Background and Objectives : Most Korean young men should take a military physical examination. This study attempted to search the social, economical and psychological features of Korean youths who have psychiatric problems in taking the military physical examination. So this study was intended to help decide whether the youths enter the military service or not. Materials and Methods : This study analyzed diagnostic features that were grouped by 7 categories (antisocial and borderline personality disorder group, the other personality disorders group, psychosis group, organic mental disorder group, neurosis group, pervasive developmental disorders group, the other groups). The study was conducted from 1994 to May 1999 at Chosun University hospital with about 143 patients who were issued the psychiatric certificate for military affairs. Results : According to the results of the psychiatric examination, the antisocial and borderline personality disorder group had increased more year by year than the other groups. Classified by the residential distribution, the residents of agricultural areas belonged to the psychosis group more than others. Classified by the job distribution, the antisocial and borderline personality disorder group had more gangsters than the other groups. Also the pervasive developmental disorders group included those Who were without an occupation. Classified by visiting companion, those who were included in the antisocial and borderline personality disorder group and pervasive developmental disorders group used to come alone as compared with the other groups. In the case of those who have experienced psychiatric treatment in the past and who have been treated psychiatrically after being given the psychiatric certificate, the psychosis group comprised more than 50% statistically. In the case of the existence of a tattoo and self-injured scars, the antisocial and borderline personality disorder group has more than the others statistically. According to psychological examination, by measure of validity scale of MMPI, the antisocial and borderline personality disorder group appeared as the inverted V shape that L, K value was low and F value was high. And the antisocial and borderline personality disorder group measured by the Pd, Pa measure. Pd, Pa measure value got higher points than the organic mental disorder group statistically. Conclusion : The number of the antisocial and borderline personality disorder patients’ visits increased at the psychiatric hospital year by year and there were many gangsters or persons without regular occupation in that kind of patients’group. And there were many visitors who came by themselves to the hospital. Also they tended to have a tattoo or self-injured scars. And most of patients didn’t do commuting psychiatric care after receiving the psychiatric certificate. In the aspect of the psychological examination, they were likely to exaggerate their symptoms or disguise having psychiatric trouble intentionally.

We reviewed 26 dapsone intoxication patients who had visited Severance Hospital Emergency Care Center from January 1991 to January 1995 : 13 of them ingested intentionally, but the other ingested accidentally. Among the admitted patients the highest and lowtheest initial value of methemoglobin level is 59.6% & 10.1%. The frequency of symptoms at presentation was following 16 patients complained cyanosis of lip area, 10 patients complained dyspnea, 4 patients complained mental change, 4 patients complained vomiting, 2 patients complained nausea. The inital level of methemoglobin was less than 50% except in one patient. In the view points of total doses of methylene blue used, less than 100mg was used in 9 patients(34.6%) but in one case, amount of 6400mg was loaded. There were 5 patients(19.2%) in September & 4 patients (15.4%) in January. In respect of result, there were 13 discharged cases (50%) for symptom improvement, and 5 mortality cases(19.2%). The transferred cases from Gangwondo account 19 patients(73.1%). All of them is not directly emergency care center visiting patients but transferred patients from remotely located hospitals. Dapsone intoxication results in severe tissue hypoxic symptoms from malfunction of normal hemoglobin thus only with appropriate available doses of methylene blue & activated charcoal, good outcomes will be expected. If aggressive therapy such as hemodialysis is introduced in treatment of severe dapsone intoxication, the outcomes may be slightly improved better than in other supportive care cases.

The many previous publications have shown the advantages of written discharge instruction over verbal discharge instruction on the basis of comparing the functional illiteracy among emergency department patients. Therefore, authors have conducted a study on the efficacy of written discharge instruction over the verbal discharge instruction of two groups: minor laceration and sprain patients. For the purpose of this study, minor laceration is defined as less than 3 ㎝ laceration on the face or head, or less than 5 ㎝ laceration on extremities. And simple sprains were limited to the extremities. A total of 416 patients who visited Yong Dong Severance Hospital Emergency Care Center were the subject of this study during the period of 2 months from Feb. 1. to Mar. 31. 1996. The study was done prospectively, and patients who entered this study were randomly selected. Simple discharge instruction were made prior to the study and patients were given or verbally told the one of two instruction sets by the emergency medicine resident. After reading or hearing the instructions, each patient was asked to answer four specific questions about them. Statistical significance was examined by t-test and p value of 0.05 or less was considered statistically significant. Mean age for verbal and written instructed group were 26.2 and 25.6 years old. There were 262 and 154 patients in verbal and written instructed group, and the mean score was 2.24±1.20 and 3.42±0.52, respectively. The type of injury was divided into laceration and sprain. Laceration group showed mean score of 2.15±1.23, 3.32±0.51, and sprain group of 2.34±1.16, 3.59±0.50 in verbal and written instruction group, respectively. For the patient younger than 13 years old, discharge instruction was given or described to a guardian. Age less than 13 years old group showed mean score of 2.75±1.11, 3.31±0.48 and more than 13 years old group of 2.10±0.19, 3.34±0.53 in verbal and written instruction group, respectively. The result showed statistical significance between verbal and written instruction group of type of injury and age difference. For the future, simplified written discharge instruction may help and improve the patient`s understanding of the proper management of injury.

OFDM should be used for the fourth generation communication for high speed communication. Because of high spectral efficiency and high tolerance to fading channel, OFDM is applied to many high speed wire and wireless communication such as DAB(Digital Audio Broadcast), DVB(Digita1 Video Broadcast), IMT 2000 etc. Inter-modulation, however, is derived from PAR(Peak to Average Power Ratio) of OFDM signals. The paper describes PTS(Partia1 Transmit Sequence) and SLM(Se1ect Mapping) of an existing methods which can reduce PAR. And then this papers proposed the new method that is called "Combine method". The method proposed in this paper is to combine PTS and SLM. As a result of the simulation, Combine PAR method is better than the existing methods.

A planar chromel-alumel multijunction ac-dc converter was fabricated on a LPCVD Si_(3)N_(4)/SiO_(2)/Si_(3)N_(4)-diaphragm, prepared by silicon bulk micromachining, which thermally isolated a bifilar evanohm-heater and the hot junctions of a chromel-alumel thermopile from the silicon substrate. The voltage responsivity, the ac-dc transfer error, and the fluctuation of the output thermoelectric voltage of the converter were investigated. The respective voltage responsivities in air and in a vacuum of the converter were about 3.16 mV/mW and 9.41 mV/mW. The ac-dc voltage and the current transfer errors in air were about ±1.5 ppm and ±0.7 ppm in a frequency range from 10 Hz to 10 kHz, respectively. The fluctuation of the output thermoelectric voltage from 5 seconds to 120 seconds after preheating in air for 5 seconds was about 0.06 % for a heater input of dc 1 V.
