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.

2018년 헌법개정을 통한 토지공개념 강화를 위한 개헌논란에서 보았듯이 토지와 관련된 정책문제는 지속으로 발생되고 있다. 본 연구에서는 토지공개념의 헌법적근거와 개발이익의 개념을 확인하고 헌법재판소의 판례를 통한 개발부담금 제도의 정당성을 조사한 후 개발부담금 산정의 공정성과 신뢰성 확보를 위한 개선방안을 제시하였다. 첫째, 개발부담금 제도의 투명성확보와 투기적 개발사업의 방지, 부과권자의 행정효율화를 위하여 개발부담금 추정시스템의 개발이 필요한 점과 둘째, 납부의무자가 제출하는 개발비용 산출명세서를 전문가에게 작성토록 제도화하여 부실산정을 방지하고, 셋째, 개발비용 산출을 위한 기초자료를 인 허가 시점부터 부관에 구체적으로 명시하거나 개발부담금 부과업무징수처리규정에 적시하여 제도화할 것을 제시하였다. 그리고 공사계획변경에 의한 설계변경시에도 첨부하도록 하여 준공후 개발비용 산정시 개발사업기간내 제출된 자료를 활용하도록 하여 개발비용의 신뢰도를 높이도록 제안하였다.

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.
