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.

Euna Jung,Meehyun Lim,Youngwoong Do,Soonsung Lee,Hyuck Jae Choi,한해욱,Kyoung-Sik Cho,Kyu-Rae Kim 한국광학회 2011 Current Optics and Photonics Vol.15 No.2

Lymph node metastasis is an important prognostic factor in cervical cancer patients. We report THz imaging for detecting micro-metastatic foci in the lymph nodes of early-stage uterine cervical cancer patients. Five paraffin-embedded metastatic lymph nodes from two cervical cancer patients were imaged using a THz time-domain spectroscopy system in the reflection mode. The size and shape of the tumor regions were compared with those from histopathologic examinations. The metastatic portions of lymph nodes as small as 3 mm were well delineated by THz imaging. The reflected peak amplitudes were lower in metastatic portions than in the normal portions of lymph nodes, and the difference in their peak-to-peak amplitudes was ~5%.

Y 제올라이트로부터 합성한 메조 포러스 물질을 지지체로 사용한 백금 촉매를 n-octadecane의 수첨업그레이딩 반응을 통한 항공유 제조에 적용 하였다. Y 제올라이트를 골격 구성물질로 사용하여 메조 포러스 알루미노실리케이트(MMZHY)를 합성 하였다. Pt/MMZHY 촉매상에서 Mg 첨가가 n-octadecane의 수첨업그레이딩 반응에 미치는 영향을 고찰 하였다. 촉매의 특성은 X 선 회절, 질소 흡착, 승온환원, 암모니아승온탈착 및 흡착 피리딘 적외선 분광법으로 수행 하였다. 본연구에서 Mg가 2 wt% 첨가된 Pt/MMZHY 촉매가 가장 높은 항공유 수율을 보였는데, 이는 Mg의 첨가에 의해 Pt금속의 분산도와 환원도가 증가할 뿐만 아니라, 산점의 양과 세기가 증가하기 때문이다. 또한 PtMg/MMZHY 촉매 상에서 이소 파라핀에 대한 선택도가 80 % 이상임을 확인하였다. Platinum catalysts supported on the mesoporous material synthesized from Y zeolite were applied to synthesis of jet-fuel through n-octadecane hydroupgrading. The mesoporous aluminosolicate, MMZHY was synthesized using Y zeolite as its framework source. The effect of the addition of Mg to Pt/MMZHY catalyst for n octadecane hydroupgrading was investigated. Catalyst characterization was performed with X-ray diffraction, N2 adsorption, temperature-programmed reduction in hydrogen flow, temperature-programmed desorption of ammonia, and infrared spectroscopy of adsorbed pyridine. The high yield of jet-fuel over the PtMg(2.0)/MMZHY can be attributed not only to the higher dispersion of Pt metal and higher reducibility, but also the higher amount of acid sites and higher strength of acid sites. The selectivity to iso-paraffin in the jet-fuel fraction could be reached above 80% over the optimized PtMg/MMZHY catalyst.

정은아(Jung, Euna),김정희(Kim, JungHee) 한국물류학회 2020 물류학회지 Vol.30 No.2

본 연구는 기업들이 혁신적인 상거래 서비스를 제공하고 고객만족을 실현하기 위해 조성한 통합유통채널 상황에서, 마케팅 성 과를 향상하기 위한 방안을 모색하기 위해, 소비자가 경험한 피로감, 성가심, 즐거움의 부정적인 요소와 긍정적인 요인들을 동시 에 고려하여, 이들 개념들이 저항 및 재구매의도에 미치는 영향과 이들 개념들간의 구조적관계를 분석하고자 하였다. 이를 위해 선행연구를 중심으로 연구개념들간의 관계 등을 고찰하여 가설설정 및 연구모형을 개발하고, 설문조사에 의해 이를 검증하였다. 연구결과는 다음과 같이 요약된다. 첫째, 통합유통채널 사용 상황에서 소비자는 피로감과 성가심을 경험하며, 이는 즐거움에 부 (-)의 유의미한 영향을 미친다. 둘째, 통합유통채널 사용 상황에서 소비자가 지각한 성가심은 저항에 유의미한 정 (+)의 영향을 미 친다. 셋째, 통합유통채널 사용 상황에서 사용자가 지각한 즐거움은 사용자 저항에는 유의미한 부 (-)의 영향을, 재구매의도에는 유의미한 정 (+)의 영향을 주었다. 이와 같은 결과는 통합유통채널 상황에서 사용자가 지각한 피로감과 성가심은 즐거움을 억제하 고 저항을 불러올 수 있는 원인이 될 수 있으나, 즐거움은 저항을 완화 혹은 제거하거나 재구매의도를 유발하는 중요한 역할을 한다는 것을 시사한다. This study aims to find ways to improve marketing performance in the context of integrated distribution channels created by companies to provide innovative commerce services and realize customer satisfaction. By considering the negative and positive factors of pleasure at the same time, This paper tried to analyze the impact of these concepts on resistance and repurchase intention and the structural relationship between these concepts. To this end, the relationship between research concepts was considered, focusing on prior research, and hypothesis setting and research model were developed and verified by questionnaire survey. The research results are summarized as follows. First, in the context of using integrated distribution channels, consumers experience fatigue and annoyance, which has a significant negative effect on pleasure. Second, in an integrated distribution channel situation, the annoyance perceived by consumers has a positive effect on pleasure. Third, the user’s perceived pleasure in the use of integrated distribution channels had a negative (-) significant effect on user resistance and a positive (+) influence on repurchase intention. This suggests that the fatigue and annoyance perceived by the user in the integrated distribution channel situation can be a cause of suppressing pleasure and causing resistance, but that pleasure plays an important role in alleviating or eliminating resistance or inducing repurchase intention.

정은아(Euna Jung),이경은(Kyungeun Lee),김화영(Hwayoung Kim),정소라(Sora Jeong),이효섭(Hyoseop Lee),서봉원(Bongwon Suh),이원종(Wonjong Rhee) 한국HCI학회 2017 한국HCI학회 논문지 Vol.12 No.4

전력 수요가 증가하고 재생 가능 에너지에 대한 관심이 증폭됨에 따라, 수요를 억제하여 필요한 공급량을 줄일 수 있는 ‘수요반응’ 프로그램에 대한 관심이 증가하고 있다. 본 연구는 가정에 스마트미터를 구비한 국내 사용자들을 대상으로 진행된 에너지 수요반응 실증사업에 대한 실증분석으로, 사전심층 인터뷰, 설문 및 기술수용모델 분석을 통하여 가정 전력 사용자들이 수요반응 프로그램을 받아들이는 데 중요한 요인들을 살펴본다. 수요반응의 목표는 피크시간대에 미션이 발령되면 전력사용량을 평소보다 줄이는 것이며, 실험대상은 스마트미터 구입 경로와 에너지를 절감했을 때 보상받는 방식에 따라 2개의 상이한 집단으로 구성되었다. 집단 A는 주로 IoT플랫폼 서비스에 가입하는 과정에서 마케터와의 대화를 통해 전체 서비스 중 하나인 스마트미터 서비스에 함께 가입하는 경로로 수요반응 프로그램에 유입되었고, 보상으로는 통신비 할인을 받았다. 반면 집단 B는 스마트미터를 자발적으로 구매하거나 에너지 자립 마을 지역주민으로서 지자체 지원을 통해 스마트미터를 지원 받아 프로그램에 유입되었고, 미션 성공에 대한 보상은 사회적 기부를 통해 이루어졌다. 분석 결과 집단 A는 인지된 용이성과 인지된 유용성 외에 인지된 유희성도 포함된 확장된 기술수용모델이 적합함을 알 수 있었고,집단 B는 모델의 적합도가 떨어지기는 하지만 집단 A에 비해 인지된 유용성에 대한 중요도가 높음을 확인할 수 있었다. 이와 같은 결과는 집단 특성에 따른 프로그램 설계방향을 제시하여 향후 수요반응 프로그램을 효과적으로 운영하는 데에 도움을 줄 것으로 보인다. While electricity demand is generally increasing, stably controlling supply is becoming a serious challenge because renewable energies are becoming popular and often their productions are dependent on the weather. The ‘demand response’ programs can be used to complement the problems of renewable energies, and therefore their role is becoming increasingly important. This study provides an analysis of a demand response pilot that was conducted in Korea. The study first focused on questionnaire surveys and in-depth interviews, and the data was used to perform a Technology Acceptance Model (TAM) analysis. The goal of the pilot was to have the residential users reduce their power consumptions when an energy reduction mission is issued during peak load hours. The experimental subjects consisted of two groups with different characteristics. Subjects in group A obtained smart meters as an optional function of IoT platform service provided by a mobile service company, and received a charge deduction as their compensation. Subjects in group B either voluntarily purchased smart meters as individuals or received them by participating in an energy self-sufficient village program that was run by a local government, and were entitled to a donation as their compensation. With the analysis, group A was found to fit the extended technology acceptance model that includes perceived playfulness in addition to perceived ease of use and perceived usefulness. On the contrary, group B failed to fit the model well, but perceived usefulness was found to be relatively more important compared to group A. The results indicate that the residential energy groups’ behavior changes are dependent on each group’s characteristics, and group-specific DR design should be considered to improve the effectiveness of DR.

Insecticidal and Acetylcholine Esterase Inhibition Activity of Apiaceae Plant Essential Oils and Their Constituents against Adults of German Cockroach (Blattella germanica)

Hwa-Jung Yeom,Jae-Soon Kang,Eunae Kim,Sung-Woong Kim,Seon-Mi Seo,Il-Kwon Park 한국응용곤충학회 2012 한국응용곤충학회 학술대회논문집 Vol.2012 No.05

We evaluated insecticidal and acetylcholine esterase inhibition activity of 11 Apiaceae plant essential oils and their constituents against male and female adults of Blattella germanica. Of 11 Apiaceae plant essential oils tested, dill (Anethum graveolens), carvi (Carum carvi), and cumin (Cuminum cyminum) essential oils demonstrated > 90 % fumigant toxicity against male adults of German cockroach at 5 mg/filter paper. In contact toxicity test, dill (Anethum graveolens), carvi (Carum carvi), cumin (Cuminum cyminum), and ajowan (Trachyspermum ammi) essential oils produced strong insecticidal activity against male and female adults of German cockroach. Among test compounds, carvone, 1,8-cineole, trans-dihydrocarvone, cuminaldehyde, trans-anethole, p-cymene, and γ-terpinene demonstrated strong fumigant toxicity against male and female adults of B. germanica. In a contact toxicity test, carveol, cuminaldehyde, (S)-(+)-carvone, trans-anethole, thymol, and p-cymene showed the strong contact toxicity against B. germanica male and female adults. IC50 values of α-pinene, carvacrol, and dihydrocarvone against female acetylcholine esterase were 0.28, 0.17, and 0.78 mg/mL, respectively. The toxicity of blends of constituents identified in 4 active oils indicated that carvone, cuminaldehyde, and thymol were major contributors to the fumigant or contact toxicity of the artificial blend.

Cho Eunae,Kim Seong-Hun,Choi Seong Ji,Jung Min Kyu,Song Byeong Jun,Park Jin Myung,Kang Jingu,Park Won Suk,Park Joo Kyung,Woo Sang Myung,Kim Hyo Jung 거트앤리버 소화기연관학회협의회 2024 Gut and Liver Vol.18 No.1

Background/Aims: Based on their anatomy, cholangiocarcinomas (CCAs) are classified into intrahepatic, hilar, and distal CCAs. Although the diagnosis and treatment of each type of CCA are thought to be different, real-world data studies on the current practice are limited. Therefore, this study was designed to capture the current practice of diagnosing and treating perihilar CCA in Korea. Methods: We conducted a survey using an online platform. The questionnaire consisted of 18 questions designed to evaluate the current practice of diagnosing and treating perihilar CCA in Korea. The targets of this survey were biliary endoscopists who are members of the Korean Pancreatobiliary Association. Results: In total, 119 biliary endoscopists completed the survey. Of the respondents, 89.9% thought that the use of the International Classification of Diseases, 11th Revision (ICD-11) system is necessary to classify CCA. Approximately half of the respondents would recommend surgery or chemotherapy until patients were 80 years of age. For the pathological diagnosis of CCA, endoscopic retrograde cholangiopancreatography with biopsy was the most preferred modality. Routine preoperative biliary drainage was performed by 44.5% of the respondents. For operable CCAs, 64.7% of the respondents preferred endoscopic biliary drainage using plastic stents. For palliative biliary drainage, 69.7% of the respondents used plastic stents. For palliative endoscopic biliary drainage using metal stents, 63% of the respondents preferred the stent-in-stent method. Conclusions: A new coding system using the ICD-11 is needed for classifying CCAs. Guidelines for diagnosing and treating CCA based on the clinical situation in Korea are needed.
