  • Purpose: This study was conducted to evaluate the need for education for emergency care in nursing homes. Method: 312 people who were engaged in caring for the elderly at nursing homes in D-metropolitan c! ity answered the questionnaires about the experiences, the need, and the ideal methods of education for basic emergency care, from Jul. 1. 2007 to Jul. 30. 2007. Result: 69.9% were female. Only 7.1% were nurses and the rest did not have majors in the medical field. 83.0% had experienced education for emergency care, and 89.2%, 78.4% and 44.8% of them had been educated about cardiopulmonary resuscitation, airway obstruction care, and fracture/sprain/dislocation care respectively. Fifty-three who had not experienced education answered 'no opportunity' as a cause of non-education. The need for emergency care education was 4.53/5.00, and the desire to receive education was 2.81/3.00. Mainly workers wanted to be educated abo! ut airway obstruction (88.1%), and breathing assistance & cardiac massage (72.4%). Workers preferred to be educated 1-2 times per year for 2-3 subjects, through programs including both lecture and practice. Conclusion: It is essential to create an adequate program and apply it to the people engaged in caring for the elderly.

  • Y2O3 thin films were deposited by reactive sputtering of Y target in Ar and O2 gas mixture. Residual stress was measrued by sin2$\psi$ method of x-ray diffraction (XRD) and growth orientation was examined by measuring the relative intensity of (400) plane and (222) plane of Y2O3 films. In the case that Y2O3 films were deposited at 40$0^{\circ}C$ and at low working pressure below 0.05 torr the film had large compressive stress and (111) plane orientation. At working pressure of about 0.10 torr the film had small compressive stress and (100) orientation. Above working pressure of 0.20 torr, the films had nearly zero stress and random orientation. In the case that the (111) oriented film deposited at low working pressure below 0.05 torr, as substrate temperature decreased, (111) orientation increased. In the case the film, with (100) orientation, deposited at working pressure of about 0.10 torr, (100) orientation increased with decresing substrate temperature. These relationship of residual stress and growth orientation can be explained by the relationship of surface energy and strain energy.

  • Objectives : The purpose of this study was to investigate the toll-like receptor (TLR)-4 mediated anti-inflammatory effects of extract from Shigyungbanha-tang (SBT) on the peritoneal macrophage. Methods : To evaluate of TLR-4 mediated inflammatory of SBT. we examined NO and cytokine production in TRL-4 ligand (LPS : lipopolysaccharide) induced macrophages. Furthermore, we examined its molecular mechanism using western blot. Results : Extract from SBT itself does not have any cytotoxic effect in the peritoneal macrophages. Extract from SBT reduced LPS-induced nitric oxide (NO). tumor necrosis factor-alpha ($TNF-{\alpha}$), interleukin (IL)-6 and IL-12 production in peritoneal macrophages. SBT inhibited degradation of inhibitor kappa B-alpha ($I{\kappa}B-{\alpha}$) in the TLR-4 mediated peritoneal macrophages. Conclusions : These results suggest that SBT inhibits NO and cytokines production through inhibiting nuclear factor-kappaB (NF-${\kappa}$B) activation in peritoneal macrophage and that SBT may be beneficial oriental medicine for inflammation.

  • Pneumonia is an inflammation that forms at the mesopulmonum and alveolus that is also an acute infection with fever and cough. It is difficult for doctors to diagnose pneumonia in elderly patients, due to the variety of symptoms. For this reason, it, with its complications, is a major cause of death for the elderly. In this case, improvement was seen in an elderly patient diagnosed with pneumonia by X-ray, and by using Si-Kyung-Ban-Ha-Tang-Ka-Mi-Bang as a way of Kong-Bo-Kyum-Si, because in this case pneumonia was presumed Dam-Yel-Ong-Pye and Ki-Eum-Yang-Huh due to the weakness associated with old age. This thesis proposes that the elderly are better treated differently from other pneumonia patients due to the weakness that comes with old age.

  • Purpose: This study was conducted to investigate how information using leaflet will affect anxiety of inpatients undergoing endoscopic examination. Methods: Non-equivalent control group with a pre-post test design was used. Subjects were selected from inpatients of D hospital in B city for endoscopic examination from May 1 to July 31, 2009. Forty subjects were assigned to either control or experimental group. The Leaflet developed by authors was used as an educational material. Johnson's visual analogue scale, blood pressure, and pulse were used to measure anxiety. Results: The experimental group informed with the leaflet showed less subjective anxiety than control group without the leaflet (p=.008). Experimental group informed with the leaflet showed less objective anxiety measured by systolic blood pressure, diastolic blood pressure, and heart rate than control group without the leaflet (p=.004, .014, and .009, respectively). Conclusion: Giving information using leaflet to the patient before endoscopy may be applicable as a nursing intervention to reduce anxiety. Further studies are needed to generalize the results of this study.

  • The objectives of the unit ‘Family Relations’in high school Home Economics Education is to help the students cultivating proper values and self-esteem, maintaining harmonious personal relations not only by understanding human relationships in family, but also by acquiring role play, and is to wisely cope with many problems occurring in social life, which are indispensable for those living in modern society. But at present it is hard for the students to gain those abilities mentioned above, for the present unit ‘Family Relations’lays special emphasis only on memorizing specific knowledge about the understanding of a family. To improve the present educational situation, this study develops a new teaching-learning method based on the role play model concerning the ‘Family Relation’area of high school Home Economics Education curriculum. This study is theoretically based on the literature and previous studies on present problems of our various family relations, and solving its problems, and suggests lesson model of role play and its effect. This study was performed as following procedures: the ‘Family Relation’unit of the present high school Home Economics Education curriculum was analyzed, and surveyed students to discover the conflicts and their solutions the high school students are now experiencing in their family relations. Accordingly, a new lesson model of the ‘Family Relation’area, applying role play was developed. Based on the developed lesson plan, two-hour classes were experimented and positive evaluation was given by students.

  • Tin-doped In2O3 (ITO) films were fabricated using a d.c. magnetron reactive sputteirng of a In-10 wt% Sn alloy target in an Ar and O2 gas mixture. To understand the behavior of the carrier mobility in ITO films with O2 partial pressure, the resistivity, carrier concentration and mobility, film density, and intrinsic stress in the films were measured with O2 partial pressure. It was found experimentally that the carrier mobility increased rapidly as the film density increased. In the ITO film with the density close to theoretical one, the mean free path was the same as the columnar diameter. This indicated that the mobility in ITO films was strongly influenced by the crystall size. However, in the case where the film density was smaller than a theoretical density, the mean free paths were also smaller the columnar diameter. It was analyzed that the electron scattering at pores and holes within the crystalline was the major obstacle for electron conduction in ITO films. The measurement of intrinsic stress in ITO films also made it clear that the density of ITO films was controlled by the bombardment of oxygen neutrals on the growing film.

  • PbTiO3 thin films were fabricated onto MgO(100) single crystal substrate by reactive D. C magnetron sput-tering of Pb and Ti metal in an oxygen and argon gas mixture. The annealing of the thin films resulted in the decrease of both the c-axis orientation ratio and the lattice parameter. It is well known that the c-axis lattice parameter of thin film is dependent on the Pb/(Pb+Ti)ratio and the residual stress in the film The PbTiO3 thin films with a Pb/(Pb+T) ratio ranging from 0.45 to 0.57 were fabricated and annealed. The structure of the film the c-axis orientation ratio and the lattice parameter were not dependent on the Pb/(Pb+Ti) ratio before and after annealing. These experimental results proved that the decrease of the c-axis lattice parameter under the annealing conditions was due to the relaxation of the intrinsic stress in the film. This relaxation of the intrinsic stress caused the decrease of the c-axis orientation ratio and this phenomenon can be explained by c-axis growth lattice model.
