In this study, to research in-cylinder flow characteristics of spark-ignited engine with intake valve closing timing change for Miller cycle. 3D simulation study were used 6 different intake valve profile with $CAD10^{\circ}$ gap for retard intake valve closing timing. Comparison of In-cylinder flow pattern characteristic were accompanied between Base and LIVC. And the efficiency of volume and the work of compression were analyzed with simulation study. When intake valve closing angle was retarded in $CAD50^{\circ}$, the pressure in cylinder was decreased about 12~13 bar and volume efficiency was reduced about 16%. The efficiency of volume and the work of compression were reduced on LIVC.

Chloride ingress is a common cause of deterioration of reinforced concrete structures. Modeling the chloride ingress is an important basis for designing reinforced concrete structures and for assessing the reliability of an existing structure. The modelling is also needed for predicting the deterioration of a reinforced structure. This paper presents an approach for the probabilistic modeling of the chloride-induced corrosion of reinforcement steel in concrete structures that takes into account the uncertainties in the physical models. The parameters of the models are modeled as random variables and the distribution of the corrosion time and probability of corrosion are determined by using Monte Carlo simulation. The predictions of the proposed model is very effective to do the decision-making about initiation time and deterioration degree.

In order to research engine characteristics of spark-ignited engine with intake valve closing timing change for Miller cycle, two cam for LIVC(Late Intake Valve Closing) were designed and fabricated an prototype valvetrain. And intake valve closing timing were adjusted to build low compressing and high expansion cycle for HEV. In experimental study, it were investigated with different engine speed, spark timing and air-fuel ratio to compare base cam and LIVC cam type. It was found that the volumetry efficiency and effective work of compression process were decreased in case of LIVC cam. When compared with the existing results, the maximum pressure in the cylinder was reduced about 12~13 bar and the volumetric efficiency was reduced about 16%.

In recently, researches which appling satellite image are introduced target to the forest area. Especially, it is satellite image analysis's advantage that collecting information of terrain at the direct accesses are dangerous and impassible area. But, the studies approaching to a inflectional paradigm of forests and change detection system for the distinguished forests type are leaves much to be desired. In this study, therefore, change of forests type was analyzed using Landsat TM satellite image which have multi-spectral bands. Furthermore, change detection system for forests type was constructed on web for the periodical monitoring.

지금까지의 투자 의사결정 요인에 관한 연구는 벤처캐피탈 관점에서 이루어져 왔다. 벤처캐피탈이 투자할 만한 가치가 있는 스타트업을 선정하는 요인이 무엇인가 하는 것이 기존의 연구의 핵심이었다. 하지만, 최근 우수한 스타트업의 경우, 많은 벤처캐피탈이 투자를 하기를 원하면서, 오히려 능력 있는 스타트업들은 벤처캐피탈을 선별해서 투자를 받고 있는 현상이 나타나고 있다. 따라서 우수한 스타트업이 벤처캐피탈을 선택하는 결정 요인을 알아봐야 하는 시기가 된 것이다. 본 연구는 창업 초기단계(Series A) 창업가 4명, 중기단계(Series B/C) 창업가 3명을 인터뷰하여 스타트업이 벤처캐피탈을 선정하는 요인을 탐색하고자 한다. 연구 결과, 스타트업이 벤처캐피탈을 선정하는 주요 요인으로는 1) 계약내용, 2) 벤처캐피탈 명성(reputation), 3) 투자 심사역인 것으로 나타났다. 먼저, 초기 및 중기 단계의 스타트업 모두가 중요하게 생각하는 요인은 계약내용으로, 구체적으로는 가치평가 (valuation)와 우호적인 투자조건으로 나타났다. 다음으로, 벤처캐피탈의 명성 (reputation)의 경우, 벤처캐피탈이 지금까지 투자해 왔던 회사들의 면면 (portfolio)과 투자한 후, 후속 투자를 하는 경향 (Follow-on)을 중요시 하는 것으로 나타났다. 마지막으로, 벤처캐피탈을 선정할 때, 창업 초기 단계에서는 상대적으로 투자심사역의 영향이 컸고, 창업 중기 단계 이후로 갈수록 투자심사역 개인보다는 회사 차원의 벤처캐피탈의 영향력이 커짐을 발견하였다.

Varied opinions have been raised on Sushen's regional activities. These are Hwabuk drift theory, Shandong Peninsula drift theory, Liaotung Peninsula theory and the theory of Eastern Area in Heilongjiang Province. The theory of Sushen Dongbei that Sushen's regional activities are the Eastern Area in Heilongjiang Province is widely accepted in the chinese academia. However, this paper try to criticize the theory of Sushen Dongbei on the basis of archeological data. Prehistoric monuments of the Eastern Area in Heilongjiang Province are Singaeryu remains, Sonamsan remains, Aenggaryeong remains, Seokhoejang remains, Jinheung remains and Aporyeok remains. Residential group in the Eastern Area of Heilongjiang Province lived the economic life of fishing and hunting and were involved with primitive agriculture only in partial area. Its society was patriarchal clan steps of phallocentrism. By considering the cultural exchange between the Eastern Area in Heilongjiang Province and Chinese dynasty, the aspect of cultural exchange in two areas was unascertainable. Therefore, the theory of Sushen Dongbei is a mistake in Chenshou's "Sanguozhi" and nothing but a theory that base on the unified theory of Zhonghua minzu and the nationalistic intention in China.

The genetic structures at one leucine aminopeptidase locus (LAP-A) of acorns, seedling raised in greenhouse and forest form the two beech provenances. West Germany and Rumania, were investigated and compared with each other. In many pair wise comparisons significant differences in genotypic structure as well as genic structure were ascertained between different developmental stages. In both the provenances, the allele $A_2$ seems to have advantage at both seedling stages raised under two different conditions. Homozygous carriers of $A_2$ allele survived best in greenhouse, while heterozygous carriers especially with $A_2$ allele possessed great viability under more variable environmental conditions. Since a distinct different genetic background was present in two base populations, the identical effect of the allele $A_2$ confirms the adaptiveness of this locus. With aid of some measures such as viability parameter and genetic distance, the character of occurred viability selection of further explained. The possible significance of this locus at this early stage is discussed in relation to adaptation of this long lived tree species to heterogeneous environment.
