      • 강인성을 주요 개념으로한 이론 합성의 일례 : focal concept: hardiness

        김영옥 서강정보대학 1999 산업과학연구 Vol.1 No.-

        This study was conducted to provide the more sophisticated relationships between hardiness and hardiness-related concepts through theory synthesis, one of theory development strategy. Theory synthesis was based on empirical evidences from published research findings. Literatures for study were collected by Medline search. Criteria for sampling was purposeful sampling limited to research to investigate the effects of hardiness between stress-health relationship, and finally 29 research articles were analyzed. Theory synthesis processes were follows ; First, determine the factors related to hardiness concept through literature review, and classified these factors into determinants and results. Second, collect the representative listing of relational statements pertinent to hardiness. third, collapse highly similar concepts into more comprehensive summary concepts, and then construct the hypothesized conceptual model by diagrammatically mapping the relationship among summary concepts. Finally, extract the statements from conceptual model, and specified each concept of statement into empirical indicator to represent the possibility the empirical testing.

      • 잡음환경에서 구름 볼 베이링의 결함검출을 위한 ALE의 적용

        김영태,최만용,김기복,박해원,박정학,김종억,류준 한국공작기계학회 2004 한국공작기계학회 추계학술대회논문집 Vol.2004 No.-

        It is very important to detect the bearing defects in rotating machinery since the critical failure of bearing cause a machinery shutdown. However it is difficult to detect the vibration signal resulting from the initial defects of bearing because of the high level of broadband noise. A signal processing technique, called the adaptive line enhancer(ALE) as one of adaptive filter, is studied in this work. This technique is to eliminate broadband noise without a prior knowledge of the noise and signal characteristics. Also we propose the optimal methods for selecting the three main ALE parameters such as correlation length, filter order and adaptation constant used in the adaptative process. Vibration signals for three abnormal bearings, including inner and outer raceways and ball defects, were acquired from Anderon(angular derivative of radius on)meter. The experimental results showed that the proposed technique can reliably detect the bearing defective signals masked by broadband noise.

        This study was conducted to identify the relationships between perceived heath status, hardiness, and health promotion behavior among nursing students, and to identify predictors of health promotion behavior. The research subjects were 213 nursing students of one college in Gwangju. Self-reported questionnaires were composed of the Heath Perception Questionnaire, the Health-Related Hardiness Scale, and the Health Promotion Lifestyle Profile, and 4 items asking general characteristics. Data analysis was done with a SAS program. The results of this study were as follows ; 1) According to school year, health promotion behavior showed statistical significant differences (F=5.65, p=.0041). Typically 3-year students have higher score than one and two-year students by Scheffe testing. Also there was a statistical significant differences in challenge and committment between one and three-year students, so three-year subjects have higher degree than one-year students. 2) Perceived heath status, hardiness, and health promotion behavior showed significant correlations with satisfaction about nursing department. 3) Significant correlations between perceived heath status, hardiness, and health promotion behavior were observed. 3) In stepwise multiple regression, 37.44% of the variance in health promotion behavior was accounted for by hardiness(34.76%), and perceive heath status (2.68%). Among subscles of hardiness, challenge and committment were significant predictors, so challenge, committment, and perceived heath status explained 40.53% of variance in health promotion behavior.

      • 강인성(HARDINESS)에 대한 개념분석

        金英玉 서강정보대학 1993 論文集 Vol.12 No.-

        In this paper, Hardiness that reflects one aspect of human personality was selected and analyzed to clarify the defining attributes, characteristics, and to propose theoretical definition of the concept. The Walker & Avant strategy was used together with the theoretical phase of Hybrid model by Schwartz-Barcott & Kim to complete the concept analysis through literature review. The results of this analysis demonstrated that hardiness personality functions as a health-mediating resource that buffers stress effects and motivates desirable health behaviors in the encounter with stressful life events. Based on the results, the theoretical definition and the defining attributes of hardiness personality was suggested. The concept can be defined as follows : Hardiness is an important psychological health-promoting resource that mediates an individual's responses in stressful situations. It is also personality characteristic that leads the individual to perceive stressful life events as an opportunity for one's growth and development, to participate in the situation actively with interest and meaning, and to exercise the one's beliefs of decision-making for problem solving. The defining attributes of Hardiness are as follows : 1) It is trait-oriented personality that functions stress-resistance factor. 2) It accepts changes positively. 3) It has self-transcendence that overcomes the difficult situation. 4) It demonstrates growth-oriented behaviors. This analysis demonatrated the importance of individual's involvement in stress management. Hardiness personality is inherent health-promoting factor in stress-laden human environment. Ultimately, this understanding will provide the essential "building block" for planning, implementing, and evaluating client's stress management program in various nursing situations.

        지리정보 시스템은 수치화된 지리데이타를 화면으로 mapping시키고, 지리테이타와 그의 속성정보를 연계시킬 수 있는 초보적인 기능이 필요하다. 본 논문에서는 이러한 기능을 가진 지리정보 시스템을 구현하기 위한 방법을 제안하였다. 그리고 실제 울산시의 수치지도를 제작하고 업종별 전화번호부를 데이타베이스화하여 울산 지리정보 시스템을 구현하였다. 울산 지리정보 시스템은 수치화된 지번데이타와 업종별 전화번호부의 주소를 연계시켜, 질의된 해당 시설물이나 상호의 주소 위치를 지리테이타와 함께 화면으로 mapping시키는 지리정보 시스템의 응용 프로그램이다. GIS(Geographic Information System) needs two fundamental functions : a mapping function which maps a vetorized geographic data to screen and a relating function which associates the geographic data with their attribute information. This paper proposes a method to design the GIS which has the fundamental functions and implements an Ulsan GIS(UGIS). The UGIS consists of a vectorized Ulsan geographic data and a telephone database of business category. The UGIS associates a lot number in the Ulsan geographic data with an address in the telephone database, and maps an address of major building or a name of business queried to screen with the Ulsan geographic data.

      • 병원 일반간호사의 강인성과 직업적 스트레스 및 소진현상과의 관계

        김영옥 서강정보대학 2001 論文集 Vol.20 No.-

        This study was designed to investigate the relationships of hardiness, job stress, and burnout and to identify predictors of burnout in nurses. Empirical data were collected from 154 staff nurses at one university hospital in Gwangju city. Self-reported questionnaire was composed of the Personal Views Survey(PVS), job stress scale, Tedium scale, and 6 items asking nurse' s general characteristics. Data analysis was done with SAS package. In correlation analysis, hardiness, job stress, and health status have significant correlation with burnout. In stepwise multiple regression, 25.3% of the variance in burnout was accounted for by job stress(12.4%), health status(7.1%), and hardiness(5.7%). Among subscales of hardiness, commitment was the only significant predictor, so job stress, hardiness, and commitment explained 25.6% of variance in burnout.

      • PCR을 이용한 Rat 기관지 세척액에서의 Pneumocystis carinii DNA의 검출 : 기초실험 A pilot study

        김주옥,홍석철,한표성,이종진,김선영,이영하,신대환 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.1

        Background: Pneumocystis carinii (PC) is a opportunistic pathogen causing serious pneumonia (Pneumocystis carinii pneumonia : PCP) in immunosuppressed patients including AIDS. Laboratory diagnosis of PCP is dependent on microscopic demonstration of the PC by using cytochemical staining or by immunocytochemical staining with monoclonal antibodies. However, these staining methods are not highly sensitive. The development of the polymerase chain reaction (PCR) has made it possible to detect very small numbers of pathogens in clinical specimens. To establish the usefulness of PCR for detection of PC DNA, We performed PCR as a pilot study. Methods: PCP was induced on Spraque-Dawley rats with prednisolone 5mg IM twice a week. Bronchial lavages, impression smears, and permanent sections were performed from the 3rd week to 7th week of cortisonized rats. PC DNA was extracted with bead beater / 10% CTAB method. Results: Impression smears showed PC cyst after the 4th week (100%, 28/28 rats), and permanent sections showed 27/28 rats. Control rats showed some PC cysts (2/7). PCR result was positive only one case among the 6th week rats (1/7), But positive 6 cases at the 7th week rats, (6/7). Among control rats. 2 cases were positive (2/7). ??This data is a pilot study for the PC DNA detection using a PCR. PCP were successfully cortisonized rats. If adequate bronchial washing technique will be used, PCR can be a sensitive for PC DNA detection.

        김영인,고창옥,이채규,양승현 조선대학교 국토개발연구소 1994 국토개발연구 Vol.14 No.2

        Blast furnace, by-product of iron industry has widely used as reclamation materials for pavement or harbour construction. The studies which make blast furnace slag use as aggregates for concrete have being actived owing to natural aggregates insufficiency. In order to use air cooled blast furnace slag as a coarse aggregate for concrete which was fixed to 440kg, 400kg, 360kg, 320kg, 280kg, 240kg of cement content were performed. This study is aimed to ascertain the feasibility of utilizing the concreate with crushed slag aggregates and to find specific properties such as slump air content, compresive strength, tensile strength, bending strength. The results of this study are summarised as follows; 1. On the base of 320kg of unit cement weight the strength according to each dry day are similar in the condition of 45% of w/c whereas in the condition of 50% of w/c the strength of 7-days are similar, but the strength of 28-days are different. 2. In the relation of δ25 - c/w, the strength of slag concrete is greater than that of crushed storn concrete in condition of epual c/w except 400kg/㎥. 3. Slag of concrete as aggregate is destoryed with mortar. 4. The relation of δ28 and tensile strength is very good(γ = 0.8), the equation of regression analysis is δt= 0.63+0.00598 × 28. 5. The reation of bend strength and w/c is liner(γ = 0.72) the equation of regression analysis is δb=80-0.69w/c. 6. It must be care to abtain equal workability to natual aggregate concrete because the change of water absorption is greate. The water content of slag concrete is more than that of crushed storn concrete to obtain the same workability. It must be careful to use blast furnace slag as a coarse aggregate for concrete. And after investgating the quality of demended concrete carefully, real mixing work must be done.
