자동차 폐촉매의 침출액으로부터 백금족 금속의 분리를 위하여 용매추출에 대한 기초연구가 수행되었다. 추출제로 tri-n-butyl phosphate (TBP), tri-n-octylamine (TOA) 그리고 di-n-hexyl sulfide (DHS)를 등유에 희석하여 사용하였다. 추출제의 종류 및 농도가 백금, 팔라듐 그리고 로듐의 추출거동에 미치는 영향을 조사하였다. 또한 세륨, 납, 철, 마그네슘 그리고 알루미늄 등 침출액에 존재하는 주요 금속불순물의 추출거동도 함께 조사하였다. TBP는 백금과 팔라듐, 그리고 TOA는 백금, 팔라듐, 로듐을 동시에 추출하였다. DHS 추출제인 SFI-6에 의한 용매추출 시 백금이 팔라듐과 함께 유기상으로 추출되었으나, SFI-6R은 팔라듐만 선택적으로 추출하였다. SFI-6R은 SFI-6에 비하여 팔라듐에 대한 선택성이 우수하였으나 추출속도가 느렸다. 추출제의 종류에 따라 백금족 금속과 함께 추출되는 금속불순물들이 달라지며 세정 또는 탈거공정에서 이들을 제거하여야 한다. 자동차 폐촉매의 침출액으로부터 백금, 팔라듐 그리고 로듐을 분리하기 위하여 먼저 DHS 추출제인 SFI-6R를 사용하여 팔라듐을 분리한 다음 TBP 또는 TOA으로 백금을 추출하여 로듐과 분리하는 공정이 적절한 것으로 나타났다. The solvent extraction for the separation of platinum group metals from the leach liquor of spent automotive catalysts has been studied. Tri-n-butyl phosphate (TBP), tri-n-octylamine (TOA) and di-n-hexyl sulfide (DHS) were used as extractants and kerosene as a diluent. The extraction behavior of platinum, palladium and rhodium has been investigated as functions of different kinds of extractants and their concentrations. In addition, the extraction behavior of the major metal impurities such as cerium, lead, iron, magnesium and aluminum has been investigated. Platinum and palladium were extracted with TBP. And platinum, palladium and rhodium were extracted with TOA. Platinum was co-extracted with palladium into the organic phase by solvent extraction using SFI-6 of DHS extractant, but only palladium was selectively extracted with SFI-6R. The selective extraction of palladium with SFI-6R was found better than that with SFI-6, but the kinetics of extraction with SFI-6R was found poor in comparison to SFI-6. The metal impurities extracted simultaneously during the extraction of platinum group metals should be removed in scrubbing and stripping processes. A suitable process has been proposed for the separation of platinum group metals from the leach liquor of spent automotive catalysts. Initially palladium was extracted with SFI-6R, followed by the separation of platinum with TBP or TOA leaving rhodium in the raffinate.

Spiders are easily distinguished from all other creatures by behavior of making webs. Among the web building spiders which depend largely on their webs to predation, Atypidae, four species in Korea, uses the purse web which is the most primitive one than other spider`s web in Korea. To analyze the chemical properties of the purse web, 30 ㎎ of Atypus coreanus` web was collected in Joan-myun, Namyangjoo-city, Kyunggi-do. As a result, the purse web of Atypus coreanus mostly consists of Glycine (5.3%), Glutamic acid (8. 26%) and Alanine (14. 17%). Especially the web of Atypus coreanus has more proportion of serine (9.28%), which plays an important role in intricacy, than that of orb webs used by Nephila clavata(4.84%) and Araneus ventricosus(4.84%).

본 연구는 인지기능에 영향을 미칠 것으로 생각되는 성별, 질병유무, 운동유무, 그리고 연령에 따라 시지각과 시각-운동통합 능력이 어떻게 변화되는지를 조사하고 그 결과를 바탕으로 일반 성인의 시지각과 시각-운동통합 능력에 영향을 미치는 주요 요인을 규명하고자 시행되었다. 연구 대상자는 대구ㆍ경북에 거주하고 일상생활과 의사소통이 가능하며, 인지기능 장애가 없는 건강한 20-70대의 남녀 성인 137명으로 하였다. 시지각과 시각-운동통합 능력을 평가하기 위한 측정도구는 각각 MVPT-V, VMI-3R을 사용하였다. 연구결과 시지각 능력에는 성별(β=-.170, P=.012)과 연령이(β=-.614, P<.001), 시각-운동통합 능력에는 연령(β=-539, P<.001)이 가장 큰 영향을 주는 요인이었고, 특히 시각-운동통합 능력이 시지각 능력보다 연령에 더 크게 감소하는 것으로 나타났다(Wald's χ²=16.03, P<.001). 이러한 연구결과는 노화에 따른 인지기능의 감소가 시지각과 시각-운동통합 능력의 감소와 매우 밀접한 관련이 있으며, 따라서 노화에 따른 인지기능의 감소를 적절하게 예방하기 위해서는 연령에 따라 크게 감소하는 시각-운동통합 능력에 대한 적절한 평가와 효과적인 측정도구의 개발이 필요할 것으로 생각된다. The aim of this study was to investigate the change of visual perception (VP) and visual-motor integration (VMI) depending on various factors. The survey was conducted by 152 subjects (aged 20 to 70 years old; both gender, n=10 in each ages) living in Dague and Gyeongbuk district and 137 proper data were collected. Data were collected through interview-based questionnaires which were constructed to include the Motor Free Visual Perception Test-Vertical Format (MVPT-V) and the Visual-motor integration 3rd Revision (VMI-3R). Collected data were analyzed by frequency, t-test, one-way ANOVA, correlation, and regression analysis and most results were expressed the mean ± standard deviation (SD) or percentage (%). As a results, the main factors were gender and age on VP and age on VMI. Particularly, VMI is more affected by age than VP. In conclusion, this study suggests that the regular evaluation of VMI is very important to protect cognitive deficit by aging process effectively.

1457년 김시습의 행적(行迹)과 심경(心境)

이승수 ( Lee Seung Su ),황인건 ( Hwang In Geon ),김미애 ( Kim Mi Ae ),민선홍 ( Min Seon Hong ) 한국언어문화학회(구 한양어문학회) 2020 한국언어문화 Vol.0 No.73

이 글은 <遊關西錄> 소재 145제 165수의 시를 텍스트 삼아, 1457년 23살 김시습의 행적과 심경을 밝히는 것을 목적으로 한다. 김시습의 관서 유람 시기는 1458년으로 오인된 사례가 적지 않은데, <유관서록>에 등장하는 인물들을 고려하면 1457년으로 확정할 수 있다. 유람 여정은 이른 봄 洛河를 건너 송도와 평양 두 고도에서 한동안 머물다가 묘향산에 들어가 여름을 나고, 가을 초엽 묘향산을 나서는 것으로 이어졌다. <유관서록>은 이러한 시공간의 흐름에 따라 편집되어 있으며, 각 구간에 따라 심리와 미의식의 변화를 드러낸다. 멸망한 전대 왕조의 수도인 송도에서는 폐허에서의 허무를 체감했다. 신화적이며 낭만적인 도시 평양에서는 문명의 영화에 취했다. 묘향산에 들어가서는 하계를 내려다보며 흉금을 크게 틔우고, 그렇지 않을 때는 禪房에서 三昧에 들어 三生의 業緣을 끊어냈다. 이렇게 정돈된 마음으로 묘향산을 나선 뒤에는 승려로서의 정체성을 확고히 하는 동시에 유자들과 교유하면서, 한 지점에 머물지 않는 삶의 방식을 보였다. The purpose of this paper is to clarify the path and mood of 23-year-old Kim Si-seup(金時習) in 1457, by analyzing his poetical works < Yukwanseurok(遊關西錄) >. There are many cases that Kim Si-seup’s sightseeing time was mistaken for 1458. Considering the characters in < Yukwanseurok >, it can be confirmed in 1457. The trip was followed by crossing Nak River(洛河) in early spring, staying at Songdo(松都) and Pyongyang(平壤) for a while, entering Mt. Myohyang(妙香山) during summer, and leaving there in early autumn. < Yukwanseurok > is edited according to the flow of space-time, and each section represents psychological and aesthetic change of Kim Si-seup’s mind. In Songdo, the capital of the fallen dynasty, Kim Si-seup had an nihilistic experience. In Pyongyang, the mythical and romantic city, he felt the glory of civilization. In Mt. Myohyang, he looked down the world below and widened his heart. Otherwise, he entered into sam-mae(三昧) in Buddhist temple and cut the karma of three lifetimes. After leaving Mt. Myohyang with such an orderly mind, he solidified his identity as a monk. At the same time, while interacting with confucian scholars, he showed a way of life that was not limited to one point.

The Narrative of Woodcutter and Nymph」 is wildly known tale which is told and read from ancients times to now a days. And Also this tale is embodied the most commonly at the modern fairy tales. But After national division, North Korea The Narrative of Woodcutter and Nymph of North Korea differentiated into another perspective from original miracle tales, these phenomenon is caused by culture policy of north korea behind matter. In this study, the aspect of narration is studied in the The Narrative of Woodcutter and Nymph of North Korea and also take a deep inspection about originality of narration. This is the primary objective that the aspect of narration is investigated by looking for tradition of The Narrative of Woodcutter and Nymph which is not studied enough until now. And this study make an additional remark of limitation that can not study widely because study is based on data of North Korea Data Center. The Narrative of Woodcutter and Nymph of North Korea is basde on the proprieties of Confucianism and the populism which is focused on labor. and the story from beginning to middle is similar with original one, but the difference is intensified to the end. We say that this narration reflect the cultural policy of North Korea at the point of conclusion with reality which is very far from miracle tales and fantasy and pursuit real world story associated with common life. Old Story has common originality of South and North Korea. But After nation division. it is differentiated and it means each of country has own subconsciousness. The originality of disagreement is influenced by the national ideology over the personality and The Narrative of Woodcutter and Nymph of North Korea explain the this matter clearly.

This study was to examine the causative factors of family violence in married couples who were at the risk of family dissolution in a local community. The subjects in this study were 392 people, composed of 65 abusers and 64 victims, and 135 husbands and 128 wives from nonabusive families. After 219 items were initially selected, a exploratory factor analysis was carried out, resulting in 8 factors and 42 items: neglect of family (5 items), sexual neglect (7 items), drinking habits (4 items), dysfunctional communication (8 items), obsession over the spouse (4 items), child problems (3 items), adultery (7 items), and conflicts with family members (4 items). There were similarities as well as broad differences between the findings of this study and those of earlier studies. Adultery, drinking and dysfunctional communication on which earlier studies put consistent stress were identified as major causative factors of violence in this study as well. But sexual neglect, neglect of family, child problems and conflicts with family members to which earlier studies didn't pay a lot of attention were found to be as integral factors in this study. On the contrary, all the psychological factors such as personality that earlier studies focused on as the causes of family violence weren't considered to be influential in this study, with the exception of obsession.
