Domestic government debt securities is one of the steps which is taken by the government of Indonesia as a major source of financial budget, covering for the budget deficit, debt payments and interest debt. The purposes of this research are to know the development of budget deficits, government debt and impact of domestic government debt securities against economic growth in Indonesia. Method of analysis used Ordinary Least Squares (OLS) analyzing the impact of the domestic debt against economic growth in Indonesia. This research uses time series data from 1997 to 2014. Total government debt and domestic government debt securities in Indonesia increased during the last five years. The average of domestic government securities was above 50 percent of the total government debt. Estimated results showed domestic government debt securities has a positive and significant effect to economic growth. Official development assistance (ODA) has a negative effect to economic growth. Other variables such as the gross fixed capital formation and receipt of remittance have positive and significant effect, total imports and government expenditure have negative and significant effect against economic growth.

We proposed a new system to collect hyperspectral data using a general cargo crane. The system has advantageous characteristics for precise data collection and analysis. In order to evaluate the validity, we performed the system on actual rice paddy field and analyzed the observed data. On the process, we could successfully extract the pure vegetation spectrum with high stability. The data taken by the system are useful for detail analysis among fields. In future development, it can be used for obtaining the grand truth for calibrating satellite or aerial hyperspectral images.

The purpose of this study is to measure the cost-benefit of a road construction project in Vietnam through international development cooperation, which includes private grants and Official Development Assistance(ODA). In developing countries, it is difficult and costly to use data on markets, the CVM(Contingent Valuation Method) to measure the WTP(Willingness-to-Pay) as the benefits of road construction are used. A total of 232 villagers in 16 villages of Lao Cai Province in Northern Vietnam have been surveyed. It is found that the Benefit-Cost Ratio(B/C) in all 3 models are found to be well over 1.0, ranging from 2.8 to 3.64 with the discount rate of 0.06. These BC ratios imply the road construction project in Lao Cai can be justified. Also, it is found that the shortened travel time is the most relevant factor for WTP among direct benefits and the enhanced academic achievement of the children is the most relevant factor among indirect benefits, due to easier and faster access to schools, which in turn increase the school attendance rate. The result of this study can be used to justify other similar projects in Vietnam, even though the benefits may have to be reassessed in other countries.

Three growing wethers were used to investigate the differences in nitrogen (N) retention, blood plasma metabolite concentration and energy-yielding nutrient supply to muscle and adipose tissue. The wethers were fed one of three diets: timothy hay with concentrate (THD), Italian ryegrass with concentrate (IRD), and rice straw with concentrate (RSD) for 11 days. The experimental diets were adjusted to the animals to provide 100 g of daily gain. The triglyceride (TG) concentration of blood plasma in arterial and portal veins was higher with THD and IRD than with RSD. Conversely, the available amount of TG in tissues was higher with IRD. The daily amount of glucose and non-esterified fatty acids (NEFA) supplied to muscle tissue and adipose tissue was numerically higher with THD than IRD or RSD. Although N retention did not differ among the diets, it was numerically higher with THD than with IRD or RSD. The results suggest that the difference in the amount of glucose and NEFA delivered to muscle tissue may reflect the N retention in response to forage based diets.

The results of examining characteristics of mycelial growth and culture condition for determining the condition of artificially culturing Fomitopsis pinicola are as follows. 1) Mycelial growth and density of F. pinicola. were the highest in the medium of PIDA(Pine Dextrose Agar;66.3mm/10d) followed by the order of GDA, PDA, CDA, PODA, ODA, YM, MCM, MEA(pH 4.7), CHA, and MEA(pH 4.7). 2) Optimal temperature for the mycelial growth and density of F. pinicola were shown to be $30^{\circ}C$, but the mycelia were dead at $40^{\circ}C$. the mycelial growth and density of KNAC9005 strains was the highest at $30^{\circ}C$(66.3mm/10d) followed by the order of 25, 20, 15, 35, 10, and $5^{\circ}C$. 3) Optimal pH for the mycelial growth and density of $40^{\circ}C$ was revealed to be 6.0(88.4mm/10d). above or below pH 6.0, the mycelial growth and density were shown to be retarded. 4) Optimal carbon, nitrogen and organic acid sources for the spawn growth of $40^{\circ}C$ were maltose(331mg/25ml/15d), peptone(347mg/25ml/15d), and glutamic acid(357mg/25ml/15d), respectively. Optimal level of biotin was 370mg/15d and optimal C/N ratio was 40.

에티오피아의 수자원은 풍부하지만 그 활용의 수준은 매우 저조하다. 그 중에서 에티오피아의 농업용수 활용 수준은 굉장히 낮게 나타난다. 에티오피아의 농업은 강우량에 의존하는 형태를 지니지만 매우 불규칙한데, 이러한 특징은 에티오피아의 충분한 농업용수 활용을 위해 관개설치로 극복하려고 한다. 여러 선행연구에서는 에티오피아의 경제적 활성화는 근본적으로 농업용수의 충분한 확보가 전제되어야 한다고 주장한다. 왜냐하면 농업용수의 확보는 농업 경제의 활성화로 나타나며, 그 활성화로 농업 생산품이 많아지고 종류가 다양화되기 때문이다. 몇몇 실증적 연구에서는 충분한 농업용수를 갖추고 있는 지역이 농업 경제가 활성화됨에 따라 소득의 증가로 귀결되었음을 증명하였다. 이러한 사실에 입각하여 에티오피아 정부는 관개를 통한 농업용수 확보에 심혈을 기울이고 있지만, 재정적 문제와 인적자본의 결여로 어려움에 봉착하고 있다. 에티오피아의 수자원 개발은 주로 국제적 지원에 의존하고 있다. 특히 World Bank를 위시한 UNICEF, 핀란드 등은 에티오피아 농촌 지역의 수자원 개발에 많은 지원을 하였다. 반면, 대부분의 국제적 지원은 도시에 집중되어 있는데, 이러한 점은 에티오피아의 도 농간 수자원 개발이 확연한 차이로 나타나게 되었다. 우리나라 역시 에티오피아의 지원에 동참하고 있다. 이러한 국제적 지원은 에티오피아에 좋은 영향을 미치지만, 수혜자의 입장을 고려하여 지원을 펼친다면 더 좋은 성과로 나타날 것이다. 실제 독일이 볼리비아의 상황을 고려하여 농촌 지역의 빈곤감소를 위한 각종 프로그램 형성 및 지원은 국제공적개발원조가 어떠한 형태로 나타나야 할 것인지에 대해 큰 시사점을 제공해준다. 독일은 볼리비아의 수자원 지역에서 자연자원 보존과 자연을 훼손하지 않는 방식의 관개를 설치하였다. 더불어 국가 정책과 연관되도록 공무원의 역량강화 프로그램을 실시하였고, 관개 교육을 통해 기술자를 양성하였다. 그 결과 농촌 지역에서는 식량 상황이 개선되었고, 소득의 증가로 귀결되었다. 이와 같이 국제원조에서는 "수원국의 필요"가 전제되어야 하고, 그 나라의 상황에 맞도록 국가 정책과 연동되어야 한다. 우리나라는 과거에 현재 에티오피아가 직면한 수자원 문제에 봉착하였었고, 이를 관개 기술의 발전으로 극복하였다. 이러한 수자원 기술을 에티오피아의 현실에 맞게 지원한다면 독일의 사례에서 살펴볼 수 있듯이 국민들의 삶의 질 향상으로 귀결될 것이다.
