The purposes of this study were; 1) to gather data relevant to demographic features. major main management practices, and the level of impairment of the activities of daily living (ADL) of patients with back pain, 2) to test the sensitivity of the Korean Pain Rating Scale and the Graphic Rating Scales, and 3) to identify indirect indicators of back pain by analysing pain related-behaviors. The level of pain was measured by Korean Pain Rating Scale(KPRS) and Graphic Rating Scales(GRS) developed by the reserchers. The GRS consists of two dimensions; the pain intensity (sensory) and unpleasantness (affective) measures. Of the 1,650 diagnosed back pain patients, from January 4 through June 30, 1987 by visiting outpatients' clinics of orthopedic and neurosurgical departments at 11 university hospitals in different districts of Korea, 330 men and women patients were self-selected by responding to the mailed questionnaires. The results were summarised as follows: Male exceeded female patients in number and onset of back pain were more prevalent in the age groups of 20s and the 30s. The average duration of suffering from the pain were 11 months, sixty three (19.1%) of the subjects retired from their jobs, one third(36.7%) have teen hospitalized for the treatment of back pain. In two thirds(64.8%) of the cases pain was characterized as lower back pain. The average sleep hour was 6.8 hours per 24 hours and the average rest hour during the day was 3.3 hours. The mean percentage of pain measured by GRS was higher than that of KPRS. The level of sensory intensity as well as the affective level of pain measured by KPRS and GRS were not highly correlated (sensory intensity r=0.4986, affective r=0.5029) which indicated low discriminative power. On the other hand, intercorrelation between sensory and affective dimension measured by KPRS and GRS showed moderate interrelation(r=0.7247; r=0.7899). One-third(32.5%) of the subjects complied with the hospital prescribed treatment while the other one-third(31.5%) depended on self-remedy and traditional practices, and the last one-third did not imply any pain management practices. The following 6 pain-related behaviors such as length of hospitalization, rest hour during day hours, varieties of pain management practice implied, number of pain sites, need for ADL and discomfort accompanied by ADL revealed to be important indicators of back pain. An investigation of sociodemographic features of patients with back pain in a larger context, i.e. with bigger number of respondents is recommended. Tests for construct validity of KPRS, i.e. factor analysis is further recommended.

Purpose: This study attempted to verify the effect of Koryo hand therapy on menstrual cramps and dysmenorrhea among college students. Method: This study performed the quasi-experimental design with nonequivalent control group and the pre and post-test design from August 28 to November 4, 2002. The subjects of this experimental study consisted of 64 college students in the nursing college of K University in D city and K college students in K city, who had more than 5.0 GRS score of menstrual cramps. Among them, 16 people belonged to the experimental group A by using Ceramic Seo Am moxa therapy, 16 to the experimental group B by using Seo Am pellet therapy, 16 to the experimental group C by using combination of Ceramic Seo Am moxa therapy and Seo Am pellet therapy and 16 to the control group. Three different kinds of methods were used three times per week for $5{\sim}6$ weeks(a total of $15{\sim}18$ times) interventions were completed. For the experimental group, A Ceramic Seo Am moxa therapy was given for 40 minutes per each treatment; for the experimental group, B Seo Am pellet therapy was given for 4 hours: for the experimental group, C combination of Ceramic Seo Am moxa therapy and Seo Am pellet therapy was given. To measure menstrual cramps, the graphic rating scale (GRS) was used and to measure dysmenorrheal, a dysmenorrhea scale (15 contents) was used, which was modified from Han &Hur's scale (13 contents). Cronbach's was 0.78 in the pre-test, 0.83 in the first post-test, 0.89 in the following post-test. Data were analyzed by one-way ANOVA, 2 test, repeated measures ANOVA, time contrast test and Sheffe test with the SPSS/Win 11.0 program. Results: ? The first hypothesis, 'Among the experimental group A by using Ceramic Seo Am moxa therapy, the experimental group B by using Seo Am pellet therapy and the experimental group C by using combination of Ceramic Seo Am moxa therapy and Seo Am pellet therapy will have different graphic rating scores of menstrual cramps', was supported (F=6.77, p=0.000, Interaction: p=0.000). ? The second hypothesis, 'Among the experimental group A by using Ceramic Seo Am moxa therapy, the experimental group B by using Seo Am pellet therapy, the experimental group C by using combination of Ceramic Seo Am moxa therapy and Seo Am pellet therapy and the control group will have a significantly different level of dysmenorrhea', was supported (F=6.88, p=0.000, Interaction: p=0.000). From the above results, it can be an effective nursing intervention to give Koryo hand therapy to college students who have menstrual cramps and dysmenorrhea. Conclusion: These findings indicate that Koryo hand therapy could be applied to improve the quality of life and to prevent drug misuse among college students who are physically, mentally and psychologically suffering from menstrual cramps and dysmenorrhea. Furthermore, Koryo hand therapy could be developed as an effective Korean alternative and complementary care in the future. and it could also provide a guideline to apply Koryo hand therapy to other pain and difficulties.

Because of the increasing need to use clayey soil as the backfill in reinforced soil structures and embankment material, nonwoven geotextiles with the drain capability have been receiving much attention. However, there are few studies of the deformation behavior of nonwoven geotextiles at geosynthetics reinforced soil structures in the field because the nonwoven geotextile, which has low tensile stiffness and higher deformability than geogrids and woven geotextiles, is difficult to measure its deformation by strain gauges and to prevent the water from infiltrating. This study proposes a new, more convenient method to measure the deformation behaviour of nonwoven geotextile by using a strain gauge; and examines the availability of the method by conducting laboratory tests and by applying it on two geosynthetics reinforced soil (GRS) walls in the field. A wide-width tensile test conducted under confining pressure of 7kPa showed that the local deformation of nonwoven geotextile measured with strain gauges has a similar pattern to the total deformation measured with LVDT. In the field GRS walls, nonwoven geotextile showed a larger deformation range than the woven geotextile and geogrid; however, the deformation patterns of these three reinforcement materials were similar. The function of strain gauges attached to nonwoven geotextile in the walls works normally for 16 months. Therefore, the method proposed in this study for measuring nonwoven geotextile deformation by using a strain gauge proved useful.

Purpose: The purpose of this study is to verify the effects of the Qigong training program on the anxiety and labor pains of primipara. Method: The research subjects were a total of 60 primipara who consulted a doctor regularly concerning their antenatal care. Among them, 30 people were the experimental group, and the other 30 people were the control group, and were selected as homogeneous with the experimental group. The degree of anxiety and labor pains were measured by State-Trait Anxiety Inventory(STAI) and Graphic Rating Scale(GRS). SPSS WIN 11.0 was used for data analysis. Obstetric and general characteristics between experimental and control groups, and a homogeneity test of state and trait anxiety were done by both $X^2$ test and t-test. The hypothesis testing was analyzed by ANCOVA with a covariate of pretest value. Result: The first hypothesis, 'Primipara who join the Qigong training program have lower anxiety than those who do not join' was supported (F=28.8, p<.000). The second hypothesis, 'Primipara who join the Qigong training program have lower labor pain than those who do not join' was unsupported. Conclusion: It was verified that the Qigong training program was effective in alleviating anxiety; however it did not have any effect on relieving labor pain, so more in-depth research is needed later on.

도로 성토재 및 구조물 뒤채움재로 점성토 활용의 필요성이 증가함에 따라 보강재로 배수성을 갖고 있는 토목섬유 부직포가 점차 주목을 받고 있으나, 현장 보강토구조물에서 부직포의 변형거동을 분석한 사례는 거의 없으며, 그 이유는 부직포의 경우 지오그리드나 직포에 비해 강성이 작고 변형률이 크며 스트레인 게이지를 이용한 계측이 곤란하기 때문이다. 본 연구에서는 스트레인 게이지를 이용하여 부직포의 변형거동을 보다 간편하게 계측할 수 있는 방법을 제안하였고, 이를 실내시험과 2개의 실물보강토옹벽에 적용하여 유용성 여부를 검토하였다. 구속압 70kPa 하에서 실시한 실내 광폭인장시험의 경우 스트레인 게이지에 의해 계측된 부직포의 국부변형은 LVDT에 의해 계측된 전체변형과 유사한 패턴으로 거동하는 것으로 나타났다. 실물보강토옹벽에서 부직포의 변형범위는 직포나 지오그리드보다 크게 나타나나, 이들 보강재와 변형 패턴이 유사하고, 16개월 동안 정상적으로 작동하는 것으로 나타났다. 따라서, 본 연구에서 제안한 스트레인 게이지에 의한 부직포의 변형계측방법은 매우 유용한 것으로 판단된다.

This paper presents an investigation into the operational comparison of SPOT triangulation to build GCP library by analytical plotter and DPW (digital photogrammetric workstation). GCP database derived from current SPOT images can be used to other image sensors of satellite, if any reasons, such as lack of topographic maps or GCPs. But, general formulation of a photogrammetric process for GCP measurement has to take care of the scene interpretation problem. There are two classical methods depending on whether an analytical plotter or DPW is being used. Regardless of the method used, the measurement of GCPs is the weakest point in the automation of photogrammetric orientation procedures. To make an operational comparison, five models of SPOT panchromatic images (level 1A) and negative films (level 1AP) were used. Ten images and film products were used for the five GRS areas. Photogrammetric measurements were carried out in a manual mode on P2 analytical plotter and LH Systems DPW770. We presented an approach for exterior orientation of SPOT images, which was based on the use of approximately eighty national geodetic control points as GCPs which located on the summit of the mountain. Using sixteen well-spaced geodetic control points per model, all segments consistently showed RMS error just below the pixel at the check points in analytical instrument. In the case of DPW, half of the ground controls could not found or distinguished exactly when we displayed the image on the computer monitor. Experiment results showed that the RMS errors with DPW test was fluctuated case by case. And the magnitudes of the errors were reached more than three pixels due to the lack of image interpretation capability. It showed that the geodetic control points is not suitable as the ground control points in DPW for modeling the SPOT image.

세계측지계의 도입에 따라 광범위한 공간데이터의 재정비가 필요하게 되었다. 이 연구에서는 이를 위한 통합모델로서 상호운용성과 표준화 및 공간 DB 활용에 기반한 구체적인 전략과 시범시스템을 제시한다. 세계측지계를 위한 지도데이터 변환은 파일변환과 공간DB 변환, 그리고 파일-공간DB 상호간 변환의 형태로 이루어질 수 있다. 이 연구에서 개발한 통합모델은 기존의 파일형식(예컨대, DXF와 Shapefile)은 물론 새로운 표준으로 권장되는 파일형식 (예컨대, GML과 SVG)의 세계측지계 변환이 파일형식 상호간에 이루어지도록 한다. 이러한 지도파일들은 세계측지계 변환모듈을 거쳐 공간DB로 임포트되거나 공간DB로부터 익스포트 될 수 있다. 또한, 공간DB의 세계측지계 변환은 단일 DB 내부변환과 함께 이질적인 DB간의 변환 (예컨대, SDE/Oracle과 Oracle Spatial)을 포함한다. 이 연구의 세계측지계 변환시스템은 다중컴퓨팅 환경을 고려하여 데스크탑과 인터넷 기반에서 동시에 운영되도록 구현되었다. 시험운영과 평가를 통해 본 연구에서 제안한 통합모델의 상호운용성과 타당성이 검증되었으며 또한 좌표변환의 결과도 기존 연구의 결과물과 일치함을 확인하였다.
