장수덕,송영화 한국중소기업학회 2003 中小企業硏究 Vol.25 No.1

본 연구의 목적은 IMF 경제위기를 전투한 벤체기업의 환경, 전략 및 조직특성의 변화와 성과변화간의 관계를 규명하는 것이다. 이를 위채 연구자들은 기존 연구를 토대로 연구모형과 가설을 개발했다. 그리고 가검증을 위해 IMF를 전후한 두 기간(1994년-7995년과 1997년-1999년)에 걸쳐 74개 벤처기업을 대상으로 종단적 자료를 수집했다. 수집된 자료를 토대로 연구자들은 벤처기업의 환경, 전략 및 조직특성의 변화와 성과변화 유형간의 관계를 다중 로지스틱 회귀분석을 통해 분석했다. 그 벨과 연구자들은 다음과 같은 연구결과를 얻을 수 있었다. 첫째, 벤처기업의 성과변화에는 원가 및 기술에 있어서 유리하게 전개된 환경적 변화가 중요한 영향을 미쳤다. 둘째, 벤처기업의 성과변화에는 원가우위, 마케팅차별화, 그리고 외부자원활용 전략의 변화가 중요한 영향을 미쳤다. 셋째, 벤처기업의 성과변화에는 조직특성에 있어서 계층화의 변화가 중요한 영향을 미쳤다. 이러한 연구결과를 토대로 연구자들은 본 연구가 가지는 몇 가지 이론적 및 실무적 시사점 도출할 수 있었다. This research purports to examine the relationship between changes in performance and changes concerning environmental, strategic and organizational aspects through a longitudinal study of Korean high-tech ventures before and after the IMF bailout programs. We developed a research model as well as a set of hypotheses by examining the previous studies. Longitudinal data were collected from 74 venture firms in two periods (1994-1996 and 1997-1999) to test the hypotheses. On the basis of collected data, we analysed how environmental, strategic and organizational factors are related to performance changes of ventures. The findings of this study are summarized as follows: 1) Performance changes of ventures were significantly related to favorable cost and technology transfer after the IMF-bailout program. 2) Performance changes of ventures were significantly related to strategies such as cost leadership, marketing differentiation, and external resource utilizing strategy. 3) Although the model 111 was low, it was shown that performance changes of ventures were related to organizational structure such as classification.

산림은 많은 양의 탄소를 저장하고 있으며, 산림 탄소 동태는 기후변화에 따라 변화할 것으로 예상된다. 본 연구는 우리나라 산림에서 가장 우점하는 침엽수종과 활엽수종인 소나무림과 참나무림을 대상으로 최근 개발 및 개선된 한국형산림토양탄소모델(Korean ForestSoil Carbon model; KFSC model)을 이용하여 두 가지 기후변화 시나리오(2012년 기온이 2100년까지 유지되는 시나리오(CT), Representative Concentration Pathway(RCP) 8.5 시나리오) 하에서의 산림 탄소 동태를 예측하였다. 5차 국가산림자원조사 자료로부터 소나무림과 굴참나무림 조사구들을 추출한 뒤, 이를 행정구역(9개 도, 7개 특별·광역시) 및 영급(1-5영급, 6영급이상)별로 분류하여 탄소 동태 모의 단위를 설정하였다. 탄소 저장고는 2012년을 기준으로 초기화하였으며, 모의 기간인 2012년부터 2100년까지 모든 교란은 고려하지 않았다. 모의 결과 산림 탄소 저장량은 시간이 경과함에 따라 전반적으로 증가하지만, CT 시나리오에 비하여 RCP 8.5 시나리오 하에서 산림 탄소 저장량이 낮게 나타났다. 소나무림의 탄소 저장량(Tg C)은 2012년에 260.4에서 2100년에는 각각 395.3(CT 시나리오) 및 384.1(RCP 8.5 시나리오)로 증가하였다. 굴 참나무림의 탄소 저장량(Tg C)은 2012년에 124.4에서 2100년에는 219.5(CT 시나리오) 및 204.7(RCP 8.5 시나리오)로 각각 증가하였다. 5차 국가산림자원조사 자료와 비교한 결과, 고사유기물 탄소 저장량의 초기값은 타당한 것으로 나타났다. 모의 기간 동안 소나무림과 굴참나무림의 연간 탄소 흡수율(g C m-2 yr-1)은 CT 시나리오 하에서 각각 71.1과 193.5, RCP8.5 시나리오 하에서 각각 65.8과 164.2로 추정된다. 따라서 우리나라 소나무림과 굴참나무림의 탄소 흡수잠재력은 지구 온난화에 의하여 감소할 것으로 예상된다. 비록 모델의 구조와 파라미터로부터 불확실성이 존재하지만 본 연구는 미래 산림 탄소 동태 파악에 기여할 것으로 기대된다. Forests contain a huge amount of carbon (C) and climate change could affect forest C dynamics. This study was conducted to predict the C dynamics of Pinus densiflora and Quercus variabilis forests, which are the most dominant needleleaf and broadleaf forests in Korea, using the Korean Forest Soil Carbon (KFSC) model under the two climate change scenarios (2012-2100; Constant Temperature (CT) scenario and Representative Concentration Pathway (RCP) 8.5 scenario). To construct simulation unit, the forest land areas for those two species in the 5th National Forest Inventory (NFI) data were sorted by administrative district and stand age class. The C pools were initialized at 2012, and any disturbance was not considered during the simulation period. Although the forest C stocks of two species generally increased over time, the forest C stocks under the RCP 8.5 scenario were less than those stocks under the CT scenario. The C stocks of P. densiflora forests increased from 260.4 Tg C in 2012 to 395.3 (CT scenario) or 384.1 Tg C (RCP 8.5 scenario) in 2100. For Q. variabilis forests, the C stocks increased from 124.4 Tg C in 2012 to 219.5 (CT scenario) or 204.7 (RCP 8.5 scenario) Tg C in 2100. Compared to 5th NFI data, the initial value of C stocks in dead organic matter C pools seemed valid. Accordingly, the annual C sequestration rates of the two species over the simulation period under the RCP 8.5 scenario (65.8 and 164.2 g C m-2 yr-1 for P. densiflora and Q. variabilis) were lower than those values under the CT scenario (71.1 and 193.5 g C m-2 yr-1 for P. densiflora and Q. variabilis). We concluded that the C sequestration potential of P. densiflora and Q. variabilis forests could be decreased by climate change. Although there were uncertainties from parameters and model structure, this study could contribute to elucidating the C dynamics of South Korean forests in future.

The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

Lung cancer has been the most commonly diagnosed type of cancer and the leading cause of cancer related mortality in Korea and worldwide. Although it is fatal, most of the lung cancer patient are asymptomatic at the time of diagnosis. Therefore, radiologic screening by chest low-dose computerized tomography (LDCT) has been recommended by lung cancer specialists for early detection and improving survival. However, clinical suspicion of lung cancer by radiologic screening is quite challenging because of its high false positive rate. A wide range of benign pulmonary diseases could be misinterpreted as lung malignancy on LDCT, including infection, benign mass-forming lesion, and inflammatory changes. Therefore, physician should consider the possibility of the benign disease entities when radiologic features suggest lung malignancy. Herein, we report a case of a 50-year-old man presenting a 4.5-cm lung mass in the right upper lobe with solitary osteolytic lesion of the right 8th rib. Under the suspicion of metastatic lung cancer, the lung mass and the right 8th rib were surgically resected for the diagnostic and curative purpose. After the tissue biopsy, unexpectedly, the lung mass was diagnosed as inflammatory pseudotumor. Furthermore, histopathology of the resected rib showed solitary plasmacytoma of the bone. Our experience highlights the importance of clinical suspicion that in patients with radiologic features compatible to advanced lung cancer could be caused by coexistence of unrelated two uncommon disease entities, which can be completely treatable with surgical resection.

Purpose: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. Methods: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Results: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. Conclusion: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

Chang, Kun Soo,Yeo, Yeong Koo,Chang, Jin Yang,Kim, Kil Su,Jeong, Eun Young,Oh, Sea Cheon 한국화학공학회 1997 Korean Journal of Chemical Engineering Vol.14 No.5

In the present study a reliable and structural decision system for production sequence of polymeric products is developed. Minimization of the amount of off-specs are the main objective in the decision of production sequence to maximize profit. Off-specs are generated when the production sequence of polymeric products is changed. The amount of off-specs depends on changes of product grades. In the present study we applied the traveling salesman problem (TSP) to achieve optimal decision of production sequence. To solve the optimal decision problem formulated by TSP, we employed three different approaches such as Branch and Bound (B&B) method. Dynamic Programming (DP) method and Hopfield Neural Network (HNN) method. Production sequences computed based on the actual plant off-spec data were compared with the sequences employed in the actual plant operation. From the comparison the decision method proposed in the present study showed increased profits and reduced off-specs.

Hair style is very important factor in determining esthetic expression, and its form has been changed as the society changed. A new, original and differentiated style is required to be abe to express the social phenomena. The personal character, social position, and attitude could be judged from the hair style. Thus, the hair style is strong tools for personal communication and image delivery as well as esthetic expression. First, the shape of the human face could be changed positively by altering the hair style. The weak point can be hidden, and the strong point can be looked better. Second, a study of hair style on face shape leads us find out personal images including strong and weak point. The personal characters can be reexpressed by using this scientific principle. Third, the image of hair style is not determined by one factor but determined by various factors. The hair style can be completed by combination of design type, color, texture according to each shape of face. We believe the deep and various study on hair style is needed to express the social culture, value, and ideology. The research for the new and original techniques are also requested to be able to make-up various shape of face.

염상섭 문학에 나타난 '죽음'

장두영(Chang Du-yeong) 한국현대문학회 2012 한국현대문학연구 Vol.0 No.37

본고는 다수의 염상섭 작품에서 죽음이라는 소재가 빈번히 다루어지는 현상에 주목하여 염상섭 소설에 나타난 죽음의 형상화와 죽음에 대한 인식을 살펴보았다. 1920년대 초반 염상섭의 작품에 나타나는 죽음은 부정적인 현실에서 초월하여 영원, 진·선·미 등 형이상학적 가치들로 표상되는 진정한 삶에 진입하는 구원의 방편으로 제시되며, 이것은 죽음을 신비적이고 낭만적인 기호로 취급하는 당대 문단의 담론과 이어진다. 염상섭의 작품에서 데카당스의 대표작이나 죽음에 깊은 관심을 표명한 러시아 작품이 산발적으로 언급되고 있는 것을 볼 때 작가의 죽음에 대한 인식은 일차적으로 서구문학의 독서체험과 연결됨을 알 수 있다. 그러나 구체적인 작품에서 나타나는 죽음의 형상은 서구의 것과는 일정한 차이를 보이고 있는데, 이것은 창작과정을 거치면서 작가 고유의 미학적 관념이 투영된 결과로 해석된다. 염상섭이 죽음과 창작에 대해 가졌던 생각은 '죽음의 예술화'로 정식화되는데, 죽음은 그 자체로는 일종의 자연현상에 속하지만 주관적 관념을 거치면서 미를 멱출할 수 있다는 것이다. 주관적 관념의 매개를 강조한 결과 1920년대 초반 발표된 염상섭의 작품에서는 죽음이 사건으로서의 의미보다는 인물의 내적 성찰을 이끌어내기 위한 계기로 설정되는 경향이 강하게 나타난다. 서사 전체가 죽음에 이르는 인물의 내적 고민과 방황의 과정을 드러내는 데 중점을 두는 작품의 특성상 죽음은 주로 작품의 결말 부분에 집중적으로 제시되고 현상으로 이어지게 된다. 한편 1930년대의 대표작에서 죽음이 형상화되는 방식을 살펴보면 이전 시기의 작품에서와는 뚜렷한 차이가 발견된다. 이상적인 구원이나 신비적인 형이상학적 가치와 연결되던 모습이 사라지고, 죽음에 이르는 인물의 내면을 표현하려는 '죽음의 예술화'가 생략되어 있는 것이 특징이다. 이것은 한 인물이 죽음에 이르는 과정을 다루는 것에서 벗어나 주변 인물의 반응이라든지 죽음 이후의 이야기 전개에 더 큰 관심을 기울이게 되는 서사적 차원에서의 변화로 이어진다. 이러한 변화는 죽음의 미적 인식에 관한 작가의 전면적인 태도 변화와 관련이 깊다. 1920년대 중반 염상섭의 산문에서는 죽음에 대한 미화가 일본적인 미의식과 깊이 연관된 것임을 강조하고 있는데, 이를 볼 때 죽음에 대한 인식의 변화는 일본적인 감수성에서 탈피하려는 작가의식의 소산임을 알게 된다. 또한 죽음을 계기로 인간의 내면 탐색을 추구하려는 시도가 약화된 자리에는 민족이나 사회에 대한 관심이 대체되고 있다는 점을 확인할 수 있었다. This thesis researches on the figure of death in Sangseop Yeom's fictions. Until now, researchers regard Yeom as the representative of the realist writers in Korean literature. So the theme of death in Yeom's fictions is untouched. In Yeom's fictions that were presented in early 1920s, death means entering a state of enlightenment. Death is not the termination of life, but the entrance of new stage that is filled with metaphysical value like truth, goodness, and beauty. This imagery about death seems the results of influence by romanticism. Yeom bethought how to make art with the subject matter of death. He came to a conclusion that death in itself is part of nature but passing through writers subjective, death can be part of art. The meaning of events is reduced to the lowest minimum and death is the medium that leads a person to introspection. Meanwhile, the figure of death in Yeom's works that were presented in 1930s went through a lot of changed. He did not make a mystery of death; consequently, death is treated as event for unfolding the plot. In mid-1920s, Yeom realized that the aesthetic of death have relevance to Japanese traits. (E.g. Japanese enjoy going cherry-blossom viewing and admiring the falling blossoms as the symbol of death) So the changes about the figure of death inform us that Yeom took a position contrary to Japanese sensibility. Furthermore, we can confirm that attempt to introspect with the theme of death is substituted with research on the reality of colony.

Poster Session:PS 1203 ; Cardiology : Predictive Factors of Reversibility in Patients with Severe Tricuspid Regurgitation

( Jae Yeong Cho ),( Kye Hun Kim ),( Kyung Jin Lee ),( Yi Rang Yim ),( Sung Soo Kim ),( Hae Chang Jeong ),( Ki Hong Lee ),( Keun Ho Park ),( Doo Sun Sim ),( Hyun Ju Yoon ),( Nam Sik Yun ),( Young Joon 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background:Since severe tricuspid regurgitation (TR) is an uncommon fi nding which develops in various conditions, the present study aimed to investigate etiology, clinical characteristics, and predictors of reversibility in patients with severe TR. Methods:A total of 232 patients (67. 4±14. 1 years, 80 males) who were diagnosed with severe TR by echocardiography were enrolled. Severe TR was defi ned as vena contracta width greater than 0. 7 cm and systolic fi ow reversal in hepatic veins according to the current guideline of American Society of Echocardiography (ASE). Improvement of TR to moderate or less degree on follow up echocardiography was considered as reversible TR in the present study. Primary end points were adverse events at long-term follow-up. Adverse events were defi ned as all-cause death and operation due to severe TR. Results: Reversible TR was observed in 35 out of 153 patients (23. 0%). Sixty-one patients showed clinical improvement, but the degree of TR was not changed. Forty-nine patients (32%) who did not show clinical improvement despite of medical therapy eventually underwent surgical correction of TR, and 7 patients died. In addition, 17 patients died without operation, so 24 deaths (16%) were observed in total. finally, total adverse events developed in 66 patients (41%) during 2 years of follow-up period. Logistic regression analysis revealed prosthetic mitral valve was the only independent predictors of future adverse events (OR 2. 47, 95%CI 1. 05-5. 77, p=0. 038). Independent predictors of improved TR turned out to be the use of RAAS blockade (HR 3. 02, 95%CI 1. 12-8. 17, p=0. 030) and the use of spironolactone (HR 3. 39, 95%CI 1. 05-10. 90, p=0. 041). Low ejection fraction (LVEF <50%) also had a trend toward the reversibility (HR 2. 82, 95%CI 0. 94-8. 40). Conclusions:Considering results above, reversible severe TR mainly associated with left heart failure and medical treatment should be given before considering surgery for severe TR.
