The operation of vending machine system presents a decision-making problem which consists of determining the product allocation to vending-machine storage compartments, replenishment intervals of vending machines, and vehicle routes, all of which have critical effects on system profit. Especially, it becomes more difficult to determine the operation variables optimally when demand for a product that is out-of-stock spills over to another product or is lost. In this paper, we propose a heuristic for solving the operation problem of the vending machine system and evaluate it by comparing with Yang’s algorithm on various test problems with respect to system profit via a computer simulation. The results of computational experiments show a substantial profit increase of the proposed heuristic over Yang’s algorithm. Sensitivity analysis indicates that some input variables impact the profit increase significantly.

Objectives : To estimate the economic burden of osteoporotic vertebral fracture (VF) from a societal perspective. Methods : From 2002 to 2004, we identified all National Health Insurance claims records for women ${\geq}50$ years old with a diagnosis of VF. The first 6-months was defined as a "clearance period," such that patients were considered as incident cases if their first claim of fracture was recorded after June 30, 2002. We only included patients with ${\geq}$ one claim of a diagnosis of, or prescription for, osteoporosis over 3 years. For each patient, we cumulated the claims amount for the first visit and for the follow-up treatments for 1 year. The hospital charge data from 4 hospitals were investigated to measure the proportion of the non-covered services. Face-to-face interviews were conducted with 106 patients from the 4 study sites to measure the out-of-pocket spending outside of hospitals. Results : During 2.5 years, 131,453 VF patients were identified. The patients had an average of 3.38 visits, 0.40 admissions and 6.36 inpatient days. The per capita cost was 1,909,690 Won: 71.5% for direct medical costs, 20.6% for direct non-medical costs and 7.9% for indirect costs. The per capita cost increased with increasing age: 1,848,078 Won for those aged 50-64, 2,084,846 Won for 65-74, 2,129,530 Won for 75-84and 2,121,492 Won for those above 84. Conclusions : Exploring the economic burden of osteoporotic VF is expected to motivate to adopt effective treatment options for osteoporosis in order to prevent the incidence of fracture and the consequent costs.

The purpose of this study was to evaluate the bone age and hand anomaly in Down syndrome patients. We reviewed radiographs in 52 children and youths with Down syndrome, aged from 2 to 23 years. The characteristic findings of hand anomaly were observed in the middle phalanx of the fifth finger, with the following incidence; brachymesophalangia(44%), clinodactyly(48%), and dysmesophalangia(15%). Pseudoepiphysis(21%) was found typically at the distal end of the first metacarpal bone and proximal end of the second metacarpal bone. Up to 8.5 years of age, bone maturation was retarded and thereafter bone age accelarated in advance of chronologic age. These findings may provide valuable information relative to the diagnosis and treatment of hand anomaly in Down syndrome.

Differentiated On Off line channel strategies are getting more attention due to conflicts between Off line channel and active E commerce. Choosing an appropriate channel strategy can prevent apparel products from clashing in market and manage each channel more efficiently. In fashion industry, product prices are flexible because of the short product life cycle and different distribution channels. It is essential to understand consumers’ apparel price cue perception when purchasing apparel in both On line and Off line. The objectives of this study was to examine the effects of apparel price cues on perceived savings and purchase intention in On line versus Off line retail channel. 303 quetionnaires from internet experienced women were used for the data analysis. Statistical analyses employed in this study were descriptive statistics, reliabilities conjoint analysis and regression. Overall, the perceived importance of apparel price cues were different between On line and Off line channels and each apparel price cue affected perceived savings and purchase intention differently according to distribution channels. Therefore, by considering characteristics of apparel price cue in On line versus Off line channels, differentiated channel strategies should be imposed to implement more effective marketing strategies.

This study evaluated the compression force at the L5/S1 disc using back strength and IEMG(Integrated Electromyography). We divided the distance into one-half, three-fourth and full, measured the back strength. The results showed significant difference much among the cases. IEMG values were analyzed under the condition of fixed vertical factor, two horizontal factors, and 2 times per minute for the stoop posture, As the result, there are significant differences between horizontal distance 35cm and 55cm. This result showed that back strength decreased and the motor units of erector spinae muscle increased as the horizontal distance increased. Therefore, decreasing the horizontal distance to decrease compression force at L5/S1 is important on preventing a low back pain. Also. by using these data for prediction musculoskeletal disorders if we design equipment, machine and apparatus for human welfare, we can give advantage of prevention of low back pain much. We will be able to apply these data to work method or workplace lay-out.

넓은 온도범위에 따른 정확한 열역학적 물성치들은 연소나 Rocket propulsion등 반응 메카니즘을 이해하기 위해서 기본적으로 필요하다. Benson's group additivity method는 기체상분자들과 라디칼의 엔탈피, 엔트로피, 열용량을 평가하는 방법이다. 본 연구의 목적은 문헌치를 이용할 수 없는 종류들의 열역학적 물성치들을 평가하는 것이다. Benson's method에 의한 computer code인 THERM 을 이용해 PAHs 와 할로겐 화합물의 열역학적 물성치들을 평가해 보았다. PAH's와 할로겐 화합물의 엔탈피를 문헌치와 비교해 본 결과 문헌치와 평가치와의 편차는 클로로벤젠 0.0KJ/mol에서 Pyrene 15.11KJ/mol의 범위를 나타내었으며, 평가오차는 0.0%에서 7.0%의 범위를 나타낸다. 또한 온도에 따른 반응열, 엔트로피변화량, Gibbs 자유에너지와 평형상수를 계산했다. Accurate thermodynamic property data over a wide temperature range is required to know detailed reaction mechanisms in combustion, rocket propulsion, and so on. Benson's group additivity method is an accurate method for the estimation of ideal gas phase enthalpies, entropies and heat capacities of molecules and radicals. The purpose of this study is to estimate thermodynamic properties for species which are not available in literature. The thermodynamic properties(enthalpy, entropy, heat capacity) of PAHs and halogen compounds are estimated by THERM based on Benson's group additivity method. Enthalpies(H) for PAHs and halogen compounds are compared with literature values obtained from various sources. Deviations between literature values and estimates range from 0.0 KJ/mol for chlorobenzene to 15.11 KJ/mol for pyene and % errors do from 0.0% to 7.0%. In addition, heat of reation, entropy change, Gibbs free energy change, and equilibrium constant are calculated as functions of temperature.

The skin of abdominal wall homografted t the back of rats and observed the morphological changes of grafted tissues and mother tissues on the 1 day, 1 week & 2 weeks after operation. For light microscopic observation, the tissues were fixed within 10% neutral buffered formalin solution and stained with routine hematoxylin & eosin and alcian blue-safranin. The results were as follows; 1. The grafted abdominal skin were degenerated markedly on 1 day after operation but some cells near hair follicle remained alive. 2. In the grafted skin, the epidermis was formed newly at the upper part of muscle layer on 1 weeks after operation. 3. The epidermis of grafted skin was thicker than mother skin on 2 weeks after operation, and there were many small cells having long nucleus arranged vertically to the basal lamina. 4. Few mast cells were found in the lower portion of muscle layer on 1 day after graft operation, but the mast cells which contain heparin mainly increased in number gradually from 1 weeks to 2 weeks after operation.
