Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

Ho-Chang Lee1, Seung-Myoung Son, Yong-Moon Lee, Ji Hae Koo, Song-Yi Choi, Ok-Jun Lee, Eun-Hwan Jeong 충북대학교 동물의학연구소 2012 Journal of Biomedical and Translational Research Vol.13 No.2

Malignant transformation of mature cystic teratoma (MCT) is rare. Sarcomatoid carcinoma is a neoplasm comprising malignant mesenchymal cells and a conventional carcinomatous area. Here, we report on a case of sarcomatoid carcinoma arising from an MCT in the left ovary of a 45-year-old female. A unilocular cyst consistent with MCT was observed; however, a nodule within the cyst was confirmed from the resected ovary. Microscopically, the nodule showed both squamous cell carcinoma and pleomorphic sarcomatous components admixing with each other. Lining epithelial cells at the periphery of the main tumor showed squamous metaplasia. When a sarcomatous component is observed in the ovary tumor, it is important to find a squamous cell component, either benign or malignant.

브랜드 동일시, 브랜드 감정, 브랜드 로열티의 관계에 관한 연구 : 실용적 제품과 쾌락적 제품간의 비교

이유재,이지영 한국방송광고공사 2004 광고연구 Vol.0 No.65

본 연구에서는 브랜드 동일시(brand identification)가 브랜드 로열티에 어떠한 영향을 미치는지를 심층적으로 살펴보았다. 우선 브랜드 로열티를 행동적 로열티와 태도적 로열티로 구분하여 살펴보았으며, 브랜드 감정(brand affect)이라는 개념을 도입하여 브랜드 동일시와 브랜드 로열티의 관계에서 브랜드 감정의 매개역할을 살펴보았다. 특히 제품유형을 쾌락적 제품(hedonic product)과 실용적 제품(utilitarian product)으로 나누어 브랜드 동일시, 브랜드 감정, 브랜드 로열티간의 관계가 제품유형에 따라 어떻게 달라지는가를 살펴보았다. 본 연구 결과, 브랜드 동일시가 증가할수록 브랜드에 대한 태도적 로열티와 행동적 로열티가 모두 증가하며, 브랜드 동일시는 브랜드 감정에 긍정적 영향을 미칠 수 있음을 확인하였다. 한편, 브랜드 로열티를 형성하는 과정에서 매개변수의 역할을 하는 브랜드 감정은 브랜드 로열티에 긍정적 영향을 미칠 수 있음을 확인하였다. 또한, 브랜드 동일시가 태도적 로열티에 미치는 영향력은 실용적 제품보다 쾌락적 제품에서 더 크게 나타났으며, 브랜드 동일시가 행동적 로열티에 미치는 영향력 역시 쾌락적 제품에서 더 크게 나타났다. This study investigates the influence of brand-self identification on brand loyalty by employing the concept of brand affect. This study especially focuses on the meæflating role of brand affect between brand identification and brand loyalty. This study also examines the differential influence of brand identification on brand loyalty between the two product classes: hedonic products and utilitarian products. Several interesting results are found. First, brand identification has a positive influence on brand loyalty; that is, as brand identification increases, both attitudinal and behavioral loyalty increase. Second, brand identification can have a positive influence on brand affect; consumers may feel pleased when they purchase the brand that gives high brand-self identification. Third, brand affect can have a positive influence on brand loyalty. Fourth, the influence of brand identification on both attitudinal loyalty and behavioral loyalty is greater for hedonic products than for utilitarian products.

Background and Objectives : Several speech manifestation are observed in temporal lobe epilepsy(TLE). We studied the frequency of ictal speech manifestations and their localizing and lateralizing value in TLE. Methods : We reviewed 379 seizures recorded on videotape in 135 patients who underwent temporal lobectomy for intractable TLE. We divided patients into group A(n=75) who became seizures free after surgery, and group B(n=60) who were only slightly benefited or unchanged after surgery. Speech manifestations were classified as normal speech, vocalization, or abnormal speech. Abnormal speech was subdivided into speech arrest, dysarthria, dysphasia, or nonidentifiable speech. Results : Speech manifestations occurred in 70(18.5%) seizures of 28 patients. Forty eight seizures of 20 patients were observed in group A, and 22 seizures of 8 patients were observed in group B. In group A, 25 seizures of 11 patients were originating from dominant hemisphere, 23 seizures of 9 patients from nondominant hemisphere. In group B, 13 seizures of 5 patients were originating from dominant hemisphere, and 9 seizures in Lt. side and 6 seizures in Rt. side, respectively) of group A(P>0.05), and eleven seizures of 4 patients(8 seizures from Lt. side and 3 seizure from Rt. side) in group B(P>0.05). Normal speech was observed only seizures from Rt. side in both groups(3 seizures in 1 patient, each group). Dysphasia occurred only in seizures originating from Lt. side. Nonidentifiable speech occurred in 22 seizures of 9 patients(11 seizures from each side) in group A(P<0.01), and 3 seizures of 1 patient occurred only from Lt. side in group B. Conclusion : Ictal speech manifestations were not uncommon(18.5%). All kinds of ictal speech manifestations except normal speech have no reliable lateralizing and localizing value in TLE. Normal speech could be a good indicator of seizure originating from nondominant hemisphere.

In this study, the spatiotemporal surface temperature changes were analyzed in the Korean pennisula. The surface temperature variation was estimated using the split-window method and NOAA/AVHRR data in 1991, 1995 and 2000. The ranges of differences were 3-15℃ around the penninsula. The differences in seasonal variations and yearly flucturations in big cities were lower than those in rural areas and showed clearly the effects of the urbanization. The characteristics of urban heat affects were further determined based on the day and night time temparature comparision on Busan metropolitan area between these periods. Finally, the future use of this technology was suggested for the urban environmental planning.

이지훈,육완이,양호연,하종현 대한방사선 방어학회 2002 방사선방어학회지 Vol.27 No.2

원자력발전소에서 주로 발생되는 금속폐기물인 탄소강을 중성염전해질인 1.7M의 황산나트륨(Na₂SO₄)과 질산나트륨(NaNO₃)을 이용하여 기존전해제염과 개선된 전해제염공정의 비교실험을 수행하였다. 양극은 인코넬, 음극은 티타늄으로 하여 상온에서 1시간동안 반응시켜 금속폐기물 모재의 weight loss, 두께변화, 전해질 내 침전물농도, SEM을 이용하여 제염전후의 금속폐기물 표면의 형상을 분석하였다. 실험결과 개선된 전해제염 적용시 전해질 종류별 전류밀도 변화에 따른 실험에서는 전류밀도가 0.1∼0.6A/cm²으로 증가함에 따라 1.7M의 황산나트륨 적용시 금속폐기물 모재의 두께변화는 0.48±0.005∼67.7±0.02um, 1.7M의 질산나트륨 적용시에는 0.06±0.005∼17.7±0.05로 나타나 같은 전류밀도에서 황산나트륨 적용시 금속폐기물 모재의 표면 제염효율이 더욱 높은 양상을 보였다. 또한 전류밀도 0.3 A/cm² 및 1.7M의 황산나트륨의 조건에서 개선된 전해제염 적용 시 9.8±0.01um의 금속폐기물 두께변화를 보여 기존전해제염 적용시인 3.7±0.03um의 금속폐기물 두께변화보다 2배 이상의 표면 제염효과를 보였다. Conventional and modified electrolytic decontamination experiment were performed in the 1.7 M solution of sodium sulfate and sodium nitrate for decontamination of carbon steel as the simulated metal wastes which have been produced in large amounts from nuclear power plants. Anode and cathode were used as inconel and titanium respectively. The reaction time and temperature were 1 hr and 25℃. The analyses were performed of the characteristics such as weight loss and thickness change of metal waste, suspended solid in electrolyte and SEM observation. In modified electrolyte decontamination system with increased current density ranged from 0.1 to 0.6 A/cm², the metal waste showed thickness changes of 0.48±0.005 to 67.7±0.02um in 1.7 M sodium sulfate and those of 0.06±0.005 to 17.7±0.05um in sodium nitrate. Metal waste in modified electrolyte decontamination system showed the thickness change of 9.8±0.01um while it reacted up to 3.7±0.03um in conventional system with 0.3 A/cm² of current density and 1.7 M sodium sulfate. Decontamination efficiencies of modified electrolytic process are much higher than that of conventional electrolytic process when both are applied to metal waste.

이주영,박지혜,김송이,이주희,한용문 동덕여자대학교 종합약학연구소 2006 동덕약학연구지 Vol.10 No.-

In this study, we determined proliferate effect on T-lymphocytes and antifungal activity of glycyrol that was isolated from Glycyrrhizae Radix (Leguminosae). In addition, immunoadjuvant activity of glycyrol was determined. Results showed that Gylcyrol (GCR) suppressed the proliferation of murine splenocytes that were treated with Concanavalin A (Con A). In case of the immunoadjuvant effect, glycyrol had no enhancement on antibody production. Data from experiments of antifungal activity in vitro, the component resulted in inhibition of Candida albicans growth. The antifungal effect appeared to be more potent than fluconazole. These data indicate that Glycyrol has no specific immunological effect on T- and B-cells, but the component contains antifungal activity.

활동이론의 관점에서 바라본 박물관, 커뮤니케이션, 그리고 학습

박지연,이수민,이병준 한국문화교육학회 2011 문화예술교육연구 Vol.6 No.4

Museum is a medium which communicates with previous generation's experiential memories and present generation's cultural memories. Therefore, the communication is a core task in museum. Museum needs mediums like exhibition and education and we have to discuss how to structuralize these things. The museum communication could be explained through the Cultural-Historical Activity Theory(CHAT). The CHAT has been developed by several theorists like Vygotsky. Especially, the third generation's CHAT has been developing by Engeström. It is a worthy theoretical structure that can show museum as a messenger of communication in society and its communication problems. This study is based on the CHAT and analyzes museum in a social activity system and activity system in a museum from micro/macro-scopic view. Also, it produces practical models that connect museum with community art field and museum with schools. 박물관은 앞선 세대의 체험적 기억을 현 세대에게 문화적 기억의 형태로 커뮤니케이션하는 매개체이다. 따라서 박물관에서 소통(communication)이라는 개념은 핵심적인 과제일수 밖에 없다. 박물관은 그 자체로 전시와 교육과 같은 매체(medium)를 필요로 하며 이를 어떻게 구조화할 것인가의 문제가 박물관커뮤니케이션의 측면에서 논의될 필요가 있다. 이러한 거시적, 미시적 차원의 박물관커뮤니케이션의 과제는 비고츠키와 여러 이론가들의 연구성과를 정리하고 발전시킨 활동이론에 의해 잘 설명될 수 있을 것으로 보인다. 특히 Y. Engeström에 의해 발전된 제3세대 활동이론은 사회속에서의 커뮤니케이션의 전달자로서의 박물관과 박물관내에서의 커뮤니케이션의 문제를 잘 드러낼 수 있는 이론체계라고 생각된다. 본 연구는 활동이론에 근거하여 거시적·미시적 관점에서 사회활동시스템 속에서의 박물관과 박물관 내에서의 활동시스템을 분석하고 이를 통해 박물관의 커뮤니케이션을 박물관 내부 활동시스템 간의 네트워크 실천, 박물관과 지역의 예술장(藝術場)이 연계된 네트워크 실천과 박물관과 학교가 연계된 네트워크 실천 모형을 구조화하여 제시하려 한다.

연구목적 : 본 연구의 목적은 임상가를 위한 외상후 스트레스 장애 척도의 신뢰도와 타당도를 알아보고자 하는 것이다. 방 법 : 28명의 PTSD 군, 30명의 Non-PTSD군, 36명의 정상군에 대하여 임상가를 위한 외상후 스트레스 장애 척도를 실시하였다. 면담자간 신뢰도를 평가하기 위하여 10명의 외상후 스트레스 장애 환자를 2명의 검사자가 동시에 평가하였다. 타당도를 평가하기 위하여 모든 피검자들을 대상으로 사건 충격 척도, Beck의 우울 검사, Spielberger의 상태 특성 불안 검사 Ⅰ, Ⅱ를 시행하였다. 결 과 : Cronbach's α와 면담자간 일치도는 각각 .95와 .89였다. 임상가를 위한 외상후 스트레스 장애 척도는 각각 사건 충격 척도(r=.80), Beck의 우울 검사(r=.70), Spielberger의 상태 특성 불안 검사 Ⅱ(r=.56)와 높은 상관을 가지고 있었다. 그러나 Spielberger의 상태 특성 불안 검사 Ⅰ(r=.20)과는 상관을 보이지 않았다. 임상가를 위한 외상후 스트레스 장애 척도는 임상 진단과 82.1%의 일치도를 보였다. 결 론 : 임상가를 위한 외상후 스트레스 장애 척도는 충분한 신뢰도와 타당도를 가지고 있었다. 임상가를 위한 외상후 스트레스 장애 척도는 외상후 스트레스 장애를 진단하기에 유용한 도구라 할 수 있다. Objectives : The purpose of this study was to examine the reliability and validity of A Clinician-Administered PTSD Scale (CAPS). Methods : CAPS was administered to 28 PTSD subjects, 30 non-PTSD subjects, and 36 normal subjects, Interrater reliability for the CAPS was established by interviewing 10 PTSD subjects. The interviews were conducted by 2 interviewers simultaneously. The authors administered to all the subjects Impact of Event Scale(IES), Beck Depression Inventory(BDI), State Trait Anxiety InventoryⅠ, Ⅱ(STAI-I, Ⅱ) for measuring concurrent validity. Results : The value of Cronbach's α and interrater agreement were .95 and .89, respectively. The CAPS was highly correlated with IES(r=.80), BDI(r=.70), STAI-Ⅱ(r=.56). But the CAPS was not correlated with STAI-I(r=.20). The CAPS showed an overall agreement with clinical diagnosis of 82.1%. Conclusions : The CAPS shows a reasonable degree of reliability and validity. The CAPS could be a valuable tool to diagnose PTSD.
