목적 : 난소 병변으로 복강경 수술을 받은 환자를 대상으로 복강경 수술의 장점, 단점, 적용범위 및 합병증 등에 대하여 알아보고자 하였다. 연구 방법 : 1994년 6월부터 2001년 9월까지 아주대학교 병원에서 난소 병변으로 진단되어 복강경 수술을 시행 받은 354명의 환자를 대상으로 후향적 고찰을 시행하였다. 결과 : 환자군의 나이 분포는 13세부터 77세였으며 평균나이는 30.9세였다. 병변의 크기는 7 cm 미만 (265예, 74.9%), 위치는 편측성 (313예, 88.4%)이 대부분이었다. 시행된 수술은 낭종제거술이 가장 많았고 (225 예, 63.6%), 난소난관절제술, 난소절제술, 나팔관절제술, 창문개구술, 조직검사의 순이었다. 수술시간은 최저 10분에서 최고 240분으로 평균 74.2분이었다. 수술 후 병리조직검사 결과에서, 편측성 난소 병변 중 조직검사를 시행한 군에서는 양성기형종이 가장 많았으며 (107/305, 35.1%), 자궁내막종, 낭선종 등의 순이었다. 경계성 종양을 포함한 악성종양은 4예에서 발견되었다 (4/305, 1.3%). 양측성 난소병변 중에는 자궁내막종이 대부분이었으며 (31/41예, 75.6%), 기형종, 낭선종, 섬유종 등의 순이었다. 수술 후 입원기간은 0일에서 19일까지로 평균 2.5일이었다. 대부분이 수술 후 합병증 없이 퇴원하였으며 (347예, 98.0%), 혈관손상으로 인한 혈관종 3예, 농양 형성 1예, 개복술로의 전환 3예가 있었다. 결론 : 복강경 수술은 난소 병변의 치료에 유용하며, 여러 가지 합병증은 적절한 환자군의 선택과 원칙에 따른 수술 및 숙련된 복강경 수술의사에 의해서 해결되어질 수 있는 문제들로 여겨진다. Objective : To assess the advantages, disadvantages, applicability, and complications of operative laparoscopy in ovarian pathologic lesions. Materials and Methods : A retrospective case series which compares 354 patients who had laparoscopic surgery at Ajou University Hospital from June, 1994 to September, 2001 for ovarian pathology. Results : The patient's ages ranged from 13 to 77 years, and their mean age was 30.9 years. Most of the lesions were less than 7 cm in size and unilateral. The operations performed were cystectomy in 225 cases (63.6%), salpingooophorectomy, oophorectomy, salpingectomy and fenestration or biopsy in order. Operative times were between 10 and 240 minutes (mean: 74.2 minutes). Pathologic examinations of unilateral ovarian tumors were performed in 305 cases. The most common pathology of unilateral ovarian tumor was teratoma (107/305, 35.1%), endometrioma and cystadenoma in order. Malignancies were found in 4 cases including borderline malignancy (1.3%). Pathologies of bilateral ovarian tumor were endometrioma (31/41, 75.6%), teratoma, and fibroma in order. Postoperative hospital stays were from 0 days to 19 days (mean: 2.5 days). There were 7 surgical complications including 3 vessel injury related hematomas, 1 abscess formation, and 3 exploratory laparotomy. Conclusions : We concluded that operative laparoscopy was useful in surgery of ovarian lesions, if there are carefully selected patients, standard procedures, and skilled laparoscopic surgeons.

승객 특성과 드론 택시 이용의도: 인지된 혜택과 비용의 매개효과

임윤경,김경진 한국상품학회 2023 商品學硏究 Vol.41 No.1

드론 택시의 상용화가 목전에 다가왔다. 그런데 드론 택시에 관한 연구는 대체로 기술적, 법규적 주제에 편향되어 있다. 따라서 본 연구는 드론 택시에 대한 승객의 인식과 태도에 주목했다. 구체적으로, 승객의 특성에 따라 드론 택시의 이용의도가 어떻게 달라지느냐를 탐구하였다. 승객의 특성을 혁신성과 동조성으로 나누었고, 매개변인으로 드론 택시의 지각된 편익 및 비용, 그리고 사회적 영향력을 제안하였다. 지각된 편익은 유용성, 용이성, 유희성으로 구성하였고, 지각된 비용은 화폐적, 심리적, 행동적 비용으로 구성하였다. 즉 승객의 특성이 편익 및 비용에 대한 인식에 영향을 미치고, 이에 따라 드론 택시의 이용 의도가 결정된다는 경로 모형을 제안하였다. 연구 결과, 승객의 혁신성은 이 경로 모형에 유의한 독립변수가 아니었다. 승객의 동조성은 유용성과 유희성, 화폐적 비용, 심리적 비용, 그리고 사회적 영향력에 효과를 미쳤다. 그리고 용이성, 유희성, 화폐적 비용, 그리고 사회적 영향력은 드론 택시의 이용의도에 효과를 미쳤다. 이 결과는 승객들이 드론 택시를 혁신적인 교통수단이라기보다는 특별하고 흥미로운 경험이라고 인식할 가능성을 암시한다. 그리고 드론 택시의 확산을 위해서 혁신적인 소비자가 아니라 영화나 드라마의 PPL 등을 활용하는 것이 더 바람직하다는 시사점을 준다. 드론 택시의 이용의도에 직접적인 영향을 주는 기능적 편익과 경험적 편익을 늘리고, 화폐적 비용은 줄이는 정책이 효과적일 것이다. 의외로 드론택시에 대한 행동적 비용과 심리적 비용은 이용의도에 부정적 영향을 미치지는 않았다. 즉 소비자는 요금만 적당하다면 흥미로운 드론 택시를 즐겨 이용할 마음의 준비가 되어 있는지도 모른다.

골유도재생술용 차폐막 적용을 위한 polyvinylidene fluoride와 polyacrylonitrile 나노섬유의 평가

임윤경,김찬,이승훈,유상준,이원표,이경현,김희중,국중기 한국섬유공학회 2019 한국섬유공학회지 Vol.56 No.3

Recently, various nanofiber membranes for guided bone regeneration using electrospinning methods have been reported. The purpose of this study was to evaluate the in vitro osteogenesis efficiency of electrospun polyvinylidene fluoride (PVDF) and polyacrylonitrile (PAN) membranes. Nano sized topography, mechanical properties, and biological evaluations were performed to compare the PVDF and PAN nanofiber membranes with the commercially available polytetrafluoroethylene (PTFE) membrane. The cytotoxicities of these membranes were evaluated using the MTT assay. Alkaline phosphatase (ALP) activity and the calcium concentration were determined to evaluate the in vitro bone formation activities of the above-mentioned membranes. Expression levels of the osteoblast differentiation marker genes (RUNX2, OSX, OCN, and COL1A1 genes) were determined using the real-time quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent (ELISA) assay. Approximately 300 nm three-dimensional porous structures, with pores connected/extending from the surface to the rear/bottom were observed in each PVDF and PAN nanofiber membrane using a scanning electron microscope. The strength and elongation of the porous structures were superior to those seen in the PTFE membrane. The cell viability, ALP activity, and calcium concentration were higher in these nanofiber membranes as compared to those in the PTFE membrane. RT-qPCR and ELISA assay analysis also showed that the nanofiber membranes had better osteogenesis efficiencies as compared to the PTFE membrane after 7 days. The results in this study demonstrate that the electrospun PVDF and PAN nanofiber membranes could potentially function as barrier membranes for bone tissue regeneration.

영어교과 마이크로티칭과 실제 영어 수업에 대한 예비교사들의 성찰 연구

임윤경 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.7

This paper was motivated by the needs to identify teaching abilities recognized by pre-service English teachers in an English education program. This study examines (1) the differences between microteaching and real classroom teaching experienced by pre-service English teachers and (2) what elements of teaching abilities they pay attention to in their own lessons. The pre-service English teachers were asked to reflect on both of their microteaching and real English class they had conducted. Drawing on the inductive logic of qualitative study, the reflective essays were collected from 21 pre-service teachers who completed their English teaching practicum. One of the salient characteristics of real classroom teaching was the students’ presence, which seems to affect the pre-service teachers’ lesson planning and classroom management. In exploring which aspects the pre-service teachers focus on in the real classroom, the criteria of the classroom management turned out to be the most challenging to the beginning pre-service teachers. Regarding the affective aspects which cannot be directly observed in microteaching evaluation, reflective approach may be used as part of the evaluation tools that can probe the unobservable qualifications. This paper suggests a few implications for teacher education programs to improve microteaching training and its evaluation tools to better assess pre-service English teachers' teaching performance. 본 연구의 목적은 영어교과 마이크로티칭과 실제 영어 수업 환경의 차이점들을 비교하고 이 두 환경에서 요구되는 교사의 능력이 어떻게 다른지를 예비 영어교사들의 시점에서 분석해봄으로써 영어 교과 마이크로티칭의 평가도구를 개선할 방안을 모색해 보는 데 있다. 이를 위해 본 연구에서는 국내 한 대학의 영어교육과에 재학하는 21명의 예비영어교사들을 대상으로 교생실습을 마치고 성찰지를 작성해서 제출하도록 했다. 그들이 교생실습 기간 동안 경험한 실제 영어수업에서 요구되는 교사의 능력과 그 전 학기에 실시했던 마이크로티칭 경험을 비교/대조하는 내용을 담은 성찰일지를 수집하여, 귀납적 논리체계에 근거해서 독립된 항목을 추출하는 방식으로 자료를 분석했다. 마이크로티칭과 일반 영어수업과의 가장 큰 차이점으로 나타난 것은 실제 학생들과의 상호 작용 여부였다. 실제 영어수업에서 예비교사들이 주목한 수업 능력은 수업 운영과 수업 기술, 수업 계획의 요소들 순이었다. 이에 대한 마이크로티칭 지도 및 평가의 개선 방안들이 제시되었고, 교사의 전문성을 계발하는 데 있어서 성찰법의 중요성이 논의되었다.

The purpose of this study was to clarify that the effect of consumer’s perception of nail store attributes has on intent to revisit (focus on independent stores) by performing quantitative research. The importance of nail stores is increasing with sales amounts and the number of workers, however, previous research in this area is not complete. The reason that this qualitative research should be done before the quantitative research is due to the scant theoretical background in this matter. As the nail market is steadily increasing, determining the factors to make a successful and influential store leading to revisits is very meaningful both academically and in business. For the quantitative study, consumers from 20 years old to less 60 years old who had purchased nail service at independent nail stores were included in the survey. Quota sampling was adopted in the areas where the independent nail stores were located from May 10th to May 30th, 2019, and 262 questionnaires were collected, and those containing insincere respondences were excluded. The most important nail store attribute was reliability (store name value, relationship with workers and A/S) and then the physical environment, economics, product, and promptness. The result depended on demographic factors- younger and lower-income respondents put a premium on the physical environment, promptness, and economics, on the other hand, older and higher-income respondents placed a priority on reliability. The correlation analysis result is that all store attributes (reliability, physical environment, economics, promptness, product) show a statistical significance. A multiple regression analysis was conducted to determine the effects of nail store attribute importance on revisit intention. Promptness, economics, and the physical environment have a statistically significant effect on the consumer’s revisit intention.

미용종사자의 삶의 만족도, 조직 내 친밀감, 장기근속의 관계

임윤경,조현진,박은준 한국미용학회 2019 한국미용학회지 Vol.25 No.5

Due to the nature of the beauty service industry, the turnover rate is increasing due to the mental and physical stress of workers, such as long-term labor, low wages and poor welfare benefits, and the current situation is that the management of hair salons has become difficult due to the exodus and complaints of consumers. This study sought to increase the long-term of workers. This study collected data using questionnaire and used SPSS 22.0. To see the effects between each parameter, we used regression and parametric regression to see the effects of the parameters. As a result, unmarried women in their 20s had the highest response rate, while their monthly salary was more than 2 million won and less than 2.5 million won. In addition, worked for more than a year and less than five years, and many attended or graduated from college. said that there were many designers in job and that many people had two days off a week. In addition, the satisfaction of life was derived by two factors: external satisfaction and internal satisfaction, and intimacy and long-term service were derived as a single factor. Finding out the effect of life satisfaction on intimacy and long-term service, all found to have a definition effect, and intimacy was having a definition effect on long-term service. In addition, intimacy has all been shown to have a mediated effect in the relationship between external satisfaction, inner satisfaction and long-term service. Therefore, efforts will be needed to enhance trust and intimacy with employees, such as thinking communication with employees at Salon is important and engaging in activities that allow them to spend extra time together.

The Effect of Short-term Bed-rest on Radial Pulse in Healthy Subjects

임윤경,박광석 사단법인약침학회 2014 Journal of Acupuncture & Meridian Studies Vol.7 No.3

The objective of this study is to investigate the effects of short-term bed rest on the radial pulse in healthy subjects. Twenty-one healthy volunteers participated in this study. Their radial pulse was measured at different measuring positions using a multi-step tonometry system. The participants took 30 minutes of bed rest and their radial pulse was measured before and after the bed rest. The effects of bed rest on the radial pulse were analyzed. The pulse area, the amplitudes of h4 and h5, the pulse period, and the diastolic pulse proportion increased with short-term bed rest, whereas the proportions of systolic and hightension pulse and the fundamental frequency of the pulse wave decreased with short-term bed rest. All the changes were in the same direction in both male and female participants at all measuring positions; however, some parameters chan- ged more in women than in men, and some changed more at the distal position than at the proximal position. In shortly, Short-term bed rest induces significant changes in the radial pulse of healthy subjects. The results of this study could be used as a control refer- ence for clinical acupuncture studies with participants lying on a bed for acupuncture treatment.

임윤경,이찬,이현진,박광석 사단법인약침학회 2014 Journal of Acupuncture & Meridian Studies Vol.7 No.6

In this research, radial pulse differences according to gender and measuring positions in healthy individuals were investigated in an objective manner. A total of 372 healthy vol- unteers (189 males and 183 females) participated in this study. The radial pulse was measured at six different measuring positions using a multistep tonometry system. The pulse data were compared between males and females and between different measuring positions. Compared to the pulses in females, those in males were deeper and slower, with a longer diastolic proportion and a shorter systolic proportion. Amplitude of the radial pulse increased as it went distal. The pulse was deepest at the Cheock position and shallowest at the Gwan position. Compared to the right pulse, the radial augmenta- tion index was higher and the main peak angle was larger in case of the left pulse. The results of this research show that the radial pulses in healthy individuals differ signifi- cantly according to gender and measuring positions.

임윤경,곽태기 한국의상디자인학회 2019 한국의상디자인학회지 Vol.21 No.3

The purpose of this study was to clarify store attributes for nail stores (focusing on independent stores) by qualitative research. Even though the nail market is showing a steady increase in terms of sales amounts, and the number of stores, related studies were very rare. Meanwhile, as long as the nail market is growing, many stores are suffering from bad business performance because of new nail stores are relatively easier to open than beauty or hair stores, but the nail stores don't have a discriminated marketing strategy. As nail the market is rapidly increasing, finding factors that led to success for nail stores is very meaningful, both for academics and business. The reason that qualitative research should be done before the quantitative research is due to scant theoretical background concerning this matter. For this qualitative research, 8 experts who are operating nail stores as an owner or a manager or a professor at a university who had over 5 years of related working experience were included. The attributes for nail stores were derived using one-to-one in-depth interviews conducted from March 3 to May 31, 2019. As a result of the qualitative studon the attributes for nail stores, it turned out that there were 5 factors– physical environment, product, speed, profitability, and reliability. Physical environment, product, and profitability were mentioned in most related surveys, but some details showed that and speed and reliability have been newly highlighted. Many unknown issues that were not easy to acquire from common academic research are included. After this study, I hope that many marketers may get basic conditions to apply to real businesses and that they can use it as effective data for the following quantitative research.

임윤경,유소영,장영윤,이병천,이대성,국중기 한국식품과학회 2020 Food Science and Biotechnology Vol.29 No.4

The purpose of this study was to determine the anti-inflammatory and in vitro bone formation effects of Garcinia mangostana L. (mangosteen) and propolis extracts. Immortalized human gingival fibroblasts (hTERThNOF) cells were treated with Porphyromonas gingivalis KCOM 2804 lipopolysaccharide followed by treatment with mangosteen and propolis extract alone or in combination. Expression levels of inflammatory cytokines were evaluated by enzyme-linked immunosorbent assay. Effect of mangosteen and/or propolis extracts on mineralization of MG-63 cells was evaluated by alkaline phosphatase activity and alizarin red S staining. Group mangosteen extract complex 1:34 (1 lg/ml mangosteen extract and 34 lg/ml propolis extract) significantly reduced expression levels of IL-6, IL-8, and PGE2. It had higher than other groups in vitro bone formation effect on MG63 cells. These results suggest that mangosteen and propolis extract complex could be used in the prevention and treatment of periodontal disease.
