The purpose of this study is to investigate industrial safety and health experts' opinions on the examination system of WMSDs(work related musculoskeletal disorders) risk factors. For doing this, a questionnaire study and two FGIs(focused group interview) were conducted. A questionnaire with open questions about the examination system was developed, and sent to 42 experts consented bye-mail. Of the experts, 24 experts responded, whose data were used in the analysis. The FGIs were performed for the persons in charge of industrial safety and health in industries and ergonomists. The questionnaire study revealed that most experts(91.3%) agreed with legalization of employers' duty for preventing WMSDs, necessity of the 11 tasks designated by Ministry of Labor, the examination system and ergonomics program, and pertinency for the examination system classification of periodic and occasional one. However, more than half experts disagreed with timeliness and appropriateness of the legal system. This was validated by the low approval rates for appropriateness of the 11 tasks, methods of the examination, charge person in the examination and ergonomics program. FGIs showed that it was desirable for the examination system to be legalized, and that the system was generally properly performed. It was suggested that the system be partially revised with reflecting problems disclosed during its enforcement rather than whole revision. It is expected that when revising relevant legal system, the results of this study would be used as valuable data.

The Islamic jurisprudential legal system represents an essential component of the Islamic religion, that governs many aspects of Muslims' daily lives. This creates many questions that require interpretations by qualified specialists, or Muftis according to the main sources of legislation in Islam. The Islamic jurisprudence is usually classified into branches, according to which the questions can be categorized and classified. Such categorization has many applications in automated question-answering systems, and in manual systems in routing the questions to a specialized Mufti to answer specific topics. In this work we tackle the problem of automatic categorisation of Islamic jurisprudential legal questions using deep learning techniques. In this paper, we build a hierarchical deep learning model that first extracts the question text features at two levels: word and sentence representation, followed by a text classifier that acts upon the question representation. To evaluate our model, we build and release the largest publicly available dataset of Islamic questions and answers, along with their topics, for 52 topic categories. We evaluate different state-of-the art deep learning models, both for word and sentence embeddings, comparing recurrent and transformer-based techniques, and performing extensive ablation studies to show the effect of each model choice. Our hierarchical model is based on pre-trained models, taking advantage of the recent advancement of transfer learning techniques, focused on Arabic language.

우리나라 유역 상류부의 물 공급 소외 지역에서 취수원 용량이 극히 제한적인 계곡부 지역 등을 대상으로 샌드댐을 설치·운영함으로써 대체수자원 확보시설로 활용하고자 하는 시도가 이루어지고 있다. 샌드댐이 가장 활발하게 설치·활용되고 있는 것으로 알려져 있는 아프리카 지역 일부 국가들의 경우 샌드댐에 관한 별도의 법제도를 수립·적용하고 있는 사례를 찾아보기 어렵다. 샌드댐은 지하수댐의 일종으로서, 그 개념, 구조적·기술적 형태와 특성, 목적과 용도, 기능 등에 비추어 현행 「지하수법」 상 명시되어 있는 지하수자원확보시설로서의 법적 성격과 지위를 갖는다고 할 것이다. 지하수자원확보시설에 관한 규정의 해석과 적용 역시 이를 뒷받침한다. 따라서 샌드댐 사업은 「지하수법」을 근거로, 지하수자원확보시설의 설치·관리 사업의 하나로 추진·시행되는 것이 법논리적으로나 현실적으로 타당하고 합리적이다. 다만, 현행 명문 규정상 지하수자원확보시설에 샌드댐이 당연히 포함되는 것으로 볼 수 있는지에 대해서는 다소 명확하지 않은 점이 있어 그에 관한 종합적 고찰과 더불어 관련 법제도의 개선이 요구된다고 할 것이다.

Software Defined Network (SDN) realizes management and control over the underlying forwarding device, along with acquisition and analysis of network topology and flow characters through south bridge protocol. Data path Identification (DPID) is the unique identity for managing the underlying device, so forged DPID can be used to attack the link of underlying forwarding devices, as well as carry out DoS over the upper-level controller. This paper proposes a dynamic defense method based on Client-Puzzle model, in which the controller achieves dynamic management over requests from forwarding devices through generating questions with multi-level difficulty. This method can rapidly reduce network load, and at the same time separate attack flow from legal flow, enabling the controller to provide continuous service for legal visit. We conduct experiments on open-source SDN controllers like Fluid and Ryu, the result of which verifies feasibility of this defense method. The experimental result also shows that when cost of controller and forwarding device increases by about 2%-5%, the cost of attacker's CPU increases by near 90%, which greatly raises the attack difficulty for attackers.

This study identifies influential factors for invigorating the public management office (PMO) system for system integration (SI) projects in public sectors and analyzes the priority of each factor from the point of different stakeholders, i.e., owners, SI company, and PMO. Based on the literature review, four first-level influential factors are identified: legal system maintenance, owner's capability, SI company's capability, and PMO's capability. Among them, the PMO's capability is determined as the most critical factor by all the stakeholders. Among the second-level influential factors, the capabilities of professional engineers and project managers are considered as important among the PMO's capability, whereas the reasonable consulting fee is considered as the most critical factor among the legal system maintenance. With respect to each stakeholder, project management capability is considered as the most important factor for owners, while the reasonable consulting fee is considered as the most important factor for PMO.

The proper operation and safety management of water and wastewater treatment systems are essential for providing stable water service to the public. However, various natural disasters including floods, large storms, volcano eruptions and earthquakes threaten public water services by causing serious damage to water and wastewater treatment plants and pipeline systems. Korea is known as a country that is relatively safe from earthquakes, but the recent increase in the frequency of earthquakes has increased the need for a proper earthquake management system. Interest in research and the establishment of legal regulations has increased, especially since the large earthquake in Gyeongju in 2016. Currently, earthquakes in Korea are managed by legal regulations and guidelines integrated with other disasters such as floods and large storms. The legal system has long been controlled and relatively well managed, but technical research has made limited progress since it was considered in the past that Korea is safe from earthquake damage. Various technologies, including seismic design and earthquake forecasting, are required to minimize possible damages from earthquakes, so proper research is essential. This paper reviews the current state of technology development and legal management systems to prevent damages and restore water and wastewater treatment systems after earthquakes in Korea and other countries. High technologies such as unmanned aerial vehicles, wireless networks and real-time monitoring systems are already being applied to water and wastewater treatment processes, and to further establish the optimal system for earthquake response in water and wastewater treatment facilities, continuous research in connection with the Fourth Industrial Revolution, including information and communications technologies, is essential.

Objectives: Given the real problems at industrial sites related to the Serious Accident Punishment Act (SAPA), it has become controversial as a particularly important issue in terms of occupational safety and health. I intend to examine in detail what are the problems and how to approach them. Methods: The contents of SAPA were reviewed focusing on whether its provisions conform to the principles of occupational safety and health, whether they fit the related legal theory, and whether they are effective for accident prevention. The purpose of this study is to examine whether there is a problem with SAPA from the perspective of the effectiveness of accident prevention by combining occupational safety & health management theory, and legal theory. Results: In order to ensure the effectiveness of SAPA, it should be revised to increase the predictability and implementation of safety and health measure standards. Otherwise, it is expected that there will be not only economic and social costs in the short term, but also side effects that disrupt the safety law system, resulting in a considerable number of post-mortem conditions in the mid- to long term. Conclusions: It is easy to see in comparative law that raising the legal punishment alone does not have the effect of preventing industrial accidents. SAPA should be revised as soon as possible in the direction of faithfully and elaborately reorganizing the standards for safety and health measures.

Objectives: South Korea's occupational safety and health legislation appears on the surface to have stronger regulations than any other country, but it is criticized for having many problems when viewed from the perspective of the effectiveness and universality of these regulations. Therefore, it is necessary to consider the validity of the regulatory content and the methods for contract work in South Korea. Methods: The main issues in contract work are compared and analyzed in terms of the occupational safety and health laws systems in South Korea and other developed countries. Based on this, problems related to contract regulation are derived from the perspective of legal policy studies. In addition, effective improvement measures for the derived problems will be proposed. Results: Other developed countries impose obligations suitable for the status and role of persons who entrust work in consideration of the fact that they do not directly manage risks and in terms of the effectiveness of industrial accident prevention. These countries generally impose obligations such as management of facilities and machinery, cooperation and coordination with subcontractors, cooperation and coordination obligations between subcontractors, and guidance obligations on a person who entrusts a work. Conclusions: It is difficult to achieve effectiveness in preventing accidents with based on unreasonable regulations that do not conform to safety principles or legal theory. Regulations on contract work need to be converted to rational cogent regulations based on science and rationality, not ideology and emotion. To this end, the legal system for contract work must have international universality.
