Objectives: The purpose of this study is to identify the difference between the awareness and reuser rate of infection control t for disposable dental care supplies (DDCS) according to general characteristics and infection management-related characteristics. Methods: A questionnaire was used for 277 dental hygienists to check the general characteristics, infection management-related characteristics, awareness of infection control disposable dental care products, syringe needle, prophylaxis cup, prophylaxis brush, plastic saliva ejector, orthodontic bracket, and gloves reuse rate. Results: The awareness of infection control for DDCS differed according to 'hospital type', 'average number of patients per day', 'presence or absence of infection control guidelines', and 'experience in infection management training in the last two years' (p<0.05). Reuser rates of disposable dental care products differed according to 'hospital type', 'average number of patients per day', 'presence or absence of infection control guidelines', and 'experience in infection management training in the last two years' (p<0.05). Conclusions: In order to manage infection of DDCS, the level of infection control system in the workplace is improved and support for related education is needed. In addition, guidelines and regulations on prohibition of reuse and classification criteria for various DDCS should be prepared.

Efficient financial management is a critical factor in achieving school foodservice goals. The objective of this study was to suggest efficient financial management practices in secondary school foodservices. In pursuit of this objective, we first identified performance indexes for measuring the success of financial management. Second, we suggested financial management standards, financial data classification methods and a report system. Last, we analyzed operating ratios with the financial data of self-operated and contract-managed school food services. The data were collected through an open-ended questionnaire from 10 middle/high school foodservices in Seoul and Kyeonggi Provincial during on-sites visits and interviews with dieticians and managers. Student participation, sales goals, re-contract frequency and number and cost of disaster loss were identified as the performance indexes for financial management. Income statements were compiled by identifying and classifying financial data. Total revenues consisted of subsidies, meal sales, other revenue and interest. Expenditures consisted of purchased food, salaries and wages, utility costs, office supplies, kitchen supplies, purchased services, company overhead indirect costs, facility investment and maintenance, facility usage expenses, employee benefits and miscellaneous. Mean price of a meal was 2,326 won at self-operated foodservices when the subsidies were included as revenues and 2,360 won at contract-managed foodservices. When including the subsidies as revenues, the operating ratios of self-operated foodservice showed that the food cost percentage was 66.9％, labor cost 23.2％, operation cost 9.9％ and profit 0％. The correspond figures at contract-managed foodservices were 57.6％, 21.5％, 15.3％, and 5.5％, respectively. Food costs in self-operated foodservices was significantly higher than that for contract-managed foodservices, however, facility investment and maintenance and facility usage expenses at self-operated foodservices was significantly lower than those for contract-managed foodservices. Based on this study, the methodology and classification system of financial data was found to be applicable to assess the financial structure of school foodservices.

Objectives: To investigate the real-world re-use of disposable dental supplies (DDS) in dental offices and assess the relationship between general characteristics of dental hygienists and reuse of DDS, with respect to infection control characteristics. Methods: A questionnaire was administered to 277 dental hygienists to assess their general characteristics, awareness of infection control/DDS management, and re-use of DDS. Nine DDS were categorized into the following categories based on their purpose: Critical, Semicritical, Noncritical, and Personal protective equipment (PPE). The association between general characteristics of dental hygienists and re-use of DDS, with respect to infection control characteristics, was assessed using the chi-squared test. Results: All 9 DDS were re-used to different extents. The highest reuse rate of supplies were for masks (64.6%), prophylaxis cups (61.0%) and plastic saliva ejectors (30.0%). Overall, 89.5% of the participants re-used DDS; subgroup analysis showed the following proportions of specific DDS re-use: PPE 66.4%; Semicritical DDS 63.9%; Noncritical DDS 19.5%; and Critical DDS 1.8%. Based on the type of clinic, the rate of re-use was higher in dental clinics than dental hospitals. Thus, the re-use of DDS may be caused by inappropriate or nonexistent guidelines or habitual practice, rather than the awareness or attitude of dental hygienists. Conclusions: In order to ensure a safe environment within the dental clinic, DDS classifications must be clearly outlined in the dental infection control guidelines; moreover, additional studies are needed regarding the regulations for DDS re-use and disposal.

Medical services should be provided not only to patients but also to medical staff who are the main actors of medical treatment. This paper is based on Ethnography, observing the behavior of medical staff performing medical actions and finding what is the most frequent of physical medical treatment. In particular, I observed the need for recognition and performance of the clinical workforce for invasive medical treatment. Based on the Insight from the observation and analysis of medical staff's behavior on intravenous fluid therapy and in-depth interview, I defined four design value factors. Plus, I suggest a design prototype with a proposal for designing a medical consumable kit for intravenous fluid therapy to validate the design elements. Kitting medical consumables simplify the preparation and disposal process throughout the treatment, enabling rapid medical action and increasing work efficiency.

Busan Gimhae Airport is a major airline base in Busan Gyeongnam and is close to Busan Harbor, With close the five largest ports in the world, GimHae has not been developed to fit the size and role of the port. Currently, there is an increasing number of flights and airline companies in use, but it is already foreseen that the airport has become a saturating airport and a military airport. Therefore, the lack of awareness of the importance of GimHae Airport and the lack of routes for airlines are a problem for KimHae Airport. This study considers the reduction of logistics cost and time due to the expansion of the international airport by anticipating the development of Busan International Airport centered on the ship supplies logistics based on the present point of time and the development plan of Busan Kimhae Airport. In addition, we review the priority of major air routes based on prefabricated logistics, and examine the contributions to the port logistics industry in Busan.

The purpose of this study was to evaluate the actual state of middle and high school student's behavior about the use of oral hygiene devices for developing appropriate educational objectives to improve oral health. Data were collected by questionnaires from 445 middle and high school students in Jeolla-Bukdo, from April 20 to May 10, 2009. Surveyed data were analyzed by descriptive statistics, ${\chi}^2-test$ and t-test using SPSS V11.5 program. In the event of those who didn't use oral hygiene supplies, the largest group didn't use the devices since they didn't know about them well. Regarding links between experience of using oral hygiene devices and concern for oral health, those who received that education showed more interest in oral health, and the students who felt the need for that education had more interest than the others who didn't. The results of study suggest how to encourage students to utilize appropriate oral hygiene supplies and to help facilitate the development of school oral health education programs and the promotion of school oral health.

This study was conducted to investigate food purchasing management and the perception of school dietitians regarding food quality standards in the Chonbuk area of Korea. Self-administered questionnaires were collected from a total 205 dietitians and then evaluated using SPSS v. 11.5. The results are summarized as follows. Among the 205 school foodservice systems evaluated, 63.4% used a conventional system, while 36.6% were operated in a commissary manner. In addition, 64.9% of the schools had a menu cycle of 1 week (p<0.05) and 72.2% of the dietitians were responsible for the entire purchasing process (p<0.05). Moreover, a dietitian, school staff, foodservice staff, and parents participated in receiving and inspection of the food at 95.6% of the schools. Additionally, wholesalers and informal purchasing were preferred for purchasing food supplies. Moreover, 33.3% of dietitians in the commissary systems responded that they made Kimchi themselves instead of purchasing it (p<0.01). When the dietician's perception of food quality was evaluated, the average score was 3.33 based on a 5-point scale, although the scores differed significantly between dieticians working in conventional systems and those working in commissary systems (p<0.05). The scores for the quality standards related to the GMO agricultural and pesticide residues were the lowest. These findings indicate that it is necessary to develop standardized food quality and purchasing criteria and to provide education regarding these criteria to school dietitians to enable them to improve their knowledge regarding food quality standards and to implement effective purchasing programs.
