In a retailer’s distribution center, workers use a Digital Assorting System (DAS) to assort the products destined for convenience stores, DAS is composed of truck arrival unloading areas (receiving area), aisle-assorting areas (depot area), and cell-assorting areas (cell area). In the depot area, workers assigned to the aisle-assorting operation partition the boxes containing products assigned to each side. Workers assigned to the cell-assorting operation transport the boxes to their cell area and place items in boxes on appropriate cell for subsequent delivery to convenience stores. This paper analyzes the effects of the number of decks and aisles, the assignment of products in the decks to the depots, and the worker assignment methods in the cell areas. We build a simulation model to analyze work-in-process (WIP) and completion time (CT) for feasible configurations and their combinations. Using a simulation model, we analyze the effects of operational policies and logistics system layout on productivity. 편의점 점포를 거래처로 하는 물류센터에서 작업자는 디지털 어소팅 시스템(Digital Assorting System, DAS)을 통해서 제품을 각거래처로 분류한다. DAS 시스템은 트럭이 도착하여 제품을 하차하는 지역(receiving area), 제품을 각 통로 별 수량에 맞게 나누는 지역(depot area), 마지막으로 통로 내 각 셀(cell) 별로 제품을 분류하는 지역(cell area)으로 구성된다. Depot area에 할당된 작업자는 각 통로 별 필요한 수량에 따라 박스로 나누는 작업을 수행한다. Cell area에 할당된 작업자는 통로 내에서 각 셀에 필요한 수량의 제품을 분배한다. 각 셀에 담긴 제품들은 작업 후 각 편의점 거래처로 배송된다. 본 연구는 데크(deck)와 통로 개수, 데크에서 데포(depot)로의 제품 할당에 대한 운영정책, 그리고 Cell area 내의 작업자 이동경로 규칙이 DAS 시스템의 생산성에 미치는 영향을 분석한다. 이를 위해서 가능한 레이아웃 구성에 따라 WIP와 작업완료시간(CT)을 분석할 수 있는 시뮬레이션 모델을 개발하였 다. 시뮬레이션 실험을 통하여 운영정책과 작업자 이동경로 규칙, 그리고 레이아웃 구성이 생산성에 미치는 영향을 분석하였다.

독일기업 문화마케팅 연구: 문화예술 후원과 활용 중심으로

이정만 ( Jeong Man Lee ) 한독경상학회 2012 經商論叢 Vol.30 No.2

현대산업사회는 창의성과 혁신성이 기업경쟁력의 원동력이 되는데, 문화예술의 기업경영접목을 통하여 이룰 수 있다. 많은 기업들이 사회공헌전략으로 문화예술을 후원하고 있는데, 단순한 기부차원을 넘어 기업이미지 개선, 판매촉진, 고객확보 등의 상업적 전략으로 사용하고 있다. 최근에 와서는 대기업을 중심으로 직원동기부여 수단으로 활용하고 있는데, 회사자부심상승, 직원간 유대감 강화, 직무성과향상 등의 경영조직을 촉진시키기 위한 목적으로 사용하고 있다. 기업의 문화예술 후원은 문화예술산업 활성화의 직접효과와 창의적 문화사회를 이루는 간접효과도 가져온다. 독일은 한국과 마찬가지로 유지 발전해야할 문화유산이 많은 국가로 국가에서 적극적으로 문화예술을 지원하고 있고, 기업은 보완적인 역할은 하고 있다. 기업의 후원 뿐 아니라 많은 민간재단 및 시민단체가 문화예술을 후원하고 있으며, 문화예술산업은 독일 경제의 부가가치창출에 많은 기여를 하고 있다. 국가 비교현황에서 독일기업의 문화예술 후원액수는 영국보다 높지만, 문화정책을 시장주의·비정부에 중점을 두는 미국에 비해서 낮다. 독일어권 기업의 문화예술 후원의 목적으로는 ``사회공헌``이 가장 많았고, 그 뒤로 ``상업/소통``,``직원동기부여``였다. 한국은 문화예술활용분야에 있어서 음악관련 장르가 다수를 차지했는데,독일어권 기업은 미술, 음악 등 다양한 장르를 활용하였다. 독일기업의 대다수가 지리적 연고를 중요시여기는 성향으로 기업크기와 관계없이 지역 문화예술단체 후원이나 그 활용을 선호하였다. 이는 독일기업들이 속한 지역이나 지방을 중시하는 형태로 동반발전 의식이 강하다고 해석할 수 있다. 문화예술 후원의 가장 큰 효과로는 기업``이미지상승``이었는데, 그 뒤로 ``기업구조에 긍정적 영향``, ``명성획득``, ``직원간 동질감확인``, ``고객충성도상승``, ``브랜드강화`` 등 이었다. 기업크기가 클수록 ``직원의 동기상승`` 항목이 상승하여 통계적유의성이 상당이 높았으며, ``직원간 동질감확인``도 유의성이 높았다. 따라서 기업크기가 클수록 문화예술 후원으로 기업내부 효과가 증가하는 것으로 해석된다. 많은 후원기업들이 문화예술후원기관이 주체하는 행사에 적극적으로 직원을 참여시키는 것으로 나타났다. The creativity and innovation are the motive power for the business competitiveness in the modern industrial word, and they are able to be performed by the engraftation of culture and arts to the business management. Many enterprises are sponsoring the culture and arts as the social responsibility but they also are using these activities as the commercial strategy such as the improvement of image, sales promotion, customer acquisition, etc. rather than the simple donation. Moreover, these activities are currently used among the big size enterprises as the means for the employee motivation such as increase of job pride, identification among employees, improvement of job performance that will contribute to strengthening the management organization. The enterprise sponsorship of culture and arts brings the direct effects for the vitalization of culture and arts industry and also the indirect effects for the establishment of creative society. There are many culture and arts heritages in Germany to be maintained and developed, and so the German government actively supports the culture and arts, whereas the enterprises have the complementing roles. Besides the sponsorship of enterprise, the private foundations and civil organizations are supporting the culture and arts, and so the culture and arts industry largely contributes to the value add`s creation of German economy. The total sponsorship amounts of German enterprises are larger than of British enterprises, but lower than of enterprises in the U. S. A. where the cultural policy is focused on the market and the non governmental aspect. ``Social responsibility`` is the most frequent purpose among the sponsoring enterprises in German language countries, followed by ``commerce/communication`` and ``employee motivation``. The music related genres are the majority as the application of culture and arts in Korea, whereas the various genres such as paintings, music and etc are utilized in German language countries. The most German enterprises regard the geographical relationship as relevant independent of the enterprise size, and so prefer to sponsor the culture and arts in-stitutions in hometown and its environment. This trend can be interpreted as the win-win growth mind with the local area where the enterprise is located. The largest effect from the sponsorship is ``image increase``, followed by ``positive impact to the management structure``, ``win reputation``, ``identification among employees``, ``customer loyalty`` and ``brand image``. There is a high statistical significancy between the enterprise size and ``employee motivation``, also between it and ``identification among employee``. The enterprise internal effects from the sponsorship of culture and arts are proportional to the enterprise size. Many enterprises join the employee to the events and projects of the culture and arts institutions sponsored by them.

이정만 ( Jeong Man Lee ),박태준 ( Tae Jun Park ) 한국미용학회 2012 한국미용학회지 Vol.18 No.3

The objective of this study is to find out if the psychological experiences of incentive tourism do influence engagement and job performance at a cosmetic sales organization from the view point of culture marketing for internal customer. 112 sales people were surveyed who were working on incentive base and have participated in incentive tourism arranged by their company. The most preferred area for incentive tourism was Europe followed by North America. The most considered point for incentive tourism was tourism program followed by selecting the visiting nation. Emotion oriented experience and social oriented experience statistically influenced engagement of the sales organization, but physical oriented experience did not. Engagement also statistically did influence job performance. Emotion oriented experience, physical oriented experience and social oriented experience statistically did influence job performance. Tourism give us the chance not only for experiencing the local life style culture and natural resources, but also for experiencing their art works such as literature, architecture, music, paintings, clothes, foods and etc. These cultural experiences strengthen the ties among sales staffs, and furthermore their cultural level will increase so that their sales competitiveness to the customers will be higher. The incentive tourism will be a strategical choice for the service organization who wants to boost the loyalty and pride of the internal customers in order to increase their job performance.

중소기업경쟁력 향상을 위한 문화마케팅 고찰

이정만 ( Jeong Man Lee ),김형진 ( Hyung Jin Kim ) 한독경상학회 2011 經商論叢 Vol.29 No.4

본 논문은 기업의 문화마케팅 종류와 실태를 살펴보고, 이를 통한 기업경쟁력 향상을 모색하는 것을 목표로 한다. 기업 문화마케팅이론 및 사례를 분석하고 특별히 중소기업의 현실을 짚어봄으로써 중소기업의 문화마케팅이 촉진될 수 있는 정책적 제안을 제시하고자 한다. 소비자의 소득증대에 따라 재화와 서비스에 대한 경제적 패러다임이 변화하였다. 1980년 대 까지는 가격경쟁력을 갖춘 단순기능을 선호하였고, 1990년대는 고품질과 고기능제품을 선호하였다. 하지만 2000년대부터는 감성과 꿈을 체험할 수 있는 고 품격 가치를 지닌 재화와 서비스를 원한다. 오늘날과 같이 빠르게 변화하는 기업 환경 속에서 문화마케팅은 기업경쟁력 강화 수단으로 대두되고 있다. 문화마케팅을 실시함에 따라 내부적으로 조직원들의 유대강화, 직무 만족도 상승, 이직률의 감소 등의 생산성 향상과 기업 매력 도를 높이는 계기가 되어 우수한 인재를 영입할 수 있는 동기가 된다. 기업 외부적으로는 상품과 서비스에 문화 예술적 요소를 체 화 시켜 차별화된 이미지를 연출하고 공적 책임을 다하는 문화기업으로서 위상을 높일 수 있다. 문화마케팅을 실시하는 기업들은 매출성과에 기대하고 있지만 실질적으로는 종업원 조직 강화효과가 가장 큰 것으로 설문조사에서 나타나고 있다. 기업 문화마케팅 실시에 어려움이 큰 것은 재정적 문제였고, 그 다음은 실행방법에 대한 지식부족이었다. 문화마케팅은 많은 기업들에게 화두가 되고 있지만, 중소기업은 경영상 어려움과 인적 자원 부족으로 현실적으로 접목하기에는 많은 어려움이 있다. 이런 중소기업들을 위한 다양한 재정지원, 세제혜택, 문화마케팅 인증제도 등의 정책적 배려는 문화마케팅을 도입하는 기업뿐 아니라 문화예술 분야 발전에도 기여할 것이다. 문화예술의 발전은 기업 문화마케팅활용도 높일 수 있어 상생 발전구조를 이룰 수 있다. The object of this research is to survey the kinds and the real state of the Enterprises culture marketing and to find a way to improve its competitiveness. Especially, the reality and the culture marketing cases of the Small and Medium sized Enterprises (SME`s) will be analyzed to find the political proposal for them. The economic paradigm for product and service is changed according to the income increase. The simple functions with price competitiveness were preferred up to 80`s, the high specifications and functions were in 90`s, but consumers desire the product and service equipped with high cultural value giving sensitivity and dream from 2000`s. The culture marketing is becoming a tool to strengthen the competitiveness of Enterprise under the business environments very quickly changed. Carrying out the culture marketing will contribute to the productivity improvement through strengthening ties among members, increase of job satisfaction, decrease of job turnover and the rise of the Enterprise`s attractiveness resulted in a motivation to recruit the talented people. Enterprise externally, the differentiated images are created by embodiment of the culture and arts in product and service and its reputation rises as a cultural Enterprise completing the social responsibility. Empirical studies show the organizational effects are the most obvious result, even though the companies doing the culture marketing expected the increase of the sales volume. However, the financial deficit is the most severe difficulty followed by no knowledge of culture marketing ways, according to the survey among companies. The culture marketing becomes a conversation topic for Enterprises, but SME`s have a lot of difficulties to introduce the culture marketing. The political consideration such as the various financial supports, tax exemption benefits, certificate system of culture management might be incentive programs to introduce and to continue the culture marketing of SME`s and also will contribute to the development of the culture and arts area.

Fontan 수술을 받은 정신지체 소아에서 인상채득을 위해 시행한 깊은 진정

이정만,서광석,김현정,신순영,신터전,Lee, Jung-Man,Seo, Kwang-Suk,Kim, Hyun-Jeong,Shin, Soon-Young,Shin, Teo-Jeon 대한치과마취과학회 2012 Journal of Dental Anesthesia and Pain Medicine Vol.12 No.1

The Fontan operation is a heart operation used to treat complex congenital heart defects like tricuspid atresia, hypoplastic left heart syndrome, pulmonary atresia and single ventricle. A single ventricle is dedicated to pumping oxygenated blood to the systemic circulation and the entire systemic venous return reaches the pulmonary arterial system without the direct influence of a pumping chamber. In the patient with Fontan operation, it is important to achieve adequate pulmonary blood flow and cardiac output in anesthetic management. In this case, a 10-year-old boy (19.6 kg, 114 cm) with cleft palate, cerebral palsy and severe mental retardation, who underwent a Fontan operation when he was 4 years old, was presented for deep sedation. Because he was suffering from eating disorder with cleft palate, the orthodontist and the plastic surgeon planned to insert intraoral orthodontic device before cleft palate repair. But it was impossible to open his mouth for alginate impression procedure. After careful pre-anesthesia evaluation we planned to administer deep sedation with propofol infusion. After Intravenous catheter insertion, we started propofol intravenous infusion with the formula of a loading dose of 1.0 mg/kg followed by an infusion rate of 6.0 mg/kg/hr with syringe pump. His blood pressure was remained around 80/40 mmHg after loss of consciousness, but he could not maintain his airway patent. So we lowered the infusion rate to 3.0 mg/kg/hr, immediately. The oxygen saturation was maintained above 95% with nasal oxygen supply, and blood pressure was maintained around 100-80/60-40 mmHg. After the sedation of 110 minutes with propofol (the infusion rate to 3.0-5.0 mg/kg/hr), he fully regained consciousness, and was discharged without complication after 1 hour observation. In case of post-Fontan patient, intravenous deep sedation with propofol was safe and effective method of behavioral management during dental treatment.
