  • Objectives : Due to the morphological similarity of in the roots of herbal medicine, the official herbal medicine is very difficult to authenticate between the original plants of Patriniae Radix and two adulterant Patrinia species. Therefore, we introduced DNA barcode analysis to establish a powerful tool for the authentication of Patriniae Radix from its adulterants. Methods : To analyze DNA barcode regions, genomic DNA was extracted from twenty-nine specimens of Patrinia scabiosaefolia, Patrinia villosa, Patrinia saniculifolia, and Patrinia rupestris, and internal transcribed spacer 2(ITS2), matK and rbcL genes were amplified. For identification of species specific sequences, a comparative analysis was performed by the ClastalW based on entire sequences of ITS2, matK and rbcL genes, respectively. Results : In comparison of three DNA barcode sequences, we identified 22, 22, and 12 species-specific nucleotides enough to distinguish each four species from ITS2, matK and rbcL gene, respectively. The sequence differences at the corresponding positions were available genetic marker nucleotides to discriminate the correct species among analyzed four species. These results indicated that comparative analysis of ITS2, matK and rbcL genes were useful genetic markers to authenticate Patriniae Radix. Conclusions : The marker nucleotides enough to distinguish P. scabiosaefolia, P. villosa, P. saniculifolia, and P. rupestris, were obtained at 22 SNP marker nucleotides from ITS2 and matK DNA barcode sequences, but they were confirmed at 12 SNP marker nucleotides from rbcL. These differences could be used to authenticate Patriniae Radix from its adulterants as well as discriminating each four species.

  • Purpose : To assess target motion during radiotherapy by quantifying daily setup errors and inter-fractional and intra-fractional movements of pancreatic fiducials. Materials and Methods : Eleven patients were treated via stereotactic body radiotherapy (SBRT) with volumetric modulated arc therapy. Bony setup errors were calculated using cone beam computed tomography (CBCT). Inter-fractional and intrafractional fiducial (seed) motion was determined via cone beam computed tomography (CBCT) projections and orthogonal fluoroscopy. Results : Using an off-line correction protocol, setup errors were 0.0 (-1.7-4.0), 0.3 (-0.5-3.0), and 0.0 (-4.1-6.6) mm for the left-right, anterior-posterior, and superior-inferior directions respectively. Random inter-fractional setup errors in the mean fiducial positions were -0.1, -1.1, and -2.3 mm respectively. Intra-fractional fiducial margins were 9.9, 7.8, and 12.5 mm, respectively. Conclusion : Online inter-fractional and intra-fractional corrections based on daily kV images and CBCT expedites SBRT of pancreatic cancer. Importantly, inter-fractional and intra-fractional motion needs to be measured regularly during treatment of pancreatic cancer to account for variations in patient respiration.

  • The purpose of this study is to evaluate the accuracy of Network-RTK(VRS) survey for applying to Ground Control Points(GCPs) survey required for mapping aerial photographs. Network-RTK has been serviced by National Geographic Information Institute since 2007. On the basis of the global coordinates system(ITRF2000), the coordinates of GCPs determined by Static GNSS survey with relative positioning techniques were regarded as accurate values. The coordinates of GCPs were also determined by Network-RTK survey using two kinds of receivers, and then they were converted into the global coordinates system(ITRF2000) by applying suitable geoid model and coordinate transformation. These coordinates of GCPs were compared with those from Static GNSS survey. The root mean squares error (RMSE) of coordinate differences between Network-RTK and Static GNSS was ${\pm}2.0cm$ in plane and ${\pm}7.0cm$ in height. Therefore, Network-RTK survey that enables single GNSS receiver to measure positions in short time is a practical alternative in positioning GCPs to either RTK survey that uses more than two sets of GNSS receivers or Static GNSS survey that requires longer observation time.

  • In July 1993 a new prescription of the EC was finished, concerning the voluntary participation of enterprises in a common auditing system. By this in the EC-member countries there must be founded centers of environmental auditing where experienced experts of environmental auditing should be accredited. These accredited experts are controllers for evaluating and certification of carried out environmental-auditings. An environmental-auditing practically represents an environmental assessment for an already existing enterprise with establishing corresponding programmes and strategies for the internal management to improve the environmental relations. Much experiences, which could be collected in the field of EIA during the last years may be transfered to this new task immediately. Only an essential difference there should not be overseen because of national legislation EIA in the defined cases must be carried out. By the EC-prescription carrying out an environmental-auditing for an enterprise is optional, it is recommended only. It was not introduced as a must. In spite of this fact because of the hard competition on the market there will be developed a pressure for the enterprises, to carry out such environmental-auditings. At present already a number of first projects in this direction can be seen, in the first line above all enterprises with the necessary economic power want to use this possibility, to gain better positions on the market. We have already gathered the first experiences in this field. We arranged corresponding contacts to several enterprises within the surroundings of Dresden. Within an opening discussion, where the project is explained and discussed with the management of the enterprise very detailed, the understanding, the readiness and the cooperation for the project are generated necessary prerequesits for the success of the whole work. By means of careful detail-work in collaboration with all departments and on all levels of the enterprise the total mass and energy-balances of the factory established and analysed. There are included also such ranges like material delivery, personal policy, public relations and sale as well as waste management. It is important that all people working in the factory have the feeling to be our partners, and not to have the impression to be checked or controled by an outside organization. This one of the most important factors of environmental auditing, in order to wake up and to develop a common interest on all sides. At the end of the environmental auditing there will be according to the prescription of the EC a catalogue of measures to do immediately, short time, mean time and long time for improvement of the environmental situation of the enterprise. All proposals are made in connection with a corresponding economic evaluation. These measures and programmes are declared as the environmental manual and are the basis for the work of the environmental management of the enterprise for the next three years. According to the EC-prescription, the enterprise with this environmental manual can get a corresponding certificate, which may be used for public relation purposes.

  • In this paper, we propose a horizontal/vertical calibration kit for calibrating a vector network analyzer(VNA) to measure the vertical connector pin. If the conventional calibration kit is used, we should change the arm for a probe or need an assistant device and it takes a long time. In addition there is a risk of precision degradation caused by the position change of the probe tip sensitive to the surroundings. We suggest a 4-port vertical calibration kit to make up for the aforementioned shortcomings. The calibration kit was manufactured for the SOLT calibration method. 'Short', 'Open', and 'Load' are available in the horizontal plane, 'Thru' is available not only in the horizontal plane on the two planes of a PCB, but in the vertical plane between the two planes according to the positions of the probes. We complemented the conventional calibration kit to make a vertical calibration kit to be used for the vertical measurement method. We compared and analysed their reflection/transfer characteristics of the SOLT calibration standards of the proposed calibration kit and conventional one, we get a ${\pm}0.1$ dB differences of transfer characteristics in the range from 300 kHz to 8.5 GHz. In order to demonstrate usefulness, and we performed a case study for horizontal and vertical cases, and compared the results of the proposed calibration kit and conventional one.

  • It has been shown that a nucleotide substitution at position 770 in Escherichia coli 16S rRNA, which is implicated in forming the evolutionary conserved B2c intersubunit bridge, has a detrimental effect on ribosome function. In order to isolate second-site revertants that complement ribosomes containing C770G, we performed a random mutagenesis of the 16S rRNA gene and selected clones that could produce more CAT protein translated by specialized ribosome. One of the clones contained two nucleotide substitutions at positions 569 and 904 (C569G and U904C) and these mutations partially complemented the loss of protein-synthesis ability caused by C770G. Further studies using the isolated revertant will provide information about which part of 16S rRNA is interacting with C770 and the consequence of the structure formed by these interactions in the process of protein synthesis.

  • The objective of this study was to investigate the correlation between cattle breeds and deposit of adipose tissues in different positions and the gene expressions of peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$), fatty acid synthase (FASN), and Acyl-CoA dehydrogenase (ACADM), which are associated with lipid metabolism and are valuable for understanding the physiology in fat depot and meat quality. Yanbian yellow cattle and Yan yellow cattle reared under the same conditions display different fat proportions in the carcass. To understand this difference, the expression of $PPAR{\gamma}$, FASN, and ACADM in different adipose tissues and longissimus dorsi muscle (LD) in these two breeds were analyzed using the Real-time quantitative polymerase chain reaction method (qRT-PCR). The result showed that $PPAR{\gamma}$ gene expression was significantly higher in adipose tissue than in LD in both breeds. $PPAR{\gamma}$ expression was also higher in abdominal fat, in perirenal fat than in the subcutaneous fat (p<0.05) in Yanbian yellow cattle, and was significantly higher in subcutaneous fat in Yan yellow cattle than that in Yanbian yellow cattle. On the other hand, FASN mRNA expression levels in subcutaneous fat and abdominal fat in Yan yellow cattle were significantly higher than that in Yanbian yellow cattle. Interestingly, ACADM gene shows greater fold changes in LD than in adipose tissues in Yan yellow cattle. Furthermore, the expressions of these three genes in lung, colon, kidney, liver and heart of Yanbian yellow cattle and Yan yellow cattle were also investigated. The results showed that the highest expression levels of $PPAR{\gamma}$ and FASN genes were detected in the lung in both breeds. The expression of ACADM gene in kidney and liver were higher than that in other organs in Yanbian yellow cattle, the comparison was not statistically significant in Yan yellow cattle.

  • Based on the community structural attributes, such as species composition, diameter and height distribution, topographic position, and species diversity in the natural deciduous forest of Mt. Gari area, this study suggested desirable species and composition ratio to achieve ecological management of forests so as to maintain forest stability and enhance economical values. The results are as follows : 1. Twenty-five tree species were growing in the study forest. Of these Quercus mongolica, Pinus densiflora, Juglans mandshurica, Quercus serrata, Cornus controversa, Acer mono, Fraxinus rhynchophylla, and Tilia mandshurica were selected for desirable species through the evaluation of dominant and dominant potential. Kalopanax pictus, considered to be highly valuable species, was also included. 2. Taking account of different species composition pattern by topographic positions, we select as desirable species of J. mandshurica, C. controversa, Q. mongolica, A. mono, T. mandshurica, and F. rhynchophylla in the valley area, Q. mongolica, Q. serrata, A. mono, T. mandshurica, F. rhynchophylla, and K. pictus in the mid-slope area, and Q. mongolica, P. densiflora, Q. serrata, and Fraxinus rhynchophylla in the ridge area. 3. Based on the estimation of species diversity index for the overstory components, the reasonable forest stability levels of the indices were estimated at 1.96, 1.68, 1.94, and 1.27 for whole forest, valley, midslope, and ridge, respectively. 4. The recommended species composition ratios in the study forest were suggested Q. mongolica to be 30%, A. mono, F. rhynchophylla, Q. serrata, and T. mandshurica to be 10%~15%, J. mandshurica, P. densiflora, and C. controversa to be 5%~10%, and K. pictus to be 5%.

  • Cancer causes many crises to cancer patients imcluding physical dysfunction and emotional changes such as anxiety, depression as well as a threat of life, fear of death. As it develops, cancer makes people feel powerlessness due to the losses of their own positions, roles and independence. Although occupying a little proportion among all types of cancer, head and neck cancer may cause a wide range of physical transformation by surgical operation, damage to active functions such as eating and speaking, provoke anxiety and depression after its operation, influencing the quality life of head and neck cancer patients. Thus nursing intervention should be developed to provide supportive nursing for head and neck cancer patients and play roles as competent supporters. This study is a nonequivalent, control group, pretest-posttest, non-synchronized quasi-experimental research design to determine, how nursing intervention has effects on anxiety, depressing of head and neck cancer and operated. They were divided into experimental and comparison groups, each consisting of 20 members. The data were collected during the period from December 1, 1999 to April 11, 2000. Tools of the study included the protocol of supportive nursing intervention which was developed by researcher with reference to a literal review and esperts' advice. The measurement tool of anxiety was consisting of totaled 20 question items which was prepared by Spielberger and translated by Kim et al., the device of depression measurement consisting of total 20 question items which was the output of Song's translation the device of depression self-evaluation from Zung. Data were analyzed using the SPSS/PC 9.0 program. The homogeneity of the subjects were tested using x2-test and t-test. 5 hypoteses were tested using t-test. The results of the study can be summarized as follows. 1.The first hypothesis that the experimental group receiving supportive nursing intervention shows a little anxiety than the control group not receiving supportive nursing intervention was supported(t=3.817, P=.000). 2.The second hypothesis that the experimental group receiving supportive nursing intervention shows a little depression than the control group not receiving supportive nursing intervention was supported(t=8.089, P=.000). Consequently, supportive nursing intervention was found an effective nursing intervention strategy to reduce anxiety and depression of head and neck cancer patients. Providing supportive nursing intervention in nursing practice can enhance the quality of life of those cancer patients.

  • This study evaluated the moral sensitivity, self-assertiveness, ethical decision-making confidence and their correlations, and the factors that influence ethical decision-making confidence among nurses working in a long-term care hospital. Overall, 149 nurses working in a long-term care hospital in G Province were evaluated. The date was collected from November 30 2019 to December 18, 2019 and analyzed using SPSS/WIN 21.0 program. The mean of moral sensitivity among nurses was 4.94, the mean of self-assertiveness was 3.17 and the mean of ethical decision-making confidence was 3.49. The self-assertiveness will, according to the general characteristics, was significantly different according to experienced moral distress, and there was a significant difference in the degree of ethical decision-making confidence according to social positions and experience of ethical education. There were positive correlations between the ethical decision-making confidence and moral sensitivity (r=.382, p<.001) and self-assertiveness (r=.224, p<.01). Regression analysis revealed that the factors that significantly influenced ethical decision-making confidence were moral sensitivity, self-assertiveness and ethical education during nursing practice, which explained 25.0% of variance in ethical decision-making confidence. Therefore, to improve ethical decision-making confidence of nurses, programs should be developed that improve moral sensitivity and self-assertiveness by promoting ethical education.
