Present study analyzes the rooftop gardening status, floristic composition and cost and return of the rooftop garden in Sylhet City Corporation of northeastern Bangladesh. Data was collected from 450 rooftop gardeners randomly during July-September 2010. Study reveal that rooftop gardening is generally for mental satisfaction (95.3%) followed by leisure time activity (87.8%) in the study area and almost all the family members of gardeners' were involved; while collection of planting materials, sites preparation and marketing of products were reported to be carried out by males only (male 71.33%). Middle income classes were most interested in rooftop gardening (43.78%). The survey recorded 53 plant species (35 families) of which Cucurbitaceae family represented highest eight species. Shrubs (28%) were highest followed by herbs (26%) among agri-crops (36%) and flower species (30%). About 89% of the rooftop gardeners procured planting materials from nursery, market, fair, neighbor, relative and friends and they mostly prefer to use seedlings (48%) for roof gardening followed by direct seed sowing (21%). Gardeners sell products sporadically in different local markets, directly or through intermediaries, with no uniform pricing for system. Rooftop gardening improves the food security and meet nutritional deficiency to the gardeners. Survey revealed that generally very few people consider rooftop gardening commercially to get profit and from the cost-return analysis this gardening system can be economically viable if proper and scientifically managed. The study conclude that active government and NGOs could play vital role to increasing this activities by providing training and motivate people with technical aspects of rooftop gardening.

This is a report on four cases of the lobar emphysema due to proximal bronchial obstruction in the Department of Thoracic Surgery, Hanyang University Hospital, during the period of three and half years from 1972 to 1975. First case, a two years old male child was referred to our Department with the lobar emphysema of the lower lobe of the right lung with pneumonia. This emphysema was developed after aspiration of a piece of peanut. Bronchoscopy revealed that the bronchus of the right lower lobe was obstructed with the foreign body, however removal of the peanut through bronchoscope was not attempted because of corruption and softening of the peanut. The removal of the peanut by bronchotomy was performed after subsiding of acute phase of pulmonary infection. Postoperative course was uneventful and the emphysema was disappeared. Second case, a twenty months old female baby was referred to our Department with lobar emphysema of the lower lobe of the left lung. The emphysema was suddenly developed with coughing and dyspneic symptoms and the diagnosis was made roentgenologically. She gave a history of reccurrent infections of the respiratory tract after birth. Bronchoscopy showed an obstruction of the left main bronchus with the growing of fibrinous tissue on the bronchial mucosa. The protruded tissue in the left main bronchus taken out about O.8ml with biopsy forceps for histological examination. After this procedure, the emphysema of the left lung was disappeared. Histological finding was reported to be a chronic inflammatory granulation tissue. Third case, a two and half years old male child was referred to our Department with roentgenological lobar emphysema. Two weeks prior to admission he had an episode of sudden onset of coughing attack with dyspnea. Bronchoscopy revealed that the bronchus of the left lower lobe was obstructed with a mass which was strongly suspected of a neoplastic tissue. At operation, there was found a perforation of enlarged tuberculous lymph node in the bronchus of the left lower lobe and protrusion of granulation tissue into the bronchus. Ruptured orifice on themembranous wall of the left lower lobe bronchus was closed with interrupted suture after the" removal of a perforated tuberculous lymph node. Postoperative course was uneventful and antituberculous chemotherapy was given. Fourth case, a 47 years old man was admitted to our Department with the complaint of severe dyspnea of few months duration. Twenty years ago, he had a history of lung tuberculosis and was treated for many years. X-ray examination including tomography and bronchography revealed that the upper lobe of the right lung was destroyed with cavities, the lower lobe was completely shrunk, and the right middle lobe was strongly overdistended with narrowing bronchial trees. Differential bronchospirometry and lung scanning confirmed that the respiratory function of the affected lung was impaired almost totally. The value of the right lung was calculated on 6% of oxygen uptake, 1% of Minute volume, and 32% of vital capacity. The right pneumonectomy was performed under the careful consideration of anesthetic and surgical procedures. Postoperative course was uneventful and the respiratory function was improved nearly to the normal level.evel.

Forages, both grazed and conserved, provide the basis of ruminant production systems throughout the world. More than 90 per cent of the feed energy consumed by herbivorous animals world - wide were provided by forages. With such world - wide dependence on forages, the economic and nutritional necessity of been able to characterize them in a meaningful way is vital. The characterization of forages for productive animals is becoming important for several reasons. Relative to conventional laboratory procedures, Near Infrared Reflectance Spectroscopy (NIRS) offers advantages of simplicity, speed, reduced chemical waste, and more cost-effective prediction of product functionality. NIR spectroscopy represents a radical departure from conventional analytical methods, in that entire sample of forage is characterized in terms of its absorption properties in the near infrared region, rather than separate subsamples being treated with various chemicals to isolate specific components. This forces the analyst to abandon his/her traditional narrow focus on the sample (one analyte at a time) and to take a broader view of the relationship between components within the sample and between the sample and the population from which it comes. forage is usually analysed by NIRS in dry and ground presentation. Initial success of NIRS analysis of coarse forages suggest a need to better understand the potential for analysis of minimally processed samples. Preparation costs and possible compositional alterations could be reduced by samples presented to the instrument in undried and unground conditions. NIRS has gained widespread acceptance for the analysis of forage quality constituents on dry material, however little attention has been given to the use of NIRS for chemical determinations on undried and unground forages. Relatively few works reported the use of NIRS to determine quality parameters on undried materials, most of them on both grass and corn silage. Only two works have been found on the determination of quality parameters on fresh forages. The objectives of this paper were (1) to evaluate the use of NIRS for determination of nitrogen and moisture on undried and unground forage samples and (2) to explore two mathematical treatments and two NIR regions to predict chemical parameters on fresh forage. Four hundred forage samples (n: 400) were analysed in a NIRS 6500 instrument (NIR Systems, PA, USA) in reflectance mode. Two mathematical treatments were applied: 1,4,4,1 and 2,5,5,2. Predictive equations were developed using modified partial least squares (MPLS) with internal cross - validation. Coefficient of determination in calibration (${R^2}_{CAL}$) and standard error in cross-validation (SECV) for moisture were 0.92 (12.4) and 0.92 (12.4) for 1,4,4,1 and 2,5,5,2 respectively, on g $kg^{-1}$ dry weight. For crude protein NIRS calibration statistics yield a (${R^2}_{CAL}$) and (SECV) of 0.85 (19.8) and 0.85 (19.6) for 1,4,4,1 and 2,5,5,2 respectively, on a dry weight. It was concluded that NIRS is a suitable method to predict moisture and nitrogen on fresh forage without samples preparation.

The ability to judge a country's scientific standing is vital for the governments and businesses that must decide scientific priorities and funding. In this paper, we analyze the output and outcomes from research investment over the recent years, to measure the quality of scientific research on national scales and to set it in an international context. There are many ways to evaluate the quality of scientific research, but few have proved satisfactory. To measure the quantity and quality of science in different nations, we analyzed the numbers of published research papers and their citations. The number of citations per paper is a useful measure of the impact of a nation's research output. Essential at a were acquired from SCI database by Thomson Scientific, which indexes more than 8,000 journals, representing most significant materials in science and engineering. The purpose of this paper is to evaluate and compare the output and outcomes among nations in a variety of viewpoints and criteria. One of the implications in response to the result of analysis is that sustainable economic development in highly competitive world markets requires a direct engagement in the generation of knowledge. Even modest improvement in healthcare, clean water, sanitation, food, and transport need capabilities in engineering, technology, and medicine beyond many countries' reach. Nations exporting natural resources such as gold and oil can import technology and expertise, but only until these resources are exhausted. For them, sustainability should imply investment in alternative agricultural and technological capabilities through improvements in their skills base. A strong science base does not necessarily leat to wealth generation. However, strength in science has additional benefits for individual nations, and for the world as a whole.

This study analyzed the practical education in fundamentals of nursing, for the 36 nursing schools including 12 4-year nursing schools and 24 junior college nursing schools. This survey was done from september 5th to october 5th in 1995. The results of this study were as follows : 1. Required credit in fundamentals of nursing. 1) The highest incidence of the total required credit was 7 in 4-year nursing school and 9 in junior college. 2) For the lecture course credit, the large number of 4-year nursing school gave 5 credit lessons and 6 credits provided in junior nursing colleges. 3) For the credit of practical education the major portion of 4-year nursing school gave 2 credits instruction, however junior nursing school provided 3 credits. 2. Laboratory practice in fundamentals of nursing. In laboratory practice, the ratio of instructor and student was 1 : 20 in 83.4% of the 4-year nursing school and in 66.7% of the junior nursing school. 3. Contents and hours of fundamental nursing practice. 1) In the area of health assessment and nursing process, the large number of schools allocated following hours : 6 hours for vital signs, 4 hours for nursing process, 2 hours for recording but practice for physical examination and communication was done in few schools. 2) In the area of functional health pattern, the large number of schools allocated practice hours like followings : 2 hours for I/O, 2 hours for gavage feeding, 2 hours for elimination, 6 hours for catheterization, 6 hours for bed making, 2 hours for positioning, 6 hours for personal hygiene, 2 hours for R.O.M, 4 hours for moving turning lifting, 2 hours for inhalation and suction. But C.P.R and terminally ill patient care were taught in smaller number of schools. 3) In the area of special nursing measures, the major portion of nursing schools allocated hours like followings. It consisted of 6 hours for asepsis, 16-18 hours for medication, 2 hours for heat and cold application, 2 hours for wound care. 4) 22.2% of the nursing schools had total review practice time and 36.1% of the nursing schools had the students clinical practice. Based on above mentioned results, 4-year nursing school had faithful practical education of fundamental nursing than junior nursing school. But for the contents and allocated hours for practice education, junior nursing schools were much more contents and hours than 4 year school.

Classical galactosemia is an autosomal recessive disorder of galactose metabolism, caused by a deficiency of the enzyme galactose-1-phosphate uridyltransferase (GALT). Buildup of galactose-1-phosphate is toxic at high levels and can damage the liver, brain, eyes, and other vital organs. The case presented here was that of an 11-day-old female infant who had elevated galatose levels upon initial neonatal screening test with persistent cholestatic jaundice, coagulopathy, and hepatomegaly. The patient was transferred due to aggravation of clinical symptoms including bleeding and jaundice. She had a delayed galactose free diet because of an inappropriate diagnosis. We quickly provided her with a lactose/galactose-restricted diet as per her final diagnosis. Clinical and laboratory results were improved after a few days of treatment. For confirmatory testing for classical galactosaemia, we simultaneously analyzed for GALT enzyme activity and allele-specific PCR/fragments for seven mutations and two polymorphisms in the GALT gene. We were able to find several GALT-deficient and compound heterozygous mutations of the GALT gene.

Purpose: The aim of this study was to evaluate the clinical characteristics, endoscopic findings and risk factors related to the upper gastrointestinal bleeding (UGIB) seen in full-term infants. Methods: A clinical analysis for 9 cases with UGIB confirmed by endoscopy was carried out retrospectively. Patients were admitted to the Department of Pediatrics, Eulji Hospital, from January to December 2003. Results: UGIB from gastric or duodenal mucosal lesions has been seen in 0.13% in newborns infants. All patients were full-term AGA neonates without asphyxic findings at birth. Hematemesis, melena or recurrent vomiting developed within $4.4{\pm}3.8days$ after birth. Vital sign and laboratory test was normal on admission. Endoscopic findings showed hemorrhagic gastritis in 6 cases and peptic ulcers in 3 cases. All patients were successfully managed by medical treatment for $18.6{\pm}5.0days$. On treatment, clinical symptoms improved within $0.9{\pm}0.3days$. Follow-up endoscopy was not performed because there was no recurrence of symptoms in all patients. Case mothers had no history of gastritis, ulcer or anti-ulcer medications before and during pregnancy. Conclusion: If the healthy full-term infants express UGIB within a few days after birth, it is necessary to take careful history of family, mother and delivery process and to practice endoscopy for mucosal lesions of the patients. A follow-up endoscopy dose not seem to be necessary if the infant is clinically well.

CATCH22 syndrome or DiGeorge syndrome is a medical acronym of cardiac defects, abnormal facial appearances, thymic hypoplasia, cleft palate, and hypocalcemia. Patients with CATCH22 syndrome are susceptible to infection due to an absent or hypoplastic thymus and often have difficulties in maintaining good oral hygiene, which may require dental treatment. We present a case of dental treatment for the uncooperative child with CATCH22 syndrome under general anesthesia. A 4-year-old, 14.8 kg boy with CATCH22 syndrome visited Seoul National University Dental Hospital for dental check up. The patient had multiple caries requiring dental treatment. He experienced the corrective heart surgery due to Tetralogy of Fallot a few years ago. General anesthesia was planned because his heart rate and vital sign had shown unstable during the previous conscious sedation procedure. Dental restorative treatments were successfully performed and no complications were observed during and after the procedure. Safe and effective dental management of the patients with CATCH22 syndrome could be performed with the help of general anesthesia and careful monitoring.

Object : With the recent variable treatment modalities and the development of microsurgical techniques, outcomes of surgical and medical management of aneurysm have shown much progress in the last 10 years. However, the management of posterior circulation aneurysm is still a debatable due to its difficulty in limited surgical approach, complicated anatomical structure and many small perforators to vital structure. The purpose of this study is to compare the results of clinical manifestation and outcome of surgery with respect to anterior and posterior circulation aneurysms. Material and Methods : We evaluated the 33 patients with PCAs(posterior circulation aneurysm) and 359 patients with ACAs(anterior circulation aneurysm) treated between 1994 and 1999, retrospectively. Results : Posterior circulation aneurysms showed higher tendency(5 cases, 14.7%) to have unusual shapes, such as dissecting or fusiform compared with anterior circulation aneurysm(15 cases, 4.2%). There were more multiple aneurysms in posterior circulation aneurysm(8 cases, 26.5%) than anterior circulation aneurysm(59 cases, 16.2%). The number of patients with Hunt-Hess grade III or IV on admission were 91(25.3%) in anterior circulation aneurysms, and 14(42.4%) in posterior circulation aneurysms. There were higher incidences of vasospasm and acute hydrocephalus in patients with posterior circulation aneurysm. In cases of anterior circulation aneurysm, neck clipping was possible in 97%. But, in posterior circulation aneurysm, neck clipping was possible only in 67.7% of each. Two hundred forty four cases(85.0%) of all anterior circulation aneurysms and 22 cases(78.6%) of all posterior circulation aneurysms showed good recovery(GR) or moderate disability(MD). The postoperative mortality rates of anterior and posterior circulation aneurysms were 4.9% and 10.7%, respectively. Conclusion : These results indicate that there exist substantial differences with respect to that there were few difference in the aspect of surgery and management outcome between posterior circulation aneurysms and anterior circulation aneurysms.

Background: A tuberculous destroyed lung is sequelae of pulmonary tuberculosis and causes various respiratory symptoms and pulmonary dysfunction. The patients with a tuberculous destroyed lung account for a significant portion of those with chronic lung disease in Korea. However, few reports can be found in the literature. We investigated the computed tomography (CT) findings in a tuberculous destroyed lung and the correlation with lung function. Methods: A retrospective analysis was carried out for 44 patients who were diagnosed with a tuberculous destroyed lung at the Keimyung University Dongsan Hospital between January 2004 and December 2009. Results: A chest CT scan showed various thoracic sequelae of tuberculosis. In lung parenchymal lesions, there were cicatrization atelectasis in 37 cases (84.1%) and emphysema in 13 cases. Bronchiectasis (n=39, 88.6%) was most commonly found in airway lesions. The mean number of destroyed bronchopulmonary segments was 7.7 (range, 4~14). The most common injured segment was the apicoposterior segment of the left upper lobe (n=36, 81.8%). In the pulmonary function test, obstructive ventilatory defects were observed in 31 cases (70.5%), followed by a mixed (n=7) and restrictive ventilatory defect (n=5). The number of destroyed bronchopulmonary segments showed a significant negative correlation with forced vital capacity (FVC), % predicted (r=-0.379, p=0.001) and forced expiratory volume in one second ($FEV_1$), % predicted (r=-0.349, p=0.020). After adjustment for age and smoking status (pack-years), the number of destroyed segments also showed a significant negative correlation with FVC, % predicted (B=-0.070, p=0.014) and $FEV_1$, % predicted (B=-0.050, p=0.022). Conclusion: Tuberculous destroyed lungs commonly showed obstructive ventilatory defects, possibly due to bronchiectasis and emphysema. There was negative correlation between the extent of destruction and lung function.
