Threat Evaluation(TE) which has air intelligence attained by identifying friend or foe evaluates the target's threat degree, so it provides information to Weapon Assignment(WA) step. Most of TE data are passed by sensor measured values, but existing techniques(fuzzy, bayesian network, and so on) have many weaknesses that erroneous linkages and missing data may fall into confusion in decision making. Therefore we need to efficient Threat Evaluation system that can refine various sensor data's linkages and calculate reliable threat values under unpredictable war situations. In this paper, we suggest new threat evaluation system based on information fusion JDL model, and it is principle that combine fuzzy which is favorable to refine ambiguous relationships with bayesian network useful to inference battled situation having insufficient evidence and to use learning algorithm. Finally, the system's performance by getting threat evaluation on an air defense scenario is presented.

Aspect-oriented programming is the paradigm which extracts crosscutting concern from a system and solves scattering of a function and confusion of a code through software modularization. Existing aspect developing method has a difficult to extract a target area, so it is not easy to apply aspect mining. In an aspect minning, it is necessary a technique that convert existing program refactoring elements to crosscutting area. In the paper, it is suggested an aspect mining technique for extracting crosscutting concern in a system. Using abstract syntax structure specification, extract functional duplicated relation elements. Through Apriori algorithm, it is possible to create a duplicated syntax tree and automatic creation and optimization of a duplicated source module, target of crosscutting area. As a result of applying module of Berkeley Yacc(berbose.c) to mining process, it is confirmed that the length and volume of program has been decreased of 9.47% compared with original module, and it has been decreased of 4.92% in length and 5.11% in volume compared with CCFinder.

Adversarial attack, which geneartes adversarial data to make target model misclassify the input data, is able to confuse real life applications of classification models and cause severe damage to the classification system. An Black-box adversarial attack learns a substitute model, which have similar decision boundary to the target model, and then generates adversarial data with the substitute model. Jacobian-based data augmentation is used to synthesize the training data to learn substitutes, but has a drawback that the data synthesized by the augmentation get distorted more and more as the training loop proceeds. We suggest data augmentation with 'decay factor' to alleviate this problem. The result shows that attack success rate of our method is higher(around 8.5%) than the existing method.

This study aimed to identify the components of the nurses' exposure experiences and clarify the semantic structure of nurses by analyzing the participants' experiences of exposure to radiation. The participants in this study were nine nurses who worked for at least six months in the operating room of a City General Hospital. The data were collected using in-depth interviews and analyzed using the phenomenological method by Giorgi's (2004). As a result, six components were derived: "worrying about the disease by repeated radiation exposures", "exhausting physically and mentally," "trying to protect themselves against radiation exposure", "feeling of internal confusion and conflict", "demanding improvement of work environment", and "accepting and adapting to reality". In conclusion, nurses participating in radiation exposure surgery are concerned about the possibility of disease, experience physical and mental fatigue, and then consider changing their occupation. On the other hand, they try to accept and adapt to reality by considering the possibility of a job change or trying to protect themselves from the harsh environment. To develop a radiologically safe environment, systematic and effective resolutions must be secured at the organizational level.

The purpose was to analyze the trend of sport pedagogy in secondary teacher certification examination based on the secondary teacher qualification criterion in Korea Institute for Curriculum and Evaluation since abolition of multiple-choice questions from 2014 to 2020. The result showed the questions for sport pedagogy were 48 question since 2014, and found 83 sub-questions. The implications are as follows. First, the frequency of sub-questions in sport pedagogy has increased, causing an integrated question. Second, the serious unbalanced issue of questions for examination was presented. Third, dependence on specific domains was excessively high. Fourth, the confusion caused by the overlapped domains with the content knowledge of physical education subject was intensified. Therefore, evaluation factors based on 2016 KICE classification table should be clear and field application questions should be developed.

One of the important use of piles is to furnish lateral support and nowadays it is getting highlighted due to the increase of skyscrapers, transmission towers, wind turbines, and other lateral action dependent structures. After Broms (1964), many researchers have suggested methods for estimating lateral capacity of pile. But each method assumes different earth pressure distribution and lateral earth pressure coefficient causing confusion on the part of pile designers. Lateral earth pressure, essential in lateral capacity estimation, is influenced by pile's rotational behavior under lateral load. Prasad and Chari (1999) assumed the rotation point of pile and suggested an equation of ultimate lateral load capacity. In this study, we investigate the depth of rotation point in both homogeneous soil and multi layered soil, and compare with the estimation value by previous research. Test results show that measured rotation point and estimated value by Prasad and Chari's equation show good agreement and multi layered condition affects the location of rotation point to be changed.

The Purpose of this study was to explore the methods of generalization and errors pattern generated by mathematically gifted students and non-gifted students in elementary school. In this research, 6 problems corresponding to the x+a, ax, ax+c, $ax^2$, $ax^2+c$, $a^x$ patterns were given to 156 students. Conclusions obtained through this study are as follows. First, both group were the best in symbolically generalizing ax pattern, whereas the number of students who generalized $a^x$ pattern symbolically was the least. Second, mathematically gifted students in elementary school were able to algebraically generalize more than 79% of in x+a, ax, ax+c, $ax^2$, $ax^2+c$, $a^x$ patterns. However, non-gifted students succeeded in algebraically generalizing more than 79% only in x+a, ax patterns. Third, students in both groups failed in finding commonness in phased numbers, so they solved problems arithmetically depending on to what extent it was increased when they failed in reaching generalization of formula. Fourth, as for the type of error that students make mistake, technical error was the highest with 10.9% among mathematically gifted students in elementary school, also technical error was the highest as 17.1% among non-gifted students. Fifth, as for the frequency of error against the types of all patterns, mathematically gifted students in elementary school marked 17.3% and non-gifted students were 31.2%, which means that a majority of mathematically gifted students in elementary school are able to do symbolic generalization to a certain degree, but many non-gifted students did not comprehend questions on patterns and failed in symbolic generalization.

지난 6월 3일 동경에서 있었던, 아시아 항공/우주법 학술대회 제 3분과에서 영국 Bin Cheng교수의 "The Warsaw System: Mess up, Tear up, or Shore up?"이라는 주제의 논문발표가 있었다. Bin Cheng교수는 특히 유럽의 EC Consultant Paper 와 일본항공사들의 1992년의 무한책임보상주의 채택에 대하여, 마치 무한 책임보상주의의 이론이 승리하였으며, 위의 상황들이 그 시작이라고 단정하였는데 이러한 견해는 아직까지 시기상조라고 생각한다. 본 글에서는 동경회의에서의 Bin Cheng교수의 논문중 특히 10항의 결론 부분을 중점으로 반대되는 의견을 제시하고자 한다. 국제항공사법인 와르소체제가 과연 발전하고 있는 것인가? 퇴보하고 있는 것인가? 와르소체제의 반대론자들은 미국의 소송변호사들, 일본항공사들과 일부 순수이론을 고수하는 학자들로써 이들은 와르소체제로부터의 탈퇴와 무한책임보상주의를 고수하고 있다. EC Consultation Paper (각주 122 참조)에서 보듯이, 비록 항공운송시의 손해배상액이 타 운송시의 손해배상액보다 적기는 하지만 이것이 곧 '무한책임보상주의'를 의미하는 것은 아니다. 미국의 판례중 불법행위로 인한 소송 (Nichole Fortman v. Hemeo Inc.)에서 보면, 작은 창자의 대부분을 병원의 과실때문에 잃은 Brooklin의 한 여인에게 500억 정도의 손해배상이 주어진 것을 보면, 과연 완전 보상에 맞는 무한책임이 과연 항공소송에 적용될 수 있는 것인가를 알아야 한다. 무한책임보상주의는 특히 개발도상국의 항공사들에게 보험료가 너무 과중하고, 와르소협약의 근본목적인 국제항공법의 통일성에 반하고 있기 때문에 국제사회 전반에 적용하기에는 비현실적이다. 와르소체제의 통일 성에 대한 거부는 만약 와르소체제에 버금가는 다른 보상체제가 있는 경우에는 다르지만, 현실적으로는 결국 국제적 혼란만을 야기사킬 것이다. 또한 와르소체제 반대자들은 항공운송인과 승객들의 관계를 갈등관계로 보고 있지만, 근본적으로 와프소협약에서의 항공운송인파 승객들의 관제는 공동이악관계로 보아야 한다. 항공운송사업의 목적도 또한 이윤추구인 바, 승객들이 항공운송인에게 과다한 손해배상을 요구하면, 결국 항공운송인은 승객들의 주머니에서 그 댓가를 찾으려고 할 것이다. 절국 양자의 이익을 보는 것은 소송변호사들 뿐이라고 볼 수 있다. 또한 'Unlimited Liability' 에서 'Unlimited' 란 'Full-Compensation' 을 의미하는 것으로, 'Wilful-Misconduct' 의 경우에는, 'Full-Compensation' 의 개념과 다르게, 그 보상액이 Warsaw협약 제 22조 1항에 적용되지 않는 'No-limited' 의 개념으로 해석하여야 한다. 항공소송의 경우에 통상 'Wilful-Misconduct' 의 경우에 손해배상액이 약 $700,000 인 것을 보더라도 'Full-Compensation'의 의미로 해석할 수 없다. 몬트리올 제 3추가의정서에서 'WilfulMisconduct' 의 개념을 삭제하고자 하는 것은, 이에 대비하여 추가보상제도, 임액수의 종액, 영격책임추의 등의 요소들을 전제로 하고 있기 때문이다. 몬트리올 제 3추가의정서가 최근의 발전적인 손해배상제도인가에 대하여, Bin Cheng 교수는 반대를 하고 있지만, 최선의 제도를 찾는 입장에서 몬트리올 추가 의정서는 여러가지로 부족하다. 그러나, 유한책임제도의 개선, 엄격책임주의의 도입, 빠른 소송타결의 제도, 재판관할권의 확대 그리고, SDR 화폐단위의 채택 등은 헤이그 의정서 이후의 보다 나은 제도적 장치를 하고 있다고 해석하여야 할 것이다. 시대의 변화에 따라 점진적으로 발전된 보상제도를 채택하였다면, 오늘날과 같이 시대에 뒤떨어진 보상체제로 혼란을 겪고 있지 않았을 것이다.
