Developers of network games have used several prediction techniques for hiding transmission delay to support the real-time requirement of network games. Nowadays many researches that are related with network game are in progress to solve delay problems more radically, such as to propose new routers architecture and transport protocols suitable to characteristics of network game traffic. So for these advanced researches the tasks to grasp the traffic characteristics of a network game are needed. In this paper we aimed to capture the traffic of MMORPG and present the statistical analysis of measured data. The measurement and the analysis were accomplished with the server of 'Lineage' that regarded as the most successful MMORPG. Next, we have implemented a traffic generator that reflects the characteristics of MMORPG and shown that the trace generated by MMORPG traffic generator had identical characteristics with actual traffic using statistical testing method. We expect that this traffic generator can be used in many researches related with a network game.

The purpose of this study is to develop an academic listening curriculum based on core competency. Traditionally, since learning involved obtaining static and absolute knowledge and skills, the structure of knowledge played a major role in the curriculum. However, a rapidly changing society requires efficient problem-solving abilities regardless of circumstances. Therefore, attention has now shifted to core competencies in developing curricula. First, in order to develop a Korean academic listening curriculum, the concept and traits of core competencies will be revisited. Second, we will identify implications from the cases of curricula based on core competencies and establish the direction of developing our curriculum. Third, we will show how the Korean academic listening curriculum of Sungkyunkwan university is developed based on the core competency approach.

The purpose of this research is to explore the levels of luxury-frugality consumption of the female consumers and classify their types on luxury-frugality consumption behaviors. Total of 479 on-line questionnaires were surveyed nationwide for this research in February, 2012. Statistical analysis was achieved by using t-test, one-way ANOVA, Duncans multiple range test, x², and Ward hierarchical cluster analysis with a total of 479 questionnaires. The research results are summarized as follows: First, the overall luxury-frugality consumption average mark of female consumers was 2.44. Second, all surveyed female consumers were classified into four types based on the means scores of two dimension luxury-frugality consumption behaviors. A total 26.51% of female consumers belonged to Type 1 (named as luxury consumption group) where females scored high points on two dimension luxury consumption behaviors. Type 2 (named as excessive consumption group) occupied 32.78% and this group scored low on the luxurious consumption but high on the overconsumption. Type 3 (named as prefer prestige group) occupied 28.39% and this group scored low on the overconsumption but high on the luxurious consumption. Type 4 (named as frugal consumption group) had 12.32% of females whose scores of two dimension luxury-frugality consumption behaviors were low.

본 연구는 학문 목적 한국어 말하기 평가(코스탭)가 실제적인 맥락에서 유학생의 학문 목적 말하기 과제 수행에 대한 정보를 제공하는 것과 관련하여 외삽 추론의 타당성을 갖추고 있는지를 알아보는 것을 목적으로 한다. 이를 위하여 논증 기반 타당화 체계 가운데 외삽 추론의 논증 구조를 수립하고, 툴민의 논증 요소를 기반으로 이를 검증하기 위한 연구를 설계하였다. 외삽 추론의 타당도 증거는 이론적인 검토와 코스탭 결과와 실제 목표 영역에서의 학습자의 수행 결과의 비교를 통해 수집되었다. 연구 참여자인 유학생은 모의 수업 상황에서 강의를 듣고 그에 관한 말하기 과제를 수행하였다. 분석 결과 코스탭과 실제 말하기 과제 수행 간에 보통 수준의 상관이 나타났으며, 이는 기존의 교육 측정 및 언어 평가 이론의 지지와 함께 대학 강의 맥락과 관련하여 실제적인 학문 목적 말하기 능력을 평가하는 도구로서 코스탭이 기능할 수 있음을 보여준 것이다. 또한 타당화 과정에서 확인한 코스탭 본 검사 결과, 기준 설정 결과에 따른 수학 가능성 평정과의 유사성 증거 등은 향후 코스탭의 유용성과 활용 가능성을 보여준다. This article investigates the extrapolation inference for the Korean Speaking Test for Academic Purposes(KoSTAP) in relation to providing information on the performance of international students in academic speaking tasks in practical contexts. The Argument schemes of extrapolation inference and validation study were designed based on the argument-based approach. Evidence of extrapolation inference was collected by comparing the KoSTAP scores with learners’ performance in the real-world target domain. International students who participated in this study, listened to a lecture in a simulated class and performed related speaking tasks. The extrapolation inference was verified by analyzing the correlation between the result of the speaking task evaluation and the KoSTAP score. This study shows that KoSTAP functions as a tool to evaluate the practical academic speaking skills required by universities in relation to the lecture context. It also presents the future usefulness of KoSTAP.

항산화 물질을 함유하고 있는 HSC를 첨가한 숙면의 물리화학적 특성을 확인하였다. 열수추출을 이용하여 제조된 HSC의 함량에 따라 조직감과 인장도, DPPH radical 소거능, 색도의 변화를 관찰하였으며, HSC가 포함하고 있는 변성 단백질 및 펩타이드와 밀가루와의 cross link작용으로 인해 HSC를 첨가할수록 인장도가 커짐을 확인하였다. 또 한 HSC 함량은 DPPH radical 소거능에도 유의적인 영향을 미쳤으며, 이는 해삼이 가지고 있는 여러 비타민과 페놀화합물, 카로티노이드계 물질들을 함유하고 있기에 항산화 검사에서 유의적인 차이를 보였다. 혼합물 설계법 (mixture design)을 적용하여 HSC 제면 혼합비를 최적화하였으며, 요인은 밀가루, 물, HSC로 설정하였고, extreme vertices (꼭지점 법)에 의해 혼합비를 달리하여 제조하였다 반응값으로 인장도(tensile test), DPPH radical 소거능, 조 직감(TPA), 색도를 측정하였고, 반응값의 결과를 확인하여 유의적인 차이를 나타내는 인장도와 DPPH radical 소거능 만을 이용하여 최적 배합비를 도출하였다. 인장도는 HSC 이 첨가되더라도 레올로지 특성치를 유지시켜주는 범위를 설정하기 위해 일반 밀가루 면의 인장도에서 5% 내외로 설정하였으며, DPPH radical 소거능은 최대화하였다. 그 결과 최적화된 HSC 제면 혼합비는 밀가루 69.27% (w/w), 물 22.48% (w/w), HSC 7.05% (w/w)로 나타났다. Sea cucumber (SC) or Stichopus japonicas is widely used in East Asia as a traditional medical component for the treatment of asthma, arthritis, and sinus congestion. The hydrolysate of SC (HSC) after treatment with a protease is also widely used as an ingredient for processed food application such as noodles. Tensile force and deformation are important texture properties of noodle. The peptides prepared by hydrolyzing SC could affect the tensile properties of noodle, as well as DPPH radical scavenging. The objectives of this study were to characterize the tensile properties, the texture properties, color, and DPPH radical scavenging of noodle with HSC and to determine an optimum formulation of dough with HSC for noodle. The HSC was prepared by hydrolyzing dried SC powder with distilled water (DW) and a protease, Protamex (Novozyme Nordisk, Bagsvaerd, Danmark). The tensile properties and antioxidant activity were used as major constraint functions for the optimization. The optimum ratio was determined as flour:water:HSC=69.27:22.48:7.05 (w/w). Increasing the amount of HSC in the formulation increased the tensile force but no significant difference was observed in the deformation.

This study aims to classify the type of financial support behavior of mothers for elementary school children and analyze the characteristics shown by child support motivation, standard setting, and support satisfaction. The final 798 copies were used for data analysis. Women with elementary school children nationwide were surveyed through online surveys. Among the different types of financial support behavior, ‘active support type’ had the strongest motivation for social contribution and internal control. The mothers recognized that they had enough resources, they properly set goals for child support, and were very satisfied with the performance of child support. The ‘planning performance type’ had the strongest motivation for supporting learning needs. The mothers had a very weak perception of the sufficiency of economic resources, but had a high goal setting and overall standard setting, and high satisfaction with performing child support. The ‘information exploration type’ was very low in the motivation for supporting learning needs and the goal setting for supporting children, and the satisfaction level of support for children was moderate. The ‘priority type’ had a relatively high internal control motivation. Mothers had a very low perception of the sufficiency of economic resources and overall resources, low goal setting, overall standard setting, and low satisfaction with child support. In the ‘polar support type’, the motivation for social contribution and internal control were relatively low. The perception that economic and overall resources were sufficient was very low, and the satisfaction of setting goals for child support and performing child support was very low.
