This study investigates the current status of the green growth policies of Korean public corporations and proposes some potential improvement ideas. A set of twenty global green trends are first elicited by using classified macro trends of environmental changes. The green trends are categorized into four key issues based on which domestic and international research efforts are compared. The management performance reports of Korean public corporations are then throughly analyzed to evaluate the validity of their strategic green tasks in relevant to the global green trends. Finally, we suggest some potential government policies for enhancing the existing green growth businesses of public corporations.

Home meal replacements (HMR) are kinds of convenient foods as cooked or semi-cooked foods, which are produced outside of home, to eat directly or after simple cooking in substitution for traditional home meals. Recently the market size for HMR is expanding rapidly around the world due to the changes of global consumer trends, growth of single-person household, increase in economic participation of women, aging population, and so on. The Europe takes over 52.4% of the global market share for HMR in global HMR market, and North America, Asia-Pacific, and Africa-Middle East are following. The most popular HMR products in US and Europe are frozen foods, whereas the market share of chilled products in Asia including Japan, South Korea, and Vietnam are much higher than that in US and Europe. Currently, the trends in HMR is focus on the expansion of the list of products that replace for meals with simple cooking, but it is expected that nutrition-enforced HMR product for aged persons or patients who live alone are requested for the further growth of the HMR market.

우리나라의 대표적인 황폐된 임지의 인공복원 성공지인 영일사방사업지를 대상으로 산림식생의 구성적 특성과 천이경향이 총 68개 조사구를 토대로 식물사회학적 방법과 매목조사법에 의하여 연구되었으며, 주요 사방조림목의 생장패턴이 연륜심 분석을 통하여 파악되었다. 이 지역의 식생형은 싸리-억새형과 사방오리-때죽나무형 등 2개 광역그룹으로 대별되었으며, 9개의 하위 식생단위가 유형화되었다. 상재도 패턴은 고상재도종(${\geq}IV$)은 2.6%에 불과하고 대부분의 종들이 저상재도종으로 생육분포하고 있었다. 식생천이경향은 대부분이 졸참나무림으로 변화될 것으로 판단되었다. 주요 사방조림목의 연평균 생장 폭은 수종별로 다소 차이가 있지만 곰솔과 리기다소나무 등 침엽수는 3.0~3.4 mm, 사방오리, 아까시나무, 물오리나무 등 활엽수는 4.3~4.9 mm로 나타났으며, 생장패턴은 수종에 관계없이 조림후 20~25년이 지나면서 급격한 생장감소를 보이고 있음을 알 수 있었다.

The purpose of this study was to analyze the breast growth variation trends and characteristics of Korean adolescent girls based on 3D body measurements. Subjects were 174 girls aged between 13 and 18. 3D body scanning data were collected and the data were measured by Geomagic Design X program. The total of 18 anthropometric measurements and 4 index items were analyzed. The main results of this study are as follows: 1) Overall, the breast growth of adolescent girls got out of children's body shapes at the age of 14 and the adult's body shapes appeared remarkably at the age of 18. Before the age of 15, the adolescent girls' breast enlarged. 2) The surface lengths of upper body, which means the breast volume, showed significant growth above B cup groups rather than under A cup groups. The demand of B cup size (32.2%) was higher than A cup size (25.9%). And 35.6% of subjects' brassiere band size was 70. 3) The thorax grew evenly in the circumference, depth and breadth. The thoracic development related to the breast volume as well as the whole upper body's development. These results reveal that it is necessary to develop adolescent girls' brassiere reflecting on adolescent girls' breast growth variation trends and characteristics by age, breast size and thoracic development.

In this paper, we review the technical trends of diamond and gallium oxide ($Ga_2O_3$) semiconductor technologies among ultra-wide bandgap semiconductor technologies for harsh environments. Diamond exhibits some of the most extreme physical properties such as a wide bandgap, high breakdown field, high electron mobility, and high thermal conductivity, yet its practical use in harsh environments has been limited owing to its scarcity, expense, and small-sized substrate. In addition, the difficulty of n-type doping through ion implantation into diamond is an obstacle to the normally-off operation of transistors. $Ga_2O_3$ also has material properties such as a wide bandgap, high breakdown field, and high working temperature superior to that of silicon, gallium arsenide, gallium nitride, silicon carbide, and so on. In addition, $Ga_2O_3$ bulk crystal growth has developed dramatically. Although the bulk growth is still relatively immature, a 2-inch substrate can already be purchased, whereas 4- and 6-inch substrates are currently under development. Owing to the rapid development of $Ga_2O_3$ bulk and epitaxy growth, device results have quickly followed. We look briefly into diamond and $Ga_2O_3$ semiconductor devices and epitaxy results that can be applied to harsh environments.

To identify the long-term influence of acid rain treatment on tree growth, acid rain of various composition (pH 2.0, pH 4.0 and pH 5.6 as control) was applied to several landscape trees for five months (April through August, 1991). Tree height, pH values and $Al^{3+}$ concentration in soil were investigated. Acid rain treatments seemed to promote height growth in the first year (1991), but have become an inhibiting factor over five years. All of coniferous species and most broad-leaved species, except Acer ginnala, showed opposite trends in height responses to acid rain treatments between the first (1991) and last (1996) year. In contrast, Acer ginnala showed similar trends to acid rain treatments in the height growth between 1991 and 1996. This result suggested that Acer ginnala has a characteristic adapability to acid rain stress. pH values of surface soil were lower than those of 30 cm soil depth. This fact suggested that acid rain treatments made surface soil acidic condition. In addition, physiological characteristics (photosynthesis, stomatal condition and biomass) have to be investigated to identify the relationship between long-term effects of $AL^{3+}$ concentration and growth.

Recent research trends of human growth hormone (hGH) are divided into improved first-generation products, long-acting second-generation products, and biosimilar products. Among the improved first-generation products studies, studies of injection devices are being actively conducted. The long-acting second-generation products are focused on extending the half-life of hGH, and depending on the results of the clinical trials, the candidates are expected to lead the future hGH market. Finally, biosimilar has had less impact on the hGH market before now; however, expectations of low-cost products still remainas an opportunity.

Since the mid-1990s, Korea has recorded low population growth rate. Based on the figures provided by the Statistical Korea, Korea may be even confronted with decreasing trends in the total population at the end of 2010s. In addition, Korea may experience the hyper-aged society in the mid-2020s. In the depopulation era, we have to devise alternative urban management policies reflecting low and reversed trends in the urban population. It is almost certain that urban policy-makers have to deal with a new series of urban problems, even jeopardizing the continuity of urban territories. In order to minimize the negative impact derived from depopulated phenomena, they have to develop sound and sustainable urban policy alternatives. This research adopts system dynamics approaches, revealing key factors exerting significant impact on the existing urban management policies. In specific, it pays attention to major causal loops, reinforcing or balancing behavioral.
