One of reliability measurements of vehicle is estimated by driving mileage but the reliability of component, such as an hydraulic clutch system, is defined from the number of successful operational cycle. Relationship between these reliability measurement variables(mileage and cycle) should be examined first of all in the reliability estimation of components. Relationship between mileage and cycles is commonly known as linear function. However, the gradient depends on the operational environmental condition. Therefore, estimation of mission profile variable should be done with correlation analysis at the same time. In this paper, we derive mission profile variable of an hydraulic clutch system by field vehicle test and suggest the determination process of durability test parameters of CMC(Clutch Master Cylinder) with mission profile variable.

From the analysis of proton NMR signals of human urine it is found that the signals corresponding to a phenolic compound of tyrosine are more frequently observed in cancer urine than in non-cancer urine. An effective reagent is obtained to detect the substance excreted in the urine and to find out a close connection with the result of the NMR analysis. An attempt is made to determine the reagent sensitivity and specificity for cancer diagnosis. The results of the attempt are respectively above 75% for both on an average.

For communication between heterogeneous conference systems, it is important to build a conference control protocol independent from signaling protocols. We simulate an XML-based conference control that is under consideration as a standard mechanism. We describe the framework and operations for easy implementation in heterogeneous conference systems. The simulation results show that the proposed control protocol provides a consistent service for an increasing number of conferences and participants in small to mid-size centralized conferencing.

Objectives: The objective of this study is to examine the effects of Emotion Freedom Techniques (EFT) group treatment program for Hwa-byung patients. Methods: Thirteen Hwa-byung patients have participated in the four weeks program of EFT group treatment and the program was executed once a week, for about one hour. After every session, the participants performed EFT by themselves in order to control their symptoms. Four weeks after the program ended, we interviewed the participants by using the semi-structured interview method to observe changes of Hwa-byung. All the data collected was summarized through the qualitative analysis method. Results: Results showed effects of the EFT group treatment program, with regards to the physical, cognitive and emotional aspects. Most of the participants experienced reliefs of Hwa-byung symptoms like chest tightness, hot flashes, insomnia and so on. Their ability to cope with stress improved and their re-experiences of past memories decreased. And their distorted self-images were also restored. Lastly, there was a decrease in negative emotions and an increase in positive emotions experienced by the participants. The participants could control their symptoms by performing self-enforcement. In addition, regarding the form of group therapy, the treatment was effective as it helped the participants to feel solidarity and social support. Conclusions: The EFT group treatment program can relieve the physical, cognitive and emotional symptoms of Hwa-byung. This program can be applied to the psychotherapy of Hwa-byung.

The purpose of this study is to estimate the characteristics and pollutant loadings of non-point pollutants that flowed in the streams on precipitation for pollutant loading reduction of Hwa-sung lake inflow streams. Although it has been made an effort to improve the water quality of Hwa-sung basin through the strategies for the preservation of water quality, it is shown that the water quality is not greatly improved. Because it has been industrialized and urbanized near Hwa-sung basin so that it is difficult to reduce the water pollution due to the increase in pollutant loadings of point and non-point sources. In this study, it is investigated the outflow characteristics of non-point pollutants that discharged with storm runoff and estimated the effect of runoff on Hwa-sung basin. The final goal of this study is to utilize the basic information for proper management and strategies of non-point sources on Hwa-sung basin. At the result of inflow streams, Ja-an stream that has the greatest pollutant loadings on precipitation is strongly influenced on the water quantity of Hwa-sung basin. On the other hand, it is shown that Nam-yang stream is strongly influenced on the SS concentration of Hwasung basin among them. Also, all streams; Nam-yang, Ja-ahn, Ah-eun stream; has the degree of slope more than or near 1 in the correlation results so that they have strong pollutant loading impact and the concentration of SS is the highest among other pollutants. So, specific studies on initial rain phenomena are more necessary to manage the pollutants economically. Also, the proper control of SS concentration is required to manage the effluent pollutants effectively on precipitation. So, it is necessary to consider the strategies for non-point pollutants as well as point pollutants when the new management is imposed to reduce the pollutant load for improvement of Hwa-sung basin.

This study on Jeung San Kyo, one of Korea's new religions, considered the name, kind, form, color and the thoughts of ritual dress which is involved in 15 religious blanches acting currently according to books and the actual research. The following is below. 1 Each names of ritual dresses called rigious branches are Bob Bok(법복), Doh Bok(도복), Yeah Bok(예복) and Jea Bok(제복). 2 In most religious blanches, ritual dress is the Korean cloths which Poh is wear above and Kwan is put on, and the form of Poh(포) is the similar with Durumagi(두루마기), Danryungpoh(단령포), Jungchimak(중치막), Jikryungpoh(직령포) etc, but not the form of Git, Moo and Yiohmim. Kwanmoh is named Chill-Chung-Kwan(칠층관), Yiun-Hwa-Kwan(연화관), Yiun-Kwan(연관), In-Hwa-Kwan(인화관), Tong-Chon-Kwan(통천관) etc. 3. In most religious orders but Dae Suun Jin Li Hueay(대순진리회), Jeung San Doe Jang(증산도장), Colors are used, white, lightblue, and yellow is used in Jeung San Pop Jong Kyo(증산법종교), Dong Doe Pop Jong Gyum Gang Doe(동도법 종금강도). White color means the mind of a people tradition, and light blue expresses an Oriental nation, namely, “Korea”, and is the color representing Jeung San Kyo, and yellow shows the central religion in the future. 4. Jeung San Kyo ceremony fashion reflects the ideologies of the principal role, the Um and Yang-five elements, and, nationalism according to form, color.

We have performed optical design of light guide plates (LGPs) for a photobioreactor by using an illumination design tool. An LGP having light emitting diodes (LEDs) as a light source on the four sides was designed by optimizing the distribution of LGP patterns and design of another LGP, on top of which sunlight was focused by a Fresnel lens, was executed. Finally, a hybrid-solar-and-LED-lighting scheme was described. Detailed design process and optical performances of the designed LGPs are presented.

In this paper, we propose a new real-time traffic monitoring scheme for the BcN, the RBC algorithm and investigate its operation. We implemented RBC algorithm and constructed the testbed and we confirmed the performance for this. The simulation result shows that traffic monitoring log size is reduced remarkably by using the RBC. An operation hour is reduced and a feedback support of Real-time is possible also. Consequently, RBC algorithm confirmed we are fit for Real-time TE plan for BcN.

Objectives : The aim of this study was to investigate the correlation between the effectiveness of Brief Qigong-based Stress Reduction Program(BQSRP) and personality. Methods : Twenty nine women and nine men from the community with symptoms of distress(mean age 39.4 years, SD=11.4) were randomized into a group receiving a 4-week intervention of BQSRP(n=19) or a waiting-list control group. All subjects completed the temperament and character inventory (TCI) before the intervention. Before and after the intervention period, questionnaires were completed on perceived stress scale(PSS), anxiety, and quality of life. Results : 1. Those who have higher temperament of harm avoidance or lower character of self-directedness showed higher PSS, Hwa-Byung character, Hwa-Byung symptom, STAI and lower WHOQOL-BREF scores. 2. In the BQSRP training group, a correlation analysis demonstrated an association between higher temperament of harm avoidance and greater improvement of perceived stress and an association between lower character of self-directedness and greater improvement of perceived stress. 3. Those who have high Hwa-Byung symptom scores prefer the breathing meditation and there were no differences in effects of BQSRP group by the preference Brief Qigong-based Meditation(BQM) component. Conclusions : These results suggest that a BQSRP training may be effective for those with higher harm avoidance trait and low self-directedness.

In 1895(32nd year of King Ko-Jong), Kyung-moo-chung as westernized police system was established and the uniform of the police developed. Regarding to the Uniform of the Kyung-bu-dai-sin(the Minister Kyung-bu) and to that of the Sun-gum(the low position of the Kyung-bu police), the Kyung-bu costume(Uniform of the police) is divided as Ye-bok(Formal uniform) and Sang-bok(Informal uniform). Ye-bok(Formal uniform) is put on in the case of the law described, and Sang-bok(Informal uniform) is an everyday wear. Ye-bok(Formal uniform) is composed of Ye-mo(hat), Eui(jacket), Go(trousers), Dai(decorative belt), Do(decorative sword), and Hwa(footwear). Sang-bok(Informal uniform) is composed of Sang-mo(hat), Eui(jacket), Go(trousers), and Hwa(footwear). Differences between Sang-bok(Informal uniform) and Ye-bok(Formal uniform) is the materials of the ornament, numbers of the decorative lines. Ye-bok(Formal uniform) has more grandeur[ornament. A historic changes in the Kyung-bu costume(Uniform of the police) during the late of Yi Dynasty was little but the decorative materials and the numbers of the decorative line.
