본 연구의 목적은 영남지역의 패스트푸드 프랜차이즈 시장에서 가맹점의 관점에서 본사의 적극성, 혁신성, 위험추구성이 본사와 가맹점 간의 정서적 결속과, 이 정서적 결속이 가맹점이 지각하는 외부대표와 서비스이행에 미치는 영향을 분석하고자 하였다. 설문지를 사용하여 280명의 패스트푸드 프랜차이즈 가맹점주나 관리자의 표본으로부터 얻은 자료를, 통계방법으로 구조방정식을 사용하여 실증 분석한 결과, 첫째, 본사의 혁신성과 위험추구성은 본사와 가맹점 간의 정서적 결속에 정(+)의 영향을, 둘째, 정서적 결속은 가맹점이 지각하는 외부대표와 서비스이행에 정(+)의 영향을 미친 것으로 나타났다. 그러나 본사의 적극성은 정서적 결속에 영향을 미치지 않은 것으로 나타났다. 따라서 프랜차이즈 본사는 가맹점들이 그들에게 가지는 정서적 결속을 제고하기 위해, 첫째, 본사 자신의 혁신성과 위험추구성을 장기적 수익 추구를 위해 추구하여야 하는데, 그러하기 위해서 고객동향을 정기적으로 조사하여 많은 신메뉴와 신서비스를 개발하도록 하고, 그런 다음 그 메뉴와 서비스에 대해서 신 마케팅기법을 혁신적으로 수행하며, 둘째, 경쟁의 심화로 고수익/고위험 성향의 경영방식을 되도록 채택하고, 가격변화 등 대담한 결정이 필요하다. 또한, 본사는 적극성을 증가시키기 위하여 신메뉴/신서비스를 시장에 경쟁자보다 먼저 출하하여 시장을 선점하면서 정서적 결속을 강화할 필요가 있다. 정서적 결속을 증가시키기 위해 가맹점의 가치에 본사의 가치를 최대한 맞추는 것이 있는데, 가치가 같으면 목표가 같게 된다. 마지막으로 본 연구의 한계점과 미래의 연구방향이 논의되었다.

미국, EU, 한국의 농작업자위해성평가를 위한 AOEL 설정, 국가별 경구흡수율 적용, 노출량 산출방법을 조사하였다. 농약성분 141종에 대한 경구흡수율을 조사하였으며 경구흡수율을 적용한 농작업자노출허용량(AOEL)과 국내 설정 AOEL을 이용하여 농작업자위해성평가를 실시하였다. 미국과 EU에서는 external dose를 internal dose로 변환하기 위하여 경구흡수율 또는 피부흡수율을 적용하였으나 한국에서는 AOEL 설정 시 경구흡수율을 적용하지 않은 external dose를 사용하였다. 141종의 농약성분 중 50종이 경구흡수율 80% 미만이었으며 경구흡수율을 적용하는 경우 약 36%의 농약성분이 이전 AOEL보다 낮아질 것으로 사료되었다. 50종의 농약성분 중 한국에 등록된 농약 28품목에 대해 EU AOEL을 이용하여 농작업자위해성평가를 실시한 결과, chlorothalonil WG 등 12품목이 독성노출비가 1 이하로 계산되어 위해성이 높은 것으로 나타났다. 또한 50종 중 한국 AOEL이 설정되어 있으며 한국에 등록된 농약 24품목에 대해 한국 AOEL을 이용하여 농작업자위해성평가를 실시한 결과, chlorothalonil WG 등 6품목은 독성노출비가 1 이하로 위해성이 높게 나타났다. 한국 AOEL이 없는 4품목에 대해 EU AOEL을 경구흡수율 100%로 환산한 수치를 이용하여 위해성평가를 실시한 결과, daminozide WP 등 4품목 모두 독성노출비 1 초과로 위해성이 낮게 나타났다. 경구흡수율 적용 및 미적용 EU AOEL과 한국 AOEL을 사용한 농작업자위해성평가를 비교한 결과 oxadiagyl SC 등 6품목을 제외한 22품목에서 동일한 위해성평가 결과가 나타났다. 본 연구 결과, 농작업자 위해성 평가를 실시할 때 경구흡수율을 적용한 AOEL을 이용할 수 있을 것으로 사료되었다. 경구흡수율을 적용한 AOEL 설정 및 이용한 농작업자위해성평가를 수행하였을 때 보다 실제에 가까운 평가방법으로 판단되므로 등록농약의 평가에 적용될 수 있도록 개선이 필요할 것으로 사료된다.

The big gap between efficacy of population level prevention and expectations due to heterogeneity and complexity of cancer etiologic factors calls for selective yet personalized interventions based on effective risk assessment. This paper documents our research protocol aimed at refining and validating a two-stage and web-based cancer risk assessment tool, from a tentative one in use by an ongoing project, capable of identifying individuals at elevated risk for one or more types of the 80% leading cancers in rural China with adequate sensitivity and specificity and featuring low cost, easy application and cultural and technical sensitivity for farmers and village doctors. The protocol adopted a modified population-based case control design using 72, 000 non-patients as controls, 2, 200 cancer patients as cases, and another 600 patients as cases for external validation. Factors taken into account comprised 8 domains including diet and nutrition, risk behaviors, family history, precancerous diseases, related medical procedures, exposure to environment hazards, mood and feelings, physical activities and anthropologic and biologic factors. Modeling stresses explored various methodologies like empirical analysis, logistic regression, neuro-network analysis, decision theory and both internal and external validation using concordance statistics, predictive values, etc..

All activities relate to railway traffic involve risk and that these arise from a combination of the nature of operating activities. Proper management system is required to provide the organizational capability to reveal, analyse and address these weaknesses over time and in reasonably practicable ways, which will determine the rate at which risks can be further reduced. This paper presents a systematic risk analysis approach to safety planning and decision making, informed by a range of risk assessment techniques. An railway organization's safety management system is also presented that shows the approaches taken to minimize the external risks, and identify the shared risks and explain how they will be controlled through collaboration with others.

While oral and maxillofacial surgery such as orthognathic surgery, TMJ surgery is in progress, there always exists a risk of bleeding from maxillary artery, and this perplexes the surgeon in operation. In case of massive bleeding, it is mostly very difficult or even impossible to take an immediate action in order to stop bleeding. Even when hemostasis is possible by applying such methods as the use of local hemostatics, pressing, electrocoagulation or direct ligation, there is a high risk of secondary bleeding. Therefore, in case there is bleeding from maxillary artery, it is the best to restrain bleeding completely either by the ligation of the artery in bleeding in operation fields or by the ligation of the external carotid artery.

Carotid body tumors are uncommon tumors of the head and neck Surgery is the primary treatment for the tumor. Large carotid body tumors frequently encircle the common, internal, and exernal carotid arteries, and extensive bleeding often complicates the resection, increasing the risk of carotid artery rupture and damange to major cranial nerves. Grafting should be used in high-risk patients. We have experienced a case of carotid body tumor which encircle the common, internal and external carotid arteries, treated with ligation of external carotid artery and grafting using Gortex between common carotid artery and internal carotid artery.

Objective: To date, only a few studies have investigated the relationships between genetic polymorphisms and external apical root resorption (EARR). Hence, the aim of this systematic review was to explore the relationship between different gene polymorphisms and their association with EARR. Methods: A complete literature search was conducted by two independent reviewers. The PubMed, Science Direct, and Scopus databases were searched. In addition, the bibliographies of all textbooks and relevant articles were searched manually. A meta-analysis was performed using data entered into the electronic databases until February 28, 2017. Results: On the basis of the search, we identified 17 and 7 publications for the systematic review and meta-analysis, respectively. Odds ratio (OR) was used to evaluate the association of the interleukin 1B (+3954) polymorphism and the risk of EARR. The overall OR from the studies was used to estimate the risk of EARR. However, no association was found and no publication bias was apparent for the risk of EARR in patients receiving orthodontic treatment. Conclusions: More research on the relationship between gene polymorphism and EARR is necessary to determine better specificity of possible interactions.

Many advanced reactor designs rely on passive systems to fulfill safety functions during accident sequences. These systems depend heavily on boundary conditions to induce a motive force, meaning the system can fail to operate as intended because of deviations in boundary conditions, rather than as the result of physical failures. Furthermore, passive systems may operate in intermediate or degraded modes. These factors make passive system operation difficult to characterize within a traditional probabilistic framework that only recognizes discrete operating modes and does not allow for the explicit consideration of time-dependent boundary conditions. Argonne National Laboratory has been examining various methodologies for assessing passive system reliability within a probabilistic risk assessment for a station blackout event at an advanced small modular reactor. This paper provides an overview of a passive system reliability demonstration analysis for an external event. Considering an earthquake with the possibility of site flooding, the analysis focuses on the behavior of the passive Reactor Cavity Cooling System following potential physical damage and system flooding. The assessment approach seeks to combine mechanistic and simulation-based methods to leverage the benefits of the simulation-based approach without the need to substantially deviate from conventional probabilistic risk assessment techniques. Although this study is presented as only an example analysis, the results appear to demonstrate a high level of reliability of the Reactor Cavity Cooling System (and the reactor system in general) for the postulated transient event.

Grenfell Tower was renovated in 2014 and 2016 at a high cost to replace the exterior materials, windows and co-heating facilities of the building. The exterior materials used during the repair work were sandwich panels filled with polyethylene and plastic, which were expanded on the aluminum metal surface. It is a product called Celotex RS 5000, a low-resolution but inexpensive repair material, and is currently an external material that cannot be used in high-rise buildings. Similar domestic fire cases began to focus social attention on the safety of high-rise buildings through the Busan Residential Complex Fire (2010), Uijeongbu Urban Living Housing Fire (2015), and Ulsan Residential Complex Fire (2020), and residents' safety concerns are increasing. In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. Therefore, the purpose of this study is to examine the status of fire damage caused by domestic and foreign eruptions, domestic and international research status and related regulations on external materials and windows starting from the Grenfell Tower fire in England.
