Recently, the term 'Provisional Sum(PS)' has been used in domestic public construction projects especially for civil works. Nevertheless, the guideline for PS has not been clearly stipulated in contract documents or construction-related laws. Due to these ambiguous contract situations, disputes between owners and contractors are surely expected to settle down PS in construction projects. This paper focused on suggesting a guideline to settle down PS in these ambiguous contract situations. The guideline suggested in the paper is expected to be used as a reasonable method to settle down PS avoiding nonproductive disputes about PS in construction projects

모성역할 획득에 영향을 주는 변수를 이해한다는 것은 모성역할 획득에 대한 체계적인 연구와 실질적인 간호중재를 가능하게 한다. 생후 4개월된 첫 아기가 있는 어머니를 대상으로 모성역할 획득모형을 발전시키려고 이 연구를 시도하였다. 가설적 모형은 5개의 변수(모성역할 획득, 모성역할 긴장, 일상생활의 시간적 여유, 아기 기질, 사회적지지)로 구성되었다. 대전시에 거주하는 대상자에게 전화를 통하여 동의를 얻은 후, 우편으로 250명에게 질문지를 보내어 161명(64.4%)으로부터 회수되었다. 자료를 Lisrel 프로그램을 이용하여 공변량구조분석을 한 결과, 자료와 가설적 모형과의 전반적 지수는 자유도 21에 카이자승치 31.47, GFI와 AGFI의 값은 .970, .935였고, RMSR, NFI, NNFI는 각각 1.668, .9097, .9425이었다. 간명하고 부합도가 더 좋은 모형을 찾기 위하여 통계적 결과와 이론적 적합성에 따라 2경로(아기기질에서 모성역할 획득, 모성역할 긴장에서 모성역할 획득)를 고정시켰다. 수정모형의 PFI (간명도)가 .7297로 증가하여 수정모형이 더 간명하면서도 부합도가 좋은 모형으로 나타났다. 공변량구조분석 결과 나타난 변인간의 관계는 일상생활의 시간적 여유가 많을수록, 사회적 지지를 많이 받을수록, 아기기질이 순하다고 생각할수록 모성역할 긴장은 적었고, 일상생활의 시간적 여유가 많을수록, 사회적 지지를 많이 받을수록 모성역할 획득은 잘 되었다.

의사에게 있어 자신의 적성과 능력에 부합하는 세부 전공을 선택하는 것은 자신의 자아실현뿐만 아니라 환자들에게도 중요한 의미를 갖는다. 이것은 의과대학생들의 전공 선택을 위해 의과대학 재학 중에 이루어지는 진로개발의 중요성을 시사한다. 이 글은 의과대학생 개개인의 적성과 소질에 따른 전공 선택을 어떻게 지도할 수 있는지 단계별 진로지도 전략에 대해 고찰하였다. 전공 선택 지도의 첫 번째 단계는 자기평가이다. 자기평가는 자신의 적성과 능력에 맞는 전공을 선택하기 위해 스스로에 대한 정보를 모으고 이해하는 과정이다. 두 번째는 전공탐색 단계이다. 이 단계는 자신의 적성과 능력에 부합할 가능성이 높은 전공과목에 대한 정보를 수집하는 것이다. 세 번째는 전공 선택 단계이다. 이 과정은 학생 스스로에 대한 자기평가 결과 및 전공에 대한 탐색 결과에 기초하여 자신이 어떤 분야에 더 적합한가에 대한 의사결정을 하는 과정이다. 전공 선택을 위한 접근 방법의 마지막은 전공 영역의 수련을 위해서 자신이 결정한 전공 선택을 이행하는 단계이다. 이 단계에서는 자신이 선택한 전공영역, 그리고 전공의 수련교육과정을 제공하는 교육기관에 응시원서를 제출하고, 면접을 실시하는 과정이 포함된다. 의과대학생들이 자신의 적성과 소질에 따른 전공 선택과 의과대학생 개개인의 선택의 문제를 넘어 의료 인력의 수급, 의료서비스의 질적인 수준과 밀접하게 관련되어 있다. 그러므로 의과대학은 대학의 책무성 수행차원에서 학생들의 가치관 확립과 진로지도를 위한 체계적인 학생 진로지도 프로그램을 개발하고 학생들을 적극적으로 지원해야 한다.

This paper analysed a bulk of theses performed in various perspectives relating to College Scholastic Ability Test since 1994. Further this searched suggestions of revisions of systems about College Scholastic Ability Test along with the revised curriculum throngh this analysis of previous studies, which were categorized into 'correspondence between goal and characteristics', 'impact on education', and 'impact on society'. According to previous studies, they treat crossing application, advantage & disadvantage among optional subjects, difference in subject and content between natural science and cultural science, subjects that have to be included into College Scholastic Ability Test. This research suggests some elements and basic & fundamental information which need to be considered in the process of revising in problem making system of College Scholastic Ability Test.

This paper resents a prediction method of natural frequencies of coupled horizontal and torsional vibration of hull girder based on design sensitivity analysis in case of the changes of system parameters. The sensitivity analysis is formulated applying the direct differentiation method and transfer matrix method. In the analysis, warping, shear deformation due to torsion and the continuity condition at the connected part of open and closed hull section are considered. Using the presented method. The affection for natural frequencies by the change of system parameters, especially cargo and added mass and their centers, is numerically investigated for a real large container carrier.

This study try to attempt to manage on-line system of land cadastral by computing land registration information, for application to computerized cadastral work through Geo-Spatial Information System. And also, in order to consult D/B of cadastral information, cadastral non-coincidence area uncapable to D/B when land-survey, taking advantage of GSIS drawing made by the present condition drawing and the aerial photograph survey by general survey, makes actual cadastral control point by some selected investigators. And so, it can be compared and analysed by the result of the present survey and, through the interpretation of the relatives, it aims to improve the precision of survey technique in consulting cadastral information D/B in the future.

A Internet user can easily access to the target information by web searching using some key-words or categories in the present Internet environment. When some meta-data which represent attributes of several data structures well are used, then more accurate result which is matched with the intention of users can be provided. This study proposes a multiple dimensional vector tagging method for the small web user group who interest in maintaining and sharing the bookmark for common interesting topics. The proposed method uses vector tag method for increasing the effect of categorization, management, and retrieval of target information. The vector tag composes with two or more components of the user defined priority. The basic vector space is created time of information and reference value. The calculated vector value shows the usability of information and became the metric of ranking. The ranking accuracy of the proposed method compares with that of a simply link structure, The proposed method shows better results for corresponding the intention of users.

A rapidly developed satellite technology is used in comprehensive fields such as spatial data aquisition and applications. Especially a GPS positioning is expected to reinvigorate at the national reference system changes to ITRF (International Terrain Reference Frame). Currently the National Geographic Information Institute (NGII) issues a triangulation point coordinate by separating old and new coordinates and in the year of 2007 it will be scheduled to be changed ITRF. The triangulation point coordinate in Cheju area causes some problems due to the difference original observation and re-observation. Thus in this study a GPS observation is conducted after re-organizing geodetic network based on 1st and 2nd order triangulation in order to check the current triangulation points in Cheju area. After the GPS observation data analysis, stable points were extracted, proposed a geodetic network and its application.

The aim of the study was to develop an objective measurement tool, which could measure radiation safety regulations as an advanced research to draw evidentiary conclusions for the rationalization of radiation safety regulations as organizations continuously increase consumption of radiation material. The survey was based on the contents of Vol 1~21 of US NRC NUREG 1556 (Consolidated Guidance About Materials Licenses) and material from the Nuclear Safety Act which was based on radiation safety managers who are responsible for about 10% of the domestic registered organizations for radiation usage. As a result of the analysis, 3 main causes were extracted based on 20 questions. Each causes were named as Cause 1: 'Radioactive Safety Regulations Requirements', Cause 2: 'Compatibility of Actual Safety Regulation', and Cause 3: 'RI/RG radiation Source Classification' respectively. The dispersal explanations of each causes were explained in total of 60.417% by 40.140% of Cause 1, 13.721% of Cause 2, and Cause 3 for 6.556% If radiation safety regulation standards are drawn using the radiation safety regulation measurement tool, which is suggested in this study, this could be not only comply with international standards but also could be used to propose a practical standard to domestic radiation safety managers.

In this paper, the liquid air was selected as the refrigerant in artificial ground freezing to be used for rapid ground freezing and to reduce the risk of suffocation and the applicability of liquid air was verified. In order to evaluate the stability of the liquid air, the oxygen concentration of mixtures with liquid nitrogen and liquid oxygen was experimentally examined to meet the oxygen concentration criteria in the Occupational Safety and Health Act. In addition, the effects of the mixture ratio of liquid nitrogen and liquid oxygen, pressure and flow rate change in the storage vessel on the oxygen concentration in the liquid air were investigated. As a result, the ratio of liquid nitrogen and liquid oxygen 8: 2 was shown to meet the oxygen concentration standards. Pressure and flow rate change in the storage vessel did not have significant effects on the oxygen concentration in the liquid air.
