  • Objectives: This is an experimental study that attempts to define the effect that self-aromatherapy massage has on depression and satisfaction with life of depressed college students. Methods: Of the total 41 participants, 21 were designated as the experimental group and 20 as the control group. The participants were subject to massages; lavender, sweet orange, mandarin, rosewood, and bergamot aromas diluted to the concentration of 2% in jojoba oil, the carrier oil, were used on the experimental group, and only jojoba oil was used on the control group. Self-aromatherapy massages were conducted for 10 minutes per session, 3 times a week in alternating days, in a period of 2 weeks, and the depression points and satisfaction with life scale were measured before and after massages. Results: This study revealed that there was a statistically significant decrease of depression points in the experimental group, and that there was no significant difference of life satisfaction in both groups. Conclusions: Thus, it is thought self-aromatherapy massages could be used as a practical method of self-mediation that alleviates depression in depressed college students.

  • Purpose: This study investigated general, psychological, and health-related factors related to subjective health status reported from adolescents in multicultural families. Methods: Data from the seventh Korean Youth Risk Behavior Web-based Survey (2001), collected by the Korean Center for Disease Control, was statistically analyzed using the t-test, analysis of variance (ANOVA), and multiple regression analysis. Results: The average points reported for subjective health status was 3.73(SD=0.87)out of 5 points. A major factor accounting for differences in the subjective health status reported was gender. In addition key differences related to psychological and health-related factors were cognition of stress, satisfaction with sleep amount, and moderate physical exercise. Conclusion: The findings suggest that tailored intervention programs should be provided to prevent adolescent problems in multicultural families. We also recommend the development of a program that can help control the variables identified in this study.

  • This paper describes a three-dimensional reference trajectory generation method for giving commands to an unmanned air vehicle (UAV). The trajectory is a set of consecutive curves with constant acceleration during each interval and passing through via-points at specified times or speeds. The functional inputs are three-dimensional positions and times (or speeds) at via-points, and velocities at both boundaries. Its output is the time series of position values satisfying the piecewise constant acceleration condition. To be specific, the shape of the trajectory, known as the path, is first represented by splines using third degree polynomials. A numeric algorithm is then suggested, which can overcome the demerits of cubic spline method and promptly generate a piecewise constant acceleration trajectory from the given path. To show the effectiveness of the present scheme, trajectory generation cases were treated, and their speed calculation errors were evaluated.

  • This paper presents an effective approach to collision-free motion planning of a robot in the work-space including time-varying obstacles. The free arc is defined as a set composed of the configuration points of the robot satisfying collision-free motion constraint at each sampling time. We represent this free arc with respect to the new coordinate frame centered at the goal configuration and there for the collision-free path satisfying motion constraint is obtained by connecting the configuration points of the free arc at each sampling mined from the sequence of free arcs the optimality is determined by the performance index. Therefore the complicated collision-free motion planning problem of a robot is transformed to a simplified SUB_Optimal Collision Avoidance Problem(SOCAP). We analyze the completeness of the proposed approach and show that it is partly guaranteed using the backward motion. Computational complexity of our approach is analyzed theoretically and practical computation time is compared with that of the other method. Simulation results for two cally and practical computation time is compared with that of the other method. Simulation results for two SCARA robot manipulators are presented to verify the efficacy of the proposed method.

  • The purposes of this study are 1) to modify a self-help program for patients having fibromyalgia, 2) to revise instruments to measure the self-efficacy and impact of fibromyalgia; and 3) to test the effects of the program in terms of self-efficacy, physical activities, and clinical symptoms. The subjects of this study were persons diagnosed as fibromyalgia at a university hospital. For the first two purposes, six patients were selected. Twenty three subjects for the third purpose were selected and assigned to experimental and control group on the base of their residence. Thirteen were assigned to the experimental group, while 10 to the control group. Instruments selected for revision were self-efficacy scale and fibromyalgia impact profile. On the basis of the text developed by Arthritis Foundation, a program for patients with fibromyalgia was tentatively developed. Instruments for measurement of self-efficacy and impact of fibromyalgia were revised to show high reliabilities. Results obtained by utilization of the program were as follows : 1) There were no increase of self-efficacy and physical activities. 2) There were no improvement of the number of tender points and pain. 3) There were improvement of depression, fatigue and sleep impairment. These findings indicate the needs for modification of the program with emphasis of exercise for relaxation of tender points, increases of enactive action and vicarious learning.

  • The neck disc is a disease in which the nucleus of the cervical spine escapes between the cervical vertebrae and the intervertebral disc, pressing on the nerve, The neck disc has a high recurrence. If the neck disc is left untreated, the symptoms will worsen and cause inconvenience to life. Therefore, this study is to carry out a successful approach for non-pharmaceutical treatment of neck disc patients. The paper conducted a survey of 102 people who visited the orthopedics of a general hospital at K area from January 15 to March 28, 2024. Symptoms and changes in practice of neck disc were analyzed by t-test. The results of the research are as follows. Firstly, in the case of incorrect sitting posture, 74.5% of the case group was significantly higher than 33.3% of the control group((X2=3.79, p<.01). Secondly, neckache was significantly higher than the control group's average of 12.73 points, with an average of 39.86 points in the case group(t=3.14, p<.01). Thirdly, leg numbness tended to decrease from 7 days after non-drug application compared to before non-drug application. Therefore, the application of this non-drug management was found to be effective in relieving neck disk. The findings derived will contribute to providing valuable insights into the prevention and treatment of neck disc.

  • Presented in this paper is a method to generate round-endmill toolpaths for sculptured surfaces represented as a triangular mesh model. The proposed method is applicable in toolpath generation for ball-endmills and flat-endmills because the round-endmill is a generalized tool in three-axis NC (numerical control) milling. The method uses a wireframe model as the offset model that represents a cutter location surface. Since wireframe models are relatively simple and fast to calculate, the proposed method can process large models and keep high precision. Intersection points with the wireframe offset model and a tool guide plane are calculated, and intersection curves are constructed by tracing the intersection points. The final step of the method is extracting regular curves from the intersection curves including degenerate and self-intersected segments. The proposed method is implemented and tested, and a practical example is presented.

  • A new load/displacement parameter method is developed for the cases that loads are applied to one or more points, and displacements of a structure are controlled at one or more points sinultaneously. The procedure exploits a generalized Riks method, which utilizes load/displacement parameters as scaling factors in order to analyze the post-buckling phenomena including snap-through or snap-back. A convergence characteristic is improved by employing new relaxation factors in incremental displacement parameter, particularly at the region where exhibits severe numerical instability. The improved performance is illustrated by means of numerical example.

  • This survey intends to understand the opinion and status on preschool students' uniform wearing for the purpose of new style development. The results from this study will serve as an activator of related industry. The merit of uniform wearing in these students was recognized primarily as: (1) students can have pride in the schools they attend; (2) they need not worry about clothes to wear every morning. The disadvantage of uniform wearing derives from: (1) students' personality is hardly expressed by uniforms; (2) difficulty in uniform selection suitable for varying weather conditions. This disadvantage felt by their parents suggests the lack of personality expression and appropriate body temperature control. The most prevalent opinion for preference and future improvement points was the consideration of physical activity in children. This indicates that they prefer uniforms rendering minimal restriction on body movements. Other Improvement points stress the activity, uniform laundering and care, convenience in on and off, insulation, colors, design and durability.

  • Gene therapy is becoming a very promising and feasible medical intervention as the understanding of human diseases extends to their molecular levels. Since the first US Food and Drug Administration (FDA)-approved human gene therapy protocol was approved in 1990, over 300 human clinical trial protocols had been approved worldwide so far. Even though some of the domestic gene therapy clinical trials also proved promising and more are awaiting, it should be emphasized that many safety aspects as well as effectiveness aspects should be considered during the development process. Moreover, there seems to be less restricted guidelines from the National Control Authority (NCA) in initiating human clinical trials. This article is intended to suggest some basis and points to consider in the development and evaluation of gene therapy products including antisense oligonucleotides pharmaceuticals.
