노무현·이명박 대통령의 대일외교는 공통적으로 임기초반 협력적 관계에서 중·후반으로 갈수록 양국 관계가 경색되는 패턴을 보였다. 두 정부의 패턴변화에 주목해 한일 관계의 갈등 상황이나 원인을 밝히는 연구들이 시도되어왔지만, 일본 내 정치구조변화와 한국의 과잉대응에서 그 요인을 찾는 등 연구대상이나 연구경향이 제한적이었다. 이 논문은 외교정책결정 맥락과 연계되어있는 노무현·이명박 대통령의 외교신념에 대해 분석했다. 두 대통령의 대일 외교신념은 그들의 외교정책결정 행위에 영향을 줄 것을 전제하고, 외교신념과 실제 외교행위와의 관계를 밝히고자 했다. 노무현·이명박 대통령의 대일외교신념과 독도 분쟁과정에서 외교행위의 운영코드 유형 분석을 통해 신념과 행위사이에 유사성이 존재한다는 것을 발견했으며, 이들의 전략성향이 유사한 결과를 보였다. 또한 다른 환경의 두 대통령이 유사한 대일외교 패턴이 도출된 것에 관해 개입되는 상황적 요인의 작용에 대해서도 살펴봤다. 일본의 도발과 권력자원의 감소, 그리고 반일정서 확산으로 인한 정부대응변화에 관한 국내요구는 두 대통령의 대일외교 기조를 전환하고, 강경한 행위변화를 이끌어내는 동력으로 작용했음을 확인하였다. The foreign policies of President Roh Moo-hyun and Lee Myung-bak towards Japan showed a common pattern in which the diplomatic relations between Korean and Japan shifted from cooperative relations in the early years of office to conflict in the latter half. Although there has been some research conducted to analyze the bilateral conflicts and their causes focusing on such change in the patterns of the two governments, the subjects and patterns of such research have been limited to, for example, focusing only on change in the political structure of Japan and Korea’s overreaction. This paper analyzed the diplomatic beliefs of the two presidents that are linked to their decisions on foreign policies. The goal of this study is to analyze the relationship between the two presidents’ beliefs and their actions on the premise that their diplomatic beliefs towards Japan affect their decisions on foreign policies. By analyzing the operational codes of the two presidents' beliefs towards Japan and their diplomatic responses during Korea-Japan dispute over Dokdo, this study had found that there was a link between their beliefs and actions while their strategic propensities showed similarities. This paper also looked at the effects of situational factors that may have affected the two presidents in different circumstances to have similar diplomatic patterns towards Japan. This study has confirmed that external stimulus like Japan's provocation, a decrease in political resources, and the domestic call for a change in government responses with widespread anti-Japan sentiment served as a driving force for the two presidents to change their stance on their foreign policies towards Japan and to take bold action for change.

The purpose of this study were to test the mediating effects of emotions and task persistence in the relationship between teacher-student interactions in dance classes. Subjects were 794 middle school students. Data were conducted using correlations, one-way MANOVA, structural equation modeling, and multi-group analysis. The results of structural equation modeling are as follows; First, dance teacher’s proximity perceived by students in classes had a positive impact on competence enhancement via positive emotional experience and task persistence. Second, dance teacher’s strict influence perceived by students in classes was directly inclined to evoke negative emotions and to decrease students’ perception of competence. Third, the effects of teacher- student interaction in dance classes on students’ competence via positive emotion and task persistence was invariant across gender. These findings were discussed in relation to implications of the study and directions for future research.

In this paper, a 2-degree-of-freedom (DOF) Micro-electro-mechanical systems(MEMS) scanning micromirror array is fabricated, which has a large area mirror, a large actuation displacement and high fill factor. Each mirror is designed for independent actuation to two axis. The mirrror is designed as leverage structure in order to achieve large actuation angle with electrostatic actuator. To achieve this, a vertical combdrive actuator is fabricated with leverage structure. The tilting angles are 9.87 ° and 9.76 ° for each axis at the voltage of 150 V. The high fill factor is accomplished by fabricating actuator under the mirror plate. The array is composed of 9 single mirrors with 3 by 3 matrices, of which the size is 1 ㎜ by 1 ㎜. The fill factor of mirror array is 84 %.

We present the design and fabrication precess of a two-axis tilting micromirror device driven by the electrostatic vertical comb actuator. A high aspect-ratio comb actuator is fabricated by multiple DRIE process in order to achieve large scan angle. The proposed fabrication process enables a mirror to be fabricated on the wafer-scale. By bonding a double-side polished (DSP) wafer and a silicon-on-insulator (SOI) wafer together, all actuators on the wafer are completely hidden under the reflectors. Nickel lines are embedded on a Pyrex wafer for the electrical access to numerous electrodes of mirrors. An anodic bonding step is implemented to contact electrical lines with all electrodes on the wafer at a time. The mechanical angle of a fabricated mirror has been measured to be 1.9 degree and 1.6 degree, respectively, in the two orthogonal axes under driving voltages of 100 V. Also, a 8 × 8 array of micromirrors with high fill-factor of 70 % is fabricated by the same fabrication process.

고문헌에 기록된 사라진 우리술을 발굴하는 전통주 복원프로젝트의 일환으로서 시판 누룩 5종을 사용한 석탄주(惜呑酒)를 제조하여 이들의 양조적성을 구명하였다. 석탄주 발효 중 품온변화 등 일반성분을 분석하였고 완성된 석탄주(발효기간 10일)의 관능평가를 실시하였다. 전체적으로 술덧의 품온변화는 실내온도 변화에 상응하였다. pH는 전체적으로 발효 0~3일차까지 급격히 떨어졌다가 발효 중간부터 완만히 증가(3일: 3.13~3.57, 6일: 3.35~3.80)하였고, 발효 종료 시, pH 3.60~4.05로 상승하였다. 산도는 전반적으로 높았으며(0.45~0.59%) Nuruk-B의 수치가 가장 높았다. 이는 누룩에 생육하는 유기산 생성 곰팡이와 젖산균이 술덧의 적절한 온도, 원료 조성, 효모 수에 따라 유기산 생산능에 차이가 있는것으로 보여진다. 환원당과 당도는 Nuruk-C로 제조한 석탄주에서 가장 높았으나(5.36%, 23o) 알코올 함량(8.6%)은 가장 낮았다. 5종의 시판누룩으로 발효시킨 석탄주에서 Nuruk-A가 알코올 함량(19.4%)이 가장 높았고 휘발산은 발효 3일째 가장 높은 수치(132.6~263.7 ppm)를 나타내었으나, 발효가 진행되면서 급격히 감소(5.25~5.94 ppm)하였다. 관능평가는 5점 척도법으로 실시하였으며 Nuruk-D로 제조한 석탄주가 전반적인 기호도가 가장 높았고(4.0), Nuruk-A의 경우 가장 낮았다(2.77). We investigated quality characteristics of Seoktanju (one of the Korean traditional rice wine) which was fermented using five kinds of Korean commercial Nuruks. The purpose of this study was to research what effects on the quality of Seoktanju by using different Nuruks. We analyzed general component such as each mash`s temperature change patterns, pH, titrable acidities, reducing sugar contents, volatile acids, and sugar contents during fermentation periods and studied sensory evaluation of produced Seoktanju (10 days). On the whole, temperature change patterns in the each mashes were depend on room temperature. All Seoktanju`s pH was reduced rapidly up to three days after first mashing (pH 3.13-3.57) and after that was increased gradually. The end of fermentation pH was pH 3.6-4.05. Mostly, acidities were indicated high(0.59%) and Nuruk-B was showed highest acid value. These results seems to be different as occasion organic acids producing activity depend on the number of yeast, material contents, optimal temperature in the each mashes by fungi and lactic acid bacteria in Nuruks. In reducing sugar contents and sugar contents, Nuruk-C treatment were showed the highest value with 5.36%, 23o brix, respectively and alcohol content was lowest with 8.6%. In the five kinds of reproduced Seoktanju, alcohol content was the highest in the treated Nuruk-A group. Volatile acid value was the highest with 132.6~263.7 ppm at the 3 day after first mashing day but as the fermentation time goes on, it was reduced sharply by 5.25~5.94 ppm. Sensory evaluation was performed with 5 point scale, the Seoktanju using Nuruk-D was presented by 4 point, while Nuruk-A was presented lowest by 2.77 point on overall acceptability.

The remarkable development of Korea's relationship with China has raised interesting social scientific questions from various angles. Yet, the paradoxical phenomenon of low favorability toward China among Korean people has not received extensive serious investigations thus far. A few extant studies have some problems in terms of operationalizing dependent variable and snapshot perspective. This article explores the pattern and sources of low favorablity toward China while Korea has deepened its economic interdependence for the period of 2003-2013. The empirical findings include (1) those who have negative view toward North Korea sustain lower favorability toward China. (2) Young generation (eco-generation) has even lower favorability toward China than Korean-war generation who has suffered the tragedy of the War. (3) Those who have higher education have lower favorability toward China. These empirical outcomes provide have laid ground for further investigation in theoretical as well as in practical terms.
