Objective : The purpose of this study is to understand whether group Sensory Integration(SI) therapy has the effect on improvement of motor skill and social function for children with developmental disorder. Method : The subjects were recruited among children received sensory integration therapy at a Children's Development Institute in Dae-Jeon, experimental group is total 5 participating in group sensory integration therapy and control group is also 5 participating in individual sensory integration therapy. The program was constructed for 90 minutes and all children either in the experimental or in the control group went through intervention for 20 weeks. Bruininks-Oseretsky test of Motor Proficiency II, Korean-Scales of Independent Behavior-Revised and Social Maturity Scale were used in order to evaluate the degree of improvement in motor skill and social function. Results : Most children in the experimental group showed improvement in overall aspects of motor skill and the social function comparing pre-intervention with post-intervention, but they did not show any statistically significant differences. However, comparing experimental group with control group, children in the experimental group showed improvement in motor skill and social function. Furthermore, there is statistically significant improvement especially in manual coordination, manual dexterity, and social age and social quotient in Behavior-Revised and Social Maturity Scale. Conclusions : It is found that a group Sensory Integration therapy program has effect on motor skill and social function for children with developmental disorder in this study. In the future study, group SI therapy should be applied for children with diverse diagnosis in order to generalize the effectiveness of therapy.

Background: Corticosteroid is most potent and effective anti-inflammatory medication currently available and inhaled form has been used in the long-tenn control of asthma. Fluticasone propionate(Flixotide/Flovent: FP) is highly potent and topically active inhaled corticosteroid and has at least twice the potency of beclomethasone dipropionate(BDP) in the control of asthma. The aim of this study was to compare the efficacy of FP and BDP in several aspects. Method: Fifty patients with asthma were treated in a randomized, parallel group study of 4 weeks duration. During 2-week run-in period $\beta_2$-agonist was administered. After run-in period, FP $500{\mu}g/day$ was administered via Diskhaler or BDP $800{\mu}g/day$ via reservoir dry-power device. During the run-in and treatment period, morning and evening peak expiratory flow rate(PEFR) were measured daily. Daytime and nighttime asthma symptoms, daytime and night-time rescue bronchodilator use were checked daily. $FEV_{1.0}$ and FVC were measured biweekly in both groups. Results: Three patients treated with FP and seven patient treated with BDP were dropped out. Therefore forty patients completed the study. Morning and evening PEFR was increased and diurnal variation of PEFR decreased significantly in both groups. $FEV_{1.0}$ increased significantly in FP treatment group but not in BDP group. There were also improvements in daytime and night-time asthma symptoms, daytime and night-time rescue bronchodilator use in both groups after treatment There were no significant difference between groups in any of the efficacy parameters. Therapeutic effects were demonstrated earlier in patient treated with FP than BDP. Conclusion: In this study, $500{\mu}g/day$ fluticasone propionate was as effective as $800{\mu}g/day$ beclomethasone dipropionate in the control of asthma. Therapeutic effects were demonstrated earlier in patient treated with FP than BDP without adverse effect.

Purpose: Population based structural and functional maps of the brain provide effective tools for the analysis and interpretation of complex and individually variable brain data. Brain MRI and PET standard templates and statistical probabilistic maps based on image data of Korean normal volunteers have been developed and probabilistic maps based on cytoarchitectonic data have been introduced. A quantification method using these data was developed for the objective assessment of regional intensity in the brain images. Materials and Methods: Age, gender and ethnic specific anatomical and functional brain templates based on MR and PET images of Korean normal volunteers were developed. Korean structural probabilistic maps for 89 brain regions and cytoarchitectonic probabilistic maps for 13 Brodmann areas were transformed onto the standard templates. Brain FDG PET and SPGR MR images of normal volunteers were spatially normalized onto the template of each modality and gender. Regional uptake of radiotracers in PET and gray matter concentration in MR images were then quantified by averaging (or summing) regional intensities weighted using the probabilistic maps of brain regions. Regionally specific effects of aging on glucose metabolism in cingulate cortex were also examined. Results: Quantification program could generate quantification results for single spatially normalized images per 20 seconds. Glucose metabolism change in cingulate gyrus was regionally specific: ratios of glucose metabolism in the rostral anterior cingulate vs. posterior cingulate and the caudal anterior cingulate vs. posterior cingulate were significantly decreased as the age increased. 'Rostral anterior'/'posterior' was decreased by 3.1% per decade of age ($P<10^{-11}$, r=0.81) and 'caudal anterior'/'posterior' was decreased by 1.7% ($P<10^{-8}$, r=0.72). Conclusion: Ethnic specific standard templates and probabilistic maps and quantification program developed in this study will be useful for the analysis of brain image of Korean people since the difference in shape of the hemispheres and the sulcal pattern of brain relative to age, gender, races, and diseases cannot be fully overcome by the nonlinear spatial normalization techniques.

A field study was conducted at Miryang in 2011 to evaluate differential sensitivity of six rice cultivars, three Indica${\times}$Japonica rice (long grain, cv. Hanareumbyeo, Hanareum2, Dasanbyeo) and three Japonica rice (short grain, Nampyung, Ilpumbyeo and Junamjosaeng) cultivars, to benzobicyclon, mesotrione+pretilachlor (MP) and butachlor (control) in transplanting rice and their treatment influences on rice yield. All Indica${\times}$Japonica rice cultivars exhibited susceptible to both benzobicyclon and MP as reflected by higher visual injury and carotenoid biosynthesis inhibition when compared with Japonica rice cutlivars. The percentage of foliar chlorosis of Indica${\times}$Japonica rice was only 0.9~4.7% for benzobicyclon at 13 days after treatment (DAT) and 30.3~64.4% for MP at 5DAT but it increased rapidly to 88.4~91.2% at 12~20DAT. However, most of the Japonica cultivars are tolerant to bezobicyclon and MP. There was no visible leaf chlorosis but carotenoid biosynthesis was slightly inhibited. Based on relative carotenoid content reduction of benzobicyclon and MP to butachlor, the Indica${\times}$Japonica rice showed 4.6~15.6 fold higher compared with the Japonica rice. The heading date of the injured rice plant was delayed by 3 days and panicle number per square meter and ripened grain ratio were reduced as compared with the control treatment of butachlor. Rice yield of the Indica${\times}$Japonica rice cultivars treated with benzobicyclon and MP was reduced by 7~10%, 3~5%. respectively. The result indicates that rice cultivars vary in tolerance to HPPD-Inhibiting herbicides and Indica${\times}$Japonica rices were more susceptible than the Japonica rices to MP and benzobicyclon. Rice yield of the Indica${\times}$Japonica rices was also significantly reduced by the those herbicide treatments.

This study was executed to evaluate the utilization and efficiency of the ceramic biocarrier as the promoter of decomposing on the organic matters for the composting using with pig manure by analyzing of the physico-chemical properties during composting. The treatments of this experiment were consisted of the control(C),microorganism(M), M with natural zeolite(M+Z), M with synthesized zeolite(M+SZ), and M with ceramic biocarrier(M+CZ). The process term of composting was conducted for 30days in the rapidly fermented machine(as pilot system). The results of the physico-chemical properties of the composts were as follows. The changes of temperature during composting was not relative with the microorganism and zeolite materials used in the composts. At all of the treatments were similar to changing of temp. from the initial stage to the final stage. But the added microorganism treatments were higher than control. And the entire pH value of treatments were appeared the same that above temperature result, also the M+CZ and M+SZ treatment among the treatment were higher. At the results of T-C, T-N and C/N ratio, in case of T-C value, the M+CZ treatment was highly more decreased than others. However at the T-N value, there were not the differences from the each treatment. And the C/N ratio was changed according to the changes of T-C and T-N value. Especially, at the M+CZ aud M+SZ treatments were remarkably reduced by about 21.4-23.3 value. In the result of G.I for evaluating of the compost humidity, the M+CZ and M+SZ treatments were close up approximately 110 value compared with the control(G.I value 100). Therefore, the examined ceramic biocarrier amended with compost-promoting-bacteria could be applied to the production of many high quality fertilizers. It is also expected that the results of this researches could be applied to the recycle of the organic wastes based on the experimental results of ceramic biocarrier and compost-promoting-bacteria application.

The inhibitory effects of GS354 and GS389 on cytosolic $Ca^{2+}$ level ($[Ca^{2+}]_{1}$; measured with fura-2 fluorescence) and muscle tension in vascular smooth muscle of rat thoracic aorta were investigated. Both GS354 and GS389 inhibited the contractions induced by high $K^+$ or by norepinephrine. The vasodilator effect of GS354 was accompanied by a decrease in $[Ca^{2+}]_{1}$. The inhibitory effect on high $K^+-stimulated$ $[Ca^{2+}]_{1}$ was antagonized by a $Ca^{2+}$ channel activator, Bay K8644. However, the inhibitory effect on muscle tension was not antagonized by Bay K8644. These results suggest that GS354 inhibits $Ca^{2+}$ channels to decrease $[Ca^{2+}]_{1}$ and also decreases $Ca^{2+}$ sensitivity of contractile elements. The inhibitory effects of GS389 was accompanied by the increase in tissue fluorescence. This increment was not due to fura-2 fluorescence but to endogeneous pyridine nucleotides, suggesting that GS389 has an effect to inhibit mitochondrial function. Because of this interference, effects of GS389 on $[Ca^{2+}]_{1}$ was obscured. However, since sequential addition of Bay K8644 in the presence of GS389 further increased the fluorescence but not muscle tension, this compound seems to have the effects to inhibit $Ca^{2+}$ channels and to decrease $Ca^{2+}$ sensitivity of contractile elements.

Purpose : In Korea, vivax malaria has been reemerged since 1993 after being abscent for more than 10 years. There are several possibilities of casuality of recent epidemic, although it is still unclear. The epidemiologic studies including case analysis and entomological reseach have been undertaken for a successful control measure. But, unfortunately those studies have been rarely dealt with cases of children. Therefore, this study was designed to figure out the characteristics of epidemiolgic and clinical features in children with indigenous vivax malaria. Methods : The study 21 cases below 15 years of age, who were diagnosed as vivax malaria and resided in kyounggi-do province area during 1998. 9~1999. 8. We retrospectively analyzed epidemiologic data concernig with occurrence of vivax, and clinical manifestations, abnormal laboratory findings and outcomes including therapeutic responses. Results : All cases were inhabitants of the endemic areas for vivax malaria in northwestern part of Kyonggi-do or western Kangwon-do, and Paju-gun was the most prevalent. Indigenous malaria cases of this study were more prevalent in children above 10 years old age, and in male. Seasonally, vivax malaria in children occurred throughout the year except January, March and November, and the incidence was the highest in July. Clinical manifestations revealed that 48 hour cyclic fever pattern was the major fever pattern, and other symptoms such as headache, vomiting, poor appetites, chilling, abdominal pain and diarrhea were concomitantly developed. And splenomegaly revealed the main abnormal findings on physical examination, and anemia was the most frequent abnormal finding in laboratory examinations. Young trophozoite was frequently observed on peripheral blood smears. The therapeutic responses of chlorquine were very good in all cases, and no recurrence developed in follow up cases. Conclusion : Geographical and seasonal occurrence distributions of indigenous vivax malaria cases in children were very similar to those of adults as followings; Inhabitants of the endemic region, more prevalent in male, and more common during the summer season. Clinically, 48 hour cyclic fever pattern, splenomegaly and anemia were most frequent and important manifestations in children cases, and clinical courses were not serious. On blood smears, young trophozoite was most dominantly examined in children. Generally, the therapeutic outcomes were excellent, and recurrences were not observed.

This study was performed to investigate the effect of dried powder of chestnut on lipid metabolism, anti-thrombotic effect in rats. Thirty 5-week-old male Sprague Dawley (SD) rats were randomly allocated into five groups and used for experiment. We examined the lipid metabolism and antithrombotic capacity of SD rats administered for 5 weeks with 0.16 g/kg, 0.5 g/kg chestnut flesh powder and 0.16 g/kg, 0.5 g/kg chestnut inner shell and flesh powder mixture, respectively. Food intake, body weight gain and food efficiency ratio were also checked. The levels of serum triglyceride and tree fatty acid were not statistically significant between the all experimental groups. However, the antithrombotic capacity and total lipid levels of the treatment groups were significantly lower than those of the negative control group. These results suggest that the supplementation of chestnut on diet lower the total lipid level in SD rats.

This study was conducted to investigate the dietary effects of locally grown herbs (Mentha piperascens, PM; Rubus coreanus, RC; Tagetes patula, MG) on the growth performance and meat quality of broiler chicken. A total of 600 1-d-old Ross male broiler chicks were divided into eight groups and were fed control diets (antibiotics-medicated or non-medicated commercial diets) or experimental diets (non-medicated diets containing 0.3 or 0.5% PM, 0.3 or 0.5% RC, or 0.3 or 0.5% MG) for 5wk. The body weight gains and feed conversion rates (FCRs) in all the groups that were fed diets containing PM, RC, or MG were significantly improved compared to those in the non-medicated control group (p<0.05). The relative weights of various organs, the serum cholesterol levels, and the GOT/GPT activities in all the groups were also not significantly different. The superoxide dismutase (SOD)-like activities in the groups that were fed diets containing 0.3% PM or 0.3% MG were significantly increased compared to those in the non-medicated control group (p<0.05). The number of cecal lactic-acid bacteria in the groups that were fed diets containing 0.3% PM or 0.5% RC tended to increase. The malondialdehyde contents in the leg muscles were significantly lowered by feeding with PM or MG (p<0.05). The physicochemical properties of the edible meat, including the shear force, water-holding capacity, heat loss, pH, and muscle color degrees $(CIEL^*.\;a^*.\;b^*)$, were not affected by the dietary treatments. It has been suggested that spontaneous Korean plants promote the growth of broilers and may delay lipid oxidation in edible muscles without any negative effect when added in broiler diets.

Purpose : In FSRT (Fractionated stereotactic radiotherapy) planning, we studied the usefulness between multiple arc FSRT and conformal FSRT by comparing tumor shape and DVH (dose volume histogram). Materials and Methods In Chungnam Univ. hospital, we had treated the sixteen patients with FSRT from Aug. 1997 to Dec. 1998. In choosing multiple arc FSRT or conformal FSRT, we had considered If (irregular factor) after calculating tumor volume and surface area. We had considered multiple arc FSRT if tumor shape was similar to sphere or the value of If was less than 1.25, conformal FSRT if tumor shape was very irregular or If was more than 1.3. For evaluation of treatment planning, we had considered the appropriate DVH for tumor volume and for critical organs. Results : The errors between reference point and the coordinates point on AP, Lat radiography were less than 1 mm before treatment. We had planned $3\~$5 arcs for multiple arc FSRT, $5\~6$ports for conformal FSRT. The mean dose distribution of tumor volume of cumulative DVH between multiple arc FSRT and conformal FSRT was 90.6, 85%, respectively. The dose of critical organs irradiated was less than $5\%$ maximum dose of cumulative DVH. Conclusion : We had obtained the similar value between multiple arc FSRT and conformal FSRT, so that we had appropriate treatment planning of FSRT for multiple arc FSRT and conformal FSRT according to tumor shape and size.
