1997년 외환위기 이후 우리나라의 정부부채는 급속히 증가하여 왔다. 일반적으로 재정적자 및 정부부채의 증가는 여러 가지 거시경제적 부작용을 초래할 것으로 예상된다. 본 연구의 목적은 그중에서 특히 재정악화의 결과 물가상승이 유발될 가능성을 실증적으로 살펴보는 것이다. 정부의 예산제약을 고려하면 재정악화는 궁극적으로 미래의 재정수지 흑자나 물가상승을 통하여 해소될 수 밖에 없다. 재정주의적 물가결정이론은 바로 이러한 점에 착안하여 재정이 물가의 결정에 대항 중요한 역할을 할 수 있음을 강조한다. 즉, 미래의 정부기초수지에 대한 예상이 일정하다면 물가는 궁극적으로 통화가 아니라 재정에 의하여 결정된다는 것이다. 그러나 반대로 미래의 통화정책에 대한 예상이 일정하다면 현재의 재정적자는 미래의 재정흑자를 유발할 뿐이며 물가에는 영향을 미치지 못할 것이다. 따라서 실제로 재정악화가 얼마나 물가상승을 유발할 것인가는 실증적으로 결정될 수밖에 없다. 기존의 OECD 국가들에 대한 실증분석에 의하면 재정수지는 통화량이나 물가에 대하여 뚜렷한 영향을 미치지 않는 것으로 나타난다. 그러나 기존의 실증분석들은 대부분 미래의 재정수지에 대한 예상을 제대로 고려하지 않고 있으므로, 이러한 결과가 재정주의적 물가결정이론에 대한 정확한 검정을 제공하는 것이라고 볼 수는 없다. 본 연구에서는 이러한 문제의식하에 선진국과 개도국의 자료를 이용하여 재정주의적 물가결정이론의 타당성을 재검토해보고자 한다. 먼저 선진국에 대해서는 VAR모형의 충격반응(Impules Response)을 이용하여 재정수지에 대한 예상을 직접 고려함으로써 앞서 설명한 편차의 가능성을 줄일 수 있을 것으로 예상된다. 한편 개도국의 경우에는 일반적으로 재정규율이 낮을 것으로 예상되므로 미래의 재정수지에 대한 명시적인 고려가 없이도 재정적자 및 정부부채의 확대가 물가 및 통화량에 미치는 관계가 비교적 용이하게 관찰될 수 있을 것으로 예상할 수 있다. 본 연구의 실증결과에 의하면, 먼저 비교적 재정규율이 강할 것으로 예상되는 OECD 국가들에서는 기존의 실증분석결과와 마찬가지로 정부부채의 증가가 주로 그 이후의 기초수지의 개선을 통하여 보전되며 물가에는 큰 영향을 미치지 않는 것으로 나타난다. 그러나 OECD 국가들 가운데에서도 재정규율이 비교적 약한 나라들에서는 부채 증가 후 기초수지에 뚜렷한 변화가 관찰되지 않으며 따라서 물가가 상승하는 것으로 나타난다. 또한 재정규율이 일반적으로 약한 개도국들에서는 예상대로 부채수준이 높은 국가일수록 물가상승률이 높게 나타난다. 특히 개도국에서 GDP 대비 정부부채가 10%포인트 증가할 경우 물가상승률은 장기적으로 약 1.5~2%포인트 확대되는 것으로 추정된다. 이러한 결과는 정부부채에 일정한 상한이 존재함을 시사하는 것으로서, 대체로 재정주의적 견해와 일치하는 것으로 판단된다. 따라서 우리나라에서도 만일 정부부채의 증가추세가 지속된다면 결국은 일반 국민의 조세부담이 증가하거나 아니면 물가상승이 유발될 수밖에 없을 것이다.

Due to the influence of the fourth industrial revolution in recent years, maker education is getting attention. Therefore, this study tried to propose the possibility of application (app) development education as maker education by empirically verifying the affective and cognitive effects of app development education using authoring tool. To do this, we implemented app development education in D high school in Seoul, Korea, and collected data from 41 participants. We analyzed the changes in attitudes toward SW education and creative problem-solving ability before and after the education by conducting the paired t-test, and the level of satisfaction and perceived achievement through descriptive statistics analysis. Also, the learner's responses collected through the open-ended questionnaire were analyzed qualitatively. The result showed that the attitude toward SW education and creative problem-solving ability showed statistically significant improvement after app development education using the authoring tool, and the learner's statement also supported this result. Also, satisfaction and perceived achievement after the education were relatively high. Through these results, we have empirically confirmed the effect of app development education using the authoring tool for high school students, and derived the theoretical and practical implications.

This study aims to investigate the possibility of elementary students' generalization from three-digit numbers to multi-digit numbers in principles for addition and subtraction. One of main changes was the reduction of range of numbers for addition and subtraction from four-digit to three-digit. It was hypothesized that the students could generalize the principles of addition and subtraction after learning the three-digit addition and subtraction. To achieve the purpose of this study, we selected two groups as a sampling. One is called 'group 2015' who learned four-digit addition and subtraction and the other is called 'group 2016' who learned addition and subtraction only to three-digit. Because of the particularity of these subjects, this study covered two years 2015~2016. We applied our addition and subtraction test which contains ten three-digit or four-digit addition and subtraction items, respectively. We collected their results of the test and analyzed their differences using t-test. The results showed statistically meaningful difference between the mean score of the two groups only for four-digit subtraction. Based on the result, we discussed and made some didactical suggestions for teaching multi-digit addition and subtraction.

While the cost of technology development is increased, the life cycle of products and services that have been developed has become progressively shorter. Open innovation have been increasing by company as a strategy to respond to the rapidly changed market. Technology transfer from universities is one of the typical means of technological innovation. Although a university has invested significant resources in R&D, the results has been neglected. Therefore, at the moment, research is needed about the outcomes and efficiency of technology transfer at universities. In the previous research, since most of studies focus on the analysis of factors that influence the outcome of technology transfer, in this study, targeting domestic universities, the efficiency of technology transfer at the university was analyzed. In addition, differences in the efficiency of different types of university is verified. Consequently, universities specializing in technology and industry has high-efficiency than the others. There is no significant difference between the groups of universities whether or not to participate in Technology Licensing Office(TLO). More efforts are required for successful results of TLO in Korea. This study is expected to be able to provide reasonable indicators on technology transfer for further research.

Line density index(LDI) was developed to quantify a densely isothermal line rate as standard index in the ocean environment. Theoretical background on the LDI development process restricting index range 0 to 100 was described. And validation test was done for the LDI application condition that total line length is not greater than 1/10 of unit area. NOAA SST(Sea Surface Temperature) data were used for the experimental application of LDI in the South Sea of Korea. Using GIS, $0.1^{\circ}C$ isothermal lines were linearized as vector data form SST raster data, and unit area were built as polygon data. For the LDI calculation, spatial overlapping(line in polygon) was implemented. To analyze the effect of unit area size for the LDI distribution, two cases of unit area size were designed and descriptive statistics was calculated including performing normality test. The results showed no change of LDI's essential characteristics such as mean and normality except for the range of value, variance and standard deviation. Accordingly, it was found that complex structure of thermal front and even smaller scale of front width than unit area size could influence on the LDI distribution. Also, correlation analysis performed between LDI and difference of temperature(${\Delta}T^{\circ}C$), and horizontal thermal gradient(${\Delta}T^{\circ}C/km$) on the front was obtained from linear regression model. This obtained value was compared with the results from previous researches. Newly developed LDI can be used to compare the thermal front regions changing spatio-temporally in the ocean environment using absolute index value. It is considered to be significant to analyze the relationship between thermal front and marine environment or front and marine organisms in a quantitative approach described in this study.

The purpose of this study was to develop a practical reasoning model for the 'parenthood' part of the 'marriage and child rearing' unit of high school first-grade technology & home economics based on the instruction objectives selected from 11 different kinds of textbooks, and to examine the effects of the model. Learning objectives and contents were selected, and a practical reasoning teaching model of six sessions was developed and implemented in class. The subjects in this study were students in five first-year classes in a high school located in the city of Icheon, Gyeonggi province. The effectiveness of the model was analyzed by conducting a survey on the students before and after its application. Assessments were also conducted on the lessons applied. Students who received instruction according to the practical reasoning model underwent a significant change, as they displayed higher scores in understanding the meaning of parenthood, preparation for parenthood, and the role of parenting. As a result of applying the model, it was found that the classes proved to be helpful to the students.

The purpose of this study was to determine the possibility of character education in the middle school home economics program: by extracting learning factors that can cultivate gratitude disposition from the eighth grade in the unit of 'clothing life' of middle school HE text, developing five teaching-learning lesson plans and learning materials, and applying them in classrooms to see any changes in gratitude disposition standards before and after its application. Five teaching-learning lesson plans for the cultivation of gratitude disposition were developed, and completed after three experts in home economics verified their validity and revised them. From June 1, 2010 to June 30, 2010, five classes were to 210 grade students at a Gyeongbuk Junior School, and dispositions were investigated before and after the classes. Gratitude disposition standards used GQ-6, like McCullough, and for before-and-after-inspection comparison, t-test and analysis of open-ended questionnaires were carried out. The results proved the instruction effective. Before the class for the cultivation of gratitude disposition, students had a gratitude disposition average of 2.87(out of 5). After the class, the average was 3.35, which shows that students had improved considerably. Also, in analysis of a open-ended questionnaire, it was said that the class had been provided the opportunity to think about the value of nature and neighbors and that the class content reminded them about appreciation. In conclusion, for the character education in other areas of middle school home economics, teaching-learning lesson plans development must be attained to further this character education program.

This study investigates the question of how political and economic factors may affect the export of renewable energy technologies. The relationships are tested using panel data for 19 OECD member countries over the period 1992-2012. Before establishing the empirical model, the current study checks the characteristics of the panel data, which includes various panel framework analyses, such as tests for the presence of normality, structural breaks, first-order autocorrelation, heteroscedasticity, cross-sectional dependence, panel unit-root. From the panel framework analyses, a dynamic panel model is established to test the relationship between the variables examined in this study. In order to reduce the bias of the estimation of the dynamic panel model and obtain efficient parameters, this study uses the bias-corrected least square dummy variable(LSDVC) estimator to estimate the empirical model. The results of this study show that governmental policies expressed as coercive pressure and market size positively affect the export growth of renewable energy technologies. However, public pressure and traditional energy industry have no significant effects on export performance. Policy implications are presented based on the results of this study.

In order to successfully adopt and implement the Balanced Scorecard(BSC), firms need to respond adequately to the rapid changes of today's business environment and consider the growing importance of non financial factors in the business activities such as intangible assets(R&D expenditure, patent, goodwill, etc.). Our primary focus throughout this paper is on developing Key Performance Index(KPI) of BSC for R&D expenditure activities. In this study, we have developed and named PEI(Patent Efficiency Index),which is the KPI for R&D expenditure by focusing on the efficiency of a patent that is the output from the R&D expenditures. Secondarily, we have attempted to address the solution for the current problems of the traditional R&D performance measurement by using our developed PEI and examine the usefulness and effectiveness of the newly developed our PEI. According to the empirical test results, we find that the PEI is positively associated with ROA and Tobin's Q, respectively and show that our developed PEI is more effective and accurate than the traditional R&D performance measurement as a business performance measurement. Furthermore, these findings proves that we can measure and evaluate how efficiently the firms perform the R&D activities and shows that the PEI can be a critical index for evaluating firm's business performance related to the R&D expenditures.
