Objectives : This report intended to estimate effects of Jung-an acupuncture on the acquired torticollis caused by muscle contraction. Methods : The patients were treated by Jung-an acupuncture, herb medication and Physical treatment daily. The improvement of the patients was judged by Toronto Western Spasmodic Torticollis Rating Scale(TWSTRS), Tsui's score and Visual Analogue Scale(VAS). Results : After 7 days of treatment, the 2 patients' neck pain and cervical movement were improved. Also, TWSTRS score, Tsui's score and VAS were all reduced. Conclusions : As the Jung-an acupuncture's theological base is organized with meridian theory and myofacial release therapy, We considered the Jung-an acupuncture is effective not only for the skin disease but also for the muscle problem such as torticollis.

The purpose of this study is about the possibility of using bamboo to reinforce concrete in comparison with the reinforced concrete in the same experimental condition by conducting concrete using bamboo material and mechanical test of a bamboo. As a substitute material for the reinforced concrete, to check the possibility of using concrete with bamboo material either saving iron resources or developing lighter material was tried. Conclusions of this study can be summarized as follows; In contrast to reinforced concrete, bamboo concrete was failed brittly about cracked state, the failure was occurred by slip between concrete and bamboo before it reached yielding stress of bamboo. In the pullout test, bamboo pullout specimens were crushed by brittle crack and steel bar pullout specimens by pullout failure.

The analysis on flexural-torsional behavior is fundamental and significant in the analysis and design of structural members. In fact, as most structures are affected by flexure and torsion at the same time, the stress analysis can be performed by superimposing the effects caused by the bending and twisting loads acting seperately as far as the stress-strain relationships maintain linearly elastic. In this paper, cantilever channels for this analysis was considered and the flexural-torsional behaviors of these channel specimens was analytically investigated by superimposing the influence of bending, pure torsion and warping torsion. To conduct an experiment, three cantilever channel specimens were made and tested with strain gauges, Also, these results of theory and experiment were compared with analysis program, SAP2000.

In a box girder, it is an accepted practice in structural engineering to represent the effect of 'shear lag' by adopting an 'effective width' concept. The actual width of flange plate (b) is replaced by a reduced width (b_e) over which the longitudinal stresses may be considered uniformly distributed and the application of the elementary theory of bending to the transformed girder cross section gives the correct value of maximum longitudinal stress (σ_max). This paper provides how to determine the magnitude of 'shear lag' and 'effective width ratio' in case of orthotropic box girder which is simply supported, symmetrically loaded only.

The sufficient safe factor for buckling must be obtained by pertinent stiffness in steel box girder. In this paper, the critical stress of stiffened plate with longitudinal ribs is estimated by the classic approximate method of analysis, integration of the two Karman's differential equtions and the energy method which put strain energy of bending equals the work done during buckling by the compressive force. Especially, according to change of thickness of compressional flange and area of stiffening ribs, the critical load of stiffened plate was analytically investigated and these results of theory and experiment were compared with analysis program, SAP2000

This study was carried out in order to provide the basic information for the development of medicinal plants in Ulleung island, Korea. This area had very rich and diverse flora; 495 taxa with 105 familes, 231 genera, 418 species, 1 subspeies, 63 varieties and 13 forms. The 94 medicinal plants were distributed in Ulleung. They were composed of 10 endemic species, 22 rare species and 62 economic species respectively.

BaFBr:Eu^2+ 형광체를 제조하고, 이 형광체의 열발광 특성과 광자극발광 특성을 조사하였다. 이 형광체의 열발광 g1ow 피이크 온도는 352K와 448K였으며, 주 피이크(352K)에 관여하는 트랩의 활성화에너지는 약 0.96eV이었다. 또한 이 형광체의 광자극발광 스펙트럼의 파장범위는 350~450nm 사이였으며, 광자극발광에 기여하는 트랩의 활성화에너지는 약 0.98eV이었다. 열발광트랩과 광자극발광 트랩의 활성화에너지는 실험오차 내에서 일치하였다. BaFBr:Eu^2+ phosphors were prepared, and the thermoluminescence(TL) and photostimulatedluminescence(PSL) of the prepared phosphors were measured. Two glow peaks around 352 and 448 K are observed for x-ray irradiated BaFBr:Eu^2+ phosphors, and the activation energy of the main glow peak(352 K) was about 0.96 eV. The spectral range of the PSL was 350 ~450 nm, and the activation energy of the trap giving rise to PSL was about 0.98 eV. The activation energy of the traps giving rise to TL is agreed to those giving rise to PSL within experimental error.

Vegetation composition and structure of forest community at Mt. Bislsan, Dalseung-Gun, Daegu in Korea, were studied using a qualitative with a quantitative approach and its vegetation types and various ecological characteristics such as the importance values, species diversity of the major component species analyzed. The forest vegetation were classified into 2 community group, 14 community, 6 group, and total of 18 vegetation units.

고상반응법으로 SrCl_2:Eu^2+ 형광체를 제작하고, 제작한 형광체의 광자극발광과 광발광 특성을 조사하였다. SrCl_2:Eu^2+ 형광체와 광발광 및 광자극발광은 Eu^2+ 의 5d->4f 천이에 기인되었으며, 355 nm의 광으로 여기시켰을 때 광자극발광과 광발광 스펙트럼의 파장범위는 모두 380~440nm이었고, 피이크 파장은 407nm이었다. SrCl_2:Eu^2+형광체의 선량의존성은 2.5 mGy~200mGy영역에서 우수한 선형성을 나타내었으며, 상온에서 광자극발광의 fading은 20분에 60%이었다. SrCl_2:Eu^2+ phosphors were prepared by the solid phase reaction method, and their photostimulated luminescence(PSL) and photoluminescence(PL) characteristics were investigated. The PSL and PL peak of the SrCl_2:Eu^2+ phosphors are due to the 5d->4f transition of Eu^2+ ions in phosphors. The PSL and PL spectrum obtained by the 355 nm exitation was observed in 380~440 nm region with the peak at 407 nm. The dose response of the PSL phosphors were linear within 2.5 mGy ~ 200 mGy of 100kV X-ray. The fading of the phosphors at room temperature was approximately 60% after 20 min.
