허구서사 애니메이션 감상 경험에 있어 관객의 몰입은 작품의 성패를 결정하는 중요한 요소다. 특히, 대중 애니메이션의 경우, 흥행성공과 같은 사회경제적 성취 이외에도 관객의 몰입은 작품성 성취의 중요한 전제조건이 된다는 점에서 연구의 필요성이 제기된다. 허구서사 애니메이션은 이야기가 (소리를 포함한) 이미지로 서술된다는 특성에 최근 2D 애니메이션에 비해 질료적 사실주의를 강조하는 3D 형식이 보편화된 현상까지 더해져, 서사체 텍스트와 가상현실의 수용자 몰입 방식을 일정부분 공유한다고 볼 수 있다. 즉, 작품 텍스트 안에 몰입을 견인하는 요소가 내재되어 있다는 관점과, 매체의 물리적 특성이 수용자를 몰입하도록 강제한다는 이론 가운데 놓여있다. 어떤 경우에도 몰입하는 주체는 관객이므로, 허구서사 애니메이션에의 몰입에 대한 연구에 가장 유용한 이론은 작품(성) 분석이나 시청각 효과에 대한 연구보다 텍스트-관객의 관계를 중심에 둔 구성주의 인지서사학적 접근이라고 볼 수 있다. 본 연구는 서사에 대한 수용자의 몰입에 대한 기존의 연구를 구성주의 인지서사학을 중심으로 검토하고 애니메이션의 특수성에 적용하여, 관객을 작품에 몰입하게 만드는 애니메이션의 요인과 특성을 연구하였다.

A spot welded structures have an influence on a diverse climatic situation, for instance temperature, humidity and precipitation. In addition factors of environmental pollution such as acid rain, that courses corrosion, have the tendency to increase. But spot welded structures strength is affected by humidity and environment temperature. Therefore, it is important to evaluate effect of temperature and water immersion on strength properties of spot welded part. In this study, the strength distribution of spot welded plates is evaluated the environmental temperature of zinc coated steel plates. Test is conducted with welded part immersed in distilled and synthetic sea water. Specimens are immersed into water for 10, 100, 500 and 1000 hours to evaluate the offsets of water immersion time on tensile-shear strength under the conditions of -40, 0, 20 and 5$0^{\circ}C$. From this result, spot welded specimens with 5 mm clearance have lower tensile-shear strength in the distilled water or synthetic sea water than without clearance. And they have lower tensile-shear strength under -4$0^{\circ}C$ and over 5$0^{\circ}C$.

This study explored the effects of water or brine (2% NaCl, w/v) immersion thawing combined with ultrasound treatment (40 kHz, 150 W) on the quality characteristics of pork. Ultrasound treatment of pork was conducted in two cold media (at $4^{\circ}C$), water and 2% (w/v) brine, respectively. Because the ultrasound treatment caused temperature increase in the media from $4^{\circ}C$ to $16^{\circ}C$, the qualities of pork thawed by ultrasound were compared with those thawed by immersion either in water or brine where the temperature was being maintained at either $4^{\circ}C$ (low temperature control) or $17^{\circ}C$ (high temperature control). The ultrasound treatment resulted in rapid thawing of pork where the thawing rate was similar to those thawed in the $17^{\circ}C$ media. For quality characteristics, ultrasound-treated pork in brine had an advantage of less cooking losses when comparing to the control. In particular, ultrasound treatment in brine exhibited the lowest shear force (or highest tenderness) among the freezing/thawing treatments. Although the ultrasound processing in brine caused discoloration of the pork, this thawing technique had potential to be applied as a commercial thawing technology for frozen foods.

The present study investigated the effect of zincate treatment time on the dissolution behavior and the deposition of copper by immersion process and electroplating process on AZ31 Mg alloy substrate in a copper pyrophosphate bath. Without zincate pretreatment, the AZ31 Mg substrate quickly dissolved in the copper pyrophosphate solution although an external cathodic current was applied. The copper layers deposited on non-zincate treated AZ31 Mg alloy substrate by both immersion and electroplating processes showed very porous structure and very poor adhesion. With increasing zincate treatment time up to 2 min, the dissolution of AZ31 substrate in pyrophosphate solution rapidly decreased and the deposited copper layer was less porous and exhibited stronger adhesion. The immersion of AZ31 Mg sample in zincate solution for 5 min was found as a critical time for producing a non-porous and adherent electrodeposited copper layer on AZ31 Mg alloy. The optimum zincating time can be determined by observing the open circuit potential (OCP) of AZ31 Mg alloy samples in a copper pyrophosphate electroplating bath. The OCP reached a stable value of about -0.10 V (vs. SCE) after 5 min of immersion in the copper pyrophosphate electroplating solution.

In this study, we evaluated the efficiency of chemical marking of black rockfish scales by immersion in oxytetracycline hydrochloride (OTC, 500 ppm), alizarin red S (AR, 250 ppm) and calcein (CARL, 250 ppm) diluted rearing water. Immersion treatment of chemicals had no effects on both mortality and growth of black rockfish. Marking sucess was 100% in all treatment durations (24, 48 and 72 hours) with three chemicals and marking quality was higher in 48 and 72 hours than 24 hours treatment. Marking retention rates at 24 weeks after treatment were 100% in OTC and CAL treated group, but marking quality was higher in CAL treated group (brilliant 92%, bright 8% and dim 0%) than in OTC treated group (brilliant 4%, bright 70% and dim 26%). AR treated group had lower marking retention rates and marking quality than OTC and CAL treated group. As a results, immersion treatment with OTC and CAL was effective in marking scales of black rockfish and practical in releasing program and other studies requires same rearing environment.

This study aims to examine how motivational constructs are interrelated with social, context-specific factors and, as a result, contribute to L2 writing achievement within the framework of self-determination theory. The data consisted of 67 Korean college students' questionnaire responses, final scores in an on-offline blended writing course, and qualitative interviews with 5 students. In the descriptive and the correlation analyses, the participants' extrinsic motivation was found higher than intrinsic motivation, with low amotivation. Among social factors, immersion environment, foreign instructor, and peer comparison marked high scores, whereas Korean instructor and online material gained low scores. Those contextual factors were interrelated with each other, such that the immersion factor correlated significantly with Korean instructor and peer comparison. Extrinsic and intrinsic motivational subscales engendered strong correlations with the high-scored social factors, i.e., immersion, foreign instructor, and peer comparison, which were also closely interrelated with L2 writing achievement. The findings illuminate intricate workings of motivation in its effects on L2 achievement and corroborate the roles of contextual factors. The effect of motivational subscales on achievement may be valid through interplay with some social factors. The dynamics of motivation is discussed for pedagogical applications.

Preliminary experiment was peformed to investigate the leaching characteristics of paraffin waste forms that had been recently generated in large quantities at domestic nuclear power plants. At first, waste simulants whose compositions were different in mixing ratio of paraffin to boric acid were prepared. Their compressive strengths were measured and ninety-day leaching test of specimen including cobalt was carried out according to ANSI/ANS-16.1 test procedure. Water immersion test was also conducted keeping pace with leaching test and the weight change and the compressive strength of specimen were observed after ninety days. The compressive strength of waste form exhibited 666 psi (4.53 MPa) in the case where mixing ratio of boric acid to paraffin was 78/22, which was adopted in concentrate waste drying system of domestic nuclear power plants. The leaching test resulted in about 50% of the cumulative fraction leached for boric acid and cobalt, respectively. The specific gravity of waste form was 0.87 ［g/g］whose value was less than that of water because the weight loss of about 39% occurred after the water immersion test of ninety days. It was also observed that the waste form which had undergone ninety-day water immersion test exhibited the compressive strength of 203 psi (1.38 MPa).

Amino-carboxyl acid as a complexing agent in acid copper sulfate solution was utilized to improve the adhesion of immersion copper layer for steel wire. According to the tape test results, regardless of alloy composition of the wire, the adhesion of immersion copper layer was improved with the addition of amino-carboxyl acid. The incorporation of H and Fe in the plating layer was analyzed by TOF-SIMS. The H and Fe were detected at the entire coating layer without any addition of amino-carboxyl acid. However, with addition of amino-carboxyl acid, the H and Fe were scarcely detected at the coating layer.
