The purpose of this study is to identity the representative flower patterns in the Joseon Dynasty and investigate their chronological transitions. In the early Joseon Dynasty (i.e. 16th century), lotus patterns were very popular. Often lotus patterns were twisted around by ivy-leaves or decorated with treasures pattern in the margin. In the mid Joseon Dynasty (i.e. from 17th to mid 18th century), however, lotus patterns evolved from the typical lotus and ivy pattern and diversified into four types. In the 19th century, lotus pattern almost disappeared from the textiles of everyday dresses and were only found in the textiles of formal dresses or in special cases as in the cover pages of Buddhist scriptures. Poeny patterns was rarely used in textiles of 16th century, presumably because of the huge popularity of the lotus pattern. However, suddenly in the 17th century, Poeny patterns appeared quite frequently. There were 3 types of Poeny patterns. Poeny patterns became more popular over the years and it finally became a primary motive in textiles patterns for 100 years starting in the late 19th century. There were two types of Poeny patterns : one was realistic and true to life even in sizes, the other was more symbolic. Textile patterns combining four kinds of flowers started to appear from the late Koryo Dynasty but Flower patterns representing four seasons with distinct shapes appeared only in the 17th century. They could be categorized into three types. In the late 18th century, Flower patterns representing four seasons no longer appears in textile patterns, presumably due to a new preference for lucky omen over natural motives.

Cha, Jong Whan (Dept. of Biology, Graduate School, Dong Kuk Univ.) The changes of chemical properties of forest soils in dry and wet seasons. Kor. Jour. Bot. VII(2): 1-8, 1964. Soil selected for the present investigation was collected from a mountain of the Forestry Experiment Station of the vicinity of Seoul. The forest communities studied were three forest and a unplanted soils. The soil samples were obtained from each forest type during dry and wet seasons. And these samples were collected from four horizons of all communities respectively. It was showed that exchangeable hydrogen was increased by rainfall, and total exchangeable base decreased in the same way. The content of nitrogen is washed away by rainfall, especially ammonium nitrogen was highly significant between dry and wet season. On the contrary, organic matter and available phosphorus were of no significant difference between dry and wet seasons. The values of pH appeared a different response in dry and wet seasons according to the plant communities. The needle-leaved forest soils showed more acidity than the broad-leaved forest soils, and the least acidity in open places. All nutrients in soil studied gradually decreased down the profiles. According to statistical analyses of the soil components among all soil horizons, total exchangeable bases in wet season indicated only significant at 1%. Exchangeable hydrogen and organic matter of the soil in dry season was particularly very low with increased depth in the profile. The fertility level of most forested soils selected for the present investigation is low according to chemical tests for available nutrient elements.

Direct measurements of four radiative components at air-sea boundary layer were conducted in the southern Yellow Sea during three cruises (seasons) in 2007. Simultaneous observations of meteorological (cloud cover, air temperature and humidity) and oceanographic (sea surface temperature) parameters were carried out. Observational results of radiative fluxes and meteorological and oceanographic parameters are presented. Mean diurnal cycles of four radiative components, net radiation, and sea surface albedo are calculated to achieve averages in different seasons. Net radiative fluxes in three seasons (winter, spring, autumn) are 8, 146, $60\;W/m^2$, respectively. Comparisons between the observed radiative fluxes and those estimated with formulas are taken.

Fabrics dyed with artemisia extract have quite natural and elegant tones of color. This study purposed to find the best one for dyeing among artemisia collected in the four seasons in order to develop a more efficient method of dyeing with artemisia. As for the method of research, the researcher dyed wool fabric and silk fabric with artemisia, and measured dyeability according to the number of repeats of dyeing, coloration by post-mordant, color fastness to washing, color fastness to dry cleaning and color fastness to light. The results are as follows. 1. In dyeing with artemisia, dyeability was improved as the number of repeat of dying increased, and it was higher in wool fabric than in silk fabric. 2. Among artemisia collected in the four seasons, autumn artemisia had dyeability much inferior to that of artemisia from the other seasons, and winter artemisia had the best dyeability. 3. According to the result of treating fabric with post-mordant, the dyeability was improved significantly, and coloration was most remarkable when copper and iron mordant were used. 4. The color fastness to washing and color fastness to dry cleaning of fabric mordanted with artemisia were as high as grade 4-5 and grade 5 respectively. The color fastness to light was highest in winter artemisia as grade 4.

To understand the function of nursery grounds, the seasonal variation of ichthyoplankton was investigated in the East Sea, off Dokdo, from September 2009 to May 2010. The dominant species was Engraulis japonicus (92.7%), which occurred in May and September. The next abundant species was Maurolicus japonicus (5.7%), found in all four seasons. Several rare warm-water species were found in September and November, when the species diversity was higher than in the other two seasons. Several fish species used Dokdo as a nursery ground for a restricted season, while M. japonicus used it in all four seasons.

The purpose of this study was to determine the effect of cows parity and calving seasons on the subsequent reproductive performance of the herd of Korean native cows raised under the same condition. With the parity of the cows ranged 1 to 4 (mean: 1.9), significant associations were found between parity and calving interval (p<0.05). Calving interval of the primiparous cows group was 395.0 ${\pm}$ 16.5 days, which was the longest calving interval among the four groups. On the other hand, calving interval of the second parity group was 333.7 ${\pm}$ 3.6 days. The primiparous cows had tendencies that long interval from calving to conception and small number of service per conception relatively when compared with the multiparous cows. In the case of calving season, the interval from calving to first service was short in summer and winter relatively. The interval from calving to conception in summer was the shortest in four seasons. The number of service per conception was larger in spring and winter and smaller in summer and autumn. Calving in spring showed delayed reproductive performance and calving in summer showed desirable reproductive performance.

In this paper, I studied about historical seasonal subdivision system and a theory of traditional monthly order, which was used for so long from Koryo dynasty to the late of Choseon dynasty in Korean histoy. Especially, I took note of the fact that there used the table of solar terms and meteorological observation what we called the table of Kihoo-pyo in the historical Sunmyung-calendar and the Soosi-calendar during the Koryo dynasty. This table of Kihoo was developed for explaining meteorological change during a year at that time. Here are largely four elements related meteorological nature : the first is the list of 24 solar terms, and the second is 12 monthly seasonal terms and 12 monthly central terms, the third is about four right hexagon based I-ching, the fourth is 72 meteorological observations called 72-hoo. Among them, the 72-hoo system is important to know how premodern people observed natural materials including animals and plants, weather, climate about meteorological phenomena according to the seasonal change or solar terms' change during a year. I argued in this article to need developing modern new table of Kihoo system like that, in order to show common people to recognize annual meteorological change more easy and clear. I also argued to need a distinct definition of meteorological seasons from a view point of modern meteorology.

The human body and nature respond to each other. The change of nature influences to directly human body. One of the change is the weather change. and there is order in the change. The order is twelve months. To explain the weather change of the cold, hot. dry and wet. we can use Four seasons, The twenty-four seasons, or The twelve month. To explain the five elements of the chinese cosmogony, The four season is useful, and the change of weather, the twenty-four seasons is good. But, the viscera is explained by the ten celestial stems and the twelve horary sings. Thus the twelve horary sings is most useful to explain, because one year is composed by twelve months. The twelve season and fancy of the ten celestial stems is explained fully by Diao-hou-yong-shen. Diao-hou-yong-shen is expressed by the zodiac signs, and explained by the disposition of the zodiac sings. In addition to the oriental medical science is also explained and expressed by the zodiac signs. Therefore, I think that the change of viscera, according to weather, is based on the Diao-hou-yong-shen, and I get some results. In the acting of viscera, there are some relationship between organs. The relationship is not influenced directly by the weather of four seasons, unless there are some special details. If the energy of the month, which rules one specific organ, is weak, doctor should fill up the organ. If not, the organ tends to get sick. According to the full or weak of the five elements which is under the month, the useless or harmful elements should be taken off, and useful and needful elements should be serviced. The balance between cold, hot, dry and wet should be maintained. However, the fancy of the viscera is very different. So, doctor should be careful to maintain balance. The full and weak between Yin and Yang should be considered when doctor think about cold and hot in the month.
