우리나라 기업들은 허근 경제 위기를 겪으면서 대외적으로 커다란 환경변화의 요구에 직면해 왔다. 사실 이러한 변화요구는 굳이 경제 위기가 아니라 할지라도 치열한 생존경쟁에 있는 현대의 기업들에게 있어서는 필수요소라 할 수 있다. 이에 대응하여 기업들은 구조조정, 혁신, 조직개선 등의 이름으로 다양한 변화노력을 기울이고 있지만 이와 같은 변화의 노력에 대해 그 진행과정이나 결과에 대해서는 현명한 검토가 있어야 할 것이다. 즉, 기업의 성장에 도움이 되지 않는 조직 구조는 오히려 기업에 역효과로 작용하게 되므로 기업은 가치를 높일 수 있는 조직구조를 갖추어야 한다. 이차 같은 현상은 일부 기업에게만 국한되는 것이 아니라 건설기업에도 마찬가지로 적용됨 수 있다. 따라서 본 연구에서는 효율적인 조직구조를 갖추기에 앞서서 건설 기업의 조직구조를 전략 및 경영성과와 비교${\cdot}$분석하여 조직의 특성을 파악하고자 한다.

The purpose of this study is to extract the characteristic cost through the time series analysis of each cost from 2003 to 2014, and to grasp the performance and relevance of the enterprise. Therefore, in this section, we analyzed the time-series analysis of selling, administrative, and non-operating expenses as described above. First, depreciation cost, advertising cost, transportation cost, research cost, current research cost, and ordinary development cost were extracted as the variables of interest to be verified in the empirical analysis. However, in the analysis of non-operating expenses, we could not extract the specific cost, but we could grasp the time-series flow of cost data before and after two epochs such as financial crisis and introduction of IFRS obligation. The results of this study show that sales management costs have a positive (+) effect on firm value. Empirical analysis confirms that management is trying to increase or decrease the cost This can be confirmed by the empirical results of this paper. At present, general enterprise accounting is done through ERP system. However, since the ERP system does not have an analysis system for each sales and management cost, the current system has difficulty in knowing the budget item for each cost each time the expenditure resolution for each cost item is made, It is a reality that the expenditure plan must be managed separately and it is inconvenient to keep it. However, if this practical difficulty is solved by the cost analysis system such as sales management cost, the present accounting information system will be further developed. Furthermore, the management will increase the profit item It is thought that coordination actions can also be prevented in advance.

본 연구에서는 발생액의 질(AQ)을 정보위험의 대용치로 하여 정보위험이 기존의 자산가격결정 모형에서 고려하지 못했던 새로운 위험요인인가에 대해 실증 분석하였다. 정보위험의 대용변수인 AQ는 확장된 Dechow and Dichev(2002)의 모형을 이용하여 측정하였고, 이를 이용하여 정보위험과 주식수익률 프리미엄 간의 관계를 검증하였다. Fama-French의 3요인 모형에 정보위험요인인 AQfactor를 포함한 모형과 이에 기초한 횡단면 모형을 통해 분석한 결과, 한국자본시장에서 AQfactor에 대한 베타위험은 주식수익률 프리미엄과 유의적인 관계를 갖지 못하며, 그 관계는 포트폴리오 특성에 따라 다르며 일관적이지 못하다. 이는 미국과 호주에 대한 Francis et al.(2005), Gray et al.(2009) 의 연구결과와는 대비되는 것으로 한국자본시장에서 AQ로 측정된 정보위험이 주식수익률을 결정하는 가격결정요인으로 작용하지 못함을 나타내는 것이다. AQ를 기업의 기본여건과 관련된 부분과 경영자의 재량과 관련된 부분으로 분해한 경우 역시 유사한 결과를 보여준다. 한편, AQfactor는 기업규모와 밀접한 상관관계를 가져 한국자본시장에서 AQ로 측정된 정보위험과 주식수익률 프리미엄 간의 관계가 기업특성변수와 관련된 현상일 가능성을 시사한다.

This study focuses on the fact that the Korean traditional design application appears as one of the trends for a planning technique to express an apartment as a healthy, clean and environment-friendly dwelling recently. Focusing on this, this study tries to apply the characteristic of Han-Ok to an apartment unit plan more compositively beyond the fragmentary design application of existing preceding researches. To do this, the space organization, residential space and housing design elements of Han-Ok are deducted through preceding researches and case studies and proposes a plan by applying this to the apartment plan with a floor plan of about $132m^2$(40 pyeong). The apartment unit plan containing the characteristic of Han-Ok proposed in this study is planned based on the floor plan of about $132m^2$(40 pyeong) which is distributed the most in the city of Seoul. It has an advantage in terms that it can be individually applied not only when a construction firm progresses business anew carrying the banner for a Korean-style apartment but also an existing residents can apply through remodelling. Meanwhile, it has a limit that the diversified space sense and the advantage of an airy Han-Ok cannot be applied to many parts of the design due to the characteristic of an apartment of diverse height change. If a measure to secure constructability and economic feasibility while reflecting diverse differences of floor-level of an apartment can be prepared in follow-up researches, much more various advantages of Han-Ok can be put into the apartment design.

The solid-iron rotor induction motor is the squirral cage type induction motor with its rotor core consisting of solid iron in stead of a laminated core. The specific feature of this motor are that its structure is simple and firm, and therefore provides the great convenience in its operation and that its starting characteristic are excellent. this study is aimedto derive the equation for theroretical evaluation of the speed-torque characteristics of the motor by use of maxwell's equation. Through the series of test on the speed-torque characteristics of this motor which is experimentally constructed, we have proved the feasibility of the equaiton which is derived theoretically to calculate the torque of the motor. In addition we have obtained its general charastristics experimentally.

Recently, we experienced a case of rare neurilemmoma originated from intercostal nerve [9th] in the right chest wall in a 25 year old male officer. The tumor was incidentally found in the routine chest X ray, where the round well circumscribed mass tumor the ninth rib with notching and sclerotic margin, suggesting slowly growing benign benign of chest wall was revealed and the tumor mass was easily extirpated in the exploratory thoracotomy, with uneventful recovery. Grossly, the tumor was firm, partly soft and well circumscribed, measuring 4.5X3.0X 3.0 cm with yellowish smooth outer surface, attached with intercostal nerve trunk. Cut surface exhibits partly grayish white and largely hemorrhagic areas. Microscopically, the characteristic palisading arrangement of schwann cells and Verocay bodies are seen but dominant features are cystic degeneration and hemorrhage with organization and fibrosis. The sheath of intercostal nerve and capsule of neurilemmoma were con joined. There is no evidence of malignancy. The tumor was confirmed as neurilemmoma of intercostal nerve, Antony type B.

This study examined variations in postmortem meat quality characteristics and consumer sensory evaluations of different pork quality classes in fresh and cooked meat. Pale, soft, and exudative (PSE) meat had the highest drip loss, lightness, and the lowest $pH_{24\;hr}$ whereas dark, firm, and dry (DFD) meat showed the opposite results. When the fresh meat was evaluated by consumer panelists, they could only distinguish the PSE class of meat and it scored lowest in overall acceptability. However, the panelists did not consider cooked PSE or DFD pork to be unacceptable overall, indicating that consumers cannot distinguish the quality of cooked pork.

A male Blue-fronted amazon parrot suddenly died after having a history of depression, anorexia and emaciation. At necropsy, numerous well-demarcated yellow to white firm nodules were scattered throughout the left caudal lung lobes and adjacent air sac. Histologically, the wall of air sac was significantly thickened due to necrosis and infiltration of large numbers of fungi and degenerated heterophils. Multifocal necrotizing granulomatous lesions with numerous fungal hypae as well as vasculitis and thrombosis were found in tl1e lung. The fungi had conidiophore, vesicle, phialides and conidia which were characteristic of Aspergillus sp. This is tl1e first report of mycotic air sacculitis and pneumonitis caused by Aspergillus in a parrot in Korea.

The present study has an objetive to define the characteristic of the Porous Concrete to be used in the resistant layers of the pavement. Up to the moment there is no material which is capable which is capable of satisfying the mechanical resistances and drainability, two characterstics which interves, and a detailled study has been carried out on the same order to obtain the porous concrete of this study. such as: Mode and time of compaction. type of cement, water/cement ratio, maxium size of aggregates, sieve test. incorporation of some additives and additions etc., among them emphasizing the use of a method of compaction vibro-compression in the laboratory with which an optimum compacting was reached, and can be obtanied on the site with a spreader rated with double tamper. With this porous concrete for this study whose dominating characteristics is the drainability jointly with a high mechanical resistance. a safe and silence firm is obtained, with can be a great diffusion in the near future, for its application on the pavements. Based on these works carried out, there was the first experience in the world of field application with 25cm of resistance layer of Porous Concrete Pavement in Salamanca, Spain.
