  • The purpose of this research was to develop the education program on traditional living culture for home economics(HE) based on the 2015 revised national curriculum. The existing school curriculum for traditional living culture tends to overly focus on the theories about traditional culture and suffer from absence of continuity in learning activities. It can be argued that HE is an ideal subject for dealing with traditional living culture as it aims to develop students' ability to recreate the traditional culture, meeting present needs and trends. This study, thus, attempted to present the practical ways of improving the quality of education on traditional living culture by developing HE education program for high school students. To fulfill the purpose, this research, as a teaching topic, selected the traditional patterns and the "Obangsaek"(Korean traditional five colors) which can commonly be dealt with in the subjects of traditional Korean food, Korean costume and Korean style house. In particular, the program was developed following the ADDE process. In the stage of analysis, this article analyzed the HE curriculum and making activities included in HE textbooks based on the 2015 revised national curriculum, as well as the needs of teachers and students regarding traditional living culture education. In the stage of design, this study developed the instructional model, selecting class topics, tools and materials. In the stage of development, the programs on traditional living culture including costume, food and house were developed. In the evaluation phase, this research conducted the validity test and received the feedbacks from 12 HE educators in order to complete the programs. This study finally suggested that future studies in this area examine the effect of the presented programs on enhancing the students' perception of traditional culture and the will of developing and succeeding the traditional living culture.

  • Cardiac transplantation has been the treatment of patients with end-stage heart disease since it was first performed in 1967. In Korea the first case was performed in 1992 and 42 patients underwent heart trans- plantation so far. The purpose of this article is to report short-term result of cardiac transplantation at our center. Between April 1994 and September 1995, 14 patients had undergone orthotopic heart transplantations. There was 12 male and 2 female patients. Mea recipient age was 34 years(range 11 to 54 years) and mean donor age was 28.4 years(16 to 50 years). Mean graft ischemic time was 120.7minutes(80 to 280 minutes). The follow-up period after transplantation was 11 months(3 to 17 months). Recipient diagnosis included dilated cardiomyopathy in 10, ischemic cardiomyopathy in 2, valvular cardiomyopathy in 1, congenital complex heart disease in 1 patient. The preoperative status of the recipients were state I (50%) and ll (50%) by UNOS classification and class 111 (5 patients) and class IV (9) by NYHA functional class. All patients were treated with triple-drug immunosuppression (cyclosporine, azathioprine, steroid) and induction with RATG. The rejection episodes were 5 times in 3 patients during the follow-up. Causes of infection were aspergillosis (2), and hepes zoster (1), CMV pneumonitis (1). Permanent pace- maker was inserted in 1 patient. Currently 9 patients are alive with seven patients in WYHA functional class I and two in class l . The ejection fraction increased from preoperative value of 19.9 $\pm$ 3.4% to postoperative value of 69.0 $\pm$ 5.6%. The causes of death were cellular rejection (1),chronic graft failure due to size-mismatching (1),respirat- oxy insufficiency due to asthma attack (1), subarachnoid hemorrhage (1), and RIO humoral rejection (1).

  • In early Josun(朝鮮) era, the scholars, genteels, and high officials in Josun dynasty paid attention to Sijo(時調) who hoped Josun society would share Confucian values. Sijo poems written by them are based upon Confucian ideology, giving an opportunity to its members to make sure their homogeneity and helping Josun dynasty sustain its regime. Gyongichega(景幾體歌) has, however, already failed to be an appropriate genre to do these functions. Nevertheless, in the late Josun dynasty when there were agitation in class hieracy, development of currency economics, maldistribution of wealth, and pursuit of enjoyment, obscene poems turned out. Consequently these songs contributed to encroaching and eventually destroying the Josun dynasty. The question that who are in charge of creating and enjoying Sasulsijo(辭說時調) cannot be answered by approaching it in the social class point of view. The range of the maker or the reader of Sasulsijo in the late Josun dynasty was much more extensive than that in the early times. Not only aristocracy or the middle society but even some of the lower class may have made and enjoyed those songs. In the meantime, it is singer-songwriters whom Park, Hyogwan blamed for their profiteering abuse of obscenity that is supposed to have been mainly reponsible for the creation of those songs. Siga is a double-edged art in its essence--the good and the bad. The lewd songs were, in the early Josun, strictly controlled but in the late Josun dynasty, were thriving due to social changes. In this context, songs based on Confucian ideology as well as the ones focused on sexual love became decayed along with the collapse of the Josun dynasty. Even though, in the light of the history of Siga, those two types of Siga are underestimated in its artistic value, they have very special social historical meaning in doing positive and negative functions for existence and destroy of the Josun dynasty.

  • This study was conducted to investigate the population structure and dynamics of the Picea jezoensis stands which are located in Mt. Gyebangsan and surveyed from March to October 2012. Results showed that the diameter class distribution of P. jezoensis presented a reverse J-shaped distribution pattern with 32 trees less than 10 cm DBH, 20 trees in 10~30 cm DBH, and 11 trees more than 30 cm DBH. It showed seedlings and saplings of P. jezoensis seem to prefer areas with more sun light or with open upper layer. It was also observed that P. jezoensis preferes areas with organic soils and abundant water such as areas around stumps. Also, occurrences of P. jezoensis stands were analyzed through annual mean radial growth of the trees. And the results showed that the growth naturally or artificially occurred approximately on the years 1854, 1915, 1918, 1993 and 2002 years. Most of the gap-makers were classified as standing dead type with 23 individuals (45.1%).

  • This study aims to investigate science teaching and learning for the gifted in comparison with regular classrooms in elementary schools. A questionnaire was developed to survey gifted and general students' perceptions to elementary science teaching and teaming with employing a teaching and learning model for the gifted by Maker and Neilson (1995, 1996). The 28 item questionnaire consisted of four categories of content, teaching and teaming process, student product, and learning environment, and each category included six to nine items. Randomly selected 114 students from gifted classes and 99 students for regular classes responded to the questionnaire through the use of five-point Likert scale. It was found that there are significant differences between gifted and regular classes of science at all four categories of the teaching and learning model for the gifted. Therefore, science teaching and teaming for the gifted seemed to be differentiated from regular classes and emphasized students' creativity. However, no differences were appeared in a few items: study of gifted people and research methods (gifted=3.0; regular=.21 F=2.54), students' freedom of choice for topics of lessons, tasks, etc., (gifted=3.1; regular=3.0, F=0.31), student product addressed to real audience (gifted=2.8, regular=2.6, F=0.96), and students' high mobility to seek for data in library, etc. during class periods (gifted=2.3, regular= 2.3, F=0.01). It was concluded that science education for the gifted in Korea calls for quality improvement in terms of teaching and teaming in various aspects.

  • Taurine, 2-aminoethanesulfonic acid is widely distributed in animal tissues and has a variety of bio-logical activities. A recent worldwide study demonstrated beneficial effects of taurine on aging and age-associated disorders. In general, taurine levels in the brain decease when an animal is subjected to pathologic conditions such as ischemia-anoxia and seizure. But the taurine levles tend to increase in the brain in hypertensive state. In the present study, the blood-brain barrier (BBB) transport of [$^3$H]taurine was compared between spontaneously hypertensive rats (SHR) and normotensive Sprague-Dawley rats (SD) using intravenous injection technique in vivo. We also obtained pharmacokinetic parameters of plasma volume maker, [$^{14}$ C] sucrose and [$^3$H]taurine after inject to rats simulatenously. BBB permeability surface area product (PS) value of [$^3$H]taurine in SHR (16$\pm$2.9$\times$10$^{-3}$ ml/min/g) was significantly higher than that in SD (7.4$\pm$0.8$\times$10$^{-3}$ ml/min/g). There is also significant difference for brain uptake of [$^3$H]taurine between SHR (0.195$\pm$0.031%ID/g) and SD (0.058$\pm$0.003% ID/g). This is due to difference of area under the plasma concentration-time curve (AUC) and that of total clearance (Class) between SHR and SD. No significant difference was indicated from other organ uptakes such as lung, heart, liver SHR and SD. But also kidney uptake was much higher in SHR. In conclusion, [$^3$H]taurine in plasma was slowly eliminated in SHR than in SD and uptake of [$^3$H]taurine in SHR is much higher than that of SD. This results suggest increased taurine level in the brain in hypertension state have an any effect on the brain uptake of taurine.

  • This paper describes on the real-time monitoring of net setting and hauling process for fishing operations of Danish seine vessels in the southern waters of Korea as an application of a PC based ECDIS system. Tracking of fishing process was performed for the large scale Danish seine vessel of G/T 90 and 350 PS class using the fishing gear which the length of net, ground rope, head rope and sweep line including warp in both sides were 86m, 104m, 118m and 3,200m, respectively. Tracking information for net setting and hauling process was continuously recorded for 23 fishing operations performed on November and December, 2003. All measurement data, such as trawl position, heading, towing course and past track which was individually time stamped during data acquisition, was processed in real time on the ECDIS and displayed simultaneously on the ENC chart. The results indicated that after the separation of a marker buoy from Danish seiner, the averaged running speed of vessel and the averaged setting period while shooting the seine on the course of diamond shape to surround the fish school in the 23 fishing operations were 8.3 knots and 13.1 minutes, respectively. And with the maker buoy taken on board, the averaged running speed of vessel and the averaged towing period while closing the seine on the straight route was 1.0 knots and 47.0 minutes, respectively. After the closing stage of hand rope, the hand rope was towed by the averaged speed of 2.2 knots during the 13.0 minutes. The average area for route of diamond shape swept by sweep lines of the seine in 23 fishing grounds was $709,951.6m^2$. Further investigation is also planed to provide more quantitative tracking information and to achieve more effective surveillance and control of Danish seine vessels in EEZ fishing grounds.

  • Due to the global warming and unstable abnormal climate changes, water resources differences between regions and water shortage are occurring. Therefore, the water resources management is becoming more important for the stable securement of future water supply and demand. Researches on Smart Water Grid (SWG), which is considered as a new method, that can stably secure and maintain the water resources, are actively being conducted but it is still in infancy. Thus, this study aimed to design SWG simulator based on GIS in order to provide integrated water information in web environment. The user's requirements were analyzed for system development and important functions such as SWG current situation checking, future prediction, filtration plant situation checking functions were designed and data expression techniques using GIS and HTML5 were applied to enhance the understanding of the users. Also, when the emergency situations occurred, the solving process of the situations are reproduced to check the solution process using scenario reproduction functions. Use-case, class, sequence diagram, which are a design for real system development and defines the system usage contents of users, were written, and the story board was written to check the final development contents. This study designed a SWG simulator in order to support the water maintenance reacting to climate changes. The development of system is expected to help securing information to deal with emergency situations such as water shortage and help the decision maker to make decision through reproduction of scenario. The major functions were designed for the convenience of water resource manager and producer but new contents for consumers must be developed to enable duplex information transmission.

  • The purpose of this study was to evaluate the adaptability to tooth structure of composite resin and glass ionomer cement according to filling methods. In this study. two class V cavities were prepared on the buccal and lingual surface of each tooth of forty extracted human premolars. and they were randomly assigned into 4 groups with 10 teeth. The cavities of each group were filled with the CLEARFIL FII self curing resin(Control Group), Z-100 light curing resin (Group 1). $Vitremer^{TM}$ light curing glass ionomer cement(Group 2) and Z-100 light curing resin over the $Vitremer^{TM}$ liner(Group 3). The specimens underwent temperature changed from $5^{\circ}C$ to $55^{\circ}C$ five hundred times. After thermocycling. specimens were immersed in 2% methylene blue solution and stored in 100% relative humidity at $37^{\circ}C$ for 24 hours. And then. the specimens sectioned buccolingually. Degree of dye penetration at tooth-restoration interfaces were examined by Tool maker's microscope(x 200) and Image analyzer. The results were as follows : 1. On the occlusal margin. among the experimental groups. the group 2 showed the highest dye penetration($2.40{\pm}0.68$) and the group 3 showed the lowest dye penetration($1.15{\pm}0.37$). There was significant difference among the experimental groups(p<0.001). 2. On the gingival margin, among the experimental groups, the group 1 showed the highest dye penetration($3.30{\pm}0.57$) and the group 2 showed the lowest dye penetration($1.65{\pm}0.49$). There was significant difference among the experimental groups(p>0.001). 3. About total degree of dye penetration, the group 1 showed the highest dye penetration($2.25{\pm}1.17$) and the group 3 showed the lowest dye penetration ($1.43{\pm}0.55$). There was significant difference among the experimental groups(p<0.001). 4. The sum of dye penetration at occlusal margin was less than gingival margin. There was significant difference between occlusal margin and gingival margin (p<0.001). The results showed that differences were more pronounced at the gingival margin. Composite restorations inserted over the glass-ionomer liner demonstrated significantly less leakage than single restoration that used composite resin or glass-ionomer cement.
