This study examined the primary tones of news stories and the overall frames which are structuralized by the primary tones in the news reporting of the Private School Law and social conflicts occurring around the law. For this purpose, the study applied Lakoff and Johnson's metaphoric conceptualization to the analysis of the news stories reported in the Chosun Ilbo, the Hankyoreh, and the Kookmin Ilbo, which are considered to represent the audience of the conservative, progressive, and religious forces, respectively. The main goal of this study includes to describe in which manner the newspapers attempt to depict the frames of major social conflicts regarding the Private School Law. The results show that (1) the Chosun Ilbo and the Kookmin Ilbo attempt to structuralize the social conflicts by providing frames of 'freedom is an asset' and a 'war' metaphors; (2) the Kookmin Ilbo applied more frames of a religious metaphor among others; and (3) the Hankyoreh attempts to structuralize the social conflicts by offering frames of 'the front is good, but the rear is bad' and 'war' metaphors, which proves to be the opposite in presenting the overall framing.

Post-grouting for the drilled shaft is known to remarkably increase the end bearing capacity of pile by consolidating and reinforcing the disturbed ground containing slime around the pile tip. However, the general design guideline for post-grouting has not been established yet in Korea. Especially in the domestic application, the post-grouting is employed just for repairing the pile with unacceptable resistance rather than for increasing the design resistance of pile. Therefore, little is reported about the effect of post-grouting on the pile resistance itself. In this study, the effect of post-grouting on the resistance of drilled shafts installed in the weathered rock in Korea was estimated by performing the bi-directional load tests on the piles with and without the post-grouting. The test results presented that the initial slope of end bearing-base displacement curve in the pile with post-grouting was 4 times higher than that without post-grouting. At the acceptable settlement (1% of pile diameter), the end bearing capacities of piles with and without the post-grouting were estimated to be 12.0 MPa and 7.0 MPa, respectively, which indicate that the post-grouting could increase the end bearing resistance of pile in weathered rock more than 70%.

With the social infrastructure being deteriorated, there is a growing need to introduce the asset management to social infrastructure management in order to increase their value and save budget. Social infrastructure asset management is a new concept of facility management in response to these demands. It is defined as a procedure for collecting and analysing facility maintenance data and for making and practicing an economically optimized management plan. Detailed survey work of asset management business is analyzed in order to derive a strategy for asset management information. The contents of IIMM of New Zealand and the asset management definition of the FHWA of the United States, and representative facility management systems of Korea are analysed. The role between organizations and the relationship between business and organization were analyzed. Information required for asset management and for existing facility management systems is compared with business of asset management. In this thesis, three development strategies are suggested. The first one is to develop core business of asset management while excluding duplicated development. The second one is to divide system's structure into three layers. And the last one is to share information by interfacing asset management systems with existing facility management systems.

This study is the secondary full-scale research of a TV drama writer, who has been out of scholarly pursuits. This study examines the Su-Hyeon Kim's differential and tendency in home-drama genre, who has been constructing a general idea of TV drama genre, namely a home-drama, and a melodrama. The purpose of this study is to reconsider the meantime both of exclusive evaluation by the functional measure of social norm, also by the feminism-based evaluation of her drama's supporting role of patriarchal gender ideology. By focusing on her recent highly popular home-drama (2008), this study shows that the writer used her own category grammar strategy of harmonizing both of convention and invention in genre. The conventions in genre are 'a big family', 'a pluralistic construction' 'a realism based on a everyday life', and 'a theme of love of a family with happy ending'. The invention in genre are 'a change of the 1st generation patriarchy', 'a change of the 2nd generation role of a housewife' and a change of the 3rd generation marriage customs'. Also this paper presents that the writer showed a humanistic tendency that pursues a recovery of both 'humanity' and 'love of family based on trusting', which have been destroying by capitalistic ideology, rather than discussing whether her tendency on the gender ideology of patriarchism is conservative or not.

The nuclear power plant(NPP) should be shut down for inspection and tests prior to a return to power if the earthquake exceeds the operating basis earthquake(OBE). The OBE at the plant is considered to have been exceeded if the computed cumulative absolute velocity(CAV) from the earthquake record is greater than 0.16g-sec. However, the CAV criterion should be determined considering the seismic and structural characteristics of the plant. An experimental study using shaking table is conducted in this study to evaluate intensity of CAV criterion. Appropriate level of CAV is evaluated based on the test results using the developed seismic damage indicator(SDI) model. The model consists of stacked acrylic cylinders and is developed to behave consistently for each directional seismic load. The result of the experimental study in dicates that the CAV criterion of 0.16g-sec is conservative enough to be applied to Korean NPPs since the CAV value of the seismic input motion of the Korean standard NPPs ranges from 0.3 to 0.5 g-sec. The developed SDI is expected to be useful not only in easily determining OBE exceedance but also in evaluating earthquake damage quantitatively to provide guidelines for better post-shutdown inspection and test.

Excepting tunnel of dorimstream - ccachimountain station section, the subway line No.2th section was build using ASSM and NATM methods because of soil pressure and land condition. The way of dealing underground water was selected without sufficient preconsideration of geographical features, ground condition, influence of lowing underground water, and long-term cost of running maintenance so that the form of undrained tunnel was build having decreased construction characteristics and technically improper elements. The form of partial drainage is very difficult to manage structures of tunnel, because water leakage, water pressure causing cracks of lining concretes and scaling are constantly happened. so partial drainage suggest that setting reinforced Anchor Bolt to prevent buoyancy and should increase center drainage way up to height of railroad. Partial drainage suggest that holey pipe(${\phi}$350mm) manhole, drainage checking pipe manhole are should be regularly dredged, when changing roadbed(gravel${\rightarrow}$concrete) drainage checking pipe manhole should be build and setting a limitation of entering underground water's quantities. Beside drainage degree in changed section of structures causing instability of structures is continuous degree. so if efficient drainage way and the patterns of flaws, problems are considered in survey, it will be expected to have a advantage condition in maintenance part.

만약 사용자가 원하는 멀티미디어 콘텐츠를 원하는 시간에 TV를 통해서 볼 수 있게 된다면, 다시 말해서 보고 싶을 때, 보고 싶은 방송을 포함한 멀티미디어 콘텐츠를 원하는 시간에 바로 볼 수 있게 된다면 사용자는 방송시간에 맞추어 TV를 보지 않아도 되고 원하는 콘텐츠를 검색하느라 시간을 보낼 필요도 없어질 것이다. 예약 녹화의 경우에는 시간정보를 가지고 미리 예약을 해야 하는 경우이므로 이와는 다른 경우라 하겠다. 이러한 서비스는 바로 디지털 콘텐츠와 이를 가정에서 저장할 수 있는 장치의 발달이 바탕이 되고 있다.(표 1 생략, 원문이미지 참조) 표 1은 영국의 BBC사에서 1998년에 조사한 자료로 디지털 멀티미디어 데이터를 저장하고 재생할 수 있는 저장장치의 가격과 용량의 전망을 나타낸다. 여기에서 데이터는 5.5 Mbps급의 MPEG-2 스트림을 기준으로 하였다. 표 1에서 보수적 견해는 매 18개월마다, 현실적 견해는 매 10개월마다 동일 가격의 용량이 2배가 되는 것으로 계산한 것이다. 여기서 보듯 저장장치의 가격 대비 성능이 갈수록 나아지고 있어 가정에서 멀티미디어 콘텐츠를 저장할 수 있는 가정용 서버의 등장이 멀지 않았음을 보여준다. 1999년 가을에 활동을 접은 DAVIC의 마지막 활동이 바로 이러한 저장장치를 이용한 "TV Anytime Service"였다 . Anytime Ser vice란 저장장치를 통해 사용자가 원하는 콘텐츠를 저장해 놓았다가 사용자가 원하는 시간에 언제나 볼 수 있다는 개념이다. 이를 소비자관점에서 보면 Personalized service라고 할 수 있다. 이어 1999년 여름에 창설이 된 "TV Anytime Forum"이라는 단체에서 이러한 저장장치를 이용한 서비스를 위한 환경을 구축하고 있다. TV Anytime Forum은 가정에서 저장장치가 있는 단말인 PDR(Personal Digital Recorder)을 이용한 서비스, 즉 Anytime Service 위한 응용을 가능하게 하기위한 콘텐트 개발자에서부터 가전기기에 이르는 분야에서 Interoperable한 규격을 만들어 보자는 것이 그 목적이다. 특히 여러가지 디지털미디어 전달방식, 예를 들어 DVB, ATSC, ARIB 등에 독립적인 규격을 만드는 것을 원칙으로 하고 있다. 1999년 7월에 첫 번째 회의를 하면서 설립이 되었다. 2001년 말 기준으로 BBC, NHK, Microsoft, Sony, IBM, Phillips, NTT, Intel, Canal+, Tivo, 대우전자, 삼성전자, LG전자, KETI, ETRI 등 콘텐츠 사업자, 방송업자, 네트웍 사업자, 가전업체, 소프트웨어 개발회상에 이르기까지 총 157개 회원사로 구성되어 있으며 년 6회 회의를 개최한다. 2000년 11월에는 서울에서 회의를 개최하였으며 2003년 6월에 다시 한국에서 개최하기로 확정되어 있다. 본 글에서는 이러한 Anytime Service 환경이 구축되었을 때의 각 산업별로 얻을 수 있는 이득에 대해서 알아보고 TV Anytime Forum의 각 Working Group들의 작업 내용들, 그리고 지난 1월에 열렸던 15차 회의의 결과들에 대해서 살펴보고 국내의 TV Anytime 활동에 대해서 간단하게 소개하고 마치도록 하겠다. 현재 디지털 방송기술, 비디오 스트리밍 기술이나 MPEG 등과 같은 기술수준으로도 충분히 이러한 서비스를 시작할 수 있으며 소비자들도 이러한 욕구를 서서히 느끼고 있다. 정보와 서비스를 선택할 수 있게 만들자는 목표를 설정하고 있다. 이러 목표는 통신$.$컴퓨터$.$멀티미디어 기술발전으로 가능하게 되었다.

The exposure dose form recycling of a large amount of the steel scrap from the KRR-1＆2 decommissioning activities was evaluated, and also the clearance level(draft) was derived. The maximum individual dose and collective dose were evaluated by modifying internal dose conversion factor which was based on the concept of effective dose in ICRP 60, applied to the RESRAD-RECYCLE ver 3.06 computing code, IAEA Safety Series 111-P-1.1 and NUREG-1640 as the assessment tool. The result of assessment for individual dose and collective dose is 23.9 $\mu$Sv per year and 0.11 man$.$Sv per year respectively. The clearance levels were ultimately determined by extracting the most conservative value form the results of the generic assessment and specific assessment methodologies. The result of clearance level for radionuclides( $Co^{60}$ , C $s^{l37}$) is less than 1.14${\times}$10$^{-1}$ Bq/g to comply with the clearance criterion(maximum individual dose : 10 $\mu$Sv per year, collective dose : 1 man$.$Sv per year) provided for Korea Atomic Energy Act and relevant regulations.s.

Regulations and guidelines for radioactive waste disposal require detailed information about the characteristics of radioactive waste drums prior to transport to the disposal sites. However, estimation of radionuclide concentrations in the drummed radioactive waste is difficult and unreliable. In order to overcome this difficulty, scaling factor (SF) method has been used to assess the activities of radionuclides, which could not be directly analyzed. A radioactive waste assay system has been operated at Korean nuclear power plant (KORI site) since 1996 and consolidated SF concept has played a dominant role in the determination of radionuclide concentrations. However, SFs are somewhat dispersive and limited in KORI site. Therefore establishment of the assay system using more improved SFs is planned and progressed. In this paper, the scope of research is briefly introduced. For the selection of more reliable activity determination method, the accuracy of predicted SF values for each activity determination method is compared. From the comparison of each activity determination method, it is recommended that SF determination method should be changed from the arithmetic mean to the geometrical mean for more reliable estimation of radionuclide activity. Arithmetic mean method and geometric mean method are compared based on the data set in KORI system. And, this change of SF determination method will prevent an inordinate over-estimation of radionuclide inventory in radwaste drum.

The exposure dose form recycling on a large amount of the steel scrap from the KRR-1&2 decommissioning activities was evaluated, and also the clearance level was derived. The maximum individual dose and collective dose were evaluated by modifying internal dose conversion factor which was based on the concept of effective dose in ICRP 60, applied to the RESRAD-RECYCLE ver 3.06 computing code, IAEA Safety Series III-P-1.1 and NUREG-1640 as the assessment tool. The result of assessment for individual dose and collective dose is 23.9 ${\mu}Sv$ per year and 0.11 man$\cdot$Sv per year respectively. The clearance levels were ultimately determined by extracting the most conservative value form the results of the generic assessment and specific assessment methodologies. The result of clearance level for radionuclides($Co^60$, $Cs^137$) is less than $1.67{\times}10^{-1}$ Bq/g to comply with the clearance criterion(maximum individual dose : 10 $\muSv$ per year, collective dose : 1 man$\cdot$Sv per year) provided for Korea Atomic Energy Act and relevant regulations.
