정희진,손장욱,최선주,엄중식,우흥정,천병철,김우주,박승철 대한감염학회 2004 감염과 화학요법 Vol.36 No.4
목적 : 병원근무자에서의 인플루엔자 예방 접종은 병원내에서 인플루엔자 전파를 막기위한 수단으로 적극 권장되고 있으나 매년 인플루엔자 백신을 접종하는 병원근무자들은 소수에 지나지 않는다. 본 연구는 병원근무자들에서의 인플루엔자 예방 접종률을 향상시키기 위한 목적으로 첫째, 백신 접종자에서의 인플루엔자 백신 접종 계기를 알아보고 둘째, 인플루엔자 백신접종의 장애요인을 분석하여 그 문제점을 해결하는데에 목표가 있다. 재료 및 방법 : 서울 1개 대학병원의 병원종사자들을 대상으로 1999년 10월 1개월에 걸쳐 인플루엔자 예방 접종을 하도록 한 후 2000년 3월에 접종군과 비접종군을 대상으로 구조화된 설문지를 이용한 설문조사를 실시하였다. 백신 접종군을 대상으로 백신접종의 동기(que to action), 비접종군을 대상으로는 접종에의 장애요인(barrier) 등을 조사하였다. 이 외에도 양군을 대상으로 인플루엔자에 대한 지식 척도, 인플루엔자 백신으로 기대되는 효과(benefit)등에 대한 설문조사를 시행한 후 정답률을 조사하였다. 결과 : 1) 설문 조사에 응한 총 수는 309명으로 간호사가 60% 이상이었다. 백신접종군은 평균연령, 평균 근무연수가 비접정군에 비하여 유의하게 길었으나 성별, 직종별 분포는 양 군간 차이가 없었다. 2) 인플루엔자 예방 접종의 필요성에 대한 지식정도에 있어 접종군의 934%가 그 필요성을 잘 인식하여 비접종군의 779%보다 유의하게 높았으나 예방 접종이 필요한 구체적 이유에 대한 정확한 이해는 접종군 113%, 비접종군 119%에 불과하였다. 3) 인플루엔자 예방 접종을 받은 의료인들의 행동계기는 ‘감염관리실의 홍보’와 ‘주위사람들의 권유’에 의한 경우가 26.9%, 21.6%로 가장 많았고 본인이나 가족, 친구들을 통한 일종의 감지된 위협 때문에 접종한 경우 31명(186%)의 순이었다. 4) 비접종자들에서 예방 접종을 시행치 않은 가장 흔한 이유는 ‘업무에 바쁘고 시간이 없어서’라는 항목이었으며(37.3%) 특히 의사 집단에서는 이러한 이유가 68.8%로서 압도적으로 많았다. 간호사나 기타 직종에 종사하는 직원들의 경우는 자신의 건강에 대한 확신이 30%내외에 달하였고 예방 접종 자체의 효과에 의문을 갖는 경우도 직종에 따라 6.3-29.7%에 달하였다. 결론 : 병원근무자에서 인플루엔자 예방 접종률을 향상시키기 위해서는 백신 접종의 장애물(효과의 의문, 부작용)을 효과적으로 제거하고 인플루엔자 백신의 필요성과 효과를 인식시키기 위한 교육과 함께 시간, 공간상의 제약을 배제할 수 있는 접근성의 문제를 해결하여야 할 것으로 사료된다. Background : In spite of yearly recalls, influenza immunization rate among healthcare workers (HCWs) remained low in Korea University Guro Hospital. This study was conducted to identify the causes of non-compliance against influenza immunization and to analyze the barrier factors for the immunization. Materials & Methods : Questionnaires were distributed in March of 2000 at Korea University Guro Hospital. We evaluated factors associated with acceptance of influenza vaccination and opinions regarding influenza prevention (knowledge about influenza vaccination efficacy, que to action in vaccinee, perceptible benefit, barrier to vaccination). Results : 309 completed questionnaires from HCWs were returned. Mean age and mean duration of work in hospital were higher and longer among vaccinee than non-vaccinee. Even though the necessity of influenza vaccination among HCWs were accepted well in vaccinee compared to nonvaccinee, the accurate reasons for vaccination were not quite understood among HCWs regardless of compliance. Vaccine campaign (30.8%) and advise from doctors (24.7%) were important for the promotion of vaccination among vaccinee. However, major reason for non-compliance among nursing staff and was mis-confidence that their bodies' self defense mechanisms would ward off infection (33.5%) and 'too busy to get injection' for doctors (65%). Conclusion : We conclude that regular education about perceptible benefits and wrong concerns about influenza vaccination among HCW's and easy accessibility to vaccination were important determinants to improve the influenza vaccination. On-site availability of a vaccination-nurse also proved to be important.

고기채,선주형,손흥기,고인태 경희대학교 체육과학연구소 2001 體育學論文集 Vol.29 No.-
The aim of the study was to provide useful basic materials for researches into the ways to enhance volleyball referees' attention. The attention power test(TAIS) was carried out by 85 questionnaire papers, three of them were excluded for unfaithfulness and no reply, returned from the referees who participated in the 2001 Samsung Fire Insurance Super league, the 18th Seoul youth athletic meeting combining a preliminary match of Seoul for the 30th National Youth Sports Meet, and the 4th Songwon cup national man's and woman's volleyball game and the test were examined according to the age of referees(the twenties, the thirties, the forties, and the fifties), the types of the certificates(the international. the A grade, the B grade, and the C grade referees), the positions(the 1st, the 2nd, and the linejudges), and the level of concentration skill(the superior, the middle, and the inferior). The results of the comparative verification are like follows. 1) The result of the study on the attention power according to the types of the referees' certificates shows a significant difference at the level of p〈.05. 2) The result of the study on the attention power according to the referees' positions shows a significant difference at the level of p〈.01. 3) The results of the study on the shape of attention power according to the referees' age shows significant differences at the level of p〈.01 in each of BET, BIT, and OIT. 4) The result of the study on the attention power according to the types of the referees' certificates shows a significant difference at the level of p〈.05. 5) The result of the study on the attention power according to the referees' positions shows a significant difference at the level of p〈.01 in BET. 6) The result of the study on the attention power according to the referees' level of concentration skill, divided into the superior, the middle, and the inferior, shows a significant difference at the level of p〈.001. 7) The results of the study on the attention power according to the referees' level of concentration skill, divided into the superior, the middle, and the inferior, shows significant differences at the level of p〈.01 in each of BET, BIT, and OIT and at the level of p〈.05 in NAR. From the results like above, the attention power patterns to be considered for volleyball referees suggest that a attention power pattern is requested with considerations of a factor needed attention in a very active and speedy game situation and a factor concentrating his attention on one affair.

만성질환자에서 인풀루엔자 예방 접종의 효능 분석 : 후향적 환자-대조군 연구
박승철,정희진,손장욱,최선주,엄중식,우흥정,천병철,김우주 대한감염학회 2004 감염과 화학요법 Vol.36 No.4
목적: 인플루엔자는 예방접종을 통하여 효과적으로 예방이 가능한 대표적인 호흡기 감염질환이다. 미국이나 국내의 인플루엔자 예방접종 지침에서 고령인구(50세 또는 65세 이상)와 그 외의 만성질환자들을 인플루엔자 예방접종의 일차 대상자로 정하고 있다. 그러나 국내에서는 아직까지 만성질환자들에서의 인플루엔자 백신의 효능평가에 대한 연구결과가 없는 실정이며 국내에서의 만성질환의 분포가 외국의 그것과 일치하지 않기 때문에 본 연구에서는 국내 만성질환자들에서 인플루엔자 예방접종과 연관된 병원입원율의 차이를 비교해 보고자 하였다. 재료 및 방법 : 1999년 11월-2000년 3월(5개월간) 서울 소재 2개 대학병원에 입원한 만성질환자중 발열과 호흡기 증상이 있어 인플루엔자 또는 인플루엔자양 질환이 의심되거나 그로인한 만성질환의 악화로 추정되는 환자군과 이를 배제한 대조군을 중심으로 혈중 인플루엔자 항체가를 조사하였고 인플루엔자 백신접종력을 조사하였다. 결과의 해석은 로지스틱 회귀분석을 이용하였다. 결과 : 만성질환자를 대상으로한 환자 대조군 연구에서 2개 대학병원에서 1년간 조사한 결과 항체 검사에 기준하여 최종적으로 환자군 64명, 대조군 117명이 포함되었다. 환자군에서는 대부분이 호흡기질환(253%)과 심혈관계질환(313%)였던 반면에 대조군은 암(466%)이 가장 많았고 심혈관계질환과 호흡기계질환은 각각 134%, 60%로 낮았다. 또한 두군간에는 예방접종의 경력에서 통계적으로 유의한 차이를 보였으며 이때의 비차비(OR)은 0328로서 인플루엔자 예방접종의 입원 예방효능은 672%이었다. 결론 : 만성질환자, 특히 만성 심폐질환들에서의 인플루엔자 예방접종은 불필요한 입원을 줄이는 효과가 관찰되었다. 따라서 의료인들은 고위험군의 환자들에 대하여 인플루엔자 에방접종을 적극적으로 권장하고 실천하여야 하겠다. Background : Influenza is one of the preventable respiratory disease by annual vaccination. Elderly people and patients with chronic medical disease are the primary target for influenza vaccination according to ACIP (Advisory Committee on Immunization). This study was done to determine whether influenza vaccination affects hospitalization due to influenza like illness or it's related complications among chronic ill patients. Materials and methods : Retrospective, case-control study was conducted for 5 months (Nov. 1999-Mar. 2000). Physicians from two-university hospitals in Korea were instructed to collect clinical data, sera from subjects presenting with a flu-like illness or flu-related exacerbation in patients with chronic underlying diseases. We compared the vaccination history of case patients with control. Logistic regression analysis was used to calculate the odd ratio and efficacy of influenza vaccination. Results : Hospitalization due to ILI (influenza like illness) or it's related complications were observed more frequently in patients with chronic lung disease (25.3%) and chronic cardiac disease (31.3%) compared to others. Influenza vaccination resulted in fewer hospitalization with ILI or ILI-related acute exacerbation of underlying disease in chronic ill patients (adjusted odd ratio, 0.328 [CI, 0.14 to 0.73]) during influenza seasons. Conclusion : For patients with chronic disease, influenza vaccination is associated with substantial health benefit including fewer hospitalization. Health care providers should take advantage of all opportunities to immunize these high-risk patients.

B${F_2}^{+/}_{11}^+$MIXED ION IMPLANTATION FOR P+ SHALLOW JUNCTION FORMATION
Sohn, Sohn, Yong-Sun,Ra, Ra, Geum-Joo,Na, Na, Shang-Goon,Lee, Lee, Dong-Ho,Kim, Kim, Chung-Tae 한국재료학회 1995 Fabrication and Characterization of Advanced Mater Vol.2 No.e4
A new method of forming shallow $P^+$-N junctions was studied by using ${BF_2}\;^{+}\;&\;_{11}B^+$ mixed ion implantaion at various mixing ratios. Mixed $P^+$ implantation enables us to control the defect profiles including the depth of A-C(amprphous-crystalline) interface, the depth density of residual dislocation loops as well as the amounts of fluorine-related cluster formation without varying the total dose of boron implanted. The residual defect density of 1.0E15 ions/$\textrm{cm}^2BF_2 \; ^+$ + 2.0E15ions/$\textrm{cm}^2\; _{11}B^+$ implanted sample was reduced about 1/3 of conventional 3.0e15ions/$\textrm{cm}^2 BF_2 \; ^+$ ion implanted one. The depth of residual defects was 13nm shallower than that of conventional $BF_2 \; ^+$ implantation with no increase in junction depth and no deterroration of electrical properties.

BACKGROUND: Left atrial (LA) strain is a novel parameter of LA function. However, its reference value has not been established, and the determining factors for LA strain remain elusive. We aimed to present LA strain with reservoir, conduit, and contractile components and associated parameters in a large-sized group of healthy individuals. METHODS: The present study was from a prospective multicenter registry in South Korea. Subjects who had no history of cardiovascular disease with adequate images were eligible for inclusion. LA reservoir, conduit, and contractile strains (LASRES, LASCD and LASCT, respectively) were measured. Left ventricular global longitudinal strain (LV GLS) and early and late diastolic strain rates (DSRe and DSRa, respectively) were also evaluated. RESULTS: Among a total of 324 subjects (mean age: 49 ± 16 years, 167 females), the mean LASRES, LASCD, and LASCT values were 35.9% ± 10.6%, 21.9% ± 9.3%, and 13.9% ± 3.6%, respectively. Mean LV GLS was -20.4% ± 2.2%, and mean DSRe and DSRa were 1.6 ± 0.4 s-1 and 0.8 ± 0.3 s-1, respectively. With aging, LASRES and LASCD showed significant decreases. Factors showing independent associations with LASRES were age (B = -0.425, p < 0.001), DSRe (B = 4.706, p = 0.001), and LV GLS (B = -1.081, p < 0.001). Age (B = -0.319, p < 0.001), DSRe (B = 4.140, p = 0.002), DSRa (B = -3.409, p = 0.018), and LV GLS (B = -0.783, p < 0.001) showed associations with LASCD. With LASCT, only DSRa showed a correlation (R = 0.277, p < 0.001). CONCLUSIONS: We presented LA strain in a large-sized group of healthy subjects. Age is a significant determinant of LA function. Associations of LA strain with diastolic strain rates and LV GLS reflect cardiac mechanics.
