Background: A correct estimate of the tracheal tube insertion depth can prevent complications, including endobronchial intubation and vocal cord trauma. We evaluated a new topographical method for endotracheal tube positioning relative to the carina, using a well-known prior topographical method for comparison. Methods: One hundred adult (male 50, female 50) patients were studied. The comparison topographic length (in cm)was measured by adding the distance between the right mouth corner and the right mandibular angle to the distance between the right mandibular angle and the center of the sternal manubrium. The new endotracheal tube insertion depth (in cm) was determined by adding the distance between the right mouth corner and the vocal cords, measured with the endotracheal tube itself, to the distance between the thyroid prominence and the manubriosternal joint, and then subtracting 4 cm. After intubation, the endotracheal tube was positioned properly at the right mouth corner and the endotracheal tube tip was evaluated using a fiberoptic bronchoscope at the carina. Results: The distances from the tip of the endotracheal tube to the carina were not significantly different between the methods in the same gender. However, our method allowed endotracheal tube tip placement between 3 cm and 5cm, above the carina more frequently than the prior method in males. Conclusions: The new topographical method can be used as a guide to positioning the endotracheal tubes.

부모애착이 진로 발달에 미치는 영향에 대한 개관 연구 : 국내 학술지를 중심으로

최보름(Bo Reum Choi) 단국대학교 상담학연구소 2018 상담교육연구 Vol.1 No.1

본 연구는 부모애착이 진로 발달에 미치는 영향에 대하여 국내 학술지를 중심으로 개관 한 것으로, 부모애착과 각 진로 발달 변인을 특성 별로 나누어 공통적으로 정의한 개념 및 연구 결과를 분석하였다. 연구 방법은 RISS, 국회도서관, 주요학술지 검색 등을 통하여 키워드 “부모애착” 과 “진로결정수준”, “진로결정자기효능감”, “진로탐색행동”, “진로탐색 자기효능감”, “진로정체감”, “진로성숙”, “진로사고”, “진로의사 결정유형”, “진로준비행동”, “진로포부”, “진로적응성”을 중심으로 직접적 인과 관계를 밝힌 연구를 중심으로 분석하였다. 그 결과, 연구는 진로결정수준과 진로성숙도에 편향되었고 진로적응성의 경우 부모애착과 관련한 연구는 이루어지지 않았다. 대부분 진로 발달 변인은 부모애착과 간접적인 정적 관련이 있었으나 진로결정수준과 진로탐색행동의 경우 일관되지 않은 결과가 다수였으며 유의한 영향을 미치는 것은 각 진로발달 변인 및 부모애착 하위요인별, 성별, 연구 대상마다 다양한 차이로 드러났다. 다만, 진로탐색자기효능감과 진로결정 자기효능감의 경우 직접적으로 영향을 받았다. 이에 따라, 본 연구에서는 일관되지 않은 연구 결과를 조명하여 미비하게 연구 된 분야의 필요성을 제기하고, 각 진로 변인에 따른 필요 매개 및 조절 요인을 조명하여 잘못된 부모애착으로 형성된 진로발달변인 수준을 제고 시킬 수 있는 진로 상담 및 교육의 필요성을 시사했다. Objectives: We analyzed the common notion and research result of ‘the effects of Parents Attachment on Career Development’ and we mainly reference the domestic scientific journals about it. Methods: We analyzed several researches mentioning direct causality of “parents attachment”, “career decision level”, “career decision-making self-efficacy”, “career exploration behavior”, “career exploration self-efficacy”, “career identity”, “career maturity”, “career thoughts”, “career decision-making styles”, “career preparation behavior”, “career aspiration” and “career adaptability”, and those research papers were chosen from RISS, the National Assembly Library and etc. Results: Those researches are only focused on the career decision level and career maturity without deep consideration about the parent attachment in the case of career adaptability. Most career development variables are indirectly proportional to the parent attachment. However, career exploration self-efficacy and career decision-making self-efficacy were directly affected by the career development variables. Conclusions: This work highlights inconsistent research results, and shows the reason why there should be further research needed for this branch. It also points out the need for providing some education and career counsel to correct the level of wrongly developed the career development.

최보름 ( Bo Rum Choi ),허협 ( Hyub Huh ),강화자 ( Wha Ja Kang ),신옥영 ( Ok Young Shin ) 경희대학교 경희의료원 2010 慶熙醫學 Vol.26 No.1

Noonan syndrome (NS) is an autosomal dominant disorder characterized by dysmorphic facial features in association with short stature and heart disease. A webbed neck, chest deformities, mental retardation, and bleeding disorders are also frequently associated with this pathology. The syndrome is named after Dr. Jacqueline Noonan. Patients with Noonan`s syndrome present a multiplicity of challenges to the anaesthetist, particularly with regard to spinal and airway abnormalities. Alternative methods of management should be discussed fully with patients. Careful preoperative consultation and determination of the degree of associated anomalies will help to prepare the anesthesiologist for potential problems. We describe the anesthetic management of a eight-year-old girl with Noonan syndrome for dental management under general anesthesia. We report successful management of a patient with Noonan syndrome, suspected the difficult airway, undergoing dental surgery using the induction agent with propofol and remifentanil, the muscle relaxant used after the intubation.

온라인 금융 상담 서비스에서 이모티콘 사용이 서비스 사용의도에 미치는 영향: 상담원 유형과 주관적 금융지식의 조절 효과

강영선,최보름 한국지식경영학회 2019 지식경영연구 Vol.20 No.4

Online financial counseling services are increasingly expanding with the rise of artificial intelligence based chatbots. It is very important to examine the effects of emoticons noted as alternatives for communicating emotions in online communication between consumers and companies. In this paper, we examine how the use of emoticons affects the consumer’s response and investigate the moderating roles of type of counseling agents (human vs. chatbot) and the consumer’s subjective financial knowledge. The results show that the use of emoticon in the conversation brings a positive effect on the consumer’s intention to use of online chat counseling service. When participants had relatively low subjective financial knowledge, they had higher intention to use online chat counseling services with emoticons only when the agent type was chatbot. When the type of counseling agent was human, this positive effect of the emoticon did not occur. On the other hand, when participants had relatively high subjective financial knowledge, they had higher intention to use online chat counseling service with emoticons only when the agent type was human. This study contributes to providing practical implications to build online chat counseling service using chatbot in the financial industry by studying users’ intention depending on the type of agents and the level of their subjective knowledge.

Individual Differences in Online Privacy Concern

김여립,최보름,정윤혁 한국경영정보학회 2018 Asia Pacific Journal of Information Systems Vol.28 No.4

We examined the effects of socio-demographics and personality traits on online privacy concern. We investigated this relationship in general and across different Internet functions. Using a large, diverse, population-representative sample (N = 5,242), we found that females, educated, and wealthier individuals tend to be concerned with online privacy to a greater extent. Among personality traits, agreeableness and conscientiousness were generally associated with an increased probability of being concerned with online privacy. These results imply that socio-demographics and personality traits provide explanatory insights into online privacy concern.

The Impact of Privacy Control on Users' Intention to Use Smart Home Internet of Things (IoT) Services

김민경,최보름 한국마케팅학회 2022 ASIA MARKETING JOURNAL Vol.24 No.1

Despite the diverse benefits of smart home Internet of Things (IoT) services, the biggest obstacle to the actual usage of those services is concern about privacy. However, little research has investigated the impact of privacy control on users' intention to use smart home services. Based on communication privacy management theory and privacy calculus theory, this study investigates how privacy control options affect users' perceived benefits and costs and how those perceptions affect individuals’ intentions to use smart home services by conducting an experiment. Our results showed that smart home privacy control options decreased perceived benefits and increased perceived costs. The perceived benefits and costs significantly affected the intention to use smart home security services. More intriguingly, the effect of perceived benefit was found to be stronger than that of the expected cost. This research contributes to the field of IoT and smart home research and provides practitioners with notable guidelines.

위계적 로열티 프로그램에서 고객등급 하락이 부정적 구전의도에 미치는 차별적 영향

장우정,최보름 한국고객만족경영학회 2018 고객만족경영연구 Vol.20 No.1

Customer demotion, defined as the degradation of a customer’s elevated status in hierarchial loyalty programs that award preferred customer status(e.g., Platinum, Gold membership) has been regarded as an effective way to reprioritize customers based on their recent spending level with the company. However, recent research shows a backfire effect that customer demotion decreases customer loyalty. Although previous literature demonstrated the backfire effect of customer demotion from customer retention perspectives, little is known about the possibility that customer demotion may adversely influence new customer acquisition via negative word-of-mouth(WOM). In addition, prior studies did not examine the possibility that customers may differently react to customer demotion depending on their satisfaction with the customer-company relationship, and on a customer’s power distance belief. To address these research gaps, this paper explores the impact of customer demotion on demoted customers’ willingness to spread negative WOM, and how the effect is moderated by previous relationship satisfaction between the customer and the company, and a customer’s belief about power distance. To this end, a scenario-based experiment in the context of hotel loyalty programs was conducted. The results show that customer demotion significantly increases a customer’s willingness to spread negative WOM. Furthermore, negative affect plays a critical mediating role between customer demotion and a customer’s willingness to spread negative WOM. Contrary to the expectation, the findings do not provide support for the moderating effect of relationship satisfaction between customer demotion and the willingness to spread negative WOM. However, a customer’s power distance belief moderates the customer demotion-willingness to spread negative WOM relationship, such that customers with low power distance belief who do not expect or accept that power is distributed unequally increase their willingness to spread negative WOM more dramatically. These results make theoretical and practical contributions by extending previous studies on customer demotion, and focusing on the conditions under which customers differently react to demotion. 고객의 기존 거래 실적에 따라 차등적인 지위를 부과하는 위계적 로열티 프로그램에서 고객은 때로 등급의 하락을 경험한다. 본 연구는 고객등급 하락이 새로운 고객획득 과정에 미칠 수 있는 부정적 효과를 연구하기 위해, 고객등급 하락이 기업에 대한 부정적인 구전을 퍼뜨리려는 의도에 미치는 영향을 살펴본다. 그러나 고객등급 하락이 부정적 구전의도에 미치는 영향은 일률적인 것이 아니라, 등급 하락이 이뤄지는 상황 혹은 고객의 개인적 특성에 따라 차별적일 수 있다. 따라서 본 연구는 고객과 기업이 고객등급 하락을 경험하기 전에 맺어 온 관계에 대한 만족과 고객이 지닌 권력거리에 대한 믿음에 따라 고객등급 하락이 부정적인 구전을 퍼뜨리려는 의도에 미치는 영향이 어떻게 달라지는 지를 살펴보고자 한다. 이를 위해 위계적 로열티 프로그램을 사용 중인 호텔 시나리오를 바탕으로 210명의 일반 소비자들을 대상으로 실험을 실시하였다. 연구 결과, 고객등급 하락은 고객에게 부정적 감정을 일으켜 기업에 대한 부정적인 구전의도를 높임을 확인하였다. 또한 고객이 지닌 권력거리에 대한 믿음은 고객등급 하락-부정적인 구전의도 사이의 관계를 조절하였다. 즉, 권력거리의 차이가 존재함을 잘 받아들이는 고객들은 그렇지 않은 집단보다 고객등급 하락을 경험하여도 부정적인 구전을 덜 전파하려 하였다. 이러한 연구 결과들은 최근 들어 주목받기 시작한 고객등급 하락 연구를 확장하며, 위계적 로열티 프로그램에서 주기적으로 고객등급 하락을 실행하고 있는 기업들에게 실무적 시사점을 제공한다.
