  • Forest stand development in Kwangnung Experimental Forest, Korea, was simulated with a forest succession gap model of the JABOWA/FORET type, in order to predict climax species and characterime the trend of community structure along the succession. The model runs for a period or 1, 000 yr and is based on the averaged successional characteristics of 50 forest plote with an individual size or 1/12 ha gap consisted of the 15 major tree species. The total bimass and leafarea index have arrived at a steady state since about 200 yr and these values are smaller than that or field survey. Carpinus cordata, C. laxiflora, Quercus mongolica and Q. serrata were epected to be climax species that represent about 86% or total biomass in later stage and these results coincided with the previous succession studies from field survey in the area.

  • The purpose of this study is to present the model of ecological restoration through analysis on the condition of hydrach succession process in brackish water lake. To this study, we investigate and research the present condition of brackish water lake in South Korea. Most brackish water lake in South Korea have characteristics that is come into being malignant hydrach succession. Many lakes were reclaimed to increase foodstuff production. And river conservation work seperate lakes from the ocean. In a embryological view, most lakes based on the brackish water lakes, But present lakes show many different types such as a fresh water lake, a salt lake, a brackish water lake, a swamp, and a marshland. As a result, brackish water lakes have greatly damaged by diverse artificial interventions to promote people's activities. Therefore, in order to manage brackish water lakes systematically, criteria of lake preservation must be coincide with the present conditions of hydrach succession in each lake.

  • Exergy is defined as the amount of work (entropy-free energy) a system can perform when it is brought into thermodynamic equilibrium with its environment. Exergy measures the distance from the inorganic soup in energy terms. Therefore, exergy can be considered as fuel for any system that converts energy and matter in a metabolic process. The aim of this study is to introduce structural dynamic modelling which is based on maximum exergy principle. Especially, almost ecological models couldn't explain algal succession until now. New model (structural dynamic model) is anticipated to predict or explain the succession theory. If the new concept using maximum exergy principle is used, algal succession can be explained in many actual cases. Therefore, It is estimated that structural dynamic model using maximum exergy principle might be a excellent tool to understand succession of nature from now on.

  • This study is to find effects between the level of preparation of factors and the satisfaction of successors. Independent variables are the level of preparations of successors and divided by three detailed type, the level of preparation of management ability, the level preparation of positive succession attitude and the level of preparation of ownership succession. A dependent variable is the satisfaction of successors and a moderating variable is the level of communication between successees and successors. This study was undertaken in South Korea among 59 successors in 59 family firms. A total of 53 samples were available to use for the research. The empirical results indicate that the level of preparation of successors, management ability, positive succession attitude and ownership succession, is associated to the satisfactions of successors. Additionally, the moderating variable has not the relationship to the dependent variable as a moderating variable, but the result showed a strong relationship between the level of communication and the satisfaction of successors.

  • Forensic entomology is a field of study that includes the succession of insects attracted to and found on cadavers. One of its main focusses is estimating post-mortem interval (PMI) based on the growth stage of insects found in and around human cadavers. In many countries, the diversity of insect occurrence is studied in relation to the environmental conditions a cadaver may be exposed to or the effects of different clothes. In this study, changes in the decomposition process and differences in insect succession were investigated by comparing skinned and intact water deer carcasses. Five orders, 15 families, and 21 species of insects were identified, most of which were Dipteran and Coleopteran. The skinned carcass decomposed more rapidly than the intact carcass, which was linked to differences in insect succession. The difference in the decomposition rate and insect succession according to the external conditions of the carcass can be used as basic data for estimating the PMI of the carcass and setting the forensic entomological indicator species.

  • Family businesses play a significant role in the overall economy of all countries, and the importance and weight of family businesses are increasing in various fields. Many factors are essential for a family business to grow into a long-lived business, that is, a sustainable business, but the most important one is succession. TRUST Lab at Hanyang University studied the importance of factors influencing the succession of the family business from the standpoint of the successor. As a result, it was confirmed that mutual trust is the most crucial factor, and conflict can destroy that trust. Therefore, in this study, we research conflict as a central topic for successful succession, which is the most fundamental reason for family businesses. This study was conducted as a qualitative research case study. By setting criteria suitable for the purpose of the study, we conducted interviews with ten successors who either worked or planned to work in a family-related company. Through this study, conflict management of key players is the most important to achieve a continuous succession of family businesses.

  • 우리 민법에 상속인이 민법 제1019조 제1항의 기간 내에 한정승인 또는 포기를 하지 아니한 때에는 단순승인을 한 것으로 본다고 하여 그동안 상속인들에게 지나치게 불리하다는 비판을 받아왔던 규정이 1998년 8월 27일 선고된 헌법재판소 결정(96헌가 22 등)에 의하여 헌법불합치결정을 받았다. 이에 따라 2002년 1월 14일 법률 제6591호로 공포 시행된 개정민법 제1019조 제3항으로 "민법 제1019조 제1항의 규정에 불구하고 상속인은 상속채무가 상속재산을 초과하는 사실을 중대한 과실 없이 제1항의 기간 내에 알지 못하고 단순승인을 한 경우에는 그 사실을 안 날부터 3월내에 한정승인을 할 수 있다."는 규정이 신설되었다. 그러나 민법 제1019조 제3항은 상속인들에게 구제의 길이 열리기는 하였으나 상속인의 보호가 제한적이고 상속인에게 한정승인만을 허용하고 상속포기의 선택을 제한하여 상속인의 승인 포기의 선택권행사에 문제가 있다고 본다. 따라서 이 논문에서는 상속의 승인과 포기에 관한 문제점을 검토해보고 상속인과 이해당사자들 간 모두에게 불리함이 없이 가장 공평하고 합리적인 개선방안을 제시하고자 한다.

  • This study was carried out in order to analyze the succession characteristics of the slope of expressways and the results of analysis by collecting and analyzing various literatures and data from 2011 to 2012 and surveying 75 expressway slope, as follows : The construction methods applied to planting the slope of an expressway can be classified into 4 types including 3 Climber planting methods, 8 Vegetation thick-layer spray work methods, 4 Seed spray work methods, and 4 Stabilization work methods. The factors which affect the cover degree of the slope of an expressway were found to be development years, gradient, length, and azimuth. Like surrounding forest areas, the expressway slope was analyzed to begin the plant succession 20, 30, and 40 years after development, and plant succession was developed in diversity in a mixed stand forest according to surrounding forest floors. Species diversity, maximum species diversity, and the evenness of slope facing north were analyzed to be high comparing to those facing east, west, and south according to azimuth of slope. Species diversity, maximum species diversity, evenness of slope, and the plant succession of surroundings were analyzed to be high when the gradient of the slope was less than $40^{\circ}$. The dominant species which success on the slope of an expressway and its surrounding forest area included Miscanthus sinensis var. purpurascens, Zoysia japonica, Pinus thunbergii Parl, Rubus crataegifolius, Lespedeza cyrtobotrya, Amorpha fruticosa, Artemisia princeps var. orientalis, and Oenothera biennis.

  • This study identified the effects of history length and brand legitimacy succession on Brand Historicity (BH) in Fashion Brand Stories and Brand Attitude (BA) with Consumer Orientation (CO). The study conducted an experiment where participants were surveyed after reading a manipulated brand story composed of 2 kinds of brand historicity, brand establishment year (150 years, 70 years, and 20 years) and legitimacy succession (legitimacy succession and legitimacy handover). The results are as follow. First, the sub-dimensions of Brand Historicity appeared to be brand uniqueness, traditionality, symbolism, and managerial traits. Second, brand legitimacy succession types influenced the perceptions of BH with CO. Third, brand legitimacy succession types influenced the perceptions of BA1 (rational brand attitude) and BH1 (brand uniqueness), BH2 (brand traditionality) with CO, which were BA's sub-dimension. Forth, the consumer orientations that influenced BH and BA appeared to be nostalgia orientation, conspicuous consumption orientation, and fashion orientation; however, uniqueness pursuit orientations influenced only BH.
