In this thesis, I intend to study the translational and clinical interpretation through the syndrom of "Pyong-Yeol-Byong", and reached the following conclusions. 1. Eum-Yang-Kyo (陰陽交)' 1) Meaning: "Eum" means "Essential and vital energy" "Yang" means "Evil factor affecting health" and "Kyo" means "cross-struggle." 2) Location of disease: Heat evil enter Hyeol-Bun (血分) 3) Pathogenesis: Heat evil invade Eum-Bun (陰分) and struggles with Health energy, therefore Eum-Chung (陰精) is exhausted and Heat-evil doesn't disapper, it damage Eum and exhaust fluid. Reach fever, rapid pulse raving and unable to take meal, not controled by sweating and sceach death. 4) Particularity of Syndrome: Heat enter Hyol-Bun, and Evil factor is enough and Health energy is insufficient, so that reveal the symptoms of high fever, delirium with coma, unable to take meals. 5) Therapy: It clears Gi-Bun heat evil (氣分熱邪) by Gypsum, Rhizoma Anemarrhenae, Flos Lonicerae, Fructus Forsythiae, Fructus Gardeniae, Radix Scutellanae Rhizoma Coptidis, and cools Blood by Cornu Rhinoceri Asiatici, Radix Rehmanniae, Cortex Moutan Radicis, Dae-Chung-Yob (大靑葉) Radix Arnebiae Seu Lithospermi. 2. Poong Gweol (風厥) 1) Meaning: Poong means wind-evil, Gweol means reversing up. 2) Location of disease: Disease complexes with TaeYang (太陽) in outer part, and with So-Eum (少陰) in inner part. 3) Pathogenesis: Tae-Yang-Gyeong (太陽經) accept wind-evil and So-Eum-Gyeong (少陽經) Kidney Energy reverse up so that fidgetiness not resolves by sweating. 4) Particularity of Syndrome: There are outer symptoms of fever, hydrosis with inner symptoms of fidgetinessis. 5) Therapy: Reduce Jok-Tae-Yang (足太陽) and Supply Jok-So-Eum (足少陰) by accupuncture, so cure Poong Gweol and make balance between Yeong (營) and Wi (衛). 3. Scrofula coused by wind-evil (勞風) 1) Meaning: It means accepting wind evil rest less. 2) Location of Disease: It locates lung 3) Pathogenesis: Because of accepting wind-evil restless, he take scrofula with damaging lung. 4) Particularity of disease: It is lung disease of aversion to wind and shiver, nape-stiffiness, dim eyesight, cough, disphea, vomitting sputum, if one camnot vomit sputum, he died by damage of lung. 5) Therapy: The period of therapy is different by age or strength of health energy, so I think must prevent Eum deficiency and clear fever no reduced in lung. 4. Shin-Poong (腎風) 1) Meaning: It means taking edema by accepting wind-evil, because the kidney controls water. 2) Location of Disease: It is that wind-evil envade kidney. 3) Pathogenesis : Water evil of kidney with wind-heat rises up to face, reach edema, puffines s of the lower eyelid, floating pulse, bombus, yellowish urine, hydrosis and hand-heating, drymouth and excessive thirsty, walkless by heaviness, menstrual disfunction, restless and unable to take meals, unable to lie flat, heavy cough if lie flat, and accepting wind-evil by deficiency of kidney function, so the function of dredging the water passage is not smooth, symptom of water and symptom of wind reveal together. 4) Therapy: Remove wind-heat, promote diuresis to eliminate tile wetness-evil, supplement the dificiency of kidney's Eum. Finally, we can know that later Fever Disease Medicime (溫病學) is affected to the theory of "Pyong Yeol Byong" in 33th Chapter of SoMoon (素問).

This study was performed to determine the amount of aluminum, which is one of the factors of Alzheimer's disease, In some fishes caught from some areas of the west coast in Korea. The 46 aquatic products were composed of fishes, molluscs, and salt-fermented products (jeot-gal). The 24 fishes were Hickory shad, Gobies, Pomfref, Atkafish, Flounder, Jambeng-ie Monk fish, Yellow hair tail, Mackerel, Bartailed flathead, Alaska pollack, Brown croaker, Eel, Fine-spotted flounder, Black spotted grouper, Sea-eel, Pacific saury, Areliscus honaleus, Small boil-dried anchovy, Croaker, Hair tail, Sea bream genuine, Motleystrip rainbowfish, and Bastard halibut. The 15 Molluscs were Whip-arm octopus, Sea arrow, Common squid, Han chi, Cuttle fish, Turban shell, Pond snail, Orient calm, Surf calm, Butter calm, Crib shell, Oyster, Egg cockle, Little neck calm, and Arkshell. The 7 salt-fermented products were salt-fermented Shrimp, Little neck, Oyster, Shad, Gonjeng-ie, Hqangsegi, and Squid. All of them were ashed with 5$m\ell$ HNO$_3$ and then with 10$m\ell$ ternary solution (HNO$_3$ : H$_2$SO$_4$ : HClO$_4$= 10 : 1 : 4). After ashing of the samples, the aluminum amount were measured by ICP. The aluminum amount of molluscs was significantly higher than that of fishes and salt-fermented products(p＜0.01). The aluminum amount of Orient calm and Healak in molluscs were 827.70, 812.55ppm, respectively, which were the most amounts compared nth that of the other samples. But the aluminum amounts of Bartailed flathead and Sea bream, genuine In fishes were 0.98, 0.97ppm, respectively, which were the least amounts compared with that of other samples. This study was limited within 46 aquatic samples, therefore I hope there will be wider efforts to determine about auminum amount in broade range of aquatic foods for the prevention of Alzheimer's disease.

Field strains of Ornithobacterium rhinotracheale (OR) were tested on their virulence in specific pathogen free (SPF) embryonated chicken eggs and 3-week-old broilers. When infected with three different OR isolates (OR-161, OR-240 and OR-295) through yolk sac infection route, all strains appeared to be highly pathogenic with responsible mortality 66% and 100% within 12 days post infection (DPI). To test the virulence of OR in the commercial broilers, 3 week-old broilers were grouped depends on the inoculation route of OR isolate (OR-295) through five different infection routes; group 1 (IT: intratracheal), group 2 (IM: intramuscular), group 3 (IV: intravenous), group 4 (aerosol) and group 5 [Mixed: NDV (LaSota)+OR aerosol]. Within 5 to 7 days after inoculation, only broilers given NDV+OR were slightly depressed and coughing, and had mild facial redness. Grossly, foamy and yellow-white yogurt like exudate in the air sacs, predominantly in the abdominal air sacs was present. In histology, infiltration of the air sac epithelium and lamina propria by macrophage and polymorphonuclear granulocytes was seen with cell debris and inflammatory cells, correlated with the presence of OR antigen, as demonstrated by immunohistochemistry. Field strains of OR were able to induce high mortality in the embryonated chicken eggs, whereas broilers were less susceptible to OR infection. Interestingly, in the absence of NDV infection, the four groups of OR single infection only different route showed minimal and temporary microscopic air sac lesions. Thus, Newcastle disease virus (LaSota strain) showed triggering effects on the OR infection in chickens.

Root and basal stem rot disease occurred on moth orchid (Phalaenopsis spp.), Pung-nan (Neofinetia falcata) and Nadopung-nan (Aerides japonicum) grown in the farmers' greenhouses located in Namyangju Kyonggi province, Korea during 2005 to 2006. Wilting symptoms occurred on these orchard plants at initial stage and the infected plant leaves turned yellow to red. The discolored leaves were fallen down to lead to eventual death of the entire plant. A total of 59 isolates of Fusarium spp. was obtained from roots and leaf bases of the diseased plants. The cultural and morphological characteristics of isolated Fusairum spp. were identified as Fusarium oxysporum, F. proliferatum and F. solani. F. oxysporum and F. proliferatum were isolated from all these orchard plants but F. solani was isolated only from Phalaenopsis spp. Pathogenicity of the three Fusarium spp. was confirmed by artificial inoculation. Although F. oxysporum, F. proliferatum and F. solani cusing root rot disease in Phalaenopsis spp. have been reported in Korea, the pathogens in N. falcata and A. japonicum were not reported yet. Therefore, this is the first report on the root and stem rot of N. falcata and A. japonicum caused by F. oxysporum and F. proliferatum in Korea.

This study was carried out to breed and develop high quality and functional nutrient tomato with multi disease resistance as well as a stable growing adaptation for fresh market usage under protected plastic houses cultivation. The materials were used 5 inbred lines and their 6 hybrids of large tomato group, which have been bred and developed from 1999 to 2007 in Division of Plant Resource Department of Chungnam National University. Fruit weight showed hybrid vigor effect that $F_1$ hybrids weighed more than their parent lines, fruit shape formed three type of oblate, deep oblate and globe shape, in firmness and pericarp thickness have got a high significant correlation, inbred DN611 line was measured the most firm fruit with 6.04 mm pericarp thickness. In fruit color at maturity, pink color crossed to red color appeared all red fruit color in the $F_1$ hybrids, it means red skin color is a dominant gene compared to pink skin color is a recessive gene in tomato, while between fruit skin color and shoulder part color showed no any co-relationship. The sugar content and titratable acid of $F_1$ hybrids inherited an intermediate data of their parent lines, the flavor of KP543 inbred line and the hybrid (JB535 x KP543) revealed the better taste with high brix and proper titratable acid content$^{*}$. In beta carotene content DN611 line showed 2~3 times higher than other materials so that its 3 hybrids contained an increased level of beta carotene, lycopene content was not so much difference among inbred lines and $F_1$ hybrids, of them MD508 contained higher of 8.72 mg and hybrid (JB535 x JA517) had 8.05 mg lycopene content per 100 g fruit, overall pink skin color and red skin color measured a higher lycopene content than yellow and orange skin color at ripe stage. In disease resistance test by PCR marker for Fusarium race2 (I2), Nematode (Mi1), ToMV ($Tm2^2$), Cladosporium (Cf9), (JB535 x JA517) hybrid have got multi-resistance with homozygote band in Nematode, ToMV, Cladosporium and heterozygote band in Fusarium race2. Through this breeding program we could select high quality and functional nutrient with multi resistant $F_1$ hybrids and inbred lines in tomato which are two best hybrids (JB535 x MD508), (JB535 x JA517), additionally developed high beta carotene inbred line DN611 and increased the level of lycopene inbred line MD508. These results will be very useful to make a high quality tomato variety continuously.

Throughout year 2015 to 2016, 101 proso millet and 200 sorghum samples were collected from five provinces in South Korea. The samples were subjected to paired-end RNA sequencing and further analyzed by RT-PCR. The results indicated that Rice black-streaked dwarf virus (RBSDV) was detected from sorghum collected in Gyeongsang province. The other four viruses, including RBSDV, Rice stripe virus (RSV), Barley virus G (BVG), and Cereal yellow dwarf virus (CYDV), were detected from proso millet. Among four viruses, both RSV and RBSDV were identified high frequency from proso millet collected from Gyeongsang province. Otherwise, BVG was nearly equally identified from five provinces, suggesting that the virus was supposedly widespread nationwide. RBSDV was first identified from both proso millet and sorghum in South Korea. The other virus annotated CYDV identified proso millet was shown to have relatively low identities compared to CYDV previously reported, suggesting that the virus might be new member of Polerovirus.

Among more than 30 viruses infecting strawberry, aphid-transmitted viruses including Strawberry mild yellow edge virus (SMYEV), Strawberry mottle virus (SMoV), Strawberry crinkle virus (SCV), and Strawberry vein banding virus (SVBV) have been considered as the most economically important viruses of strawberry in the world. To determine the incidence of these four viruses in major Korean strawberry cultivars, field surveys were conducted in major production areas during 2018-2019. In our surveys, SMYEV and SMoV were detected with low infection rates of 0.7% and 1.3%, respectively, whereas SCV and SVBV were not detected. No obvious symptoms were observed in the strawberry plants infected by SMYEV or SMoV. Since no sequences of SMoV Korean isolates have been reported, we initially determined nucleotide sequence of the 3' untranslated region (UTR) of seven SMoV isolates obtained during the surveys. The 3' UTR sequences (782 nt) of seven Korean isolates were phylogenetically compared with those of the previously reported SMoV isolates. Phylogenetic analysis revealed that most Korean isolates are closely related to Canadian isolates and only little evolutionary differentiation occurred among the Koreans isolates. This might be due to the low incidence of SMoV in strawberry in Korea.

Most strawberry viruses exist relatively low titers in tissues, and strawberry tissues include high levels of contamination by polysaccharides and phenolic compounds. These traits make the efficiency of strawberry diagnosis difficult. In this study, we tested different commercially available kits and reagents to secure optimal RNA extraction methods to determine virus detection from strawberry leaves. Total RNA was isolated from leaves of strawberry mottle virus (SMoV)-infected strawberry cultivar 'Mihong'. The efficiency of total RNA for virus diagnosis was confirmed through SMoV detection by one-step or two-step reverse transcription and polymerase chain reaction (RT-PCR). Among those, the RNeasy plant RNA kit was best to isolate RNA and the isolated RNA was good enough for further applications. To ensure a reliable detection for strawberry viruses, synthetic diagnosis clones for major seven strawberry viruses such as strawberry mild yellow edge virus, SMoV, strawberry latent ring spot virus, strawberry crinkle virus, strawberry pallidosis associated virus, strawberry vein banding virus and strawberry necrotic spot virus have been constructed. Based on the synthetic genes in each clone, primer sets for seven strawberry viruses were designed and tested an RT-PCR condition through a simultaneous application of the same annealing temperature that allowed to achieve an efficient and convenient diagnosis.

From 1996 to 1999, potato-growing areas in Korea were surveyed for identification and distribution of potato scab pathogens. Potato scab was widely distributed in the mass cultivation areas, especially in Jriu island, southern areas of Chonnam and Gyounggi provinces, and the alpine area of Gangwon province. Jeju island was the most affected area by this disease. A total of 55 Streptomyces strains were isolated from potato scab lesions, among which 40 strains were pathogenic on progeny tubers. Among the pathogenic strain, 21 strains were identified as previously described S. scabies, 7 Strains as S. turgidiscabies, and 5 Strains as S. acidiscabies, while 7 strains were observed as having distinct phenotypic properties. These strains were classified into six distinct clusters based on phenotypic characteristics and selected representative strains for each cluster. S. scabies (S33) had grey spores in a spiral chain. Mean-while, S. turgidiscabies (S27) had grey spores, S. acidiscabies (S71) had white spores, S. luridiscabiei (S63) had yellow-white spores, S. puniciscabiei (S77) had purple-red spores, and S. niveiscabiei (S78) had thin and compact white spores, all in a rectiflexuous chain. Pathogenicity was determined by the production of thaxtomin A and homologs of necl and ORFtnp genes. In TLC, representative strains S27, S71, S63, S77, and S78 produced a yellow band that co-migrated with the authentic thaxtomin A. However, thaxtomin A was not detected in chloroform extracts from oatmeal broth culture and Slice tuber tissue of S. luridiscabiei (S63) and S. puniciscabiei (S77) by HPLC analysis. In addition, no homologs of necl and ORFtnp genes in S. acidiscabies (S71), S. luridiscabiei (S63), S. puniciscabiei (S77), and S. niveiscabiei (S78) were detected by PCR and Southern hybridization analysis.
