  • The experiments were carried out to investigate the effect of humidity on the cocoon quality, and 4, 000 lots of cocoon pruduced fot five years in Chin yang, Ha dong, Keo chang, San chung of Kyeong nam, and Sun san, Sang ju, Young poong, An dong of Kyeong buk were analyzed. The results were summarized as follows ; 1. The reelability ration, the bave length, and raw silk ration were decreased with increasing the humidity in mounting time, and it was remarkably observed when the relative humidity was over 80%. 2. With increasing the reelability ration, the bave length, and raw silk ration were increased, and the longer the bave lenger the bave length was the higher raw silk ration obtained. 3. The average reelability ration for five years in autumn-rearing period was higher than that in spring-rearing period, but the bave length and raw silk ratio was on the contrary from the above. 4. The reelability ration of cocoon produced in the mountainous area was higher than that in the field area but the shorter the bave length, the raw silk ration had no significant difference between those.

  • The physicochemical quality characteristics of the domestic and imported commercial dried persimmons were investigated. The moisture content of dried persimmon was approximately 22.78~61.64%, while the moisture contents of the Chinese dried persimmon were 22.78 and 28.20%, respectively, and were lower than the domestic dried persimmon. The pH of the Chinese dried persimmon was 5.09~5.99, while the pH of the Haman dried persimmon has the highest value (pH 5.99). The Brix was approximately $25.07{\sim}42.93^{\circ}Brix$ and weight of dried persimmons were 29.77~77.95 g, while the weight of Yeongdong dried persimmon has the lowest (29.77 g), and the weight of the Sancheong dried persimmon has the highest value. The L values were 18.27~66.20. The a values were -1.26~10.70 and a value of the Sancheong dried persimmon was 10.70, which was the highest. The b values were 2.81~25.25, wherein the b value of the Cheongdo semi-dried persimmon and Sancheong dried persimmon were25.25 and 21.98, respectively, and were higher than others. The appearance score of the sensory characteristics were the highest in Cheongdo semi-dried persimmon, while the appearance score of Wanju black persimmon was 1.39, which was the lowest. The overall acceptability of the Chinese dred persimmons (No.2) was the highest, while that of the Yeongdong, Hadong and Sangju dried persimmons have higher values than the other dried persimmons. The sulfur dioxide content of the 9 kinds of commercial dried persimmon was lower than 10 mg/kg, but not detected.

  • Field monitoring was performed to evaluate the soil chemical properties of 31 sweet persimmon orchard soil samples every two months from April to October in 2008 at Gyeongnam Province. Soil chemical properties such as pH, organic matter, available phosphate, exchangeable potassium, exchangeable calcium, exchangeable magnesium, exchangeable sodium, ammonium nitrogen, and nitrate nitrogen were analyzed. The soil chemical properties of both top soil, and subsoil showed that soil pH was significantly increased whereas ammonium nitrogen, and nitrate nitrogen were significantly decreased. The insufficient levels of nutrients in top soil, and subsoil were higher in 69.4%, and 84.7% for pH, 63.7%, and 84.7% for organic matter compared to optimum range. Meanwhile, the excessive levels of available phosphate showed 70.2% in top soil, and 46.8% in subsoil compared to optimum range. The experimental results showed that the optimum fertilization based on soil testing was the most important thing in soil nutrients management for sweet persimmon.

  • Precambrian metamorphic rocks of southwest Sobaeksan massif consist of mainly granitic gneiss, porphyroblastic gneiss and quartzofeldspathic gneiss. The orthopyroxene-bearing rocks(charnockites) are found in the west of Hadong-Sancheong anorthosite complex. The charnockites are 3km wide, 12km long and divided into massive and foliated types based on their texture. The compositions of charnockites are comparable to granodiorite to adamellite and subalkaline. Variations in major and trace elemental abundances show typical magmatic differentiation trends. The geochemical data plotted on tectonic discrimination diagrams reveal that these charnockites were formed in the active tectonic environment. The massive and folidated charnockites are mainly composed of plagioclase, orthopyroxene, microcline, quartz and disseminated garnet. Camels generally show characteristic zonal textures with decreasing $X_{alm}$(0.74~0.83), $X_{Py}$ (0.07~0.12) and $X_{Mg}$ (0.12~0.08) and increasing $X_{grs}$(0.03~0.15) from core to rim. Metamorphic temperature and pressure of the charnockites estimated from orthopyroxene-garnet-plagioclase-quartz assemblages show wide range of variation of $600~900^{\circ}C$ and 2.5~7.5 kbar respectively. The results of P-T estimates indicate an anticlockwise P-T evolution path.

  • Overwintering ecology of the peach pyralid moth, Dichocrosis punctiferalis Guenee (Lepidoptera: Pyralidae) was studied in laboratory and in a chestnut orchard in 2001/2002 winter and 2003 spring. All twenty-four female and fourteen male moths were fruit-feeding type which were emerged from the larvae collected at the same chestnut orchard in 2003 winter. Periodical thermal treatment of overwintering larvae at $25^{\circ}C$ revealed that diapause termination of the larval population started from the end of January and was completed until April 20 in southern region of Korea. Pupation of diapause-terminated larvae started from early May and reached to $100\%$ at June 3 in chestnut orchard. Days to pupation of female larvae after diapause termination were 12.5, 8.9, and 7.5 at $20^{\circ}C,\;25^{\circ}C$, and $30^{\circ}C$, respectively. Those of male larvae were similar to those of females. Pupal periods of female were 14.7, 11.8, and 9.0 days at the three temperatures. Moths of the overwintered generation emerged from May 20 to June 28, and reached to $50\%$ emergence on June 8 to 9 under emergence cage. Attraction of the male moths of overwintered generation to sex pheromone traps showed that the date of $50\%$ catches to the traps were June 17, when data from 3 southern regions of Korea were pooled.

  • Semi-quantitative analysis of $less-than-2{\mu}m$ clay minerals in thirty-nine superficial sediments from the Chinju Bay, southern coast of Korea, was made to reveal the distribution, provenance and dispersal pattern of fine-grained sediments. Additional nine samples were also taken from the Choryang Cheon (a river draining the kaolin-rich Hadong area) to investigate the influence of river a discharge. Grain size analysis for the Chinju Bay sediment samples was performed simultaneously as an aid to understand the sediment types and depositional environments. Except for the northeastern part, clayey mud predominates the entire bay. Average relative abundance of the four major clay minerals, I. I., illite, kaolinite, chlorite and smectite, is $55.1\%,\;23\%,\;21.5\%\;and\;0.4\%$, respectively. Although illite dominant clay mineral, the average content is about $10\~20\%$ tourer than that of the nearby continental shelf area. On the contrary, kaolinite content in the bay is about $10\%$ higher than that of the shelf area. Recent clay minerals of the Chinju Bay are mainly derived from the nearby inland area through numerous rivers and streams. Transport from shelf area, however. also seems to be important.
