  • COVID-19로 인해 비대면 문화 공연인 온라인 콘서트로 관람객에게 새로운 온라인 문화를 제공하고자 하는 노력이 다방면으로 점차 높아지고 있다. 그러나 현 시점의 온라인 콘서트는 오프라인 콘서트 중 다른 사람과의 상호작용을 온전히 살리지 못한다는 단점이 있다. 때문에 온라인 콘서트의 시청자에게 오프라인 콘서트와 같은 공통 경험을 제공하고자 한다. 본 연구는 관람객이 온라인 콘서트와 영화를 단독 및 그룹으로 시청하는 것으로 진행하였다. 연구 결과로 그룹으로 온라인 콘서트를 보는 것이 몰입감이 높아짐을 확인할 수 있었다. 향후 가상의 공동 시청 환경의 디자인 가이드로 활용될 수 있음을 확인하였다.

  • 본 연구는 고객이 부동산중개서비스 품질요인을 어떻게 평가하며, 중요한 품질요인으로 선호하는지에 관해 연구한 내용이다. 부동산중개서비스 품질요인으로 중개업자의 전문지식, 중개업자의 영업능력, 중개업자의 책임의식, 중개사무소의 입지, 프랜차이즈 가맹여부를 선정하였다. 연구결과를 살펴보면, 고객들은 다섯 가지 부동산중개서비스 품질요인 중 중개업자의 책임의식을 가장 중요한 품질요인으로 선호하는 것으로 분석되었으며, 그 다음으로 중개업자의 전문지식, 중개업자의 영업능력, 중개사무소의 입지, 프랜차이즈 가맹여부 순으로 분석되었다. 본 연구의 결과에서 보듯 중개업자는 중개업자로서의 책임의식과 전문지식을 향상시키는 데 노력해야 하며, 친절한 서비스와 적극적 중개행위로 영업능력을 향상시켜야 할 것이다. 중개사무소의 입지는 지속적인 홍보가 중요하다고 보여 지며, 프랜차이즈 가맹업소의 효율적인 활용을 위해서는 인터넷 정보망의 개선이 필요하다고 보여 진다. 본 논문은 부동산중개 계약을 경험한 고객들이 어떤 서비스를 필요로 하는지를 알아보기 위해 직접 면담을 통해 얻은 자료를 실증적으로 분석한 결과이다. 따라서 국토해양부의 업무관련부서와 중개협회에서는 본 자료를 참고하여 대책을 강구하는데 조금이나마 기여하였으면 한다. 아울러 중개업계와 중개업자들 스스로 경쟁에 치우쳐 한 치 앞만 보지 말고 중개업의 발전을 위해 지속적으로 노력하여야 할 것이다.

  • Objectives : The purpose of this study was to compare levels of parenting stress and efficacy in mothers of children suffering from attention-deficit hyperactivity disorder (ADHD) and internet addiction disorder (IAD), mothers of children with ADHD alone only, and those with normal children. Methods : Participants were composed of 25 mothers of children with ADHD and IAD, 35 mothers of children with ADHD alone, and 50 mothers of normal children. They completed the Parenting Stress Index (PSI) and Parenting Sense of Competence (PSOC). Results : In comparison with the mothers of normal children, the mothers of children with ADHD and IAD and the mothers of children with ADHD alone showed significantly higher levels of parenting stress and lower parenting efficacy. However, a comparison of mothers of children with ADHD and IAD with those of children with ADHD alone did not show any significant differences in their levels of parenting stress or efficacy. Conclusion : Mothers of children with ADHD, regardless of the presence of IAD exhibited a higher level of parenting stress and a lower level of parenting efficacy than mothers of normal children.

  • The order of Rhododendro-Quercetalia mongolicae representing temperate oak forests in Korea was characterized in terms of presence of taxa of different rank. 140 releves were analysed for percentage contribution of each species, genera and families in syntaxa under consideration as well as extracton of diagnostic genera and families for syntaxa by an ordination technique. The Rhododendro-Quercetalia is characterized by high diversity of tree and shrub species contributing 40% of the total floristic composition as well as by a high contribution of the genus Rhododendron and the absence of the genus Fagus, characteristic of the QuercoFagetea sensu lato. The character families for the Rhododendron and Quercus include Liliaceae and Compositae, whereas Acer, Carex, Viola, Rhododendron and Quercus are the most common among genera. Rhododendron and Quercus are regarded as the transgressive cheractergenera, whereas the families of Pinaceae and Ericaceae are considered companions (in sense of the terminology of the Braun-Blanquet syntaxonomy) for the order. Family appeared to be an inadequate rank for diagnoses of alliances and suballiances. On the other hand, genus was found to be the most effective rank in differentiating the alliances and suballiances. The Lindero-Quercenion shares the same character-genera with the order Rhododendro-Quercetalia. Character genera of the suballiances Callicarpo-quercenion are Carpinus, Styrax, Smilax and Callicarpa, and those of the Pino-Quercion list Euonymus, Saussurea and Tilia.

  • The purpose of this study was to examine the health status of the daughter and daughter- in-law caregivers who care for a cognitively and/or functionally impaired elderly, individual to identify factors that were related to reported health outcomes, and to investigate the negative and positive impacts of family caregiving. Data was collected from 120 daughter and daughter-in-law caregivers and care-recipients using face to face interviews. Most caregivers were daughters- in-law (77.5%) and most care-recipients were female (88.3%). Sixty-eight percent (n=81) of caregivers reported depressive symptomatology. General health also deteriorated by caregiving. Caregivers reported several negative impacts (difficulties): care-recipients' problematic behaviors, deterioration of their own health, pressure from social norms related to family caregiving in Korea, intrafamily conflict, and economic problems. Contrary to the popular belief, caregivers reported diverse positive impacts of family caregiving (68.3%): a sense of filial responsibilities, recognition from elderly, family members, relatives, and society, education for the children, and familial harmony. Higher depression score was predicted by lower family income, the presence of cognitive impairment of care-recipients, and higher level of social conflict of caregivers. Poor general health of caregivers was predicted by older caregivers' age, lower competing roles of caregivers, and poor emotional health. While not seeking to deny the negative aspects of family caregiving, it is also necessary to understand positive aspects of family caregiving to see complete picture of caring for an elderly family member.

  • The performance of a cognitive radio network (CRN) solely depends on how precisely the secondary users can sense the presence or absence of primary users. The incorporation of a spatial false alarm makes deriving the probability of a correct decision a cumbersome task. Previous literature performed this task for the case of a received signal under a Normal probability density function case. In this paper we enhance the previous work, including the impact of carrier frequency, the gain of antennas on both sides, and antenna heights so as to observe the robustness against noise and interference and to make the correct decision of detection. Three small scale fading channels: Rayleigh, Normal, and Weibull were considered to get the real scenario of a CRN in an urban area. The incorporation of a maximal-ratio combining and selection combing with a variation of the number of received antennas have also been studied in order to achieve the correct decision of spectral sensing, so as to serve the cognitive users. Finally, we applied the above concept to a traffic model of the CRN, which we based on a two-dimensional state transition chain.

  • This article presents a study on the concept of "Photogenie", which refers to the duality and mentality of the photographic image, with the viewpoint regarding the photographic image by Edgar Morin. First, we will look at the evolution of the concept of "Photogenie". From the field of photography, the term "Photogenie" means objects that produce light, enough to impress the photographic plate. But theorists of cinema at the beginning of the 20th century have changed the meaning of the term. For Louis Delluc, the "Photogenie" means the effect of union between the reproduction of real and artistic genius. For Jean Epstein, the "Photogenie" means mental quality, nonmaterial or inderterminable, of the photographic and cinematographic image. But Morin synthesized the arguements of Delluc and Epstein. For him, the "Photogenie" indicates both a double character of the photographic image and its mental quality. Then, based on this concept of "Photogenie," Morin said on particular aspects in the photographic image. Considering photography as a double in the anthropological sense, it puts emphasis not only the dual nature of the photographic image but also mental and spiritual quality. Combining the theory of the mage Henri Bergson and Jean-Paul Sartre, he builds his own theory of the mage that concerns both photography and cinema. In short, to Morin, the photographic image is a place where coexist absence and presence, the real and the imaginary, perception and memory, the material and mental, as well that a place of mentality which appear all our memories, hallucinations, dreams, imagination etc.

  • The flow pattern inside the inlet chamber of the tube side is one of the key parameters influencing on the performances of the shell-and-tube type of heat exchangers(STHE). In order to improve the flow distribution, the baffle shaped as the porous plate is installed in the inlet chambers. In the present study, numerical simulation has been performed to investigate the flow features of the tube side of the STHE in sense of the hydraulic performances. The flow fields have been analysed by the three-dimensional Navier-Stokes solvers with the proper turbulent models. Computational domain is ranged in the whole of the tube side of the STHE. The numerical results showed that the presence of the baffles improves the redistribution of the flow injecting to the tube bundels. The good agreements of the numerical results with the experimental results of PIV measurements have been shown for the validation of the numerical methods adopted in the present papers.

  • The purpose of this study was to determine the factors influencing the standing balance of independent ambulatory hemiparetic patients. The subjects of this study were 30 hemiparetic patients (18 males, 12 females) being treated as admitted or out patients at Severance Hospital Medical Center, all of whom agreed to participate in the study. In order to assure the statistical significance of the results, the paired t-test aid a Pearson's correlation were applied at the .05 level of significance. The results were as follows. 1. The difference in maintenance time of standing balance on a stable and unstable support surface was significant at the .05 level. 2. The difference in maintenance time of standing balance according to the control of visual and acoustic stimuli was significant at the .05 level. 3. The presence or absence of passive joint motion sense influenced the standing balance maintenance time. 4. There was no significant difference in the maintenance standing balance of the sound tower leg standing conditions according to spasticity, but the paretic lower leg standing conditions were significantly different (p<.05). This type of evaluation should be more widely used in the field of evaluating standing balance with hemiparetic patients. However, more extensive study and reports on various factors of standing balance are needed.

  • Various surgical procedures for the treatment of post-traumatic syringomyelia have been introduced recently, but most surgical strategies have been unreliable. We introduce the concept and technique of a new shunting procedure, syringo-subarachnoid-peritoneal shunt. A 54-year-old patient presented to our hospital with a progressive impairment of motion and position sense on the right side. Sixteen years before this admission, he had been treated by decompressive laminectomy for a burst fracture of L1. On his recent admission, magnetic resonance (MR) imaging studies of the whole spine revealed the presence of a huge syrinx extending from the medulla to the L1 vertebral level. We performed a syringo-subarachnoid-peritoneal shunt, including insertion of a T-tube into the syrinx, subarachnoid space and peritoneal cavity. Clinical manifestations and radiological findings improved after the operation. The syringo-subarachnoid-peritoneal shunt has several advantages. First, fluid can communicate freely between the syrinx, the subarachnoid space, and the peritoneal cavity. Secondly, we can prevent shunt catheter from migrating because dural anchoring of the T-tube is easy. Finally, we can perform shunt revision easily, because only one arm of the T-tube is inserted into the intraspinal syringx cavity. We think that this procedure is the most beneficial method among the various shunting procedures.
