  • We present a 3D SH-wave velocity model of the crust and uppermost mantle and seismic radial anisotropy beneath East Asia. The SH-wave velocity structure model was built using Love-wave group-velocity dispersion data from earthquake data recorded at broadband seismic networks of Korea, Japan, and China. Love-wave group-velocity dispersion curves were obtained by using the multiple filtering technique in the period range of 3 to 150 s for 3,369 event-station pairs. The inverted model using these data sets provides a crust and upper mantle SH-wave velocity structure down to 100 km depth. At 10 ~ 40 km depths SH-wave velocity beneath the East Sea is higher than beneath the Japanese island region. We estimated the Moho beneath the East Sea to be between 10 ~ 20 km depth, while Moho beneath the Korean Peninsula at around 35 km based on the depth where high-velocity anomalies are detected. We estimated the lithosphere-asthenosphere boundary beneath the East Sea to be at around 50 km based on the depth where strong low-velocity anomalies are observed. Widespread low-velocity anomalies are found between 50 ~ 100 km depth in the study region. Positive radial anisotropy ($V_{SV}$ > $V _{SH}$) is observed down to 35 km depth, while negative radial anisotropy ($V_{SV}$ > $V _{SH}$) is observed for deeper depth.

  • 야외지질학습은 교실에서 경험할 수 없는 물질과 현상을 관찰하고 직접 경험할 수 있는 기회를 제공받을 수 있어서 매우 중요하다(Orion 1989). 또한 체험활동으로서 교실에서 학습한 내용의 구체적인 예를 제공하여 교육과정을 촉진시키는데 중요한 요소로 인식되고 있다. 일반적으로 야외 활동은 교실 활동보다 학생들의 경험과 훨씬 더 밀접히 관련되어 있기 때문에 보다 의미가 있을 수 있다. 야외실습 중에서 얻은 경험은 학생들이 그가 관찰한 것에 대해 읽도록 동기화시키고, 교과서와 자연조건에서의 실제적 경험 사이의 차이를 연결해 주는 다리를 제공해 줄 수 있다(홍정수, 장남기, 1997). 야외학습을 위한 적절한 장소는 먼저 학습주제나 목표와 부합되는 곳이어야 하며, 지리적으로 가깝고 안전한 곳이어야 한다(김찬종, 2008). 그렇기 때문에 각 지역별로 학습주제와 부합된 지역을 선정하여 야외지질 학습자료를 개발하는 것은 무엇보다 중요하다. 따라서, 본 연구에서는 전북 남원 일대를 중심으로 한 야외지질 학습자료를 개발하는데 그 목적이 있다. 전북 남원지역은 한반도의 중요지괴에 해당하는 영남육괴 지리산지구에 해당하며 편마암 복합체를 기저로 이를 관입하는 수 차례의 화성활동과 지구조운동으로 복잡한 지질양상을 보인다. 또한 지리산 지역은 평안분지와 경상분지의 일부가 보존되어 있고 지질시대를 달리하는 각종 화성암류가 골고루 분포하여 각 지질시대별로 화성활동과 지구조 운동이 활발했음을 시사해준다. 본 연구에서는 남원 지역의 지질학적 특징을 관찰하기 용이한 지역을 대상으로 총 5곳을 선정하였다. 남원 시내에 소재한 춘향대교 아래 지역은 중생대 쥐라기에 관입한 저반상의 남원화강암과 페그마타이트가 다수 분포하는 곳이다. 이 지역에서는 무수히 많은 관입암체를 찾을 수 있는데 다수의 지진과 지각변동이 있었음을 알 수 있다. 두 번째 장소는 다양한 바위들을 관찰할 수 있는 구룡계곡 일대이다. 이 장소는 오랜기간 동안 물의 흐름에 의해 풍화와 침식을 받은 다양한 크기의 바위를 관찰하고 구별함으로써 풍화에 따른 원마도의 관계, 바위들의 배치 형태를 통해 고지형 및 고수류의 방향을 유추해 볼 수 있다. 남원에서 장수 방향에 위치한 만행산 주변에는 흑운모편마암에 우세한데, 이 지역에서는 흑운모편마암에 나타나는 변성구조로 볼 때 높은 열과 압력을 받은 광역변성작용을 받는 것으로 판단된다. 또한 관입암체 내에 다양한 맥들이 관입을 해와 이를 통해 관입암체들의 상대연령을 판단해보는 학습자료로 활용될 수 있다. 네 번째 장소는 남원시 인월면 인풍리 소재의 인월 피바위 지역이다. 이 지역에서는 압쇄상 화강암이 주로 관찰되는데 이는 기원암인 반상화강암이 동력변성작용을 받아 생성된 것이다. 다섯 번째 지역은 지리산 내의 뱀사골로 지리산 인근에 분포하는 대표적인 편마암인 반상변정질 편마암을 관찰할 수 있다. 변정이란 변성작용을 받는 동안 형성되는 것으로 변성작용을 받는 동안 생긴 것도 있으나 경우에 따라 생성당시 원래 모암속에 포함되어 있는 반정들도 있다.

  • The granites in the Jeomchon area can be divided into hornblende biotite granite (Hbgr), deformed biotite granite (Dbgr), deformed pinkish biotite granite(Dpbgr), biotite granite (Btgr), and granite porphyry(Gp). These granites show metaluminous, 1-type and calc-alkaine characteristics from their whole-rock chemistry. Hbgr and Dbgr belong to ilmenite-series granitoids, but Gp to magnetite-series. Dpbgr and Btgr show the intermediate nature between ilmenite- and magnetite-series. Tectonic discriminations indicate that Hbgr and Dbgr were formed in active continental margin environment, whereas Dpbgr, Btgr, and Gp in post-orogenic and/or anorogenic rift-related environment. From the Harker diagrams major oxide contents of Hbgr and Dbgr show a continuous variation with $SiO_2$, indicating that they are genetically correlated with each other. On the other hand, any correlation of major oxides variation cannot be recognized among Dpbgr, Btgr and Gp. It seems like that Hbgr and Dbgr were derived from a same parent granitic magma, judging from their occurrence of outcrop, mineral composition as well as whole-rock chemistry. Variation trends of major oxide contents between Hbgr and Baegnok granodiorite are very similar and continuous. If the two granites were derived from a cogenetic magma, there exists a possibility that the granitic bodies had been separated by Btgr and Gp of Cretaceous age. Three stages of the granitic intrusions are understood in the Jeomchon area. After the intrusion of Hbgr and Dbgr during middle to late Paleozoic time, Dpbgr emplaced into the area next, and finally Btgr and Gp intruded during Cretaceous time. Tectonic movement accompanying shear and/or thrust deformation seems likely to have occurred bewteen the intrusions of Dpbgr and Btgr.

  • Seasonal succession of zooplankton community and species composition was studied from 2003 to 2014 in a deep reservoir, Lake Soyang, in monsoon climate region, Korea. Annual precipitation was concentrated more than 70% between June and September and it showed remarkably that seasonal variation in water quality. Seasonal variation of water quality in Lake Soyang appeared to be more significant than annual variations, and the inflow of turbid water during the summer rainfall was the most important environmental factor. Zooplankton sepecies composition in Lake Soyang showed obvious tendency through two periods (May to June and August to October) every year. Small zooplankton (rotifer; Keratella cochlearis, Polyarthra vulgaris) dominated in spring and mesozooplankton such as copepods and crustaceans were dominant in summer and fall. Zooplankton biomass showed the maximum in September after monsoon rainfall, and chlorophyll showed a similar seasonal variation and it showed a high correlation (r=0.45). The increase of zooplankton biomass is considered to be a bottom-up effect due to the increase of primary producers and inflow of nutrients and organic matter from rainfall. In this study, we found that the variation of zooplankton community was affected by rainfall in monsoon climate region and inflow of turbid water was an important environmental factor, which influenced the water quality, zooplankton seasonal succession in Lake Soyang. It was also considered to be influenced by hydrological characteristics of lake and environment of watershed. In conclusion, seasonal succession of zooplankton species composition was the same as the PEG model. But seasonal succession of zooplankton biomass differed not only in the temperate lake but also in the monsoon region.

  • Simon and Sullivan(l993) estimated that clothing and textile related brand equity had the highest magnitude comparing any other industry category. It reflects that fashion brands reinforce the symbolic, social values and emotional characteristics being different from generic brands. Recently, Kim and Lim(2002) developed a fashion brand equity scale to measure a brand's psychometric properties. However, they suggested that additional psychometric tests were needed to compare the relative magnitude of each brand's equity. The purpose of this study was to recognize the psychometric constructs of fashion brand equity and validate Kim and Lim's fashion brand equity scale using the measurement invariance test of cross-group comparison. First, we identified the constructs of fashion brand equity using confirmatory factor analysis through structural equation modeling. Second, we compared the relative magnitude of two brands' equity using the measurement invariance test of multi-group simultaneous factor analysis. Data were collected at six major universities in Seoul, Korea. There were 696 usable surveys for data analysis. The results showed that fashion brand equity was comprised of 16 items representing six dimensions: customer-brand resonance, customer feeling, customer judgment, brand imagery, brand performance and brand awareness. Also, we could support the measurement invariance of two brands' equities by configural and metric invariance tests. There were significant differences in five constructs' mean values. The greatest difference was in customer feeling; the smallest, in customer judgment.

  • Objective: This study is a quasi-experimental study by nonequivalent control group pretest-posttest design, performed in order to identify whether the program developed on the basis of Ajzen(1988, 1991)'s theory of planned behavior (TPB) for predicting the safety behavior of students of department of dental technology affects intention toward safety behavior and general behavior. Therefore, the purpose of this study is to identify whether the safety education in laboratories in which knowledge is reinforced on the basis of the TPB theory affects safety behavior. Methodology: The theoretical framework of this study was established on the basis of the TPB by Ajzen(1988, 1991). This study was performed between May 20 and December 5, 2006, and the subjects included 101 in the experimental group and 98 in the control group, a total of 199. The experimental group was educated through six 50-minute sessions (twice a week) for three weeks. The experimental group was pretested, educated, and then asked to answer the pro-questionnaire after finishing the sixth session, but the control group was free from intervention. The research tool in this study was developed by the authors with reference to the process of tool development used in Schifter and Ajzen (1985) based on Ajzen and Fishbein(1980)'s tool development guide. Results: The data were analyzed through SPSS 14.0 version. The reliability test of attitude, subjective norm, perceived norm, intention, and behavior toward safety behavior as TPB variables was calculated of Cronbach's alpha coefficient, and general characteristics and the homogeneity test of the experimental and the control groups were analyzed through t test and $X^2$ test. According to the results of the analysis, the experiment group may be higher than the control group after the safety education in the scores of attitude, the subjective norm, the perceived norm, and the intention toward safety behavior as TPB independent variables showed no significant difference, but there was significant difference in the behavior and the knowledge. Meanwhile, according to the results of the pretest and posttest, eleven items in the experimental group and two items in the control group showed significant difference in the behaviors, and twelve in the former and four in the latter were significantly different in the knowledge. Conclusion: The safety education program developed on the basis of TPB was identified to enhance safety behavior and knowledge. Therefore, the safety education program used in this study for students of department of dental technology may be utilized as database for safety education in the department of dental technology.

Petrological Characteristics of Two-Mica Granites : Examples from Cheongsan, Inje-Hongcheon, Yeongju and Namwon areas (복운모 화강암의 암석화학적 특징 : 청산, 인제-홍천, 영주 및 남원지역의 예)

  • From their general natures of peraluminous, S-type and ilmenite-series granites, two-mica granites in the Cheongsan, Inje-Hongcheon, Yeongju and Namwon areas were originated from crust-derived granitic magma and solidified under reducing condition. Each two-mica granite in Inje-Hongcheon and Namwon districts was differentiated from the the residual magma of porphyric biotite granite and high Ti/Mg biotite granite, respectively. The genetic relationships between two-mica granite and porphyritic biotite granite in Chenongsan district and between two-mica granite and biotite granodiorite in Yeongju district are ambiguous. In Namwon district granitic magmas were water-saturated and possible water solubilities in magmas were more than 5.8wt.%. In Yeongju district two-mica granitic magma was nearly water-saturated and showed possible water solubilities between 2.4~5.8wt.%. Two-mica granitic magmas in Cheongsan and Inje-Hongcheon districts were water-undersaturated. Pressure-dependent minimum melt compositions (0.5~2kb) and petrographic textures of two-mica granites in Inje-Hongcheon and Yeongju districts represent that the granites intruded and solidified at shallow level, whereas those in Cheongsan and Namwon districts exhibit relatively deeper level of granitic intrusion (2-3kb). The intersection of granite-solidus/muscovite stability indicates that magmatic primary muscovite can be crystallized from the water-saturated magma above 1.6kb (ca. 6km), but below the pressure muscovite can be formed by the subsolidus reaction. On the other hand, more pressure would be necessary for the crystallization of primary muscovite from the water-undersaturated magma. This pressure condition can explain the occurrence of primary and secondary muscovites from the two-mica granites in the areas considered. The experimental muscovite stability must be cautious of the application to examine the origin of muscovite. The muscovite stability can move toward high temperature field with adding of Ti, Fe and Mg components to the octahedral site of pure muscovite end member.
