  • Background : The appearance of multiple-drug-resistant Mycobacterium tuberculosis strains has been seriously compromising successful control of tuberculosis. Rifampin-resistance, caused by mutations in the rpoB gene, can be indicative of multiple-drug-resistance, and its detection is of great importance. The present study aimed to develop an oligonucleotide chip for accurate and convenient screening of drug-resistance. Methods : In order to detect point mutations in the rpoB gene, an oligonucleotide chip was prepared by immobilizing specific probe DNA to a microscopic slide glass by a chemical reaction. The probe DNA that was selected from the 81 bp core region of the rpoB gene was designed to have mutation sites at the center. A total of 17 mutant probes related to rifampin-resistance including 8 rifabutin-sensitive mutant probes were used in this study. For accurate determination, wild type probes were prepared for each mutation position with an equal length, which enabled a direct comparison of the hybridization intensities between the mutant and wild type. Results : Mycobacterial genomic DNA from clinical samples was tested with the oligonucleotide chip and the results were compared with those of the drug-susceptibility test in addition to sequencing and INNO-LiPA Rif. TB kit test in some cases. Out of 15 samples, the oligonucleotide chip results of 13 samples showed good agreement with the rifabutin-sensitivity results. The two samples with conflicting result also showed a discrepancy between the other tests, suggesting such possibilities as existence of mixed strains and difference in drug-sensitivity. Further verification of these samples in addition to more case studies are required before the final evaluation of the oligonucleotide chip can be made. Conlcusion : An oligonucleotide chip was developed for the detection of rpoB gene mutations related to drugsusceptibility. The results to date show the potential for using the oligonucleotide chip for accurate and convenient screening of drug-resistance to provide useful information in antituberculosis drug therapy.

  • Background : The incidence of lung adenocarcinoma, which is more prevalent in women and nonsmokers, is increasing. The aim of this study was to determine the prognostic factors of an adenocarcinoma of the lung. Material and method : The clinical information of patients diagnosed with an adenocarcinoma of the lung at the Kosin University Gospel Hospital from January 1994 to July 2004 was reviewed retrospectively. The survival time of these patients was analyzed by the patient's age, gender, performance status, weight loss, smoking history, location of the primary tumor, clinical stage, serologic tumor markers, and treatment modality. Results : For all 422 patients with an adenocarcinoma of the lung, 247 (58.5%) were male, and their mean age was 59.8 years the. The majority of patients were smokers (58.3%), and the tumors were located in the periphery (59.7%). In the smokers, the tumor was located more in the central airway compared to the non-smokers (42.8% vs. 31.9%, p=0.12). The overall median survival time was 390 days (95% CI;304-436 days). Univariate survival analysis revealed that an older age (${\geq}65$ years old), male, weight loss, smoker, central type, advanced clinical stage, elevated serum carcinoembryonic antigen (CEA, >5 ng/ml) and neuron specific enolase (NSE, >15 ng/ml), and the supportive care only were significantly poor prognostic factors. The median survival time was shorter in the smokers than nonsmokers (289 days vs. 533 days, p<0.001). In addition, it was also shorter in the elevated NSE group than in the normal range group (207 days vs. 469 days, p<0.001). Multivariate analysis showed that age, clinical stage, serum NSE, smoking status, and treatment modality were independent predictors of survival (hazard ratios: 1.68, 1.94, 1.92, 2.39 and 1.57, respectively). Conclusions : Smoking is an important prognostic factor in an adenocarcinoma of the lung, but not gender. This suggests that the better prognosis of women is more related with the lower rate of smoking. In addition, the elevated serum NSE is also an important prognostic in an adenocarcinoma of the lung.

Data in this research was obtained by using the questionnaire which was given out to 528 subjects(boys 182, girls 346) in Naju city area. The awareness of dietary behavior of middle school students put the first priority on breakfast from among 3 meals a day, and they selected 'taste' as the most important criterion. The majority and above of subjects responded that they had ever delivered food at least more than 1 or 2 times a week. This research found that middle school students are tends to regard themselves as being rather close to obesity or fatness. Subjects were also aware that they have some problems with a unbalanced eating habbit and irregular timing of having meals, and more than 40% of the subjects responded that they obtain the most of information about food & dietary behavior through television. Significant difference was found in the food involvement with related variables such as sex, grade, the academic background of mother, self-perception of weight, the way of weight control, perception of problems requiring improvement. Dietary behavior related with variables showed significant difference. Variables are grade, perception of meal importance, selecting standard of food, method of weight control, improvement of eating habits. Dietary behavior is found highly relative with food involvement. Dietary behavior is found highly relative with food involvement. In conclusion, suggestions that could bring motivation to improvement is more essential to the nutrition education rather than knowledge oriented education.

  • BACKGROUND: Currently, national biomass inventory are being established for efficient management of the potential energy sources. Among the various types of biomass, agricultural wastes are considered to take the biggest portion of the total annual biomass generated in Korea, implying its importance. However, the currently estimated amount is not reliable because the old reference data are still used to estimate total annual amount of agricultural wastes. METHODS AND RESULTS: Therefore, to provide reliable estimation data, a correct conversion factor obtained by taking into account the current situation is required. For this, the current study was conducted to provide the conversion factors for each representative 8 crop through a field cultivation study. Also conversion factors for 18 crops were calculated using the average amount of each crop produced during 2004 and 2008, subsequently; total amount of agricultural wastes generated in 2009 was estimated using these conversion factors. The total biomass of rice straw and rice husk generated in 2009 were 6.5 and 1.1 million tons, respectively, which consist 75% of the total agricultural based wastes, while the total biomass of pepper shoots and apple pruning twigs were 1.0 and 0.6 million tons, respectively. Despite the high amount of rice-based biomass, their applicability for bio-energy production is low due to conventional utilization of these materials for animal feeds and beds for animal husbandry. In addition to exact estimation of the total biomass, temporal variations in both generated amount and the type of agricultural biomass materials are also important for efficient utilization; fruit pruning twigs (January to March); barley-, been-, and mustard-related waste materials (April to June); rice-related waste (September to October). CONCLUSION(s): Such information provided in this study can be used to establish a master plan for efficient utilization of the agricultural wastes on purpose of bio-energy production.

  • The purpose of this study was to assess the current materials, methods and difficulties according to the year of licence and educational background of Korean dentists in Class II direct composite resin restorations. Total 17 questions were included in the questionnaire. Questions were broadly divided into two parts: first. operator's information. and second. the materials and methods used in Class II posterior composite restoration. The questionnaire was sent to dentists enrolled in Korean Dental Association via e-mail. Total 12,193 e-mails were distributed to dentists. 2,612 e-mails were opened, and 840 mails (32.2%) were received from respondents. The data was statically analyzed by chi-square test using SPSS(v. 12.0.1, SPSS Inc. Chicago, IL, USA). Male dentists among respondents was 79%. 60.3% of the respondents acquired their licences recently (1998-2007), and 77% practiced in private offices. 83.4% have acquired their knowledge through school lectures, conferences and seminars. For the Class II restorations, gold inlays were preferred by 65.7% of respondents, while direct composite resin restorations were used by 12.1 % amalgam users were only 4.4% of respondents. For the restorative technique, 74.4% of respondents didn't use rubber dam as needed. For the matrix. mylar strip (53.4%), metal matrix (33.8%) and Palodent system (6.5%) were used. 99.6% of respondents restored the Class II cavity by incremental layering. Obtaining of the tight interproximal contact was considered as the most difficult procedure (57.2%) followed by field isolation (21 %). Among various bonding systems, 22.6% of respondents preferred SE Bond and 20.2% used Single Bond. Z-250 was used most frequently among a variety of composite resins.

  • Background: Pulmonary atresia (PA) with ventricular septal defect has various morphology of pulmonary arteries and pulmonary blood flow sources, so pulmonary arterial hypoplasia and arborization abnormality make this anomaly difficult to manage surgically. In cases associated with juxtaductal stenosis, we evaluated the change of the pulmonary arterial and juxtaductal stenotic site after shunt operations, and would like to find useful information in surgical planning and methodology of these patients. Material and Method: Among 59 cases diagnosed as PA with ventricular septal defect associated with juxtaductal stenosis, 29 cases who had cardiac catheterization before and after shunt operation were selected from July, 1991 to July, 1996. In 10 cases of right shunt operation(Group I) and 19 cases of left shunt operation (Group II), the diameters of the descending aorta, both pulmonary arteries, and the juxtaductal stenosis site were measured before and after the shunt operation. Result: In both Group I and II, the pre- and postoperative ratio of diameters of the ipsilateral pulmonary artery to the descending aorta was from 0.78${\pm}$0.31 units to 1.01${\pm}$0.26 units and from 0.67${\pm}$0.18 units to 0.84${\pm}$0.27 units respectively, showing a signigicant increase. The contralateral pulmonary artery index was increased from 0.92${\pm}$0.28 units to 1.05${\pm}$0.15 units and from 0.94${\pm}$0.27 units to 1.08${\pm}$0.37 units respectively, but could not be confirmed statistically. In both groups, the change of juxtaductal stenosis showed an aggravating tendency but of no statistical significance from 0.43${\pm}$0.27 units to 0.39${\pm}$0.25 units and from 0.32${\pm}$0.10 units to 0.30${\pm}$0.16 units respectively, and we experienced 2 total obstruction in Group II. Because the increased pulmonary blood flow by shunt operation has a favorable effect to the pulmonary arterial growth, the shunt operation is a recommended treatment in patients with hypoplastic pulmonary arteries. But in PA with ventricular septal defects, the change of juxtaductal stenosis is very important. In conclusion, the growth of ipsilateral (shunt site) pulmonary artery was promoted by shunt operation, but there is a tendency for the juxtaductal stenosis to be aggravated. And we experienced 2 total obstruction in Group II. Conclusion: Thus, in cases operated with shunt method, much careful postoperative follow up study including angiographic evaluation is needed, and after the shunt operation on the side of pulmonary artery associated with juxtaductal stenosis, early precise planning for total correction is recommended.

  • Working dogs, such as rescue dogs, military watch dogs, guide dogs, and search dogs, are selected by in-training examination of desired traits, including concentration, possessiveness, and boldness. In recent years, genetic information has been considered to be an important factor for the outstanding abilities of working dogs. To characterize the molecular features of the canine genes related to phenotypes for working dogs, we investigated the 24 previously reported genes (AR, BDNF, DAT, DBH, DGCR2, DRD4, MAOA, MAOB, SLC6A4, TH, TPH2, IFT88, KCNA3, TBR2, TRKB, ACE, GNB1, MSTN, PLCL1, SLC25A22, WFIKKN2, APOE, GRIN2B, and PIK3CG) that were categorized to personality, olfactory sense, and athletic/learning ability. We analyzed the chromosomal location, gene-gene interactions, Gene Ontology, and expression patterns of these genes using bioinformatic tools. In addition, variable numbers of tandem repeat (VNTR) or microsatellite (MS) polymorphism in the AR, MAOA, MAOB, TH, DAT, DBH, and DRD4 genes were reviewed. Taken together, we suggest that the genetic background of the canine genes associated with various working dog behaviors and skill performance attributes could be used for proper selection of superior working dogs.

  • Many historical research and facet about modern art in Indonesia which formulating background of contemporary Indonesian Art. Indonesian art critic Sanento Yuliman states that Modern art has been rapidly developing in Indonesia since the Indonesian Independence in 1945. Modern Art is a part of the super culture of the Indonesian metropolitan and is closely related to the contact between the Indonesian and Western Cultures. Its birth was part of the nationalism project, when the Indonesian people consists of various ethnics were determined to become a new nation, the Indonesian nation, and they wished for a new culture, and therefore, a new art. The period 1960s, which was the beginning of the creation and development of the painters and the painters associations, was the first stage of the development of modern art in Indonesia. The second stage showed the important role of the higher education institutes for art. These institutes have developed since the 1950s and in the 1970s they were the main education institutes for painters and other artists. The artists awareness of the medium, forms or the organization of shapes were encouraged more intensely and these encouraged the exploring and experimental attitudes. Meanwhile, the information about the world's modern art, particularly Western Art; was widely and rapidly spread. The 1960s and 1970s were marked by the development of various abstractions and abstract art and the great number of explorations in various new media, like the experiment with collage, assemblage, mixed media. The works of the Neo Art Movement-group in the second half of the 1970s and in the 1980s shows environmental art and installations, influenced by the elements of popular art, from the commercial world and mass media, as well as the involvement of art in the social and environmental affairs. The issues about the environment, frequently launched by the intellectuals in the period of economic development starting in the 1970s, echoed among the artists, and they were widened in the social, art and cultural circles. The Indonesian economic development following the important change in the 1970s has caused a change in the life of the middle and upper class society, as has the change in various aspects of a big city, particularly Jakarta. The new genre emerged in 1975 which indicates contemporary art in Indonesia, when a group of young artists organized a movement, which was widely known as the Indonesian New Art Movement. This movement criticized international style, universalism and the long standing debate on an east-west-dichotomy. As far as the actual practice of the arts was concerned the movement criticized the domination of the art of painting and saw this as a sign of stagnation in Indonesian art development. Based on this criticism 'the movement' introduced ready-mades and installations (Jim Supangkat). Takes almost two decades that the New Art Movement activists were establishing Indonesian Installation art genre as contemporary paradigm and influenced the 1980's gene ration like, FX Harsono, Dadang Christanto, Arahmaiani, Tisna Sanjaya, Diyanto, Andarmanik, entering the 1990's decade as "rebellion period" ; reject towards established aesthetic mainstream i.e. painting, sculpture, graphic art which are insufficient to express "new language" and artistic needs especially to mediate social politic and cultural situation. Installation Art which contains open possibilities of creation become a vehicle for aesthetic establishment rejection and social politics stagnant expression in 1990s. Installation art accommodates two major field; first, the rejection of aesthetic establishment has a consequences an artists quest for medium; deconstruction models and cross disciplines into multi and intermedia i.e. performance, music, video etc. Second aspect is artists' social politic intention for changes, both conclude as characteristics of Indonesian Installation Art and establishing the freedom of expression in contemporary Indonesian Art until today.
