안병열 순천향대학교 일반대학원 2024 국내석사

악성코드는 더욱 다양한 난독화 및 분석 우회 기법 적용과 같이 고도화 가 진행되고 있다. 이러한 고도화된 악성코드를 탐지하기 위해 머신 러닝 기반 악성코드 탐지, 시그니처 기반 탐지와 같은 다양한 연구가 이루어지 고 있다. 기존의 시그니처 기반 탐지 방법은 파일의 해시값, Yara Rule 등 기존 존재하는 샘플들의 정보로만 탐지를 수행하기 때문에 고도화된 악성 코드 및 변종의 탐지에는 한계가 있다. 최근에는 CNN(Convolution Neural Network), RNN(Recurrent Neural Network)등 머신러닝 기반의 악성코드 탐지 기법이 주목받고 있으며 이는 정적 및 동적 특징 정보를 활용하여 높은 성능을 보여주지만, 기존 악성코드의 특징 정보를 기반으로 학습 및 탐지를 수행하므로 새로운 악성코드나 변종의 탐지에 있어 한계가 존재한 다. 이를 극복하기 위해 적은 수의 샘플로 효과적인 학습을 진행하고 유사도를 기반으로 예측을 수행하는 FSL(Few-Shot Learning)이 대두되었다. FSL에는 Zero-Shot Learning, One-Shot Learning이 존재하며 대표적인 네 트워크로는 샴 네트워크가 존재한다. 본 논문에서는 바이트 이미지와 Opcode 빈도수 기반 이미지로 구성된 두 가지의 특징 정보로 활용하여 유 사도 기반 학습을 진행하고 각각의 특징 정보마다 생성된 모델에 가중치 를 부여한 후 악성코드 탐지를 수행하여 적은 샘플 및 변종에 대해 효과적인 탐지가 가능한 프레임워크를 제안한다.

안병열 경상대학교 대학원 2005 국내박사

Al_(x)Ga_(1-x)N thin films with x ranging from 0.30 to 0.54 were grown on the Al₂O₃(0001) substrate with AlN buffer layers by using metalorganic chemical vapor deposition (MOCVD). The Al content (x) of Al_(x)Ga_(1-x)N thin films was controlled by adjusting the ratio of TMAl and TMGa. The X-ray diffraction (XRD) spectra showed the wurtzite Al_(x)Ga_(1-x)N thin films had a good crystalline quality and were grown epitaxially on Al₂O₃(0001) substrate. The amount of Al in the Al_(x)Ga_(1-x)N thin films was linearly dependent upon the TMAl and the TMGa flow rate. The thickness of Al_(x)Ga_(1-x)N thin films confirmed through the measuring of cross sectional scanning electron microscopy (SEM) and atomic force microscopy (AFM) was 1.2 ㎛ and the more the Al composition increased, the coarser the film surface became. Dislocation density which seemed to have been formed by the stress relaxation at the AlN/Al₂O₃ interface was increasing with the increase of Al content. Through the measuring of UV-visible spectrometer, photoluminescence (PL) and cathodoluminescence (CL), it was found that as the Al composition of Al_(x)Ga_(1-x)N thin films increased, overall optical properties have dropped decreasing of the intergrated luminescence intensity and increasing of full width at half maximum (FWHM) in the PL and CL spectra. Band gap energy of Al_(x)Ga_(1-x)N thin films increased depending on the increase of Al content, and bowing parameter has been 0.77, which agreed with existent experiment result. As the Al composition increases, the yellow luminescence (YL) peak intensity, related to defects in comparison with near band edge (NBE) peak intensity, has relatively increased. Especially it was found that the Al0.48Ga0.52N thin film showed remarkably inferior optical properties related to the defect and structural properties compared with others. It was confirmed in the analysis through cathodoluminescence indepth spectroscopy (CLIS) that the peak related to Al_(x)Ga_(1-x)N thin films takes place within 1.2 ㎛, and in the depth more than that, Al-O-N-related activators exist in the buffer layer of AlN and the AlN/Al₂O₃ interface. The length scale of spacial distribution of activator by Al composition fluctuation of Al_(x)Ga_(1-x)N thin film is hundreds of nm, and the more Al composition increased, the darker the CL image became.

有機農業技術體系化に關すゐ技術的·經濟的硏究

안병열 神戶大學 1998 해외박사

近年 세계적 관심사의 하나는 地球 環境 問題인데, 溫暖化, 酸性雨, 砂漠化, 生物種의 감소 등 諸問題의 해결을 위하여 여러 가지 論議가 거듭되고 있다. 그 論議의 방향은 大量生産 · 廢棄를 특징으로 하는 오늘날의 諸産業의 生産 構造를 어떻게 環境과 調和 가능한 持續的 産業에 再編成할 수 있는 것인가에 있다. 당연히 近代 農業도 또한 生産 效率 重視로부터 環境重視型農業에 再編成 되지 않으면 안되는 상황에 있다. 世界的으로 環境保全型農業의 重要性이 일컬어지게 되어, 그 典刑이며, 상당한 歷史와 IFOAM(國際有機農業運動聯盟)이라는 國際的 조직을 가지는 有機農業에 대하여 세계적인 關心이 높아지고 있다. 日本에 있어서도 農林水産省은 1992년부터 環境保全型農業의 推進을 정책 방침으로 하는 등, 지금까지의 정책과는 크게 轉煥하는 방향을 제시하였다. 兵庫縣에서는 보다 일찍 진행되어 農業 近代化에 의하여 어쩔 수 없이 破壞 ·變質된 地域 環境의 再創造를 목표로 세우고 環境創造型農業의 推進을 政策 方針으로 하고 있다. 本 論文은 이와 같이 社會的으로 높은 關心을 가지게 된 有機農業을 硏究의 대상으로 有機農業 技術 체계화의 가능성과 구체적 方法 및 그 技術的 ·經濟的 成立 條件을 分析하였다. 그 理由는 近代 農業과는 다르며, 有機農業의 普及 ·擴大가 사회적으로 요구되고 있지만, 有機農業 技術 체계화는 아직까지도 未確立되었기 때문이다. 따라서 新規로 有機農業을 實踐하려고 하는 많은 生産者는 試行錯誤를 거듭하지 않으면 안되었고, 有機農業의 普及 ·擴大를 困難하게 하는 側面이 있기 때문이기도 하다. 제1장에서는 일본에 있어서 有機農業의 展開와 有機農業의 論理를 論述하였다. 有機農業의 思想과 運動은 1971년 日本有機農業硏究會의 誕生을 端緖로 하며, 當時의 사회 상황을 주시한 사상과 운동이 전개되었다. 제2장에서는 有機農業의 生産 實態와 産消提携에 관해서 兵庫縣下 2지역의 有機農業實踐團體의 생산 실태를 조사하여, 그 단체에 소속한 조사 대상 농가의 意識과 유기농업 실천 과정을 밝혔다. 어느 團體도 20명 정도의 생산자가 소속되어 年間 100 品目에 달하는 多品目의 有機農産物을 生産하여 消費者와 직접적인 契約 關係를 맺는 産消提携에 의하여 안정된 가격 조건으로 流通시키고 있었다. 제3장에서는 有機農業에 있어서 土地 利用 方式과 有機農産物의 流通에 관해서 조사 대상자의 事例를 기초로 하여 分析하였다. 토지 이용 방식은 病蟲害 對策과 雜草 對策을 고려하여 混作, 輪作을 주축으로 한 복합적인 토지 이용 및 수도작 이후에는 논밭輪換을 하는 집약적인 토지 이용방식을 전개하고 있었다. 생산된 농산물은 소비자가 年間 안정된 가격으로 全量 인수하는 것이 특징적이며, 동시에 이러한 것들이 기술 체계화를 성립시키는 중요한 경제적 조건으로 되어 있는 것을 究明하였다. 제4장에서는 有機 수조작의 技術 체계화의 가능성과 그 方法에 관하여 考察하였다. 有機農業의 基本 技術은 適正한 有機物의 施用에 의한 흙살리기, 適正한 品目 ·品種의 選擇, 適地適期作, 適正한 水管理, 適切한 土地 利用 등의 技術을 잘 조화시키는 것이었다. 그러나 가장 중요한 것은 발효 有機物(堆肥)을 적정량 토지에 還元하여 耕地 土壤의 改善을 도모하고 地方을 向上시켜 圃場生態系를 적절히 維持하는 것이 필요한 기술적 방책이었다. 이러한 部分 技術을 잘 조화시킨 기술 체계가 안정적인 수도작을 가능하게 하는 것을 檢討하였다. 제5장에서는 前章까지의 기술적인 분석에 입각하여 유기농업 기술 체계화를 可能하게 하는 경제적 조건에 관해서 檢討하였다. 本 論文이 提示하는 有機農業은 環境 保全과 食糧의 安定的 供給 및 今後 新規로 유기농업에 參加할 농가에게 참고가 될 것이며, 環境農業의 普及 ·擴大에 공헌 할 것으로 생각된다.

The survey is based on the reaction of 54 gifted students by way of a questionnaire. They have participated in a specifically designed science education program for brilliant middle school students. The conclusion based on the survey is as follows. 1) Students show their preference for science: 40.4% and mathematics: 39.4% while they are less interested in subjects such as literary, social science and artistic and physical training. 2) 40% of students are motivated to apply for the program on their own while only 30% of them applied for the program usually recommended by their parent or teacher. 3) The survey shows that participants want the program to be operated for 3 hours in the afternoon on weekend. 4) As for the effect of the special program on students personal academic achievement, 83.3 % of them answered, saying It is helpful. 5) Most of the students (69.8%) answered the difficulty level of the program is suitable or a little difficult while 2 students answered very difficult. So, the current difficulty level is considered suitable while the rest 7 students need to be examined for the level. 6) Students have preference for the field trip of heavenly body, which is usually difficult for them to experience. As for collecting data, 89.2% students answered the Internet is most useful. 7) The survey shows that 96.2% students got to have more creative thinking and more careful attitude in observing things. Furthermore, 100% of respondents say they are willing to participate in the next program. In conclusion, the program pays off to develop students interest and aptitude. For example, 46 students (93.9%) want to enter science high school. 8) Most students want to major in science, engineering, medicine, mathematics by priority while 2 of them want to major in other fields. 9) The special education program for brilliant students provides a variety of support and the program makes use of school facilities more than 87.8%. Respondents shows their satisfaction for the circumstances, saying more than average. Therefore, it is important to choose brilliant students in science as early as possible and educate them properly. To do so, it is necessary to continually develop a better program and support the program fully in terms of human resources, management and finance. 본 연구는 2005년부터 경상대학교 영재교육원의 중등반 학급에서 수행하고 있는 과학 영재학습에 대한 영재아 50명의 반응을 설문지 방법으로 조사, 분석하였다. 영재교육을 받고 난 후의 학생들은 창의적인 사고, 사물을 관찰하는 태도, 학습방법 등의 변화를 가져오고 있다. 따라서 영재아들은 영재로서의 잠재성과 능력을 발휘할 수 있는 시기에 맞는 적절한 교육이 필요하다고 본다. 결국 이에 따른 과학영재학습에 있어서 교수학습은 창의적 사고와 자기 주도적 학습능력을 신장할 수 있도록 다양한 방법으로 운영하는 것이 좋을 것으로 사료된다. 과학영재교육은 학생들의 창의성 계발과 도덕성 함양, 그리고 자기 주도적 학습능력을 신장할 수 있고, 장래의 진로를 결정하는 동기가 될 수 있을 뿐만 아니라 기초과학 발전은 물론 국가 경쟁력을 높일 수 있는 인재 양성에도 도움이 되리라고 여겨진다. 그러므로 과학 영재아를 조기에 선발하여 교육하는 것이 무엇보다 필요하다고 여겨진다. 따라서 이를 수행하기 위해서는 영재학습 프로그램의 지속적인 개발과 국가적인 차원에서의 인적, 행. 재정적 지원이 절실히 요구되어진다.

The purpose of this study was to investigate the effect of preference attributes on customers and thinking that satisfying a customers could improve the fast food industry, We wanted to look at the effect on customer satisfaction and revisitability for customers with experience using fast food. Through these attributes of choice, the domestic fast food industry provides useful information and provides directions for the future. The research was conducted with the aim of presenting a desirable development plan for the company to implement. Through the literature study, we reviewed the theoretical background of fast food, choice attributes, customer satisfaction and revisitability to define the concept and examine the association between each variable. In addition, after designing a research model and hypothesis for empirical research, the survey questions were derived and their impact was identified through analysis. To that end, the survey was conducted for six weeks from December 1, 2018 on fast food customers in Seoul and Gyeonggi-do (Including Incheon) through the questionnaire method. A total of 460 copies were retrieved through the survey, and 444 copies were used for empirical analysis, except for the questionnaires that responded insincerely and the questionnaires that resulted in the missing. In summary, the results of this study are as follows. Based on the results of the validation of Hypothesis 1 that predicted that the selection attributes of fast food customers will have a positive impact on customer satisfaction, the brand, menu and service factors that are attributes of fast food customers' choice have all been shown to have a positive effect on customer satisfaction. The more positive the perception of brands, menus and services, the higher the customer satisfaction, indicating that the brands, menus and services of fast food restaurants are the main predictors that positively affect customer satisfaction. Therefore, both the theory of research, 'Brand among customer choice attributes using fast food will affect customer satisfaction' hypothesis 1-1, 'The menu of fast food customers' choice attributes will affect customer satisfaction' hypothesis 1-2 and 'Service will affect customer satisfaction by fast food customers' choice attributes' were adopted 1-3. If you look at the results of the validation of hypothesis 2 which predicts that the selection attributes of fast food customers will have a positive effect on the repeat visits, The positive perception of fast food restaurant brands, menus and services led to higher customer satisfaction, indicating that brands, menus and services of fast food restaurants were the main predictors that positively affect customer satisfaction. Therefore, both the hypothesis that "brand among the characteristics of customers using fast food will affect the degree of revisitability" 2-1, and "menu of fast food customers' choice will affect the degree of return visitation" 2-2 and "services of fast food customers' selectivity will have a positive effect on the return visit" were adopted 2-3. If you look at the results of the validation of hypothesis 3 that customers' satisfaction with fast food will have a positive effect on the revisitability, The higher the level of customer satisfaction among fast food customers, the higher the level of repeat visits, indicating that customer satisfaction at fast food restaurants has a positive effect on revisiting visits. Therefore, research theory 3 was adopted. Therefore, the fast-food industry will have to look for a menu that meets the expectations of fast-food customers and their own differentiated ways to satisfy consumers. The results of the empirical analysis are intended to give the following implications: Theoretical implications were to examine the effects of fast food customers' choice attributes on customer satisfaction and revisitability through analysis of menus, brands and services as variables. It was suggested that the management of menus, brands and services for fast-food customers should come first, but in particular, the menu part should be managed more thoroughly. In addition, if customers are satisfied with the differentiated menus, brand image, and service improvement efforts of each of the rapidly changing fast food businesses, the visitation level will be increased. Through this research, strategies that can enhance satisfaction and revisitability of fast food customers will require development of diverse menus, such as hamburgers, sandwiches, brunchies and beverages tailored to consumption patterns, and efforts to improve brand promotion strategies and systematic service using eco-friendly and natural ingredients, the latest trend. Having a competitive edge in the fast-food industry can cope well with consumer-oriented changes, customers' motivations are paramount and contribute to setting new target markets and marketing strategies in the future.

With the development of high-tech industries, including new materials like ceramics, computers, and other electronic goods, international trade goods are becoming diminutive and high-priced when comparing with the former trade goods. So owners we increasing the use of air cargo so that their goods can be reached their customer rapidly, correctly, and safely. The role and service of air cargo transportation agent we becoming diversification and complication as air cargo is increared and the market size of air cargo enlarged like this. Therefore, the study has put the purpose on securing an ascendancy from a keen competition with foreign transportation enterprises by examining the status and problems of Korean air cargo agents and studying the operating devices to be able to meet the increase of demand of air cargo by improving and enforcing the constitutino of air cargo agent. For this purpose, the study has been developed total 5 chafers. In the chapter Ⅰ, the purpose, the method, and the extend of the study have been mentioned. In the chapter Ⅱ, the role of air cargo transportation agent has been treated. In the chapter Ⅲ, the status and problems on management of Korean air cargo transportation agent have been checked. In the chapter Ⅳ, the improvement devices for the management af air cargo transportation agent have been presented. In the chapter Ⅴ, the result of the study has been mentioned. According to the result of the study, the problems of domestic air cargo agent are as follows. First problem is on small capital and petty business. Second systemetic and active marketing conception is not positioned. So they have much dimculties to cope with a keen market competition and carrier's the policy of a price decrease. Third, the computerization of Air Cargo for a rapid service and the efficiency of management are not arranged. Forth, a various transportation service that owners can use reaseonably is not developed. In order to solve these structural problems that the Korean air cargo transportation business and promote international campetitiveness, the following measures were seriously discussed. First the security of a large scale capital for a large size of agent and of the special institution for the specialization should be achieved. Second, with the change of the recognition of air cargo market, agents should establishing marketing strategy to be able to cope with the diversity of the propensity of consume. Third, a complete computerization should be intrduced in dealing with air cargo in order to increase the administrative efficiency in the business and to secure good quality services for customers. Forth, a various service system for customer should be developed. Lastly, it is being estimated that air cargo transportation will grow as an important transportation system to lead transportation industry trom comming 2,000's. Air cargo transportation agent in persent, however, requires government's aid because it's impossible that they secure a large scale capital and develop system in short times.
