Purpose: Most of postoperative patients experience pain, state anxiety and sleep disturbance. These problems negatively influence the recovery of postoperative patients. So alleviating these problems has been one of the nurses' central roles. The purpose of this study was to examine the effects of back massage on pain, state anxiety and quality of sleep of postoperative gastrectomy patients. Methods: A non-synchronized non-equivalent control group pre and post-test design was used. The research instruments used in this study were the Numerical Rating Scale (NRS) for pain, the State-Anxiety Inventory (STAI) for anxiety and the Verran and Synder-Halpern scale for quality of sleep. The subjects were patients admitted to a university hospital located in D city. Twenty-nine patients in the experimental group had a 10 minute manual back massage stimulation for 5 days from the 1st day to the 5th day after their operation, and 25 patients in the control group did not. Results: The degree of pain was significantly reduced according to post operation day and quality of sleep was significantly increased. However state anxiety was not significantly reduced. Conclusion: Back massage is a partially effective nursing intervention for postoperative patients with gastrectomy who experience pain and sleep disturbance.

본 연구에서는 각종 합성 강상자형 도로교에 대한 체계신뢰성 및 이에 기초한 내하력평가를 위하여 실용적이고 합리적인 신뢰성 모형과 해석방법을 개발하고자 한다. 합성 강상자형교의 신뢰성해석을 위해서는 휨강도 뿐만 아니라 휨, 전단 그리고 비틀림을 동시에 고려한 강도식에 기초하여 한계상태함수를 모형화 하였으며, 체계신뢰성 문제는 각 거더의 주요 파손기구에 기초한 FMA(Failure Mode Approach)방법을 사용하여 직 병렬 조합체계로서 정식화 하고 수치해석기법인 중요도표본추출기법(Importance Sampling Technique ; IST)을 사용하여 해석하였다. 특히 본 연구에서는 추정된 체계신뢰성지수를 일반적인 제 1계 2차모멘트(First Order Second Moment ; FOSM)방법의 형태로 표현하여 유도한 등가의 시스템 내하력으로서 합성 강상자형교의 내하력을 평가하는 실질적이고 합리적인 방법을 제안하였다. 기설 교량에 대한 내하력 및 안전도평가 결과 전체시스템으로서의 보유안전도와 내하력은 교량의 부정정성이 높아질수록 개별 요소의 경우에 비해서 그 차이가 크게 됨을 알 수 있었으며, 제안된 체계신뢰성에 기초한 내하력평가 방법은 기설 합성 강상자형교의 실질적인 내하력평가 방법을 위하여 합리적으로 사용될 수 있을 것으로 사료된다.

This paper describes the development of the database system for tunnel management of Korea National Railways. In order to make the system both target independent and accessible by KNR network or modem, authors developed the system as a web-based application using java language and IBM DB2 database. The system includes the searching, reporting, graphical representation and statistical functions for tunnel data, maintenance records and checking records. Later, the system will be extended to include the process for tunnel state rating and maintenace prioritiy decision-making.

This study was designed and undertaken to identify objectively the degree and relationship of anxiety, depression which are chief essential elements of emotional status in Stroke medical examination patients. The subjects in this study were 58 Stroke medical examination patients and 58 Non-Stroke medical examination patients, and for the assessment of anxiety, depression. We used State-Trait Anxiety Inventory (STAI), Zung's Self-Rating Depression Scale(SDS). The results of this study are as follows : 1. There were significant, differences in the 16 items of State anxiety scale among 20 items and the 14 items of Trait anxiety scale among 20 items between Stroke medical examination patients and the control group(p<0.05 respectively). 2. There were significant differences in the 14 items of SDS among 20 items between Stroke medical examination patients and the control group(p<0.05 respectively). 3. There were significant differences in the mean scores of STAI and SDS between Stroke medical examination patients and the control group(p<0.001 respectively). 4. There were no significant relationships between State anxiety & Trait anxiety, State anxiety & Depression, Trait anxiety & Depression in the Stroke medical examination patients.

Objective: To compare the influence of breast-conserving surgery (BCS) and modified radical mastectomy (MRM) on the psychological state of breast cancer patients. Methods: Patients receiving MRM or BCS, and fulfilling the study criteria, were recruited. Patients were required to complete a self-reporting inventory (SCL-90) on admission and 6 months after surgery and a self-rating depression scale (SDS) when discharged from hospital and 6 months after surgery. Results: A total of 70 patients received MRM and 50 BCS. Compared with the national standard, patients suffered to some extent psychological problems on admission, at discharge from hospital and at 6 months after surgery. Patients received BCS had a higher score of SDS compared with those with MRM when discharged from hospital. However, 6 months after surgery, SDS score increased in MRM and decreased in the BCS group, so the difference was significant. Conclusion: The short-term psychological state of patients receiving BCS is worse than that with MRM but superior to MRM 6 months postoperatively. BCS imposed less influence on long term psychological state of breast cancer patients compared with MRM.

In Korea, the pilot construction of the first high-speed railroad on the Seoul-Pusan has already started 2 years ago. In the thesis, an attempt is made to develop reliability-based integrity-assessment models for the computer-aided control and maintenance of high-speed railroad bridges. The strength limit state models for PC railroad bridges encompass the bending and shear strengths as well as the strength interaction equations which simultaneously take into the element and system reliablities of the proposed limit states and reliability models. Then, the actual load carrying capacity and the realistic safety of bridges are evaluated using the system reliability-based equivalent strength, and the results are compared with those of the element reliability-based or conventional methods. Various parametric studies are performed for the proposed reliability-based safety and integrity-assessment models using the actual PC box girder bridges used in the pilot construction. And the sensitivity analyses are performed for the basic random variables included in strength limit state models. It is concluded that proposed models may be practically applied for the rational assessment of safety and integrity of high speed railroad bridges.

We experienced a 71year-old man who had a traumatic subdural hemorrhage as well as delirium, and whose condition was improved through oriental medical treatment. Herbal medicine Hwaeo-jeon is administered three times a day. We did Mini-Mental State Examination-Korean(MMSE-K) and Korean-Dementia Rating Scale(K-DRS). After being treated, the patient showed that symptoms of delirium(diminished or altered state of consciousness, impairment of cognitive abilities or physical function) was improved considerably. This result suggests that Hwaeo-jeon has good effects on delirium with Traumatic Subdural Hemorrhage.

A new 3-phase line-interactive UPS(Uninterruptible Power Supply) system with parallel-series active power-line conditioning capability using AC line reactor and two four-leg PWM VSCs(Voltage Source Converters) was introduced recently. In this paper, the strategy of voltage control in suggested UPS system is explained. The objective of proposed voltage controllers in parallel(shunt) and series PWM VSC is to guarantee satisfactory characteristics in steady state and transient state. Therefore the experimental results to prototype UPS system having power rating of 60kVA is shown to prove the verification of voltage control strategy.

Residual Deformation Analysis(RDA) is a new method for ratings of the continuous bridges. The RDA makes it possible to expand the inelastic steel girder bridge design method set forth in the American Association of State Highway Officals'(AASHTO) Guide Specifications for Alternate Load Factor Design Procedures for Steel Beam Bridges Using Braced Compact Sections(1986) into an inelastic rating method. It is a method to assess the residual moments and deformations that are set up in a beam that has been loaded into the post-elastic range This method combines classical elastic conjugate beam theory with linear moment-rotation relationships for midspan inelastic positive moment. The limit state is inelastic serviceability limit. which is defined as the ratio of the span to midspan inelastic deflection(C=L/D).
