The subjective question is appropriate for evaluation of deep thinking, but it is not easy to score. Since, regardless of same scoring criterion, the graders are able to produce different scores, we need the objective automatic evaluation system. However, the system has the problem of Korean analysis and comparison. This paper suggests the Korean syntactic analysis and subjective grading system using the syntactic-semantic tree comparator. This system is the hybrid grading system of word based and syntactic-semantic tree based grading. This system grades the answers on the subjective question using the syntactic-semantic comparator. This proposed system has the good result. This system will be utilized in Korean syntactic-semantic analysis, subjective question grading, and document classification.

The form of travel has been changing to dynamic, experience and family. Festivals are popular, specially the historic culture festivals, whose themes are a history event, a time and the people, are preferred to families because they give visitors opportunities of education and experience. Evaluation of festivals is important that it diagnoses the problems and enhancement One of the evaluation methods, Importance-Performance Analysis is useful which it is easy to find priority with visual matrix without complex statistical technique and a technical terminology. This research used IPA to evaluate The Yeoncheon Jeongok Paleolithic Festival which is one of the popular historic culture festivals. From the result 'unique food', 'rest facility', 'other convenience facility', 'hygiene', 'crowding' were included in selected to 'concentrate' territory of the IPA matrix. Therefor the festival manager should put his efforts to develop unique food, build more rest and other convenience facilities, enhance hygiene, and lowered crowding.

The seismic design of solid reinforced concrete bridge columns has been committed to, based on accumulated research and design specifications. The rational confinement model and seismic performance evaluation, however, are insufficient because of the lack of domestic and foreign design specifications about the experimental and analytical difficulties in the case of circular hollow reinforced concrete columns. In this paper, the seismic behavior of circular hollow reinforced concrete columns and its dependence on design variables are understood and explained. These research results can be used to derive the rational and economical design specifications for circular hollow sectional columns based on the result from the nonlinear analysis program, named RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology).

Unlike structures in the air, the vibration analysis of a submerged or floating structure such as offshore structures is possibly only when the fluid-structures is understood, as the whole or part of the structure is in contact with water. Through the comparision between the experimental result and the finite element analysis result for a simple cylindrical model, it was verified that an added mass effects on the cylindrical structure. Using the commercial FEA program ANSYS(v.11.0), underwater added mass was superposed on the mass matrix of the structure. A frequency response analysis of forced vibration in the frequency considered the dynamic load was also performed. It was proposed to find the several important modes of resonance peak for these fixed cylindrical type structures. Furthermore, it is expected that the analysis method and the data in this study can be applied to a dynamic structural design and dynamic performance evaluation for the ground and marine purpose of power generator by wind.

This study was conducted to investigate the effective ratio of Sulgidduk to steaming chesnut powder. I measured the sensory and mechanical characteristics, moisture content and color values of Sulgidduk added by different amount 4 of types of steaming chestnut powder; 0% (Control-0 group), 1% (CP-1 group), 2% (CP-2 group), 3% (CP-3 group), 4% (CP-4 group). Moisture content of Sulgidduk with steaming chestnut powder ranged from 38.53% to 46.05%. The L-value and b-value of the color decreased with an increase in steaming chestnut powder; however, a-value of the color decreased with an increase in steaming chestnut powder. As a result of analysis the texture of Sulgidduk steaming chestnut powder, it's hardness, springiness was increased. According to the sensory evaluation, CP3 had the highest values in texture and overall acceptability. Based on the result, it's considered that the most desirable ratio is steaming chestnut powder CP3. The results of the study supported the benefits of steaming chestnut powder supplementation in Sulgidduk in the aspects of taste and functionality. The degree of further increase in Sulgidduk with steaming chestnut powder without causing an adverse quality effect, remain for future study.

This study is a neutron activation for concrete that shields medical linear accelerator facilities. Comparison of general concrete and low activation concrete. The simulation method was simulated using MCNPX (Ver. 2.5.0) and FISPACT-2010, and the shielding ability for photon and neutron beams was calculated and neutron activation evaluation was carried out. As a result, the shielding capacity was 20 ~ 50 cm efficient in general concrete, and activate evaluation in low activation concrete was calculated to be low in radioactivity concrete, but all were estimated to not exceed their own allowable concentration in self - disposal. As a result of the comprehensive analysis, it is considered effective to use ordinary concrete.

The Educational Restitution Rate is an important parameter that determines the quality of university education. This paper analyzed data from 148 private universities over the 10 years from 2009 to 2018 using data mining techniques in Korea. A significant causal relationship is detected in the fixed effect model as a result of the panel estimation. And the scale of faculty expansion and fund management, which are the university evaluation indicators, and the size of basic funds, respectively, have a positive effect on the ERR, which is within the confidence interval. In the analysis, the more private universities improve the tuition dependence rate, the more decisively positive affecting ERR. As a result of nonparametric regression estimation, when the faculty expansion ratio is reinforced, the effect of economies of scale is detected in some sections, the improvement of the tuition dependence rate, and the result value is generated through the improvement that results are derived at a certain point in time. We hope that the university based on this study can be a basic Indicators for the diagnosis of basic competencies and policy of student-centered education.

Fire hazard and risk analysis at Nuclear Power Plants is implemented on the basis of the normal operational configuration. This steady configuration, however, can be changed due to the temporary displacement of equipment, electric cable and irregular movement of workers through the fire compartments when the on-line maintenance is processed during the power operation mode or the scheduled outage mode for the refueling. With the consequence of this configuration change, the fire analysis condition and the evaluation result will be different from those that were analyzed based on the steady configuration. In this context, at this paper, the general items for the reassessment are categorized when the configuration has changed. The contemporary zone models for the detail fire analysis are also illustrated for their application for each classified condition.
