Purpose - Environmental issues, climatic changes, and greenhouse gases are problems to be solved at a global level. With an increased emphasis on the environmental and social responsibility of the management of companies, the manner in which companies approach quality-oriented culture and their individual sustainability management are being discussed as truly important issues to help them secure their competitiveness and growth strategies. This study proposes strategic directions to help manufacturers not only in expanding their competitive quality-oriented company culture but also in strengthening their sustainability management abilities. This study conducts a literature review and empirical research to examine how significantly the variables of a quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. Research design, data, and methodology - To verify research models and hypotheses, the study examined 170 companies using a questionnaire survey conducted over six weeks, and involved the performance of data analysis on 146 samples. Questionnaire responses were calibrated based on a Likert scale. The study used the Smart PLS 2.0 program designed for PLS (partial least squares), an analysis instrument of SEM (structural equation modeling). The study then verified empirical research hypotheses working on reliability analysis, validity analysis, factorial analysis, and path analysis. Results - Among the nine hypotheses, four are accepted and the rest are rejected. A quality-oriented company culture focusing on customer-centered management significantly influenced the maintainability management performance of environmental integrity and social responsibility, while economic profitability was dismissed. A process-focused quality-oriented company culture was significantly concerned with economic profitability but not with environmental integrity or social responsibility. A supply-chain cooperative company culture had a significant effect on economic profitability but not on environmental integrity or social responsibility. Conclusion - This study proposes strategic directions to help manufacturers expand their competitive quality-oriented company culture as well as strengthen abilities with sustainability management. It conducts a literature review and empirical research to examine how significantly the variables of quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. There are two main conclusions. First, companies should consider the need for social responsibility management and environmental transparent management-focused maintainability management as avenues to create new markets and business, thereby helping the companies secure a reputation for having a customer and process-centered quality-oriented company culture by creating shared values between supply chains and enabling win-win situations through cooperation. Second, we are marching towards a creative win-win era from a society of conflicts and ruptures. Companies should understand that social responsibility management and supply chain management (SCM)-focused cooperation are the foundations of sustainable development, as they try to improve their culture while pursuing both win-win relationships with interested parties and equity in various conflictive relations.

Based on King's goal attainment theory, this research deals with applying nursing intervention of mutual goal settings to gastrectomy patients. It tests the effects of nursing intervention, according to the patients' health locus of control, suggested as external boundary criteria for the theory by employing a quasi-experimental design which consists of a pretest-posttest non-equivalent control and experimental groups. The subjects of this research were 62 gastrectomy patients hospitalized at Y medical center and the experimental and control groups consisted of 31 subjects. The experimental group received nursing intervention at the mutual goal setting of 5 times from the day before the surgery to the 5th day after the surgery, while the control group received only routine nursing care. Recovery indicators of both groups were measured and compared. Measurement variables included patients' characteristics, health locus of control, forced vital capacity, forced expiratory volume in one second, peak expiratory flow, bowel movement recovery, mobility recovery, level of pain, patients' stress and patients' satisfaction. Data were analyzed using SPSS statistical package and the hypotheses were tested by ANOVA and ANCOVA. Results of the analyses are summarized as follows : 1) Internal health locus of control had higher effects of the nursing intervention of mutual goal setting than external health locus of control on pulmonary ventilatory functions of forced vital capacity, forced expiratory volume in one second, and peak expiratory flow. 2) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the bowel movement recovery between the internal and external health locus of control. 3) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the mobility recovery between the internal and external health locus of control. 4) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of pain between the internal and external health locus of control. 5) There was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of stress between the internal and external health locus of control. 6) There was a statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of satisfaction with provision of nursing information between the internal and external health locus of control, and there was no statistically significant difference in the effects of nursing intervention of mutual goal setting on the level of satisfaction with outcome of nursing between the internal and external locus of control. On the basis of the research results, the following are recommended : 1) Repeated research on responses to health locus of control is necessary. 2) Not only the effectiveness of nursing intervention in acute recovery periods, but also the long term effects are to be investigated. 3) The development of instruments is needed to accurately measure mutual goal setting regarding postoperative deep breath, coughing, early ambulation, etc. so that the relationship among the postoperative recovery indicators may be explored. 4) It is required that an instrument be developed to measure perception which facilitates goal attainment in the interactive setting between patients and nurses.

Purpose: The purpose of this study was to help enhance the quality of life for women with urinary incontinence. Self-esteem, urinary symptoms, peak pressure and duration in seconds for vaginal contraction after pelvic muscles exercise were examined. Method: One-group pretest-posttest design was employed participants were 27 married women from G city. The instrument for this study were : the self-esteem scale developed by Rosenberg(1965). the Urinary Symptom Questionnaire, a subjective measurement of urinary incontinence, developed by Jackson et al.(1996) and the Perineometer used as an objective measurement of peak pressure and duration in seconds. Result: 1. Self-esteem showed significant improvement after the exercise (t=-3.832, p= .001). 2. Comparison of results before the pelvic muscles exercise and after showed that there was a statistically significant difference for several urinary symptoms including enuresis (t=2.833, p=.009), frequency of incontinence (t=2.964, p= .006), incontinence volume (t=2.280, p= .031), incontinence before getting to the restroom (t=3.035, p= .006), incontinence with no reason or feeling (t= 3.051, p= 005) burning sensation (t= 2.132, p=.043), and a sense of residual urine (t=2.267 p=.032). The mean scores showed improvement in the urinary symptoms of management of incontinence (M=$0.04{\pm}0.22$), daily frequency of incontinence management (M=$0.13{\pm}0.85$), urinary control (M=$0.15{\pm}0.86$), running to the restroom (M=$0.15{\pm}0.60$) incontinence caused by coughing or physical activities (M=$0.19{\pm}0.57$) and hesitancy (M=$0.07{\pm}0.55$). Overall urinary symptoms decreased significantly (t =3.073. p= .007). 3. Peak pressure showed an increase from a mean of $24.26{\pm}16.20mmHg$ before the exercise to a mean of $28.63{\pm} 17.79mmHg$ after (t=-2.399, p=.024). Duration in seconds also increased from a mean of $6.00{\pm}4.95sec$ to $9.15{\pm}5.83sec$ (t=-4.400, p= 000). Conclusion: These findings suggest that pelvic muscle exercise serves to decrease urinary problems, improve self-esteem and increase peak pressure and duration in seconds.

The purpose of this study was to find out women's need and level of knowledge about episiotomy, pain and discomfort related to episiotomy on a cross-sectional survey design. The subjects were 102 postpartal women agreed on oral consent. 34 postpartal women admitted at obstetric ward of H university hospital, 34 postpartal women admitted at 2 Sanhujoriwons, and 34 women within one year afterbirth. They were selected in Seoul, Korea. Data were collected from July, 1 to September 30, 2000, by a structured questionnaire. The instrument used for this study was a questionaire consisted of 5 items of general characteristics, 12 items of obstetric characteristics, 10 items of level of knowledge (Chronbach $\alpha$ .8176), 8 items of need of education(Chronbach $\alpha$ .8836), 3 items of pain (Chronbach $\alpha$ .9252), and 3 items of discomfort (Chronbach $\alpha$ .8092). The data were analyzed by the SPSS/PC+ program using t-test, ANOVA and Scheffe test as a post hoc and Pearson Correlation Coefficient. The results of the study were as follows; 1. 63.2% of respondents had right answer on 6-8 items among 10 items. Only 4.4% of women got right answer on 10 items all. 2. The need of education was high(4.45%) on all items and the range of score was $4.25{\sim}4.64$. 3. The strength of pain was the highest within one week afterbirth(5.93/10) and became lower in 8-14 days afterbirth(2.55). And after 15days of postpartum, the pain level became to the lowest level(1.08). However, pain was delayed until more than one month afterbirth. 4. The level of discomfort was the highest one week afterbirth(6.88/10) and became lower in 8-14 days afterbirth(4.20). And after 15days of postpartum, the discomfort level became to the lowest level(2.47). Universally, the degree of discomfort was higher than pain. 5. There was a strong positive correlation between discomforts and pain ($r=.752^{**}$) and weak positive correlation between discomforts and the level of educational need($r=.308^*$). In conclusion, women have a right to choose whether she will have episiotomy or not according to her decision making based on the comprehensive knowledge of episiotomy before they get episiotomy with consent process and explanation in detail. Women health care providers like nurses have a responsibility to do conscious raising and empowerment for women so that they could lead themselves to choose given medical treatments for women's health and wellbeing and the quality of life in her life cycle.

탄성파 탐사를 이용한 지질구조 규명에 있어 정확한 속도모델 구축이나 영상화 기술 개발만큼 중요한 것이 자료의 분해능을 높이는 기술이다. 일반적으로 자료취득 과정에서 고주파 송신원을 사용하거나 자료처리 과정에서 곱풀기(deconvolution) 등의 기법을 적용하여 분해능을 향상시킬 수 있다. 그러나 해양 탄성파 탐사에서 분해능을 저해하는 가장 큰 원인은 도깨비파에 의한 특정 주파수 성분의 손실이다. 따라서 도깨비파를 제거하면 주파수 손실을 방지하여 광대역 탄성파 자료를 얻을 수 있고, 결과적으로 높은 분해능의 지층 영상을 얻을 수 있다. 도깨비파 제거는 자료처리 과정에서 적절한 필터를 적용하여 수행할 수 있지만, 최근에는 탐사 장비의 발전과 탐사 설계의 혁신을 통해 효과적인 광대역 탄성파 탐사 기술이 개발되고 있다. 해외 탐사전문 기업들은 오버/언더 스트리머나 가변 심도 스트리머와 같이 새로운 수신기 배열을 개발하거나 이중 센서 스트리머를 이용한 도깨비파 제거 기술을 확보하여 고분해능 영상화 기술을 제공하고 있다. 안타깝게도 국내에서는 광대역 탄성파 탐사 장비나 기술에 대한 연구가 거의 이루어지지 않고 있다. 본 논문에서는 국내 광대역 탄성파 탐사 연구에 도움이 될 수 있도록 그 기본 이론과 기술 현황을 소개하였다.

본 논문은 철도차량의 출입문과 역사의 플랫홈 사이에서 승객의 승하차시에 발생할 수 있는 안전사고를 방지하기 위한 안전발판장치에 관한 것으로서, 특히 출입문의 개폐작동에 따라 연동하여 작동되는 안전발판을 구비하는 것에 의해 별도의 동력과 제어장치를 필요로 하지 않음은 물론, 오작동 없이 정확하게 동작되도록 한 철도차량의 안전발판장치에 관한 것이다. 일반적으로, 지하철 역사의 플랫홈과 철도차량 간에는 열차의 원활한 안전주행을 위해 일정한 간격(이하 "연단간격"이라 함)이 유지된다. 이러한 연단간격은 가능한 한 좁게 형성되도록 구축되는 것이 바람직하나 그러기 위해서는 역사를 직선으로 건설해야 하지만, 통상 지하철은 도심의 인구집중지역의 기존 대로를 따라 노선이 결정되어 공사가 이루어지므로 도시가스배관, 도로주변의 고층대형건물, 기존도로의 형상 및 지하수와 같은 여러 가지 조건에 의해 많은 역사들이 곡선부분을 포함하여 건설될 수밖에 없다. 이 때문에, 철도차량과 플랫홈 간의 연단간격이 크게 벌어지는 구간이 형성되어 짧은 정차시간에 많은 사람들이 승하차하면서 연단간격으로 승객의 발이 빠지는 등의 안전사고가 빈번히 발생하고 있다. 이와 같이, 연단간격이 커짐에 따른 사고발생을 줄이기 위하여 연단간격이 큰 부분에 경고등을 설치하거나 경보음을 발생시키는 방법을 사용하였다. 이러한 경보장치는 차량이 지정된 궤도로 진입하면, 경고등에서 빛을 발산하여 차량과 플랫홈 사이의 공간에 대한 위험성을 승객에게 주의시키면서 경보나 안내방송이 나오게 하고, 차량이 역사를 출발하여 궤도를 지나면 그 작동이 멈추는 장치이다. 그러나, 이러한 경보장치는 위험성을 승객에게 알려 승객 스스로가 위험에 대처하도록 하는 주의정보제공의 기능만을 가지는 장치로서, 바쁜 출퇴근 시간이나 혼잡한 상황에서는 만족할 만한 효과를 기대하기 어려웠고, 특히 위험 대처능력이 떨어지는 어린아이나 노약자에게는 위험성이 그대로 상존하는 문제점이 있었다. 이와 같은 문제점으로 인하여 경전철이 있는 나라에서는 경전철용 차량에 승객이 안전하게 승하차할 수 있도록 계단식 발판을 설치하는 차량용 발판이 제공되어 있으나, 국내 지하철에 적용하기에는 차체 및 역사의 구조상 불가능하였다. 차량의 바닥이 플랫홈과 거의 동일 레벨상에 위치하므로 안전발판이 차량의 바닥과 수평이 되도록 작동되어야 하고, 차량에 있어서도 스테인레스 차량인 경우 사이드 빔(Side beam), 알루미늄 차량인 경우 솔바(Sole bar)에 구멍을 뚫으면 전체적인 차체의 강도 및 구조상의 문제가 발생되기 때문이다. 본 논문에서 이전에 개발된 국내외 안전발판장치를 소개하고 연단간격과, 차량 플랫홈의 높이의 차이에서 발생하는 문제를 함께 해결하는 안전발판장치를 해결책으로 제시하고자 한다.
