본 논문은 기업의 지속적인 경쟁우위 요소로 관심을 받고 있는 공유가치창출(CSV)과 사회적 성과, 협력기업성과에 미치는 파급효과를 인공신경망(Artificial Neural Network) 분석방법을 중심으로 분석하고자 한다. 연구대상은 항공제조기업의 근무자를 대상으로 설문 조사를 실시, 234부를 최종분석에 사용하였다. 분석방법으로 기존의 구조방정식(AMOS)의 경로분석과 인공신경망(ANN) 분석방법을 비교하고 이에 따른 ANN 분석방법이 주는 의미와 시사점을 제시하였다. 분석결과, CSV의 하위요인인 경제적가치, 환경적가치, 사회적가치가 사회적성과 및 협력기업성과에 미치는 영향을 AMOS를 통한 경로분석결과와 ANN분석결과 CSV의 하위요인과 사회적성과 및 협력기업성과 간에는 유의미한 긍정적 관계가 있는 것으로 밝혀졌다. 결과적으로 AMOS를 활용한 분석방법의 선형적 연구결과와 달리, ANN분석방법을 통한 연구결과는 비선형적 연구결과를 보여주었으며, 이러한 연구논문의 결과를 바탕으로, 기업이 CSV활동을 통해 사회적성과와 협력기업성과를 달성할 수 있는 동반성장전략임을 규명하고 있으며, 의미 있는 학문적, 실무적 시사점을 제시하고 있다. This paper aims to analyze the ripple effect on the creation of shared value (CSV), social performance, and partner company performance, which are attracting attention as an element of continuous competitive advantage of companies, focusing on the analysis method of artificial neural networks. The subject of this study was a questionnaire survey for workers in aviation manufacturing companies, and 234 copies were used for the final analysis. As an analysis method, path analysis of the existing structural equations and artificial neural networks (ANNs) analysis methods were compared, and the meaning and implications of the ANNs analysis method were presented. As a result of the analysis, the impact of the sub-factors of CSV, such as economic value, environmental value, and social value, on social performance and partner business performance, was determined between the results of path analysis through AMOS and ANNs analysis results. It was found that there was a significant positive relationship. As a result, based on the results of this research paper derived through the ANN analysis method, it has been identified as a win-win growth strategy that enables companies to achieve social and partner business performance through CSV activities, and has meaningful academic and practical implications. Are presented.

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

The purpose of this study is to invesetigate the clinical significance of initial enlargement of ventricle in the patients who had aneurysmal SAH. Of the total 821 patients with aneursmal SAH who were registerd in SAH data bank system between 1989-1999, 307 patients who had been already measured in the size of ventricle at the time of admission, were studied retrospectively. The size of ventricle was calculated by bifrontal index. Normal size of ventricle was defined as 30% or less, mild enlargement was defined as 31 to 39%, and moderate enlargement of vertricle was defined as more than 39% in bifrontal index. The sizes of ventricle using bifrontal index were analysed according to the age, sex, blood pressure, consciousness at admission, medical history of hypertension, location of ruptured aneurysm, Fisher's grade on CT(computerized tomography) scan at the time of admission, cerebral vasospasm, intraventricular hemorrhage (IVH), performance of external ventricular drainage (EVD), and prognosis at discherge. Chi-square test and ANONA were used in the statistical evaluation. The results were as follows : 1) Of the 307 patients, 235(76.5%) had a mild to moderate enlargement of ventricle at the time of admission (more than 30% in bifrontal index). 2) The size of ventricle was enlarged according to the increase of age (p<0.05). 3) In the patients who had ruptured aneurysm on anterior cerebral artery, the size of ventricle significantly increased and showed a higher incidence in mild enlargement compared with moderate enlargement of ventricle (p<0.05). 4) The size of ventricle increased in th patients who had IVH and the EVD was more frequently performed in th patients who had the enlarged ventricle associated with IVH (p<0.05). 5) In the patients who had high Fisher's grade, the size of ventricle had a tendency to increase, but there was no statistical significance. 6) In the patients who had poor prognosis, the size of ventricle had a tendency to increase, but there was no statistical significance. Conclusively, the initial size of ventricle was enlarged in th aged patients, ruptured aneurysm on anterior communicating artery, high FIsher's grade, patients associated with IVH. Considering those factors, prediction for the enlargement of ventricle size may help to treat the patients suffering aneurysmal SAH.

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.

아조벤젠 그룹을 포함한 측쇄형 고분자 필름(PDR1)에서 광 유도된 이방성을 실시간적으로 조사하였다. 수평, 수직한 흡수율의 변화를 광 유도된 복굴절의 기록, 감쇠, 소거, 완화 과정에 따라 측정하여, 매질 내의 아조벤젠 분자의 정렬상태와 복굴절과의 관계를 광 이성화과정으로 설명하였다. 또한 기록빔의 세기를 따른 수직, 수평한 흡수율의 변화와 유도된 복굴절의 관계를 조사하였다. The photo-induced anisotropy for a polymeric film(PDR1) containing azobenzene group as side-chain was investigated dynamically. The change of absrobances with parallel and perpendicular components was measured in recording, decaying, erasing and relaxation processes of photo-induced birefringence, so the relation between the alignment of azobenzene groups and the birefringence was well explained according to the photo-isomerization. Also, the dependence of the photo-induced birefringence on intensity of recording beam was investigated with changes of both absorbance and birefringence.

본 연구는 인지내용이 정서장애에 영향을 미친다는 인지적 내용-특수성 가설에 근거하여 불안장애환자의 사고내용을 조사하고자 했다. 사고내용에 있어서, 불안장애 환자들이 정상인 또는 비불안 정신장애환자와 어떤 차이점이 있는지를 조사했으며 나아가서 불안장애의 하위유형인 공황장애환자와 비공황 불안장애환자간에 어떤 차이점이 있는지를 탐색하고자 했다.이를 위해서 공황장애환자 34명, 비공황 불안장애환자 24명, 비불안 정신장애환자 34명을 포함한 92명의 정신장애 환자와 60명의 정상인을 대상으로 하여 그들의 사고내용을 측정하였다. 이들의 사고내용은 불안민감성 척도(ASI), 광장공포인지 질문지(ACQ), 신체감각 질문지(BSQ)를 사용하여 측정되었다. 각 집단별 사고내용을 정밀하게 비교하기 위하여 각 척도의 개별문항에 대해서 차이비교검증을 실시하였다.본 연구의 주된 결과는 다음과 같다. 첫째, 공황 장애를 비롯해 불안장애 환자집단은 정상인 집단에 비해 세 척도에서 측정된 불안유발 사고내용을 현저하게 많이 가지고 있었다. 둘째, 공황장애 환자집단은 비불안 정신장애 환자(우울증 및 신체화) 집단에 비해 신체적 증상에 대해서 더 예민하고 이를 위협적인 것으로 평가하는 경향성이 있었다. 셋째, 공황장애 환자들은 비공황 불안장애 환자나 비불안 정신장애환자에 비해 극단적이고 파국적인 위험과 관련된 사고내용을 많이 가지고 있었다. 특히 공황장애 환자들은 다양한 신체적 증상과 변화에 예민하고 이를 죽음이나 통제상실상태와 같이 극단적이고 파국적인 것으로 해석하는 사고경향이 있는 반면, 비공황 불안장애 환자들은 대인관계에서의 부적절한 대처나 능력에 대한 부정적 평가와 같이 일반적이며 비파국적인 위험이나 위협과 관련된 사고내용을 많이 갖는 경향이 있었다.ABSTRACT The aim of the present study is to investigate some characteristics of patients with anxiety disorders in their thought contents from the theoretical perspective of the cognitive content-specificify hypothesis that cognitive contents influence emotional disorders. For this, differences in thought contents between patients with panic and non-panic anxiety disorder as well as between patients with anxiety disorders and non-anxiety psychiatric patients or nomal controls were examined.The data were collected from 92 psychiatric patients (34 panics, 24 non-panics, 34 non-anxiety psychiatric patients) and 60 normal controls. Their thought contents were measured with the Anxiety Sensitivity Inventory, Agoraphobic Cognition Questionnaire, and Body Sensation Questionnaire. The difference between groups in the individual item of the three measures was tested using ANOVA and multiple comparison tests.The main findings in the present study are as follows: First, the patients with anxiety disorders reported significantly more thoughts with anxiety-provoking contents than normal controls. Second, the patients with panic disorders tended to be more sensitive to physical symptoms and to interpret these as being threatening than the non-anxiety psychiatric patients. Third, the patients with panic disorder had more thoughts with contents related to extreme and catastrophic danger than those with non-panic anxiety disorders. In particular, those with panic disorder had strong tendency to be senstive to physical symptoms or changes and to interpret these as suggesting extreme and catastrophic danger such as death or loss of control, whereas those with non-panic anxiety disorders tended to have thoughts with contents related to general and non-catastrophic danger or threats such as inadequate coping in interpersonal situations or negative evaluation about their ability.

교정치료와 악교정 수술을 필요로 하는 환자가 점증하는 현 시점에 비추어, 이에 대한 기술적인 측면의 발전과는 달리 수술-교정 치료 환자에 대한 정신사회학적 혹은 정신심리적 양상에 대한 객관적인 정보는 그리 많은 주목을 받는 편이 아니었다. 수술-교정치료는 과학적인 치료과정이긴 하지만, 어느 정도 심미적 혹은 예술적인 측면을 지니는 선택 치료의 면모를 지닌다. 그러므로 치료에 대한 환자의 주관적인 느낌은 치료 기술이나 치료의 의학적 성공 여부보다 더 큰 영향을 미칠 수 있다. 그러므로, 수술-교정 (혹은 교정) 치료에 대한 환자의 반응을 예측하기 위한 정신심리적인 정보는 치료에 유용한 지표가 될 수 있다고 가정할 수 있다. 통제 소재에 대한 연구는 인간의 다양한 행동을 예측하기 위한 유용한 지표로 알려져 왔는데, 본 연구에서는 42명의 수술-교정치료 환자와 성별/연령별로 표본 추출된 42명의 통상적 교정치료 환자를 대상으로 삼아 정신=심리적 비교 및 분석의 방법으로 두 가지 종류의 내외 통제 소재(internal/external locus of control) 검사를 시행하였다. 그 결과 수술-교정치료군에서만 남자가 여자에 비하여 낮은 외적 통제(높은 내적 통제)의 경향을 보였다. 결론적으로 수술-교정치료 환자의 정신심리적 기반은 성형 수술 환자와는 달리 교정치료 환자와 유사한 경향을 지닌 것으로 생각되었다. Surgical-orthodontic treatment is an increasingly more common dental procedure whose unique psycho-social or psychological feature has not been fairly quantified objectively. Since the treatment of a surgical-orthodontic (or orthodontic) patient is part science and part art, a subjective recognition of a patient about his or her own treatment may be more important than technical success during and after treatment. Therefore, the knowledge of the patient''s underlying psychological status could be useful in the prediction of patient's response to surgical-orthodontic (or orthodontic) treatment. The purpose of this study was to investigate and evaluate the psychological difference between conventional orthodontic patient and surgical-orthodontic patient by using locus of control (LOC) examination. Locus of control scale has been proven to be extremely useful in the prediction of a variety of human behaviors. Two types of locus of control data (I-score, Internal locus of control score ; E-score, External locus of control score) were obtained for 42 surgical-orthodontic patients and randomly selected 42 conventional orthodontic patients (as a control group) matched for age and gender. No statistically significant difference was observed in the scale of internal and external locus of control between the groups of surgical-orthodontic patients, males showed lower E-score (external locus of control score, higher internal locus of control tendency) than females. The results of this study suggested that the psychological background of surgical-orthodontic patients, in contrast with that of cosmetic surgery patients, has a similar disposition with that of orthodontic patients.
