하진경,송유진 (주)에스비에스 2023 미디어경제와 문화 Vol.21 No.3

Live-commerce, which combines live streaming and online e-commerce, has recently grown into the most notable e-commerce service. Although research on various types of consumers participating in live commerce and their motives and behaviors is being discussed, this is limited to purchase intention and use intention. To fill the academic gap, this study attempts to identify consumer types according to subjective perspectives and preferences by applying the Q methodology. Ultimately, the purpose of this study is to examine the overall usage behavior of live-commerce and to promote understanding of live-commerce consumers by categorizing various types of the users with their characteristics using Q methodology. According to the results of this study, live-commerce consumers were classified into a total of seven types (systematic strategists, cautious information collectors, timid observers, conservative explorers, content viewers, purchasing power followers, and habitual shoppers). These consumer types showed differences in motivation to participate in live-commerce, preferred product type, and participation behavior. It provides diversified insights into various types of live-commerce consumers and their motivations and behaviors, and can help operators of live-commerce adjust their marketing and sales strategies to specific consumer types and improve consumers' overall live-commerce customer experience. 라이브 스트리밍과 온라인 전자상거래가 결합된 라이브커머스(live-commerce)가 최근 가장 주목받는 전자상거래 서비스로 성장하고 있다. 그러나 라이브커머스에 참여하는 소비자들의 다양한 유형과 그들의 동기, 행동에 대한 연구는 구매의도 및 이용의도에 국한되어있는 논의되고 있는 상황이다. 이러한 학술적 격차를 해결하기 위해 본 연구는 Q 방법론을적용하여 주관적 관점과 선호도에 따라 소비자 유형을 식별하고자 한다. 궁극적으로 본 연구의 목적은 라이브커머스의 전반적인 이용행태를 살펴보고 Q 방법론을 이용하여 다양한유형의 라이브커머스 소비자를 특성별로 유형화하여 라이브커머스를 이용하는 소비자에대한 이해를 도모하는 데 있다. 본 연구 결과에 의하면 라이브커머스 소비자는 총 일곱 가지 유형(체계적인 전략가, 신중한 정보수집가, 소심한 관찰자, 보수적인 탐색가, 콘텐츠 시청자, 구매력 있는 팔로워, 습관적 쇼퍼)으로 분류되었다. 이러한 소비자 유형은 라이브커머스에 참여하는 동기, 선호하는 제품 유형, 참여 행동 등에서 차이를 나타냈다. 이는 다양한 유형의 라이브커머스 소비자와 그들의 동기와 행동에 대한 다각화된 통찰력을 제공하며, 라이브커머스를 운영하는 사업자로 하여금 마케팅 및 판매 전략을 특정 소비자 유형에맞게 조정하고 소비자의 전반적인 라이브커머스 고객 경험을 향상시킬 수 있다.

하진경,배채완,강신광,임승철 대한척추신경외과학회 2011 Neurospine Vol.8 No.3

The increased use of magnetic resonance imaging (MRI) has increased the frequency of diagnosis of cavernous hemangioma, but its presentation of an epidural lesion with foraminal extension without intramedullary involvement is very rare. We describe a 31-year-old woman admitted to our department with pain in the left side of her neck and shoulder. Gadolinium enhanced cervical MRI revealed a brightly enhanced, extradural mass (1×1×2 cm sized) with widened neural foramen; after surgical excision, it was histologically confirmed as a cavernous hemangioma. Postoperatively, the patient has no neurological deficit or specific complication. Although this lesion mimicked an epidural- neurogenic tumor, its enhancement pattern indicated a cavernous hemangioma. Accurate preoperative diagnosis is necessary for treatment planning. Cavernous hemangioma must be included in the differential diagnosis of a brightly enhanced, extradural tumors.

New paradigm for cervico-isthmic pregnancy: conservative management of cervico-isthmic pregnancy leading to successful deliveries

하진경,배진곤 대한산부인과학회 2023 Obstetrics & Gynecology Science Vol.66 No.2

ObjectiveTo establish a new treatment option for cervico-isthmic pregnancy (CIP) other than termination by maintaining pregnancy from diagnosis to delivery. MethodsThis retrospective observational study included women diagnosed with CIP at Dongsan Medical Center, Daegu, Korea, from January 2014 to December 2019. Eight patients were diagnosed with CIP using transvaginal ultrasound and met the following inclusion criteria: (1) preserved and closed cervical canal; and (2) more than half of the uterine cavity above the sac was not involved in sac implantation. Five of the eight mothers decided to maintain their pregnancy after an adequate explanation of the possible risks. The same sonographer assessed fetal and maternal status every 1-2 weeks. Intra- and postoperative indicators, delivery information, and neonatal outcomes were also recorded. ResultsThe mean patient age was 36 years. In all cases, placenta accreta spectrum and placenta previa were detected using preoperative ultrasonography. A hysterectomy was performed in three cases, and all patients required intensive care unit (ICU) care. The mean operative time was 156 minutes. The rate of postpartum hemorrhage was 40%. Four viable fetuses were delivered. Birth preceding 34 weeks occurred in one patient, who required neonatal ICU hospitalization for 19 days. ConclusionConservative treatment with careful diagnosis, management, and sufficient consultation could be an alternative treatment option in women with CIP, particularly older mothers, those with subfertility, and those who expect to have limited future opportunities for a successful pregnancy. Therefore, CIP should be treated as a separate disease entity.

하진경,김창균 한국콘텐츠학회 2024 한국콘텐츠학회논문지 Vol.24 No.1

Along with the development of individual media, the spread of untact culture through COVID-19 has heightened interest in virtual worlds, leading to the emergence of virtual YouTubers. This study aims to analyze user responses to virtual YouTubers, a growing new content industry, to identify unique features of virtual YouTubers and provide empirical implications for industry advancement. To achieve this, text mining techniques were applied to analyze YouTube comments from users. The analysis revealed that current users are focused on the content provided by virtual YouTubers and the relationships among them. Additionally, eleven key features(Attractiveness, Relationality, Playfulness, Cooperativeness, Entertainment, Identity, Expertise, Connectivity, Creativity, Innovation, Star-Appeal) that users focus on in virtual YouTubers were identified, and differences in these characteristics were found depending on user engagement levels. These findings offer foundational data for understanding the virtual YouTube environment and provide opportunities for developing content strategies for sustained growth.

하진경,김희숙 한국생활과학회 2022 한국생활과학회지 Vol.31 No.2

This study examined the general characteristics of Korean Third Culture Kids (TCK) and their repatriation experience. Based on Hill’s ABC-X family stress model, coping resources such as self-efficacy; family adaptability and cohesion; social support; and the perception of cultural identity change were selected as variables to find out how they affected the degree of repatriation distress experienced among young adult Korean TCKs. An online survey was used to collect data for this study. The participants were 145 young adult Korean TCKs who had returned to Korea to live. Results from the study were as follows. First, the young adult Korean TCKs experienced a medium or moderate level of repatriation distress. They, however, perceived a high level of cultural identity change. With regards to the coping resources, young adult Korean TCKs reported a high level of self-efficacy; a medium level of family adaptability and cohesion; and a high level of social support from their friends and significant others. Second, the variables that predicted the repatriation distress were self-efficacy, social support and cultural identity change. Young adult Korean TCKs experienced more repatriation distress when they had less self-efficacy and social support resources, and the more they perceived that their cultural identities had changed.

This paper is a result of research conducted on the 800,000 m3/d capacity of A Water Treatment Plant (WTP) and 400,000 m3/d capacity of B WTP plant in operation in the Nakdong River region. We evaluated the effect of algae broom on the WTP operation based on the running data of both WTP and the data on the pre-oxidation process field test for algae control using sodium permanganate (SPM) at the B WTP. The study results showed that during the algal bloom period, the coagulant dose increased by 102% in A WTP and 58% in B WTP, respectively, and the chlorine dose also increased by 38% and 29%, respectively, which may affect Total trihalomethane (THM) production. Data such as algal populations and Chl-a, residual chlorine and THM, algal populations, and ozone dose appeared also highly correlated, confirming that algal broom affects WTP operations, including water quality and chemical dosage. As a result of the field test of B WTP, THMs appeared lower than that of the control, suggesting the possibility of the SPM pre-oxidation process as an alternative to algae-related water quality management. Furthermore, in terms of GHG emissions due to energy consumption, it was observed that the pre-oxidation process using SPM was approximately 10.8%, which is a very low ratio compared to the pre-ozonation process. Therefore, these results suggest that the SPM pre-oxidation process can be recommended as an alternative to low-carbon water purification technology.

장원규,하진경,배진곤 대한주산의학회 2020 Perinatology Vol.31 No.3

We introduce a case of triplet pregnancy with a complete hydatidiform mole coexisting two viable fetuses and important issues for prenatal care in both mothers and fetuses due to a significantly high risk for both mothers and fetuses. A 32-year-old patient conceived a triplet pregnancy after intrauterine insemination. At 14 weeks of gestation, ultrasonography revealed hydatidiform moles that were adjacent to two fetuses. Fetal karyotyping of the two fetuses showed normal results. The second baby developed fetal growth restriction at 24 weeks of gestation and preeclampsia developed at 29 weeks of gestation. At 31 weeks and one day of gestation, cesarean section was performed due to fetal distress of the second baby. Microscopically, the molar tissue was favorably diagnosed as complete hydatidiform mole. This is successful delivery report of a pregnant woman who had triplet pregnancy complicated with one complete hydatidiform mole coexisting two viable fetuses in Korea.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2),which is affiliated with the β-coronavirus subgroup, which includes SARS-CoV and Middle East respiratory syndromecoronavirus (MERS-CoV), but is far more infectious than the 2. Because it is potentially life-threatening to infantsand pregnant women with weak immune systems, clinical manifestations and vertical transmission of COVID-19 arematters of interest. Staff of the obstetrics department of university hospitals in Daegu and of the Daegu metropolitangovernment designated Daegu Fatima Hospital for the delivery of pregnant women with suspected and confirmedSARS-CoV-2 infection. Thirteen pregnant women with laboratory-confirmed COVID-19 were identified. Among themwas a 28-year-old pregnant woman who had recovered from COVID-19 and had given birth to a healthy girl at 38weeks of gestational age. We present our uncommon experience with a brief review of literatures.
