This study was performed to identify the level of stress recognized by the parents as a support system for their infant patients who were hospitalized in an emergency department, thus to provide the resulting data as the basic material of care intervention for the families of infant patients. This study subjected the parents with infant patients who were hospitalized in emergency department of C University Hospital in Daejeon, and the data was collected from questionnaires for them, dating from Mar. 20, to Jun. 24, 2001 This study used the tool(30 questions) which was originally developed by Ji, Dong-ok (1992) for measuring the stress of families of infant patients in emergency room, and then was modified and complemented by this researcher suitably for infant patients. Collected data was statistically analyzed with frequency, percentage, mean, standard deviation, t-test, ANOVA, by using SPSS WIN10.0 program, and the results were as follows: 1. The stress of parents with infant patients hospitalized in emergency department averaged 3.31 on the basis of 5-point measure, which means that they felt stress beyond means. 2. The factor with high average out of stress factors the parents of infant patients recognized included the followings: 'about the pain of infant patients due to examination(3.91±1.00)'; 'about rare opportunity to be in contact with physician(3.78±1.09)'; 'delay in emergent treatment required for infant patients(3.75±1.31)'; 'delay in the general treatment of infant patients(3.72±1.32)'. Factors of the stress level includes the followings: 'care and medical treatment'(3.46±.72); 'body and diseases'(3.41±.97)'; 'lack of information and supportable resources (3.25±.77)'; and so on. 3. For the stress level according to general characteristics, there were statistically significant differences in the result of the condition of infant patients, medical treatment(P<.01), religion, the procedure of treatment(P<.05). With little preceding studies for infant patients hospitalized in emergency department, this study looked through the level of stress recognized by the parents of infant patients. Based on the comprehension on the parents with infant patients and the knowledge on stress factors recognized by the parents, it is expected that we can seek the methods of care intervention such as explanation of care and treatment procedures, unit policies, continuous interest and emotional supports as well as the provision of information to understand the responses of parents and reduce accompanied stresses.

Rheumatoid arthritis(RA) is a general, chronic, inflammatory and auto-immune disease and it can lead to joint edema, pain, stiffness which are caused by an inflammation in synovium covering our joints. Ulmus davidiana Planchon is a traditional herb used for the treatment on various inflammations, gastrointestinal trouble, ENT(ear, nose, and throat) disease, edema, cancer etc. and it works effectively on arthritis as well. In these study to search for the treatment efficacy of Ulmus davidiana Planchon in RA, I measure manifestation of cytokine gene in synoviocyte treated with Ulmus davidiana Planchon herbal acupuncture and in EL-4 cell, manifestation of cytokine gene cell related to T-cell. And after Ulmus davidiana Planchon herbal acupuncture treatment in Collagen induced arthritis(CIA) which has been known by a general model of RA, DBA mice, I observed foot thickness, general shape of synovium, early cytokine induce CIA and, generation and mutation of cytokine related to the control of T-cell specialization. It comes to conclusion as belows. 1. In synovium treated with Ulmus davidiana Planchon herbal acupuncture, there was the decrease in MIF mRNA does-dependently. Incase of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in the damage in synovium and generation of the MIF which is related to induction of the early RA cytokine and IL-6 proinflammatory cytokine. 2. In case of EL-4 treated with Ulmus davidiana Planchon herbal acupuncture, there were decrease in the manifestation of the IL-2 mRNA, but the increase in the manifestation of the IL-4 does-dependently. 3. In the synovium of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in generation of IL-2, IL-12 and CD-28, but the increase in generation of IL-4. These result suggest that Ulmus davidiana Planchon can block the process of the early RA by Inhibiting MIF activation, and mitigate Rheumatoid Arthritis by controlling Tcell specialization.

The purpose of this study was to investigate the stress response of nurses working on psychiatric wards (psychiatric nurses) compared with that of nurses working on general wards (general nurses) in order to provide assessment data for intervention of the stress response. The Symptoms of Stress Inventory was used to measure the stress response. Data were collected by a direct survey method using a questionnaire and were collected from March first to March 30, 1995. A sample of 200 nurses working in three psychiatric hospitals and psychiatric wards in four university hospitals in Seoul and Kangwon province were selected and 200 nurses working on general wards from two general hospitals in Seoul were also selected for a total sample of 400 nurses. Nurses who had experienced more than one of the major life events in the last two years were excluded from the total number in the samples, so the final sample was 161 psychiatric nurses, and 169 general nurses. The Scores for the total stress response, scores of the SOS subscales, stress response by sociodemographic characteristics of the nurses working on the psychiatric wards were compared with those of nurses working on the general ward. The results of this investigation are as follows 1. The mean total SOS score for the psychiatric nurse was 0.81 (SD=0.48) and that of the general nurses was 0.90(SD=0.53). 2. The Mean score for peripheral manifestation, con tral-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, de-pression, anxiety, anger and cognitive disorganization for the general nurses showed a tendency to be higher than those of the psychiatric nurses. Mean score for cardiopulmonary symptoms for the general nurses was significantly higher than that of the psychiatric nurses. 3. The mean scores for the sixteen SOS items for the general nurses was significantly higher than for the psychiatric nurses. The 16 items were flushing of the face, sweating excessively even in cold weather, thumping of the heart, rapid breathing, dry mouth, a choking lump in the throat, hoarseness, muscle tension in hands or arm, muscle tension in leg, working tiring one out completely, severe aches a핀 Pain make it diffi-cult to do the work, severe nervous exhaustion, worrying about health, feeling weak and faint, so upset that one wants to hit something, unable to keep thoughts from running through one's mind. The mean score of only 505 item were significantly higher for the psychiatric nurses. 4. Stress responses between psychiatric nurses and general nurses were significantly different according to the following demographic characteristics : marriage, duration of work, position, accommodation, planning to move into another working site, working ward, education in psychiatric nursing.

This study was designed to identify, describe and classify orientations of cancer patient's family members to death and to identify factors related to their attitudes on death. Death to the male is understood as a comprehensive system and believed to be highly subjective experience. Therefore attitude on death is affected by personalities. As an attempt to measure the subjective meaning toward death, the unstructured Q-methodology was used. Korean Death Orientation Questonaire prepared by Kim was used. Item-reliability and Sorting-reliability were tested. Forty five cancer patients' family members hospitalized in one university medical center in Seoul were sampled. Sorting the 65 Q-itmes according to the level of personal agreement ; A forced normal distribution into the 11 levels, were carried out by the 45 P-samples. The demographic data and information related to death orientation of the P-sample was collected through face to face in depth interviews. Data was gathered from August 30 till September 22, 1995. The Z-scores of the Q-items were computed and principal component factor analysis was carried out by PC-QUANL Program. Three unique types of the death orientation were identified and labeled. Type I consists of twenty P-samples. Life and death was accepted as people's destiny, They firmly believed the existence of life after life. They kept aloof from death and their concern was facing the and of the life with dignity, They were in favor of organ donation. Type II consists of Nine P-Samples. They considered that death was the end of everything and did not believed the life after life. They were very concerned about the present life. Type III consists of Sixteen P-samples. They regarded the death as a natural phenomena. And they considered that the man is just a traveller and is bound to head for the next life which is believed to be free of agony, pain or darkness. They neither feared death nor its process. Their conserns were on the activities to prepare themselves for the eternal-life after death. Thus, it was concluded that there were three distinctiven type of attitudes on death among cancer patient family members, and their death attitudes were affected by demographic and socio-cultural factors such as sex, education, and religion.

Objective : Percutaneous pedicle screw (PPS) fixation is a needle based procedure that requires fluoroscopic image guidance. Consequently, radiation exposure is inevitable for patients, surgeons, and operation room staff. We hypothesize that reducing the production of radiation emission will result in reduced radiation exposure for everyone in the operation room. Research was performed to evaluate reduction of radiation exposure by modifying imaging manner and mode of radiation source. Methods : A total of 170 patients (680 screws) who underwent fusion surgery with PPS fixation from September 2019 to March 2020 were analyzed in this study. Personal dosimeters (Polimaster Ltd.) were worn at the collar outside a lead apron to measure radiation exposure. Patients were assigned to four groups based on imaging manner of fluoroscopy and radiation modification (pulse mode with reduced dose) : continuous use without radiation modification (group 1, n=34), intermittent use without radiation modification (group 2, n=54), continuous use with radiation modification (group 3, n=26), and intermittent use with radiation modification (group 4, n=56). Post hoc Tukey Honest significant difference test was used for individual comparisons of radiation exposure/screw and fluoroscopic time/screw. Results : The average radiation exposure/screw was 71.45±45.75 µSv/screw for group 1, 18.77±11.51 µSv/screw for group 2, 19.58±7.00 µSv/screw for group 3, and 4.26±2.89 µSv/screw for group 4. By changing imaging manner from continuous multiple shot to intermittent single shot, 73.7% radiation reduction was achieved in the no radiation modification groups (groups 1, 2), and 78.2% radiation reduction was achieved in the radiation modification groups (groups 3, 4). Radiation source modification from continuous mode with standard dose to pulse mode with reduced dose resulted in 72.6% radiation reduction in continuous imaging groups (groups 1, 3) and 77.3% radiation reduction in intermittent imaging groups (groups 2, 4). The average radiation exposure/screw was reduced 94.1% by changing imaging manner and modifying radiation source from continuous imaging with standard fluoroscopy setting (group 1) to intermittent imaging with modified fluoroscopy setting (group 4). A total of 680 screws were reviewed postoperatively, and 99.3% (675) were evaluated as pedicle breach grade 0 (<2 mm). Conclusion : The average radiation exposure/screw for a spinal surgeon can be reduced 94.1% by changing imaging manner and modifying radiation source from real-time imaging with standard dose to intermittent imaging with modified dose. These modifications can be instantly applied to any procedure using fluoroscopic guidance and may reduce the overall radiation exposure of spine surgeons.

Harnesses are used in a variety of industries, such as rescue operations, medicine, and entertainment. However, conventional harnesses have problems as they are uncomfortable to wear and causes continuous pain. Therefore, in this study, the load and pressure applied to the body in the flying state when using a conventional harness were measured in real time and the distribution change was observed. Load and pressure were measured using a modified corset harness, a pressure sensor, and a human mannequin to measure the maximum and average pressure on the waist. As a result, it was confirmed that the load concentrated on the waist in the flying state was 104 N, and the pressure was applied to the left and right sides was 800 kPa or greater. The pressure distribution showed a pressure of 3-45 kPa in 73% in all measurable pressures. The results of the load and pressure distribution are presented as basic data for improving the wearability and reducing the discomfort of harnesses in the future, aid in the development of a harnesses that can minimize discomfort for various activities, and increase the concentration on experiential activities. In addition, using the CLO 3D program, which is a 3D virtual wearing system, a harness was put on a virtual model, and the compression level was checked and compared with the actual pressure distribution. As a result of comparing the measured pressure values in the flying state with the clothing pressure wearing the harness in the CLO 3D program, the total pressure value was found to be about 68% of the actual measured value. This helps develop a harness that can minimize discomfort during activities by predicting the load and pressure on the body by first applying new designs to a virtual wearing system during development. These new harness patterns can solve the problems of conventional harnesses.

Objective: The purpose of this study was to investigate the muscle activity ratio of the lower limb according to changes in straight leg raise (SLR) test angles on hamstring muscle shortening during squat exercises. Design: Randomized controlled trial. Methods: The subjects were 14 healthy adults who were informed of and agreed to the method and purpose of the study. The participants were classified into SLR groups according to two angles (over $80^{\circ}$ or under $80^{\circ}$) assessed using the SLR tests. After training and practicing the wall squat posture to be applied to the experiment, electromyography (EMG) was used to measure changes in muscle activity during the performance of a wall squat. After stretching, a sequence of pre-stretch tests were performed again, and the active and passive SLR tests were also reconducted; thereafter, a wall squat was performed again by attaching EMG electrodes. The EMG results before and after stretching were compared. Results: The muscle activity of the vastus lateralis oblique muscle increased in both groups. The muscle activity of the vastus medialis oblique muscle decreased in over both group. Rectus femorus activity increased in the under 80-degree groups but decreased in the over 80-degree group. The muscle activity of the biceps femoris muscle decreased after stretching in the over 80-degree group and increased in the under 80-degree group, and the semitendinosus muscle activity after stretching was decreased. The quadriceps-to-hamstring muscle (Q:H) ratio before and after stretching between groups showed that the hamstring muscle ratio decreased after stretching in both groups. Conclusions: The results of this study showed that the Q:H ratio before and after stretching between groups was not significantly different.
