  • 소셜 네트워크 서비스(SNS)의 사용이 사회 전반으로 확대되면서 사용자들은 더욱 더 다양하고 많은 개인정보를 SNS에 제공하고 있으나 이러한 정보를 불법적으로 사용하는 사례 또한 늘어나고 있다. 따라서 사용자들의 프라이버시 침해 우려는 지속 사용 의도를 방해하는 가장 큰 요인이 되고 있다. 기존의 연구들은 사용자들의 SNS 사용을 유도하기 위해 이러한 프라이버시 침해 우려 자체를 줄이는데 초점을 맞추어 왔다. 그러나 본 연구에서는 사용자의 SNS 지속 사용 의도를 적절히 이해하기 위해서는 프라이버시 침해 우려를 줄이려는 시각에서 접근하는 것도 중요하지만, 사용자가 인지하는 이득을 증가시키는 시각의 접근법이 같이 수반되어야만 한다고 제안한다. 따라서 프라이버시 계산 모형을 이론적 틀로 하여, 사용자가 인지하는 이득으로 네트워크 형성지원과 네트워크 외부성을 제안하고 여기에 덧붙여 SNS 제공업체에 대한 신뢰의 역할을 살펴보는 연구 모형을 제안하였다. 이를 검증하기 위해 150명의 페이스북 사용자와 150명의 카카오톡 사용자를 대상으로 횡단 설문 연구를 실시하였다. 그 결과 SNS 제공업체에 사용자가 가지는 신뢰는 네트워크 외부성과 지속 사용 의도 관계, 프라이버시 침해 우려와 지속 사용 의도 관계, 이 두 가지 관계에서 매개 역할을 하였다. 그러나 네트워크 형성 지원은 페이스북 사용자의 지속 사용 의도에는 유의한 영향을 미쳤지만, 카카오톡 사용자에게는 유의한 영향을 미치지 않는 것으로 드러났다.

  • To evaluate age and gender differences in the relation of cardiovascular risk factors, cognitive impairment, and subclinical carotid atherosclerosis from aged people using by a cross sectional method. Sixty-nine healthy elders living in the community who had not previously undergone carotid ultrasonography were included. We conducted life style surveys, and cognitive function tests including Korean-mini-mental state examination (K-MMSE) and clinical dementia rating-Korean. Various biomarkers from blood were assessed; fasting insulin-like growth factor-1, lipid-profile, high sensitivity C-reactive protein, total homocysteine, glucose, insulin, Homeostasis model assessment (HOMA) for insulin resistance index, vitamin B12, and folate level. Carotid intima-media thickness (C-IMT), and plaques were measured using carotid ultrasonography and aortic ultrasonography, a valid index of atherosclerosis. For the elderly subjects (aged 65-82 years), cognition impairment was more prevalent in females while subclinical atherosclerosis was more prevalentin males. Increased C-IMT has been kept in males, and C-IMT shows increasing trend and the peak at about 80 year-old in females with increasing age. The significant correlations between C-IMT and many vascular risk factors including age, triglyceride, abnormal homocysteinein male, and K-MMSE, insulin, HOMA index and abnormal aortic ultrasonography in female were different in each gender, with the exception of homocysteine (p<0.05). This data suggests that there were differences of age and gender characteristics in terms of subclinical atherosclerosis, cognitive impairment and vascular risk factors in community-living elders. Further larger and longitudinal studies across entire age are required to better understand the effects of risk factors on subclinical atherosclerosis.

  • Background : Complementary and alternative medicine has bee used to cardiovascular diseases. In recent years, many hospitals have tried to integrate complementary and alternative medicine(CAM) with conventional medical approaches for patients with chronic diseases. Recently, the prevalence of the use of traditional Korean medicine(TKM) among patients with chronic diseases, expecially, hemiplegia patients after cerebrovascular accident is increasing in Korea. To date, however, there were only few studies addressing the patients' attitudes, and utilization of TKM, compared to the well-documented escalating use of TKM among consumers in Korea. Objectives : The objective of this study was to analyze the prevalence of TKM use among hemiplegia patients after cerebrovascular accident and to determine what factors affect to use CAM among the patients. The study also aims to provide information on TKM and assist therapy selection among various CAM therapies for hemiplegia patients after cerebrovascular accident within health care system in which both practitioners of TKM and practitioners of modern Western medicine coexisted. Methods : The design of the study was descriptive cross-sectional, and data were collected using a 32-items questionnaire. The subjects were one hundred fifty nine patients with chronic diseases who visited or admitted to health care facilities in a hospital in Seoul Metropolitan city, Korea. Data were analyzed using 'SPSS Statistics 18.0 Network Version(on release 18.0.1 of PASW Statistics)' program. Various statistical methods were used to obtain a profile for participants and the therapies most frequently used by hemiplegia patients of TKM. Logistic regression analysis was employed in order to determine the predicting variables of TKM use. Results : The prevalence of the use of TKM was 51.6%. The most common TKM therapies used by the patients included acupuncture(93.2%), herbal medicine(64.8%), and cupping(37.5%). Results of logistic regression analysis revealed that the variables significantly related with TKM use were gender, marital status, job, No. of visiting health care facilities/week. Conclusions : This study shows that the use of TKM among the hemiplegia patients is relatively high in Korea, this topic should be taken into account in the development of a holistic approach for patients with chronic diseases and an efficient chronic disease management system in Korea.

  • Objectives : The aim of this study was to investigate the association of blood pressure levels with the common carotid artery intima-media thickness (CCA-IMT) and carotid plaques. Methods : Data were obtained from 2,635 subjects, aged 50 years and over, who participated in the Community Health Survey (a population-based, cross-sectional study) in Dong-gu, Gwangju city between 2007 and 2008. Participants were categorized into three groups according to blood pressure levels; normotensives (<120/80 mmHg), prehypertensives (120-139/80-89 mmHg), and hypertensives ($\geq$140/90 mmHg). Prehypertensives were further categorized as low prehypertensives (120-129/80-84 mmHg) and high prehypertensives (130-139/85-89 mmHg). Carotid intima-media thickness and plaques were evaluated with a high-resolution B-mode ultrasound. Statistical analyses were performed using chi-square test, ANOVA, and multiple logistic regression. Results : Prehypertensives had significantly greater maximal CCA-IMT values than normotensives, with a multivariate adjusted odds ratio of 1.78 (95% CI=1.36-2.32) for abnormal CCA-IMT (maximal CCA-IMT$\geq$1.0 mm), and 1.45 (95% CI=1.19-1.77) for carotid plaques. The multivariate adjusted odds ratio of low prehypertensives was 1.64 (95% CI=1.21-2.21) for abnormal CCA-IMT, and 1.30 (95% CI=1.04-1.63) for carotid plaques compared with normotensives. Subject with hypertension had higher frequency of abnormal CCA-IMT (odds ratio, 2.18; 95% CI=1.49-3.18), and carotid plaques (odds ratio, 1.98; 95% CI=1.46-2.67) compared with normotensives after adjustment for other cardiovascular risk factors. Conclusions : Our results indicate that there is a significant increase in the prevalence of carotid atherosclerosis in subjects with prehypertension (even in low prehypertensives) compared with normotensive subjects. Further studies are required to confirm the benefits and role of carotid ultrasonography in persons with prehypertension.

  • Opportunistic screening for lung cancer is commonly conducted in Korea in accordance with physician recommendations and screenee's preferences. However, studies have yet to thoroughly examine the public's understanding of the risks posed by lung cancer screening. This study was conducted to assess changes in intentions to undergo lung cancer screening in response to being informed about exposure to radiation during low-dose computed tomography (LDCT) tests and to identify factors with the greatest influence thereon among Korean men. We conducted sub-group interviews among men chosen from the 2013 Korea National Cancer Screening Survey (KNCSS), a nationwide, population-based, cross-sectional survey of men aged 40 to 74 years and women aged 30 to 74 years. From 4100 participants in the KNCSS, 414 men who underwent any cancer screening test within the last 2 years were randomly selected for inclusion in this study. Via face-to-face interviews, their intentions to undergo lung cancer screening were assessed before and after being informed about exposure to radiation during LDCT testing. Of the 414 participants, 50% were current smokers. After receiving information on the benefits of the test, 95.1% stated an intention to undergo screening; this decreased to 81.6% after they received information on the harms of the test. The average decrease in intention rate was 35.3%. Smoking status, household income, and education level were not associated with lowered intentions to undergo lung cancer screening. Participants who were older than 60 years old (OR=0.56; 95% CI= 0.33-0.96) and those with less concern for radiation exposure (OR=0.56; 95% CI=0.36-0.89) were less likely to lower their screening intentions. The results of this study suggest that there is a need to educate both non-smokers and former smokers on the harms of lung cancer screening.

  • Background: There is paucity of studies defining the prevalence of non-communicable disease (NCD) risk factors in Saudi Arabia despite the surging epidemic of obesity, change in dietary habits and sedentary lifestyle. Objectives: This cross-sectional study aimed to assess the prevalence of NCDs risk factors among employees at King Faisal University in Al Hassa, Saudi Arabia and to determine the possible correlates for clustering of NCDs risk factors among them. Materials and Methods: All employees were invited to participate; the World Health Organization STEPwise approach was used for data collection which consisted of a personal interview to collect socio-demographic characteristics, NCD history, tobacco use, vegetables and fruit consumption, and physical activity (PA), followed by anthropometric measurements namely weight, height and waist circumference and blood pressure measurements, subjects were finally subjected to biochemical tests with determination of fasting plasma glucose, serum triglycerides, cholesterol and high density lipoproteins. Results: Of the surveyed employees (n=691), daily current smokers accounted for 22.7%. 94.9%, 95.1% and 86% consumed < 5 servings per day of vegetables, fruits and both fruits and vegetables respectively, 73% were physically inactive, 64% were overweight or obese, 22.1% had hypertension, and 21.5% were diabetics. Elevated cholesterol levels were found in 36.6%, low high density lipoproteins in 36.8%, and elevated triglycerides in 36.1%. Only 3% had no NCD risk factors, and 57.6% had ${\geq}3$ factors. Multivariate logistic regression showed that gender (being male, adjusted odds ratio 'aOR'=1.51), aged ${\geq}50$ years (aOR=3.06), < college education (aOR=1.75), current smokers (aOR=2.37), being obese (aOR=6.96) and having a low PA level (aOR=4.59) were the significant positive predictors for clustering of NCD risk factors. Conclusions: Over fifty percent of the studied university's employees had multiple (${\geq}3$) NCD risk factors. Screening and health promotion initiatives should be launched at least targeting the modifiable factors to avert the excessive risk for cardiovascular disease, diabetes mellitus and several types of cancers.

  • With the accumulations of outcomes from archaeological excavations of mountain fortress of three kingdoms period, there have been studies about time-periodic territory range of mountain fortress, difference in the way(method) of construction, defence system and so on from various points of view. This is an empirical study on the construction method of the valley part of stone fortress. First of all, it is required to secure large quantity of fresh water for those who lived at mountain fortress. Especially when builders of fortress construct a fortification at the valley part of stone fortress, in advance they must sufficiently consider several options including the establishment of sustainable water resources. First, when it comes to build a fortification on a ridge[or a slope] of a mountain, you have only to consider a vertical stress. However, when it comes to build a fortification at the valley part of a mountain, You must have more sufficient preparations for the constructing process. Because there are not only a vertical stress but also a horizontal pressure simultaneously. Second, a fortification of mountain fortress built by using unit building stone is a structure of masonry construction like brick construction, and the valley part of it is where the construction of the fortification begins. Third, when it comes to build a fortification at the valley part of a mountain, it seems that they use a temporary method such as coffer dam in oder to prevent the collapse of the fortification due to heavy rain. Furthermore, in response to a horizontal pressure a fortification is built by the way of its plane make an arch, or by piling up the soil with the plate method(類似版築) and earthen wall harder method(敷葉) they increase cross-sectional area of the fortification and its cutoff capacity. In front direction they put the reservoir facility for the fear that the hydraulic pressure and earth pressure are directly transmitted to the fortification. The process of constructing the fortification at the valley part of a mountain is done in the same oder as follows; leveling of ground(整地) ${\Rightarrow}$ construction of coffer dam ${\Rightarrow}$ construction of the fortification between the both banks of the valley ${\Rightarrow}$ construction of the fortification at bottom part of spill way(餘水路) between the both banks of the valley ${\Rightarrow}$ construction of spill way(餘水路) & reservoir facility ${\Rightarrow}$ construction of the fortification at upper part of spill way between the both banks of the valley. Coffer dam facility seems to be not only the protection device on occasion of flood but also an important criterion to measure the proper height of spill way or tailrace(放水路). This study has a meaningful significance in that it empirically examines the method of reduction of the horizontal pressure which the fortification at the valley part of a mountain takes, the date the construction was done, and wether the changes in climate such as heavy rainfall influence the process of construction.

  • 본 연구는 K대학교에서 비만 또는 과체중 학생을 대상으로 4주간 운영하는 체중조절 프로그램에 개입하여 프로그램 전후의 비만지표 변화와 치주지표 변화를 조사하고 분석하였다. 그 결과, 체중, 허리둘레, 체질량지수, 체지방률, 복부지방률은 모두 유의하게 감소하였고 치면세균막지수는 유의하게 증가하였으며 치은지수, 탐침시 출혈부위수, 천치주낭부위수는 유의한 변화가 없었다. 성별, 흡연, 음주의 특성이 비만지표 변화와 치주지표 변화에 영향을 미치지 않았다. 그러나 프로그램 전후 차이 지표 변화의 상관분석에 체지방율 변화와 탐침시 출혈부위수 변화가 강한 양의 상관관계를 나타내었고 복부지방률 변화와 천치주낭 부위수 변화가 중정도의 양의 상관관계를 나타내었다. 탐침시 출혈 부위수 변화에 대한 체지방률의 설명력은 58.9%로 나타났다. 따라서 체지방률과 복부지방률이 치주 임상지표와 연관성이 있으며, 비만 감소는 치주 건강에 영향을 끼칠 수 있다고 제안한다.
