SaaS 클라우드 컴퓨팅에 관한 기존의 연구는 사용자 관점의 연구는 많으나 공급자의 성공전략 에 관한 연구는 상대적으로 부족하다. 본 연구에서는 고객성과와 재무성과를 기반으로 SaaS 클라우 드 서비스 제공기업의 시장 성공요인을 분석하기 위하여 다변량 잠재성장곡선모델(LGCM)을 사용하 여 국내 SaaS 클라우드 서비스 제공기업의 199개 전략사업부서(SBU)에서 수집한 3년간의 종단 기 업데이터를 분석했다. 연구 결과에 따르면 SaaS 클라우드 컴퓨팅의 차별화된 요인은 초기 단계에서 소프트웨어 제공업체의 비즈니스 가치를 크게 향상시키지 않았지만 SaaS 공급업체가 시간이 지나면 서 성장함에 따라 고객과 재무성과의 성장률에 큰 영향을 미쳤다. 이 연구는 학문적으로는 마이클 포 터의 전략이론이 e-비즈니스에도 적합하다는 것을 입증하며, 실무적으로는 SaaS 제공기업이 채택할 수 있는 전략적 포트폴리오에 관한 추가적인 통찰력을 제공한다.

In the SaaS cloud computing research area, there are many studies from the user's point of view, but there is relatively little research on the supplier's success strategy. In this study, we longitudinally investigate the market success of Software-as-a-Service (SaaS) providers based on customer growth and financial performance. Using a multivariate latent growth curve model (LGCM), we analyzed longitudinal corporate data gathered from 199 strategic business units (SBUs) of SaaS cloud computing providers in Korea for three years. Our results indicate that SaaS cloud computing idiosyncratic factors did not significantly enhance the software providers’ business values in the early stage, but did significantly affect the growth rate of their customer base and financial performance as the software providers became more mature over time. This study presents additional insights for academia and practitioners.

성폭력 피해자의 피해자다움은 성폭력 사건과 피해자에 대한 사람들의 태도 및 판단에 영향을 줄 수 있음에도 불구하고 현재까지 국내에서 체계적인 연구가 수행되지 않았다. 본 연구는 대학생 175명으로부터 수집된 자료에 다차원척도법 모형 중 개인차척도법과 다차원 펴기를 적용하여 사람들이 피해자다움 평가에 중요하게 고려하는 요인을 파악하였다. 구체적으로 선행연구들을 통하여 도출된 피해자다움 지각과 관련된 요인들(‘피해호소의 적극성’, ‘피해자 고통의 가시성’, ‘옷차림의 단정함’, ‘피해추정 시간’)을 조작하여 제작한 그림 자극을 사용하여 참가자들에게 피해자다움 차원에서의 유사성을 평정하도록 하였다. 그 결과, 참가자들은 ‘피해자 고통의 가시성’을 피해자다움 평가에 중요하게 고려한다고 할 수 있었다. 2차원 공간에 군집화된 그림 자극에 대한 참가자들의 지각을 비교한 결과, 참가자들은 이 군집들이 ‘거짓말하는’ 정도와 ‘차분한’ 정도에서 다르다고 지각하였다. ‘피해자 고통의 가시성’을 반영하는 차원의 중요도는 성별과 성폭력 통념 수준에 따라 다르지 않았다. 피해자다움 평가에 고려되는 네 요인의 중요성 서열을 평정한 자료를 이용한 다차원 펴기 분석에서도 성별에 따른 중요성 차이는 발견하지 못하였으며, 성폭력 통념 수용도가 높은 사람들이 피해자의 옷차림과 밤늦은 외출을 상대적으로 중요하게 고려하는 경향이 있었다. 본 연구는 피해자다움의 평가가 성별과 성폭력 통념 수준에 상관없이 ‘피해자 고통의 가시성’을 고려하여 이루어지며, 이 차원이 피해자의 진실성 의심과 관련되어 있다는 것을 경험적으로 확인한 것에 그 의의가 있다.

Although the perceived victim-likeness of sexual violence victims can affect people’s attitudes and judgments toward sexual assault cases and the victims, little systematic research has been conducted in Korea. This study applied the individual difference scaling (INDSCAL) and multi-dimensional unfolding, types of the multi-dimensional scaling (MDS) models, to data collected from 175 college students to find out factors that people consider significantly in evaluating victim-likeness. Specifically, the authors derived the four factors related to the victim-likeness perception from previous studies (‘whether or not the victim appeal to the violence actively,’ ‘whether or not the victim’s suffering is visible,’ ‘whether or not the victim’s clothing is tidy,’ and ‘estimated time of the violence’) and produced pictures describing the victims by manipulated those factors. The participants rated the similarity of victims in terms of victim-likeness by comparing the two pictures presented in a pair. The result finds that the participants considered whether or not the victim’s suffering is visible to evaluate the victim-likeness. As a result of comparing the perceptions of victims being clustered pictures in the two-dimensional space, the differences were found only in depicting the victim as ‘lying’ and ‘calm.’ Individuals’ weights for the dimension of the visibility of the victim’s suffering did not differ in both gender and the acceptance level of sexual violence myth. The multi-dimensional unfolding analysis using ranking data of the four factors’ importance showed no gender difference. On the other hand, the participants with a higher acceptance of the sexual violence myth showed to consider the clothing and late outing of the victim more significantly. It is meaningful that this study found that, regardless of gender and the level of sexual violence myth, whether or not the victim’s suffering was visible contributed to the evaluation of victim-likeness, and the factor was related to assessing the victims’ credibility.

본 연구에서는 지역사회복지관의 이용자와 제공자를 대상으로 Q방법론을 적용하여 지역사회복지관의 서비스 질에 대한 인식유형과 각 인식유형의 특성을 살펴보았다. 본 연구에서는 세 가지 연구문제를 제기하였는데, 첫 번째 연구문제의 분석결과 사회복지조직에서는 PZB의 5가지 서비스 질 구성차원 이외에 전문성, 지속성, 접근성이 도출되어 영리조직과 다른 서비스 질 구성차원이 있었다. 두 번째 연구문제의 결과로서 제공자와 이용자 모두에게 공감성과 지속성이 지역사회복지관의 서비스 질 구성차원의 공통적인 요소로 나왔다. 반면에 제공자는 전문성을 중시하고 이용자는 접근성과 외형성을 중시하였으므로 이들 제공자와 이용자의 서비스 질 구성차원에 차이가 있었다. 세 번째 연구결과 제공자들은 ‘전문적․공감적․지속적인 프로그램의 중시형’, ‘전문성을 갖춘 공감성․중시형’, ‘서비스의 신속적 반응 중시 형’의 3가지 유형으로 나타났고, 이용자들은 ‘’외형성․프로그램의 지속성 중시 형’, ‘공감성․중시형’, ‘접근성․중시형‘의 3가지 유형으로 구분 되었다. 이러한 연구 결과는 비영리조직의 서비스 질 구성차원에 대한 주관적인 태도 및 인식유형을 고찰해 봄으로써 지역사회복지관의 실정에 맞는 적합한 서비스 질 측정과 개선을 위한 기초자료로서 유용하게 활용 될 수 있을 것이다.

The purpose of the study was to examine cognitive types of quality in service of community welfare centers and characteristics of each cognitive type by applying Q methodology with users and offerers of community welfare centers. As the results, the study could sort them into three kinds of offerer types- ‘Type emphasizing specialized, sympathized and continuous programs’, ‘Type emphasizing sympathy with specialty’ and ‘Type emphasizing a quick reaction in service’- and three kinds of user types- ‘Type emphasizing externality and continuity of program’, ‘Type emphasizing sympathy’ and ‘Type emphasizing approach. The study proposed three kinds of research questions. As the results, there were dimensions of quality in service of only social welfare differing from profit-making organizations since specialty, continuity and approach were induced out of offerer types and user types. Sympathy and continuity were common elements between offerer types and user types in a dimension of quality in service of community welfare centers. On the other hand, offerer types emphasized specialty and user types emphasized approach and externality. Therefore, there were differences in cognitive types about dimension of quality in service between offerers and users. The above results of the study can be usefully utilized as basic data for diverse and systematic endeavor to measure and improve quality in service suitable to real conditions of community welfare centers by increasing understanding about subjective attitudes and characteristics of dimension of quality in service of community welfare centers.

This study aims to emphasize growing importance of the walking trail as a new creative tourism resource and to identify conceptual dimensions of the trail based on the tourism storytelling. For this purpose, this study investigates not only meaningful dimensions of tourism storytelling for Galmaetgill of Busan from the survey, but also the differences in these conceptual dimensions among the visitor type, gender, and interpreter involvement. The results of the study suggest that tourism storytelling is classified into three conceptual dimensions, including communicativeness, sensitivity, and locality. The t-tests show significant differences in communicativeness according to type of visitors and interpreter involvement while there is no significant difference in gender. Future study should develop extended conceptual dimensions by applying to other trails such as Dulregil of Mt. Jiri and Ollehgil of Jeju.

An experiment was carried out to boost the production of tasar crops through application of secondary nutrients. Different combinations of secondary nutrients were prepared and its effect was studied on the yield and quality of leaves of tasar food plant Terminalia tomentosa W & A with 2.4 m ${\times}$ 2.4 m spacing and cocoon characters of tasar silkworm Antheraea mylitta Drury reared on them. Among different combinations of secondary nutrients, foliar application of magnesium sulphate (2%, w/v) and basal application of 3 quintal/ha of calcium carbonate (secondary nutrient combination SM5) was found to be the best in crop improvement. It improves the quantity and quality of leaves as well as the commercial characters of cocoons. As a result, silk production improves. Under this combination, leaf yield increased by 26.55% in comparison to control. Average increase in moisture, total mineral, crude protein and total carbohydrate was 3.26%, 20.84%, 15.39% and 17.85% respectively as compared with control. Further, bio assay studies revealed that average larval weight, E.R.R., cocoon weight, shell weight and silk ratio percent increased by 11.25%, 25.71%, 20.05%, 35.14% and 12.17% respectively over control which indicates that secondary nutrient combination $SM_5$ has significant role in improving the production of tasar crops.

The surface morphology of oil-lubricated surface for hydraulic piston motor is believed to be extremely effective in contact mechanics. adhesion. friction and wear. In order to describe morphology of various rubbed surface on driving condition, the wear test was carried out under different experimental conditions in oil-lubricated system. And fractal descriptors was applied to rubbed surface of hydraulic members with image processing system. These descriptors to analyze surface structure are fractal dimension. Surface fractal dimension can be determined by sum of intensity difference of surface pixel. Morphology of rubbed surface can be effectively obtained by fractal dimension.

We defined Cantor dimensions of a perturbed Cantor set, and investigated a relation between these dimensions and Hausdorff and packing dimensions of a perturbed Cantor set. In this paper, we introduce another expressions of the Cantor dimensions. Using these, we study some informations which can be derived from power equations induced from contraction ratios of a perturbed Cantor set to give its Hausdorff or packing dimension. This application to a deranged Cantor set gives us an estimation of its Hausdorff and packing dimensions, which is a generalization of the Cantor dimension theorem.

GDS (Grating automatic Drawing System), which is automatic design system of metal products called grating, is a system that produces various detailed drawings on the basis of information within a Plan Drawing that represents layout of the gratings such as locations, shapes, directions, etc However, automatically produced drawings by GDS do not fully satisfy the standard of the general dimension marking method used among the layout designers. The lack of this standard quality mainly results from the fact that overlapping among dimension markings appears frequently. To solve the overlapping problem we applied the rule-based expert system. The rules for the expert system are designed based on the expertise of skilled layout designers within the grating production lines.

Information systems quality engineering is one of the most problematic areas in practice and research, and needs cooperative efforts between practice and theory [Glass, 1996]. A model for evaluating the quality of system development process and ensuing success is proposed based on information processing theory of project unit design. A nomological net among a set of quality variables is identified from prior research in the areas of organization science, software engineering, and management information systems. More specifically, system development success was modelled as a function of project complexity, system development modelling environment, user participation, project unit structure, resource availability, and the level of iterative nature of development methodology. Based on the model developed from the information processing theory of project unit design in organization science. appropriate quality metrics for each variable in the proposed model are matched. In this way, a framework of relevant systems development and success quality metrics for controlling systems development processes and ensuing success is proposed. The causal relationships among the constructs in the proposed model are proposed as future empirical research for academicians and as managerial tools for quality managers. The framework and propositions help quality manager to select more parsimonious quality metrics for controlling information systems development processes and project success in an integrated way. Also this model can be utilized for evaluating software quality assurance programmes, which are developed and marketed by many vendors.

First, (1) a definition of religion is offered in order to articulatewhat constitutes a quasi-religion, then the study moves on to (2)identifying one of the dimensions of proper religion inCommmunism, and underline the crucial role of doctrine. By applingthese two theories, it is possible to make some valuable comparisonsbetween Christian religion and communism. It is also argued that (3)eschatology is one of the most essential aspects of the doctrinaldimension not only of a religion proper, Christianity but that of aquasi-religion, Marxism and its inculturated form communism. Myintention is to shed light on how remarkably similar (4) characteristics exist between an atheist ideology, dialecticalmaterialism of communism and theist religion, Christianity. Thesecan be discerned when the researcher scrutinizes their fundamental‘doctrinal’ teachings about the (4.1) conditions of life and humanbeings in the world and (4.2.) the kind of solutions both, a religionproper and a quasi-religion offered to save the world from evil inthe last days, the eschaton of Time. Some selected texts and songsof international and Hungarian communism will be used to showhow they understood (a) crucial issues of life, (b) the role ofbelievers (proletariat or church), and (c) the kind of the solutionsthey offered as a remedy to the issues they identified as problems. All of these will be placed under the framework of “end of times”notion which may be comparable to Christian eschatologicalexpectation of the end of times.

we can save a development cost and time as computer was used in tool and die design of car fields in die manufacture process. Dimension accuracy errors such as springback, springgo, overcrown and twist were reduced product accuracy and caused trouble to assembly each parts of car. In this paper, CADCEUS was used to modify and optimize results of deflection for a tail gate panel of car parts in order to reduce dimension accuracy errors by springback in sheet metal forming. As CADCEUS was used to apply for a tail gate panel, the time for quality to improve was reduced to 30%.

The morphological analysis of wear particle is a very effective means for machine condition monitoring and fault diagnosis. In order to describe morphology of various wear particle, the wear test was carried out under different experimental conditions. And fractal descriptors was applied to boundary and surface of wear particle with image processing system. These descriptors to analyze shape and surface wear particle are shape fractal dimension and surface fractal dimension. The shape fractal dimension can be derived from the boundary profile and surface fractal dimension can be determined by sum of intensity difference of surface pixel. The morphology of wear particles can be effectively obtained by two fractal dimensions.

암반은 서로 다른 입자 및 미소크랙과 같은 미소구조의 개별요소로 구성되어 있다. 이러한 미소구조에 대한 연구는 대심도 지하공간개발과 관련된 지질공학 및 토목공학분야등에 있어서의 관심이 증대되고 있다. 따라서, 단순한 연속체역학에 의한 접근보다는 구성입자들에 대한 역학적성질 및 개별구조요소등이 고려되어야 할 것이다. 그러나, 단순한 유크리드 공간에서 아들 구조를 표현하기는 매우 어렵다. 그래서 Mandelbrot에 의해 자연에 있어서 규칙성이 거의 없는 물체를 정량적으로 표현하기위한 Fractal이론이 개발되었다. 본 연구에는, 크랙의 진전과 응력의 관계를 평가하기위해 미소구조의 기하학적 성질이 Fractal차원에 의해 계산되었다. 암반의 역학적 성질을 평가함에 있어 그 구조의 복잡성을 Fractal이론에 의해 단순화 및 수치화시켜 균질화이론에 적용시키므로서 그 평가를 보다 용이하고 효과적으로 할 수 있다.

Rocks are composed of the discrete elements of microstructures such as different grains and microcracks. The studies of these microstructures are of increasing interest in engineering geology and civil engineering related to construction of a deep under-ground space. Accordingly, instead of a simplified continuum approach, discrete structural elements and mechanical properties of various grains must be accounted. But it is difficult to analyse crack and discontinuity surfaces in Euclidean geometry. So, Mandelbrot( 1983) developed fractal theory to manage irregular body in nature. In this study, geometrical properties of microstructures to estimate a relation between crack propagation and stress were calculated. Then it is shown that fractal theory can be applied to research real mechanical behavior of rocks.

본 연구의 목적은 ‘교육지원청 컨설팅장학’의 운영실태를 Cooper, Fusarelli & Randall(2004)의 4차원 모형을 활용하여분석하는 데 있다. 인터뷰와 참여관찰을 통해 32명의 관계자들을 인터뷰한 결과, 규범적 차원에서는 구성원들은교육지원청 컨설팅장학을 ‘전통적 장학보다는 조금 나은 컨설팅장학이라는 이름의 연수’ 정도로 인식하고 있었다. 구조적 차원에서는 빈약한 정보가 담긴 인력풀을 지원받으며 상명하달식의 전형적인 관료제의 구조로 운영되고있었다. 학교는 지침이라는 강제적 동형화와 경험에서 오는 모방적 동형화의 압력에 순응하며 교육지원청 컨설팅장학을실시하고 있었다. 구성적 차원에서는 전문직은 권력의 최상층으로 지배라는 작용 권력을 사용하여 정책이 빠르게정착되도록 하는데 가장 큰 관심을 두고 있었으며, 업무담당자는 실질적인 컨설팅장학 관리자로서 교육청의 행정적관리 및 요구에 순응하면서도 교사들의 불평과 비난을 최소화하기 위해 형식만 갖추는 경향이 있었다. 컨설턴트는전문성을 갖고 있으나 전문성 신장을 위한 충분한 지원을 받지 못하고 있었으며, 컨설턴티는 권력관계의 최하위층으로컨설턴트의 도움은 수긍하면서도 자발적인 요청으로 인식하지 않기 때문에 수동적인 참여자에 머물렀다. 마지막으로기술적 차원에서는 빈약한 정보를 가진 인력풀과 초점을 맞출 수 없는 상황적 맥락, 피드백 기제의 부족 등 여러가지 문제가 발생하였지만 이것을 확실하게 조정할 수 있는 리더십이나 시스템은 부족했다. 앞으로 규범적 가치의공유를 위한 다양한 방안 마련, 교사의 전문성을 인정하는 교육행정 구조로의 전환과 보편화된 디커플링 예방 전략의마련, 조직학습을 이끌어낼 수 있는 리더십의 확보, 확실한 조정과 통제중심의 시스템 설계 등을 제언하였다.

The purpose of this study is to analyze the implementation process of the Consulting Supervision of ’A’ District Office of Education in Seoul using the Four Dimensional Model by Cooper, Fusarelli & Randall(2004). With the help of 32 participants, in-depth interviews with them, and several observations to the sites, we concluded that the consulting supervision is just a little better than a traditional training program. From normative dimension, rather than recognizing a school or teacher as the subject of professional change, he or she was perceived as the front-line worker in the chained bureaucratic system. In structural dimension, the consulting supervision operated on the structure of typical bureaucracy with a top-down model, served as the tool to secure symbolic legitimacy. The schools showed decoupling to cope with institutional pressure through the strategies of comprise and avoidance although they implemented the supervision, acquiescing in the pressure of isomorphism. In constituentive dimension, the educational supervisors was highly interested in the prompt settlement of the policy through domination. Teachers in charge of the consulting supervision tended to manage it as a mere formality in order to minimize the blame from the other teachers, accommodating themselves to the administrative management and demands of an office of education. Consultants’ verification and management was not systematic. Consultantees, who were situated in the lowest position, remained the passive participants. In technical dimension, the consulting supervision lacked in leadership and system which adjusted the problems of the poor information, the topic selection and the shortage of feedback mechanism. Based on the analyses, several policy implications are suggested.

북한강 수계는 여러 하천을 지류로 갖고 유하하고 있으며 하천의 크기 및 본류의 형상에 따라 다양한 방법으로 지류하천이 합류하고 있으나 기존의 지류하천 홍수위 산정방법은 일률적으로 본류의 계획홍수위를 기점홍수위으로 산정하여 계획하고 있다. 따라서 본 연구에는 다양한 지류하천에 대하여 2차원 수치해석을 이용 합류부 지점의 수면형을 해석함으로써 지류 하천의 기존 기점홍수위 적용방법의 적정성에 대하여 검증하였다. 연구방법은 11개 연구대상 지류 하천에 대하여 유입각, 본류와 지류의 유량비 및 하천폭, 본류의 하천 곡선방법에 대하여 수치해석결과를 비교하였다. 유입각에 따른 수위편차를 검토한 결과, 유입각 $90^{\circ}$이하인 지류하천에서 2차원 수치해석 값이 기존 기점홍수위보다 크게 산정되었다. 본류 하천과 지류 하천과의 유량비를 산정하여 수위편차를 검토한 결과 수치적인 경향은 확인할 수 없었다. 본류 하천과 지류 하천의 하폭비를 산정하여 수위편차를 비교한 결과 하폭비가 7이상인 경우 수위편차가 작고, 기존 기점홍수위보다 2차원 수치해석값이 작게 산정되었으며, 하폭비가 $3^{\sim}6$ 범위에서는 수위편차가 가장 크게 발생하는 것을 확인하였다. 본류 하천의 곡선반경을 수위편차와 비교한 결과 곡선반경이 550m이하인 만곡지점의 경우 수위편차가 크게 발생함을 확인할 수 있었다.
