본 연구에서는 동물복지형 축산물의 경제적 가치를 국내외의 선행연구를 통하여 알아보고자 하였다. 이 연구를 위하여 국내 외에서 발간된 다양한 연구결과를 참고하였다. 분석결과 국내 외 모두 이 분야에 대한 연구가 그리 활발하지 않다는 점을 발견하였다. 분석은 소고기, 돼지고기, 닭고기, 칠면조고기 등의 육류와 계란에 대한 소비자들의 의식조사가 주를 이루고 있었다. 여기에 사용된 데이터는 설문조사를 통한 데이터가 주를 이루고 있었으며, Lexis-Nexis databases, 소고기, 돼지고기, 가금육, 비육류 식품에 대한 분기별 소비량과 소비자가격, 그리고 경매실험을 통한 데이터 등이 사용되었다. 한편, 분석모형으로는 Random parameters logit and latent c1ass model, WTP 분석, Roterdam model, Pearson's Chi test, Mann-Whitney U-test, Kruskal-Wallis test, structural equation model, 회귀분석, Target-costing, 그리고 conjoint 분석 등이 사용되었다.

기업들에 있어서 고용은 혁신활동의 결과를 바탕으로 하는 연속된 의사결정과정이다. 따라서 기술혁신을 통한 고용성과를 살펴봄에 있어서 이 같은 관계성을 명시적으로 분석에 고려할 필요가 있다. 이러한 문제의식을 바탕으로 본 연구에서는 중소기업의 기술혁신과 고용효과의 관계를 선행 연구와 같이 단일방정식을 추정하는 순위로짓(ordered logit) 모형으로 분석할 뿐 아니라, 연립방정식을 추정하는 외견무관회귀(SUR) 모형을 활용하여 실제 동시적으로 수행되어지는 기술경영 과정의 상관성을 반영하여 기업의 혁신활동과 기술혁신 성과, 보상제도 그리고 고용 창출의 구조적 관계를 분석하고자 하였다. 분석 결과, 보상제도의 시행은 기술개발 및 기술사업화 성과를 높이고, 이것은 다시 기업의 고용을 촉진하는 구조적 관계를 확인할 수 있었다. 특히 고용성과에 있어 기술개발 뿐 아니라 사업화 성과가 일종의 허들로 작용한다는 점에서 기술혁신을 프로세스 관점에서 관리할 때 기업의 고용성과는 높아진다고 볼 수 있겠다.

최근 전세계적으로 환경에 대한 관심이 커지고, 국제사회가 '탄소중립'을 선언하면서 '탄소'를 고려한 다양한 수단선택모형 연구가 실시되고 있으나, 탄소에 대한 개인성향을 반영한 연구는 미비한 실정이다. 따라서, 본 연구에서는 탄소저감형 이동수단(전동킥보드 등)을 포함한 대중교통 서비스로 SPT(Sustainable Public Transit)라는 새로운 수단을 제시하고, 수도권 통근자를 대상으로 실시한 SP(Stated Preference)조사를 활용하여 요인분석을 통해 응답자의 탄소에 대한 개인성향을 분석한 후, 다항로짓모형을 활용하여 SPT에 대한 수단선택모형을 구축하였다. 분석 결과, SPT 잠재선호에 영향을 미치는 요인으로 성별, 소득, 개인성향('새로운경로 탐색에 대한 열정', '수단간 환승 선호', '탄소저감지식', '탄소저감실천') 변수가 유의한 것으로 나타났다. 따라서, 본 연구는 수단선택모형 구축시 수단의 속성변수로 탄소배출량을 선정하거나, 탄소저감과 관련한 개인성향 변수를 구축했다는 부분에서 의의가 있다.

At present time, industrial accidents statistics are used as the basic data of the policy to prevent industrial accidents and the plan to applicate the industrial accident insurance. But this statistical data is not sufficient for the effective safety management because it is the expression of the itemized distribution and the frequency for the whole cases. This study tried to correlational analysis for each causes by defining investigational items as their accident parameters. The correlational analysis, between the unsafe action and status and their relational causes, was performed to analyze the occurrence causes of industrial accident. And to assume the severity of accident, the correlativity and independency between causes and direct causes which are defined hospital days subordinate parameter were analyzed. In addition, this study expressed numerically the effectiveness of subordinate parameters depended on the level of independent parameter by presenting the predictive model between dependent parameter and independent parameter, which have the categorical parameter, through the Logit analysis method.

The objective of this paper is to analyze consumers' consumption behavior of environment-friendly mandarin and attributes of mandarin in Korea. It is also to measure consumers' marginal willingness to pay by the attributes of mandarin and to estimate the market-share by products of mandarin from the data surveyed by a survey research company. The questionnaires for consumers were given randomly by interview to 500 married women lived in Seoul and to 200 wholesaler in Seoul, Busan, Daegu, Kwangju. The conjoint analysis method was used to analyze consumers' preference and suggest several implications for the rational production and marketing policy of mandarin.

The objective of this research is to quantitatively valuate the economic value of analysis model related to climate change mitigation and adaptation. Due to the fact that the subject of this research, which is the Korean climate change mitigation and adaptation model, has not been actualized, a conjoint analysis applying stated preference data has utilized. As results, among the many attributes considered in this research, the value of the attribute related to reflecting Korea's current situation is analyzed to be largest in both greenhouse gas (GHG) mitigation model and climate change adaptation model. Additionally, if all the considered functional aspects are assumed to be feasible, the economic value of the Korean GHG mitigation model is assumed to be 60.3 billion Korean won(KRW) and the Korean climate change adaptation model is assumed to be 51 billion KRW.

The detection of corporate failures is a subject that has been particularly amenable to cross-sectional financial ratio analysis. In most of firms, however, the financial data are available over past years. Because of this, a model utilizing these longitudinal data could provide useful information on the prediction of bankruptcy. To correctly reflect the longitudinal and firm-specific data, the generalized linear model with assuming the first order AR(autoregressive) process is proposed. The method is motivated by the clinical research that several characteristics are measured repeatedly from individual over the time. The model is compared with several other predictive models to evaluate the performance. By using the financial data from manufacturing corporations in the Korea Stock Exchange (KSE) list, we will discuss some experiences learned from the procedure of sampling scheme, variable transformation, imputation, variable selection, and model evaluation. Finally, implications of the model with repeated measurement and future direction of research will be discussed.

Using the National Children and Youth Panel Survey (2010) data, this study examines the self-care after school experienced by elementary school students. It argues the necessity of analysis on self-care days for understanding demanders' characteristics of after-school care policy. Based on the Ordered Logit Model, this study analyzes the determinants of self-care days among school-aged children. The main result of the analysis is that self-care days are also more likely to be increased among children with higher school grade, more sibling, lower mother's education, dual-earner family, two-parent family, multi-cultural family, and lower family income.

An investigation is given to a behavioral analysis of automobile users applying congestion toll theory for the purpose of maintaining the efficiency of transportation system. A case study is performed for the city of Seoul, where modal split behavior of automobile user groups is analysed in various level of congestion toll. Automobile users are grouped with respect to their income levels and work shift times. Automobile user behavior is then explained against the field data. A Logit-type model is applied for modal split changes through the application of congestion toll. It is found in the case study that the users in the monthly income bracket of 1.0~1.5 million won is the most predictable group whose work travel time begins 7:00~9:00 a.m. It is also found in the study that 1,000~1,500 won of congestion toll whould reduce the auto use as much as 5%.

The purpose of this study was to analyze the state of the living arrangement plan, the housing plan, and economic plan for elderly's life and contributing factors to their life plan. The sample in this study consisted of 713 middle-aged and aged couple living in Korea. Statistics employed for the analysis were frequencies, means, x2 test, logit analysis and multiple regression. The results could be summarized as follows. The middle-aged and aged couple were planning to live independently in their elderly life. The husband's age, religion, living area, total income, total asset, home owenership had significant effects on the living arrangement of the middle-aged and aged. They had a plan to live in single detached house in their elderly life. And husband's age, educational attaintment, job, and living region were affecting the housing type in their elder life. The middle-aged and aged people had a economic plan that they estimated 970,000 won as living cost in their elderly life. And the factors affecting living costs were husband's educational attaintment, job, and total asset.
