  • Puerarin (P), an isoflavone derived from kudzu roots, has strong biological activities, but its bioavailability is often limited by its low water solubility. To increase its solubility, P was glucosylated by three dextransucrases from Leuconostoc or Streptococcus species. Leuconostoc lactis EG001 dextransucrase exhibited the highest productivity of puerarin glucosides (P-Gs) among the three tested enzymes, and it primarily produced two P-Gs with a 53% yield. Their structures were identified as ${\alpha}$-$_D$-glucosyl-($1{\rightarrow}6$)-P (P-G) by using LC-MS or $^1H$- or $^{13}C$-NMR spectroscopies and ${\alpha}$-$_D$-isomaltosyl-($1{\rightarrow}6$)-P (P-IG2) by using specific enzymatic hydrolysis, and their solubilities were 15- and 202-fold higher than that of P, respectively. P-G and P-IG2 are easily applicable in the food and pharmaceutical industries as alternative functional materials.

  • The target costing technique, mathematically discussed by Sauers, only uses the $C_p index along with Taguchi loss function and $\bar{X}$-P control charts to setup goal control limits. The new specification limits derived from Taguchi loss function is linked through the $C_p value to $\bar{X}$-P control charts to obtain goal control limits. Studies have shown that the point estimator of the $C_p index, $C_p, could vary from time to time due to the sampling error. The suggested approach is to use confidence intervals, especially the lower confidence intervals, to replace the point estimator. Therefore, an improvement on target costing technique is presented by applying the lower confidence interval of the $C_p index and using both Taguchi and Spiring's loss functions together with $\bar{X}$-P charts to make this technique more robust in practice. An example is also provided to illustrate how the improved target costing technique works.

  • The purpose of this study was to investigate the weight control attempts and related factors among 220 female college students in Seoul. Factors examined included body image, body satisfaction, interest in weight control, beliefs related to weight control, social norms, social expectations regarding subjects' body size and weight change. Data were analyzed using t-test and chi-square test(at $\alpha$=0.05). The average height and weight of subjects were 160.7cm, 52.2kg respectively. BMI and body fat(%) were 20.2 and 25.2%, respectively. One hundred seventy two students(78.2%) had attempted to control their weight, mainly to lose weight, and were categorized as the weight control attempt group. Subjects used diet modification as well as unhealthy method to control weight. 48.2% in the attempt group were underweight or normal weight(by BMI), suggesting that their weight control attempts were was unnecessary. Students in the attempt group described their own size as heavier than those in the no-attempt group(p<0.01) or other girls of their age(p<0.05) ; more dissatisfied with their body size(p<0.01), and showed more interest in weight control(p<0.01). Several differences in beliefs were also noted(p<0.001). The attempt group believed less strongly in the harmful effects or difficulties in weight control and believed more strongly in the advantages of weight control. With respect to social factors, the attempt group perceived that their family and friends wanted them to be smaller than they were(p<0.001), perceived that significant others felt that they should lose weight(p<0.05). These results suggest that educational programs for college female students should start focusing on the harmful effects of excessive dieting and information about desirable weight control methods. Students should be helped to have a correct body image. In addition, educational programs should incorporate strategies to change beliefs regarding weight control, as well as modifying social expectations from significant others.

  • Purpose: The aim of this study was to research caregiver trainees, and to understand the degree of subjective quality of life and internal and external locus control, and to examine the relationships between these variables. Method: The subjects of the research were 348 trainees at a Jeonju city caregiver training center. The subjective quality of life and the characteristics of locus control were used as measuring tools. The collected data was analyzed by the SAS 9.1 program. Result: The degree of subjective quality of life was significantly different according to the general characteristics of age (F=2.83, p=0.02), marital status (F=3.34, p=0.01), and willingness to work (F=3.94, p=0.05). The degree of internal locus control was significantly different according to the general characteristic of marital status (F=3.0 p=0.01). External locus control was significantly different according to the general characteristics of age (F=9.77, p=0.00), occupation (F=2.91, p=0.01), educational level (F=9.65, p=0.00), monthly income (F=3.81, p=0.00), educational institution (F=2.06, p=0.04), educational experience (F=4.15, p=0.00), and subjects willingness to work (t=8.71, p=0.00). A significant correlation was identified between the subjective quality of life and internal locus control (r=0.23, p=0.0001). Conclusion: A significant correlation was shown between subjective quality of life and internal locus control of the caregiver trainees.

  • Regarding the fattening of younger cattle that the Ministry of Agriculture Forestry and Fisheries (MAFF) recommends in Japan, this study looked at vitamin A control in feed and blood and its effect on performance of production and carcass composition of Wagyu steers. Five sets from 10 Wagyu artificial identical twins were divided to into 2 groups, a restricted group (Test) and a supplied group (Control). The body weight at the finishing time of the Test was significantly lower than that of the Control (p<0.05). The daily gain from 13 to 21 months old, as the animals in the Test were fed the concentrated feed without Vitamin A, was significantly different (p<0.05) between the Test and the Control. The total daily gains for the Test and the Control for the fattening period were 0.82 kg/day and 0.93 kg/day, respectively, which showed a significant difference (p<0.01). Regarding the rib thickness, the Test was thinner than the Control. The Beef Marbling Scores of the Test and Control were 3.60 and 2.80, respectively. The muscle weight of the Test was significantly smaller than that of the Control (p<0.01). However, regarding the ratio to the carcass, the Test was significantly higher than the Control (p<0.05). For the fat weight, the Test was smaller by about 15 kg than the Control (p<0.01). Furthermore, for the fat ratio to the carcass, the Test was significantly lower than the Control (p<0.05). The bone weights of the two groups were approximately the same. Regarding the ratio of bone to carcass, the Test was higher than the Control (p<0.01). For the younger fattening method, the low level vitamin A in the serum had the effect that the muscle ratio to the carcass weight was greater and the fat was less, but the carcass and muscle weight were less.

  • Majority of the imported malaria cases in Korea is attributed to Plasmodium falciparum and P. vivax infections, whereas P. malariae and P. ovale infections are very rare. Falciparum and ovale malaria are mostly imported from Africa, while most of the vivax malaria cases are imported from Southeast Asia. Here, we report 6 Korean imported ovale malaria cases (4 males and 2 females) who had visited in Africa during 2013-2016. These subjects were diagnosed with P. ovale based on microscopic findings, Plasmodium species-specific nested-PCR, and phylogenetic clade using 18S rRNA gene sequences. We identified 2 P. ovale subtypes, 1 P. ovale curtisi (classic type) and 5 P. ovale wallikeri (variant type). All patients were treated with chloroquine and primaquine, and no relapse or recrudescence was reported for 1 year after treatment. With increase of travelers to the countries where existing Plasmodium species, the risk of Plasmodium infection is also increasing. Molecular monitoring for imported malaria parasites should be rigorously and continuously performed to enable diagnosis and certification of Plasmodium spp.

  • This paper demonstrates the benefit of using MOOS-IvP in the development of control system for Unmanned Underwater Vehicles(UUV). The demand for autonomy in UUVs has significantly increased due to the complexity in missions to be performed. Furthermore, the increased number of sensors and actuators that are interconnected through a network has introduced a need for a middleware platform for UUVs. In this context, MOOS-IvP, which is an open source software architecture, has been developed by several researchers from MIT, Oxford University, and NUWC. The MOOS software is a communication middleware based on the publish-subscribe architecture allowing each application to communicate through a MOOS database. The IvP Helm, which is one of the MOOS modules, publishes vehicle commands using multi-objective optimization in order to implement autonomous decision making. This paper explores the benefit of MOOS-IvP in the development of control software for UUVs by using a case study with an auto depth control system based on self-organizing fuzzy logic control. The simulation results show that the design and verification of UUV control software based on MOOS-IvP can be carried out quickly and efficiently thanks to the reuse of source codes, modular-based architecture, and the high level of scalability.

  • The effects of the mouth care using cool sterile normal saline on oral stomatitis were investigated in 59 patients on chemotherapy. The subjects were divided into two groups, one was experimental group(N=31) in which the subjects were provided mouth care 4 times a day (after meals, before bedtime)with cool normal saline, the other was the control group(N=28), The Oral Assessment Guide(OAG) which it includes eight items(voice, swallowing, lips, tongue, salivation, oral mucous membrane, gingiva & teeth) was used to assess oral status six times(once in the Prechernotherapy Period, and on the third, 5th, 7th, 10th & 14th day postchemotherapy). The means of the total scores at each time were analyzed by repeated ANOVA The results are as follows : 1. The incidence of stomatitis was higher in the control group than in experimental group. The incidence of third grade stomatitis characterized by bleeding, sore, infection & severe pain was 3.3% in the experimental group, and while 21.4% in the control group(p=0.01). 2. The number of stomatitis sites which were occurred in the experimental group were significantly lower than in the control group(p=0.046). 3. The grade of stomatitis(mean of total score) for patients in the control group was significantly higher than for patients in the experimental group (p=0.005). 4. In the control group, voice change increased in the period between the seventh and tenth day after chemotherapy (p=0.04). 5. In the control group, swallowing difficulty was mest severe in the period between seventh and tenth day(p=0.05), and decreased by the fourteenth day(p=0.01). 6. Changes in the lips gradually increased after chemotherapy in the control group(p=0.0025), while they were significantly lower in the experimental group(p=0.0002). 7. The increment of tongue changes started on the third day after chemotherapy reached a peak on the tenth day and decreased by the fourteenth day in both groups(p=0.0016). 8. Driness of the mouth reached a peak on the seventh day after chemotherapy in the control group (p=0.05). 9. The degree of oral mucositis was significantly higher in the control group than in the experimental group(p=0.02) . In the control group, the mucosal change started three days after chemotherapy and reached a peak on the tenth day(p=0.03). 10. Changes in the gingia were significantly higher in the control group(p=0.03). In control group, the degree of gingivitis reached a peak on the tenth day. In conclusion, meuth care with normal saline four times a day could reduce the incidence and grade of stomatitis. Stomatitis was shown to begin on the third day after chemetherapy, reach a peak on the tenth day and be reduced by fourteenth day.
