In this paper we provide an alternative explanation for there construction, by assuming that the expletive there (EXPL) has independently uninterpretable Case feature as well as u[person], not as being pied-pipied with $\varphi$-feature. If EXPL has only u[person], we could analyse incorrectly some there constructions, including an embedded infinitive clause: by Chomsky (1998, 1999) in the construction, EXPL is ‘frozen’ and cannot participate in the computation of higher. As a result, we could predict incorrectly that the derivation is crashed. But if EXPL has two uninterpretable features, u[person] and u[Case], we could predict correctly that the derivation is converged: the u[person] of EXPL is deleted under Matching/Agree with $T_{def}$; still, the undeleted u[Case] of EXPL is activating; so EXPL can be raised to [SPEC, T] to satisfy the EPP-feature of matrix T.

Photolysis of diazotetracyanocyclopentadiene has been investigated by means of IR and UV-vis spec troscopy in Ar matrix. Parent carbene is produced in low yield and could be detected by UV-vis spectroscopy and IR spectroscopy. The carbene produced from the diazo compound is very photolabile and also decay thermally at temperature as low as 10K. When the diazo compound is photolyzed the Arrhenius plots show a tunneling effect that is not shown as non linearity.

설계기준사고에 대한 해석을 기초로 하여 운전중 원전의 운전 제한치 및 조치사항을 규정한 기술지침서 (Tech Spec.)는 원자력법에 의거 법적 제재의 효력을 가지며 원전 운전자가 이를 준수함으로서 안전성을 확보할 수 있도록 되어 있다. 그러나 국내 원전 기술지침서의 경우는 해당 노형 공급국별로 상이한 체재의 기술지침서를 도입하여 사용하는 과정에서 많은 문제점이 발생하고 있다. 본 연구에서는 국내 원전 기술지침서 개선을 위하여 현행 국내 기술지침서의 사용상 문제점을 조사하고 그 결과에 대한 분석을 실시하였으며. 최근 미국에서 진행되고 있는 기술지침서 개선작업의 현황을 조사하고 그 적용성을 검토하였다. 새로이 제시되고 있는 기술지침서는 운전 요건의 일관성, 사용자 편이성에서 큰 잇점이 예상되므로 기존 기술지침서 요건의 개정 등 인허가 시에 기준으로 사용될 수 있을 것으로 판단된다.

From the flight safety and the performance point of views, a new engine installation impacts an helicopter development or upgrade program significantly. More than a close relationship between an aircraft manufacturer and an engine manufacturer is necessary for the best integration work from the program initiation phase. In this paper, technical cooperation between aircraft and engine companies, and technical supports by the engine manufacturer for the T700/701K engine during the Surion development program are summarized. The applications of official technical program documents, US Mil-spec, France airworthiness regulations as the standard of the engine installation work, and engineering activities at each phase such as contract, design and manufacturing, flight clearance, ground and flight tests are described. This paper would be a cornerstone for the future domestic helicopter development program.

Historically, performance prediction and sizing of server systems have been the key purchasing argument for customer. To accurate server's sizing and performance prediction, it is necessary to correctness guideline for sizing and performance prediction. But existing guidelines have many errors. So, we examine the benchmarks of performance organization such as SPEC and TPC. And then we consider to TPC-C and TPC-E benchmarks for OLTP server's sizing and performance prediction that is a basic concept of guidelines. Eventually, we propose improvement of errors in guidelines.

UDDI is the open standard for distributed Web-based registry standard which supports registrations and discoveries of Web services. Recently, UDDI version 3.0 specifications were opened by OASIS UDDI Spec, technical committee. UDDI version 3.0 supports many useful functions, which are not supported in version 2.0 specification, such as nested query, enhanced find qualifiers, digital signatures subscription, etc. Despite of its merits, complexity of the standard and backward-compatibility support makes it difficult to adopt this standard in real application domains. In this paper, we develop the Registry server which support UDDI version 3.0 standard. This server is based on common RDBMS and it supports all functions of UDDI version 3.0 including backward-compatibility with version 2.0 API, XML digital signature and URI- based key schemes.

The Purposes of this study are twofold. Firstly, the study investigated the spec of the server environment for managing the academic affairs, and overviewed the theoretical background in connection with the clients and the server as a way of implementing a comprehensive management system for school information which can be effectively utilized for cyber education, multimedia education, joint ownership of learning materials, and educational activities as well as management of the academic affairs using the UNIX-based server, which has lately installed on school thanks to the speedy development of the Internet, Secondly, this study, placing emphasis on practical aspects, attempted to find a method of implementing the web server for constructing a school website in order to provide educational information.

In order to develop a high speed train, various conditions have been considered. Internal noise level of cabins is an important one. In this study, The specification of the interior noise level for KHST(Korean High Speed Train) has been adopted the same level of KTX-spec. In this paper, the interior noise levels of KHST are measured and analysed through the speed and other conditions. According to the speed, the level of internal noise(driver's room(PC2), motorized trailer(TM1) and trailer car(TT2)) is compared. The results of measuring data show that the interior noise levels of KHST are good. And noise levels of this paper are useful in the decision of noise specification.

The purpose of this paper is to investigate the expletives and EPP in Chomsky's(1998, 1999) Minimalism. Generalized EPP is suggested in Chomsky(1998): every functional head may have an uninterpretable selectional feature for its specifier position to be filled by a proper element. After briefly examining the properties of EPP and ${\Phi}$- features in Chomsky (1998, 1999), there-constructions are examined in terms of Agree. EPP features are satisfied by there-Merge or Move of an associate NP. Case feature is regarded as a reflex of ${\Phi}$-feature. Hence, it is suggested that there is a pure expletive with a [person] feature. It has shown that the uninterpretable [person] feature of there is not erased by the nonfinite T($T_{def}$) in terms of Agree in the Raising and ECM constructions. Again the uninterpretable [person] feature of there Agrees with finite T and moves to SPEC-T to satisfy the EPP feature, and finally the uninterpretable [person] feature of there is erased. PRT(=-en) is also regarded as a defective probe with a [number] feature and a [gender] feature.

In this short note we study the torsion theories over a commutative ring R and discuss a relative dimension related to such theories for R-modules. Let ${\sigma}$ be a torsion functor and (T, F) be its corresponding partition of Spec(R). The concept of ${\sigma}$-Cohen Macaulay (abbr. ${\sigma}$-CM) module is defined and some of the main points concerning the usual Cohen-Macaulay modules are extended. In particular it is shown that if M is a non-zero ${\sigma}$-CM module over R and S is a multiplicatively closed subset of R such that, for all minimal element of T, $S{\cap}p={\emptyset}$, then $S^{-1}M$ is a $S^{-1}{\sigma}$-CM module over $S^{-1}$R, where $S^{-1}{\sigma}$ is the direct image of ${\sigma}$ under the natural ring homomorphism $R{\longrightarrow}S^{-1}R$.
