  • Background: Gastric cancer is the second most common gastrointestinal cancer and is largely attributed to Helicobacter pylori (H. pylori) infection. In addition, studies have also shown association with Epstein-Barr virus (EBV) in 10% of gastric cancers. This study assessed the characteristics of EBV associated gastric cancers (EBVaGC) in Brunei Darussalam. Materials and Methods: This study included gastric cancers diagnosed between 2008 and 2012, registered with the Department of Pathology RIPAS Hospital, Brunei Darussalam. Clinical case notes were systematically reviewed. Histology specimens were all stained for EBV and also assessed for intestinal metaplasia and H. pylori. Results: There were a total of 81 patients (54 male and 27 females) with a mean age of $65.8{\pm}14.8years$ included in the study. Intestinal metaplasia and active H. pylori infection were detected in 40.7% and 30.9% respectively. A majority of the tumors were proximally located (55.6%), most poorly differentiated (well differentiated 16%, moderately differentiated 30.9% and poorly differentiated 53.1%) and the stages at diagnosis were; stage I (44.4%), stage II (23.5%), stage III (8.6%) and stage IV (23.5%). EBV positivity (EBVaGC) was seen in 30.9%. Between EBVaGC and EBV negative gastric cancers, there were no significant differences (age, gender, ethnic group, presence of Intestinal metaplasia, tumor locations, stages of disease and degree of tumor differentiation). Conclusions: This study showed that a third of gastric cancers in Brunei Darussalam were positive for EBV, higher than what have been reported in the literature. However, there were no significant differences between EBVaGC and EBV negative gastric cancers. This suggests that the role of EBV in gastric cancer may be mostly incidental rather than any causal relation. However, further studies are required.

  • Background: An independent medical examination (IME) is a critical process for awarding reparation for injury. However, conducting an IME in pain medicine is very difficult, not only because pain is a subjective symptom, but also because there are no proper objective methods to demonstrate it. This study was conducted to compare IME reports and the court decisions on the disability status of the patients. Methods: We analyzed 79 IME reports and 25 corresponding court decisions on the disability status of patients. The diagnoses, causal relationships between the patients' status and the trauma, McBride's degree of disability, the American Medical Association's impairment ratings, the estimated annual cost for future treatment, and the necessity of care-giving were compared and analyzed. Results: The diagnoses in the 79 cases were complex regional pain syndrome (CRPS) type I (58 cases), CRPS type II (7 cases), peripheral neuropathy (5 cases), myofascial pain syndrome (4 cases), herniated intervertebral disc (2 cases), and fibromyalgia (1 case). The types of accidents were road traffic accidents (50 cases), military injuries (14 cases), industrial accidents (11 cases), and others (4 cases). The IME reports and the court decisions stated considerably different McBride's degrees of disability (P = 0.014). However, there was no significant difference in the estimated cost for future treatment between the IME reports and the court decisions (P = 0.912). Conclusions: IME reports should be accurate, fair, and based on objective findings. Feedback on IMEs from the court decisions is helpful for reference use.

  • 본 연구는 1980~2009년 동안 한국의 경제성장과 총 전력소비 및 산업별 전력소비 사이의 인과관계를 분석하였다. 이를 위해 단위근 검정을 실시하였으며 그 결과, 실질 GDP, 제1차 산업, 제조업 그리고 총 전력소비는 1차 차분형태의 안정적인 변수로 나타났다. 그러나 서비스업 전력소비는 2차 차분을 실시했을 때에 안정적인 변수로 나타났다. 공적분 검정을 실시한 결과, 실질 GDP와 총 전력소비 및 산업별 전력소비 사이에는 장기균형 관계가 존재하지 않는 것으로 분석되었다. 따라서 표준 Granger 인과관계 검정에 의하면, 경제성장이 총 전력소비, 제1차 산업 및 제조업의 전력소비에 영향을 주는 일방향 인과관계가 존재하는 것으로 나타났다. 그러나 서비스업 전력소비는 경제성장과 아무런 인과관계를 발견할 수 없었다. 이러한 인과성은 전력부문의 가격 및 비가격정책 등이 경제성장에 부정적인 영향을 최소화하면서 실행될 수 있음을 의미한다.

  • This study investigated the causal relationships among the elderly, looking at social participation, depression, self-reported health, and life satisfaction. It was especially focused on the mediating effects of depression and self-reported health on the relationship between social participation and life satisfaction. From the 2006 Korean Longitudinal Study of Aging, data for 4,155 elderly over age 65 was analyzed with structural equations modeling with Amos 7.0 and sobel test. Major findings were as follows. First, social participation of the elderly has a negative influence on depression and a positive influence on self-reported health and life satisfaction. Second, self-reported health has a partial mediating effect on the relationship between social participation and life satisfaction. Third, the direct effect of depression on life satisfaction was not statistically significant, while the direct effect of social participation was significant. Therefore, depression was not proved as a significant mediator. This study tested the effects of social participation on depression, self-reported health, and life satisfaction empirically and confirmed the partial mediating model, in which social participation improves the elderly's self-reported health, which in turn improves the elderly's life satisfaction. These results suggest the importance of an integrated approach for the healthy and successful aging and the diverse types of social participation in an elderly person's quality of life.

  • Purpose - With the economic development in China, the lifestyle of Chinese customers has changed dramatically. Chinese customers are more likely to have coffee in a shop with the ability to make them happy than those with high quality coffee in a nice physical environment. Happiness becomes a critical driver of customers' intention to purchase a cup of coffee in a specific coffee shop again and again. As a result, happiness becomes an important factor for managers to make strategies for attracting customers. Although managers and scholars pay more attention to emphasize the importance of happiness in customers' consumption, little research has been conducted to investigate the relationship between happiness and coffee shop's continuous usage intention in the Chinese coffee industry. Research design, data, and methodology - A research model is made to explain the impact of happiness on customer's behavior. To understand the influence of happiness better, we consider two dimensions of happiness which are subjective well-being and psychological well-being. In order to confirm the relationships of the variables in the research model, the online survey is constructed in China. Customers who have experienced the services in a coffee shop are asked to do the questionnaire. With 453 reliable questionnaires, structural equation modeling is used to analyze the causal relationships of the coffee quality, physical environment, subjective well-being, psychological well-being, and continuous usage intention. Results - Results indicate that coffee quality and physical environment are not the direct factors that influence customers' continuous usage intention. However, good coffee quality and physical environment are the significant predictors of Chinese customers' happiness associated with subjective well-being and psychological well-being, which in turn affects customers' continuous usage intention. Conclusions - In this study, it is proposed that coffee quality and physical environment may be the key factors influencing customers' happiness. Happiness, including subjective well-being and psychological well-being matters in decision making process. More importantly, happiness increases the continuous usage intention when the coffee shop can serve customers with higher quality coffee at a good atmospheric place. Managers should consider happiness as an important factor in making marketing strategies to compete in this industry.

  • Capitalism is based on a material desire of the human being. the social control of capital value and the management of capital ability reflects the actual condition of the capitalism well. The unconstrained growing and the expansion of capitalism, it finally lost social meaning and an importance of human being element and the safety of the civilian life, began to threat the security of citizen by forming over the material center structure of society. Improving human life quality and material richness on their life leads positive factor of capitalism whereas is causing several crimes through the society which is being threatened around a human being life for a negative factor of the capitalism. Therefore capitalistic social system has offered both a positive factor 'growing' and 'richness' and that of a negative 'structural poverty' and 'lack of security' and they have been remaining the assignment of capitalism 'poverty' and 'security' by settlement in the society for a extremely phenomenon of both sides. The objective of this research is to build its study theory and establish its causal relation by illuminating for the social environment of capitalism for a private guard or a development background of the civil security contributing for citizen security, as well as gets the clue of the development possibility of the civil guard and escort field and the development of capitalism. In Korea because their recognition of the study approach and the social safety for social security control function is still staying first step and our daily life is annoying from various threat of the society, many studies and the realistic necessity of experience related with social security is being studied. In addition, The development possibility of the civil guard and defense at the civil field which will be keep the social security has a wide position but its study approach and realistic comprehension is still in insufficient condition. Consequently, this research is started to grasp the security of civil fiend and to grope a development possibility through the research of capitalism.

  • 지금까지 사이버보안에 대한 부분적인 연구는 많이 시도되었으나, 기업 내부적인 요인과 외부 요인의 관계를 총체적으로 분석한 연구는 국내뿐만 아니라 국외에서도 거의 없었다. 따라서, 본 연구에서는 중소기업의 내부 요소 뿐 아니라 기업경영 환경을 고려한 사이버보안 관리에 대하여 살펴보았다. 혼합적 연구방법론을 통하여 1차 질적 분석, 2차 양적 분석을 실시하였다. 질적 분석은 반구조적 인터뷰 방식을 통해 진행하였고 사이버보안 관리체계의 미비, 사이버보안에 대한 내부적인 비협조, 의사결정체계에 파생되는 문제점이라는 세 가지 주제를 발견하였다. 양적 분석은 설문 조사를 통해 확보한 데이터를 대상으로 다중회귀분석을 실시하였으며, 독립변수 중에 사이버위협에 대한 인식과 내부적인 지지가 종속변수인 사이버보안 관리체계에 (+)의 방향으로 영향을 미치며 통계적으로 유의미한 것으로 나타났다. 이 연구를 통해 중소기업의 사이버보안에 있어서는 외부적 환경 변수보다는 내부적인 변수가 사이버보안 관리체계에 인과적 영향이 있었으며, 이는 직원들의 인식 등 조직 문화와 관련되는 변수가 중요하다는 것을 말해준다. 이러한 결과는 중소기업에서 사이버보안 관리체계를 높이는데 실질적인 의의를 제공해 줄 것으로 기대된다.

  • Among the causes of childhood behavioral problems - that is, physiological, psychological, and environmental factors -, the common element of non-organic psychological and environmental factors is influences from the parents. Roles of mother who does the biggest emotional exchange with the child after birth may have substantial association with the childhood behavioral problems. In this connection, the present explanatory study was conducted for the purpose of understanding the causal structural relationship in which mother's child caring behaviors affect child behavioral problems. The data collection period was July 2 - 7, 2001. The subject was 4th, 5th, 6th graders' mothers in 4 elementary schools located in Daejoen city and 299 surveys were used in the analysis. As for the tools used in this study to assess the mother's child caring Behavior Scale by Park, Seong-Yeon and Yi, Sook (1990) was used to measure the mother's behaviors. The child behavioral problems were measured with the Korean-Child Behavior Checklist (K-CBCL), standardized into the Korean version by O, Gyung-Ja, Yi, Hye-Ryon, Hong, Gang-Eui, and Ha, Eun-Hye. For the data processing, the frequency and the percentage were calculated, and the analyses of variance, correlation were carried out. The result of this study is summarized as follows: First, the examination of the effect of mother's general characteristics on the mother's caring behavior shows that significant differences are made by the active participation (p=0.020) in the occupation, affection(p=0.000), authority control(p=0.013), achievement(p=0.030), active participation(p=0.032) in the education level, consistency regulation(p=0.007) in the religion. Second, the examination of the effect of mother's caring behaviors on the child behavioral problems shows that significant differences are made by some child behavioral problems in the affection, achievement, consistency regulation, authority control, over protection caring behaviors. Third, as for the correlation between mother's child caring behavior and child behavioral problems, a significant correlation is revealed between the negative child caring behavior and child behavioral problems.
