  • Duck is an important domestic animal, especially in Asia. Eighty five percent of ducks in the world are kept in Asia, especially in the East and South Asia regions. The ancestor of domesticated ducks was mallard (Anas platylhynchos), which are still migrating between north and southern parts in Eurasia. Ducks have been domesticated in China for at least 3000 years ago. Phylogenetic studies on ducks, employing electrophoresis of blood proteins, indicate a marked difference of genetic constitution between duck breeds in southeast Asia and those in northeast Asia. Duck embryonic ovary is much more active in secretion of sex steroid hormones especially estradiol than the embryonic testes. Estradiol secreted by the embryonic left ovary has an important role in female sexual differentiation in ducks. In the female ducks, plasma LH, estradiol and testosterone levels increase and reach peaks shortly before the first egg, while progesterone level reach a peak shortly after the first egg. In laying ducks oviposition mostly occurs in the last 3 hr of darkness and first hr of light ranging 02:00-06:00 under 14 hr light (05:00-19:00) and 10 hr darkness photoperiodic condition. Measurements of plasma hormone levels reveal that onset of darkness is a major signal for LH release from the pituitary and the subsequent release of progesterone from ovary, and for induction of ovulation in the female duck.

  • Shamanism is an ancient culture that is also considered as a religious rite by most of people. So, shamanism is an important part of Korean tradition and should be a significant base to the Korean exterior space organization theme. However in the field of Landscape architecture th principle of exterior spacing has not yet clearly been identified as shamanistic. Therefore believe that this study can exhibit a model for the study of shaministic space language and its application to one of Korean's village Namsa. The results of this study are summarized below; 1. Extracted models are Unspecialized· Circular·Coninuous space. These are analyzed on the basis of the shaministic space language. Also shaministic space languages are based with Korean common belief of eternal human identify, circular view of the world. 2. Applying the shamanistic space models to Namsa village shows that shamanistic space models follow the Korean space organization principle. Some area of the village do not apply, because they were built on the structure of the social hierarchy between families or the difference between head households and collateral households. 3. Applying the shamanistic space model to Namsa village shows that the shamanistic space model follows the Korean space organization principle. Therefore can say that Namsa village was built by a shamanistic system that pursued eternal human identity.

  • From the perspective of smart learning space, this study aims to take a look at the learning space of college students who do online remote learning in the COVID-19 era, and analyze their demands on what smart learning space they want. Furthermore, this study intends to provide valuable implications for the technology-enhanced learning environments by deriving design elements that make up the university's smart learning space. To achieve these goals, we conducted a review of prior studies, interviews with experts, and case analysis on smart learning spaces of major Korean and foreign universities, which are considered as innovative cases. Additionally, in order to confirm the difference between the importance level recognized by the college students and the current performance level for nine components of technology and for ten components of spaces and facilities, a paired t-test and an Importance-Performance Analysis (IPA) were carried out. According to the result of IPA analysis, Internet of Things from the technological aspects, a desk that can supply power and a flexible learning space from the aspects of spaces and facilities were found to have much lower performance than the importance. This result is meaningful in suggesting key design components for smart campus development in the post-COVID-19 world.

  • In this paper, we propose the effect of project-based robot education program on the interest toward robots and the computational thinking of elementary school students. Software education is being actively carried out around the world in order to cultivate software talents in accordance with the 4th industrial revolution. As a result, the importance of robots in education has increased, and education using robots has been actively introduced. However, the activities of simply assembling and repeating robots in schools were not effective in enhancing elementary school students' interest toward robots and computational thinking. Therefore, it is necessary to overcome traditional teaching-learning methods and to develop robot education. So, in this study, the robot education program that introduces project-based learning was developed for improvement of interest toward robots and computational thinking of elementary school students. In order to verify the developed education program, 114 elementary six grade students were selected as research subjects and the traditional teaching-learning method and project-based learning were applied to the experimental and control group. As a result, project-based learning was more effective for elementary school students' interest toward robot than traditional teaching-learning method. In computing thinking, the experimental group showed a significant improvement, but there was no statistically significant difference in the post-test.

  • The prevalence of diabetes continues to increase worldwide, and the problem is also important in Korea, and about 14% of Korean adults have diabetes. Alcohol consumptions are increasing rapidly around the world and are recognized as one of the major problems in the country. Alcohol consumption is an environmental factor previously known to be associated with the risk of developing diabetes. Alcohol consumption can cause problems in the endocrine system and gastrointestinal function, and oxidative stress of acetaldehyde, an ethanol metabolite, can damage beta cells in the pancreas. In the present study, we found the effect of alcohol intake on fasting blood sugar and the difference between men and women in the risk of diabetes according to alcohol intake. In men, the high-drinking group had a higher risk of diabetes than the non-drinking group (OR, 1.41; P=0.058). In women, the Moderate-drinking group had a lower risk of diabetes compared to the non-drinking group (OR, 0.42; P=0.039). The high-drinking group had a higher risk of diabetes than the non-drinking group (OR, 2.97; P=0.034). The group that consumed more than the WHO's daily alcohol intake risk standard tended to have a higher risk of diabetes than the group that did not (OR, 5.48; P=0.001). This study suggest that moderate alcohol consumption reduce the risk of developing diabetes, and high alcohol consumption increase the risk of developing diabetes.

  • In this paper, reliability-based design optimization (RBDO) of structures is addressed. For this purpose, the global search and optimization capabilities of genetic algorithm (GA) are combined with the efficiency and reasonable accuracy of an advanced moment-based finite element reliability method. For performing RBDO, three variants of GA including a real-coded, a binary-coded and an improved binary-coded GA are developed. In these methods, GA performs (finite element) reliability analyses to evaluate reliability constraints. For truss structures which include finite element modeling, reliability constraints are evaluated using finite element reliability analysis. Response sensitivity required for finite element reliability analysis is obtained by direct differentiation method (DDM) rather than finite difference method (FDM). The proposed methods are examined within four standard test examples and real-world design problems. The results illustrate the superiority and efficiency of the improved binary-coded GA. Results also illustrate that DDM significantly reduces the computational cost and improves the efficiency of the optimization procedure.

  • This study is to analyze that the pluralism is the main aspect of the modem fashion which examines the definition and the character of the pluralism. This will also consider the pluralism that appeared on the modern fashion which is based on them. The main point of pluralism is that the world is necessarily aware of plural and difference. Also many values which is focused on the previous generation, for instance disorganize of westernism, androcentrictrism, christianism and powerful nationalism, what is called unfamiliar, heterogeneous, the others and the circumference things. As these were rehabilitated, morality, ethics, religion or politics were all became possible to choose for one's taste. The pluralism expressed in modern fashion can be divided as collapse of genre, grafting the lower and higher orders cultivation, variety way of approaching in time, internationalism. The result for the consideration is that the pluralism has candid attitude for everything so that in the modern fashion is importing variety range of artistic definition. Namely, it is not only containing previous pure art, elegance art and element of artistic sublime beauty, but also has aesthetics of ugliness, deconstructive art and anti-fashion so that the definition of the art is getting vagueness and diverse.

  • According to the way of expression and the ritual procedure, there is a difference in the costume between Jinoggigut in Seoul and Sitggimgut, hereditary dance in the southern part of Joella province. Even though they share the same story, which is to soothe the spirit of the deceased and to listen to the grudge of the remained, the two shaman rituals are slightly different in their costumes. And the characteristics of the costume in Seoul Jinoggigut, and Jindo Sitggimgut are as follows; First, both in Seoul Jinoggigut, a spiritual dance and Jindo Sitggimgut, a hereditary dance, the universal roles of shaman costume, which are generally shown in "gut", are found-build a sacred environment, prepare for the experience of the spiritual world, listen to the grudge of the deceased and wish for God's bless. Second, the shaman costume has a special role to express specific and complex symbols-representing God on one hand, symbolizing the dead on the other. Third, unique symbols are found in the costume of Mangjachoendogut with the formality of the ritual procedure.

  • The core of this research studies the strategic alliance of airlines, container shipping liners, and port operators that have shown successful results through the recent differentiated strategic Alliance Network, although a difference of scale exists between these firms and the small and mid-sized International Logistics firms, but because of the worldwide traditional Alliance Network of International Logistics firms, HTFN's(High Tech Forwarder Network) half hearted attitude and the small scale alliance of the small and mid-sized International Logistics firms organized in 1998 cannot breakthrough the present strenuous situation. And these results, creating an attempt to save our country's International Logistics Industry which have fallen into depression, suggests an awakening of a new strategy based on specialized nationals innovative IT-which does not exist in the world market-by categorizing our country's small and mid-sized International Logistics firms which are active worldwide.
