The purpose of this survey was to investigate the operation and the environment of foodservice in elementary schools nationwide. A questionnaire about foodservice management to practice and foodservice operation was mailed to dietitians of each school . Of the 1, 416 schools that participated in this survey, 388 schools were selected for analysis. The main results of this study are as follows. More schools in small cities . Education levels of dietitians were significantly different from area to area. Mean total length of employment for dietitians at school foodservice was 4.7 years and varied significantly by area and the type of foodservice system. Foodservice has been operated for 2-5 years in most of schools. Schools in large cities served more people than those in small cities and rural areas. Also , schools adapting conventional foodservice system served more people than those adapting commissary or joint management system. Foodservice expense also veried significantly by area and foodservice systems. Mean foodservice expense per meal were significantly higher in schools adapting commissary system than those adapting other systems. Most schools employed dietitians, cooks, and assistant cooks, but not engineers not drivers. Mothers of students were working voluntarily. The degree of participation by mothers in cooking , serving , and cleaning was higher in schools of small cities and rural areas than those in large cities, in schools adapting commissary or joint management system than those adapting conventional system. Education and training ranked as personnel management had one of the hardest tasks. Education and training of employees were also difficult for dietitians, especially in commissary or joint management systems. Percentage of schools having separate lunchroom was higher in small cities rural areas than in large cities, in joint management or commissary system than conventional system. Most difficult matters in serving was the portion control. Over 40% of schools did not use standard recipes. Menu cycles were shorter in schools in small cities and rural areas which adapted the joint management system than area other schools. Except refrigerators, thermos , display racks, sterilizers, sinks, worktables, and table, all other equipment were insufficient in most of schools. More than half of the schools didn't have rice cookers, flatware racks, and distributing carts which are stated plainly in detailed enforcement regulations for school foodservice. Cooking equipments were described as the most needed by dietians. According to the results of this survey, many and urgent problems need to be addressed improve the quality of school foodservice . Lunchroom setups, effective personnel management and expenses, recipes standardization, serving size control and regular checking and repairing of equipments are all problems to be addressed.

This paper presents the architecture and its function of Tool server. MPEG-21 will enable all-electronic creation, delivery and trade of digital multimedia content and transparent usage of various content types on network device. Therefore, we can provide access to information and services from almost anywhere at anytime with various terminals and networks. In order to support multimedia delivery chain that contains content creation, production, delivery and consumption, we need some elements to identify, describe, manage and protect the contents. Thus, we define Digital Item Processing(DIP), Digital Item Adaptation(DIA) server and Tool server as primary objects of MPEG-21 multimedia framework. DIP provides a function which creates and consumes Digital Item(DI) as a kind of a digital object by user. DIA server adapts the original DI to the usage environment description sent from the terminal and transmits the adapted DI to the terminal. Tool sewer searches for a tool requested from DIP or DIA and downloads the best tool to DIP or DIA server. In this paper, we present how Tool server is organized and is used among 2 primary objects. The paper is structured as following: Section 1 briefly describes why MPEG-21 is needed and what MPEG-21 wants. We see the basic architecture of tool server and its functionality by each module in section 2. Section 3 explains a scenario that tool server transmits tool to DIP or DIA. The paper concludes in section 4.
After TV Broadcasting service started, American Animation Industry changed dramatically. Through 1930th to 1940th, Major Animation Studios made every effort to adapt to new Animation production environment. Those efforts led rapid improvement of Animation again by succession of heritage in the golden age of American Animation. in spite of successful outcome, some critic like Bernard Oma blamed Animation on repeated chasing pattern, glamorized violence with exaggeration and humor caused by lack of idea. Nevertheless the decade passed by, achievement of the era still have influenced today. The animated films of the age have attractive power in comparison to today's works and Chuck Jones was a glamorous one of the age-leading masters. "Tom and Jerry" series, "Bugs Bunny", "Daffy Duck", and so on, he planned, designed characters and directed those masterpieces. In this study, episodes of "Tom and Jerry" that had been directed by Chuck Jones during 1963 and 1967 are analysed in the view point of direction style. In recently, Korean Animation Industry seems to be accumulated power for rising again by showing new animations that are adapted to new media. Thus, this study aims to give an idea for the new vision of Korean Animation through analysing Chuck Jones' Masterpieces.
Conventional construction technologies have been continually applied without consideration of its impact to the environment. This resulted to various problems including the negative responses of local citizens that regarded some constructed facilities as aversive facilities causing environmental and hydraulic problems in the urban area, etc. To prevent these problems, therefore, alternative methods should be undertaken. A new approach termed "Low Impact Development (LID)" technology is currently adapted in developed countries around the world. This study aims to investigate the efficiency of the developed small constructed wetland (SCW) with horizontal subsurface flow as a LID technique applicable in urban areas. Two test-bed facilities were constructed and monitoring had been conducted between July 2010 and June 2011. Based on the findings, the removal efficiencies achieved for TSS, $COD_{Cr}$, TN, TP, Total Fe, Total Pb for the SCW-1 were 66, 53, 46, 55, 67 and 50%, respectively. On the other hand, the SCW-2 attained 82, 62, 51, 48, 74 and 42% efficiency for TSS, $COD_{Cr}$, TN, TP, Total Fe, Total Pb, respectively. The results indicated that the removal of particulate matter and heavy metals which are considered as main pollutants from stormwater runoff in urban areas was satisfactory in the system. Therefore, the test-beds proved to be appropriate for the treatment of pollutants in urban landuses such as road, parking lot, etc. The results of this study can contribute to the conservation of aquatic ecosystems and restoration of natural water cycle in the urban areas.

The analog image based system consisted of a simulator and medical linear accelerator (LINAC) for radiotherapy was upgraded to digital medical image based system by exchanging the X-ray film with Computed Radiography (CR). With minimum equipments shift and similar treatment process, it was possible that the new digital image system was adapted by the users in short time. The film cassette and the film developer device were substituted with a CR cassette and a CR Reader, where the ViewBox was replaced with a small size PC and a monitor. The viewer software suitable for radiotherapy was developed to maximize the benefit of digital image, and as the result the convenience and the effectiveness was improved. It has two windows to display two different images in the same time and equipped various search capability, contouring, window leveling, image resizing, translation, rotation and registration functions. In order to avoid any discontinuance of the treatment while the transition to digital image, the film and the CR was used together for 1 week, and then the film developer was removed. Since then the CR System has been operated stably for 2 months, and the various requests from users have been reflected to improve the system.
This present study was investigated to elucidate degenerative changes according to the change of habitual environment on the myocytes of doves by restricting them from flight that is instinct behavior of this animal and strong exercise. To restrict doves from flight, they were confined in the cage (1 $m^3$) for 2 months. After this period, the myocardium of the experimental group was compared to that of wild doves in the ultrastructural and cytochemical ways. In addition, stereological changes were also examined. The results were as followings: 1. The body weight of the confined experimental groups was higher than that of the wild doves, but the ratios of the pectoral muscle/body weight (p<0.05) and the heart/body weight were lower. 2. At the ultrastructural level, the myocardium of confined doves appeared as wavy fibers in the smaller area than in the myocardium of wild doves. Also, the length of sarcomeres was longer in the confined doves. The number of sarcoplasmic reticulum and capillary was smaller in the myocardium of confined doves. 3. Cytochemical examinations showed that the activities of cytochrome oxidase were lowered in the confined doves. 4. Stereological analysis revealed that the density of myofibrils was greater in the confined doves. In contrast the volume density of sarcoplasmic reticulum (p<0.05) and the surface density of mitochondrial inner membrane (p<0.05) was lower in the confined doves, while the numerical density of mitochondrial inner membrane was higher (p<0.05). These results suggest that even the short period of restricted exercise can induce negative effects on the functions of myocytes of doves that are adapted for the strong exercise such as flight. Therefore, the maintenance of prolonged exercise seems to be one of the important factors that are critical to retain the functions of myocardium.

As the ARRA enacted recently in the United States, the interest in EHR systems have been increased in the field of medical industry. The passage of the ARRA presents a program that provides incentives to office-based physicians and hospitals adapting the EHR systems to guarantee interoperability with various medical standards. Thanks to the incentive program, a great number of EHR systems have been developed and lots of office-based physicians and hospitals have adapted the EHR systems certified by CCHIT. Keeping pace with the rapid changes in the market of healthcare, some enterprises try to push in to the United States healthcare market based on the experience acquired by developing EHR systems for hospitals in Korea. However, the developed system must be customized because of the different medical environment between Korea and the United States. In this paper, therefore, we design and develop an integrated EHR platform to guarantee the interoperability between different medical information systems based on medical standard technologies. In the developed platform, an integrated system has been composed by integrating various basic techniques such as data transmission standards and its methods, medical standard terminologies and its usage, and knowledge management for medical decision-making support. Moreover, medical data can be processed electronically by adapting an HL7 interface engine and the terminologies for exchanging medical information and the standardization of medical information. We develop SeniCare, an EHR system for supporting ambulatory care of the office-based physicians, based on the platform, and we verify the usability of the platform by confirming whether SeniCare satisfies the criteria of "meaningful use" issued by CMS or not.
As a first step towards identifying genes involving in the signal transduction pathways mediating rice blast resistance, we isolated 3 mutants lines that showed enhanced susceptibility to rice blast KJ105 (91-033) from a T-DNA insertion library of the japonica rice cultivar, Hwayeong. Since none of the susceptible phenotypes co-segregated with the T-DNA insertion we adapted a map-based cloning strategy to isolate the gene(s) responsible for the enhanced susceptibility of the Hwayeong mutants. A genetic mapping population was produced by crossing the resistant wild type Hwayeong with the susceptible cultivar, Nagdong. Chi-square analysis of the $F_2$ segregating population indicated that resistance in Hwayeong was controlled by a single major gene that we tentatively named Pi-hy. Randomly selected susceptible plants in the $F_2$ population were used to build an initial map of Pi-hy. The SSLP marker RM2265 on chromosome 2 was closely linked to resistance. High resolution mapping using 105 $F_2$ plants revealed that the resistance gene was tightly linked, or identical, to Pib, a resistance gene with a nucleotide binding sequence and leucine-rich repeats (NB-LRR) previously isolated. Sequence analysis of the Pib locus amplified from three susceptible mutants revealed lesions within this gene, demonstrating that the Pi-hy gene is Pib. The Pib mutations in 1D-22-10-13, 1D-54-16-8, and 1C-143-16-1 were, respectively, a missense mutation in the conserved NB domain 3, a nonsense mutation in the 5th LRR, and a nonsense mutation in the C terminus following the LRRs that causes a small deletion of the C terminus. These findings provide evidence that NB domain 3 and the C terminus are required for full activity of the plant R gene. They also suggest that alterations of the resistance gene can cause major differences in pathogen specificity by affecting interactions with an avirulence factor.

The irregularity of railway track affects not only the comfort of ride such as noise or vibration but also the safety of train operation. For this reason, it is an interesting research area to design a reliable and sustainable railway track system and to analyze the train movement mechanism based on systematic approaches considering reasons of track irregularity possible in a specific local environment. Irregularity data inspected by EM-120, an railway inspection system in Korea includes unavoidable incomplete and erratic information, so it is encountered lots of problem to analyse those data without appropriate pre-data-refining processes. In this research, for the efficient management and maintenance of railway system, progress rate of standard deviation of irregularity is quantified. During the computation, some important components of railways such as rail joint, ballast, roadbed, and fastener have been considered. Probabilistic distributions of irregularity growth with respect to time are computed to predict the remaining service life of railway track and to be adapted for the safety assessment.
Background: The safety of herbal products is an important issue in Korea. It is more complicated because of the concomitant use of conventional western drugs and herbal medicine, including prescribed medicine, folk herbs and food supplements. Although both western and traditional Korean medical doctors have studied on the safety of HMP, their results did not show relevant or consistent conclusions because of the poor quality of studies, including bias. Objectives: The aim of this study was to review the studies in Korea related to drug induced liver injury (DILI) systematically. We tried to estimate the proportion of causative materials of DILI and evaluate the clinical difference of DILIs from different materials. Methods: Systematic searches were performed on MedRIC and MEDLIS in Korea. The extraction of data as well as selective screening of the studies was carried out independently by two of the authors. There were no restrictions on the types of publication, including grey literature. Results: Twenty-one articles were included. Of them only 7 adapted prospective design and only 6 were published in peer-reviewed journals. The proportion of conventional drugs associated with hepatotoxic injuries in all DILI ranged from 15.8% to 83.3% and that of herbal medicine was from 28.9% to 44.7%. However, the criteria for herbal medicine were not clearly defined and concomitant medications were not fully investigated in most studies. There were limited objective data in the clinical differences of liver injuries from different materials and their results were conflicting. Conclusions: The causality assessments regarding DILI of herbal medicine were not performed properly and causative materials were misclassified in most of the studies published in Korea. These make the safety issue still ambiguous because of the limitations and lack of objectivity of the studies. More rigorous studies are required for clearly addressing these conflicting issues with cooperative investigation between traditional Korean and western medicine.
