The foundation of any association or organization should include a mission, a vision, and strategic goals. Vision and mission are frequently discussed in academic and practitioner literature and accepted as key items in strategic decisions. But in these days, the words“change and crisis”are what companies are familiar with. They bringing about uncertainty led the companies to search for new strategies in order to specify their directions. In case of making proper direction for some organization, the role of management philosophy is most important. And also identifying, clarifying and communicating the management philosophy is now a major part of the planning process. This study examines the characteristics of management philosophy items which including mission and vision in Korean fisheries business with contents analysis. in order to achieve these purpose, this research analysing the mission, vision and CEO’s greeting with the social network analysis(SNA) which is the most dominant technique in contents analysis. The SNA is evaluated that most popular, rigorous and firm methodology for analyzing, examining and revising some concepts or objects in the context of semantics. The findings of social network analysis show that some critical problems are existed. First, most of the fisheries company did not fully announce the mission and vision irrespective of one’s size or scale. Second, there is some coverage insufficiency of stakeholders in mission and vision. And cutting edge topics like environmental problem, corporate social responsibility, consumer sovereignty are not included in management philosophy.

본 연구에서는 인천광역시의 37개 사업장(공장)을 대상으로 작업현장의 소음을 측정 및 분석하여 소음이 화재경보음 인지에 미치는 영향을 분석하였다. 측정결과 평균소음이 95.8dB(A)나왔다. 이는 국내 경보장치 음량기준(화재경보음 발생장치에서 1m떨어진 곳에서 90dB이상)보다 5.8dB(A)높게 나왔다. 미국방화협회(NFPA)에 따르면 암소음(기기음)이 85dB(A)이거나 이상일 경우 화재경보음 인지정도가 미흡하기 때문에 다른 방법을 강구하도록 되어 있다. 또한 화재경보음은 암소음보다 15dB(A) 높아야 한다고 하고 있다. 따라서 주변의 환경을 무시한 획일적인 화재경보음 설계에 대해서 제도적 및 법적 개선이 필요하다고 사료된다.

BaTiO3/epoxy composites have been widely investigated as promising materials for embedded capacitors in printed circuit boards. It is generally known that the dielectric constant (K) of the BaTiO3/epoxy composites increases with improvement of the dispersion of BaTiO3 particles in the epoxy matrix that comes from adding surfactant. The influences of surfactant addition on the dielectric properties of the BaTiO3/epoxy composites are reported in the present study. The dielectric constant of the BaTiO3/epoxy composites is not significantly affected by the surfactant addition. However, the temperature coefficient of capacitance increases and the peel strength decreases as the amount of added surfactant increases. The influences of surfactant addition on the dielectric properties of the neat epoxy are also very similar to those of the BaTiO3/epoxy composites. The residual surfactant in the BaTiO3/epoxy composites affects the temperature coefficient of capacitance and the peel strength of the epoxy matrix, which in turn affects the temperature coefficient of capacitance and the peel strength of the BaTiO3/epoxy composites.
