This study looks into stress-related factors that have negative effects on performances of professional dancers. Furthermore, we determine how these factors change their living habits. The objective of this study is the improvement of their mental and physical health as well as their performance capabilities by understanding and enhancing possible solutions. In accordance with this objective, the following conclusion was derived from a comprehensive research into stress and living habits of professional dancers. First, there were seven physical, five mental, two environmental, and nine other factors that impede maximization of the potential of professional dancers in practice and during performances. Second, as for the ways that dancers deal with stress-related factors, they had seven ways to tackle excessive weakening of body strength, four ways to maintain their weight, and four ways bearing on casualties, all in terms of the physical factors. As for the mental factors, they had five means to deal with strain/stress before and during a performance, nine ways to solve concentration problems, six ways to overcome lost confidence; and as for tension with personal relations or the organization, they had six and five ways respectively for solving problems. Included in the environmental factors, there were ten methods for fixing problems with organizational administration and nine ways concerning their practice and performance schedules. Of the other factors related to stress, the dancers had three ways of coping with the lack of artistic perspective and four ways for solving problems arising from the lack of expert knowledge. Generally, the solutions to most of the factors were found outside the professional dancer's scope of work, such as taking a sauna, listening to music, and sleeping well. Irrefutably, it will be very helpful for dancers to improve their dynamic movements and conduct successful performances if various programs involving psychological techniques were researched that could be used to rid professional dancers of the many stress factors.

This study was carried out in order to investigate the processing adaptability of Jeung-pyun. We used rice materals that were developed domestically for improving the utilization of rice. Six cultivars(Ilpoombyeo, Hwasungbyeo, Dasanbyeo, Daeribbyeo 1, Hyangmibyeo 1, Hyangmibyeo 2) of rice were used for making Jeung-pyun. In physicochemical properties of rice, Hwasungbyeo had the highest amylose content(20.4%) and Hyangmibyeo 2 had the lowest one(14.9%). Lipid content was 0.23%(Daeribbyeo 1)~0.43%(Ilpoombyeo), protein content was 7.94%(Ilpoombyeo)~8.43%(Dasanbyeo), and ash content was 0.15%(Hyangmibyeo 2)~1.24%(Daeribbyeo 1). In volume and specific volume of the 3 hour fermented Jeung-pyuns, Ilpoombyeo, Hwasungbyeo, Hyangmibyeo 2 were higher, but in the 7 hour fermented Jeung-pyuns, Dasanbyeo, Daeribbyeo 1, Hyangmibyeo 1 were higher. In the sensory evaluation of the test Jeung-pyuns, the overall quality of the 3 hour fermented Jeung-pyuns was not significantly different among the rice cultivars, whereas in the 7 hour fermented Jeung-pyuns Hyangmibyeo 2 had the lowest values. When the 7 hour fermented Jeung-pyuns were stored at 20℃, the hardness and brittleness of Jeung-pyuns were respectively increased, the cohesiveness was respectively decreased. The elasticity was not significantly different among the rice cultivars with storage days, and the gumminess was significantly difference between rice cultivars, respectively increasing during storage, but Hyangmibyeo 2 was the lowest, not increased. In instrumental characteristics of Jeung-pyuns, the hardness was correlated with amylose content and the brittleness and gumminess were highly correlated with the hardness.

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.

Purpose : The purpose of the experiment was to evaluating the diagnostic ability of dental caries detection using digital subtraction in the artificial caries activity model. Materials and Methods : Digital radiographies of five teeth with 8 proximal surfaces were obtained by CCD sensor (Kodak RVG 6100 using a size #2). The digital radiographic images and subtraction images from artificial proximal caries were examined and interpreted. In this study, we proposed novel caries detection method which could diagnose the dental proximal caries from single digital radiographic image. Results : In artificial caries activity model, the range of lesional depth was 572-1,374 μm and the range of lesional area was 36.95-138.52mm². The lesional depth and the area were significantly increased with demineralization time (p<0.001). Furthermore, the proximal caries detection using digital subtraction radiography showed high detection rate compared to the proximal caries examination using simple digital radiograph. Conclusion : The results demonstrated that the digital subtraction radiography from single radiographic image of artificial caries was highly efficient in the detection of dental caries compared to the data from simple digital radiograph.

Purpose : The purpose of this study was to develop the radiographic technique for detecting the demineralization which is known as indication of dental caries. Materials and Methods : This technique was based on the comparing of multiple radiographs which was irradiated by multiple X-ray spectra. For the meaningful comparing, the multiple radiographs were reconstructed to the dosimetrically consistent images using a standard material. The difference of resulting images of same target with multiple spectra represents the difference of response of material as regards the spectra. Results : We have found about 10% of demineralization of dental hard tissues particularly in the proximal region through the analyzing of differences. Conclusion : Most intriguing thing in this investigation was that the method to analyze difference shows us to an anatomic structure of dental hard tissues even if absolute values of optical density were excluded during the procedures.

As the companion animal industry has shown rapid development in Korea, the number of stray animals has increased. This phenomenon has become a social issue in terms of animal welfare, as well as public health-related problems. However, the authoriries have difficulty in coping with the problems, because the number of research studies on stray animals is insufficient. In this study, 49 feces of stray dogs were examined in three animal shelters located in Chung-buk province, in order to establish baseline data for parasite distributions on stray dogs. The zinc-sulfate flotation and formalin-ether sedimentation methods were used for parasite isolation. The examined dogs consisted of 26 males and 23 females, and they were categorized as three groups, including puppies (<1y), juveniles (1~3y), and adults (>3y). On microscopic examination, 28 feces were considered as infected (57.14%). The isolated parasite eggs were composed of 11 different species. The most frequent species was Ancylostoma caninum (28.57%), followed by lsospora canis (24.49%), Trichuris vulpis (10.20%), Toxocara leonina (6.12%), etc. The older dogs had a higher prevalence rate however, no significant relevance were observed between sex and prevalence. All cases of Toxocara leonina infection (n=3) belonged to the male group, and all cases of Trichuris vulpis infection (n=5) belonged to the juvenile group. Infection of A. caninum and 1. canis were identified as the most frequent case of co-infection. A. caninum and 1.canis were the parasites showing the greatest infestation in Chungbuk. In addition, as zoonotic parasites were identified, a proper surveillance system should be required.

Nous nous proposons dans cet article d`e´tablir la typologie du dictionnaire bilingue et d`examiner quelques-uns de ses effets. Le fait que l`usager du dictionnaire bilingue posse`de la compe´tence de la langue maternelle et que la traduction peut se faire en deux directions, en direction de the`me ou de version, nous permet de faire la distinction entre un dictionnaire actif(ou dictionnaire de the`me) et un dictionnaire passif(ou dictionnaire de version). La typologie du dictionnaire bilingue fonctionne donc avec 4 dictionnaires pour toute paire de langues: - deux dictionnaires actifs: A→B (pour A-phones) B→A (pour B-phones) - deux dictionnaires passifs: B→A (pour A-phones) A→B (pour B-phones) Il faut tenir compte dans l`organisation micro-et macrostructurelle de ce principe actif/passif qui sous-tend la typologie du dictionnaire bilingue. Dans cet article nous avons examine´ quelques cas ou` la dichotomie active/passive se manifeste clairement: discrimination de sens pour l`entre´e polyse`me surtout, traitement de l`information grammaticale, information sur les constructions grammaticales et idiosyncrasiques, se´lection et pre´sentation des entre´es lexicales. La difficulte´ du dictionnaire bilingue provenant de ce qu`il pre´tend satisfaire les besoins de deux usagers diffe´rents, usager de la langue source et usager de la langue cible, tout lexicographe doit tenir compte dans ses pratiques lexicographiques de ce Principe actif/passif qui sous-tend la typologie, ce qui lui permettra d`e´liminer les de´tails superficiels et de maximaliser les informations ne´ce´ssaires.
