In this study, quality characteristics of yogurt supplemented with Angelica gigas Nakai leaf extract were examined. The pH of the yogurt ranged from 4.40 to 4.45 and the titratable acidity ranged from 0.96% to 0.98%. The viscosity tended to decrease with the addition of the Angelica gigas Nakai leaf extract, but did not affect stability during storage. In the range of 0.1% to 0.3%, lactic acid bacteria were present in the range of 1.9×10⁹ to 3.2×10⁹ CFU/mL. The decursin content in yogurt was quantitatively analyzed, depending on the addition of 0.1% to 0.3% of Angelica gigas Nakai leaf extract and was found to be 0.26 ㎍/g, 15.23 ㎍/g, and 23.57 ㎍/g respectively. Organic acid showed the highest generation of lactic acid. The antioxidant properties of yogurt were shown to increase with the addition of the Angelica gigas Nakai leaf extract. The sensory score of yogurt supplemented with 0.1% of the Angelica gigas Nakai leaf extract was highly valued, at a level similar to that of plain yogurt. Yogurt supplemented with 0.2% of the extract was rated above the normal score of 6.31 to 6.50. As shown by the results, the optimal concentration of Angelica gigas Nakai leaf extract for addition to yogurt was within 0.2%.

Interest in all kinds of renewable energies has been highly increased while the micro-small-hydro power(MSHP) development has shown relatively slowly growth because of the negative public recognition about dam site development. It is, however, announced that the micro-SHP shows higher energy conversion efficiency compared to other renewable energies and does not emit any carbon dioxide. Thus, it is concerned about the development and application of micro-SHP as an alternative energy. In this study, the application for Android was exploited with Eclipse to visualize readily the potential realizable amount of hydropower by micro-SHP. With this application, we can select the region from the map, obtain the design discharge of the selected site was calculated with HEC-HMS, presented by U.S. Army of Corp. and perform the simply economic analysis in sequence. Yeongwol in Gangwon-do Province, Korea was chosen as the target area since historically abundant precipitation was found and it is possible to obtain fundamental data from WAMIS. Results from this study could be expanded the whole region of Korea. Also, the initial investment cost would be reduced if the location for micro-SHP would be determined properly, because this application can help us easily select and examine the potential micro-SHP sites without on-the-spot visit.

Absolute ages for three pieces of organic materials such as wood and shell were determined with radio-carbon concentrations and two potsherds with thermoluminescence measurements. Radiocarbon contents of each sample were compared with those of modern standard oxalate(NBS SRM4990C) and calculated radiocarbon ages of them. Quartz grains with diameter of $90\sim150{\mu}m$ were extracted from potsherds and used for measuring the archaeodose. Annual dose were calculated with measuring the alpha count rates and water contents and analysing $K_2O$ concentration of both potsherds and soils. Radiocarbon ages of organic materials were in the ranges of $4\sim2C$ BC and Quartz grain techniques for thermoluminescence dating showed 170 BC ud 210 BC respectively. It was found that the results of radiocarbon dating and TL dating were accorded with each other. But the deviations of TL dating have shown 13% and 20% respectively. It need to reduce the deviations.

Recently, the need for research into environmental and intrapsychic variables to promote active career preparation behavior is increasing, due to the increasing need to cultivate career preparation behavior starting from middle school. On the basis of this need, the purpose of this study is to identify the mediating effects of hope in the relationship between maternal learning involvement and career preparation behavior among middle school students. We surveyed 320 middle school students in W city, Gangwon-do, regarding these variables. We evaluated the results according to Baron and Kenny's (1986) mediating effect test procedure. The findings showed a significant positive correlation between positive maternal learning involvement, such as respecting their children's learning methods and providing academic information and advice, and the students' career preparation behavior and hope. However, the findings didn't show any significant correlation between negative maternal learning involvement, such as pressure for academic performance, and the students' career preparation and hope. Furthermore, hope was found to partially mediate the relationship between maternal positive learning involvement, including academic information and advice, and career preparation behavior, while fully mediating the relationship between career preparation behavior and respecting the students' learning methods. However, it did not have any mediating effect on the relationship between pressure for academic performance and career preparation behavior. These results highlight the important role that instilling hope in students, through respecting their learning methods and advising and providing the necessary academic information, plays in achieving a higher level of career preparation behavior.

We found an unrecorded species, Carex molestiformis Reznicek & Rothrock, in Byeokparyeong, Daehwa-myeon, Pyeongchang-gun, Gangwon-do, South Korea. This species is native to southern parts of the United States (ca. 11 states, including Arkansas, Missouri, and Oklahoma). These plants are usually distributed densely in stream flood plains, bottomlands, stream banks, and along roadsides. Belonging to section Ovales Kunth, perennial herbs with gynecandrous spikes, C. molestiformis is closely related to C. maackii Maxim. and C. scoparia Willd. and is distinguished from them by the number (2-4) of spikes in each inflorescence and the width (2.63.4 mm) and number (69) of veins of perigynia. A new Korean name of C. molestiformis 'Ga-Neun-Ta-Rae-Sa-Cho' was given, as it has slender overall appearance compared with C. maackii (Ta-Rae-Sa-Cho). We also provide a description, illustrations, photographs and a key of related taxa in Korea. We compared three DNA barcode region (chloroplast DNA matK, ndhF and nuclear ribosomal DNA internal transcribed spacer) sequences from C. molestiformis with those of C. maackii and C. scoparia, determining eight species-specific single nucleotide polymorphism sites for C. molestiformis.

Three species, Gymnogobius urotaenia, G. sp. 1 and G. sp. 2, which were collected at Hosanriver, Hosan-ri, Samcheock-si, Gangwon-do, Korea, were examined for study of the age and growth. There was no differences between sexes in growth (p>0.05) except in age 0 of G. urotaenia, However, there were differences among the three species (p<0.0001). namely, G. sp. 1 was longer by about 5~10 mm (SL) than the other two species in each age group, while G. sp. 2 was shortest in each age group: G. rotaenia, at age 0 was less than 45 mm, at age 1 to be 45~60 mm, at age 2 to be 60~80 mm, at age 3 to be over 80 mm, and its maximum size was 105.0 mm. G. sp. 1, at age 0 was less than 55 mm, at age 1 55~65 mm, at age 2 65~85 mm, at age 3 over 85 mm and its maximum size was 105.3 mm. G. sp. 2, 0 age was less than 40 mm, at age 1 40~55 mm, at age 2 55~75 mm, at age 3 over 75 mm and its maximum size was 85 mm. Changes of body parts with increasing of body length were examined and analyzed. Covariance analysis showed interspecies differences in the following characters: body depth, head length, caudal peduncle depth, upper jaw length and pelvic fin ray length. G. urotaenia had the highest K-value (the relative growth coefficient) in head length and pelvic fin ray length, and G. sp. 1 had the highest in body depth, caudal peduncle depth and upper jaw length. However, G. sp. 2 had the lowest K-value in these 5 characters.
