As the tendency of the society is centralized into consumers and services, patients are getting to ask better medical services. The consumers influenced from various social surroundings became to have some expectation of nursing service. Compared with their expectation, the quality of the services which they virtually get may be recognized and evaluated. So it is necessary to know exactly what the consumers want in nursing services. The purpose of this study is to examine the determinants which can evaluate the quality of nursing services by researching into consumers' expectation and perception of the nursing services depending on the consumer-oriented attributions on the basis of the model of SERVQUAL. 1,144 of outpatients were selected as the subjects for this research. They used to continuously visit the same hospital after being hospitalized and nursed in 9 hospitals randomly selected among the second-level medical organizations in Seoul from January to February, 2001. The collected data are analyzed into the Descriptive Statistics, t-test, GLM and Multiple Regression through the SAS program. Delphi was used for the research tool and the results of the research are as follows; the determinants in evaluating the quality of nursing services consist of 5 categories such as Tangibility, Reliability, Responsiveness, Assurance, Empathy. The values of Cronbach' $\alpha$ appeared to be 0.96 in the expectation of nursing services, 0.94 in the perception of nursing services and 0.96 in the importance of nursing services. The determinants in the expectation of nursing services were ranged in the order of Assurance, Empathy, Reliability, Responsiveness and Tangibility. And those in the perception of nursing services were in the order of Assurance, Empathy, Reliability, Tangibility and Responsiveness. Those in the importance of nursing service were in the order of Empathy, Assurance, Reliability, Tangibility and Responsiveness. Finally, those in the quality of nursing service were in the order of Tangibility, Responsiveness, Empathy, Reliability and Assurance. Each expectation of nursing services appeared different depending on the subjects' age, gender, clinical department and reason for hospitalization. The hypothesis examined in this research shows that the group having higher personal needs shows meaningful differences in the expectation of nursing services, and the subjects who have had external communication show higher perception of nursing service than uncommunicative ones. After all, we can see that the statistical differences in the perception of nursing services depend on whether the subjects have external communications or not. The determinants in the expectation of nursing services can explain the quality of nursing service up to 14.96%. The statistically meaningful determinants in the expectation could be arranged in the order of Reliability, Assurance and Tangibility. And the more expectation brings about the lower evaluation of the quality of nursing services. The determinants in the perception of nursing service can explain the quality of nursing services up to 29.85%. The statistically meaningful determinants in the perception could be arranged in the order of Responsiveness, Reliability, Tangibility, Empathy, and Assurance. And the more perception brings about the higher evaluation of the quality of nursing services. According to the result of the above research, I would like to propose as follows. As long as this research is oriented to get knowledge of the consumer-oriented nursing services, it should be continued to draw the other elements determining the quality of the nursing services. Furthermore, this research is based upon the Parasuraman, A., et al.'s SERVQUAL Model(1991), which deals only expectation, perception and quality of consumer-oriented nursing services, so it will be necessary to inspect and verify it through the other models containing the offerers of nursing services in the future. On the other hand, as this research evaluates the actual quality of nursing services based on the expectation and perception of nursing services, it can be utilized as fundamental data to develop the marketing strategies and to estimate the qualities as well. I hope this research will be periodically estimated to be the useful data to develop the marketing strategies in the nursing service area.

The nature of distant faint blue field galaxies remains a mystery, despite the fact that much attention has been devoted to this subject in the last decade. Galaxy counts, particularly those in the optical and near ultraviolet bandpasses, have been demonstrated to be well in excess of those expected in the 'no-evolution' scenario. This has usually been taken to imply that galaxies were brighter in the past, presumably due to a higher rate of star formation. More recently, redshift surveys of galaxies as faint as B$\~$24 have shown that the mean redshift of faint blue galaxies is lower than that predicted by standard evolutionary models (de-signed to fit the galaxy counts). The galaxy number count data and redshift data suggest that evolutionary effects are most prominent at the faint end of the galaxy luminosity function. While these data constrain the form of evolution of the overall luminosity function, they do not constrain evolution in individual galaxies. We are carrying out a series of observations as part of a long-term program aimed at a better understanding of the nature and amount of luminosity evolution in individual galaxies. Our study uses the luminosity-linewidth relation (Tully-Fisher relation) for disk galaxies as a tool to study luminosity evolution. Several studies of a related nature are being carried out by other groups. A specific experiment to test a 'no-evolution' hypothesis is presented here. We have used the AUTOFIB multifibre spectro-graph on the 4-metre Anglo-Australian Telescope (AAT) and the Rutgers Fabry-Perot imager on the Cerro Tolalo lnteramerican Observatory (CTIO) 4-metre tele-scope to measure the internal kinematics of a representative sample of faint blue field galaxies in the red-shift range z = 0.15-0.4. The emission line profiles of [OII] and [OIII] in a typical sample galaxy are significantly broader than the instrumental resolution (100-120 km $s^{-l}$), and it is possible to make a reliable de-termination of the linewidth. Detailed and realistic simulations based on the properties of nearby, low-luminosity spirals are used to convert the measured linewidth into an estimate of the characteristic rotation speed, making statistical corrections for the effects of inclination, non-uniform distribution of ionized gas, rotation curve shape, finite fibre aperture, etc.. The (corrected) mean characteristic rotation speed for our distant galaxy sample is compared to the mean rotation speed of local galaxies of comparable blue luminosity and colour. The typical galaxy in our distant sample has a B-band luminosity of about 0.25 L$\ast$ and a colour that corresponds to the Sb-Sd/Im range of Hub-ble types. Details of the AUTOFIB fibre spectroscopic study are described by Rix et al. (1996). Follow-up deep near infrared imaging with the 10-metre Keck tele-scope+ NIRC combination and high angular resolution imaging with the Hubble Space Telescope's WFPC2 are being used to determine the structural and orientation parameters of galaxies on an individual basis. This information is being combined with the spatially resolved CTIO Fabry-Perot data to study the internal kinematics of distant galaxies (Ing et al. 1996). The two main questions addressed by these (preliminary studies) are: 1. Do galaxies of a given luminosity and colour have the same characteristic rotation speed in the distant and local Universe? The distant galaxies in our AUTOFIB sample have a mean characteristic rotation speed of $\~$70 km $s^{-l}$ after correction for measurement bias (Fig. 1); this is inconsistent with the characteristic rotation speed of local galaxies of comparable photometric proper-ties (105 km $s^{-l}$) at the > $99\%$ significance level (Fig. 2). A straightforward explanation for this discrepancy is that faint blue galaxies were about 1-1.5 mag brighter (in the B band) at z $\~$ 0.25 than their present-day counterparts. 2. What is the nature of the internal kinematics of faint field galaxies? The linewidths of these faint galaxies appear to be dominated by the global disk rotation. The larger galaxies in our sample are about 2"-.5" in diameter so one can get direct insight into the nature of their internal velocity field from the $\~$ I" seeing CTIO Fabry-Perot data. A montage of Fabry-Perot data is shown in Fig. 3. The linewidths are too large (by. $5\sigma$) to be caused by turbulence in giant HII regions.

The purpose of this study was to develope and test the structural model for quality of life in women having hysterectomies. A hypothetical model was constructed on the basis of previous studies and a review of literature. The conceptual framework was built around eight constructs. Exogenous variables included in this model were marital intimacy, importance of uterus, professional support, positive coping behavior and pre-operative symptoms. Endogenous variables were spouse's support, sense of loss and quality of life. Empirical data for testing the hypothetical model was collected using a self-report questionnare from 203 women having hysterectomies at the outpatient clinics of four general hospitals and a mail survey in Pusan City. The Data was collected from December, 1997 to January, 1998. Reliability of the eight instruments was tested with Cronbach's alpha which ranged from 0.639-0.915. For the data analysis, SPSS 7.5 WIN Program and LISREL 8.12 WIN Program were used for descriptive statistics and covariance structural analysis. The results of covariance structure analysis were as follows : 1. Hypothetical model showed a good fit with the empirical data. ［$\chi$$^2$＝6.93(df＝5, P＝.23), GFI＝.99, AGFI＝.94, RMSR＝.019, NNFI＝.97, NFI＝.98, CN＝440, standardized residuals(-2.14-2.10)］ 2. For the parsimony of model, a modified model was constructed by deleting 3 paths and adding 1 path according to the criteria of statistical significance and meaning. 3. The modified model also showed a good fit with the data. ［$\chi$$^2$＝5.26(df＝7, P＝.63), GFI＝.99, AGFI＝.97, RMSR＝.014, NNFI＝1.02, NFI＝.99, CN＝710, standardized residuals(-1.46-1.70)］ Results of the testing of the hypothesis were as follows : 1. Marital intimacy(${\gamma}$11＝.78, t＝14.37) and professional support(${\gamma}$13＝.12, t＝2.12) had a significant direct effect on the spouse's support. 2. Pre-operative symptoms(${\gamma}$25＝.32, t＝3.12), importance of uterus(${\gamma}$22＝.20, t＝2.61) and spouse's support($\beta$2l＝-.19, t＝-2.43) had a significant direct effect on the sense of loss. 3. Sense of loss($\beta$32＝-.66, t＝-9.83) had a direct effect on the quality of life. Marital intimacy had a direct(${\gamma}$31＝.19, t＝3.33), indirect(${\gamma}$31＝.14, t＝2.52) and total effect(${\gamma}$31＝.25, t＝4.41) on the quality of life. Professional support had a direct effect(${\gamma}$33＝.11, t＝2.07) and total effect(${\gamma}$33＝.13, t＝2.31) on the quality of life. The direct effect of pre-operative symptoms(${\gamma}$35＝-.36, t＝4.02) and positive coping behavior(${\gamma}$34＝.15, t＝2.06) had the insignificant effect on the quality of life while, due to the idirect effect these variables had overall significant effect on the quality of life. The results of this study showed that the sense of loss had the most significant direct effect on the quality of life. Marital intimacy, pre -operative symptoms and spouse's support had a significant direct effect on this sense of loss. These four variables, the sense of loss, marital intimacy, pre-operative symptoms and spouse's support, were identified as relatively important variables. The results of this study suggested that there is needed to determine if nursing intervention would alleviate this sense of loss and promote a greater quality of life in women who have had hysterectomies.

목적: 방사선치료와 항암제치료의 급성부작용은 환자 개인에 따라 차이가 많다는 것은 임상경험을 통하여 널리 알려져 있다. 그러나 아직 이를 미리 예측할 수 있는 인자로 알려진 것은 없다. XRCC1 유전자는 DNA base-excision repair에 관여하는 유전자로 알려져 있다 저자들은 대장 직장암 환자를 대상으로 방사선치료와 항암제치료로 인한 급성부작용과 XRCC1 유전자의 다형성이 관련이 있는지를 알아보고자 본 연구를 수행하게 되었다. 대상 및 방법: 1997년 7월부터 2003년 6월까지 인하대학교병원에서 치료를 받은 대장 직장암 환자 85명을 대상으로 하였다. 대장암이 2명, 5자결장암이 13명, 직장암이 71명이었다 병기는 B기가 22명, C기가 50명, D기가 8명이었고 절제 불가능한 경우가 6명이었다 방사선치료 범위는 골반강만 조사된 경우가 81명, extended field로 조사된 경우가 5명이었고 방사선량은 일일 1.8 Gy로 주 5회 조사하여 총 $30.6 Gy{\sim}59.4 Gy$ (중앙값: 54 Gy)를 조사하였다. 항암제치료는 전 환자에서 5FU를 근간으로 한 약제를 투여받았고 방사선 치료기간 중에 시행된 횟수는 1회가 24명, 2회가 45명이었고 17명은 동시에 투여 받지는 않았다. 치료의 급성부작용은 상부위장관과 하부위장관으로 나누어 기록하였고 증상이 전혀 없는 경우를 0, 증상이 있으나 투약이 필요하지 않은 경우를 1, 투약이 필요한 경우를 2, 투약에도 불구하고 증상이 심하여 치료의 휴식 또는 입원을 한 경우를 3으로 분류하였고 전 치료기간 중 최초, 최저 수치와 방사선치료기간 중 최초, 최저 백혈구, 혈소판 수치를 조사하였다. 환자의 동의 하에 혈액을 채취하여 림프구를 분리한 후 DNA를 추출하여 PCR-RFLP 방법으로 XRCC1 유전자의 코돈 194, 280, 399번 위치의 다형성을 분석하였다. 통계는 Chi-square, t-test, logistic regression, ANOVA를 사용하였다. 결과: 다변량 분석결과 상부위장관 부작용에 영향을 미치는 인자는 재발유무였고, 하부위장관의 부작용에 영향을 미치는 인자는 XRCC1 339 다형성, 방사선량, 방사선 중 항암제횟수 순이었다. 방사선 치료 중 백혈구 감소에 영향을 미치는 인자는 XRCC1 399 다형성, 194 다형성이었고, 혈소판 감소에 영향을 미치는 인자는 진단명, XRCC1 399 다형성이었다. 결론: 대장 직장암 환자에서 방사선치료와 항암제의 치료에 따른 정상조직의 급성부작용을 예측하는데 XRCC1 유전자의 코돈 399번의 다형성이 사용될 가능성이 있을 것으로 생각된다.

This is preliminary report on anthrax epidemic occurred in an island with about 100 residents. Since 1982 there had been sudden deaths among all kinds of domestic animals including cattle, dogs, ducks, chicken and goat but only a few among cats in an isolated island about three hours distance away by ferry boat from Mokpo city. From 1986 through 1988 nine human deaths and four patients occurred, which made the government intervene for investigation on June 25 1988. The epidemiological investigation consisted of interview survey and medical examination, medical record analysis, laboratory work to isolate the pathogens under the direction of hypothesis derived from the study and further confirmation of the pathogens by international institute. The summarized results are as followings: 1. According to the interview survey there were many deaths among domestic animals usually in cold and dry season such as January through March and September through November; 36 heads of cattle leaving one head, more than 40 hogs(all), hundreds of chicken leaving few alive, goats that had taken home from mountain and two or three cats out of around 40 had sudden deaths from 1982 till 1985, when the residents stopped to purchase and take them into the island anymore. Also there were eleven persons who had experienced the similar syndrome complex to those of admitted and expired patients and four of them revealed typical chest X-ray findings; from one of these four patients(Rho) B. anthracis is isolated. 2. Medical record on patients who had been admitted, showed common characteristics of the disease course. On admission they had either gastrointestinal or upper respiratory infection symptoms which invariably progressed to septicemic nature with pulmonary interstitial infiltration and mediastinal widening/bulging, and then to deadly acute respiratory distress syndrome. At the end stage chest X-ray revealed multiple bullous emphysema. One of another characteristics was oral ulceration with bleeding occurred in about 50% of the patients. Laboratory test results in common were leukocytosis with left shift and abnormal liver and kidney functions, particularly at the later stage of the illness. 3. Epidemiological characteristics was striking in that both mortality and incidence rates were high: the mortality rate was 8.7% average, male being three times higher than females but there was no distictive clustering by age group. The incidence rate for both sexes was 28.2% and there was no sex difference although a tendency of higher incidence among older ages was noticed. The highest mortality and incidence were observed in Won village where the first death of animal occurred and with the highest frequency among three villages of the island. 4. Among twelve bacilli species isolated from various specimens, two strains, one from patient and the other from soil where the recently died cow is hurried, were confirmed as B. anthracis by Pasteur Institute and CDC of USA(strain from soil). CDC reported that the strain did not produce capsule in bicarbonate media but reacted with the bacteriophage and one of five sera taken from the patients. Mode of transmission as well as incubation period of the agent has not been established yet, which needs further investigation in relation to the antigenic structure of the variant when it is confirmed.

The purpose of this study was to develope and test the structural model for depression in middle-aged women. A hypothetical model was constructed on the basis of previous studies and a review of literatures. The conceptual framework was built around eight constructs. Exogenous variables included in this model were volunteer activity, health status & economic status. Endogenous variables were meaning of life, self-esteem, perceived life stress & depression. Empirical data for testing the hypothetical model was collected using a self-report questionnaire from 216 middle-aged women in Pusan City. The Data was collected from May to June, 1999. Reliability of the seven instruments tested with Cronbach's alpha was ranged from .86-.94. For the data analysis, SPSS 7.5 WIN Program and LISREL 8.12 WIN Program were used for descriptive statistics and covariance structural analysis. The results of covariance structure analysis were as follows: 1. The hypothetical model showed a good fit with the empirical data. [$x^2$/df=2.87(p=.72), GFI=1.00, AGFI=.98, RMSR=.025, NFI=.99, standardized residuals ($-1.44{\sim}1.44$)]. 2. To heighten for the parsimony and fitness of the model, a modified model was constructed by deleting according to the criteria of statistical significance and meaning. 3. The modified model also showed a good fit with the data. [$x^2$=5.26(01=7,p=.63), GFI=.99, AGFl=.97, RMSR=.025, NFI=.99, standardized reslduals ($-1.50{\sim}1.45$)] Results of the testing of the hypothesis were as follows : 1. Self-esteem(${\beta}_{42}$=-.48, t=-5.64) had a negative and perceived life stress(${\beta}_{43}$=.20, t=3.21)had a positive direct effect on depression. Meaning of life had a negative direct(${\beta}_{41}$=-.17, t=-2.19) and a negative indirect effect through self-esteem on depression. Volunteer activity had a negative indirect effect through meaning of life, meaning of life and self-esteem on depression. Health status had a negative direct and a negative indirect effect through meaning of life, meaning of life and self-esteem on depression. Economic status had a negative indirect effect through perceived life stress on depression. Self-esteem was the most significant variable. 2. Volunteer activity(${\gamma}_{11}$=.43, t=6.78) and health status(${\gamma}_{12}$=.35, t=4.88) had positive direct effect on meaning of life. 3. Meaning of life(${\beta}_{21}$=.50, t=6.53) had a positive direct effect on self-esteem. Volunteer activity had a positive indirect effect through meaning of life on self-esteem. Health status had a positive direct(${\gamma}_{22}$=.18, t=2.23) and a indirect effect through meaning of life on self-esteem. Meaning of life was the most significant variable. 4. Economic status (${\gamma}_{33}$=-.44, t값=-6.01) had a positive direct effect on perceived life stress. The results of this study showed that self-esteem had the most significant direct effect on depression. Meaning of life and health status had significant direct effect on this self-esteem. Volunteer activity and health status had direct effect on meaning of life. The results of this study suggested that there is a need to develope intervention to promote degree of self-esteem and alleviate degree of depression in middle-aged women.

The purpose of this study was to determine the effectiveness of instructors' utilization of the reserve collection in the university library. To accomplish this, an experiment-and-questionnaire study was done by selecting an experimental group for whom the teaching method utilizing the reserve collection was used and a control group for whom the method was not used. An experimental group and a control group studied were as follows: (1) Students take the 'Comparative Politics' course in the Department of Political Science. (2) Students take the 'History of 'English Literature' course III the Department of English Language and Literature. The data to test the hypothesis were analyzed by SPSS/PC+ routine. The results are as follows: (1) There were significant differences between the experimental group and the control group in academic achievement(T(228)=6.69, P<.01). To investigate the difference in effect by major, the one-way analysis of variance was employed. According to the results, there were significant differences between the experimental group and the control group In the Department of Political Science and the Department of English Language & Literature. Therefore, students for whom the teaching method utilizing the reserve collection was used have higher academic achievement than those for whom the method was not used. (2) As for the degree of utilizing the library and its materials, there were significant differences between the experimental group and the control group(T(228)=8.87, P<.01). As for the results of the one-way analysis of variance to investigate the difference in effect by major, there were significant differences between the experimental group and the control group in both departments. As for the degree of utilizing library catalogues and bibliographical tools, there were significant differences between the experimental group and the control group(T (228)=8.55, P<.01). As stated earlier, the one-way analysis of variance to investigate the difference in effect by major has shown that there were significant differences between the experimental group and the control group in both departments. As for the degree of sincerity in doing homework and writing papers, there were significant differences between the experimental group and the control group(T(176)=8. 03, P<.01). To investigate the difference in effect by major, the one-way analysis of variance was again employed. According to the results, there were again significant differences between the experimental group and the control group in both departments. So, the students for whom the teaching method utilizing the reserve collection was employed used library catalogues and bibliographical tools much more than those for whom the method was not employed, and were more sincere in doing homework and writing papers. (3) There were also significant differences between the experimental group and the control group in degree of satisfaction in taking the course (T (228) = 6.61, P<.01). The results of the one-way analysis of variance to investigate the difference in effect by major was that there were significant differences between the experimental group and the control group in both departments. Therefore, the degree of satisfaction of students who were taught by the teaching method utilizing the reserve collection is higher than that of those who were not taught by the method. On the other hand, the responses of the experimental groups of two departments as to the degree of satisfaction with their teaching method was investigated. The result shows that students who took the 'Comparative Politics' course in a small class which employed the seminar method were higher in degree of satisfaction with the teaching method than students who took the 'History of English Literature' course III a large class which employed a lecture-oriented teaching method.

본 연구에서는 국내 패밀리 레스토랑 업체를 대상으로 변혁적 리더십과 서비스리더십에 대한 선호도를 조사하고, 서비스 리더십의 수준에 따른 종업원의 만족도를 살펴보고 효과적인 리더십의 유형을 모색하고자 하였다. 본 연구 결과에 의하면 리더십의 선호도에 있어서는 변혁적 리더십의 선호도$(25\%)$보다 서비스리더십에 대한 선호도$(75\%)$가 높은 것으로 나타났다. 가설 2의 검증에 있어서 서비스 리더십 수준이 높은 집단의 종업원 만족도가 서비스 리더십 수준이 낮은 집단의 종업원 만족도보다 높을 것이라는 가설이 채택되었다. 이는 직무만족의 3가지 구성요소에 있어서, 그리고 종합적인 만족점수에 있어서도 유의적(p<0.001)인 차이를 나타내 서비스리더십의 수준이 높은 집단이 낮은 집단보다 직무만족이 높음을 알 수 있었다. 또한 서비스리더십의 구성 요소인 서비스 신념, 태도, 능력, 통찰력이 종업원의 만족도에 양의 상관관계가 있을 것이라는 가설이 지지되었다. 또한 서비스리더십의 선호집단과 변혁적 리더십의 선호집단에 있어서 종업원의 만족도가 차이가 있을 것이라는 가설은 채택되지 않았는데, 이는 리더십의 선호도에 있어서 $75\%$의 패밀리 레스토랑의 종사원이 서비스 리더십을 선호한다고 응답하여 높게 나타났고, 선호하는 리더십과 실제로 수행되고 있는 리더십에 있어서는 차이가 있기 때문일 것이라고 추정된다. 본 연구는 현재 서비스 기업의 엄청난 부가가치의 생산과 더불어 그 중요성이 부각되고 있는데, 무형적인 가치의 제공과 고객과의 접점에서 즉각적으로 제공되는 서비스의 특성을 고려한 서비스리더십에 대한 이론을 고찰하고, 이것이 패밀리레스토랑에 적용가능성 타진해 봄으로써 효과적인 리더십을 돌출했다는 것에 의의를 둘 수 있다. 그러나 서비스리더십의 이론에 대한 심층적인 연구가 부족하고, 실제로 검증해본 연구들이 양적으로 적어서 일반화의 과정에 있어서는 아직 한계를 가지고 있다. 따라서 앞으로의 후속 연구에 있어서 이론의 논리적 구성에 대한 검증과 외식업체에서 다양한 직무를 수행하고 있는 종사원을 대상으로 적용해보는 실증 연구가 필요할 것으로 사료된다.

본 연구는 광중합형 상아질 접착제에서 광조사 시간의 증가가 접착제 표면의 미중합층에 대한 영향과 그에 따른 전단접착강도에 대해 연구하고자 120개의 치아를 아크릴 몰드에 식립한 후 상아질이 노출되도록 연마하였다. 3종류의 접착제 〔All Bond2 (AB2), One-Step (OS) and Adper Prompt (AP)〕를 40개 치아에 제조사의 지시대로 도포한 후 각각 다른 광조사 시간 (10, 20, 30 and 60sec)동안 광조사 하고 복합레진을 접착한 24시간 후 전단접 착강도를 측정하였다. 미중합층의 두께와 중합률은 슬라이드 글라스와 FT-NIR을 이용하여 FT-NIR spectrum에서의 peak height를 비교 측정하여 다음과 같은 결론을 얻었다. 1. 전단접착강도에서 AB2는 20초 이후 감소하고, AP는 30초까지 증가하였으며,OS는 차이를 보이지 않았다. 2. 미중합층 두께는 3가지 접착제 모두 유의성 있는 차이를 보이지 않았다. 3. 중합률에서 OS는 10초와 나머지군 사이에 유의성 있는 차이를, AP는 60초에서 유의성 있게 증가되고, AB2의 경우 차이를 나타내지 않았다.
