Coronoid impingement can cause limitation of mouth opening. In many cases, it appears to be related to the coronoid hyperplasia. We present a case of mouth opening limitation caused by coronoid impingement on the posterior surface of the zygomatic bone without coronoid hyperplasia. The bony changes in coronoid and zygoma including surface irregularity and discontinuity of the cortex and sclerotic change of inner medullary space were noted on computed tomography (CT) scans in different level of axial planes. Through another CT scans in open mouth position could demonstrate that those bony changes were caused by the contact of both surfaces against each other. In case coronoid impingement is suspected of the many possible causes, the open mouth CT scans will be needed to reveal the direct impingement of coronoid on zygoma even without coronoid hyperplasia.

In order to enhance capacity of flood control in a design of open channel, it is desirable to design as a straight-course type except the curved channel that is inevitable. The flow in a curved channel is composed of the secondary flow and the hydraulic jump in case of supercritical flow, also cause the energy loss in the curved channel in case of subcritical flow. Therefor, the hydraulical analysis of a velocity distribution and the water level variation can be applied to prevent the overflow in a curved channel during a flood. The objectives of this research is the analysis of the flow characteristics in a curved channel based on the simulated channel.

During the last several decades, although there have been lots of efforts to develope the high-frequency bottom reflection loss model, the frequency dependence of bottom loss was not considered in most cases because the sea bottom was assumed to be generally much smoother and lower gradient than the sea surface. However, if the sea bottom is rougher than acoustic wavelength, the scattered field will be increased and the reflected field will be decreased. In this paper, the high-frequency bottom reflection losses were obtained through the measurement of reflected waves from the artificially-made-flat sandy bottom. The experimental data were compared with the values calculated by the forward loss model of Mourad & Jackson. Conseouently, we suggest the frequency dependence of bottom reflection loss. 기존 해저면 반사손실 모델들은 해저면을 해수면에 비해 거칠기와 경사도가 매우 평탄하거나 완만한 경계면으로 가정하므로 주파수에 따른변화를 고려하지 않거나 미약하다고 가정하였다. 그러나 고주파를 사용하는 소오나 시스템의 경우, 음파의 파장에 비해 해저면이 거칠다면 음파는 산란 영향이 증가하게 되므로 상대적으로 반사손실 또한 증가하게 된다. 따라서 본 논문에서는 임의로 모의된 사질 성분의 해저면에서 수십 ㎑ 이상의 고주파들을 사용하여 주파수별 반사손실을 계산하고, 이를 기존의 해저면 반사손실 모델과 비교하였으며, 해저면 반사손실의 주파수 종속성을 제시하고자 한다.

Background : An important issue in health care today is in trying to center service around the hospitalized patient. There is a "kindness Movement" developing now. Where in the focus of Health Care is being changed from simply treating the basic physical needs of the patient with sophisticated technology. to keeping emotional well being healthy with more humane and attentive treatment. In our attempt to reach the goal of a completely satisfied patient, we undertook a study of the common complaints of patients, and the subsequent nature of the interventions. Method : The study was carried out in two stages, first the patients made known their complaints by filling out questionnaires, then we collected data on the attempts to alleviate the complaints. The questionnaire provided 19 different complaints, which were then analysed for such variables as content, source of complaint, persons treating the complaint, and length of time and method used to solve the complaint. Result : 1. The Chief complaints made by patients(99.1%) were of physical discomfort, such as pain, nausea, vomiting, indigestion, diarrhea and constipation. 2. The complaints were vioced primarily by either a member of the patient's family, or by the patients themselves(78.4%). 3. The complaints were intervened by nurses alone(53.5%), physicians alone(25.5%), or by nurses and physicians together(19.25%). 4. The method by which the complaints were resolved included the utilization of prescriptions(55.7%), turther explanation and education (25.5%) and notification after treatment(13.2%). 5. Most complaints were voiced during the dayshift (42.6%, 7:00~15:00), followed by the evening shift(36.0%, 15:00~22:00) ;and then the nightshift(21.3%, 22:00~07:00). 6. The time required for successful resolution of the patient's problems varied from 10~88.9mi, according to the nature of the complaint. Conclusion : Hopefully by knowing beforehand the nature of both complaint and intervention, we can anticiapte problems and shorten reaction time, in order to provide for a more satisfied patient.

As imported brand markets are growing up rapidly in Korea, some industries are interested in consumer wants for establishing marketing channels. The purpose of this study was to investigate consumer behavior with different retailers. We used a questionnaire survey and collected data from 250 female consumers aged in twenties at Gangnam area. We used only reliable 232 questionnaires for statistical analysis. The results of the empirical study were as follows: The most of people spent 20%∼40% of clothing expenditure on famous brand products. They purchased more famous brand products at department store and duty free shop than other retail shops. Both department store's customers and duty free shop's customers purchased wallet of handbag the most. The most preferred brand was Burberry for apparel, Louis Vuitton for handbag, and Ferragamo for shoes. In shopping attitudes, department store's customers are more enjoying shopping, impulsive shopping, easily boring on staple goods than duty-free shops customers, Department stores customers purchased to suitable clothes for special place and coordination. We hope that database from this study would help retailers and marketers to plan store distribution channels, and to establish target customer for marketing strategies.

Fatigue is one of the most common complaints of cancer patients. In this study, we analyzed the change of fatigue level and general symptoms as time go by, so that, we could explain more on the mechanism and chance of fatigue in relation with treatment, and explore the influencing factors. Method: The subjects of this study were 50 GI cancer patients who have visited the cancer center of A hospital in Suwon. We measured fatigue by using the Revised Piper Fatigue Scale(RPFS) at the time of starting and finishing induction chemotherapy, and starting the 2nd cycle of chemotherapy. Results: 1) The fatigue score was 2.81, 3.73, and 3.82 in a 10 point scale at the time of starting and finishing induction chemotherapy, and starting the 2nd chemotherapy, respectively. This means fatigue persisted until after the treatment. 2) Fifty two percent of participants complained of some kinds of symptoms when starting the treatment, and the proportion increased up to 92% when finishing the treatment. 3) Fatigue scores were significantly high in patients with fatigue-related symptoms than for patients without those symptoms. 4) Fatigue scores showed significant differences according to patients' general characteristics such as age, educational level, economic status, occupation, diagnosis, hematocrit, weight, and amount of sleepy. Conclusion: We have to develop intervention strategies to reduce fatigue in cancer patients in the consideration of influencing factors.

Objet, which showed up with the art of 20C, is now an important element giving a creative idea to fashion designers in modern times. The purpose of the study is to review how the objet technique was paid attention and recreated in the fashion, through the analysis of works, and the formative features of each technique for fashion, in order to identify the connection of arts and fashion, and the position of fashion as art. The techniques using object appeared in the 20th century fashion are as follows: First, papier-colle, which is adding printed materials onto the surface, is such a technique that adds cut-feeling materials to impose a new texture, or arrange again the cloth-cuts to create a different clothing from the existing one, which went to the extension of materials in the fashion, Second, collage of daily materials expresses directly and emotionally through direct presentation of the objets. Especially, collage of patch-work is reproduced into a new fabric depending on the objet used, giving a standing over the form. Third, ready-made which presents the material meaning only of the objet expands the range of objets which could be used in the fashion by introducing the daily materials having a meaning itself as a fashion. Forth, an attempt to approach to the objets of popular image by designed techniques come out in modern fashion as a graffiti look or a typography look, making the clothing itself an objet to transmit a message directly to the masses. Introduction of various objets and development of expression technique brought out the diversification of materials, and enrichment and extension of expression sphere, which resultingly spreaded the freedom of expression and progressed into the art sphere, making a direct motif to solidify its standing as a formative art.

This study was to identify the degree of the stress and the health -promoting behaviors and to determine affecting factors in female elderly based on the health - promoting behaviors. The subjects were 253 of vulnerable female elderly adults aged over 60 in D city. Data were collected from November 1st to December 30th 2007 by questionnaire survey. The instruments used for this study were the HPI(Health Practice Index) developed by Breslow and the PSS(Perceived Stress Scale) developed by Goldberg. Analysis of data was done by use of frequency, percentage, Chi-square test and logistic regression with SPSS program. The results are summarized as the followings: 1) 50.2% of subjects were exposed to medium degree of stressed group. Factors that affected the stress were significantly different according to the type of family living together and medical insurance. 2) 77.0% of subjects were exposed to low level of the health-promoting behavior group. Factors that affected the health - promoting behavior were significantly different according to the type of family living together and medical insurance. 3) Subjects who were living with their spouse or another family member were more highly affected on the health-promoting behavior than alone. Subjects who were benefited from health insurance more highly affected on the health - promoting behavior than those who got medical care. Subjects who were exposed to the low degree of stress more highly affected on the health - promoting behavior than the medium degree of stress. These results suggest that stressful situation is an important variable in the health - promoting behavior. These findings may give useful information for developing health-promoting programs focused on stress in the vulnerable female elderly adults

In this study we investigated nutritional and anthropometric status, food, exercise, smoking and drinking habits in 50 men and 186 women living in Taegu. More than 80% of subjects were college students at their twenties. Average heights were 172.5cm for men and 162.9cm for women. Average weights were 67.0kg and 51.3kg for men and women, respectively. Av-rage BMIs were 22.6 and 19.9 for men and women. More than half of men did exercise either regularly or irregularly, but 64% of women did not exercise at all. Smoking habit was sharply contrasted between men and women as 56.5% vs 0.5%, while drinking habit was not very dif-ferent between them as 59.4% vs 50.8%. Twelve percent of drinkers was heavy habitual ones as five times per week. Food habits of subjects were generally not good. More than 40% of subjects had food habit score with no higher than 21. Analysis of 240hour recall reveals that fat, calcium intakes were higher but vitamins A and C and dietary fiber intakes were lower than Korean RDA and average Korean adult intakes shown in national nutrition survey for 1990. It is concluded that effective education programs for good food habit and exercise are needed as well as for correction of smoking and drinking habits.
