The present study was made to contribute to thed improvement of the quality of jeans wear advertising, and to the establishment of more effective advertising policy by which the jeans wear advertisements can go well with the unique charateristics of jeans wear. The study analyzed the consumer's attitude and dimention of affective responses toward jeans wear advertisements by type of appeal. The research was implemented through the survery with a representative sample of 344 consumers residing in Seoul. Means, Standard Deviation, ANOVA, Duncan Test, Facor Analysis and Regression were imployed to analyze the data gathered. The results of the study are as follows : (1) There are four dimentions of affective responses toward jeans wear advertisements ; upbeat-activation dimention, erotic-activation dimention, calm-emotional dimention, negative emotional demention. (2) According to consumer's sex, there are significant differences in each dimention of their affective responses. Toward sex-appeal advertisements, men show high degree of affective responses in upbeat-activation dimen-sion and calm-emotional dimension. (3) There is a probability that non-sex-appeal advertisement covers wider range of consumer than sex-appeal advertisements. (4) There is no significant different in affective responses towards both sex-appeal and non-sex-appeal advertisement of jeans wear between and among sex·age and involvement level of consumer. (5) Men prefer sex-appeal advertisement to non-sex-appeal advertisement, while there is no significant differences between the attitude of female consumers toward sex-appeal adver-tisement and non-sex-appeal advertisement. (6) In particular, age of 15∼18 and 30∼35 group of female consumer show very positive attitude toward sex-appeal advertisement. Therefore, there is a need to segment female jeans wear market by age groups. (7) According to the age and the involvement level of consumers, there is a significant differences in their attitudes toward advertise-ment. In case of male consumers, group of low level involvement prefer sex-appeal advertise-ment to non-sex-appeal advertisement. While high level involvement group did not show any significant differences between the attitude toward sex-appeal advertisement and the attitude toward non-sex-appeal advertisement. And the age of 15∼24, low level involvement group of female consumers also more positive attitude toward sex-appeal advertisement than toward non-sex-appeal advertisements.

The purpose of this study is to know load for each human body's knee joint to endure load efficiently, when weight lifter pulls suitable bar in the each weight lifting level. To use the difference of load and correlation between men and women, the conclusion of this stduy is to find parameters to conduct maximum limitation of maximum load to search maximum limitation. The moment of each joint in the lower area was to have a much difference between group of the turunk in the first step. It decreased rapidly until decent and greatly pulled in the second step. Neuromusclar moment increased suddenly in the decrease phase. This phenomenon resulted from shock-absorbing function to sbsorb a load from bar.

Background: The primary aim of this study is to statistically analyze and compare the difference in treatment outcomes based on the frequency and duration of acupotomy treatment for lumbar disk herniation. Methods: The evaluation of efficacy and safety involved using visual analog scale (VAS), numeric rating scale (NRS), Roland Morris disability questionnaire (RMDQ), EuroQol 5-dimention (EQ-5D), and similar parameters. This was achieved through the establishment of a comparable cohort using propensity score matching. Group A comprised 46 patients who underwent 4 sessions of acupotomy treatment for 2 weeks, while Group B consisted of 15 patients who received 6 acupotomy sessions for 3 weeks. Results: For Group A, the average amount of change in VAS values at weeks 4 and 6 was significantly decreased. However, the average amount of change in RMDQ values was not significant. Notably, the average amount of change of EQ-5D values at week 6 increased significantly. As for Group B, the average amount of change of NRS values in weeks 2 and 3 was significantly decreased. Conversely, the average amount of change in RMDQ and EQ-5D values was not significant. In comparing the 2 groups at the final follow-up, the average amount of change in all evaluation values was not significant. Further, no significant interaction effect was observed in the changes over time in all evaluation values between the 2 groups. Conclusion: This study establishes that there was no statistically significant difference in pain reduction, functional impairment, and quality of life improvement between 2 group.

In this research, we make the thin wall chamber to the measurement of heat flux of using a Kerosene/LOx liquid rocket engine's thrust chamber. The wall thickness is one millimeter. We measured outside wall temperature of thrust chamber by nine thermocouple. We suppose the system to the one-dimension unsteady state, and so the heat flux and heat transfer coefficient of thurst chamber are calculated using one-dimensional the transient energy equation by outside wall temperature. In this case, O/F ratio is 2.0, experimental variation is chamber pressure and we got the heat transfer coefficient of the proportion relation of 0.88 times for the chamber pressure.

The patient had bruxism and epilepsy tendency. Inadequate or unstable posterior support was identified due to severe anterior attrition and decreased occlusal vertical dimension. Prematurities of posterior occlusal and wear facets increased the function of anterior teeth, resulting in severe wear. Wear facets displayed sharply defined peripheries, which are matched on articulated diagnostic casts. Also the patient showed C III malocclusion tendency, and lost some facial contour with drooping corners on the mouth. In this case, the alteration of OVD (Occlusal Vertical Dimention) may provide a biologically compatible adjunct to the treatment such as dentofacial esthetics, improved visual proportion in facial heightand mechanical solutions to the force-management of the masticatory system. The patient requires extensive restorative treatment to regain appropriate function, esthetics and comfort. According to the report by Farhad Fays, the average vertical distance from the maxillary to the mandibular mucolabial reflection in the region of the central incisors is approximately 34mm. However, the vertical distance of this patient was found to be 32mm, which was necessary to add gauge 20-sheets to apply vertical dimension. A removable occlusal overlay splint, which restores OVD to the estimated optimalposition, is the general first trial. The patient was observed periodically for 6 weeks, while appropriate adjustments were made vertical dimension to function. When patient felt comfortable with the splint, the teeth were prepared, and provisional restorations are placed for 3 months. The provisional restoration was fabricated by a diagnostic wax-up. When the patient felt comfortable with the provisional restoration, the final restoration mimics OVD, function, and esthetics that have been developed in the treatment restorations. Restoration of the extremely worn dentition presents a substantial challenge to thedentists. Therefore, careful evaluation of the etiology, history, and factors associated with occlusal vertical dimension should be preceded prior to the appropriate treatment planning.

Propose: Due to the rapid growth of medical technologies and the increasing population of older people, we investigated clinical status of ocular dimensions and visual acuity for pre and post cataract surgeries of people over age 90. Methods: From March 2007 to February 2009, we investigated eighty-two eyes of forty-eight patients who had undergone cataract surgeries at an ophthalmic clinic (Ansung, Kyungi-do), investigated maximum corrected vision, axial length, anterior chamber depth and accompanied ocular diseases before and after the surgeries based on the collected data. Results: As patients aged, axial length unchanged but anterior chamber depth decreased over all due to the increase of intraocular lens thickness, and men tended to have a higher degree than women. Seventy-one (86.6%) of eighty-two eyes showed improved corrected vision than before surgeries and forty-three (52.4%) eyes could see more than visual acuity of 0.5. Conclusions: Patients with the systemic disease and accompanied ocular disease showed low vision less than 0.5 after cataract surgery compared to same healthy age peoples. But the others improved correction visual acuity more than 0.5, so the cataract surgery was surely necessary for people over 90 years old and also the presence of ocular disease could have a great influence on correction visual acuity.
