This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

An increasing frequency of methicillin resistant S. aureus(MRSA), methicillin resistant coagulase negative staphylococci(MRCNS) and Enterococcal infection have been observed in recent years. Teicoplanin is a new glycopeptide antibiotic obstained from the Actinoplanes teicomycetius. The molecular structure and spectrum of antimicrobial activity of teicoplanin is simillar to those of vancomycin, and has been reported to have an excellent in vitro and in vivo effect against various gram-positive infections. Therefore, we evaluated the in vitor susceptibility of gram positive cocci, such as, S. aureus, coagulase negative Staphylococci(CNS), and Enterococci to teicoplanin and vancomycin. The total 253 strains consisted of MSSA(40), MRSA(53), MSCNS(47), MRCNS(48), and Enterococci(65). They were assayed by disc diffusion and agar dilution. During the study, 57% of S. aureus and 49% of CNS showed resistance to methicillin. The inhibitory diameter of teicoplanin was 15-20mm in MSSA, 12-19mm in MRSA, 13-24mm in MSCNS, 11-23mm in MRCNS, and 15-22mm in Enterococci respectively, and showed sensitivity in all but 8 strains(3.2%). The range of the minimum inhibitory concentration (MIC) of teicoplanin to MSSA, MRSA, MSCNS, MRCNS and Enterococci were 9.12-2.0㎍/ml, 0.25-2.0㎍/ml, & 0.25-32㎍/ml, 0.12-1.0㎍/ml respectively. One case of S. haemolyticus was resistant to teicoplanin (32㎍/ml) by the agar dilution method. Eight minor (3.2%) and one major(0.4%) error was observed when the MIC and disk diffusion data were correlated with teicoplanin. As for vancomycin the inhibitory diameter was 17-21mm in MSSA, 15-21mm in MRSA, 18-26mm in MSCNS, 18-25mm in MRCNS, and 16-22mm in Enterococci respectively. The range of the MIC of vancomycin to MSSA, MRSA, MSCNS, MRCNS, and Enterococci were 0.25-1.0㎍/ml, 0.25-4.0㎍/ml, 0.5-2.0㎍/ml and 0.5-2.0㎍/ml respectively. One minor error (0.4%) was seen with the vancomycin disk. The MIC90 of MSSA and MRSA exhibited the same results in teicoplanin (1.0㎍/ml, 1.0㎍/ml), and vancomycin(2.0㎍/ml, 2.0㎍/ml). MSCNS and MRCNS exhibited greater MIC90 with teicoplanin(4.0㎍/ml, 8.0㎍/ml) than vancomycin(2.0㎍/ml, 2.0㎍/ml). Incontrase Enterococci were more susceptible to teicoplanin(0.5㎍/ml) than to vancomucin (2.0㎍/ml). Results from this analysis indicated that both teicoplanin and vancomycin were very excellent for gram positive infections, especially those resistant to methicillin.

In the diagnostic radiology of the localization foreign body, conventional radiography are various technique. Radiographic foreign body localization is a procedure for determining the presence, and later the position, of any extraneous object or material within the body. For localization of foreign bodies, the radiographic method is the most satisfactory. It permits direct observation of the foreign body, as well as providing a permanent record. There are various methods of foreign body localization, each having its own particular merits. I discovered a new radiographic method. The method are as follows. 1. Arrange the tube and fluoroscopic screen as for ordinary horizontal fluoroscopy. Investigate for presence and position of the foreign body. Direct the path of the CR through the foreign body by narrowing or "closing down" the shutter opening, and mark the skin surface to identify the position of the foreign body. 2. Position the X-ray tube, aligning the CR to the spot marked on the skin surface. Select the most practical FFD. Which maybe 30, 36, or 40 inches, but the exact FFD must be known, at the time of exposure, the exact distance should be indicated on the film by suitable lead marks. (+ type) 3. Position the film beneath the part or area and make an exposure using about one-half to two-thirds of the mAs normally reguired for the part in question. 4. Shift the tube a known distance (about 25 percent of the FFD) cephalad, caudad, or transversely and make a second exposure using the same factors. 5. Process the film in the usual manner. 6. Carefully measure the distance between the two images of the foreign body as projected onto the film. 7. Apply the formula : Foreign body - Film distance =image shift × Focal - film distance/image shift - tube shift 8. Applied small focus and fixed FFD. I resulted used in this radiographic technique. 1. Time saving in radiography. 2. The clean image of foreign body on radiographic image. 3. I gained accurate image better than conventional radiography.

The defects evaluation of the interior and the surface would be considered as vital characteristics in predicting the total life span of the steel structure. More importantly, the understandings in the interior composite of welding zone and the notifications in the presence, the formation, and the positioning of the non-metallic inclusion are necessary as well, since there were signs of relatively high defect frequency presented in the welding zone. The ultrasonic testing is a highly recommended technique chosen from among other techniques because of variety of advantages in conducting the non-destructive testing for the welding zone. However, the ultrasonic testing had technical disadvantages referred as followings; the problems due to the couplant between the PZT and the specimen, the formations that were miniature and complex, the moving subject, and the high temperature surrounding the specimen. This research was conducted to resolve the technical disadvantages of the contact ultrasonic testing by studying the non-contact ultrasonic testing where the ultrasonic waves were transferred by the laser, and revealing the specimen defects at its interior part and its surface part. The ultimate goal of this research was to develop a non-destructive evaluation applying the laser manipulated ultrasonic method for the steel structure

연구목적 ' 항경련제인 valproic acid가 초기계태의 신경관 형성에 영향을 주는 기형유발에 대해 입체현미경하에서 관찰하였다 연구재 료 및 방법 : 백색의 Leghorn의 신선한 수정란을 30-35시간 동안 배양하여 Hamburger & Hamilton 기 5-10기의 초기 계태를 천공 필터를 이용하여 분리하여 6-30시간 동안 CO2 세포 배양기에서 배양하였고 무작위로 대조군과 실험군을 분류하였다. 실험군은 valproic acid 의 RPMI culture media 의 농도에 따라 100 ㎍/㎖, 200 ㎍/㎖, 500 ㎍/㎖, 1000 ㎍/㎖ 네가지 군으로 분리하였다. 각각의 대조군과 valproic acid를 처치한 실험군에서 입체 현미경하에서 초기계태의 신경관 형성의 형태학적인 특징과 기형형성의 빈도를 비교하였다. 결과: valproic acid가 없는 RPMI media에서 배양된 대조군은 24개의 계태는 22(91.7%)개는 정상으로 자랐으며 2(8.3%)개는 비정상으로 자랐다 이에 반하여 valproic acid가 처치된 RPMI media에서 배양된 72개의 계태는 42(58.3%)개가 비정상으로 자랐다. 주로 확인된 이상 형태는 신경주름의 변형. 신경관 폐쇄부전, 체절의 장애 및 발육 정지 등 이었다. 계태의 기형 형성은 valproic acid의 농도에 비례하여 증가하였다. valproic acrid 의 농도가 100 ㎍/㎖인 경우 18개 계태 중 2(11.1%)개에서 경미한 신경관 기형이 나타났으며 200 ㎍/㎖인 경우 18개 계태 중 11(61,1%)개는 정상, 7(38.9%)개는 명백한 신경관 기형이 나타났으며 500 ㎍/㎖인 경우 18개의 계태 중 5(27.8%)개는 정상. 13(72.2%)개는 명백한 신경관 기형을 나타냈다. 1000 ㎍/㎖인 경우 18(100%)개 모두 심한 신경관 기형이 나타났다. 결론: valproic acid는 초기계태에서 신경관 기형을 유발 했는데 저농도에서는 일부 경미한 신경관 이상을 보였고 고농도에서는 대부분 심한 신경관 손상을 동반하고 성장 속도가 둔화되어 약 용량의 증가에 따라 기형이 증가되는 dose-dependent manner 로 그 영향이 나타났다. Purpose : The teratogeruc effects of valproic acid widely used as anticonvulsant on the neurulation of the explanted eraly chick embryos were observed by the stereoscope. Materials and Methods: Fresh fertilized white leghorn hen eggs were incubated for 30-35 hours in an e99 incubator. The Hamburger and Hamilton stage 5-10 chick embryos were explanted using the punched-out filter paper explantation technique and cultured in the CO2 cell culture incubator for 6-30 hours. They were randomly divided into a control group and an experimental group. The experimental group was divided into four subgroups according to the valproic acid concentrations of 100 ㎍/㎖, 200 ㎍/㎖, 500 ㎍/㎖, 1000 ㎍/㎖ with which the RPMI culture media were treated. The morphological characteristics and the incidences of teratogenic effects on the neurulation of early chick embryos in the control and experimental groups were compared with each other using the stereomicroscope. Results : Of the 24 chick embryos cultured in the RPMI media without valproic acrid, 22 embryos(91.7%) developed normally, and 2 embryos (8.3%) developed abnormally, in contrast, among 72 embryos cultured in the valproic acrid-treated media, 42 embryos(58.3%) developed abnormally. The frequent anomalous features were deformities of the neural folds, failure of neural tube closure, derangement of somites, and developmental arrest. Of 18 embryos cultured in the media treated each with 100㎍/㎖ of valproic acid, 2 embryos(11.1%) showed mild abnormality of neural tube defect on stereoscopic examination. Of 18 embryos cultured 7l the media treated each with 200㎍/㎖ of valproic acid, 11 embryos(61.1%) developed normally for 20 hours and 7 embryos (38.9%) showed definite neural tube defect. Of 18 embryos cultured in the media 7reated each with 500㎍/㎖ of vaIprolc acid, 5 embryos(27.8%) developed normally (or 20 hours and 13 embryos (72.2% ) showed definite neural tube defect. Of 18 embryos cultured in the media treated each with 1000㎍/㎖ of valproic acid, 1 embryo developed normally for 4 hours but all embryos (100%) showed severe neural tube defect on whole brain after 8 hours of culture. Conclusion : Valproic acid induced mild neural tube defects in low concentration and in high concentration of valproic acid, most chick embryos developed slowly and showed severe neral tube defects. The frequency and severity of abnormal embryos ulcreased in dose-dependent manner.

김유경 한국방송광고공사 2007 광고연구 Vol.0 No.75

본 연구는 브랜드 개성에 대한 일반적 이론과 체계를 응용하여 국가 브랜드 개성의 차원을 규명하고 국가 브랜드개성의 인식에 영향을 미치는 다양한 요인을 살펴보고자 하였다. 이를 위해 세계시장을 대륙별로 나누어 7개국으로부터 1200여명의 표본을 추출하여 9개국에 대한 브랜드 개성의 인식 유형을 도출하였다. 이들 국가 브랜드 개성은 선도성, 활발함, 세련됨, 전통성, 평온함으로 구분하였다. 이들은 다시 목적지에 대한 지각된 특성별로 나누고, 국가브랜드의 기반 구성요소를 토대로 분석하였다. 연구결과 도출된 국가 브랜드개성의 지배적 특성이 명확히 나타났으며 영향요인별 유의성 또한 검증되었다. 이 같은 일련의 발견점과 함의는 국가를 마케팅 및 브랜드 관리의 대상으로 할 경우 시장세분화를 위한 도구로 개성을 활용할 수 있는 방법론을 제시할 뿐만 아니라 향후 자국에 필요한 차별화된 개성을 주요 이미지 차원으로 개발함에 있어 다양한 사고와 접근법을 제공한다. The increased priority placed on branding by marketers in recent years provides an opportunity for researchers to offer valuable insights and guidance. In particular, in highly competitive marketplace, marketers often tend to link their brands to other entities such as people, things and even nations, as a means to improve their brand equity. Understanding this leveraging process, this paper attempted to identify the dimensions of nation brand in terms of its personality, as core attributes of country image. Samples in 7 countries were selected for survey. 5 core dimensions in nation brand personalities were determined in terms of their natures: Leadership, Excitement, Sophistication, Tradition, Peacefulness. Those“ Big Five’were consistently identified in diversely controlled situation by perceived traits of destination such as country of origin, country for tourism, country for investment, country for inhabitation. To measure the five national brand personality dimensions, a reliable, valid and generalizable measurement scale was created. Also, other variables having influences on the formation process of NBP were tested. Theoretical and practical implications regarding the utility of NBP were finally discussed.

Numerous evidences support the pathogenesis that M. pneumonias pneumonia is associated with cell-mediat-ed immune reaction. We report 2 cases of severe M. pneumoniae pneumonia in previously healthy sisters, who were both admitted during an epidemic of M. pneumoniae pneumonia. The elder sister, who was 16 years old, was admitted with M. pneumoniae pneumonia. She showed no response to treatment with clarithroycin and levo-floxacin, and eventually progressed to severe ARDS, requiring mechanical ventilation. After treatment with hydrocortisone (200 mg/day), there were rapid improvements in clinical manifestations and chest radiographic findings. The younger sister, who was 14 years old, was admitted 10 days later, Presenting with fever but no pneumonic lesions on chest radiograph. Just like her sister, the infection showed no response to clarithromycin. Fever persisted and pneumonic consolidation with mild pleural effusion was noticed in the left lower lobe on the 5th hospital-day. After treatment with oral prednisolone (1 mg/kg), she showed rapid defervescence and on the 8th hospital day, no pneumonic lesions were detectable on chest radiograph. Given the fact that the pathogenesis of pneumonia and extrapulmonary manifestations in M. pneumoniae infection is immune-mediated, an immuno-suppressive therapy would be validated for selected patients with M. pneumoniae infections.
