  • Because of the changing educational environments, Korean universities have to stand up to the challenge of enhancing their performances in educational activities. Therefore, Korean universities should seek ways to improve its competitiveness. The evaluation of Korean universities has been conducted by the Government and other media agencies like JoongAng's Daily to promote the development of universities. The purpose of this study is to evaluate and compare the relative efficiency of Korean universities using DEA (Data Envelopment Analysis) and AHP (Analytic Hierarchy Process) models. To produce reasonable results, major input and output variables have been determined in a step using a Profiling method, Spearman correlation analysis and AHP model. Also, this study shows that the relative efficiency for Korean universities is obtained not only based on quantity of output, but also on the basis of the quality of the output. Drawing upon the results of the analysis, this study provides a comprehensive and practical method for evaluating the performance of universities in terms of efficiency.

  • Purpose: To evaluate the relationship between organizational socialization and intention to leave, and to identify factors affecting on intention to leave in operating room nurses. Methods: This study used a descriptive design. Seventy operating room nurses recruited from three hospitals under the same management style, in-service educational system, and working conditions agreed to participate in this study, and completed self-administered questionnaires of the organizational socialization and the intention to leave questionnaire. Respondents were classified by career as advanced beginner, competent practitioner, proficient practitioner and expert practitioner by Benner's stages of nursing proficiency. Data were analyzed with t-test, ANOVA with multiple comparisons, Spearman correlation, and multiple regression analysis. Results: Nurses unsatisfied with the current in-service continuous education had lower organizational socialization and higher intention to leave. In advanced beginners, job performance was lowest and organizational commitment was highest. In expert practitioners, intention to leave was highest. Organizational commitment, interpersonal relationship, identity and burnout were associated with intention to leave. Mutual trust, burnout, and interpersonal relationship were predictors of intention to leave explained 20.8% of variance. Conclusion: The career ladder program to enhance nurses' organizational socialization and intention to stay should be established and expanded for well-experienced operating room nurses.

  • Background and Objectives : While considerable progress has been made in enhancing the quality of laryngoscopy and image processing, the evaluation of laryngeal erythema is still based on the clinician's judgement. The purpose of this study is to quantitatively measure the degree of erythema and to examine the relationship with clinical grading. Materials and Methods : Color images of larynx from 100 subjects were captured from video-documented examinations of laryngoscopy. The amount of erythema within the digitized larynx image was quantified using software developed and was compared with a grading system (0 to 3 scale) based on visual inspection by 4 experienced clinicians. The results were compared by deriving Kappa, Kendall and Spearman statistic. Results : There was high intra-observer(R=0.402-0.755) and inter-observer correlation (R=0.789). Among parameters, the red composite value had most remarkable agreement with clinical grading(R=0.827). Conclusion : The result suggest that the computer based analysis of laryngeal erythema can provide quantiative data on degree of erythema and the basis for further development of an expert system.

  • Purpose: This study was aimed to identify the incidence and severity of chemotherapy-induced peripheral neuropathy (CIPN) among patients with hematologic malignancies and to examine the relationship between the quality of life (QOL) and CIPN. Methods: A total of 66 patients with CIPN-related symptoms participated in this study. Data were collected through self-reported questionnaires consisted of the European Organization for Research and Treatment of Cancer QLQ-C30 version 3.0 and the 16-item QLQ-CIPN20. Data were analyzed with SPSS/WIN20 for descriptive statistics using the Mann-Whitney and Kruskal-Wallis tests, and Spearman's rho. Results: The mean lower and upper extremity scale scores were 31.95 and 23.16 respectively for the 16-item QLQ-CIPN20. The mean QLQ-C30 subcategory scores were 46.84 for global health status, 58.72 for functional scales, and 34.85 for symptom scales. The CIPN-related lower extremity scale symptoms correlated negatively with the QOL subscales. There was no correlation between CIPN-related upper extremity symptoms and health-related QOL. Conclusion: Patients with hematologic malignancies treated with neurotoxic chemotherapeutic agents had CIPN-related symptoms in the lower extremities mainly, and their QOL functional subscale scores were relatively lower than those of other cancer patients. Interventions need to be developed for patients with hematologic malignancies to alleviate CIPN and enhance their QOL.

  • Lineament maps are the important tools that may reveal points of groundwater recharge, flow and development. In particular, groundwater flows and yields in mountainous area, composed of crystalline rocks with many fractures, are governed mainly by the lineaments corresponding to fractures, joints and faults. Lineaments may give important information on the best distribution of wells and their management. For two districts; Pohang and Cheonan, the relationship between lineament and groundwater factors was analyzed. To compare groundwater productivity, storativity, and transmissivity of a well site along the distance to lineament, the distances to lineament was regrouped into five groups with an equal range, 100m, for the Pohang district and they are also divided into five groups with an equal range, 150m, for the Cheonan district. From the results of the Spearman Rank Correlation Analysis and Kendall Analysis for each group, the means of SPC and T of wells which are located near lineaments generally have large values. The means of SPC and T show a reverse linear relationship with a lineament distance, but the means of S shows a disperse distribution and no distinct linear relation. Result of the linear regression model between SPC and lineament length density shows that it will be effective to use the lineament length density map when finding the optimal well site on a regional scale.

  • In this paper, we surveyed the actual utilization condition of chain stores of franchise systems and the customers' consciousness on chain shops and non-chain restaurants. The survey was conducted on 459 people either living or working in Pusan area and aged more than 4th grade in elementary school without sex distinction. The data analyses were made by way of frequency, percentage, Spearman rank correlation and Chi-square using dBastat 1.0 package of PC. The results of the survey are as follows. The survey indicates that respondents have the most experience of visiting chicken, hamburger, and pizza chain shops. Although the survey on the degree of preference between chain shops and non-chain restaurants indicates that men prefer non-chain restaurants and women prefer chain shops, the results are not so significant to conclude that there is a preference regardless of sex (N. S.): By ages, students and young group prefer chain shops and the aged group prefer non-chain restaurants (p< 0.05). The survey indicates that chain shops are proffered because of sanitary, quality, taste of foods and are not proffered because of simple menu and expensiveness. The survey indicates that non-chain restaurants are preferred because of distinctive taste of each restaurant and comfotableness, and are not proffered because of unsanitary and unkindness.

  • The purpose of this study was to identify the factors of university residence hall foodservice quality which has correlations with subjective QOL (quality of life) of target customers. A total of 176 questionnaires from students of 4 universities in Daegu, Gyeongbuk area were used for the analysis. The male students using residence hall foodservices were highly satisfied with 'clean appearances of employees' ($4.86{\pm}1.25$) and 'clean facilities' ($4.79{\pm}1.26$), while the degree of satisfaction with 'convenient facilities' ($4.50{\pm}1.20$) showed the highest score with female students. Ranking analysis using Spearman's ${\rho}$ revealed that there were significant correlations between students' satisfactions with the dimensions of 'foods and kindness of employees', 'hygiene', 'nutrition', and 'convenience' and their QOL, even though physical QOL of female students showed no significant correlation with satisfaction towards residence hall foodservices. As a conclusion, there should be efforts to improve the QOL of target customers through foodservice quality management.

  • Purpose: This study was to identify factors affecting mammography screening behavior in job women by attitude, social influence and self-efficacy model. Methods: The data were obtained from 171 job women in one residency area by structural questionnaire from March to June 2013 and analysed by using $x^2$-test, ANOVA, Spearman's correlation and logistic regression analysis. Results: The each performance rate was 45.1% in mammography, 44.9% in breast self examination and 48.5% in physical examination. The mammography performance rate in job women showed higher significance in the groups of 1) older age, urban residency, marital status or high economic state, 2) shorter office hours or higher job position, 3) childbirth experience or menopause and 4) preferring soy bean food, practicing regular exercise, suffering chronic disease or receiving radiation therapy. Attitude, social influences and self-efficacy made significant differences in mammography performance. Logistic regression analysis showed that 50 years or older, urban residency, social influences towards mammography and high self-efficacy were significant relationship. Conclusion: In order to increase the mammography performance rate, the intervention strategies are needed to increase positive social influences or self-efficacy and to offer public information to younger age.
