This study was carried out to investigate the incorporation effect of green manure crops (GMC) such as the hairy vetch on improvement of soil environment in reclaimed land during sorghum${\times}$sudangrass hybrid (SSH) cultivation over the past three years from 2009 to 2011. Plots consisted of conventional fertilization (CF) and incorporation of GMC were divided by rates of additional nitrogen fertilizer ($100kg\;ha^{-1}$) and decreased percentage of 30 50 70 100 fertilization in addition to non nitrogen fertilization (NNF). Soil physico-chemical properties, growth and yield potential were examined. The results were as follows. The testing soil was showed strong alkaline saline soil with low organic matter contents and less available phosphate while exchangeable sodium and magnesium were higher. Soil salinity was increased during cultivation of summer crop. However, SSH was not affected by salt content. The fresh weight of GMC at incorporation time was $18,345kg\;ha^{-1}$. Content of total nitrogen at incorporation time was 3.09% and the C/N ratio was 12.8. Fresh and dry matter yield of SSH were higher in the order of 30%, CF, N50%, N70%d, N100%, and NNF. Fresh and dry matter yield of SSH increased in the order of CF ($55,050kg\;ha^{-1}$, $16,250kg\;ha^{-1}$), N contents from 30% to 9%. Soil physical properties, such as bulk density were decrease with incoporation of GMC, while porosity was increased. Soil chemical properties, such as pH was decreased while content of exchangeable calcium, available phosphate, and organic matter were increased. Also contents of exchangeable sodium and potassium were decreased with incorporation of GMC than those before experiment. Thus, we assumed that incorporation of hairy vetch was more effective that can lead to reduce chemical nitrogen fertilizer and to improve soil environment in cultivating SSH on Saemangeum reclaimed land.

The Precambrian quartzite and calc-schist layers experienced multi-1310ing events are distributed along the two kinds of U-shaped 1310 (Fold I and II) with $N10^{\circ}E-directed$ fo1d axis in Wollong-myeon, Gwangtan-myeon, Jori-myeon of Paju city, the northeastern part of Gyeonggido. Occurrence of 10 layers of quartzite and 4 layers of calc-schist is not clear whether quartzite and schist layers were deposited sequentially each other or one to two layers of quartzite and schist were distributed repeatedly by isoclinal folding and thrusting, because of lack of sedimentary structures. In this paper, we tried to clarify the correlative relationship among the quartzite beds which are distributed along the U-shaped folds using geochemical tools such as rare earth element (REE) patterns and Nd isotope ratio. Quartzites have characteristics of LREE-flattened, HREE- slightly depleted patterns. They also show Ce negative anomaly whereas there are no Eu anomalies. As a result, quartzite beds occurred along the bilateral sides of fold axis show very similar REE patterns from outer side to inner side of 1314. The Nd model age of quartzite layers shows a trend that the inner part of fold is younger than the outer part of it. Such geochemical characteristics suggest that bilateral quartzite beds occurred along the fold axis were derived from the cogenetic source materials. The REE patterns and trace element geochemistry of mica schist intercalated within quartzite indicate that the quartzite and mica schist may be derived from different source materials. Our results suggest that REE and Nd isotope geochemistries may be very useful in clarifying the relationship of sedimentary deposits which do not show stratigraphical and structural connections in the field.

Objective: This study was to evaluate the health-related quality of life (HRQoL) among patients with diabetes in Korea and to compare them with the HRQoL of individuals without diabetes history. Methods: The study subjects were 17,655 adults aged over 19 who participated in the 5th Korea National Health and Nutrition Examination Survey (2010-2012). The EuroQoL-5Dimension was used to evaluate HRQoL. Chi-square test, t-test, ANOVA and multiple regression analysis were performed to test the difference of HRQoL in diabetic subjects and controls. Results: The mobility dimension was the highest reported problem: 36.4% for diabetic subjects. The proportion of any reported problem was significantly high among diabetic subjects compared with two controls in terms of mobility [reference group: diabetic subjects, chronic controls: adjusted odds ratio (aOR)=0.77, 95% confidence interval (95% CI)=0.66-0.91, healthy controls: aOR=0.61, 95% CI=0.50-0.75], self-care [reference group: diabetic subjects, chronic controls: aOR=0.68, 95% CI=0.55-0.83, healthy controls: OR=0.69, 95% CI=0.51-0.94]. and usual activities [reference group: diabetic subjects, chronic controls: aOR=0.85, 95% CI=0.72-0.99, healthy controls: OR=0.79, 95% CI=0.62-0.98]. Also, EQ-5D index were significantly low in subjects with diabetes compared to two controls. Conclusions: Subjects with diabetes had a significantly lower HRQoL compared with two controls. To improve the quality of life of diabetics, it is necessary to study various variables related to the quality of life, and develop and manage various health programs or welfare policies reflecting socio-demographic characteristics and health related features that affect the quality of life.

This study was conducted to characterize comparatively the accumulative patterns of protein and oil, temporal changes in electrophoretic components of proteins during seed development and maturation for the soybean varieties with high, medium and low protein contents. 1. The dry matter of the developing seed increases slowly for the first 22 days after flowering, followed by rapid linear increase for 20 to 30 days and further slow increase for 5 to 15 days attaining its maximum. During the period 12 to 27 days after flowering the protein content of seed increases rapidly while oil content increases rapidly. Following this period of rapid changes, there was period of slow increase until 40 to 47 days after flowering and no seizable further change in the content of both protein and oil. 2. The high protein variety, Saikai # 20, was characterized by shorter period and lower rate of decrease in protein content during the early period, followed by longer period and higher rate of increase in protein content, with earlier stop of oil accumlation during the seed development. 3. The low protein and high oil variety, Shelby, was characterized by longer period of decrease in protein content and shorter period of increase in protein content in contrast to the longer period of slow oil increase during seed development. 4. The temporal pattern of protein component accumulation during seed development was distinctly different among varieties differing in protein content. The time of distinct appearance of all the protein components identifiable in the matured seeds was in accordance with the end of d crease in the protein content of seed. A component having Rm of 0.03 which was absent in the matured seeds was identifiable during the first 17 days after flowering. 5. The high protein variety, Saikai # 20, had much higher compositioral ratio of the component a from the early days of seed development and it continued to increase until 47 days after flowering, while the increase in the composition of the component a stopped as early as 27 days after flowering in the other lower protein varieties. 6. The composition of the component b increased during the period from 17 to 42 days after flowering in all the varieties tested, but the rate of increase during the period was lowest in the high protein variety, Saikai # 20.

The concentration of terpene (18 species) was measured from spring to fall in ambient air and essential oil at three different forests located in Jeollanamdo province. Sampling was conducted at 4-hour-interval a day of each season. In the ambient air, ${\alpha}$-pinene, ${\beta}$-pinene and 2-carene were the most abundant compounds throughout the sampling periods and areas. The highest three-season average concentration of total terpene was 2,597 pptv at Jeamsan(Mt.) in Boseong which was predominantly populated by Pinaceae. The seasonal averages were observed to peak during spring with their max at Palyeongsan(Mt.) in Goheung and Jeamsan(Mt.) in Boseong, and during fall at Woodland in Jangheung. Most of terpenes had diurnal variations with higher concentrations during the daytime, and lower during the nighttime. However in essential oil, the highest annual average concentration of total terpene was $798{\mu}g/dry-g$ at Goheung which was predominantly populated by Chamaecyparis obtusa. Also, the component proportion ratio showed different distribution between ambient air and essential oil. From the results of this study, we suggest that Chamaecyparis obtusa species is more useful, and younger tree is more economical than older one, and spring is the best season for lumbering in order to use essential oil.

The main focus of this study was set to help college students in Kangwon province to improve and correct dietary habits and to maintain healthy life. The nutritional status and food preference of college students were examined from May to July, 1999. The collection of the research data has been made on the basis of questionnaries for 184 college students residing in Kangwon province. Statistical analysis of the data was performed using SAS package program for descriptive frequency and statistical significance. The meal skipping ratio of the subjects were 2% and for the reasons of meal skipping 45% responded "lack of time". As for main dishes, cooked rice turned out to be the most preferred by the subjects and the second and third favored by female students were bread and noodle respectively. Most preferred side-dishes were meat soup, kimchi, laver Kui,squid Bockeum, fried squid, beef Chon, squid Chorim, soy Namul, Dubuk Changachi and squid Muchim. Less preferred side-dishes include radish soup, white kimchi, mugwort fry, liver Bockeum, liver sheon and egg plant Kui. No one-plate food was disliked by the subjects. Male liked Manndukuk and female liked cuttle fish rice. The intakes of nutrient except for energy, iron and calcium for female students were the same or above the Recommended Dietary Allowances (RDA) for Koreans.

Purpose : The objective of this study was to assess ventricular function by tissue Doppler imaging (TDI) in children with congenital heart disease (CHD) who have been undergoing open heart surgery (OHS) using cardiopulmonary bypass. We tried to compare the parameters of tissue Doppler imaging before and after OHS in patients with congenital heart disease. Methods : This study was conducted on 32 patients with CHD after OHS from January 2005 to December 2005 at Kyungpook National University hospital. Patients who underwent 2-D echocardiography before and after their OHS. All patients were divided into three groups, left ventricular volume overloading group (group 1), and right ventricular volume overloading group (group 2), and right ventricular pressure overloading group (group 3). The TDIs were examined before and 1 to 3 months after OHS. Peak early diastolic (E), and peak late diastolic (A) velocity of transmitral flow were measured by pulsed wave Doppler examination. Peak systolic (Sm), peak early diastolic (Em), and peak late diastolic (Am) velocity in apical 4-chamber and 2-chamber views were measured by TDI. The author calculated E/Em ratio. Results : The patients were 14 boys and 18 girls and the average age of patients was 2 years and 3 months. The congenital heart diseases which have to get OHS were ventricular septal defect (13 cases), atrial septal defect (7), atrioventricular septal defect (3), isolated pulmonary stenosis (2) and tetralogy of Fallot (7). There were significant decrease of Sm, Em, Am measured on tricuspid annulus and E/Em measured on mitral annulus in apical 4 chamber view (P<0.05). Conclusion : This study showed significant decrease of Sm, Em, Am measured on tricuspid annulus and E/Em measured on mitral annulus in apical 4 chamber view after OHS. These changes might be due to the effects of cardiopulmonary bypass in OHS and/or hemodynamic changes after correction of congenital heart disease. To clarify these changes, further study on more patients is needed.

Objective of this research was to investigate the influence of $NH_4^+$ and $NO_3^-$ ratios in liquid feeding on the growth of snapdragon 'Potomac Red' and changes in medium chemical properties. The seeds were sown into 200 plug trays and fertigated once a week with nutrient solution containing various ratios of $NH_4^+$ and $NO_3^-$ such as 0 : 100, 27 : 73, 50 : 50, 73 : 27, and 100 : 0. The total N concentrations were adjusted to 50, 100 and $150\;mg{\cdot}L^{-1}$ in plug stages of 2, 3, and 4, respectively. Determination of seedling growth and analysis of plant tissue and root medum were conducted at 56 days after sowing. The treatment of 27 : 73 ($NH_4^+:NO_3^-$) had the greatest plant height, fresh weight, and dry weight. The N and P contents in 27 : 73 ($NH_4^+:NO_3^-$) treatment based on the above ground plant tissues were 2.39 and 0.39%, respectively, which were the greatest among treatments. The elevation of $NH_4^+$ ratio in fertigation solution decreased tissue Ca and Mg contents, but that did not influence tissue K content. The variations in $NH_4^+:NO_3^-$ ratios impacted the soil solution pH and the difference among treatments had been severe since three weeks after sowing. Elevation of $NH_4^+$ ratios in fertigation solution increased electrical conductivity and concentrations of K, Ca, and Mg in soil solution of root medum. The $NH_4^+$ and $NO_3^-$ concentrations in the soil solution were high in weeks 2, 3, and 4, then decreased gradually as the biomass of seedlings increased. Medium P concentration decreased gradually as seedlings grew, but statistical differences were not observed among treatments.

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.
