Nan Jing(Difficult Classic), as a catechism, describes in detail and deeply the ideas in Nei Jing(Huangdi's Internal Classic). The description of Nan Jing is focused on basic theories including theories about some disease and is excellent in identification and analysis. The contents of Nan Jing are as follows: 1-23 Nan-pulse and pulse condition, 24~29 Nan-channels and collaterals, 30~47 Nan-viscera and bowels(Zang Fu organs), 48~61 Nan-disease, 62~68 Nan-acupuncture points, 69~91 Nan-acupuncture. Especially, diagnosis techniques in Nan Jing make 'Only method of cunkou pulse taking' that is a technique for feeling the pulse widely applied in these days in Oriental medicine clear. Thus, this book adjusts the theory of pulse and pulse condition given in 1~23 Nan of 'The Study of Nan Jing' in order to enhance an understanding about the theory of pulse and pulse condition. The text of 1~23 Nan about pulse lore centers on all pulse of human body interconnected each other and cunkou, both ends of the pulse, and contrasts regular pulse with irregular pulse. 1. 10 Nan describes the theory about five kinds of evils and hardness and softness, and unique pulse condition of each bowels. 2. 13 Nan explains that the relative difficulty of medical treatment is determined by the degree of balance or unbalance among three factors-colors, pulse and pulse condition, flesh shape. 3. 14 Nan divides pulse and pulse condition into slow pulse and rapid pulse, and explains separately abnormality, great loss of semen, death caused by slow pulse, and abnormality, great loss of semen, death caused by rapid pulse. 4. 15 Nan about taut pulse(弦), full pulse(鉤), floating pulse(毛), deep pulse(石脈) describes that pulse and pulse condition differs according to four seasons. Therefore, Nan Jing establishes clearly techniques of feeling the pulse in 'Only method of cunkou pulse taking(獨取寸口)' and advances the theory of Nei Jing. Futhermore, Nan Jing is more valuable in that it suggests unique theory different with Nei Jing.

In order to presume the relationships between two species of P. ternata and P. tripartia, and their populations of the Korean Pinellia, RAPD analysis was performed. The length of the amplified DNA fragments ranged from 300 to 2,500bp. Seventy scorable RAPD makers were found from the PCR reactions with 7 random oligoprimers and were analyzed by Nei-Li's genetic coefficient. Also, some regional groups instead of same taxa were clustered from the phenogram of UPGMA analysis and NJ tree. Populations within each species were clustered at low genetic distance, there had the closed relationship. According to the regional individuals, Pinellia ternata was showed the variation pattern of morphological (leaf shape and flower color) and cytological characters(somatic chromosome numbers). So we suggested to difference of characteristic variety based on variety of habitat. According to this study, new species (Pinellia sp.) was affiliated with Pinellia and had the closest relationship with Hallasan and Japan population. The RAPD data was very useful to define the genetic variation and to discuss the relationships among the intraspecific taxa and their populations of the Korean Pinellia.

Agastache rugosa, a member of the mint family (Labiatae), is a perennial herb widely distributed in East Asian countries. It is used in traditional medicine for the treatment of cholera, vomiting, and miasma. This study assessed the genetic diversity and population structures on 65 accessions of Korean mint A. rugosa germplasm based on inter simple sequence repeat (ISSR) markers. The selected nine ISSR primers produced reproducible polymorphic banding patterns. In total, 126 bands were scored; 119 (94.4%) were polymorphic. The number of bands generated per primer varied from 7 to 18. A minimum of seven bands was generated by primer 874, while a maximum of 18 bands was generated by the primer 844. Six primers (815, 826, 835, 844, 868, and 874) generated 100% polymorphic bands. This was supported by other parameters such as total gene diversity ($H_T$) values, which ranged from 0.112 to 0.330 with a mean of 0.218. The effective number of alleles ($N_E$) ranged from 1.174 to 1.486 with a mean value of 1.351. Nei's genetic diversity (H) mean value was 0.218, and Shannon's information index (I) mean value was 0.343. The high values for total gene diversity, effective number of alleles, Nei's genetic diversity, and Shannon's information index indicated substantial variations within the population. Cluster analysis showed characteristic grouping, which is not in accordance with their geographical affiliation. The implications of the results of this study in developing a strategy for the conservation and breeding of A. rugosa and other medicinal plant germplasm are discussed.

A taxonomic study of Viola albida complex, containing the representative individuals of three taxa, V. albida var. albida, V. albida var. chaerophylloides, and V. albida var. takahashii, was done based on RAPD data. The amplified loci were 476 in total; obtained with 68 universal primers on seven OTUs. Nei's genetic dissimilarity appeared relatively low within individuals of V. albida var. albida and V. albida var. chaerophylloides (0.118-0.171 and 0.051 respectively), however, it was higher in individuals of V. albida var. takahashii (0.348). On the other hand, there is no specific trend in terms of genetic dissimilartiy among taxa, such as between individuals of V. albida var. albida and V. albida var. takahashii, between those of V. albida var. albida and V. albida var. chaerophylloides, and between those of V. albida var. albida and V. albida var. takahashii. The similarity of OTUs studied is high in clustering analysis, so that this result is compatible with the establishment of this complex. All OTUs are clustered within two groups. The individuals of V. albida var. takahashii, however, are clustered both to the group of V. albida var. albida and to the group of V. albida var. chaerophylloides, meaning that the genetic difference is high which would be commensurate with their morphological variations.

A genetic variation within 29 strains of F. velutipes was analyzed by internal transcribed spacer (ITS) sequence analysis and random amplified polymorphic DNA (RAPD). Seven hundred and twenty base pairs were sequenced during the analysis of the ITS region, but no significant variation was observed among the 29 strains of F. velutipes. Sixteen out of 40 random primers amplified polymorphic RAPD fragment patterns. The polymorphic levels of RAPD bands by some primers (OPA-2,4,3,9,10,20) were very high in all 29 strains, with 3,030 fragments ranging between 200 and 2,000 bp. Intraspecific genetic dissimilarity of the 29 strains was calculated to range from 3.3% to 45% by Nei-Li's method using these 3,030 RAPD bands. The genetic variation among Korean strains was relatively high, with dissimilarities ranging between 17% and 38.6%. In the Neighbor-Joining analysis using the genetic dissimilarities based on RAPD, all 29 strains were classified into 5 clusters. Strains in each cluster showed specific characteristics according to their origin and strains. These results suggested that OPA and OPB primers could be used for developing molecular genetic markers and screening of unidentified (F. velutipes) strains.

Along with the development of telecommunication technology, educational role has been considerably changed and NEIS is introduced and operated for the digital educational administration. However, the function of NEIS is so limited when operated in each school. As a result, Korean government prepares the plan to install and operate a new School Affairs System by separating 3 areas from 27 areas of NEIS. School Affairs System has been used in schools since March, 2006. In this regard, this study attempts to analyze the current status and tasks of using the system in elementary schools. The result of the study shows that about 67% teachers use the system once or twice a day. Most of teachers answer that they get help from other teachers if they have any problem in operating the system. Many teachers affirmatively answer to the design and function of the system, and they are satisfied with the convenience and efficiency of the system. However, they feel difficulty to be familiar with the system sue to the frequent change. The importance of electronic certificate and personal information is well recognized and managed in terms of the security of the system. Facilities need to be well equipped, and information exchange system need to be developed to accept each school's request to improve the function of the system. In addition, applicable laws need to be arranged, clear guideline of educational administration agency and principal's strong intention are required to relieve teachers' work load.

In this paper, the behavior of nuclear-power plant subjected to an aircraft impact is performed using the parallel analysis. In the erstwhile study of an aircraft impact to the nuclear-power plant, it has been used that the impact load is applied at the local area by using the impact load-time history function of Riera, and the target structures have been restricted to the simple RC(Reinforced Concrete) walls or RC buildings. However, in this paper, the analysis of an aircraft impact is performed by using a real aircraft model similar to the Boeing 767 and a fictitious nuclear-power plant similar to the real structure, and an aircraft model is verified by comparing the generated history of the aircraft crash against the rigid target with another history by using the Riera's function which is allowable in the impact evaluation guide, NEI07-13(2009). Also, in general, it is required too much time for the hypervelocity impact analysis due to the contact problems between two or more adjacent physical bodies and the high nonlinearity causing dynamic large deformation, so there is a limitation with a single CPU alone to deal with these problems effectively. Therefore, in this paper, Message-Passing MIMD type of parallel analysis is performed by using self-constructed Linux-Cluster system to improve the computational efficiency, and in order to evaluate the parallel performance, the four cases of analysis, i.e. plain concrete, reinforced concrete, reinforced concrete with bonded containment liner plate, steel-plate concrete structure, are performed and discussed.

The partial sequences of mtDNA cytochrome b gene in two subspecies of striped field mouse(Apodemus agrarius coreae and A. agrarius manchuricus) from Korea and northeast China were analyzed to determine the degree of genetic diversity in ech subspecies and to confirm their subspecific difference. In 18 specimens of A. agrarius coreae, ten haplotypes were resulted, and in two specimens of A. agrarius manchuricus. one haplotype was revealed. Tamura-Nei nucleotide distance among ten haplotypes in subspecies coreae ranged 0.36 to 1.86%. and nucleotide distance between two subspecies (coreae and manchuricus) was 0.37 to 1.47%: maximum infrasubspecific divergence in coreae was greater than maximum intersubspecific difference between two subspecies. Moreover, no major subgroup was resulted when 11 haplotypes in two subspecies were compared. Our sequence result was not cancordant with the morphological data studied so far, and it is concluded that cytochrome b gene sequence is not a good genetic marker to distinguish two subspecies of A. agrarius. In futurem, mtDNA control region analyses seemded to be necessary to reveal genetic relationship between these two subspecies of A. agrarius.

This research was carried out to evaluate whether gamma ray is a useful tool for breeding new strains of mushrooms. For this research, 5 mutant groups, 20 strains of Hypsizigus marmoreus, 2 strains of Lyophyllum decastes, and 1 strain of Lyophyllum shimeji were used. Monokaryon spores from one variety of H. marmoreus were irradiated with 50~2,000 Gy of gamma ray. The propriety dose was 50~200 Gy for mutagenesis. Mutant monokaryon mycelia crossed each order to become dikaryon mycelia. The internal transcribed spacer (ITS) regions of rDNA were amplified using PCR, and the products were sequenced. The sequences of the ITS regions (16 partial rDNA, complete ITS1, 5.8 rDNA and partial rDNA) were analyzed by PCR, and strains of H. marmoreus, L. decastes, and L. shimeji were auto-sequenced. The lengths of the sequenced ITSs were 1,052~1,143 nucleotides. Genetic matrices were calculated using Nei-Li's genetic distance coefficient based on ITS sequence. The dissimilarities were 0~3.35% in strains of H. Hypsizigus. In addition, a phylogenetic tree was constructed based on ITS sequences using the neighbor-joining (NJ) method. The phylogenetic tree revealed that 23 strains and 5 mutant groups were divided into 12 clusters; the mutant groups fell into different clusters. These results show that mushroom spores were mutated effectively by gamma ray; therefore, gamma ray could be a useful tool for breeding new strains of mushrooms.

The National Education Information System (NEIS), one of ERP systems developed by Ministry of Education & Human Resources Development, has been utilized in primary and secondary schools. In this paper, we considered the NEIS should be used not only for educational administration affairs, but also for a lifelong management of National Human Resource. The current School Information Management System (SIMS) is unsatisfactory due to the insufficiency of actual field suitability and user's conveniency. For solving such problems, the system rebuilding or revision should be accompanied by. As a guideline of revision and supplement of the SIMS, we suggest an application useful in both schools and clinics by the integrating healthcare management information of people. For this, we propose a lifelong healthcare information management by integrating Student Health Records of the NEIS with Electronic Medical Records of doctors' offices. The healthcare information is designed and represented in XML. We applied different XSL style-sheets to XML documents in order to offer a view suitable for demands of schools and clinics. The healthcare information can be managed and utilized efficiently by using the view. We ascertained that the lifelong Healthcare Information Management System is an improvement to overcome the inefficiency of healthcare information management and the connection inadequacy between schools and medical institutions, and is desirable for a lifelong management of the National Human Resource.
