Tomato spotted wilt virus (TSWV) occurred abruptly with a high incidence rate in 14 vegetable crops in Anyang area, Gyunggido in 2004. TSWV was identified by the symptoms on the indicator plants, immunocaptured reverse transcription-polymerase chain reaction (IC/RT-PCR), virion captured (VC)RT-PCR and RT-PCR using total RNA from the infected plants. Vegetable crops infected with TSWV included table tomato, cherry tomato, red pepper, lettuce, chicory, red leaf chicory, red mustard, dragon tongue, treviso, potato, perilla, sesame, pumpkin, and ssamchoo (hybrid of oriental cabbage and cabbage). The incidence of TSWV in fields ranged from 30 to $100\%$. TSWV usually produced necrosis, wilt and/or severe mosaic with typical single or double ring spots on the leaves. TSWV could be detected in Frankliniella occidentalis collected from the crops in the fields with $90\%$ rate by IC/RT-PCR.

Verdicts related to major medical litigation given by the Seoul Central District Court, the Seoul High Court and the Supreme Court in 2010 were analyzed. It's shown that in cases of the medical negligence regarding the occurrence of neonatal cerebral palsy, the plaintiff claims were dismissed using criteria proposed by associations of Obstetrics and Gynecology and Pediatrics in US, and thereof the burden of plaintiffs to prove the medical negligence has increased. In addition, in case of that the expected survival period of infants gets longer, payments for treatment and nursing after survival period determined by judges are made and it was judged to compensate it as a periodical indemnity. In case for the explanation obligation the most frequently mentioned in the medical litigation, in addition to cases of invoking the existing theory of explanation obligation, verdicts to mention the instructions of theory regarding instruction explanation obligation and the possibility of compensation for damages on property are given. Particularly, in cases for a liability of reparation by exaggerating the effects and not disclosing the risks related to treatment with stem cells, even if the treatment not approved by Food and Drug Administration is in violation of the Pharmaceutical Affairs Law, it's not illegal as violation in Pharmaceutical Affairs Law itself. But there is a certain verdict to present the possibility of an extension of the theory of explanation obligation by acknowledging the liability of reparation caused by illegal acts with no explanations of effects and risks of treatment with stem cell by doctors and pharmaceutical companies. In an incident in which a mental patient fell and died through the opened door of the roof at the hospital, a liability of reparation was acknowledged due to defects in structure installation management and this verdict drew an attention since the overall management responsibility about patients including structures was acknowledged to the hospital besides the obligations on medical practice. In case of the verdict without giving the opportunity to state the opinion with respect to the main legal issues, the responsibility of the court was emphasized since the court did not fulfill the explanation obligations. There were some cases in which payments for nursing and caring to a patient in vegetative state during the plastic surgery was admitted. However, in dental-related incidents, the proportion of cases in which plaintiff won was low since the difficulty of proving may be reflected. In the area of administrative litigation, unlike the existing position regarding arbitrary medical charge cover collected from patients in hospital, the verdict to admit the legitimacy of collection of medical treatment was given and attracted the attention of people. Verdict in which the expression related to medical advertisement was not exaggerated disposed the original verdict and pointed out the problem of excessive regulations on medical advertisement. The effort to analyze the trend of verdicts of court through reviewing the decisions and to organize should be continued, but the full decision should be disclosed as a base, and people and systems to enable the all time monitoring should be prepared.

Various interpretations on the boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system, and on the geologic structure and stratigraphy of the $Okch{\check{o}}n$ system have been yielded by the previous studies, and they are still in hot debate. The present work has mainly studied on the boundary between the $Okch{\check{o}}n$ and $Chos{\check{o}}n$ systems in the south of $Jech{\check{o}}n$, and the geology in its vicinity to clarify the previous misinterpretations if any on the geologic structure and in trun stratigraphy of the area concerned. The boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system has been thought to be (1) gradational relation which means two systems are the same formation, (2) unconformable relation in which the $Okch{\check{o}}n$ system overlies the $Chos{\check{o}}n$ system, (3) unconformable relation in which the $Chos{\check{o}}n$ system overlies the Okchon system indicating that the age of the $Okch{\check{o}}n$ system is Precambrian, and (4) fault contact in which the $Okch{\check{o}}n$ system of Precambrian age comes in contact with the $Chos{\check{o}}n$ system of Cambro-Ordovician age. The present study clearly found that the relationship between the two systems is a fault zone contact. Shear zone of a width of 300 to 400m is developed, and andesitic volcanics and basic dikes are intruded along the fault zone. This fault contact is exactly the north extension of the Bonghwajae fault, which was denominated long time ago by two of the present authors. The eastern side of the fault has been uplifted so that the $S{\check{o}}changri$ formation of the $Okch{\check{o}}n$ system cropped out in the zone of the Great Limestone series. All the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, but the present study found an overthrust having a strike of $N8^{\circ}E$ and dip of $30^{\circ}NW$ between them, and the $S{\check{o}}changri$ formation has thrusted over the Great Limestone series at the central part of the study area. In the southern and northern parts of this uplifted $S{\check{o}}changri$ formation, the Great Limestone series rests unconformably on it. In the eastern part of the study area where the Mt. Dangdu is located and the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, Precambrian basement rock whose age is older than 1720+50 m.y. crops out in the northern part of the east-west trending high angle fault, and the Great Limestone series rests unconformably on the basement.

Petrological, paleomagnetic, geomorphological and structural studies on the southern part of, so called, Chugaryeong rift valley, have been carried out in order to clarify the nature of the rift valley. Three stages of volcanic activities characterized by Jijangbong acidic volcanic rocks and tholeiitic and andesitic basalt of Cretaceous age(?), and Jongok Quaternary olivine basalt occurred along the Dongducheon fault line. Jijangbong acidic volcanic rocks distributed in the central part of the studied area consist of rhyodacite, acidic tuff and tuff breccia, which are bounded by Dongsong fault on the east and Daegwangri fault on the west. The Jongok basalt differs from those of Ulrung and Jeju islands in mineralogy, chemical composition and differentiation. Jongok basalt distributed along the Hantan river dilineates the vesicles curved toward downstream direction and increment of numbers and thickness of lava flow toward upstream direction. These facts suggest that lava flowed from upstream side of the river. Rectangular drainage patterns also support the presence of the Dongducheon, Pocheon, Wangsukcheon and Kyonggang faults which were previously known. LANDSAT image, however, does not show any lineaments which could be counted as a graben or rift valley. Displacement of Precambrian quartzite and Jurassic Daedong supergroup along the southwestern extension of the Dongducheon fault shows the right lateral movement. The Paleomagnetic study of the tholeiitic and andesitic basalts from Baegeuri, Jangtanri and Tonghyeonri located at 2. 3km east, 0km east, and 1.5km west of Dongducheon fault respectively shows that their VGP(Virtual Geomagnetic Pole) being to intermediate geomagnetic field of short duration which suggests that they formed in almost same period. Mean VGP of Jongok basalt is located 82.4N and 80.6E. This is in good coincidence with worldwide VGP of Plio-Pleistocene indicating that Jongok basalt was extruded during Plio-Pleistocene epoch, and suggesting that the studied area has been tectonically stable since then. From the present study, the tectonic episode of the region is concluded as following three stages. 1. The 1st period is worked by the Daebo orogeny of Jurassic during which granodiorite was intruded in Precambrian basement. 2. The 2nd period is the time when right lateral strike-slip fault of NNE-SSW direction was formed probably during late Cretaceous to Paleogene and the Jijangbong acidic volcanic rocks and the older basalts were extruded. 3. The 3rd period is the time when the fault was rejuvenated during Pliocene or Pleistocene accompanied by the eruption of Jongok basalt. As a conclusion, geologic structure of the studied area is rather fault line valley than graben or rift valley, which is formed by differential erosion along the Dongducheon fault suggesting a continuation of the Sikhote-Alin fault. The volcanic rocks including the Jijangbong acidic rocks, tholeiitic-andesitic basalt and olivine basalt are associated with this fault line.

Thyroid carcinoma ranks low in incidence and as a cause of death when compared to carcinomas arising in the other site. With adequate surgical treatment, the prognosis of operable thyroid carcinoma is good. However, the extent of surgical resection in treatment of thyroid cancer remains still controversy. The aim of this study was to assess the results of thyroid cancer patients treated surgically and to analyze the prognostic factors affecting survival and to improve the survival rate. We retrospectively analyzed the outcome of a total of 278 thyroid cancer patients treated surgically at Inje University Paik Hospital from 1980 to 1995 and followed for 1 to 16 years. There were man in 47 and woman in 231 patients with age range of 14 to 79 years(mean 42 years). Histopathologic findings were papillary carcinoma in 233, follicular carcinoma in 33, mixed carcinoma in 7, medullary carcinoma in 2, and undifferentiated carcinoma in 3 patients, respectively. Operative procedures were unilateral lobectomy in 111, subtotal thyroidectomy in 100, and total thyroidectomy in 67 patients. Central node dissection was performed in 92, modified neck disseciton in 62, radical neck dissection in 28, and no node dissection in 96 patients. Thyroid hormone was administered for the period of 3 to 5 years to suppress endogenous TSH production. Overall 5-year survival rate according to Kaplan-Meier method was 91.1%. Independently, significant factors affecting the prognosis were age at diagnosis, tumor size, pathologic type, tumor stage, lymph node metastasis, angioinvasion, extrathyroidal extension, and 'risk' group category. but, the prognosis were not influenced by sex and capsular invasion. Patients at low risk or with small size carcinomas had long survival over 5 years with only lobectomy. Lymph node dissection was carried out with a limited type in no jugular metastasis, radical neck dissection was performed only therapeutically in proved jugular node metastasis. Fifteen patients were dead of tumor recurrence after surviving for three months to two and half years, and the cause of death was local recurrence in nine, bone metastasis in four and lung metastasis in two patients. In conclusion, more extensive surgery including total thyroidecotmy and systematic compartment-oriented dissection of the lymph node metastases in patient at high-risk group will results in better survival and lower recurrence rate.

In this study, the optimum conditions were established for anthocyanidin extraction from sweet potato tips and tubers. The dependent variables of ethanol concentration (X1), citric acid concentration (X2), and extraction temperature (X3) were designed using a central composite design. All three variables significantly affected anthocyanidin extraction, and the influence of X1 was greater than that of X2 and X3. The highest anthocyanidin content in tips and tubers were 26.58±0.07 and 117.32±0.39 mg/100 g at 50% (X1), 0.3% (X2), and 50℃ (X3), respectively. The optimal extraction conditions for the tips were 56.10% (X1), 0.25% (X2), and 52.24℃ (X3) and tubers were 55.08% (X1), 0.30% (X2), and 53.06℃ (X3). The predicted values under optimal extraction conditions were 27.45 and 119.61 mg/100 g, and the experimental values were 27.09±0.11 and 118.72±0.67 mg/100 g, respectively. The extraction conditions were validated by comparing the predicted and actual values with those of 98.69 and 99.26%, respectively.

Animation is an important tool to establish the identity of mutually related countries, as cultural contents with the economic value. That is, it is necessary that the Korean animation should extend the previous boundary of exchange, for the status of representative cultural industry in the 21st century global market. Especially, to overcome the regionally prejudiced and unbalanced cultural exchange, the possibility of extension with Czech animation, which has not had an active exchange with Korea, will be considered and the efficient method will be proposed. The Czech Republic is geopolitically located in the center of Europe and its infrastructure like industrial construction, investment environment, human resources is outstanding among Visegrad Group. The Czech Republic has a remarkable cultural border-crossing phenomenon, and as a complex country of cultural and religious characteristics of eastern and western European, it is a powerful nation leading Central Europe. Therefore, the animation exchange of Czech and Korea is valuable in culture and economy of both nations. Through such an animation exchange of both nations, not only Korean animation secures the diversity of exchange but also insignificant cultural exchange after formal establishment of diplomatic relations in 1990, will be revitalized and international firm relationship of both nations will be established. Therefore, as an activation plan or cultural exchange of Korea and the Czech Republic, concrete plan like Stop Motion Animation Workshop is proposed.

In this study, we evaluated environmental-friendly disease control methods using essential oils, antagonistic bacteria, or cooking oil and egg yolk mixture (COY). Among the five tested plant essential oils, Eucalyptus approximans oil shown the highest effect to control of the downy mildew disease (60% disease control value). Interestingly enough, well known antagonistic bacteria against various fungal pathogens were appeared lower control efficiency than plant essential oils. In field conditions, the cooking oil and yolk mixture (COY) treatments shown significantly decreased the downy mildew incidence with 0.3% (disease conttrol value 84%) and 0.5% concentration (disease control value 91%). Our findings suggest that the COY has a great potential as the eco-friendly downy mildew disease control formulation.

The purpose of this study was to demonstrate the quality characteristics of Brassica juncea cultivated in Jeongseon (BJJ), South Korea. We analyzed the nutritional components and antioxidant activity of BJJ. As a result of the free sugar analysis, the contents of glucose and fructose in BJJ were $0.29{\pm}0.02g/100g$ and $0.10{\pm}0.00g/100g$, respectively. The major fatty acids were palmitic acid, octadecenoic acid and stearic acid. The palmitic acid was the highest at 31.22% of all fatty acids. The major minerals were identified as Ca, P, K, Mg and Na. The contents of vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, vitamin C and vitamin E in BJJ were $0.02{\pm}0.00mg/100g$, $0.087{\pm}0.01mg/100g$, $0.02{\pm}0.00mg/100g$, $0.56{\pm}0.06mg/100g$ and $0.20{\pm}0.03mg\;{\alpha}-TE/100g$, respectively. As a result of the free amino acid analysis, total amino acid contents in BJJ were $2,801.21{\pm}115.38mg/100g$. L-proline content was the highest ($744.30{\pm}119.06mg/100g$) in BJJ. BJJ extract inhibits reactive oxygen species production in 3T3-L1 adipocytes. Also, BJJ extract exhibits a protective effect on oxidative stress in $H_2O_2$-induced human dermal fibroblast. These results indicate that BJJ comprises various valuable nutrients which can be used as functional food ingredients.
