The desire to maintain health is increasing, consequently the role of nursing which has as one chief aim the solving of man′s basic problems is more and more important. Today, in spite of a growing concern about the nursing activities which nurses provide for individual human having specific needs, clinically in fact, it is questionable that individual′s expectation of nursing activities agrees with nurse′s performance of nursing activities. In this study the importance and agreement of the importance of the nursing activities during the hospitalized puerperal period as viewed by women in the puerperal period and by nurses caring for them, were assessed. The present study was undertaken in an attempt to furnish the basic data for expediting the progress of research activities in this area and further to be helpful in planning maternity nursing practice. The study population defined and selected was nurses (13) caring for women in the puerperal period and doing duty on obstetric & gynecologic ward at Y. hospital, and the women in puerperal period (39) as sum of 3 women selected by each nurse during the period of May 13th-June 4th 1976. The study data was collected by the direct interview method based on the questionnaire which the investigator made out. The study result was analyzed by percentage, t - test. The findings can be summarized as follows: 1. General characteristics of nurses doing duty on puerperal ward: a. Nurses′average age was 24.8 years old. b. 84.6% had educational background of 4 years of college. c. 69.2% had a religion. d. 53.8% were married. e. 53.8% had clinical experience of 1 year -3 years. f, 61.5% did duty on puerperal ward during 1 year -3 years. g. 46.2% desired to do duty on obstetric ? gynecologic ward. 2. General characteristics of the women who were studied during their puerperal period: a. Women′s average age was 26.4 years old. b. 79.5% had educational background above high school. c. 56.4% had a religion. d. 84.6% had living standard above medium. e. 89.7% had no occupation. f, 53,8% had previous hospitalization experience. g. 56.4% had previous delivery experience. 3. Examining the importance of 39 nursing activities during puerperal period selected by investigator, studied group of women considered that the most important nursing activity was "Record precisely about condition, medical treatment and nursing activity results etc". Nurses considered that the most important nursing activity was "Notice whether having pain and care for that". Both groups considered that the least important nursing activity was "Talk with her about topics such as news, hobbies, other interests". 4. Examining the importance of nursing activities in 4 specific categories, studied group of women considered that the most important nursing activity in physical nursing category was "Be sure of safety measure to prevent accidents, injuries", and nurses considered that the most important nursing activity was "Make her sleep and rest sufficiently". Studied group of women considered that the most important nursing activity in psychological category was "Explain about medical treatment and nursing activity ahead of time so she knows what to expect" , and nurses considered that the most important nursing activity was "Explain about puerperal period so she understands". Studied group of women considered that the most important nursing activity in relation to medical care was "Record precisely about condition, medical treatment and nursing activity results etc.", and nurses considered that the most important nursing activity was "Observing, cleaning and protecting the perineum" Studied group of women considered that the most important nursing activity in nursing category in preparation for discharge was "Instruct about personnel hygiene during puerperal period", and nurses considered that the most important nursing activity was "Instruct self-care to protect the perineum". 5. The analysis of this study showed a significant amount of disagreement computed by subtracting the nurse′s score from the patient′s score. Studied group of women put greater importance on physical nursing category, psychological nursing category, nursing in relation to medical care, than the nurses. These results were statistically significant at 0.01 level.

It has been forty years since the implementation of National Health Insurance (NHI) in South Korea. Following the 1977 legislature mandating medical insurance for employees and dependents in firms with more than 500 employees, South Korea expanded its health insurance to urban residents in 1989. Resultantly, total expenses of the National Health Insurance Service (NHIS) have greatly increased from 4.5 billion won in 1977 to 50.89 trillion won in 2016. With multiple insurers merging into the NHI system in 2000, a single-payer healthcare system emerged, along with separation policy of prescribing and dispensing. Following such reform, an emerging financial crisis required injections from the National Health Promotion Fund. Forty years following the introduction of the NHI system, both praise and criticism have been drawn. In just 12 years, the NHI achieved the fastest health population coverage in the world. Current medical expenditure is not high relative to the rest of the Organization for Economic Cooperation and Development. The quality of acute care in Korea is one of the best in the world. There is no sign of delayed diagnosis and/or treatment for most diseases. However, the NHI has been under-insured, requiring high-levels of out-of-pocket money from patients and often causing catastrophic medical expenses. Furthermore, the current environmental circumstances of the NHI are threatening its sustainability. Low birth rate decline, as well as slow economic growth, will make sustainment of the current healthcare system difficult in the near future. An aging population will increase the amount of medical expenditure required, especially with the baby-boomer generation of those born between 1955 and 1965. Meanwhile, there is always the problem of unification for the Korean Peninsula, and what role the health insurance system will have to play when it occurs. In the presidential election, health insurance is a main issue; however, there is greater focus on expansion and expenditure than revenue. Many aspects of Korea's NHI system (1977) were modeled after the German (1883) and Japanese (1922) systems. Such systems were created during an era where infections disease control was most urgent and thus, in the current non-communicable disease (NCD) era, must be redesigned. The Korean system, which is already forty years old, must be redesigned completely. Although health insurance benefit expansion is necessary, financial measures, as well as moral hazard control measures, must also be considered. Ultimately, there are three aspects that we must consider when attempting redesign of the system. First, the health security system must be reformed. NHI and Medical Aid must be amalgamated into one system for increased effectiveness and efficiency of the system. Within the single insurer system of the NHI must be an internal market for maximum efficiency. The NHIS must be separated into regions so that regional organizers have greater responsibility over their actions. Although insurance must continue to be imposed nationally, risk-adjustment must be distributed regionally and assessed by different regional systems. Second, as a solution for the decreasing flow of insurance revenue, low premium level must be increased to an appropriate level. Likewise, the national reserve fund (No. 36, National Health Insurance Act) must be enlarged for re-unification preparation. Third, there must be revolutionary reform of benefit package. The current system built a focus on communicable diseases which is inappropriate in this NCD era. Medical benefits must not be one-time events but provide chronic disease management. Chronic care models, accountable care organization, patient-centered medical homes, and other systems that introduce various benefit packages for beneficiaries must be implemented. The reimbursement system of medical costs should be introduced to various systems for different types of care, as is the case with part C (Medicare Advantage Program) of America's Medicare system that substitutes part A and part B. Pay for performance must be expanded so that there is not only improvement in quality of care but also medical costs. Moreover, beneficiaries of the NHI system must be aware of the amount of their expenditure through a deductible payment system so that spending can be profiled and monitored. The Moon Jae-in Government has announced its plans to expand the NHI system; however, it is important that a discussion forum is created so that more accurate analysis of the NHI, its environments, and current status of health care system, can take place for reforming NHI.

만성 폐쇄성 폐질환(COPD)의 병태생리에 산화제와 항산화제간의 불균형이 관여하는 것으로 알려져 있으나 COPD에서 흡연으로 인한 산화제나 항산화제의 변화에 대한 연구는 많지 않다. 저자는 안정상태의 COPD 34명과 정상 대조군 30명을 대상으로 고성능 액체 크로마토그래프를 이용하여 혈청 및 유도객담에서의 항산화제들을 측정하였고, 혈청에서 산화스트레스의 지표로 지질과산화산물을 함께 측정하였다. 혈청 아스코르빈산의 농도는 COPD군에서 정상대조군에 비해 유의하게 감소되어 있었다($484.8{\pm}473.3$ vs $1497.8{\pm}819.2\;pmol/L$, p<0.001). 혈청 알파 토코페롤과 레티놀의 농도도 COPD군에서 대조군에 비해 유의하게 감소되어 있었다(각각 $48.38{\pm}17.34$ vs $73.96{\pm}26.29\;pmol/L$, p<0.001, $9.51{\pm}8.33$ vs $15.01{\pm}5.88\;pmol/L$, p<0.05). 유도객담에서의 항산화제 농도는 양군간에 유의한 차이를 보이지 않았으나, 아스코르빈산의 객담/혈청 비는 COPD군에서 정상인에 비해 유의하게 높았다 (0.375 vs 0.085, p<0.05). 정상인만을 대상으로 했을 때 흡연자에서 혈청 아스코르빈산의 농도가 비흡연자에 비해 유의하게 낮았으나($1073{\pm}536$ vs $1757{\pm}845\;pmol/L$, p<0.05) COPD 환자에 비해서는 여전히 유의하게 높았다 (p<0.05). COPD 환자에서 혈청 레티놀의 농도는 $FEV_1$에 비례하여 증가하였다(r=0.58, p<0.05). 그러나 흡연자들을 대상으로 지질과산화도를 측정한 결과 정상인과 COPD 환자간에 유의한 차이를 보이지 않았다($115.56{\pm}19.93$ vs $120.02{\pm}24.56\;{\mu}mol/{\mu}mol$ Pi of liposome). 혈청에서 항산화제들의 농도가 COPD 환자와 정상 흡연자에서 감소된다는 사실은 흡연 등의 산화 스트레스로 인해 항산화제의 농도가 감소되고 COPD의 병인에도 중요한 역할을 할 것임을 시사한다. 언에도 중요한 역할을 할 것임을 시사한다.

Virtual community(VC) will increasingly be organized as commercial enterprises, with the objective of earning an attractive financial return by providing members with valuable resources and environment. For example, Cyworld.com in Korea uses several community services to enable customers of Cyworld to take control of their own value as potential purchasers of products and services. Although initial adoption is important for online network service success, it does not necessarily result in the desired managerial performance unless the initial usage is continuously related to the continuous usage and purchase. Particularly, the customer who receives relevant online services and is well equipped with online network services, will trust the online service provider and perceive less risk and experience more activities such as continuous usage and purchase. Thus, how to promote continued online service usage or, alternatively, how to prevent discontinuance is a critical issue for VC service providers to consider. By aggregating a wide range of information and online environments for customers and providing trust to its members, the service providers of virtual communities help to reduce the perceived risk of continuous usage and purchase. Drill down, online service managers realize that achieving strong and sustained customers who continuously use online service and purchase on it is crucial. Therefore, the research into this online service continuance will identify the relationship between the initial usage and the continuous usage and purchase. The research of continuous usage or post adoption has recently emerged as an important issue in the IS literature. Individuals' information systems(IS) continuous usage decisions are congruent with consumers' repeat purchase decisions. The TAM(Technology Acceptance Model) paradigm has been strongly confirmed across a wide range from product purchase on EC to online service usage contexts. The analysis of IS usage based on TAM has proven to be successful across almost online service contexts. However, most of previous studies have focused on only an area (i.e., VC or EC). Just little research has tried to analyze the relationship between VC and EC. The effect of some factors on user intention, captured through several theories such as TAM, has been demonstrated. Yet, few studies have explored the salient relationships of VC users' EC acceptance. To fill this gap between VC and EC research, this paper attempts to develop a research model that extends the TAM perspective in view of the additional contributions of trust in the service provider and trust in members on some factors that affect EC and VC adoption. In this extension, we applied the TAM-to-TAM(T2T) model, and analyzed the transfer effect of trust between these two TAMs. The research model was empirically tested on the context of a social network service. The model was to extend TAM with the trust concept for the virtual community environment from the perspective of tasks. By building an extended model of TAM and examining the relationships between trust and the existing variables of TAM, it is aimed to explain a user's continuous intention to use VC and purchase on EC. The unit of analysis in this paper is an individual user of a virtual community. The population of interest is the individual with the experiences in virtual community. The data for this paper was made available via a Web survey of VC users. In total, 281 cases were gathered for about one week, but there were some missing values in the sample and there were some inappropriate cases. Thus, only 248 cases were finally analyzed. We chose the structural equation analysis to test the hypotheses and it is better suited for explaining complex relationships than the other methods. In this test, AMOS was used to test the Structural Equation Model (SEM). Noticeable results have been found in the T2T model regarding the factors affecting the intention to use of virtual community and loyalty. Our result showed that trust transfer plays a key role in forming the two adoption beliefs. Overall, this study preliminarily confirms the salience of trust transfer in online service.

과다한 음주는 알츠하이머 및 파킨슨 질병과 같은 각종 만성 퇴행성 뇌질환의 대표적인 원인 중 하나로 알려져 있다. 체내에 유입된 에탄올은 알코올 탈수소효소(alcohol dehydrogenase, ADH)에 의해 아세트알데히드로 대사된 후 다시 알데히드탈수소효소 2(aldehyde dehydrogenase 2, ALDH2)에 의해 아세트산으로 대사되어 배출된다. 에탄올의 대사과정 중에는 다량의 free radical이 생성되어 체내에서 산화적 스트레스를 유발하는 것으로 알려져 있고, 아세트알데히드는 활성산소를 생산하는 독성물질로 잘 알려져 있다. 본 연구에서는 8주간 에탄올에 노출된 Aldh2 knockout 마우스를 사용하여 ALDH2 효소 활성이 뇌 조직과 소변의 지질과산화에 미치는 영향에 대하여 살펴보았으며, 지질과산화 정도를 측정하기 위해 HPLC를 통한 TBARS 정도를 측정하였다. 연구결과, 마우스에서 만성 에탄올 섭취는 뇌 조직 TBARS 생성에 영향을 주지 않는 것으로 나타났으나, 소변 TBARS는 Aldh2 (-/-) 마우스에서 에탄올을 투여함에 따라 유의한 증가를 보였다(p<0.05). 본 연구 결과로부터 8주간 에탄올을 경구 투여한 마우스에서 ALDH2의 활성은 체내의 전반적인 활성산소 생성에는 중요하게 관여하는 것으로 보이지만 뇌조직에서의 활성산소 생성에는 영향을 주지 않는 것으로 보이며, 이는 에탄올 노출과 이에 따른 활성산소가 다양한 만성 뇌질환을 유발한다는 기존의 가설에서 ALDH2의 활성이 중요하게 관여하지 않을 가능성을 시사한다.

미국 수학계는 하버드대학이 근대수학 교과과정을 도입 한 후 280여년(1640년)이 지나고, 미국수학회(AMS; American Mathematical Society) 창립 후 30년(1890년 뉴욕수학회, 1894년 미국수학회)이 지난 1920년대에도 아직 열악한 연구 여건을 가지고 있었다. 본 연구에서는 미국수학계에 국가연구위원회(National Research Council, NRC)를 통하여 수학분야에 최초로 박사후연구원을 지원하는 제도를 만들고, 기금을 조성하여 프린스턴대학에 당시 세계 최고수준의 수학과 건물인 파인 홀(Fine Hall)을 건축했으며, 1932년 새로 생긴 프린스턴 고등연구소(IAS)에 A. 아인스타인(Einstein), 폰 노이만(von Neumann)등을 초빙하고, Math Review 창간에 결정적인 기여를 하며 미국에서도 수학자가 순수수학 연구의 경쟁력을 확보할 수 있다는 것을 보여준 미국 초창기 수학자 O. 베블런(Osward Veblen)에 대하여 분석한다. 20세기 초반 대부분의 시간을 식민지 상태에서 보낸 한국은 20세기 후반에 회원들의 적극적인 학술활동에 힘입어 2008년 현재 국제수학연맹(IMU)의 5그룹(투표 수를 뜻함) 중에 4 그룹에 속하게 되었다. 더구나 2014년 국제수학자대회(ICM)를 서울에서 유치하게 되었다. 한국이 21세기를 한국 수학의 빠른 발전기로 만들 가능성은 어디에서 찾을 수 있을까? 이에 대한 긍정적인 답을 수학 후진국이었던 미국이 1876년 J. 실베스터를 초빙하여 연구 수준의 수학교육을 최초로 시작한 후 궁극적으로 시카고대학의 E. H. 무어(Moore)가 미국수학회장으로 리더쉽을 발휘한 1900년부터 단 100여년 만에 세계 수학 정상에 자리한 미국수학과 미국수학회의 예를 검증하여 찾아보고자 한다. E. H. 무어가 배출한 인재와 제시한 비전은 E. H. 무어의 제자, L. E. 딕슨(Dickson), O. 베블런, R. L. 무어와 G. D. 버코프(Birkhoff)를 통하여 미국에 구현되었다. 그 중 O. 베블런은 'Princeton algebraic topology' 그룹을 리드하며 미국수학 전반에 세계적인 연구여건을 조성한 탁월한 행정능력가 이었다. G. D. 버코프의 역할은 수학에 대한 학술적 기여의 비중이 컸다. 이들은 20세기 중반 미국이 세계 수학연구의 주류에 진입하는데 크게 기여하였다([9],[10],[21]). 수학자 베블런은 당대 미국 최고수준의 학술적 경지에 도달하였고 1923년 미국수학회장을 역임하였으며 자신이 미국수학계에 제시한 비전과 통찰력을 실제로 구현한 수학자, 리더, 그리고 창조적인 행정가였다. 본 논문은 수학자 베블런이 미국수학계에 끼친 전반적인 영향을 연구하고, 이를 통하여 미국 수학에 실질적인 경쟁력을 부여하며 미국을 세계 수학의 주류에 진입시킨 초창기 미국 수학계 리더의 역할에 대하여 생각해 본다. 본 연구는 근대수학 교과과정 도입 110여년, 2007년 대한수학회 창립 60년을 맞으며 최근 20년간 커다란 발전을 이루어 양적인 면에서는 2007년 세계 12위로 평가된 한국의 다음 단계로의 발전에 대한 논지를 제공하고, 실제로 한국이 세계 수학의 주류로 진입하는데 필요한 구체적인 할 일(Action plan)이 무엇인지를 보여준다. 이는 빠른 변화가 진행되고 있는 국내 과학기술계의 흐름에서 수동적인 추종이 아니라 수학계 스스로 연구-교육-봉사에 균형 잡힌 비전을 제시하고 추구하는 긍정적인 모델을 제시한다.

The purpose of this study was to analyse the problems of 'Science Inquiry Experiment Contest(SIEC)' which was one of 8 programs of 'The 2nd Student Science Inquiry Olympic Meet(SSIOM)'. The results and conclusions of this study were as follows: 1. It needs to reconsider the role of practical work within science experiment because practical work skills form one of the mainstays in current science. But the assessment of students' laboratory skills in the contest was made little account of. It is necessary to remind of what it means to be 'good at science'. There are two aspects: knowing and doing. Both are important and, in certain respects, quite distinct. Doing science is more of a craft activity, relying more on craft skill and tacit knowledge than on the conscious application of explicit knowledge. Doing science is also divided into two aspects, 'process' and 'skill' by many science educators. 2. The report's and checklist's assessment items were overlapped. Therefore it was suggested that the checklist assessment items were set limit to the students' acts which can't be found in reports. It is important to identify those activities which produce a permanent assessable product, and those which do not. Skills connected with recording and reporting are likely to produce permanent evidence which can be evaluated after the experiment. Those connected with manipulative skills involving processes are more ephemeral and need to be assessed as they occur. The division of student's experimental skills will contribute to the accurate assess of student's scientific inquiry experimental ability. 3. There was a wide difference among the scores of one participant recorded by three evaluators. This means that there was no concrete discussion among the evaluators before the contest. Despite the items of the checklists were set by preparers of the contest experiments, the concrete discussions before the contest were necessary because students' experimental acts were very diverse. There is a variety of scientific skills. So it is necessary to assess the performance of individual students in a range of skills. But the most of the difficulties in the assessment of skills arise from the interaction between measurement and the use. To overcome the difficulties, not only must the mark needed for each skill be recorded, something which all examination groups obviously need, but also a description of the work that the student did when the skill was assessed must also be given, and not all groups need this. Fuller details must also be available for the purposes of moderation. This is a requirement for all students that there must be provision for samples of any end-product or other tangible form of evidence of candidates' work to be submitted for inspection. This is rather important if one is to be as fair as possible to students because, not only can this work be made available to moderators if necessary, but also it can be used to help in arriving at common standards among several evaluators, and in ensuring consistent standards from one evaluator over the assessment period. This need arises because there are problems associated with assessing different students on the same skill in different activities. 4. Most of the students' reports were assessed intuitively by the evaluators despite the assessment items were established concretely by preparers of the experiment. This result means that the evaluators were new to grasp the essence of the established assessment items of the experiment report and that the students' assessment scores were short of objectivity. Lastly, there are suggestions from the results and the conclusions. The students' experimental acts which were difficult to observe because they occur in a flash and which can be easily imitated should be excluded from the assessment items. Evaluators are likely to miss the time to observe the acts, and the students who are assessed later have more opportunity to practise the skill which is being assessed. It is necessary to be aware of these problems and try to reduce their influence or remove them. The skills and processes analysis has made a very useful checklist for scientific inquiry experiment assessment. But in itself it is of little value. It must be seen alongside the other vital attributes needed in the making of a good scientist, the affective aspects of commitment and confidence, the personal insights which come both through formal and informal learning, and the tacit knowledge that comes through experience, both structured and acquired in play. These four aspects must be continually interacting, in a flexible and individualistic way, throughout the scientific education of students. An increasing ability to be good at science, to be good at doing investigational practical work, will be gained through continually, successively, but often unpredictably, developing more experience, developing more insights, developing more skills, and producing more confidence and commitment.

선진국들은 종자산업을 국가 신성장 동력산업으로 설정하여 정부차원의 지원을 강화하고 있으며, 글로벌 종자기업은 세계의 종자시장을 선점하기 위하여 종자개발분야에 막대한 예산을 투자하고 있으며, 우리나라도 2000년대 후반 들어 국내종자산업 발전을 위한 정책 추진을 통해 종자산업 육성을 위한 토대를 형성하고 있다. 본 논문에서는 국내외 종자시장 현황을 살펴보고 이에 따른 GSP사업의 역할에 대한 전망을 통해 GSP 사업 추진의 효율성을 제고해 보고자 한다. 세계 종자산업은 글로벌 거대 기업의 대형화로 인하여 독점체제를 형성하고 있어 상위 10개 종자기업이 전체 시장의 73%를 점유하고 있는 것으로 나타났다. 종자업체의 대형화는 종자선택에 대한 제약으로 인하여 가격상승을 불러일으키는 부작용을 초래할 것으로 보여진다. 국내 종자시장은 농업생산량 감소로 인하여 정체상태가 유지되고 있으며, 전반적인 국내 농업생산량의 축소에 따른 종자수요 감소로 인하여 국내 종자시장 규모의 정체와 업체의 영세성과 채소, 벼등 일부 특정품목에 대한 육종기술은 세계적인 수준이나 양배추, 파프리카 및 사료작물 등 글로벌 품종의 육종기술이 상대적으로 취약하고 국내 종자기업들의 신규 전문인력 채용은 거의 이루어지지 않고 있으며, 대학 등의 종자관련 전문인력 양성에 대한 인프라가 부족하여 우수한 육종 전문가 양성이 미흡한 실정이다. 따라서 종자산업은 농산업의 핵심으로 국가의 기간산업을 지탱하는 원천 산업으로서 국가정책적으로 우선순위가 매우 높은 만큼 미래성장 산업으로 정부의 지속적인 투자가 뒷받침되어야 할 것이다. 이에 대한 일환으로 GSP 사업을 추진을 2012년부터 야심차게 추진하고 있으며, 수출전략형 종자개발(10개 품목)과 수입대체 종자개발(10품목)을 통해 수출과 국내 종자자급율 확보를 목표로 종자관련 기업체와 대학 및 연구소의 우수한 전문인력이 투입되어 종자개발연구에 매진하고 있다. 우리나라 종자산업의 발전을 위해서는 GSP 사업의 우수한 성과가 반드시 도출되어야 할 것이며, 이를 위해서는 품종개발 단계외에 종자 수출에 대한 별도의 지원 프로그램 추진이 필요하다.

Information systems (IS) have become ubiquitous and changed every aspect of how people live their lives. While some IS have been successfully adopted and widely used, others have failed to be adopted and crowded out in spite of remarkable progress in technologies. Both the technology acceptance model (TAM) and the IS Success Model (ISSM), among many others, have contributed to explain the reasons of success as well as failure in IS adoption and usage. While the TAM suggests that intention to use and perceived usefulness lead to actual IS usage, the ISSM indicates that information quality, system quality, and service quality affect IS usage and user satisfaction. Upon literature review, however, we found a significant void in theoretical development and its applications that employ either of the two models, and we raise research questions. First of all, in spite of the causal relationship between intention to use and actual usage, in most previous studies, only intention to use was employed as a dependent variable without overt explaining its relationship with actual usage. Moreover, even in a few studies that employed actual IS usage as a dependent variable, the degree of actual usage was measured based on users' perceptual responses to survey questionnaires. However, the measurement of actual usage based on survey responses might not be 'actual' usage in a strict sense that responders' perception may be distorted due to their selective perceptions or stereotypes. By the same token, the degree of system quality that IS users perceive might not be 'real' quality as well. This study seeks to fill this void by measuring the variables of actual usage and system quality using 'fact' data such as system logs and specifications of users' information and communications technology (ICT) devices. More specifically, we propose an integrated research model that bring together the TAM and the ISSM. The integrated model is composed of both the variables that are to be measured using fact as well as survey data. By employing the integrated model, we expect to reveal the difference between real and perceived degree of system quality, and to investigate the relationship between the perception-based measure of intention to use and the fact-based measure of actual usage. Furthermore, we also aim to add empirical findings on the general research question: what factors influence actual IS usage and how? In order to address the research question and to examine the research model, we selected a mobile campus application (MCA). We collected both fact data and survey data. For fact data, we retrieved them from the system logs such information as menu usage counts, user's device performance, display size, and operating system revision version number. At the same time, we conducted a survey among university students who use an MCA, and collected 180 valid responses. A partial least square (PLS) method was employed to validate our research model. Among nine hypotheses developed, we found five were supported while four were not. In detail, the relationships between (1) perceived system quality and perceived usefulness, (2) perceived system quality and perceived intention to use, (3) perceived usefulness and perceived intention to use, (4) quality of device platform and actual IS usage, and (5) perceived intention to use and actual IS usage were found to be significant. In comparison, the relationships between (1) quality of device platform and perceived system quality, (2) quality of device platform and perceived usefulness, (3) quality of device platform and perceived intention to use, and (4) perceived system quality and actual IS usage were not significant. The results of the study reveal notable differences from those of previous studies. First, although perceived intention to use shows a positive effect on actual IS usage, its explanatory power is very weak ($R^2$=0.064). Second, fact-based system quality (quality of user's device platform) shows a direct impact on actual IS usage without the mediating role of intention to use. Lastly, the relationships between perceived system quality (perception-based system quality) and other constructs show completely different results from those between quality of device platform (fact-based system quality) and other constructs. In the post-hoc analysis, IS users' past behavior was additionally included in the research model to further investigate the cause of such a low explanatory power of actual IS usage. The results show that past IS usage has a strong positive effect on current IS usage while intention to use does not have, implying that IS usage has already become a habitual behavior. This study provides the following several implications. First, we verify that fact-based data (i.e., system logs of real usage records) are more likely to reflect IS users' actual usage than perception-based data. In addition, by identifying the direct impact of quality of device platform on actual IS usage (without any mediating roles of attitude or intention), this study triggers further research on other potential factors that may directly influence actual IS usage. Furthermore, the results of the study provide practical strategic implications that organizations equipped with high-quality systems may directly expect high level of system usage.
