Enterprises play an increasingly important role in economic development in each country. Effective businesses will make the economies of countries also become efficient and develop. Enterprises play a role in creating jobs, improving labor productivity, and connecting foreign trade and import-export activities. The study aims to evaluate the factors affecting the profitability of small and medium enterprises in Hanoi by using a study of 210 enterprises in the area as well as advanced econometric regression analysis. The research results show that firm size and human capital have no impact on business performance. However, older firms are likely to have higher firm performance, and conversely, younger firms have lower firm performance. The research also confirms that the growth of businesses often has higher firm performance than low-growth ones. Furthermore, a firm with greater value is also more likely to stimulate business performance than lower its value, and this effect is the largest among the analyzed factors. Finally, the study also has some recommendations for the Vietnamese government to develop small and medium enterprises. Specifically, the government needs to create an open mechanism for the start-up movement and create a favorable financial mechanism for small and medium-sized enterprises to be able to access.

The parking problem is caused by the parking demand. The ratio of parking demand at multi-family housing sites has been increased significantly, therefore several parking problems have occurred. The goal of this study is to investigate the parking demand per housing size of public-sized apartments, and to prepare that with the architectural regulations about parking supply. According to the results of this study, the parking demand of the small size housing unit(exclusive size：60 $m^2$ below) shows 1.09 car per the unit. and that of the medium size housing unit(exclusive size：60 $m^2$ over 85 $m^2$ below) shows 1.34 car per the unit. The parking demand of the small size housing unit was exceeded 56% more than the legal supply limit, and the parking demand of the medium size housing unit was exceeded 34% more. It is means that the level of architectural regulation about parking supply was not enough than the parking demand. So, it needs recon-sideration about the architectural regulations of parking supply.

Wireless Sensor Networks (WSNs) plays an important role in our everyday life. WSN is distributed in all the places. Nowadays WSN devices are developing our world as smart and easy to access and user-friendly. The sensor is connected to all the resources based on the uses of devices and the environment [1]. In WSN, Quality of Service is based on time synchronization and scheduling. Scheduling is important in WSN. The schedule is based on time synchronization. Min-Max data size scheduling is used in this proposed work. It is used to reduce the Delay & Energy. In this proposed work, Two-hop neighboring node is used to reduce energy consumption. Data Scheduling is used to identify the shortest path and transmit the data based on weightage. The data size is identified by three size of measurement Min, Max and Medium. The data transmission is based on time, energy, delivery, etc., the data are sent through the first level shortest path, then the data size medium, the second level shortest path is used to send the data, then the data size is small, it should be sent through the third level shortest path.

Using multivariate GARCH model, we estimate the relationship between the housing sale prices and lease prices in the Korean housing market. In the analysis of relationship between the rate of changes in sale and lease prices, the correlation coefficient of the apartment and detached house is higher than that of the townhouse. By housing type, the correlation coefficient between detached house and townhouse is higher than between apartment and detached house or apartment and townhouse. By housing size, there are no significant different results between the sales price and the rental price. The correlation coefficient between medium and small size is the highest in the apartment housing market, whereas the correlation coefficient between large and medium size is the highest in the detached housing market, resulting from the fact that people may be more interested in medium- and small-sized apartment and large- and medium-sized detached house. In the detached housing market, the correlation coefficient between large-medium size and medium-small size in the rental price is higher than that of sales price. This result implies that the process of the decision making between purchasing and leasing a house might be different.

This paper investigates the effects of public R&D support on medium-sized firms' R&D investment. The paper collects a panel dataset of Korean manufacturing firms' R&D investment and public support, and employs the DID (difference-in-differences) regression for the test of stimulating or crowding-out effect. Empirical analysis examines how the effect of public R&D support differs between small and medium-sized firms and whether firm size and technological capability moderate the effect in the sample of medium-sized firms. Empirical results show that public R&D support tends to generally stimulate private pure R&D investment for both small and medium-sized firms. Comparing the results for small and medium-sized firms, this paper finds that the stimulating effect is relatively larger and more significant for medium-sized firms, while the effect is not significant for small ones. Furthermore, the paper shows that the stimulating effect of public R&D subsidy on private R&D investment is relatively stronger for medium-sized firms with superior technological competence and the effect of tax support is greater for incompetent firms. These results suggest that public R&D policies and R&D programs, differentiated from those for existing small firms, are necessary for medium-sized firms to stimulate private R&D continuously and formulated carefully by considering firm size, technological capability and growth potential.

In this paper have been examained the relation of tssk performance to body size. the variation of venation of males, sex ratio, breeding by forms of worker's pupae and structure by forms of workers's colony to nest size in polymorphism of polydomous red wood ant, Formica rufa truncicola var. yessoensis Forel in Korea. 1. The workers are classified into three forms, in which small form mainly performs itself the task of nursing in the nest and the visit to aphid from the outside of the nest, medium and large form mainly do not only the stinct of prey carrying from the outside of the nest and nest structure, but the task of protecting colony of outside. But the small forms visiting to aphid is not always fixed but seems to be changed with season. 2. The variation forms of venation of males are fourteen, generally, they have various variations of the discoidal. 3. Generally, sex ratio of Formica rufa truncicola var. yessoensis Forel is the same proportion, but it seems that there are some difference according to its characteristic of colony in each nest and polydomous colony structure in its habitat. 4. In summer season the medium form makes a colony in high proportion without any relations with the size of nest but. during hibernation, small form coasists in small nest, medium in medium nest and large in large nest. And so the structure of worker's colony by forms according to their nest size seems to be changed with season.

As the informationized society develops, for companies to be industrially competitive in global competition, innovation of business administration through informationization is a nation-wide task that must be driven. Small-to-mid size companies also tend to recognize the need for informationization and build the information systems, improving their informationization levels. To reduce errors in bringing in and running the information systems and increase efficiency In using them, the need for the standard and guide for informationization in small-to-mid size companies has increased. Accordingly, the national office of small and medium business administration has developed the informationized management system (IMS) certification standard in order to provide a national motive to secure the means for management innovation of small-to-mid size companies and have them recognize informationization as a business strategy. Now, there arises the need for the IMS certification standard, which was developed in early 2000, due to changes in environments of small-and-medium businesses and problems that have been revealed in field applications. In this research, we have examined the current situations of informationization in small-and-medium businesses that were revealed by the 2005 survey on the levels of informationization in small and medium business, have drawn the problems that have occurred in the process of applying the IMS in many small-to-mid size companies, have devised the measures against those problems, and have proposed a new IMS certification standard that reflects those measures. This research has proposed only the direction for development of the IMS certification standard. Future researches should deal with detailed items and criteria for evaluation and continuous improvement of them.

The article 49-2 of Industrial Safety Law requires that all the owners of industrial plants which contains dangerous facilities perform the process safety management. That is, this law requires the owners of industrial plants to take necessary measures to prevent fire, harmful gas leaking, explosion, and other serious accidents that could cause demage and injuries to the employees. So far, domestic chemical plants have tried to invest money and time in safety management. But, such efforts have been made only in chemical plants that were subsidiaries of large business groups. Moreover, since the economic crisis of Korea which is symbolized by the IMF bailout, small and medium size companies could not afford to invest in safety management. Their major concern is to increase productivity and thereby, survive in this crisis. The goal of this research is to develop the process safety management system that can help small and medium size companies to positively secure the process safety management. So, in developing the process safety management system, the financial and practical difficulties of such companies are fully taken into consideration.

In this paper, the security characteristics of healthcare institutions were derived through analysis of previous research, and the characteristics and status of small and medium sized healthcare institutions were surveyed through field surveys of small and medium sized healthcare institutions. The security management evaluation model for small and medium sized healthcare institutions was designed and verified based on the security characteristics of small and medium healthcare institutions. For the design, we compared and analyzed existing security management system and evaluation certification system of healthcare institutions. We also confirmed the proposed security management evaluation model and the degree of sharing. In addition, we conducted validation for the statistical verification of the proposed security management evaluation model for small and medium sized healthcare institutions, and we performed the relative priority analysis through AHP analysis to derive the weight for each item. The result of this study is expected to be used as a standard of security management evaluation model that can be practiced in small and medium sized healthcare institutions.

This study was conducted to evaluate the effects of size grading on growth, feed efficiency and survival of juvenile olive flounder. Juvenile flounder were divided into four groups by initial average size; Small group $(1.3{\pm}0.23g)$, medium group $(3.1{\pm}0.45g)$, large group $(4.9{\pm}0.57g)$ and ungraded group $(3.3{\pm}1.66g)$. Triplicate groups of 100 fish were reared over 8 weeks. In final body weight distribution, frequency of the small size flounder (10 g) was markedly higher in the ungraded group than in the small group. Specific growth rate, feed efficiency and survival in the ungraded group were significantly lower (P<0.05) than those in the pooled data of the othor three graded groups, although feed intake in the ungraded group was significantly higher (P<0.05) than that of the pooled data of the other three graded groups. These results show that the small flounder gained significantly faster growth and higher survival in the absence of the large flounder. Therefore, size grading seems to be an important and necessary operation to improve the growth and survival of juvenile olive flounder (1-5 g).
