        Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

        Inconel 718 상향 엔드밀링시 절삭력에 미치는 공구형상오차의 영향

        이영문,양승한,장승일,백승기,김선일,이동식 한국공작기계학회 2002 한국생산제조학회지 Vol.11 No.5

        In an end milling process, the undeformed chip section and cutting forces vary periodically with the phase change of the tool. However, the real undeformed chip section area deviates from the geometrically ideal one owing to the cutter runout and tool shape error. In the current study, a method of estimating the real undeformed chip section area which reflects the cutter runout and tool shape error is presented during up-end milling processes of Inconel 718. The specific cutting forces, K_r and K_t are defined as the radial and tangential cutting forces divided by the modified chip section area, respectively. Both of the K_r and K_t values become smaller as the helix angle increases from 30˚ to 40˚. Whereas they become larger as the helix angle increases from 40˚ to 50˚. The K_r and K_t values show a tendency to decrease with increase of the modified chip section area.

        이진수,김은실,정문현,백제중,정선화,안주희,최영화,이선희,고철우,김성범,김민자,박승철,기현균,송재훈,최상호,김양수,이상오,조용균,박영훈,정숙인,김연숙,이흥범,손창희,장성희,정희진,김우주 대한감염학회 2004 감염과 화학요법 Vol.36 No.3

        목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

        Ⅲ급 부정교합의 수술-교정 치료시 상악 소구치 발치가 치열궁 폭경 변화에 미치는 영향

        이신재,홍성준,김영호,백승학,서정훈 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.1

        본 연구에서는 Ⅲ급 수술-교정 치료 방법에 영향을 미치는 치열 상의 요소를 파악함으로써 술전 교정시 상악 소구치 발치와 비치의 판단에 필요한 임상적 정보를 얻고자 골격성 Ⅲ급 부정교합 환자의 수술-교정 치료시 흔히 선택되는 상악 제1소구치 발치로 치료된 군과 비발치로 치료된 군 간의 치료전/후 상/하악 개별 치아 이동 양상과 치열궁 폭경의 변화 양상을 비교 분석하였다. 이를 위하여 비발치로 Ⅲ급 수술-교정 치료를 마친 환자 (24명) 와 술전교정 치료시 상악 제1소구치가 발치된 환자 (31명) 의 치료 전/후 모형 상에서 개개 치아의 근원심/협설측 각도변화와 상/하 치열궁 폭경의 변화를 측정한 후, 두 군 사이의 교정적 치아 이동 양상을 비교 분석한 후 상/하 치열궁의 조화를 이루는데 필요한 치열궁 폭경의 변화와 이에 기여하는 치아 변위와의 관계를 분석하기 위하여 상관 분석과 회귀 분석을 시행한 결과 발치 군은 비발치 군에 비하여 상악 치열궁 폭경의 감소가 컸으며, 이는 상악 구치의 inclination 감소에 크게 영향 받은 것으로 관찰되었다. 하악 치열에서는 inclination의 증가와 폭경의 증가가 있었으나, 비발치/발치군간의 차이는 유의하지 않았다. 본 연구의 결과 결론적으로 Ⅲ급 수술-교정 치료시 술전 상악소구치 발치는 상악 구치부 치열궁 폭경의 감소에 크게 영향을 미치므로, 상악 소구치 발치에 대한 판단은 상/하악 치열궁의 폭경 및 구치부 경사도 문제와 연계하여 고려해야 할 사항으로 생각되었다. Collective changes caused by orthodontic tooth movement evaluated in a specific treatment modality could give suggestive information on the specific treatment strategy. The aim of this study was to investigate retrospectively the characteristics of the orthodontic tooth movement during surgical-orthodontic treatment in order to provide an effective presurgical orthodontic treatment planning for the maxillary premolar extraction modality in the skeletal Class Ⅲ malocclusion patient. Pre- and post-treatment dental casts of skeletal Class Ⅲ malocclusion patients with nonextraction (N=24) and the maxillary premolar extraction (N=31) were collected. The angulation and inclination measuring gauge (Invisitech Co. Seoul, Korea) was used to evaluate the orthodontic tooth movement. The changes in the maxillary and mandibular dental arch widths were also measured from the canines to the second molars. As a result, more palatal Inclination change in the maxillary dentition was found with the premolar extraction modality than with the nonextraction modality. Linear regression analysis showed that the inter-arch width coordination was mainly due to the inclination changes of maxillary posterior teeth. We conclude that the indications and proper treatment planning for surgical-orthodontic treatment in skeletal Class Ⅲ malocclusion with maxillary premolar extraction could depend partly on the magnitude of the transverse inter-arch coordination especially in the maxillary dentition.

      • 한국 미생물 자원의 개발연구 : 특히 유용 미생물주(균주)의 분리와 응용에 관한 연구 The Research on the Isolation and Application of Utilizable Microorganisms Related to Jeonju Materials

        이주식,백승화,이오형 Natural Science Research Institute JEONJU UNIVERSI 1987 전주대학교 자연과학연구소 학술논문집 Vol.2 No.2

        The isolated strains of microbes from some hay, water of lake, marketing milk and Tachju brewing in Jeonju area. Were as follows Isolated 10 strains of Bacillus group, 2 strainins of Chlorella group, 2 strains of Lactobacillus group, 2 strains of Saccharomyces grpup and other microbes and determinated 4 strains in the 20 strains and application of utlizable microorganisms studies on the strains or pure cultual materials. Microbiological and biochemical examined for each organism. Its Bacillus species, Lactobacillus species, Chlorella species and Saccharomyces species were as follows. Bacillus species in Bacillus subtilis natto like strain. In addition, some of these strains were prepared to show different responses to the biotin added medium. Therefore our primary purpose was to examine the possible effects of glutamic acid, biotin and boiling soybean extract on the growth or sporulation of one these strains. It is a novel finding that biothin and soybean extrat affects on its sporulation. Glulamic acid was required for both its growth and sporulation. Chlorella species is Chlorella ellipsoidea like strain. The optimum cultural conditions and composition of the medium for wild Chlorella ellipsoidea were studies as follow. The addition than in control in concentration of the nitrogen sources high presented the effective result in the increasing order of meat extract, peptone amino, acid. Lactobacillus species is Lactobacillus casei like. Lactobacillus casei was isolated relatively high temperature and high salt contend and mesothermophilic condition. In addition, among, J-1, J-2, J-3 strains isolated together from above samples, J-2 was prominant in producing typical curd within 20 hours. Saccharomyces species is Saccharomyces cerevisiae like. When Sacchromyces cerevisiae like was used as a sole yeast source, this was dominated soon after it. But in this case Hansennula, Candida, Pichia, Torulopsis etc. were alse found out. This fact indicates that many kinds of yeast species were related with the alcohol fermentation. Biochemical studies on Cell-bound a-amylase in Bacillus subtilis like. Extracelluiar and Cell-bound a-amylase were purified separately and some of their biochemical properties examined. The amount of extracellular a-amylase produced by bacteria is known to very greatly with growth conditions. Extracellular a-amylase activity was more inhibited than cell bound a-amylase by metal ions tested.

        Fluoride, Bisphosphonate 및 Gallium이 상아질 흡수 억제에 미치는 영향

        백은영,유윤정,노병덕,최윤정,이승종 大韓齒科保存學會 1997 Restorative Dentistry & Endodontics Vol.22 No.2

        Replacement resorption is followed by the delayed replantation of an avulsed tooth. Currently no effective treatment is substantiated for replacement resorption. The purpose of this study was to investigate the effect of stannous fluoride, bisphosphonate(etidronate disodium) and gallium nitrate, which have been shown to reduce dentin resorption, on human dentin. Osteoclasts were collected from tibeas of chich embryo. The cells were well agitated to prevent adhesion and seeded onto the sliced human dentin wafers which had been soaked in either culture media(control), or several different concentrations of stannous fluoride, etidronate disodium(1-hydroxyethylidene-1, 1-bisphosphonate disodium), and gallium nitrate. Resorption was measured by counting the number of resorptive pit produced by the cells. Results are ad follows. Stannous fluoride and etidronate disodium showed statistically significant reduction of dentin resorption(p<0.05) but the effect of stannous fluoride seemed to be its high cytotoxicity. Etidronate disodium did not show cytotoxicities in all experimented concentrations. Gallium nitrate did not show differences in resorption either between different concentrations of from the control group.

        수술-교정 치료 환자의 통제 소재

        이신재,안석준,백승학,김태우,장영일,양원식,서정훈,남동석 대한치과교정학회 2002 대한치과교정학회지 Vol.32 No.4

        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.

        이진경,민선홍,홍성태,오소람,정신혜,황영혜,유성엽,배광식,백승호,이우철,손원준,금기연 대한치과보존학회 2009 Restorative Dentistry & Endodontics Vol.34 No.2

        This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte(NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks As a control. Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE^(*) color difference) was measured using Shadepilot™ (DeguDent) before, during and after bleaching (2 weeks, 4 weeks and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained. 1 Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2 No significant differences were found between the two group (p>0.05) implying that the two agents have a similar whitening effect. 2 The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value thus yellow shade than the control(p < 0.05) 3 None of the participants complained of tooth hypersensitivity or soft tissue complications confirming the safety of both whitening agents 8.3%의 carbamide peroxide를 함유한 펜형 코팅용 미백제인 BlancTis Forte (NIBEC, Seosul & JinCheon)를 실험군으로, 3% hydrogen peroxide를 함유한글 Whitening Effect Pen (LG. Seoul) 제재를 대조군으로 각각 피험자 20명에게 2시간씩 1일 2회 제조사의 지시대로 치아표면에 4주간 적용하도록 지시하고 색조개선 효능과 안전성을 평가하였다. 미백 효과는 미백 전 및 미백 2주, 4주 및 미백 종료 4주 후에 Shadopilot™을 이용하여 색 변화를 측정하였고, 매 내원시기마다 모든 환자는 치수생활력 검사와 치주 및 치태 검사를 통해 부작용 여부 (치아과민증 및 구감 내 연조직의 부작용)를 기록한 후 다음과 같은 결과를 얻었다. 1.실험군 및 대조군의 색 변화량 (ΔE)은 2이상으로 인지할 수 있는 색 변화를 보였으며, 두 제품 간에는 통계적으로 유의한 차이를 보이지 않아 (p > 0.05) 유사한 미백효능을 나타냄을 알 수 있었다. 2,미백효과는 명도의 개선보다는 주로 a. b값의 변화에 의한 것으로 특히 실험군에서 b값의 변화, 즉 황색조의 개선효과가 대조군에 비해 유의성 있게 높은 것으로 나타났다 (p <0.05). 3.치아나 치은의 과민증이나 이상증상을 호소하는 피험자는 없어 두 제품 모두 안전성을 확인할 수 있었다.
