This study was conducted to provide a basis for developing strategies to improve the intention to quit smoking by identifying the factors affecting the smoking cessation intention of male smokers living in Seoul who have not tried to quit smoking in the past year. The components of the planned behavioral theory were used to identify the influencing factors. The research data were analysed secondary data used in the study performed by the Korea Centers for Disease Control and Prevention in 2020. As a result of the univariate analysis, the factors affecting the smoking cessation intention rate were the average daily smoking amount and the components of the TPB. As a result of multivariate logistic regression analysis, the subjective norm and the perceived behavior control factor among the components of the TPB had statistically significant differences. Therefore, in order to increase the intention to quit smoking, it would be effective to use strategies that strengthen the strong recommendations from significant others and the smoker's self control.

The ship system is complex and advanced, and the operation relationship between each element is very high. So it is necessary to approach it in terms of an overall and integrated system in addition to the traditional sequential approach of finding and removing the direct cause of the accident when analyzing the accident. In this study, it is analyzed the recent fire accidents on ships occurred the Korean terrestrial water using a STAMP methodology that is different from conventional accident analysis techniques. This analysis reviews a range of factors, including safety requirements to prevent fires in ships, inappropriate decisions and actions, situations, equipment defects, and recommendations derived from accident analysis results. Through a comprehensive approach to accident prevention using STAMP, alternative evaluations are presented at the component level within the entire system of ships, and they are systematically used for accident prevention and risk evaluation as well as simple accident analysis.

Article 37 of the International Convention on Civil Aviation requires that rules should be adopted to keep in compliance with international standards and recommended practices established by ICAO. As SARPs are revised annually, each ICAO Member State needs to reflect the new content in its national aviation Acts in a timely manner. In recent years, data-driven international standards have been developed because of the important roles of aviation safety data and information-based legislation in accident prevention based on human factors. The Safety Management System and crew Fatigue Risk Management Systems were reviewed as examples of the result of data-driven rulemaking. The safety management system was adopted in 2013 with the introduction of Annex 19 and Chapter 5 of the relevant manual describes safety data collection and analysis systems. Through analysis of safety data and information, decision makers can make informed data-driven decisions. The Republic of Korea introduced Safety Management System in accordance with Article 58 of the Aviation Safety Act for all airlines, maintenance companies, and airport corporations. To support the SMS, both mandatory reporting and voluntary safety reporting systems need to be in place. Up until now, the standard of administrative penal dispensation for violations of the safety management system has been very weak. Various regulations have been developed and implemented in the United States and Europe for the proper legislation of the safety management system. In the wake of the crash of the Colgan aircraft, the US Aviation Safety Committee recommended the US Federal Aviation Administration to establish a system that can identify and manage pilot fatigue hazards. In 2010, a notice of proposed rulemaking was issued by the Federal Aviation Administration and in 2011, the final rule was passed. The legislation was applied to help differentiate risk based on flight according to factors such as the pilot's duty starting time, the availability of the auxiliary crew, and the class of the rest facility. Numerous amounts data and information were analyzed during the rulemaking process, and reflected in the resultant regulations. A cost-benefit analysis, based on the data of the previous 10 year period, was conducted before the final legislation was reached and it was concluded that the cost benefits are positive. The Republic of Korea also currently has a clause on aviation safety legislation related to crew fatigue risk, where an airline can choose either to conform to the traditional flight time limitation standard or fatigue risk management system. In the United States, specifically for the purpose of data-driven rulemaking, the Airline Rulemaking Committee was formed, and operates in this capacity. Considering the advantageous results of the ARC in the US, and the D4S in Europe, this is a system that should definitely be introduced in Korea as well. A cost-benefit analysis is necessary, and can serve to strengthen the resulting legislation. In order to improve the effectiveness of data-based legislation, it is necessary to have reinforcement of experts and through them prepare a more detailed checklist of relevant variables.

Decommission of medical cyclotron give rise to a lot of low-level radioactive waste and costs. Decommissioning cost should be reasonably calculated according to the decommissioning activities and installed components of facilities. In this paper, we investigated the experience on the cyclotron relocation from SNUH(Seoul National University Hospital) to SKKU(Sungkyunkwan University) and analyzed radioactive waste management costs by applying the disposal scenarios. Also considerations for decommissioning cost estimation are reviewed. The results could be utilized as a basic data for establishment on the methodology of decommissioning cost estimation and evaluation.

This studies have been carried out to find anticrease finishing method other than urea formaldehyde polymerization method which the author had done it with his former report. Acrylic amide polymerization method with water solubility controlling device was developed in this parer and the obtained results are as followings. 1. Poor anticrease silk textile could improve as much as 25% than original fabric. 2. Light density with high twisted silk textiles may improve a few per cent increase of anticrease, because they held good anticrease nature as well as polyester fabric. 3. There was no significant stiffness change after such finish. 4. This finish is recommended to carry after dyeing process either yarn dye or cloth dyeing. 5. The finished textile with this method is recommended to wash with dry cleanning method.

International Telecommunication Union(ITU), recommended a propagation prediction models that can be applied to a various propagation environments that many services have been established in the field of broadcasting and telecommunications using ITU-R. Each propagation prediction models are revised with the complement procedures of an expected difference of channel environment and prepared for a standard of a propagation prediction. In this research, it is possible to realized a practical propagation prediction in each transmitting station for a broadcasting environments of ITU-R Rec. P.1546-3 model, so called the point-to-area, using supplementary parameters of the transmitting station specification.

Randomness is a basic security evaluation item for the most cryptographic algorithms. NIST has proposed a statistical test suit for random number generators for cryptographic applications in the process of AES project. However the test suit of NIST is customized to block ciphers which have the same input and output lengths. It needs to revise NIST's test suit for key derivation functions which have multiple output blocks. In this paper we propose a revised method of NIST's statistical randomness test adequate to the most key derivation functions and some experimental results for key derivation functions of 3GSM and NIST.

이 논문에서는 관계형 데이터베이스 모델 기반의 OWL 웹 온톨로지 모델을 보이고 이에 대한 실험 및 비교 평가 결과에 대하여 기술한다. OWL은 W3C에 의해 2004년 12월에 권고안으로 채택된 이후에 많은 연구가 진행되고 있다. 편집 도구 개발, 저장소 개발로 OWL 기반의 추론 엔진까지 이와 관련된 다양한 연구가 진행 중이다. 특히 OWL 온톨로지의 영구적인 저장 및 관리를 위해 관계형 데이터베이스 모델을 이용한 많은 연구 결과들이 발표되고 있다. 이 논문에서는 널리 알려진 관계형 모델 기반의 저장소 보다 나은 성능을 제공하기 위해 제안한 모델에 대한 평가 결과에 대하여 기술한다. 기존 유사 연구의 경우, 비교 평가를 위한 평가 항목으로 온톨로지 로드 시간을 고려하기도 하지만 이 논문에서는 질의응답 시간에만 초점을 둔다. 이는 매우 특수한 상황을 제외한 대부분의 상황에서 질의 처리 시간이 가장 중요한 요소이며 실질적인 활용성 측면에서 핵심적으로 다루어야 하는 평가 항목이기 때문이다. 실험을 위한 데이터로서는 많은 연구에서 활용하고 있는 LUBM 데이터 셋을 이용하며 실험 대상으로는 오픈 소스이며 널리 알려진 시스템인 Jena의 저장소와 Sesame를 이용한다. 실험 및 비교 평가 결과, 제안 시스템이 비교 대상 시스템들에 비해 나은 성능을 보임을 알 수 있다.
