Purpose To examine the technical considerations of endovascular treatment for aortoiliac occlusive disease (AIOD) based on a 10-year experience in Songklanagarind Hospital. Materials and Methods This retrospective cohort study included 210 patients who underwent endovascular treatment for symptomatic AIOD between January 2010 and December 2020. The patients' clinical and lesion characteristics, including technical considerations of the procedure, were collected, analyzed, and stratified using the Transatlantic Inter-Society Consensus (TASC). Results Most patients (80%) in this study had chronic limb-threatening ischemia lesions, with an occlusion rate of 37%. The technical success rate of TASC C & D was lower than that of TASC A & B, 84.4% vs. 99.2% p ≤ 0.001. A technical success rate of 93.3% (14/15) was found for the femoral and brachial approach, compared with a success rate of 89.0% (57/64) for the unibifemoral approach in TASC C & D, without a statistically significant difference (p = 0.076). However, the puncture site complications in this route were up to 17.6%, which is the highest rate compared with other techniques. These complications could be treated either conservatively or minimally invasively. Conclusion In cases of failed femoral access, simultaneous femoral and brachial approaches improved the technical success rate of endovascular recanalization of TASC C & D aortoiliac occlusions.

게임 기획은 초기 기획과 세부 기획으로 나뉘어진다. 초기 게임 기획에는 디자인적인 요소, 기술적인 요소, 마케팅적인 요소등이 효율적으로 고려되어야 한다. 특히 기술적인 요소 즉 플랫폼, 게임 엔진, 서버 구축 및 구성등은 개발 비용과 개발 기간에 영향을 줄 수 있다. 그러므로 게임을 기획할 때 해당 게임의 기획 의도에 적합한 기술 요소를 선택해야 한다. 본 논문에서는 게임을 초기 기획할 때 고려해야 할 기술적인 요소들을 플랫폼, 게임 엔진, 게임 서비스, 그리고 네트워크 인프라를 중심으로 연구하였다.

The several water resources are showed recently the various pollution types due to the industrialization and the disarranged district development. The living waste water, plant waste water and so are contaminated continuously and the recycling water is concerned highly to save the cost and to improve the environment as the general people. The dust and the heavy metal in the air and the acid rain are contaminating the river water and the underground water. The clean environment is on the rise to the general people and is to be the social problems. There is going to complement and repair the water supplying and fire extinguishing pipeline to save the construction cost and improve the environment in the construction facilities parts. Therefore, in this paper the recycling water treatment/supply apparatus using the living waste water is considerated technically and is raised on the practical uses.

Instrumentation and control systems in nuclear power plants have been digitalized for the purpose of maintenance and precise operation. This digitalization, however, brings out issues related to cyber security. In the most recent past, international standard organizations, regulatory institutes, and research institutes have performed a number of studies addressing these systems cyber security.. In order to provide information helpful to the system designers in their application of cyber security for the systems, this paper presents methods and considerations to define attack vectors in a target system, to review and select the requirements in the Regulatory Guide 5.71, and to integrate the results to identify applicable technical security control requirements. In this study, attack vectors are analyzed through the vulnerability analyses and penetration tests with a simplified safety system, and the elements of critical digital assets acting as attack vectors are identified. Among the security control requirements listed in Appendices B and C to Regulatory Guide 5.71, those that should be implemented into the systems are selected and classified in groups of technical security control requirements using the results of the attack vector analysis. For the attack vector elements of critical digital assets, all the technical security control requirements are evaluated to determine whether they are applicable and effective, and considerations in this evaluation are also discussed. The technical security control requirements in three important categories of access control, monitoring and logging, and encryption are derived and grouped according to the elements of attack vectors as results for the sample safety system.
