Purpose: The purpose of this study was to examine the effects of early passive range of motion (ROM) exercise on ROM of lower extremities and foot edema in hemiplegic patients after stroke. Methods: The data were collected between August 2009 and April 2010 from 11 patients in the experimental group and 13 in the control group. The passive ROM exercise was performed twice a day for 2 weeks. Results: In the experimental group, ROM of lower extremities (flexion of hip, flexion of knee and ankle) increased significantly compared to that of the control group. There was no significant difference in foot edema between the two groups. Conclusion: The results indicated that the early passive ROM exercise can improve the ROM of lower extremities, but not the foot edema in patients after stroke.

Using the precipitation data observed at the Gochang Standard Weather Observatory (GSWO) during the winter seasons from 2014 to 2016, we analyzed the precipitation characteristics of the winter observation environment. For this study, we used four different types of precipitation gauges, i.e., No Shield (NS), Single Alter (SA), Double Fence Intercomparison Reference (DFIR), and Pit Gauge (PG). We analyzed the data from each to find differences in the accumulated precipitation, characteristics of the precipitation type, and the catch efficiency according to the wind speed based on the DFIR. We then classified these into three precipitation types, i.e., rain, mixed precipitation, and snow, according to temperature data from Gochang's Automated Synoptic Observing System (ASOS). We considered the DFIR to be the standard precipitation gauge for our analysis and the cumulative winter precipitation recorded by each other gauge compared to the DFIR data in the following order (from the most to least similar): SA, NS, and PG. As such, we find that the SA gauge is the most accurate when compared to the standard precipitation gauge used (DFIR), and the PG system is inappropriate for winter observations.

In this study, we isolated and identified bacteria from freshwater and soil collected from Osang reservoir, to screen antimicrobial bacteria against various pathogenic bacteria. 38 strains were isolated and assigned to the class Proteobacteria (22 strains), Actinobacteria (7 strains), Bacteroidets (6 strains), and Firmicutes (3 strains) based on 16S rRNA gene sequence analysis. Among them, strain OS17 showed a good growth inhibition against 5 methicillin-resistant Staphylococcus aureus subsp. aureus strains and Bacillus cereus, Bacillus subtilis, Filobasidium neoformans. As a result of the 16S rRNA gene sequence analysis, strain OS17 show the high similarity with Burkholderia ambifaria $AMMD^T$, B. diffusa $AM747629^T$, B. tettitorii $LK023503^T$ 99.8%, 99.7%, 99.6%, respectively. We investigated cell growth and antimicrobial activity according to commercial culture medium, temperature, pH for culture optimization of strain OS17. Optimal conditions for growth and antimicrobial activity in strain OS17 were found to be: YPD medium, $35^{\circ}C$ and pH 6.5. When the strain was cultured in LB, NB, TSB, R2A media at $20^{\circ}C$ and $25^{\circ}C$, the antimicrobial activity did not show. Culture filtrate of strain OS17 showed antimicrobial activity against 5 MRSA strains, Bacillus cereus, Bacillus subtilis, and Filobasidium neoformans with inhibition zones from 2 to 8 mm. Optimal reaction time was 48 h in YPD medium, 100 rpm and 0.3 vvm in 2 L-scale fed-batch fermentation process for antimicrobial activity. Culture optimization of strain OS17 can be improved on antimicrobial activity. Therefore, the antimicrobial activity of Burkholderia sp. OS17 had potential as antibiotics for pathogens including MRSA.

The bark of Ulmus davidiana var. japonica(Ulmaceae) has been described in traditional books to have diuretic and laxative actions, to ameliorate edematous disease, and to be used in insomnia and gastointestinal disorders. Thus this study was carried out to elucidate some of the pharmacological activities of the plant extracts. The results obtained in tills experiment indicated that its methanol extract elicited remarkable inhibition of HCI.ethanol induced gastric lesion, Shay ulceration and gastric secretion. However, it showed no anti-inflammatory action. The acute toxicity of the extract was low, that is, the minimum lethal dose was more than 2000 mg/kg by oral administration in mice. The systematic fractionation of the methanol extract by hexane, ether, ethylacetate and butanol resulted in potent prevention of gastric erosion in butanol and water fractions.

The current work was carried out to investigate the effect of crossbred Korean native chickens (KNC) on performance and meat quality. A total of 720 chicks (1d of age) was used in this work and were divided into groups by crossbreds (A, B, C and D) and sex (male and female). Crossbreds were A) (KNC egg-meat type C strains ${\times}$ KNC meat type S strains) ${\times}$ Ross broiler, B) (KNC egg-meat type C strains ${\times}$ KNC meat type H strains) ${\times}$ KNC meat type S strains, C) (KNC native R strains${\times}$KNC meat type S strains)${\times}$KNC meat type H strains and D(White Semibroiler Chickens). Experimental diets consisted of 3 phases such as starter (0~5 weeks; CP 20.0%, ME 3,050 kcal/kg), earlier (5~8 weeks; CP 18.0%, ME 3,100 kcal/kg) and finisher (8~12 weeks; CP 16.0%, ME 3,150 kcal/kg). They were fed the broiler diets for 12 weeks at the flat house and thirty six chickens were slaughtered at week 5 and 10. There was no significant difference on the fertility of crossbred KNCs, and the hatchability of B crossbred was low compared to other crossbreds. On body weight (BW), D crossbred resulted in a higher BW after 5 weeks (P<0.05). Body weight gain (BWG) and feed intake (FI) of A crossbred were also significant higher compared to the other crossbreds for all periods. On carcass ratio (CR), A crossbred showed higher CR at 5 weeks, there was no significant among crossbreds at 10 weeks. The partial meat ratio(ala, breast, neck, leg) of C crossbred was the lowest among other crossbreds (P<0.05), but the back meat ratio was not difference among treatments at 5 and 10 weeks. pH of meats have no difference among crossbreds at 5 week, and A crossbred was high compared to other crossbreds at 10 week (P<0.05). The moisture content of D crossbred meat and the protein content of B crossbred meat were high compared to other crossbreds at 5 week. Chemical compositions of meats have no difference among crossbreds at 10 week. Lightness and redness have not significance among crossbreds at 5 week, and redness of A crossbred was the highest among all crossbreds (P<0.05). Shear force and cooking loss of A crossbred were high at 5 week, and cooking loss of A crossbred was low compared with other crossbreds at 10 week. These results suggested the basic data that needed to develope the new strains.

This work was carried out to investigate the performance of growing period of two-way crossed of Korean native chickens parental stocks. A total of four hundred eighty female 2-crossbred chicks were used in this study and they were from National Institute of Animal Science. Groups were four crossbreds (4 replications/crossbred, 30 birds/replication) as A) C strain ${\times}$ Y strain, B) C strain ${\times}$ L strain, C) C strain ${\times}$ G strain and D) C strain ${\times}$ W strain. Body weight of A crossbred was the highest at the age of 8 week (P<0.05) and that of D strain was the lowest for growing period (P<0.05). Body weights of A and B crossbreds were higher than those of C and D crossbreds at the 12 and 16 weeks (P<0.05). Weekly body weights of A and B crossbreds were higher than C and D crossbreds (P<0.05), and weekly body weight of B crossbred was higher compared to other crossbreds at 0~20 weeks old. Weekly feed intake of D crossbred was the lowest among all crossbreds at 0~12, 0~16 and 0~20 weeks old (P<0.05). Weekly feed conversion ratio of C crossbred was the highest among crossbreds (P<0.05). These results can give the basic information for growth related data in 2-way crossbreed Korean Native Chickens, which can be used for the parental stocks for the laying-type of Korean native commercial chickens.

Pulmonary aspergillosis usually results from the colonization of the existing lung lesions by chronic pulmonary diseases, such as tuberculosis. Most cases of pulmonary aspergilloma have been treated surgically for many years because it is a potentially life-threatening disease causing massive hemoptysis. Here we reviewed our results from the last 10 years. Material and Method: We reviewed 31 cases surgically treated from Aug. 1992 to Jul. 2002. retrospectively. This investigation is designed to illustrate the peak age incidence, sex ratio, chief complaints, preoperative study, anatomic location of operative site, postoperative pathologic finding and postoperative complications. Result: The peak age Incidence laid in the 3rd and 4th decade of 20 cases (64.5%). The most common complaint was hemoptysis in 27 cases (87.1%). The 31 cases had a history of treatment with anti-tuberculous drugs under impression of pulmonary tuberculosis. The 19 cases (61.3%) showed the so-called “Air-meniscus sign” on the preoperative chest X-ray. In the 31 cases (100%) on the chest computed tomography. as a preoperative diagnostic modality, positivity was shown in 37.9%, 83.3% was shown on the fungus culture of sputum for Aspergillus, serum immunodiffusion test for A. fumigatus, respectively. The anatomical location of aspergilloma was mainly in the upper lobe in 19 cases (61.3%) and the majority of cases were managed by lobectomy. The postoperative pathologic findings showed that 31 cases (100%) were combined with tuberculosis. The postoperative complications include empyema, prolonged air leakage, remained dead space, postoperative bleeding and these numbers of cases is 3 cases (9.7%), 2 cases (6.45%), 2 cases (6.45%), 1 case (3.23%), respectively. one case was died postoperatively due to massive beeding, and asphyxia. Conclusion: Compared with the previous study, there is no significant difference in results. Preoperative chest computed tomography and immunodiffusion test were more commonly available and showed high positivity. Operations often became technically difficult because of pleural space obliteration, indurated hilar structures, and poor expansion of the remaining lung, which were more prominent in the patients with complex aspergillosis. In such cases, medical treatments and interventional procedures like bronchial artery embolization are preferred. However, cavernostomy is also recommanded with few additional morbidity because of its relatively less invassiveness. Early surgical intervention is the recommended management for patients with simple aspergilloma considering the Row surgical mortality and morbidity in recent days.

This study was carried out to investigate the effects of various regions of sorghum-sorghum hybrid (SSH) silage on nutritive values and qualities of SSH silage. SSH "SS405" was harvested at ripen stage and ensiled. Samples of SSH silage used in this study were collected in three regions (outside, middle and inside). The contents of crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), total digestible nutrients (TDN) and in vitro dry matter digestibility (IVDMD) in SSH silage were not influenced by SSH silage manufacture methods and lactic acid bacteria. The contents of CP in inside region of SSH silage were lower than those of outside and middle regions (p<0.05). However, the contents of NDF, ADF and TDN, and IVDMD were not different between the regions of SSH silage. The content of lactic acid in SSH round bale silage was significantly decreased (p<0.05), as compared to SSH square bale silage (SB), gunny bag silage (GB) and trench silage (TS). The contents of acetic acid and butyric acid in SSH silage were not influenced by SSH silage manufacture methods and lactic acid bacteria. The contents of lactic acid in inside region of SSH silage were lower than those of outside and middle regions (p<0.05). In addition, the contents of lactic acid, acetic acid and butyric acid were not different between the regions of SSH silage. Therefore we suggest that nutritive values and quality of SSH silage were not influenced by regions of sampling collected from these silages.

Background: About 3% of all cancer patients suffer from cancer of unknown primary origin. Generally, carcinoma of unknown primary (CUP) carries a grave prognosis, but primary tumor presented to the neck is exception to this. The aims of study are to determine the role of chemotherapy and to find the prognostic factors in unknown primary tumor presented to the neck. Method and Material: Eighty-four patients were diagnosed with unknown primary tumor presented to the neck between January 1996 and June 2002. Among 84 patients, 43 patients (52%) received chemotherapy, radiation or surgery were performed in 20 patients (23%), 21 patients (25%) had no treatment. Results: The response rates to chemotherapy were 87.5% in CUP only localized to the neck and 44.0% in CUP systemically involved (p=0.012). A median follow-up duration was 6.4 years and overall median survival time was 9 months. The median overall survival time of patients treated with chemotherapy were 17 months and that of patients who received surgery or radiation were 20 months (p=0.3548). The important prognostic factors were performance status and the number of involved organ. Conclusion: The prognosis of patients with CUP presented to the neck is more favorable than that of patients with CUP of other localization. The effectiveness of chemotherapy for CUP only localized to the neck was similar to that of surgery or radiation. The important prognostic factors were performance status and the number of involved organ.

This study centered on the quantitative analysis of about 27 trace elements including toxic ones using instrumental neutron activation analysis of fine ambient particulate matter in the third and fourth industrial complex area of Daejeon city, Korea. For analytical quality control, the certified reference material (NIST, the National Institute of Standards and Technology, U.S.A., SRM 2783, air particulate on filter media) was used. The errors relative to SRM values of Sb, Mn, V, Mg, Na, K, Ti, Co, Zn, and Sm fell below 5%, while those of Cr, Fe, Ba, Th, Ce, Al, and Cu were less than 10%. From the results of the quantitative analysis, the concentration of toxic metals such as As, Mn, Se, V, and Zn were $3.26{\pm}2.72$, $9.86{\pm}4.71$, $2.18{\pm}1.25$, $4.91{\pm}2.41$, $158{\pm}78ng/m^3$, respectively. And the results of factor analysis indicated that there are no more than six factors of sources of fine ambient particulate with statistical significance in the study area.
