Lee,Jee Eun,Lee,Sang Suk 한국상품학회 2021 商品學硏究 Vol.39 No.5

The purpose of this study is to examine the relationship between the perceived quality and revisit intention of the use of SNS, and then verifies the mediating role of the SNS channel between them. To achieve the purpose of this study, a total of 350 questionnaires were distributed at various coffee concept shops in the Korean metropolitan area (Seoul / Gyeonggi), including global / domestic brands. After removing the response with the missing information, the sample was 320 (91.4%). A structural equation model using AMOS 20.0 tested the hypotheses. Hypotheses are tested and confirmed by analyzing Korean coffee concept shops and the results have shown that information sharing and interaction of SNS play an important role in understanding perceived quality and revisit intention. Moreover, this study empirically verifies that when customers recognize the quality of products, including service and experience quality, they use SNS channels to visit the coffee shop again. The result of the study supported that information sharing and interactivity of SNS played critical roles in understanding perceived qualities and revisit intention. We empirically provide evidence that product quality of perceived qualities has direct positive in fluence on SNS channel and revisit intention. In addition, information sharing and interactivity of SNS channel has indirect significant impacts on intent to revisit. The result of research has shown that product quality had crucial impact on SNSs channel than service or experience quality. The study also shows that increasing the quality level of a product has a positive relationship with social media channels, which in turn can have a positive effect on information sharing and interactions. This study empirically examines that when customers perceive a product quality including service and experience quality, it induces them to use SNS channel, which eventually make them to revisit the store.

The objectives of the current study were to evaluate the therapeutic effect of dioctahedral smectite (smectite) against calf diarrhea caused by pathogenic E. coli and/or Salmonella typhimurium. In this study, 20 calves (aged 2~3 months) with diarrhea were used for evaluation of the efficacy of smectite on calf diarrhea with 20% smectite suspension in PBS. Calves received 10 ml smectite suspension three times per day after feeding, and fecal samples were collected at the gate of treatment and on the first, second, third, fourth, and fifth day after administration. On the fifth day after treatment with smectite suspension, the diarrhea index showed a significant decrease in the treated group, compared to the control group (P<0.001). The number of pathogenic E. coli in feces of the treated group was significantly decreased, compared to each control group from the second day after treatment (P<0.001), and that of Salmonella typhimurium was significantly decreased from the first day after treatment (P<0.05). According to the results of the current study, 20% smectite suspension had a therapeutic effect on diarrhea caused by E. coli and/or Salmonella in calves.

Y. S. LEE, S. D. EUN. The Movement of Foot and the Shift of Ground Reaction Force in Batters according to the Ball Speed Increase. Korean Journal of Sport Biomechanics, Vol. 14, No3, pp. 191-202, 2004. The batting performance in baseball is a repetitive movement. In order to make the stabilization of posture and the efficient shift of body weight, both the range of stance and stride are important. The previous studies explained that the consistent stride which included the amount of time, stance, and direction were needed. However, the batting performance is frequently changed according to the several speed of ball. Therefore, this study was to analyze the reaction time, the range of stance, the change of stride, and the change of GRF during the batting movement in three kinds of ball speed (120km/h, 130km/h, & 140km/h). Seven elite players are participated in this study. 1. The reaction time of the stride phase was short whereas the time of the swing phase was long according to the increasing ball speed. 2. The range of the stance was wide and the mediolateral direction of the stride was decreased according to the increasing ball speed. 3. In the three kinds of ball speed, the change of body weight was transferred to the center, the rear foot, and the front foot directions. The ball speed of 130km/h showed the high frequency of the suitable batting. At this ball speed, the movement of the body weight was shifted smoothly and the value of the Ground Reaction Force was large enough.

노인 낮병원의 심리사회적 치료 프로그램이 노인의 신경인지기능과 우울 증상에 미치는 효과

유계준,송정은,오병훈,안석균,이홍식,오희철,구은형,황혜숙,이은철 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.5

노인에게 있어서 신경인지기능의 저하와 우울 증상은 가장 흔한 장애이며 신체적, 정신적인 면에 많은 영향을 미치고 있다. 또한 이러한 장애중 비임상군에서 심리사회적 치료개입의 효과가 보고되고 있다. 이러한 측면에서 지역사회에서 노인에게 제공되는 심리사회적 치료개입의 중요성이 높아지고 있다. 이전의 연구에서는 대상이 특정 집단이거나, 비교군이 없거나, 치료효과에 대한 추적 관찰이 이루어지지 않는 등의 제한점이 있었으며, 현재 국내의 노인 낮병원은 소수에 불과하고 이러한 낮병원의 치료효과에 대한 연구는 거의 없는 실정이다. 따라서 본 연구는 지역사회 정신보건센터에서 운영하는 노인 낮병원에 참가하는 노인들을 대상으로 낮병원의 심리사회적 프로그램이 노인들의 신경인지기능과 우울 증상에 미치는 효과와 이에 대한 유지 효과의 유무를 알아보고자 하였다. 경기도 광주군 정신보건센터의 노인 낮병원에 참여한 노인을 치료군으로, 치료를 거부하거나 치료 중 탈락한 노인을 비교군으로 하여 10주간의 낮병원 치료전후와 치료종결 후 10주에 신경인지기능은 한국형 간이 정신상태검사(이하 MMSE-K)로, 우울 증상은 단축형노인우울척도(이하 SGDS)로 평가하여 두 군을 비교하였고 치료군의 치료 직후와 치료종결 후 10주를 비교하였다. 연구결과 노인 낮병원의 심리사회적 치료가 시간에 따른 SGDS점수 변화에 통계학적으로 유의한 영향을 미쳤으며, MMSE-K점수 변화에는 통계학적으로 유의한 영향을 미치지 않았다. 또한 10주 추시가 가능했던 치료군 중 약 43%가 10주 후 SGDS가 증가하여 호전되었던 우울증상의 악화를 보였다. 본 연구 결과 노인 낮병원의 심리사회적 치료 프로그램 개입은 노인에게 있어서 우울 증상을 호전시키며 신경인지 기능에는 직접적인 영향을 미치지 않는 것을 알 수 있었다. 또한 상당수에서 심리사회적 치료 개입으로 인한 우울 증상의 호전이 유지되지 않음을 알 수 있었다. 이는 노인우울증상의 치료에 낮병원의 심리사회적 치료 프로그램이 효과적일 수 있음과 치료 후 이를 유지하기 위한 부가적인 치료개입의 필요성을 시사한다. Cognitive impairment and depression are the most common symptoms affecting the elderly on physical and mental states. Studies have shown that these symptoms in mild cases are improved by psychosocial intervention, emphasizing the importance of therapeutic intervention provided in the community. The purpose of this study was to investigate whether the psychosocial program at a geriatric day care service has any therapeutic effect on the cognitive function and depressive symptoms in the elderly and whether such effect can be maintained. The experimental group was composed of 37 elderly patients attending the day care service at the mental health center located in Kwangju county, Kyonggi province. The control group was composed of 22 elderly patients who either refused intervention or who dropped out of the program. Cognitive function was assessed with the Korean version of the Mini-Mental State Exam(MMSE-K), and depressive symptoms were assessed with the Short-form Geriatric Depression Scale(SGDS). The experimental group and the control group were compared on the score of on each test, which was administered before and after the program and 10 weeks after discontinuation of program. In the experimental group, the scores acquired immediately after the program and at 10 weeks of follow-up were also compared. The results showed that psychosocial intervention at a geriatric day care service was significantly associated with the change in SGDS scores dependent on time but not significantly associated with the change in MMSE-K scores. In the experimental group whose follow-up assessment was possible, it was further shown that 43% of patients had increased SGDS scores 10 weeks after the program ended, indicating that depressive symptoms had worsened. This study suggests that psychosocial therapeutic intervention in the geriatric day care service improve depressive symptoms but not cognitive functions in the elderly. In addition, for a considerable percentage of subjects in the experimental group, the improvements in depressive symptoms were not sustained after the intervention was withdrawn. These findings proposes a need of strengthening therapeutic intervention to maintain such effect.

이은주,오창석 충북대학교 컴퓨터 정보통신 연구소 1997 컴퓨터정보통신연구 Vol.5 No.1

This paper presents an ATM based transport architecture for next-generation multimedia services in personal communication networks(PCN). Multimedia services via wireless networks are motivated by an anticipated demand for wireless extensions to future broadband networks. An ATM based wireless network concept is explored as an architectural viewpoint for supporting B-ISDN services. The proposed system uses a hierarchical ATM switching network for interconnection of PCN microcells, each of which is serviced by high-speed, shared access radio links based on ATM-compatible cell relay principles. Design issues related to the physical layer, media access control(MAC) layer and data link layer of the ATM-based radio link are discussed, and preliminary technical approaches are identified in each case. Also, this paper concludes with a brief view of related supporting scenario for a seamless wired plus wireless multimedia networking environment.

The application of recently developed rotary instruments to oral and maxillofacial surgical procedures has interrupted the healing process by affecting the temperature rise during drilling the bones. To evaluated the effects of healing process on the rabbit's calvarial defects, we have drilled the 6 holes on the calvarial bone resulting in three groups respectively according to 38, 300 and 20000 rpm, which divided into another two different groups operated under saline irrigation, and others not. Each specimen was sacrified at 3 days, 1, 2, 4, and 6 weeks post-operatively and routine fixation, Hematoxylin & Eosin stains and examined under light microscopic findings. The obtained results were as follows; 1. In each rpm, the healing processes of the saline irrigation groups were faster than those of no saline irrigation groups. 2. The lower the rpm of rotary instrument was, the faster the healing process. 3. In groups of using rotary instrument below 20000 rpm, there was appeared the good healing process that was operated under the low rpm with saline irrigation.

MLS를 이용한 접근 유도에 관한 연구

李貞碩,張殷永,金元厚,方孝昌 한국항공대학교 1991 論文集 Vol.29 No.-

MLS(Microwave Landing System)는 어떤 활주로 상황에서도 기종에 관계없이 계기착륙이 필요한 항법정보를 정확하고 신롸성있는 상태에서 넓은 운용범위를 갖게되는 시스템으로서 ILS보다 장비기술 및 운용면에서 우수한 것으로 입증되었으며, 공항의 장애물과 악지형의 영향에 따라 유도특성이 방해받더라도 시스템의 가용성에는 제한이 없도록한 특징이 있다. 본 논문에서는 기존의 ISL의 접근절차로서는 불가능했던 비표준 지형과 평행 활주로에서 MSL를 이용한 접근 유도시 활주로 중심선에 대한 접근 오차 한계를 계산하고 기준 활주로와 평행 활주로 각각에 대한 접근유도시 거리오차를 산출하여 MSL를 이용한 정밀 접근유도 상태를 검토하였다. 그 결과 MSL는 비표준 지형 및 평행 활주로에서도 5NM이내의 거리에서는 접근오차가 0.1%(0.16NM)이내를 유지하여 ICAO 기준을 만족함으로써 규정상의 접근유도가 가능함을 알수 있었다. The MLS was followed by definition of a signal-in-space having the accuracy, reliability and coverage to aeronautics needs for all type of aircraft at all runway suitable for terminal instrument procedures. MLS has been demonstrated to be superior to ILS from both technical and operational capabilities. Even at runway where ground terrain and airport obstacles prevent standard split-site installations, the availability of MLS will not be limited. In this thesis, the range error and limitted error bound of a computed centerline approach is derived and identified in order to solve the problems of percision approach guidence at non-standard sitin gand parallel runway. As the result, it is known that the MLS is able to approach guidence with 0.1%(0.16NM) limited range error at non-standard siting and parallel runway within 5NM.
