In respect of the existing relation between Sea-going Vessels and Vessels at anchor, Korean Maritime Safety Tribunal has applied 'Ordinary Practice of Seamen' that is regulated by the article No. 2 of COLREG. That is, general navigation rule is not applied between the two vessels, and the action to avoid collision of vessels by utilizing experience knowledge of the seamen. However, the content of the Ordinary Practice of Seamen included in the revised plan in the process of 2011 "Maritime affairs Safety Act" revision was deleted in the screening of the Office of Legislation due to the reason that it could not specified when the content of deed is not concertized. Furthermore, prior application regulation of international treaty included in the existing "Sea Traffic Safety Act"(Article 5) was deleted in the screening of the National Assembly. So, doubt about whether the Ordinary Practice of Seamen could be continuously applied according to the regulation of the international treaty, nevertheless not specified in domestic law, has been continuously raised. In this situation, recently Central Maritime Safety Tribunal changed precedent by applying of Article 96(3) of Maritime Safety Act without applying Ordinary Practice of Seamen in the Case No. 2015-001. Accordingly, this study intended to review propriety of precedent change and legal issue with the decision of Central Maritime Safety Tribunal excluding Ordinary Practice of Seamen for a collision between Sea-going Vessels and Vessels at anchor.

Background and Objectives The effectiveness of many physiotherapy modalities in reducing subcutaneous fat has been investigated in numerous previous studies. However, to the best of our knowledge, there have been no attempts to determine the effectiveness of physiotherapy modalities in body contouring. The present report determined the effect of 448-kHz capacitive resistive monopolar radiofrequency (CRMRF) in a porcine model. Materials and Methods This study investigated the effect of selective destruction of the subcutaneous fat layer in abdominal fat tissue using CRMRF. The effects of two types of CRMRF (capacitive electric transfer (CET) and resistive electric transfer (RET)) treatment were evaluated using regular digital photography in addition to thermal imaging evaluation, ultrasound measurement, hematological evaluation, and histologic analyses (H&E (hematoxylin and eosin), Oil red O, and immunohistochemistry staining). Results Preclinical evaluation was performed to obtain the data for comparison of the safety and efficacy of the subcutaneous fat reduction after applying CRMRF using CET and RET. After treatment, the thermal transmission was effective, and a 42-47℃ temperature change was observed in the fat layer while an approximately temperature of 42℃ was confirmed on the skin surface. Moreover, after the application of both types of CRMRF treatment, fibrotic septa were observed in the adipose tissue induced by heat at the treatment sites. TUNEL staining was also performed to confirm the process of apoptosis in the adipocytes. Conclusion These results suggest that both CET and RET for CRMRF treatment are safe and effective for subcutaneous fat reduction in a porcine model.

This study examines whether startup firms start with the resources they already have and expand the resources they can mobilize in the process of business management (Effectuation Model) using public data provided by the government. The results of the study show that the Effectuation Model can partially explain the behavior of early-stage startup firms. Therefore, in terms of policy implications based on these findings, government policies for entrepreneurship should not be based on the selection of companies based on sophisticated business models and hypothetical profit models, but rather on a system that actively supports entrepreneurship in areas that are challenging, even if they seem somewhat reckless at the moment, or that best match the entrepreneur's knowledge. Next, in order to actively spread entrepreneurship, it is necessary to spread business history or entrepreneurial experience. To this end, it is necessary to drastically change the current financial system for startups, where the founder bears all the financial risk, and to more actively consider ways to reduce the risk of startups by allowing society and the financial system to share some of the risk of startups.
