Acoustic propagation in shallow water with changing environments is a major concern of navy. Temporal and spatial variability of acoustic propagation in the northern East China Sea (ECS) is studied, using the 11 years hydrographic data and the Bellhop acoustic model. Acoustic propagation in the northern ECS is highly variable due to extensive interaction of various ocean currents and boundaries. Seasonal variations of transmission loss (TL) with various source depths are highly affected by sharp gradient of sound speed and bottoms interaction. Especially, various bottom sediment types lead to severely degrading a waterborne propagation with bottom loss. In particular, the highly increased TL near the ocean front depends on the source position, and the direction of sound propagation.

Objective : The purpose of this study is to report and observe effects of Traditional Korean Medicine (TKM) on stage IV metastatic breast cancer patient. Method : A right breast cancer patient diagnosed with metastatic lesions on liver, lung, spleen, multiple bones and skin on right breast April 2013. The patient received Herceptin + Docetaxel + Zometa from May 2013 and started to receive TKM since July 2013 to decrease side effects of chemotherapy. From December 2013 to November 2014, she had received Herceptin 18 times more. The clinical outcomes were measured by computed tomography, laboratory findings including tumor markers (CEA, CA15-3), liver function test (AST, ALT), and numeric rating scales (NRS). Results : After 6 years of TKM treatment combined with standard chemotherapy, tumor size was partially decreased in lung, liver, right pleura and spleen. Levels of tumor markers also showed decrease. There were no severe adverse events induced by TKM based on National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE) version 4.0. Conclusion : This case suggests that TKM combined with standard chemotherapy could be a promising method for treating metastatic stage IV breast cancer.

파운드 오브제(Found object)를 융복합한 작품연구: 매체의 활용방식을 중심으로

박경주,Park, Kyungjoo 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.4

20세기 이후 산업화한 소비사회에서 생산된 기성품들은 '파운드 오브제 (Found object)'라는 새로운 소재로 미술작가들에게 채택되어 작품 속에서 넓은 의미로 재해석 되고 있다. 이를 활용해서 새로운 의미를 부여하는 방법은 표현양식뿐만 아니라 개념적으로도 확장된 새로운 패러다임을 생성한다. 현대미술에서 최초로 파운드 오브제가 사용된 1912년 파블로 피카소(Pablo Picasso)의 <Still Life with Chair Caning>이후 다다이즘과 초현실주의, 그리고 팝아트를 통해서 파운드 오브제의 전개를 파악하고 20세기 후반 파운드 오브제의 표현에 대해서 알아본다. 본 연구에서는 파운드 오브제가 작품에서 혼합된 방식에 따라서 '가공되지 않은 오브제', '변용된 오브제', 그리고 '차용된 오브제', 등 3가지 유형으로 구분하여 작가와 작품을 분석한다. 본 연구를 통해서 파운드 오브제를 융복합한 작품은 대상을 물질적으로 발전시킬 뿐만 아니라 미술의 전통적 규범에서 벗어나 자유로운 개념의 미술을 실천할 수 있도록 한다는 점에 주목한다. Ready-made products produced in the industrialized consumer society after the 20th century have been adopted by artists as a new material called "Found object," and are reinterpreted in a broad sense in their works. The method of giving new meaning using this creates a new paradigm that is expanded conceptually as well as expression style. After Pablo Picasso's <Still Life with Chair Caning> in 1912, when the Found object was used for the first time in contemporary art, we examine the development of objects through Dadaism, Surrealism, and Pop Art, and the expression of Found objects in the late 20th century. In this study, the artists and their work are analyzed by dividing it into three types: 'Unprocessed objects', 'Transformed objects', and 'Tenant objects', depending on how the Found object is mixed in works. Through this study, I pay attention to the fact that a work incorporating a Found object not only develops the object materially, but also allows the practice of free concept art to escape from the traditional norms of art.

예냉기와 예냉박스를 이용한 블루베리 저장성능에 관한 실험적 연구

박경주(Kyeong Joo Park) 산업기술교육훈련학회 2017 산업기술연구논문지 (JITR) Vol.22 No.4

Blueberries are harvested and distributed in summer. Summer fruits are harvested and circulated at high temperatures, which increases the respiration rate of the fruit, causing retraction and overripeness. This problem is directly linked to fruit quality and price declines. Proper cooling after harvest will affect shelf life and transportability of fruits and help to improve farmers’ profitability. We conducted an experimental study on the storage performance of blueberries using a differential pressure precooler and a precooling box for the cooling of blueberries after harvesting. With this precooler and precooling boxes, we were able to lower the temperature inside the fruit sufficiently in 2 to 4 hours whereas the forced air blowing takes 12~24 hours. This means the differential pressure precooler is more helpful for summer fruit in rapid packaging and delivery.

만성폐쇄성폐질환에서 흉부 CT의 임상적 이용

박경주 ( Kyung Joo Park ) 대한내과학회 2009 대한내과학회지 Vol.77 No.4

COPD는 흔히 폐공기증과 만성 기관지염이 혼합되어 나타난다. 폐기종은 병리적으로 정의되는 질환으로서 CT를 사용하여 정확한 진단이 가능하다. 또한 폐기종의 종류, 범위와 분포 등의 특성을 파악하는 데도 유용하다. CT를 이용하여 폐실질의 음영도 측정을 시행하면 객관적인 폐기종의 정량화가 가능하며, 중증의 폐기종에 대한 다양한 치료방법을 적용하기 위한 환자의 선택이나 치료결과를 추적하기 위한 정보를 얻을 수 있다. 검사결과의 의미 있는 비교를 위해서는 추적 CT를 시행할 때 항상 같은 영상 파라미터를 사용해야 한다. 만성기관지염은 임상증상으로 진단되며 CT 소견은 비특이적이다. CT를 사용하여 기도벽 비후를 객관적으로 측정할 수 있고, 이를 통해 COPD 환자에서 병태생리의 더 깊은 이해가 가능하리라고 기대된다. Chronic obstructive pulmonary disease (COPD) is commonly a combination of pulmonary emphysema and chronic bronchitis. Emphysema is a pathologically defined disease that can be accurately diagnosed using CT. Furthermore, CT is useful for determination of the subtypes, extent and distribution of emphysema. Objective quantification of emphysema is feasible using CT densitometry of lung parenchyma, that can be used for selection of adequate candidates and monitoring clinical results of various therapeutic measures for severe emphysema. Imaging parameters in CT densitometry should be kept constant in follow up examination for an effective comparison of the results. Chronic bronchitis is diagnosed by symptomatic criteria with nonspecific CT findings. Airway dimensions can be objectively measured using CT, enabling further understanding of pathophysiology of COPD. (Korean J Med 77:407-414, 2009)

This thesis pointed on < Banjohwajenga(반조화전가) > < Gisuga(기수가) > two gasa series, and looked into the aspects of ridicule and laughter and an end of dispute. On the ground of the result we demonstrated the esthetic characteristics of two gasa series according to concept of humor and satire. Two gasa series created against the disputant circumstances between men group and women group(< Banjohwajenga >) or within women groups(< Gisuga >), and attack to partner group expressed on works as a ridiculous speech take with laughter. But come to an end of dispute make peace with each other by reconcile within disputant groups or reconcile of outside disputant groups. We can confirm on works that the base of reconcile already planed in consciousness of disputant groups. Also < Banjohwajenga > series created between men group and women group are stronger than < Gisuga > series created within women groups from a strength of dispute. On the ground of this result the esthetic characteristics of two gasa series can conceptualized the variation of humor and satire. The disputant group recovered their pride and secured the unity with partner group by variation of humor and satire. And We can guess that this disputant groups recognized the disputant process as a play.

연구개발비가 기업경영 성과에 미치는 영향에 관한 연구

박경주(Park kyung-Joo),양동우(Yang Dong-Woo) 한국기술혁신학회 2006 기술혁신학회지 Vol.9 No.4

본 연구는 상장기업 311개 업체를 표본으로 하여 독립변수인 상장 이전 연구개발비에 대해 종속 변수인 상장 이후 기업 성과에 미치는 영향을 회귀분석을 통하여 실증 분석하였다. 연구결과는 다음과 같다. 첫째, IPO 직전년도 연구개발비는 IPO 당해년도 기업 성과인 평균 시가총액/자산은 모든 모형에서 유의한 양(+)의 상관관계를 미치고 있고, 평균 주가에는 모든 모형에서 유의한 결과를 보이지 않았으나 양(+)의 결과를 보였다. 또한 연구개발비 지출에 대한 매출액과 주당 순 자산의 변화는 통계적으로 유의 하지 않는 것으로 나타났다. 둘째, IPO 이전 3년 평균 연구개발비에 대한 IPO 당해포함 이후 3년 평균 기업성과는 평균시가 총액/자산에는 모든 모형에서 유의한 양(+)의 결과를 보였다. 평균 주가에 자산화 된 연구개발비에 따른 평균 주가 변동은 유의한 양(+)의 결과를 보였고 비용 화된 연구개발비의 경우는 유의한 음(- )의 영향을 미치고 있다. 이러한 결과는 기업들의 연구개발비에 따른 신호효과(singnal effect)로 인한 주가에 미치는 영향은 단기 혹은 중장기(3-5년)에 긍정적으로 나타나는 것으로 추정되나 원초적으로 기술 수준이 낮은 벤처 및 일반기업 등은 연구개발비가 기업성과에 단기적으로 수익성 제고에 부정적인 영향을 미치는 것으로 해석된다. This paper deals with an empirical study to statistically analyse various financial performances of the selected IPO firms using their investments on research and development(R&D) as an independent variables. The major results of statistical analyses have come up with the followings: 1) The regression analyses for change in average annual total market stock value/total assets over that of R&D expenditures showed the positive relationship. However, those of sales volume and net assets per share showed negative without statistical significances. 2) The statistical analyses in effect of the 3-year average total market stock value/total assets over the 3-year average R&D expenditures resulted in the positive coefficients what are statistically significant at 95% level. 3) Another statistical analysis showed that the financial performances of the IPO films with deferred assets were better than those of the firms without them. In sum, the degree of investment on R&D by the IPO firms are expected to positively affect their financial performances except the Finns without having proper original technologies.

규방가사가 지닌 소통과 화합의 문학으로서의 특성 고찰

박경주(Park, Kyeong-ju) 한국어문학회 2013 語文學 Vol.0 No.119

To date, studies on Gyubang Gasa (women’s traditional Korean poems) have been conducted from a feminism viewpoint. Recently, studies on Gyubang Gasa have been conducted from different viewpoints, drawing attention. These indicate that the existing feministic discussions helped understand Gyubang Gasa, and yet argue that a more developed discussion is needed to widen the understanding of Gyubang Gasa. These, although not all conducted in the same context, are considered agreeing that Gyubang Gasa is not a genre that was created and enjoyed only by women. This paper also examines Gyubang Gasa from this perspective. Gyubang Gasa as a genre of communication and unity is examined herein. A tradition was able to be confirmed by which conflicts were addressed through the creation and enjoyment of Gybang Gasa, and by which mutual communication and unity were pursued. To this end, the scope of Gyubang Gasa was more widely defined, and Gyubang Gasa was classified into women’s works and men’s works, and thus their communication patterns were examined. First, the scope of Gyubang Gasa was widely set according to its authors, its enjoyers, and its themes, and its communication and unity patterns were examined in diverse dimensions. As a result, in women-authored Gyubang Gasa, it was confirmed how women communicated with the world and how they interacted and were united with one another. In men-authored Gyubang Gasa, it was confirmed that men and women in th nobility interacted and were united with each other, that women and men indirectly interacted with each other, and thus that women communicated with the world. Gyubang Gasa’s main enjoyers, women of the nobility in the 18th-19th centuries, looked at the world and nurtured their appreciative minds to look at the world, through Gyubang Gasa. Also, they presented their thoughts to the world. They were able to foster the method of presenting their opinions and their ability of discussion through Gyubang Gasa.
