서비스 기업에게 서비스스케이프(서비스 전반의 물리적 환경)를 관리하는 것이 바람직한 고객 반응을 이끌어내는데 중요한 것처럼, 최근 들어 바람직한 종업원 반응을 이끌어내기 위한 물리적 근무 환경 관리가 중요해지고 있다. 직원의 동기부여를 설명하는 전통적 이론인 Herzberg(1966)의 2요인 이론에 의하면, 물리적 근무 환경은 직원의 불만족이 일어나지 않도록 할 뿐, 직무 만족이나 동기 부여를 제공할 수 없는 ‘위생 요인’으로 여겨져 왔다. 본 연구는 위생요인으로 평가절하되던 물리적 근무 환경의 중요성을 재검토하였다. 첫째, 다양한 환경에서의 물리적 환경에 대한 기존 연구들을 바탕으로 본 연구는 ‘워크스케이프(workscape)’라는 포괄적인 개념을 제안하고, 이를 ‘직원에게 영향을 미치는 사무공간 내/외부의 물리적, 사회적, 위치적 환경’이라고 정의하였다. 둘째, 서비스스케이프, 헬스케어 서비스의 물리적 환경, 사무실의 물리적 환경 관련 문헌에 대한 폭넓은 검토와 실무자 인터뷰, 13개 기업의 520명의 직원들에게 실시한 설문조사 분석 결과를 토대로, 본 연구는 ‘워크스케이프’의 7개의 결정요인과 22개의 측정문항을 도출하였다. 7개의 결정요인은 쾌적성, 개방성, 프라이버시, 기분전환성, 혼잡성, 구성원의 외적 특성 및 입지성이다. 본 연구는 ‘서비스스케이프’ 개념을 물리적 근무 환경으로 확장시키고, 측정문항을 개발한 최초의 연구이다. 또한, 본 연구 결과는 실무자들이 ‘워크스케이프’ 관리의 중요성을 인식하고, 물리적 근무 환경의 어떠한 측면을 관리하는 것이 중요한지 더 잘 이해할 수 있도록 도울 것이다. Just as managing ‘servicescape’ is important for service firms to induce desirable customer responses, the importance of managing physical work environment for employees to obtain desirable employee reactions has gained growing importance recently. While challenging the traditional notion of physical work environment as a ‘hygiene’ factor, this study revisits the importance of physical environment for employees. First, drawing on extant research on physical environment in various settings, this study proposes a comprehensive concept of ‘workscape’ as ‘the physical, social, locational environment of inside and outside of the workplace impactful on employees.’ Second, based on extensive reviews of literature on servicescape, healthcare facilities, and physical work environment; practitioner interviews; and analysis outcome of a self-administered survey among 520 employees of 13 companies, this study derives seven determinants of ‘workscape’ and develops a 22-item scale to measure ‘workscape.’ The seven determinants are pleasantness, openness, privacy, refreshingness, crowdedness, other’s appearance, and location & surroundings. This study is the first to extend the concept of ‘servicescape’ comprehensively to the physical work environment and empirically develop its scale. The findings of this study can help practitioners to realize the importance of managing ‘workscape’ and better understand which aspects of the physical work environment are important to manage.

이미리(Lee, Mi Ri),이청원(Lee, Cheong-Won),김도경(Kim, Do-Gyeong) 대한교통학회 2013 대한교통학회 학술대회지 Vol.68 No.-

본 연구에서는 공사구간을 효율적으로 운영관리 하기 위해서 이동성과 안전성의 두 가지 측면을 만족하는 완화구간 길이 산정한 다. 현재 도시고속도로는 교통량이 많고 주행속도가 높아 도로점용 공사 시 교통사고 위험뿐만 아니라 차로 수 감소, 차로 변경, 가 감속 등의 증가로 마찰이 증대되어 교통정체를 야기한다. 도시고속도로 여건에 적합한 도로점용 공사구간 교통량에 관한 연구가 미 비하여 현장자료를 통해 공사구간 평균 최대 통과 교통량을 산정하였다. 이를 기준으로 Simulation을 이용하여 편도 2~4차로 1차로 도로점용 공사 시 완화구간 길이를 100~500m 까지 100m 간격으로 변화시키며 분석한 결과, 편도 차로 수에 따라 동일한 완화구간 길이로 운영하는 것보다는 편도 차로 수 별로 다르게 점용하여 운영하는 것이 우수하다는 결과를 도출하였다.

본 연구는 도시 고속도로의 편도차로수별 공사구간 기본용량 산정을 위한 것이다. 이를 위하여 현장 자료 및 교통관리센터자료를 수집하고, 4가지 분석방법을 적용한다. 평균 최대 관측 교통류율 분석법과 Headway 분석법, 회귀 분석법, Parameter Inspection 분석법 중 신뢰성이 높은 평균 최대 관측 교통류율 분석법 및 Headway 분석법의 결과를 값을 기반으로 공사구간 기본용량을 산출한다. 설계속도 80km/h인 도시고속도로 공사구간 평균용량은 약 1,650pcphpl로 추정된다. 편도 4차로 공사시 용량은 약 1,700pcphpl, 편도 2차로 공사시 용량은 약 1,600pcphpl이며, 용량 감소율은 각각 0.15, 0.2이다. 편도차로수가 적을수록 용량이 더 감소하는 것으로 보인다. 또한 결과의 검증을 위하여 파라믹스 시뮬레이션 분석을 통해 편도 차로수별 용량을 산정하고, 자료분석 산출용량을 비교한다. 본 연구는 도시 고속도로의 공사구간의 효율적이고 체계적인 관리 수립에 기여할 수 있다. This paper aims to estimate work zone base capacity by the number of lanes for urban freeway. To do this, data were collected from the field survey and the database system maintained by traffic control center, and analyzed with four different methods such as the average maximum observation flow rate, headway, regression analysis, and parameter inspection. The work zone base capacity for urban freeway is estimated based on the average maximum observation flow rate and headway method, which are more reliable methods compared to others. The average capacity is 1,650pcphpl when the design speed is 80km/h. The capacity of four lanes one-way work zones was about 1,700pcphpl, while one of 2 lanes one-way work zones was about 1,600pcphpl. The capacity reduction rates for each are 0.15 and 0.2, respectively. The smaller the number of lane is, the more base capacity is reduced. For verification of results, we estimate the capacity by simulation analysis using PARAMICS, and compare with analytical results by a statistical method. This research can be used for efficient and systemic management of work zone in the urban freeway.

Purpose: To assess the effect of pars plana vitrectomy and gas tamponade on corneal endothelial cell density. Methods: The corneal endothelial cell density in 145 eyes that underwent pars plana vitrectomy was examined with a noncontact specular microscope 3 months pre- and post-operation. The subjects were divided as follows: Group 1 (32 eyes) underwent pars plana vitrectomy, group 2 (26 eyes) underwent pars plana vitrectomy combined with gas tamponade, group 3 (34 eyes) underwent pars plana vitrectomy combined with phacoemulsification and group 4 (48 eyes) underwent pars plana vitrectomy combined with phacoemulsification and gas tamponade. The changes in corneal endothelial cell density between groups was compared. Results: The mean endothelial cell loss was more significant in group 2 than in group 1 (p = 0.012), and there was no difference between groups 3 and 4 (p = 0.063). However, after excluding 6 eyes that had blood in the center of the corneal endothelium as a result of being in the prone position following gas tamponade, the mean endothelial cell loss in group 2 was not less than in group 1. In eyes with blood in the corneal endothelium, endothelial cell loss significantly increased (p < 0.001). Conclusions: The results of this study suggest that ophthalmic surgeons should attempt to carefully control bleeding and sufficiently irrigate the vitreous during pars plana vitrectomy combined with gas tamponade.

망막분지정맥폐쇄에 합병된 황반부종에서 유리체강내 베바시주맙 주입술이 삶의 질에 미치는 영향

김지욱,최경식,이미리,이성진,Jee Wook Kim,MD,Kyung Seek Choi,MD,PhD,Mi Ri Rhee,MD,Sung Jin Lee,MD,PhD 대한안과학회 2012 대한안과학회지 Vol.53 No.10

Purpose: To evaluate the impact of intravitreal bevacizumab injection on visual function and vision-related quality of life (VR-QOL) in patients with branch retinal vein occlusion (BRVO) using the Korean version of the National Eye Institute Visual Function Questionnaire 25 (K-NEI-VFQ-25). Methods: This study included 32 normal control subjects and 32 patients with BRVO. The Korean version of NEI-VFQ-25 was answered by the patients with BRVO before and 3 months after intravitreal bevacizumab injection, as well as by normal control subjects. Clinical data were collected, including central macular thickness (CMT), total macular volume (TMV) (using time-domain optical coherence tomography [OCT]), and best corrected visual acuity (BCVA). Results: Visual acuity, CMT, and TMV significantly improved 3 months after intravitreal bevacizumab injections. No bevacizumab- related systemic or ocular adverse effects following intravitreal drug injections were observed. Significant improvement in the VFQ-25 composite score was observed in patients with BRVO. Subscale scores, including general vision, near activities, distance activities, social functioning, mental health, role difficulties, dependency, and peripheral vision, improved after injection. However, subscale scores regarding general health, ocular pain, driving, and color vision did not improve significantly. Conclusions: Intravitreal bevacizumab injection appears to be an effective treatment for visual function, as well as VR-QOL in macular edema secondary to BRVO. However, improvement of driving function and color vision appears to require a longer recovery time than visual function. J Korean Ophthalmol Soc 2012;53(10):1465-1471

Purpose: To assess the influence of body position on intraocular pressure (IOP) in patients who underwent vitrectomy and intraocular gas tamponade. Methods: Patients who did not undergo any surgery were defined as Group 1. The remaining patients were divided into 3 groups according to the surgery performed (Group 2; cataract surgery, Group 3; vitrectomy and cataract surgery, Group 4; vitrectomy with intraocular gas tamponade and cataract surgery). IOP was measured by a non-contact tonometer, Goldmann applanation tonometer, and Tono-Pen in the sitting, supine, and prone positions. Results: The difference of IOP measured in the sitting position among the 4 groups was not significant. IOP was significantly elevated by 2.04 mm Hg on average when the posture was changed from sitting to supine or prone in all 4 groups. The IOP discrepancy between supine and sitting positions was significantly greater in group 4 by 3.61 mm Hg than the other groups (p = 0.003, ANOVA test). The IOP difference between the prone and sitting position was also significantly higher in group 4 by 3.82 mm Hg than the other groups (p = 0.001, ANOVA test). Conclusions: The patients with vitrectomized gas tamponade eyes had a mean IOP increase of 3.82 mm Hg when the position was changed from sitting to prone. When performing vitrectomy and intraocular gas tamponade on patients in the prone position, an IOP elevation should be monitored thoroughly.

Objectives: The purpose of this study was to compare the health status of residents who were exposed to the Iksan industrial area in the living environment and those who were not exposed to such a source of industrial activity through a questionnaire survey designed to appraise the residents’ health levels. Method: The authors conducted a health questionnaire survey of 1,012 residents around Iksan regarding their personal information, physician-diagnosed disease history, odors experienced, and more. Logistic regression was performed to identify the associations between hazardous chemical exposure and physician-diagnosed diseases. Result: Logistic regression shows significant differences in allergic rhinitis, cardiovascular disease, hypertension, dyslipidemia, liver disease, and osteoporosis. Odors were experienced by 88.0% of the survey group. The seasons were summer (71%) and spring (24.9%). Conclusion: For allergic rhinitis, cerebral cardiovascular disease, and hypertension, which were significantly higher in the case group than in the control group in the disease diagnosis and disease treatment history of physicians, it was difficult to completely eliminate the association with odor exposure in the Iksan Industrial Complex. It is considered that it has affected nearby residents. This study means that a correlation between chronic diseases has been found through regression analysis, and furthermore, this result can be used as a basis for sampling for secondary epidemiological surveys.

김창훈 ( Chang Hoon Kim ),이미리 ( Mi Ri Lee ),유원섭 ( Weon Seob Yoo ) 한국보건경제정책학회(구 한국보건경제학회) 2014 보건경제와 정책연구 Vol.20 No.4

복합만성질환은 흔하게 나타나는 건강문제이며, 의료이용과 비용을 향상시키고, 건강결과를 악화시키는 것으로 알려져 있으나, 본격적인 연구가 시행되지 않고 있다. 이 연구는 복합만성질환자의 다빈도 만성질환조합의 유병양상과 그 비용을 산출하고 복합만성질환에 대한 중재전략을 모색 시 질병부담 측면에서 우선순위가 높은 다빈도 질병조합군을 확인하고자 하였다. 2011년 한국의료패널 자료를 활용하여 시설에 거주하지 않는 20세 이상 성인을 대상으로 다빈도 질환조합을 확인하고 노인층과 청장년층으로 구분하여 1인당 평균의료비와 질병조합군별 총 의료비용을 추정하였다. 청장년층에서 유병율 기준으로 가장 빈도 높은 2개 질환조합과 3개 질환조합은 각각 고혈압-당뇨(3.6%)와 고혈압-관절염-골다공증(0.9%)이었고, 노인층에서는 고혈압-관절염(8.6%), 고혈압-고지혈증-관절염(3.1%)이었다. 복합만성질환 중 가장 많은 비용이 지출되는 질환조합은 청장층의 경우 천식-만성폐쇄성폐질환(2개 질환조합)과 고혈압-관절염-당뇨(3개 질환조합)이고, 노인층의 경우 고혈압-관절염(2개 질환조합), 고혈압-고지혈증-관절염(3개 질환조합)이었다. 이 연구를 통해 확인된 복합만성질환을 구성하는 주요 질환들과 다빈도 질환조합군들은 복합만성질환자들의 의료이용을 적정화하고, 건강결과를 향상시키며, 보건의료비용을 감소시키기 위한 전략과 중재를 모색할 때 우선순위 높은 표적집단으로 활용할 수 있을 것이다. Background: Multimorbidity is common health condition especially in the older population and associated with high levels of healthcare utilization and costs. But little is known about its frequent patterns and association with healthcare utilization or cost in Korea. The purpose of this paper is to investigate the prevalent combinations of common chronic conditions and their effect on healthcare cost and to find out target groups for an intervention to relieve disease burden. Methods: We analyzed the Korea Health Panel Data representing non-institutionalized Korean adult populations aged 20 and over with chronic conditions. Also we identified the most prevalent combinations of common chronic conditions and estimated their mean and total healthcare cost for the elderly and nonelderly patients. Results: The most common dyad and triad of chronic conditions for the nonelderly patients are hypertension-diabetes(3.6%), hypertension-arthritis-osteoporosis(0.9%) and for the elderly are hypertension-arthritis(8.6%), hypertension-hyperlipidemia-arthritis(3.1%). The most burdensome combinations for the nonelderly are asthma-COPD, hypertension-arthritis-diabetes and for the elderly are hypertension-arthritis, hypertension-hyperlipidemia-arthritis(dyad and triad, respectively) Conclusion: Our findings suggest that national strategy and intervention for chronic diseases should place the priority to the multimorbid population causing the highest medical cost.
