Ha Yoo-sang’s drama in 1950’s is well know that they displayed the generational conflict, but Jeolmeun sedaeui baekseo is unlike other works. Ha yoo-sang said that Jeolmeun sedaeui baekseo is human problem related to ‘the illusion’, so it should be is read in other way, not the generational conflict. After Korean war, South Korea is influenced by the Capitalism and the American Culture; English, translations, western clothes, dances and so on. These influences can be checked in Jeolmeun sedaeui baekseo with western style house and Christmas day. These western life styles are understand as the symbol of freedom. On the other hand, characters are affected by negative aspects of the capitalism, so they fell into values of mammonism. These elements are a kind of the influence of the Capitalism and the American culture at that time. Ha Yoo-sang showed negative aspects of the capitalism by defeating the negative characters, Yungisa and Hyeonsu, but Gyeonghui get parents’ permission to get married in spite of a negative character. Moveover, Ha Yoo-sang used English words in Jeolmeun sedaeui baekseo. Ha Yoo-sang knew changes and influences by the Capitalism and the American culture in late 1950’s, so he displayed these social phenomena. However he fell into the ambivalence of the Capitalism and the American culture because he had a popular tendency.

1950년대 이용찬의 작가 의식과 형식 실험 연구

이승현(Lee, Seung-hyun) 한국어문학회 2013 語文學 Vol.0 No.121

Lee Young-chan is well known by his drama Gajok(the Family). He focused on a family and it’s difficulties. He believed that family’s difficulties could are solved by family’s affection. However, his idea of family has a huge problem. It is that his concept of family is based on the patriarchy and the anti-communism. Due to the patriarchy, women who have become others appear from his dramas, so Lee Young-chan’s idea of family can not be completed perfectly. Futhermore, his idea of family is linked with idea of nation and people. Lee Young-chan said that people work for nation not only their families. This his idea is involved in the anti-communism. In the 1950s, the anti-communism is ideology of nation in Korean. At that time, the president Lee Seung-man used the anti-communism to catch state authority. Consequently, Lee Young-chan did not have the different author consciousness from old generation authors. Therefore, his formal experiments from Gajok, Giro, and Pineun Bamedo Jaji Anneunda have limited value. His formal experiments can not express the new generation consciousness, but they can be utilized to overcome the limits of Realism’s time and space.

Objectives : This study was conducted to evaluate the efficacy of a complex mixture of natural substances of ginseng and baeknyeoncho on the arthritic rats. Methods : In vitro experiments were conducted to ensure the stability of the complex. After setting toxicity and concentration by MTT assay, the antioxidant effect was measured through DPPH and ABTS radical scavenging activity. To confirm the anti-inflammatory effects of the complex, levels of nitric oxide (NO) and pro-inflammatory cytokines (IL-1β, TNF-α) were measured in LPS-treated macrophage cell lines (RAW264.7). We injected monosodium iodoacetate (MIA) 50 μl (60 mg/ml) into knee joints of rats to induce osteoarthritis. The rats were divided into three groups (normal (n=5), control (n=5), and OR (n=5) group). The control group consumed 2 mg/kg of physiological saline once a day for 4 weeks, and the OR group was mixed at a concentration of 416.5 mg/kg of Baengnyeoncho (O) and 208.25 mg/kg of red ginseng (R) and ingested 1 mL each 5 days a week. Results : This complex increased the DPPH and ABTS radical scavenging rate. The complex decreased NO production and pro-inflammatory cytokine production of macrophages. In the OR group, the secretion of cytokine in serum was decreased. In histopathological examination, the joint tissue of the composite showed less damage to the synovial membrane, cartilage, and fibrous tissue than the control group. Conclusions : As a result of this study, natural complexes have antioxidant, anti-inflammatory and cartilage protection effects. Therefore, we expect the complex to be effective in treating osteoarthritis.

이승현,박민순,Lee, Seung-Hyun,Park, Min-Sun Korea Computer Institute Society 2005 컴퓨터産業敎育學會論文誌 Vol.6 No.5

In this paper, we propose an efficient coding method of digital hologram using standard compression tools for video images. At first, we convert fringe patterns into video data using a principle of CGH(Computer Generated Hologram), and then encode it. In this research, we propose a compression algorithm is made up of various method such as pre-processing for transform, local segmentation with global information of object image, frequency transform for coding, scanning to make fringe to video stream, classification of coefficients, and hybrid video coding. The proposed algorithm illustrated that it have better properties for reconstruction and compression rate than the previous methods. 본 논문에서는 디지털 홀로그램의 효과적인 코팅 방법으로써 비디오 영상에서 사용되는 표준 압축 방식을 사용하였다. 먼저, 컴퓨터 형성 홀로그램(CGH)으로부터 생성된 격자패턴을 비디오 데이터로 변환한 다음 이를 부호화 하였다. 또한, 변환을 위한 전처리, 물체 영상의 전체적인 정보에 대한 국부적인 영역분할, 부호화를 위한 주파수 변환, 격자패턴의 비디오 스트림을 위한 스캐닝, 계수 값의 분류, 복합적인 비디오 부호화 등을 제안하였다. 제안된 복합 압축 알고리듬은 기존의 방법에 비해 뛰어난 압축율과 재생력을 얻을 수 있었다.

양성자 치료 시 방사선 작업 종사자에게 미치는 방사선 피폭에 대한 평가

이승현,장요종,김태윤,정도형,최계숙,Lee, Seung-Hyun,Jang, Yo-Jong,Kim, Tae-Yoon,Jeong, Do-Hyung,Choi, Gye-Suk 대한방사선치료학회 2012 대한방사선치료학회지 Vol.24 No.2

목 적: 기존의 광자선을 이용한 선형가속기와는 달리, 양성자 치료의 경우 물질과의 상호작용으로 발생되는 중성자를 비롯한 여러 핵종 등으로 인해 다량의 이차방사선이 생성되기 때문에 방사선 작업 종사자의 피폭은 더욱 주의 깊은 관심이 필요하다. 이에 방사선 측정 시에 널리 이용되고 있는 열형광선량계를 이용하여 방사선 작업 종사자의 피폭정도를 평가하고 이를 토대로 양성자 치료 시 방사선 피폭선량에 관한 기초 자료를 제시하고자 한다. 대상 및 방법: 본원의 양성자 치료실에서 근무한 방사선 작업 종사자를 대상으로 열형광선량계 뱃지를 이용해 피폭현황을 측정한 데이터를 비교했다. 양성자의 빔 라인 주변에서 발생하는 이차방사선의 신체부위별 피폭선량 분포를 알아보고자 신체부위(외안각, 목, 유두점, 배꼽, 등, 손목)에 가로, 세로가 각각 3 mm인 정사각형 모양의 열형광선량계를 부착하여 일일 8시간의 근무시간동안 유지하도록 하였고 총 80시간 측정하여 평균 데이터를 얻었다. 그리고 치료실 내 공간적인 방사선량의 분포를 보기 위하여 빔 사출구, PPS (Patient Positioning System), Pendant, 차폐체보관장, DIPS (Digital Image Positioning System) Console, 출입통로에 각각 열형광선랑계를 부착하고 일일 근무시간 동안의 평균 방사선량을 측정하였다. 결 과: 방사선 작업 종사자의 열형광선량계 뱃지로 측정된 피폭량을 조사한 결과 분기별 평균 0.174 mSv, 연평균 0.543 mSv로 나타났고 신체부위별로 측정한 결과에서 가장 많은 피폭량을 보인 곳은 목이였으며 가장 적은 피폭량을 보인 곳은 등(양견갑골 상각을 이은 선의 중간 지점)으로 나타났다. 작업 동선에 따른 공간적 방사선량을 알아본 결과에서는 빔 사출구 근처에서 상대적으로 높게 나타났고 거리가 멀어짐에 따라 줄어들었다. 결 론: 적은 양의 피폭일지라도 동일 장소에서 장기 근무하게 되면 피폭 누적량은 증가할 수밖에 없고 특정 부위의 누적량은 건강상의 위험을 가져다 줄 수도 있다. 그러므로 국제 방사선 방어 위원회가 권고하는 ALARA의 원칙에 따라 가능한 합리적으로 감소시킬 수 있도록 스스로 개인별 피폭관리에 철저를 기하고 피폭을 최소화시키는데 최선의 노력을 다해야 할 것이다. Purpose: Unlike the existing linear accelerator with photon, proton therapy produces a number of second radiation due to the kinds of nuclide including neutron that is produced from the interaction with matter, and more attention must be paid on the exposure level of radiation workers for this reason. Therefore, thermoluminescence dosimeter (TLD) that is being widely used to measure radiation was utilized to analyze the exposure level of the radiation workers and propose a basic data about the radiation exposure level during the proton therapy. Materials and Methods: The subjects were radiation workers who worked at the proton therapy center of National Cancer Center and TLD Badge was used to compare the measured data of exposure level. In order to check the dispersion of exposure dose on body parts from the second radiation coming out surrounding the beam line of proton, TLD (width and length: 3 mm each) was attached to on the body spots (lateral canthi, neck, nipples, umbilicus, back, wrists) and retained them for 8 working hours, and the average data was obtained after measuring them for 80 hours. Moreover, in order to look into the dispersion of spatial exposure in the treatment room, TLD was attached on the snout, PPS (Patient Positioning System), Pendant, block closet, DIPS (Digital Image Positioning System), Console, doors and measured its exposure dose level during the working hours per day. Results: As a result of measuring exposure level of TLD Badge of radiation workers, quarterly average was 0.174 mSv, yearly average was 0.543 mSv, and after measuring the exposure level of body spots, it showed that the highest exposed body spot was neck and the lowest exposed body spot was back (the middle point of a line connecting both scapula superior angles). Investigation into the spatial exposure according to the workers' movement revealed that the exposure level was highest near the snout and as the distance becomes distant, it went lower. Conclusion: Even a small amount of exposure will eventually increase cumulative dose and exposure dose on a specific body part can bring health risks if one works in a same location for a long period. Therefore, radiation workers must thoroughly manage exposure dose and try their best to minimize it according to ALARA (As Low As Reasonably Achievable) as the International Commission on Radiological Protection (ICRP) recommends.

이승현,장인성,Lee. Seung Hyun,Jang. In Sung 한국방재학회 2013 한국방재학회논문집 Vol.13 No.6

진동타입기에 의해 시공되는 말뚝의 해석을 위한 해석기법을 개발하고 해석기법의 신뢰성을 평가해보기 위해 시스템변수를 달리하여 해석을 수행하였다. 말뚝의 동적 주면마찰 하중전이곡선을 결정짓는 부주면마찰력의 크기는 정적 연직하중이 작용하지 않는 경우에 대한 해석을 통해 시행착오적으로 구할 수 있을 것으로 생각된다. 진동타입기에 의해 시공되는 말뚝의 연직변위량은 정적 연직하중의 크기에 비례하는 결과를 보였다. 진동타입시 말뚝의 가속도는 부주면 마찰력 및 정적 연직하중과는 무관하며 기진력의 크기에 의존함을 알 수 있었다. 정적 연직하중의 증가에 따른 말뚝주면 하중전이곡선의 변화양상을 비교해 볼 때 진폭은 거의 일정하나 곡선이 전체적으로 상향으로 이동함을 알 수 있었다. 말뚝선단 하중전이곡선에 대하여 최대 하중값은 부주면 마찰력 및 정적 연직하중의 크기와 무관하게 일정함을 알 수 있었다. Technique for analyzing a pile installed by vibratory pile driver was developed and analyses were performed with varying system variables in order to evaluate reliability of the developed technique. Negative skin friction which defines dynamic skin load transfer curve seems to be obtained by trial and error method for the situation without static vertical load. Vertical displacment of the pile was proportional to the static vertical load. It can be seen acceleration of the pile was dependent on excitation force regardless of the negative skin friction and the static vertical load. Comparing the shapes of skin load transfer curves with static vertical load, amplitudes of the curves were nearly the same but it can be seen that the curves shift to upward. Maximum values of the toe load transfer curves were constant regardless of the negative skin friction and the static vertical load.

As the theme of a theme park space with limited space emerged as a keyword, many experiments and research were conducted in the field. In the domestic market, not only the creation of new spaces, but also the need to develop marginalized spaces and seek complementary points through new interpretations of actual spaces, but they show physical limitations. This study newly redefined and analyzed the concept of space by approaching and interpreting virtual space as a new space. By exploring real-world examples and analyzing the results, we also derive the results that the possibility of realistic media in the virtual world is an exemplary alternative to complementing the expansion and limitations of the space. Realistic media has a wide range of content provision in selective development such as AR and VR, and the theme park's characteristic of providing various contents for quarterly concepts even if the development budget and time are small, which has a significant impact on the development of realistic media. Currently, theme parks are attracting countless majors and officials related to realistic media through metaverse. As it is attracting attention in such a new market, we look forward to seeing a lot of research and experiments in the project.

본 연구에서는 침몰선박 위해도 평가항목 및 평가지수를 개정하고 신규항목을 도출하기 위해 전문가를 대상으로 AHP 기법의 설문을 실시하였다. 설문조사 결과, 사고원인 및 조류영향 등 두개의 신규항목을 도출하였으며 하나의 그룹으로 평가되었던 독성액체물질과 연료유적재량, 폭발성가스는 각각 평가하는 것이 적합한 것으로 나타났다. 이에 따라 기존 일곱 개 평가항목을 열한 개 항목으로 조정하여 평가항목별 지수를 분석한 결과, 독성액체물질, 유출가능성, 폭발성가스, 연료유적재량, 해역환경민감도, 해상교통환경, 사고원인, 조류, 여유수심, 선박종류, 선박규모 순으로 평가지수가 나타났다. 특히, 신규 도출된 평가항목 지수를 기존 위해도 평가항목과 비교해 보았을 때 해역환경민감도와 유출가능성 항목은 기존 평가지수 보다 높게 나타났고, 여유수심 항목의 평가지수는 더 낮게 나타났다. In this study, we have conducted a survey of AHP technique through the ocean experts to derive new items and revise assessment items and indices for risk of sunken ships based on the survey results. As a result of the survey, two new items such as accident cause and tidal current are derived. And it shows that existing items such as toxic liquid substance, remaining oil and explosive gas which were evaluated as one group are desirable to be evaluated respectively. Accordingly, we analyze the indices of the new eleven assessment items adjusted from the existing seven assessment items. As a result, the indices are ordered by toxic liquid substance, possibility of leaking, explosive gas, carrying capacity of fuel oil, sensitivity of sea environment, marine traffic environment, cause of accident, tidal current, keel clearance, ship type, and ship size. Especially, as compared with the indices of existing assessment items, the indices of sensitivity of sea environment and possibility of leaking are higher and the index of keel clearance is lower.
