The purpose of this empirical case study is to explore what factors affect on the economic valuation of academic journals and to ascertain the degree of each impact. For this study, factors were categorized into three groups: internal factors external factors and demand theory factors. The on-line questionnaire was used to collect data and 383 responded from individual users of and the persons in charge of the DDS(Document Delivery Service). Collected data were analyzed using SPSS 12.0 for Windows/PC. The result showed that there exist a strong relationship between the internal factors of academic journals(i.e., Impact Factor, Cost, and Language) and economic valuation in terms of its use value.

With the increasing concern about natural resources that is being devastated and lost its reproductivity, Non-use value of resources for future use is considered more important than the present use value in the resource valuation. This study aims to measure Total Non-use value in Namsan Park, Kwanak and Paldal Mountain with CVM(Contingent Valuation Method). CVM is the method which can evaluate Non-use value of tourism resource to find the future value of the given resource. This study is carried on the assumption that respondents give answers not to real situation but to imaginary circumstances. After analysing benefit value by estimating conservation value and separate use value, we can conclude that conservation value of tourism resource is given much weight.

이 연구는 2003년에 실시된 한국종합사회조사(KGSS)의 가족모듈과 국제사회조사기구(ISSP)의 2002년 가족모듈을 이용해 한국의 가족가치를 국제적인 수준에서 비교 분석하고 있다. 한국에서는 최근 여러 가치와 태도가 급변하고 있다고 믿어지고 있다. 그 결과 세대간의 가치 및 태도의 차이가 크고, 이는 사회내 세대간 갈등의 뿌리라고도 이해되고 있다. 그러나 이에 대한 과학적인 검증은 많지 않다. 이 연구는 이런 시점에서 한국의 여러 가지 중 가족가치의 영역에서 세대간 가치가 크게 나타나고 있는지, 국제적인 수준에서 보면 우리나라의 세대간 가족가치 차이가 크다고 볼 수 있는지를 kurtosis라는 지표를 통해 분석하고 있다. 결혼, 동거, 이혼 및 부부의 성역할에 관한 가치 및 태도를 분석해 본 결과 한국인의 가족가치는 가톨릭이 지배적인 필리핀의 가족가치와 비슷할 정도로 매우 보수적이고 전통적인 것으로 나타났다. 일반적으로 가치관의 변화는 경제발전 정도에 크게 영향을 받는 것으로 알려져 있다. 그런데 한국은 한국보다 경제발전 정도가 크게 뒤져 있으면서 보수적인 가족가치관이 지배적인 필리핀과 가족가치의 수준이 비슷하게 나타나고 있다. 세대간 갈등의 원인이라고 볼 수 있을 정도로 가족가치의 세대간 차이가 큰지 kurtosis를 이용해 분석해 본 결과, 한국보다 오히려 일본의 세대간 가치관의 차이가 더 큰 것으로 나타났다. 한국에 세대간 가치관의 차이가 있지만, 외국과 비교해보면 한국의 세대간 가치관 차이가 더 두드러진다고는 보기 힘들다.

투자안 가치평가 방법에는 화폐의 시간가치를 고려한 방법과 고려하지 않는 방법이 있다. 이중 가장 많이 쓰이고, 중요한 방법으로는 화폐의 시간 가치를 고려한 순현재가치법(NPV), 내부수익률법(IRR), 수익성지표법(Pl)등이 있다. 이중에서도 우리는 투자사업으로부터 사업의 최종년도까지 얻게 되는 순이익(수익-비용)의 흐름을 현재가치로 계산하는NPV 분석을 많이 실시하고 있다. 즉, 어떤 자산의 NPV가 0보다 크면 투자 시 기업가치의 순증가가 발생하므로 투자가치가 있는 것으로 평가하고 0보다 작으면 기업가치의 순감소가 발생하므로 투자가치가 없는 것으로 평가한다. 여기에서 많은 기업경영자 및 재무담당자들은 다음과 같은 의문을 갖고 NPV분석의 약점을 보안할 필요성을 제기하고 있다. “결과로부터 얻은 단일 값이 정말 신뢰할 만한 값인가?”, “만약 몇 가지의 리스크 요인이 우리의 사업모델에 영향을 미친다면 그 결과는 어떻게 달라질 것인가?”, “우리가 얻은 결과 값의 실현 가능성은 몇%이고 나머지 발생 가능한 값들의 분포는 어떻게 될 것인가?” 위 질문에 대한 답을 얻을 수 있다면 투자안에 대해 빠르고 올바른 의사결정을 내릴 수 있으며 실패의 위험을 줄일 수 있다 이런 분석을 가능하게 해 주는 것이 확률론적 분석이며, 즉 몬테카를로 시뮬레이션 기법이다. 이미 많은 선진 기업에서 이 방법을 통하여 모든 의사결정에 중요한 참고 자료로 이용하고 있으며 본 논문은 몬테카를로 분석의 대표적인 소프트웨어인 Crystal Ball을 이용하여 그 활용 사례를 소개하고자 한다.

Association rules among product items by association analysis suggest sales effect among products. These are useful for marketing strategies such as cross-selling and product display etc. However, if we evaluate more practical product values reflecting cross-selling effects, they will be also more useful for the decisions of companies such as product item selection for product assortment and profit maximization etc. This study proposes product value evaluation models with the concept of effective value based on single-item association chain and itemset association chain. In addition to that, we performed experiments with transaction data related to clothing of an online shopping mall in Korea to show the performances of our models. In result, we confirmed that some items increased in effective values compared with their pure values while the others decreased in effective values.

This study investigated how Schwartz' value system(1992) would interfere with SNS users' motivations and behavioral responses. The study result shows that values are characterized in terms of openness, mutual reciprocity, self enhancement, normative compliance, and security. Each of them exerted differential impact on SNS usage motives, social capital, ad response, and word-of-mouth, among others. The five values were used as an input for segmenting SNS users and clustering method produced four value segments; experience seeker, interdependent sympathizer, self enhancer, and norm-bound. Each value group not only influenced SNS perceptions and behavioral responses differently, but also showed a systematic relationship with SNS service types. The study findings demonstrate that Schwartz's value system provides a very useful theoretical basis for understanding the psychological mechanism underlying SNS usage.

This study examined the multi-functionality of an eco-pastoral system in alpine grassland and measured its economic value. The multi-functionality can be divided into three categories: direct-use value, indirect-use value, and heritage value. Direct-use value includes both extractive (forage and livestock production) and non-extractive (recreation and tourism) functions. Indirect-use value includes the functions of water conservation, soil erosion control, atmospheric control, landscape, livestock-manure management, and forest firebreaks. The heritage value includes the function of species diversity. The results showed that the annual value for 1 hectare of the eco-pastoral system in alpine grassland's direct use was estimated to be 21,090,874 Korean won; the indirect-use value was 15,562,203 won when the landscape in grassland system, and 16,018,224 won when the landscape comprised in silvopastoral system. The value of the species diversity in heritage terms ranged from 767,273 to 1,578,845 won, depending on whether it included any endangered species. The total value of multi-functionality of the eco-pastoral system in alpine grassland was estimated to be a minimum of 37,420,350 won/ha and a maximum of 38,687,942 won/ha. The results of this study can provide useful insights for the eco-pastoral system in alpine grassland policies in Republic of Korea.

In this study, the value of the medical resort was divided into hedonic value, hospitality value, safety and personal information protection value, and profitability value by exploring and typifying the successful cases and related services of the medical resort in order to provide the direction of development and policy implications of the medical resort for the medical tourism industry. For those who have used the medical resort, I wanted to verify the impact of the value of medical resort on perception of medical resort and its intention to use it. As a result of this study, it was found that hedonic value and hospitality value of medical resort have a strong influence on usefulness perception and well-being perception of medical resort, that safety and personal information protection value of medical resort was only affected by usefulness perception, and profit value of medical resort was only affected by well-being perception. In addition, the usefulness perception and well-being perception of medical resorts were shown to have an impact on the intention of using medical resorts, especially in the case of well-being perception of medical resorts. The above findings are meaningful in that they expanded the medical resort-related research area for the medical tourism industry and provided useful implications for the development of medical resorts that meet the convenience and needs of medical tourists.

The purpose of this study is to verify effects between the place attachment and the place value in public libraries; and also to identify whether frequency and purpose of usage, length of residence, and website use play a moderating role in the influential relationship between users' place attachment and the perception of place value for public libraries. Users' place dependence affected the library's value positively(+) due to moderating effect of usage frequency of the library and the users' length of residence. In order to estimate the moderating effect by purpose of use, the groups were divided by purpose of library use and the relationship between place attachment and place value by groups were analyzed. However, website usage bore no effect on users' place attachment or perception of place value to their local library. This study showed that place attachment as an affective indicator on users is very useful variable to explain the value of libraries as a social and cultural place.

Voice technology allows consumers to make purchases through smart devices, and the interest in voice-driven conversational commerce has significantly expanded. In this study, we explored the continuance use intention of voice commerce, and the adoption of a value-attitude-behavior model. An online survey was conducted on 360 individuals who used an artificial intelligence assistant device in a voice commerce environment. We used Amos 23.0 and SPSS 25.0 for descriptive, confirmatory, and structural equation modeling analyses. These results indicated that functional value was the highest influencing variable on satisfaction of voice commerce, while social, emotional, and epistemic values significantly influenced it as well. Additionally, satisfaction of voice commerce significantly influenced the continuance use intention of voice commerce. These findings could help us understand the characteristics of voice commerce users and the diversity value in voice commerce environment.
