Korea companies have been faced with the demand of environmental changes abroad by suffering Economic Crisis at 1997. In fact, these demand that modern firms are in the keen struggles for existence is the essential condition though of the age of Economic Crisis. Coping with these situation. these companies are making desperate efforts, which are reorganization, renovation, improvement, however, the procedure or the result about these efforts of change have to be checked wisely. That is, the firms have to meet requirement that could enhance their values because organization structure that is not efficient to growth of firms produces a quite contrary result. Such phenomenon is applicable to construction firm as well as limited with partial companies. Therefore, before forming a efficient organization structure, comparing and analyzing the strategy or financial statement according to construction firm, this study will try to grasp a characteristic of organization.

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.

This paper examines the relationship between information risk and equity premium in the Korean stock market. We use accruals quality as a proxy of information risk. Accruals quality (AQ) is estimated by Dechow and Dichev (2002) model, and then AQfactor is constructed based on the estimated AQ. Time-series and cross-sectional regression models are used to examine the relationship between information risk and equity premium, reflecting the critics of Core et al. (2008). The result of the paper shows that information risk proxied by accruals quality is not priced in equity premium in the Korean stock market. This result is consistent with Core et al. (2008) for US firms, but different with Francis et al. (2005) for US firms and Gray et al. (2008) for Australia firms. Also, the result shows that AQfactor is closely correlated with firm characteristic variables such as firm size. This implies that the effect of AQ on equity premium is more likely to arise from the pricing error due to firm characteristics rather than from an unknown risk factor.

Environmental problems are becoming hot issues in many countries and the role of the enterprise, which causes environmental contamination, has become one of the most important concerns in business. We consider the factors such as reduce, recycle, reuse, which is effected environment conscious logistics system, and then we are to suggest optimal directions through statistical analysis of effects and causes of the influences of environmental logistics activities on logistics performance. In order to attain this objective we simultaneously execute a literature and actual research considering many manufacturing companies. In this paper we analyze various factors of logistics activities for environment conscious logistics system (ECLS) for economy base construction under resources circulation, and we especially analyze effects and causes of the influences of logistics performance by the operation characteristic of enterprises.

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.
