Purpose: This study was performed to investigate the effects of aromatherapy on headache, stress and immune response of students with tension-type headache. Method: This study employed a two-group pre-post test study design. Data was collected from 44 subjects. Twenty-two subjects were assigned to the experimental group and received aromatherapy massage every other day for 3 weeks, but the other 22 subjects were in the control group and did not receive any intervention. Experiment had been conducted from Apr. 9 through Aug. 25, 2001 and intensity of headache, stress response (serum cortisol, life stress) and immune response(T-cell and natural killer cell ratio) were measured in the course of aromatherapy for both experimental group and control group. Data were analyzed by using $X^2$-test, t-test, Paired t-test and repeated measures ANOVA. Result: Headache scores, serum cortisol levels and life stress scores were significantly decreased in the experimental group after treatment compared to the control group. Conclusion: These findings is suggested that the aromatherapy could be an effective nursing intervention in relaxing and relieving the pain caused by tension-type headache for students.

Based on multi-body dynamic software RecurDyn, this paper proposes a modified form of timing silent chain system combing with the existing problem that vibration and chain tension is too large, which is applied for complicated conditions in a V-type engine, such as high speed, variable loads. The analysis of chain drive meshing characteristics is completed. Using the multi-body dynamic soft-ware RecurDyn, the dynamics characteristics of the improved system is studied, including chain tension, transmission error, chain fluctuations, equivalent spring force in different operating conditions. The study results show that chain tension, transmission error, chain fluctuation and equivalent spring force are within the scope of permission, all of them can meet the design requirement. There-fore, the design of this system is reasonable and practicable. The research results will provide a basis for assessing timing silent chain system in a V-type engine and a theoretical reference for designing and optimizing the timing silent chain system.

The purpose of this study was to investigate the clinical application of relaxation training and oriental medical treatment to the SimDamHeoGup(心膽虛怯) type of ChilJungGuQiJung(七情九氣證) patient. In this case, a male patient, 31 years old, who lost his job two months ago, complained of the tension of body and anxiety. We treated the patient with relaxation training and oriental medical treatment such as herbal medicine, acupuncture treatment and aroma therapy. And we diagnosed his state SimDamHeoGup(心膽虛怯) type of ChilJungGuQiJung(七情九氣證), so we prescribed HaChuBoSimTang(夏朮補心場) for patient. In result, the patient’s tension of body and anxiety was improved, so he could recover his confidence slowly. Conclusionally, relaxation training and oriental medical treatment could be effective method to treat the patient of adjustment disorder with the tension of body and anxiety.

This paper presents the concept design procedure of a floating-type combined renewable energy platform based on hydrodynamic analyses and is focused on the fatigue design of taut-type mooring lines of the platform. Two types of combined renewable energy platforms are considered: a combination of wind turbine, wave turbine and photovoltaic energy plant and a combination of wind turbine, current turbine and photovoltaic energy plant. The basic configurations are conceptually determined from the understanding of floating offshore plants, while the main dimensions have been determined based on a hydrostatic calculation. Fully coupled hydrodynamic analyses have been carried out to identify the motion characteristics of the floating body and the tension histories of the mooring lines. The tension history is used for the fatigue life prediction based on the rain-flow cycle counting method. For the fatigue life prediction, tension life curves from API and the Palmgren-Miner rule are employed.

Objectives : The purpose of this study is to evaluate the Korean medical treatment for chronic tension-type headache, especially chuna manual therapy on cervical vertebrae. Methods : One patient was treated with acupuncture, herbal medication and chuna manual therapy on cervical vertebrae. To evaluate the pain of head and neck, visual analog scale(VAS) was measured. Results : After treatment for 1 week, the pain of head and neck was declined from VAS 10 to VAS 3. Conclusions : Korean medical treatment including acupuncture, herbal medication and cervical chuna manual therapy is effective for chronic tension-type headache. But further studies are required to prove the effectiveness of chuna manual therapy on cevical vertebrae.

Objectives The aim of this study was to report a improvement of tension type headache severity after using the Melonis Pedicus. Methods 3 Taeeumin patients, suffering from headache, treated with Melonis Pedicus, herb medicine, and acupuncture. After the treatment, Severity of headache was evaluated by Numerical Rating Scale(NRS). Also we checked the reponse of the Melonis Pedicus, and vital sign. Results & Conclusions After using the Melonis Pedicus, the severity of headache decreased from NRS 8 to NRS 1(case1), from NRS 10 to NRS 7(case 2), and from NRS 8 to NRS 6(case 3). And there was not any adverse effect. In conclusion, this study shows that using Meloni Pedicus can be effective treatment for Taeeumin tension type headache patient.

Objectives The purpose of this study was to improve the comfort of daily life such as reduction of headache and increase of movement of neck by using muscle relaxation approach and joint movement approach for office worker with tension type headache of foward head posture sitting over 5 hours. Methods For this, 9 male and 15 female participated in the foward head posture with tension type headache. Each group consisted of 3 male and 5 female. Groups are divided into groups, such as muscle relaxation therapy, joint movement therapy, muscle relaxation and joint movement therapy. After intervention for each group for a month, we measured neck movement and head disability index and neck disability index 2 week. SPSS 23.0 (IBM Corp., Armonk, NY, USA) was used for data analysis. The one-way repeated analysis of variance (ANOVA), one-way ANOVA, compared t-test was used for statistical analysis. Results Three intervention groups have brought improvements in neck movement and daily life comfort. There is significant difference in the improvement of neck extension and change in neck disability index between 2 and 4 weeks in the joint movement approach compared to muscle relaxation approach, muscle relaxation and joint movement approach. Conclusions Office workers are exposed to tension type headache. However, muscle relaxation approach and joint movement approach can improve neck movement and daily life comfort.

Tension mask assembly is positioned right behind the glass-made front panels of CRT type display devices. The frame-supported thin metal sheet contains numerous slits, through which electron beams are focused to enhance definition. Pretension is imposed on the masks, especially for enlarged flat screens, in order to avoid vibration due to acoustic or mechanical impact. High temperature assembly process subsequent to pretensioning, however, degenerates the creep resistance of common mask materials, and if tensile stress is high enough, tension on the mask may be loosened substantially due to creep deformation. In this study, the assembly is modeled as a combined structure of beams and wire array, and a numerical simulation is attempted for pretensioning followed by high temperature process. According to a model study, small amount of creep strain is likely to be generated, but its adverse influence is not negligible. Some structural modification measures to reduce the creep-induced tension loosening are proposed and evaluated. Also, optimal configuration of frame structure is sought for, which maintains high tension of masks and minimizes the possible creep of frame simultaneously.
