안타깝게도 질병은 소리 소문 없어 찾아온다. 당뇨병도 그렇지만 당뇨합병증은 더욱 생각지도 못하게 나타난다. 그래서 필요한 것이 정기검사이다. 당뇨병은 완치 되지 않으며, 혈관병이라 조금만 관리가 소홀해도 혈당은 조용히 혈관을 타고 각종 장기를 위협해 합병증을 일으키기 때문에 철저한 당뇨관리와 함께 정기적인 검사가 필수이다. 당뇨인이 받아야 할 합병증 검사에 대해 알아보자.

본연구는 콘크리트 타설과정에서 반복되는 펌프카 사고를 예방하기 위해서 설계 및 제작의 품질관리와 현(現))정기검사 기준을 개선해야 한다는 점을 제안하며, Booms 파단 사고 예방대책 제시가 목적이고, 최근 1~2년 사이에 발생한 펌프카 기계적 결함 사고의 현황조사와 사고 특징을 분석하고, 펌프카 장비의 검사기준 및 조정원의 자격과 기능교육 기준 마련의 필요성 확인한다. 붐대의 안전성 확인하기 위해서는 선행연구의 구조적 안전성 평가와 최대응력 부위에 대한 선행연구의 유한요소 해석모델 자료를 재분석하고, 2단 붐이 타설중 가장 많은 힘을 받는지와 파괴 가능성을 확인한다. Booms의 유한요소 모델 해석 결과 펌프카는 타설 과정에서 진동으로 피로 하중을 받을 수 있다는 동적해석과 정적해석 재검토 결과 가장 취약한 부위는 2단 붐이었으며, 2st 붐은 제작단계에서 부재 두께를 증가시키고, 상단부에 철판 보강을 권장한다. 펌프카 사고를 방지하기 위해서는 제조사는 생산단계에서 2st Boom 상단에 보강판 부착이 필요하고, 정기검사 비용 현실화와 비파괴 검사를 의무 검사로 반영이 필요하다고 제언한다.

For missile systems, sustaining high reliability and ensuring economical maintenance are very important. In the Republic of Korea, for most missiles, periodic inspection is mandatory for missiles in the field. Every fixed number of years, they are returned to the ordnance depot to be tested and repaired if faults are found. Almost all missiles have a built-in test (BIT) capability. With the BIT, faulty missiles can be isolated anytime during operations or storage in the launchers. So the reliability and the maintenance costs of the missiles greatly depend on the length of the inspection cycle and the BIT/inspection quality. In this paper, we suggest a model for predicting the storage reliability of missiles subjected to non-periodic tests and periodic inspections, excluding overlapping failures. Some numerical examples are given. This model will be useful for determining the length of the periodic inspection cycle.

2014년 12월, 한국수력원자력의 사이버테러, 이란의 원자력 농축시설을 대상으로 한 사이버공격 등 국내외에서 원자력시설을 대상으로 한 사이버공격이 발생하고 있다. 이에 따라, 사이버보안 중요성이 증가하면서 방사선 재해방지와 공공의 안전을 위한 효과적인 규제체계의 필요성이 증가하였다. 한국원자력통제기술원은 개정된 방사능방재법에 따라 2014년부터 사이버보안 정기검사를 수행하고 있으며, 정기검사에 활용할 취약점 점검툴을 통해 정기검사의 효과성 및 수행능력을 향상시키고자 한다.

The regular inspection of vehicles that are in service in domestic country, i.e., vehicle safety and emission gas inspection have been forced by the korea transportation safety authority and a private servicing enterprise according to the vehicle administration law (1995). In the safety inspection process, which is developed by a compatible inspection system and method, every effort is made to increase the reliability of vehicle safety and the service quality, and to protecting national health. In this study, the reliability of the braking force inspection method in the current regular vehicle inspection was studied statistically by comparing the dynamic braking force inspection method with the static braking force inspection method. Further, the problems and characteristics of the current braking force inspection methods were analyzed. Form the results for the dynamic braking force inspection equipment (H), a mean correction factor (y=18.61+2.18x) was obtained for the axle braking force ratio according to vehicle entering velocity.

The particulate matter that was emitted always come up by atmospheric environmental problem. Running on the road vehicles must have regular inspection at regular period and make sure the emissions of exhaust gases exceed the legal standards. Emission test for the atmospheric environment, but it is not free from the particulate matter. Currently, emission test of vehicle inspection is divided into regular inspection and close inspection. Regular inspection and close inspection differ not only the method of emission test, but also the facility standards that must have for this inspection. According to the "Regulations on the Implementation of Comprehensive vehicle Inspection, etc.", close inspection must have trapping device that is trap particulate matter by emission test to vehicle. However, regular inspection is different. Regular inspection do not specify any criteria for trapping facilities. Therefore, this study is confirm how to prevent the emission of particulate matter to the atmosphere during the year when mandatory trapping facilities are required to trapped particulate matter in the regular inspection.

This study has analyzed soft contact lens care-after-sale and periodic examinations at optical shops and eye clinics. And I wish to make that use of educational data for the soft contact lens lesson of the department of ocular optics. This questionnaire studied the status of care for soft contact lens and periodic examination, of students who wears soft contact lens. The results are as follows: First, 7.5% of students questioned wore soft contact lens. More women than men wore soft contact lens. The soft contact lens wearers purchased lens mainly at optical shops. 78.5% of them wore daily wear lens. Because of cosmetic advantages of soft contact lens. 47.9% of them wore soft contact lens. 72.5% of them wore soft contact lens less than 12 hours per a day. 32.0% of them has worn soft contact lens more than 6 months less than 1 year. 51.1% of them experienced irritation. 39.7% of them have exchanged soft contact lens between 6 and 9 months. Secondly, when purchasing lenses. 60% of soft contact lens wearers were given instructions of general care, such as duration of wearing lens, how to remove protein, how to store, and how to sterilize at both of eye clinics and optical shops. But the proportion of instructions, such as side effects and periodic examination which were given to soft contact lens wearers, is lower both at eye clinics and optical shops. Especially at optical shops, the proportion of instruction for periodic examination, is lower than at eye clinics(p<0.05). Thirdly, The proportion of operations of periodic examinations after use of soft contact lens both at eye clinics and optical shops, is low. The soft contact lens wearers have had more periodic examinations at eye clinics than at optical shops. But the rate of non-periodic examination at optical shop is 87.9%. And for periodic examinations, general care was done at optical shops. On the other hand, eye examinations, general care, and treatments were done more at eye clinics. Fourthly, 60.3% of the soft contact lens wearers understood the necessity of the periodic examinations, but actually, only 6.4% of them were given the schedule for the periodic examinations, and 2.5% of them were given at an optical shop(p<0.01).

The periodic technical vehicle inspection is to prevent the accident through the finding and fixing the defects of the vehicle. The periodic technical vehicle inspection in Korea was studied for assessing the adequacy of the inspection frequency. The inspection frequencies of many countries including EU, USA and Japan were compared. The average mileages by the vehicle usage and type were represented. The warranty period and recommended replacement period of parts of the domestic auto makers was studied. Currently, the inspection frequency for the periodic technical vehicle inspection in Korea is appropriate. The pass-fail rate and the cost-benefit analysis for the periodic technical inspection in Korea will be needed in the decision making process for the inspection frequency.
