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.

이현정(Hyeon-Jung Lee),김진영(Jin-Young Kim),조진형(Jin-Hyoung Cho),황현식(Hyeon-Shik Hwang) 대한치과의사협회 2010 대한치과의사협회지 Vol.48 No.5

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.

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.

This study outlines the housing consciousness and needs of single woman household. In order to analyze housing consciousness of single woman household, surveys were conducted with the questionnaire composed of housing consciousness, housing needs, socio-demographic and housing characteristics of single woman household who lived in Seoul, and other near metropolitan area such as Gyeonggi and Incheon. The result of the study shows that single woman household put importance on safety, privacy, and comfort of their indoor housing environment. For single woman households convenience in transportation and facilities for leisure time were one of the important conscious factors. Housing consciousness of single woman household can be categorized into mainly three groups: (i) indifferent to overall housing consciousness except for convenient services such as front desk service at the lobby and maid house keeping services; (ii) privacy conscious group - this was the majority; (iii) relatively active housing consciousness group. Each type had different preference factors when selecting a house. That is, each showed difference preferences when considering types, sizes and services as well as motives for choosing a house.

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.

김진영,조형석,Kim, Jin-Young,Cho, Hyung-Suck 한국광학회 2002 한국광학회지 Vol.13 No.4

유연부품은 조립 시에 변형이 발생하기 때문에 로봇을 이용한 자동조립에서 이의 성공적인 조립을 위해서는 부품변형 및 상대오차를 효과적으로 측정할 수 있는 방법이 필요하다. 이에 본 논문에서는 시각센서를 이용하여 상대오차 및 부품변형을 측정할 수 있는 3차원 측정시스템의 설계방법을 제안한다. 시스템의 광로해석을 통해 실제 작업공간과 카메라 영상면 사이의 사상관계를 해석하고, 이를 토대로 시스템의 설계방법을 제안한다. 또한 구현된 실제 시스템을 이용한 조립실험을 통해 제안된 시스템의 유효성을 검증한다. Unlike rigid parts, flexible parts can be deformed by contact force during assembly. In robotic assembly, information about their deformation as well as possible misalignment between the holes and their respective mating parts is essential for successful assembly. This paper presents a method to design a visual sensing system for measuring parts deformation and misalignment in flexible parts assembly. This paper performs ray-trace analysis of the system. A series of experiments for flexible parts assembly by using the implemented system are performed.

김진영,이승재,정석,박민수,강천구,임한상,김재삼,Kim, Jin-Young,Lee, Seung Jae,jung, Suk,Park, Min-Soo,Kang, Chun-Goo,Im, Han-Sang,Kim, Jae-Sam 대한핵의학기술학회 2015 핵의학 기술 Vol.19 No.2

환자의 호흡에 의해 발생되는 인공물의 감소를 위한 다양한 방법들 중 호흡동조 시스템(이하 Q static scan)과 비교하여 CTAC Shift 보정방법, Additional scan(추가 검사방법)을 평가해보고자 한다. 본 연구는 2015년 2월에서 5월까지 본원을 내원한 환자들 중 영상에서 호흡에 의해 인공물이 발생한 환자 10명을 대상으로 진행하였으며 장비는 PET-CT Discovery 710 (GE Healthcare, MI, USA)과 호흡동조 시스템인 Varian사의 RPM system을 사용하였다. 환자는 24시간동안의 운동금지, 12시간동안 커피와 담배 금지, 8시간동안 금식을 한 후 충분한 수분을 섭취하고 도착시 혈관확보를 한 후 혈당 체크를 진행하며 $^{18}F$-FDG를 kg당 5.18 Mbq을 주사하였다. 그 후 1시간동안 안정을 취하고, 배뇨 후 검사를 진행하였다. CT조건은 관전압 120 kVp와 관전류 60 mAs, DFOV는 70 cm, Matrix size는 $192{\times}192$으로 모두 동일하게 진행하였다. 인공물이 발생한 영상을 기준으로 Additional scan, 호흡동조 시스템을 연동한 Q static scan, CTAC Shift 보정방법을 통해 영상화하였다. 각각의 영상에서 인공물의 감소를 비교하였으며, 육안적 평가와 SUVmax의 변화를 측정하였다. 인공물이 발생한 Whole body scan(WBS)을 통해 얻은 영상 대비 CTAC Shift 보정방법을 통해 얻은 영상의 경우 12~56%, Q static scan 영상은 17~54%, Additional scan 영상은 -27~46%의 변화율을 보였다. Blind Test에서는 CTAC Shift 보정영상이 4점으로 가장 높은 점수를 얻었고 Q static scan 영상이 3.5점, Additional scan 영상이 3.4점의 점수를 얻었다. Oneway ANOVA 검정을 통해 기준이 된 WBS scan 영상과 세 가지 Scan방법간에 유의한 차이를 보였으며(p<0.05) 세 가지 Scan방법간에는 유의한 차이를 보이지 않았다(p>0.05). 그러나 Blind test에서는 세 가지 Scan방법간의 유의한 차이를 보였다. Additional scan과 Q static scan은 CTAC Shift 보정 방법보다 시간이 소요되며 환자에게 CT 재촬영에 의한 과피폭이 우려되며 Q static scan은 호흡의 기복이 심하거나 통증으로 인해 호흡 주기가 불규칙한 환자의 경우 적용하기에 어려움이 있다. CTAC Shift 보정 방법의 경우 제한적으로 보정이 가능하며 그 범위 또한 제한적이다. 이를 보완하기 위해 각 병원의 시스템을 적절히 이용하고 각 방법의 장점의 여러 요소들을 발전시킨다면 진단적 가치를 높이기 위한 방법의 하나로써 유용할 것으로 사료된다. Purpose Among various causes that influence image quality degradation, various methods for decrease in Artifact occurred by respiration of patients are being used. Among them, this study intended to evaluate CTAC Shift correction method and additional scan compare to the Scan(Q static scan) using respiratory gated system. Materials and Methods This study was conducted on 10 patients, and used PET-CT Discovery 710 (GE Healthcare, MI, USA) and Varian's RPM system. 5.18 Mbq per kg of $^{18}F$-FDG was injected on patients, asked them to take a rest for 1 hour in the bed, and conducted test after urination. Images were visualized through Q static scan, CTAC Shift correction method, Additional scan based on the Whole body scan(WBS) with Artifact. Decrease in Artifact was compared in each image, conducted Gross Evalution, and measured changes of SUVmax. Results For image obtained through the CTAC Shift correction method through WBS with Artifact, 12~56%, Q static scan image showed 17~54% of change rate and Additional Scan showed -27~46% of change rate. In Blind Test, the CTAC Shift correction image showed the highest point with 4 points, Q static scan image showed 3.5 points, and Additional scan image showed 3.4 points. The standardized WBS scan through Oneway ANOVA and three types of Scan method showed significant difference(p<0.05), and did not show significant difference between the three Scan methods(p>0.05). However, the three Scan methods showed significant difference in Blind test. Conclusion Additional scan and Q static scan require more time than the CTAC Shift correction method, there is concern about excessive exposure to patients by CT rescan and Q static scan is difficult to apply on patients with inconsistent respiration or irregular respiration cycle due to pain. For CTAC Shift correction method, limited correction is possible and the range is limited as well. It is considered as a useful method of improving diagnostic value when hospitals use the system appropriately and develop various advantageous factors of each method.

In the present investigation, it is attempted to derive a yield function and associated flow rules of loose metal powders to predict plastic deformation and density change during compaction. The loose metal powders yield by shear stress as well as hydrostatic stress and the yield strength is much smaller in tension than compression. Therefore, a yield function for the powders is expressed as a shifted ellipse toward the negative direction in the hydrostatic stress axis in the space defined by the two stresses. Each of parameters A, B and .delta. used in the yield function is expressed as a function of relative density and it is determined by uniaxial strain and hydrostatic compressions using Cu powder. Flow rules obtained by imposing the normality rule to the yield function are applied to the analyses of unidirectional, bidirectional and hydrostatic compressions, resulting in an excellent agreement with experiments. The yield function is further examined by checking volume changes in plane stain, uniaxial strain and shear deformations.

본 연구는 여름 같은 고온기나 외부온도가 높지 않아도 시설내 온도가 많이 상승하는 봄 .가을 같은 시기에 온실내 고온 공기를 외부로 신속하게 유출시켜 강제환기를 사용하지 않고도 온실내부의 환경을 조절 할 수 있는 새로운 자연 환기창을 개발하는데 목적을 두고 수행하였다 패널굴절방식 측창은 지면에 가까운 쪽의 패널 하부에 절점을 두고 패널 상부가 측고 부위로부터 가이드 레일을 따라 하향하도록 구성하여 창이 개방되게 하였고, 천창은 측고 부위에 절점을 두고 용마루 쪽의 패널 상부가 가이드 레일을 따라 경사진 지붕면을 따라 하향하도록 구성하여 고온 공기층이 정체되어 있는 온실 상부인 측고 부위와 용마루 부위가 개방되도록 하였다. 굴절 패널의 상부 개방거리는 X=L(1-cos$\theta$)로 나타낼 수 있고 측면 개방 거리는 Y=L/2$\times$sin$\theta$로 나타낼 수 있다. 천창 개방시간은 4분 20초 소요되었으며 개방 시작한 2분 후부터 온도가 하강하기 시작하였고, 완전 개방 2분 후부터는 외기온과의 온도차 3~4$^{\circ}C$정도를 유지하면서 평형상태를 유지하였다. 패널굴절방식 환기창 온실의 환기성능은 체적환기량이 22.3-94.3m$^3$.m$^{-2}$ .h$^{-1}$이었으며, 환기 횟수는 15.2~39.3회.h$^{-1}$로 나타나 일반적인 연속형 천창의 10~15회.h$^{-1}$ 정도에 비해 환기효과가 높은 것으로 나타났다. 그리고 벤로형 온실과의 천창개폐시 온도하강을 비교하였을 때 환기효과가 2배 이상 높은 것으로 판단되었다.$_{r}$", $\mu$$_{r}$′) and the dielectric loss ($\varepsilon$$_{r}$"/$\varepsilon$$_{r}$′) were increased. It was caused that the absorption characteristics of the absorber were improved. The conduction loss and magnetic loss were expected to be occurred together because two matching frequencies were shown with carbon addition. It was confirmed that the matching frequency of the microwave absorber could be controlled by controlling heat-treatment temperatures and carbon additions.ons.tions.加的)으로 되거나 과가황(過加黃)이 될 우려가 있는 제조공정(製造工程)에서는 흔히들 이 방법(方法)을 무시(無視)하고 있다. 여기서 강조(强調)해 두어야 할 것은 항상 제품(製品)의 외부(外部)를 완전(完全)히 가황(加黃)시킬 필요(必要)는 없다는 것이다. 다공성(多孔性)이나 기포생성(氣泡生成)을 조장(助長)하는 불량가황상태(不良加黃狀態)와 표면(表面)에서의 과가황상태간(過加黃狀態間)의 균형(均衡)을 취(取)해 줘야 하는데 물론(勿論) 이때는 가황시간(加黃時間)을 단축(短縮)시켜야 한다는 경제적(經濟的)인 측면(側面)도 아울러 고려(考慮)해야 한다 In this study, new development of natural ventilation window was accomplished to control environment of greenhouse with no use of farced ventilation during hot season. The ventilation effect of developed ventilation window was investigated in experimental greenhouse which was designed using side wall panel and folding type panel fur natural ventilation. Folding panel type ventilation window was designed to open upper part of the side wall and top of the roof using two hinges which are located bottom of the side wall and the roof panel to grab one side of each panels and guide the other side along with the guidance rail. Developed ventilation window has top ventilation part with maximum moving distance X=ι (1-cos$\theta$)=848.5 mm and side ventilation part with maximum moving distance Y=ι/2 $\times$sin$\theta$=1,184.4 mm at 45$^{\circ}$ of theoretical opening angle. It took 4.5 minutes to open roof vent fully and temperature at 1.2 and 0.8 m height decreased after 1 minute from starting opening and became equilibrium state maintaining 3-4$^{\circ}C$ difference after 2 minutes from complete opening. Air exchange rate was 15.2~39.3 h$^{-1}$ which was more than 10~15 h$^{-1}$ of continuous type and Venlo type greenhouse. The descent effect of temperature by ventilation windows was two times higher than Venlo type greenhouse.
