It is anticipated that Gadeok New Airport will be constructed, and the entity responsible for its operation will be a new airport authority, not the existing airport corporation, as the Ministry of Land, Infrastructure and Transport has announced its plan to establish the Gadeok New Airport Construction Authority. Based on the precedents of existing airport corporations, it is expected that the future authority will undergo organizational changes to become an airport corporation. This study seeks to establish criteria for selecting overseas airports for benchmarking when researching the entity that will operate the newly established Gadeok New Airport authority. To provide a specific basis for selecting overseas airports for the future operation of Gadeok Airport, the Delphi survey method will be used to derive criteria. Currently, when examining the participation of local governments in regional airports, Gimhae International Airport is operated solely by the Korea Airports Corporation, receiving criticism for the lack of participation by the local government, such as Busan City, in decision-making related to airport operation and local reinvestment. Therefore, it is deemed necessary to provide early direction for improvement in this regard.

The tribe Neillieae, a small group of about 18 species in the Rosaceae, comprises three taxonomically difficult genera, Neillia, Physocarpus, and Stephanandra. The tribe, characterized by lobed leaves with persistent or deciduous stipules and ovoid, shiny seeds with copious endosperm, is strongly supported as a monophyletic group by a variety of lines of molecular evidence. Due to the high amount of morphological variation across the three genera and the species in tribe Neillieae, conflicting classification schemes and numerous species have been proposed over the past three centuries. However, no comprehensive systematic study of the group, including all species across their geographic ranges, has ever been undertaken. As part of a taxonomic revision of tribe Neillieae, a revision of Physocarpus based on the morphological examination of herbarium specimens, including types, and field observation is presented. Artificial keys, comprehensive nomenclatural treatments, descriptions, distribution maps, and lists of specimens examined are provided. Six species in Physocarpus are recognized. A lectotype is here designated for the following species: Opulaster pubescens, Opulaster ramaleyi, Spiraea opulifolia var. parvifolia, Spiraea opulifolia var. tomentella, Physocarpus michiganensis, and Physocarpus missouriensis.

Providing the income support program for people under the poverty level has been regarded as the basic obligational role of modern government. The target population of this program should include all the poor who are unable to maintain the minimum health and decency level with their own income. The minimum living cost, however, varies within a country because there are regional differences in consumer price and the mode of living. The current program does not count for the regional differences, leaving a significant portion of Seoul's poor needy people being ineligible for this public care. Recognizing these regional differences, this paper attempts to estimate the minimum living cost in Seoul area, comparing it to the national one. It employs the data and method that the Korea Institute of Health and Social Affairs adopted in its 1994 study, since it has been served as a basis of the current public assistance program. The minimum cost of living in Seoul is estimated to be \887,611 per month for a 4-person household. It is 1.33 times greater than the national monthly minimum of \666,684. Based upon the '94 urban household expenditure survey data, some 5.9 percent of Seoul's population, 636,132 people, are found to be under the Seoul's minimum living level. This number is 5.2 times greater than those 123,304 people who are eligible for the current public assistance program in Seoul.

This study was conducted to investigate characteristics related to lacquer yield and to evaluate possibility of indirect selection of Rhus verniciflua Stokes. Twenty-four lacquer trees were randomly selected for measuring growth, urushiol content and bark thickness. Urushiol content showed a significant positive correlation with outer bark thickness and secretory canal density at 1% level, and with inner bark thickness at 5% level. Bark thickness and secretory canal density could be used as indicators for high urushiol content within bark and thus for high lacquer yield. Mass selection for high lacquer yield was made based on urushiol content within bark. Sixteen individuals with the highest urushiol content value were selected for breeding. As expected, the selected trees had thicker bark, higher density of secretory canal, better developed secretory canals compare to the non-selected lacquer trees.

In this study, basic data is consisted annual maximum rainfall at 56 stations that has the rainfall records more than 30years in Korea. The 14 probability distributions which has been widely used in hydrologic frequency analysis are applied to the basic data. The method of moments, method of maximum likelihood and probability weighted moments method are used to estimate the parameters. And 4-tests (chi-square test, Kolmogorov-Smirnov test, Cramer von Mises test, probability plot correlation coefficient (PPCC) test) are used to determine the goodness of fit of probability distributions. This study emphasizes the necessity for considering the variability of the estimate of T-year event in hydrologic frequency analysis and proposes a framework for evaluating probability distribution models. The variability (or estimation error) of T-year event is used as a criterion for model evaluation as well as three goodness of fit criteria (SLSC, MLL, and AIC) in the framework. The Jackknife method plays a important role in estimating the variability. For the annual maxima of rainfall at 56 stations, the Gumble distribution is regarded as the best one among probability distribution models with two or three parameters.

As game players have been more diverse and new features of digital games have been emerged in recent days, it is important to find out and understand how recent game players recognize and classify digital games. Thirty game players conducted Q-analysis of twenty-nine Q-statements extracted from previous studies on game typology. By using a QUANL program, three different types were revealed. For game classification, 'Physical Environment Centric Players' type highly values external game elements from the outside perspectives. 'Contents Centric Players' type considers internal game elements as the most important criterion. 'Emotional Experience Centric Players' type values his/her subjective feeling and thoughts. Based on this study, it is expected to make a contribution in developing a framework of game players with their perspectives on game classification.

The purpose of this study was to find differences in evaluation criteria and to find differences in preferred images based on benefits segmented groups of jeans products consumers. Male and female Korean university students participated in the study. Quota sampling method was used to collect the data based on gender and a residential area of the respondents. Data from 492 questionnaires were used in the analysis. Factor analysis, Cronbach's alpha coefficient, cluster analysis, one-way ANOVA, and post-hoc test were conducted. As a result, respondents who seek multi-benefits considered aesthetic criteria(e.g., color, style, design, fit) and quality performance criteria(e.g., durability, ease of care, contractibility, flexibility) more importantly when evaluating and purchasing jeans products. Respondents who seek brand name considered extrinsic criteria(e.g., brand reputation, status symbol, country of origin, fashionability) more importantly than respondents who seek economic efciency. Respondents who seek multi-benefits such as attractiveness, fashion, individuality, and utility tend to prefer all the images: individual image, active image, sexual image, sophisticated image, and simple image when wearing jeans products. Respondents who seek fashion are likely to prefer individual image, and respondents who seek brand name more prefer both individual image and polished image. Mean while, respondents who seek economical efficiency less prefer sexual image and polished image.

This study, according to the amendment of the Act on External Audit, on the basis of the number of input auditors, the content of auditing, and audit times as additional informations, calculates the average of the samples listed companies with assets of one hundred billion KRW. However, since the actual number of the subject corporations of which asset is 100 billion KRW is small, it is difficult to extract data with reference to this asset size. Therefore, the samples were extended to 50 corporations of which asset is 10% less than 100 billion KRW and other 50 more corporations of which asset is 10% more than 100 billion KRW. As a result, a total of 100 corporations were included as samples. To calculate the average of the audit times, a t-test was performed between the two groups. The result of the t-test showed that there is not a significant difference between the two groups. According to the analytical results of the t-test, the average of the number of input auditors and the average of audit times were calculated with respect to all the 100 samples. A further analysis showed that the average of audit content in the present study was compared with the estimated values in the study of Mun (2016). Although the results of this study may not be the optimal number, they may be used as a fundamental index which may be compared with the audit times and the audit fees in the current audit market where there is not an available reference. In addition, the amendment of the Act on External Audit may enhance the independence of auditors and the transparency of accounting system when compared with the previous system where only the total audit times were disclosed.

The objective of the study is to evaluate the effect of variabilities (uncertainties) in materials and testing on contractor payment and to suggest a base for adjusting the unsuitable specification. Most commonly used acceptance plans were used to estimate payment using simulation. Simulation results that were graphically illustrated by means of operating characteristics (OC) curves in terms of expected payment showed that contractor received a reduced payment due to intrinsic sampling and test variabilies. The most significant reduction was caused due to relatively large magnitude of the testing variability. Therefore, the tolerance range in acceptance plan should be revised as compared with typical testing variability.

본 연구는 영국의병원 급식체계를 분석하고 그에 대한 객관적, 주관적 평가를 시도하는데 목표를 두고 있다. 영국 보건성의 지원하에 12개 병원에 대한 급식체계를 비용편익 분석과 생산성 측정이라는 객관적 기법, 그리고 Indepth-interview 및 Self-Administered Qestionnaire 라는 주관적 방법을 통해 분석하였다. 이 중 본논문에서 다루는 것은 환자 만족도와 이에 영향을 미치는 병원 급식 체계의 결정요인 부분이다. 제1단계 연구에서는 급식대상 환자들에 대한 표본추출을 통해 설문조사를 실시하였다. 분석결과 환자의 인구통계학적, 정서적 변수가 환자의 만족도에 가장 큰 영향을 미치는 요소로 나타났다. 각병원에 대한 객관적 자료를 이용한 2차 희귀분석 결과 인적자원요소와 시스템요소로 대별된 독립변수 요인군종 어느 변수도 0.05(p) 수준에서 유의미하지 않은 것으로 밝혀졌다. 환자의 만족도는 병원 급식체계에 기준한 객관적인 결정요인에 의해 설명되어지지 않고 오히려 환자 자신의 변수에 의해 결정되어짐을 알수 있다. 본논문이 시사하는 바는 급식체계에 대한 평가에 있어 이론적 모형과 변수의 선정이 수정될 필요가 있다는 점과 방법론적 차원에서 평가대상 급식시스템의 유형상 특성이 고려되어야한다는 점이다.
