Objectives: The purpose of the Act is to comprehensively consider the legislative notice of the Enforcement Decree of the Serious Accidents Punishment Act for each important issue in terms of system, content, and execution. Methods: We examine the legislative notice of the Enforcement Decree of the Serious Accidents Punishment Act in-depth from the perspective of the effectiveness of disaster prevention, consistency of the legal system, and harmony with legal principles. Results: The proposed Enforcement Decree of the Act on the Punishment of Serious Accidents hardly resolves the uncertainties of the law, and there are many aspects that are unclear in the enforcement ordinance itself and that do not comply with constitutional principles. As a result, it is judged that it is difficult to for it to serve as an accident prevention standard due to its low predictability and that it will be difficult to achieve effectiveness in accident prevention. Conclusions: Ultimately, the law itself should be extensively reorganized in order to ensure universal and sufficient effectiveness, including the abolition of the Serious Accidents Punishment Act. In the short term, even the Enforcement Decree of the Act should be reorganized and supplemented in accordance with the law and safety principles.

This study aimed to prove the effects of acupuncture treatment on acupoint Joksamni(ST36) related to gastrointestinal movement. Electrogastrogram (EGG) data were obtained in 11 healthy subjects treated by real or sham needle in single-blinded condition for 40 min, including before, during acupuncture treatment, and after removing needle. According to frequency analysis of EGG, median frequency(MF) was increased by real needle in 4 subjects, MF for another 2 subjects were increased by real and sham needle and no trend shift in MF showed in other 5 subjects. Our result showed that acupuncture treatment on Joksamni has some effects on gastrointestinal movement. In this study we have applied both real acupuncture and sham acupuncture on the same subjects. So its blinding was regarded as good but was effective in about 36%~55%. Two subjects were assumed that they showed placebo effects on both real and sham acupuncture. Therefore it is necessary to perform further study on case-control and a larger number of subjects with functional dyspepsia, in order to confirm our findings.

Transport phenomena paly an inmportant role in bulk crystal growth processes. During crystal growth, the control of the growth front and the dopant concentration is crucial to crystal quality. The growth feasibility in thus determined by the heat transfer controlling the interface convexity and by the mass transfer controlling the constitutional supercooling. Through numerical modeling, a thorough understanding of the growth processes is possible, which in turn is a key to process improvenment. In this paper, we will summarize some work dine in my laboratory, both numerical and experimental, to illustrate the importance of understanding the transport phenomena during crystal growth processes.

본 논문에서는 우즈베케스탄 사람을 대상으로 한국의학에서 사용되고 있는 사상체질진단법을 적용하여 실험하였으며, 먼저 설문조사방법으로 체질을 진단하는 QSCC II(Questionnaire for Sasang Constitution Classification II)라는 진단기구와 음성분석으로 체질을 진단하는 PSSC(Phonetic System of Sasang Constitution)를 사용하여 체질을 진단한 후, 한국인과 마찬가지로 우즈베키스탄인들에게도 적용이 가능한지를 살펴보았다. 실험결과 우즈베키스탄인도 사상체질로 분류됨을 보았다.

In this study, the constitutional basis of public concept of land and concept of development gains are confirmed, and justification of the development charges system through the precedent of the Constitutional Court is investigated, and suggestions for improvement of fairness and reliability of development charges calculation are proposed. First, it is necessary to develop a system for estimating the development charges for securing transparency of the development charges system, preventing speculative development projects, and streamlining administrative efficiency. Second, it is necessary to prevent bad calculation by institutionalizing the responsibilities of experts to construct specification of the development cost calculation sheet submitted by taxpayers. Third, in order to precisely calculate the development cost, basic data should be specified in conditions for approval from the time of granting permission, or it should be minutely described in development charge treatment regulations.

The effects of geometric parameters (stack position, stack length, resonator tube length) and varying input power over acoustic energy output were investigated. The acoustic laser kit (Garret 2000) was used for the construction of TA lasers. A series of sound pressure level measurements in different orientations did not differ significantly confirming that the sound wave generated could be assumed as a spherical wave. An increase in acoustic pressure was recorded with respective increase in input power, stack and resonator tube lengths owing to their relative influence over heat transfer rate and critical temperature gradient across the stack.

The purpose of this study was to investigate the effect of pulsed magnetic field (PMF) and low frequency low level laser (LFLLL) stimuli on acupoint LI4 (Hegu) using photoplethysmography (PPG). Our PMF system was designed to generate maximum intensity of 0.20 T at a transition time of 0.16 ms, with pulse intervals of 1 Hz. The diode laser with wavelength of 650 nm and power of 5 mW was also employed. It was observed the change of the pulsating blood volume through measuring PPG signals from both hands. These results imply that stimulating acupoint LI4 with PMF and LFLLL improves the circulation of peripheral vascular system. In particular, PMF stimulation brings a big improvement of the blood flow even with short term stimulation of 3-4 minutes compared to LFLLL stimulus.

This paper describes an intelligent piezoelectric traffic sensor which can be detected the over-weighted vehicles In motion. Based on finite element analysis for the sensor, the sensitivity was analyzed and the design was optimized. Studied parameters are the material properties of constitutional parts, the geometry of the sensor, the weight of the vehicle, and the speed of the vehicle. To verify the simulated results, we manufactured the sensor having the optimized geometry and the sensitivity was measured in the range from 0.5 to 3 ton of tensile and compressive stress. The measured results shows that the sensitivity and linearity of the sensor are closely agree with the designed values.

We investigated the effects of pulsed magnetic fields (PMF) stimulus on electroencephalogram (EEG) alpha activity and heart rate variability (HRV) from electrocardiogram (ECG) measurements with various stimulus durations at acupoint PC9. The alpha activity in the EEG and the ratio of low frequency power and high frequency power (LHR) in the HRV, a reflection of sympathovagal activity, were increased and decreased, respectively, after PMF stimulus of 3 min. Our spectral analysis quantitatively proved that the changes in the EEG alpha activity were consistent with an autonomic function in the ECG. These findings suggest that appropriate PMF stimulus results in the same effect as that of acupuncture applied to the acupoint PC9, which is closely related to the parasympathetic activity of the autonomic nervous system.
