Objectives : Obsessive compulsive disorder (OCD) tends to take chronic course as schizophrenia. Researchers reported that OC patients had idiosyncratic sensitivity to threat-related information, while schizophrenic patients were reported to have affec-tive blunting. We hypothesized that there might be a difference in emotional response between OCD and SPR in cronic phase. Methods : Eight different emotional tasks were done by 25 healthy controls, 21 OCD patients and 25 SPR patients. Visual stimuli were made by pairing two words or pictures. Four kinds of emotional stimuli (positive, negative, combined and neutral)were presented to subjects through monitor and they were asked to report their subjective feelings by pushing mouse button, In the combined condition, a pair of positive words (or pictures) and negative words (or pictures) were presented simultaneously. The responses and response time were recorded and analyzed using SPSS 9.0 package. Results : In the negative condition, OCD group didn't show any deficit compared to healthy group. But SPR group showed significantly lower appropriate response rate than healthy group, In the combined condition, OCD and healthy control group Showed 'negativity bias' which SPR group didn't show. In the positive condition, however, OCD and SPR groups did show Significantly lower appropriate response rate than healthy controls. Conclusion : Our results suggested that OCD patients may not have deficits in the processing of negative emotion even in the chronic phase but to have a specific deficit in positive emotion. This result supports the 'threat-relatedness hypothesis' on attentional bias of OCD.

CITIS(Contractor Integrated Technical Information Service) is a contractor's developed service to provide electronic access and/or delivery of contractually required information. CITIS satisfies one of the major CALS objectives to furnish a single-entry point for authorized access to contractor-generated Contract Data Requirement List(CDRL) data. A critical requirement for the practical implementation of the CITIS concept is the ability to access multiple existing heterogeneous databases in a fashion transparent to the CITIS user. In this paper, we will propose a prototype system model for CITIS, and discuss the system architecture of proposed CITIS system as a global information management system for distributed and heterogeneous local information systems. Furthermore, we will discuss about the required server module and using-scenario of proposed CITIS system.

The orbital blowout fracture occurs when a convex object(usually a baseball and a fist) larger in diameter than orbital rim strikes the orbit, increasing intraorbital pressure and producing hydraulic forces in all directions, which explodes the bony margin. The most frequently site of fracture is the bony floor in the region of the infraorbital canal, less frequently medial orbital wall, that is, lamina papyracea. Medial orbital wall fractures are also seen with other types of facial fractures such as frontal, nasoethmoid, and maxillary injuries. With the advent of nasal endoscope, endoscopic intranasal reconstruction has substituted for external approach. We experienced a case of blowout fracture of left medial orbital wall, which was treated with endoscopic intranasal reconstruction method and report this case with the review of the literature.

In this study, methyl orange-loaded alginate beads were prepared and compared to investigate the effect of chitosan on the encapsulation and release of hydrophilic methyl orange in alginate beads. Particle size and encapsulation efficiency of alginated beads were determined. Swelling ratio and disintegration of al-ginate beads were investigated in gastrointestinal environment. Particle size of beads was 1.1-1.5 mm and shape was spherical. Weight of beads was increased depending on the content of chitosan. Content of chitosan affected on the encapsulation of methyl orange. Encapsulation of methyl orange in alginate beads without chitosan was 15%, while encapsulation efficiency was increased with addition of chitosan. Beads were not disintegrated in HCl solution (pH 1.2) within 4 h, with floating and swelling. Swelling ratio of beads was in-creased to 222%. Release of methyl orange from alginate beads without chitosan was up to 70% within 2 h in HCl solution (pH 1.2). When chitosan was added to the alginate beads, release of methyl range from beads was significantly reduced. It is supposed that release of methyl orange from beads is resulted from diffusion and erosion of beads, which is pH-dependent. In condusion, chitosan-alginate beads have potentials to control release of small hydrophilic drugs by the addition of chitosan.

폴리머 콘크리트는 보통 시멘트 콘크리트보다 접착성, 방수성, 내구성 등이 우수하고 경화속도가 빠르며, 압축강도 및 휨강도가 월등히 큰 것으로 알려져 있다. 이에 본 연구는 충전제와 폴리머를 이용한 투수용 폴리머 콘크리트를 개발하여 이의 역학적 특성을 구명하기 위하여 실시되었으며, 결과를 요약하면 다음과 같다. 단위중량은 보통 시멘트 콘크리트에 비하여 작게 나타난 반면, 각 강도는 일부 배합비를 제외하고는 모두 크게 나타났으며, 정탄성계수가 작아서 변형이 크게 일어난다는 것을 알 수 있었고, 투수시험 결과 시간당 투수량이 최고 8.88ℓ/cm²/h로 나타나 투수성능이 양호하게 나타났을 뿐만 아니라, 이를 이용하여 제작된 투수관도 투수성능을 포함한 외압 강도도 크게 나타나, 기존의 투수관 보다 성능이 상당히 양호하다는 것을 알 수 있었다. 따라서, 투수용 폴리머 콘크리트는 농업분야는 물론 각종 건설분야에서 주택단지, 공장 등의 하수 및 오수관, 도로 등의 지하 배수관, 폐수처리용 오수관은 물론 농업용수 배수 및 송수관, 축산시설, 농업시설의 하수관 및 오수관, 농지배수용, 간척지 제염용 등 여러 분야에 이용 가능할 것으로 예상된다. The use of polymer concrete as on alternative to cement concrete products has been increasing because of its superior mechanical properties, chemical resistance, durability, strong adhesion and rapid curing, it is possible to reduce cross section of structure and unit weight of products when the polymer concrete is used in place of conventional materials. this study was performed to evaluate the mechanical properties of permeable polymer concrete using fillers and unsaturated polyester resin. In consequence of this study, the permeable polymer concrete was expected to show excellent performance and external pressure of the pipes made of permeable polymer concrete was more than that of normal poltland cement concrete. Therefore, permeable polymer concrete can be applied to roads, sidewalks, river embankment, drain pipes, conduits, retaining walls, yards, parking lots, plazas and interlocking blocks, etc.

The gray vibrissae of Korean males(n= 189) between 15 and 75 years old and females(n=111) between 15 and 74 years old whop visited the department of otorhinolaryngology, Konkuk university Chungju hospital during 1996 to 1998, were counted for the purpose of estimating approximate age range in individuals of unknown age. The lowest age appearing gray hairs in both sexes was 15-year-old. The Pearson's correlation coefficient in both sexes was 0.490 (p<0.01). The age appearing gray vibrissae in females was slightly earlier than that of males, however, the differences between right and left sides of nasal cavity were insignificant. This method of counting gray vibrissae would be useful to estimate age range in personal identification together with other methods available until now.
