Research performance evaluation in Korean universities follows strict guidelines that specify scoring systems for publication venue categories and formulas for co-authorship credit allocation. To find out how the standards differ across universities and how they differ from bibliometric research evaluation measures, this study analyzed 25 standards from major Korean universities and rankings produced by applying standards and bibliometric measures such as publication and citation counts, normalized impact score, and h-index to the publication data of 195 tenure-track professors of library and information science departments in 35 Korean universities. The study also introduced a novel impact score normalization method to refine the methodology from prior studies. The results showed the university standards to be mostly similar to one another but quite different from citation-driven measures, which suggests the standards are not quite successful in quantifying the quality of research as originally intended.

근로장려세제는 저소득가구의 근로를 장려하고 실질소득을 지원하는 근로 연계형 소득지원제도이다. 따라서 노동시장의 밖에 있는 저소득가구를 얼마나 노동시장으로 유인했는지가 근로장려세제의 평가에 있어서 가장 핵심적인 질문이라고 할 수 있다. 본 논문은 2008년 시행 이후 여러 차례 세법개정에 따라 근로장려세제의 수급자격요건과 급여체계가 바뀌어 왔다는 점을 이용하여 근로장려세제의 노동공급 효과를 추정하고자 한다. 한국복지패널, 가계금융복지조사, 한국노동패널, 재정패널 자료를 이용하여 분석한 결과, 통계적으로 유의하면서 긍정적인 효과와 통계적으로 유의하지 않은 효과가 혼재되어 나타났다. 한편 2013년까지로 분석기간을 한정했을 때 긍정적 효과가 좀 더 크게 나타났는데, 사업소득자와 기초생활수급자의 수급자격을 인정한 이후에 효과성이 낮아진 것인가에 대해서는 후속연구가 필요하다.

The advantage of internet survey compared to the traditional survey methods are speedy in data collection, cost-effective, high performed design and able to data process and analysis at the same time. The other side are difficult to select sample, come from serious nonresponse errors. We suggest the new internet survey method to the questionnaire design that have the high response rate, enough to advanced preparations and system stability.

Based on customer information and financing processes in capital market, we derived individual models by applying multi-layered perceptrons, MDA, and decision tree. Further, the results from the existing single models were compared with the results from the integrated model that was developed using genetic algorithm. This study contributes not only to verifying the existing individual models and but also to overcoming the limitations of the existing approaches. We have depended upon the approaches that compare individual models and search for the best-fit model. However, this study presents a methodology to build an integrated data mining model using genetic algorithm.

혼합분포를 가정한 신용평가 연구에서 ROC 곡선은 부도와 정상 차주의 판별력을 탐색하는데 유용한 그림이다. ROC 곡선을 개선하여 스코어를 파악할 수 있는 AROC 곡선을 수리적으로 분석하고, 정규분포를 적용하여 다양한 곡선의 형태를 파악한다. 최적분류점을 발견하는 다양한 분류정확도 통계량과 AROC 곡선의 관계를 발견하고, 두 분포의 분산이 동일한 경우에 AROC 곡선의 극소점으로 최적의 분류점을 추정할 수 있음을 발견한다.

This paper proposes a new effective installed reserve rate in order to evaluate reliability of power system considering renewable generators, which include uncertainty of resource supply. It is called EIRR(effective installed reserve rate) in this paper. It is developed with considering capacity credit based on ELCC by using LOLE reliability criterion. While the conventional installed reserve rate index yields over-evaluation reliability of renewable generators, the proposed EIRR describes actual effective installed reserve rate. However, it is not the probabilistic reliability index as like as LOLE or EENS but another deterministic effective reliability index. The proposed EIRR is able to evaluate the realistic contribution to the reliability level for power system considering wind turbine generators and solar cell generators with high uncertainty in resource supply. The case study in model system as like as Jeju power system size presents a possibility that the proposed EIRR can be used practically as a new deterministic reliability index for generation expansion planning or operational planning in future.

The purpose of this study were to develop a financial management educational program for college students and to evaluate the effect of this program. In order to achieve this aims, a fundamental work to select the educational contents was preceded with a survey of learners' needs, preceding studies. After choice of educational contents, learners' demands on how to manage the educational program was executed in advance. The participants in this study were 500 students, resulting in 460 with usable data. Second, reflection the above mentioned educational contents, a concrete financial management educational program was built. This program consists of 9 domains: financial planning, careers and income, consumer spending, credit use and Credit cards, Managing Taxes, investment planning, risk management and insurance, retirement and estate planning, contribution. The participants for this program implementation were 68 students. Third, to evaluate the effects of the financial management educational program, paired t-test was conducted in using the SPSS package. The result suggested that financial management educational program has a positive effect on financial knowledge, financial attitude and financial management behavior. Several implications based on the findings were suggested.

Purpose: The purposes of this article were to analyze curricula of gerontological nurse practitioner(GNP) programs in the United States, to compare the curricula with Korean GNP programs, and to provide suggestions for better GNP programs in Korea. Methods: Top GNP programs in the United States were identified from the US NEWS and 12 universities were included in the analyses. Class distribution, credit hours, and clinical hours were analyzed and suggestions for Korean GNP programs were made. Results: Average credit hours for class lectures in the US GNP programs were 47 and emphases on physiology, pharmacology, physical assessment, and disease management were identified. Most US GNP programs(75%) provided health concerns for both middle aged and older adults. Not all US GNP programs included 'theory' or 'the introduction to GNP' classes, while these are required classes in the Korean GNP program. The mean clinical hours in the US GNP Programs were 537 which are much higher than those in the Korean GNP program. Conclusion: Based on the analyses, we can conclude that Korean GNP programs are lacking in many ways. Further evaluation and curricula modifications are required to settle down the program better and to have the graduates prepared more as internationally competent nurse practitioners.

This study examines whether Korean rating agencies such as Korea Investors Service (KIS), National Information & Credit Evaluation (NICE), and Korea Ratings Corporation (KR), incorporate corporate governance into their corporate bond ratings in Korea. We find that the Korean rating agencies assign higher ratings to the bonds issued by Chaebol (Korean business group) affiliated firms. Our results also indicate that those rating agencies give higher ratings to the bonds with greater foreign investor share ownership. Moreover, if the rating agencies value corporate governance, higher rated firms should issue bonds at lower yield to maturity. We discover that Chaebol affiliation is counted favorably by the rating agencies. We find that investors are willing to pay lower risk premium for bonds with higher institutional ownership, but higher risk premium to bonds with greater equity ownership in the form of depository receipts. Therefore, even if the rating agencies and investors in Korea consider corporate governance (Chaebol affiliation and ownership structure) an important determinant in bond ratings and the yields to maturity, they have opposite views on institutional ownership and share ownership in the form of depository receipts.
