This study aims to develop the trustworthiness model for public digital records, as an admissibility framework for establishing trust. The trustworthiness model is deemed to used to identify the qualities of the digital records in their lifecycle, including the identity that could be identified at the time of the creation, integrity obtained from the chain-of-custodial management, the evidence of relationship between business activities and records, and the technical or cognitive accessibility. Based on the analysis of the QADEP model, it was decided to develop a model that could measure the trustworthiness of public digital records in the external measurement type, which are authenticity, reliability, and usability. In line with this direction, the model expanded measurement areas and indicators of the QADEP model through the analysis of ISO 16175-1:2020, and measuring metrics was also proposed so that it could be a measuring instrument for public digital records in Korea, after analysing NAK 19-3. It would be useful to expand the model and to test the approach of the trustworthiness model for public digital records.

효율적인 대기질 개선정책을 위해서는 비용-편익이 반드시 필요하다. 대기질과 관련된 편익은 건강영향을 비롯하여 시정장애, 심미적 가치, 물질피해 등 많은 영향이 존재하는데 그 중 건강영향이 대부분을 차지하는 것으로 보고되고 있다. 본 연구에서는 대기오염과 관련된 건강영향 중에서 눈이 따가운 증상, 가슴이 답답한 증상, 그리고 천식증상에 관하여 서울시민들이 부여하는 경제적 가치를 조건부 가치측정법을 이용하여 측정하였다. 그 결과 눈이 따가운 증상은 2,850원, 가슴이 답답한 증상은 9,000원, 천식은 5만 5,400원으로 측정되었다. 또한, 하나의 설문에서 여러 개의 CV 질문을 수행하는 경우, 일반적으로 추정하는 일변량 모형과 이변량 모형의 추정결과는 다르다는 것을 알 수 있었다.

인터넷의 생활화를 통해 우리 생활 패턴이 크게 변화하였다. 특히 상품 구매의 경우 온라인 시장의 성장과 상품 정보의 범람으로 소비자들의 구매 의사결정은 더욱 어려워졌다. 따라서 효율적인 상품 구매 의사결정을 위해서는 소셜 네트워크 분석(Social Network Analysis)을 기반으로 한 더 가치있는 정보를 선별하여 제공해 줄 수 있는 서비스가 필요하다. 따라서 본 논문에서는 온라인 소셜 네트워크 요소 분석을 통해 상품 후기에 대한 개인화된 가치 측정값 정보를 제공함으로써 소비자의 보다 효율적인 상품 구매가 가능하도록 도와주는 '가치 측정 알고리즘'을 제안한다.

본 연구의 첫 번째 목적은 Service Quality를 측정하는데 있어서 기대와 성과 측정치를 차감하는 차감식(difference score)에 의한 방법(SERVQUAL), 지각된 성과만으로 개념화/조작화 하는 방법(SERVPERF), 차이를 한 번에 직접 측정하는 방법(non-difference score) 중 어느 방법이 가장 타당한지를 조사하는 것이다. 본 연구의 두 번째 목적은 서비스품질뿐만 아니라 서비스가치 construct가 만족과 구매의도에 대한 선행변수로서 갖는 이론적 가치를 조사하는 것이다. 전국의 특 1급, 특 2급, 1급 호텔 148개의 투숙객을 대상으로 설문조사가 이루어졌다. 연구결과 SERVQUAL이나 SERVPERF에 의한 방법보다는 비차이척도를 이용하는 방법이 보다 높은 설명력을 갖는 것으로 나타났다. 또한 만족과 구매의도에 미치는 영향력에 있어서 서비스품질 뿐만 아니라 서비스가치 또한 유의적인 영향력을 갖고 있는 것으로 나타났다. 끝으로 연구결과와 관련하여 추가적인 논의를 하였다.

Under conditions of increasing environmental uncertainty, firms' risk management become important. This study examines the impact of foreign currency derivative usage on firm value using 3,004 Korean non-financial firms from 2002 to 2007. The results showed that there was no significant relationship between foreign currency derivative usage and firm value for the whole period and from 2002 to 2004 when exchange rate was relatively less volatile. But form 2005 to 2007 when exchange rate was volatile, foreign currency derivative usage gave significant negative impact on firm value, whereas when contract value was used, the relatinship was significantly positive. These results might be come from the characteristics of contract value and fair value of foreign currency derivatives. increased firm value when contract value was used as foreign currency derivative usage measure. But when fair value was used, there was no significance. For control variables, major shareholders ownership and foreign blockholders ownership was positively related with firm value.

The purpose of the present study was to examine the relationship between individual values, nature-relatedness, and happiness in a sample of Korean university students(N=224). Specially, we used Schwartz's PVQ, life satisfaction, positive affect, psychological well-being, social well-being, and Korean Happiness scale to measure values and happiness. According to the bivariate correlational analysis, generally, there were positive correlation between benevolence, self-direction, universalism, stimulation and one of 5 happiness measurements and there was negative correlation between achievement and life satisfaction. Nature-relatedness were positively related with five types of happiness measurements. According to the hierarchical regression, demographic variables(sex, religion, economic levels), value types, and nature-relatedness explained 25%~36% of variance in happiness. Value was more related with psychological well-being than life satisfaction, positive affect, social well being, Korean happiness scale. This results emphasize the importance of healthy value(benevolence, self-direction) and provision of opportunities contact with nature to promote human happiness.

This study aims to suggest a new approach to economic valuation of the special library, in response to the necessity of economic justification of the special library operated by firms and research institutes. Benefit measurement elements and analysis methods to be used in the study were derived through feasibility evaluation on models in previous studies, and objectivity and applicability were the criteria for feasibility evaluation. Depending on which type of resources are used in providing service, different benefit measurement elements and methods were applied. Based on this, calculation formula for service valuation of special library was presented. The development of analysis model for economic valuation of special library made it possible to objectively prove the value of the special library, and is considered to provide an opportunity to publicize the real value of the special library.

Annual total values and thereby assets values of natural resources are determined by sample household WTP estimates and the extent of market. In the current domestic practice of CVM, total numbers of national households were used as the target population to measure total economic values including non-use values. This study proposed an alternative method of calculating potential user groups based on distributions of residential area of visitors in the sample using 4 provincial parks in the Chon Buk area as cases. The sample mean of WTP of Moak Mt. visitors, who are mostly from the nearby Chon Buk provincial area, was estimated to be about 8,215 won. On the other hand, the mean of WTP of Sun Woon Mt., whose visitors are evenly distributed from all over the country, was about 4,693 won. When applied national households as the target population, annual total benefits and thereby asset values of Moak Mt. was high enough to be 86 billion and 1.6 trillion won respectively. However, those of Sun Woon Mt. was low to be 52 billion and 1 trillion. On the contrary, when applied potential user groups of each park as the extent of market, annual total benefits and asset values of Sun Woon Mt. was reversed to be high--23 billion won and 400 billion won respectively. However, those of Moak Mt. was lowered to be 10 billion won and 200 billion won. Furthermore, asset values of the same park were differed by 2 to 8 times according to the way of setting the extent of market.
