We derived a length-weight relationship for Calanus sinicus off Busan, Korea in spring to estimate the biomass of the C. sinicus population around Korean waters, and compared it with the previously derived equations. The developmental stages and prosome length of C. sinicus used in the relationship ranged from 1,376-1,540 ㎛ for copepodite 4 (CIV), 1,753-1,971 ㎛ for copepodite 5 (CV), and 2,160-2,283 ㎛ for adults (CVI). Dry weight and carbon content were measured from a total of 26 replicates. Length-weight relationships derived in the present study are as follows: log C = 3.342 log PL - 9.449, log DW = 3.394 log PL -9.219, where C is carbon content (㎍), DW is dry weight (㎍), and PL is prosome length (㎛). When comparing the present regression equation of length-weight for C. sinicus with the previous one, our regression equation showed an average carbon estimate to a given range of mean prosome length. The length-weight relationship of C. sinicus in the present study can be used to better estimate the biomass of the C. sinicus population in the coastal waters of Korea.

Technology Security, especially in knowledge-intensive society, is becoming the most important organizational activity for the long-term success of a firm. However, there is not sufficient empirical research of activities of technology securities and business performance. This is one of the reason why Korean firms are reluctant to invest their resources to the technology security. We have tried to empirically analyze the relationship between a market and technological characteristics, which is one of the important business environmental characteristics and the activities of technology securities of Korean business firm by taking three hypotheses related to this research and investigating 209 Korean firms. According to the statistical research, results of the analyses suggest that the market and technological characteristics have positive impact on the activities of technology securities. Also the activities of technology securities have positive impact on the performance of technology security. More specifically, the results suggest that the relationship between the competitiveness of market and technological excellency and the activities of technology securities is supported statistically. But, the reverse relationship between the easiness of market entrance and the activities of technology securities is supported statistically. Also, there is no moderating effect of firm size between the relationship between a market and technological characteristics and the activities of technology securities. Finally, the relationship between the activities of technology securities and the risk of technology leakage is supported statistically.

Since various R&D projects about technology convergence was conducted by the government of Korea, the lack of liaisons among the projects has been accepted as serious issues related on the duplicated funding. In this article, we propose a research framework to analyze the relationship among national R&D projects about technology convergence. In detail, the projects have been sorted and categorized with the data collected from National Science and Technology Information Service (NTIS) in order to analyze the current state of national R&D projects. The linkages among projects are then established using the results of analysis on national R&D projects. Finally, the relationship maps have been developed. It is expected that the result could be applied to identify the relations among projects and handle problems on the duplicated funding.

Due to the globoal economic effect, Taiwan's small and medium-sized enterprise (SME) is much threatened by China. Since remarkable advances have being made in information technology, taking competition advantage for an enterprise has become a very important issue when facing rigorous global competition. However, the business of the enterprise starts with finding the customers' demands, and ends with fulfilling customers' demands. Therefore, in order to increase competition advantage for SME, the customer management must be effectively strengthened, especially by increasing customer satisfaction and maintaining good relationship with the customer. This is the key for an enterprise leading to success. The purpose of this study is aiming to discussing the relational analysis between customer and SME by viewing the four aspects of customer relationship management (CRM), which are relation marketing, customer service, customer value, and customer satisfaction. Moreover, this research will perform an empirical analysis on CRM for a typical small and medium-sized company so as to grasp its real definition and enterprises' demands. The conclusions will be drawn from our literature survey and practical experience as well as site investigation. Recommendations are evolved from discussing the interaction between customers and enterprises in improving their constructing factors and increasing benefits and values.

Researchers as well as network providers are increasingly interested in understanding how a network user's experience changes in relation to different quality of service (QoS) parameters, with many attempts being made to identify the general relationship between quality of experience (QoE) and QoS. Several relations in different function forms have been proposed. There are instances when this variety of proposed functions potentially results in one problem having completely dissimilar solutions at the same time. The question then is which function form is the one that can better explain this relationship. In this paper, three major existing quantitative relationships between QoE and QoS are investigated. After conducting a comprehensive comparative analysis between them, a new definition of QoE-QoS dependency appears. It then results in identifying a new mutual relationship between QoE and QoS. The newly proposed relationship improves the deficiency of previous QoE-QoS relationships along with solving the problem of diversity of simultaneous solutions for one problem.

With the advance of information technology, it is possible to build the interactive communication channel among relationship participants with low cost, and this channel makes ties between consumers and company by enabling information sharing and exchange. In order to maintain customer relationship, it is necessary to support customer information that includes of-the-customer, for-the-customer, and by-the-customer information. From the three types of customer information, the proper information for the relationship management like the level and type of commitment can be extracted. Customer Information System (CIS), which includes database, communication channel, application program, should be designed to facilitate the customer relationship management. Since lots of investments to information system are required, it is not easy to implement. This paper develops a framework of dynamic customer relationship management and suggests an effective information technology strategy to support that.

Since the introduction of knowledge management systems, many studies have attempted to analyze its performance and identify the success factors. However, few studies have investigated the relationship between KMS technology characteristics and its quality. This paper attempts to categorize KMS technology functions into socialization, externalization, combination and internalization and then find the relationship between these functions and KMS quality. It also attempts to investigate the moderating effect of task characteristics in this relationship. Our research frame is derived from the well known task-technology fit model and the related KMS performance studies. A survey was conducted from 157 KMS users. It is found that both externalization and combination are important for KMS quality and this quality influences the KMS performance. Furthermore, it is confirmed that the task characteristics can moderate between the KMS technology and its quality.

Understanding how the topic evolves is an important and challenging task. A topic usually consists of multiple related events, and the accurate identification of event evolution relationship plays an important role in topic evolution analysis. Existing research has used the traditional vector space model to represent the event, which cannot be used to accurately compute the semantic similarity between events. This has led to poor performance in identifying event evolution relationship. This paper suggests constructing a semantic aspect-based vector space model to represent the event: First, use hierarchical Dirichlet process to mine the semantic aspects. Then, construct a semantic aspect-based vector space model according to these aspects. Finally, represent each event as a point and measure the semantic relatedness between events in the space. According to our evaluation experiments, the performance of our proposed technique is promising and significantly outperforms the baseline methods.

As ICT technology develops rapidly and social and consumer interactions require more knowledge of the technology, the interest for baby boomers' ICT technology acceptance is increasing as they age. However, previous studies have limitations as they lack a systematic and in-depth understanding of this phenomenon in which the emerging elderly population embraces emerging technology. To overcome this limitation, this study carried out a phenomenological study on baby boomers' ICT technology acceptance. In addition, since existing studies have just simply listed variables or proved the relationship between a few variables, this study aimed to find the relationship between variables by analyzing the data obtained through semi-structured interviews. Through this procedure, it was aimed to construct conceptual model which illustrates the relationships between variables so that understanding the phenomenon of baby boomers' acceptance of ICT technology with a holistic view could be possible. The ten variables suggested by Lee & Coughlin (2015) that cover multiple sides of baby boomers' technology acceptance were used. As a result, we found that there is a sequential relationship between these variables and different agents can be related to each variable in sequence. Also, from an ecological perspective, we analyzed baby boomers and their surroundings to find agents involved in this phenomenon.
