This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

The major purpose of this study is to investigate the characteristic of skilled worker deficiency and training policy from a manpower supply point of view. To achieve the purpose of study wrote out research problems as follows: First in which section did deficiency situations of skilled worker bring about before and after 1990 ? And what was the basic cause of them? Second, did an avoidance tendency of skilled occupation that was generated mainly at manufacturing industry bring about by any factors before and after 1990 ? How was the characteristic of it? Third, were what relations between the governmental training policy of skilled worker and the characteristic of skilled worker deficiency? The major conclusions of this study were as follows : 1) The basic cause of deficiency situation of skilled worker came from pool diminution of 15 year old men - 24 year old men. The deficiency of skilled worker was largely generated at a labor intensive industry of low wages and at a smaller business rather than a large enterprise. And in skill levels high-skilled worker lacked so much. These large deficiency of high-skill worker couldn't be solved as just a huge quantity training of a low-skilled worker : the policy that enlarge school such as an industrial high school, a training center etc. 2) An avoidance tendency of skill occupation was mostly generated by a wage disparity, an uncleanness of working environment, an anxiety of the future in their job etc. In the most of them, the wage disparity was the most significant factor. Also an social avoidance tendency of 3D job was one of the main factors. 3) The governmental policy to solve the deficiency situation of skilled worker was the way that enlarge low-skilled worker : increase student of industrial high school and training center. But these policy was the type that followed 1970s's method, moreover was the plan that overlooked 1990s's social·economical variation that a structure of industry and a need of labor supplier was variously changing. Accordingly, the governmental policy couldn't be actualized as the original supply plan until now. In conclusion, to accomplish the object of training policy and to solve the situations of skilled worker deficiency, the training method of skilled worker should be change into qualitative education which can reflect on student's need and today's uniformly quantitative education should be reformed in the future.

Background: The improved technique for cardiopulmonary resuscitation(CPR) has resulted in the survival of many patients who experienced cardiac arrest. However, mortality in resuscitated patients is high, and the survival rate without brain damage is very low. Various neurological examination models, neuro-imaging techniques, electrophysiological procedures, and biochemical tests have been studied with respect to the detection of cerebral damage and outcome, but an early, reliable prediction of individual outcomes is still uncertain. Methods: We studied twenty patients who had been in a coma for more than 24 hours after CPR, Somatosensory evoked potentials(SEP) were measured within the first three days after CPR. Results: Of the twenty patients, seven patients(35%) had a good outcome, and thirteen patients(65%) had a bad outcome. Of the eleven patients with loss of the cortical evoked potential's N2O peak, all had a bad outcome. Conclusion: SEPs are of great benefit in prognostic evaluation after CPR.

To evaluate the arsenic effect of fish endocrine disruption, crucian carp (Carassius auratus) were treated with 0.5 mg/L and 3.0mg/L of As₂O₃ for 14 days and gonadal development was examined by histological analysis. In ovaries from female crucian carps exposed to 3.0mg/L, immature follicles and atretic follicles were appeared while various normal developmental stages of oocytes were shown in control group. Body weight and Gonadosomatic Index (GSI) of treated carp were also decreased compared to control group. However, no other significant histological changes in liver or kidney were shown in this exposure scheme, This means that reproductive organs are more sensitive than other organs and arsenic may exert endocrine disrupting effect through inhibiting the development of reproductive organ in fish.

Background : Tumor necrosis factor-α(TNF-α) has been thought to play a major role in neurological injury during global brain ischemia and subsequent reperfusion following resuscitation in cardiac arrest. So, we hypothesized that the elevation in TNF-α was dependent upon the duration of the global brain ischemia, and related to delayed neuronal damage. Methods : Fourteen rats were divided two groups ; 1 minute-cardiac arrest group(n=7) and 3 minute-cardiac arrest group(n=7). we induced cardiac arrest by chest compression and clamping of tracheal tube for 1 minute and 3 minutes respectively. And then, resuscitation was initiated. To measure the plasma activity of TNF-α, blood samples were drawn before and at the end of cardiac arrest, and 30, 60, 90, and 120 minutes after initiation reperfusion. At 72 hours after resuscitation, the ND(neurologic deficit) score was determined and the histopathologic outcome of hippocampal CA1 neuron was observed by the percent dead hippocampal CA1 neurons. Results : 1. TNF-α level during the early reperfusion period(<2h) was significantly increased in 3 min-cardiac arrest group compared with 1 min-cardiac arrest group(p=0.0001). 2. There was a no significant difference of neurologic deficit score between 1 min-and 3 min-cardiac arrest. 3. Percent dead hippocampal neurons were significantly increased in 3 min-cardiac arrest group compared with 1 min-cardiac arrest group(9.1±1.2% vs 1.2±0.9%, p<0.05). Conclusions : The results suggest that longer duration of global brain ischemia causes a more profound increase in plasma TNF-α level during the early reperfusion period(<2h) and more delayed neuronal damage than lessor duration of global brain ischemia, and that increase in TNF-α level during the early reperfusion period(<2h) is related to delayed neuronal damage.

The purpose of this study was to determine whether there was any correlation between temporomandibular joint dysfunction and structure of the mandibular condyle. Weanling rats had their masseter muscles resected and immunohistochemical findings were observed a light microscope. The results obtained were as follows : 1. The condylar cartilage region was divided into articular, proliferating, cartilage cell and hypertrophic cell layers according to cell morphology. 2. In light microscopic views, the proliferating and cartilage cell layers of the experimental group decreased gradually and at the 8the week significantly. 3. In immunohistochemical staining for type Ⅰ and Ⅱ collagen, a reaction was detected in the lower part of proliferating cell and cartilage cell layers. In the acrtilage cell layers, a stronger cellular reaction was present. Immunohistochemical staining for type Ⅱ collagen reacted more strongly than that of type Ⅰ collagen. 4. In immunohistochemical staining for proteoglycan, the staining of the experimental group resembled the control group and gradually showed a weak reaction. The proliferating and cartilage cell layers reacted more strongly than the hypertrophic cell layer. 5. In immunohistochemical staining for proliferating cell nuclear antigen(PCNA), the strong reaction was detected in the nucleus of the proliferating cell layer both in control and experimental groups. But the thickness of the proliferating layer decreased in experimental group, consequently the reaction of the experimental group was reduced more than that of the control group.

괴사성 치은염(Necrotizing ulcerative gingivitis, NUG), 괴사성 치주염(necrotizing ulcerative periodontitis, NUP),괴사성 구내염(necrotizing stomatits, NS), 그리고 수암(noma, cancrum oris)은 급속도로 파괴적이며 쇠약하게 하는 잠재성이 큰 구강감염으로 질환의 같은 진행과정에 대해 다른 임상단계로 간주되기도 하나 집합적으로 Vincent's infection, infectious oral necrosis 또는 괴사성 치은구내염(Necrotizing gingivostomati-tis, NG)라고 한다. 이러한 necrotizing gingivostomatitis(NG)의 발생률은 0.19~0.5%이며 2~6세에 가장 높은 발병율을 보인다. Necrotizing gingivostomati-tis는 치명적인 바이러스 감염과 면역체계가 약화된 경우 발생할 수 있으며 주 진단학적 증상으로 동통, 치간유두 부위의 궤양이나 괴사, 치은출혈이 있으며 이차적인 증상은 위막 등이 있다. 이에 본원 소아과에서 의뢰되어 necrotizing gingivostomatitis로 진단받은 환아의 구강내 소견 및 치료경과에 대해 보고하고자 한다. Necrotizing ulcerative gingivitis(NUG), necrotizing ulcerative periodontitis(NUP), necrotizing stomatitis(NS), and Noma(cnacrum oris) are rapidly destructive, debilitating, and potentially serious oral infection which considered to be different clinical stages of the same process. These have been collectively referred to as: Vincent's infection, infectious oral necrosis, or necrotizing gingivostomatitis(NG). Prevalence of necrotizing gingivostomatitis is 0.19~0.5% and peak incidence is 2-6 years of age. The etiology and pathogenesis of necrotizing gingivostomatitis have been associated with virulent bacteria and impaired host defense and the primary diagnostic signs are pain. interdental ulceration or necrosis. and gingival bleeding. Secondary diagnostic sign is pseudomembrane. This case report was about oral conditions and treatment of the patient who referred from the Dept. of PED and diagnosed a necorotizing gingivostomatitis.
