The noise pressure scattered underwater on account of the engine revolution of a pole and liner, Kwan-Ak-San(G. T. 234.96), was measured at the locations of Lat. $34^{\circ}47'N$, Long. $128^{\circ}53'E$ on the 16th of August 1976 and Lat. $34^{\circ}27'N$, Long. $128^{\circ}23'E$ on the 28th of July, 1977. The noise pressure passed through each observation point (Nos. 1 to 5), which was established at every 10m distance at circumference of outside hull was recorded when the vessel was cruising and drifted. In case of drifting, the revolution of engine was fixed at 600 r. p. m. and the noise was recorded at every 10 m distance apart from observation point No. 3 in both horizontal and vertical directions with $90^{\circ}$ toward the stern-bow line. In case of cruising, the engine was kept in a full speed at 700 r.p.m. and the sounds passed through underwater in 1 m depth were also recorded while the vessel moved back and forth. The noise pressure was analyzed with sound level meter (Bruel & Kjar 2205, measuring range 37-140 dB) at the anechoic chamber in the Institute of Marine Science, National Fisheries University of Busan. The frequency and sound waves of the noise were analyzed in the Laboratory of Navigation Instrument. From the results, the noise pressure was closely related to the engine revolution shelving that the noise pressure marked 100 dB when .400 r. p. m. and increase of 100 r. p. m. resulted in 1 dB increase in noise pressure and the maximum appeared at 600 r. p. m. (Fig.5). When the engine revolution was fixed at 700 r. p. m., the noise pressures passed through each observation point (Nos. 1 to 5) placed at circumference of out side hull were 75,78,76,74 and 68 dB, the highest at No.2, in case of keeping under way while 75,76,77,70 and 67 dB, the highest at No.3 in case of drifting respectively (Fig.5). When the vessel plyed 1,400 m distance at 700 r.p.m., the noise pressure were 67 dB at the point 0 m, 64 dB at 600m and 56 dB at 1,400m on forward while 72 at 0 m, 66 at 600 m and 57 dB at 1,400 m on backward respectively indicating the Doppler effects 5 dB at 0 m and 3 dB at 200 m(Fig.6). The noise pressures passed through the points apart 1,10,20,30,40 and 50 m depth underwater from the observation point No.7 (horizontal distance 20 m from the point No.3) were 68,75,62,59,55 and 51 dB respectively as the vessel was being drifted maintaining the engine revolution at 600 r. p. m. (Fig. 8-B) whereas the noise pressures at the observation points Nos.6,7,8,9 and 10 of 10 m depth underwater were 64,75,55,58,58 and 52 dB respectively(Fig.8-A).

Robert Rauschenberg's artistic career has often been regarded as having reached its culmination when the artist won the first prize at the 1964 Venice Biennale. With this victory, Rauschenberg triumphantly entered the pantheon of all-American artists and firmly secured his position in the history of American art. On the other hand, despite the artist's ongoing new experiments in his art, the seemingly precocious ripeness in his career has led the critical discourses on Rauschenberg's art to the artist's early works, most of which were done in the mid-1950s and the 1960s. The crux of Rauschenberg criticism lies not only in focusing on the artist's 50's and 60's works, but also in its large dismissal of the significance of the imagery that the artist employed in his works. As art historians Roger Cranshaw and Adrian Lewis point out, the critical discourse of Rauschenberg either focuses on the formalist concerns on the picture plane, or relies on the "culturalist" interpretation of Rauschenberg's imagery which emphasizes the artist's "Americanness." Recently, a group of art historians centered around October has applied Charles Sanders Peirce's semiotics as art historical methodology and illuminated the indexical aspects of Rauschenberg's work. The semantic inquiry into Rauschenberg's imagery has also been launched by some art historians who seek the clues in the artist's personal context. The first half of this essay will examine the previous criticism on Rauschenberg's art and the other half will discuss the artist's 1955 work Rebus, which I think intersects various critical concerns of Rauschenberg's work, and yet defies the closure of discourses in one direction. The categories of signs in the semiotics of Charles Sanders Peirce and the discourse of Jean-Francois Lyotard will be used in discussing the meanings of Rebus, not to search for the semantic readings of the work, hut to make an analogy in terms of the paradoxical structures of both the work and the theory. The definitions of rebus is as follows: Rebus 1. a representation or words or syllables by pictures of object or by symbols whose names resemble the intended words or syllables in sound; also: a riddle made up wholly or in part of such pictures or symbols. 2. a badge that suggests the name of the person to whom it belongs. Webster's Third New International Dictionary of the English Language Unabridged. Since its creation in 1955, Robert Rauschenberg's Rebus has been one of the most intriguing works in the artist's oeuvre. This monumental 'combine' painting($6feet{\times}10feet$ 10.5 inches) consists of three panels covered with fabric, paper, newspaper, and printed reproductions. On top of these, oil paints, pencil and crayon drawings connect each section into a whole. The layout of the images is overall horizontal. Starting from a torn election poster, which is partially read as "THAT REPRE," on the far left side of the painting. Rebus leads us to proceed from the left to the right, the typical direction of reading in a Western context. Along with its seemingly proper title. Rebus, the painting has triggered many art historians to seek some semantic readings of it. These art historians painstakingly reconstruct the iconography based on the artist's interviews, (auto)biography, and artistic context of his works. The interpretation of Rebus varies from a 'image-by-image' collation with a word to a more general commentary on Rauschenberg's work overall, such as a work that "bridges between art and life." Despite the title's allusion to the legitimate purpose of the painting as a decoding of the imagery into sound, Rebus, I argue, actually hinders a reading of it. By reading through Peirce to Rauschenberg, I will delve into the subtle anxiety between words and images in their works. And on this basis, I suggest Rauschenberg's strategy in playing Rebus is to hide the meaning of the imagery rather than to disclose it.

Postoperative hypoxemia in the absence of hypoventilation occurs more often after thoracic or upper abdominal surgery than lower abdominal operations or surgery on extremities. Although the factors which produce postoperative alveolar collapse have not been fully evaluated, the dominant factor of postoperative hypoxemia is shunt of blood passing collapsed alveoli and the postoperative pain is associated with restriction of depth of breathing, sighing and movement. In 1979, the first successful clinical usage of epidurally administered morphine for control of postoperative pain was reported by Behar and associates. This study was carried out for twenty patients who received posterolateral thoracostomy with bleb resection between May 1990 and May 1991 and who were primary spontaneous recurrent pneumothoraxes under general endotracheal anesthesia. For the relief of post-thoracotomy pain following of the general anesthesia, we selected ten patients as control group which were treated intermittently IM with injection of pethidine(50 mg) according to the conventional method and another ten patients as study group which were managed with thoracic epidural analgesia. The tip of the catheter was inserted to T4-5 epidural space through T12-L1 or L1-2 interspinous region before the induction of the general anesthesia and then the epidural analgesics(0.25% bupivacaine 15 ml+morphine 3 mg) was injected once a day via the catheter until 4 th POD in the study group. The epidural catheters were removed at postoperative 4 th day in study group. Clinical observations were done about vital signs, ABG, tidal volume, FVC and occurence of adverse effects during postoperative 2hr, 8hr, 1st day, 2nd day, 7th day in both groups. The results were as follows; (1) The values of $V_T$ and FVC were significantly improved in study group(85% and 66%) as compared with control group(76% and 61%) during the postoperative 4 day of the epidural analgesia. (2) After the end of the epidural analgesia(7th POD), the values of FVC were improved invertly rather in control group(98%) than study group(84%). It suggested that the reduction of FVC in study group were caused by the raised pain sensitivity following the end of epidural analgesia. (3) The side effects of epidural analgesia such as transient urinary retention(2 cases), itching sensation(1) and headache(1) were noted.

This study was to suggest cultural landscape preservation, value creation, as well as utilization plan to help landscape development of Hahoe village by identify the existence of Okyeonsipyeong(玉淵十詠) natural features, which were set around Buyongdae(芙蓉臺) in Hahoe Village by Seoae(西崖) Ryu, Seongryong(柳成龍), and understanding their characteristics and meanings of natural features and meanings. Based on the writings of "Okyeonseodanggi" and "Okyeonsipyeong", the major results of this study are as belows. 'Okyeon(玉淵)' letters carved on the rocks, also known as the name of pavilion in Okyeonjeongsa(玉淵精舍), is the center of Okyeonsipyeong that symbolizes the enlightenment of clean noble man, as well as the symbolic locational expression of studying room. One of Okyeonsipyeong, 'Wansimjae', is assumed to be the name from the combination of two Buddhist names, 'Wanjeok(玩寂)' and 'Seshim(洗心)', 'Dangho(堂號)', lined on both sides with Wonlakjae, the residence of Seoae, as the center. Wansimjae is after all the natural feature indicating the overall Okyeonjeongsa as the core of Okyeonsipyeong with west edge Gyeomamjeongsa(謙巖精舍). Among ten Okyeonsipyeong natural features, Wansimjae(玩心齋), Ganjukmun(看竹門), Gyeomamsa(謙菴舍), Dalgwandae(達觀臺), Ssangsongae(雙松厓), and Dohwacheon (桃花遷) are on the right side of the stairway from Okyeonjeongsa to Gyeomamjeongsa, while Chuwoldam(秋月潭), Neungpadae(凌波臺), Gyeseonam(繫船巖), and Jijuam(砥柱巖) are on the road to the cliff under river cliff in Buyongdae as well as to the dock, and all are located within 500m radius close and diameter area. As the results of lexeme and context analyses of Okyeonsipyeong poet, they are mainly about Confucian teachings symbolizing the constancy of the classical scholar including ego becoming one with the nature and back to the nature, unworldliness and farsighted view, transcendence and seclusion, as well as integrity spirit. In Dohwacheon and Gyeomamsa poets, there is Tao characteristics and brotherhood that pursue fairylands such as Mooreungdowon(武陵桃源). To create tourism brand and landscape of Okyeonsipyeong, it is necessary to prepare storytelling plans including the letters carved on the rocks introduction in Buyongdae area, and also synopsis of the Silgyeongsusang musical, 'Buyongjiae(芙蓉之愛)' that is related to 10 natural features. In addition, the related plans of the experience road from Gyeseonam, which is the boat stop in Buyongdae, to Ganjukmun of Okyeonjeongsa, and again to viewing routes on the stairways to Gyeomamjeongsa using boats are necessary. For preliminary preservation and maintenance plans, the safety of the stairway from Okyeonjeongsa to Gyeomamjeongsa should be secured, the rock inscription should be preserved, landscape interpretation plates should be installed, trees and shrubs around Dohwacheon rock inscription should be removed, Dalgwandae letters carved on the rocks should be restored, and the bamboo forest outside Ganjukmun as well as Prunus persica plantation around Dohwacheon should be pointed out.

This study was to analyze the changes made in the landscape cognition in Yong-in City for the past 10 years. For the analysis, the landscape plan in 2001, and the survey data collected for the new 2012-landscape plan were used. The questions on the survey covered the cognition of the current landscape status, the evaluation of landscape depending on the types of landscape, the understanding of each element on the landscape, the residents' cognition, etc. In the evaluation of the status on current landscape, Everland was ranked outstandingly high as a symbol and a representative place both in 2001 and 2012. The image of the overall city landscape was changed from the image of unique, diverse, grand-scale and well ordered in 2001, to the image of wide, disordered, common and realistic. As the evaluation of individual landscape types such as the view of the mountain, the surroundings of the tourist attractions, colors, etc, has improved overall. The image of the city has been evaluated to improve gradually, especially in the level of individual element. In the study of participating the willingness of residents, despite the interest in landscape has been continued, the attitude for the actual participation in the action plan or the restriction of property right has been changed into a negative side. For the direction of the landscape plan, the residents are more interested in the detailed subjects : such as the financial support, the night landscape plan, the improvement of the problems, etc. During the last 10 years, the changes on the landscape cognition in Yong-in City have changed more in detail and specifically, the cognitions on the local government and developers changed positively. However the reducion of the participants' willingness suggested a review on the policies and the projects of the landscape.

In this study, the effects of a mixture consisting of vitamin E, vitamin C, pycnogenol and evening primrose oil (mixture LGNC-5) on ultraviolet light (UV) induced pigmentation and wrinkle reductions of normal healthy volunteers were studied. In a double-blind placebo-controlled study, each of 54 subjects took daily either 4 capsules of the mixture LGNC-5 (Group ABC; 282.5 mg/capsule) or placebo (Group Ganada). We irradiated 2.5 MED UV on the upper arms and measured the whitening effect by colorimeter-based L value. The level of wrinkle reduction was determined by image analysis using skin replica around the crow' feet, and the level of serum vitamin E was determined at baseline and 12 weeks. After 12-week oral administration, the treated group showed a significant reduction in skin pigmentation and wrinkles compared with the placebo group (p = 0.011 and p = 0.000005, respectively). Also, the level of serum vitamin E was significantly increased in the treated group after 12-week oral adminstration of the mixture compared with that in the placebo group (p = 0.0001). In conclusion, 12-week oral administration of LGNC-5 as a dietary supplement could be effective to reduce both UV induced pigmentation and skin wrinkle without side effects.

Inositol and phytic acid extracted from rice bran were investigated for applying cosmetics. Skin lotions containing $0{\~}3.0\;wt\%$ inositol and $0{\~}1.50\;wt%$ phytic acid were applied respectively, to the arm skins of 45 Asian women 20'~40's for 7 weeks. Improvement on moisture was evaluated. In addition, improvements on sebum, elasticity, and wrinkle were examined after applying placebo, inositol and phytic acid-containing skin lotions tot face, respectively. For $1.0\;wt\%$ inositol, it resulted in $19\%$ increase of moisture. The wrinkle reduction and elasticity improved $12.4%\;and\;17.0\%$ on average, respec-tively. Applying $0.5\;wt\%$ phytic acid resulted in $71.6\%$ increase the moisture. Improvements on wrinkle and elasticity were $16.9%\;and\;21.9\%$ respectivelv. hpplving inositol or phytic acid regardless of dry or oily skin, resulted in sebum value recovery to that of the normal skin after 2~4 weeks. Although inositol is inferior to phytic acid in improvements of the skin, phytic acid is not suitable to sensitive skin. So, $0~0.50\;wt\%$ of phytic acid were added to $1.0\;wt\%$ inositol and similar experiments were carried out. In case of added $1.0\;wt\%$ phytic acid, moisture increased $63.8\%$ approximately. Improvements on elasticity and reduction on wrinkle were $17.2%\;and\;17.4\%,$ respectively. Both skin types were turned to normal skin type after 2 weeks. It could improve the skin condition when used inositol added phytic acid. The optimized concentration of phytic acid was $0.10\;wt\%\;with\;1.0\;wt\%$ of inositol without side effect.

Rock units, relating with the Guamsan caldera, are composed of Guamsan Tuff and rhyolitic intrusions. The Guamsan Tuff consists almost entirely of ash-flow tuffs with some volcanic breccias and fallout tuffs. The volcanic breccia comprises block and ash-flow breccias of near-vent facies and caldera-collapse breccia near the ring fracture. The lower ash-flow tuffs are of an expanded pyroclastic flow phase from the pyroclastic flow-forming eruption with an ash-cloud fall phase of the fallout tuffs on the flow units, but the upper ones are of a non-expanded ash-flow phase from the boiling-over eruption. The rhyolitic intrusions are divided into intracaldera intrusions and ring dikes that are subdivided into inner, intermediate and outer dikes. We compile the volcanic processes along a single cycle of cadela development from the eruptive phases in the Guamsan area. The explosive eruptions began with block and ash-flow phases from collapse of glowing lava dome caused by Pelean eruption, progressed through expanded pyroclastic flow phases and ash-cloud fallout phases during high column collapse of pyroclastic flow-forming eruption from a single central vent. This was followed by non-expanded ash-flow phases due to boiling-over eruption from multiple ring fissure vents. The caldera collapse induced the translation into ring-fissure vents from a single central vent in the earlier eruption. After the boiling-over eruption, there followed an effusive phase in which rhyolitic magma was injected and erupted to be progressively emplaced as small plugs/dikes and ring dikes with many lava domes on the surface. Finally rhyodacitic magma was on emplaced as a series of dikes along the junction of both outer and intermediate dikes on the southwestern side of the caldela.

The delivery of optimal orthodontic treatment is greatly influenced by clinician's ability to predict and control tooth movement by applying well-known force system to dentition. It is very important to determine the location of the centers of resistance of a tooth or teeth in order to have better understanding the nature of displacement characteristics under various force levels. In this study, three dimensional finite element analysis was used to measure the initial displacement of the consolidated teeth under loading. The purpose of this study was to define the location of the centers of resistance at the upper six anterior segment. To observe the changes of six anterior segment, 200gm, 250gm, 300gm, and 350gm forces at right and left hand side each were imposed toward lingual direction. For this study, two cases, six anterior teeth and six anterior teeth after corticotomy, were reviewed. In addition, it was reviewed the effects of changes on the location of the center of resistance in both cases based on different degree of forces aforementioned. The results were that : 1. The instantaneous center of resistance for the six anterior teeth was vertically located between level 4 and level 5, which is, at 6.76mm, $44.32\%$ apical to the cementoenamel junction level. 2. The instantaneous center of resistance for the six anterior teeth after corticotomy was located vertically between level 4 and level 5, that is, at 7.09mm $46.38\%$ apical to the cementoenamel junction level. 3. Changes of force showed little effect on the location of the center of resistance in each case. 4. It was observed that the location of the instantaneous center of resistance for the six anterior teeth after corticotomy was changed more than the six anterior teeth without corticotomy to the apical part, and the displacement of the consolidated anterior teeth moved further in case of the consolidated teeth after corticotomy.

This study was attempted to provide the basic data for nursing intervention to improve the psychosociological adaptation of patients receiving chemotherapy for breast cancer by examining relationship between anxiety and hopelessness that they are experiencing and family support, in order to help them successfully cope with various psychological problems. This study was carried out with 93 breast cancer patients who are receiving chemotherapy in the injection treatment room of K University Hospital located in the downtown of Taegu after having underwent mastectomy in the hospital between December 1995 and August 1996. This study used the systematized questionnaires which contain 7 questions about general characteristics, Spielberger's trait anxiety & state anxiety scale, the tool that WON(1987) modified the hopelessness scale which was developed by Beck et al.(1967) and the family support tool made by TAE(1985). By using the SPSS/PC program, this study obtained the real number and percentage for the general characteristics of the subjects, and mean and standard variation for the degrees of trait anxiety, state anxiety, hopelessness and family support. The correlation between each variables was identified on the basis of the Pearson Correlation, and the degrees of trait anxiety, state anxiety, hopelessness and family support in the general characteristics of the subjects were analyzed by using the t-test, ANOVA, and Duncan test. The results of this study were summarized as follows. In the general characteristics of the subjects, most of each group were 51 years old or more and the middle class in income, had educational background under elementary school, no job, Buddhism in religion and spouse, and were receiving chemotherapy using MTX and 5FU. It was shown that the degree of the subjects' trait anxiety is, on an average, 50. 29, state anxiety 49. 68, hopelessness 51. 46 and family support 34. 28. Both trait anxiety and hopelessness showed normal correlation ; the higher the degree of trait anxiety is, the higher the degree of hopelessness is, while trait anxiety and family support showed reverse correlation ; the higher the degree of trait anxiety, the lower the degree of family support that the subjects perceive is. State anxiety and hopelessness also showed normal correlation ; the higher the degree of state anxiety is, the higher the degree of hopelessness is. Family support and hopelessness showed reverse correlation ; the higher the degree of family support is, the lower the degree of hopelessness that the subjects perceive is. And family support and state anxiety showed reverse correlation but there was a statistically significant difference. The degree of trait anxiety in the general characteristics of the subjects showed a significant difference by age, job and religion, the degree of state anxiety a signigicant difference by job and religion, the degree of hopelessness a signigicant difference by age, educational background and existence or not of spouse. In conclusion, the breast cancer patients receiving chemotherapy perceive anxiety and hopelessness due to several causes such as diagnosis itself or side effects of chemotherapy, so that it is required not only to develop specific nursing interventions including family support to alleviate anxiety and hopelessness but also to apply such interventions to clinical practice.
