목적: 전 세계적으로 매년 신규 HIV 감염의 발생은 서서히 감소하는 추세를 보이고 있다. 그러나 국내 신규 HIV 감염의 발생은 도리어 급격히 증가하는 양상을 보이고 있으며, 젊은 층에서의 급격한 증가가 원인으로 알려졌다. 이에 국내에서 HIV 감염의 감염 경로를 분석하고 규명함은 국내에서의 급격한 증가 원인을 밝히고, 그에 대한 예방 및 관리 대책을 수립함에 있어서 중요한 근거가 되겠다. 방법: 2006년 12월부터 2018년 1월 까지 ‘한국 HIV/AIDS 코호트’에 등록된 HIV 감염인을 조사하여 분석하였다. 전국21개 참여 병원에서 진료를 받고 있는 18세 이상의 HIV 감염인으로서 등록 시에 주치의의 역학 관련 문진에 이어 훈련된 전문 상담 간호사가 제시하는 표준화된 설문지를 통해서 역학 조사를 실시하였다. 수집된 자료를 분석하여 전체 대상 및 연령군에 따른 감염 경로를 규명하였고, 특히 젊은 층에서는 좀 더 세부적으로 연령을 구분하여 감염 경로를 조사하고 비교하였다. 결과: 조사 대상은 1,474명이었으며, 남자는 1,377명, 여자는 97명이었다. 조사 대상의 평균 연령값은 41.4 ± 12.6세였으며, 남녀 성비는 14.2:1이었다. 전체 대상 HIV 감염인의 감염 경로를 분석해 보면 동성 및 양성 간 성접촉이 886명 (60.1%), 이성 간 성접촉이 508명(34.6%), 수혈 및 혈액제제에 의한 감염이 5명(0.3%), 마약주사 공동사용에 의한 감염이 1명(0.0%)이었다. 연령군에 따른 감염 경로를 비교해 보면 젊은 연령군으로 갈수록 동성 및 양성 간 성접촉에 의한 비율이 증가하였다. 다시 말해서, 18-29세의 젊은 연령군에 있어서는 동성 및 양성 간 성접촉이 71.5%로 크게 증가하였다. 또한, 18-29세의 젊은 연령군을 좀 더 세분화해서 조사해보면 젊을수록 동성 및 양성 간 성접촉에 의한 감염이 크게 증가하여 18-19세의 10대에서는 92.9%가 동성 및 양성 간 성접촉에 의해서 감염되었다. 결론: 국내 HIV 감염의 가장 주된 감염 경로는 동성 및 양성 간 성접촉이며, 이러한 경향은 연령이 젊어질수록 더욱 뚜렷이 나타났다. 특히, 10대의 경우에는 대부분이 동성 및 양성 간 성접촉에 의하여 감염되었다. 따라서 그에 따른 합리적인 예방 및 관리 정책을 수립하는 것이 절실히 요구된다 하겠다. Background/Aims: Global efforts to prevent human immunodeficiency virus (HIV) infection and strengthen treatment programs have reduced the annual incidence of HIV infection. However, the incidence recently increased unexpectedly in Korea. Therefore, to understand the cause of the increase in HIV infection incidence in Korea, it is important to identify the mode of HIV transmission. Methods: We included HIV-infected individuals enrolled in the Korea HIV/AIDS (acquired immune deficiency syndrome) Cohort from December 2006 to January 2018. The subjects were older than 18 years and were receiving care at 21 participating hospitals. They were interviewed by their physician at enrollment, and an epidemiological survey was conducted using a stand ardized questionnaire provided by a professional counseling nurse. Results: There were 1,474 subjects: 1,377 men and 97 women. Their mean age was 41.4 ± 12.6 years, and the male-to-female ratio was 14.2. The transmission modes were as follows: homosexual and bisexual contacts in 885 (60.1%), heterosexual contacts in 508 (34.6%), blood transfusion and blood products in 5 (0.3%), and injected drug use in 1 (0.0%). Regarding age, the proportion infected by homosexual and bisexual contacts was higher in the younger age groups: 71.5% in subjects aged 18-29 years. When this age group was further subdivided, 92.9% of those aged 18-19 years were determined to be infected via homosexual and bisexual contacts. Conclusions: In Korea, HIV is transmitted predominantly via homosexual and bisexual contacts, which is more common among younger age groups and the cause of infections in most teenagers.

Epidural abscess in hemodialysis patient is uncommon diseases, but it causes severe neruological complication if diagnois is delayed. In the clinical practice, because it is difficult to differentiate epidural abscess with simple back pain. Therefore, it is important to make early diagnosis and treatment of epidural abscess to prevent nuurological sequellae. We here report a case of epidural abscess with early diagnosis and successful treatment. A 54-year-old male patient was admitted to back pain and fever. Under the presumptive diagnosis of epidural abscess, MRI was perofrmed, and it revealed epidural abscess. Intravenous antibiotic treatment was started and drain of abscess was subsequently performed since back pain was persisted. He discharged without neurologic sequellae. Our case strongly suggests that epidural abscess should be considered in patients and early radiologic evaluation and treatment are mandatory to prevent neurological complication.

With the pervasiveness of digital environment and expansion of new media, ICT (Information and Communication Technology) leads the role of consumer to change from a passive customer into an active co-producer. As customer participation in the fashion industry increases, this study attempts to explore the cases of customer participation as a co-producer in fashion industry through analyzing business models of companies, including Threadless, Blank label, Cut on Your Bias, Acustom Apparel, Thinkgivers. The results show that customer participation is mainly facilitated through design participation in fashion industry, with different level of participation and IT as well as different contribution target. Compared to the past, consumer`s preference is reflected through participation before the stage of production. Results indicate three main characteristics of customer participation in fashion industry. First, value co-creations using customer experiences and understanding customer needs are important. Second, active online communication among customers are critical. Third, it is important to ensure customer`s own item. From a customer perspective, participation enables them to purchase their own distinctive product and offers exciting experience and satisfaction over the production processes, and compensation can be used to increase customer participation. On the other hand, companies using customer participation can take advantage of cost reduction in product development, inventory, and marketing. Customer participation, as a win-win strategy for business and consumer, is expected to expand further in the future with the development of ICT.

  본 연구는 점포를 방문하는 동안 노출되는 매장의 물리적 환경 특성이 서비스 브랜드 개성과 재구매 의도에 미치는 영향력을 규명하기 위해 시도되었다. 이를 위해 연구모형을 개발하여, 특정 서비스 브랜드의 이용객을 대상으로 설문조사를 실시하고 구조방정식을 이용하여 분석하였다.<BR>  연구 결과는 우선, 서비스의 물리적 환경은 주변요인, 디자인요인, 사회요인으로, 그리고 서비스브랜드 개성은 유능함, 성실함, 흥분됨, 세련됨, 강인함 차원으로 분류되었다. 둘째, 물리적 환경의 모든 차원들이 모든 서비스 브랜드 개성차원에 정(+)의 영향을 주었으며, 물리적 환경의 서비스 브랜드 개성에 대한 영향력은 각 차원별로 상이하였다. 셋째, 서비스 브랜드 개성은 모두 재구매의도에 정(+)의 영향을 주었으며, 특히 세련됨 차원에 미치는 영항이 가장 켰다. 넷째, 서비스의 물리적 환경은 재구매의도에 정(+)의 영향을 주었으며, 특히 물리적 환경 중 사회요인이 재구매의도에 가장 큰 영향을 주는 것으로 나타났다. 이와 같은 결과들은 물리적 환경 연출은 브랜드 개성 형성의 결정요인으로 서비스 브랜드 차별화의 핵심요인으로 작용하므로, 호의적인 브랜드 개성 창출을 위해서는 우선적으로 물리적 환경에 대한 효율적 관리 방안이 강구되어야 함을 보여준다.   The study examines how the environmental factors of store influence service brand personality and repurchase intention in the service environment. The service industry has been experiencing the intensified competition with the industry’s continuous growth and the influence from rapid technological advancement. Under the circumstances, it has become ever more important for the brand competitiveness to be distinctively recognized against competition. A brand needs to be distinguished and differentiated from competing companies because they are all engaged in the similar environment of the service industry. The differentiation of brand achievement has become increasingly important to highlight certain brand functions to include emotional, self-expressive, and symbolic functions since the importance of such functions has been further emphasized in promoting consumption activities.<BR>  That is the recent role of brand personality that has been emphasized in the service industry. In other words, customers now freely and actively express their personalities or egos in consumption activities, taking an important role in construction of a brand asset. Hence, the study suggests that it is necessary to disperse the recognition and acknowledgement that the maintenance of the existing customers contributes more to boost repurchase intention when it is compared to the efforts to create new customers, particularly in the service industry.<BR>  Meanwhile, the store itself can offer a unique environment that may influence the consumer’s purchase decision. Consumers interact with store environments in the process of virtually, all household purchase they make (Sarel 1981). Thus, store environments may encourage customers to purchase. The roles that store environments play are to provide informational cues to customers about the store and goods and communicate messages to stimulate consumers" emotions. The store environments differentiate the store from competing stores and build a unique service brand personality.<BR>  However, the existing studies related to brand in the service industry mostly concentrated on the relationship between the quality of service and customer satisfaction, and they are mostly generalized while the connective studies focused on brand personality. Such approaches show limitations and are insufficient to investigate on the relationship between store environment and brand personality in the service industry.<BR>  Accordingly, the study intends to identify the level of contribution to the establishment of brand personality made by the store’s physical environments that influence on the specific brand characteristics depending on the type of service. The study also intends to identify what kind of relationships with brand personality exists with brand personality while being influenced by store environments. In addition, the study intends to make meaningful suggestions to better direct marketing efforts by identifying whether a brand personality makes a positive influence to induce an intention for repurchase.<BR>  For this study, the service industry is classified into four categories based on to the characteristics of service: experimental-emotional service, emotional -credible service, credible-functional service, and functional-experimental service. The type of business with the most frequent customer contact is determined for each service type and the enterprise with the highest brand value in each service sector based on the report made by the Korea Management Association. They are designated as the representative of each category. The selected representatives are a fast-food store (experimental-emotional service), a cinema house (emotional-credible service), a bank (credible-functional service), and discount store (functional-experimental service).<BR>  The survey was conducted for the four selected brands to represent each s

Mantle cell lymphoma (MCL) is an uncommon type of gastrointestinal lymphoma. MCL is a distinct subtype of B-cell non-Hodgkin lymphomas. The major subtype of MCL is characterized by the presence of multiple lymphomatous polyposis (MLP), in which multiple polyps are observed along the gastrointestinal tract. The malignant cells express pan B-cell marker and the T-cell marker cluster of differentiation 5. The chromosomal translocation t(11;14)(q13;q32) that causes cyclin D1 overexpression is commonly observed on the cytogenetic analysis of MCL. Survival improvement has recently been achieved for patient with MCL by the successful introduction of monoclonal antibodies and dose-intensified approaches for treatment, including autologous stem cell transplantation strategies. Some reports suggest that there is an increased incidence of second malignancies in patients with MCL or lymphoma. We report a case of MCL involving the colon; the patient was a 60-year-old man who complained of low abdominal discomfort during defecation. During the workup, a meningioma was unexpectedly discovered. On analysis, the tumor was found to be a t(11;14)-negative and non-MLP-type MCL. (Korean J Gastroenterol 2012;60:56-60)
