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.

최근 증가하고 있는 기술유출 사고로 인하여 기업의 금전적 손실, 기업 이미지 훼손, 거래처 단절 등 기업의 막대한 손실이 발생하면서 기술보호에 대한 기업들의 노력정도와 경영층의 기술보호 투자에 대한 관심이 늘고 있으나 기술보호 투자에 대한 성과 특히, 경제적 또는 기술적 성과 분석에 관한 연구가 미흡하여 기술보호에 따른 효과에 대해 명확히 설명하는데 어려움이 있어 기술보호에 대한 투자를 확대하는데 여전히 한계가 있는 실정이다. 이에 따라 본 연구는 기업의 시장특성 및 기술특성이 기술보호 노력정도에 미치는 영향과 기업의 기술보호활동이 기업의 경제적 기술적 성과에 미치는 영향에 관한 연구를 수행하였다. 분석 결과, 시장의 경쟁강도, 시장진입 수월성, 기술우수성이 기술보호 노력정도에 미치는 영향을 살펴본 결과 시장의 경쟁강도와 기술우수성은 기술보호 노력정도에 정의 유의한 영향을 보여주었다. 반면, 시장진입 수월성이 높아지면 기업은 기술보호 노력을 추진하지 않는 것으로 나타났다. 또한 기업규모가 크거나 작은 것과는 관계없이 기술보호 노력정도에 미치는 영향력은 크게 달라지지 않는 것으로 나타났으며 기술보호 노력정도가 기술유출위험도를 낮추고 있는 것으로 나타났다.

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.

최근 정보기술의 발달로 저비용의 대화 채널 구축이 용이해짐에 따라 최종소비자와 기업간의 정보 교환 및 공유가 활발해지고 단속적거래 보다는 지속적인 거래를 통한 관계적 결속이 늘어 가고 있다. 지속적 교환관계에서는 거래정보와 비거래 정보의 흐름이 발생하는데, 정보기술을 이용하여 고객의 정보, 고객을 위한 정보, 고객에 의한 정보등을 관리함으로써 관계관리에 있어 핵심적 역량을 창출할 수 있다. 본 연구에서는 소비자와 기업간의 관계적 결속 생성에 대한 이론적 배경을 토대로 정보 흐름의 관점에서 동적인 관계관리의 개념적 틀을 제시하였다. 또한 이를 지원하기 위한 고객 정보시스템 아키텍처를 설계하고 국내 기업사례에 실제로 적용해 보았다.

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.
