The purpose of this study is to analyze the evolutionary process of Ddeulzip. The subject of this study is a clan family of Andong Kwon in Andong Area. Ddeulzip's evolutionary process of the construction and management is divided into largely three periods in Josun Dynasty. The establishment and changing process of Ddeulzip for Andong Kwon's family are analyzed according to three periods called the early(15~16C), mid(17~18C) and late(19~20C). The characteristics of the early and mid period are that they created their own ancestral building form of Ddeulzip. Those of the late period are in their strong will to make similar scale of Ddeulzip. And during the late period, although the construction of new Ddeulzip was started in the early stage, no more formation of Ddeulzip was made as it approached toward the late stage. And most important point is similar constructional space(gan) of first time. The residential Ddeulzip of Andong Kwon's family created at the 19C can be regarded as an representative example of large space that shows a typical form of housing by noble residents at the time.

To understand day-to-day fluctuations in soil moisture content in Seoul, I simulated daily soil moisture content from 1908 to 2009 using long-term climatic precipitation and temperature data collected at the Surface Synoptic Meteorological Station in Seoul for the last 98 years with a hydrological simulation model, BROOK. The output data set from the BROOK model allowed me to examine day-to-day fluctuations and the severity and duration of droughts in the Seoul area. Although the soil moisture content is highly dependent on the occurrence of precipitation, the pattern of changes in daily soil moisture content was clearly quite different from that of precipitation. Generally, there were several phases in the dynamics of daily soil moisture content. The period from mid-May to late June can be categorized as the initial period of decreasing soil moisture content. With the initiation of the monsoon season in late June, soil moisture content sharply increases until mid-July. From the termination of the rainy season in mid-July, daily soil moisture content decreases again. Highly stochastic events of typhoons from late June to October bring large amount of rain to the Korean peninsula, culminating in late August, and increase the soil moisture content again from late August to early September. From early September until early October, another sharp decrease in soil moisture content was observed. The period from early October to mid-May of the next year can be categorized as a recharging period when soil moisture content shows an increasing trend. It is interesting to note that no statistically significant increase in mean annual soil moisture content in Seoul, Korea was observed over the last 98 years. By simulating daily soil moisture content, I was also able to reconstruct drought phenomena to understand the severity and duration of droughts in Seoul area. During the period from 1908 to 2009, droughts in the years 1913, 1979, 1939, and 2006 were categorized as 'severe' and those in 1988 and 1982 were categorized as 'extreme'. This information provides ecologists with further potential to interpret natural phenomenon, including tree growth and the decline of tree species in Korea.

phenological study on the oviposition, emergence, and flight activity of the African mole cricket adult has been made to obtain basic information for management of pest populations in ginseng fields. The flight activity, as monitored by the blarklight trap, seemed to be initiated depending on the sunset time and lasted about 2-2.5 hours. The trap data (1984-1988) showed that the adult flight of the species occurred twice a year, from early May to late June(Spring flight) and from late August to mid October(Fall flight) during which usually more crickets were trapped than during the former period. The number of females trapped was greater than that of males regardless to the flight period, i.e., females comprised 72.2%, 83.9%, and 73.3% of the total catches in 1984, 1985, and 1986, respectively. Adults emerged from late August to mid October and laid eggs from mid May to mid July the next year, indicating that the spring and fall flights correspond to the oviposition and emergence period, respectively.

The transplanting period limit considering the rice yield in the Dague region, the inland plains of Gyeongsangbuk-do, was estimated to be July 15^th for early and mid-maturing rice and July 5^th for mid-late maturing rice. However, as the transplanting time was delayed, the characteristics of rice starch changed significantly. In the case of early and mid-maturing rice varieties, the starch granule size increased as the transplanting time was delayed; the opposite tendency was observed for mid-late maturing varieties. In all mature rice types, the late transplanting resulted in a longer pasting time and a higher pasting temperature. In addition, the peak viscosity, breakdown, and gelatinization temperature were significantly lowered, the relative crystallinity degree decreased, and the setback was significantly increased. In the case of Ilpum, a mid-late maturing rice variety, the distribution of amylopectin short chains tended to increase when rice was transplanted on June 30^th.

Those of the mid period are in their strong will not only to preserve their on ancesteral housing but also to make additional construction of Ddeulzip. And during the late period, although the construction of new Ddeulzip was started in the early stage, no more formation of Ddeulzip was made as it approached toward the late stage. And most important point is smaller construction space (gan) dan first time. The residential Ddeulzip of Euisung Kim's family created at the start of Chosun Dynasty can be regarded as an representative example that shows a typical form of housing by noble residents at the time.

Effects of IPTG induction on cell growth and production of ${\beta}$-galactosidase-preS2 fusion protein (${\beta}$gal-preS2) were studied in a defined medium using a recombinant Escherichia coli JM109/pCMHB30. IPTG was added (0.2 mM) to induce the cloned-gene expression in the early-, mid-, and late-log growth phases. The most serious decreases in growth rate and plasmid stability were observed for the induction in the early-log growth phase. The expression level of ${\beta}$gal-preS2 attained by the induction in the mid-log phase was about 0.51 mg fusion protein/mg total cellular protein, which was 2- and 5-fold improvement over the levels obtained with the inductions in the early- and late-log phases. Formation of acidic byproducts including acetate and pyruvate showed different profiles during the fermentation period for each cases of induction; pyruvate was the major byproduct for the induction in the early-log phase while acetate production became more significant for the cases of inductions in the mid- and late-log phases.

This report studied the individual number, their favorite habitat, and change pattern of family and group number in Cheolwon Basin, starting in the early Oct. 2004 until late March. 2005 to investigate the ecological features of the Red-crowned Crane and the White-naped Crane. The Cranes arrived Cheolwon Basin in mid-October until next mid-March, and passed the winter in mid-November until next late-February The most visiting number amounted to 550 individuals and, that period was the most frosting mid-January to mid-February. The White-naped Crane visited Cheolwon Basin in autumn, the early winter and spring. Approximately, the wintering-number is 550 individuals, also, the mid-March was the peak-period of arrival and, the number amounted to 2,162 individuals. The cranes chose the farming area around mountains as their wintering habitat and were less likely to choose the farming area around lake as habitat. The Red-crowned Crane and the White-naped Crane showed the different periodical pattern in familial and group numbers. In case of the crane, the familial pattern was stable, but varied in grouping number, and this pattern was similar to the variation of overall individual number. And, also, the most grouping number was shown in the most freezing period of wintering period. The White-naped Crane showed the similar pattern of the Red-crowned Crane that is, stable family number and varying group number, this pattern affected the total number of entire individuals. Grouping number increased in migration period. Parasite infection rate is G japonensis 35.0%, G vipio 38.7%.

This article dealt with the formation and dissolution of tautological structure in the Frank Stella's work from 1959 to 1980 years by the analysis of signifier. A characteristic of Stella's work change is that it has the gradual progress which condensed into three periods -1) the formation and fixation period of tautological structure 2) the relaxation period of tautological structure and 3) the dissolution period of tautological structure. In other words, the early works of stella in the early 1960s has the structure which minimize differences in one hand, and maximize strictness, clearness, and identity on the other hand However, the stella's work from mid 1960s to mid 1970s extend differences gradually, while keeping a characteristic of prior work. And the stella's work after late 1970s has the decentered disintegration, namely anti-tautological structure which maximize differences. 'The formation and dissolution of tautological structure' in the Stella's work could be understood in relation to the fact that the Greenberg's modernist canon has loss the power gradually after late 1960s. That is to say, the dissolution of tautological structure in the late stella's work could be interpreted as the inevitable product which is produced in the searching for a new canon of painting. However, on the other hand, the structural change of stella's work in the late 20th Century is also understood in relation to the broader context, the social, and cultural context. Here, it is interpreted as the one of typical example which reflect a social and cultural convulsion designated as a 'Coming of Postmodernism'. In short, the late Stella's work which emphasize differences and unclearness, while diverging from early Stella's work which stress identity and rationality could be interpreted that it has the homology with the change of ways of thinking in the late 20th century Society.

The purpose of this study is to analyze the changing process in the Ddeulzip of Jinsung Lee clan family. The subject of this study is clan family of Jinsung Lee in Andong Cultural Area. The period of Chosun Dynasty is divided into largely three parts. The establishment process for Jinsung Lee's family is analyzed during early (15~16C) and mid(17~18C) periods, and changing process is analyzed during mid(19~20C) and late periods. The characteristics of early Chosun Ddeulzip is that it made a foundation to construct a Ddeulzip form. Those of mid Chosun period is in their strong will to preserve their ancestral house which is well manifested through the restoration of Taegye's ancestral house. During the late Chosun period, many of the different styles of Ddeulzip were constructed due to the stable environment of both political and economical status. The residential house of Jinsung Lee family that were centered in Yean area include diverse forms for both high and middle class social status. Jinsung Lee family's Ddeulzip is thus considered to bring about the firm foundation as a clan family representing the Andong cultural area through the development of Ddeulzip.

Mungbean is used for not only seed but sprout, so, consumption of mungbean has been on the rise in Korea. Life cycle of mungbean tends to be short among Legume. For that reason, Mungbean can be harvested for various cropping system and season per regions and farmers regardless of sowing date and harvesting date. So, Prior research is needed about growth characters and life cycle of mungbean per sowing period. Mungebean cultivar 'Dahyun' and 'Sanpo' supplied by Korea Agriculture Technology Promotion Agency(KOAT) is cultivated in wagner pot. Sowing period is proper time of seeding in Jeollanam-do and Gyeongsangnam-do that is major cultivation region of mungbean in korea from early May to mid July every 2 weeks. Length at maturity stage tends to increase from early May(sowing date: 4^th May) to early July(sowing date: 5^th July), but after that, It tends to decrease from mid July(sowing date: 19^th July). Number of branches and nods shows a similar trend. Length of pod has no tendency and no difference per sowing date. Number of pod per plants has also no tendency per sowing date. Test plots sowing in late May has the most number of pods.(Sanpo 22.9pods, Dahyun 16.8) Number of seeds per pod tends to increase to late May and Test plots sowing in mid July has the most number of seed per pod. In case of sowing at early May, Days of emergence is 7d. its summation of temperature is 132.2℃. After that, it tends to decrease to mid June. After mid June, Days of emergence is fixed to 3d. Average temperature growing up in this season, Summation of temperature from sowing to emergence takes the lowest point in test plots sowing in mid June.(Sanpo 88.6℃, Dahyun 88.6) Days of flowering tends to fasten from early May to mid July. Two cultivar shows same level. Days of maturity tends to fasten to mid June, after that tends to slow. In case that many research results about growth characters and life cycle mungbean per sowing period are drawn, it is expected that it result in increase of cultivation area and income of farmer.
