This paper presents a PCI (Peripheral Component Interconnect) controller embedded in a multimedia processor, called FLOVA (FLOating point VLIW Architecture), targeting for 3D graphics applications. Fast I/O interfaces are essential for multimedia processors which usually handle large amount of multimedia data. Therefore, in FLOVA, PCI bus is adopted for I/O interface due to fast burst transaction. However, there are several problems in implementation and verification to use burst transaction of PCI. It is difficult to handle data transaction between two units which have two different operating frequency. FLOVA has more higher operating frequency about 100MHz than that of PCI local bus and it makes lower utilization of FLOVA bus. Also, traditional simulation is not sufficient for verification of PCI functionality. In this paper, we propose buffering schemes to implement the PCI controller with wide bandwidth and high bus utilization. Also, this paper shows how to verify the PCI controller using real PCI bus environments before its fabrication.

This paper deals with storage and retrieval policies for S/R machine with capacity constraints in Man-On-Board AS/RS. It is assumed that storage sequence is based on SFC(spacefilling curve) routine and that storage layout is dedicated by storage policies. We present several heuristic algorithms for storage and retrieval policies which minimize total distance travelled by the S/R machine. These algorithms are based on COI, group COI, frequency of order, similarity between items and capacity of S/R machine. Experimental results of 24 combinastorial policies are provided to illustrate the performance of the heuristics under various rack utilization ratios. In storage policies, the results show that algorithms considering both similarity and frequency are better than those with COI as rack utilization is increasing. And algorithm using group COI is superior to others. In retrieval policies, the method with revision expression is shown to be better than others.

The objective of this study is to examine the association of social networks and medical care utilization of elderly living alone depending on self-rated health status, and also to measure the moderating effects of welfare services for elderly. To this purpose, the data which was collected from the 2014 National Survey on Elderly in Korea was analyzed by Chi-square test and Poisson regression. According to the results, social networks and elderly welfare services affected to medical care utilization of elderly living alone, only who aware of their self-rated health status as bad. With this group, the frequency of contact with family and participation in lifelong education had a significant effect on increasing medical care utilization. In contrast, the frequency of contact with neighbors and the participation in elderly employment program were significant to reduce the utilization of medical care. Furthermore, the moderating effects of elderly welfare services were also measured that formal social gathering has an effect of increasing the medical care utilization of elderly living alone by expansion of their social networks. Based on these results, this study consequently has an implication for suggesting expansion of elderly welfare services, which might be an alternative to social networks of elderly living alone, and also for seeking the direction of political intervention that helps health promotion and disease prevention through the research of medical care utilization.

Most agricultural reservoirs were built between the 1940s and 1970s. Therefore, it is necessary to evaluate the current water supply safety, considering changes in water capacity, the water management, and environment in relation to the passage of time.. The design frequency of drought, the number of years areservoir needs to be able to withstand a drought phenomenon, foragricultural water resources in Korea is the 10-year drought. As the water supply system and water supply patterns change, it is necessary to establish a concept of water supply reliability, which refers to the stability of water supply. This study evaluated the water supply reliability of agricultural reservoirs based on the designed frequency. The previously designed frequency and water balance analysis were used to calculate and analyze reservoir storage capacity, water supply turnover, water supply amount, water supply potential, water utilization safety, and water supply reliability. As a result, Yongmyeon Reservoir was found to be stable in terms of water supply reliability, whereas Seongho and Yongpung Reservoirs were found to be unstable using all methods. In particular, when converting the water utilization safety and the water supply reliability to the frequency of drought, Seongho and Yongpung Reservoir were in the lowest class, with a frequency of drought less than four years. Thus, we recommend that the consideration of water supply reliability be included in the preparation of adaptive measures and water supply strategies as changes in environmental conditions continue to develop.

Micronutrient malnutrition severely affects development and functioning of the body leading to increased morbidity and mortality. The study adopted a cross-sectional research design; cluster sampling was used to target 318 households. The significance level was P < 0.05, the mean age of primary food shoppers was 33 years and the average income was 3,000-5,000 Kenya shillings. Slightly above half, 55% of the primary food shoppers knew about fortification but only 25% understood its meaning. Fortified maize flour was consumed by < 80% of primary food shoppers however utilization frequency was low. In conclusion factors that were significantly associated with utilization of fortified maize flour included; knowledge on fortified maize flour (p=0.00), household size (p=0.005), preference of fortified maize flour (p=0.000) and level of fortification knowledge (p=0.002). Availability and price were ranked as the most important factors that influence utilization of fortified maize flour at 58% and 55% contrary nutritional value was ranked least important at 37%. The ministry of health and concerned millers should make more emphasis on creating and sustaining awareness more so a steady supply and affordable prices should be ensured by millers so that more primary food shoppers can be able to utilize the fortified maize flour.

The effect of feeding frequency on growth performance, body nutrient composition, and hematological parameters of juvenile chum salmon Oncorhynchus keta was investigated. The juveniles (10.9±0.3 g) were fed commercial feed for 30 days with feeding frequencies of 1, 2, 3, 4, or 5 meal (s)/day (n=2 tanks per treatment) in a recirculating aquaculture system (RAS). Fish were fed to satiation at each of the feeding frequencies. At the end of the feeding trial, final body weight, weight gain, and specific growth rate of fish fed 2 meals/day were significantly higher than those of fish fed 1 meal/day(P<0.05); however, no difference was detected among the other feeding frequencies. Daily feed intake significantly increased with increasing feeding frequency, whereas feed and protein utilization efficiencies continuously decreased with increase in the feeding frequency. Among the treatments, fish fed 1 meal/day showed the lowest value in whole-body lipid content and total protein concentration in plasma. Taken together, the optimal feeding frequency for growth performance and feed utilization efficiency in chum salmon juveniles reared in the RAS was determined to be 2 meals/day.
