Background Disputes regarding medical malpractice occur between practitioners and patients. As patients have become increasingly aware regarding medical care, an increase in the unexpected side effects of procedures has been observed, thereby leading to an increase in disputes regarding medical malpractice. In this study, we reviewed trends in precedents involving cosmetic surgery-related medical disputes, with the goal of helping to prevent unnecessary disputes in the future. Methods We conducted a search of the judgments made in South Korean courts between 2000 and 2013 that were related to the field of plastic surgery. A total of 54 judgments were analyzed, and the selected precedents were reviewed and classified according to the kind of negligence involved. Results The claim amounts ranged from under 8 million KRW (6,991 USD) to 750 million KRW (629,995 USD). The most common ratio of the judgment amount to the claim amount was 20%-30%. The judgments were classified according to the following categories: violation of the duty of explanation in 17 cases (29%), violation of the duty of care in 10 cases (17%), violation of both duties in 20 cases (35%), and no violation of duty in six cases (10%). Conclusions Cosmetic surgery-related suits require different approaches than general malpractice suits. The Supreme Court requires plastic surgeons to determine the type, timing, methods, and scope of their treatments when considering possible results. Therefore, practitioners should be educated on their rights and responsibilities to enable them to cope with any possible medical dispute that may arise.

This study was conducted to investigate the effects of electric current stimuli and high-voltage electric field treatments on brown rice germination. The brown rice stimulated by electrical current stimuli, functional electrical stimuli of a pulse type, and high-voltage electric field treatments were observed (Type I, II and III). Treatment Type I was a method of semi-soaking brown rice with electric current stimuli of 0.13 V/cm, 0.19 V/cm, and 0.25 V/cm into Petri-dishes for 72 hours. Type II was a method of semi-soaking brown rice with functional electrical stimuli of a pulse type(DC 1 V, 1 Hz, 5%, and duty cycles of 5%, 20%, and 35%) into Petri-dishes for 72 hours. Type III was a method of water-soaking with high-voltage electric field treatments for 60 hours. High-voltage electric field treatments at 15 kV/cm were also conducted for 2.5 min, 7.5 min, and 10 min, respectively. The germination rate and the sprout growth of brown rice germinated by electric current stimuli with 0.13 V/cm, 0.19 V/cm, and 0.25 V/cm were increased by about 10-15% compared with those of the control group. The germination rate and the sprout growth of brown rice germinated by functional electrical stimuli of pulse type(DC 1 V, 1 Hz, 5% duty cycle) were increased by about 10∼15% compared to those of the control group. Also, the best effective treatment among high-voltage electric field treatments was the 10 min group at 15 kV/cm. The germination rate and the sprout growth of brown rice germinated by this treatment of 10 min at 15 kV/cm were increased by about 10∼20% compared to those of the control group. The treatments of electric current stimuli and high-voltage electric field accelerated the germination rate and sprout growth of brown rice by about 10∼15% compared to those of the control group.

This study attempted to examine how we really think about our daily duties, work, and labor, and what it means. In particular, in this study, using the Q-methodology, one of the "qualitative studies," diagnosed and categorized general workers' thoughts about their work and labor. Accordingly, the following analysis results were derived. First, as a result of the analysis, three types were derived, and the types were named as follows based on the Q statement emphasized by each type. emphasizes statements such as 'blessing/happiness', 'rest', 'lover', and 'reward' for work, and labor was named 「Positive Type」. was named as 「Negative Type」 because statements such as 'painfulness', 'the beginning of the day', 'duty', and 'war' were emphasized. In , 'colleagues and friends' and 'learning' were positive, and 'beginning of the day', 'duty', and 'rest' were expressed as negative statements, so it was named as 「Positive Neutral Type」. 'Work' and 'labor', which are indispensable beings in our daily life, are blessings that must be done, happiness, and co-workers and friends, but the value of their existence is possible when appropriate 'resting' is assumed. In addition, Q methodology is expected to be confirmed as an empirical study in the future, as well as usefulness as a hypothesis abductive approach.

Particulate matters (PM) that is generated by most diesel engine is regulated by the mass concentration measured by the conventional method it had been. Recently, Europe PMP (Particle Measurement Program) decided to start the regulation of vehicle's nano-sized particle number (PN) from the year of 2011 because of nano-particle's higher degree of harm to the human body. So firstly, the standard level of PN emission is introduced in the Euro 5/6 emissions regulation with a limit of $6{\times}10^{11}$ per km for light duty vehicle. Also KPMP(Korea Particle Measurement Program) was organized to copy quickly international technical trend. In this paper, it was investigated the nano-sized PN measurement characteristics for different particle generators between spray type and soot type. And the difference ratio between particle generators, the characteristic of PN concentration, counting efficiency and linearity was analyzed. Then, we make conclusions as followed. When particle diameter is increased, counting efficiency of two generators is decreased. Also Secondary calibration method is more higher 3% than Primary calibration method. Finally, SOF which is included in soot particles is not totally removed so it have great influence on test result of counting efficiency and linearity.

Conventional single-phase series quasi Z-source voltage compensator can not compensate for voltage sag less than 50% that frequently occurs in the industrial field. In this study, single-phase series quasi Z-source voltage sag-swell compensator which can compensate the voltage variation of entire range is proposed. The proposed system is composed of two quasi Z-source AC-AC converters connected in series with output terminal stage. Voltage sag less than 50% could be compensated by the intersection switching control of the upper converter duty ratio and of the upper converter duty ratio. Also the compensation voltage and its flowchart for each compensation mode are presented for entire sag-swell region. To confirm the validity of the proposed system, a DSP(DSP28335) controlled experimental system was manufactured. As a result, the proposed system could compensate for the voltage sag/swell of 20% and 60%. Finally, voltage compensation factor and THD(Total Harmonic Distortion) according to voltage variation and load change were measured, and voltage quality shows a good results.

For the purpose of obtaining a fundamental data which is needed to develope the port injection type charged LPLi engine system, we manufactured intake port injection system of liquid charging LPG and modified heavy duty single cylinder LPLi engine from heavy duty diesel engine. Engine output and emission characteristics were analyzed under variable air/fuel ratio and charging pressure. Since LPG is consisted of propane and butane, we investigated combustion characteristics using this two kinds of fuel. From the result of charging engine performance test, engine torque increase about 30% ∼ 40% with 0.3bar charging pressure. In low speed condition, as charging pressure increase, combustion stability improve ill lean bum condition, but, in high speed condition, combustion stability make worse in lean bum condition. We know that engine output decreased rapidly from the condition of air excess ratio 1.3. In addition, we measured emission characteristics under the lean bum and charging condition. From this experiment, we found that CO emission is out of the question in the range from stiochiometric to lean burn and charging condition, but charging pressure has influence on HC emission.
