The expectation and confirmation emerging as one of problem-solving strategies in the elementary school is a strategy that does not limited in the elementary school but used in the middle and high school. This strategy inevitably requires a process of adjustment that affected by the earlier expectation. Such an adjustment raised expectation and confirmation to one of effective problem-solving strategies. The adjustment is especially important to carry out the strategy effectively. The aim of this study was to conduct basic research on cognitive characteristics appearing to students when they carried out the expectation and confirmation strategy. We investigated and analyzed this in term of adjustment of expectation. To do this, we examined 50 5th graders' response in three kinds of word problems and interviewed with 4 participants who is using the expectation and confirmation strategy. The interview was conducted by using the items or solutions used in the test. From this, we tried to check students' cognitive characteristics and recognition on it's value. Furthermore we proposed the pedagogical implications associated with these results.

The interactions between people who do not know each other have been greatly increased with the on-going increase of people's cyberspace activities. In this situation, there exist potential risk factors such as the possibility of fraud, so we need a method to reduce or eliminate those risk factors. Concerning this necessity, rating systems are widely used, and many trust metrics calculated from rate values that people give to each other are proposed to help them make decisions. However, the trust metrics decrease the accuracy, and this is caused by the different rating scales and ranges of each person. So, we propose a fuzzy adjustment method to solve this problem. It is possible to catch the exact meaning of the trust value that each person selects through applying fuzzy sets, which improve the accuracy of the trust metric calculated from the trust values. We have applied our fuzzy adjustment method to the TidalTrust algorithm, a representative algorithm for calculating the local scalar trust metric, and we performed an experimental evaluation with four data sets and three evaluation methods.

This article recapitulates the recent changes in trade laws, which may be accentuated due to the intriguing emergence of fortified protectionism and Mega FTAs. It points out the need to formulate not only the corporate strategy for enhancing the product differentiation and architectural capabilities but also the public policy, which comprises the industrial adjustment policy to cope with possible negative impulses caused by the digital trade and foreign direct investment. It is imperative for Korea to facilitate the alignment between corporate strategy and industrial adjustment policy as an effective means of enhancing industrial structure by nurturing those linkage effects between relevant forward and backward industries. Given the drastically volatile trade norms of multi-track trade policies, it may be a pivotal momentum for Korea to pursue a paradigm shift of its trade policy with a prime objective of achieving such an alignment between corporate strategy and industrial adjustment policy, which affords increased value-added and the further development of product or generic technology instead of resorting to the misuses and abuses of economies of scale and production technology for the maximization of export amount.

Approximately 70% of Korea is composed of forest areas. Especially 48% of agricultural field is practiced at highland areas over 400 m in elevation in Kangwon province. Over 90% of highland agricultural farming is located at Kangwon province. Runoff characteristics at the mountainous area such as Kangwon province are largely affected by steep slopes, thus runoff estimation considering field slopes needs to be utilized for accurate estimation of direct runoff. Although many methods for runoff estimation are available, the Soil Conservation Service (SCS), now Natural Resource Conservation Service (NRCS), Curve Number (CN)-based method is used in this study. The CN values were obtained from many plot-years dataset obtained from mid-west areas of the United States, where most of the areas have less than 5% in slopes. Thus, the CN method is not suitable for accurate runoff estimation where significant areas are over 5% in slopes. Therefore, the CN values were adjusted based on the average slopes (25.8% at Doam-dam watershed) depending on the 5-day Antecedent Moisture Condition (AMC). In this study, the CN-based Long-Term Hydrologic Impact Assessment (L-THIA) direct runoff estimation model used and the Web-based Hydrograph Analysis Tool (WHAT) was used for direct runoff separation from the stream flow data. The $R^2$ value was 0.65 and the Nash-Sutcliffe coefficient value was 0.60 when no slope adjustment was made in CN method. However, the $R^2$ value was 0.69 and the Nash-Sutcliffe value was 0.69 with slope adjustment. As shown in this study, it is strongly recommended the slope adjustment in the CN direct runoff estimation should be made for accurate direct runoff prediction using the CN-based L-THIA model when applied to steep mountainous areas.

본 연구는 치위생과 학생들이 효과적으로 자기조절학습을 하기 위한 성취목표지향성을 파악하고 이러한 적응적인 성취목표지향을 유도하기 위한 수업 환경을 제안하고자 대구 충북지역의 소재하는 치위생과 재학생 387명을 대상으로 성취목표 지향성 및 자기조절학습 능력 및 영향력을 일원다변량분석과 다중회귀분석을 이용하여 알아보았다. 전체 여대생들의 $2{\times}2$ 성취목표지향성 가운데 숙달접근이 가장 높은 것으로 나타났으며, 다음으로 수행접근, 숙달회피, 수행회피 순으로 높게 나타났으며, 학년에 따른 동기조절의 경우 1학년의 내재적 가치가 2학년과 3학년의 내재적 가치에 비하여 높았고, 행동조절에 있어서 3학년의 시간과 공부조절, 조력추구는 1학년과 2학년의 시간과 공부조절에 비하여 높은 것으로 나타났다. 다음으로 $2{\times}2$ 성취목표지향성의 하위변인은 자기조절학습의 하위변인과 정적상관관계를 보이는 것으로 나타났는데, 하위변인 가운데 숙달접근은 내재적 가치와 상관관계가 가장 큰 것으로 나타났고, 숙달회피, 수행접근, 수행회피는 외현적 목표지향과 상관관계가 가장 큰 것으로 나타났다. 한편, 자기조절학습의 하위변인 가운데 내재적 가치, 외현적 목표지향, 공부환경조절의 경우 $2{\times}2$ 성취목표지향성의 모든 하위변인과 통계적으로 유의미한 상관관계가 있는 것으로 나타났으며, 자기조절학습의 하위변인은 $2{\times}2$ 성취목표지향성의 하위변인 가운데 숙달접근과 가장 큰 상관관계가 있는 것으로 나타났으며, 숙달접근, 숙달회피, 수행접근, 수행회피가 동기조절의 하위변인에 통계적으로 유의미한 영향을 미치는 것으로 나타났다. 인지조절에 영향을 미치는 요인은 학년과 숙달접근이 인지조절의 하위변인에 유의미한 영향을 미치는 것으로 나타났으며, 행동조절에 영향을 미치는 요인은 학년과 숙달접근이 행동조절의 하위변인에 유의미한 영향을 미치는 것으로 나타났다. 결론적으로, 성취목표지향성과 자기조절 학습의 영향력을 분석함으로써 학생들의 학업목표의 방향을 수정하고 적절한 자기조절학습의 사용을 통해 학습을 효과적으로 할 수 있음을 시사한다. 하지만 본 연구에서는 학업 성취적 요인을 분석대상으로 삼지 않았기 때문에 보다 직접적인 결론을 도출할 수 있는 없었지만 성취목표지향성과 자기조절학습은 서로 상관성이 높기 때문에 성취목표지향성에 따라 자기조절학습이 달라질 수 있으며 두 요인을 잘 고려하면 학습자들의 성취동기를 유발하고 효과적인 학습과정을 유발할 수 있다는 기초자료가 될 수 있으리라 생각된다. 후속연구로 구체적인 학업성취도와의 관련성을 탐색하여 성취목표 지향성의 하위변인과 자기조절학습능력 및 학업성취도의 구체적인 관련성을 연구할 필요가 있다고 생각된다.

With population growth, industrialization, and urbanization within the watershed, the hydrologic response changed dramatically, resulting in increases in peak flow with lesser time to peak and total runoff with shortened time of concentration. Infiltration is directly affected by initial soil moisture condition, which is a key element to determine runoff. Influence of the initial soil moisture condition on hydrograph analysis should be evaluated to assess land use change impacts on runoff and non-point source pollution characteristics. The Long-Term Hydrologic Impact Assessment (L-THIA) model has been widely used for the estimation of the direct runoff worldwide. The L-THIA model was applied to the Little Eagle Creek (LEC) watershed and Its estimated direct runoff values were compared with the BFLOW filtered direct runoff values by other researchers. The $R^2$ value Was 0.68 and the Nash-Sutcliffe coefficient value was 0.64. Also, the L-THIA estimates were compared with those separated using optimized $BFI_{max}$ value for the Eckhardt filter. The $R^2$ value and the Nash-Sutcliffe coefficient value were 0.66 and 0.63, respectively. Although these higher statistics could indicate that the L-THIA model is good in estimating the direct runoff reasonably well, the Antecedent Moisture Condition (AMC) was not adjusted in that study, which might be responsible for mismatches in peak flow between the L-THIA estimated and the measured peak values. In this study, the L-THIA model was run with AMC adjustment for direct runoff estimation. The $R^2$ value was 0.80 and the Nash-Sutcliffe coefficient value was 0.78 for the comparison of L-THIA simulated direct runoff with the filtered direct runoff. However there was 42.44% differences in the L-THIA estimated direct runoff and filtered direct runoff. This can be explained in that about 80% of the simulation period is classified as 'AMC I' condition, which caused lower CN values and lower direct runoff estimation. Thus, the coefficients of the equation to adjust CN II to CN I and CN III depending on AMC condition were modified to minimize adjustments impacts on runoff estimation. The $R^2$ and the Nash-Sutcliffe coefficient values increase, 0.80 and 0.80 respectively. The difference in the estimated and filtered direct runoff decreased from 42.44% to 7.99%. The results obtained in this study indicate the AMC needs to be considered for accurate direct runoff estimation using the L-THIA model. Also, more researches are needed for realistic adjustment of the AMC in the L-THIA model.
