In Korea, visiting nursing services in pubic health centers have been in place since 1991. The purpose of this study is to compare the job characteristics, job motivation and job performance between visiting nurses and other public health nurses. 196 subjects were sent mailed questionnaires from Aug. to Sep., 1997. The response rate was 65.3%. Data were analyzed by a SPSSWIN program with a t-test, $X^2-test$, ANCOVA. The results were as follows : 1. The level of job ability in visiting nurses was higher than that of other public health nurses, but it was an insignificant difference(t=1.5975, p=.2078). Among job characteristics, skill variety was significantly higher in other public health nurses(t=8.2121, p=.0046); autonomy and feedback were significantly higher in visiting nurses(t=8.1877, p=.0047/t=7.7026, p=.0085). 2. There was no significant difference in the level of job motivation(t=.6485, p=.4216) and in job performance between the two groups (t=2.7393, p=.0995). In job performance, general nursing and organizational jobs were significantly higher in other public health nurses (t=4.8486, p=.1288/t=9.4237, p=.0024). 3. It was reconfirmed that there was, a significant difference in the level of skill variety, autonomy and feedback in analyzing age and career as covariates. 4. Significant positive relationship was found in job characteristics and job motivation(r=.5488, p=.0000). No significant relationship was found in job characteristics and job performance(r=.0486, p=.498). Through these results, it was supported that there were differences in some of the job characteristics and job performance between visiting nurses and other public health nurses. Therefore, it is requested to redesign job standards, training programs and management styles focusing on the job characteristics of visiting nurses.

The purpose of this study is to analyze the mediating effect of informatization level between characteristics of introducing information system and organizational performance in hospital settings, and to provide suggestions to improve the performance level of strategic information system of hospitals. In order to achieve study purpose, a causal path model was developed and empirically tested. Data were collected from 746 managers of 92 hospitals keeping information system in Busan, Ulsan and Kyungnam Province using self-administered structured questionnaire. Major results of this study were as follows; The results of the path analysis showed that organizational characteristics variables except informatization strength within health industry had significant effects on informatization level, and had indirect effects on organizational performance mediated by informatization level. On the other hand, informatization level, especially revelation capability among informatization level variables, was found to have significant direct effect on organizational performance. These results of empirical test imply that informatization level variables are both important affecting factors on organizational performance and mediating factors between organizational characteristics and organizational performance. Therefore, in order to increase organizational performance, measures improving informatization level should be developed and carried out continuously. And, especially, focusing on building and strengthening revelation capability is crucial to those efforts.

In this study, It is utilized 103 management panic data about social enterprises in Chungnam area (Chungnam, Daejeon, Sejong) region from 2011 to 2017. The organizational characteristics (organizational type, type of certification, company's region, external grants, paid employees) were set as independent variables with economic performance (sales) and social performance (employment of vulnerable class) as dependent variables. We analyzed the factors affecting the economic and social performance of social enterprises and confirmed the correlation between economic and social performance. The results of this study are as follows: First, the organizational characteristics of social enterprises showed a significant difference in sales as economic performance. External grants have no positive effect on the economic performance (sales) of social enterprises, while paid workers have a positive (+) influence on the economic performance. Second, the organizational characteristics of social enterprises showed significant differences in employment of the vulnerable class, which is social performance. Only the paid workers had a statistically significant relationship with the social performance of the social enterprise. Third, the correlation between economic performance (sales) and social performance (employment of the vulnerable class), which is the result of social enterprise, is shown. This can enhance a social enterprises' sustainable growth and self-sufficiency by improving the employment of vulnerable people, the economic performance of a social enterprise, which is sales and social performance, and ultimately can manifest the value and purpose of the social enterprise.

Performance characteristics of single cell in phosphoric acid fuel cell were studied for various electrode fabrication parameters such as teflon content, electrode structure, thickness of electrocatalyst layer, platinum content and electrode area. The performance of single cell was decided from the measured voltage-current through a load change. The electrode of 40wt.% teflon exhibited high initial performance of single cell, but in the long term operation, the cell performance of 45 wt.% teflon was better. Also the single cell appeared good performance in case of electrodes with duplicate structure, thin electrocatalyst in thickness, more platinum content, and small area. These results of cell performance were discussed as related to the electrolyte flooding, formation of 3 phase boundary area, internal resistance of electrode, and microstructure of electrode.

본 연구는 창업자의 특성이 창업기업의 성과에 미치는 영향을 분석함으로써 창업보육기업의 핵심 성공요인이 무엇인가를 분석하는데 연구의 초점을 두고 있다. 창업자의 특성은 주로 심리적 특성 등을 중심으로 이루어진 선행연구와 달리 창업자의 심리적 특성 이외에 행위적 특성과 경력 특성이 기업 성과에 미치는 영향을 연구하였다. 창업보육센터의 입주기업을 대상으로 실증 분석한 결과 창업자의 심리적 특성 특히 성취욕구와 위험 감수 능력이 높을수록 기업 성과가 높은 것으로 나타났다. 또한 창업자 창업 경험이 풍부할수록 기업 성과가 높은 것을 나타났다. 본 연구의 한계는 표본이 주로 충남지역에 집중되어 있어 향후 연구는 포괄적인 범위에서 연구 대상을 설정하고 아울러 기업 성과에 영향을 미칠 수 있는 다양한 독립변수를 고려한 장기간의 광범위한 추가 연구가 요망된다.

The primary purpose of this study is to examine the interaction effects of organizational characteristics as contextual variables on the relationship between relational exchange characteristics and ASP service performance. The effect of relational exchange characteristics on ASP service performance has been also investigated. For this purposes, we developed a research model based on the literature reviews of ASP services, relational exchange theory, and contingency theory. A total of 106 usable survey responses from companies using ASP services has been analyzed in the study. The findings indicate that (1) flexibility and partnership had a positive influence upon noneconomic profit, (2) information sharing had a positive influence upon economic profit, (3) organizational size and IS maturity had a partial moderating effect on the relationship between relational exchange characteristics and ASP service performance, and (4) the subgroup analysis, conducted to determine the exact nature of interaction effect, reveals that the relationship between relational exchange characteristics and noneconomic profit is significantly stronger with a high level of organizational size than with a low level, and that the relationship between relational exchange characteristics and economic profit is significantly stronger with a low level of IS maturity than with a high level.
