국내 건설경기는 주택경기 침체, 글로벌 금융위기 등의 영향으로 2008년부터 본격적인 침체가 최근까지도 지속되고 있으며, 장기화되고 있다. 이러한 어려움을 타파하기 위해 건설기업에서도 서비스기업과 같이 내부마케팅 활동을 강화시켜야 한다. 하지만 건설기업은 기존의 서비스기업과 달리 직접적으로 고객을 응대하지 않을 뿐 아니라 건설 현장이라는 특수한 상황에 처해 있어 적극적 내부마케팅 활동 강화가 쉽지 않은 상황이다. 따라서 내부마케팅 활동 중 우선순위를 선정하여 가장 시급한 부분부터 개선해 나아가야 한다. AHP 분석 결과 1계층에서 내부 의사소통이 가장 우선적으로 강화시켜야 할 요소로 나타났으며 그, 다음으로 근무조건 및 환경으로 나타났다. 그 다음 각각의 상위 개념별 하위 활동을 보면 내부 의사소통에서 상사와의 의사소통을, 근무조건에서는 일일 근무시간 전반적 만족을, 보상 및 포상에서는 수주 기여 시 보상으로 나타났다. 교육훈련에서는 전문가들의 의견 일치를 보지 못하였다. In recent years, the domestic construction business is continuously stagnated caused by housing depression, global financial crisis etc. To overcome these difficulties, the construction companies should reinforce the internal marketing like the service business. However, it is not easy to conduct active internal marketing reinforcement since the companies do not directly receive customers under special situation like construction. Therefore, it is necessary to resolve the urgent issue by selecting order of priority among internal marketing factors. To address this issue, the objective of this study is to analyze the internal marking factors by using Analytic Hierarchy Process. As a result, the first and second factor represents the internal communication and working condition and environment respectively. The findings of this study will contribute to apply the internal marketing into construction industry.

Recent economic slump is making the construction industry's overall construction business environment worse. Contractors which are under the legal management and/or walk out are to the brink of 25 companies according to the Construction association of Korea released in 2011. It means that existing construction companies are required to transform the fundamental ideology of existing operation framework, and besides, existing companies should be transformed to service industry in order to proceed further into the developing future industries. In this study, it will be chosen the internal marketing related factor like 'Satisfying employees, internal customer, are the first thing to do in order to satisfy external customer.' which is about existing service industry field before its implementation in construction companies. In addition, appropriateness test will be performed including both interactions between each of the factors affect mutually and looking into any management improvement effects on contractors. And also, this proposal is suggested by approaching with internal marketing strategy which is both paradigm shift for customers by construction company members and another internal communication way as a means of overcoming the crisis of overall construction industry under currently happening. 최근 경기침제는 건설 산업의 전반적 건설기업환경을 악화시키고 있다. 2011년 대한건설협회 발표에 따르면 2008년 이후 워크아웃 및 법정관리 중인 건설사는 25개사에 이른다. 이는 기존 건설기업을 운영하는 틀과 사고((思考)에 대한 근본적인 변화를 요구하는 것이다. 지금부터 건설 산업은 서비스업이 되어야 하며, 또한 미래 성장산업으로 뻗어나가려면 서비스업으로 변신해 나가지 않으면 안 된다. 이에 본 연구는 기존 서비스산업분야의'외부고객의 만족을 위해서는 내부고객인 종사원의 만족이 우선이다.' 라는 내부마케팅을 건설기업에 시행(도입, 적용) 및 활동에 앞서 내부마케팅관련 구성요인을 선정하려한다. 또한 각 구성요인들 간에 어떠한 영향을 미치며, 시공사에 기업성과가 있는지 검정하려한다. 그리고 그동안 등한시 하였던 건설기업 구성원의 고객 지향(의식, 인식)적 사고의 전환 도구로, 내부 소통의 도구로 또한 현재 처하고 있는 건설 산업의 위기를 극복하기 위한 방편으로 건설기업에도 내부마케팅의 시행 및 활동을 제안 하고자 한다.

The anthropometric characteristics of the intended user population are most important parameters in the equipment and workplace layout design, particularly in the airplane cockpit design. Because human body is composed of multi-dimensional body segments, single 'average' or 'extreme' manikin is not sufficient in computer-aided design(CAD) environments. To overcome this limitation, we constructed a manikin group representing Korean Male pilot population. First, we identified 16 anthropometric variables which are important parameters in the evaluation of reach, visibility, and clearance. And we found their correlations and conducted a factor analysis. Four common factors were extracted in the factor analysis. The first one was related with length dimensions, the second was with the arm reach, the third was with the sitting height, and the last was with breadth-depth dimensions. Finally, 17 manikins were constructed and presented in the CAD prototype.

레일강의 균열발생·천이 및 피로균열진전거동

궤도용 차량의 안전성 확보를 위한 연구의 일환으로서 레일강의 균열 발생 조건과 모재와 용접부에 대한 정적파괴거동 및 단일모드 하중하의 피로균열진전거동을 검토하였다. 레일에서 횡방향 균열의 원점은 표면하층균열이며 이는 최대전단응력에 의해 발생하였다. 또한 표면하층균열의 크기가 증가함에 따라 균열의 진전은 전단모드에서 혼합모드로 천이될 가능성이 증가하였다. 용접부의 평면변형률 파괴인성은 조직의 조대화와 경도의 상승으로 인하여 모재에 비하여 약 10% 저하하였다. 용접부의 제 2단계 영역의 피로 균열진전속도는 낮은 ${\Delta}K$ 영역에서 모재에 비하여 저하하였으나 높은 ${\Delta}K$영역에서는 이의 차이가 소멸되었으며 이러한 경향은 R=0.1의 낮은 응력비에서 현저하였다. 이는 용접부의 미시조직이 모재에 비하여 성장하였기 때문이라고 판단된다. In the present study, crack initiation criteria, static failure and tensile mode fatigue behavior for a rail steel are evaluated to assure the railway vehicle's safety. The transverse fissure, which is the most critical damage in the rail, is initiated by the maximum shear stress and its location is subsurface. In addition, the possibility of transition from the shear mode to the mixed mode increases with increasing the length of subsurface crack. Because of the brittleness by the welding, the fracture toughness of the welded part is lower than of the base metal. For low ${\Delta}K$, the stage II fatigue crack growth rates of the welded part is slower than of the base metal but, for high ${\Delta}K$, this different behavior for fatigue crack growth rate is nearly diminished. These trends are more remarkable for low stress ratio, R=0.1. It is believed that this behavior is caused by the change of the microstructure which that of the welded part is coarser than of base metal.

단백질의 Maillard 반응의 최종산물인 CML 형성에 미치는 ROS의 영향

이종선(Jong-Sun Lee),양융(Ryung Yang),신동범(Dong Bum Shin) 한국식품영양과학회 2004 한국식품영양과학회지 Vol.33 No.1

단백질의 Maillard 반응의 최종산물의 하나인 N^ε-carboxy methyl lysine(CML)의 형성에 미치는 reactive oxygen species(ROS)의 영향을 살펴보았다. Glucose와 fructose는 자동산화과정을 통하여 CML형성의 주된 propagator인 α-dicarbonyl 화합물은 물론 glyoxal을 생성시키는 것이 확인되었다. 또한 이 과정은 ROS를 형성하는 천이금속이온에 의해 촉진되는 산화과정임을 알 수 있었다. 반응성이 높은 fructose에 비해 glucose의 경우가 ROS의 영향이 더욱 현저하게 나타났다. 불포화 지방산도 glyoxal을 형성하고 있었으며, 불포화도가 클수록 glyoxal 생성량이 빠르게 나타났으나 ROS의 영향은 비교적 작게 나타났다. Ascorbic acid 역시 ROS와는 무관하게 glyoxal을 생성하였다. 이는 ROS의 영향 이전에 이들 물질들의 반응성이 매우 높다는 것을 의미하고 있다. Hippuryl lysine을 이용한 model system에서도 glucose로부터의 N^ε-carboxymethyl hipuryllysine(CMHL) 형성에는 ROS의 영향이 높게 나타났으나, 반응성이 매우 높은 glyoxal에 의한 CMHL 생성에는 ROS의 영향이 거의 나타나지 않았다. CML에 특이적으로 결합하는 monoclonal antibody (6D12)를 이용한 antigen coated noncompetitive indirect ELISA 분석을 통해서 CML생성에 미치는 ROS의 영향을 살펴본 결과 대체로 위의 결과와 비슷한 경향을 나타내었다. 따라서 반응성이 높은 물질일수록 CML 형성에 ROS의 영향이 작게 나타남을 알 수 있었다. The effect of reactive oxygen species (ROS) on the formation of N^ε-(carboxymethyl)lysine (CML), one of the endproducts in the Maillard reaction of protein (or glycation), was investigated. Glyoxal, a main precursor of CML formation, was produced from both glucose and fructose during their autoxidation. The transition metal ion showed to involve in the formation of glyoxal by the metal catalyzed oxidation, suggesting that ROS accel-erated the reducing sugar autoxidation. The stimulative effect of ROS on the autoxidation was more prominent in glucose than in fructose. Polyunsaturated fatty acids (PUFAs) were shown to form glyoxal by peroxidation in proportion to the degree of unsaturation, but ROS did not affect on PUFA peroxidation. Ascorbic acid also showed the similar pattern as of fructose due to its autoxidation. The formation of N^ε-(carboxymethyl)hippuryl lysine (CMHL) in the model system using hippuryl lysine and glucose had a significant effect on ROS, whereas it had no effect on ROS using glyoxal as a reactant. Almost the same trend was obtained by the analysis of antigen coated indirect noncompetitive ELISA using monoclonal antibody (6D12). These data indicated that ROS affected glucose autoxidation as well as mediated both CML and glyoxal formation, but did not affect the reactive compounds such as fructose, PUFAs and ascorbic acid.

Background: Basal cell carcinoma in Korea is the most common skin cancer and its incidence is increasing at a steady rate. It is not unusual for dermatologists to experience the recurrence of tumor after surgery but there is no data on recurrent basal cell carcinoma in Korea. Objective: The aim of this retrospective survey was to determine the clinical and histopathological characteristics of recurrent basal cell carcinoma after surgical excision in Korean patients. Methods: We analyzed clinical findings and histopathologic subtypes of 21 cases of recurrent basal cell carcinoma after surgical excision among 480 cases diagnosed between January of 1980 and December of 2006 at the Department of Dermatology, Chonbuk National University Hospital. Results: Overall recurrence rate was 4.38%. The average interval between the surgical excision of the primary tumor and recurrence was 40.8 months. The mean age of the patients was 65.1 years old and the ratio of men to women was 1:2. The most frequent location of the tumor recurrence was the nose and the mean size was 1.2 cm. There were no immunocompromised patients with underlying disorders, but two patients had taken corticosteroid for an extended period of time. The most common histological subtype of the primary and the recurrent basal cell carcinoma was nodular type. Six cases of primary basal cell carcinomas of nodular type transformed to aggressive subtype when they recurred. Perineural involvement of the primary basal cell carcinoma was found in 5 cases. Conclusion: This study demonstrates the clinicopathological features of recurrent basal cell carcinoma in the Korean population and we hope this data would be of help to dermatologists when treating Korean patients with basal cell carcinoma.
