국회 국토해양위원회 김성곤 의원(민주당 여수갑)이 지난 10월 6일부터 열린 2008년 국정감사에 앞서 '건설하도급업계 위기 원인 진단과 개선방안'이라는 정책자료집을 발간했다. 김성곤 의원은 "건설시장은 아직도 하도급업체에 대한 어음결제 비율이 높고, 건설시장의 구조화된 다단계의 문제점이 존재하고 있다"며 "정부정책에서 중소건설업체와 종사자들에 대한 배려, 따뜻한 정책으로 공정한 시장경제를 이뤄야 한다는 생각에서 자료집을 발간하게 됐다"고 밝혔다. 이자료집은 대한설비건설협회가 건의한 내용을 바탕으로 작성된 것이며, 자세한 내용은 다음과 같다.

In clinical orthopaedics, bone resoption in the cortex is often seen post operatively on X-rays or bone densitometry after total hip replacement (THR) in the form of cortical osteoporosis or atropy. Stress shielding of bone occurs, when a load, normally carried by the bone alone, is shared with an implant as a result, the bone stresses are abnormal and with remodelling analysis this may cause extensive proximal bone resoption, possibly weakening the bone bed to the point of failure. The author made finite element models of the cemented and non-cemented type implanted femoral stem with bone resorption of the proximal medial femur and studied the feed back effect of the various degree of bone resoption to THR system by parametric analysis on the stress of the femoral stem and interface. The results of the present finite element analysis implied that the extent of proximal bone resorption has the effect of more increasing stress on the distal stem tip, cement mantle and interface in both type of femoral stem and this high distal stress possibly can cause the mechanical failure of loosening or failure after THR.

As a channel of a DS-CDMA system is shared among several users, the receivers face the problem of MAI. Also the bandlimited channel leads to ISI. Both components are undesired, but unlike the additive noise process, which is usually completely unpredictable, their space-time structure helps to estimate and remove them. This paper investigates a DS-CDMA system with a fading multipath channel. The investigations have been separated into a channel estimation part and a reception part. In the estimation part of separated two parts, the multipath parameters such as DOA and TOA are evaluated in this paper. In the part of receiver, we used these parameters and tested the performance of this receiver about space-time beamforrners(Decorrelating, Match-Filter, Wiener-Hopf, Subspace-Based). To assess many different estimation techniques and beamformers, the simulation compared with theoretical values is performed.

환상문학이 비상한 관심을 끌고 있다. 여기에는 모더니즘의 퇴조, 문학의 위기의식, 모호한 시대적 상황 등이 맞물려 있다. 흥미로운 것은 한국 고전문학에도 이같은 패턴이 자주 발견된다는 점이다. 우리의 고전문학과 현대문학에서 '환상성'의 중요성은 이제 결코 간과할 수 없다.

The changes in water uptake rate, cooking properties, color of rice grains and gelatinization properties of brown and milled rites during storage were studied. The brown and milled rites were stored at 4 and 25℃ for 5 and 3 months, respectively. The water uptake rate constants of rites during hydration at 30℃ were linearly decreased during storage. The volume increase rate also showed similar trend to the water uptake rate. The terminal point of cooking of milled rice at 100℃ in a sealed brass vessel was about a half of that of brown rice. The cooking rate of milled rice was 1.8 times faster than that of brown rice. The cooking rate constant of both brown and milled rites linearly decreased with the increase of storage time. The L(lightness) value increased for brown rice grain and remained unchanged for milled rice grain during storage. The peak viscosity of rice flours by amylograph increased during storage, but enthalpy for gelatinization decreased, as measured by differential scanning calorimetry.

For abstinence in alcoholics, the follow-up treatment following admission is one of the most important factors. We investigated how many patients had follow-up treatments among alcohol dependent patients who admitted to psychiatric ward at Pusan National University for the first time and which factors influenced on whether they had follow-up treatments. The results were that 12% of the patients had follow-up treatments for at least 2 months after discharge and the longer they had admitted, the older they were on admission, the longer they had follow-up treatments.
