김전기,박송희,이상준 부산대학교 환경문제 연구소 1987 環境硏究報 Vol.5 No.-

부산시 수영만으로 유입되는 수영천과 온천천의 4개지점에서 1985년 5월부터 1986년 4월까지 매월 1회 채수한 시료로부터 분해세균을 분리동정하여 그 생태학적 특성에 관해 조사한 결과는 다음과 같다. 1. 수온은 평균 18.2±7.72℃ 이었으며, 그 범위는 4.5-30.0℃이었다. 월별 수온변화는 2월이 가장 낮고 8월이 가장 높았다. 2. pH는 평균 6.8±0.26 이었으며, 그 범위는 6.4-7.2이었다. 여름철은 약알카리성, 겨울철은 약산성을 나타내었다. 3. LAS 농도는 평균 4.8±2.11ppm 이었으며, 그 범위는 1-9 ppm이었다. 지점별로는 온천교 6.0±1.88ppm, 이섭교 5.9±2.30ppm, 원동교 4.0±1.33ppm, 수영교 3.5±1.51ppm의 순이었다. 4. LAS 분해균수의 변화는 LAS 농도보다는 오히려 계절적인 영향을 많이 받는것으로 나타났다. 5. 총균수에 대한 LAS 분해균의 점유율은 봄철이 0.4%로 가장 높았으며, 지점별로는 온천교 부근이 가장 높았고 수영교 부근이 가장 낮았다. 6. 분리된 LAS분해균주를 분류동정한 결과 총 15속으로 대부분 그람음성세균이었으며, Listeria속만이 그람양성세균으로 나타났다. 7. 전 지점에서 년평균 10% 이상의 출현빈도를 보인 LAS 분해세균은 Alcaligenes속, Klebsiella속, Pasteurella속이었다. 8. Pasteurella 속이 전지점에서 우점종으로 나타났으며, 온천교 부근과 이섭교 부근에서는 Klebsiella속, 원동교와 수영교 부근에서는 Alcaligenes 속이 준우점종으로 나타났다. Lenear alkylbenzene sulfonates(LAS) degrading bacteria were isolated from the Oncheon and the Sooyoung streams in Pusan area. Samples were monthly taken from the surface waters at four designated sites from May, 1985 to April, 1986. The isolates strains were identified and ecological studies on these identified strains were investigated. The results obtained were as follows: 1) Average water temperature was 18.2±7.72℃ with range of 4.5 to 30.0℃. Water temperature was the lowest in February and the highest in August. 2) The mean value of pH was 6.8±0.26 with range of 6.4 to 7.2. The pH value showed slight alkalinity in the summer and slight acidity in the winter. 3) The mean concentration of LAS was 4.8±2.11ppm with range of 1 to 9 ppm. The highest concentration of LAS was found in the water sample of the Oncheon bridge area(6.0±1.88ppm) followed by the Iseup bridge (5.9±2.30ppm), the Weondong bridge(4.0±1.33ppm), and the Sooyoung bridge area(3.5±1.51ppm). 4) Number of the LAS degrading bacteria was effected by the seasonal change rather than LAS concentration. 5) The ratio of the LAS degrading bacteria to the total cells was the highest as 0.4% in spring. The highest and lowest ratio was at the Oncheon and the Sooyoung bridge area respectively. 6) All isolated strains were characteristically Gram-negative bacteria except only Listeria genus. 7) The appearance frequency of Alcaligenes, Klebsiella, and Pasteurella was showed more than 10% at all sites. 8) The dominant strains of LAS degrading bacteria were genus Pasteurella at all sites. The subdominants were genus Klebsiella at the Oncheon and the Iseup bridge area, and genus Alcaligenes at the Weondong and the Sooyoung bridge area.

Comparison of Adult Brassier between Korea and Japan : Based on the Information on the Internet

Joen, Mi-Sun,Park, Myung-Ja,Lee, Kyu-Hye 복식문화학회 2004 Fashion, industry and education Vol.7 No.2

A brassier supports and protects breasts and makes a better shape of the upper half of the body through shaping breasts. A brassier, therefore, is recognized as the key underwear for female. Recently, the distribution structure and channels of the brassiere industry is diversified from conventional type of markets to department stores, convenience stores, and internet shopping mall. Studies on the sales of brassieres via internet, however, is not sufficient even though the market size has been dramatically increased thursdays. The study on the size structure (including the size and the materials fabric of brassieres circulating via internet) is especially rare. Therefore, this study tries to comply with increasing requests of consumers through comparing brassier brands on internet. In depth, this study compares cases of Korea and Japan in terms of availability of website on sales, quality indication like materials and functions, and size. The results indicated that there were three companies in Korea which run a website and make a sale through a website. All three Japanese companies operate a website and make sales on a website as well. In terms of size, Korean companies diversify their size of products in two ways. It varies from A cup to D cup based on cup size, and 65 to 100 according to its entire size. On the other hand, Japanese companies use AA, A to I to measure cup size, and 65 to 100 for entire size.

Diagnostic value of procalcitonin and CRP in critically ill patients admitted with suspected sepsis

Joen, Jae-Sik,Ji, Sung-Mi The Korean Dental Society of Anesthsiology 2015 Journal of Dental Anesthesia and Pain Medicine Vol.15 No.3

Background: Identifying early markers of septic complications can aid in the diagnosis and therapeutic management of hospitalized patients. In this study, the utility of procalcitonin (PCT) vs. C-reactive protein (CRP) as early markers of sepsis was compared. Methods: A series of 2,697 consecutive blood samples was collected from hospitalized patients and serum PCT and CRP levels were measured. Patients were categorized by PCT level as follows: < 0.05 ng/ml, 0.05-0.49 ng/ml, 0.5-1.99 ng/ml, 2-9.99 ng/ml, and > 10 ng/ml. Diagnostic utility was analyzed by receiver operating characteristic (ROC) curves. Results: Mean CRP levels varied among the five PCT categories at $0.31{\pm}2.87$, $5.65{\pm}6.26$, $13.78{\pm}8.01$, $12.15{\pm}10.16$, and $17.77{\pm}10.59$, respectively (P < 0.05). PCT and CRP differed between positive and negative blood culture groups (PCT: 15.9 vs. 4.78 mg/dl;CRP: 11.5 ng/ml vs. 9.57 ng/ml;P < 0.05). The areas under the ROC curves (PCT, 95% confidence interval [CI]: 0.743, range: 0.698-0.789 at a threshold of 0.5 ng/ml; CRP, 95% CI: 0.540, range: 0.478-0.602 at a threshold of 8 mg/l) differed for PCT and CRP (P < 0.05). Conclusions: Therefore, PCT is a reliable marker for sepsis diagnosis and is more relevant than CRP in patients with a positive blood culture. These findings can be useful for the treatment of critically ill sepsis patients.

김춘수 초기 시에서 나타난 존재론적 사유의 흔적

전세진(Joen, Se-Jin) 한국시학회 2018 한국시학연구 Vol.- No.55

본 논문은 김춘수의 초기 시에서 나타나는 존재론적 사유의 흔적을 발견하고 이를 통해 1950년대 김춘수가 꽃 피운 존재론적 시로 나아가기 이전 그가 가지고 있던 사유의 특징과 의미를 밝히는 것을 목표로 한다. 이를 위해 김춘수의 존재론적 시를 특정 사상과의 영향 관계 속에서 해명하려는 관점에서 나아가 김춘수 초기 시에서 형성되고 있던 시 세계를 조망함과 동시에 그가 어떻게 존재론적 사고를 구축해나갔는지를 단계적으로 살펴보고자 한다. 이에 따라 본고에서는 ‘릴케’ 혹은 ‘하이데거’와의 직접적인 영향 관계를 전제로 두고 김춘수의 시를 해석하려는 시도는 지양할 것이다. 이는 ‘존재론적 사유’라는 것이 특정한 사유의 계보 속에서 밝혀질 때에 가장 유효한관점을 마련해줄 것인가에 대한 의문이 남기 때문이다. 따라서 이러한 영향의 계보학적 탐색보다는 실제 김춘수에 시에서 나타나고 있는 본질적인 존재론적 양상을 고찰할 것이다. 김춘수는 언어와 존재 사이의 좁혀지지 않는 틈을 인식하는 데에서 오는 딜레마와 그럼에도 불구하고 그것을 극복해나가려는 시인으로서의 자각이 분명한 시인이었다. 이러한 자각은 한 순간에 발생한 것이 아니기에 오랜 시간에 걸쳐 의식적으로, 혹은 무의식적으로 남겨온 존재론적인 사유에 대한 흔적을 통해 확인할 수 있게 된다. 실제로 그의 첫 시집 『구름과 장미』(1948)를 시작으로 『부다페스트에서의 소녀의 죽음』(1959)에 이르기까지 10여 년의 시간 동안 그는 총 7권의 시집과 시선집을 내며 부단히 시를 썼고, 하나의 시집에서 다른 하나의 시집으로 넘어갈 때에 스스로가 물었던 질문들이 정리되고, 또 새로운 질문이 제기되며 사유의 폭이 넓어지고 있음을 확인할 수 있다. 이에 본고는 그 사유가 변화하는 과정을 따라가며 김춘수의 초기 시에서 존재론적 사유의 흐름을 발견한다. 즉 ‘바로 봄’을 통해 ‘존재 물음’이 시작되고, 이것이 ‘존재 의미’의 문제와 깊에 연관되며, 결국은 ‘관계 맺음’을 통해 ‘현존재’로서의 ‘본래적 자기’를 찾게 되는 일련의 흐름을 갖추고 있음을 알 수 있다. 이는 곧 어떠한 특정 계보 속에서 김춘수의 시를 해석하기보다 김춘수의 시 자체에 내재적으로 생성되고 있는 사유가 있었음을 확인할 수 있는 하나의 근거가 될 것이다. This study aims to rediscover the meaning of Kim, Chun-Soo"s early poems and to reveal the characteristics of his thoughts before Kim, Chun-Soo wrote ontological poetry in the 1950s as finding out the traces of ontological thoughts in Kim, Chun-Soo"s early poems. For this purpose, this study will go further in an attempt to clarify Kim Chun-su"s ontological poetry in relation to certain ideas, it will look at how Kim, Chun-Soo’s early poetry world was formed and at the same time, how he built his own ontological thought. In order to do so, this study will avoid to interpret Kim, Chun-Soo"s poetry as a direct influence relationship with "Rilke" or "Heidegger". This is because there is a question as to whether the "ontological thought" is revealed in the genealogy of a particular thought, and whether it will provide the most effective viewpoint to look into the thought of a poet. Therefore, rather than the genealogical exploration of these influences, I will examine the essential ontological aspects of Kim, Chun-Soo’s poetry. Kim, Chun-Soo was aware of the dilemma in recognizing the narrow gap between language and existence, and was aware of the need to overcome it. This awareness can be confirmed not only by a moment but by a trace of ontological thinking that has been consciously or unconsciously left over for a long time. In effect, for over a decade, from his first book of poems Clouds and Roses(1948) and to the death of a girl in Budapest (1959), he wrote a total of seven poem books, When he moved from one poem book to another book, it is able to see that the questions he has asked are sorted, new questions are raised, and the breadth of thought is expanding. As following the changing process of the thought, I find the flow of ontological thought in Kim, Chun-Soo"s early poems. It has a series of flows which is from ‘question of being’ through ‘look right’ to how it is deeply related to ‘meaning of being’ and it eventually finds "original self" as "Dasein" through "making relationship". Through this, rather than interpreting the poems of Kim, Chun-Soo in any particular genealogy, there was an intrinsic thought for Kim, Chun-Soo"s poetry itself, and this can be a basis for explaining Kim Chun-su"s characteristics of the poetic world.
