SNS를 이용하는 사람들은 이를 통해 연결되어 있는 사람들에 대한 신뢰를 바탕으로 새로운 의견의 표출, 정보의 교환과 공유, 즐거움과 위안 등을 추구한다. 신뢰를 바탕으로 하는 새로운 네트워크의 형성과 관계 구축은 사회자본을 생성하고 구성하는 요인이라는 점에서 의미를 가 지며, 최근 기업들이 새로운 커뮤니케이션 수단으로 인식하면서 자사의 브랜드를 커뮤니케이 션 할 목적으로 브랜드 SNS를 많이 활용하고 있다. 본 연구는 최근에 대두되고 있는, 커뮤니케이션 측면의 강한 결속과 몰입을 의미하는 인게이 지먼트의 관점에서 브랜드 SNS를 연구하고자 한다. 브랜드 SNS의 어떤 특성이 궁극적으로 브 랜드에 대한 고객의 인게이지먼트를 높일 수 있는지를 연구하고자 하였으며, 브랜드 SNS의 특 성과 브랜드 인게이지먼트를 매개하는 요소로 미디어 인게이지먼트를 채택하였다. 그리고 미 디어 인게이지먼트가 브랜드 인게이지먼트에 미치는 영향을 증대시키는 조절변수로 미디어에 대한 신뢰를 선정하였다. 선행연구에 대한 검토와 전문가 심층면접 분석을 통해 정보 품질성, 정보 흥미성, 정보 접근성, 상호작용성이라는 4가지 브랜드 SNS의 주요 특성을 도출하였고, 이 들 변수가 미디어 인게이지먼트를 매개로 브랜드 인게이지먼트에 미치는 영향을 실증적으로 검증하였다. 마지막으로 미디어 인게이지먼트와 브랜드 인게이지먼트 사이에서 브랜드 SNS에 대한 신뢰가 미치는 조절효과를 검증하였다. Social networking sites(SNS) are places where users share information, market and promote their products and services, or find comfort simply by getting involved in activities that depend on their purposes. People use SNS for many different reasons but what is in common is that users basically have trust in others they stay connected with on social networking sites. Building trust through networks and developing new networks based on trust are factors that contribute to creating and constituting social capital. It is believed that people’s wants and needs for networking underlay the birth of SNS. They might have various reasons for networking, though trust in people and society made possible the dawn of SNS. Then social networking sites have evolved with a variety of characteristics in the historical background. A number of previous studies have explored the quality of SNS, such as service quality, information quality, and system quality. Taking a closer look at it, quality has a strong one-way concept in that quality is offered by providers to facilitate the use of people. Meanwhile, engagement, which is defined as strong bonds and commitment, has recently become a buzz word in marketing. A Korean term for engagement has yet to be determined so it is just transliterated into Hangeul, and it commonly refers to various notions such as commitment, participation, involvement, and attachment. Engagement has become compartmentalized into media engagement, brand engagement, consumer engagement, and information engagement. Given the underlying features of social capital, information quality, enjoyment, perceived ease of use, and interaction, the four characteristics of SNS, were selected for this study as independent variables from the perspective of marketing communication. In this study, media engagement mediated between dependent variable brand engagement and the four independent variables. To sum up, the characteristics of brand SNSs, information quality, enjoyment, the perceived ease of use, and interaction all had effects on media engagement. It was also found that media engagement was an effective leading variable for brand engagement. Media engagement mediated between brand engagement and the four characteristics of SNS, information quality, enjoyment, perceived ease of use, and interaction. In addition, reliability moderated between media engagement and brand engagement.

다한증환자에서 제 2 흉부 교감신경 절단술이 Q-T 간경에 미치는 효과

Background : Thoracoscopic sympathicotomy was, at first, thought to be a simple and safe method for treatment of hyperhydrosis. However, few studies refer to the cardiac effects of this procedure, despite the fact that the T2 ganglia are in the direct pathway of the sympathetic innelvation of the hear. An imbalance of right and left sympathetic efferent activity has been proposed as a mechanism for arrhythmia in patients with long QT syndrome. The aim of this study was to compare hemodynamic effect as well as ECG changes after right and leal side sympathicotomy. Methods: 42 patients with essential hyperhydrosis in ASA physical status class 1 undergoing thoracoscopic sympathicotomy were randomly divided into two groups: left side first operation group (group L, n = 22) and right side first operation group (group R. n = 20). Anesthesia was induced with thiopental sodium (5 mg/kg) and pancuronium (0.05 mg/kg) and maintained with enf1urane. During the procedure, we recorded blood pressure at both forearms and heart rate and ECG were recorded after anesthetic induction as baseline values, immediately after one side resectioned of sympathetic trunk, and after complete resectioning of both sids. All operations were done with usual methods by experienced surgeons. All the records were coded and analysed singl blind by one author. Results : After sympathicotomy, there was a significant decrease in hear rate but not in blood pressure. However, stati,itically there were no significant changes in QT interval during sympathicotomy either right side first operation or left side first operation. Conclusions: The main result of this study was that there were no significant changes in QT interval during sympathicotomy of either right or left side first operations. However, This does not mean that there was no pofibility of prolongation of QT interval during thoracoscopic sympathicotomy. Careful observation of QT interval changes is needed during sympathicotomy. (Korean J Anesthesiol 2000; 38: 76∼80)

Objectives: The clinical manifestations of gout in Korea would be changed lately according to the rapid economical development and the development of diagnostic methods. This study was done to reveal the late clinical features of gout in Korea. Methods: A retrospective study was done for the 90 gout patients who had been treated in Seoul Paik Hospital from March 1974 to August 1994. Age of onset, sex, duration of disease, serum uric acid level, uric acid concentration of 24 hour urine, joint of first attack, recurrently involved joints, X-ray of involved joint, frequency of tophi, renal ultrasonography, and associated diseases were analyzed. The uric acid levels of the 808 civilians who visited our hospital for the periodic health examination were used as a control value. Results: 1) The serum uric acid level in Korean adults was 5.2±1.1mg/dL in male, 3.8±0.7mg/dL in female, and 4.7mg/dL in general. The serum uric acid concentration of the gout patients was 8.6±2.2mg/dL in male, 6.1±2.1mg/dL in female, and 8.5±2.3mg/dL in general. The age of onset was 46.4±12.9 years old and male to female ratio was 44: 1 2) The renal excretion of uric acid was 470±173 mg/day in gout patients. 3) The sites of first attack were first MTP joint(76%), tarsal joint(13%), knee(5%), and other MTP joints(5%) 4) The involved joints during the repeated attacks were first MTP joint(84%), tarsal joint(23%), and fingers(23%), The duration of disease was significantly longer and the serum uric acid concentration was higher in the patients with tophi than they are in the patients without. 5) The 4l% of patients showed hone change in X-ray. 6) The renal ultrasound examinations were abnormal in 42% of the patients and the serum uric acid concentrations were significantly higher. 7) Obesity was found in 68% of patients, hypertension in 39%, hyperlipidemia in 16%, and chronic renal disease in 12%. Conclusion: The clinical features of gout in our study were similar to those of others done in and out of Korea, except that the frequency of hypertringlyceridemia was much lower than that of the foreign countries.

Background : Thoracoscopic sympathicotomy was thought to be a simple and safe method for hyperhidrosis. There is a significant decrease in heart rate during the procedure, Also it has been suggested that the effect of the degree of sympathetic block on cardiac function was affected by the preoperative level of sympathetic activity. Our hypothesis was that the higher heart rate before sympathicotomy the more heart rate change during the procedure because heart rate is one of the indicators of sympathetic activity. Methods: Sixty two patients with essential hyperhidrosis undergoing thoracoscopic sympathicotomy were studied. During the procedure, we recorded blood pressure at left arm and heart rate after anesthetic induction as baseline values, immediately after left side sympathicotomy, and after right side sym- pathicotomy. Patients were divided by median value of preoperative heart rate (83 beats/min) into group I (n = 32), preoperative heart rate below 83 beats/min, and group II (n =30), above 83 beats/min. Results : The preoperative mean heart rates of group I and 1I were 72 ± 7.9 beats/min and 100 ± 12.5 beats/min respectively. After sympathicotomy, the decrease of heart rate compared to the pre-operative value in Group I was 6.6%, which was significantly lower than that of Group II, 17.6%. After left sympathicotomy, the number of cases of heart rate decreasing more than 10% was higher in Group II (20/30 cases) than Group I (13/32 cases). Conclusions: The main result of this study showed that the higher heart rate before sympathicotomy the more heart rate change during procedure. (Korean J Anesthesiol 2000; 39: 67~71)

Objective : We attempted to investigate the psychiatric characteristics of fibromyagia syndrome and to determine whether these characteristics are similar with those of major depression or somatoform disorder. Objects and Methods : Twenty-three fibromyalgia syndrome patients, 25 osteoarthritis, 39 rheumatoid arthritis, 25 somatoform disorder and 20 major depression patients were studied. Medical College of Wisconsin Center Pain Follow up Questionnaire, Global Assesment of Recent Stress Scale (GARS), Beck Depression Inventory (BDI), State and Trait Anxiety Inventory and Korean standardized edition of Eysenck Personality Questionnaire were used for assesement. Results : 1) In fibromyalgia group, the intensity of pain at its worst severity was significnatly higher than that of rheumatoid arthritis and osteoarthritis group and the pain more persistent than the other groups. 2) Mean scores of several items including overall global stress perception of fibomyalgia and major depression group were higher than those of the other groups. 3) Among the personality characteristics, scores for psychoticism and neuroticism of fibomyalgia and major depression group were higher than those of the other groups and profile of personality charaterisctics was also different among fibomyalgia, major depression group and the other groups 4) In spite of statistical non-significance, total score of BDI was higher in fibomyalgia and major depression group than the other groups and that score was regarded as having a severe depression. In factor 3 of BDI (pessimism-suicide) which was the main fectors of depression psychology, fibomyalgia and major depression group were scored significantly higher than the other groups. 5) In fibromyalgia and major depression group, score of trait anxiety was also significantly higher than that of the other groups but score of state anxiety was higher in fibromyalgia, major depression, and somatoform disorder group in order. Conclusion : These results suggest that patients with fibromygia syndrome show a distinguishable psychological characteristics to compare with patients with rheumatoid arthritis and osteoarthritis. The fibromyalgia patients seem to be more painful, more stressful, more anxious, and more depressed than other arthritis patients and they have characteristic personality traits and profiles. And that they show similar psychological profiles with those of major depession rather than those of somatoform disorder

A secondary amyloidosis is AA amyloidosis and rheumatoid arthritis is one of the main underlying diseases. We report a case of secondary amyloidosis in a patient with rhrumatoid arthritis. She had suffered from rheumatoid arthritis for 8years and her hands and feet were deformed. Hemoglobin was 8.7g /dl, hematocrit 25 vo1%, WBC 7700/mm3, ESR 44mm/h. In urinalysis protein was 3+ and 20-25 RRC were seen in 400x microscopic field. Total protein of 24hour urine was 696 mg and Ccr was 62ml/ min. The blood BUN and creatinine level were nor- mal. The serum level of rheumatoid factor was 316 IU/ml( <40), CRP 1.1mg/dl and ANA test was negative. In abdominal sonography spleen, liver and kidneys were enlarged(spleen 15.1cm, right kidney 10.9cm, left kidney 12.2cm). A green colored positive birefringent amorphous material was found in polarizing microscopy of the rectal biopsy specimen stained with congo red. But the congo red staining of the specimen pretreated with potassium permanganate did`nt show any green birefringent material. We couldn`t find any previous report of the secondary amyloidosis(AA amyloid)among the patients with rheumatoid arthritis in the Korean literatures.

Gout is known to show such as an increase in the serum urate concentration, recurrent attacks of a characteristic acute arthritis, in which crystals of monosodium urate monohydrate are demonstrable in leukocytes of synovial fluid, tophi chiefly in and around the joints of the extrimities and sometimes leading to severe crippling and deformity, renal disease involving interstitial tissues and blood vessels, and uric acid nephrolithiasis. We report a case of gout associated with hereditary spherocytosis of which any official report couldn't be found in the world literatures. A 31 year old man was hospitalized because of recurrent multiple joint pain and multiple joint deformities. He had multiple periarticular tophi, and the joints in hands and feet were deformed. The hemoglobin level was 4.7 gm/dl, hematocrit 12.5%, total and direct bilirubin level were 4.0 mg/dl and 0.8 mg/dl, serum uric acid level was 8.3 mg/dl, and the uric acid excretion in 24 hour urine was 773 mg/day. In abdominal ultrasonography, the kidney showed thinning of the cortex, homogeneously incresed echogenicity of medulla and the liver and spleen were markedly enlarged, and several stones were found in gall bladder. The renal function was normal. In peripheral blood smear 10-15 spherocytes were seen per high power field. The osmotic fragility curve revealed uniformly increased osmotic fragility in osmotic fragility test of incubated red cells. From these data we think that the overproduction of uric acid due to the hereditary spherocytosis and the idiopaihic underexcretion of uric acid in the kidney caused chronic tophaceous arthritis and urate nephropthy.
