  • Statement of problem & Purpose: Articulators are very important for education and overall clinical situation in the field of prosthodontics, however preexisting articulators are designed and built based on maxillofacial structures and mean values of mandibular movement of Western people. Purpose of this research is to find out a adequate basis for applicating these articulators, presently used for clinical education, for Korean. Material and methods: 59 Korean adults (41 males, 18 females), aged between 24 to 41, where selected for this study. Two pairs of both maxillary and mandibular models were made for each examinee. These models where attached to both KaVo PROTARevo 7 and Hanau Modular semiadjustable articulators by using facebow transfer, than sagittal condylar inclination, occlusal plane inclination and position of mandibular on the articulator where measured. Result and conclusion: 1. Mean sagittal condylar inclination for KaVo PROTAR semiadjustable articulator was $33.75^{\circ}$(standard deviation $12.46^{\circ}$) meanwhile Hanau Modular semiadjustable articulator showed $40.72^{\circ}$(standard deviation $12.09^{\circ}$) for mean sagittal condylar inclination. 2. Mean occlusal plane inclination for KaVo PROTAR semiadjustable articulator was $-2.76{\circ}$(standard deviation $3.63^{\circ}$) meanwhile Hanau Modular semiadjustable articulator showed $11.87^{\circ}$ (standard deviation $3.63^{\circ}$) for mean occlusal plane inclination. 3. On the average center of the mandibular dentition were in the range of 5 to 7 mm of the central position of the articulator. Both anterior and posterior dentition were positioned at the center of the articulator vernacularly for KaVo PROTAR semiadjustable articulators, meantime for Hanau Modular semiadjustable articulator, anterior dentition was positioned 5 mm downwards and 3mm upwards for posterior dentition from vertically central position of the articulator.

  • Background: The research sought to identify the clinical features of pleomorphic carcinoma of the lung generally known as a rare subtype in accordance with the lung cancer classification done in 1999 by WHO. Material and Method: 250 cases of surgically resected lung cancers were collected in this hospital from January 1992 to December 2001. This study included 42 cases of pleomorphic carcinoma diagnosed through light microscope and immunohistochemistry. Result: Out of 42 cases, males represented 31, and females 11, the age ranged from 26 to 77. Main clinical symptoms included coughing, hemoptysis, sputum. Diagnoses disclosed the stage as stage la in 3 cases (7%), Ib in 16 (38%), IIa in 1 (2%), IIb in 8 (19%), IIIa in 15 (35%), and IIIb in 1 (2%). Out of these, no lymph node metastasis was represented in 23 cases (54%), while N1 and N2 involving lymph node metastasis was shown 19 cases (46%). A total of 19 patients developed metastasis, comprising the brain in 5 cases (26%), bone in 4 (21%), muscle in 4 (21%), Lymph node in 2 (10%), and 1 liver, ovary, contralateral lung, and adrenal gland, respectively. The size of the tumor ranged from 1 cm to 11 cm, averaging 5.85 cm. Out of the 42 patients, the total two-year and five-year survival rates in accordance with the Kaplan-Meier method represented 26% and 13%, respectively, These figures compared to the corresponding 44% and 34% in cases other than pleomorphic carcinoma from the survey target of 256 cases, proved to be significantly low (p<0.002). No significant difference was found in the survival rates compared between age and tumor size, between stage I and above stage II, and between N0 and above N1. Patients who developed postoperative metastasis all died, and showed significantly low survival rates (p<0.002) compared to those patients without metastasis. Conclusion: With the new diagnosis method of f999 WHO's lung cancer classification applied, pleomorphic carcinoma showed a higher prevalence rate than under previous classifications, their postoperative survival rate was significantly low compared to histologic type of non small cell lung carcinomas.

  • This study was conducted to investigate effects of farm, type of sow Landrace${\times}$Yorkshire, LY; Yorkshire${\times}$ Landrace, YL; Yorkshire${\times}$Yorkshire, YY and multi-cross bred sow, MBS), parity, farrowing year, farrowing season and mating method on reproductive traits such as total number born per litter, number of born alive per litter, number of weaned per litter, number of mummified per litter, number of stillbirth. The Reproductive Records of 3,387 litters from January, 1999 to September, 2002 were obtained from four pig farms managed by Electronic Data Processing(EDP) system. Reproductive performances for two types of F1 Sows(YL and LY) were estimated as 11.34${\pm}$0.266 and 11.57${\pm}$0.263 heads for total number of born per litter, 10.56${\pm}$0.216 and 11.81${\pm}$0.251 heads for number of born alive per litter, and 10.05${\pm}$0.131 and 9.96${\pm}$0.153 heads for number of weaned per litter, respectively. These records are significantly higher(P〈0.05) than those of YY and MBS. However, number of mummified per litter, number of stillborn per litter, number of dead by diarrhea per litter, number of dead by other reasons during lactating period per litter and estrus interval did not show significant difference between types of sows. There were more total number of born per litter and number of weaned per litter in year 2001 than other year. As year passed, number of dead by crush per litter, number of dead by diarrhea per litter and number of dead by other reasons during lactating period per litter reduced from 0.18${\pm}$0.023 to 0.07${\pm}$0.022 head, 0.12${\pm}$0.21 to 0.02${\pm}$0.020 head and 0.43${\pm}$0.041 to 0.22${\pm}$0.040 head, respectively and weaning rate increased from 0.94${\pm}$0.005% to 0.97${\pm}$0.005%. The total number of born per litter and number of born alive per litter were higher(P〈0.05) in the case of mating twice than mating once. The number of weaned per litter, number of mummified per litter and number of stillborn per litter were not significant(P〈0.05) between mating methods. Estrus interval was shorter on the occasion of twice artificial insemination(5.24${\pm}$0.153days) than twice natural mating(6.51${\pm}$0.466days).

  • The Pocheon iron (-copper) deposit, located at the northwestern part of the Precambrian Gyeonggi massif in South Korea, genetically remains controversial. Previous researchers advocated a metamorphosed (-exhalative) sedimentary origin for iron enrichment. In this study, we present strong evidences for skarnification and Fe mineralization, spatially associated with the Myeongseongsan granite. The Pocheon deposit is composed of diverse carbonate rocks such as dolostone and limestone which are partially overprinted by various hydrothermal skarns such as sodic-calcic, calcic and magnesian skarn. Iron (-copper) mineralization occurs mainly in the sodic-calcic skarn zone, locally superimposed by copper mineralization during retrograde stage of skarn. Age data determined on phlogopites from retrograde skarn stage by Ar-Ar and K-Ar methods range from $110.3{\pm}1.0Ma$ to $108.3{\pm}2.8Ma$, showing that skarn iron mineralization in the Pocheon is closely related to the shallow-depth Myeongseongsan granite (ca. 112 Ma). Carbon-oxygen isotopic depletions of carbonates in marbles, diverse skarns, and veins can be explained by decarbonation and interaction with an infiltrating hydrothermal fluids in open system ($XCO_2=0.1$). The results of sulfur isotope analyses indicate that both of sulfide (chalcopyrite-pyrite composite) and anhydrites in skarn have very high sulfur isotope values, suggesting the $^{34}S$ enrichment of the Pocheon sulfide and sulfate sulfur was derived from sulfate in the carbonate protolith. Shear zones with fractures in the Pocheon area channeled the saline, high $fO_2$ hydrothermal fluids, resulting in locally developed intense skarn alteration at temperature range of about $500^{\circ}$ to $400^{\circ}C$.

  • These days our nation is standing on tiptoe of welfare nation. so hospital in authority have done reformation to provide quality medical services. This effective nursing work to provide quality nursing by keeping pace with the reformation of management of hospital for quality medical function might be well said to be depending on the degree of function of nursing management of nursing department. This essay has been aimed to prepare the data to build the position of nursing organization which can elevate the quality of nursing by clarifying the difference of the degree of the function of nursing management according to the position of nursing department in hospital organization. 135 nurses of 1 general hospital in Seoul which has independent nursing organization of the hospitals of over 600 beds and 155 nurses of 1 general hospital in Seoul which has the nursing organization under the management of medical department have been the objects of this study. The tool of Yoon. Young Ae(1988) has been used by having it amended and complemented and the degree of reliability of the tool was resulted in Cronbach's Alpha .9155. The collected data have been analysed by SPSS program as mean. frequency, chi-square. t-test. F-test(ANOVA) and the results are as the follows; 1. Compared result of general characteristics of the two groups by $x^2$-test showed statistically significant difference between religion ($x^2$=10.375, p=.015) and educational background($x^2$=51.222. p=.000) 2. The t-test aimed to compare the degree of function of nursing management according to the position of nursing department is as the below: Compared result of the degree of the function of nursing management according to the areas has shown higher point in independent type(M=3.22) than in the type under the management of medical department(M=2.85) in the personnel and administrative activities of nursing department. the standard and regulation of nursing duty also showed higher point in independent than in the type under the management of medical department (M=3.37) and the education of nursing showed higher point in independent type(M=3.53) than in the type under the management of medical department(M=3.19) and the evaluation of nursing quality has shown higher point in independent type(M=3.33) than in the type under the management of medical department(M=3.05), The area which showed the highest difference of the degree of the function of nursing management between the two organizations was in the activities of personnel and administration management of nursing department (independent type M=3.22. the type under the management of medical department(M=2.85). The degree of function of general nursing management showed higher in independent type nursing organization than in the type under the management of medical department by 3.41 in independent type and 3.11 in the type under the management of medical department. The items which showed the lowest degree of function of nursing management of both organizations have been suitable nursing man power and distribution and the reflection of the opinion of nursing department. In conclusion. the degree of function of nursing management to be able to provide quality nursing for the hospital goal of quality medical works showed visibly higher in independent nursing organization than in the nursing organization under the management of medical department. Therefore it is desirable for the hospital to operate the nursing department in hospital organization by independent type rather than the type under the management of medical department and the chief of nursing department of the nursing organization of the type under the management of medical department should make effort to reform its structure to be able to establish the position of performing independent nursing management. And also the chief of the nursing organization of independent type should endeavor to build substantial independent type organization more than ever under the viewpoint of securing suitable nursing man power and the low degree of management in the reflection of the opinion of nursing department.

  • The nutritional compositions and antioxidative activities of the Kimcheon lowbush and Pyungtaek highbush blueberries cultivated in South Korea were investigated. The approximate compositions, pH, and soluble-solid and mineral contents of P, Ca, Mg, Na, and Zn were determined. Both blueberry cultivars had mainly fructose and glucose as free sugars while disaccharides such as sucrose, maltose, and lactose were not detected in both. Oleic, linoleic, and linolenic fatty acids were the major fatty acids in both types of blueberries. The total of 16 free amino acids, including seven essential and nine non-essential amino acids, were higher in the Pyungtaek highbush blueberry. Among the amino acids, arginine was especially much higher in the Pyungtaek highbush blueberry. The anthocyanin, resveratrol, and polyphenol compounds, which are the important biologically active compounds in blueberries, were found. The anthocyanin contents of the Kimcheon lowbush and Pyungtaek highbush blueberries were 22.0 and 18.1 mg/100 g, respectively; the resveratrol contents by HPLC, 0.12 and 0.11 mg/100 g; and the total polyphenol contents, 141.3 and 138.4 mg/100 g. The electron-donating ability determined based on the DPPH radical scavenging activity was increased in a concentration-dependent manner, and it was higher than that of the Pyungtaek highbush blueberries, which implies that it is highly correlated with the higher amounts of total polyphenol, anthocyanin, and resveratrol in it. In conclusion, the two varieties of Korean blueberries can be suggested as potential sources of high-value-added functional foods.

  • Background: Culture filtrate proteins secreted by mycobacteria are thought to play an important role in inducing protective immunity and to develop new methods for diagnosing tuberculosis. Methods: A culture filtrate protein of M. avium that was strongly reactive with goat antiserum against M. intracellulare was constructed. Its homologous protein (TB-14) in M. tuberculosis was cloned, expressed and purified. The inductions of IFN-${\gamma}$ stimulated with $10{\mu}g$ of TB-14 recombinant protein and $10{\mu}g$ PPD were estimated by using whole bloods from seven PPD (-) subjects, seven PPD (+) healthy volunteers and nine tuberculosis patients. Results: M. avium culture filtrate protein was confirmed as a hypothetical protein that was termed contig 116. A novel 14-kDa recombinant protein (TB-14) of M. tuberculosis was composed of 148 amino acids, including 30 amino acids of the signal peptide, and it showed 78% homology with M. avium. In the PPD (+) healthy volunteers, recombinant TB-14 protein strongly induced the secretion of IFN-${\gamma}$ in whole blood cultures. Conclusion: These results suggest that TB-14 recombinant protein might play an important role in inducing cell-mediated immunity against tuberculosis. Furthermore, TB-14 protein antigen and its antiserum will be available for the development of new diagnostic tools for tuberculosis.

  • The purpose of this study is to investigate the relation between social education and secondary education of seaside and sea village schools for supporting the successors to fishery. Objects of the study were five groups; 321 fishermen, 107 staff members of a Fishery Guidance Center, 1, 001 students, 306 teachers of sea villages, 193 staff members of a Fishery Cooperative Association. The total number of people being object of this study was 1, 876 persons. The questionaire used for this study was made after preliminary counseling with fishermen in sea villages and teachers in seaside schools. The results of this study are as follow ; 1) About the value of Fishery and successors to Fishery There have been more positive responses than negative ones to the question on the value of fishery. The main reason for positive responses lies in the potentiality for development of fishery but the negative responses are because of the heavy work. 56.8% of the respondents expected an increasing number of successor to fishery, but 43.2% of the respondents had a negative foresight on that problem. The negative respondents stated that the fisherman that moved from the sea villages to the urban areas are responsible for the none increasing numbers of successors to fishery. Most of the respondents answered that government support is needed in order to increase the number of successors to fishery. 2) Social education for Fishermen Only 40% of fishermen know the Fishing Village Guidance Center as the main institute for social education. 94.17% of the respondents prefer plural institutes to single ones. 5.9% of the respondents answered with opposit opinions. 40.4% of the respondents answered that technical teachings has not often been practised. The reason why technical teaching does not often come into effect are as follows; lack of technical expertise, insufficient concern of staff members of the Guidance Center or the Cooperation Association. Also fishermen answered that the Fisherman Guidance Center does not often practise technical education. The Fishery Cooperation Association with its social education for fisherman takes the role of education for the economical way and carries out financial assistance. The relationship between the Fishery Cooperative Association and fishermen is presented satisfactory. However, the frequency of education is not satisfactory. Indifferences between staff members of the Fishery Cooperative Association does not carry out fishery education very often. Also loaned money matters were not satisfactory. 3) Secondary education for Fishery This study showed that it is desirable that the practical course of middle schools in islets and seaside villages take education on fishery ; however, a few schools only take the practical course fishery. Most of the fishery high schools want computer education as a new recommendable course. The students of fishery high schools want computer education as a new recommendable course. The students of fishery high schools have problems with scientific terms in the text books for the practical of fishery high schools have problems with scientific terms in the text books for the practical courses. Over 80% of the respondents agreed that the principals of schools in islets and sea side villages should be men having majored in fishery. 4) The connection between social education and secondary education for fishery a. It is desirable that the principal and vice principal of secondary schools in islets and sea side villages are men majored in fishery. b. It is recommendable that fishery courses are taken as practical courses in fishery village schools for it is helpful to relate between the vocation and the district's special character, as well as to built up relation between the middle school education and the fishery high school education. c. The teachers of fishery high schools and the officials of government offices which are related to fishery should work together to realize a program on teaching various kinds of techniques and give other useful informations to fishermen. d. During the vacations the fishery high school could be used for the social education of fishermen. Seminars on fishery technique and cultural aspects could be held. Especially a spiritual education which is needed for the improvement of the society of fishermen could be achieved by a cultural education. e. On the state level a financial support to raise the number of successors to fishery, a national policy for the betterment of the life of fishermen, as well as active publicity activities are necessary. f. A financial support of the government for raising the number of the successors to fishery is needed. For this purpose a fishery education performed on a state level would be desirable.

  • To reduce phosphorus and nitrogen from the swine wastewater, magnesium chloride $(MgCl_2)$ was used as a reaction material for both soluble phosphorus (SP) and ammonia-nitrogen (AN). The initial value of SP content were $471mg/\ell$ far aeration test and $515 mg/\ell$ for NaOH addition test, but treatment of $MgCl_2$ reduced SP value to $5mg/\ell$ and $4mg/\ell$. The removal efficiency of $MgCl_2$ for SP showed $99\%$ in both treatment, and the removal efficiency of $MgCl_2$ for AN showed $15\%$ with treatment of aeration and $18\%$ with NaOH. All the experiments were done in a low temperature of 6 to $8^{\circ}C$, suggesting that this methods are possibly able to apply to a cold weather conditions. Moreover, the struvite crystal structure was identified by electronic microscope, implying that $MgCl_2$ is an effective material for removal of SP from swine wastewater In addition to the increased removal rate of the AN in wastewater, both $MgCl_2$ and $KH_2PO_4$ were added. The SP value was reduced by $99\%$ with 2g addition of the phosphate. The SP removal rate by 4g addition of the phosphate was increased only as $15-19\%$, but the quantity of removed SP was higher than that of 2g addition test. The value of AN was not reduced as expected by adding $KH_2PO_4$. The AN removal rate were low as $18\%$ and $15\%$ like as the level of the former test with $MgCl_2$ alone. Therefore, it is needed to examine closely the reaction mechanism f3r reducing both SP and AN simultaneously.

  • This experiment has been made to study the relationship between several characters affecting the field lodging and to establish some useful standards for selection of lodging resistant varieties and to classify the degree of lodging resistance in wheat and barley varieties of different sources. The experiment was carried at the Crop Experiment Station, Suwon in 1968. The results obtained are summarized as followings. a. The lodging index modified with bending moment of culm at breaking seemed to be the most useful character in checking the lodging resistance. Highly significant positive correlation (Barley; r=0.40-0.67, Wheat; r=0.46-0.68) was obtained between the lodging index and actual field lodging. b. Between two essential components expressing bending stiffness of the culm, the bending moment at breaking and secondary moment of inertia, a highly significant positive correlation (Barley; r=0.59, wheat; r=0.46-0.53) was observed. c. The bending stiffness of culm got stronger as the dry weight per unit culm, which express the quantity of accumulated dry matters in culm, increased. The correlation coefficient between those two factors was 0.35 to 0.40 in barley and 0.33 to 0.76 in wheat respectively. d. In both wheat and barley, highly significant negative correlation between lodging index and the other factors such as dry weight per unit culm (Barley; r=-0. 51 to -0.70, Wheat; r=-0.65 to -0.83) and bending moment of culm at breaking (Barley; r=-0.29 to -0.69, Wheat: r=-0.54 to -0.89) were observed. Particulary, weight of culm at breaking, secondary moment of inertia and section modulus showed significant negative correlation with lodging index in wheat. e. Outside diameter of culm expressed more intimate relationship with physical characteristics of culm than inside diameter and also showed highly significant correlation with weight of culm at breaking (Barley; r=0.42-0.56, Wheat; r=0.39-0.44) and with bending moment of culm at breaking (Barley; r=0.40-0.41, Wheat; r=0.38-0.49) and with secondary moment of inertia (Barley; r=0.56-0.57, Wheat; r=0.28-0.98) and with section modulus (Wheat; r=0.22-0.96). Between the thickness of culm and physical characteristics of culm also showed the positive correlation. f. There was positive correlation between the culm length and actual field lodging in several groups of variety among the varieties tested. But the culm length seemed to undesirable as a selection measure for the selection of the lodging resistant variety considering the stiffness of culm. g. In classification of lodging resistance for the varieties tested, many Korean barley varieties expressed excellent lodging resistant than wheat, but most of the wheat and barley varieties from Japan considered quite resistant to lodging. h. In selection of lodging resistant varieties, lodging index lower than 1.67 in barley and 1. 76 in wheat considered highly resistant to actual field lodging.
