Objectives: The purpose of this study is to use in therapy through considering representative oriental philosophical thought in terms of psychotherapy and Oriental medicine. Methods: This study examines psychotherapy and oriental aspects of "Diagram theory of InShimDoShim" that Yulgok, a Neo-Confucian scholar in the Joseon Dynasty, wrote about action of the mind and suggests ways to use it. Results and Conclusion: Diagram theory of InShimDoShim contains much content that can be applied in psychotherapy. It has a positive perspective of human nature and looked at life as realization of nature and life as subjective self-realization. Positive and negative experiences of life are expressions of positive nature. By reinterpreting these experiences, humans contribute to the goal of life that expresses their nature in a healthy way. Yulgok defines a healthy mind capable of living a good life as "an inshim who listens to doshim's command". Therapists can adopt this mindset as the goal of psychotherapy. Yulgok said that the way of manifesting nature is only possible through energy, and that the clear and tidy of this temperament creates a healthy and unhealthy mind. In this part, it is possible to apply therapeutic intervention of the diagram theory of InShimDoShim and Oriental medicine. Oriental medicine can calm temperament by using a treatment method to regulate energy, and clear energy creates a healthy mind and body. The principle that the mind is composed of nature and energy provides a basis for psychosomatic medicine.

Electromagnetic(EM) survey has been in use for over a half century as a standard routine for, mineral exploration in many parts of the world. But EM survey work and serious research effort were initiated in Korea only as late as in early 1980s, largely inspired by four pioneers who did their graduate studies in the U.S.A. in 1970s. Nevertheless domestic achievements in the field of EM survey are remarkable in the last two decades: the field operations and related interpretational skills appear to have reached a global standard, even compared with the most advanced in other countries, virtually in a whole spectrum of the method which includes magneto-tellurics(MT), Controlled Source Audio-frequency Magneto-tellurics(CSAMT), geomagnetic sounding, small loop survey systems, Very Low Frequency(VLF), Ground Penetrating Radar(GPR), time domain surveys, and noise analysis. Besides mineral exploration, EM survey has been applied in Korea to hydrogeology, geotechnical engineering, non-destructive investigation of structures, unexplored ordnance(UXO) investigation, environmental monitoring, and archaeological investigation as well. Now that original contributions of several Korean geophysicists are found even in new frontiers such as high-frequency EM survey, investigation in time-domain EM field for buried metal objects and structures, and also modem data inversion scheme, it is duly hoped that they make some technical breakthrough to unravel still entangled knots of EM survey method in a forseeable future.

This paper is designed to investigate the attributes of sound and emotion resided in traditional Eastern thought by looking into acoustic theories such as Sunguarakron (聲有哀樂論) in Akgi(樂記), Sungmuaerakron(聲無哀樂論) of Haegang and Akhakgebum(樂學軌範), Chongiron(天機論) in Choson(朝鮮) dynasty. Six types of emotions, namely sadness, pleasure, happiness, anger, respect, and, affection (哀心, 樂心, 喜心, 怒心, 敬心, 愛心) which is related with sounds was closely reviewed through Akgi(樂記). Also attributes of sounds such as loudness, sharpness, pitch, roughness, fluctuation strength and pleasantness was corresponded with plain & complicated(單複), pitch, good & bad(善惡) slow & fast(舒疾), loud & quiet(猛靜) respectively. In addition to this, this paper is narrowed down that the basic ideas about sound and emotions of Choson(朝鮮) confucian scholar was based on theory of music and rhythm on Akgi(樂記). Furthermore, the relationship between expressed sound and emotions which was revealed in Chongiron(天機論) has been examined. Finally, various applied research and studies will be promoted through this study, because this study will provide foundation which supports sounds and emotions of Eastern.

Sixty-eight clinical isolates of Stenotrophomonas maltophilia from inpatients of 2 university hospitals in Taegu were epidemiologically analyzed by using the minimum inhibitory concentrations of 25 antimicrobial drugs, biochemical reaction, pulsed-field gel elctropgoresis (PFGE), and PCR with enterobacterial repetitive intergenic consensus sequences as primer (ERIC-PCR). 1. All the strains were susceptible to minocycline. More than 57% were susceptible to sulfisomidine (Su), ciprofloxacin (Ci), Ofloploxacin (Of), nalidixic acid (Na), and chloramphenicol (Cm), and $19{\sim}35%$ to ceftazidime (Cd), trimethoprim (Tp), Ticacillin-clavulanic acid, and cefoperazone-sulbactam. Most isolates were resistant to ${\beta}$-lactam antibiotics such as ampicillin (Ap), carbenicillin (Cb), cefotaxim (Ct), cefoxitin (Cx), and aminoglycosides including gentamicin (Gm), tobramycin (Tb), amikacin (Ak). 2. All the isolates were multiply resistant of 5 to 17 drugs and showed 40 different resistance pattern types. 3. All the strains showed very similar biochemical reactions except ${\beta}$-galactosidase and nitrate reduction test. Fourteen strains selected randomly were classified 10 different pattern type by PFGE and ERIC-PCR. These two methods showed identical result. Four strains isolated from wound in 1994 showed similar MIC pattern and identical API 20NE profile, PFGE, and ERIC-PCR pattern indicating episodes of cross-infection among patients. These results indicate that PFGE or ERIC-PCR profile has comparable discriminatory power for epidemiological typing of S. maltophilia.

This study compared the fatty acid composition of wild and cultured specimens of the sea cucumber Apostichopus japonicus. We extracted total lipids from the specimens and determined their fatty acid compositions through capillary gas chromatography, resulting in the identification of 53 fatty acids. We found that wild sea cucumbers were rich in palmitoleic (C16:1n-7) and eicosapentaenoic acid (C20:5n-3), whereas cultured specimens were rich in eicosenoic (C20:1n-9) and arachidonic acid (C20:4n-6). In both types of sea cucumbers, the highest percentage of polyunsaturated fatty acids (PUFA) consisted of polar lipids (PL), followed by total lipids (TL) and neutral lipids (NL). Cultured sea cucumbers contained a higher percentage of total lipids (TL) than wild sea cucumbers did, whereas there was no significant difference between the two groups in the percentages of neutral (NL) and polar lipids (PL).

The living standards of Chinese people are gradually rising, which has led more Chinese students to come to Korea for their academic career. In this respect, it seems significant to find out how clothing involvement affects brand attachment and brand loyalty of Chinese college students in Busan. In this study, we attempt to identify factors of clothing involvement that influence Chinese students' turn of mind towards brand attachment and brand loyalty. The results of our analysis are as follows: 1. Five factors of clothing involvement have been derived: fashion trend, favorable impression, planning, indifference and choice. For brand attachment, three factors of brand show-off, brand gravity and brand pride have been derived. 2. Factors of clothing involvement have positive effects on factors of brand attachment, and brand attachment also have significant effects on brand loyalty. 3. Clothing involvement significantly affects brand loyalty indirectly via brand attachment.

This study was conducted in order to identify factors influencing depression in Chinese students in Korea, focusing on factors related to acculturation stress, academic stress and career stress. The participants of this study were 166 Chinese students studying in Korea. Data were collected from Sep. 7th to Oct 15th. The subjects' mean score of depression was 17.36(6.77), and their scores of acculturation stress, academic stress, and career stress were 69.51(19.06), 34.64(5.03), and 29.13(9.14), respectively. Acculturative stress and career stress were found to be factors influencing the depression level of Chinese students in Korea and the two factors' explanatory power was 51.9%. Based on the findings of this study, in order to lower Chinese students' depression level and help them lead a healthy academic life in Korea, it is necessary to assess their acculturative stress and career stress and to provide special intervention for students with high perceived stress.

In this study, we investigated the rotational characteristics which were comprised of directionality and linearity of target registration error (TRE) as a study in advance to enhance the accuracy of contour-based registration in neuronavigation. For the experiment, two rigid head phantoms that have different faces with specially designed target frame fixed inside of the phantoms were used. Three-dimensional coordinates of facial surface point cloud and target point of the phantoms were acquired using computed tomography (CT) and 3D scanner. Iterative closest point (ICP) method was used for registration of two different point cloud and the directionality and linearity of TRE in overall head were calculated by using 3D position of targets after registration. As a result, it was represented that TRE had consistent direction in overall head region and was increased in linear fashion as distance from facial surface, but did not show high linearity. These results indicated that it is possible for decrease TRE by controlling orientation of facial surface point cloud acquired from scanner, and the prediction of TRE from surface registration error can decrease the registration accuracy in lesion. In the further studies, we have to develop the contour-based registration method for improvement of accuracy by considering rotational characteristics of TRE.
