1. The purpose of this study is to reflect reality of sports to legal structure. This author classified types of sports related accidents as match accidents, school accidents, leisure and living sports accidents. Out of such accidents common factors such as 'the provider of virtue' and 'user' could be deduced and this author reviewed what kinds of obligations must be shouldered by these people respectively. In particular this author stressed the fact that disproportionate emphasis is placed on malfeasance in disposition of dispute over the sports accidents. Malfeasance is a method for seeking relief through money after the accident. However default in an obligation enables supplementary completion when it is not performed or imperfectly performed. Thus if object which must be performed is providing safety then it is possible to secure safety prior to accident. Furthermore at such time mistake of the debtor can not become a factor. For this reason this line of thinking has the following merits: (1) In comparison with constitution of malfeasance default of an obligation has long prescription. It seems that such fact was a motivation for saving obligation for safety consideration by making it fall under the principle of faith. (2) Default of an obligation is not an obligation for ordinary attention which is cause of malfeasance but it takes up issue with obligation for attention required for performance. Game organization, sponsor and spectators etc. shares certain sense of identity and are demanded to have manners. As method for evaluation of such relationship of faith it may be possible to impose a special kind of obligation for attention and it will be close to constitution of default of an obligation. (3) Imposing obligation for provision clarifies that such responsibility belongs to game organizations promoting sports to which anyone can participates or to national or public organizations, sponsor, schools which induced such sports as a part of its educational programs, installer who made people use it as leisure facility or person in charge for its management. (4) It is also applicable to umpires, players or spectators who use field of sports. It is possible to reflect reality whereby these people specifically relate themselves to sports. In consequence it will be possible to make people feel the necessity of expanding the principals of sports from 'doers' to 'watchers.' (5) The obligation of provision is an obligation under the principle of faith therefore mutual negotiation may be expected to clarify such fact. It may be also evaluated by effectuation of users' self-determining right. 2. If the above mentioned structure is provided then, although it is limited to sports, students who are subjects of instruction, seminar attendants, and furthermore players who finished games may be obligated to bear responsibility for safety consideration under the principle of faith. Accordingly level of relief for considerable number of victims may be increased as cases of treating even borrowed materials as default of obligation being expanded. 3. As scope of responsibility becomes more clearer it will be possible to prevent disputes while securing more safety as rules and regulations become more clearly enacted or new contract is signed or existing contract is revised.

Plasma arc light를 이용한 bracket 부착시의 전단결합강도와 파절양상의 유형

박영철,유형석,오영근,이승연 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.2

본 연구의 목적은 bracket 부착시 광조사시간을 획기적으로 감소시킬 수 있는 plasma arc licht의 임상적 유용성을 visible light 중합시의 전단결합강도와 접착파절양상과 비교해 봄으로써 평가해 보는데 있다. 사람의 상하악 소구치를 포매하여 만든 레진블럭시편에 광중합 접착제인 TransbondR를 사용하여 수종의 bracket을 각각의 조건에 따라 부착한 후 만능 물성시험기를 이용하여 전단결합강도를 측정하고, 접착파절양상을 stereoscope을 이용하여 관찰하여 다음과 같은 결과를 얻었다. 1.Plasma arc light를 이용한 수종의 bracket 접착시 metal bracket과 ceramic bracket의 전단결합강도는 임상적으로 사용하기에 충분한 값을 나타내었으며, resin bracket의 경우 다른 bracket에 비해 전단결합강도가 현저히 작은 값을 나타내었지만 임상적으로 사용이 가능한 값을 나타내었다. 2.Visible light를 이용한 metal bracket의 광중합시 광조사시 간에 따른 전단결합강도는 광조사 시 간에 따른 유의 한 차이를 보이지 않았으며, 임상적으로 사용하기에 충분한 강도를 나타내었다. 3.Plasma arc light를 이용한 수종의 bracket 접착시 접착제 잔류지수를 통해 접착파절양상을 관찰한 결과, metal bracket과 resin bracket의 경우 bracket기저면에 접착제가 반 이상 남아 있지 않은 경우가 많았으며, ceramic bracket의 경우 bracket기저면에 접착제가 반 이상 남아 있는 경우가 많았다. 4.Metal bracket의 부착시 plasma arc light를 2초간 광조사한 군과 visible light를 10초간 광조사한 군의 전단결합강도와 접착파절양상을 비교시 유의한 차이를 보이지 않았다. 6.Plasma arc light를 이용한 광중합시 광조사 거리에 따른 전단결합강도는 거리가 증가할수록 감소하였다. 이상의 실험 결과는 plasma arc light를 이용한 bracket의 접착시 전단결합강도 저하의 우려 없이 임상적으로 사용 가능함을 시사한다. The puruose of this study was to evaluate the clinical usefulness of plasma arc light which can reduce the curing time dramatically compared by shear bond strengths and failure patters of the brackens bonded with visible light in direct bracket bonding. Some kinds of brackets were bonded with the TransbondR to the human premolars which were embedded in the resin blocks according to the various conditions. After bonding, the shear bond strength was tested by Instron universal testing machine and in addition , the amount of residual adhesive remaining on the tooth after debonding was measured by the stereoscope and assessed with adhesive remnant index(ARI). The results were as follows : 1.When plasma arc light was used for bonding the brackets, the shear bond strength was clinically sufficient in both metal and ceramic brackets, but resin brackets showed significantly lower bond strength but which was clinically useful. 2.When metal brackets were bonded using visible light, there was no significant difference in shear bond strength due to the light-curing time and the bond strength was clinically sufficient. 3.When the adhesive failure patterns of brackets bonded with plasma arc light were observed by using the adhesive remnant index, the bond failure of the metal and resin bracket occurred more frequently at bracket-adhesive interface but the failure of the ceramic bracket occurred more frequently at enamel-adhesive interface. 4.There was no statistically significant difference of the shear bond strength and adhesive failure pattern between metal bracket bonded for 2 seconds by curing with plasma arc light and 10 seconds by curing with visible light. 6.When metal brackets were bonded using plasma arc light, the shear bond strength decreased as the distance from the light source increased. The above results suggest that plasma arc light can be clinically useful for bonding the brackets without fear of the decrease of the shear bond strength.

김형락,박종연,김형종 江原大學校 産業技術硏究所 2004 産業技術硏究 Vol.24 No.A

Fine blanking can be considered as a manufacturing process capable of producing sheet metal parts with completely smooth edges that may be hardly obtained by conventional shear-cutting procedures. This fact, together with the considerable economic advantages offered by this process, has been responsible for the rapid acceptance of fine blanking throughout the manufacturing industry all over the world, and the discovery of many new applications. This study was performed to investigate the effect of clearance and V-ring shape on the quality of sheared surface in a fine blanking process. The critical value needed to apply the normalized Cockcroft-Latham fracture criterion to the simulation of fine blanking is obtained by correlating the result of finite element analysis and that of experiment for the uniaxial tensile test. From finite element analysis of an axisymmetric fine blanking process. It has been found that punch load, die-roll depth, burnish zone size and shape of sheared surface are considerably influenced by clearance and V-ring shape.

목적 : 항암화학요법 중 호중구감소증을 동반한 발열이 발생하는 암환자들을 치료하기 위한 다양한 항균제와 여러 가지 방법들이 시도되고 있는 가운데, 합병증과 사망률의 발생가능성이 적은 저위험군 환자들을 대상으로 초기 72시간동안 정주 항균제를 투여한 이후 경구 항균제로 전환하는 요법의 유용성과 안정성을 평가해보고자 본 연구를 시행하였다. 방법 : 1998년 2월부터 1999년 9월까지 본원에서 항암화학요법 중 호중구감소증과 발열이 발생한 환자들 가운데 기저 암질환이 고형암이거나 림프종이고, 입원당시 패혈증의 증후가 없으며 입원 72시간이내에 해열되고 백혈구수치가 증가 추세인 환자들을 대상으로 하여 72시간 동안 정주 항균제를 투여한 이후 경우 ciprofloxacin 750㎎을 하루 2회씩 투여하여 총 4일간 투여하였다. 모든 환자들은 열이 떨어지고 호중구감소증이 회복될 때까지 입원하도록 하였다. 결과 : 총 38명 환자의 40예가 등록이 되었고, 환자들의 기저암 질환은 고형함이 72.5%, 림프종이 27.5%였다. 입원당시 평균 호중구치수는 156/㎕였고, 호중구수치가 100/㎕미만인 경우는 65%였으며, 호중구감소증이 지속된 기간의 평균은 2.4일이었다. 40예 중 39예가 항균제의 변형이나 추가 없이 호중구감소증과 발열로부터 회복이 되어 97.5%의 성공율(95% 신뢰구간: 86.8-99.9%)을 보였다. 부작용으로 피부발진이 있었던 경우가 한 예 있었는데, 증상이 경하여 경구 항균제를 지속할 수 있었다. 심와부의 동통으로 복용을 지속할 수 없어서 대상에서 제외된 예가 또 한 예 있었다. 결론 : 항암요법 중 호중구감소증과 발열을 동반한 환자들 가운데 저위험군 환자들에서 항균제 72시간정주 이후 경구 항균제로의 전환요법은 효과적이고도 안전한 치료방법이라고 할 수 있다. Background : Oral antibiotic therapy following empirical intravenous antibiotics may be effective and safe for febrile neutropenic patients with lowrisk for complications. Methods : We conducted a prospective clinical trial of oral antibiotic therapy in the patients with neutropenia and fever during chemotherapy for cancer. Underlying malignancies were solid tumor or lymphoma with short duration of neurtropenia and the patients had no evidence of clinically or microbiologically documented infections. Oral ciprofloxacin was given to the patients who lacked signs of sepsis on admission, had a rising tendency of neutrophil count (ANC >100 /㎕ ) at 72 hours, and were afebrile at 72 hours. All patients were hospitalized until neutropenia and fever resolved. Results : A total of 40 episodes of 38 patients were enrolled from February 1998 to September 1999. The mean neutrophil counts on admission were 156/㎕ and the mean duration of neutropenia was 2.4 days. The episodes which had neutrophil count below 100 /㎕ were 26 (65%). Treatment was successful in 39 of 40 episodes (97.5% : 95 % confidence interval, 86.8% to 99.9%). Adverse reactions of oral ciprofloxacin were skin rash and epigastric soreness in two cases, respectively. There were no deaths during the study. Conclusions : For low-risk febrile patients with neutropenia during cancer chemotherapy, switch therapy to oral ciprofloxacin at 72 hours following intravenous broad-spectrum antibiotics is effective and safe,

HSDPA 모뎀용 동기추적회로의 설계 및 성능분석

양연실,박형래 한국항행학회 2003 韓國航行學會論文誌 Vol.7 No.1

본 논문에서는 3GPP HSDPA 모뎀용 비동기식 동기추적회로를 설계하고, 설계된 동기추적회로에 대하여 정상상태 지터 분산과 타이밍 에러의 과도응답 특성을 이론적으로 분석하였다. 우선 AWGN 환경에서의 지터 분산을 펄스성형 필터, 타이밍 오프셋, 신호 대 잡음비, 루프 대역폭에 대한 식으로 유도하였으며, 과도응답특성 또한 이론적으로 해석하였다. 끝으로 설계된 동기추적회로의 성능을 컴퓨터 시뮬레이션을 통하여 확인하였다. In this paper, a non-coherent code tracking loop is designed for 3GPP HSDPA MODEM and its performance is analyzed in terms of steady-state jitter variance and transient response characteristics. Analytical closed-form formula for steady-state jitter variance is first derived for AWGN environments as a function of pulse-shaping filter, timing offset, signal-to-interference ratio, and loop bandwidth. Also obtained is the transient response characteristic of a tracking loop. Finally, the performance of the designed tracking loop is confirmed by computer simulations.

혼합용매법에 의한 Mullite 전미분체 생성기구에 관한 연구

황운연,이정운,박형상,김용렬,구기갑 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.4

Si-와 Al-알콕시드의 반응속도 차이를 조절하기 위한 부분 가수분해법과 입자 형태를 제조하기 위한 혼합용매법을 이용하여 구형의 미세한 mullite 전미분체를 제조하였다. Mie 이론을 적용시켜 반응시간에 따른 반응용액의 탁도 및 입자 수밀도의 변화를 측정하여 혼합용매법에 의한 입자 생성기구에 대하여 고찰하였다. 알콕시드와 옥탄올 용액에 아세토니트릴을 첨가하면 알콕시드의 용해도가 낮아지고 따라서 알콕시드의 일부가 액적을 형성하며, 액적은 안정화제 (HPC)에 의하여 구형을 유지하게 된다. 그리고 가수분해 및 축합중합 반응에 의하여 액적의 입자 크기는 감소하며, 동시에 혼합용액에 용해되어 있던 알콕시의 가수 분해 및 축합중합 반응에 의하여 미세 입자가 생성된다. 액적형태로 생성된 큰 입자와 미세 입자의 응집에 의하여 최종 입자가 생성되었다. In this study, spherical fine pre-mullite particles were prepared by partial hydrolysis method to control the reaction rate difference of two alkoxides, and by mixed solvent method to control the particle shape. Based on the adaptation of Mie theory, the formation mechanism of pre-mullite particle in alkoxide-octanol-acetonitile system has been investigated by measuring of the turbidity of solution, the number density and the size of the particles during the reaction. As the acetonitrile was added in the alkoxide-octanol solution, the solubility of the alkoxide decreased. A part of alkoxide was segregated from solution in the form of droplets. whereas the rest of the alkoxide existed as dissolved state in octanol. The droplets are stabilized with stabilizer (HPC). In the next step. hydrolysis and condensation reactions of the alkoxide droplets decrease the size of droplets and, at the same time, fine particles are formed from the alkoxide dissolved in octanol. Subsequently, the final particles are produced by aggregation between the large particles through the droplet form and the fine particles.

Hypereosinophilic syndrome is characterized by persistent blood eosinophilia of 1,500/ul or more in the absence of known causes and multiorgan dysfunction by eosinophil-related tissue damage. In Korea, some cases of hypereosinophilic syndrome with hepatic involvement have been described with prolonged benign clinical courses. Most of them were diffuse or multifocal lesions in imaging studies, and a few case presenting as a single mass has been described. Here we report a case of hypereosinophilic syndrome with hepatic involvement in a 65-year-old man who presented with multifocal mass lesions. By abdominal US and CT scan, multiple, ill-defined nodules were detected in throughout the liver. Liver biopsy revealed severe eosinophilic hepatitis, suggestive of hypereosinophilic syndrome. Hepatic mass lesions improved after steroid administration for several weeks.

김준형,김희정,구남수,김영근,최준용,신소연,박윤선,김연아,김명수,정수진,최희경,송영구,이경원,김준명 대한감염학회 2007 감염과 화학요법 Vol.39 No.2

배경 : Clostridium difficile에 의한 설사(Clostridium difficile associated diarrhea; CDAD)는 임상 경과가 다양하다. 최근에 유럽과 북미에서 C. difficile 감염의 발생률이 증가하고 고전적 치료에 잘 반응하지 않으며 이환률이 증가하였고, 이러한 원인이 새로운 균주의 탄생에 기인한다고 보고되었다. CDAD의 예후에 영향을 미치는 세균성 요인과 숙주 요인을 확인하기 위해 본 연구를 진행하였다. 재료 및 방법 : 2002년 8월부터 2003년 12월까지 CDAD가 진단된 20세 이상인 환자들을 대상으로 후향적 Cohort 연구를 하였다. 세균성 요인을 확인하기 위해 cdt A, cdtB, tcd A, tcd A rep 그리고 tcd B 유전자(binary toxin)를 확인하였다. 설사가 치료 시작 후 11일 이상 지속되거나, 2달 이내에 재발하거나, 수술 혹은 다른 시술이 필요한 경우, 사망한 경우 예후가 좋지 않은 것으로 정의하였다. 결과 : 총 115예에서 toxin을 생성하는 C. difficile가 동정되었으며, Toxin A와 toxin B 모두 양성인 균이 91예, toxin B만 양성인 균이 24예였다. Toxin A 생성 여부가 예후에 영향을 미치지 않았지만, 제산제를 사용한 환자에서 그렇지 않은 환자에 비해 toxin B만 양성인 균이 많이 동정되었다(P<0.05). 예후가 좋지 않은 경우는 39예(33.9%)였고 76예(66.1%)에서 예후는 양호하였다. 단변량 분석에서 70세 이상의 고령, 남성, 증상 발현 후 사용한 항생제의 개수 사용, 증상 발현 후 carbapenem, aminoglycoside, glycopeptide 사용, 당뇨 및 뇌졸중 병력이 있는 경우, 그리고 높은 Charlson index가 불량한 예후 인자로 확인되었다. 그러나 독립적인 예후 인자를 조사했을 때에는70세 이상의 고령(odds ratio=3.378, P=0.009), 증상 발현후 carbapenem 사용(odds ratio 7.210, P<0.001)이 예후에 중요한 영향을 미치는 요소로 확인되었다. 결론 : 70세 이상의 고령과 증상 발현 후 carbapenem 사용이 CDAD 독립적인 불량한 예후인자이다. Background : Clostridium difficile associated diarrhea (CDAD) has a wide range of clinical manifestations. The prognostic factors of CDAD are not fully understood. Materialsand Methods : A retrospective cohort study of 115 patients with CDAD from Aug. 2002 to Dec. 2003 was conducted to evaluate prognostic factors of CDAD. Bacteriologic factors were determined by detecting the binary toxin gene, tcd A, tcd A rep and tcd B gene. Poor prognosis was defined as diarrhea more than 10 days even with classic treatment, recurrence, death, and moribund discharge. Results : Approximately 79% of isolated strains were toxin A+/B+ strains and 21% were toxin A-/B+ strains. There was no difference in prognosis between toxin A+ and toxin A- strains. 39 (33.9%) cases showed poor prognosis and 76 (66.1%) cases showed good prognosis. Univariate analyses revealed that the poor prognostic factors were old age over 70 years old, male, the number of antibiotics used after onset of symptom, the administration of carbapenems, aminoglycosides, glycopeptides after onset of symptom, history of DM and stroke, and high Charlson comorbidity index. Multiple logistic regression analysis identified old age over 70 years old (odds ratio=3.378, P=0.009) and the administration of carbapenems after onset of symptom (odds ratio 7.210, P<0.001) as the independent poor prognostic factors. Conclusion : Old age over 70 and the administration of carbapenems after onset of symptom were the poor prognostic factors for CDAD caused by none-binary toxin producing strains.

정인원,박환규,정연복,김수일,원구연,김교형,신철진 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6

연구목적: 정신보건법에 근거하여 매월 정기적으로 개최된 충청북도 정신보건심판위원회를 통하여 정신질환자의 계속입원치료 청구 심사의 현황과 문제점을 파악하고 개선사항을 지적함으로써 정신질환자의 효율적인 관리를 유도하고 인권남용의 여지를 차단하고자 한다. 방 법: 충청북도 내의 정신의료기관에서 계속입원치료 심사청구서 및 진단서, 보호의무자의 동의서 등을 제출한 정신질환자들을 대상으로 계속입원치료 청구에 대한 승인 여부를 매달 정기적으로 심사하였다. 1년 6개월여동안 심사한 자료를 정리하여 진단 및 보호의무자, 의료보장별 특성과 불승인률 등을 분석하였다. 결 과: 충청북도 심판위원회에 계속입원치료를 청구한 정신질환자는 21차례의 위원회 동안 총 7,981명이었으며, 진단별로 정신분열병은 80.9%, 알콜중독은 8.1%, 치매 등 기타는 11.0%이었다. 또한 보호의무자는 시장 또는 군수가 29.8%, 부모가 26.9%, 형제가 26.1%, 부부가 6.3%, 자녀가 5.9%, 기타가 5.0%로 나타났으며, 의료보장은 의료보호가 73.0%, 의료보험이 27.0%이었다. 이들 중에서 196명이 계속입원치료를 불승인받아서 전체 불승인률은 2.46%이었으며 정신분열병과 알콜중독 환자의 진단별 불승인률은 각각 0.73%와 17.6%이었다. 결 론: 정신과 병상의 대부분이 장기적으로 입원하는 만성 정신질환자들로 구성되어 있어서 이들에 대한 별도의 대책이 시급하다. 또한 계속입원치료가 불승인되어 퇴원한 환자들의 재활 및 사회적응을 위한 사회적 지지 체계가 부족하며, 특히 환자의 인권보호를 위한 구체적인 기준 등이 필요하다. Objectives: This study was to develop effective managements and to avoid the abuse of human rights in mentally-ill patients. The Mental Health Judgement Board of Chungchongbuk-do province has been held monthly since August, 1997 according to the Mental Health Act. In this study, the procedures and the problems of judging continuing hospitalization of chronic mentally-ill patients were reviewed. Methods: The mentally-ill patients who submitted the request for continuing hospitalization with the certificate of charged doctor and the agreement of caregiver were reviewed by the Mental Health Judgement Board of Chungchongbuk-do province. The analysis of the diagnoses, caregivers, medical care systems, and rejection rate for the patients were done. Results: Total mumber of mentally-ill patients who requested for continuing hospitalization were 7,981 from twenty-one monthly meetings. The diagnostic distributions were 80.9% for schizophrenic patients, 8.1% for alcoholics and 11.0% for others including dementia. As for the caretakers, the rate of majors was 29.8%, parents 26.9%, sibling 26.1%, spouse 6.3%, offspring 5.9%, and others 5.0%. And 73.0% of the patients were on Medicaid and 27.0% were insured. The patients who got the rejection for continuing hospitalization were 196 at the rate of 2.46%. And the rejection rates of schIzophrenic and alcoholic patients were 0.73% and 17.6%, respectively. Conclusions: New policies for decreasing longterm hospitalization of chronic mentally-ill patients are required. And the social support systems for psychiatric rehabilitation and readjustment are presently insufficient for the already discharged mentally-ill. Moreover, the practical guidelines for human rights of patients remains to be suggested.
