The purpose of this study was determine the relationship between social support and the infertility stress of infertile women. The subjects for this were 64 infertile women living in S city, Kyung Book Province. The data was collected during $4^{th}$ July and $14^{th}$ August, 1988 using the social support scale developed by Park(1985) and the infertility stress scale developed by Kim et. al.(1995) The data analysis was done by descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression using SPSS PC program. The results were as follows. 1. The mean of social support of the infertile women was 3.80. 2. The negative correlation was revealed between social support and the infertility stress(r=-.56, p=.001). 3. Research has revealed that the support need of social support was a predictor of the infertility stress of the infertile women, explaining 30.9% of total variance. 4. the general characteristic variable significantly related to the level of the infertility stress of the infertile women was marriage satisfaction(t=-3.28, p=.004). The results of this study suggest that social support is related to the infertility stress of the infertile women.

Purpose: The purpose of this study was to examine the relationship between spirituality and a fighting spirit among the patients with cancer. Methods: The participants were 223 patients diagnosed stomach, colorectal or breast cancer, and who were in chemotherapy or follow up care. The study design was cross-sectional at the time of the data collection. The degree of spirituality was measured by the Korean version of WHOQOL Spirituality, Religiousness and Personal Beliefs (SRPB) Pilot Test Module, and fighting spirit was measured by the scores of Mental Adjustment to Cancer(MAC) scale. Results: The score of love appeared to be higher in the patients with follow up care than the patients with treatment(p<0.05) and the score of believing was much higher in patients with recurrence than the patients without (p<0.05). There was a statistically significant correlation among hope, believing, love, forgiveness and acceptance, and fighting spirit. In the multiple regression analysis, hope and believing explained much variance of the fighting spirit. Conclusion: These finding showed that the more hopeful and believing patients with cancer had higher scores of fighting spirit, which was known to be one of the most active coping style in adjusting to cancer.

The analysis of variance for randomized block design or two way classification data is well known. In this paper, particularly, we considered two stage nested design in which the levels of one factor is not identical for different levels of another factor. We investigate the structural properties of two stage nested design and the properties of error sum of squares for random effect model. For the application of two way nested design, we consider two-period crossover design which is used commonly for the equivalence test to bio-similar product. The confidence interval estimation of the difference of two population means in the crossover design is discussed based on statistical package SPSS.

The purpose of this study was to evaluate the titanium castability (internal porosity) between pressure type casting machine & centrifugal casting machine with air-vent or not. Internal porosity is a well-known problem in dental titanium casting, resulting in inferior mechanical properties of dental restorations. To evaluate the castability, the square plate was chosen. 40 plate patterns($20{\times}20{\times}1.8mm$)were attached to funnel-shaped sprue. Then 20 plate patterns were attached air-vent. They were invested in titanium investment material and cast in a pressure type casting machine(20castings) and centrifugal casting machine(20castings). Each group were divided with air-vent(10castings) or not(10castings). The titanium castings were evaluated by radiographic photograph for the location of the internal porosities. The percentage porosity of each specimen was determined using standardized digital radiographs. The results were analyzed with analysis of variance and t-test for paired comparison between two groups.

It has been widely discussed in phonology that syllable structure of mother tongue influences one's acquisition of foreign language. However, the topic was hardly examined experimentally. So, we investigated effects of Korean syllable structure when Korean speakers pronounce English words, especially focusing on consonant strings that are not allowed in Korean. In the experiment, all the subjects are divided into 3 groups, that is, native, experienced, and inexperienced speakers. Native group consists of 1 male English native speaker. Experienced and inexperienced are each composed of 3 male Korean speakers. These 2 groups are divided by the length of residence in the country using English as a native language. 41 mono-syllable words are prepared considering the position (onset vs. coda), characteristic (stops, affricates, fricatives), and number of consonant. Then, the length of the consonant cluster is measured. To eliminate tempo effect, the measured length is normalized using the length of the word 'say' in the carrier sentence. Measurement of consonant cluster is the relative time period between the initiation of energy (onset I coda) which is acoustically representative of noise (consonant portion) and voicing. bar (vowel portion) in a syllable. Statistical method is used to estimate the differences among 3 groups. For each word, analysis of variance (ANDY A) and Post Hoc tests are carried out.

Objectives : The purpose of this study was to identify the determinants of the long-term influence of violence on hospital nurses. Methods : Three-hundred hospital nurses were recruited in B city, South Korea. They were asked to complete a questionnaire, and 282 data- sets were included in the multiple regression analysis. Results : Subjects experienced more episodes of verbal violence than that of physical threats or physical violence. Assailants tended to be patients and their caretakers rather than internal customers. Nurses who had religion, worked in a surgical ward, and a 3-6 year career perceived a high level of violent experiences compared to their counterparts. The determinants of the long-term influence of violence were physical violence (t=-2.705, p=.007), emotion-focused coping (t=3.049, p=.003), and emotional response (t=3.611, p<.001). The model was statistically significant explaining 13.0% of the variance (F=14.981, p<.001). Conclusions : Nurse managers should help nurses who are victims of hospital violence by teaching them not to depend on emotion-focused coping and by alleviating their emotional response to violence.

PURPOSE. The most common failure seen in restorations with a zirconia core is total or layered delamination of the ceramic veneer. In the present study, the shear bond strengths between veneering ceramics and colored zirconia oxide core materials were evaluated. MATERIALS AND METHODS. Zirconia discs ($15{\times}12{\times}1.6mm$) were divided into 11 groups of 12 discs each. Groups were colored according to the Vita Classic scale: A3, B1, C4, D2, and D4. Each group was treated with the recommended shading time for 3 s, or with prolonged shading for 60 s, except for the control group. Samples were veneered with 3 mm thick and 3.5 mm in diameter translucent ceramic and subjected to shear test in a universal testing machine with a crosshead speed of 1 mm/min. One-way analysis of variance (ANOVA) and Tukey's HSD tests were used for comparisons of the groups having the same shading times. A paired t-test was used for groups of the same color (3 s/60 s). RESULTS. Among the 11 groups investigated C4 (3 s) had the highest bond strength with a value of 36.40 MPa, while A3 (3 s) showed the lowest bond strength with a value of 29.47 MPa. CONCLUSION. Coloring procedures can affect zirconia/ceramic bond strength. However, the results also showed that bond strengths of all the investigated groups were clinically acceptable.

The purpose of this research was to find out the most explainable variables influencing fashion leadership. This research was carried out by both the theoretical and empirical study. For the theoretical study, the research of fashion leadership was based on the fashion opinion leadership and innovativeness. The study included the analysis of variables influencing fashion leadership, such as clothing importance, clothing conformity, clothing anticonformity, perceived risk of clothing, use of fashion information source and demographic variables. For the empirical study, fashion leadership was measured by fashion opinion leadership and innovativeness. The variables influencing on the fashion leadership were measured by self-image, social participation, clothing behaviors(clothing importance, normative conformity, identificational conformity, clothing anticonformity, clothing independance), demographic variables(major fields of students, year of education, family income). Data were obtained from 335 female college and university students in Chung-Buk area by self-administered questionaire. The data collected through the questionaire were analyzed by the stastical thechique-stepwise regression. The results of the study were as follow: 44.6 percent of the total variance of fashion leadership was explained by the five variables: Clothing importance, use of marketer-dominated fashion information source, identificational conformity, traditional-modern self image and clothing anticonformity. Family income and the major fields of students are significantly related to the fashion leadership.
