The mesencephalic trigeminal nucleus (Mes V) contains cell bodies of primary afferent sensory neurons that relay proprioceptive information from the periodontium and masticatory muscles and function as typical sensory neurons or potentially as integrative interneurons. In the present study, we studied these two potential functions using combined experimental approaches of retrograde labeling and whole cell patch clamp recording. Mes V neurons that presumably originate from periodontal nerve fibers in subsets of Mes V nucleus were identified by retrograde labeling with a fluorescent dye, DiI, which was applied onto inferior alveolar nerve. These cells were elliptical perikarya shaped cells about 40 μm in diameter. In these neurons, we measured high voltage-activated calcium channel (HVACC) currents. GABA_(B) agonist, baclofen, inhibited calcium currents, and the HVACC currents inhibition by baclofen was voltage-dependent, exhibited prepulse facilitation, indicating that it was mediated by G_(i)/G_(o) protein. Taken together, our results demonstrate that Mes V neurons not only have cell bodies originating from periodontium, but also receive synaptic inputs including GABAergic neurons suggesting that Mes V neurons function as both primary sensory neurons and integrative interneurons.

Choi, Chel-Jong,Kang, Seung-Min,Hong, Hyo-Bong,Lee, Soo-Hyung,Kim, Jin-Gyu,Ahn, Kwang-Soon,Yoon, Jong-Won The Japan Institute of Metals 2010 MATERIALS TRANSACTIONS Vol.51 No.4

<P>We fabricated metal-oxide-semiconductor (MOS) devices with a high-k Er-silicate gate dielectric, and demonstrated their electrical performance. The increase in the rapid thermal annealing (RTA) temperature leads to a reduction of the equivalent oxide thickness (EOT), which is attributed in par to the thickness evolution of Er-silicate film and to the chemical bonding change from an Si-rich to an Er-rich silicate. The <I>in-situ</I> investigation of the interfacial reaction between the Er and SiO<SUB>2</SUB> film using a high-voltage electron microscopy (HVEM) revealed a linear relationship between the squared thickness of Er-silicate layer and <I>in-situ</I> annealing time, indicating that the Er-silicate growth is a diffusion-controlled process. The parabolic growth constants of the Er-silicate film were calculated to be 2.3×10<SUP>−16</SUP> and 9.3×10<SUP>−16</SUP> cm<SUP>2</SUP>/s for <I>in-situ</I> annealing temperatures of 350 and 450°C, respectively.</P>

Recently, as the technology of utilization for the ocean space is being advanced, floating structures are asked for being more and more huge-scale. A Very large floating structure(VLFS) is considered as a flexible structure, because of a quite large length-to-breadth ratio and its geometrical flexibility. The main object of this study is to develop an accurate and convenient method on the hydroelastic response analysis of very large offshore structures on the real sea states. The numerical approach for the hydorelastic responses is based on the combination of the three dimensional source distribution methods, the dynamic response analysis method and the spectral analysis method. A model is considered as many rigid bodies connected elastic beam elements. The calculated results show good agreement with the experimental and calculated ones by Ohta.

전효진 ( Hyo Jin Jeon ),김이연 ( Yi Yeon Kim ),주병철 ( Byeong Chel Ju ) 한국관광산업학회 2015 Tourism Research Vol.40 No.3

본 연구는 커피 전문점 브랜드 PPL광고의 수용태도가 커피브랜드 인지도에 어떠한 영향을 미치는지, 그리고 관여도의 조절효과 여부를 알아보고자 하였다. 최근 커피시장이 커지고 소비자의 수요가 늘어나면서 커피브랜드 광고가 다양해지면서 특히 TV드라마 속 커피브랜드 PPL이 빠르게 증가하고 있는 실정이다. 커피관련 기업들은 자사의 상품이나 브랜드를 간접적으로 영화나 TV드라마를 통해 노출함으로써 브랜드 인지도를 상승시킬 홍보수단으로 PPL을 이용하고 있다. 이에 본 연구에서는 커피 전문점 브랜드 PPL광고의 수용태도가 커피브랜드 인지도에 미치는 영향, 그리고 수용태도와 브랜드 인지도 사이에서 관여도의 조절효과를 통해, 세 변수간의 영향관계를 알아보고자 한다. 본 연구의 결과를 요악하면 다음과 같다. 커피 전문점 브랜드 PPL광고의 3가지 수용태도인 인지적 태도, 감정적 태도, 행동적 태도 중, 행동적 태도만이 브랜드 인지도에 유의한 영향을 미치는 것으로 나타났다. 즉, PPL광고를 받아들이는 인지과정, 주관에 의한 평가를 내리는 감정과정까지 진행되었다고 해도 행동과정까지 이어지지 않으면 브랜드 인지도 상승을 기대하기 어렵다고 해석할 수 있다. 관여도에 관한 측정은 소비자 개인의 특성요인, 제품 특성요인, 상황 특성요인 등 3가지 관여도 중 소비자 개인의 특성요인을 바탕으로 진행하였으며, 세 가지 수용태도 중 감정적 태도에만 조절작용을 하는 것으로 나타났다. 이상의 연구 결과를 토대로 하여 이끌어 낼 수 있는 시사점으로는 먼저 커피전문점의 PPL광고를 제작 시, 제품보다는 간판이나 로고, 브랜드 슬로건 등이 부각되도록 해야 광고효과가 극대화 된다는 점을 들 수 있다. 또한 커피 전문점 브랜드에서 소비자의 수용태도를 바탕으로 브랜드 인지도를 상승시키기 위해서는 커피 전문점 브랜드의 PPL광고를 통하여 받아들이는 수용태도 중 행동적 태도가 필요하며, 관여도는 감정적 태도에만 조절작용을 한다는 것을 알 수 있다. 브랜드 인지도 특히 행동적 태도를 이끌어내기 위해 소비자가 PPL광고와 관련지어 직접 참여할 수 있는 체험 마케팅 등을 적극 활용할 필요가 있다고 볼 수 있다. This study aims to examine how individuals`` maternal attitude toward PPL(Product Placement) affects their coffee brand awareness. Recently, companies attempt to improve familiarity of their brand and products to the consumers by exposing the products indirectly in films or TV shows. In last few decades, as the customer needs grow up for the coffee market, coffee brand commercials have been increased. Especially, PPLs in TV series have been grown up dramatically. Therefore, this study was designed to study the relationship between individuals`` maternal attitude toward, namely emotional attitude, recognition attitude, and behavioral attitude, and coffee brand awareness. Also, the moderating effect of involvement in the relationship was also examined. The results are as follows. First, the results show that among three types of maternal attitude, behavioral attitude only had significant effect on brand awareness while other did not have significant effect. This implies that brand awareness will not be increased unless customers arrive in the behavioral stage. Second, the results show that involvement only moderated the relationship between emotional attitude and brand awareness. Based on the study result, the conclusion is that increasing the positive reputation or the brand awareness of coffee brand by brand PPL is essential business activity to arouse customer’s purchase needs. In particular, among three types of maternal attitude, behavioral attitude should be more highlighted to build a good brand awareness.

Hyung-Chel Cho,Hyo-Lyun Ro 한국융합학회 2021 한국융합학회논문지 Vol.12 No.2

본 연구는 시각적인 장애를 호소하는 ADHD로 진단받은 아동의 유형별 시각 기능의 특징을 확인하고자 하였 다. 연구 대상자는 ADHD로 진단받은 아동 49명으로 시각기능이 정상범위에서 벗어난 경우이다. Korean-ADHD Rating Scale을 이용하여 ADHD 유형을 알아보았고 시각기능 검사를 통해 시각 기능의 문제를 알아보았다. 시각의 문제를 가지고 있는 ADHD 아동들은 부주의 유형(69.4%)이 가장 많았으며 시력은 좋지만 시각 기능 문제가 드러난 경우도 50% 정도 되었다. 주의력결핍 유형에서 근시 관련 시각장애, 과잉활동형 유형에서 난시 관련된 시각장애가 높 게 나타났다. 버전스 기능 장애에서는 폭주부족이 가장 많았으며 유형별 차이는 나타나지 않았다. ADHD 아동의 유형 별 시각장애의 특성은 차이가 나타나므로 시각 기능 장애의 검사와 선별을 통해 아동의 문제행동에 접근하는 것이 필요하다. The objective of this study is to identify the visual function impairment of children with each type of attention deficit hyperactivity disorder(ADHD). The subjects of this study were 49 children diagnosed with ADHD with visual function out of the normal range. The type of ADHD was investigated using the Korean-ADHD Rating Scale and visual function test. The attention deficit type(69.4%) of ADHD was the most common type among children with ADHD with vision problems. Although their overall naked-eye visual acuity was good, about 50% of the subjects showed problems with visual function. For those with the attention deficit type of ADHD, the myopia-related refractive error was high. For those with the hyperactivity type of ADHD, the astigmatism-related refractive error was higher. For those with vergence function disorder, convergence insufficiency was the most common. As there were differences in the visual impairment characteristics of children with different types of ADHD, it is necessary to approach a child's problem behavior through examination and screening for visual function disorders.

This study compared and verified the food service companies and the manufacturing industry using SGR model proposed by Higgins (1997, 1981). According to the analysis,, first, they were maintaining AG and IRG with no average differences and yet, as for TG, the increment value duty of tangible assets, the food service companies came up with 12.1% while the manufacturing industry presented 7.45%, and that was a proof for the former `s having a 1.6-times greater real investment. Second, according to the analysis on IGR, the food service companies would have 7.08% of the maximum annual growth without any fund support from outside while the manufacturing industry will be able to grow up to 4.76% every year. Third, the analysis on SGR confirmed that the food service companies had 1.3-times higher one than the manufacturing industry. Fourth, the ANOVA analysis on SGR and the potential growth rate reported that the food service companies had a 3.45-times higher one comparing to this 2.6-times higher difference of the manufacturing industry, and they were observed to be higher than the potential growth rate. In the light of that, the study confirmed that the food service companies had more confident growth potential. In conclusion, comparing to the manufacturing industry, the stable financial structure and the efficient sales activities will be a foundation for the survival and the growth of the food service companies.

빛의 특성을 적용한 치유(Healing)스파(Spa)공간계획에 관한 연구

이지효(Lee, Ji-Hyo),강철희(Kang, Chel-Hee) 한국실내디자인학회 2018 한국실내디자인학회 학술대회논문집 Vol.20 No.1

Spas have become increasingly popular and popularized as they have been attracting attention in order to maintain modern people"s means of healing and improving their quality of life. However, the existing spa spaces are in the form of program concentration in a simple form. The purpose of this study is to introduce the new healing environment elements of the spa space to meet the needs of the modern society and to approach the emotional factors to maximize the healing effects. The surface and psychological aspects were derived to analyze the effect on space. Light and space are interconnected. Therefore, light is a basic and important element in spa space implementation. In this study, it is found that various characteristics are generated by the environmental factors in the indoor space based on the properties of light through analysis of the characteristics of light. Light changes the interior by direction, intensity, color, etc., and changes the texture, atmosphere and personality to maximize positive effects on mind and body. Light makes the relationship between space and man more closely, and through this, it provides an environment of healing space in which human mind, body and physical environment can be fused together. This study suggests the diversity of healing space that healing effect can be applied by applying the characteristics of light to spa space. Based on this research, it seems that the design of the healing environment of the new spa space which can stimulate emotion in the future should be widely done.
