This research tries to look into the idea of a country on agricultural basis that belonged to the scholar of Silhak in the age of Chosun, though the idea of a country on agricultural basis of Korea was derived from that of China. Investigating the idea from Yu, Hyong-Won to Chong, Yak-Yong, we can summarize it as follows; (1) Agriculture (Land) is a basis of the people. So it is understood as an important point of politics. (2) The idea of a country on agricultural basis involves the equal distribution of the land and the idea of equal welfare. (3) For the purpose of the equal distribution and welfare the system of Yochon had been designed, which had the character of community in the process of labour, production and distribution.

There are so many reasons why patient selects orthodontic and orthognathic treatment, but most of them want functional improvement. Sometimes patients are not satisfied though functionally improved. It is apparent that they want esthetic improvement too. Satisfaction and happiness are influenced by on self-evaluation, emotional state, expectation and so on. Clinicians have difficulty in estimating and treating the patients by psychological norm. Therefore, we study the relation between orthognathic surgery and aesthetics.

In this paper, we present the access control technique which is one of the essential functions for VOD. As the BISDN widely spreads, need for VOD services will rapidly be increased. Access control technique is needed to allow VOD system to prevent the unauthorized persons from using the unauthorized service. We have implemented the authentication scheme with C language on UNIX. We have used 768-bit RSA signature scheme and MD5 hash function for implementing the authentication scheme.

In this paper, the band pass filter for personal communication services was constructed and designed using λ/4 TEM mode dielectric resonators with a (Zr0.65,Sn0.35)ATi1.04O4.04 ceramic of dielectric constant εr=37.8, Qxfo=48.600 temperature coefficient of resonant frequency rf=7ppm/˚C, and Unloaded-Q (Qo) of λ/4 TEM mode dielectric resonator with inner hole size 0.9㎜ and external size 3㎜ using silver electrode is 354.5 at 1950MHz. For the band pass filter design and construction, the design theory and simulation results of band pass filter using J-inverter theory have been studied. The parameters which are evaluated by design theory are practically applied to the filter construction and the simulation results are in agreement with the measured results after fine tunnings.

Individual identification is an important part in medicolegal field especially in mass disaster. At July, 27, 1989, KAL KE-803 was crashed on landing at Tripoli International Airport, Liba. The plane was caught in fire and sixty eight Koreans were sacrified. The majority of victims were severely charred and injured. The authors examed all dead bodies and successfully identified all the cases through visual, anthropological, odontological, radiological and pathological methods including fingerprint and blood typing.

Background: Recently, patients' demands for emergency medicine are increasing, and most of prehospital medical care, including basic life support, cardiopulmonary resuscitation and triage, are provided by paramedics or emergency medical technicians. Evaluation of the adequacy of prehospital management and triage has become important for improving the quality and the effectiveness of the emergency medical system. Methods: The 202 patients who were transferred by ambulance with paramedics, nurses, or emergency medical technicians to the Emergency Department in Gil Medical Center from July 1, 1999, to September 31, 1999, were enrolled. This study was conducted prospectively by using the emergency physician,s log and newly devised protocols recorded by paramedics or nurses. Results: 1) Male to female ratio was 1: 0.8, and the peak age of the patients were the 4th(18.8%) and 6th decade(15.3%). 2) Of the 202 patients, 84 patients were transferred for trauma and 118 for medical problems. The mean transfer time was 6±1.73 minutes. 3) The validities of prehospital triage and decisions using the trauma severity measure and the disease severity measure, were 33.3% in trauma patients and 57.6% in medical patients.4) The results for the adequacy rate in prehospital management analyzed by using the rate of necessity of treatment. performance of treatment, and adequate treatment were as follows: oxygen supply.38.1/41.6/93.8 ; wound dressing. 19.3/71.8/92.9 ; immobilization of the cervical spine, 15.8/56.3/92.9 ; application of a spinal board. 12.9/42.3/72.7 ; application of a splint, 9.9/50.0/60.0 ; manual maintenance of an airway. 9.9/55.0/63.6 ; and CPR, 4.5/66.7/0. 5) Kind of ALS(Advanced Life Support) were not conducted(peripheral IV, EKG. intubation, medical administration. defibrillation, pacing). The rates of necessity of treatment were as follows: peripheral IV, 40.6%; ECG monitoring, 23.3% ; endotracheal intubation, 8.9% ; medical administration, 8.9% ; defibrillation. 3.5%; and pacing. 1.5% Conclusion: The adequacy of prehospital triage and decisions using trauma and disease severity measures was relatively low. To improve the adequacy of BLS(Basic Life Support) and to increase the performance of ALS(Advanced Life Support), we must create challenges to develop new protocols and to supplement new equipment.

Primary central nervous system vasculitis (PCNSV) is rare, and the diagnosis is difficult to make because of its variable radiologic expressions. Early corticosteroid therapy often is effective. Herein we report the case of a 56-year-old man who had a well-enhanced cystic mass with severe edema in the right frontal lobe, which was initially felt to be a malignancy. Histologic examination of tissue removed at craniotomy revealed that it was a PCNSV. Despite early administration of corticosteroids, a new lesion developed within 3 days. The lesions responded to treatment with cyclophosphamide and corticosteroid.
