Purpose: All acts which are enforced from the radioactive iodine therapeutic team is a in its own way principle and provision. Therefore unification of all acts can not be appropriately. We will make the standard coherence. Materials & Methods: From 5 November, 2007 to 17 November 2007, we conducted a questionnaire survey of the nuclear medicine manager of 30 hospitals. The contents of a questionnaire is medical treatment section, patient management, prosecuting attorney section, waste management and safety supervision in about the patient and a questionnaire was drawn up in the method which selects an item. Results: 30 hospital agencies are operating purely for I-131 high dose ablation therapy. Diagnostic study and daily schedule had the difference of some. The most of education for the patients took charge of doctor and nurse. The satisfaction of education was evaluated as the high thing. The safety supervision of waste management accomplishment and Safety supervision the patient and the worker observed on the basis of atomic energy law. Conclusion: Specific standards with sufficient amount of information and practical contents should have been presented through the following data. However, it seems to be lacking in many aspects. Nevertheless, respondents rated 70.9%, which is relatively high, on the value of clinical utilization, and I am very thankful for the evaluation. For many years from now, it may seem necessary for a lot of research on the specific matters based on these data to be conducted.

This study was conducted to estimate the growth curve parameters of crossbreds between Korean native boars and Landrace sows and their relationships with meat qualities. The data used were weight-age data and carcass data from 131 males and 122 females raised at N.L.R.I in Korea. Growth curve parameters were estimated from nonlinear regression using Gompertz model individually. Average mature weight(A), average maturing rate(k), and average inflection point(u) showing maximum growth rate estimated were 179.54${\pm}$6.06kg, 0.3154${\pm}$0.0059, and 5.50${\pm}$0.11 months in females, and 179.84${\pm}$6.33kg, 0.3049${\pm}$0.0061, and 5.24${\pm}$0.13 months in males, respectively. For the growth curve parameters and derived statistics, the phenotypic correlations of maturing rate with gain rate at inflection, mature weight, and inflection point were - .30, - .77, and - .93 in male, and - .31, - .78 and - .94 in female, respectively. Matrure weight was positively correlated to the inflection point as + .89 in both male and female, indicating that late maturing pigs with lower k had longer maturing period with increasing gain rate and reached point of inflection later than early maturing pigs with higher k, and grew to larger mature weight. Backfat thickness and erode fat contents were correlated with mature weight positively in male and negatively in female, and correlated with gain rate at inflection point positively in both male and female, of which coefficients were as high as .42 and .50 in male, respectively.

Experimental and numerical studies were conducted to investigate the thermal and chemical characteristics of heptane fires in a full-scale ISO 9705 room. Representative fire conditions were considered for over-ventilated fire (OVF) and under-ventilated fire (UVF). Fuel flow rate and doorway width were changed to create OVF and UVF conditions. Detailed comparisons of temperature and species concentrations between experimental and numerical data were presented in order to validate the predictive performance of FDS (Fire Dynamic Simulator). The OVF and UVF were explicitly characterized with distributions of temperature and product formation measured in the upper layer, as well as combustion efficiency and global equivalence ratio. It was shown that the numerical results provided a quantitatively realistic prediction of the experimental results observed in the OVF conditions. For the UVF, the numerically predicted temperature showed reasonable agreement with the measured temperature. The predicted steady-state volume fractions of $O_2$, $CO_2$, CO and THC also agreed quantitatively with the experimental data. Although there were some limitations to predict accurately the transient behavior in terms of CO production/consumption in the UVF condition, it was concluded that the current FDS was very useful tool to predict the fire characteristics inside the compartment for the OVF and UVF.

Si on examine le bilan 2014 du CNC en France et celui du KOFIC en Corée du Sud, on peut s'apercevoir que l'éhelle industrielle cinématographique des deux pays est très similaire. On peut découvrir quelques chiffres à propos des résultats de l'industrie cinématographique dans ce bilan comme le nombre d'entrées, la recette des guichets, le nombre de production qui sont très similaires. La part de marché pour les films nationaux des deux pays augmente fortement en 2014. Mais ces chiffres de marché pour les films nationals sont les résultats obtenus dans les situations trés différentes des deux pays. En ce cas, la différence entre les deux pays vient d'où? Il en résulte de la politique de la culture cinématographique pour 'la sensibilisation du film comme une culture' des deux pays. Ceci est la partie la plus importante de la différence, qui est également visible dans la politique de la culture de France et de Corée du Sud. Depuis quelques années, le cinéma coréen se développe considérablement, à l'intérieur comme à l'extérieur du pays. Cependant, ce succès masque un certain déséquilibre de l'industrie cinématographique. On se rend compte également de la concentration du pouvoir par la monopolisation des grandes entreprises qui fonctionnent selon le principe de l'intégration verticale, et qui contrôlent toute la chaîne du marché cinématographique, de l'investisse111ent à la diffusion en passant par la production et la distribution. Il est impossible de trouver une solution dans des conditions défavorables où le phénomène du fort accaparement de l'industrie cinématographique coréenne est couplé avec à une logique industrielle de libéralisation du marché. Pour résoudre la monopolisation de l'industrie cinématographique coréenne, qui pose des problème décisifs et partials sur le marché, il va falloir une politique équilibrée de la promotion de la culture cinématographique menée par le KOFIC (Korean Film Council) qui est une organisation financée par le gouvemement. On voudrait proposer une politique de la culture cinématographique qui serait adaptée à la politique du cinéma de la Corée du Sud, à travers des recherches sur la situation actuelle ainsi que l'analyse comparée cles politiques du cinéma entre Corée du Sud et France.

After studing of viewpoint of surgical disease in seven medical books related with Ju Dan Gye(朱丹溪) among four eminent physicians in the Jin and Yuan dynasties(金元四大家) I get conclsion as following. 1. Studied surgical diseases are total 40 kinds. 2. In 40 kinds surgical diseaes, case of having theory are 20 kinds, cases of having no theory and having only treatement by medicine are 20 kinds. 3. In therapy, cases that mainly use a method to eliminate pathogenic factors are 27 kinds; Acute mastitis(乳癰), Deep-seated mammary abscess(내巖), Acute appendicitis(陽癰), Bone cellulitis(附骨疽), Carbuncle of the lower abdomen near external genitalia(便毒), Leprosy(癩風), Macule(斑), Rash(疹), Urticaria(은疹), Scrofula(나역), Stagnant plegm(結核), Goiter andtumer(영유), Erysipelas(丹), Furuncle(정瘡), Scabies(疥瘡), Chancre(下疳瘡), Syphilitic skin disease(樣梅瘡), Incised wound (金瘡), Dermatopathy of lower limb and heel(脚足部瘡), Pemphigus(天疱瘡), Itching eruption due to blood-heat or wind heat(血風瘡), Dermatopathy of head(頭面瘡), Scald and burn(湯火瘡), Tetanus(破傷風) , Ecthyma(염瘡), Fistula(久漏瘡), Tinea(癬瘡), Cases that mainly use external therapy are 5 kinds; Rhagades of hand and foot(手足군裂), Vulvar ulceration(婦人陰瘡), Chilblain(凍瘡), Rabies(풍狗咬), Tinea capitis(白禿瘡), Cases that mainly use a reinforcing method are 4 kinds; Internal deep-rooted carbuncle(內疽), Pruritus and dryness of skin(皮膚乾燥), Anul fistula(漏瘡), Macule Caused by disorder of internal organ(內傷發斑), Cases that mainly use eliminating first and then reinforcing are 2 kinds; Pyogenic infection and ulcerous disease of slin( 疽瘡상癰疽瘡瘍), Lung abscess(肺癰), Case that mainly uses reinforcement and elimination in combination is only Haemorroid(痔瘡). Case divided into two groups that are reinforcing method and a method to eliminate pathogenic factor is only Trauma(打撲). Case that have no treatment by medicine is only Abscess of the scrotum(囊癰). 4. In 40 kinds surgical diseases, we can know that except a few important surgical diseases, Ju Dan Gye haven't distinguished viewpoint in many surgical diseases, because there are many cases that have no theory and have only simple treatment of medicine, and that mainly use a method to eliminate pathogenic factors and external therapy. 5. Representative theory of Ju Dan Gye, nourishing Yin and extinguishing fire(滋陰降火), has little effect on therapy of surgical disease. We need to try statistical division of internal and external remedy in the future, and by studing of surgical disase in medical books related with four eminent physicians in the Jin and Yuan dynasties, I think we can see their viewpoint of surgical disease.

Late Cretaceous (90.5 Ma), epithermal gold-silver vein mineralization of the Weolseong and Samchang mines in the Sulcheon area, 60 km southeast of Taejeon, can be separated into two distinct stages (I and II) during which fault-related fissures in Precambrian gneiss and Cretaceous (102 Ma) porphyritic granite were filled. Fluid inclusion and mineralogical data suggest that quartz-sulfide-electrum-argentite-forming stage I evolved from initial high temperatures $({\approx}340^{\circ}C})$ to later lower temperatures $({\approx}140^{\circ}C})$ at shallow depths of about 400 to 700 m. Ore fluid salinities were in the range between 0.2 and 6.6 wt. % eq. NaCl. A simple statistic model for fluid-fluid mixing indicates that the mixing ratio (the volumetric ratio between deep hydrothermal fluids and meteoric water) systematically decreased with time. Gold-silver deposition occurred at temperatures of $230{\pm}40^{\circ}C$ mainly as a result of progressive cooling of ore-forming fluids through mixing with less-evolved meteoric waters. Measured and calculated hydrogen and oxygen isotope values of hydrothermal fluids indicate meteoric water dominance, approaching unexchanged meteoric water values. The geologic, mineralogic, and geochemical data from the Weolseong and Samchang mines are similar to those from other Korean epithermal gold-silver vein deposits.

This experiment was conducted to test the effect on germination and seedling growth of major industrial crops and weed control potential using alfalfa plant. When dried alfalfa residues were mixed into vermiculite, germination, length of shoot and root of crops, such as Perilla frutescens, Sorghum nevosum, Platycodon grandiflorum and weeds, Digitaria saguinalis, Setaria viridis, Siegesbechia pubescens, Ammaranthus lividus, and Solanum nigrum, were significantly inhibited as the dried residue concentration increased. More than 10% concentration of the dired residue caused 80% germination and growth inhibition. The fresh alfalfa exudation also inhibited the germination and seedling growth of crop, barley, rye, alfalfa, and sesame, and weeds, Echinochloa crus-galli, Siegesbechia viridis, and Portulaca oleracea. The degree of inhibition showed the different response according to the fresh exudation concentration, types of crops and weeds. Generally, as the exudation concentration increased, the germination and seedling growth of crops and weeds inhibited. The exudation of dried residue also exhibited the strong inhibition effect on germination and seedling growth of crops, alfalfa, Platycodon grandiflorum, barley, sesame, rye and weeds, D. sanguinalis, S. pubescens, S. viridis, P. oleracea, E. crus-galli, At the 10% concentrations, S. pubescens, and P. oleracea were not germinated and showed only 15% germination in the S. viridis. From this study, would conclude that alfalfa plant contained water soluble phytotoxic substances which were inhibitory to weeds and crops. This results suggest that alfalfa had some possibility to control some weed species using toxic compounds like natural herbicide.

For the Rapid detection of small hive beetle (SHB; Aethina tumida) and for the mass-survey against SHB invasion, SHB-specific ultra-rapid PCR system was developed. Three different pairs of Aethina tumida-specific primers were deduced from cytochrome oxidase subunit I (COI) gene in mitochondrial DNA of SHB. Using optimized SHB-specific ultra-rapid PCR, $2.1{\times}10^1$ molecules of COI gene belonged to SHB could be detected specifically and quantitatively within 18 minutes 40 seconds. For the purpose of the application in apiary field, a DNA extraction method from bee debris was separatedly developed. When $10^5$ SHB-specific COI molecules (1/1000 body of SHB larvae) are existed in 1g of bee debris, it could be verified inner 10 minutes as qualitative and quantitative manner. SHB-specific ultra-rapid PCR we proposed would be expected to apply widely, either in apiary field or laboratory, for the rapid detections and the control against SHB-invasion.

We sought to confirm an independent factor about in-stent restenosis (ISR) in the patients who underwent drug-eluting stent (DES) and know a possibility as a predictor of measured coronary artery calcium score by MDCT. A total of 178 patients (159 men, $61.7{\pm}10.0$ years of age) with 190 coronary artery lesions were included in this study out of 1,131 patients who underwent percutaneous coronary intervention (PCI) with DES implantation for significant stenosis on MDCT at Chonnam National University Hospital between May 2006 and May 2009. All lesions were divided into two groups with the presence of ISR : group I (re ISR, N = 57) and group II (no ISR, N = 133). Compared to group II, group I was more likely to be older ($65.8{\pm}9.0$ vs. $60.2{\pm}9.9$ years, p = 0.0001), diabetic (21.8% vs. 52.6%, p = 0.0001), have old myocardial infarction (8.8% vs. 2.3%, p = 0.040), left main stem disease (5.3% vs. 0.8%, p = 0.047), and smaller stent size ($3.1{\pm}0.3\;mm$ vs. $3.3{\pm}0.4\;mm$, p = 0.004). Group II was more likely to be smokers (19.3% vs. 42.1%, p = 0.003), have dyslipidemia (8.8% vs. 23.3%, p = 0.019). Left ventricular ejection fraction, lesion complexity, and stent length were not different between the two groups. Total CAC score was $389.3{\pm}458.3$ in group I and $371.2{\pm}500.8$ in group II (p = 0.185). No statistical difference was observed between the groups in CAC score in the culprit vessel, left main stem, left anterior descending artery, left circumflex artery, and right coronary artery. On multivariate logistic regression analysis, left main stem disease (OR = 168.0, 95% CI = 7.83-3,604.3, p = 0.001), male sex (OR = 36.5, 95% CI = 5.89-2,226.9, p = 0.0001), and the presence of diabetes (OR = 2.62, 95% CI = 1.071-6.450, p = 0.035) were independent predictors of ISR after DES implantation. In patients who underwent DES implantation for significant coronary stenosis on MDCT, ISR was associated with left main stem disease, male sex, and the presence of diabetes. However, CAC score by MDCT was not a predictor of ISR in this study population.

Purpose : The P1 protein of Mycoplasma pneumoniae mediates the attachment of the pathogen to its host cell and elicits a strong humoral immune response during infection with this organism. Mycoplasma pneumoniae strains can be classified into two groups(I and II) by PCR method of P1 cytadhesin gene. In this study, we evaluated the prevalence, epidemiological and clinical characteristics of each group. Methods : From 155 patients with Mycoplasma pneumoniae, who admitted to the Department of Pediatrics, Sung-Ae and Kwangmyung Sung-Ae Hospital between November 1996 and October 1997, we collected their throat swabs or nasopharyngeal aspirates for DNA extraction and serum for indirect hemagglutination test of Mycoplasma pneumoniae. The group specific PCR amplification were performed using specific oligonucleotide primers designed for P1 gene genotyping. Results : Group I(137 patients, 88.4%) occurred frequently than group II(18 patients, 11.6%). In both group, the most prevalent season was winter in 1996(Nov. to Dec.) and fall in 1997(Aug. to Oct.) The prevalent age was four to six years old. The number of male was more than female in both group; Group 1(1.2:1), Goup 2(1.6:1). No significant relationship were found between two groups in duration of fever and hospital days(P>0.05). The rate of high antibody titers(>1:5120) was lower in group I(6/137, 4.4%) than group II(2/18, 11.1%). Conclusion : Group I was much more prevalent than group II during 1996~1997 in Korea. There was no difference between two groups in epidemiological and clinical parameters except the rate of high antibody titers. Further follow-up survey will be needed for the epidemiologic and clinical studies of Mycoplasma pneumoniae in Korea.
