The purpose of this study is to examine the influence of dance sports on children's subjective mood change. For this study, 64 primary students were selected at random and were allocated to the experiment group and the control group by 32 each. For 40 minutes, the experiment group performed dance sports whereas the control group played with table tennis balls and rakets. The pretest and post-test were conducted by using the Profile of Mood States. According to the results of repetition measurement and dispersion analysis, it was found that there was a significant difference in the experiment group and the control group. The dance sports group showed lower values than the other group in tension (P<.015), depression (P<.021), anger (P<.032), and confusion (P<.008). On the other hand, the dance sports group showed a higher value in energy (P<.002) and for fatigue, both groups showed higher values. These results proved that dance sports have positive effects on children's subjective mood change.

This research is to integrally explain consuming behavior process of package tour and perceived risk of tourist throughout researching difference by each level based on consuming behavior step, tourist's perceived risk level and level difference. Study model is decided on the basis of the result of pre-practical study on content obtained from theoretical study throughout literature and practical research and analysis throughout posing a question depending on study model was carried out. Giving a concise explanation of study result, Perceived risk of tourist can be measured per 3 steps and pre-perceived risk could be classified between one before purchase-choice time and before attending tour. And perceived risk of tourist has little dfference according to his behavior step and while his behavior process is going on, perceived risk level is getting down without financial perceived risk. It can made perceived risk level decreased by their struggle to getting information, adjusting risk-tolerance level of tourist, non-existence of real risk factor, high level of pre-preceived risk. second, In the relationship analysis between travel information volume and perceived risk, decrease of perceived risk has an interrelationship between travel information volume and functional and physical perceived risks before purchase choice, financial perceived risks before or during travel. It means that he is decreasing perceived risk level for getting information research as part of effort to decrease perceived risk throughout consumer behavior.

해면 정맥동 혈전증(Cavernous Sinus Thrombosis) 치험례

김경원,김용관,장명진,장현석 大韓顎顔面成形再建外科學會 1995 Maxillofacial Plastic Reconstructive Surgery Vol.17 No.4

Cavernous sinus thrombosis is one of the major complications of abscesses of the maxillofacial region. The initial symptoms of CST are usually pain in the eye and tenderness to pressure. this is associated with high fluctuating fever, chills, rapid pulse, and sweating. Venous obstruction subsequently causes edema of the eyelids, lacrimation, proptosis, chemosis and retinal hemorrhages. Blindness is sometimes an accompaniment of cavernous sinus thrombosis when the infection also involves the orbit. There is also cranial nerve involvement (oculomotor, troclear, abducence) and ophthalmoplegia, diminished or absent corneal reflex, ptosis, and dilation of the pupil occur. The terminal stages bring signs of advanced toxemia and meningitis. Infections of the face can cause a septic thrombosis of the cavernous sinus. Furunculosis and infected hair follicles in the nose are frequent causes. Extractions of maxillary anterior teeth in the presence of acute infection and especially curettage of the sockets under such circumstances can cause this condition. The infection is usually staphylococcal. The inflection may spread directly through the pterygoid plexus of veins and the pterygomaxillary space and then ascend into the sinus or it may spread directly from the pterygopalatine space to the orbit. This is possible because of the absence of valves in the angular, facial, and ophthalmic veins. The treatment is empirical antibiotic therapy followed by specific anbibiotic therapy based on blood or pus culture. The inflection usually involves one side, however, it may easily spread to the opposite side through the circulus sinus. Unless it is treated early, the prognosis is poor even in this doses. Occasionally the antibiotics will not adequately resolve the septic thrombus, and death ensues. the use of anticogulants to prevent venous thrombosis has been recommended, but the efficacy of such therapy has not been substantiated. Surgical access through eye enucleation has been suggested. We report a case which demonstrates cavernous sinus thrombosis by the infection after the functional neck dissection and the intraoral reconstruction with auriculomastoid fascio-cutaneous island flap.

Under the current dance educational system, it is difficult to expect a dance from to emerge which would satisfy the educational needs of the future society in its seeking for creativity. In order to establish the necessary position for a dance education fromat which it aimed at the 2000's, current training courses, dance instructors, associated educational system and facilities have been analyzed, and the following conciusions derived. Dance, with respect to training course, must be an independently taught and marked subject in primary, middle and high schools and, to improve the quality of dance instruction dance instructors must be properly qualified and certified, and through the appontment of teachers in charge of dance to positions as dance choreographers, the entire system surrounding and driving dance must improve. In addition, school dance facilities must be expanded by providing more dance practice and performance rooms and y installing such facilities as T.V and VTR equipment. Only when such conditions are satisfied, future dance education be expected to receive due recognition for its importance within the realm of true higher education.

이사도라 던컨의 무용사상과 그 현대적 의의

임혜자,장경진 韓國舞踊敎育學會 1996 韓國舞踊敎育學會誌 Vol.6 No.-

As the 20th century sets in, beauty of dance was becoming more formalized and excessively specialized. Attempts to get not of dissatisfaction with this tendency brought about the birth of modern dance which tried to express the stream of movements by using all parts of body, fully free from forms techniques, music, shoes and dresses. Thanks to its unique characteristic of making dance part of a human life for children, adults, laymen and professional dancers, modern dance has had immense effects on the field of dance as an education-purposed dance. The root of the so-called modern dance must be found in the history of American modern dance, and the origin of modern dance must be attributed to Isadora Duncan's ideology on dance. To understand Duncan's ideology on dance, this study tried to investigate her true character based on her autobiography entitled "MY LIFE". In addition, this study tried to explore the origin of her dance and its meaning by understanding Duncan herself and her ideology In order to illuminate her marvelous traces and brilliant lessons for today's dance development, this study drew the following conclusion from its findings about her life and ideology. Duncan suggested possibility of dance to develop into an independent art free from music, literature, or fine art by discovering the intrinsic meaning of physical movements. She also expanded the scape of expression abilities of dance by discovering the world of mind. Since Duncan's dance is characterized as expression of human emotions, she should be seen as the pioneer of our today's 'modern dance'. In addition, she was not only the founder of modern dance having systematic techniques but also a great revolutionary who awoke the then dance world by introducing a new choreography. From the perspective of dance history, Duncan's ideology on dance provided the basis to construct the underlying principle of 'modern dance'. Based on this conclusion, this study made the following suggestions, first, under the lifetime education philosophy, dance education should be restructured, escaping from the current technique-based education for fostering professional dancers, to introduce a new concept that dance is part of routine human life, second, since Duncan's spirit of dance based on soul expression through natural movements, not on techniques, casts a great meaning to modern dance education, the mission of modern dancers, choreographers, and educators is to inherit Duncan's spirit by keeping and developing a living dance.

In an aging society, there is an increasing possibility of the duplication of the drugs given to patients because they take many kinds of drugs. Among the prescriptions given to the patients who was treated at multiple ambulatory clinics in St. Mary's hospital for one month of September, 2002, in which drugs that has identical or similar effects are prescribed, we analysed and evaluated them by patients' characteristics, kinds of medication, severity of side effects on a case by case basis. More, we assessed the potential additional costs. As a result of this study, the duplication rate turned out to be 6.69% and it was shown that the proportion of the elderly patients over 60 was high. The gastro-intestinal medications took up a large part and most of the cases showed that the danger caused by double taking of medicine was slight, but there were some examples in which the serious side effects were predicted. Expected additional costs were the average 11.349 won and it ranges from the minimum of 56 won to the maximum of 135,720 won. In conclusion, the management of drug histories of the patients who need the plural treatments is very important and the necessity of the individual and professional guidance of taking medicines for the elderly patients is emerged, too.

In this study, the prepared glasses were heat-treated to precipitate the leucite crystal in order to control the thermal expansion coefficient which is an important property of dental porcelain powder. The effect of addition of Li₂O and Na₂O on the amount of the precipitated leucite crystal were also examined. The mixing ratio of the leucite-containing glass must be controlled to match the thermal expansion coefficient of dental porcelain to that of metal. The physical properties of the dental porcelain powder prepared in this study were characterized. The results of this study were obtained as follows : 1. Conditions for the preparation of the maximum amount of leuctie crystal were compostion L-2(2.0 wt% Li₂O added) heat-treated at 950℃. 2. The phase of the precipitated crystals was turned out to be the tetragonal leucite crystal. 3. Maximum relative crystallinity was 64.2% for composition L-2, heat-treated at 950℃. Its linear thermal expansion coefficient was 16.1×10-6/℃ in the range of room temperature to 500℃. 4. The optimum mixing ratio of the leucite-containing glass was 45% in order to match the thermal expansion coefficient of dental porcelain to that of metal. In this case, the thermal expansion coefficient of the prepared dental porcelain was 10.6×10-6/℃ (∼500℃). 5. The physical and chemical properties of the prepared dental porcelain were suitable for the requirements of ISO 6872 and 9693.
