There are many paintings describing butterfly in a folk story or old story but the word of Nabby is showed up because korea culture is subject to a Chinese character culture area. the word of Nabby is originated from flying features of nabby. It was expressed to an Hoju(胡蝶:swallowtail) or Hwangjub(黃蝶:yellow butterfly) in old book, Nabby or Naboi in Dusiunhae(杜詩諺解) issued in 1481, Naboi in Hunmonjahoe(訓夢字會) issued in 1527 and Nami in Simongunhaemungmyung(時夢諺解物名) issued in Sookjong dynasty(1675$\sim$1720). After that it was called Nabeui or Nabby and Nabby became the standard language but it is still called Nabbo or Nabbe in some provinces. The butterfly have been called as jewelry spread out through the world and people have been attracted by its meaning (love, pleasure, luck, long life and eternity) and its beautiful figure so that they have collected poems and paintings about it to appreciate its beauty or have made craft works and personal ornaments of it. This research is to analyze the shape and color of the using the application method of the nubi, which is used as expression method in this research, is suitable to express the beauty of butterfly's shape and the nerve of its wings and the basic material, which is light and have good drape, was used to easily express the rhythmical movement of butterfly's flapping. And thus, this research is to present that the above expression method is suitable to express the beautiful expression of butterfly's image and have unlimited potential energy for developing designs. Results showed that the soft outline of butterfly's wings can coincide with the linear shape of human body. It was also found that the characteristics of nubi method could be diversified as material expression method and the Haute Couture luxurious work could be developed by applying the mixed nubi method to costumes.

To study the succession of epilithic diatoms on the artificial substrate, we investigated environmental factors and the diatom assemblages biweekly from Mar. 2004 to Feb. 2005 at 2 stations in the lower part of the Han River. A total of 60 taxa, representing 2 orders, 3 suborders, 8 families, 17 genera, 51 species, 7 varieties and 2 forms were identified, and mean number of species were 19 species in spring, 20 in summer, 22 in autumn and 22 in winter. Standing crops of epilithic diatoms varied extensively by months and stations; mean values of those were $3.2{\times}10^4$ cells $cm^{-2}$ in spring, $1.9{\times}10^4$ in summer, $1.7{\times}10^4$ in autumn and $1.8{\times}10^5$ in winter. Chlorophyll a concentrations were also similarly showed as variations of the diatom assemblages. Succession of the diatoms in St. 1 was as follows; Melosira varians, Fragilaria capucina, Cyclotella comta, Nitzschia palea in spring, Fragilaria capucina in summer, Aulacoseira granulata var. angustissima in autumn, Aulacoseira granulata var. angustissima and Melosira varians, Cymbella minuta in winter. In station 2, Aulacoseira granulata and Nitzschia palea dominated in spring as a pioneer in early stage of succession, Fragilaria capucina in summer, and Nitzschia palea in winter. According to Canonical Correspondence Analysis (CCA), there showed similar to that of succession of epilithic diatoms within St. 1 and St. 2, and they were not changed by stations but seasons. Nitzschia palea belonged to saprophilous taxa correlated with nitrogen sources and suspended solids. Meanwhile, Fragilaria capucina and Cymbella minuta included in xenosaprobic taxa show correlation with DO and pH. Eurysaprobic taxa correlated with all environmental factors.

Purpose: To assess the relationship between lifestyle and metabolic syndrome in obese children and adolescents. Methods: We retrospectively reviewed the medical records and laboratory results of 109 subjects (7~15 years of age) who visited our pediatric obesity clinic between January 2004 and December 2007. They completed the parent- and self-report questionnaire developed by the Committee on Nutrition of the Korean Pediatric Society to assess lifestyle. The metabolic syndrome was defined as having 3 or more of the following metabolic risk factors: obesity, hypertension, serum triglycerides ${\geq}$110 mg/dL, HDL-cholesterol ${\leq}$40 mg/dL, fasting glucose ${\geq}$110 mg/dL, and insulin ${\geq}20{\mu}IU/mL$. Results: All subjects had at least 1 risk factor (obesity). Sixty-three percent of subjects had 2 or more risk factors, 32% of subjects had 3 or more risk factors, and 10% had 4 or more metabolic risk factors. Hypertriglyceridemia (36%), hypertension (32%), hyperinsulinemia (24%), and HDL-hypocholesterolemia (20%) were observed. Fasting blood glucose levels were normal in all subjects. Hypertension was significantly associated with an unbalanced diet and hyperinsulinemia was significantly associated with parental obesity (p<0.05). Those who ate after 8 PM were at a risk of hypertension (odds ratio, 2.5; 95% CI, 1.0~6.1). Those who did not have a preference for exercise were at a risk of hyperinsulinemia (odds ratio, 10.4; 95% CI, 2~54.1). Those who watched TV for ${\geq}$3 hours/day were at a risk of metabolic syndrome (odds ratio, 4.8; 95% CI, 1.2∼18.8). Conclusion: Lifestyle, such as eating late, no preference for exercise, and TV watching ${\geq}$3 hours/day, were related to metabolic syndrome in obese children and adolescents.

Purpose : We intended to decrease late CNS reaction after radical radiotherapy for an intracranial germinoma by using combined neoadjuvant chemotherapy and involved-field radiotherapy. The efficacy in terms of its acute toxicity and short-term relapse patterns was analyzed. Materials and Methods : Eighteen patients were treated with combined neoadjuvant chemotherapy and radiotherapy between 1995 and 2001. The chemotherapy regimen used was the Children's Cancer Group (CCG) 9921A (cisplatin, cyclophosphamide, VP-16, vincristine) for 5 patients younger than 16 years, BEP (bleomycin, VP-16, cisplatin) for 12 patients, and EP (VP-16, cisplatin) for 1 patient. The radiotherapy covered the whole craniospinal axis for 5 patients, the whole brain for 1, and the partial brain (involved field) for 12. the primary lesion received tumour doses between 3,960 and 5,400 cGy. Results : The male to female ratio was 16:2 and the median age was 16 years old. The tumors were located in the pineal gland in 12 patients, in the suprasellar region in 1, in the basal ganglia In 1, in the thalamus in 1. Three patients had multiple lesions and ventricular seedings were shown at MRI. In 3 patients, tumor cells were detected in the cerebrospinal fluid and MRI detected a spinal seeding in 2 patients. The response to neoadjuvant chemotherapy was complete remission in 5 patients, partial remission in 12, and no response in 1. However, after radiotherapy, all except 1 patient experienced complete remission. The toxicity during or after chemotherapy greater than or equal to grade III was remarkable; hematologic toxicity was observed in 11 patients, liver toxicity in none, kidney toxicity in none, and gastrointestinal toxicity in one. One patient suffered from bleomycin-induced pneumonitis. Radiotherapy was therefore stopped and the patient eventually died of respiratory failure. The other 17 are alive without any evidence of disease or relapse during an average of 20 months follow-up. Conclusion : A high response rate and disease control was experienced, which was the same as observed other studies and the morbidity from chemotherapy-induced toxicity was similar. With these results, the results from adjuvant chemotherapy and involved-field radiotherapy cannot be concluded to be equal to those from extended-field radiotherapy. The long term follow-up study on later complications are required in order to draw definite conclusions on the optimal management with minimum side effects.

Purpose: To determine the appropriate prostate planning target volume (PTV) margins for 3-dimensitional (3D) conformal radiotherapy (CRT) and intensity-modulated radiation therapy (IMRT) patients treated with an endorectal balloon (ERB) under our institutional treatment condition. Materials and Methods: Patients were treated in the supine position. An ERB was inserted into the rectum with 70 cc air prior to planning a CT scan and then each treatment fraction. Electronic portal images (EPIs) and digital reconstructed radiographs (DRR) of planning CT images were used to evaluate inter-fractional patient's setup and ERB errors. To register both image sets, we developed an in-house program written in visual $C^{++}$. A new method to determine prostate PTV margins with an ERB was developed by using the common method. Results: The mean value of patient setup errors was within 1 mm in all directions. The ERB inter-fractional errors in the superior-inferior (SI) and anterior-posterior (AP) directions were larger than in the left-right (LR) direction. The calculated 1D symmetric PTV margins were 3.0 mm, 8.2 mm, and 8.5 mm for 3D CRT and 4.1 mm, 7.9 mm, and 10.3 mm for IMRT in LR, SI, and AP, respectively according to the new method including ERB random errors. Conclusion: The ERB random error contributes to the deformation of the prostate, which affects the original treatment planning. Thus, a new PTV margin method includes dose blurring effects of ERB. The correction of ERB systematic error is a prerequisite since the new method only accounts for ERB random error.

Anabolic steroid compounds are widely used for the increase of muscle mass, density of bone and athletic ability. The present study conducted to evaluate the effects of nandrolone decanoate (ND), one of the anabolic steroid compounds, on disuse muscle atrophy and healing process of bone in dogs. Twenty physically healthy dogs of both sexes were used in this experiment and divided into three groups: group A (control), group B (low dose M-1.5 mg/kg) and group C (high dose ND-7.5 mg/kg). One-mm strip of full thickness bone was excised from the radius below the pronator teres muscle for the artificial fracture and then the fractured ends were fixed in apposition with bone plate leaving 1mm gap, and finally immobilized externally by Robert John's bandage for 4 weeks. ND was administered intramuscularly once a week far 8 weeks. Body weight, muscle mass change and fracture gap of the bone were evaluated immediately after surgery, and 2, 4, and 8 weeks after surgery. The rates of muscle mass change 8 weeks after surgery were $-2.75\pm0.16\%,\;1.68\pm0.11\%\;and\;1.74\pm0.48\%$ in groups A, B and C, respectively. The significant increase (p<0.05) of muscle mass increments were found in the treated groups. The fibrous connective tissue layer in the fracture gaps of the treated groups increased more than the control, especially in the group C at 4th week. More dense fibrous connective tissue were found in the treated groups at 8th week. Collectively, our results suggested that ND was an effective anabolic agent for the immobilized disuse muscle and bone healing.

Background: Mycobacterium tuberculosis is a facultative intracellular pathogen which persists and multiplies within macrophage. Competent cell mediated immunity by cooperation of both T lymphocyte and macrophage of the host is required to kill the Mycobacterium tuberculosis. But a precise understanding of the pathogenesis of tuberculosis infection in pulmonary alveolar macrophage has not been achived. Research on the macrophage's basic microbicidal mechanism has elucidated the importance of oxygen-dependent or oxygen-independent components. Oxygen dependent processing begins with the reduction of oxygen by NADPH oxidase and generation of superoxide. In this study, the oxidative metabolic status of blood monocyte and pulmonary alveolar macrophage in patients with active pulmonary tuberculosis was accessed and compared with that of healthy control subjects to know whether there was a basic difference in superoxide generation by mononuclear cells between two groups. Methods: Pulmonary alveolar macrophage was purified after performing BAL(bronchoalveolar lavage) through the bronchi of infected lesion by plastic adhesion method. Blood monocyte was purified by Ficoll-Hypaque method. Superoxide generation by blood monocyte and pulmonary alveolar macrophage was measured by ferricytochrome-C reduction method after either stimulated with PMA(phorbol myristate acerate) or non-stimulated states. We also measured the effect of pulmonary tuberculosis patient's serum on superoxide generation by monocyte. Results: 1) Generation of superoxide by alveolar macrophage obtained from patients with pulmonary tuberculosis was little higher than those of controls, and PMA enhanced the generation of 2) Generation of superoxide by blood monocyte obtained from patients with pulmonary tuberculosis was little higher than those of control(p>0.05), and PMA more enhanced the generation of superoxide in patientswith pulmonary tuberculosis than those in controls(p<0.02). 3) Patient's serum enhanced the generation of superoxide by blood monocyte obtained from patients with pulmonary tuberculosis and controls, but not in the case of PMA stimulated blood monocyte. Conclusion: The present study suggest that the phenomenon of M.tuberculosis escape the microbicidal action of macrophage was not result of suppressed superoxide generation by blood monocyte and pulmonary alveolar macrophage, rather there might be a factor to stimulate the generation of superoxide by blood monocyte in pulmonary tuberculosis patient serum, but the comparision with effect of control's serum on superoxide generation needs further elucidation.

Background : Airway remodeling of the asthmatic airway, the result of persistent inflammation in the bronchial wall, is associated with irreversible airway obstruction and the severity of asthma. Previous reports had represented that adminitering CpG-oligodeoxynucleotides (CpG-ODN) before sensitization or challenge by allergens inhibits the development of eosinophilic airway inflammation in a murine model of asthma, but the effects of CpG-ODNs on chronic inflammation and airway remodeling had not been characterized. To investigate the influence of CpG-ODNs on chronic inflammation and remodeling of the airway, we performed studies using a murine model of chronic allergen-induced asthma. Methods : Balb/C mice were sensitized to ovalbumin(OVA) and subsequently exposed to nebulized OVA by means of inhalation twice weekly for 7 weeks. CpG-ODNs($30{\mu}g$) was administered intraperitoneally at sensitization. After final inhalation, mice were evaluated for airway hyperresponsiveness, chronic airway inflammation and remodeling. Results : The mice exposed to chronic and recurrent airway challenge with OVA had persistent airway hyperresponsiveness, chronic inflammation and airway remodeling. Mice treated with CpG-ODNs exhibited decreased bronchial hyperresponsiveness, OVA-specific IgE, chronic inflammation and evidence of airway remodeling, including goblet cell hyperplasia and subepithelial fibrosis. Conclusion : CpG-ODNs was thought to prevent chronic inflammation and remodeling changes in a murine model of chronic asthma.

A series of rearing experiments were conducted to determine the growth rates and feed conversion efficiencies of tilapia in accordance with body size or age in nearly total closed system glass aquariums ($270\;\ell$ each in water volume) and concrete tanks ($4000\;\ell$) from April 10 to October 16, 1987. The fish used for the experiments was a Japanese strain of Oreochromis niloticus, and the size of the fish ranged from 7 g to more than 1,000 g in body weight. The starting stocking rates for each experimental lot were 10 to 20 kg in the glass aquarium ($3.7{\%}$ to $7.4{\%}$ of water volume) and 200 kg in the concrete tank ($5{\%}$ of water volume). A single experimental rearing term was 14 days with slight variations on occasions. Water temperature was designed to be kept at $26^{\circ}C$ but slight fluctuations were inevitable. Dissolved oxygen level was designed to be maintained at around $3\;mg/\ell$, but it also showed some variations. The ammonia level in the glass aquarium section once reached up to $18\;mg/\ell$, but generally remained at around $4\;mg/\ell$, and in the concrete tank section it was maintained at around $1\;mg/ell$. The feed was composed of mainly soybean meal with a small amount of fish meal as the protein source, and the crude protein content was about $32{\%}$. Mean daily growth rate was $3.5{\%}$ of body weight with 0.9 in food conversion ratio in the glass aquarium when the mean weight of fish was around 10 g with gradually reduced performances as the fish grew bigger. When the mean weight was 800 g, mean daily growth rate was $0.5{\%}$ with about 1.5 in food coversion for fish in the glass aquarium, and $0.8{\%}$ and 1.6 for fish in the concrete tank, respectively. According to the mean growth rate obtained from this experiment, it was calculated that the fish reared in the concrete tank require 223 days from 50 g to reach 1,000 g which is the ideal size for market in Korea, at the conditions provided as above, and 302 days from 10 g fingerlings to 800 g fish in the glass aquarium conditions of the closed recirculating water system.

Three mushroom mycelia, Ganoderma lucidum, Hericium erinaceum, and Phellinus linteus, were separately diluted with the natural culture media Acanthopanax senticosus. Solid-state fermentation was used to produce three different A. senticosus-fermented mushroom mycelium groups: G. lucidum mycelia, H. erinaceum mycelia, and P. linteus mycelia. The resulting mycelia were analyzed to assess their efficacies as health functional foods. Optimized fermentation conditions were determined by considering the density and growth speed of mycelia in each A. senticosus-fermented mushroom mycelium group. The cultured mushroom mycelia under the optimized conditions were extracted using water and 70% ethanol. Extraction was followed by filtration, concentration and freeze-drying to produce extract powder of A. senticosus-fermented mushroom mycelia: Water extracts (FM-5111, FM-5121, and FM-5131) and 70% ethanol extracts (FM-5112, FM-5122, and FM-5132). Analysis of extract powder of A. senticosus-fermented mushroom mycelia was performed using the maker compounds eleutheroside B and eleutheroside E. Analysis of ${\beta}$-glucan contents was performed by enzymatic procedures.
