In this paper, we introduced a POS(Point of Sale) system for a wallpaper company. We designed the database schema for the POS system, and proposed various application areas of the POS system. Especially, we discussed such application areas as inventory control, marketing, product development, and distribution channel. The quality of product management is enhanced by precise ABC inventory control and safety stock control. Marketing strategies can be more precisely established, and their effects can be measured. The development time can be shortened and new products can be developed based on the real market demands. Distributors can improve their management quality using precise sales data.

Objectives: We examined the prevalence of tobacco use and exposure to secondhand smoke among middle-school students in Korea using the Global Youth Tobacco Survey (GYTS) in 2013. Methods: The GYTS in Korea was conducted between July and August 2013 by the Korea Centers for Disease Control and Prevention. Data were collected using a self-administered anonymous questionnaire from a nationally representative sample of middle-school students aged 13-15 years in sampled classrooms. Results: The GYTS in Korea was completed by 4235 students aged 13-15 years in 43 middle schools. Approximately one in five of the students (17.8%) reported that they had tried cigarettes in the past, while 5.2% reported currently being cigarette smokers. Current cigarette smoking was higher in boys (7.5%) than in girls (2.6%). Of the students, 29.7% had been exposed to secondhand smoke at home, 47.4% inside enclosed public places, and 53.9% in outdoor public places. Of the current cigarette smokers, 25.7% bought their cigarettes from a store despite a law prohibiting this. Additionally, 58.0% of students noticed point-of-sale tobacco advertisements or promotions, 66.8% of current cigarette smokers wanted to stop smoking, and 70.9% of students had been taught about the dangers of tobacco use in school. Conclusions: These findings provide an opportunity to develop, implement, and evaluate a comprehensive tobacco control policy. The results suggest that youth have relatively easy access to cigarettes and are regularly exposed to secondhand smoke in public places, as well as to point-of-sale tobacco advertisements and promotions. Strict enforcement of the ban on tobacco sales to youth, expanding smoke-free areas, and advertising bans are needed to reduce tobacco use among youth.

외식업은 소비자의 수요가 많고 진입장벽이 낮아 창업이 활발하게 일어난다. 하지만 외식업은 폐업률이 높고, 프랜차이즈의 경우 동일 브랜드 내에서도 매출 편차가 크게 나타난다. 따라서 외식업 프랜차이즈의 폐업을 방지하기 위한 연구가 필요하다. 이를 위해, 본 연구에서는 프랜차이즈 가맹점 매출에 영향을 미치는 요인들을 살펴보고, 도출된 요인들에 머신러닝 기법을 활용하여 프랜차이즈의 성패를 예측하고자 한다. 강남구 프랜차이즈 매장의 PoS(Point of Sale) 데이터와 공공데이터를 활용하여 가맹점 매출에 영향을 미치는 여러 요인들을 추출하고, VIF(Variance Inflation Factor)를 활용하여 다중공산성을 제거하여 타당성 있는 변수 선택을 진행한 뒤, 머신러닝 기법 중 분류모델을 활용하여 프랜차이즈 매장의 성패 예측을 진행한다. 이를 통해 최고 정확도 0.92를 가진 프랜차이즈 성패 예측 모델을 제안한다.

This research is basically deals with an inventory distribution system with several regional sales branches. Under the continuous review policy, each sales branch places an order to its supplier whenever on hand plus on order inventory falls on the order point, and the order quantity is received after elapsing a certain lead time. This research first shows the method how to apply the product with low lever of demand into the continuous review policy. For the application, we use an order level as the maximum level of inventory during an order cycle. Also we analyze the lost sales case as a customer behavior. Further we use variable demands and variable lead times for more realistic situation. Based on the above circumstances, the research mainly discusses those methods to decide the optimal order level, order point, and order quantity for each sales branch which guarantees the system wide goal level of service, while keeping the minimum level of the system wide total inventory.

This paper deals with the economic analysis of domestic fuel cell vehicles considering subsidy and hydrogen price in 2015 and 2025. We selected TFCV (Tucson fuel cell vehicle) and TDV (Tucson diesel vehicle) to identify the economic feasibility of fuel cell vehicles compared with conventional internal combustion engine vehicles. We made some sensitivity analysis by changing input factors such as the size of the subsidy, the hydrogen price and the discount rate. Also, we made a break-even point analysis on hydrogen prices that equalize the economic feasibility of TFCV and TDV in 2025. As a result, TFCV is not economical in 2015 due to the relatively high prices of hydrogen and vehicles. If the sale prices of TFCV are 30,000,000 won and 35,000,000 won in 2025, then the break-even points of hydrogen prices are equal to 7,483 won/kg and 5,043 won/kg.

본 연구는 주택 후분양제도를 도입한지 6년여 기간이 경과되는 현 시점에서 제도시행의 취지 및 효과를 점검하고, 공급자 관점에서 분양시기에 따른 수익성 변화를 분석하여 그 정도를 파악하였다. 서울시 공동주택 사업을 대상으로 사례분석 하였으며, 분양수입의 현재가치분석, 민감도분석, 분양가를 예측한 현재가치분석을 실시하였다. 분석결과 첫째, 선분양제가 후분양제보다 5.1%~6.2% 수익성이 높았고, 선분양의 4가지 안(착공후 즉시, 건설공정 20%, 40%, 60%) 가운데 착공과 동시에 계약금을 회수하는 안의 분양수입이 가장 높았다. 둘째, 할인율 증가와 분양수입 감소는 정비례하였으며, 할인율이 커질수록 공급자관점에서의 분양수입은 감소하였다. 셋째, 분양시기에 따른 분양가격 변동을 감안하여, 기본형건축비의 변동폭을 고려한 분양수입의 현재가치는 선분양방식이 후분양방식에 비해 2% 내외의 미미한 수준에서 다소 높았다. 본 연구는 분양시기에 따른 수익성을 공급자 관점에서 명확하게 계량화하여 제시하였고, 분양시기 변화에 따른 분양가 변동을 고려하여 분양수입을 산출하였다는 점에 의의가 있다.

본 논문에서는 서비스업의 매장에 설치된 POS(Point of sale) 또는 Smart device를 이용하여 빈 방 또는 빈 테이블 등의 서비스 가능 공간 수에 따라 실시간으로 가격이 변동되는 시스템을 제안한다. 고객 입장에서는 보다 싼 가격으로 서비스를 이용할 수 있으며, 매장주 입장에서는 한산한 시간에 경쟁력 있는 가격으로 고객을 유치할 수 있도록 도움을 준다. 고객은 애플리케이션에 접속하여 위치기반서비스를 통해 이용하고자하는 서비스 매장을 선택하여 실시간으로 변동되는 서비스 가격을 확인할 수 있으며, 예약 및 결제를 한 후, 일정 시간 내에 해당 매장에 가서 서비스를 이용할 수 있다. 매장주는 POS 또는 Smart device를 통해 자동 또는 수동으로 서비스 가격을 변동시킬 수 있다.
