In this paper We analyze the correlation between investment and performance of Korean R&D programs, by six factors diversified, based on evolutionary economics of technology. National Science and Technology Information Service(NTIS) started from March, 2008 was used for collecting investment and performance data of national R&D program. We search the investment cost according to science-technology standard classification of Korea, research conductors, socio-economic objectives and cooperation types per year from 2002 to 2008, and we regard this data as "investment". Similarly, we search the number of papers, patents, commercializations, royalties and so forth according to science technology standard classification of Korea, research organizations, socio-economic objectives and cooperation types per year from 2002 to 2008, and this data is regarded as "performance". We expected analysis results of this investment and performance data confirm the diversified factors to affect advancement of science and technology. And we though, as a result, we will get some meaningful directions of investment of national R&D from the analysis results. But this study has several limitations because we did not consider enough microscopic characteristics of sector or technology, research organizations, cooperation network types, and external effect of social, politic, cultural factors.

Problems concerning the vital registration system and its management, errors and methods to adjust them in the vital registration data in Korea have been studied. It is found that birth and death registration rates were above 95% in 1994. The registration rates rose rapidly since 1970 due to 1) simplification of registration form, 2) improving accessibility by allowing registration at the current residence, 3) enforcing fine against non-registration, and 4) improvements in social security system. However, there should be some continuing efforts for further improvement of the vital registration system. The content error in the data could be substantially reduced following the rapid rise of the registration rates in the 1980s, though this has never been actually studied. There are still substantial registrations with false date of death. The false date of events may affect the computed vital rates specially when the registration rates are rapidly rising. Especially the death rates of the young can be seriously affected. A study on the data in the 1970s shows that death of age between 3 to 19 has been over-registered up to 67% compared with the expected. It is a serious matter that some researchers analyze the registration data without adjusting the errors. It is strongly recommended for the Government Statistical Office to undertake a study on the registration behavior of the people.

This study was conducted to identify the BMI of enlisted soldiers, to understand the difference between their BMI and that of other men in their age group, and to identify the influence factors of enlisted soldiers' BMI change. The survey has been conducted self-evaluation questionnaire from 23 Feb. 2009 to 31 Mar. 2009 from 4 different forces as methods. Independent-sample T-test, chi-square test and multiple linear regression analysis were used for statistical analysis from 301 collected data. As a result of surveying enlisted soldiers' BMI, their obesity rate 18.6% was lower than 22.1% of other men in their age group. In terms of health behavior, the underweight&normal weight group(2.39) showed higher diet score than the overweight group(2.13), showing that the underweight&normal weight group ate relatively slowly, less spicy and less sweet food compared to the overweight group. The overweight group(2.25) showed lower satisfaction with their body type than the underweight&normal weight group(2.98), while the overweight group(4.01) showed a significantly higher score than the underweight&normal weight group(3.37) for weight control activity. The influence factors of BMI change were diet habit, subjective perception of body type, and weight control activity. In order to improve of enlisted soldiers' BMI, it would be necessary to improve the food service and the snack bars for interventional control of food that influence obesity, rather than personal effort, in addition, education for right body-shape perception and encouraging on weight control activity.

The objective of this research is to investigate how implementation of smart factory systems(SFS) effects management accounting(MA). The results based on data collected from 108 Korea small and medium enterprises(SME) confirmed that SFS implementation caused significant MA changes. Estimated regression models revealed that the most important SFS characteristic were the analytical capabilities since it positively influenced MA changes in four dimensions: internal reporting, budgeting, application of modern accounting techniques and MA employee's job. In the segment of budgeting, the quality of implementation of specialized bedgeting software had significant and positive influence. The only negative correlation founded was the one between the uncertainty of business environment and adoption of modern accounting techniques. Results from this study provide that SME should put special focus on implementation of business analytics modules in order to achieve comprehensive benefits in MA prctices.

최근의 통신서비스 시장은 경쟁의 도입과 기술의 발전이라는 두 축에 힘입어 양질의 서비스를 보다 저렴한 요금으로 소비자들에게 제공하고자 노력하여 왔다. 그러나 이러한 통신서비스의 질적 향상 노력에도 불구하고 여전히 통신서비스의 품질은 소비자들의 기대수준에는 미치지 못하고 있다는 지적이 있다 더욱이 문제가 되는 것은 소비자가 인지하고 있는 통신 서비스 품질의 기대수준은 시간의 흐름에 따라 동태적으로 변화하는 것이어서 한 시점에서의 통신 서비스 품질 수준의 측정으로는 정책적으로 큰 의미를 설명하기 어려운 실정이다. 이와 관련하여 많은 선행 연구들이 다양한 측면에서 시행되어져 왔지만 이제까지의 많은 선행 연구들은 대부분이 통신서비스의 특성을 제대로 고려하지 않고, 고객만족의 향상과 불일치를 가져오고 있는 성능품질만을 측정한다거나, 시간의 흐름에 따라 변화해 가는 소비자가 서비스에 대해 인지하고 있는 중요도나 기대수준을 고려하지 않고 있으며, 각 구성요소간의 동태적 인과고리에 대한 고려 없이 연구가 이루어져 전반적인 통신 서비스의 고객만족을 전체적인 시각에서 평가한 연구는 극히 드물다. 따라서 본 연구는 통신서비스의 고객만족을 피드백 관점, 동태적 관점, 사실적 관점의 시스템 다이내믹스 방법론을 적용하여 전반적인 동태적 고객만족 모형을 구현하고 이를 정책적으로 활용할 수 있는가에 대한 접근을 시도하였다. 고객만족은 결코 한순간에 머물러 있는 것이 아니며 체감품질 및 기대수준의 영향을 받아 지속적으로 변화해간다 따라서 어떻게 기대수준을 관리하고 고객의 기대에 부응하는 체감품질을 관리하는 것이 지속적인 고객만족을 획득할 수 있는 가를 시뮬레이션 모형을 통해 가시적으로 시스템의 행태를 구현함으로써 그 이해의 폭을 넓히고자 시도하였다.으로써 웹에서의 혁신적이며 크로스 사이트, 크로스 장르적인 컨텐츠 플래닝의 가능성을 시사하는데 의의가 있다고 하겠다.y used to some of interactive storytelling through hyper text in CD-ROM and web sites.

In Korean construction industry, a public sector's ordering volume has been constantly increased after 2000. But, because a cost, schedule and quality control generally depends on a result-centric management form and a transparent management is not done during the construction in the Korean public business, it is recognized that this causes problems including an increase of cost and schedule, incomplete construction, a difficulty to find the problem in advance to establish measures, and an unclear locus of responsibility of constructor, supervisor and designer. Accordingly, this study is intended to derive the problems and the limit of management by identifying and analyzing the management state of the present government construction client for the client organization of public sector's government construction. Also, the study is intended to contribute to the client's efficient and actual project management by presenting the model of supplementing or improving the derived problem and limits to the client's organization.

Offering subject-oriented services by subject experts is an effective method of enhancing the quality of digital reference services in university libraries. However, it is not easy to implement due to the Korean librarian education system and a shortage of human resources. Thus, as an alternative, we proposed an SDI (selective dissemination of information) profiler system using the concept of a profiler which is used in crime psychology as a specialist who studies a person's behavior for clues to psychology to aid in capturing them, under the assumption that conducting SDI services is one of the subject experts' key roles. And we also mentioned the procedures and methods of how to apply it to the reference services of university libraries. The proposed SDI profiler system can change the roles of university librarians from passive to active. Furthermore, it also allows librarians to provide their clients with customized SDI services, thus improving reference services.

Objectives: This study investigated the relationship between the Korean healthy eating index (KHEI) and periodontal disease in the Korean adult population. Methods: The data used in the analyses were obtained from the seventh Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed by chi-square tests and t-test. Multiple regression analysis was also performed to assess the association between KHEI and periodontal disease. Statistical significance was set at p<0.05. Results: Multiple logistic regression analysis adjusted for socioeconomic variables showed that medical and health behavior variables were significantly related to the KHEI 1 (<63.7, odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.03-1.46), KHEI 2 (63.7-79.9, OR: 1.14, 95% CI: 0.97-1.34), and risk for periodontal disease. Conclusions: The results showed a significant association between the KHEI and periodontal disease in the Korean adult population.
