The Role of Multiple Mediating Effects of SNS Channel between Perceived Quality and Revisit Intention in Coffee Concept Shops

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.

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.

이산화탄소로부터 올레핀 합성을 위한 혼성 촉매와 Fischer-Tropsch 합성 촉매의 비교 연구

이성철,장재훈,서은철,강민철,정석진 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.1

이산화탄소로부터 메탄올을 경유하여 올레핀을 생산하는 연계 공정 대신, 이산화탄소로부터 올레핀을 직접 합성하는 일괄공정을 위하여 두 가지 촉매계를 시험하여 보았다. 즉, 메탄올 합성용 촉매와 메탄올 전환용(Methanol to Olefin process: MTO) 촉매를 혼합하여 구성된 혼성 촉매계와 종래의 Fischer-Tropsch 공정에서 사용되는 철 촉매계를 기반으로 하여 개선된 총매곌르 사용하여 보았다. 일괄 공정 중, 혼성촉매계에서는 Cu/ZnO/Al_2O_3와 Mg-La/ZSM-5로 구성된 혼성촉매가 가장 우수한 이산화탄소 전환 활성을 나타냈으나 구리에 기인한 중간세기 산점의 증대와 강산점의 소멸로 인하여 올레핀의 선택성은 미비하였다. 반면에 종래에 F-T 공정에 사용되는 철 촉매계의 경우 ZSM-5를 담체로 사용하고 특히 알칼리 금속인 K를 조촉매로 사용할 경우 CO_2흡착량을 증가시키게 되며 동시에 촉매 표면에 흡착된 Fe-C종의 결합 강도를 높여 줌으로 인하여 높은 이산화탄소 전환율과 올레핀 선택도를 확보할 수 있었다. One-step conversions of CO_2 into olefins were investigated over conventional Fischer-Tropsch synthesis(FTS) catalyst and the new hybrid catalysts. The hybird catalyst was consisted of methanol synthesis catalyst(Cu/ZnO/Al_2O_3, Cu/ZnO/ZrO_3) and methanol to olefin(MTO) catalyst(Mg-La/ZSM-5). The activity of hybrid catalytic system, which was mixed with Cu/ZnO/Al_2O_3(6:3:1 in weight ratio) and Mg-La/ZSM-5, was superior than others in terms of CO_2 conversion and total hydrocarbon yield, but olefin was not produced significantly. The reason was supposed to be caused by Cu-support interaction, which gives rise to the loss of strong Bro¨nsted acid site and consequently the medium strength acid site production. In contrary to hybrid system, the modified F-T catalytic system showed similar enhanced CO_2 conversion. However, it showed high selectivity to olefin. When ZSM-5 was used as a support for FE-K catalyst system, the selectivity of olefin was found to be increased. The addition of potassium promoters give rise to increase amount of CO_2 uptake on the surface, and the improvement of stability in adsorbed Fe-C species. Consequently, by carefully selecting the support and additives on modified F-T catalyst system, it was possible to obtain the high CO_2 hydrogenation activity as well as high olefin selectivity.
