The aims of this study were to understand and to predict the determinent factors affecting the exercise behaviors and physical fitness by testing the Pender's revised health promotion model, and to help the patients with rheumatoid arthritis and osteoarthritis perform the continous exercise program, and to help them maximize the physical effect such as muscle strength, endurance, and functional status and mental effects including self efficacy and quality of life, and improve the physical and mental well being, and to provide a basis for the nursing intervention strategies. Of the selected variables in this study, the endogenous variables included the physical fitness, exercise score, exercise participation, perceived benefits of action, perceived barriers of action to exercise, activity-related affect(depression) and perceived self-efficacy, interpersonal influences(family support), situational factors(duration of arthritis, fatigue) and the exogenous variables included personal sociocultural factor(education level), personal biologic factor(body mass index), personal psychologic factor(perceived health status) and prior related behavior factors(previous participation in exercise, life-style). We analyzed the clinical records of 208 patients with rheumatoid arthritis and degenerative arthritis who visited the outpatient clinics at H university hospital in Seoul. Data were composed of self reported qustionnaire and good of fitness score which were obtained by padalling the ergometer of bicycle for 9 minutes. SPSS Win 8.0 and Window LISREL 8.12a were used for statistical analysis. Of 75 hypothetical paths that influence on physical fitness, exercise participation, exercise score, perceived benefits of action, perceived barriers of action to exercise, activity-related affect(depression) and perceived self-efficacy, interpersonal influences(family support), situational factors(duration of arthritis, fatigue), 40 were supported. The physical fitness was directly influenced by life-style, perceived health status, education level, family support, fatigue, which explained 12% of physical fitness. The exercise participation were directly influenced by life-style, education level, past exercise behavior, perceived benefits of action, perceived barriers of action, depression and duration of arthritis, which explained 47% of exercise participation. Exercise score were directly affected by perceived self efficacy. BMI, life-style, past exercise behavior, perceived benefits of action, family support, perceived health status. perceived barriers of action, and fatigue, which explained 70%. Perceived benefits of action was directly influenced by BMI, life-style, which explained 39%. Perceived barriers of action were directly influeced by past exercise behavior, perceived health status, which explained 7%. Perceived self efficacy were directly influeced by level of education, perceived health status, life-style, which explained 57%. Depression were directly influeced by past exercise behavior, BMI, life-style, which explained 27%. Family support were directly influeced by life-style, perceived health status, which explained 29%. Fatigue were directly influeced by BMI, life-style, perceived health status. which explained 41%. Duration of arthritis were directly influeced by life-style, past exercise behavior, BMI, which explained 6%. In conclusion, important variables for physical fitness were life-style, and variable affecting exercise participation were life-style. Perceived self-efficacy of exercise was a significant predictor of exercise score. BMI, Life-style, perceived benefits of action, family support, past exercise behavior showed direct effects on perceived self-efficacy. Therefore, disease related factor should be minimized for physical performance and well being in nursing intervention for patients with rheumatoid arthritis, and plans to promote and continue exercise should be seeked to reduce disability. In addition, Exercise program should be planned and performed by the exact evaluation of exercise according to the ability of the patients and the contents to improve the importance of exercise and self efficacy in self control program, dedicated educational program should be involved. This study suggest that the methods to reduce the disease related factors, the importance of daily life-style, recognition of benefit of exercise, and educational program to promote self efficacy should be considered in the exercise behavior promotion and nursing intervention for continous performance. The significance of this study is also thought to provide patients with chronic arthritis the specific data for maximal physical and mental well being through exercise, chronic therapeutic procedure, daily adaptation and confrontation in nursing intervention.

The Hwacheon-ri mineralized area is located within the Cretaceous Gyeongsang Basin of the Korean peninsula. The mineralized area includes the Hwacheon, Daeweon, Kuryong and Cheongryong mines. Each of these mines occurs along copper-bearing hydrothermal quartz veins that crosscut late Cretaceous volcanic rocks, although some disseminated ores in host rocks also exist locally. Mineralization can be separated into three distinct stages (I, II, and III) which developed along preexisting fracture zones. Stage I is ore-bearing, whereas stages II and III are barren. The main phase of ore mineralization, stage I, can be classified into three substages (Ia, Ib and Ic) based on ore mineral assemblages and textures. Substage Ia is characterized by pyrite-arsenopyrite-molybdenite-pyrrhotite assemblage and is most common at the Hwacheon deposit. Substage Ib is represented by main precipitation of Cu, Zn, and Pb minerals. Substage Ic is characteristic of hematite occurrence and is shown only at the Kuryong and Cheongryong deposits. Some differences in the ore mineralization at each mine in the area suggest that the evolution of hydrothermal fluids in the area varied in space (both vertically and horizontally) with respect to igneous rocks relating the ore mineralization. Fluid inclusion data show that stage I ore mineralization mainly occurred at temperatures between ${\approx}350^{\circ}$ and ${\approx}200^{\circ}C$ from fluids with salinities between 9.2 and 0.5 wt.% eq. NaCl. In the waning period of substage Ia, the high temperature and salinity fluid gave way to progressively cooler, more dilute fluids of later substage Ib and Ic (down to $200^{\circ}C$, 0 wt.% NaCl). There is a systematic decrease in the calculated ${\delta}^{18}O_{H2O}$ values with paragenetic time in the Hwacheon-ri hydrothermal system from values of ${\approx}2.7$‰ for substage Ia, through ${\approx}-2.8$‰ for substage Ib, to ${\approx}-9.9$‰ for substage Ic. The ${\delta}D$ values of fluid inclusion water also decrease with decreasing temperature (except for the Daeweon deposit) from -62‰ (substage Ia) to -80‰ (substage Ic and stage III). These trends are interpreted to indicate the progressive cooler, more oxidizing unexchanged meteoric water inundation of an initial hydrothermal system which is composed of highly exchanged meteoric water. Equilibrium thermodynamic interpretation of the mineral assemblages with the variation in amounts of chalcopyrite through the paragenetic time, and the evolution of the Hwacheon-ri hydrothermal fluids indicate that the solubility of copper chloride complexes in the hydrothermal system was mainly controlled by the variation of temperature and $fo_2$ conditions.

In order to study the occurrence of symptoms of musculoskeletal disorders of radio-technologists employed at metropolitan general hospitals and the factors that influence such occurrence, standardized questionnaire by NIOSH that was modified and supplemented to be suitable for conditions in Korea was used. Answers collected from 143 radio-technologists in two weeks from June 13, 2007 were analyzed and the results are as follows. Factor that influence symptoms of musculoskeletal disorders by area were analyzed through multiple logistic regression analysis and the results found that in the neck area, risk increased as the burdening work category 2(Korea ministry of labor)(OR=3.94) and burdening work category 9(Korea ministry of labor)(OR=4.72) increased. In the shoulder region, risk increased as burdening work category 2(Korea ministry of labor)(OR=5.36), burdening work category 7(Korea ministry of labor)(OR=3.90), and burdening work category 9 (Korea ministry of labor)(OR=5.76) increased. In the arm/hand/wrist regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=6.91), and burdening work category 9 (Korea ministry of labor)(OR=3.76) increased. In the lower back region, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.06), and burdening work category 8 (Korea ministry of labor)(OR=8.14) increased. In the leg/knees/foot regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.63), and burdening work category 9 (Korea ministry of labor)(OR=2.96) increased. Conclusively, in factors that influence musculoskeletal disorder symptoms in radio-technologists, influence of subjective health conditions, total work experience, experience in current division, and burdening work category 2, 7, 8, and 9 (Korea ministry of labor) were most significant. Therefore, for preventive management, in addition to ergonomic and educational intervention for correcting improper posture during work, efforts for break time adjustment and stress reduction is needed, and encouragement and support for regular exercise is needed.

This study was investigated the anti-angiogenic activities of Cnidium officinale Makino and Tabanus bovinus by using Chorioallantoic membrane (CAM) and rat cornea. First experiment, the fertilized chicken eggs were kept in a humidified egg incubator at $37^{\circ}C$. After 4 days incubation, about 3 ml of albumin was aspirated from eggs with an hypodermic needles through a small hole drilled at the narrow end of the eggs, and the shell membrane on the floor of the air sac was peeled away. Embryos with chorioallantois of 3~5 mm in diameter were employed for the assay of antiangiogenic activity. Retinoic acid was used as a positive control for this experiment. After 48 h of treatment. branching pattern of blood vessels below coverslip containing retinoic acid ($10{\mu}g/egg$) was dramatically decreased. A simiar angiogenic inhibition was observed in the CAM treated with $50{\mu}g/egg$ of Cnidium omcinale Makino and Tabanus bovinus extracts. Second experiment, rat corneal neovascularization was induced by suturing (one stitch) the cornea with 10-0 nylon, and terramycin was applied on the cornea for I week to prevent corneal inflammation. In the cornea of rats untreated with herbal extracts, numerous vessels were usually seen invading the cornea by day 2 or 3 after suture, and reaching the lesion area within 5~6 days. Corneal neovascularization was gradually increased and peaked at 3 weeks. In contrast to this, herbal extracts conspicuously inhibited the angiogenesis, Oral administration of herbal extracts (20 mg/kg body weight/day) for 4 weeks significantly inhibited the rat corneal angiogenesis induced by suture, and the length of blood vessels in herbal medicine-treated rat cornea was conspicuously lower than that in control animals. A similar phenomenon was also observed in the rat cornea treated with thalidomide (200 mg/kg body weight/day). These findings indicate the anti-angiogenic properties of Cnidium officinale Makino and Tabanus bovinus, suggesting that these properties may be one of the pharmacological mechanisms underlying the anti-tumor and anti-metastatic activities of herbal extracts tested in this study.

Cylindrical and conical types of grain-straw separation equipment which has a stationary crimped sieve drum with rotating inner rotor were constructed. The developed equipments were tested to investigate the characteristics of separating performance under various mechanical conditions and crop conditions. As increase of the inclination of equipment and decrease of pitch of cover vane, the grain recovery was increased while straw rejection was decreased. The grain recovery and overall efficiency were decreased as the rotor speed and feeding velocity were increased for both varieties of rice, moisture contents, and test equipments. Conical prototype equipment performed higher straw rejection, lower grain recovery, and lower power requirement. However, separation performance of conical type equipment was more widely varied with various test conditions compared to cylindrical one. The performance of both equipments showed relatively insensitive to crop feedrate and crop properties, such as variety, moisture content, and grain-to-straw ratio.

The present study was conducted to isolate Babesia gibsoni by culture method of the microaerophilous stationary phase(MASP) and analyse the antigenic properties of the parasite by SDS-PAGE and immunoblot. The results obtained were summarized as follows. The protozoan parasite Babesia gibsoni multiplied in canine erythrocytes in RPMI 1640 medium(pH7.0) containing 20 40% normal canine serum under the MASP condition of 5% CO2 and 95% air at $37^{\circ}C$ incubator. The levels of parasitaemia in the erythrocytes were shown more higher by exchanging the medium at 24 hours interval. Under the above condition of MASP, the percentage of parasitized erythrocytes(PPE) after incubation for 8 days increased about 14 times more than that in the initiation of the 1% infected canine erythrocyte culture. The parasites were purely isolated from the MASP culture of red blood cells collected from dogs infected with Babesia gibsoni naturally or artificially. Among the total of 36 canine(Pit-bullterier) blood samples the parasites were isolated from 17 cases(47.2%) in the MASP culture while the parasites were detected from 20 cases(56%) and 12 cases(33.3%), respectively, by indirect fluorescent antibody(IFA) test and direct light microscopy(DLM). On the other hand, Babesia gibsoni was isolated by MASP culture from 15 cases(75%) and 11 cases(92%) of positive cases of IFA and DLM, respectively. In the analysis of the erythrocytic merozoite(AEOM) antigen derived from infected dog approximately 11 antigenic bands in molecular weight of 130, 120, 97.4, 92, 80, 52, 50, 42, 36, 30 and 29 KDa were observed on SDS-PAGE. Antigenic bands in the endoerythrocytic merozoite(CEOM) antigen derived from infected erythrocyte (sediment) in MASP culture were much similar to those of AEOM bands. In the exoerythrocytic merozoite(CEEM) antigen derived from supernatant of the infected erythrocyte culture approximately 20 antigenic bands were observed and the molecular weight of the major bands among these were 140, 120, 114, 105, 96, 93, 92, 80, 60, 52, 50, 38, 36, 30, 24, 18.5 and 16 KDa. In the protein patterns of AEOM and CEOM antigen by immunoblot 15 bands were observed and these patterns were much similar between each other. The molecular weight of the major bands in the both antigens were 130, 120, 80, 60, 52, 50, 42, 30, 29, 18.5 and 16 KDa. Approximately 21 bands were observed in CEEM antigen and the molecular weight of the major bands were 140, 120, 96, 92, 85, 80, 76, 60, 52, 50, 37, 30, 24, 16 and 15 KDa. The specific antigenic bands in the artificially infected dogs were firstly observed at 3 weeks afrer inoculation of infected blood and these antigenic bands were maintained up to 18 months after inoculation. In the immunoblot of the sera of the splenectomized dogs the specific antigenic bands with the molecular weight of 93 KDa and 52 KDa, respectively, were observed weakly comparing to those of non-splenectomized dog. In immunoblot of the sera collected from the naturally infected dogs the antigenic bands were observed as same as those of artificially infected dogs while antigenic band of 29 KDa in some individual dog showed strongly. In comparison of immunoblot of the sera collected from dogs non-treated and treated with diminazene aceturate(7mg/kg, IM) after artificial infection no differences of antigenic bands were observed. In analysis of antigenic bands by digoxigenin glycan/protein double labeling, antigenic bands in the molecular weight of 106, 60 58, 36, 30 and 29 KDa were determined as glycoproteins.

As a result of analyzing the forming and the transformations of Seokjojeon Hall garden by linking it to the changes of Deoksugung Palace influenced by the social atmosphere, the Seokjojeon garden can be classified into four phases. The first phase starts from 1896 to 1914. Gyeongungung was built in the late 19th century(1896-1897) as an official palace and Junghwajeon Hall and Seokjojeon Hall was built for Gojong. J.M.Brown was in charge of the construction of Seokjojeon in the beginning but H.W.Davidson saw the end also set up the garden. In the process of forming the garden the incorporating of Dondeokjeon Hall and the demolishing of the west wing corridors of Junghwajeon Hall occurred. At this phase of the garden a statue of an eagle was put up in the garden but was soon taken down. The shape of the garden was quiet simple with a central axial pathway, a round assorted flower bed placed in front of Seokjojeon Hall. The second phase starts from 1915 to 1932 which lasted for 17 years. At the last years of the Great Han Empire the duties of Gungnaebu(宮內府) was transferred to Leewangjik(李王職) in 1911 and a research on the existing buildings was done by Jujeonkwa(主殿課) in 1915. According to the research drawings, the garden still maintained the axial pathway formed in the previous phase but the garden had an asymmetric form. The flower bed was formed in a round shape and an open-knot technique and boundary plantation was applied to the garden. The third phase starts from 1933 to 1937 and is the period when Seokjojeon Hall was made public. By the year of 1932 many buildings of Deoksugung Palace had been demolished in the preparation of the opening of Seokjojeon Hall as a permanent exhibition hall. The central axial pathway still remained in the new garden and added a pond with a turtle statue in the center. The fourth phase starts from 1938 until the liberation from Japan and is the period when Deoksugung Palace became a park. Yi Royal-Family Museum was built and linked to Seokjojeon Hall with a bridge and the garden transformed into a sunken garden. The garden adopted a fountain and a pagora. Despite the minor changes in the after years the garden still posses most of its form from the fourth phase. As we can see the current garden of Seokjojeon Hall is not the same as the initial garden and therefor the importance of this study lies in the fact that modifications to the statements regarding to Seokjojeon Hall garden should be made.

Die soeben entwickelten Grundgs$\ddot{a}$tze k$\ddot{o}$nnen dazu f$\ddot{u}$hren, dass es bei Fluggesellschaften zum Abschluss mehrerer Tarifvertr$\ddot{a}$ge $\ddot{u}$ber Personalvertretungen durch verschidene Gewerkschften kommt. Dies leitet schlie${\ss}$lich zu der bereits angesprochenen Problematik der Tarifkonkurrenz $\ddot{u}$ber. Tarifkonkurrenz zeichnet sich bekanntlich dadurch aus, dass f$\ddot{u}$r dasselbe Rechtsverh$\ddot{a}$ltnis dieselbe Regelungsmaterie durch mehr als einen Tarifvertrag geregelt wird. Eine solche Tarifkonkurenz kann unabh$\ddot{a}$ngig von der Frage, ob Regelungsgegenstand betriebsverfassungsrechtlicher Normen ein betriebliches Rechtsverh$\ddot{a}$ltnis ist, auch bei dieser Art von Tarifnormen auftreten. Dabei betriebsverfassungsrechtlichen Kollektivnormen gem$\ddot{a}{\ss}$ $\S$3 Abs. 2 TVG die Tarifbindung des Arbeitgebers f$\ddot{u}$r die Anwendungsbarkeit gen$\ddot{u}$gt, wird beim Vorhandensein mehrerer solcher Tarifvertr$\ddot{a}$ge h$\ddot{a}$ufig pauschal von einer in jedem Fall aufzul$\ddot{o}$senden tarifkonkurrenz gesprochen. $\ddot{U}$berschneiden sich die Geltungsbereiche mehrerer Tarifvertr$\ddot{a}$ge $\ddot{u}$ber personalvertretungsrechtliche Fragen der im Luftbetrieb t$\ddot{a}$tigen Besch$\ddot{a}$ftigten und handelt es sich nicht um textidentische Regelungen, f$\ddot{u}$hrt indes kein Weg daran vorbei, dass eine Tarifkonkurenz besteht, die einer Aufl$\ddot{o}$sung bedarf. Die Rechtsprechung hat sich zur speziellen Fragen der Aufl$\ddot{o}$sung einer Konkurrenz betriebsverfassungsrechtlicher Tarifnormen soweit ersichtlich noch nicht ge$\ddot{a}$u${\ss}$ert. Nicht zuletzt aus diesem Grund wird in der Literatur ein buntes Spektrum an L$\ddot{o}$sungen pr$\ddot{a}$sentiert, wobei sich die meisten neueren Stellungnahmen vor allem mit Organisationstarifvertr$\ddot{a}$gen im Sinne von ${\S}$3 BetrVG besch$\ddot{a}$ftigen.

This study performed to find proper temperature and improve texture and taste of pickle by considering physic-chemical characteristic and sensory evaluation. The basis temperature of the pickle was manufactured by 5 temperatures($95^{\circ}C$, $85^{\circ}C$, $75^{\circ}C$, $65^{\circ}C$, $5^{\circ}C$) at intervals of $10^{\circ}C$, and the dangerous Temp range was exempted during 12 days. Results showed that 3rd day at $95^{\circ}C$ was the best temperature for the quality specification of the pickle. In addition, between 6th to 12nd days at $85^{\circ}C$ and $95^{\circ}C$ appeared the most excellent preferences of the pickles. Thus, quality specifications showed different results by the date, and it appeared $95^{\circ}C>85^{\circ}C>75^{\circ}C>65^{\circ}C>5^{\circ}C$ in order. Furthermore, the liquid pickles at the temp of $95^{\circ}C{\sim}85^{\circ}C$ showed better texture and flavor of pickles as well as good preference. Based on these results, managers or administrators of foodservice business will be recognized the importance of temperature and storage period for salted pickles to improve its texture and taste along with improving quality and preference.

The purpose of this study was to find the optimal swelling method and condition for seacucumber to improve its taste and texture to accomodate the rapid increase of consumption. Another purpose was to try to determine an easy way to soak dried sea-cucumber under different conditions, and identify the influence of swelling time on the texture of sea-cucumber, in order to reduce preparation time and provide basic data for easy handling. After boiling or steaming for six different periods including 5, 15, 30 and 60 minutes the texture of the sea-cucumbers were compared, For the additive test, the sea-cucumbers were boiling for 30 minutes period with 4 different additives and the textures were compared, Since the texture is an important characteristic of sea-cucumber, there are many variables that affect this property including the, drying and preservation methods. This study provides basic understanding of the influence of the heating method, time and temperature on the swelling of sea-cucumber for handy use at processing sites.
