In many industries, the accurate and quick checking of goods in storage is of great importance. Most today's inventory checking is based on bar code scanning, but the relative position between a bar code and an optical scanner should be maintained in close distance and proper angle for the successful scanning. This requirement makes it difficult to fully automate the inventory information/control systems. The use of RFID technology can be a solution for overcoming this problem. The mobile robot presented in this paper is equipped with an RFID tag scanning system, that automates the otherwise manual or semi-automatic inventory checking process. We designed the robot system in a quite practical approach, and the developed system is close to the commercialization stage. In our experiments, the robot could collect information of goods stacked on shelves autonomously without any failure and maintain corresponding database while it navigated predefined paths between the shelves using vision.

Inventory inspection is an important task to eliminate the inconsistency between real assets and inventory management systems, and it is performed periodically at the site. In the case of a large-sized property, it is mainly managed in an outdoor workshop or a warehouse. However, due to the large area of the outdoor area, it is relatively difficult to identify the quantity and location of the property and is also vulnerable to theft. To solve this problem, we proposed a method and system for performing a warehouse inventory inspection using an unmanned aerial vehicle (UAV) and Bluetooth low energy (BLE) beacons. The proposed method has the following advantages. First of all, if we carry out inventory inspection by utilizing UAV, we can minimize user's effort compared to existing methods. The method of recognizing the asset by attaching the BLE beacon is more costly than using the existing RFID technology, but it is advantageous because the recognition distance is increased and the battery life of the tag is drastically increased. We also designed a BLE beacon reader for the system and implemented a prototype to show the feasibility of the proposed system. The prototype is based on Genuino 101, which is a kind of arduino, and adds HM-10 and Neo-6m modules to provide Bluetooth and GPS functions. The BLE beacon reader was tested in outdoor, and attached in drone. We also developed an inventory checking system based on the web to display results of inventory checking. The proposed approach enables the users to automate the operation of inventory checking on an outdoor warehouse.

We analyzed the effect of inventory pooling on the system where multiple depot was used to replenish retailers and where inventories are kept only on the depots. Inventory pooling consists of inventory integration and inventory exchange. We used simulation for checking the cost saving effect of reducing the number of depot (Inventory Integration) for the case when inventories kept on every depots are commonly used for all retailers when certain depot have stock out for their retailer assigned to them (Inventory Exchange) with the constraint of service level. Simulation on wide range of parameter settings results show that cost saving effect from inventory integration diminishes when transportation cost between depot and retailers or stock out cost, or retailer number increases. The effect becomes stronger when the demands on retailers have bigger variance or average. Also the results show that the cost saving effect from inventory exchange becomes stronger on the same situation when inventory integration effect becomes stronger.

The purpose of this study was to examine financial management practices in elementary school foodservices. Respondents were asked to provide information on demographics, operational characteristics, financial management activities(responsibility, importance and time demand). Data were collected from 106 elementary school foodservice using the mail questionnaire. The results were as follows 1. Time demand of 14 financial management activities was examined. The results of time-demand showed that most financial activities were performed about once per month. Reporting, inventory checking and production cost accounting were performed several times per week. 2. Major financial management activities performed by school dietitians were inventory checking, record keeping, production cost accounting, and foodservice operation planning. 3. Results of the importance rating of 14 financial management activities showed that the production cost accounting, budgeting, controlling meal costs, reporting the national treasury accounts, and inventory checking were rated as very important(4.00-4.49). Factor analysis was conducted on the importance ratings. Five activities were differentiated such as budgeting, record keeping, cost controlling, cost accounting, and reporting. The cost controlling task was identified at the most important one among them. 4. Important ratings for reporting were found to be significantly different by age, and years of experience. The younger and the less experienced were responded with higher scores on reporting. Analysis of variance for the importance scales by meal costs per one person, food cost percentage, labor cost percentage was conducted, but significant differences were not founded.

Purpose: The purpose of the study was to investigate psychological factors such as eating psychopathology, depression, and obsessive-compulsion that might influence self-harm behavior in patients with eating disorders. Methods: Patients with eating disorders (n=135) who visited "M" clinic for eating disorders participated in the study. Data were collected from March to August 2007 using the Eating Disorder Inventory-2, Beck Depression Inventory, Maudsley Obsessional-Compulsive Inventory, and Self-Harm Inventory (SHI). Results: The participants scored high on self-harm as well as on depression and obsessive-compulsion. On the SHI, a high frequency of self harm behavior such as 'torturing self with self-defeating thoughts', 'abused alcohol', 'hit self', and 'suicide attempt' were found for the participants. There were significant correlations between most eating psychopathology variables, depression, obsessive-compulsion, and self-harm behavior. 'Interoceptive awareness' (eating psychopathology), depression, and 'checking' (obsessive-compulsion) were significant predictors of self-harm behavior. Conclusion: Future interventions for patients with eating disorders should focus on assessing the possibility of self-harm and suicidal attempts, especially in those patients with high levels of eating psychopathology, depression, or obsessive-compulsion. Early intervention for depression and obsessive-compulsion could contribute to preventing self-harm and suicide in patients with eating disorders.

In Turkey, majority of industrial facilities are composed of precast buildings. However, precast buildings have suffered extensive damage during Kocaeli and Duzce (1999) and Adana-Ceyhan (1998) earthquakes. Therefore, in this study, fragilities of existing building stock and damage probabilities of precast buildings were studied. For this purpose, building inventories were prepared and variation of structural parameters was determined by investigating the design project of 65 precast buildings constructed in Denizli, Turkey. Twelve analysis models which reflect the stiffness, strength and ductility properties of building inventory were constructed. After the definition of strain based displacement limits and corresponding damage states for buildings, displacement demands were calculated by using non linear time history analysis. During the analyses 360 strong ground motion records were used. Exceedence ratios of concerned damage limits was calculated by checking the displacement demands and then PGV based fragility curves were constructed. Efficiency of strength, stiffness and ductility properties of existing precast buildings were investigated by comparing the fragility curves. The results have shown that the most effective parameters that govern the damage probabilities of precast buildings are stiffness and ductility. It was also stated that the results of fragility analysis and damage and failure observations performed after Kocaeli and Duzce Earthquakes are compatible.

Self-management training is one of the ways to empower patients to cope with disease. The aim of this before-and-after quasi-experimental study was to determine effects of a teach-back self-management training method on breast cancer patient happiness. Fifty breast cancer patients who visited the Park-e Neshat Limited Surgery Clinic in Kerman, Iran were randomly divided into intervention and control groups after convenience sampling and checking for inclusion eligibility. Data were collected using a demographic questionnaire and the Oxford Happiness Inventory before and after teach-back training and analyzed using SPSS 23. Findings showed no significant difference between mean happiness scores in the two groups before the intervention. However, after the intervention, the mean happiness score in the intervention group increased from 37.2 to 62.9, while it decreased from 41.4 to 29.8 in the control group. These changes were statistically significant (p<0.001). Even after controlling for the effect of confounding factors such as residence location and history of cancer education, the observed differences between the groups were statistically significant (p<0.001). A teach-back self-management training program can increase happiness levels in breast cancer patients. Therefore, the use of this method is recommended to improve self-management and increase happiness.
