Recently, Practicing of ghost surgery and duty of informed consent of doctors have become a big issue in the medical dispute and lawsuits. The ground of admitting the informed consent and the agreement(self-determination of patients) can be based on the dignity of man and the right to pursue his happiness guaranteed under Article 10 of the constitution in theory. However there are no explicit legal regulations on the duty of the informed consent and there is no substantive legal enactment on the informed consent, but there is a collision between self-determination of patients and the discretionary power of doctors. If the discretionary power on the duty of the informed consent was extended it may result in the infringement of the right of surgical patients, so called arbitrary medical treatment. Relating to this issue, New Jersey Supreme Court held that a patient has the right to determine not only whether surgery is to be performed on him, but also who shall perform it. Moreover it held that a surgeon who operates without the patient's consent engages in the unauthorized touching of another and, thus, commits a battery'. But there are no ghost surgery cases adopting battery theory in Korea, and professional negligence has been considered rather than the battery, regarding an absence of hostile intent to injure patient. Supreme Court of Korea held that a doctor who operates a medical procedure without the patient's valid prior consent based on wrong diagnosis commits professional negligence resulting in injury, and the patient's invalid consent do not preclude wrongfulness'. However, if a health care provider conducts a completely non-consensual treatment or substitute surgeon without consent, the action should be plead in battery, not negligence, but if a health care provider violate his duty of care in obtaining the consent of the patient by failing to disclosure all relevant information (risks) that a reasonable person would deem significant in making a decision to have the procedure, the action should be plead in negligence, not battery. Therefore, the scope of patients' self-determination can be protected by stating clearly the scope of the duty of the informed consent and the exemption of the informed consent legislatively, it is considered that it is valid to legislate the limitation of the discretionary power.

This study was investigated with denitrification of wastewater containing nitrate using upflow sludge blanket process. Contents of this study were the NO3--N removal efficiency by various hydrogen donor addition, determination of optimum COD/$NO_3^--N$ ratio and characteristics of granular sludge.

One of the important restraint conditions for determination of rotary tiller parameters is whether the outside of front cutting surface on blade in rotary tiller pushes untilled soil in operation. By theoretical analysis and graphic verification on computer, no sil-push conditions is put forward and formula for calculating the position angle of its bent line derived, as is convenient for selection of rotary tiller parameters and design and drawing of its blade.

The end of life problem in the United States has been evolved from the development of concept of brain death over last 50 yr. The invention of ventilator and the development of emergency medicine also played a key role to elongate the end stage of life and which caused the American people to ask a question about the patients self determination and refusing the unwarranted medical treatment in the view of the death with dignity. With regard to the patient unable to self determination, surrogate decision was also considered. To guarantee the self determination, The patient self determination act also enacted on the level of Federal regulation in 1990s. But no law has effectively dealt with the situation when medical treatment became futile. Along with the significant debates on literature and court cases. The American Medical Association's Council on Medical and Judical Affairs presented formal opinion and the Texas was the first states to regulate the medical futile situation in 1999. Even though that definition was in controversy, the concept of medical futility mainly focused on the doctors' right to refuse the treatment.

A new, simple and fast flow injection analysis (FIA) method has been developed for the indirect determination of nitrite. The proposed indirect automatic method is based on the oxidation of nitrite to nitrate using a lead(IV) dioxide oxidant microcolumn where the flow of the sample through the microcolumn reduces the $PbO_2$ solid phase reagent to Pb(II), which is measured by flame atomic absorption spectrometry. The absorbance of Pb(II) are proportional to the concentration of nitrite in the samples. The calibration curve was linear up to 30 mg $L ^{-1}$, with a detection limit of 0.11 mg $L ^{-1}$ for a 400 mL injected sample volume and a sampling rate of about 80 $h ^{-1}$. The results exhibit no interference from the presence of large amounts of ions. The developed procedure was found to be suitable for the determination of nitrite in foodstuffs and wastewaters. A relative standard deviation better than 0.9% was obtained in a repeatability study. The reliability of the method was established by parallel determination against the standard method.

Objective : The present study was designed to compare Global Field Power Measurement and conventional method in P300 determination. Method : The subjects were composed of patients(N=20) with schizophrenia by DSM-IV and normal controls(N=20). The auditory event related potential P300 was measured by "oddball paradigm". P300 components were determined by Global Field Power Measurement and conventional method at 5 electrodes(Fz, Cz, Pz, $T_3$, $T_4$). Results : P300 amplitudes of patients were smaller than those of controls across all electrodes and in both methods, but there was no differential power in P300 determination between two methods. Asymmetry of auditory event-related potential P300 was not shown between patients with schizophrenia and normal controls. Conclusion : It is implicated that it depends on clinical situations and research purposes what method of P300 determination will be more appropriate for patients with schizophernia.
