Although acute traumatic fractures of the clavicle are relatively common, stress fractures of the proximal clavicle are extremely rare. Stress fractures of the clavicle have often been reported after a radical neck dissection or radiation but rarely occur during excessive repetitive exercise in professional athletes. The authors report a case of a stress fracture of the proximal clavicle during exercise in a young man with no specific preceding factors, which has not been reported in the Korean literature.

These experiments are being conducted to obtain data of plant height, panicle length, heading date, number of culm, and fresh and dry weight, crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN) by six times seeding of 10 days interval ranging from May 1st to June 21st for two types of barnyard millet from the Suwon area in Korea. In the early-heading type, IT 170609 (Echinochloa crus-galli), the plant height and the number of culm per square meters are decreased by late seeding relatively, and heading date is 7 to 10 days earlier than the late seeding. And the dry weight of forage is rapidly decreased after the June 11th seeding. In the late-heading type, IT 195422 (Echinochloa frumentacea), the plant height and the number of culm per square meters are also decreased by late seeding relatively, and heading date is about 13 days earlier than late seeding. The dry weight of forage was rapidly decreased after the June 11th seeding. In both two types, the nutritive value of ADF, NDF, and TDN are not changed by late seeding, but crude protein is increased by late seeding. The TDN yields of late-heading type, IT 195400, show average amounts in the June 1st seeding, but the TDN yield of early-heading type, IT 170606, indicate safety amounts of dry weight to the March 21st seeding. And these data are available for cropping systems, cultivating barnyard millet in summer and cereals for forage in winter, to get high production of forage in Korea.

This study investigated the effects of sea tangle powder (SP) on the physicochemical and sensory characteristics of dumpling shells. Various dumpling shell samples were prepared with wheat flour containing different amounts of SP. The characteristics of the dumpling shell samples were investigated based on their viscosity, cooking properties, color values, and texture properties. Their sensory characteristics were evaluated by using seven scores. According to the amylograph data, the composite SP-wheat flour samples showed an increased gelatinization temperature with an increasing SP content, whereas the initial viscosity at $95^{\circ}C$ was decreased after 15 minutes. The increase of SP amount decreased the values of L and b whereas the a value increased. With regard to the textural characteristics, the dumpling shells with an increased amount of SP showed increased hardness, cohesiveness, and adhesiveness, whereas the SP addition reduced the springiness of the dumpling shell. The dumpling shell with the addition of 3% SP showed the highest overall acceptability in the sensory evaluation.

We described a spatial distribution pattern and floral diversity on the Paspalum distichum community occurring at the ecological parks of Hwamyeong, Daejeo, Samnak, and Maekdo in the Nakdong river estuary. A total distribution area of P. distichum community was $303,462.6m^2$. Its largest area was found in Samnak eco-park ($185,910.1m^2$). The most richness of knotgrass patches in each ecological park was determined Maekdo eco-park (87). Cover class level-5 shows the largest area ($260,663.2m^2$). A total of 73 taxa (34 families, 55 genus, 65 species, and 8 varieties) were listed up on the P. distichum community. A welldeveloped population of knotgrass was found predominantly at sites linked into human impacts at the riverine floodplain, the stream courses flowing through the parks, and the man-made channels and wetlands. Finally we proposed an ecological management strategy for knotgrass population in the study area.

The effects of barnyard millet (Echinochloa spp.) content (10~30%) on wheat flour dough and noodle properties were investigated. As the amount of barnyard millet increased, the particle size and ash content of mixed flour increased, while lightness tended to decrease. The gelatinization characteristics of millet flour showed higher peak viscosity, holding strength, final viscosity, and setback compared with wheat flour. There was significant positive correlation between protein content and sedimentation volume, as well as between protein content and water absorption. As the amount of barnyard millet increased, hardness, springiness and cohesiveness of wet noodles tended to decrease. From the results of sensory evaluation, composite flours (addition up to 20% barnyard millet) were rated with a quality score for taste and overall acceptance which was comparable with the control flour.

In order to evaluate undrained shear strength of clayey soils using Piezocone Penetration Test (CPTu), piezoncone factor is utilized. Commonly, piezoncone factors determined by empirical basis were preferred, which were established by correlation between measurements of piezocone test and undrained strengths obtained from other shearing tests. However, previous studies on the empirical piezocone factors were site-specific and there have been no systematic investigations on the effect of both engineering characteristics of clayey soils and soil non-homogeneity on the piezocone factor. Accordingly, the direct application of the previous results to Korean clayey soils without verification may be inappropriate. In this study, empirical piezocone factors are evaluated by comparing 46 CPTu results of 10 test sites with undrained shear strength obtained from Field Vane Test (FVT) and laboratory triaxial tests. Their reliabilities are investigated by the comparison with the previous piezocone factors and the deviation of data distribution from the mean values. And the effects of referencing test methods and typical engineering characteristics of clayey soils such as overconsolidation ratio (OCR) and plastic Index (I$_{p}$) are examined. Because piezocone factors obtained for various soil conditions are widely distributed, it is not appropriate to use the mean value as a representative. Instead, it is recommended to apply the piezocone factors with OCR, which is found to be a major factor in deriving piezocone factor. The necessitated piezocone factors are presented.d.

The purpose of this study was to evaluate cookies added with aged black chestnut inner shells powder (ABCI). Cookies were prepared with three different levels (0.25%, 0.5%, or 1%) of ABCI. During storage, moisture content was higher in cookies containing ABCI compared with control cookies. As the amount of ABCI increased, pH of cookies added with ABCI decreased slightly, whereas acidity increased. The lightness and yellowness in the Hunter color system of cookies with ABCI decreased during storage, whereas redness increased during storage. Higher reducing sugar was contained in cookies with ABCI than in the control. Textural properties by texture profile analysis showed that hardness and chewiness decreased with an increase in ABCI amount. Total phenol content increased in cookies with ABCI. Antioxidant activities such as diphenyl picrylhydrazyl radical and hydroxyl radical scavenging activities increased in cookies with ABCI compared with that of the control. It is concluded that cookies with ABCI may be of high quality with antioxidant activity. In the preference test, cookies added with 0.5% ABCI showed the high results in terms of overall preference and buying intention.

피조개(Scapharca broughtonii)는 우리나라 동해안 북부에서 남해안과 서해안의 내만에 널리 분포하는 고막류 가운데 가장 중요한 산업종으로서 주로 남해안에서 많이 양식하고 있다(강 등, 1980: 김 등, 1982). 또한, 피조개의 자연채묘 및 양식기술이 확립된 이후 주로 강진만, 가막만, 득량만 등에서 양식이 되고 있다. 특히, 가막만에서는 1990년대 이후 피조개 종패가 매년 채묘되고 있으나 중간양성중 대부분이 폐사되거나 탈락되어 종패로서 활용하지 못하고 있다. (중략)

This study was conducted to find out if there are some differences in germination, growth and morphological characteristics between rice(Oryza saliva) and barnyardgrass(Echinochloa crus-galli) under various cropping patterns and to abtain the fundamental information on weed control method in direct seeded rice. Rice was broadcast on soil-surface(Broadcast rice), drill seeded in soil(Drilled rice) and barnyardgrass was drill seeded in soil(Barnyardgrass) under dry(Dry condition) and water direct seeded condition(Water condition). Also rice was transplanted with 8-day seedlings(8 -day-old seedling) and 25-day seedlings(25-*day-old seedling) under transplanting condition(Transplanting condition) At 1, 2, 3, 5, 7, 10, 15 and 20 days after seeding or transplanting(DAS/T), plants were harvested to examine their germination, growth and morphology. The major results were as follows ; Until 5 DAS/T growth of rice and barnyardgrass were well established under dry condition but under water condition growth of shoots was mainly elongated. At 20 DAS/T barnyardgrass had greater plant height and shoot fresh weight than rice under direct seeded condition, while plant height and shoot fresh weight of rice was greater than those of barnyardgrass under transplanting condition. Root length of barnyardgrass was greater under the dry, drilled, direct seeded conditions than that of rice under the water, broadcast, transplanting condition, respectively. And root fresh weight of rice under direct seeded condition was similar to that of barnyardgrass but that of rice under transplanting condition was significantly greater than that of barnyardgrass. Barnyardgrass only formed mesocotyls and its length increased with increased depth of seeding. Leaf stage and leaf area of barnyardgrass was greater under the dry, drilled than those of rice under water, broadcast conditions, respectively, while those of rice was greater than those of barnyardgrass under transplanting condition. Chlorophyll contents were higher in barnyardgrass, dry direct seeded rice, transplanted rice, water direct seeded rice in descending order.
