Personnel maintaining or repairing the railway tracks or signaling facilities around tracks may experience the sensory disorder when doing maintenance works at the trackside of railway for long time. In this case personnel maintaining at the trackside may collide with the train since they cannot recognize the approach of motor-car although it approaches to the vicinity of maintenance workplace because of the sensory block phenomenon occurred due to their long hours of continued monotonous maintenance work. In order to prevent such motor-car accidents that may occur because railway track workers are unable to recognize the approaching train, the safety alarm equipment is developed to make the approaching motor-car send radio signals and bidirectional detection mechanism between approaching train and trackside personnel. It shows the possibility of utilization in various forms of safety equipment for workers only to the safety helmet to be worn by the maintenance workers while using the configuration of transmitting/receiving sides. In the paper it is represented new alarm equipment, which is the bone-anchored speaker-based safety helmet to be worn by the maintenance workers.

The South Korean military has undergone four changes in operating methods since its inception with 31 nursing officers in August 1948. While it initially began as a special unit for nursing and other specialized services, it later expanded to include various fields including technology, administration, and special forces. However, analysis shows that there have been few significant changes in how it operates and remains largely centered around technology, administration, and special forces. With the development of advanced science and technology and a decrease in military resources, there is a need for the South Korean military to proactively expand its use of female personnel, as has been done by the US military, Canadian military, Israeli military with female conscription, and Norwegian military. In order to achieve this, there needs to be a cultural shift towards co-ed military units, improvements in facilities and equipment, adequate pay and benefits, and resolution of childcare issues through institutional reforms.

본 연구의 목적은 코스닥 기술특례 상장기업을 대상으로 관계인사 존재 여부가 시장에 신호 효과를 주어 IPO시 성과에 영향을 미치는 지를 살펴보고자 하였다. 기술특례상장제도는 기술우위 스타트업과 벤처기업들의 기술력과 시장성 등을 기반으로 기업공개를 통한 자금조달을 확보하여 미래 성장이 가능하도록 도입된 제도이다. 분석대상은 기술특례상장제도가 도입된 05년부터 21년까지 상장된 기술특례기업 135사(스팩합병, 외국기업 제외) 모두를 대상으로 하였다. 관계인사는 공무원, 유관기관 경력자, 자금조달관련 금융기관경력자, 변호사 등 전문직으로 정의하였다. IPO시 성과는 선행연구를 바탕으로 상장시 기업가치와 상장소요기간으로 분석하였다. 분석 결과, 단순히 관계인사 존재 여부가 기업가치 혹은 상장소요기간에 유의미한 영향을 주지는 않는 것으로 분석되었다. 이는 공무원, 유관기관 등 관계인사로 범위를 축소하여 검증한 결과도 마찬가지로 나타났다. 다만, 특정 조건하에서 관계인사 존재가 기술특례상장기업 상장에 미치는 유의미한 결과가 도출되었다. 관계인사 존재와 VC투자가 같이 있는 경우 기업가치에 유의미한 영향을 미치고, 기술특례상장기업 중 바이오 업종의 경우 공무원, 유관기관 등 관계인사가 존재하는 경우 상장소요기간에 유의미한 영향을 미치는 것으로 나타났다. 본 연구는 기술특례상장제도가 도입된 이후의 모든 기술특례상장기업을 대상으로 관계인사 존재 여부의 신호효과를 체계적으로 분석하였다는 점에서 의의가 있다. 또한 분석 결과 기술특례상장 준비 기업은 단순히 관계인사 영입보다는 VC투자와 병행되는 등 기술성과 시장성을 확보하기 위한 내실화된 노력이 더 중요함을 알 수 있는 결과를 도출하였다.

A medical personnel could be placed beside a patient together in CT room to do Ambu-bag for a seriously ill patients or emergency patient. At this time, the medical personnel can be exposed indirect radiation unnecessarily. In this case, it is necessary to recognize indirect radiation dose levels and methods to reduce them using actual clinical CT protocols such as Chest, Abdomen, and Brain CT. We researched surface radiation dose with or without radiation protectors such as apron and goggles according to different distances far from gantry using two different CT scanners (Fixed MDCT and mobile CT). As a result, for Chest, Abdomen, and Brain CT with Fixed MDCT, indirect radiation dose on thorax portion were 0.047, 0.089, 0.034 mSv without apron. Also, those with apron were 0.007, 0.012, 0.006 mSv. In case of mobile CT, it was 0.014 mSv without apron and 0.005 mSv with apron. By using protectors and increasing the distance, we could reduce it to 97%. Systematic management is necessary based on the measured data in order to minimize radiation damage due to indirect exposure dose.

Purpose - This study analyzes the intertemporal patterns in personnel decisions made between a supervisor and a subordinate to understand potential supervisor bias in the decisions. A correlation between the current and the most recent personnel decisions made for a subordinate by a current supervisor captures certain relationship-embedded and time-invariant factors in effect. The characteristics speak to the nature of a supervisor bias arising from a relationship, or favoritism. Design/methodology/approach - This study manually collects the executive profile data from annual reports of key Samsung Group affiliates and compile a longitudinal sample of 3,675 executive-years. It mainly explores the logistic regression analysis. Findings - The study finds that a supervisor' previous promotion award to a subordinate does not improve but decreases the likelihood of promotions in ensuing years, suggesting the containment of favoritism; and that the time since the last promotion award to a subordinate by the current supervisor increases the likelihood of both promotions and dismissals of the subordinate. Research implications or Originality - The findings are generally consistent with the theory suggesting that incentive schemes that align interests between an individual and an organization will contain the form of a supervisor bias.
