Wire electrical discharging machining is a non-traditional, thermoelectric process in which workpiece material is eroded by a series of discrete sparks between the workpiece and a tool electrode immersed in a liquid dielectric medium and has been used widely in production, aerospace, medical and virtually all areas of conductive material machining. But the heat-affect layer is produced by the heat under machining. In this study, the variation of surface roughness, hardness and residual stress along the Co-containing amount of tungsten carbide in the same machining condition and along the machining energy in the same Co-containing amount of tungsten carbide are presented experimentally. These are compared to the SEM. In conclusion, the more Co-containing amount, the more surface roughness increases, the hardness decreases and the residual stress is not affected. As a machining energy increases, a Co-omittance increases.

스프링강(SUP9A)과 SM25C의 마찰용접최적화에 관한연구

Friction welding is to jiin two materials by the frictional heat that occurs on the surface area of the two pressurized materials due to their relative motion. The pressurized welding method can be applied to the welding of the same material of different materials. The friction-welded SM25C can be selected as a substitute for the spring steel which is used in the machinery, airplane and automobile, etc. This substitution would provide cost reduction of material and the weight of the welded part. The results showed that friction welding could keep good mechanical properties of the welded part by applying optimum welding condition and proper heat treatment.

This study was conducted to examine the condition of patients with arthritis and its related factors. Data were collected from 100 people who suffered from arthritis in Seoul. Busan, Daegu, Daejun, Junjoo, and pohang from April 2, 2000 to July 31, 2000. The results of this study are summarized as follows : 1. 6L0% of the subjects were female. The incidence rate of arthritis was higher in the higher age group, lower educated group, and thinner group. In case of male, the incidence rate was higher in the groups of single, residents in big cities, and technicians. In case of female, it was higher in the groups of the married, residents in towns or villages, and housewives. 2. According to the parts of arthritis, knee joint covered 67.4% and backspine joint covered 9.0%. The incidence rate of arthritis was higher in the groups of forties, housewives, single, irreligious people, residents in towns and villages, primary school graduates, thin people, and walk exercisers. 3. The arthritis patients felt pain most when they stood up (31.5%). According to the time when they felt pain most, the time when they were active during daytime was 31.5% and nighttime was 29.8%. When they got up in the morning was 22.4%, while 10.9% felt pain all cay long. 4. they had arthralgia knees and cramp in crook of the knees (21.8%). Their knees ticked when they moved (21.1%). The had to rest hands on anyplace when they stood up (18.7%) and they could not completely unfold their knees. 5. The medical institutions which diagnosed them showed significant difference in the variables of sex, age, marital status, religion, place in residence, education level, economic status, obesity level, exercise, parts of arthritis, and posture of feeling pain. from above results, it can be concluded that it is necessary to develop appropriate medical treatment on the basis of the respondents' socio-democraphic characteristics, pain parts, period of having a pain, satisfaction level with treatment and its related factors. Therefore, related professionals and organizations must develop education program for prevention of arthritis in order to educate them.

정제명,왕순주,안무업,박재형,유기철,박준석,강재구,제프리 아놀드 대한응급의학회 1999 대한응급의학회지 Vol.10 No.4

Background : To assess the current level of development of emergency medicine (EM) systems in Asia. Method : Survey of EM professionals from 12 Asian countries during a 90-day period from August to November 1998. 12 EM professionals from 12 Asian countries completed the survey. All participants were physicians. 7 participants (58%) gave presentations at an international EM conference during the study period. Respondents completed a 103 question questionnaire about the status of EM specialty, academic, patient care, information and management systems and the factors influencing the future of EM in their countries. Results : 92% of respondents stated that their countries have hospital-based emergency departments (ED). More than 80% of respondents reported that their countries have EMS systems and ED systems for trauma care and patient transfer. More than 70% stated that their countries have national EM organizations, EM research, national EMS activation phone numbers, ED systems for pediatric emergency care, emergency physician (EP) training in ACLS and ATLS and peer review. More than 60% reported official recognition of EM as an independent specialty status, ED triage systems and systems for customer service. More than 50% reported EM residency training programs, EM journals and EP ability to perform rapid sequence intubation (RSI). 50% reported EP ability to perform thrombolysis for acute MI and 33% reported EP ultrasonography. 92% felt that a lack of funding posed a moderate or great obstacle to the future development of EM in their countries. Conclusions : Many essential systems of EM now exist throughout Asia. In the systems of administration and emergency medical information in many countries, there are some parts to be developed further.

As chromium in urine remains as oxychromic acid ions, chromium was extracted by using ion pair formed with anion exchanger trioctyl methyl ammonium chloride. After then it is noted whether this TOMAC-MIBK method is effective or not for the chromium analysis by using flame method of Atomic absorption spectrometric analysis. The result is as following. 1. Effects of various acids on the extraction of Cr. with MIBK including TOMAC are good in order HNO_(3), H_(2)SO_(4), HCl and its proper concentration of HCl is 0.03M to 0.3M. 2. TOMAC concentration is 20times the molar concentration of Cr. complex in excess. 3. The recovery of Cr. in urine using AAS was obtained 98~104% for TOMAC. This results indicate that the optimized analytical condition obtained could be successfully applied to the quantitative analysis of Cr. in human urine sample using AAS.

Folie a Deux : FOLIE A DEUX IN FRATERNAL TWINS

이정균,이기황,남명석 大韓神經精神醫學會 1968 신경정신의학 Vol.7 No.1

The authors analyzed dynamically and discussed a case of folie a deux manifested as paranoid schizophrenic reaction in fraternal twins. The lives of the twins are just like that of a person. They have never seperated through their lives. They had lain in the mother's womb together, slept under a coverlet, sat side by side in the school and always went around everywhere in pairs. They have hardly had any intimate friends or neighbors, and even when they had a friend, he was not the friend of a twin but of both. It appears that they formed a microsociety, in which close association and free activity occurred sharing their thinkings, feelings, interests, apprehensions and hopes. Through such a life it is expected that they could not grow up independent personalities an their egos could not be differentiated to each individual. And it is probable that the two undifferentiated egos become a whole one and gain safety and satisfaction by their union. It will be very natural that the thought of one partner is transferred to the other through the symbiosis of personality. Most authors emphasize the dominant-submissive relationship between the primary patient and the secondary partner, but we think it is not inevitable in folie a deux. The long intimate association of partners isolated from the society will promote to form the morbid personality structure that is the soil in which delusions may be sown and flourish.

An halophilic bacterium was isolated from food-waste. The isolated strain was Gram-negative, aerobic bacterium. The range of temperature for growth of the isolate were 30-40℃. NaCl concentration for growth of it was 5-15%. The isolate was catalase and oxidase positive and sensitive to bacterium. It showed starch hydrolyzing and acid forming characteristics. The morphological, physiological and biochemical characteristics of the isolate resembled those of the Halococcus sp., therefore it was identified as Haloarcula sp. CH-667.
