현업예보 관점에서 태풍의 온대저기압화 판단 과정에 대한 고찰
차은정,심재관,권혁조 한국지구과학회 2008 한국지구과학회지 Vol.29 No.7
온대저기압화는 중위도 기압계에 큰 영향을 주고 때로는 악기상의 원인이 되기도 한다. 그러나 온대저기압화에 대한 예보와 연구 양쪽 모두 많은 과제가 남아있다. 왜냐하면 태풍으로부터 변질된 온대저기압 자체의 모호한 형태 때문이다. 또한, 온대저기압화의 정의가 예보나 연구 양쪽 모두 만족시켜줄 만큼 정확하지도 않다. 따라서 기상청은 2007년에 “온대저기압화 현업매뉴얼”을 개발하여 온대저기압화의 일련의 과정과 구조 변화 진단에 사용하였다. 이 매뉴얼에서는 1단계 최대풍속과 해수면온도, 2단계 위성영상, 3단계 단열선도, 그리고 최종단계인 4단계에서 지상일기도를 분석하였다. 이 현업매뉴얼은 온대저기압화가 일어날 때 구조변화의 이해와 감시에 도움이 될 것이다. The extratropically transitioning cyclones have been shown to have a large effect on weather system in the midlatitues and cause sometimes the severe weather phenomena. However, both operational forecasting and research aspect of ET remain a significant challenge. Because it is difficult to distinguish ET stage due to obscure configuration of the cyclone itself. Furthermore, any definition of ET should not only be precise enough to satisfy the needs of the operational and research communities. Therefore, the "operational deterministic process for ET" was proposed and has been used to diagnose both structure and subsequent process of ET in 2007. In this study, it has been examined the maximum wind and SST in the 1st step, satellite image in the 2nd step, sounding in the 3rd step, surface weather chart analysis in the final step. This operational manual has allowed better monitoring and understanding of the changes in the structure as ET occurs.
The recent increase in the heavy rainfall events in August over the Korean Peninsula
차은정,이은정,전종갑 한국지구과학회 2007 韓國地球科學會誌 Vol.28 No.5
The characteristics of the rainfall events on the Korean peninsula have been investigated by means of regional1. According toour analysis, long-term annual rainfall anomalies show an increasing trend. This trend is pronounced in the month ofAugust, when both the amount of monthly rainfall and the frequency of extreme events increase significantly. Compositemaps on August during the 8 wet years reveal warm SST anomalies over the eastern Philippine Sea which are associatedwith enhanced convection and vertical motion and intensified positive SLP over central Eurasia during August. Therainfall pattern suggests that the most significant increase in moisture supply over the southern parts of China and KoreaPacific off the east coast of south China. The frequent generation of typhoons over the warm eastern Philippine Sea andtheir tracks appear to influence the extreme rainfall events in Korea during the month of August. The typhoons in Augustmainly passed the western coast of Korea, resulting in the frequent occurrence of extreme rainfall events in this region.Furthermore, anomalous cyclonic circulations over the eastern Philippine Sea also promoted the generation of tropicalcyclones. The position of pressure systems - positive SLP over Eurasia and negative SLP over the subtropical Pacific - inturn provided a pathway for typhoons. The moisture is then effectively transported further north toward Korea and east......... typhoon, heavy rainfall, August
근대화와 영국 아동문학 : 문학적 관점에서 아동문학 발전의 역사적 조건 재해석

The Victorian era was a golden age for children's literature. Changes in the social and historical conditions brought positive change to it. The French Revolution, the Industrial Revolution, modernization, individualism, family ideology, educational system, Romanticism, and the advent of child reader are very important points to children's literature. In the early stages of a printed literature, there are few or no books published specifically for children. Perhaps a few books are intended for broadly educational purposes, such as courtesy or behaviour books, In the situation children, as they learn to read, long for 'their' books which appeal to them. Gradually stories written specially for children being to appear and eventually demands for books to meet a variety of interests and special needs emerge. The economic and social transformation is closely connected with children's literature. It has important social and literary functions, and it offers social and literary meaning as well as enchantment. The printed works produced ostensibly to give children's spontaneous pleasure and not primarily not to teach them, nor solely to make them good. Through these views, we need to enlarge the children's literature as a social and historical products.

This study was attempted to soybean-paste by adding garlic, ginger, red-pepper in cooking pot stew. cooked and stored pot stew with five different levels of garlic, ginger, red-pepper (T: control, T_1: garlic 2%, T_2: ginger 1%, T_3: red-pepper 2%, T_4: garlic 2% + ginger 1%) was tested for sensory evaluation, pH, TBA value, microorganism and free amino acid change. 1) There were a slowly increase of TBA value during the first 5days storage in bowl. The inclusion of ginger extract at 1.0% level tended to lower TBA values. 2) No systematic increase of total microorganisms counts was detected during the storage periods for bowl. The inclusions of ginger extract did not pose any microbiological safety problem. 3) Sensory evaluation conducted by fifteen graduate students as panelists showed that there were significant differences of taste, flavour, overall acceptability in five samples, especially the notablest preferences in T_1 sample. 4) The main ingredients of heated free amino acid were glutamic acid, aspartic acid, leucine, glycine, alanine. After boiling 20 minutes once and 10 minutes twice, the level of these was highest, after boiling three times more has reduced entirely.
