  • Variation in relative contents of clay minerals was used to genetically interpret depositional environment of the Upper Jurassic Solnhofen limestone. Mineralogical examination of whole rocks and clay fractions indicates that the faule and flinz beds are composed mainly of calcite and quartz with minor amount of clay minerals such as illite, kaolinite, and smectite. Smectite shows a trend of illitization: illite layers increase with increasing of burial depth. With increasing burial depth, relative abundance of kaolinite with quartz and illite increases. This implies that the Solnhofen basin was formed during the transgression based on reduce of terrigenous influx.

  • Since the beginning of history, men have done mimesis and produced illusion and succeeded art and culture instinctually. The subject which mention above included the object which can order and space around that. Perspective which began the Renaissance age was dominant way about understanding space in western history and it made modern visual system. Direction way of space which based perspective is changed as horizontal data included multi-layer structure in digital media age. This character make us possible to represent the space more efficiently. So we must have pay attention the direction way of space based on digital media, because it has meaning to show human value beyond a methodology of visual art culture.

  • In this paper, the incorporation of qualitative(or soft) data, such as outputs of geophysical tests or construction experience which has so far been cumulated, was discussed for rock classsification. Geostatistics wart used for this research since the parameters for the design of tunnels are spatially correlated. In particular, indicator kriging technique, which is one of non -parametric approaches, was used. As a selection criteria for an optimal classification, the cost of errors was adopted and the binary classes were only considered for rock classification. In future, incorporating an appreciable amount of available qualitative data will be necessary in tunnelling projects in which quantitative data are scarce. In this respect, this research is of great significance.

  • 스발바드 서측에 위치하는 스피츠버겐 하부의 암석권맨틀의 분화시기를 규명하기 위하여, 두 개의 독립적인 방사성동위원소 시스템인 Lu-Hf과 Re-Os 시스템을 스피넬 페리도타이트(spinel peridotite)에 활용하였다. 전암에 대한 Re-Os 계통(Re-Os 에러크론, 알루미노크론, Re-결핍연대 등)은 연구지역의 페리도타이트가 대류하는 맨틀로부터 고기원생대/후기시생대에 분리되었음을 지시한다. 흥미롭게도 이런 연대는 페리도타이트내 단사휘석 결정들에 대하여 얻어진 Lu-Hf 에러크론 연대와 일치한다. 또한 시료 내에 지구화학적으로 기록된 현무암질 액의 결핍정도 역시 계통적으로 위의 연대를 지지한다. 위 연대는 스피츠버겐 서측부에 보고된 가장 오래된 지각의 연대와 일치한다. 따라서 연구지역의 암석권맨틀이 연약권으로부터 분리된 것은 접촉하고 있는 지각과 동시기적으로 이루어진 사건임을 알 수 있다. 연구지역은 팔레오세 이래로 복잡한 지구조적 응력장 변화(압축에서 신장환경으로의 변화)를 겪었다. 그럼에도 불구하고 지각과 커플링된 암석권맨틀이 현존한다는 것은 연구지역내 응력장변화가 대규모의 암석권 디라미네이션(delamination)을 유발하지는 않았다는 것을 의미한다. 그러므로 북극권의 화산활동을 설명하기 위하여 북극권 상부맨틀에 존재한다고 알려진 듀팔(DUPAL) 같은 부화된 물질의 성인으로 일부의 연구자들이 주장하여 온 디라미네이션된 암석권맨틀의 존재는 설득력이 없다고 판단된다.

  • This study tries to present a new perspective for the coding and coding education. Therefore, this study analyzes coding game as performative writing. First, coding as writing process has the mechanism of serial expansion and circulation by utilizing basic code blocks. And coding as writing process produces a meaning as unit operation that generate an emergent game play. Second, coding as performative writing displays the speaking and writing at the same time and is embodied in game play. Also, absence of failure and correction makes possible users to explore the problem area and to strengthen the problem-solving ability.

  • 대규모 언어 모델은 높은 연산 능력과 방대한 양의 데이터를 기반으로 탁월한 성능을 보이며 자연어처리 분야의 주목을 받고있다. 이러한 모델들은 다양한 언어와 도메인의 텍스트를 처리하는 능력을 갖추게 되었지만, 전체 학습 데이터 중에서 한국어 데이터의 비중은 여전히 미미하다. 결과적으로 이는 대규모 언어 모델이 영어와 같은 주요 언어들에 비해 한국어에 대한 이해와 처리 능력이 상대적으로 부족함을 의미한다. 본 논문은 이러한 문제점을 중심으로, 대규모 언어 모델의 한국어 처리 능력을 향상시키는 방법을 제안한다. 특히, Cross-lingual transfer learning 기법을 활용하여 모델이 다양한 언어에 대한 지식을 한국어로 전이시켜 성능을 향상시키는 방안을 탐구하였다. 이를 통해 모델은 기존의 다양한 언어에 대한 손실을 최소화 하면서도 한국어에 대한 처리 능력을 상당히 향상시켰다. 실험 결과, 해당 기법을 적용한 모델은 기존 모델 대비 nsmc데이터에서 2배 이상의 성능 향상을 보이며, 특히 복잡한 한국어 구조와 문맥 이해에서 큰 발전을 보였다. 이러한 연구는 대규모 언어 모델을 활용한 한국어 적용 향상에 기여할 것으로 기대 된다.

  • Language has a social function to communicate information. Linguists have gradually paid their attention to the function of language since the nineteen sixties, especially to the relationship of form, meaning and the function. The relationship could be more clearly grasped through disciyrse-based analysis than through sentence-based analysis. Many researches were centered on the discourse functional notion of topic. In the early 1970's the subject was defined as the grammatiocalized topic the topic as a discrete single constituent of the clause. In the late 1970's several lingusts including Givon suggerted that the topic was not an atomic, disctete entity, and that the clause could have more than one topic. The purpose of the present study is, following Givon, to study grammatical coding devices of topic and to measure the relative topic continuity/discontinuity of participant argu, ents in Korean narratives. By so doing, I would like to shed some light on effective ways of communicating information. The grammatical coding devices analyzed are the following eight structures: zero-anaphora, personal pronous, demonstrative pronouns, names, noun phrases following demonstratives, noun phrases following possessives, definite noun phrases and indefinite referentials. The narrative studied for the count was taken from the KoreanCIA chief's Testiomny:Revolution and Idol by Hyung Wook Kim. It was chosen because it was assumed that Kim's purpose in the novel was to tell a true story, which would not distort the natural use of language for literary effect. The measures taken in the analysis wre those of 'lookback', 'persistence', ambiguity'. The first of these, 'lookback', is a measure of the size of gap between the previous occurrence of a referent and its current occurence in the clause. The meausure of persistence, which is a measure of the speaker's topocal intent, reflects the topic's importance in the discourse. The third measure is a measure of ambiguity. This is necessary for assessing the disruptive effects that other topics within five previous clauses may have on topic identification. The more other topics are present within five previous clauses, the more difficult is the task of correct identification of a topic. The results of the present study show that the humanness of entities is the most powerful factior in topic continutiy in narrative discourse. The semantic roles of human arguments in narrative discourse tend to be agents or experiences. Since agents and experiences have high topicality in discourse, human entities clearly become clausal or discoursal topics. The results also show that the grammatical devices signal varying degrees of topic continuity discontinuity in continuous discourse. The more continuous a topic argument is, the less it is coded. For example, personal pronouns have the most continutiy and indefinite referentials have the least continutiy. The study strongly shows that topic continuity discontinutiy is controlled not only by grammatical devices available in the language but by socio-cultural factors and writer's intentions.

  • A total of 50 diatom species and 1 subspecies belonging to 31 genera except Chaetoceros resting spores were identified in the 45 sediments subsampled from a gravity core GH98-1223 collected from the western Hokkaido Island located in the northeastern East Sea (Sea of Japan). The most dominant species is Thalassionema nitzschioides (Grunow) Hustedt, ranging 29 to 59% of the total assemblages, and most species including Denticulopsis seminae (Simonsen and Kanaya) Simonsen and Pseudoeunotia doliolus (Wallich) Grunow were less than 5% in average. Frequencies of cold-water species are generally higher than those of warm-water species and the vertical distribution of cold-water species was largely opposite to that of warm-water species in spite of ecological habitat difference. Frequency of cold-water species, D. seminae is reverse to that of P. doliolus, an indicator of the Tsushima Warm Current, which is consistent with diatom temperature value (T$_{d}$ value). The variation of T$_{d}$ values shows that the upper part of core with greater-than-average T$_{d}$ values represents postglacial warming trend. These T$_{d}$ values clearly demonstrate that the study area located in the northern part of the East Sea is gradually influenced by Tsushima Warm Current. In addition, the zig-zag variation in the lower part reflects the unstable seawater for diatom habitat. Chaetoceros resting spores indicating productivity and upwelling was 5.3 to 40%, with maximum peak at 80 cm. Chaetoceros resting spores/Chaetoceros vegetative cells, an indicator of relative amounts of biogenic material in the sediments was high at the upper 80 cm level, corresponding to the change of T$_{d}$ values. On the basis of diatom assemblages, the northeastern part of East Sea has experienced the effects of Tsushima Warm Current during the postglacial period of Holocene, which is similar to the modem climatic environment. However, the variation of P. doliolus reflects that the intensity of Tsushima Warm Current has been oscillated in the East Sea.

  • This study investigated soil carbon storage and microbial activities influenced by different management practices in rice paddies and pastures. Soils under a single-crop farming of rice (CON) and rice-Italian ryegrass rotation farming (IRG) were compared in Jangheung, Jeollanam-do, Seocheon and Cheonan, Chungcheongnam-do. Soils from pastures were analyzed to investigate the effect of duration period (P1, P2, P3) in Namwon, Jeollabuk-do and Seosan, Chungcheongnam-do. In rice paddy, total and particulate carbon (PC) concentrations in the IRG soils were significantly higher than those in the CON soils both in Jangheung and Seocheon where the IRG has been established for three years, whereas carbon concentrations were not significantly different in Cheonan where IRG planting history is only one year. In rice paddy soils, PC was suggested as an early indicator to monitor changes in soil carbon storage followed by adopting different management practices. In pasture, total and PC concentrations increased with duration period especially in the 0-5 cm soils. Contrary to the rice paddy soils, the magnitude of change in PC concentration is not as great as that in total carbon concentration, implying that there is a need to develop a new early indicator other than PC using different fractionation scheme. The soil carbon storage in pasture also increased with years since establishment and the increasing rate was significantly greater in the early stage (0-5 yrs) than the later one (> 5 yrs). Microbial activities measured from fluorescein diacetate (FDA) hydrolysis analysis were significantly lower in the IRG soils than CON soils, whereas no difference was observed in the pastures of different ages. This shows that FDA activity is not a sensitive indicator to differentiate soil qualities influenced by management practices if it is used by itself.

  • Information-giving is very important skill in career education and career counseling. The purpose of this study was to analyse the definition and method of information-giving as a important counseling skills in the counseling textbooks. Research questions were as follows: First, what is the definition of information-giving? Second, what are the ways to give the information in counseling? 17 textbooks of counseling were reviewed. The following are the main findings. First, the definition of information-giving was summarized in two ways: (1) the meaning of information (2) the description of information-giving. The results revealed the reason why the definition of information-giving is vague and it is difficult to distinguish from other skills (ex: giving advice, providing interpretation). Second, the main methods of information-giving can be summarized as follows: (1) motivation and timing of information-giving (2) selection criteria of information-giving (3) procedure of information-giving (4) considerations of information-giving. Out of these methods, the textbooks do not provide much reference on 'selection criteria of information-giving and procedure of information-giving. These findings revealed the necessity of empirical study on the information-giving skills.
