Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.

연구배경: 감염질환은 혈관질환과 함께 당뇨병의 중요한 사망원인의 하나이며, 혈당조절이 불량할수록 감염 빈도가 증가됨은 잘 알려져 있다. 간농양의 발생이 있어서도 당뇨병은 중요한 기저질환 중의 하나이다. 일반적으로 간농양의 가장 흔한 원인균은 Escherichi coli라고 알려져 있으나, 최근 당뇨병을 가진 간농양 환자에서 Klesiella pneumoniae의 검출이 증가되고 있다. 또 최근 연구에 의하면 K.pneumonie가 간농양의 가장 흔한 원인균이며, K. pneumoniae에 의한 간농양은 K.pneumoniae 이외의 균주에 의한 간농양보다 당뇨병과 밀접히 관련되어 있다고 보고된 바 있다. 이에 저자들은 간농양 환자를 대상으로 당뇨병환자의 빈도를 알아보고, 그 원인균 및 특징을 비당뇨병 환자들의 경우와 비교해 보고자 하였다. 방법: 1992년 1월부터 1999년 6월까지 방사선학적 검사 혹은 수술에 의해 간농양이 확인되거나, 경피적 천자나 수술을 통한 배농액 배양, 혹은 혈액 검사에서 원인균이 증명된 182명의 환자를 대상으로 후향적 임상고찰을 실시하였다. 결과: 화농성 농양을 가진 167명의 환자(남:94명, 여:73명)중 당뇨병을 가진 환자는 54명 (남:30명, 여:24명)으로 32.3%를 차지하였다. 환자의 평균나이는 당뇨군에서 62.1 ± 13.4세, 비당뇨군에서는 55.1 ±15.5세로 당뇨군에서 높았으며(p=0.0021), 남녀간의 평균나이 비교 시 두 군 모두 여성의 나이가 의미있게 높았다. 비당뇨군에 비하여 당뇨군의 경우 저알부민혈증의 빈도와 aspartate transaminase가 증가되어있었다. 원인균주는 K. pneumoniae (당뇨군54%, 비당뇨군 39.1%), E. coli(당뇨군 17.5%, 비당뇨군 18.8%), Pseudomonas aeruginosa, Streptococcus viridans, Enterococcus 순이었으며 두 군간의 의미는 차이는 없었으나 K. pneumoniae의 경우 다른 균종에 비해 단독감염의 빈도가 높았다(82.8%). 사망률은 당뇨군에서 16.7%, 비당뇨군에서 7.1%로 당뇨군에서 의미있게 높았으며(p=0.019), 당뇨군에서의 사망환자는 모두 패혈증이 동반되어 있었다. 당뇨환자의 사망군은 생존군에 비해 당뇨병 이환기간이 길고 혼합감염의 빈도가 높았다(p=0.046). 검사실 소견에서는 총 빌리루빈 및 알카리성 포스파타제의 증가가 관찰되어 있었다. 결론: E. coli가 간농양의 주된 원인균이라는 기존 보고와는 달리 당뇨군과 비당뇨군 모두 K. pneumoniae가 간농양의 주된 원인균이었다. 또한 당뇨 유병기간이 길고 당뇨조절이 불량한 환자에서 혼합감염이며 총 빌리루빈 및 알카리성 포스파타제의 증가등과 같은 위험인자가 존재할 경우 사망률이 증가될 수 있으므로 이들 군에서는 적극적인 치료가 필요할 것으로 사료된다. Background: Liver abscesses are commonly associated with underlying disease, particularly diabete mellitus. The number of the liver abscesses caused by Klebslella pneumoniae in diabetic patient has been increased in Korea nowadays. This study was conducted to clarify the clinical presentation and prognostic factors of pyogenic liver abscesses, especially in diabetic patients and to determine the proportion of K. pneunomiae as a pathogen in liver abscess in Korea. Methods: Medical records of 167 patients treated for pyogenic liver abscess from January, 1992 through June, 1999 were reviewed retrospectively in detail. Major Pathogenic organism, clinical manifestations, prognostic factors, the importance of diabetes mellilus as an underlying disease and its effect on clinical features and prognosis were analyzed. Results: Among 167 cases of pyogenic liver abscess, underlying diabetes mellitus was present in 32.3%. The mean age of patients was 62.7 13.4 years in diabetic liver abscess group and 55.1 15.5 years in non-diabetic liver abscess group. Most liver abscesses were cryptogenic in origin or secondary to the billary tree diseases. The clinical presentations among the two groups were not significantly different. When compared to patients without diabetes, patients with diabetes had significantly higher proportions of hypoalbuminemia and elevated aspartate transaminase level. The most common organism of the pyogenic abscess was K. pneumoniae in both groups. Percutaneous drainage of the abscess with appropriate antibiotics was the most commonly used therapeutic modality in liver abscess. The mortality rate of diabetic liver abscess is 16.1 % and 7.1% in nondiabetic liver abscess. Complications, especially septicemla, were found more frequently in patients with diabetes than in patients without diabetes (64.8% vs 28.3%, septicemia : 31.5% vs 9.7%). The factors influencing mortality in the diabetic liver abscess were disease duration, mixed infection, presence of septicemia, elevated bilirubin and alkaline phosphatase. Conclusions: In contrast to prior report that the E. coli was the most common pathogen in liver abscess, we found that K. pneumoniae was the most common organism cultured in liver abscess. Diabetic patients have more complications and higher mortality than patients without diabetes. Early detection and proper treatment are needed to improve the outcome for diabetic patient with liver abscess.

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.

李承務,崔光鎬 연세대학교 대학원 1980 延世論叢 Vol.16 No.2

This investigation on the adsorption of Hg (II) to chelating resin in the fixed bed ion exchange column was carried out to obtain the mass transfer coefficient, and showed by the equilibrium experiment in batch system, that this process was approached to an irreversible reaction, in dilute solution ranging from 1.25×10-7 mol/ml to 1×10-6 mol/ml. Under the irreversible liquid film mass transfer model, kLs was subsequently not only independent of both initial concentration of Hg (II) and amounts of resins, but also proportional to the 0.25 power of the velocity, thereby expressed as following equation; kLS= 0.34 U0.25 This study also brought about another worthwhile conclusion that the irreversible liquid-film mass transfer model in adsorption of Hg (II) would be valid by compared with Selke and Dryden's experimental results, using dimensionless analysis between Reynolds number and j-factor.

李承務,李勝撥 연세대학교 대학원 1976 延世論叢 Vol.13 No.2

Mass transfer coefficients for the external and internal transport were determined for adsorption of alkyl benzene sulfonate, one of the refractory organic pollutants, on the loca granular activated carbon in the agitating vessel and oscillating cylinder which is, so calledl resonant bubble contactor. The experimental results were correlated with characteristic dimensionless groups of system parameter, and then showed that the film transport coefficient in the oscillating cylinder was increased approximately three times that in the agitated vessel. Other experimental results showed that intraparticle mass transport coefficient was proportional to the square root of time in the initial period of adsorption. Finally, the experimental results were suite fit with the theoretically derived equation on the assumption of film and pore diffusion.

While working with the psychiatric patients, Psychiatrists often find cases that need treatments for physical as well as psychiatric illness. In this regard, One hundred and seventy seven patients admitted to the Neuro-Psychiatric Ward of Kyung-Hee Univ. Hospital during the period of the year 1974, through, were studied and the following results were obtained. 1) Out of 177 neuropsychiatric patients, 105 patients were found to have accompanying physical illness. (59.32% of the patients) 2) Out of 105 patients who had accompanying physical illness, 31 were found to have occured during the hospitalizations, 59 were not aware of the physical illness at the time of admission, and 15 knew of the existence of the physical illness at the time of admission. 3) Classification of the physical illnesses reveald 20 cases (19%) of E. N. T. diseases, 17 cases (16. 2%) of skin diseasea, and 10 cases (9.5 %) each of respiratory and eye diseases respectively. 4) Eleven patients for whom treatment of physical illness was considered as more urgent than that of psychiatric illness were transfered to other departments. 5) Eight patients (7.6% of total physical illnesses) were considered to have contagious diseases. 6) Mean duration of hospitalization of the group with physical illness was 45 days, whereas the group without physical illness was 23 days. 7) Among the patients with accompaning physical illness, male outnumbered female at the rate of 72 to 33. 8) No significant difference was found in the eductional level between the two groups of patients. 9) Mean age of the patients with accmpanying physical illness was 34 years old and that of the patients without accompanying physical illness was 30 years old. The authors hope this report to be not only a warning to illegitimate negligence of physical aspect of health in psychiatric practice, but also a preliminary data for further studies of physical illnesses associated with psychiatric illnesses; the influence of physical illness on psychiatric illness, other reciprocal interrelationship between physical and psychiatric illness or it's therapeutic implications.

In general, concrete showed brittle fracture but HPFRCC(High Performance fiber reinforced cementitious composite) showed ultra high ductile behavior in the hardened state, because of the fiber bridging properties. So a variety of experiments have being performed to access the performance of HPFRCC recently. In this study, to develope HPFRCC with high ductility and strain capacity, effects of fiber types and sand volume fraction were investigated. And results of this study were as follows; · HPFRCC reinforced with PVA or hybrid fiber were superior to PP or singleness. · Effect of sand volume fraction on HPFRCC reinforced with PP was insignificant.
