As the tourism activity of tourists increases at nighttime, the importance of experience is rising in the night scenery of cultural heritage buildings. Due to the economic and cultural importance of the tourism phenomenon that experiences the night scenery focusing on the spatial background of cultural heritage sites, many domestic and international scholars are paying attention to research subjects related to night view in various fields. However, there is a lack of research on night scenery in the field of tourism. The purpose of this study is to analyze the difference of causality between authenticity and tourism satisfaction with tourists who viewed day and night scenery of cultural heritage site. The subject of this study is Deoksugung Palace located in Seoul, Korea. Deoksu Palace is open all the time at night, and this place is expected to be the best place to analyze the difference of day scenery and night scenery in cultural heritage. First, both sub-dimensions of authenticity positively influenced tourism satisfaction, Objective authenticity has a more significant effect than existential authenticity. Second, the results of analyses show that there is moderating effect on authenticity and tourism satisfaction according to the experience of day scenery and night scenery. In other words, this implies that objective authenticity in the experience of day scenery and night scenery shows the influence difference in tourism satisfaction. This study is to contribute to the sustainability of cultural heritage tourism related to night scenery while suggesting academic and practical implications. It can be meaningful to quantitatively validate the relationship between authenticity and tourism satisfaction about landscape experience that has been mainly approached qualitatively in other fields. The purpose of this study is to investigate the causal relationship between objective authenticity and tourism satisfaction in the cultural tourism of day and night. This emphasizes the importance of night scenery and provides an opportunity to utilize it as a major element of tourism marketing.

Background: Small subcortical infarctions of basal ganglia can be divided into either lacunes or striatocapsular infarctions by size of lesion. However, there are some controversies concerning the size criteria of lacune and striatocapsular infarction. To better understand differences among these patients, we elucidated clinical and other properties of deep small basal ganglia infarctions (DSBIs), which could not be clearly classified as either lacunes or striatocapsular infarction by their sizes only. Methods: We analyzed 27 patients with acute ischemic lesion of basal ganglia with which the size varying from 1.5 cm to 3 cm in their maximal diameters. We assessed clinical features, laboratory data, stroke risk factors, and radiologic findings such as MRI and MR angiography. Results: These patients could be largely divided into two distinct groups, either with or without associated cortical symptoms and signs. The most common clinical feature was motor weakness that was found in all but one patient. Sensory disturbances, altered deep tendon reflexes, and positive Babinski signs were also commonly found. Ten of the 27 patients showed cortical manifestations such as eyeball deviation, visual field defect, aphasia and neglect. Eight of the 10 patients with cortical manifestations showed MCA or ICA stenotic lesions. Conclusions: We found that many patients with 1.5 cm to 3 cm sized DSBIs could have the features of either lacune or striatocapsular infarction. Careful evaluation of clinical and radiologic findings should be performed in patients with clinically appearing lacunar syndrome in order to differentiate lacunar infarction of small vessel disease from striatocapsular infarction of other various pathophysiologies. Echocardiogram, cerebral angiogram and perfusion and diffusion MRI could be recommended for further evaluation and to better understand the pathogenesis in these patients.

Purpose: In spite of higher incidence of stroke in end-stage renal disease (ESRD) patients compared to general population, the risk factor for stroke which is specific to ESRD is not fully understood. The ESRD patients who develop stroke may have certain additional risk factors compared to ESRD patients without stroke. We used registered data of Hallym Stroke Registry to elucidate the factors which affect development of ischemic stroke among the dialysis patients. Materials and Methods: We recruited patients with acute ischemic stroke in ESRD patients undergoing maintenance dialysis. Dialysis patients without stroke were selected as control group with age and gender matching. We compared the demographic features,stroke risk factors, and laboratory findings in ESRD patients with or without ischemic stroke. Results: The total of 25 patients with ESRD developed ischemic stroke. Fifty ESRD patients without stroke were chosen as the control group. The mean age of acute ischemic stroke patients was 59.80±9.94 and male gender was 48%. The most common ischemic stroke subtype was small vessel occlusion (n=12), followed by large artery atherosclerosis (n=7). The patients with stroke had more frequent history of hypertension and higher systolic/diastolic blood pressure at the time of admission than the ESRD patients without stroke. Total cholesterol and LDL-cholesterol levels were significantly lower in the stroke group. In multivariate analysis, LDL-cholesterol was found to be the only risk factor for ischemic stroke. Conclusion: The results of our study reveal that LDL-cholesterol is associated with greater risk for ischemic stroke in the patients on dialysis.

This study aims to understand the overall perception of the South Korean national baseball team in the 2023 World Baseball Classic (WBC) and provide insights for improving public perception and marketing strategies for the WBC tournament. Using the TextoM big data processing solution, various analyses were conducted on data collected from Naver, Daum, and Google during different WBC phases. The research findings are as follows: Firstly, keyword analysis revealed that before the WBC opening, the predominant keywords revolved around information about the South Korean national baseball team, training, broadcasting, while during the WBC tournament, the focus shifted to participating countries, players, match schedules, and results. After the WBC's conclusion, keywords were related to tournament information, the start of the professional baseball season, and team performance issues. Secondly, network visualization and CONCOR analysis unveiled distinct groupings during different phases. Prior to the WBC opening, there were four groups comprising the South Korean national baseball team, WBC match issues, training, and commentary. During the WBC tournament, five groups emerged, including the South Korean national baseball team, WBC match issues, match results, WBC opening, and national team retirements. After the WBC's conclusion, four groups surfaced, involving the South Korean team's performance, downturn, Asian Games preparation, and match issues. Based on these results, this study aims to contribute to public perception analysis research and the development of the domestic sports industry by suggesting improvements in public perception and WBC activation strategies.

With the global spread of COVID-19, there have been constraints on tourism behavior, which are increasing the negative emotion of tourists. To recover from this negativity, tourists are pursuing domestic nature-based travel as much as possible in the current situation. This study aims to empirically confirm whether natural tourist destinations have the effect on helping tourist recover from COVID-inspired negativity and if perceived happiness is enhanced for those who traveled to natural tourists destination during the COVID-19 pandemic situation. In order to test the hypothesized model, data were collected from an online survey from September 5th to September 19th. A total of 742 of 845 responses were used for empirical analysis. The results of the study are as follows. First, it was found that physical risk perception did not affect perceived restorative environment, while psychological risk perception and socio-environmental risk perception had an impact on perceived restorative environment. Second, it was found that the perceived restorative environment had an impact on perceived attention restoration. Third, it was found that the perceived attention restoration had an impact on travel happiness (subjective well-being). This study is meaningful in that it theoretically verified the importance and positive role of domestic nature-based tourist destinations in a psychologically negative state. Based on the results of the study, natural tourism destination development directions were proposed for tourism business corporales and public institutions. 코로나19의 전 세계적 확산으로 관광 활동에 제약이 생겨 관광객들의 부정적 심리가 증가하고 있다. 이를 회복하기 위해 여행객은 현 상황에서 가능한 국내 자연기반 여행을 추구하고 있다. 이에 따라 코로나19 거리두기 기간에 자연관광지를 여행한 사람을 대상으로 자연대상 관광지가 관광객의 부정적 심리를 회복하고 행복을 지각하게 하는 효과가 있는지 실증적으로 확인하고자 한다. 이 연구를 위해 코로나 거리두기 기간에 자연기반 관광지를 방문한 경험이 있는 관광객을 대상으로 2020년 9월 5일부터 2019년 9월 19일까지 온라인 설문조사를 진행하였고, 845부 중 742부를 실증분석에 사용하였다. 분석은 기술 통계분석, 분산분석, 확인적 요인분석, 구조방정식 등을 하였다. 연구 결과는 다음과 같다. 첫째, 신체적 위험지각은 회복환경지각에 영향력이 없는 반면 심리적 위험지각 및 사회·환경적 위험기각은 모두 회복환경지각에 영향력이 있는 것으로 나타났다. 둘째, 회복환경지각은 주의회복에 영향력이 있는 것으로 나타났다. 셋째, 주의회복은 여행행복에 영향력이 있는 것으로 확인되었다. 심리적으로 부정적 상태에서 여행공간으로써 국내 자연기반 관광지의 중요성과 긍정적 역할을 이론적으로 검증하고 확장하였다는 점에서 이 연구는 의의가 있다. 연구 결과를 토대로 국내 자연 관광지 개발 및 마케팅을 진행할 예정인 사업체나 기관이 자연 관광지의 발전 방향을 설정하는데 의미 있는 시사점을 제시하고자 하였다.

정산진 한국약용작물학회 2003 韓國藥用作物學會誌 Vol.11 No.5

The influences of the extracts from Cinnamomi cortex, Eucommiae Cortex, Puerariae Radix, Lycii Fructus, Zixyphi Fructus, Schisandrae Fructus, Mume Fructus, Chaenomelis Fructus on mycelial growth and aflatoxin B1 production from Aspergillus parasiticus were analyzed. The pH of the culture media were redeced to below pH 4 by all the herbal extracts after 3 days incubation. However, the pH of the culture media increased above pH 6 after 6 days incubation using the extracts from Cinnamomi Cortex, Eucommiae Cortex, Puerariae Radix and Lycii Fructus. The mycelial growth of A. parasiticus was increased over the amount of the control. Puerariae Radix produced the largest amount of mycelial growth and Chaenomelis Fructus produced the smallest amount of mycelialgrowth. The productions of aflatoxin B1 from A. parasticus culture were increased by the extracts of Puerariae Radix and Zizyphi Fructus, while inhibited by the extractso of Cinnamomi Cortes, Eucommiae Cortex, Lycii Fructus, Schisandrae fructus, Mume Fructus and Chaenomelis Fructus. In particular, the extracts of Cinnamomi Cortex, Lycii Fructus and schisandrae Fructus almost inhibited the preduction of aflatoxin b1. The production of the total protein from Cinnamomi Cortex, which produced much less aflatoxin B1, and Puerariae Radix, whichproduced a great deal of aflatoxin B1 from A. parasticus were slightly higher than the production of the total protein of the control medium.

소뇌 소경색의 임상 양상과 발병 기전

정산 대한뇌졸중학회 2001 Journal of stroke Vol.3 No.2

Background : In the cerebellum, small(〈2 cm in diameter)infarcts have recently been reported as having different pathogenic mechanisms from supratentorial small ischemic lesions. However, it is unclear only with simple MRI or conventional CT scan whether they are lacunar infarcts or borderzone infarcts. The purpose of this study was to elucidate the pathophysiological mechanism and the clinical nature of small cerebellar infarcts. Methods : We analyzed consecutive patients admitted to the Hallym stroke center between 1994 and 1999. Among them, we selected ischemic cerebellar stroke and classified them into large territorial, small non-territorial and mixed types according to their infarct sizes. We studied clinical and MRA findings and pathogenic mechanisms in each type of the cerebellar infarcts. Results : Forty-seven patients were selected for the study. Twenty-one cases were classified as large territorial infarcts, 18 patients as small non-territorial cerebellar infarcts. The Mixed form included 8 patients. Patients with large territorial infarcts and those with small cerebellar infarcts had similar risk factors, laboratory findings and clinical features. As for the causative mechanisms, small cerebellar infarcts had similar proportion of large artery disease(66.7% vs. 55.7%) and cardiac embolic source(16.7% vs. 28.6%) when compared to large territorial infarcts. Conclusion : Although the radiologic findings of small cerebellar infarcts resemble supratentorial lacunar lesion, the small cerebellar infarcts have heterogenous etiologies. Diagnostic studies and management of small cerebellar infarcts should be based on the understanding of these observations. Korean Journal of Stroke 2001;3(2): 124~130
