이 연구는 컴퓨터 작업시 의자 등받이 위치가 근육활성도에 미치는 영향을 알아보기 위해 36명의 근골격에 문제가 없는 성인 남녀가 참가하였으며 대상자들은 등받이가 뒤에 있는 의자와 등받이가 없는 의자, 등받이가 앞에 있는 우리들 의자를 무작위로 배정하고 동일한 컴퓨터 작업을 실시하게 하였다. 실험 중, 표면근전도기를 사용하여 의자에 따른 위등세모근, 머리널판근 그리고 척주세움근의 근활성도 변화를 측정하였다. 이 연구의 결과를 종합해보면 등받이가 앞에 있는 의자는 허리 근육의 부담을 줄이지만 목근육에 부담이 늘어나고 등받이가 뒤에 있는 의자와 없는 의자는 허리근육에는 다소 무리가 가지만 목근육에는 부담이 덜하다는 것을 알 수 있었다. 이러한 결과로 환자의 증상에 다라 컴퓨터 작업을 하는 동안 의자 등받이의 위치를 조절하여 치료에 도움이 될 수 있다고 생각되어진다. Objective : In this study, we checked and observed people's change of body muscle and muscle activity who do computer work on different chairs. We set three kind of chairs which one is a stool and another one is the back is fixed, and the other one is the back is fixed in front of chair. Subject : Accounting for 36 health men and women, we divided these people to 3 groups and put them on the three cases(position 1, position 2, position 3). We measured muscle activity of upper trapezius, Splenius Cervics, Erector Spinae from the groups by using surface electromyogram system. Methods : The standard of the electromyogram was 'reference voluntary contraction', and we carried out 'one way anova' to compare muscle activity of three groups. Results : In position 1, reference voluntary contraction of upper trapezius muscle activity was 123.2821%, Splenius Cervics was 141.7526%, and Erector Spinae was 254.5233%. In position 2, reference voluntary contraction of upper trapezius muscle activity was 132.9395%, Splenius Cervics was 141.7526%, and Erector Spinae was 246.6540%. In position 3, reference voluntary contraction of upper trapezius muscle activity was 190.6487%, Splenius Cervics was 270.2332%, and Erector Spinae was 182.1021%. Both upper trapezius and Splenius Cervics muscle activity of position 3 group was higher than the others groups. In position 1 group, Erector Spinae muscle activity was hight than the other groups. And either was position 2 group's(p<0.05). Conclusion : Therefore the chair which is the back is fixed in front is more comfortable for waist muscle but it's not good for neck. And the other chairs are better in waist muscle but not in neck muscle. So far, when we do a computer work, it's prefer to sit on the group 1&2's chairs to reduce neck muscle's stress and sit on group 3's chair to reduce waist muscle's stress.

최명애,신기수,이은주,안경주 대한기초간호자연과학회 2001 Journal of korean biological nursing science Vol.3 No.1

The purpose of this study was to determine the effect of DHEA with dexamethasone on body weight and wet weight and relative weight of atrophied hindlimb muscles induced by dexamethasone treatment. 200~225g Wistar rats were divided into control(C), dexamethasone(D), dexamethasone and DHEA(DDH) groups. Dexamethasone was injected daily at a dose of 5mg/kg. DHEA was administered daily at a dose of 5mg/kg by oral ingestion during 7days. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Body weight and muscle weight of plantaris and gastrocnemius of dexamethasone group decreased significantly compared with that of control group. Muscle weight of plantaris of DDH group increased significantly compared with dexamethasone group. Body weight of DDH group decreased significantly compared to control group, but relative weight of plantaris and gastrocnemius of DDH group increased significantly compared to control group. Based on these results, it can be suggested that DHEA administration during dexamethasone treatment can increase weight of atrophied plantaris muscle induced by dexamethasone treatment.

본 논문은 발달장애유아 언어행동발달 컨텐츠 개발에 요구되는 기초연구로써 연구의 이론적 바탕을 확립하고자 하였다. 연구에 사용된 방법은 문헌조사 방법 및 현장 인터뷰기법을 병행하였다. 본 연구의 주된 목적은 크게 3가지로 구분된다. 첫째, 발달장애유아의 가정 내 교육 욕구를 분석하고자 하였다. 둘째, 발달장애유아의 언어발달 양상을 검토하고자 하였다. 세 번째 목적은 유아의 언어행동발달 컨텐츠 구성의 주요 지침을 설정하고자 하였다. 이상의 연구목적에 따른 연구결과를 요약하면 다음 몇 가지로 제시된다. 1.가정 내 부모-유아간 관계형성이 우선 고려 되어야하고, 이에 따른 상호작용은 발달적 애착형성이 가능한 방향으로 정립되어야한다. 2.발달장애유아의 언어행동발달양상을 검토한 결과에 따르면, Piaget는 언어행동발달에 있어 감각운동기적 환경탐색 기능을 강조하고 있고, 이는 현재까지 중요한 유아 발달의 기저로 정착되었다. 따라서, 발달장애유아의 언어행동발달을 위한 컨텐츠 개발 내용에 있어서도 이러한 기저에 충실함이 합리적이다. 3.발달장애유아들에게는 언어행동 양상의 갈래가 크게 운동장애 및 감각결함으로 나누어질 수 있으므로, 이 두 가지 갈래의 각기 다른 특성이 컨텐츠 구성에서 충분히 고려되어야한다. 4.자폐성과 같은 중증 전반적 발달장애 유아를 위한 언어행동발달 컨텐츠 구성에서 특히 고려해야 할 두 가지 요소는 모방행동기능과 반복단순훈련기능 향상으로 결론지을 수 있다. This article planed to establish the theoretical foundations of the research as a basic study needed for developing the contents of verbal(language) behavior development for the infants with developmental disabilities. The methods used in the study was previous literature researches and interviews with subjects. The purposes of the study were divided into three parts. First, it was to analyze the educational needs of the infants with developmental disabilities in home settings. Second, it was to review and discover the language patterns of the infants with developmental disabilities. The third purpose was to devise the major guidelines of their language development's contents. The results of the study were described as the followings. 1.The relationships between the infants with developmental disabilities and their parents and their interactions should move to build the developmental attachments between them. 2.According to the literature findings of their language development patterns, Piaget concentrated on the functions of sensory motor environmental exploring in the language behavior development. The functions have been settled down into the important foundation for the infants' development. Thus, it was resonable that the content's development of the language behaviors for the infants with developmental disabilities should based on the function addressed by Piaget. 3.The language behaviors' patterns of the infants with developmental disabilities generally were classified into motor disabilities and sensory defect(deficiency). Therefore, the two factors should be considered for the constructions of the contents. 4.Constructing the contents of the language behavior developments for the infants with severely pervasive developmental disabilities such as autism, the improvements of two functions, imitative behavior and repetitive simple training should be considered.

Eun Gyeong Shin,Ji Min Ha,Soobeen Parka 한국색채학회 2017 AIC 2017 Jeju Vol.2017 No.10

This study focused on subjects` emotional responses to color combinations. Subjects in their 20s participated in the experiment. Four living room images were constructed using a computer graphic program. The rooms were two analogous color combinations (R-YR, PB-B), and two complementary color combinations of warm and cool colors (R-BG, PB-Y) using the IRI 120 Hue & Tones system. The images were presented through a 23-inch LED monitor. Subjects responded to the SD scales, which included Valence and Arousal responses. The major findings are as follows. 1) When comparing each of the color images by SD scale responses, the subjects felt the warmest, lightest, softest, and brightest when viewing the R-YR image. The subjects felt the heaviest, hardest, and most disliked when viewing the PB-Y image. They also felt the dullest when viewing the R-BG image. 2) On the valence scale, the subjects felt the most pleasant when viewing the PB-B image and the most unpleasant when viewing the PB-Y image. On the arousal scale, the responses of the subjects showed no significant differences when compared among all of the colored images.

The goals of healthcare design based on the human rights to manage physically, psychologically, and emotionally healthy life. The healthcare design, however, have been criticized not to reflect their primary users, patients` and families` needs, under the management strategy centered by the functional efficiency. The study focused on the patients` room design on the users` perspective. The design criteria for the patients` room in Japan, Germany, Australia, U.S. and Korea were examined and compared. The subjects of analysis are the floor plans of general hospital recently planned and built in Korea and Japan and the standard floor plan models proposed by prior studies in Korea and AusHFG in Australia. Results and conclusions are as follows: (1) the patients room has developed as a place where the users manage their living during inpatient period and has become a private room. (2) The guidelines for patients` room size in Korea and Japan are not enough considering the users` diverse activities compare those in U.S. and Australia. (3) The guidelines of Korea should be reconsidered for the users` comfortable lives. It must include the specific criteria of the enough space between beds, the storages, and other assistant tools and facilities. (4) The desirable types of patients` rooms by the numbers of users in Korea are proposed as a one-bed room type and a four-bed room type.

한식의 스토리텔링이 고객만족 및 고객행동에 미치는 영향에 있어 관여도의 조절효과

정경은 ( Gyeong Eun Chung ),신은경 ( Eun Kyeong Shin ) 한국관광산업학회 2014 Tourism Research Vol.39 No.2

이야기를 전달한다는 것, 이른바 스토리텔링 기법이 최근 마케팅을 중심으로 여러 매체의 주목을 받고 있다. 최근 한식재단은 비빔밥과 불고기를 비롯한 290여 종류의 한식에 대해 흥미롭고 다양한 ``한식메뉴 스토리텔링``을 제시했다. 스토리텔링은 고객 만족 및 고객행동의 과정의 여러 단계에서 활용 가능하지만, 본 연구에서는 한식에서의 스토리텔링의 활용, 특히 관여도에 따른 고객만족의 효과 및 고객의 행동인 재방문의도 및 구전의도 대해 살펴보고자 한다. 따라서 한식의 스토리텔링이 고객만족과 그 만족이 고객행동에 어떤 영향을 미치는지 알아보고, 외식산업에서의 스토리텔링에 대한 바람직한 활용방안을 제시하고자 한다. 한식 스토리텔링에 나타난 변수들은 흥미성, 고유성, 교육성, 일관성, 묘사성으로 꼽았고, 이러한 선행 요인들이 고객만족 및 고객행동에 대한 영향력에 대한 관계를 제시하였다. 실증 분석으로 나타난 이론적인 모형에서 각각의 변수들이 고객만족과 고객행동에 영향을 주고 있으며, 이들 요인들과 고객만족사이에서 관여도가 조절효과를 보이고 있는 것으로 나타나 일반적인 수준으로써 구성개념과 모형에 적합하다고 분석되었다. 본 연구의 시사점은 이론적 측면에서 선행요인인 흥미성, 고유성, 교육성, 일관성, 묘사성을 제시하였고 이를 정립하였다. 또한 실용적 측면에서는 스토리텔링을 통하여 한식의 활성화를 추구할 수 있으며, 한식을 세계화 시킬 수 있는 상품을 만들 수 있을 것이다. Storytelling has attracted increasing media attention as it has increasingly been a significant part of marketing strategies. Therefore, focusing on Korean food users, this study examines causal relationships between storytelling, customer satisfaction, and customer behavior and moderating effect of involvement on the relationship between storytelling and customer satisfaction. The findings of the study is as followed: First, four dimensions of stroytelling, namely Interest, Education, Consistency, and Delineation, positively influences customer satisfaction, while one dimension, Uniqueness, does not significantly affect customer satisfaction. Second, customer satisfaction positively influences two dimensions of customer behavior, such as revisit intentions and Word of Mouth. Third, involvement has moderating effect on the relationships between four dimensions of storytelling (Uniqueness, Education, Consistency, Delineation) and customer satisfaction, while it does not significantly moderates the relationship between Interest and customer satisfaction. These results indicate that storytelling plays an important role in increasing customer satisfaction and positive customer behaviors. Therefore, it is suggested that to globally promote Korean food, storytelling can be a key strategy.

This study proposes the structural model of inpatient"s satisfaction with their room. Relationship among patients" privacy, patients" stress, and patients" satisfaction were evaluated and were discussed. Survey research followed the literature review, in which the subjects answered questions of the 12 items for the patients" privacy requirements, 10 items selected from the HSRS, and an item of patients" satisfaction. A total of 120 copies were analyzed through the statistical process using the SPSS Win Program 20.0 and SEM by the AMOS 20.0. Results and conclusions are as follows: (1) the inpatients" privacy requirements was subdivided into "the reserve factor", "the territoriality factor", and "the solitude factor". (2) The inpatients" stress level was subdivided into "the relationship factor", "the unfamiliarity factor", and "the control factor". (3) The model of relationship among the subjects" privacy requirements, stress level and their satisfaction with the patients" room showed that the subjects’ stress level affected their satisfaction with the patients’ room directly and the subjects’ privacy requirements gave an direct and indirect effect on their’ stress level and an indirect effect on their satisfaction with patients’ room.

Flavonoids Identified from Korean <i>Scutellaria baicalensis</i> Georgi Inhibit Inflammatory Signaling by Suppressing Activation of NF- <i><i>κ</i></i> B and MAPK in RAW 264.7 Cells

Hong, Gyeong-Eun,Kim, Jin-A.,Nagappan, Arulkumar,Yumnam, Silvia,Lee, Ho-Jeong,Kim, Eun-Hee,Lee, Won-Sup,Shin, Sung-Chul,Park, Hyeon-Soo,Kim, Gon-Sup Hindawi Publishing Corporation 2013 Evidence-based Complementary and Alternative Medic Vol.2013 No.-

<P><I>Scutellaria baicalensis</I> Georgi has been used as traditional medicine for treating inflammatory diseases, hepatitis, tumors, and diarrhea in Asia. Hence, we investigated the anti-inflammatory effect and determined the molecular mechanism of action of flavonoids isolated from Korean <I>S. baicalensis</I> G. in lipopolysaccharide- (LPS-) stimulated RAW 264.7 macrophages. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed to examine cytotoxicity of the flavonoids at various concentrations of 10, 40, 70, and 100 <I>µ</I>g/mL. No cytotoxicity was observed in RAW 264.7 cells at these concentrations. Furthermore, the flavonoids decreased production of inflammatory mediators such as inducible nitric oxide synthase, cyclooxygenase-2, interleukin-6, and tumor necrosis factor-alpha and inhibited phosphorylation of nuclear factor-kappa B (NF-<I><I>κ</I></I>B) and mitogen-activated protein kinases (MAPKs) in LPS-induced RAW 264.7 cells. Moreover, to identify the differentially expressed proteins in RAW 264.7 cells of the control, LPS-treated, and flavonoid-treated groups, two-dimensional gel electrophoresis and mass spectrometry were conducted. The identified proteins were involved in the inflammatory response and included PRKA anchor protein and heat shock protein 70 kD. These findings suggest that the flavonoids isolated from <I>S. baicalensis</I> G. might have anti-inflammatory effects that regulate the expression of inflammatory mediators by inhibiting the NF-<I><I>κ</I></I>B signaling pathway via the MAPK signaling pathway in RAW 264.7 cells.</P>
