본 연구의 조사 대상은 본 원 에서 요오드화 조영제를 정맥으로 투여받고 CT 검사를 시행한 72,910명과 과거 조영제 과민반응을 겪었던 환자 2,798명을 대상으로 후향적 조사를 시행하였다. 나이, 성별, 과민반응 증상, 조영제 과민반응 기왕력 환자 전처치방법, 사용한 조영제 등을 분석하였다. 조영제 과민반응 발생은 여성과 60대 미만에서 발생 위험이 높고 과거 조영제 과민반응기왕력이 있더라도 적절한 전처치 약물 투여, 조영제 성분 변경을 시행하면 과민반응 발생 위험이 감소한다. 조영제 성분별과민반응 발생률은 Iopromide가 유의하게 과민반응 발생률이 높았고, Iohexol과 Ioversol이 낮은 발생률을 보였다. 조영제 과민반응 재발을 예방하기 위해서는 전처치 약물 단독 사용보다 선행적으로 원인 조영제를 재사용하지 않고 다른 성분의 조영제로 변경하여 사용하는 것이 우선적으로 시행되어야 하고 더불어 전처치 약물 투여와 함께하는 것이 재발을 예방할 수 있을 것이다. The subjects of this study were 2,798 patients who experienced hypersensitivity reaction of contrast media among 72,910 who had had iodinated contrast media administered intravenously and CT examination at our hospital. Retrospective survey was conducted with these subjects. Their age, gender, hypersensitivity reaction symptoms, prepare methods for the patients who had previous hypersensitivity reaction of contrast media, and contrast media administered were analyzed. When it came to the hypersensitivity reaction incidence of contrast media, women and patients aged less than 60 had the high risk of the reaction. Even if patients had previous contrast media hypersensitivity reaction, their hypersensitivity reaction incidence risk was reduced as they had an appropriate premedication drug administered and contrast media were changed. Regarding the hypersensitivity reaction incidence rate by contrast media, Iopromide’s hypersensitivity reaction incidence rate was significantly high, whereas Iohexol and Ioversol had low incidence rates. In order to prevent contrast media hypersensitivity reaction recurrence, it is preferentially necessary to change a contrast media to a different one without reuse of causative contrast media, rather than to use a premedication drug only. Along with that, it is necessary to administer a premedication drug.

Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

Directional solidification experiments have been carried out at the solidification rates from 0.5 to 50$\mu\textrm{m}$/s in Mar M-247LC superalloy in which several important liquid properties were estimated by analyzing the interface stability and temperature gradient at the solid/liquid interface. The diffusion coefficient in the liquid was estimated by employing the constitutional supercooling criterion. The temperature gradients changed with solidification rates and latent heat of solidification. The thermal conductivities of solid and liquid could be estimated by heat flux balance at the solid liquid interface.

Objective. The aim of this study was to assess the gender differences in the clinical presentation and treatment patterns between Korean women and men with ankylosing spondylitis (AS). Methods. We retrospectively analyzed the data from extensive clinical assessments of 721 patients (162 women and 559 men) with AS, who were diagnosed at Seoul St. Mary`s Hospital, between January 2000 and September 2009. Clinical data, regarding the disease onset, disease duration, clinical presentations, status of human leukocyte antigen (HLA)-B27, and bone mineral density, were determined using a dual-energy X-ray absorptiometry (DEXA). Finally, we analyzed the medical treatments prescribed for these patients. Results. The ratio of men to women was 3.45:1. Compared to men, women were older at the time of diagnosis, had shorter disease durations, and were diagnosed in earlier stages of the disease. More women had a history of uveitis at diagnosis than men. Back pain was the main presenting symptom, and its prevalence was the same in both genders. Fewer women showed cervical and thoracic axial involvement than men. Initially, more women had wrist and hand pain than men; however, at some point, peripheral arthritis development was equally likely in both genders. Women experienced shoulder pain, during the disease course, more often thanmen. On the other hand, men presented with knee and hip pain more often than women. Sulfasalazine and anti-TNF agents were more often prescribed to women. Conclusion. The presentation and progression of AS showed a difference between women and men. Because of these differences, AS should be considered when a women presents with peripheral arthritis or uveitis in the early stage of the disease.

The dynamic compliance characteristics of a prosthetic foot midgait are very important for natural performance in an amputee’s gait and should be in a range that provides natural, stable walking. In this study, finite element analysis (FEA) and classical laminate theory were used to examine the mechanical characteristics of a carbon-epoxy composite laminate prosthetic foot as a function of variation in the lamination composition. From this analysis, an FEM model of a prosthetic keel, made from the composite material, was developed. The lamination composition of the keel was designed for improved stiffness. The prototype product was fabricated using an autoclave. Vertical loading response tests were performed to verify the simulation model. The results of the experiments were similar to those from simulations below the loading level of the gait, suggesting use of the proposed simulation model for prosthetic keel design.

Objectives: Workplace incivility is experienced by dental hygienists, who perform a variety of tasks and roles in dentistry. Therefore, to enhance the performance of dental and medical institutions, it is necessary to identify dental hygienists experiencing incivility that affects the organizational performance. Methods: Over a two-month period from May 1 to June 30, 2015, dental hygienists from 30 dental and medical institutions in Busan, the North and South Gyeongsang Provinces, Daegu, Seoul, and the Gyeonggi Province were convenience sampled. Data, from a total of 344 participants, were analyzed using the SPSS and AMOS statistical analysis software. Results: Emotional exhaustion had a partial mediating effect on the relationship between patient incivility and job performance, a full mediating effect in relation to job satisfaction, and a partial mediating effect on the association with turnover intention. Meanwhile, emotional exhaustion had a full mediating effect on the relationships between superior incivility and job performance, as well as turnover intention, while a partial mediating effect in relation to job satisfaction. Conclusions: An in-depth review of interventions that can enable a mutually respectful working environment, and promote a healthy culture among dental hygienists in dental and medical institutions is needed.
