This study was aimed to examine the quality characteristics of the bread with the muffin added with the by-product of fermented ethanol from wheat rye that has high $\beta$-glucan contents. In the muffin added with TEFB (Triticale Ethanol Fermentation By-product), the height of the muffin decreased as the additive contents increased. There was no significant difference among the volumes of the muffins added with TEFB 0%, 5%, 10% and 15%. In the muffin added with TEFB, the height of the muffin decreased as the additive contents increased. In the moisture measurement of TEFB muffin, the moisture contents increased as the TEFB additive contents increased. Using SEM, showed that as TEFB additive contents increased, gluten contents was relatively lowered, which led to the reduced gas retention power and generation of rough tissues. In chromaticity, as the TEFB additive contents increased, the brightness decreased and the redness and yellowness decreased as well. The result of texture measurement showed that as the TEFB additive contents increased, hardness increased. springiness decreased gradually as the TEFB additive contents increased. There was no significant difference in cohesiveness (p<0.005). Although there as signigicant difference between the control group and the additive group in gumminess (p<0.005), there was no significant difference for a certain amount of additive contents (p<0.05). While there was significant difference in chewiness between the control group and the additive group (p<0.05). there was no significant difference for a certain amount of additive contents (p<0.05). The result of taste test of TEFB added muffin showed that the preference for the muffins added with 5% or more TEFB decreased. This study found that more than 5% of TEFB additives to muffin decreases the preference level.

In this study, we investigated the anti oxidative potential and protective effects of water extract of Leonurus sibiricus L. leaf (LSLW) against ultraviolet B (UVB)-induced oxidative damage in human keratinocytes (HaCaT cells). To evaluate the anti oxidative activity of LSLW, we measured DPPH radical, hydroxyl radical, hydrogen peroxide, superoxide anion scavenging activities, lipid peroxidation inhibition, and reducing power of LSLW. For induction of oxidative stress in HaCaT cells, the cells were irradiated with UVB at 40 mJ/㎠. To investigate the protective effects of LSLW against UVB, we measured cell viability and apoptotic bodies using annexin V staining. LSLW showed anti oxidative activities by scavenging DPPH radical, hydroxyl radical, hydrogen peroxide, superoxide anion and by reducing lipid peroxidation. In addition, LSLW showed high reducing values. The UVB-induced oxidative conditions led to cell apoptosis. However, treatment with LSLW ameliorated oxidative stress conditions, including inhibition of cell death, apoptotic body. Taken together, LSLW exhibited anti oxidative and protective effects against UVB-induced damage in HaCaT cells. Thus, LSLW could be useful for the development of cosmetics for UVB-induced skin aging.
The purpose of this study is to analyze converged factors affecting learning flow in nursing college students. The study conducted survey on 200 nursing students attending a college in Chungcheongbuk-do. The study processed data using descriptive statistics, t-test, ANOVA and Pearson correlation coefficients and multiple regression analysis for the analysis. As for the relationship between self-leadership, social support and learning flow, the higher self-leadership(r=568, p<.001), and social support (r=.412, p<.001) led to higher learning flow of the study subject. The influential variables of learning flow was self-leadership with 33.0% of explanation power(${\beta}=.501$, p<.001). Likewise, the study confirmed that self-leadership is a very significant variable of learning flow of nursing students. Based on the theoretic grounds, there is a need to seek measures to improve learning flow by improving self-leadership of nursing students.
The offshore trawl fishery is seeking its survival way to overcome current management conditions in red, resulted from the bilateral agreement with China and Japan. However, this movement magnifies conflicts between fisheries on the contrary and it is thought to be impossible to get over current situations. For all that, this study is aimed at investigating how this current situations have occurred. The management freedom as response to the change in fishing conditions of a certain fishery, in case of Korea, is affected by institutional regulations. The example of this is controls on fishing gears, fishing vessels, and fishing grounds. The most exposure of this control is a segmentation of institutional fisheries. The initial segmentation of the offshore trawl fishery in Korea was occurred in the period of Japan's colonization when the degree of use of fishing grounds was limited geographically. At that time, fisheries were divided by fishing areas, but it did not divide the fishery itself. The large - sized fishing vessels were developed politically to be more competative to Japanese fishing vessels since 1950s. During this time, the trawl fishery was merged into current Eastern trawl fishery and South - Western trawl fishery. It was also inevitable to divide into the pair trawl and single trawl fishery as a result of the physical mergency between Western trawl and Southern trawl fishery. In order to develop the trawl fishery, new licenses were issued on the shrimp trawl fishery, through which it was expected to boost the trawl fishery. As opposed, the shrimp trawl fishery was changed into the mid - sized trawl fishery, targeting on the eastern fishing areas and the large - sized trawl fishery was developed since the late of 1970s with the development of filefish processing industry. The large trawl fishery that led in development of offshore trawl fishery since the late of 1950s was started to divide into a pair trawl and single trawl according to the fishing method and capital power. It finally became an institutionally independent fishery in 1980s, respectively. Looking into these historical process, the segmentation of the trawl fishery is thought as a result of the lack of long - term perspective and as a production of trial and error resulted by unprepared policy. As a result, these segmentation of fisheries roles as critical obstacles in harmonization of fisheries and in overcoming of current situations. Therefore, the review of this institutional segmentation of the offshore trawl fishery should be taken for an optimal redistribution of fishing grounds suits with business and fishing technology. For this, the fishery must be divided into large capitalized fishery and small - mid fishery with consideration of capital, fishing method, and the condition of use of fishing grounds. In addition to this, by limiting outline of fishing ground that the large fishery can harvest, it must allow for the small - mid fishery to catch with its own boundary. Furthermore, by launching buyback programs on the trawl, eastern trawl, pair trawl, it can provide broader fishing grounds where the fishery can harvest with management freedom.

This study evaluated the quality characteristics of dried noodles made of wheat flour supplemented with different concentrations of skate powder. Cooking quality, mechanical texture properties, gelatinization temperature and viscosity were measured, after which sensory evaluation was performed with prepared noodles. Water binding capacity, solubility and swelling power of the composite skate powder and wheat flours were higher than those of pure wheat flour. Gelatinization temperature of the composite skate powder and wheat flours increased, while initial, interim, and maximum-viscosity at $95^{\circ}C$, decreased, with increasing skate powder content. In relation to color values, increasing skate flour content led to decrease in L and b values and increase in a value. For the textural characteristics, the addition of skate powder increased hardness, springiness, chewiness and adhesiveness. Overall, noodles made with 3% skate powder were preferred compared to other samples.

Emergencies and disasters can happen any time without any warning, and things can change and escalate very quickly, and often it is swift and decisive actions that make all the difference. It is a responsibility of the building facility management to ensure that a proven evacuation plan in place to cover various worst scenario to handled automatically inside the facility. To mapping out optimal safe escape routes is a straightforward undertaking, but does not necessarily guarantee residents the highest level of protection. The emergency evacuation navigation approach is a state-of-the-art that designed to evacuate human livings during an emergencies based on real-time decisions using live sensory data with pre-defined optimum path finding algorithm. The poor decision on causalities and guidance may apparently end the evacuation process and cannot then be remedied. This paper propose a cloud connected emergency evacuation system model to react dynamically to changes in the environment in emergency for safest emergency evacuation using IoT based emergency exit sign system. In the previous researches shows that the performance of optimal routing algorithms for evacuation purposes are more sensitive to the initial distribution of evacuees, the occupancy levels, and the type and level of emergency situations. The heuristic-based evacuees routing algorithms have a problem with the choice of certain parameters which causes evacuation process in real-time. Therefore, this paper proposes an evacuee routing algorithm that optimizes evacuation by making using high computational power of cloud servers. The proposed algorithm is evaluated via a cloud-based simulator with different "simulated casualties" are then re-routed using a Dijkstra's algorithm to obtain new safe emergency evacuation paths against guiding evacuees with a predetermined routing algorithm for them to emergency exits. The performance of proposed approach can be iterated as long as corrective action is still possible and give safe evacuation paths and dynamically configure the emergency exit signs to react for real-time instantaneous safe evacuation guidance.
This study focuses on the problem of feminization of poverty that is formed within family relations. In order to approach this question, this study analyses the process of becoming poor through the life stories of ten woman are now heads of a household. There are differences among the study participants in the process of becoming a member of a low-income class. I have classified them into two groups depending on the routes they are led into the low-income class; one is the continuation of poverty group, and the other is the new members of the low-income class group. The continuation of poverty group is the case where they have been poor since their childhood and are still poor in their adulthood. The new members of the low-income class group is the case where you have become a low-income class sometime around divorce. The difference of the groups are related to the differences of the ways the power relationships work within a family. Women head of a household are prone to poverty because of the discrimination in formation, distribution and control of resources in their original family and their family formed by marriage. The norm of male breadwinner worked as a discrimination device. But this kind of discrimination device showed differences in their workings according to class. The continuation of poverty group experienced exclusion in the gendered responsibility of supporting the family and maintaining the family, whereas the other group experienced exclusion through the gendered nature of the distribution and control of resources. By showing that the presupposition of discussions on the poverty of woman head of a household is false, these findings challenge the existing view that as long as 'The Family' is maintained women will not be poor.
Due to the recent development of globalization and supply chain management, growth of international trade has led to increasing cargo volume around the world. Since maritime logistics environments have changed, increased container ship size, improvement of harbor equipment, global port operation and rapid technological development have had an significant effects on shipping and port industry, which is contributing to competitiveness of port. Since a larger volume of port throughputs are generally regarded as an indicator of the more competitive port, inefficient port operation could reduce its competitiveness. On the other hand, high efficient ports could increase their competitive power while increasing cargo volume. This study aims at comparing competitiveness of the ports in the Northeast Asia by investigating changes of container throughputs and evaluating efficiency performance of ports. Shift-Share analysis and Data Envelopment Analysis(DEA) have been conducted with 21 Northeast Asian ports and then separated them into 4 groups for comparative analysis to identify competitive position of each port. The results of this study show that Incheon and Gwangyang port have been decreased container cargo volume, while volume of Busan port would increase by means of active marketing, various route development and incentive policy for the port.
Electrogastrography(EGG), the cutaneous recording of the myoelectrical activity of the stomach using surface electrodes, is attactive due to its non-invasiveness. Despite many attempts made over the decades, analysis of surface EGG has not led to identification of contraction-related electrical response activity of the stomach that would help the clinician to diagnose motility disorders of the stomach. We propose feasible methods to detect the gastric contraction by spectrum analysis and vector analysis of the surface EGG signal. A running spectral analysis(RSA) based on the fast Fourier transform (FFT) was applied to the filtered EGG signal. The powers of dominant frequency and its harmonics were compared with gastric contraction signals such as the strain gauge signal from the gastric serosa in dog or the antropyloric pressure in human. And we also carried out vector analysis of the filtered EGG signals obtained from three paired electrodes. The amplitude and direction of the calculated EGG vector were analyzed and compared with the gastric contraction signals. From the spectrum analysis, we found that the increase of the power of the first harmonic of the dominant frequency was highly correlated with the gastric contraction. And from the vector analysis of the EGG signal, we found a typical change of the amplitude and direction of the EGG vector, which can indicate occurrences of the gastric contraction.
The purpose of this article is to examine the 'Discussion of maritime defense' which began to be discussed from the late Goryeo dynasty to the early Joseon dynasty and the process of establishing a maritime defense system. Also it can identify changes in the aspects of the naval ship operation and their strategic tactics during the reign of King Sejong. Japanese raiders began a full-scale invasion from 1350 at the late Goryeo Dynasty, So the government realized the need to raise the 'Sea power' and to organize the maritime defense system for defending enemy invasion. for example, the reinforcement of naval forces, construction of warships, develoment of weapon systems and so on. which have achieved remarkable growth while continuing, have also been used to carry out a three-time 'Conquest of Daemado' in 1389, 1396, 1419. Until then, however, it is difficult to interpret that the naval forces had a systematic and organizational combat operation system. According to fighting patterns on combat reports before the early days of King Sejong's reign, Our naval forces had no advantage over the Japanese raiders in terms of their capabilities and tactics. Then, the period of King Sejong marked a watershed in maritime defense history. Based on accumulated experience of naval battles and force Projections, The paradigm shift of the naval strategic tactics for maritime defense has occurred. First, the capability of the naval vessels has improved. for example, ship speed, durability, and weather resistance. Through these efforts, navy forces were able to pursue and attack, destroy enemy's ships by taking advantage of the 'Ship speed superiority'. This has led to tactical shifts from defensive to offensive. Second, purpose to support offensive tactics, the government put a strategic plan into practice that is the forward depolyment of naval bases from the inland to the coast, considering the 'sea environment' and 'threat'. By doing so, Joseon dynasty was able to secure 'the command of the sea'. This may be a little different from the perception of the so-called 'peace period' that King Sejong's era. We need to remember that Joseon dynasty was working hard for its defense. When studying history of maritime defense, these strategic and tactical elements must be fully considered. Only then we can have a coherent understanding of the many naval battles in the past, including the Imjin War(1592-1598).
