본 연구의 목적은 중소병원 임상간호사들의 대인관계 문제, 자기효능감이 행복감에 미치는 영향을 확인하 고, 임상간호사들의 대인관계 문제와 자기효능감을 향상시켜 행복감을 증진시키기 위한 대인관계 대처 프로그램, 및 자기효능감, 행복감 향상을 위한 중재전략을 마련하는데 기초자료로 활용하고자 시도되었다. 본 연구는 중소병원 간호사 154명을 대상으로 한 서술적 상관관계 연구이다. 연구결과 대인관계문제의 경우 미혼, 자녀가 없는 경우에 높았고, 자기효능감의 경우 40대이상, 대학원 이상의 학력, 자녀 3명 이상, 근무경력 20년 이상, 직위는 선임간호사 이상에서 높았다. 대인관계문제와 자기효능감은 유의한 음의 상관관계가 있었으며(.r=-.58, p<.001), 대인관계문제와 행복감은 유의한 음의 상관관계가 있었다(.r=-.50, p<.001), 자기효능감과 행복감은 유의한 양의 상관관계가 있는 것으로 나타났으며(r=.61, p<.001), 간호사의 행복감에 가장 큰 영향을 미치는 것은 자기효능감으로 나타났다(β=.43, p=<.001). 본 연구결과를 토대로 간호사의 행복감을 증진시키기 위해 자기효능감을 높일 수 있는 근무여건과 프로그램들을 제공할 필요가 있다. The purpose of this study was to confirm the effect of interpersonal problems and self-efficacy on happiness of clinical nurses in small and medium-sized hospitals. This study attempted to use it as basic data to prepare an interpersonal coping program to improve happiness by improving interpersonal problems and self-efficacy of clinical nurses, and an intervention strategy to improve self-efficacy and happiness. This study is a descriptive correlation study of 154 nurses in small and medium-sized hospitals. The results showed that the respondents who were unmarried and who had no child scored higher for interpersonal problems; In the case of, self-efficacy those who were in their forties or older, who are graduate school alumni or at higher education levels, who had ≥3 children, who had ≥20 years of career, and who were at the senior nurse's position or higher scored higher for self-efficacy. The interpersonal problems were significantly negatively correlated with self-efficacy (r=-.58, p<.001); the interpersonal problems were significantly negatively correlated with happiness (r=-.50, p<.001); self-efficacy was significantly positively correlated with happiness (r=.61, p<.001); and self-efficacy had the most substantial impact on happiness among nurses (β=.43, p=<.001). Based on these results, it is necessary to provide working conditions and programs that can help improve nurses' self-efficacy.

Grain yield, agronomic traits, and correlation between genetic distance of 36 F1 hybrids produced by half-diallel crosses using nine maize inbred lines were analyzed. In the analyses of F1 hybrids and their mid-parent heterosis (MPH) for agronomic traits, grain yield showed highest MPH value of 156%. One-hundred kernel weight showed the lowest value of 7%. In addition, when genetic distance based on agronomic traits was estimated, parental inbred lines did not agree with their own pedigree. Therefore it had the limitation to estimate genetic distance using agronomic traits. In this study, 92 SSR markers were used to calculate genetic distance at DNA level. However we did not confirm their own pedigree of nine parental inbred lines. There was no correlation between grain yield and SSR markers. Therefore molecular marker selection was conducted in relation with grain yield by the step-by-step method using 92 SSR markers. The selected nine SSR markers showed a significant positive correlation (r2=0.703**) between grain yield and SSR markers. The correlations between the selected SSR markers and agronomic traits of ear length, ear width, plant height, and ear height were particularly showed positively correlated. The nine SSR markers selected in this study would help predicting heterosis and planning crosses for hybrids in maize breeding programs.

In order to develop a core set and new corn variety in Korea, we evaluated the morphological characteristics of 194 maize accessions by examining eight quantitative characteristics. On the evaluation of quantitative traits for 194 maize accessions, they showed the morphological variations in tassel length (35.1±5.0 cm), plant height (226.1±33.7 cm), ear height (86.3±22.6cm), stem diameter (2.3±0.6 cm), leaf width (9.3±1.1 cm), ear length (14.5±2.4 cm), ear row number (14.1±1.9 row), and 100 kernel weight (24.9±4.4 g). The results of principal component analysis (PCA) indicated that the tassel length, plant height, and ear height greatly contributed to positive direction on the first principal component axis. One-hundred kernel weight contributed to negative direction on the second principal component axis. Thus these morphological characteristics, which contributed greatly in the first and second principal components, might be useful for discrimination among 194 maize accessions. In our study, seven accessions, such as IT026357, IT026441, IT027321, IT033271, IT033591, IT033597 and IT124273, particularly were measured high on yield-related traits. Consequently, the 194 maize accessions used in this study could be used as promising materials for maize breeding programs such as development of new hybrid in Korea.
