This study aimed at examining if the original memory remains after a misinformation is presented, using Event-Related Potential based Concealed Information Test (ERP-based CIT). In the first stage of the study, the participant was presented with either the original information or a misleading information after experiencing an event (Post-information). The second stage was to measure brain wave and reaction time on the original, misleading, and irrelevant information (CIT-Stimulus). P300 amplitude, P300 area, P300 latency, and reaction time were used as dependant variables. In the result, a significant Post-information ${\times}$ CIT-Stimulus interaction effect was found on the P300 area measured at Cz, Pz, and Oz area. This interaction effect implied the possibility that the original information could be partially impaired in memory by misleading information presented afterward. P300 amplitude at Pz area did not differ between the accurate and the misleading stimuli in the condition in which a misleading information was presented. This result can be explained by source monitoring error. In discussion, the limitations of this study and directions of future studies were discussed.

Artificial insemination of cryopreserved semen is not practiced in broiler breeder industry although its benefit has been recognized for years. Thus, the present study explored the possibility of artificial insemination with cryopreserved semen in Ross broiler breeders. Sixty Ross female broiler breeders were artificially inseminated either with fresh or with cryopreserved semen pooled from five male Ross broiler breeders. On.e hundred eighty eggs were collected from each semen treatment and hatched. Fertility and hatchability of fertilized eggs collected from hens artificially inseminated with cryopreserved semen were 68.0 and 47.1％, respectively, compared to 88.3 and 87.2％ with fresh semen. Both unfertilized eggs and dead embryos during hatch were significantly (P<0.05) higher in the cryopreserved semen­treated group by approximately 2.7­ and 3.2­fold than the fresh semen­treated counterparts. the moderately low fertility and markedly low hatchability of fertilized eggs obtained from cryopreserved semen observed in this study may be of practical interests in broiler breeder industry and deserves further study.

Amid the recent intensification of climate change, the decline of subalpine coniferous species is evident. Accordingly, the Korea Forest Service is conducting research to establish conservation measures, identify the causes of the decline of subalpine coniferous species, and establish conservation strategies for seven species of conifers in the alpine region. This study used an economic value evaluation method to present objective data to inform the need for and value of conservation of endangered coniferous species through the recognition of endangered coniferous species and evaluation of conservation value among coniferous species conservation strategies in endangered alpine areas. A contingent valuation method was applied. As a result, the estimated conservation value per household of endangered alpine coniferous species was 49,181 won.

To measure the depth and extension on the surface cracks of the stone monument, ultrasonic pulse velocity targeted at the Mulgyeseowon Stele in Changnyeong was used in this research. Additionally, to establish a long-term countermeasure of management and conservation for this stele, we have investigated the material properties and damage on it and have conducted a precise diagnosis by a variety of non-destructive techniques. Our research has revealed that stones of the stele are composed mainly of three rock types according to the parts of it, alkali-feldspar granite, gabbro and diorite. The result of the deterioration evaluation has occurred that cracks, which are observed from every direction in the body of the stele, are the significant factors to reduce structural stability. The ultrasonic velocity for an evaluation on the properties of the stele has revealed that the speed was high in the order of body, pedestal and crown. Furthermore, to understand the present condition and occurrences of the cracks which have measured in many different forms on the stele quantitatively, we have estimated from 0.6 to 24.1cm deep of the cracks by To-Tc method using ultrasonic velocity.

건축가 故배기형. 그의 심미관과 독특한 건축세계는 예리한 해부학적 관점과 결부되는 구성에 크게 비중을 두면서도 거기엔 새로움이 스며있다. 지금도 우리는 한일은행 을지로지점(1962), 한전 영월 제2화력 발전소(1962), 유네스코빌딩(1966) 등 건축사에 기록된 작품들에서 그의 건축가로서의 완숙된 건축적 기량과 높은 전문성을 읽을 수 있다. 그러나 막상 건축가 배기형에 대한 연재를 시작하려다 보니 안타깝게도 그의 건축가로서의 행적에 관한 자료가 많지 않을 뿐더러 성장과정 역시 그와 가까웠던 몇몇 분들의 증언에 의존할 수 밖에 없다. 그래서 본지는 고 배기형 선생의 문하생이었던 인하대 원정수교수의 도움을 얻어 그에 관한 기록과 자료를 찾는 일에서부터 시작해 주변인물들의 증언을 통해 건축가로서의 역정과 작품세계를 총3회에 걸쳐 연재한다.

The concept of Government 2.0 is spreading rapidly in many countries and is fundamentally changing existing freedom of information system which has passively responded to information demands. This study aims at discussing possible strategies for a new freedom of information system that is based on the Government 2.0 notion which presents revolutional approaches to public sector information's creation, management, and usage. For the purpose of the study, precedence studies and researches about both freedom of information system and Government 2.0 are analyzed. Furthermore, mutual relationships between them are discussed. Through this discussion, social and economic benefits from freedom of information systems which are based on Government 2.0 are explored. As a case study, Data.gov services in the US, the UK, and Australia which are recognised as a feasible plan to set up Government 2.0 are analyzed. Their three common characteristics- revaluating public sector information's reuse, establishing exclusive agencies, and providing raw data-are discussed. Then, various mashup services which use Data.gov services' raw data are also studied. Issues related to the freedom of information system in South Korea are examined. As a result, a policy framework for establishing Government 2.0 based freedom of Information system is discussed in terms of three aspects, law, technology and organization.

본 연구에서는 비선형 FEM 해석을 이용하여 PSC(Prestressed concrete)와 강으로 구성된 혼합구조 보의 휨 실험을 검증하였다. 혼합구조 보의 거동에 가장 큰 영향을 미치는 연결부는 Perfobond rib로 구성된 경우와 스터드로 구성된 경우를 고려하였다. 이종 재료가 접하는 경계면의 상호 작용에 대해 완전합성과 부분합성인 경우를 고려하여 혼합구조 보의 비선형 해석을 수행한 후 해석 결과와 실험 결과를 비교하였다. 하중-처짐관계, 파괴 형상 등의 해석 결과를 실험 결과와 비교한 결과, 부분합성을 고려한 모형이 실험 결과와 유사한 거동을 보였으며 또한 Perfobond rib를 갖는 실험체가 스터드를 갖는 실험체보다 해석 결과와 비교 시 안전측의 결과를 나타냈다.

This study was conducted to confirm the possibility of a new carbon stock in the Sejong National Arboretum, a major urban greenspace in Sejong-si. This study involved field and ground surveys of 1,336 trees, including 794 Pinus densiflora trees with a diameter at breast height (DBH) of above 5.5cm, which are the most planted in the Sejong National Arboretum, Chionanthus retusus 154 trees planted, Metasequoia glyptostroboides 216 trees, and Aesculus turbinata 172 trees as street trees. Measurements were performed from April to November. Based on the results of the survey, the carbon storage and annual carbon stock were calculated using the annual carbon stock estimation equation used in the forest carbon offset projects. As a result of comparing the carbon stock of the 12cm diameter class, which is the most distributed of four major trees, it was found in the order of C. retusus (0.0136tC/tree), P. densiflora (0.0126tC/tree), M. glyptostroboides (0.0092tC/tree), and A. turbinata (0.0076tC/tree). In addition, the field survey measurement data compared with terrestrial LiDAR measurement data for 20 trees showed a difference of 10.0cm in tree height and 1.7cm in diameter at breast height (p<0.05). In the future, additional carbon stock and annual uptake of other species planted in the arboretum are expected to promote the carbon uptake effect of the arboretum and contribute to the achievement of the national NDC. In the long term, it is also necessary to develop the carbon uptake factor of trees and shrubs mainly used to calculate the exact carbon uptake amount of trees mainly used in urban forests and gardens.
