participants using Sequenom MassARRAY system to investigate their association with major pharmacokinetic parameters of CK and its metabolite 20(S)-protopanaxadiol (PPD). Subsequently, molecular docking was simulated using the AutoDock Vina program. Results: ABCC4 rs1751034 TT and rs1189437 TT were associated with increased exposure of CK and decreased exposure of 20(S)-PPD, whereas CFTR rs4148688 heterozygous carriers had the lowest maximum concentration ($C_{max}$) of CK. The area under the curve from zero to the time of the last quantifiable concentration ($AUC_{last}$) of CK was decreased in NR1I2 rs1464602 and rs2472682 homozygous carriers, while $C_{max}$ was significantly reduced only in rs2472682. ABCC4 rs1151471 and CFTR rs2283054 influenced the pharmacokinetics of 20(S)-PPD. In addition, several variations in ABCC2, ABCC4, CFTR, and NR1I2 had minor effects on the pharmacokinetics of CK. Quality of the best homology model of multidrug resistance protein 4 (MRP4) was assessed, and the ligand interaction plot showed the mode of interaction of CK with different MRP4 residues. Conlusion: ABCC4 rs1751034 and rs1189437 affected the pharmacokinetics of both CK and 20(S)-PPD. NR1I2 rs1464602 and rs2472682 were only associated with the pharmacokinetics of CK. Thus, these hereditary variances could partly explain the interindividual differences in the pharmacokinetics of CK.

The Ho-Rak controversy is an internal dispute in the Kiho School. Both Ho and Rak adopt the theories of Yulgok(栗谷) as their common standard of right arguments. The controversy continues almost two hundred years after the dispute between LEE Gan(李柬) and HAN Wonjin(韓元震). However, it does not develop rich theoretical resources. The fundamental issue of Ho-Rak controversy is how to define the relation of mind(心) and temper(氣質). Ho School regard temper as material of the mind, and so they insist that mind and temper are ultimately the same. But Rak School regard temper as desire of the body, and so they insist that mind and temper are the another one. The viewpoint of Rak School does not correspond to the view of the traditional Neo-confucianism. So we should understand that mind and temper are ultimately the same. However if we define that mind and temper are the same, and they act at the same time, then we can not insure the foundation of pure goodness in human mind. LEE Chulyoung(李喆榮) defines that mind and temper are ultimately the same, but they act alternately. It is the exact definition about the relation of mind and temper.

Objective: To conserve and utilize the genetic resources of a traditional Chinese indigenous pig breed, Liangshan pig, we assessed the genetic diversity, genetic structure, and genetic distance in this study. Methods: We used 50K single nucleotide polymorphism (SNP) chip for SNP detection of 139 individuals in the Liangshan Pig Conservation Farm. Results: The genetically closed conserved population consisted of five overlapping generations, and the total effective content of the population (Ne) was 15. The whole population was divided into five boar families and one non-boar family. Among them, the effective size of each generation subpopulation continuously decreased. However, the proportion of polymorphic markers (P_N) first decreased and then increased. The average genetic distance of these 139 Liangshan pigs was 0.2823±0.0259, and the average genetic distance of the 14 boars was 0.2723±0.0384. Thus, it can be deduced that the genetic distance changed from generation to generation. In the conserved population, 983 runs of homozygosity (ROH) were detected, and the majority of ROH (80%) were within 100 Mb. The inbreeding coefficient calculated based on ROH showed an average value of 0.026 for the whole population. In addition, the inbreeding coefficient of each generation subpopulation initially increased and then decreased. In the pedigree of the whole conserved population, the error rate of paternal information was more than 11.35% while the maternal information was more than 2.13%. Conclusion: This molecular study of the population genetic structure of Liangshan pig showed loss of genetic diversity during the closed cross-generation reproduction process. It is necessary to improve the mating plan or introduce new outside blood to ensure long-term preservation of Liangshan pig.
