Butyltin compounds, including mono-(MBT), di-(DBT) and tributyltin(TBT) were analyzed in 44 human blood samples randomly collected from a hospital in "K" a city. Gas chromatograph equipped with flame photometric detector(FPD) was used to quantify the amounts of butylin compounds. Method detection limits(MDL) of this analytical method were 3.69ng Sn/g for MBT, 0.91ng Sn/g for DBT and 1.09ng Sn/g wet wt for TBT respectively. Standard reference material(SRM) containing of $1.3{\mu}g/g$ TBT as chloride was analyzed to check if this analytical results would be reliable. Recovery of about 90% was obtained through this analysis, indicating that the analytical method from butyltin compounds blood was reliable. The concentrations of butyltin compounds ranged MDL(<3.69) to 7.93ng Sn/g for MBT and 1.15 to 5.41ng Sn/g wet wt for DBT. Tributyltin was below detection limit in all samples. Detection limits of our results are lower than those reported by Kannan et al. who reported butyltin compounds in 33 human blood samples in the United States. Detection of MBT and DBT on blood sample implies that butyltin compounds could be absorbed through consumption of seafoods or exposure to food stuffs made of plastics and household items. Further study is needed to examine if butyltin compounds in blood can be reliably analyzed and used as intake index.

기존의 음향측심기는 복잡한 하드웨어 구조로 인해 크기와 중량이 큰 단점이 있었다. 이에 본 개발에서는 이러한 단점을 보완하기 위해 고속의 단일칩을 적용하여 단순구조의 하드웨어로 구성하였으며, 그 결과 장비의 크기 및 중량을 감소시킬 수 있었고 또 신호처리 기법을 적용하여 측정 데이터의 안정성을 획득 하였다.

원자력발전소의 운영 목표는 안전하고 효율적으로 설비를 운영하여 양질의 전기를 소비자에게 공급하는데 있다. 시뮬레이터는 설비의 운영에 중추적인 역할을 담당하고 있는 운전원의 작업 숙련도 향상뿐만 아니라 설계도구로 활용되는 중요한 설비이다. 국내 원자력산업계는 연구기관의 주도하에 다수의 시뮬레이터를 개발하였으며 최근에는 일반 산업체를 개발에 참여시키고 있다. 그러나, 시뮬레이터의 하드웨어와 소프트웨어 개발을 위한 관련 요건이 일반 산업체에게 충분히 인식되지 못하여 개발에 어려움을 겪고 있다. 본 연구에서는 시뮬레이터 개발을 위한 소프트웨어 개발요건을 고찰하고 국내 일반 산업체에게 권고되는 개발 참여 전력을 제안한다.

In this study, based on the awareness of the problem of current scientific guard systems of ROKA, We suggested a develoment direction for scientific guard system applying 3 elements of Revolution in Military Affairs by 2035. To this end, we analyzed challenges of current scientific guard systems and reviewed similar cases in other countries. Based on this, We suggested a develoment direction for scientific guard system, comprised of the concept of gurad operation, the organization of guard troops, and MUM-T(manned and unmanned teaming) by applying the framework of 3 elements of military innovation (operation concept, organization, weapon system). In order to overcome challenges at hand, we need a innovative scientific guard systems that applies MUM-T based on high technology along with agile&smart guard troops.
