  • Objectives The purpose of this study is to systematically review the effects of Neuromuscular Electrical Stimulation treatment on muscle wasting in cancer patients. Methods Randomized controlled trials (RCTs) were searched from seven online databases (PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure, Oriental Medicine Advanced Searching Integrated System, Korean studies Information Service System, Research Information Sharing Service. The selected RCTs were evaluated for methodological quality through the Cochrane RoB. Results A total of 126 articles were identified, and 4 randomized controlled trials were selected for systematic review. In one study, it was found that there were statistically significant improvements in the Health-Related Quality of Life (FACTH&N total score, p<0.001). Additionally, significant effects were observed in measurements that represented the size of the quadriceps muscle (cross-sectional area of Vastus lateralis and Rectus femoris, p=0.004), maximum muscle strength, the twitch response of resistance muscles, and voluntary activation (p<0.001). However, no significant differences were observed between the intervention and control groups in terms of quadriceps muscle strength in two other studies (p>0.05). Lastly, while one study showed no significant differences in muscle fiber characteristics between the two groups, it did report significant improvements in measurements related to mitochondria within muscle tissue and muscle strength in the intervention group (p<0.05). Conclusions Neuromuscular electrical stimulation can be a method used to improve muscle strength in muscle wasting of cancer patients, but it is difficult to see its effects as significant compared to other treatments.

  • 독자적인 부가가치를 만드는 산업화한 디자인이 디지털혁명을 만나면서, 마치 eBiz가 온라인과 연관된 사업으로 등장한 것처럼, 'e디자인'이라는 새로운 디자인 영역이 등장하였다. e디자인분야는 비인간적인 컴퓨터기술을 통해 인간의 감성을 충족시켜야 하는 만큼 별도의 디자인 프로세스 및 관리방법론이 필요하다. 본 연구에서는 e비즈니스를 중심으로 e디자인 프로세스 및 템플릿을 기반으로 한 e디자인 플랫폼을 개발을 한다. 템플릿이란 정형화된 형식을 가진 도큐먼트로 때로는 양식이라 일컬으며 e디자인플랫폼이란 e디자인을 하기 위한 기반이며 인프라인 것이다. 본 연구의 방법은 현장조사, 사례조사, 문헌조사와 각 조사의 분석에 의해서 진행이 되었다. 현 e디자인플랫폼의 문제점을 심층 분석을 통해 파악하였으며, 특히 문서화 지 않음으로 해서 커뮤니케이션의 오류를 많이 일으키며 정보공유, DB저장을 할 마땅한 공용의 공통된 플랫폼이 없어 정보 및 지식공유가 어렵다는 것을 알게 되었다. 특히 문서제작을 꺼려하는 디자이너에게는 양식화된 서류의 샘플이 필요하다는 것을 발견하였다. 프로젝트진행에서 e디자인 프로세스가 크게 6단계로 초기화, 개념화, 시각화, 구현화, 검증화, 유지보수 단계로 이루어진다. 모듈화, 동시다발적, 피드백, 협동작업의 특징을 가진 e디자인 프로젝트의 프로세스의 시각화하는 기법을 단계별, 역할별, 입출력별, 정보형식, 의사결정의 영향요소를 고려하여 범례를 만들었다. 프로젝트에 효과적으로 이용될 수 있는 템플릿의 제작을 위해서 정보의 인덱스, 정보의 프레임워크, 기업의 아이덴터티 요소, 템플릿의 저장위치 둥을 고려하였으며 각 프로세스 단계별로 프로세스 상에 매핑하였다. 프로세스에서 어떠한 산출물이 만들어져서 DB화되는지 알 수 있게 되었으며 템플릿을 만들어 디자이너에게 제공하므로써 양식화된 템플릿을 기반으로 조직 내 오가는 문서를 쉽게 만들 수 있게 되었다. 기업 자체의 사내/사외 프로젝트의 체계적인 관리가 가능해지고, 데이터베이스화한 자료를 통해 사내 지식이 축적되며 커뮤니케이션이 원할 하게 되고 진행과정을 중간 점검할 수 있는 체크리스트처럼 사용될 수 있어 프로젝트마다 반복해 온 시행착오를 줄일 수 있게 된다. 그리하여 결론적으로 시각화된 프로세스와 템플릿 제작이 e디자인프로젝트를 효과적으로 수행할 수 있는 기반이 되는 e디자인플랫폼을 개선한다. 산학연구로 이루어진 본 연구를 통해 디자인, IT 업계를 중심으로 한 중소기업이나 디자인팀에 폭넓게 활용될 수 있는 e디자인 플랫폼을 제안하였다. 그리하여 자체 프로세스를 개발하지 못한 다수의 소규모 디자인 회사로선 자기 회사업무에 응용할 수 있는 상세한 프로세스 방법론을 접할 수 있고, 오픈 된 표준 e디자인의 프로세스가 있을 경우 자사의 프로세스와 비교할 수 있는 기준으로 사용되었으면 한다.

  • Recently, as the information communication technology develops, the discussion regarding the ubiquitous environment is occurring in diverse perspectives. Ubiquitous environment is an environment that could transfer data through networks regardless of the physical space, virtual space, time or location. In order to realize the ubiquitous environment, the Pervasive Sensing technology that enables the recognition of users' data without the border between physical and virtual space is required. In addition, the latest and diversified technologies such as Context-Awareness technology are necessary to construct the context around the user by sharing the data accessed through the Pervasive Sensing technology and linkage technology that is to prevent information loss through the wired, wireless networking and database. Especially, Pervasive Sensing technology is taken as an essential technology that enables user oriented services by recognizing the needs of the users even before the users inquire. There are lots of characteristics of ubiquitous environment through the technologies mentioned above such as ubiquity, abundance of data, mutuality, high information density, individualization and customization. Among them, information density directs the accessible amount and quality of the information and it is stored in bulk with ensured quality through Pervasive Sensing technology. Using this, in the companies, the personalized contents(or information) providing became possible for a target customer. Most of all, there are an increasing number of researches with respect to recommender systems that provide what customers need even when the customers do not explicitly ask something for their needs. Recommender systems are well renowned for its affirmative effect that enlarges the selling opportunities and reduces the searching cost of customers since it finds and provides information according to the customers' traits and preference in advance, in a commerce environment. Recommender systems have proved its usability through several methodologies and experiments conducted upon many different fields from the mid-1990s. Most of the researches related with the recommender systems until now take the products or information of internet or mobile context as its object, but there is not enough research concerned with recommending adequate store to customers in a ubiquitous environment. It is possible to track customers' behaviors in a ubiquitous environment, the same way it is implemented in an online market space even when customers are purchasing in an offline marketplace. Unlike existing internet space, in ubiquitous environment, the interest toward the stores is increasing that provides information according to the traffic line of the customers. In other words, the same product can be purchased in several different stores and the preferred store can be different from the customers by personal preference such as traffic line between stores, location, atmosphere, quality, and price. Krulwich(1997) has developed Lifestyle Finder which recommends a product and a store by using the demographical information and purchasing information generated in the internet commerce. Also, Fano(1998) has created a Shopper's Eye which is an information proving system. The information regarding the closest store from the customers' present location is shown when the customer has sent a to-buy list, Sadeh(2003) developed MyCampus that recommends appropriate information and a store in accordance with the schedule saved in a customers' mobile. Moreover, Keegan and O'Hare(2004) came up with EasiShop that provides the suitable tore information including price, after service, and accessibility after analyzing the to-buy list and the current location of customers. However, Krulwich(1997) does not indicate the characteristics of physical space based on the online commerce context and Keegan and O'Hare(2004) only provides information about store related to a product, while Fano(1998) does not fully consider the relationship between the preference toward the stores and the store itself. The most recent research by Sedah(2003), experimented on campus by suggesting recommender systems that reflect situation and preference information besides the characteristics of the physical space. Yet, there is a potential problem since the researches are based on location and preference information of customers which is connected to the invasion of privacy. The primary beginning point of controversy is an invasion of privacy and individual information in a ubiquitous environment according to researches conducted by Al-Muhtadi(2002), Beresford and Stajano(2003), and Ren(2006). Additionally, individuals want to be left anonymous to protect their own personal information, mentioned in Srivastava(2000). Therefore, in this paper, we suggest a methodology to recommend stores in U-market on the basis of ubiquitous environment not using personal information in order to protect individual information and privacy. The main idea behind our suggested methodology is based on Feature Matrices model (FM model, Shahabi and Banaei-Kashani, 2003) that uses clusters of customers' similar transaction data, which is similar to the Collaborative Filtering. However unlike Collaborative Filtering, this methodology overcomes the problems of personal information and privacy since it is not aware of the customer, exactly who they are, The methodology is compared with single trait model(vector model) such as visitor logs, while looking at the actual improvements of the recommendation when the context information is used. It is not easy to find real U-market data, so we experimented with factual data from a real department store with context information. The recommendation procedure of U-market proposed in this paper is divided into four major phases. First phase is collecting and preprocessing data for analysis of shopping patterns of customers. The traits of shopping patterns are expressed as feature matrices of N dimension. On second phase, the similar shopping patterns are grouped into clusters and the representative pattern of each cluster is derived. The distance between shopping patterns is calculated by Projected Pure Euclidean Distance (Shahabi and Banaei-Kashani, 2003). Third phase finds a representative pattern that is similar to a target customer, and at the same time, the shopping information of the customer is traced and saved dynamically. Fourth, the next store is recommended based on the physical distance between stores of representative patterns and the present location of target customer. In this research, we have evaluated the accuracy of recommendation method based on a factual data derived from a department store. There are technological difficulties of tracking on a real-time basis so we extracted purchasing related information and we added on context information on each transaction. As a result, recommendation based on FM model that applies purchasing and context information is more stable and accurate compared to that of vector model. Additionally, we could find more precise recommendation result as more shopping information is accumulated. Realistically, because of the limitation of ubiquitous environment realization, we were not able to reflect on all different kinds of context but more explicit analysis is expected to be attainable in the future after practical system is embodied.

  • As mobile devices that can be connected to the Internet have spread and networking has become possible whenever/wherever, the Internet has become central in the dissemination and consumption of news. Accordingly, the ways news is gathered, disseminated, and consumed have changed greatly. In the traditional news media such as magazines and newspapers, expert editors determined what events were worthy of deploying their staffs or freelancers to cover and what stories from newswires or other sources would be printed. Furthermore, they determined how these stories would be displayed in their publications in terms of page placement, space allocation, type sizes, photographs, and other graphic elements. In turn, readers-news consumers-judged the importance of news not only by its subject and content, but also through subsidiary information such as its location and how it was displayed. Their judgments reflected their acceptance of an assumption that these expert editors had the knowledge and ability not only to serve as gatekeepers in determining what news was valuable and important but also how to rank its value and importance. As such, news assembled, dispensed, and consumed in this manner can be said to be expert-based recommended news. However, in the era of Internet news, the role of expert editors as gatekeepers has been greatly diminished. Many Internet news sites offer a huge volume of news on diverse topics from many media companies, thereby eliminating in many cases the gatekeeper role of expert editors. One result has been to turn news users from passive receptacles into activists who search for news that reflects their interests or tastes. To solve the problem of an overload of information and enhance the efficiency of news users' searches, Internet news sites have introduced numerous recommendation techniques. Recommendations based on popularity constitute one of the most frequently used of these techniques. This popularity-based approach shows a list of those news items that have been read and shared by many people, based on users' behavior such as clicks, evaluations, and sharing. "most-viewed list," "most-replied list," and "real-time issue" found on news sites belong to this system. Given that collective intelligence serves as the premise of these popularity-based recommendations, popularity-based news recommendations would be considered highly important because stories that have been read and shared by many people are presumably more likely to be better than those preferred by only a few people. However, these recommendations may reflect a popularity bias because stories judged likely to be more popular have been placed where they will be most noticeable. As a result, such stories are more likely to be continuously exposed and included in popularity-based recommended news lists. Popular news stories cannot be said to be necessarily those that are most important to readers. Given that many people use popularity-based recommended news and that the popularity-based recommendation approach greatly affects patterns of news use, a review of whether popularity-based news recommendations actually reflect important news can be said to be an indispensable procedure. Therefore, in this study, popularity-based news recommendations of an Internet news portal was compared with top placements of news in printed newspapers, and news users' judgments of which stories were personally and socially important were analyzed. The study was conducted in two stages. In the first stage, content analyses were used to compare the content of the popularity-based news recommendations of an Internet news site with those of the expert-based news recommendations of printed newspapers. Five days of news stories were collected. "most-viewed list" of the Naver portal site were used as the popularity-based recommendations; the expert-based recommendations were represented by the top pieces of news from five major daily newspapers-the Chosun Ilbo, the JoongAng Ilbo, the Dong-A Daily News, the Hankyoreh Shinmun, and the Kyunghyang Shinmun. In the second stage, along with the news stories collected in the first stage, some Internet news stories and some news stories from printed newspapers that the Internet and the newspapers did not have in common were randomly extracted and used in online questionnaire surveys that asked the importance of these selected news stories. According to our analysis, only 10.81% of the popularity-based news recommendations were similar in content with the expert-based news judgments. Therefore, the content of popularity-based news recommendations appears to be quite different from the content of expert-based recommendations. The differences in importance between these two groups of news stories were analyzed, and the results indicated that whereas the two groups did not differ significantly in their recommendations of stories of personal importance, the expert-based recommendations ranked higher in social importance. This study has importance for theory in its examination of popularity-based news recommendations from the two theoretical viewpoints of collective intelligence and popularity bias and by its use of both qualitative (content analysis) and quantitative methods (questionnaires). It also sheds light on the differences in the role of media channels that fulfill an agenda-setting function and Internet news sites that treat news from the viewpoint of markets.

  • The purpose of this study is to empirically analyze how social comparative learning of forum participants affects learning effects with an emphasis on participants' characteristics. As today's society is changing at a fast pace, the desire for new knowledge and information has grown accordingly. To quench this thirst for knowledge and information, seminars, symposiums, conferences, forums, conventions, exhibitions, and more are taking place as part of knowledge sharing events across the world. Also, the increased need for knowledge and information exchange has led the development and growth of the convention industry and Meetings, Incentives, Conferences, and Events (Exhibitions)(MICE) industry. Especially, forum is a type of event which invites professionals and specialists to discuss diverse topics and share their knowledge and experience with the audience. The participants utilize it as an opportunity to get close to information providers and enjoy the pleasure of knowledge exchange. However, there have been few empirical analyses on who the participants are, why they attend forum, how they pick up and learn new information and knowledge, and what kinds of learning effects they achieve after the event. This paper is to analyze how social comparative learning of the forum's participants influences learning effects based on Albert Bandura's Social Learning Theory (1977, 1997, 1982. 2001) and Leon Festinger's Social Comparative Theory (1950, 1954). By dividing the participants into two groups, one with high level of self-efficacy and the other with low level of self-efficacy, we have examined the differences in learning effects between the two groups using them as moderating variables. This study was conducted in 'MBN Y Forum 2016,' which is one of the most representative knowledge exchange forums of South Korea. An online survey was distributed out and, 1,307(39.2%) out of the total participants of 3,338 have completed the survey. The survey included questions about whether the participants have gained positive or negative motivations by comparing themselves to the speakers (upward comparison learning) and other participants (lateral comparison learning). The results have shown the quality of messages that the speakers are presenting as knowledge providers is the most significant factor that acts on learning effects. Particularly, the participants had higher levels of self-efficacy and self-esteem than average people. They had a clear goal to learn from the speakers (upward comparison) and received positive motivations from them. In other words, no negative learning effects had been found. This presents a managerial implication that having a qualified speaker is necessary for a forum to be successful. On the other hand, the results from the comparison with the other participants (lateral comparison) were different. The participants were likely to compare themselves to the other participants through observational learning. They could compare listening attitudes, language skills, or capabilities to ask a question. The results have showed the participants received positive motivations from the lateral group but at the same time were jealous of abilities of the others. When the quality of a question by a participant is not good enough, it can have a negative influence on the participants' learning effects. The first group with high levels of self-efficacy and self-esteem had no correlation to negative learning effects from the speakers. They rather had a strong desire to learn from the speakers. On the contrary, the participants perceived the lateral group as a learning subset and competitor. The second group with low levels of self-efficacy and self-esteem saw the quasi-group as a rival. This presents that the individual learning effects can be different depending on the participants' characteristics.

  • The advent of the Internet and related Web technologies has created an easily accessible link between a firm and its customers, and has provided opportunities to a firm to use information technology to support supplementary after-sale services associated with a product or service. It has been widely recognized that supplementary services are an important source of customer value and of competitive advantage as the characteristics of the product itself. Many of these supplementary services are information-based and need not be co-located with the product, so more and more companies are delivering these services electronically. Net-based customer service, which is defined as an Internet-based computerized information system that delivers services to a customer, therefore, is the core infrastructure for supplementary service provision. The importance of net-based customer service in delivering supplementary after-sale services associated with product has been well documented. The strategic advantages of well-implemented net-based customer service are enhanced customer loyalty and higher lock-in of customers, and a resulting reduction in competition and the consequent increase in profits. However, not all customers utilize such net-based customer service. The digital divide is the phenomenon in our society that captures the observation that not all customers have equal access to computers. Socioeconomic factors such as race, gender, and education level are strongly related to Internet accessibility and ability to use. This is due to the differences in the ability to bear the cost of a computer, and the differences in self-efficacy in the use of a technology, among other reasons. This concept, applied to e-commerce, has been called the "e-commerce divide." High Internet penetration is not eradicating the digital divide and e-commerce divide as one would hope. Besides, to accommodate personalized support, a customer must often provide personal information to the firm. This personal information includes not only name and address, but also preferences information and perhaps valuation information. However, many recent studies show that consumers may not be willing to share information about themselves due to concerns about privacy online. Due to the e-commerce divide, and due to privacy and security concerns of the customer for sharing personal information with firms, limited numbers of customers adopt net-based customer service. The limited level of customer adoption of net-based customer service affects the firm profits and the customers' welfare. We use a game-theoretic model in which we model the net-based customer service system as a mechanism to enhance customers' loyalty. We model a market entry scenario where a firm (the incumbent) uses the net-based customer service system in inducing loyalty in its customer base. The firm sells one product through the traditional retailing channels and at a price set for these channels. Another firm (the entrant) enters the market, and having observed the price of the incumbent firm (and after deducing the loyalty levels in the customer base), chooses its price. The profits of the firms and the surplus of the two customers segments (the segment that utilizes net-based customer service and the segment that does not) are analyzed in the Stackelberg leader-follower model of competition between the firms. We find that an increase in adoption of net-based customer service by the customer base is not always desirable for firms. With low effectiveness in enhancing customer loyalty, firms prefer a high level of customer adoption of net-based customer service, because an increase in adoption rate decreases competition and increases profits. A firm in an industry where net-based customer service is highly effective loyalty mechanism, on the other hand, prefers a low level of adoption by customers.

  • 기업들이 정보공유를 통한 협업과 신속한 의사결정을 위해 기업용 SNS를 시도하고 있다. 본 연구에서는 기업용 SNS 이용수준이 업무성과에 미치는 영향에 있어서 커뮤니케이션 수준의 매개효과를 검증하였다. 조직 커뮤니케이션은 경쟁우위 확보의 핵심 요소가 되기 때문에 그 선행요인을 규명하는 것이 매우 중요하기 때문이다. 다음으로 본 연구에서는 권력거리를 바탕으로 기업용 SNS 수준이 커뮤니케이션 수준에 미치는 영향에 대한 국적 조절효과를 검증하였다. 기업용 SNS를 도입하기 이전에 오프라인 조직문화를 정보기술에 적합하도록 변화시키거나 권력거리가 낮은 조직에서 기업용 SNS를 도입하는 것이 유효하다고 가정했기 때문이다. 이를 검증하기 위해 본 연구에서는 한국과 중국에서 기업용 SNS를 도입하여 운영하고 있는 기업의 구성원을 대상으로 한국 81부, 중국 81부의 설문 데이터를 회수하여 SPSS 다중회귀분석을 수행하였다. 연구모형 검증결과, 기업용 SNS는 업무성과에 직·간접 영향을 미치는 것으로 나타났다. 첫째, 기업용 SNS는 조직 구성원들이 정보를 신속하게 공유하고 피드백을 빠르게 주고받도록 지원함으로써 오류를 줄이거나 예방하여 업무성과 향상에 직접적인 영향을 미치는 것으로 나타났다. 둘째, 커뮤니케이션 수준은 기업용 SNS가 업무성과에 미치는 영향을 매개하는 것으로 나타났다. 즉, 기업용 SNS는 면대면 커뮤니케이션을 온라인으로 수행하도록 함으로써 소통의 불안감이나 스트레스를 낮춰 커뮤니케이션을 원활하게 하고, 협조적이며 창의적인 조직 분위기를 조성하는데 기여함으로써 업무성과 향상에 간접적인 영향을 미치는 것으로 나타났다. 셋째, 기업용 SNS 이용수준의 커뮤니케이션 수준에 대한 국적 조절효과 가설은 검증결과 가설과 반대로 한국이 중국보다 더 높게 나타났다. 이것은 기업용 SNS가 오프라인의 경직된 소통의 우회통로로 사용되어 나타난 결과라 해석된다. 즉, 오프라인 환경에서 높은 권력거리로 인해 상하 간 커뮤니케이션이 경직되고 폐쇄적으로 흐르는 것이 비대면 기업용 SNS를 이용함으로써 대면소통의 불안감이나 스트레스가 감소하여 상하 간 커뮤니케이션이 보다 원활하게 흐르게 된 것이라 해석된다. 본 연구는 기업용 SNS 이용수준이 커뮤니케이션 수준을 향상시켜 업무성과를 높인다는 커뮤니케이션 수준의 매개효과를 검증하였다는 점에서 의의가 있다. 그리고 변화관리와 조직 문화적 적합성이 요구되는 다른 유형의 정보시스템과 달리 기업용 SNS는 구성원들이 오프라인 커뮤니케이션 상의 문화적 한계를 우회하도록 지원함으로서 커뮤니케이션을 활성화하고 업무성과를 향상시킬 수 있음을 보여주었다는 점에서 의의가 있다.
