퇴비부속도 검사 의무화가 3월 25일부터 시행됐다. 그간 현장에서는 퇴비부속도 검사 의무화에 대한 제대로 된 지침조차 없어 혼란이 가중되는 등 우려의 목소리가 터져나왔다. 이에 정부는 현장의 준비 상황 등을 감안해 1년간의 계도기간을 부여, 계도기간 동안 행정처분을 유예하고 적극적인 농가 이행지원을 추진하기로 결정했다. 그렇다면 축산 농가들은 1년의 기간을 벌게 된 것일까? 현장에서는 1년의 기간이 계도가 아닌 제대로 된 대책을 세워야 하는 준비기간이 돼야 한다고 지적하고 있다. 퇴비부속도 시행에 대비사항을 알아보고 현장의 애로사항을 들어봤다.

This study examines the effects of pre-employment efforts of the youth on their transition to the labor market. Labor market performance is accessed by the transitory period, the employment at workplace with more than 300 employees, and the wage level. Based on the effects of employment efforts for the first transitory period, job experience during school and preparatory period for employment would raise the likelihood of employment, but the school credit, grade in English, and the frequency of interviews, on the contrary, failed to reduce the transitory period. Employment effect varied according to educational background. In case of college graduates, vocational education and job experience during school were statistically significant variables leading them to decent jobs. On the other hand, in case of university graduates, job experience and language skills were proven to be important factors. Lastly, for the wage effect, in case of college graduates, vocational training, job experience during school, and English ability were proven to increase the wage level. However, vocational training after graduation and job experience during school decreased the wage level, but grade in English and pre-employment efforts during school increased the possibility of getting a decent, highly paid job for university graduates.

This study qualitatively examined the lives of non-tenured, secondary school teachers who are preparing for the teachers' exam. Semi-structured, face-to-face interviews were conducted with ten teachers and the data were analyzed using the consensual qualitative research method. Most of the participants had chosen a contract-based teaching position, believing that it would meet their financial needs, provide them with the satisfaction of being a teacher and, more importantly, afford practical help with their exam preparation. In practice, however, they suffered from low self-esteem and identity confusion due to discrimination by the school administrators. Ironically, this unfair treatment strengthened the participants' commitment to studying for the exam, in order to acquire a stable and secure position in school. However, they experienced a lot of study-related stress, including a lack of study hours, heavy study load, multiple life roles, physical exhaustion, the difficulties caused by the vague exam guide, and anxiety due to previous failure in the exam. Based on the findings of this study, directions for future research are suggested.

Although recent policies and regulations in Korea strongly advocate and encourage cultivation of venture foundations, studies on venture foundation and success are very limited and often primarily focus on entrepreneurship or individual quality as a venture founder in addition to such studies' validity in question. Therefore, this study primarily focuses on venture preparation process which is subject to venture founder's effort to verify the policy effectiveness in the relationship between venture preparation and business performance. Major goal of this study is to reduce social cost of venture failure by suggesting systematic policy support for venture foundations and analyzing the relationship between following variables: first, venture preparation and financial performance, second, venture preparation and non-financial performance, and third, venture preparation and business performance. 400 initial venture foundations less than 5 years are selected from KISED(Korea Institute Startup & Entrepreneurship Development) trend analysis to carry out statistical analysis using SPSS 18.0. To organize the data features, frequency analysis as well as descriptive statistics are performed to verify the hypothesis. As a result, sub-factors in measurement of venture preparation which are venture education period, venture benefit, and experience of incubating organization are selected as independent variables. Likewise, sub-factors in measurement of business performance which are financial performance and non-financial performance are used as dependent variables. To validate interactive effect, venture preparation period is selected as control variable to perform hierarchical regression analysis. The analysis result verifies that venture benefit has positive influence on financial and non-financial performance while venture education period has positive influence on non-financial influence and experience of incubating organization has negative influence on non-financial performance without influence on financial performance. In addition, interaction of venture preparation period has positive influence solely between venture benefit and non-financial performance. Through this study, appropriate supporting plans depending on the level of venture preparation can be derived to improve business performance of initial venture foundations for policy designer of venture support, and quality rather than quality improvement of venture businesses is possible through investigation of structural issues of individual venture businesses. Ultimately, this study suggests venture founders to determine whether to focus on venture preparation process or to start a venture business.

This study investigates the effects of the degree of preparation engaged in the related industry, and the amount of financial support program on R&D performance of technology based startup companies. This study seeks to discover the core variables that impacts most on business performance. However, it should be noted that the validity of such variables and their impacts on business performance can be contentious. The study sets hypothetical variables as following. Intensity of preparation of the startup company, amount of preparation and amount of work experience in related industry are independent variable. The amount of financial support program was selected as a moderating mediating variable. According to the results, the intensity of preparation had a positive relationship with R&D performance, as opposed to work experience of the founder having a negative relationship on R&D performance. The amount of support program had no significant relationship with R&D performance. Furthermore, there are negative modified effect between the amount of support program and work experience. And, there is no relationship modified effect between support program and work experience. Existing policies tend to lean heavily toward young entrepreneurs through support and guidance. The government has placed great emphasis on policies that aim to promote and create jobs for young individuals. The results suggest that the government should review their policies toward young technological entrepreneurs and that these entrepreneurs should prepare thoroughly before launching any startups.

본 논문에서는 다목적 위성 2호의 주 탑재체인 MSC (Multi-Spectral Camera)의 영상자료 검보정을 위한 검보정 target 준비 작업에 대해 설명한다. MSC 영상 자료에 대한 검보정 작업은 다목적 위성 2호의 발사 후 초기 운영 기간 (LEOP: Launch and Early Operation Phase)인 3개월 동안 수행될 예정이다. 위성 발사 전까지 MSC 영상 자료에 대한 검보정을 수행하기 위해 필요한 준비 작업들이 현재 한국항공우주연구원에서 진행중이다. LEOP 기간 동안 MSC 영상 자료를 검보정하기 위해서, MSC의 센서 특성에 따라 7가지 정도의 검보정 target에 대한 설계 초안이 완성되었으며, 향후 target에 대한 설계를 완성한 후에 2004년 중에 한 두 부지에 몇 가지 target들을 건설하고, 다목적 위성 2호의 궤도 특성을 고려하여 일부 target은 운반이 가능하도록 제작할 예정이다. 검보정 target이 촬영된 MSC 영상 자료의 분석을 통해, GSD (Ground Sample Distance), Aliasing, Linearity, Edge Slope & Response, MTF (Modulation Transfer Function), FOV & IFOV, Absolute radiometric validation, Position Accuracy 등의 MSC 검보정 요소 값들을 측정할 계획이다.
