이영욱 대한흉부심장혈관외과학회 1982 Journal of Chest Surgery (J Chest Surg) Vol.15 No.3
Diaphragmatic eventration is a rare disease, congenital or acquired, high or elevated position of one leaf of the diaphragm muscle, as a result of paralysis, aplasia or atrophy of varying degree of the muscle fibers of the affected side but with no break in the continuity of the muscle. We experienced 3 cases of the diaphragmetic eventration at the department of thoracic surgery, C.A.F.G.H., from 1980 to 1982, which were treated successfully. Among three cases, one case combinded with hamartoma of the ipsilateral lung. Specific complications were not noticed after surgical repair of diaphramatic eventration with good result.
흉부수술 환자에서의 CPK 와 LDH I soenzyme 의 변화
이영욱 대한흉부심장혈관외과학회 1982 Journal of Chest Surgery (J Chest Surg) Vol.15 No.4
A analysis of CPK & LDH Isoenzyme was done on the consecutive patients undergoing thoracic operations from July 1982 to October 1982 in the Department of Thoracic and Cardiovascular Surgery, Capital Armed Forces General Hospital. Eighteen patients were analysed by three groups, such as open heart surgery [group A], major thoracic operation [group B] , minor thoracic operation group [group C]. In all patients serial determination of total level and Isoenzyme of CPK, LDH wad done on preoperative operative and up to 8th post-operative day, The results obtained are as follows. 1. The average value of serum CPK before the operation was 61 IU/L. The value of serum CPK was increased following the operation mainly MM portion and reached to the maximal level of 536107 IU/L in A group 1200191 IU/L in B group, 306150 IU/L in C group on the first postoperative day. The enzyme activity was gradually decreased thereafter and returned to the normal range on the 3rd or 4th day after the operation. 2. The average value of serum LDH before the operation was found to be 83 IU/L. The value was increased during the operation and reached to the maximal level of 481108 IU/L in group A, 14827 I U/L in group B, 10035 IU/L in group C on the second day after the operation. The enzyme activity was gradually decreased thereafter and returned to the normal range on the seventh day after the operation. The enzyme activity was dependent to the duration of operation, severity of muscle damage, type of thoracotomy, effect of extracorporeal circulation, state of disease.
Effects of a Universal Childcare Subsidy on Mothers’ Time Allocation
이영욱 한국개발연구원 2016 KDI Journal of Economic Policy (KDI JEP) Vol.38 No.1
This paper examines the effects of a universal childcare subsidy on childcare decisions and mothers’ employment by using Korea’s policy reform of 2012, which provided a full childcare subsidy to all children aged 0 to 2. I find that the introduction of a universal childcare subsidy increased the use of childcare centers by children aged 0-2, which led to less maternal care compared to that provided to children aged 3-4. However, the expanded subsidy had little effect on mothers’ labor supply. Moreover, the policy effects vary by individual and household characteristics. The effects of the expanded subsidy are mainly found in low-income households and less educated mothers. Highly educated mothers and high-income households are likely to focus more on the quality of childcare service. These results imply that a simple reduction in childcare costs would bring only limited effects on mothers’ time allocation behavior; thus, more attention should be paid to improving the quality of childcare services.

To study the capacity of a lateral load resistance of a joint with Jangbu-connection of Dori-directional frame in traditional wood structure system, 1/2 scaled and T-shaped 7 subassemblies of joint of Dori-directional frame of Deawoongjeon of Bongjungsa were tested. Cyclic Lateral force was applied to column for story drift to be reached 4%. From the experiment, it was shown that the capacity of a lateral load resistance was influenced by the vertical load confining joint and not influenced by the number of Chok and the depth of Changbang. And lateral load resistance mechanism is developed by the restraint between the vertical load and the contacting edge of column; if structure is pushed to the left, the top-right end of Pyeongju contacts with Changbang and left Changbang loses the contacts with Pyeongju and therefore only right Changbang can resist to lateral load.
J시의 사례를 중심으로 살펴본 지역 정보화 콘텐츠 개발방안에 관한 연구
이영욱,연상호 한국콘텐츠학회 2005 한국콘텐츠학회논문지 Vol.5 No.3
This study analyzed the regional current status of city J which has growth potentials of regional information, its necessity and the characteristic of the regional information for this area. The development plans of contents on the regional information based on the construction of the information infrastructure, are proposed to the important fields such as the fields of administration, industry and life information. We have also studied such as the development contents, process, providing of service, evaluation, interaction among the contents, demanders of service and providers of service related to their contents. Therefore proposal to the development plans of contents for the regional information, is able to be brought into much spread of regional information and will contribute to the development of regional information as well as get more competitive regional power. 본 연구는 지역적 정보화의 성장 잠재력과 필요성 및 지역적 정보화 특성 등을 갖추고 있는 J시를 대상으로 지역적 현황을 분석하고 정보화 인프라구조 구축을 기반으로 하는 지역 정보화 콘텐츠 개발 방안을 행정, 산업 및 생활 정보화 등의 주요 분야에 관하여 제시하였다. 또한 콘텐츠 개발내용, 개발과정, 서비스 제공과 평가, 콘텐츠 내용과 서비스 수요자 및 콘텐츠 제공자간의 상호작용 등을 다루었다. 지역 정보화 콘텐츠 개발방안을 제시함으로써 지역 정보화의 확산과 지역 정보화 발전 및 지역 경쟁력 제고에 기여할 수 있을 것이다.
