UGC(User Generated Contents) is emerging as the center of e-business in the web 2.0 era. The trend reflects changing roles of users in production and consumption of contents on websites and helps us to understand new strategies of websites such as web portals and social network websites. Nowadays, we consume contents created by other non-professional users for both utilitarian (e.g., knowledge) and hedonic values (e.g., fun). Also, contents produced by ourselves (e.g., photo, video) are posted on websites so that our friends, family, and even the public can consume those contents. This means that non-professionals, who used to be passive audience in the past, are now creating contents and share their UGCs with others in the Web. Accessible media, tools, and applications have also reduced difficulty and complexity in the process of creating contents. Realizing that users create plenty of materials which are very interesting to other people, media companies (i.e., web portals and social networking websites) are adjusting their strategies and business models accordingly. Increased demand of UGC may lead to website visits which are the source of benefits from advertising. Therefore, they put more efforts into making their websites open platforms where UGCs can be created and shared among users without technical and methodological difficulties. Many websites have increasingly adopted new technologies such as RSS and openAPI. Some have even changed the structure of web pages so that UGC can be seen several times to more visitors. This mainstream of UGCs on websites indicates that acquiring more UGCs and supporting participating users have become important things to media companies. Although those companies need to understand why general users have shown increasing interest in creating and posting contents and what is important to them in the process of productions, few research results exist in this area to address these issues. Also, behavioral process in creating video UGCs has not been explored enough for the public to fully understand it. With a solid theoretical background (i.e., theory of implementation intentions), parts of our proposed research model mirror the process of user behaviors in creating video contents, which consist of intention to upload, intention to edit, edit, and upload. In addition, in order to explain how those behavioral intentions are developed, we investigated influences of antecedents from three motivational perspectives (i.e., intrinsic, editing software-oriented, and website's network effect-oriented). First, from the intrinsic motivation perspective, we studied the roles of self-expression, enjoyment, and social attention in forming intention to edit with preferred editing software or in forming intention to upload video contents to preferred websites. Second, we explored the roles of editing software for non-professionals to edit video contents, in terms of how it makes production process easier and how it is useful in the process. Finally, from the website characteristic-oriented perspective, we investigated the role of a website's network externality as an antecedent of users' intention to upload to preferred websites. The rationale is that posting UGCs on websites are basically social-oriented behaviors; thus, users prefer a website with the high level of network externality for contents uploading. This study adopted a longitudinal research design; we emailed recipients twice with different questionnaires. Guided by invitation email including a link to web survey page, respondents answered most of questions except edit and upload at the first survey. They were asked to provide information about UGC editing software they mainly used and preferred website to upload edited contents, and then asked to answer related questions. For example, before answering questions regarding network externality, they individually had to declare the name of the website to which they would be willing to upload. At the end of the first survey, we asked if they agreed to participate in the corresponding survey in a month. During twenty days, 333 complete responses were gathered in the first survey. One month later, we emailed those recipients to ask for participation in the second survey. 185 of the 333 recipients (about 56 percentages) answered in the second survey. Personalized questionnaires were provided for them to remind the names of editing software and website that they reported in the first survey. They answered the degree of editing with the software and the degree of uploading video contents to the website for the past one month. To all recipients of the two surveys, exchange tickets for books (about 5,000~10,000 Korean Won) were provided according to the frequency of participations. PLS analysis shows that user behaviors in creating video contents are well explained by the theory of implementation intentions. In fact, intention to upload significantly influences intention to edit in the process of accomplishing the goal behavior, upload. These relationships show the behavioral process that has been unclear in users' creating video contents for uploading and also highlight important roles of editing in the process. Regarding the intrinsic motivations, the results illustrated that users are likely to edit their own video contents in order to express their own intrinsic traits such as thoughts and feelings. Also, their intention to upload contents in preferred website is formed because they want to attract much attention from others through contents reflecting themselves. This result well corresponds to the roles of the website characteristic, namely, network externality. Based on the PLS results, the network effect of a website has significant influence on users' intention to upload to the preferred website. This indicates that users with social attention motivations are likely to upload their video UGCs to a website whose network size is big enough to realize their motivations easily. Finally, regarding editing software characteristic-oriented motivations, making exclusively-provided editing software more user-friendly (i.e., easy of use, usefulness) plays an important role in leading to users' intention to edit. Our research contributes to both academic scholars and professionals. For researchers, our results show that the theory of implementation intentions is well applied to the video UGC context and very useful to explain the relationship between implementation intentions and goal behaviors. With the theory, this study theoretically and empirically confirmed that editing is a different and important behavior from uploading behavior, and we tested the behavioral process of ordinary users in creating video UGCs, focusing on significant motivational factors in each step. In addition, parts of our research model are also rooted in the solid theoretical background such as the technology acceptance model and the theory of network externality to explain the effects of UGC-related motivations. For practitioners, our results suggest that media companies need to restructure their websites so that users' needs for social interaction through UGC (e.g., self-expression, social attention) are well met. Also, we emphasize strategic importance of the network size of websites in leading non-professionals to upload video contents to the websites. Those websites need to find a way to utilize the network effects for acquiring more UGCs. Finally, we suggest that some ways to improve editing software be considered as a way to increase edit behavior which is a very important process leading to UGC uploading.

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 objective of this study is to conduct survey analyses of the role perception and performance of homeroom teachers in elementary schools in Seoul as well as their students' expectations for teachers' role as counsellors. The study also aims to analyze the causes behind the lackluster performance, to provide assistance in teachers' counselling and guidance activities and collect basic data for providing a plausible orientation for elementary school counselling. Research topics for achieving these study objectives are as follows. First, what is the status quo of counselling between elementary school students and teachers? Second, what is the role perception of elementary school homeroom teachers as counsellors and their current level of performance? Third, what are the differences in students' expectations for homeroom teachers' role as counsellors according to students' environmental variables such as gender and grade? Fourth, what are the discrepancies between the roles perception and performance of elementary school homeroom teachers and role expectation of students for homeroom teachers' role as counsellors? In order to answer these questions, surveys were conducted for 229 teachers and 385 students in grades 4, 5 and 6 in 11 elementary schools in Seoul, and the results were analyzed. The questionnaires used for this study were modified and supplemented according to the research objectives based on survey questions released by Gyung-Beom Lee(1989), Hak-Soo Lee(2001) and Gi-Nam Gwon(2005). Statistical analyses were peformed using the SPSS for Windows 10.0 program. The results of the study can be summarized as follows. First, most elementary school homeroom teachers were involved in counselling activities, and about half of them were providing counselling once a month or less. The classroom was the primary location of counselling, and more than half of the surveyed teachers were dissatisfied with their counselling activities. The teachers cited overwhelming teaching hours and excessive work as the factors that made counselling difficult. Second, it was revealed that most elementary school students have had experiences of anguish and most have had some form of counselling. They mostly sought counselling from their parents and friends, and the reasons behind such choices were that they were very understanding. Third, most students responded that they have had no experience of receiving counselling from their homeroom teachers. Among those with counselling experience with their homeroom teachers, most said that the counselling was helpful. The most significant reason for not receiving counselling from their homeroom teachers was that the students had no worries to talk about with their teachers. Fourth, as a result of categorizing the role of elementary school homeroom teachers as counsellors according to the areas of counselling, role perception for each area turned out to be generally high, while performance was substantially lacking. Fifth, in terms of the causes for the lackluster counselling performance, overwhelming teaching hours and excessive work were indicated for counselling areas of academic and personality issues. Sixth, the analysis of students' expectations for elementary school homeroom teachers as counsellors for counselling areas according to gender and grade revealed that there was no overall statistical significance. Seventh, from the general perspective, the level of role perception of the homeroom teachers were higher than the level of students' expectations. In conclusion, in order to enhance the teacher's role as a counsellor, there has to be a concrete perception of roles as a primary premise, calling for training sessions and programs dedicated to counseling for the teachers to take part in. Moreover, in order to alleviate the most significant causes for undermining teachers' counselling activities - overwhelming teaching hours and excessive work - there must be administrative consideration as well as provisions for effective counselling centers and dedicated school counsellors.

본 연구는 충남지역 전체 행정 구역인 14개 시 군에 소재하는 초 중 고 급식학교를 골고루 포함시켜 305교를 편의 추출하고 각 학교에 근무하는 조리원 1명씩을 무작위 추출해 총 305명의 조리원을 대상으로 자기기입식에 의한 설문조사를 실시하였다. 본 연구는 학교급식 조리원의 학교급식 관련 위생지식 및 학교급식위생관리지침서 3차 개정에 준한 HACCP 수행도를 조사해 학교급식 위생수준 향상을 위한 기초자료로 제공하는 데에 목적을 두었다. 연구 결과 조리원의 학교급식 관련 위생지식 수준이 높을 때 HACCP 수행도가 높아 조리원의 위생지식 수준이 HACCP 수행도에 중요한 영향을 미치는 요인으로 파악되었다. 그러나 초 중 고 중에서 초등학교로 갈수록 조리원의 위생지식 수준은 높으나 초등학교에서 일부 항목의 HACCP 수행도가 낮았는데, 이는 본 연구 대상 초등학교가 중학교와 고등학교에 비해 면단위 농촌형 소규모 학교가 많아 HACCP 수행에 필요한 인력과 시설 설비 기구를 적정하게 보유하지 못하고 있기 때문으로 여겨진다. 따라서 소규모 학교에 대한 인적 물적 자원의 지원이 이루어질 필요가 있었다. 그리고 고등학교에서 조리원의 HACCP 수행도가 낮은 것은 이들의 HACCP 위생교육 횟수 부족에 따른 위생지식 수준이 낮은 점과 관련이 있으므로, 고등학교 조리원에게 1일 3식의 과다한 업무 속에서 짧은 시간 내에 취약 항목인 조리 전후 식재료나 음식의 취급 및 보관 등에 관한 위생교육을 자주 실시할 수 있도록 돕는 교육자료를 개발해 제공할 필요가 있었다. 중학교의 경우 조리원의 위생지식 수준과 HACCP 수행도가 높으며 학교급식 HACCP 관련 시설 설비 기구를 잘 갖추고 있어서 양호하였다. 그러나 본 연구는 충남지역 초 중 고에 근무하는 조리원을 대상으로 조사한 결과이어서 표집이 제한되어 있으므로, 연구 결과를 일반화하기에는 제한점을 가지고 있다. 앞으로 학교급식에서 지속적으로 문제가 되고 있는 위생관리에 관한 현장연구가 활발히 이루어지고 이 결과를 반영한 위생교육이 활성화됨으로써 학교급식 조리원의 위생지식 수준과 현장실천도를 높여 학교급식 품질을 향샹시켜 나가야 할 것으로 생각된다.

In the service-oriented economy, knowledge and skills are considered core resources to secure competitive advantages and service innovation. Knowledge management capability, which facilitates to produce, share, accumulate and reuse knowledge, becomes as important as knowledge itself to create service value. Along with knowledge management capability, dynamic capability and operational capability are the key capabilities related to managing service delivery processes. Previous studies indicated that these three capabilities are related to service innovation. Although separately investigate the relationship between the three capabilities. The purpose of this study is 1) to define variables that have effects on service innovation including knowledge management capability, dynamic capability and operational capability, and 2) to empirically test to identify relationship among variables. In this study, knowledge management capability is defined as the capability to manage knowledge process. Dynamic capability is regarded as the firm's ability to integrate, build, and reconfigure internal and external competences to address rapidly changing environments. Operational capability refers to a high-level routine that, together with its implementing input flows, confers upon an organization's management a set of decision options for producing significant outputs of a particular type. The proposed research model was tested against the data collected through the survey method. The survey questionnaire was distributed to the managers who participated in an educational program for management consulting. Each individual who answered the questionnaire represented a knowledge based service firm. About 212 surveys questionnaires were sent via e-mail or directly delivered to respondents. The number of useable responses was 93. Measurement items were adapted from previous studies to reflect the characteristics of the industry each informant worked in. All measurement items were in, 5 point Likert scale with anchors ranging from strongly disagree (1) to strongly agree (5). Out of 93 respondents, about 81% were male, 82% of respondents were in their 30s. In terms of jobs, managers were 39.78%, professions/technicians were 24.73%, researchers were 12.90%, and sales people were 10.75%. Most of respondents worked for medium size enterprises (47,31%) in their, less than 30 employees (46.24%) in their number of employees, and less than 10 million USD (65.59%) in terms of sales volume. To test the proposed research model, structural equation modeling (SEM) technique (SPSS 16.0 and AMOS version 5) was used. We found that the three organizational capabilities have influence on service innovation directly or indirectly. Knowledge management capability directly affects dynamic capability and service innovation but indirectly affect operational capability through dynamic capability. Dynamic capability has no direct impact on service innovation, but influence service innovation indirectly through operational capability. Operational capability was found to positively affect service innovation. In sum, three organizational capabilities (knowledge management capability, dynamic capability and operational capability) need to be strategically managed at firm level, because organizational capabilities are significantly related to service innovation. An interesting result is that dynamic capability has a positive effect on service innovation only indirectly through operational capability. This result indicates that service innovation might have a characteristics similar to process innovation rather than product orientation. The results also show that organizational capabilities are inter-correlated to influence each other. Dynamic capability enables effective resource management, arrangement, and integration. Through these dynamic capability affected activities, strategic agility and responsibility get strength. Knowledge management capability intensify dynamic capability and service innovation. Knowledge management capability is the basis of dynamic capability as well. The theoretical and practical implications are discussed further in the conclusion section.

현재 전 세계적으로 기후변화가 농업에 미치는 영향도가 점차 커지고 있다. 본 연구는 기후변화가 축산 생산성 변화에 미치는 영향 정도를 파악하고자 하였다. 기후변화 요소들 중 가장 큰 영향력을 지닌 변수들을 선행연구와 전문가 조사를 통해 알아보았다. 그리고 현재 축산농가들의 실질적 생산성 자료를 이용하여 기후변화와의 관계성에 대해 알아보았다. 가축 등 농업 생산성 변화에 관한 기후 평가를 위해 국내에서 축종별(한우(거세우), 낙농, 양돈, 산란계, 육계) 등의 전국 대표 자료들을 조사하였다. 또한 평가지표를 선정하고 분류하기 위하여 선행연구로서 기후변화 요인 변수선정 연구, 기후변화 요인 변수의 가중치 계산연구 등을 살펴보았다. 본 연구는 축산부문에 있어서 산학연 및 농민 등이 전문가(한우17, 낙농15, 양돈36, 산란계16, 육계15명)를 활용하여 기후변화 취약성 평가지표에 대한 설문조사를 실시한 후 계층분석과정(AHP)을 이용하여 선정된 평가지표의 가중치를 산정하였다. 축산 생산성에 기후변화가 미치는 영향력 평가 AHP 분석 종합결과 사양관리기술, 시설, 기후 순으로 중요도가 나타났다. 이것은 시설, 기후에 대한 통제부분을 현재 축산분야에 있어서는 어느 정도 평균수준 이상으로 경영되고 있기 때문으로 판단해 볼 수 있으며, 본 연구가 기후변화에 대한 영향도 연구이므로 기후요인만을 살펴볼 경우에 축산 생산성 관련 중요 기후요인은 모든 축종에서 최고기온, 고온일수 및 일교온도차로 조사되었고, 축종 별로 기후요인의 우선순위에는 차이가 있었다. 모든 축종에서 고온일수가 가장 영향력이 큰 요인으로 조사되었으며, 2순위로 최고기온과 일교차가 있었다. 2순위 최고기온은 거세우, 낙농, 양돈에서 영향력이 더 컸으며, 일교차는 산란계와 육계에서 더 중요한 요인으로 평가되었다. 이에 평가지표의 타당성을 검증하기 위해 국내 기후, 강수량 및 일조시간의 변화를 조사하여 축산부문에서의 각 축종별 생산성에 영향을 주는지에 대해 조사된 축산분야 농가들의 생산성 데이터를 통해 관계성을 알아보았다. 관계성을 알아보기 위해 축종별 생산성을 대표할 수 있는 주요 생산지표(사료섭취량, 사료요구율, 사료비, 도체중, 육질, 유생산량, 유지율, MSY, 육성율, 산란율 등)들과 선행연구들을 통해 결정된 기후변화 변수(기상청의 지역별·월별자료)들 간의 상관관계 및 회귀 분석을 수행하였다. 이와 같이 본 연구결과 기후변화요인들이 축산 생산성에 영향을 미치고 있음을 도출, 관계성이 있다는 것을 알 수 있었다. 기후변화는 현재도 진행 중으로 지구온난화는 고온일수 빈도를 높이고 있으며 이것은 단순한 기온 상승이 아닌 재해형태의 영향력 및 빈도의 심각성도 내포하고 있다는 것을 의미한다. 따라서 축산환경에 있어 이러한 기후변화에 대응하는 적극적인 환경관리 및 제어기술을 사전에 확보할 필요가 있을 것이다. 또한 향후 축산 생산성 연구에 있어서 기후변화 요인들을 제어할 수 있는 사육환경과 사양시스템에 포커스를 맞추어 이와 관련된 세분화된 연구들이 이루어져야 할 것이며, 국내의 경우 기후변화 조사 및 연구에 있어 보다 민감도를 높여 이루어질 필요가 있을 것이다.
