This study has reviewed the representative papers on equivalence scale. The purposes of this study are to show applicability of equivalence scale to our country and to develop these estimation methods. This paper is composed of ① introduction, ② classification of equivalence scale estimation methods, ③ studies in our country and ④ the problems and application. 1) Introduction: This part obseIves the outline of this paper. 2) Classification of equivalence scale estimation methods: Equivalence scale estimation met- hods are generally devided into the estimation methods of prais-Houthakker and Blokland. One is based on translog indirect utility function theory, another is based on life cycle theory. 3) Studies in our country: This part introduces representative two papers on the estimation method of household equivalence scale and presents the results. 4) The problems and applications: This part descrives the problems of estimation model and applicability of household equivalence scale.

본 연구에서는 시장환경의 변화에 대응하여 새로운 경영혁신 수단으로서 조직에 도입되고 있는 균형성과정보의 사용정도에 대하여 시장 환경의 제반 특성이 미치는 영향과 함께 균형성과정보의 사용정도와 기업성과의 관련성을 분석하였다. 기업규모를 통제변수로 하고 시장환경의 특성을 시장경쟁, 시장불확실성, 시장성장성 및 시장점유율 등의 다양한 차원으로 측정한 독립변수를 사용하여 균형성과정보의 사용정도를 종속변수로 한 다중회귀모형 다중회귀모형의 분석결과, 시장점유율, 시장경쟁, 시장불확실성 및 시장성장성 변수는 모두 균형성과정보의 사용정도에 대하여 통계적으로 유의한 양의 관계를 나타내었다. 이에 따라 기업의 시장환경은 균형성과정보의 사용정도에 영향을 미치는 것으로 평가할 수 있다. 균형성과정보의 사용정도는 또한 기업성과에 유의한 영향을 미치는 것으로 분석되어 균형성과정보의 사용정도가 높을수록 기업성과는 높게 나타난다고 볼 수 있다. This study analyses the impact of market factors on BSC usage and it s relationship to the firm performance. BSC is introduced as a means of efficient strategic tools for business responding to rapid environmental changes of today. The size of firm is used as a control variable in a Multi-regression model in which four independent variables of market competition, market uncertainty, market growth, and market share are used and regressed on the dependent variable of BSC usage. According to the Analysis results, all market variables give significant statistical influence on BSC usage. BSC usage also has significant statistical influence on the firm performance. It is interpreted therefore that market environment facts are related to the BSC usage which gives ultimate impact on the firm performance.

장대레일 궤도 구조는 사용성 및 유지보수 측면에 장점이 있어 최근 일반적으로 사용되고 있다. 그러나 궤도와 교량의 상호작용에 의한 장대레일의 좌굴 및 파단 등의 안정성 문제가 발생되고, 따라서 국내외 설계 기준에서는 부가축력과 변위에 대한 제반 규정 및 해석절차를 제시하고 있다. 하지만 하중분리해석은 하중 재하 단계에 따른 종방향 저항력의 변화를 고려하지 못하며 또한 비선형 거동을 보이는 궤도에 중첩의 원리를 허용함에 따라 과다한 레일 응력이 산출되어 비경제적 설계를 하게 된다. 따라서 본 논문에서는 Abaqus Model Change 기법을 통한 하중 단계별 종방향 저항력 변화 및 궤도의 비선형성을 고려하는 완전한 해석을 성공적으로 수행하였다. The Continuous Welded Rail (CWR) is being used commonly these days for it’s strength of usability and maintenance. But by the interaction of track-bridge some stability problem such as buckling or fracture occurs on CWR so that domestic and international design criteria shows the regulation and analysis procedure of the additional stress and displacement. However simplified separate analysis method didn’t consider the changes of longitudinal resistance of track according to the load case and allowed the principle of superposition on the track that shows nonlinearity. That produces excessive rail stress and make the design uneconomical. So in this paper, complete analysis that considered the changes of longitudinal resistance and nonlinearity of track using ABAQUS Model Change techniqeu had been successfully implemented.

This study analyses the mediating effect of business strategy on the relationship of internal marketing and business performance of hotel corporations. According to the result, both differential strategy and low price strategy of hotel corporations have mediating effects on the balanced performance financial, customer, internal process and learning and growth perspectives. This result supports suggestions from current research that internal marketing is a key factor of business performance and also suggest that interaction of internal marketing and strategy are related in the process of achieving business performance. Therefore, hotel corporations recognize the importance of internal market concept where competence of employees is regarded as a source of competition superiority and consider internal marketing as the strategic tool for management. The analysis result in terms of balanced performance propose various research hereafter that involve diverse performance indices and strategy variables for business performance area of hotel corporations.

This study analyzes the structural relationships among internal marketing, employee satisfaction, and turnover variables for the purpose of suggesting efficient empirical data that would be useful for human resource management of food service companies. According to the result of analyses, internal marketing of food service companies improves employee satisfaction and decreases turnover rate. Additionally, it is identified that internal marketing gives indirect impact on turnover decrease via improved employee satisfaction. These results supports suggestion from extant research that internal marketing and turnover variables are conceptually related. These empirical data can be used for the basis of practical tools for employee management and performing additional research of related issues.
