Generally the level of accumulating scheduling knowledge-base in Korean construction companies is in the scheduling knowledge-base infrastructure construction phase and Even in top 10 construction companies, the level is in early scheduling knowledge activity phase. The principle causes of this situation are unawareness of importance to scheduling knowledge and absence of procedure related to scheduling knowledge-base. This research analyzes the problems to accumulate scheduling knowledge-base in Korean construction companies and proposes a procedure model to accumulate scheduling knowledge-base property, which adds items of scheduling knowledge-base infrastructure and scheduling knowledge activity to the existing scheduling procedures of Korean construction companies. Using procedure model for accumulating scheduling knowledge-base, Korean construction companies can develop a new scheduling procedure and accumulate scheduling knowledge accordingly. If scheduling knowledge were accumulated property according to the procedure, a framework for knowledge management system could be provided. 1990년 중반부터 지식(Knowledge)은 국가 및 기업 경쟁력의 원천으로 부상하고 있으며, 건설기업의 공정관리는 건설기업의 핵심 역량 중의 하나이다. 그러나 국내 건설기업은 공정관리에 대한 지식을 체계적으로 저장, 활용하지 못하고 있는 실정이다. 국내 건설기업의 공정관리 지식기반화에 대한 수준은 공정관리 지식기반 인프라 구축 단계에 머물러 있으며, 상위 건설기업 조차도 공정관리 지식 활동 단계의 초기 수준에 머물러 있다. 이는 공정관리 지식의 중요성에 대한 인식 부재, 관련 절차의 부재가 원인이라고 할 수 있을 것이다. 본 연구에서는 건설기업의 공정관리 지식기반화의 문제점을 분석한 후, 건설기업 차원에서 현행 공정관리 표준 절차서의 내용에 공정관리 지식기반 인프라 요소와 공정관리 지식 활동 요소를 보안할 수 있는 공정관리 지식기반화를 위한 공정관리 절차서 모델을 제시하였다. 본 연구의 결과물인 공정관리 지식기반화를 위한 절차서 모델을 통해, 국내 건설기업이 공정관리 지식 활동의 절차를 마련할 수 있는 방안을 제시하고, 추후 국내 건설기업의 건설통합시스템 및 KMS(Knowledge Management System)과의 연계를 위한 공정관리 지식 기반의 구축의 틀을 마련하고자 한다.

A study on the status of sickness and medical care of insured and non-insured groups of employee and his family in Naju fertilizer company, in the year of 1973, was carried out. The results obtained are as follows: 1. 66.8% of all employee was subscribed in this medical insurance program. No woman employee was subscribed and the rate of subscription was increased from 16.1% to 92.0% by age increases. 2. Also, as of period of service, the rate of subscription was increased from 11.3% to 89.4% by the period gets longer. 3. Employee who reside within boundary of the company (76.2%) subscribed more than that whom reside outside boundary (63.9%). 4. Rate of subscription was also indreased by family size becomes larger. In case of single, it was only 19.6% but in the case of family size became more than 6, it increased to 87.4%, 5. As of amount of monthly income, although no one had subscribed those who get less than 30,000 won a month. Subscriber, increased by monthly income get greater. 6. Subscribed family reside within company boundary utilized hospital 35.5 times a year whereas non-subscribed family reside within these utilized 12.5 times. And, subscribed family reside outside boundary utilized hospital 32.2 times a year and non-subscribed family utilized 9.6 times. Regardless of resident area, family who subscribed to this program utilized hospital more often than non-subscribed family. 7. The utilization of the hospital became gradually frequent from 15.6 times to 36.5 times per family by family size became larger. but in non-subscribed group, although it was increased from 8.3 times to 16.5 times per family, it was droped to the least 6.9 times at 2 person family. 8. 17,496 hospital visits were made by all employee and his family in the year 1973. 86.9% of them was made by subscribed group and the rest (13.1%) was made by non-subscribed group. Observing of the type of these sickness by the classification of WHO, only three types of VII (26.7%), XVII (25.0%) and IX(19.3%) were made more often by non-subscribed group while the others were made more by subscribed group. 9. Anual average medical expenditure per family was 13,098.9 won for subscribed family while it was 3,076.1 won for non-subscribed family. 10. Anual average hospital visits per capita was 6.5 times for subscribed groups and 3.4 times for non-subscribed group. Anual average medical expenditure per capita was 2,580.8 won for subscribed group while it was 1,061.0 won for non-subscribed one.

The structures of dehydrated fully Ca2+ _exchanged zeolite A (a: 12.2a3(2) A and of its iodine sorption complex (a=12.258(2) A) have been determined by single-crystal X-ray diffraction methods in the cubic space group. Pm3m at 21(1)℃.the structures were refined to final R(weighted) indices of 0.081 with 206 reflections and 0.084 with 173 reflections, respectively for which I>3 w (I). In each structure. six divalent cations are located on three different theefold axes associated with 6-ring oxygens. Dehydrated Ca2+_A sorbs ca. 6.0 diiodine molecules per unit cell at 80℃(vapor pressure of I: is ca. 14.3 Torr). Each iodine molecule makes a close approach. along its ahs to framework oxygen atom with I-I distance of 2.71(2) A, I-O distance of 3.32(3) k. and I-I-0=180℃. The result indicates that diiodine molecule forms charge transfer complex with framework oxygen. 완전히 Ca2+ 이온으로 치환된 탈수구조(a=12 2f3(2) .41와 이 결정에 요오드가 흡착된 구조(a= 12.258(2) 입)를 21살에서 입방공간군 Pm3m를 사 용하여 단결정 X-선 회절법으로 구조를 해석하였다. 탈수구조는 I>3 w (I)인 206개의 반사를 사용하 여 Rw값이 0.081까지 정밀화되었고 요오드가 흡착 된 구조는 173개의 반사를 사용하여 Rw값이 0.084 까지 정밀화되었다. 각각의 구조에서 단위세포당 6 개의 Ca2+ 이온은 6-링의 산소와 결합하면서 3개 의 다른 3회 회전축상에 위치하였다. 탈수한 칼슘 치환 제올라이트 A는 80살에서 단위세포당 여섯개의 요오드 분자를 흡착하며 각 요오드 분자는 골조 산소 원자와 전하이동 착물을 형성하였다(I-0=3. 32(3) A, I-I=2.7l (2) A 그리고 I-I-0=180℃).
