The aim of the study was to evaluate of the knowledge, behavior and health beliefs of individuals over 50 regarding colorectal cancer screening, with a descriptive and cross-sectional design at Karabuk Life and Health Center in Turkey. A total of 160 people meeting set criteria were included in the study. The questionnaire consisted of two parts. The first part was composed of questions on characteristics of participants and the second part of questions derived from the Champion's Health Belief Model Scale. Only 15.0% of participants (n=24) had undergone a fecal occult blood test (FOBT), 11.3% (n=18) had had colonoscopy and 4.4% (n=7) had had sigmoidoscopy. Some 90.6% of the participants had low levels of risk awareness about the colorectal cancer. It was found that the average point of severity subscale of participants over 65 is higher than that of participants under 65 (p<0.05). In conclusion, because of the many barriers and health beliefs for the colorectal cancer screening program, the rate of participation in screening programs is not sufficient. Healthcare providers have important responsibilities for increasing rate of attendance in colorectal cancer screening programs.

Purpose: The purpose of this study was to develop a scale to assess the transition shock experienced by newly graduated nurses, and test the validity and reliability of the scale. Methods: The initial items were identified through a review of literature and in-depth interviews with nine newly graduated nurses. Content validation of the items was evaluated by five nurse professors and three nurses. Participants were 269 newly graduated nurses who worked at six acute care hospitals in Busan, Ulsan, and Yangsan, South Korea. Data were analyzed using item analysis, exploratory and confirmatory factor analysis, criterion related validity, and internal consistency. Results: The final scale consisted of 18 items and six factors (conflict between theory and practice, overwhelming workload, loss of social support, shrinking relationship with co-workers, confusion in professional nursing values, and incongruity in work and personal life), which explained 71.3% of the total variance. The six subscale model was validated by confirmatory factor analysis. Cronbach's alpha for the total items was. 89. Convergent validity was evaluated by analyzing total correlation with burnout (r=.71, p<.001) and turnover intention (t=5.84, p<.001). Conclusion: This scale can be used in the development of nursing interventions to reduce the transition shock experienced by newly graduated nurses.

It is important to examine patients' subjective evaluation as well as objective measures and clinician's rating to assess voice disorders. This study aimed to evaluate validity and reliability of Korean-version of Voice Handicap Index (KVHI) and Voice-Related Quality of Life (KVQOL) with 113 adults with voice disorders and 111 normal adults. Content validity was verified by three experienced speech-language pathologists. Concurrent validity was revealed by examining the correlation among KVHI, KVQOL, and Voice Rating Scale as well as item discrimination coefficients. Total scores of KVHI and KVQOL of adults with voice disorders were significantly different from those of normal adults. Test-retest reliability and internal consistencies were significantly high in both KVHI and KVQOL. Correlations among scores of each subscale and total score were also significantly high in each tool. The study revealed that KVHI and KVQOL are suitable tools to be used in clinics and research areas in Korea, which can subjectively evaluate the effects of voice disorders on daily life as well as on quality of life.

Purpose: The purpose of this study was to develop and test the validity and reliability of the Korean version of the Contraceptive Self-efficacy (K-CSE) scale. Methods: The K-CSE scale was developed through forward-backward translation methods. Construct and criterion validity and internal consistency reliability were calculated using SPSS/WIN 21.0. Data were collected from 257 women students from two universities in G city, South Korea. Results: The factor structure of the K-CSE scale showed the cumulative variance as 62.9% in the factor analysis. Factor loading of 13 items on four subscales ranged from .47 to .88. Factors were named as 'initiative of contraceptive use', 'sexual assertiveness', 'refusal of sexual intercourse', and 'autonomic sexual behavior'. Criterion validity compared to the Sexual Autonomy Measurement (SAM) showed significant correlation. Cronbach's ${\alpha}$ for the reliability of each subscale were .50~.82 and .76 for the total scale. Conclusion: The findings of this study demonstrate that the K-CSE scale is a satisfactory valid and reliable scale. Therefore, the CSE scale can be useful in measuring contraceptive self-efficacy among women university students in Korea.

Purpose: The purpose of this study was to identify the relationship between Health Locus of Control(HLOC) and Health Promoting Behaviors(HPB) in the nursing college students. Method: Data were collected by the structured questionnaires from 485 nursing students in Gwangju. Data were analyzed by using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and Simple regression. Result: The mean score for the HLOC of the nursing students was Internal: 23.858, Powerful others: 17.619, Chance: 15.076. The total mean score for HPB was 2.45(range 1-4). The highest score on the subscale was self-actualization(M=2.914), and the lowest was health responsibility(M=1.905). The score between HPB and HLOC-internal(r=.302, p=.000), HLOC-powerful others (r=.329, p=.000), HLOC-chance(r=.146, p=.001) showed a significantly positive correlation. By means of simple regression analysis, HLOC explained 14.3% of HPB. Conclusion: This study suggests that HLOC accounted for 14.3 % of HPB in the nursing college students.

This study was conducted to test the reliability and validity of "What my baby is like(WBL)" that was developed by Pridham et al. for measuring infant temperament. 37 subjects were participated four times-1, 3, 6, and 12months, and 146 cases were analyzed. The construct validity for the scale was tested by factor analysis with four factor loading solution based on the previous study. One item was excluded because total-item correlation was too low, so that the number of total items were eighteen. The analysis yielded four well defined factors: amenability and persistence, activity, reactivity, and adaptability. These four factors explained 57.62% of the variance in the infant temperament. The criterion related Validity was confirmed by the relationship between the infant temperament and HOME, and between the infant temperament maternal confidence in childrearing. The reliability of the scale was determined with Cronbach's alpha coefficient and Guttman split-half coefficient. Cronbach's alpha was .86, for 18 items, and Guttman split-half cofficient was .81. In subscale analysis, Cronbach's alpha was .56~.84. In conclusion, WBL showed a high degree of validity and reliability, suitable in Korean infants for measuring temperament. In the further study, it would be necessary to refine the concept of temperament and to analyze the correlation between WBL and other temperament inventory.

This study was conducted to test the reliability and validity of Maternal Self-Report Inventory that was developed by Shea and Tronick for measuring maternal self-esteem. The subjects were 154 mothers. The construct validity for the scale was tested by factor analysis with five factor loading solution based on the previous study. One item was excluded because total-item correlation was too low, so that the number of total items were twenty-five, the analysis yielded five well defined factors: confidence on the maternal role, general ability of maternal role, caretaking ability, readiness on maternal role, and feeling on the pregnancy and deli very. These five factors explained 52.38% of the variance in the maternal self-esteem. Maternal self-esteem was not affected by maternal age, educational level, occupation, religion, delivery type, or parity. The reliability of the scale was determined with Cronbach's alpha coefficient and Guttman split-half coefficient. Cronbach's alpha was .82, for 26 items, and .83 if one item was deleted. Guttman split-half cofficient was .75. In subscale analysis, Cronbach's alpha was .63~.84. In conclusion. Maternal Self-Report Inventory showed a high degree of validity and reliability, suitable in Korean mothers for measuring maternal self-esteem. In the further study, it would be necessary to compare the maternal self-esteem between mothers with normal babies and premature babies, for confirming the criterion-related validity of the inventory.

Experimental study on combustion characteristics of double swirl coaxial injectors has been conducted for the assessment of critical injector design parameters. A reusable, unielement thrust chamber has been fabricated with a water-cooled copper nozzle. Two principle design parameters, a swirl angle and a recess length, have been investigated through hot firing tests for the understanding of their effects on high pressure combustion. Clearly, both parameters considerably affect the combustion efficiency, dynamics and hydraulic characteristics of an injector. Internal mixing of propellants in a recess region increases combustion efficiency along with the increase of a pressure drop required for flowing the same amount of mass flow rates. It is concluded that pressure buildup due to flame can be released by the increase of LOx flow axial momentum or the reduction of a recess length. Dynamic pressure measurements of the thrust chamber show varied dynamic behaviors depending on injector configurations.

The purpose of this study was to find out the relationship between psychosocial well-bing and health promoting lifestyle practices of university students in Korea. The subjects were 282 students of one university in Chung-ju. The data were analyzed by the SAS program using mean, frequency, t-test, ANOVA and pearson correlation coefficient. The major results were as follows: 1. The average score for psychosocial well-being and health promoting lifestyle practices were low at 55.97, 103.5. In the subcategories of health promoting lifestyle practices, the highest degree of performance was interpersonal support(2.77), and the lowest degree was health responsibility(1.49). 2. There weren't statistically significant differences for the Psychosocial well-being according to sociodemographic variables. The performance of health promoting lifestyle practices was significant different according to gender and school year. 3. The Psychosocial well-being was negatively correlated with health promoting lifestyle practices. Also it was negatively correlated with subscale of health promoting lifestyle practices except health responsibility. So, significant correlation between psychoscial well-bing and self-actualization, exercise, nutrition, interpersonal support, stress management was found. Based upon this results, health promoting behavior will be clues for developing a interventional programs and strategies for the health promoting lifestyle practices in university students
