본 연구는 건설시장 개방에 따른 표준계약조건을 정립하기 위해 FIDIC 제정 계약조건과 국내에서 계약조건으로 적용되는 관련법규의 내용을 문헌조사를 통해 비교ㆍ검토하였다. 국내계약조건은 공사관련 사항을 여러 법규에 산발적으로 규정하고 있어 비정형성을 보이고 있으며, 책임기준 또한 모호하며, FIDIC 조건과의 비교분석에서 알수 있듯이 세부적ㅇ니 면에서 많은 차이점을 보이고 있어 클레임의 발생가능성이 높음을 알 수 있었다. 또한 클레임과 분쟁의 처리절차에 있어서 국내계약조건은 클레임의 제기, 감리자의 책임과 권한, 클레임의 유효성 기준, 클레임의 처리절차에 대한 규정이 미비한 실정임을 알 수 있었다. 또한 FIDC 계약조건의 분석을 통하여 시공자가 제기할 수 있는 클레임 사항을 본 연구에서는 제시하고 있다. IN this study, with a purpose to establish the standard construction contract conditions, the FIDIC conditions of contract and the corresponding legal systems from the various domestic laws and regulations, used as the construction conditions, were compared. The study shows problems such as inconsistence and atypicality between current provisions and FIDIC contract. The possibility of claim occurrence in Korea construction market is significant. Through a comparison of domestic and foreign construction contract, the study presents that domestic contracts don't have provisions about procedure of submission, engineer's responsibility and authority, and effective procedure of claims. The study also presents technical considerations under the FIDIC Contract by Employer and Contractor.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

The purpose of this study was to remove the excessive air foaming which was produced in mixing the RSLMC(latex-modified concrete with rapid-setting cement) by choosing the best antifoam agent type. A series of RSLMM(latex-modified mortar with rapid-setting cement) experiments were carried out as a basic experiments for RSLMC with the main experimental variables such as antifiamer types (A, B, C, D), antifoamer contents(0, 1, 2, 3%), and latex contents(10, 15%). Air content test and compressive strength tests were carried out to measure the improved properties of RSLMM. SEM analysis, also, was carried to observe the formation of latex film. The results of RSLMM showed that the decrease of 50% air content was obtained by admixturing an antifoam agent by 1%. This made the strength enhanced and the workability be within the purposed. The best properties of compressive strengths was obtained at latex content of 15% and D antifoam agent of 1%. compressive strength increased about 32.6%. The analysis of SEM results no difference in a formation of later film.

이동학,정연권,정선태 崇實大學校 生産技術硏究所 2001 論文集 Vol.31 No.-

In display systems employing an analog monitor, the tearing artifact such that an window screen is divided into two parts showing different scenes can occur when the change of scenes in the moving pictures is very fast, but the frame buffer's refresh rate does not match the monitor's scanning frequency. In the DVR system, a recently popularized visual monitoring system, the tearing artifacts becomes more serious since the frame buffer's refresh rate is vey high due to the requirement of multi-channel display. In this paper, we propose an improved display system for windows-based DVR systems which prevents the tearing artifacts without daterioration of display speed perfromance. The efficiency of the proposed display system is verfied through experiments.

교정치료와 악교정 수술을 필요로 하는 환자가 점증하는 현 시점에 비추어, 이에 대한 기술적인 측면의 발전과는 달리 수술-교정 치료 환자에 대한 정신사회학적 혹은 정신심리적 양상에 대한 객관적인 정보는 그리 많은 주목을 받는 편이 아니었다. 수술-교정치료는 과학적인 치료과정이긴 하지만, 어느 정도 심미적 혹은 예술적인 측면을 지니는 선택 치료의 면모를 지닌다. 그러므로 치료에 대한 환자의 주관적인 느낌은 치료 기술이나 치료의 의학적 성공 여부보다 더 큰 영향을 미칠 수 있다. 그러므로, 수술-교정 (혹은 교정) 치료에 대한 환자의 반응을 예측하기 위한 정신심리적인 정보는 치료에 유용한 지표가 될 수 있다고 가정할 수 있다. 통제 소재에 대한 연구는 인간의 다양한 행동을 예측하기 위한 유용한 지표로 알려져 왔는데, 본 연구에서는 42명의 수술-교정치료 환자와 성별/연령별로 표본 추출된 42명의 통상적 교정치료 환자를 대상으로 삼아 정신=심리적 비교 및 분석의 방법으로 두 가지 종류의 내외 통제 소재(internal/external locus of control) 검사를 시행하였다. 그 결과 수술-교정치료군에서만 남자가 여자에 비하여 낮은 외적 통제(높은 내적 통제)의 경향을 보였다. 결론적으로 수술-교정치료 환자의 정신심리적 기반은 성형 수술 환자와는 달리 교정치료 환자와 유사한 경향을 지닌 것으로 생각되었다. Surgical-orthodontic treatment is an increasingly more common dental procedure whose unique psycho-social or psychological feature has not been fairly quantified objectively. Since the treatment of a surgical-orthodontic (or orthodontic) patient is part science and part art, a subjective recognition of a patient about his or her own treatment may be more important than technical success during and after treatment. Therefore, the knowledge of the patient''s underlying psychological status could be useful in the prediction of patient's response to surgical-orthodontic (or orthodontic) treatment. The purpose of this study was to investigate and evaluate the psychological difference between conventional orthodontic patient and surgical-orthodontic patient by using locus of control (LOC) examination. Locus of control scale has been proven to be extremely useful in the prediction of a variety of human behaviors. Two types of locus of control data (I-score, Internal locus of control score ; E-score, External locus of control score) were obtained for 42 surgical-orthodontic patients and randomly selected 42 conventional orthodontic patients (as a control group) matched for age and gender. No statistically significant difference was observed in the scale of internal and external locus of control between the groups of surgical-orthodontic patients, males showed lower E-score (external locus of control score, higher internal locus of control tendency) than females. The results of this study suggested that the psychological background of surgical-orthodontic patients, in contrast with that of cosmetic surgery patients, has a similar disposition with that of orthodontic patients.

Cracking is considered to be one of the important factors in determining the durability of reinforced concrete structures. When the bending stress exceeds the modulus of rupture of the concrete, cracking fom along the length of members. The total load is transferred across these cracks by the reinforcement, but the concrete between craks is still capable of carrying stresses due to the bond between steel and concrete. This phenomenon is called the tension stifening effect. The tension stiffening effect is affected by many variables, such as the bond stress, strength of concrete, interrocking of aggregate, type of steel, and dowel action of steel. Also, this tension stifening effect is usually quite significant in beams under service loading, and must be taken into account in the calculation of deflection and crack widths. In this study, the experiment was carried out on types of specimen, strength of concrete, and steel ratio and finite element analysis were compared in terms of load-deflection relationship, crack pattern.

It is necessary to supply external carbon source for enhancement of biological nitrogen removal from domestic wastewater with low influent C/N ratio. Sulfide was chosen as a cost effective electron donor and reaction stoichiometry for autotrophic denitrification was investigated by conducting bench-scale experiments in this study. Higher sulfur to nitrogen (S/N) ratio than the calculated value from theoretical reaction stoichiometry was required when the anoxic reactor was operated at open condition because dissolved oxygen introduced by surface aeration reacted with sulfide with ease. In addition, higher sulfate production and lower yield of microorganism could be observed under the same condition. It was possible to obtain reliable reaction stoichiometry for autotrophic denitrification by establishing pure anoxic condition. Linear relationship between bacterial growth and consumption of nitrate, sulfide, alkalinity, and sulfate production enabled to derive a relatively correct reaction stoichiometry for autotrophic denitrification when sulfide was used as an electron donor.

Splenic abscess is a rare illness. Its incidence has ranged from 0.14 to 0.7 % in various autopsies conducted in the US. Even in the most recently published articles, diagnosis was made only in autopsies in 37 % of the cases. While splenic abscess may arise occasionally from contiguous spread of infection or direct trauma to the spleen, usually it develops with hematogenous spread or infection. But, bacterial endocarditis is the most common cause. RUQ pain of abdomen developed in only half of series. Splenomegaly, fever and leucocytosis was also present. When splenic abscesses are being considered in a differential diagnosis, CT scan of the abdomen has been the most sensitive diagnostic tool. Streptococcal species are the most common bacterial isolates from splenic abscesses, S. aureus is the next most common. Salmonella species are seen commonly in patients with sickle cell hemoglobinopathy. Because of the high mortality related for splenic abscess, the treatment of choice is splenectomy with adjunctive antibiotics. However, percutaneous drainage has been successful alternative. We reported a 19-years old female patient who had splenic abscess after remission induction chemotherapy of acute leukemia, successfully treated with splenectomy.
