Today modern people have been searching on managing themselves in easy ways without side-effects to lead a healthy and quality life, accordingly concerns about complementary and alternative medicine have been increasing. The scientific term' complementary and alternative medicine' has been originally used in the US and has become the general term for natural treatment of medical methods, which can be suggested as an alternative solution to modern medical problems. There should be a study based on users' subjectivity to reinvigorate complementary and alternative medicine more than it does now. The purpose of this study is to offer basic materials when assessing practical applications on complementary and alternative medicine using the Q method which is subjective pattern analysis, help understand features of complementary and alternative therapy according to patterns, and find out preferences for patterns of complementary and alternative therapy. As a result patterns of complementary and alternative medicine were classified into three types. Firstly, type I prefers to biological/herbal treatment. Secondly, type II prefers to mixed treatments. Thirdly, type III prefers to manual healing.

Purpose: This study was done to investigate the application of complementary and alternative therapies (CAT) in patients with chronic liver disease. and to analyze the Influence of health locus of control (HLOC) on CAT. Method: Questionnaires on CAT and a multidimensional health locus of control (MHLOC) scale developed by Wallston and Wallston were completed by 141 patients. Result: Analysis showed that 44.7% of the patients had experience with CAT and 49.2% of the patients reported being willing to use CAT. Reliability scores for the scale were HLOC-I 0.7376, HLOC-P 0.6383, HLOC-C 0.7351. The mean scores for the HLOC were HLOC-I 24.86, HLOC-P 22.86, HLOC-C 16.00. There were no significant differences in mean scores for HLOC between the patients who had used CAT and those who had not. Eight response Patterns for HLOC were identified. Among them, 'yea sayer' was the largest group (27.0%). A significant difference was found in the 'yea sayer' pattern between the group who had used CAT and the group who had not. Conclusion: CAT relates to various cognitive factors such as HLOC. Further study is needed to examine the influence of HLOC on CAT and its response patterns.

In this paper, we evaluate the performance of frame synchronization words of pilot bit patterns which are used for the channel estimation and frame synchronization confirmation in W-CDMA(Wide band Code Division Multiple Access) system. W-CDMA system also uses compressed mode to make measurements from another frequency without a full dual receiver terminal. It is confirmed by using computer simulation that the proposed frame synchronization words also maintain the frame synchronization property in the compressed mode by using the complementary mapping relationship of preferred pair ROC(Receiver Operating Characteristic) curves with probability of detection and false alarm are used to analized the performance of the proposed frame synchronization words by using the various detection metrics such as LLRT(Log Likelyhood Ratio Test), GLRT(Generalied Likelyhood Ratio Test), soft and hard correlation tests in AWGN and Rayleigh fading channels. It is expected that the research results fer the performance of pilot bit patterns of this paper can be useful reference for the design and implementation of frame synchronization in 3rd generation W-CDMA system.

In this paper, we present a low-profile ultra-wide band half-wavelength loop antenna for UAV (Unmanned Aerial Vehicle) applications. The proposed antenna has an ultra-wide band using self-complementary principle. Also, the ground was located between radiators for reducing height of the antenna using image theory. Dimensions of proposed antenna have $0.20{\lambda}_L{\times}0.14{\lambda}_L{\times}0.16{\lambda}_L$ (${\lambda}_L$ is the free-space wavelength at lowest frequency). Measured -10 dB bandwidth was ultra-wide band as more than 50 : 1(over 0.3 GHz ~15 GHz). The radiation patterns of the antenna was omnidirectional like monopole antennas. Moreover, we tried the antenna mounted on under a fuselage of a scaled UAV. As a result, the proposed antenna on the UAV maintained ultra-wide band and omnidirectional radiation patterns at all frequencies.

Based on a substrate integrated waveguide(SIW) and a complementary split ring resonator(CSRR), electrically small antennas are proposed in this paper. Antenna's electrical size is reduced by introducing both CSRR and the eighth-mode substrate integrated waveguide(EMSIW). The EMSIW occupies only 12.5 % of the conventional SIW at the same dominant resonant frequency. In addition, the resonant frequency of the antenna is varied by rotating the CSRR on the EMSIW while keeping the same radiation patterns. The resonant frequency is changed from 4.74 GHz to 5.07 GHz by varying orientation of the CSRR from 0 to 360 degree. Unidirectional radiation patterns are observed and the measured peak gains are from 4.50 to 5.92 dBi.

Purpose: The purpose of this study was to investigate the perception and utilization patterns of complementary and alternative medicines (CAM) in patients with fibromyalgia syndrome. Methods: A total of 92 fibromyalgia syndrome patients participated in this study. Data were collected using a structured questionnaire and were analyzed with SPSS/WIN 23.0 program. Results: As a result, 59.8% of subjects had an experience of CAM and 33.7% of subjects have used until now. There were significant differences of the use of CAM between the group of CAM users and non-CAM users by education ($x^2$=4.04, p=.044), period of illness ($x^2$=15.03, p=.001), and period of treatment ($x^2$=12.10, p=.002). Relatively large numbers of patients understanded as that CAM was effective (58.7%) and fibromyalgia syndrome was controllable (75.0%). Moreover, there were significant differences of the use of CAM by the perception of CAM effects ($x^2$=4.15, p=.042), fibromyalgia syndrome ($x^2$=6.55, p=.038), and best treatment for fibromyalgia ($x^2$=11.03, p=.001). Conclusion: These results could be utilized as a basic data for developing nursing intervention for fibromyalgia syndrome.

Purpose: The purpose of this study was to study Complementary and Alternative Medicine (CAM) used among degenerative arthritis patients in Korea. Method: This study used a descriptive survey method. Study subjects of the study were 278 degenerative arthritics selected from hospitals located in Kyungpook province and Daegu city. Data were collected between February 15, 2007 and March 31, 2007. Results: 62.6% of degenerative arthritics had used CAM. Manipulative Methods has shown to be one of the most effective methods on CAM. The utilization of CAM may be interpreted mainly due to the desperate need find therapeutics of their disease by all possible means (57.5%). Major factors that affect the decision of the patient include family, relatives, friends(42%), and the other patients who were in the similar circumstance (32.8%). Effectiveness of CAM has shown the following result "for complete cure of symptoms(77.0%), for health promotion (42.0%) and for psychological stabilization (29.9%)". 43.7% of the patients answered that they stopped of using CAM because of non-effectiveness. Conclusion: This study found that CAM among degenerative arthritic patients was a popular alternative method. Therefore, some nursing-oriented intervention method is needed together with a systematic guidelines of CAM usage is required.

The principle of vowel dispersion claims that vowels are dispersed in the available phonetic space. However, SPAP and UPSID show that deviations from the patterns predicted by this principle are relatively infrequent of, for the most part, confined to matters of small scale, falling into a few definable classes. In this paper, we will discuss the vowel systems of 4 languages, Korean, English, Japanese, and Chinese, and will argue that vowels tend toward a balanced and wide dispersion in the available phonetic space by the complementary vowels.

Purpose: This study was conducted to investigate community health practitioners' knowledge of, use patterns of, and attitudes toward CAM. Method: The subjects of this study were 817 community health practitioners (CHPs) from 9 Provinces in Korea selected through convenient sampling. They completed and submitted self-report questionnaires at the annual meeting of CHPs or sent completed questionnaires to us by mail. Result: Of the CHPs, 8.1% had a certificate of CAM-related education program, and 39.9% worried about the efficacy of CAM. They knew about massage (74.0%), finger pressure (68.1%), hand acupuncture (67.8%), diet (65.5%) and herb (64.7%). They had used herb (43.3%), massage (36.8%), hand acupuncture (32.7%) and vacuum (31.2%) with positive effects and recommended residents to use them. Attitude toward CAM tended to be positive in those with certificates of CAM, those with high academic qualification, those aged 40 or below, and those working in Chungcheong-do. Conclusion: This study showed that CHPs were interested in CAM while they worried about the therapeutic effects of it. Further studies to draw cross-sectional and national data on the use patterns of CAM from the various population and standardized instruments to investigate the types of CAM were suggested.

In this paper, a SWB (Super-WideBand) dipole antenna with self-complementary structure is proposed for signal intelligence. The proposed antenna consists of a self-complementary dipole antenna and a tapered balun for balanced feeding. The measured -10 dB reflection bandwidth of the proposed antenna is more than 28:1 (0.73-20 GHz) and 3 dB axial ratio bandwidth is 3.25:1 (1.91-6.22 GHz) with RHCP (Right Hand Circular Polarization) at +z direction. The measured radiation patterns are omni-directional in lower frequency band and bi-directional in higher frequency band. The measured peak gain within -10 dB reflection bandwidth varies from 2.83 dBi to 7.66 dBi.
