The results of large-scale clinical studies have shown that the lung cancer mortality rate can be reduced by lung cancer screening using low-dose computed tomography (LDCT) in high-risk populations. Lung cancer screening requires rigorous quality control to ensure that imaging can be introduced into evidence-based medical systems and that results can be effectively delivered to examinees. Cessation of smoking is indispensable for reducing mortality in parallel with lung cancer screening. Pulmonary nodules found in LDCT during the Korean National Lung Cancer Screening are categorized according to their characteristics, size, and time of discovery based on the Lung Imaging Reporting And Data System (Lung-RADS); management guidelines are followed according to categorization. To improve the efficiency of lung cancer screening, studies are currently ongoing to enable selection of high-risk groups using lung cancer prediction models and biomarkers. Based on the risk estimation classification of lung cancer, it is expected that the selection of screening subjects and the screening cycle can be differentiated, which will increase the efficiency of screening, reduce the risk of unnecessary radiation exposure, and reduce the cost of screening.

본 연구는 조직에서 구성원들의 조직동일시가 지식공유행동에 미치는 영향과 직업적 자기효능감의 매개효과를 실증적으로 검증하기 위해 수행되었다. 특히 지식공유행동은 세 가지 하위요인(서면기여, 조직내 의사소통, 구성원 상호작용) 각각에 대한 주 효과와 매개효과를 검증하였다. 연구 결과, 조직동일시가 지식공유행동에 긍정적인 영향을 미친다는 가설은 지식공유행동의 하부요인 별로 차이가 있었다. 조직동일시의 서면기여에 대한 영향은 유의하지 않은 반면, 조직 내 의사소통과 구성원 상호작용에 대한 영향은 통계적으로 유의하였다. 조직동일시와 지식공유행동의 관계에 있어 직업적 자기효능감이 매개효과는 부분적으로 지지되었다. 본 연구는 다음의 시사점을 가지고 있다. 첫째, 이론적으로는 조직동일시 개념의 모태가 되는 사회정체성 이론과 조직정체성에 대해 살펴보고 조직에서 구성원의 지식공유의 딜레마를 완화할 수 있는 요인을 집단참여모델을 통해 설명하고자 하였다. 둘째, 국내연구에서는 드물게 최근에 개발된 지식공유행동 측정도구를 활용하여 연구를 진행함으로써 측정도구의 타당성과 신뢰성을 국내표본을 통해 살펴보고, 기존 측정도구보다 다차원화된 측정도구를 사용하였다. 셋째, 조직성과에 많은 잠재적인 영향력을 지니고 있음에도 연구가 제한되었던 조직동일시와 지식공유행동과의 관계를 살펴보고 이 관계에서 직업적 자기효능감의 매개효과를 실증하였다. 또한 실무적 시사점으로 지식공유의 하위변인 중 조직 내 의사소통과 구성원 상호작용과는 다르게 서면기여는 조직동일시와 유의한 관계가 증명되지 않았는데, 이러한 결과는 조직 내에서 지식공유를 활성화하기 위해서는 조직동일시와 같은 구성원의 심리적인 과정에 대한 관심과 함께 지식관리 시스템의 구축, 적절한 보상체계가 갖추어 져야 함을 보여준다. The purpose of this study is to examine influences of organizational identification on employees’ knowledge sharing behavior which is composed of written contribution, organizational communications and personal interactions. And also this study has verified the mediating effect of occupational self-efficacy between organizational identification and knowledge sharing behavior. The samples are obtained from pilots who are serving in ROK Air Force fighter squadrons and analyzed by using AMOS and SPSS program. The results of this study are as follows. First, organizational identification has a positive effect on organizational communications and personal interactions. However, organizational identification does not impact on written contribution. Second, occupational self-efficacy acts as a complete mediator between organizational identification and organizational communications and as a partial mediator between organizational identification and personal interactions. The last part of this study summarizes all the results and provides the contribution and implications of this study. And directions for future studies are discussed.

Pancreas acinar cell carcinoma (ACC) accounts for only 1-2% of pancreatic exocrine malignant tumor. The symptoms of patients with ACC are usually non-specific, for example the anorexia and weight loss. Patients may develop Schmid`s triad including subcutaneous fat necrosis, polyarthritis, and eosinophilia. We reported a case of ACC which was manifested by subcutaneous nodule as initial clinical symptom. To our knowledge, this is the first reported case of ACC presenting as subcutaneous fat necrosis in Korea. (Korean J Gastroenterol 2010;55: 139-143)

Though many researches have been conducted on the enhancement of competitiveness through the introduction of SCM in the recent automotive industry, most of them are on the finished car manufacturers and the first-tier suppliers while the researches on the first-tier suppliers and the sub-tier suppliers, on the strategies for the promotion and support of the sub-tier suppliers are insufficient very much. This research found out that the methods to secure the competitiveness of the first-tier and the sub-tier suppliers lied in the mutual trust and cooperation between the first-tier suppliers and that the sub-tier suppliers and in particular, the promotion program for the sub-tier suppliers should give priority to the policy for purchase and promotion from a long-term perspective, and that the support for management innovation, the joint development of technology and technology improvement, the maintenance of competing relations through collaboration, and the cultivation of talented personnel should be necessary, and that the sub-tier suppliers also should secure the quality and cost competitiveness through participating in the promotion program. This research will be the role model not only the automotive industry but also other industries about what roles they have to provide with regards to the promotion and support for their first-tier suppliers and the sub-tier suppliers.

Objectives : The purpose of this study is to report the clinical effects of Korean medical treatment with Hominis Placenta Pharmacopunture(HPP) on cold hypersensitivity of hands. Methods : A 46-year-old female patient whose chief complaint was cold hypersensitivity of hands was treated with Placenta Pharmacopunture at LI4 and LI10, ten times for a month. Acupuncture and herbal medicine were added depending on the symptoms. Digital Infrared Thermal Imaging(D.I.T.I) was taken and Visual Analog Scale(VAS) was examined before and after each treatment. Results : After the treatments, the symptoms were improved. Conclusions : DITI and VAS showed that the patient’s cold hypersensitivity of hands was improved after Korean medical treatment with Hominis Placenta Pharmacopuncture.
