This study suggests strategies which can enable to creation of new opportunities of competitive advantages while operating a long lasting and consistent business with major trading partners, based on interorganizational information systems (IOISs) specially established and installed for interorganizational transactions. Nowadays, IOISs based mechanism having been widely expanded as a conventional business infrastructure for the interorganizational transactions and/or exchanges, it is customary difficult to obtain any strongly sound advantage over the competitors who have adopted even the simplest deployment of the IOIS mechanisms. In this connection, this study intends to investigate the interorganizational collaborative activities conducted by under the auspicious of IOISs, focused on the prospect of the exploitation of IOISs rather than the implementation of the IOISs. In this study, we, firstly, suggest the concept of Electronic Collaboration which can be defined by the collaborative activities conducted by IOISs, compared to the ones conducted on off-line. In addition, we suggest the Electronic Collaboration as a multi-dimensional concept, constituted by three sub-constructs, the Electronic Information Sharing (EIS), the Electronic Joint Activity (EJA), and the construction of the Electronic Relational Knowledge Store (ERKS). Secondly, we empirically verify the effects of relational and environmental determinants on the Electronic Collaboration. In this study, the relational determinants relate to the variables created in interorganizational relationship like Trust, Influence, Relational Specific Asset-asset invested for the transaction-, and Continuity of the relationship. On the other hand, the environmental determinants relate to the variables surrounding the relationship which are difficult to control. We consider Product Complexity, Technological Uncertainty, and Market Variability as the domain of the environmental determinants. To test our hypotheses, we conducted both paper-based survey and online-based survey. After refining the data with missing responses, a total of 150 data was used for analysis. The results were as follows : Firstly, it is statistically significant that the Electronic Collaboration is composed of EIS, EJA, and ERKS. In particular, the results imply that the firms are able to accumulate relational knowledge base as well as to exchange information or knowledge, and to conduct joint activities through effort to further expand the Electronic Collaboration. Secondly, we have verified the individual effects of the relational and the environmental determinants on the Electronic Collaboration. Product Complexity has been revealed as the most influential variable affecting the Electronic Collaboration. Next, Interorganizational Trust and Technological Uncertainty, in that order, have been seen to have significant effects on the Electronic Collaboration. In other words, when products or services seem to be difficult to standardize, and the core technologies seem to rapidly change, the need for the Electronic Collaboration increase. In addition, the observation dictates that the interorganizational trust turns out to be a critical variable in building a relationship and in seeking further collaboration. The results, further, illustrate that the environmental determinants are relatively more effective than the relational determinants, which is not consistent with a few prior researches relational determinants emphasized. It is because this study doesn't consider the size of the firm. A few researchers have given an emphasis on the relational determinants like trust and influence, especially from the perspective of small firms in interorganizational relationship. However, in our study, where all the sizes of the firms are contained, electronic collaboration is considerably affected by the environmental determinants.

The traditional image of hydraulic excavator started to change in two ways since 1990. First, post-heavy equipment's visual image was new waves to traditional image of heavy, strong, and wild. They are the negative aspect that excavators have. Another movement of getting rid of its negative image can be found in late-heavy equipment, which was intended to adapt traditional and positive, but off negative images. In 1990s, the design trend is moving from warm/hard to warm/soft, and KOBELCO can be exceptional example that went even further, gone up to cool-soft image. KOBELCO specially aimed 'post- excavator image' strategy, which has been successful. Image of cabin as a human space changed little bit further than outside image. Each company tried to differentiate the design of cabin focusing on its safety. Following paragraphs show specific trend of image change in form, colour, texture, and the composition. Major visual image change in form tries to follow the image of cars and home appliances which are showing the movement from tough and hard image to soft one. Structural change on local image shows the movement from angular edge to edgeless and the movement of cabin's pillar C placed to back of the equipment with gentle inclination. All of these movements are the result of effort to improve traditional excavator's negative image, that top structure is assembled separately, to positive ones. Today's tendency about its color becomes important to apply two different colour styles. Each style has brightness and tone comparison. As an enormous power convey system, it was in common that its brightness comparison was useful because of the alarm of its damage possibility. However, as its colour control and its design have been emphasized gradually, the tone comparison takes a part in an important role, too. As an example, there is an occasion that these comparisons are compromised simultaneously. In the respect of its image creation, its texture treatments make the tendency of being the same as passenger cars. It is caused from its development of the manufacture techniques of from the fabrication method in small business to the press method in big firm. Further, it is also because of its improvement of painting & coating skills. It may prohibit the reflection effect from solar rays. In the point of view of its visual images, it is recognized the prominent tendency that its composition has been gradually decreased. Lots of windows and the frames tends dark-colour as a whole. It is more preferred to have one colour image, but except KOBELCO and HITACHI. As well, there is another high-tendency to improve its standard treatments, especially for its corner and texture treatments.

A wild black-crowned night heron (Nycticorax nycticorax) with dehydration and a non-weight bearing lameness of the left leg was rescued. On physical examination, the left knee was displaced laterally at almost a $90^{\circ}$ angle with firm swelling and crepitus in the area of the coxofemoral joint. Radiographs confirmed cranio-dorsal coxofemoral luxation. A closed reduction attempt failed. The coxofemoral joint luxation was reduced surgically by placement of the femoral neck next to the pelvis with a suture. Ten days after surgery, radiographs and computed tomography showed the femoral neck and head were positioned well within the acetabulum. At 20 days, the bird was using the affected limb normally, and could hunt and forage for food in a rehabilitation housing unit with a small pond. The bird was successfully released into the wild. The placement of the femoral neck adjacent to the pelvis with a suture can be successfully performed for cases of avian coxofemoral joint luxation. Furthermore, this procedure can provide sufficient stabilization of the coxofemoral joint and acceptable limb function.

We explore how stock returns and volatility have been impacted by securities market stimulating and controlling plans during the 1980-2004 period, using return analysis, event study, and BFL tests. First, we examine effectiveness of the stimulating plans for a depressed market and the controlling plans for an overheated market with respect to different firm sizes and industries as well as the whole market. KOSPI, large-sized, finance, and manufacturing company stock prices significantly rise following stimulating plans, implying that the plans are quite effective. Controlling plans also seem effective as stock prices stop rising and tend to decline following the plans. Second, we test whether securities market plans have any further impact with respect to fun sizes and industries in addition to the impact on the entire market. Only large-sized stocks show additional response to stimulating plans, while small-sized, electrical-electronic equipment, distribution, and manufacturing industries are further impacted by controlling plans. Third, the results of BFL tests show that volatility does not change around the announcement dates of stimulating and controlling plans. It appears that securities market plans have no impact on volatility. Only stock returns respond to the plans.

While previous studies and publications all assert a strong correlation between company's business plan and performance, very few have actually conducted practical analyses to support that. This study takes a practical approach in its analysis of Korean small and mid-sized enterprises(SME) with the view to finding an answer to the question. In addition, with the considerations of entrepreneur type and company's development stage, I analyzed the differences of business plan components' effects on performances. I selected business plan's components, which have been suggested only in theory and in concept, through the literature review and preliminary examination. Corporate performances were the recent improvements of ROS, ROA, market share and the number of employees to measure how greatly each is impacted by the components of a business plan. Results show that business plan components have influenced upon the number of employees. The business plan components discriminated superior company group and inferior company group properly. Especially, finance & related system and advertising & distribution factors showed statistically significant classification forecasting power. Technical/Craftsman evaluated the effects of producing & sales and profit & quality factors high and General/Opportunistic evaluated the effects of finance & related system, advertising & distribution, corporate mission factors high. The effect of corporate mission was highest among company development stages. Finance & related system and advertising & distribution factors showed the statistically significant difference in entrepreneur type and company development stages.

Entrepreneurship is an important factor not only for start-ups, but also for scale-up of businesses. In other words, the two aspects of establishment and growth of businesses must be balanced through entrepreneurship. However, it is true that entrepreneurship has been biased toward the former in previous researches and government policies. Here in this research, the causal relationships between the entrepreneurial characteristics of Korean firms and the performance of the company, which is measured by proposal, activity, and business performance are examined as a growth perspective. Based on these relationships, a model describing the operating mechanism of corporate entrepreneurship is derived and policy implications are provided. In conducting research, the hypotheses on the interrelationship of variables are builded using '2016 Entrepreneurship Situation Survey(Corporate)' data from Korea Entrepreneurship Foundation and analyzed by structural equation modeling. In addition, the moderating effect according to the firm size and the mediating effect between entrepreneurship and business performance are analyzed. As a result of this research, the fact that entrepreneurship affects business performance is identified and it is necessary to prioritize corporate vision and strategy for enhancement of entrepreneurship. In particular, necessity of operating system for SMEs is confirmed considering SMEs' entrepreneurship level. The implications of this research are expected to be applied by the government in establishing policy direction to enhance corporate entrepreneurship of SMEs in the future.

Generally, electricity market has monopoly market structure because of need of enormous investment for infrastructure. However, the introduction of competition in network industry as electricity is a tendency of the world with decreasing the effects of economy of scale due to the advancement of technology. Now, electricity industry restructuring is in progress but the competition in electricity retail market is not in force yet in Korea. Whether a effective competition exist or not is very important to policy decision maker who drive restructuring, but there are small numbers of quantitative researches on that. In this study, we estimated the effectiveness of competition in the electricity retail market through switching costs. If switching costs are high, consumers actually can be locked in incumbent firm in spite of introduction of competition. Therefore switching is a critical factor to determine effectiveness of competition and to estimate the size of switching costs quantitatively can proffer the information about whether the competition in the electricity retail market is effective or not in the future. We estimated switching costs using consumer' stated-preference data by conjoint analysis. In according to estimation results, the cost of switching process is not so high, but the relative brand loyalty of an incumbent company is significantly high. And the price is considered as the most important factor choosing an electric service commodity. Based on the empirical results, it is possible to analyze the relationship between suppliers' competitiveness resulted from management efficiency and customers' switching possibilities. The paper therefore provides guidance for suppliers in deciding to enter into retail competition and for policy makers in introducing retail competition. And it has a significance of estimating the switching costs directly.

The purpose of this paper is to explore the relationship between industrial regulations and the R&D activities of firms by analysing the case of manufacturing enterprises in Korea. The sample is gathered from the 2012 Korean Innovation Survey data of Korean Institute of Science & Technology Evaluation and Planning and merged with Korean Regulation Index data of Korean Institute of Public Administration. The Ordinary Least Square (OLS) as well as 2 Stage Least Square (2SLS) regression results show that the impact of the level of the manufacturing field's regulation on firms' R&D activities or inputs may be both positive and negative, depending on the size of the firms. The analysis results suggest that regulatory policy makers need to formulate and implement R&D programs that consider the different effects of industrial regulations on large enterprises or Small and Medium sized Enterprises (SMEs).

Korea's traditional Sokgasans(a artificial rock mountain) are elements of our excellent rock garden culture that have been inherited from Goryeo Era to Chosun Era. This study is to analyze how the culture of Sokgasans in the Goryeo and the Chosun Eras has been has been representated the implications and inherited in terms of historical aspects. Korea's traditional Sokgasans, which were created in the Goryeo Era by imitating the landscape of mountain ranges, created a small artificial mountain made of oddly shaped stones, imitating a real mountain. People in those days would reproduce mountain landscapes through a miniaturization technique, enjoying the pleasure of deep mountains and valleys as they lay on their gardens at home while having an aesthetic experience of the landscape that supported their emotional stability and healing. The inner side of these Sokgasan was intended to represent the world of the Taoist hermit with miraculous powers in terms of utopia, expressing 5 Ak mountains(Song Shan, Taishan, Huashan, Heng Shan and Hyeong Shan) where the mountain of 3 Gods(Youngju, Bongrae and Bangjang) wishing for 'No aging and living long' and idea of the Taoist hermit with miraculous powers are concentrated beyond the beauty of form in the landscape itself. In addition, people could refine their minds by practicing the Confucianist lesson of loving the mountain and water by watching the Sokgasan and imitating 'Famous mountains and lakes" from China and they had been changed and advanced embracing various implications in inner side of Sokgasans. Korea's traditional Sokgasans not only made it possible for people to experience aesthetic landscapes as a practical element of the scenery but also had deep symbolic implications that go beyond their formal beauty and were sublimated as an ideational space of unlimited imagination.

Prior bankruptcy studies have established that bankrupt firm's pre-filing financial ratios are different from those of healthy firms or of randomly selected going concerns. However, they may not be sufficiently different from the financial ratios of other firms in financial distress to allow the development of a ratio-based model that predicts bankruptcy with reasonable accuracy. As the result, in the multiple discriminant model, independent variables divided firms into bankrupt firms and healthy firms are retained earnings to total asset, receivable turnover, net income to sales, financial expenses, inventory turnover, owner's equity to total asset, cash flow to current liability, and current asset to current liability. Moreover four variables Retained earnings to total asset, net income to sales, total asset turnover, owner's equity to total asset indicate that these valuables classify bankrupt firms and distress firms. On the other hand, Owner's Equity to borrowed capital, Ordinary income to Net Sales, Operating Income to Total Asset, Total Asset Turnover and Inventory Turnover are selected to predict bankruptcy possibility in the Logistic regression model.
