This paper presents the development of the automatic safety inspection technique for the ammunition fuzes using radiography images. The technique inspects 49-ammunition fuze by detecting the X-ray or neutron radiographic images to check whether the fuze is unintendedly armed or/and some major assembled parts are at right place. To execute the program, we loads the image(s) for under test. After reading images, the program conducts a series of pre-image processing, and then starts inspecting input images by using the detection algorithms which are designed distinctively for each fuze. After completing the detection process, the program displays the final result of the fuze status: "safety or danger." Through this program, we can cut off the fuzes which have any doubt about safety, and can only provide absolutely safe fuzes, compared with the current naked eye inspection method.

Purpose: This study was conducted to investigate the cognition level and the performance level of universal precautions on blood-borne infections and to analyze related-factors on the performance level for universal precautions among the nurses. Method: A total of 166 nurses participated in the survey. We performed multiple linear regression to assess the related-factors on the performance level for universal precautions. Result: The mean scores of cognition and performance level for universal precautions were 65.61(±8.74) and 53.98(±8.42) respectively. The mean score of the cognition level was significantly lower than the performance level in all items. The cognition level was associated with the working field. The performance level was highest for nurses working over 36 years, nurses in university hospitals, and nurses in the operating room. The cognitive level for universal precautions, education level, exposure to blood-borne infection, familys income, and marital status significantly predicted the performance level for universal precautions in the multiple linear regression model (Adjusted R2=0.42). Conclusion: The cognition level for universal precautions is the strongest predictor on the performance level for universal precautions. An integrated approach should incorporate training experiences to improve cognition and perception of risk on universal precautions for preventing blood-borne infections.

본 연구는 직업분류 및 고용분류별 스트레스, 스트레스 상담, 우울증상, 우울증상 상담 정도를 파악하기 위해 지역사회건강조사 자료를 이차 분석하였다. 직업분류별 및 고용분류별 확실한 비교를 위해 기준 직업 군으로 ‘무직(직업분류 기준항목)’과 ‘무급가족종사자(고용분류 기준항목)’를 포함하여 한국표준직업분류(6차 개정)에 의한 총 13개의 직업군을 이용하였다. 직업분류 및 고용분류별 스트레스, 스트레스 상담, 우울증상, 우울증상 상담 여부의 교차비에서는 ‘무직’과 ‘무급가족종사자’의 스트레스 정도가 대체적으로 더 낮게 나타난 반면, 스트레스 상담, 우울증상, 우울증상 상담에서는 ‘무직’과 ‘무급가족종사자’가 오히려 더 높은 교차비를 보였다. ‘관리직’을 포함한 7개의 직업군은 ‘무직’보다 스트레스를 많이 받지만(OR > 1), 의료기관 이용률은 낮게 나타났다(OR < 1). ‘고용주 및 자영업자’와 ‘임금근로자’가 ‘무급가족종사자’에 비해 높은 교차비를, 스트레스 상담 및 우울상담에서는 낮은 교차비를 보였다. 본 연구는 정신건강문제 선별 및 관리를 위해 특정 인구집단에 대한 접근을 통해 직장 내 정신보건서비스 제공에 대한 필요성을 시사하고 있다. The purpose of this study is to examine the level of stress and depressive symptom and to assess the utilization of professional consultation. Data extracted from Community Health Survey (CHS), conducted by Korea Centers for Disease Control and Prevention. The subjects were 174,975 (19-65 years). In result, ‘Managers’, ‘Professionals and related workers’, ‘Clerks’, ‘Service workers’, and ‘Sales workers’, ‘Equipment, machine operating assembling workers’, and ‘Armed forces’ were more in risk of stress. However, theses groups were less in probability of utilization for stress consultation. Based on these findings, mental health screening program for detecting risk group among occupation classification and employment status will be essential. It may be necessary to have sustainable strategies for utilizing mental health service to reduce the level of stress and depressive symptom of workers.

신관 안전장전장치는 비행체의 수송, 저장, 취급 중의 안전을 절대적으로 보장하도록 설계되어야 한다. 본 논문에서는 비행체에 적용되는 신관 안전장전장치의 안전성을 증대시키기 위한 솔레노이드 조립체와 솔레노이드 조립체를 구동하기 위한 솔레노이드 구동회로를 포함한 신관 안전장전장치 설계에 대해 기술한다. 솔레노이드 조립체는 신관 안전장전장치에 적용한 추가적인 안전장치로서, 코일 조립체, 복원스프링, 코어 등으로 구성된다. 솔레노이드 조립체의 코어는 평상시에는 1차 안전장치를 구속하고 있어 1차 안전장치가 작동하는 것을 저지해줌으로써 비행체의 취급이나 수송 시 안전을 확보해주게 되며, 발사를 위한 비행체 배터리 전원이 인가 및 활성화되어 신관 안전장전장치에 공급되면, 솔레노이드 구동회로가 코어를 작동시켜 신관 안전장전장치의 1차 및 2차 안전장치를 해제시키는 역할을 한다. 또한, 솔레노이드 구동회로는 비행체 발사 이후, 신관 안전장전장치의 기계적 장전이 완료되어 장전스위치가 turn-on되면 솔레노이드 조립체에 인가되는 전원을 자동 차단시켜 비행 중의 전원 소모량을 줄일 수 있도록 하였다. The safety and arming device(SAD), one of the components of the fuzes, shall provide safety that is consistent with handling, storage, transportation, use, and disposal. In this paper, we describes the design of the SAD which includes the solenoid assembly and the solenoid driving circuit to improve the safety of the fuzes. The solenoid assembly consists of a coil assembly, a restoring spring, and a core. The solenoid assembly is added in the SAD as an additional safety device. In case of the normal circumstances, the core of the solenoid assembly restrains the 1st and 2nd safety devices of the SAD for those devices not to operate at all, so that the SAD can secure safety for storage, transportation, and use. In contrast, when the battery power is provided to the solenoid driving circuit just before the flight, the core confirms the power level and starts removing the restraint from the 1st and 2nd safety devices of the SAD, and then the SAD is able to change its mode from safety mode to armed mode. After firing, once the SAD’s operations complete, the turned-on arming switch stops providing the power to the solenoid assembly automatically. It can reduce the power consumption at solenoid assembly. Therefore, the proposed solenoid driving circuit for the solenoid assembly not only unlocks the restrained solenoid assembly from the safety devices, but also saves the power consumption during the flight.

Purpose : The aging population is the quickly increasing in Korea. Since 2008, the National Long term Care Insurance, a number of long term care facilities have established during short time in Korea. Especially, the environmental assessment tool is important for managing healing environment in a long term care facility for the elderly. Alzheimer`s Garden Audit Tool (AGAT) is used to assess whether a garden incorporates those elements and qualities as healing outdoor space. In this paper, we discuss the benefits, limitations, and future directions of the assessment tool for long-term care facilities. Methods : The AGAT audit was done through content analysis by 5 experts from diverse discipline as post occupancy evaluation of a long term care facility located in suburban area. The expert group was asked to describe their comments for modification and improvement in application of AGAT. Results : The results of this study show that it is necessary to refine the instrument`s items to better meet the needs of the criteria and items for Korean culture-friendly tool. Especially, greenhouse elements (various plants, birds etc.), multisensory experiences, users-oriented space, programmed activities in garden, and hazards on pathway has somewhat limitation as measurement to assess outdoor of long-term care facilities in Korea. Implications : Consequently, AGAT could be applicable to evaluate the outdoor space of long term care facility in Korea with culturally sensitive revision.
