For the phase measurement of radar signal in the coherent-on-receiver system, the COHO(Coherent Oscillator) generates the signal which locks to the phase of the transmit pulse. In this paper, COHO unit is developed to generate 60 MHz phase-locked signal. ILO(Injection Locking Oscilator) locks to the sample of the transmit pulse. Gate circuit, ILO, buffer amplifier, and pulse generator are designed and implemented.

Handling precise timing in high-speed transceivers has always been a primary design target to achieve better performance. Many different approaches have been tried, and one of those is utilizing the beneficial nature of injection locking. Though the phenomenon was not intended for building integrated circuits at first, its coupling effect between neighboring oscillators has been utilized deliberately. Consequently, the dynamics of the injection-locked oscillator (ILO) have been explored, starting from R. Adler. As many aspects of the ILO were revealed, further studies followed to utilize the technique in practice, suggesting alternatives to the conventional frequency syntheses, which tend to be complicated and expensive. In this review, the historical analysis techniques from R. Adler are studied for better comprehension with proper notation of the variables, resulting in numerical results. In addition, how the timing jitter or phase noise in the ILO is attenuated from noise sources is presented in contrast to the clock generators based on the phase-locked loop (PLL). Although the ILO is very promising with higher cost effectiveness and better noise immunity than other schemes, unless correctly controlled or tuned, the promises above might not be realized. In order to present the favorable conditions, several strategies have been explored in diverse applications like frequency multiplication, data recovery, frequency division, clock distribution, etc. This paper reviews those research results for clock multiplication and data recovery in detail with their advantages and disadvantages they are referring to. Through this review, the readers will hopefully grasp the overall insight of the ILO, as well as its practical issues, in order to incorporate it on silicon successfully.

The Maritime Labour Convention, 2006, (MLC) aimed to ensure decent working conditions for seafarers and entered into force on August 20, 2013. It was considered as the fourth pillar in the maritime sector. This paper evaluates how the MLC has been implemented in the field and what issues were addressed in the shipping industry. To achieve this, statistical analysis was conducted using inspection data of Port State Control (PSC) carried out by the Paris MOU and the Tokyo MOU during 2010-2012 and 2014-2016 for deficiencies under the MLC and International Labour Organization (ILO) No. 147 Convention. This study compared pre-2013 and post-2013 deficiency data according to ship's age, size (gross tonnage) and type. The results showed that, although the deficiencies reported by the Tokyo MOU during 2014-2016 were nearly double those from 2010-2012, the deficiency share against total deficiencies for the Tokyo MOU remained two thirds of those for the Paris MOU. This study suggests that the Tokyo MOU should strengthen its inspection efforts on MLC and ILO should provide clear references, such as guidelines and a unified interpretation for national discretions under the MLC for the purpose of harmonized PSC inspections. Additionally, it would be desirable to consolidate the deficiency coding system for the MLC by deleting the codes for the ILO No. 147 Convention, which was incorporated into the MLC. It would also be beneficial to add new deficiency codes for social security, including seafarers' leave and repatriation.

The purpose of this study is to provide some ideas for the improvement of the seafarers physical examination systems(PES) in Korea. This paper presents basic data about the items and detailed standards of the seafarers PES which are currently carried out worldwide. In this paper, a comparative analysis of the domestic and the foreign seafarers PES is conducted. In addition, rule of judgment in the railroad workers PES in Korea has been examined for reference. The paper proposes the amended and supplemented 16 items and detailed standards of the seafarers PES. Expert opinions of Occupational and Environmental Medicine specialist and the recommendations of ILO/WHO are also considered to draw an improvement scheme for the seafarers PES in Korea.

As of Jan. 2006, numbers of korean registered ocean-going vessels reached 546 which amounted to 13,716,733 G/T. Vessels, generally spooking, finish her life cycle and are dismantled or recycled. However, most of these activities have been done in undeveloped countries instead of in developed countries as the environmental restrictions in developed countries get more strict, accordingly international bodies adopted shipbreaking-related guidelines and prohibit transboundary of obsolete ships, taken as one of wastes. The authors made the Working Guidelines on Shipbreaking to cope with substandard working environment and reduce the environmental damage, and came up with a method to make a inventory of hazardous materials for effective control, finally framed a draft of Environmentally Sound Ship Recycling examining related international conventions such as Basel Convention, IMO Guideline, ILO Guideline and IMO new Convention(draft) on shipbreaking and recycling.

선박에서의 음용수는 승무원들에게 중요한 사항이다. ILO 국제협약에 따르면 "선박에 공급되는 식량과 청수는 선박 내에 근무하는 선원의 수, 식량과 관계 된 종교적 요구사항 및 사회적 관례 그리고 항해 기간 및 특징을 고려하여 양, 영양가, 품질 및 다양성의 점에서 적절하여야 한다."라고 되어 있어 이 내용은 너무 포괄적이고 양질의 청수에 대한 구체적인 내용이 미흡하다. 따라서 이 연구에서는 음용수에 대한 최소한의 기준 마련을 제시할 목적으로 음용수와 관련한 국제협약, 국내외의 법률 등을 살펴보고 음용수의 공급, 관리 등에 대한 개선방안을 제시하고자 한다.
