The purpose of this study is to consider practical examples of the method of utilizing plant material 'lotus' used by the ancients, and the value and meaning they wanted to get from it. The method of this study to do this is descriptive study to consider and interpret poem and painting reflecting impression and concept world of lotus. Summary of this study is as follows. First, ornamental value of lotus could be divided in effect of group plant and detail value held by the flower, the leaves and the stem. Especially, group plant lotus in large site provides unique landscape differentiated form other flowering plants. As well, another feature of lotus is its high ornamental value spread in detail elements including the flower, the leaves, the stem and the lotus seed. Second, fragrance expressed 'Hyang-won-ik-cheong(香遠益淸)' is an important charm of lotus. Lotus was utilized as olfactory element providing fragrance. The ancients considered lotus fragrance not only for enjoy but as symbolic object comparing noble man's dignity so that they expressed it in poem and painting. Third, lotus was utilized as acoustical element. That is, the sound of raindrops harmonizing the surface of water and wide lotus leaves was called 'hearing lotus fond and rain', enjoying it as classic grace. Fourth, summer play lotus sightseeing was called mind wash up meaning 'washing the mind polluted by the mundane world'. Such poetic taste was widely enjoyed by various classes from general public to royal family. Besides, poetic taste related with lotus is the method of drinking alcohol using the feature of big lotus leave and vacant stem, called 'Beog-tong-ju(碧筒酒)'. And in the Joseon dynasty period, when the distinction between the man and the woman influenced by Confucian, lotus seed and 'lotus collecting song' was important sign to express romance between man and woman. Lotus has been enamored by wide classes transcending cultural background as thought and religion since ancient times. Due to such reasons, various symbolic meaning of lotus and planting examples related to religious facilities as temples could not be considered in various manner is limitation of this study, and which is research project for the future.

KIT encodes a mast/stem cell growth factor receptor and is known as a possible candidate gene responsible for dominant white coat color in mammals. To investigate the genetic variation of KIT gene in Korean wild boars(Sus scrofa coreanus), we carried out PCR-RFLP and DNA sequencing for three exons(exons 17, 19, and 20) and intron 19 of the KIT gene in Korean wild boars. PCR-RFLP results using NlaⅢ restriction enzyme in the breakpoint region between exon 17 and intron 17 and AciⅠ restriction enzyme in exon 19 indicate that Korean wild boars did not have previously identified white coat color related splicing mutation and missense mutation, respectively. These results also indicate matings between Korean wild boars could not give white coat color offsprings. We also found new SNPs in exons 19(C2661T) and 20(A2760G). Of these, the SNP in exon 20 is a missense mutation which might induce the change of amino acid iso-leucine to valine. However, no relationship was identified with this missense mutation and coat color. In this study, breed specific new SNPs were identified in exons 19, 20 and intron 19 and these results will give important information for genetic variation of porcine KIT gene.

This study aims to provide policy suggestions by examining the perception and attitude of Koreans toward the welfare rights. The study was done through a telephone survey conducted by an opinion research institute on 2,050 respondents in 16 cities and provinces. The results are as follows. First, a majority of Koreans responded that the primary responsibility for welfare rests with the government and perceived their welfare receipt rights in a positive way. Respondents also showed an assertive attitude toward exercising their rights by stating that they intend to file a demurrer or participate in civic activities. Second, in terms of duty performance, most respondents showed different positions concerning tax hike and insurance rate increase, although they showed a stronger opposition to an increase in insurance fee. In addition, 90% of the respondents were in favor of building welfare institutions in the residential area and an overwhelming proportion of the respondents indicated that they would take an active part in welfare development by regularly paying taxes and volunteering. Third, the respondents gave a very negative rating to Koreas welfare system and its overall level. That is, people thought that the level of Koreas welfare system is on a par with that in developing or underdeveloped countries, and that the welfare system benefits no one or only the rich. People generally felt that there was not one proper welfare institution. In conclusion, the study found that Koreans have keen awareness of their welfare rights and proactive attitude toward welfare development, whereas negative viewpoint toward tax and insurance fee increases. This may stem from peoples distrust of government welfare policies and the existing welfare system. This study suggests that welfare policy is an important factor in determining peoples political attitude. Therefore, government authorities must recognize people not as passive receivers of welfare benefit but as active policy partners, and establish policies that reflect peoples high welfare rights perception and willingness to take part in welfare development.

This study was carried out to improve the forest management method considering the use of high value added timber in the natural broadleaf forests. For this purpose, the criteria for evaluating the quality grade of standing trees were established and applied to the oak stand in the central region of Korea. The evaluation factors of the grade were bending of stem, branch, stem damage, and other defects. If the logs are divided into 2.1 m units and three logs up to 6.3 m are available, they are classified as Grade I (G-I). If two logs are available, they are classified as Grade II (G-II), If only one log is available, it is classified as Grade III (G-III). When any log is not available as timber, it is classified as Grade IV (G-IV). As a result of applying the grade to the oak stand, G-I was 6.7 %, G-II was 28.0 %, G-III was 38.3 %, and G-IV was 27.0 %. The ratio of standing trees by oak species of higher than G-III was 88.2 % for Quercus acutissima, 88.1 % for Q. variabilis, 83.5 % for Q. serrata, 56.3 % for Q. aliena, and 50.3 % for Q. mongolica, respectively. The G-IV ratio for Q. variabilis and Q. mongolica tended to decrease with increasing diameter at breast height. The order of major defect affecting the grading level was bending of stem > branch > stem damage > other defects. Considering the grade level and oak species distribution, it was concluded possible to produce high quality hardwood timber when we concentrate forest tending techniques on Q. acutissima and Q. variabilis stand. In order to improve the accuracy of grading, it is necessary to continuous complement through the monitoring research for evaluation factors.

The purpose of this study is to define the key competency as Christian(in another word: Christian key competency) and to interpret the six key competencies of the 2015 revised curriculum in a Christian educational way. Also as an alternative to the key competencies model of the 2015 revised curriculum, this study aims to materialize the formation of a Christian key competencies model based on Christian faith. This study derived 'faith' from the key competencies as Christian throughout preceding research analysis. The 'faith' of the key competencies as Christian means the ability to know oneself, and to know the world and God within the knowledge of the Bible (knowledge of God) in the personal relationship with God, and also it is the ability to think, judge, and act with biblical values, Christian world view, and Christian self-identity. The key competency 'faith' could be the basis (standard) of motivation, attitude and the value of all competencies in cultivation and exercise. The model of Christian key competencies has the structure in which each six key competencies become to be cultivated based on the Christian key competency called "faith." Based on the structure, the six key competencies of the 2015 revised curriculum were interpreted and explained from the perspective of Christian education. In the self-management competency, self-identity can be correctly formed in relations with transcendent God. In aesthetic emotional competency, the empathic understanding of human beings comes from the understanding of the image of God, the supreme beauty, the source of beauty. About the community competency, human community is the source of God who created the universe, human and all of things. It is because a Christian community is a community within the relationship of Trinity God, Nature and others. Therefore regions, countries, and the world become one community. Communication competency first stem from good attitudes toward yourself and others with respectful mind. It comes from an understanding of Christian human beings. Also, there is a need of having a common language for communications. The common language is the Bible that given to us for our communicative companionship. Through the language of the Bible, God made us to know about God, human being and the creative world, and also made us to continue to communicate with God, others and the world. For having the knowledge-information processing competency, a standard of value for the processing and utilization of knowledge and information is required. The standard should be the basis of moral and ethical values for human respect. About creative thinking competency, the source of creativity is God who created the world. Human beings who have the image of God own creative potential. As well as, creativity has different expression forms depending on individual preferences and interests, and different approaches will be made depending on each individual's importance and achievement. Individual creativity can be found through education, and it can be embodied by converging knowledge, skills and experience.

We experienced a case of cerebral hypoperfusion due to cyclosporine neurotoxocity confirmed only by Tc-99m ECD brain SPECT. A 53-year-old female had received allogenic peripheral blood stem cell transplantation due to refractory plasmacytoid lymphoma. Cyclosporine and steroid had been administrated to prevent graft versus host disease. Twenty days after transplantation, she became delirious and suffered from generalized tonic-clonic seizure. Immediately, brain MRI and MR angiography were performed and these studies did not show any abnormal findings. However, Tc-99m ECD brain SPECT showed diffuse hypoperfusion in the left cerebral hemisphere and blood cyclosporine level was 962.6 ng/ml. Cyclosporine administration was stopped and discontinuation of cyclosporine resulted in disappearance of all neurological symptoms. The same neurological symptoms recurred with cyclosporine re-administration for management of exacerbated graft versus host disease. In this case, Tc-99m ECD brain SPECT proved very helpful in the diagnosis of cycloporine neurotoxicity.

The Polygonatum spp. used in this study was collected from 1994 to 1997, and planted by species in Hamyang medicinal plant experimental station field. $30{\sim}40 $ species of Polygonatum spp. have been known to be distributed in the northern hemisphere, and $14{\sim}18$ species in Korea. In this study, collected seven species of Polygonatum spp. were investigated. Plant height was highest in Polygonatum stenophyllum followed by P. falcatum, P. humile, P. lasianthum var. coreanum.. Leaf length was longest in P. falcatum and shortest in P. odoratum and leaf width was the most wide in P. odoratum var. pluriflorum. P. stenophyllum had 111 flowers per stem. The other species had $14{\sim}22$ flowers per stem. The ratio of flower setting in each species was high at two but was 95.2% at above four in P. stenophyllum. The number of fruits was 14.8, 15.4 and 17.7 in P. odoratum, P. falcatum and P. humile, respectively. Other species did not produce fruit. Fruit setting percentage was high in P. odoratum as 81.5%. The number of branched rhizome doubled every year.

We studied the effect of fermented Rhus verniciflua stem bark (FRVSB) extract (used in herbal med-icine by Koreans) on the microbial growth and enzyme activity of 12 soybean-fermenting microorganisms, including Bacillus spp., lactic acid bacteria, yeast, and other harmful bacteria. The ethanol and methanol extracts of FRVSB inhibited the growth of Bacillus subtilis, Bacillus licheniformis, Bacillus cereus, and Zygosaccharomyces rouxii, and in the disk diffusion assay, their inhibition zone diameters were 11.06-12.23, 12.32-18.38, 11.47-11.84, and 13.59-14.21 mm, respectively. The water extract did not show any inhibitory effect. In fact, the water extract addition enhanced the growth of B. subtilis and B. licheniformis by 1.3-4.5 fold and that of B. cereus by 1.2-1.4 fold. However, the water extract did not affect the growth of Lactobacillus plantarum, Lactobacillus mesenteroides, Saccharomyces cer-evisiae, and Escherichia coli. The addition of water extract increased the amylase and protease activity of B. subtilis and B. licheniformis.

Objective : Major depression is known to have immunologic dysfunctions, the recent studies revealed that cytokines including IL-6 and IL-$1{\beta}$ were increased in patients with major depression. Since molecular genetic methods have been progressed, this study was to investigate the relationship between major depression and immunologic aspects by analyzing polymorphism of IL-10 gene. Method : 92 patients with major depression were included and data of 146 normal controls obtained from the Catholic Hemopoietic Stem Cell Information Bank of Korea were used in this study. DNA was extracted from whole blood, thereafter amplified by polymerase chain reaction, and digested by Mae III After that procedure, we obtained and assessed RFLP of two alleles, IL-10T and IL-10C. All data were analyzed by ${\chi}^2$ test. Results : 1) There were no significant difference in genotype frequencies of $IL-10^*T/T$, $IL-10^*T/C$, and $IL-10^*C/C$ between major depression patients group and control group. 2) There were no significant difference in allelic frequencies of $IL-10^*T$ and $IL-10^*C$ between major depression patients group and control group. Conclusion : We did not verified the differences in frequencies of $IL-10^*T/^*IL-10^*C$ gene between the major depression patients group and control group, respectively. But the results of this study do not declare that the IL-10 gene has no association with major depression. We do suggest that further systematic studies including various clinical variables should be conducted.

Solid and papillary epithelial neoplasm of the pancreas is an uncommon low-grade malignant tumor found predominantly in young females. It is rare in childhood. The origin of the tumor is probably from a multipotential stem cell of the pancreas. Neoplasm usually behave like a very low grade malignancy, so that complete removal is the treatment of choice for the tumor arising anywhere in the pancreas. We report a case of solid and papillary epithelial neoplasm of the pancreas in a 14 year -old girl who presented with intermittent abdominal pain and abdominal mass. CT scan shows a large, about $7{\times}6\;cm$ sized, well-marginated hypodense round mass in the head of the pancreas with some ill defined enhancing solid internal portion. She had taken complete excision of the pancereatic mass and Roux-en-Y pancreaticojejunostomy and histologically comfirmed solid and papillary epithelial neoplasm of the pancreas. A brief review of literature was made.
