신경민,조선미,신윤미,박경순 대한의학회 2013 Journal of Korean medical science Vol.28 No.11

Depression during adolescence is critical to the individual’s own development. Hence, identifying individuals with high-risk depression at an early stage is necessary. This study aimed to identify childhood emotional and behavioral risk factors related to depressive symptoms in Korean adolescents through a longitudinal study. The first survey took place from 1998 to 2000, and a follow-up assessment conducted in 2006, as the original participants reached 13-15 yr of age. The first assessment used the Korean version of Child Behavior Checklist and a general questionnaire on family structure, parental education, and economic status to evaluate the participants. The follow-up assessment administered the Korean Children’s Depression Inventory. Multiple regression analysis revealed that childhood attention problems predicted depressive symptoms during adolescence for both boys and girls. For boys, family structure also predicted adolescent depressive symptoms. This study suggests that adolescents with attention problems during childhood are more likely to experience depressive symptoms.

기업의 영업 전략이 영업사원의 가치기반판매와 성과에 미치는 영향 : 의료산업을 중심으로

신경민,송태호 한국마케팅관리학회 2021 마케팅관리연구 Vol.26 No.1

B2B 산업에서 영업의 중요성이 높아짐에 따라 최근 영업을 마케팅의 촉진수단이 아닌 기업경영의 중요한 기능으로 인식하여 영업 전략의 필요성이 높아지고 있다. 이에 본 연구에서는 B2B 산업인 의료 산업을 중심으로 기업의 영업 전략이 영업사원의 판매 행동인 가치기반판매와 영업성과에 미치는 영향 을 분석하여 영업 전략의 효과성을 규명하고자 하였다. 이를 위해 의료기기와 제약 기업의 영업팀장 이 상 91명과 영업사원 163명의 자료를 바탕으로 다층모형을 활용하여 분석하였다. 분석결과 영업 전략의 고객 세분화는 영업사원의 가치기반판매 활동에, 고객 우선순위 부여는 영업성과에 유의한 정(+)의 영 향을 미치며, 영업사원의 가치기반판매 활동은 영업성과에 유의한 정(+)의 영향을 미치는 것으로 밝혀 졌다. 본 연구의 결과는 기업의 영업 전략이 영업사원의 가치기반판매 활동과 영업성과에 차별적 영향 을 보여줌으로써, 영업 전략과 가치기반판매 그리고 영업성과에 대한 새로운 이론적 관점을 제시하고 있다. 실무적으로는 의료 산업과 같은 B2B 산업에서 영업 전략의 차별적 성과향상 과정에 대한 이해에 따른 새로운 고려 사항을 제시하고, 가치기반판매의 실증적 효과를 바탕으로 새로운 영업 시스템의 필 요성을 제안한다. As the importance of sales increases in the B2B industry. Accordingly, the need for sales strategies is increasing as sales are recognized as an important function of corporate management, not as a means of promoting marketing. Therefore, this study attempted to investigate the effectiveness of the sales strategy by analyzing the effect of the sales strategy on the value-based selling and sales performance of salesforce, focusing on the medical industry. To this end, a multilevel model was used to analyze the data based on 91 sales team leaders or more and 163 salesforces of medical equipment and pharmaceutical companies. As a result of the analysis, it was found that the customer segmentation of the sales strategy had a significant positive (+) effect on the salesforce's value-based selling activities, and the customer prioritization had a significant positive effect on the sales performance. It was found that salespeople's value-based selling activities had a significant positive (+) effect on sales performance. These results show that a company's sales strategy an important role in improving sales performance by promoting value-based sales activities of salespeople. This study theoretically suggests a new theoretical basis for sales strategy and value-based sales, and in practice the necessity of establishing a sales strategy in B2B companies and the need to establish an education system for salespeople for value-based sales.

Post-Traumatic Cognition Mediates the Relationship between a History of Sexual Abuse and the Post-Traumatic Stress Symptoms in Sexual Assault Victims

신경민,정영기,신의진,김미란,김남희,김경아,이한별,장형윤 대한의학회 2017 Journal of Korean medical science Vol.32 No.10

More than half of all sexual assault victims report experiencing sexual victimization more than once. The aim of this paper was to determine the role post-traumatic cognition plays in the relationship between a history of sexual abuse and post-traumatic stress symptoms in sexual assault victims. The relationship between a history of sexual assault and the severity of post-traumatic stress symptoms was investigated retrospectively using data from a sexual assault crisis center in Korea. Data on psychological symptoms were collected in person at the initial assessment and by telephone 1 month later using the Post-traumatic Cognitions Inventory and the Post-traumatic Stress Disorder Symptoms Scale: Self-report Version. Of 105 women included in the analysis, 10 (9.5%) reported prior sexual abuse and were classified as sexually revictimized. Revictimized women had more post-traumatic negative cognition at initial assessment (t = −2.98; P = 0.004) and more post-traumatic symptoms at 1 month follow-up (t = −2.39; P = 0.019) than singly victimized women. At 1 month follow-up, the severity of post-traumatic stress symptoms had increased in revictimized women but had decreased slightly in singly victimized women. Negative post-traumatic cognition fully mediated the association between a history of sexual abuse and the severity of post-traumatic stress symptoms. Early detection of sexually revictimized women and tailored service and treatment intervention is needed to better serve this group of victims. Interventions targeted at preventing revictimization or post crime victimization may also help victims recover from the trauma and prevent future abuse.

A Pilot Study of a Cognitive-Behavioral Group Interventionon Parenting Stress for Mothers Affected by Breast CancerKyoungmin Shin & Sunmi Cho Abstract: Being a mother diagnosed with breast cancer can cause high parenting stress and adversely affect their psychological well-being. However, psychological intervention programs to reduce parenting stress of patients with breast cancer in Korea are scarce. For investigating the effect of cognitive-behavioral group intervention for breast cancer patients on parenting stress, 10 mothers affected by breast cancer who reported high parenting stress were recruited. Four 2-h cognitive-behavioral group interventions were delivered at 1-week intervals. Self-report questionnaires to evaluate mental health of mother and child were obtained at the pre-treatment, post-treatment and follow-up. After the programme, BDI and PSI-SF total score declined significantly. The analysis showed no significant effect for time in BAI and KPRC scores. Our results suggest that intervention focused on parenting stress and parent-child relationship may have an effect in increasing psychological well-being for younger women affected by breast cancer.

Prediction of flow stress of metallic material and interfacial friction condition at high temperature using inverse analysis

신경민,지석환,김낙수 대한기계학회 2010 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.24 No.3

Inverse analysis is a method for determining material parameters by minimizing the difference between experimental and the finite element (FE) simulated results, such as the load-stroke curve and barreling shape of a deformed specimen using an optimum design technique. In this study, ring compression tests were conducted to predict the flow stress of materials and interfacial friction conditions. Cylinder compression tests were conducted under the same process conditions to estimate the validity of the data obtained from the ring compression tests. By comparing the experimental results with the FE simulated results, it was confirmed that flow stress and the interfacial friction condition obtained from the ring compression tests, as well as their inverse analysis, are quite reasonable. The validity of both the flow stress function and the interfacial friction condition using the above procedures was verified by the experiments.

A Pilot Prospective Study of the Relationship among Cognitive Factors, Shame, and Guilt Proneness on Posttraumatic Stress Disorder Symptoms in Female Victims of Sexual Violence

신경민,조선민,이수현,정영기 대한의학회 2014 Journal of Korean medical science Vol.29 No.6

This study prospectively examined the relationships among cognitive factors and severity ofPosttraumatic stress disorder (PTSD) symptoms in female victims of sexual violence. Thirtyeightvictims of sexual violence recruited from Center for Women Victims of Sexual andDomestic Violence at Ajou University Hospital. Cognitive factors and PTSD symptom wereassessed within 4 months of sexual violence and 25 victims were followed-up 1 monthafter initial assessment. Repeated-measured ANOVA revealed that PTSD incidence andseverity decreased over the month (F [1, 21] = 6.61). Particularly, avoidant symptomsmight decrease earlier than other PTSD symptoms (F [1, 21] = 5.92). This study alsoshowed the significant relationship between early negative trauma-related thoughts andsubsequent PTSD severity. Shame and guilt proneness had significant cross-sectionalcorrelations with PTSD severity, but did not show associations when depression severity iscontrolled. Our results suggest that avoidant symptoms might decrease earlier than otherPTSD symptoms during the acute phase and that cognitive appraisals concerning thedangerousness of the world seem to play an important role in the maintenance of PTSD(r = 0.499, P < 0.05).
