The purpose of this study was to examine the toothbrushing behavior of the citizens, their use of dentifrice, awareness of the importance of dentifrice purchase and consciousness of dentifrice containing the extract of Chamaecyparis obtusa in the city of Gwangju. It's basically meant to provide some informations on the development of oral health supplies involving dentifrice containing the extract of Chamaecyparis obtusa in that city in an effort to help the city serve as a hub of the dental industry. The subjects in this study were the selected citizens in the city of Gwangju. As a result of analyzing their awareness of the importance of the considerations for the purchase and use of dentifrice, they gave 68.2% overall. They gave the highest marks of 83.3% to the importance of effect. As for the importance of each item, they gave the highest marks of 85.1% to the importance of the prevention of dental caries. Concerning differences in awareness of the importance of the external purchase factors according to age, every age group placed the most importance on inspection by the certification authorities except for those who were in their 40s and 60s, and the respondents who were in their 40s and 60s attached more importance to price than the other items. Regarding differences in awareness of the importance of effectiveness according to age, those who were under the age of 20 gave the highest marks of 79.8% to the importance of dental-caries prevention and whitening effects. As a result of asking them whether they had an intention to use dentifrice containing the extract of Chamaecyparis obtusa if this dentifrice would be developed, 54.6% replied they had the intention. When they were asked another question whether they thought this dentifrice would have an effect on oral health, 55.1% answered they thought so. 33.8% expected this dentifrice to have a primary effect on the prevention of dental caries. Given the findings of the study, full-scale R&D efforts should be directed into the development of dentifrice containing the extract of chamaecyparis obtusa in the future.

In dieser Arbeit ist zum ersten allgemeiner $\ddot{U}$berblick auf die Verschuldensprinzip, das grunds$\ddot{a}$tzlich f$\ddot{u}$r die Unfalls-Haftung im Bereich der medizinischen Behandlungsfehler noch immerhin gelten, in aller K$\ddot{u}$rze angef$\ddot{u}$hrt und zugleich in rechtsvergleichender Weise auf die sozialrechtliche Typenentwicklung in Bezug auf die haftungsrechtlich motivierte Entsch$\ddot{a}$digung. Gem$\ddot{a}{\ss}$ dem ${\S}$ 46 Gesetzes zur Abhilfe f$\ddot{u}$r medizinische Besch$\ddot{a}$digungenund auf die Mediation-Schlichtung f$\ddot{u}$r medizinische Streitigkeiten ist die rechtssystematische Bedeutung des Kompensations-Zusicherungsgeschafts als eine Art institutioneller Fremdversorgung zu erfassen. Demzufolge geht es h$\ddot{a}$uptsachlich um die Problematik von tatbest$\ddot{a}$ndlichen Merkmalen der Kompensation im ${\S}$ 46 obigen Gesetzes (unten 1) und im Bezug auf die im voraus von GF-Ministerium bekanntgegebene AO (provisorische Fassung) von 8. 11. 2011. um die Analyse einer Reihe von KHG-Entscheidungen $\ddot{u}$ber $\ddot{a}$rztliche Geburtsbehandlungsfehler (unten 2). Dabei ist noch die Geltungsbereich mit entsprechendem Kompensationssystem in Japan zu vergleichen (unten 3). 1. Der terminologische Sinn von "h$\ddot{o}$here Gewalt" ist sowohl semantisch wie auch juristisch-rechtstechnisch eine negative Vorausaussetzung f$\ddot{u}$r haftbar machende Gef$\ddot{a}$hrdungstatbestand. Nicht nur im Inhalt und Umfang vertr$\ddot{a}$gt dieser Rechtsbegriff sich nicht mit dem anderen tatbest$\ddot{a}$ndlich parallell zu erf$\ddot{u}$llenden Merkmal, also "die Besch$\ddot{a}$digung aus unverschuldeter $\ddot{a}$rztlicher Geburtsvorsorge", weil die jene enger als die diese auf dem Begriffsfeld ist, sondern auch im dogmengeschichtlichen, auch doch rechtstechnichen Sinne ist die Terminologie von "h$\ddot{o}$here Gewalt" ungeeignet, f$\ddot{u}$r den kompensatorischen Tatbetand als ein positives Merkmal, zu sein, statt derer, m. E. sollte der Begriff von "unkontrollierbarer Zuf$\ddot{a}$lligkeit" als L$\ddot{o}$sungsansatz verwendet werden. Dazu ist auch die ratio legis zur institutionellen Einf$\ddot{u}$hrung des obigen Kompensations-Zusicherungsgesch$\ddot{a}$fts, das sich auf die Entsch$\ddot{a}$digung des f$\ddot{u}$r Patienten unertr$\ddot{a}$glichen Verlustes gerichtet, d. h. gerade die Augabe des nachteilsausgleichenden Einstehens f$\ddot{u}$r Ungl$\ddot{u}$ck, nicht f$\ddot{u}$r Unrecht, zu ber$\ddot{u}$cksichtigen. 2. Die Typen der KHG-Entscheidungsf$\ddot{a}$llen im Bereich von Gyn$\ddot{u}$kologie k$\ddot{o}$nnten diagnostisch bzw. therapeutisch im folgenden differenziert sein werden; je nach der Kriterien von der Weise und dem Zeitpunkt zur Geburtshilfe, technischen Behandlungsfehlern beim Geburtsvorgang, und Besorgungsfehlern nach dem Geburt u. dgl. 3. Die japanische verschuldensunabh$\ddot{a}$ngige Kompensation ist eigentlich eine Art institutionelle Vorsorge, die anders als koreanische Versorgungssystem auf Grund privatsicherungsfinaler Vorleistung gew$\ddot{a}$rleistet wird. Der kompensatorische Bereich beschr$\ddot{a}$nkt sich auf die schwere infantile Zerebralparese (Cerebralparese) beim medizinischen Geburtsbehandlung. Schlie${\ss}$lich w$\ddot{u}$rde diese Arbeit erw$\ddot{u}$nscht sein, zur Konkretisierung des Voraussetzungen f$\ddot{u}$r die Kompensation nach ${\S}$ 46 Abs. 1 u. 4 des obigen Gesetzes beitragen zu k$\ddot{o}$nnen, welcher spatestens am 8. 4. 2013. zur Geltung gebracht sein sollte.

The infestation rates and abundances of human infecting metacercariae (Clonorchis sinensis, Metcgonimus spry. , Centrocestus crmatus, Echinostoma hortense, Echinochusnus japonicw, Clinostomum complanctum) in freshwater fish were investigated at the three river areas - Taewhagang (river), Hyongsangang (river), Nakdonggang (river) - in Kyongsang-do and at four streams - Yonpungchon, Munsanchon, Kyonganchon, and Konjiamchon- in Kyonggi-do, Korea in 1994-1995. The fish caught at Taewhagang were heavily infested with metacercariae of Clonorchis sinensis and Centrocestw armctus. At Hyongsangang, Zncco platypus and Z. temmincki were moderately infested with metacercariae of C. crmctus. Chomanpo, at the basin of Nakdonggang, was still endemic for C. sinensis. In the fish caught at four streams of Kyonggi-do, metacercariae of C. sinensis exhibited the highest infestation rate and intensity out of 6 species of metacercariae. The infestation intensity of C. sinensis metacercariae in fish flesh was markedly different according to each division of flesh. The cause of this difference was conjectured as a result of larval behavior. The metacercariae of C. omnt5 were found in almost all parts, except scales and fins, of fish. The infestation rates and intensities of C. sinensis and C. armntus metacercariae in Taewhagang greatly increased as compared with those of previous reports . RhinoBobius bmnneus and Aconthorhone5 macropterus are newly recorded intermediate hosts of Echinostonn hortense. The reason of large differences from previous data was discussed and the standard method of metacercaria examination was proposed.

A simplistic quality assurance (QA) method was designed for a Linac built-in enhanced dynamic wedge (EDW), which can be utilized to make wedged beam distributions. For the purpose of implementing the EDW symmetry QA, a film dosimetry system, low speedy dosimetry film, film densitometer and 3D RTP system were used, and the films irradiated by means of a 60$^{\circ}$ Reversed wedge pair (REWP) method. The profiles were then analyzed in terms of their symmetries, including partial treatment, which is the case of stopping it abruptly during EDW irradiation, and the measured and calculated values compared using the Cad Plan Golden Segmented Treatment Table (Golden STT). The result of this experiment was in good agreement, within 1 %, of the 'reversed wedge pair counterbalance effect'. For the QA of the effective wedge factor (EWF), the authors measured EWFs in relation to the 10$^{\circ}$, 15$^{\circ}$, 20$^{\circ}$, 25$^{\circ}$, 30$^{\circ}$, 45$^{\circ}$ and 60$^{\circ}$ EDW, which were compared with the calculated values using the correction factor derived from the Golden STT and the log files produced automatically during the process of EDW irradiation. By means of this method it was capable of check up the safety of effective wedge factor without any other dosimetry system. The EDW QA was able to be completed within 1 hour from irradiation to analysis as a consequence of the simplified QA procedure, with maximized effectiveness. Unlike the metal wedge system, the EDW system was heavily dependent on the dose rates and jaw movements; therefore, its features could potentially cause inaccuracy. The frequent simplistic QA for the EDW is essential, and could secure against the flaw of dynamic treatment that uses the EDW.

Telomeres are essential for chromosome stability and are related with cell senescence, apoptosis and cancer. Even though telomere length and telomerase activity have been studied extensively, very little is known to analyze the telomere dynamics in chicken cells. This study was carried out to analyze the telomere distribution and telomerase activity of Korean Native Chicken cells along with aging. The cells were collected from brain, heart, liver, kidney and germinal tissues during physiological stages. Telomere distribution was analyzed by Quantitative-Fluorescence in situ Hybridization (Q-FISH) techniques using the chicken telomeric DNA probe. Telomerase activity was performed by Telomeric Repeat Amplification Protocol (TRAP) assay. In results, the telomeres of chicken were found at the ends of all chromosomes with the interstitial telomeres on chromosomes 1, 2 and 3. The amount of telomeres on chicken cells was decreased along with aging in most tissues. Furthermore, the telomere quantity was significantly different among tissues. The relative amount of telomeres in proliferous cells such as testis cells had much more than those of liver, brain, heart, blood and kidney cells. The telomerase activity was down-regulated in cells of brain, heart and liver tissues. Whereas gonadal cells showed a constitutive activity of telomerase during all stage of life. In conclusions, the telomere quantity and telomerase activity in chicken are closely relate to cell proliferation and tissue specificity during developmental stages and aging. There is also closely correlated between the amounts of telomeric DNA and telomerase activity in chicken tissues.

To examine the effects of dietary organic selenium and vitamin E supplementation on egg production, egg weight, daily egg mass, feed intake, feed conversion, egg quality, lipid-soluble antioxidative capacity (ACL) in egg yolk, and selenium retention of egg in laying hens, Hy-Line laying hens of 77 wk old were replaced in the individual cage for 12 week. A corn-soybean meal based diet was supplemented with 0 (control), vitamin E 100 IU/kg and the combination of 0.9 ppm Se from selenium yeast (SY) and vitamin E 50, 100 and 150 IU/kg. Egg production and daily egg mass were significantly increased (P<0.05) in supplemental vitamin E 100 IU, and 0.9 ppm SY + vitamin E 50 IU than control for the whole experimental period. However, feed intake and feed conversion were not affected by supplemental vitamin E and SY. Haugh unit was significantly (P<0.05) higher in supplemental vitamin E 100 IU and 0.9 ppm SY + vitamin E 50 IU than control, 0.9 ppm SY + vitamin E 100 and 0.9 ppm SY + 150 IU in week 5. Haugh unit of the eggs during storage decreased significantly(P<0.05) from day 1 to day 11. However, Haugh units of the eggs from 0.9 ppm SY + vitamin E 150 IU treated groups did not decreased significantly until day 5. Yolk color was significantly (P<0.05) higher in 0.9 ppm SY + vitamin E 50 and 0.9 ppm SY + 100 IU than other treatment groups in week 1. Selenium concentrations of egg were significantly increased (P<0.05) in 0.9 ppm SY + vitamin E than control and vitamin E 100 IU groups. Lipid-soluble antioxidative capacity (ACL) in egg yolk was significantly (P<0.05) higher in supplemental combination of 0.9 ppm SY + vitamin E 150 IU when compared to those of other treatment groups.

Effects of packaging methods for maintaining the shelf-life and postharvest quality of Korean chive (Allium tuberosum Rotter) usually called buchu in Korea was studied during fall season. Buchu, which has high moisture content and active metabolism after harvest, is characterized by the greater changes in quality during storage and distribution. It is usually packaged in paper box during distribution in domestic channel in Korea where the marketability ends within few days of harvest. In order to maintain the commercial quality of buchu, we tried to use inner film with or without absorbent paper in commercial paper box packaging. The 'Greenbelt' cultivar of buchu was harvested in october and packaged in corrugated paper box (A), in corrugated paper box with micro-perforated high density polyethylene (HDPE) film as inner material (B), a layer of absorbent paper both at the bottom and top of buchu in corrugated paper box (C) and a combination of HDPE film as inner material along with a layer of absorbent paper both at the bottom and top of buchu in corrugated paper box (D), and stored at $5^{\circ}C$ for up to 21 days. Several quality parameters such as fresh weight loss, respiration rate, color, chlorophyll content and sensory qualities were monitored during storage. When buchu was packaged only in paper box, the appearance and quality deteriorated rapidly through decay development thereby sample became unmarketable within 12 days. On the other hand, buchu packaged with inner HDPE film maintained its quality, good visual appearance and exhibited a longer period of marketable life compared to the samples stored in other treatments. However, the use of absorbent paper did not have any significant effect in maintaining quality of buchu. The uses of inner HDPE film was effective in reducing weight loss that resulted better visual appearance of buchu. Results suggest that the use of inner HDPE film in bulk type corrugated paper box packaging and storing at $5^{\circ}C$ could be the optimum condition for commercial storage of buchu. Further investigation on other quality parameters and packaging methods would be useful in maintaining the quality aspects of buchu at postharvest stages.

A three-dimensional hydrodynamic model was applied to the Lake Euiam. The lake has three inflows, of which Gongji Stream has the smallest flow rate and poorest water. The dam-storage volume, watershed area, lake shape and discharge type of the Chuncheon Dam and the Soyang Dam are different. Therefore, it is difficult to analyze the water plume and mixing pattern due to the difference of the two dams regarding the amount of outflow and water temperature. In this study, we analyzed the effects of different characteristics on temperature and conductivity using the model appropriate for the Lake Euiam. We selected an integrated system supporting 3-D time varying modeling (GEMSS) to represent large temporal and spatial variations in hydrodynamics and transport of the Lake Euiam. The model represents the water temperature and hydrodynamics in the lake reasonably well. We examined residence time and spreading patterns of the incoming flows in the lake based on the results of the validated model. The results of the water temperature and conductivity distribution indicated that characteristics of upstream dams greatly influence Lake Euiam. In this study, the three-dimensional time variable water quality model successfully simulated the temporal and spatial variations of the hydrodynamics in the Lake Euiam. The model may be used for efficient water quality management.

This study was carried out to investigate the effect of antihypertensive peptides originating from marine proteins on ACE inhibitory activity and systolic blood pressure in spontaneously hypertensive rats (SHR). Sixteen male SHR (SHR/NCrj) weighing approximately 270 g were randomly divided into few experimental groups based on diet: C (control), A (anchovy), P (pollack) and M (mackerel). The final body weights of P and M groups were higher, than those of C and A groups, but difference was not significant. Average reference blood pressure (RBP) was 224 mmHg at 12 weeks old. Compared with RBP, final systolic blood pressure of the marine peptide oops after 28 days of feeding with anchovy, pollack and mackerel fractions by gavage was decreased by 9.0% (A), 10.2% (P) and 14.3% (M), respectively, but was not different in C. Especially, final blood pressure of M was lower by 32 mmHg than RBP. These results suggested that peptide originated from mackerel hydrolysate was considered to have an antihypertensive fraction as effective lowering of blood pressure in SHR.

This study was done to investigate how importantly midwives thought of Lamaze Method of Childbirth, how satisfactorily they performed their Lamaze Method of Childbirth and what inhibited their activities from being performed if not done satisfactorily. The subjects of this study were 76midwives at midwifery in Pusan, Deagu, Kyungnam and Kyungbok. Data were collected by using questionaire from Sep. 1 to Sep.30, 1991. The measurement tools was maded by the researcher based on Kim's scale for prenatal nursing activities. The statistical analysis was done with based statistical values likes frequencies, means, standard deviations and advanced methods such as Pearson's correlation coefficient, 1-test, F-test, F-test by using SPSS package program. The results of this study can be summarized as follows ; 1. The results of Investigating perception according to importance degree and performance degree of Lamaze Method of Childbring showed that midwives were slightly below both perception according to importance(2.17) and performance(2.16) of Lamaze Method of Childbirth 2. Inhibiting factors of Lamaze Method of Childbirth were abscence of husband(3.08), lack of teaching room(2.71), and lack of books or literature of Lamaze Method (2.58). 3. There appears to be a positive relation between perception according to importance degree and performance degree of Lamaze Method of Childbirth (r=0.69, P<0.01). There appears to be a negative relation between perception according to importance degree and inhibit factors of performance (r=-0.38, P<0.01). There appears to be a negative relation between performance and inhibit factors of performance (r=-0.22. P<0.01). 4. The item of highest perception defree in prenatal education is 1st, Consultation about sexual life (2.53), End, illustration of the importance of a bath and perinal cleanliness and Avoidance of excessive respiration method and also its comfortable application during uterine contractility(2.45). The item of lowest perception degree is about pregnant symptom sign and predicted date of birth (E.D.C.). On the other hand, The item of highest performance degree is education about nurtrition during pregnacy. 2nd, Illustration of the Importance of a bath and perineal cleanness(2.45). The lowest one is leaching the pregnant woman and her family about the role of husband and her family and also teaching the couple to learn exercise and respiration method (1.84). Though importance perception degree and performance degree is low. Midwives who wert subject in this research shoves that they perform general items concerning prenatal education well. 5. In the relationship between perception according to importance degree of Lamaze Method of Childbirth and the general characteristics of subjects, the differences in mean number of visiting pregnacies for 1 month. 6. In the relationship between performance degree of Lamaze Method of Childbirth and the general characteristics of subjects, the differences in age, marriage, and mean number of visiting pregnancies for 1 month. With the above information we see the importance of midwife prenatal care education and high correlation between performance degree and perception degree. When Lamaze prenatal education is well performed the number of pregnant woman who have follow-up, check-ups increase. Therefore in this research we can validity that there is a relation between Lamaze prenatal education and patient follow-up. This research showes in a situation where if one does not maximally perform a prenatal education there is a possibility that the popular use of midwife activities may encounter obstacles so the education to save new knowledge and training for prenatal education is needed as a function of Lamaze prenatal education, when a special Lamaze education is well performed for the pregnant woman, who follows-up at amidwife clinic. With the above conclusion we can suggest : 1. Continued research which minimized obstacles to Lamaze prenatal education is needed. 2. The official method of midwives is necessary.
