This study attempted to characterize conflict frames of environmental disputes by examining twelve actual wetland permitting cases in Ohio. The participants consisted of such interested parties as applicants, technical, legal or environmental consultants to applicants, U.S.Army Corps of Engineers, U.S.Environmental Protection Agency, U.S.Fish and Wildlife Service, Ohio Environmental Protection Agency, Ohio Department of Natural Resoures, local agencies, the environmental community, and citizens who have been involved of the permitting process. The purpose of this study is to provide empirical evidence of how different perceptual frames existed in the wetland conversion disputes, and to understand different environmental conflict frames that influenced disputants' perception relating to dispute resolution. The vehicles used to collect the necessary data were three survey instruments : Open-ended questionnaires, Likert-type questionnaires, and ranking questionnaires. Forty-three subjects were contacted for open fact-to-fact interviews, 53 subject for Kikert-type mail survey and 54 subjects for ranking instrument mail survey. Analyses of survey results revealed that six different types of frames were clearly identified from all the parties involved in Ohio wetland conversion disputes. It revealed that disputants had statistically significantly different levels of perception to the frames based on the participants' role (i.e. regulator, applicant, commentor), the number of involved parties in the process, processing time and the issuance of a permit. The findings also revealed that information sharing among disputants played a significant role in the process of froming and reframing. The alternative idea, building cooperation through negotiation, was proposed to provide new insight into the resolution of the dispute.

This study concerns with an applicability of the management science approach to the score adjustment among the College Scholastic Aptitude Test(CSAT) optional subjects. A linear programming model is developed to minimize the sum of score distortions between optional subjects. Based on the analysis of the 377,089 CSAT(2010) applicants' performances in social science test section, this study proposes a new approach for the score equating or linking method of the educational measurement theory. This study makes up for the weak points in the previous linear programming model. First, the model utilize the standard score which we can get. Second, the model includes a goal programming concept which minimizes the gap between the adjusting goal and the result of the adjustment. Third, the objective function of the linear programing is the weighted sum of the score distortion and the number of applicants. Fourth, the model is applied to the score adjustment problem for the whole 11 optional subjects of the social science test section. The suggested linear programming model is a generalization of the multi-tests linking problem. So, the approach is consistent with the measurement theory for the two tests and can be applied to the optional three or more tests which do not have a common anchor test or a common anchor group. The college admission decision with CSAT score can be improved by using the suggested linear programming model.

1990년 이후 국내 저 출산 붐으로 인한 대학 입시생들의 감소로 인하여 2016년 이후는 대학 정원이 수험생들의 수요보다 많은 상황으로 예측된다. 이로 인해 지방대학들의 학생 충원이 대학의 존폐여부를 좌우할 만큼 학생수급 정도가 심각한 상황으로 부각되고 있다. 따라서 전국 대부분 대학들은 우수한 인재들을 선점하기 위한 특성화 및 전문화된 방식으로 신입생들을 선발하는 다양한 전형방법을 개발하여 시행하고 있다. 본 연구는 지방의 A국립대학교를 중심으로 동일계 특별전형 입학생들에 대한 통계적 분석을 통해 이들을 효과적으로 관리할 수 있는 방법을 찾아보고자 한다. 동일계 특별전형 입학생들을 대상으로 통계적 방법을 통한 재학현황과 학내 적응여부를 분석하고 계열별 성별과의 관계를 파악하여 보다 나은 신입생 선발을 위한 방법에 대해 살펴본다. 저 출산으로 인한 학생 수의 감소로 정원 외로 전형하는 동일계 특별전형을 통해 인재를 확보하는 방안으로 활용할 수 있으며, 이를 토대로 졸업 시까지 학생들을 추수 관리할 수 있다. 또한 다른 전형으로 확대하여 분석을 하고 서로 비교한다면 앞으로의 입시정책에 적합한 전형유형을 개발할 수도 있을 것이다.

Along with the low birth rate in Korea, the aging of mothers is progressing very rapidly. Recent studies have reported that the obstetric infrastructure is crumbling due to the accelerating closures of obstetric medical institutions resulting from the low birth rate and low reimbursement rates for obstetric procedures. The number of birth centers has also decreased, but women's interest in natural birth has actually increased, such that deliveries at birth centers now account for 11.8% of deliveries in obstetric clinics. In the Netherlands, Japan, and the United Kingdom, initiatives to promote natural birth through care provided by midwives increased the rate of natural births, decreased the number of cesarean sections, and lowered the rate of postpartum complications. In light of these examples, South Korea should also encourage natural delivery by midwives. A national support system for midwife applicants is necessary, and the requirements for institutions that train midwives should be revised. Independent birth centers should have emergency prescription privileges, and women should be given the choice to have a natural delivery by creating birth centers within hospitals.

This paper proposed a quantitative evaluation method to measure the operational effectiveness of the local military manpower administrations. The proposed method compared the relative operational effectiveness level for 12 local military manpower administrations in Korea.. The method used the IDEA (imprecise Data Envelopment Analysis) model which Is able to measure relative operational effectiveness level, and also used two input variables (labor cost, operational cost) and three output variables (number of military applicants, number of civil application approved & processed, management accuracy level). Through the model output analysis, we presented the relative effectiveness scores, the reason for non-effectiveness, and the relationship between non-effective ness level and input/output variables for each local military manpower administration. We also presented a few recommendations how to improve the effectiveness level on particular local military manpower administration.

Design patent is a type of industrial design right that is granted on the ornamental design of a functional item. We analyzed domestic design patents that were applied from 1965 until 2008, to the field of functional clothing. Since the year 2000 the number of design patents of functional clothing progressively increased. Design patents applied to the functional clothing field includes sport wear (47%), working clothes (34%), and leisure wear (19%). Design development of the sports wear from the latter half of 1990's has shown a continuously increasing tendency. The most patent applications belonged to the companies(51.4%), followed by individual applicants (46.6%), and the universities or laboratories had the least number of applications (2.0%). In case of working clothes or the leisure wear, the number of design applications focusing on the functional characteristic is higher than that of aesthetic characteristic, however, the number of design applications focusing on the aesthetic characteristic is higher in sportswear.

Indoor gardens tailored to suit individual tastes offer a place to enjoy plants and to relax to city dwellers to relieve stress from city life. However, there are technical issues to build such indoor gardens. To offer solutions to technical issues, this study aims to analyze development phases of indoor garden-related technologies by studying available patents in detail. Also, the study aims to understand current status and future direction of technologies by examining technological trends for introduction of indoor gardens. Brainstorming method was used to understand technology trends and as a result, two groups were identified for technical features of indoor gardens: indoor greening technology and rest area for users. An analysis on selected patents showed that the number of patents increased until 2010 and declined gradually afterwards. Korea ranked the highest in the number of patents grant followed by USA, Japan and Europe. Similar order was observed with the number of patents granted by nationality of applicants. The number of patents granted by nationality was the highest for Korean nationals. For indoor greening technologies, patents related to structure from 2007 were mostly concentrated in the areas of irrigation control and environment control for plants and vegetation. For rest area related technologies, patent related to structure showed a repetitive pattern of increasing and decreasing, but overall, on downtrend. For further development and dissemination of indoor gardening technology, more R&D work is needed with focus on environmental control technology for designing suitable environment for both human and plant.

The Korean Long-Term Care Insurance (K-LTCI) provides financial support for long-term care service to people who need various types of assistance with daily activities. As the number of elderly people in Korea is expected to increase in the future, the demand for long-term care insurance would also increase over time. Projection of future expenditure on K-LTCI depends on the number of beneficiaries within the grading system of K-LTCI based on the test scores of applicants. This study investigated the suitability of mixture distributions to the model K-LTCI score distribution using recent empirical data on K-LTCI, provided by the National Health Insurance Service (NHIS). Based on the developed mixture models, the number of beneficiaries in each grade and its variability under the current grading system were estimated by simulation. It was observed that a mixture model is suitable for K-LTCI score distribution and may prove useful in devising a funding plan for K-LTCI benefit payment and investigating the effects of any possible revision in the K-LTCI grading system.

In order to study the effect of K-WAIS and FTD on flight aptitude, which we utilize to sort out good pilot candidates among applicants, we adopted Fuzzy regression model and expressed the result of flight aptitude tests in Fuzzy number by using maximum/minimum values and mean values. The 7 aspects of K-WAIS were broken down into three similar groups: mathematical ability, visualization ability and organization ability. While mathematical ability and organization ability showed a positive relevance with the FTD test with respect to flight aptitude, visualization ability of K-WAIS showed a negative(-) relevance with flight aptitude, which presented an opposite result to the previous research. Thus, we are to increase the number of samples and do the research thereof in the near future.
