The purpose of this study was to analyze the amount of sugar from the afternoon snack menu of childcare facilities in Gyeongsangbuk-do. The amount of sugar was analyzed for afternoon snacks provided by childcare facilities between March and April 2016. The snacks provided were the same for processed and non-processed foods at 50.0% respectively. White milk accounted for the largest portion with 26.4%, followed by fruits with 19.9% and grains (sweet potatoes, rice cakes, etc.). It has been confirmed that the larger the facility, the lower the frequency of provision of non-processed foods, and the higher the provision of processed foods (p<0.05). Snacks served as non-processed foods showed the highest frequency of fruits and sweet potatoes. On the other hand, processed foods provided many sugar-rich products, such as liquid yogurt, hot cakes, and cereal, excluding white milk. The average sugar content was highest in processed milk products (13.9 g), followed by white milk (8.6 g), bread and snacks (8.0 g), other (4.6 g), and mixed grains (1.6 g). Of the total 216 snacks, banana flavored milk had the highest sugar content of 27.0 g, followed by strawberry milk (15.0 g) and castella (21.6 g). The findings are expected to be used as basic data for choosing the right snacks provided by childcare facilities and practicing reducing sugar intake.

Asynchronous transfer mode (ATM) provides the means to support with variety of multimedia serivices in broadband network. For the support of multimedia services, various data traffic with priortes should be controlled errectively and congestion function is required in the network to carry out the control operation. To accomplish this in a flexible and effective manner, priorty classes for the different services are commonly used. In this paper, we suggested a buffer managment algorithm in ATM network to improve overall network performance with separated buffer which consists of existing buffer with threshold andauxiliary buffer whose input consists of superposition of voice and data traffic. To evaluate the proposed buffer managment algorithms, simulations are excuted with two proiorities and the results are provied that network throughput is improved better than the existing parital buffer method.

Nowadays blogging is emerging as a new way of building human-to-human relationship by offering personal information and sharing opinions with others on their own initiatives. These blogging activities would be also useful when people are in a movement surrounding lots of objects, such as products and shops, which are potentially interesting to them. However, immediate response from the objects is not available using legacy blogging systems. This is mainly due to the segregation of the blogging content owners from the objects. This paper, hence, aims to propose a methodology which allows the users to directly communicate with the objects in a timely and context-aware manner, not the object owners, to get useful information or get served immediately. To do so, the concept of artificial bloggers which work on behalf of the objects and eventually the object owners is proposed. The functionalities of u-Blogging are also introduced with prototype system.

This study is conducted to investigate the factors affecting lumber conversion rate of sawmill industry in South Korea. Data were obtained from the survey of 38 sawmills in all geographic regions of South Korea. The variables examined in this study were region, softwood/hardwood log, domestic/imported/both log, the number of power-driven carriages (PDC) installed, the year when and country where PDCs was manufactured, the horse power of PDC, the number of labors required to operate each PDC, the sawing capacity of mill (mill size), and the types of major product and by-products. The lumber recovery factor (LRF) of sawmills were significantly influenced by the origin of logs, level of PDC automation, sawmill size, and size of logs (measured in diameter and length) while not by the location of the mill, types of major product and by-product, log species, and characteristics of PDC. Although these results provide useful information for understanding the technological characteristics of the Korean sawmill industry, further investigation with larger sample is necessary to reveal the more reliable characteristics of sawmill industry in South Korea.

System engineering(SE) management techniques applied for space launch system development are introduced to assess the current status and address the effwctiveness of these techniques. Management plans and guides are prepared for the work breakdown structure , data, comfiguration, interface control, Quality assurance, procurement, reliability, risk and verification/validation . Further improvement is required for the system engineering management plan(SEMP) to merge the international cooperation into current engineering managment system.

In this article, we consider a fourth order nonlinear difference system. By making use of the critical point theory, we obtain some new existence theorems of at least one periodic solution with minimal period. Our main approach used in this article is the variational technique and the Saddle Point Theorem.
