Some of radioactive contamination is unavoidable in the facilities using the unsealed radioactive material. The primary purpose of radioactive contamination control in the workplace with contamination concern is the effects from the potential intake of radioactive material into the body. This paper provides procedures to estimate the level of internal exposure for the worker based on the conservative assumptions and simple calculations. They consist of two processes; to calculate air concentration of radioactive material and annual intake by inhalation with contaminated air and to compare each of them to Derived Air Concentration and Annual Limit on Intake mentioned in the related notification. The procedures are applicable to make a decision on practical requirements for monitoring air contamination and internal exposure of worker as follows; needs for measurement of air contamination and internal exposure and acquisition of information on the design of the ventilation system.

고수동굴이 1973년의 종합학술조사 이래 관광지로서 개발된 이후에 동굴 주변의 상업지역이 어떤 특성을 갖고 있는가를 살피는 것이 본 연구의 목적이었다. 이를 위해 1996년 6월 11일 고수동굴 주변의 상점 46개의 경영주를 대상으로 설문조사를 실시하였다. 그 결과는 다음과 같이 요약될 수 있다. 첫째, 전체 상점 중 절반 이상을 차지하는 25개 업소들이 80년대에 개업하였고 90년 이후에 19개 업소가 상점을 개설했다. 둘째, 상점 경영 동기로는 고수동굴을 찾는 관광객이 많아 수익성이 높을 것으로 예상되어 상점을 개점했다는 경우가 절반 정도(47.8%)에 해당하고, 내 고향 자랑과 지역발전의 일환으로 개점한 경우와 관광사업 발전을 위해 개점한 경우가 20% 내외였다. 셋째, 고수동굴 주변 상점의 경영주들은 일반사업을 하다가 전직한 경우가 가장 많았고, 관광사업, 오락장 등을 포함하면 상업 종사자들이 전체의 48% 정도에 해당하여 상업관련 종사자들의 전업이 가장 많았다. 넷째, 상점의 규모는 90년대에 개업한 상점일수록 규모가 커지고 있고, 이것은 경영주를 제외한 종업원의 운영과도 관계가 있어 상점 규모가 클수록 종업원이 더 필요한 것으로 나타났다. 다섯째, 경영주의 학력은 고졸 이상의 고학력자들이 상점을 운영하는 경우가 많아지고 있어, 고수동굴만의 특성을 나타낼 것으로 기대된다. 여섯째, 상점의 업종을 구분한 결과 기념품점과 식당이 각각 37.0%, 34.8%로 많은 비중을 차지하고 있지만, 고수동굴이 다른 관광명소와 색다른 특성이 없어 관광객들의 구매욕구를 완전히 충족시키지 못하고 있다. 마지막으로, 대부분의 상점들(80.4%)이 일자리와 주거를 구분하고 있는 것으로 조사되었으나, 아직까지 절반 가량(52.2%)의 상점들이 다른 사람 소유의 건물을 전 ·월세로 임대하여 사용하고 있음을 알 수 있었다. 이상에서 살펴본 바와 같이 고수동굴 주변의 상업적 특성은 90년대에 들어서면서 자기 고장에 있는 관광자원을 내 고향의 자랑거리로 생각하고 이를 지역발전의 밑거름으로 활용하고자 하는 인식이 늘어나고 있음을 알 수 있었다. 그러나, 관광지로서의 특성이라 할 수 있는 다른 관광동굴과의 차별성이 부족하다고 할 수 있다. 즉 다른 지역의 기념품점에서 구입할 수 없는 고수동굴만이 갖고 있는 특징적인 기념품을 판매함으로써 관광객의 구매욕구를 높인다거나 고수동굴의 일주관광 후 관광객을 좀 더 머무르게 할 수 있는 시설의 개발이 더 필요하다.

This study was conducted to investigate the reliability and validity of the Korean self-compassion scale using data from 312 correctional workers. To validate the self-compassion scale using the collected data, correlational analysis, exploratory and confirmatory factor analysis were applied. To explore relationships between the self-compassion scale and related instruments, five instruments were used (the Korean occupational stress scale, the center for epidemiological studies depression scale, the Maslach burnout inventory scale, perceived stress scale, and the satisfaction with life scale). The results showed that the collected data better fit the 6-factor model than the 3-factor and 2-factor models. There were statistically significant relationships between the self-compassion scale and five other scales. These results suggest that the self-compassion scale is a good instrument to examine risk factors that can remain during continuous stress situations and to explore protective factors that can maintain the therapeutic relationship. The implications of this study and future research directions were also discussed.

The explosive increase in demand for drones poses a major threat to the safety of existing aircraft operations and important national facilities operating in low-altitude airspace. In order to determine the type and degree of safety threats for low-altitude airspace drones, the types and types of threats from drones are evaluated through analysis of AHP(analysis hierarchy process) for aviation workers in each field. The composition of the threat factor hierarchy from drones was designed using a specific operation risk assessment (SORA) technique previously studied by the European Aviation Safety Agency (EASA), an advanced aviation country. Based on this, it will be possible to secure the low-altitude safety operation of existing aircraft by identifying and removing prior hazards between each aircraft operation and mission performance.

Proton therapy facility, which is recently installed at National Cancer Center in Korea, generally produces a large amount of radiation near cyclotron due to the secondary particles and radioisotopes caused by collision between proton and nearby materials during the acceleration. Although the level of radiation by radioisotope decreases in length of time, radiation exposure problem still exists since workers are easily exposed by a low level of radiation for a long time due to their job assignment for maintenance or repair of the proton facility. In this paper, the working environment near cyclotron, where the highest radiation exposure is expected, was studied by measuring the degree of radiation and its duration for an appropriate level of protective action guide. To do this, we measured the radiation change in the graphite based energy degrader, the efficiency of transmitted beam and relative activation degree of the transmission beam line. The results showed that while the level of radiation exposure around cyclotron and beam line during the operation is much higher than the other radiation therapy facilities, the radiation exposure rate per year is under the limit recommended by the law showing 1~3 mSv/year.
