  • 온실가스 에너지 목표관리제도 뿐만 아니라 배출권거래제도도 도입을 준비하고 있는 등 외부에서 제도의 압박이 거세지고 있다. 기업에서는 온실가스 감축과 관련하여 조직 전부문이 참여하는 실질적 에너지경영체계를 구축해야 하며 조직 외부와 에너지 감축기술에 대한 커뮤니케이션 네트워크를 구성하는 등 기후변화에 대한 대응이 필수적인 사항이 되었다. 이제는 규제대응을 넘어 미래 전략 차원에서 접근과 노력을 해야 한다.

  • External social support for family can be an important resource for families to overcome economic pressure, and can be a way to understand the concept and process of family resilience in the context of Korean economic crisis. To explore the role of external social support that alleviates the negative effects of economic pressure on marital satisfaction, the buffering effects were tested in two ways. First, the interaction effect between external social support and economic pressure on marital satisfaction was tested using hierarchical linear regression model. Second, the scores of marital satisfaction were plotted by the median scores of economic pressure and external social support. Results from the analyses of 191 couples (382 husbands and wives) indicated that external social support help families by buffering the negative effects of economic pressure on marital satisfaction by interacting with economic pressure.

  • Purpose : Infants and children with cardiovascular diseases often present with respiratory symptoms. However, missed or delayed evaluation for potential airway problem may complicate overall prognosis. The aim of this study is to determine the clinical characteristics of these patients and explore the cause of airway problem. Methods : We reviewed the medical records of 64 patients(M : F=33:31, mean age : $6.3{\pm}7.5$ months) whose airway problems were proven by computed tomography or bronchoscopy in perioperative periods at the Asan Medical Center from January 1997 to June 2004. Patients were divided into two groups based on the duration of ventilator care : ${\leq}7$ days(group 1 : 23 cases, M : F=10 : 13) and >7 days(group 2 : 41 cases, M : F=23 : 18). Results : The patients in group 2 significantly developed more post-operative respiratory symptoms than group 1(P<0.001) and had more airway problems including extrinsic obstruction, intrinsic anomaly, and combined problem than group 1 although not significantly different(P=0.082). Among underlying diseases, the most common diseases were vascular anomaly(26.2 percent) and aortic arch anomaly(26.2 percent) in group 1 and pulmonary atresia with ventricular septal defect(22.4 percent) in group 2. The most frequent respiratory symptoms were recurrent wheezing pre-operatively and failure of ventilator weaning post-operatively. The major types of airway anomaly were tracheomalacia and tracheal stenosis(in each case 18.2 percent). Nineteen patients with persistent airway problems underwent aortopexy or other vascular correction. Of the 19 patients, 13(68.4 percent) were improved, but 2 failed in weaning ventilator and 4 died of non-airway problems. Conclusion : Early evaluation and treatment for potential airway problems may affect natural or surgical prognosis in patients with cardiovascular diseases presenting with respiratory symptoms.

  • Nerve compression is caused by external force or internal pathology, which symptom develops along nerve distribution. There are median, ulnar and radial nerve compression neuropathies below elbow. Carpal tunnel syndrome at the flexor retinaculum is most common among all the entrapment neuropathies. Other causes of median nerve neuropathy include Struther's ligament, biceps aponeurosis, pronator teres, FDS aponeurosis and aberrant muscles, which induce pronator syndrome or anterior interosseous nerve syndrome. Ulnar nerve can be compressed at the elbow by arcade of Struther, medial epicondylar groove, FCU two heads, which develops cubital tunnel syndrome, at the wrist by ganglion, fracture of hamate hook and vascular problem, which develops Guyon's canal syndrome. Radial tunnel syndrome is caused by supinator muscle, which compresses its deep branch. Treatment is conservative at initial stage like NSAID, night splint or steroid injection. If symptom persists, operative treatment should be considered after electrodiagnostic or imaging studies.

  • CT scan is reported to have a high risk of cancer due to a relatively high dose among medical radiological examinations. In particular, exposure to radiation to the breast, which is sensitive to radiation, is inevitable during a chest CT scan for female patient. In this study, the dose reduction effect of wearing a compression band during chest CT scans in women was evaluated, and the lifetime attributable risk due to the effective dose exposed during the CT scan was estimated. As a result, when the compression band was used, the effective tube current decreased as the outer perimeter of the chest became smaller, and it was analyzed that the CT dose index and effective dose were also reduced. In addition, the lifetime attributable risk by chest CT scan was found to reduce the cancer risk by 3.2 per 100,000 for all cancers, 0.2 per 100,000 for solid cancer, and 0.8 per 100,000 for breast cancer, based on women in their 30s when using a compression band. It is judged that the risk of cancer can be reduced through the use of appropriate scan parameters and dose optimization measures such as compression bands for future CT examinations.

  • 10개월경의 그리폰 벤딘 수컷 강아지가 8개월경부터 점점 운동 실조 및 마비증상을 나타내어 머독대학 동물병원에 내원 하였다. 내원 했을 때 주변에 매우 민감한 반응과 경계를 늦추지 않았지만 호흡과 심박수 및 체온은 정상이었다. 일반 방사선 사진 및 척수조영사진(myelography)을 촬영하여 확인한 결과 환축추의 불안정에 따른 척수의 복측 압박을 확인할 수 있었다. 외과적 고정은 복측 접근을 통하여 2개의 키르크너 강선(Kirschner wire)과 자가골이식을 실시하였으며 8주동안 외부 고정을 하였다. 수술 후 5개월 동안 지켜본 결과 증상은 꾸준히 좋아졌으며 환축추 관절으 관절고정술(arthrodesis)은 완벽한 고정을 유지하고 있었다.

  • 일본 자동차 유통계열 구조에 변화의 조짐이 일어나고 있다. 가전 부문의 유통계열이 신유통업태의 정장이라는 외부적 요인에 의해 변화되었다면, 자동차 유통계열은 내적ㆍ외적 요인의 상호작용에 의해 그 문제점이 노정되고 있다. 내적인 요인으로는 메이커의 경직적인 도매가격 운용을 들 수 있는데, 이는 딜러 경영을 압박할 뿐만 아니라 메이커-딜러간 갈등을 야기하는 주된 요인이 되고있다. 한편 급속한 정보화는 딜러의 할인판매 경쟁만 가속시킬 뿐 유통계열의 개선에는 유용성이 없는 것으로 분석된다. 장기적으로는 자동차 유통계열의 내부적 모순이 점차 가시화되고 정보화가 확산됨으로써 정차 변화할 것으로 예상된다. 한국 국자동차기업은 이러한 유통계열의 약점을 전략적으로 이용하면서 차별화된 제품으로 승부하는 전략을 구사하는 것이 바람직할 것이다.

  • The purpose of this study is to investigate the change of the EGFR mRNA expression in the rat gingival epithelium by the experimental tooth movement. We applied reciprocal force between the upper anterior teeth using NiTi open coil spring and stainless steel wire for 1, 2 3, 7 days. For the detection of EGFR mRNA, in situ hybridization was done in the tissue samples which were taken from the pressure and tension sides of teeth. The results were as follows ; 1. The expression of EGFR mRNA was increased application-time dependently. a. Day 1 mild expression on the basal and spinous cell layers b. Day 2 . moderate expression on the whole layers c. Day 3 : severe expression on the basal and spinous cell layers 4. Day 7 severe expression on the whole layers 2. The expression level of EGFR mRNA in the pressure and tension sides were similar during the whole Period of experiment except seven day application at which the cornified layer of the tension side showed moderate expression. 3. Removal of the appliance after 7-day force application lowered the level of EGRF mRNA expression. It was returned to the mild and control (rare) level at three and seven days after the removal, respectively. In conclusion, EFGR mRNA was increased by the experimental tooth movement on the rat ginigval epithelium. Up-regulation of EGFR mRNA in the gingival epithelium can be regarded as responses to the possible changes caused by the physical stersses to the oral environment to maintain the homeostatic conditions of the periodontium.
