  • Research in which an individual's entrepreneurial spirit contributes to the country's economic development through revitalization of entrepreneurship is being actively conducted, but studies related to individual satisfaction or life satisfaction are still insufficient. This study aims to clarify the influence of young adults' entrepreneurial spirit on their life satisfaction and at the same time verify the mediating effect of self-efficacy and self-determination. In addition, an empirical analysis was conducted on 511 young people to reveal the effectiveness of participation in government start-up support projects. The research results are as follows. First, the entrepreneurial spirit had a positive effect on the life satisfaction of young people. Second, self-determination and self-efficacy played a role in mediating the relationship between entrepreneurship and life satisfaction. Finally, participation in start-up support projects did not show a statistically significant moderating effect. This study is expected to provide a clue that life satisfaction can act as a major variable in the impact of entrepreneurship on entrepreneurship. It also implies that the performance of the government start-up support project should be considered not only about the quantitative performance such as sales and employment effect, but also the qualitative performance such as personal life satisfaction.

  • Korea's port development adjusts the completion time and size of port facilities according to the future port throughput. The current port development system, which is referred to as "throughput-linked port development (Trigger Rule)", has received positive evaluation for efficiently executing the limited port development budget. Recently concerns have been growing over deteriorating service levels in port facilities in Korea due to accelerated aging of terminal facilities. However, the current port development system does not possess any standard for assessing the level of service and utilizing development indicators. The purpose of this paper is to calculate the Port Service Index (PSI) by selecting indicators to measure the Level of Service (LOS) of ports and deriving weights between the indicators, so that the current "throughput-linked port development (Trigger Rule)" can be linked with the level of service. Based on the result of analysis on a variety of preceding studies, the ship waiting rate, berth productivity, ship turnaround time and ship productivity were selected as four indicators to constitute the Port Service Index. The AHP and entropy methodologies were used to derive weights for each of four indicators which were later combined to calculate the comprehensive weight. The calculation formula of the Port Service Index (PSI) was derived by using the aggregated weights of each indicator, based on which the LOS of domestic container and bulk terminals were evaluated and this measurement result was divided into 6 classes to define each LOS. This paper contributes to draw the improvement measures for port development system that are able to connect the quantitative indicator of throughput, as well as a qualitative indicator of the level of "service".

  • Groundwater flow in fractured rock masses is controlled by combined effects of fracture networks, state of geostafic stresses and crossflow between fractures and rock matrix. Furthermore the scaie dependent, anisotropic properties of hydraulic parameters results mainly from irregular paftems of fracture system, which can not be evaluated properly with the methods available at present. The basic assumpfion of discrete fracture network model is that groundwater flows only along discrete fractures and the flow paths in rock mass are determined by geometric paftems of interconnected fractures. The characteristics of fracture distribution in space and fracture hydraulic parameters are represented as the probability density functions by stochastic simulation. The discrete fracture network modelling was aftempted to characterize the groundwater flow in the vicinity of existing large cavems located in Wonjeong-ri, Poseung-myon, Pyeungtaek-kun. The fracture data of $1\textrm{km}^2$ area were analysed. The result indicates that the fracture sets evaluated from an equal area projection can be grouped into 6 sets and the fracture sizes are distributed in longnormal. The conductive fracture density of set 1 shows the highest density of 0.37. The groundwater inflow into a carvem was calculated as 29ton/day with the fracture transmissivity of $10^{-8}\textrm{m}^2/s$. When the fracture transmissivity increases in an order, the inflow amount estimated increases dramatically as much as fold, i.e 651 ton/day. One of the great advantages of this model is a forward modelling which can provide a thinking tool for site characterization and allow to handle the quantitative data as well as qualitative data.

  • The purpose of this study is to provide the proper methods of presenting question materials for generate of various question by comparing type, level, objectivity, manipulation of question in the presenting methods of question phenomena. I selected and showed actual objects, movies, and photographs as ways of presenting question materials, to each of which three question tasks were assigned. The generated questions by students were compared. The results showed that the question of conjectural, predictive, methodological, exploratory, verificational, qualitative, quantitative, simple-manipulative, pre-manipulative questions turned out to have significantly higher average frequencies in the cases of the presentation of photographs and movies than in the cases of the presentation of actual objects. However, the question of post-manipulative questions turned out to have significantly higher average frequencies in the cases of the presentation of actual objects than in the cases of the presentation of photographs and movies. and There were no significant differences between individual methods of question task presentation in average frequencies with respect to causal and methodological, subjective questions. Thus, we have learned from this that methods of presenting question phenomena had influence on the students' question. This suggests that we should consider forms of presentation of question materials in planning the teaching-learning of question.

  • The application of more complex radiotherapy techniques using multileaf collimation (MLC), such as 3D conformal radiation therapy and intensity-modulated radiation therapy (IMRT), has increased the significance of verifying leaf position and motion. Due to thier reliability and empirical robustness, quality assurance (QA) of MLC. However easy use and the ability to provide digital data of electronic portal imaging devices (EPIDs) have attracted attention to portal films as an alternatives to films for routine qualify assurance, despite concerns about their clinical feasibility, efficacy, and the cost to benefit ratio. In this study, we developed method for daily QA of MLC using electronic portal images (EPIs). EPID availability for routine QA was verified by comparing of the portal films, which were simultaneously obtained when radiation was delivered and known prescription input to MLC controller. Specially designed two-test patterns of dynamic MLC were applied for image acquisition. Quantitative off-line analysis using an edge detection algorithm enhanced the verification procedure as well as on-line qualitative visual assessment. In conclusion, the availability of EPI was enough for daily QA of MLC leaf position with the accuracy of portal films.

  • Since 1980, the number of universities have increased dramatically. However, compared to the quantitative growth, the lack of qualitative growth has often been criticized. Students entering university are estimated to decrease by half in 2025 compared to 2014. In swift response to challenges with decreasing student enrollment, the first University Reform Evaluation (URE) for innovating universities, was conducted and resulted in controversy. Opposition is based on distrust of the overall system, questioning the reliability of the evaluation process utilized for the URE evaluation index. Meta-evaluation is required to improve the quality of evaluation, and standards developed prior to conducting the URE. Therefore, an interdisciplinary approach is necessary for the evaluation of human resource development. This research uses the interdisciplinary approach from the human resources development point of view in attempting to develop meta-evaluation criteria which will enable effective evaluation and analysis of URE. The meta-evaluation standard features the creation of the ERPOU model, by conducting literature review, and considers data from expert symposiums, and surveys. The ERPOU model consists of 5 evaluation fields, 21 evaluation categories, and 42 evaluation standards.

  • Fish community in the Hoengseong Reservoir was investigated from April to October 2005. The total number of fish caught from the period was 8,626 fish representing 22 species and 8 families, using tyke net and trammel net. Besides biomass was 122.9 kg. In the fyke net, 8,168 individuals caught during the period represented 21 species belonged to 8 families, its biomass was 90.6 kg. On the other hand, 458 individuals caught in the trammel net during the period represented 16species belonged to 6 families, its biomass was 26.3 kg. The results showed that the trammel net had lower number of species, individuals, and less biomass compared to those of the tyke net. Number of species confirmed was increased according as mesh size of the net was smaller. Besides, the fyke net with small mesh size was able to collect not only small-sized fish but also large-sized fish so that it was suitable to study qualitative and quantitative analysis of fish fauna in detail. Whereas, the trammel net with proper mesh size was effective to determine composition of fish species in the studied area.

  • In order to uncover the subsurface geological structure in the southwestern rim of the Ogcheon Fold Belt including the Cretaceous Neungju Sedimentary Basin, we analysed and interpreted the aeromagnetic anomalies over the region. The study area belongs to Muan-gun, Yeongam-gun, Gangjin-gun, Jangheung-gun, and eastem Haenam-gun. From the qualitative analysis and quantitative modeling of the reduced-to-the-pole magnetic anomalies, following things are revealed or suggested; Even though the porphyry of higher susceptibility is not crop out in the Donggang Myeon in the northwestern part of the study area, it is supposed to have intruded the Precambrian gneiss and the Cretaceous Bulgugsa granite of lower susceptibility. Two-dimemsional modeling of profile data across the sedimentary basin of Neungiu Group reveals that the northern part of the basin is deeper than the southern part, and that the maximum depth of the basin is supposed to be $3\cal{km}$ below the surface. The western flank of the basin bottom is steeper than the eastern flank. The high susceptibility value of the Neungju Group sedimentary rocks indicates that the rocks comprises large amount of volcanic materials. This fact implies that it is hard to expect hydrocarbon reservoir in the sedimentary rocks of the Neungiu Basin.

  • The recent trend for pesticide residue analysis in food involves fast cleanup and use of mass spectrometry to achieve quantitative and qualitative analysis at the same time. Recently, the QuEChERS (quick, easy, cheap, effective, rugged and safe) multi-reside method has received much attention as a fast extraction and cleanup method of pesticide residue analysis. Therefore, multi-residue analysis of 236 pesticides was tested with the QuEChERS method by concurrent use of PTV-GC/TOFMS (gas chromatography/ time-of-flight mass spectrometry with programmable temperature vaporizer). PTV condition was optimized and when the method was applied to apples, pesticide recovery rates (spiked at 400 ng/g) ranged from 80% to 120%, and RSD values were under 10% for most compounds. The results showed that the QuEChERS sample preparation and PTV-GC/TOFMS analysis can be applied to multi-residue analysis of pesticides in fruits and vegetables.
