This study investigated the public use of Myeon Location in Jeollanam - do where the population is at risk of declining. And discussed the rational provision and coordination of public facilities as a guarantee of fundamental rights. As a result of the study, the rational supply and adjustment directions of public facilities are as follows. First, there are problems such as high availability of management, finance, shopping, and health facilities, lack of culture, leisure, community facilities, and weakening of center function. Therefore, in the continuing declining population situation, face management, safety and health facilities should be upgraded to multifunctional facilities, and utilization efficiency and integration should be promoted. In addition, town center rehabilitation should be centered on multifunctional facilities. In addition, elementary schools will have to utilize and preserve them to take advantage of local cultural values as nostalgia storing place that provide incentives for young people and elementary school children in the future. Second, in order to cope with population decline, public facilities need to strengthen public services through complexity and multifunctionality, wide-area operation with neighboring areas, and user-centered operation management.

The purpose of this study is to present a rational depreciation method for a pyroprocess cost calculation. Toward this end, the so-called advanced decelerated depreciation method (ADDM) was developed that complements the limitations of the existing depreciation methods such as the straight-line method and fixed percentage of declining-balance method. ADDM was used to show the trend of the direct material cost and direct labor cost compared to the straight-line or fixed percentage of the declining-balance methods that are often used today. As a result, it was demonstrated that the depreciation cost of the ADDM, which assumed a pyroprocess facility's life period to be 40 years with a deceleration rate of 5%, takes up 4.14% and 27.74% of the pyroprocess unit cost ($781/kg heavy metal) in the $1^{st}$ and final years, respectively. In other words, it was found that the ADDM can cost the pyroprocess facility's capital investment rationally every year. Finally, ADDM's validity was verified by confirming that the sum of the depreciation cost by year, and the sum of the purchasing cost of the building and equipment, are the same.

본 연구는 전나무림 생태계 이해를 위하여 전나무 임분구조에 관한 기초자료를 수집하는 조사의 일부이다. Leibundgut(1981)의 임분구조 분류에 따르면 A,B임분은 쇠퇴기로 추정되며 C는 갱신기, D는 안정기와 쇠퇴기 복합형, E는 불안정한 시기인 택벌상으로 추정된다.

Multistage deformation behavior of Nb-microalloyed steel and carbon steel was studied by torsion test with declining temperature T, constant pass strain $\varepsilon_i$, interrupt time $(t_i)$, and varying strain rate $(\.{\varepsilon})$. In the range of $1000^{\circ}C~790^{\circ}C$ and 4.00/sec~0.38/sec, the flow stress at each pass was correlated to the deformation variables. As the finished deformation temperatures are decreased to the range of $790^{\circ}C~900^{\circ}C$, Nb precipitates play an important role on the grain refinement of Nb-microalloyed steel. the flow stress of Nb-microalloyed steel was higher than the carbon steel's while the grain size of Nb-microalloyed steel was smaller than carbon steel below the temperature of $900^{\circ}C$.

This paper describes a tracking test results for the organic polymers with PE(polyethylene) series by a declining method. After processing the 4 PE series insulations with different density, the tracking duration for each was measured and compared with that for ABS(acrylonitrile butadiene styrene). The surface condition of each specimen was carefully observed after the tracking test. As a result, HDPE showed excellent performance in tracking test.

In the race for establishing trading architecture consistent with new landscape of the global economy, the US is ahead of the game by concluding the Trans Pacific Partnership Agreement with 11 countries. To make it reality, the ratification is essential. In the battle for ratification in the US, declining globalism confronts rising protectionism. This paper models the ratification process as contest between globalism and protectionism, and analyzes the optimal timing for ratification. Based on this framework, various ratification scenarios are analyzed. The paper argues less likelihood for the lame-duck session passage and more likelihood for prolonged and protracted delay, due to changing political dynamics and declining intellectual support for globalism. Hence, the future of Trans Pacific Partnership Agreement may prove different, compared to the North American Free Trade Agreement and the Korea-US Free Trade Agreement, both of which were renegotiated and ratified eventually. Then, the US would lose the first move advantage. The paper also discusses strategic implications of delayed ratification on the evolution of trading architecture in East Asia.

해상 가두리 양식장은 수중 내 암모니아성 질소 배설물을 제거 할 수 있는 것이 불가능하다. 암모니아성 질소를 효과적으로 제거하지 못하여 대량 폐사를 하거나 섭이 활동을 저하 시키는 원인이 된다. 또한 공급된 사료를 어류들의 섭이 활동 저하로 낭비 되는 것이 현실이다. 이러한 문제점을 해결하기 위하여 해상 가두리 양식장의 환경 요인 중에 암모니아를 원격에서 자동으로 측정하고 감시 할 수 있는 장치를 구성 하고자 한다.

In this study, the 3- dimensional (3-D) learning contents are suggested using 'Augmented Reality' instead of existing 2-dimensional (2-D) learning methods. At the present, there are some 2-D learning methods using texts, image, pictures, and videos called e-learning. However, these one-way 2-D methods have some disadvantages such as declining learner's immersion and concentration. Thus, the 3-D learning contents using 'Augmented Reality' are suggested to compensate the disadvantages. According to the development of information technology (IT), the augmented reality has many applications to the era of ubiquitous. However, there are some disadvantages when learners use these contents as following; non-augmenting by partially hiding from makers and declining concentration by patterns of the makers. In this study, the beneficial marker which can solve this non-augmenting phenomenon is suggested.

Purpose: This research investigates the paths of some important economic variables: government domestic product (GDP), capital accumulation, unemployment rates. Decreasing GDP, declining capital accumulation and higher unemployment affect to South Korea economy. The macroeconomic policies discussed are all capital financed accumulation policy and an enactment of unemployment regulation. Research design, data and methodology: The GDP, capital accumulation rates and unemployment rates are the main macroeconomic issues in the South Korea. This research studies the correlations of the GDP, capital accumulation, and unemployment rates by time series data from 2000 to 2005 in a Vector Autoregressive (VAR). Results: The first, GDP relates a positive effect between the GDP and capital accumulation in the long term. The second, there is the negative relationship between GDP and unemployment rates. Economic growth was strongly supported by employment growth and by declining unemployment. The third, There is positive relationship between unemployment rates and capital accumulation. Conclusions: This research provides that fiscal policy introduce to increasing GDP, private investments and employment rates. The GDP should be major on capital accumulation to increase employment rates in South Korea.
