소프트웨어 품질 및 신뢰성 확보를 위해서는 체계적인 소프트웨어 개발, 관리 및 조직적인 지원 등이 이루어져야만 한다. 이러한 소프트웨어 프로세스 개선모델로는 ISO/IEC 15504와 CMMI 등의 국제적 모델이 많이 사용되고 있다. 그러나 이러한 국제적 SPI 모델은 대규모의 조직이나 대규모 프로젝트를 적용대상으로 하고 있으며, 수행해야만 하는 활동과 프로세스가 많을 뿐만 아니라 프로세스 심사 또는 인증 시에 비용과 시간이 많이 소요되는 문제점이 있다. 본 논문은 CMMI, ISO/IEC 15504 및 국내 중소기업들이 프로세스 개선에 쉽게 적용가능 하도록 개발한 소프트웨어 프로세스 품질인증 모델인 K-모델의 특징을 서로 비교하고 K-모델을 기반으로 프로세스 심사, 개선 및 인증 시에 필요한 측정 메트릭스를 제시한다. 정량적이고 객관적인 프로세스 측정을 통하여 프로세스 개선이 쉽게 이루어질 수 있으며, 실험을 통하여 메트릭스의 타당성을 분석한다.

In the wake of several high-profile corporate accounting scandals, there has been evidence that companies are more eager to hire Chief Executive Officers (CEOs) with an accounting background. This signals that CEOs with an accounting background are recognized and trusted by the corporate world to boost the quality of financial reporting of a company. If it is so, in the context of combating the earnings management, hiring CEOs with an accounting background (being a conservative accounting practitioner), could become one of the effective internal corporate governance mechanisms (CGM) to bring down the earnings management activities. This study attempts to provide insight into the level of conservatism of the CEO with an accounting background. Following Basu (1997) and Khan and Watt (2009), the firm-year measure of conservatism (C_Score) was obtained, which later was associated with the accounting education of the CEO to determine their relationship. As expected, CEOs with accounting background exhibit a higher level of moral reasoning than their non - accounting educated counterparts. The finding of this study is useful to persuade the policymaker to consider lifting the trend of hiring a CEO with an accounting background as one of the best practices that the companies can work out to lessen earnings management activities.

Reflecting the current international trends toward proactive risk assessment and control at work with practical procedures, participatory action-oriented approaches are gaining importance in various sectors. The roles of these approaches in promoting the safety and health at work are discussed based on their recent experiences in preventing work-related risks and improving the quality of work life, particularly in small-scale workplaces. The emphasis placed on the primary prevention at the initiative of workers and managers is commonly notable. Participatory steps, built on local good practices, can lead to many workplace improvements when the focus is on locally feasible low-cost options in multiple aspects. The design and use of locally adjusted action toolkits play a key role in facilitating these improvements in each local situation. The effectiveness of participatory approaches relying on these toolkits is demonstrated by their spread to many sectors and by various intervention studies. In the local context, networks of trainers are essential in sustaining the improvement activities. With the adequate support of networks of trainers trained in the use of these toolkits, participatory approaches will continue to be the key factor for proactive risk management in various work settings.

Epidemiology and preventive medicine are changing together with Population and health and with ever expanding medical and non medical technologies. New technologies make epidemiology methodologically more sophisticated, but such advances risk overshadowing epidemiology's most important role: raising questions, providing answers, and helping the medical decision-making at ail levels of prevention. Epidemiology also plays a major role in the evaluation of new and other technologies whose effectiveness is poorly known. Epidemiological approaches, methods, techniques, and interpretations are widely used in new and rapidly expanding fields of medicine: research evaluation and synthesis (meta-analysis), establishment of guidelines for clinical preventive practices, new medical technology assessment, guidelines for national and international health policies, evidence-based medicine, outcomes research and disease management ('population-based' medicine and quality of care improvement). In the nearest future, infectious and noninfectious diseases may cease to be almost the sole subjects of epidemiology and they may share their place with other mass phenomena of the next millennium, such as medical practices and care, or political, social and economic actions and their consequences. Not only will primary, secondary, and tertiary Prevention will remain in the epidemiological mainstream, but health protection and health promotion will require perhaps a redefinition of epidemiology in these domains. Epidemiology and preventive medicine are both subjects of medical ethics and dilemma for right choices.

A plane field and a sloped field located at low-land plane and alpine areas, respectively, were monitored with respect to runoff, water quality and fertilizer uses from March to December, 2008. Runoff volume and Non-Point Source (NPS) loads were estimated and analyzed with respect to fertilizer uses. Total TN and TP loads from the sloped field were higher than those from plane field because of larger chemical uses in the alpine field than in the plane field. Organic matter load from plane field was higher than that from sloped field because more organic compost was applied to plane field than to sloped field. Event Mean Concentration (EMC) of measured water quality indices were relatively higher in both fields. Organic matter load per 1 mm rainfall were higher in plane field and TN and TP loads per 1 mm rainfall were higher in sloped field than those in respective comparing field. It was concluded that the type and application method of fertilizer could play an important role in the estimation of NPS pollution loads and the development of Best Management Practices (BMPs). However, it was recommended that long-term monitoring is necessary to better describe the relationship between fertilizer uses and water quality from agricultural fields because numerous natural and management factors other than fertilizer also affect runoff quality.

The purpose of Total Pollution Load Control at Tributary is to obtain maximum improvement effect of water quality through finding the most impaired section of water-body and establishing the proper control measure of pollutant load. This study was implemented to determine the optimal management of reach, period, condition, watershed, and pollution source and propose appropriate reduction practices using the Load duration curve (LDC) and field monitoring data. With the data of measurement, LDC analysis shows that the most impaired condition is reach V (G4~G5), E group (flow exceedance percentile 90~100%) and winter season. For this reason, winter season and low flow condition should be preferentially considered to restore water quality. The result of pollution analysis for the priority reach and period shows that agricultural nonpoint source loads from onion and garlic culture are most polluting. Therefore, it is concluded that agricultural reuse of surface effluent (storm-water runoff with non-point sources) and low impact farming that includes reducing fertilization and controlling the height of drainage outlet are efficient water quality management for this study watershed.

The firms with OHSAS (Occupational Health and Safety Management System) registration should be audited every six months and they have to be reregistered every three years by a third party. In our article audit data were collected from the audit processes of fifty four firms that OHSAS 18001:2007 was implemented and audited by LRQA (Lloyd's Register Quality Assurance). Fifty four firms are largely classified as four categories: civil engineering and construction industry, metal and heavy industry, chemical industry, and other industries including electric, electronic, food, and services. Especially the minor conformity data are analyzed by statistical methods to find out the relationship between four categories of 54 firms and the average number of minor nonconformities. The most frequently appeared minor nonconformities among sub-requirements of OHSAS 18001:2007 are investigated and the reasons for minor nonconformities are specifically explained. The average number of minor nonconformities of firms before and after OHSAS 18001:2007 registration are compared to understand the maturity of OHSAS implementation. Some comments and suggestions are provided for OHSAS to be effectively implemented to the firms if revision is necessary.
