This study was conducted to describe the attitude toward pressure ulcer prevention, knowledge and non-compliance risk for pressure ulcer prevention practice and degrees of nursing performance, as well as to examine the relationship among these variables. To accomplish this, we invited 397 nurses from four hospitals to complete surveys of attitude toward pressure ulcer prevention, knowledge and certainty for pressure ulcer prevention practice, and degrees of nursing performance. Non-compliance risk for pressure ulcer prevention practice was derived from the difference between knowledge and certainty for pressure ulcer prevention. The data were collected from March to June 2017 and analyzed by descriptive statistics, independent t-tests, ANOVA, and partial Pearson's correlation coefficient testing. The correct answer rate regarding the knowledge of pressure ulcer prevention practice was 79%, and the degree of pressure ulcer prevention nursing performance was $2.46{\pm}0.31$. The highest item of the non-compliance risk for pressure ulcer prevention practice was incontinence diapers prevent incontinence-associated dermatitis. There were significant negative correlations between non-compliance risk for pressure ulcer prevention practice and knowledge (r=-0.25, p<0.001), and degree of pressure ulcer prevention nursing performance (r=-0.13, p=0.009). Continuous education and furnishing practical guidelines for pressure ulcer prevention should be implemented to improve knowledge and certainty of pressure ulcer prevention practice.

A Major aim of this study is to test the hypothesis that there is an association between empowerment, organizational memory, and new product creativity. In addition to exploring these relationships, this study examines the effect of new product creativity on new product performance, and identify the moderating effects of market uncertainty in the relationships between new product creativity and performance. For this purposes, we developed a research model based on the literature reviews of empowerment, organizational memory, market uncertainty, and new product creativity. A total of 121 usable survey responses has been used in the empirical research for foods manufacturing industry. The findings indicate that (1) Empowerment has a positive effect on new product creativity, (2) Organizational memory has a positive effect on new product creativity, (3) New product novelty has a positive effect on new product performance, and (4) Only competition uncertainty has a moderating effects between the new product meaningfulness and performance. The findings have implications for managers wishing to acquire the new product creativity and to better the new product development performance.

Recently, domestic universities have emphasized career path to start-up through entrepreneurial self-efficacy (ESE) and entrepreneurship. The purpose of this study is to investigate the effect of ESE on entrepreneurship of university students. Also we examine the moderating effects of entrepreneurial education and career uncertainty between ESE and entrepreneurship. Research sample consisted of 236 university students in Cheonan city. The results of this research is as follows: First, ESE showed a positive effects on entrepreneurship. Second, the moderating effect of entrepreneurial education was significant on the relationship between ESE and entrepreneurship. In other words, university students with a higher entrepreneurial education showed higher entrepreneurship when ESE was lower. But students with a lower entrepreneurial education showed higher entrepreneurship when ESE was higher. Finally, the interaction effects of career uncertainty was confirmed in relationship between ESE and entrepreneurship. In other words, university students with a higher career uncertainty showed higher entrepreneurship when ESE was higher. But students with a lower career uncertainty showed higher entrepreneurship when ESE was lower. In order to improve the entrepreneurship of the pre-founders, it is necessary to strengthen the behavior control of university students by enhancing the ESE. Also, the improvement of entrepreneurship of pre-founders should strengthen the ESE of university students, and should complement systematic and effective entrepreneurship education. In particular, we should provide the stability for career decision by eliminating uncertainty about the career path of university students.

This note presents the robust root clustering problem of interval systems whose characteristic equation might be given as either a family of interval polynomials or a family of polytopes. Corresponding to damping ratio and robustness margin approximately, we consider a certain class of D-region such as parabola, left-hyperbola, and ellipse in complex plane. Then a simpler D-stability criteria using rational function mapping is presented and prove. Without .lambda. or .omega. sweeping calculation, the absolute criteria for robust D-stability can be determined.

This paper investigates how small-medium firms deploy organizational culture, job stability and environmental uncertainty for technological innovation(product and process innovation). This paper suggests that organizational culture has significant effects on technological innovation, that job stability and environmental uncertainty moderate relationship between organizational culture and technological innovation. To test the hypotheses, data were collected from small-medium firms. The survey data of 258 firms were collected and integrated as the empirical base for testing the hypotheses. Major results are as follows: Firstly, when organizational culture as well as control variables are considered, organizational culture had significant and positive effects on product innovation. This result implies that organizational culture is an important means by which small-medium firms can promote innovation. Secondly, the interaction between organizational culture and job stability had a positive and significant effects on product innovation. Thirdly, the interaction between organizational culture and environmental uncertainty had a positive and significant effects on product innovation and process innovation. This paper suggests implications and several future researches need to overcome the limitations of this paper.

전통적인 산업조직이론에서 널리 사용되는 시장구조-행동-성과 분석 도구 (The SCP Paradigm)는 시장성과가 가격정책, 기술개발투자(R&D), 광고투자, 생산설비 변경 등 시장행동의 함수라는 암묵적 가정에 근거한다. 최근 시장행동 중에서 기업의 관심이 크게 높아진 R&D 및 광고투자가 시장성과에 미치는 영향이 크게 부각되었으며, 시장성과를 구성하는 주요요인으로 주목받고 있다. R&D 및 광고 투자의 성격과 행태, 그리고 시장성과에 미치는 영향이 상호 유사함에도 불구하고 두 가지 변수를 동시에 다룬 연구는 매우 드물다. 몇 안 되는 연구들도 기업의 행태를 실증적으로 설명하는데 치중함으로써 이론적 근거를 소홀히 하는 경향을 보이고 있다. 즉, 논리의 전개상 이론적인 근거를 바탕으로 수리모형이 먼저 제시된 후에야 이를 검증하는 방법으로 통계모형을 사용하는 것이 옳을 것이다. 이 논문은 기존의 SCP 분석방법을 사용하여 기업이 한정된 재원을 어떤 원칙아래 R&D 및 광고에 분산 투자하는 가를 설명하기 위해 수리모형을 설정한 후, 정태와 동학, 확실성과 불확실성, 단발성과 균등투자전략의 개념을 도입하여 다양한 분석을 시도하였다. 또 R&D 및 광고투자 함수를 이론적 근거에 의해 도입하되, 각 모형에 균형이 존재하는가를 검증하였다. 수리모형을 이용해 분석한 결과 (1) 기업의 투자는 R&D 및 광고투자간에 한계원리(Marginal Principle)가 지켜지도록 분배할 때에 효율적임이 판명되었고, (2) 동학모형이 정학모형을 포함하는 일반모형의 성격을 가지고 있었으며, (3) 투자는 확실성이 높을수록, 분산시킬수록 투자효과가 큰 것으로 나타났다. 한국을 대상으로 한 실증적 모형추정은 앞의 수리모형 및 그 결과에 근거를 두었으며, 한국기업에 적절한 R&D 및 광고투자함수를 추정한 뒤 이를 이용해 업종, 기업규모, 상품유형별로 적합한 모델(Fixed Effects Model)을 결정하고, 각각에 해당하는 통계모형을 구축하였다. 이 결과 (1) 업종 및 기업규모별로 그룹간에 유의한 특성이 발견되었으며, (2) R&D 및 광고투자는 기업의 시장성과를 설명하는 중요한 변수이나, (3) R&D 투자의 경우는 광고에 비해 불확실성이 존재하는 것으로 나타났고, (4) 수리모형에서 도출된 한계원리가 통계모형에서도 유효한 것으로 드러났다.

Notwithstanding the big potential benefits from interorganizational information systems (IOS), not very many companies have realized these benefits. In an attempt to explain this phenomenon, this study proposes a new construct of IOS asymmetry which refers to the asymmetry in information transparency between supply chain (SC) partners. When there is IOS asymmetry in SC relationships, IOS may not facilitate seamless information exchange among SC partners. Instead, IOS asymmetry may result in SC inefficiencies due to a lack of information sharing. The objective of this study is to empirically investigate whether IOS asymmetry exists in practice and whether it influences SC performance negatively. The data was collected from 130 matched pairs of upstream SC partners in manufacturing industries. The results show that IOS asymmetry indeed decreases overall SC performance. Also, the relationship between IOS asymmetry and SC performance is strengthened under the conditions of high environmental uncertainty.

As the importance of technology protection is emphasized day by day, various protection measures are being carried out to protect technology. But attempts to leak technology are continuing. As an alternative to this, stronger punishment is socially required for technology leakage crimes. In response to these social demands, the standard for punishment has been steadily raised. Legislative bills containing additional reinforcement are still pending in the National Assembly. However, in order to substantially enhance the deterrence against crime, it is not enough to strengthen the punishment standards. The effect can only be fully exercised when the certainty of punishment increases. Therefore, this paper focused on seeking ways to increase the certainty of punishment under the current system rather than the reinforcement of the punishment itself. The purpose of this study was to derive the reason why the innocence rate in technology leakage criminal cases is higher than that of general criminal cases by analyzing cases and causes of innocent cases in technology leakage criminal cases. Based on this, I discussed improvement considerations to reduce unfair acquittal cases.
