The purpose of this study was to identify appropriate sweeteners that could improve the dryness, while reducing calorie by adding various sweeteners to Sulgitteok using dry non-glutinous rice flour. Of six sweeteners (sucrose, trehalose, honey, acesulfame K, oligosaccharide, and erythritol) added, Sulgitteok with acesulfame K had the highest moisture content, whereas Sulgitteok with trehalose had the lowest moisture content. The moisture content of all samples were decreased when storage period was increased except the sample added with trehalose. Sulgitteok with erythritol had the highest L-value, whereas Sulgitteok with oligosaccharide had the lowest L-value. The L-value and b-value of Sulgitteok samples decreased when storage period was increased. Sulgitteok with trehalose had the highest hardness, whereas Sulgitteok with oligosaccharide had the lowest hardness. The hardness increased in all samples when storage period was increased. Sulgitteok sweetened with acesulfame K and honey had the highest acceptance.

The proposed technique uses cyclic frame structure, where three periods such as beacon period (BP), mesh contention access period (MCAP) and slotted period (SP) are in a data frame. This paper studies on a mechanism to allow communication nodes (6lowpan) in a PAN with different logical channel for global healthcare applications monitoring technology. The proposed super framework structure system has installed 6lowpan sensor nodes to communicate with each other. The basic idea is to time share logical channels to perform 6lowpan sensor node. The concept of 6lowpan sensor node and various biomedical sensors fixed on the patient BAN (Body Area Network) for monitoring health condition. In PAN (hospital area), has fixed gateways that received biomedical data from 6lowpan (patient). Each 6lowpan sensor node (patient) has IP-addresses that would be directly connected to the internet. With the help of IP-address service provider can recognize or analyze patient data from all over the globe by the internet service provider, with specific equipments i.e. cell phone, PDA, note book. The NS-2.33 result shows the performance of data transmission delay and data delivery ratio in the case of hop count in a PAN (Personal Area Networks).

Environmental factors such as soil moisture, land management, and weather conditions affecting Fusarium wilt of sweet potato were investigated in major sweet potato cultivation regions in Korea. Fusarium wilt occurred mainly in reclaimed terracing lands, which are flattened and located in hilly to mountainous areas at the base of the mountain, in early seasonal cultivation regions. Disease severity was lower in reclaimed fields with natural slope. The development of Fusarium wilt in the fields was highly correlated with precipitation during planting period (r=-0.96**). Fusarium wilt was more severe in fields with less than 20 cm of available soil depth than in fields with over 20 cm of available soil depth. Greenhouse studies were consistent with field studies that less soil moisture content caused severe Fusarium wilt of sweet potato. These results indicate that low rainfall and moisture of soil with low effective soil depth during planting period are important environmental factors influencing the development of Fusarium wilt.

Fragility as one of the most effective methods to evaluate seismic performance, which is greatly affected by damage index. Taking a multi span continuous rigid frame offshore bridge as an example. Based on fragility and reliability theory, considering coupling effect of time-varying durability damage of materials and time-varying attenuation effect of damage index to analyze seismic performance of offshore bridges. Results show that IDA curve considering time-varying damage index is obviously below that without considering; area enclosed by IDA of 1# pier and X-axis under No.1 earthquake considering this effect is 96% of that without considering. Area enclosed by damage index of 1# pier and X-axis under serious damage with considering time-varying damage index is 90% of that without considering in service period. Time-varying damage index has a greater impact on short pier when ground motion intensity is small, while it has a great impact on high pier when the intensity is large. The area enclosed by fragility of bridge system and X-axis under complete destruction considering time-varying damage index is 165% of that without considering when reach designed service life. Therefore, time-varying attenuation effect of damage index has a great impact on seismic performance of bridge in service period.

To determine the effects of ${\beta}$-carotene on the control of mastitis in dairy cows during the dry period, 38 dairy cows (18 mastitic cows and 20 healthy cows) were administered with 5 ml of ${\beta}$-carotene (30 mg/ml) intramuscularly twice (4 week intervals). Blood samples were taken from the cows before the injection and two weeks after the second injection, respectively, and were measured for the proportion of lymphocyte subpopulations and lymphocyte proliferation responses. With ${\beta}$-carotene injection, the proportion of cells expressing BoCD2, BoCD4 and B and N cells increased in healthy cows. In the presence of mitogens, lymphocytes from healthy cows showed significantly higher proliferation responses after ${\beta}$-carotene injection than before (p < 0.05), The somatic cell counts in ${\beta}$-carotene injected group decreased from 1,001,00 cells/ml at dry off to 647,000 cell/ml and 447 cells/ml at the stage of first and second weeks after calving, respectively (p < 0,05), This study indicated that ${\beta}$-carotene as a nonspecific immunostimulator could have a definite role for the prevention of intramammary infections in dairy cows at dry period.

The purpose of this study was to evaluate students' satisfaction with foodservice of middle school by region in Gangwon province. Students’ satisfaction concerning foodservice quality characteristics was surveyed by using importance performance analysis(IPA) technique in middle school foodsevice operations. Middle school students from four cities(Gangnung, Sokcho, Wonju, Chuncheon) were surveyed by self-developed questionnaire. Total of 1,025 questionnaires(female 521 and male 504 respectively) were analyzed using SAS program. The results of this study are summarized as follows: 1.The performance level of foodservice quality attributes was significantly different according to region. 2.The attribute of the highest performance level was taste of food. The attributes of the lower performance level were waiting time of meal service and treatment about complaints. The attributes of the higher importance level were hygiene of food and dining room and hygiene of spoon and cup and drinking water table. 3.Satisfied quality attributes identified were taste of food and variety of menu. Dissatisfied quality attribute identified was treatment about complaints. 4.The satisfaction of middle school lunch service was lower than their elementary school period. 5.The satisfied quality attributes of middle school foodservice were portion size, facility of dining room, hygiene of food, variety of menu compared with their elementary school period.

Purpose: Present study was designed to examine the casual relationships among service quality, self-efficacy, perceived usefulness, user satisfaction and Continuous Usage in new technology-based banking system. Also, we intended to testify the moderating effects of user experience period in causal model. We applied path analysis model in order to test the hypotheses and research model. Methods: Survey tool, that is, questionnaire has obtained validity through literature survey, exploratory survey and pretest and sample 279 was selected. For statistical treatment of pretest and main analysis, SPSS20.0 and AMOS 20.0 were employed and structural equation model was employed as analysis method. Results: Result of this study shows as follows. All factors have an effect on user satisfaction and Continuous Usage, and we found that user experience period played moderating effect in causal relationship. Therefore, new technology-based banking system is found that the determinants of continuous usage intention is different according to the user experience period. Conclusion: Present study shows that self-efficacy in via of user experience period, there is a need to emphasize that the main consideration factor new technology-based banking system. However, present study has some limitations to additionally research in the future.
