We investigated the effect of temperature and stock density on the collection efficiency of oral fluid in the pig farm in Korea. Three pig farms with similar breeding environmental conditions were selected and four pens of each farm (total 12 pens) were tested for the collection efficiency of oral fluid from pigs. Collection rate was considered as significant when oral fluid was collected from 70% of pigs within a pen. In the case of growing pigs, when internal temperature of pig barn increased by one designated degree (5℃), the oral fluid collection rate significantly decreased by 24.7% (P<0.05). The collection rate of oral fluid also decreased by 7.1% (P<0.05) as the density rate increase by one designated degree (12.5%). It was estimated that the collection efficiency of oral fluid decreased when the internal temperature of pig barn was 30℃ or higher, or barn density is higher 25% or high. On the other hand, in the case of stall-housing sows, unlike growing pigs, there was no significant differences according to the temperature, so oral fluid collection was considered to be efficient even in hot season.

기존의 성과평가 모형은 공급자 중심의 객관적 자료를 중심으로 하는 평가모형으로서 이용자 중심의 평가가 반영되지 못하는 한계를 보이고 있다. 최근 들어 이용자 중심의 성과평가가 강조됨에 따라 이용자 만족도가 성과평가의 기준으로 사용되고 있다. 바우처 서비스가 확대됨에 따라 정부와 이용자가 서비스 이용에 있어 재원을 부담하는 바우처의 속성상, 정부와 이용자에 대한 책무성을 담보하여야 할 필요성에 따라 정부 측면과 이용자 측면의 평가지표가 모두 반영되는 평가모형이 활용되고 있다. 그러나 성과평가의 기준의 활용과 해석에 대한 사회복지학 분야의 연구는 부족한 상황이다. 이에 본 연구에서는 이용자 만족도를 평가하는 주관적 성과와 기관운영의 효율성을 평가하는 객관적 성과간의 연계성을 분석하였다. 분석대상 자료는 지역개발형 지역사회서비스투자사업의 설문자료이며 총 70개 서비스 제공기관과 이용자 1445명의 자료를 분석하였다. 종합만족도 지수 산출방식을 적용하여 이용자 만족도를, 자료포락분석(DEA)기법을 적용하여 효율성 지수를 산출한 후, 두 지표간의 상관관계를 분석하고 포트폴리오 맵을 활용하여 두 성과지표의 해석을 시도하였다. 본 연구는 바우처 서비스에 있어서 성과평가 기준 간의 관계에 대해 이론적 설명을 시도하였으며, 실천적 측면에서 성과평가 기준 설정 및 해석에 있어 함의를 제공하고 있다.

Purpose: Purpose: This study examines the optimization of healthcare service distribution through digital channel adoption by integrating anticipatory governance perspectives with distribution channel frameworks, emphasizing the role of digital service delivery networks. Research design, data and methodology: The research employs a mixed-methods approach incorporating qualitative expert interviews and quantitative survey data from 295 users across diverse distribution regions of Vietnam. The conceptual framework analyzes the relationships between distribution service quality, security protocols, perceived distribution benefits, and future perception through Partial Least Squares Structural Equation Modeling, focusing on channel efficiency and service accessibility. Results: The findings reveal that service quality and security measures in digital channels significantly influence attitudes toward distribution systems, while traditional usability factors show minimal impact. The study introduces future perception as a novel construct in distribution science, demonstrating its significant effect on adoption intentions. Multi-group analysis reveals notable variations in distribution effectiveness across geographical regions and demographic segments, with distinct patterns between urban and rural areas. Conclusions: The research advances distribution theory by demonstrating how anticipatory elements and demographic variations influence digital service delivery optimization. These insights provide strategic implications for developing efficient, segment-specific digital distribution networks in healthcare service delivery.

This experiment was conducted to investigate the variation of nitrogen use efficiency, nitrogen uptake efficiency, physiological utilization efficiency and their relationships with growth characteristics in the 28 Korean rice cultivars. Nitrogen use efficiency of 28 rice cultivars was 47.74, nitrogen uptake efficiency was 0.71, and physiological utilization efficiency was 68.76 in average. Nitrogen use efficiency of rice cultivars had low variation ranged from 44.09 to 51.91, but nitrogen uptake efficiency were relatively high variation from 0.51 to 0.90, and physiological utilization efficiency was from 51.71 to 94.26. The high efficient group in nitrogen uptake efficiency whose value was calculated above 0.80 included Daeanbyeo, Seojinbyeo, Ansungbyeo, Dongjinbyeo, and Hwaanbyeo, while the low efficient group with below 0.60 was Kwanganbyeo, Sampyeongbyeo, Soorabyeo, and Hwasungbyeo. Hwasungbyeo, Sampyeongbyeo, Soorabyeo for physiological utilization efficiency were more efficient cultivars, while Daeanbyeo, Seojinbyeo, Ansungbyeo were less efficient cultivars. Nitrogen uptake efficiency had positive correlation coefficients between dry matter weight of plant ($0.842^{**}$), leaf area index ($0.761^{**}$), and leaf nitrogen content ($0.599^{**}$), respectively. Therefore, the dry matter weight of rice plant and leaf area index was important characters to evaluate nitrogen uptake efficiency in rice cultivars. Also, more efficient cultivar in nitrogen uptake had higher chlorophyll meter value, which was appeared dark green color.

Purpose: One distinctive trend in the recent industrial and technological development has been the change in the structures of industries brought by information technology, boosting the productivity of different sectors. This relation has clearly opened a path for the fourth industrial revolution to reform numerous industrial sectors, including i-fashion sectors. Therefore, in this research, we would like to present the direction of the direction policy for the fusion of the manufacturing industry and the service industry of i-fashion. Methods: In this study, an empirical time series data analysis of machinery investment efficiency and capital investment efficiency of 43 industrial sectors in manufacturing and service was conducted to show their potential and ongoing convergence toward i-fashion. Results: Most impressive as a finding in this research was that those sectors previously underinvested due to a combination of technological and financial reasons found an exit for growth. In textile and apparel sectors, that could be the i-fashion. Conclusion: One strong implication of this study is that sectoral level convergence based on technology and industry is occurring, and i-fashion is one of the industrial convergence case to be observed.

By far, numerous e-government projects requiring huge investments have been conducted in Korea to increase the administrative efficiency and improve the service quality via Internet. However, there's little research focusing on methods and techniques for analyzing and evaluating the projects either to economically justify the investments or to assess the quality of the system and of on-line services to citizens. The purpose of this paper is to suggest a set of factors to take into account for evaluating e-government portals and to empirically test the factors to provide useful implications for building such portals. Based on the literature reviewed, we constructed a research model that includes content, public service, community, design, technology, and portal's attributes as independent variables and the user's satisfaction and the administrative efficiency as dependent variables. A reliability test revealed that the evaluation factors proposed in the paper are sufficiently reliable, and a multi-regression analysis indicated that five hypotheses should be accepted. The findings of the study suggest that emphasis should be placed on public service quality and portal site attributes, among others, when implementing portals.

BIM-based Cloud platform gained popularity coupled with the convergence of Fourth Industrial Revolution technology. However, most of the previous work has not guaranteed sufficient efficiency to meet user requirements according to BIM service. Furthermore, the Cloud environment is only used as a server and it does not consider cloud characteristics. For the processing of High Capacity Data like BIM and using seamless BIM service, Resource management technology is required in the cloud environment. In this paper, to solve the problems, we propose a BIM platform for BaaS and an efficient resource allocation scheme. We also proved the efficiency of resource for the proposed scheme by using existing schemes. By doing this, the proposed scheme looks forward to accelerating the growth of the BaaS through improving the user experience and resource efficiency.

During the Covid-19 pandemic, social distance regulation calls for non-contact services, making self-service technologies gain much more attention. However, customers found they are pushed into more digital shadow work by employing Self-service technologies (SSTs). This research aims to examine how digital shadow work influences user emotions and behaviors during SSTs use. Based on the grounded theory method (GTM), this draft drives 128 codes and 7 categories to develop the theory of digital shadow work. Operations, consisting of pre-use, during use, and after use, along with the cognitions, including the perception of use-value and time efficiency, act as the trigger of digital shadow work. Achievement emotions, embodying happiness and satisfaction from technology use, result from the perception of high use-value and high time efficiency, while loss emotions, encompassing anger and disappointment from the user experience, generate from the perception of low use-value and low time efficiency, and finally, user responses from the digital shadow work - quitting, continuous and alternative behaviors are found as key factors. The interventing roles of a sense of control, system features, and compensation are also addressed. Examining users' psychological mechanisms academically contributes to developing the theory of digital shadow work whereas it advances the development of SSTs on a practical side.
