국내에 사용되고 있는 진단용 방사선발생장치는 78,000여대에 이르고 있다. 인체 대상의 진단 목적으로 사용할 때에는 의료법의 적용을 받고, 동물 대상의 진단 목적으로 사용할 때는 수의사법의 적용을 받는다. 그 이외의 목적으로 사용 시에는 원자력안전법의 적용을 받는다. 동일한 방사선발생장치라도 사용목적 및 대상에 따라 적용되는 법제가 달라지며, 다원화된 규정이 적용되는 문제점인 법제의 혼란을 방지하기 위해 법제 내용의 분석 및 비교가 필요하다. 본 연구는 질적 조사로, 원자력안전 법, 의료법, 수의사법과 그 하위 규정에 적용되는 진단용 방사선발생장치 도입에 대한 행정절차, 안전성 검사, 인력 관리, 구역 관리, 행정처분에 관한 내용이다. 원자력안전법 하위규정에서는 진단용 방사선발생장치 도입은 허가개념으로 행정절차가 복잡하고 구비요건이 많다. 사용에 따른 안전성 검사는 방사선안전관리 전 분야에 걸쳐 감사 성격의 정기검사를 받게 된다. 안전관리자 및 종사자에 대해 해마다 법정 정기 교육을 받아야 한다. 방사선관리구역을 지정하는 방사선량률 기준이 다르며 방사선량률 측정 의무가 있다. 법제 위반 시 부과되는 행정처분의 양적 차이가 최대 10배에 이르며 전 분야에 걸쳐 원자력안전법 하위규정 적용 시 방사선안전관리 부담이 가장 크다. 동일한 진단용 방사선발생장치의 사용 목적과 촬영대상에 따라 다르게 적용되고 있는 현행 법 제도 하에서는 사용주체에 따라 방사선 안전관리를 위한 법제 내용의 형평성이 결여되어 있고, 혼란의 우려가 있으므로 진단용 방사선발생장치 이용에 따른 법제의 일원화 또는 표준화 등의 대안이 필요할 것으로 예상된다.

전 세계적으로 구강암의 빈도는 점점 증가 추세이며, 특히 한국인의 있어 혀(tongue)는 구강암이 가장 호발하는 장소이다. 구강암은 발암 단계에서부터 과증식 병소(hyperplastic lesion), 이형성(dysplasia) 및 상피내암(carcinoma in situ) 을 거쳐 악성 암종으로 발전하는 다단계 발암과정을 보이며, 분자 생물학적 변이가 구강암을 진행시킴이 널리 알려져 있다. 또한, 구강암은 일반적으로 암세포의 증식 및 고사(apoptosis)의 억제가 중요한 역할을 하고 있다 알려져 있다. 그리고, Bcl-2 family 는 세포 고사에 주요한 역할을 하고 있음이 알려져 있다. 그러나, 이들과 관련한 구강암 발생과정의 변화에 대해서는 널리 연구된 바가 없다. 본 연구는 백서에서 발암 물질인 4-NQO로 구강암을 유도시키고, 구강암 발생 다단계별로 Bcl-2 family의 mRNA 변화를 RT-PCR을 이용해 살펴보았다. Bcl-2 family는 크게 3군, 즉 1) anti-apoptotic, 2) pro-apoptotic, 그리고 3) BH3 only protein으로 분류할 수 있으며, 본 연구에서 anti-apoptotic molecules인 Bcl-w는 모든 군에서 발현이 감소되었으며, Bcl-2는 발현이 증가 되었다. pro-apoptotic molecules에서는 Bad가 제 3군 (편평세포암종)에서 발현이 증가 되었고, 나머지는 감소하였다. BH-3 only protein에서는 Bmf가 제 2군에서, BBC3가 제 3군에서 발현이 증가하였고, 나머지는 모든 군에서 감소하였다. 결론적으로, 4-NQO로 유도된 백서의 발암단계에서, Bcl-2 family의 mRNA 양상은 다양하게 관찰되었으나, Bad 및 BBC3 mRNA가 제 3군에서, Bmf mRNA가 제 2군에서의 발현이 특별함을 알 수 있어, 다단계 발암과정에서의 구강암을 진단하는데 유용하리라 사료된다.

The successful operation of a product In service depends upon the effective provision of logistic support in order to achieve and maintain the required levels of performance and customer satisfaction. Logistic support encompasses the activities and facilities required to maintain a product (hardware and software) in service. Logistic support covers maintenance, manpower and personnel, training, spares, technical documentation and packaging handling, storage and transportation and support facilities.The cost of logistic support is often a major contributor to the Life Cycle Cost (LCC) of a product and increasingly customers are making purchase decisions based on lifecycle cost rather than initial purchase price alone. Logistic support considerations can therefore have a major impact on product sales by ensuring that the product can be easily maintained at a reasonable cost and that all the necessary facilities have been provided to fully support the product in the field so that it meets the required availability. Quantification of support costs allows the manufacturer to estimate the support cost elements and evaluate possible warranty costs. This reduces risk and allows support costs to be set at competitive rates.Integrated Logistic Support (ILS) is a management method by which all the logistic support services required by a customer can be brought together in a structured way and In harmony with a product. In essence the application of ILS:- causes logistic support considerations to be integrated into product design;- develops logistic support arrangements that are consistently related to the design and to each other;- provides the necessary logistic support at the beginning and during customer use at optimum cost.The method by which ILS achieves much of the above is through the application of Logistic Support Analysis (LSA). This is a series of support analysis tasks that are performed throughout the design process in order to ensure that the product can be supported efficiently In accordance with the requirements of the customer.The successful application of ILS will result in a number of customer and supplier benefits. These should include some or all of the following:- greater product uptime;- fewer product modifications due to supportability deficiencies and hence less supplier rework;- better adherence to production schedules in process plants through reduced maintenance, better support;- lower supplier product costs;- Bower customer support costs;- better visibility of support costs;- reduced product LCC;- a better and more saleable product;- Improved safety;- increased overall customer satisfaction;- increased product purchases;- potential for purchase or upgrade of the product sooner through customer savings on support of current product.ILS should be an integral part of the total management process with an on-going improvement activity using monitoring of achieved performance to tailor existing support and influence future design activities. For many years, ILS was predominantly applied to military procurement, primarily using standards generated by the US Government Department of Defense (DoD). The military standards refer to specialized government infrastructures and are too complex for commercial application. The methods and benefits of ILS, however, have potential for much wider application in commercial and civilian use. The concept of ILS is simple and depends on a structured procedure that assures that logistic aspects are fully considered throughout the design and development phases of a product, in close cooperation with the designers. The ability to effectively support the product is given equal weight to performance and is fully considered in relation to its cost.The application of ILS provides improvements in availability, maintenance support and longterm 3ogistic cost savings. Logistic costs are significant through the life of a system and can often amount to many times the initial purchase cost of the system.This study provides guidance on the minimum activities necessary to Implement effective ILS for a wide range of commercial suppliers. The guide supplements IEC60106-4, Guide on maintainability of equipment Part 4: Section Eight maintenance and maintenance support planning, which emphasizes the maintenance aspects of the support requirements and refers to other existing standards where appropriate. The use of Reliability and Maintainability studies is also mentioned in this study, as R&M is an important interface area to ILS.

INSTRODUCTION Service quality is, unlike goods quality, an abstract and elusive constuct. Service quality and its requirements are not easily understood by consumers, and also present some critical research problems. However, quality is very important to marketers and consumers in that it has many strategic benefits in contributing to profitability of marketing activities and consumers' problem-solving activities. Moreover, despite the phenomenal growth of medical service sector, few researchers have attempted to define and model medical service quality. Especially, little research has focused on the evaluation of medical service quality and patient satisfaction from the perspectives of both the provider and the patient. As competition intensifies and patients are demanding higher quality of medical service, medical service quality and patient satisfaction has emerged as a critical research topic. The major purpose of this article is to explore the concept of medical service quality and its evaluation from both nurse and patient perspectives. This article attempts to achieve its purpose by (1)classfying critical service attibutes into threecategories(satisfiers, hygiene factors, and performance factors). (2)measuring the relative importance of need criteria, (3)evaluating SERVPERF model and SERVQUAL model in medical service sector, and (4)identifying the relationship between perceived quality and overall patient satisfaction. METHOD Data were gathered from a sample of 217 patients and 179 nurses in Seoul-area general hospitals. From the review of previous literature, 50 survey items representing various facets of the medical service quality were developed to form a questionnaire. A five-point scale ranging from "Strongly Agree"(5) to "Strongly Disagree"(1) accompanied each statement(expectation statements, perception statements, and importance statements). To measure overall satisfaction, a seven-point scale was used, ranging from "Very Satisfied"(7) to "Very Dissatisfied"(1) with no verbal labels for scale points 2 through 6 RESULTS In explaining the relationship between perceived performance and overall satisfaction, only 31 variables out of original 50 survey items were proven to be statistically significant. Hence, a penalty-reward analysis was performed on theses 31 critical attributes to find out 17 satisfiers, 8 hygiene factors, and 4 performance factors in patient perspective. The role(category) of each service quality attribute in relation to patient satisfaction was com pared across two groups, that is, patients and nurses. They were little overlapped, suggesting that two groups had different sets of 'perceived quality' attributes. Principal components factor analyses of the patients' and nurses' responses were performed to identify the underlying dimensions for the set of performance(experience) statements. 28 variables were analyzed by using a varimax rotation after deleting three obscure variables. The number of factors to be extracted was determined by evaluating the eigenvalue scores. Six factors wereextracted, accounting for 57.1% of the total variance. Reliability analysis was performed to refine the factors further. Using coefficient alpha, scores of .84 to .65 were obtained. Individual-item analysis indicated that all statements in each of the factors should remain. On 26 attributes of 31 critical service quality attributes, there were gaps between actual patient's importance of need criteria and nurse perceptions of them. Those critical attributes could be classified into four categories based on the relative importance of need criteria and perceived performance from the perspective of patient. This analysis is useful in developing strategic plans for performance improvement. (1) top priorities(high importance and low performance) (in this study)- more health-related information -accuracy in billing - quality of food - appointments at my convenience - information about tests and treatments - prompt service of business office -adequacy of accommodations(elevators, etc) (2) current strengths(high importance and high performance) (3)unnecessary strengths(low importance and high performance) (4) low priorities(low importance and low performance) While 26 service quality attributes of SERPERF model were significantly related to patient satisfation, only 13 attributes of SERVQUAL model were significantly related. This result suggested that only experience-based norms(SERVPERF model) were more appropriate than expectations to serve as a benchmark against which service experiences were compared(SERVQUAL model). However, it must be noted that the degree of association to overall satisfaction was not consistent. There were some gaps between nurse percetions and patient perception of medical service performance. From the patient's viewpoint, "personal likability", "technical skill/trust", and "cares about me" were most significant positioning factors that contributed patient satisfaction. DISCUSSION This study shows that there are inconsistencies between nurse perceptions and patient perceptions of medical service attributes. Also, for service quality improvement, it is most important for nurses to understand what satisfiers, hygiene factors, and performance factors are through two-way communications. Patient satisfaction should be measured, and problems identified should be resolved for survival in intense competitive market conditions. Hence, patient satisfaction monitoring is now becoming a standard marketing tool for healthcare providers and its role is expected to increase.

WTO출범 이후 저에너지 소모, 저공해, 무공해 등의 환경친화적 운송수단의 발달이 요구됨과 동시에 세계적으로 고속전철기술의 지속적 발전과 시장 확대가 전망됨에 따라 프랑스, 독일, 일본 등과 같은 철도선진국들은 철도기술 개발에 막대한 기술 투자비를 투입하여 기술 우위를 유지하기 위해 노력을 경주하고 있다. 이러한 기술환경 변화에 적극적으로 대응함과 동시에 좁은 국토에서 도로정체에 의한 물류비 증가와 환경오염, 국민생활의 불편 등으로 인한 사회ㆍ경제적 손실을 최대한 억제하고, 국가경쟁력 제고와 환경친화적인 철도 발전을 이끌기 위해 고속전철기술에 대한 독자적 개발 능력은 절실히 요구되고 있다. 이와 같은 요구에 의해 1996년부터 2002년까지 6년간 수행된 G7 고속전철기술개발사업은 350km/h급 고속전철의 독자적인 설계, 엔지니어링 및 제작 능력을 배양하고, 2000년대 차세대 한국형 고속전철을 실현하기 위한 연구개발 프로그램이다. 본 고에서는 G7 고속전철기술개발사업에서 수행된 연구내용 중 차량시스템 엔지니어링기술개발과제의 디자인부문 개발 성과를 요약 소개하였다. 철도선진국에서는 차량설계 초창기부터 디자인 측면의 검토가 매우 활발히 이루어지고 있는 반면, 국내 철도차량개발에 있어 디자인 측면의 검토는 미비하고 소홀히 다루어지고 있는 것이 현실이었다. 하지만 본 사업에서는 차량개념설계 단계부터 디자인전문가들의 적극적인 참여를 통해 국내 철도차량디자인 개발의 새로운 전기를 마련하였을 뿐만 아니라 새로운 차량디자인의 수요에 능동적으로 대처할 수 있는 기반을 구축하였다. 한국형 고속전철시스템의 디자인 컨셉은 한국의 자연조건과 기술환경에 적합한 보다 빠르고, 보다 쾌적하고, 보다 조용한 한국 고유형 고속전철과 그 여행문화를 이루어내는 것이다. 고속전철의 한국 고유성이란 주로 승객의 고속전철여행을 통해서 인식되어지는 것이다. 따라서 우선적으로 한국의 행동양식과 생활문화를 고려한 일반 객실의 단면개념을 기준으로 공기역학적으로 유리한 단면 외형 형상을 구현하는 한편, 터널 개활지 주행 최적화를 위한 전두부 공력형상 구현, 차체 단면적 축소와 곡선화를 통한 공력저항 최소화, 인간공학적 실내 설계 및 부속실의 편의성 도모, 외관통합 색채디자인 등을 통해 한국 고유형 고속전철 차량 디자인을 개발하였다.

한국 인터넷 정보센터의 인터넷 이용 실태 조사에 의하면 2000년 11월 현재 조사 대상 어린이의 96.9%가 인터넷을 이용한 경험이 있으며, 특히 어린이가 대답한 인터넷의 필요성 항목 1순위는 '숙제해결을 위한 학습' (83.9％)인 것으로 나타났다. 조사 결과에서 보듯이 현실적으로 학습 사이트 중에서도 숙제 도우미 영역의 필요성이 큰 만큼, 교육 컨텐츠 영역의 사업성에서도 간과해서는 안 될 중요한 영역이나 실제 깊이 있는 연구가 이루어지지 못하고 있는 실정이다. 온라인 학습 환경에서 사용자가 정보를 탐색하고 학습내용을 선택하는 행위는 사용자와 컴퓨터간의 지속적인 상호작용에 기반 한다. 이처럼 상호작용을 가능하게 하는 인터페이스 중에서 그래픽 메타포를 이용한 사용자 인터페이스는 현재 많이 사용되고 있으며, 특히 어린이를 대상으로 한 사이트들에서 많은 부분을 차지하고 있다. 그러나 이와 같은 메타포의 활용성에 비해 인터페이스로서의 그래픽 메타포에 대한 구체적인 연구가 부족한 상황이며, 초등학생 대상 사이트의 경우 저학년과 고학년의 인지발달 상황에 따라 메타포를 인지하는 정도가 다름에도 불구하고 아직까지 전 학년에게 공통의 인터페이스가 적용되고 있는 실정이고, 심한 경우 유아와 동일한 인터페이스를 적용한 사이트도 아무 문제제기 없이 운영되고 있다. 이에 본 연구는 어린이대상 사이트에서 그래픽 메타포 인터페이스의 활용 실태를 숙제 도우미 영역을 중심으로 분석하고 사용자 설문조사와 전문가의 휴리스틱 평가를 비교하여 결과를 도출하였다. 조사결과 타겟층의 세분화가 이루어지지 않아 사용자의 욕구에 부응하지 못하고 있는 점과 그래픽 메타포의 기능성이 해외사이트에 비해 현저히 떨어지는 점등이 문제점으로 나타났다. 이와 같은 연구 결과가 인터넷 이용이 보편화하면서 급속히 성장하고 있는 웹을 기반으로 한 학습 시장에서 어린이를 대상으로 하는 웹사이트의 디자인과 제작에 있어서 효과적인 인터페이스 전략을 세우는 근거로 이용되었으면 한다.

Measuring Information Technology(IT) organizations' activities have been limited to mainly measure financial indicators for a long time. However, according to the multifarious functions of Information System, a number of researches have been done for the new trends on measurement methodologies that come with financial measurement as well as new measurement methods. Especially, the researches on IT Balanced Scorecard(BSC), concept from BSC measuring IT activities have been done as well in recent years. BSC provides more advantages than only integration of non-financial measures in a performance measurement system. The core of BSC rests on the cause-and-effect relationships between measures to allow prediction of value chain performance measures to allow prediction of value chain performance measures, communication, and realization of the corporate strategy and incentive controlled actions. More recently, BSC proponents have focused on the need to tie measures together into a causal chain of performance, and to test the validity of these hypothesized effects to guide the development of strategy. Kaplan and Norton[2001] argue that one of the primary benefits of the balanced scorecard is its use in gauging the success of strategy. Norreklit[2000] insist that the cause-and-effect chain is central to the balanced scorecard. The cause-and-effect chain is also central to the IT BSC. However, prior researches on relationship between information system and enterprise strategies as well as connection between various IT performance measurement indicators are not so much studied. Ittner et al.[2003] report that 77% of all surveyed companies with an implemented BSC place no or only little interest on soundly modeled cause-and-effect relationships despite of the importance of cause-and-effect chains as an integral part of BSC. This shortcoming can be explained with one theoretical and one practical reason[Blumenberg and Hinz, 2006]. From a theoretical point of view, causalities within the BSC method and their application are only vaguely described by Kaplan and Norton. From a practical consideration, modeling corporate causalities is a complex task due to tedious data acquisition and following reliability maintenance. However, cause-and effect relationships are an essential part of BSCs because they differentiate performance measurement systems like BSCs from simple key performance indicator(KPI) lists. KPI lists present an ad-hoc collection of measures to managers but do not allow for a comprehensive view on corporate performance. Instead, performance measurement system like BSCs tries to model the relationships of the underlying value chain in cause-and-effect relationships. Therefore, to overcome the deficiencies of causal modeling in IT BSC, sound and robust causal modeling approaches are required in theory as well as in practice for offering a solution. The propose of this study is to suggest critical success factors(CSFs) and KPIs for measuring performance for IT organizations and empirically validate the casual relationships between those CSFs. For this purpose, we define four perspectives of BSC for IT organizations according to Van Grembergen's study[2000] as follows. The Future Orientation perspective represents the human and technology resources needed by IT to deliver its services. The Operational Excellence perspective represents the IT processes employed to develop and deliver the applications. The User Orientation perspective represents the user evaluation of IT. The Business Contribution perspective captures the business value of the IT investments. Each of these perspectives has to be translated into corresponding metrics and measures that assess the current situations. This study suggests 12 CSFs for IT BSC based on the previous IT BSC's studies and COBIT 4.1. These CSFs consist of 51 KPIs. We defines the cause-and-effect relationships among BSC CSFs for IT Organizations as follows. The Future Orientation perspective will have positive effects on the Operational Excellence perspective. Then the Operational Excellence perspective will have positive effects on the User Orientation perspective. Finally, the User Orientation perspective will have positive effects on the Business Contribution perspective. This research tests the validity of these hypothesized casual effects and the sub-hypothesized causal relationships. For the purpose, we used the Partial Least Squares approach to Structural Equation Modeling(or PLS Path Modeling) for analyzing multiple IT BSC CSFs. The PLS path modeling has special abilities that make it more appropriate than other techniques, such as multiple regression and LISREL, when analyzing small sample sizes. Recently the use of PLS path modeling has been gaining interests and use among IS researchers in recent years because of its ability to model latent constructs under conditions of nonormality and with small to medium sample sizes(Chin et al., 2003). The empirical results of our study using PLS path modeling show that the casual effects in IT BSC significantly exist partially in our hypotheses.

The current industrial health service is shifting to health improvement business with 1st primary prevention-focused service from secondary and tertiary prevention-focused business, and Oriental medicine can provide such primary prevention-focused service due to the characteristics of its science. In particular, the advanced concept of health improvement can match the science of health care of Oriental medicine. Notably, what is most important in health improvement is our lifestyle, This does not underestimate the socio-environmental factors, which have lessened their importance due to modernism. The approach of Oriental medicine weighs more individuals' lifestyle and health care through self-cultivation. This matches the new model of advanced health business. Oriental medicine is less systemized than Western medicine, but it can provide ample contents that enhance health. If we conceive health-improvement program based on the advantages provided by these two medical systems, this will influence workers to the benefit of their health. Also, health Program needs to define factors that determine individual lives, and to provide information and technologies essential to our lives. The Oriental medicine approach puts more stress on a subject's capabilities than it does on the effect his surrounding environment can have. This needs to be supported theoretically by not only defining the relations between an individual's health state and his lifestyle, but also identifying the degree to which an individual in the industrial work place practices health improvement lifestyle . This is the first step toward initiating health-improvement business . In order to do this, this researcher conducted a survey by taking random samplings from workers, and can draw the following conclusions from it. 1 The sampled group is categorized into', by sender, female 6.6%, and male 93.4%, with males dominant; by marriage status , unmarried 43.9% and married 55.6%, with both similar percentage, and, by age, below 30, 48.4%, between 30 and 39, 27.4%, between 40 and 49, 18.2%, and over 50, 6.0%. The group further is categorized into; by education, middle school or under 1.7%, high school 30.5%, and junior college or higher 65.8% with high school and higher dominant: and by income, below 1.7 million won 24.2%, below 2.4 million won 14.8%, and above 2.4 million 6.3% Still, the group by job is categorized into collegians with 23.9%, office worker with 10.3%, and professionals with 65.8% , and this group does not include workers engaged in production that are needed for this research, but mostly office workers . 2. The subjects selected for this survey show their degree of practicing health-improvement lifestyle at an average of 2.63, health management pattern at 2.64, and health-related awareness at 2.62 The sub-divisions of health-improvement lifestyle show social emotion (2.87), food (2.66). favorite food (2.59), and leisure activities (2.52), in this order for higher points. It further shows health awareness (2.47) and safety awareness (2.40), lower points than those in health management pattern . 3. In the area of using leisure time for health-improvement, males, older people, married, and people with higher income earn higher marks. And, in the area of food management, the older and married earn higher marks . In the area of favorite food management, females, lower-income bracket, and lower-educated show higher degree of practice , while in the area of social emotion management, the older. married, and higher-income bracket show higher marks. In addition, in the area of health awareness, the older, married, and people with higher-income show higher degree of practice. 4. To look at correlation by overall and divisional health-improvement practice degree , this researcher has analyzed the data using Person's correlation coefficient. The lifestyle shows significant correlation with its six sub-divisions, and use of leisure time, food, and health awareness all show significant correlation with their sub-divisions. And. the social emotion and safety awareness show significant correlation with all sub-divisions except favorite food management.

최근 인터넷 비즈니스의 열풍으로 인하여 국내 인터넷 비즈니스 업체의 수와 사업내용은 여느 선진국가에 못지 않게 높은 성장 및 확장을 보여왔다. 하지만 국내에서 사용되고 있는 인터넷 관련 장비의 대부분은 해외에서 생산된 제품이 주를 이루고 있으며, 실제로 1999년 국내 인터넷 관련 장비 시장에서 국내업체가 차지하는 비중은 불과 27%에 지나지 않았다. 이와 같이 선진 해외 제조업체를 필두로 한 해외 업체의 국내 인터넷 시장 잠식이 본격적으로 진행되고 있는 상황에서, 고객의 요구 충족 및 원가 절감을 통한 경쟁우위의 확보는 국내 제조업체가 생존하기 위한 필수적인 사항이 되고 말았다. 본 연구에서는 지난 몇 년 동안 국내 PC서버 시장의 1위 자리를 놓고 해외 업체와 치열한 경쟁을 벌이고 있는 국내 대표적인 PC서버 제조업체를 대상으로 하여, 이 업체의 공급체인상에 존재하는 비효율, 즉 부품발주주기 간격이 다소 긴 점을 발견하고 이를 수정할 경우 공급체인 전반의 보유 재고량과 총비용 측면에서 나타나는 효과를 시뮬레이션을 통해 분석하였다. 기존에 30일이었던 발주주기를 7일로 단축시켜 시뮬레이션한 결과, 공급체인상의 평균 부품 재고량은 현저히 감소하였으며 판매손실의 감소와 더불어 공급체인 전반에 걸친 총비용의 추정값을 낮추는 결과가 나타났다. 비록 평균 완제품 재고량이 소폭 증가하였고 주문 횟수가 증가함에 따라 총주문비용이 증가하기는 하였지만 발주주기의 단축을 통해 얻어진 평균 부품 재고량의 감소와 판매손실의 감소 이득이 이를 충분히 상쇄하여 최종적으로 총비용 추정값이 감소하는 결과를 보여주었다.
