  • Some multi echelon inventory systems carry perishable products. The value of these product reduces as the period of time they spend in the system. In this paper We derive the necessary condition to determine optimal quantity, service level for a perishable product. The systems considered consist of two echelons and carry single item. To determine the optimal order quantity, the demand is assumed to be constant, the holding costs may be different in the echelons, and it allows no shortages. I assumed the price of product decreases by negative exponential function. To determine service level, following assumptions used in the model ㆍlead time is constant. ㆍdemand is normal distribution. ㆍthe product starts to perish at the second echelon. Service level is computed for different levels of lead times and for different variance of demands and for different price functions. The experimental results indicate that the service level in cost is a function of service level in demand and perishability of product. Results of the models exhibit that perishability and the age of the product are critical to determine the lot sizing and service level.

  • This study aims to help improving the quality of military food service as identifying awareness, attitudes and satisfaction of cooking soldier on their duties and providing basic data to find out alternatives on the basis of identified data. The analysis results are described as follows. For general demographics of subjects, sergeants consisted of the highest percentage of population as 38.8% in terms of the rank. For educational background, the percentage of graduates or college students was 82.5%. For the characteristics of job performance of cooking soldier, those who studied entirely different courses from cookery and became to work as cooking soldier were 92(89.3%) of total subjects. For the question why they became to work as cooking soldier, the response that they didn't know the reason showed the highest percentage as 63.1%. Those who selected cooking soldier because they were interested in cookery were only 25.2%. And 94.2% of the population had no certificates related to cookery. With respect to awareness on training period to carry on duties as cooking soldier, 3 months were selected as the most appropriate period as 36.9%. In accordance with research on job percentage of cooking soldier, 'cleaning and washing' consisted of the highest percentage among ordinary duties as 16.8%, followed by 'cooking' as 12.3% and 'food dispensing' as 11.8%. This study suggests as follows on the basis of the results of this researches. Cooking soldier requires expertise, but the privates with short period of service are discharged from military service when they are accustomed to their duties and become experts. Accordingly, the cooking soldier system could not achieve more than its ordinary performance. Therefore, it is required to post non-commissioned officers who can serve for a long time as the special resources.

  • The greatest concern of vapor/gas respirators is when to exchange chemical cartridges, but it is very difficult to estimate the breakthrough time of them in the workplace spot due to so many factors influencing on breakthrough. There needs to study on estimating cartridge exchange period available practically in the spot, even if it is not precise. In the previous study, authors suggested the method on estimating service-life of chemical cartridges using cartridges discarded after use. This followed study was to estimate exchange period for chemical cartridges using comparison of concentrations between Korean Occupational Exposure Limits (KOELs) and odor thresholds of chemicals. Chemicals were divided into four groups, I, II, III and IV groups. Group I chemicals are relatively safe if cartridges are just or slightly delayed exchanged when smelling since odor thresholds were less than 0.5 times KOELs. Odor threshold of Group II chemicals are 0.5~2.0 times KOELs and potentially hazardous if cartridges are exchanged when smelling. Those chemicals should be conducted program on estimating service-life of cartridges, which was just previously published (J Kor Soc Occup Environ Hyg 2008;18(3) 204-215). Group III chemicals (odor thresholds are more than 2.0 times KOELs) and Group IV chemicals (odorless or no data for smelling) must be performed the above mentioned program before cartridges. Even if this method on cartridge exchange using odor threshold is practically widely used in the workplace spot in the present, program on estimating service-life of cartridges is recommended for all chemicals to reduce potentially hazards.

  • Recently, web-based service software has been used as to combine various information or to share information according to the needs of users and the convergence of specialized fields and individual dependent systems. According to the necessity of the user, the proper service environment and the selective service environment according to the purpose and the needs of the user have been studied in a variety of specialized and combined professional research fields and industries. Software based on cloud systems and web services is being used as a tool for appropriate group and user groups and roles. A service system combined dynamically needs a module to manage a user through internal logic and grant a service access authentication. Therefore, it has been considered various approaches that a user who accesses the system is given a service access authority for a certain period of time. Also, when the deadline is over, the authority that you are given to access system will go through the process of expire the right. In this paper, we define the roles of users who access web services, manage user rights according to each role, and provide appropriate service resources to users according to their rights and session information. We analyzed the procedure of constructing the algorithm for the service according to the procedure of each user accessing the web service, granting the service resource and constructing a new role.
