This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. The specific objectives were: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i)FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the inter-birth interval and/or open interval, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. Study design; The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum 'package' program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and 'before and after' surveys were conducted to measure the change. Service input; This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. Method of evaluation; a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed; b. Nevertheless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the 'integration process' itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltrurture, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable: Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. Summary of Findings; A) Program effects and impact 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 75% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) at delivery care(45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) Effects on Interactive Linkage 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in caring for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However, $85{\sim}90%$ of the services provided by the health workers were other than FP/MCH, mainly for immunizations such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs.31%) and for more combined care (45% vs.23%). C) Organization factors (admistrative integrative issues) 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following ; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub·center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwive's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea); 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through family planning practice. 2) Goal consensus in FP/MCH shouBd be made among the health workers It administrators, especially to emphasize the need of care of 'wanted' child. But there is a long way to go to realize the 'real' integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (in) there should be a health sub·center director who can provide leadership training for managing the integrated program. There is a need for 'organizational support', if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the managment of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Worker, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.

信任在心理学, 经济学, 社会学中已被广泛研究, 其重要性不仅在市场营销中被强调, 在一般商业原则中也被强调. 供应商和买家之间的关系与过去不同, 过去的关系需要相当大的私人网络优势, 并可能涉及不道德的商业行为. 而在以工业营销成功的为核心的二十一世纪激烈的全球竞争中, 供应商和买家之间的关系是伙伴关系. 在相互合作的高级别信任的基础上, 通过交换的关系, 这会给买家和供应商带来长期的利益, 竞争力增强和交易成本的降低以及其他福利. 尽管现有的研究有信任的重要性, 但是在购买与供应关系中却忽视了信任的作用, 也没有系统地分析信任对关系的影响. 因此, 深入研究, 确定买家和商业服务供应商之间信任和关系绩效之间的联系是绝对需要的. 本研究中的商业服务, 包括那些支持制造业, 正作为下一代经济增长的引擎而吸引着人们的注意. 韩国政府已选择其作为制造业发展的战略领域. 由于商业服务开放市场的需求日趋激烈, 商业服务业的竞争力应该比以往得到更多的提倡. 本研究的目的是探索相互信任对买家和供应商之间的关系绩效的影响. 具体来说, 本研究在商业服务交易中提出了一个关于信任-关系绩效的理论模型, 并实证检验根据模型而提出的假设. 这项研究表明, 研究结果有战略意义. 本研究通过多种方法收集经验数据. 这些方法包括通过电话, 邮件和面试. 作为样本的公司是在韩国供应和购买商业服务的以知识为本的公司. 本研究收集的是二进的基础数据. 每个样本公司对包括购买公司及其相应的供应公司. 并跟踪调查每个公司对的相互信任. 本研究为商业服务的买卖双方提出了信任-关系绩效的模型. 该模型由信任和它的前因和后果. 买家的信任分为对供应公司的信任和对销售人员的信任. 根据Doney 和Cannon (1997)的研究我们在个人水平和组织水平上观察信任. 通常情况下, 买方是信任的受体, 但这项研究我们建议以供应商为观察受体. 因此, 它独特的关注了双边角度的知觉风险. 换言之, 供应商和买家一样, 是信任的主体, 因为交易通常是双边的. 从这个角度来看, 供应商对买家信任和买方对供货商的信赖一样重要. 供应商的信任从某种程度上受它信任的买方公司和买家的影响. 这种使用个人水平和组织水平的信任分类是根据Doney 和Cannon (1997)的研究. 信任影响供应商的选择, 这是一项双向放的工作. 供应商们积极参与供应商选择过程中, 和买家密切的一起工作. 此外, 该过程从某种程度上受每一方信任的合作伙伴的影响. 挑选过程包括一些步骤: 识别, 信息检索, 供应商选择和绩效评价. 作为这一进程的结果, 买家和供应商都进行绩效评估, 并就这些结果为基础, 采取有形或无形的纠正行动. 本研究中使用的关于信任的测量问项是根据Mayer, Davis 和 Schoorman (1995) 以及Mayer和Davis (1999)的研究发展起来的. 根据他们的建议, 有关信任的三个方面的研究包括有能力, 善和完整. 根据商业服务这个背景我们调整了原来的问题. 例如, 如 "他/她的专业能力" 已被改为 "当我们讨论我们的产品时销售人员表现出专业能力. "这项研究使用的测量问项不同于在以往的研究中使用的问项（Rotter 1967; Sullivan和Peterson 1982; Dwyer和Oh 1987. 本研究中有关信任的前因后果的测量问项是根据Doney和Cannon (1997)的研究为基础制定的. 根据商业服务这个背景我们调整了原来的问题. 特别是, 问题被设计为对买家和供应商以解决下列因素: 信誉 (诚信, 客户服务, 良好意愿), 市场地位 (公司规模, 市场份额, 在行业中的地位), 愿意定制（产品, 过程, 交付), 信息共享(专有信息, 个人信息), 愿意保持良好关系, 认为专业, 权威授权, 买方与卖方的相似性, 以及接触频率. 作为信任相应的变量, 我们对关系绩效进行了测试. 关系绩效分为有形的影响, 无形影响, 和副作用. 有形的影响包括财务业绩;无形的影响, 包括关系的改善, 网络开发, 以及内部员工的满意度;副作用包括既不是有形影响也不是无形影响的影响. 我们联系了350对公司, 105对公司答复了我们. 由于不完整我们删除了5对公司, 105对公司被用于数据分析. 用于数据分析的回应率为30%(三百五十零分之一百零五), 高于工业营销的平均回复比率. 至于回复的公司的特点, 大多数的公司运作的商业服务既为买方(85.4%)也为供应商(81.8%). 大部分买家是做消费品贸易(76%), 而供应商的大部分(70%)是做工业品贸易. 这可能意味着买家的过程是购入材料, 部件和组件从而生产消费品成品. 正如他们对他们与合作伙伴关系的长度的报告表示, 供应商比买家有更长的商业关系. 假设1测试买方-供应方特点对信任的影响. 销售人员的专业度(t=2.070, p<0.05)和权威授权(t=2.328, p<0.05)积极影响买方对供应方的信任. 另一方面, 权威授权(t=2.192, p<0.05)积极影响供应方对买方的信任. 对买方和供应方来说, 权威授权的程度对保持对彼此的信任有关键作用. 假设2测试买卖双方关系特点对信任的影响. 买家倾向于信任供应方, 因为供应方总是尽全力联系买方(t=2.212, p<0.05)这种倾向性在供应方方面也表现得很强(t=2.591, p<0.01). 另一方面, 供应商对买方的信任是由于供应商感知买家与自己的相似性(t=2.702, p<0.01). 这一发现证实了Crosby, Evans, 和Cowles(1990)的研究结果. 他们的结果表明供应方和买方通过商务或私务的定期会议来建立彼此的联系. 假设3测试信任对感知风险的影响. 结果表明无论对买方还是供应方, 信任越低, 感知风险就越大(买方: t =-6.621, p<0.01; 供应方: t=-2.437, p<0.05). 有趣的是, 这一趋势已被证明对买方更强. 这种较高水平的感知风险的一个可能的解释是在商业服务交易中买方通常比供应方感知到更大的风险. 为此, 有必要对供应商对买方实施减少风险的战略. 假设4测试信任对信息搜集. 根据结果, 对供应方和买方, 与预期相反, 信任取决于他们合作伙伴的名誉(买方t=2.929, p<0.01; 供应方t=2.711, p<0.05). 这一发现表明, 具有良好信誉的供应商往往是可信的. 以往的经验并没有显示出任何与买家或供应商信任的重要关系. 假设5测试信任对供应方/买方选择的影响. 与买方不同, 当供应方认为以往与买方的交易重要时, 供应方倾向信任买方(t=2.913 p<0.01). 但是, 本研究并没有现实资源忠诚和买方对供应方的信任之间有显著关系. 假设6测试的是信任对关系绩效的影响. 对买方和供应方, 当财务表现被报告提高时, 他们比较信任他们的合作伙伴(买方: t=2.301, p<0.05;供应方: t=3.692, p<0.01). 有趣的是, 这种趋势在供应方比较明显. 类似的, 当竞争力被报告提高时, 买卖双方比较信任他们的合作伙伴(买方t=3.563, p<0.01 ; 供应方t=3.042, p<0.01). 对供应方来说, 当对买方信任时效率和生产力会提高(t=2.673, p<0.01). 其他绩效指标与信任没有显著关系. 这项研究结果有一定的战略意义. 首先和最重要的是, 以信任为基础的交易对供应商和买家而言都是有益的. 根据研究证实, 通过努力建立和保持相互信任可以使财务表现提高. 同样, 可以通过同样的努力提高竞争力. 第二, 以信任为基础的交易能够减少购买情况中的感知风险. 这对供应商和买家都有启示. 人们普遍认为, 在一个高度参与的采购情况中买家感知到更高的风险. 为了减少风险, 以往的研究已建议供应商制定降低风险的策略. 而本研究的特点是从双边角度关注知觉风险. 换言之, 供应商也容易存在风险, 特别是当他们提供的服务, 需要非常先进的技术, 操作和维护. 因此, 购买者和供应商必须一起密切合作解决问题. 因此, 相互信任在问题解决过程中起着关键作用. 第三, 在这项研究中发现, 销售人员有更多的授权, 他或她越被信任. 这一发现从战术角度看是非常重要的. 建立信任是一个长期的任务, 然而, 当互信尚未开发, 供应商能够通过授权销售人员做出某些决定来克服遇到的问题, 这一结论也适用于供应商.

The supply chain management (SCM) systems have emerged as strong managerial tools for manufacturing firms in enhancing competitive strength. Despite of large investments in the SCM systems, many companies are not fully realizing the promised benefits from the systems. A review of literature on adoption, implementation and success factor of IOS (inter-organization systems), EDI (electronic data interchange) systems, shows that this issue has been examined from multiple theoretic perspectives. And many researchers have attempted to identify the factors which influence the success of system implementation. However, the existing studies have two drawbacks in revealing the determinants of systems implementation success. First, previous researches raise questions as to the appropriateness of research subjects selected. Most SCM systems are operating in the form of private industrial networks, where the participants of the systems consist of two distinct groups: focus companies and vendors. The focus companies are the primary actors in developing and operating the systems, while vendors are passive participants which are connected to the system in order to supply raw materials and parts to the focus companies. Under the circumstance, there are three ways in selecting the research subjects; focus companies only, vendors only, or two parties grouped together. It is hard to find researches that use the focus companies exclusively as the subjects probably due to the insufficient sample size for statistic analysis. Most researches have been conducted using the data collected from both groups. We argue that the SCM success factors cannot be correctly indentified in this case. The focus companies and the vendors are in different positions in many areas regarding the system implementation: firm size, managerial resources, bargaining power, organizational maturity, and etc. There are no obvious reasons to believe that the success factors of the two groups are identical. Grouping the two groups also raises questions on measuring the system success. The benefits from utilizing the systems may not be commonly distributed to the two groups. One group's benefits might be realized at the expenses of the other group considering the situation where vendors participating in SCM systems are under continuous pressures from the focus companies with respect to prices, quality, and delivery time. Therefore, by combining the system outcomes of both groups we cannot measure the system benefits obtained by each group correctly. Second, the measures of system success adopted in the previous researches have shortcoming in measuring the SCM success. User satisfaction, system utilization, and user attitudes toward the systems are most commonly used success measures in the existing studies. These measures have been developed as proxy variables in the studies of decision support systems (DSS) where the contribution of the systems to the organization performance is very difficult to measure. Unlike the DSS, the SCM systems have more specific goals, such as cost saving, inventory reduction, quality improvement, rapid time, and higher customer service. We maintain that more specific measures can be developed instead of proxy variables in order to measure the system benefits correctly. The purpose of this study is to find the determinants of SCM systems success in the perspective of vendor companies. In developing the research model, we have focused on selecting the success factors appropriate for the vendors through reviewing past researches and on developing more accurate success measures. The variables can be classified into following: technological, organizational, and environmental factors on the basis of TOE (Technology-Organization-Environment) framework. The model consists of three independent variables (competition intensity, top management support, and information system maturity), one mediating variable (collaboration), one moderating variable (government support), and a dependent variable (system success). The systems success measures have been developed to reflect the operational benefits of the SCM systems; improvement in planning and analysis capabilities, faster throughput, cost reduction, task integration, and improved product and customer service. The model has been validated using the survey data collected from 122 vendors participating in the SCM systems in Korea. To test for mediation, one should estimate the hierarchical regression analysis on the collaboration. And moderating effect analysis should estimate the moderated multiple regression, examines the effect of the government support. The result shows that information system maturity and top management support are the most important determinants of SCM system success. Supply chain technologies that standardize data formats and enhance information sharing may be adopted by supply chain leader organization because of the influence of focal company in the private industrial networks in order to streamline transactions and improve inter-organization communication. Specially, the need to develop and sustain an information system maturity will provide the focus and purpose to successfully overcome information system obstacles and resistance to innovation diffusion within the supply chain network organization. The support of top management will help focus efforts toward the realization of inter-organizational benefits and lend credibility to functional managers responsible for its implementation. The active involvement, vision, and direction of high level executives provide the impetus needed to sustain the implementation of SCM. The quality of collaboration relationships also is positively related to outcome variable. Collaboration variable is found to have a mediation effect between on influencing factors and implementation success. Higher levels of inter-organizational collaboration behaviors such as shared planning and flexibility in coordinating activities were found to be strongly linked to the vendors trust in the supply chain network. Government support moderates the effect of the IS maturity, competitive intensity, top management support on collaboration and implementation success of SCM. In general, the vendor companies face substantially greater risks in SCM implementation than the larger companies do because of severe constraints on financial and human resources and limited education on SCM systems. Besides resources, Vendors generally lack computer experience and do not have sufficient internal SCM expertise. For these reasons, government supports may establish requirements for firms doing business with the government or provide incentives to adopt, implementation SCM or practices. Government support provides significant improvements in implementation success of SCM when IS maturity, competitive intensity, top management support and collaboration are low. The environmental characteristic of competition intensity has no direct effect on vendor perspective of SCM system success. But, vendors facing above average competition intensity will have a greater need for changing technology. This suggests that companies trying to implement SCM systems should set up compatible supply chain networks and a high-quality collaboration relationship for implementation and performance.

텍스트를 바탕으로 한 차원 기반 감성 분석(Aspect-Based Sentiment Analysis)은 다양한 산업에서 유용성을 주목을 받고 있다. 기존의 차원 기반 감성 분석에서는 타깃(Target) 혹은 차원(Aspect)만을 고려하여 감성을 분석하는 연구가 대다수였다. 그러나 동일한 타깃 혹은 차원이더라도 감성이 나뉘는 경우, 또는 타깃이 없지만 감성은 존재하는 경우 분석 결과가 정확하지 않다는 한계가 존재한다. 이러한 문제를 해결하기 위한 방법으로 차원과 타깃을 모두 고려한 감성 분석(Target-Aspect-Sentiment Detection, 이하 TASD) 모델이 제안되었다. 그럼에도 불구하고, TASD 기존 모델의 경우 구(Phrase) 간의 관계인 지역적인 문맥을 잘 포착하지 못하고 초기 학습 속도가 느리다는 문제가 있었다. 본 연구는 TASD 분야 내 기존 모델의 한계를 보완하여 분석 성능을 높이고자 하였다. 이러한 연구 목적을 달성하기 위해 기존 모델에 합성곱(Convolution Neural Network) 계층을 더하여 차원-감성 분류 시 보조 손실(Auxiliary loss)을 추가로 사용하였다. 즉, 학습 시에는 합성곱 계층을 통해 지역적인 문맥을 좀 더 잘 포착하도록 하였으며, 학습 후에는 기존 방식대로 차원-감성 분석을 하도록 모델을 설계하였다. 본 모델의 성능을 평가하기 위해 공개 데이터 집합인 SemEval-2015, SemEval-2016을 사용하였으며, 기존 모델 대비 F1 점수가 최대 55% 증가했다. 특히 기존 모델보다 배치(Batch), 에폭(Epoch)이 적을 때 효과적으로 학습한다는 것을 확인할 수 있었다. 본 연구에서 제시된 모델로 더욱 더 세밀한 차원 기반 감성 분석이 가능하다는 점에서, 기업에서 상품 개발 및 마케팅 전략 수립 등에 다양하게 활용할 수 있으며 소비자의 효율적인 구매 의사결정을 도와줄 수 있을 것으로 보인다.

항공안전에 대한 항공선진국의 항공안전정책을 통해 얻을 수 있는 시사점을 위해 미국, 영국, 호주, 일본의 항공안전정책을 살펴보았으며 외국의 저비용항공사의 현황 및 한국의 저비용항공사의 안전정책 및 항공기 사고에 따른 항공안전 현황을 살펴보았다. 기존의 저비용항공사와 이제 신규 저비용항공사가 지역을 기반으로 지역항공사의 개념으로 탄생함으로써 새로운 저비용항공사의 시장이 형성되고 있는 상황이며 인근 동남아 지역에는 말레이시아의 와 같은 안전의 신뢰성을 갖고 정부가 지원하는 저비용항공사가 있는 반면 항공기 사고로 인하여 경영이 악화되었거나 안전성에 대한 신인도가 추락된 저비용항공사가 산재되어 있어서 외국의 저비용항공사에 대한 안전성 검증과 함께 국내 항공사의 국제선 진출에 대비한 신뢰성 향상 및 국제적 안전성 확보를 위한 안전관리 대책이 필요하다. 또한 현재 항공자유화와 항공수요의 다양화로 저비용항공사 증가 추세에 있으며 최근 제주항공, 에어부산, 진에어, 이스타항공이 국내선 운항과 동시에 국제선운항을 시작하였거나 준비하고 있는 상태이다. 본 논문은 최초 저비용항공사 출범 직후의 안전성에 대한 문제를 중심으로 연구를 진행하였으며 이후 이들 항공사 사고가 발생할 개연성에 대한 부분도 고려하였다. 따라서 국내외 항공시장의 환경변화에 능동적으로 대처하고 항공산업의 경쟁력 제고를 위해 신규 저비용항공사의 안전관리의 강화가 그 언제보다 필요한 시기라고 생각된다. 따라서 해외의 항공안전정책 가운데 미연방항공청의 Flight Plan 하위의 Business Plan처럼 구체적인 항공안전계획이 필요하다고 생각되며 본 논문이 저비용항공사의 항공안전 제고 노력에 미력이나마 도움이 되기를 바란다.

전세계의 교육공동체들은 STEM (Science, Technology, Engineering, and Mathematics) 과목들을 통합하려는 노력에 주목해오고 있다. 우리나라에서도 또한 과학기술 인재 양성을 위해 초 중등학교에서 과학기술학, 예술, 수학교육(STEAM)을 융합형으로 가르치는 교육을 강조하고 있다. 이 연구의 목적은 과학, 기술, 수학교사를 대상으로 하여 중등학교에서 이루어지고 있는 통합교육의 현황과 통합 STEM 교육(Integrative STEM Education)에 대한 교사들의 인식과 요구를 분석하는 것이다. 전국 중등교사 중 과학, 수학, 기술 교과를 담당하는 251명을 대상으로 설문조사를 하였으며, 연구 결과는 다음과 같다. 첫째, 교사들은 통합 교육의 필요성에 대하여 긍정적인 생각을 가지고 있는 반면 실제 교육현장에서는 통합 교육 준비에 대한 불충분한 시간과 통합 교육에 대한 전문성, 교수경험 그리고 교수-학습 자료의 부족으로 통합 교육을 실시해 본 횟수는 적었다. 둘째, 그들은 통합 교육을 활성화하기 위하여 다양한 프로그램 개발, 통합 교육 준비를 위한 학교의 행 재정적 지원, 그리고 교사들을 위한 연수 실시 등을 요구하였다. 셋째, 통합 STEM 교육에 대한 인식은 전반적으로 불충분하지만 교사들은 학생들의 창의력, 사고력과 실생활에서의 적용 및 응용력을 기르기 위해 통합 STEM 교육이 필요하다고 인식하였다. 넷째, 교사들은 통합 STEM 교육 프로그램 개발, 교수-학습 자료의 보급을 시급한 과제로 생각하고 있다. 다섯째, 교사들은 통합 STEM 교육 프로그램에 적합한 통합 방식은 문제해결중심의 통합 방식으로 나타났다. 아울러, 통합 STEM 교육이 통합적 문제 해결과 담당 교과의 소양 함양에 효과적이라고 생각하며, 과학기술 인재 양성에 영향을 많이 줄 것이라고 생각하고 있었다. STEM 관련 중등교사들의 통합 STEM 교육에 대한 인식을 높이고, 통합 STEM 교육을 활성화하기 위해서 학교 현장을 중심으로 교사의 요구가 반영된 프로그램, 다양한 교수 학습 자료의 보급, 그리고 관련 연수들이 필요하다.

본 연구는 기업의 혁신전략이 특허생산 및 기업의 기술변화와 신제품개발에 미치는 영향을 분석함으로써 기업의 기술성과를 증대시키는 데 필요한 혁신전략을 도출하고자 하였다. 사용자료는 한국직업능력개발원의 "인적자본기업패널조사"(HCCP)의 1~4차년도 자료와 한국신용평가원의 기업재무자료, 특허청의 기업별 특허출원자료를 결합한 자료이다. 특허생산함수는 영과잉음이항회귀모형(ZINB)을 사용하여 추정하였다. 기업의 기술성과 결정요인은 특허의 내생성을 고려하여 2단계 추정방법을 사용하였고, 2단계 회귀식은 순위로짓모형을 사용하였다. 분석결과, 기업의 혁신전략이 특허생산 및 기업의 기술변화와 신제품개발에 중요한 영향을 미치는 것을 확인할 수 있었다. 첫째, 특허생산에서는 기업의 연구개발투자와 인적자원이 중요한 투입요소로 나타났다. R&D집약도가 높을수록 특허생산이 활발하게 이루어지되 한계 생산은 체감하였고, 기업이 보유하고 있는 특허스톡이 많을수록 신규특허의 생산이 활발하였다. 기업의 인적자원수준이 높고 인적자원투자가 많을수록 특허생산이 활발하였고, 기업이 시장선도전략이나 빠른 추종자전략을 추구할 때 안정형 전략을 구사하는 기업에 비해 특허생산이 많았다. 둘째, 기업의 기술성과 결정요인으로는 인적자원의 역할이 중요하였고, R&D 집약도는 대기업의 신제품개발에 유의한 영향을 미쳤다. 시장선도전략이나 빠른 추종자전략을 택한 기업의 기술성과가 안정형 전략의 기업보다 높았다. 특허생산이 활발한 기업일수록 기술성과가 높으나, 이는 상당부분 특허의 내생성에 기인한다. 본 연구의 분석결과는 특허의 생산뿐 아니라 특허와 신제품개발과 같은 기술성과와의 연계성을 높이는 전략이 필요하며, 기업특성에 따른 차별화 전략이 필요하다는 것을 시사한다.
