  • The aim of this study was to develop the tartary buckwheat (Fagopyrum tataricum Gaertn.) sprouts and to clarify the biological and chemical characteristics of the sprouts. At 7 days after seeding, hypocotyls length and thickness, and root length of tartary buckwheat sprouts were 137 cm, 1.4 mm, and 12.6 cm, respectively. Fresh weight, dry weight, and moisture contents of an individual sprout at 7 days after seeding were 202 mg, 5.4 mg, and 95.3%, respectively. Protein content in tartary buckwheat sprouts was 23.0% which relatively higher than that of seeds, while lipid and ash contents were 3.5% and 5.3%. Among 7 minerals, the content of phosphorus showed the highest level (1,383.5 mg/100 g), while the contents of sodium and potassium were 1,197.5 mg/100 g and 1,106 mg/100 g, respectively. The contents of other minerals were Mg (795.5 mg/100 g), Ca (149 mg/100 g), Zn (16.4 mg/ 100 g), and Fe (14.7 mg/100 g). The rutin content of tatary buckwheat sprouts including root parts was the highest (5644.9 mg/100 g) at 7 days after seeding. The concentration of catechin derivatives in tartary buckwheat sprouts was high in order of catechin (59 mg/100 g), epicatechin gallate (47 mg/100 g), and epicatechin (14 mg/100 g).

  • Korea and China are two opposite countries located aside Yellow Sea and co-utilize the East China Sea. The two countries are close together from geological point of view, however, the competitive development of resources was more emphasized than the cooperative development of resources between the two countries because the special policy relationship. Additionally, after the communist government of China was founded in 1949, the political conception between the two countries was quite different. Therefore the establishment of appropriate international fisheries co-operation was impossible, and the international management problems of fisheries resources in Yellow Sea and East China Sea were let alone. UN convention on the Law of the Sea came to force in 1994, Korea and China adopted the exclusive economic zone system in 1996. On the other hand, Fisheries Law in Korea was enacted in 1953 in order to management of fisheries resources, and also China was enacted fisheries law in 1986. The two countries control the fisheries effort through fisheries license system, meanwhile through prohibition fishing area, prohibition fishing period, limitation of net size, and limitation of body length to conserve and manage the fisheries resource. The serious management methods of resource management in the two countries are similar such as the creation of promptly decreased species and those species that have commercial value, discharge of fish seedling stock, settlement of artificial reef and clean of fishing ground. Therefore, the two countries should consider not only the improvement of formal law system, but also how to recover the fisheries resources in circumference water zone and how to improve the efficiency of fisheries resource management. Specially the settlement and management of artificial reef should be chosen in the area that have the highest benefit to two countries, and should establish the common management system of discharge of fish seedling stock. And the two countries should adopt the same criteria through technical management and limitation of net size, limitation of body length, and prohibition area of special fisheries to ensure the highest fisheries benefit of fisherman in the two countries and the highest efficiency of fisheries resource management.

  • In this study, we examined the changes of fruit number and fruit weight according to the length of bearing branch of Actinidia arguta and identified the correlation the length of bearing branch and fruit characteristics. The fruit weight and the fruit number of A. arguta bearing branch which length are below 15 cm and over 30 cm were 11.7 g, 4.3 and 12.3 g, 13.8, respectively. From the results, the bearing brach which length was below 15 cm must be removed in winter season pruning. The pruning experiment was conducted to examine the effects on fruit quality and yield of A. arguta. Total fruit yield of heavy-pruning was $14.3{\pm}1.5kg/tree$. The production of fruits over 15 g wight was $8.2{\pm}0.9kg/tree$, that of fruits between 10 g to 15 g was $4.0{\pm}0.7kg/tree$, and that of fruit below 10 g was $2.1{\pm}0.3kg/tree$, respectively. Average fruit yield of nonpruning was $26.7{\pm}2.1kg/tree$, fruit yield over 15 g, between 10 g and 15 g, and below 10 g were $2.5{\pm}0.5kg/tree$, $19.2{\pm}1.4kg/tree$, and $5.0{\pm}0.6kg/tree$, respectively. Distribution of high quality fruit (over 15 g) showed that non-pruning was almost 15~16 g but pruning was evenly distributed between 15 g and 20 g. According to the survey, The high quality fruit (over 15 g) would not be harvested if the winter pruning is not applied in the A. arguta cultivation.

  • This study carried out an experiment to find out the reaction of hairtail, Trichinus lepturus to the colors of LED light as a basic study on the development of the trolling gear and a method to enable the day-night operation. We used hairtails caught around Seongsan-po, Jeju Island by set nets and hairtail angling. The seven hairtails of the average length 68.9 cm (SD 9.2 cm) and the average weight 135.9 g (SD 47.9 g) were adapted themselves in the experimental water tank, 15 m Self-Governing 1.7 m in height and 1.5 m in depth, and then they were studied. We conducted experiment at the Ocean and Fisheries Research Institute in Jeju Special Self-Governing Province, from November to December 2015, and the sea surface temperature was between 16.5 and $19.5^{\circ}C$. The four colors of LED light, blue, white, green and red, were set up to transmit downward from the marginal area of tank. The 1 meter depth light intensity of LED colors is as follows: $0.09w/m^2/s$ (blue), $0.18w/m^2/s$ (white), $0.04w/m^2/s$ (green) and $0.007w/m^2/s$(red) To know the optimum LED color light, we selected one with better reaction rate after comparison of two colors simultaneously and the selected color was again compared to the other color in a tournament style two times a day (day and night) and ten times totally. The reaction rates were shown as the frequencies of hairtail appearance for 5 minutes in the lighting zone after turning on the LED lights. The reaction rate of the blue was at 97% unlike the red 3% (p < 0.001). The blue was at 75% unlike the green at 25% (p < 0.001). The blue was at 67% unlike the white at 33% (p < 0.001). Therefore, the color of light source showing the highest reaction rate was the blue.

  • The purpose of this study was to identify the differences of older adults' perceptions of foodservice quality attributes of current offerings in Continuing Care Retirement Communities (CCRCs) in terms of their lifestyles (length of residency, special diet, housing option, travel frequency, dine out frequency), dining frequency, and demographics in the dining room of CCRCs. The survey was administered to residents in three CCRCs. Data was analyzed for 140 surveys using t-test, ANOVA, and factor analysis. This study found female older adults perceived the following attributes were more important than male ones: presentation of food, color and garnish, texture of vegetables, taste and flavor of food, and respectful attitude of serving staff. Older adults who have a special diet perceived the seasoning and bite sized pieces were more important than those who have a general diet. Also, there were significant differences between frequent visitors and occasional visitors in the dining room of CCRCs. By knowing the differences by residents' demographics and residential characteristics, the foodservice manager can establish strategies to increase the dining frequency of residents in the dining rooms of CCRCs.

  • The proposed encryption algorithm strengthens its security by converting pixel-specific values and changing pixel positions. The state transition matrix created by Wolfram's rule creates a complemented CA sequence with the maximum length. Then, we convert the sequence into a 2D basis image and go through a XOR operation with the original image. The final encrypted image is created by shear stressing and rearranging. The image stability analysis verified that the proposed encryption method has high security.

  • In order to get the basic information about the designing and manufacturing of special clothing which is suitable diplegia individuals, taking anthropometic measurements, the di-plegia's body dimension, standard dimension, their correlation, maximum, minimum, the relative deviation graph of Mollison and the body index were obtained. The writer examined their body development and abnormal somatotype and compared the difference with the normal somatotype. The results are as follows: 1 One characteristic of the body of diplegia individuals is that their lower parts are dis- proportionately developed, compared to their upper parts. 2. Diplegia individuals have smaller measurements than those of the normal; height, breadth, and circumference measurments of lower parts. And diplegia individuals have larger measur- ments; breadth and circumference measurements of upper parts, most of the length measur- ements. 3. In body index, diplegia individuals have lager measurments than those of the normals; most of index for stature and chest circumference and waist circumference index. And diplegia individuals have smaller measurments; most of the lower parts. 4. Change of somatotype according to age is unbalanced different from the normal's. 5. For the proportion of diplegia individuals, therefore a different pattern design of ciothing is required based on their special somatotype.

  • In this paper, a model is introduced named double relation chains (DRC) based on ordered sets. It is proved that using DRC and special relationships among the members of an alphabet, vectors of this alphabet can be stored and searched in a tree. This idea is general; however, one special application of DRC is the longest prefix matching (LPM) problem in an IP network. Applying the idea of DRC to the LPM problem makes the prefixes comparable like numbers using a pair of w-bit vectors to store at least one and at most w prefixes, where w is the IP address length. This leads to good compression performance. Based on this, two recently introduced structures called coded prefix trees and scalar prefix trees are shown to be specific applications of DRC. They are implementable on balanced trees which cause the node access complexity for prefix search and update procedures to be O(log n) where n is the number of prefixes. As another advantage, the number of node accesses for these procedures does not depend on w. Additionally, they need fewer number of node accesses compared to recent range-based solutions. These structures are applicable on both IPv4 and IPv6, and can be implemented in software or hardware.
