Studying on the history of korean ancient poetry, we come in contact with a series of verses which 'Jejisarim's Kangho Shijo'. In the 16th century are the representative works among them. Sarim were involved in the domestic discords so that they brought about severe party strifes after all. 'Jejisarim's Kangho Shijo' profoundly dealt with the various problems concerning nature and human beings. Lee, Hyunbo and Lee, Whang are closely related with the philosophical attitudes of Confucianism. After this, Kyun, Homun and Jang, Kyungse can be largely summarized as the dual theory of reason and spirit. From the standpoint of natural principles, the epistmology of Confucianism. the theory of reason has characterized by ideality and reality. It can be said that the problem of harmonizing and uniting nature with human beings was solved in the unity of space and man. 'Jejisarim's Kangho Shijo' in the 16th century prominently express not only the courses of character cultivation but also the pride and close relationship between nature and human beings. We can say that 'Jejisarim's Kangho Shijo' in the 16th century are divided into both types of the conservative idealism and the reformative realism in the Jejisarim. Kangho Ship. the epistmology of Confucianism nature and human beings. ideality and reality political status and that such ships can be separated into types ideality and reality in the philosophical context.

오늘날과 같이 점점 더 치열해지는 무한 경쟁 환경에서 브랜드자산은 동원참치와 같이 시장을 개척하고 현재 시장을 선도하고 있는 기업에게 무엇보다 중요하게 관리되어야 할 대상이다. 해마다 수많은 유사 제품들이 시장에 쏟아져 나오는 상황에서 브랜드자산을 소홀히 관리하는 기업은 소비자와 투자자의 관심에서 멀어지게 되고, 후발주자들에게 추월당해 시장에서 선두자리를 빼앗기게 되는 것은 순간이기 때문이다. 1982년 대한민국에서 '참치캔'이라는 새로운 제품을 출시하는 것에서부터 3차에 걸친 경쟁업체와의 치열한 경쟁에서 시장선도자의 위치를 확고히 고수한 동원참치의 사례에서도 알 수 있듯이, 효과적인 브랜드관리를 통한 시장차별화 전략은 시장선도자의 위치를 사수하는 데 있어 큰 도움이 될 수 있다. 본 사례연구에서는 동원참치가 신제품 출시부터 현재의 성숙기 시장에 이르기까지 자사의 브랜드를 어떻게 관리해 왔으며, 이와 연관해 어떠한 차별화전략을 구사하여 변함없이 시장선도자의 위치를 고수하게 되었는지를 살펴본다. 동원참치의 효과적인 브랜드 관리를 통한 시장차별화 사례는 여타 기업들에게 브랜드관리에 대한 지침을 줄 수 있을 것이다.

As a means of improving Korean Soil Classification System, we have reviewed Australian Soil Classification System by comparing Soil Taxonomy and FAO/WRB Classification System. Australian Soil Classification System is composed of 14 of Order, 87 of Sub-order, 556 of Great-group, 2,451 of Sub-group, and 7,276 of Family. Interestingly, soil order has the Anthroposols which is not classified with Soil Taxonomy, and the classification for some of soils is based on soil texture abruption horizon and soil structure. Seven of 14 soil orders are classified with an old version based on soil color rather than morphological characteristics. The distribution scale of Australian soil order is the largest in Tenosols, and followed by Kandosols, Rudosols, Sodosols and Vertisols in Australia.

This study discussed how the Moo-hyup prototype that has been formed from novels and comics was applied to TV drama in modern form beyond martial art movies, historical TV series and games by exploring Japanese TV drama . This study showed that follows the Moo-hyup prototype such as imaginary space and violence, the relationship between characters with the spirit of Moo-hyup, and the structure of Moo-hyup story rather than a story of teenagers' growing-up. This study is ultimately expected to reveal the possibility that the Moohyup prototype can be applied to the TV drama in modern form as well as historical stories.

The study was performed to determine effective soil depth with crop type. Lysimeters, filled with three types of soils (sandy loam, loam and clay loam), were used. Effective soil depths for 25 cm, 50 cm, 75 cm, and 100 cm were considered for each soil. Six crops were investigated for plant height and yield, and rooting depths: Chinese cabbage, maize, lettuce, potato, red pepper, and soybean. Experiment was conducted at the National Institute of Agricultural Sciences in Suwon from 2012 to 2014. Effective rooting depth including 70% of root ranged from 19 cm to 29 cm for Chinese cabbage, from 24 cm to 38 cm for maize, from 17 cm to 24 cm for lettuce, from 27 cm to 32 cm for soybean, and around 50 cm and 30 cm for potato and red pepper. The maximum depth was 60 cm for soybean, 50 cm for Chinese cabbage, lettuce, and potato, and 75 cm for maize and red pepper. Each crop showed high yield in the treatment with soil depth over maximum rooting depth under all soils.

Under concentrated illuminations, the solar cells show higher efficiencies mainly due to an increase of the open circuit voltage. In this study, InGaP/InGaAs/Ge triple-junction solar cells have been grown by a low pressure metalorganic chemical vapor deposition. Photovoltaic characteristics of the fabricated solar cells are investigated with a class A solar simulator under concentrated illuminations from 1 to 100 suns. Ideally, the open circuit voltage should increase with the current level when maintained at the same temperature. However, the fabricated solar cells show degraded open circuit voltages under high concentrations around 100 suns. This means that the heat sink design is not optimized to keep the cell temperature at $25^{\circ}C$. To demonstrate the thermal degradation, changes of the device performance are investigated with different bonding conditions and heat sink materials.

The monolithic weighing lysimeter is a useful facility that could directly measure water movement via layers, drainage, and evapotranspiration (ET) with precise sensors. We evaluated water movement through layers and water balance using the lysimeter with undisturbed paddy sandy loam soil, Gangseo soil series (mesic family of Anthraquic Eutrudepts classified by Soil Taxonomy) during winter season from Dec. 2014 to Feb. 2015. Daily ET indicated up to 1.5 mm in December and January and 2 mm in February. The abrupt increase of soil water tension at the depth of 0.1 m, when soil temperature at the same depth was below $2^{\circ}C$, was observed due to temporary frost heaving. The surface evaporation was less than reference ET below -15 kPa of soil water potential at the depth of 0.1 m. The maximum drainage rate was similar to the saturated hydraulic conductivity of a plow pan layer. Both upward and downward water movement, related to ET and drainage, were retarded by a plow pan layer. This study demonstrated that the lysimeter study could well quantify water balance components even under frost heaving during winter season and that a plow pan with low permeability could act as a boundary that affects drainage and evapotranspiration.

This experiment was conducted in Suwon and Iksan city from 2012 to 2014 to evaluate soil erosion and nutrient loss from irrigated paddy fields during cropping period. Rainfall amount and rainfall erosivity of $EI_{30}$ were, on average, 1,026 mm and $3,922mm\;ha^{-1}yr^{-1}hr^{-1}$ for the cropping period, respectively, and the rainfall event with maximum $EI_{30}$ occurred in July. Annual average of runoff was $2,508MT\;ha^{-1}yr^{-1}$ in Suwon and $3,375MT\;ha^{-1}yr^{-1}$ in Iksan, accounting for 36% of rainfall of the cropping period. Nutrient loss by runoff, on average, was $7.0kg\;N\;ha^{-1}yr^{-1}$, $1.3kg\;P\;ha^{-1}yr^{-1}$, and $16.6kg\;K\;ha^{-1}yr^{-1}$; N, P, and K loss were 5.0, 0.6, and $8.3kg\;ha^{-1}yr^{-1}$, respectively, in Suwon and 8.9, 1.9, and $16.7kg\;ha^{-1}yr^{-1}$ in Iksan. Soil loss in Korean paddy rice was evaluated as $0.33MT\;ha^{-1}yr^{-1}$ ranging from $0.05MT\;ha^{-1}yr^{-1}$ to $0.88MT\;ha^{-1}yr^{-1}$. Amount of soil loss, however, depended on areas and year influenced by variation of rainfall amount and intensity. Interestingly, soil erosion in Iksan in 2012 was remarkably greater than those in other periods due to heavy rainfall between late May and June with soil flake dispersion right after the rice-planting season.
