  • This study identifies methods to design patterns for jeans that are suitable for women in their twenties. Five patterns suggested by previous researchers were used to draw the same size of jeans (waist 67 and hip 91). The author compared and analyzed the measurements and shapes of the patterns, ranging from waist to crotch. Samples were produced based on these patterns and then tests were conducted to observe the dynamic functions and exteriors of the samples. The dynamic functions observed in this study include walking, ascending stairs, descending stairs and sitting on chairs. The results of the current study are as follow. The best evaluated pattern in terms of exteriors is the one where the hips and thighs are tightest compared to other patterns and where the back part is wider than the front part. This pattern also received high evaluations in dynamic functions due to comfort when walking. Regarding ascending or descending stairs, the tests found that all its parts (except the front crotch) are more comfortable than those of any other patterns. All these results show that a comfortable fit and easy movement is possible when the crotch width of the back is broader than the hip width so that the hips are comfortably supported.

  • Purpose: The purpose of this study was to investigate the effect of the number of measurement points on the calculation of transverse relaxation time (T2) with a focus on muscle T2. Materials and Methods: This study assumed that muscle T2 was comprised of a single component. Two phantom types were measured, 1 each for long ("phantom") and short T2 ("polyvinyl alcohol gel"). Right calf muscle T2 measurements were conducted in 9 healthy male volunteers using multiple-spin-echo magnetic resonance imaging. For phantoms and muscle (medial gastrocnemius), 5 regions of interests were selected. All region of interest values were expressed as the mean ${\pm}$ standard deviation. The T2 effective signal-ratio characteristics were used as an index to evaluate the magnetic resonance image quality for the calculation of T2 from T2-weighted images. The T2 accuracy was evaluated to determine the T2 reproducibility and the goodness-of-fit from the probability Q. Results: For the phantom and polyvinyl alcohol gel, the standard deviation of the magnetic resonance image signal at each echo time was narrow and mono-exponential, which caused large variations in the muscle T2 decay curves. The T2 effective signal-ratio change varied with T2, with the greatest decreases apparent for a short T2. There were no significant differences in T2 reproducibility when > 3 measurement points were used. There were no significant differences in goodness-of-fit when > 6 measurement points were used. Although the measurement point evaluations were stable when > 3 measurement points were used, calculation of T2 using 4 measurement points had the highest accuracy according to the goodness-of-fit. Even if the number of measurement points was increased, there was little improvement in the probability Q. Conclusion: Four measurement points gave excellent reproducibility and goodness-of-fit when muscle T2 was considered mono-exponential.

  • Individuals often make their judgments on the basis of the ease or difficulty with which information comes to mind (for reviews, see Greifeneder, Bless, and Pham 2010; Schwarz 1998, 2004). Recent research, however, has documented that variables known to determine the degree of cognitive resources invested in information processing such as personal relevance (Grayson and Schwarz 1999; Rothman and Schwarz 1998), accuracy motivation (Aarts and Dijksterhuis 1999), and processing capacity (Menon and Raghubir 2003) can affect the extent to which individuals draw on metacognitive difficulty in making their judgments. The primary aim of this research is thus to investigate whether individuals with substantial cognitive resources or those with lack of cognitive resources are more likely to draw on metacognitive difficulty when making their product evaluations. The findings from two laboratory experiments indicate that individuals who perceive a greater level of fit between their self-regulatory orientation and temporal construal (Experiment 1), and between their self-construal and the type of product benefit appeal (Experiment 2) are more likely than those who perceive the lack of such fit to evaluate a target product less positively after thinking of many rather than a few positive reasons. The findings provide supporting evidence for the two-stage backward inference process involved with the effect of metacognitive difficulty on consumer judgments in that consumer judgments based on metacognitive difficulty may require greater cognitive resources than those based on the content of information generated. Also, the current research documents further empirical evidence for the relationship between self-regulatory orientation-construal level fit and cognitive resources such that perceived regulatory-construal level fit can increase consumer willingness to invest cognitive resources into their judgment tasks. Last, the findings can help marketers differentiate purchase situations where asking consumers to think of many positive benefits from purchase situations where asking consumers to think of a few key benefits is relatively more beneficial.

  • 조절부합은 개인의 조절초점 성향과 평가 및 판단 전략이 지닌 조절초점이 서로 일치할 때 일어난다. 본 연구에서는 평가 및 의사결정의 영역이 유발하는 조절초점과 개인의 조절초점간의 부합이 평가에 영향을 미칠 것이라고 가정하고, 향상적 영역으로는 제품 디자인 평가를, 예방적 영역으로는 도덕적 평가를 사용하여 조절부합 효과를 알아보았다. 향상초점과 관련된 영역인 미적 제품에 대한 평가 과제를 사용한 실험 1에서는 향상초점인 사람들이 예방초점인 사람들에 비해 긍정적인 것은 더 긍정적으로, 부정적인 것은 더 부정적으로 평가하였다, F(1, 95) = 4.87, p < .05. 반면 금지와 규범적인 도덕 상황을 사용한 실험 2에서는 금지적 상황에서만 예방초점인 사람들이 향상초점인 사람들에 비해 도덕적으로 옳지 않은 결정에 대해서는 더 비 도덕적인 것으로 평가하였다, F(1, 139) 4.14, p < .05. 반면 규범적 상황에 대한 평가에서는 이러한 조절부합 효과가 나타나지 않았다. 이러한 연구결과는 평가 및 의사결정 영역과 관련해서도 조절부합이 나타날 수 있음을 보여준다.

  • Purpose : The purpose of this study was to evaluate the machining accuracy and consistency of implant/abutment/screw combination or internal connection type. Material and methods: In this study, each two randomly selected internal implant fixtures from ITI, 3i, Avana, Bicon, Friadent, Astra, and Paragon system were used. Each abutment was connected to the implant with 32Ncm torque value using a digital torque controller or tapping. All samples were cross-sectioned with grinder-polisher unit (Omnilap 2000 SBT Inc) after embeded in liquid unsaturated polyester (Epovia, Cray Valley Inc). Then optical microscopic and scanning electron microscopic(SEM) evaluations of the implant-abutment interfaces were conducted to assess quality of fit between the mating components. Results : 1) Generally, the geometry of the internal connection system provided for a precision fit of the implant/abutment into interface. 2) The most precision fit of the implant/abutment interface was provided in the case of Bicon System which has not screw. 3) The fit of the implant/abutment interface was usually good in the case of ITI, 3I and Avana system and the amount of fit of the implant/abutment interface was similar to each other. 4) The fit of the implant/abutment interface was usually good in the case of Friadent, Astra and Paragon system. The case of Astra system with the inclined contacting surface had the most Intimate contact among them. 5) Amount of intimate contact in the abutment screw thread to the mating fixture was larger in assembly with two-piece type which is separated screw from abutment such as Friadent, Astra and Paragon system than in that with one-piece type which is not seperated screw from abutment such as ITI, 3I and Avana system. 6) Amount of contact in the screw and the screw seat of abutment was larger in assembly of Friadent system than in asembly of Astra system of Paragon system. Conclusion: Although a little variation in machining accuracy and consistency was noted in the samples, important features of all internal connection systems were the deep, internal implant-abutment connections which provides intimate contact with the implant walls to resist micro-movement, resulting in a strong stable interface. From the results of this study, further research of the stress distribution according to the design of internal connection system will be required.

  • A literature review and survey were conducted regarding the silhouette changes in bell bottom pants and the overall visual evaluation in accordance with the changes. The survey was disseminated from December 2015 to January 2016 to 245 women in their 20s living in Busan. The variables used for the silhouette changes in bell bottom pants were the volume of flare and the flare's starting point, and 20 pairs of terms were selected for visual evaluation. The results of the study are as follows: 1. Visual evaluations according to the volume of flare in bell bottoms indicated that females in their 20s appraised pants with a flare volume of 54 cm close to a straight silhouette and flare volume of 62 cm (recognized clearly as characteristic of bell bottom pants) to be more attractive and sophisticated than pants with flare volumes of 70 cm and 78 cm. 2.Visual evaluations according to the starting point of the flare in bell bottom pants showed that women appraised their legs as looking thinner when the flare started near the thighs. In a vertical visual evaluation, women appraised that their legs looked longer when the flare started near the knees and pants fit tightly around them. 3.The analysis of silhouette factors affecting the visual evaluation of bell bottom pants indicated that the volume of flare has more effect visually than the starting point of the flare.

  • 원산지 관련 연구는 오랫동안 마케팅과 국제경영 분야에서 연구되어 왔다. 최근 원산지 관련 연구는 급속도로 글로벌화 되어 가는 기업환경을 반영하여 원산지 효과의 존재를 입증 및 분석하고자 하는 연구흐름과 원산지 효과의 발생과정을 설명하고자 하는 연구흐름으로 분화 및 발전해왔다. 본 연구는 최근 단순한 원가절감 차원을 넘어서 브랜드 자체와 브랜드원산지의 경쟁력을 제고시키는 전략적 수단으로 활용되고 있는 제조원산지의 선택과 관련된 기업 활동의 효과를 설명하고자 하였다. 이를 위해 제조원산지와 브랜드원산지를 긍정조합 및 부정조합으로 구분하여 원산지효과를 검증하였으며, 이 과정에서 소비자의 동기성향(조절초점)이 갖는 조절효과를 살펴보았다. 연구 결과 긍정적인 원산지의 조합(예컨대, 일본에서 생산된 프랑스 브랜드 오디오)의 경우가 부정적인 조합(예컨대, 중국에서 생산된 독일 브랜드 의류)의 경우보다 호의적인 반응을 유발함으로써 제조국 원산지효과가 있음이 확인 되었다. 또한 개인의 동기성향이 제품에 대한 메시지의 내용과 일치할 때 제품에 대한 평가가 좋아지는 조절적 적합성(regulatory fit) 효과가 존재한다는 것도 확인 되었다. 끝으로 동기성향의 조절효과를 보았을 때, 긍정적인 원산지 조합에서는 개인의 동기성향에 따라 제품평가가 달라져 조절효과를 입증할 수 있었으나, 부정적인 원산지 조합에서는 동기성향의 조절효과가 태도 부분에서만 부분 지지되고 품질지각과 구매의도 부분에서는 지지되지 않아서 동기성향의 조절효과가 존재한다는 점을 부분적으로만 확인할 수 있었다. 연구결과를 토대로 기업이 제조원산지를 결정할 때 고려할 요소와 이미 제조원산지가 결정된 상황에서 보다 효과적인 마케팅 전략을 수립하기 위한 시사점을 제시하였다.

  • The shock absorber is a part having a direct influence on the ride comfort, stability and dynamic load prediction of a vehicle. Thus, a rationally modeled shock absorber should be required in the dynamic analysis of vehicles. This thesis presents a modified model, based on Worden's hyperbolic tangent function, in order to fit experimental data on the velocity-damping force of a shock absorber. The hyperbolic tangent function correctly indicates the characteristics of a shock absorber, and has the advantage of containing physical causality. To evaluate the method, comparative evaluations of the linear model, the 5th polynomial model and Worden's model were carried out. The function presented in this paper is not only simple but also makes it possible to estimate the function coefficients easily and visually. In addition, it has the advantage of containing physical causality. Lastly, it effectively models the damping force of a shock absorber.
