The ability to develop curriculums is a crucial factor in evaluating the expertise of a teacher who teaches culture & art education. Establishing a one-year plan for classes is an effort to create a well-designed curriculum for the year and also to foresee the big picture of classes in the corresponding year. A curriculum should not be composed of merely educational content or a series of knowledge and skills. It should be well-designed, based on principles of a coherent plan. This study examines organizational principles on which common curriculums are based on and looks at how a curriculum can be designed, especially for cartoon & animation classes, as part of Culture & Art education, and which factors should be considered in planning. In the process of forming such a curriculum, these steps should be followed: considering educational standards for cartoon animation classes; determining the learning experience, organizing the learning experience; and, lastly, evaluating the level of learning. In addition, effective teaching strategies that reflect the characteristics of a class on cartoon animation should be formulated. This study suggests actual examples of an effective annual curriculum for cartoon animation classes based on all the factors presented above.

The purpose of this presentation is to review the situation of the Cheju broiler industry peculiarized with the integrated production and marketing system to some degree, which is not prevailed in the whole broiler industry in Korea, so as to study the case of the Cheju industry from the viewpoint of an economic integration. The economic integration in the broiler industry is grouped into three patterns： non-integration, quasi-integration and complete integration, which generally exist under the different type of market competition. The quasi-integration tends to be formed at all phases where the complete integration is not fully implemented, but the non-integration has begun to change its nature into partially integrated structure. The Cheju broiler industry is characterized by the geographical location of isolated market so that factor supplies and broiler products are marketed in the different conditions from those of mainland Korea, somewhat in an oligopolistic pattern. It was since early 1980's that the industry successfully had three dressing plants merged into one by virtue of entire growers ownership, which opened an era of an integrated industry centered on the function of dressing birds. The case of Cheju broiler industry today is to be referred to as a typical quasi-integration which is coordinated the function between growing and dressing birds directly and extended the functional cooperation to distribution of products indirectly, while factor supplies are traded independently. As a result of a quasi-integration, the growers are able to receive a fixed price set by the dressing plant of growers that has the power to adjust the supply of and demand for broilers produced and consumed in the Island. There are some problems, however, in the integration of the Cheju broiler industry, stemming mainly from the process of the structure change, ： 1) the difficulty of controlling the production of broilers, 2) continuing pressure on the integration by non-integrated sectors, 3) the challenge on the stabilized broiler market from the mainland, 4) limited effectiveness of consumer education activities, and 5) lack of leadership for the industry development through integration. It is projected that the partially integrated Cheju broiler industry will be continually developed toward the direction of a complete integration in due course, as the currently independent supply sectors are to be backward integrated. The case of the Cheju broiler integration, therefore, could be used as a reference for making the whole broiler industry in Korea develop toward the integrated structure in the future.

The purpose of this study was to present the quantitative data which riders can utilize teaching field by comparison analysis of kinematics according to skill level of rider during 2 strides rising trot with the JeJu's-Horse. Participated subjects was consisted of total 10 riders(unskilled: n=5, skilled: n=5). The method of experiment & analysis was based on 3D cinematography. Variables were consisted of temporal, linear & angular kinematics by each event & phase. The skilled assigned more ratio of elapsed time in air than support phase, had the less range of motion in up-down direction and more consistent velocity in lateral & forward direction and performed periodic up-down movement with alignment in vertical direction according to elapsing of phases. The skilled more flexed at elbow and extended backwardly according to elapsing of phases, while more flexed forwardly at hip & knee and plantarflexion at ankle. The skilled postured backward extension but the unskilled do forward flexion. That is, It was considered that the unskilled continued more unstable posture than the skilled during 2 strides in rising trot.

The Mathematical Model, which can describe the maneuvering motion of a ship in low speed, is highly required these days because it is directly related to the safety of ship in confused harbour. Kose has presented a new model for the low speed maneuvering motion, but the usefulness of it is not confirmed widely. Lets of difficulties are revealed in the case of low speed maneuver, The first is the fact that a ship moves the stirred water region for the longer time than in the case of high speed. So, the hydrodynamic forces, exerted on the hull need to be treated strictly, not by the ordinary differential equation with constant coefficients. Another difficulty is arised from the fact the lateral motion is relatively large comparing to the longitudinal motion in low speed. And, by the result the effect of cross-flow drag or vortex sheding effects are dominant. Besides, the captive model tests of low speed motion has lots of problems. For example, the hydrodynamic forces do not converge to a certain values for the long time. And the absolute values of measured forces are very small, so we must expend lots of efforts to raise up the S/N ratio of the experiments. In this paper, a new mathematical model for the maneuvering motion in low speed, is built up, and the usefulness is discussed, comparing with other models, for example, Kose's model or M.M.G. model or Cross-Flow model, The CMT data for a PCC model of 3.00 M length, released from the RR-742 of Japan, are used for the validation of each models.

Purpose: This study was conducted to develop a rubber-crawler type vehicle as a traveling device for harvesting water-dropwort cultivated in water contained paddy rice field in winter season. Methods: A commercial rubber-crawler type vehicle was used to investigate application of rubber crawler to the paddy rice field as preliminary test. As the result of the preliminary test, a both prototype traveling device with rubber crawlers for a water-dropwort harvest was designed with inclination of $45^{\circ}$ at the front-end and rear-end of crawler under the basic water depth of 0.6 m in the paddy rice field. The device was fabricated and attached to the experimental harvesting test devices on the front of the prototype vehicle. The size of the prototype crawler vehicle with a harvesting part is $2,800{\times}1,460{\times}1,040 $ (mm) ($L{\times}W{\times}H$) with weight of 9.21 kN (maximum). Sizes of the crawler of prototype vehicle are ground contact length of 900 mm, width of 180 mm, height of 1,070 mm and distance between center to center of crawlers of 720 mm. The side-overturn angle of the prototype was $26.4^{\circ}$. Results: Driving performance of the prototype vehicle in water contained paddy field were good at both forward and reverse (backward) directions as weights were applied. The drawbar pull and the maximum sinking depth of the prototype vehicle were 3.5 kN and 0.13 m respectively at water depth of 0.5 m, when the weight and bearing capacity of the prototype rubber crawler in the paddy field were 8.51 kN and 26.3 $kN/m^2$, respectively. Conclusions: Results of the driving test performance of the prototype crawler in paddy rice field at the water depth of 0.5 m were satisfactory. The prototype had enough drawbar pull and driving ability in the deep water contained paddy field.

For the selective separation of proteins, the solubilization and desolubilization of proteins in sodium-di-2-ethylhexyl sulfosuccinate (AOT)-isooctane reverse micellar system were investigated. Protein solubilization increased with increasing the concentration of AOT to 200 mM and then decreased above that concentration. Protein was solubilized into reverse micelles in the pH range below the isoelectric Point of each protein, pH 4-10 for lysozyme and pH 5-6 for trypsin and ${\alpha}-chymotrypsin$, Lysozyme, trypsin and ${\alpha}-chymotrypsin$ were efficiently extracted in the precence of KCl and NaCl while larger molecular weight proteins such as pepsin and BSA had high solubilization with $CaCl_2$. At higher ionic strength all proteins exhibited murk less tendency to solubilize and the increase of ionic strength resulted in the decrease of micelle size. Lysozyme was successfully back transfered at pH 12.2 and 1.0M KCl; trypsin at pH 12.6 and 0.5M KCl; and ${\alpha}-chymotrypsin$ at pH 6.7 and 0.5M KCl. In a test group separation experiments, complete separation of lysozyme from BSA could be obtained.

The terrestrial UV flux rapidly increased in late spring, as measured by the chemical actinometry at two elevations (near sea level and 1,100m above sea level) on Jeju Island. More intense UV fluxes were observed at higher altitudes. Any harmful effects of solar UV-B on the growth of soybean were not detected in UV-B-exclusion experiment. To ascertain the effect of UV radiation on vegetative growth, intact (㏖ wt 124000) and large (${\sim}120000$) phytochromes were irradiated with UV-B radiation. In intact phytochrome, the Pfr form accounts for 60% of the total phytochrome under stationary state conditions, whereas it accounts for 50% in large phytochrome. Calculated quantum yields for the forward and the backward phototransformations of phytochrome by UV were ${\phi}r=0.016$ and ${\phi}fr=0.010$ in intact phytochrome, and ${\phi}r={\phi}fr=0.012$ in large phytochrome, respectively.

The intelligent disk can improve the overall performance of the I/O subsystem by processing the I/O operations in the disk side. At present time, however, realizing the intelligent disk seems to be impossible because of the limitation of the I/O subsystem and the lack of the backward compatibility with the traditional I/O interface scheme. In this paper, we proposed new model for the intelligent disk that dynamically optimizes the I/O subsystem using the information that is only related to the physical sector. In this way, the proposed model does not break the compatibility with the traditional I/O interface scheme. For these works, the boosting algorithm that upgrades a weak learner by repeating teaming is used. If the last learner classifies a recent I/O workload as the multimedia workload, the disk reads more sectors. Also, by embedding this functionality as a firmware or a embedded OS within the disk, the overall I/O subsystem can be operated more efficiently without the additional workload.

The gap in academic achievement owing to entrance age in elementary school has been used as important basic data to formulate policies on school entrance system and other educational policies. Other countries have made further studies to prove the effect on academic achievement of age gap between students in the same grade. This study identified the clear difference in a component ratio in the participants and the successful candidates based on the by entrance age during the entrance examination of the "K" science education center for the gifted. Also, this study analyzed the difference in success in an examination depending on the season of birth between the participants and the successful candidates during the entrance examination. It also compared the birth ratio by season of each group including common students. Some preceding studies with common or backward students show the result that students who entered the school in full age have higher level of academic achievements than students in younger age. But the results of this study proved that gifted students who entered the school in full age did not have a high level of academic achievements. Like these studies, this study show the result that school entrance age works as an important factor of selection of gifted students. Students who entered the school in full age entered much more the "K" science education center for gifted students than students in young age.

Asian dust is a seasonal meteorological phenomenon influencing most East Asia, irregularly occurring during spring. Unusual heavy Asian dust event in winter was observed in Seoul, Korea, with up to $1,044{\mu}g\;m^{-3}$ of hourly mean $PM_{10}$, in 22~23 February 2015. Causes of such infrequent event has been studied using both ground based and spaceborne observations, as well as numerical simulations including ECMWF ERA Interim reanalysis, NOAA HYSPLIT backward trajectory analysis, and ADAM2-Haze simulation. Analysis showed that southern Mongolia and northern China, one of the areas for dust origins, had been warm and dry condition, i.e. no snow depth, soil temperature of ${\sim}0^{\circ}C$, and cumulative rainfall of 1 mm in February, along with strong surface winds higher than critical wind speed of $6{\sim}7.5m\;s^{-1}$ during 20~21 February. While Jurihe, China, ($42^{\circ}23^{\prime}56^{{\prime}{\prime}}N$, $112^{\circ}53^{\prime}58^{{\prime}{\prime}}E$) experienced $9,308{\mu}g\;m^{-3}$ of hourly mean surface $PM_{10}$ during the period, the Asian dust had affected the Korean Peninsula within 24 hours traveling through strong north-westerly wind at ~2 km altitude. KMA issued Asian dust alert from 1100 KST on 22nd to 2200 KST on 23rd since above $400{\mu}g\;m^{-3}$ of hourly mean surface $PM_{10}$. It is also important to note that, previously to arrival of the Asian dust, the Korean Peninsula was affected by anthropogenic air pollutants ($NO_3^-$, $SO_4^{2-}$, and $NH_4^+$) originated from the megacities and large industrial areas in northeast China. In addition, this study suggests using various data sets from modeling and observations as well as improving predictability of the ADAM2-Haze model itself, in order to more accurately predict the occurrence and impacts of the Asian dust over the Korean peninsula.
