The purpose of this study is to analyze the degree of risk of the working unit of nuclear power plants construction. In order to do this, and the risk index by type and source of risk judgment derived in the previous study were utilized. Further, to derive a risk index of unit work in nuclear power plant construction, a survey targeting safety professionals was conducted. The analytic hierarchy process (AHP) was used for analysis of the survey. The following results were obtained. Firstly, the results of AHP showed that main building work is the most dangerous work, and base excavation work is the second dangerous work among 21 unit works. Secondly, so, it is required to invest more and to take a increasing interest in unit works of civil and architecture as compared to other unit works. Further, the results could be used to reduce the degree of risk in construction of the nuclear power plant.

일반적으로 암판정을 수행하기 인해 가장 널리 사용되는 방법은 암석의 강도와 절리의 발달빈도를 고려하는 것이다. 하지만 미세균열과 연장성이 긴 절리들이 암반에 존재하고 있는 경우에는 이러한 방법이 합리적이지 않다. 그러므로 복잡한 지질조건을 가지고 있는 암반에서의 굴착난이도 결정은 절리빈도와 실내시험(일축압축강도, 점하중강도, 실내탄성파속도 등)과 현장탄성파속도와의 상관관계를 종합하여 암판정을 수행하는 것이 더욱 더 합리적이라고 판단된다.

Underground construction requires long construction duration and a variety of equipment, and environmental management and improvement of its activities are considered necessary. For the purpose of the environmental improvement of underground construction activities, the appropriate development of technologies to reduce generated pollutants is mandatory. However, the analysis of the needs of technology development and the evaluation of development priorities should take precedence. In this research, the needs for the improvement of each construction activity are analyzed as a preliminary study for a proposed technology development plan to improve the environmental performance of underground construction. Firstly, environmental problem factors caused by underground construction activities are determined while underground construction types, methods, and activities are classified. A questionnaire survey to determine the needs for the improvement of each activity is then carried out. The survey indicated that the most urgent activity to be improved is that of cutting excavation, which causes environmental problems associated with flying dust. This study could be used as a basis for a technology development plan for the environmental improvement of underground construction activities. The result of this study, the priority of improvement needs, contributes to the effective allocation of a limited Research and Development (R&D) budget.

Korea has many underwater cultural heritages within the east, west and south seas surrounding the Peninsula that indicate historically important sealanes for trade and transportation. As these underwater cultural heritages are the objects of despoilment because of their relatively easy access through modern technology, their often high historical and priceless value demands strong protection similar to or better than the land cultural properties. Currently, Korea does not have any concrete laws or regulations for the protection of underwater cultural heritages. Thus, these heritages iu, somewhat temporary and inappropriately subjected to laws and regulations relating to provisions of individual Laws concerning protection of cultural properties act, and statute of excavation of material fir buried national property, lost articles act etc.. Internationally, the UNESCO Convention on the Protection of the Underwater Cultural Heritage was adopted but not yet entered into force. Therefore, the protection of underwater cultural heritage has become an urgent matter. In this regard, this article's main purpose is to provide recommendations for improving direction of legal regime and policy for protecting our underwater cultural heritages. These legal regimes need provisions for definition of the underwater cultural heritage, scope of application, ownerships, jurisdictions and protection measures. And suggestions are provided in regard to policies for the protection of underwater cultural heritages that may improve organization and cooperation among concerned ministries and agencies, compensation system, restrictions for excavation of underwater relics, efficiency of survey of underwater surface and information system.

This study is to excavate superior fishing communities by applying the Ostrom (1990)'s principles of sustainable and successful use of common goods. Ostrom(1990)'s principles are (1) clearly defined boundaries (2) congruence between appropriation and provision rules and local conditions, (3) collective choice arrangements (4) monitoring (5) graduated sanctions (6) conflict-resolution mechanism (7) recognition of rights to organize by external government authorities (8) nested enterprises. The survey was carried out under the individual interview method of 15 fishing village members in 32 fishing communities with the government's fishery environment improvement and fishery creation projects. The total effective samples are 477. These data were analyzed. The analysis result shows that 24 fishing villages are selected among the 32 fishing communities in the samples, including Nanji, Sanghwang, Songseok, Sinshido, Jukyo, Jinsan, Changli, Pado, Beopsan, Rahyang, Palbong, Woongdo, Daehwang, Sapsi, Chido, Jinri, Daeri, Songgak, Joongwang, Ojii, Doripo, Doseong, Mongsan 1ri and Songnim as superior fishing villages. The results of this study have limitation that may vary depending on the rigor of the criteria in the process of deriving good fishing communities. Despite this limitation, this study has expanded existing research focused on validating the theoretical applicability of the framework through case analysis of specific fishing communities to objectively and quantitatively to many fishing communities. The results of this study are expected to contribute to the creation of conditions in which fishermen can continue to manage their fishing grounds and stand on their own feet by presenting the framework and principles for developing desirable fishing village models for the continued use of mudflat shells grounds as the common goods.

The purpose of this thesis is to understand the shape of The Sijeon (Licensed-Markets) established around the Jongno and Namdaemun-ro Avenues in Hanyang during the Joseon Dynasty in the 19th and 20th centuries and then to examine the relationship with the urban structures of Hanyang City. By investigating the excavation results of the Cheongjin and Gongpyeong areas, drawings, photos, and documentary records related to the city, this study classified the building types in the Jonggak area. As a result, since the 19th century, the basic form of Sijeon with 2 Gan(間, bay) in the front facade and 3 Gan(間) on the side, in other words, 5M in the front and 8M in the side was arranged in parallel, and it was a type with a corridor-type courtyard inside. The inner sides of Jongno Avenue had an atypical flat shape that suited the more free lot, and a courtyard-type plan with a single entrance was also confirmed in the one or two Bang(房, district). This study reflected the operation method of the Sijeon buildings b between the one unit and the other units, which affected the internal spatial structures, and it found that the size and style of the Sijeon buildings were closely relevant to the size of the lots near Jongno Avenue.

This paper aimed to identify architectural historical meaning of the brick-constructed platform of the west hall in Hwangnyoungsa buddhist temple site based on studying published the excavation survey report and comparing with other platforms of Silla remains. Mass and height of the building has a hierarchical structure within a buddhist temple site, this is applicable in Hwangnyongsa. So in case of a rank equal to or lower buildings than the west hall, those of platforms were built of brick-constructed. As stone relics, jidaeseoks are very narrow, I think that wooden pagoda and main hall's platform were built of brick in first construction period. West hall's platform was built at the late 6th~the mid of 7th century, these brick-remains were considered as a quite earlier construction period relics. Because in west hall there is no jidaeseok under bricks, and all bricks relics have a rectangular shape.

This study presents methodology and tools for remote measurement of the orientation of the rock parting surfaces. Two close circuit video camera capture the pictures of a rock excavation surface while a laser beam scans the surface. Positions of the laser beams in the two digital images are recognized by image processing. Using the stereoscopic concept, three dimensional coordinations of the rock surface and the orientation of the rock parting planes are calculated. Point, cross and line type laser beams are tested for better image processing results and measurement accuracy of the coordinates. According to a simple accuracy test, cross beam show better results than the point beam. However, line beam show more promising results for the measurement of the rock parting surfaces.
