The purpose of this study is to develop an efficient algorithm for the management of the shift schedule in nuclear power plants in consideration with the ergonomic criteria and the regulatory codes. The ergonomic criteria considered are the work hours, overtime-work frequency and working time, start and finishing time of works, allocation of rest times and duty-offs, rotating of shifts, etc. to comply with the regulations such as the Labor Standard Act, the ILO Convention No. 171, 178, "the detailed content of a periodic safety review," enforcement regulations 19-2 of the Atomic Energy Act. The developed algorithm for the shift schedule program adopts a heuristic method to minimize the difference the workload for shift workers in nuclear power plants.

When it is considered that many vehicle rides on the road and ride quality is an important method to evaluate vehicle performance with handling, running-over-bump manoeuvre may be suitable for testing ride quality. In this paper, a computed model has roughly steering system and lumped mass, connected by joint each rigid body, and suspension that has beam elements and has shock absorber as force element to represent nonlinear characteristics. A computer simulations for passing over a bump were made with two velocities. One side of vehicle passed over bump in due consideration of driver's habit that driver is subject to avoid a bad ride quality. On simulation, vertical acceleration, pitch angle and roll angle were measured at the mass center of chassis each case.

Until recently, dentistry did not show notable social conflicts with other medical professionals. This means that conflicts did not surface as medical doctors took the dominant position even though areas of intervention have been overlapped. The recent conflict between medical professionals, which began with clashes in the area of oral and maxillofacial surgery, have been embodied in the Supreme Court ruling on the use of Botox by dentists and the court ruling on the use of oral devices in oriental medicine. We look discuss at each case in detail to seek a solution to the problem of interprofessional conflict. We present professional duty of self-development and interprofessional education as a way to resolve disputes between medical professionals, which would be a major problem in the future of dentistry and medicine.

Government imposed a duty to perform feasibility investigation on huge development projects which cost are higher than 50 million dollars on May 1999. This is to prevent waste of money occur from lack of review on huge public projects and raise the efficiency of government budget. Although maintenance and managing analysis method for public infrastructures are developed and proposed by other institutions as Korea Infrastructure Safety & Technology Corporation but it is not well applied on the aspect of the railway fixed time and costumer costs. Therefore a good point of quantitative and qualitative reference which fits railway character is need and following guidelines from the phase of feasibility study are need to prevent governments budget waste.

2021년 3월 19일 한국생명윤리학회, 한국의료법학회, 한국의료윤리학회, 대한기관 윤리심의기구협의회는 감염병예방법 일부개정안과 병원체자원법일부개정안을 비판하는 공동성명서를 발표하였다. 이들은 공중보건상 긴급조치가 필요한 상황에서도 기관생명윤리위원회 심의는 필수적이며 생략할 수 없다고 선언하였다. 하지만 우리나라 생명윤리법은 국가나 지방자치단체가 공공복리를 위하여 수행하는 연구는 인간대상연구에서 제외하고 있다. 또한 우리나라 법제는 연구와 감시를 구분하는 이분법에 기초하고 있지 않기 때문에 미국 커먼룰의 논의를 그대로 우리나라에 적용할 수 없다. 국가의 감염병 관리 의무와 기관생명윤리위원회의 조화로운 운영을 위해서는 다음 사안들을 고려하여 제도적 대안을 마련해야 한다. 첫째, 관련 학계는 가장 먼저 우리나라 현행 법률의 문제점에 관심을 기울여야 한다. 둘째, 국가는 감염병 관리 의무를 이행하기 위하여 당사자의 동의 없이 많은 업무를 수행하고 있다는 점을 이해하여야 한다. 셋째, 제도적 대안을 제시할 때 우리나라에서의 집행가능성을 고려해야 한다. 제도적 대안에 대하여 의료법학회 등 관련 학계의 심도 있는 논의가 필요하다.

For the first Maritime Accident Inquiry System in Korea, Central Marine Accidents Inquiry Committee were founded in Seoul and District Marine Accidents Inquiry Committee in Busan city In 1963 to determine the circumstances of the accidents and causes. At the present day, it was settled as Maritime Safety Tribunal tough several revision of the Law and regulations regarding the Maritime Accident Inquiry System. In Korea, there occurred about m cases of marine accident, and as a result, about 200 people were lost human lives in average per year. In accordance with the change of circumstances such as traffic increasing and being bigger in size, being faster in speed, etc., the causes of the marine accidents become complicated year by year. Accordingly, in this moment, it is meaningful that the introduction of the Research Official who assists the Judges probing the cases fair and square. In this Paper, with the consideration of the several kinds of Research Official System, such as the Research Official of the Korean Supreme Court, the Supreme Public Prosecutors' Office and the Constitutional Court, Japanese Supreme Court, Law Clerk in USA, etc., the selection, numbers, duty of the Research Official were studied. The results of the study are as follows; 1. The Research Official to be appointed among the person having long enough career as a Judge, Investigator engaged in the Maritime Safety Tribunal due to he sho띨d have capability to confirm perfectly logical judgement and to collect enough material for the conclusion of the causes of the case. The one who understands the foreign language is preferred for the study of the foreign cases; 2. It will be logical to post 3 joint Research Officials in Korea Maritime Safety Tribunal in Seoul after due consideration the cases treated a year; 3. It will be logical for the Research Official to perform the collection of material and inspection of the scene for the trial and inquiry of the cases, to attend the cases filed suit to the Supreme Court, to make commentarial papers regarding the judged cases, to collect statistics of marine accidents and to devise a reform measure through in-depth analysis of the accidents frequently occurred, to study for the improvement of the Maritime Accident Inquiry System;

The piston engine is an essential component in automobiles. Since the piston is used in a high temperature and high pressure environment, the piston needs to be manufactured to achieve high strength and high durability. In addition, cost reduction is also an important consideration. In conventional forging, an additional heat treatment after hot forging is necessary to ensure proper mechanical properties for heavy-duty engine pistons. The newly developed manufacturing method lowers production costs by saving manufacturing time and reduces energy consumption. The current paper describes the hot forging of an engine piston made from 38MnSiVS5 micro-alloyed steel using controlled cooling. The finite element analysis was used to check for possible problems and suitable press capacity. Hot forging experiments were then conducted on a 2500tons crank press to evaluate feasibility of the proposed material and process. To check the mechanical properties after hot forging, the forged specimens were tensile tested, and the microstructures were examined in order to compare the results with the conventionally forged material. The skirt region of the as-forged 38MnSiVS5 piston showed better material properties compared to the conventional material. In addition, the total production time was reduced by about 80% as compared to conventional forging.

임의동행은 경찰행정작용 또는 임의수사의 한 방법이다. 피의자 등은 수사기관의 임의동행의 요구를 받았을 때에 임의로 동행을 승낙할 수도 있고, 거부할 수도 있다. 피동행자가 임의동행을 거부하였을 때에는 수사기관은 동행을 강요할 수 없고, 구속의 요건이 있을 때에 한하여 체포영장을 발부받아 체포하거나, 긴급구속의 요건에 해당될 때에는 영장 없이 긴급체포 형식으로 강제 동행한 후 구속영장을 청구할 수 있다. 이러한 처분은 형사소송법의 규정에 의하지 않는 한 피동행자의 신체를 구속하거나 그 의사에 반하여 답변을 강요할 수 없기 때문에 문제가 되는 것이다. 이러한 문제를 입법론, 판례 등을 참고하여 실제 우리나라의 임의동행에 의한 수사의 적법성에 부수하여 운영실태의 범위와 한계 등 책임성 문제를 고찰해 본다.

At the moment, in Korea, over 90% of energy resources depend on imports, and nearly 60% of electric energy is produced using fossil fuel. Therefore, the government adopted the Climatic Change Convention and has implemented the RPS system since 2012 to actively cope with the dependence on imported energy, and to grow and expand the new renewable energy industry. This study examined the performance results of mandatory supply of solar photovoltaic energy and non-solar photovoltaic energy assigned to providers and the present state after implementation of the RPS system. As a result, the achievement rate in 2012 was 64.7%. Especially, solar photovoltaic energy showed a high achievement rate of 95.7%, whereas non-solar photovoltaic energy showed a low achievement rate of 63.3% due to several problems and was highly dependent on the government. In 2013, the burden of each provider has increased due to more mandatory supply and addition of unfulfilled supply of 2012, and the separate mandatory supply of solar photovoltaic energy established for protection of the solar photovoltaic market is restricting investment. Therefore, there is a need to assign mandatory supply in consideration of the available amount of each new renewable energy.
