In this paper, analyzes the characteristics of self-weight consolidation on the dredged clay according to the fines content and falling height. Research was performed with the dredged clay sampled by Sae-mangeum field site. Classification of fines content was performed by sieve analysis test. After adjusting the fine content, self-weight consolidation tests were carried out focussing on the variation of fines content and falling heights. From the test results of the self-weight consolidation test, samples with high fines content had reached sedimentation completion more later than ones with less fine content samples. In other words, the start of self-weight consolidation was slowing down with increasing of fines content. Also, from the test results of calculating the coefficient of sedimentation consolidation, the coefficient value were increased with the fines content increases. In addition, the change of sedimentation ratio and volume ratio showed more higher changed value as the fine content increases. Thus, it is important to consider the fines content when estimate the settlement time of dredged soil in field dredge work.

「김씨열행록」의 서사적 전통과 소설적 변용

김진영 ( Kim Jin-young ) 동국대학교 한국문학연구소 2020 한국문학연구 Vol.0 No.62

이 글은 ‘첫날밤 신랑 피살형’ 설화를 계승한 「김씨열행록」의 소설적 변용과 그 의미를 살핀 것이다. 먼저 ‘첫날밤 신랑 피살형’ 설화를 유형화 하고, 「김씨열행록」이 어떠한 유형에 초점을 두어 소설적으로 변용되었는지 살폈다. 이를 바탕으로 소설적 변용과 문학사적 의의를 검토하였다. ‘첫날밤 신랑 피살형’ 설화는 여성인물인 며느리를 중심으로, 순절형·수절형·열부형으로 유형화할 수 있다. 순절형은 며느리의 죽음이, 수절형은 며느리의 생존과 활약이, 열부형은 신랑과 신부의 생존과 활동이 중심을 이룬다. 순절형은 유일한 생존 인물인 시아버지를 중심으로 작화한 「사명당전」에서, 수절형은 생존한 며느리와 그 아들 중심의 작화로 「조생원전」·「성부인전」·「김씨열행록」·「주유옥전」에서, 열부형은 며느리와 남편을 살려 작화한 것으로 신소설 「구의산」에서 의미 있게 계승했다. 「김씨열행록」의 소설적 변용에서 주목되는 곳은 작품의 후반부이다. 이 부분을 통해 이야기에 큰 변화가 생기기 때문이다. 이 부분에서 평면성에서 입체성으로, 몰개성에서 개성으로 인물이 변화하고, 사건에서도 불행과 행복의 단순한 구조에다 같은 구조를 다시 한 번 덧씌움으로써 이야기가 복잡해진다. 주제의 경우 효열만을 강조했던 전반부와는 달리 선악의 대립을 통한 권선징악과 유교적인 부귀공명이 부각되도록 했다. 이것은 소설적인 기법이 그만큼 고도화되어 나타난 현상일 수도 있지만, 이질적인 소설의 하위유형을 짜깁기한 결과일 수도 있다. 「김씨열행록」이 간행된 때는 1928년으로, 이때는 같은 설화를 계승한 고전소설 「조생원전」·「성부인전」·「주유옥전」·「사명당전」이 이미 필사되었고, 신소설 「구의산」도 간행된 뒤이다. 그런데 이 작품은 가장 늦게 간행되었음에도 불구하고 고전소설의 작법을 충실히 따르고 있다. 그것도 인과적인 논리보다는 흥미소를 짜깁기한 방식으로 새롭게 창작하였다. 한편 이 작품은 전반부의 여성영웅소설적인 모습과 후반부의 가정소설·남성영웅소설적인 양상, 그리고 전후반부에 나타나는 송사소설적인 실태가 주목된다. 이는 당시에 인기 있던 고전소설의 유형을 교조적으로 수렴·재편한 것이라 하겠다. This article examines the novel development and meaning of Kim's Yeol Haeng-rok, which succeeds the story of ‘First Night Groom Killing’. First, I've typized folk tales, and looked at what type of story Kim's Yeol Haeng-rok was focused as a novel. Based on this, the changes of the novel and the significance of literary history were examined. The story of “The First Night Groom Killing Type” can be divided into martyred type, maintaining integrity type, virtuous woman type, with a focus on female brides. The martyred type is based on the death of the bride, the maintaining integrity type is based on the survival and activity of the bride, and the irtuous woman type is mainly based on the survival and activity of both the groom and bride. The martyred type was created mainly by the father-in-law who was the only surviving person, which is shown at Samyeongdang-jeon. The maintaining integrity type was based on the surviving bride and son. Josaengweon-jeon Seongbuin-jeon Kim's Yeol Haeng-rok, Juyuok-jeon is the representative piece. And the virtuous woman type was made using the bride and husband, and was significantly successful with new-style novel Gueusan. The latter part of the work is noted in the novel variation of Kim's Yeol haeng-lok. This is a big change in the story. The story is complicated by the characters changing from flatness to three-dimensionality, from deviance to individuality, and overwriting the same structure on the simple structure of misery and happiness in events. In the case of the theme, it added the didactic morality and confucian rich resonance through the opposition of good and evil in the first half, which emphasized only filial duty and virtuous thing. It may be the phenomenon of novel techniques, but it may be the result of mending the subtypes of heterogeneous novels. In 1928, Kim's Yeol Haeng-rok was produced, and the classic novels Josaengweon-jeon, Seongbuin-jeon, Juyuok-jeon and Samyeongdang-jeon were already produced. However, despite the latest production, the work faithfully follows the writing of classical novels. It is also a new way of making interests rather than causal logic. On the other hand, this work focuses on the female hero novels in the first half, the home novels and male hero novels in the second half, and the litigarion novels in the total situation. This is a convergence and reorganization of the types of classic novels that were popular at the time.

Orthodontic treatment for middle-aged patients has become more commonplace with various reasons including improved socioeconomic status. Understanding of oral status and treatment modalities of middle-aged patients is mandatory for accurate diagnosis and proper treatment planning. This study investigated 100 consecutive patients aged 40s and 50s and 100 aged 20s who had been examined and diagnosed at the Department of Orthodontics, Chonnam National University Dental Hospital. The results were obtained as follows; 1. Gender distribution showed female outnumbered male patients in young-aged adult patients, but middle-aged patients showed similar male and female distribution. 2. The major concern seeking orthodontic treatment was esthetics not only in young-aged but also in middle-aged adult patients, and a number of middle-aged patients were concerned about oral health as well. 3. Considerable number of middle-aged patients were referred by other dental specialties while young-aged adult patients were more self-motivated for orthodontic treatment. 4. Middle-aged adult patients had more missing teeth and periodontal disease than young-aged adults. 5. The most frequently-observed problem was dental spacing in middle-aged patients while dental crowding in young-aged adult patients. Middle-aged patients showed higher prevalence of deep overbite and overjet while most of young-aged adults presented opposite direction of problem in overbite and overjet. 6. Limited orthodontic treatment was required rather than comprehensive treatment in middle-aged patients, and the most common tooth moving area was anterior part of dentition in case of limited treatment. Need of interdisciplinary therapy with other dental specialties was more common in middle-aged patients. 7. Intervention of specific technique such as invisible TP, passive bracketing, passive wire bonding, and lingual orthodontics was more required in middle-aged patients. Considering that middle-aged patients have different characteristics than young-aged adults, the results of the present study suggest that different treatment modalities are required in middle-aged orthodontic patients in order to manage them properly and efficiently.

다중 대체법은 표본조사에서 결측값이 발생하였을 때 가장 흔히 사용하는 방법이다. 이 방법은 여러 요인에 의해 그 성능이 좌우되며 특히 이상점의 영향을 많이 받는다. 본 연구에서는 가중치 보정법을 이용하여 이상점의 영향력을 줄여 다중 대체법의 성능을 향상시키는 방법을 연구하였다. 가중치 보정법을 이용하여 얻어진 최종 가중치를 다중대체에 사용하였으며 SAS의 PROC MI가 다중 대체를 위해 사용되었다. 모의실험과 매월노동통계 자료를 이용한 실제 자료 분석을 통하여 제안된 방법의 우수성을 확인하였다. Imputation is a commonly used method to handle missing survey data. The performance of the imputation method is influenced by various factors, especially an outlier. The removal of the outlier in a data set is a simple and effective approach to reduce the effect of an outlier. In this paper in order to improve the precision of multiple imputation, we study a imputation method which reduces the effect of outlier using various weight adjustment methods that include the removal of an outlier method. The regression method in PROC/MI in SAS is used for multiple imputation and the obtained final adjusted weight is used as a weight variable to obtain the imputed values. Simulation studies compared the performance of various weight adjustment methods and Monthly Labor Statistic data is used for real data analysis.

Seismic qualification of the Air Cleaning Units for nuclear power plant Ulchin 5&6 has been performed with the guideline of ASME Section III and IEEE 344 code. By using the structural and geometrical similarity analysis, the three models to be analyzed are condensed into a single model and, at the same time, the excitation forces and other operating loads for each model are encompassed with respect to different loading conditions. As the fundamental frequencies of the structure are found to be less than 33Hz, which is the upper frequency limit of the seismic load, response spectrum analysis using ANSYS is performed in order to combine the modal stresses within the frequency limit. In order to confirm the structural and electric stability of the major components, modal analysis theory is adopted to derive the required response spectrum at the component locations. As the all combined stresses obtained from the above procedures are less than allowable stresses and no mechanical or electrical failures are found from the seismic testing, the authors confirm the safety of the nuclear equipments Air Cleaning Units studied in this paper.

The quality of brazing joints is one of the most important factors that have an effect on the performance of the brazing joint-based heat exchangers with the growing use in industry recently. Therefore, it is necessary to inspect the brazing joints in order to guarantee the performance of the heat exchangers. This paper presents a non-destructive method to inspect the brazing joints of the heat exchangers using X-ray. Firstly, X-ray cross-sectional images of the brazing joints are obtained by using CT (Computerized Tomography) technology. Cross-sectional image from CT is more useful to detect the inner defects than the traditional transmitted X-ray image. Secondly, the acquired images are processed by an algorithm proposed for the defect detection of brazing joint. Finally, two types of brazing joint are examined in a series of experiments to detect the defects in brazing joints. The experimental results show that the proposed algorithm is effective for defect detection of the brazing joints in heat exchangers.

현재 국내외에서 제공되고 있는 기후변화 시나리오 자료의 경우 일단위로 제공되고 있다. 그러나 수문 설계 및 계획 시 중요한 입력자료 중 하나는 시간단위 강우 자료로서 기후변화 시나리오에 따른 수자원 변동성을 평가하기 위해선 신뢰성 있는 상세화 기법이 필요하다. 국내외에서는 일단 위에서 일단위로 상세화 하는 기법, 또는 공간상세화 기법 연구는 다수 진행된바 있는 반면, 시간단위 상세화 기법 연구는 일단위 연구에 비해 상대적으로 미진한 실정이다. 이러한 점에서 본 연구에서는 기후변화 시나리오에 따른 영향 평가가 가능한 자료생성을 위해 Conditional Copula 모형을 활용하여 극치시간단위 강우량 상세화 기법을 개발하였으며, 미래 RCP 8.5 시나리오를 활용하여 연대별 극치시간강우량을 생성하였다. 생성된 결과는 우리나라 기상청 지점별로 빈도해석을 통해 결과를 제시하였으며, 본 연구결과는 수자원 분야에서 미래 기후변화 영향을 평가하기 위한 기초자료로 활용 될 수 있을 것으로 기대된다. Climate change projections for precipitation are in general provided at daily time step. However, sub-daily precipitation data is necessarily required for hydrologic design and management. Thus, a reliable downscaling model is needed to analyze impact of climate change on water resources. While daily downscaling models have been widely developed and applied in hydrologic and climate community, hourly downscaling models have not been properly developed. In this regard, this study aims at developing a hourly downscaling model that can better reproduce sub-daily extreme rainfalls using conditional copula model. The proposed model was applied to generate extreme rainfalls under the RCP 8.5 scenario for weather stations in South Korea, and design rainfalls were then finally provided. We expected that the future design rainfalls can be used for baseline data to evaluate impact of climate change on water resources.

김진영,심이삭,윤성훈,Kim, Jin-Young,Sim, Isaac,Yoon, Sung-Hoon 한국인터넷방송통신학회 2021 한국인터넷방송통신학회 논문지 Vol.21 No.4

As the parallel computing capability for artificial intelligence improves, the field of artificial intelligence technology is expanding in various industries. In particular, artificial intelligence is being introduced to process data generated from IoT sensors that have enoumous data. However, the limitation exists when applying the AI techniques on IoT network because IoT has time series data, where the importance of data changes over time. In this paper, we propose time-weighted and user-state based artificial intelligence processing techniques to effectively process IoT sensor data. This technique aims to effectively classify IoT sensor data through a data pre-processing process that personalizes time series data and places a weight on the time series data before artificial intelligence learning and use status of personal data. Based on the research, it is possible to propose a method of applying artificial intelligence learning in various fields. 인공지능을 위한 병렬연산 능력이 향상됨에 따라 인공지능 적용 분야가 다양한 방향으로 확대되고 있다. 특히 방대한 데이터를 처리해야 하는 IoT센서의 데이터를 처리하기 위해 인공지능이 도입되고 있다. 하지만 시간에 따른 데이터의 중요도가 달라지는 IoT 시계열 데이터 특성상 기존의 인공지능 학습 기법을 그대로 적용하기에는 한계점이 있다. 본 과제에서는 IoT 센서 데이터를 효과적으로 처리하기 위해 시간가중치기반 및 사용자 상태값 기반 인공지능 처리기법을 연구한다. 상기 기법을 통해 기존 인공지능 학습을 적용시키는 것 보다 높은 센서 정확도를 확보 할 수 있게 된다. 이에 더해, 해당 연구를 기반으로 다양한 분야에서 인공지능 학습을 적용하는 방안을 제시하고, 지속적인 연구를 통해 다양한 분야로의 확장을 기대할 수 있다.

조선전기의 여계문학(女戒文學)과 충암 김정 부인의 절행(節行)

This thesis is studied about Kim-jeong’s wife, Song’s dying in defense of her chastity and its meaning. First, women’s enlightenment and their literature during the early days of the Joseon Dynasty are examined, and reviewed Mrs song"s background of dying in defense of her chastity and remaining faithful to her husband. Then the meaning of Mrs song"s dying in defense of her chastity is considered synthetically. So far, discussed things are summarized as follows First, it is examined women’s enlightenment and their literature during the early days of the Joseon Dynasty. In the early of the Joseon Dynasty, the rulers that believed in Confucianism strengthened governmental management philosophy with new ideology. So the order of confucian and order of men and women are strengthened newly. So this the woman"s economic rights are much intimidated, and wearing thin remarriage. Woman are recognized not a person of the protection but the object of the ownership, and that is educated very hard. Second, it is considered Mrs song"s background of dying in defense of her chastity and its fact. Mrs song was very different from others in that day. She grew a man of high repute home, and got married a great house. Besides her husband made his entrance into office, so was required to behavior of that image. Because the noble family that both her parents" home and her husband"s home are seek ideology of Neo-Confucianism, and her husband is a politician who puts stress on just and great cause, justify of serving but a single husband is strengtened. Mrs song"s dying in defense of her chastity is summarized growth and development, dying in defense of her chastity and result. That is the birth of noble family, having a good manners with a confucian education, her husband"s dying for great cause and her dying in defense of her chastity. Third, it is considered about a meaning of Mrs song"s behavior. Mrs song"s behavior deeply affected and handed down domestically and socially. First, Mrs song"s dying in defense of her chastity is taken the lead national ethics as a woman of the gentry. And Mrs song"s dying in defense of her chastity is improved an honor to her family. Especially she made her husband to a loyalist, and made herself a virtuous woman, so raised the family"s honor. And then Mrs song"s dying in defense of her chastity is reported a historical literature, so it became an example to woman of the gentry or her family. It is entirely possible that Mrs song"s dying in defense of her chastity is quite similar to women’s enlightenment literature of those days.

초전도 Pipelined Multi-Bit ALU에 대한 연구

김진영,고지훈,강준희,Kim, Jin-Young,Ko, Ji-Hoon,Kang, Joon-Hee 한국초전도학회 2006 Progress in superconductivity Vol.7 No.2

The Arithmetic Logic Unit (ALU) is a core element of a computer processor that performs arithmetic and logic operations on the operands in computer instruction words. We have developed and tested an RSFQ multi-bit ALU constructed with half adder unit cells. To reduce the complexity of the ALU, We used half adder unit cells. The unit cells were constructed of one half adder and three de switches. The timing problem in the complex circuits has been a very important issue. We have calculated the delay time of all components in the circuit by using Josephson circuit simulation tools of XIC, $WRspice^{TM}$, and Julia. To make the circuit work faster, we used a forward clocking scheme. This required a careful design of timing between clock and data pulses in ALU. The designed ALU had limited operation functions of OR, AND, XOR, and ADD. It had a pipeline structure. The fabricated 1-bit, 2-bit, and 4-bit ALU circuits were tested at a few kilo-hertz clock frequency as well as a few tens giga-hertz clock frequency, respectively. For high-speed tests, we used an eye-diagram technique. Our 4-bit ALU operated correctly at up to 5 GHz clock frequency.
