We present a device model for organic light emitting diodes(OLEDs) which includes charge injection, transport, recombination, and space charge effects in the organic materials. The model can describe both injection limited and space charge limited current flow and the transition between them. Calculated device current, light output, and quantum and power efficiency are presented for different cases of material and device parameters and demonstrate the improvements in device performance in bilayer devices. These results are interpreted using the calculated spatial variation of the electric field, charge density and recombination rate density in the device. We find that efficient OLEDs are possible for a proper choice of organic materials and contact parameters.

The purpose of this study is to analyze the difference between local residents and tourist groups in the relationship between the motivation for visiting and the satisfaction of Chung Nam Dae which is the leading tourist attraction in the Chungbuk region. We obtained 200 validated samples each of the local residents in Chungcheongbuk-do Province and the tourists from outside of Chungcheongbuk-do Province with experience of visiting Cheongnamdae through the survey using the questionnaire organized through literature research. The analysis result showed that the relationship between motivation and satisfaction varied depending on the overall sample, local residents, and tourist and that the natural relaxation and convenience had a positive impact on satisfaction in all groups. There was a difference in the influence between motivation and satisfaction between the two groups. Four motivational factors, including natural relaxation, convenience, historicity, and relationship had the significant influence on satisfaction for the local residents while two motivational factors, including natural relaxation and convenience, had the significant influence on satisfaction for the tourists. Based on the results of the study, we presented the theoretical and practical implications and suggested follow-up studies.

This study had comparatively analyzed the influence factors of the farm village business on the local farmhouses centered on the level of importance and the level of performance. For this, a questionnaire survey had been conducted with 350 local residents who had participated in the Rural Field Forum of 14 villages, including Gyeongsangnam-do, Gyeongsangbuk-do, Chungcheongnam-do, Chungcheongbuk-do, Jeollabuk-do, etc. Excluding the insincere survey questionnaires, the final 232 people had been analyzed. As a result of the analysis of this study, the factors that have the influences on the diverse, rural areas had been compressed into the three factors of the lodging and the program, the special, rural area products, and the transportation and the accessibility. In the level of importance-level of performance analysis, it had been analyzed that the special, rural area products must maintain the continuity, that the transportation accessibility must avoid the excessive endeavor, and that the lodging program had a low priority order. Therefore, it can be said that it is necessary to concentrate the capability of the rural village business in the direction of developing the local specialties in the future. Next, after dividing the level of performance and the level of importance into the two groups each, the multiple group path analysis had been carried out. As a result, in the result of the analysis of the path that has an influence on the economic factor, the path coefficient of the level of importance of the transportation accessibility -> profit increase was 0.195+0.064 and the path coefficient of the level of performance of the transportation accessibility -> profit increase was 0.251+0.074. Therefore, both of them had the statistically significant amounts of the influences. This suggests that the transportation accessibility is an important element of the profit increase of the region. As a result, in the future, the research on the urban and rural exchanges using the even more convenient and inexpensive transportation means is needed. Most of them need the voluntary effort of the residents for being able to creatively develop and sell the native, agricultural, specialty products that are petty. Also, the rural areas need the diversities of the lodging programs and the recreational programs, a convenient reservation system, and the development of a unique tourism experience program. In the future, the researches that had been advanced in the even more detailed domain that is related to these factors are highly expected. Also, the analyses that had been carried out with even more areas and subjects as the targets are needed.

We hypothesized that supplementing finishing diets with palm oil would promote adipogenic gene expression but depress stearoyl-CoA desaturase (SCD) gene expression in intramuscular (i.m.) adipose tissues of Hanwoo steers during fattening period (from 16 to 32 mon of age). Fourteen Hanwoo steers were allotted randomly to 2 groups of 7 steers based on initial BW and fed either a basal diet (control) or the basal diet supplemented with 5% palm oil (BDSP). At slaughter, i.m. adipose tissue was harvested for analysis of adipogenic gene expression and fatty acid composition. There were no differences in BW or average daily gain between treatment groups. Supplemental palm oil had no effect on carcass quality traits (carcass weight, backfat thickness, loin muscle area, or marbling scores) or meat color values. Palm oil increased (p<0.05) expression of AMP-activated protein kinase-${\alpha}$ and peroxisome proliferator-activated receptor-${\gamma}$, but decreased (p<0.05) CAAT/enhancer binding protein-${\beta}$ gene expression and tended to decrease stearoyl-CoA desaturase gene expression in i.m. adipose tissue. Palm oil increased total i.m. polyunsaturated fatty acids (p<0.05) compared to the control i.m. adipose tissue, but had no effect on saturated or monounsaturated fatty acids. Although there were significant effects of supplemental palm oil on i.m. adipose tissue gene expression, the absence of negative effects on carcass and meat characteristics indicates that palm oil could be a suitable dietary supplement for the production of Hanwoo beef cattle.

Since Germany was unified in 1990, Korea became the only country that has the division in the world. This division has various bad effects on Korea's status with not reliable security, forfeited national impression, loss of tourism income and so on. Kim Jung-Il national defense committee chairman is the current dictator of North Korea which is a socialist state. Even if he is getting old, his successor is not proclaimed. In this situation, his sudden aggravation of health can cause seriously bad effects on diplomatic relations especially with South Korea. Therefore, the health information about Kim Jung-Il national defense committee chairman will be very important information. In order to deal this problem, we propose the method of extracting the Kim Jung-Il national defense committee chairman's health from his pictures which are recently open to the public by employing the diagnosis Ocular Inspection used in Oriental medicine. n order to get an accurate result, revising the Kim Jung-Il national defense committee chairman's pictures, which are not taken in a controled equal situation, is necessary. Therefore we employed the color analysis process with color revising and color differential comparing process without color revising. With these processes, we can make diagnosis of his diabetes and complications.

This paper proposed the validity and necessity of establishing the Jungwon Historical and Cultural Area by reviewing the historical characteristics of the name Jungwon and its temporal and spatial range. We also explored ways to utilize the Jungwon historical and cultural Area under the Special Act on the Maintenance of Historical and Cultural Areas. Jungwon, which means the center of the country, has strategic value as a key area connecting the Korean Peninsula to the north and south through the Geripryeong and Jukryeong. It also includes Chungju, which connects the Namhan and Bukhan Rivers . From the Mahan period, the areas of Cheongju and Jincheon, the Miho Stream basin to the west, and Chungju to the east were closely connected to each other. Afterwards, Baekje, Koguryo, and Silla engaged in a fierce battle to occupy the Jungwon area. Jungwon culture was born through the negotiation and fusion of the cultures of the three kingdoms. In particular, Silla continued to value the Jungwon area, demonstrated by the installation of Seowongyeong in Cheongju and Bukwongyeong in Wonju, centering on the Jungwongyeong. Since we have a historical view with a focus on ancient kingdoms, we have overlooked the full value of the history and culture of Jungwon. We need to recognize the importance of Jungwon area and think about how to utilize it. Therefore, we suggested in this paper that there be more public information services on the cultural heritage of Jungwon, the historical heritage experience, and the education programs for local residents. The development and operation of Jungwon's history, culture, and tourism contents, as well as the various academic research papers should be used to reveal the identity of the Jungwon historical and cultural area.
