The purpose of this study is to examine whether suppliers are able to benefit by means of constructing a relationship-specific intangible asset and participating in collaboration with purchasers to actively maintain value created while mutually using inter-organizational information systems. To achieve the purpose of this study. 82 questionnaires have been analyzed from suppliers which are using electronic transactions through inter-organizational information systems. As a result, business process specificity and domain knowledge specificity, which are relationship-specific intangible assets, affect operational collaboration and strategic collaboration, which are classified by level of decision-making. Although both types of collaboration are needed to achieve both strategic and operational benefits, we find each collaboration to be uniquely promoted by a specific types of relationship-specific intangible asset. Operational collaboration is found to be an antecedent to operational benefit and strategic collaboration is found to be an antecedent to strategic benefits. No crossover between collaboration and supplier's benefits is found. Consequently, the result of this study shows collaboration is needed for domestic suppliers, which have relatively low levels of collaboration, to keep maintain relationship-specific intangible assets and to prevent the relationship termination cost when transactions have been stopped between supplier and purchaser. Also the results imply the supplier can have advantages by participating in collaboration.

In dehumidification evaporation cooling system. the regeneratie evaporative cooler(REC) makes an important role to reduce the sensible cooling load in the system through evaporative cooling, By this reason, many studies about increasing the cooling capacity of the REC were undertook. In this paper, we analyzed the cooling characteristics of the REC due to the structures of the REC and determined the best structure for the REC's effectiveness and cooling capacity. From the study. we could obtain some important results: at first. corrugated type has the benefit to expand the channel width of the REC, But because the type has some weak points about the size and weight. there is almost no benefit to improve the performance of the REC. Through these reasons. we decided that finned type is the best structure to improve the performance of the REC.

This study was aimed at examining the self-reported health-promoting life- style (HPL) and related factors among teachers assumed to be role models for students. The subjects were 300 teachers who were conviently drawn from nine elementary schools and three high schools. The conceptual framework for this study was based on the Pender's revised Health Promotion Model(1996). Data was collected by a mailed survey (response rate, 62.5％) with structured questionnaire. The score of health-promoting life-style was 2.8(full mark： 5.0), harmonized relationship was the highest(3.2), and professional helath management was the lowest(2.0). The related factors to health-promoting life-styles were age, marital stauts, career, perceived health status, self esteem, intermal locus of control, perceived benefit, perceived barrier, self efficacy, and social support in univariate analysis. In the final regression model, predictors of HPL were social support, self esteem, perceived benefit. self efficacy, and perceived health status after control the effects of demographic characteristics (p＜.0001, R2＝0.494). The results generally supported the Pender Model. It is recommended to develop the health promotion program for teachers based on these results, and to evaluate the effect of that program for teacher.

Purpose: This study intends to examine how VMI with consignment performs over time and find out its on-going impacts on the individual supply chain member's achievement. Research design, data, and methodology: This study formulates the mathematical model that represents two-stage supply chain system. By analyzing the numerical examples, this study compares VMI with consignment with the traditional system. Results: VMI with consignment eventually makes higher supply chain profit than the traditional system, even though it's early performance is poor. The influence of VMI with consignment on the performance of the supply chain member is distinct depending on the individual member and time. The consignment may not be helpful to increase the system profit, but it reduces the manufacturer's burden of costs. Conclusions: VMI with consignment improves the supply chain performance after all, and it still takes times until its benefit becomes fully realized. To be a successful collaboration program, VMI with consignment requires a carefully designed incentive scheme that provides the timely compensation to the individual supply chain members. This study also finds out that the consignment contract of this collaboration program plays a role of financially supporting the manufacturer at the early stage of its implementation.

Nepal is bestowed with abundant water. With more than 1500 mm average annual rainfall in the country, a vast quantity of underutilized groundwater in the Terai belt, and the water stored in snowcaps in the Himalayas, aquifers in the mountains and glacial lakes, Nepal is potentially in an advantageous position in terms of per capita availability. However, low emphasis in management aspect of water and high emphasis in infrastructural developments related to water resources management has resulted in conversion of water in Nepal from a resource to a burden. The global climate change, reduction in number of rainy days, increase in intensity of rainfall during wet monsoon season, encroachment of river banks for settlement, inadequate release of environmental flows from hydropower plants, and attempt to tame the mighty and high velocity rivers of Nepal have resulted in increasing number of water induced disasters (flood and landslide), rise in conflict between local residents and hydropower developers, higher number of devastating landslides, and in some extreme cases mass migration of residents resulting in climate refugees. There is a ray of hope; the awareness level of the people regarding sustainable use of water resources is increasing, the benefit sharing mechanism is gradually being implemented, the role of interdisciplinary and integrated water resources management is appreciated at a higher level and the level of preparedness against flood and landslides is at a higher degree compared to a couple of decades ago. With the use of renewable energy sources, the possibilities for sustainable and productive use of water are on the rise in Nepal.

이 글은 기초연금 인상만으로는 세계적으로 높은 한국의 노인빈곤율을 해소하기 어렵다는 점을 실증분석을 통해 밝히는 것이 목적이다. 패널자료를 이용하여 기초연금 인상대안 별로 빈곤완화효과를 추정한 결과 기초연금은 한국 노인의 절대빈곤을 완화하는데는 상당한 기여를 할 수 있는 것으로 분석되었다. 하지만 기초연금을 지금보다 2배 이상 인상해도 국제적 노인빈곤 기준인 상대빈곤율을 완화시키는 효과는 매우 제한적인 것으로 분석되었다. 이러한 분석을 근거로 이 논문은 기초연금의 정책목표는 사회적으로 합의된 절대빈곤의 해소에 두어야 하며 상대빈곤의 해소는 소득비례연금인 국민연금의 소득대체율 조정을 통해서 이루어져야 한다는 점을 주장한다.

Purpose The purpose of this study is to understand the factors that influence the purchasing behavior of NFT collectibles consumers, using the value-based acceptance model (VAM). As the use of NFTs is predicted to become more widespread in the near future, it is important to explore how these consumers make purchasing decisions. Design/methodology/approach This study employed text analysis and in-depth interviews to identify the factors of benefits and sacrifices perceived by consumers. Based on the results of the exploratory study, a research model and hypotheses were established. To test the hypotheses, an online survey was conducted, and the data was analyzed using a structural equation model. Findings The major findings of this study showed that perceived benefit factors had a significant positive impact on consumers' perceived value of NFT collectibles, whereas perceived sacrifice factors did not have a significant effect on perceived value. Also, when consumers' social needs were met, their perceived value was highest. Lastly, the effect of perceived value on purchase intention was not affected by the level of psychological ownership.

플래시 메모리에서 읽기 작업은 속도도 빠르고 제약이 없으나 데이터 변경 시에는 덮어쓰기(overwrite)가 되지 않아 해당 데이터를 새로운 영역에 쓰고 이전에 존재하던 데이터는 무효 시켜야한다. 무효화시킨 데이터는 가비지컬렉션을 통해 지움 연산을 수행해야 한다. 지역 접근성을 가지는 데이터에 대해 가비지컬렉션을 통해 클리어 시킬 대상 목록을 선정할 때 cost-benefit 방법을 사용하면 성능은 좋으나 wear-leveling이 나빠지는 문제점이 있다. 본 연구에서는 wear-leveling을 개선하기 위해 플래시 메모리를 hot 데이터 그룹들과 cold 데이터 그룹들의 다수의 그룹으로 분할한 후 데이터를 배치하고 주기적으로 hot 데이터 영역과 cold 데이터 영역을 교체함으로써 wear-leveling과 성능을 개선하였다.
